The educational use of social networking sites among medical and health sciences students: a cross campus interventional study.

BACKGROUND: In recent years, social networking sites (SNSs) have evolved beyond connection and networking to become a powerful instructional tool. There is still a dearth of knowledge on the professional use of SNSs for education particularly among students from diverse backgrounds. This study examined the extent and pattern of SNSs usage for education across six institutions and then conducted an interventional workshop to fortify and regulate the educational use of SNSs. METHODS: This multicenter study was done in two phases. In the first phase, an online cross-sectional survey using a validated inventory was administered to determine the prevalence, extent, and preferences of SNSs usage by undergraduate students in medicine, health sciences and dentistry across five centers. Later, the second phase of the study was undertaken in a 75-min guided live workshop about the appropriate use of SNSs in academia. Additionally, pre- and post-test surveys were conducted to assess the impact and outcome of workshop. RESULTS: Of the 1722 respondents, 1553 (90%) reported using SNSs with the frequency of once a month to three to five times per day for education and to stay in touch with others. Most students agreed with the benefits of SNSs for education mainly in terms of information gathering, networking and collaboration. Twitter, Instagram, and Pinterest were noted as the most preferred SNSs for education. Nevertheless, 63% perceived that proper instruction was required for the efficient use of SNSs. Following the guided workshop, there was a significant improvement in web technology understanding, digital professionalism, skills and knowledge on the productive use of SNSs. Students rated the efficient for conceptual learning, connection to community practice, e-portfolio, and collaborative learning as the top four major teaching and learning strategies, respectively, in the post-workshop survey. CONCLUSION: Our study demonstrates that SNSs can be used as learning tools in medical education. However, SNSs usage should be regulated and guided for a more collegial and coherent learning climate in the digital realm. We urge medical educators to integrate SNSs into their courses for a technologically advanced and impactful curriculum.

The Association Between Female Sexual Dysfunction and Sexual Dysfunction in the Male Partner: A Systematic Review and Meta-Analysis.

BACKGROUND: The field of study addressing the relationship between FSD and male sexual dysfunction (MSD) represents a pivotal worldwide health issue as interrelationship between FSD and MSD studies are still inconclusive. AIM: To review the interrelationship between FSD and MSD and to conclude whether there is a definitive risk of men developing sexual dysfunction when his partner is suffering from FSD. METHODS: The investigation was conducted following the standard practice for conducting and reporting the findings of systematic reviews and meta-analyses comprising of 4 electronic databases, that is, Embase, PsycInfo, Cochrane Library and Ovid (Medline) from inception to December 2019. Search strategies were developed based on relevant keywords with appropriate truncation and Boolean operators' approach. The quality of studies was employed using the McMaster Critical Review Form for Quantitative Studies and were assessed by independent reviewers. The levels of evidence of the included studies were also determined. OUTCOMES: MSD who had been exposed to FSD. RESULTS: From more than 8,000 studies searched, 26 studies were finally included, and most included studies have reasonable quality. Meta-analysis found a significant sexual dysfunction in men who are partnered with women with FSD. It found a consistent correlation between FDS and sexual dysfunction in men with a significant 3-fold increase in MSD who are partnered with women with FSD (odds ratio = 3.011, 95% confidence interval: 1.856-4.885, P = <.001, I² = 42.26%). Among subtypes of MSD, likelihood increased 4-fold for erectile dysfunction and that of premature ejaculation doubled. The data for several other domains on their components were mixed. CLINICAL TRANSLATION: These findings support the notion that clinicians should evaluate sexual function pertaining to both partners and encompassing several dimensions and needing an interdisciplinary approach. STRENGTH & LIMITATIONS: This review exhaustively examines data search from vast electronic databases and as the comparison of studies is extracted from English journal publications, not all regions worldwide are represented. CONCLUSION: This meta-analysis and systematic review found an association between sexual dysfunction in men partnered with women with FSD, especially in the domains of erectile and ejaculatory function.

Examination of overall treatment effect and the proportion attributable to contextual effect in osteoarthritis: meta-analysis of randomised controlled trials.

OBJECTIVE: To examine the overall treatment effect and the proportion attributable to contextual effect (PCE) in randomised controlled trials (RCTs) of diverse treatments for osteoarthritis (OA). METHODS: We searched Medline, Embase, Central, Science Citation Index, AMED and CINAHL through October 2014, supplemented with manual search of reference lists, published meta-analyses and systematic reviews. Included were RCTs in OA comparing placebo with representative complementary, pharmacological, non-pharmacological and surgical treatments. The primary outcome was pain. Secondary outcomes were function and stiffness. The effect size (ES) of overall treatment effect and the PCE were pooled using random-effects model. Subgroup analyses and meta-regression were conducted to examine determinants of the PCE. RESULTS: In total, 215 trials (41 392 participants) were included. The overall treatment effect for pain ranged from the smallest with lavage (ES=0.46, 95% CI 0.24 to 0.68) to the largest with topical non-steroidal anti-inflammatory drugs (ES=1.37, 95% CI 1.19 to 1.55). On average, 75% (PCE=0.75, 95% CI 0.72 to 0.79) of pain reduction was attributable to contextual effect. It varied by treatment from 47% (PCE=0.47, 95% CI 0.32 to 0.70) for intra-articular corticosteroid to 91% (PCE=0.91, 95% CI 0.60 to 1.37) for joint lavage. Similar results were observed for function and stiffness. Treatment delivered by needle/injection and other means than oral medication, longer duration of treatment, large sample size (≥100 per arm) and public funding source were associated with increased PCE for pain reduction. CONCLUSIONS: The majority (75%) of the overall treatment effect in OA RCTs is attributable to contextual effects rather than the specific effect of treatments. Reporting overall treatment effect and PCE, in addition to traditional ES, permits a more balanced, clinically meaningful interpretation of RCT results. This would help dispel the frequent discordance between conclusions from RCT evidence and clinical experience-the 'efficacy paradox'.

Does flare trial design affect the effect size of non-steroidal anti-inflammatory drugs in symptomatic osteoarthritis? A systematic review and meta-analysis.

OBJECTIVES: It is thought that the clinical trial benefits of oral non-steroidal anti-inflammatory drugs (NSAIDs) may relate to flare designs. The aim of this study was to examine the difference in NSAID (including cyclooxygenase-2 (COX-2) inhibitors) response in osteoarthritis (OA) trials based on different designs. METHODS: Systematic review was undertaken of the databases MEDLINE, EMBASE, AMED, CINAHL and the Cochrane library till February 2015. Randomised controlled trials assessing pain, function and/or stiffness following commencement of NSAIDs in flare and non-flare designs were eligible. Trials were assessed using the Cochrane Risk of Bias tool. Meta-analyses were conducted to assess the effect sizes (ES) of NSAIDs for OA with flare versus non-flare trial designs. RESULTS: Fifty-seven studies including 33 263 participants assessing 26 NSAIDs were included. Twenty-two (39%) were flare design, 24 (42%) were non-flare designs, 11 (19%) were possible flare designs. On meta-analysis, there was no statistically significant difference in ES of NSAIDs versus placebo between flare and non-flare trial designs for absolute pain and function or stiffness at immediate-term (1 week), short-term (2-4 week) or longer-term (12-13 week) follow-up periods (p>0.05). However there was a lower ES for mean change in pain in flare and possible flare trials compared with non-flare trials at short-term follow-up (0.36 vs 0.69; p=0.05). CONCLUSIONS: Contrary to previous understanding, flare trial designs do not result in an increased treatment effect for NSAIDs in people with OA compared with non-flare design. Whether flare design influences other outcomes such as joint effusion remains unknown.

Gut Microbiota Composition in Prediabetes and Newly Diagnosed Type 2 Diabetes: A Systematic Review of Observational Studies.

Evidence of gut microbiota involvement in regulating glucose metabolism and type 2 diabetes mellitus (T2DM) progression is accumulating. The understanding of microbial dysbiosis and specific alterations of gut microbiota composition that occur during the early stages of glucose intolerance, unperturbed by anti-diabetic medications, is especially essential. Hence, this systematic review was conducted to summarise the existing evidence related to microbiota composition and diversity in individuals with prediabetes (preDM) and individuals newly diagnosed with T2DM (newDM) in comparison to individuals with normal glucose tolerance (nonDM). A systematic search of the PubMed, MEDLINE and CINAHL databases were conducted from inception to February 2021 supplemented with manual searches of the list of references. The primary keywords of "type 2 diabetes", "prediabetes", "newly-diagnosed" and "gut microbiota" were used. Observational studies that conducted analysis of the gut microbiota of respondents with preDM and newDM were included. The quality of the studies was assessed using the modified Newcastle-Ottawa scale by independent reviewers. A total of 18 studies (5,489 participants) were included. Low gut microbial diversity was generally observed in preDM and newDM when compared to nonDM. Differences in gut microbiota composition between the disease groups and nonDM were inconsistent across the included studies. Four out of the 18 studies found increased abundance of phylum Firmicutes along with decreased abundance of Bacteroidetes in newDM. At the genus/species levels, decreased abundance of Faecalibacterium prausnitzii, Roseburia, Dialister, Flavonifractor, Alistipes, Haemophilus and Akkermansia muciniphila and increased abundance of Lactobacillus, Streptococcus, Escherichia, Veillonella and Collinsella were observed in the disease groups in at least two studies. Lactobacillus was also found to positively correlate with fasting plasma glucose (FPG), HbA1c and/or homeostatic assessment of insulin resistance (HOMA-IR) in four studies. This renders a need for further investigations on the species/strain-specific role of endogenously present Lactobacillus in glucose regulation mechanism and T2DM disease progression. Differences in dietary intake caused significant variation in specific bacterial abundances. More studies are needed to establish more consistent associations, between clinical biomarkers or dietary intake and specific gut bacterial composition in prediabetes and early T2DM.

Changing Professional Behaviors in the Digital World Using the Medical Education e-Professionalism (MEeP) Framework-A Mixed Methods Multicentre Study.

Background: There is increasing evidence on the exponential use of technology-based social media in medical field that has led to a proliferation of unprofessional behaviors in digital realm. Educating, training, and changing the behaviors of healthcare professionals are essential elements to restrain the rising unprofessional incidents. Therefore, this research was designed to determine the impact of an interventional workshop on the medical and dental students in improving their professional behaviors in the digital world using the newly developed medical Education e-Professionalism (MEeP) framework. Methods: We adopted the Theory of Planned Behavior (TPB) as a benchmark reference which explores constructs intertwined with the mission-based MEeP framework; values (whistleblowing-raising concerns), behaviors (being responsible in the digital world) and identity (reflective practice in the digital world). A multicentre 3-phased mixed-method study was conducted using a pre-workshop survey, an online interventional workshop, and a post-workshop survey. SPSS and NVivo were the tools used for the data analysis. Results: A total of 130 students registered for workshop out of which 120 completed the pre-workshop survey, 62 joined the workshop and 59 completed the workshop and post-workshop survey. From the whistleblowing - raising concern perspective, we found that attitudes and perceived behavioral control had a significant relationship. While for responsible in digital world category, attitude and perceived behavioral control had a significant bearing on the intentions. Third, for reflective practice, attitude and subjective norms significantly enhanced the intention of participants. A multi layered thematic analysis yielded four overarching themes of attitudes, subjective norms, perceived behavioral control and intentions. Most students showed positive attitudes of being reflective, self-directed, and humane. Students realized the subjective norms had made them conscientious, self-aware and conformative. While perceived behavioural control manifested as identity and Intentions were heavily reliant on self-actualization. Conclusion: Our mixed method study found that the interventional workshop using MEeP framework significantly improved attitudes, subjective norms, perceived behavioral control, and intentions. This study provides valuable evidence of MEeP framework evaluation using the theoretical underpinning of TPB by reporting positive changes in professional values, behaviors, and identities of undergraduate medical and dental students.

Proportion of contextual effects in the treatment of fibromyalgia-a meta-analysis of randomised controlled trials.

The objective of this study is to examine the proportion of the total treatment effect that is attributable to contextual effects in randomised controlled trials (RCTs) of treatments for fibromyalgia. A systematic literature search was undertaken in Medline, Web of Science, EMBASE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Allied and Complementary Medicine in September 2015. The proportion of contextual effect (PCE) was calculated by dividing the improvement in the placebo arm by the improvement in the treatment arm. The measure was log-transformed for each trial and the random effects model was used to pool data. The primary outcome was pain. Secondary outcomes were fibromyalgia impact questionnaire (FIQ) total and fatigue. Heterogeneity was quantified using I 2. Publication bias was assessed using a funnel plot and Egger's test. Subgroup analysis was undertaken to explore heterogeneity and potential determinants of the PCE. Fifty-one eligible trials (9599 participants) were identified. The PCE was 0.60 (95% CI 0·56 to 0·64) for pain, 0·57 (95% CI 0·53 to 0·61) for FIQ total, and 0·63 (95% CI 0·59 to 0·68) for fatigue. The I 2 was 99.4% for pain, 99.2% for FIQ total, and 97.6% for fatigue. More than half of the treatment effect in fibromyalgia RCTs results from non-specific contextual factors. This suggests that optimising contextual care may enhance treatment effects and improve outcomes. Reporting the total treatment effect and the proportion of contextual effect in trials may help to better translate research evidence into practice.

The placebo effect and its determinants in fibromyalgia: meta-analysis of randomised controlled trials.

The aims of this study were to determine whether placebo treatment in randomised controlled trials (RCTs) is effective for fibromyalgia and to identify possible determinants of the magnitude of any such placebo effect. A systematic literature search was undertaken for RCTs in people with fibromyalgia that included a placebo and/or a no-treatment (observation only or waiting list) control group. Placebo effect size (ES) for pain and other outcomes was measured as the improvement of each outcome from baseline divided by the standard deviation of the change from baseline. This effect was compared with changes in the no-treatment control groups. Meta-analysis was undertaken to combine data from different studies. Subgroup analysis was conducted to identify possible determinants of the placebo ES. A total of 3912 studies were identified from the literature search. After scrutiny, 229 trials met the inclusion criteria. Participants who received placebo in the RCTs experienced significantly better improvements in pain, fatigue, sleep quality, physical function, and other main outcomes than those receiving no treatment. The ES of placebo for pain relief was clinically moderate (0.53, 95%CI 0.48 to 0.57). The ES increased with increasing strength of the active treatment, increasing participant age and higher baseline pain severity, but decreased in RCTS with more women and with longer duration of fibromyalgia. In addition, placebo treatment in RCTs is effective in fibromyalgia. A number of factors (expected strength of treatment, age, gender, disease duration) appear to influence the magnitude of the placebo effect in this condition.
