ABSTRACT

We evaluated the association of cardiovascular autonomic neuropathy (CAN), blood pressure (BP) and Vitamin D (VD) levels before and after high-dose cholecalciferol supplementation (4000/10,000) UI/day) for 12 weeks in patients (N = 67) with type 1 diabetes mellitus (T1DM). Based on this prospective controlled pilot study, patients were divided into group 1 (N = 23 with CAN) and group 2 (N = 44 without CAN). At baseline, group 1 had higher systolic BP (SBP) during sleep (115 ± 14 vs. 107 ± 12 mmHg, p = 0.04) and lower nocturnal dipping (3 ± 5 vs. 8 ± 6%, p = 0.009). Among those with loss of nocturnal dipping, 45.4% (20/44) had CAN, while in normal nocturnal dipping group it occurred only in 13% (3/23) (p = 0.007). Non-dipper group had worse CAN parameters when compared to dipper group [Very low frequency (VLF) (2.5 ± 0.5vs.2.8 ± 0.4 s, p = 0.01), total power (TP) (2.9 ± 0.6 vs. 3.3 ± 0.4 s, p = 0.01), Valsalva coefficient (1.5 ± 0.4 vs. 1.8 ± 0.6, p = 0.06)]. After VD, only group 1 improved CAN parameters [TP (2.5 ± 0.4 vs. 2.8 ± 0.6, p = 0.01) and VLF (2.2 ± 0.4 vs. 2.4 ± 0.5, p = 0.03). Group 1 presented a reduction in morning SBP (120 ± 20 vs. 114 ± 17 mmHg, p = 0.038) and in morning SBP surge (13 ± 13 vs. 5 ± 14, p = 0.04). High-dose VD was associated with improved CAN parameters and reduced awake SBP and morning SBP surge. These findings suggest that VD may benefit patients with cardiovascular autonomic neuropathy.

ABSTRACT

A População em Situação de Rua (PSR) é constituída por um grupo complexo que apresenta necessidades heterogêneas para a sobrevivência nos espaços públicos, aspecto que demanda a abordagem de diversos campos do conhecimento. No âmbito da saúde, conhecer a perspectiva dos profissionais que prestam auxílio a essas pessoas pode contribuir para a melhoria da assistência ofertada. O objetivo desse estudo é conhecer as percepções dos profissionais das Unidades Básicas de Saúde (UBS) e Unidades Básicas de Saúde da Família (UBSF) do município de Araguari (MG) acerca do atendimento da PSR por meio de um instrumento quantitativo. Foi realizado um estudo descritivo com profissionais de saúde da atenção primária do município que realizaram assistência à PSR nos últimos três anos e os resultados foram apresentados por meio da estatística descritiva. Dos 103 profissionais, 55,30% são agentes de saúde que já atenderam pessoas em situação de rua (51,50%). Os profissionais, em sua maioria, se sentem capacitados (53,40%) e satisfeitos (46,60%) com a assistência realizada, apesar de não terem frequentado nenhuma capacitação para esse atendimento (68,70%). Eles sentem empatia (42,37%), e acreditam que as equipes que destinam esse auxílio devem ser multidisciplinares. Conclui-se que os profissionais de saúde da atenção primária de Araguari, por considerarem importante a multidisciplinaridade, realçam um olhar cuidadoso quanto às diversas necessidades demandadas pela condição de vida nas ruas. Apesar de se sentirem preparados e demonstrarem sentimentos positivos em relação à PSR, sinalizam a carência de capacitação profissional voltada para o atendimento a esse grupo específico no município.

ABSTRACT

BACKGROUND: Little is known about the evolution of peripheral arterial disease (PAD) since diagnosis and its association with glycemic and lipid control in patients with Type 2 Diabetes Mellitus (T2DM). OBJECTIVE: Evaluate the actual criteria to start screening PAD with ankle-brachial index (ABI) in T2DM patients and assess its progression and relationship with glycemic and lipid control since diagnosis. METHODS: We performed a 3-year prospective cohort study with two groups: group 1 (978 individuals with T2DM undergoing drug treatment) and group 2 [221 newly diagnosed drug-naive (< 3 months) patients with T2DM]. PAD diagnosis was by ABI ≤ 0.90, regardless any symptoms. RESULTS: As expected, abnormal ABI prevalence was higher in group 1 vs. Group 2 (87% vs. 60%, p < 0.001). However, abnormal ABI prevalence did not differ between patients over and under 50 years in both groups. Our drug-naive group stabilizes ABI (0.9 ± 0.1 vs 0.9 ± 0.1, p = NS) and improved glycemic and lipid control during follow-up [glycated hemoglobin (HbA1c) = 8.9 ± 2.1 vs 8.4 ± 2.3%, p < 0.05; LDL = 132 ± 45 vs 113 ± 38 mg/dL, p < 0.01, respectively]. When compared, patients who evolved with normalization or maintained normal ABI levels at the end [Group A, N = 60 (42%)] with those who decreased ABI to abnormal levels (ABI basal 1.0 ± 0.1 vs final 0.85 ± 0.1, p < 0.001) [Group B, N = 26 (18%)], an improvement in HbA1c (9 ± 2 vs 8 ± 2%, p < 0.05) and a correlation between the final HbA1c with ABI (r = - 0.3, p = 0.01) was found only in the first. In addition, a correlation was found between albuminuria variation and ABI solely in group A (r = - 0.3; p < 0.05). CONCLUSION: Our study suggests that ABI should be measured at diagnosis in T2DM patients, indicating that current criteria to select patients to screen PAD with ABI must be simplified. An improvement in albuminuria and glycemic and lipid control could be related with ABI normalization in newly diagnosed T2DM drug-naive patients.

ABSTRACT

Background: The effect of glycemic control on diabetic kidney disease (DKD) is well known. Recent evidence has suggested that Vitamin D (VD) may have a nephroprotective effect in diabetes, but the relationship between VD, glycemic control, and albuminuria has yet to be clarified. Objective: Evaluate the relationship between 25-hydroxy-vitamin D [25(OH)D], HbA1c, and albuminuria in Diabetes Mellitus (DM). Patients and Methods: Cross-sectional study with 1576 individuals with DM who had 25(OH)D, HbA1c, and albuminuria levels measured. Patients with abnormal creatinine levels were excluded, in order to avoid interference on VD levels by impaired kidney function. Results: Patients with HbA1c ≥7% had lower 25(OH)D when compared to patients with HbA1c <7% (29.7 ± 10.2 vs 28.1 ± 9.9 ng/ml, p = 0.003) and 25(OH)D levels seems to predict 1.5% of HbA1c behavior. The 25(OH)D concentrations in patients with normoalbuminuria were higher than the levels observed in those with micro or macroalbuminuria (29.8 ± 9.0 vs 26.8 ± 8.6 and 25.1 ± 7.6, respectively, p = 0.001), patients who had 25(OH)D <20 ng/ml and 25(OH)D <30 ng/ml were at a higher risk of presenting albuminuria [OR = 2.8 (95% CI = 1.6 - 4.9), p<0.001, and OR = 2.1 (95% CI = 1.3 - 4.6), p<0.001, respectively]. In our regression model, albuminuria was influenced by HbA1c (r² = 0.076, p<0.00001) and 25(OH)D (r² = 0.018, p = 0.002) independently. Conclusion: Our study found an association between vitamin D levels, HbA1c and DKD. Additionally, our data suggest that the association between urinary albumin excretion and vitamin D levels is independent of glycemic control in patients with diabetes. Even though our patients presented normal creatinine levels, it is necessary further prospective studies to confirm if this association precedes or not the loss of renal function.

ABSTRACT

BACKGROUND: Vitamin D (VD) deficiency has been related to several endocrine metabolic and cardiovascular diseases. The effect of VD supplementation on blood pressure (BP) in patients with diabetes is controversial. OBJECTIVE: The aim of this study was to evaluate high-dose vitamin D supplementation effects on blood pressure of normotensive patients with diabetes mellitus 1 (DM1) patients by 24-hour ambulatory blood pressure monitoring (ABPM). METHODS: We performed a clinical trial including 35 DM1 normotensive patients, who received doses of 4,000 or 10,000 IU/day of cholecalciferol for 12 weeks according to previous VD levels. They underwent 24-hour ABPM, along with glycated hemoglobin, creatine, lipids profile and PCRus dosage before and after VD supplementation. RESULTS: We found an expressive reduction of systolic and diastolic morning blood pressures (117±14 vs 112±14, p<0,05; 74±9 vs 70±10 mmHg, p<0,05, respectively) with no changes in other pressoric markers. Besides, we noticed a relationship between levels of VD after supplementation and diastolic morning blood pressure (r= -0,4; p<0.05). CONCLUSION: Our study suggests an association between supplementation of high doses of vitamin D and the reduction of morning blood pressure in normotensive DM1 patients.

ABSTRACT

Background: Cardiovascular autonomic neuropathy (CAN) is associated with diabetes mellitus, increasing morbidity and mortality. Some cross-sectional studies associated CAN with low 25-hydroxyvitamin D levels. The aim of our study was to evaluate the effect of high-dose vitamin D (VD) supplementation on CAN in Type 1 Diabetes Mellitus (T1DM) patients. Methods: We performed a prospective study with 23 patients diagnosed with T1DM and CAN. Subjects with VD levels <30 ng/ml received 10,000 IU/day; the ones with VD levels between 30-60 ng/ml were given 4,000 IU/day for 12 weeks. Results: There was an improvement in CAN parameters related to resting heart rate variability, such as time domain parameters [Maximum RR interval (0.77 ± 0.11 vs 0.94 ± 0.51 s, p <0.05), Mean length of regular RR intervals (0.71 ± 0.10 vs 0.76 ± 0.09 s, p <0.05) and Standard deviation of all NN intervals (0.02 ± 0.01 vs 0.03 ± 0.02 s; p <0.01)] and frequency domain parameters [Low Frequency (1.9 ± 0.5 vs 2.5 ± 0.9 s, p < 0.001), Total Power (2.5 ± 0.4 vs 2.8 ± 0.6 s, p <0.05)]. In addition, there was a correlation between absolute VD level variation and posttreatment High Frequency (%), as well as among percent variation in VD level and end-of-study Low Frequency/High Frequency ratio (r=0.6, p<0.01; r= -0.5, p<0.05, respectively). Conclusion: Our pilot study is the first to suggest a strong association between high-dose vitamin D supplementation and improved cardiovascular autonomic neuropathy in T1DM patients. It occurred without any variation in HbA1C, blood pressure levels, lipids, and insulin dose. Clinical Trial Registration: http://www.isrctn.com/ISRCTN32601947, identifier ISRCTN32601947.

ABSTRACT

OBJECTIVE: To validate the need for prescribing low-fat diet in the prevention or reduction of dyspeptic symptoms in the postoperative period in patients undergoing laparoscopic cholecystectomy. METHODS: We selected 40 patients, free of liver or pancreatic disease, biliary gallstones, gastritis, ulcer, diabetes and dyslipidemia, who were divided into two groups. We conducted dietary anamnesis, identification of dyspepsia before the onset of cholelithiasis and guidance on appropriate postoperatively feeding (normal or low-fat). We used the chi-square test and Pearson correlation for statistical assessment, considering p d" 0.05 as significant. RESULTS: When comparing the two groups of patients without preoperative dyspepsia, it was observed that in group I seven patients (63.6%) were asymptomatic and in group II, four (66.7%). In group I, four (36.4%) had onset of symptoms and in group II, two (33.3%), p = 0.684. When correlating the two groups with preoperative dyspeptic symptoms, it was observed that there was permanence, appearance or disappearance of symptoms postoperatively, p = 0.114. CONCLUSION: There was no significant effect of low-fat diet in the prevention of gastrointestinal symptoms, especially in preoperatively asymptomatic patients. Thus, there is no need of a low-fat diet. So, it is up to the surgeon to evaluate each patient individually and adjust the diet to his/her needs and clinical conditions.

ABSTRACT

OBJETIVO: Validar a necessidade da prescrição da dieta hipolipídica na prevenção ou redução dos sintomas dispépticos no período pós-operatório de pacientes submetidos à colecistectomia por videolaparoscopia. MÉTODOS: Foram selecionados 40 pacientes, distribuídos em dois grupos, isentos de doenças hepáticas, pancreáticas, litíase da via biliar, gastrite, úlcera, diabetes e dislipidemia. Foi realizado anamnese alimentar, identificação de dispepsias antes do aparecimento da colelitíase e orientações sobre a conduta alimentar no pós-operatório (normal ou hipolipídica). Foi utilizado o teste chi-square e a correlação de Pearson, considerando pd"0,05 como significância estatística. RESULTADOS: Comparando-se os dois grupos de pacientes sem dispepsias no pré-operatório, observou-se que no grupo I, sete pacientes (63,6%) permaneceram assintomáticos e no grupo II, quatro (66,7%). No grupo I, em quatro (36,4%) houve aparecimento de sintomas e no grupo II, em dois (33,3%), logo p=0,684. Correlacionando-se os dois grupos dispépticos no pré-operatório, observou-se que houve permanência, aparecimento ou desaparecimento dos sintomas no pós-operatório, sendo p=0,114. CONCLUSÃO: Não houve repercussão significativa da dieta hipolipídica na prevenção dos sintomas dispépticos, principalmente nos pacientes assintomáticos no pré-operatório. Sendo assim, não há necessidade em se orientar uma dieta hipolipídica. De modo que, cabe ao cirurgião avaliar cada paciente individualmente e ajustar a dieta às necessidades do paciente e às condições clínicas associadas.
