Abstract. India is one of three countries that account for an estimated 300,000 of 500,000 cases of visceral leishmaniasis (VL) occurring annually. Bihar State is the most affected area of India, with more than 90% of the cases. Surveys were conducted in two villages within the Saran district of Bihar, India, from 2009 to July of 2011 to assess risk factors associated with VL. Forty-five cases were identified, and individuals were given an oral survey. The results indicated that men contracted the disease more than women (58%), and cases over the age of 21 years accounted for 42% of the total VL cases. April to June showed the highest number of new cases. Of 135 households surveyed for sleeping conditions, 95% reported sleeping outside, and 98% slept in beds. Proximity to VL cases was the greatest risk factor (cluster 1 relative risk = 11.89 and cluster 2 relative risk = 138.34). The VL case clustering observed in this study can be incorporated in disease prevention strategies to more efficiently and effectively target VL control efforts.

Visceral leishmaniasis (VL), known as Kala-azar in India, is a parasite transmitted by the bite of the sand fly vector Phlebotomus argentipes. Published information on the species indicates it is a poor flyer, mainly hopping and gliding. This study describes the vector as more arboreal than previously documented. Data collected indicate the ability of P. argentipes and Sergentomyia spp to attain vertical heights in Palmyra palm trees Borassus flabellifer up to 18.4 m above ground level. To determine if sand flies were either climbing the tree trunk to rest in the canopy or flying, sticky traps were set around the tree trunk and checked for captures overnight. CDC traps set in the palm tree canopy resulted in the capture of 5,067 sand flies, 3,990 of which were P. argentipes. Traps were set during daylight hours to determine if sand flies remained and rested in the canopy. A total of 128 sand flies were trapped over 29 trap days in the palm trees. With the CDC traps, 130 P. argentipes and no Sergentomyia spp were captured. The converse was true for the sticky traps set around tree trunks 3 m below the CDC traps. Of the 105 sand flies collected, only one was P. argentipes and 104 were Sergentomyia spp. As reported elsewhere, this indicates Sergentomyia spp tend to climb and hop, wheareas P. argentipes are capable of longer and more sustained flight. Data presented herein suggest that P. argentipes is more exophylic and exophagic than previously reported. These findings have implications for sand fly control.

Objectives (1) Assess effects of a modified Family Integrated Care (FICare) model on U.S. Neonatal Intensive Care Unit (NICU) parents; (2) Evaluate NICU nurses’ perspectives. Design Case -control design with parental stress assessed before and after NICU-wide FICare implementation using Parent Stressor Scale: NICU (PSS:NICU) questionnaire. In addition, stratification by degree of participation evaluated associations with parental stress, parental-staff communication and discharge readiness. Questionnaires captured nursing perspectives on FICare. Results 79 parents (88%) participated prior to FICare; 90 (90%) after. Parent stress was lower ( p < 0.001) with FICare. Parents learning 5–15 infant-care skills had lower stress compared to those learning <5 ( p = 0.008). Parent utilization of an educational app was associated with improved communication frequency ( p = 0.007) and quality ( p = 0.012). Bedside NICU nurses reported multiple positive associations of FICare for parents and staff. Conclusions Any degree of FICare participation decreases parental stress; increased participation has multiple positive associations.
