RESUMEN
BACKGROUND: Cardiovascular disease (CVD) represents a significant health challenge in Egypt, yet there exists limited understanding regarding the knowledge, attitudes, and physical activity levels associated with CVD. These factors play a pivotal role in developing effective prevention and management strategies. Hence, this cross-sectional study aimed to evaluate Egyptian adults' knowledge, attitudes, and physical activity (KAP) levels. METHODS: Data were collected using a previously validated questionnaire encompassing demographic characteristics, CVD knowledge (including risk factors and symptoms), attitudes toward CVD, and self-reported physical activity levels. The survey was distributed among social media channels, and trained researchers administered the questionnaire via face-to-face interviews with adult patients with and without CVD admitted to Cairo University Hospital clinics. RESULTS: The study involved 591 participants, of whom 21.7% had CVD. Overall, participants exhibited poor knowledge regarding CVD, with a mean score of 21 ± 7 out of 40, equivalent to 52.5%. Attitudes toward CVD were moderate, with a mean score of 66.38 ± 8.7 out of 85, approximately 78%. Physical activity levels per week were also moderate, averaging 1188 MET-min with a range of 1121-18,761. Subgroup analysis revealed that individuals with CVD had lower average knowledge, attitude, and physical activity levels than those without CVD. Working in the healthcare field was a predictor of higher knowledge score (standard error (SE) 5.89, 95% confidence interval (CI) 4.61 to 7.17, P < 0.001), while those with CVD and smokers were predictors of lower attitude score (SE -4.08, 95% CI -6.43 to -1.73, P < 0.001) and (SE -2.54, 95% CI -4.69 to -0.40, P = 0.02), respectively. CONCLUSION: The study findings highlight a significant disparity in knowledge, attitudes, and physical activity levels related to CVD in Egypt. Targeted interventions aimed at improving awareness, fostering positive attitudes, and promoting physical activity among individuals at risk for CVD are crucial for effective prevention and management.

BACKGROUND: Surgery is the primary treatment for chronic subdural hematoma, and anesthesia significantly impacts the surgery's outcomes. A previous systematic review compared general anesthesia to local anesthesia in 319 patients. Our study builds upon this research, analyzing 4,367 cases to provide updated and rigorous evidence. METHODS: We systematically searched five electronic databases: PubMed, Cochrane Library, Scopus, Ovid Medline, and Web of Science, to identify eligible comparative studies. All studies published until September 2023 were included in our analysis. We compared six primary outcomes between the two groups using Review Manager Software. RESULTS: Eighteen studies involving a total of 4,367 participants were included in the meta-analysis. The analysis revealed no significant difference between the two techniques in terms of 'recurrence rate' (OR = 0.95, 95% CI [0.78 to 1.15], P = 0.59), 'mortality rate' (OR = 1.02, 95% CI [0.55 to 1.88], P = 0.96), and 'reoperation rate' (OR = 0.95, 95% CI [0.5 to 1.79], P = 0.87). Local anesthesia demonstrated superiority with a lower 'complications rate' than general anesthesia, as the latter had almost 2.4 times higher odds of experiencing complications (OR = 2.4, 95% CI [1.81 to 3.17], P < 0.00001). Additionally, local anesthesia was associated with a shorter 'length of hospital stay' (SMD = 1.19, 95% CI [1.06 to 1.32], P < 0.00001) and a reduced 'duration of surgery' (SMD = 0.94, 95% CI [0.67 to 1.2], P < 0.00001). CONCLUSION: Surgery for chronic subdural hematoma under local anesthesia results in fewer complications, a shorter length of hospital stay, and a shorter duration of the operation.

Background There are several patterns of metastatic spread from endometrial cancer (EC). Although studies have been conducted to study the EC population with distant metastasis in the bone and lungs, there is still a lack of studies on liver metastasis. This study aims to evaluate and assess the clinical features and prognostic factors of EC patients with liver metastasis. Methodology We conducted a retrospective cohort study adhering to the guidelines for reporting observational research. We utilized the Surveillance, Epidemiology, and End Results database to gather data on female patients diagnosed with EC and reported liver metastasis. We estimated survival curves using the Kaplan-Meier method and evaluated differences in survival using the log-rank test. We also conducted univariable and multivariable Cox proportional hazards regression analyses to determine the hazard ratios with 95% confidence intervals for overall survival (OS) and identify factors that impact survival. Results We analyzed data from 1,034 EC patients with liver metastasis. Median OS after liver metastasis was six months, and cancer-specific survival was seven months. Univariate Cox regression analysis revealed several factors associated with decreased OS in EC patients. These included age (≥60 years), non-endometrioid and sarcoma histological subtypes, absence of surgery, no chemotherapy, and the presence of distant metastasis to the lung, brain, and bone. Conversely, married marital status and white race were linked to a better prognosis. Subsequent multivariate Cox regression analysis identified age (≥60 years), non-endometrioid histological subtype, absence of surgery, no chemotherapy, and the presence of distant metastasis to lung, brain, and bone remaining as independent risk factors for decreased OS. In contrast, the white race still emerged as an independent prognostic factor for better OS. Conclusions Various risk factors, such as age, race, lung, bone, or brain metastasis, as well as chemotherapy and surgery, may influence the prognosis of individuals with primary EC liver metastases.
RESUMEN
BACKGROUND: Elevated circulating cholesterol levels in patients with acute coronary syndrome (ACS) increase morbidity and mortality. Recent studies reported that PCSK9 inhibitors (PCSK9i) have a beneficial effect on various domains of patients' lipid profiles and cardiovascular and mortality outcomes. Here, we aim to further investigate the efficacy and safety of PCSK9i in patients with ACS or who experienced recent episodes. METHODS: We comprehensively searched PubMed, Scopus, Web of Science and Cochrane CENTRAL to identify all randomized controlled trials comparing PCSK9i versus placebo. Data were extracted and analysed using Stata/MP version 17.0. RESULTS: Eleven studies (n = 24,732) were included in this meta-analysis. In terms of efficacy outcomes, compared with the control group, PCSK9i significantly decreased levels of LDL-C, TC, TG, Lp (a) and Apo-B, with the following values, respectively: Cohen's d of - 1.25, 95% confidence interval (CI - 1.64 to - 0.87); Cohen's d of - 1.32, 95% CI (- 1.83 to - 0.81); Cohen's d of - 0.26, 95% CI (- 0.37 to - 0.14); Cohen's d of - 0.70, 95% CI (- 1.15 to - 0.26); and Cohen's d of - 1.46, 95% CI (- 1.97 to - 0.94). The levels of HDL-C and Apo-A1 increased by: Cohen's d 0.27, 95% CI (0.16-0.39) and Cohen's d of 0.30, 95% CI (0.17-0.42), respectively. Regarding safety outcomes, PCSK9i was associated with lower odds of myocardial infarction (MI) and cerebrovascular events with the following values, respectively: OR = 0.87, 95% CI (0.78-0.97) and OR = 0.71, 95% CI (0.52-0.98). CONCLUSIONS: PCSK9i was associated with better lipid profile and quality of life of patients and can be recommended as an optimal treatment strategy. Further trials should study combinations of PCSK9i with other lipid-lowering drugs.

INTRODUCTION: The published studies comparing transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in pure aortic regurgitation (AR) are conflicting. We conducted this systematic review and meta-analysis to compare TAVI with SAVR in pure AR. METHODS: We searched PubMed, Embase, Web of Science (WOS), Scopus, and the Cochrane Library Central Register of Controlled Trials (CENTRAL) from inception until 23 June 2023. Review Manager was used for statistical analysis. The risk ratio (RR) with a 95% confidence interval (CI) was used to compare dichotomous outcomes. Continuous outcomes were compared using the mean difference (MD) and 95% CI. The inconsistency test (I2) assessed the heterogeneity. We used the Newcastle-Ottawa scale to assess the quality of included studies. We evaluated the strength of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) scale. RESULTS: We included six studies with 5633 patients in the TAVI group and 27,851 in SAVR. In-hospital mortality was comparable between TAVI and SAVR (RR = 0.89, 95% CI [0.56, 1.42], P = 0.63) (I2 = 86%, P < 0.001). TAVI was favored over SAVR regarding in-hospital stroke (RR = 0.50; 95% CI [0.39, 0.66], P < 0.001) (I2 = 11%, P = 0.34), in-hospital acute kidney injury (RR = 0.56; 95% CI: [0.41, 0.76], P < 0.001) (I2 = 91%, P < 0.001), major bleeding (RR = 0.23; 95% CI: [0.17, 0.32], P < 0.001) (I2 = 78%, P < 0.001), and shorter hospital say (MD = - 4.76 days; 95% CI: [- 5.27, - 4.25], P < 0.001) (I2 = 88%, P < 0.001). In contrast, TAVI was associated with a higher rate of pacemaker implantation (RR = 1.68; 95% CI: [1.50, 1.88], P < 0.001) (I2 = 0% P = 0.83). CONCLUSION: TAVI reduces in-hospital stroke and is associated with better safety outcomes than SAVR in patients with pure AR.

The coexistence of atrial fibrillation (AF) with heart failure (HF) is prevalent, leading to severe complications. This review aimed to investigate the success rate and efficacy of cryoballoon ablation (CBA) by measuring the improvement in the New York Heart Association (NYHA) classification and the effect on the left ventricular systolic function in patients with AF accompanied by heart failure with reduced ejection fraction (HFrEF). Electronic databases search included PubMed, Web of Science, and Scopus in January 2023. Outcomes addressed the following: left ventricular ejection fraction (LVEF) improvement, AF recurrence, NYHA classification improvement, and mortality. STATA 17.0 software was used for data analysis. The effect size for the studies was a standard mean difference (SMD) with a 95% confidence interval (CI) for outcomes. Proportion analysis with 95% CI was used for freedom from early AF and AF after 2 years and all-cause death. We included six studies, including 1699 HF patients with 365 HFrEF patients. The SMD of postoperative LVEF compared to preoperative LVEF in HFrEF was 0.99 ([95% CI: 0.60, 1.39], p = .00), and for NYHA was -1.12 ([95% CI: -1.36, -0.87], p = .00). The analysis results in HFrEF patients for freedom from AF after 1 year was 65% ([95% CI: 0.55, 0.75], and after 2 years was 39% ([95% CI: 0.10, 0.67]). Proportional analysis was conducted for all-cause death, resulting in 3% mortality ([95% CI: -0.01, 0.07]). Cryoablation of AF accompanied by HFrEF appeared safe as it reduced AF recurrence and enhanced clinical outcomes.

Certain dietary chemicals influenced the expression of chemopreventive genes through the Nrf2-Keap1 pathway. However, the difference in Nrf2 activation potency of these chemicals is not well studied. This study is aimed at determining the difference in the potency of liver Nrf2 nuclear translocation induced by the administration of equal doses of selected dietary chemicals in mice. Male ICR white mice were administered 50 mg/kg of sulforaphane, quercetin, curcumin, butylated hydroxyanisole, and indole-3-carbinol for 14 days. On day 15, the animals were sacrificed, and their livers were isolated. Liver nuclear extracts were prepared, and Nrf2 nuclear translocation was detected through Western blotting. To determine the implication of the Nrf2 nuclear translocation on the expression levels of several Nrf2-regulated genes, liver RNA was extracted for qPCR assay. Equal doses of sulforaphane, quercetin, curcumin, butylated hydroxyanisole, and indole-3-carbinol significantly induced the nuclear translocation of Nrf2 with different intensities and subsequently increased the expression of Nrf2-regulated genes with an almost similar pattern as the Nrf2 nuclear translocation intensities (sulforaphane > butylated hydroxyanisole = indole-3-carbinol > curcumin > quercetin). In conclusion, sulforaphane is the most potent dietary chemical that induces the Nrf2 translocation into the nuclear fraction in the mouse liver.

BACKGROUND: Prostate cancer (PC) is responsible for large numbers of cancer-related deaths in males worldwide, and it has been linked to an increase in cardiovascular morbidity and mortality (CVM). The purpose of this research is to identify the incidence and risk factors for CVM in PC patients. METHODS: In this retrospective cohort study, we collected data from patients with PC diagnosed between 2000 and 2014 from the Surveillance, Epidemiology, and End Results (SEER) database. CVM among PC patients was identified and compared to the general population using the standardized mortality ratio (SMR). The multivariable competing risk model with subdistribution hazard ratio (SHR) was used to analyze the data in a more complex method to discover the risk factors associated with CVM among PC patients. RESULTS: Of the 171,147 identified PC patients, the median survival time was 117 months, with 17,168 dying from cardiovascular disease (CVD). Patients diagnosed at age 45-54 had a higher CVM risk than the age-standardized general population (SMR (95% CI): 19.01 (17.17-21.0)). Using multivariate competing risk regression analysis, aged 85 and older (SHR (95% CI): 20.9 (18.628-23.467)), black ethnicities (SHR (95% CI): 1.3 (1.264-1.398)), and patients without surgical intervention (SHR (95% CI): 1.35 (1.305-1.410)) had higher CVM. On the other hand, being of Asian/Pacific Islander or American Indian/Native Alaskan ethnicity (SHR (95% CI): 0.94 (0.891-0.993)), being diagnosed between 2007 and 2014 (SHR (95% CI): 0.63 (0.613-0.655)), and having an advanced disease stage and a lack of disease differentiation in the histology were found to be related with a lower CVM. CONCLUSION: Patients with PC have a greater likelihood of dying from CVD. Several important risk factors for CVD have been discovered, including advanced age, black ethnicity, and patients without surgical intervention. These findings are limited by the retrospective nature of the analysis, relying solely on the SEER database, which imposes restrictions on accessing comprehensive patient data, including lifestyle factors and medical history.
RESUMEN
BACKGROUND: The concept of pharmacovigilance is not well known in Libya and its practice is still in the early stages. AIMS: This study aimed to determine the knowledge, attitudes and practices of pharmacists in Tripoli, Libya about pharmacovigilance and the reporting of adverse drug reactions. METHODS: A cross-sectional study was conducted from October 2019 to February 2020 of working pharmacists randomly selected from pharmacies in Tripoli. Participants were eligible for inclusion if they had a degree or diploma in pharmacy from a recognized university or institute. Data were collected using a validated self-administered questionnaire. RESULTS: Of 500 pharmacists selected, 408 completed the questionnaire. The pharmacists' knowledge of pharmacovigilance and reporting of adverse drug reactions was poor overall: only 28.9% correctly defined pharmacovigilance and 14.7% knew about the existence of a centre for pharmacovigilance in Libya. The attitudes of the pharmacists to pharmacovigilance was positive: 77.2% believed that pharmacovigilance needed to be included in the pharmacy curriculum and 73.0% said that they would practice pharmacovigilance if trained. Pharmacists depended mostly on drug information leaflets to update their knowledge on adverse drug reactions. CONCLUSION: Given the pharmacists' low level of knowledge about pharmacovigilance but their readiness to become involved if trained, training programmes should be introduced for practising pharmacists to improve their knowledge and encourage their active participation in pharmacovigilance. Regulators need to reinforce the importance of reporting adverse drug reactions and implement pharmacovigilance policies in the Libyan health care system.

Introduction: The global burden of bacterial skin infection is substantial. We aimed to determine the common pathogens causes skin infections and their antimicrobial resistance pattern. Methods: A retrospective record review of data claimed from the microbiology department at Ber-Ustta Milad skin hospital between Jan 2009 to December 2018 was conducted. The consequence of interest was the antimicrobial sensitivity of bacterial isolates. Chi square was used for statistical analysis. Results: Out of 1,141 collected samples, a total of 455 isolates of different medically-significant bacteria were analyzed. The most common pathogen was S. aureus (97.14%), followed by E. coli (93.71%), and the least common was Shigella (0.57%). From the various inoculated samples, S. aureus and Proteus were highly resistant to penicillin (34.3%, 75% respectively) and ampicillin (28.6%, 62.5% respectively). E. coli was highly resistant to ampicillin (45.12%) and penicillin (35.96%), whereas the lowest resistant was against imipenem (3.05%). While, Pseudomonas was highly resistant to ampicillin and augmentin (62.5%), whereas the lowest resistance rate was marked to erythromycin, sulfamethoxazole and imipenem (25%). Ciprofloxacin, gentamicin and nalidixic acid were the only sensitive agents. Conclusions: There is a high burden of bacterial resistance to common antibiotics in our population samples. Recognition of the potential resistant strains of pathogen causing skin infection can help in guiding proper choice of antibiotic therapy (AU)

BACKGROUND: The most common preparation of tocotrienols is the Tocotrienol-Rich Fraction (TRF). This study aimed to investigate whether TRF induced liver Nrf2 nuclear translocation and influenced the expression of Nrf2-regulated genes. METHODS: In the Nrf2 induction study, mice were divided into control, 2000 mg/kg TRF and diethyl maleate treated groups. After acute treatment, mice were sacrificed at specific time points. Liver nuclear extracts were prepared and Nrf2 nuclear translocation was detected through Western blotting. To determine the effect of increasing doses of TRF on the extent of liver nuclear Nrf2 translocation and its implication on the expression levels of several Nrf2-regulated genes, mice were divided into 5 groups (control, 200, 500 and 1000 mg/kg TRF, and butylated hydroxyanisole-treated groups). After 14 days, mice were sacrificed and liver RNA was extracted for qPCR assay. RESULTS: 2000 mg/kg TRF administration initiated Nrf2 nuclear translocation within 30 min, reached a maximum level of around 1 h and dropped to half-maximal levels by 24 h. Incremental doses of TRF resulted in dose-dependent increases in liver Nrf2 nuclear levels, along with concomitant dosedependent increases in the expressions of Nrf2-regulated genes. CONCLUSION: TRF activated the liver Nrf2 pathway resulting in increased expression of Nrf2-regulated cytoprotective genes.

BACKGROUND: Adherence to pharmacy practice guidelines for dispensing medications in pharmacy settings is important to ensure the safe use of medications. AIMS: This study assessed the pattern and adequacy of information given to consumers on over-the-counter medications dispensed in community pharmacies in Tripoli, Libya, and compared the performance of pharmacists and non-pharmacists. METHODS: This was a cross-sectional survey of private community pharmacies conducted in 2018 . Trained simulated patients were used to collect data on over-the-counter medications dispensed for hypothetical common cold symptoms and the information given by the pharmacy staff on the medication. This information included: name and the strength of the medication, indication for use, duration of use, dosage, how often to take the medicine, timing (before/after/with food), storage, expiry date, and side-effects of the medicine. Time taken to deliver the information was recorded. The adequacy of information provided by the pharmacists and non-pharmacists was compared. RESULTS: A total of 169 pharmacies were surveyed. There were no significant differences between pharmacists and non-pharmacists in information given on the dispensed medications, except for information on taking the medication with food or not (84.5% of pharmacists gave this information versus 57.1% of non-pharmacists; P = 0.001) and on potential side-effects (39.4% of pharmacists versus 20.3% of non-pharmacists; P = 0.014). Significantly more pharmacists (85.9%) than non-pharmacists (61.2%) provided the medication-related information in less than 1 minute (P = 0.001). CONCLUSION: The inadequate information on medications provided by pharmacists is a concern for patient safety. Health regulatory organizations need to promote safe medication practices.

PURPOSE: To evaluate the problems and accuracy of biometry in eyes that have been operated on by silicone oil removal combined with cataract extraction with or without intraocular lens implantation. SUBJECTS AND METHODS: Twenty-nine consecutive cases that have been operated on for silicone oil removal and cataract, with or without intraocular lens implantation, were included in a prospective study. Axial length measurement was done in silicone oil-filled eyes after changing the sound speed in vitreous cavity to 987 m/sec. The SRKT formula was used for intraocular lens calculation. The cataract was removed by phacoemulsification through corneal section or phacofragmentation through the standard vitrectomy sclerotomy. Intraocular lens implantation was done either on the peripheral anterior capsule (single piece, PMMA) or in the bag (acrylic foldable three pieces). The final refraction after at least 3 months' follow-up was measured. The difference between the predicted and the actual refraction was evaluated. A control group of 30 consecutive cases (20 nonmyopic and 10 highly myopic) of cataract extraction and intraocular lens implantation in eyes not filled with silicone oil was included using the same evaluation methods. RESULTS: The mean deviation of the final from the predicted refraction was 1.87 +/- 2.11 diopters (range, +3.25 to -9 diopters). A total of 72.4% had a deviation of +/-2 diopters. The mean deviation in high myopia was 3.04 +/- 2.68 diopters (12 cases) (range, +/-1.75 to -9 diopters), while in nonmyopic patients, the mean deviation was 1.04 +/- 1.04 diopters (17 cases) (range, +3.25 to -3.25 diopters). The difference between highly myopic and nonmyopic eyes was statistically significant (P < 0.05). Most high errors occurred in highly myopic eyes. There was no statistical difference between the types of silicone oil (1000 versus 5000) or the mode of cataract extraction (phacoemulsification versus pars plana phacofragmentation). In the control group, the mean deviation in high myopia was 1.48 +/- 1.02 diopters (10 cases) (range, +/-0.5 to -3.5 diopters), while in nonmyopic patients, the mean deviation was 0.65 +/- 0.75 diopters (20 cases) (range, +2.75 to -1.75 diopters). The difference was statistically significant (P < 0.05). CONCLUSION: Intraocular lens calculation in silicone oil-filled eyes is accurate in eyes that are not highly myopic. Some highly myopic eyes with posterior staphyloma have great deviation. Unsuitable formula, artifacts, or large eyes beyond the machine range may be the cause of errors of deviation of refraction. Comparable results are obtained in eyes regardless of the type of silicone oil (1000 or 5000) and techniques of intraocular lens implantation (in the sulcus or in the bag).
