Is the wearing of elastic stockings for half a day as effective as wearing them for the entire day?

P>Background There is good evidence for the use of compression for some clinical indications but little is known about dosimetry in compression. Objective The aim of this work was to evaluate whether or not the use of compression stockings during part of the day would help in the reduction of evening oedema in patients with clinical, epidemiological, anatomical and physiopathological (CEAP) classifications C0 and C1. Methods The effects of elastic compression stockings on volumetric variations during the working day were evaluated for the legs of two men and 18 women (40 legs). The inclusion criterion was classification as C0 (10 legs) or C1 (30 legs) according to the CEAP criteria. Participants used three-quarter-length elastic compression stockings (20-30 mmHg) on three consecutive days for the entire day or only for the morning or they did not use the stockings at all. Volumetry using the water displacement technique was performed in the morning and in the evening. When the patients wore the stockings only during the morning, volumetry was also performed at 13:00 h. Results Significant increases in volume were observed for both legs when stockings were not used compared with the use of stockings in the morning only. After removing the stockings, both legs had significant increases in volume in the afternoon. However, use for half the day was better than not using the stockings at all. Conclusions The use of elastic compression stockings can reduce volumetric variations during working hours, with the use of stockings for the entire day being better than for just half the day.

Risk factors across the life course and dementia in a Brazilian population: results from the Sao Paulo Ageing & Health Study (SPAH)

Background Several mechanisms have been suggested to explain the association between adversities across life and dementia. This study aimed to investigate the association between indicators of socioeconomic disadvantages throughout the life-course and dementia among older adults in Sao Paulo, Brazil and to explore possible causal pathways. Methods We used baseline data from the SPAH study which involved participants aged 65 years and older (n = 2005). The outcome of interest was prevalent dementia. Exposures included in the analyses were socioeconomic position (SEP) indicators in childhood (place of birth and literacy) and adulthood (occupation and income), anthropometric measurements as markers of intrauterine and childhood environment (head circumference and leg length), smoking, diabetes and hypertension. Logistic regression models were used to test the hypothesized pathways and to assess whether there was an association between cumulative adversities across the life course and prevalent dementia. Results Indicators of socioeconomic disadvantage in early life were associated with increased prevalence of dementia. This association was partially mediated through adulthood SEP. Head circumference and leg length were also clearly associated with dementia but there was no evidence that this association was mediated by early life socioeconomic disadvantage. There was an association between cumulative unfavourable conditions across the life course and dementia. Conclusions Early life disadvantages seem to operate through biological mechanisms associated with passive brain reserve and opportunities in life representing active cognitive reserve. Prevention of dementia should start early in life and continue through life span as seen with many other chronic diseases.

A randomized, placebo-controlled trial of the effects of physical exercises and estrogen therapy on health-related quality of life in postmenopausal women

Objective: The purpose of this study was to evaluate the isolated and associated effects of estrogen therapy (estradiol valerate 1 mg/d orally) and physical exercise (moderate aerobic exercise, 3 h/wk) on health-related quality of life (HRQOL) and menopausal symptoms among women who had undergone hysterectomy. Design: A 6-month, randomized, double-blind, placebo-controlled clinical trial with 44 postmenopausal women who had undergone hysterectomy. The interventions were physical exercise and hormone therapy (n = 9), being sedentary and hormone therapy (n = 14), physical exercise and placebo (n = 11), and being sedentary and placebo (n = 10). HRQOL was assessed by a Brazilian standard version of the Medical Outcome Study Short-Forrn Health Survey and symptoms by Kupperman Index at baseline and after 6 months. Results: There was a decrease in symptoms in all groups, but only groups who performed physical exercise showed an increase in quality of life. Analysis of variance showed that changes in physical functioning (P = 0.001) and bodily pain (P = 0.012) scores over the 6-month period differed significantly between women who exercised and women who were sedentary, regardless of hormone therapy. Hormone therapy had no effect, and there was also no significant association between physical exercise and hormone therapy in HRQOL. Conclusions: Physical exercises can reduce menopausal symptoms and enhance HRQOL, independent of whether hormone therapy is taken.

The effect of early virological response in health-related quality of life in HCV-infected patients

Twenty-nine HCV-infected patients were treated with pegylated interferon alpha. Diagnosis was based on serum HCV RNA-PCR positive results and liver biopsy. All patients had elevated serum levels of alanine aminotransferase at the time of the study, but liver disease was compensated. Patients were evaluated at baseline treatment and after 4 and 12 weeks of antiviral treatment with the Medical Outcomes Study 36-item Short-Form Health Survey. The Mini-International Neuropsychiatric Interview was used to exclude previous or current psychiatric diagnoses. Both patients and psychiatrists were blind to the HCV RNA status, and serum HCV RNA test results only became available after the visit at week 12. After antiviral treatment, 16 patients (55.2%) were classified as nonresponders and 13 (44.8%) were classified as responders. When compared to nonresponders, responders had a greater improvement in the HRQOL scores for the mental health domain (P<.019). Differences in other domains were not significant. The present study confirms that active viral infection is one possible reason for the poor Health-Related Quality of Life in this population.

Assessing the impact of upper blepharoplasty on quality of life with a standardized questionnaire (QBleflaro): a pilot study

BACKGROUND: There is scarce literature on assessing surgical results and the impact of upper blepharoplasty on quality of life of patients. OBJECTIVE: To evaluate the impact on quality of life of patients submitted to upper blepharoplasty. METHODS: A prospective study using a standardized questionnaire applied to adult women submitted to upper blepharoplasty and evaluated 90 days later to estimate the surgical impact on quality of life and complications. RESULTS: Forty-one healthy adult females (median age of 53 years) were evaluated from June 2005 to March 2006. The questionnaire showed high internal consistency. The quality of life element with greater impact on the first postoperative week was related to physical appearance perception and that of lesser impact was associated to relationship with relatives and close friends. Hypertrophic scar was the main late complication. Satisfaction levels with the surgery were significantly related with absence of undesirable effects (p<0.01). CONCLUSIONS: The authors suggest a consistent tool to evaluate the impact of this surgical procedure on quality of life of patients. High satisfaction levels with upper blepharoplasty stood out. Keywords: Blepharoplasty; Quality of life; Patient satisfaction

Quality of life before surgery is a predictive factor for satisfaction among patients undergoing sympathectomy to treat hyperhidrosis

Purpose: The objective of this study was to evaluate the postoperative quality of life (QOL) experienced among a group of 1167 patients who underwent video-assisted thoracoscopic sympathectomy (VATS) to treat primary hyperhidrosis, as compared with the presurgical QOL. Methods: Between February 2002 and June 2007, 1167 patients who had undergone VATS were surveyed. The majority had presented with palmar hyperhidrosis (794 patients; 68%), while 340 (29%) had presented with axillary hyperhidrosis. Based on data obtained from the QOL protocol applied to all of the patients preoperatively, the patients were divided into two groups according to the level of their QOL: group 1 consisted of 312 patients (27%) with poor QOL and group 2 of 855 patients (73%) with very poor QOL. The same protocol was applied postoperatively, and five different levels of satisfaction were obtained. The same parameters were evaluated for both the palmar and the axillary hyperhidrosis subgroups. Results: The patients with very poor QOL had much better results in terms of improvement in QOL than did those with poor QOL ( P < .05). The same result was observed for both the palmar and. axillary hyperhidrosis subgroups (P < .05). Conclusion: The worse the preoperative QOL among patients undergoing sympathectomy to treat primary hyperhidrosis is, the better the postoperative improvement in QOL will be.

Respiratory Infection, Exposure to Mouse Allergen and Breastfeeding: Role in Recurrent Wheezing in Early Life

Background: Environmental factors may influence the development of allergen sensitization and asthma. The aim of this study was to evaluate the role of endotoxin and allergen exposure in early life as a risk factor for recurrent wheezing. Methods: One hundred and four infants from low-income families, at high risk of asthma, were enrolled at birth. Dust samples were collected from the bedding and bedroom floor within 6 months after birth. Recurrent wheezing was defined as 3 or more wheezing episodes in the past year. Endotoxin was determined by Limulus amebocyte lysate assay, and major indoor allergens were quantitated by ELISA in dust extracts. IgE antibodies were measured by ImmunoCAP at 30 months of age. Results: At 30 months, 51 of the 99 infants who completed the study (51.5%) had recurrent wheezing. Respiratory infection was strongly associated with recurrent wheezing (OR 6.67, 95% CI 1.96-22.72), whereas exclusive breastfeeding for at least 1 month was a protective factor (OR 0.09, 95% CI 0.01-0.51). Exposure to high levels of mouse allergen was more frequent among non-recurrent wheezers, approaching significance (OR 0.12, 95% CI 0.01-1.13; p=0.064). None of the children were sensitized to mouse. Sensitization to mite was found in 26/90 (28.8%) children, with no association with recurrent wheezing. Conclusion: Respiratory infection was strongly associated with recurrent wheezing in the first 30 months of life, in children at high risk of asthma, living in a socially deprived community in Brazil.

TAC3/TACR3 Mutations Reveal Preferential Activation of Gonadotropin-Releasing Hormone Release by Neurokinin B in Neonatal Life Followed by Reversal in Adulthood

Context: Mutations in TAC3 and TACR3 (encoding neurokinin B and its receptor) have been identified in Turkish patients with idiopathic hypogonadotropic hypogonadism (IHH), but broader populations have not yet been tested and genotype-phenotype correlations have not been established. Objective: A broad cohort of normosmic IHH probands was screened for mutations in TAC3/TACR3 to evaluate the prevalence of such mutations and define the genotype/phenotype relationships. Design and Setting: The study consisted of sequencing of TAC3/TACR3, in vitro functional assays, and neuroendocrine phenotyping conducted in tertiary care centers worldwide. Patients or Other Participants: 345 probands, 18 family members, and 292 controls were studied. Intervention: Reproductive phenotypes throughout reproductive life and before and after therapy were examined. Main Outcome Measure: Rare sequence variants in TAC3/TACR3 were detected. Results: In TACR3, 19 probands harbored 13 distinct coding sequence rare nucleotide variants [three nonsense mutations, six nonsynonymous, four synonymous (one predicted to affect splicing)]. In TAC3, one homozygous single base pair deletion was identified, resulting in complete loss of the neurokinin B decapeptide. Phenotypic information was available on 16 males and seven females with coding sequence variants in TACR3/TAC3. Of the 16 males, 15 had microphallus; none of the females had spontaneous thelarche. Seven of the 16 males and five of the seven females were assessed after discontinuation of therapy; six of the seven males and four of the five females demonstrated evidence for reversibility of their hypogonadotropism. Conclusions: Mutations in the neurokinin B pathway are relatively common as causes of hypogonadism. Although the neurokinin B pathway appears essential during early sexual development, its importance in sustaining the integrity of the hypothalamic-pituitary-gonadal axis appears attenuated over time.

GABAergic mediation of stress-induced secretion of corticosterone and oxytocin, but not prolactin, by the hypothalamic paraventricular nucleus

The hypothalamus-pituitary-adrenal axis (HPA) participates in mediating the response to stressful stimuli. Within the HPA, neurons in the medial parvocellular region of paraventricular nucleus (PVN) of the hypothalamus integrate excitatory and inhibitory signals triggering secretion of corticotropin-releasing hormone (CRH), the main secretagogue of adrenocorticotropic hormone (ACTH). Stressful situations alter CRH secretion as well as other hormones, including prolactin and oxytocin. Most inputs to the PVN are of local origin, half of which are GABAergic neurons, and both GABA-A and GABA-B receptors are present in the PVN. The objective of the present study was to investigate the role of GABA-A and GABA-B receptors in the PVN`s control of stress-induced corticosterone, oxytocin and prolactin secretion. Rats Were microinjected with saline or different doses (0.5, 5 and 50 pmol) of GABA-A (bicuculine) or GABA-B (phaclofen) antagonists in the PVN. Ten minutes later, they were subjected to a stressor (ether inhalation) and blood samples were collected 30 min before and 10, 30, 60, 90 and 120 min after the stressful stimulus to measure hormone levels by radioimmunoassay. Our results indicate that GABA acts in the PVN to inhibit stress-induced corticosterone secretion via both its receptor subtypes, especially GABA-B. In contrast, GABA in the PVN stimulates oxytocin secretion through GABA-B receptors and does not alter prolactin secretion. (C) 2008 Elsevier Inc. All rights reserved.

High levels of anxiety and depression have a negative effect on quality of life of women with chronic pelvic pain

Chronic pelvic pain (CPP) is a common and complex disease whose cause is often clinically inexplicable, with consequent difficulty in diagnosis and treatment. Patients with CPP have high levels of anxiety and depression, with a consequent impairment of their quality of life. The objective of this study was to determine the prevalence of anxiety and depression and their impact on the quality of life of women with CPP. A cross-sectional controlled study was conducted on 52 patients with CPP and 54 women without pain. Depression and anxiety were evaluated by the Hospital Anxiety and Depression Scale, and quality of life was evaluated by the World Health Organization Quality of life Whoqol-bref questionnaire. Data were analysed statistically by the Mann-Whitney U-test, the Fisher exact test, chi-square test and Spearman correlation test. The prevalence of anxiety was 73% and 37% in the CPP and control groups, respectively, and the prevalence of depression was 40% and 30% respectively. Significant differences between groups were observed in the physical, psychological and social domains. Patients with higher anxiety and depression scores present lower quality of life scores. The fact that DPC is a syndromic complex, many patients enter a chronic cycle of search for improvement of medical symptoms. The constant presence of pain may be responsible for affective changes in dynamics, family, social and sexual. Initially the person is facing the loss of a healthy body and active, to a state of dependence and limitations. In this study, patients with higher scores of anxiety and depression scores had lower quality of life and patients with lower scores of anxiety and depression had scores of quality of life. These results show that perhaps the depression and anxiety may be related to the negative impact on quality of life of these patients. In view of this association, we emphasise the importance of a specific approach to the treatment of anxiety and depression together with clinical treatment to improve the quality of life of these patients.

Cannabidiol Reduces the Anxiety Induced by Simulated Public Speaking in Treatment-Naive Social Phobia Patients

Generalized Social Anxiety Disorder (SAD) is one of the most common anxiety conditions with impairment in social life. Cannabidiol (CBD), one major non-psychotomimetic compound of the cannabis sativa plant, has shown anxiolytic effects both in humans and in animals. This preliminary study aimed to compare the effects of a simulation public speaking test (SPST) on healthy control (HC) patients and treatment-naive SAD patients who received a single dose of CBD or placebo. A total of 24 never-treated patients with SAD were allocated to receive either CBD (600 mg; n = 12) or placebo (placebo; n = 12) in a double-blind randomized design 1 h and a half before the test. The same number of HC (n = 12) performed the SPST without receiving any medication. Each volunteer participated in only one experimental session in a double-blind procedure. Subjective ratings on the Visual Analogue Mood Scale (VAMS) and Negative Self-Statement scale (SSPS-N) and physiological measures (blood pressure, heart rate, and skin conductance) were measured at six different time points during the SPST. The results were submitted to a repeated-measures analysis of variance. Pretreatment with CBD significantly reduced anxiety, cognitive impairment and discomfort in their speech performance, and significantly decreased alert in their anticipatory speech. The placebo group presented higher anxiety, cognitive impairment, discomfort, and alert levels when compared with the control group as assessed with the VAMS. The SSPS-N scores evidenced significant increases during the testing of placebo group that was almost abolished in the CBD group. No significant differences were observed between CBD and HC in SSPS-N scores or in the cognitive impairment, discomfort, and alert factors of VAMS. The increase in anxiety induced by the SPST on subjects with SAD was reduced with the use of CBD, resulting in a similar response as the HC.

Colostrum Ingested during the First Day of Life by Exclusively Breastfed Healthy Newborn Infants

Objective To determine the mass of colostrum ingested by exclusively breastfed newborn infants during the first 24 hours of extrauterine life. Study design Milk ingested during the first 24 hours of life by 90 healthy newborn infants was evaluated by use of a scale with high sensitivity. The masses were measured during 8-hour periods. Associations of the mass measured with prenatal and postnatal variables were tested. Results The mass of colostrum ingested was evaluated in 307 feedings, with 3.4 +/- 1 feedings recorded per 8-hour period of observation. Mean gain per feeding was 1.5 +/- 1.1 g. The daily mass of milk ingested by newborn infants was estimated at 15 +/- 11 g. This volume did not show a tendency to increase during the first 24 postnatal hours, nor was it related to perinatal or postnatal factors or to breastfeeding time. Conclusions During the first 24 hours of life newborns ingested 15 +/- 11 g of milk. (J Pediatr 2010; 156: 29-32).

Maternal Anxiety and Depression and Development of Prematurely Born Infants in the First Year of Life

The Purpose of this study was: (a) to assess and to compare anxiety and depression symptoms in mothers of preterm neonates during hospitalization in the Neonatal Intenive Care Unit, after discharge, and at the end of the infants` first year of life and (b) to assess the child`s development at 12 months of chronological corrected age (CCA). Thirty-six mothers, with no psychiatric antecedents assessed with the SCID-NP were evaluated by STAI and BDI The infants were assessed with Bayley-II Scales. There was a significant decrease in clinical symptoms of state-anxiety in mothers (p =.008). comparing the period during hospitalization and after discharge of the infants. Clinical symptoms of anxiety and depression were observed in 20% of the mothers at the end of the infants` first year of age. The majority of the infants exhibited normal development on Bayley-II at 12 months CCA: however. 25% of the infants displayed cognitive problems and 40% motor problems. The mothers` anxiety and depression symptoms decreased it the end of the first year of life of the pre-term infants and the children showed predominately normal development Lit this phase.

Exposure to maternal smoking during fetal life affects food preferences in adulthood independent of the effects of intrauterine growth restriction

Experimental animal studies have shown that nicotine exposure during gestation alters the expression of fetal hypothalamic neuropeptides involved in the control of appetite. We aimed to determine whether the exposure to maternal smoking during gestation in humans is associated with an altered feeding behavior of the adult offspring. A longitudinal prospective cohort study was conducted including all births from Ribeirao Preto (Sao Paulo, Brazil) between 1978 and 1979. At 24 years of age, a representative random sample was re-evaluated and divided into groups exposed (n = 424) or not (n = 1586) to maternal smoking during gestation. Feeding behavior was analyzed using a food frequency questionnaire. Covariance analysis was used for continuous data and the chi(2) test for categorical data. Results were adjusted for birth weight ratio, body mass index, gender, physical activity and smoking, as well as maternal and subjects` schooling. Individuals exposed to maternal smoking during gestation ate more carbohydrates than proteins (as per the carbohydrate-to-protein ratio) than non-exposed individuals. There were no differences in the consumption of the macronutrients themselves. We propose that this adverse fetal life event programs the individual`s physiology and metabolism persistently, leading to an altered feeding behavior that could contribute to the development of chronic diseases in the long term.

Validation of the Brazilian version of the quality of life scale for patients with Alzheimer`s disease and their caregivers (QOL-AD)

Quality of life (QOL) has been extensively studied in clinical trials and in research on chronic degenerative diseases and dementia. The aim of this study was to assess the reliability and construct validity of the Brazilian version of the QOL scale in Alzheimer`s disease (AD; QOL-AD). The QOL-AD was administered to 60 patients with mild or moderate AD and to their caregivers. The construct validation was accomplished through correlations amongst total scores of patients` and caregivers` reports on patients` quality of life (PQOL and C-PQOL, respectively), and data related to cognitive impairment, depressive symptoms, functional performance, behavioral disturbances and a generic instrument of quality of life (WHOQOL-brief), as well as correlation of total score of caregivers` reports on their own quality of life (CQOL) with the measurements cited above, QOL-AD patient reports, and depressive symptoms. The reliability was high for PQOL, C-PQOL, and CQOL versions (Cronbach`s alpha = 0.80, 0.83, and 0.86, respectively). We observed significant correlations in the construct validity of all three versions regarding the variables associated with the disease and also with WHOQOL-brief. The scale took, on average, six min for each version. The results indicate reliability and construct validity of the Brazilian version of the QOL-AD in the studied sample.
