Agonistic screams in wild chimpanzees (Pan troglodytes schweinfurthii) vary as a function of social role.

Some nonhuman primates have demonstrated the capacity to communicate about external objects or events, suggesting primate vocalizations can function as referential signals. However, there is little convincing evidence for functionally referential communication in any great ape species. Here, the authors demonstrate that wild chimpanzees (Pan troglodytes schweinfurthii) of Budongo forest, Uganda, give acoustically distinct screams during agonistic interactions depending on the role they play in a conflict. The authors analyzed the acoustic structure of screams of 14 individuals, in the role of both aggressor and victim. The authors found consistent differences in the acoustic structure of the screams, across individuals, depending on the social role the individual played during the conflict. The authors propose that these 2 distinct scream variants, produced by victims and aggressors during agonistic interactions, may be promising candidates for functioning as referential signals.

The relationship of premorbid functioning to illness course in schizophrenia and psychotic mood disorders during two years following first hospitalization.

Studies suggest that better premorbid functioning is associated with better outcomes in chronic schizophrenia. Yet first admission studies, which are more appropriate to examine this, are less conclusive. Also, little attention has been given to whether these findings hold for other psychoses. We examined the relationship of premorbid functioning using the Premorbid Adjustment Scale and outcomes in first admission psychoses (schizophrenia, N = 177; bipolar disorder, N = 106; major depression, N = 68) in the Suffolk County-wide mental health project. Poor premorbid functioning was associated with worse outcomes in all three diagnostic groups. Specifically, it was associated with more negative symptoms early in the course of illness, less improvement in negative symptoms, poorer overall clinical functioning, and poorer social functioning. Consistent with new epidemiological research, early assessment of premorbid functioning could provide an avenue for targeted interventions that might improve outcomes.

Is health status related to residence in medically underserved areas? Evidence and implications for policy.

This study sought to compare the health status of adult residents of medically underserved areas (MUAs) with adult residents of nonshortage areas (non-MUAs). A random digit dialing telephone survey was used. Respondents were subsequently classified by their county of residence as residing in an MUA or non-MUA. A sample of 421 adults (aged 18 years or older) residing in Kentucky during 1993 were included in the analysis. Health status was measured by the Medical Outcomes Study 20-item Short-Form Health Survey's (SF-20) six subscales. After controlling in the multiple regression for demographic variables there were no significant differences between residents of MUAs and non-MUAs for the physical functioning, role functioning, general mental health, self-perception of health, or pain subscales. The social functioning subscale was significantly related to the residence in an MUA. The demographic variable "education" was a consistent predictor of each of the health status subscales. Excepting the social functioning subscale, residents of MUAs do not have significant differences in health status when compared to residents of non-MUAs. Future policy may need to focus on other health services shortage area designators that are more highly associated with the health status of residents. Consideration should be given to including the education demographics of areas or populations in health services shortage designation criteria.

Factors predicting fractures during falling impacts among home-dwelling older adults.

OBJECTIVE: To investigate the predictors of fractures during falling impacts among home-dwelling older adults. DESIGN: A case-control study within a prospective, population-based survey. SETTING: Five rural municipalities in northern Finland. PARTICIPANTS: The study population consisted of all home-dwelling persons aged 70 or older living in these five municipalities (n = 790 (85%)). The cases for this study were those with fracture, using the first fracture (n = 82) in the analyses, during a follow-up period of 4 years. Controls (n = 82) were selected from among the persons who suffered soft tissue injuries; matching was by age, sex, and location of the first injury during the period. MEASUREMENTS: During a 4-year follow-up period, all falls in the population were recorded using fall diaries, telephone interviews, and information from medical records. Risk factors for fractures during the 4-year follow-up were determined according to the number and severity of previous falls, circumstances and place of falls, disease history, use of medicines, symptoms, clinical examinations and tests, nutritional status, functional abilities and social and health behavior. Cross-tabulations for categorial variables, paired t tests for the means of continuous variables, and conditional logistic regression analysis were performed. RESULTS: According to the bivariate analyses, the risk factors for falls resulting in a fracture were frequent fear of falling, abnormal heel-shin test, reduced knee extension strength, reduced grip strength, poor distance visual acuity, low supine pulse rate, inability to carry a 5-kg load 100 meters, not doing heavy outdoor work, and no habitual exercise. A limited amount of social participation was associated negatively with fracturing. Conditional logistic regression analysis showed that the risk factors for fracture-causing falls were frequent fear of falling (OR 2.50; CI 1.11-5.65), reduced knee extension strength (OR 3.38; CI 1.00-11.4), and poor distance visual acuity (OR 3.45; CI 1.13-10.6), whereas limited social participation (OR 0.29; CI 0.11-0.79) protected against the occurrence of fractures. CONCLUSION: Impaired perception, muscle strength, and psychological and social functioning may influence fracture risk during injurious fall impacts. Studies with larger sample sizes are needed to confirm this and to examine the circumstances and mechanisms contributing to the fracture risk during falls via these risk factors.

The impact of nausea and vomiting on women: a burden of early pregnancy.

Nausea and vomiting are troublesome symptoms occurring in the first trimester of pregnancy. The aim of this study was to describe the impact these symptoms have on women in early pregnancy by interviewing, using a structured questionnaire, 593 pregnant women presenting with nausea and vomiting in the first trimester of pregnancy. The women were asked to complete the Rhodes index of nausea and vomiting and the MOS 36 Short Form Health Survey (SF-36). Symptoms of nausea and vomiting started early in pregnancy. Nausea was the most troublesome symptom experienced by women, both in its duration and intensity. Low scores for the SF-36 were found for all items, particularly physical functioning, energy and social functioning. The women described substantial effects on working, household duties and parenting activities. Findings from this study suggest nausea and vomiting in early pregnancy has a profound impact on women's general sense of well-being and day to day life activities.

Late-onset Pompe disease primarily affects quality of life in physical health domains.

OBJECTIVE: To investigate quality of life in an international population of patients with late-onset Pompe disease. METHODS: Data on quality of life (SF-36), age, sex, disease duration, wheelchair use, and use of artificial ventilation were collected for 210 adults with Pompe disease from Australia, Germany, the Netherlands, the United Kingdom, and the United States. SF-36 scores were compared between countries and related to patient characteristics. In addition, for the Dutch subgroup (n = 51), comparisons with the general population and 1-year follow-up assessments were performed. RESULTS: No significant differences between countries were found for the four physical health scales. Mean scores on the vitality, role functioning-emotional, and mental health scale differed between countries, but these differences were not consistent. Wheelchair use was associated with lower physical and social functioning scores (B = -23.6 and -15.1, p < 0.001), and the use of artificial ventilation with lower physical functioning scores (B = -8.4, p = 0.004). Patients reported significantly poorer quality of life than the general population on the physical functioning, role functioning-physical, general health, vitality, and social functioning scales. No significant differences in SF-36 scores were found between the baseline and 1-year follow-up measurement. CONCLUSIONS: Patients with late-onset Pompe disease are, on average, markedly affected on the physical health domains of quality of life, but score only slightly lower than the general population on the mental health domains.

[A model of the levels of functioning for psychiatric medicosocial expertise].

Based on the examination of 302 schizophrenic patients there have been established criteria for assessment of social functioning of mental patients. The clinical model holds nine levels of functioning. Assessment criteria will, we believe, help in bringing off unanimity as to definition of levels of social functioning, developing programmes of rehabilitation of disabled persons tailored to the individual, assessing the efficiency of exposure to medical-rehabilitative treatments over time.

CSF dopamine beta-hydroxylase in schizophrenia: associations with premorbid functioning and brain computerized tomography scan measures.

OBJECTIVE: The authors attempted to replicate previous findings of relationships of CSF dopamine beta-hydroxylase with premorbid functioning and computerized tomography (CT) scan measures in a new cohort of schizophrenic patients. METHOD: Data on CSF dopamine beta-hydroxylase-like immunoreactivity and premorbid functioning, as well as CT scans, were obtained in 60 drug-free, male schizophrenic patients and two groups of normal comparison subjects. RESULTS: CSF dopamine beta-hydroxylase did not differ between the comparison subjects and schizophrenic patients. Lower CSF dopamine beta-hydroxylase was associated with better premorbid social functioning and with less prefrontal sulcal widening. Better premorbid school functioning and more years of education, however, were associated with higher CSF dopamine beta-hydroxylase. CONCLUSIONS: The association between low CSF dopamine beta-hydroxylase and premorbid functioning was confirmed for social functioning, while the opposite was observed for scholastic performance, suggesting that these are different dimensions. Dopamine beta-hydroxylase modulates the prognosis and potentially the course of schizophrenia without necessarily causing the disorder.

Secondary prevention of depressive symptoms in elderly inhabitants of residential homes.

The effects of a multifaceted secondary prevention intervention in residential homes in the Netherlands were examined, using a quasi-experimental design. In five experimental residential homes, the caregivers received three training sessions on detecting depression and on supporting depressed residents. Furthermore, an information session was organized for all personnel, a further session was organized for residents and their relatives, and several group interventions were offered. 213 residents participated in the study. 211 residents of five other residential homes, matched on basic variables, served as a comparison group. Effects on depressive symptoms (geriatric depression scale) and health related quality of life (MOS-SF-36) were measured at pretest and after the intervention, one year later. Because the drop-out rate was high and drop-outs differed significantly from the remaining population, the scores of drop-outs were imputed. Since we used a quasi-experimental design, we controlled for confounding variables. Regression analyses resulted in significant effects of the intervention on the GDS and on role functioning in the total population. When the analyses were limited to those scoring high on the GDS at pretest, significant effects were found on the GDS, and on four domains of health-related quality of life: psychological distress, role functioning, pain and social functioning. The improvement in GDS scores in GDS cases was significantly larger than in other subjects. Our results suggest that general approaches aimed at a residential home are capable of influencing depressive symptoms in inhabitants. Possibly, it may not be necessary to wait until depressive symptoms have escalated and inhabitants need extensive treatment.

An exploration of patients' experiences of anti-TNF therapy.

OBJECTIVE: To explore the experience of rheumatoid arthritis patients receiving anti-tumour necrosis factor (anti-TNF) therapy on physical, psychological and social well-being. METHOD: Seven patients with rheumatoid arthritis (RA) who received six months of infliximab were interviewed in depth by one researcher to identify their experiences of this treatment. The interviews were tape-recorded and analysed using Colaizzi's procedural steps. RESULTS: Four main categories were identified from the interview relating to the patient's experience of anti-TNF therapy. These included: The impact of living with RA on physical, psychological and social function. The influence of anti-TNF therapy on physical, psychological and social function. The experience of attending for treatment. The impact of discontinuing anti-TNF treatment. CONCLUSION: All seven patients experienced benefits from receiving anti-TNF therapy. These benefits were not maintained once the treatment period was completed.

The use of two measures of health-related quality of life in HIV-infected individuals: a cross-sectional comparison.

Two measures of health-related quality of life in 65 HIV-infected individuals were compared in a cross-sectional design. The Quality of Well-Being Scale (QWB) results in a single score ranging from death to perfect health. The MOS-HIV Health Survey (MOS-HIV, 34-item version) gives scores in 11 dimensions. The QWB score distinguished subjects with AIDS from those who were asymptomatic (p = 0.027). For the seven multi-item scales of the MOS-HIV, Cronbach's alpha ranged from 0.85-0.95, indicating good internal consistency reliability. Clinical HIV-infection status was significantly associated with the dimensions of Overall Health (p = 0.002), Role Function (p = 0.022), Social Function (p = 0.037), Energy/Fatigue (p = 0.027) and Health Distress (p = 0.025). All eleven dimensions of the MOS-HIV were significantly correlated with the QWB score (Spearman's coefficient = 0.405-0.670; for all, p < 0.01) and the QWB score could be predicted from the MOS-HIV dimension scores using multiple regression. The QWB and the MOS-HIV may be useful in assessing health-related quality of life in patients infected with HIV.

Quality of life in ambulatory postmenopausal women: the impact of reduced bone mineral density and subclinical vertebral fractures.

Health-related quality of life (HRQOL) in postmenopausal women with osteoporosis has hitherto been mainly assessed in patients with clinically recognized vertebral fractures. Our study aimed to investigate the QOL perception in 361 asymptomatic ambulant postmenopausal women who came to our center for an osteoporosis screening program planned with their general practitioners. The Quality of Life Questionnaire of the European Foundation for Osteoporosis (QUALEFFO) was administered to all subjects. The participants underwent bone mineral density (BMD) measurements by DXA of either the lumbar spine and/or the femoral neck, as well as X-ray examination of the thoracolumbar spine to identify subclinical vertebral fractures. According to the WHO definition, where subjects are subdivided by BMD values into three groups (women with normal BMD, osteopenia, and osteoporosis), a significant difference was found only for the domains which explore general health perception (p<0.01 by ANOVA) and mental function (p<0.001 by ANOVA). When we segregated both osteopenic and osteoporotic women according to whether or not they had vertebral fractures, a significant difference was found only in osteoporotic patients for domains which explore physical function (p<0.001), social function (p<0.001), general health perception (p<0.02), and total QUALEFFO score (p<0.01). Stepwise multiple logistic regression analysis of the whole sample showed that both vertebral fractures and a low femoral BMD impairs QOL perception, while age did not exert a significant influence. ROC curves analysis demonstrated a low discriminating capacity of individual domains and total QUALEFFO score for both vertebral deformities and BMD categorization. Our results showed that QUALEFFO is not able to discriminate between patients with or without subclinical vertebral fractures. However, some aspects of QOL appear to be impaired in patients with subclinical vertebral fractures or reduced BMD.

The severity of vertebral fractures and health-related quality of life in osteoporotic postmenopausal women.

Vertebral fractures are the hallmark of osteoporosis, responsible for increased back pain, impairment of mobility and functional limitations. These factors have an impact on patients' health-related quality of life (QOL). The aim of this study was to assess QOL, using QUALEFFO, in osteoporotic postmenopausal women, according to the number and the severity of the vertebral fractures. A group of 629 osteoporotic postmenopausal women (60-80 years) with symptoms that, according to a rheumatologist, could be related to a vertebral fracture, had spine X-rays with standardized procedures. All the X-rays were assessed in a central facility. The number of fractures was a determinant of a low QOL, as indicated by an increased score in physical function (P=0.001), social function (P=0.002) and total score (P=0.027). Patients with higher grades of vertebral deformities, i.e., more severe fractures, had low QOL in these three domains, too (P<0.0001, P<0.0001 and P=0.005, respectively). There was no difference in QOL according to the thoracic or lumbar location of the fractures. Both anterior and middle deformities of the vertebral bodies had a negative impact on QOL. In none of the analyses were the pain and mental function domains of QUALEFFO discriminant among the patients. QOL, assessed by an osteoporosis-specific instrument, is decreased in osteoporotic women as a function of both the number and the severity of the vertebral fractures. Treating women with prevalent fractures may avoid a further decrease in their quality of life.

The impact of chronic hepatitis C on health-related quality of life in homeless and marginally housed individuals with HIV.

Although infection with Hepatitis C Virus (HCV) and Human Immunodeficiency Virus (HIV) frequently co-exist, there has been little research to determine the effects of HIV/HCV co-infection on health-related quality of life (HRQOL). We performed a cross-sectional analysis of baseline data from 216 participants enrolled in a community based study of HIV-infected homeless and marginally housed individuals, using multivariable linear regression analysis to determine if co-infection with HCV was independently associated with lower short-form 36 (SF-36) questionnaire scores. We found that individuals with HCV had significantly lower mean SF-36 scores in the domains of physical functioning, bodily pain, social functioning and role limitation due to emotional health, and that HIV/HCV co-infection was independently associated with a lower physical component score but not a lower mental component score after controlling for numerous covariates. These results suggest that co-infection with HCV may have an adverse effect on HRQOL among homeless and marginally housed individuals with HIV.

Informed versus blind: the reliability of cross-sectional ratings of psychopathology.

Fifty subjects at the New York facility of the National Institute of Mental Health Clinical Research Branch Collaborative Program on the Psychobiology of Depression were evaluated for cross-sectional psychopathology and functional impairment at the 2-year followup by two professional raters, one blind and one with extensive knowledge of the subject's psychiatric history and course of illness and treatment (the cohort rater). Ratings were made on the change version of the Schedule for Affective Disorders and Schizophrenia. Interrater reliability, as tested using the intraclass correlation coefficient, was quite good for most of the symptom ratings and fair on measures of functional impairment and social functioning. However, there was a consistent tendency for the blind rater to score higher levels on symptoms of depression and anxiety than the informed cohort rater. Reasons for disagreement in different symptom areas are discussed. Using only the informed rater provides a very adequate picture of severity and patterns of psychopathology on a cross-sectional basis.

Hyperparathyroidism but a negative sestamibi scan: a clinical dilemma.

BACKGROUND: The outcomes of patients with biochemically confirmed hyperparathyroidism but a negative Tc-99 Sestamibi scan are unclear. We examined the outcomes and quality of life of patients having surgery and those who had medical therapy. METHODS: Patients having a diagnosis of hyperparathyroidism with confirmed elevated calcium and parathormone levels, yet negative sestamibi scans were identified. The RAND SF-36 Health Survey was administered via mail to these patients. The patient's charts were then reviewed to verify treatments and to determine outcomes. RESULTS: Ninety-five patients fitting the criteria were identified. Twenty patients completed all aspects of the study. Ten of the respondents had undergone parathyroidectomy, and 10 had not. The surgical patients scored more favorably in all 8 of the measured parameters than patients treated medically. The differences in 3 domains, physical functioning, pain, and social functioning, were statistically significant. CONCLUSIONS: Our findings suggest that surgical therapy confers a better quality of life and is superior to medical therapy in the treatment of primary hyperparathyroidism, even in patients having a negative sestamibi scan.

Responsiveness and clinically important differences for the WOMAC and SF-36 after hip joint replacement.

OBJECTIVES: To study responsiveness and establish the minimal clinically important differences (MCID) and minimal detectable change (MDC) in patients undergoing total hip replacement (THR) using the Short Form 36 (SF-36) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). METHODS: We conducted a prospective observational study in three public hospitals of all consecutive patients with a diagnosis of hip osteoarthritis (OA) on waiting lists to undergo THR. Patients completed the SF-36 and the WOMAC (subscales transformed to 0 to 100), which measured the health-related quality of life (HRQoL), before intervention and 6 months and 2 years later, and additional transitional questions, which measured the changes in the joint 6 months postoperatively. RESULTS: Improvements at 6 months after a THR were between 37 (stiffness) and 39 points (pain), depending on the WOMAC domain. The SF-36 domains also showed improvements: physical function (31.91), physical role (33.71), and bodily pain (29.77). From 6 months to 2 years, improvements ranged from 2 to 5 points, except for role physical (13.25). A ceiling effect was detected on some WOMAC domains as well as a floor effect on the SF-36. The MCID ranged from 25.91 (stiffness) to 29.26 (pain) on the WOMAC and from 10.78 (physical role) to 20.40 (physical function) on the SF-36. The MDC ranged from 21.38 (pain) to 27.98 (stiffness) on the WOMAC and from 18.99 (physical function) to 42.05 (social function) on the SF-36. CONCLUSIONS: These values indicate expected gains after THR. However, the MCID and MDC values must be viewed cautiously due to the uncertainty of these estimators and should not be considered as absolute thresholds.

Responsiveness and clinically important differences for the WOMAC and SF-36 after total knee replacement.

OBJECTIVES: To study responsiveness and establish the minimal clinically important differences (MCIDs) and minimal detectable change (MDC) in patients undergoing total knee replacement (TKR) using the Short Form 36 (SF-36) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). METHODS: Prospective observational study in three public hospitals of all consecutive patients on waiting lists to undergo TKR intervention with diagnosis of knee osteoarthritis (OA). Patients were asked to complete before the intervention and at 6 months and 2 years afterward the SF-36 and the WOMAC health-related quality of life questionnaires (HRQoL), and additional transition questions which measured the changes in their joint at 6 months. In both questionnaires the possible range of values is from 0 to 100 points. RESULTS: In WOMAC improvement at 6 months after a TKR was between 27 (stiffness) and 31 points (pain). The SF-36 showed improvements between the 28.3 points of role physical and 2.79 of general health. From 6 months to 2 years, WOMAC improvements were between 2 and 6 points. The MCID ranged from 14.52 (stiffness) to 22.87 (pain) on the WOMAC and in the physical domains of SF-36 from 11.56 (physical function) to 16.86 (bodily pain). On the WOMAC, the MDC ranged from 13.11 (function) to 29.12 (stiffness), and on SF-36 from 19.50 (physical function) to 41.23 (social functioning). CONCLUSIONS: The MCID for TKR is around 15 on WOMAC, while with the SF-36 of at least 10 points. These values should not be considered as absolute thresholds.
