ABSTRACT

Background The competency-based undergraduate medical curriculum has a number of new elements. Few authors have attempted to understand the students’ viewpoints on the curriculum. We assessed undergraduate students perspectives and ratings about various elements after 2 years of implementation of the curriculum. Methods We included 240 students (2019 and 2020 admission). An invitation letter-cum-information sheet was sent to all the students by email informing them about the study, keeping their identity confidential and the implied consent. A validated questionnaire based on a 5-point Likert scale including 35 closed-ended questions eliciting the students’ perception on various elements of the new curriculum and a rating scale from 1 to 5 was designed. Data collection was done using Google forms. Results Of the 240 respondents, 192 (80%) had positive perceptions for the Foundation Course, Attitude, Ethics and Communication skills, Early Clinical Exposure and Community Health Visits. Integrated Teaching, Small Group Teaching and Assessments were viewed less positively (62.9%-75%) and Self-directed Learning received the lowest positive responses (57%-58%). For training as a doctor, the elements considered most valuable were Early Clinical Exposure (70.4%) and Community Health Visits (70.4%) while the least were Logbooks (35.5%) and Reflections (34.2%). Conclusions Students found Early Clinical Exposure and Community Health Visits the most valuable elements whereas Self-directed Learning, Logbooks and Reflections were rated as the least useful.

ABSTRACT

Background Evidence-based research aids in decision-making in the health sector for developing health policies for prevention, diagnosis and treatment of diseases. Medical research is not taught in the undergraduate curriculum. Studies show that attributes of research knowledge, awareness and practical involvement in research are low among undergraduate students. We developed and validated a module and trained undergraduate students in research skills through an inter-ventional workshop using the structured module. Methods We did this participatory action research with a mixed-methods approach in the Department of Community Medicine at Adesh Institute of Medical Sciences and Research, Bathinda, Punjab. A structured module was developed by the core committee and validated internally and externally. Pilot testing of the module was done by delivering it in the form of a workshop to 46 students. For statistical analysis, percentage agreements, validity indices, median (interquartile range), satisfaction percentages and Wilcoxon sign test were used. Results The structured and validated module was established to have high face validity (>90%) and content validity (CVI=0.975). The module was successfully pilot tested for delivery through both onsite and online modes. The satisfaction percentage with the workshop was 91% and 100% and overall rating of the module was 74% and 91% by interns and MBBS students, and 100% by faculty. The scores of knowledge and skills were found to be significantly higher on all variables post workshop with p<0.001. All students scored satisfactory grades for research skills. Conclusions Teaching research using a structured validated module improved the knowledge and skills related to research among students. Both students and faculty were satisfied with the use of the structured module.

ABSTRACT

Numerous studies have investigated the causes of falls in the elderly. However, there is little information about metabolic syndrome (MS) as a risk factor for falls in older adults. No evaluations have given a qualitative overview of studies examining the relationship between MS and falls in the elderly. We did a literature search in electronic databases to look for studies that assessed a link between MS and falls among people over the age of 55 years. We found three studies of high quality. These included 2774 people with an average age of 72 years. Even after controlling for other risk factors, two studies found that MS was significantly associated with an older adult’s 1.3-2.5-fold increased risk of falling. We found that MS and its independent components were strongly linked with falls among the elderly, even after correcting for numerous variables.

ABSTRACT

BACKGROUND Cephalometric radiography evaluates facial skeleton development and aids in diagnosis and treatment phases (pre and post) in orthodontics. This study aimed to compare digital cephalometric tracing using a smartphone application (App), a tablet-based platform, and manual tracing in 30 orthodontic patients. MATERIAL AND METHODS Thirty orthodontic pretreatment, criteria based, lateral cephalometric radiographs were analyzed/grouped for Steiner analysis parameters (5 skeletal, 3 dentals, 1 soft tissue) by 3 tracing methods [manual – group (Gp M), smartphone (Android – OS9) – Gp S, tablet (Apple – IOS13) – Gp T) after mandatory standardization/calibration. Measurements include 5 angular (SNA, SNB, ANB, SNMPA, SNOP), 3 linear U1NA, L1NB, U1L1, and 1 soft tissue (S line) (millimeters and degrees). Inter-examiner rating was determined using Dahlberg’s test. After normality distribution testing (Shapiro-Wilk), data were analyzed using one-way analysis of variance (ANOVA) for group differences. Homogeneity of variance was verified using the Levene test. Differences were determined on probability value of (p≤0.05). RESULTS The results showed that Steiner’s analysis parameters were similar in all groups with homogenous variances. Highest differences in mean values were found for L1NB, U1L1, and S line measurement, with higher values being observed in Gp S tracings. However, these differences were not statistically significant (p≤0.05). All parameters, irrespective of being measured in either degrees or millimeters, had means comparable to each other. CONCLUSIONS Smartphone and tablet-based applications produced tracings that were comparable and reliable when compared to conventional manual tracings. Standardization of images, processing, printing, and calibration of devices is important to achieve good results.

ABSTRACT

BACKGROUND: Doxorubicin (DXR) is an effective chemotherapeutic agent. DOX-induced cardiomyopathy (DICM), a major limitation of DXR, is a complication with limited treatment options. We previously reported that Red Ginseng (steamed and dried the root of Panax Ginseng cultivated for over six years; RGin) is beneficial for the treatment of DICM. However, the mechanism underlying the action of RGin remains unclear. In this study, we investigated the mechanism of action underlying the efficacy of RGin in the treatment of DICM.

METHODS: Four-week-old DBA/2 mice were divided into: vehicle, DXR, RGin, and DXR + RGin (n = 10/group). Mice were treated with DXR (4 mg/kg, once a week, accumulated 20 mg/kg, i.p.) or RGin (0.5 g/kg, three times a week, i.p.). To evaluate efficacy, the survival rate and left ventricular ejection fraction (LVEF) were measured as a measure of cardiac function, and cardiomyocytes were subjected to Masson trichrome staining. To investigate the mechanism of action, western blotting was performed to evaluate the expression of nuclear factor erythroid 2-related factor 2 (Nrf2), heme oxygenase 1, transferrin receptor (TfR), and other related proteins. Data were analyzed using the Easy R software. Between-group comparisons were performed using one-way analysis of variance and analyzed using a post-hoc Tukey test. Survival rates were estimated using the Kaplan-Meier method and compared using the log-rank test. P < 0.05 was considered statistically significant in all analyses.

RESULTS: RGin treatment prolongs survival and protects against reduced LVEF. In the DXR group, Nrf2 was not activated and cell death was accelerated. Furthermore, there was an increase in the TfR levels, suggesting abnormal iron metabolism. However, the DXR + RGin group showed activation of the Nrf2 pathway and suppression of myocardial cell death. Furthermore, there was no increase in TfR expression, suggesting that there were no abnormalities in iron metabolism. Therefore, the mechanism of action of RGin in DICM involves an increase in antioxidant activity and inhibition of cell death through activation of the Nrf2 pathway.

CONCLUSION: RGin is a useful therapeutic candidate for DICM. Its efficacy is supported by the activation of the Nrf2 pathway, which enhances antioxidant activity and inhibits cell death.

ABSTRACT

BACKGROUND: Previous Ethiopian literature on surgical capacity and challenges has focused on quantitative investigations, lacking contextual understanding. This explanatory sequential mixed-methods research (MMR) aimed to assess perioperative capacity and contextual challenges at three teaching hospitals in southern Ethiopia.

METHODS: A quantitative survey assessed workforce, infrastructure, service delivery, financing, and information systems. The survey findings were explained by qualitative semi-structured interviews of twenty perioperative providers. Descriptive statistics were integrated with qualitative thematic analysis findings using the narrative waving approach. Key findings from both datasets were linked using a joint display table.

RESULTS: The survey revealed shortages in the specialist workforce (with a ratio of 0.58 per 100,000 population), surgical volume (at 115 surgeries per 100,000 population), equipment, supplies, financing, and perioperative data tracking. Hospitals’ radiology services and blood products were only available 25-50% of the time, while anesthetic agents and essential laboratory services were often available 51-75% of the time. Perioperative management protocols were used rarely (1-25% of the time). Over 90% of patients lack health insurance coverage. Qualitative data also revealed scarcity of perioperative resources and equipment; unaffordable perioperative costs, lack of health insurance coverage, and unforeseen expenses; poor patient safety culture and communication barriers across the perioperative continuum of care; workforce shortages, job dissatisfaction, and concerns of competence; and weak national governance, and sociopolitical turmoil, and global market volatility exacerbating local challenges. These challenges are linked to risks in quality of care and patient safety, according to clinicians.

CONCLUSION: The study identifies deficiencies in the health system and sociopolitical landscape affecting safe surgery conduct. It highlights the need for comprehensive health system strengthening to expand workforce, upgrade facilities, improve safety culture, resilience, and leadership to ensure timely access to essential surgery. Exploring external factors, such as the impact of national governance and sociopolitical stability on reform efforts is also essential.

ABSTRACT

BACKGROUND: Aim of this study was to detect predictors of better adherence to the AgeWell.de-intervention, a two-year randomized multi-domain lifestyle intervention against cognitive decline.

METHODS: Data of 317 intervention group-participants comprising a risk group for dementia (Cardiovascular Risk Factors, Ageing and Dementia (CAIDE) score of ≥ 9; mean age 68.9 years, 49.5% women) from the AgeWell.de intervention study were analysed. Regression models with four blocks of predictors (sociodemographic, cognitive and psychosocial, lifestyle factors and chronic conditions) were run on adherence to the components of nutrition, enhancement of social and physical activity and cognitive training. Adherence to each component was operationalised by assessing the degree of goal achievement per component at up to seven time points during the intervention period, measured using a 5-point Likert scale (mean score of goal achievement).

RESULTS: Increasing age was negatively associated with adherence, while higher education positively predicted adherence. Participants with better mental state (Montreal Cognitive Assessment (MoCA)-score > 25) at baseline and higher self-efficacy adhered better. Diabetes and cardiovascular conditions were not associated with adherence, whereas smoking negatively affected adherence. Highest education and quitting smoking in the past were the only predictors associated with all four intervention components.

CONCLUSION: Results identified predictors for better and worse adherence. Particularly self-efficacy seems to be of considerable influence on adherence. This should be considered when designing future intervention trials.

ABSTRACT

BACKGROUND: Imported malaria continues to be reported in Sri Lanka after it was eliminated in 2012, and a few progress to life-threatening severe malaria.

METHODS: Data on imported malaria cases reported in Sri Lanka from 2013 to 2023 were extracted from the national malaria database maintained by the Anti Malaria Campaign (AMC) of Sri Lanka. Case data of severe malaria as defined by the World Health Organization were analysed with regard to patients’ general characteristics and their health-seeking behaviour, and the latter compared with that of uncomplicated malaria patients. Details of the last three cases of severe malaria in 2023 are presented.

RESULTS: 532 imported malaria cases were diagnosed over 11 years (2013-2023); 46 (8.6%) were severe malaria, of which 45 were Plasmodium falciparum and one Plasmodium vivax. Most severe malaria infections were acquired in Africa. All but one were males, and a majority (87%) were 26-60 years of age. They were mainly Sri Lankan nationals (82.6%). Just over half (56.5%) were treated at government hospitals. The average time between arrival of the person in Sri Lanka and onset of illness was 4 days. 29 cases of severe malaria were compared with 165 uncomplicated malaria cases reported from 2015 to 2023. On average both severe and uncomplicated malaria patients consulted a physician equally early (mean = 1 day) with 93.3% of severe malaria doing so within 3 days. However, the time from the point of consulting a physician to diagnosis of malaria was significantly longer (median 4 days) in severe malaria patients compared to uncomplicated patients (median 1 day) (p = 0.012) as was the time from onset of illness to diagnosis (p = 0.042). All severe patients recovered without sequelae except for one who died.

CONCLUSIONS: The risk of severe malaria among imported cases increases significantly beyond 5 days from the onset of symptoms. Although patients consult a physician early, malaria diagnosis tends to be delayed by physicians because it is now a rare disease. Good access to expert clinical care has maintained case fatality rates of severe malaria at par with those reported elsewhere.

ABSTRACT

BACKGROUND: This protocol outlines a scoping review with the objective of identifying and exploring planetary health considerations within existing health guidelines and health technology assessments (HTA). The insights gained from this review will serve as a basis for shaping future Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) guidance on planetary health.

METHODS: We will adhere to the JBI methodology for scoping reviews. We will conduct a comprehensive search and screening of results in all languages across various databases including MEDLINE, EMBASE, CINAHL, Global Health, Health Systems Evidence, Greenfile, and Environmental Issues. Additionally, we will supplement this search with resources such as the GIN library, BIGG database, Epistemonikos, GRADE guidelines repository, GRADEpro Guideline Development Tool Database, MAGICapp, NICE website, WHO websites, and a manual exploration of unpublished relevant documents using Google incognito mode. Two independent reviewers will screen and assess the full texts of identified documents according to the eligibility criteria. The following information from each full text will be extracted: document title; first author’s name; publication year; language; document type; document as a guideline or HTA; the topic/discipline; document purpose/study objective; developing/sponsoring organization; the country in which the study/guideline/HTA report was conducted; definition of planetary health or related concept provided; types of planetary health experts engaged; study methods; suggested methods to assess planetary health; use of secondary data on planetary health outcomes; description for use of life cycle assessment; description for assessing the quality of life cycle; population/intended audience; interventions; category; applicable planetary health boundaries; consideration of social justice/global equity; phase of intervention in life cycle related to planetary health addressed; the measure of planetary health impact; impact on biodiversity/land use; one health/animal welfare mention; funding; and conflict of interest. Data analysis will involve a combination of descriptive statistics and directed content analysis, with results presented in a narrative format and displayed in tables and graphs.

DISCUSSION: The final review results will be submitted to open-access peer-reviewed journals for publication when they become available. The research findings will also be disseminated at relevant planetary health conferences and workshops.
