Objective: To evaluate the influence of maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) on blood glucose levels at diagnosis of gestational diabetes mellitus (GDM) and obstetric/neonatal outcomes. Subjects and methods: Retrospective cohort study including 462 women with GDM and singleton pregnancy delivered in our institution between January 2015 and June 2018 and grouped according to BMI/GWG. Results: The diagnosis of GDM was more likely to be established in the 1 st trimester (T) in women with obesity than in normal-weight (55.8% vs 53.7%, p = 0.008). BMI positively and significantly correlated with fasting plasma glucose (FPG) levels in the 1 st T (rs = 0.213, p = 0.001) and 2 nd T (rs = 0.210, p = 0.001). Excessive GWG occurred in 44.9% women with overweight and in 40.2% with obesity (p < 0.001). From women with obesity, 65.1% required pharmacological treatment (p < 0.001). Gestational hypertension (GH) was more frequent in women with obesity (p = 0.016). During follow-up, 132 cesareans were performed, the majority in mothers with obesity (p = 0.008). Of the 17 large-for-gestational-age (LGA) birthweight delivered, respectively 6 and 9 were offsprings of women with overweight and obesity (p = 0.019). Maternal BMI had a predictive value only for macrosomia ), p = 0.041]. BMI and GWG positively correlated with birthweight (rs = 0.132, p = 0.005; rs = 0.188, p = 0.005). Conclusion: Maternal obesity is related with a major probability of diagnosis of GDM in 1 st T, fasting hyperglycemia in 2 nd T and a more frequent need for pharmacological therapy. Pre-gestational obesity is associated with GH, cesarean delivery and fetal macrosomia.

Background and aimsDiabetic foot ulcer location is a known independent predictor for cure with a better healing gradient proximal to distal. Although advanced age is one of the main factors associated with greater diabetic foot ulcer severity, there are no studies evaluating diabetic foot ulcer location specifically in the elderly population in an outpatient setting. This study evaluated diabetic foot ulcer location and age-group interactions in diabetic foot presentation. MethodsA retrospective cohort study including adult patients with diabetic foot ulcers observed on their first visit to our center's Diabetic Foot Unit in 2018, divided into younger adults (YA) (18 to 64 years) and older adults (OA) (≥65 years). ResultsA total of 435 patients were included in the study with 159 (36.6%) in the YA, and 276 (63.4%) in the OA group.Neuro-ischemic diabetic foot ulcers were more frequent in the OA group (71.4% vs 43.4%, p<0.001). The number of patients with a history of diabetic foot ulcers was lower in the OA group (18.1% vs 25.2%, p=0.03). A smaller proportion of forefoot diabetic foot ulcers (74.9% vs 86.2%, p=0.007) and plantar location diabetic foot ulcers (9.4% vs 24.5%, p<0.001) occurred in the OA group.By univariate logistic regression analysis, we found two associations with older age: proximal (odds ratio (OR) 2.09 (1.23-3.53), p=0.006), and non-plantar (OR 3.13 (1.82-5.37), p<0.001) diabetic foot ulcer location. After adjusting for potential confounders in a multivariate analysis, older age lost the association to more proximal , p=0.081) and non-plantar (OR 1.78 (0.83-3.77), p=0.133) diabetic foot ulcer location. ConclusionsThere are essential age differences in diabetic foot ulcer presentation. The OA group more frequently presents neuro-ischemic diabetic foot ulcers with more proximal and non-plantar locations.

The increase in life expectancy along with technological advances has translated into a higher number of pituitary adenomas (PA) diagnosed from the age of 65. In the elderly, symptoms related to comorbidities might overlap with endocrine dysfunction, in addition to increasing anesthetic and surgical risks. This study aimed to compare baseline clinical and tumor features between patients with PA from different age groups: younger adults (YA), 18 to 64 years, and older adults (OA), ≥65 years. As secondary outcomes, we also intended to assess: clinical characteristics and tumor features in patients undergoing surgical intervention and surgical data and complications in patients undergoing transphenoidal surgery (TSS). This retrospective cohort study included patients diagnosed with PA in adulthood divided into YA and OA groups. The secondary outcomes were evaluated in the subgroups: patients who underwent pituitary surgery and patients specifically submitted to TSS, who had completed postoperative follow-up ≥ 6 months until July/2020. A total of 401 patients were included, 327 (81.5%) in the YA and 74 (18.5%) in the OA group. Hormone-secreting effects were more common in the YA group ( P < .001) and mass effects in the OA group ( P = .070). The prevalence of hypertension and diabetes was higher in the OA group ( P = .002, P = .011). A larger proportion of nonfunctioning (NF) PA and prolactinomas was found in OA ( P < .001) and YA ( P = .012), respectively. Macroadenomas were more common in the OA group ( P < .001). No differences were found in terms of invasiveness. In the secondary outcome analysis, there was a higher prevalence of NF-PA in those who underwent pituitary surgery. The rate of TSS-related complications was similar between the groups for major, minor and endocrine/electrolyte complications. OA-PA clinically differ from the younger: tend to present more frequently with chronic comorbidities and less frequently with hormone-secreting effects, are more often NF and larger in size without a significant increase in invasiveness. The TSS results were reassuring, proving to be equally safe for the elderly.
