Gut microbes with the genes determine TMAO production from L-carnitine intake and serve as a biomarker for precision nutrition.

Gut microbial metabolism of L-carnitine, which leads to the production of detrimental trimethylamine N-oxide (TMAO), offers a plausible link between red meat consumption and cardiovascular risks. Several microbial genes, including , the operon, and the recently identified gene cluster, have been implicated in the conversion of dietary L-carnitine into TMA(O). However, the key microbial genes and associated gut microbes involved in this pathway have not been fully explored.

Sacituzumab Govitecan in Patients With Relapsed/Refractory Advanced Head and Neck Squamous Cell Carcinoma: Results From the Phase 2 TROPiCS-03 Basket Study.

Purpose: Treatment options for advanced head and neck squamous cell carcinoma (HNSCC) previously treated with platinum-based chemotherapy and a programmed death-1 (PD-1) inhibitor are limited. Trophoblast cell-surface antigen 2 (Trop-2) is highly expressed in HNSCC. Sacituzumab govitecan (SG) is a Trop-2-directed antibody-drug conjugate approved for patients with certain previously treated solid tumors.

Alternative splicing of transcript mediates the response of circadian clocks to temperature changes.

Circadian clocks respond to temperature changes over the calendar year, allowing organisms to adjust their daily biological rhythms to optimize health and fitness. In , seasonal adaptations are regulated by temperature-sensitive alternative splicing (AS) of () and () genes that encode key transcriptional repressors of clock gene expression. Although () gene encodes the critical activator of circadian gene expression, AS of its transcripts and its potential role in temperature regulation of clock function have not been explored.

Taste triggers a homeostatic temperature control in hungry flies.

Hungry animals consistently show a desire to obtain food. Even a brief sensory detection of food can trigger bursts of physiological and behavioral changes. However, the underlying mechanisms by which the sensation of food triggers the acute behavioral response remain elusive.

Evaluating How Beliefs Among Pediatric Cardiology Providers May Affect Fetal Cardiac Counseling-A National Perspective.

Background: Prenatal counseling following a fetal diagnosis of critical congenital heart disease (CCHD) is challenging and requires delivery of detailed and complete information to ensure appropriate decision making and pregnancy support.

Methods: An anonymous 50-item survey was distributed to providers who performed fetal cardiac counseling. The primary purpose was to evaluate on a national scale physician beliefs and attitudes toward available choices after a fetal diagnosis of CCHD and their association with reported counseling practices.

Implications of comprehensive geriatric assessment and Traditional Chinese Medicine constitution types for integrative geriatric care.

Background: Complementary medicine may enhance conventional geriatric care, but clinical guidance for incorporating Traditional Chinese Medicine (TCM) therapies remains limited. This study aimed to investigate the link between TCM body constitutions and comprehensive geriatric assessment scores in older adults.

Method: This prospective observational study recruited 100 participants aged 65 and older between January 2020 and December 2021.

Loneliness as a Predictor of Disability in Older Adults: Implications of the UCLA Loneliness Scale Cutoff Score Across Cultural Contexts.

Background: This letter responds to the study by Tomida et al. (2024) that validates the optimal cutoff score for the UCLA Loneliness Scale (UCLA-LS) to predict disability among older Japanese adults. The study identifies a cutoff score of 44, providing a significant indicator for the early detection of at-risk individuals.

Carvedilol Activates a Myofilament Signaling Circuitry to Restore Cardiac Contractility in Heart Failure.

Phosphorylation of myofilament proteins critically regulates beat-to-beat cardiac contraction and is typically altered in heart failure (HF). β-Adrenergic activation induces phosphorylation in numerous substrates at the myofilament. Nevertheless, how cardiac β-adrenoceptors (βARs) signal to the myofilament in healthy and diseased hearts remains poorly understood.

The impact of specialty training and physician attitudes on fetal cardiac counseling.

Objective: Fetal cardiac anomalies are the most commonly diagnosed structural anomalies. In these cases, Maternal-Fetal Medicine (MFM) specialists are tasked with counseling patients on a spectrum of diagnoses as well as their prognostic implications. A recent study of pediatric cardiologists demonstrated that personal beliefs regarding termination impact the counseling provided to patients.

Are outcomes of locally advanced cervical cancer associated with prebrachytherapy hemoglobin values and transfusion practice? An observational study comparing two large academic centres with divergent clinical guidelines.

Background And Purpose: Anemia is common in locally advanced cervical cancer. Clinical practice varies greatly for management of anemia during brachytherapy, with some centres providing red cell transfusion to increase hemoglobin levels above 100 g/L.

Materials And Methods: This is a retrospective observational cohort study of adult patients with cervical cancer treated with brachytherapy at two academic hospitals.

Transcriptome analysis of Drosophila suzukii reveals molecular mechanisms conferring pyrethroid and spinosad resistance.

Drosophila suzukii lay eggs in soft-skinned, ripening fruits, making this insect a serious threat to berry production. Since its 2008 introduction into North America, growers have used insecticides, such as pyrethroids and spinosads, as the primary approach for D. suzukii management, resulting in development of insecticide resistance in this pest.

SGLT2 inhibition improves PI3Kα inhibitor-induced hyperglycemia: findings from preclinical animal models and from patients in the BYLieve and SOLAR-1 trials.

Purpose: Alpelisib plus fulvestrant demonstrated a significant progression-free survival benefit versus fulvestrant in patients with PIK3CA-mutated HR+ /HER2- advanced breast cancer (ABC) (SOLAR-1). Hyperglycemia, an on-target adverse effect of PI3Kα inhibition, can lead to dose modifications, potentially impacting alpelisib efficacy. We report data from preclinical models and two clinical trials (SOLAR-1 and BYLieve) on Sodium glucose cotransporter 2 inhibitor (SGLT2i) use to improve PI3Kα inhibitor-associated hyperglycemia.

The results of preventing postoperative achilles tendon adhesion using cross-linked and non-cross-linked hyaluronic acid, a study with rat model.

Background: There are many adhesion barrier materials, cross-linked or non-cross-linked hyaluronic acid (HA), used during surgeries.

Purpose: This study investigates the efficacy of cross-linked and non-cross-linked HA in preventing Achilles tendon adhesions. We hypothesized that non-cross-linked HA may be more effective than cross-linked HA in preventing Achilles tendon adhesions following injury and repair.

SAGES guidelines for the surgical treatment of hiatal hernias.

Background: Hiatal hernia (HH) is a common condition. A multidisciplinary expert panel was convened to develop evidence-based recommendations to support clinicians, patients, and others in decisions regarding the treatment of HH.

Methods: Systematic reviews were conducted for four key questions regarding the treatment of HH in adults: surgical treatment of asymptomatic HH versus surveillance; use of mesh versus no mesh; performing a fundoplication versus no fundoplication; and Roux-en-Y gastric bypass (RYGB) versus redo fundoplication for recurrent HH.
