  • Risk factors for low back pain and sciatica in elderly men-the MrOS Sweden study
  • 2017
  • Ingår i: Age and Ageing. - : Oxford University Press (OUP). - 0002-0729 .- 1468-2834. ; 46:1, s. 64-71

    • INTRODUCTION: the aim of this study was to identify whether factors beyond anatomical abnormalities are associated with low back pain (LBP) and LBP with sciatica (SCI) in older men. MATERIAL AND METHODS: Mister Osteoporosis Sweden includes 3,014 men aged 69-81 years. They answered questionnaires on lifestyle and whether they had experienced LBP and SCI during the preceding 12 months. About 3,007 men answered the back pain (BP) questions, 258 reported BP without specified region. We identified 1,388 with no BP, 1,361 with any LBP (regardless of SCI), 1,074 of those with LBP also indicated if they had experienced LBP (n = 615), LBP+SCI (n = 459). RESULTS: about 49% of those with LBP and 54% of those with LBP+SCI rated their health as poor/very poor (P < 0.001). Men with any LBP to a greater extent than those without BP had poor self-estimated health, depressive symptoms, dizziness, fall tendency, serious comorbidity (diabetes, stroke, coronary heart disease, pulmonary disease and/or cancer) (all P < 0.001), foreign background, were smokers (all P < 0.01), had low physical activity and used walking aids (all P < 0.05). Men with LBP+SCI to a greater extent than those with LBP had lower education, lower self-estimated health, comorbidity, dizziness and used walking aids (all P < 0.001). CONCLUSIONS: in older men with LBP and SCI, anatomical abnormalities such as vertebral fractures, metastases, central or lateral spinal stenosis or degenerative conditions may only in part explain prevalent symptoms and disability. Social and lifestyle factors must also be evaluated since they are associated not only with unspecific LBP but also with LBP with SCI.

  • Costs for screening, intervention and hospital treatment generated by the Malmö Preventive Project: a large-scale community screening programme.
  • 2002
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 251:1, s. 44-52

    • OBJECTIVES: The purpose of this study was to estimate retrospectively the costs of health care resources used in the Malmö Preventive Project, Sweden and estimate the costs of in-patient care that were avoided because of early intervention. SETTING AND SUBJECTS: A large-scale community intervention programme was conducted from 1974 to 1992 in Malmö, Sweden with the aim of reducing morbidity and mortality of cardiovascular diseases (CVD), alcohol related illnesses, and breast cancer. Between 1974 and 1992, 33 336 male and female subjects were screened for hypertension, hyperlipidaemia, type-2 diabetes and alcohol abuse. Intervention programmes that included life-style modifications, follow-up visits with physicians and nurses and drug therapy were offered to about 25% of screened subjects. METHODS: Recruitment costs were generated through out the screening period. Intervention costs were estimated for 5 years after screening. Excess in-patient care costs were estimated by subtracting hospital consumption for an unscreened, matched cohort from that of the screened cohort over follow-up periods of 13-19 years. Intervention and excess in-patient care costs were estimated until 1996. RESULTS: The net expenditures for recruitment and intervention was SEK253 million and saved costs for in-patient care of SEK143 millions (1998 prices). Considering the opportunity cost of the resources used in the study, the net cost rises to about SEK200 millions. CONCLUSIONS: The results suggest that only part of the intervention costs were offset by reduction in future morbidity health care costs. This is in line with results from prospective analyses of other primary prevention programmes.

  • Dispersion of viable pig liver cells with collagenase
  • 1975
  • Ingår i: Life Sciences. - : Elsevier BV. - 1879-0631 .- 0024-3205. ; 17:8, s. 1219-1225

    • Viable suspended hepatocytes were prepared from surgical biopsy specimens of pig and human liver by digestion with collagenase. Initial perfusion of the tissue through cannulated blood vessels with 0.5 mM EGTA followed by 0.2% collagenase gave the best results. 20−870 × 106 cells of which 60–95 % excluded trypan blue were obtained from 5–30 g pig liver pieces, while results with human liver specimens were usually less satisfactory. In some experiments, however, viable cells, as judged by vital stain exclusion and ability to synthesize lipids were obtained in sufficient yield. In the pig hepatocytes glycerolipid synthesis from [3H] glycerol and oxidation and esterification of [14C] oleic acid had the same characteristics as those observed earlier in rat hepatocytes.

  • The enigma of increased non-cancer mortality after weight loss in healthy men who are overweight or obese.
  • 2002
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 252:1, s. 70-78
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To study effects on non-cancer mortality of observational weight loss in middle-aged men stratified for body mass index (BMI), taking a wide range of possible confounders into account. Design. Prospective, population based study. Setting. Male population of Malmö, Sweden. Participants. In all 5722 men were screened twice with a mean time interval of 6 years in Malmö, southern Sweden. They were classified according to BMI category at baseline (<21, 22-25, overweight: 26-30, and obesity: 30+ kg m-2) and weight change category until second screening (weight stable men defined as having a baseline BMI ± 0.1 kg m-2 year-1 at follow-up re-screening). Main outcome measures. Non-cancer mortality calculated from national registers during 16 years of follow-up after the second screening. Data from the first year of follow-up were excluded to avoid bias by mortality caused by subclinical disease at re-screening. Results. The relative risk (RR; 95% CI) for non-cancer mortality during follow-up was higher in men with decreasing BMI in all subgroups: RR 2.64 (1.46-4.71, baseline BMI <21 kg m-2), 1.39 (0.98-1.95, baseline BMI 22-25 kg m-2), and 1.71 (1.18-2.47, baseline BMI 26+ kg m-2), using BMI-stable men as reference group. Correspondingly, the non-cancer mortality was also higher in men with increasing BMI, but only in the obese group (baseline BMI 26+ kg m-2) with RR 1.86 (1.31-2.65). In a subanalysis, nonsmoking obese (30+ kg m-2) men with decreased BMI had an increased non-cancer mortality compared with BMI-stable obese men (Fischer's test: P=0.001). The mortality risk for nonsmoking overweight men who increased their BMI compared with BMI-stable men was also significant (P=0.006), but not in corresponding obese men (P=0.094). Conclusions. Weight loss in self-reported healthy but overweight middle-aged men, without serious disease, is associated with an increased non-cancer mortality, which seems even more pronounced in obese, nonsmoking men, as compared with corresponding but weight-stable men. The explanation for these observational findings is still enigmatic but could hypothetically be because of premature ageing effects causing so-called weight loss of involution.

  • Improved outcome in Wegener's granulomatosis and microscopic polyangiitis? A retrospective analysis of 95 cases in two cohorts
  • 2009
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 265:4, s. 496-506
  • Tidskriftsartikel (refereegranskat)abstract
    • Mortality rates for Wegener's granulomatosis (WG) and microscopic polyangiitis (MPA) have decreased after the introduction of cyclophosphamide. Standardized mortality ratio (SMR) expresses the overall mortality of patients compared with the general population. The aims of this study were to compare survival in an old and a recent cohort of patients with WG and MPA using SMR and to determine predictors for death in both groups combined. Survival analyses were performed by Kaplan-Meier survival curves, SMR and proportional hazards regression models. The nephrology and rheumatology clinics at Linkoping University Hospital, Sweden. All patients diagnosed with WG or MPA in the catchment area during 1978-2005 were divided into two cohorts; patients diagnosed before (n = 32, old cohort) and after (n = 63, recent cohort) December 31, 1996. The two cohorts differed regarding the proportion of WG (75% vs. 56%, P = 0.03) and a tendency for more pronounced kidney involvement in the old cohort: 266 mu mol L-1 (16% dialysis-dependent) vs. 192 mu mol L-1 (5% dialysis-dependent), but were comparable regarding disease severity. SMR at 1 and 5 years were 2.1 (95% CI: 0.43-6.09) and 1.6 (95% CI: 0.6-3.2) in the recent cohort and 5.2 (95% CI: 1.07-15.14) and 2.5 (95% CI: 0.93-5.52) in the old cohort. Five-year survival was 87% and 81%. Serum creatinine, age, end-stage renal disease, diagnosis before 1997 and first relapse were independent predictors for death. Patient survival in WG and MPA analysed with SMR may be better than previously believed. Severe renal disease and disease relapse were the major predictors of reduced survival.

  • Inferior physical performance tests in 10,998 men in the MrOS study is associated with recurrent falls
  • 2012
  • Ingår i: Age and Ageing. - : Oxford University Press (OUP). - 0002-0729 .- 1468-2834. ; 41:6, s. 740-746
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: recurrent fallers are at especially high risk for injuries. Objective: to study whether tests of physical performance are associated with recurrent falls. Subjects: a total of 10,998 men aged 65 years or above. Methods: questionnaires evaluated falls sustained 12 months preceding testing of grip strength, timed stand, 6-m walk and 20-cm narrow walk test. Means with 95% confidence interval (95% CI) are reported. P < 0.01 is a statistically significant difference. Results: in comparison to both occasional fallers and non-fallers, recurrent fallers performed more poorly on all the physical ability tests (all P < 0.001). A score below -2 standard deviations (SDs) in the right-hand grip strength test was associated with an odds ratio of 2.4 (95% CI 1.7, 3.4) for having had recurrent falls compared with having had no fall and of 2.0 (95% CI 1.3, 3.4) for having had recurrent falls compared with having had an occasional fall. Conclusion: low performance in physical ability tests are in elderly men associated with recurrent falls.

  • Population-attributable risk of coronary heart disease risk factors during long-term follow-up: the Malmö Preventive Project.
  • 2006
  • Ingår i: Journal of Internal Medicine. - : Wiley. - 1365-2796 .- 0954-6820. ; 260:2, s. 134-141
  • Tidskriftsartikel (refereegranskat)abstract
    • Aims To calculate the population-attributable risk (PAR) of coronary events (CE) from 10 risk factors, during long-term follow-up. Methods We used both case-cohort and case-control analyses for calculation of PAR in relation to 10 baseline risk factors. First CE (fatal or nonfatal, n = 3072) in 22 444 males and 10 902 females was recorded during a mean follow-up of 20 years by use of national registers. Results Using a Cox regression analysis in a case-cohort design, smoking (prevalence in men 49%, women 37%) was the strongest risk factor, RR 2.29 (95% CI 2.09-2.52; PAR 39%), followed by hypercholesterolaemia, RR 1.70 (95% CI 1.56-1.86; PAR 18%), and diabetes, RR 1.67 (95% CI 1.41-1.99; PAR 3%). For women the strongest risk factors were smoking, RR 3.16 (95% CI 2.50-3.98; PAR 44%), diabetes, RR 2.59 (95% CI 1.78-3.76; PAR 6%), and hypertension, RR 2.47 (95% CI 1.94-3.14; PAR 23%). In men, smoking was the strongest predictor both after 10 years [RR 2.69 (95% CI 2.23-3.24)] and 20 years [RR 2.45 (95% CI 2.15-2.79)], followed by hypercholesterolaemia (RR 2.16-1.63), hypertension (RR 2.04-1.51), and diabetes (RR 1.85 -1.47). The case-control design gave very similar results. Total PAR varied from 74% (fully adjusted Cox regression, case-control, in men) to 116% in women (case-cohort). Conclusion Smoking is the most important long-term risk factor for CE in both genders, based on data from a population with a high proportion of smokers. Ten measured variables explained almost all variation in risk and could be used as a basis for intervention programmes.

  • Hydrolysis of galactolipids by human pancreatic lipolytic enzymes and duodenal contents
  • 1995
  • Ingår i: Journal of Lipid Research. - 1539-7262. ; 36:6, s. 1392-1400
  • Tidskriftsartikel (refereegranskat)abstract
    • Monogalactosyldiacylglycerols (MGDG), digalactosyldiacylglycerols (DGDG) and sulfoquinovosyldiacylglycerols (SQDG) are major lipids in vegetable food. Their digestion and absorption are unknown. This study examines the hydrolysis of galactolipids in vitro with human duodenal contents, pancreatic juice, and purified human pancreatic lipases. Galactolipids were incubated with human duodenal contents, pancreatic juice, pure pancreatic carboxyl ester lipase (CEL), and colipase-dependent lipase with colipase (Lip-Col). Hydrolysis was estimated as release of free fatty acids and by the use of [3H]galactose or [3H]fatty acid-labeled DGDG. Pancreatic juice and duodenal contents hydrolyzed DGDG to fatty acids, digalactosylmonoacylglycerol (DGMG) and water-soluble galactose-containing compounds. The hydrolysis of DGDG was bile salt-dependent and had a pH optimum at 6.5-7.5. Human pancreatic juice released fatty acids from MGDG, DGDG, and SQDG. Purified CEL hydrolyzed all three substrates; the hydrolysis rate was MGDG > SQDG > DGDG. Pure Lip-Col had activity toward MGDG but had little activity against DGDG. Separation of pancreatic juice by Sephadex G100 gel filtration chromatography revealed two peaks with galactolipase activity that coincided with CEL (molecular mass 100 kD) and lipase (molecular mass 50 kD) peaks. In contrast to pure Lip-Col enzymes of the latter peak were as active against DGDG as against MGDG. Thus, DGDG is hydrolyzed both by CEL and by a pancreatic enzyme(s) with a molecular mass of 40-50 kD to fatty acids and lyso DGDG. MGDG, DGDG, and SQDG are all hydrolyzed by human pancreatic juice. Pure CEL hydrolyzed all three substrates.
