BACKGROUND: Acne often worsens in transmasculine patients who are on prolonged testosterone therapy. Isotretinoin is an oral retinoid used in the treatment of severe or refractory cases of acne, but it has the potential to cause delayed wound healing. Transmasculine patients may potentially be prescribed treatment for acne with isotretinoin while also planning to undergo chest masculinization surgery. OBJECTIVE: This scoping review aims to determine whether isotretinoin has a negative impact on postoperative healing in transmasculine patients undergoing chest masculinization surgery...

Three series of compounds were prioritized from a high content screening campaign that identified molecules that blocked dihydrotestosterone (DHT) induced formation of Androgen Receptor (AR) protein-protein interactions (PPIs) with the Transcriptional Intermediary Factor 2 (TIF2) coactivator and also disrupted preformed AR-TIF2 PPI complexes; the hydrobenzo-oxazepins (S1), thiadiazol-5-piperidine-carboxamides (S2), and phenyl-methyl-indoles (S3). Compounds from these series inhibited AR PPIs with TIF2 and SRC-1, another p160 coactivator, in mammalian 2-hybrid assays and blocked transcriptional activation in reporter assays driven by full length AR or AR-V7 splice variants...

Endo-lysosomes transport along microtubules and clustering in the perinuclear area are two necessary steps for microbes to activate specialized phagocyte functions. We report that RUN and FYVE domain-containing protein 3 (RUFY3) exists as two alternative isoforms distinguishable by the presence of a C-terminal FYVE domain and by their affinity for phosphatidylinositol 3-phosphate on endosomal membranes. The FYVE domain-bearing isoform (iRUFY3) is preferentially expressed in primary immune cells and up-regulated upon activation by microbes and Interferons...

Number sense, the ability to decipher quantity, forms the foundation for mathematical cognition. How number sense emerges with learning is, however, not known. Here we use a biologically-inspired neural architecture comprising cortical layers V1, V2, V3, and intraparietal sulcus (IPS) to investigate how neural representations change with numerosity training. Learning dramatically reorganized neuronal tuning properties at both the single unit and population levels, resulting in the emergence of sharply-tuned representations of numerosity in the IPS layer...

UNLABELLED: Disordered eating-related attitudes are a leading cause of energy deficiency and menstrual disturbances in exercising women. Although treatment recommendations include psychological counseling with increases in dietary intake, a key concern is whether increased dietary intake may exacerbate negative eating behaviors. OBJECTIVE: To determine the effects of a 12-month nutritional intervention on eating-related attitudes and psychological characteristics in exercising women with oligomenorrhea/amenorrhea (Oligo/Amen)...

PURPOSE: Hypoestrogenism triggers increased production of inflammatory mediators, which contribute to bone loss during postmenopausal osteoporosis. This study aimed to investigate the association between circulating inflammatory markers and bone outcomes in postmenopausal women. MATERIALS AND METHODS: We conducted a cross-sectional, secondary analysis of baseline data from participants who completed a 12-month randomized controlled trial, The Prune Study (NCT02822378), which included healthy postmenopausal women (n=183, 55-75 years old) with bone mineral density (BMD) T-score between 0...

The prevalence of osteoporosis among women aged 50 y and older is expected to reach 13.6 million by 2030. Alternative nonpharmaceutical agents for osteoporosis, including nutritional interventions, are becoming increasingly popular. Prunes (dried plums; Prunus domestica L.) have been studied as a potential whole-food dietary intervention to mitigate bone loss in preclinical models of osteoporosis and in osteopenic postmenopausal women. Sixteen preclinical studies using in vivo rodent models of osteopenia or osteoporosis have established that dietary supplementation with prunes confers osteoprotective effects both by preventing and reversing bone loss...

INTRODUCTION: We aimed to compare short term outcomes after robot assisted radical cystectomy (RARC) and open radical cystectomy (ORC) for urinary bladder cancer in a large population. MATERIALS AND METHODS: We included all patients without distant metastases who underwent either RARC or ORC with ileal conduit between 2011 and 2019 registered in the Bladder cancer data Base Sweden (BladderBaSe) 2.0. Primary outcome was unplanned readmissions within 90 days, and secondary outcomes within 90 days of surgery were reoperations, Clavien 3-5 complications, total days alive and out of hospital, and mortality...

BACKGROUND: Intravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from urothelial cancer and all causes was investigated as secondary outcomes. METHODS: We investigated a population-based cohort of 1038 consecutive patients subjected to radical surgery for UTUC 2015-2019 in Sweden, using the Bladder Cancer Data Base Sweden (BladderBaSe 2...

BACKGROUND: We sought to develop a novel strategy for expanding an existing HIV partner services (PS) model to provide comprehensive sexual health services, including: STI testing, a virtual telemedicine visit, and access to immediate start medication (ART, PEP, or PrEP). Fast Track was an NIH-funded implementation science trial in New York City to pilot and refine the new strategy, and examine its feasibility, acceptability, and impact. METHODS: Over the course of one year, health department staff collaborated with the academic research team to develop Fast Track protocols and workflows, create a cloud-based database to interview and track patients, and train disease intervention specialists (DIS) to deliver the new program...

Diatoms in the Pseudo-nitzschia genus produce the neurotoxin domoic acid. Domoic acid bioaccumulates in shellfish, causing illness in humans and marine animals upon ingestion. In 2017, high domoic acid levels in shellfish meat closed shellfish harvest in Narragansett Bay, Rhode Island for the first and only time in history, although abundant Pseudo-nitzschia have been observed for over 60 years . To investigate whether an environmental factor altered endemic Pseudo-nitzschia physiology or new domoic acid-producing strain(s) were introduced to Narragansett Bay, we conducted weekly sampling from 2017 to 2019 and compared closure samples...

PURPOSE: We constructed Bladder Cancer Data Base Sweden (BladderBaSe) 2.0 to expand studies in BladderBaSe on incidence, treatment outcomes, side effects, survival and health economic aspects of men and women with cancer in the urinary bladder, upper tract urothelial carcinoma (UTUC) (renal pelvis and ureter) and urethral carcinoma. PARTICIPANTS: BladderBaSe 2.0 includes 53 298 patients with cancer in the urinary bladder, diagnosed from 1 January 1997 to 31 December 2019, and 961 patients with UTUC in the renal pelvis and 792 in the ureter, and 146 patients with urethral urothelial carcinoma, diagnosed from 1 January 2015 to 31 December 2019, and in total 275 816 participants in reference groups, free of cancer in the urinary tract, matched 1:5 on sex, age and county...

BACKGROUND: Previous research has associated repeated transurethral procedures after a diagnosis of non-muscle invasive bladder cancer (NMIBC) with increased risk of death of causes other than bladder cancer. AIM: We investigated the overall and disease-specific risk of death in patients with NMIBC compared to a background population sample. METHODS: We utilized the database BladderBaSe 2.0 containing tumor-specific, health-related and socio-demographic information for 38,547 patients with NMIBC not primarily treated with radical cystectomy and 192,733 individuals in a comparison cohort, matched on age, gender, and county of residence...

Diet plays a role in the pathophysiology and treatment of women with hyperandrogenic menstrual disturbances; however, limited research exists examining components of dietary intake in women with subclinical menstrual disturbances. The aim of this investigation was to evaluate the relationship between diet quality and hormonal status in exercising women with menstrual disturbances. Eighty exercising women with ovulatory menstrual cycles (OV; n=32), women with oligo/amenorrhea without evidence of hyperandrogenism (Oligo/Amen-LowFAI n=28), and women with oligo/amenorrhea and evidence of subclinical hyperandrogenism (Oligo/Amen-HighFAI; n=32) participated in the cross-sectional observational study (Clinical Trial Number NCT00392873)...

BACKGROUND: Medication Regimen Complexity (MRC) refers to the combination of medication classes, dosages, and frequencies. The objective of this study was to examine the relationship between the scores of different MRC tools and the clinical outcomes. METHODS: We conducted a retrospective cohort study at Roger William Medical Center, Providence, Rhode Island, which included 317 adult patients admitted to the intensive care unit (ICU) between 1 February 2020 and 30 August 2020...

BACKGROUND Gastric heterotopia is a benign entity found throughout the gastrointestinal tract but is rarely identified in the rectum. Since 1939, only 94 cases have ever been identified, and it can present as a mass formation with symptomatology that mimics colorectal malignancy. In some instances, malignancy has been shown to arise within rectal gastric heterotopia. Here, we present 3 cases from the past 20-year period of rectal gastric heterotopia at a single tertiary institution. CASE REPORT A 25-year-old man (case 1), a 58-year-old woman (case 2), and a 33-year-old man (case 3) were found to have polypoid mass-like lesions greater than 1...

Field studies conducted over time to collect any type of plant response to a set of treatments are often not treated as repeated measures data. The most used approaches for statistical analyses of this type of longitudinal data are based on separate analyses such as ANOVA, regression, or time contrasts. In many instances, during the review of manuscripts, reviewers have asked researchers to treat year, for example, as a random effect and ignore the interactions between year and other main effects. One drawback of this approach is that the correlation between measurements taken on the same subject over time is ignored...

BACKGROUND: Dietary consumption of prunes has favorable impacts on bone health, but more research is necessary to improve upon study designs and refine our understandings. OBJECTIVES: We evaluated the effects of prunes (50 g or 100 g/d) on bone mineral density (BMD) in postmenopausal women during a 12-mo dietary intervention. Secondary outcomes include effects on bone biomarkers. METHODS: The single-center, parallel-arm 12-mo randomized controlled trial tested the effects of 50 g and 100 g prunes compared with a control group on BMD (every 6 mo) and bone biomarkers in postmenopausal women...

The use of non-pharmacological alternatives to pharmacological interventions, e.g., nutritional therapy, to improve or maintain bone mineral density (BMD) in postmenopausal women has gained traction over the past decade, but limited data exist regarding its efficacy. This paper describes the design of the Prune Study, a randomized controlled trial (RCT) that explored the effectiveness of a 12-month intervention of daily prune consumption on bone density, bone structure and strength estimates, bone turnover, various biomarkers of immune function, inflammation, and cardiovascular health, as well as phenolic and gut microbiota analyses...
