RESUMO
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.

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.
RESUMO
AIM: This study aimed to determine whether the insulin resistance (IR) and lipid profiles in Type 1 Diabetes (T1D) offspring are associated with IR and other cardiovascular risk factors in their parents. METHODS: This study included 99 T1D patients (19.6 ± 4.0 yrs.), 85 mothers and 60 fathers. Parents' IR was assessed by HOMA-IR, and the insulin sensitivity in T1D patients was assessed by the estimated Glucose Disposal Rate (eGDR). RESULTS: The eGDR in the T1D offspring was negatively related to age (p = 0.023), weight (p = 0.004), LDL (p = 0.026), and microalbuminuria (p = 0.019). Maternal Type 2 Diabetes (p < 0.001) and HOMA-IR (p = 0.029) were negatively related to eGDR in their T1D offspring. The maternal HOMA-IR and the proband's eGDR were positively (p = 0.012) and negatively (p = 0.042) associated with the birth weight of the T1D offspring, respectively. We didn't find an association with the fathers' profiles. CONCLUSIONS: In a cohort of offspring with T1D the insulin sensitivity was related to the IR, lipid profile, and the presence of T2D only in their mothers. Precocious screening and treatment of these risk factors beyond glycemic control will benefit T1D with this background.

The parameters evaluated in this study did not allow establishing a cause and effect relationship.
RESUMO
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.
RESUMO
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.

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.

AIMS: To investigate the relationship of unawareness of hypoglycemia with spectral analysis of heart rate variability (HRV) and clinical variables in type 1 diabetes (T1D) individuals. METHODS: Participants with type 1 diabetes mellitus (type 1 diabetes) were prospectively assessed for hypoglycemia awareness using the Pedersen-Bjergaard method and were classified as normal hypoglycemia awareness, impaired hypoglycemia awareness and hypoglycemia unawareness. Indices of HRV in frequency domain were evaluated and Ewing tests were used for the diagnosis of cardiovascular autonomic neuropathy (CAN). RESULTS: Ninety-eight participants with T1D (mean age 26â¯years, average diabetes duration 13â¯years, and mean HbA1c 8.4%) were included in this study. The prevalence of hypoglycemia unawareness was 28%. No significant difference was observed on the prevalence of CAN among groups of different hypoglycemia awareness (pâ¯=â¯0.740). On regression analyses, abnormal results of HRV in frequency domain were not associated with unawareness of hypoglycemia. On univariable regression analysis, age, diabetes duration and estimated creatinine clearance were associated with unawareness of hypoglycemia. CONCLUSION: CAN as assessed by Ewing tests and spectral analysis of HRV is not associated with unawareness of hypoglycemia. There is association of age, diabetes duration and renal deficit with unawareness of hypoglycemia.

Modifiable and nonmodifiable risk factors for developing posttransplant diabetes mellitus (PTDM) have already been established in kidney transplant setting and impact adversely both patient and allograft survival. We analysed 450 recipients of living and deceased donor kidney transplants using current immunosuppressive regimen in the modern era and verified PTDM prevalence and risk factors over three-year posttransplant. Tacrolimus (85%), prednisone (100%), and mycophenolate (53%) were the main immunosuppressive regimen. Sixty-one recipients (13.5%) developed PTDM and remained in this condition throughout the study, whereas 74 (16.5%) recipients developed altered fasting glucose over time. Univariate analyses demonstrated that recipient age (46.2 ± 1.3vs. 40.7 ± 0.6 years old, OR 1.04; P = 0.001) and pretransplant hyperglycaemia and BMI ≥ 25 kg/m2 (32.8% vs. 21.6%, OR 0.54; P = 0.032 and 57.4% vs. 27.7%, OR 3.5; P < 0.0001, respectively) were the pretransplant variables associated with PTDM. Posttransplant transient hyperglycaemia (86.8%. 18.5%, OR 0.03; P = 0.0001), acute rejection (P = 0.021), calcium channel blockers (P = 0.014), TG/HDL (triglyceride/high-density lipoprotein cholesterol) ratio ≥ 3.5 at 1 year (P = 0.01) and at 3 years (P = 0.0001), and tacrolimus trough levels at months 1, 3, and 6 were equally predictors of PTDM. In multivariate analyses, pretransplant hyperglycaemia (P = 0.035), pretransplant BMI ≥ 25 kg/m2 (P = 0.0001), posttransplant transient hyperglycaemia (P = 0.0001), and TG/HDL ratio ≥ 3.5 at 3-year posttransplant (P = 0.003) were associated with PTDM diagnosis and maintenance over time. Early identification of risk factors associated with increased insulin resistance and decreased insulin secretion, such as pretransplant hyperglycaemia and overweight, posttransplant transient hyperglycaemia, tacrolimus trough levels, and TG/HDL ratio may be useful for risk stratification of patients to determine appropriate strategies to reduce PTDM.

Resumo Fundamentação: desde o primeiro posicionamento da Sociedade Brasileira de Diabetes (SBD) sobre diabetes e prevenção cardiovascular, em 2014,1 importantes estudos têm sido publicados na área de prevenção cardiovascular e tratamento do diabetes,2 os quais contribuíram para a evolução na prevenção primária e secundária nos pacientes com diabetes. Ferramentas de estratificação de risco mais precisas, novos fármacos hipolipemiantes e novos antidiabéticos com efeitos cardiovasculares e redução da mortalidade, são parte desta nova abordagem para os pacientes com diabetes. O reconhecimento de que o diabetes é uma doença heterogênea foi fundamental, sendo claramente demonstrado que nem todos os pacientes diabéticos pertencem a categorias de risco alto ou muito alto. Um porcentual elevado é composto por pacientes jovens, sem os fatores de risco clássicos, os quais podem ser classificados adequadamente em categorias de risco intermediário ou mesmo em baixo risco cardiovascular. O presente posicionamento revisa as melhores evidências atualmente disponíveis e propõe uma abordagem prática, baseada em risco, para o tratamento de pacientes com diabetes. Estruturação: perante este desafio e reconhecendo a natureza multifacetada da doença, a SBD uniu-se à Sociedade Brasileira de Cardiologia (SBC) e à Sociedade Brasileira de Endocrinologia e Metabolismo (SBEM), e formou um painel de especialistas, constituído por 28 cardiologistas e endocrinologistas, para revisar as melhores evidências disponíveis e elaborar uma diretriz contendo recomendações práticas para a estratificação de risco e prevenção da Doença Cardiovascular (DVC) no Diabetes Melito (DM). As principais inovações incluem: (1) considerações do impacto de novos hipolipemiantes e das novas medicações antidiabéticas no risco cardiovascular; (2) uma abordagem prática, baseada em fator de risco, para orientar o uso das estatinas, incluindo novas definições das metas da Lipoproteína de Baixa Densidade-colesterol (LDL-colesterol) e colesterol não Lipoproteína de Alta Densidade HDL; (3) uma abordagem baseada em evidências, para avaliar a isquemia miocárdica silenciosa (IMS) e a aterosclerose subclínica em pacientes com diabetes; (4) as abordagens mais atuais para o tratamento da hipertensão; e (5) recomendação de atualizações para o uso de terapia antiplaquetária. Esperamos que esta diretriz auxilie os médicos no cuidado dedicado aos pacientes com diabetes. Métodos: inicialmente, os membros do painel foram divididos em sete subcomitês para definirem os tópicos principais que necessitavam de uma posição atualizada das sociedades. Os membros do painel pesquisaram e buscaram no PubMed estudos clínicos randomizados e metanálises de estudos clínicos e estudos observacionais de boa qualidade, publicados entre 1997 e 2017, usando termos MeSH: [diabetes], [diabetes tipo 2], [doença cardiovascular], [estratificação de risco cardiovascular] [doença arterial coronária], [rastreamento], [isquemia silenciosa], [estatinas], [hipertensão], [ácido acetilsalicílico]. Estudos observacionais de baixa qualidade, metanálises com alta heterogeneidade e estudos transversais não foram incluídos, embora talvez tenham impactado no Nível de Evidência indicado. A opinião de especialistas foi usada quando os resultados das buscas não eram satisfatórios para um item específico. É importante salientar que este posicionamento não teve a intenção de incluir uma revisão sistemática rigorosa. Um manuscrito preliminar, destacando recomendações de graus e níveis de evidência (Quadro 1), foi esboçado. Este passo levou a várias discussões entre os membros dos subcomitês, que revisaram os achados e fizeram novas sugestões. O manuscrito foi, então, revisto pelo autor líder, encarregado da padronização do texto e da inclusão de pequenas alterações, sendo submetido à apreciação mais detalhada pelos membros dos comitês, buscando uma posição de consenso. Depois desta fase, o manuscrito foi enviado para a banca editorial e edição final, sendo encaminhado para publicação. Quadro 1 Graus de recomendações e níveis de evidências adotados nesta revisão Grau de recomendação Classe I A evidência é conclusiva ou, se não, existe consenso de que o procedimento ou tratamento é seguro e eficaz Classe II Há evidências contraditórias ou opiniões divergentes sobre segurança, eficácia, ou utilidade do tratamento ou procedimento Classe IIa As opiniões são favoráveis ao tratamento ou procedimento. A maioria dos especialistas aprova Classe IIb A eficácia é bem menos estabelecida, e as opiniões são divergentes Classe III Há evidências ou consenso de que o tratamento ou procedimento não é útil, eficaz, ou pode ser prejudicial Níveis de Evidência A Múltiplos estudos clínicos randomizados concordantes e bem elaborados ou metanálises robustas de estudos clínicos randomizados B Dados de metanálises menos robustas, um único estudo clínico randomizado ou estudos observacionais C Opinião dos especialistas

BACKGROUND: Painful diabetic neuropathy (PDN) is a serious, polymorphic, and prevalent complication of diabetes mellitus. Most PDN treatment guidelines recommend a selection of drugs based on patient comorbidities. Despite the large numbers of medications available, most randomized clinical trials (RCTs) conducted so far have yielded unsatisfactory outcomes. Therefore, treatment may require a personalized approach based on pain phenotype or comorbidities. METHODS: To evaluate whether or not a patient's pain phenotype or comorbidities can influence the response to a specific PDN treatment, we conducted a systematic review using two different approaches: pain phenotype and associated comorbidities-based treatment. RESULTS: Out of 45 identified papers, 7 were thoroughly reviewed. We found four RCTs stratified according to pain phenotype with three main results: (1) paroxysmal pain had a better response to pregabalin; (2) the preservation of thermal sensation or nociception anticipated a positive response to the topical treatment of pain; and, (3) after a failure to duloxetine (60 mg/day), the patients with evoked pain or severe deep pain had a better response to association of duloxetine/pregabalin while those with paresthesia/dysesthesia benefited from duloxetine monotherapy (120 mg/day). By contrast, the other three papers provided weak and even contradictory evidence about PDN treatment based on comorbidities. CONCLUSION: Although more studies are needed to provide an adequate recommendation for clinical practice, our systematic review has provided some evidence that PDN phenotyping may optimize clinical outcomes and could, in the future, lead to both less empirical medicine and more personalized pain therapeutics.
RESUMO
BACKGROUND: Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. MAIN BODY: The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. CONCLUSIONS: Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in individuals in the highest risk as well as protection from overtreatment in those at lower risk. Thus, cardiovascular prevention strategies should be individualized according to cardiovascular risk while intensification of treatment should focus on those at higher risk.

Knowledge about association between sleep apnea and cardiovascular autonomic neuropathy (CAN) in type 1 diabetes mellitus (T1DM) might give some insight into the pathogenesis of this condition in these patients. In obese patients, excessive central adiposity, including a large neck circumference, can contribute to obstructive sleep apnea (OSA). Its presence in non-obese patients, however, indicates that it could be correlated with autonomic neuropathy. The aim of this study was to compare the prevalence of OSA in young and lean T1DM patients with and without CAN. We studied 20 adult, non-obese, T1DM patients who were divided into two groups according to the results of the cardiovascular autonomic reflex tests (CARTs). These two groups (9 with CAN and 11 without CAN) were compared to a control group of 22 healthy individuals, who were matched by age and BMI. A polysomnography was performed and sleep was analyzed. The CAN+ group had a significantly higher prevalence of sleep apnea compared to the other groups (67% CAN+; 23% CAN-; 4.5% controls: CAN+ vs. Control; p = 0.006 and CAN+ vs. CAN-; p = 0.02). The CAN- group had higher sleep efficiency compared to the CAN+ group, demonstrating impaired sleep architecture in diabetics with this chronic complication. In conclusion, OSA may be related to the presence of CAN in young and lean T1DM patients. It could contribute to worse the prognosis and reducing the quality of life of these patients without specific treatment of these conditions.
RESUMO
O diabetes mellitus tipo 2 (DM2) apresenta alta prevalência, com aumento inclusive em crianças e adolescentes. A importância de um estrito controle glicêmico pode ser comprovada com a redução das complicações crônicas microvasculares.

INTRODUCTION: Poor vascular access due to previous surgery can be a major obstacle in pancreas transplantation for which new exocrine and vascular outflow techniques might be useful. A 34-year-old female with early onset type 1 diabetes who underwent living donor kidney transplantation 20 years ago and a failed pancreas transplantation 2 years ago presented for pancreas retransplantation. METHODS: The inferior vena cava was used in the previous deceased donor pancreas transplantation and both iliac arteries had intense perivascular fibrosis, making arterial anastomosis impossible. The only remaining option for the implant was the infrarenal aorta, with venous drainage to the superior mesenteric vein and exocrine drainage to the gastric antrum. RESULTS: The patient had an uneventful recovery and graft function appeared normal. This report shows that when the recipient's abdominal cavity does not provide clear access for the usual surgical techniques regarding exocrine drainage, the stomach drainage procedure is an option. CONCLUSION: Duodenum-stomach anastomosis might be an alternative to portal enteric drainage because there is easy access for graft biopsies and even for procedures involving the papilla major.

OBJECTIVE: To evaluate the heterogeneity and the coexistence of diabetic neuropathy (DNP) in type 1 (T1DM) and 2 (T2DM) diabetes mellitus. METHODS: 74 T2DM and 20 T1DM patients were evaluated according to age (years), time from diagnosis of diabetes (TDD, years), body mass index (BMI, kg/m(2)), HbA1c and DNP type (American Diabetes Association criteria). RESULTS: T1DM was younger (32.7 +/- 11.0 versus 56.9 +/- 10.3; p = 0.0001), leaner (BMI: 23.6 +/- 3.85 versus 28.4 +/- 5.3; p = 0.0005) and they had longer TDD (17.1 +/- 9.7 versus 10.4 +/- 6.8; p = 0.003). Cardiovascular autonomic neuropathy (CAN) (60% versus 32.4%; p = 0.02) and its coexistence with polyneuropathy (PN) (62.5% versus 33.3%; p = 0.03) were more common in T1DM. Chronic painful polyneuropathy (CPP) was more prevalent in T2DM (60.8% versus 30.0%; p = 0.009). Logistic regression showed HbA1c as an independent variable related to PN (p = 0.04) in both groups. TDD (p = 0.03) and CPP (p = 0.003) were related to CAN in T1DM. Age (p = 0.0004) was related to CPP in T2DM. CONCLUSIONS: The DNP have shown a heterogeneity distribution in type 1 and type 2 diabetes mellitus. The related factors to different phenotypes of this complication, apart from hyperglycemia, may be variable between these two types of diabetes mellitus.
