Background: The prognostic value of the short-term blood pressure variability (BPV) from the 24-hour ambulatory blood pressure monitoring (ABPM) remains controversial. The present study aimed to investigate the long-term prognostic value of a high BPV in normotensive and hypertensive subjects from a community-based population.
Methods: A cohort of 624 normotensive and 633 untreated hypertensive Taiwanese participants (overall 669 men, aged 30-79 years) with baseline ABPM and 20-year all-cause and cardiovascular mortality data was drawn from a community-based survey. BPV was assessed by the read-to-read average real variability of the 24-hour diastolic and systolic blood pressure (SBP) (ARVd and ARVs, respectively).
Results: In Cox proportional hazards analysis, ARVd predicted cardiovascular mortality independently of office SBP (hazard ratios (HRs) and 95% confidence intervals (CIs) per 1 SD: 1.31 (1.10-1.55), respectively, bivariate analysis), 24-hour SBP (HR: 1.19, 95% CI: 1.00-1.43), and conventional risk factors (age, sex, smoking, total cholesterol, high-density lipoprotein cholesterol, and fasting blood glucose, HR: 1.40, 95% CI: 1.18-1.67). In subjects with hypertension, a high vs. low ARVd (median: 8.8mm Hg) significantly predicted cardiovascular mortality (HR: 2.11, 95% CI: 1.23-3.62 and HR: 2.04, 95% CI: 1.19-3.51, respectively), when the conventional risk factors plus office SBP or 24-hour SBP were accounted for, respectively. Similar but less significant results were obtained with ARVs. A high ARVd or ARVs did not significantly predict cardiovascular mortality in the normotensive subjects.
Conclusions: A high short-term BPV is significantly predictive of long-term cardiovascular mortality in untreated hypertensive but not normotensive community-based subjects, independently of office or 24-hour SBP.

Introduction: Blunt traumatic aortic injury (TAI) is a critical condition and a leading cause of mortality in trauma patients, often resulting from high-speed accidents. Thoracic endovascular aortic repair (TEVAR) has developed into the preferred therapeutic approach due to its minimally invasive nature and promising outcomes. This study evaluates the safety and efficacy of TEVAR for managing TAI over a 10-year period at a Level-1 trauma center.

Sepsis-induced acute lung injury (ALI) is a common acute and severe reason of death in the intensive care unit. Although the pathogenesis is complicated and multifactorial, elevated inflammation and oxidative stress are considered as fundamental mechanisms for the progression of ALI. Anemonin is a natural compound with diverse biological properties including anti-inflammatory and anti-oxidative effects.

Background: Most older patients with atrial fibrillation (AF) have comorbidities. However, it is unclear whether specific comorbidity patterns are associated with adverse outcomes. We identified comorbidity patterns and their association with mortality in multimorbid older AF patients with different multidimensional frailty.

Heart failure is a complex clinical syndrome and pediatric heart failure (PHF) has a high mortality rate. Early diagnosis is crucial for treatment and management of PHF. In clinical practice, various tests and examinations play a key role in the diagnosis of PHF, including continuously updated biomarkers, echocardiography, and cardiac magnetic resonance imaging.

Background: Despite the physiological advantages of positive end-expiratory pressure (PEEP), its optimal utilization during one-lung ventilation (OLV) remains uncertain. We aimed to investigate whether individualized PEEP titration by lung compliance is associated with a reduced risk of postoperative pulmonary complications during OLV.
Methods: We searched PubMed, Embase, and the Cochrane Central Register of Controlled Trials until April 1, 2024, to identify published randomized controlled trials that compared individualized PEEP titration by lung compliance with fixed PEEP during OLV.
