Sand Fly Fauna (Diptera, Pcychodidae, Phlebotominae) in Different Leishmaniasis-Endemic Areas of Ecuador, Surveyed Using a Newly Named Mini-Shannon Trap

To study the sand fly fauna, surveys were performed at four different leishmaniasis-endemic sites in Ecuador from February 2013 to April 2014. A modified and simplified version of the conventional Shannon trap was named “mini-Shannon trap” and put to multiple uses at the different study sites in limited, forested and narrow spaces. The mini-Shannon, CDC light trap and protected human landing method were employed for sand fly collection. The species identification of sand flies was performed mainly based on the morphology of spermathecae and cibarium, after dissection of fresh samples. In this study, therefore, only female samples were used for analysis. A total of 1,480 female sand flies belonging to 25 <i>Lutzomyia</i> species were collected. The number of female sand flies collected was 417 (28.2%) using the mini-Shannon trap, 259 (17.5%) using the CDC light trap and 804 (54.3%) by human landing. The total number of sand flies per trap collected by the different methods was markedly affected by the study site, probably because of the various composition of species at each locality. Furthermore, as an additional study, the attraction of sand flies to mini-Shannon traps powered with LED white-light and LED black-light was investigated preliminarily, together with the CDC light trap and human landing. As a result, a total of 426 sand flies of nine <i>Lutzomyia</i> species, including seven man-biting and two non-biting species, were collected during three capture trials in May and June 2014 in an area endemic for leishmaniasis (La Ventura). The black-light proved relatively superior to the white-light with regard to capture numbers, but no significant statistical difference was observed between the two traps.

Indicadores de sintomas depresivos en una muestra de jóvenes de 12 a 17 años de edad con diabetes mellitus tipo I / Indicators of depression symptoms in a sample of 12 to 17 year-old youths with diabetes mellitus type I

The purpose of this study was to find out what percent of a group of patients 12 to 17 years old and with a diagnosis of Diabetes Mellitus type I have depressive symptomatology. We also wanted to know if there were gender differences in regard to depressive symtomatology in this group. We used a revised and adapted spanish translation of the Beck Depression Inventory, the IDB-R. It was administered to a group of 49 patients ages 12 to 17 with Diabetes Mellitus type I. The mean score of the group at the IDR-R was 9.33, which according to the instrument represents absence of depressive symptomatology. We found that 36.7of this group obtained a score greater than 10 in the IDB-R which according to this instrument, it means that depressive symptomatology was present. The symptoms most reported by the females were difficulties taking decisions and sleep problems. The symptom most reported by the males was change in appetite.
