Aims To determine the occurrence of microalbuminuria in young people with Type 1 diabetes mellitus followed prospectively for 2 years and to relate the presence of persistent elevations in urinary albumin excretion (UAE) to age, diabetes duration, puberty and other factors. Methods During a 2 year period, random urine samples were obtained from 471 patients, aged 8–18 years (mean ± SD 12.9 ± 2.3 years) with Type 1 diabetes duration 5.6 ± 3.0 years, as part of routine clinical care. Urine albumin and creatinine concentrations were measured in 1310 samples (median, 3 samples per patient) and the albumin:creatinine ratio was calculated (in micrograms albumin per milligram creatinine). Height, weight, blood pressure (BP), glycated haemoglobin (HbA1c), blood glucose monitoring frequency and Tanner staging were collected from patients’ medical records. Results Twenty-three per cent of patients had one or more sample with elevated UAE (≥20 μg/mg) and 9.3% had persistent elevations (≥2 samples ≥20 μg/mg). Those with and without persistent microalbuminuria did not differ significantly in age, diabetes duration, z–score for body mass index, pubertal status or BP percentile. Ten per cent of children <13 years old and 9% of children ≥13 years old had persistent microalbuminuria. Persistent microalbuminuria was significantly associated with diabetes duration only in older children (duration 0.5–3 years, 4%; 4–6 years, 8%; ≥7 years, 14%; P = 0.02, trend test). Mean HbA1c over the 2 years was 8.7 ± 1.2%. In a logistic regression model, mean HbA1c was the only significant predictor of persistent microalbuminuria (odds ratio 1.3, 95% confidence interval 1.0–1.6, P = 0.05). Conclusions Microalbuminuria in older children with Type 1 diabetes is likely to be clinically significant. In younger children, it may reflect functional, reversible renal changes. Longitudinal analysis is needed to confirm the probable transient nature of microalbuminuria in young patients with Type 1 diabetes.
Nurses are at risk of having burnout due to workload and job stress—studies have reported that chronic stress is associated with metabolic syndrome. This study aimed to assess the association between burnout and metabolic syndrome in a sample of female nurses. Data were collected from a cross-sectional study from 2016 to 2018 in a tertiary hospital in Mexico City. All nurses that work in the hospital were invited to participate. Information pertaining to sociodemographic (age, education level), work (labor seniority, service area, shift work), anthropometric (weight, waist circumference, blood pressure) and biochemical (glucose, serum lipids) variables were collected. Burnout was assessed using the Maslach Burnout Inventory test, and metabolic syndrome was defined according to the International Diabetes Federation criteria. A total of 168 nurses participated with a median age of 44 years. The prevalence of burnout and metabolic syndrome was 19.6% and 38.7%, respectively. There was no association between burnout and metabolic syndrome (p = 0.373). However, associations of emotional exhaustion (aOR: 14.95; 95% CI: 1.5–148.7), personal accomplishment (aOR: 0.13; 95% CI: 0.01–0.99), and night shift (aOR: 12.39; 95% CI: 1.02–150.5) with increased waist circumference were found. Strategies are needed to prevent burnout and metabolic syndrome in nurses, especially in those who work at night shift.
SummaryPancreas transplantation is an option to achieve better metabolic control and decrease chronic complications in patients with diabetes. Xenotransplantation becomes an important alternative. In this study, we show the clinical outcome of patients with type 1 diabetes transplanted with neonatal pig islets without immunosuppression. In a longitudinal study of 23 patients with type 1 diabetes, who received porcine islets between 2000 and 2004, we registered demographic and clinical characteristics every 3 months and chronic complications evaluation yearly. Porcine C-peptide was measured in urine samples under basal conditions and after stimulation with l-arginine. More than 50% were female, median current age was 20·8 years, median diabetes duration at transplantation 5·5 years, median current diabetes duration 11 years and median time post-transplantation 5·7 years. Their media of glycosylated haemoglobin reduced significantly after the first transplantation. Insulin doses remain with a reduction greater than 33% in more than 50% of the patients. Before transplantation, 14 of the 21 patients presented mild chronic complications and currently only two patients presented these complications. Porcine C-peptide was present in all urine samples under basal conditions and increased post-stimulation with l-arginine. These patients achieved an excellent metabolic control after the first transplantation. This could explain, as well as the remaining function of transplanted cells, the low frequency of chronic complications compared to patients with similar diabetes duration and age.
Xenotransplantation is a promising alternative for donor shortage to ameliorate physiologic and metabolic disorders. The major concern for xenotransplant is the risk of zoonosis mainly by the porcine endogenous retrovirus (PERV), presentation in the piglet genome. Twenty-three patients with type 1 diabetes were transplanted with porcine islets using collagen-generating devices which were implanted subcutaneously in the anterior wall of the abdomen. Clinical characteristics and metabolic tests were recorded in each visit. They were tested for PERV using PCR and RT-PCR from blood pretransplantation and every 3 months during a 4.6- to 8-year follow-up after their first xenotransplant. Tests by PCR of every DNA sample (780 samples) revealed that there was no PERV infection in the DNA of white cells. No evidence of PERV activation was found in this group of patients with type 1 diabetes during clinical long-term follow-up.
BackgroundIn the last 20 years, adolescent pregnancy has become one of the most critical problems affecting women in Latin America and the Caribbean.MethodsThis qualitative study was based on in-depth interviews with 29 teen mothers. All of the pregnant teens were from low- to lower-middle-class social strata in the Mexico City metropolitan area. The family (living with the girl) and the individual context of pregnant teens were analysed on the basis of data from at least three interviews: during pregnancy and at approximately 6 and 24 months following delivery. Additionally, six mothers, four fathers, and four partners of the pregnant girls of the group were interviewed. The information on the individual and family situation before, during and after the pregnancy was recorded and transcribed, then analysed in three phases, comprising pre-analysis, exploration and interpretation.ResultsThe pregnant teens had a family background of teen pregnancy. The girls disclosed feelings of repression, loneliness and indifference to their parents, leading them to unprotected sexual relations without fear of pregnancy. After the pregnancy, communication improved between the girls and their parents, but became worse with their partner. Consequently, these teens returned to feeling as they did before getting pregnant. They stated that they would make their situation work for the sake of their child, and regretted dropping out of school and getting pregnant so young. Almost all said they were seeking love outside the family, which revealed a scenario of limited communication and unsatisfactory relations within the family.ConclusionsUnderstanding how communication works between parents and children is necessary to avoid teenage pregnancy, as well as early marriage or cohabitation, resulting in dropping out of school and financial constraints, which lead to great frustrations between the couple and affects the child. In addition, it is vitally important that adolescents be motivated in the family setting in order for them to continue their studies. There is also an urgent need to implement measures that compensate for educational inequality, as well as to strengthen strategies aimed at adolescent mothers and pregnant teens that encourage their school performance through the support of scholarship programs and day care centres. Many of the problems inherent in adolescence are related to the lack of affection and support, and in many cases are a reaction to authoritarian rules or limits established unilaterally by parents with little or no dialogue involved.Electronic supplementary materialThe online version of this article (10.1186/s12884-017-1570-7) contains supplementary material, which is available to authorized users.
