Chronic obstructive pulmonary disease (COPD) is common in people living with HIV (PLWH). We sought to evaluate the appropriateness of COPD diagnosis and management in PLWH, comparing results to HIV-uninfected persons. We conducted a cross-sectional analysis of Veterans enrolled in the Examinations of HIV-Associated Lung Emphysema study, in which all participants underwent spirometry at enrollment and reported respiratory symptoms on self-completed surveys. ⋯ COPD was frequently misdiagnosed and under-diagnosed in PLWH, similar to uninfected-veterans. Among PLWH with COPD and a likely indication for therapy, long-acting inhalers were prescribed infrequently, particularly guideline-concordant, first-line long-acting bronchodilators. Although not a first-line controller therapy for COPD, inhaled corticosteroids were prescribed more often.

For patients with ischemic stroke, intravenous (IV) thrombolysis with Urokinase within 6 hours has been accepted as beneficial, but its application is limited by high risk of hemorrhagic complications after thrombolysis. This study aimed to analyze the risk factors of hemorrhagic complications after intravenous thrombolysis using Urokinase in acute cerebral infarction (ACI) patients. Total 391 consecutive ACI patients were enrolled and divided into 2 groups: the hemorrhagic complications group and the non-hemorrhagic complications group. ⋯ Univariate analysis showed significant differences in prothrombin time, atrial fibrillation (AF), Mean platelet volume, large platelet ratio (L-PLR), triglyceride (TG), Lactate dehydrogenase, alanine aminotransferase (ALT), high-density lipoprotein, and baseline National Institute of Health Stroke Scale score between the hemorrhagic complications and the non-hemorrhagic complications group (P < .1). Multivariate logistic regression analysis indicated that AF (odds ratio [OR] = 2.91, 95% confidence interval [CI] = 1.06-7.99 P = .039) was the risk factor of hemorrhagic complications, while ALT (OR = 0.27, 95% CI = 0.10-0.72 P = .009) and TG (OR = 0.16, 95% CI = 0.06-0.45 P = .000) were protective factors of hemorrhagic complications. For patients with AF and lower levels of ALT or TG, the risk of hemorrhagic complications might increase after ACI.

Recent studies have shown that QT interval prolongation is associated with disease severity and predicts mortality in systemic inflammatory diseases, particularly rheumatoid arthritis. Systemic pro-inflammatory cytokines released from synovial tissues in rheumatoid arthritis, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α, could have direct effects on cardiac electrophysiology, particularly changes in the expression and function of potassium and calcium channels, resulting in QT interval prolongation on surface electrocardiogram (ECG) and an increased predisposition to develop lethal ventricular arrhythmias. However, reports on torsade de pointes (TdP) due to acquired long QT syndrome in patients with polymyalgia rheumatica (PMR) are limited. ⋯ IL-6 hyperproduction in inflamed tissues has been widely confirmed in PMR. Frequent PACs with various patterns of aberrant conduction, QT interval prolongation, and morphological T-U wave variability followed by TdP, for which IL-6-mediated enhancement of L-type Ca2+ current and inhibition of the rapid component of the delayed rectifier K+ current are the most likely mechanisms, were documented in an elderly Japanese woman with PMR. ECG may be recorded once in patients with active PMR even when these patients do not complain of palpitation or syncope. If QT interval prolongation or arrhythmia, including even PACs, is observed, follow-up ECG may be warranted, particularly for patients with some risk factors for QT prolongation that could lead to TdP, such as advanced age, female sex, hypopotassemia, and polypharmacy.

International evidence-based guidelines recommend self-management support for stroke survivors to improve their health outcomes. We developed a 4-week nurse-led stroke self-management programme (SSMP) and conducted a randomised controlled trial to assess its effects. This paper reports the findings of a qualitative study nested within the randomised controlled trial to explore stroke survivors' experiences of SSMP participation. ⋯ Suggestions were made to enhance their participation experiences, including increased home visits and group sessions, making group session attendance optional and arranging them more accessibly, meeting the survivors who shared their survival experiences in the videos, and access to the videos online. This study concurred that the SSMP enhanced stroke survivors' self-efficacy in self-management. Rearrangement of the programme format and enhancements in accessibility could be further examined to enable more effective stroke self-management.

Patients with ST-elevation myocardial infarction (STEMI) show an inflammatory response. The level of systemic inflammation is known to affect platelet aggregation function and antiplatelet therapy, which leads to different clinical prognosis. This study aims to evaluate the prognostic implication of systemic inflammatory state in patients with STEMI undergoing percutaneous coronary intervention. ⋯ Platelet inhibition function of clopidogrel decreases progressively at different inflammation levels. The different levels of hs-CRP were demonstrated to be associated with MACEs at follow-up assessments. The presence of hs-CRP was not only significantly associated with platelet inhibition function, but was also a prognostic marker in STEMI.
