Objective: To measure spermatogenesis abnormalities in transwomen at the time of sex reassignment surgery (SRS) and to analyze the association between hormonal therapy duration and infertility severity.
Design: Retrospective study.
Setting: University hospital.
Patients: One-hundred seventy-three transwomen who underwent SRS from January 2000 to December 2015.
Interventions: All orchidectomy specimens were retrospectively reviewed and classified. History of hormonal therapy duration was retrieved from medical records.
Main Outcome Measures: Histological examinations of orchidectomy specimens were performed to assess spermatogenesis.
Results: One-hundred seventy-three orchidectomy specimens were evaluated. Histological examinations showed maturation arrest in 36.4%, hypospermatogenesis in 26%, Sertoli cell-only syndrome in 20.2%, normal spermatogenesis in 11%, and seminiferous tubule hyalinization in 6.4% of the specimens. Spermatogenesis abnormality severity was not associated with the total therapy duration ( = 0.81) or patient age at the time of surgery ( = 0.88). Testicular volumes and sizes were associated with spermatogenesis abnormality severity ( = 0.001 and = 0.026, right testicle and left testicle, resp.).
Conclusions: Feminizing hormonal treatment leads to reductions in testicular germ cell levels. All transwomen should be warned about this consequence, and gamete preservation should be offered before starting hormonal treatment.

B-type natriuretic peptide (BNP) levels accurately reflect the degree of cardiac overload in heart failure. Considering cardiac morphology and intracardiac pressure, including the left ventricular end-systolic volume index (LVESVI) and left ventricular end-diastolic volume index (LVEDVI), is essential for cardiac overload assessment. These indexes influence plasma BNP levels, and high heart rate is likely associated with cardiac morphology.

E-cigarette/vaping-associated lung injury (EVALI) is strongly associated with vitamin E acetate and often occurs with concomitant tetrahydrocannabinol (THC) use. To uncover pathways associated with EVALI, we examined cytokines, transcriptomic signatures, and lipidomic profiles in bronchoalveolar lavage fluid (BALF) from THC-EVALI patients. At a single center, we prospectively enrolled mechanically ventilated patients with EVALI from THC-containing products (N = 4) and patients with non-vaping acute lung injury and airway controls (N = 5).

Protein is essential for all living organisms; however, excessive protein intake can have adverse effects, such as hyperammonemia. Although mechanisms responding to protein deficiency are well-studied, there is a significant gap in our understanding of how organisms adaptively suppress excessive protein intake. In the present study, utilizing the fruit fly, Drosophila melanogaster, we discover that the peptide hormone CCHamide1 (CCHa1), secreted by enteroendocrine cells in response to a high-protein diet (HPD), is vital for suppressing overconsumption of protein.

Objectives: Triple negative breast cancer (TNBC) is a distinct subtype of breast cancer that has a poor prognosis due to the lack of effective therapeutic agents. Since a significant proportion of human surgical samples of TNBC expressed mRNA for the growth hormone (GH), growth hormone-releasing hormone (GHRH), and gonadotropin-releasing hormone (GnRH) receptors, and the mitogenic proliferative activity of GH, GHRH, and GnRH, have been identified as effective therapeutic targets for somatostatin and its analogs and GnRH analogs, Di Bella Method (DBM), a combination of hormonal analogs and vitamins, was introduced to target and inhibit solid tumors. The present study aimed to improve the prognosis of TNBC using DBM in women with TNBC.

Objectives: The aim of this study was to adapt and apply the Portuguese version of the Transgender Man Voice Questionnaire in a sample of Brazilian transgender men and to investigate the relationship between voice satisfaction and hormone therapy duration. In addition, we suggest reducing and reformulating the questionnaire for screening.
Methods: We conducted a cross-sectional study of 31 transgender men aged 18-50 years undergoing hormone therapy who answered a questionnaire adapted from the Transgender Woman Voice Questionnaire, validated in Portuguese.
