Objectives:
The coronavirus disease 2019 pandemic led to various intensities of lockdowns, affecting lifestyles globally. This study investigates the impact of partial lockdown versus total lockdown on adult physical activity (PA) and sedentary behavior.
Methods:
A cross-sectional online survey was conducted from April 2020 to October 2020, with 493 participants included in the analysis.
Results:
The analysis revealed no significant differences in total PA or total sitting time between partial lockdown and total lockdown scenarios. However, moderate physical activity (MPA) significantly decreased during total lockdowns, with more pronounced reductions among females than males. Notably, a positive correlation was found between household area and MPA, suggesting that larger living spaces may encourage more PA. A negative correlation was observed between sitting time and MPA during both types of lockdown.
Conclusions
Total lockdown conditions were associated with a significant decrease in MPA, highlighting sex disparities in PA responses. Living space size emerged as a crucial factor in maintaining PA levels during restricted conditions. This study emphasizes the need to consider environmental and demographic factors in public health strategies during prolonged periods of restricted movement.

BACKGROUND:
Antithrombotic strategies after percutaneous coronary interventions (PCI) in elderly patients on oral anticoagulant therapy (OAT) are debated due to the balance between ischemic and bleeding risks. Recent guidelines recommend early transitioning from triple antithrombotic therapy to dual antithrombotic therapy, but there are limited data on elderly patients.
METHODS:
We performed a post-hoc age-specific analysis of the PERSEO Registry population aimed to compare clinical features, therapeutic strategies, and outcomes of individuals aged ≥ 80 years and < 80 years who were on OAT and underwent PCI with stent. The primary endpoint was net adverse clinical events at 1-year follow-up. Secondary endpoints included major adverse cardiac and cerebral events (MACCE), major bleeding [Bleeding Academic Research Consortium (BARC) type 3-5], and clinically relevant bleeding (BARC type 2-5).
RESULTS:
Among the 1234 patients enrolled, 31% of patients were aged ≥ 80 years (84 ± 3 years, 76% males). Compared to younger patients, elderly patients had higher rates of comorbidities such as hypertension, anaemia or chronic kidney disease, and atrial fibrillation was the leading indication for OAT. Elderly patients were more often discharged on dual antithrombotic therapy (23%) compared to younger patients (13%) (P < 0.0001). They experienced higher net adverse clinical events (38% vs. 21%, P < 0.001), MACCE (24% vs. 12%, P < 0.001), as well as higher bleeding rates. Specifically, rates of major bleeding (9% vs. 6%, P = 0.026), and clinically relevant bleeding (21% vs. 12%, P < 0.001) were significantly higher in elderly patients.
CONCLUSIONS
Elderly patients on OAT undergoing PCI are a particular frail population with higher risk of MACCE and bleeding compared to younger patients despite a less aggressive antithrombotic therapy.

ObjectiveDetection and quantification of RNA synthesis in cells is a widely used technique for monitoring cell viability, health, and metabolic rate.After exposure to environmental stimuli, both the internal reference gene and target gene would be degraded. As a result, it is imperative to consider the accurate capture of nascent RNA and the detection of transcriptional levels of RNA following environmental stimulation. This study aims to create a Click Chemistry method that utilizes its property to capture nascent RNA from total RNA that was stimulated by the environment. MethodsThe new RNA was labeled with 5-ethyluridine (5-EU) instead of uracil, and the azido-biotin medium ligand was connected to the magnetic sphere using a combination of “Click Chemistry” and magnetic bead screening. Then the new RNA was captured and the transcription rate of 16S rRNA was detected by fluorescence molecular beacon (M.B.) and quantitative reverse transcription PCR (qRT-PCR). ResultsThe bacterial nascent RNA captured by “Click Chemistry” screening can be used as a reverse transcription template to form cDNA. Combined with the fluorescent molecular beacon M.B.1, the synthesis rate of rRNA at 37℃ is 1.2 times higher than that at 15℃. The 16S rRNA gene and cspI gene can be detected by fluorescent quantitative PCR,it was found that the measured relative gene expression changes were significantly enhanced at 25℃ and 16℃ when analyzed with nascent RNA rather than total RNA, enabling accurate detection of RNA transcription rates. ConclusionCompared to other article reported experimental methods that utilize screening magnetic columns, the technical scheme employed in this study is more suitable for bacteria, and the operation steps are simple and easy to implement, making it an effective RNA capture method for researchers.

Objectives:
Existing standards of care recommend operative management for fragility fractures of the hip. Early
intervention has been associated with lower incidence of morbidity and mortality. A lack of consensus remains in the Philippines however, regarding timing of surgery. We sought to determine the effects of surgical timing on in-hospital complications among Filipino patients with fragility hip fractures.
Methods:
All patients admitted for fragility hip fractures in a single tertiary-care facility from 2014-2016 were
analyzed retrospectively. Subjects treated within 72 hours were grouped under “early intervention,” while those managed beyond were designated “delayed intervention.” Primary outcomes were complications during admission, while secondary outcome was length of hospital stay. A total of 96 patients met our inclusion criteria, of which 41 (42.71%) underwent early intervention. Baseline characteristics for both groups were comparable.
Results:
A significantly lower incidence of pressure ulcers (2.4% for ≤72hours vs 45.5%; p=<0.0001), pneumonia
(7.32% vs 47.27%; p=<0.0001), and urinary tract infection (4.88% vs 40%; p=<0.0001), as well as shorter hospital stay (mean: 8.85 days±5.4 vs 14.6 days±13.3; p=0.01) were seen in the early intervention group. More cases of documented deep vein thrombosis were recorded in the delayed intervention group (83.3% versus 16.6%), as was the only case of in-hospital mortality.
Conclusion
Early intervention showed a significantly lower incidence of in-hospital complications among patients with fragility fractures of the hip, suggesting that surgery within 72 hours may lead to better outcomes by helping to reduce the incidence of pressure sores, pneumonia, and urinary tract infection among Filipinos with hip fractures, while reducing length of admission.

Objective:
To evaluate the accuracy of the Classification and Regression Tree (CART) model in
prognosticating visual outcomes of patients with open-globe injuries
Methods:
This was a retrospective, single-center, cohort study of patients with open-globe injuries seen over
a two-year period. Purposive sampling of hospital medical records was done to collect data from both in- and
out-patient cases. The CART algorithm was utilized to determine the predicted visual outcome for each case,
and the accuracy of prognostication was measured by computing for sensitivity, specificity, positive predictive
value, and negative predictive value. The area under the receiver operating characteristic curve was used to
check its discriminatory capability.
Results:
A total of 65 eyes (65 patients) with the following diagnoses based on the Birmingham Eye Trauma
Terminology (BETT) classification were included: penetrating eye injury (n=58), globe rupture (n=2), and intraocular foreign body (n=5). Majority were male patients (81.5%) in the 17-39 year age group (40%). The
sensitivity and specificity of CART were 100% (95% CI 93.6 to 100%) and 77.8% (95% CI 40 to 97.2%),
respectively, with an overall accuracy of 96.9% (95% CI 89.3 to 99.6%). Area under the curve (AUC) was
statistically significant at 0.89 (95% CI 0.79 to 0.95), indicating that the CART model can discriminate vision
survival versus no vision.
Conclusion
The CART model demonstrated high accuracy in prognosticating visual outcomes after an openglobe injury in the local setting. It may be used as a helpful tool to guide treatment decisions in open-globe injuries.
