Association between heroin use, needle sharing and tattoos received in prison with hepatitis B and C positivity among street-recruited injecting drug users in New Mexico, USA.

This study aimed to assess the seroprevalence and risk factors for hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV-1 infections among injecting drug users (IDU) in New Mexico. Serological and behavioural surveys were conducted in conjunction with street-based outreach, education and HIV counselling and testing. High rates of antibody positivity for HCV (82.2%) and HBV (61.1%), and a low rate for HIV (0.5%) were found. In multivariate analyses, both HBV and HCV infection were positively associated with increasing age, increasing years of injection and heroin use. Receipt of a tattoo in prison/jail was associated with HBV (odds ratio = 2.3, 95% confidence interval 1.4, 3.8) and HCV (OR = 3.4, 95% CI = 1.6, 7.5) infections. Prevention of bloodborne pathogens among IDUs should focus on young users, early in their drug use experience. Studies examining the relationship between tattooing and HBV and HCV infection are needed as are efforts to promote sterile tattooing, in prisons and elsewhere.

Psoroptic scabies in bignorn sheep (Ovis canadensis mexicana) in New Mexico.

Prior to 1978, no reports were made of scabies lesions or mites recovered from any Mexican bighorn sheep (Ovis canadensis mexicana) examined in the San Andres National Wildlife Refuge in southern New Mexico. In 1978, all of five rams harvested by hunters had live mites of the genus Psoroptes and active lesions of scabies in their ears and/or on their bodies. Deaths due to scabies were not documented during this outbreak although aerial helicopter surveys conducted in March, June and September, 1979 recorded less than half the sheep observations of five previous and similarly conducted surveys. After measurement of the length of the outer opisthosomal setae of the male mites, they appear to be Psoroptes ovis (Hering), the common scabies mite of domestic sheep, cattle and horses. Final specific determination must await proposed transmission studies with domestic livestock.

Lung cancer risk and vitamin A consumption in New Mexico.

The association between dietary intake of vitamin A and lung cancer risk was examined in a population-based, case-control study of 447 patients and 759 control subjects in New Mexico. A food frequency interview was used to measure usual consumption of total vitamin A retinol, preformed vitamin A, and carotene. With all respondents combined, the odds ratios for lung cancer increased as intakes of total vitamin A and carotene declined but did not vary with intake of preformed vitamin A. When the subjects were stratified by ethnic group, Hispanic or non-Hispanic (Anglo) white, significant effects of vitamin A consumption were limited to the Anglos. In the Anglos, the protective effects of total vitamin A and carotene consumption were present in males and females, but varied strongly with cigarette smoking habits. In Anglo smokers, significant increases in the odds ratios with declining intake were observed in former but not in current smokers. Among the former smokers, significant effects of total vitamin A and carotene consumption were present only in those who had stopped smoking for 6 to 15 yr. Limitation of the protective effect of vitamin A and carotene consumption to past smokers has important implications for the design of clinical trials and for cancer control strategies.

Helping elderly participants keep 3-day diet records in the New Mexico Aging Process Study.

Although verbal and written instructions on how to record dietary intake are commonly used in research, little information has been published describing instructional methods or materials. In the New Mexico Aging Process Study, a longitudinal study of nutrition and aging, participants keep a 3-day diet record each year. Classroom instruction and written materials are used in the study, and they were updated for use with Food Intake Analysis System (FIAS), version 2.3. This article describes the instructional methods and materials used to prepare elderly participants to keep accurate diet records; reports the development of a novel instructional tool, the food description flowcharts; and presents participants' opinions of the quality of the instruction and the usefulness of written materials. Included in the written materials were general instructions for recording food intake, examples of completed food intake and recipe forms, hints for eating out, and instructions for easy-to-use electronic scales. The flowcharts guide participants in accurately describing food intake while matching the coding requirements of FIAS. Fifty participants completed a written survey to evaluate the instructions and written materials. More than half of the respondents found the written materials to be very useful. All found the verbal instruction to be excellent or good. Nutritionists observed that records kept by participants who attended the class were generally complete and specific. The findings indicate that participants were satisfied with the instructions and written materials.

Rural-urban health care provider disparities in Alaska and New Mexico.

Compared to their urban counterparts, rural residents face numerous disparities in obtaining health care, including limited access to care providers. We assessed disparities in provider availability in rural versus urban Alaska and New Mexico, with emphasis on professionals likely to provide mental health care. Using lists of licenses, we categorized physical and mental health care providers into rural versus urban and calculated rural versus urban disparity ratios. Rural residents had significantly less access to health care providers and discrepancies grew with level of required provider education and specialization. Addressing disparities via creative strategies is crucial to improving rural care delivery.

Background radioactivity in sediments near Los Alamos, New Mexico.

River and reservoir sediments have been collected annually by Los Alamos National Laboratory since 1974 and 1979, respectively. These background samples are collected from five river stations and four reservoirs located throughout northern New Mexico and southern Colorado. Analyses include 3H, 90Sr, 137Cs, total U, 238Pu, 239,240Pu, 241Am, gross alpha, gross beta, and gross gamma radioactivity. Surprisingly, there are no federal or state regulatory standards in the USA that specify how to compute background radioactivity values on sediments. Hence, the sample median (or 0.50 quantile) is proposed for this background because it reflects central data tendency and is distribution-free. Estimates for the upper limit of background radioactivity on river and reservoir sediments are made for sampled analytes using the 0.95 quantile (two-tail). These analyses also show that seven of ten analytes from reservoir sediments are normally distributed, or are normally distributed after a logarithmic or square root transformation. However, only three of ten analytes from river sediments are similarly distributed. In addition, isotope ratios for 137Cs/238Pu, 137Cs/239,240Pu, and 239,240Pu/238Pu from reservoir sediments are independent of clay content, total organic carbon/specific surface area (TOC/SSA) and cation exchange capacity/specific surface area (CEC/SSA) ratios. These TOC/SSA and CEC/SSA ratios reflect sediment organic carbon and surface charge densities that are associated with radionuclide absorption, adsorption, and ion exchange reactions on clay mineral structures. These latter ratio values greatly exceed the availability of background radionuclides in the environment, and insure that measured background levels are a maximum. Since finer-grained reservoir sediments contain larger clay-sized fractions compared to coarser river sediments, they show higher background levels for most analytes. Furthermore, radioactivity values on reservoir sediments have remained relatively constant since the early 1980s. These results suggest that clay contents in terrestrial sediments are often more important at concentrating background radionuclides than many other environmental factors, including geology, climate and vegetation. Hence, reservoirs and floodplains represent ideal radionuclide sampling locations because fine-grained materials are more easily trapped here. Ultimately, most of these differences still reflect spatial and temporal variability originating from global atmospheric nuclear weapons testing and disintegration of nuclear-powered satellites upon atmospheric reentry.

Outcomes of teen parenting programs in New Mexico.

Although teen pregnancy rates in the U.S. have recently declined, the need for programs for pregnant and parenting teens remains. This report presents information from 53 programs that served pregnant and parenting teens in New Mexico between 1997 and 2000. Data on 3,194 teens, including their characteristics, the services they received, and several key outcomes, are examined. These data indicate that the programs were successful in promoting educational attainment as well as gains in employment. Prevalence of late prenatal care and low birth weight babies was lower than statewide averages, and the rate of repeat pregnancy was lower than that reported by many other programs. How these programs achieved these results is discussed.

Variation in recommendations for cancer screening among primary care physicians in New Mexico.

The acceptance of age-appropriate cancer screening as an integral part of primary care has grown among physicians over the past decade. We conducted a mailed survey of all primary care physicians in New Mexico in order to better understand their current cancer screening practices. We found a high rate of self-reported screening, particularly for prostate and colorectal cancer. The screening rates were influenced only slightly by the introduction of evidence-based guidelines, with younger physicians and those with university affiliations more likely to follow recommendations. Female physicians and obstetrician-gynecologists endorsed breast and cervical cancer screening among all age groups and were less likely to follow recommendations for less frequent screening in women as they age. Since a physician's practice beliefs influence his/her attitude toward testing, tailoring education by physician specialty may be more effective than using generic messages in encouraging compliance with the most recent evidence-based guidelines.

Hydrocarbons and aromatic hydrocarbons in groundwater surrounding an earthen waste disposal pit for produced water in the Duncan oil field of New Mexico.

Samples of groundwater and soil were collected from test pits placed 25 m intervals on five axes extending from an earthen waste disposal pit for produced water near the San Juan River of northwest New Mexico. Samples were obtained at depths of 1.2 to 1.5 m and were analyzed using GC and GC/MS techniques for purgable hydrocarbons, including benzenes, and for solvent extractable organic compounds. Water samples from test pits down-gradient from the disposal pit contained purgable and extractable hydrocarbons that were similar to contents of the waste disposal pit. In contrast, water samples obtained from test pits up-gradient from the waste pit were free of detectable organic components. Major purgable components in the waste pit and in surrounding groundwater included saturated/unsaturated hydrocarbons and aromatic/alkylated aromatic hydrocarbons. Samples collected 25 m from the waste pit contained concentrations of all compounds greater than in samples taken at 50 m in distance on the same exis. Total concentration of purgable aromatic hydrocarbons in groundwater from test plots ranged from a high of 200 ppb at 25 m, to a low of 12 ppb at 50 m on an axis through the plume center.

Survival after cancer surgery of elderly patients in New Mexico, 1969-1982.

To examine the effects of advancing age, sex, and ethnicity on estimated 30-day survival after surgery for cancer, we reviewed population-based data on 16,130 cancer cases collected by the New Mexico Tumor Registry from 1969-1982. For surgery at most sites, mortality increased with increasing age. The highest mortality was observed for sites requiring laparotomy or thoracotomy. Sex and ethnicity (Hispanic versus non-Hispanic white) had little effect on short-term survival. Comparison of short-term survival for two time periods, 1969-1975 and 1976-1982, showed a strong trend of improving survival for many sites.

Respiratory disease mortality in New Mexico's American Indians and Hispanics.

To determine the effect of ethnic group on respiratory disease occurrence, average annual sex, ethnic, and disease specific mortality rates for the period of 1969 to 1977 were calculated for New Mexico's American Indian, Hispanic, and Anglo populations. Incidence data were available for respiratory tract cancer. This study corroborates previous findings of reduced mortality from lung cancer in American Indians of both sexes and in Hispanic males. American Indian mortality from tuberculosis and from influenza and pneumonia was high. Hispanic males and American Indians of both sexes showed low mortality rates for chronic obstructive pulmonary disease (COPD). Differing cigarette usage is the most obvious explanation for the variations in COPD and lung cancer occurrence with ethnic group.

Predictors of conviction and sentencing of DWI offenders in a New Mexico County.

OBJECTIVE: To analyze predictors of conviction and dismissal of individuals charged with DWI, and predictors of the sentences of those who are convicted. METHODS: Data come from the Citation Tracking System of the State of New Mexico's Motor Vehicle Division and includes information on all individuals who were arrested for DWI in San Juan County between August 1994 and December 2000. Independent variables were: age, gender, race/ethnicity, waiver of right to an attorney, court of arraignment, year of arrest, BAC, and number of prior DWI arrests. Dependent variables were: (1) conviction or dismissal, (2) jail or no jail, (3) incarceration/treatment or not, (4) fine or no fine, (5) length of jail sentence, (6) waived right of attorney, and (7) magnitude of fine. Multiple linear and logistic regression was used in the analyses. RESULTS: Use of an attorney is associated with reduced likelihood of conviction and, if convicted, in reduced likelihood of jail sentence and reduced jail time, but greater likelihood and magnitude of a fine. Native Americans were more likely than Hispanics and non-Hispanic whites to waive their right to an attorney. Native Americans were most likely to be sentenced to the detention/treatment program. BAC and number of prior arrests were each positively associated with increased likelihood of conviction and more severe sentences. There is also substantial variability in severity of sentencing among courts. CONCLUSION: Likelihood of conviction and severity of sentences are both determined by extra-legal factors, resulting in inconsistent application of the law. This may in turn contribute to a lack of compliance with laws related to DWI.

Experimental evaluation of rodent exclusion methods to reduce hantavirus transmission to residents in a Native American community in New Mexico.

We conducted a pilot study to evaluate the efficacy of rodent proofing continuously occupied homes as a method for lowering the risk for hantavirus pulmonary syndrome (HPS) among residents of a Native American community in northwestern New Mexico. Rodent proofing of dwellings was paired with culturally appropriate health education. Seventy homes were randomly assigned to treatment or control categories. Treatment homes were rodent-proofed by sealing openings around foundations, doors, roofs, and pipes and repairing screens and windows. Repairs to each dwelling were limited to $500 US. After repairs were completed, 15-20 snap traps were placed in each treatment and control home and checked approximately every 2 days for an average of 3-4 weeks. During 23,373 trap nights, one house mouse (Mus musculus) was captured in one treatment home, and 20 mice (16 deer mice, Peromyscus maniculatus, two Pinyon mice, Peromyscus truei, and two unidentified mice) were captured in five control homes (one house had 14 captures, two had two captures, and two had one capture). Trap success was 0.01% in treatment homes and 0.15% in controls. Intensity of infestation (mean number of mice captured per infested home) was 1 in treatment homes and 4 in controls. Observations of evidence of infestation (feces, nesting material, gnaw marks, or reports of infestation by occupant) per 100 days of observation were 1.2 in treatment homes and 3.1 in controls. Statistical power of the experiment was limited because it coincided with a period of low rodent abundance (August-November 2000). Nevertheless, these results suggest that inexpensive rodent proofing of occupied rural homes can decrease the frequency and intensity of rodent intrusion, thereby reducing the risk of HPS among rural residents in the southwestern United States.

Lung cancer and occupation in New Mexico.

The association between occupation and lung cancer risk was examined in a population-based, case-control study of 506 patients (333 males and 173 females) and 771 control (499 males and 272 females) subjects in New Mexico. A personal interview was used to obtain lifetime occupational and smoking histories and self-reported history of exposures to specific agents. High-risk jobs were identified in advance of data analysis and linked with industrial and occupational codes for hypothesis testing. For females, lung cancer risk was not associated with employment history, but power was limited. For males, elevated risks were found for the uranium mining industry [odds ratio (OR) = 1.9; 95% confidence internal (CI) = 0.8-4.9], underground miners (OR = 2.1; 95% CI = 1.1-3.7), painters (OR = 2.7; 95% CI = 0.8-8.9), and welders (OR = 3.2; 95% CI = 1.4-7.4). For self-reported exposure to any of 18 agents, only the OR for exposure to "other metals" was elevated. The population attributable risk in males was estimated as 14% for employment in any high-risk industry or occupation with an OR above 1 in this study.

Smokeless tobacco consumption by Mexican-Americans and Anglo-Americans in southwestern New Mexico.

A telephone survey was conducted to compare the extent of smokeless tobacco consumption by Anglo-Americans and Mexican-Americans. Using systematic random sampling, one out of every 25 phone numbers was selected from the Grant County, New Mexico, telephone directory. Two hundred and ten individuals were interviewed. All of the female respondents, including 46 Mexican-Americans and 81 Anglo-Americans, indicated that they did not use smokeless tobacco. Twenty-five percent of the 51 Anglo-American males and 26% of the 30 Mexican-American males identified themselves as consumers of smokeless tobacco. A chi-square analysis revealed no significance difference between the number of Mexican-Americans and Anglo-Americans among the male self-identified users of smokeless tobacco.

Survival of children and adolescents with acute lymphoid leukemia. A study of American Indians and Hispanic and non-Hispanic whites treated in New Mexico (1969 to 1986).

During the period 1969 to 1986, 196 American Indian and Hispanic and non-Hispanic white children and adolescents (ages, 0 to 19 years) were treated for acute lymphoid leukemia (ALL) at the University of New Mexico affiliated institutions. There were 28 American Indians (14%), 91 Hispanic whites (46%), and 77 non-Hispanic whites (39%). Median survivals for patients undergoing antileukemic therapy ranged from 8 months for American Indian boys to 140 months for non-Hispanic white girls. American Indian boys had the highest initial median leukocyte count (WBC) at 23.8 X 10(9)/l. Compliance problems occurred most commonly among American Indian children of both genders. Other clinical and pathologic features evaluated in this study were distributed similarly among the ethnic gender groups. Multi-variate analysis revealed that independent prognostic variables for survival included initial WBC, age, and gender. Ethnicity and compliance problems were possible, but confounded, prognostic variables. To the authors' knowledge this represents the most comprehensive study to date of ALL in American Indian patients.
