Results The providers' overall average score was 50.6% on the SEGUE communication tasks. They did well in 'Set the stage' (54.4%) and 'Elicit information' (56.2%) but performed poorly in 'End the encounter' (24.5%) and 'Understand the patient's perspective' (44.0%). Female and younger providers scored 0.75 (P less then 0.05) and 0.04 (P less then 0.01) points higher than their male and older counterparts on total SEGUE score, respectively. Conclusion Providers in rural China had relatively poor communication skills overall, especially in terms of their demonstration of care for patients and inviting them to participate in the interaction. Gender and age were significantly associated with providers' level of communication skills in rural China.Background We investigated the incidence and causes of sight-threatening diabetes-related eye disease in children living with diabetes in the UK, to inform the national eye screening programme and enable monitoring of trends. Methods We undertook a prospective active national surveillance via the British Ophthalmic Surveillance Unit. Eligible cases were children aged 18 years or younger, with type 1 or 2 diabetes, newly diagnosed between January 2015 and February 2017 with sight-threatening diabetic eye disease. Results Eight children were reported. The annual incidence of all sight-threatening diabetes-related eye disease requiring referral to an ophthalmologist among children living with diabetes (n=8) in the UK was 1.21 per 10 000 person-years (95% CI 0.52 to 2.39) and was largely attributable to cataract (n=5) 0.76 per 10 000 person-years (95% CI 0.25 to 1.77). The incidence of sight-threatening diabetic retinopathy (n=3) among those eligible for screening (12 to 18 year-olds living with diabetes) was 1.18 per 10 000 person-years (95% CI 0.24 to 3.46). No subjects eligible for certification as visually impaired or blind were reported. Conclusions Secondary prevention of visual disability due to retinopathy is currently the sole purpose of national eye screening programmes globally. However, the rarity of treatment-requiring retinopathy in children/young people living with diabetes, alongside growing concerns about suboptimal screening uptake, merit new consideration of the utility of screening for primary prevention of diabetes-related morbidity by using the screening event and findings as a catalyst for better diabetes self-management.'Photopsia' describes the symptom of visual disturbances that are typically flash-like, sudden in onset and brief, and occurring without light entering the eye. Patients reporting photopsia often pose a diagnostic challenge, given the wide range of possible neurological and ophthalmological causes. We review the common causes of photopsia, discuss the assessment and workup of this symptom, and stress the importance of close interdisciplinary liaison to help with its diagnosis and management. We discuss a patient with acute zonal occult outer retinopathy to illustrate these points.Objective The microbiome contributes to the pathogenesis of inflammatory bowel disease (IBD) but the relative contribution of different lifestyle and environmental factors to the compositional variability of the gut microbiota is unclear. Design Here, we rank the size effect of disease activity, medications, diet and geographic location of the faecal microbiota composition (16S rRNA gene sequencing) in patients with Crohn's disease (CD; n=303), ulcerative colitis (UC; n = 228) and controls (n=161), followed longitudinally (at three time points with 16 weeks intervals). Results Reduced microbiota diversity but increased variability was confirmed in CD and UC compared with controls. Significant compositional differences between diseases, particularly CD, and controls were evident. Longitudinal analyses revealed reduced temporal microbiota stability in IBD, particularly in patients with changes in disease activity. Machine learning separated disease from controls, and active from inactive disease, when consecutive time points were modelled. Geographic location accounted for most of the microbiota variance, second to the presence or absence of CD, followed by history of surgical resection, alcohol consumption and UC diagnosis, medications and diet with most (90.3%) of the compositional variance stochastic or unexplained. Conclusion The popular concept of precision medicine and rational design of any therapeutic manipulation of the microbiota will have to contend not only with the heterogeneity of the host response, but also with widely differing lifestyles and with much variance still unaccounted for.Recent work has begun to investigate the role of protein damage in cell death due to ionizing radiation (IR) exposure, but none have been performed on a proteome-wide basis, nor have they utilized mass spectrometry (MS) to determine chemical identity of the amino acid side chain alteration. Here, we use Escherichia coli to perform the first MS analysis of IR-treated intact cells on a proteome scale. From quintuplicate IR-treated (1,000 Gy) and untreated replicates, we successfully quantified 13,262 peptides mapping to 1,938 unique proteins. Statistically significant, but low in magnitude ( less then 2-fold), IR- induced changes in peptide abundance were observed in 12% of all peptides detected, although oxidative alterations were rare. Hydroxylation (+15.99 Da) was the most prevalent covalent adduct detected. https://www.selleckchem.com/products/cynarin.html In parallel with these studies on E. coli, identical experiments with the IR-resistant bacterium, Deinococcus radiodurans, revealed orders of magnitude less effect of IR on the proteome. In E. coli, the most significant target of IR by a wide margin was glyceraldehyde 3'-phosphate dehydrogenase (GAPDH), in which the thiol side chain of the catalytic Cys residue was oxidized to sulfonic acid. The same modification was detected in IR-treated human breast carcinoma cells. Sensitivity of GAPDH to reactive oxygen species (ROS) has been described previously in microbes and here, we present GAPDH as an immediate, primary target of IR-induced oxidation across all domains of life.Tumor endothelial cells (TEC) lining tumor blood vessels actively contribute to tumor progression and metastasis. In addition to tumor cells, TEC may develop drug resistance during cancer treatment, allowing the tumor cells to survive chemotherapy and metastasize. We previously reported that TECs resist paclitaxel treatment via upregulation of ABCB1. However, whether TEC phenotypes are altered by anticancer drugs remains to be clarified. Here, we show that ABCB1 expression increases after chemotherapy in urothelial carcinoma cases. The ratio of ABCB1-positive TEC before and after first-line chemotherapy in urothelial carcinoma tissues (n = 66) was analyzed by ABCB1 and CD31 immunostaining. In 42 cases (64%), this ratio increased after first-line chemotherapy. Chemotherapy elevated ABCB1 expression in endothelial cells by increasing tumor IL8 secretion. In clinical cases, ABCB1 expression in TEC correlated with IL8 expression in tumor cells after first-line chemotherapy, leading to poor prognosis. In vivo, the ABCB1 inhibitor combined with paclitaxel reduced tumor growth and metastasis compared with paclitaxel alone.

We report a new "switched-suppression" effect for conditionals with negated components, for example, "if she had not watered the plants they would not have bloomed" modus tollens is suppressed by alternatives and denial of the antecedent by additional conditions, rather than vice versa (Experiments 3a and 3b). We discuss the implications of the results for alternative theories of conditional reasoning. © 2020 Cognitive Science Society, Inc.OBJECTIVES Age-related hearing loss (ARHL) is a prevalent condition associated with increased risk for depression and cognitive decline. This 12-week prospective, double-blind pilot randomized controlled trial (RCT) of hearing aids (HAs) for depressed older adults with ARHL evaluated the feasibility of a novel research design. METHODS/DESIGN N = 13 individuals aged ≥60 years with Major Depressive Disorder or Persistent Depressive Disorder and at least mild hearing loss (pure tone average ≥ 30 dB) were randomized to receive full- (active) vs low-amplification (sham) HAs added to psychiatric treatment as usual. Duration of HA use in hours/day, adverse events frequency, attrition rate, and maintenance of the study blinding were the primary outcome measures. RESULTS Compliance with HAs was excellent (>9 hours/day for both groups) and rates of adverse events and drop-outs did not differ between groups. Preliminary data demonstrated differential improvement for active vs sham HAs on hearing functioning (Hearing Handicap Inventory for the Elderly [nonparametric effect size (np-ES) = 0.62]), depressive symptoms (Inventory for Depressive Symptomatology [np-ES = 0.31]), cognition (Repeatable Battery for the Assessment of Neuropsychological Status Immediate Memory [np-ES = 0.25]), and general functioning (World Health Organization Disability Assessment Schedule [np-ES = 0.53]). Significantly greater than 50% of both groups correctly guessed their treatment assignment, indicating incomplete concealment of treatment allocation. CONCLUSIONS This pilot RCT for ARHL and late-life depression was feasible to execute and showed clinical promise, but improved methods of blinding the experimental treatments are needed. Larger studies should investigate whether hearing remediation may be an effective preventative and/or therapeutic strategy for late-life depression and cognitive decline. © 2020 John Wiley & Sons Ltd.The structural poses of ligands that bind weakly to protein receptors are challenging to define. In this work we have studied ligand interactions with the adrenoreceptor (AR) subtypes, α 1A -AR and α 1B -AR which belong to the G-protein coupled receptor (GPCR) superfamily by employing the solution-based ligand-observed NMR method INPHARMA (Interligand Noes for PHARmacophore Mapping). Lack of receptor crystal structures and of subtype-selective drugs has hindered the definition of the physiological roles of each subtype and limited drug development. We determined the binding pose of the weak binding α 1A -AR selective agonist, A-61603, relative to an endogenous agonist, epinephrine, at both α 1A -AR and α 1B -AR. The NMR experimental data were quantitatively compared, using SpINPHARMA, to the back-calculated spectra based on ligand poses obtained from all-atom molecular dynamics simulations. The results helped mechanistically explain the selectivity of ( R )-A-61603 towards α 1A -AR, demonstrating an approach for targeting subtype selectivity in ARs. © 2020 WILEY-VCH Verlag GmbH & Co.

Environmental or genetic disruption of circadian rhythms increases the risk of several types of cancer, but the underlying mechanisms are not well understood. Here, we discuss evidence connecting circadian rhythms - with emphasis on the cryptochrome proteins (CRY1/2) - to cancer through in vivo models, mechanisms involving known tumor suppressors and oncogenes, chemotherapeutic efficacy, and human cancer risk.

The aim of this study is to assess the diagnostic value of FC to predict endoscopic response. METHODS Patients with active endoscopic disease at baseline were included. Endoscopies and FC tests were performed at baseline and week 16. Patients with a confirmed endoscopic response at week 16, continued VDZ maintenance therapy and endoscopy and FC tests were performed at week 52. Endoscopic response was defined as endoscopic Mayo score reduction of ≥1, SES-CD of ≥50% or Rutgeerts of ≥1. Correlations were assessed using Spearman and receiver operating characteristic statistics. RESULTS A total of 114; 46 ulcerative colitis and 68 Crohn's disease patients (44 males, median age 40 years) were included after start of VDZ; 85% was anti-TNFα refractory. Endoscopic response was observed in 60 (53%) patients at week 16, the response sustained in 73% at week 52. FC decreased significantly from 819 at baseline to 154 μg/g at week 16. FC at week 16 and 52 were significantly correlated to (sustained) endoscopic response (r-0.62/r-0.67,p400μg/g after induction indicates endoscopic loss of response. This simple FC algorithm may guide clinical decisions on the continuation and optimization of VDZ in IBD patients. This article is protected by copyright.

This rapid and unexpected change of circumstances and loss of structure left many students socially isolated and struggling to cope with massive uncertainty. This article is protected by copyright.

Results Among 162.7 million visits in which patients were taking opioid medication(s), substance use counseling was provided in 2.4%. During visits for patients receiving opioid(s) plus GABAergic(s), substance use counseling was marginally more common (3.1% versus 2.0%, P less then .0001). Substance use counseling was also more common among visits for patients taking opioid(s) with SUD (18.9% versus 1.5%, P less then .0001). Among visits in which a patient was diagnosed with SUD and taking opioid(s) plus GABAergic(s), counseling was more common (23.1% versus 1.4%, P less then .0001) compared to patients taking opioid(s) plus GABAergic(s) without SUD. Conclusions Among national ambulatory care visits in the United States, substance use counseling is provided infrequently for patients taking opioids, even when significant risk factors are present. Increasing patient education may help reduce opioid-related overdose mortality.Arterial stiffness is a good predictor of cardiovascular events. As a substitute for elastic modulus representing stiffness, pulse wave velocity (PWV) has been used for over a century as it is easy to measure; however, PWV is known to essentially depend on blood pressure at the time of measurement. The cardio-ankle vascular index (CAVI) is a relatively new index of global arterial stiffness of the origin of the aorta to the ankle arteries. The characteristic feature is its independency from blood pressure at the measuring time. Recently, a variant index CAVI0 was proposed, which was claimed to be a more accurate arterial stiffness index than CAVI, considering independency from blood pressure. The purpose of this review is to evaluate the properties of CAVI more precisely by comparing with CAVI0, and to confirm the true meaning of CAVI as an index of arterial stiffness. First, the properties of PWV depending on the blood pressure and the variation of PWV values in the cardiac cycle were analyzed. Then, we attempted to clarify the point at which the PWV, adopted in CAVI or in CAVI0, was measured in cardiac cycle. A comprehensive comparison of the clinical data of CAVI and CAVI0 showed that CAVI is more appropriate than CAVI0. In conclusion, CAVI is reconfirmed to be a reliable and useful index of blood pressure-independent arterial stiffness composed of both organic and functional stiffness.Objective Treatment of brain arteriovenous malformations (AVMs) aims to abolish any risk for intracranial hemorrhage with the preservation of the patient's functional status. We present the technique of pre-surgical endovascular devascularization through proximal feeder artery occlusion for the treatment of cranial AVMs rather than nidus occlusion. Also, we highlight the advantages and the possible clinical indications. Patients and methods Two patients with brain AVM and one patient with scalp AVM were treated by pre-surgical endovascular devascularization followed by surgical resection. Endovascular devascularization was performed by occlusion of the AVM feeders only with Liquid Embolic System Agent (Onyx®) 18 without entering and filling the nidus. During surgery, feeding arteries colored with the black color of the Liquid Embolic System Agent were clearly identified and cut. Dissection of the AVM was performed, and resection of the nidus was achieved. Results Total resection of the AVM was achieved in all cases confirmed with follow-up angiographies, with no neurologic or systemic complications. Also, no major bleeding was detected. In addition, the surgical clips were avoided during surgery. Brain AVMs were safely resected in piecemeal fashion. https://www.selleckchem.com/products/wz-811.html Conclusion Pre-surgical endovascular proximal feeder artery devascularization technique shows to be a safe, simple and effective technique for the management of cranial arteriovenous malformations. This technique simplifies both the endovascular and surgical approaches to complicated cranial AVM cases.Background The association between homocysteine and cardiovascular diseases (CVD) and all-cause death was inconclusive. A community-based prospective cohort study was carried out in Beijing to evaluate this association in elderly population for more effective clinical prediction and primary prevention of CVD. Patients and methods Participants were randomly selected from Beijing, China. Questionnaire survey, physical examinations, and laboratory tests were carried out to collect baseline information and investigate clinical characteristics. Each participant was predetermined to be followed by 5 years. CVD events and death were collected as primary variables. A Cox regression analysis was performed to assess the risk of CVD events, CVD death, and all-cause death contributed by homocysteine as well as some other risk factors. Results A total of 1257 participants with an average age of 69.16 years were enrolled in this study. After adjusting for confounders, the hazard ratios (HRs) and 95% confidence intervals ofassociated with CVD events and all-cause death in elderly population without a history of ischemia or congestive heart failure (CHF). The positive association was pronounced among males.Emicizumab, a humanized, bi-specific, monoclonal antibody subcutaneously administered, mimicking the function of FVIIIa, represents a milestone in treatment of patients affected by hemophilia A complicated with inhibitors. The HAVEN 1 and 2 studies have clearly established its superiority compared to bypassing agents for routine prophylaxis in preventing or reducing bleeding episodes in adult and pediatric patients with inhibitors. However, its protection against bleeding is only partial, and concomitant use of a bypassing agent may be required with potential prothrombotic risk. The emicizumab Phase III trials (HAVEN 1, 2 and 4) have shown that the traditional bypassing agents, activated prothrombin complex concentrates or recombinant activated factor VII (rFVIIa), may be necessary for the treatment of breakthrough bleeds or surgery management. A post hoc analysis in particular has shown that the concomitant use of emicizumab and rFVIIa is safe and no thrombotic events have been described. The review describes the state of the art of the concomitant use of emicizumab and rFVIIa for treating acute bleeding and surgeries, its efficacy and safety and the lack of thrombotic events associated with this treatment modality.

Results show a range of deposit volumes that run from 4900 m3 to 59,300 m3. The density of LiDAR point cloud (1 point/m2) ensures metric precision for the superficial layer. The Electrical Resistivity Tomography revealed the geometry of the deposits that superposes two layers marking the border between waste and natural terrain, and the boreholes guarantee the exactness of the waste layer thickness. This synergistic combination of Electrical Resistivity Tomography with LiDAR point cloud yields an accurate method that we used to calculate the volume of waste present in the deposits. Novel wastewater treatment plants (WWTPs) are expected to be less energetically demanding than conventional ones. However, scarce information is available about the fate of organic micropollutants (OMPs) in these novel configurations. Therefore, the objective of this work is to assess the fate of OMPs in three novel WWTP configurations by using a plant-wide simulation that integrates multiple units. The difference among the three configurations is the organic carbon preconcentration technology chemically enhanced primary treatment (CEPT), high-rate activated sludge (HRAS) combined or not with a rotating belt filter (RBF); followed by a partial-nitritation (PN-AMX) unit. The simulation results show that the three selected novel configurations lead mainly to comparable OMPs removal efficiencies from wastewater, which were similar or lower, depending on the OMP, than those obtained in conventional WWTPs. However, the presence of hydrophobic OMPs in the digested sludge noticeably differs among the three configurations. Whereas the configuration based on sole HRAS to recover organic carbon leads to a lower presence of OMPs in digested sludge than the conventional WWTP, in the other two novel configurations this presence is noticeable higher. In conclusion, novel WWTP configurations do not improve the OMPs elimination from wastewater achieved in conventional ones, but the HRAS-based WWTP configuration leads to the lowest presence in digested sludge so it becomes the most efficient alternative. V.Crops that grow on soils with higher fertility often have higher yields and higher tissue nutrient concentrations. Whether this is the case for all crops, and which soil and management factors, or combinations mostly affect yields and food nutrient concentrations however, is poorly understood. Here, the main aim was to evaluate effects of soil and management factors on crop yields and food nutrient concentrations in (i) grain, fruit and tuber crops, and (ii) between high and low soil fertility areas. Total elemental concentrations of Mg, P, S, K, Ca, Fe, Zn, Mn and Cu were measured using a portable X-Ray Fluorescence Spectrometer (pXRF) in maize grain (Zea mays; Teso South, Kenya n = 31; Kapchorwa, Uganda n = 30), cassava tuber (Manihot esculenta; Teso South n = 27), and matooke fruit (Musa acuminata; Kapchorwa, n = 54). Soil properties measured were eCEC, total N and C, pH, texture, and total elemental content. Farm management variables (fertilisation, distance to household, and crop diversity) were collected. Canonical Correspondence Analyses (CCA) with permutation rank tests identified driving factors of alterations in nutrient concentrations. Maize grain had higher correlations with soil factors (CCA > 80%), than cassava tuber (76%) or matooke fruit (39%). In contrast, corresponding correlations to management factors were much lower (8-39%). The main soil properties affecting food nutrients were organic matter and texture. Surprisingly, pH did not play an important role. A positive association of crop diversity with nutrient concentration and yield in lower fertility areas was observed. Considering, food nutrient composition, apart from yield, as response variables in agronomic trials (e.g. fertilisation or soil improvement strategies), would contribute towards discounting the notion that crops growing on fertile soils always produce healthy and high quality foods. Two years of SO2 measurements at El Arenosillo observatory located in the Gulf of Cadiz (Atlantic Ocean) were investigated. Annual hourly averages of 1.9 ± 1.5 μg m-3 and p95 between 3 and 4.4 μg m-3 were recorded, showing clean and background environments. Monthly means vary between 1.5 and 2.4 μg m-3, a monthly evolution was not found. https://www.selleckchem.com/peptide/gp91ds-tat.html SO2 fields from the MERRA2 model were used to identify SO2 sources and its transport, which could be affecting the studied region. Although SO2 records were low, major conductive for SO2 increases were observed in specific periods. A selection methodology was applied to extract these events, which showed a mean of ~11 μg m-3. Surface meteorological observations and ERA5 meteorological fields from the ECMWF model were used to assess the weather conditions. SO2 increases, in cold months occurred under conditions governed by synoptic-scale. Two types of transport scenarios were identified SO2 transport defined as direct impact, which is the sum of the plumes from Portugal and the Huelva area; and indirect impact, where SO2 and sulphate particle emissions from Portugal were transported and accumulated in the Gulf of Cadiz and then carried inland, where new particle formation were observed. Episodes with high SO2 concentrations were also reported in warm periods associated with pure sea-land breezes. The SO2 peaks under sea-land breezes were associated with the transport of SO2 from the south of Portugal to the Gulf of Cadiz, whereas SO2 from the east of the Iberian Peninsula and north of Africa reached the Mediterranean Sea and were then transported to the Atlantic Ocean following the Strait of Gibraltar. Blocking of the airflows from the Mediterranean Sea to the Atlantic Ocean turns the Gulf of Cadiz into a chemical reservoir, where chemical species such as SO2 can accumulate, triggering new particle formation processes. Shifting from a linear to a circular economy in the agrifood domain requires innovative business models, including reverse logistics, new visions on customer-supplier relationships, and new forms of organization and marketing strategies at the crossroads of various value chains. This research aims to identify and characterise different types of business models that create value from agricultural waste and by-products via cascading or closing loops. Conceptual and management insights into circular business models are still sparse. In total, 39 cases have been studied that convert agro-waste and by-products into valuable products via a circular economy approach. Semi-structured interviews and on-site visits of six representative cases have been done, and secondary data been collected. Data has been treated with content analysis. Cases are presented according to the type of organisational structure, resources, transformation processes, value propositions, key partners, customers, strategic approaches and innovation.

emands dominate the practice field at the expense of therapeutic engagement between nurses and clients ultimately affecting client recovery. While nurses' integrity means they desperately try to make space for the therapeutic work, they often become burnt out and disheartened. Implications for practice While nurses are often blamed for failures in the system, the structures that disable nurses in their attempts to practice therapeutically require urgent responses, strengthening professional organizations and engaging in democratic partnerships with consumer groups. © 2020 John Wiley & Sons Ltd.Ryegrass is one of the most important forage crops worldwide. It is the basis for 80% of milk production and 70% of meat production, and has major economic importance. Breeding programs for ryegrass started in the 1920s, and breeders have mainly relied on repeated phenotypic and recently genotypic selection of elite individuals. Although this approach has led to significant improvements in several characters including rust resistance, spring growth, and aftermath heading, it tends to be laborious, expensive and time consuming, mainly due to gametophyte self-incompatibility in most ryegrass species (Sampoux et al., 2011).

Patients transplanted within Milan criteria have outstanding outcomes with a 5- and 10-year survival of 70% and 55%, respectively. Tumor recurrence after transplant is rare in these patients (10%) but treatment options upon recurrence are generally limited and outcomes are poor. There are also several studies showing how a subgroup of patients with tumors outside the Milan criteria might achieve comparable outcomes to patients within Milan criteria. In other words, the size and number of tumor nodules not always reflects tumor biology, which could be better captured using molecular proxis for cancer aggressiveness. Over the last decade, we have significantly improved our understanding of the molecular landscape of early stage HCC. This includes the development of molecular classification, identification of prognostic and mutational signatures, and potential mechanisms of hepatocarcinogenesis. Some of them have already proven useful to predict tumor-related outcomes in HCC patients after LT. Most of these analyses are limited to tissue-derived biomarkers, which limits their implementation in clinical practice as tissue biopsy is not required for HCC diagnosis. Minimally-invasive alternative tools, such as liquid biopsy, are being increasingly explored and could help to individualize risk stratification for patients with HCC who will benefit from LT despite being outside accepted clinical criteria.

The aim of study was to assess the prognostic significance of BRAF V600E mutation in cutaneous melanoma patients. A total of 151 melanomas were included in the study. BRAF V600E mutation was detected using the real-time PCR. https://www.selleckchem.com/products/hth-01-015.html BRAF V600E mutation rate was 51%. BRAF mutation rate was higher for young patients (61.4%) and upper limbs (63.2%), trunk (59.3%) and head and neck (59.2%) were the most frequently afflicted sites in BRAF-mutant patients, whereas lower limbs were mostly affected in BRAF-wild patients (77.8%). Likewise, acral melanomas rarely harbored BRAF mutation (17.1%). The disease-free survivals regarding the entire and Stage III cohorts were longer in the BRAF-mutant group than in the BRAF-wild group (p = .006 and p = .004, respectively), whereas Stage I-II patients had no survival differences between BRAF statuses (p = .2). Likewise, BRAF-mutant patients had better overall survival (OS) time compared to BRAF-wild patients in all stages (p = .01), in Stage III (p = .01), and in Stage IV patients (p = .001). However, no differences between BRAF statuses were observed in Stage I-II melanomas (p = .3). In conclusion, BRAF V600E-mutant melanomas show favorable prognostic impact on both disease-free and OSs in all staged melanomas except local disease. © 2020 Wiley Periodicals, Inc.BACKGROUND Deregulated circulating microRNAs (miRNAs) are potential biomarkers for the early detection and prognosis prediction of non-small-cell lung cancer (NSCLC). The aim of the present study was to investigate the expression pattern of serum exosomal miR-378 in NSCLC and its correlation with clinical variables. METHODS Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was performed to detect serum exosomal miR-378 levels in 103 patients with NSCLC and 60 control subjects. RESULTS Our results showed that serum exosomal miR-378 was significantly overexpressed in NSCLC patients, and serum exosomal miR-378 upregulation was clearly associated with positive lymph node metastasis and advanced TNM stage. In addition, receiver operating characteristic (ROC) analysis demonstrated that combination of serum exosomal miR-378 expression and carcinoembryonic antigen (CEA) had a high discriminating power to differentiate NSCLC subjects from controls. Moreover, serum exosomal miR-378 levels in 73 NSCLC cases were significantly decreased after radiotherapy and could be used as an indicator of radiotherapeutic response in NSCLC. Furthermore, survival analyses revealed that patients with higher serum exosomal miR-378 expression had poor overall survival. Multivariate analysis showed that serum exosomal miR-378 expression was independently associated with overall survival. CONCLUSIONS Collectively, serum exosomal miR-378 has strong potential as a promising non-invasive biomarker for screening and monitoring NSCLC. © 2020 The Authors. Journal of Clinical Laboratory Analysis published by Wiley Periodicals, Inc.Shape memory polymer (SMP) foams are a promising material for hemostatic dressings due to their biocompatibility, high surface area, excellent shape recovery, and ability to quickly initiate blood clotting. Biodegradable SMP foams could eliminate the need for a secondary removal procedure of hemostatic material from the patients' wound, further facilitating wound healing. In this study, we developed hydrolytically and oxidatively biodegradable SMP foams by reacting polyols (triethanolamine or glycerol) with 6-aminocaproic acid or glycine to generate foaming monomers with degradable ester bonds. These monomers were used in foam synthesis to provide highly crosslinked SMP foam structures. The ester-containing foams showed clinically relevant thermal properties that were comparable to controls and excellent shape recovery within eight min. Triethanolamine-based ester-containing foams showed interconnected porous structure along with increased mechanical strength. Faster hydrolytic and oxidative biodegradation rates were achieved in ester-containing foams in comparison to controls.

The capacity to diagnose cancer with the existing endogenous biomarkers remains limited because biomarkers usually act at the tumor site and are thus challenging to be detected directly from body fluids with high sensitivity and specificity, especially in the early stage of tumorigenesis. Here, we demonstrate an exogenous tumor-penetrating nanomarker composed of fluorescent nanoparticles conjugated with specific fluorescein-labeled peptides. The injectable nanomarkers perform four functions they penetrate the tumor, target sites of cancer, cleave specific peptides by on-target protease, and drop off the labeled peptide into host urine for fluorescent detection. Sensitive in vivo tracking and monitoring of the cyclic process of the nanomarker was also accomplished. The nanomarker can noninvasively diagnose and monitor tumors with a volume of about 17 mm3 without invasive core biopsies. Enhanced capacity of early point-of-care detection for cancer is accomplished by receptor-dependent specificity of the signal generation in the urine compared with clinically used blood biomarkers.The isomeric heterogeneity of glycans poses a great challenge for their analysis. While combining ion mobility spectrometry (IMS) with tandem mass spectrometry is a powerful means for identifying and characterizing glycans, it has difficulty distinguishing the subtlest differences between isomers. Cryogenic infrared spectroscopy provides an additional dimension for glycan identification that is extremely sensitive to their structure. Our approach to glycan analysis combines ultrahigh-resolution IMS-IMS using structures for lossless ion manipulation (SLIM) with cryogenic infrared spectroscopy. We present here the design of a SLIM board containing a series of on-board traps in which we perform collision-induced dissociation (CID) at pressures in the millibar range. We characterize the on-board CID process by comparing the fragments generated from a pentapeptide to those obtained on a commercial tandem mass spectrometer. We then apply our new technique to study the mobility and vibrational spectra of CID fragments from two human milk oligosaccharides. Comparison of both the fragment drift times and IR spectra with those of suitable reference compounds allows us to identify their specific isomeric form, including the anomericity of the glycosidic linkage, demonstrating the power of this tool for glycan analysis.Splice variants visualization is pivotal for a deeper understanding of cell growth and development. However, it remains technically challenging due to short lengths, similar sequences, and low abundance. The existing single-cell imaging strategies suffer from nonspecific amplification that causes considerable noise during visualization of the splice variants. Herein we develop a new RNA-primed amplification strategy for noise-suppressed visualization of single-cell splice variants. Block probes were designed to specifically identify the conjugated region of exons in mRNA, which was then digested by endonuclease and provided a hydroxyl group at the 3' terminal. The RNA target can act as primer to trigger rolling circle amplification, achieving visualization of splice variants with noise suppressed to nearly zero. We further explored the expression and distribution of BRCA1 splice variants in three breast cell lines, revealing cell-type specific mapping of this cancer suppressor gene.A highly efficient tetradentate PNNP-type Ir photocatalyst, Mes-IrPCY2, was developed for the reduction of carbon dioxide. The photocatalyst furnished formic acid (HCO2H) with 87% selectivity together with carbon monoxide to achieve a turnover number of 2560, which is the highest among CO2 reduction photocatalysts without an additional photosensitizer. Mes-IrPCY2 exhibited outstanding photocatalytic CO2 reduction activity in the presence of the sacrificial electron source 1,3-dimethyl-2-phenyl-2,3-dihydro-1H-benzo[d]imidazole (BIH) in CO2-saturated N,N-dimethylacetamide under irradiation with visible light. The quantum yield was determined to be 49% for the generation of HCO2H and CO. Electron paramagnetic resonance and UV-vis spectroscopy studies of Mes-IrPCY2 with a sacrificial electron donor revealed that the one-electron-reduced species is the key intermediate for the selective formation of HCO2H.The ability to create ways to control drug activation at specific tissues while sparing healthy tissues remains a major challenge. The administration of exogenous target-specific triggers offers the potential for traceless release of active drugs on tumor sites from antibody-drug conjugates (ADCs) and caged prodrugs. We have developed a metal-mediated bond-cleavage reaction that uses platinum complexes [K2PtCl4 or Cisplatin (CisPt)] for drug activation. Key to the success of the reaction is a water-promoted activation process that triggers the reactivity of the platinum complexes. Under these conditions, the decaging of pentynoyl tertiary amides and N-propargyls occurs rapidly in aqueous systems. In cells, the protected analogues of cytotoxic drugs 5-fluorouracil (5-FU) and monomethyl auristatin E (MMAE) are partially activated by nontoxic amounts of platinum salts. Additionally, a noninternalizing ADC built with a pentynoyl traceless linker that features a tertiary amide protected MMAE was also decaged in the presence of platinum salts for extracellular drug release in cancer cells. Finally, CisPt-mediated prodrug activation of a propargyl derivative of 5-FU was shown in a colorectal zebrafish xenograft model that led to significant reductions in tumor size. Overall, our results reveal a new metal-based cleavable reaction that expands the application of platinum complexes beyond those in catalysis and cancer therapy.CaF2 seems to be the ideal substrate material for the infrared spectroscopy of organic and biological layers, since its refractive index is very similar to that of these materials. As a consequence of this similarity, the baseline, i.e., the signal strength in nonabsorbing regions, is nearly flat and does not show notable interference fringes. Nevertheless, as absorption is always accompanied by changes of the refractive index, the refractive indices of substrate and layer can substantially deviate around absorption bands. As a consequence, changes in band intensity, shape, and position result, which aggravate a correct interpretation of the spectra. For layers with thicknesses between 1 and 2 μm, we show experimentally, that deviations from the Beer-Lambert law of up to ±10% occur. Calculations reveal that for thinner layers these deviations are even higher. https://www.selleckchem.com/products/cct128930.html These results suggest the application of a wave-optics based formalism to correct the deviations. We introduce such a formalism and prove that it is able to remove the errors.

to day 14. When transplanted into mice, the scaffold with cells cultured for 7 days exhibited the most prominent osteogenesis. The scaffold, which was transplanted subperiosteally in the skull, retained its shape and was replaced with regenerated bone over a large area of the field of view. Conclusion Osteoblasts before full maturation are most efficient for bone regeneration, and the pre-culture period suitable for cells to be loaded onto a β-TCP/RCP hybrid scaffold is approximately 7 days.This β-TCP/RCP hybrid scaffolds will also be useful for bone augmentation.Background Risedronate increases bone mineral density (BMD) and reduces fracture risk, but treatment response may depend on the baseline state of bone turnover. Data regarding the selection of therapeutic drugs or the prediction of therapeutic effects with baseline levels of bone turnover markers (BTMs) as a reference are insufficient. We hypothesized that when the baseline levels of BTMs are higher, baseline BMD might be lower, changes in BMD at 12 months after risedronate treatment might be higher, and the reduction of fracture incidence might be greater. This study aimed to analyze the data of a phase III clinical trial of risedronate from Japan to investigate the relationships between baseline BTM levels and (1) baseline BMD, (2) changes in BMD at 12 months after the start of treatment, and (3) the incidence of new vertebral fractures. Methods This post-hoc analysis included 788 postmenopausal women with osteoporosis whose baseline BTM levels as well as baseline and endpoint BMDs were measured. RelationshBTM levels increased, baseline BMD tended to be lower and the increase in BMD with 12-month risedronate treatment was higher. However, BMD could still be increased even if the baseline BTM levels are within the normal range. Combined with available evidence, baseline BTMs may not have an important role in deciding the optimal therapy. To elucidate the relationship between baseline BTM levels and long-term fracture risk, it will be necessary to conduct more large-scale studies with a longer follow-up period in severe osteoporotic patients with a high fracture risk. Mini abstract We evaluated the significance of baseline bone turnover markers in the response to risedronate treatment. The increase in the bone mineral density (BMD) with the 12-month treatment may be higher when the state of bone turnover at baseline is higher, and BMD could still be increased even if the baseline bone turnover is within the normal range.A growing body of literature supports the role of apolipoproteins present in HDL in the treatment of pro-inflammatory diseases including cancer. https://www.selleckchem.com/products/vacuolin-1.html We examined whether bovine HDL (bHDL) and three dual-domain peptides, namely AEM-28 and its analog AEM-28-2, and HM-10/10, affect tumor growth and development in mouse models of ovarian and colon cancer. We demonstrate that bHDL inhibits mouse colorectal cancer cell line CT26-mediated lung tumor development, and mouse ovarian cancer cell line ID8-mediated tumor burden. We also demonstrate that, although to different degrees, dual-domain peptides inhibit cell viability of mouse and human ovarian and colon cancer cell lines, but not that of normal human colonic epithelial cells or NIH3T3 mouse fibroblasts. Dual-domain peptides administered subcutaneously or in a chow diet decrease CT26 cell-mediated tumor burden, tumor growth, and tumor dissemination in BALB/c mice. Plasma levels of lysophosphatidic acid (LPA) are significantly reduced in mice that received bHDL and the dual-domain peptides, suggesting that reduction by effecting accumulation and/or synthesis of pro-inflammatory lipids may be one of the mechanisms for the inhibition of tumor development by bHDL and the dual-domain peptides. Our studies suggest that therapeutics based on apolipoproteins present in HDL may be novel agents for the treatment of epithelial adenocarcinomas of the ovary and colon.Efficient transgene delivery is critical for genetic manipulation and therapeutic intervention of target cells. Two well-characterized integrative systems have been described that rely on viral and nonviral vectors. However, use of viral vectors for gene therapy has been associated with several safety concerns. Here, we report a virus-free method for stable transgenesis based on the reaction of retroviral integrase. We constructed a gateway cloning compatible vector containing two truncated long terminal repeat (LTR) sequences (dLTR) that flank the transgene cassette. Notably, 5'-ACTG-3' and blunt-end restriction cutting sites were also embedded at the end of dLTR to be recognized by HIV-1 integrase. When performing coinjection of transgene cassette and integrase mRNA into zebrafish embryos at one cell stage, there were 50% to 55% of injected embryos expressing a marker gene in a desired pattern. When applying our method in mammalian cells, there were 42% of cultured human epithelial cell lines showing stable integration. These results demonstrated that our method can successfully insert an exogenous gene into the host genome with highly efficient integration. Importantly, this system operates without most of the viral components while retaining effective stable transgenesis. We anticipate this method will provide a convenient, safe, and highly efficient way for applications in transgenesis and gene therapy.Activation, infection, and eventual depletion of human immunodeficiency virus (HIV)-specific cluster of differentiation 4 (CD4) T cells are the crucial pathogenetic events in acquired immunodeficiency syndrome (AIDS). We developed a cell and gene therapy to reconstitute HIV-specific CD4 T cells and prevent their destruction by HIV. Antigen-specific CD4 T cells will provide helper functions to support antiviral cytotoxic T lymphocyte (CTL) function and the production of virus-specific antibodies. However, ex vivo expansion of HIV-specific CD4 T cells is poor and previous gene therapies focused on bulk CD4 T cells without enriching for an antigen-specific subset. We developed a method for manufacturing autologous CD4+ T cell products highly enriched with Gag-specific T cells. Rare Gag-specific CD4 T cells in peripheral blood mononuclear cells (PBMCs) were increased nearly 1,000-fold by stimulating PBMC with Gag peptides, followed by depleting nontarget cells and transducing with lentivirus vector AGT103 to protect against HIV-mediated depletion and inhibit HIV release from latently infected cells.

Objectives People with dementia can face barriers when trying to access care after a diagnosis, particularly in young-onset dementia (YOD). Little is known about the effects of ethnicity on the use of anti-dementia medication and variations between age groups. The aim of this study was to analyze national data on variations in the uptake of anti-dementia medication between people with YOD and late-onset dementia (LOD). Design Cross-sectional longitudinal cohort study. Setting Data from the U.S. National Alzheimer's Coordinating Centre were obtained from September 2005 to March 2019. Participants First visits of people with a diagnosis of Alzheimer's disease (AD) dementia, Lewy body dementia (LBD), and Parkinson's disease dementia (PDD) were included. Measurements Logistic regression was used to analyze the effects of education and ethnicity on use of cholinesterase inhibitors and memantine, accounting for YOD/LOD, gender, living situation, severity stage, and comorbidities. https://www.selleckchem.com/products/acetylcysteine.html Results In total, 15,742 people with AD dementia and LBD/PDD were included, with 11,019 PwD having completed a first follow-up visit. Significantly more people with YOD used memantine than those with LOD, while fewer used cholinesterase inhibitors. PwD from minority ethnic backgrounds used memantine and cholinesterase inhibitors less often than those from a White ethnic background. Logistic regression analysis showed that ethnicity was a significant determinant of both memantine and cholinesterase inhibitors usage, while education was only a significant determinant for memantine usage. Conclusions Findings highlight the impact of social factors on current usage of anti-dementia medication and the need for more resources to enable equitable use of anti-dementia medication.Objective To determine whether carbapenem consumption and Pseudomonas aeruginosa resistance rates can be used as benchmarks to compare and improve antimicrobial stewardship programs across multiple pediatric hospitals. Design A prospective study. Setting and participants Healthcare institutions in Japan with >100 pediatric beds. Methods An annual survey of the total days of therapy (DOT) per 1,000 patient days for carbapenem antibiotics (meropenem, imipenem-cilastatin, panipenem-betamipron, doripenem) and susceptibility rates of Pseudomonas aeruginosa to meropenem and imipenem-cilastatin from each institution was conducted over a 7-year period. Data were reported to the administration, as well as to the infection control team, of each institution annually. Results Data were obtained from 32 facilities. The median total carbapenem DOT per 1,000 patient days was 16.6 and varied widely, with a range of 2.7 to 59.0. The median susceptibility to meropenem was 86.6%, ranging from 78.6% to 96.6%. We detected an inverse correlation between total carbapenem DOT versus susceptibility (r = - 0.36; P less then .01). Over the 7-year period, the DOT per 1,000 patient days of carbapenem decreased by 27% from a median of 16.0 to 11.7 (P less then .01). We also observed an improvement in susceptibility to meropenem from a median of 87% to 89.7% (P = .01) and to imipenem-cilastatin from 79% to 85% (P less then .01). The decreases in the use of carbapenem were greater in institutions with antimicrobial stewardship programs led by pediatric infectious disease specialists. Conclusions Antimicrobial use and resistance, targeting carbapenems and P. aeruginosa, respectively, can serve as benchmarks that can be utilized to promote antimicrobial stewardship across pediatric healthcare institutions.Antimicrobial stewardship of anti-infectives prescribed upon hospital discharge was implemented to improve the rate of appropriate prescribing at discharge. Appropriate prescribing significantly improved from 47.5% to 85.2% (P less then .001), antimicrobial days of therapy decreased, and 30-day readmission rates decreased. Discharge antimicrobial stewardship was effective in improving anti-infective prescribing practices.Tuberculosis considered as a chronic infectious disease caused by Mycobacterium tuberculosis, may invade all organs but mainly affects the lungs [1].In overall, disseminated TB is rare in immunocompetent patients and its association with seborrheic keratosis has never been reported. We reported a54-year-old man with a complaint prolonged fever, abdominal pain, weight loss and lymphadenopathy without any immunosuppression who was eventually treated based on the diagnosis of diffuse tuberculosis.Background Chronotherapeutics, the drug delivery based on circadian rhythm, is recently gaining much attention worldwide. Various diseases like asthma, hypertension, and arthritis show circadian variation that demands time scheduled drug release for effective drug action. So, Pulsatile drug delivery system have been designed to confer preprogrammed drug delivery. Objective In the present study, a '3 Cap' pulsatile drug delivery system has been developed, optimized and characterized in order to achieve floating and pulsatile release of Ramipril. Methods An optimal response surface design was employed to investigate the effect of isopropanol formaldehyde vapours for varying time on drug release from the capsules. '3 Cap' pulsatile drug delivery system was evaluated in terms of floating time, density, effect of gastric flow rate and type of dissolution apparatus on drug release. Results Independent variables exhibited significant effect on the drug release of the prepared formulations. Results showed that time between the release of fractions of dose increased with increase in formaldehyde isopropanol ratio and duration of exposure to formaldehyde vapours with no effect of gastric flow rate. Conclusion The design results revealed that an optimum exposure of 12 of isopropanol formaldehyde vapours for sixty minutes resulted in desired release of second pulse of dose after a predetermined lag time of 5 hours as desired. '3Cap' system was successful in achieving floating and pulsed release of hypertensive drug opening a 'new lease of life' to the existing drug molecule.Background BSI calculated from bone scintigraphy using 99mtechnetium-methylene diphosphonate (99mTc-MDP) is used as a quantitative indicator of metastatic bone involvement in bone metastasis diagnosis, therapeutic effect assessment, and prognosis prediction. However, the BONE NAVI, which calculates BSI, only supports bone scintigraphy using 99mTc-MDP. Aims We developed a method in collaboration with the Tokyo University of Agriculture and Technology to calculate bone scan index (BSI) employing deep learning algorithms with bone scintigraphy images using 99mtechnetiumhydroxymethylene diphosphonate (99mTc-HMDP). We used a convolutional neural network (CNN) enabling the simultaneous processing of anterior and posterior bone scintigraphy images named CNNapis. Objectives The purpose of this study is to investigate the usefulness of the BSI calculated by CNNapis as bone imaging and bone metabolic biomarkers in patients with bone metastases from prostate cancer. Methods At our hospital, 121 bone scintigraphy scans using 99mTc-HMDP were performed and analyzed to examine bone metastases from prostate cancer, revealing the abnormal accumulation of radioisotope (RI) at bone metastasis sites.

A co-crystal was obtained based on donor-acceptor interactions. The obvious charge transfer from the linear donor to the triangular acceptor units results in a quasi-two-dimensional CT complex with excellent near-infrared photothermal conversion efficiency. The co-crystals further acted as an excellent photothermal material in seawater desalination.Background and aim IgE-mediated immune responses contribute to the pathogenesis of eosinophilic esophagitis (EoE). Interleukin (IL)-4 is a well-established cytokine involved in B cell activation, immunoglobulin (Ig) E production and isotype class switching. Earlier reports indicated that IL-15, B cells and IgE are induced in EoE pathogenesis. Therefore, we hypothesized that induced IL-15 and IgE may have a significant correlation in promoting EoE pathogenesis. Methods Accordingly, we performed ELISA, qPCR, flowcytometric and immunostaining analyses to examine IgE, B cells, eosinophils and mast cells in the esophagus of IL-15 overexpressed mice following EoE induction. Results Herein, we show that IL-15 overexpressed mice indeed have induced baseline IL-4, B cells, eosinophils, mast cells and IgE levels in the blood and esophagus. Further, we observed that IL-15 overexpressed mice show induction of IgE, and accumulation of degranulated eosinophils and mast cells in allergen-induced experimental EoE. Notably, despite induced blood IgE, esophageal eosinophilia is not induced in intestinal fatty acid binding protein IL-15 overexpressed gene (Fabpi-IL-15) mice. Fabpi-IL-15 transgenic mice showed IgE in the blood and intestine and intestinal eosinophilia, but no esophageal eosinophilia at baseline and comparable eosinophils in the esophagus of saline and allergen challenged Fabpi-IL-15 mice. Similarly, allergen challenged IL-15 gene-deficient mice show reduced IgE and esophageal eosinophilia in allergen-induced experimental EoE. https://www.selleckchem.com/products/ljh685.html Conclusions Taken together, we for the first time provide direct evidence that tissue-specific IL-15 induced IgE mediated responses, not systemic IgE is critical in promoting EoE pathogenesis.In theory, bimetallic UiO-66(ZrCe) and UiO-66(ZrHf) metal-organic frameworks (MOFs) are extremely versatile and attractive nanoporous materials as they combine the high catalytic activity of UiO-66(Ce) or UiO-66(Hf) with the outstanding stability of UiO-66(Zr). Using in situ high-pressure powder X-ray diffraction, however, we observe that this expected mechanical stability is not achieved when incorporating cerium or hafnium in UiO-66(Zr). This observation is akin to the earlier observed reduced thermal stability of UiO-66(ZrCe) compounds. To elucidate the atomic origin of this phenomenon, we chart the loss-of-crystallinity pressures of 22 monometallic and bimetallic UiO-66 materials and systematically isolate their intrinsic mechanical stability from their defect-induced weakening. This complementary experimental/computational approach reveals that the intrinsic mechanical stability of these bimetallic MOFs decreases nonlinearly upon cerium incorporation but remains unaffected by the zirconium hafnium ratio. Additionally, all experimental samples suffer from defect-induced weakening, a synthesis-controlled effect that is observed to be independent of their intrinsic stability.

Unfortunately, the vast majority of polymeric membranes are produced via an unsustainable and environmentally unfriendly process that requires large amounts of harsh reprotoxic chemicals such as N-methyl-2-pyrrolidinone and dimethylformamide. In this work, we investigate an aqueous phase separation (APS) system that uses weak polyelectrolytes, whose charge is dependent on the pH (weak polyelectrolytes), to produce membranes. Specifically the copolymer polystyrene-alt-maleic acid (PSaMA) is used. PSaMA contains responsive monomers, required for APS, and also unresponsive hydrophobic monomers that provide mechanical stability to the resultant membranes. This work demonstrates that by controlling the precipitation of PSaMA, it is possible to prepare a wide range of membranes; from microfiltration membranes capable of treating oily waste water to dense nanofiltration-type membranes with excellent micropollutant retentions and high mechanical stability. While similar materials in prior work could only withstand 4 bar, the membranes presented here demonstrate stable operation up to 20 bar. The only solvents used in this APS system are water and the green solvent acetic acid, thus making our APS process significantly more sustainable and environmentally friendly as compared to the conventional membrane fabrication methods.

The SH were fabricated by extruding, dropwise, a cationic cellulose nanofibril (CCNF) dispersion into an oppositely charged poly(acrylic acid) (PAA) bath. The SH have a solid-like CCNF-PAA shell, acting as a semipermeable membrane, and a liquid-like CCNF suspension in the core. Swelling behavior of the SH was dependent on the osmotic pressure of the aging media. Swelling could be suppressed by increasing the ionic strength of the media as this enhanced interfibrillar interactions and thus strengthened the outer gel membrane. We further validated a potential application of SH as reusable matrixes for glucose oxidase (GOx) entrapment, where the SH work as microreactors from which substrate and product are freely able to migrate through the SH shell while avoiding enzyme leakage.

This study aimed to assess attitudes, opportunities, and challenges for clinical pharmacy services from the health care providers' perspective in Mizan-Tepi University Teaching Hospital. Methods A cross-sectional study was conducted among physicians, nurses, pharmacy professionals, and public health officers working in Mizan-Tepi University Teaching Hospital. A total of 119 health care providers participated in the study, and data were collected using a pretested self-administered questionnaire. The study tool was designed based on the instruments used in the previously conducted studies. Collected data were coded, entered, and analyzed using Statistical Package for the Social Sciences (SPSS, version 21). Furthermore, the descriptive and inferential statistics were performed. Results Out of 119 health care providers included in the study, 59.66% of them were nurses.
