Development of health-related quality of life and symptoms in patients with advanced cancer in Greenland.

A prospective national cohort study assessed the development of health-related quality of life (HRQoL) and symptoms in adult patients undergoing treatment and care for advanced cancer in Greenland. HRQol was examined by EORTC QLQ-C30 version 3.0 questionnaire monthly for 4 months. Changes over time and between-group comparisons were examined. Of 58 patients included in the study, 47% completed the questionnaire four times. Functioning was generally high, and improved social functioning was observed after 1 and 2 months. The highest symptom score was for fatigue followed by pain and nausea/vomiting. A high score for financial problems remained unchanged during the entire period. Patients with higher income had reduced pain intensity (p = .03) and diarrhoea (p = .05) than patients with income below the poverty line. After 1 month, reduction in pain intensity was observed for Nuuk citizens compared with non-Nuuk citizens (p = .05). After 2 months, non-Nuuk citizens reported improved social functioning compared with Nuuk citizens (p = .05). After 3 months, Global Health in Nuuk citizens was improved compared with non-Nuuk citizens (p = .05). An important clinical finding was that patients' needs for support are related to social status, and geographical factors should be taken into account when planning palliative care.

Dental status in nursing home residents with domiciliary dental care in Sweden.

OBJECTIVE: To describe the dental health status of elderly people in nursing homes receiving domiciliary dental care. DESIGN: Case note review. CLINICAL SETTING: Nursing homes in 8 Swedish counties. PARTICIPANTS: Care dependent elderly people (≥65 years). METHODS: Clinical data, including the number of remaining natural teeth, missing and decayed teeth (manifest dental caries) and root remnants, recorded by dentists according to standard practices. Medical and dental risk assessments were performed. RESULTS: Data were available for 20,664 patients. Most were women (69.1%), with a mean age of 87.1 years (SD 7.42, range 65-109). The mean age for men was 83.5 years (SD 8.12, range 65-105). Two or more medical conditions were present in most of the population. A total of 16,210 individuals had existing teeth of whom 10,974 (67.7%) had manifest caries. The mean number of teeth with caries was 5.0 (SD 5.93) corresponding to 22.8% of existing teeth. One in four individuals were considered to have a very high risk in at least one professional dental risk assessment category. CONCLUSIONS: Care dependent elderly in nursing homes have very poor oral health. There is a need to focus on the oral health-related quality of life for this group of frail elderly during their final period of life.

Excess protein intake relative to fiber and cardiovascular events in elderly men with chronic kidney disease.

BACKGROUND AND AIMS: The elevated cardiovascular (CVD) risk observed in chronic kidney disease (CKD) may be partially alleviated through diet. While protein intake may link to CVD events in this patient population, dietary fiber has shown cardioprotective associations. Nutrients are not consumed in isolation; we hypothesize that CVD events in CKD may be associated with dietary patterns aligned with an excess of dietary protein relative to fiber. METHODS AND RESULTS: Prospective cohort study from the Uppsala Longitudinal Study of Adult Men. Included were 390 elderly men aged 70-71 years with CKD and without clinical history of CVD. Protein and fiber intake, as well as its ratio, were calculated from 7-day dietary records. Cardiovascular events were registered prospectively during a median follow-up of 9.1 (inter-quartile range, 4.5-10.7) years. The median dietary intake of protein and fiber was 66.7 (60.7-71.1) and 16.6 (14.5-19.1) g/day respectively and the protein-to-fiber intake ratio was 4.0 (3.5-4.7). Protein-to-fiber intake ratio was directly associated with serum C-reactive protein levels. During follow-up, 164 first-time CVD events occurred (incidence rate 54.5/1000 per year). Protein-fiber intake ratio was an independent risk factor for CVD events [adjusted hazard ratio, HR per standard deviation increase (95% confidence interval, CI) 1.33 (1.08, 1.64)]. Although in opposing directions, dietary protein [1.18 (0.97, 1.44)], dietary fiber alone [0.81 (0.64, 1.02)], were not significantly associated with CVD events. CONCLUSIONS: An excess of dietary protein relative to fiber intake was associated with the incidence of cardiovascular events in a homogeneous population of older men with CKD.

Chronic non-cancer pain and the epidemic prescription of opioids in the Danish population: trends from 2000 to 2013.

BACKGROUND: Chronic pain has serious consequences for individuals and society. In addition, opioid prescription for chronic non-cancer pain (CNCP) has become more frequent. This study aims to examine the trends regarding the prevalence of CNCP, dispensed opioids, and concurrent use of benzodiazepine (BZD)/BZD-related drugs in the Danish population. METHODS: Data from the cross-sectional national representative Danish Health and Morbidity Surveys (2000, 2005, 2010, and 2013) were combined with The Danish National Prescription Registry at an individual level. The study populations varied between 5000 and 13,000 individuals ≥16 years (response rates: 51-63%). Respondents completed a self-administered questionnaire, which included the analyzed items on identification of chronic pain (≥6 months). RESULTS: From 2000 to 2013, the prevalence of CNCP increased and subsequently the annual prevalence of opioid use from 4.1% to 5.7% among CNCP individuals. Higher CNCP prevalence was related to female gender, no cohabitation partner, short education, non-Western origin, and overweight/obesity. In addition, women with CNCP, especially >65 years, became more frequent users of opioids and used higher doses than men. Concurrent use of BZD/BZD-related drugs decreased (13%) from 2010 to 2013, still one-third of long-term opioid user were co-medicated with these drugs. CONCLUSIONS: The use of opioids has increased in Denmark, especially among elderly women. The concurrent use of BZD/BZD-related drugs has decreased from 2010 to 2013, but still one-third of long-term opioid users were co-medicated.

Cross-sectional relationships between dietary fat intake and serum cholesterol fatty acids in a Swedish cohort of 60-year-old men and women.

BACKGROUND: The present study aimed to describe the relationship between self-reported dietary intake and serum cholesterol fatty acids (FAs) in a Swedish population of 60-year-old men and women. METHODS: Cross-sectional data collected in 1997-1998 from 4232 individuals residing in Stockholm County were used. Five diet scores were created to reflect the intake of saturated fats in general, as well as fats from dairy, fish, processed meat and vegetable oils and margarines. Gas chromatography was used to assess 13 FAs in serum cholesterol esters. The association between each diet score and specific FAs was assessed by percentile differences (PD) with 95% confidence intervals (CI) at the 10th, 25th, 50th, 75th and 90th percentile of each FA across levels of diet scores using quantile regression. RESULTS: Fish intake was associated with high proportions of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). For each point increase in fish score, the 50th PD in EPA and DHA was 32.78% (95% CI = 29.22% to 36.35%) and 10.63% (95% CI = 9.52% to 11.74%), respectively. Vegetable fat intake was associated with a high proportion of linoleic acid and total polyunsaturated fatty acids (PUFA) and a low proportion of total saturated fatty acids (SFA). The intake of saturated fats in general and dairy fat was slightly associated with specific SFA, although the intake of fat from meat was not. CONCLUSIONS: In the present study population, using a rather simple dietary assessment method, the intake of fish and vegetable fats was clearly associated with serum PUFA, whereas foods rich in saturated fats in general showed a weak relationship with serum SFA. Our results may contribute to increased knowledge about underlying biology in diet-cardiovascular disease associations.

Symptoms and side effects in chronic non-cancer pain patients: clinical implications and development of new assessment tools.

OBJECTIVE: To improve a 41-item screening tool evaluated in our previous study by making it more simple and convenient to patients and at the same time maintain the level of information and the sensitivity. METHODS: In a prospective, two-period questionnaire study, patients suffering from chronic pain of non-cancer origin for more than 6 months, were asked to fill in two questionnaires: QSSE-41 or QSSE-33 and SF-36. The first part of the study (QSSE-41) included an age- and sex-matched control group. RESULTS: A total of 67 patients were included in QSSE-41 and 60 patients in QSSE-33. In QSSE-41, the mean number of symptoms reported by the patient group (12.3) was significantly higher than those reported by the controls (6.8) (P < 0.001). Out of the total number of symptoms, 40.3% were reported to be side effects caused by analgesics, and out of those 61.3% were reported as acceptable and 38.7% as unacceptable side effects. In the QSSE-33, the mean number of symptoms reported by the patient group was 13.6. Out of the total number of symptoms, 46.3% were reported to be side effects caused by analgesics, and out of those 56.4% were reported as acceptable and 43.6% as unacceptable side effects. CONCLUSIONS: This new and shorter screening tool QSSE-33 may substitute the original QSSE-41 and in clinical use, contribute substantially to a more comprehensive and detailed understanding of symptoms/side effects and may consequently lead to improved therapies.

The evidence of neuraxial administration of analgesics for cancer-related pain: a systematic review.

BACKGROUND: The present systematic review analysed the existing evidence of analgesic efficacy and side effects of opioids without and with adjuvant analgesics delivered by neuraxial route (epidural and subarachnoid) in adult patients with cancer. METHODS: Search strategy was elaborated with words related to cancer, pain, neuraxial route, analgesic and side effects. The search was performed in PubMed, EMBASE, and Cochrane for the period until February 2014. Studies were analysed according to methods, results, quality of evidence, and strength of recommendation. RESULTS: The number of abstracts retrieved was 2147, and 84 articles were selected for full reading. The final selection comprised nine articles regarding randomised controlled trials (RCTs) divided in four groups: neuraxial combinations of opioid and adjuvant analgesic compared with neuraxial administration of opioid alone (n = 4); single neuraxial drug in bolus compared with continuous administration (n = 2); single neuraxial drug compared with neuraxial placebo (n = 1); and neuraxial opioid combined with or without adjuvant analgesic compared with other comprehensive medical management than neuraxial analgesics (n = 2). The RCTs presented clinical and methodological diversity that precluded a meta-analysis. They also presented several limitations, which reduced study internal validity. However, they demonstrated better pain control for all interventions analysed. Side effects were described, but there were few significant differences in favour of the tested interventions. CONCLUSION: Heterogeneous characteristics and several methodological limitations of the studies resulted in evidence of low quality and a weak recommendation for neuraxial administration of opioids with or without adjuvant analgesics in adult patients with cancer.

Renal function and symptoms/adverse effects in opioid-treated patients with cancer.

BACKGROUND: Renal impairment and the risk of toxicity caused by accumulation of opioids and/or active metabolites is an under-investigated issue. This study aimed at analysing if symptoms/adverse effects in opioid-treated patients with cancer were associated with renal function. METHODS: Cross-sectional multicentre study (European Pharmacogenetic Opioid Study, 2005-2008), in which 1147 adult patients treated exclusively with only one of the most frequently reported opioids (morphine/oxycodone/fentanyl) for at least 3 days were analysed. Fatigue, nausea/vomiting, pain, loss of appetite, constipation and cognitive dysfunction were assessed (EORTC QLQ-C30). Glomerular filtration rate (GFR) was estimated using Cockcroft-Gault (CG), Modification of Diet in Renal Disease (MDRD), and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI Creatinine) equations. RESULTS: Mild to severe low GFR was observed among 40-54% of patients. CG equation showed that patients with mild and moderate/severe low GFR on morphine treatment had higher odds of having severe constipation (P < 0.01) than patients with normal GFR. In addition, patients with moderate/severe low GFR on morphine treatment were more likely to have loss of appetite (P = 0.04). No other significant associations were found. CONCLUSION: Only severe constipation and loss of appetite were associated with low GFR in patients treated with morphine. Oxycodone and fentanyl, in relation to the symptoms studied, seem to be safe as used and titrated in routine cancer pain care.

Patient safety in domiciliary dental care for elderly nursing home residents in Sweden.

OBJECTIVE: To analyse patient safety in domiciliary dental care, with data from a quality registry. DESIGN: Retrospective analysis. CLINICAL SETTING: Domiciliary dental care, private caregiver, Sweden, 2012-2014. METHODS: All reported events in the quality registry at a provider of domiciliary dental care, (2012-05-01 to 2014-06-30) were categorized into 14 domains, and for severity as 'minor', 'moderate', or 'serious' events. The reported events were also independently assessed by an experienced reviewer for national requirements of reporting patient safety related events. RESULTS: The quality registry covered 724 (0.03%) reported events during 218,586 consecutive treatment sessions in domiciliary dental care, including 628,070 registered dental procedures. Fifty (6.9%) of the reported events were patient safety related, of which 11 (1.5%) events were reportedly of minor severity, 20 (2.8%) as moderate, and 19 (2.6%) as serious. For all degrees of severity, the most frequently reported events were related to problems with patient identity control (3.3%). None of the events required reporting to national authorities. CONCLUSIONS: Domiciliary dental care has a low frequency of patient safety related events (0.03% of all treatments). Identity controls need to be emphasised in nursing homes or where individuals are dependent on the care of others.

Health economic analyses of domiciliary dental care and care at fixed clinics for elderly nursing home residents in Sweden.

OBJECTIVES: Dental care for elderly nursing home residents is traditionally provided at fixed dental clinics, but domiciliary dental care is an emerging alternative. Longer life expectancy accompanied with increased morbidity, and hospitalisation or dependence on the care of others will contribute to a risk for rapid deterioration of oral health so alternative methods for delivering oral health care to vulnerable individuals for whom access to fixed dental clinics is an obstacle should be considered. The aim was to analyse health economic consequences of domiciliary dental care for elderly nursing home residents in Sweden, compared to dentistry at a fixed clinic. METHODS: A review of relevant literature was undertaken complemented by interviews with nursing home staff, officials at county councils, and academic experts in geriatric dentistry. Domiciliary dental care and fixed clinic care were compared in cost analyses and cost-effectiveness analyses. RESULTS: The mean societal cost of domiciliary dental care for elderly nursing home residents was lower than dental care at a fixed clinic, and it was also considered cost-effective. Lower cost of dental care at a fixed dental clinic was only achieved in a scenario where dental care could not be completed in a domiciliary setting. CONCLUSIONS: Domiciliary dental care for elderly nursing home residents has a lower societal cost and is cost-effective compared to dental care at fixed clinics. To meet current and predicted need for oral health care in the ageing population alternative methods to deliver dental care should be available.

Serum fatty acid patterns, insulin sensitivity and the metabolic syndrome in individuals with chronic kidney disease.

OBJECTIVES: The causes of the multiple metabolic disorders of individuals with chronic kidney disease (CKD) are not fully known. We investigated the relationships between dietary fat quality, the metabolic syndrome (MetS), insulin sensitivity and inflammation in individuals with CKD. SUBJECTS: Two population-based surveys were conducted in elderly Swedish individuals (aged 70 years) with serum cystatin C-estimated glomerular filtration rate <60 mL min(-1) /1.73 m2: the Uppsala Longitudinal Study of Adult Men (ULSAM) and the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) surveys. The present population comprised 274 men and 187 subjects (63% women) from the ULSAM and PIVUS cohorts, respectively. DESIGN: Factor analyses of serum fatty acids were used to evaluate dietary fat quality. Insulin sensitivity was measured by homeostasis model assessment of insulin resistance (IR) and, in ULSAM, also by euglycaemic clamp. RESULTS: Factor analyses generated two fatty acid patterns of (i) low linoleic acid (LA)/high saturated fatty acid (SFA) or (ii) high n-3 polyunsaturated fatty acid (n-3 PUFA) levels. In both surveys, the low LA/high SFA pattern increased the odds of having MetS [adjusted odds ratio 0.60 [95% confidence interval (CI) 0.44-0.81] and 0.45 (95% CI 0.30-0.67) per SD decrease in factor score in the ULSAM and PIVUS surveys, respectively] and was directly associated with both IR and C-reactive protein. The n-3 PUFA pattern was not consistently associated with these risk factors. CONCLUSIONS: A serum fatty acid pattern reflecting low LA and high SFA was strongly associated with MetS, IR and inflammation in two independent surveys of elderly individuals with CKD. At present, there are no specific dietary guidelines for individuals with CKD; however, these findings indirectly support current recommendations to replace SFAs with PUFAs from vegetable oils.

Serum selenium in relation to measures of glucose metabolism and incidence of Type 2 diabetes in an older Swedish population.

AIMS: The relation between selenium status and risk of Type 2 diabetes is controversial. We aimed to evaluate associations of serum selenium, a marker of dietary selenium, with measures of glucose metabolism and risk of diabetes. METHODS: We used data from a population-based, longitudinal cohort of 1925 Swedish men who were 50 years old and did not have diabetes at baseline in the 1970s. At baseline, an intravenous glucose tolerance test was performed and, at a follow-up examination after 20 years, an oral glucose tolerance test and a hyperinsulinaemic euglycaemic clamp for the assessment of insulin sensitivity were conducted. RESULTS: At baseline, the mean (standard deviation) selenium concentration was 75.6 (14.3) µg/l. During 20 years of follow-up, 88 incident cases of diabetes occurred in 1024 participants with follow-up data. Baseline serum selenium levels were not associated with risk of diabetes (odds ratio 1.06; 95% CI 0.83-1.38). Higher selenium levels were associated with lower early insulin response (standardized ß -0.08; 95% CI -0.14 to -0.03) at baseline after adjusting for potential confounders, but not with any other measures of ß-cell function or insulin sensitivity at baseline or follow-up. The association with early insulin response was non-significant after taking multiple testing into account. CONCLUSIONS: Our results do not support a role of dietary selenium in the development of disturbances in glucose metabolism or diabetes in older individuals.

Chronic pain and the development of a symptom checklist: a pilot study.

BACKGROUND: There is currently no instrument to systematically assess the range of symptoms/problems and their bothersomeness in patients with chronic non-cancer pain (CNPN). Systematic assessment and prioritizing may target treatments and improve outcomes. METHODS: The authors developed a checklist of symptoms and problems, the Copenhagen Symptom Checklist (CSC), presented clinically by patients. Fifty-three items representing biological, psychological and social areas were selected. Symptom/problem severity was rated on a 5-point scale anchored at 0 = 'not at all' and 4 = 'severe'. Patients ranked the five most bothersome symptoms/problems and could add five open-ended items. Patients completed the CSC after the first visit at the multidisciplinary pain centre. RESULTS: One hundred and twelve consecutive patients completed the CSC. Eighty-nine percent scored pain as rather severe or very severe (score = 3 plus score = 4), followed by reduction in physical activity (67%), fatigue (66%) and sleep disturbance (53%). Pain and fatigue, but not reduction in physical activity, were given highest priority. Cognitive problems were important to a third of the patients. Depressive symptoms, cognitive problems and worry explained 17.5% of the total variance. Patients filled in the CSC without important loss of information, but a minority prioritized more than three areas or used the free text alternative. CONCLUSIONS: Patients prioritized pain and fatigue as the most burdensome symptoms, but reduction in physical activity and sleep problems were also highly ranked. Patients were positive to the idea of symptom reporting; however, the 53-item number in this version of CSC is larger than may be necessary.

Pain characteristics and management of inpatients admitted to a comprehensive cancer centre: a cross-sectional study.

AIMS: This prospective, cross-sectional study aimed to assess cancer pain and its management in an inpatient setting at a comprehensive cancer centre in Denmark. METHODS: One hundred and eighty-eight inpatients with cancer were invited to participate (May/June 2011). Demographics, diagnoses, World Health Organization performance status, health-related quality of life, pain and data regarding analgesic treatment were registered. RESULTS: One hundred and thirty-four (71.3%) patients agreed to participate in the study. Most frequent diagnoses were leukaemia (27.6%) and lung cancer (14.2%). A high prevalence of pain was observed, 65.7%. Thirty-two per cent reported moderate to severe pain when it was at its worst, 96% reported no or mild pain when it was at its least. Nearly 22% reported moderate to severe pain when the pain was categorised as average. Breakthrough pain episodes were reported by 30.5%. Adjuvant medication was sparsely used and not always correctly indicated. Out of 88 patients with pain, 62.5% were left untreated according to the Electronic Medication System. Higher health-related quality of life was associated with lower pain intensity. The use of opioids with or without adjuvants was associated with higher pain intensity and higher number of breakthrough pain episodes. CONCLUSIONS: Approximately two thirds of inpatients reported pain and one third had breakthrough pain. A substantial number of patients with pain were left untreated. Opioid-treated patients reported highest pain intensity and number of breakthrough episodes; however, analgesic medication seemed to be underused. Measures to improve pain assessment and management are highly required.

Cognitive function in patients with chronic pain treated with opioids: characteristics and associated factors.

BACKGROUND: The paucity of studies regarding cognitive function in patients with chronic pain, and growing evidence regarding the cognitive effects of pain and opioids on cognitive function prompted us to assess cognition via neuropsychological measurement in patients with chronic non-cancer pain treated with opioids. METHODS: In this cross-sectional study, 49 patients were assessed by Continuous Reaction Time, Finger Tapping, Digit Span, Trail Making Test-B and Mini-mental State Examination tests. Linear regressions were applied. RESULTS: Patients scored poorly in the Trail Making Test-B (mean = 107.6 s, SD = 61.0, cut-off = 91 s); and adequately on all other tests. Several associations among independent variables and cognitive tests were observed. In the multiple regression analyses, the variables associated with statistically significant poor cognitive performance were female sex, higher age, lower annual income, lower schooling, anxiety, depression, tiredness, lower opioid dose, and more than 5 h of sleep the night before assessment (P < 0.05). CONCLUSIONS: Patients with chronic pain may have cognitive dysfunction related to some reversible factors, which can be optimized by therapeutic interventions.

Validation and usefulness of the Danish version of the Pain Medication Questionnaire in opioid-treated chronic pain patients.

BACKGROUND: Addiction is a feared complication of long-term opioid therapy for chronic pain patients. A screening tool to assess the potential risk of addiction may be helpful. METHODS: The Pain Medication Questionnaire (PMQ) was translated into Danish by a 'forward' and 'backward' translation procedure. Patients with chronic non-cancer pain and cancer pain treated at a tertiary pain center were screened for addiction using Portenoy's criteria and invited to answer the Danish version of the PMQ. RESULTS: Two hundred nine patients participated in the study. PMQ was able to discriminate between addicted and non-addicted patients. Patients with high PMQ scores indicating a risk of addiction drank more alcohol, smoked more tobacco, used higher doses of morphine, had a higher anxiety and depression score, and had poorer mental health. Using a cut-off score of 22, the PMQ had a sensitivity of 82%, but the specificity at this cut-point was 56%, indicating a risk of false positive cases. Convergent and discriminant validity were confirmed by correlation with opioid doses, alcohol and tobacco use, anxiety and depression scores, and inverse correlation with mental health and social role. Test-retest showed a very strong correlation. Cronbach's alpha for internal consistency was 0.61. Ten components were found to have eigenvalues above 1.0, confirming the multidimensional structure of the questionnaire. CONCLUSIONS: The PMQ may assist physicians in addiction risk assessment and stratification when treating chronic pain patients with opioids. PMQ is not a diagnostic tool and should only be used as an indicator for possible addiction problems.

Symptoms and side effects in chronic non-cancer pain: patient report vs. systematic assessment.

BACKGROUND: relieving distressing symptoms and managing the side effects of analgesics are essential in order to improve quality of life and functional capacity in chronic non-cancer pain patients. A quick, reliable and valid tool for assessing symptoms and side effects is needed in order to optimize treatment. We aimed to investigate the symptoms reported by chronic non-cancer pain patients after open-ended questioning vs. a systematic assessment using a list of symptoms, and to assess whether the patients could distinguish between the symptoms and the side effects induced by analgesics. METHODS: patients treated with either opioids and/or adjuvant analgesics were asked to report their symptoms spontaneously, followed by a 41-item investigator-developed symptom checklist. A control group also filled in the checklist. RESULTS: a total of 62 patients and 64 controls participated in the study. The numbers of symptoms reported by the patients (9.9 ± 5.9) were significantly higher than those reported by the controls (3.2 ± 3.9) (P<0.001). In the patient group, the number of spontaneously reported symptoms (1.3 ± 1.4) was significantly lower than the symptoms reported when using the symptom checklist (9.9 ± 5.9) (P<0.001). The six most frequently symptoms reported by the patients were: (1) Fatigue; (2) Memory deficits; (3) Dry mouth; (4) Concentration deficits; (5) Sweating; and (6) Weight gain. Out of the six most frequently reported symptoms, the share of side effects due to analgesics was: (1) Dry mouth (42%); (2) Sweating (34%); (3) Weight gain (29%); (4) Memory deficits (24%); (5) Fatigue (19%); and (6) Concentration deficits (19%). CONCLUSION: the number of symptoms reported using systematic assessment was eightfold higher than those reported voluntarily. Fatigue, cognitive dysfunction, dry mouth, sweating and weight gain were the most frequently reported. The patients reported the side effects of their analgesics to contribute substantially to the reported symptoms.

Attitudes and perceptions towards oral hygiene tasks among geriatric nursing home staff.

OBJECTIVES: To assess attitudes and perceptions towards oral hygiene tasks among geriatric nursing home staff, before and after a dental hygiene education. METHODOLOGY: A survey questionnaire was distributed to the nursing staff (n = 105), at a geriatric nursing home in Stockholm, Sweden. RESULTS: The response rate to the questionnaire was 83%. A vast majority (87%) of the nursing staff considered oral hygiene tasks unpleasant. The main reason for considering oral care unpleasant was a perceived unwillingness from the residents. The perceived unwillingness from the residents among the nursing staff was reduced after the dental hygiene education (chi-square test, P = 0.02). A vast majority of the nursing staff experienced, always or sometimes, resistance from the residents towards oral care. CONCLUSIONS: Nursing home staff members consider oral care tasks unpleasant, and frequently experience resistance from the nursing home residents towards oral care. The perceived unwillingness from the residents is reduced after an advanced dental hygiene education. Further studies are needed to evaluate the effects of education on nursing staff's attitudes and perceptions towards oral care tasks, with the overall aim of improving the oral health among older people in hospitals and nursing homes.

Adipose tissue fatty acids and insulin sensitivity in elderly men.

AIMS/HYPOTHESIS: Dietary fatty acids may affect insulin sensitivity. Adipose tissue fatty acid composition partly reflects long-term dietary intake, but data from large studies regarding relationships with insulin sensitivity are lacking. We aimed to determine the association between adipose tissue fatty acids and insulin sensitivity in elderly Swedish men. METHODS: In a cross-sectional analysis of the community-based Uppsala Longitudinal Study of Adult Men (n = 795, mean age 71 years), adipose tissue biopsies were obtained and fatty acid composition was determined by gas-liquid chromatography. Insulin sensitivity was measured directly by a euglycaemic clamp. RESULTS: Palmitic acid (16:0), the major saturated fatty acid (SFA) in the diet and in adipose tissue, was negatively correlated with insulin sensitivity (r = -0.14), as were 16:1 n-7 (r = -0.15), 20:3 n-6 (r = -0.31), 20:4 n-6 (r = -0.38), 22:4 n-6 (r = -0.37) and 22:5 n-3 (r = -0.24; p < 0.001 for all). Some minor SFAs were positively correlated; 12:0 (r = 0.46), 14:0 (r = 0.32), 17:0 (r = 0.21) and 18:0 (r = 0.41; p < 0.001 for all), as were essential polyunsaturated fatty acids (PUFAs) 18:2 n-6 (r = 0.10, p < 0.01) and 18:3 n-3 (r = 0.16, p < 0.001). Docosahexaenoic acid (22:6 n-3) was negatively correlated (r = -0.11, p < 0.01), whereas eicosapentaenoic acid (20:5 n-3) was not (r = -0.02, NS). Most associations diminished or disappeared in lean individuals, indicating an effect of obesity. CONCLUSIONS/INTERPRETATION: Adipose tissue enriched with palmitic acid and depleted of essential PUFAs is associated with insulin resistance. The positive association between minor SFAs and insulin sensitivity merits further investigation.
