Dysfunctional attitudes and poor problem solving skills predict hopelessness in major depression.

BACKGROUND: Hopelessness is a significant predictor of suicidality, but not all depressed patients feel hopeless. If clinicians can predict hopelessness, they may be able to identify those patients at risk of suicide and focus interventions on factors associated with hopelessness. In this study, we examined potential predictors of hopelessness in a sample of depressed outpatients. METHODS: In this study, we examined potential demographic, diagnostic, and symptom predictors of hopelessness in a sample of 138 medication-free outpatients (73 women and 65 men) with a primary diagnosis of major depression. The significance of predictors was evaluated in both simple and multiple regression analyses. RESULTS: Consistent with previous studies, we found no significant associations between demographic and diagnostic variables and greater hopelessness. Hopelessness was significantly associated with greater depression severity, poor problem solving abilities as assessed by the Problem Solving Inventory, and each of two measures of dysfunctional cognitions (the Dysfunctional Attitudes Scale and the Cognitions Questionnaire). In a stepwise multiple regression equation, however, only dysfunctional cognitions and poor problem solving offered non-redundant prediction of hopelessness scores, and accounted for 20% of the variance in these scores. LIMITATIONS: This study is based on depressed patients entering into an outpatient treatment protocol. All analyses were correlational in nature, and no causal links can be concluded. CONCLUSIONS: Our findings, identifying clinical correlates of hopelessness, provide clinicians with potential additional targets for assessment and treatment of suicidal risk. In particular, clinical attention to dysfunctional attitudes and problem solving skills may be important for further reduction of hopelessness and perhaps suicidal risk.

Emergence of adverse events following discontinuation of treatment with extended-release venlafaxine.

OBJECTIVE: The rate of adverse events following discontinuation of treatment with extended-release venlafaxine was compared with the rate associated with discontinuation of placebo administration. METHOD: The subjects were 20 outpatients with major depressive disorder who had participated in a multicenter, double-blind, placebo-controlled study of the efficacy of the new extended-release formulation of venlafaxine. RESULTS: During the 3 days after discontinuation of treatment with the study drug, seven (78%) of the nine venlafaxine-treated subjects and two (22%) of the nine placebo-treated patients reported the emergence of adverse events, a statistically significant difference. CONCLUSIONS: These results suggest that clinicians discontinuing venlafaxine treatment should consider tapering the medication dose gradually.

Bone ingrowth into a low-modulus composite plastic porous-coated canine femoral component.

Bone ingrowth into low-modulus canine femoral components made of composite plastics and porous coated with titanium fiber mesh was evaluated and compared to that found in femoral components of the same design made of titanium alloy and porous coated with titanium fiber mesh. Both types of components demonstrated extensive bone ingrowth into the porous coatings at 6 weeks and there were no differences in the histologic appearance of the tissue ingrowth in the two groups. The amount of bone that grew into the porous surface, the areal density of bone within the available pore space, and the extent of the prosthesis periphery with bone ingrowth were not significantly varied in the two different components. The results of this study show that adequate fixation of low-modulus composite femoral components porous coated with titanium fiber mesh by bone ingrowth can occur and that further investigation of these materials for femoral components may be warranted.

General practitioner and long term care of patients with a spinal injury.

A questionnaire was sent to disabled people to ascertain what part their general practitioners played in their long term care. The average consultation rate was 4.40 per patient a year. Overall, it appeared that the patients were most concerned with the general practitioner's attitude towards them and the general practitioner's availability.

Ancillary staff in general practice.

The results of a questionnaire answered by 70 secretary-receptionists in general practice are analysed. Variations in their rates of pay are described. Lack of inservice training appears to result more from paucity of opportunity than lack of enthusiasm of the secretaries themselves.

Iatrogenic disease in general practice: its incidence and effects.

A year's survey of iatrogenic disease in general practice showed that one consultation in every 40 was the result of iatrogenic disease. Iatrogenic disease may affect the doctor/patient relationship, often leading the doctor to feel guilty or the patient to become aggressive.

Borderline indications for use of cement in total joint replacements.

In order to delineate the borderline indications for the cemented and uncemented total hip replacements, we need to evaluate the existing success rates with these procedures. The long term success rates with cemented total hip replacements done using an intramedullary methylmethacrylate plug, doughy Simplex bone cement introduced in a retrograde fashion via a cement gun, and collared cobalt-chrome femoral components with rounded corners were reviewed at eleven year follow-up. The patients ranged in ages from 20 to 84 years (mean 57 years). Among the 105 patients in the group followed up at a minimum of 10 years 97% of the femoral components remained rigidly fixed. These results suggest that the cemented femoral components give satisfactory results to the vast majority of patients over eleven years. Further improvements in the use of cement for prosthetic fixation were made since then. The strength of the cement-prosthesis interface is now considerably enhanced by precoating the prosthesis industrially with a thin layer of methacrylate and or by using texture prosthesis. The strength of cement is considerably improved by techniques such as centrifuging the cement after mixing, or mixing the cement in vacuum. These techniques appear promising and may further enhance the fixation of the prostheses to the skeleton.
