Evaluation of Communication Aid Centres in England and Wales

This paper reports the findings of an evaluation (funded by the Department of Health) of six Communication Aid Centres established in 1983. The evaluation was undertaken to assess the effectiveness of these Centres in meeting their set objectives, and to examine service costs and client satisfaction. The findings show that the work of each Centre was effective in meeting its stated objectives, but that the work of individual Centres reflected its own specialised interests. Two problems with current funding arrangements were highlighted. First, the need to replace the original funding by locally based finance, and second, the funding of communication aids for clients. The findings also show that the specialist service provided by these Centres can be managed at costs per person assessed at, or below, non-specialist services in health districts. Client satisfaction with the services provided by the Centres was high.     

Effects of high and low anxiety provoking instructions on the responses to the hyperventilation provocation test

This study examined the effect of high and low anxiety provoking instructions in subjects submitted to a Hyperventilation Provocation Test (HVPT). Subjects were 43 out-patients referred to our clinic for a diagnostic examination of Hyperventilation Syndrome (HVS). Results showed that anxiety levels were affected by the instruction manipulation, but the magnitude of this effect was less than expected and the instruction manipulation had no effect on intensity arid type of reproduced symptoms, nor on symptom recognition. Subjects who met Diagnostic and Statistical manual of Mental Disorders (3rd ed., rev,; American Psychiatric Association, 1987) criteria for Panic Disorder (PD) were not more responsive to the instruction manipulation than non-PD patients. It is argued that the small effect of the manipulation is probably not due to the solidity of the HVPT but to the pervasiveness of pretest cognitions and expectations. In line with this, the report of HVS symptoms appeared highly related to psychological trait measures like anxiety, fear of bodily sensations, and a general tendency to report somatic symptoms.     

Hormonal influences on the extinction of conditioned taste aversion

Conditioned taste aversion for a 5% glucose solution (sugar water) was induced in rats by an i.p. injection of LiCl 30 min after the first presentation of sugar water. Extinction of conditioned taste aversion was measured either in the forced-drinking test or in the preference-drinking test. In the forced-drinking test sugar water was the only fluid presented to the animals during extinction sessions. In the preference-drinking test the animals had the choice of tap water or sugar water. The rate of extinction was much slower in the preference test.The ACTH-analogues, ACTH_4–10 and ACTH_{4–10 7D Phe}, and -MSH delayed extinction in the preference test but not extinction in the forced-drinking test. ACTH_11–24 was without any effect. MSH-release inhibiting factor (MIF) facilitated extinction in the forced-drinking test but did not alter extinction in the preference test. The peptides did not affect intake of tap water or preference of sugar water over tap water by control rats.     

Characteristics and outcomes of older patients presenting to the emergency department after a fall: a retrospective analysis

OBJECTIVES: To study older patients presenting to the emergency department after a fall--factors associated with the fall, injuries sustained and outcome. DESIGN: A retrospective analysis using the Emergency Department Information System (EDIS), the Trauma Registry and the patient information database (CCIS), in addition to the patient's emergency and inpatient medical records. SETTING: Emergency department of a major inner city teaching hospital, 1 June-30 November 1997. PATIENTS: All patients over 65 years presenting to the emergency department (ED) after a fall, for whom complete medical records were available. RESULTS: Of 803 patients over 65 years presenting to the ED after a fall, complete records were available for 733 (91.3%) (283 men and 450 women). Extrinsic (accidental) causes were implicated in more than a third of falls (313 patients [42.7%]). A high proportion of the patients were living at home (520; 70.9%) and walking unaided (389; 53.1%). Although absolute numbers of women increased with age, men were as likely as women to present after a fall. Many patients had fallen before--39% of the men (111/283) and 24% of the women (110/450). In 78 patients (10.6%), alcohol misuse may have been a direct cause of the fall. The overall injury rate was 70.5% (517/733 patients), the most common injury being an isolated fracture (269/517 patients; 52.0%). In all, 419 patients (57.2%) were admitted to hospital, 48% (200/419) with a fracture and 52% (219/419) for investigation of the medical cause of the fall. The median length of hospital stay was 6 days (mean, 10.4 days; range, 1-129 days); 35% (146/419) of patients were in hospital for more than 10 days. CONCLUSION: Older patients presenting to the ED after a fall had high injury rates, high admission rates and often prolonged hospitalisation. About a third had fallen before. Patients at risk can be identified in the ED and referred to falls prevention programs.     

Lower dose capecitabine has a more favorable therapeutic index in metastatic breast cancer: retrospective analysis of patients treated at M. D. Anderson Cancer Center and a review of capecitabine toxicity in the literature.

BACKGROUND: Capecitabine is active against anthracycline- and taxane-pretreated metastatic breast cancer. Post-marketing use of capecitabine at the FDA-approved dose (2500 mg/m2/day) leads to unacceptable toxicity in many patients. Dose reductions anecdotally improve tolerability without compromising efficacy. This retrospective analysis was designed to verify these anecdotal reports. Patients and methods: We retrospectively reviewed the records of 141 consecutive patients with metastatic breast cancer identified from pharmacy records as receiving capecitabine outside of a clinical trial between May 1998 and February 1999. Responses were defined as clinical improvement (ID), stabilization of disease (SD) for 6 weeks or longer, or progression (PD). Patients were grouped according to the starting dose level of capecitabine: A=2500+/-5% (dose range 2385-2560) mg/m2/day; B=2250+/-5% (range 2130-2350) mg/m2/day; C < or = 2000+5% (range 1000-2100) mg/m2/day. We also reviewed the safety profile of capecitabine at these doses and performed a safety review of capecitabine in phase II and III metastatic breast and colorectal cancer trials. RESULTS: Clinical data were available for 113 patients (105 for response, 106 for toxicity). The median age was 52.5 years and the mean number of prior metastatic chemotherapy regimens was 2 (range 0-7). The mean capecitabine starting dose was 2220 mg/m2/day and the median number of cycles administered was 4 (range 1-19). The mean tolerated dose was 2040 mg/m2/day (range 960-2670). Grade 3/4 toxic effects at dose levels A, B and C, respectively, included palmar-plantar erythrodysesthesia (33%, 63%, 20%), diarrhea (13%, 12%, 3%), stomatitis (8%, 0%, 3%), and nausea/vomiting (4%, 6%, 5%). Forty per cent of all patients required capecitabine dose reductions; fewer patients treated with 2000 mg/m2/day required dose modification (28%). Five per cent of the patients required discontinuation of capecitabine owing to toxicity. Patients started at the lowest doses of capecitabine did not have poorer response rates or shorter time to progression. CONCLUSIONS: This retrospective analysis supports a starting dose of 2000 mg/m2/day because of its superior therapeutic index; however, patients may still have toxic effects and individualization of dosing is necessary. A phase III, multicenter, randomized study to establish the safety and efficacy of different doses of capecitabine is urgently needed.     

RCAM: a proposed model of recovery capital for adolescents

Problematic substance use is a challenge worldwide among adolescents. The recovery process requires holistic support addressing multiple and intersecting substance use risk factors; yet, there remains a lack of evidence on how to best understand and support adolescents in recovery. Recovery capital (RC) is a model that can be used to identify areas of assets that could be enhanced and barriers to address in one’s recovery process; however, this construct was generated through a study of adults who achieved natural recovery and it has since been used to frame adult recovery-related literature across the world. The primary aim of this article is to outline the rationale for and present a Recovery Capital for Adolescents Model (RCAM). The article will discuss the original recovery capital model, describe adolescent development, substance use, and recovery, and detail proposed developmental adaptations. Future qualitative and quantitative research should explore the RCAM to assess whether the proposed dimensions are complete as well as to assess its utility in clinical settings for identifying strengths and barriers for adolescents in or seeking recovery.
