Intervention trial with calcium montmorillonite clay in a south Texas population exposed to aflatoxin.

South Texas currently has the highest incidence of hepatocellular carcinoma (HCC) in the United States, a disease that disproportionately affects Latino populations in the region. Aflatoxin B1 (AFB1) is a potent liver carcinogen that has been shown to be present in a variety of foods in the United States, including corn and corn products. Importantly, it is a dietary risk factor contributing to a higher incidence of HCC in populations frequently consuming AFB1-contaminated diets.

Difficult encounters with psychiatric patients: a South Texas Psychiatry practice-based research network (PBRN) study.

Purpose: To examine the prevalence of difficult psychiatrist-patient interactions of 20 psychiatrists in the South Texas Psychiatric practice-based research network, determine what characteristics were associated with "difficult" patients, and compare findings with previous studies in primary care.

Methods: During a 2-month observational study, psychiatrists collected patient information on setting, demographics, diagnoses, and medications and rated the patients using the Difficult Doctor-Patient Relationship Questionnaire, which had previously been used and validated in the primary care setting.

Results: A total of 905 valid data cards were collected.
