The Effect of a Vegan Diet on the Health Indicators and Outcomes of P atients with Type 2 Diabetes Mellitus.

INTRODUCTION/OBJECTIVES: Recently, there has been a notable increase in interest in various forms of vegetarianism, which may be due to the growing prevalence of health issues, such as Type 2 Diabetes Mellitus (T2DM). Adhering to a vegan diet may have positive health outcomes. As a result, we conducted a review article to gather data from previous research studies on the effects of a vegan diet on different aspects of managing patients with T2DM. METHODS: We searched the PubMed website for research studies on how a vegan diet affects the outcomes of patients with T2DM. The research studies were categorized according to the type of data collected, such as prevalence, incidence, body weight, insulin resistance, glycemic control, and lipid profile. RESULTS: It was found that following a vegetarian diet can significantly reduce the risk of mortality from heart disease. Additionally, studies have demonstrated that a vegetarian diet is linked to several improvements in T2DM. However, long-term weight loss plans and managing T2DM is a comprehensive intervention that includes caloric restriction, exercise, and behavioral modification. CONCLUSION: Incorporating a vegan diet can be a valuable factor to consider in managing T2DM, as it can offer numerous benefits, such as increased insulin sensitivity, weight loss, and reduced blood sugar levels. It helps to reduce cholesterol levels, LDL, and triglyceride levels, which are all risk factors associated with T2DM. By reducing these risk factors, the vegan diet can improve the overall health of T2DM patients.

Assessing satisfaction, quality of life, and HbA1c changes in type 1 diabetes patients who are using freestyle libre glucose monitoring.

Introduction: Type 1 diabetes mellitus (T1DM) is a chronic auto-immune disease in which loss of pancreatic islet ß-cells leads to the deficiency of insulin in the body thus resulting in enhanced blood sugar levels. Effective blood glucose monitoring is crucial in T1DM management to prevent complications, particularly hypoglycemia. Method: The study adopted a cross-sectional survey to assess satisfaction and quality of life among T1DM patients using the freestyle libre continuous glucose monitoring (FSL-CGM), and a retrospective cohort study design to evaluate changes in HbA1c over a year. Result: The study involved 98 Saudi subjects, with 46.9% (n = 46) being male. The results indicated a high level of user satisfaction, with more than 85% of the participants responding positively, yielding a total satisfaction score of 30.86. User satisfaction with FSL-CGM was found to be significantly associated with the level of education. The use of FSL-CGM was also found to significantly improve the patients' quality of life. However, the levels of HbA1c had an impact on both satisfaction and quality of life. Before using the FSL-CGM system, the mean HbA1c was 9.83%, which significantly decreased to 8.63% after using the system (P-value <0.001). Conclusion: The study's findings align with previous literature on satisfaction and quality of life, but there are conflicting results regarding the reduction of HbA1c levels using FSL-CGM. Given the limited sample size, future research could explore the topic more comprehensively, potentially utilizing a longitudinal study design to better measure changes in HbA1c level.

From proteome to candidate vaccines: target discovery and molecular dynamics-guided multi-epitope vaccine engineering against kissing bug.

Introduction: Trypanosoma cruzi is a protozoan parasite that causes the tropical ailment known as Chagas disease, which has its origins in South America. Globally, it has a major impact on health and is transported by insect vector that serves as a parasite. Given the scarcity of vaccines and the limited treatment choices, we conducted a comprehensive investigation of core proteomics to explore a potential reverse vaccine candidate with high antigenicity. Methods: To identify the immunodominant epitopes, T. cruzi core proteomics was initially explored. Consequently, the vaccine sequence was engineered to possess characteristics of non-allergenicity, antigenicity, immunogenicity, and enhanced solubility. After modeling the tertiary structure of the human TLR4 receptor, the binding affinities were assessed employing molecular docking and molecular dynamics simulations (MDS). Results: Docking of the final vaccine design with TLR4 receptors revealed substantial hydrogen bond interactions. A server-based methodology for immunological simulation was developed to forecast the effectiveness against antibodies (IgM + IgG) and interferons (IFN-g). The MDS analysis revealed notable levels of structural compactness and binding stability with average RMSD of 5.03 Aring;, beta-factor 1.09e+5 Å, Rg is 44.7 Aring; and RMSF of 49.50 Aring;. This is followed by binding free energies calculation. The system stability was compromised by the complexes, as evidenced by their corresponding Gibbs free energies of -54.6 kcal/mol. Discussion: Subtractive proteomics approach was applied to determine the antigenic regions of the T cruzi. Our study utilized computational techniques to identify B- and T-cell epitopes in the T. cruzi core proteome. In current study the developed vaccine candidate exhibits immunodominant features. Our findings suggest that formulating a vaccine targeting the causative agent of Chagas disease should be the initial step in its development.

Prevalence and predictors of mitral annular disjunction and ventricular ectopy in mitral valve prolapse.

BACKGROUND: Mitral annular disjunction (MAD) is associated with ventricular arrhythmia in mitral valve prolapse (MVP). The proportional risk from MAD and other predictors of ventricular arrhythmia in MVP has not been well characterized. OBJECTIVE: This study aimed to identify predictors of complex or frequent ventricular ectopy (cfVE) in MVP and to quantify risk of cfVE and mortality in MVP with MAD. METHODS: We studied 632 adult patients with MVP on transthoracic echocardiography at the University of North Carolina Medical Center from 2016 to 2019 (median age, 64 [interquartile range, 52-74] years; 52.7% female; 16.3% African American). Resting and ambulatory electrocardiograms were used to identify cfVE. RESULTS: MAD was present in 94 (14.9%) patients. Independent associations of MAD were bileaflet prolapse (odds ratio [95% CI], 4.25 [2.47-7.33]; P < .0001), myxomatous valve (2.17 [1.27-3.71]; P = .005), absence of hypertension (2.00 [1.21-3.32]; P = .007), electrocardiogram inferior or lateral lead T-wave inversion (2.07 [1.23-3.48]; P = .006), and female sex (1.99 [1.21-3.25]; P = .006). cfVE was frequent with MAD (39 [41.5%] vs 93 [17.3%] without; P < .0001). Independent cfVE predictors were MAD (hazard ratio [95% CI], 2.23 [1.47-3.36]; P = .0001), bileaflet prolapse (1.86 [1.25-2.76]; P = .002), heart failure (1.79 [1.16-2.77]; P = .009), lower left ventricular ejection fraction (0.14 [0.03-0.61]; P = .009), coronary artery disease (1.60 [1.05-2.43]; P = .03), and inferior or lateral lead T-wave inversion (1.51 [1.03-2.22]; P = .03). After a median of 40 (33-48) months, there was increased mortality with MAD (P = .04). CONCLUSION: MAD in MVP is associated with bileaflet or myxomatous MVP, absence of hypertension, T-wave inversion, and female sex. There is increased cfVE and mortality with MAD, highlighting the need for closer follow-up of these patients.

Clinical Presentations and Risk Factors of Gastrointestinal Bleeding in the Emergency Department: A Multicenter Retrospective Study.

BACKGROUND AND AIMS: Gastrointestinal bleeding is a major healthcare burden and is associated with significant morbidity and mortality. This study aimed to assess the prevalence, clinical presentation, and risk factors of patients presenting with gastrointestinal bleeding in the emergency department. MATERIALS AND METHODS: This retrospective study was conducted in two tertiary care hospitals in Riyadh, Saudi Arabia. The medical records of patients who presented to the emergency department with gastrointestinal bleeding between January 2010 and January 2020 were reviewed. Patients aged 18 years or older, with gastrointestinal bleeding (upper or lower) regardless of underlying cause, lifestyle, location of bleeding, health status, or medication use, were included. Demographic characteristics, initial vital signs, medical history, physical examination findings, comorbidities, medications, laboratory and radiological investigations, cause and stage of liver disease, management, and complications were recorded. Endoscopic findings and management of the bleeding site were collected according to the presenting symptoms. RESULTS: A total of 760 patients were included. The mean age was 62.7 ± 17.8 years, and 61.4% were males. The most common comorbidities at presentation were hypertension (54.1%), diabetes mellitus (51.2%), and ischemic heart disease (18.2%). The origins of the bleeding were lower gastrointestinal in 52% and upper gastrointestinal in 48% of patients. CONCLUSIONS: Lower gastrointestinal bleeding was found to be more common than upper gastrointestinal bleeding. Hemorrhoids, polyps, diverticular disease, and colonic ulcers were the major risk factors for lower gastrointestinal bleeding. In contrast, upper gastrointestinal bleeding was predominantly caused by esophageal varices, gastritis, and peptic ulcers.

The utility of serum glucose potassium ratio as a predictive factor for haemorrhagic transformation, stroke recurrence, and mortality among ischemic stroke patients.

Background and Objective: Glucose-Potassium Ratio (GPR) has emerged as a biomarker in several pathophysiological conditions. However, the association between GPR and long-term outcomes in stroke patients has not been investigated. Our study evaluated the applicability of baseline GPR as a predictive prognostic tool for clinical outcomes in ischemic stroke patients. Methods: The multicenter retrospective cohort study included acute-subacute adult ischemic stroke patients who had their baseline serum GPR levels measured. Eligible patients were categorized into two sub-cohorts based on the baseline GPR levels (<1.67 vs. ≥ 1.67). The primary outcome was the incidence of 30-day hemorrhagic transformation, while stroke recurrence, and all-cause mortality within twelve months, were considered secondary. Results: Among 4083 patients screened, 1047 were included in the current study. In comparison with GPR < 1.67 group, patients with ≥ 1.67 GPR had a significantly higher ratio of all-cause mortality within twelve months (aHR 2.07 [95 % CI 1.21-3.75] p = 0.01), and higher ratio of 30-day hemorrhagic transformation but failed to reach the statistical significance (aHR 1.60 [95 % CI 0.95-2.79], p = 0.08). Conclusion: Overall, baseline GPR serum is an independent predictor of all-cause mortality within twelve months in patients with acute and subacute ischemic stroke. Further clinical studies are necessary to validate these findings.

Levels of Awareness Regarding Pediatric Eye Diseases Among Saudi Parents From the Hail and Al-Qassim Regions, Saudi Arabia.

BACKGROUND: The importance of children's eye health cannot be overstated as it has significant implications for personal life, education, career, health, financial status, and overall satisfaction. This study aims to assess the awareness of parents regarding pediatric eye diseases to identify potential gaps in knowledge. By understanding parental awareness, we can develop targeted educational initiatives to promote early detection, timely intervention, and overall improved eye health in children. This research seeks to contribute valuable insights for enhancing preventive measures and fostering healthier eyesight in younger generations. METHODOLOGY:  A descriptive cross-sectional study was conducted in the Hail and Al-Qassim regions, of Saudi Arabia. Parents with children aged less than 15 years were included. Targeted parents were selected consecutively using an online questionnaire for data collection. Data included parents' data, children's eye diseases, and parents' knowledge, practice, and attitude toward pediatric eye diseases.  Results: A total of 618 eligible parents were included, 429 (69.4%) from Al-Qassim and 189 (30.6%) from Hail. Parents' ages ranged from 20 to 59 years with a mean age of 35.4 ± 11.5 years. A total of 510 (82.5%) respondents were females. A total of 442 (71.5%) of the study parents had poor knowledge about their pediatric eye problems, 154 (24.9%) had a good knowledge level, and only 22 (3.6%) had excellent knowledge. As for their practice, 458 (74.1%) of the parents arranged for their children to undergo an eye or visual test; 254 (55.5%) did so when the child was six to ten years of age. CONCLUSION:  The current study showed poor awareness levels about pediatric eye diseases among parents, mainly regarding cataracts and glaucoma. On the other hand, parents demonstrated a high level of engagement in visually assessing their children. The primary hindrance to conducting assessments was the absence of symptoms and signs or active complaints, leading to a lack of proactive seeking of visual evaluations.

Scores predicting atrial fibrillation after mitral valve surgery: Do we need a more specific score?

Background: Atrial fibrillation after cardiac surgery (POAF) is associated with increased morbidity and mortality. Several scores were used to predict POAF, with variable results. Thus, this study assessed the performance of several scoring systems to predict POAF after mitral valve surgery. Additionally, we identified the risk factors for POAF in those patients. Methods: This retrospective cohort included 1381 recruited from 2009 to 2021. The patients underwent mitral valve surgery, and POAF occurred in 233 (16.87%) patients. The performance of CHADS2, CHA2DS2-VASc, POAF, EuroSCORE II, and HATCH scores was evaluated. Results: The median age was higher in patients who developed POAF (60 vs. 54 years; p < .001). CHA2-DS2-VASc, POAF, EuroSCORE II, and HATCH scores significantly predicted POAF, with areas under the curve of the receiver operator curve (AUCROC) of 0.56, 0.61, 0.58, and 0.54, respectively. We identified age > 58 years, body mass index > 28 kg/m2, creatinine clearance < 90 mL/min, reoperative surgery, and preoperative inotropic and intra-aortic balloon pump use as predictors of POAF. We constructed a score from these variables (PSCC-AF). A score > 2 significantly predicted POAF (p < .001). The AUCROC of this score was 0.67, which was significantly higher than the AUCROC of the POAF score (p = .009). Conclusion: POAF after mitral valve surgery can be predicted based on preoperative patient characteristics. The new PSCC-AF score significantly predicted POAF after mitral valve surgery and can serve as a bedside diagnostic tool for POAF risk screening. Further studies are needed to validate the PSCC-AF-mitral score externally.

Phacoemulsification versus Laser Peripheral Iridotomy for Treating Primary Angle Closure Glaucoma: A Systematic Review and Meta-Analysis.

Background: Primary Angle Closure Glaucoma (PACG), is caused by narrowing the iridocorneal angle and increases the risk of blockage in the trabecular meshwork. Phacoemulsification and laser peripheral iridotomy (LPI) effectively control IOP elevation and widen the angle. This systematic review and meta-analysis compared Phacoemulsification and LPI Effectiveness for PACG. Methods: We searched Medline, Embase, and CENTRAL. We included randomized controlled trials (RCTs) that compared Phacoemulsification and LPI for individuals with PACG. We sought to evaluate the following outcomes: mean IOP, number of glaucoma medications, visual acuity (VA), visual field (VF) progression, peripheral anterior synechiae (PAS), Shaffer gonioscopy grading, central corneal thickness (CCT), central endothelial cell density (CECD), and poor response to surgery. The standardized mean difference (SMD) was used to represent continuous outcomes, while the risk ratio (RR) was used to represent dichotomous outcomes. Results: 5 RCTs that enrolled 917 participants were deemed eligible. The phacoemulsification group showed statistically significance lower mean CCT and CECD and lower risk of poor response to surgery compared to LPI (SMD = -1.10; 95% -1.50, -0.70; P<0.001, SMD -366.12; 95% -652.59, -79.65; P=0.01, and RR 0.35; 95% 0.23, 0.54; P<0.001 respectively). There were no significant improvement in IOP and number of medications between both groups (SMD = -0.74; 95% CI = -2.26, 0.78; P=0.34, and SMD -17.58; 95% CI = -50.28, 15.12; P=0.29 respectively). Finally, there were also no significant differences in VA, VF progression, PAS, and mean Shaffer gonioscopy grading between both groups. Conclusion: Phacoemulsification showed statistically significant lower mean corneal thickness, central endothelial cell density, and lower risk of poor response to surgery compared to LPI. However, there were no significant differences in mean IOP, number of medications, VA, VF progression, PAS, and mean Shaffer gonioscopy grading between Phacoemulsification and LPI.

Total Cystectomy in the Management of Primary Retroperitoneal Echinococcal Cysts: Current Evidence and Future Directions.

Echinococcal cysts (ECs) are a significant public health concern globally, particularly in endemic regions. Among these, primary retroperitoneal echinococcal cysts (PRECs) present unique challenges due to their location and complex presentations. Total cystectomy, involving complete removal of the EC and surrounding tissue, is a surgical option for managing PRECs. However, evidence regarding its efficacy and safety is limited. We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to evaluate the role of total cystectomy in managing PRECs. A comprehensive search of databases yielded four relevant studies. These studies reported favorable outcomes following total cystectomy, including low recurrence rates and minimal postoperative complications. However, challenges such as technical complexity and proximity to vital structures were noted. Future research should focus on evaluating minimally invasive approaches, exploring adjuvant therapies, identifying predictors of recurrence, and assessing cost-effectiveness. This systematic review underscores the need for further investigation to optimize the management of PRECs and improve patient outcomes.

Prevalence of periodontitis in Saudi Arabia: A systematic review and meta-analysis.

Objective: The aim of this systematic review was to assess the prevalence of periodontal disease among Saudi Arabian adults based on studies conducted from 1992 to 2023. Methods: The study protocol was registered in PROSPERO. Three databases (MEDLINE, EMBASE and Cochrane library) and the Saudi Dental Journal were searched for published literature up to June 2023 using prespecified search strategy. Quality of included studies was checked using the risk of bias in population-based prevalence studies tool. Results: The systematic review included 15 studies that assessed the prevalence of periodontal disease in Saudi Arabia. Most of the studies used non-confident case definitions. The pooled estimate of periodontal disease prevalence in Saudi Arabia based on the data of 14 which included 6,596 individuals is 51% (95% CI: 35.99, 73.05). Conclusion: Periodontal disease is a significant public health issue in Saudi Arabia, with a substantial prevalence among the included participants. Nevertheless, the existing studies exhibit methodological disparities and regional limitations. Therefore, while the results shed light on the pressing nature of periodontal disease in Saudi Arabia, further comprehensive research is imperative. A more accurate estimate, coupled with effective strategies, can be achieved through broader, multidisciplinary collaborations and the prioritization of a national oral health survey in Saudi Arabia.

Uncommon Complication Post-deep Sclerectomy: Giant Retinal Tear.

Glaucoma is a prevalent neurodegenerative disease. It causes progressive visual loss and is one of the most common causes of blindness worldwide. It can be categorized into open-angle or closed-angle glaucoma. Primary congenital glaucoma (PCG) is a subdivision of open-angle glaucoma. Non-penetrating deep sclerectomy (NPDS) is a surgical method for managing open-angle and primary congenital glaucoma, which was first introduced in 1990. During NPDS, a sclera flap is raised but not completely removed, and the outer part of Schlemm's canal and trabecular meshwork, along with the juxtacanalicular tissue, are excised without completely penetrating the eye. Therefore, it is considered a safe and efficient option for controlling intraocular pressure. This report shows a unique case of uncommon complication post-deep sclerectomy, a giant retinal tear, after undergoing non-penetrating deep sclerectomy for primary congenital glaucoma.

Navigating the Surgical Landscape: A Comprehensive Analysis of Endoscopic vs. Microscopic Transsphenoidal Pituitary Surgery Outcomes.

Pituitary surgery, a critical intervention for various pituitary disorders, has sparked ongoing debates regarding the preference between endoscopic and microscopic transsphenoidal approaches. This systematic review delves into the outcomes associated with these techniques, taking into account the recent advancements in neurosurgery. The minimally invasive nature of endoscopy, providing improved visualization and reduced morbidity, stands in contrast to the well-established track record of the conventional microscopic method. Examining outcomes for disorders such as Cushing's disease and acromegaly, the review synthesizes evidence from Denmark, Bulgaria, and China. Noteworthy advantages of endoscopy encompass higher resection rates, shorter surgery durations, and fewer complications, endorsing its effectiveness in pituitary surgery. While emphasizing the necessity for prospective trials, the review concludes that endoscopic approaches consistently showcase favorable outcomes, influencing the ongoing discourse on the optimal surgical strategies for pituitary disorders.

Emerging Horizons in the Diagnosis of Pancreatic Cancer: The Role of Circulating microRNAs as Early Detection Biomarkers for Pancreatic Ductal Adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive cancer with a poor prognosis, primarily due to a late diagnosis. Recent studies have focused on identifying non-invasive biomarkers for early detection, with microRNAs (miRNAs) emerging as promising candidates. This systematic review aims to evaluate the potential of circulating miRNAs as biomarkers for the early detection of PDAC, analyzing their diagnostic accuracy, specificity, and sensitivity. Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a comprehensive search across PubMed, Embase, and the Cochrane Library was conducted. Studies published from January 2013 to October 2023 focusing on miRNA biomarkers for early PDAC detection were included. Data synthesis was performed through a narrative approach due to the heterogeneity of the studies. Nine studies met the inclusion criteria. Key findings include the elevated levels of specific miRNAs, such as miR-18a, miR-106a, and miR-25, in early-stage PDAC patients compared to controls. The integration of miRNA profiles with traditional biomarkers like CA19-9 showed improved diagnostic performance. However, challenges in the standardization of miRNA evaluation methodologies were noted. Circulating miRNAs demonstrate significant potential as non-invasive biomarkers for early PDAC detection. Despite promising results, further research and standardization are necessary for clinical application.

Knowledge, Attitude, and Practice Regarding Vision and Eye Screening of Preschool Children Among Primary Health Center Staff in the Qassim Region, Saudi Arabia.

Purpose To study the knowledge, attitude, and practice (KAP) regarding vision and eye screening of preschool children among primary health center (PHC) staff in Qassim, Saudi Arabia.  Methods A survey of PHC staff was conducted in 2023. The questionnaire included knowledge (10), attitude (five), and practice (five)-related questions associated with preschool vision and eye screening. A five-graded Likert scale was used for responses. Cronbach's alpha score of the questionnaire was 0.776. The KAP score was correlated with the demographic variables of participants. The current and desired sources of information were also collected.  Results We surveyed 101 health staff (66 doctors and 35 nurses). The median (interquartile range) knowledge, attitude, and practice scores of participants were 4.1 (3.8; 4.3), 4.2 (4.0; 4.6), and 3.6 (3.0; 4.0), respectively. The doctors had better knowledge (Mann-Whitney U test (MW), P = 0.016) and attitude (MW, P = 0.019) than the nurses. Staff above 40 years had better knowledge (Kruskal-Wallis H test (KW), P = 0.035), attitude (KW, P = 0.017), and practice (KW, P < 0.001). The primary source of information about preschool vision screening was their medical education (51%). Other sources were eye care professionals (11.9%), Google and computers (12.9%), and social media (14.9%). Their preferred sources of information were medical journals (25.7%), eyecare training (22.8%), and eye professionals (33.7%). Conclusions Knowledge and attitude for eye and vision screening of preschool children was high, but practices were less among PHC staff. Providing information through their preferred mode could further strengthen eye care for preschool children.

Targeting inflammation and oxidative stress for protection against ischemic brain injury in rats using cupressuflavone.

Inflammatory responses and oxidative stress contribute to the pathogenesis of brain ischemia/reperfusion (IR) injury. Naturally occurring bioflavonoids possess antioxidant and anti-inflammatory properties. The phytochemicals of Juniperus sabina L., known as "Abhal" in Saudi Arabia, have been studied and cupressuflavone (CUP) has been isolated as the major bioflavonoid. This study aimed to investigate the neuroprotective potential of CUP in reducing brain IR damage in rats and to understand probable mechanisms. After 60 min of inducing cerebral ischemia by closing the left common carotid artery (CCA), blood flow was restored to allow reperfusion. The same surgical procedure was performed on sham-operated control rats, excluding cerebral IR. CUP or vehicle was given orally to rats for 3 days prior to ischemia induction and for a further 3 days following reperfusion. Based on the findings of this study, compared to the IR control group, CUP-administered group demonstrated reduced neurological deficits, improved motor coordination, balance, and locomotor activity. Additionally, brain homogenates of IR rats showed a decrease in malondialdehyde (MDA) level, an increase in reduced glutathione (GSH) content, and an increase in catalase (CAT) enzyme activity following CUP treatment. CUP suppressed neuro-inflammation via reducing serum inflammatory cytokine levels, particularly those of tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and interleukin-1 beta (IL-1ß) and enhancing the inflammatory cytokine levels, such as Nuclear factor kappa- B (NF-κB), TANK-binding kinase-1 (TBK1), and interferon beta (IFN-ß) in brain tissues. Furthermore, CUP ameliorated the histological alterations in the brain tissues of IR rats. CUP significantly suppressed caspase-3 expression and downregulated the Toll-like receptor 4 (TLR4)/NF-κB signaling pathway as a result of suppressing High mobility group box 1 (HMGB1). To our knowledge, this is the first study to document the neuroprotective properties of CUP. Thus, the study findings revealed that CUP ameliorates IR-induced cerebral injury possibly by enhancing brain antioxidant contents, reducing serum inflammatory cytokine levels, potentiating the brain contents of TBK1 and IFN-ß and suppressing the HMGB1/TLR-4 signaling pathway. Hence, CUP may serve as a potential preventive and therapeutic alternative for cerebral stroke.

A phenanthroline-based erbium (III) complex: molecular docking, DNA/BSA -binding and biological evaluation.

With the help of both theoretical as well as experimental research, in vitro binding research with CT-DNA (calf thymus) and BSA (bovine serum albumin) were carefully examined to figure out the chemotherapeutic and pharmacokinetic facets of the Erbium complex, which contains 1,10-phenanthroline (Phen). The binding characteristics and the mechanism of complex's interaction with DNA as well as the protein were determined utilizing fluorescence quenching method. Findings indicated that the complex's interaction with DNA via groove binding into DNA's minor grooves, with their binding constants falling within the 104 M-1 range. Furthermore, thermodynamic characteristics and the fluorescence emission of the tryptophan residues of the protein were obtained through fluorescence quenching studies at different temperatures. According to the results of the binding constants, the protein's interactions with the Er- complex were moderate, demonstrating that the compound may be transported effectively by the protein. Molecular docking results supported that of the experimental research. The HeLa and MCF-7 cancer cell lines, along with the normal human fibroblast cell line, were used in an MTT assay evaluation of the Er-complex cytotoxicity. The Er-complex displayed a selective inhibitory effect on the proliferation of different cancer cells.Communicated by Ramaswamy H. Sarma.

Assessment of prevalence of sunscreen use and related practices among people living in Saudi Arabia: A cross-sectional survey-based study.

BACKGROUND: The use of sunscreen significantly reduces the risk of skin cancer and helps maintain skin health; however, improper use can decrease its effectiveness. This study aimed to investigate the prevalence and factors associated with sunscreen use in Saudi Arabia as well as identifying areas of weakness in sunscreen practices. METHODS: A cross-sectional survey-based study was conducted with a diverse population sample in Saudi Arabia. Participants were asked about their sunscreen usage habits, motivations, and knowledge of proper application techniques. Demographic information, including age, gender, and skin type, were also collected. RESULTS: A total of 2321 individuals participated in the study. More than two-thirds of the participants reported using sunscreen either always, regularly, or often, primarily to maintain a light skin color and prevent skin cancer. Factors associated with sunscreen use included younger age (18-40 years old), female gender, history of sunburn, and fair skin. Despite the majority reporting healthy sun exposure habits, several shortcomings were identified in sunscreen practices, including incorrect application and suboptimal reapplication frequency. CONCLUSION: While sunscreen use is common among the study population, there is a need for improved education on proper application techniques. National awareness campaigns, especially those utilizing popular social media and digital platforms in Saudi Arabia, should focus on disseminating accurate sunscreen use guidelines to maximize sun protection and skin health.
