A case-control study of risk factors for Haemophilus influenzae type B disease in Navajo children. (1/706)
To understand the potential risk factors and protective factors for invasive Haemophilus influenzae type b (Hib) disease, we conducted a case-control study among Navajo children less than two years of age resident on the Navajo Nation. We analyzed household interview data for 60 cases that occurred between August 1988 and February 1991, and for 116 controls matched by age, gender, and geographic location. The Hib vaccine recipients were excluded from the analyses. Conditional logistic regression models were fit to examine many variables relating to social and environmental conditions. Risk factors determined to be important were never breast fed (odds ratio [OR] = 3.55, 95% confidence interval [CI] = 1.52, 8.26), shared care with more than one child less than two years of age (OR = 2.32, 95% CI = 0.91, 5.96); wood heating (OR = 2.14, 95% CI = 0.91, 5.05); rodents in the home (OR = 8.18, 95% CI = 0.83, 80.7); and any livestock near the home (OR = 2.18, 95% CI = 0.94, 5.04). (+info)Long-term hantavirus persistence in rodent populations in central Arizona. (2/706)
For 35 months, we monitored hantavirus activity in rodent populations in central Arizona. The most frequently captured hantavirus antibody-positive rodents were Peromyscus boylii and P. truei. Antibody-positive P. boylii were more frequently male (84%), older, and heavier, and they survived longer on trapping web sites than antibody-negative mice. The number of antibody-positive P. boylii was greater during high population densities than during low densities, while antibody prevalence was greater during low population densities. Virus transmission and incidence rates, also related to population densities, varied by trapping site. The spatial distribution of antibody-positive P. boylii varied by population density and reflected the species preference for dense chaparral habitats. The focal ranges of antibody-positive P. boylii also demonstrated a patchy distribution of hantavirus. (+info)A longitudinal study of Sin Nombre virus prevalence in rodents, southeastern Arizona. (3/706)
We determined the prevalence of Sin Nombre virus antibodies in small mammals in southeastern Arizona. Of 1,234 rodents (from 13 species) captured each month from May through December 1995, only mice in the genus Peromyscus were seropositive. Antibody prevalence was 14.3% in 21 white-footed mice (P. leucopus), 13.3% in 98 brush mice (P. boylii), 0.8% in 118 cactus mice (P. eremicus), and 0% in 2 deer mice (P. maniculatus). Most antibody-positive mice were adult male Peromyscus captured close to one another early in the study. Population dynamics of brush mice suggest a correlation between population size and hantavirus-antibody prevalence. (+info)Effect of home blood glucose monitoring on the management of patients with non-insulin dependent diabetes mellitus in the primary care setting. (4/706)
The purpose of the study was to determine whether blood glucose monitoring strips influence the management of patients with non-insulin dependent diabetes (NIDDM) in the primary care setting. The medical records of 115 patients with NIDDM taking a sulfonylurea drug (oral hypoglycemic agent) during the review period were randomly selected for review. Patients were divided into two groups: those who did not receive a prescription for blood glucose monitoring strips during 1995 and 1996 and those who did for the same 2 years. The main outcome measures were hemoglobin A1c, blood sugar, number of laboratory tests ordered, and number and type of treatment interventions. No statistically significant differences between groups were noted for any measured parameter. Glucose control was independent of number of strips dispensed. Home glucose monitoring strips did not affect the management of patients with NIDDM taking a sulfonylurea agent in the primary care setting.

CIGNA Healthcare of Arizona is using a computerized patient record system (EpicCare) for all medical care delivery at two primary care clinics. Use of this technology to improve quality of care for healthy populations and targeted groups of at-risk persons has led to population health management. This paper discusses strategies used in these endeavors. (+info)Rising tide of cardiovascular disease in American Indians. The Strong Heart Study. (6/706)
BACKGROUND: Although cardiovascular disease (CVD) used to be rare among American Indians, Indian Health Service data suggest that CVD mortality rates vary greatly among American Indian communities and appear to be increasing. The Strong Heart Study was initiated to investigate CVD and its risk factors in American Indians in 13 communities in Arizona, Oklahoma, and South/North Dakota. METHODS AND RESULTS: A total of 4549 participants (1846 men and 2703 women 45 to 74 years old) who were seen at the baseline (1989 to 1991) examination were subjected to surveillance (average 4.2 years, 1991 to 1995), and 88% of those remaining alive underwent a second examination (1993 to 1995). The medical records of all participants were exhaustively reviewed to ascertain nonfatal cardiovascular events that occurred since the baseline examination or to definitively determine cause of death. CVD morbidity and mortality rates were higher in men than in women and were similar in the 3 geographic areas. Coronary heart disease (CHD) incidence rates among American Indian men and women were almost 2-fold higher than those in the Atherosclerosis Risk in Communities Study. Significant independent predictors of CVD in women were diabetes, age, obesity (inverse), LDL cholesterol, albuminuria, triglycerides, and hypertension. In men, diabetes, age, LDL cholesterol, albuminuria, and hypertension were independent predictors of CVD. CONCLUSIONS: At present, CHD rates in American Indians exceed rates in other US populations and may more often be fatal. Unlike other ethnic groups, American Indians appear to have an increasing incidence of CHD, possibly related to the high prevalence of diabetes. In the general US population, the rising prevalence of obesity and diabetes may reverse the decline in CVD death rates. Therefore, aggressive programs to control diabetes and its risk factors are needed. (+info)Long-term trend toward earlier breeding in an American bird: a response to global warming? (7/706)
In regions with severe winters, global warming may be expected to cause earlier onset of breeding in most animals, yet no documentation of such a trend exists in North America. In a study of marked individuals of the Mexican jay (Aphelocoma ultramarina) in southeastern Arizona, from 1971 to 1998, the mean Julian date of first clutch in the population declined significantly by 10.1 days. The date of the first nest in the population also became earlier, by 10.8 days. These changes were associated with significant trends toward increased monthly minimum temperatures on the study area, traits that are associated with the onset of breeding in this population. Significant trends from 1971 to 1997 toward warmer minimum temperatures in the months before and during the initiation of breeding were observed. These trends parallel changes in minimum temperatures and community composition in a recent study of grassland ecology in the western United States. Together, they suggest that more attention should be given to the possible ecological importance of global change in minimum temperatures. (+info)Amputation prevention by vascular surgery and podiatry collaboration in high-risk diabetic and nondiabetic patients. The Operation Desert Foot experience. (8/706)
OBJECTIVE: To describe a unique multidisciplinary outpatient intervention for patients at high risk for lower-extremity amputation. RESEARCH DESIGN AND METHODS: Patients with foot ulcers and considered to be high risk for lower-extremity amputation were referred to the High Risk Foot Clinic of Operation Desert Foot at the Carl T. Hayden Veterans Affairs' Medical Center in Phoenix, Arizona, where patients received simultaneous vascular surgery and podiatric triage and treatment. Some 124 patients, consisting of 90 diabetic patients and 34 nondiabetic patients, were initially seen between 1 October 1991 and 30 September 1992 and followed for subsequent rate of lower-extremity amputation. RESULTS: In a mean follow-up period of 55 months (range 3-77), only 18 of 124 patients (15%) required amputation at the level of the thigh or leg. Of the 18 amputees, 17 (94%) had type 2 diabetes. The rate of avoiding limb loss was 86.5% after 3 years and 83% after 5 years or more. Furthermore, of the 15 amputees surviving longer than 2 months, only one (7%) had to undergo amputation of the contralateral limb over the following 12-65 months (mean 35 months). Compared with nondiabetic patients, patients with diabetes had a 7.68 odds ratio for amputation (95% CI 5.63-9.74) (P < 0.01). CONCLUSIONS: A specialized clinic for prevention of lower-extremity amputation is described. Initial and contralateral amputation rates appear to be far lower in this population than in previously published reports for similar populations. Relative to patients without diabetes, patients with diabetes were more than seven times as likely to have a lower-extremity amputation. These data suggest that aggressive collaboration of vascular surgery and podiatry can be effective in preventing lower-extremity amputation in the high-risk population.

"Salmonella arizonae" is a gram-negative, rod-shaped bacterium that is motile and facultatively anaerobic. It is a species within the genus Salmonella, which are commonly associated with foodborne illnesses in humans and animals. However, "Salmonella arizonae" is primarily associated with reptiles and is rarely known to cause disease in humans. It can be found in the intestinal tracts of reptiles, amphibians, and birds, and can contaminate their environments, including water and soil. In rare cases, human infection may occur through direct contact with infected animals or their feces, consumption of contaminated food or water, or person-to-person transmission. The clinical presentation of "Salmonella arizonae" infection in humans is similar to other Salmonella infections, typically causing gastroenteritis characterized by diarrhea, abdominal cramps, and fever.
Coccidioidomycosis is a fungal infection caused by the inhalation of spores of the Coccidioides species, mainly C. immitis and C. posadasii. These fungi are commonly found in the soil of dry regions such as the southwestern United States, Mexico, and Central and South America.
The infection often begins when a person inhales the microscopic spores, which can lead to respiratory symptoms resembling a common cold or pneumonia. Some people may develop more severe symptoms, especially those with weakened immune systems. The infection can disseminate to other parts of the body, causing skin lesions, bone and joint inflammation, meningitis, or other complications in rare cases.
Diagnosis typically involves a combination of clinical evaluation, imaging studies, and laboratory tests such as fungal cultures, histopathological examination, or serological tests to detect antibodies against Coccidioides antigens. Treatment depends on the severity of the infection and the patient's immune status. Antifungal medications like fluconazole, itraconazole, or amphotericin B are commonly used for treating coccidioidomycosis. Preventive measures include avoiding inhaling dust in endemic areas, especially during excavation or construction activities.
"Native Americans" is the preferred term for the indigenous peoples of the continental United States, including those from Alaska and Hawaii. The term "Indians" is often used to refer to this group, but it can be seen as misleading or inaccurate since it implies a connection to India rather than recognition of their unique cultures and histories. However, some Native Americans prefer to use the term "Indian" to describe themselves.
It's important to note that there is no single medical definition for this group, as they are not a homogeneous population. Instead, they consist of hundreds of distinct tribes with diverse cultures, languages, and traditions. Each tribe may have its own unique genetic makeup, which can influence health outcomes and responses to medical treatments.
Therefore, when discussing medical issues related to Native Americans, it's essential to consider the specific tribal affiliations and cultural factors that may impact their health status and healthcare needs.
I'm sorry for any confusion, but "South Dakota" is not a medical term or concept. It is a geographical location, being one of the 50 states in the United States of America. If you have any questions related to medical topics, I would be happy to try and help answer those for you!
"Escherichia" is a genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that are commonly found in the intestines of warm-blooded organisms. The most well-known species in this genus is "Escherichia coli," or "E. coli," which is a normal inhabitant of the human gut and is often used as an indicator of fecal contamination in water and food. Some strains of E. coli can cause illness, however, including diarrhea, urinary tract infections, and meningitis. Other species in the genus "Escherichia" are less well-known and are not typically associated with disease.
I'm sorry for any confusion, but "North Dakota" is a state in the United States and not a medical term or condition. The term refers to the 39th state admitted to the union on November 2, 1889. It is located in the Upper Midwest region of the United States and is known for its expansive prairies, badlands, and oil reserves. If you have any questions related to medical definitions or health-related topics, I would be happy to help answer them!
Salmonella is a genus of rod-shaped, Gram-negative bacteria that are facultative anaerobes and are motile due to peritrichous flagella. They are non-spore forming and often have a single polar flagellum when grown in certain conditions. Salmonella species are important pathogens in humans and other animals, causing foodborne illnesses known as salmonellosis.
Salmonella can be found in the intestinal tracts of humans, birds, reptiles, and mammals. They can contaminate various foods, including meat, poultry, eggs, dairy products, and fresh produce. The bacteria can survive and multiply in a wide range of temperatures and environments, making them challenging to control completely.
Salmonella infection typically leads to gastroenteritis, characterized by symptoms such as diarrhea, abdominal cramps, fever, and vomiting. In some cases, the infection may spread beyond the intestines, leading to more severe complications like bacteremia (bacterial infection of the blood) or focal infections in various organs.
There are two main species of Salmonella: S. enterica and S. bongori. S. enterica is further divided into six subspecies and numerous serovars, with over 2,500 distinct serotypes identified to date. Some well-known Salmonella serovars include S. Typhi (causes typhoid fever), S. Paratyphi A, B, and C (cause paratyphoid fever), and S. Enteritidis and S. Typhimurium (common causes of foodborne salmonellosis).
Entomophthorales is a order of fungi that are known for their ability to infect and kill insects and other small arthropods. The name "Entomophthorales" comes from the Greek words "entomon," meaning insect, and "phthora," meaning destruction.
The fungi in this order typically infect their hosts by producing structures called appressoria, which help the fungus penetrate the host's cuticle. Once inside the host, the fungus grows and multiplies, eventually killing the host and releasing spores that can infect other insects or arthropods.
Entomophthorales includes several families of fungi, including Entomophthoraceae, Ancylistaceae, and Completoriaceae. Some species in this order are being studied for their potential as biological control agents for pest insects. However, it is important to note that some species in this order can also infect humans, although such infections are rare and usually only occur in people with weakened immune systems.

"Rhipicephalus sanguineus" is the medical term for the brown dog tick. It is a species of tick that is widely distributed around the world and is known to feed on a variety of hosts, including dogs, cats, and humans. The brown dog tick is a vector for several diseases, including canine babesiosis and Rocky Mountain spotted fever. It can survive and reproduce in indoor environments, making it a common pest in homes and kennels. The tick undergoes a four-stage life cycle: egg, larva, nymph, and adult. Each stage requires a blood meal before molting to the next stage or reproducing.
