The associations of religiosity and family atmosphere with lifestyle among Saudi adolescents.

There have been gradual sociocultural changes in Saudi Arabia due to globalization. This allows a unique opportunity to examine religiosity and family atmosphere in relation to lifestyle among Saudi adolescents. In this cross-sectional study, 2067 school students (grades 7-12) from 32 randomly selected schools in Al-Qassim, Saudi Arabia were enrolled. Perceived religiosity, family atmosphere, lifestyle (e.g., physical activity, diet, screen time, obesity, and smoking), demography, parental attributes, and religious practices were assessed with validated scales and questions. A risk profile was created from the lifestyle variables (none, one, two, or ≥ three), and the students were grouped into low versus high religiosity and low versus high family atmosphere using a median split. Multinomial regressions were used to model the lifestyle risk profile. The mean age ±standard deviation was 15.5 years ±1.7, and 35% were girls; 28% had no risk factors, 32% had one, 25% had two, and 15% had ≥3. After adjustment, both low religiosity and low family atmosphere were significant correlates of the lifestyle risk profile (e.g., ≥3 risk factors: religiosity OR = 2.9, 95% CI: 2.1, 4.0; family atmosphere OR = 2.0, 95% CI: 1.5, 2.8). Those with both low religiosity and low family atmosphere were more likely to have a higher lifestyle risk profile than those who scored high in religiosity and better in family atmosphere (e.g., ≥3 risk factors: OR = 5.9, 95% CI: 3.7, 9.5). Hence, higher religiosity and better family atmosphere are associated with less risky lifestyles among Saudi adolescents.

Physiologic assessment of moderate coronary lesions: a step towards complete revascularization in coronary artery bypass grafting.

BACKGROUND: An accurate diagnostic assessment of coronary artery disease is crucial for patients undergoing coronary artery bypass grafting (CABG). Fractional flow reserve (FFR) and instantaneous wave-free ratio (iFR) to guide complete revascularization have not been adequately studied in patients prior to CABG. We compared an anatomic to a physiologic assessment of moderate coronary lesions (40-70% stenosis) in patients referred for CABG. METHODS: We retrospectively reviewed 109 medical records of patients who underwent CABG at Tulane Medical Center from 2014 to 2016. Patients were divided into an FFR/iFR-guided and an angiography-guided group. Clinical characteristics, procedural outcomes, and clinical outcomes for the two groups were compared over an 18-month follow-up period. RESULTS: There were significantly higher rates of three-vessel anastomoses (85.7% vs. 74.7%, P<0.05) and venous grafting (85.7% vs. 76.8%, P<0.05) in the FFR/iFR group. The FFR/iFR group had a lower rate of grafts placed to the left anterior descending artery (LAD) distribution than the angiography group (7.1% vs. 29.5%, P<0.05). The FFR/iFR group had a higher rate of grafts placed to the left circumflex (LCx) artery distribution than the angiography group (28.6% vs. 9.5%, P<0.05). We observed a trend toward reduction in major adverse cardiac events (MACEs) (7.1% vs. 11.6%, P=0.369) and angina (0.0% vs. 6.3%, P=0.429) in the FFR/iFR group compared to the angiography group over 18 months. CONCLUSIONS: Physiologic assessment of coronary lesions can effectively guide complete revascularization in patients undergoing CABG. Moreover, FFR/iFR-guided CABG was associated with significantly higher rates of three-vessel anastomoses, venous grafting, and graft distribution to the circumflex system.

Instantaneous wave-free ratio as an alternative to fractional flow reserve in assessment of moderate coronary stenoses: A meta-analysis of diagnostic accuracy studies.

BACKGROUND/PURPOSE: Fractional flow reserve (FFR) remains underutilized due to practical concerns related to the need for hyperemic agents. These concerns have prompted the study of instantaneous wave-free ratio (iFR), a vasodilator-free index of coronary stenosis. Non-inferior cardiovascular outcomes have been demonstrated in two recent randomized clinic trials. We performed this meta-analysis to provide a necessary update of the diagnostic accuracy of iFR referenced to FFR based on the addition of eight more recent studies and 3727 more lesions. METHODS: We searched the PubMed, EMBASE, Central, ProQuest, and Web of Science databases for full text articles published through May 31, 2017 to identify studies addressing the diagnostic accuracy of iFR referenced to FFR≤0.80. The following keywords were used: "instantaneous wave-free ratio" OR "iFR" AND "fractional flow reserve" OR "FFR." RESULTS: In total, 16 studies comprising 5756 lesions were identified. Pooled diagnostic accuracy estimates of iFR versus FFR≤0.80 were: sensitivity, 0.78 (95% CI, 0.76-0.79); specificity, 0.83 (0.81-0.84); positive likelihood ratio, 4.54 (3.85-5.35); negative likelihood ratio, 0.28 (0.24-0.32); diagnostic odds ratio, 17.38 (14.16-21.34); area under the summary receiver-operating characteristic curve, 0.87; and an overall diagnostic accuracy of 0.81 (0.78-0.84). CONCLUSIONS: In conclusion, iFR showed excellent agreement with FFR as a resting index of coronary stenosis severity without the undesired effects and cost of hyperemic agents. When considering along with its clinical outcome data and ease of application, the diagnostic accuracy of iFR supports its use as a suitable alternative to FFR for physiology-guided revascularization of moderate coronary stenoses. SUMMARY: We performed a meta-analysis of the diagnostic accuracy of iFR referenced to FFR. iFR showed excellent agreement with FFR as a resting index of coronary stenosis severity without the undesired effects and cost of hyperemic agents. This supports its use as a suitable alternative to FFR for physiology-guided revascularization of moderate coronary stenoses.

Safety and efficacy of everolimus-eluting bioresorbable vascular scaffolds versus durable polymer everolimus-eluting metallic stents assessed at 1-year follow-up: A systematic review and meta-analysis of studies.

BACKGROUND: The Absorb bioresorbable vascular scaffold (BVS) was developed to address long-term safety issues of metallic drug-eluting stents. However, it may be associated with an increased event risk during the first year. METHODS: A systematic literature search was performed (in MEDLINE/PubMed, Cochrane CENTRAL, EMBASE, and scientific meeting abstracts) to identify studies that compared BVS and cobalt-chromium durable polymer everolimus-eluting stents (EES). For randomized clinical trials and non-randomized propensity score matched studies that reported 1-year outcome data, fixed/random-effects models were used to generate pooled estimates of outcomes, presented as odds ratios (OR) with 95%-confidence intervals (CI). RESULTS: The 1-year follow-up data of 6 trials with 5588 patients were analyzed. A device-oriented composite endpoint (DOCE - cardiac death, target vessel myocardial infarction (MI), or target lesion revascularization (TLR)) was reached by 308 BVS or EES patients (195/3253 vs. 113/2315). Meta-analysis showed that patients who received BVS had an increased risk of MI (4.3% vs. 2.3%; OR:1.63, 95%-CI: 1.18-2.25, p<0.01) and definite-or-probable scaffold thrombosis (1.3% vs. 0.6%; OR:2.10, 95%-CI: 1.13-3.87, p=0.02). However, there was no significant between-group difference in risk of DOCE (6.0% vs. 4.9%; OR:1.19, 95%-CI: 0.94-1.52, p=0.16), cardiac death (0.8% vs. 0.7%; OR:1.14, 95%-CI: 0.54-2.39, p=0.73), or TLR (2.5% vs. 2.5%; OR: 0.98, 95%-CI:0.69-1.40, p=0.92). CONCLUSIONS: During the first year of follow-up, patients treated with BVS had a higher incidence of MI and scaffold thrombosis. The risk of DOCE was not significantly different. As BVS may pay off later, future robust data on long-term clinical outcome will be of paramount importance.

Epidemiology of Malignant and Non-Malignant Primary Brain Tumors in Jordan.

BACKGROUND: There is lack of knowledge on the epidemiological characteristics of brain tumors in Middle Eastern countries. The objective of this study was to study the epidemiological features of primary brain tumors in Jordan. METHODS: We conducted a prospective cohort study incorporating data from 16 hospitals in Jordan during a 1 year period (May 1, 2011-April 30, 2012). All primary brain tumors diagnosed in Jordan during the study period were identified. The following parameters were retrieved from patients' files: age, gender, histological type, and location. The demographic data of the country was obtained from the National Department of Statistics. RESULTS: A total of 313 primary brain tumors were identified during the study period. The incidence of primary brain tumors in Jordan among the general population was 5.01 per 100,000 person-years (5.38 in females and 4.65 in males). The incidence in pediatric, adult, and elderly patients was 2.09, 7.29, and 14.38 per 100,000 person-years, respectively. The most common histological types were meningioma (26.2%), glioblastoma (18.9%), astrocytoma (14.1%), and pituitary adenoma (9.3%). CONCLUSIONS: The incidence of primary brain tumors in the Jordanian population is relatively low, in part due to the young age of the general population.

Stress Cardiomyopathy in the Setting of COPD Exacerbation.

Introduction. Stress cardiomyopathy, or takotsubo cardiomyopathy, is an acute, reversible left ventricular dysfunction usually initiated by a psychological or physical stress. We report this case of stress cardiomyopathy following a chronic obstructive pulmonary disease exacerbation and the subsequent treatment. Case Description. A 49-year-old white female with a history of chronic obstructive pulmonary disease presented to the emergency room via emergency medical services with worsening severe shortness of breath and productive cough for 2 weeks but denied any chest pain on arrival. On presentation, she was noted to be tachypneic, using her accessory muscles and with bilateral coarse expiratory wheezing on lung auscultation. Initial electrocardiogram demonstrated sinus tachycardia. She was treated with multiple albuterol treatments. Soon afterwards, the course was complicated by hypoxic respiratory failure eventually requiring intubation. Her repeat electrocardiogram showed acute changes consistent with myocardial infarction, and an echocardiograph demonstrated apical akinesia with an ejection fraction of 25% to 30%. The patient was urgently taken for cardiac catheterization, which showed no angiographic evidence of coronary artery disease. Three days after initial presentation, a repeat transthoracic echocardiogram showed overall left ventricular systolic function improvement. Discussion. This case provided a unique look at the difficulty of balancing catecholamines in a patient with bronchospasm and stress cardiomyopathy.
