  • Trends in the incidence of possible severe bacterial infection and case fatality rates in rural communities in Sub-Saharan Africa, South Asia and Latin America, 2010-2013: a multicenter prospective cohort study. Reproductive health Hibberd, P. L., Hansen, N. I., Wang, M. E., Goudar, S. S., Pasha, O., Esamai, F., Chomba, E., Garces, A., Althabe, F., Derman, R. J., Goldenberg, R. L., Liechty, E. A., Carlo, W.

    Possible severe bacterial infections (pSBI) continue to be a leading cause of global neonatal mortality annually. With the recent publications of simplified antibiotic regimens for treatment of pSBI where referral is not possible, it is important to know how and where to target these regimens, but data on the incidence and outcomes of pSBI are limited.We used data prospectively collected at 7 rural community-based sites in 6 low and middle income countries participating in the NICHD Global Network's Maternal and Newborn Health Registry, between January 1, 2010 and December 31, 2013. Participants included pregnant women and their live born neonates followed for 6 weeks after delivery and assessed for maternal and infant outcomes.In a cohort of 248,539 infants born alive between 2010 and 2013, 32,088 (13 %) neonates met symptomatic criteria for pSBI. The incidence of pSBI during the first 6 weeks of life varied 10 fold from 3 % (Zambia) to 36 % (Pakistan), and overall case fatality rates varied 8 fold from 5 % (Kenya) to 42 % (Zambia). Significant variations in incidence of pSBI during the study period, with proportions decreasing in 3 sites (Argentina, Kenya and Nagpur, India), remaining stable in 3 sites (Zambia, Guatemala, Belgaum, India) and increasing in 1 site (Pakistan), cannot be explained solely by changing rates of facility deliveries. Case fatality rates did not vary over time.In a prospective population based registry with trained data collectors, there were wide variations in the incidence and case fatality of pSBI in rural communities and in trends over time. Regardless of these variations, the burden of pSBI is still high and strategies to implement timely diagnosis and treatment are still urgently needed to reduce neonatal mortality.The study was registered at ( NCT01073475 ).

  • Immune Reconstitution Inflammatory Syndrome in Human Immunodeficiency Virus-Infected Children in Peru PEDIATRIC INFECTIOUS DISEASE JOURNAL Wang, M. E., Castillo, M. E., Montano, S. M., Zunt, J. R. 2009; 28 (10): 900-903


    Immune reconstitution inflammatory syndrome (IRIS) after initiating highly active antiretroviral therapy (HAART) has not been widely studied in children, especially in resource-poor settings.Retrospective cohort study of HIV-infected children initiating HAART between 2001 and 2006 at a tertiary pediatric hospital in Lima, Peru. Charts were reviewed for 1 year after HAART initiation. IRIS was defined as a HAART-associated adverse event caused by an infectious or inflammatory condition in patients with documented virologic or immunologic success.Ninety-one children (52% female) received HAART for at least 1 year. Median age at initiation was 5.7 years; 91% were ART naive and 73% had CDC stage C disease. The incidence of IRIS was 19.8 events per 100 person years (95% CI: 11.5-28.0). Median time to IRIS was 6.6 weeks after HAART initiation (range: 2-32 weeks). There were 18 IRIS events, 11 unmasking and 7 paradoxical. These included associations with Mycobacterium tuberculosis in 4 cases, Bacillus Calmette Guerin lymphadenitis in 1 case, varicella zoster virus in 6 cases and herpes simplex labialis in 6 cases. Children who developed IRIS had a higher baseline HIV viral load (P = 0.02) and an indicator of malnutrition (P = 0.007) before HAART initiation.IRIS occurred in 20% of HIV-infected children starting HAART in Peru and was associated with more advanced disease and malnutrition. Future research is needed to examine specific risk factors associated with pediatric IRIS to allow prompt identification and treatment of IRIS.

  • Changes in health insurance coverage during the economic downturn: 2000-2002. Health affairs Holahan, J., Wang, M. 2004: W4-31 42


    Using Current Population Survey data from 2000-2002, this paper documents the changes that led the uninsured population to grow by 3.8 million during that time period. All of the increase in the uninsured occurred among adults, and two-thirds was among low-income adults. The extent to which the loss of employer coverage resulted in people becoming uninsured depended on their access to public programs: Children were more likely than adults to gain public coverage; women more likely than men; and parents more likely than nonparents. Middle- and higher-income Americans were also affected because many lost income and because rates of employer coverage were lower.
