1.	Cederholm, Tommy, et al. (författare) ESPEN guidelines on definitions and terminology of clinical nutrition 2017 Ingår i: Clinical Nutrition. - 0261-5614 .- 1532-1983. ; 36:1, s. 49-64 Tidskriftsartikel (refereegranskat)abstract BackgroundA lack of agreement on definitions and terminology used for nutrition-related concepts and procedures limits the development of clinical nutrition practice and research.ObjectiveThis initiative aimed to reach a consensus for terminology for core nutritional concepts and procedures.MethodsThe European Society of Clinical Nutrition and Metabolism (ESPEN) appointed a consensus group of clinical scientists to perform a modified Delphi process that encompassed e-mail communication, face-to-face meetings, in-group ballots and an electronic ESPEN membership Delphi round.ResultsFive key areas related to clinical nutrition were identified: concepts; procedures; organisation; delivery; and products. One core concept of clinical nutrition is malnutrition/undernutrition, which includes disease-related malnutrition (DRM) with (eq. cachexia) and without inflammation, and malnutrition/undernutrition without disease, e.g. hunger-related malnutrition. Over-nutrition (overweight and obesity) is another core concept. Sarcopenia and frailty were agreed to be separate conditions often associated with malnutrition. Examples of nutritional procedures identified include screening for subjects at nutritional risk followed by a complete nutritional assessment. Hospital and care facility catering are the basic organizational forms for providing nutrition. Oral nutritional supplementation is the preferred way of nutrition therapy but if inadequate then other forms of medical nutrition therapy, i.e. enteral tube feeding and parenteral (intravenous) nutrition, becomes the major way of nutrient delivery.ConclusionAn agreement of basic nutritional terminology to be used in clinical practice, research, and the ESPEN guideline developments has been established. This terminology consensus may help to support future global consensus efforts and updates of classification systems such as the International Classification of Disease (ICD). The continuous growth of knowledge in all areas addressed in this statement will provide the foundation for future revisions.
2.	Skoglund, Elisabeth, et al. (författare) Functional improvements to 6 months of physical activity are not related to changes in size or density of multiple lower-extremity muscles in mobility-limited older individuals 2022 Ingår i: Experimental Gerontology. - : Elsevier BV. - 0531-5565 .- 1873-6815. ; 157 Tidskriftsartikel (refereegranskat)abstract Older adults are encouraged to engage in multicomponent physical activity, which includes aerobic and muscle-strengthening activities. The current work is an extension of the Vitality, Independence, and Vigor in the Elderly 2 (VIVE2) study - a 6-month multicenter, randomized, placebo-controlled trial of physical activity and nutritional supplementation in community dwelling 70-year-old seniors. Here, we examined whether the magnitude of changes in muscle size and quality differed between major lower-extremity muscle groups and related these changes to functional outcomes. We also examined whether daily vitamin-D-enriched protein supplementation could augment the response to structured physical activity. Forty-nine men and women (77 ± 5 yrs) performed brisk walking, muscle-strengthening exercises for the lower limbs, and balance training 3 times weekly for 6 months. Participants were randomized to daily intake of a nutritional supplement (20 g whey protein + 800 IU vitamin D), or a placebo. Muscle cross-sectional area (CSA) and radiological attenuation (RA) were assessed in 8 different muscle groups using single-slice CT scans of the hip, thigh, and calf at baseline and after the intervention. Walking speed and performance in the Short Physical Performance Battery (SPPB) were also measured. For both CSA and RA, there were muscle group × time interactions (P < 0.01). Significant increases in CSA were observed in 2 of the 8 muscles studied, namely the knee extensors (1.9%) and the hip adductors (2.8%). For RA, increases were observed in 4 of 8 muscle groups, namely the hip flexors (1.1 HU), hip adductors (0.9 HU), knee extensors (1.2 HU), and ankle dorsiflexors (0.8 HU). No additive effect of nutritional supplementation was observed. While walking speed (13%) and SPPB performance (38%) improved markedly, multivariate analysis showed that these changes were not associated with the changes in muscle CSA and RA after the intervention. We conclude that this type of multicomponent physical activity program results in significant improvements in physical function despite relatively small changes in muscle size and quality of some, but not all, of the measured lower extremity muscles involved in locomotion.

Adamsson, Viola (författare) A Healthy Nordic Diet and Cardiometabolic Risk Factors : Intervention Studies with Special Emphasis on Plasma Lipoproteins 2013 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract A healthy diet is important in the prevention of cardiovascular disease (CVD). Several risk factors, modifiable by diet, are involved in the development of CVD, e.g. hyperlipidaemia, hyperglycaemia, insulin resistance, obesity and hypertension. Little data however exist on diets composed of foods originating from the Nordic countries, and their potential to reduce CVD risk.This thesis aimed to investigate whether an ad libitum healthy Nordic diet (ND), either provided as a whole diet, or as a prudent breakfast (PB) alone, could influence CVD risk factors in healthy, mildly hypercholesterolemic men and women. Another aim was to describe the nutrient and food composition of the ND, both by using self-reported data and serum biomarkers of dietary fat quality.The primary clinical outcome measure was LDL-cholesterol, and other cardiometabolic risk factors were secondary outcomes.Two parallel, randomised, controlled intervention studies were conducted in free-living subjects. Clinical and dietary assessments were performed at baseline and at the end of dietary interventions. All foods were provided to subjects randomised to ND, whereas only breakfast items were supplied to subjects randomised to PB. Control groups followed their habitual diet/breakfast.Compared with controls, ND reduced body weight and improved several CVD risk factors including LDL-cholesterol, insulin sensitivity and blood pressure. Several, but not all effects were probably partly mediated by diet-induced weight loss. ND accorded with Nordic nutrition recommendations and was defined as “a plant-based diet, where animal products are used sparingly as side dishes”. Compared with average Swedish diet, ND was high in dietary fibre, but low in sodium, meat, high-fat dairy products, sweets and alcohol. A decreased intake of saturated fat and increased intake of n-3 PUFA during ND was partly reflected in serum lipids. Eating a PB without other dietary changes did not improve lipid or glucose metabolism, but decreased markers of visceral fat and inflammation, without influencing body weight.This thesis suggests that a whole ND, but not PB alone, promotes weight loss and improves multiple CVD risk factors in healthy subjects after 6 weeks. These results suggest that ND could have a potential role in the prevention of cardiometabolic diseases.
4.	Adamsson, Viola, et al. (författare) Influence of a healthy Nordic diet on serum fatty acid composition and associations with blood lipoproteins : results from the NORDIET study 2014 Ingår i: Food & Nutrition Research. - : SNF Swedish Nutrition Foundation. - 1654-6628 .- 1654-661X. ; 58, s. 24114- Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract Background: The fatty acid (FA) composition of serum lipids is related to the quality of dietary fat. The aim of this study was to investigate the effects of a healthy Nordic diet (ND) on the FA composition of serum cholesterol esters (CE-FA) and assess the associations between changes in the serum CE-FA composition and blood lipoproteins during a controlled dietary intervention.Methods: The NORDIET trial was a six-week randomised, controlled, parallel-group dietary intervention study that included 86 adults (53±8 years) with elevated low-density lipoprotein cholesterol LDL-C. Serum CE-FA composition was measured using gas chromatography. Diet history interviews were conducted, and daily intake was assessed using checklists.Results: Food and nutrient intake data indicated that there was a reduction in the fat intake from dairy and meat products and an increase in the consumption of fatty fish with the ND, decreasing the levels of saturated fatty acids (SFA) in the diet, slightly decreasing the levels of monounsaturated fatty acids (MUFA) and moderately increasing the levels of polyunsaturated fatty acids (PUFA). Concomitantly, the levels of CE-SFA 14:0, 15:0 and 18:0, but not 16:0, decreased during the ND, and these changes differed from those observed in the control diet group (p<0.01). In contrast, serum 22:6n-3 increased during the ND compared with the control diet (p<0.01). The changes in CE-SFA 14:0, 15:0 and 18:0 during the intervention correlated positively with those in LDL-C, HDL-C, LDL-C/HDL-C, ApoA1 and ApoB (p<0.01), whereas the changes in CE-PUFA 22:6n-3 were negatively correlated with changes in the corresponding serum lipids.Conclusions: The decreased intake of saturated fat and increased intake of n-3 PUFA in a healthy Nordic diet are partly reflected by changes in the serum CE-FA composition, which are associated with an improved serum lipoprotein pattern.
5.	Adamsson, Viola, et al. (författare) What is a healthy Nordic diet? : Foods and nutrients in the NORDIET study 2012 Ingår i: Food & Nutrition Research. - Bålsta : SNF Swedish Nutrition Foundation. - 1654-6628 .- 1654-661X. ; 56, s. 18189- Tidskriftsartikel (refereegranskat)abstract Background: A healthy Nordic diet (ND), a diet based on foods originating from the Nordic countries, improves blood lipid profile and insulin sensitivity and lowers blood pressure and body weight in hypercholesterolemic subjects. Objective: To describe and compare food and nutrient composition of the ND in relation to the intake of a Swedish reference population (SRP) and the recommended intake (RI) and average requirement (AR), as described by the Nordic nutrition recommendations (NNR). Design: The analyses were based on an estimate of actual food and nutrient intake of 44 men and women (mean age 53 +/- 8 years, BMI 26 +/- 3), representing an intervention arm receiving ND for 6 weeks. Results: The main difference between ND and SRP was the higher intake of plant foods, fish, egg and vegetable fat and a lower intake of meat products, dairy products, sweets and desserts and alcoholic beverages during ND (p<0.001 for all food groups). Intake of cereals and seeds was similar between ND and SRP (p>0.3). The relative intake of protein, fat and carbohydrates during ND was in accordance with RI. Intake of all vitamins and minerals was above AR, whereas sodium intake was below RI. Conclusions: When compared with the food intake of an SRP, ND is primarily a plant-based diet. ND represents a balanced food intake that meets the current RI and AR of NNR 2004 and has a dietary pattern that is associated with decreased morbidity and mortality.

7.	Al-Ani, Amer, et al. (författare) Low bone mineral density and fat free mass in young and middle-aged patients with a femoral neck fracture 2015 Ingår i: European Journal of Clinical Investigation. - : Wiley. - 0014-2972 .- 1365-2362. ; 45:8, s. 800-806 Tidskriftsartikel (refereegranskat)abstract BackgroundReduced bone mineral density (BMD) together with muscle wasting and dysfunction, that is sarcopenia, emerges as a risk factor for hip fracture. The aim of this study was to examine body composition and BMD and their relationship with trauma mechanisms in young and middle-aged patients with femoral neck fracture.Materials and methodsAltogether, 185 patients with femoral neck fracture aged 20–69 were included. BMD, body composition and fat-free mass index (FFMI) were determined by dual-X-ray absorptiometry (DXA), and trauma mechanisms were registered.ResultsNinety per cent of the whole study population had a femoral neck BMD below the mean for age. In the young patients (< 50 years), 27% had a Z-score of BMD ≤ −2 SD. More than half of the middle-aged patients (50–69 years) had osteopenia, that is T-score −1 to −2·5, and 35% had osteoporosis, that is T-score < −2·5, at the femoral neck. Patients with low-energy trauma, sport injury or high-energy trauma had a median standardised BMD of 0·702, 0·740 vs. 0·803 g/cm2 (P = 0·03), and a median FFMI of 15·9, 17·7 vs. 17·5 kg/m2 (P < 0·001), respectively. FFMI < 10th percentile of an age- and gender-matched reference population was observed in one-third.ConclusionsA majority had low BMD at the femoral neck, and one-third had reduced FFMI (i.e. sarcopenia). Patients with fracture following low-energy trauma had significantly lower femoral neck BMD and FFMI than patients with other trauma mechanisms. DXA examination of both BMD and body composition could be of value especially in those with low-energy trauma.

(författare) Does Rehabilitation Matter in Patients With Femoral Neck Fracture and Cognitive Impairment? : A Prospective Study of 246 Patients 2010 Ingår i: Archives of Physical Medicine and Rehabilitation. - : Elsevier BV. - 0003-9993 .- 1532-821X. ; 91:1, s. 51-57 Tidskriftsartikel (refereegranskat)abstract Objective: To identify factors associated with preserved walking ability and Katz activities of daily living (ADLs) index at 4-month and 12-month follow-up in cognitively impaired patients with femoral neck fracture. Design: Population-based cohort study. Setting: A multicenter study of the Stockholm Hip Fracture Group including 4 university hospitals. Participants: Consecutive patients (N=246) with femoral neck fracture, older than 65 years (mean, 84y; 72% women) with cognitive impairment (known dementia or low [0-2 points] score) in Short Portable Mental Status Questionnaire [0-10 points]) and able to walk before the fracture. Interventions: Not applicable. Main Outcome Measure: Walking ability and ADLs index at 4-month and 12-month follow-up. Results: Significant predictors of preserved walking ability at 12-month follow-up were discharge to rehabilitation unit (odds ratio [OR]=2.83: confidence interval [CI], 1.1-7.26; P=.03) and walking ability before the fracture (OR=8.98; Cl, 3.52-22.93; P<.001), while type of surgery was not (P=.197). Analyses were adjusted for age, sex, American Society of Anesthesiologists score, fracture type, and surgical method. Corresponding predictors of preserved Katz ADLs index at 12-month follow-up, after adjustment for age and sex, were discharge to rehabilitation unit (OR=5.33; Cl, 1.44-19.65: P=.012) and ADLs index before fracture (OR=2.5; Cl. 1.8-3.5: P<.001), while type of surgery was not (P=.376). Conclusions: Discharge to rehabilitation unit, a factor we can influence, was associated with preserved walking ability and ADLs index in cognitively impaired patients with hip fracture.

11.	Alsharari, Zayed, et al. (författare) Association between carbohydrate intake and fatty acids in the de novo lipogenic pathway in serum phospholipids and adipose tissue in a population of Swedish men 2020 Ingår i: European Journal of Nutrition. - : Springer Science and Business Media LLC. - 1436-6207 .- 1436-6215. ; 59:5, s. 2089-2097 Tidskriftsartikel (refereegranskat)abstract Purpose Fatty acid composition in blood and adipose tissue (AT) is a useful biomarker of dietary fat quality. However, circulating saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) have been proposed to also reflect carbohydrate-induced de novo lipogenesis (DNL) and stearoyl-CoA desaturase (SCD) activity. We aimed to test the hypothesis that high carbohydrate intake is related to SFA and MUFA in serum or AT in a Swedish population. Methods Fatty acid composition was measured in serum phospholipids (PL) and AT by gas chromatography in 63-year-old men (n = 299). Carbohydrate and alcohol intake was assessed (validated 7-day food records) in relation to total SFA, 16:0 (palmitate), 16:1 (palmitoleate), and estimated SCD activity (16:1n-7/16:0-ratio) in serum PL and in AT, respectively. Results Total carbohydrate intake was inversely associated with 16:0 in PL (P = 0.005), independently of BMI. Disaccharides were non-linearly (restricted cubic splines) and weakly associated with 16:1 and SCD activity in PL (nonlinear trend,P <= 0.02) but not AT. Carbohydrate intake and SCD expression were not associated (P >= 0.08,n = 81). Alcohol intake was, however, linearly associated with 16:0 in PL (P < 0.001), and with 16:1 (P < 0.001) and SCD activity (P <= 0.005) in both PL and AT. Conclusions Higher carbohydrate intake from sugar-rich foods or beverages was not clearly reflected by higher SFA or SCD activity in serum PL or AT. Alcohol was, however, associated with higher SFA and MUFA.
12.	Alsharari, Zayed, et al. (författare) Association between carbohydrate intake and fatty acids in the de novo lipogenic pathwayin serum phospholipids and adipose tissue among 63-year old men Annan publikation (övrigt vetenskapligt/konstnärligt)abstract AbstractBackground: Fatty acid composition in blood and adipose tissue is useful to reflect dietary fatquality, although the utility of even-chain saturated fatty acids (SFA) and monounsaturated fatty acids (MUFA) has been debated. Since SFA also can be produced via de novo lipogenesis (DNL), and desaturated to MUFA, it has been proposed that these fatty acids may reflect carbohydrate-induced DNL. We aimed to test the hypothesis that high carbohydrate intake, especially sugars, is related to SFA and MUFA in serum and adipose tissue.Methods: Validated 7-day food records were collected and fatty acid composition in serum phospholipids (PL) and adipose tissue (AT) were measured in 63-year-old men (n=299). Stearoyl-CoA desaturate (SCD) activities in AT and PL were estimated by the palmitoleic acid (16:1) to palmitic acid (16:0) ratio. Associations of dietary carbohydrate, disaccharides, monosaccharides, carbohydrate-to-fiber ratio, and alcohol with the sum of even-chain SFA, 16:0, 16:1, and SCD activity were assessed using linear regression models with and without adjustment for BMI. Non-linear trends were evaluated using restricted cubic splines. In a subsample (n=81) with RNA measured in AT biopsies, associations of dietary carbohydrate and alcohol with SCD gene expression were assessed using linear regression models.Results: In BMI-adjusted models, intake of carbohydrates was inversely associated with palmitic acid in PL (P=0.005). Disaccharide intake was non-linearly associated with 16:1 and SCD activity in PL (P for nonlinear trend ≤0.02), with the lowest values observed in the mid tertile. Alcohol intake was linearly associated with 16:0 in PL (P<0.001) and with 16:1 (P<0.001) and SCD activity (P ≤0.005) in AT. Alcohol intake was non-linear associated (P≤0.02) with 16:1 and SCD activity in PL; with initially stable levels at lower intakes that rapidly increased at intakes above median. In the subsample, we found no associations between carbohydrate intake and SCD gene expression (P ≥0.08).Conclusion: In this Swedish population, we found no evidence to suggest that higher carbohydrate intake or sugar-rich foods or beverages is reflected by higher SFA in PL and AT.Instead, alcohol was consistently associated with higher SFA and MUFA.
13.	Alsharari, Zayed, et al. (författare) CarbohydrateIntake and Abdominal Obesity in Swedish Men Annan publikation (övrigt vetenskapligt/konstnärligt)abstract ABSTRACTBackground/Objectives: Associations between carbohydrates, particularly simple sugar and starch, and abdominal anthropometric measures appears controversial. However, the role of dietary carbohydrate intake in obesity and abdominal obesity has been debated, and few studies have been conducted in Nordic populations. We aim to examine the associations between carbohydrate quantity and quality, and anthropometric measures in Swedish men.Subjects/Methods: A cross-sectional investigation of 301 63-year-old men was conducted. Six men were excluded due to missing data on dietary intake and anthropometric measures, leaving 295 men for the present study. Healthy men were recruited from the Swedish 60YO cohort of men and women who had a health screening between 1997 to 1999. Carbohydrate and alcohol intake were assessed by a 7-days food record. The examination included anthropometric measurements (e. g., weight, BMI, WC, WHR, and SAD), fasting blood samples, and a comprehensive questionnaire. Spearman rank correlation and linear regression models were performed to assess relations between dietary intakes and anthropometric measures. Intakes of macronutrients were energy-adjusted according to the residual method. Logistic regression models were used to calculate odds ratios (OR) and 95% CI for abdominal obesity per intake tertiles.Results: Intakes of carbohydrate, monosaccharide, fibers, and fruits and vegetables correlated negatively with anthropometric measures of overall obesity (BMI) and AO (WC, WHR, and SAD). Total carbohydrate intake was significantly inversely associated with WHR and SAD. Likewise, monosaccharide intake was significantly associated with lower BMI, WC, WHR, and SAD. In contrast, alcohol intake was significantly associated with weight, BMI, WC, and SAD (Table 4). Alcohol intake was associated with AO (P for linear trend 0.002). Men in the highest tertile of alcohol intake were almost three times as likely to have AO compared to the men in the lowest tertile of intake, OR (95% CI): 2.93 (1.40-6.16). There was no evidence of non-linear association between the macronutrients and AO.Conclusion: In this Swedish population of older men, higher intakes of total carbohydrates and monosaccharides were associated a more favorable body fat distribution and lower abdominal adiposity. Men with higher alcohol intake were more likely to have AO as compared with a lower intake.
14.	Alsharari, Zayed, et al. (författare) Comparison of a 21-item food questionnaire with a 7-day dietary registration andbiomarkers of fat intake in a Swedish cohort of 60-year-old adults. Annan publikation (övrigt vetenskapligt/konstnärligt)abstract AbstractPurpose. To evaluate a 21-item food frequency questionnaire (FFQ) in men participating in alarge cohort of Swedish 60-year-old adults (60YO).Methods. A self-reported FFQ (including 21 qualitative and semi-quantitative questions) was completed by >2000 men as part of a detailed baseline examination. A subsample of 301 men was included in a subsequent study in which detailed dietary habits were determined by a 7-day food record. Spearman rank correlations (r) and weighted Kappa (Kw) statistics were used to compare food intake categories in FFQ and 7-day food record. Furthermore, fatty acid (FA) composition in serum cholesteryl esters, assessed concurrent with the FFQ completion, was used to evaluate intakes of specific fat-rich foods from the FFQ.Results. We found good agreement between FFQ and food records for the reported intake ofalcohol (r=0.72, Kw=0.51), margarine (r=0.60, Kw=0.33), and fruit (r=0.49, Kw=0.31), reasonably good agreement for total fish (r=0.25, Kw=0.23), and egg (r=0.35, Kw=0.28), but poor agreement for other food groups such as bread, cheese, vegetables and cookies. In addition, serum proportions of long-chain n-3 polyunsaturated FAs and pentadecanoic acid were significantly higher in men with greater intakes of fish and cheese, respectively.Conclusion. In this evaluation of a short FFQ against 7-d food records and serum biomarkers of fat intake we found that the FFQ reasonably well reflected the intake of certain food groups (e.g. alcohol, fish, and margarine), but performed less accurate for other food groups. Firm and overallconclusions on validity are confined by the time-lag between the test and the reference method.
15.	Alsharari, Zayed (författare) Dietary Intake, Fatty Acid Biomarkers, and Abdominal Obesity : Population-Based Observational Studies 2017 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract The aim of this thesis was to investigate the associations between fatty acid (FA) biomarkers, carbohydrate intake, and abdominal obesity (AO) and related anthropometric measures in a population-based cohort of men and women in Stockholm County. The overall hypothesis was that dietary fat quality assessed by serum and adipose tissue FA composition, and dietary intake of especially carbohydrates is associated with AO. FA composition was assessed by liquid gas chromatography, and AO was measured as waist circumference (WC), waist hip ratio (WHR) and sagittal abdominal diameter (SAD). Dietary intake was assessed by 7-day food records.Papers I, II, III, and IV were all observational studies based on a Swedish population in Stockholm County (n=5460). A sub-cohort of only men (n=301) was included in Papers II, III, and IV.In Paper I, serum proportions of the polyunsaturated FA (PUFA), linoleic acid (LA) (18:2n6), was inversely associated with AO in both men and women, whereas a positive association was observed between the saturated FA (SFA), palmitic acid (PA) (16:0) and AO measures. These findings support recent interventional studies suggesting that a higher relative intake of PUFA (LA) from vegetable oils as compared with 16:0 is associated with decreased abdominal adiposity.In Paper II, we investigated whether biomarkers of dietary fat quality were related to the corresponding FA intake from fat-rich foods reported in a short food frequency questionnaire (FFQ). Serum proportions of the long-chain n-3 PUFAs eicosapentaenoic acid (EPA) and docosahexanoic acid (DHA) were higher among men with higher total fish intake. Serum LA was higher among men who reported a consumption of more than 5 g/d of margarine. Absolute agreement between intakes assessed with FFQ of 60YO and 7-day food record of "Kost och Metabola syndromet"/"Diet and the Metabolic syndrome" (KOMET) was highest for alcohol, total fish, and eggs. Weighted Kappa statistics revealed the strongest agreement for alcohol, margarine, and fruits.In Paper III, carbohydrate intake was inversely associated with 16:0 in serum phospholipids (PL). Disaccharide and alcohol intake was positively and non-linearly associated with palmitoleic acid (16:1) and stearoyl-CoA-desaturase (SCD) activity in PL. Alcohol was consistently associated with higher SFA and monounsaturated FA (MUFA).Results of Paper IV indicated that total carbohydrate intake was inversely associated with measures of AO and central fat distribution, WHR and SAD, respectively. Likewise, monosaccharide intake was associated with lower AO. In contrast, alcohol intake was associated with AO prevalence and all anthropometric measurements.In conclusion, serum SFA (palmitic acid) was positively associated with AO, whereas n-6 PUFA (linoleic acid) was associated with lower AO. High intake of total carbohydrate and monosaccharides were associated with lower AO. Overall, these results support a beneficial role on adiposity of diets that are higher in polyunsaturated fat (vegetable oils) and total carbohydrates compared with saturated fat.

17.	Alsharari, Zayed, et al. (författare) Serum Fatty Acids, Desaturase Activities and Abdominal Obesity - A Population-Based Study of 60-Year Old Men and Women 2017 Ingår i: PLOS ONE. - : PUBLIC LIBRARY SCIENCE. - 1932-6203. ; 12:1 Tidskriftsartikel (refereegranskat)abstract Abdominal obesity is a key contributor of metabolic disease. Recent trials suggest that dietary fat quality affects abdominal fat content, where palmitic acid and linoleic acid influence abdominal obesity differently, while effects of n-3 polyunsaturated fatty acids are less studied. Also, fatty acid desaturation may be altered in abdominal obesity. We aimed to investigate cross-sectional associations of serum fatty acids and desaturases with abdominal obesity prevalence in a population-based cohort study. Serum cholesteryl ester fatty acids composition was measured by gas chromatography in 60-year old men (n = 1883) and women (n = 2015). Cross-sectional associations of fatty acids with abdominal obesity prevalence and anthropometric measures (e.g., sagittal abdominal diameter) were evaluated in multivariable-adjusted logistic and linear regression models, respectively. Similar models were employed to investigate relations between desaturase activities (estimated by fatty acid ratios) and abdominal obesity. In logistic regression analyses, palmitic acid, stearoyl-CoA- desaturase and Delta 6-desaturase indices were associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals) for highest versus lowest quartiles were 1.45 (1.19-1.76), 4.06 (3.27-5.05), and 3.07 (2.51-3.75), respectively. Linoleic acid, alpha-linolenic acid, docohexaenoic acid, and Delta 5-desaturase were inversely associated with abdominal obesity; multivariable-adjusted odds ratios (95% confidence intervals): 0.39 (0.32-0.48), 0.74 (0.61-0.89), 0.76 (0.62-0.93), and 0.40 (0.33-0.49), respectively. Eicosapentaenoic acid was not associated with abdominal obesity. Similar results were obtained from linear regression models evaluating associations with different anthropometric measures. Sex-specific and linear associations were mainly observed for n3-polyunsaturated fatty acids, while associations of the other exposures were generally non-linear and similar across sexes. In accordance with findings from short-term trials, abdominal obesity was more common among individuals with relatively high proportions of palmitic acid, whilst the contrary was true for linoleic acid. Further trials should examine the potential role of linoleic acid and its main dietary source, vegetable oils, in abdominal obesity prevention.

We tested whether two ACEi (captopril and enalapril), differing in a thiol group, protected human umbilical vein endothelial cells (HUVEC) from cytotoxicity induced by polymorphonuclear neutrophils (PMN) in vitro, when cells were activated by tumour necrosis factor-α (TNFα) or the arachidonate derivative lipoxin-A4 (LXA4), using separate cytotoxicity pathways. When 51Cr labelled HUVEC were treated with captopril (0–500 μm) or enalapril (0–100 μm) for 2 h and then activated by TNFα (100 ng/ml) for 24 h, a significant, dose-dependent reduction of 51Cr release was observed. Similarly, captopril reduced 51Cr release when LXA4 (0.1 μm) was used to stimulate PMN for 4 h. Among previously defined mechanisms of significance for the cytotoxic reaction, expression of ICAM-1, but not intracellular Ca2+ changes in PMN or PMN adherence to HUVEC, were reduced by ACEi treatment. Moreover, both ACEi inhibited HUVEC surface expression of TNFα receptor I (but not II). Thus, these ACEi, particularly captopril, interfere with PMN-induced cytotoxicity for endothelial cells by modulating pro-inflammatory surface receptors, which is a novel effect that might be explored for further therapeutic approaches.

Still, little is known about our dietary habits' contribution to exposure variability.Objective: The aim of this study was to assess circulating levels of environmental contaminants in relation to predefined dietary patterns in an elderly Swedish population.Methods: Dietary data and serum concentrations of environmental contaminants were obtained from 844 70-year-old Swedish subjects (50% women) in the Prospective Investigation of the Vasculature in Uppsala Seniors (PIVUS) study. Dietary data from 7-day food records was used to assess adherence to a Mediterranean-like diet, a low carbohydrate-high protein diet and the WHO dietary recommendations. Circulating levels of 6 polychlorinated biphenyl markers, 3 organochlorine pesticides, 1 dioxin and 1 polybrominated diphenyl ether, the metals cadmium, lead, mercury and aluminum and serum levels of bisphenol A and 4 phthalate metabolites were investigated in relation to dietary patterns in multivariate linear regression models.Results: A Mediterranean-like diet was positively associated with levels of several polychlorinated biphenyls (118, 126, 153, and 209), trans-nonachlor and mercury. A low carbohydrate-high protein diet was positively associated with polychlorinated biphenyls 118 and 153, trans-nonachlor, hexachlorobenzene and p, p'-dichlorodiphenyldichloroethylene, mercury and lead. The WHO recommended diet was negatively related to levels of dioxin and lead, and borderline positively to polychlorinated biphenyl 118 and trans-nonachlor.Conclusion: Dietary patterns were associated in diverse manners with circulating levels of environmental contaminants in this elderly Swedish population. Following the WHO dietary recommendations seems to be associated with a lower burden of environmental contaminants.

However, studies on dietary pattern and prostate cancer are scarce. Food intake data in the Uppsala Longitudinal Study of Adult Men cohort was determined by 7-day food records. Adherence to a modified Mediterranean Diet Score (mMDS) and a low carbohydrate-high protein (LCHP) score were grouped as low, medium, or high in the whole study population (n = 1,044) and in those identified as adequate reporters of energy intake (n = 566), respectively. Prostate cancer risk was analyzed with Cox proportional hazard regression (median follow-up 13years) and competing risk of death was considered. There were no associations between dietary patterns and prostate cancer (n = 133) in the whole study population. Among adequate reporters the mMDS was not associated with prostate cancer (n = 72). The LCHP score was inversely related to prostate cancer in adequate reporters, adjusted hazard ratios; 0.55 (0.32-0.96) for medium and 0.47 (0.21-1.04) for high compared to low adherent participants (P-for-trend 0.04). Risk relations were not attributable to competing risk of death. In this study, a LCHP diet was associated with lower prostate cancer incidence. Relations emerged in adequate reporters, underscoring the importance of high-quality dietary data.

The aim of this study was to identify and characterise dietary patterns in Swedish adults using data from the national dietary survey Riksmaten adults 2010–11 (952 women, 788 men). Principal component analyses were used and two patterns were identified in both sexes: a healthy pattern loading positively on vegetables, fruits, fish and seafood, and vegetable oils, and negatively on refined bread and fast food, and a Swedish traditional pattern loading positively on potatoes, meat and processed meat, full-fat milk products, sweet bakery products, sweet condiments and margarine. In addition, a light-meal pattern was identified in women with positive loadings on fibre-rich bread, cheese, rice, pasta and food grain dishes, substitute products for meat and dairy products, candies and tea. The healthy pattern was positively correlated to dietary fibre (r 0·51–0·58) and n-3 (r 0·25–0·31) (all P<0·0001), and had a higher nutrient density of folate, vitamin D and Se. The Swedish traditional and the light-meal pattern were positively correlated to added sugar (r 0·20–0·25) and the Swedish traditional also to SFA (r 0·13–0·21) (all P<0·0001); both patterns were in general negatively correlated to micronutrients. Dietary pattern scores were associated with, for example, age, physical activity, education and income. In conclusion, we identified three major dietary patterns among Swedish adults. The patterns can be further used for examining the association between whole diet and health outcomes.

Findings Grade 1 vs. grade 2 low muscle mass (LMM) thresholds were 1.189 and 0.954 kg/BMI vs. 1.049 and 0.823 kg/BMI in males and females, respectively. Message While validation studies are needed to evaluate their predictive ability, our approach presented here seems applicable and the cut-off values acceptable for use until population-specific values in different populations or global generic cut-offs are identified. Purpose Among approaches to adjust skeletal muscle mass (SMM) for body size, adjustment for body mass index (BMI) correlated better with functional measures. To enhance applicability of GLIM criteria, we report grade 1 and grade 2 reduced muscle mass cut-offs for SMM adjusted by BMI. Methods 301 young, healthy adults involving students, patient relatives and staff working in the university hospital were included. SMM was estimated by bio-impedance analysis (BIA). SMM index (BMI) [SMMI(BMI)] was calculated as SMM/BMI. Grade 1 low muscle mass (LMM) was defined as "mean young SMMI(BMI)-one standard deviation" and grade 2 LMM as "mean young SMMI(BMI)-two standard deviations". Results Mean age was 26.5 +/- 4.6 (62.1% male). Grade 1 vs grade 2 LMM thresholds were 1.189 and 0.954 kg/BMI vs 1.049 and 0.823 kg/BMI in males and females, respectively. Conclusion This is the first report identifying stage 1 and stage 2 LMM thresholds for SMMI adjusted by BMI. Studies are needed to evaluate their predictive validity.

Methodological issues have also contributed to incomplete agreement, as different approaches, techniques and potential surrogate measures inevitably lead to partly different conclusions. As a consequence: 1) awareness of sarcopenia and implementation of diagnostic procedures in clinical practice have been limited; 2) patient identification and evaluation of therapeutic strategies is largely incomplete. Significant progress has however recently occurred after major diagnostic algorithms have been developed, with common features and promising perspectives for growing consensus. At the same time, the need for further refinement of the sarcopenia concept has emerged, to address its increasingly recognized clinical heterogeneity. This includes potential differential underlying mechanisms and clinical features for age-and disease-driven sarcopenia, and the emerging challenge of sarcopenia in persons with obesity. Here, we will review existing algorithms to diagnose sarcopenia, and major open methodological issues to assess skeletal muscle mass and function under different clinical conditions, in order to highlight similarities and differences. Potential for consensus on sarcopenia diagnosis as well as emerging new challenges will be discussed.

The GLIM approach is based on the assessment of three phenotypic (weight loss, low body mass index, and low skeletal muscle mass) and two etiologic (low food intake and presence of disease with systemic inflammation) criteria, with diagnosis confirmed by any combination of one phenotypic and one etiologic criterion fulfilled. Assessment of muscle mass is less commonly performed than other phenotypic malnutrition criteria, and its interpretation may be less straightforward, particularly in settings that lack access to skilled clinical nutrition practitioners and/or to body composition methodologies. In order to promote the widespread assessment of skeletal muscle mass as an integral part of the GLIM diagnosis of malnutrition, the GLIM consortium appointed a working group to provide consensus-based guidance on assessment of skeletal muscle mass. When such methods and skills are available, quantitative assessment of muscle mass should be measured or estimated using dual-energy x-ray absorptiometry, computerized tomography, or bioelectrical impedance analysis. For settings where these resources are not available, then the use of anthropometric measures and physical examination are also endorsed. Validated ethnic-and sex-specific cutoff values for each measurement and tool are recommended when available. Measurement of skeletal muscle function is not advised as surrogate measurement of muscle mass. However, once malnutrition is diagnosed, skeletal muscle function should be investigated as a relevant component of sarcopenia and for complete nutrition assessment of persons with malnutrition.

Acute respiratory complications that require intensive care unit (ICU) management are a major cause of morbidity and mortality in COVID-19 patients. Among other important risk factors for severe COVID-19 outcomes, obesity has emerged along with undernutrition-malnutrition as a strong predictor of disease risk and severity. Obesity-related excessive body fat may lead to respiratory, metabolic and immune derangements potentially favoring the onset of COVID-19 complications. In addition, patients with obesity may be at risk for loss of skeletal muscle mass, reflecting a state of hidden malnutrition with a strong negative health impact in all clinical settings. Also importantly, obesity is commonly associated with micronutrient deficiencies that directly influence immune function and infection risk. Finally, the pandemic-related lockdown, deleterious lifestyle changes and other numerous psychosocial consequences may worsen eating behaviors, sedentarity, body weight regulation, ultimately leading to further increments of obesity-associated metabolic complications with loss of skeletal muscle mass and higher non-communicable disease risk. Therefore, prevention, diagnosis and treatment of malnutrition and micronutrient deficiencies should be routinely included in the management of COVID-19 patients in the presence of obesity; lockdown-induced health risks should also be specifically monitored and prevented in this population. In the current document, the European Society for Clinical Nutrition and Metabolism (ESPEN) aims at providing clinical practice guidance for nutritional management of COVID-19 patients with obesity in various clinical settings.

Obesity poses unprecedented individual, social, and multidisciplinary medical challenges by increasing the risk for metabolic diseases, chronic organ failures, and cancer as well as complication rates in the presence of acute disease conditions. Whereas reducing excess adiposity remains the fundamental pathogenic treatment for obese individuals, complex metabolic and lifestyle abnormalities as well as weight reduction therapies per se may also compromise the ability to preserve muscle function and mass, especially when chronic disease co-exists with obesity. Emerging evidence indicates that low muscle mass and quality have a strong negative prognostic impact in obese individuals and may lead to frailty, disability, and increased morbidity and mortality. Awareness of the importance of skeletal muscle maintenance in obesity is however low among clinicians and scientists. The term 'sarcopenic obesity' has been proposed to identify obesity with low skeletal muscle function and mass, but its utilization is largely limited to the aging patient population, and consensus on its definition and diagnostic criteria remains insufficient. Knowledge on prevalence of sarcopenic obesity in various clinical conditions and patient subgroups, on its clinical impacts in patient risk stratification, and on effective prevention and treatment strategies remain therefore dramatically inadequate. In particular, optimal dietary options and medical nutritional support strategies to preserve muscle mass in obese individuals remain largely undefined. The European Society for Clinical Nutrition and Metabolism (ESPEN) and the European Association for the Study of Obesity (EASO) recognize and indicate obesity with altered body composition due to low skeletal muscle function and mass (sarcopenic obesity) as a scientific and clinical priority for researchers and clinicians. ESPEN and EASO therefore call for coordinated action aimed at reaching consensus on its definition, diagnostic criteria, and optimal treatment with particular regard to nutritional therapy. We are convinced that achievement of these goals has a strong potential to reduce the burden of morbidity and mortality in the rapidly increasing obese patient population.

(författare) Evidence-Based Recommendations for Optimal Dietary Protein Intake in Older People : A Position Paper From the PROT-AGE Study Group 2013 Ingår i: Journal of the American Medical Directors Association. - : Elsevier BV. - 1525-8610 .- 1538-9375. ; 14:8, s. 542-559 Tidskriftsartikel (refereegranskat)abstract New evidence shows that older adults need more dietary protein than do younger adults to support good health, promote recovery from illness, and maintain functionality. Older people need to make up for age-related changes in protein metabolism, such as high splanchnic extraction and declining anabolic responses to ingested protein. They also need more protein to offset inflammatory and catabolic conditions associated with chronic and acute diseases that occur commonly with aging. With the goal of developing updated, evidence-based recommendations for optimal protein intake by older people, the European Union Geriatric Medicine Society (EUGMS), in cooperation with other scientific organizations, appointed an international study group to review dietary protein needs with aging (PROT-AGE Study Group). To help older people (>65 years) maintain and regain lean body mass and function, the PROT-AGE study group recommends average daily intake at least in the range of 1.0 to 1.2 g protein per kilogram of body weight per day. Both endurance-and resistance-type exercises are recommended at individualized levels that are safe and tolerated, and higher protein intake (ie, >= 1.2 g/kg body weight/d) is advised for those who are exercising and otherwise active. Most older adults who have acute or chronic diseases need even more dietary protein (ie, 1.2-1.5 g/kg body weight/d). Older people with severe kidney disease (ie, estimated GFR <30 mL/min/1.73m(2)), but who are not on dialysis, are an exception to this rule; these individuals may need to limit protein intake. Protein quality, timing of ingestion, and intake of other nutritional supplements may be relevant, but evidence is not yet sufficient to support specific recommendations. Older people are vulnerable to losses in physical function capacity, and such losses predict loss of independence, falls, and even mortality. Thus, future studies aimed at pinpointing optimal protein intake in specific populations of older people need to include measures of physical function.

Nutritional supplementation could positively influence aspects of sarcopenia and thereby prevent mobility disability. Objective: To test the hypothesis that a specific oral nutritional supplement can result in improvements in measures of sarcopenia. Design: A multicenter, randomized, controlled, double-blind, 2 parallel-group trial among 380 sarcopenic primarily independent-living older adults with Short Physical Performance Battery (SPPB; 0-12) scores between 4 and 9, and a low skeletal muscle mass index. The active group (n = 184) received a vitamin D and leucine-enriched whey protein nutritional supplement to consume twice daily for 13 weeks. The control group (n = 196) received an iso-caloric control product to consume twice daily for 13 weeks. Primary outcomes of handgrip strength and SPPB score, and secondary outcomes of chair-stand test, gait speed, balance score, and appendicular muscle mass (by DXA) were measured at baseline, week 7, and week 13 of the intervention. Results: Handgrip strength and SPPB improved in both groups without significant between-group differences. The active group improved more in the chair-stand test compared with the control group, between-group effect (95% confidence interval): -1.01 seconds (-1.77 to -0.19), P = .018. The active group gained more appendicular muscle mass than the control group, between-group effect: 0.17 kg (0.004-0.338), P = .045. Conclusions: This 13-week intervention of a vitamin D and leucine-enriched whey protein oral nutritional supplement resulted in improvements in muscle mass and lower-extremity function among sarcopenic older adults. This study shows proof-of-principle that specific nutritional supplementation alone might benefit geriatric patients, especially relevant for those who are unable to exercise. These results warrant further investigations into the role of a specific nutritional supplement as part of a multimodal approach to prevent adverse outcomes among older adults at risk for disability.

OLE participants were randomized to receive daily 1 or 2 servings of WP-MND (21 g protein, 3 g leucine, 10 mu g vitD and 500 mg calcium per serving). Gastro-intestinal tolerability, kidney function and serum levels of calcidiol, parathyroid hormone (PTH) and calcium were evaluated at week 0, 13 and 26.Results and discussion In response to the high daily protein intake (median1.5; IQR: 1.3, 1.7 g/kg BW/day), the estimated glomerular filtration rate (eGFR) increased in the test group during the RCT (p = 0.013). The same trend was observed for those participants with moderate chronic kidney disease. During OLE no eGFR change was observed in any of the groups. Serum calcidiol and calcium reached a plateau after 13-week WP-MND supplementation. As expected, PTH significantly changed in the opposite direction, decreasing during RCT in the test group (T vs C:p < 0.001) and during OLE in former control groups. During RCT, 20/366 participants with normal baseline calcidiol reached levels >= 100 nmol/L (T:n = 18; C:n = 2) and 6 developed albumin-corrected calcium levels > 2.55 mmol/L (T:n = 3; C:n = 3), without associated adverse events.Conclusion A 6 months intervention with up to 2 servings of WP-MND did neither result in kidney function deterioration nor symptoms of vitamin D or calcium toxicity. The product was overall well tolerated.

In October 2019 a Scientific Symposium was organized by the European Society for Clinical Nutrition and Metabolism (ESPEN) in Vienna, Austria, to celebrate this historical landmark, looking at what is currently known about the estimation and measurement of energy expenditure.Methods: Current evidence was discussed during the symposium, including the scientific basis and clinical knowledge, and is summarized here to assist with the estimation and measurement of energy requirements that later translate into energy prescription.Results: In most clinical settings, the majority of predictive equations have low to moderate performance, with the best generally reaching an accuracy of no more than 70%, and often lead to large errors in estimating the true needs of patients. Generally speaking, the addition of body composition measurements did not add to the accuracy of predictive equations. Indirect calorimetry is the most reliable method to measure energy expenditure and guide energy prescription, but carries inherent limitations, greatly restricting its use in real life clinical practice.Conclusions: While the limitations of predictive equations are clear, their use is still the mainstay in clinical practice. It is imperative to recognize specific patient populations for whom a specific equation should be preferred. When available, the use of indirect calorimetry is advised in a variety of clinical settings, aiming to avoid under-as well as overfeeding.

However, muscle mass and functions are not routinely assessed. Sarcopenia is defined as skeletal muscle loss and dysfunction in aging and chronic diseases. Inactivity, inflammation, age-related factors, anorexia and unbalanced nutrition affect changes in skeletal muscle. Mechanisms are difficult to distinguish in individual subjects due to the multifactorial character of the condition. Sarcopenia includes both muscle loss and dysfunction which induce contractile impairment and metabolic and endocrine abnormalities, affecting whole-body metabolism and immune/inflammatory response. There are different metabolic trajectories for muscle loss versus fat changes in aging and chronic diseases. Appetite regulation and physical activity affect energy balance and changes in body fat mass. Appetite regulation by inflammatory mediators is poorly understood. In some patients, inflammation induces anorexia and fat loss in combination with sarcopenia. In others, appetite is maintained, despite activation of systemic inflammation, leading to sarcopenia with normal or increased BMI. Inactivity contributes to sarcopenia and increased fat tissue in aging and diseases. At the end of the metabolic trajectories, cachexia and sarcopenic obesity are paradigms of the two patient categories. Pre-cachexia and cachexia are observed in patients with cancer, chronic heart failure or liver cirrhosis. Sarcopenic obesity and sarcopenia with normal/increased BMI are observed in rheumatoid arthritis, breast cancer patients with adjuvant chemotherapy and in most of patients with COPD or chronic kidney disease. In these conditions, sarcopenia is a powerful prognostic factor for morbidity and mortality, independent of BMI.

The SOP is valid and obligatory for all future ESPEN-sponsored guideline projects aiming to generate high-quality guidelines on a regular basis. The SOP aims to facilitate the preparation of guideline projects, to streamline the consensus process, to ensure quality and transparency, and to facilitate the dissemination and publication of ESPEN guidelines. To achieve this goal, the ESPEN Guidelines Editorial board (GEB) has been established headed by two chairmen. The GEB will support and supervise the guideline processes and is responsible for the strategic planning of ESPEN guideline activities. Key elements of the SOP are the generation of well-built clinical questions according to the PICO system, a systemic literature search, a classification of the selected literature according to the SIGN evidence levels providing an evidence table, and a clear and straight-forward consensus procedure consisting of online voting's and a consensus conference. Only experts who meet the obligation to disclosure any potential conflict of interests and who are not employed by the Industry can participate in the guideline process. All recommendations will be graded according to the SIGN grading and novel outcome models besides biomedical endpoints. This approach will further extent the leadership of ESPEN in creating up-to-date and suitable for implementation guidelines and in sharing knowledge on malnutrition and clinical nutrition.

(författare) Towards a multidisciplinary approach to understand and manage obesity and related diseases 2017 Ingår i: Clinical Nutrition. - : Elsevier BV. - 0261-5614 .- 1532-1983. ; 36:4, s. 917-938 Forskningsöversikt (refereegranskat)abstract Overnutrition and sedentary lifestyle result in overweight or obesity defined as abnormal or excessive fat accumulation that may impair health. According to the WHO, the worldwide prevalence of obesity nearly doubled between 1980 and 2008. In 2008, over 50% of both men and women in the WHO European Region were overweight, and approximately 23% of women and 20% of men were obese. Comprehensive diagnostic and therapeutic approaches should include nutritional treatment to favor the best metabolic and nutritional outcome, as well as to induce potential disease-specific benefits from selected nutritional regimens. Obesity is usually accompanied by an increased muscle mass. This might explain why obesity, under particular circumstances such as cancer or high age, might have protective effects, a phenomenon named the 'obesity paradox'. However, loss of muscle mass or function can also occur, which is associated with poor prognosis and termed 'sarcopenic obesity'. Therefore, treatment recommendations may need to be individualized and adapted to co-morbidities. Since obesity is a chronic systemic disease it requires a multidisciplinary approach, both at the level of prevention and therapy including weight loss and maintenance. In the present personal review and position paper, authors from different disciplines including endocrinology, gastroenterology, nephrology, pediatrics, surgery, geriatrics, intensive care medicine, psychology and psychiatry, sports medicine and rheumatology, both at the basic science and clinical level, present their view on the topic and underline the necessity to provide a multidisciplinary approach, to address this epidemic.

40.	Bjermo, Helena, 1981- (författare) Dietary Fatty Acids and Inflammation : Observational and Interventional Studies 2011 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Dietary fat quality influences the risk of type 2 diabetes and cardiovascular disease. A low-grade inflammation is suggested to contribute to the disease development, often accompanied by obesity. Whereas n-3 polyunsaturated fatty acids (PUFA) have been considered anti-inflammatory, n-6 PUFA have been proposed to act pro-inflammatory. Saturated fatty acids (SFA) act pro-inflammatory in vitro. This thesis aimed to investigate effects of different fatty acids on low-grade inflammation in observational and interventional studies. In Paper I and II, fatty acid composition in serum cholesterol esters was used as objective marker of dietary fat quality and related to serum C-reactive protein (CRP) and other circulating inflammatory markers in two population-based cohorts, conducted in middle-aged men and elderly men and women, respectively. In Paper III and IV, the impact of diets differing in fat quality on inflammation and oxidative stress was investigated in randomised controlled studies, in subjects with metabolic syndrome and abdominal obesity. In Paper I and II, a low proportion of linoleic acid (18:2 n-6) in serum was associated with higher CRP concentrations, indicating that a low intake of vegetable fats may be related to low-grade inflammation. High CRP concentrations were also associated with high proportions of palmitoleic (16:1) and oleic (18:1) acids and high stearoyl coenzymeA desaturase index, possibly reflecting altered fat metabolism and/or high SFA intake in this population. When comparing two high-fat diets rich in either saturated or monounsaturated fat, and two low-fat diets with or without long-chain n-3 PUFA supplementation during 12 weeks (Paper III), no differences in inflammation or oxidative stress markers were observed. Moreover, a 10-week intervention (Paper IV) with high linoleic acid intake showed no adverse effects on inflammation or oxidative stress. Instead, interleukin-1 receptor antagonist and tumor necrosis factor receptor-2 decreased after linoleic acid intake compared with a diet high in SFA. The results in this thesis indicate that dietary n-6 PUFA found in vegetable fats is associated with lower inflammation marker levels, and to some extent reduces systemic inflammation when compared with SFA. Supplementation of n-3 PUFA did not exert any systemic anti-inflammatory effects, maybe due to a relatively low dose.

Increased dietary n-6 PUFAs have, however, also been proposed to promote inflammation-a yet unproven theory. OBJECTIVE: We investigated the effects of PUFAs on liver fat, systemic inflammation, and metabolic disorders. DESIGN: We randomly assigned 67 abdominally obese subjects (15% had type 2 diabetes) to a 10-wk isocaloric diet high in vegetable n-6 PUFA (PUFA diet) or SFA mainly from butter (SFA diet), without altering the macronutrient intake. Liver fat was assessed by MRI and magnetic resonance proton (1H) spectroscopy (MRS). Proprotein convertase subtilisin/kexin type-9 (PCSK9, a hepatic LDL-receptor regulator), inflammation, and adipose tissue expression of inflammatory and lipogenic genes were determined. RESULTS: A total of 61 subjects completed the study. Body weight modestly increased but was not different between groups. Liver fat was lower during the PUFA diet than during the SFA diet [between-group difference in relative change from baseline; 16% (MRI; P < 0.001), 34% (MRS; P = 0.02)]. PCSK9 (P = 0.001), TNF receptor-2 (P < 0.01), and IL-1 receptor antagonist (P = 0.02) concentrations were lower during the PUFA diet, whereas insulin (P = 0.06) tended to be higher during the SFA diet. In compliant subjects (defined as change in serum linoleic acid), insulin, total/HDL-cholesterol ratio, LDL cholesterol, and triglycerides were lower during the PUFA diet than during the SFA diet (P < 0.05). Adipose tissue gene expression was unchanged. CONCLUSIONS: Compared with SFA intake, n-6 PUFAs reduce liver fat and modestly improve metabolic status, without weight loss. A high n-6 PUFA intake does not cause any signs of inflammation or oxidative stress. Downregulation of PCSK9 could be a novel mechanism behind the cholesterol-lowering effects of PUFAs.

(författare) Nutrient Intake and Its Association with Appendicular Total Lean Mass and Muscle Function and Strength in Older Adults: A Population-Based Study 2024 Ingår i: NUTRIENTS. - : MDPI. - 2072-6643. ; 16:4 Tidskriftsartikel (refereegranskat)abstract Treatment options for sarcopenia are currently limited, and primarily rely on two main therapeutic approaches: resistance-based physical activity and dietary interventions. However, details about specific nutrients in the diet or supplementation are unclear. We aim to investigate the relationship between nutrient intake and lean mass, function, and strength. Data were derived from the Gothenburg H70 birth cohort study in Sweden, including 719,70-year-olds born in 1944 (54.1% females). For independent variables, the diet history method (face-to-face interviews) was used to estimate habitual food intake during the preceding three months. Dependent variables were gait speed (muscle performance), hand grip strength (muscle strength), and the appendicular lean soft tissue index (ALSTI). Linear regression analyses were performed to analyze the relationship between the dependent variables and each of the covariates. Several nutrients were positively associated with ALSTI, such as polyunsaturated fatty acids (DHA, EPA), selenium, zinc, riboflavin, niacin equivalent, vitamin B12, vitamin D, iron, and protein. After correction for multiple comparisons, there were no remaining correlations with handgrip and gait speed. Findings of positive correlations for some nutrients with lean mass suggest a role for these nutrients in maintaining muscle volume. These results can be used to inform clinical trials to expand the preventive strategies and treatment options for individuals at risk of muscle loss and sarcopenia.

(författare) Assessment of muscle mass, muscle strength and physical performance in clinical practice : An international survey 2016 Ingår i: European Geriatric Medicine. - : Elsevier BV. - 1878-7649 .- 1878-7657. ; 7:3, s. 243-246 Tidskriftsartikel (refereegranskat)abstract Introduction: Several tools are available for the assessment of muscle mass, muscle strength and physical performance in clinical research. However, few data are available on the usage of these tools in clinical practice.Methods: This study aimed to assess their usage by means of a large online international survey. Since sarcopenia is a specific condition where the assessment of muscle mass, muscle strength and physical performance is important, the survey also assessed the tools used for the diagnosis of this geriatric syndrome.Results: The survey was completed by 255 clinicians from 55 countries across 5 continents. Among these clinicians with geriatrics, rheumatology and endocrinology as major fields of interest, 53.3% assess muscle mass in daily practice, 54.5% muscle strength and 71.4% physical performance. However, the tools used are very different and no single tool is used by all clinicians. The tools and the cut-off values used by clinicians to diagnose sarcopenia are also heterogeneous.Conclusion: Because some tools used for the assessment of muscle mass, muscle strength or physical performance in daily practice are less validated than others, a greater awareness from the clinicians of the importance of using appropriate tools is needed.

Our objective was to assess how practitioners measure the geriatric syndrome of frailty in their daily routine.Methods: An online survey was sent to national geriatric societies affiliated to the European Union Geriatric Medicine Society (EUGMS) and to members of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO).Results: A total of 388 clinicians from 44 countries answered to the survey. Most of them were medical doctors (93%), and their primary field of practice was geriatrics (83%). Two hundred and five clinicians (52.8%) always assessed frailty in their daily practice, 38.1% reported to "sometimes" measure it, and 9.1% never assess it. A substantial proportion of clinicians (64.9%) diagnose frailty using more than one instrument. The most widely used tool was the gait speed test, adopted by 43.8% of the clinicians, followed by clinical frailty scale (34.3%), the SPPB test (30.2%), the frailty phenotype (26.8%) and the frailty index (16.8%).Conclusion: A variety of tools is used to assess frailty of older patients in clinical practice highlighting the need for standardisation and guidelines.
45.	Burman, Maria, 1983- (författare) Malnutrition and obesity among older adults, assessed by Mini Nutritional Assessment and the body mass index, respectively : prevalence and associations with mortality and urinary tract infection 2021 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract INTRODUCTION: Malnutrition and obesity are health concerns among older (aged ≥ 65 years) adults, but the combination of them have not been studied thoroughly nor have they been thoroughly investigated in very old (aged ≥ 85 years) adults. The aims of this thesis were to investigate the prevalence, trends in prevalence and associations with mortality of malnutrition and obesity, assessed by Mini Nutritional Assessment (MNA) and the body mass index (BMI), respectively, and to examine the combined effects of these conditions on mortality. Malnutrition as a risk factor for urinary tract infection (UTI) was also investigated. MATERIAL AND METHODS: The studies reported on in papers I and II were conducted with data from the Umeå85+/Gerontological Regional Database study, a population-based study of cohorts of very old adults. Data from all four Swedish cohorts (2000–2002, 2005–2007, 2010–2012 and 2015–2017), and from the 2000–2002 and 2005–2007 Swedish cohorts and a 2005–2006 Finnish cohort, respectively, were used. In the paper I study, trends in the prevalence of malnutrition (by MNA score) and obesity (by BMI) were investigated across cohorts. In the paper II study, the associations of MNA scores and BMI with 5-year mortality were investigated. The study reported on in paper III was conducted with data from the Senior Alert national quality registry; associations of Mini Nutritional Assessment–Short Form (MNA-SF) scores, BMI and 2-year mortality in older adults living in residential care facilities in Sweden were investigated. The study reported on in paper IV was conducted with data from the Frail Older People–Activity and Nutrition and Umeå Dementia and Exercise studies; risk factors for UTI among older adults in residential care facilities were investigated. RESULTS: In the paper I study, mean BMI increased between 2000–2002 and 2015–2017 and the prevalence of obesity were 13.4% and 18.3%, respectively; the prevalences of underweight were 7.6% and 3.0%, respectively. Mean MNA scores increased between 2000–2002 and 2010–2012 and were slightly lower in 2015–2017. The prevalence of malnutrition according to MNA scores in the four cohorts were 12.2%, 6.4%, 5.1% and 8.7%, respectively, and the prevalence of at risk thereof were 31.8%–37.2%. In the paper II study, 13.3% of participants were malnourished, and 40.3% at risk thereof according to MNA scores, and malnutrition was more common among women than men. Twenty-five percent of the population had BMIs ≥28.0 kg/m2. Of those with malnutrition according to MNA scores, 17.4% had BMIs ≥ 24.7 kg/m2; of those with good nutritional status according to MNA scores, 13.8% had BMIs < 22.2 kg/m2. Compared to malnutrition according to MNA, lesser mortality was found in individuals with good nutritional status. Compared to individuals with BMI <22.2 kg/m2, lesser mortality was found in those with BMI ≥28.0 kg/m2. In the paper III study, 14.6% of the population was malnourished, and 45.0% at risk of malnutrition according to MNA-SF scores and 16.0% were obese. Compared to individuals with good nutritional status, greater mortality was found in those with malnutrition according to MNA-SF. Mortality was greater among underweight than among normal-weight participants and lesser among participants with obesity, including severe obesity. Higher BMIs were also associated with reduced mortality in subgroups defined by MNA-SF scores. In the paper IV study, malnutrition according to MNA scores was not a risk factor for UTI in the whole sample or in women. In men, the MNA score was associated with UTI in univariate analysis. CONCLUSIONS: The results of this thesis highlight the importance of nutritional screening in older adults in residential care facilities and in very old adults, since malnutrition risk was common and associated with greater mortality among these populations. Malnutrition according to MNA was not a clear risk factor for UTI in older adults living in residential care facilities. Time trends indicated an increasing prevalence of obesity whereas no change in nutritional status according to MNA was observed among very old adults, although these trends need further investigation. The results also confirmed that higher BMIs were beneficial for survival in these populations, and in the residential care population this seems to apply also for BMIs reflecting severe obesity. Finally, in the residential care population, regardless of nutritional status according to MNA-SF, higher BMIs were associated with better survival.

These long-term effects are not well described, since most studies have short follow-ups. The aim of this study was to investigate clinical outcome by performance -based functional tests, hand grip strength, and hip function in different subgroups. The secondary aim was to study surgical complications, bone mineral density (BMD) and occurrence of sarcopenia 10 years after a FNF. Patients and methods: A prospective multicenter study with a 10-year follow-up of patients aged 20- 69 years with a FNF treated with internal fixation (IF). Five-times sit-to-stand test (5TSST), 4-m walking speed test, hand grip strength (HGS) and Harris Hip Score (HHS) were performed.A radiographic examination of the hip was performed and re-operations were registered. Bone min-eral density (BMD) at the hip, spine and total body composition were assessed with dual energy x-ray absorptiometry (DXA). Present sarcopenia was determined by the combination of reduced functional per-formance and low fat-free mass index (FFMI).Results: A total of 58 patients were included. 5TSTS was normal in 45% of the patients and old age was associated with poorer performance ( p < 0.001). 76% of the study population had a normal speed gait and likewise, old age ( p = 0.005) and walking aids ( p = 0.001) were associated with poor performance. HGS was normal in 82% of the men and 64% of the women. HHS showed that 85% had a good/excellent function. A major re-operation was performed in 34% of the patients with displaced FNF and in 20% of patients with non-displaced FNF. 74% displayed osteopenia and 12% osteoporosis. 17% of the men and 38% of the women had sarcopenia.Interpretation: The majority of patients less than 70 years of age with a FNF treated with IF, had normal functional tests, muscle strength and a good hip function ten years post-operatively. However, one in ten had osteoporosis, and one third was sarcopenic which indicate the importance of encouraging regular muscle preserving resistance training after hip fracture.(c) 2022 The Authors.
