This research note identifies patterns of stressor exposure among Canadian workers, their stratification by occupational and socio-demographic factors, and their relationship to high self-reported work stress. check details Using latent class analysis and data from the Canadian Community Health Survey we examine the intersection of six stressors, identifying five distinct patterns (Few stressors, Multiple stressors, Physical, Monotonous, and Chaotic patterns of stressor exposure). Results show that the patterns of stressor exposure are stratified by gender, education, income, age group, and occupation; as well as give insight on how particular patterns of stressor exposure relate to individual perceptions of high self-reported work stress. The project also provides a research example of using quantitative data to examine qualitative differences in patterns of experience that provide more nuanced insight into complex social phenomena.
The Paris system (TPS) for Reporting Urinary Cytology provides a standardized reporting system whose main focus is the diagnosis of high-grade urothelial carcinoma (HGUC). We conducted a study to see the impact of The Paris System on our cytologic diagnoses with associated histology.

We reviewed our pathology database regarding urinary specimens in the year before implementation of The Paris System and the year after. We gathered the data regarding cytologic diagnosis and concurrent/subsequent histology.

Over a 1-year period from 2016-2017, 486 urine cytology specimens were identified before implementation of The Paris System and diagnosed as follows 83% benign/negative, 10% atypical, 2% suspicious, 5% HGUC, 0.2% low grade urothelial neoplasm (LGUN), and 0.2% unsatisfactory. Over a next 1-year period from 2017 to 2018, 602 specimens used TPS and diagnosed as follows 85% negative for HGUC, 6% atypical, 3% suspicious, 4% HGUC, 0.17% LGUN, and 2% unsatisfactory. Although, not listed as a standardized categcarcinoma. Also, the NHL subcategory had a high positive predictive value for diagnosing low grade urothelial neoplasms.The cantharidin-induced skin blister is a simple model for investigating cell migration and inflammatory mediator production at a site of inflammation. Application of cantharidin solution to the ear pinna results in formation of a blister with cell influx and induction of inflammatory mediators at the skin site, as well as local swelling of the ear pinna. The model can be used for investigating anti-inflammatory compounds, such as dexamethasone, and for preclinical drug discovery research, especially in areas where neutrophilic inflammation plays a role in disease pathophysiology. The cantharidin blister model is one of very few translational models described in humans, and the mechanism of inflammation induction is comparable in mice and man. In human studies, the cantharidin blister assay has been used to assess the effects of potential new therapies in early-stage clinical studies. © 2021 Novartis AG.

A systematic search of studies on the epidemiology of hypertension in Nigeria, published on or after January 1990, was conducted. The authors employed random-effects meta-analysis on extracted crude hypertension prevalence, and awareness, treatment, and control rates. Using a meta-regression model, overall hypertension cases in Nigeria in 1995 and 2020 were estimated. Fifty-three studies (n = 78 949) met our selection criteria. Estimated crude prevalence of pre-hypertension (120-139/80-89 mmHg) in Nigeria was 30.9% (95% confidence interval [CI] 22.0%-39.7%), and the crude prevalence of hypertension (≥140/90 mmHg) was 30.6% (95% CI 27.3%-34.0%). When adjusted for age, study period, and sample, absolute cases of hypertension increased by 540% among individuals aged ≥20 years from approximately 4.3 million individuals in 1995 (age-adjusted prevalence 8.6%, 95% CI 6.5-10.7) to 27.5 million individuals with hypertension in 2020 (age-adjusted prevalence 32.5%, 95% CI 29.8-35.3). The age-adjusted prevalence was only significantly higher among men in 1995, with the gap between both sexes considerably narrowed in 2020. Only 29.0% of cases (95% CI 19.7-38.3) were aware of their hypertension, 12.0% (95% CI 2.7-21.2) were on treatment, and 2.8% (95% CI 0.1-5.7) had at-goal blood pressure in 2020. Our study suggests that hypertension prevalence has substantially increased in Nigeria over the last two decades. Although more persons are aware of their hypertension status, clinical treatment and control rates, however, remain low. These estimates are relevant for clinical care, population, and policy response in Nigeria and across Africa.Rice sheath blight (RSB) is an economically significant disease affecting rice yield worldwide. Genetic resistance to RSB is associated with multiple minor genes, with each providing a minor phenotypic effect, but the underlying dominant resistance genes remain unknown. A genome-wide association study (GWAS) of 259 diverse rice varieties, with genotypes based on a single nucleotide polymorphism (SNP) and haplotype, was conducted to assess their sheath blight reactions at three developmental stages (seedlings, tillering and booting). A total of 653 genes were correlated with sheath blight resistance, of which the disease resistance protein RPM1 (OsRSR1) and protein kinase domain-containing protein (OsRLCK5) were validated by overexpression and knockdown assays. We further found that the coiled-coil (CC) domain of OsRSR1 (OsRSR1-CC) and full-length OsRLCK5 interacted with serine hydroxymethyltransferase 1 (OsSHM1) and glutaredoxin (OsGRX20), respectively. It was found that OsSHM1, which has a role in the reactive oxygen species (ROS) burst, and OsGRX20 enhanced the antioxidation ability of plants. A regulation model of the new RSB resistance though the glutathione (GSH)-ascorbic acid (AsA) antioxidant system was therefore revealed. These results enhance our understanding of RSB resistance mechanisms and provide better gene resources for the breeding of disease resistance in rice.
