Residents often are involved in discussions with families regarding brain death/death by neurologic criteria (BD/DNC); however, they receive no standardized training on this topic. We hypothesized that residents are uncomfortable with explaining BD/DNC and that formal didactic and simulated training will improve residents' comfort and skill in discussions surrounding BD/DNC.

We partnered with our organ procurement organization (OPO) to create an educational program regarding BD/DNC consisting of a didactic component, and role-play scenarios with immediate individualized feedback. Residents completed pre- and post-training surveys.

This study included participants from 16 academic and community institutions across New Jersey, Pennsylvania, and Delaware that are within our OPO's region.

Subjects were recruited using convenience sampling based on the institution and training programs' willingness to participate. A total of 1422 residents at participated in the training from 2009 to 2020. 1389 (97.7%) participants competed the pre-intervention survey, while 1361 (95.7%) completed the post-intervention survey.

Prior to the training, only 56% of residents correctly identified BD/DNC as synonymous with death. Additionally, 40% of residents had explained BD/DNC to families at least once, but 41% of residents reported never having been taught how to do so. The biggest fear reported in discussing BD/DNC with families was being uncomfortable in explaining BD/DNC (48%). After participating in the training, 99% of residents understood the definition of BD/DNC and 92% of residents felt comfortable discussing BD/DNC with families.

Participation in a standardized curriculum improves residents' understanding of BD/DNC and their comfort in discussing BD/DNC with families.

This study was conducted to describe gender differences in physician burnout and professional fulfillment and to explore their potential contributors.

This was a single-center, cross-sectional survey study of physician faculty at Brigham and Women's Hospital, an academic medical center in Boston. The population included all physician faculty who practiced clinical medicine in 2017 (n = 2,388). The study was conducted using the Stanford Physician Wellness Survey. Burnout and professional fulfillment were the main outcome measures assessed. Other variables assessed included ratings of culture of wellness, personal resilience, and efficiency of practice factors associated with physician experience.

The study population consisted of 1,066 faculty, of whom 46.4% were female and 59.8% were younger than 50. Female physicians reported significantly higher rates of burnout (42.4% vs. 34.4%, p = 0.01) and lower rates of professional fulfillment (35.1% vs. selleck chemicals 50.4%, p < 0.01) than male physicians. Female physiciany. Culture of wellness factors and self-compassion may contribute to gender differences in burnout and professional fulfillment and potentially represent modifiable targets for efforts seeking to eliminate gender disparities in physicians' workplace experiences.Schizophrenia provides a quintessential disease model of how disturbances in the molecular mechanisms of neurodevelopment lead to disruptions in the emergence of cognition. The central and often persistent feature of this illness is the disorganisation and impoverishment of language and related expressive behaviours. Though clinically more prominent, the periodic perceptual distortions characterised as psychosis are non-specific and often episodic. While several insights into psychosis have been gained based on study of the dopaminergic system, the mechanistic basis of linguistic disorganisation and impoverishment is still elusive. Key findings from cellular to systems-level studies highlight the role of ubiquitous, inhibitory processes in language production. Dysregulation of these processes at critical time periods, in key brain areas, provides a surprisingly parsimonious account of linguistic disorganisation and impoverishment in schizophrenia. This review links the notion of excitatory/inhibitory (E/I) imbalance at cortical microcircuits to the expression of language behaviour characteristic of schizophrenia, through the building blocks of neurochemistry, neurophysiology, and neurocognition.
This study developed and piloted the first online training package to support implementation and delivery of brief smoking cessation interventions for therapeutic radiographers in four radiotherapy departments in England.

A previously reported systematic literature review and data analysis from the previously reported pre-focus group questionnaire and focus groups enabled the development of an online training package. The questionnaire was repeated by the participating therapeutic radiographers following completion of the training resource (n=31). The results of the comparative questions from the pre and post questionnaires were analysed using the Statistical Package for Social Sciences (SPSS Version 24).

In total, 43 therapeutic radiographer participants completed the pre-questionnaire and 31 participants continued to complete the post questionnaire, having completed the online training package. The previously conducted focus groups identified several barriers to the delivery of smoking cessation, thathas proven to be effective in the sample within this study and should be disseminated and evaluated more widely across radiotherapy provision within the United Kingdom.

Increased intrapancreatic fat is associated with pancreatic diseases; however, there are no established objective diagnostic criteria for fatty pancreas. On non-contrast computed tomography (CT), adipose tissue shows negative Hounsfield Unit (HU) attenuations (-150 to-30 HU). Using whole organ segmentation on non-contrast CT, we aimed to describe whole gland pancreatic attenuation and establish 5th and 10th percentile thresholds across a spectrum of age and sex. Subsequently, we aimed to evaluate the association between low pancreatic HU and risk of pancreatic ductal adenocarcinoma (PDAC).

The whole pancreas was segmented in 19,456 images from 469 non-contrast CT scans. A convolutional neural network was trained to assist pancreas segmentation. Mean pancreatic HU, volume, and body composition metrics were calculated. The lower 5th and 10th percentile for mean pancreatic HU were identified, examining the association with age and sex. Pre-diagnostic CT scans from patients who later developed PDAC were compared to cancer-free controls.

Less than 5th percentile mean pancreatic HU was significantly associated with increase in BMI (OR 1.07; 1.03-1.11), visceral fat (OR 1.37; 1.15-1.64), total abdominal fat (OR 1.12; 1.03-1.22), and diabetes mellitus type 1 (OR 6.76; 1.68-27.28). Compared to controls, pre-diagnostic scans in PDAC cases had lower mean whole gland pancreatic HU (-0.2 vs 7.8, p=0.026).

In this study, we report age and sex-specific distribution of pancreatic whole-gland CT attenuation. Compared to controls, mean whole gland pancreatic HU is significantly lower in the pre-diagnostic phase of PDAC.

The carboxyl-ester lipase (CEL) gene contains a variable number of tandem repeats (VNTR) region. It remains unclear whether the number of repeats in the CEL VNTR is related to the risk of pancreatic diseases. The aim of this study was to investigate whether CEL VNTR length is associated with idiopathic chronic pancreatitis (ICP), alcoholic chronic pancreatitis (ACP), or pancreatic cancer in a cohort of Chinese patients.

CEL VNTRs were genotyped in patients diagnosed with ICP (n=771), ACP (n=222), or pancreatic cancer (n=263), and in healthy controls (n=927). CEL VNTR lengths were determined using a screening method combining PCR and DNA fragment analysis.

Overall, the CEL VNTR lengths ranged from 5 to 22 repeats, with the 16-repeat allele ('normal' size, N) accounting for 73.82% of all observed alleles. The VNTR allele frequencies and genotype distributions were not significantly different between healthy controls and patients with ACP or pancreatic cancer. For the ICP group, allele frequencies did not differ significantly from the controls, while the frequency of the SS genotype (homozygosity for 5-15 repeats) was significantly higher in the patients (4.67%) than in the controls (1.94%) (p=0.0014; OR=2.47; 95% CI=1.39-4.39).

There were no associations between the CEL VNTR length and ACP or pancreatic cancer. However, homozygosity for short VNTR lengths may confer susceptibility to ICP.

Astigmatism is a highly prevalent refractive error and while studies typically focus to describe the axis symmetry between eyes, little is known about the refractive symmetry. Therefore, this study determined the astigmatic power symmetry between eyes in a large clinic population.

A clinical chart review was conducted at three optometric practices in the United States, the United Kingdom and Canada and subjective refraction data from 88,891 patients 14-70years of age who presented with at least -0.25DC refractive astigmatism in at least one eye were included in the analysis. Data were obtained at these practices between January 2014 and March 2017. The overall distribution (%) and magnitude (DC) of astigmatism was determined and refractive differences between eyes were identified.

The mean age of the patients was 42.1±15.9years and included 51,685 (58%) female and 37,206 (42%) male patients. In this data pool of 177,782 eyes, 10.9% required zero astigmatic correction, while 56.2% had astigmatism of -0.25 to -0.75DC. In total 23.9% of patients presented with astigmatism of at least -0.75DC in only one eye, while the other eye had 0 to -0.50DC. Overall, the difference in astigmatism between eyes was less than -0.75DC for 82.1% of astigmatic patients. For patients who presented with astigmatism of -1.00DC in the right eye, 80.8% of them had an astigmatic prescription of -1.00±0.50DC in the left eye. link3 For an astigmatic prescription of -4.00DC in the right eye, only 40.6% of patients exhibited astigmatism of -4.00DC±0.50DC in the left eye.

The majority of patients exhibited a difference in astigmatism between eyes of less than -0.75DC, however the refractive cylinder power symmetry was significantly lower in patients with higher refractive astigmatism.
