Knowledge and skill level among non-healthcare providers regarding cardiopulmonary resuscitation (CPR) training in the Middle East (Arab countries): a systematic review and meta-analysis.

BACKGROUND: Effective education is considered by the American Heart Association (AHA) as a vital variable in improving outcomes of cardiac arrest. Studies have shown that the level of knowledge and attitude of non-healthcare providers towards resuscitation training varies widely across the globe. While some training methods and barriers to training have been discussed, the literature is still quite vague and unclear regarding resuscitation training, particularly in the Middle East. This study's focus on the efficacy of resuscitation training in this region of the world may help dictate how to better implement education initiatives aimed towards non-healthcare providers in developing countries. METHODOLOGY: A systematic review and meta-analysis were conducted on studies published from inception until March 2023. Observational studies assessing CPR knowledge and skills among non-healthcare workers in Arab countries were included. Data were extracted from PubMed, Cochrane Library, EMBASE, Web of Science, and Scopus. Data analysis was performed using Rstudio with a random effects model. RESULTS: 50 studies were included in this review and meta-analysis, revealing that 55% of participants had prior knowledge of CPR, while only 28% considered their knowledge sufficient. The majority (76%) supported mandatory CPR training, and 86% were willing to attend training if offered. This study found that prior knowledge of cardiopulmonary resuscitation (CPR) varied among populations. This meta-analysis also compiled results regarding CPR technique defined by correct compression to ventilation ratio, compression depth, compression rate, location of chest compression, and correct sequence. The overall results from this meta-analysis showed that, of these factors, compression rate and depth were the two factors that were most often administered incorrectly. In all, the results from this study demonstrated that CPR training in Arab countries was favorably viewed overall, with the majority of participants indicating both support for mandatory CPR training and general willingness to attend training if offered the opportunity. CONCLUSION: Given the overall positive view and willingness to learn CPR skills, healthcare policy makers should adopt a more comprehensive focus on strategies that enhance the accessibility and opportunity for CPR training for non-healthcare populations in Arab countries. Future training programs should implement strategies to highlight the ideal combination of compression rates and depth to learners to ensure correct and efficacious delivery of CPR with increased focus on the practical portion during refresher courses to promote retention.

Safety and efficacy of edaravone in patients with amyotrophic lateral sclerosis: a systematic review and meta-analysis.

AIM: The study aims to increase understanding of edaravone's efficacy and safety as an amyotrophic lateral sclerosis (ALS) treatment and provide significant insights regarding this field's future research. METHODS: We conducted a comprehensive search of the Embase, PubMed, Cochrane Library, Web of Science, and Scopus databases for randomized controlled trials and observational studies up until September 2022. We evaluated the studies' quality using the Cochrane risk of bias tool and the National Institutes of Health tool. RESULTS: We included 11 studies with 2845 ALS patients. We found that edaravone improved the survival rate at 18, 24, and 30 months (risk ratio (RR) = 1.03, 95% confidence interval (CI) [1.02 to 1.24], P = 0.02), (RR = 1.22, 95% CI [1.06 to 1.41], P = 0.007), and (RR = 1.17, 95% CI [1.01 to 1.34], P = 0.03), respectively. However, the administration of edaravone did not result in any significant difference in adverse effects or efficacy outcomes between the two groups, as indicated by a P value greater than 0.05. CONCLUSION: Edaravone improves survival rates of ALS patients at 18, 24, and 30 months with no adverse effects. However, edaravone does not affect functional outcomes. In order to ensure the validity of our findings and assess the results in accordance with the disease stage, it is essential to carry out additional prospective, rigorous, and high-quality clinical trials. The current study offers preliminary indications regarding the effectiveness and safety of edaravone. However, further comprehensive research is required to establish the generalizability and sustainability of the findings.

Efficacy of Hibiscus sabdariffa on Reducing Blood Pressure in Patients With Mild-to-Moderate Hypertension: A Systematic Review and Meta-Analysis of Published Randomized Controlled Trials.

We aimed to assess the efficacy of Hibiscus sabdariffa in patients with mild-to-moderate hypertension or metabolic syndrome (MetS) by comparing it against placebo, antihypertensive drugs, or other herbal products. Four databases were searched for randomized clinical trials (RCTs) examining the efficacy of H. sabdariffa in patients with mild-to-moderate hypertension or hypertension associated with MetS. Data on the change in systolic blood pressure (SBP) and diastolic blood pressure (DBP) were extracted and analyzed using Review Manager Version 5.3. A total of 13 RCTs (1205 participants) were analyzed. Hibiscus sabdariffa significantly reduced both SBP and DBP compared with placebo (mean difference -6.67, P = 0.004 and -4.35 mm Hg, P = 0.02). Subgroup analysis showed that change in SBP and DBP was statistically significant in patients with only hypertension, whereas not significant in patients with hypertension associated with MetS. When H. sabdariffa was compared with active controls (antihypertensive drugs or other herbals), the change in SBP and DBP was not statistically significant (all P > 0.05). Hibiscus sabdariffa is effective in reducing the SBP and DBP in patients with mild-to-moderate hypertension, but was neither effective in those with MetS nor superior to antihypertensive drugs. Further RCTs are required to determine the long-term efficacy of H. sabdariffa and to describe patients who would benefit most from this treatment.

Maternal and neonatal safety outcomes after SAR-CoV-2 vaccination during pregnancy: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: More than five million individuals died because of problems connected to COVID-19. SARS-Cov-2 poses a particular challenge to expectant mothers, who comprise one of the most vulnerable segments of the population. Our aim is to demonstrate the maternal and neonatal safety of the COVID-19 vaccine during pregnancy. METHODS: We searched PubMed, Cochrane Library, Scopus, Web of Science (WOS), Embase, Ovid, MedRxiv, and BioRxiv databases from inception till December 2021 and then updated it in April 2022. Additionally, we searched ClinicalTrials.gov, Research Square and grey literature. Cohort, case-control studies, and randomized controlled trials detecting the safety of the Covid-19 vaccine during pregnancy were included. We used the Cochrane tool and Newcastle-Ottawa Scale to assess the risk of bias of the included studies and the GRADE scale to assess the quality of evidence. A meta-analysis was conducted using review manager 5.4. RESULTS: We included 13 studies with a total number of 56,428 patients. Our analysis showed no statistically significant difference in the following outcomes: miscarriage (1.56% vs 0.3%. RR 1.23; 95%CI 0.54 to 2.78); length of maternal hospitalization (MD 0.00; 95%CI -0.08 to 0.08); puerperal fever (1.71% vs 1.1%. RR 1.04; 95%CI 0.67 to 1.61); postpartum hemorrhage (4.27% vs 3.52%. RR 0.84; 95%CI 0.65 to 1.09); instrumental or vacuum-assisted delivery (4.16% vs 4.54%. RR 0.94; 95%CI 0.57 to 1.56); incidence of Apgar score ≤ 7 at 5 min (1.47% vs 1.48%. RR 0.86; 95%CI 0.54 to 1.37); and birthweight (MD -7.14; 95%CI -34.26 to 19.99). CONCLUSION: In pregnancy, the current meta-analysis shows no effect of SAR-CoV-2 vaccination on the risk of miscarriage, length of stay in the hospital, puerperal fever, postpartum hemorrhage, birth weight, or the incidence of an Apgar score of ≤ 7 at 5 min.

Prevalence and patterns of premenstrual disorders and possible association with sexual harassment: a cross-sectional study of young Arab women.

BACKGROUND: Premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD) represent a range of both psychiatric and physical symptoms that impair quality of life and interfere with daily activities in females. AIMS: To assess the prevalence of PMS and PMDD in Egypt, Jordan and Syria, its demographic associations and the potential link to sexual harassment (SH). METHODS: We used an Arabic version of the premenstrual symptoms screening tool (PSST) to assess the prevalence of PMS and PMDD. Another two-part questionnaire was used to assess the harassment experience. RESULTS: 22,021 women agreed to fill the questionnaire; the majority (65%) aged 18-25 years old. PMS was more prevalent in Egyptian women 77.7% followed by women from Jordan 72.9% then Syria 66.3%. PMDD prevalence followed the same order (40%, 34.7% and 28.2%). Both conditions were significantly associated with obesity and working in medical careers (P = .001). 5733 women agreed to share their sexual harassment experience. Results showed a significant association between the diversity and frequency of sexual harassment and the frequency of the pre-menstrual conditions, PMS Frequency was 87.6%, 80.7% and 78% in participants who were harassed on daily basis Vs. once weekly or monthly vs. few times in their lifetime (p = .04). A similar statistically significant difference was noticed regarding having PMDD (66.4% vs. 47.6% vs. 42.5%). CONCLUSION: The study showed high levels of both PMS and PMDD. The data provided by this study also sheds light on a potential link between SH and developing Pre-menstrual disorders.

Public knowledge, attitude, and acceptance toward COVID-19 vaccines in Palestine: a cross-sectional study.

BACKGROUND: The consequences of the COVID-19 pandemic on physical and mental health in addition to the global economy are huge. Vaccination is a pivotal measure to decrease COVID-19 morbidity and mortality and to help bring the pandemic under control. Yet, success of the vaccination process depends on the population's willingness to be vaccinated which may be determined by their level of knowledge about and trust in currently available COVID-19 vaccines. Therefore, this study aims to assess the knowledge, attitude, and acceptance of Palestinians towards COVID-19 vaccines. METHODS: A national cross-sectional study was distributed in different Palestinian regions to assess the knowledge and attitude of Palestinians toward COVID-19 vaccines using an online questionnaire, it included three sections; sociodemographic characteristics, knowledge assessment questions, and attitude assessment questions. RESULTS: A total of 6226 participants completed the questionnaire; among them, 41.36% believed that vaccines are safe, 69.02% agreed that vaccines are vital to protect from COVID-19; in addition, 55.1% approve administering the vaccine once available, and 37.86% do not believe their benefits outweigh the risks. The Source of information for 22.07% of participants in social media, while 11.92% rely on health care providers. Participants' attitudes and knowledge were significantly affected by gender, governorate, age, education level, and marital status (P <0.001). CONCLUSION: The findings suggest that there is good knowledge and attitude toward the vaccination process against COVID-19 in Palestine, although low acceptance was detected. Awareness campaigns are required to spread reliable knowledge about COVID-19 vaccines.

Knowledge, attitudes, practices and perceived barriers towards research in undergraduate medical students of six Arab countries.

BACKGROUND: The involvement of the undergraduates in the research field requires a better view of their potential and the anticipated barriers facing them. This study aims to assess the undergraduates' knowledge, attitudes, practices and perceived barriers towards research in six Arab countries. METHODS: A cross sectional study included medical students from six Arab countries, where a self-administered five-section questionnaire was used to assess the students' demographics, knowledge, attitudes, practices and perceived barriers. The questionnaire was distributed in the online educational platforms of the participating medical schools in the six included countries. RESULTS: The total sample of recruited students was 2989, the majority of students (91.6%) showed poor level of knowledge regarding research. Generally high levels of positive attitudes towards research, research relevance and usefulness were found, with moderate levels of perception of research anxiety and difficulty. 33.7% (n = 1006) participated in an actual research project before with a mean of .5 publications per student. Cross-sectional studies were the most common type of studies conducted by students (38.6%), followed by case reports (23.9%). Lack of access to lab equipment for lab research (68.1%), the priority of education over research (66.8%), and lack of time because of educational tasks (66.1%) were generally the top perceived barriers towards research practice. CONCLUSION: In the current study, the participants showed a poor knowledge level with associated positive attitudes towards research. One third of the students participated in research projects that mostly were cross-sectional studies and case reports. Educational tasks and lack of support were the most prevalent barriers. The students' positive attitudes towards research need to be translated into better knowledge and appropriate practice, which can be done by development of better training systems and more structured mentoring.

Risk factors for suicide mortality and cancer-specific mortality among patients with gastric adenocarcinoma: A SEER based study.

OBJECTIVE: This study aims to investigate the risk factors for suicide in patients with gastric adenocarcinoma (GAC) to recognize patients at higher risk who require special mental health care. METHODS: Patients' data were collected from the Surveillance, Epidemiology, and End Results database from 1975 to 2016. The relationships among categorical variables were assessed using Person's chi-square test. Standardized mortality ratio was used to compare ratios of suicide and other causes of death between the US population and adenocarcinoma patients. Cox regression and Kaplan-Meier were used for multivariate and univariate analyses. The probability of suicide was assessed using the binary regression analysis. All analyses were conducted using SPSS software. RESULTS: Among 59,580 patients included in this study, 86 died due to suicide. The mean survival months was higher in patients <50 years (81.759) than in patients ≥50 years (42.961), and in females (49.116) than in males (44.591). The multivariate analysis showed a higher suicide mortality risk in divorced patients (HR = 2.461; 95% CI [1.015, 5.966], p = 0.046), patients not recommended for surgery (HR = 1.997; 95% CI [1.08, 3.694], p = 0.027) and patients with distant stage of the disease (HR = 2.68; 95% CI [1.395, 5.147], p = 0.003). Females had a lower suicide mortality risk (HR = 0.124; 95% CI [0.045, 0.314], p < 0.001). CONCLUSION: GAS predisposes to suicide. The risk is higher in patients who are males, divorced, not recommended for surgery, or have a distant spread of the disease.

Lithium carbonate as add-on therapy to radioiodine in the treatment on hyperthyroidism: a systematic review and meta-analysis.

BACKGROUND: The main purpose is to investigate the effect of LiCO3 as an add-on therapy with radioactive iodine in increasing the cure and decreasing the T4 level compared to radioactive iodine alone. The primary outcome is the cure rate as defined by the number of hyperthyroid patients who became euthyroid or hypothyroid. The secondary outcome is the T4 level. METHODS: Four databases were searched (PubMed, Scopus, Web of Science, and Cochrane central library). The inclusion criteria were randomized and non-randomized clinical trials of hyperthyroidism patients receiving LiCO3 with radioiodine compared with hyperthyroidism patients receiving radioactive iodine alone. Included studies were appraised with the risk of bias version 2 tool, according to the Cochrane Handbook for Systematic Reviews of Interventions 5.1.0. RESULTS: Nine studies were eligible for inclusion in the study, six randomized control trials and three non-randomized control trials. There were 477 patients in the intervention group and 451 patients in the control group. The cure rate was not significantly different between the two groups, while it was significantly increased with 5000 to 6500 mg optimized cumulative dose of LiCO3 compared with the control group, P = 0.0001. The T4 level showed no significant difference between the two groups, P = 0.13. CONCLUSIONS: LiCO3 adjunct to radioactive iodine did not show significant differences compared with radioactive iodine alone in terms of cure rate or decreasing T4 level. However, the dose of 5000 to 6000 mg of LiCO3 may increase the cure rate.

Chest pain in pediatric patients in the emergency department- Presentation, risk factors and outcomes-A systematic review and meta-analysis.

OBJECTIVE: This study aimed to assess and determine the presentation, risk factors, and outcomes of pediatric patients who were admitted for cardiac-related chest pain. BACKGROUND: Although chest pain is common in children, most cases are due to non-cardiac etiology. The risk of misdiagnosis and the pressure of potentially adverse outcomes can lead to unnecessary diagnostic testing and overall poorer patient experiences. Additionally, this can lead to a depletion of resources that could be better allocated towards patients who are truly suffering from cardiac-related pathology. METHODS: This review was conducted per PRISMA guidelines. This systematic review used several databases including MEDLINE, Embase, Scopus, and Web of Science to obtain its articles for review. RESULTS: A total of 6,520 articles were identified, and 11 articles were included in the study. 2.5% of our study population was found to have cardiac-related chest pain (prevalence = 0.025, 95% CI [0.013, 0.038]). The most commonly reported location of pain was retrosternal chest pain. 97.5% of the study population had a non-cardiac cause of chest pain, with musculoskeletal pain being identified as the most common cause (prevalence = 0.357, 95% CI [0.202, 0.512]), followed by idiopathic (prevalence = 0.352, 95% CI [0.258, 0.446]) and then gastrointestinal causes (prevalence = 0.053, 95% CI [0.039, 0.067]). CONCLUSIONS: The overwhelming majority of pediatric chest pain cases stem from benign origins. This comprehensive analysis found musculoskeletal pain as the predominant culprit behind chest discomfort in children. Scrutinizing our study cohort revealed that retrosternal chest pain stands as the unequivocal epicenter of this affliction. Thorough evaluation of pediatric patients manifesting with chest pain is paramount for the delivery of unparalleled care, especially in the context of potential cardiac risks in the emergency department.

Safety and efficacy of extended versus standard interval dosing of natalizumab in multiple sclerosis patients: a systematic review and meta-analysis.

BACKGROUND: Multiple sclerosis (MS) is a chronic inflammatory, immune-mediated disease affecting the central nervous system. Natalizumab, an FDA-approved monoclonal antibody for MS, has been explored for its off-label extended interval dosing (EID), suggesting a potential reduction in the risk of progressive multifocal leukoencephalopathy (PML) compared to standard interval dosing (SID). Our objective was to assess the efficacy and safety of EID in comparison to SID for natalizumab treatment in patients with MS. METHODS: We searched PubMed, Embase, WOS, Scopus, Ovid, Science Direct, Clinical trials.gov, and Cochrane Library. Our assessed outcomes were clinical relapses, MRI activity, change in expanded disability status scale [EDSS], and the risk of PML. The EID group was defined as 5 to 8 weeks [EID (Q5-8W)]. The analysis was conducted using RevMan ver. 5.4. The effect estimates were presented as a risk ratio [RR] or mean difference with 95% confidence intervals [CI] using SID group as the reference for comparisons. RESULTS: Fourteen studies met our inclusion criteria: 2 RCTs, 1 switched single-arm trial, and 12 observational studies. No significant differences were found in all efficacy outcomes of interest. Risk of clinical relapses [RR = 0.90, (95%CI 0.80, 1.02)], risk of new or newly enlarging T2 hyperintense MRI lesions [RR = 0.78, (95%CI 0.59, 1.04)], risk gadolinium enhancing lesions [RR = 1.30, (95%CI 0.98, 1.72)], change in EDSS [MD = 0.09 (95%CI - 0.57, 0.76)], risk of PML [RR = 1.09, 95%CI (0.24, 4.94)]. CONCLUSION: In summary, our meta-analysis indicates that natalizumab maintains its effectiveness under extended interval dosing [up to 8 weeks], presenting comparable risks for clinical relapses, MRI lesions, EDSS, and PML. Caution is advised given study limitations and heterogeneity. Robust conclusions necessitate well-designed high-quality prospective studies.

Effect of moringa seed extract in chlorpyrifos-induced cerebral and ocular toxicity in mice.

Chlorpyrifos (CPF) is one of the most commonly used organophosphosphate-based (OP) insecticides. Its wide use has led to higher morbidity and mortality, especially in developing countries. Moringa seed extracts (MSE) have shown neuroprotective activity, antioxidant, anti-inflammatory, and antibacterial features. The literature lacks data investigating the role of MSE against CPF-induced cerebral and ocular toxicity in mice. Therefore, we aim to investigate this concern. A total of 40 mature male Wistar Albino mice were randomly distributed to five groups. Initially, they underwent a one-week adaptation period, followed by a one-week treatment regimen. The groups included a control group that received saline, MSE 100 mg/kg, CPF 12 mg/kg, CPF-MSE 50 mg/kg, and CPF-MSE 100 mg/kg. After the treatment phase, analyses were conducted on serum, ocular, and cerebral tissues. MSE100 and CPF-MSE100 normalized the pro-inflammatory markers (interleukin-1ß (IL-1ß), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α)) and AChE serum levels. CPF-MSE50 significantly enhanced these serum levels compared to CPF; however, it showed higher levels compared to the control. Moreover, the tissue analysis showed a significant decrease in oxidative stress (malondialdehyde (MDA) and nitric oxide (NO)) and an increase in antioxidant markers (glutathione (GSH), glutathione peroxidase (GSH-PX)), superoxide dismutase (SOD), and catalase (CAT) in the treated groups compared to CPF. Importantly, the significance of these effects was found to be dose-dependent, particularly evident in the CPF-MSE100 group. We conclude that MSE has a promising therapeutic effect in the cerebral and ocular tissues of CPF-intoxicated mice, providing a potential solution for OP public health issues.

Antioxidant, anti-inflammatory, and anti-DNA damage effects of carnosic acid against aflatoxin B1-induced hepatic, renal, and cardiac toxicities in rats.

Background: Aflatoxin B1 (AFB1) food contamination is a global health hazard that has detrimental effects on both human and animal health. The objective of the current study is to assess the protective impact of carnosic acid against AFB1-induced toxicities in the liver, kidneys, and heart. Methods: Forty male Wistar Albino rats (weighting 180 ~ 200 g) were allocated into 5 groups (8 rats each); the 1st group received saline as served as a control, the 2nd group received carnosic acid (CA100) at a dose of 100 mg/kg bw/day by gavage for 14 days, the 3rd group received AFB1 at a dose of 2.5 mg/kg bw, orally twice on days 12 and 14, the 4th group (AFB1-CA50) received AFB1 as in the 3rd group and CA at a dose of 50 mg/kg bw/day, and the 5th group (AFB1-CA100) received AFB1 as in the 3rd group and CA as in the 2nd group. Results: CA significantly decreased the liver enzymes (ALT, AST. ALP), renal function products (LDH, BUN, creatinine), and cardiac enzymes (CK and CK-MB) to control levels after the high increment by AFB1 exposure. Moreover, CA significantly decreased the oxidative stress (MDA, NO, 8-OHdG) and increased the antioxidant enzyme activities (CAT, GSH, GSH-Px, and SOD) after severe disruption of oxidant/antioxidant balance by AFB1 exposure. Interestingly, CA significantly decreased the proinflammatory mediators (IL-6, IL-1ß, and TNF-α) to the control levels after severe inflammation induced by AFB1 exposure. Conclusions: Conclusively, CA had antioxidant, anti-inflammatory, and anti-DNA damage effects against hepatic, renal, and cardiac AFB1-induced toxicities.

Knowledge, Attitude and Perceptions of Healthcare Workers in Arab Countries Regarding Basic Life Support; a Systematic Review and Meta-Analysis.

Introduction: Effective Basic Life Support (BLS) interventions, including cardiopulmonary resuscitation (CPR), are essential for enhancing survival rates. This review aimed to evaluate the knowledge, attitudes, and perceptions (KAP) of healthcare professionals regarding BLS in Arab countries. Methods: We conducted a systematic search on PubMed, Cochrane, Scopus, Web of Science, and EMBASE, to identify relevant studies. We included studies performed in Arab countries that included healthcare workers' KAP assessment towards BLS. The meta-analysis was carried out utilizing the OpenMeta Analyst Software, and a subgroup analysis was performed for Nursing staff category. The quality of the included cross-sectional studies was assessed through Newcastle-Ottawa quality assessment scale. Results: A total of 18 studies were included in our study, and eight of them entered the analysis. The study showed that 61.3% (95% confidence interval (CI): 48.9%, 73.7%, p<0.001) of health care workers were knowledgeable about the correct CPR ratio, and 62.1% (95% CI: 51.7%, 72.5%, p<0.001) answered the location of chest compression correctly. While, only 36.5% (95% CI: 23.5%, 49.6%, p<0.001) had correct answers regarding the compression rate, 48.1% (95% CI: 38.1%, 58.0%, p<0.001) were aware of the compression depth, and 34.8% (95% CI: 22.9%, 46.7%, p<0.001) answered the sequence correctly. Conclusion: The study revealed a gap regarding the BLS KAP of healthcare workers in different Arab countries, which crucially requires taking actions, in terms of frequent certified training sessions, assessments, and clear protocols.

Risk factors of diabetes and cancer-specific mortalities in patients with infiltrating ductal carcinoma of the breast: a population-based study.

BACKGROUND AND AIMS: Breast cancer is considered one of the most common neoplasms worldwide. Diabetes (DM) increases mortality among postmenopausal patients with breast cancer. Our study aims to identify the risk factors of DM-specific mortality and infiltrating ductal carcinoma (IDC) mortality in patients with IDC of the breast. MATERIALS AND METHODS: Data of IDC patients were obtained from the Surveillance, Epidemiology, and End Results database from 1975 to 2016. Independent variables included age, race, marital status, the primary site of IDC, breast subtype, the disease stage, grade, chemotherapy, radiation, and surgery. Kaplan-Meier, Cox and Binary regression tests were used to analyze the data using SPSS software. RESULTS: A total of 673 533 IDC patients were analyzed. Of them, 4224 died due to DM and 116 822 died due to IDC. Factors that increase the risk of overall, IDC-specific, and DM-specific mortalities include older age, black race, widowed, uninsured, regional and distant stages, grade II and III, and no treatment with chemotherapy or radiotherapy or surgery. Additionally, the IDC mortality increased with separated status, all primary sites, all breast subtypes, and stage IV. CONCLUSION: In patients with IDC, controlling DM besides cancer is recommended to reduce the mortality risk. Old, black, widowed, uninsured, regional and distant stages, grade II and III, and no treatment are common risk factors for DM- and IDC-mortality.

Mobile Stroke Units in Acute Ischemic Stroke: A Comprehensive Systematic Review and Meta-Analysis of 5 "T Letter" Domains.

Intravenous thrombolysis (IVT) may be administered to stroke patients requiring immediate treatment more quickly than emergency medical services if certain conditions are met. These conditions include the presence of mobile stroke units (MSUs) with on-site treatment teams and a computed tomography scanner. We compared clinical outcomes of MSU conventional therapy by emergency medical services through a systematic review and meta-analysis. We searched key electronic databases from inception till September 2021. The primary outcomes were mortality at 7 and 90 days. The secondary outcomes included the modified Rankin Scale score at 90 days, alarm to IVT or intra-arterial recanalization, and time from symptom onset or last known well to thrombolysis. We included 19 controlled trials and cohort studies to conduct our final analysis. Our comparison revealed that 90-day mortality significantly decreased in the MSU group compared with the conventional care group [risk ratio = 0.82; 95% confidence interval (CI), 0.71-0.95], while there was no significant difference at 7 days (risk ratio = 0.89; 95% CI, 0.69-1.15). MSU achieved greater functional independence (modified Rankin Scale = 0-2) at 90 days (risk ratio = 1.08; 95% CI, 1.01-1.16). MSU was associated with shorter alarm to IVT or intra-arterial recanalization time (mean difference = -29.69; 95% CI, -34.46 to -24.92), treating patients in an earlier time window, as shown through symptom onset or last known well to thrombolysis (mean difference = -36.79; 95% CI, -47.48 to -26.10). MSU-treated patients had a lower rate of 90-day mortality and better 90-day functional outcomes by earlier initiation of IVT compared with conventional care.

Demographic and treatment risk factors of cancer-specific mortality among children and adolescent leukemia patients: a population-based study.

Leukemia is the 15th most commonly diagnosed cancer and the 11th leading cause of cancer mortality. The high mortality rate of leukemia could be attributed to numerous factors. Therefore, we aimed to identify the demographic and treatment risk factors influencing mortality among patients diagnosed with leukemia. Patients' data from 1975 to 2016 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. We used the Person's chi-square test to examine the associations among the categorical variables. Kaplan-Meier and Cox regression were applied for univariate and multivariate analyses. Standardized mortality ratios were utilized to compare the mortality rates of leukemia patients and the general US population. We carried out the statistical analysis using SPSS software. A total of 18,880 patients with leukemia were studied. The leukemia incidence was increased in children than in adolescents. Acute lymphoid leukemia (ALL) was the most common type diagnosed among children and adolescents: 10,331 and 4112 patients, respectively. All mortality ratios were significantly higher in leukemia patients compared to the US population. The risk of mortality among leukemia patients was higher among adolescents, females, Black, urban areas with a 20,000 population, and patients not receiving chemotherapy. In contrast, the mortality risk was decreased in patients with higher family incomes, those not treated with radiation, and diagnosed from 2000 to 2016. In conclusion, Leukemia's incidence increases with time. Adolescents, males, Black, in some urban areas, and patients who have not received chemotherapy had the highest mortality risk among leukemia patients.

Acute aflatoxin B1-induced hepatic and cardiac oxidative damage in rats: Ameliorative effects of morin.

Aflatoxins (AFs) are secondary metabolites produced by the fungus Aspergillus flavus, of which Aflatoxin-B1 (AFB1) appears to be the most cancerogenic and of the highest toxicity. AFB1 causes serious effects on several organs including the liver. Morin is a flavonol that exists in many fruits and plants and has diverse biological properties including anticancer, anti-atherosclerotic, antioxidant, anti-inflammatory, immunomodulatory, and multi-organ protective activities. The present study aims to evaluate the potential protective effects of morin against acute AFB1-induced hepatic and cardiac toxicity in rats. Forty rats were divided into five groups (n = 8) as follows: control received the vehicle, morin was orally administered 30/mg/kg body weight (MRN30), the AFB1 was administered orally at a dose of 2.5 mg/kg, twice on days 12 and 14 of the experiment for the 3rd, 4th, and 5th groups., AFB1-MRN15 was orally given morin at a dose of 15 mg/kg body weight, and AFB1-MRN30 orally received morin at 30 mg/kg body weight. The results indicated a significant decrease in serum AST, ALP, LDH, GGT, CK, CK-MB, 8-OHdG, IL-1ß, IL-6, TNF-a levels in MRN30 compared to AFB1, and AFB1-MRN15 groups. However, the results indicated non-significant differences in the serum levels between MRN30, control, and AFB1-MRN30 groups. Meanwhile, regarding the hepatic and cardiac parameters, there were significant differences in the levels of MDA, NO, GSH, GSH-Px, SOD, and CAT in MRN30 compared to AFB1, and AFB1-MRN15 groups, overall implying the protective effects of morin. To conclude, morin at a dose of 30 mg/kg b. wt. showed significant enhancements in acute AFB1-induced hepatic and cardiac toxicity in rats, which could play a role in limiting the public health hazards of AFs.

Ethnopharmacological Study of Medicinal Plants Used in the Treatment of Skin Burns in the Arab World.

Traditional healers are often practiced in rural areas owing to cultural beliefs and are known to provide various forms of healthcare and home remedies. Patients in the Mediterranean region rely on traditional medicine to cure a variety of health concerns, like skin burns. This study was conducted to identify the various practices used by traditional healers for treating skin burns. The survey was conducted in 18 Arab countries, including Syria, Iraq, Jordan, Saudi Arabia, Egypt, United Arab Emirates, Algeria, Bahrain, Palestine, Kuwait, Oman, Qatar, Lebanon, Yemen, Tunisia, Oman, Morocco, and Sudan. Between September 2020 and July 2021, an online questionnaire was administered to 7530 participants from 12 Asian and 5 African countries. The survey was designed to gather information from common medicinal plant users and herbalists on their practices as specialists in using various herbal and medicinal plant products for diagnosis and treatment. Among the participants, 2260 had a scientific background in plant application, and the study included one phytotherapeutic professional. The crude-extraction technique was favored, by Arabic folk, for plant preparation over the maceration and decoction method. Olive oil was the most commonly used product among participants as an anti-inflammation and for scar reduction. Aloe vera, olive oil, sesame, Ceretonia siliqua, lavender, potato, cucumber, shea butter, and wheat flour are used as crude drugs to reduce pain because of their analgesic and cooling effects. The present study is the first database of medicinal plants with burn-healing properties conducted in Arab countries. These plants can be employed in the search for new bioactive substances through pharmacochemical investigations, as well as in the development of new formulations containing a combination of these plants.

Hospital and laboratory outcomes of patients with COVID-19 who received vitamin D supplementation: a systematic review and meta-analysis of randomized controlled trials.

Coronavirus disease 2019 (COVID-19) has a wide-ranging spectrum of clinical symptoms, from asymptomatic/mild to severe. Recent research indicates that, among several factors, a low vitamin D level is a modifiable risk factor for COVID-19 patients. This study aims to evaluate the effect of vitamin D on hospital and laboratory outcomes of patients with COVID-19.Five databases (PubMed, Embase, Scopus, Web of Science, and Cochrane Library) and clinicaltrials.gov were searched until July 2022, using relevant keywords/Mesh terms. Only randomized clinical trials (RCTs) that addressed the topic were included. The Cochrane tool was used to assess the studies' risk of bias, and the data were analyzed using the review manager (RevMan 5.4).We included nine RCTs with 1586 confirmed COVID-19 patients. Vitamin D group showed a significant reduction of intensive care unit (ICU) admission (risk ratio = 0.59, 95% confidence interval (CI) [0.41, 0.84], P = 0.003), and higher change in vitamin D level (standardized mean difference = 2.27, 95% CI [2.08, 2.47], P < 0.00001) compared to the control group. Other studied hospital and laboratory outcomes showed non-significant difference between vitamin D and the control group (P ≥ 0.05).In conclusion, vitamin D reduced the risk of ICU admission and showed superiority in changing vitamin D level compared to the control group. However, other outcomes showed no difference between the two groups. More RCTs are needed to confirm these results.
