Prognostic role of bronchial asthma in patients with heart failure

AbstractThere are few reports investigating the relationship between bronchial asthma (BA) and heart failure (HF). We hypothesized BA may have impact on prognosis in patients with HF. Among 323 consecutive outpatients with HF, 191 patients without chronic obstructive pulmonary disease were analyzed. Twenty patients had BA, most of whom (80.0%) had preserved left ventricular ejection fraction (LVEF  ≥ 50%). The use of β-blockers was less frequent (55.0% vs 83.0%.p = 0.01), systolic blood pressure (133 ± 22 vs 120 ± 17 mmHg,p = 0.003), and heart rate (83 ± 14 vs 74 ± 15 bpm,p = 0.02) were higher in patients with BA than those without BA. During median follow up of 24 months, 45 (23.6%) experienced primary outcome defined as a composite of all-cause death, nonfatal myocardial infarction, nonfatal ischemic stroke, and unexpected hospitalization due to HF. Multivariat e Cox regression analysis revealed that the presence of BA was independently associated with the occurrence of primary outcome (hazard ratio 3.08, 95% CI 1.42–6.71,p = 0.004). In the subgroup analysis of patients with preserved LVEF, patients with BA exhibited worse outcomes (p = 0.03 by log-rank). Patients with HF complicated by BA, most of whom had preserved LVEF, exhibited worse outcomes than those without BA.

This study characterized and compared the implementation of clinically integrated community health workers (CHWs) to a certified asthma educator (AE-C) for low-income children with asthma. In the AE-C arm (N = 115), 51.3% completed at least one in-clinic education session. In the CHW arm (N = 108), 722 home visits were completed. The median number of visits was 7 (range, 0-17). Scheduled in-clinic asthma education may not be the optimal intervention for this patient population. CHW visit completion rates suggest that the schedule, location, and content of CHW asthma services better met patients' needs. Seven to 10 visits s...

This study used 2013-2016 individual-level claims data of Iranian Health Insurance Organization in East Azerbaijan province. All ambulatory care utilizers were included in the study. We determined characteristics and utilization pattern of high-cost patients as well as their predictors. A total of 1 128 149 patients were included. The top 10% of patients accounted for 62.56% of the total expenditure. This skewed expenditure pattern remained relatively stable over the study period. Female sex, older age, cancer, chronic obstructive pulmonary disease, cardiovascular disease, and diabetes increase the odds of being high cost.

Authors: Chionh CY, Clementi A, Poh CB, Finkelstein FO, Cruz DN Abstract Heart failure (HF) is a major cause of morbidity and mortality. Extracorporeal (EC) therapy, including ultrafiltration (UF) and haemodialysis (HD), peritoneal dialysis (PD) and peritoneal ultrafiltration (PUF) are potential therapeutic options in diuretic-resistant states. This systematic review assessed outcomes of PD and compared the effects of PD to EC. A comprehensive search of major databases from 1966 to 2017 for studies utilising PD (or PUF) in diuretic-resistant HF was conducted, excluding studies involving patients with end-stage kidn...

ConclusionsThe present study demonstrates that IPEE treatments can enhance cerebral ischemic tolerance by regulating the toll-like receptor 4 (TLR4) signaling pathway. The mechanisms of this response come in two primary forms: inhibiting MyD88 dependent pro-inflammatory pathways and activating TRIF dependent anti-inflammatory pathways.Graphical abstract

ConclusionThe final results of this study showed that there was no significant difference between the four study groups and arrhythmia status. Therefore, f-QRS was not introduced as an independent predictor of arrhythmia in patients with acute MI.

Conclusions: Long-term exposure to NO2 and road traffic noise was associated with higher risk of heart failure, mainly among men, in both single- and two-pollutant models.
