Awareness and Perceptions Towards Menopause Among Saudi Women

Background : Menopause is an important period of women life .it is a normal physiological process, defined as the permanent cessation of menses for 12 months or more. Our study assess the awareness and perception of Saudi women aged from 30 to 65 years towards menopause and to Address the health needs of women to improve the quality of life of menopausal Saudi women. Methods: Cross sectional study by using survey distributed electronically through kingdom of Saudi Arabia for Saudi women between ages of 30-65 years old. Results: The number of participant were total of 738 women, 130 women were menopause already. Most of participant were from southern region (67%). Study shows that 51-55 years old is the average age of menopause. Our participant (41.9%) they choose the answer of “inability of ovary to produce egg “as definition of menopause while (17.6 %) choose “cessation of mensuration for more than 1 year), most of women (31.9 %) they though that psychological symptoms will be more prominent with significant p value (0.003), while among menopause group they choose hot flush as the most prominent symptoms (38.5%). About 70% of our sample they mention that they don’t have enough background about menopause. Conclusion: Heath education with proper medical advices should be a part of primary health clinics projects. Media and menopause groups play important role to help health provider

A comparative study between X-chromosome mapping of Sudanese and Egyptian Anopheles pharoensis theobald (Diptera: Culicidae) strains

Background: Current literature lacks information regarding Anopheles pharoensis malaria transmission patterns. Anopheles pharoensis succeeded in transmitting Malaria in Egypt. However, it was unsuccessful in doing the same in Sudan. From here arises these important questions: Why does it transmit malaria in Egypt but not in the Sudan or other Countries? Is it a Sibling species or a Sub-species? This investigation aimed to answer these questions by studying the genetics of Anopheles pharoensis collected from Egypt and Sudan.Methods: A comparative study was conducted in Egypt and Sudan to determine the population genetic structure of Anopheles pharoensis species based on chromosomal inversion of karyotypes. Fourth-stage larvae of Anopheles pharoensis were collected from Egypt (Faiyoum government) and from Sudan (Khartoum, Gezira and Sennar states).Result: Significant levels of differentiation were observed among the species studied.Conclusion: Investigations suggest that Anopheles pharoensis species collected from Egypt can transmit malaria due to the presence of an inversion in the X-chromosome. The lack of the aforementioned inversion probably prevented the transmission of malaria by Anopheles pharoensis in Sudan. The results above provide insight into malaria transmission patterns by Anopheles pharoensis. However, more needs to be done and hence it is recommended to undergo further research on genetics and morphological studies using molecular biological tool son Anopheles pharoensis in Sudan

Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-income, middle-income, and high-income countries: a multicentre, international, prospective cohort study

Summary Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. Methods We did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. Findings We included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung’s disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58·0%) were male. Median gestational age at birth was 38 weeks (IQR 36–39) and median bodyweight at presentation was 2·8 kg (2·3–3·3). Mortality among all patients was 37 (39·8%) of 93 in low-income countries, 583 (20·4%) of 2860 in middle-income countries, and 50 (5·6%) of 896 in high-income countries (p<0·0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90·0%] of ten in lowincome countries, 97 [31·9%] of 304 in middle-income countries, and two [1·4%] of 139 in high-income countries; p≤0·0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2·78 [95% CI 1·88–4·11], p<0·0001; middle-income vs high-income countries, 2·11 [1·59–2·79], p<0·0001), sepsis at presentation (1·20 [1·04–1·40], p=0·016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4–5 vs ASA 1–2, 1·82 [1·40–2·35], p<0·0001; ASA 3 vs ASA 1–2, 1·58, [1·30–1·92], p<0·0001]), surgical safety checklist not used (1·39 [1·02–1·90], p=0·035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1·96, [1·41–2·71], p=0·0001; parenteral nutrition 1·35, [1·05–1·74], p=0·018). Administration of parenteral nutrition (0·61, [0·47–0·79], p=0·0002) and use of a peripherally inserted central catheter (0·65 [0·50–0·86], p=0·0024) or percutaneous central line (0·69 [0·48–1·00], p=0·049) were associated with lower mortality. Interpretation Unacceptable differences in mortality exist for gastrointestinal congenital anomalies between lowincome, middle-income, and high-income countries. Improving access to quality neonatal surgical care in LMICs will be vital to achieve Sustainable Development Goal 3.2 of ending preventable deaths in neonates and children younger than 5 years by 2030

Ribociclib-Loaded Ethylcellulose-Based Nanosponges: Formulation, Physicochemical Characterization, and Cytotoxic Potential against Breast Cancer

In the present study, ribociclib-loaded nanosponges (RCNs) composed of ethylcellulose and polyvinyl alcohol were developed using an emulsion-solvent evaporation method. Preliminary evaluations of the developed RCNs (RCN1 to RCN7) were performed in terms of size, polydispersity index (PDI), zeta potential (ZP), entrapment efficiency (EE), and drug loading (DL), which allowed us to select the optimized formulation. RCN3 was selected as the optimized carrier system with particle size (363.5±4.8 nm), PDI (0.292±0.012), zeta potential (−18.5±0.05 mV), EE (81.35±1.64%), and DL (21.96±0.28%). Further, the optimized nanosponges (RCN3) were subjected to FTIR, XRD, DSC, and SEM studies, and results confirmed the proper encapsulation of the drug within the porous polymeric matrix. In vitro drug release studies showed that the drug release was significantly enhanced with a maximum drug release through RCN3 formulation (81.85±0.37%) and followed the Higuchi model. Moreover, the RCN3 system showed greater cytotoxicity than free ribociclib (RC) against MDA-MB-231 and MCF-7 breast cancer cell lines. The percentage of apoptosis induced by RCN3 was found significantly higher than that of free RC (p<0.05). Overall, ribociclib-loaded ethylcellulose nanosponges could be a potential nanocarrier to enhance the effectiveness of ribociclib in breast cancer treatment

PLGA-Based Nanomedicine: History of Advancement and Development in Clinical Applications of Multiple Diseases

Research on the use of biodegradable polymers for drug delivery has been ongoing since they were first used as bioresorbable surgical devices in the 1980s. For tissue engineering and drug delivery, biodegradable polymer poly-lactic-co-glycolic acid (PLGA) has shown enormous promise among all biomaterials. PLGA are a family of FDA-approved biodegradable polymers that are physically strong and highly biocompatible and have been extensively studied as delivery vehicles of drugs, proteins, and macromolecules such as DNA and RNA. PLGA has a wide range of erosion times and mechanical properties that can be modified. Many innovative platforms have been widely studied and created for the development of methods for the controlled delivery of PLGA. In this paper, the various manufacturing processes and characteristics that impact their breakdown and drug release are explored in depth. Besides different PLGA-based nanoparticles, preclinical and clinical applications for different diseases and the PLGA platform types and their scale-up issues will be discussed

Prevalence of depression in postmyocardial infarction patients in a tertiary care center in Riyadh

BACKGROUND: The coexistence of coronary artery disease (CAD) and depression is a growing concern, as both conditions lead to disability. Although depression is more prevalent in CAD patients than in the general population and has been associated with adverse cardiac outcomes, the underlying mechanisms linking depression and CAD are not yet fully understood. This study aims to assess the prevalence of depression in postmyocardial infarction (MI) patients as baseline data in Saudi Arabia. MATERIALS AND METHODS: A cross-sectional study was conducted at King Saud Medical City, Riyadh. The study population included male and female patients who had survived MI from January 2022 to June 2022. A sample size of 323 patients was initially planned, but only 249 patients could be included on account of exclusions. The patients underwent screening for depression using Patient Health Questionnaire-2 (PHQ-2), and those who were positive on screening were further assessed using the PHQ-9 according to DSM-5 criteria. Sociodemographic data, comorbidities, and previous cardiac interventions were collected from medical records. RESULTS: The mean age of the study participants was 57.15 years, and majority (76.6%) were males. The prevalence of previously diagnosed depression was 9.2%, and 5.2% of patients reported using antidepressant medication. According to the PHQ-9 scores, 33.33% had depression, 9% had moderate depression, and 2.4% had severe depression. There were significant associations between the severity of depression and previous CAD (P < 0.05), previous coronary artery bypass graft surgery (P < 0.05), and heart failure (P < 0.05). CONCLUSION: This study reveals a high prevalence of depression in post-MI patients at King Saud Medical City. The findings highlight the need for comprehensive management of depression in this population to improve outcomes. Further research into the underlying mechanisms linking depression and CAD to develop effective interventions is required

Development of Apremilast Nanoemulsion-Loaded Chitosan Gels: In Vitro Evaluations and Anti-Inflammatory and Wound Healing Studies on a Rat Model

Apremilast (APL) has profound anti-inflammatory and wound healing activity, alongside other dermal care. This study aims to develop APL-loaded NEs (ANE1-ANE5) using eucalyptus oil (EO) as the oil and Tween-80 and transcutol-HP (THP) as a surfactant and co-surfactant, respectively. The prepared NEs were then evaluated based on mean droplet size (12.63 &plusmn; 1.2 nm), PDI (0.269 &plusmn; 0.012), ZP (&minus;23.00 &plusmn; 5.86), RI (1.315 &plusmn; 0.02), and %T (99.89 &plusmn; 0.38) and ANE4 was optimized. Further, optimized NEs (ANE4) were incorporated into chitosan gel (2%, w/v). The developed ANE4-loaded chitosan gel was then evaluated for pH, spreadability, in vitro diffusion, and wound healing and anti-inflammatory studies. Moreover, in vivo studies denoted improved anti-inflammatory and wound healing activity and represented a decrease in wound size percentage (99.68 &plusmn; 0.345%) for the APNE2 gel test compared to a negative control (86.48 &plusmn; 0.87%) and standard control (92.82 &plusmn; 0.34%). Thus, the formulation of ANE4-loaded chitosan gels is an efficient topical treatment strategy for inflammatory and wound healing conditions
