Introduction: The physical activity and adequate food plays a key role in improving health and the control of diseases. Objective: This paper aims at determining the nutritional state through antropometric measures, socioeconomic level, the most common illnesses and type of physical activity, beyond food consumption and the place where meals are taken, of under-graduate students of the Nutrition course in UFPE. Methods: The sample is constituted of 68 female students, of different periods and at ages between 18 and 27 years old. The process of selection of the sample was for convenience. The students voluntarily participated and answered three questionnaires, respectively, on their socioeconomic level (income of the family) and possible illnesses they had, measures of the cutaneous folds and type of practiced physical activity; register of consumed foods and local where the meals were carried. Statistical analysis was performed by absolute frequency, percentage, average and standard deviation. The margin of error used in the testing employees was 5%. Results: In relation to the incomes, they had predominated above three minimum wages (86%), the parents have a predominant role in the expenditure of their study (46%), followed by the father (24%), mother (9%), husband (4%), other responsible ones (10%); 7% did not give information. The most common illnesses were: allergic rinite, tonsilitis, sleeplessness and intestinal constipation. The weight, the height, the index of body mass and the relation waist hip of the students were within normal standards. The abdominal circumference varied only in 2.57 cm between the studied age range. In relation to the practice of physical activities, 67% were sedentary, 20% practiced light activity and 13% moderate. In relation to where the meals are had, breakfast, in its majority (76%), was carried at home, followed by supper (56%), while lunch (41%) and snack 1 (34%), at University. Among the pupils who did not inform the place where they had their meals there was a high percentage for the big meals and a small one for the minor ones. The main kinds of consumed meals were breakfast, lunch and supper (98%). For the small meals, the values were: snack 1 (54%), snack 2 (61%), snack 3 (45%). The analysis of food consumption for three days disclosed ingestion of energy with deficit of 21% in relation to the recommended one (p < 0.001); the macro-nutrients showed percentages within the standards; the intake of fiber (11.8 g/day) was less than recommended (p < 0.001). Meat, eggs and cereals were ingested daily (for about 80%); vegetables (40%), legumes, fruits and candies (25% 30%), around four or six days a week. Roots and tubercles, salty, embedded and non alcoholic drinks were consumed from one to three days weekly (70%). Animal guts were not consumed by 50% of the studied population. Conclusions: Having analyzed all this, the studied students need to modify their food habits, acquiring knowledge on the importance of a balanced diet, as well as the practice of physical activity systematically, to prevent illnesses and attain a better quality of life.

- Abstract
This study aimed to compare cardiopulmonary fitness and endothelial function 6 months after hospital diagnosis in a sample mainly comprising immunocompromised patients with confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection versus noninfected controls. Youth ( n = 30; age: 14 yr; 60% females) with confirmed SARS-CoV-2 seen in a tertiary hospital of Sao Paulo, Brazil, were matched by propensity score based on BMI, age, sex, and pre-existing diseases with a control group who had not been tested positive for SARS-CoV-2 infection ( n = 30; age: 15 yr; 50% females). Cardiopulmonary fitness (by means of a cardiopulmonary exercise test: CPET) and brachial flow-mediated dilation (%b-FMD) were assessed 3-6 mo after diagnosis. Patients were matched by propensity score based on BMI, age, sex and pre-existing diseases, if any, with a control group who had not been tested positive for SARS-CoV-2. Compared with controls, patients with COVID-19 showed reduced ventilatory anaerobic threshold (VAT) and peak exercise time and minute ventilation/maximum voluntary ventilation (V̇e/MVV) (all P < 0.01). Brachial endothelial function variables were all adjusted for body surface area (BSA). Patients with COVID-19 had decreased %b-FMD (3.6 vs. 5.4; P = 0.03) mean and positive flow ( P = 0.02 and P = 0.03, respectively) versus controls. Adjusted linear regression models exploring associations between CPET variables, %b-FMD and the potential predictors post-COVID-19 syndrome, number of symptoms, hospitalization, and COVID severity did not detect significant associations, except for total shear rate in hospitalization (coefficient: -65.07 [95%CI -119.5;-10.5], P = 0.02). Immunocompromised and previously healthy children and adolescents with COVID-19 presented with impaired exercise capacity and endothelial dysfunction when compared with their noninfected counterparts, but the mechanisms remain unknown. NEW & NOTEWORTHY COVID-19 appeared to impair recovery of exercise capacity and endothelial function in a sample mainly comprising immunocompromised patients, but the mechanisms are unknown. These findings support the need for preventive measures against COVID-19 in this vulnerable population and suggest the necessity of proper monitoring and treatment for these patients.

- Abstract
Background: The frequency of antibodies in autoimmune encephalitis (AIE) may vary in different populations, however, data from developing countries are lacking. To describe the clinical profile of AIE in Brazil, and to evaluate seasonality and predictors of AIE in adult and pediatric patients., Methods: We evaluated patients with possible AIE from 17 centers of the Brazilian Autoimmune Encephalitis Network (BrAIN) between 2018 and 2022. CSF and serum were tested with TBAs and CBAs. Data on clinical presentation, complementary investigation, and treatment were compiled. Seasonality and predictors of AIE in adult and pediatric populations were analyzed., Results: Of the 564 patients, 145 (25.7%) were confirmed as seropositive, 69 (12.23%) were seronegative according to Graus, and 58% received immunotherapy. The median delay to diagnosis confirmation was 5.97 ± 10.3 months. No seasonality variation was observed after 55 months of enrolment. The following antibodies were found: anti-NMDAR (n=79, 54%), anti-MOG (n=14, 9%), anti-LGI1(n=12, 8%), anti-GAD (n=11, 7%), anti-GlyR (n=7, 4%), anti-Caspr2 (n=6, 4%), anti-AMPAR (n=4, 2%), anti-GABA-BR (n=4, 2%), anti-GABA-AR (n=2, 1%), anti-IgLON5 (n=1, 1%), and others (n=5, 3%). Predictors of seropositive AIE in the pediatric population (n=42) were decreased level of consciousness (p=0.04), and chorea (p=0.002). Among adults (n=103), predictors of seropositive AIE were movement disorders (p=0.0001), seizures (p=0.0001), autonomic instability (p=0.026), and memory impairment (p=0.001)., Conclusion: Most common antibodies in Brazilian patients are anti-NMDAR, followed by anti-MOG and anti-LGI1. Only 26% of the possible AIE patients harbor antibodies, and 12% were seronegative AIE. Patients had a 6-month delay in diagnosis and no seasonality was found. Findings highlight the barriers to treating AIE in developing countries and indicate an opportunity for cost-effect analysis. In this scenario, some clinical manifestations help predict seropositive AIE such as decreased level of consciousness, chorea, and dystonia among children, and movement disorders and memory impairment among adults., Competing Interests: Authors AD and LA were employed by Fleury Group.

- Abstract
Objective: The aim of this study was to assess the prevalence of orofacial manifestations in a Brazilian cohort of people living with HIV/AIDS (PLWHIV) using long-term combined antiretroviral therapy (cART) and to correlate the presence of these manifestations with clinical and laboratory characteristics., Study Design: A cross-sectional observational study evaluated 101 Brazilian PLWHIV. Demographic characteristics, medical history, and laboratory data were collected. Physical examination and measurement of stimulated salivary flow were performed., Results: The study included 101 participants who were mainly male (61%) and White (73%), with an average age of 48 years, using long-term cART. The most common oral manifestations were facial lipoatrophy (33%), xerostomia (30%), and salivary gland enlargement (12%). Facial lipoatrophy was linked to a longer duration of cART use (P = .002), whereas hairy leukoplakia was linked to a detectable viral load (P = .031). The salivary flow of <0.7 mL/min was associated with an HIV infection time >20 years (P = .023)., Conclusions: People living with HIV/AIDS who use cART often experience facial lipoatrophy, xerostomia, and bilateral enlargement of the parotid glands. Although opportunistic infections and malignant neoplasms are not frequent occurrences, they can still arise., Competing Interests: Declaration of Interest None., (Copyright © 2023 Elsevier Inc.

- Abstract
Introduction: The goal of asthma therapy is asthma control. As a chronic disease, asthma may cause considerable physical, emotional and social restrictions impacting quality of life. The aim of this study was to analyze control of asthma symptoms in an outpatient setting in Brazil and its impact on quality of life., Methods: A pilot cross-sectional study was performed in two public centers in the metropolitan region of São Paulo, Brazil. Control of asthma symptoms was assessed according to GINA guidelines, and quality of life was analyzed by the Mini Quality of Life Questionnaire (mini-AQLQ)., Results: A total of 47 adult patients with asthma were analyzed. Asthma was controlled in 8 patients (17.0%), partially controlled in 26 patients (55.3%) and uncontrolled in 13 patients (27.7%). Patients with controlled asthma showed better mini-AQLQ scores (4.99 ± 1.10) as compared to those with partly controlled (3.66 ± 1.10) and uncontrolled asthma (2.59 ± 0.64; p < 0.001 for both). Most patients (85.1%) were taking inhaled corticosteroids (ICS) and long-acting bronchodilators (LABA) as controller treatment., Conclusions: Better asthma control had a positive impact on Health-Related Quality of Life (HRQoL) contributing to a better disease management. Few patients reached full asthma control in our specialty ambulatory center, suggesting further initiatives are required to improve the quality of asthma care in Brazil.

- Abstract
The Brazilian Amazon has high rates of snakebite envenomings (SBEs), with ∼90% caused by Bothrops atrox. Envenomings by this species can trigger local and systemic effects, such as acute kidney injury (AKI). Our aim was to identify predictors of AKI in Bothrops SBEs in patients from Manaus, Western Brazilian Amazon. A total of 127 patients were enrolled, with a predominance of men between 16 and 45 years old from rural areas. Of the 127 patients, 38.6% developed AKI, with 61.2% presenting stage I, 34.7% presenting stage II and 4.1% presenting stage III severity. The age groups 0-10 years and ≥60 years presented a significantly higher frequency of AKI compared to the 11-40 years group. Moderate/severe edema in the affeccted limb was significantly associated with lower risk of AKI [p = 0.01; OR = 0.11 (95%CI 0.02-0.53)]. Nausea [p = 0.01; OR = 54.44 (95%CI = 3.26-909.27)] and high blood urea levels [p = 0.01; OR = 5.38 (95%CI = 2.12-13.66)] were risk factors for AKI. There was a significant positive correlation between circulating venom levels and the highest creatinine serum values during the hospital stay (p = 0.03) and with the difference between the maximum creatinine levels and the creatinine levels on admission (p = 0.02). A positive correlation between serum venom concentrations and creatinine levels suggests a direct or indirect dose-dependent participation of the venom toxins in the pathogenesis of AKI., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

- Abstract
Objective: The purpose of this study was to describe a detailed investigation of craniofacial and dental characteristics in a group of Brazilian Rubinstein-Taybi syndrome (RSTS) patients., Methods and Results: Thirteen RSTS patients treated in a special care dental clinic after 10 years were studied. Panoramic radiographs were obtained from all patients, and cephalometric analysis was performed in eight patients. Five male and eight white female patients with a median age of 11.7 years were analyzed. All the RSTS patients were mouth breathers and presented malocclusion, transverse hypoplastic maxilla, nine subjects (9/13; 69.2%) had posterior crossbite, and eight (61.53%) exhibited talon cusps. Most patients presented class II skeletal pattern and were brachycephalic. Regarding systemic disorders, one patient (7.69%) reported seizure episodes during childhood, and four patients (30.76%) presented heart valve disorders. All patients presented reduced attention span, low intolerance to dental interventions, impulsiveness, and irritability., Conclusions: Since RSTS exhibits oral and skeletal changes, early dental treatment is essential for these patients. Dentists must be aware of medical problems related to heart disease and persist in conditioning techniques to obtain cooperation and avoid dental care under general anesthesia., (© 2021 Special Care Dentistry Association and Wiley Periodicals LLC.)

- Abstract
Purpose: To develop and validate a chest cavity simulator for teaching video-assited thoracic surgery (VATS)., Methods: The first phase of the study consisted of developing a chest cavity simulator. A quasi-experimental study was performed in the second phase, and 25 surgeons and residents participated in a three-stage pulmonary suture experiment. The videos were recorded and timed. Generalized linear regression models for repeated measures were used to analyze the outcome change over time., Results: The chest cavity simulator consists of a console simulating the left hemithorax. Among the participants, 96% rated the design, visual aspect, positioning ergonomics, and triangulation of the portals as very good or excellent (face validity). There was a decrease in suturing time in step 1 from 435.7 ± 105 to 355.6 ± 76.8 seconds compared to step 3 (p = 0.001). The evaluation of the simulation effectiveness and performance (content validity) was rated as very good or excellent by 96% ofparticipants. The most experienced surgeon showed significant reduction in procedure time (p = 0.021) (construct validity)., Conclusions: The thoracic cavity simulator is realistic, showing content and construct validity, and can be used in VATS training. The simulation model allowed skill gain in the endoscopic suture.

- Abstract
Objective: To analyse the coping strategies of family members of patients admitted to intensive care units., Design: A cross-sectional study developed with 70 relatives of patients admitted to the intensive care unit., Setting: An adult intensive care unit at a university hospital in Brazil., Main Outcome Measures: Coping strategies were identified by the Folkman and Lazarus Inventory of Coping Strategies and statistically compared to the sociodemographic data of family members and patients' clinical data., Results: Coping strategies focused on emotion were the most used, especially those attributed to the escape-avoidance factor. There was a significant association (p < 0.05) between women and the use of adaptive strategies focused on the problem; less education and lower income with maladaptive strategies focused on emotion; second-degree relatives and the positive reassessment factor; participants involved in religious activities and the social support factor. Regarding the clinical variables, patients admitted to the intensive care unit for more than seven days showed an association (p < 0.05) with the social support factor., Conclusion: Family members used adaptive coping strategies more focused on emotion. Additionally, the lower the educational and economic levels, the greater the use of maladaptive strategies focused on emotion., (Copyright © 2020. Published by Elsevier Ltd.)

- Abstract
Zika virus (ZIKV) was first discovered in 1947 in Uganda but was not considered a public health threat until 2007 when it found to be the source of epidemic activity in Asia. Epidemic activity spread to Brazil in 2014 and continued to spread throughout the tropical and subtropical regions of the Americas. Despite ZIKV being zoonotic in origin, information about transmission, or even exposure of non-human vertebrates and mosquitoes to ZIKV in the Americas, is lacking. Accordingly, from February 2017 to March 2018, we sought evidence of sylvatic ZIKV transmission by sampling whole blood from approximately 2000 domestic and wild vertebrates of over 100 species in West-Central Brazil within the active human ZIKV transmission area. In addition, we collected over 24,300 mosquitoes of at least 17 genera and 62 species. We screened whole blood samples and mosquito pools for ZIKV RNA using pan-flavivirus primers in a real-time reverse-transcription polymerase chain reaction (RT-PCR) in a SYBR Green platform. Positives were confirmed using ZIKV-specific envelope gene real-time RT-PCR and nucleotide sequencing. Of the 2068 vertebrates tested, none were ZIKV positive. Of the 23,315 non-engorged mosquitoes consolidated into 1503 pools tested, 22 (1.5%) with full data available showed some degree of homology to insect-specific flaviviruses. To identify previous exposure to ZIKV, 1498 plasma samples representing 62 species of domestic and sylvatic vertebrates were tested for ZIKV-neutralizing antibodies by plaque reduction neutralization test (PRNT
90 ). From these, 23 (1.5%) of seven species were seropositive for ZIKV and negative for dengue virus serotype 2, yellow fever virus, and West Nile virus, suggesting potential monotypic reaction for ZIKV. Results presented here suggest no active transmission of ZIKV in non-human vertebrate populations or in alternative vector candidates, but suggest that vertebrates around human populations have indeed been exposed to ZIKV in West-Central Brazil.- Published

- Abstract
Objective: To investigate the histological subtypes and mutational profiles of non-small cell lung cancer in Brazil, looking for correlations among histological subtypes, expression of anaplastic lymphoma kinase (ALK), EGFR mutation status, and programmed death-ligand 1 (PD-L1) expression., Methods: We evaluated 173 specimens obtained from patients with lung adenocarcinoma in northeastern Brazil. Expression of PD-L1 and ALK was evaluated by immunohistochemistry; EGFR mutation status was evaluated by sequencing. We categorized the histological subtypes in accordance with the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society classification., Results: The most common histological subtypes of lung adenocarcinoma were solid predominant (in 46.8%), acinar predominant (in 37.0%), and lepidic predominant (in 9.8%). ALK expression was detected in 10.4% of the samples, and 22.0% of the tumors harbored EGFR mutations. The most common EGFR mutation was an exon 21 L858R point mutation (in 45.5%), followed by an exon 19 deletion (in 36.3%). The tumor proportion score for PD-L1 expression was ≥ 50% in 18.2% of the samples, 1-49% in 32.7%, and 0% in 49.5%. The solid predominant subtype was significantly associated with wild-type EGFR status (p = 0.047). Positivity for PD-L1 expression was not found to be significantly associated with ALK expression or EGFR mutation status., Conclusions: Our results suggest that the molecular profile of non-small cell lung cancer in northeastern Brazil differs from those of populations in other regions of the country, with ALK positivity being higher than the other biomarkers. Further studies including clinical and genetic information are required to confirm these differences, as well as studies focusing on populations living in different areas of the country.

- Abstract
Objective: The present study translated and adapted the Brazilian version of the Patient-Determined Disease Steps (PDDS) scale and tested its validity and reproducibility in Brazilian persons with multiple sclerosis (MS)., Methods: The PDDS underwent translation and back-translation procedures for producing a Brazilian Portuguese version of the PDDS (PDDS/BR). Sixty-three patients with MS (48 females) completed the PDDS/BR and underwent a neurological examination for generation of Expanded Disability Status Scale (EDSS) scores. Participants further performed the following tests: Timed 25-Foot Walk (T25FW), Timed Up and Go (TUG), six-minute walk test (6MWT), Nine Hole Peg (9HPT), and Symbol Digit Modalities Test (SDMT). Construct validity of PDDS/BR scores was determined by Spearman correlation with EDSS, and comparison of correlations between PDDS/BR and EDSS with the functional tests. We examined overall correct classification of disability categories (i.e., mild, moderate, or severe disability) by the PDDS/BR in relation to the EDSS. Test-retest reproducibility of PDDS/BR scores was examined in a subsample of 31 participants after 15 days., Results: There was a strong relationship between the PDDS/BR and EDSS scores (ρ = 0.723, p < 0.05). The correlations with TUG, T25FW, 6MWT, and 9HPT were comparable for the PDDS/BR and EDSS scores. Overall correct classification of disability categories by the PDDS/BR was 79.3%. Results indicated excellent test-retest reproducibility for the PDDS/BR (Intraclass Correlation Coefficient= 0.911, 95% CI: 0.685-0.918)., Conclusion: The PDDS/BR scores provide a valid and reliable assessment of mobility disability and may be used by researchers and neurologists to assess disability status in Brazilians with MS., (Copyright © 2019.

- Abstract
Escherichia coli are gut microbiota bacteria that can cause disease in some humans and other animals, including dogs and cats that humans often keep as pets. Diarrheagenic E. coli (DEC) strains are classified into six categories: enteropathogenic (EPEC), enterotoxigenic (ETEC), Shiga toxin-producing (STEC), enteroinvasive (EIEC), enteroaggregative (EAEC), and diffuse-adhering E. coli (DAEC). In this study 144 and 163 E. coli colonies were isolated from the fecal samples of 50 dogs and 50 cats, respectively, with and without diarrhea from a Veterinary Hospital (clinical isolates). The virulence factors were determined using multiplex Polymerase Chain Reaction. Adherence assays, antibacterial susceptibility and serotyping (somatic or flagellar antigens) were performed on DEC isolates. We found 25 (17.4%) and 4 (2.5%) DEC strains isolated from dogs and cats, respectively. Only the EPEC and EAEC pathotypes were found in both animals. Meanwhile, genes from other pathotypes (STEC, EIEC, and ETEC) were not found in these clinical isolates. All of the DEC strains showed mannose-resistant adherence to HEp-2 and HeLa cells, and aggregative adherence was predominant in these isolates. Multiresistant strains to antimicrobials were found in most DEC strains including usual and unusual antimicrobials in veterinary practices. The serotypes of these DEC isolates were variable. The ONT serotype was predominant in these isolates. Some serotypes found in our study were described to human DEC. Here, we demonstrate that pets carry virulent DEC genes, which are mainly strains of EPECs and EAECs. The presence of these virulence factors in isolates from animals without diarrhea suggests that pets can act as a reservoir for human infection., (Copyright © 2013 Elsevier B.V. All rights reserved.)

- Abstract
The goal of this study was to evaluate the morphometric variation of laelapine populations (Acari, Mesostigmata) associated with neotropical oryzomyine rodents at different geographic localities in Brazil. Three nominal mite species were selected for study, all infesting the pelage of small mammals at different localities in Rio de Janeiro, Espírito Santo, Bahia, and the Federal District, Brazil. To analyse morphometric characteristics, thirty-seven morphological characters distributed across the whole body of each specimen were measured. We use the Analysis of Principal Components, extracting the three first axes and projecting each mite in these axes. Major species level changes in the taxonomy of the host mammals allows an independent examination of morphometric variation of mites infesting a set of distinctly different host species at different geographic localities. Gigantolaelaps vitzthumi and Laelaps differens are associated with oryzomyine rodents of the genus Cerradomys, and consistently showed a tendency to cluster by host phylogeny. Laelaps manguinhosi associated with Nectomys rattus in central Brazil is morphometrically distinct from mites infesting N. squamipes in the coastal restingas of Rio de Janeiro and Espírito Santo. The results obtained here indicate that laelapine mite populations can vary among geographic areas and among phylogenetically related host species. Clearly, the study of these mites at the population level can be an important tool for clarifying the taxonomy of both mites and hosts.

- Abstract
Objective: Verify the association between genital prolapse, other risk factors and a polymorphism in exon 31 of the collagen III-a1 gene (COL3A1)., Setting: The etiology of genital prolapse is multifactorial, and genetic defects have been proposed. Also, there is evidence that changes in collagen may be responsible for defects in pelvic floor support. The exon 31 polymorphism results in structural changes in the triple helical of the collagen and appears to lead to abnormal synthesis of type III collagen., Design: Basic science study., Population: The studied group consisted of 107 patients with stage III and IV genital prolapse (POP-Q). The control group included 209 women with stage 0 and I prolapse., Methods: After extracting genomic DNA from the peripheral blood, the exon 31 COL3A1 polymorphism was typed by restriction fragment length polymorphism analysis., Main Outcome Measures: Association between genital prolapse and exon 31 COL3A1 polymorphism., Results: No statistically significant differences in genotype and allele frequencies were found between cases and controls (P = 0.75 and 0.66, respectively). Multiple logistic regression analyses identified age (OR = 1.05; 95%CI = 1.01-1.10), BMI (OR = 1.09; 95%CI = 1.01-1.17), presence of at least one vaginal delivery (OR = 7.22; 95%CI = 1.84-28.27), positive family history of POP (OR = 2.27; 95%CI = 1.05-4.93) and a macrosomic foetus (OR = 2.91; 95%CI = 1.24-6.79) as independent risk factors for genital prolapse. In contrast, the number of caesarean deliveries was found to be an independent protective factor (OR = 0.43; 95%CI = 0.24-0.78)., Conclusions: The type III collagen exon 31 polymorphism is not a risk factor for pelvic genital prolapse in this sample., (Copyright © 2011 Wiley-Liss, Inc.)

- Abstract
Objective: to determine the level of awareness regarding nonsteroidal anti-inflammatory drugs (NSAIDs) and the prevalence and reasons for their consumption among athletes competing at the 2008 Brazil Ironman Triathlon (3.8 km swim, 180 km cycle and 42.2 km run)., Design: survey study., Setting: 2008 Brazil Ironman Triathlon, Florianópolis, Brazil, May 2008., Participants: 327 Of the 1250 athletes competing at the 2008 Brazil Ironman Triathlon were enrolled in the study., Main Outcome Measures: athletes answered a questionnaire about NSAID effects, side effects and consumption at the bike checkout or awards lunch., Results: 196 (59.9%) Athletes reported using NSAIDs in the previous 3 months; of these, 25.5% (n=50), 17.9% (n=35) and 47.4% (n=93) consumed NSAIDs the day before, immediately before and during the race, respectively. Among NSAID users, 48.5% (n=95) consumed them without medical prescription. The main reason given for NSAID consumption in the previous 3 months was the treatment of injuries, while the main reason given for consuming NSAIDs during the race was pain prevention. Despite anti-inflammatory and analgesic effects, most athletes were unaware of the effects of NSAIDs, and the only adverse effects known by most athletes were the gastrointestinal complications., Conclusions: this study found a high prevalence of NSAID consumption, limited awareness of the effects and side effects of them and a high rate of nonprescribed use. It is suggested that long-distance triathlon events include in their programmes educational devices such as talks or folders about NSAID use, effects and side effects.

- Abstract
Purpose: to evaluate risk factors for the development of genital prolapse in the Brazilian population., Methods: case-control study involving 316 patients submitted to prolapse staging, according to the pelvic organ prolapse quantification system. The patients were divided into two groups: in the Case Group there were 107 patients with prolapse at stage III or IV, and in the Control Group, 209 women at stage 0 or I. In the anamnesis, the selected women have been questioned about the presence of possible risk factors for genital prolapse, such as: age, menopause age, parturition, delivery type (vaginal, caesarean section or forceps), occurrence of fetal macrosomia, family history of genital dystopia in first degree relatives, chronic cough and intestinal constipation., Results: The variables that were different between the groups were: age, body mass index, parturition, number of vaginal, caesarean section or forceps deliveries, newborn weight and positive family history for prolapse. Race, menopause age, chronic cough and intestinal constipation did not present differences between the groups. After logistic regression, only three variables have been shown to be independent risk factors: presence of at least one vaginal delivery, fetal macrosomia and positive family history for dystopia. Cesarean section was shown to be a protective factor., Conclusion: in the Brazilian population, the independent risk factor for genital prolapse were: personal antecedent of at least one vaginal delivery, fetal macrosomia and family history of dystopia.

- Abstract
Introduction: The physical activity and adequate food plays a key role in improving health and the control of diseases., Objective: This paper aims at determining the nutritional state through anthropometric measures, socioeconomic level, the most common illnesses and type of physical activity, beyond food consumption and the place where meals are taken, of under-graduate students of the Nutrition course in UFPE., Methods: The sample is constituted of 68 female students, of different periods and at ages between 18 and 27 years old. The process of selection of the sample was for convenience. The students voluntarily participated and answered three questionnaires, respectively, on their socioeconomic level (income of the family) and possible illnesses they had, measures of the cutaneous folds and type of practiced physical activity; register of consumed foods and local where the meals were carried. Statistical analysis was performed by absolute frequency, percentage, average and standard deviation. The margin of error used in the testing employees was 5%., Results: In relation to the incomes, they had predominated above three minimum wages (86%), the parents have a predominant role in the expenditure of their study (46%), followed by the father (24%), mother (9%), husband (4%), other responsible ones (10%); 7% did not give information. The most common illnesses were: allergic rhinitis, tonsillitis, sleeplessness and intestinal constipation. The weight, the height, the index of body mass and the relation waist hip of the students were within normal standards. The abdominal circumference varied only in 2.57 cm between the studied age range. In relation to the practice of physical activities, 67% were sedentary, 20% practiced light activity and 13% moderate. In relation to where the meals are had, breakfast, in its majority (76%), was carried at home, followed by supper (56%), while lunch (41%) and snack 1 (34%), at University. Among the pupils who did not inform the place where they had their meals there was a high percentage for the big meals and a small one for the minor ones. The main kinds of consumed meals were breakfast, lunch and supper (98%). For the small meals, the values were: snack 1 (54%), snack 2 (61%), snack 3 (45%). The analysis of food consumption for three days disclosed ingestion of energy with deficit of 21% in relation to the recommended one (p < 0.001); the macro-nutrients showed percentages within the standards; the intake of fiber (11.8 g/day) was less than recommended (p < 0.001). Meat, eggs and cereals were ingested daily (for about 80%); vegetables (40%), legumes, fruits and candies (25% 30%), around four or six days a week. Roots and tubercles, salty, embedded and non alcoholic drinks were consumed from one to three days weekly (70%). Animal guts were not consumed by 50% of the studied population., Conclusions: Having analyzed all this, the studied students need to modify their food habits, acquiring knowledge on the importance of a balanced diet, as well as the practice of physical activity systematically, to prevent illnesses and attain a better quality of life.

- Abstract
The two-dimensional barotropic, hydrodynamic and transport model MOHID is applied to the Patos Lagoon system using a nested modelling approach to reproduce both the lagoon and estuary hydrodynamics. A new Lagrangian oil spill model is presented and used to simulate a hypothetical oil spill in the estuary. Hydrodynamic fields are validated and used to force the oil model. Results show that the hydrodynamics of this system is mainly controlled by the wind and freshwater discharge. The dispersion, concentration and thickness evolution of the oil in the first day after the spill is determined by the equilibrium between these two factors. The freshwater discharge is the major factor controlling the oil dispersion for discharges greater than 5000 m3 while the wind assumes control for lower discharge amounts. The results presented are a first step toward a coastal management tool for the Patos Lagoon.

- Abstract
The Restinga de Jurubatiba has at least 10 plant formations, including open Clusia shrubland. This formation is composed of dense shrubs of many shapes and sizes, where Clusia hilariana is one of the most important plant species. Shrublands with Clusia (CC) are poorer in plant species and less dense than shrublands without Clusia (SC). Oryzomys subflavus (Rodentia) is the most abundant small mammal species in the open Clusia shrubland. We tested the hypothesis that the abundance of rodents would increase with the size of the patch and would be higher in SC shrublands. Rodents were captured, marked and released in three 780-m-long transects. At each capture site, we evaluated the shape of the shrubland patch, calculated the area and noted the category of the shrubland. Using ANCOVA, we ascertained whether the abundance of Oryzomys subflavus increased with the sampled area and used CC and SC shrublands differently. We also verified if the size of patches used by rodents varies in the same frequency as the size of available shrublands. Rodent abundance was found to increase significantly with the area. There were no differences in the size of the patches used by rodents and the frequency of the size of available patches. This finding indicates that O. subflavus, in the study area, is a generalist species that uses its habitat according to availability.

- Abstract
An intensive survey of ectoparasitic arthropods associated with small mammals in upland forests near Manaus, Brazil, provides information on the taxonomy and host distribution of laelapine mites in the Amazonian Region. We identified 5 genera and 21 species of these mites by comparison with representative museum specimens, the taxonomic literature, and, when possible, the original type specimens. These mites are host specific, with associations ranging from strict monoxeny (18 species) to oligoxeny (1 species) and pleioxeny (2 species). Marsupials were infested with species of Androlaelaps, echimyid rodents with Tur, and sigmodontine rodents with Gigantolaelaps, Laelaps, and Mysolaelaps. Androlaelaps bergalloi, a new species of Laelapinae, is described from the pelage of the marsupial Monodelphis brevicaudata.

- Abstract
Brazilian off-season maize production is characterized by low yield due to several factors, such as climate variability and inadequate management practices, specifically weed management. Thus, the goal of this study was to determinate the critical period of weed competition in off-season maize (Zea mays L.) crop using thermal units or growing degree days (GDD) approach to characterize crop growth and development. The study was carried out in experimental area of the University of São Paulo, Brazil, with weed control (C), as well as seven coexistence periods, 2, 4, 6, 8, and 12 leaves, flowering, and all crop cycle; fourteen treatments were done. Climate data were obtained from a weather station located close to the experimental area. To determine the critical period for weed control (CPWC) logistic models were fitted to yield data obtained in both W and C, as a function of GDD. For an arbitrary maximum yield loss fixed in 2.5%, the CPWC was found between 301 and 484 GDD (7-8 leaves). Also, when the arbitrary loss yield was fixed in 5 and 10%, the period before interference (PBI) was higher than the critical weed-free period (CWFP), suggesting that the weeds control can be done with only one application, between 144 and 410 GDD and 131 and 444 GDD (3-8 leaves), respectively. The GDD approach to characterize crop growth and development was successfully used to determine the critical period of weeds control in maize sown off-season. Further works will be necessary to better characterize the interaction and complexity of maize sown off-season with weeds. However, these results are encouraging because the possibility of the results to be extrapolated and because the potential of the method on providing important results to researchers, specifically crop modelers.

- Abstract
This study aims to describe and identify factors associated with environmental quality and characteristics of children exposed to environmental risk factors in Pelotas, Rio Grande do Sul, Brazil. This was a prospective, population-based study, including 630 children from the 1993 birth cohort. During the year 1998, environmental quality and other information were assessed using the Home Observation for the Measurement of the Environment. Data were submitted to univariate analysis. The association between the variables and the outcome was evaluated through prevalence ratios, 95% confidence intervals, and chi-square. Logistic regression was performed according to a hierarchical model. Some 97 children (15%) were living in negative environments. Eight risk factors were associated with environmental quality: low monthly family income, low maternal schooling, male gender, households with more than 7 members, 4 or more siblings, tobacco use during gestation, children sleeping in their parents' bed at age 4 years, and mothers with psychiatric disorders.

- Abstract
Objective: The objectives of the present study were to determine the prevalence of potentially pathogenic microorganisms that indicate the hygienic and sanitary conditions of human milk samples collected at a Human Milk Bank., Methods: Three hundred and thirty eight (338) samples of human milk collected from a milk bank in a maternity in the municipality of Goiânia, in the state of Goias, Brazil were submitted to microbiological analysis. The latter were plated on McConkey agar according to the type of bacteria. Among the total number of samples collected, 194 consisted of raw milk and the remaining 144 were pasteurized milk., Results: The presence of Staphylococcus spp., Streptococcus spp., yeasts and molds, and Enterobacteriaceae was verified in the raw milk samples. Staphylococcus aureus were isolated in 10 (5.2%) samples, Staphylococcus epidermidis in 28 (14.4%) samples, Streptococcus spp. in three (1.6%) samples, yeasts and molds in 43 (22.2%) and Enterobacteriaceae in 49 (25.3%) samples. In a hundred and forty four (144) samples which underwent thermal treatment Staphylococcus aureus was detected in five (3.5%) samples, Staphylococcus epidermidis in 15 (10.4%), Staphylococcus lugdenensis in two (1.4%), Streptococcus spp. in four (2.8%), yeasts and molds in 37 (25.7%), and Enterobacteriaceae in nine (6.3%)., Conclusions: Analysis indicated a high degree of contamination in raw human milk, and as for the pasteurized milk, despite elimination of the great majority of potentially pathogenic microorganisms, the percentage of yeasts and molds was higher than in raw milk, demonstrating that a lower degree of initial contamination would be necessary for pasteurization to be an efficient means of microbiological control.

- Abstract
Mesostigmatic mites of the Laelapinae Berlese, 1892 (Acari: Laelapidae) are nidicolous arthropods that commonly occur in the fur of Neotropical small mammmals. In this 2-yr study, the laelapine acarofauna associated with the small mammal community in an area of Atlantic forest on Ilha Grande, Rio de Janeiro State, was examined, including observations on patterns of host specificity, mite dispersal, ecology, and food habits. A total of 1,347 laelapines was sampled from the pelage of 6 species of small mammals (Marmosops incanus, Nectomys squamipes, Oryzomys russatus, Rhipidomys n. sp., Oxymycterus dasytrichus, and Trinomys dimidiatus), all of which occurred exclusively in monoxenous associations with their hosts. No evidence of a blood meal was observed in the gut of the mites. With the exception of the 2 species of Tur, mite populations on hosts were entirely or nearly restricted to adult females. These results, together with some morphological characteristics of laelapines, reinforce the hypotheses that Neotropical laelapine mites are not ectoparasitic, and that females disperse by phoresy.
