From initial telephone interviews with a random population of 1187 francophone women, 179 women participated in a further three-hour person-to-person interview focusing on the use of psychotropic medications. Psychotrope users typically were older, in poorer health, and had a lower level of education than abstainers. They showed an increased prevalence of nervousness, anxiety, depression, and restlessness. Initial contact with psychotrope use was through their general practitioners after presentation of vague and ill-defined symptoms. Psychotropic drug use was found among housewives, especially those with children, and among those unemployed but desiring work. Personality profiles of psychotrope users showed that they think of themselves as failures and are more distressed, with significantly greater life changes. Users scored higher on "femininity" subscales, apparently reflecting dependent and nondefensive personality types. In addition, personality measures defined psychotrope users as precise, methodical, cautious, serious, unassertive, and modest. The incompleteness of present unidirectional models of psychotropic drug use are discussed. Suggestions for future research include encompassing the cognitive organization of the psychotrope user within the context of social, affective, and physician influences on this form of coping style. 相似文献

T-antigen expression by peanut agglutinin staining relates to mucosal dysplasia in ulcerative colitis 总被引:2,自引:1,他引:1
Dr. Eric Pihl M.D. Anita Peura B.Sc. Hons. William R. Johnson M.D. Francis T. McDermott M.D. Edward S. R. Hughes M.D. 《Diseases of the colon and rectum》1985,28(1):11-17
Staining of 326 rectal mucosal biopsies from ulcerative colitis patients with peanut agglutinin (PNA), which binds to the T-blood group antigen and has been claimed to reflect a cancer-associated mucin alteration, showed highly significant direct associations with mucosal dysplasia (P less than 0.001), disease activity (P less than 0.001), and subsequent development of rectal cancer in a smaller series of patients (P = 0.005). Staining for normal colonic mucin by the Dolichos biflorus (DBA) lectin related significantly and inversely to dysplasia. Intense normal colon mucin staining by DBA related significantly (P less than 0.025) to long disease duration and to subsequent development of cancer (P = 0.02). The latter association is based on a small number of patients only and is not considered conclusive evidence, but may provide a link with goblet-cell hyperplasia. The authors conclude that although T-antigen expression relates to dysplasia, the findings of "false" positive and negative rates of 22 and 33 percent respectively, make it unlikely that staining of biopsy sections for the T-antigen by peanut agglutinin will contribute materially to routine assessment for dysplasia and cancer risk prediction in patients with ulcerative colitis. 相似文献

The effect of high NaCl concentration in the vehicle on the toxic and antineoplastic activities of cisplatin [cis-dichloro-diammineplatinum(II)] (CDDP) was reinvestigated in mice. The toxicity, as measured by the survival of mice given CDDP iv, was reduced by 50-60% when the NaCl concentration in the vehicle was raised from 0.9 to 4%. In ascitic P388 leukemia the antineoplastic activity of CDDP given ip was not reduced significantly. However, in all other systems studied the antitumor activity was reduced when the CDDP was dissolved in high NaCl solution. The tumor models studied included systemic P388 and L1210 leukemias, Lewis lung carcinoma, and 5 human tumor xenografts. The human tumors were studied by the subrenal capsule assay. In the case of a malignant melanoma and a malignant fibrous histiocytoma, the effect also was demonstrated in the subcutaneous nude mouse model. In one of the malignant melanomas a 50% increase in the CDDP dose did not compensate for the reduced antitumor activity caused by the high NaCl concentration in the vehicle. These results, which stand in contrast to current views, question the experimental basis for the use of high-NaCl vehicles in the "high-dose" CDDP regimens. 相似文献

Alcoholics have previously been found to be more sensitive to painful stimulation than controls, and more sensitive to the pain-reducing effects of alcohol. The present study was designed to examine these effects in men at high familial-genetic risk for alcoholism and controls. Subjects were assigned to one of four alcohol doses [0.135 (active placebo), 0.50, 0.75, or 1.00 ml 95% USP alcohol/kg body weight]. Ratings of the amount of discomfort and pain experienced during an aversive shock procedure were taken immediately post-shock, both while subjects were sober and after they had consumed one of the four alcohol doses. High risk men were found to rate the experience of the shock as more uncomfortable and painful overall than the low risk controls. Pharmacologically significant levels of alcohol were found to reduce or eliminate these group differences, suggesting that alcohol has a normalizing effect on pain and discomfort perceptions in high risk men. Only the higher doses of alcohol were found significantly to dampen subjects' shock rating scores. High risk males' increased sensitivity to pain and discomfort, combined with the negatively reinforcing effects of reducing these perceptions at moderate to high alcohol doses, may play a role in predisposing high risk males for the development of alcoholism. 相似文献

Mononuclear leucocytes were separated by Hypaque--Ficoll from 60 unselected primary colorectal carcinomas, and then fractionated by rosetting with sheep erythrocytes, either alone (E) or coated with antibody and complement (EAC). The E-rosetting cells, putative T lymphocytes, were cytotoxic in vitro to autologous tumour cells in 18 of the 60 cases, whilst the EAC-rosetting cells were unreactive. This intrinsic T-lymphocyte anti-tumour immunoreactivity was significantly associated with the presence of "cuffs" of small dark lymphocytes at the mesocolic or pararectal edge of the primary tumours, but there was no correlation with antitumour cytotoxic lymphocytes in the patient's blood at the time of operation. 相似文献

OBJECTIVE: To establish the relationship between the first-trimester screening markers [pregnancy-associated plasma protein A (PAPP-A), free human chorionic gonadotrophin-beta (beta-hCG), nuchal translucency (NT)], the Down syndrome (DS) risk estimate, and the adverse outcomes such as low birth weight, small for gestational age (SGA) and pre-term delivery. METHODS: A retrospective cohort study including 1,734 non-selected singleton pregnancies consecutively enrolled into the programme of first-trimester combined screening for DS in a 12-month period at a single centre. Data from the Prenatal Patient Registry in ASTRAIA were combined with the Danish National Newborn Screening Registry and Danish Birth Registry. RESULTS: There was a significant relation between low PAPP-A MoM, low beta-hCG MoM, increased risk estimate for DS and low birth weight and SGA. Low PAPP-A MoM and increased NT showed a significant relation to pre-term and spontaneous pre-term delivery. Low PAPP-A MoM showed a significant relation to early pre-term delivery. CONCLUSION: First-trimester screening markers exhibited a significant relation to low birth weight, SGA and to some extent, to pre-term and early pre-term delivery. The screening performance of individual markers was poor. 相似文献

Scand J Caring Sci; 2011; 25; 3–11 Patients’ experiences of physical limitations in daily life activities when suffering from chronic heart failure; a phenomenographic analysis The aim of the study was to describe how patients suffering from chronic heart failure conceived their physical limitations in daily life activities. An explorative and qualitative design with a phenomenographic approach was chosen, a total of 15 patients were interviewed. The findings indicate that participants perceived a variety of structural aspects pertaining to physical limitations in activities of daily life which resulted in four referential aspects. Need of finding practical solutions in daily life focused on how life had to be changed and other ways of performing activities of daily life had to be invented. Having realistic expectations about the future was characterised by belief that the future itself would be marked by change in physical functioning, but an incentive to maintain functions and activities ensured good quality of or even increased capacity in daily life. Not believing in one’s own ability included the perception of having no opportunity to improve ability to perform activities of daily life. There were perceptions of undesired passivity, undefined fear of straining themselves or performing activities that could endanger their health in addition to uncertainty about the future. In Losing one’s social role in daily life, participants described losing their social network and their position in society and family because of limited physical capacity. A lack of important issues, mental and physical, occurred when physical capacity was lost. In conclusion, patients suffering from chronic heart failure found new solutions to manage activities in daily life, including willingness to change focus and identify other ways of doing important things. Patients had an incentive to maintain functions and activities to ensure a good quality of and strengthen their physical capacity in daily life. Inability to trust in their physical capacity in combination with experienced limitations in daily life prevented patients from attempting to increase activities. 相似文献

BackgroundSelf-management approaches are widely used to improve chronic care. In this context, health care professionals call for efficient tools to engage patients in managing their illness. Mobile health (mHealth), defined by WHO as medical and public health practice supported by mobile devices, is demonstrated to enhance self-management and health-coaching as an engaging tool in supporting behaviour change. Nevertheless, it is unclear how health-coaching and mHealth can benefit from each other.ObjectiveWe conducted a scoping review to provide a literature-overview and identify any existing gaps in knowledge of mHealth in combination with health-coaching interventions for improving self-management in patients with chronic diseases.Patient involvementNo patients were involved in the review process.MethodsThe five-stage framework by Arksey and O'Malley was used. The review surveys; PubMed, CINAHL, Embase, Scopus, and PsycInfo. Two independent reviewers performed review selection and characterization.ResultsThe review points at two approaches; (i) coaching used to support mHealth and (ii) mHealth as support for coaching. The findings suggest that patients prefer physical interactions to telecommunication. mHealth was primarily used to facilitate telecommunication and to monitor disease aspects.DiscussionWe found that mHealth and health-coaching interventions benefit from each other. The review report on a considerable unclarity in the coaching-methods and that the patients were more satisfied with physical interactions than mHealth. We suggest to prioritize human contact and to explore more personalized health technology.Practical valueThis scoping review can provide a framework for researchers and care providers to support discussion and introduction of new approaches and technology in self-management for patients with chronic diseases, thereby improving patients’ quality of life. 相似文献
