The psychometric properties of patient preferences in osteoporosis.

OBJECTIVE: Osteoporosis is a chronic disease manifested by wrist, vertebral, and hip fractures that results in significant morbidity and burden to society. About 30% of postmenopausal women have osteoporosis according to the WHO criteria. Women with one vertebral fracture have a 4-fold increased risk of a subsequent fracture. The goal of treatment is to prevent fractures and improve quality of life. Preferences or utilities are now recommended for incorporating quality of life into evaluations of the cost effectiveness of new therapeutic interventions. We evaluated the psychometric properties of preference based measures in osteoporosis. METHODS: Preference scenarios were constructed with a health state classification system. The reliability and validity of the feeling thermometer and the standard gamble was assessed by interviewing 42 women from 4 different patient groups. The sensitivity to change of the feeling thermometer and standard gamble was compared with the Health Utilities Index Mark 2 (HUI2) and SF-36. All subgroups were reassessed about 2 months after their first interview. RESULTS: Preference measurement was feasible in women of different age groups. The reliability coefficients for health states ranged from 0.65 to 0.87. The preference scores for the marker states demonstrated content validity. Convergent validity of the feeling thermometer was supported by a significant correlation with the HUI2 (r = 0.38, p < 0.05) and the physical health summary of the SF-36 (r = 0.56, p < 0.005). The standard gamble did not correlate with the HUI2 (r = 0.15) or the feeling thermometer (r = 0.09), but correlated with 2 domains of the SF-36. The preference measures were sensitive to change, with the efficiency scores ranging from 0.78 to 1.0. CONCLUSION: Preference measurements in the evaluation of osteoporosis are feasible. The feeling thermometer and standard gamble appear to be related to different aspects of health related quality of life. Both instruments were sensitive to change over a 2 month period.

Uterine effects of raloxifene in comparison with continuous-combined hormone replacement therapy in postmenopausal women.

OBJECTIVE: We sought to compare the uterine effects of raloxifene with those of continuous-combined hormone replacement therapy. STUDY DESIGN: This randomized, double-blind 24-month study involved 136 postmenopausal women who received raloxifene 150 mg/d or conjugated equine estrogens 0.625 mg/d with medroxyprogesterone acetate 2.5 mg/d. After baseline evaluations, endometrial biopsy specimens were obtained, and endometrial thickness was measured annually by means of transvaginal ultrasonography. Statistical analyses were performed with an intention-to-treat approach. RESULTS: In the raloxifene group at the end point of the study 94.4% of biopsy specimens showed normal benign postmenopausal endometrium and 5.6% were classified as benign stimulatory endometrium. In the continuous-combined hormone replacement therapy group at the end point of the study 78.7% of biopsy specimens showed normal benign postmenopausal endometrium, 19. 1% were classified as benign stimulatory endometrium, and 2.1% showed benign abnormal postmenopausal endometrium. Mean endometrial thickness was unchanged from baseline with raloxifene and was increased significantly by 0.5 mm at 12 months with continuous-combined hormone replacement therapy. CONCLUSION: Raloxifene 150 mg/d did not increase endometrial thickness or cause endometrial proliferation in healthy postmenopausal women.

A decision aid for women considering hormone therapy after menopause: decision support framework and evaluation.

Although postmenopausal women are advised to consider their values when deliberating about potential benefits and risks of hormone therapy (HRT), feasible, effective methods of decision support in primary care have yet to be established. Using an explicit decision support framework, we developed a self-administered HRT decision aid and evaluated it in a before/after study of 94 women from six family practices. An audiotape guided women through an illustrated booklet including: detailed information about HRT benefits and risks tailored to a woman's clinical risk, and a values clarification exercise to promote informed decision making consistent with personal values. After using the decision aid participants: had better general knowledge and more realistic personal expectations of HRT benefits and risks; and, felt more certain, informed, clear about values, and supported in decision making. Women's values elicited in the clarification exercise were 84% accurate in discriminating between decisions. Women with polarized preferences at baseline did not change their minds, but were better informed. Changes in preferences occurred in the uncertain group, with equal numbers accepting or declining HRT. Most participants found the decision aid comprehensible, acceptable in length and pace, and balanced. Decision aids are useful in preparing women for decision making about this complex, personal issue.

[Acute effect of lorazepam on respiratory muscles in stable patients with chronic obstructive pulmonary disease].

Benzodiazepines are known to cause muscle hypotonia, but their effects on respiratory muscle function, particularly on diaphragm, have not yet been studied. Our aim was to look for any effect of lorazepam on respiratory muscle function in patients with chronic obstructive pulmonary disease (COPD). Nine stable COPD patients (mean +/- SD forced expiratory volume in one second (FEV1) 0.91 +/- 0.31 l) were included in the study. The following measurements were performed before and 1 hour after lorazepam administration (doses: 1.5 to 2 mg) by sublingual route: forced vital capacity (FVC), FEV1, maximal voluntary ventilation (MVV), arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2), minute ventilation (Ve), tidal volume (Vt), respiratory rate (f), inspiratory time/inspiratory plus expiratory time (Ti/Ttot)-, mean inspiratory flow (Vi), maximal inspiratory (MIP) and expiratory (MEP) pressures, maximal pleural pressure (Pplmax), transdiaphragmatic pressures (Pdi) and skeletal muscle strength and endurance. As expected, no change was noted in FVC, FEV1, FEV1/FVC (Table-1). Besides stability of expiratory flows, this denotes no change in collaboration in spite of the sedative effects of lorazepam. There was a 20% decrease in Ve, due to a Vt reduction and a small increase in PaCO2. These could be explained by the central effects of benzodiazepines. Skeletal muscle strength and endurance decreased significantly (22 and 50% respectively-Table 2), in accordance with the previously reported muscular actions of this pharmacological group. Respiratory muscle function parameters, MIP, MEP, MVV and Ppl showed significant reductions (10 to 20 per cent), as was the case with diaphragmatic function measured by Pdi (Muller maneuver with abdominal protrussion and maximal open-glottis expulsive maneuver) (Table 3). This study demonstrates that a single lorazepam dose reduces strength and endurance of respiratory muscle in chronic stable COPD patients.

[Cytologic changes in bronchoalveolar lavage in amiodarone treated patients].

The histologic evidence of amiodarone pulmonary toxicity is interstitial pneumonia with foamy alveolar macrophages, which ultrastructurally show lamellar inclusion bodies due to lipid storage. Bronchoalveolar lavage (BAL) fluid findings include foamy macrophages, considered characteristic, and, in certain patients, differential cell counts suggestive of active alveolitis, giving rise to an immunologic explanation for its origin. The present study was undertaken in order to investigate the findings in BAL fluid in nontoxic patients taking amiodarone and to evaluate their clinical relevance. Eleven patients taking amiodarone chlorhydrate for severe ventricular arrhythmias (345 +/- 129 mg/day during 46 +/- 31 months and an accumulated dose of 440 +/- 337 g) and without clinical or radiological evidences of pulmonary toxicity, were clinically evaluated and studied by BAL. As shown in Table 1, cough and pulmonary rales were common findings (64% and 36% respectively), chest X-Rays were normal or indicative of cardiac failure and arterial blood gases showed slight hypoxemia (PaO2 83 +/- 10). As these are usual findings in advanced cardiac diseases, the patients were considered as having no amiodarone toxicity. BAL was done and the fluid obtained was processed for cytologic study. In every patient foamy macrophages were seen with light microscopy and lamellar bodies were detected by electron microscopy. In 5/10 evaluable patients BAL fluid cell count disclosed an increase in lymphocytes, leukocytes or both, indicative of alveolitis. This group of patient had lower PaO2 and PaO2/PAO2 than "non alveolitic" patients (76 +/- 9 mmHg vs 89 +/- 5 mmHg and 0.72 +/- 0.1 vs 0.85 +/- 0.08 - p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Primary thrombocythemia in pregnancy: a report of two cases.

We report two cases of primary thrombocythemia diagnosed during pregnancy. One patient developed transient visual field defects. She was treated with plateletpheresis at term and delivered of a normal child by cesarean section. The second patient was not treated. Intrauterine fetal death occurred at 36 weeks' gestation from multiple placental infarcts. In cases of primary thrombocythemia, we suggest close monitoring of both mother and fetus throughout pregnancy.

Genetic counseling, a health department service to physicians.

Questions about inheritance in all kinds of diseases and defects are commonly asked of nearly all physicians. In attempting to answer these questions, however, the physician is often hampered by lack of formal instruction in clinical genetics. Since the health department, if it is to carry out its epidemiologic function, must be as concerned over the increasing identification of genetic agents in disease as it is and has been over environmental disease agents, it should come to represent a source of assistance not now generally available to the physician. In short, as it carries out those activities by which its store of general genetic information is increased, and until other sources of genetic consultation become reasonably available, the health department can be of real service to physicians as a resource to which they may turn for help when dealing with families wanting genetic information. Such a service has been provided experimentally for the last two years by the Contra Costa County Health Department. This program calls for the taking of family pedigrees by public health nurses on families with questions of a genetic nature who are health department clients and on families who are referred by their private physicians for this service. An interpretation of each pedigree is made by the department's physician in charge of the program and submitted to the family's physician for his use in counseling the family. Evidence to date suggests the process can be a highly useful service to the practitioner and his patient.

Randomized trial of a portable, self-administered decision aid for postmenopausal women considering long-term preventive hormone therapy.

Although practice guidelines suggest that postmenopausal women learn about the benefits and risks and consider their values when deciding about hormone therapy, the optimal decision-support method has not been established. In a randomized controlled trial, the authors compared the efficacy of a general educational pamphlet with that of a tailored decision aid. The pamphlet briefly summarized benefits, risks, and likely beneficiaries in general terms. The decision aid, delivered via booklet and audiotape, provided: detailed benefits and risks using functional terms and probabilities tailored to clinical risk; and steps for considering the issue in a woman's own situation, including a value-clarification exercise. Compared with the pamphlet group, the decision-aid group had statistically significant (p < 0.05) improvements in terms of realistic personal expectations of the benefits and risks, decisional conflict, and perceived acceptability of the intervention. Levels of general knowledge about the main benefits and risks were comparable for the two interventions. It is concluded that tailored decision aids prepare women for decision making better than do general pamphlets.
