Pediatric Tetanus in Central Pennsylvania.

Approximately 20% of the nationally reported tetanus infections in children aged 0 to 14 years that occurred in the United States between 2005 and 2015 were treated at Penn State Children's Hospital. With an electronic medical record search, we identified 5 cases of pediatric tetanus; 100% of these cases occurred in unimmunized children. Their median length of stay was 10 days, and the costs were significant.

Health knowledge and health practices in Makeni, Sierra Leone: a community-based household survey.

BACKGROUND: We characterize health knowledge and practices in urban and rural Makeni, Sierra Leone, drawing comparisons between areas served by community health workers (CHWs) with those that are not. We also inquire about causes of infant and maternal mortality and how they are understood in the local context. Our objective was to provide a baseline understanding of health knowledge and practices in Makeni during the implementation of a CHW program. METHODS: We conducted 100 household interviews in Makeni City and rural villages in the surrounding area. We compared data between urban and rural areas to identify differences in health knowledge and practices. RESULTS: Our sample size covered 855 individuals. Insecticide treated bednet ownership was lower in urban settings compared to rural populations (58% vs 94%; p<.001). With regards to maternal mortality, most respondents indicated 'no clinic' (lack of clinical care or skipped antenatal care visits) as the primary cause (n=35), followed by bleeding (n=17), 'lack of blood' (anemia) (n=11) and 'will of God' (n=11). CONCLUSIONS: This initial survey of health knowledge and practices in rural and urban Makeni, Sierra Leone, highlights some simple opportunities for community health promotion, health education programming and behavioral interventions. Findings will inform future iterations of a CHW training module for community health education.

Does a significant reduction in malaria risk make lopinavir/ritonavir-based ART cost-effective for children with HIV in co-endemic, low-resource settings?

BACKGROUND: HIV infection and malaria co-infection is not uncommon among children in co-endemic regions, and evidence suggests that HIV is a risk factor for severe malaria among children. HIV protease inhibitors (PIs) are highly effective in pediatric HIV treatment regimens, however, their effectiveness against malaria has been mixed, with some PIs demonstrating in vitro activity against Plasmodium falciparum. Recent findings suggest lopinavir/ritonavir (LPV/r)-based treatment regimens reduce the incidence of malaria infection by over 40% in pediatric HIV patients compared to non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens. METHODS: We assessed whether a significant reduction in malaria risk makes LPV/r-based ART regimens cost-effective compared to NNRTI-based regimens in co-endemic, low-resource settings. We modeled the difference in unit cost per disability adjusted life year (DALY) gained among two theoretical groups of HIV+ children under 5 years old receiving ART in a resource-limited setting co-endemic for malaria. The first group received standard NNRTI-based antiretrovirals, the second group received a standard regimen containing LPV/r. We used recent cohort data for the incidence reduction for malaria. Drug costs were taken from the 2011 Clinton Health Access Initiative Antiretroviral (ARV) ceiling price list. DALYs for HIV and malaria were derived from WHO estimates. RESULTS: Our model suggests a unit cost of US$147 per DALY gained for the LPV/r-based group compared to US$37 per DALY gained for the NNRTI-based group. CONCLUSION: In HIV and malaria co-endemic settings, considerations of PI cost effectiveness incorporating known reductions in malaria mortality suggest a nominal increase in DALYs gained for PIs over NNRTI-based regimens for HIV positive children under five on ART. Our analysis was based on several assumptions due to lack of sound data on malaria and HIV DALY attribution among pediatric populations. Further study in this area is required.
