Phosphodiesterase inhibitor for heart failure with preserved ejection fraction: A systematic review and meta-analysis.

Background: Although heart failure with preserved ejection fraction (HFpEF) is a serious disease, only limited options are available for its treatment. Recent studies have analyzed the effects of phosphodiesterase (PDE) inhibitors, especially PDE5 and PDE3 inhibitors, in patients with HFpEF, with mixed outcomes. Methods: We searched PUBMED and EMBASE databases up to August 2021. Randomized controlled trials (RCTs) and clinical trials that tested the effects of PDE inhibitors on patients with HFpEF were included as eligible studies. Indicators of left ventricular (LV) function, pulmonary arterial pressure (PAP), right ventricular (RV) function, exercise capacity, and quality of life (QOL) were used to evaluate the efficacy of PDE inhibitors in HFpEF. Results: Six RCTs that reported in 7 studies were included to evaluate the efficiency of PDE inhibitors on HFpEF patients. In the pooled analysis, PDE inhibitors showed insignificant changes in the ratio of early diastolic mitral inflow to annular velocities, left atrial volume index, pulmonary artery systolic pressure (PASP), pulmonary vascular resistance (PVR), peak oxygen uptake, 6-minute walking test distance, as well as Kansas City Cardiomyopathy Questionnaire score. However, substantial improvement was observed in the tricuspid annular plane systolic excursion (TAPSE). Additionally, the regression analysis showed that PDE inhibitor administration time is a critical factor for the decrease in PASP. Conclusions: PDE inhibitors did not effectively improve LV function, PAP, exercise capacity, and QOL in patients with HFpEF. However, they improved RV function with significant difference, suggesting that PDE inhibitors might be a promising option for HFpEF patients with RV dysfunction.

Longitudinal changes in employment following a diagnosis of endometriosis: Findings from an Australian cohort study.

PURPOSE: Endometriosis is a chronic inflammatory disease affecting the reproductive, gastrointestinal, and urinary systems. We examined changes in labor force participation amongst women with endometriosis following diagnosis. METHODS: We analyzed data from 4494 women born in 1973-78 from the Australian Longitudinal Study on Women's Health. We used multinomial logistic regression models with generalized estimating equations to examine changes in labor force participation amongst 468 women with surgically confirmed endometriosis, and 375 women with clinically suspected endometriosis, relative to a comparison group of 4151 women without endometriosis. RESULTS: At diagnosis, women with surgically confirmed endometriosis were somewhat more likely to be working part-time (OR 1.26, 95% CI 0.94-1.68) or unemployed (OR 1.46, 95% CI 0.96-2.23) than before diagnosis. After diagnosis, women with surgically confirmed endometriosis remained somewhat more likely to be working part-time (OR 1.26, 95% CI 0.88-1.80) but were significantly more likely to be unemployed (OR 1.85, 95% CI 1.16-2.96) than before diagnosis. Labor force participation for women with clinically suspected endometriosis did not differ from women without endometriosis at diagnosis and did not change over time. CONCLUSIONS: Women with surgically confirmed endometriosis transitioned out the labor force following diagnosis. Supportive workplace practices may help women remain in the labor force.

Efficacy of pharmacologic treatment in tinnitus patients without specific or treatable origin: A network meta-analysis of randomised controlled trials.

BACKGROUND: Although tinnitus has a prevalence between 20 and 42.8%, the currently recommended management for tinnitus, such as tinnitus support and psychologic therapies, are relatively time-consuming and expensive. Several new pharmacologic treatments designed for tinnitus patients without specific origin had been developed but their efficacy remains unclear. METHODS: The current Network Meta-Analysis (NMA) of randomised controlled trials (RCTs) was conducted to evaluate the efficacy of different pharmacologic treatments for tinnitus management in tinnitus patients without specific or treatable origin (i.e. primary tinnitus). Databases were searched from inception to April 5th, 2021. All network meta-analytic procedures were conducted under the frequentist model. We calculated the effect size of outcomes with different rating scales with standardized mean difference. PROSPERO registration: CRD42020177742. FINDINGS: Overall, 36 RCTs were included with 2,761 participants. The main results revealed that pharmacologic interventions with brain-acting effect (for example, amitriptyline, acamprosate, and gabapentin) and those with anti-inflammation/anti-oxidant effect (for example, intra-tympanic dexamethasone injection plus oral melatonin) were associated with superior improvement in tinnitus severity and response rate compared to placebo/control. Oral amitriptyline were associated with the highest improvement in tinnitus severity and the fourth highest response rate. None of the investigated interventions was associated with different changes in quality of life compared to placebo/control. All the investigated treatments were associated with similar drop-out rate to placebo/control. INTERPRETATION: The current NMA suggests a potential role for treatments with brain-acting effect (for example, amitriptyline, acamprosate, and gabapentin) or anti-inflammation/anti-oxidant effect (for example, intra-tympanic dexamethasone injection plus oral melatonin) as the preferable effective treatments for tinnitus without specific or treatable origin. FUNDING: none.
