Introduction: The alteration in serum lipid profile; increase in total cholesterol (TC), triacylglycerol (TAG), and low-density lipoprotein cholesterol (LDL-C); and reduction in high-density lipoprotein cholesterol (HDL-C) are key factors in cardiovascular disease progression. The high prevalence and severity of cardiovascular diseases require new screening tools for better evaluation. Atherogenic index (AI) (LDL-C/HDL-C) and coronary risk index (CRI) (TC/HDL-C) can be strong markers for predicting the risk of atherosclerosis and coronary heart disease and disclose the presence of LDL or TAG in the serum of related patients. To implement this strategy, the AIs and CRIs in our population were assessed. In this study, a total of 5207 subjects were recruited and AIs and CRIs were calculated for all of them. According to our data, age, body mass index, sex, as well as CRI and AI had affirmative correlation with TC, LDL-C, TAG, systolic blood pressure, and diastolic blood pressure. By increasing these factors, AIs and CRIs were augmented. Moreover, in situations where all atherogenic parameters are normal, these parameters may be the alternative screening tool.

Aluminum phosphide (AlP) is a very effective indoor and outdoor pesticide. We investigated the effects of N-acetyl cysteine (NAC) on the survival time, hemodynamics, and cardiac biochemical parameters at various time intervals in some cases of AlP poisoning. This research was a case–control study to evaluate 63 AlP poisoned patients during 2010–2012. Patients with cardiovascular complications of AlP to be treated with intravenous NAC plus conventional treatment were considered as the case group and compared with patients who did not receive NAC. NAC infusion was administered to the case group at 300 mg/kg for 20 h. The data gathered included age, sex, heart rate, Systolic blood pressure (SBP), creatine phosphokinase (CPK), creatine kinase MB (CK-MB), and ECG at the admission time and 12, 18, and 24 h after admission. Analysis of repeated measures was performed to check the variability of parameters over time. The mean ages in the case and control groups were 26.65 ± 1.06 (19–37 years) and 28.39 ± 1.11 (18–37 years), respectively (P = 0.266). Most of the patients were female (56.5%). CK-MB means were significantly different between the two groups, but no differences between the other variables were observed. Also, CK-MB, CPK, heart rate, and systolic blood pressure means became significantly different over time (0, 12, 18, and 24 h) in both groups (P < 0.001). NAC prevented sharp heart rate fluctuations in AlP patients in the case group. Regarding the outcomes, 17 patients died (10 patients in the control and 7 patients in the case groups). No side-effects of NAC were observed. Our patients could be managed by the positive role of NAC as the biochemical index of cardiotoxicity was found to elevate in both the case and control groups. Therefore, for the management protocol optimization, NAC evaluation should be done in further cases.

Background: Hypertension (HTN) is a major cause of noncommunicable diseases. In this study, we report the prevalence rate of HTN in Birjand population. Methods: This cross-sectional study was conducted on 1286 individuals in Birjand in 2014. Individuals with systolic blood pressure (SBP) ≥140 mmHg and/or diastolic blood pressure (DBP) ≥90 mmHg were considered as hypertensive. Data were analyzed using Chi-square test, independent t-test, and one-way ANOVA. P < 0.05 was considered as statistically significant. Results: Among the 1286 participants, 659 were women (51.2%). Prevalence of HTN was 20.1% (10.3% systolic HTN and 6.9% diastolic HTN). Prevalence self-reported HTN was 12.3%. SBP and DBP means were higher in men (P < 0.001). Mean scores of SBP and DBP increased by aging and body mass index (P < 0.001). Diabetic individuals had higher SBP scores (P < 0.001). Dyslipidemic patients had greater SBP and DBP (P < 0.001). Conclusions: Prevalence of HTN in our study is high. About one-fifth of the participants had HTN. In addition, BP is higher in men, elderly, and diabetic individual. Therefore, it is necessary to control BP regularly in different groups in society.

Backgrounds: A wide variety of factors such as individualistic and social/environmental factors appear to determine whether or not individuals can successfully quit substance use. In this study, Social Cognitive Theory was used as a theoretical framework to predict substance use abstinence among a sample of Iranian substance users. Methods: Data from 269 male substance users undergoing residential treatment were analyzed using logistic regression to assess the effects of socio-cognitive factors (treatment motivation, perceived social support, drug avoidance self-efficacy, and drug quitting outcome expectations) and background characteristics measured at 5–7 days after admission on drug abstinence status measured at 6-month follow-up. Results: Abstinence rate after 6-month follow-up was 48.6%. Perceived social support, treatment motivation, prior substance use treatment, and age of onset of substance use were predictors of abstinence. However, substance use treatment outcome was not influenced by drug avoidance self-efficacy, drug quitting outcome expectations, and demographic variables. Conclusion: Our findings do not support the notion that pretreatment drug avoidance self-efficacy and drug quitting outcome expectancies are among the most consistent predictors of substance use treatment outcome. Accordingly, future research is recommended to explore post-treatment levels of these variables on treatment outcome.

Background: Body mass index (BMI) is a known risk factor for renal cell cancer (RCC), but data are limited as to the effect of lifetime exposure to excess body weight. Methods: Using the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (N = 138,614, 527 incident RCCs), we identified several anthropometric measures to capture the lifetime BMI patterns: (i) BMI at specific ages; (ii) adulthood BMI trajectories; (iii) cumulative exposure to overweight/obesity denoted as weighted years of living overweight/obese (WYO); and (iv) weight change during each age span. We conducted multivariable Cox model to quantify the association between each anthropometric metric and incident RCC. Results: A higher BMI at ages 20 and 50 and at baseline was associated with a greater hazard of RCC. Compared with individuals who retained normal BMI throughout adulthood, we observed an increased hazard of RCC for BMI trajectory of progressing from normal BMI to overweight [HR, 1.49; 95% confidence interval (CI), 1.19–1.87], from normal BMI to obesity (HR, 2.22; 95% CI, 1.70–2.90), and from overweight to obesity (HR, 2.78; 95% CI, 1.81–4.27). Compared with individuals who were never overweight (WYO = 0), elevated HRs were observed among individuals who experienced low (HR, 1.31; 95% CI, 0.99–1.74), medium (HR, 1.57; 95% CI, 1.20–2.05), and high (HR, 2.10; 95% CI, 1.62–2.72) WYO tertile. Weight gain of ≥10 kg was associated with increased RCC incidence for each age span. Conclusions: Across the lifespan, being overweight/obese, weight gain, and higher cumulative exposure to excess weight were all associated with increased RCC risk. Impact: It is important to avoid weight gain and assess BMI from a life-course perspective to reduce RCC risk.
