Methods: VRC07523LS, 80 mg/dose, was administered subcutaneously after birth to non-breastfed (Cohort 1; N=11, enrolled in USA) and breastfed (Cohort 2; N=11, enrolled in South Africa and Zimbabwe) infants exposed to HIV-1.

Recent Advances in the Genetics of Ataxias: An Update on Novel Autosomal Dominant Repeat Expansions.

Purpose Of Review: Autosomal dominant cerebellar ataxias, also known as spinocerebellar ataxias (SCAs), are genetically and clinically diverse neurodegenerative disorders characterized by progressive cerebellar dysfunction. Despite advances in sequencing technologies, a large proportion of patients with SCA still lack a definitive genetic diagnosis. The advent of advanced bioinformatic tools and emerging genomics technologies, such as long-read sequencing, offers an unparalleled opportunity to close the diagnostic gap for hereditary ataxias.

Quantification of the Anterior-Centripetal Movement of the Ciliary Muscle During Accommodation Using Dynamic OCT Imaging.

Purpose: Although the lens undoubtedly plays a major role in presbyopia, altered lens function could be in part secondary to age-related changes of the ciliary muscle. Ciliary muscle changes with accommodation have been quantified using optical coherence tomography, but so far these studies have been limited to quantifying changes in ciliary muscle thickness, mostly at static accommodative states. Quantifying ciliary muscle thickness changes does not effectively capture the dynamic anterior-centripetal movement of the ciliary muscle during accommodation.

Fertility preservation in cancer patients: Data collection, analysis, and continuous improvement of cryostorage.

Data collection from all referred patients allows continuous learning and improvement of services. Patient safety and return for cancer therapy takes priority in all oncofertility services. In certain cases, the intervention for female patients is contraindicated and, aside from extensive counseling, alternative methods of preserving fertility should be explored.

Sustanon suppresses spermatogenesis and increases cell death.

Background: Anabolic-androgenic steroids (AAS) are synthetic derivatives of testosterone. Sustanon, dissolved in peanut oil, is an AAS used by athletes to build muscle mass. This study aims to examine the effects of Sustanon on male reproductive health.

Exploring Denosumab in the Treatment of Giant Cell Tumors: Clinical Evidence and Controversies.

Giant cell tumors (GCTs) are benign but locally aggressive bone neoplasms that primarily affect skeletally mature individuals. They are characterized by a tendency for recurrence and being associated with significant morbidity. Traditional treatment has focused on surgical resection; however, the role of medical therapies, such as Denosumab, a bone anti-resorptive drug, which has been Food and Drug Administration (FDA)-approved for unresectable GCTs since 2013, recently has gained prominence.

Assessing Clinical Improvement of Infants Hospitalized for Respiratory Syncytial Virus-Related Critical Illness.

Background: Pediatric respiratory syncytial virus (RSV)-related acute lower respiratory tract infection (LRTI) commonly requires hospitalization. The Clinical Progression Scale Pediatrics (CPS-Ped) measures level of respiratory support and degree of hypoxia across a range of disease severity, but it has not been applied in infants hospitalized with severe RSV-LRTI.

Methods: We analyzed data from a prospective surveillance registry of infants hospitalized for RSV-related complications across 39 U.

Efficacy of Intraoperative Cell Salvage on Perioperative Blood Transfusion in Pelvic and Acetabular Surgery: A Matched Cohort Analysis.

Background: Pelvic fractures often result in traumatic and intraoperative blood loss. Cell salvage (CS) is a tool where autologous blood lost during surgery is collected and recycled with anticoagulation, centrifugation to separate red blood cells, and washing to be reinfused back to the patient. The purpose of this study was to investigate our experience with CS in pelvic and acetabular surgery and its relationship to perioperative transfusion requirements.

Spatiotemporal gait parameters influencing functional mobility of people with lower limb amputation.

Background: Walking speed is a measure of functional mobility that is relatively easy to quantify. In people with lower limb amputation, reduced walking speed has been linked with specific atypical spatiotemporal gait parameters. However, the influence of atypical spatiotemporal gait parameters on the walking speed of people with unilateral transtibial amputation (TTA) and transfemoral amputation (TFA) remains unclear.

A Neighborhood-Level Hispanic Paradox: the Interaction between Hispanic Density, Neighborhood Disadvantage, and Survival in Breast Cancer Patients.

Background: To evaluate the impact of Hispanic ethnic enclaves (EE) on the relationship between neighborhood disadvantage and overall survival (OS) in breast cancer (BCa) patients.

Methods: Data from BCa patients with stage I-IV disease diagnosed between 2005-2017 was used to analyze the effects of Area Deprivation Index (ADI) scores, a measure of neighborhood disadvantage, and census-tract level Hispanic density, a measure of EE, on OS using mixed-effects Cox regression models. The final model included the following individual-level factors (age, income, race, Hispanic/Latino origin, nativity, insurance status, and comorbidities (hypertension, diabetes, and body mass index) and clinical factors (National Comprehensive Cancer Network guideline-concordant treatment, stage, and receptor subtype).

Rural Roads to cognitive Resilience (RRR): A prospective cohort study protocol.

Background: Ambient air pollution, detrimental built and social environments, social isolation (SI), low socioeconomic status (SES), and rural (versus urban) residence have been associated with cognitive decline and risk of Alzheimer's disease and related dementias (ADRD). Research is needed to investigate the influence of ambient air pollution and built and social environments on SI and cognitive decline among rural, disadvantaged, ethnic minority communities. To address this gap, this cohort study will recruit an ethnoracially diverse, rural Florida sample in geographic proximity to seasonal agricultural burning.
