Pulmonary hypertension is a disabling disease characterized by progressive functional worsening, right heart failure, and death. Although pulmonary hypertension has been associated with poor quality of life, sleep quality has not been investigated in pulmonary hypertension patients. This was a cross-sectional study in which patients (N = 40) were asked to complete standardized questionnaires to assess sleep quality [using Pittsburgh Sleep Quality Index (PSQI)], insomnia, sleepiness, dyspnea, depression, restless leg syndrome, and quality of life [using Cambridge Pulmonary Hypertension Outcome Review (CAMPHOR)] during routine office visits. Baseline hemodynamics, pulmonary function tests, exercise capacity, and transthoracic echocardiogram were analyzed. Pulmonary hypertension functional class was World Health Organization class II [20 (50%)], III [18 (45%)], and IV [2 (5%)], and 29 (72.5%) had poor sleep quality. PSQI score was associated with CAMPHOR symptoms score (R = 0.61, P < 0.001), CAMPHOR activities score (R = 0.38, P = 0.016), CAMPHOR quality-of-life score (R = 0.45, P = 0.004), depression (R = 0.42, P = 0.007), and dyspnea (R = 0.36, P = 0.02). Sleep quality was not associated with age, gender, other comorbidities, pulmonary hypertension etiology, baseline hemodynamics, pulmonary function testing, echocardiographic parameters, or exercise capacity. Poor sleep quality is common in patients with pulmonary hypertension and correlates with depression, dyspnea, and poor quality of life. Improving sleep quality in patients with pulmonary hypertension may improve quality of life.

Introduction Due to their stressful lives, Palestinian refugees are prone to use cognitive enhancers (CE) and psychostimulant substances (PS). Recognising health problems associated with CE/PS use can indicate how preventive programs should be directed towards adolescents. Unfortunately, research has not thoroughly investigated the health problems related to tobacco and caffeine products, the most socially acceptable CE/PS among Palestinian refugee adolescents. Methodology In 2021, schoolchildren from five Palestinian refugee camps (N=271) aged 12-<16 years agreed to give blood samples and to be interviewed to address the association between metabolic syndrome (MetS) and tobacco smoking, coffee, energy drinks (ED), black tea, and chocolate consumption. MetS was diagnosed based on International Diabetic Federation Criteria. To address the association, we used binary logistic regression models adjusted to age, gender, BMI, and central obesity. Results The prevalence of MetS was [17 (6.3%)]; (7.4%) in males, (5.1%) in females. The prevalence of substance use was as follows: ED [163 (48.9%)], coffee [255 (76.6%)], black tea [295 (89.1%)], cigarette [35 (10.5%)], waterpipe [59 (17.7%)], and chocolate [309 (93.6%)], with male predominance. Cigarette smokers have increased central obesity (p-value=0.024), and decreased HDL-cholesterol (p-value=0.015) than non-smokers. Similar results were observed for waterpipe smokers besides the increased levels of triglycerides (p-value=0.01). ED consumers have increased central obesity (p-value=0.03) and fast blood sugar (p-value=0.003) than non-consumers. Chocolate consumers have decreased central obesity (p-value=0.008) and increased HDL levels (p-value=0.04) than non-consumers. ED consumers were significantly at higher risk of MetS (OR=9.97, p-value=0.019) than non-consumers and chocolate consumers were at lower risk of MetS (OR=0.14, p-value=0.046) than non-consumers. Waterpipe smokers were at a higher risk of having increased plasma triglycerides than non-consumers (OR=3.4, p-value=0.03). Conclusion The high prevalence of ED consumption and waterpipe smoking in Palestinian refugee adolescents is problematic. Their use was associated with higher odds of MetS, dyslipidemia, and central obesity, which justifies greater attention.

Increased plasma brain natriuretic peptide (BNP) levels are associated with greater hemodynamic impairment, poorer functional capacity, and reduced survival in patients with idiopathic pulmonary arterial hypertension (PAH). 1,2BNP correlates with the degree of right ventricular overload and dysfunction in patients with PAH.3 Thus, BNP has assumed an increasingly important clinical role in the evaluation of patients with PAH. 4 -6 Compared to leaner subjects, BNP levels are attenuated in obese subjects with left ventricular dysfunction, even in the presence of heart failure symptoms and increased left ventricular filling pressure. [7][8][9] Nonetheless, in patients with left-sided heart failure, BNP remains a clinically useful predictor of exercise intolerance, hemodynamic impairment, and mortality at all levels of body mass index (BMI), although lower cutpoints appear necessary for patients with an elevated BMI.7,10 Whether a similar interaction between BNP and obesity occurs in subjects with PAH is not known. The present study investigated the relation between BNP and BMI in patients with PAH.

Many ocular conditions can occur in patients with lung transplants. Ocular infectious complications were uncommon but may be associated with increased mortality.
