Eight-week high-intensity inspiratory muscle training improves cardiac autonomic function in COPD: a randomized controlled trial

A randomized trial in 39 stable COPD patients found that eight weeks of 30 inspiratory breaths twice daily at the highest tolerable intensity shifted heart-rate variability toward greater parasympathetic activity and improved six-minute walk distance and health scores versus control. The trial was small, lacked sham training, and did not measure long-term cardiac events or exacerbations.

Prevalence and prognostic impact of unrecognized myocardial infarction detected by cardiac magnetic resonance in Thai patients with obesity

Among 1,053 Thai patients with BMI at least 25 kg/m2 who underwent cardiac magnetic resonance, 9.9% had scars consistent with previously unrecognized myocardial infarction. This group had more major cardiovascular events over a median 9.2 years, but most participants were selected for CMR because coronary disease was suspected, so this is not population prevalence among people with obesity.

Aggregatibacter actinomycetemcomitans NadN Contributes to Neutrophil Extracellular Trap Degradation

Cell-based experiments found that Aggregatibacter actinomycetemcomitans, a bacterium associated with periodontitis, can degrade neutrophil extracellular traps after capture and identified membrane-associated NadN as an important mediator. Expressing NadN in Lactococcus lactis conferred NET-degrading activity, but patient or animal evidence of disease impact is not yet available.

Measurement of Plasma Free Hemoglobin Using the Hemolysis Index of the Mindray BS-800

A Siriraj team validated the Mindray BS-800 hemolysis index for plasma free hemoglobin against the Harboe method, reporting high precision and correlation across the evaluated range and a 2 mg/dL detection limit. High bilirubin caused up to 15% negative bias, and analytical validation does not establish clinical-outcome benefit.

Phylogenomic structure and resistance profiles of clinical Proteus mirabilis from a Thai hospital

Whole-genome analysis of 17 clinical Proteus mirabilis isolates from hospitals in Narathiwat found genetic diversity and multiple resistance genes despite broad phenotypic susceptibility. qnrD1 appeared on similar Col3M-associated contigs in two isolates, suggesting possible mobile elements, but the small study did not demonstrate transmission.

Severe Pregnancy-Associated Acute Kidney Injury and Maternal Vulnerability

Electronic records covering 4,094,111 US pregnancies showed severe pregnancy-associated acute kidney injury rising from 9.0 to 27.6 per 10,000 pregnancies between 2012-2013 and the COVID-19 era. Pre-existing cardiometabolic vulnerability was associated with risk, but observational data cannot separate infection, access, testing, and secular trends.

Integrative hematological and transcriptomic analysis reveals monocyte alterations and molecular signatures of inflammatory-coagulation crosstalk in long COVID

A comparison of 21 people with long COVID and 24 asymptomatic controls found lower white-cell, monocyte, and platelet counts and longer APTT. Integrated with a separate public transcriptomic dataset, the findings support a proposed inflammation-coagulation model, but the small and non-identical datasets cannot establish mechanism.

Toxicological Assessment of Oligofructans Derived from Raw Sugar Fermentation by Bacillus subtilis TISTR 001 and Their Modulatory Effects on Rat Gut Microbiota

Thai researchers evaluated oligofructans produced from raw sugar using Bacillus subtilis TISTR 001. Rats showed no treatment-related mortality or toxicity at doses up to 2,000 mg/kg/day for 90 days, alongside reported shifts in gut microbial taxa. These are preclinical animal findings and do not establish human safety or benefit.

A Multi-Frequency SAR Framework for Methane Emission Estimation in Thai Rice Paddies

A GISTDA-led framework combines Sentinel-1 and ALOS-2 radar with IPCC accounting to detect crop timing, classify water regimes, and estimate methane from irrigated rice in Thailand's central plain. Mean absolute error was 18.5 kg CH4/ha, but structural uncertainty in the IPCC Tier 1 emission factor exceeded all algorithmic errors combined.

Predictors of Early Recurrence and Survival Outcomes Following Curative Resection for Colorectal Liver Metastases and the Role of Salvage Surgery: A Retrospective Cohort Study

In a retrospective cohort of 109 patients undergoing liver resection for colorectal liver metastases, high tumor burden, major intraoperative blood loss, T3/T4 primary disease, and RAS mutation were associated with early recurrence. Selected patients undergoing salvage re-hepatectomy had favorable long-term survival, but small subgroups and strong selection bias prevent causal conclusions.

The Study of Efficacy and Safety of a Modified Chaihu Shugan San Formula in the Treatment of Insomnia Associated with Stress: A Pilot Clinical Evaluation

A 30-participant pre-post pilot reported lower sleep-quality and stress scores after four weeks of twice-daily modified Chaihu Shugan San, without clear liver or renal safety signals. Without randomization, a control group, or placebo, the study cannot separate the formula's effect from placebo, attention, or change over time.

Benefits of three consecutive sputum inductions using nebulized racemic salbutamol versus hypertonic saline in smear-negative or sputum-scarce pulmonary tuberculosis patients: a prospective randomized, double-blind study

In a randomized double-blind trial of 345 adults with suspected smear-negative or sputum-scarce pulmonary tuberculosis, three consecutive daily inductions with nebulized racemic salbutamol produced a higher combined smear-or-culture yield and fewer adverse events than 3% hypertonic saline. The single-center study evaluates specimen collection for diagnosis, not tuberculosis treatment outcomes.
