Gender-affirming hormone therapy: effects on cardiovascular risk and vascular function.

Background: Gender-affirming hormone therapy (GAHT) is used in individuals with gender identity dysphoria to align an individual's secondary sexual characteristics with their affirmed gender. We conducted a systematic review of the literature to explore the mechanisms regarding the effects of GAHT on the vasculature.

Methods: A literature search using PUBMED, Embase, Scopus and Lilacs was performed using search terms for GAHT, cardiovascular disease (CVD) risk and transgender.

Adaptations of cognitive remediation therapy for adolescents with anorexia nervosa for delivery via telehealth.

Objective: The COVID-19 pandemic hastened a transition to treatment delivery via telehealth. While barriers still exist, the increased uptake of telehealth has the potential to increase access to mental health treatment for all diagnoses, including eating disorders. Delivery of evidence-based treatment as well as adjunctive treatments, including those that are hard to find in-person, have been modified to virtual format to increase accessibility and allow for continuity of care for adolescents with anorexia nervosa.

Hurricane effects, mitigation, and preparedness in the Caribbean: Perspectives on high importance-low prevalence practices from agricultural advisors.

Frequent hurricanes affect agricultural productivity, food security, economic security, and human wellbeing in the Caribbean islands. We assessed recent hurricane effects on the agricultural sector, and the challenges faced by farmers, foresters, and advisors related to hurricane preparedness and recovery in Puerto Rico and US Virgin Islands (USVI). We used qualitative and quantitative survey methods to compile perspectives from agricultural advisors related to hurricane effects on farmlands, preparedness and recovery measures taken by land managers, and the needs regarding preparing for and responding to future hurricanes.

Characterization of a "low-risk" cohort of grade group 2 prostate cancer patients: Results from the Shared Equal Access Regional Cancer Hospital database.

Objectives: To examine if there is a subset of men with grade group 2 prostate cancer who could be potential candidates for active surveillance.

Methods: We used the Shared Equal Access Regional Cancer Hospital database to identify 776 men undergoing radical prostatectomy from 2006 to 2015 with >8 biopsy cores obtained and complete information. We compared men who fulfilled low-risk disease criteria (clinical stage T1c/T2a; grade group 1; prostate-specific antigen ≤10 ng/mL) with the exception of grade group 2 versus men who met all three low-risk criteria.

Targeted Exome Sequencing of the Cancer Genome in Patients with Very High-risk Bladder Cancer.

Unlabelled: We completed targeted exome sequencing of the tumors of 50 patients with pTis-pT4b bladder cancer. Mutations were categorized by type, stratified against previously identified cancer loci in the Catalogue of Somatic Mutations in Cancer and The Cancer Genome Atlas databases, and evaluated in pathway analysis and comutation plots. We analyzed mutation associations with receipt of neoadjuvant chemotherapy, nodal involvement, metastatic disease development, and survival.

Prostate cancer in men of African origin.

Men of African origin are disproportionately affected by prostate cancer: prostate cancer incidence is highest among men of African origin in the USA, prostate cancer mortality is highest among men of African origin in the Caribbean, and tumour stage and grade at diagnosis are highest among men in sub-Saharan Africa. Socioeconomic, educational, cultural, and genetic factors, as well as variations in care delivery and treatment selection, contribute to this cancer disparity. Emerging data on single-nucleotide-polymorphism patterns, epigenetic changes, and variations in fusion-gene products among men of African origin add to the understanding of genetic differences underlying this disease.

Utilization and impact of surgical technique on the performance of pelvic lymph node dissection at radical prostatectomy: Results from the Shared Equal Access Regional Cancer Hospital database.

Objective: To evaluate performance of pelvic lymph node dissection during radical prostatectomy within an equal access care setting over a period of time, and stratified by prostate cancer risk group and surgical technique.

Methods: We identified men in the Shared Equal Access Regional Cancer Hospital database who had open or robotic-assisted radical prostatectomy from 2006 to 2013. Univariable logistic regression was used to test the association between age, race, body mass index, total biopsy cores, number of positive biopsy cores, risk group, year, center, surgical volume and surgical technique on pelvic lymph node dissection use.

Impact of the US Preventive Services Task Force Grade D Recommendation: Assessment of Evaluations for Elevated Prostate-specific Antigen and Prostate Biopsies in a Large Urology Group Practice Following Statement Revision.

On October 7, 2011, the United States Preventive Services Task Force (USPSTF) released their evidence statement and grade D recommendation against prostate-specific antigen (PSA)-based prostate cancer screening. Using a time series design, we assessed the effect of this recommendation upon evaluations for elevated PSA levels and prostate biopsies in our large urology group practice. We found that, despite a 24.

Clinicopathological characteristics and outcomes of surgically excised renal masses in African Americans.

Objectives: In the present study, we report on the clinical and pathological characteristics of African American (AA) patients with surgically excised renal masses and assess the associations between race and oncological outcomes.

Methods And Materials: We conducted a retrospective review of patients who underwent partial or radical nephrectomy for renal masses at our institution between 2000 and 2010. Patients were divided into 2 groups based on self-reported race: AA and non-AA.

Human papillomavirus testing in men.

Despite the morbidity associated with anogenital condylomas and the mortality associated with anal, penile, and cervical carcinoma as a direct consequence of human papillomavirus (HPV), the US Centers for Disease Control and Prevention currently does not recommend routine screening for HPV in immuno competent men. However, findings of emerging research focusing on the high-risk populations of men who have sex with men and men who test positive for human immunodeficiency virus, in whom HPV infection is pervasive and persistent, suggest that these populations may benefit from screening. Therefore, HPV screening, including anal cytology, should be considered for these men in settings where appropriate follow-up, including high-resolution anoscopy, is available.

Heterodimerization of the alpha and beta isoforms of the human thromboxane receptor enhances isoprostane signaling.

Isoprostanes are free radical catalyzed products of arachidonic acid that are elevated in pro-oxidant disease states. Two isoprostanes, 8-isoprostaglandin F(2alpha) (iPF(2alpha)III) and 8-isoprostaglandin E2 (iPE2III), act at the receptor for thromboxane A2 (the TP) to mediate pro-atherogenic effects in vivo. We confirmed dimerization of the human TP isoforms, TPalpha and TPbeta, and determined the impact on isoprostane signaling.

Cutaneous microenvironment of human immunodeficiency virus (HIV)-seropositive and HIV-seronegative individuals, with special reference to Staphylococcus aureus colonization.

A cross-sectional quantitative study of cutaneous bacterial and yeast flora at seven body sites in 99 human immunodeficiency virus-seropositive and 50 seronegative military personnel was performed. Statistically significant differences in carriage rates were only observed for Staphylococcus aureus on the foreheads of seropositive individuals. Seronegative individuals demonstrated staphylococcal carriage rates 1.

Propionibacterium acnes colonization in acne and nonacne.

Propionibacterium acnes is a number of the resident bacterial flora and resides in sebaceous follicles. Age-related and body-dependent quantitative differences exist, indicating the role of sebum as an important ecological factor for P. acnes.

Cutaneous leiomyomas lack estrogen and progesterone receptor immunoreactivity.

Gonadotropin-releasing hormone analog therapy is useful in treating uterine and some extrauterine smooth muscle tumors. These smooth muscle tumors have been demonstrated to have estrogen receptor and progesterone receptor immunoreactivity. The estrogen receptor and progesterone receptor immunoreactivity of smooth muscle tumors of the skin has not been reported.

Anticytokeratin antibody 34 beta E12 staining in prostate carcinoma.

Anticytokeratin antibody 34 beta E12 is advocated as an immunohistochemical stain for discriminating benign and malignant lesions of the prostate. Positive staining with 34 beta E12 is said to identify benign lesions, whereas negative staining is said to help substantiate a diagnosis of carcinoma. It is further claimed that 34 beta E12 does not stain prostate carcinoma.

Does oral isotretinoin prevent Propionibacterium acnes resistance?

Oral and topical antibiotics play a major role in acne therapy. Physicians base treatment choices on personal perceptions of efficacy, cost-effectiveness or risk-benefit ratios and rarely take bacterial resistance into account. Propionibacterium acnes isolates resistant to one or more anti-acne antibiotics have been reported in Europe, the USA, Japan and New Zealand.

A new method for in vivo evaluation of antimicrobial agents by translocation of complex dense populations of cutaneous bacteria.

Previously, we described methods for measuring in vivo antimicrobial activity in which the resident bacterial flora of the forearm is expanded by occlusion with an impermeable plastic film, test agents are applied and quantitative cultures are obtained at varying time points. This methodology allows for an in vivo quantitative assessment of antimicrobial effects directed against a dense flora comprised primarily of staphylococci. This method may not be applicable to situations in which there is a high density of multiple species of bacteria.

The role of extracellular polysaccharide substance produced by Staphylococcus epidermidis in miliaria.

Background: Previous studies have indicated that cutaneous bacteria, particularly coagulase-negative staphylococci, play a role in the pathogenesis of miliaria. An accumulation of periodic acid-Schiff (PAS)-positive material has been described as blocking the sweat duct in miliaria. Furthermore, a PAS-positive extracellular polysaccharide substance (EPS) has been identified as a product of some strains of Staphylococcus epidermidis.

Primary angiosarcoma of the spleen: a case report and review of the literature.

We describe a 47-year-old man with shoulder pain, multiple bony lesions, and a 1-cm lesion in the spleen. T-1 facetectomy revealed a poorly differentiated malignant neoplasm. Several months after chemotherapy, multiple splenic lesions were found by computed tomography and liver-spleen scan.

Semiquantitative study of tinea capitis and the asymptomatic carrier state in inner-city school children.

Objective: To quantify and characterize the asymptomatic carrier state of tinea capitis in school children from the inner city.

Methods: All students attending a parochial school (kindergarten through seventh grade) in the city of Philadelphia were cultured for tinea capitis periodically over 16 months (1404 hemi-scalp cultures from 224 children).

Results: Our initial prevalence study of this all-black population (ages 5 to 13 years) found a 3% rate of index cases (symptomatic) and a 14% rate of asymptomatic carriers (without black-dot lesions, obvious hair loss, scaling, crusts, pustules, or erythema).

Treatment of kerions.

Therapy for kerions was evaluated by randomly assigning 30 patients to one of four treatment groups: group A griseofulvin, group B griseofulvin plus erythromycin, group C griseofulvin plus prednisone, and group D griseofulvin, erythromycin, and prednisone. Data indicate that antibiotic and steroid therapy, in addition to griseofulvin, may reduce scaling and pruritus, but does not reduce the time it takes for kerions to flatten.

Microbiology of kerions.

Qualitative and semiquantitative bacterial culture specimens were obtained from 44 patients with kerions. Staphylococcus aureus was isolated from the scalp surface overlying the kerion in 29% of patients and from the pus within the kerion in 48% of patients. Gram-negative bacteria were found in the same locations in 11.

A study of the efficacy of antimicrobial detergents for hand washing: using the full-hand touch plates method.

We studied the effects of four kinds of antimicrobial detergents, 4% chlorhexidine gluconate (CHG), chlorbenzarconium (CBC), 10% povidone-iodine (PVI), 0.3% triclosan (TRI), and one non-medicated detergent (NMD) using the full-hand touch plates method. Before and after 3 minutes of hand scrubbing with a brush, bacterial colonies on the hand surface and subungual bacteria were counted.

An investigation of human apocrine gland secretion for axillary odor precursors.

Recently completed studies from our laboratories have demonstrated that the characteristic human male axillary odors consist of C6 to C11 normal, branched, and unsaturated aliphatic acids, with (E)-3-methyl-2-hexenoic acid being the most abundant. To investigate the mechanism by which the odor is formed, it is necessary to determine the nature of the odorless precursor(s) found in the apocrine secretion which is converted by the cutaneous microorganisms to the characteristic axillary odor. Pooled apocrine secretion was obtained from several male volunteers by intracutaneous injection of epinephrine.
