AIMS--To use a range of natural phenotypically variant strains Helicobacter pylori with disparate CagA and VacA (vacuolating cytotoxin) expression to determine which bacterial factors are more closely associated epithelial interleukin-8 (IL-8) induction. METHODS--Gastric cells (AGS KATO-3) were co-cultured five H variously shown express the cagA gene/CagA protein, and/or exhibit biological cytotoxicity. Secreted IL-8 was assayed by enzyme leaked immunosorbent assay (ELISA) messenger RNA...

To identify the diagnostic characteristics and counseling needs of individuals at risk for acquired immune deficiency syndrome (AIDS), standardized DSM-III-R diagnoses were given to 207 physically asymptomatic adults when they sought serological testing human immunodeficiency virus (HIV). The subjects had high lifetime rates mood disorders. Even after 20 with intravenous drug use as a factor eliminated, nonalcohol substance dependence also high. These findings suggest that even before are...

We examined adherence to highly active antiretroviral therapy (HAART) in the homeless population, a population thought be at high risk for poor and development of drug-resistant strains human immunodeficiency virus (HIV).We performed 12-month prospective study 148 persons receiving HAART who were identified stratified screening marginally housed. sampled lunch lines, shelters, hotels 3 neighborhoods San Francisco, California. used pill counts unannounced home visits as primary measure...

OBJECTIVE: Opinions differ about the effects of Holocaust on adult offspring survivors. The authors studied cancer patients who were second-generation survivors in an attempt to determine whether they react their illness with high distress found be a characteristic survivors.METHOD: In study population women breast cancer, 106 compared 102 whose parents not Holocaust. Background information was obtained by interviews. addition, all completed three self-reports: Mental Attitude Cancer Scale,...

With continuing emigration from endemic countries, screening for parasitic infections remains a priority in U.S. communities serving refugee and immigrant populations. We report the prevalence of helminths protozoa as well demographic risk factors associated with these among 533 refugees seen at Santa Clara County, California, Refugee Clinic between October 2001 January 2004. Stool parasites were identified 14% refugees, including 9% found to have one or more 6% least helminth. Most common...

Helicobacter pylori is transmitted within households and high concordance observed among siblings. To better understand the contributions of close interpersonal contact family relatedness to transmission, we compared H. infection 241 sibling non-sibling children aged 2–18 years in 68, predominantly low-income, Hispanic with at least two nuclear families. Prevalence was 24%. Compared no infected siblings or non-siblings adjusting for age, odds were 1·2 (95% CI 0·52–2·9), 3·2 1·14–9·1), 9·4...

SUMMARY We screened 176 healthy, adult (aged 18–55 years) US refugees from tuberculosis (TB)-endemic countries to evaluate whether cytokine responses latent TB infection (LTBI) are modified in the setting of concurrent H. pylori and helminth infection. As measured by Quantiferon-TB GOLD interferon-γ release assay, a total 38 (22%) subjects had LTBI, which 28 (74%) also were seropositive and/or infected. Relative ten with LTBI only, 16 significantly elevated levels IFN-γ, nine both IL-2,...

To investigate the association of cagA positivity and non-opsonic neutrophil activation capacity in wild-type Helicobacter pylori strains with peptic ulcer disease or chronic gastritis only.Helicobacter were isolated from antral biopsies 53 consecutive patients gastritis, whom 24 had endoscopically. The presence cagA, a marker for cag pathogenicity island, was determined by polymerase chain reaction specific oligonucleotide primers, luminol enhanced chemiluminescence.The gene present 39...

To determine the prevalence of alcoholism among patients at a large inpatient burn center, semistructured interview for diagnosing alcoholism—the CAGE questionnaire—was administered. Of 124 interviewed, 24 (19 percent) were found to have an alcohol problem based on responses questionnaire. However, when patients' charts reviewed discharge, only seven subjects described as having alcohol-related problem. 22 whose was detected by questionnaire and whom blood alcobol screens had been obtained...

La diabetes mellitus tipo 2 (DMT2) representa un problema de salud pública en México por los altos índices morbilidad y mortalidad debido a la falta adherencia al tratamiento farmacológico. El objetivo fue analizar farmacológico mediante modelo ecuaciones estructurales. A través estudio cuantitativo, no experimental, descriptivo, transversal correlacional-explicativo, se trabajó con una muestra conveniencia 261 personas DMT2 (64% mujeres 36% hombres), media 52.93 años diagnóstico Chetumal,...
