Endovascular aneurysm repair (EVAR) is becoming a mainstay in vascular surgery, both in metropolitan and regional hospitals. This review aims to assess the impact of hospital and surgeon volume on perioperative mortality specific to this surgery type to support the use of this treatment modality extensively. A literature search was performed on multiple dedicated medical databases using a detailed search strategy with terms focusing on hospital volume and EVARs. Inclusion and exclusion criteria were used to screen and evaluate suitable sources, focusing on operators and hospitals performing EVARs and the morbidity/mortality as outcomes. The results were then appraised using a PRISMA framework. We reviewed 45 articles. Twelve articles met inclusion criteria for complete review. There was no level 1 evidence, and only a single systematic review and meta-analysis. EVAR and thoracic EVAR perioperative mortality had no correlation with hospital volume. Limited evidence was presented for fenestrated EVAR, wheearch. To evaluate the effect of frailty assessed by the modified Frailty Index (mFI) on major adverse cardiac and cerebrovascular events (MACCE) in the elderly patients after endovascular aortic aneurysm repair (EVAR). This was a retrospective cohort study of elderly patients who underwent EVAR in a tertiary hospital. The main exposure was frailty status assessed by the mFI. The primary outcomes were 30-day and long-term MACCE. https://www.selleckchem.com/products/opb-171775.html The predictive ability of the mFI was compared with the Revised Cardiac Risk Index (RCRI) using net reclassification improvement (NRI) and integrated discrimination improvement (IDI) statistics. Of 749 participants, 134 (17.89%) were identified as frail and 185 (24.70%) as prefrail. Thirteen patients (1.74%) were lost in follow-up after surgery, and the median length of follow-up was 32.00months (range, 15.00-59.25months). Frailty was associated with a significantly increased risk of 30-day MACCE (adjusted odds ratio OR, 14.53; 95% confidence interval [CI], 4.59-46.04; P< .0001) andatients after EVAR, with improved discrimination and reclassification abilities compared with the RCRI. Frailty assessed by the mFI may serve as a useful predictor of both short-term and long-term MACCE in elderly patients after EVAR, with improved discrimination and reclassification abilities compared with the RCRI. Open repair of complex aortic aneurysms is frequently not an option for octogenarians because of prohibitive surgical risks. This study aimed to analyze the outcomes of fenestrated-branched endovascular aortic repair (F-BEVAR) in octogenarians (≥80years old) compared with nonoctogenarians (<80years old). We reviewed 893 patients with pararenal or extent I to V thoracoabdominal aneurysms, enrolled in six prospective physician-sponsored investigational device exemption studies from 2012 to 2018. All patients were treated with either company-manufactured off-the-shelf or patient-specific F-BEVAR stent grafts. Data analyzed included demographics, cardiovascular risk factors, history of active cancer, American Society of Anesthesiologists classification, aortic anatomy characteristics, and procedural data. End points included mortality, major adverse events (all-cause mortality, stroke, paralysis, acute kidney injury [RIFLE criteria], dialysis, myocardial infarction, respiratory failure, and bowel ischemia)rs. More extensive clinical experience and longer follow-up are needed to better delineate factors impacting longer term mortality. Despite small differences in demographics, anatomic factors, and procedural data, F-BEVAR was safe and effective with nearly identical early outcomes in octogenarians in these experienced aortic centers. More extensive clinical experience and longer follow-up are needed to better delineate factors impacting longer term mortality. Vascular micro-channels within chronic total occlusions (CTO) have been identified in histopathology and animal studies. They have been proposed as a potential path for achieving endovascular crossing via the lumen. There arecurrently no noninvasive means of imaging these structures. The aim of this study was to investigate whether contrast-enhanced ultrasound (CEUS) examination can identify micro-channels within CTO in humans. CTO within the femoropopliteal arteries were imaged with CEUS examination in 38 patients. Segments containing micro-channels were identified and their length measured. The proportion of occlusion length containing micro-channels was assessed for each case. Micro-channel appearances including linear or tortuous configuration, crossing of occlusion caps, and connections to vasa vasorum were recorded. The median CTO length was 17.0cm (interquartile range [IQR], 6.9-27.9cm) and median age of CTO was 12months (IQR, 6-16months). Micro-channels were identified in 92.1% of cases (35/38).history of femoropopliteal CTO. CEUS can be used to detect micro-channels in CTO in human femoropopliteal arteries. This imaging technique is safe and minimally invasive and may represent a practical method for selection of occlusion crossing method. Further work is required to determine whether identification of micro-channels can be used to improve treatment decision-making and provide a better understanding of the natural history of femoropopliteal CTO. To compare the surgical outcomes of benign and malignant carotid body tumor (CBT), and to evaluate the associated factors of malignant CBT. Patients who underwent surgical resection of CBT from 2005 to 2018 in a tertiary center were reviewed retrospectively. The common study follow-up end date was December 31, 2019. The tumor size was measured as the maximum transverse diameter on computed tomography scan. Surgical outcomes of benign and malignant CBT were compared. Associated factors of malignancy were analyzed by multivariate logistic analysis. There were 229 patients undergoing CBT resection. Sixteen patients were diagnosed with malignant CBT. The median follow-up time was 66months (range, 6-142months). Basic information including age, sex, course of disease, family history, lesion side, tumor size, and Shamblin classification showed no significant differences between the benign and malignant CBT groups. Patients with malignant CBTs showed a higher rate of preoperative symptoms (31.3% vs 12.2%; P< .

These data show that the 4CMenB vaccine can induce bactericidal antibodies against genetically representative meningococcal W, Y and X strains from Italy. For serogroup C, different susceptibilities to killing were observed for strains with similar antigenic repertoires.Current literature on aging in place highlights the socioemotional components that act as barriers to remaining in the home, but it often neglects actionable safety features of the home which may also pose a threat. Furthermore, this literature often neglects self-reported barriers to aging in place. Utilizing grounded theory, a retrospective review of home safety assessments completed in Philadelphia analyzed older adult reports to determine what factors older adults view as barriers to their aging in place plans. Overarching categories that were discovered through the data analysis process included barriers related to home mobility and safety, personal health, access to community services, home improvement and maintenance needs, general safety concerns, and bathroom safety. Results indicate that older adults can identify many barriers to aging within their home, but that accessing support and services to overcome these barriers requires additional resources and funding.Polyvinylchloride is universally agreed upon to be the material of choice for tubings and for containers for medical application. Many alterations of the chemical/physical surface conditions, mainly due to an altered extrusion process, could influence its biocompatibility by promoting platelet aggregation. Biocompatibility and safety of the medical device must be preserved, also monitoring the migration of additives within polyvinylchloride during the diffusion process. A large variety of methods are used to verify the correct composition and extrusion of polyvinylchloride but, generally, they need long experimental time and are expensive. The aim of the study is to propose a simple, economic and rapid approach based on Fourier transform-infrared spectroscopy and Coomassie Blue staining. The method has been used to detect chemical and morphological defects caused by an altered extrusion process on 20/75 polyvinylchloride tubings in a blind test. This approach positively identified altered samples in 80% of the cases. The suggested approach represents a reliable and versatile method to detect and monitor surface defects by an easy, inexpensive and reproducible method.Subperiosteal orbital haematoma (SOH) is an uncommon condition that involves bleeding within the potential space between the periosteum and orbital bone. This typically occurs within the superior orbit. If the SOH is large enough it can compress orbital structures and be sight threatening. Therefore, it is important for the clinician to recognize the potential causes for this phenomenon which will help guide the diagnosis. Herein we describe a unique case of unilateral SOH in a 47-year-old male following otherwise uncomplicated general anaesthesia. This occurred 6 weeks after a motorbike accident in which there was no facial/ocular injury. This case report identifies for the first time the potential for a late-onset SOH in the setting of a stressor event. It also highlights the potential for this condition to occur following general anaesthesia in a supine patient having a non-cardiac procedure, previously recognized as a potential stressor.Ketamine is an N-methyl-D-aspartate receptor antagonist with rapid antidepressant effects. Studies suggest that inhibition of nitric oxide synthesis plays a role in the mechanism of action of ketamine. This randomized, placebo-controlled study investigated whether co-administration of sodium nitroprusside, a nitric oxide donor, compared to placebo, would attenuate the antidepressant and dissociative effects of ketamine. Sixteen ketamine responders were randomized to a double-blind infusion of ketamine co-administered with placebo or sodium nitroprusside. Our findings show no difference between the two conditions suggesting that the nitric oxide pathway may not play a primary role in ketamine's antidepressant or dissociative effects. The study is registered at clinicaltrials.gov (NCT03102736).Ligustrazine, an alkaloid monomer extracted from Chuanxiong Rhizoma, has the function of protecting nerve cells. However, the effect and mechanism of ligustrazine on retinal ischemia/reperfusion (I/R) injury still need to be clarified. https://www.selleckchem.com/products/Abiraterone.html In our study, retinal ganglion cells (RGC-5) were used to establish a retinal I/R injury model by anaerobic cultivation. Cell viability, autophagy, and apoptosis were evaluated by cell counting kit 8 assay, transmission electron microscopy, and TUNEL staining after treatment with ligustrazine, PI3K inhibitor Ly294002, and/or mTOR inhibitor rapamycin, respectively. Besides, the levels of PI3K/Akt/mTOR pathway and autophagy-related proteins were determined by western blot. Moreover, one-way ANOVA was adopted for inter-group comparisons of measurement data. Our results demonstrated that low-concentration ligustrazine significantly enhanced cell viability and suppressed cell autophagy and apoptosis of RGC-5 cells after I/R injury, suggesting the protective effect of low-concentration ligustrazine on retinal I/R injury. Moreover, the alleviating effect of ligustrazine on RGC-5 with retinal I/R injury was mechanistically associated with the activation of the PI3K/Akt/mTOR pathway. In conclusion, low-concentration ligustrazine has a significant protective effect on RGC-5 cells with retinal I/R injury by activating the PI3K/Akt/mTOR pathway. To examine associations between the deep medullary vein white matter injury global severity scoring system and neurodevelopmental impairment. This is a prospective observational cohort study of infants born at ≥32 weeks, diagnosed with deep medullary vein thrombosis and infarction on neuroimaging in the first month of life. Developmental testing was performed using validated measures for early, preschool, and school-age follow-up. Nineteen (37%) patients had major neurodevelopmental impairment. Global severity score was higher among patients with neurodevelopmental impairment (21.6 vs 13.4, = .04). Overall, 78% of patients with epilepsy had neurodevelopmental impairment. A greater degree of asymmetry with right-sided injury predominance was associated with lower Bayley-III cognitive scores and presence of neurodevelopmental impairment ( < .01). Results suggest a need for targeted clinical surveillance for patients with a high global severity score and/or asymmetric, predominantly right cerebral white matter injury and for those who develop epilepsy.

We show that the C terminus and ATPase domain of SLFN11 are required for DDB1 binding and CDT1 degradation. Furthermore, we identify a therapy-relevant ATPase mutant (E669K) of the SLFN11 gene in human TCGA and show that the mutant contributes to chemoresistance and retarded CDT1 degradation. Taken together, our study reveals new chemotherapeutic insights on how targeting the ATR pathway overcomes chemoresistance of SLFN11-deficient cancers. It also demonstrates that SLFN11 irreversibly arrests replication by degrading CDT1 through the DDB1-CUL4CDT2 ubiquitin ligase.Macrophages are intimately involved in the pathophysiology of endometriosis, a chronic inflammatory disorder characterized by the growth of endometrial-like tissue (lesions) outside the uterus. By combining genetic and pharmacological monocyte and macrophage depletion strategies we determined the ontogeny and function of macrophages in a mouse model of induced endometriosis. We demonstrate that lesion-resident macrophages are derived from eutopic endometrial tissue, infiltrating large peritoneal macrophages (LpM) and monocytes. Furthermore, we found endometriosis to trigger continuous recruitment of monocytes and expansion of CCR2+ LpM. https://www.selleckchem.com/products/rk-701.html Depletion of eutopic endometrial macrophages results in smaller endometriosis lesions, whereas constitutive inhibition of monocyte recruitment significantly reduces peritoneal macrophage populations and increases the number of lesions. Reprogramming the ontogeny of peritoneal macrophages such that embryo-derived LpM are replaced by monocyte-derived LpM decreases the number of lesions that develop. We propose a putative model whereby endometrial macrophages are "proendometriosis" while newly recruited monocyte-derived macrophages, possibly in LpM form, are "antiendometriosis." These observations highlight the importance of monocyte-derived macrophages in limiting disease progression.Mechanical impedance limits soil exploration and resource capture by plant roots. We examine the role of root anatomy in regulating plant adaptation to mechanical impedance and identify a root anatomical phene in maize (Zea mays) and wheat (Triticum aestivum) associated with penetration of hard soil Multiseriate cortical sclerenchyma (MCS). We characterize this trait and evaluate the utility of MCS for root penetration in compacted soils. Roots with MCS had a greater cell wall-to-lumen ratio and a distinct UV emission spectrum in outer cortical cells. Genome-wide association mapping revealed that MCS is heritable and genetically controlled. We identified a candidate gene associated with MCS. Across all root classes and nodal positions, maize genotypes with MCS had 13% greater root lignin concentration compared to genotypes without MCS. Genotypes without MCS formed MCS upon exogenous ethylene exposure. Genotypes with MCS had greater lignin concentration and bending strength at the root tip. In controlled environments, MCS in maize and wheat was associated improved root tensile strength and increased penetration ability in compacted soils. Maize genotypes with MCS had root systems with 22% greater depth and 49% greater shoot biomass in compacted soils in the field compared to lines without MCS. Of the lines we assessed, MCS was present in 30 to 50% of modern maize, wheat, and barley cultivars but was absent in teosinte and wild and landrace accessions of wheat and barley. MCS merits investigation as a trait for improving plant performance in maize, wheat, and other grasses under edaphic stress. As schools reopen nationwide, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in youth settings remains a concern. Here, we describe transmission of SARS-CoV-2 among >6800 youth and staff at YMCA of the Triangle day camps in North Carolina (March to August 2020). We performed a retrospective analysis of deidentified SARS-CoV-2 cases reported by YMCA day camps in 6 counties (Chatham, Durham, Johnston, Lee, Orange, Wake) over 147 days. Inclusion criteria were youth and staff who enrolled or worked in camps during the study period. Individual-level youth and staff demographics (age, sex, race and ethnicity) were self-reported and linked to SARS-CoV-2 case data by using unique identifiers. Youth ( = 5344; 66% white, 54% male, mean age 8.5 years) had a mean camp attendance rate of 88%; staff ( = 1486) were 64% white and 60% female (mean age 22 years). Seventeen primary SARS-CoV-2 infections occurred during the study period among 9 youth (mean age 9.7 years) and 8 staff (mean ageweigh the risk of viral transmission. Transmasculine individuals, those assigned female sex at birth but who identify as masculine, have high rates of suicidal behavior and often suffer from chest dysphoria (discomfort and distress from unwanted breast development). Growing numbers of transmasculine youth are pursuing definitive treatment with masculinizing chest surgery (MCS), and adult studies reveal marked benefits of MCS, although little is known about the impact of chest dysphoria on transmasculine youth or the optimal timing of MCS. In this study, we aimed to explore youth experiences of chest dysphoria and the impact of MCS. Transmasculine youth aged 13 to 21 were recruited from a pediatric hospital-based gender clinic. Participants completed a semistructured qualitative interview exploring the experience of chest dysphoria and thoughts about or experiences with MCS. Interview transcripts were coded by 3 investigators employing modified grounded theory, with the median interrater reliability at κ = 0.92. Subjects ( = 30) were a mealop patient-reported outcome measures to assess the impact of chest dysphoria and MCS.Burkholderia pseudomallei is a Gram-negative bacterium that causes the sapronotic disease melioidosis. An outbreak in 2003 in the state of Ceara, Brazil, resulted in subsequent surveillance and environmental sampling which led to the recognition of B. pseudomallei as an endemic pathogen in that area. From 2003 to 2015, 24 clinical and 12 environmental isolates were collected across Ceara along with one from the state of Alagoas. Using next-generation sequencing, multilocus sequence typing, and single nucleotide polymorphism analysis, we characterized the genomic diversity of this collection to better understand the population structure of B. pseudomallei associated with Ceara. We found that the isolates in this collection form a distinct subclade compared to other examples from the Western Hemisphere. Substantial genetic diversity among the clinical and environmental isolates was observed, with 14 sequence types (STs) identified among the 37 isolates. Of the 31,594 core single-nucleotide polymorphisms (SNPs) identified, a high proportion (59%) were due to recombination.

o improve patient outcome in a preselected patient population. In the authors' opinion, critically ill COVID-19 patients should be treated in an ARDS center provided that sufficient resources are available.Most small rodent populations in the world have fascinating population dynamics. In the northern hemisphere, voles and lemmings tend to show population cycles with regular fluctuations in numbers. In the southern hemisphere, small rodents tend to have large amplitude outbreaks with less regular intervals. In the light of vast research and debate over almost a century, we here discuss the driving forces of these different rodent population dynamics. We highlight ten questions directly related to the various characteristics of relevant populations and ecosystems that still need to be answered. This overview is not intended as a complete list of questions but rather focuses on the most important issues that are essential for understanding the generality of small rodent population dynamics. Awidespread assumption is that people learn certain ways of dealing with media in the course of their youth and adult life, which later make it difficult for them to develop new patterns of media usage. Beyond theoretical assumptions, there is alack of exploratory studies that investigate the conditions under which older people pick up new media technologies and integrate them into their everyday lives. From October 2019 to March 2020 a total of 16 semi-standardized individual interviews were carried out with people aged between 80 and 92years. The interviewees had learned to use adigital medium on their own in the past few years and had integrated this into their everyday lives. The interviewees appropriated new media in atargeted manner. It is noticeable that processes of appropriation were largely triggered by severe changes in living conditions. In addition, most of the interviewees learned how to use adigital medium because they wanted to use specific functions. With some delay, new options for onl use new media in old age. Participatory health research is gaining increasing recognition in the public health sector. The people whose lives or work are central to wicked issues around health inequalities are integrated into the projects. Including diverse forms of knowledge and perspectives has the capability of strengthening health equity in specific settings. That proffers agency to the voices of those who are seldom heard. Often, participatory health research (PHR) is done with communities. Finding the truly isolated - those who are not connected to others or to services, the seldom heard - presents achallenge for research. Without hearing the voices of those most distanced from mainstream discourse we run the risk of misunderstanding issues pertinent to their lives. This narrative overview highlights this problem and aims to contribute asolution approach for research practice. An extensive literature review for participatory research references in the German language was used and the international literature was also screened. https://www.selleckchem.com/products/cbd3063.html Furthermore, the processes of three participatory research projects were evaluated. The specified strategies to involve the seldom heard refer to lowered systemic barriers and improved local capacity for their participation. For example, before research can start, time should be given for apreparatory phase. This can be used to invest in relationships and co-operation to bridge the distance to research.

This can be used to invest in relationships and co-operation to bridge the distance to research.Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder with limited approved pharmacological treatment options and high symptom burden. Therefore, real-life prescription patterns may differ from guideline recommendations, especially in psychiatric inpatient settings. The European Drug Safety Program in Psychiatry ("Arzneimittelsicherheit in der Psychiatrie", AMSP) collects inpatients' prescription rates cross-sectionally twice a year in German-speaking psychiatric hospitals. For this study, the AMSP database was screened for psychiatric inpatients with a primary diagnosis of PTSD between 2001 and 2017. N = 1,044 patients with a primary diagnosis of PTSD were identified with 89.9% taking psychotropics. The average prescription rate was 2.4 (standard deviation 1.5) psychotropics per patient with high rates of antidepressant drugs (72.0%), antipsychotics drugs (58.4%) and tranquilizing drugs (29.3%). The presence of psychiatric comorbidities was associated with higher rates of psychotropic drug use. The most often prescribed substances were quetiapine (24.1% of all patients), lorazepam (18.1%) and mirtazapine (15.0%). The use of drugs approved for PTSD was low (sertraline 11.1%; paroxetine 3.7%). Prescription rates of second-generation antipsychotic drugs increased, while the use of tranquilizing drugs declined over the years. High prescription rates and extensive use of sedative medication suggest a symptom-driven prescription (e.g., hyperarousal, insomnia) that can only be explained to a minor extent by existing comorbidities. The observed discrepancy with existing guidelines underlines the need for effective pharmacological and psychological treatment options in psychiatric inpatient settings.Approximately 70-80% of patients with cT1-2N0 oral squamous cell carcinoma (OSCC) ultimately prove to have no cancer in the cervical lymphatics on final pathology after selective neck dissection. As a result, sentinel lymph node biopsy (SLNB) has been adopted during the last decade as a diagnostic staging method to intelligently identify patients who would benefit from formal selective lymphadenectomy or neck irradiation. While not yet universally accepted, SLNB is now incorporated in many national guidelines. SLNB offers a less invasive alternative to elective neck dissection (END), and has some advantages and disadvantages. SLNB can assess the individual drainage pattern and, with step serial sectioning and immunohistochemistry (IHC), can enable the accurate detection of micrometastases and isolated tumor cells (ITCs). Staging of the neck is improved relative to END with routine histopathological examination. The improvements in staging are particularly notable for the contralateral neck and the pretreated neck.

More research investigating moderating and mediating effects on the associations between urban dwelling and eating disorder is needed as well as studies of more sexually and age diverse populations. It does not seem likely that metropolitan dwelling in itself is a major risk factor for developing an eating disorder. However, when accompanied by other sociodemographic effects, there may well be an increase in eating disorder risk. There are opportunities for planners to design cities to be supportive of peoples' eating and mental health in general. More research investigating moderating and mediating effects on the associations between urban dwelling and eating disorder is needed as well as studies of more sexually and age diverse populations. Agitation associated with schizophrenia remains an important clinical concern and if not managed effectively, can escalate into aggressive behavior. https://www.selleckchem.com/products/sn-011-gun35901.html This is a review of the recent biomedical literature on agitation in individuals with schizophrenia. Themes in the recent literature include consideration of comorbidities such as cigarette smoking and cannabis use. Surveys reveal that pharmacological approaches to manage agitation have changed little, with haloperidol remaining in common use and intramuscular administration of antipsychotics and/or benzodiazepines being frequently administered to more severely agitated/aggressive individuals. Of note, ketamine has been recently adopted for use in severe agitation in medical emergency departments, but the risk of this medication for people with schizophrenia is unclear. At present, inhaled loxapine remains the only rapidly acting noninjectable FDA-approved treatment for agitation associated with schizophrenia. In development is an intranasal formulation for olanzapine (a well characterized atypical antipsychotic already approved to treat agitation) and a sublingual film for dexmedetomidine (an α2-adrenergic agonist used as an anesthetic and now being repurposed). Comorbidities can contribute to agitation and can make an accurate differential diagnosis challenging. The ongoing development of rapidly acting novel formulations of antiagitation medications, if successful, may facilitate clinical treatment by providing additional options. Comorbidities can contribute to agitation and can make an accurate differential diagnosis challenging. The ongoing development of rapidly acting novel formulations of antiagitation medications, if successful, may facilitate clinical treatment by providing additional options. Neurocognitive disorders are associated with tremendous burden at the level of the individual, the care giver, and society at large. No effective treatments have been discovered to date. Noninvasive brain stimulation (NIBS) comprises several promising interventions that have been studied in Alzheimer's disease and related dementias. Most recent studies have tested transcranial direct current stimulation or repetitive transcranial magnetic stimulation on their own or in combination with other interventions, particularly cognitive training. While most studies were proof-of-principle studies with small sample sizes, combination and long-duration protocols seem to be promising approaches to pursue. Some studies also investigated novel neurophysiological markers as predictors of response to NIBS. NIBS presents several interventional options that are ready to be evaluated using well powered, long-duration trials. These future studies should build on the promising leads from the current literature, including the potential advantage of combining NIBS with other interventions; the delivery of interventions for long durations to assess long-term impact; and the use of neurophysiological markers that could optimize the personalization and efficacy of NIBS.

The COVID-19 infection results in various viral-related physical and mental health problems, joined with the long-term psychological impact of the pandemic in general. However, the accompanying neurocognitive changes remain poorly understood. We synthetize the current knowledge of viral (SARS-CoV-2) induced inflammation, mechanisms to viral entry into the central nervous system and altered neurotransmitter systems to provide an informed neurobiological explanation for the rise of neurocognitive disorders (defined as per the DSM-5 criteria). The mild and major neurocognitive disorder symptoms due to the COVID-19 pandemic provide a unique opportunity to address the early changes underlying neurocognitive impairment at both clinical and molecular level. We discuss the utilization of the available evidence for their management and future novel therapeutic opportunities.

We discuss the utilization of the available evidence for their management and future novel therapeutic opportunities. Over 70 million people worldwide, including those with neurodegenerative disease (NDD), have been diagnosed with coronavirus disease 2019 (COVID-19) to date. We review outcomes in patients with NDD and COVID-19 and discuss the hypothesis that due to putative commonalities of neuropathogenesis, COVID-19 may unmask or trigger NDD in vulnerable individuals. Based on a systematic review of published literature, patients with NDD, including dementia, Parkinson's disease, and multiple sclerosis (MS) make up a significant portion of hospitalized COVID-19 patients. Such patients are likely to present with altered mental status or worsening of their preexisting neurological symptoms. Patients with NDD and poor outcomes often have high-risk comorbid conditions, including advanced age, hypertension, diabetes, obesity, and heart/lung disease. Patients with dementia including Alzheimer's disease are at higher risk for hospitalization and death, whereas those with preexisting Parkinson's disease are not. MS patients have good outcomes and disease modifying therapies do not increase the risk for severe disease.

In this review, a total of 134 journal articles (from 2017 to 2019) were reviewed and the chemical structures of 449 new metabolites, including polyketides, terpenoids, steroids and so on, were summarized. Besides, various biological activities and structure-activity relationship of some compounds were aslo described.The development of renewable energy technologies is of global importance. To realize a sustainable society, fossil-resource-independent technologies, such as solar- and wind-power generation, should be widely adopted. Pressure retarded osmosis (PRO) is one such potential renewable energy technology. PRO requires salt water and fresh water, both of which can be found at seawater desalination plants. The total power generation capacity of PRO, using concentrated seawater and fresh water, is 3 GW. A large amount of energy is required for seawater desalination; therefore, the introduction of renewable energy should be prioritized. Kyowakiden Industry Co., Ltd., has been working on introducing PRO to seawater desalination plants since 2001 and is attracting attention for its ongoing PRO pilot plant with a scale of 460 m3/d, using concentrated seawater and treated sewage water. In this study, we evaluated the feasibility of introducing PRO in existing desalination plants. The feasibility was examined based on technology, operation, and economy. Based on the number of seawater desalination plants in each country and the electricity charges, it was determined whether the introduction of PRO would be viable. Advanced nanobiotechnology provides safe and efficient drug delivery systems to deliver chemotherapy that targets cancer cells efficiently. A polymeric-magnetic nanocarrier was composed of a dextran (DEX) shell, a superparamagnetic iron oxide (SPION) core and was conjugated with folate (FA) to carry the anticancer drug vincristine (VNC) in Tera-1 testicular tumor cells. The molecular mechanisms by which apoptosis was induced were analyzed using flow cytometry and qPCR, which exhibited anticancer activity of nanoparticles (NPs). This nanocarrier revealed a controlled release of VNC in citrate and phosphate buffer solutions that were maintained at pH 5.5 and pH 7.4, respectively. The Inhibitory concentration (IC50) values were greater than 5 mg/mL and displayed ten times higher cytotoxicity than the comparable free drug concentration. The Caspase-9 and P53 expressions were increased, whereas P21 and AKt1 decreased noticeably in the treated cells. The results point to the possible activation of apoptosis following treatment with NPs loaded with vincristine.

Plant phytochemicals have been considered in alternative, or complementary, prevention and treatment strategies. Herbals are consumed as such, or as food supplements, whose consumption has recently increased. However, these products are not exempt from adverse effects and pharmacological interactions, presenting a special risk in aged, polymedicated individuals. Understanding pharmacokinetic and pharmacodynamic interactions is warranted to avoid undesirable adverse drug reactions, which may result in unwanted side-effects or therapeutic failure. The present study reviews the potential interactions between selected bioactive compounds (170) used by seniors for cognitive enhancement and representative drugs of 10 pharmacotherapeutic classes commonly prescribed to the middle-aged adults, often multimorbid and polymedicated, to anticipate and prevent risks arising from their co-administration. A literature review was conducted to identify mutual targets affected (inhibition/induction/substrate), the frequency of which was taken as a measure of potential interaction. Although a limited number of drugs were studied, from this work, interaction with other drugs affecting the same targets may be anticipated and prevented, constituting a valuable tool for healthcare professionals in clinical practice.Atherosclerosis is a hallmark of most cardiovascular diseases. The implication of macrophages in this pathology is widely documented, notably for their contribution to lipid accumulation within the arterial wall, associated with oxidative stress and inflammation processes. In order to prevent or limit the atherosclerosis damage, nutritional approaches and medicinal plant-based therapies need to be considered. In Reunion Island, medicinal plant-based beverages are traditionally used for their antioxidant, lipid-lowering and anti-inflammatory properties. The aim of our study was to assess the protective effects of eight medicinal plant decoctions in an in vitro model of RAW 264.7 murine macrophages exposed to pro-atherogenic conditions (oxidized low-density lipoproteins-ox-LDL-E. coli Lipopolysaccharides-LPS). The impact of polyphenol-rich medicinal plant decoctions on cell viability was evaluated by Neutral Red assay. Fluorescent ox-LDL uptake was assessed by flow cytometry and confocal microscopy. Activation of NF-κB was evaluated by quantification of secreted alkaline phosphatase in RAW-Blue™ macrophages. Our results show that medicinal plant decoctions limited the cytotoxicity induced by ox-LDL on macrophages. Flow cytometry analysis in macrophages demonstrated that medicinal plant decoctions from S. cumini and P. mauritianum decreased ox-LDL uptake and accumulation by more than 70%. In addition, medicinal plant decoctions also inhibited NF-κB pathway activation in the presence of pro-inflammatory concentrations of E. coli LPS. Our data suggest that medicinal plant decoctions exert protective effects on ox-LDL-induced cytotoxicity and limited macrophage lipid uptake. Moreover, herbal preparations displayed anti-inflammatory properties on macrophages that can be of interest for limiting the atherosclerotic process.

In this review, a total of 134 journal articles (from 2017 to 2019) were reviewed and the chemical structures of 449 new metabolites, including polyketides, terpenoids, steroids and so on, were summarized. Besides, various biological activities and structure-activity relationship of some compounds were aslo described.The development of renewable energy technologies is of global importance. To realize a sustainable society, fossil-resource-independent technologies, such as solar- and wind-power generation, should be widely adopted. Pressure retarded osmosis (PRO) is one such potential renewable energy technology. PRO requires salt water and fresh water, both of which can be found at seawater desalination plants. The total power generation capacity of PRO, using concentrated seawater and fresh water, is 3 GW. A large amount of energy is required for seawater desalination; therefore, the introduction of renewable energy should be prioritized. Kyowakiden Industry Co., Ltd., has been working on introducing PRO to seawater desalination plants since 2001 and is attracting attention for its ongoing PRO pilot plant with a scale of 460 m3/d, using concentrated seawater and treated sewage water. In this study, we evaluated the feasibility of introducing PRO in existing desalination plants. The feasibility was examined based on technology, operation, and economy. Based on the number of seawater desalination plants in each country and the electricity charges, it was determined whether the introduction of PRO would be viable. Advanced nanobiotechnology provides safe and efficient drug delivery systems to deliver chemotherapy that targets cancer cells efficiently. A polymeric-magnetic nanocarrier was composed of a dextran (DEX) shell, a superparamagnetic iron oxide (SPION) core and was conjugated with folate (FA) to carry the anticancer drug vincristine (VNC) in Tera-1 testicular tumor cells. The molecular mechanisms by which apoptosis was induced were analyzed using flow cytometry and qPCR, which exhibited anticancer activity of nanoparticles (NPs). This nanocarrier revealed a controlled release of VNC in citrate and phosphate buffer solutions that were maintained at pH 5.5 and pH 7.4, respectively. The Inhibitory concentration (IC50) values were greater than 5 mg/mL and displayed ten times higher cytotoxicity than the comparable free drug concentration. The Caspase-9 and P53 expressions were increased, whereas P21 and AKt1 decreased noticeably in the treated cells. The results point to the possible activation of apoptosis following treatment with NPs loaded with vincristine.

Plant phytochemicals have been considered in alternative, or complementary, prevention and treatment strategies. Herbals are consumed as such, or as food supplements, whose consumption has recently increased. However, these products are not exempt from adverse effects and pharmacological interactions, presenting a special risk in aged, polymedicated individuals. Understanding pharmacokinetic and pharmacodynamic interactions is warranted to avoid undesirable adverse drug reactions, which may result in unwanted side-effects or therapeutic failure. The present study reviews the potential interactions between selected bioactive compounds (170) used by seniors for cognitive enhancement and representative drugs of 10 pharmacotherapeutic classes commonly prescribed to the middle-aged adults, often multimorbid and polymedicated, to anticipate and prevent risks arising from their co-administration. A literature review was conducted to identify mutual targets affected (inhibition/induction/substrate), the frequency of which was taken as a measure of potential interaction. Although a limited number of drugs were studied, from this work, interaction with other drugs affecting the same targets may be anticipated and prevented, constituting a valuable tool for healthcare professionals in clinical practice.Atherosclerosis is a hallmark of most cardiovascular diseases. The implication of macrophages in this pathology is widely documented, notably for their contribution to lipid accumulation within the arterial wall, associated with oxidative stress and inflammation processes. In order to prevent or limit the atherosclerosis damage, nutritional approaches and medicinal plant-based therapies need to be considered. In Reunion Island, medicinal plant-based beverages are traditionally used for their antioxidant, lipid-lowering and anti-inflammatory properties. The aim of our study was to assess the protective effects of eight medicinal plant decoctions in an in vitro model of RAW 264.7 murine macrophages exposed to pro-atherogenic conditions (oxidized low-density lipoproteins-ox-LDL-E. coli Lipopolysaccharides-LPS). The impact of polyphenol-rich medicinal plant decoctions on cell viability was evaluated by Neutral Red assay. Fluorescent ox-LDL uptake was assessed by flow cytometry and confocal microscopy. Activation of NF-κB was evaluated by quantification of secreted alkaline phosphatase in RAW-Blue™ macrophages. Our results show that medicinal plant decoctions limited the cytotoxicity induced by ox-LDL on macrophages. Flow cytometry analysis in macrophages demonstrated that medicinal plant decoctions from S. cumini and P. mauritianum decreased ox-LDL uptake and accumulation by more than 70%. In addition, medicinal plant decoctions also inhibited NF-κB pathway activation in the presence of pro-inflammatory concentrations of E. coli LPS.

In this paper, the Voronoimosaic model and the cohesive element method were used to simulate crack propagation in the microstructure of alumina/graphene composite ceramic tool materials. The effects of graphene characteristic size and volume content on the crack propagation behavior of microstructure model of alumina/graphene composite ceramics under different interfacial bonding strength were studied. When the phase interface is weak, the average energy release rate is the highest as the short diameter of graphene is 10-50 nm and the long diameter is 1600-2000 nm. https://www.selleckchem.com/products/mavoglurant.html When the phase interface is strong, the average energy release rate is the highest as the short diameter of graphene is 50-100 nm and the long diameter is 800-1200 nm. When the volume content of graphene is 0.50 vol.%, the average energy release rate reaches the maximum. When the velocity load is 0.005 m s-1, the simulation result is convergent. It is proven that the simulation results are in good agreement with the experimental phenomena.Identification of health priorities is concerned with equitable distribution of resources and is an important part of strategic planning in the health care system. The aim of this article is to describe health priorities in the Polish health care system from the patients' perspective. The study included 533 patients hospitalized in the Lodz region. The average age of the respondents was 48.5 years and one third (36.6%) had university education. Most of the respondents (64.9%) negatively assessed the functioning of the health care system in Poland. Most of them claimed the following aspects require improvements financing health services (85.8%), determining priorities in health care (80.3%), the role of health insurance (80.3%), and medical education (70.8%). Over 70% of the respondents agreed the role of politicians in designing and implementing health system reforms should be limited. The fact that the respondents so negatively assessed the Polish health care system implies there is a need for full discussion on redefining health priorities.Recently, there has been a paradigm shift from conventional therapies to relatively safer phytotherapies. This divergence is crucial for the management of various chronic diseases. Okra (Abelmoschus esculentus L.) is a popular vegetable crop with good nutritional significance, along with certain therapeutic values, which makes it a potential candidate in the use of a variety of nutraceuticals. Different parts of the okra fruit (mucilage, seed, and pods) contain certain important bioactive components, which confer its medicinal properties. The phytochemicals of okra have been studied for their potential therapeutic activities on various chronic diseases, such as type-2 diabetes, cardiovascular, and digestive diseases, as well as the antifatigue effect, liver detoxification, antibacterial, and chemo-preventive activities. Moreover, okra mucilage has been widely used in medicinal applications such as a plasma replacement or blood volume expanders. Overall, okra is considered to be an easily available, low-cost vegetable crop with various nutritional values and potential health benefits. Despite several reports about its therapeutic benefits and potential nutraceutical significance, there is a dearth of research on the pharmacokinetics and bioavailability of okra, which has hampered its widespread use in the nutraceutical industry. This review summarizes the available literature on the bioactive composition of okra and its potential nutraceutical significance. It will also provide a platform for further research on the pharmacokinetics and bioavailability of okra for its possible commercial production as a therapeutic agent against various chronic diseases.The current social, health, and educational changes in society require an adequate response in school-based physical activity (PA), including physical education (PE) lessons. The objective of this study was to identify the real average step counts of Czech and Polish adolescents during PE lessons, and propose recommendations for improving PE programs. This research was carried out in 143 Czech and 99 Polish schools. In the research, a total of 4911 adolescents aged 12-18 years were analyzed as part of teaching practice and 1827 in the context of habitual school practice. Steps were monitored using pedometers. The average step count per PE lesson was 2390 in Czech and Polish boys, while girls achieved 1851 steps. In both countries, boys were subject to greater physical strain in PE lessons compared to girls, both in teaching practice (F(4088,3) = 154.49, p less then 0.001, ηp2 = 0.102) and school practice (F(1552,3) = 70.66, p less then 0.001, ηp2 = 0.103). Therefore, the priority in PE lessons is to increase the amount of PA for girls, achieve the objectives of PE during PA, and use wearables to improve awareness of PA and improve physical literacy, as well as to support hybrid and online PE as a complement to traditional PE.Road traffic crashes cause fatalities and injuries of both drivers/passengers in vehicles and pedestrians outside, thus challenge public health especially in big cities in developing countries like China. Previous efforts mainly focus on a specific crash type or causation to examine the crash characteristics in China while lacking the characteristics of various crash types, factors, and the interplay between them. This study investigated the crash characteristics in Shenzhen, one of the biggest four cities in China, based on the police-reported crashes from 2014 to 2016. The descriptive characteristics were reported in detail with respect to each of the crash attributes. Based on the recorded crash locations, the land-use pattern was obtained as one of the attributes for each crash. Then, the relationship between the attributes in motor-vehicle-involved crashes was examined using the Bayesian network analysis. We revealed the distinct crash characteristics observed between the examined levels of each attribute, as well the interplay between the attributes. This study provides an insight into the crash characteristics in Shenzhen, which would help understand the driving behavior of Chinese drivers, identify the traffic safety problems, guide the research focuses on advanced driver assistance systems (ADASs) and traffic management countermeasures in China.

Multinucleated giant cells (MGCs) are prominent in foreign body granulomas, infectious and inflammatory processes, and auto-immune, neoplastic and genetic disorders, but the molecular determinants that specify the formation and function of these cells are not defined. Here, using tandem mass tag-mass spectrometry, we identified a differentially upregulated protein, C-type lectin domain family 10 member (herein denoted CD301, also known as CLEC10A), that was strongly upregulated in mouse RAW264.7 macrophages and primary murine macrophages undergoing interleukin (IL-4)-induced MGC formation. CD301+ MGCs were identified in biopsy specimens of human inflammatory lesions. Function-inhibiting CD301 antibodies or CRISPR/Cas9 deletion of the two mouse CD301 genes (Mgl1 and Mgl2) inhibited IL-4-induced binding of N-acetylgalactosamine-coated beads by 4-fold and reduced MGC formation by 2.3-fold (P less then 0.05). IL-4-driven fusion and MGC formation were restored by re-expression of CD301 in the knockout cells. We conclude that in monocytes, IL-4 increases CD301 expression, which mediates intercellular adhesion and fusion processes that are required for the formation of MGCs.This article has an associated First Person interview with the first author of the paper.Using a longitudinal dataset linking biometric and survey data from several cohorts of young adults before and during the COVID-19 pandemic ([Formula see text]), we document large disruptions to physical activity, sleep, time use, and mental health. At the onset of the pandemic, average steps decline from 10,000 to 4,600 steps per day, sleep increases by 25 to 30 min per night, time spent socializing declines by over half to less than 30 min, and screen time more than doubles to over 5 h per day. Over the course of the pandemic from March to July 2020 the proportion of participants at risk for clinical depression ranges from 46% to 61%, up to a 90% increase in depression rates compared to the same population just prior to the pandemic. Our analyses suggest that disruption to physical activity is a leading risk factor for depression during the pandemic. However, restoration of those habits through a short-term intervention does not meaningfully improve mental well-being.The contributions of asymptomatic infections to herd immunity and community transmission are key to the resurgence and control of COVID-19, but are difficult to estimate using current models that ignore changes in testing capacity. Using a model that incorporates daily testing information fit to the case and serology data from New York City, we show that the proportion of symptomatic cases is low, ranging from 13 to 18%, and that the reproductive number may be larger than often assumed. Asymptomatic infections contribute substantially to herd immunity, and to community transmission together with presymptomatic ones. If asymptomatic infections transmit at similar rates as symptomatic ones, the overall reproductive number across all classes is larger than often assumed, with estimates ranging from 3.2 to 4.4. If they transmit poorly, then symptomatic cases have a larger reproductive number ranging from 3.9 to 8.1. Even in this regime, presymptomatic and asymptomatic cases together comprise at least 50% of the force of infection at the outbreak peak. We find no regimes in which all infection subpopulations have reproductive numbers lower than three. These findings elucidate the uncertainty that current case and serology data cannot resolve, despite consideration of different model structures. They also emphasize how temporal data on testing can reduce and better define this uncertainty, as we move forward through longer surveillance and second epidemic waves. Complementary information is required to determine the transmissibility of asymptomatic cases, which we discuss. Regardless, current assumptions about the basic reproductive number of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) should be reconsidered.The investigation of migratory patterns during the SARS-CoV-2 pandemic before spring 2020 border closures in Europe is a crucial first step toward an in-depth evaluation of border closure policies. Here we analyze viral genome sequences using a phylodynamic model with geographic structure to estimate the origin and spread of SARS-CoV-2 in Europe prior to border closures. Based on SARS-CoV-2 genomes, we reconstruct a partial transmission tree of the early pandemic and coinfer the geographic location of ancestral lineages as well as the number of migration events into and between European regions. https://www.selleckchem.com/products/Abiraterone.html We find that the predominant lineage spreading in Europe during this time has a most recent common ancestor in Italy and was probably seeded by a transmission event in either Hubei, China or Germany. We do not find evidence for preferential migration paths from Hubei into different European regions or from each European region to the others. Sustained local transmission is first evident in Italy and then shortly thereafter in the other European regions considered. Before the first border closures in Europe, we estimate that the rate of occurrence of new cases from within-country transmission was within the bounds of the estimated rate of new cases from migration. In summary, our analysis offers a view on the early state of the epidemic in Europe and on migration patterns of the virus before border closures. This information will enable further study of the necessity and timeliness of border closures. The COVID-19 pandemic poses new challenges to health care providers and the delivery of continuous care. Although many diabetes technologies, such as insulin pumps and continuous glucose monitors, have been established, the data from these devices are rarely assessed. Furthermore, telemedicine has not been sufficiently integrated into clinical workflows. We sought to remotely support children with type 1 diabetes and their caregivers, enhance the clinical outcomes and quality of life of children with diabetes, increase multiple stakeholders' engagement with digital care via a participatory approach, evaluate the feasibility of using an interoperable open-source platform in a university hospital setting, and analyze the success factors and barriers of transitioning from conventional care to digital care. Service design methods were used to adapt clinical workflows. Remote consultations were performed on a monthly and on-demand basis. Diabetes device data were uploaded from patients' homes to an open-source platform.

NC-derived EGFP cells co-expressing p75NTR was detected in cord blood of P0-Cre/Floxed-EGFP reporter mice. We found that freshly isolated HUCB mononuclear cells contained 0.23% of p75NTR cells. Isolated p75NTR cells from HUCB efficiently formed neurospheres and could differentiate into neuronal and glial cell lineages. The p75NTR cells expressed a set of NC-associated genes and undifferentiated neural cell marker genes before and after the culture. These findings revealed that HUCB contained the p75NTR NC-like progenitor cell population which have the self-renewal capacity and the potential to differentiate into both neuronal and glial cell lineages. These findings revealed that HUCB contained the p75NTR+ NC-like progenitor cell population which have the self-renewal capacity and the potential to differentiate into both neuronal and glial cell lineages.A revolutionary new approach to produce efficient cells is to induce transdifferentiation to make it conventional in therapeutic strategies. In this paper, we describe a brief cocktail of small molecules including Dorsomorphin (DSM) and Trichostatin A (TSA) to produce safe neuroectodermal cells as a resource to produce various types of nervous system cells for a safe cytotherapy. Furthermore, in order to optimize this strategy, we implemented a cocktail of neurotrophic factors to enhance the viability of the cell. This modification was accompanied by pretreatment of the culture dishes with a combination of poly-l-ornithine and laminin and fibronectin. In order to decrease the length of protocol and transdifferentiation variation concomitantly, TSA was utilized as an epigenetic modulator. Finally, this improved protocol mediated neuroectodermal conversion of human fibroblasts within 12 days with an average efficiency of 24%, promising a fast strategy to produce neuroectodermal cells applicable for therapeutic purposes in neural damages. https://www.selleckchem.com/products/sf2312.html Here we induce neural cells by a cocktail consists of two small molecules of DSM and TSA. Our protocol is a 12 day protocol with the efficiency of 24% which is a more efficient one in comparison to previous protocols inducing neural cells. Consequently, our protocol shortens the path of in vitro and preclinical studies in the field of neural conversion and neuroregeneration.Loneliness affects group-living mammals triggering a cascade of stress-dependent physiological disorders. Indeed, social isolation stress is a major risk factor for several neuropsychiatric disorders including anxiety and depression. Furthermore, social isolation has a negative impact on health and fitness. However, the neurobiological consequences of long-term chronic social isolation stress (LTCSIS) manifested during the adulthood of affected individuals are not fully understood. Our study assessed the impact of LTCSIS and social buffering (re-socialization) on the behavioural performance and social-affective brain-related proteins in diurnal, social, and long-lived Octodon degus (degus). Thereby, anxiety-like and social behaviour, and social recognition memory were assessed in male and female animals subjected to a variety of stress-inducing treatments applied from post-natal and post-weaning until their adulthood. Additionally, we evaluated the relationship among LTCSIS, Oxytocin levels (OXT), and OXT-Ca2+-signalling proteins in the hypothalamus, the hippocampus, and the prefrontal cortex. Our findings suggest that LTCSIS induces anxiety like-behaviour and impairs social novelty preference whereas sociability is unaffected. On the other hand, re-socialization can revert both isolation-induced anxiety and social memory impairment. However, OXT and its signalling remained reduced in the abovementioned brain areas, suggesting that the observed changes in OXT-Ca2+ pathway proteins were permanent in male and female degus. Based on these findings, we conclude degus experience social stress differently, suggesting the existence of sex-related mechanisms to cope with specific adaptive challenges.Modulation of cognitive control by emotion and motivation has become a major topic in cognition research; however, characterizing the extent to which these influences may dissociate has proved challenging. Here, I examine recent advances in this literature, focusing on (1) neuromodulator mechanisms underlying positive affect and reward motivation effects on cognitive control; (2) contingency and associative learning in interactions between affect/reward and cognitive control; (3) aspects of task design, unrelated to affect/reward, that may have acted as confounding influences on cognitive control in prior work. I suggest that positive affect and reward should not be considered singular in their effects on cognitive control, but instead varying on multiple parameters and interacting with task demands, to determine goal-directed, adaptive behavior.Ectopic pancreas is asymptomatic and mostly found in the stomach and proximal small bowel. It is difficult to distinguish ectopic pancreas with other submucosal tumors of the gastrointestinal (GI) tract on computed tomography (CT) without histological confirmation. We encountered a case of ectopic pancreas coexisting with submucosal lipoma in the distal jejunum which was misdiagnosed as fat-containing submucosal tumor. We report the CT findings and review previously reported cases of ectopic pancreas coexisting with submucosal lipoma. The knowledge that ectopic pancreas can occur with benign lipoma, and its imaging features would be helpful for the diagnosis and management of patients.Posterior reversible encephalopathy syndrome (PRES) is a rare potential immune-related adverse event (irAE) of checkpoint inhibitors. PRES is a disorder that has a variety of clinical and radiological features, which makes it a challenge for advanced practice registered nurses to diagnose. IrAEs such as PRES require prompt recognition and intervention to optimize clinical outcomes. This study aimed to ascertain levels of distress and contributing factors among parent caregivers of pediatric cancer patients in Singapore. In this descriptive correlational study, parental caregivers were recruited via convenience sampling during their child's inpatient admission or outpatient appointment. They were asked to complete a self-administered demographic survey and the Distress Thermometer for Parents (DT-P) tool. Descriptive statistics, Chi-square tests, and correlation analyses were performed. The mean DT-P score was 5.07 (standard deviation = 2.78), out of a maximum of 10. Distress was reported among 67.9% ( = 55) of caregivers. The cognitive domain of caregiving problems on the DT-P was found to correlate with distress. Parents most frequently reported cognitive problems ( = 21, 25.9%) and, least often, social problems ( = 6, 7.4%). Practical ( = 0.040), emotional ( = 0.001), physical ( = 0.026), and cognitive problems ( = 0.001) of caregiving were statistically significantly associated with distress.
