BACKGROUND: The emergence of COVID-19 overwhelmed tuberculosis (TB) prevention and control, resulting in a decrease in TB detection rate and an increase in TB deaths. Furthermore, the temporary immunosuppressive effects, lung inflammation, and the corticosteroids used to treat COVID-19, may play a direct role in immunosuppression, leading to reactivation of either previous infection or latent TB or the development of new TB. Thus, the aim of this study was to review TB incidence in individuals who recovered from COVID-19...

As growing evidence implicates extra-renal mineralocorticoid receptor (MR) in cardiovascular disease (CVD), recent studies have defined both cell- and sex-specific roles. MR is expressed in vascular smooth muscle (SMC) and endothelial cells (EC). This review integrates published data from the past five years to identify novel roles for vascular MR in CVD, with a focus on understanding sex differences. Four areas are reviewed in which there is recently expanded understanding of the cell type- or sex-specific role of MR in: (1) obesity-induced microvascular endothelial dysfunction, (2) vascular inflammation in atherosclerosis, (3) pulmonary hypertension and (4) chronic-kidney disease (CKD)-related CVD...

Pulmonary arterial hypertension (PAH) is a progressive life-threatening disease, primarily affecting small pulmonary arterioles of the lung. Currently, there is no cure for PAH. It is important to discover new compounds that can be used to treat PAH. The mouse hypoxia-induced PAH model is a widely used model for PAH research. This model recapitulates human clinical manifestations of PAH Group 3 disease and is an important research tool to evaluate the effectiveness of new experimental therapies for PAH. Research using this model often requires the administration of compounds in mice...

Pulmonary artery hypertension (PAH) is a rare but lethal disease that affects the pulmonary vascular bed, resulting in hypoxia, respiratory distress, right heart failure, exercise limitation and mortality. Currently, many PAH specific medications are applied to ameliorate patients' symptoms, improve life quality and prolong their lives. The survival rate has improved with medical therapy but patients may still suffer from insufficient exercise capacity. Therefore, cardiopulmonary exercise test (CPET) can play an important role in the evaluation of PAH patients' risk status and treatment response, and, furthermore, it can guide the rehabilitation program...

INTRODUCTION: Heart failure with preserved ejection fraction (HFpEF), which is a common co-morbidity in patients with maintenance hemodialysis (MHD), results in substantial mortality and morbidity. However, there are still no effective therapeutic drugs available for HFpEF currently. Sacubitril/valsartan has been shown to significantly improve clinical outcomes and reverse myocardial remodeling among patients with heart failure with reduced ejection fraction (HFrEF). The effect of sacubitril/valsartan in MHD patients with HFpEF remains unclear...

Xiao Zhang, Zhao Huangfu
Pregnant individuals with pulmonary arterial hypertension (PAH) have significantly high risks of maternal and perinatal mortality. Profound changes in plasma volume, cardiac output and systemic vascular resistance can all increase the strain being placed on the right ventricle, leading to heart failure and cardiovascular collapse. Given the complex network of opposing physiological changes, strict contraception and reduction of hemodynamic fluctuations during pregnancy are important methods of minimizing the risk of maternal mortality and improving the outcomes following pregnancy...

BACKGROUND: With approval of anti-PD-1/PD-L1, metastatic non-small cell lung cancer (NSCLC) has entered the era of immunotherapy. Since immune-related adverse events (irAEs) occur commonly in patients receiving anti-PD-1/PD-L1, the landscape of death causes may have changed in metastatic NSCLC. We aim to compare patterns of death causes in metastatic NSCLC between the pre-immunotherapy and immunotherapy era to identify the consequent landscape transition of death causes. METHODS: In this cohort study, 298,48patients with metastatic NSCLC diagnosed between 2000 and 2018 were identified from the Surveillance, Epidemiology, and End Results Program...

Pulmonary arterial hypertension (PAH) is a progressive, devastating disease, and its main histological manifestation is an occlusive pulmonary arteriopathy. One important functional component of PAH is aberrant endothelial cell (EC) function including apoptosis-resistance, unchecked proliferation, and impaired migration. The mechanisms leading to and maintaining physiologic and aberrant EC function are not fully understood. Here, we tested the hypothesis that in PAH, ECs have increased expression of the transmembrane protein integrin-β5, which contributes to migration and survival under physiologic and pathological conditions, but also to endothelial-to-mesenchymal transition (EnMT)...

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare congenital disorder characterized by cutaneous capillary malformations, bone hypertrophy, and multiple venous or lymphatic malformations. KTWS is associated with chronic thromboembolic pulmonary hypertension (CTEPH), presumably due to thromboembolism from multiple vascular malformations. Here, we report the first case series of patients with KTWS-CTEPH who underwent balloon pulmonary angioplasty (BPA). Both patients are alive 20 years and 1 year after the initial diagnosis of CTEPH, respectively, and are stable with improved hemodynamics...

Risk assessment for pulmonary arterial hypertension (PAH) utilizing noninvasive prognostic variables could be more practical in real-world scenarios, especially at follow-up reevaluations. Patients who underwent comprehensive evaluations both at baseline and at follow-up visits were enrolled. The primary endpoint was all-cause mortality. Predictive variables identified by Cox analyses were further incorporated with the French noninvasive risk prediction approach. A total of 580 PAH patients were enrolled. During a median follow-up time of 47...

BACKGROUND: Pulmonary hypertension (PH) frequently co-exists in patients with severe aortic stenosis (AS). In this study, we sought to identify the implications of invasive pulmonary hemodynamics on major adverse cardiac events (MACE), biventricular function and NYHA functional class after transcatheter aortic valve replacement (TAVR). METHODS: Invasive hemodynamics via right heart catheterization (RHC) were performed pre-TAVR. Patients were stratified per mean PA pressure (mPAP), diastolic pulmonary gradient (DPG) and pulmonary vascular resistance (PVR), and followed at 1-month and 1-year intervals up to 6 years...
