RESUMEN
Few diseases globally require treatment from so many different disciplines as diabetes-related foot disease. At least 25 different professionals may be involved: casting technicians, dermatologists, diabetes (educator) nurses, diabetologists, dieticians, endocrinologists, general practitioners, human movement scientists, infectious diseases experts, microbiologists, nuclear medicine physicians, orthopaedic surgeons, orthotists, pedorthists, physical therapists, plastic surgeons, podiatric surgeons, podiatrists, prosthetists, psychologists, radiologists, social workers, tissue viability physicians, vascular surgeons, and wound care nurses. A shared vocabulary and shared treatment goals and recommendations are then essential. The International Working Group on the Diabetic Foot (IWGDF) has produced guidelines and supporting documents to stimulate and support shared and multidisciplinary evidence-based treatment in diabetes-related foot disease. In this special virtual issue of Diabetes/Metabolism Research and Reviews, all 21 documents of the 2023 update of the IWGDF Guidelines are bundled, added with a further 6 reviews from multidisciplinary experts to drive future research and clinical innovations, based on their contributions to the International Symposium on the Diabetic Foot. We hope the readers will enjoy this special virtual issue, and widely implement the knowledge shared here in their daily clinical practice and research endeavours with the goal to improve the care for people with diabetes-related foot disease.

INTRODUCTION: In this podcast, we present the result of the 2023 scheduled update of the 2019 guidelines of the International Working Group of the Diabetic Foot (IWGDF) addressing the use of systems to classify foot ulcers in people with diabetes in routine clinical practice. METHODS: These guidelines were based on a systematic review of the available literature that identified 28 classifications addressed in 149 articles and, subsequently, expert opinion using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. We first assessed the value of each system independently and, in the second stage, chose the best one or two to be used in each clinical scenario. RESULTS: We recommend (1) for communication among healthcare professionals to use the Site, Ischaemia, Neuropathy, Bacterial infection, Area, Depth (SINBAD) classification (first option) or consider using Wound, Ischaemia, foot Infection (WIfI) system (alternative option, when the required equipment and level of expertise are available and it is considered feasible) and in each case the individual variables that compose the systems should be described rather than a total score; (2) for predicting the outcome of an ulcer in a specific individual: no existing system could be recommended; (3) for characterising a person with an infected ulcer: the use of the IDSA (Infection Diseases Society of America)/IWGDF (first option) classification or consider using the WIfI system (alternative option, when the required equipment and level of expertise are available and it is considered as feasible); (4) for characterising a person with peripheral artery disease: consider using the WIfI system as a means to stratify healing likelihood and amputation risk; (5) for the audit of outcome(s) of populations: the use of the SINBAD score. CONCLUSION: Although there is no classification that fits all purposes, it is crucial that healthcare professionals standardize the way they characterise diabetes-related foot ulcers and guide their decision-making process by using validated classification systems.
RESUMEN
Observational, cross-sectional prevalence studies are costly and time-consuming. The development of indirect methods estimating prevalence used to obtain faster, less-expensive, and more robust results would be an advantage for several healthcare applications. This study aimed to use the drug dispensing data from community pharmacies to estimate the prevalence of Type 2 Diabetes mellitus (T2DM) in the Portuguese population. A cross-sectional study was conducted using a database of dispensed medicines with an indication for Diabetes mellitus in 2018 and 2021, stratified by geographic region. The methodology was based on a sequential method of acquiring prevalence estimates obtained through exposure to medicines using the daily doses defined per thousand inhabitants per day and adjusted to the rate of adherence to therapy, prescription patterns, and concomitance of antidiabetic drugs. The estimated overall T2DM prevalence in 2018 was 13.9%, and it was 14.2% for 2021. The results show the increased consumption of antidiabetic drugs, with fixed-dose combination antidiabetics and new antidiabetics being particularly important in 2021. This work allowed for the development of a model to obtain the estimated prevalence of T2DM based on drug consumption, using a simple, fast, and robust method that is in line with the available evidence. However, with the recent expanding indications for new antidiabetics, the inclusion of further data in the model needs to be studied.
RESUMEN
AIMS: Diabetes-related foot disease is a major source of patient burden and societal costs. Investing in evidence-based international guidelines on diabetes-related foot disease is important to reduce this burden and costs, provided the guidelines are focused on outcomes important to key stakeholders and are evidence-based and properly implemented. MATERIALS AND METHODS: The International Working Group on the Diabetic Foot (IWGDF) has published and updated international guidelines since 1999. The 2023 updates were made using the Grading of Recommendations Assessment Development and Evaluation evidence-to-decision framework. This concerns formulating relevant clinical questions and important outcomes, conducting systematic reviews of the literature and meta-analyses where appropriate, completing summary of judgement tables, and writing recommendations that are specific, unambiguous and actionable, along with their transparent rationale. RESULTS: We herein describe the development of the 2023 IWGDF Guidelines on the prevention and management of diabetes-related foot disease, which consists of seven chapters, each prepared by a separate working group of international experts. These chapters provide guidelines related to diabetes-related foot disease on prevention; classification of diabetes-related foot ulcer, offloading, peripheral artery disease, infection, wound healing interventions, and active Charcot neuro-osteoarthropathy. Based on these seven guidelines, the IWGDF Editorial Board also produced a set of practical guidelines. Each guideline underwent extensive review by the members of the IWGDF Editorial Board as well as independent international experts in each field. CONCLUSIONS: We believe that the adoption and implementation of the 2023 IWGDF guidelines by healthcare providers, public health agencies, and policymakers will improve the prevention and management of diabetes-related foot disease, and subsequently reduce the worldwide patient and societal burden caused by this disease.

BACKGROUND: This publication represents a scheduled update of the 2019 guidelines of the International Working Group of the Diabetic Foot (IWGDF) addressing the use of systems to classify foot ulcers in people with diabetes in routine clinical practice. The guidelines are based on a systematic review of the available literature that identified 28 classifications addressed in 149 articles and, subsequently, expert opinion using the GRADE methodology. METHODS: First, we have developed a list of classification systems considered as being potentially adequate for use in a clinical setting, through the summary of judgements for diagnostic tests, focussing on the usability, accuracy and reliability of each system to predict ulcer-related complications as well as use of resources. Second, we have determined, following group debate and consensus, which of them should be used in specific clinical scenarios. Following this process, in a person with diabetes and a foot ulcer we recommend: (a) for communication among healthcare professionals: to use the SINBAD (Site, Ischaemia, Bacterial infection, Area and Depth) system (first option) or consider using WIfI (Wound, Ischaemia, foot Infection) system (alternative option, when the required equipment and level of expertise is available and it is considered feasible) and in each case the individual variables that compose the systems should be described rather than a total score; (b) for predicting the outcome of an ulcer in a specific individual: no existing system could be recommended; (c) for characterising a person with an infected ulcer: the use of the IDSA/IWGDF classification (first option) or consider using the WIfI system (alternative option, when the required equipment and level of expertise is available and it is considered as feasible); (d) for characterising a person with peripheral artery disease: consider using the WIfI system as a means to stratify healing likelihood and amputation risk; (e) for the audit of outcome(s) of populations: the use of the SINBAD score. CONCLUSIONS: For all recommendations made using GRADE, the certainty of evidence was judged, at best, as being low. Nevertheless, based on the rational application of current data this approach allowed the proposal of recommendations, which are likely to have clinical utility.

Foot disease is a devastating complication of diabetes. For almost 3 decades, the mission of the International Working Group on the Diabetic Foot (IWGDF) is to produce evidence-based guidelines to inform health care providers worldwide on strategies for the prevention and management of diabetes-related foot disease. In this publication, we aim to better inform the reader about 'the story behind' the IWGDF Guidelines and thus facilitate improved uptake of the recommendations described in the guidelines. The first IWGDF Guidelines were published in 1999, and these have been successfully updated every 4 years since. With each update, IWGDF has improved the methodological rigour and extended the topics covered. This has been possible thanks to the involvement of > 100 experts from > 60 countries, all voluntarily dedicating their time. We estimate that the 2023 update of the IWGDF Guidelines required a total 10 years of full-time work, which would have cost 2 million euros if the voluntary work had been financially compensated. The IWGDF Guidelines are not only published in English but also translated to support local implementation. Currently available translations serve 2.9 billion people globally in their native language. As an independent and multidisciplinary organisation, IWGDF hopes that the 2023 update will continue to stimulate clinicians from all different disciplines to deliver the best care possible for these patients, will motivate researchers to undertake the high-quality trials needed to deliver the new evidence to advance the field further, and collectively will support people with diabetes-related foot disease to minimize their disease burdens.
RESUMEN
AIMS: This is the 2023 International Working Group on the Diabetic Foot guideline on the prevention of foot ulcers in persons with diabetes, which updates the 2019 guideline. This guideline is targeted at clinicians and other healthcare professionals. MATERIALS AND METHODS: We followed the Grading of Recommendations, Assessment, Development and Evaluations methodology to devise clinical questions and critically important outcomes in the PICO format, to conduct a systematic review of the medical-scientific literature including, where appropriate, meta-analyses, and to write recommendations and their rationale. The recommendations are based on the quality of evidence found in the systematic review, expert opinion where (sufficient) evidence was not available, and a weighing of the desirable and undesirable effects of an intervention, as well as patient preferences, costs, equity, feasibility and applicability. RESULTS: We recommend screening a person with diabetes at very low risk of foot ulceration annually for the loss of protective sensation and peripheral artery disease, and screening persons at higher risk at higher frequencies for additional risk factors. For preventing a foot ulcer, educate persons at-risk about appropriate foot self-care, educate not to walk without suitable foot protection, and treat any pre-ulcerative lesion on the foot. Educate moderate-to-high risk people with diabetes to wear properly fitting, accommodative, therapeutic footwear, and consider coaching them to monitor foot skin temperature. Prescribe therapeutic footwear that has a demonstrated plantar pressure relieving effect during walking, to help prevent plantar foot ulcer recurrence. Consider advising people at low-to-moderate risk to undertake a, preferably supervised, foot-ankle exercise programme to reduce ulcer risk factors, and consider communicating that a total increase in weight-bearing activity of 1000 steps/day is likely safe with regards to risk of ulceration. In people with non-rigid hammertoe with pre-ulcerative lesion, consider flexor tendon tenotomy. We suggest not to use a nerve decompression procedure to help prevent foot ulcers. Provide integrated foot care for moderate-to-high-risk people with diabetes to help prevent (recurrence of) ulceration. CONCLUSIONS: These recommendations should help healthcare professionals to provide better care for persons with diabetes at risk of foot ulceration, to increase the number of ulcer-free days and reduce the patient and healthcare burden of diabetes-related foot disease.

AIMS: Prevention of foot ulcers in persons with diabetes is important to help reduce the substantial burden on both individual and health resources. A comprehensive analysis of reported interventions is needed to better inform healthcare professionals about effective prevention. The aim of this systematic review and meta-analysis is to assess the effectiveness of interventions to prevent foot ulcers in persons with diabetes who are at risk thereof. MATERIALS AND METHODS: We searched the available scientific literature in PubMed, EMBASE, CINAHL, Cochrane databases and trial registries for original research studies on preventative interventions. Both controlled and non-controlled studies were eligible for selection. Two independent reviewers assessed risk of bias of controlled studies and extracted data. A meta-analysis (using Mantel-Haenszel's statistical method and random effect models) was done when >1 RCT was available that met our criteria. Evidence statements, including the certainty of evidence, were formulated according to GRADE. RESULTS: From the 19,349 records screened, 40 controlled studies (of which 33 were Randomised Controlled Trials [RCTs]) and 103 non-controlled studies were included. We found moderate certainty evidence that temperature monitoring (5 RCTs; risk ratio [RR]: 0.51; 95% CI: 0.31-0.84) and pressure-optimised therapeutic footwear or insoles (2 RCTs; RR: 0.62; 95% CI: 0.26-1.47) likely reduce the risk of plantar foot ulcer recurrence in people with diabetes at high risk. Further, we found low certainty evidence that structured education (5 RCTs; RR: 0.66; 95% CI: 0.37-1.19), therapeutic footwear (3 RCTs; RR: 0.53; 95% CI: 0.24-1.17), flexor tenotomy (1 RCT, 7 non-controlled studies, no meta-analysis), and integrated care (3 RCTs; RR: 0.78; 95% CI: 0.58-1.06) may reduce the risk of foot ulceration in people with diabetes at risk for foot ulceration. CONCLUSIONS: Various interventions for persons with diabetes at risk for foot ulceration with evidence of effectiveness are available, including temperature monitoring (pressure-optimised) therapeutic footwear, structured education, flexor tenotomy, and integrated foot care. With hardly any new intervention studies published in recent years, more effort to produce high-quality RCTs is urgently needed to further improve the evidence base. This is especially relevant for educational and psychological interventions, for integrated care approaches for persons at high risk of ulceration, and for interventions specifically targeting persons at low-to-moderate risk of ulceration.

Diabetes-related foot disease results in a major global burden for patients and the healthcare system. The International Working Group on the Diabetic Foot (IWGDF) has been producing evidence-based guidelines on the prevention and management of diabetes-related foot disease since 1999. In 2023, all IWGDF Guidelines have been updated based on systematic reviews of the literature and formulation of recommendations by multidisciplinary experts from all over the world. In addition, a new guideline on acute Charcot neuro-osteoarthropathy was created. In this document, the IWGDF Practical Guidelines, we describe the basic principles of prevention, classification and management of diabetes-related foot disease based on the seven IWGDF Guidelines. We also describe the organisational levels to successfully prevent and treat diabetes-related foot disease according to these principles and provide addenda to assist with foot screening. The information in these practical guidelines is aimed at the global community of healthcare professionals who are involved in the care of persons with diabetes. Many studies around the world support our belief that implementing these prevention and management principles is associated with a decrease in the frequency of diabetes-related lower-extremity amputations. The burden of foot disease and amputations is increasing at a rapid rate, and comparatively more so in middle to lower income countries. These guidelines also assist in defining standards of prevention and care in these countries. In conclusion, we hope that these updated practical guidelines continue to serve as a reference document to aid healthcare providers in reducing the global burden of diabetes-related foot disease.

Multiple disciplines are involved in the management of diabetes-related foot disease and a common vocabulary is essential for clear communication. Based on the systematic reviews of the literature that form the basis of the International Working Group on the Diabetic Foot (IWGDF) Guidelines, the IWGDF has developed a set of definitions and criteria for diabetes-related foot disease. This document describes the 2023 update of these definitions and criteria. We suggest these definitions be used consistently in both clinical practice and research, to facilitate clear communication with people with diabetes-related foot disease and between professionals around the world.

BACKGROUND: Classification and scoring systems can help both clinical management and audit the outcomes of routine care. AIM: This study aimed to assess published systems used to characterise ulcers in people with diabetes to determine which should be recommended to (a) aid communication between health professionals, (b) predict clinical outcome of individual ulcers, (c) characterise people with infection and/or peripheral arterial disease, and (d) audit to compare outcomes in different populations. This systematic review is part of the process of developing the 2023 guidelines to classify foot ulcers from the International Working Group on Diabetic Foot. METHODS: We searched PubMed, Scopus and Web of Science for articles published up to December 2021 which evaluated the association, accuracy or reliability of systems used to classify ulcers in people with diabetes. Published classifications had to have been validated in populations of >80% of people with diabetes and a foot ulcer. RESULTS: We found 28 systems addressed in 149 studies. Overall, the certainty of the evidence for each classification was low or very low, with 19 (68%) of the classifications being assessed by ≤ 3 studies. The most frequently validated system was the one from Meggitt-Wagner, but the articles validating this system focused mainly on the association between the different grades and amputation. Clinical outcomes were not standardized but included ulcer-free survival, ulcer healing, hospitalisation, limb amputation, mortality, and cost. CONCLUSION: Despite the limitations, this systematic review provided sufficient evidence to support recommendations on the use of six particular systems in specific clinical scenarios.

BACKGROUND: Most interventions to prevent foot ulcers in people with diabetes do not seek to reverse the foot abnormalities that led to the ulcer. Foot-ankle exercise programs target these clinical and biomechanical factors, such as protective sensation and mechanical stress. Multiple RCTs exist investigating the effectiveness of such programs, but these have never been summarised in a systematic review and meta-analysis. METHODS: We searched the available scientific literature in PubMed, EMBASE, CINAHL, Cochrane databases and trial registries for original research studies on foot-ankle exercise programs for people with diabetes at risk of foot ulceration. Both controlled and non-controlled studies were eligible for selection. Two independent reviewers assessed the risk of bias of controlled studies and extracted data. Meta-analysis (using Mantel-Haenszel's statistical method and random effect models) was performed when >2 RCTs were available that met our criteria. Evidence statements, including the certainty of evidence, were formulated according to GRADE. RESULTS: We included a total of 29 studies, of which 16 were RCTs. A foot-ankle exercise programme of 8-12 weeks duration for people at risk of foot ulceration results in: (a) no increase or decrease risk of foot ulceration or pre-ulcerative lesion (Risk Ratio (RR): 0.56 (95% CI: 0.20-1.57)); (b) no increase or decrease risk of adverse events (RR: 1.04 (95% CI: 0.65-1.67)); (c) not increase or decrease barefoot peak plantar pressure during walking (Mean Difference (MD): -6.28 kPa (95% CI: -69.90-57.34)); (d) no increase or decrease health-related quality of life (no meta-analysis possible). Likely results in increases in ankle joint and first metatarsalphalangeal joint range of motion (MD: 1.49° (95% CI: -0.28-3.26)) may result in improvements in neuropathy signs and symptoms (MD: -1.42 (95% CI: -2.95-0.12)), may result in a small increase in daily steps in some people (MD: 131 steps (95% CI: -492-754)), and may not increase or decrease foot and ankle muscle strength and function (no meta-analysis was possible). CONCLUSIONS: In people at risk of foot ulceration, a foot-ankle exercise programme of 8-12 weeks duration may not prevent or cause diabetes-related foot ulceration. However, such a programme likely improves the ankle joint and first metatarsalphalangeal joint range of motion and neuropathy signs and symptoms. Further research is needed to strengthen the evidence base, and should also focus on the effects of specific components of foot-ankle exercise programs.

INTRODUCTION: Hypertension is the major cause of cardiovascular disease and mortality in the world. Blood pressure control (BPC) is recognised as a key measure in the management of hypertension. Several studies have been conducted assessing the impact of specific web-based interventions in improving BPC. Our systematic review intends to identify all the available web-based interventions and determine if and which are more effective than usual care in improving BPC. METHODS AND ANALYSIS: We will include randomised control trials completed until April 2023 including patients diagnosed with hypertension comparing the effect of receiving usual care versus web-based interventions in BPC. No language restriction will be applied. We will start with an extensive electronic database search, in the Cochrane Central Register of Controlled Trials, PubMed, Embase, Scopus, EU Clinical Trials Register, Pan-African Clinical Trials Registry and ClinicalTrials.gov. Eligibility criteria will be applied blindly and independently by two researchers to the title and abstract of the references, in the first stage, and to the full version of the ones selected. All divergences will be solved by a third researcher. We will conduct a narrative description and meta-analysis (if adequate) of the results of the included studies, structured according to the type of intervention, characteristics of the population and outcome measurement. We will extract features of the web-based interventions, selecting the ones with the best outcomes regarding BPC, to later propose an ideal web-based intervention to improve BPC in hypertensive patients and/or guide future research on this topic. The risk of bias will be assessed using Cochrane's RoB2 Tool. ETHICS AND DISSEMINATION: Ethical approval is not required since this is a protocol for a systematic review. The findings of this study will be disseminated through peer-reviewed publications and national or international conference presentations. Updates of the review will be conducted, as necessary. PROSPERO REGISTRATION NUMBER: PROSPERO CRD42020184166.

BACKGROUND: Arts-based pedagogical tools have been increasingly incorporated into medical education. Visual Thinking Strategies (VTS) is a research-based, constructivist teaching methodology that aims to improve visual literacy, critical thinking, and communication skills through the process of investigating works of art. Harvard Medical School pioneered the application of VTS within medical education in 2004. While there are several studies investigating the use of VTS, there is a need to systematically assess the different programs that exist for medical education and their efficacy in improving relevant clinical skills. This systematic review aims to critically analyse the available evidence of the effectiveness of VTS in medical education to guide future research and provide a framework to adapt medical curricula. METHODS: A systematic search of PubMed, PsycINFO, and Cochrane CENTRAL databases (through November 2022) was conducted to identify studies of VTS-based interventions in undergraduate and postgraduate medical education. Two reviewers independently screened citations for inclusion criteria, extracted data, and assessed risk of bias. The extracted data was then narratively synthesized. RESULTS: Of 5759 unique citations, 10 studies met the inclusion criteria. After reference review, one additional study was included. Therefore, 11 studies were included in our review. Of these, eight reported VTS-based interventions for undergraduate medical students and three reported interventions in residency training, specifically in dermatology and ophthalmology. The main goal of most studies was to increase observational or visual diagnostic skills. Three of the studies in undergraduate medical education and two in postgraduate achieved a statistically significant improvement in observational skills in post-course evaluations. Some studies reported increased tolerance for ambiguity and empathy. CONCLUSIONS: Although the studies varied considerably in study design, learning objectives, and outcomes, findings consistently indicate that the VTS approach can serve as a vehicle to develop crucial clinical competencies, encouraging more in-depth visual analysis that could be applied when observing a patient. Despite some limitations of the included studies (lack of control groups, self-selection bias, or non-standard outcome measures), the results of this review provide support for greater inclusion of VTS training in the medical curriculum.

BACKGROUND: Older patients are more likely to have medication-related problems, which are associated with changes in pharmacokinetics and pharmacodynamics, multimorbidity, and polypharmacy. Polypharmacy and inappropriate prescribing are well-known risk factors which commonly cause adverse clinical outcomes in older people. Prescribers struggle to identify potentially inappropriate medications and to choose an adequate tapering approach. METHODS/DESIGN: The goal of the study is to translate and culturally adapt MedStopper®, an original English language web-based decision aid system in deprescribing medication, to the Portuguese population. A translation-back translation method, with validation of the obtained Portuguese version of MedStopper® will be used, followed by a comprehension test. DISCUSSION: This is the first research in the Portuguese primary care setting that aims to provide a useful online tool for the appropriate prescription of older patients. The translated version in Portuguese version of the MedStopper® tool will represent an advance that seeks to continue improving the management of medications in the elderly. The adaptation into Portuguese of the educational tool provides clinicians with a screening tool to detect potentially inappropriate prescribing in patients older than 65 that reliable and easier to use. TRIAL REGISTRATION: Retrospectively registered.

OBJECTIVE: To evaluate whether critical SARS-CoV-2 infection is more frequently associated with signs of corticospinal tract dysfunction and other neurological signs, symptoms, and syndromes, than other infectious pathogens. METHODS: This was a prospective cohort study with consecutive inclusion of patients admitted to intensive care units due to primary infectious acute respiratory distress syndrome requiring invasive mechanical ventilation > 48 hours. Eligible patients were randomly assigned to three investigators for clinical evaluation, which encompassed the examination of signs of corticospinal tract dysfunction. Clinical data, including other neurological complications and possible predictors, were independently obtained from clinical records. RESULTS: We consecutively included 54 patients with acute respiratory distress syndrome, 27 due to SARS-CoV-2 and 27 due to other infectious pathogens. The groups were comparable in most characteristics. COVID-19 patients presented a significantly higher risk of neurological complications (RR = 1.98; 95%CI 1.23 - 3.26). Signs of corticospinal tract dysfunction tended to be more prevalent in COVID-19 patients (RR = 1.62; 95%CI 0.72 - 3.44). CONCLUSION: Our study is the first comparative analysis between SARS-CoV-2 and other infectious pathogens, in an intensive care unit setting, assessing neurological dysfunction. We report a significantly higher risk of neurological dysfunction among COVID-19 patients. As such, we suggest systematic screening for neurological complications in severe COVID-19 patients.
OBJETIVO: Avaliar se a infecção grave pelo SARS-CoV-2 está mais comumente associada a sinais de disfunção do trato corticoespinhal e outros sinais, sintomas e síndromes neurológicas, em comparação com outros agentes infecciosos. MÉTODOS: Este foi um estudo de coorte prospectivo com inclusão consecutiva de doentes admitidos a unidades de cuidados intensivos devido a síndrome do desconforto respiratório agudo infeccioso primário, com necessidade de ventilação mecânica invasiva por > 48 horas. Os doentes incluídos foram atribuídos aleatoriamente a três investigadores para a avaliação clínica, a qual incluía a pesquisa de sinais de disfunção do trato corticoespinhal. Os dados clínicos, incluindo outras complicações neurológicas e possíveis preditores, foram obtidos independentemente a partir dos registros clínicos. RESULTADOS: Foram incluídos consecutivamente 54 doentes com síndrome do desconforto respiratório agudo, 27 devido a SARS-CoV-2 e 27 devido a outros agentes infecciosos. Os grupos eram comparáveis na maioria das características. Os doentes com COVID-19 apresentavam risco significativamente superior de complicações neurológicas (RR = 1,98; IC95% 1,23 - 3,26). Os sinais de disfunção do trato corticoespinhal tendiam a ser mais prevalentes em doentes com COVID-19 (RR = 1,62; IC95% 0,72 - 3,44). CONCLUSÃO: Este estudo foi a primeira análise comparativa visando avaliar disfunção neurológica, entre doentes com infecção SARS-CoV-2 e outros agentes infecciosos, em um contexto de unidade de cuidados intensivos. Reportamos um risco significativamente superior de disfunção neurológica em doentes com COVID-19. Como tal, sugere-se o rastreio sistemático de complicações neurológicas em doentes com COVID-19 crítico.

Aims: Diabetic foot ulcers (DFUs) have a significant impact on a patient's quality of life and life expectancy, with mortality rates comparable with malignant diseases. However, there is a lack of data regarding palliative care needs in this population. We aimed to characterize palliative care needs in people under diabetic foot surveillance using the Integrated Palliative care Outcome Scale (IPOS) and EuroQol-5D three-level version (EQ-5D-3L) and to assess differences between those with and without a DFU. Methods: We conducted a cross-sectional study with consecutive sampling inclusion of patients followed in a tertiary hospital's Diabetic Foot Clinic between February and October 2019 with (n = 20) and without (n = 42) active DFU. Results: The most frequent symptoms encountered were pain, weakness or lack of energy, sore or dry mouth and drowsiness. Patients with an active DFU were significantly more likely to report feeling anxious or worried in comparison with those without (95% versus 55%, p = 0.002). Only 10% of the participants with an active DFU said that they were always able to share how they felt with family and friends as much as they wanted in comparison with 45% of those without (p = 0.006). Conclusion: Our study identified palliative care needs in patients under diabetic foot surveillance with and without DFU, including a significant presence of physical symptoms. Patients in both groups showed signs of emotional/psychological distress, with a higher manifestation in patients with DFU. To the best of our knowledge, this is the first study addressing and characterizing palliative care needs in this population.
RESUMEN
Background: Renal replacement therapy (RRT) is essential in the presence of life-threatening complications associated with acute kidney injury (AKI). In the absence of urgent indications, the optimal timing for RRT initiation is still under debate. This meta-analysis aims to compare the benefits between early and late RRT initiation strategies in critically ill patients with AKI. Methods: Studies were obtained from three databases [Medical Literature Analysis and Retrieval System Online (MEDLINE), Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus], searched from inception to May 2021. The selected primary outcome was 28-day mortality. Secondary outcomes included overall mortality, recovery of renal function (RRF) and RRT-associated adverse events. A random-effects model was used for summary measures. Heterogeneity was assessed through Cochrane I 2 test statistics. Potential sources of heterogeneity for the primary outcome were sought using sensitivity analyses. Further subgroup analyses were conducted based on RRT modality and study population. Results: A total of 13 randomized controlled trials including 5193 participants were analysed. No significant differences were found between early and late RRT initiation regarding 28-day mortality [risk ratio (RR) 1.00; 95% confidence interval (CI) 0.89-1.12, I² = 30%], overall mortality (RR 1.00; 95% CI 0.90-1.12, I² = 42%) and RRF (RR 1.02; 95% CI 0.92-1.13, I² = 53%). However, early RRT initiation was associated with a significantly higher incidence of hypotensive (RR 1.34; 95% CI 1.17-1.53, I² = 6%) and infectious events (RR 1.83; 95% CI 1.11-3.02, I² = 0%). Conclusions: Early RRT initiation does not improve the 28-day and overall mortality, nor the likelihood of RRF, and increases the risk for RRT-associated adverse events, namely hypotension and infection.
RESUMEN
BACKGROUND: American Academy of Sleep Medicine guidelines suggest that clinical prediction algorithms can be used to screen patients with obstructive sleep apnea (OSA) without replacing polysomnography, the gold standard. OBJECTIVE: We aimed to identify, gather, and analyze existing machine learning approaches that are being used for disease screening in adult patients with suspected OSA. METHODS: We searched the MEDLINE, Scopus, and ISI Web of Knowledge databases to evaluate the validity of different machine learning techniques, with polysomnography as the gold standard outcome measure and used the Prediction Model Risk of Bias Assessment Tool (Kleijnen Systematic Reviews Ltd) to assess risk of bias and applicability of each included study. RESULTS: Our search retrieved 5479 articles, of which 63 (1.15%) articles were included. We found 23 studies performing diagnostic model development alone, 26 with added internal validation, and 14 applying the clinical prediction algorithm to an independent sample (although not all reporting the most common discrimination metrics, sensitivity or specificity). Logistic regression was applied in 35 studies, linear regression in 16, support vector machine in 9, neural networks in 8, decision trees in 6, and Bayesian networks in 4. Random forest, discriminant analysis, classification and regression tree, and nomogram were each performed in 2 studies, whereas Pearson correlation, adaptive neuro-fuzzy inference system, artificial immune recognition system, genetic algorithm, supersparse linear integer models, and k-nearest neighbors algorithm were each performed in 1 study. The best area under the receiver operating curve was 0.98 (0.96-0.99) for age, waist circumference, Epworth Somnolence Scale score, and oxygen saturation as predictors in a logistic regression. CONCLUSIONS: Although high values were obtained, they still lacked external validation results in large cohorts and a standard OSA criteria definition.

RESUMO Objetivo: Avaliar se a infecção grave pelo SARS-CoV-2 está mais comumente associada a sinais de disfunção do trato corticoespinhal e outros sinais, sintomas e síndromes neurológicas, em comparação com outros agentes infecciosos. Métodos: Este foi um estudo de coorte prospectivo com inclusão consecutiva de doentes admitidos a unidades de cuidados intensivos devido a síndrome do desconforto respiratório agudo infeccioso primário, com necessidade de ventilação mecânica invasiva por > 48 horas. Os doentes incluídos foram atribuídos aleatoriamente a três investigadores para a avaliação clínica, a qual incluía a pesquisa de sinais de disfunção do trato corticoespinhal. Os dados clínicos, incluindo outras complicações neurológicas e possíveis preditores, foram obtidos independentemente a partir dos registros clínicos. Resultados: Foram incluídos consecutivamente 54 doentes com síndrome do desconforto respiratório agudo, 27 devido a SARS-CoV-2 e 27 devido a outros agentes infecciosos. Os grupos eram comparáveis na maioria das características. Os doentes com COVID-19 apresentavam risco significativamente superior de complicações neurológicas (RR = 1,98; IC95% 1,23 - 3,26). Os sinais de disfunção do trato corticoespinhal tendiam a ser mais prevalentes em doentes com COVID-19 (RR = 1,62; IC95% 0,72 - 3,44). Conclusão: Este estudo foi a primeira análise comparativa visando avaliar disfunção neurológica, entre doentes com infecção SARS-CoV-2 e outros agentes infecciosos, em um contexto de unidade de cuidados intensivos. Reportamos um risco significativamente superior de disfunção neurológica em doentes com COVID-19. Como tal, sugere-se o rastreio sistemático de complicações neurológicas em doentes com COVID-19 crítico.
ABSTRACT Objective: To evaluate whether critical SARS-CoV-2 infection is more frequently associated with signs of corticospinal tract dysfunction and other neurological signs, symptoms, and syndromes, than other infectious pathogens. Methods: This was a prospective cohort study with consecutive inclusion of patients admitted to intensive care units due to primary infectious acute respiratory distress syndrome requiring invasive mechanical ventilation > 48 hours. Eligible patients were randomly assigned to three investigators for clinical evaluation, which encompassed the examination of signs of corticospinal tract dysfunction. Clinical data, including other neurological complications and possible predictors, were independently obtained from clinical records. Results: We consecutively included 54 patients with acute respiratory distress syndrome, 27 due to SARS-CoV-2 and 27 due to other infectious pathogens. The groups were comparable in most characteristics. COVID-19 patients presented a significantly higher risk of neurological complications (RR = 1.98; 95%CI 1.23 - 3.26). Signs of corticospinal tract dysfunction tended to be more prevalent in COVID-19 patients (RR = 1.62; 95%CI 0.72 - 3.44). Conclusion: Our study is the first comparative analysis between SARS-CoV-2 and other infectious pathogens, in an intensive care unit setting, assessing neurological dysfunction. We report a significantly higher risk of neurological dysfunction among COVID-19 patients. As such, we suggest systematic screening for neurological complications in severe COVID-19 patients.
