Application of image guided analyses to monitor fecal microbial composition and diversity in a human cohort.

The critical role of gut microbiota in human health and disease has been increasingly illustrated over the past decades, with a significant amount of research demonstrating an unmet need for self-monitor of the fecal microbial composition in an easily-accessible, rapid-time manner. In this study, we employed a tool for Smartphone Microbiome Evaluation and Analysis in Rapid-time (SMEAR) that uses images of fecal smears to predict microbial compositional characteristics in a human cohort. A subset of human fecal samples was randomly retrieved from the second wave of data collection in the Healthy Life in an Urban Setting (HELIUS) study cohort.

Implementation of opportunistic salpingectomy for ovarian cancer prevention: Analyzing clinical practice and key characteristics.

Introduction: Ovarian cancer (OC) is the most lethal gynecologic cancer, often diagnosed at an advanced stage due to nonspecific symptoms and lack of effective screening. Over 90% of all ovarian cancer cases are epithelial in origin, which is thought to originate from the fallopian tubes in approximately 70% of cases. Opportunistic salpingectomy (OS), the additional removal of fallopian tubes during abdominal surgery, has emerged as a preventive strategy.

AI for rapid identification of major butyrate-producing bacteria in rhesus macaques (Macaca mulatta).

Background: The gut microbiome plays a crucial role in health and disease, influencing digestion, metabolism, and immune function. Traditional microbiome analysis methods are often expensive, time-consuming, and require specialized expertise, limiting their practical application in clinical settings. Evolving artificial intelligence (AI) technologies present opportunities for developing alternative methods.

Evaluation of a patient decision aid for opportunistic salpingectomy and salpingectomy as sterilization method to prevent ovarian cancer.

Improving pre-operative binary grading: relevance of p53 and PR expression in grade 2 endometrioid endometrial carcinoma.

Objective: This study aimed to evaluate the association between pre-operative progesterone receptor (PR) and p53 expression and prognosis in pre-operative grade 2 endometrioid endometrial carcinoma compared with grade 1 and grade 3 carcinomas.

Methods: Three European endometrial carcinoma cohort studies were included. Patients with pre-operative grade 2 endometrioid carcinoma and known pre-operative PR and p53 status were included (n = 400), as were patients with pre-operative grade 1 (n = 602) or grade 3 (n = 148) endometrioid carcinomas.

A rapid, affordable, and reliable method for profiling microbiome biomarkers from fecal images.

Human and veterinary healthcare professionals are interested in utilizing the gut-microbiome as a target to diagnose, treat, and prevent (gastrointestinal) diseases. However, the current microbiome analysis techniques are expensive and time-consuming, and data interpretation requires the expertise of specialists. Therefore, we explored the development and application of artificial intelligence technology for rapid, affordable, and reliable microbiome profiling in rhesus macaques ().

Oncology Dose Selection in Subsequent Indications: What Can We Learn From FDA-approved Oncology Drugs?

Purpose: The modern oncology drug development landscape has shifted away from traditional cytotoxic chemotherapies. Following their initial approvals, many oncology drugs have been approved in subsequent indications either as monotherapy or in combination to benefit a broader patient population. To date, dose selection strategies for subsequent indications have not been systematically reviewed.

A Comparative Clinical Pharmacology Analysis of FDA-Approved Targeted Covalent Inhibitors vs. Reversible Inhibitors in Oncology.

Targeted covalent inhibitors (TCIs) are an emerging class of anticancer therapeutics. TCIs are designed to selectively engage their targeted proteins via covalent warheads. From the drug development standpoint, the covalent inhibition mechanism is anticipated to elicit the following theoretical benefits: (i) an extended duration of therapeutic action that is determined by the target protein turnover rate and not necessarily by drug half-life, (ii) a lower therapeutic dose owing to greater pharmacological potency, (iii) lower risk of off-target binding and associated adverse events, and (iv) reduced drug-drug interaction (DDI) liability due to high selectivity and low dose.

Pharmacokinetic-Pharmacodynamic Evidence From a Phase 3 Trial to Support Flat-Dosing of Rifampicin for Tuberculosis.

Background: The optimal dosing strategy for rifampicin in treating drug-susceptible tuberculosis (TB) is still highly debated. In the phase 3 clinical trial Study 31/ACTG 5349 (NCT02410772), all participants in the control regimen arm received 600 mg rifampicin daily as a flat dose. Here, we evaluated relationships between rifampicin exposure and efficacy and safety outcomes.

Efficacy of compliance with ventilator-associated pneumonia care bundle: A 24-month longitudinal study at Bach Mai Hospital, Vietnam.

Introduction: To decrease the risk of complications from ventilator-associated pneumonia, it is essential to implement preventative measures in all ICU patients. Since 2018, with the help of Japanese experts, we have applied a ventilator-associated pneumonia care bundle with 10 basic standards in patient care and monitoring. Therefore, we conducted a study to evaluate the results of applying 10 solutions to prevent ventilator-associated pneumonia over 24 months.

Blocking insulin-like growth factor 1 receptor signaling pathway inhibits neuromuscular junction regeneration after botulinum toxin-A treatment.

Botulinum toxin-A (BTX) administration into muscle is an established treatment for conditions with excessive muscle contraction. However, botulinum therapy has short-term effectiveness, and high-dose injection of BTX could induce neutralizing antibodies against BTX. Therefore, prolonging its effects could be beneficial in a clinical situation.

Potential for Larval Control and Environmental Friendliness of the Compounds Containing 2-Methyl-3,4-dihydroquinazolin-4-one Heterocycle.

2-Methylquinazolin-4(3)-one was prepared by the reaction of anthranilic acid, acetic anhydride, and ammonium acetate. The reaction of 2-methylquinazolin-4(3)-one with -aryl-2-chloroacetamides in acetone in the presence of potassium carbonate gave nine -aryl-2-(2-methyl-4-oxoquinazolin-3(4)-yl)acetamide compounds. The structures of these compounds were elucidated on the basis of their IR, H nuclear magnetic resonance (NMR), C NMR, and high-resolution mass spectrometry (HR-MS) spectral data.

First step in implementation of opportunistic salpingectomy for prevention of ovarian cancer: Current care and its determinants.

Introduction: Opportunistic salpingectomy (OS) refers to additional removal of the fallopian tubes during abdominal surgery performed for another medical indication, as prevention for ovarian cancer. As OS has been inconsistently implemented, its clinical practice varies worldwide. To reduce this variation, insight is required into current clinical practice and its determinants.
