Evaluating the prognostic impact of hypoperfusion intensity ratio in acute ischemic stroke patients undergoing early-phase endovascular thrombectomy.

This research aimed to assess the prognostic relevance of the hypoperfusion intensity ratio (HIR) concerning 90-day outcomes in patients with acute ischemic stroke (AIS) managed within the early intervention window. A retrospective review was conducted on AIS patients who received pretreatment computed tomography perfusion imaging and endovascular thrombectomy due to large vessel occlusions in the anterior circulation between January 2020 and September 2022. Clinical data, including the Alberta Stroke Program Early Computed Tomography Score (ASPECTS) from non-contrast CT, along with perfusion metrics such as ischemic core, hypoperfusion extent, core-penumbra mismatch, and HIR, were analyzed.

Mediation analysis identifies causal factors that lead to increased rates of kidney transplant failure in patients with peripheral vascular disease.

Background: This study aims to identify causal mediators of one-year kidney transplant failure in patients with peripheral vascular disease.

Methods: Standard Transplant Analysis and Research database was queried for adults who underwent kidney transplantation from 1987 to 2021. Multi-organ transplant, prior transplant, and living donor kidneys were excluded.

Injectable ionic hydrogel conductors: Advancing material design to transform cardiac pacing.

Direct pacing of the mid myocardium where re-entry originates can be used to prevent ventricular arrhythmias and circumvent the need for painful defibrillation or cardiac ablation. However, there are no pacing electrodes small enough to navigate the coronary veins that cross these culprit scar regions. To address this need, we have developed an injectable ionically conductive hydrogel electrode that can fill the epicardial coronary veins and transform them into flexible electrodes.

Impaired lipid homeostasis and elevated lipid oxidation of erythrocyte membrane in adolescent depression.

Adolescent depression is a globally concerned mental health issue, the pathophysiological mechanisms of which remain elusive. Membrane lipids play a crucial role in brain development and function, potentially serving as a crossroad for the abnormalities in neurotransmitters, neuroendocrine, inflammation, oxidative stress, and energy metabolism observed in depressed adolescents. The primary aim of this study was to investigate the erythrocyte membrane lipid profile in adolescent depression.

Modeling, synthesis and cell-based evaluation of pyridine-substituted analogs of CD3254 and fluorinated analogs of CBt-PMN as novel therapeutics.

Six pyridine analogs of (E)-3-(3-(1,2,3,4-tetrahydro-1,1,4,4,6-pentamethylnaphthalen-7-yl)-4-hydroxyphenyl)acrylic acid-or CD3254 (11)-in addition to two novel analogs of 1-(3,5,5,8,8-pentamethyl-5,6,7,8-tetrahydronaphthalen-2-yl)-1H-benzo[d][1,2,3]triazole-5-carboxylic acid (CBt-PMN or 23) were prepared and evaluated for selective retinoid-X-receptor (RXR) agonism alongside bexarotene (1), an FDA-approved drug for cutaneous T-cell lymphoma (CTCL). Treatment with 1 often elicits side-effects by disrupting or provoking other RXR-dependent nuclear receptors and cellular pathways. All analogs were assessed through modeling for their ability to bind RXR and then evaluated in human colon and kidney cells employing an RXR-RXR mammalian-2-hybrid (M2H) system and in an RXRE-controlled transcriptional assay.

Neural effects of memory training to reduce false memories in older adults: Univariate and multivariate analyses.

The growing population of older adults emphasizes the need to develop interventions that prevent or delay some of the cognitive decline that accompanies aging. In particular, as memory impairment is the foremost cognitive deficit affecting older adults, it is vital to develop interventions that improve memory function. This study addressed the problem of false memories in aging by training older adults to use details of past events during memory retrieval to distinguish targets from related lures.

Development of the Lee Symptom Scale-Skin Sclerosis for chronic GVHD-associated sclerosis.

Sclerosis is a highly morbid manifestation of chronic GVHD (cGVHD), associated with distressing symptoms and significant long-term disability. A patient-reported outcome measure (PRO) for cGVHD-associated sclerosis is essential to advance therapeutic trials. We aimed to develop a PRO for adults with cGVHD-associated sclerosis and evaluate and refine its content validity.

Estimating realized relatedness in free-ranging macaques by inferring identity-by-descent segments.

Biological relatedness is a key consideration in studies of behavior, population structure, and trait evolution. Except for parent-offspring dyads, pedigrees capture relatedness imperfectly. The number and length of identical-by-descent DNA segments (IBD) yield the most precise relatedness estimates.

The chromatin remodeler ADNP regulates neurodevelopmental disorder risk genes and neocortical neurogenesis.

Although chromatin remodelers are among the most important risk genes associated with neurodevelopmental disorders (NDDs), the roles of these complexes during brain development are in many cases unclear. Here, we focused on the recently discovered ChAHP chromatin remodeling complex. The zinc finger and homeodomain transcription factor ADNP is a core subunit of this complex, and de novo mutations lead to intellectual disability and autism spectrum disorder.

Acceptability of a dapivirine levonorgestrel vaginal ring in two Phase 1 trials (MTN-030/IPM 041 and MTN-044/IPM 053/CCN019): Implications for multipurpose prevention technology development.

End-user feedback early in product development is important for optimizing multipurpose prevention technologies for HIV and pregnancy prevention. We evaluated the acceptability of the 90-day dapivirine levonorgestrel ring (DPV-LNG ring) used for 14 days compared to a dapivirine-only ring (DVR-200mg) in MTN-030/IPM 041 (n = 23), and when used for 90 days cyclically or continuously in MTN-044/IPM 053/CCN019 (n = 25). We enrolled healthy, non-pregnant, HIV-negative women aged 18-45 in Pittsburgh, PA and Birmingham, AL (MTN-030 only).

Monounsaturated fatty acids from plant or animal sources and risk of type 2 diabetes in three large prospective cohorts of men and women.

Aims/hypothesis: Existing evidence on the relationship between intake of monounsaturated fatty acids (MUFAs) and type 2 diabetes is conflicting. Few studies have examined whether MUFAs from plant or animal sources (MUFA-Ps and MUFA-As, respectively) exhibit differential associations with type 2 diabetes. We examined associations of intakes of total MUFAs, MUFA-Ps and MUFA-As with type 2 diabetes risk.

Skeletal surveys for suspected infant abuse: patient-specific radiation dose estimation using a hybrid computational phantom.

Background: Radiographic skeletal survey plays an important role in the diagnosis of infant abuse. Some practitioners have expressed concerns about the radiation exposure from this examination.

Objective: To utilize state-of-the-art hybrid computational phantoms to more accurately estimate radiation doses of skeletal surveys performed for suspected infant abuse.

CD9/SOX2-positive cells in the intermediate lobe of the rat pituitary gland exhibit mesenchymal stem cell characteristics.

Adult tissue stem cells of the anterior pituitary gland, CD9/SOX2-positive cells, are believed to exist in the marginal cell layer (MCL) bordering the residual lumen of the Rathke's pouch. These cells migrate from the intermediate lobe side of the MCL (IL-MCL) to the anterior lobe side of the MCL and may be involved in supplying hormone-producing cells. Previous studies reported that some SOX2-positive cells of the anterior lobe differentiate into skeletal muscle cells.

Phase I Dose Volume Escalation of Rectally Administered PC-1005 to Assess Safety, Pharmacokinetics, and Antiviral Pharmacodynamics as a Multipurpose Prevention Technology (MTN-037).

Background: On demand, topical PrEP is desired by those preferring episodic, nonsystemic PrEP. PC-1005 gel (MIV-150, zinc, and carrageenan) exhibits in vitro antiviral HIV-1, human papillomavirus (HPV), and herpes simplex virus type 2 (HSV-2) activity, attractive for a multipurpose prevention technology candidate. We evaluated the safety, pharmacokinetics, and antiviral effect of rectally applied PC-1005.

Phenotypes of Pelvic Organ Prolapse.

Importance: The Pelvic Organ Prolapse Quantification (POP-Q) stages do not correlate with symptoms or characterize important prolapse subtypes.

Objectives: We hypothesize that clinically meaningful prolapse "phenotypes" utilizing POP-Q measurements can be defined. The primary aim was to define the phenotypes and their frequency.

HIF1α Plays a Crucial Role in the Development of TFE3-Rearranged Renal Cell Carcinoma by Orchestrating a Metabolic Shift Toward Fatty Acid Synthesis.

Tumor development often requires cellular adaptation to a unique, high metabolic state; however, the molecular mechanisms that drive such metabolic changes in TFE3-rearranged renal cell carcinoma (TFE3-RCC) remain poorly understood. TFE3-RCC, a rare subtype of RCC, is defined by the formation of chimeric proteins involving the transcription factor TFE3. In this study, we analyzed cell lines and genetically engineered mice, demonstrating that the expression of the chimeric protein PRCC-TFE3 induced a hypoxia-related signature by transcriptionally upregulating HIF1α and HIF2α.

Validation Status of Electronic Sphygmomanometers in China: A National Survey.

Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.

Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.

Exposure Contrasts of Women Aged 40-79 Years during the Household Air Pollution Intervention Network Randomized Controlled Trial.

Exposure to household air pollution has been linked to adverse health outcomes among women aged 40-79. Little is known about how shifting from biomass cooking to a cleaner fuel like liquefied petroleum gas (LPG) could impact exposures for this population. We report 24-h exposures to particulate matter (PM), black carbon (BC), and carbon monoxide (CO) among women aged 40 to <80 years participating in the Household Air Pollution Intervention Network trial.

Evaluation of the Soda Tax on Obesity and Diabetes in California: A Cost-Effectiveness Analysis.

Unlabelled: Consumption of sugar-sweetened beverages (SSBs) contributes to weight gain, obesity, and diabetes. Soda tax has been proposed to reduce consumption of SSBs. What remains unclear is whether the soda tax has an effect on health and health care costs.
