Background: As people age, they spend more time in and around their domestic environments, within which opportunities for health-enhancing physical activity (PA) may be limited. We examined the associations of frequency of excursions from home with accelerometer-determined PA and the total and prolonged sedentary behavior (SB, sitting for ≥30 min) among community-dwelling older adults.
Methods: Overall, 434 older adults (men, 57.1 %; age, 70-79 years) wore an accelerometer (HJA-350IT, Omron Healthcare) for 7 days. Time spent in SB, light-intensity PA (LPA), moderate-to-vigorous PA (MVPA), and prolonged SB bout (≥30 min) were calculated. Frequencies of excursions from home were categorized as 0-3, 4-5, and 6-7 days/week. Associations of excursions with PA and SB were tested by analysis of covariance adjusted for sociodemographic characteristics.
Results: Frequencies were 14.3 %, 31.1 %, and 54.6 % for excursions 0-3, 4-5, and 6-7 days/week, respectively. For men, less frequent excursions from home were significantly associated with less MVPA and more total and prolonged SB times (estimated means [minutes/day]: MVPA, 32, 42, and 48; total SB, 589, 549, and 539; prolonged SB, 344, 288, and 265; respectively; p < 0.05). LPA was not statistically significant (p = 0.09). For women, less frequent excursions were significantly associated with all PA outcomes (SB: 536, 497, and 467; prolonged SB: 260, 213, and 204; LPA: 328, 363, and 379; MVPA: 36, 39, and 54, respectively).
Conclusions: Among community-dwelling Japanese older adults, more frequent excursions from home were associated with more PA, less SB, and more-favorable SB patterns, suggesting a potential strategy for preventive-health initiatives.

Article Synopsis
- Atrial secondary tricuspid regurgitation (A-STR) is a subtype of secondary tricuspid regurgitation (STR) that is often treated with transcatheter tricuspid valve edge-to-edge repair (T-TEER), showing distinct patient characteristics and treatment outcomes.
- A study involving 641 patients revealed that 31% had A-STR, which was linked to better heart function, a higher presence of atrial fibrillation, and more effective TR reduction post-procedure compared to nonatrial STR patients.
- A-STR patients experienced improved survival rates and lower symptomatic burdens after treatment; only 38% remained symptomatic (NYHA class ≥III) after 2 years, compared to 46

Background: Contact force (CF) changes after onset of radiofrequency (RF) delivery are not well understood and often ascribed to catheter instability.
Objectives: This study sought to characterize CF changes during RF-based pulmonary vein (PV) isolation.
Methods: Catheter-tip parameters including CF for all RF sessions were extracted from a novel catheter-mapping system from 6 patients undergoing PV isolation.
Predictors of weaning failure in ventilated intensive care patients: a systematic evidence map.

Article Synopsis
- Ventilator weaning is critical for intensive care patients to prevent complications, but not all patients can be weaned successfully, leading to extubation failure.
- The study aimed to compile an overview of empirically researched predictors for weaning failure by systematically reviewing literature and analyzing data from 140 studies.
- Results identified 145 predictors that fell into four main categories, with key predictors like the rapid shallow breathing index and diaphragm function being most frequently studied.

Article Synopsis
- * The study used data from the middle Eocene Shahejie Formation in eastern China, revealing that high primary productivity and anoxic bottom waters led to significant organic carbon preservation.
- * Transient geological events like volcanic eruptions and hydrothermal fluid input affected the geochemistry of the lake's waters, but bacterial sulfate reduction played a crucial role in maintaining conditions that favored organic carbon accumulation.
Clinical Consequences of Delayed Gastric Emptying With GLP-1 Receptor Agonists and Tirzepatide.

Article Synopsis
- Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) are commonly used to manage type 2 diabetes and obesity, helping to slow gastric emptying which can help control blood sugar levels but may lead to issues like retained gastric contents during medical procedures.
- A review of studies indicates that while retained gastric contents during endoscopy is more common with GLP-1 RA usage, serious complications like pulmonary aspiration are rare, but guidelines for managing these medications during procedures are limited and not well-defined.
- To enhance patient safety, further research is needed on strategies such as extended fasting before procedures, ultrasound checks for gastric contents, and the potential use of prokinetic drugs like erythromycin.
