Diet and chronic atrophic gastritis: a case-control study 总被引:2,自引:0,他引:2

A hospital-based case-control study of gastric cancer precursor lesions was conducted in a high-risk black population in southern Louisiana. Ninety-three subjects with biopsy-proved advanced chronic atrophic gastritis were compared to two control series: a gastroscopy clinic series and a general hospital-admission series. Dietary case-control differences indicated a protective effect associated with fruit and vegetable intake and with dietary vitamin C and a risk elevation associated with milk consumption. The protective effect associated with consumption of fruits, vegetables, and vitamin C is consistent with findings for gastric cancer and with the etiologic hypothesis of intragastric nitrosation. A twofold increased risk was associated with cigarette smoking. Gastric juice pH, NO3-, and NO2- were determined for subjects undergoing gastroscopy, and comparisons were made between this high-risk U.S. group and a Colombian population with a much greater magnitude of risk; the latter had higher NO3- and NO2- levels. An increase in pH was associated with increasing severity of gastric lesions. Levels of pH and NO2- concentration were significantly correlated (P less than .0005); however, in Louisiana the large difference in NO2- concentration associated with pH elevation is not associated with histopathologic severity. Divergent trends with severity of lesions for NO3- concentration were seen in the two populations. 相似文献

To conduct a formative and pilot impact evaluation of the State Technical Assessment Team (STAT) program, a visitation-based (visitatie) peer assessment program designed to enhance the organizational capacity of state health department injury prevention programs. The formative evaluation was based on observational, record review, and key informant interview data collected during the implementation of the first 7 STAT visits. Pilot impact data were derived from semi-structured interviews with state injury prevention personnel one year after the visit. Formative evaluation identified 6 significant implementation problems in the first visits that were addressed by the program planners, resulting in improvements to the STAT assessment protocol. Impact evaluation revealed that after one year, the 7 state injury prevention programs had acted on 81% of the recommendations received during their STAT visits. All programs reported gains in visibility and credibility within the state health department and increased collaboration and cooperation with other units and agencies. Other significant program advancements were also reported. Specific program standards and review procedures are important to the success of peer assessment programs such as STAT. Early impact evaluation suggests that peer assessment protocols using the visitatie model can lead to gains in organizational capacity. 相似文献

Twenty adolescent male sexual offenders were evaluated by penile plethysmography on two separate occasions. Stimuli consisted of 19, two-minute audiotaped cues. Test-retest reliability was demonstrated for 15 of the 19 audiotaped vignettes. The highest correlations were found for those sexual behaviors in which the adolescents had engaged. 相似文献

Manipulation of gamma-aminobutyrate (GABA) system has been little studied in Parkinson's disease, despite the fact that GABA subserves a large part of the basal ganglia, including the outflow tracts. To test whether antagonism of GABA could improve features of PD, we administered open label intravenous flumazenil to eight practically defined off patients and assessed UPDRS scores, bilateral 1-minute hand-tapping speed, and timed gait tests. Patients demonstrated significantly greater tapping speed, which peaked 40 minutes after injection (P < 0.05). Total motor Unified Parkinson's Disease Rating Scale scores modestly improved (P < 0.05). There were no adverse events. Mechanisms by which flumazenil could improve PD are discussed. 相似文献

We have recently treated a patient with an arteriovenous fistula that developed after a right internal jugular vein catheterization. The patient was found to have a pulsatile hematoma and a bruit five days after removal of a temporary pacemaker catheter. Digital subtraction arteriography documented a fistula between the right internal mammary artery and subclavian vein. The fistula was surgically repaired via the cervical route. To our knowledge, an arteriovenous fistula between the internal mammary artery and subclavian vein has not been previously described as a complication of a percutaneous internal jugular vein catheterization. 相似文献

ABSTRACT: This study obtained input from Australian student smokers approximately 15 years old, which may be useful in designing school-based smoking cessation programs. The sample was analyzed by previous quitting experience and intentions to quit. The order of preference for assistance options and incentives for quitting was similar across all groups: however, those who previously attempted to quit (previous quitters) and those who intended to quit (intenders) in the future were significantly more likely than non-quitters and non-intenders to find assistance options for quitting acceptable. The potential for saving money emerged as an important variable in convincing all groups of smokers not to smoke, and using personal willpower and cutting down slowly were identified as important in actual attempts to quit. The need for programs to be free and for friends to be supportive also was evident across all groups. 相似文献
