- Purpose: Previous studies have mostly focused on ophthalmological complications associated with being born extremely preterm despite that moderate-to-late preterm (MLP) account for 85% of all preterm births. The aim was to examine fundus morphology and visual function in adolescents born MLP, in comparison with controls born full-term.Methods: A prospective population-based cohort study of 247 MLP individuals (110 girls, gestational age 32-36 weeks) with no syndromes or history of retinopathy of prematurity participated in a neonatal study in 2002-2004. Later on, they have been included in ophthalmological follow-up studies at age 8 (n=50) and 12 (n=22). In the present study, 50 adolescents (26 girls; mean age 16.5 years) were examined regarding best corrected visual acuity (BCVA), refraction, and ocular morphology, measured by optical coherence tomography (Topcon, Japan). A group of 50 adolescents (30 girls, mean age 16.7 years) born full-term served as controls. Participants with refraction outside +/-6 diopters were excluded. T-test was used for statistical analysis.Results: The MLP-group (n=48) showed a thinner macular retinal nerve fibre layer (RNFL) inner mean in right eye (RE) (26.4±1.5 vs 27.1±1.7 μm; p=0.029) and in left eye (LE) (26.3±1.5 vs 27.0±1.5 μm; p=0.022) compared with controls. A thinner macular RNFL outer mean was found both in RE (40.2±4.4 vs 42.6±4.2 μm; p=0.011) and LE (40.3±4.0 vs 42.1±4.3 μm; p=0.034) (Fig.1A-B). A thicker central macular retinal thickness (MRT) (249.3±20.9 vs 239.9±16.4 μm; p=0.016) and a thinner total peripapillary (pp)RNFL (104.8±8.8 vs 109.1±8.3 μm; p=0.027) were found in RE. The BCVA in best eye was lower in the MLP-group (n=50) compared with controls (-0.09±0.08 vs -0.12±0.09 logMAR; p=0.022). At age 8, MLP births showed a thinner total macular volume and a thicker foveal minimum, central MRT, and central macular RNFL in RE. At age 12, a thicker foveal minimum and thinner outer macular RNFL were found in LE.Conclusions: MLP-birth may be associated with ophthalmological macular and ppRNFL changes as well as lower BCVA in adolescence. Similar morphology findings have been shown at younger ages, thus the fundus results persist into young adulthood.

- Background: Roux-en-Y gastric bypass (RYGB) among adolescents with obesity results in signif-icant weight loss; however, depot-specific changes have been understudied.Objective: We hypothesized that visceral adipose tissue (VAT) reduction in adolescents undergoing RYGB would be greater than other depots and associated with improvement in cardiometabolic risk factors.Setting: Three specialized treatment centers in Sweden. Methods: Fifty-nine adolescents underwent dual x-ray absorptiometry before surgery and at 1, 2, and 5 years after RYGB. Changes in body composition in multiple depots (total fat, lean body, gynoid fat, android fat, subcutaneous adipose tissue, and VAT) and cardiometabolic risk factors were assessed using multiple linear regression analysis and generalized estimating equations adjusting for age, sex, and baseline risk factor levels. Data are presented as percent change (95% CI) with regression models showing slopes and estimated P values.Results: At 1 year post-RYGB, a significant reduction was observed across all body composition measures (P , .001) with the greatest reduction observed in VAT (-65.1% [-68.7, -61.8]). From year 1 to 5 years post-RYGB, a regain was observed in all depots except lean body mass (1.2% [.3, 2.7], P 5 .105). A sex-specific difference in overall trajectories was only observed in lean body mass with males consistently having higher mean levels. Change in VAT at 1 year correlated with change in triglycerides (slope: .21 mg/dL/kg, P = .034) and fasting plasma insulin (slope: 44 pmol/L/kg, P = .027). Conclusions: Adiposity measures all decreased after RYGB but poorly predicted change in cardio-metabolic risk. Despite significant reductions at 1 year, a steady regain was observed out to 5 years, with values still well below baseline. Further research should consider control group comparison and extended follow-up.

- Aim: To assess the prevalence of neurodevelopmental problems in adolescents with severe obesity and their associations with binge eating and depression. Methods: Data were collected at inclusion in a randomised study of bariatric surgery in 48 adolescents (73% girls; mean age 15.7 ± 1.0 years; mean body mass index 42.6 ± 5.2 kg/m2). Parents completed questionnaires assessing their adolescents’ symptoms of attention-deficit/hyperactivity disorder and autism spectrum disorder and reported earlier diagnoses. Patients answered self-report questionnaires on binge eating and depressive symptoms. Results: The parents of 26/48 adolescents (54%) reported scores above cut-off for symptoms of the targeted disorders in their adolescents, but only 15% reported a diagnosis, 32% of adolescents reported binge eating, and 20% reported symptoms of clinical depression. No significant associations were found between neurodevelopmental problems and binge eating or depressive symptoms. Only a third of the adolescents reported no problems in either area. Conclusion: Two thirds of adolescents seeking surgical weight loss presented with substantial mental health problems (reported by themselves or their parents). This illustrates the importance of a multi-professional approach and the need to screen for and treat mental health disorders in adolescents with obesity.

Tidskriftsartikel (refereegranskat)abstract
- Background: Several studies have shown that younger women with polycystic ovary syndrome (PCOS) have decreased Health-Related Quality of Life (HRQoL) compared with women in general. Method: In this study peri- and postmenopausal women previously diagnosed with PCOS (n = 27) were compared with randomly selected, age-matched controls (n = 94). Mean age of the study participants was 52 years. Structured interviews and Short Form (SF)-36 questionnaires were used. Results: No differences in SF-36 scores were found, median for the physical summary score was 54 vs. 57, for women with PCOS and controls, respectively; and 53 vs. 53 for the mental summary score, with no differences in any of the eight dimensions of HRQoL. There were no significant difference in prevalence of depression and/or anxiety. The use of drugs for mood disorders was 22% in both groups. Conclusion: PCOS women of peri- and postmenopausal ages had similar HRQoL compared with age-matched controls.

- Objective: Despite the clear evidence of increased cardiovascular disease (CVD) risk factors, the long-term effect on CVD and mortality is still uncertain in women with PCOS, especially in the elderly. Studies in elderly women with PCOS are lacking. The objective was to study morbidity/mortality in PCOS women compared with a reference group up to a mean age above 80 years. Study design: A well-defined cohort of women with PCOS, examined in 1987 and 2008, was re-examined 32 years later in 2019 (age range 72–91 years), in parallel with an age-matched reference group. For deceased women register data was used, for women alive interviews were done, and medical records studied. Blood pressure and blood tests were analyzed. Morbidity and mortality data was available in 35/36 women with PCOS, and in 99/118 women in the reference group. Results: At mean age 81 years there was no difference in all-cause mortality (HR 1.1, ns), CVD-related mortality (HR 1.7, ns), all CVD (HR 1.2, ns), hypertension (HR 1.8, ns), type 2 diabetes (HR 1.7, ns), in levels of blood lipids, glucose, insulin or thyroid hormones. Comparing baseline data from the deceased and living women with PCOS, no differences were found regarding age, menopausal age, BMI, HOMA-IR, FAI, total testosterone or SHBG. However, deceased women with PCOS had a higher WHR (0.87 vs. 0.80; p-value < 0.01) at baseline. Conclusions: No evidence of increased all-cause mortality or CVD was found in women with PCOS. The elevated testosterone levels and CVD risk profile in PCOS present during perimenopause do not seem to be associated with increased CVD morbidity/mortality risk later in life. © 2022 The Authors

Tidskriftsartikel (refereegranskat)abstract
- Objective: Polycystic ovary syndrome (PCOS), affecting more than every 10th woman of reproductive age, is associated with increased risk factors for cardiovascular disease (CVD). Most knowledge regarding longtime consequences concerning morbidity is based on women where ovarian wedge resection (WR) was used as a surgical treatment, a method not used today. The aim of this study was to compare women with PCOS who had and had not undergone WR, regarding risk factors for CVD. The hypothesis was that women who had undergone WR had a more severe PCOS phenotype, and that this cohort thus had more associated CVD risk factors compared with women diagnosed through non-invasive methods.Study design: A cross-sectional study was performed. A PCOS cohort who underwent WR in the 1950-60 s (n = 27) were compared with a PCOS cohort diagnosed by NIH-criterions in the 1990s without WR (n = 32). Both cohorts were examined at perimenopausal age.Results: No differences were seen in prevalence of hypertension, obesity or type 2 diabetes mellitus (T2DM) between the women with PCOS with or without WR, respectively. The results were persistent irrespective of the lower mean BMI in the WR group, 26.4 vs. 30.7 kg/m2, p = 0.01. In the stratified group of overweight and obese, there was no difference in T2DM 27% vs 25% or hypertension 27% vs 25%, in WR and non-WR women with PCOS, respectively. The cohort diagnosed through WR had higher free androgen index (6.3 vs. 2.1, p < 0.01) and total testosterone (2.20 vs. 0.99 nmol/L, p < 0.01).Conclusion: No differences in CVD risk factors were found in perimenopausal women with PCOS with or without a previous WR, and irrespective of body weight. The results indicate that CVD morbidity and mortality from studies in women with PCOS who have undergone WR are generalizable to women with PCOS who have not undergone WR.

- There is a lack of knowledge about hormonal and anthropometric changes in women with polycystic ovary syndrome (PCOS) after the menopause.To study reproductive hormones and anthropometry in women with PCOS up to an age above 80 years.Prospective cohort study.University Hospital.A well-defined cohort of women with PCOS, previously examined in 1987 and 2008 (21 years period) was re-examined in 2019 (11 years period). Of the original cohort (n = 37), 22 women were still alive and 21 (age range 72-91 years) participated. Comparisons were made with age-matched controls (n = 55) from the original control cohort (BMI similar to PCOS women). The results were compared with results from 1987 and 2008.Hormonal measurements and physical examination.FSH, LH, testosterone, SHBG, free androgen index (FAI), hirsutism score, BMI, and waist-hip ratio (WHR).At mean age 81 years, FSH levels were lower in women with PCOS (50 vs. 70 IU/L) who were still more hirsute than controls (33% vs. 4%). No differences were found in FAI, testosterone, SHBG or LH levels, BMI or WHR.From perimenopausal age until the present age, levels of testosterone and FAI continued to decline in women with PCOS. SHBG levels continued to increase with age. FSH had not changed over time during the last eleven years.Women with PCOS at ages 72-91 had lower FSH levels, remained clinically hyperandrogenic and had similar FAI and body composition as controls.

- What are the predictive factors for later development of type 2 diabetes (T2DM) in women with polycystic ovary syndrome (PCOS)?Obesity and abdominal fat distribution in women with PCOS in the mid-fertile years were the major risk factors for T2DM development 24years later when lifestyle factors were similar to controls.Women with PCOS have an increased prevalence of T2DM.A longitudinal and cross-sectional study was performed. Women with PCOS were examined in 1992 and in 2016. Randomly selected, age-matched women from the general population served as controls.Women with PCOS (n=27), attending an outpatient clinical at a tertiary care centre for infertility or hirsutism were diagnosed in 1992 (mean age 30years) and re-examined in 2016 (mean age 52years). Women from the World Health Organization MONItoring of trends and determinants for CArdiovascular disease (WHO MONICA-GOT) 2008, aged 38-68years, served as controls (n=94), and they were previously examined in 1995. At both at baseline and at follow-up, women had blood samples taken, underwent a clinical examination and completed structured questionnaires, and the women with PCOS also underwent a glucose clamp test at baseline.None of women with PCOS had T2DM at baseline. At the 24-year follow-up, 19% of women with PCOS had T2DM versus 1% of controls (P<0.01). All women with PCOS who developed T2DM were obese and had waist-hip ratio (WHR) >0.85 at baseline. No difference was seen between women with PCOS and controls regarding use of high-fat diet, Mediterranean diet or amount of physical activity at follow-up at peri/postmenopausal age. However, women with PCOS had a lower usage of a high-sugar diet as compared to controls (P=0.01). The mean increases in BMI and WHR per year were similar in women with PCOS and controls during the follow-up period.The small sample size of women with PCOS and the fact that they were recruited due to infertility or hirsutism make generalization to women with milder forms of PCOS uncertain.Obesity and abdominal fat distribution, but not hyperandrogenism per se, in women with PCOS in the mid-fertile years were the major risk factors for T2DM development 24years later when peri/postmenopausal. Lifestyle factors were similar to controls at that time.The study was financed by grants from the Swedish state under the agreement between the Swedish government and the country councils, the ALF-agreement (ALFGBG-718611), the Gothenburg Medical Association GLS 694291 and 780821, the Swedish Heart Lung Foundation and Hjalmar Svensson Foundation. The authors have no conflict of interest.
