ABSTRACT

The objective of this study is to describe the nutritional status of adult and elderly patients with American Tegumentary Leishmaniasis (ATL). It was conducted a longitudinal study in 68 adult and elderly patients with ATL treating at the Surveillance Leishmaniasis Laboratory at the Evandro Chagas Clinical Research Institute, Oswaldo Cruz Foundation (Fiocruz), from 2009 to 2012. The nutritional assessment included the body mass index (BMI) and serum albumin levels. The clinical evolution (epithelialization and wound healing) was measured up to two years after ATL treatment. Most of the sample was composed of men (71%), adults (73%), with household income of 1-5 minimum wages (79%), and incomplete elementary school (48.5%). The predominant ATL form was cutaneous (72%), and 39% presented comorbidities, the most frequent was hypertension (30.8%). The most prevalent clinical and nutritional events were: recent decrease in food intake (23.9%); nasal obstruction (22.1%); oral ulcer (14.7%), anorexia and dysphagia (13.2% each) and odynophagia (10.3%). The total healing time was 115.00 (IR=80-230) days for skin lesions, and 120.00 (IR=104.50-223.50) days for mucous membrane lesions. Low body weight in 10%, and hypoalbuminemia in 12% of the patients have been observed. Low body weight was associated with age, mucosal leishmaniasis (ML), nasal obstruction, recent decrease in food intake and hypoalbuminemia. As for serum albumin depletion, association with the ML, dyspnea, dysphagia, odynophagia, recent decrease in food intake, absence of complete healing of the skin lesions, and increased healing time for mucous membrane lesions, was observed. The ML and their events that affect the alimentary intake have been related to the impairment of the nutritional status. Additionally, serum albumin depletion negatively affected the healing of the lesions, suggesting that a nutritional intervention can increase the effectiveness of the ATL treatment.

ABSTRACT

We report 16 new laser lines generated in a short-wavelength far-infrared Fabry-Perot laser cavity. The CO(2) pump laser is coupled into the far-infrared laser outside the far-infrared laser mode, and the cavity uses a 45 degrees adjustable output coupling mirror; this combination results in a low-loss Fabry-Perot cavity for wavelengths below 150 microm. The new lines are of medium and strong intensity and have wavelengths in the region 26.2-125.7 microm.
