Professionalism-training in undergraduate medical education in a multi-cultural, multi-ethnic setting in the Gulf Region: an exploration of reflective essays.

BACKGROUND: Despite the established need to prioritize professionalism-training in developing future physicians, very few medical programs in the Gulf Region embed in their curricula discrete contextualized courses aimed at developing the corresponding competencies, while fostering self-directed learning. This study aims at exploring the perception of undergraduate medical students in a multi-cultural, multi-ethnic setting regarding their understanding of, and personal experience with professionalism through their engagement with the content of an innovative curriculum-based professionalism course, offered at a Medical School in Dubai, United Arab Emirates. METHODS: The study used a qualitative phenomenological research design. Out of 33 students, 29 students had submitted reflective essays. The content of these essays was inductively analyzed following a six-step framework for conducting thematic analysis. The framework's steps include familiarizing oneself with the data, generating initial codes, searching for themes, reviewing themes, defining and naming themes, and producing the report. FINDINGS: The inductive qualitative analysis generated the Professionalism Learning Journey model. This conceptual model includes four interconnected themes: Awareness, Acknowledgement, Realization, and Application. The generated model depicts the trajectory that the learners appear to experience while they are engaging with the content of the course. CONCLUSION: Integrating a professionalism-training course into an undergraduate medical curriculum is likely to be positively appraised by the learners. It raises their awareness, enables them to value the subject matter and the sophistication of its application, and empowers them to put into practice the taught principles, on an individual basis and collectively. This is especially true when the course is entrenched in constructivism experiential learning theory and designed to foster self-directed learning. The introduced conceptual model, in conjunction with the innovative professionalism-training course curriculum, can serve as a template for other competencies and other schools.

Tracking Risk Factors Related to an Outbreak of COVID-19 Among Healthcare Workers in a General Medicine Ward.

Background An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection occurred in a medical ward involving patients and hospital staff from May to June 2020. Aim The aim of this study is to determine risk factors related to the outbreak of SARS-CoV-2 in six healthcare workers (HCWs) in a medical ward with initially unrecognized coronavirus disease 2019 (COVID-19) positive patients. Methods A retrospective cross-sectional study was conducted using a comprehensive questionnaire and personal interviews to determine the risk factors for COVID-19 infection in HCWs. Findings A total of 6/34 HCWs were diagnosed with COVID-19 in a medical ward. There were no differences between COVID-19 negative HCWs and COVID-19 positive HCWs in terms of mean duration of hours worked in the unit during the cluster event (180.2 vs 177.5 hours) (p>0.05), mean total time spent in contact with COVID-19 positive patients (12.8 vs 10.5 hours) (p>0.05), mean total time spent on aerosol-generating procedures (1.9 vs 0.9 hours) (p>0.05), and mean total time spent on non-aerosol generating procedures (10.9 vs 9.6 hours ) (p>0.05). There was no difference in exposure to COVID-19 positive family members among the HCWs (33% vs 3.7%, p=0.08). In contrast, exposure to COVID-19 positive contacts in the community was significantly greater in infected vs non-infected HCWs (16.7% vs 0%, p=0.03). Conclusion There was no significant difference in risk factors for contracting SARs-CoV2 among HCWs due to hospital exposures. COVID-19 positive HCWs were more likely to be exposed to positive individuals in their households and community, indicating that the source of SARS-CoV-2 infection came from outside the hospital.

An Inquiry-Based Distance Learning Tool for Medical Students Under Lockdown ("COVID-19 Rounds"): Cross-Sectional Study.

BACKGROUND: The COVID-19 pandemic presented significant challenges to both clinical practice and the delivery of medical education. Educators and learners implemented novel techniques, including distance learning and web-based rounds, while trying to stay updated with the surge of information regarding COVID-19 epidemiology, pathogenesis, and treatment. Hence, we designed and implemented a technologically enhanced course called "COVID-19 Rounds" to educate students about the rapidly evolving pandemic. OBJECTIVE: The objectives of this study are to describe a technologically enhanced course called "COVID-19 Rounds" and evaluate the following: (1) student satisfaction and program usefulness in achieving preset objectives, (2) perceived improvement in literacy regarding the pandemic, and (3) the impact of student engagement by designing infographics and initiating COVID-19-related research projects. METHODS: This is a cross-sectional study measuring the impact of the implementation of the web-based "COVID-19 Rounds" course. This program included web-based clinical experiences with physicians on actual rounds in COVID-19 wards in the hospital, weekly updates on evolving data and new research, and engagement in student-led projects. The study population included 47 fourth-year medical students at the Mohamed Bin Rashid University of Medicine and Health Sciences in Dubai, the United Arab Emirates, who attended the course. We designed and administered a 47-item survey to assess student satisfaction, program usefulness, impact on knowledge, and student engagement. Data were collected at the end of program delivery via Microsoft Forms. RESULTS: In total, 38 (81%) out of 47 fourth-year medical students participated in this study. The final course evaluation revealed an overall high satisfaction rate, with a mean rating of 3.9 (SD 0.94) on the 5-point Likert scale. Most students were satisfied with the course format (27/38, 71%), organization (31/38, 82%), and the learning experience (28/38, 74%) that the course offered. The course was particularly appreciated for offering evidence-based talks about aspects of the pandemic (34/38, 90%), providing weekly updates regarding emerging evidence (32/38, 84%), and enhancing understanding of the challenges of the pandemic (34/38, 90%). Satisfaction with distance learning was moderate (23/37, 62%), and a minority of students would have preferred an in-person version of the course (10/37, 27%). Student engagement in the course was high. All students participated in small group presentations of infographics of pandemic-related topics. Perceived advantages included conciseness and visual appeal, and disadvantages included the lack of detail and the time-consuming nature of infographic design, especially for students with no prior design experience. After the course ended, 27 (57%) students began research projects. This resulted in 6 abstracts presented at local meetings and 8 scientific papers published or submitted for publication. CONCLUSIONS: This inquiry-based adaptive approach to educating medical students about updates on COVID-19 via web-based learning was successful in achieving objectives and encouraging engagement in research. However, shortcomings of the course related to the lack of in-person teaching and clinical activities were also highlighted.

Clinical and epidemiological features and severity markers in children admitted with multisystem inflammatory syndrome in children (MISC) in a tertiary care center in the United Arab Emirates.

BACKGROUND: Multisystem inflammatory syndrome in children (MISC) is a phenomenon that appeared in children infected with or exposed to severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2). The typical onset of MISC is 4-6 weeks following SARS-CoV-2 infection and is formulated to be due to an immune response. METHODS: Our study retrospectively analyzed data from a tertiary center in United Arab Emirates of MISC patients who were admitted to either general pediatric wards or pediatric intensive care (PICU) or who came exclusively for follow-up (post-PICU admission) from May 2020 to August 2021. RESULTS: The total sample size was 50 patients, and the study included a comparison of MISC-PICU admissions with MISC-non-PICU admissions. The MISC-PICU sample size was 18 patients, 50% females, with mean age of 8.3 years all were previously healthy. MISC-PICU patients had deranged blood counts with a lower hemoglobin count, a more pronounced lymphopenia and thrombocytopenia along with hypoalbuminemia. MISC-PICU patients presented with relatively higher inflammatory markers: C-reactive protein, procalcitonin, ferritin, and d-dimer. Immunological studies were significantly higher for interleukin-6 levels in PICU patients. On echocardiography, higher myocardial dysfunction was more notable in MISC-PICU patients. Likewise, MISC-PICU patients were provided with more extensive therapy. As part of our study course, we reevaluated our MISC-PICU patients twice, once at 48 h post-PICU admission and again 4-6 weeks after discharge from the hospital. No deaths have been recorded in the cohort. CONCLUSION: This study evaluated risk factors of MISC and potential severity features. Follow-up of patients on discharge showed improvement across all domains.

Potential enhancement of post-stroke angiogenic response by targeting the oligomeric aggregation of p53 protein.

Tumor suppressor gene p53 and its aggregate have been found to be involved in many angiogenesis-related pathways. We explored the possible p53 aggregation formation mechanisms commonly occur after ischemic stroke, such as hypoxia and the presence of reactive oxygen species (ROS). The angiogenic pathways involving p53 mainly occur in nucleus or cytoplasm, with one exception that occurs in mitochondria. Considering the high mitochondrial density in brain and endothelial cells, we proposed that the cyclophilin D (CypD)-dependent vascular endothelial cell (VECs) necrosis pathway occurring in the mitochondria is one of the major factors that affects angiogenesis. Hence, targeting p53 aggregation, a key intermediate in the pathway, could be an alternative therapeutic target for post-stroke management.

Clinical learning environments across two different healthcare settings using the undergraduate clinical education environment measure.

BACKGROUND: The clinical placements of our medical students are almost equally distributed across private and public sectors. This study aims to assess medical students' perceptions of their Clinical learning Environment (CLE) across these two different healthcare settings, using the Undergraduate Clinical Education Environment Measure (UCEEM). METHODS: 76 undergraduate medical students (Year 5 and 6), were invited to participate. Data were collected using an online UCEEM with additional questions related to demographics and case load exposure. The UCEEM consists of two overarching domains of experiential learning and social participation, with four subdomains of learning opportunities, preparedness, workplace interaction, and inclusion. RESULTS: 38 questionnaires were received. Of 225 responses to the individual UCEEM items, 51 (22.6%) scored a mean of ≥ 4 (range 4-4.5, representing strong areas), 31 (13.7%) scored a mean of ≤ 3 (range 2.1-3, needing attention) and 143 (63.6%) scored a mean of 3.1-3.9 (areas that could be improved). The majority (63%) of the case load exposure responses scored a mean of ≥ 4 (range 4-4.5). Compared to the private sittings, there is a significant reduction in total UCEEM (p = 0.008), preparedness for student entry (p = 0.003), and overarching dimension of social participation (p = 0.000) scores for the public sector. Similarly, both workplace interaction patterns and student inclusion and equal treatment scored significantly lower for the public sector (p = 0.000 and p = 0.011 respectively). Two out of three case load exposure items scored significantly higher for the public sector (p = 0.000). DISCUSSION: The students' CLE perceptions were generally positive. The lower UCEEM ratings in the public sector items were related to student entry preparedness, workplace interactions, student inclusiveness and workforce equity of treatment. In contrast the students were exposed to more variety and larger number of patients in the public sector. These differences indicated some significantly different learning environments between the two sectors.

Bereavement, Memorial Attendance, and Mental Health During the COVID-19 Pandemic: Longitudinal Results from the Nurses' Health Study.

BACKGROUND: Mortality increased during the COVID-19 pandemic. Many bereaved individuals were not able to gather to memorialize their loved ones, yet it is unknown if this contributed to worsening mental health. OBJECTIVE: Examine the association of bereavement in the early part of the COVID-19 pandemic with subsequent psychological distress and the role of memorial attendance in reducing psychological distress among the bereaved. DESIGN, SETTINGS, SUBJECTS: In May 2020, 39,564 older females from the Nurses' Health Study II enrolled in a longitudinal COVID-19 substudy (meanage = 65.2 years, SD = 4.5). METHODS: Linear regression analyses estimated associations of bereavement reported between March and October, 2020 with subsequent psychological distress between January and October 2021, adjusting for sociodemographic and prepandemic depression symptoms. Secondary models examined associations between memorial attendance and psychological distress. RESULTS: Bereavement during the early part of the COVID-19 pandemic was associated with higher psychological distress (adjusted ß = 0.21, 95% CI: 0.15, 0.26) assessed over the next year. Among the bereaved, memorial attendance was associated with lower psychological distress (in-person: adjusted ß = -0.41, 95% CI: -0.53, -0.29; online: adjusted ß = -0.24, 95% CI: -0.46, --0.02). CONCLUSION: Attending memorials was associated with lower subsequent psychological distress among bereaved older females.

The COVID-19 Pandemic and Health and Care Workers: Findings From a Systematic Review and Meta-Analysis (2020-2021).

Objectives: The COVID-19 pandemic has greatly impacted health and care workers (HCW) globally, whom are considered at greater risk of infection and death. This study aims to document emerging evidence on disease prevalence, clinical outcomes, and vaccination rates of HCWs. Methods: Three databases were surveyed resulting on 108 final articles between July-December 2020 (period 1) and January-June 2021 (period 2). Results: Amongst the overall 980,000 HCWs identified, in period 1, the estimates were 6.1% (95% CI, 4.1-8.8) for the PCR positivity rate. Regarding outcomes, the hospitalization prevalence was 1.6% (95% CI, 0.7-3.9), and mortality rate of 0.3% (95% CI, 0.1-0.8). In period 2, the PCR positivity rate was 8.1% (95% CI, 4.6-13.8). Analysis of outcomes revealed a hospitalization rate of 0.7% (95% CI 0.3-1.8), and average mortality rate of 0.3% (95% CI 0.1-0.9). Our analysis indicated a HCW vaccination rate of 59.0% (95% CI, 39.4-76.1). Conclusion: Studies from the latter half of 2020 to the first half of 2021 showed a slight increasing trend in PCR positivity among HCW, along with improved clinical outcomes in the 1-year period of exposure. These results correlate well with the improving uptake of COVID-19 vaccination globally.

Effects of Leea indica leaf extracts and its phytoconstituents on natural killer cell-mediated cytotoxicity in human ovarian cancer.

BACKGROUND: The rich biodiversity of medicinal plants and their importance as sources of novel therapeutics and lead compounds warrant further research. Despite advances in debulking surgery and chemotherapy, the risks of recurrence of ovarian cancer and resistance to therapy are significant and the clinical outcomes of ovarian cancer remain poor or even incurable. OBJECTIVE: This study aims to investigate the effects of leaf extracts from a medicinal plant Leea indica and its selected phytoconstituents on human ovarian cancer cells and in combination with oxaliplatin and natural killer (NK) cells. METHODS: Fresh, healthy leaves of L. indica were harvested and extracted in 70% methanol by maceration. The crude extract was partitioned with n-hexane, dichloromethane and ethyl acetate. Selected extracts and compounds were analyzed for their effects on cell viability of human ovarian cancer cells, NK cell cytotoxicity, and stress ligands expression for NK cell receptors. They were also evaluated for their effects on TNF-α and IL-1ß production by enzyme-linked immunosorbent assay in lipopolysaccharide-stimulated human U937 macrophages. RESULTS: Leaf extracts of L. indica increased the susceptibility of human ovarian tumor cells to NK cell-mediated cytotoxicity. Treatment of cancer cells with methyl gallate but not gallic acid upregulated the expression of stress ligands. Tumor cells pretreated with combination of methyl gallate and low concentration of oxaliplatin displayed increased levels of stress ligands expression and concomitantly enhanced susceptibility to NK cell-mediated cytolysis. Further, NK cells completely abrogated the growth of methyl gallate-pretreated ovarian cancer cells. The leaf extracts suppressed TNF-α and IL-1ß production in human U937 macrophages. Methyl gallate was more potent than gallic acid in down-regulating these cytokine levels. CONCLUSIONS: We demonstrated for the first time that leaf extracts of L. indica and its phytoconstituent methyl gallate enhanced the susceptibility of ovarian tumor cells to NK cell cytolysis. These results suggest that the combined effect of methyl gallate, oxaliplatin and NK cells in ovarian cancer cells warrants further investigation, for example for refractory ovarian cancer. Our work is a step towards better scientific understanding of the traditional anticancer use of L. indica.

Medical students' perception of resilience and of an innovative curriculum-based resilience skills building course: A participant-focused qualitative analysis.

BACKGROUND: Medicine is one of the most demanding academic fields with an extensive curriculum that entails plenty of potential stressors. There is sufficient evidence that medical students are more prone to psychological distress when compared to their peer group of other disciplines. Despite the established need to prioritize resilience skills building within the medical curriculum, very few medical programmes in the Middle East and North Africa region (MENA) proactively empower the students to help themselves in sustaining their mental health. The purpose of the current study is to explore the perception of medical students in Dubai, United Arab Emirates (UAE) regarding their understanding of, and personal experience with building resilience, and their engagement with the content of an innovative curriculum-based resilience skills building course, designed in alignment with the constructivism theory of education. METHOD: The current study utilized a qualitative phenomenological research design. The curriculum-based resilience skills building course, that was investigated as part of this study, is offered at a medical school in Dubai, UAE. A total of 37 students submitted reflective essays about resilience building, in general, and the respective course, in specific. The collected data was inductively analysed following a six-step framework. FINDINGS: The qualitative analysis generated three interlinked themes, namely: Awareness, Application, and Appraisal. CONCLUSION: This study showed that integrating a resilience skills building course into medical curricula is likely to be positively appraised by the students, where it raises their level of awareness and likelihood of proactively applying the learned concepts in their daily lives. This is especially true when the course is anchored in constructivism experiential learning theory and designed to foster self-directed learning.

Study protocol for a pilot randomized, double-blind, placebo-controlled trial to investigate the anti-inflammatory effects of Frondanol in adults with inflammatory bowel disease.

Introduction: Inflammatory bowel disease (IBD), consisting of Crohn's disease and ulcerative colitis, is a debilitating condition with a rising incidence globally over recent years. Frondanol, a widely available nutraceutical extract of the edible sea cucumber Cucumaria frondosa has been reported to possess potent anti-inflammatory effects, likely mediated by the inhibition of 5-lipoxygenase and 12-lipoxygenase pathways, whilst showing no signs of toxicity. The potent anti-inflammatory effects of Frondanol in a mouse model of IBD provide encouragement for investigating its effects in human IBD patients. Here we describe the study protocol of a pilot randomized, double-blinded, placebo-controlled trial of Frondanol in patients with mild to moderate IBD who are on standard therapy. Material and methods: One hundred patients will be randomized (1:1) to receive Frondanol or placebo as an adjunct to their standard therapy for the period of six months. Blood and stool samples will be obtained during routine visits at baseline, and after three months and six months of treatment, and tissue samples from colon biopsies will be obtained during clinically indicated colonoscopies at baseline and after six months of treatment. The levels of inflammatory markers will be compared in serum and tissue samples between patients treated with Frondanol and those treated with placebo, and findings will be correlated with clinical and histological parameters. Discussion: If proven beneficial, treatment with Frondanol may increase the likelihood of patients remaining in remission and potentially provide an effective, natural and safe addition/alternative for treatment-naive patients in the future.(Clinical trial registration number: NCT05194007).

Paradoxical Increase of Permeability and Lipophilicity with the Increasing Topological Polar Surface Area within a Series of PRMT5 Inhibitors.

An imidazolone → triazolone replacement addressed the limited passive permeability of a series of protein arginine methyl transferase 5 (PRMT5) inhibitors. This increase in passive permeability was unexpected given the increase in the hydrogen bond acceptor (HBA) count and topological polar surface area (TPSA), two descriptors that are typically inversely correlated with permeability. Quantum mechanics (QM) calculations revealed that this unusual effect was due to an electronically driven disconnect between TPSA and 3D-PSA, which manifests in a reduction in overall HBA strength as indicated by the HBA moment descriptor from COSMO-RS (conductor-like screening model for real solvation). HBA moment was subsequently deployed as a design parameter leading to the discovery of inhibitors with not only improved passive permeability but also reduced P-glycoprotein (P-gp) transport. Our case study suggests that hidden polarity as quantified by TPSA-3DPSA can be rationally designed through QM calculations.

Active and avoidant coping profiles in children and their relationship with anxiety and depression during the COVID-19 pandemic.

Active and avoidant coping styles are important dispositional factors in the development of anxiety and depression symptoms. Children use both active and avoidant coping strategies together in daily life. No studies have investigated the relationship between active-avoidant coping profiles and internalizing symptoms in children. The present study aimed to investigate children's active-avoidant coping profiles and assess the relationship that active-avoidant coping profiles have with anxiety and depression symptoms. A two-wave longitudinal study was conducted among 322 Chinese children in the People's Republic of China during the COVID-19 pandemic. Participants completed the Children's Coping Strategies Checklist-Revised 1 at Time 1 and the Revised Child Anxiety and Depression Scale at Time 1 and 6 months later (Time 2). Four active-avoidant coping profiles were revealed: low active copers, high active copers, balanced copers, and avoidant copers. Low and high active copers had lower levels of anxiety and depression symptoms than balanced copers and avoidant copers. Avoidant copers showed a larger decrease in depression symptoms than balanced copers and high active copers during the COVID-19 pandemic. It is important to improve children's active-avoidant coping profiles to relieve anxiety and depression symptoms.

Intestinal transgene delivery with native E. coli chassis allows persistent physiological changes.

Live bacterial therapeutics (LBTs) could reverse diseases by engrafting in the gut and providing persistent beneficial functions in the host. However, attempts to functionally manipulate the gut microbiome of conventionally raised (CR) hosts have been unsuccessful because engineered microbial organisms (i.e., chassis) have difficulty in colonizing the hostile luminal environment. In this proof-of-concept study, we use native bacteria as chassis for transgene delivery to impact CR host physiology. Native Escherichia coli bacteria isolated from the stool cultures of CR mice were modified to express functional genes. The reintroduction of these strains induces perpetual engraftment in the intestine. In addition, engineered native E. coli can induce functional changes that affect physiology of and reverse pathology in CR hosts months after administration. Thus, using native bacteria as chassis to "knock in" specific functions allows mechanistic studies of specific microbial activities in the microbiome of CR hosts and enables LBT with curative intent.

Drug-induced acute pancreatitis in a bodybuilder: a case report.

BACKGROUND: Unregulated use of a variety of drugs and supplements by bodybuilders and athletes is common and can lead to severe adverse complications. Only a small proportion of acute pancreatitis cases are drug induced, and case reports are essential for identifying potential drug-related risks for pancreatitis. Here we present the first case report published of acute pancreatitis linked to recreational use of anabolic-androgenic steroids, subcutaneous growth hormone, and clenbuterol in a previously healthy male after excluding all other causes of pancreatitis. CASE PRESENTATION: A 31-year-old Arab male bodybuilder presented with acute abdominal pain associated with nausea and sharp pain radiating to the back. The patient was not using tobacco or alcohol but was using multiple drugs related to bodybuilding, including anabolic-androgenic steroids, subcutaneous growth hormone, clenbuterol, and multiple vitamin supplements. Laboratory studies revealed a normal white blood cell count, elevated C-reactive protein, minimally elevated aspartate aminotransferase and total bilirubin with normal remaining liver tests, and elevated amylase and lipase. The patient had no hypertriglyceridemia or hypercalcemia, and had had no recent infections, abdominal procedures, trauma, or scorpion exposure. Imaging and laboratory investigations were negative for biliary disease and IgG4 disease. Abdominal computed tomography revealed hepatomegaly and diffuse thickening and edema of the body and tail of the pancreas with peripancreatic fat stranding. An abdominal ultrasound showed slight hepatomegaly with no evidence of cholelithiasis. Genetic testing for hereditary pancreatitis-related mutations was negative. A diagnosis of drug-induced acute pancreatitis was made, and he was treated with aggressive intravenous hydration and pain management. The patient has avoided further use of these drugs and supplements and had no further episodes of pancreatitis during 1 year of follow-up. CONCLUSIONS: This case describes a patient with drug-induced acute pancreatitis after the intake of anabolic-androgenic steroids, subcutaneous growth hormone, and clenbuterol, where all other common causes of acute pancreatitis were excluded. Clinicians should be alert to the possibility of drug-induced acute pancreatitis occurring in bodybuilders and athletes using similar drug combinations.

Suffering, psychological distress, and well-being in Indonesia: A prospective cohort study.

Research on the subjective experience of suffering has typically focussed on older clinical samples living in Western, educated, industrialised, rich, and democratic (WEIRD) countries. To further extend the existing body of empirical research on suffering to less WEIRD contexts, we use three waves of data (Wave 1: December 2020; Wave 2: January 2021; Wave 3: February 2021) from a sample of nonclinical Indonesian adults (n = 594) to examine associations between suffering, two indices of psychological distress, and 10 facets of well-being. In our primary analysis, we estimated a series of multiple regression models that adjusted for a range of sociodemographic characteristics, financial and material stability, religious/spiritual factors, prior values of overall suffering, and prior values of each outcome assessed in Wave 1. Results indicated that overall suffering assessed in Wave 2 was associated with an increase in both indices of psychological distress and a decrease in eight facets of well-being assessed in Wave 3. Using a similar analytic approach, results from a secondary analysis indicated that higher scores on both indices of psychological distress and lower scores on seven of the well-being facets assessed in Wave 2 were associated with worse subsequent overall suffering assessed in Wave 3. These findings contribute to empirical literature on the implications of suffering for well-being.

Motivational interviewing for caries prevention in adolescents: a randomized controlled trial.

OBJECTIVE: The objective of this study is to investigate the effectiveness of motivational interviewing (MI) in changing health behaviors (snack and toothbrushing) and preventing dental caries among adolescents. METHODS: Five hundred and twelve adolescents with unfavorable caries-related behaviors ("snacking three times or more a day" and/or "toothbrushing less often than twice a day") were randomly assigned to three groups. Group I received prevailing health education (oral health talks and pamphlets). Participants in group II joined a one-on-one face-to-face MI session. In group III, a patient communication tool (Cariogram) was incorporated to facilitate the MI process. At baseline and 24 months post-intervention, a self-administered questionnaire gathered information of participants' sociodemographic characteristics and oral health self-efficacy and behaviors. Their oral hygiene and tooth status were assessed by a blinded examiner. RESULTS: After 24 months, 460 (89.8%) participants were followed up. Compared with group I, (i) restriction of frequent snacking was more likely in group II [OR (95% CI): 3.91 (1.48-10.33)] and group III [OR (95% CI): 6.33 (2.46-16.27)], whereas group III tended to adopt the behavior of toothbrushing twice a day [OR (95% CI): 4.80 (1.79-12.85)]; (ii) no significant between-group difference in plaque score reduction was found (p > 0.05); and (iii) groups II and III developed fewer cavitated teeth (△DICDASII 3-6MFT) [ß (95% CI): - 0.19 (- 0.37, - 0.01) and - 0.20 (- 0.38, - 0.02), respectively], whereas increment of total carious lesions (△DICDASII 1-6MFT) was lower in group III [ß (95% CI): - 0.63 (- 1.24, - 0.02)]. CONCLUSION: MI outperformed prevailing health education in improving oral health behaviors and preventing dental caries among adolescents. CLINICAL RELEVANCE: Incorporating MI into dental care for caries-prone adolescents contributes to optimal health outcomes.

The Chinese version of Posttraumatic Growth and Depreciation Inventory-Expanded version (PTGDI-X) for cancer survivors.

Many patients with cancer report positive changes often referred to as posttraumatic growth (PTG). Some of these self-reported PTG may represent maladaptive illusions created by individuals to cope with the illness. A recently established Posttraumatic Growth and Depreciation Inventory - Expanded version (PTGDI-X) includes both PTG and posttraumatic depreciation (PTD) items. This inventory may provide a more balanced picture of the phenomenological world of cancer survivors. We examined the Chinese version of the PTGDI-X's applicability to cancer patients, and how PTG and PTD were related to posttraumatic stress symptoms. Two hundred sixty-five cancer survivors in Taiwan completed the Chinese version of the PTGDI-X, along with the PTSD Checklist for the DSM-5 to measure posttraumatic stress disorder (PTSD) symptoms. Confirmatory factor analysis showed that the factor structure of the PTGDI-X established in a multi-national study fit our data from cancer patients modestly well. The PTD score had a significant and positive correlation with PTSD symptoms, whereas the PTG and PTSD showed a significant curvilinear relationship in the form of an inverted U-shape. This study's results indicate that PTG and PTD are separated constructs with differential relationships with cancer outcomes. The Chinese version of the PTGDI-X is a viable instrument for psycho-oncological research. The PTD scores can provide useful information to guide cognitive interventions to reduce distorted cognitions. In contrast, the PTG scores can provide further information on the phenomenological world of cancer survivors. In this study, clinical implications and future studies were considered.

Telehealth to the Rescue During COVID-19: A Convergent Mixed Methods Study Investigating Patients' Perception.

Background: The onset of the pandemic necessitated abrupt transition to telehealth consultations. Although there is a few tools that gauge the patients' perception about their experiences, none of them are contextualized to an emergency in the Middle East and North Africa region. Accordingly, this study aims at developing and validating a tool to address this gap, and deploying it to assess the patients' perception of telehealth services during COVID-19 in Dubai, United Arab Emirates (UAE). Methods: A convergent mixed methods design was adapted. A random selection of 100 patients from Dubai, UAE were invited to participate. Qualitative and quantitative datasets were collected using a tailor-made survey. The qualitative data, collected through open-ended questions, was analyzed using multi-staged thematic analysis. As for the quantitative data, it captured the patients' extent of satisfaction, and was assessed using SPSS (with a series of descriptive and inferential analyses). The qualitative and quantitative findings were then merged via joint display analysis. Results: Out of the 100 patients that were randomly selected, 94 patients participated in this study. The reliability score of Cronbach's Alpha for the instrument was 98.9%. The percentage of the total average of satisfaction was 80.67%. The Principal Component Analysis showed that 88.1% of the variance can be explained by the instrument (p < 0.001). The qualitative data analysis expanded upon the quantitative findings enabling a better understanding of the patients' perception. Three themes, revolving around the quality of the patient telehealth experiences, surfaced: "Factors that worked to the benefit of the patients," "Factors that the patients were not in favor of," and "Opportunities for improvements as perceived by the patients." Discussion: This study introduced a novel patient satisfaction with telehealth consultation survey contextualized to the COVID-19 times in Dubai, UAE. The participants were quite satisfied with the quality of their experience, however they suggested areas for improvement. Regional healthcare decision-makers can leverage the identified advantages and opportunities for improvement of telehealth. This will enable making informed decisions regarding the continuity of telehealth irrespective of how matters unfold in relation to the pandemic. It will also better prepare the healthcare sector for potential resurgence(s) of COVID-19 and/or the occurrence of other similar emergencies.

Dietary Patterns and Associated Microbiome Changes that Promote Oncogenesis.

The recent increases in cancer incidences have been linked to lifestyle changes that result in obesity and metabolic syndrome. It is now evident that these trends are associated with the profound changes that occur in the intestinal microbiome, producing altered microbial population signatures that interact, directly or indirectly, with potentially pro-carcinogenic molecular pathways of transcription, proliferation, and inflammation. The effects of the entire gut microbial population on overall health are complex, but individual bacteria are known to play important and definable roles. Recent detailed examinations of a large number of subjects show a tight correlation between habitual diets, fecal microbiome signatures, and markers of metabolic health. Diets that score higher in healthfulness or diversity such as plant-based diets, have altered ratios of specific bacteria, including an increase in short-chain fatty acid producers, which in turn have been linked to improved metabolic markers and lowered cancer risk. Contrarily, numerous studies have implicated less healthy, lower-scoring diets such as the Western diet with reduced intestinal epithelial defenses and promotion of specific bacteria that affect carcinogenic pathways. In this review, we will describe how different dietary patterns affect microbial populations in the gut and illustrate the subsequent impact of bacterial products and metabolites on molecular pathways of cancer development, both locally in the gut and systemically in distant organs.
