Maternity ""Blues"" : Prevalence and Risk Factors

Objectives: estimate the Prevalence and track the risk factors associated with, Maternity blues (MB). Methods: a transversal study was performed with 113 women, on the tenth day of puerperium. The following instruments were used: Pitt Scale (1968), Stein (1980), Inventory for stressful life events by Holmes & Rahe (1967), and a questionnaire with sociodemographic and obstetric data. Results: the prevalence of MB was 32.7% according to the Stein scale. In the univariated analysis, civil status and tobacco use were associated with MB, Legally married women and nonsmokers showed a risk approximately 4 times lower of experiencing the problem. Conclusions: MB was very prevalent in this sample, Obstetricians must be aware of this condition which may be associated with postpartum depression.

Common mental disorders during pregnancy: prevalence and associated factors among low-income women in Sao Paulo, Brazil

To estimate the prevalence of common mental disorders (CMD) and factors associated with these disorders among pregnant women of low socio-economic status (SES) in Sao Paulo. We performed a cross-sectional study with 831 women in their 20th to 30th weeks of pregnancy, who were attending antenatal clinics in primary care in Sao Paulo, Brazil. CMD were assessed with the Clinical Interview Schedule-Revised. Crude and adjusted prevalence ratios and 95% CI were calculated to examine the association between CMD and exposure variables. The prevalence of CMD was 20.2% (95% CI 17.5 to 23.0). Age at current pregnancy and at first delivery, current obstetric complications, not having friends in the community, living in a crowded household, lower occupational status and history of previous psychiatric treatment were all independently associated with increased prevalence of CMD. CMD is highly prevalent among pregnant women of low SES seen in primary care settings in Sao Paulo. A combination of distal and proximal psychosocial factors increase the risk for CMD. Primary health care professionals need to be aware of how common CMD in such settings and properly trained to deal with CMD during pregnancy.

Osteoporotic Fractures in the Brazilian Community-Dwelling Elderly: Prevalence and Risk Factors

The risk of osteoporotic fractures is known to vary among populations. There are no studies analyzing concomitantly clinical, densitometric, and lab risk factors in miscigenated community-dwelling population of Brazil. A total of 1007 elderly subjects (600 women and 407 men) from Sao Paulo, were evaluated using a questionnaire that included risk factors for osteoporotic fractures. Bone mineral density (BMD) was measured by dual-energy X-ray absorptiometry at the hip and lumbar spine. Laboratory blood tests were also obtained. The prevalence of osteoporotic fractures was 13.2% (133 subjects), and the main fracture sites were distal forearm (6.0%), humerus (2.3%), femur (1.3%), and ribs (1.1%). Women had a higher prevalence (17.5%; 95% confidence interval [CI]: 14.6-20.6) than men (6.9%; 95% CI: 4.4-9.3) (p < 0.001). After adjusting for significant variables, logistic regression revealed that female gender (odds ratio [OR] = 2.7; 95% CI; 1.6-4.5; p < 0.001), current smoking (OR = 1.9; 95% CI: 1.2-3.3; p = 0.013), and the femoral neck T-score (OR = 0.7; 95% CI: 0.5-0.9; p = 0.001) remain significant risk factors for osteoporotic fractures in the community-dwelling elderly. Our findings identified that female gender, current smoking, and low hip BMD are independent risk factors for osteoporotic fractures.

Incidence and risk factors for agranulocytosis in Latin American countries - the Latin study

Purpose LATIN is a multinational case-control study designed to identify risk factors for agranulocytosis and to estimate the incidence rate of the disease in some Latin American countries. Methods Each study site in Brazil, Argentina and Mexico conducted an active search of agranulocytosis patients in hematology clinics and looked for possible associations with drug use. Results The overall incidence rate was 0.38 cases per 1 million inhabitant-years. Agranulocytosis patients more often took medications already associated with agranulocytosis than controls (p=0.01), mainly methimazole (OR 44.2, 95% CI 6.8 to infinity). The population attributable risk percentage (etiologic fraction) was 56%. The use of nutrient supplements was more frequent among patients than controls (p=0.03). Conclusions Agranulocytosis seems to be very rare in Latin America. The lower than expected number of cases identified during the study period precluded estimation of the risk associated to individual drugs, with the exception of methimazol. However, this is the longest series of agranulocytosis cases ever gathered in Latin America, and information on drug exposures was collected prospectively. The conclusion is that drug-induced agranulocytosis does not seem to be a major public health problem in the study regions.

Exclusive Breastfeeding in Southern Brazil: Prevalence and Associated Factors

Background: Worldwide strategies have been conducted in order to guarantee longer periods of exclusive breastfeeding for most children, especially those from developing countries. The evaluation of infant feeding practices and the identification of weaning risk factors are essential for public health policy planning. Methods: This cross-sectional study was carried out in Joinville, the biggest city of Santa Catarina State in the southern Brazilian region. The caregivers of children under 1 year of age were systematically selected for interview in previously drawn immunization units during the 2005 National Vaccination Campaign. A structured questionnaire was applied for collection of infant, maternal, and healthcare variables. A 24-hour food recall survey was included in order to evaluate infant feeding practices. Descriptive statistic analysis on breastfeeding prevalence and Poisson regression analysis of risk factors for discontinuing exclusive breastfeeding for infants up to 6 months of age were performed. Results: Caregivers of 1,470 infants were interviewed. The feeding inquiry showed an overall rate of breastfeeding of 72.5% and a frequency of exclusive breastfeeding of 43.7% and 53.9% among infants younger than 6 and 4 months of age, respectively. The findings associated with the interruption of exclusive breastfeeding for infants up to 6 months were: higher infant age (P < 0.001), pacifier use (P < 0.001), and lower maternal educational level (P = 0.013). Conclusions: In developing countries, specific strategies must be created for the delivery of information about breastfeeding and the effect of pacifier use, especially for less educated women.

Erectile Dysfunction and Correlated Factors in Brazilian Men Aged 18-40 years

Introduction. Few population-based studies in erectile dysfunction (ED) included subjects less than 40 years old and analyzed the several factors and consequences potentially associated with this condition. Aim. Evaluation of the prevalence of erectile dysfunction (ED) and associated factors in a sample of Brazilian men aged 18 to 40 years old. Methods. Cross-sectional study in which subjects were contacted in public places of 18 major Brazilian cities and interviewed using an anonymous questionnaire. Survey data were submitted to chi-squared, student`s t-test and logistic regression analyses. Main Outcome Measures. The data were collected by means of a self-administered questionnaire with 87 questions about sociodemographic variables, general health, habits and lifestyle-related factors, sexual behavior and sexual difficulties, including ED which was assessed by a single question. Results. Prevalence of ED in 1,947 men was 35.0% (73.7% mild, 26.3% moderate/complete). Greater frequency of ED was seen in subjects that never had information about sex, experienced difficulties in the beginning of sexual life and have never masturbated. ED was associated to lower level of education, but not to race, sexual orientation, employment or marital status. Also, no association was found between ED and smoking, alcoholism, obesity, sedentary life, diabetes, hypertension, cardiovascular disease, hyperlipidemia, depression or anxiety. ED caused negative impact in men`s self-esteem, interpersonal relationships, work and leisure activities, and in sexual life satisfaction. Less than 10% of men with ED had received medical treatment for this problem. Conclusions. Prevalence of ED in this young population was high, mostly of mild severity. Low education and psychosocial problems were associated to ED and, due probably to the sample subjects` young age, no association was found with organic problems. Measures in the fields of education and psychosocial difficulties prevention would have a positive impact in the control of erectile dysfunction in the young population. Martins FG, and Abdo CHN.

Epidemiology and risk factors for osteonecrosis of the jaw in cancer patients

Osteonecrosis of the jaw (ONJ), previously an entity associated with radiation therapy to the head and neck, has been observed in patients treated with bisphosphonates. Patients with metastatic breast cancer and myelomatous bone disease, commonly treated with high-potency nitrogen-containing bisphosphonates for a prolonged period of time, have the greatest risk of ONJ development. The reported frequency of ONJ ranges from 0.6% to 6.2% in breast cancer and from 1.7% to 15% in patients with multiple myeloma. Osteonecrosis of the jaw has also been observed in patients with other cancers such as prostate cancer and in benign bone disorders such as osteoporosis and Paget`s disease in which the incidence is low. Risk factors associated with the development of ONJ include dental extractions, length of bisphosphonate treatment, and the type of bisphosphonate used. In this review, we summarize the reported incidence and risk factors associated with ONJ.

Twelve-Month Prevalence of and Risk Factors for Suicide Attempts in the World Health Organization World Mental Health Surveys

Objective: Although suicide is a leading cause of death worldwide, clinicians and researchers lack a data-driven method to assess the risk of suicide attempts. This study reports the results of an analysis of a large cross-national epidemiologic survey database that estimates the 12-month prevalence of suicidal behaviors, identifies risk factors for suicide attempts, and combines these factors to create a risk index for 12-month suicide attempts separately for developed and developing countries. Method: Data come from the World Health Organization (WHO) World Mental Health (WMH) Surveys (conducted 2001-2007), in which 108,705 adults from 21 countries were interviewed using the WHO Composite International Diagnostic Interview. The survey assessed suicidal behaviors and potential risk factors across multiple domains, including socio-demographic characteristics, parent psychopathology, childhood adversities, DSM-IV disorders, and history of suicidal behavior. Results: Twelve-month prevalence estimates of suicide ideation, plans, and attempts are 2.0%, 0.6%, and 0.3%, respectively, for developed countries and 2.1%, 0.7%, and 0.4%, respectively, for developing countries. Risk factors for suicidal behaviors in both developed and developing countries include female sex, younger age, lower education and income, unmarried status, unemployment, parent psychopathology, childhood adversities, and presence of diverse 12-month DSM-IV mental disorders. Combining risk factors from multiple domains produced risk indices that accurately predicted 12-month suicide attempts in both developed and developing countries (area under the receiver operating characteristic curve = 0.74-0.80). Conclusions: Suicidal behaviors occur at similar rates in both developed and developing countries. Risk indices assessing multiple domains can predict suicide attempts with fairly good accuracy and may be useful in aiding clinicians in the prediction of these behaviors.

Clinically Significant Depressive Symptoms and Associated Factors in Community Elderly Subjects From Sao Paulo, Brazil

Objectives: To determine the frequency of clinically significant depressive symptoms (CSDS) in a community sample of Brazilian elderly and to assess their relationship with sociodemographic factors, cognitive and functional impairment (CFI), and clinical diseases. Design: Cross-sectional study of a community-based sample of elderly subjects. Setting: City of Sao Paulo, State of Sao Paulo, Brazil. Participants: A total of 1,563 elderly subjects aged 60 years or older. Measurements: A 10-item scale for screening of depressive symptoms in elderly people (D-10), the Mini Mental State Examination, the Fuld Object Memory Evaluation, the Informant Questionnaire on Cognitive Decline in the Elderly, the Bayer Activities of Daily Living Scale, and a sociodemographic and clinical questionnaire. Results: The frequency of CSDS was 13.0%. Univariate analysis identified independent factors associated with these symptoms in our sample. Logistic regression analysis indicated that being female, brown skinned, previously depressed, having CFI, using psychotropics, and not practicing physical exercise were related to CSDS. On the other hand, being older, clinically sick, employed, or married were not associated with CSDS. Conclusions: Consistent with previous reports, female gender, lack of physical activity, and CFI were significantly associated with higher frequencies of CSDS. Further investigations are necessary to clarify the occurrence of depression and possible modifiable factors in developing countries such as Brazil. (Am J Geriatr Psychiatry 2009; 17: 582-590)

Cardiovascular Risk and Clinical Factors in Athletes: 10 Years of Evaluation

DE MATOS, L. D. N. J., N. D. A. O. CALDEIRA, P. D. S. PERLINGEIRO, I. L. G. DOS SANTOS, C. E. NEGRAO and L. F. AZEVEDO. Cardiovascular Risk and Clinical Factors in Athletes: 10 Years of Evaluation. Med. Sci. Sports Exerc., Vol. 43, No. 6, pp. 943-950, 2011. Purpose: Preparticipation screening in athletes is a very current but controversial theme. Part of this controversy is due to the cost benefit, especially when the screening is merely used as a prevention of sudden cardiac death caused by rare and hereditary diseases. The purpose of this study was to describe the prevalence of preexisting diseases, cardiovascular risk factor for cardiovascular diseases development, and hematological profile in a population of amateur and professional athletes. Methods: Data of 623 athletes (529 men and 94 women), aged 13-77 yr, were analyzed to detect preexisting diseases. The variables total cholesterol, LDL, HDL, triglycerides, fasting glucose, body mass index, hemoglobin, hematocrit, and ferritin were analyzed in two groups according to age, that is, younger and older 35 yr old, and their prevalence (%) and distribution in quartiles were presented. chi(2) test and Pearson product-moment correlation coefficients between variables were applied, and P < 0.05 was adopted for significance. Results: Hypertension was the most prevalent preexisting diseases, although the data showed low prevalence of cardiomyopathy. Cardiovascular risk factors were prevalent in both genders. There were positive correlations between cardiovascular risk factors and age and between body mass index and lipid levels in male athletes. Also, there was a high prevalence of low ferritin levels for women, with positive correlation between the levels of hemoglobin and ferritin. Conclusions: In the present study, hypertension was the most prevalent diagnosed disease, and cardiovascular risk factors showed important prevalence, especially in athletes older than 35 yr. Although physical training represents a cardioprotective factor to the onset of cardiovascular disease, it does not exclude the prevalence of risk factors and diseases in athletes.

Neurosyphilis in HIV-infected patients: Clinical manifestations, serum venereal disease research laboratory titers, and associated factors to symptomatic neurosyphilis

Goal: To describe clinical and laboratory features of human immunodeficiency infection (HIV)-infected patients with neurosyphilis. Study Design: Retrospective study of 27 consecutive cases of HIV-infected patients with a positive Venereal Disease Research Laboratory (VDRL) in cerebrospinal fluid (CSF). Results: Median of age was 36 years and 89% were men. Ten (37%) patients had previous nonneurologic syphilis treatment. At the time of neurosyphilis diagnosis, 10 (37%) patients had early syphilis, and 6 of them were neurologically asymptomatic. Nine (33%) patients had symptomatic neurosyphilis. Twenty-six (96%) patients were classified with early neurosyphilis. The medians of serum VDRL and CD4(+) T cell counts were 1:128 and 182 cell/mu L, respectively. Twenty five (93%) patients presented serum VDRL titers >= 1:16. Five of 6 patients with early syphilis and asymptomatic neurosyphilis, presented serum VDRL >= 1:16. Symptomatic patients showed lower CD4(+) T cell counts (59 cell/mu L vs. 208 cell/mu L, P = 0.03) and higher protein concentration on CSF (118 mg/dL vs. 39 mg/dL, P <0.001) than asymptomatic patients. Conclusions: Most patients had early and asymptomatic neurosyphilis, and more than one third had early syphilis. Patients with symptomatic neurosyphilis showed lower CD4(+) T cell counts and higher protein concentration on CSF than those asymptomatic. Most patients had serum VDRL titers >= 1:16, regardless of syphilis stage.

Fatigue in amyotrophic lateral sclerosis: Frequency and associated factors

We aimed to quantify fatigue frequency and evolution in amyotrophic lateral sclerosis (ALS), and to correlate fatigue with factors such as age, sex, educational level, disease duration, functionality, quality of life, dyspnoea, depression and sleepiness. Sixty ALS patients (test group: TG) selected by El Escorial criteria and 60 normal individuals (control group: CG) matched according to sex and age, were followed every three months, during 9 months, by means of self-report scales: Fatigue Assessment Instrument (Fatigue Severity Scale plus three qualitative subscales); ALS Functional Rating Scale; McGill Quality of Life Questionnaire; dyspnoea analogical scale; Beck Depression Inventory and Epworth Sleepiness Scale. Fatigue was reported by 83% of TG (median: 3.6, interquartile range 1.5-5.4), compared with 20% of CG (median: 1, 1 - 1), and was significantly greater in the TG (p < 0.001, Mann-Whitney test). Fatigue severity increased by the ninth month of the study (p=0.0008, Friedman, Muller-Dunn post test). There was no correlation between fatigue and other parameters, except for an inverse correlation with age at disease onset (p=0.0395, Spearman rank correlation). In conclusion, fatigue was frequent in ALS, greater in the youngest patients and worsened during follow-up. Possibly, ALS related fatigue is an independent factor, which deserves individualized approach and treatment.
