RESUMEN
BACKGROUND: Although the benefits of breastfeeding are commonly approved, there remains a significant discrepancy between maternal practices and World Health Organization (WHO) guidelines in some countries. OBJECTIVES: We had two aims in this study; average duration of breastfeeding, and its maternal determinants. DATA SOURCES: A web-based citation index was used for citing documents. STUDY ELIGIBILITY CRITERIA AND PARTICIPANTS: We included observational studies evaluating breastfeeding duration among children who were at least two years old and not older than five were included in Iran. SYNTHESIS METHODS: The pooled mean and mean differences were considered. Heterogeneity was evaluated with the I2 statistic. RESULTS: The pooled mean of breastfeeding duration was calculated at 17.31 months. Children with younger mothers and lower birth orders had shorter durations of breastfeeding. Women with a high school and higher education level had early cessation of breastfeeding in comparison with less educated women. LIMITATIONS: The main limitation of the current study was lack of librarian assistance. CONCLUSIONS: The pooled mean of breastfeeding duration in Iranian children aged 2-5 was less than WHO recommendations. Accurate identification of the effect a mother's level of education has on duration of lactation requires standardized categorization. IMPLICATIONS OF KEY FINDINGS: Raising awareness among women can be an effective strategy in increasing the duration of lactation.

PROBLEM: Given the importance of exclusive breastfeeding (EB) duration on growth and to maintain health in children, we decided to systematically review the existing research on EB duration and its effect on the health of 2- to 5-year-old children in Iran. ELIGIBILITY CRITERIA: A systematic literature search was conducted in the Database of Abstracts of Reviews of Effects (DARE), Google Scholar, PubMed, Psyc INFO, Thomson Reuters, Cochrane, and Medical Library (MedLib) to detect appropriate studies (1994 to 2016). Outcomes of mean, mean difference, and proportions were pooled. SAMPLE: In this meta-analysis, 38 studies met the eligibility criteria. RESULTS: The pooled mean of EB was calculated as 4.1â¯months (CI 95%: 3.2, 4.99). The meta prevalence of EB up to 4â¯months and 5 to 6â¯months was estimated 65.0% (CI 95%: 54.0, 77.0) and 54% (CI 95%: 46.0, 62.0) respectively. Based on studies conducted over the years from 1994 to 2016, an increasing trend of EB was found in infants up to 4â¯months (pâ¯≤â¯0.0001). Among children with anemia and respiratory diseases EB until 5 to 6â¯months was more common than in healthy children (CI 95%; 1.1, 2.11, and 1.01, 1.47 respectively). CONCLUSION: The duration of EB (4.1â¯months) was equal to the lower limit recommended by the World Health Organization (WHO). Overall, the duration of EB until 5 to 6â¯months is sufficient if the child's iron intake is well-monitored. IMPLICATION: Monitoring of the implementation of recent guidelines or even modification of the duration period of the iron administration is potentially necessary.

Opioid abuse is a serious problem in the society. Since the first months of COVID-19 pandemic, several myths, rumors and misconceptions have been spread about the benefits of opium consumption for COVID-19 outcome. In addition, data are limited on the relationship between opium abuse and COVID-19 mortality amongst hospitalized COVID-19 patients. In this historical cohort study, we assessed the risks of several variables for mortality amongst all hospitalized COVID-19 patients from the beginning of COVID-19 pandemic in South of Iran from March 15th, 2021 to October 14th, 2021. Data was acquired from the Medical Care Monitoring Center (MCMC), affiliated to Shiraz University of Medical Sciences. A total of 64,427 hospitalized COVID-19 patients were included into the analysis. The mortality rate was 10.59% (n = 6756). Of all, 2030 (3.15%) patients-1702 males and 328 females-reported the positive history of opium abuse with a mean age of 57 ± 17.21 years. The results of multivariable risk showed that the positive history of opium abuse had a significant association with mortality (adjusted RR: 1.173; p = 0.007). Other significant predictive risk factors were male gender, elder ages, and comorbidities such as pulmonary diseases, cardiovascular disease, cancer, nephrological diseases, neurological diseases, and diabetes. However, being a health care worker and having thyroid gland diseases were protective factors amongst hospitalized COVID-19 patients (adjusted RR: 0.650 and 0.642; p = 0.040 and < .0001, respectively). Opium abuse is a risk factor for mortality amongst hospitalized COVID-19 patients. It is vital to educate societies about the consequences of unauthorized opium consumption.

INTRODUCTION: Prevention of pulmonary complications after coronary artery bypass graft is attended as a very important issue. The aim of this study was to evaluate the role of pulmonary rehabilitation before surgery for reducing the risk of pulmonary complications after surgery. METHODS: In a randomized clinical trial, 60 patients undergoing heart surgery were randomly divided into two groups A and B. Chest physiotherapy was performed before and after surgery on group A patients however it was done on group B's, only after surgery. Effects of preoperative pulmonary rehabilitation were compared between two groups, using spirometry and arterial blood gas (ABG). RESULTS: Thirty nine males (65%) and 21 females (35%) with mean age of 8.10 ± 9.56 were analyzed. The mean differences were statistically significant for predicted forced vital capacity (FVC) (CI 95%:1.3 to 8.7) and Predicted Peak Flow indices (PEF) (CI 95%: 1.9 to 9.4) of spirometry indicator, PCO2 index (of ABG parameter) (CI 95%: 1.4 to 8.9) and mean oxygen saturation (mean Spo2) (CI 95%: 0.6 to 1.7) of ABG index in two groups. CONCLUSION: The performance of pulmonary rehabilitation program before surgery is recommended, as it may result in the reduction of complications of heart surgery.
