Xiaomin Zhao, Wu-Seng Lung
Hormones excreted by livestock metabolisms often enter surface water through feces and urine and can potentially cause adverse impacts to aquatic biota. This study involved a modeling analysis of 17β-estradiol (E2), a prevalent estrogen, in the South River watershed located in Augusta County, Virginia from 2013 to 2015. Cattle manure, poultry litter, biosolids, septic systems, and wastewater treatment plants (WWTPs) were considered as sources of E2 in this study. The EPA's BASINS modeling framework was configured to track the fate and transport of E2...

BACKGROUND: Bolivia has the highest prevalence of Chagas disease (CD) in the world (6.1%), with more than 607,186 people with Trypanosoma cruzi infection, most of them adults. In Bolivia CD has been declared a national priority. In 2009, the Chagas National Program (ChNP) had neither a protocol nor a clear directive for diagnosis and treatment of adults. Although programs had been implemented for congenital transmission and for acute cases, adults remained uncovered. Moreover, health professionals were not aware of treatment recommendations aimed at this population, and research on CD was limited; it was difficult to increase awareness of the disease, understand the challenges it presented, and adapt strategies to cope with it...

BACKGROUND: Reactive case detection (RACD) around passively detected malaria cases is a strategy to identify and treat hotspots of malaria transmission. This study investigated the unproven assumption on which this approach is based, that in low transmission settings, infections cluster over small scales. METHODS: A prospective case-control study was conducted between January 2013 and August 2014 in Ohangwena and Omusati regions in north central Namibia. Patients attending health facilities who tested positive by malaria rapid diagnostic test (RDT) (index cases) were traced back to their home...

PURPOSE OF REVIEW: Recent research has provided extensive characterization as to the frequency and nature of sleep disturbances following traumatic brain injury (TBI). This review summarizes the current state of knowledge and proposes future directions for research. RECENT FINDINGS: Complaints of sleep disturbance are common following TBI, and objective assessments of sleep largely corroborate these complaints. Sleep is often disturbed in the acute phase postinjury and can persist for decades, with the prevalence of sleep disorders higher in patients with TBI as compared with the general population...

While public awareness of sleep related disorders is growing, sleep apnea syndrome (SAS) remains a public health and economic challenge. Over the last two decades, extensive controlled epidemiologic research has clarified the incidence, risk factors including the obesity epidemic, and global prevalence of obstructive sleep apnea (OSA), as well as establishing a growing body of literature linking OSA with cardiovascular morbidity, mortality, metabolic dysregulation, and neurocognitive impairment. The US Institute of Medicine Committee on Sleep Medicine estimates that 50-70 million US adults have sleep or wakefulness disorders...

Neurologic complications in persons with HIV infection are less severe in the era of potent antiretroviral therapy but remain highly prevalent. Prior to the use of antiretroviral therapy, opportunistic infections of the central nervous system (CNS) and CNS malignancy were common. Progressive multifocal leukoencephalopathy (PML), however, remains a diagnostic challenge in HIV-infected individuals, and no effective antiviral treatment for PML is currently available. Primary neurologic complications of acute HIV infection include aseptic meningitis and acute inflammatory demyelinating polyneuropathy...

House structure may influence the risk of malaria by affecting mosquito entry and indoor resting. Identification of construction features associated with protective benefits could inform vector control approaches, even in low-transmission settings. We examined the association between house structure and malaria prevalence in a cross-sectional analysis of 2,788 children and adults residing in 866 houses in a low-transmission area of Southern Province, Zambia, over the period 2008-2012. Houses were categorized according to wall (brick/cement block or mud/grass) and roof (metal or grass) material...

In stable transmission areas, malaria is the leading cause of anemia in children. Anemia in children is proposed as an added sensitive indicator for community changes in malaria prevalence. We report short-term temporal variations of malaria and anemia prevalence in rural Malawian children. Data from five repeated cross-sectional surveys conducted over 1 year in rural communities in Chikwawa District, Malawi, were analyzed. Different households were sampled per survey; all children, 6-59 months, in sampled household were tested for malaria parasitemia and hemoglobin levels using malaria rapid diagnostic tests (mRDT) and Hemocue 301, respectively...

Approximately one-quarter of the world's population is infected with at least one species of soil-transmitted helminth (STH). The role of produce and hands in STH transmission is not well understood. We collected and processed mother hand rinse and garden-grown produce rinse samples from 116 rural households in Kakamega, Kenya, in an area previously identified to have high STH egg contamination in household soil. Ascaris was the only STH species detected; 0.9% of hand rinse, 3.5% of leafy produce, and 1.8% of root produce samples had Ascaris eggs...

Throughout many developing and tropical countries around the world, malaria remains a significant threat to human health. One barrier to malaria elimination is the ability to safely administer primaquine chemotherapy for the radical cure of malaria infections in populations with a high prevalence of glucose-6-phosphate dehydrogenase (G6PD) deficiency. In the current study, a field trial of the world's first quantitative, point-of-care assay for measuring G6PD activity was conducted in Haiti. The performance of the CareStart Biosensor Analyzer was compared with the gold standard spectrophotometric assay and genotyping of the G6PD allele in schoolchildren (N = 343) from the Ouest Department of Haiti...
