Antimicrobial activity of three medicinal plants (Artemisia indica, Medicago falcate and Tecoma stans)
Background: Artemisia indica, Medicago falcata and Tecoma stans are traditionally being use for medicinal purposes in Pakistan. Present study was designed to check in-vitro efficacy of these plants against selected bacterial and fungal strains.Methodology: Chloroform, butanol, ethyl acetate and n-hexane extracts of these plants were used for antimicrobial screening. Antibacterial activity was tested against four pathogenic bacterial strains i.e. Escherichia coli, Pseudomonas aeruginosa, Salmonella typhi and Staphylococcus aureus while antifungal activity was tested against four fungal strains i.e. Aspergillus flavus, Aspergillus niger, Aspergillus fumigatus and Fusarium solani.Results: Chloroform, butanol and ethyl acetate extracts of Artemisia indica, Medicago falcata and Tecoma stans showed high inhibitory activities (between 15-20 mm) against E. coli, P. aeruginosa and S. aureus. However, all extracts of Artemisia indica showed inhibitory activities (12-14 mm) against Salmonella typhi. As antifungal activities, the n-Hexane and chloroform extracts of Artemisia indica have completely inhibited the growth of Aspergillus flavus and Fusariun solani, respectively. Ethyl acetate and butanol extract of Medicago falcata completely inhibited Fusarium solani and Aspergillus fumigates, respectively. The n-hexane extract of Tecoma stans completely inhibited Fusarium solani, while its ethyl acetate extract shows excellent activity against Aspergillus niger.Conclusions: These findings provide scientific evidence of traditional use of medicinal plants and also indicate the potential of these plants for the development of antimicrobial agents.Key words: Medicinal Plants, Traditional uses, phytochemical effects, Antimicrobial activity
Evaluating Service Satisfaction and Sustainability of the Afya Insurance Scheme in Kuwait: An Exploratory Analysis
Maha Alnashmi,1 Nuzhat Masud Bhuiyan,2 Nour AlFaham,3 Ahmad Salman,4 Hanadi AlHumaidi,1 Nabeel Akhtar1 1Health Informatics and Information Management Department, Faculty of Allied Health Sciences, Kuwait University, Jabriya, Kuwait; 2Department of Environmental Science and Management, School of Health and Life Sciences, North South University, Bashundhara, Bangladesh; 3Gulf University for Science and Technology, Mubarak Al-Abdullah, Kuwait; 4Public Health Practice, College of Public Health, Shadadiya, KuwaitCorrespondence: Nabeel Akhtar, Kuwait University, Faculty of Allied Health Sciences, HIIM Department, Kuwait, Email [email protected]: In 2014, the Kuwaiti parliament enacted the private health insurance law for Kuwaiti retirees ie, Afya to enhance service quality for retirees through the involvement of the private sector. The study aimed to comprehensively analyze Afya across three crucial dimensions: efficiency, inclusiveness, effectiveness, and service quality; delivery of services throughout the revenue management cycle; and its long-term sustainability in Kuwait.Methods: Conducted between June 2021 and August 2022, the study employed both web-based and hardcopy questionnaires, reaching a response rate of 78.79% from a random sample of 514 Kuwaiti beneficiaries holding Afya insurance cards. Exclusions were made for those who did not receive cards or declined participation, resulting in analysis of 405 completed surveys.Results: The findings revealed that 95% of participants frequently utilized services from private hospitals, with a corresponding 78.79% satisfaction rate. However, when seeking medical services from government hospitals, respondents often opted to repeat procedures to ensure accurate results and diagnoses. Despite a strong endorsement for enhancing Afya’s coverage plan (94%), over half of the respondents suggested a temporary suspension of the scheme to conduct thorough research and alleviate potential financial burdens on the government. Notably, a significant positive correlation (0.578, p < 0.01) was observed between beneficiary satisfaction and their experience with Afya coverage, underscoring the importance of aligning scheme operations with beneficiary needs.Conclusion: Addressing these disparities and improving access to healthcare services for retirees necessitate a thorough reformation of the Afya scheme. To address these challenges, the study recommends comprehensive reform through evidence-based research, enhanced information exchange mechanisms between public and private sectors, and broader coverage targeting younger demographics. These measures are crucial for ensuring the scheme’s efficacy, sustainability, and alignment with the evolving healthcare landscape in Kuwait.Keywords: health insurance, health policy, afya insurance scheme, Kuwai

Laparoscopy in management of appendicitis in high-, middle-, and low-income countries: a multicenter, prospective, cohort study.
BACKGROUND: Appendicitis is the most common abdominal surgical emergency worldwide. Differences between high- and low-income settings in the availability of laparoscopic appendectomy, alternative management choices, and outcomes are poorly described. The aim was to identify variation in surgical management and outcomes of appendicitis within low-, middle-, and high-Human Development Index (HDI) countries worldwide. METHODS: This is a multicenter, international prospective cohort study. Consecutive sampling of patients undergoing emergency appendectomy over 6 months was conducted. Follow-up lasted 30 days. RESULTS: 4546 patients from 52 countries underwent appendectomy (2499 high-, 1540 middle-, and 507 low-HDI groups). Surgical site infection (SSI) rates were higher in low-HDI (OR 2.57, 95% CI 1.33-4.99, p = 0.005) but not middle-HDI countries (OR 1.38, 95% CI 0.76-2.52, p = 0.291), compared with high-HDI countries after adjustment. A laparoscopic approach was common in high-HDI countries (1693/2499, 67.7%), but infrequent in low-HDI (41/507, 8.1%) and middle-HDI (132/1540, 8.6%) groups. After accounting for case-mix, laparoscopy was still associated with fewer overall complications (OR 0.55, 95% CI 0.42-0.71, p < 0.001) and SSIs (OR 0.22, 95% CI 0.14-0.33, p < 0.001). In propensity-score matched groups within low-/middle-HDI countries, laparoscopy was still associated with fewer overall complications (OR 0.23 95% CI 0.11-0.44) and SSI (OR 0.21 95% CI 0.09-0.45). CONCLUSION: A laparoscopic approach is associated with better outcomes and availability appears to differ by country HDI. Despite the profound clinical, operational, and financial barriers to its widespread introduction, laparoscopy could significantly improve outcomes for patients in low-resource environments.

Prognostic model to predict postoperative acute kidney injury in patients undergoing major gastrointestinal surgery based on a national prospective observational cohort study.
Background: Acute illness, existing co-morbidities and surgical stress response can all contribute to postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. The aim of this study was prospectively to develop a pragmatic prognostic model to stratify patients according to risk of developing AKI after major gastrointestinal surgery. Methods: This prospective multicentre cohort study included consecutive adults undergoing elective or emergency gastrointestinal resection, liver resection or stoma reversal in 2-week blocks over a continuous 3-month period. The primary outcome was the rate of AKI within 7 days of surgery. Bootstrap stability was used to select clinically plausible risk factors into the model. Internal model validation was carried out by bootstrap validation. Results: A total of 4544 patients were included across 173 centres in the UK and Ireland. The overall rate of AKI was 14·2 per cent (646 of 4544) and the 30-day mortality rate was 1·8 per cent (84 of 4544). Stage 1 AKI was significantly associated with 30-day mortality (unadjusted odds ratio 7·61, 95 per cent c.i. 4·49 to 12·90; P < 0·001), with increasing odds of death with each AKI stage. Six variables were selected for inclusion in the prognostic model: age, sex, ASA grade, preoperative estimated glomerular filtration rate, planned open surgery and preoperative use of either an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. Internal validation demonstrated good model discrimination (c-statistic 0·65). Discussion: Following major gastrointestinal surgery, AKI occurred in one in seven patients. This preoperative prognostic model identified patients at high risk of postoperative AKI. Validation in an independent data set is required to ensure generalizability
Transformational school leadership as a key factor for teachers’ job attitudes during their first year in the profession
Teacher attrition is a global concern that is particularly prevalent among beginning teachers. Teachers' intrinsic motivation to teach, affective organisational commitment and job satisfaction are considered job attitudes that stop them from dropping out of the profession. This study explores the interplay between factors at the school level (i.e. transformational leadership of the principal, professional collegial support) and the teacher level (i.e. self-efficacy) influencing these job attitudes. A sample of 292 first-year primary-school teachers participated. The results of the path analysis demonstrated that transformational leadership of the principal is directly related to teachers' job attitudes in a positive way. Moreover, transformational leadership of the principal is also indirectly related to these attitudes, via both professional collegial support and teachers' self-efficacy. Implications for the supportive role of the principal in the teachers' first year in the profession are discussed
Relation between body mass index and depression: a structural equation modeling approach
<p>Abstract</p> <p>Background</p> <p>Obesity and depression are two major diseases which are associated with many other health problems such as hypertension, dyslipidemia, diabetes mellitus, coronary heart disease, stroke, myocardial infarction, heart failure in patients with systolic hypertension, low bone mineral density and increased mortality. Both diseases share common health complications but there are inconsistent findings concerning the relationship between obesity and depression. In this work we used the <it>structural equation modeling </it>(SEM) technique to examine the relation between body mass index (BMI), as a proxy for obesity, and depression using the Canadian Community Health Survey, Cycle 1.2.</p> <p>Methods</p> <p>In this SEM model we postulate that 1) BMI and depression are directly related, 2) BMI is directly affected by the physical activity and, 3)depression is directly influenced by stress. SEM was also used to assess the relation between BMI and depression separately for males and females.</p> <p>Results</p> <p>The results indicate that higher BMI is associated with more severe form of depression. On the other hand, the more severe form of depression may result in less weight gain. However, the association between depression and BMI is gender dependent. In males, the higher BMI may result in a more severe form of depression while in females the relation may not be the same. Also, there was a negative relationship between physical activity and BMI.</p> <p>Conclusion</p> <p>In general, use of SEM method showed that the two major diseases, obesity and depression, are associated but the form of the relation is different among males and females. More research is necessary to further understand the complexity of the relationship between obesity and depression. It also demonstrated that SEM is a feasible technique for modeling the relation between obesity and depression.</p
Is plasma vitamin C an appropriate biomarker of vitamin C intake? A systematic review and meta-analysis
<p>Abstract</p> <p>Background</p> <p>As the primary source of dietary vitamin C is fruit and to some extent vegetables, the plasma level of vitamin C has been considered a good surrogate or predictor of vitamin C intake by fruit and vegetable consumption. The purpose of this systematic review was to investigate the relationship between dietary vitamin C intakes measured by different dietary methods and plasma levels of vitamin C.</p> <p>Method</p> <p>We searched the literature up to May 2006 through the OVID interface: MEDLINE (from 1960) and EMBASE (from 1988). We also reviewed the reference lists in the articles, reviews, and textbooks retrieved. A total of 26 studies were selected and their results were combined using meta-analytic techniques with random-effect model approach.</p> <p>Results</p> <p>The overall result of this study showed a positive correlation coefficient between Food Frequency Questionnaire (FFQ) and biomarker (<it>r </it>= 0.35 for "both" genders, 0.39 for females, and 0.46 for males). Also the correlation between Dietary Recalls (DR)/diary and biomarker was 0.46 for "both" genders, 0.44 for females, and 0.36 for males. An overall correlation of 0.39 was found when using the weight record method. Adjusting for energy intake improved the observed correlation for FFQ from 0.31 to 0.41. In addition, we compared the correlation for smokers and non-smokers for both genders (FFQ: for non-smoker <it>r </it>= 0.45, adjusted for smoking <it>r </it>= 0.33).</p> <p>Conclusion</p> <p>Our findings show that FFQ and DR/diary have a moderate relationship with plasma vitamin C. The correlation may be affected/influenced by the presence of external factors such as vitamin bioavailability, absorption condition, stress and food processing and storage time, or by error in reporting vitamin C intake.</p
Optical Imaging of Bacterial Infections
The rise in multidrug resistant (MDR) bacteria has become a global crisis. Rapid and accurate diagnosis of infection will facilitate antibiotic stewardship and preserve our ability to treat and cure patients from bacterial infection. Direct in situ imaging of bacteria offers the prospect of accurately diagnosing disease and monitoring patient outcomes and response to treatment in real-time. There have been many recent advances in the field of optical imaging of infection; namely in specific probe and fluorophore design. This combined with the advances in imaging device technology render direct optical imaging of infection a feasible approach for accurate diagnosis in the clinic. Despite this, there are currently no licensed molecular probes for clinical optical imaging of infection. Here we report some of the most promising and interesting probes and approaches under development for this purpose, which have been evaluated in in vivo models within the laboratory setting
RNA interference approaches for treatment of HIV-1 infection
HIV/AIDS is a chronic and debilitating disease that cannot be cured with current antiretroviral drugs. While combinatorial antiretroviral therapy (cART) can potently suppress HIV-1 replication and delay the onset of AIDS, viral mutagenesis often leads to viral escape from multiple drugs. In addition to the pharmacological agents that comprise cART drug cocktails, new biological therapeutics are reaching the clinic. These include gene-based therapies that utilize RNA interference (RNAi) to silence the expression of viral or host mRNA targets that are required for HIV-1 infection and/or replication. RNAi allows sequence-specific design to compensate for viral mutants and natural variants, thereby drastically expanding the number of therapeutic targets beyond the capabilities of cART. Recent advances in clinical and preclinical studies have demonstrated the promise of RNAi therapeutics, reinforcing the concept that RNAi-based agents might offer a safe, effective, and more durable approach for the treatment of HIV/AIDS. Nevertheless, there are challenges that must be overcome in order for RNAi therapeutics to reach their clinical potential. These include the refinement of strategies for delivery and to reduce the risk of mutational escape. In this review, we provide an overview of RNAi-based therapies for HIV-1, examine a variety of combinatorial RNAi strategies, and discuss approaches for ex vivo delivery and in vivo delivery
