Colorectal cancer incidence and mortality disparities in new Mexico.

Background. Previous analyses indicated that New Mexican Hispanics and American Indians (AI) did not experience the declining colorectal cancer (CRC) incidence and mortality rates observed among non-Hispanic whites (NHW). We evaluated more recent data to determine whether racial/ethnic differences persisted. Methods. We used New Mexico Surveillance Epidemiology and End Results data from 1995 to 2009 to calculate age-specific incidence rates and age-adjusted incidence rates overall and by tumor stage. We calculated mortality rates using National Center for Health Statistics' data. We used joinpoint regression to determine annual percentage change (APC) in age-adjusted incidence rates. Analyses were stratified by race/ethnicity and gender. Results. Incidence rates continued declining in NHW (APC -1.45% men, -1.06% women), while nonsignificantly increasing for AI (1.67% men, 1.26% women) and Hispanic women (0.24%). The APC initially increased in Hispanic men through 2001 (3.33%, P = 0.06), before declining (-3.10%, P = 0.003). Incidence rates declined in NHW and Hispanics aged 75 and older. Incidence rates for distant-stage cancer remained stable for all groups. Mortality rates declined significantly in NHW and Hispanics. Conclusions. Racial/ethnic disparities in CRC persist in New Mexico. Incidence differences could be related to risk factors or access to screening; mortality differences could be due to patterns of care for screening or treatment.

Surveillance of colorectal cancer screening in new Mexico hispanics and non-Hispanic whites.

The incidence of colorectal cancer (CRC) among Hispanics in the state of New Mexico has increased in the past decade while that among whites has declined significantly. Using the 2006 New Mexico Behavioral Risk Factor Surveillance System (BRFSS) survey, we compared CRC screening among Hispanics and whites by gender to examine the influence of demographic, socioeconomic, preventive health, and clinical measures on the utilization of CRC screening. Although we found no ethnic differences in the prevalence of current breast, cervical and cancer screening, Hispanics were less likely to be current with CRC screening than whites. These differences were observed across a range of socioeconomic and other explanatory measures and in both genders. Hispanics also had a higher prevalence of CRC-related risk factors than whites, including inactivity, obesity, and diabetes, and ranked lower for most socioeconomic measures. Adjusting for healthcare coverage, education, and income in logistic regression models eliminated the Hispanic-white differences in CRC screening among men, and substantially reduced but did not eliminate screening differences among women. Innovative methods are needed to reach Hispanics to raise awareness of and participation in CRC screening. Because many CRC risk factors are potentially modifiable, appropriate cultural and linguistic interventions tailored to specific Hispanic subgroups and aimed at promoting CRC screening and reducing CRC risk factors may decrease ethnic disparities in CRC incidence.

Barriers to colorectal cancer screening: physician and general population perspectives, New Mexico, 2006.

INTRODUCTION: Colorectal cancer (CRC) screening rates are low in New Mexico. We used statewide surveys of primary care physicians and the general population to characterize CRC screening practices and compare perceptions about screening barriers. METHODS: In 2006, we surveyed 714 primary care physicians in New Mexico about their CRC screening practices, beliefs, and perceptions of patient, provider, and system barriers. A 2004 state-specific CRC screening module for the Behavioral Risk Factor Surveillance System (BRFSS) survey asked 3,355 participants aged 50 years or older why they had not ever or had not recently completed a fecal occult blood test (FOBT) or lower endoscopy. RESULTS: The 216 physicians (30% response rate) reported offering screening to a median 80% of their average-risk patients in the past year and estimated that a median 50% were current with screening. They attributed low screening proportions mainly to patient factors (embarrassment, fear of pain, lack of insurance). However, just 51% of physician respondents used health maintenance flow sheets, and only 13% used electronic medical records to identify patients due for CRC screening. The BRFSS respondents most often reported that lack of physician discussion was responsible for not being current with screening (45% FOBT, 34% endoscopy); being asymptomatic was also often cited as an explanation for lack of screening (22% FOBT, 36% endoscopy). CONCLUSION: Physicians and adults in the general population had markedly different perspectives on barriers to CRC screening. Increasing screening may require system supports to help physicians readily identify patients due for CRC testing and interventions to educate patients about the rationale for screening.

New Mexico's capacity for increasing the prevalence of colorectal cancer screening with screening colonoscopies.

INTRODUCTION: Colorectal cancer screening rates are low throughout the United States. Colonoscopy has been recommended as a cost-effective strategy for colorectal cancer screening and prevention. We evaluated New Mexico's capacity to increase the prevalence of colorectal cancer screening using colonoscopy. METHODS: We identified New Mexican gastroenterologists from state licensing data and from endoscopic manufacturers. We surveyed gastroenterologists on their weekly number of colonoscopies, capacity for additional screening colonoscopies, and barriers to increasing capacity. We used census data, published data on the yield of screening colonoscopy, and professional society guidelines for cancer/polyp surveillance to estimate the additional colonoscopies required to increase the state's prevalence of endoscopic screening. RESULTS: Forty gastroenterologists, representing all 11 group practices in the state, and nine of 12 solo practitioners responded. They estimated that their weekly procedure capacity could be increased by 41%, from 832 to 1174 colonoscopies. We estimated an annual capacity increase of 14,880 procedures, which could increase the prevalence of endoscopic colorectal cancer screening from the current 35% to about 50% over five years. Lack of support staff, space, and physicians were barriers to increasing screening. CONCLUSION: Implementing a screening colonoscopy strategy could achieve the goal of a higher level of colorectal screening. However, achieving more universal screening would require additional testing modalities.

Antibiotic prescribing for patients with colds, upper respiratory tract infections, and bronchitis: A national study of hospital-based emergency departments.

STUDY OBJECTIVE: Antibiotics are often used to treat viral upper respiratory tract infections, even though they are usually ineffective. However, frequent inappropriate antibiotic use contributes to the emergence of drug-resistant bacterial pathogens. This study used a national database to evaluate antibiotic use in treating upper respiratory tract infections in emergency departments. METHODS: Data were obtained from the 1996 National Hospital Ambulatory Medical Care Survey. Antibiotic prescribing rates were examined for colds, upper respiratory tract infections, and acute bronchitis. Patients with comorbid conditions or secondary diagnoses, such as chronic obstructive pulmonary disease, pneumonia, sinusitis, and HIV, were excluded. Bivariate and multivariate analyses were used to assess predictors of antibiotic use. RESULTS: Overall, there were an estimated 2.7 million ED visits for colds, upper respiratory tract infections, and bronchitis by children and adults in 1996. Antibiotics were prescribed for 24.2% (95% CI 18.9, 29.5) of patients with common colds and upper respiratory tract infections and for 42.2% (95% CI 35.2, 49.2) of patients with bronchitis. There were no significant associations between antibiotic use and patient race, sex, Hispanic ethnicity, geographic location, or source of payment. Antibiotics were prescribed less often by interns or residents than by staff or other physicians (odds ratio 0.43; 95% CI 0.19, 0.98), and patients younger than 18 years were less likely to receive antibiotics than adults (odds ratio 0.32; 95% CI 0.20, 0.52). Smokers were 4.3 (95% CI 2.2, 8.3) times more likely to receive antibiotics than nonsmokers. CONCLUSION: Antibiotics are commonly prescribed for ED patients with upper respiratory tract infections even though they are usually ineffective in otherwise healthy adults. Efforts should be made to reduce inappropriate antibiotic use for the sake of containing costs, preventing side effects, and limiting the spread of antibiotic resistance.

[Correlation between plasma progesterone and ultrasonographic detection of corpus luteum in ovulatory cycles]. / Correlacion entre progesterona plasmatica y deteccion ultrasonografica de cuerpo luteo en ciclos ovulatorios.

The ultrasound detection of corpus luteum in the midluteal phase of ovulatory cycles was associated with significantly higher levels of plasma progesterone, opposed to those patients where a corpus luteum could not be identified. The hormone level was directly proportional no the number of corpora lutea seen. However, only 33.3% o patients with no corpus luteum visible were found to have suboptimal plasma progesterone levels (< 10 ng/ml).

Radiologic evaluation of incremental intrauterine instillation of contrast material.

In view of the contradictory results of IUI reported in the literature, the present study was undertaken to determine whether the volume of material injected into the uterus can affect the delivery site of the sperm. Ten infertile women scheduled for HSG were submitted to intrauterine injection of different volumes of radiopaque dye (0.2 mL to 1.0 mL) before the procedure to mimic IUI. An x ray taken immediately after injection showed that volumes of > or = 0.4 mL reached the uterus and tubes, whereas the 0.2-mL volume did not reach the tube. These data show that volume injected is an important variable in IUI.

Comparaçäo entre o teste do hamster e a análise espermática comun numa populaçäo masculina infértil / Comparison betweem the hamster test and commom sperm analysis in the infertile male population

Acredita-se que o teste do hamster (TH) possui uma alta sensibilidade e especificidade, na seleçäo da populaçäo masculina infértil. Uma análise crítica foi executada entre o TH e os parâmetros da análise espermática comum (AEC), com respeito a sensibilidade, especificidade e valores preditivos normais e anormais, durante o seguimento de uma populaçäo infértil. O estudo prospectivo inclui 142 casais inférteis, com duraçäo média da infertilidade entre 5 + 2, 48 ano, e idade dos homens entre 28 e 46 anos. A propedêutica de investigaçäo do fator feminino foi completa, sendo todas as anormalidades presentes corrigidas, antes da inclusäo das pacientes no estudo. Em todos os casos, a permeabilidade tubária foi no mínimo unilateral, e os casais foram acompanhados pelo período de um ano. O TH foi executado segundo Rogers (1979), tendo como principais modificaçöes o emprego do tempo de incubaçäo curto (3-4 horas) e do meio de cultura Ham-F10. O TH mostrou uma baixa sensibilidade (25,8%) semelhante `a aquela da AEC (concentraçäo = 14,5%, motilidade = 15,3% e morfologia = 32,2%). A especificidade do TH foi de 88,8%; todavia, näo diferiu daquela da AEC (concentraçäo = 94,4%, motilidade = 83,3%). O valor preditivo de gravidez com o TH normal foi de 14,8%, comparável com os obtidos com a AEC (concentraçäo = 13,8%, motilidade = 12,5%, morfologia = 15,1%). O valor preditivo da ausência de gravidez através do TH anormal foi de 94,1%; contudo esses altos índices de acerto podem também ser obtidos com a AEC (concentraçäo = 94,7%, motilidade = 86,3%, morfologia = 93%). Dessa forma, pode-se sugerir que, no caso de valores anormais de TH e AEC, o prognóstico de futura gravidez é baixo. Por outro lado, a AEC ainda é o método inicial na avaliaçäo do homem infértil, reservando-se o TH para os casos em que, apesar de AEC estar persistentemente normal, ainda näo surgiu a gravidez
