ABSTRACT
In semi-arid environments, resources necessary for survival may be unevenly distributed across the landscape. Gould's wild turkeys (Meleagris gallopavo mexicana) are spatially restricted to mountainous semi-arid areas of southwestern United States and Mexico, and information on their distribution and habitat use is limited. We described how landcover type and topographical features influenced space use and habitat selection by Gould's wild turkeys in southeastern Arizona. We used GPS data from 51 Gould's wild turkeys to describe resource selection during 2016-2017 in southeastern Arizona, USA. We estimated home ranges and calculated resource selection functions using distance from landcover types, slope, aspect, and elevation at used locations and random locations within individual home ranges. Gould's wild turkeys selected areas closer to pine forest and water. Likewise, Gould's wild turkeys selected locations with moderate elevations of 1641 ± 235 m (range = 1223-2971 m), and on north and west facing slopes with a 10° ± 8.5 (range = 0.0-67.4°) incline. Our findings suggest that conserving portions of the landscape with appropriate topography and landcover types as described above will promote habitat availability for Gould's wild turkeys.

Though mule deer (Odocoileus hemionus) persist in robust populations throughout most of their North American distribution, habitat loss, unregulated hunting, and other factors have reduced their historical range in México. Two of the 6 putative subspecies inhabiting México's deserts and Baja California peninsula are of conservation concern, occupying islands in the Pacific Ocean (Odocoileus hemionus cerrosensis on Cedros Island: endangered) and Sea of Cortés (Odocoileus hemionus sheldoni on Tiburón Island: threatened). Focusing on the desert southwest (n = 448), we sampled Tiburón (n = 22) and Cedros (n = 15) Island mule deer using contemporary samples and natural history museum specimens to complete a phylogeographic evaluation of the species complex, and assess the phylogeography of these insular subspecies. Both insular subspecies formed endemic haplotype lineages, consistent with island biogeographic theory. Bayesian skyline plots were consistent with Holocene demographic expansion. Cedros Island deer were genetically most similar to adjacent mainland Baja California deer, but exhibited a suite of unique haplotypes and reduced genetic variation. Tiburón Island deer haplotypes unexpectedly nested within a mainland lineage found in distant New Mexico, rather than the adjacent mainland Sonoran lineage. Such findings suggest the importance of postglacial climate fluctuations and biotic community turnover in the phylogeographic history of mule deer in the desert southwest. Our genetic data corroborates cultural, archaeological, and phenotypic evidence supporting Cedros and Tiburón deer endemicity and subspecies status. Reduced genetic variation, divergence from mainland populations, and demographic trends on both islands indicate that conservation, monitoring, and management are critical to ensure persistence of these endemic insular subspecies.

PROBLEM: As of December 31, 2009, an estimated 864,748 persons were living with human immunodeficiency virus (HIV) infection in the 50 U.S. states, the District of Columbia, and six U.S.-dependent areas. Whereas HIV surveillance programs in the United States collect information about persons with a diagnosis of HIV infection, supplemental surveillance systems collect in-depth information about the behavioral and clinical characteristics of persons receiving outpatient medical care for HIV infection. These data are needed to reduce HIV-related morbidity and mortality and HIV transmission. REPORTING PERIOD COVERED: Data were collected during June 2009-May 2010 for patients receiving medical care at least once during January-April 2009. DESCRIPTION OF THE SYSTEM: The Medical Monitoring Project (MMP) is an ongoing surveillance system that assesses behaviors and clinical characteristics of HIV-infected persons who have received outpatient medical care. For the 2009 data collection cycle, participants must have been aged ≥18 years and have received medical care during January-April 2009 at sampled facilities that provide HIV medical care within participating MMP project areas. Behavioral and selected clinical data were collected using an in-person interview, and most clinical data were collected using medical record abstraction. A total of 23 project areas in 16 states and Puerto Rico were funded to collect data during the 2009 data collection cycle. The data were weighted for probability of selection and nonresponse to be representative of adults receiving outpatient medical care for HIV infection in the United States and Puerto Rico. Prevalence estimates are presented as weighted percentages. The period of reference is the 12 months before the patient interview unless otherwise noted. RESULTS: The patients in MMP represent 421,186 adults who received outpatient medical care for HIV infection in the United States and Puerto Rico during January-April 2009. Of adults who received medical care for HIV infection, an estimated 71.2% were male, 27.2% were female, and 1.6% were transgender. An estimated 41.4% were black or African American, 34.6% were white, and 19.1% were Hispanic or Latino. The largest proportion (23.1%) were aged 45-49 years. Most patients (81.1%) had medical coverage; 40.3% had Medicaid, 30.6% had private health insurance, and 25.7% had Medicare. An estimated 69.6% of patients had three or more documented CD4+ T-lymphocyte cell (CD4+) or HIV viral load tests. Most patients (88.7%) were prescribed antiretroviral therapy (ART), and 71.6% had a documented viral load that was undetectable or ≤200 copies/mL at their most recent test. Among sexually active patients, 55.0% had documentation in the medical record of being tested for syphilis, 23.2% for gonorrhea, and 23.9% for chlamydia. Noninjection drugs were used for nonmedical purposes by an estimated 27.1% of patients, whereas injection drugs were used for nonmedical purposes by 2.1% of patients. Overall, 12.9% of patients engaged in unprotected sex with a partner of negative or unknown HIV status. Unmet supportive service needs were prevalent, with an estimated 22.8% in need of dental care and 12.0% in need of public benefits, including Social Security Income or Social Security Disability Insurance. Fewer than half of patients (44.8%) reported receiving HIV and sexually transmitted disease prevention counseling from a health-care provider. INTERPRETATION: The findings in this report indicate that most adults living with HIV who received medical care in 2009 were taking ART, had CD4+ and HIV viral load testing at regular intervals, and had health insurance or other coverage. However, some patients did not receive clinical services and treatment in accordance with guidelines. Some patients engaged in behaviors, such as unprotected sex, that increase the risk for transmitting HIV to sex partners, and some used noninjection or injection drugs or both. PUBLIC HEALTH ACTIONS: Local and state health departments and federal agencies can use MMP data for program planning to determine allocation of services and resources, guide prevention planning, assess unmet medical and supportive service needs, inform health-care providers, and help focus intervention programs and health policies at the local, state, and national levels.

BACKGROUND: A World Health Organization (WHO) case management approach has been used to identify and treat children with pneumonia worldwide since 1987. Many children are treated repeatedly: 23% of children with pneumonia in our rural Haitian district had met the WHO criteria on two or more occasions; but underlying disease in such children has not been systematically studied. METHODS: We enrolled 103 children who had been diagnosed with pneumonia on 3 or more occasions by community health workers using WHO criteria. We compared them with 138 children similarly evaluated but never diagnosed with pneumonia, matching by health worker and age. We administered questionnaires to parents and performed complete physical examinations, tuberculin skin tests and serologic testing for HIV on all subjects and chest radiographs on case children. RESULTS: Two percent of case children and 1.5% of controls had positive tuberculin skin test reactions. None of the children tested was HIV-seropositive. Ninety-four case children had normal baseline chest radiographs and three had focal infiltrates. A history of wheezing was reported for 79% of case children and 61% of controls (P = 0.002), and wheezing with exercise was reported for 36% and 22%, respectively (P = 0.02). DISCUSSION: Most children in Haiti with recurrent pneumonia diagnosed by WHO criteria do not have evidence of tuberculosis, HIV infection or pulmonary anomalies, but they may be more likely to have asthma, and this should be considered as an alternative diagnosis. This information should help direct evaluation of such children in other settings and prompt further study of asthma in developing countries.
