Natural And Technologic Hazardous Material Releases During And After Natural Disasters: A Review, Stacy Young, Lina Balluz, Josephine Malilay

United States Public Health Resources

Natural disasters may be powerful and prominent mechanisms of direct and indirect hazardous material (hazmat) releases. Hazardous materials that are released as the result of a technologic malfunction precipitated by a natural event are referred to as natural-technologic or na-tech events. Na-tech events pose unique environmental and human hazards. Disaster-associated hazardous material releases are of concern, given increases in population density and accelerating industrial development in areas subject to natural disasters. These trends increase the probability of catastrophic future disasters and the potential for mass human exposure to hazardous materials released during disasters. This systematic review summarizes direct and indirect …

Real-Time Fluorescence Pcr Assays For Detection And Characterization Of Heat-Labile I And Heat-Stable I Enterotoxin Genes From Enterotoxigenic Escherichia Coli, Udo Reischl, Mohammad T. Youssef, Hans Wolf, Eija Hyytia-Trees, Nancy A. Strockbine

United States Public Health Resources

To facilitate the diagnosis of enterotoxigenic Escherichia coli (ETEC) infections in humans, we developed and evaluated real-time fluorescence PCR assays for the Roche LightCycler (LC) against the enterotoxin genes commonly present in strains associated with human illness. Separate LC-PCR assays with identical cycling conditions were designed for the type I heat-labile enterotoxin (LT I) and the type I heat-stable enterotoxin (ST I) genes, using the LC hybridization probe format. A duplex assay for ST I with two sets of amplification primers and three hybridization probes was required to detect the major nucleotide sequence variants of ST I, ST Ia and …

Unconditional logistic regression was used to calculate adjusted odds ratios (ORs) for farming and for use of individual and chemical classes of insecticides and herbicides, including pesticides classified as nitrosatable (able to form N-nitroso compounds on …

Neurobehavioral Evaluation For A Community With Chronic Exposure To Hydrogen Sulfide Gas, Steven G. Inserra, Betty L. Phifer, W. Kent Anger, Michael Lewin, Roberta Hilsdon, Mary C. White

United States Public Health Resources

In May 2000, the Agency for Toxic Substances and Disease Registry of the US government conducted a health investigation in response to community concerns regarding ambient and indoor hydrogen sulfide (H₂S), odor, and health symptoms in Dakota City, Nebraska. The objective was to determine whether adult residents in an area with repeated exposure to H₂S showed poorer performance on neurobehavioral tests than unexposed residents. Study participants were required to meet age (≥16 years of age) and length of residency (2 years) eligibility requirements. A battery of computer-assisted standardized neurobehavioral tests was administered in English or Spanish. …

Outbreak Of Pruritic Rashes Associated With Mites — Kansas, 2004

United States Public Health Resources

In late August 2004, the Kansas Department of Health and Environment (KDHE) received reports from the Crawford County Health Department (CCHD) of approximately 300 residents of Pittsburg, Kansas (2000 population: 19,243), seeking care for a pruritic rash of unknown etiology. In early September, three neighboring counties in Kansas and two neighboring states (Missouri and Nebraska) also reported such cases. These events prompted KDHE to request assistance from CDC. Additional cases subsequently were reported in Oklahoma and Texas. This report describes the investigation in Crawford County, Kansas, by public health agencies and entomologists to identify the etiology of the pruritic rash …

Alcohol And Hiv Decrease Proteasome And Immunoproteasome Function In Macrophages: Implications For Impaired Immune Function During Disease, James Haorah, David Heilman, Casey Diekmann, Natalia Osna, Terrence M. Donohue Jr., Anuja Ghorpade, Yuri Persidsky

United States Public Health Resources

Proteasomes (proteinase complexes, PR) and immunoproteasomes (IPR) degrade damaged proteins and affect protein processing required for antigen presentation by mononuclear phagocytes. These critical immune processes are attenuated during progressive HIV-1 infection and are affected by alcohol abuse. To investigate the mechanisms underlying these functional changes, we measured PR and CYP2E1 activities [an ethanol (EtOH) metabolizing enzyme] and reactive oxygen species (ROS) in human monocyte-derived macrophages (MDM) following HIV-1 infection and EtOH treatment. We observed progressive declines of PR activity and PR/IPR contents in HIV-1-infected MDM. PR activity and IPR expression increased after IFN-γ stimulation but reduced after HIV-1 infection. EtOH …

Molecular Characterization Of Noroviruses Detected In Diarrheic Stools Of Michigan And Wisconsin Dairy Calves: Circulation Of Two Distinct Subgroups, Annabel G. Wise, Stephan S. Monroe, Lora E. Hanson, Daniel L. Grooms, Donald Sockett, Roger K. Maes

United States Public Health Resources

Noroviruses have emerged as the leading worldwide cause of acute non-bacterial gastroenteritis in humans. The presence of noroviruses in diarrheic stool samples from calves on Michigan and Wisconsin dairy farms was investigated by RT-PCR. Norovirus-positive samples were found on all eight farms studied in Michigan and on 2 out of 14 farms in Wisconsin. Phylogenetic analyses of partial polymerase and capsid sequences, derived for a subset of these bovine noroviruses, showed that these strains formed a group which is genetically distinct from the human noroviruses, but more closely related to genogroup I than to genogroup II human noroviruses. Examination of …

Transcriptional Regulation Of The Murine Elf3 Gene In Embryonal Carcinoma Cells And Their Differentiated Counterparts: Requirement For A Novel Upstream Regulatory Region, Jingwen Hou, Phillip J. Wilder, Cory T. Bernadt, Brian Boer, Richard M. Neve, Angie Rizzino

United States Public Health Resources

The transcription factor Elf3, which is one of over 25 Ets family members, is expressed in a wide variety of carcinomas and has been shown to promote the transcription of many genes implicated in cancer. To understand how the Elf3 gene is regulated at the transcriptional level, we probed its 5’-flanking region, and we report here the identification of both proximal and distal regions that regulate murine Elf3 promoter activity. In addition to mapping the transcription start site of the Elf3 gene, the work described in this study identifies four cisregulatory elements in the proximal promoter region of the gene. …

N-(Methylamino) Isobutyric Acid Inhibits Proliferation Of Cfsc-2c Hepatic Stellate Cells, T. L. Freeman, G.M. Thiele, L.W. Klassen, B.T. Klassen, M.E. Mailliard

United States Public Health Resources

Activation of hepatic stellate cells (HSCs) involves the induction of ECM protein synthesis and rapid cell proliferation. Thus, agents that interfere with either process could potentially mitigate the development of liver disease by reducing the synthesis of proteins associated with fibrosis or by reducing the number of activated HSC. Previously, we described that the non-metabolizable amino acid analog N-(methylamino)isobutyric acid (MeAIB) reduced hepatic collagen content of rats in a model of CCl₄-induced liver injury, and in vitro studies using CFSC-2G cells indicated that MeAIB directly reduced collagen synthesis. However, the MeAIB-mediated reduction of hepatic collagen, in vivo, …

Environmental Risk Factors In Hospital Suicide., Daniel Z Lieberman, Harvey L P Resnik, Vicenzio Holder-Perkins

Psychiatry and Behavioral Sciences Faculty Publications

Suicide of hospitalized patients is the most common sentinel event reviewed by The Joint Commission on Accreditation of Healthcare Organizations. Shorter lengths of stay, sicker patients, and higher patient to staff ratios challenge the ability of the hospital to maintain safety. Risk factors associated with the physical environment of the inpatient psychiatric unit, cited as the most common root cause of inpatient suicide, may be neglected because evaluation of these factors is generally not included in medical education and training. Minimization of fixtures that can facilitate strangulation and other high risk aspects within the hospital environment is an important element …

Risk Of Disease From Wildlife Reservoirs: Badgers, Cattle, And Bovine Tuberculosis, M. Scantlebury, M. R. Hutchings, D. J. Allcroft, S. Harris

Michigan Bovine Tuberculosis Bibliography and Database

Livestock face complex foraging options associated with optimizing nutrient intake while being able to avoid areas posing risk of parasites or disease. Areas of tall nutrient-rich swards around fecal deposits may be attractive for grazing, but might incur fitness costs from parasites. We use the example of dairy cattle and the risks of tuberculosis transmission posed to them by pastures contaminated with badger excreta to examine this trade-off. A risk may be posed either by aerosolized inhalation through investigation or by ingestion via grazing contaminated swards. We quantified the levels of investigation and grazing of 150 dairy cows at badger …

Succession Planning In Uganda: Early Outreach For Aids-Affected Children And Their Families, Horizons Program, Makerere University Department Of Sociology, Plan Uganda

HIV and AIDS

This publication reports on an intervention study that evaluated the effectiveness of a succession planning (SP) program in Uganda. Unlike most other programs for AIDS-affected children, succession planning reaches children and their families while their HIV-positive parents are still living and in a position to plan for their children’s long-term well-being. Research carried out by the Department of Sociology at Makerere University (Kampala) and the Population Council Horizons program suggests that succession planning is a promising approach: despite AIDS-related stigma and cultural resistance to acknowledging illness and death, qualitative research indicates that the approach met with a high degree of …

HIV and AIDS

A recent Horizons study conducted jointly with two Dominican NGOs assessed the impact of two environmental-structural models in reducing HIV-related risk among female sex workers in the Dominican Republic and compared their cost-effectiveness. In the two cities studied, there were improvements from pre- to post-intervention in the key outcome variables, however the type and level of these changes varied by intervention approach. Based on our findings, program planners and policymakers involved in the study in the Dominican Republic agree that the integrated solidarity and policy model in conjunction with ongoing peer education and community mobilization activities is an appropriate, cost-effective, …

Strengthening Sti Treatment And Hiv/Aids Prevention Services In Carletonville, South Africa, Lewis Ndhlovu, Catherine Searle, Johannes Van Dam

HIV and AIDS

Although knowledge about HIV/AIDS is widespread in South Africa, adult HIV prevalence is high, indicating high levels of risky sexual behavior. Understanding the gap between knowledge and behavior requires an examination of the social context in which the epidemic occurs. The Horizons Program conducted an intervention study in the Carletonville area to study the social determinants of the HIV epidemic and to assess the impact of a targeted program of HIV and STI prevention and service delivery. In 1998, the Mothusimpilo (“Working together for health”) Intervention Project (MIP) was launched to reduce community prevalence of HIV and other STIs and …

Community Approaches And Government Policy Reduce Hiv Risk In The Dominican Republic, Deanna Kerrigan, Luis Moreno, Bayardo Gomez, Hector Jerez, Ellen Weiss, Johannes Van Dam, Eva Roca, Clare Barrington, Michael D. Sweat

HIV and AIDS

Effective programs that avert new HIV infections among sex workers and their partners, and hence the general population, are critical components of national HIV-prevention strategies. Prevention efforts have frequently relied on interventions that reach members of these vulnerable groups as individuals, such as condom promotion and STI management. Now, many researchers and program implementers are increasingly turning to “environmental-structural” interventions that address the physical, social, and political contexts in which individual behavior takes place. A recent Horizons study conducted jointly with two Dominican NGOs—Centro de Orientación e Investigación Integral and Centro de Promoción e Solidaridad Humana—and the National Program for …
