Taken together, these results suggest that KDM1A is a versatile regulator of enhancers and acts as a rheostat to maintain optimal enhancer activity by counterbalancing H3K4 methylation at enhancers.Sex cord stromal-tumors are rare tumors of the ovary that include numerous tumor subtypes of variable histological features and biological behavior. Surgery is the main therapeutic modality for the management of these tumors, while chemotherapy and hormonal therapy may be used in some patients with progressive and recurrent tumors. Several studies investigated molecular changes in the different tumor types. Understanding molecular changes underlying the development and progression of sex cord-stromal tumors provides valuable information for diagnostic and prognostic biomarkers and potential therapeutic targets for these tumors. In this review, we provide an update on the clinical presentation, molecular changes, and management of sex cord-stromal tumors.
To assess the independent causal effect of BMI and type 2 diabetes (T2D) on socioeconomic outcomes by applying two-sample Mendelian randomization (MR) analysis.

We performed univariable and multivariable two-sample MR to jointly assess the effect of BMI and T2D on socioeconomic outcomes. We used overlapping genome-wide significant single nucleotide polymorphisms for BMI and T2D as instrumental variables. Their causal impact on household income and regional deprivation was assessed using summary-level data from the UK Biobank.

In the univariable analysis, higher BMI was related to lower income (marginal effect of 1-SD increase in BMI [β = -0.092; 95% CI -0.138; -0.047]) and higher deprivation (β = 0.051; 95% CI 0.022; 0.079). In the multivariable MR, the effect of BMI controlling for diabetes was slightly lower for income and deprivation. Diabetes was not associated with these outcomes.

High BMI, but not diabetes, shows a causal link with socioeconomic outcomes.

The Indian government announced a nationwide lockdown as a preventive measure to control the prevailing COVID-19 pandemic. This survey was developed and conducted to assess the impact of lockdown on Indian optometry practice.

A survey questionnaire was designed and circulated across the optometrists practicing in India through multiple social media platforms. All the data were extracted and only valid response were analyzed and reported.

A total of 691 optometrists participated in the survey. Most of the participants (22.25%) were in private practice followed by academics (14.89%). Among the valid responses collected, it was found that 43.37% of the respondents were consulting patients during the lockdown. Of these, 27.17% of optometrists were examining infectious cases and 48.68% were examining all the patients who came for consultation. Approximately 50.94% of the participated optometrist had begun telephonic/e‑mail/video consultations. In addition, 64.48% reported that optometrists were at an equal risk of clinching COVID‑19 on comparison with other domains during patient examination. Nearly 30.44% respondents felt that optometrists would face challenges in approaching the patient post COVID-19 considering the close working distance.

A proportion of optometrist have switched to some form of teleconsultation in order to aid patients during this prevailing pandemic. Regulatory bodies should issue appropriate guidelines regarding the safe optometry practice for the betterment of both patient and practitioners during face-to-face consultation.

Human experimental evidence complemented by observational studies suggests that THC may have psychotogenic effects while CBD may have antipsychotic effects. However, whether their effects on brain function are consistent with their opposing behavioral effects remains unclear. To address this, here we synthesize neuroimaging evidence investigating the acute effects of THC and CBD on human brain function using a range of neuroimaging techniques, with an aim to identify the key brain substrates where THC and CBD have opposing effects. After a systematic search, a review of the available studies indicated marked heterogeneity. However, an overall pattern of opposite effect profiles of the two cannabinoids was evident with some degree of consistency, primarily attributed to the head-to-head challenge studies of THC and CBD. While head-to-head comparisons are relatively few, collectively the evidence suggests that opposite effects of THC and CBD may be present in the striatum, parahippocampus, anterior cingulate/medial prefrontal cortex, and amygdala, with opposite effects less consistently identified in other regions. Broadly, THC seems to increase brain activation and blood flow, whereas CBD seems to decrease brain activation and blood flow. Given the sparse evidence, there is a particular need to understand the mechanisms underlying their opposite behavioral effects because it may not only offer insights into the underlying pathophysiological mechanisms of psychotic disorders but also suggest potentially novel targets and biomarkers for drug discovery.
The COVID-19 pandemic has led to the confinement of approximately one third of the world population, causing a drastic change in the activities of daily life with many repercussions at the health, economic and social levels.

The objective of the present work is to present the epidemiological variations in the production of fractures in the period of mandatory confinement in our reference population.

Analytical retrospective comparative study of two groups of patients Group A patients admitted before the state of alarm that forced confinement in the period from January 13 to March 13 compared to Group B patients admitted in the two months of confinement, until the de-escalation period began, March 13-May 13. Epidemiological variables including age, personal history, type of fracture, mechanism of injury, outpatient rate, and hospital stay were recorded.

A total of 190 patients were included. 112 in the pre-confinement period and 78 in the confinement (30% decrease). The mean age (p = 0.007) and falls aase in the average postoperative and overall stay has been observed.
Congenital knee dislocation is a very rare entity, characterised by deformity in knee recurvatum present at birth, and there is currently no consensus on the optimal treatment. The aim of the present study is to analyse the functional results and long-term complications after the application of a protocol of therapeutic action for the management of congenital knee dislocation (CKD) created in a reference centre for child orthopaedics.

Retrospective descriptive study of patients with congenital dislocation of the knee who followed CRPL between January 1997 and December 2010. Demographic variables, type of treatment, functional outcomes at the end of the follow-up, complications and relapses were studied. The conservative treatment consisted of serial casts, leaving the surgical treatment for cases in which passive flexion was not achieved above 30° or the conservative treatment failed.

9 patients (11 knees) met the inclusion criteria. The 66.7% were girls and the average follow-up was 15 years (9-22). In all cases, conservative treatment was initiated. Of the 11 knees treated, less than half (36%) required surgery. The average Lysholm questionnaire was 90.3 points, the WOMAC pain 0.4 (0-1), WOMAC stiffness 1.8 (0-6) and WOMAC function 3.8 (1-12).

The existence and application of the PLCR protocol in a pathology as rare as congenital knee dislocation suggests good long-term functional results with few complications and no recurrences.

Roux-en-Y gastric bypass is a proven treatment for morbid obesity and its sequelae. Gastric bypass has a safe risk profile, but postoperative complications can be seen. We report on 10 cases of postoperative bleeding causing an obstructing clot at the jejunojejunostomy (JJ) occurring over a 9-year period.

The aim was to document presenting symptoms of obstructing clots at the JJ and to suggest a treatment approach to minimize complications.

University Hospital, United States METHODS The local Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was queried for all patients undergoing reoperation after Roux-en-Y gastric bypass, from July 2009 until December 2019. All patients who were found to have postoperative bleeding causing an obstructing clot at the JJ were selected for retrospective medical-record review.

The most common presenting symptoms were Hematocrit drop (10 of 10), nausea (9 of 10), abdominal pain (7 of 10), and hematemesis (4 of 10). There weron and reoperation, there is a risk for serious complications. Typical presenting symptoms include nausea and abdominal pain, which help differentiate it from other causes of decreased hematocrit. Diagnosis is commonly made with computerized tomographic (CT) scan. Decompression of a dilated remnant stomach before addressing the clot can prevent intraperitoneal spillage and subsequent abscess formation. Enterotomy creation and removal of clot is recommended, without fear of continued bleeding.
Necrotizing fasciitis (NF) is a rapid infectious process involving the fascia and subcutaneous tissue. Current standards of care rely on surgical debridement, resulting in large defects, with limited reconstructive options. Wound management has evolved over the last decade, including use of bilayer wound matrices (BWM). The authors sought to assess the use of collagen-GAG bilayer wound matrices on STSG take for NF wounds.

A qualitative clinical evaluation (2016-2018) was performed to analyze the efficacy of BWM to aide in STSG take. Primary outcomes were 180-day bilayer matrix success, defined by progressing to split-thickness skin graft (STSG) and STSG take, determined by clinical evaluation. Wounds without a diagnosis of NF or reconstruction with BWM were excluded.

Ten patients with 11 NF wounds were identified. Average BMI was 32 kg/m
. Comorbidities included hypertension (70%), diabetes (40%), and peripheral vascular disease (40%). Average wound size was 542cm
(range 49cm
-1050cm
) and average wound age was 19 days at BWM placement. click here Matrices were applied to the lower extremity (64%), upper extremity (27%), and perineum (9%). One-hundred percent (n = 11) of wounds were deemed successful by receiving a STSG. Average time to STSG was 44 days (21d -108d). Complications consisted of delayed healing (n = 1, 8%) and partial necrosis (n = 1). No instances of infection or STSG graft loss occurred.

Complex defects caused by soft tissue necrotizing infections remain a reconstructive challenge. We highlight the benefit of a BWM as a treatment modality for reconstruction by priming the wound bed for a definitive STSG.
