The current meta-analysis aims to investigate the existing articles that evaluated the implications of a positive family history of cancer on the risk of colorectal cancer (CRC) within the EMRO countries. We employed PubMed, Scopus, and Web of Science as search databases for this study. To assess the quality of the selected articles, we utilized the Newcastle–Ottawa (NCO) checklist. In comparing the impact of a family history of cancer between the case and control groups, we computed the odds ratio (OR) along with its corresponding 95% confidence interval (CI). Finally, 27 articles were selected for meta-analysis. The result of the meta-analysis showed a significant association between the presence of a family history of CRC or any cancers and CRC (OR 2.21; 95% CI 1.54–3.17; P < 0.001, OR 1.76; 95% CI 1.27–2.42; P = 0.001, respectively). Our findings underscore the critical importance of timely screening and early identification for individuals with a family history of cancer. By fostering close coordination among healthcare facilities and actively promoting the adoption of screening methods for early detection, we have the potential to significantly reduce both mortality rates and financial burdens of CRC on the general public, ultimately leading to enhanced patient outcomes.

Background: Smoking poses a significant risk for colorectal cancer (CRC), considered the third leading reason for cancer-related deaths worldwide. However, there has been limited research on the relationship between smoking and CRC in the Eastern Mediterranean Regional Office (EMRO). Therefore, a meta-analysis was conducted to combine available data and gain a comprehensive understanding of the relationship between smoking and CRC in EMRO. Methods: Two independent researchers searched PubMed, Scopus, and Web of Science until December 2022. The included studies were checked for risk of bias administering the Newcastle-Ottawa scale. Heterogeneity was evaluated using I2 statistics and the Cochrane test. Publication bias was determined through funnel plot analysis and Egger's regression test. Additionally, a meta-regression analysis explored the impact of a country's Human Development Index (HDI) on the relationship between smoking and CRC. Results: The final analysis included 26 studies, revealing a significant association between smoking and CRC (OR = 1.40; 95% CI: 1.11 - 1.78; P = 0.004). Moreover, smoking had a more pronounced adverse effect on CRC in countries with higher HDIs compared to those with lower HDIs (OR = 1.30; 95% CI: 0.99 - 1.71; P = 0.054). Conclusions: Our findings underscore the importance of implementing smoking cessation programs and policies in EMRO countries, as they demonstrate a positive relationship between smoking and the risk of CRC. Furthermore, the results suggest that a country's level of human development may influence the association between smoking and CRC. Further research is needed to investigate this potential connection and develop targeted public health interventions. [ABSTRACT FROM AUTHOR]

Background: Bronchiectasis is a condition characterized by abnormal and permanent bronchial constriction that leads to sputum production and bronchial infection. The current study was done to evaluate the effects of symbiotic probiotics on the clinical manifestations and exacerbation of bronchiectasis. Materials and Methods: 26 patients in the placebo group (A) and 24 patients in the probiotic group (B) were allocated. In group A, patients took the placebo capsules two times daily for six months. In group B, patients took the LactoCare two times daily for six months. Results: The mean age of patients was 55.73±13.62 (group A) and 54.5±12.59 years (group B). Most of the patients had consumed azithromycin in both groups. The current study demonstrated there was no statistically significant difference between the decreased rate of pulmonary exacerbations in both groups. However, a decreasing trend was shown in the rate of pulmonary exacerbations without hospitalization (P=0.610). Also, there was a decreasing trend in the rate of pulmonary exacerbations leading to hospitalization (P=0.956). The most frequent etiologic pathogen was Pseudomonas sp. FEV1 and FVC/FEV1 ratios were higher in group B than in group A. However, there was no statistically significant difference between groups A and B (P=0.908 vs 0.403). Conclusion: The symbiotic probiotics were not effective in the clinical improvement of bronchiectasis, consumption of antibiotics, the rate of pulmonary exacerbations with or without hospitalization, FEV1 and FEV1/FVC, and microbiological pattern.
