Terahertz imaging demonstrates its diagnostic potential and reveals a relationship between cutaneous dehydration and neuropathy for diabetic foot syndrome patients.

Diabetic foot syndrome, a long term consequence of Diabetes Mellitus, is the most common cause of non-traumatic amputations. Around 8% of the world population suffers from diabetes, 15% of diabetic patients present a diabetic foot ulcer which leads to amputation in 2.5% of the cases. There is no objective method for the early diagnosis and prevention of the syndrome and its consequences. We test terahertz imaging, which is capable of mapping the cutaneous hydration, for the evaluation of the diabetic foot deterioration as an early diagnostic test as well as ulcers prevention and tracking tool. Furthermore, the analysis of our terahertz measurements combined with neurological and vascular assessment of the patients indicates that the dehydration is mainly related to the peripheral neuropathy without a significant vascular cause.

Case Report: Uterine Adenosarcoma With Sarcomatous Overgrowth and Malignant Heterologous Elements.

A 46- year-old woman presented a uterine adenosarcoma originating in the lower uterine segment. The diagnosis was made in an endometrial biopsy and confirmed in the pathological examination of the complete surgical specimen, both identifying heterologous malignant elements. In addition, complementary immunohistochemical studies were performed. We reviewed the literature, illustrating the clinical and morphological characteristics and the differential diagnoses to be evaluated.

Effects of curcumin on brain-derived neurotrophic factor levels and oxidative damage in obesity and diabetes.

We evaluated the effects of curcumin treatment on protein oxidation (PO), lipid peroxidation (LP) and brain-derived neurotrophic factor (BDNF) levels in the hippocampus and frontal cortex (FC) of diabetic db/db mice (DM) and in sera of obese humans. Thus, DM were treated daily with 50 mg/kg of curcumin during an 8-week period. Obese human were treated daily with 500 and 750 mg of curcumin that was administered orally for 12 weeks; BDNF, PO and LP levels in sera were determined at in weeks 0, 2, 6 and 12 of treatment. BDNF levels decreased in hippocampus and FC of DM as compared with untreated wild-type mice. Curcumin improved or restored BDNF levels to normal levels in DM, but curcumin did not have any effect on BDNF levels in sera of obese humans. In hippocampus and FC of DM, hyperglycaemia and curcumin did not have effect on LP levels. Hyperglycaemia increased PO levels in hippocampus and FC, whereas curcumin decreased these levels in hippocampus but not in FC. In sera of obese humans, the 500-mg dose decreased LP levels in weeks 6 and 12 when compared with basal levels, but the 750-mg dose did not have any effect; both doses of curcumin decreased PO levels in weeks 2, 6 and 12 of treatment when compared with basal levels. Present results suggest a therapeutic potential of curcumin to decrease oxidation caused by obesity in humans and also show that curcumin restores BDNF levels in DM.

[Breast feeding and systemic blood pressure in infants]. / La alimentación al seno materno y la presión arterial sistémica en el lactante.

INTRODUCTION: Blood pressure levels in childhood influence these levels in adulthood, and breastfeeding has been considered such as a cardioprotective. We evaluated the association between blood pressure levels and feeding type in a group of infants. MATERIAL AND METHODS: We conducted a comparative cross-sectional study in term infants with appropriate weight at birth, to compare blood pressure levels in those children with exclusively breastfeeding, mixed-feeding and formula feeding. The comparison of groups was performed using ANOVA and multiple regression analysis was used to identify variables associated with mean arterial blood pressure levels. A p value < 0.05 was considered significant. RESULTS: We included 20 men and 24 women per group. Infant Formula Feeding had higher current weight and weight gain compared with the other two groups (p < 0.05). Systolic, diastolic and mean blood pressure levels, as well as respiratory and heart rate were higher in the groups of exclusively formula feeding and mixed-feeding than in those with exclusively breastfeeding (p < 0.05). Multiple regression analysis identified that variables associated with mean blood pressure levels were current body mass index, weight gain and formula feeding. CONCLUSIONS: Infants in breastfeeding show lower blood pressure, BMI and weight gain.
