Morningness/eveningness in gestational diabetes mellitus: clinical characteristics and maternal-neonatal outcomes

ABSTRACT Objective: This study aims to evaluate the impact of morning-evening preference in pregnancy outcomes in gestational diabetes mellitus (GDM). Materials and methods: This is a prospective cohort study of 2nd-3rd trimester GDM outpatient care in Fortaleza, Brazil (2018-2020). Eveningness was defined by the Horne-Östberg Morningness-Eveningness-Questionnaire (MEQ ≤ 41). Furthermore, we obtained a 7-day actigraphic register. Subjective sleep quality, daytime somnolence, insomnia, fatigue and depressive symptoms were also evaluated. Associations with pregnancy outcomes were investigated. Results: Among 305 patients with GDM, evening preference was found in 21 (6.9%). Patients with evening preference had worse sleep quality (p < 0.01), greater severity of insomnia (p < 0.005), fatigue (p < 0.005) and depressive symptoms (<0.009). Evening chronotype was associated with preeclampsia [p = 0.01; OR = 0.27; CI 0.09-0.79] and a greater need for admission to a neonatal intensive care unit (NICU) [p = 0.02; OR = 0.23; CI .0.06-0.80]. A lower MEQ score confirmed an association with preeclampsia [p = 0.002; OR = 0.94; CI 0.90-0.97] and this was maintained after controlling for age, arterial hypertension, sleep quality, fatigue and depressive symptoms [p < 005; OR = 0.91; CI 0.87-0.95]. Conclusion: In GDM, patients with evening preference had worse sleep quality, more insomnia, fatigue, and depressive symptoms. Furthermore, eveningness was independently associated with preeclampsia. These results indicate the important role of eveningness in adverse pregnancy outcomes.

Hyperglycemia in pregnancy: sleep alterations, comorbidities and pharmacotherapy.

OBJECTIVE: To investigate sleep alterations and associated factors in pregnant diabetic women (n=141). METHODS: Sleep profile, sociodemographics and clinical information were collected. Poor sleep quality (Pittsburgh Sleep Quality Index >5) and excessive daytime sleepiness (Epworth Sleepiness Scale ≥10), sleep duration (h), sleep latency (min), frequent sleep interruption and short sleep (≤6 h) were assessed in type 1 diabetes mellitus (16.3%), type 2 diabetes mellitus (25.5%) and gestational diabetes mellitus (58.2%). RESULTS: Poor sleep quality was found in 58.8% of patients and daytime sleepiness in 25.7%, regardless of hyperglycemia etiology. No correlation existed between daytime sleepiness and poor sleep quality (Pearson correlation r=0.02, p=0.84). Short sleep duration occurred in 1/3 of patients (31.2%). Sleep interruptions due to frequent urination affected 72% of all and sleep interruptions due to any cause 71.2%. Metformin was used by 65.7% of type 2 diabetes mellitus and 28.7% of gestational diabetes mellitus. In gestational diabetes mellitus, parity number was independently associated with poor sleep quality (p=0.02; OR=1.90; 95%CI 1.07-3.36) and metformin use was also independently associated with poor sleep quality (p=0.03; OR=2.36; 95%CI 1.05-5.29). CONCLUSIONS: Our study originally shows that poor sleep quality and excessive daytime sleepiness are frequent in diabetic pregnancy due to different etiologies. Interestingly, only in gestational diabetes mellitus, metformin therapy and higher parity were associated with poor sleep quality.

Rastreamento e diagnóstico de diabetes mellitus gestacional no Brasil / Screening and diagnosis of gestational diabetes mellitus in Brazil

Em primeiro de agosto de 2016, considerando-se a relevância do Diabetes Mellitus Gestacional (DMG), tanto por sua prevalência como pelas consequências para o binômio materno-fetal em curto e em longo prazo, foi realizado, em São Paulo, um fórum de discussão sobre o tema, com o objetivo de definir uma proposta para o diagnóstico de DMG para o Brasil. Nesse contexto, participaram da reunião médicos especializados na assistência a mulheres com DMG: obstetras da Federação Brasileira de Ginecologia e Obstetrícia (Febrasgo), endocrinologistas da Sociedade Brasileira de Diabetes (SBD) e consultores da Organização Panamericana de Saúde (Opas/OMS Brasil) e assessores técnicos do Ministério da Saúde. Apresentamos neste documento os principais pontos debatidos visando à análise cuidadosa das possibilidades para diagnóstico de DMG, considerando-se as diferenças de acesso aos serviços de saúde existentes no Brasil.(AU)

Physical activity level in women with gestational diabetes mellitus: Lifestyle INtervention for Diabetes prevention After pregnancy (LINDA-Brasil) study.

BACKGROUND: The aim of this study was to investigate physical activity and associated factors in women with gestational diabetes mellitus (GDM). METHODS: This cross-sectional study was performed on 2706 women as part of the Lifestyle INtervention for Diabetes prevention After pregnancy (LINDA-Brasil) study, recruited between 2012 and 2016 in Brazil. A structured questionnaire was used to assess physical activity. Descriptive and Poisson regression analyses were used to investigate physical activity and associated factors. RESULTS: Counseling regarding physical activity practices was reported by 47.4% and 34.3% of women before and after a diagnosis of GDM, respectively. During pregnancy, 26% of women were classified as inactive, 39.7% were classified as insufficiently active, and 34.3% were classified as active. Compared with prepregnancy, 63.1% of women reported a decrease in physical activity levels during pregnancy. The prevalence of being inactive during pregnancy was higher among women who did not live with a partner (P = 0.003), had a lower household income (P = 0.01), were employed (P < 0.001), and who had four or more children (P < 0.001). CONCLUSION: Among Brazilian women with GDM, physical activity levels and practices were low, with most women reporting decreased physical activity during pregnancy. A low socioeconomic status was associated with lower physical activity. These findings indicate the need to reinforce the importance of physical activity in the management of GDM in Brazil.

Adiponectin levels and sleep deprivation in patients with endocrine metabolic disorders.

BACKGROUND: Sleep abnormalities are frequent in patients with endocrine metabolic disorders (EMD) such as arterial hypertension, diabetes and obesity. Adiponectin is a peptide largely secreted by adipocytes and has various properties e.g. anti-inflammatory, antioxidant, antiatherogenic, pro-angiogenic, vasoprotective and insulin-sensitizing. Adiponectin inversely relates to body weight and when its concentration decreases, the resistin concentration increases resulting in greater insulin resistance. OBJECTIVE: The objective of this study is to examine factors influencing adiponectin levels in a population with EMD. METHODS: This was a cross-sectional evaluation of 332 patients (18 to 80y) presenting arterial hypertension, pre-diabetes, diabetes, and/or obesity. Investigation included clinical evaluation of comorbidities, general blood tests and adiponectin measures (ELISA). Chronic sleep deprivation was determined if habitual sleep was <6 hours >4 days/week. RESULTS: Arterial hypertension (78.5%), type-2 diabetes (82.3%), and overweight (45.0%)/obesity (38.8%) were frequent. Patients with type-2 diabetes tended to have more chronic sleep deprivation (p=0.05). Adiponectin levels increased with age and were inversely correlated with sagittal abdominal diameter (p=0.04) and fasting insulin (p=0.001). Chronic sleep deprivation was associated with higher adiponectin concentration [OR=1.34; CI=1.13-1.58; p<0.005] and this was maintained after adjustment for gender, age, body mass index, menopause, arterial hypertension, American Diabetes Association classification and physical exercise levels [OR=1.38; 0=1.14-1.66: p=0.001]. CONCLUSION: In patients with EMD, adiponectin is influenced not only by obesity but also by age and sleep deprivation. The latter finding may be explained by a compensatory effect or a counter regulation to minimize the harmful effects of sleep deprivation.

RESUMO INTRODUÇÃO: Problemas de sono são frequentes em pacientes com distúrbios endócrino-metabólicos (DEM), como hipertensão arterial, diabetes e obesidade. A adiponectina é um peptídeo segregado por adipócitos e apresenta diversas propriedades, como por exemplo, anti-inflamatória, antioxidante, antiaterogênica, pró-angiogênica e vasoprotetora. A adiponectina relaciona-se inversamente com o peso corporal. OBJETIVO: Examinar os fatores que influenciam os níveis de adiponectina em uma população com DEM. MÉTODOS: Trata-se de uma avaliação transversal com 332 pacientes (18 a 80 anos) apresentando hipertensão arterial, pré-diabetes, diabetes e/ou obesidade. A investigação incluiu avaliação clínica de comorbidades, exames de sangue e medidas de adiponectina (Elisa). A restrição crônica do sono foi determinada com o sono habitual <6 horas >4 dias/semana. RESULTADOS: Doenças como hipertensão arterial (78,5%), diabetes tipo 2 (82,3%) e sobrepeso (45,0%)/obesidade (38,8%) foram frequentes. Pacientes com diabetes tipo 2 apresentaram uma tendência na restrição crônica do sono (p=0,05). Os níveis de adiponectina aumentaram com a idade e foram inversamente correlacionados com o diâmetro abdominal sagital (p=0,04) e com a insulina em jejum (p=0,001). A restrição crônica do sono foi associada à maior concentração de adiponectina [OR=1,34; CI=1,13-1,58; p<0,005] e isso foi mantido após ajuste por gênero, idade, índice de massa corporal, menopausa, hipertensão arterial, classificação dos níveis da American Diabetes Association e exercício físico [OR=1,38; CI=1,14-1,66: p=0,001]. CONCLUSÕES: Em pacientes com DEM, a adiponectina é influenciada não apenas pela obesidade, mas também pela idade e pela restrição de sono. O último achado pode ser explicado por um efeito compensatório ou por um regulamento contrário para minimizar os efeitos nocivos da restrição do sono.

Depressive Symptoms in Women with Gestational Diabetes Mellitus: The LINDA-Brazil Study.

This study aimed to assess the frequency and severity of depressive symptoms and their relationship with sociodemographic characteristics in women with gestational diabetes mellitus (GDM) who participated in the LINDA-Brazil study. We conducted cross-sectional analyses of 820 women with GDM who were receiving prenatal care in the public health system. We conducted structured interviews to obtain clinical and sociodemographic information and applied the Edinburgh Postnatal Depression Scale (EPDS) to assess depressive symptoms. We classified the presence and severity of depressive symptoms using scores of ≥12 and ≥18, respectively. We used Poisson regression to estimate prevalence ratios (PR). Most of the women lived with a partner (88%), 50% were between 30 and 39 years old, 39% had finished high school, 39% had a family income of 1-2 minimum wages, and 47% were obese before their pregnancies. The presence of depressive symptoms was observed in 31% of the women, and severe depressive symptoms were observed in 10%; 8.3% reported self-harm intent. Lower parity and higher educational levels were associated with lower EPDS score. Depressive symptoms were common and frequently severe among women with GDM, indicating the need to consider this situation when treating such women, especially those who are more socially vulnerable. This trial is registered with NCT02327286, registered on 23 December 2014.

Health-related quality of life and utility values associated to hypoglycemia in patients with type 1 diabetes mellitus treated in the Brazilian Public Health System: a multicenter study.

BACKGROUND: Hypoglycemia is a critical and limiting factor of a good metabolic control and can adversely affect the quality of life of diabetic patients. The aim of the study was to evaluate the health-related quality of life and calculate utilities values associated with hypoglycemia in patients with type 1 diabetes mellitus (T1DM). METHODS: A multicenter, cross-sectional and observational study with T1DM patients from reference centers of the Brazilian public health system was conducted in three cities. Demographic and clinical data were collected, besides details on the frequency and severity of hypoglycemia. Health-related quality of life was assessed using EQ-5D instrument and utility values generated. RESULTS: 221 patients (107 women, 114 men), aged 29.8 ± 11.6 and disease duration of 14.2 ± 9.1 years were included. Most patients (n = 214, 96.8%) reported at least one symptomatic hypoglycemia in the last three months, 68% (n = 150) reported nocturnal episodes and 34.8% (n = 77) reported severe episodes. High frequency (daily or weekly) was observed in 38.6 and 26% of those reporting nocturnal or severe hypoglycemia, respectively. The median visual analog scale was 70 [60-85] for all patients, with differences between those with and without severe hypoglycemia (70 [60-80] vs 80 [61-90]; p = 0.006) and those with high and low frequency (62.5 [50-72.25] vs 70 [60-80]; p = 0.007). The median utility values was 0.801 [0.756-1.000] for all patients, with difference between those with high and low frequency of severe episodes (0.737 [0.628-1.000] vs 0.801 [0.756-1.000]; p = 0.02). CONCLUSIONS: This study shows the high frequency of hypoglycemia in a sample of T1DM patients treated in three reference centers of the Brazilian public health system and the impact of severe episodes on health-related quality of life. Utility values were generated and can be used in economic analysis for treatments that could decrease hypoglycemia and consequently improve quality of life.

Lifestyle INtervention for Diabetes prevention After pregnancy (LINDA-Brasil): study protocol for a multicenter randomized controlled trial.

BACKGROUND: Gestational diabetes mellitus (GDM), a hyperglycemic state detected during pregnancy, is an established risk factor for diabetes. However, treatment during pregnancy in and of itself is not able to eliminate this risk, and a considerable fraction of women with GDM will develop frank diabetes in the decade following pregnancy. Our aim is to conduct a multicenter randomized controlled trial to investigate the effectiveness of a lifestyle intervention program implemented after a pregnancy complicated by GDM in delaying or preventing the development of type 2 diabetes. METHODS: Women aged 18 or older identified as having recent GDM are recruited and followed by telephone to assess eligibility for the trial. To be eligible, women must have used insulin during pregnancy or present intermediate hyperglycemia postpartum. Women are encouraged to enter the trial as early as 10 weeks, and are permitted to do so up to 2 years after a pregnancy with GDM. An estimated 740 women will be randomized to either conventional care or to coach-based interventions focused on breastfeeding, weight loss, healthy eating, and increased physical activity, and predominantly delivered by telephone. Women are followed annually to detect new onset diabetes, the primary outcome, and additional secondary outcomes which include reversion to normoglycemia, weight loss, physical activity and fitness, and insulin resistance. DISCUSSION: Though previous studies have demonstrated that type 2 diabetes can be delayed or prevented, no study has yet demonstrated the feasibility and effectiveness of similar interventions implemented in the postpartum period for women with recent GDM. If shown to be successful, this approach could become an important means of preventing diabetes in primary care settings.

Avaliação da necessidade de tratamento periodontal e índice de cárie radicular numa população de Fortaleza-CE / Evaluation of the periodontal treatment needs and the root caries index in a population of Fortaleza_CE

O objetivo deste estudo foi averiguar a necessidade de tratamento periodontal e a ocorrência de cárie radicular em pacientes acima de 40 anos que procuraram a triagem do curso de Odontologia da UNIFOR. Foram examinados 70 pacientes adultos, dentados. Para análise da necessidade de tratamento periodontal, foi utilizado o índice PSR modificado. A recessão gengival foi medida em milímetros para as faces V, L, M, D de cada dente, e o índice de cárie radicular foi calculado. Foram observados redução do número médio de dentes, remanescentes (40-49 anos: 16,57; 70 ou mais: 10), aumento da porcentagem dos dentes acometidos por recessão gengival (40-49 anos: 49 por cento; 70 ou mais anos: 87 por cento), aumento da recessão gengival média (40-49 anos: 1,04 mm: 70 ou mais anos: 2,96 mm) e redução do índice de cárie radicular (40-49 anos: 0,23; 70 anos ou mais: 0,04) com o aumento da idade. Pacientes com cárie coronária apresentaram risco 1,44 vez maior de desenvolver cárie radicular. A porcentagem de sextantes acometivos com PSR 3 e 4 verdadeiros aumentou em função da idade (40-49 anos: 61 por cento; 70 ou mais anos: 93 por cento). Conclusão: com o aumento da idade, houve aumento da necessidade de tratamento periodontal e redução da ocorrência de cárie radicular
