Associations between accelerometer-derived sedentary behavior and physical activity with white matter hyperintensities in middle-aged to older adults.

Introduction: We examined the relationship between sedentary behavior (SB), moderate-to-vigorous physical activity (MVPA), and white matter hyperintensity (WMH) volumes, a common magnetic resonance imaging (MRI) marker associated with risk of neurodegenerative disease in middle-aged to older adults.

Methods: We used data from the UK Biobank ( = 14,415; 45 to 81 years) that included accelerometer-derived measures of SB and MVPA, and WMH volumes from MRI.

Results: Both MVPA and SB were associated with WMH volumes (β= -0.

Paediatric Sweet's syndrome with pulmonary involvement triggered by severe inflammatory bowel disease and emergent total abdominal colectomy with literature review.

Sweet's syndrome (SS) is a neutrophilic dermatosis characterised by the acute onset of erythematous papules or plaques and a constellation of symptoms including fever, leucocytosis, and histopathology demonstrating nodular, pustular, or diffuse infiltrate of neutrophils with marked papillary oedema. SS can be a manifestation of inflammatory bowel disease and often coincides with periods of disease flares. Only a few cases of SS associated with ulcerative colitis are reported in the literature, and no cases have involved pulmonary manifestations in the paediatric population.

Predicting 5-year dementia conversion in veterans with mild cognitive impairment.

Introduction: Identifying mild cognitive impairment (MCI) patients at risk for dementia could facilitate early interventions. Using electronic health records (EHRs), we developed a model to predict MCI to all-cause dementia (ACD) conversion at 5 years.

Methods: Cox proportional hazards model was used to identify predictors of ACD conversion from EHR data in veterans with MCI.

Acceptability of Hormonal Contraceptives as a Smoking Cessation Aid for Women of Reproductive Age: A Web-Based Cross-Sectional Survey.

Introduction: Cigarette smoking is the most common cause of preventable cancers and other premature morbidity and mortality. Modifying hormonal patterns using hormonal contraceptives (HCs) may lead to improved smoking cessation outcomes in women, though the acceptability of this is unknown. Therefore, we explored the willingness of reproductive-age women who smoke to use HC for cessation.

Early infant diagnosis of HIV infection: a mixed-method study of uptake and challenges at primary health centers in Lagos State, Nigeria.

Introduction: Nigeria has a low uptake of early infant diagnosis (EID) of HIV despite its high pediatric HIV infection rate. Efforts to increase the EID of HIV have been limited by many factors. This research assessed EID uptake and challenges service providers experienced in providing routine care for HIV-exposed infants.

In Search of the Holy Grail of Artificial Hearts: Are We There Yet?

Infertility and Risk of Cardiovascular Disease: A Prospective Cohort Study.

Background Certain symptoms associated with infertility are associated with cardiovascular disease, including menstrual cycle irregularity, early menopause, and obesity; however, few studies have investigated the association between infertility and cardiovascular disease risk. Methods and Results Participants in the NHSII (Nurses' Health Study II) who reported infertility (12 months of trying to conceive without success, including women who subsequently conceived) or who were gravid, with no infertility were followed from 1989 until 2017 for development of incident, physician-diagnosed coronary heart disease (CHD) (myocardial infarction, coronary artery bypass grafting, angioplasty, stent) and stroke. Time-varying Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% CIs and were adjusted a priori for potential confounding variables.

Therapy Development for Microvillus Inclusion Disease using Patient-derived Enteroids.

Unlabelled: Microvillus Inclusion Disease (MVID), caused by loss-of-function mutations in the motor protein Myosin Vb (MYO5B), is a severe infantile disease characterized by diarrhea, malabsorption, and acid-base instability, requiring intensive parenteral support for nutritional and fluid management. Human patient-derived enteroids represent a model for investigation of monogenic epithelial disorders but are a rare resource from MVID patients. We developed human enteroids with different loss-of function MYO5B variants and showed that they recapitulated the structural changes found in native MVID enterocytes.

Evolution and developmental expression of the sodium-iodide symporter (, ) gene family: Implications for perchlorate toxicology.

The vertebrate sodium-iodide symporter (NIS or SLC5A5) transports iodide into the thyroid follicular cells that synthesize thyroid hormone. The SLC5A protein family includes transporters of vitamins, minerals, and nutrients. Disruption of SLC5A5 function by perchlorate, a pervasive environmental contaminant, leads to human pathologies, especially hypothyroidism.

Reaching the "Hard-to-Reach" Sexual and Gender Diverse Communities for Population-Based Research in Cancer Prevention and Control: Methods for Online Survey Data Collection and Management.

Purpose: Around 5% of United States (U.S.) population identifies as Sexual and Gender Diverse (SGD), yet there is limited research around cancer prevention among these populations.

Are prevention of mother-to-child HIV transmission service providers acquainted with national guideline recommendations? A cross-sectional study of primary health care centers in Lagos, Nigeria.

Background: Implementation of interventions for the prevention of mother-to-child transmission (PMTCT) of HIV in low- and middle-income countries, faces several barriers including health systems challenges such as health providers' knowledge and use of recommended guidelines. This study assessed PMTCT providers' knowledge of national PMTCT guideline recommendations in Lagos, Nigeria.

Methods: This was a cross-sectional survey of a purposive sample of twenty-three primary health care (PHC) centers in the five districts of Lagos, Nigeria.

Homozygous Germline APC p.I1307K Variants: A Case Series.

Approximately 10% of all colorectal cancer is estimated to be due to an inherited predisposition. Identification of a germline pathogenic variant can aid in treatment, screening, and surveillance and help stratify familial cancer risks based on gene-specific cancer associations. The gene contributes to a small percentage of hereditary colon cancer, with most pathogenic variants causing familial adenomatous polyposis syndrome.

Association Between Sleep Disturbances With Neurodevelopmental Problems and Decreased Health-Related Quality of Life in Children With Fontan Circulation.

Background Children with Fontan circulation are known to be at increased risk for neurodevelopmental problems and decreased health-related quality of life (HRQOL), but many factors that may contribute to this risk are unknown. Sleep disturbances may be one previously unidentified factor that contributes to this risk. Methods and Results We analyzed data from the Pediatric Heart Network Fontan cross-sectional study to evaluate associations between a parent or child report of sleep disturbance with reported neurodevelopmental concerns and HRQOL in 558 children with Fontan circulation.
