MMP8 increases tongue carcinoma cell-cell adhesion and diminishes migration via cleavage of anti-adhesive FXYD5

Matrix metalloproteinases (MMPs) modify bioactive factors via selective processing or degradation resulting in tumour-promoting or tumour-suppressive effects, such as those by MMP8 in various cancers. We mapped the substrates of MMP8 to elucidate its previously shown tumour-protective role in oral tongue squamous cell carcinoma (OTSCC). MMP8 overexpressing (+) HSC-3 cells, previously demonstrated to have reduced migration and invasion, showed enhanced cell-cell adhesion. By analysing the secretomes of MMP8 + and control cells with terminal amine isotopic labelling of substrates (TAILS) coupled with liquid chromatography and tandem mass spectrometry (LC-MS/MS), we identified 36 potential substrates of MMP8, including FXYD domain-containing ion transport regulator 5 (FXYD5). An anti-adhesive glycoprotein FXYD5 has been previously shown to predict poor survival in OTSCC. Cleavage of FXYD5 by MMP8 was confirmed using recombinant proteins. Furthermore, we detected a loss of FXYD5 levels on cell membrane of MMP8 + cells, which was rescued by inhibition of the proteolytic activity of MMP8. Silencing (si) FXYD5 increased the cell-cell adhesion of control but not that of MMP8 + cells. siFXYD5 diminished the viability and motility of HSC-3 cells independent of MMP8 and similar effects were seen in another tongue cancer cell line, SCC-25. FXYD5 is a novel substrate of MMP8 and reducing FXYD5 levels either with siRNA or cleavage by MMP8 increases cell adhesion leading to reduced motility. FXYD5 being a known prognostic factor in OTSCC, our findings strengthen its potential as a therapeutic target.

Insufficient Sleep Is Associated with Obesity and Excessive Screen Time Amongst Ten-Year-Old Children in Sweden

PURPOSE

This study investigated sleep, television, computer habits, and obesity in school-age children.

DESIGN AND METHODS

This was a cross-sectional self-report survey of 1260 children in grade 4 (mean age, 10.1) living in southern Sweden (49.1% boys). The heights and weights of 1097 (87.1%) of the children were recorded. Descriptive statistics, bivariate analyses, and multiple logistic regression were employed.

RESULTS

The median length of self-reported sleep on weeknights was 9.5h. Approximately 40% of the children reported receiving <9h of sleep. The median bedtime was 9PM (21:00). On weekends, the median bedtime was 1 h later, and they delayed getting up by 1.5h. The median time spent watching TV and using a computer was 1 h each. The prevalence of being overweight (including obesity) was 18%. Insufficient sleep (<9h) was associated with being overweight, watching TV, or using a computer for two or more hours each day, difficulty falling asleep, and being tired at school.

CONCLUSIONS

School-age children who receive less sleep are more likely to be overweight and report excessive television and computer use. A strong and urgent need exists to highlight the importance of healthy sleep and media habits. It is challenging for pediatric nurses and school nurses to teach children and their families about healthy sleep and media habits.

Effects of Femoral Arteriography and Low Osmolar Contrast Agents on Renal Function

The contrast media-induced renal effects of 3 different low osmolar contrast agents were prospectively evaluated with creatinine, beta-2-microglobulin, and urea in serum before and after femoral arteriography in 110 consecutive patients. Forty-two patients (38%) had at least one of the 2 major risk factors for contrast media-induced nephropathy; diabetes mellitus or renal dysfunction. Six patients (5%) had both risk factors. There were statistically significant increases of S-creatinine (6.5%, p < 0.001) and S-beta-2-microglobulin (7.4%, p < 0.001) but no increase of S-urea, in the total patient material. This effect was independent of preexaminatory renal function, the presence of diabetes mellitus and type of low osmolar contrast agent used in these patients who were properly hydrated before the examination. The amount of administered contrast medium did not correlate with the degree of contrast agent-induced renal function impairment.

Comparison of Iopromide versus Iohexol in Aortobifemoral Arteriography

A double-blind randomized, clinical trial was conducted in 9 hospitals comparing the use of non-ionic contrast media (CM) iopromide 300 (Ultravist) and iohexol 300 (Omnipaque) during peripheral arteriography in a total of 446 patients. After premedication with morphine-scopolamine each patient was given two consecutive injections of 50 ml CM at a rate of 12 ml/s above the aortic bifurcation. Both CM were well tolerated. There were no differences between the two substances as far as general tolerance, pulse rate, blood pressure, sensation of heat or pain after CM injection were concerned.

Reconstructive vascular surgery and the extent of tissue damage due to diabetic foot ulcers relates to risk of new ulceration in patients with PAD

OBJECTIVE

There is limited information regarding new ulceration following the healing of ischaemic foot ulcers in diabetic patients. Our aim is to study new ulcerations in the same foot as the previous ulcer(s) in patients with diabetes and severe peripheral artery disease (PAD).

METHOD

Patients with diabetes and severe PAD who healed from previous ulcer(s) (Wagner grade 1-5, at or below the ankle), were recruited for the prospective study from the time of healing of their ulcer. Patients were followed up regarding new ulceration, and their treatments and ulcer status noted either directly or on examination of medical records.

RESULTS

We analysed the data on 602 patients with diabetes and severe PAD with healed foot ulcers, either primarily (n=443, 74%) or after minor amputation (n=159, 26%). Of these 51% (n=305) had revascularisation before healing from the previous ulcer, 34% (n=202) developed a new ulcer on the same foot within 15 months (range 0-106). Amputation was required by 22% (n=45) of patients, with a new ulcer on the same foot. The median survival time of all patients (n=602) was 54 months. By regression analysis, a low maximal Wagner grade for the previous ulcer and reconstructive vascular surgery was related to a decreased risk of developing new ulcers in the same foot.

CONCLUSION

Patients with diabetes and ischaemic foot ulcers have a high-risk for developing new ulcers and amputation in the same foot after healing. The extent of tissue involvement in the previous ulcer and reconstructive vascular surgery affected the risk for development of new ulcers.

Assessment of hypertensive patients' self-care agency after counseling training of nurses

PURPOSE

The aim of the study was to assess hypertensive patients' self-care agency and any correlation with the patient's lifestyle changes and the nurse's degree of patient centeredness after counseling training.

DATA SOURCES

Nurses in the intervention group (IG; n = 19) working at nurse-led clinics at health centers were trained in patient centeredness (motivational interviewing) and the stages of change model and included 137 patients. Nurses in the control group (CG; n = 14) included 51 patients. The Exercise of Self-Care Agency (ESCA) instrument was used. There was a significant difference from baseline to the 2-year follow-up in the ESCA score (IG, p = .0001). An increase in ESCA score was correlated with an increased level of physical activity after 2 years (IG, p = .0001; CG, p = .040).

CONCLUSIONS

The counseling training gave an increase in the patients' self-care agency scores, which was significantly correlated with increased physical activity.

IMPLICATIONS FOR PRACTICE

In clinical practice it is important for nurses to be patient centered in their counseling to affect patients' self-care agency in a positive direction.

Early revascularization after admittance to a diabetic foot center affects the healing probability of ischemic foot ulcer in patients with diabetes

OBJECTIVES

There is limited information about whether time from recognition of decreased perfusion to revascularization affects the probability of healing in a patient with a diabetic foot ulcer. The aim of the present study was to examine whether time to revascularization after referral to a multidisciplinary foot center was related to the outcome of foot ulcers in patients with diabetes and severe peripheral arterial disease (PAD).

METHODS

Patients with diabetes, a foot ulcer, and a systolic toe pressure <45 mmHg or an ankle pressure <80 mmHg were prospectively included at the foot center, and considered for revascularization according to a preset protocol. All patients underwent invasive revascularization, either percutaneous transluminal angioplasty (PTA) or reconstructive vascular surgery. All patients had continuous follow-up until healing or death irrespective of the type of revascularization.

RESULTS

A total of 478 patients were included (age 74 [range 66-80] years, 60% males), of whom 315 patients (66%) had PTA, and 163 (34%) had reconstructive surgery. Of the 478 patients, 217 (45%) healed primarily, 88 (19%) healed after a minor amputation, 76 (16%) healed after a major amputation and 92 patients (19%) died unhealed. The median time from inclusion in the study to revascularization was 8 weeks (3-18 weeks). Time to vascular intervention within 8 weeks (p < .001), maximum Wagner grade reached <3 (p < .001), absence of peripheral edema (p = .033), and presence of intermittent claudication (p = .001) were related to a higher probability of healing.

CONCLUSIONS

Time to revascularization and extent of tissue damage were related to the probability of healing of ischemic foot ulcer in patients with diabetes over time. In the presence of a decreased perfusion in a patient with diabetes and a foot ulcer not only revascularization per se but also timing of revascularization is important for the possibility of healing without a major amputation.

Effects on hypertensive patients' satisfaction with information about their medication after nurses' consultation training

Background

There is a well-known problem in hypertension care with patients’ adherence to treatment. Patients who score high in answering the instrument Satisfaction with Information about Medicine Scale are reported to have greater adherence to their medication.

Aim

To explore how hypertensive patients’ satisfaction with information about their medicines was affected by nurses’ education in Motivational Interviewing.

Material and methods

The Stages of Change model and Motivational Interviewing was the theoretical base for consultation training for nurses. Nineteen nurses attended 3 days of video-recorded consultation training with simulated patients. They were updated in hypertensive medication and were trained in motivating patients to improve their self-management as well as adherence to lifestyle changes and medication. The satisfaction with information instrument identifies patients’ satisfaction with information about the action and usage of medication as well as potential problems with it. The instrument was used to assess how well the needs of individual patients for medicine information were met at baseline and 2 years after the training. The 19 trained nurses in the intervention group worked with 137 patients, and a control group of 16 nurses, who gave normal care, worked with 51 patients.

Results

There was a difference between the intervention and control group in total score (P=0.028) 2 years after the intervention. Patients in the intervention group perceived higher satisfaction with the action and usage of their medication (P=0.001) and a lower degree of potential problems with their medication (P=0.001). Patients in the control group also perceived a lower degree of potential problems with their medication (P=0.028).

Conclusion

We suggest that consultation training for nurses with the aim of motivating patients to be more self-directed in their self-care improves satisfaction with information about medication.

Overweight and television and computer habits in Swedish school-age children and adolescents: a cross-sectional study

The aim of this cross-sectional study was to investigate the prevalence of overweight and obesity in children and adolescents (6-16 years), and relationships between being overweight and sleep, experiencing of fatigue, enjoyment of school, and time spent in watching television and in sitting at the computer. Trained school nurses measured the weight and height of 2891 children aged 6, 7, 10, 14, and 16, and distributed a questionnaire to them regarding television and computer habits, sleep, and enjoyment of school. Overweight, obesity included, was present in 16.1% of the study population. Relationships between lifestyle factors and overweight were studied using multivariate logistic regression analysis. Having a bedroom television and spending more than 2 h a day watching television were found to be associated with overweight (OR 1.26 and 1.55 respectively). No association was found between overweight and time spent at the computer, short sleep duration, enjoyment of school, tiredness at school, or difficulties in sleeping and waking up. It is recommended that the school health service discuss with pupils their media habits so as to promote their maintaining a healthy lifestyle.

Sleep and television and computer habits of Swedish school-age children

The aim of this study was to investigate sleep, television and computer habits and enjoyment and feelings of tiredness in school of school-age children and adolescents in Sweden. An instrument found to be valid and reliable here was distributed to 3,011 children aged 6, 7, 10, 14, and 16 years. Those sleeping less than the median length of time reported a significantly lower degree of enjoyment of school. Short sleep was found to be associated with having a bedroom TV, spending more than 2 hr a day at the TV or the computer, being tired in school, and having difficulties both in waking up and in sleeping. Discussing sleep and media habits with schoolchildren and their parents regarding matters of optimal sleep and of how media habits affect sleep and learning is seen to be an important task of the school health service.

Transmitter deficits in Alzheimer's disease

The pattern of neurotransmitter pathway losses in Alzheimer's disease are reviewed. Deficits of the cholinergic pathway from the nucleus basalis, the noradrenergic pathway from the locus coeruleus and the serotoninergic pathway from the raphe nuclei are established. Cortical somatostatin interneurons are affected and dopaminergic neurons may be affected although these may be late or secondary phenomena in the disease process. Other neuronal systems, particularly in the hippocampus and temporal cortex, are also damaged. However, the disease is not one of generalised neuronal atrophy since some neurons are selectively spared. The established pathway-specific losses are discussed in relation to the clinical symptomatology and the pathology of the disorder. The biochemical and histological findings are compared with similar measurements made on tissues from other dementing disorders in an attempt to trace features common to dementias. Finally, as an addendum, a hypothesis is briefly outlined which attempts to explain the common features of the affected neurons and the pathogenesis of the disorder.

Driving to Learn in a Powered Wheelchair: The Process of Learning Joystick Use in People With Profound Cognitive Disabilities

The Driving to Learn project explored ways to help people with profound cognitive disabilities practice operating a joystick-operated powered wheelchair. The project used a grounded theory approach with constant comparative analysis and was carried out over 12 yr. The participants were 45 children and adults with profound cognitive disabilities. Reference groups included 17 typically developing infants and 64 participants with lesser degrees of cognitive disability. The data sources included video recordings, field notes, open interviews, and a rich mixture of literature. The findings that emerged yielded strategies for facilitating achievements, an 8-phase learning process, an assessment tool, and a grounded theory of deplateauing explaining the properties necessary for participants to exceed expected limitations and plateaus. Eight participants with profound cognitive disabilities reached goal-directed driving or higher. Participants were empowered by attaining increased control over tool use, improving their autonomy and quality of life.

Development and psychometric evaluation of a new instrument for measuring sleep length and television and computer habits of Swedish school-age children

The aim was to develop a new instrument for measuring length of sleep as well as television and computer habits in school-age children. A questionnaire was constructed for use when children visit the school health care unit. Three aspects of the validity of the questionnaire were examined: its face validity, content validity, and construct validity. Test-retest reliability was assessed by giving the questionnaire twice, 2 weeks apart, to the respondents. The questionnaire was assessed as being reasonably valid, the test-retest results (n = 138) showing 90.4% of the estimates regarding bedtime on weeknights on the two survey occasions to lie within ± 30 min of each other, the test-retest agreement also being rather close (κ > .600) regarding both sleep and media habits. The instrument can be a valuable tool in a clinical setting, both for measuring sleep habits in a class and for discussing sleep with individual school children and their families.

Factors related to outcome of neuroischemic/ischemic foot ulcer in diabetic patients

OBJECTIVES

Peripheral vascular disease (PVD) is an important limiting factor for healing in neuroischemic or ischemic diabetic foot ulcer. The purpose of this study was to identify factors related to healing in patients with diabetes with foot ulcers and severe PVD.

METHODS

Patients with diabetes with a foot ulcer, consecutively presenting at a multidisciplinary foot center with a systolic toe pressure <45 mm Hg or an ankle pressure <80 mm Hg were prospectively included, followed according to a preset program, and with the exception of specified exclusions, subjected to angiography offered vascular intervention when applicable. All patients had continuous follow-up until healing or death irrespective of the type of vascular intervention.

RESULTS

One thousand one hundred fifty-one patients were included. Eighty-two percent had a toe pressure <45 mm Hg and 49% had an ankle pressure <80 mm Hg. Eight hundred one patients (70%) underwent an angiography. Out of these, 63% had vascular intervention, either percutaneous transluminal angioplasty (PTA; 39%) or reconstructive surgery (24%). Nine percent of the patients had one or more complications after angiography. PTA was multisegmental in 46% and to the crural arteries in 46%. Reconstructive surgery was distal in 51%. Age (P < .001), renal function impairment (P = .005), congestive heart failure (P = .01), number and type of ulcer (P < .001), and severity of PVD (P = .003) affected the outcome of ulcers. PTA and reconstructive vascular surgery increased the probability of healing without amputation (odds ratio [OR], 1.77 and 2.05, respectively).

CONCLUSION

Probability of ulcer healing is strongly related to comorbidity, extent of tissue involvement, and severity of PVD in patients with diabetes with severe PVD.

Predicting mortality of residents at admission to nursing home: a longitudinal cohort study

Background

An increasing numbers of deaths occur in nursing homes. Knowledge of the course of development over the years in death rates and predictors of mortality is important for officials responsible for organizing care to be able to ensure that staff is knowledgeable in the areas of care needed. The aim of this study was to investigate the time from residents' admission to Icelandic nursing homes to death and the predictive power of demographic variables, health status (health stability, pain, depression and cognitive performance) and functional profile (ADL and social engagement) for 3-year mortality in yearly cohorts from 1996-2006.

Methods

The samples consisted of residents (N = 2206) admitted to nursing homes in Iceland in 1996-2006, who were assessed once at baseline with a Minimum Data Set (MDS) within 90 days of their admittance to the nursing home. The follow-up time for survival of each cohort was 36 months from admission. Based on Kaplan-Meier analysis (log rank test) and non-parametric correlation analyses (Spearman's rho), variables associated with survival time with a p-value < 0.05 were entered into a multivariate Cox regression model.

Results

The median survival time was 31 months, and no significant difference was detected in the mortality rate between cohorts. Age, gender (HR 1.52), place admitted from (HR 1.27), ADL functioning (HR 1.33-1.80), health stability (HR 1.61-16.12) and ability to engage in social activities (HR 1.51-1.65) were significant predictors of mortality. A total of 28.8% of residents died within a year, 43.4% within two years and 53.1% of the residents died within 3 years.

Conclusion

It is noteworthy that despite financial constraints, the mortality rate did not change over the study period. Health stability was a strong predictor of mortality, in addition to ADL performance. Considering these variables is thus valuable when deciding on the type of service an elderly person needs. The mortality rate showed that more than 50% died within 3 years, and almost a third of the residents may have needed palliative care within a year of admission. Considering the short survival time from admission, it seems relevant that staff is trained in providing palliative care as much as restorative care.

Interpretation of response categories in patient-reported rating scales: a controlled study among people with Parkinson's disease

BACKGROUND

Unambiguous interpretation of ordered rating scale response categories requires distinct meanings of category labels. Also, summation of item responses into total scores assumes equal intervals between categories. While studies have identified problems with rating scale response category functioning there is a paucity of empirical studies regarding how respondents interpret response categories. We investigated the interpretation of commonly used rating scale response categories and attempted to identify distinct and roughly equally spaced response categories for patient-reported rating scales in Parkinson's disease (PD) and age-matched control subjects.

METHODS

Twenty-one rating scale response categories representing frequency, intensity and level of agreement were presented in random order to 51 people with PD (36 men; mean age, 66 years) and 36 age-matched controls (14 men; mean age, 66). Respondents indicated their interpretation of each category on 100-mm visual analog scales (VAS) anchored by Never--Always, Not at all--Extremely, and Totally disagree--Completely agree. VAS values were compared between groups, and response categories with mean values and non-overlapping 95% CIs corresponding to equally spaced locations on the VAS line were sought to identify the best options for three-, four-, five-, and six-category scales.

RESULTS

VAS values did not differ between the PD and control samples (P = 0.286) or according to educational level (P = 0.220), age (P = 0.220), self-reported physical functioning (P = 0.501) and mental health (P = 0.238), or (for the PD sample) PD duration (P = 0.213) or presence of dyskinesias (P = 0.212). Attempts to identify roughly equally spaced response categories for three-, four-, five-, and six-category scales were unsuccessful, as the 95% CIs of one or several of the identified response categories failed to include the criterion values for equal distances.

CONCLUSIONS

This study offers an evidence base for selecting more interpretable patient-reported rating scale response categories. However, problems associated with raw rating scale data, primarily related to their ordinal structure also became apparent. This argues for the application of methodologies such as Rasch measurement. Rating scale response categories need to be treated with rigour in the construction and analysis of rating scales.

Toll-like receptor 9 ligands enhance mesenchymal stem cell invasion and expression of matrix metalloprotease-13

Human mesenchymal stem cells (hMSCs) are multipotent cells that are found in the bone marrow. Inflammation and tissue damage mobilize MSCs and induce their migration towards the damaged site through mechanisms that are not well defined. Toll-like receptor-9 (TLR9) is a cellular receptor for microbial and vertebrate DNA. Stimulation of TLR9 induces inflammatory and invasive responses in TLR9-expressing cells. We studied here the expression of TLR9 in human MSCs and the effects of synthetic TLR9-agonists on their invasion. Constitutive expression of TLR9 was detected in human MSCs but the expression was suppressed when MSCs were induced to differentiate into osteoblasts. Using standard invasion assays and a novel organotypic culture model based on human myoma tissue, we discovered that stimulation with the TLR9 agonistic, CpG oligonucleotides increased the invasion capacity of undifferentiated MSCs. Simultaneously, an increase in MMP-13 synthesis and activity was detected in the CpG-activated MSCs. Addition of anti-MMP-13 antibody significantly diminished the CpG-induced hMSC invasion. We conclude that treatment with TLR9-ligands increases MSC invasiveness, and this process is at least partially MMP-13-mediated.

Symptoms, care needs and diagnosis in palliative cancer patients in acute care hospitals: a 5-year follow-up survey

INTRODUCTION

Palliative cancer care in acute hospitals is scarcely studied. We therefore described and compared symptoms, care needs and types of cancer sites in 2002 compared to 2007 and analysed the relationships between these factors.

METHODS

The study was population-based with a cross-sectional design and was carried out in medical, surgical and oncology wards in two acute care hospitals with no advanced palliative home care service. In 2002, 82 one-day-inventories were done (1 352 patients) compared to 142 one-day-inventories in 2007 (2 972 patients). Symptoms, care needs and cancer site were registered according to a questionnaire. Multiple logistic regression models were used to analyse associations between symptoms, care needs and cancer site.

RESULTS

The proportion of palliative cancer patients had decreased during a five year period (14% vs. 11%, p<0.01). The patients were older in 2007 (74 vs. 70 years, p<0.001) and had more symptoms and care needs per patient (2.6 vs. 1.6, p<0.001). The most common symptoms were pain and deterioration and the most common cancer sites were prostate and colorectal cancer in both samples. Associations between symptoms, care needs and cancer site were mostly weak. Deterioration was associated with colorectal cancer, whereas pain was not associated with any specific cancer site. In haematological malignancies there was a high occurrence of infections and a high need of blood transfusions and infusions. Stomach/oesophagus cancers were significantly associated with nausea, nutritional problems and need of infusions while unknown primary malignancies were associated with abdominal surgery and infusions.

DISCUSSION

Although we do not know all the causes for hospitalization, this study indicates that more focus should be on the symptoms instead of the specific cancer diagnosis. The findings also indicate that many palliative cancer patients' problems would be suitable for advanced palliative home care instead of acute hospital care.

Parents' worried state of mind when fetal ultrasound shows an unexpected finding: a comparative study

OBJECTIVE

Most parents yearn for a second-trimester ultrasound examination and feel excitement about it, but some also worry about what the examination will show. According to prior research, using only generic instruments or specific questionnaires, anxiety decreases when the ultrasound findings are normal. The aim of this study was to compare parents' worry (Parents' Expectations, Experiences, and Reactions to Ultrasound [PEER-U] State of Mind Index) and sense of coherence before and after a routine second-trimester ultrasound examination when it showed normal or abnormal findings.

METHODS

A 1-year cohort study was performed at a Swedish university hospital. A total of 2049 parents who had their second-trimester ultrasound examinations there filled in a questionnaire consisting of 2 parts before and after the examinations.

RESULTS

Parents with normal ultrasound findings were less worried than parents with abnormal findings. The group with normal findings also showed less worry after the examination than before. A sex analysis showed similar patterns.

CONCLUSIONS

Parents with abnormal ultrasound findings are more worried and anxious. The new instrument, the PEER-U State of Mind Index, not only measures parents' worry but can also expose what influences their ultrasound examination experience.

Could androgens protect middle-aged women from cardiovascular events? A population-based study of Swedish women: The Women's Health in the Lund Area (WHILA) Study

OBJECTIVE

The aim of this analysis was to delineate perceived associations between androgens and cardiovascular events in perimenopausal women.

DESIGN

A cross-sectional, population-based study of 6440 perimenopausal women aged 50-59 years, living in Southern Sweden. In all, 461 (7.1%) women were premenopausal (PM), 3328 (51.7%) postmenopausal without hormone therapy (HT) (PM0) and 2651 (41.2%) postmenopausal with HT (PMT). For further comparisons, 104 women (1.6%) who reported cardiovascular disease (CVD) were studied in detail; 49 had had a myocardial infarction, 49 a stroke and six women both events. For each woman with CVD, two matched controls were selected (n=208).

RESULTS

In the matched controlled series, androstenedione levels were lower (p<0.005) in cases. Cases with hormone therapy had also lower testosterone levels than matched controls (p=0.05). In the total cohort, by using multiple logistic regression analyses, testosterone was positively associated with low density lipoprotein cholesterol (p<0.001) and high density lipoprotein cholesterol (HDL-C) (p<0.001) in all women, but negatively associated with levels of triglycerides in both the PM0 (p<0.001) and PMT (p<0.001) groups. Androstenedione levels were positively associated with HDL-C (p<0.05) and negatively with triglycerides (p<0.05) in the PM group.

CONCLUSION

Women with cardiovascular disease had lower serum androgen levels, particularly women using hormone replacement therapy, even when controlled for lipids and other potential risk factors.

Whose quality of life? Ethical implications in patient-reported health outcome measurement

OBJECTIVES

Patient-reported health status questionnaires intend to assess illness and therapy from the patients' perspective. To provide fair and valid assessments, they should be equally relevant to major subsets of respondents. Furthermore, disease-specific measures are assumed to be perceived as more relevant than generic ones. This study assessed these assumptions among people with Parkinson's disease.

METHODS

Cross-sectional data from 202 people with Parkinson's disease (54% men; mean age, 70) were analyzed regarding patient-rated relevance and predictors of patient-rated poor relevance of two generic [the 36-item Short Form Health Survey (SF-36) and Nottingham Health Profile (NHP)] and one disease-specific [Parkinson's Disease Questionnaire (PDQ-39)] health status questionnaire.

RESULTS

There were no differences in relevance ratings across the questionnaires. Poorer overall quality of life [odds ratio (OR), 2.459] and mental health (OR, 1.023) were associated with poorer patient-rated relevance of the SF-36, and higher age was associated with poorer patient-rated relevance of the PDQ-39 (OR, 1.040). No significant predictors were found for the NHP.

CONCLUSIONS

The PDQ-39 failed to meet the assumption that disease-specific scales are more relevant than generic ones. Nevertheless, the most important implication of this study is an ethical one. Because the relevance of the SF-36 and PDQ-39 is perceived as poorer by those who fare least well and by older people, these scales may not reflect the perspectives of these groups. This challenges bioethical principles and threatens scientific validity. Perceived relevance of patient-centered outcomes needs to be considered, or the voice of vulnerable groups may be silenced, fair inferences prohibited, and opportunities for improved care lost.

Complexity of factors related to outcome of neuropathic and neuroischaemic/ischaemic diabetic foot ulcers: a cohort study

AIMS/HYPOTHESIS

We sought to identify factors related to short-term outcome of foot ulcers in patients with diabetes treated in a multidisciplinary system until healing was achieved.

METHODS

Consecutively presenting patients with diabetes and worst foot ulcer (Wagner grade 1-5, below ankle) (n = 2,511) were prospectively followed and treated according to a standardised protocol until healing was achieved or until death. The number of patients lost to dropout was 31. The characteristics of the remaining 2,480 patients were: 1,465 men, age 68 +/- 15 years (range 18-96), type 1 diabetes 18%, type 2 diabetes 82% and insulin-treated 62%.

RESULTS

The healing rate without major amputation in surviving patients was 90.6% (n = 1,867). Sixty-five per cent (n = 1,617) were healed primarily, 9% (n = 250) after minor amputation and 8% after major amputation; 17% (n = 420) died unhealed. Out of 2,060 surviving patients, 1,007 were neuroischaemic (48.8%). In a multiple regression analysis, primary healing was related to co-morbidity, duration of diabetes, extent of peripheral vascular disease and type of ulcer. In neuropathic ulcers, deep foot infection, site of ulcer and co-morbidity were related to amputation. Amputation in neuroischaemic ulcers was related to co-morbidity, peripheral vascular disease and type of ulcer. Age, sex, duration of diabetes, neuropathy, deformity and duration of ulcer or site of ulcer did not have an evident influence on probability of amputation.

CONCLUSIONS/INTERPRETATION

Patients with diabetic foot ulcer suffer from multi-organ disease. Factors related to outcome are correspondingly complex.

Predicting developmental deficiencies at the age of four based on data from the first seven months of life

The study examines very young children with the aim of identifying precursors of developmental problems during the first 7 months of age. Information from screening and observations in the birth clinic, in the first level of health care, and from parents was collected on five different occasions. The information that was included concerning the child and family was defined as either optimal or nonoptimal. At the age of 4 years, a clinical group was identified (11.1% of the total population). Logistic regression analyses were performed to detect risk factors. Twenty-one precursors were used to create a screening questionnaire that provided useful information (sensitivity = 56.1%, specificity = 98.8%) for predicting developmental problems of the children. The contribution of sociodemographic data was significant; medical information was less significant. The highest prediction rate surprisingly was found in the moderate clinical subgroup (62.1%), compared to the group with more severe problems that had a slightly lower rate (46.7%). The conclusion of the study is that it is possible to detect infants in need of early intervention using a continuous process of observation and screening.

Obstetric risk indicators for labour dystocia in nulliparous women: a multi-centre cohort study

BACKGROUND

In nulliparous women dystocia is the most common obstetric problem and its etiology is largely unknown. The frequency of augmentation and cesarean delivery related to dystocia is high although it is not clear if a slow progress justifies the interventions. Studies of risk factors for dystocia often do not provide diagnostic criteria for the diagnosis. The aim of the present study was to identify obstetric and clinical risk indicators of dystocia defined by strict and explicit criteria.

METHODS

A multi-centre population based cohort study with prospectively collected data from 2810 nulliparous women in term spontaneous labour with a singleton infant in cephalic presentation. Data were collected by self-administered questionnaires and clinical data-records. Logistic regression analyses were used to estimate adjusted Odds Ratios (OR) and 95% confidence intervals (CI) are given.

RESULTS

The following characteristics, present at admission to hospital, were associated with dystocia during labour (OR, 95% CI): dilatation of cervix < 4 cm (1.63, 1.38-1.92), tense cervix (1.31, 1.04-1.65), thick lower segment (1.32, 1.09-1.61), fetal head above the inter-spinal diameter (2.29, 1.80-2.92) and poor fetal head-to-cervix contact (1.83, 1.31-2.56). The use of epidural analgesia (5.65, 4.33-7.38) was also associated with dystocia.

CONCLUSION

Vaginal examinations at admission provide useful information on risk indicators for dystocia. The strongest risk indicator was use of epidural analgesia and if part of that is causal, it is of concern.

Measuring care of the elderly: psychometric testing and modification of the Time in Care instrument for measurement of care needs in nursing homes

Background

Aging entails not only a decrease in the ability to be active, but also a trend toward increased dependence to sustain basic life functions. An important aspect for appropriately elucidating the individual's care needs is the ability to measure them both simply and reliably. Since 2006 a new version of the Time in Care needs (TIC-n) instrument (19-item version) has been explored and used in one additional municipality with the same structure as the one described in an earlier study.

Methods

The TIC-n assessment was conducted on a total of 1282 care recipients. Factor analysis (principal component) was applied to explore the construct validity of the TIC-n. Cronbach's alpha was calculated to test reliability and for each of the items remaining in the instrument after factor analysis, an inter-rater comparison was carried out on all recipients in both municipalities. Independently of each other, a weighted Kappa (K_w) was calculated. Results. The mean of each weighted Kappa (K_w) for the dimensions in the two municipalities was 0.75 and 0.76, respectively. Factor analysis showed that all 19 items had a factor loading of ≥ 0.40. Three factors (General Care, Medical Care and Cognitive Care) were created.

Conclusion

The TIC-n instrument has now been tested for validity and reliability in two municipalities with satisfactory results. However, TIC-n can not yet be used as a golden standard, but it can be recommended for use of measurement of individual care needs in municipal elderly care.

Specific nasal symptoms and symptom-provoking factors may predict increased risk of developing COPD

In a 1992 questionnaire study, we found that certain nasal symptoms and symptom-provoking factors were associated with prevalence of self-reported chronic bronchitis/emphysema (CBE). In this follow-up study, we examined whether any nasal features could predict an increased incidence of self-reported physician's diagnosis of CBE/chronic obstructive pulmonary disease (COPD). In 2000, a survey was performed similar to the one in 1992. Of a paired follow-up group of 4933 participants aged 28-67 years, 4280 (86.8%) returned the questionnaire. Odds ratios (ORs) for cumulative incidence (between 1992 and 2000) of self-reported physician-diagnosed CBE/COPD and asthma, respectively, were calculated by logistic regression with adjustment for age, gender and smoking habits. Reports of thick, yellow nasal discharge and nasal blockage in 1992 predicted incidence of CBE/COPD: OR 2.3 (1.2-4.2) and 1.8 (1.1-2.8) respectively. Moreover, nasal symptoms provoked by exposure to damp/cold air and tobacco smoke predicted CBE/COPD: OR 3.4 (1.9-6.0) and 2.5 (1.4-4.2). Nasal itching and nasal symptoms provoked by exposure to grass pollen and furred animals predicted incidence of asthma. These results suggest that certain nasal symptoms and nasal symptom-provoking exposures, different from those commonly associated with asthma, may predict increased risk of developing CBE/COPD. This supports the possibility of nasal co-morbidity in COPD.

Blood pressure in middle-aged women: are androgens involved? A population-based study of Swedish women: the Women's Health in the Lund Area study

OBJECTIVE

To assess the prevalence of hypertension and use of antihypertensive drug therapy in relation to menopausal status and to delineate perceived associations between androgens and blood pressure in perimenopausal women.

METHODS

A population-based sample of women aged 50-59 (n = 6893). Women were divided into three groups according to their hormonal status: premenopausal, postmenopausal without hormone therapy, and postmenopausal with hormone therapy.

RESULT

In the premenopausal, postmenopausal without hormone therapy, and postmenopausal with hormone therapy groups, the prevalence of high blood pressure (>/= 140 mmHg systolic or >/= 90 mmHg diastolic) was 43.9, 49.9 and 45.8%, respectively. In women with normal blood pressure, adjusting for age, body mass index and smoking, there were negative associations between serum testosterone and systolic blood pressure in the total sample (P < 0.01) and the postmenopausal without hormone therapy group (P < 0.05). In women using antihypertensive drug therapy with a blood pressure of at least 140/90 mmHg, positive associations were found between serum testosterone and systolic blood pressure in the total series (P < 0.05) and in the postmenopausal without hormone therapy group (P < 0.05).

CONCLUSION

Abnormal blood pressure is common in middle-aged women regardless of hormonal status. Our findings suggest that testosterone could have a dual influence on blood pressure in perimenopausal women.

Insulin resistance and self-rated symptoms of depression in Swedish women with risk factors for diabetes: the Women's Health in the Lund Area study

Previous studies have suggested that depression increases the risk for diabetes and that this may be mediated through insulin resistance. The study aimed to analyze if self-rated symptoms of depression are related to insulin resistance among middle-aged and older Swedish women with features of the metabolic syndrome and being at risk for type 2 diabetes mellitus. We analyzed data from 1047 Swedish women aged 50 to 64 years without a history of diabetes and living in the southern part of Sweden. A variable self-rated symptoms of depression (SRSD) was defined by using the Gothenburg Quality of Life instrument. We estimated odds ratios (ORs) to determine whether or not SRSD was associated with the homeostasis model assessment of insulin resistance. The variable SRSD was not associated with insulin resistance. However, it was positively associated with waist-hip ratio (OR, 1.95; 95% confidence interval, 1.28-3.00) and negatively associated with physical exercise (OR, 1.29; 95% confidence interval, 0.99-1.68) after multivariate adjustment. In conclusion, lifestyle factors such as physical inactivity and abdominal obesity, but not insulin resistance, seem to be related to self-rated symptoms of depression in women with risk factors for diabetes mellitus. The relationship between insulin resistance and major depression needs to be further examined.

Health Hazards in Middle-Aged Women with Cardiovascular Disease: A Case-Control Study of Swedish Women. The Women's Health in the Lund Area (WHILA) Study

OBJECTIVE

To delineate the health profile in middle-aged women with cardiovascular disease (CVD).

METHODS

The Women's Health in the Lund Area (WHILA) project covered all women born 1935-1945 (n = 10,766) living in the Lund area; 6917 (64.2%) women completed a generic questionnaire and underwent physical and laboratory assessments. Of the 6917 women, 6416 were postmenopausal women, of whom 104 had CVD. For each woman with CVD, two controls were selected and matched for age, smoking habits, body mass index (BMI), waist/hip ratio (WHR), low-density lipoprotein cholesterol (LDL-C), high-density liproprotein cholesterol (HDL-C), diastolic blood pressure and hormonal status.

RESULTS

One hundred four women (1.6%) reported CVD. Forty-nine had a myocardial infarction (MI), 49 had a stroke, and 6 women had both events; 71.4% were postmenopausal, with never use of hormone therapy (HT) (PM0), and 28.6% were postmenopausal with ever use of HT (PMT). Compared with the control group, serum androstendione was lower (p = 0.004) in the case group, and menopausal estradiol (E(2)) values were less frequent (p = 0.037) in cases from the PM0 group. Among psychological and somatic symptoms, nervousness (p < 0.05), difficulty relaxing, crying easily, visual disturbance (p </= 0.01 for all), dizziness, difficulties in voiding urine, shortness of breath, breast tenderness, and constipation (p </= 0.001 for all) were more common among women with CVD. Women with CVD expressed less satisfaction with feeling healthy, body image, memory loss, irritability, and sexuality (p </= 0.05 for all). The case group had more problems with daily activities, more days spent in hospital during the previous 5 years, and more regular medical appointments with healthcare centers, more often had diabetes mellitus (DM) (p < 0.001 for all), and had experienced more falls in the previous year (p < 0.05). Urinary incontinence and decreased body weight were more common among cases (p </= 0.01 for both).

CONCLUSION

Several health hazards as well as somatic and psychological symptoms were more common in subjects with CVD, rendering them more susceptible to future disease.

Do sex hormones influence features of the metabolic syndrome in middle-aged women? A population-based study of Swedish women: the Women's Health in the Lund Area (WHILA) Study

OBJECTIVE

To outline perceived associations between various sex hormones and risk markers for cardiovascular disease in middle-aged women, with an emphasis on features of the metabolic syndrome (MS).

DESIGN

Cross-sectional analysis.

SETTING

Women's Health in the Lund Area Study.

PATIENT(S)

Population-based cohort.

INTERVENTION(S)

A generic questionnaire, physical examinations, and laboratory assessments were completed by 6,917 women aged 50-59 years living in the Lund area of southern Sweden. Women at or above defined cutoff limits for the MS were considered positively screened. After exclusion of women using hormone therapy (HT), 2,038 women with (MS+) and 2,054 women without features of the MS (MS-) were included. The ELISA techniques were used for the determination of serum androstendione (A), E2, T, sex hormone-binding globulin (SHBG), cortisol, insulin, and leptin levels. Serum lipids and lipoproteins were determined by conventional methods. Multiple linear regression analyses were performed, controlling for age, body mass index (BMI), and smoking habits.

MAIN OUTCOME MEASURE(S)

Features of the MS, sex steroids, cardiovascular risk markers.

RESULT(S)

In the MS+ group, a positive association was seen between A and systolic blood pressure. Estradiol was negatively associated with total cholesterol and diastolic blood pressure. The SHBG was negatively associated with triglycerides, blood glucose, and diastolic blood pressure and positively with high-density lipoprotein (HDL). In the MS- group, there were positive associations between A, blood glucose, and systolic blood pressure. Testosterone was positively associated with HDL. Estradiol was negatively associated with total cholesterol and positively with systolic blood pressure. The SHBG was positively associated with HDL and negatively with triglycerides and diastolic blood pressure. There were positive associations between cortisol, low-density lipoprotein (LDL) cholesterol, blood glucose, and systolic blood pressure and a negative association with triglycerides in both MS+ and MS- groups.

CONCLUSION(S)

Androstendione, E2, and T levels were associated with cardiovascular risk factors in middle-aged women. Effects by sex steroids on cardiovascular risk markers seem to be different in women with or without features of the MS.

Management of gestational diabetes from the patient's perspective ? a comparison of Swedish and Middle-Eastern born women

AIM

To explore patients' evaluation of a specialized diabetes clinic for management of women with gestational diabetes born in Sweden and the Middle East and its contribution to a decreased level of stress and improved coping capability to promote health in patients receiving care.

BACKGROUND

No studies comparing patients' perceptions of healthcare in women of different origin with gestational diabetes have been found. A perceived clinical problem in specialized diabetes care is of lower activity level in self-care in foreign- than Swedish-born women and the question is whether the healthcare organization is optimal in meeting different individuals' needs.

DESIGN

Explorative study.

METHOD

Semi-structured individual interviews by external evaluators.

PARTICIPANTS

Consecutive sample. Females with gestational diabetes, 13 born in Sweden and 14 born in the Middle East.

RESULTS

The healthcare model was perceived as functioning well. Swedish women were problem focused and information seeking. Frustration and stress were increased due to perceived delay in information concerning gestational diabetes, limited access to telephone service and lack of confidence in staff because they lacked the expected competence. Control of gestational diabetes and pregnancy by different persons led to perceived lack of holistic care. Women from the Middle East felt cared, had been given the necessary information and claimed to follow advice. Adequate information reduced respondents' anxiety and increased their control over the situation.

CONCLUSIONS

The clinic needs to be further improved by adapting programmes to persons to become problem focused by giving adequate information immediately.

RELEVANCE TO CLINICAL PRACTICE

Cultural differences in coping strategies and attitudes to gestational diabetes need to be considered. Training of staff working with gestational diabetes patients is urgently needed.

Can care of elderly be measured? A method for estimating the individual care of recipients in community health care

Background

Almost every country in the Western world has great difficulties allocating enough financial resources to meet the needs in the care of the increasing elderly population. The main problem is common to all countries and concerns the efforts to meet elderly persons' needs on an individual level while still maintaining society's responsibility for distributing justice. The aim of this study is to elaborate an instrument for measuring the quality of individual care and staff's working time in order to allocate public resources fairly. The present study gives an account of a new classification system named TiC (Time in Care), indicating how it can be used most effectively and also investigating the validity and reliability of the system.

Methods

All recipients in 13 sheltered homes for elderly care (n = 505) in a Swedish municipality were surveyed regarding the care they needed, in dimensions of General Care, Medical Care, Cognitive Dysfunction and Rehabilitation, and the time required. Construct validity was assessed by means of factor analysis. The inter-rater agreement of two raters concerning 79 recipients was measured using weighted Kappa. The stability of the instrument and its sensitivity to change were investigated through test-retest reliability measurements, conducted once a month during a six-month period. The content validity of the instrument was also assessed.

Results

Factor analysis resulted in a reduction of the number of items from 25 to 16 in three dimensions: General Care, Medical Care and Cognitive Dysfunction. The Kappa analysis showed satisfactory to excellent inter-rater agreement. The care need scores were basically stable but showed sensitivity to change in health status.

Conclusion

The instrument was found to be useful and reliable for assessing individual needs in community health care.

Does the hormonal situation modify lipid effects by lifestyle factors in middle-aged women? Results from a population-based study of Swedish women: the women's health in the Lund area study

The aim of the study was to outline whether the influence by lifestyle factors on serum lipids was modified by the hormonal situation in middle-aged women. Six thousand nine hundred eight women, aged 50 to 59 years, participated in a health assessment program, including a serum lipid profile evaluation. The women were grouped according to their hormonal status into premenopausal (PM) (n = 492), postmenopausal without hormone therapy (HT) (PM0) (n = 3600), and postmenopausal with HT (PMT) (n = 2816). From the PMT group, we analyzed oral (n = 901) and transdermal HT (n = 351) regimens, containing norethisterone acetate and 17beta-estradiol. Serum lipids and lipoproteins were determined by conventional methods. Lifestyle factors included smoking and physical activity at leisure time and at work. Multivariate linear regression analysis controlling for age, education, and dietary habits showed that current smoking was positively associated with triglycerides in the PM, PM0, PMT, and oral HT groups. In the PM0, PMT, and oral HT groups, current smoking was positively associated with total cholesterol and low-density lipoprotein and negatively associated with high-density lipoprotein (HDL). Low physical activity at leisure time was positively associated with triglycerides in the PM and PMT groups and negatively associated with HDL in the PM0 and PMT groups. High physical activity at work was positively associated with triglycerides in the PMT group and with total cholesterol in the PM0 group, but negatively associated with HDL in the PMT and transdermal groups. Body mass index was positively associated with triglycerides and negatively with HDL in all the groups regardless of the hormonal situation. The serum lipid profile as influenced by lifestyle factors was modified by the hormonal situation. Compared with the postmenopausal women without HT use, the use of HT contributes to fewer "negative" effects by lifestyle factors on serum lipids.

Colorectal cancer in middle-aged women in relation to hormonal status: a report from the Women's Health in the Lund Area (WHILA) study

OBJECTIVE

To delineate a perceived association of estradiol versus estradiol plus norethisterone hormone therapy on the prevalence of colorectal cancer in postmenopausal women.

METHODS

The Women's Health in the Lund Area (WHILA) project covers 10,766 women aged 50-60 years, living in the Lund area, Sweden. Out of this population, 6908 (64%) women completed questionnaires, underwent physical and laboratory assessments and had self-reported information regarding colorectal cancer. Four hundred and twenty-two (6%) were premenopausal (PM), 3600 (52%) were postmenopausal without hormone therapy (PM0), 2452 (36%) were postmenopausal with combined hormone therapy (PMT-HT) and 364 (5%) were postmenopausal with estrogen monotherapy (PMT-E).

RESULTS

There were 21 cases of colorectal cancer (0.3%), one in the PM group, 16 in the PM0 group, two in the PMT-HT group and another two in the PMT-E group. Colorectal cancer prevalence was lower in the PMT-HT than in the PM0 group (odds ratio (OR) = 0.18, 95% confidence interval (CI) = 0.04-0.80). However, for the PMT-E group, the OR (95% CI) was 1.02 (0.86-1.20). There was a positive association between low physical activity (p = 0.04), low parity (p = 0.02) and risk of colorectal cancer.

CONCLUSION

Combined hormone therapy seemed to be associated with a lower risk of colorectal cancer in postmenopausal women in contrast to estrogen monotherapy. Hence the progestin might have a protective role.

Obstructive airways diseases, smoking and use of inhaled corticosteroids in southern Sweden in 1992 and 2000

OBJECTIVE

To examine the prevalence of obstructive pulmonary diseases, respiratory symptoms, smoking habits and pulmonary medication in an adult population, and to compare the results with a study performed in the same geographical area in 1992.

DESIGN

In 2000, a postal questionnaire was sent to a randomly selected population of 5179 subjects aged 20-59 years living in southern Sweden.

RESULTS

The participation rate was 71.3%. Self-reported asthma was reported by 8.5% of all respondents (vs. 5.5% in 1992, P < 0.001) and 14.5% of females aged 20-29 years. Self-reported chronic bronchitis and/or emphysema and/or chronic obstructive pulmonary disease (CBE/COPD) was reported by 3.6% (vs. 4.6% in 1992, non-significant) with the highest prevalence (5.7%) in the 50-59 year cohort. Smoking decreased from 33.3% in 1992 to 28.4% in 2000 (P < 0.05). About 46% of asthmatics reported nocturnal respiratory symptoms, and 69% reported having had asthma symptoms in the last 12 months. Use of inhaled steroids increased in subjects with asthma and CBE/COPD from 19.4% to 36.5% (P < 0.05) and from 8.6% to 30.0% (P < 0.05), respectively.

CONCLUSIONS

Self-reported asthma increased significantly between 1992 and 2000, but the prevalence of CBE/COPD was unchanged. The high proportion of reported symptoms in asthmatics despite an increased use of steroids suggests that further efforts are needed to improve asthma treatment.

Prevalence of Hand Eczema in an Adult Swedish Population and the Relationship to Risk Occupation and Smoking

Using a postal questionnaire the prevalence of hand eczema was determined in a general population of 11,798 individuals aged 20-77 years who were randomly drawn from the population records. The response rate was 78.1%. One-year prevalence of hand eczema among women varied between 1.9% and 10.8%, with the highest figure among those aged 30-39 years. The corresponding figures for men were 2.3% and 5.6%, with the highest figure among those aged 20-29 years. Lifetime prevalence varied between 5.7% and 16.7% among women and between 5.2% and 9.5% among men. Using multiple logistic regression analysis female sex (OR=1.91, 95% CI 1.47-2.47) and smoking (OR=1.35, 95% CI 1.04-1.75) were independent risk factors for reporting 1-year prevalence of hand eczema, whereas age (OR=0.99, 95% CI 0.97-0.99) was inversely related to the 1-year prevalence of hand eczema. Aggregated risk occupation or categorized occupation such as medical and nursing work, production or service were not significantly associated with 1-year prevalence of hand eczema.

Beliefs about health and diabetes in men of different ethnic origin

AIM

This paper reports the findings of a study exploring the health and illness beliefs of men with diabetes, who were from different cultural backgrounds and living in Sweden.

BACKGROUND

No studies have been reported that have focused on the beliefs about health and illness in men with diabetes mellitus of different ethnic origin. Beliefs may affect self-care and care-seeking behaviour.

METHOD

An explorative study design and purposive sampling procedure was used. Focus-group interviews were held with 35 men with diabetes and aged between 39 and 78 years. Fourteen participants were born in Arabic countries, 10 in former Yugoslavia and 11 in Sweden.

FINDINGS

Important factors for health were the ability to be occupied/employed and economically independent and, especially among Arabs and former Yugoslavians, sexual functioning. Swedes focused on heredity, lifestyle and management of diabetes, while non-Swedes claimed the influence of supernatural factors and emotional stress related to the role of being an immigrant and migratory experiences as factors related to development of diabetes and having a negative influence on health. Swedes and Arabs described health as "freedom from disease" in contrast to many former Yugoslavians who described health as "wealth and the most important thing in life". Knowledge about diabetes was limited among the men studied, but Arabs showed an active information-seeking behaviour compared with Swedes and former Yugoslavians. Non-Swedish respondents, particularly Arabs, had sought help from health care professionals to a greater extent than Swedes, who were more likely to use self-care measures.

CONCLUSION

Being occupied/employed and having knowledge about the body and management of diabetes are important for positive health development. There are dissimilarities in beliefs about health and diabetes that influence self-care behaviour and health care seeking. Men's cultural backgrounds and spiritual beliefs need to be considered in diabetes care.

Is increased segmental motion early after lumbar discectomy related to poor clinical outcome 5 years later?

The purpose of the study was to compare segmental motion in the early postoperative phase after lumbar discectomy to the outcome 5 years postoperatively. The study population had radiologically verified symptomatic L4-L5 or L5-S1 lumbar disc herniation and was referred with an indication for lumbar discectomy. Radiostereometry was performed in the supine and standing positions. The L4-L5 and L5-S1 segments were analysed separately. L4-L5 segments adjacent to the operated L5-S1 segment constituted a reference segment for the operated L4-L5 and vice versa. Twenty-one patients were available for the follow-up at 5 years. Outcome was classified as functionally good or poor. Repeated or planned repeat surgery at the same level during follow-up was considered as poor outcome. The L4-L5 segments in the poor group showed different direction of sagittal rotation (anterior versus posterior) of L4 on L5 compared with the good group (p<0.01). On the L5-S1 segment, patients with poor outcome displayed an increased anterior translation of about 1 mm (p<0.01) compared with the reference segments. Our study suggests that increased inducible vertebral displacement in the early postoperative phase after discectomy is associated with a poor clinical outcome.

Cardiovascular risk factors in middle-aged women and the association with use of hormone therapy: results from a population-based study of Swedish women. The Women's Health in the Lund Area (WHILA) Study

OBJECTIVE

Cardiovascular diseases in women are multifactorial. Women carry different risk factors compared to men and these specific risk factors need to be delineated, particularly in relation to the hormonal situation, and effects of diet and lifestyle.

METHODS

Out of the total cohort of 10,766 women born 1935-1945 living in the Lund area of southern Sweden, 6917 women completed a generic questionnaire and underwent a physical and laboratory assessment. According to hormonal status, 492 women were premenopausal (PM), 3600 were postmenopausal without hormone therapy (HT) (PM0) and 2816 were postmenopausal with ever-use of HT (PMT). Major cardiovascular risk factors as well as level of education, diet, and degree of physical activity were assessed in relation to hormonal status.

RESULTS

Compared to the PM0 group, the women in the PMT group had a higher level of education, more often worked full time, more often had sedentary work and lived a more regular life. They also had a lower rate of cigarette consumption, lower waist-to-hip ratio and lower body mass index than women in the PM0 group. The PMT group had lower levels of serum total cholesterol, low density lipoprotein cholesterol, high density lipoprotein cholesterol and triglycerides than the PM0 group and also had lower systolic and diastolic blood pressures, a lower prevalence of type II diabetes mellitus, of deep venous thrombosis and of coronary artery disease. Low-risk factors for cardiovascular disease and high level of education were still associated with HT, after adjustment by multiple logistic regression. Major risk factors for coronary heart disease were similar between the PM and the PMT groups.

CONCLUSION

Use of HT is accompanied by a lower risk profile for cardiovascular disease and also by several factors indicating a healthier lifestyle.

Swedish and Middle-Eastern-born women's beliefs about gestational diabetes

OBJECTIVE

to compare beliefs about health and illness between women born in Sweden and the Middle East who developed gestational diabetes (GD).

DESIGN

a qualitative, explorative study using semi-structured interviews.

SETTING

in-hospital diabetes specialist clinic in Sweden.

PARTICIPANTS

consecutive sample of women with GD; 13 born in Sweden and 14 born in the Middle East.

MEASUREMENT AND FINDINGS

all the women described health as freedom from disease, and expressed worries for the baby's health and well-being. Women from the Middle East did not know the cause of GD, discussed the influence of social factors, such as being an immigrant, and supernatural factors, tried to adapt to the disease and thought it would disappear after birth, felt they had more pregnancy-related complications but had not received any treatment. Swedish women attributed GD to inheritance, environment and hormonal change, feared developing Type 2 diabetes, found work-related stress harmful to their health, more often sought help, used medications against pregnancy-related complications, and were more often on sick-leave from work.

KEY CONCLUSIONS

Swedish women initiated a battle against GD, demanded medical treatment for pregnancy-related complications because of gainful employment and viewed pregnancy as a disease. Women from the Middle East temporarily adapted to the disease and perceived pregnancy and related problems as a natural part of life.

IMPLICATIONS FOR PRACTICE

it is important to assess individual beliefs, risk awareness and to meet individual needs for information.
