Association between symptoms and quality of life in patients with schizophrenia: a pooled analysis of changes over time

Quality of life is an important outcome in the treatment of patients with schizophrenia. It has been suggested that patients' quality of life ratings (referred to as subjective quality of life, SQOL) might be too heavily influenced by symptomatology to be a valid independent outcome criterion. There has been only limited evidence on the association of symptom change and changes in SQOL over time. This study aimed to examine the association between changes in symptoms and in SQOL among patients with schizophrenia. A pooled data set was obtained from eight longitudinal studies that had used the Brief Psychiatric Rating Scale (BPRS) for measuring psychiatric symptoms and either the Lancashire Quality of Life Profile or the Manchester Short Assessment of Quality of Life for assessing SQOL. The sample comprised 886 patients with schizophrenia. After controlling for heterogeneity of findings across studies using linear mixed models, a reduction in psychiatric symptoms was associated with improvements in SQOL scores. In univariate analyses, changes in all BPRS subscales were associated with changes in SQOL scores. In a multivariate model, only associations between changes in the BPRS depression/anxiety and hostility subscales and changes in SQOL remained significant, with 5% and 0.5% of the variance in SQOL changes being attributable to changes in depression/anxiety and hostility respectively. All BPRS subscales together explained 8.5% of variance. The findings indicate that SQOL changes are influenced by symptom change, in particular in depression/anxiety. The level of influence is limited and may not compromise using SQOL as an independent outcome measure.

Effects of acupuncture and Chinese herbal medicine (Zhi Mu 14) on hot flushes and quality of life in postmenopausal women: results of a four-arm randomized controlled pilot trial

OBJECTIVE: The aim of this study was to evaluate the feasibility of a clinical trial investigating the effects of acupuncture (AP) and Chinese herbal medicine (CHM) on hot flushes and quality of life in postmenopausal women. METHODS: Forty postmenopausal women reporting at least 20 hot flushes per week were enrolled in a randomized controlled trial. They were randomly allocated to receive traditional Chinese medicine (TCM) AP, sham AP, verum CHM, or placebo CHM for 12 weeks. Follow-up assessment was conducted 12 weeks after intervention. Primary outcome measures included hot flush frequency and severity. As a secondary outcome measure, the severity of menopausal symptoms was assessed using the Menopause Rating Scale (MRS) II. RESULTS: TCM AP induced a significant decline in all outcome measures from pretreatment to posttreatment compared with sham AP (hot flush frequency, P = 0.016; hot flush severity, P = 0.013; MRS, P < 0.001). In the TCM AP group, a larger decrease in MRS scores persisted from pretreatment to follow-up (P = 0.048). No significant differences were noted between the verum CHM group and the placebo CHM group. Compared with the verum CHM group, there was a significant decrease in MRS scores (P = 0.002) and a trend toward a stronger decrease in hot flush severity (P = 0.06) in the TCM AP group from pretreatment to posttreatment. CONCLUSIONS: TCM AP is superior to sham AP and verum CHM in reducing menopausal symptoms, whereas verum CHM shows no significant improvements when compared with placebo CHM.

The purpose of this article is to compare quality of life (QOL) and menopausal symptoms among premenopausal patients with lymph node-negative breast cancer receiving chemotherapy, goserelin, or their sequential combination, and to investigate differential effects by age.

Safety and exercise tolerance of acute high altitude exposure (3454 m) among patients with coronary artery disease

OBJECTIVES: To assess the safety and cardiopulmonary adaptation to high altitude exposure among patients with coronary artery disease. METHODS: 22 patients (20 men and 2 women), mean age 57 (SD 7) years, underwent a maximal, symptom limited exercise stress test in Bern, Switzerland (540 m) and after a rapid ascent to the Jungfraujoch (3454 m). The study population comprised 15 patients after ST elevation myocardial infarction and 7 after a non-ST elevation myocardial infarction 12 (SD 4) months after the acute event. All patients were revascularised either by percutaneous coronary angioplasty (n = 15) or by coronary artery bypass surgery (n = 7). Ejection fraction was 60 (SD 8)%. beta blocking agents were withheld for five days before exercise testing. RESULTS: At 3454 m, peak oxygen uptake decreased by 19% (p < 0.001), maximum work capacity by 15% (p < 0.001) and exercise time by 16% (p < 0.001); heart rate, ventilation and lactate were significantly higher at every level of exercise, except at maximum exertion. No ECG signs of myocardial ischaemia or significant arrhythmias were noted. CONCLUSIONS: Although oxygen demand and lactate concentrations are higher during exercise at high altitude, a rapid ascent and submaximal exercise can be considered safe at an altitude of 3454 m for low risk patients six months after revascularisation for an acute coronary event and a normal exercise stress test at low altitude.

Safety and outcome of patients with an acute ST-elevation myocardial infarction transferred for primary coronary intervention: the Neuchâtel experience

BACKGROUND: Transferring patients with ST-elevation myocardial infarction (STEMI) for primary percutaneous coronary intervention (PCI) from a community hospital to a PCI centre has been evaluated in randomised trials and shown to be safe and effective. A prolonged transfer time may restrict the benefit of this strategy. AIM: We sought to assess 1) safety of transfer from Neuchâtel to Berne, 2) time intervals of patients transferred either directly from on-site or after evaluation in the local emergency room, and 3) clinical long-term outcome. METHODS AND RESULTS: 42 patients with STEMI eligible for reperfusion therapy were prospectively included between January 2003 and June 2004. Twenty patients (48%, group 1) were directly transferred to the PCI centre from on-site. Twenty-two were transferred after initial treatment in the local emergency room: 11 patients (26%, group 2) presented spontaneously at the hospital and 11 patients (26%, group 3) were admitted by the rescue team. No major complication occurred during transport. Median transport time was 33 minutes. Median time from first healthcare contact to balloon consisted of 131 minutes in group 1, 158 minutes in group 2 and 174 minutes in group 3. The overall rate of Major Adverse Cardiac Events (MACE) at 6 months amounted to 9.5%. CONCLUSIONS: Transfer for primary PCI of our patients with acute STEMI was safe. Direct transfer from on-site to the PCI centre reduced the time of ischaemia. The overall MACE rate was low.

Impact of Helicobacter pylori eradication on dyspepsia, health resource use, and quality of life in the Bristol helicobacter project: randomised controlled trial

OBJECTIVE: To determine the impact of a community based Helicobacter pylori screening and eradication programme on the incidence of dyspepsia, resource use, and quality of life, including a cost consequences analysis. DESIGN: H pylori screening programme followed by randomised placebo controlled trial of eradication. SETTING: Seven general practices in southwest England. PARTICIPANTS: 10,537 unselected people aged 20-59 years were screened for H pylori infection (13C urea breath test); 1558 of the 1636 participants who tested positive were randomised to H pylori eradication treatment or placebo, and 1539 (99%) were followed up for two years. INTERVENTION: Ranitidine bismuth citrate 400 mg and clarithromycin 500 mg twice daily for two weeks or placebo. MAIN OUTCOME MEASURES: Primary care consultation rates for dyspepsia (defined as epigastric pain) two years after randomisation, with secondary outcomes of dyspepsia symptoms, resource use, NHS costs, and quality of life. RESULTS: In the eradication group, 35% fewer participants consulted for dyspepsia over two years compared with the placebo group (55/787 v 78/771; odds ratio 0.65, 95% confidence interval 0.46 to 0.94; P = 0.021; number needed to treat 30) and 29% fewer participants had regular symptoms (odds ratio 0.71, 0.56 to 0.90; P = 0.05). NHS costs were 84.70 pounds sterling (74.90 pounds sterling to 93.91 pounds sterling) greater per participant in the eradication group over two years, of which 83.40 pounds sterling (146 dollars; 121 euro) was the cost of eradication treatment. No difference in quality of life existed between the two groups. CONCLUSIONS: Community screening and eradication of H pylori is feasible in the general population and led to significant reductions in the number of people who consulted for dyspepsia and had symptoms two years after treatment. These benefits have to be balanced against the costs of eradication treatment, so a targeted eradication strategy in dyspeptic patients may be preferable.

Aortic root replacement does not affect outcome and quality of life

BACKGROUND: Different studies have analyzed the potential impact of the underlying pathologic process and the use of deep hypothermic circulatory arrest on outcome and quality of life after surgery on the thoracic aorta. The aim of this study is to analyze the impact of different surgical procedures on outcome and quality of life. METHODS: Between June 2001 and December 2003, 244 patients underwent surgery for various diseases of the ascending aorta with or without involvement of the aortic valve or root. They were divided according to the operative procedure: 76 patients (31.2%) underwent isolated replacement of the ascending aorta, 42 patients (17.2%) received separate aortic valve replacement and supracoronary replacement of the ascending aorta, 86 patients (35.2%) received a mechanical composite graft, and 40 patients (16.4%) received a biologic composite graft. All in-hospital data were assessed, and a follow-up was performed in all survivors after 26.6 +/- 8.8 months, focusing on outcome and quality of life (SF-36). RESULTS: Overall in-hospital mortality was 6.1%, and late mortality was 5.7%, with no significant difference between groups. Independent of the surgical technique and the extent of surgery, there was no difference in quality of life between the surgical collective and an age-matched and sex-matched standard population. CONCLUSIONS: Operations of the ascending aorta and aortic valve are very safe, with low in-hospital mortality and favorable midterm outcome regarding late mortality and morbidity. Quality of life after operations of the ascending aorta and aortic valve is equal to a standard population and is not affected by the surgical procedure. Liberal use of aortic root replacement is therefore justified to radically treat the diseased aortic segment.

A randomized comparison of the safety and efficacy of once-daily gentamicin or thrice-daily gentamicin in combination with ticarcillin-clavulanate

PURPOSE: The primary purpose of the clinical trial was to assess the safety and efficacy of once-a-day compared with three-times-a-day gentamicin in patients with serious infections who had protocol-determined peak serum aminoglycoside concentrations. PATIENTS AND METHODS: A total of 249 hospitalized patients with suspected or proven serious infections were randomized in a 2:2:1 ratio to gentamicin given three times a day with ticarcillin-clavulanate (TC), gentamicin once a day with TC, or ticarcillin-clavulanate (TC) alone. The gentamicin once-a-day dosage for patients with estimated creatinine clearance values of > or =80 mL/min was 5.1 mg/kg. With lower creatinine clearance estimates, the mg/kg dosage of gentamicin was decreased, and the dosage intervals (once daily or three times a day) were maintained. Evaluability required documentation of achievement of protocol-defined peak serum gentamicin levels. RESULTS: Of the total 175 evaluable patients, there were no significant differences found between treatment regimens with respect to clinical or microbiologic efficacy. Bedside audiometry proved impractical due to the frequency of altered mental state in ill patients. Based on the traditional increase in serum creatinine values from baseline values, no differences in renal toxicity between the treatment groups was identified. When changes in renal function were reanalyzed based on maintaining, as opposed to worsening, of renal function, preservation of renal function was better in the gentamicin once-a-day patients as opposed to the gentamicin three-times-a-day patients, P <0.01. CONCLUSIONS: Gentamicin once a day plus TC, gentamicin three times a day plus TC, and TC alone had similar effects in seriously ill hospitalized patients. The incidence of nephrotoxicity was similar in the three treatment groups. Using a nonvalidated post-hoc analysis, renal function was better preserved in gentamicin once-a-day + TC and TC-only patients as opposed to gentamicin three-times-a-day + TC.
