Background With approximately one pathologist for one million people compared to ratios of approximately 1 to 25 000 in the United States and United Kingdom, there is a severe shortage of pathologists in much of Africa. The situation is particularly severe in Zambia, where, in 2009, the ratio was 1 to 1.4 million. Objective To address this, a postgraduate Master of Medicine (MMed) training programme was launched in Lusaka in 2011. Methods The process and most significant challenges and lessons learned were documented, as they may be of value to other countries facing similar challenges. Results Since 2011, four Zambian pathologists have graduated, doubling the number of indigenous pathologists in the country. Currently 10 students are in training. The most significant problem was issues arising from the split responsibilities of the Ministries of Health and of Education and the most important lesson learned was the crucial need for broad local ownership and commitment. Conclusion Successfully addressing the shortage of local pathologists by creating country-specific, postgraduate MMed training programmes, even in situations of restricted resources, is feasible. However, having access to and support from the shared resources, expertise and knowledge of a regional College of Pathologists would be a major advantage.Background The coronavirus 2019 (COVID-19) pandemic has posed unique challenges in healthcare. In obstetrics, there is little information available to guide practice. As new data emerge, the spectrum of initial presenting symptoms has expanded from fever, cough, and dyspnea to gastrointestinal and other symptoms in both pregnant and non-pregnant patients. Case A 36-year-old woman, G4P2, at 33 weeks of gestation presented very early in the COVID-19 course with four days of cough and fever, without recent travel or known exposure. She appeared well, with stable vital signs, and was sent home to self-quarantine after a specimen for COVID-19 testing was collected. Two days later, she presented with nausea, vomiting, and abdominal pain, and was diagnosed with acute pancreatitis. Conclusion To date, no cases of human pancreatitis have been identified as related to a COVID-19 infection, although multiple other gastrointestinal symptoms have been described. Given the lack of other etiology, we consider the possibility that patient's acute pancreatitis could be secondary to COVID-19 infection.Background Trends in contact with a high volume national digital mental health service (DMHS), the MindSpot Clinic, provide a unique opportunity to assess the mental health effects of the COVID-19 pandemic. Methods Three methods were used to assess changes in responses to COVID-19. First, website visits and call centre traffic were compared across two time periods the "comparison period" (1 to 28 September 2019), and during the early weeks of the "COVID-19 pandemic" (19 March to 15 April 2020). Second, demographic and symptom data were compared across all patients who started an assessment during the comparison (n = 1650) and the COVID-19 period (n = 1668). Third, responses to questions about the impact of COVID-19 introduced to the assessment from 19 March 2020, and reports from treating therapists were examined. Results There was an 89% increase in website visits and a 90% increase in telephone calls to the clinic in the early COVID-19 period compared to the comparison period. There was a higher proportion and monitoring the mental health of the population.[This corrects the article DOI 10.1002/advs.201800760.].Recently, metal halide perovskite light-emitting diodes (Pero-LEDs) have achieved significant improvement in device performance, especially for external quantum efficiency (EQE). And EQE is mostly determined by internal quantum efficiency of the emitting material, charge injection balancing factor (ηc), and light extraction efficiency (LEE) of the device. Herein, an ultrathin poly(3,4-ethylenedioxythiophene)poly(styrene sulfonate) (UT-PEDOTPSS) hole transporter layer is prepared by a water stripping method, and the UT-PEDOTPSS can enhance ηc and LEE simultaneously in Pero-LEDs, mostly due to the improved carrier mobility, more matched energy level alignment, and reduced photon loss. More importantly, the performance enhancement from UT-PEDOTPSS is quite universal and applicable in different kinds of Pero-LEDs. https://www.selleckchem.com/products/k-ras-g12c-inhibitor-12.html As a result, the EQEs of Pero-LEDs based on 3D, quasi-3D, and quasi-2D perovskites obtain enhancements of 42%, 87%, and 111%, and the corresponding maximum EQE reaches 17.6%, 15.0%, and 6.8%, respectively.Cancer stem cells (CSCs) are rare cancer cells that are postulated to be responsible for cancer relapse and metastasis. However, CSCs are difficult to isolate and poorly understood. Here, a bioinspired approach for label-free isolation and culture of CSCs, by microencapsulating one cancer cell in the nanoliter-scale hydrogel core of each prehatching embryo-like core-shell microcapsule, is reported. Only a small percentage of the individually microencapsulated cancer cells can proliferate into a cell colony. Gene and protein expression analyses indicate high stemness of the cells in the colonies. Importantly, the colony cells are capable of cross-tissue multilineage (e.g., endothelial, cardiac, neural, and osteogenic) differentiation, which is not observed for "CSCs" isolated using other contemporary approaches. Further studies demonstrate the colony cells are highly tumorigenic, metastatic, and drug resistant. These data show the colony cells obtained with the bioinspired one-cell-culture approach are truly CSCs. Significantly, multiple pathways are identified to upregulate in the CSCs and enrichment of genes related to the pathways is correlated with significantly decreased survival of breast cancer patients. Collectively, this study may provide a valuable method for isolating and culturing CSCs, to facilitate the understanding of cancer biology and etiology and the development of effective CSC-targeted cancer therapies.Radioluminescent materials (scintillators) are widely applied in medical imaging, nondestructive testing, security inspection, nuclear and radiation industries, and scientific research. Recently, all-inorganic lead halide perovskite nanocrystal (NC) scintillators have attracted great attention due to their facile solution processability and ultrasensitive X-ray detection, which allows for large area and flexible X-ray imaging. However, the light yield of these perovskite NCs is relatively low because of the strong self-absorption that reduces the light out-coupling efficiency. Here, NCs with self-trapped excitons emission are demonstrated to be sensitive, reabsorption-free scintillators. Highly luminescent and stable Cs3Cu2I5 NCs with a photoluminescence quantum yields of 73.7%, which is a new record for blue emission lead-free perovskite or perovskite-like NCs, is produced with the assistance of InI3. The PL peak of the Cs3Cu2I5 NCs locates at 445 nm that matches with the response peak of a silicon photomultiplier.

In multivariate analysis, age was an independent risk factor of MCI aggravating, while attention (MoCA) was independent protective factor for MCI progression.Conclusions Age and worsening attention but not depression in MCI patients were independently associated with the progression of dementia in a 6-year follow-up period.As a by-product during flour production, wheat bran is mainly used as raw material for fodder or fermentation. In the present work, wheat bran was extruded with different moisture conditions and the consequently chemical component, absorption capacity, and antioxidant activity of treated wheat bran were analyzed. Results showed that extrusion decreased the particle size and crystallinity of wheat bran, but increased the soluble dietary fiber content of which from 3.08% to 11.78%. Meanwhile, water holding capacity, oil holding capacity for peanut oil and lard, and swelling capacity of WB-W-G-Na reached 5.67 g/g, 3.34 g/g, 3.58 g/g and 4.3 mL/g, respectively. Moreover, DPPH radical scavenging activity of WB-W-G-Na increased from 6.8% to 18.4% and hydroxyl radical scavenging activity increased from 5.3% to 15.9%. Overall, this work provides an excellent pretreatment method for increasing the functional activities of wheat bran in the food industry.The objective of this study was to assess the prevalence of domestic violence in ever-married women in India and analyze the relationship between domestic violence and use of female sterilization as contraception. We analyzed data from the National Family Health Survey 2005-2006 (NFHS3). The Domestic Violence Module of the survey included abuse experiences and reproductive health outcomes of ever-married women aged 15 to 49 years (n = 69,704). The main outcome of interest was female sterilization and domestic violence experience was the main independent variable. Covariates in our multivariate regression models were guided by the socioecological model for domestic abuse. We estimated a reference linear probability model for the dichotomous outcome. We also employed an instrumental variables procedure to strengthen causal inference under such potential sources of bias as measurement error in reporting domestic violence and omitted variables. The reference model showed an increase of 2.1 percentage points (p less then .001) in the probability of female sterilization associated with exposure to domestic violence. After correcting the estimate for the measurement error and omitted variable bias, we found that domestic violence was associated with an increase in female sterilization by 6.4 percentage points (p less then .001), which is 18% higher than the rate of sterilization among non-victims. In conclusion, our findings imply that domestic violence may lead abuse victims to opt for female sterilization as contraception. Domestic violence is a significant obstacle to efficient contraceptive use. Programs directed toward violence prevention should work conjointly with family planning programs in India.Purpose Cerebral venous sinus stenosis (CVSS) is easily neglected in clinical setting due to its nonspecific symptoms. In patients with cerebral arterial stenosis (CAS), the symptoms caused by CVSS are often mistakenly thought of being attributed to CAS. In this case, we aimed to highlight the clinical manifestations and treatment strategies of CVSS comorbid with CAS.Materials and methods We present an 83-year-old female who complained a series of nonspecific and non-focal neurological deficits such as tinnitus, head noise, dizziness, etc. She was initially diagnosed as CAS and underwent anti-CAS medication orally for over 2 years, whereas her symptoms were still aggravating.Results Magnetic resonance venography (MRV) and magnetic resonance imaging (MRI) displayed severe stenoses at bilateral sigmoid-transverse sinus conjunctions, and thus, the patient underwent intravenous stenting finally. Her aforementioned symptoms significantly attenuated after venous stenting and even disappeared gradually at 3-month, 6-month and 1-year follow-up.Conclusions This paper revealed that cerebral venous outflow disturbance should not be overlooked when the nonspecific and non-focal neurological deficits could not be explained by cerebral artery disease. For this arteriovenous condition, intravenous stenting may be a feasible and effective way for symptoms relieving.Introduction Although several lipid-lowering drugs are available, they are not sufficient for some patients. Bempedoic acid is a small molecule adenosine triphosphate-citrate lyase inhibitor indicated for the treatment of adults with hypercholesterolemia. Areas covered We performed a systematic review of the literature using PubMed database, and the following keywords were used 'bempedoic acid,' 'hypercholesterolemia,' and 'adenosine triphosphate citrate lyase.' The chemical property, mechanism of action, pharmacokinetics, clinical efficacy, and safety of bempedoic acid are introduced in this paper. Expert opinion Bempedoic acid can modulate the metabolism of cholesterol. Clinical trials indicated that bempedoic acid could significantly reduce low-density lipoprotein cholesterol levels. Bempedoic acid was well tolerated.Objective The aim of this study was to determine the effects of activity and cam morphology on cartilage composition during adolescence and investigate the development of cartilage composition with age. Design Cross-sectional observational cohort study of individuals from football club academies and an age-matched control population, aged 9 to 18 years. Assessments included questionnaires and T2-mapping of hips. https://www.selleckchem.com/products/k-ras-g12c-inhibitor-12.html Primary imaging outcome measures were T2 relaxation time of acetabular and femoral cartilage, average alpha angle, and lateral epiphyseal extension. Results The cohort consisted of 109 elite male footballers, 49 male controls, and 51 female controls. Elite male footballers had an acetabular cartilage T2 value 4.85 ms greater than male controls (P less then 0.001). A significant positive correlation existed between Physical Activity Questionnaire Score and acetabular cartilage T2 value (coefficient 1.07, P less then 0.001) and femoral cartilage T2 value (coefficient 0.66, P = 0.032). Individuals with a closed physis had an acetabular cartilage T2 value 7.

Flow diversion of acutely ruptured intracranial aneurysms (IAs) is controversial due to high treatment-related complication rates and a lack of supporting evidence. We present clinical and radiological results of the largest series to date. This is a nationwide retrospective study of acutely ruptured IAs treated with flow diverters (FDs). The primary outcome was the modified Rankin Scale (mRS) score at the last available follow-up time. Secondary outcomes were treatment-related complications and the aneurysm occlusion rate. 110 patients (64 females; mean age 55.7 years; range 12-82 years) with acutely ruptured IAs were treated with FDs between 2012 and 2020 in five centers. 70 acutely ruptured IAs (64%) were located in anterior circulation, and 47 acutely ruptured IAs (43%) were blister-like. A favorable functional outcome (mRS 0-2) was seen in 73% of patients (74/102). Treatment-related complications were seen in 45% of patients (n=49). Rebleeding was observed in 3 patients (3%). The data from radiological follow-ups were available for 80% of patients (n=88), and complete occlusion was seen in 90% of aneurysms (79/88). The data from clinical follow-ups were available for 93% of patients (n=102). The overall mortality rate was 18% (18/102). FD treatment yields high occlusion for acutely ruptured IAs but is associated with a high risk of complications. Considering the high mortality rate of aneurysmal subarachnoid hemorrhage, the prevention of rebleeding is crucial. Thus, FD treatment may be justified as a last resort option. FD treatment yields high occlusion for acutely ruptured IAs but is associated with a high risk of complications. https://www.selleckchem.com/products/pilaralisib-xl147.html Considering the high mortality rate of aneurysmal subarachnoid hemorrhage, the prevention of rebleeding is crucial. Thus, FD treatment may be justified as a last resort option. Approximately one-third of patients with ischemic stroke treated with endovascular treatment do not recover to functional independence despite rapid and successful recanalization. We aimed to quantify the importance of predictors of poor functional outcome despite successful reperfusion. We analyzed patients from the MR CLEAN Registry between March 2014 and November 2017 with successful reperfusion (extended Thrombolysis In Cerebral Infarction ≥2B). First, predictors were selected based on expert opinion and were clustered according to acquisition over time (ie, baseline patient factors, imaging factors, treatment factors, and postprocedural factors). Second, several models were constructed to predict 90-day functional outcome (modified Rankin Scale (mRS)). The relative importance of individual predictors in the most extensive model was expressed by the proportion of unique added χ to the model of that individual predictor. Of 3180 patients, 1913 (60%) had successful reperfusion. Of these 1913 patientessfully reperfused patients with ischemic stroke. This implies that prevention of postprocedural adverse events has the greatest potential to further improve outcomes in these patients. The most common cancer diagnosed in germline pathogenic variant (PV) carriers is premenopausal breast cancer. An increased rate of breast tumour HER2 positivity has been reported in this group. Screening for breast/other cancers is recommended in PV carriers. 1. To assess the frequency of germline PVs reported diagnostically in women with breast cancer at <30 years of age.2. To evaluate the impact of personal/family history and HER2 status on the likelihood of germline pathogenic/likely pathogenic variant (PV/LPV) identification. Genetic test results from patients undergoing diagnostic germline tests between 2012 and 2017 in the four London Regional Clinical Genetics Services were reviewed. Clinical/pathology data and family history were extracted from genetics files for women diagnosed with breast cancer at <30 years. The overall germline PV/LPV variant detection rate was 9/270=3.3% in all women diagnosed with breast cancer at <30 years and 2/171=1.2% in those with no second/subsequent cancer diagnosis or family history of -spectrum cancers. Breast cancers were significantly more likely to be HER2-positive in PV/LPV carriers than in non-carriers (p=0.00006). Germline PVs/LPVs are uncommon among women diagnosed with breast cancer aged <30 years without other relevant personal or family cancer history but have an important clinical impact when identified. Germline TP53 PVs/LPVs are uncommon among women diagnosed with breast cancer aged less then 30 years without other relevant personal or family cancer history but have an important clinical impact when identified. In spring 2020, a novel hyperinflammatory process associated with severe acute respiratory syndrome coronavirus 2 multisystem inflammatory syndrome in children (MIS-C) was described. The long-term impact remains unknown. We report longitudinal outcomes from a New York interdisciplinary follow-up program. All children <21 years of age, admitted to NewYork-Presbyterian with MIS-C in 2020, were included. Children were followed at 1 to 4 weeks, 1 to 4 months, and 4 to 9 months postdischarge. In total, 45 children were admitted with MIS-C. The median time to last follow-up was 5.8 months (interquartile range 1.3-6.7). Of those admitted, 76% required intensive care and 64% required vasopressors and/or inotropes. On admission, patients exhibited significant nonspecific inflammation, generalized lymphopenia, and thrombocytopenia. Soluble interleukin (IL) IL-2R, IL-6, IL-10, IL-17, IL-18, and C-X-C Motif Chemokine Ligand 9 were elevated. A total of 80% ( = 36) had at least mild and 44% ( = 20) had moderate-severe echocardiographic abnormalities including coronary abnormalities (9% had a score of 2-2.5; 7% had a score > 2.5). Whereas most inflammatory markers normalized by 1 to 4 weeks, 32% ( = 11 of 34) exhibited persistent lymphocytosis, with increased double-negative T cells in 96% of assessed patients ( = 23 of 24). By 1 to 4 weeks, only 18% ( = 7 of 39) had mild echocardiographic findings; all had normal coronaries. At 1 to 4 months, the proportion of double-negative T cells remained elevated in 92% (median 9%). At 4 to 9 months, only 1 child had persistent mild dysfunction. One had mild mitral and/or tricuspid regurgitation. Although the majority of children with MIS-C present critically ill, most inflammatory and cardiac manifestations in our cohort resolved rapidly. Although the majority of children with MIS-C present critically ill, most inflammatory and cardiac manifestations in our cohort resolved rapidly.

Background Data regarding the successful ablation site of idiopathic outflow tract (OT) ventricular arrhythmias (VAs) in the modern era of mapping and ablation are limited. Methods and results Over a 4-year period, a total of 309 patients underwent detailed activation mapping of OT VAs including the right ventricular outflow tract (RVOT), the left ventricular outflow tract (LVOT) and the aortic cusps (AC), and the coronary venous system. 244 cases were successfully ablated at the index procedure (78.9%). The successful ablation site was more frequently located at the LVOT/ACs (51.6%) followed by RVOT (36.2%). In particular, the ACs was the predominant successful ablation site of idiopathic OT VAs (46.7%). An epicardial site of origin was predictor of ablation failure (p less then 0.05). Conclusions The ACs is the predominant successful ablation site of idiopathic OT VAs. Take-home message The aortic cusps are the predominant successful ablation site of idiopathic idiopathic outflow tract ventricular arrhythmias.Introduction Primary mouse cardiomyocytes are essential tools for cardiovascular pharmacology research at the cellular and molecular levels, but their low viability and low purity have often caused challenges in previous studies. Hence, we developed an improved two-step method for extraction and purification of primary cardiomyocytes from neonatal mice. Method This method consisted of two steps 1) isolation and pre-digestion of heart tissues from 1- to 3-day-old C57 neonatal mice and 2) extraction and purification of cardiomyocytes. The traditional method of primary mouse cardiomyocyte isolation was used as the control group to assess the extraction efficiency of cardiomyocytes by the two-step method, and the purity and viability of cardiomyocytes were evaluated by immunofluorescence staining and autonomous beating analysis, respectively. Results Compared with the control method, the two-step method enabled acquisition of more cells from mouse hearts (1.28 ± 0.11 × 106vs 0.59 ± 0.15 × 106 cells/heart), and the resulting cells exhibited higher adherence rates and cell purity (93.25 ± 1.69% vs 73.62 ± 9.76%) after 48 h of culture. Moreover, the viability of cardiomyocytes was also evidently higher in the two-step group than in the control group (124.67 ± 10.50 vs 88.50 ± 6.61 beats/min). Discussion Compared with the traditional method, the two-step method exhibited significantly better efficiency in extraction of primary cardiomyocytes and yielded cells with greater purity and viability. The two-step method will likely become a standard method for studies based on primary mouse cardiomyocytes in the future.Objective Evaluate dynamic balance and postural stability in patients with adult spinal deformity (ASD) compared with published age-matched normative data. Methods Eleven patients with ASD were prospectively enrolled. Postural stability was tested using static and dynamic posturography; patients stood on a movable platform with integrated force plate and performed standardized sensory organization testing (SOT), evaluating the influence of sensory processing on postural stability under 6 conditions, and motor control testing, assessing reflexive postural reactions to an external perturbation. Patient performance was compared with that of published age-matched controls. Quality of life metrics included scores on the SRS-22 questionnaire, SF-36, and Morse Fall Scale. Correlations between postural stability and radiographic measurements were performed. Results ASD patients demonstrated significantly lower SOT scores (P≤0.03) in 5 of 6 conditions tested, and greater latency of limb movement during backward translation (P=0.04) compared with controls. Lower SOT scores were associated with a history of falls. ASD patients who self-reported falling in the previous 6 months, when compared to nonfallers, demonstrated significantly lower SOT scores (P=0.04) and significantly lower SRS-22 self-image subscores (P=0.003). Thoracic kyphosis and mediolateral sway (predictor of falls) were positively correlated in the eyes open and eyes closed conditions (P≤0.04). Conclusions ASD patients demonstrated impaired postural stability, diminished sensory integration, and delayed response to external perturbations compared with normal control data. Postural stability and quality of life metrics correlated with self-reported falls. These findings suggest that ASD patients have abnormal postural stability and may be at elevated risk of falls.Objectives To evaluate the morphological characteristics and clinical significance of epidural gas based on computed tomography (CT) and magnetic resonance imaging (MRI) findings and to determine their relationship with radiculopathy. Materials and methods Between March 2009 and November 2018, 110 epidural gas lesions were identified in 103 patients who underwent both CT and MRI for suspected herniated disc in the authors' institution. Patterns of epidural gas were classified as air pseudocyst, air cyst, air-contained disc herniation, and honeycomb-like air cyst. These gas patterns were compared, and possible correlations between these gas patterns and radiculopathy were evaluated. Results Overall agreement between CT and MRI findings for evaluation of all lesions and for differentiation of epidural gases was good (kappa [κ] = 0.775). Air pseudocysts demonstrated a moderate correlation (κ=0.496) and air cysts showed a good correlation (κ=0.661) with radiculopathy on MRI, whereas air-contained disc herniation and honeycomb-like cysts demonstrated a strong correlation (κ=0.810 and 0.927, respectively) with radiculopathy on MRI. Conclusions This study's results help delineate new classifications of epidural gases. https://www.selleckchem.com/products/FK-506-(Tacrolimus).html Additionally, lumbar epidural gas with disc material (e.g., air-contained disc herniation and honeycomb-like cysts) on MRI was associated with radiculopathy.Objective Intraoperative imaging is critical in cerebrovascular surgery to assess the technical success of the operation. This case series aimed to evaluate safety and efficacy of 3-dimensional rotational angiogram (3D-RA) in addition to 2-dimensional intraoperative angiography (2D-IOA) during cerebrovascular surgery in the hybrid operating room. Methods All consecutive patients who underwent open cerebrovascular surgery and intraoperative 2D-IOA with 3D-RA in a hybrid operating room at 2 academic centers between August 2018 to December 2019 were identified from a prospectively maintained institutional database. Medical charts and operative videos including intraoperative angiography were reviewed and clinical and angiographic outcomes assessed. Results A total of 40 cerebrovascular surgeries in 39 patients (mean age 53 ± 13 years; 51% female) were carried out with the addition of 3D-RA to 2D-IOA in the hybrid operating room. Following 3D-RA in addition to 2D-IOA, 1 (2.5%) surgical alteration occurred in an aneurysm clipping.

SO42- and NO3- did not affect the reaction. Overall, this study shows that thermally activated persulphate can effectively remove BP and water matrix anions greatly influence the reaction.Julius Lothar Meyer, John Newlands, and Dmitrii Mendeleev were amongst the discoverers of the periodic system of the elements. Although their systems are similar enough to be recognised as the precursors for the modern periodic system, they were also different. Here, I argue that many of their differences can be explained in terms of how the chemists emphasised different values in the process of developing their systems. In particular, Newland highlighted the simplicity of his arrangements; Meyer was more careful about the quality of data that gave rise to his system of elements; and Mendeleev sought to make his system more complete. By shedding light as to how the values of simplicity, completeness and carefulness guided the development of early periodic systems, this paper contributes to a broader understanding of how values influence science.Fully differentiated HepaRG™ cells are the hepatic cell line of choice for in vitro work in toxicology and drug trials. They are derived from a hepatoblast-like progenitor (HepaRG™-P) that differentiate into a co-culture of hepatocyte-like and cholangiocyte-like cells in the presence of differentiation-inducing chemical dimethylsulfoxide (DMSO). This process requires 2 weeks of proliferation and differentiation and can be time consuming and costly. Identifying a chemical free method to push HepaRG™-Ps towards a mature lineage would save both time and money. It has been shown, that tissue culture substrates play an important role in the development and maturity of a cell line, and this is particularly important for progenitor cells, which retain some form of plasticity. Oxygen plasma treatment is used extensively to modify cell culture substrates, and there is evidence that patterned rather than planar surfaces have a positive effect on proliferation and differentiation. In this study, we compared the effect of standard tissue culture plastic (TCP), oxygen plasma treated (OPC), and nanopatterned surfaces (NPS) on early differentiation and functionality of HepaRG™-P cells. Since NPS were oxygen plasma treated we initially compared the effect of TCP and OPC to enable comparison between all 3 culture surfaces using OPC as control to asses if patterning could further enhance early differentiation and functionality. The results show that cells grown on OPC substrate exhibited earlier differentiation, proliferation and function of HepaRG™-P's compared to TCP in the absence of DMSO. Culturing these cells on OPC with the addition of NPS did not confer any additional advantage. In conclusion, OPC surface appeared to enhance hepatic differentiation and functionality and could replace traditional methods of differentiating HepaRG-P cells into fully differentiated and functional HepaRGs earlier than traditional methods.Early-onset hypertonia is characteristic of developmental neuromotor disorders, including cerebral palsy (CP). The spa transgenic mouse displays early-onset spasticity, abnormal gait, and motor impairments that are remarkably similar to symptoms of human CP. Previously, we showed that spa mice have fewer motor neurons innervating the tibialis anterior (TA). An expanded innervation ratio may result in increased susceptibility to neuromuscular transmission failure (NMTF). We assessed NMTF in an ex vivo TA muscle nerve preparation from spa and wild-type (WT) mice by comparing forces elicited by nerve versus muscle stimulation. TA muscle innervation ratio was assessed by counting the number of muscle fibers and dividing by the number of TA motor neurons. Muscle fiber cross-sectional areas were also assessed in the TA muscle. We observed that NMTF was immediately present in spa mice, increased with repetitive stimulation, and associated with increased innervation ratio. These changes were concomitant with reduced TA muscle fiber cross-sectional area in spa mice compared with WT. Early-onset hypertonia is associated with increased innervation ratio and impaired neuromuscular transmission. https://www.selleckchem.com/products/fadraciclib.html These disturbances may exacerbate the underlying gait abnormalities present in individuals with hypertonia.NEW & NOTEWORTHY Nerve-muscle interaction is poorly understood in the context of early-onset spasticity and hypertonia. In an animal model of early-onset spasticity, spa mice, we found a marked impairment of tibialis anterior neuromuscular transmission. This impairment is associated with an increased innervation ratio (mean number of muscle fibers innervated by a single motor neuron). These disturbances may underlie weakness and gait disturbances observed in individual with developmental hypertonia and spasticity.In the mid-1800s, plantation-produced tea from India came onto the British market. Tea retailers blended this more malty and black tea with the lighter Chinese-grown tea to which consumers had become accustomed. By the turn of the 20th century, blending helped Empire-grown tea supplant Chinese-grown tea on the market. Scholars of tea have shown how British tea companies working in South Asia stoked racialized fears that Chinese tea arrived in Britain in an adulterated state, laden with impurities that included dyes, perfumes and even human sweat. This article describes how concerns about protecting tea leaves from outside adulteration gave way to concerns about the potential digestive threat that lay inside tea leaves themselves. Medical journals linked the increased consumption of Indian teas to a population-wide 'epidemic' of indigestion. The most cited culprits in this epidemic were tannins, chemical compounds that were also thought to give black tea its characteristic bitterness and color. The normalization of black tea consumption among the British public was not just a work of marketing or branding but a work of resolving uncertainty about what tannins were at a material, biophysical level. As this uncertainty was resolved scientifically, tea was materialized not as a singular, unified product but as an active chemical assemblage.

A heterogeneous landscape composed of high, medium, and low burn severity patches within a forest altered by large wildfires provided habitat for different bat species, but water density and range in elevation were more important for predicting bat habitat use than fire severity in this arid landscape. More than one spatial scale, representing local to landscape levels, should be considered in managing habitat for bats. In arid areas, such as the western United States, maintaining reliable water sources is important for bats. Managing these factors at multiple spatial scales will benefit bat species with different wing morphologies, echolocation call types, and habitat selections.PURPOSE To provide a quantitative clinical-regulatory insight into the status of FDA orphan drug designations for compounds intended to treat lysosomal storage disorders (LSDs). METHODS Assessment of the drug pipeline through analysis of the FDA database for orphan drug designations with descriptive and comparative statistics. RESULTS Between 1983 and 2019, 124 orphan drug designations were granted by the FDA for compounds intended to treat 28 lysosomal storage diseases. Orphan drug designations focused on Gaucher disease (N = 16), Pompe disease (N = 16), Fabry disease (N = 10), MPS II (N = 10), MPS I (N = 9), and MPS IIIA (N = 9), and included enzyme replacement therapies, gene therapies, and small molecules, and others. Twenty-three orphan drugs were approved for the treatment of 11 LSDs. Gaucher disease (N = 6), cystinosis (N = 5), Pompe disease (N = 3), and Fabry disease (N = 2) had multiple approvals, CLN2, LAL-D, MPS I, II, IVA, VI, and VII one approval each. This is an increase of nine more approved drugs and four more treatable LSDs (CLN2, MPS VII, LAL-D, and MPS IVA) since 2013. Mean time between orphan drug designation and FDA approval was 89.7 SD 55.00 (range 8-203, N = 23) months. CONCLUSIONS The drug development pipeline for LSDs is growing and evolving, with increased focus on diverse small-molecule targets and gene therapy. CLN2 was the first and only LSD with an approved therapy directly targeted to the brain. Newly approved products included "me-too"-enzymes and innovative compounds such as the first pharmacological chaperone for the treatment of Fabry disease.Objective of this study was to better understand the use of performance data for evidence-based decision-making by managers in hospitals and other healthcare organisations in Europe in 2019. In order to explore why, what and how performance data is collected, reported and used, we conducted a cross-sectional study based on a self-reported online questionnaire and a follow-up interactive workshop. Our study population were participants of a pan-European professional Exchange Programme and their hosts (n = 125), mostly mid-level hospital managers. We found that a substantial amount of performance data is collected and reported, but could be utilised better for decision-making purposes. Motivation to collect and report performance data is equally internal and external, for improvement as well as for accountability purposes. Benchmarking between organisations is recognised as being important but is still underused. A plethora of different data sources are used, but more should be done on conceptualising, collecting, reporting and using patient-reported data. Managers working for privately owned organisations reported greater use of performance data than those working for public ones. Strategic levels of management use performance data more for justifying their decisions, while managers on operational and clinical levels use it more for day-to-day decision-making. Our study showed that, despite the substantial and increasing use of performance data for evidence-based management, there is room and need to further explore and expand its role in strategic decision-making and supporting a shift in healthcare from organisational accountability towards the model of learning organisations.Mollusc shells are produced from calcified skeletons and have excellent mechanical properties. Shell matrix proteins (SMPs) have important functions in shell formation. A 16.6 kDa whirlin-like protein (WLP) with a PDZ domain was identified in the shell of Mytilus coruscus as a novel SMP. In this study, the expression, function, and location of WLP were analysed. The WLP gene was highly expressed and specifically located in the adductor muscle and mantle. The expression of recombinant WLP (rWLP) was associated with morphological change, polymorphic change, binding ability, and crystallization rate inhibition of the calcium carbonate crystals in vitro. In addition, an anti-rWLP antibody was prepared, and the results from immunohistochemistry and immunofluorescence analyses revealed the specific location of the WLP in the mantle, adductor muscle, and myostracum layer of the shell, suggesting multiple functions for WLP in biomineralization, muscle-shell attachment, and muscle attraction. Furthermore, results from a pull-down analysis revealed 10 protein partners of WLP in the shell matrices and a possible network of interacting WLPs in the shell. In addition, in this study, one of the WLP partners, actin, was confirmed to have the ability to bind WLP. These results expand the understanding of the functions of PDZ-domain-containing proteins in biomineralization and provide clues for determining the mechanisms of myostracum formation and muscle-shell attachment.clinicaltrials.gov (NCT02342860).As the outermost organ, the skin can be damaged following injuries such as wounds and bacterial or viral infections, and such damage should be rapidly restored to defend the body against physical, chemical, and microbial assaults. However, the wound healing process can be delayed or prolonged by health conditions, including diabetes mellitus, venous stasis disease, ischemia, and even stress. In this study, we developed a vibrational cell culture model and investigated the effects of mechanical vibrations on human keratinocytes. The HaCaT cells were exposed to vibrations at a frequency of 45 Hz with accelerations of 0.8g for 2 h per day. The applied mechanical vibration did not affect cell viability or cell proliferation. Cell migratory activity did increase following exposure to vibration, but the change was not statistically significant. https://www.selleckchem.com/products/vacuolin-1.html The results of immunostaining (F-actin), western blot (ERK1/2), and RT-qPCR (FGF-2, PDGF-B, HB-EGF, TGF-β1, EGFR, and KGFR) analyses demonstrated that the applied vibration resulted in rearrangement of the cytoskeleton, leading to activation of ERK1/2, one of the MAPK signaling pathways, and upregulation of the gene expression levels of HB-EGF and EGFR.

07±7.58 vs 37.91±7.13, P less then 0.05) and CNFT was significantly higher (0.085±0.042 vs 0.064±0.037 vs 0.039±0.022, P less then 0.05) in patients with recurrent stroke compared to first stroke and healthy controls. CNBD (42.21±24.65 vs 50.46±27.68 vs 87.24±45.85, P less then 0.001) and CNFL (15.66±5.70, P less then 0.001 vs 17.38±5.06, P = 0.003) were equally reduced in patients with first and recurrent stroke compared to controls (22.72±5.14). CONCLUSIONS Corneal confocal microscopy identified greater corneal nerve fibre loss in patients with recurrent stroke compared to patients with first stroke, despite comparable risk factors. Longitudinal studies are required to determine the prognostic utility of corneal nerve fiber loss in identifying patients at risk of recurrent ischemic stroke.Detection of lameness in cats can be very time-consuming and frustrating. Feline studies have shown that the success of treatment can be evaluated by measurement of the ground reaction force (GRF). However, the possibility of multiple limb involvement or the presence of a compensatory mechanism has not been investigated. Furthermore, there has been no research in cats on possible differences in GRFs between those with stifle problems and those with hip problems, as reported in dogs. In this study, we compared temporospatial parameters and GRFs in 20 lame cats after femoral head and neck ostectomy (FHO) or stifle disease to those in 15 healthy cats. An orthopedic examination was performed in all cats and radiographs were obtained to confirm the disease. GRFs, including peak vertical force (PFz), vertical impulse (IFz), time to PFz, and temporospatial parameters, including step length, paw contact area, and stance phase duration, were calculated. We also calculated the symmetry index (SI) in the forelimbs and h weight to the other three legs without favoring either the contralateral or the diagonal limb.BACKGROUND Countries in Sub-Saharan Africa (SSA) have seen rapid increases in injection drug use since 2008. In Uganda, the Global Sate of Harm report and studies conducted by Makerere University Crane Surveys have estimated HIV prevalence among people who inject drugs (PWID) at approximately 17%. The objective of the research was to document injection and other drug-related risks among people who use drugs in Uganda to develop comprehensive HIV/HCV prevention interventions. METHODS Between August and September 2018, we conducted qualitative interviews among male and female people who use drugs. Interview topics included the availability and accessibility of clean syringes, injection risks, overdose, sexual-risk behaviors, and the availability and accessibility of harm reduction and drug treatment services. RESULTS Participants reported several injection-related risks including sharing and reusing syringes, pooling and mixing drugs in the same container, measuring drugs using syringes, getting prefilled injections from dealers, being injected by other people who inject drugs, and using contaminated water or blood to dilute drugs. Participants reported a scarcity of harm reduction services, although a few appear to have participated in the syringe exchange pilot conducted by the Uganda Harm Reduction Network (UHRN). Even fewer reported knowing organizations that helped people who use drugs abstain from or reduce their use. Medication assisted therapy (MAT) and naloxone to reverse overdoses are not currently available. CONCLUSIONS Comprehensive prevention and treatment services are needed in Uganda and should include expanded syringe exchange programs, social network HIV testing, HCV testing, provision of naloxone and MAT, and linkage to and retention in HIV care.BACKGROUND Little is known about differences in the size and morphology of the right and left human tali. The present study demonstrates differences between right and left talar morphometric geometric profiles as fluctuating asymmetry in matched pairs of cadaveric specimens. https://www.selleckchem.com/products/bx471.html METHODS In total, 24 tali were collected in this study. All eligible tali were systematically measured with a Vernier caliper and three-dimensional laser scanner, which provided data for further analysis regarding the talar morphometric geometric profiles. Data were calculated to demonstrate differences between the right and left talar profiles using a matched-pair method, including the general size of the talus. RESULTS The average talar length was 53.5 mm, the average talar dome height was 31.2 mm, and the average talar body width was 41.3 mm. The average anterior trochlear width, middle trochlear width, posterior trochlear width, and trochlear length were 31.8, 31.2, 28.3, and 30.7 mm, respectively. Eleven matched pairs of intact tali were eligible for the matched-pair study. Paired t-tests showed significant differences in the talar dome height (P = 0.019), middle trochlear width (P = 0.027), and posterior trochlear width (P = 0.016) between the right and left tali. However, there were no significant differences in the surface area or volume between the right and left tali. CONCLUSION Significant differences in the morphometric profile were found between the right and left matched pairs of tali. This basic information indicates that the profile of the contralateral talus may not be used as a single reference to reconstruct or duplicate the talus of interest in certain conditions such as talar prosthesis implantation or customized total ankle replacement.BACKGROUND Hepatitis B (HB) is a viral infection that affects the liver and can lead to life-threatening conditions including cirrhosis and liver cancer. Over a billion people are estimated to be infected globally with the hepatitis B virus, with over 240 million chronically infected. Sub-Saharan Africa including Ghana is an HBV endemic area and an estimated 5%- 10% of the population in the region is infected. Research on the knowledge and vaccination status of hepatitis B in rural communities in Ghana is lacking. OBJECTIVES The objectives of this study proposed were to assess the HBV knowledge, risk of HBV infection, and vaccination status of high school students in two rural districts of the Northern region on Ghana. METHODS A cross-sectional study of a random sample of 426 students from two senior high schools in the Nanumba North and South districts of the Northern region of Ghana on hepatitis B knowledge and vaccination status was conducted. Descriptive statistics were used to analyze and present data on demographic and knowledge variables.

Objective This study aimed to evaluate variations in anterior condylar height (ACH) of the distal femur in varus knee osteoarthritis and evaluate the association between ACH and knee flexion. Design Computed tomography (CT) images of 171 knees (143 patients; age 73.7 ± 8.3 years; 132 females, 39 males) with symptomatic primary knee osteoarthritis and varus alignment undergoing primary total knee arthroplasty, unilateral knee arthroplasty, or high tibial osteotomy were evaluated. Several other anatomic parameters were measured on CT or radiography. The ACH and knee flexion correlation was analyzed, and factors contributing to knee flexion were determined using multivariable regression analysis. Results Medial ACH (mean, 8.1 mm; range, -2.8 to 19.9 mm) was smaller (P less then 0.001) but more variable (F = 1.8, P less then 0.001) than lateral ACH (mean, 10.7 mm; range, 3.6-18.3 mm). Medial ACH was moderately correlated with flexion (r = -0.44, 95% confidence interval [CI], -0.55 to -0.32), whereas lateral ACH was weakly correlated (r = -0.38; 95% CI, -0.50 to -0.25). On multivariable linear regression analysis of knee flexion, body mass index (B [partial regression coefficient] = -1.1), patellofemoral Kellgren-Lawrence grade (B = -4.3), medial ACH (B = -1.2), medial posterior condylar offset (B = 1.2), age (B = -0.4), and varus alignment (B = -0.6) remained significant independent variables (adjusted R2 = 0.35). Conclusions Wide variation and anteriorization of the anterior condyle of the distal femur was observed in advanced osteoarthritis, as an independent determinant of limited knee flexion.Presence of blood in colostrum may change the color of breast milk and it is known as "rusty pipe syndrome." It may resolve within days, but it may be a barrier for exclusive breastfeeding. Knowledge of "rusty pipe syndrome" among health professionals is very helpful in the management of breastfeeding initiation.Identifying and distinguishing between abiotic and biotic signatures of organic molecules such as amino acids and fatty acids is key to the search for life on extraterrestrial ocean worlds. Impact ionization mass spectrometers can potentially achieve this by sampling water ice grains formed from ocean water and ejected by moons such as Enceladus and Europa, thereby exploring the habitability of their subsurface oceans in spacecraft flybys. Here, we extend previous high-sensitivity laser-based analog experiments of biomolecules in pure water to investigate the mass spectra of amino acids and fatty acids at simulated abiotic and biotic relative abundances. To account for the complex background matrix expected to emerge from a salty Enceladean ocean that has been in extensive chemical exchange with a carbonaceous rocky core, other organic and inorganic constituents are added to the biosignature mixtures. We find that both amino acids and fatty acids produce sodiated molecular peaks in salty solutions. Under the ignatures.Background The evidence for optimal blood pressure (BP) targets in Asian patients with hypertension is insufficient and controversial. Western guidelines should be used with caution in clinical practice until there is supporting evidence. Objective Systematically synthesize the evidence on the efficacy of achieving the strict 2018 European Society of Cardiology (ESC) guideline BP targets versus standard BP targets in Asian patients. Data sources We searched PubMed, Web of Science, Scopus, the Cochrane Central Register of controlled trials, and additional databases to retrieve relevant Asian studies. Study selection Randomized controlled trials (RCTs) and observational studies that reported clinical endpoints, had a minimal follow-up period of one year and included Asian patients older than 18 years with essential hypertension. https://www.selleckchem.com/products/k-ras-g12c-inhibitor-12.html Data extraction Two investigators independently conducted the study selection with any discrepancies resolved between team members. Data synthesis We selected 15 studies for analysis (4hese data were obtained from only observational studies and the results were not confirmed by RCTs, probably due to insufficient power. Therefore, further high-quality RCTs are crucial. Limitations Use of aggregated data, the subgroup and meta-regression analyses are inconclusive, limited to English language, unable to estimate summary measures for some outcomes, publication bias difficult to assess, and unclear that results could be extrapolated. Registration The protocol registered in PROSPERO (CRD42018115570). Conflict of interest None.Colonic varices are lesser-known in comparison with gastroesophageal varices in a complication associated with liver cirrhosis. The ideal therapeutic intervention for a colonic varix is still unclear. We report a 42 year-old man with 20 years of alcohol use who presented with hematochezia and abdominal distension. The patient was diagnosed with alcoholic liver cirrhosis. The colonoscopy revealed a dilated and tortuous varix in the transverse colon close to the hepatic flexure with oozing blood, a communicating branch and with "red sign", evidence of acute bleeding. Endoscopic band ligation (EBL), the most useful intervention for esophageal varices, was further successfully performed to arrest the bleeding colonic varices. One month after initial treatment, the colonic varices nearly vanished and were replaced by an ulcer. It is extremely rare for colonic varices to be treated with EBL. There is only one similar case in reported literature, but it seems to be safe and effective as an intervention for EBL for acute colonic variceal bleeding. SIMILAR CASES Second case treated by endoscopic band ligation.Objective To prospectively assess the efficacy of GelrinC in the treatment of chondral and osteochondral femoral cartilage lesions using morphological (Magnetic Resonance Observation of Cartilage Repair Tissue [MOCART]) and quantitative (T2-mapping) magnetic resonance imaging (MRI). Design This study was designed as a prospective single-arm, open label, multicenter study. Morphological magnetic resonance imaging (MRI) for MOCART assessment and T2 mapping was performed 1 week and 6, 12, 18, and 24 months after GelrinC implantation. Evaluation of T2 mapping was based on the assessment of global T2 indices (T2 of the repair tissue [RT] divided by T2 of healthy reference cartilage) and zonal variation. Results Fifty-six (20 female) patients were prospectively enrolled. The mean MOCART score significantly increased from baseline to the 24-month follow-up with 88.8 (95% CI, 85.8-91.9; P less then 0.001) for all lesions combined as well as 86.8 (95% CI, 83.0-90.6) for chondral lesions and 94.1 (95% CI, 68.55-100) for osteochondral lesions.

Additionally, the purine and lipid metabolic pathways were involved in ATDH. https://www.selleckchem.com/products/wm-8014.html Conclusion ATDH was involved in bile acids and lipid and purine metabolism. The BAs metabolic pathway involvement in mice was validated in TB patients. The noninvasive metabolomics approach is more systemic than routine toxicity evaluation and can be used to assess compound toxicity and the underlying mechanism.The long-term efficacy and safety of dupilumab has been demonstrated in clinical trials and only in few real-world studies. We conducted an extension analysis from a previous 16-week study on 109 adult patients affected by moderate-to-severe atopic dermatitis treated with dupilumab. Eczema-Area-and-Severity-Index (EASI), itch numerical-rating-score (itch-NRS), Dermatology-Life-Quality-Index (DLQI) scores, drug survival rate and occurrence of adverse events after 24 and 48 weeks of dupilumab treatment were retrospectively collected. Dupilumab demonstrated sustained improvement of disease severity, pruritus, and quality of life in our series with an increasing percentage of patients gaining EASI75 and EASI90 response during the study period. Few patients interrupted treatment resulting in a very high drug survival rate. We also confirmed the favorable safety profile of the drug with absence of serious adverse events and serious infections throughout the 48-week period. The prevalence of conjunctivitis was low and mainly occurred in the mid-term with resolution of the majority of cases at 48 weeks.Cytoplasmic dynein-1 (hereafter dynein) is a six-subunit motor complex that transports a variety of cellular components and pathogens along microtubules. Dynein's cellular functions are only partially understood, and potent and specific small-molecule inhibitors and activators of this motor would be valuable for addressing this issue. It has also been hypothesized that an inhibitor of dynein-based transport could be used in antiviral or antimitotic therapy, whereas an activator could alleviate age-related neurodegenerative diseases by enhancing microtubule-based transport in axons. Here, we present the first high-throughput screening (HTS) assay capable of identifying both activators and inhibitors of dynein-based transport. This project is also the first collaborative screening report from the Medical Research Council and AstraZeneca agreement to form the UK Centre for Lead Discovery. A cellular imaging assay was used, involving chemically controlled recruitment of activated dynein complexes to peroxisomes. Such a system has the potential to identify molecules that affect multiple aspects of dynein biology in vivo. Following optimization of key parameters, the assay was developed in a 384-well format with semiautomated liquid handling and image acquisition. Testing of more than 500,000 compounds identified both inhibitors and activators of dynein-based transport in multiple chemical series. Additional analysis indicated that many of the identified compounds do not affect the integrity of the microtubule cytoskeleton and are therefore candidates to directly target the transport machinery.The poly(ADP-ribose) polymerase 1 (PARP-1) enzyme has received much attention in the last decade due to its promising role in cancer therapeutics. Despite the expanding use of PARP inhibitors in cancer therapy, little is known about PARP-1 tissue distribution. Our study provides a detailed survey of PARP-1 tissue and cellular distribution using well-preserved cynomolgus monkey organs and a well-characterized, highly specific monoclonal PARP-1 antibody. Overall, PARP-1 was detected in most organs, but its distribution was restricted to specific cells within each tissue, suggesting that PARP-1 expression is tightly regulated. The strongest expression was in the pituitary, the ovary, the male adrenal gland, and the thymus. One of the key findings of this study was the stronger expression of PARP-1 in proliferating cells rather than mature cells. This observation not only provides clues to the importance of PARP-1 in processes such as DNA replication and transcription in these cell types, but it also provides the basis for further investigation into the effects of its inhibition in the context of malignancy. Overall, this study greatly expands the current knowledge of PARP-1 tissue expression, enabling the identification of tissues where PARP inhibition may be most efficacious.Background There is a pressing need for new classes of treatment for psychosis. A key therapeutic target for novel compounds is the NMDA receptor, which may be modulated by nitric oxide donors such as sodium nitroprusside (SNP). Recent studies of SNP in patients with psychosis have mixed results, and the drug has to be administered intravenously. Glyceryl trinitrate (GTN) is a well-established cardiovascular medicine that is also a nitric oxide donor, and can be given orally. Aims We explored the safety and potential effects of GTN in unmedicated patients with a first episode of psychosis. Methods This was a single-centre, randomised, double-blind, placebo-controlled trial from December 2016 to April 2019 (ClinicalTrials.gov identifier NCT02906553). Patients received 3 × sprays of GTN or placebo for three consecutive days, and were re-assessed on Days 1, 2, 3 and 7. The primary outcome was cognition (Jumping to Conclusions task), secondary outcomes were symptoms (Positive and Negative Syndrome Scale (PANSS)), verbal memory (Hopkins Verbal Learning task), and mood (Bond-Lader Visual Analogue Scales). Results Nineteen patients were randomised, and 13 participants were included in the analyses. Compared with placebo, GTN was well tolerated, but was not associated with significant effects on cognition, symptoms, or mood. Bayesian statistics indicate that our results were 2× more likely under the null hypothesis than the alternative hypothesis, providing anecdotal evidence that GTN does not improve psychotic symptoms. Conclusions We found no indication of an effect of GTN on symptoms of psychosis or cognition.The number of cases of aggressive prostate cancer is increasing. Differentiating between aggressive and indolent cases has resulted in increased difficulty for the physician and patient to decide on the best treatment option. Due to this challenge, efforts are underway to profile genetic risk for prostate cancer aggressiveness, which may help physicians and patients at risk for developing aggressive prostate cancer to select an appropriate treatment option. This study explores patients' interest in receiving genetic results, preference for how genetic risk information should be communicated, and willingness to share results with adult male first-degree relatives (FDRs). A nine-item survey was adapted to assess their beliefs and attitudes about genetic testing for prostate cancer aggressiveness. In addition, participants (n = 50) responded to hypothetical scenarios and questions associated with perceived importance of risk disclosure, preferences for receiving genetic risk information, and sharing of results with FDRs.
