Tidskriftsartikel (refereegranskat)abstract
- Lower ambient temperature (Ta) requires greater energy expenditure to sustain body temperature. However, effects of Ta on human energetics may be buffered by environmental modification and behavioral compensation. We used the IAEA DLW database for adults in the USA (n = 3213) to determine the effect of Ta (−10 to +30°C) on TEE, basal (BEE) and activity energy expenditure (AEE) and physical activity level (PAL). There were no significant relationships (p > 0.05) between maximum, minimum and average Ta and TEE, BEE, AEE and PAL. After adjustment for fat-free mass, fat mass and age, statistically significant (p < 0.01) relationships between TEE, BEE and Ta emerged in females but the effect sizes were not biologically meaningful. Temperatures inside buildings are regulated at 18–25°C independent of latitude. Hence, adults in the US modify their environments to keep TEE constant across a wide range of external ambient temperatures.

- Objectives. To study whether there is an increased fracture incidence following thyrotoxicosis. Design. A case-control study. Setting. Malmo University Hospital, Malmo, Sweden. Subjects: All patients (n = 333) from the population of Malmo who were treated for thyrotoxicosis for the first time during the 5-year period 1970-74. A total of 618 controls were selected from the local municipality registry in Malmo. For each case the aim was to randomly select two age- and gender-specific controls, alive in 1993 and born the same year and month as the case. Main outcome measures. Fracture incidence. Results. Comparing survivors, there were no differences in the percentage of individuals with fractures (all, fragility, non-fragility) between the patients and the controls. Comparing all individuals and including all fractures, the percentage of individuals with fractures in the entire female patient group (24.6%) was lower (P < 0.05) than in female controls (33.1%). There was a similar but non-significant pattern between male patients and controls. The mean number of all fractures was lower in male patients than in controls (P < 0.05), but no significant difference was noted between female patients and controls. For fragility fractures, there were no significant differences in the percentage of individuals with fractures or in the mean number of fractures between female or male patients and controls. Conclusion. In conclusion we found no increased incidence of fragility fractures in patients with previous thyrotoxicosis as compared with controls. Our results do not support the suggestion that screening for osteoporosis should be performed in patients with previous thyrotoxicosis.

- OBJECTIVES: Post-stroke cognitive impairment (PSCI) has considerable impact on patients and society. However, long-term studies on PSCI are scarce and may be influenced by assessment methods and selection bias. We aimed to (i) assess the prevalence of long-term PSCI; (ii) compare two common cognitive assessment instruments; and (iii) compare cognitive function of long-term stroke survivors with non-stroke persons.METHODS: Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were administered to 10-year survivors from a population-based cohort of first-ever stroke patients included in the Lund Stroke Register, Sweden, in 2001-2002. PSCI was defined as MMSE<27 and/or MoCA<25 and severe cognitive impairment as MMSE<23. Age- and sex-matched non-stroke control subjects who had performed MMSE (but not MoCA) were recruited from the longitudinal population study "Good Ageing in Skåne." The odds of having cognitive impairment for stroke survivors compared to controls were examined with logistic regression analyses adjusting for education.RESULTS: Of 145 stroke survivors after 10 years, 127 participated. MMSE showed PSCI in 46%, whereas MoCA displayed PSCI in 61%. Among the stroke survivors with MoCA<25, 35% had MMSE≥27 (P<.001). The odds of having severe cognitive impairment defined as MMSE<23 were higher among the stroke survivors compared to 354 controls (education-adjusted; OR=2.5; P=.004).CONCLUSIONS: Post-stroke cognitive impairment was prevalent among 10-year stroke survivors, and the odds of having severe cognitive impairment were higher among the stroke survivors compared to non-stroke persons. The burden of long-term PSCI might have been underestimated previously, and MoCA may be more suitable than MMSE to detect long-term PSCI.

- The aim of the study was to determine dietary risk factors for fracture in men aged 46-68 years. Six thousand five hundred and seventy-six men were randomly invited using the Municipal Registry to a diet and health study. The diet was assessed using a combined 7-day menu book for hot meals, beverages and dietary supplements and a quantitative food frequency questionnaire for other foods. The fracture incidence was 103/10,000 person-years during a mean follow-up of 2.4 years. Zinc and phosphorus intake were associated with fracture risk and showed a threshold effect. The zinc intake in the lowest decentile, 10 mg daily, was associated with almost a doubled risk of fracture compared with the fourth and fifth quintiles (RR = 0.47; 95% confidence interval, 27-82) of zinc intake adjusted for energy, previous fractures, lifestyle factors and co-morbidity. Energy-adjusted phosporus intake in the lowest quintile, mean level 1357 mg, was associated with an increased fracture risk compared with subjects in the second quintile. Smoking, martial status and physical activity were independently associated with fracture risk. Calcium, retinol and vitamin D showed no associations with fracture risk. We conclude that inadequate intakes of zinc and phosporus are important risk factors for fracture.

- Circulating proteins are vital in human health and disease and are frequently used as biomarkers for clinical decision-making or as targets for pharmacological intervention. Here, we map and replicate protein quantitative trait loci (pQTL) for 90 cardiovascular proteins in over 30,000 individuals, resulting in 451 pQTLs for 85 proteins. For each protein, we further perform pathway mapping to obtain trans-pQTL gene and regulatory designations. We substantiate these regulatory findings with orthogonal evidence for trans-pQTLs using mouse knockdown experiments (ABCA1 and TRIB1) and clinical trial results (chemokine receptors CCR2 and CCR5), with consistent regulation. Finally, we evaluate known drug targets, and suggest new target candidates or repositioning opportunities using Mendelian randomization. This identifies 11 proteins with causal evidence of involvement in human disease that have not previously been targeted, including EGF, IL-16, PAPPA, SPON1, F3, ADM, CASP-8, CHI3L1, CXCL16, GDF15 and MMP-12. Taken together, these findings demonstrate the utility of large-scale mapping of the genetics of the proteome and provide a resource for future precision studies of circulating proteins in human health.

Tidskriftsartikel (refereegranskat)abstract
- Background: SARS-CoV-2, the causal agent of COVID-19, enters human cells using the ACE2 (angiotensin-converting enzyme 2) protein as a receptor. ACE2 is thus key to the infection and treatment of the coronavirus. ACE2 is highly expressed in the heart and respiratory and gastrointestinal tracts, playing important regulatory roles in the cardiovascular and other biological systems. However, the genetic basis of the ACE2 protein levels is not well understood.Methods: We have conducted the largest genome-wide association meta-analysis of plasma ACE2 levels in >28 000 individuals of the SCALLOP Consortium (Systematic and Combined Analysis of Olink Proteins). We summarize the cross-sectional epidemiological correlates of circulating ACE2. Using the summary statistics-based high-definition likelihood method, we estimate relevant genetic correlations with cardiometabolic phenotypes, COVID-19, and other human complex traits and diseases. We perform causal inference of soluble ACE2 on vascular disease outcomes and COVID-19 severity using mendelian randomization. We also perform in silico functional analysis by integrating with other types of omics data.Results: We identified 10 loci, including 8 novel, capturing 30% of the heritability of the protein. We detected that plasma ACE2 was genetically correlated with vascular diseases, severe COVID-19, and a wide range of human complex diseases and medications. An X-chromosome cis-protein quantitative trait loci-based mendelian randomization analysis suggested a causal effect of elevated ACE2 levels on COVID-19 severity (odds ratio, 1.63 [95% CI, 1.10-2.42]; P=0.01), hospitalization (odds ratio, 1.52 [95% CI, 1.05-2.21]; P=0.03), and infection (odds ratio, 1.60 [95% CI, 1.08-2.37]; P=0.02). Tissue- and cell type-specific transcriptomic and epigenomic analysis revealed that the ACE2 regulatory variants were enriched for DNA methylation sites in blood immune cells.Conclusions: Human plasma ACE2 shares a genetic basis with cardiovascular disease, COVID-19, and other related diseases. The genetic architecture of the ACE2 protein is mapped, providing a useful resource for further biological and clinical studies on this coronavirus receptor.

Tidskriftsartikel (refereegranskat)abstract
- We have previously observed that pyridoxine treatment reduced plasma total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol concentrations and increased antithrombin III (AT III) activity in atherosclerotic patients with subnormal plasma pyridoxal 5-phosphate (PLP) levels. In order to confirm these results, we selected 17 males with low plasma PLP levels from a group of 122 80-year-old males in whom PLP has been determined. After supplementation with 120 mg of pyridoxine per day for 8 weeks their mean plasma TC and LDL cholesterol concentrations were decreased by 10% (p less than 0.01) and 17% (p less than 0.001), respectively. There was no effect on high-density lipoprotein cholesterol and triglycerides but plasma AT III activity was increased by 6% (p less than 0.05). The mechanism by which pyridoxine acts is unclear but it is hypothesized that pyridoxine-derived PLP may enhance the catabolism of LDL and the activity of AT III by inhibiting their glycosylation.

- BACKGROUND: Coffee drinking has been implicated in mortality and a variety of diseases but potential mechanisms underlying these associations are unclear. Large-scale systems epidemiological approaches may offer novel insights to mechanisms underlying associations of coffee with health.OBJECTIVE: We performed an analysis of known and novel protein markers linked to cardiovascular disease and their association with habitual coffee intake in the Prospective Study of the Vasculature in Uppsala Seniors (PIVUS, n=816) and followed-up top proteins in the Uppsala Longitudinal Study of Adult Men (ULSAM, n=635) and EpiHealth (n=2418).METHODS: In PIVUS and ULSAM, coffee intake was measured by 7-day dietary records while a computer-based food frequency questionnaire was used in EpiHealth. Levels of up to 80 proteins were assessed in plasma by a proximity extension assay.RESULTS: Four protein-coffee associations adjusted for age, sex, smoking and BMI, met statistical significance in PIVUS (FDR<5%, P<2.31×10(-3) ): leptin (LEP), chitinase-3-like protein 1 (CHI3L), Tumor necrosis factor (TNF) receptor 6 and TNF-related apoptosis-inducing ligand. The inverse association between coffee intake and LEP replicated in ULSAM (β, -0.042 SD per cup of coffee, P=0.028) and EpiHealth (β, -0.025 SD per time of coffee, P=0.004). The negative coffee-CHI3L association replicated in EpiHealth (β, -0.07, P=1.15×10(-7) ), but not in ULSAM (β, -0.034, P=0.16).CONCLUSIONS: The current study supports an inverse association between coffee intake and plasma LEP and CHI3L1 levels. The coffee-CHI3L1 association is novel and warrants further investigation given links between CHI3L1 and health conditions that are also potentially influenced by coffee.

A prospective study of orthostatic blood pressure in diabetic patients
- 1998

Ingår i: Clinical Autonomic Research. - 0959-9851. ; 8:4, s. 189-193
-
Tidskriftsartikel (refereegranskat)abstract
- To clarify whether orthostatic blood pressure is affected by the type of diabetes, cardiac autonomic neuropathy, and the duration of diabetes, orthostatic blood pressure (passive 90°tilt) was evaluated in 102 patients with insulin dependent diabetes mellitus (IDDM), 51 patients with non-insulin dependent diabetes mellitus (NIDDM), and in 238 control subjects in a first study followed up after 8 to 17 years. The heart rate reaction during deep breathing (E/I ratio) and to tilt (acceleration and brake indices) assessed cardiac autonomic function. In the first study, the lowest systolic blood pressure (LSBP) and the lowest diastolic blood pressure (LDBP) after tilt were significantly lower in IDDM patients compared with NIDDM patients (p < 0.001 for LSBP and p < 0.05 for LDBP) and controls (p < 0.001). LDBP was, however, also significantly lower (p < 0.05) in NIDDM patients than in controls. Hence, although most severe in IDDM, LDBP was disturbed in both types of diabetes. In IDDM, a low E/I ratio was associated with disturbed orthostatic blood pressure. At follow-up examinations, orthostatic blood pressure deteriorated in NIDDM but not in IDDM patients. In conclusion, LSBP and LDBP were impaired in IDDM patients compared with NIDDM and control subjects; however, LDBP was also impaired in NIDDM patients compared with controls. When the duration of diabetes increased, orthostatic blood pressure deteriorated in NIDDM but not in IDDM patients.

Association between cardiovascular disease- and inflammation-related serum biomarkers and poor lung function in elderly
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Background: Cardiovascular disease (CVD) is a common comorbidity in chronic obstructive pulmonary disease (COPD) and reduced lung function is an important risk factor for CVD and CVD-related death. However, the mechanisms behind the increased risk for CVD in COPD patients are not fully understood. Methods: We examined the association between CVD- and inflammation-related serum biomarkers, and pulmonary function in a geriatric population. 266 biomarkers related to CVD and inflammation were analyzed in blood samples from 611 subjects aged 66–86 years who participated in the Good Aging in Skåne study. Serum levels were assessed by a proximity extension assay. Pulmonary function was measured using the lower limit of normality (LLN) spirometry criteria, i.e., forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) < LLN. Logistic regression models were implemented and multiple comparisons were accounted for. Results: 10.3% of the study participants fulfilled pulmonary function decline criteria according to LLN. Out of the 266 biomarkers, only plasminogen activator, urokinase receptor (PLAUR) was statistically significantly associated with decreased pulmonary function. We could not find a statistically significant association between pulmonary function decline and other biomarkers previously linked to COPD, such as interleukin 6, tumor necrosis factor and surfactant protein D. Conclusion: We found that serum levels of PLAUR are associated with pulmonary function decline in older adults. PLAUR is activated following inflammation and promotes matrix metallopeptidase (MMP) activation and extracellular matrix (ECM) degradation. This implies that PLAUR could play a role in the early phase of COPD pathogenesis.

Tidskriftsartikel (refereegranskat)abstract
- The objective was to examine relationships between meat and other food items which have been associated with higher risk of cancer in the colon and prostate in some epidemiological studies. The study was conducted as a population-based cohort study comprising 11648 subjects (4816 male and 6742 female) born between 1926 and 1945 and living in the city of Malmo, Sweden. Data on mean daily intake of foods and nutrients were assessed with a diet history method combining a 7-day menu book and a food frequency questionnaire. Increasing meat intake, expressed in quintiles and adjusted for energy, was associated with decreasing intakes of poultry, fish, fruits, bread, cereals and cheese in both sexes. Low negative correlations between meat intake and ascorbic acid (r = -0.11) and fiber (r = -0.16 to -0.20) were noted. The average intake of fat from meat out of total fat intake was 13.6% in men and 11.9% in women. No major associations were noted between meat and the cholesterol raising fatty acids C:12:0, C:14:0, C:160 nor for C:20:4 or its precursor C:18:2. In conclusion, our findings indicate that meat consumption is negatively associated with food groups rich in antioxidants and fiber and the positive covariance reported between meat and cancer and coronary heart disease might, therefore, not be directly linked to components in meat.

Increased medical attention needed for frail elderly initially admitted to the emergency department for lack of community support
- 1999

-
Tidskriftsartikel (refereegranskat)abstract
- The demographic changes in society with growing numbers of elderly subjects will inevitably increase admission rates to acute emergency departments (AMU). Early discharge might augment emergency readmissions due to a relapse in medical conditions. Our aim was to study precipitating factors in frail elderly patients who got the diagnosis 'lack of community support' after initial medical examination at an AMU, as well as discharge rates and one-year mortality. The study population was 380 cases of 18 015 patients attending the AMU at a city hospital during one year. Inclusion criteria were age above 65 years, and given the diagnosis 'lack of community support' by a physician, defined as no other etiological or symptom diagnosis after an initial medical examination, and in some cases 24 to 48-hours observation. All but three medical records were checked. Reduced ability to eat, drink and walk prior to admission were noted among 22 to 58% of cases. Two thirds of the patients needed further medical care as inpatients, and physical medical causes were identified in 85% of the cases (mean number 3 causes); infectious diseases, cardiovascular diseases, dementia and trauma were the most prevalent factors. The median hospital stay was 14 days, and 10% had been discharged from the hospital the week prior to admission. The one-year mortality was 34%. The deceased had more precipitating physical causes, and were more often admitted to medical wards, but fewer had been referred to a senior consultant at the time of admission than survivors, adjusted for age (14% vs 42%, p<0.05). Multiple medical conditions were noted in the majority of patients admitted to an emergency department with reduced abilities to cope with basic activities of daily life, even though a preliminary examination stated lack of social support as the underlying cause. The need for better medical attention seems important, especially for patients discharged directly home from an emergency department.

Increased sweat sodium concentration in patients with Alzheimer's disease
- 1993
-
Ingår i: Dementia (Switzerland). - 1013-7424. ; 4:1, s. 50-53
-
Tidskriftsartikel (refereegranskat)abstract
- Sweat sodium concentration was estimated with pilocarpine iontophoresis in I 15 women with Alzheimer's disease (AD) and 29 healthy control women. The age ranged from 76 to 96 years with a mean age of 85 years in both groups. The mean sodium concentration of 91 ± 41 mmol/l (n = 11) in the Alzheimer patients was significantly higher than in the control group (62 ± 29 mmol/l, n=27, p=0.0011). 27% of AD patients and 7% of the control women did not respond to stimulation. The impaired sweating in AD patients make them more vulnerable to heat stress. Further studies are needed to reveal whether the neurophysiological mechanism involved is located in the hypothalamus, in cortical projections to the hypothalamus or in postganglionic sympathetic fibers.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To assess the relative validity of two diet assessment methods, an extensive quantitative food frequency questionnaire (method A) and a novel shorter quantitative food frequency questionnaire with a 14 day food record (method B). Design: A randomized prospective cohort study. Setting: General community. Subjects: 206 residents of the town of Malmö, aged between 50-69 years, 101 men and 105 women who completed the methods during one year. Methods: Both diet methods were designed to cover the whole diet and portion sizes were estimated using a booklet with 120 photographs; method A comprised 250 items and method B combined a two-week food record measuring lunch and dinner meals and a shorter 130 item quantitative food frequency questionnaire for average consumption of foods, snacks and beverages during the past year. An 18 day dietary record comprising six 3-day weighed records evenly distributed over one year served as a reference method. Results: Pearson's correlation coefficients varied from 0.25 for fat intake to 0.84 for milk products for method A and from 0.32 for fish to 0.88 for meat for method B. Correlations for most food groups ranged between 0.50-0.80, and were higher for method B. Only small changes were noted after adjustment for energy intake. On average for most food groups categorization of subjects into quartiles, 55% of subjects belonging to the lowest quartile, and 57-59% of those belonging to the highest quartile for method A and B were correctly classified. Conclusion: A combined food record with a quantitative food frequency questionnaire is a better tool for food assessment than an extensive food frequency questionnaire. Sponsorship: This study was supported by the Swedish Medical Research Council (K84-19X-7010-01) and the International Agency for Research on Cancer (Collaborative Research Agreement DEB/85/43).

- Objective: To assess the reproducibility of two diet assessment methods, an extensive quantitative food frequency questionnaire (method A) and a novel shorter quantitative food frequency questionnaire with a 14 day food record (method B). Design: A randomized prospective cohort study. Setting: General community. Subjects: 241 residents of the town of Malmö, aged between 50-69 years, 126 men and 115 women who completed the methods one year apart. Methods: Both diet methods were designed to cover the whole diet and portion sizes were estimated using a booklet with 120 photographs; method A comprised 250 items and method B combined a two-week food record measuring lunch and dinner meals and a shorter 130 item quantitative food frequency questionnaire for average consumption of foods, snacks and beverages during the past year; Results: The percent difference between estimated energy intake one year apart were for men 10.7% for method A and 0.2% for method B, corresponding values for women 13.7% and 1.1%. Method B showed a good agreement between measurements for energy-providing nutrients, micronutrients and major food groups, i.e. meat products, edible fats, milk, fish, fruits and vegetables with correlation coefficients between 0.70-0.90 for women. The percent difference of average intake of edible fat was about 10%. Average energy-adjusted Pearson's correlation coefficients were of the order of 0.50-0.80 for most nutrients including 14 fatty acids. The correlation for the ratio between polyunsaturated and saturated fatty acids were about 0.70 for men and 0.80 for women; Conclusion: A modified diet history method combining a food record and a food frequency questionnaire shows good reproducibiiity. Sponsorship: This study was granted by the Swedish Medical research Council (Grant K 84-19X-7010-1) and by the International Agency for Research on cancer (Collaborative research agreement DEB/85/43).

Tidskriftsartikel (refereegranskat)abstract
- Objective: To describe dietary habits and use of mineral supplements in relation to nutrient recommendations and anaemia. Design: a population-based cohort study. Subjects: 2665 men and 3878 women, born between 1926 and 1945, randomly invited and participating in the prospective 'Malmo Diet and Cancer study' during 1991-1992. Methods: The diet was assessed using a combined 7-day menu book for hot meals, beverages and supplements and a quantitative food frequency questionnaire for other foods. Anaemia was defined as haemoglobin ≤131 g/l for men and ≤115 g/l for women. Results: Intake of mineral supplements were reported by 19% of the men and 31% of the women. Less than 0.2% had intakes of iron and selenium above highest recommended Swedish long-term intakes. The percentage of women with intake below nutrient recommendations were: zinc and selenium (60%); magnesium (35%); calcium (21%) and iron (70%, premenopausal). The corresponding values for men were: zinc, selenium and magnesium (33-47%); calcium and iron (5%). The median contribution of calcium from supplements was less than 110 mg. Supplement users had higher intakes of fish, fruits, vegetables and tea and lower intakes of coffee and meat. The iron intake was correlated to haemoglobin levels, and iron supplementation constituted about 45% of the intake. Three per cent of premenopausal women had anaemia as did less than 2% of postmenopausal women. Conclusion: A substantial number had mineral intake below present recommendations despite supplement use. The nutrient content of some supplements could be improved, especially calcium. Iron supplementation among postmenopausal women and men are questionable.

-
Tidskriftsartikel (refereegranskat)abstract
- Myocardial infarction is a leading cause of death globally but is notoriously difficult to predict. We aimed to identify biomarkers of an imminent first myocardial infarction and design relevant prediction models. Here, we constructed a new case–cohort consortium of 2,018 persons without prior cardiovascular disease from six European cohorts, among whom 420 developed a first myocardial infarction within 6 months after the baseline blood draw. We analyzed 817 proteins and 1,025 metabolites in biobanked blood and 16 clinical variables. Forty-eight proteins, 43 metabolites, age, sex and systolic blood pressure were associated with the risk of an imminent first myocardial infarction. Brain natriuretic peptide was most consistently associated with the risk of imminent myocardial infarction. Using clinically readily available variables, we devised a prediction model for an imminent first myocardial infarction for clinical use in the general population, with good discriminatory performance and potential for motivating primary prevention efforts.

- Plasma concentrations of adrenaline, noradrenaline, aldosterone and plasma renin activity were determined in a selected group of 80-year-old men (N = 41) in good health without clinical signs of cardiovascular disease, and were compared to levels in young healthy males (N = 20, 24-28 years). Plasma adrenaline and noradrenaline concentrations were higher (0.24 median; 25th-75th percentiles 0.16-0.34 nmol/L vs 0.15; 0.11-0.18 nmol/L, p < 0.01 and 2.22; 1.58-3.27 nmol/L vs 1.15; 1.00-1.74 nmol/L, p < 0.001), and plasma renin activity and plasma aldosterone concentration were lower in the old than in the young men (0.65; 0.35-1.04 micrograms/L/1h vs 2.09; 1.23-2.41 micrograms/L/1h, p < 0.001 and 0.12; 0.09-0.19 nmol/L vs 0.38; 0.28-0.54 nmol/L, p < 0.001). In conclusion, increased plasma concentrations of catecholamines and decreased plasma concentration of aldosterone and plasma renin activity in old men, as compared to young men, must be considered when interpreting data of these hormones in elderly men.

Tidskriftsartikel (refereegranskat)abstract
- Background: The objective was to investigate whether socioeconomic differences in fat intake may explain socioeconomic differences in cardiovascular diseases. Methods: The Malm Diet and Cancer Study is a prospective cohort study. The baseline examinations used in the present cross-sectional study were undertaken in 19921994. Dietary habits were assessed using a modified diet history method consisting of a 7-day menu book and a 168-item questionnaire. A subpopulation of 11 837 individuals born 19261945 was investigated. This study examined high fat intake, defined as >35.9 among men and >34.8 among women (25 quartile limit) of the proportion of the non-alcohol energy intake contributed by fat. The subfractions saturated, mono-unsaturated and poly-unsaturated fatty acids and the P:S ratio (polyunsaturated/saturated fatty acids) were analysed in the same way. The uppermost quartile (75) of total and subgroup fat intake was also studied. Socioeconomic differences before and after adjustment for low energy reporting (LER), defined as energy intake below 1.2 x Basal Metabolic Rate, were examined. Results: No socioeconomic differences in fat intake were seen between the SES groups, except for self-employed men, and male and female pensioners. Approximately 20 in most SES groups were LER. The LER and body mass index were strongly related. The SES pattern of fat intake remained unchanged after adjustment for age, country of origin and LER in a logistic regression model. The results for the subfractions of fat and the P:S ratio did not principally differ from the total fat results. Conclusions: This study provides no evidence that fat intake contributes to the inverse socioeconomic differences in cardiovascular diseases.

Tidskriftsartikel (refereegranskat)abstract
- In order to investigate potential selection bias in population-based cohort studies, participants (n = 28098) and non-participants (n = 40807) in the Malmo Diet and Cancer Study (MDCS) were compared with regard to cancer incidence and mortality. MDCS participants were also compared with participants in a mailed health survey with regard to subjective health, socio-demographic characteristics and lifestyle. Cancer incidence prior to recruitment was lower in non-participants, Cox proportional hazards analysis yielded a relative risk (RR) with a 95% confidence interval of 0.95 (0.90-1.00), compared with participants. During recruitment, cancer incidence was higher in non-participants, RR: 1.08 (1.01-1.17). Mortality was higher in non-participants both during, 3.55 (3.13-4.03), and following the recruitment period, 2.21 (2.03-2.41). The proportion reporting good health was higher in the MDCS than in the mailed health survey (where 74.6% participated), but the socio-demographic structure was similar. We conclude that mortality is higher in non-participants than in participants during recruitment and follow-up. It is also suggested that non-participants may have a lower cancer incidence prior to recruitment but a higher incidence during the recruitment period.

- Background and Aims: The optimal extent of mesenteric resection in colon cancer surgery remains elusive. The aim was to assess the impact on perioperative morbidity and oncological outcome depending on the height of central vessel ligation in sigmoid resection for adenocarcinomas. Material and Methods: All cases of stage I–III sigmoid cancers, operated on with locally radical resections (2007–2009), were identified in the Swedish Colorectal Cancer Registry and categorized according to the position of the vascular ligature, that is, ligation of the inferior mesenteric artery, ligation of the superior rectal artery, or ligation of the sigmoid branches. Results: In total, 999 cases were identified and possible to categorize. Although higher ligation level yielded a higher number of lymph nodes, 3- or 5-year overall survival, 5-year disease-free survival, or recurrence rate did not differ between the groups (p = 0.79, p = 0.41, p = 0.67, p = 0.51). No differences in survival were detected after multivariate analysis adjusted for age, sex, T-stage, N-stage, American Society of Anesthesiologists classification, and adjuvant therapy. Conclusion: This large population-based study showed increased lymph node yield but no survival benefit or any decreased recurrence rate by high tie in resection of sigmoid cancer.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To validate a 7-day estimated dietary record routine with standardized portion sizes and household measuring in a clinical setting with the doubly labelled water (DLW) method as the reference method. Design: Energy expenditure was measured with deuterium (2H) and oxygen-18 (18O), and water loss was estimated by 2H dilution as part of the DLW measurements. Energy and water intake was measured with a 7 day dietary record. Setting: Five nursing home wards in Sweden. Subjects: Thirty-one geriatric patients with a mean age of 86y. Inclusion criteria were stable body weight, defined as a maximum change of ± 4% during the last 4 months of ± 2% during the last 2 months and without any acute illness. Results: The mean daily energy intake was 7.2 MJ (1727 kcal) and the mean daily energy expenditure was 6.7 MJ (1595 kcal). The mean daily water intake was 1787 ml and mean daily water loss assessed by labelled water was 1774 ml. Using the dietary record routine, the staff overestimated the patients' energy intake by 8% and water intake from food and beverages by < 1% compared to DLW. Conclusion: The 7 day dietary record routine based on standardized portion sizes and household measuring seems to be a valid method for assessing the intake of energy and fluids by geriatric patients.

Are you sure? : Confidence about the satiating capacity of a food affects subsequent food intake
- 2015
-
Ingår i: Nutrients. - : MDPI AG. - 2072-6643. ; 7:7, s. 5088-5097

Tidskriftsartikel (refereegranskat)abstract
- Expectations about a food’s satiating capacity predict self-selected portion size, food intake and food choice. However, two individuals might have a similar expectation, but one might be extremely confident while the other might be guessing. It is unclear whether confidence about an expectation affects adjustments in energy intake at a subsequent meal. In a randomized cross-over design, 24 subjects participated in three separate breakfast sessions, and were served a low-energy-dense preload (53 kcal/100 g), a high-energy-dense preload (94 kcal/100 g), or no preload. Subjects received ambiguous information about the preload’s satiating capacity and rated how confident they were about their expected satiation before consuming the preload in its entirety. They were served an ad libitum test meal 30 min later. Confidence ratings were negatively associated with energy compensation after consuming the high-energy-dense preload (r = −0.61; p = 0.001). The same relationship was evident after consuming the low-energy-dense preload, but only after controlling for dietary restraint, hunger prior to, and liking of the test meal (p = 0.03). Our results suggest that confidence modifies short-term controls of food intake by affecting energy compensation. These results merit consideration because imprecise caloric compensation has been identified as a potential risk factor for a positive energy balance and weight gain.

Orthostatic hypotension in Alzheimer's disease : Result or cause of brain dysfunction?
- 1999
-
Ingår i: Aging clinical and experimental research. - 0394-9532. ; 11:3, s. 155-160
-
Tidskriftsartikel (refereegranskat)abstract
- In Alzheimer's disease (AD), an association was found between autonomic dysfunction and frontal hypoperfusion in brain during orthostatic testing. To ascertain whether frontal hypoperfusion is dependent on longitudinal effects of hemodynamic disturbances, or contributes to them, we studied the relationship between the presence of orthostatic hypotension (OH) and resting cerebral blood flow (CBF) in late stages of AD. Twelve women with senile dementia of Alzheimer type (SDAT), and 15 non-demented women (mean age 82.6 years, SD 3.8 vs 81.8 years, SD 3.5) were examined with the orthostatic test. Four of 12 patients with SDAT, and 9 controls had OH (defined as systolic blood pressure fall ≥ 20 mmHg). CBF was determined under resting conditions using 600 Mbq 99mTc HMPAO single photon emission computerized tomography (SPECT), and quantified in cortical areas in relation to cerebellum. In patients with SDAT and OH, CBF was lower in frontal and parieto-frontal cortical areas than in SDAT patients without OH. The former group was younger and had a shorter dementia duration. No significant differences in CBF were observed between controls with vs without OH. No differences in SDAT patients with or without OH were observed in the Berger dementia scale or Katz' ADL index. No difference in incidence of symptoms related to autonomic disturbances (diarrhea, obstipation, dysphagia, vertigo) was observed in either the SDAT or control group with regard to OH presence. We conclude that during the course of AD, OH can contribute to frontal brain changes and may exacerbate the disease. The further involvement of frontal dysfunction in aggravating blood pressure dysregulation in the elderly is discussed.

No difference in body weight decrease between a low-glycemic-index and a high-glycemic-index diet but reduced LDL cholesterol after 10-wk ad libitum intake of the low-glycemic-index diet
- 2004

Tidskriftsartikel (refereegranskat)abstract
- Background: The role of glycemic index (GI) in appetite and body-weight regulation is still not clear. Objective: The objective of the study was to investigate the long-term effects of a low-fat, high-carbohydrate diet with either low glycemic index (LGI) or high glycemic index (HGI) on ad libitum energy intake, body weight, and composition, as well as on risk factors for type 2 diabetes and ischemic heart disease in overweight healthy subjects. Design: The study was a 10-wk parallel, randomized, intervention trial with 2 matched groups. The LGI or HGI test foods, given as replacements for the subjects’ usual carbohydrate-rich foods, were equal in total energy, energy density, dietary fiber, and macronutrient composition. Subjects were 45 (LGI diet: n = 23; HGI diet: n = 22) healthy overweight [body mass index (in kg/m2): 27.6 ± 0.2] women aged 20–40 y. Results: Energy intake, mean (± SEM) body weight (LGI diet: –1.9 ± 0.5 kg; HGI diet: –1.3 ± 0.3 kg), and fat mass (LGI diet: –1.0 ± 0.4 kg; HGI diet: –0.4 ± 0.3 kg) decreased over time, but the differences between groups were not significant. No significant differences were observed between groups in fasting serum insulin, homeostasis model assessment for relative insulin resistance, homeostasis model assessment for ß cell function, triacylglycerol, nonesterified fatty acids, or HDL cholesterol. However, a 10% decrease in LDL cholesterol (P < 0.05) and a tendency to a larger decrease in total cholesterol (P = 0.06) were observed with consumption of the LGI diet as compared with the HGI diet. Conclusions: This study does not support the contention that low-fat LGI diets are more beneficial than HGI diets with regard to appetite or body-weight regulation as evaluated over 10 wk. However, it confirms previous findings of a beneficial effect of LGI diets on risk factors for ischemic heart disease. Key Words: Obesity • fat mass • energy intake • type 2 diabetes • ischemic heart disease • cholesterol • triacylglycerol • glucose • insulin

- The purpose of the present study was to test the reliability and validity of a new electrical impedance method for estimating body composition in 35 healthy persons and patients in different sex and age groups, and to obtain basal data on the size of different body composition compartments in elderly individuals in health and disease. The reliability studies showed no significant differences with the new method in intraindividual comparisons before and after changing the positions of the electrodes, drinking of water, and overnight fasting, as well as at a double estimation on 2 consecutive days. The results with this method are compared to results from measurements of total body potassium and total body water, and from a four-compartment model technique using total body potassium and total body water. We conclude that the method has an acceptable reliability and validity and should be of great value not only in field studies but also in clinical practice. Data on body composition with the electrical impedance method are obtained from 147 individuals in different groups, namely healthy females, 80-81-year-old males, female patients from a nursing home, and patients of both sexes from a day care unit.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: Study formal and informal care of community-living older people in the Swedish National study of Aging and Care (SNAC). Design: Cross-sectional, population based cohort. Setting: Three areas in Sweden: Municipality of Nordanstig, Stockholm and Skane County. Participants: 3,338 persons >= 72 years. Measurements: Patterns and amounts of informal and formal care by cognition and area of residence. Results: 73% received no care; 14% formal care; and 17% informal care (7% received both). In the whole study population, including those who used no care, individuals in small municipalities received 9.6 hours of informal care/month; in mid-size municipalities, 6.6; and in urban areas, 5.6. Users of informal care received 33.1 hours of informal care/month in small municipalities, 54.6 in mid-size municipalities and 36.1 in urban areas. Individuals with cognitive impairment received 14.1 hours of informal care/month, 2.7 times more than people with no/slight impairment. In the whole study population, individuals in small municipalities received an average of 3.2 hours of formal care/month; in mid-size municipalities 1.4; and in urban areas, 2.6. Corresponding figures for formal care users were 29.4 hours in small municipalities, 13.6 in mid-size municipalities and 16.7 in urban areas. Formal care users received 7.1 hours, and informal care users, 5.9 hours for each hour/month received by people in the study population as a whole. Conclusions: More informal than formal care was provided. Informal care is more frequent in small municipalities than urban areas and for those with than without cognitive impairment. The relationship between data on the whole population and the data on users or care indicates that population-based data are needed to avoid overestimates of care.
