Single-Center Long-Term Follow-Up of Kidney Donors in Argentina (Hospital Italiano de Buenos Aires).

INTRODUCTION: Living kidney donor (LKD) transplantation is increasing due to organ shortage. Clinical studies have shown that the risk of developing end-stage renal disease (ESRD) in donors is similar to that in the general population. Our goal was to evaluate postdonation renal outcomes assessed by glomerular filtration rate (GFR), proteinuria, and blood pressure. METHODS: A total of 210 LKD transplants were performed at Hospital Italiano de Buenos Aires between 2000 and 2014. Postdonation outcomes were analyzed in 109 donors. GFR was assessed by 24-hour creatinine clearance (as 24-hour ClCr) and estimated using the Modification of Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations. Additionally, we correlated the predonation renal functional reserve (RFR) with postdonation GFR. Donor results were compared to the expected GFR (adjusted to age and single kidney). Other renal outcome indicators measured were albuminuria and blood pressure, and they were compared (predonation and postdonation) using univariate analysis. RESULTS: A total of 109 patients were followed up for 47 ± 34 months (range, 12-168): 70% were female, age at donation was 48.58 years (range, 25-70), and predonation serum creatinine was 0.85 ± 0.17 mg/dL. Postnephrectomy GFR (24-hour ClCr) was significantly lower compared to predonation GFR (105.38 ± 21.78 mL/min/1.73 m2 vs 90.14 ± 17.78 mL/min/1.73 m2). However, postdonation GFR was not significantly different compared to the expected GFR. No differences were found for blood pressure or albuminuria. Age >50 and an RFR (<20%) was associated with a lower GFR. CONCLUSIONS: In this population of LKD, renal outcome (24-hour CrCl, albuminuria, and blood pressure) was within the expected outcome for healthy individuals after uninephrectomy.

Insect repellent jacket tests against biting midges (diptera: Culicoides) in Panama.

Light-weight net jackets treated with N,N-diethyl-m-toluamide (deet) were field-tested in Panama against five species of biting midges, principally Culicoides furens (Poey) and C. barbosai Wirth and Blanton. The deet-treated jacket provided 87-93% protection. Time of day as well as season appeared to influence the proportionate numbers of species collected. The mean coefficient of protection was slightly lower during morning tests when C. barbosai was most abundant and higher during evening tests when C. furens was most abundant.

Evaluation of personal protection methods against phlebotomine sand flies including vectors of leishmaniasis in Panama.

Three personal protection methods were evaluated against phlebotomine sand flies in Panama. Skin applications of five selected repellents including deet (N,N-diethyl-m-toluamide) provided a mean coefficient of protection (CP) of 99.2% against the attack of at least three sand fly species. Deet-treated net jackets also provided good protection, but it was concluded that an additional application of repellent to the unprotected face was necessary for maximum protection. Permethrin-treated clothing did not provide the protection expected. Apparently sand fly behavior and resistance to quick knock-down were responsible for the numbers of bites recorded, and therefore maximum protection from bites would require application of deet or another suitable repellent to the exposed skin when wearing permethrin-treated clothing.
