Once-weekly insulin icodec versus once-daily long-acting insulins for type 2 diabetes mellitus: Systematic review and meta-analysis.

Background: Insulin icodec is a novel, long-acting, once-weekly basal insulin analog. Its comparative efficacy and safety with basal once-daily insulins in type 2 diabetes mellittus is uncertain. Objective: Evaluate potential efficacy, benefits and risks associated with icodec compared to once-daily basal insulin analogs (degludec or glargine). Methods: We systematically searched PubMed, Cochrane, and Embase for randomized controlled trials (RCTs) published until June 2023 comparing icodec versus long-acting insulin analogs (degludec and glargine) in type 2 diabetes mellitus (T2DM) with at least 12 weeks of follow-up. Binary endpoints were assessed with risk ratios (RRs) and continuous endpoints were compared using mean differences (MDs), with 95% confidence intervals (CIs). The protocol was registered in PROSPERO (CRD42023452468). Results: A total of seven RCTs and 3286 patients with T2DM were included, of whom 1509 (60.6%) received icodec treatment. The follow-up period ranged from 16 to 78 weeks. Compared with once-daily basal insulin analogs, icodec led to a greater improvement in HbA1c (MD -0.15%; 95% CI -0.21, -0.10; p < 0.0001; I2 = 0%) and time in range (TIR) (MD 2.83%; 95%CI 0.94; 4.71; p = 0.003; I2 = 22%). Body weight was increased with icodec treatment (MD 0.78 Kg; 95%CI 0.42, 1.15; p < 0.01; I2 = 86%). There was also a higher rate of injection site reactions (RR 1.89; 95%CI 1.12, 3.18; p = 0.016; I2 = 0%) and nasopharyngitis (RR 1.94; 95%CI 1.11, 3.38; p = 0.020; I2 = 0%) in the icodec group, compared with once-daily regimens. There was no significant difference between groups in fasting plasma glucose. Conclusions: In this meta-analysis of RCTs, insulin icodec led to better control of HbA1c and TIR as compared with once-daily insulin regimens, albeit with increased weight gain and a higher rate of injection site reaction in the Icodec group.

Fezolinetant for the treatment of vasomotor symptoms associated with menopause: a meta-analysis.

This systematic review and meta-analysis investigated the efficacy and safety of fezolinetant for the treatment of moderate-to-severe vasomotor symptoms (VMS) associated with menopause. PubMed, Cochrane Library, Embase and Web of Science were searched for randomized controlled trials (RCTs) published from inception to June 2023, comparing fezolinetant to placebo in postmenopausal women suffering from moderate-to-severe VMS. The mean difference and risk ratio were calculated for continuous and binary outcomes, respectively. R software was used for the statistical analysis, and RoB-2 (Cochrane) to assess the risk of bias. We performed subgroup analysis based on different dosing regimens. Five RCTs comprising 3302 patients were included. Compared with placebo, at 12-week follow-up, fezolinetant significantly reduced the daily frequency of moderate-to-severe VMS (weighted mean difference [WMD] - 2.36; 95% confidence interval [CI] - 2.92, -1.81) and daily severity of moderate-to-severe VMS (WMD -0.22; 95% CI -0.31, -0.13). Also, fezolinetant significantly improved the quality of life (WMD -0.42; 95% CI -0.58, -0.26) and sleep disturbance (WMD -1.10; 95% CI -1.96, -0.24). There were no significant differences between groups in adverse events. These findings support the efficacy and safety of fezolinetant for the treatment of VMS related to menopause.

Comorbid autoimmune disorders in people with multiple sclerosis: A retrospective cohort study.

Most autoimmune disorders, including multiple sclerosis (MS), are influenced by shared genetic and environmental factors. We conducted a cohort study of people with MS to calculate the frequency of comorbid autoimmune disorders and characterize this cohort. Autoimmune diseases were present in 30 (8.6%) of 349 patients. The most prevalent diagnoses were autoimmune thyroiditis, type 1 diabetes mellitus, psoriasis, and inflammatory bowel disease. We found no association with demographic or clinical factors. In our cohort, autoimmune disorders were not uncommon. Identifying such comorbidities in people with MS can be determinant for understanding disease mechanisms, treatment decisions and disease management.

Glucose control and psychosocial outcomes with use of automated insulin delivery for 12 to 96 weeks in type 1 diabetes: a meta-analysis of randomised controlled trials.

BACKGROUND: Glycaemic control of Type 1 Diabetes Mellitus (T1DM) remains a challenge due to hypoglycaemic episodes and the burden of insulin self-management. Advancements have been made with the development of automated insulin delivery (AID) devices, yet, previous reviews have only assessed the use of AID over days or weeks, and potential benefits with longer time of AID use in this population remain unclear. METHODS:  We performed a systematic review and meta-analysis of randomised controlled trials comparing AID (hybrid and fully closed-loop systems) to usual care (sensor augmented pumps, multiple daily insulin injections, continuous glucose monitoring and predictive low-glucose suspend) for adults and children with T1DM with a minimum duration of 3 months. We searched PubMed, Embase, Cochrane Central, and Clinicaltrials.gov for studies published up until April 4, 2023. Main outcomes included time in range 70-180 mg/dL as the primary outcome, and change in HbA1c (%, mmol/mol), glucose variability, and psychosocial impact (diabetes distress, treatment satisfaction and fear of hypoglycaemia) as secondary outcomes. Adverse events included diabetic ketoacidosis (DKA) and severe hypoglycaemia. Statistical analyses were conducted using mean differences and odds ratios. Sensitivity analyses were performed according to age, study duration and type of AID device. The protocol was registered in PROSPERO, CRD42022366710. RESULTS: We identified 25 comparisons from 22 studies (six crossover and 16 parallel designs) including a total of 2376 participants (721 in adult studies, 621 in paediatric studies, and 1034 in combined studies) which were eligible for analysis. Use of AID devices ranged from 12 to 96 weeks. Patients using AID had 10.87% higher time in range [95% CI 9.38 to 12.37; p < 0.0001, I2 = 87%) and 0.37% (4.77 mmol/mol) lower HbA1c (95% CI - 0.49% (- 6.39 mmol/mol) to - 0.26 (- 3.14 mmol/mol); p < 0·0001, I2 = 77%]. AID systems decreased night hypoglycaemia, time in hypoglycaemia and hyperglycaemia and improved patient distress, with no increase in the risk of DKA or severe hypoglycaemia. No difference was found regarding treatment satisfaction or fear of hypoglycaemia. Among children, there was no difference in glucose variability or time spent in hypoglycaemia between the use of AID systems or usual care. In sensitivity analyses, results remained consistent with the overall analysis favouring AID. CONCLUSION: The use of AID systems over 12 weeks, regardless of technical or clinical differences, improved glycaemic outcomes and diabetes distress without increasing the risk of adverse events in adults and children with T1DM.

2023 UPDATE: Luso-Brazilian evidence-based guideline for the management of antidiabetic therapy in type 2 diabetes.

BACKGROUND: The management of antidiabetic therapy in people with type 2 diabetes (T2D) has evolved beyond glycemic control. In this context, Brazil and Portugal defined a joint panel of four leading diabetes societies to update the guideline published in 2020. METHODS: The panelists searched MEDLINE (via PubMed) for the best evidence from clinical studies on treating T2D and its cardiorenal complications. The panel searched for evidence on antidiabetic therapy in people with T2D without cardiorenal disease and in patients with T2D and atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), or diabetic kidney disease (DKD). The degree of recommendation and the level of evidence were determined using predefined criteria. RESULTS AND CONCLUSIONS: All people with T2D need to have their cardiovascular (CV) risk status stratified and HbA1c, BMI, and eGFR assessed before defining therapy. An HbA1c target of less than 7% is adequate for most adults, and a more flexible target (up to 8%) should be considered in frail older people. Non-pharmacological approaches are recommended during all phases of treatment. In treatment naïve T2D individuals without cardiorenal complications, metformin is the agent of choice when HbA1c is 7.5% or below. When HbA1c is above 7.5% to 9%, starting with dual therapy is recommended, and triple therapy may be considered. When HbA1c is above 9%, starting with dual therapyt is recommended, and triple therapy should be considered. Antidiabetic drugs with proven CV benefit (AD1) are recommended to reduce CV events if the patient is at high or very high CV risk, and antidiabetic agents with proven efficacy in weight reduction should be considered when obesity is present. If HbA1c remains above target, intensification is recommended with triple, quadruple therapy, or even insulin-based therapy. In people with T2D and established ASCVD, AD1 agents (SGLT2 inhibitors or GLP-1 RA with proven CV benefit) are initially recommended to reduce CV outcomes, and metformin or a second AD1 may be necessary to improve glycemic control if HbA1c is above the target. In T2D with HF, SGLT2 inhibitors are recommended to reduce HF hospitalizations and mortality and to improve HbA1c. In patients with DKD, SGLT2 inhibitors in combination with metformin are recommended when eGFR is above 30 mL/min/1.73 m2. SGLT2 inhibitors can be continued until end-stage kidney disease.

Safety and Effectiveness of Cladribine in Multiple Sclerosis: Real-World Clinical Experience From 5 Tertiary Hospitals in Portugal.

OBJECTIVES: Cladribine is a selective and oral immunological reconstitution treatment, approved in Europe for very active multiple sclerosis (MS) with relapses. Aims were to assess the safety and effectiveness of cladribine in real-world setting, during treatment follow-up. METHODS: This was a multicentric, longitudinal, observational study with retrospective and prospective data collection of clinical, laboratory, and imaging data. This interim analysis reports data from July 1, 2018 (study onset), to March 31, 2021. RESULTS: A total of 182 patients were enrolled: 68.7% were female; mean age at onset was 30.1 ± 10.0 years, and mean age at first cycle of cladribine treatment was 41.1 ± 12.1; 88.5% were diagnosed with relapse-remitting MS and 11.5% with secondary progressive MS. Mean disease duration at cladribine start was 8.9 ± 7.7 years. Most patients (86.1%) were not naive, and median number of previous disease-modifying therapies was 2 (interquartile range, 1-3). At 12 months, we observed no significant Expanded Disability Status Scale score worsening ( P = 0.843, Mann-Whitney U test) and a significantly lower annualized relapse rate (0.9 at baseline to 0.2; 78% reduction). Cladribine treatment discontinuation was registered in 8% of patients, mainly (69.2%) due to disease activity persistence. Most frequent adverse reactions were lymphocytopenia (55%), infections (25.2%), and fatigue (10.7%). Serious adverse effects were reported in 3.3%. No patient has discontinued cladribine treatment because of adverse effects. CONCLUSION: Our study confirms the clinical efficacy and the safety profile of cladribine for treating MS patients with a long-term active disease in the real-world setting. Our data contribute to the body of knowledge of the clinical management of MS patients and the improvement of related clinical outcomes.

Consensus for the Early Identification of Secondary Progressive Multiple Sclerosis in Portugal: a Delphi Panel.

INTRODUCTION: Multiple sclerosis is a disease with a heterogeneous evolution. The early identification of secondary progressive multiple sclerosis is a clinical challenge, which would benefit from the definition of biomarkers and diagnostic tools applicable in the transition phase from relapsing-remitting multiple sclerosis to secondary progressive multiple sclerosis. We aimed to reach a Portuguese national consensus on the monitoring of patients with multiple sclerosis and on the more relevant clinical variables for the early identification of its progression. MATERIAL AND METHODS: A Delphi panel which included eleven Portuguese Neurologists participated in two rounds of questions between July and August of 2021. In the first round, 39 questions which belonged to the functional, cognitive, imaging, biomarkers and additional evaluations were included. Questions for which no consensus was obtained in the first round (less than 80% of agreement), were appraised by the panel during the second round. RESULTS: The response rate was 100% in both rounds and consensus was reached for a total of 33 questions (84.6%). Consensus was reached for monitoring time, evaluation scales and clinical variables such as the degree of brain atrophy and mobility reduction, changes suggestive of secondary progressive multiple sclerosis. Additionally, digital devices were considered tools with potential to identify disease progression. Most questions for which no consensus was obtained referred to the cognitive assessment and the remaining referred to both functional and imaging domains. CONCLUSION: Consensus was obtained for the determination of the monitorization interval and for most of the clinical variables. Most questions that did not reach consensus were related with the confirmation of progression taking into account only one test/domain, reinforcing the multifactorial nature of multiple sclerosis.

The 2021-2022 position of Brazilian Diabetes Society on diabetic kidney disease (DKD) management: an evidence-based guideline to clinical practice. Screening and treatment of hyperglycemia, arterial hypertension, and dyslipidemia in the patient with DKD.

BACKGROUND: Diabetic kidney disease is the leading cause of end-stage renal disease and is associated with increased morbidity and mortality. This review is an authorized literal translation of part of the Brazilian Diabetes Society (SBD) Guidelines 2021-2022. This evidence-based guideline provides guidance on the correct management of Diabetic Kidney Disease (DKD) in clinical practice. METHODS: The methodology was published elsewhere in previous SBD guidelines and was approved by the internal institutional Steering Committee for publication. Briefly, the Brazilian Diabetes Society indicated 14 experts to constitute the Central Committee, designed to regulate methodology, review the manuscripts, and make judgments on degrees of recommendations and levels of evidence. SBD Renal Disease Department drafted the manuscript selecting key clinical questions to make a narrative review using MEDLINE via PubMed, with the best evidence available including high-quality clinical trials, metanalysis, and large observational studies related to DKD diagnosis and treatment, by using the MeSH terms [diabetes], [type 2 diabetes], [type 1 diabetes] and [chronic kidney disease]. RESULTS: The extensive review of the literature made by the 14 members of the Central Committee defined 24 recommendations. Three levels of evidence were considered: A. Data from more than 1 randomized clinical trial or 1 metanalysis of randomized clinical trials with low heterogeneity (I2 < 40%). B. Data from metanalysis, including large observational studies, a single randomized clinical trial, or a pre-specified subgroup analysis. C: Data from small or non-randomized studies, exploratory analyses, or consensus of expert opinion. The degree of recommendation was obtained based on a poll sent to the panelists, using the following criteria: Grade I: when more than 90% of agreement; Grade IIa 75-89% of agreement; IIb 50-74% of agreement, and III, when most of the panelist recommends against a defined treatment. CONCLUSIONS: To prevent or at least postpone the advanced stages of DKD with the associated cardiovascular complications, intensive glycemic and blood pressure control are required, as well as the use of renin-angiotensin-aldosterone system blocker agents such as ARB, ACEI, and MRA. Recently, SGLT2 inhibitors and GLP1 receptor agonists have been added to the therapeutic arsenal, with well-proven benefits regarding kidney protection and patients' survival.

Virtual Reality-Induced Dissociative Symptoms: A Retrospective Study.

Objective: The use of virtual reality (VR) has been increasing worldwide, as devices are becoming more sophisticated and provide an escape from reality during the COVID-19 lockdown. This recent rise in the use of VR leads to new side effects being reported, such as dissociative symptoms that may or may not constitute a mental health concern. This retrospective study investigated the prevalence and intensity of dissociative symptoms in VR users, as well as some potential predisposing conditions that may trigger them, and their impact on the subjects' wellbeing. Materials and Methods: We conducted a survey (n = 358) that was posted on VR Facebook groups. This survey was approved by the University of Lisbon Medical Faculty's IRB, and comprised a modified version of the Clinician-Administered Dissociative State Scale (CADSS) and questions regarding potential risk factors known to induce dissociative disorders or experiences. Results: Data analysis revealed that 83.9% participants reported dissociative symptoms, with varying intensity according to CADSS (X̄=7.62;s=7.89). Significant correlations were found between CADSS score and the time spent playing, the use of software applications (apps) that involve virtual hands or hand tracking, history of previous dissociative experiences, traumatic childhood events, avoidant coping strategies, and psychiatric disorders. Nonetheless, most participants categorized the symptoms as nonanxiogenic (85.8%) and minute lasting (77.4%). Conclusion: In conclusion, this study revealed that although VR can induce dissociative experiences, they seem to be short lasting and nonthreatening to the individual's wellbeing and might be predicted or attenuated by managing other known risk factors for dissociative phenomena.

Late onset neuromyelitis optica spectrum disorders (LONMOSD) from a nationwide Portuguese study: Anti-AQP4 positive, anti-MOG positive and seronegative subgroups.

INTRODUCTION: Several neuroimmunological disorders have distinct phenotypes according to the age of onset, as in multiple sclerosis or myasthenia gravis. It is also described that late onset NMOSD (LONMOSD) has a different phenotype. OBJECTIVE: To describe the clinical/demographic characteristics of the LONMOSD and distinguish them from those with early onset (EONMOSD). METHODS: From a nationwide Portuguese NMOSD study we analyzed the clinical/demographic characteristics of the LONMOSD. RESULTS: From the 180 Portuguese patients 45 had disease onset after 50 years old, 80% were female. 23 had anti-AQP4 antibodies (51.1%), 13 anti-MOG antibodies (28.9%) and 9 were double seronegative (20.0%). The most common presenting phenotypes in LONMOSD were transverse myelitis (53.3%) and optic neuritis (26.7%), without difference from EONMOSD (p = 0.074). The mean EDSS for LONMOSD was 6.0 (SD=2.8), after a mean follow-up time of 4.58 (SD=4.47) years, which was significantly greater than the mean EDSS of EONMOSD (3.25, SD=1.80)(p = 0.022). Anti-AQP4 antibodies positive LONMOSD patients had increased disability compared to anti-MOG antibodies positive LONMOSD (p = 0.022). The survival analysis showed a reduced time to use a cane for LONMOSD, irrespective of serostatus (p<0.001). CONCLUSIONS: LONMOSD has increased disability and faster progression, despite no differences in the presenting clinical phenotype were seen in our cohort.

Parents' cardiovascular risk factors are related to overweight and obesity in young Brazilians with type 1 diabetes.

AIM: To identify family background characteristics and cardiovascular disease (CVD) risk factors linked to overweight and obesity in Brazilian with type 1 diabetes (T1D). METHODS: We performed cross-sectional anthropometric and laboratory analyses in young individuals with T1D. RESULTS: Among 181 participants, 87 were women and 94 were men (64%/78% normal weight, 27%/15% overweight and 9%/7% obese). Obese men were older; were more likely to be Black; had higher triglyceride levels and diastolic blood pressure (BP), lower estimated glucose disposal rate (eGDR) and higher prevalence of first-degree relatives (FDR) with hypertension and early CVD. Overweight and obese women were more likely to have lower eGDR, and obese women were more likely to have FDR with obesity. CONCLUSION: One third of young people with T1D were overweight or obese. Excess weight was associated with family history (FH) of obesity for women and FH of early CVD or hypertension for men. BMI was related to decreased insulin sensitivity in both genders, but only men with T1D had metabolic impairment. Our data highlight the importance of considering family background in individuals with T1D.

[Development and Implementation of a Patient Registry: The Experience of a Multiple Sclerosis Center in Portugal]. / Desenvolvimento e Implementação de um Registo de Doentes: Experiência de um Centro de Esclerose Múltipla em Portugal.

INTRODUCTION: Patient registries allow better evaluations of therapeutic outcomes and support personalized health care in several conditions. This study aimed to implement a local registry in a multiple sclerosis center in Portugal, in order to carry out a critical analysis of its development stages, and to perform an initial analysis of the included patients. MATERIAL AND METHODS: The establishment of the registry was divided in two phases - development (creation of the online platform for data entry) and implementation (recruitment of patients and retrospective and prospective collection of available information). A demographic and clinical analysis of patients was performed. RESULTS: Neurologists and study coordinators participated in the project, accounting for a total of 1050 hours of work in the implementation phase. Amongst the 498 multiple sclerosis patients included, 72.9% were female and relapsing-remitting multiple sclerosis was the most common subtype of the disease. The most frequently prescribed drugs at diagnosis were beta interferons. Missing data in electronic health records were detected concerning the progression of disability and diagnostic tests. DISCUSSION: The difficulties encountered could be mitigated by defining minimum elements to be included in patient records and by implementing more minimalist registries. This could reduce the time spent by healthcare professionals in collecting information, thus optimizing costs, and allowing the focus to be placed on personalized healthcare by taking advantage of the registry and its associated tools. CONCLUSION: Despite the amount of data collected within the scope of this study, several difficulties affected the implementation and maintenance of the registry, which could be overcome by improving future strategies.

Introdução: Registos de doentes permitem avaliar melhor resultados terapêuticos e suportar a personalização de cuidados de saúde em diversas patologias. Este trabalho teve como objetivos: implementar um registo local num centro de esclerose múltipla em Portugal; proceder a uma análise crítica das suas etapas de desenvolvimento; e realizar uma primeira análise dos doentes incluídos.Material e Métodos: A criação do registo dividiu-se em duas fases: desenvolvimento (construção da plataforma online) e implementação (recrutamento de doentes e recolha retrospetiva e prospetiva da informação disponível). Realizou-se uma análise demográfica e clínica dos doentes incluídos.Resultados: Especialistas em Neurologia e coordenadores de estudo participaram no projeto, num total de 1050 horas de trabalho na fase de implementação. Dos 498 doentes com esclerose múltipla incluídos no estudo, 72,9% eram do género feminino, tendo sido identificada como subtipo de doença mais comum a esclerose múltipla surto remissão. Os fármacos mais frequentemente prescritos após diagnóstico foram interferões beta. Detetaram-se lacunas no processo clínico dos doentes relativamente à progressão da incapacidade e a exames complementares de diagnóstico.Discussão: As dificuldades encontradas poderão ser mitigadas através da definição de elementos obrigatórios nos processos clínicos dos doentes e da implementação de registos mais minimalistas. Este procedimento possibilitaria reduzir o tempo despendido por profissionais de saúde na recolha de informação, otimizar custos, e permitir o foco na utilização do registo e ferramentas associadas ao mesmo para personalização de cuidados de saúde.Conclusão: Apesar do volume de dados recolhidos no âmbito deste estudo, foram encontradas dificuldades que comprometeram a implementação e manutenção do registo, que poderão ser ultrapassadas com a otimização de estratégias futuras.

Neuromyelitis optica spectrum disorders: A nationwide Portuguese clinical epidemiological study.

INTRODUCTION: Neuromyelitis optica spectrum disorder (NMOSD) is a rare disorder in which astrocyte damage and/or demyelination often cause severe neurological deficits. OBJECTIVE: To identify Portuguese patients with NMOSD and assess their epidemiological/clinical characteristics. METHODS: This was a nationwide multicenter study. Twenty-four Portuguese adult and 3 neuropediatric centers following NMOSD patients were included. RESULTS: A total of 180 patients met the 2015 Wingerchuk NMOSD criteria, 77 were AQP4-antibody positive (Abs+), 67 MOG-Abs+, and 36 seronegative. Point prevalence on December 31, 2018 was 1.71/100,000 for NMOSD, 0.71/100,000 for AQP4-Abs+, 0.65/100,000 for MOG-Abs+, and 0.35/100,000 for seronegative NMOSD. A total of 44 new NMOSD cases were identified during the two-year study period (11 AQP4-Abs+, 27 MOG-Abs+, and 6 seronegative). The annual incidence rate in that period was 0.21/100,000 person-years for NMOSD, 0.05/100,000 for AQP4-Abs+, 0.13/100,000 for MOG-Abs+, and 0.03/100,000 for seronegative NMOSD. AQP4-Abs+ predominated in females and was associated with autoimmune disorders. Frequently presented with myelitis. Area postrema syndrome was exclusive of this subtype, and associated with higher morbidity/mortality than other forms of NMOSD. MOG-Ab+ more often presented with optic neuritis, required less immunosuppression, and had better outcome. CONCLUSION: Epidemiological/clinical NMOSD profiles in the Portuguese population are similar to other European countries.

Defining the prodromal phase of multiple sclerosis based on healthcare access in a Portuguese population - ProdMS study.

BACKGROUND: Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system. Prodromal symptoms and higher healthcare use have been suggested in patients who later develop MS. OBJECTIVES: Assess the healthcare utilization pattern of relapsing-remitting MS (RRMS) patients in the five years prior to MS diagnosis. METHODS: Retrospective, multicentric study. Demographic and clinical data, drug prescriptions and diagnostic tests were collected from electronic health records five-years previous to MS diagnosis and compared with national data. RESULTS: Included 168 patients, 112 (66.7%) female, median age 34±11 years. The mean number of healthcare use per patient per year was 3.14±2,69, most of them in primary healthcare (47%). Most frequent symptoms were musculoskeletal (22%), gastrointestinal (17%), sensitive (14%) and sensory organs (14%). Median number of diagnostic tests per patient was 6 (IQR 7), and drug prescriptions per patient was 6 (IQR 9). Most frequently prescribed drugs were analgesic/anti-inflammatories, antibiotics and anxiolytics and there was a high request rate of MRIs. CONCLUSION: RRMS patients had a high frequency of healthcare utilization when compared to national data. This supports the current evidence showing a prodromal phase in MS.

Development and validation of a pocket guide for the prevention of diabetic foot ulcers.

OBJECTIVE: Diabetic foot ulcers can have serious consequences, including amputation. This project aimed to develop and validate a diabetes care management model-a pocket guide on the prevention of foot ulceration to assist health professionals and scientific societies. METHODS: An adaptation of the Iowa method of evidence-based practice to promote high-quality care was employed. After problems are identified, the Iowa method supports the development of an action plan for addressing them. An evidence-based protocol based on the five cornerstones of the 2015 guidance on the diabetic foot by the International Working Group on the Diabetic Foot was developed in two phases and validated using the Delphi technique. RESULTS: A model was developed to promote these five cornerstones, which are the main recommendations for managing the diabetic foot. These are: foot examination; risk assessment for ulceration; education in diabetes; appropriate footwear; and treatment of pre-ulcerative lesions. To adapt this into a health information document, the management model was synthesised and designed as a pocket guide. The model's individual and global content validity indices surpass 0.78 and 0.90 respectively. CONCLUSION: A management model was created and validated, and produced as a pocket guide to deliver instructions on the care and prevention of diabetic foot problems in people with diabetes.

Multiple Sclerosis Patient Management During the COVID-19 Pandemic: Practical Recommendations From the Portuguese Multiple Sclerosis Study Group (GEEM).

The spread of the COVID-19 pandemic has imposed significant challenges on healthcare provision, requiring changes in the conventional patient management, particularly in chronic diseases like multiple sclerosis (MS). To increase patient safety and reduce the risk of infection, while ensuring an appropriate and regular follow-up, tele-medicine gained prominence as a valid alternative to face-to-face appointments. However, the urgency of the implementation and the lack of experience in most MS centers led to "ad hoc" and extremely diverse approaches, which now merit to be standardized and refined. Indeed, while tele-consultation cannot fully replace face-to-face visits, it certainly can, and will, be incorporated as part of the routine care of MS patients in the near future. Bearing this in mind, the Portuguese Multiple Sclerosis Study Group (GEEM) has developed a set of recommendations for the usage of tele-medicine in the management of MS patients, both during the pandemic and in the future. The consensus was obtained through a two-step modified Delphi methodology, resulting in 15 recommendations, which are detailed in the manuscript.

The first series of cases of ketosis-prone type 2 diabetes (flatbush diabetes) in Brazilian adults.

Ketosis-prone type 2 diabetes (KPD) is an emerging form of diabetes mellitus characterized by unprovoked ketoacidosis, absence of autoimmunity and beta-cell dysfunction. The KPD may improve after initial glycemic compensation and evolve to exogenous insulin independence, most cases were observed in populations with African or Hispanic backgrounds. We reviewed the literature on KPD and, to date, only one case of KPD has been described in Brazil's multi-ethnic population. A group of adult Brazilian KPD patients without autoimmunity and insulinopenia was identified for this study. We report a retrospective study of four KPD cases (3 males) evaluated in southeast Brazil, the patients were overweight or obese, age between the third and fifth decades of life, had a family history of type 2 diabetes, hyperglycemia (809.5 ± 344.2 mg/dL), acidosis (pH 7.21 ± 0.07; normal range (nr): 7.35-7.45 and bicarbonate 9.1 ± 6.2; nr: 22-26 mEq/mL), ketonuria (142.5 ± 114.4 mg/dL; nr: absence), absence of glutamic acid decarboxylase antibodies (GAD-65), and beta-cell function reserve (C-peptide 1.19 ± 0.53 ng/mL - nr: 1.1-4.4 ng/mL) on diagnosis. After glycemic compensation, there was increase of C-peptide (2.21 ± 0.41) indicating the recovery of beta-cell function and the time to insulin independence was 7.7 ± 3.5 months. They evolved after the period of glucotoxicity with insulin withdrawal and could be treated with oral antidiabetic therapy. This is the first case series of KPD described in Brazil being characterized by ketoacidosis at diagnosis, absence of autoimmunity, recovery of beta-cell function and insulin independence.

TyPed study: Natalizumab for the treatment of pediatric-onset multiple sclerosis in Portugal.

BACKGROUND: A significant proportion of pediatric-onset multiple sclerosis (POMS) patients do not respond to first-line disease-modifying therapies. Clinical trials showed that natalizumab is effective and safe in adults, but there are limited clinical trial data for children. Natalizumab is currently prescribed off-label for POMS. We aimed to characterize the effectiveness, safety and tolerability of natalizumab in all POMS cases treated in Portugal (from 2007 to 2018). METHODS: Data from clinical records were retrospectively collected for all POMS cases treated with natalizumab in Portugal. RESULTS: Twenty-one patients were included, 14 (67%) of which were female. The median age at POMS diagnosis was 13 years old. The median duration of treatment with natalizumab was 2 years and 3 months. Median Expanded Disability Status Scale score decreased from 1.5 to 1.0 after 24 months. The Annualized Relapse Rate decreased from 1.31 events/patient/year before treatment with natalizumab to 0 after 12 months of treatment and to 0.04 after 24 months. No gadolinium-enhancing lesions or new or enlarged T2 hyperintense lesions were observed in 8/8 patients (100%) after 12 months, and 4/5 (80%) after 24 months. There was one possible serious adverse event, which did not require dose adjustment. Five patients discontinued treatment due to positive anti-JCV (JC virus) antibody JC serostatus. CONCLUSION: Natalizumab may be an effective and safe disease-modifying therapy for POMS. Our results are in line with data published for the adult population, as well as with similar observational studies in pediatric populations in other regions.

RISCOP-Cognitive profile in a Portuguese cohort of radiological isolated syndrome patients: A case-control study.

INTRODUCTION: Radiologically isolated syndrome (RIS) refers to the incidental discovery of white matter lesions suggestive of MS, on brain MRI, in asymptomatic patients. Recent studies suggest similar features of cognitive impairment between RIS and MS patients. Also, lower levels of health-related quality of life (QOL) and fatigue are reported in such patients. AIMS: characterize and compare the cognitive profile of a multicentric Portuguese cohort of RIS patients with a control group. METHODS: multicentric comparative study of a cohort of adult patients with RIS, and age and gender-matched controls followed in the headache outpatient clinic with prior MRI not fulfilling criteria for RIS diagnosis. We conducted interviews with participants, collected clinical data and applied the BICAMS battery and self-reported questionnaires (HADS, MFIS, MSQOL-54). RESULTS: we evaluated 31 patients with RIS (median age 46 years, IQR [(Dusankova et al., 2012-52], 72% women) and 19 control individuals (median age 32 years, IQR [(O'Jile et al., 2005-48], 71% women). Prevalence of cognitive impairment did not differ between groups (16% of the RIS and 10% of the controls, p=0.579). We found no differences between groups on the BICAMS tests, although the results of the California Verbal Learning Test (CVLT-II) score presented a trend to significance, with a lower value on the RIS group (53.9 vs. 59.3, p=0.066). There were no significant differences regarding fatigue, QOL, anxiety/depression scores. CONCLUSION: this is the first study on a Portuguese cohort of RIS patients assessing cognitive profile with BICAMS. A non-neglectable part of our cohort presented cognitive impairment. Our findings add to previous studies in suggesting that a more pronounced impairment of verbal memory and learning, evaluated by CVLT-II, may be present in RIS patients compared to controls. BICAMS should be assessed on future studies with larger cohorts.

[Recommendations about Multiple Sclerosis Management during Pregnancy, Partum and Post-Partum: Consensus Position of the Portuguese Multiple Sclerosis Study Group]. / Recomendações sobre a Abordagem da Esclerose Múltipla na Gravidez, Parto e Pós-Parto: Posição de Consenso do Grupo de Estudos de Esclerose Múltipla.

Multiple sclerosis typically affects young women of reproductive age. Therefore, all healthcare professionals involved in the follow-up of multiple sclerosis patients must be prepared to discuss pregnancy and breastfeeding issues and provide the best possible counselling. However, there are still many doubts and heterogeneous clinical approaches partly due to the lack of consensus and guidelines. Concerning the handling of disease modifying therapies during pregnancy and postpartum, existing uncertainties have been complicated by the increase in the number of treatments available in recent years. This article aims to present the state-of-the-art and provide guidance based on the best level of available evidence and expert opinion regarding the management of multiple sclerosis patients at different stages: pregnancy planning, pregnancy, partum, and the postpartum period.

A esclerose múltipla afecta tipicamente mulheres jovens em idade reprodutiva. Desta forma, todo os profissionais de saúde envolvidos no seguimento destes doentes deverão estar preparados para abordar as questões relacionadas com a gravidez e amamentação e fornecer o melhor aconselhamento possível. No entanto, existem ainda muitas dúvidas e abordagens clínicas heterogéneas em parte devido à ausência de consensos e normas orientadoras. No que concerne ao manuseamento das terapêuticas modificadoras de doença durante os períodos de gravidez e pós-parto, as incertezas têm sido agravadas devido ao aumento do número de fármacos disponíveis nos últimos anos. Este artigo visa apresentar a informação mais atual e fornecer orientações baseadas no melhor nível de evidência disponível e na opinião de peritos relativamente ao seguimento das doentes com esclerose múltipla em diferentes etapas: planificação da gravidez, gravidez, parto e período pós-parto.
