Are primary-care physician practices related to health behaviors likely to reduce social inequalities in health?

2017

Abstract Our objective was to examine patients' health behaviors and the related practices of their primary-care physicians to determine whether physicians' actions might help to reduce the social inequalities in health behaviors among their patients. Fifty-two general practitioners, who were also medical school instructors in the Parisian area, volunteered to participate. A sample of 70 patients (stratified by sex) aged 40–70 years was randomly chosen from each physician's patient panel and asked to complete a questionnaire about their social position and health behaviors: tobacco and alcohol use, diet, physical activity, and participation in breast and cervical cancer screening. Each phys…

Comparing the results of a cholesterol and saturated fat screener when using two different scores.

2003

Screener are useful instruments for categorising individuals according to their nutrient intake. To accurately classify the individuals it is important to correctly analyse the screener. Therefore we compared a simple and a weighed score of a cholesterol and saturated fat (SF) screener with the cholesterol and SF intake, respectively, calculated from an extensive food frequency questionnaire. The validation results did not change when a weighed score was used instead of the simple one, indicating that a simple score does not introduce a higher amount of misclassification.

Screening for generalized anxiety disorder in Spanish primary care centers with the GAD-7.

2017

The aim of the study was to determine the criterion validity of a computerized version of the General Anxiety Disorder-7 (GAD-7) questionnaire to detect general anxiety disorder in Spanish primary care centers. A total of 178 patients completed the GAD-7 and were administered the Composite International Diagnostic Interview (CIDI) for DSM-IV Axis I Disorders, which was used as a reference standard. Sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were calculated. A cut-off of 10 yielded a sensitivity of .87, a specificity of .78, a positive predictive value of .93, a negative predictive value of .64, a positive likelihood ratio o…

Usefulness of routine hepatitis C and hepatitis B serology in the diagnosis of recent-onset arthritis. Systematic prospective screening in all patien…

Ansemant, Thiphaine | Ornetti, Paul | Garrot, Jean-Francois | Pascaud, Francoise | Tavernier, Christian | Maillefert, Jean-Francis; International audience; ''Objective: Previous studies evaluating the usefulness of systematic screening for hepatitis B and C in patients with recent-onset arthritis suffered from a major bias since they were conducted in hospitals. The objective of the present study was to evaluate the relevance of such screening, performed by hospital and office-based rheumatologists of a defined area, in the diagnosis of arthritis or inflammatory polyarthralgia of less than 1 year duration. Methods: The CRRRI is a network which includes most hospital and office-based rheumat…

The symptom check-list, SCL-90-R: its use and characteristics in chronic pain patients

2000

The SCL-90-R is a widely-used questionnaire for self-report of psychological distress and multiple aspects of psychopathology, as part of the evaluation of chronic pain patients and other non-psychiatric populations. The aim of this study is the presentation of clinical results of this multidimensional questionnaire in a convenience sample of 3540 chronic pain patients treated in a multidisciplinary pain centre. Confirmatory Factor Analysis (CFA), Exploratory Factor Analysis (EFA), single scale factor analyses and Cronbach's alphas are used to assess the internal structure and correlation to other instruments (CES-D, STAI, MPSS) to assess construct validity. It is shown that the 9 dimension…

Risk of Non-Hodgkin Lymphoma in Celiac Disease

2002

CONTEXT: Celiac disease is one of the most common lifelong disorders. Non-Hodgkin lymphoma is a possible complication of celiac disease and may lead to a large portion of lymphoma cases. OBJECTIVE: To quantify the risk for developing non-Hodgkin lymphoma of any primary site associated with celiac disease. DESIGN AND SETTING: Multicenter, case-control study conducted between January 1996 and December 1999 throughout Italy. PATIENTS: Cases were older than 20 years (median, 57; range, 20-92 years) with non-Hodgkin lymphoma of any primary site and histological type and were recruited at the time of the diagnosis. Controls were healthy adults (2739 men and 2981 women) from the general population…

Improved identification of heterozygotes for phenylketonuria using blood neopterin and biopterin

1993

A novel approach that combines information provided by the metabolism of pteridines and that of phenylalanine has been applied to the detection of heterozygotes for phenylketonuria. Phenylalanine, tyrosine, biopterin and neopterin have been measured in serum from normal controls and heterozygotes for classical phenylketonuria, before and after a phenylalanine oral load. Significant differences in neopterin and biopterin mean values in fasting serum and in the mean increase of biopterin induced by the phenylalanine load were found between groups. Inclusion of pteridine data in the discriminant analysis significantly improved the resolution of the classical phenylalanine loading test for the …

Screening for gastric cancer using exhaled breath samples.

2019

Abstract Background The aim was to derive a breath-based classifier for gastric cancer using a nanomaterial-based sensor array, and to validate it in a large screening population. Methods A new training algorithm for the diagnosis of gastric cancer was derived from previous breath samples from patients with gastric cancer and healthy controls in a clinical setting, and validated in a blinded manner in a screening population. Results The training algorithm was derived using breath samples from 99 patients with gastric cancer and 342 healthy controls, and validated in a population of 726 people. The calculated training set algorithm had 82 per cent sensitivity, 78 per cent specificity and 79 …

Pepsinogen Test for the Evaluation of Precancerous Changes in Gastric Mucosa: a Population-Based Study

2018

Aims: The aim of the study was to evaluate the rationale of blood pepsinogen (PG) testing in population based screening settings.Methods: Participants from a cross-sectional population-based study of cardiovascular risk factors in Latvia were invited to participate in the current study. Pepsinogen I and II were measured in blood samples taken during the initial study and at follow-up; upper gastrointestinal endoscopy was performed. There were three groups of patients: with moderately decreased (PG I< 70 ng/ml and PG I/PG II ratio < 3), with strongly decreased (PG I< 30 ng/ml and PG I/PG II ratio < 2), and with normal PG level. Biopsy with H. pylori detection was performed (updat…
