Intracytoplasmic sperm injection (ICSI) is a cornerstone in managing male infertility, especially in obstructive azoospermia (OA) and non-obstructive azoospermia (NOA), necessitating sperm retrieval via testicular sperm extraction (TESE) or microdissection TESE (mTESE). However, the varied post-sperm extraction processing methods pose uncertainty regarding optimal approaches. To address this, a systematic review following preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P) guidelines was conducted, identifying 16 relevant studies.

Adult neurogenesis continuously produces new neurons critical for cognitive plasticity in adult rodents. While it is known transforming growth factor-β signaling is important in embryonic neurogenesis, its role in postnatal neurogenesis remains unclear. In this study, to define the precise role of transforming growth factor-β signaling in postnatal neurogenesis at distinct stages of the neurogenic cascade both in vitro and in vivo, we developed two novel inducible and cell type-specific mouse models to specifically silence transforming growth factor-β signaling in neural stem cells in (mGFAPcre-ALK5fl/fl-Ai9) or immature neuroblasts in (DCXcreERT2-ALK5fl/fl-Ai9).

Toward a biological definition of neuronal and glial synucleinopathies.

Nat Med

January 2025

Department of Neurology & Neurological Sciences, Stanford Movement Disorders Center, Stanford University, Stanford, CA, USA.

Cerebral accumulation of alpha-synuclein (αSyn) aggregates is the hallmark event in a group of neurodegenerative diseases-collectively called synucleinopathies-which include Parkinson's disease, dementia with Lewy bodies and multiple system atrophy. Currently, these are diagnosed by their clinical symptoms and definitively confirmed postmortem by the presence of αSyn deposits in the brain. Here, we summarize the drawbacks of the current clinical definition of synucleinopathies and outline the rationale for moving toward an earlier, biology-anchored definition of these disorders, with or without the presence of clinical symptoms.

Oxyntic gland adenomas (OGAs) are benign gastric neoplasms composed of gland-forming epithelial cells with predominantly chief cell differentiation resembling oxyntic glands confined to the mucosa. If the tumor has submucosal invasion, it should be classified as gastric adenocarcinoma of fundic gland type. The OGAs can pose a diagnostic challenge, as they can resemble aggressive gastric neoplasms.

Background: Understanding similarities and differences between hesitancy for influenza and COVID-19 vaccines could facilitate strategies to improve public receptivity toward vaccination.

Methods: We compared hesitancy for COVID-19 vaccines during the first 13 months of availability (January 2021-January 2022) with hesitancy for influenza vaccines in the 15 months prior to COVID-19 vaccine availability (October 2019-December 2020) among adults hospitalized with acute respiratory illness at 21 hospitals in the United States. We interviewed patients regarding vaccination status, willingness to be vaccinated, and perceptions of vaccine safety and efficacy.

Background: Collaborative research consortia provide an efficient method to increase sample size, enabling evaluation of subgroup heterogeneity and rare outcomes. In addition to missing data challenges faced by all cohort studies like nonresponse and attrition, collaborative studies have missing data due to differences in study design and measurement of the contributing studies.

Methods: We extend ROSETTA, a latent variable method that creates common measures across datasets collecting the same latent constructs with only partial overlap in measures, to define a common measure of socioeconomic status (SES) across cohorts with varying indicators in the Environmental influences on Child Health Outcomes Cohort, a consortium of pregnancy and pediatric cohorts.

Managing conflicts of interest (COIs) in scientific decision-making is important for minimizing bias and fostering public trust in science. Proper management of COIs has added significance when scientists are making decisions that impact public policy, such as assessing substances for carcinogenicity. The International Agency for Research on Cancer (IARC) organizes expert working groups to identify putative carcinogens and determine whether or not the hazard is likely to present significant potential harm to humans.

Bone Health and Linear Growth in Children with Familial Hypoparathyroidism Treated with Human Parathyroid Hormone 1-34.

J Clin Endocrinol Metab

January 2025

Gastroenterology, Hepatology and Nutrition, Cincinnati Childrens Hospital Medical Center, Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, OH.

Context: Our study explores the impact of human PTH 1-34 injections (PTH therapy) on growth, areal bone mineral density (BMD), and bone quality (measured by trabecular bone score, TBS) in hypoparathyroidism due to autoimmune polyendocrine syndrome type 1 (APS-1) or an activating variant of the calcium sensing receptor (CaR).

Objective: To assess associations of 1) age and PTH therapy duration with age-standardized Z-scores for height (HAZ), BMD (BMD-Z), and TBS (TBS-Z) in CaR or APS-1, and 2) APS-1 disease severity with BMD-Z and TBS-Z.

Methods: This secondary analysis pooled linear growth and lumbar spine (LS) DXA data from studies of hypoparathyroidism with mean baseline age of 13.

Background: Infective endocarditis is characterized by the colonization of heart valves by virulent microorganisms. It commonly manifests as involvement of a single heart valve -single-valve infective endocarditis (SIE), while in some patients, two or more heart valves are concomitantly infected -multivalvular infective endocarditis (MIE). The risk of complications and prognosis of MIE as opposed to SIE are unknown.

Gsx2 is a homeodomain transcription factor critical for development of the ventral telencephalon and hindbrain of the mouse. Loss of Gsx2 function results in severe basal ganglia dysgenesis as well as defects in the nucleus tractus solitarius (nTS) of the hindbrain together with respiratory failure at birth.

Background: Objective indices of functional capacity in patients with diabetic cardiomyopathy and stage B heart failure (HF) have not been comprehensively defined. We sought to characterize the cardiopulmonary exercise characteristics of individuals with diabetic cardiomyopathy at high risk for overt HF.

Methods: The relationships from cardiopulmonary exercise testing with clinical and laboratory characteristics of participants with diabetic cardiomyopathy were evaluated using baseline data from the ARISE-HF trial (Aldose Reductase Inhibition for Stabilization of Exercise Capacity in Heart Failure).

Thyroid cancer, one of the most common endocrine tumors, generally has a favorable prognosis but remains a significant medical and societal concern due to its high incidence. Early diagnosis and treatment of differentiated thyroid cancer (DTC) significantly affect long-term outcomes, requiring the selection and application of appropriate initial treatments to improve prognosis and quality of life. Recent advances in technology and health information systems have enhanced our understanding of the molecular genetics of thyroid cancer, facilitating the identification of aggressive subgroups and enabling the accumulation of research on risk factors through big data.
