Mental illness in adults with HIV and HCV infection: Indian Health Service, 2001-2020
Smith CM , Kennedy JL , Evans ME , Person MK , Haverkate R , Apostolou A . Am J Prev Med 2022 63 (3) e77-e86 INTRODUCTION: Mental health disorders (MHDs) and substance use disorders (SUDs) in people living with HIV, hepatitis C virus (HCV) infection, and HIV/HCV coinfection are common and result in significant morbidity. However, there are no national prevalence estimates of these comorbidities in American Indian and Alaska Native (AI/AN) adults with HIV, HCV infection, or HIV/HCV coinfection. This study estimates the prevalence of MHD and SUD diagnoses in AI/AN adults diagnosed with HIV, HCV infection, or HIV/HCV coinfection within the Indian Health Service (IHS). METHODS: In 2021, a cross-sectional study using data from the National Patient Information Reporting System was completed to identify MHD or SUD diagnoses in AI/AN adults with HIV, HCV infection, or HIV/HCV coinfection within the IHS during fiscal years 2001‒2020. Logistic regression was used to compare the odds of MHD or SUD diagnoses, adjusting for age and sex. RESULTS: Of AI/AN adults diagnosed with HIV, hepatitis C virus infection, or HIV/HCV coinfection, the period prevalence of MHD or SUD diagnoses ranged from 57.2% to 81.1%. Adjusting for age and sex, individuals with HCV infection had higher odds of receiving a MHD diagnosis (AOR=1.57; 95% CI=1.47, 1.68) or SUD diagnosis (AOR=3.40; 95% CI=3.18, 3.65) than those with HIV, and individuals with HIV/HCV coinfection had higher odds of receiving a MHD diagnosis (AOR=1.60; 95% CI=1.35, 1.89) or SUD diagnosis (AOR=2.81; 95% CI=2.32, 3.41) than those with HIV. CONCLUSIONS: MHD and SUD diagnoses were common in AI/AN adults diagnosed with HIV, HCV infection, or HIV/HCV coinfection, highlighting the need for culturally appropriate screening and treatment programs sensitive to the diverse strengths of AI/AN populations and structural challenges they endure. |
Dead-end hollow-fiber ultrafiltration for recovery of diverse microbes from water
Smith CM , Hill VR . Appl Environ Microbiol 2009 75 (16) 5284-9 Dead-end ultrafiltration (DEUF) is an alternative approach to tangential-flow hollow-fiber ultrafiltration that can be readily employed under field conditions to recover microbes from water. The hydraulics of DEUF and microbe recovery for a new DEUF method were investigated using 100-liter tap water samples. Pressure, flow rate, and temperature were investigated using four hollow-fiber ultrafilter types. Based on hydraulic performance, the Asahi Kasei REXEED 25S ultrafilter was selected for microbe recovery experiments. Microbe recovery experiments were performed using MS2 bacteriophage, Enterococcus faecalis, Clostridium perfringens spores, and Cryptosporidium parvum oocysts. Microbes were recovered from ultrafilters by backflushing using a surfactant solution. Average flow rates were 2.1 liters/min for 100-liter water samples having turbidities of 0.28 to 4.3 nephelometric turbidity units (NTU), and no evidence of appreciable filter clogging was observed. The DEUF average recovery efficiencies for each study analyte in tap water were as follows: for E. faecalis, 93% +/- 16%; for MS2, 57% +/- 7.7%; for C. perfringens spores, 94% +/- 22%; and for C. parvum, 87% +/- 18%. Average microbe recoveries for tap water amended with surface water (average turbidity = 4.3 NTU) were as follows: for E. faecalis, 78% +/- 12%; for MS2, 73% +/- 13%; for C. perfringens, 57% +/- 21%; and for C. parvum, 83% +/- 21%. These data demonstrate that DEUF is an effective method for recovering diverse microbes from water and should be a useful tool for field-based environmental investigations. |
