Bariatric surgery is most commonly carried out in women of childbearing age. Whilst fertility rates are improved, pregnancy following bariatric surgery poses several challenges. Whilst rates of many adverse maternal and foetal outcomes in obese women are reduced after bariatric surgery, pregnancy is best avoided for 12–24 months to reduce the potential risk of intrauterine growth retardation. Dumping syndromes are common after bariatric surgery and can present diagnostic and therapeutic challenges in pregnancy. Early dumping occurs due to osmotic fluid shifts resulting from rapid gastrointestinal food transit, whilst late dumping is characterized by a hyperinsulinemic response to rapid absorption of simple carbohydrates. Dietary measures are the mainstay of management of dumping syndromes but pharmacotherapy may sometimes become necessary. Acarbose is the least hazardous pharmacological option for the management of postprandial hypoglycemia in pregnancy. Nutrient deficiencies may vary depending on the type of surgery; it is important to optimize the nutritional status of women prior to and during pregnancy. Dietary management should include adequate protein and calorie intake and supplementation of vitamins and micronutrients. A high clinical index of suspicion is required for early diagnosis of surgical complications of prior weight loss procedures during pregnancy, including small bowel obstruction, internal hernias, gastric band erosion or migration and cholelithiasis.

ObjectiveInsulin-like growth factors are implicated in the development of diabetic nephropathy. IGF-binding protein 2 (IGFBP2) and IGF2 are expressed in the kidney, but their associations with diabetic nephropathy are unclear. We therefore tested the hypothesis that circulating levels of IGF2 and IGFBP2 predict longitudinal renal function in individuals with type 2 diabetes.Design and methodsIGFBP2 and IGF2 measurements were performed in 436 individuals (263 males) with type 2 diabetes. Linear mixed-effect regression analysis was used to model the relationship between plasma IGFBP2 concentration and longitudinal changes in estimated glomerular filtration rate (eGFR) over an 8-year period. Analyses were also performed for IGF1, IGF2, IGFBP1 and IGFBP3 concentrations as predictors of longitudinal renal outcomes.ResultsHigh IGFBP2 concentration at baseline was associated with a decreased eGFR over an 8-year period (β=−0.02, (95% confidence interval −0.03 to −0.01), P<0.001). High IGFBP1, IGFBP2 and IGFBP3 were also associated with low baseline eGFR concentration.ConclusionThis study demonstrates that IGFBP2 is a predictor of longitudinal deterioration of renal function in type 2 diabetes.

Bilateral paralysis of the facial nerve is a relatively rare presentation and often indicates a serious underlying medical condition. Guillain-Barré syndrome needs to be considered, among others in the differential diagnoses of such presentation. We present here the case of a 35 year old female who presented with bilateral facial nerve paralysis due to the Guillain-Barré syndrome.

What is already known about the subjectMaternal obesity is a risk factor for adverse maternal and foetal perinatal outcomes.The Institute of Medicine gives recommendations for weight gain during pregnancy based on initial body mass index (BMI) category, but the effects of these weight changes on pregnancy outcomes has not been adequately described. What this study adds: This study supports an association between gestational weight gain and adverse outcomes in obese pregnant women. Older and primiparous women in the cohort had the highest rates of weight gain, while socioeconomic deprivation did not influence weight changes. Women were recruited into the study at their antenatal booking visit and had weights measured throughout pregnancy. Patterns of weight gain were described and related to maternal and neonatal outcomes.Main outcome measure: The primary outcome was a composite measure consisting of any of twelve adverse maternal and fetal outcomes. This was compared by categorised pregnancy weight gain (<0 kg, 0-5 kg, 5.1-9 kg and >9 kg). patterns of weight gain varied widely and missing data was common and non-random.There was a significant association between increased weight gain during pregnancy and poor maternal and fetal outcome.Conclusions: Weight gain in obese women during pregnancy can be highly variable. Our study supports an association between increased weight gain in pregnancy and adverse perinatal outcomes.

Aintree LOSS is a community-based, multidisciplinary weight management programme for patients with severe and complex obesity, focusing on a flexible and individualized service with follow-up for up to 2 years. We evaluated all 2472 patients referred to the service between October 2009 and 2013. Demographic data were recorded at baseline, with the Index of Multiple Deprivation (IMD) used to measure socioeconomic deprivation. Weight was recorded at each visit. Mean body mass index at baseline was 45.6 (standard deviation 6.8), and 58.9% of patients lived in areas in the most deprived decile nationally. Of 2315 appropriate referrals, 1249 (55.1%) attended >2 visits; mean final weight loss was 3.50 ± 8.55 kg, and 24.1% achieved ≥5% weight loss. Of the patients, 754 (33.3%) attended for over 6 months; mean final weight loss was 4.94 ± 10 kg, and 34% achieved 5% weight loss. Multivariate logistic regression analysis showed increasing age, residence in a less deprived area and sleep apnoea to be independently associated with attendance for >6 months, and there was a linear relationship between 6-month attendance and deprivation quintile. Year-on-year analyses showed improvement in engagement over time, coinciding with efforts to improve access to the service. This work shows a multidisciplinary, community-based weight loss programme prioritizing a fully flexible and individualized approach functioning effectively in real-world practice. Maintaining engagement remains a challenge in weight loss programmes, and our results suggest younger patients living in areas with greater deprivation should be a target for efforts to improve engagement.

Introduction: Associations of insulin-like growth factor-II (IGF-II) and insulin-like growth factor binding protein-2 (IGFBP-2) with cardiovascular risk have been inadequately studied. We hypothesized that IGF-II and IGFBP-2 associate with longitudinal trends in lipid profiles in type 2 diabetes patients. Subjects and methods: Four hundred and eighty nine subjects with type 2 diabetes (age 27-87 years) from the Salford Diabetes Cohort were studied. Longitudinal clinical information was extracted for an eight-year period (2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) from an integrated electronic dataset of primary care and hospital data. Results: There were 294 male subjects and mean age was 62.9 years. At baseline, IGF-II concentration was 602 ng/mL. HDL cholesterol at baseline was associated with log-IGF-II concentration in a model adjusted for age, gender, baseline body-mass index (BMI), estimated glomerular filtration rate (eGFR) and lipid-lowering therapy. IGFBP-1 and IGFBP-2 were associated with high HDL-cholesterol. A higher circulating IGF-II concentration at baseline was also associated with longitudinal increase in HDL-cholesterol in mixed-effects regression analyses independent of IGF-I, IGFBP-1, IGFBP-2, IGFBP-3, age, gender, eGFR, BMI and lipid-lowering therapy. Log-transformed baseline concentrations of IGFBP-1 and IGFBP-2 were also associated with longitudinal elevation in HDL-cholesterol. No association was observed for IGF-II or IGFBP-2 with longitudinal LDL cholesterol trends. Conclusion: Our analyses based on 'real world' data demonstrate that higher baseline IGF-II and IGFBP-2 predict increased HDL concentration over time, implicating IGF-II in modulation of circulating HDL-cholesterol concentrations.

Increasing body mass index relates to increasing rates of dysglycaemia over time. Measures to encourage weight reduction should be key strategies to reduce dysglycaemia rates in severe mental illness. Prescribing statins may have been effective in improving the lipid profile in this group.
