Chagas disease in New Mexico? Changes in incidence ofTrypanosoma cruziin NM Triatomines

The causative agent of Chagas disease, Trypanosoma cruzi, is transmitted by triatomine vectors. The insect is endemic in the Americas, including the United States, where epidemiological studies are limited, particularly in the Southwestern region. Here, we have determined the prevalence of T. cruzi in triatomines, and feral cats and dogs, and wild animals, the infecting parasite genotypes and the mammalian host bloodmeal sources of the triatomines at four different geographical sites in the U.S.-Mexico border, including El Paso County, Texas, and nearby cities in New Mexico. Using qualitative polymerase chain reaction to detect T. cruzi infections, we found 66.4% (n = 225) of triatomines, 45.3% (n = 95) of feral dogs, 39.2% (n = 24) of feral cats, and 71.4% (n = 7) of wild animals positive for T. cruzi. Over 95% of T. cruzi genotypes or discrete typing units (DTUs) identified were TcI and some TcIV. Furthermore, Triatoma rubida was the triatomine species most frequently (98.2%) collected in all samples analyzed. These findings suggest a high prevalence of T. cruzi infections among triatomines, and feral and wild animals in the studied sites. Therefore, our results underscore the urgent need for implementation of a systematic epidemiological surveillance program for T. cruzi infections in insect vectors, and feral and wild animals, and Chagas disease in the human population in the southwestern region of the United States.

Associated Risk Factors

Suicide is among the leading causes of death in the United States, and in women the second leading cause of injury death overall. Previous studies have suggested links between intimate partner violence and suicide in women. We examined female suicide deaths to identify and describe associated risk factors. We reviewed all reports from the New Mexico Office of the Medical Investigator for female suicide deaths occurring in New Mexico from 1990 to 1994. Information abstracted included demographics, mechanism of death, presence of alcohol/drugs, clinical depression, intimate partner violence, health problems, and other variables. Annual rates were calculated based on the 1990 census. The New Mexico female suicide death rate was 8.2/100,000 persons per year (n = 313), nearly twice the U. S. rate of 4.5/100,000. Non-Hispanic whites were overrepresented compared to Hispanics and American Indians. Decedents ranged in age from 14 to 93 years (median = 43 years). Firearms accounted for 45.7% of the suicide deaths, followed by ingested poisons (29.1%), hanging (10.5%), other (7.7%), and inhaled poisons (7.0%). Intimate partner violence was documented in 5.1% of female suicide deaths; in an additional 22.1% of cases, a male intimate partner fought with or separated from the decedent immediately preceding the suicide. Nearly two-thirds (65.5%) of the decedents had alcohol or drugs present in their blood at autopsy. Among decedents who had alcohol present (34.5%), blood alcohol levels were far higher among American Indians compared to Hispanics and non-Hispanic Whites (p = .01). Interpersonal conflict was documented in over 25% of cases, indicating that studies of the mortality of intimate partner violence should include victims of both suicide and homicide deaths to fully characterize the mortality patterns of intimate partner violence.

The suicide death rate in New Mexico is consistently higher than the national rate. Among adolescents, suicide is the third leading cause of death nationally, but in New Mexico it is the second leading cause of death. This study describes the pattern of adolescent suicide deaths in New Mexico. We conducted a retrospective review of all medical examiner autopsies for adolescent suicides (ages 20 years and younger) in New Mexico from 1990-1994. Records were reviewed for demographics and possible contributing factors such as depression, previous attempts, and alcohol and drug use. We identified 184 suicide deaths among children and adolescents ages 9-20 years for an overall rate of 12.9 per 100,000. Our rates for ages 5-9 years (0.2), 10-14 years (3.8), and 15-19 years (22.3) are over twice the U.S. rates. Suicide deaths resulted primarily from firearms (67%), hanging (16%), poisoning (6%), inhalation (4%), and other methods (7%). Method varied by ethnicity (p = .01) and gender (p = .03); males and non-Hispanic Whites were overrepresented among firearm deaths. Firearm ownership was known in 60 (48%) of the firearm deaths. Of these, 53% of the firearms belonged to a family member, 25% to the decedent, and 22% to a friend. Over one-third of decedents (41%) experienced mental disorders, primarily depressed mood and clinical depression. Previous suicide attempts were noted for 15% of the decedents. Some 50% of the decedents had alcohol or drugs present at the time of death; among American Indians/Alaska Natives, 74% had drugs or alcohol present (p = .003). Targeted interventions are needed to reduce adolescent suicide in New Mexico. We suggest raising awareness about acute and chronic contributing factors to suicide; training physicians to look for behavioral manifestations of depression; and involving physicians, teachers, and youth activity leaders in efforts to limit firearm accessibility, such as advising parents to remove firearms from their households.
