- From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions.

- Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities(.)(1,2) This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity(3-6). Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to 2017. We show that, contrary to the dominant paradigm, more than 55% of the global rise in mean BMI from 1985 to 2017-and more than 80% in some low- and middle-income regions-was due to increases in BMI in rural areas. This large contribution stems from the fact that, with the exception of women in sub-Saharan Africa, BMI is increasing at the same rate or faster in rural areas than in cities in low- and middle-income regions. These trends have in turn resulted in a closing-and in some countries reversal-of the gap in BMI between urban and rural areas in low- and middle-income countries, especially for women. In high-income and industrialized countries, we noted a persistently higher rural BMI, especially for women. There is an urgent need for an integrated approach to rural nutrition that enhances financial and physical access to healthy foods, to avoid replacing the rural undernutrition disadvantage in poor countries with a more general malnutrition disadvantage that entails excessive consumption of low-quality calories.

- Context: Cell death-inducing DFFA-like effector A (CIDEA) could be a potential target for the treatment of obesity via the modulation of metabolic rate, based on the findings that CIDEA inhibits the brown adipose tissue uncoupling process in rodents. Objective: To investigate the putative link between CIDEA and basal metabolic rate in humans, and to further elucidate the role of CIDEA in human obesity. Design: We have explored CIDEA gene expression in adipose tissue in two different human studies: A cross-sectional and population-based study assessing body composition and metabolic rate (Mölndal Metabolic study, n=92), and a longitudinal intervention-study of obese subjects treated with a very low calorie diet (VLCD study, n=24). Results: The CIDEA gene was predominantly expressed in adipocytes as compared to other human tissues. CIDEA gene expression in adipose tissue was inversely associated with basal metabolic rate independently of body composition, age and gender (p=0.014). VLCD induced an increase in adipose tissue CIDEA expression (p<0.0001) with a subsequent decrease in response to refeeding (p<0.0001). Reduced CIDEA gene expression was associated with a high body fat content (p<0.0001) and with high insulin levels (p<0.01). No dysregulation of CIDEA expression was observed in individuals with the metabolic syndrome when compared with BMI-matched controls. In a separate sample of VLCD-treated subjects (n=10), uncoupling protein 1 expression was reduced during diet (p=0.0026) and inversely associated with CIDEA expression (p=0.0014). Conclusion: The findings are consistent with the concept that CIDEA plays a role in adipose tissue energy expenditure.

- Members of the cell death-inducing DFF45-like effector (CIDE) gene family have been shown to regulate lipid metabolism. In this article, we report that the third member of the human CIDE family, CIDEC, is down-regulated in response to a reduced caloric intake. The down-regulation was demonstrated by microarray and real-time polymerase chain reaction analysis of subcutaneous adipose tissue in 2 independent studies on obese patients undergoing treatment with a very low calorie diet. By analysis of CIDEC expression in 65 human tissues, we conclude that human CIDEC is predominantly expressed in subcutaneous adipocytes. Together, these observations led us to investigate the effect of decreased CIDEC expression in cultured 3T3-L1 adipocytes. Small interfering RNA-mediated knockdown of CIDEC resulted in an increased basal release of nonesterified fatty acids, decreased responsiveness to adrenergic stimulation of lipolysis, and increased oxidation of endogenous fatty acids. Thus, we suggest that CIDEC is a regulator of adipocyte lipid metabolism and may be important for the adipocyte to adapt to changes in energy availability.

- Context: There is considerable individual variation in the clinical response to growth hormone (GH) replacement therapy in GH deficient (GHD) adults. Useful predictors of treatment response are lacking. Objective: To assess the influence of the exon 3-deleted (d3-GHR) and full-length (fl-GHR) GH receptor isoforms on the response to GH replacement therapy in adults with severe GHD. Design, Patients: 124 adult GHD patients (79 men, median age 50 years) were studied before and after 12 months of GH therapy. GHD patients were divided into those bearing fl/fl alleles (Group 1) and those bearing at least one d3-GHR allele (Group 2), and the genotype was related to the effects of GH therapy on IGF-I levels and total body fat (BF). Intervention: GH dose was individually titrated to obtain normal serum IGF-I levels. Main Outcome Measures: GHR genotype was determined by PCR amplification, IGF-I levels by immunoassay, and BF by a four-compartment model. Results: Seventy-two (58%) patients had fl/fl genotype and were classified as Group 1, while 52 (42%) had at least one d3-GHR allele and were classified as Group 2 (40 were heterozygous and 12 were homozygous). At baseline, there were no significant differences in the study groups. Changes in IGF-I and BF after 12 months of GH treatment did not differ significantly between the two genotype groups. Conclusion: The presence of d3-GHR allele did not influence the response to GH replacement therapy in our cohort of adults with severe GHD.

Tidskriftsartikel (refereegranskat)abstract
- Being taller is associated with enhanced longevity, and higher education and earnings. We reanalysed 1472 population-based studies, with measurement of height on more than 18.6 million participants to estimate mean height for people born between 1896 and 1996 in 200 countries. The largest gain in adult height over the past century has occurred in South Korean women and Iranian men, who became 20.2 cm (95% credible interval 17.522.7) and 16.5 cm (13.319.7) taller, respectively. In contrast, there was little change in adult height in some sub-Saharan African countries and in South Asia over the century of analysis. The tallest people over these 100 years are men born in the Netherlands in the last quarter of 20th century, whose average heights surpassed 182.5 cm, and the shortest were women born in Guatemala in 1896 (140.3 cm; 135.8144.8). The height differential between the tallest and shortest populations was 19-20 cm a century ago, and has remained the same for women and increased for men a century later despite substantial changes in the ranking of countries.

- PURPOSE: Rectal cancer is the most common reason for a person to undergo ostomy surgery. The aim of this study was to assess concerns and health-related quality of life (HRQOL) before surgery and during the first 6 months following ostomy surgery in the presence of rectal cancer. SUBJECTS AND SETTINGS: The sample comprised 57 patients at a university hospital in Gothenburg, Sweden. Their median age was 66 years (range, 30-87); 35 men and 22 women participated in the study. METHODS: Participants prospectively answered questionnaires preoperatively, and at 1, 3, and 6 months postoperatively.Concerns were assessed using the rating form of the Inflammatory Bowel Disease Patient Concerns, and HRQOL was evaluated using the 36-Item Short Form Health Survey. Results were compared with population norms. RESULTS: Participants expressed concerns associated with developing cancer, being a burden on others, and related to the uncertain nature of disease. Health-related quality of life scores dropped significantly in 6 of 8 domains when preoperative scores were compared to those obtained 1 month postoperatively, but scores improved at 6 months. There were significant differences between preoperative study group scores and population norms on physical and emotional role function, social function, and for mental health domains. Significant differences persisted when population norms were compared to study group scores 6 months following surgery on all these domains except mental health. Participants identified good relations with significant others, social and leisure activities, psychological issues, and health as important for maintaining QOL. Obstacles to maintaining QOL included fatigue, pain, illness-induced limitations in life, and worries over what their new life would entail. CONCLUSION: Surgical management of rectal cancer raises concerns and profoundly impairs QOL during the first several postoperative months. © 2010 Wound, Ostomy and Continence Nurses Society.

The Prevalence of Ostomy-related Complications 1 Year after Ostomy Surgery: A Prospective, Descriptive, Clinical Study
- 2016

Tidskriftsartikel (refereegranskat)abstract
- Despite advancements in the creation and care of stomas, ostomy and peristomal skin complications are common immediately following surgery as well as in the months and years thereafter. A prospective study to determine the prevalence of ostomy and peristomal skin complications and the influence of ostomy configuration on such complications was conducted 1 year after ostomy surgery among all patients at a university hospital in Sweden. All participants received regular (10 to 14 days post discharge, 6 weeks, 3 months, 6 months, and 1 year post surgery) ostomy follow-up care by a wound ostomy continence (WOC) nurse. All consecutive elective and emergency patients who had undergone surgery to create a colostomy (end colostomy), end ileostomy, or loop ileostomy were eligible to participate. Patients who were reoperated during their first year post-surgery, patients with a urostomy, and patients with double ostomies were excluded from the study. Patient data collected included age, gender, diagnosis, elective or emergency surgery, open or laparoscopic surgical procedure, presence of a colorectal surgeon specialist at surgery, type of ostomy (colostomy, end ileostomy, loop ileostomy), preoperative ostomy siting, counseling, body mass index, American Society of Anesthesiologists classification, and radiation and/or chemotherapy status. Ostomies were evaluated by 4 WOC nurses as to stoma configuration, convexity use, patient self-sufficiency in stoma care, and complications. All 207 patients (53% women) who were eligible agreed to participate in the study. Patient median age was 70 years (range 19-94); 74% underwent elective surgery. Main diagnoses were colorectal cancer (62%) and inflammatory bowel disease (19%). Ostomy types were: colostomy (71%), end ileostomy (26%), and loop ileostomy (3%). One or more complications occurred in 35% of the patients (27% ostomy complications, 11% peristomal skin complications). A colostomy hernia was the most common surgical complication (20%), and significantly more women (69%) and emergency surgeries were noted among patients with a colostomy and an ostomy height of ≤5 mm. The use of convexity was significantly more common among patients with a stoma height of ≤5 mm than patients with stomas >5 mm (P ≤ 0.016) and among patients having emergency operations than among patients having elective surgery (P ≤ 0.045). Of the emergency surgeries, 37% had not been ostomy-sited (P <0.0001). With regular WOC nurse follow-up, the prevalence of peristomal skin complications in this population was low, and adequate ostomy height might have prevented the frequent use of convexity. Explorative studies are needed that consider differences in body configuration when determining optimal stoma height, especially for patients who require emergency surgery.

Tidskriftsartikel (refereegranskat)abstract
- In Sweden, pertussis was excluded from the national vaccination programme in 1979 until acellular vaccination was introduced in a highly endemic setting in 1996. The general incidence dropped 10-fold within a decade, less in infants. Infant pertussis reached 40–45 cases per 100,000 in 2008 to 2012; few of these cases were older than five months. We present an observational 15-year study on the severity of infant pertussis based on 1,443 laboratory-confirmed cases prospectively identified from 1998 to 2012 in the national mandatory reporting system and followed up by telephone contact. Analyses were made in relation to age at onset of symptoms and vaccination history. Pertussis decreased in non-vaccinated infants (2003 to 2012, p < 0.001), indicating herd immunity, both in those too young to be vaccinated and those older than three months. The hospitalisation rates also decreased (last five-year period vs the previous five-year periods, p <0.001), but 70% of all cases in under three month-old infants and 99% of cases with apnoea due to pertussis were admitted to hospital in 1998 to 2012. Median duration of hospitalisation was seven days for unvaccinated vs four days for vaccinated infants aged 3–5 months. Nine unvaccinated infants died during the study period.
