A longitudinal investigation of marital dissolution, marital quality, and generalized anxiety disorder in a national probability sample.

Generalized anxiety disorder (GAD) is a common psychiatric disorder that is associated with high levels of distress and impairment. The present study was conducted to examine the 10-year longitudinal associations between marital dissolution, three measures of marital quality, and GAD among married participants from the Midlife in the United States (MIDUS) survey, a probability sample of American adults aged 24-74 years. Results indicated that GAD at baseline was significantly and positively associated with incidence of marital dissolution during the 10-year follow-up and marital strain (i.

Reliable information for cancer control in Cali, Colombia.

Background: The Cali Population Cancer Registry (RPCC) has been in continuous operation since 1962 with the objective of producing valid statistics on the incidence of cancer, its patterns, trends and survival rates.

Methods: During the period 2008-2012, 23,046 new cases were registered and during 2011-2015 there were 12,761 cancer deaths. The trend of the rates was described with the APC average annual change rate and with the Joinpoint analysis.

Trends of cancer incidence and mortality in Cali, Colombia. 50 years experience.

Purpose: The Population-based Cancer Registry of Cali aims to report all new cases in permanent residents within the limits of the city of Cali. Time trends of cancer incidence and mortality are described. The registry has been in continuous operation for 50 years.

A randomized clinical trial to determine the efficacy of regimens containing clarithromycin, metronidazole, and amoxicillin among histologic subgroups for Helicobacter pylori eradication in a developing country.

Background: Most treatments deemed effective for Helicobacter pylori eradication in developed countries are less effective in developing countries. Regimens containing clarithromycin, metronidazole, and amoxicillin seem efficacious despite antibiotic resistance, and may be a viable option in developing countries.

Materials And Methods: We evaluated the efficacy of a 14-day regimen with 500 mg clarithromycin b.

Anti-inflammatory and tissue-protectant drug effects: results from a randomized placebo-controlled trial of gastritis patients at high risk for gastric cancer.

Background: The inflammatory process involving Helicobacter pylori-associated gastritis is thought to lead to epithelial damage and contribute to the development of gastric cancer. Evidence exists from animal and in vitro studies suggesting that tetracyclines have both anti-inflammatory and tissue-protectant effects unrelated to their antimicrobial activity. We attempted to modulate components of H.

Nutritional factors and Helicobacter pylori infection in Colombian children.

Background: Helicobacter pylori infection occurs most frequently in impoverished populations; however, little is known about specific determinants of susceptibility. This report describes the relationship between H. pylori infection and nutritional indicators among children from a rural village in the Colombian Andes, where a prevalence of 69% was observed in children from 2 to 9 years old.

Gastric precancerous process in a high risk population: cohort follow-up.

In an attempt to characterize the natural history of the gastric precancerous process, 1422 residents of a high risk area of Nariño, Columbia, have been followed from 3-16 years (average 5.1) with repeated gastric biopsies, for a total of 7290 person-years. The original cohort consisted of 1788 individuals yielding a successful completion rate of 79.

Gastric precancerous process in a high risk population: cross-sectional studies.

The gastric precancerous process is evaluated in 1788 participants in a gastroscopy survey in the population of Nariño, Colombia, which has one of the highest gastric cancer incidence rates on record. A detailed histological classification is used, and a hierarchical distribution of lesions is described with the main stages being gland neck hyperplasia, atrophy (gland loss), intestinal metaplasia and dysplasia. Acute inflammation was not found to be a specific stage in the sequence but rather a common finding in all stages of the precancerous spectrum.

Genetic etiology of gastric carcinoma: I. Chronic atrophic gastritis.

Scientific evidence has accumulated to show that chronic atrophic gastritis (CAG) is a precursor of gastric carcinoma, especially its intestinal histologic type; thus the etiology of CAG is of interest. Data on 110 families (557 individuals) collected as part of a large cohort from the Narino region of Colombia, South America, are analyzed to determine the familiality of CAG as a risk factor, and the possible involvement of a major gene in its etiology. We found that age and having an affected mother are important risk factors.

The impact of vaginal cytology on cervical cancer risks in Cali, Colombia.

The role of vaginal cytology screening in preventing invasive carcinoma of the cervix was investigated in Cali, Colombia. The history of previous participation in screening programs was obtained from 204 patients with invasive carcinoma and from 2 sets of age-matched controls: one from the same health center and one for the same neighborhood of the patient. Our results show that the risk of developing invasive carcinoma is at least 10 times greater in non-screened than in screened women.
