Patterns of subjective quality of life among older adults in rural Vietnam and Indonesia

Aim: This paper aims to assess the subjective quality of life (SQOL) and its correlates among older adults in rural communities of Vietnam and Indonesia. Methods: The paper uses the data from the INDEPTH/WHO Study on global aging and adult health (SAGE). The study was carried out in the FilaBavi Health and Demographic Surveillance System (HDSS) site in Vietnam and in Purworejo HDSS in Indonesia. All people aged 50 years and over who lived in these two HDSS areas were surveyed. Face‐to‐face household interviews were carried out by trained surveyors using the standardized summary version of the INDEPTH/WHO SAGE questionnaire. The SQOL was assessed by asking the respondents “How would you rate your overall quality of life?” The response set was a five‐point scale where 1 = Very good, 2 = Good, 3 = Moderate, 4 = Bad, 5 = Very bad. Results: In both countries, the SQOL was reported to be higher among (i) men; (ii) people with higher education; (iii) people who were in a marital partnership; (iv) people who lived with other family members; and (v) those with higher economic status, compared with that in those of other category(ies) of the same characteristic. In Vietnam, people who belonged to the second to fifth economic quintiles and had more than 6 years of education were sevenfold more likely to report very good/good quality of life compared with those who belonged to the first economic quintile (poorest) and had no formal education. The corresponding figure was 2.7 for Indonesia. Conclusions: The patterns of sociodemographic determinants of SQOL show that inequality in quality of life exists among older adults in the two study settings.

Long-term Prostate-specific Antigen Velocity in Improved Classification of Prostate Cancer Risk and Mortality

Background

It remains unclear whether adding long-term prostate-specific antigen velocity (PSAV) to baseline PSA values improves classification of prostate cancer (PCa) risk and mortality in the general population.

Objective

To determine whether long-term PSAV improves classification of PCa risk and mortality in the general population.

Design, setting, and participants

We studied 503 men aged 30–80 yr, with and without PCa, who had repeated PSA measurements over 20 yr and up to 28 yr before PCa diagnosis. These were selected from among 7455 men in the Copenhagen City Heart Study, a prospective, general population study with follow-up from 1981 through 2010. Results were subsequently applied to all 1 351 441 men aged 40–80 yr living in Denmark from 1997 through 2006.

Outcome measurements and statistical analysis

PCa risk and mortality were assessed using Cox regression. Improvement in risk classification was assessed using the net reclassification index (NRI).

Results

Age-adjusted hazard ratios for PCa risk and mortality were 2.7–5.3 and 2.3–3.4, respectively, for long-term PSAV when added to models already including baseline PSA values. For PCa risk and mortality, adding long-term PSAV to models already including baseline PSA values and age yielded continuous NRIs of 98–99% and 56–106%, respectively. Used on a nationwide scale (eg, for men aged 60–64 yr), long-term PSAV >0.35 versus ≤0.35 ng/ml per year appropriately reclassified 128 of 10 000 men with PCa and 8095 of 10 000 men with no PCa. Correspondingly, inappropriately reclassified were 49 of 10 000 men with PCa and 1658 of 10 000 men with no PCa.

Conclusions

Long-term PSAV in addition to baseline PSA value improves classification of PCa risk and mortality. Applying long-term PSAV nationwide, the ratio of appropriately to inappropriately classified men would typically be 5:1.     

The Copeland resurfacing humeral head implant does not restore humeral head anatomy. A retrospective study

Purpose

Recently, there has been concern that the Copeland resurfacing humeral head implant (RHHI) leaves the shoulder joint overstuffed. The purpose of this study was in a selected cohort of patients operated with a Copeland RHHI (1) to evaluate the Length of the Gleno-Humeral Offset (LGHO), (2) to assess the patient-reported quality of life and functional outcome measured by Western Ontario Osteoarthritis of the Shoulder Index (WOOS) and (3) to determine the number of revisions in the cohort.

Methods

Pre- and postoperative radiographs were retrieved from 71 of 91 possible patients operated with a Copeland RHHI from 2005 to 2009. The cohort consisted of 30 males and 41 females at a mean age of 61 (38–89) years. One radiologist measured the LGHO and performed double measurements. The WOOS score 1 year after surgery and the number of revisions from all patients operated with a Copeland RHHI in Denmark was requested from the Danish Shoulder Arthroplasty Registry.

Results

The mean LGHO was 4.99 ± 0.53 cm before surgery and 5.39 ± 0.58 cm after surgery, (p < 0.001). 95 % limits of agreement for measurements of LGHO were ± 0.11 cm. One year after surgery, the WOOS score was 67 for the cohort and 64 for all patients operated with a Copeland RHHI in Denmark. 13 of 71 RHHI in the cohort were revised.

Conclusion

The Copeland RHHI causes significantly increased LGHO and leads to overstuffing in the shoulder joint. The WOOS score in the cohort was comparable to that for all other Danish patients operated with a Copeland RHHI.     

Survey of Use of the Insufflator-Exsufflator in Patients With Spinal Cord injury

Abstract

Background/Objective: The insufflator-exsufflator has been shown to be effective in assisting cough in individuals with spinal cord injury. However, many institutions do not use this device. The study was performed to assess use of the device and attitudes among health care providers.

Methods: We developed a questionnaire with 4 categories of questions: knowledge of the device, type of facility, clinical practice with the device, and patient and provider satisfaction. The questionnaire was mailed to members of the American Paraplegia Society.

Results: Eighty-six questionnaires (16%) were returned. The device was being used in 49% of the institutions. The device was most commonly used with a tracheostomy; use did not correlate with size or type of facility. Patient and provider satisfaction with the insufflator-exsufflator was high.

Conclusions: The insufflator-exsufflator is used as a means of removal of secretions in approximately one half of institutions polled. Satisfaction with the device is high.     

Low perfusion pressure during CPB may induce cerebral metabolic and ultrastructural changes

Background. Recently we reported on cerebral metabolic changes suggesting ischemia in piglets during nitroprusside-induced low-pressure CPB. We here investigated whether a mean arterial pressure (MAP) of 40–45 mmHg could provoke similar changes by a NO-independent intervention. Methods. Piglets underwent 60 minutes normothermic followed by 90 minutes hypothermic CPB. The LP-group (n=8) had MAP of 40–45 mmHg by phentolamine while the HP-group (n=8) had MAP of 60–80 mmHg by norepinephrine. Cerebral glucose, lactate, pyruvate and glycerol were determined. In the last two animals of each group, cerebral tissue was examined by electron microscopy. Results. Cerebral lactate was higher in the LP-group than the HP-group during normothermic CPB. Compared with baseline, cerebral glucose of the LP-group decreased whereas lactate/pyruvate-ratio, lactate and glycerol-concentrations increased during normothermic CPB. In the HP-group these parameters remained unchanged. Electron microscopy showed 31.2% and 8.3% altered mitochondria in the cortical micrographs taken from the LP- and the HP-group, respectively (p<0.001). Conclusion. MAP below 45 mmHg during CPB was associated with cerebral biochemical and morphological changes consistent with anaerobic metabolism and subcellular injury.     

Repeated image analyses improves accuracy in assessing arterial flow-mediated dilatation

Objectives. A high degree of variability has been reported regarding the ultrasound-based assessment of flow-mediated dilatation. We wanted to investigate the variability and find out how it might be reduced most efficiently. Design. Brachial artery flow-mediated dilatation was measured by high-resolution ultrasound in 22 healthy adults on two consecutive days. Two observers analysed all images twice. The total variance was split into variance components and estimated hierarchically using the method of restricted maximum likelihood. Results. The relative proportional contributions from intraobserver (residual), interobserver, interpatient and interday variance components, with percentage dilatation as outcome variable, were 0.41, 0.18, 0.25, and 0.15, respectively. Conclusions. The major source of variability when assessing flow-mediated dilatation was found to be intraobserver variability. The simplest way to reduce total variability is for the observer to average results from repeated image analyses. We suggest that three repetitions are sufficient. This will reduce the total variance by 30%.     

Missed isolated volar dislocation of the scaphoid

A patient presented with volar dislocation of the scaphoid, the diagnosis of which had been missed for two weeks. He was treated with open reduction through a combined volar and dorsal approach with decompression of the median nerve, internal fixation, and a cast for eight weeks. One year postoperatively the functional result was good. A radiograph showed no sign of avascular necrosis.     

Development and validation of the Affective Self Rating Scale for manic,depressive, and mixed affective states

Most rating scales for affective disorders measure either depressive or hypomanic/manic symptoms and there are few scales for hypomania/mania in a self-rating format. We wanted to develop and validate a self-rating scale for comprehensive assessment of depressive, manic/hypomanic and mixed affective states. We developed an 18-item self-rating scale starting with the DSM-IV criteria for depression and mania, with subscales for depression and mania. The scale was evaluated on 61 patients with a diagnosis of affective disorder, predominantly bipolar disorder type I, using Montgomery–Åsberg Depression Rating Scale (MADRS), Hypomania Interview Guide—Clinical version (HIGH-C) and Clinical Global Impression scale, modified for bipolar patients (CGI-BP) as reference scales. Internal consistency of the scale measured by Cronbach's alpha was 0.89 for the depression subscale and 0.91 for the mania subscale. Spearman's correlation coefficients (two-tailed) between the depression subscale and MADRS was 0.74 (P<0.01) and between mania subscale and HIGH-C 0.80 (P<0.01). A rotated factor analysis of the scale supported the separation of symptoms in the mania and depression subscale. We established that the self-rating scales sensitivity to identify mixed states, with combined cut-offs on the MADRS and HIGH-C as reference, was 0.90 with a specificity of 0.71. The study shows that the Affective Self Rating Scale is highly correlated with ratings of established interview scales for depression and mania and that it may aid the detection of mixed affective states.
