Background
China is vulnerable to zoonotic disease transmission due to a large agricultural work force, sizable domestic livestock population, and a highly biodiverse ecology. To better address this threat, representatives from the human, animal, and environmental health sectors in China held a One Health Zoonotic Disease Prioritization (OHZDP) workshop in May 2019 to develop a list of priority zoonotic diseases for multisectoral, One Health collaboration.

Methods
Representatives used the OHZDP Process, developed by the US Centers for Disease Control and Prevention (US CDC), to prioritize zoonotic diseases for China. Representatives defined the criteria used for prioritization and determined questions and weights for each individual criterion. A review of English and Chinese literature was conducted prior to the workshop to collect disease specific information on prevalence, morbidity, mortality, and Disability-Adjusted Life Years (DALYs) from China and the Western Pacific Region for zoonotic diseases considered for prioritization.

Results
Thirty zoonotic diseases were evaluated for prioritization. Criteria selected included: 1) disease hazard/severity (case fatality rate) in humans, 2) epidemic scale and intensity (in humans and animals) in China, 3) economic impact, 4) prevention and control, and 5) social impact. Disease specific information was obtained from 792 articles (637 in English and 155 in Chinese) and subject matter experts for the prioritization process. Following discussion of the OHZDP Tool output among disease experts, five priority zoonotic diseases were identified for China: avian influenza, echinococcosis, rabies, plague, and brucellosis.

Conclusion
Representatives agreed on a list of five priority zoonotic diseases that can serve as a foundation to strengthen One Health collaboration for disease prevention and control in China; this list was developed prior to the emergence of SARS-CoV-2 and the COVID-19 pandemic. Next steps focused on establishing a multisectoral, One Health coordination mechanism, improving multisectoral linkages in laboratory testing and surveillance platforms, creating multisectoral preparedness and response plans, and increasing workforce capacity.

ObjectiveTo review the impact of clinical supervision of post-registration/qualification healthcare professionals on healthcare organisational outcomes.BackgroundClinical supervision is a professional support mechanism that benefits patients, healthcare professionals and healthcare organisations. Whilst evidence is growing on the impact of clinical supervision on patient and healthcare professional outcomes, the evidence base for the impact of clinical supervision on organisational outcomes remains weak.MethodsThis review used a convergent segregated approach to synthesise and integrate quantitative and qualitative research findings, as per the Joanna Briggs Institute’s recommendations for mixed methods systematic reviews. Databases searched included CINAHL, Embase, PubMed, PschINFO, and Scopus. Whilst a narrative synthesis was performed to present the findings of the quantitative and qualitative studies, the evidence from both quantitative and qualitative studies was subsequently integrated for a combined presentation. The review followed the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses.ResultsThirty-two studies including 27 quantitative, two qualitative and three mixed methods studies, were included in the review. The results of the quantitative analysis showed that effective clinical supervision was associated with lower burnout and greater staff retention, and effective supervisor was associated with lower burnout and greater job satisfaction. Qualitative findings showed that healthcare professionals believed that adequate clinical supervision could mitigate the risk of burnout, facilitate staff retention, and improve the work environment, while inadequate clinical supervision can lead to stress and burnout. The evidence from quantitative and qualitative studies were complementary of each other.ConclusionClinical supervision can have a variable effect on healthcare organisational outcomes. The direction of this effect appears to be influenced by the effectiveness of both the clinical supervision provided and that of the clinical supervisor. This highlights the need for organisations to invest in high quality supervision practices if maximal gains from clinical supervision are to be attained.

Published: November 2021

IntroductionExtracurricular research programmes (ERPs) may contribute to reducing the current shortage in physician-scientists, but usually select students based on grades only. The question arises if students should be selected based on their motivation, regardless of their previous academic performance. Focusing on grades and lacking to take motivation into account when selecting students for ERPs might exclude an important target group when aiming to cultivate future physician-scientists. Therefore, this study compared ERP students with lower and higher previous academic performance on subsequent academic performance, ERP performance, and motivational factors.MethodsProspective cohort study with undergraduate medical students who filled in a yearly questionnaire on motivational factors. Two student groups participating in an ERP were compared: students with first-year grade point average (GPA) ≥7 versus <7 on a 10-point grading scale. Linear and logistic regressions analyses were used to compare groups on subsequent academic performance (i.e. third-year GPA, in-time bachelor completion), ERP performance (i.e. drop-out, number of credits), and motivational factors (i.e. intrinsic motivation for research, research self-efficacy beliefs, perceptions of research, curiosity), while adjusting for gender and motivational factors at baseline.ResultsThe <7 group had significantly lower third-year GPA, and significantly higher odds for ERP drop-out than the ≥7 group. However, there was no significant between-group difference on in-time bachelor completion and the <7 group was not inferior to the ≥7 group in terms of intrinsic motivation for research, perceptions of research, and curiosity.ConclusionsSince intrinsic motivation for research, perceptions of research, and curiosity are prerequisites of future research involvement, it seems beneficial to focus on motivation when selecting students for ERPS, allowing students with lower current academic performance to participate in ERPs as well.

Published: November 2021

Objectives
Anatomical structure classification is necessary task in medical field, but the inevitable variability of interpretation among experts makes reliable classification difficult. This study aims to introduce cluster analysis, unsupervised machine learning method, for classification of three-dimensional (3D) mandibular canal (MC) courses, and to visualize standard MC courses derived from cluster analysis in the Korean population.

Materials and methods
A total of 429 cone-beam computed tomography images were used. Four sites in the mandible were selected for the measurement of the MC course and four parameters, two vertical and two horizontal parameters were measured per site. Cluster analysis was carried out as follows: parameter measurement, parameter normalization, cluster tendency evaluation, optimal number of clusters determination, and k-means cluster analysis. The 3D MC courses were classified into three types with statistically significant mean differences by cluster analysis.

Results
Cluster 1 showed a smooth line running towards the lingual side in the axial view and a steep slope in the sagittal view. Cluster 2 ran in an almost straight line closest to the lingual and inferior border of mandible. Cluster 3 showed the pathway with a bent buccally in the axial view and an increasing slope in the sagittal view in the posterior area. Cluster 2 showed the highest distribution (42.1%), and males were more widely distributed (57.1%) than the females (42.9%). Cluster 3 comprised similar ratio of male and female cases and accounted for 31.9% of the total distribution. Cluster 1 had the least distribution (26.0%) Distributions of the right and left sides did not show a statistically significant difference.

Conclusion
The MC courses were automatically classified as three types through cluster analysis. Cluster analysis enables the unbiased classification of the anatomical structures by reducing observer variability and can present representative standard information for each classified group.

BackgroundPsoriasis is a chronic inflammatory disease characterized by keratinocyte hyperproliferation and aberrant differentiation with great negative impact on patients’ quality of life (QoL). This study aimed at assessing factors influencing management practice, and QoL and its associated factors among ambulatory psoriatic patients visiting All Africa Leprosy, Tuberculosis and Rehabilitation Training (ALERT) Center in Addis Ababa, Ethiopia.Materials and methodsA cross sectional study was conducted in 207 patients with psoriasis attending the dermatology clinic of ALERT Center in Addis Ababa, Ethiopia. Data were collected using structured questionnaire and patients’ chart review. Dermatology Life Quality Index (DLQI) was used to measure patients’ QoL. Patients’ characteristics were summarized using descriptive statistics and predictors of QoL were identified by binary logistic regression.ResultsAmong 207 study participants, 122 (58.9%) were females. The mean age of the study population was 37.92 (SD = 14.86) years (ranging from 16 to 68 years). The mean age at which diagnosis of psoriasis made was 32 (SD = 13.7) years ranging from 10 to 62 years. The duration of the disease in 112 (54.1%) patients were more than or equal to 5 years. Majority of study participants 145 (70.0%) had plaque psoriasis followed by sebopsoriasis, 24 (11.6%). The majority of plaque psoriasis (80%) cases were managed by topical corticosteroids with or without salicylic acid or coal tar and only 21 (14.5%) treated by methotrexate alone. The mean DLQI was 6.25 corresponding to a moderate effect. Symptoms and feelings were the most affected domains of QoL. Factors associated with poor QoL were female [AOR = 0.17 (95%CI: 0.06, 0.48)], low, above average and high family income ([AOR = 0.12 (95% CI: 0.02, 0.56)], [AOR = 0.06 (95% CI:0.01, 0.32)], and [AOR = 0.03 (95% CI: 0.01, 0.22)]), respectively, and primary education level [AOR = 0.14 (95% CI: 0.03, 0.64)] while being on systemic therapy [AOR = 4.26 (CI: 1.18, 15.35)] was predictor of better QoL. Poor QoL was predominant in females [AOR = 0.17 (95%CI: 0.06, 0.48)], low income [AOR = 0.12 (95% CI: 0.02, 0.56] patients, and patients with primary education level [AOR = 0.14 (95% CI: 0.03, 0.64)]. Patients on systemic therapy [AOR = 4.26 (CI: 1.18, 15.35)] had good QoL.ConclusionOur study identified that topical corticosteroids were the mainstay of psoriasis treatment in the dermatology clinic of ALERT Center in Addis Ababa, Ethiopia. Moderate effect QoL was achieved by study participants based on DLQL score.

Published: November 2021

Background
Some studies revealed that despite having sufficient sun exposure and dietary supply, the level of serum 25(OH)D in Bangladeshi adults is lower than its normal range. Genetic pattern of an individual is also an essential factor that regulates the level of serum 25(OH)D. However, the genetic variations of CYP2R1 (rs10741657) and their association with low serum 25(OH)D level in Bangladeshi adults are yet to be explored.

Objective
This study was conducted to determine the frequency of variants of rs10741657 of CYP2R1 gene and its association with low serum 25(OH)D level among Bangladeshi adults.

Method
This pilot study was conducted among thirty individuals with low serum 25(OH)D level as the study population and ten subjects with sufficient serum 25(OH)D level as controls based on the inclusion and exclusion criteria. Genetic analysis of rs10741657 of CYP2R1 including primer designing, DNA extraction, PCR of target region with purification and Sanger sequencing of the PCR products were done accordingly. For statistical analysis, One-way ANOVA followed by LSD test, Freeman-Halton extension of Fisher’s exact test, Chi-square test (χ2) test and unpaired student t-test were performed.

Results
In this study, genetic variants of CYP2R1 (rs10741657) among the study population were genotype GG (63.30%), GA (30%) and AA (6.7%). Minor allele frequency of the study population was 0.217. The association between GG and GA genotypes of CYP2R1 (rs10741657) with low serum 25(OH)D level among the study population was found and it was statistically significant. Statistically significant differences were also observed between the genotypes and alleles of the study population and controls.

Conclusions
The presence of ‘GG’ and ‘GA’ genotypes of rs1041657 in CYP2R1 gene is associated with low serum 25(OH)D level among Bangladeshi adults in this pilot study.

Published: November 2021

IntroductionTraditional measures of muscular strength require in-person visits, making administration in large epidemiologic cohorts difficult. This has left gaps in the literature regarding relationships between strength and long-term health outcomes. The aim of this study was to test the feasibility and validity of a video-led, self-administered 30-second sit-to-stand (STS) test in a sub-cohort of the U.S.-based Cancer Prevention Study-3.MethodsA video was created to guide participants through the STS test. Participants submitted self-reported scores (n = 1851), and optional video recordings of tests (n = 134). Two reviewers scored all video tests. Means and standard deviations (SD) were calculated for self-reported and video-observed scores. Mean differences (95% confidence intervals (CI)) and Spearman correlation coefficients between self-reported and observed scores were calculated, stratifying by demographic characteristics.ResultsParticipants who uploaded a video reported 14.1 (SD = 3.5) stands, which was not significantly different from the number of stands achieved by the full cohort (13.9 (SD = 4.2),P-difference = 0.39). Self-reported and video-observed scores were highly correlated (ρ = 0.97, mean difference = 0.3, 95% CI = 0.1–0.5). There were no significant differences in correlations by sociodemographic factors (allP-differences ≥0.42).ConclusionsThis study suggests that the self-administered, video-guided STS test may be appropriate for participants of varying ages, body sizes, and activity levels, and is feasible for implementation within large, longitudinal studies. This video-guided test would also be useful for remote adaptation of the STS test during the COVID-19 pandemic.

Published: November 2021

Introduction
The wellbeing of sexual and gender minority (SGM) medical students and the impact of their experiences on career trajectory remain poorly understood. The present study aimed to characterize the incidence of mistreatment in SGM trainees as well as general perspectives on the acceptance of SGM individuals across medical and surgical specialties.

Methods
This was a cross sectional survey study of all actively enrolled medical students within the six University of California campuses conducted in March 2021. An online, survey tool captured incidence of bullying, discrimination, and suicidal ideation as well as perceived acceptance of SGM identities across specialties measured by slider scale. Differences between SGM and non-SGM respondents were assessed with two-tailed and chi-square tests. Qualitative responses were evaluated utilizing a multi-stage, cutting-and-sorting technique.

Results
Of approximately 3,205 students eligible for participation, 383 submitted completed surveys, representing a response rate of 12.0%. Of these respondents, 26.9% (n = 103) identified as a sexual or gender minority. Overall, SGM trainees reported higher slider scale scores when asked about being bullied by other students (20.0 vs. 13.9, P = 0.012) and contemplating suicide (14.8 vs. 8.8, P = 0.005). Compared to all other specialties, general surgery and surgical subspecialties had the lowest mean slider scale score (52.8) in perceived acceptance of SGM identities (All P < 0.001). In qualitative responses, students frequently cited lack of diversity as contributing to this perception. Additionally, 67.0% of SGM students had concerns that disclosure of identity would affect their future career with 18.5% planning to not disclose during the residency application process.

Conclusions
Overall, SGM respondents reported higher incidences of bullying and suicidal ideation as well as increased self-censorship stemming from concerns regarding career advancement, most prominently in surgery. To address such barriers, institutions must actively promote diversity in sexual preference and gender identity regardless of specialty.

ABSTRACT
Primary effusion lymphoma (PEL) is a rare AIDS-associated non-Hodgkin lymphoma, growing in the serous body cavities as a lymphomatous effusion. The endoscopic features of PEL can mimic Kaposi sarcoma (KS). We present a case where PEL presented as small intestinal masses which had a similar macroscopic appearance to KS. Endoscopic evaluation was used with biopsies which confirmed the diagnosis of PEL. PEL is a differential of gastrointestinal KS. Accurate diagnosis is crucial for prognostication in these patients. Our case emphasizes that PEL presenting as intestinal tumors can mimic KS macroscopically. Although treatment for PEL and KS includes standard chemotherapy with concurrent antiretroviral therapy, early detection of PEL can improve overall survival in these patients.

INTRODUCTION:
The genomic characterization of primary nonampullary duodenal adenocarcinoma indicates a genetic resemblance to gastric and colorectal cancers. However, a correlation between the clinical and molecular characteristics of these cancers has not been established. This study aimed to elucidate the clinicopathological features of sporadic nonampullary duodenal epithelial tumors, including their molecular characteristics and prognostic factors.

METHODS:
One hundred forty-eight patients with sporadic nonampullary duodenal epithelial tumors were examined in this study. Patient sex, age, TNM stage, tumor location, treatment methods, histology, KRAS mutation, BRAF mutation, Fusobacterium nucleatum, mucin phenotype, and programmed death-ligand 1 (PD-L1) status were evaluated. KRAS and BRAF mutations, Fusobacterium nucleatum, mucin phenotype, and PD-L1 status were analyzed by direct sequencing, quantitative polymerase chain reaction, and immunochemical staining.

RESULTS:
The median follow-up duration was 119.4 months. There were no deaths from duodenal adenoma (the primary disease). Kaplan-Meier analysis for duodenal adenocarcinoma showed a significant effect of TNM stage (P < 0.01). In univariate analysis of primary deaths from duodenal adenocarcinoma, TNM stage II or higher, undifferentiated, KRAS mutations, gastric phenotype, intestinal phenotype, and PD-L1 status were significant factors. In multivariate analysis, TNM stage II or higher (hazard ratio: 1.63 × 1010, 95% confidence interval: 18.66–6.69 × 1036) and KRAS mutation (hazard ratio: 3.49, confidence interval: 1.52–7.91) were significant factors.

DISCUSSION:
Only KRAS mutation was a significant prognostic factor in primary sporadic nonampullary duodenal adenocarcinoma in cases in which TNM stage was considered.

Published: November 2021

Abstract

Objectives
In ancient times Terminalia arjuna (Roxb.) Wight & Arn. (TA) was used for fast healing of fracture and to strengthen the bone. However, no scientific study has been done to validate its usefulness in the alleviation of osteoporosis. To investigate the efficacy of stem bark TA against post-menopausal osteoporosis using bilateral ovariectomized rat model.

Methods
Aqueous (TAA) and methanolic (TAM) extracts of TA was evaluated for its anti-osteoporotic activity. Sham control rats were allotted as Group I (Normal control); Group II animals acted as OVX control (Disease control); Group III OVX rats were treated with estrogen (Standard group – 2 mg/kg) Group IV and V OVX rats give treatment to TAA (250 and 500 mg/kg, p.o.), respectively. This treatment is continue for the four weeks and at the end, serum biochemical parameters such as serum calcium and alkaline phosphate were evaluated. Femoral bone parameters (Compression of vertebrae, femoral neck load testing, Three point bending of tibia, Femur length and weight), histology, body weight, and fifth lumbar vertebra breaking strength were also assessed after the sacrificing the animal.

Results
In OVX rats, atrophy of uterus and descent of BMD were suppressed by treatment with TAA and TAM. In addition, TAM 500 completely corrected the decreased serum concentration of Calcium, Phosphorus, ALP and TRAP observed in OVX rats. TAA and TAM both increased biomechanical strength significantly in comparison to the sham group. Histological results also revealed its protective action through elevation of bone formation. TAM significantly increase the uterine and femoral bone weight The TAM showed maximum anti-osteoporotic activity in in vivo study as compare to TAA.

Conclusions
The results, evaluated on the basis of biochemical, bone mineral density, biomechanical, and histopathological parameters, presented that TAA and TAM has a definite antiosteoporotic effect, like to estrogen, especially effective for inhibition bone fracture induced by estrogen deficiency.
