O trabalho avaliou a influência da termorretificação na resistência ao ataque de cupins em madeira de Qualea paraensis. A madeira utilizada no experimento foi submetida à termorretificação com duas temperaturas (180 e 200°C) e dois períodos de permanência em estufa (120 e 240 min.). Após os tratamentos térmicos, as amostras de madeira foram submetidas ao ensaio de biodegradação, sendo mantidas em ambiente controlado, com presença do cupim Nasutitermes corniger. (Dictyoptera: Termitidae), durante 45 dias. Os resultados foram submetidos a análise de variância e as médias comparadas pelo teste de Tukey a 5% de significância. Os diferentes tratamentos térmicos alteraram as características avaliadas para a madeira de Qualea paraensis. Três dos quatro tratamentos térmicos avaliados aumentaram a massa específica da madeira. Contudo, também foi verificado um aumento da suscetibilidade da madeira ao ataque de cupins de madeira úmida.

The study evaluated the influence of heat treatment on termites attack of Qualea paraensis. wood. The wood used in the experiment was submitted to heat treatment with two temperatures (180 and 200°C) and two periods of stay in the oven (120 and 240 min.). After heat treatment the wood specimens were subjected to the biodegradation test, being maintained in a controlled environment with presence of the termites Nasutitermes corniger. (Dictyoptera: Termitidae) for 45 days. The results were submitted to variance analysis and the means compared to Tukey's test at 5% significance. The thermal treatments for the Qualea paraensis made modifiction characteristics of the wood. Three of the four thermal treatments evaluated increased the density. However, there was also an increase too in susceptibility of wood to the attack of humid wood termites.

Objetivos: A terapia antirretroviral altamente ativa (HAART) tem melhorado e aumentado a vida de milhares de pessoas que vivem com a infecção pelo HIV/AIDS em todo o mundo. No entanto, este tratamento pode levar ao desenvolvimento da síndrome da lipodistrofia (LDS). Este estudo foi desenvolvido para avaliar a prevalência de auto-relato de LDS, perfil nutricional e medidas antropométricas de pacientes com HIV/AIDS. Métodos: Estudo observacional de 227 pacientes adultos, divididos em: Grupo 1: 92 pacientes em HAART e com LDS; Grupo 2: 70 pacientes em tratamento com HAART e sem LDS e Grupo 3: 65 pacientes que não tomam HAART. O estado nutricional foi avaliado pelo índice de massa corporal (IMC) e o percentual de gordura corporal (%GC) por meio de medidas antropométricas. Resultados: A prevalência de auto-relato de LDS foi de 44% entre as mulheres e 39% entre os homens. DC do tríceps (PCT) apresentou-se mais elevada no grupo HAART e LDS (homens p < 0,001; mulheres p < 0,007) em comparação com aqueles sem HAART, respectivamente. IMC revelou excesso de peso para a maioria dos indivíduos. Conclusões: As medidas antropométricas foram úteis para confirmar a prevalência de auto-relato da síndrome da lipodistrofia. A avaliação das dobras dos braços e pernas revelou-se um bom método para avaliação antropométrica de lipoatrofia de membro, independentemente do sexo. Estes resultados permitiram o estabelecimento de estratégias para o diagnóstico precoce da LDS na prática clínica, em pessoas vivendo com HIV / AIDS.

Introduction: Highly Active Antiretroviral Therapy (HAART) has improved and extended the lives of thousands of people living with HIV/AIDS around the world. However, this treatment can lead to the development of adverse reactions such as lipoatrophy/lipohypertrophy syndrome (LLS) and its associated risks. Objective: This study was designed to assess the prevalence of self-reported lipodystrophy and nutritional status by anthropometric measurements in patients with HIV/AIDS. Methods: An observational study of 227 adult patients in the Secondary Immunodeficiencies Outpatient Department of Dermatology, Hospital das Clínicas, Faculty of Medicine, University of São Paulo (3002 ADEE-HCFMUSP). The sample was divided into three groups; Group 1 = 92 patients on HAART and with self-reported lipodystrophy, Group 2 = 70 patients on HAART without self-reported lipodystrophy and Group 3 = 65 patients not taking HAART. The nutritional status of individuals in the study sample was determined by body mass index (BMI) and percentage of body fat (% BF). The cardiovascular risk and diseases associated with abdominal obesity were determined by waist/hip ratio (WHR) and waist circumference (WC). Results: The prevalence of self-reported lipoatrophy/lipohypertrophy syndrome was 33% among women and 59% among men. Anthropometry showed depletion of fat mass in the evaluation of the triceps (TSF) in the treatment groups with HAART and was statistically independent of gender; for men p = 0.001, and for women p = 0.007. Similar results were found in the measurement of skin folds of the upper and lower body (p = 0.001 and p = 0.003 respectively). In assessing the nutritional status of groups by BMI and % BF, excess weight and body fat were more prevalent among women compared to men (p = 0.726). The WHR and WC revealed risks for cardiovascular and other diseases associated with abdominal obesity for women on HAART and with self-reported LLS (p = 0.005) and (p = 0.011). Conclusions: Anthropometric measurements were useful in the confirmation of the prevalence of LLS. BMI alone does not appear to be a good parameter for assessing the nutritional status of HIV-infected patients on HAART and with LLS. Other anthropometric measurements are needed to evaluate patients with the lipoatrophy/lipohypertrophy syndrome.
