A Comprehensive COVID-19 Daily News and Medical Literature Briefing to Inform Health Care and Policy in New Mexico: Implementation Study.

BACKGROUND: On March 11, 2020, the New Mexico Governor declared a public health emergency in response to the COVID-19 pandemic. The New Mexico medical advisory team contacted University of New Mexico (UNM) faculty to form a team to consolidate growing information on severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its disease to facilitate New Mexico's pandemic management. Thus, faculty, physicians, staff, graduate students, and medical students created the "UNM Global Health COVID-19 Intelligence Briefing." OBJECTIVE: In this paper, we sought to (1) share how to create an informative briefing to guide public policy and medical practice and manage information overload with rapidly evolving scientific evidence; (2) determine the qualitative usefulness of the briefing to its readers; and (3) determine the qualitative effect this project has had on virtual medical education. METHODS: Microsoft Teams was used for manual and automated capture of COVID-19 articles and composition of briefings. Multilevel triaging saved impactful articles to be reviewed, and priority was placed on randomized controlled studies, meta-analyses, systematic reviews, practice guidelines, and information on health care and policy response to COVID-19. The finalized briefing was disseminated by email, a listserv, and posted on the UNM digital repository. A survey was sent to readers to determine briefing usefulness and whether it led to policy or medical practice changes. Medical students, unable to partake in direct patient care, proposed to the School of Medicine that involvement in the briefing should count as course credit, which was approved. The maintenance of medical student involvement in the briefings as well as this publication was led by medical students. RESULTS: An average of 456 articles were assessed daily. The briefings reached approximately 1000 people by email and listserv directly, with an unknown amount of forwarding. Digital repository tracking showed 5047 downloads across 116 countries as of July 5, 2020. The survey found 108 (95%) of 114 participants gained relevant knowledge, 90 (79%) believed it decreased misinformation, 27 (24%) used the briefing as their primary source of information, and 90 (79%) forwarded it to colleagues. Specific and impactful public policy decisions were informed based on the briefing. Medical students reported that the project allowed them to improve on their scientific literature assessment, stay current on the pandemic, and serve their community. CONCLUSIONS: The COVID-19 briefings succeeded in informing and guiding New Mexico policy and clinical practice. The project received positive feedback from the community and was shown to decrease information burden and misinformation. The virtual platforms allowed for the continuation of medical education. Variability in subject matter expertise was addressed with training, standardized article selection criteria, and collaborative editing led by faculty.

Willingness of women to participate in obstetrical and pediatric research involving biobanks.

Use of biobanks for future genetic/genomic testing has increased. Biospecimens are increasingly being collected from infants/children; however, little is known about attitudes towards collection of biospecimens from postpartum women and their child. Using a hypothetical consent, this study investigated willingness to participate and attitudes, beliefs, and concerns related to consent materials requesting the biobanking genetic samples. A cross-sectional mixed methods design included women who reviewed a hypothetical consent related to biobanking genetic samples. Women were asked about their willingness to participate, followed by a focus group about biobanks and genetic/genomic testing. Post-focus group questionnaires assessed willingness to participate, the influence of study characteristics, and attitudes about genetic testing. Women (N = 37) were 29.0± 7.3 years of age (range 19-44); 51% had children and 28% were currently pregnant. A total of 46% were Hispanic (H), 38% were White non-Hispanic (WNH), and 16% were Native American (NA). Seventy-six percent (28/37) initially indicated that they would participate in the hypothetical study. Race and ethnicity impacted whether women would participate. Fewer NA women indicated that they would participate compared with H women and with WNH women (p < 0.02). Age, pregnancy status, having children, education level, insurance status, and income had no impact on participation decision and willingness to biobank specimens. NA and H women indicated that they were less likely than WNH women to agree to participate in a long-term biobank study. Given the importance of determining the genetic influence of health and disease, it is critical to attend to the questions and concerns of minority women regarding genetic studies.

Cryptosporidium infection, onsite wastewater systems and private wells in the arid Southwest.

Few prior studies have examined the potential health risks from transmission of enteric parasites via aquifers contaminated by wastewater from onsite systems. A cross-sectional study of 600 residents in households served with either onsite wastewater systems and private wells or city sewer/water systems in three different sites in central New Mexico compared serological responses to Cryptosporidium, a common waterborne infections agent. Study participants completed a short self-administered questionnaire with questions on demographic characteristics, characteristics of the onsite wastewater system and private well, and common risk factors associated with cryptosporidiosis. A sample of household tap water was collected, as well as a blood sample from each study participant to measure IgG responses to antigen groups for Cryptosporidium. Logistic regression analysis showed a significant association between having an onsite wastewater system and private well and the 27-kDa marker for Cryptosporidium in the River Valley site after adjusting for covariates (OR = 1.98; 95% CI = 1.11-3.55). This study, together with one prior study, suggests that the presence of onsite wastewater systems and private wells might be associated with an increased risk of Cryptosporidium infection.

Reuniting public health and medicine: the University of New Mexico School of Medicine Public Health Certificate.

The University of New Mexico School of Medicine (UNMSOM) sought to train medical students in public health concepts, knowledge, and skills as a means of improving the health of communities statewide. Faculty members from every UNMSOM department collaborated to create and integrate a public health focus into all years of the medical school curriculum. They identified key competencies and developed new courses that would synchronize students' learning public health subjects with the mainstream medical school content. New courses include: Health Equity: Principles of Public Health; Epidemiology and Biostatistics; Evidence-Based Practice; Community-Based Service Learning; and Ethics in Public Health. Students experiencing the new courses, first in pilot and then final forms, gave high quantitative ratings to all courses. Some students' qualitative comments suggest that the Public Health Certificate has had a profound transformative effect. Instituting the integrated Public Health Certificate at UNMSOM places it among the first medical schools to require all its medical students to complete medical school with public health training. The new UNMSOM Public Health Certificate courses reunite medicine and public health in a unified curriculum.

A community integration approach to social determinants of health in New Mexico.

Lifestyle and Values Impacting Diabetes Awareness (LA VIDA), a community-based diabetes intervention program targeting Hispanics in southwestern New Mexico, addresses social determinants of health by utilizing promotores and collaborating with community partners and health care providers. Using a mixed-methods approach, a program evaluation documented the promotores' crucial role in providing social support, contributing to social cohesion, and accessing health care, community resources, and LA VIDA's educational and healthy lifestyle activities. Findings suggest that patients with diabetes who participated in the LA VIDA program significantly increased the number of days they checked their feet and took their diabetes medications and significantly lowered their glycated hemoglobin levels.

Enteric illness risks before and after water treatment improvements.

This study evaluated whether occurrence of acute gastrointestinal illnesses declined after filtration and ozonation were added to a previously unfiltered, chlorinated high-quality surface water source in a northwest United States city. Enteric and other illnesses were recorded for two 6-month periods for control and intervention sites in the same city. During phase 1, chlorinated, unfiltered drinking water for both sites was obtained from protected watersheds. During phase 2, the intervention site received chlorinated, filtered and ozonated drinking water. The water was not altered in the control site. No overall differences were found in the risk of any of the illnesses after the new water treatment plant was completed. There was a significantly increased risk of diarrhoea and highly credible gastrointestinal illness in participants with three or more episodes of the same type of illness during phase 1.

Influenza and COPD mortality protection as pleiotropic, dose-dependent effects of statins.

BACKGROUND: Published data on antiinflammatory and immunomodulatory effects of statins suggest they may reduce mortality risks associated with an unchecked immune response to selected infections, including influenza and COPD. We assessed whether statin users had reduced mortality risks from these conditions. METHODS: We conducted a matched cohort study (n = 76,232) and two separate case-control studies (397 influenza and 207 COPD deaths) to evaluate whether statin therapy is associated with increased or decreased mortality risk and survival time using health-care encounter data for members of health maintenance organizations. For the cohort study, baseline illness risks from all causes prior to initiation of statin therapy were used to statistically adjust for the occurrence of outcomes after initiation of treatment. RESULTS: For moderate-dose (>/= 4 mg/d) statin users, this cohort study found statistically significant reduced odds ratios (ORs) of influenza/pneumonia death (OR, 0.60; 95% confidence interval [CI], 0.44 to 0.81) and COPD death (OR, 0.17; 95% CI, 0.07 to 0.42) and similarly reduced survival hazard ratios. Findings were confirmed with the case-control studies. Confounding factors not considered may explain some of the effects observed. CONCLUSIONS: This study found a dramatically reduced risk of COPD death and a significantly reduced risks of influenza death among moderate-dose statin users.

Protective immunity associated with a strong serological response to a Cryptosporidium-specific antigen group, in HIV-infected individuals.

This study assessed whether serological responses to Cryptosporidium antigens are associated with a reduced risk of diarrheal illness in cases of infection with human immunodeficiency virus (HIV). The association between serological responses to the Cryptosporidium 15/17-kDa and 27-kDa antigen groups and reported diarrheal illness was examined by use of data from a previously published study of cases of HIV infection. In immunosuppressed individuals, a strong serological response to the 27-kDa antigen group was associated with a reduced risk of diarrhea without weight loss. This finding suggests that acquired protective immunity to cryptosporidiosis may be important in controlling the burden of cryptosporidiosis in immunosuppressed individuals.

Arsenic-induced skin conditions identified in southwest dermatology practices: an epidemiologic tool?

Populations living in the Southwest United States are more likely to be exposed to elevated drinking water arsenic levels compared to other areas of the country. Skin changes, including hyperpigmentation and generalized hyperkeratosis, are the most common signs of chronic arsenic ingestion from drinking water. The purpose of this study was to determine the feasibility of using dermatology practices in New Mexico, Arizona, and western Texas as a surveillance system for arsenical skin disorders related to drinking water. Postcard questionnaires were mailed to practicing dermatologists. The number of cases of arsenical hyperpigmentation/keratoses seen by these dermatologists during the past 10 years and the past year were estimated. Of 240 dermatologists who were mailed questionnaires, 37 reported seeing 237 patients with arsenical hyperpigmentation/keratoses in the past 10 years and 35 patients in the past year. Since approximately one-eighth of dermatologists practicing in the Southwest saw at least one patient with arsenical hyperpigmentation/keratoses during one year, it appears feasible to complete a population-based study of these conditions.

How clean must our drinking water be: the importance of protective immunity.

BACKGROUND: Cryptosporidium parvum is an important cause of epidemic diarrhea. Few studies have assessed whether serological evidence of prior infection in adults is related to a reduced occurrence of enteric illness. METHODS: Serum samples and enteric illness event data were obtained in 2000 and 2001 from 326 people served by 1 of 2 unfiltered surface sources or 1 groundwater source. In 2001, filtration was initiated at 1 of the surface sources. Poisson regression related illness episodes with serological responses to the 15/17- and 27-kDa Cryptosporidium antigen groups. RESULTS: Subjects with moderately strong responses to the 15/17-kDa antigen had <65% of the risk of all 1-3-day episodes of diarrheal or gastrointestinal illness and <40% of the risk of all >/=4-day episodes, compared with subjects without a moderately strong response. Water source, change in water treatment, and very weak responses were unrelated to illness events. CONCLUSIONS: Endemic Cryptosporidium infections are a common cause of diarrheal and gastrointestinal illness in persons without a moderately strong response to the 15/17-kDa antigen group. Users of surface-derived drinking water are more likely to have strong serological responses to this antigen group and may be at a lower risk of endemic gastrointestinal illness caused by Cryptosporidium infection.

Family history, Hispanic ethnicity, and prostate cancer risk.

Family history is known to be a prostate cancer (CaP) risk factor for non-Hispanic Whites (NHWs) and African Americans, but little data are available on the risk for Hispanics (Hs). This population-based case-control study used mailed surveys to assess the effects of ethnicity and family history of CaP on CaP risk in Hs and NHWs. Cases (N = 351) were those identified by the New Mexico Tumor Registry as having been newly diagnosed with CaP from October 1, 1994 to October 31, 1995. Controls (N = 618) were randomly selected and frequency-matched to cases by ethnicity and 5-year age groups. Multivariate analyses were conducted using conditional logistic regression. After controlling for age, education, and income in the models, positive family history increased risk for both Hispanics (H) (OR 2.7, 95% CI 1.5-4.7) and non-Hispanic Whites (NHW) (OR 2.0, 95% CI 1.3-3.1), suggesting that having a family history of CaP is a risk factor for both ethnic groups.

Identifying US populations for the study of health effects related to drinking water arsenic.

The US Environmental Protection Agency recently set a new maximum contaminant level (MCL) for arsenic in drinking water of 10 micro g/l. In this paper, we review the completeness and accuracy of drinking water arsenic occurrence data in the United States and identify populations exposed to elevated arsenic concentrations that would be suitable for epidemiological studies of arsenic health effects. Using existing data from the Environmental Protection Agency Arsenic Occurrence and Exposure Database and additional data from state health and environment departments and water utilities, we identified 33 counties in 11 states with an estimated mean drinking water arsenic concentration of 10 micro g/l or greater. A total of 11 of these 'confirmed' counties had an estimated mean arsenic concentration of 20 micro g/l or more and two had an estimated mean arsenic concentration 50 micro g/l or more. Based on census data, between 1950 and 1999 there were approximately 51.1 million person-years of exposure to drinking water arsenic at levels of 10 micro g/l or more, 8.2 million at levels of 20 micro g/l or more arsenic and 0.9 million at levels of 50 micro g/l or more. Mortality and incidence of diseases known to be associated with arsenic exposure can and should be examined in these counties as part of a comprehensive assessment of arsenic health effects in US populations.

Mortality among children residing near the American Smelting and Refining Company (ASARCO) copper smelter in Ruston, Washington.

A retrospective cohort study was undertaken to determine whether childhood exposure to ambient arsenic was associated with increased mortality rates. Cohort members comprised children who had lived within 4.0 km (2.5 mi) of the American Smelting and Refining Company (ASARCO) copper smelter and arsenic refinery in Ruston, Washington, for at least 2 yr during the time period from 1907 to 1932. The cohort included 1,827 boys and 1,305 girls identified from school census records. Exposure intensity was computed as the total number of years a child had lived at a residence less than 1.6 km (1.0 mi) from the smelter stack during the study period. In only one exposure intensity group (i.e., residence > or = 10.0 yr less than 1.6 km [1.0 mi] from the smelter) for boys were Cox proportional hazards ratios significantly higher than 1.00: for all causes of death (1.52), ischemic heart disease (1.77), and external causes (1.93). For girls, hazard ratios were not elevated significantly for any cause of death in any exposure intensity group.
