Positive and negative sexual cognitions: similarities and differences between men and women from southern Spain

The aim of this study was to explore the frequency of sexual cognitions in Spanish men and women, distinguishing between positive sexual cognitions (PSC) and negative sexual cognitions (NSC), and various subtypes of such cognitions based on their content (intimate, exploratory, dominance, submission, and impersonal). We also examined the relationship between both age and education level and Christian religion/religiosity and the frequency of all subtypes of sexual cognitions. The sample was composed of 1332 participants aged between 18 and 45 years. Results showed that the most and least frequent sexual cognitions were intimate and sadomasochistic cognitions, respectively. Overall, men reported a higher frequency of PSC than did women, except for cognitions involving submission. In addition, undergraduate students reported a higher frequency of dominant PSC than older individuals. Regarding NSC, men reported a higher frequency of dominance themes, while women reported more frequent cognitions involving submission. In addition, intimate, exploratory, and impersonal NSC were more frequently reported in the younger sample. Religion was associated with the frequency of most PSC but not with NSC. We discuss the implications of assessing both the affect and content of sexual cognitions for their training in sex therapy.     

Haplotypes of the IL10 Gene as Potential Protection Factors in Leprosy Patients

Leprosy is an infectious disease caused by Mycobacterium leprae characterized by dermatoneurological signs and symptoms that has a large number of new cases worldwide. Several studies have associated interleukin 10 with susceptibility/resistance to several diseases. We investigated haplotypes formed by three single nucleotide polymorphisms (SNPs) located in the IL10 gene (A-1082G, C-819T, and C-592A) in order to better understand the susceptibility to and severity of leprosy in an admixed northern Brazil population, taking into account estimates of interethnic admixture. We observed the genotypes ACC/ACC (P = 0.021, odds ratio [OR] [95% confidence interval (CI)] = 0.290 [0.085 to 0823]) and ACC/GCC (P = 0.003, OR [95% CI] = 0.220 [0.504 to 0.040]) presenting significant results for protection against leprosy development, framed in the profiles of low and medium interleukin production, respectively. Therefore, we suggest that genotypes A-1082G, C-819T, and C-592A formed by interleukin-10 polymorphisms are closely related to protection of the leprosy development in an admixed northern Brazil population, in particular ACC/ACC and ACC/GCC genotypes.     

Hematocrit, urea and gender: the Hematocrit, Urea and GEnder formula for prognosing progressive renal failure in diabetic nephropathy

ObjectiveDiabetic nephropathy is a common cause of end stage renal disease. Notwithstanding, wide inter-individual variations in the speed of progression of diabetic nephropathy are frequent. We have used the score of the HUGE formula to predict progression of kidney disease in a group of diabetic nephropathy patients.Design and methodsThe sample consisted of 84 type 2 diabetic patients. At treatment entry, the mean age was 62.1 ± 12.5 years and 59.5% were male. Blood pressure was measured at office at each visit. Serum creatinine, urea, hematocrit and 24 h proteinuria were analyzed every 6 months. HUGE score was calculated from gender, urea and hematocrit.ResultsMean HUGE score was 0.99 ± 3.88. Using as cut off point 1.5, those patients who had a score equal or higher (n = 31) showed a bigger increase in serum creatinine after one year (41.8 ± 62.1%) than those subjects with score < 1.5 (n = 53) (18.7 ± 38.6%, p = 0.041). 5 patients with low HUGE score reached end stage renal failure (9.4%) and 10 patients in the high HUGE score group (32.3, p = 0.008). When logistic regression analysis was performed only a HUGE score higher than 1.5 (p = 0.003) and proteinuria higher than 2 g/day (p = 0.041) were independently associated to CRF progression (creatinine increment > 25%).ConclusionsIn diabetic nephropathy patients the HUGE equation may be useful to detect the subjects prone to progressive renal failure. Wider samples will be needed to confirm this finding and, most important, its applicability to other kinds of nephropathy.     

Mediterranean diet supplemented with coenzyme Q10 modifies the expression of proinflammatory and endoplasmic reticulum stress-related genes in elderly men and women

We have investigated whether the quality of dietary fat and supplementation with coenzyme Q(10) (CoQ) modifies expression of genes related with inflammatory response and endoplasmic reticulum stress in elderly persons. Twenty participants received three diets for 4 weeks each: Mediterranean diet + CoQ (Med + CoQ), Mediterranean diet (Med), and saturated fatty acid-rich diet (SFA). After 12-hour fast, volunteers consumed a breakfast with a fat composition similar to that consumed in each of the diets. Med and Med + CoQ diets produced a lower fasting calreticulin, IL-1b, and JNK-1 gene expression; a lower postprandial p65, IKK-b, MMP-9, IL-1b, JNK-1, sXBP-1, and BiP/Grp78 gene expression; and a higher postprandial IkB-a gene expression compared with the SFA diet. Med + CoQ diet produced a lower postprandial decrease p65 and IKK-b gene expression compared with the other diets. Our results support the anti-inflammatory effect of Med diet and that exogenous CoQ supplementation in synergy with a Med diet modulates the inflammatory response and endoplasmic reticulum stress.     

Study of Bone Mass in Young Daughters of Women With Fracture of the Distal End of the Radius

The main aim was to assess whether young and healthy daughters of women with fractures of the distal end of the radius (DER) had less bone mass than the control group. In an observational study of cases and controls (1:1), the daughters of women with fractures of DER (96) were selected at the age of reaching the peak of bone mass and compared with a control group (91). All women underwent medical history, analytical determinations, and densitometry. In the case group, we found lower bone mass values at the spine and femoral neck than the control group. We also found a lower bone mass at the hips of daughters of women with 1 or more osteoporotic fractures associated with DER and at the lumbar spine in those whose mothers had densitometric osteoporosis. In conclusion, young daughters of women with fractures of DER had lower levels of bone mass density, with a possible “location-specific” occurrence based on the presence of 1 or more osteoporotic fractures associated with DER or on the presence of maternal densitometric osteoporosis.     

New look at nutritional care for obese patient candidates for bariatric surgery

BackgroundThe combination of preoperative deficiencies and the restrictions and malabsorption possibly induced by bariatric surgery could lead patients to experience important nutritional deficits during the late postoperative period. Our objective was to characterize the eating, anthropometric, and biochemical profiles of obese candidates for bariatric surgery at a bariatric surgery center of a university hospital.MethodsA retrospective study with the analysis of medical records of candidates for bariatric surgery from 2007 to 2008 was performed. A total of 80 adult patients, aged 45 ± 11 years, were included in the present study.ResultsThe mean patient weight was 145 ± 24 kg, and the mean body mass index was 54 ± 8 kg/m². Of the 80 patients, 78% had ≥1 co-morbidities related to obesity. The reported daily energy intake before surgery was 1981 ± 882 kcal, with 48% ± 11% consisting of carbohydrate, 29% ± 8% of lipids, and 23% ± 8% of protein. The mean number of daily meals was 4 ± 1. Patients with a greater body mass index ingested a smaller amount of calories per kilogram of current weight. The occurrence of hyperglycemia, hyperuricemia, and dyslipidemia and of nutritional deficiencies, among them magnesium (19%), vitamin A (15%), vitamin C (16%), iron (9%), β-carotene (3%), and vitamin B₁₂ (3%), was high.ConclusionThe high occurrence of micronutrient deficiency detected by biochemical analysis in morbidly obese candidates for bariatric surgery, representing a disabsorptive process, might involve a poorer prognosis during the late postoperative period. A preoperative evaluation of the nutritional parameters and the food intake pattern is recommended for these patients, together with the necessary interventions.
