P-329 Exploring the feasibility of a training program in frailty for primary healthcare providers in Greece: a study protocol
Feasibility and impact of a short training course on frailty destined for primary health care professionals
BACKGROUND: There is an unmet need for training primary health care professionals on frailty, especially in countries where geriatrics is still emerging. PURPOSE: We aimed to evaluate the feasibility and efficacy of a training course for primary health care professionals on the detection, assessment, and management of frailty. METHODS: A single-day training course, developed and facilitated by three physicians trained in geriatrics abroad, was organized by the Aristotle University of Thessaloniki Primary Hearth Care Research Network. Primary health care professionals' attitudes, knowledge, and everyday practices regarding frailty were assessed by self-administered anonymous questionnaires (using Likert-type scales) at three time-points (before, upon completion of the training course, and 3Â months afterward). RESULTS: Out of 31 participants (17 physicians, 12 nurses, 2 health visitors; 87.1% women; mean age 46.4Â years), 31(100%) filled in the first, 30(97%) the second, and 25(81%) the third questionnaire. Improvements were reported in familiarization with the frailty syndrome (pâ=â0.041) and in self-perception of knowledge and skills to detect (pâ<â0.001) and manage (pâ<â0.001) frailty, that were also sustained 3Â months afterward (pâ=â0.001 and pâ=â0.003 respectively). Improvement was also observed in the attitude that frailty is an inevitable consequence of aging (pâ=â0.007) and in the frequency of application of screening (but not management) strategies, 3Â months following the workshop compared to baseline (pâ=â0.014). Participants reported less disagreement with the statement that systematic screening for frailty was unfeasible in their daily practice at 3Â months compared to baseline (pâ=â0.006), mainly due to time restrictions. CONCLUSION: A short skill-oriented training course can significantly and sustainably improve primary health care professionals' attitudes and practices regarding frailty

Reporting of Adverse Events in Published and Unpublished Studies of Health Care Interventions : A Systematic Review
BACKGROUND: We performed a systematic review to assess whether we can quantify the underreporting of adverse events (AEs) in the published medical literature documenting the results of clinical trials as compared with other nonpublished sources, and whether we can measure the impact this underreporting has on systematic reviews of adverse events. METHODS AND FINDINGS: Studies were identified from 15 databases (including MEDLINE and Embase) and by handsearching, reference checking, internet searches, and contacting experts. The last database searches were conducted in July 2016. There were 28 methodological evaluations that met the inclusion criteria. Of these, 9 studies compared the proportion of trials reporting adverse events by publication status. The median percentage of published documents with adverse events information was 46% compared to 95% in the corresponding unpublished documents. There was a similar pattern with unmatched studies, for which 43% of published studies contained adverse events information compared to 83% of unpublished studies. A total of 11 studies compared the numbers of adverse events in matched published and unpublished documents. The percentage of adverse events that would have been missed had each analysis relied only on the published versions varied between 43% and 100%, with a median of 64%. Within these 11 studies, 24 comparisons of named adverse events such as death, suicide, or respiratory adverse events were undertaken. In 18 of the 24 comparisons, the number of named adverse events was higher in unpublished than published documents. Additionally, 2 other studies demonstrated that there are substantially more types of adverse events reported in matched unpublished than published documents. There were 20 meta-analyses that reported the odds ratios (ORs) and/or risk ratios (RRs) for adverse events with and without unpublished data. Inclusion of unpublished data increased the precision of the pooled estimates (narrower 95% confidence intervals) in 15 of the 20 pooled analyses, but did not markedly change the direction or statistical significance of the risk in most cases. The main limitations of this review are that the included case examples represent only a small number amongst thousands of meta-analyses of harms and that the included studies may suffer from publication bias, whereby substantial differences between published and unpublished data are more likely to be published. CONCLUSIONS: There is strong evidence that much of the information on adverse events remains unpublished and that the number and range of adverse events is higher in unpublished than in published versions of the same study. The inclusion of unpublished data can also reduce the imprecision of pooled effect estimates during meta-analysis of adverse events
The effectiveness of technology-supported personalised learning in low- and middle-income countries: A meta-analysis
AbstractDigital technology offers the potential to address educational challenges in resourceâpoor settings. This metaâanalysis examines the impact of students' use of technology that personalises and adapts to learning level in lowâ and middleâincome countries. Following a systematic search for research between 2007 and 2020, 16 randomised controlled trials were identified in five countries. Studies involved 53,029 learners aged 6â15 years. Coding examined learning domain (mathematics and literacy); personalisation level and delivery; technology use; and intervention duration and intensity. Overall, technologyâsupported personalised learning was found to have a statistically significantâif moderateâpositive effect size of 0.18 on learning (p = 0.001). Metaâregression reveals how more personalised approaches which adapt or adjust to learners' level led to significantly greater impact (an effect size of 0.35) than those only linking to learners' interests or providing personalised feedback, support, and/or assessment. Avenues for future research include investigating cost implications, optimum programme length, and teachers' role in making personalised learning with technology effective.
Practitioner notesWhat is already known about this topic?
Promoting personalised learning is an established aim of educators.
Using technology to support personalised learning in lowâ and middleâincome countries (LMICs) could play an important role in ensuring more inclusive and equitable access to education, particularly in the aftermath of COVIDâ19.
There is currently no rigorous overview of evidence on the effectiveness of using technology to enable personalised learning in LMICs.
What this paper adds?
The metaâanalysis is the first to evaluate the effectiveness of technologyâsupported personalised learning in improving learning outcomes for schoolâaged children in LMICs.
Technologyâsupported personalised learning has a statistically significant, positive effect on learning outcomes.
Interventions are similarly effective for mathematics and literacy and whether or not teachers also have an active role in the personalisation.
Personalised approaches that adapt or adjust to the learner led to significantly greater impact, although whether these warrant the additional investment likely necessary for implementation at scale needs to be investigated.
Personalised technology implementation of moderate duration and intensity had similar positive effects to that of stronger duration and intensity, although further research is needed to confirm this.
Implications for practice and/or policy:
The inclusion of more adaptive personalisation features in technologyâassisted learning environments can lead to greater learning gains.
Personalised technology approaches featuring moderate personalisation may also yield learning rewards.
While it is not known whether personalised technology can be scaled in a costâeffective and contextually appropriate way, there are indications that this is possible.
The appropriateness of teachers integrating personalised approaches in their practice should be explored given âsupplementaryâ uses of personalised technology (ie, additional sessions involving technology outside of regular instruction) are common.

Thalidomide in the treatment of erythema nodosum leprosum (ENL): systematic review of clinical trials and prospects of new investigations
FUNDAMENTOS: A hansenĂase persiste como problema de saĂșde pĂșblica, e episĂłdios de ENH sĂŁo eventos agudos que ocorrem antes, durante e apĂłs PQT. Na Ășltima dĂ©cada, o uso da talidomida como agente imunomodulador foi expandido a outras doenças. OBJETIVOS: realizar revisĂŁo sistemĂĄtica dos ensaios clĂnicos publicados sobre a eficĂĄcia e efeitos colaterais da talidomida no ENH. Descrever metodologia e resultados da triagem para recrutamento de ensaio clĂnico visando avaliar dose-resposta da talidomida seguida de desmame no ENH moderado e grave, realizado no Brasil. MĂTODOS: Analisaram-se ensaios publicados sobre talidomida no ENH. Foi delineado um ensaio clĂnico duplo-cego randomizado para avaliar dose de 100 thalid 300mg/dia de talidomida durante fase aguda de ENH, seguida de desmame da talidomida, thalid placebo. Para este ensaio clĂnico descreve-se metodologia e dados de recrutamento de pacientes, com ĂȘnfase na gravidade dos episĂłdios de ENH. RESULTADOS: Os seis ensaios clĂnicos publicados nas dĂ©cadas de 1960 e 1970 apontam para o benefĂcio da talidomida no ENH, embora diferenças metodolĂłgicas dificultem a comparação. Na fase de recrutamento do ensaio brasileiro, dos 143 pacientes de ENH triados, 65% eram potencialmente elegĂveis. A associação com neurite em 56,4% dos ENH moderados e graves exigiu co-intervenção com corticosterĂłide. CONCLUSĂO: O padrĂŁo de recrutamento dos pacientes evidenciou alta freqĂŒĂȘncia de neurite nos episĂłdios de ENH. O esquema de talidomida isolada no ENH foi avaliado como infreqĂŒente na prĂĄtica clĂnica brasileira. O desafio atual Ă© acumular evidĂȘncias sobre a eficĂĄcia e efeitos colaterais da talidomida em associação com corticosterĂłides.BACKGROUND: Leprosy remains a public health problem. Episodes of erythema nodosum leprosum (ENL) are acute events that occur before, during and after polychemotherapy. In the last decade, the use of thalidomide as an immunomodulating agent was expanded to other diseases. OBJECTIVES: To perform a systematic review of published clinical trials on efficacy and side effects of thalidomide in ENL. To describe the methodology and screening results of recruiting for a clinical trial performed in Brazil, which aimed to assess the dose-response of thalidomide followed by tapering regimen in severe and moderate cases of ENL. METHODS: Published clinical trials on the use of thalidomide in ENL were analyzed. A randomized, double-blind clinical trial was designed to evaluate the doses of 100mg versus 300mg/day thalidomide during the acute stage of ENL, followed by thalidomide tapering regimen versus placebo. For this clinical trial, the methodology and data for enrollment of patients were described, with an emphasis on severity of ENL episodes. RESULTS: Six clinical trials published in the 1960's and 1970's indicated the benefits of thalidomide in ENL, although methodological differences made comparison difficult. In the enrollment stage of the Brazilian trial, 65% of patients were potentially eligible out of 143 ENL patients screened. The association with neuritis in 56.4% of moderate and severe cases of ENL required the co-intervention with steroids. CONCLUSION: The patients' enrollment pattern demonstrated high frequency of neuritis in ENL episodes. The treatment regimen with thalidomide in monotherapy for ENL was considered infrequent in the clinical practice in Brazil. The current challenge is to accumulate evidence about efficacy and side effects of thalidomide in combination with steroids
Diet and risk of gastric cancer: an umbrella review
Several dietary exposures have been associated with gastric cancer (GC), but the associations are often heterogenous and may be afflicted by inherent biases. In the context of an Umbrella Review (UR), we provide an overview and a critical evaluation of the strength and quality, and evidence classification of the associations of diet-related exposures in relation to the risk of GC. We searched PubMed and Scopus for eligible meta-analyses of observational studies published in English from inception to 12 December 2021, and for any identified association, we applied robust epidemiological validity evaluation criteria and individual study quality assessment using AMSTAR. We screened 3846 titles/abstracts and assessed 501 full articles for eligibility, of which 49 were included in the analysis, investigating 147 unique exposures in relation to GC, cardia (GCC) or non-cardia (GNCC) cancer. Supported by suggestive evidence, positive associations were found comparing the highest vs. lowest categories for: heavy (>42 g/day) alcohol consumption (Relative Risk (RR) = 1.42, 95% Confidence Interval (CI): 1.20â1.67), salted fish consumption (RR = 1.56, 95% CI:1.30â1.87) and waist circumference (RR = 1.48, 95% CI:1.24â1.78) and an inverse association for the healthy lifestyle index (RR = 0.60, 95% CI:0.48â0.74) in relation to GC. Additionally, a positive association was found comparing obese individuals (Body Mass Index (BMI) â„ 30) to normal-weight individuals (BMI: 18.5â25) (RR = 1.82, 95% CI:1.32â2.49) in relation to GCC. Most of the meta-analyses were of medium-to-high quality (median items: 7.0, interquartile range: 6â9). Maintaining a normal body weight and adopting healthy dietary choices, in particular, limiting the consumption of salt-preserved foods and alcohol, can reduce the risk of gastric cancer
