This study investigated whether rs1784692 is a risk factor for polycystic ovary syndrome (PCOS) in Han Chinese women.
A case-control study was conducted in Han Chinese women, involving 526 PCOS patients and 522 control participants. A TaqMan MGB probe assay was used to genotype the variant rs1784692. Dominant and additive models were employed for genotype-phenotype association analysis in the PCOS and control samples.
The minor allele C of rs1784692 is protective against PCOS (odds ratio [OR] 0.556, 95% confidence interval [CI] 0.408-0.759, P = 1.83×10
), even after adjustment for body mass index (BMI) and age (OR
0.539, 95% CI 0.391-0.743, P
=1.62×10
). Genotype-phenotype analysis of the dominant model showed that mean BMI in the CC+CT group was higher than in the TT group in the PCOS group (27.12±5.82 versus 24.57±4.52, P=1.0×10
), but not in the control groups, indicating that the minor allele C of rs1784692 associates with BMI in women with PCOS. The mean LH (luteinizing hormone) concentration in the CC+CT group was lower than in the TT group in PCOS and control participants (9.33±5.08 versus 10.93±5.91, P = 0.036; 4.39±1.66 versus 4.89±2.07, P = 0.021). Genotype-phenotype analysis of additive model showed that mean BMI in TC group was higher than in the TT group in PCOS patients compared with control participants (27.14±5.81 versus 24.57±4.52, P = 3.06×10
).
The SNP rs1784692 in gene ZBTB16 is protective against PCOS but is associated with increased BMI in Han Chinese women with PCOS.

This has not been the case with the diagnosis of primary bone and soft tissue lesions. FNA has been an important part of our orthopaedic oncology practice for 18 years. Our ability to efficiently and effectively care for patients dramatically improved when FNA became an option for obtaining a tissue diagnosis. We discuss the advantages and disadvantages of a pathologist-driven FNA service in orthopaedic oncology.
To evaluate the incidence, risk of malignancy, and management of "suspicious for malignancy" (SFM) for non-papillary carcinoma diagnoses according to The Bethesda System for Reporting Thyroid Cytopathology (TBSRTC).
A retrospective search was performed for all thyroid fine-needle aspirations (FNAs) with an SFM diagnosis in the electronic Pathology database at The Johns Hopkins Hospital from 2000 to 2019. During this period, a total of 644 cases were diagnosed as SFM. Futibatinib Of these, 55 cases of "suspicious for non-papillary thyroid carcinoma" (SNPTC) were identified. These 55 cases were then compared with 65 random cases of "suspicious for papillary thyroid carcinomas" (SPTC) diagnoses as a control group.
The SNPTC subgroup consisted of 28 cases of "suspicious for medullary thyroid carcinoma" (SMTC) (50.91%), 4 cases of "suspicious for metastasis" (SMET) (7.27%), 3 cases of "suspicious for malignant lymphoma" (SML) (5.45%), 2 cases of "suspicious for poorly-differentiated thyroid carcinoma" (SPDC) (3.64%), anistory, in addition to cytomorphology, was helpful when rendering the diagnosis of SNPTC.
In response to ongoing concerns regarding transmission of the novel coronavirus (COVID-19), surgical practice has changed for the foreseeable future. Practice guidelines recommend only urgent or emergent surgical procedures be performed to minimize viral transmission. This effectively limits standard training and practice for surgical residents. The purpose of this article is to describe opportunities in surgical simulation, and highlights the challenges associated with training in the COVID-19 era.
This is a perspective summarizing the potential role of surgical simulation to target training gaps caused by decreased surgical caseloads.
This manuscript concisely discusses simulation options available to training programs, including the novel concept of "surgical kits." These kits include all instruments necessary to simulate a procedure at home, effectively pairing safety and utility.

Mental skills training (MST) in surgical education varies greatly in quality and outcomes. This systematic review assessed the effectiveness of MST on surgical trainee performance in simulated and operating room (OR) settings.
We searched PubMed/MEDLINE, EMBASE, and PsycINFO for randomized controlled trials using Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Peer-reviewed studies published in the English language between January 1, 2000 and March 1, 2020 were considered for inclusion. Articles that did not study surgical residents, assess surgical performance as an outcome, or report findings were excluded. Study characteristics, methodologies, and outcomes were qualitatively analyzed. Grading of Recommendations, Assessment, Development and Evaluations (GRADE) was used to measure the quality of the studies, and the Oxford quality scoring system for risk of bias ratings.
Seven randomized controlled trials met study inclusion criteria; interventions were mental practice, relaxation exercises, action observation, and Mindfulness-Based Stress Reduction. Targeted interventions based on mental practice, relaxation exercises, and MBSR significantly improved surgical performance in four (57%) studies. Risk of bias was low for all included studies, and quality of evidence was moderate for both simulated and OR performance.
Mental practice, relaxation, and mindfulness training improved simulation and OR performance for surgical residents. There was insufficient evidence to support other MST interventions or the intermediate- and long-term efficacy of MST.
