Post-bariatric hypoglycaemia (PBH) is typically a post-prandial hypoglycaemia occurring about 2–4 h after eating in individuals who have undergone bariatric surgery. PBH develops relatively late after surgery and often after discharge from post-surgical follow-up by bariatric teams, leading to variability in diagnosis and management in non-specialist centres. Aim: The overall aim was to improve and standardise clinical practice in the diagnosis and management of PBH. The objectives were: (1) to undertake an up-to-date review of the current literature; (2) to formulate practical and evidence-based guidance regarding the diagnosis and treatment of PBH; (3) to recommend future avenues for research in this condition. Method: A scoping review was undertaken after an extensive literature search. A consensus on the guidance and confidence in the recommendations was reached by the steering group authors prior to review by key stakeholders. Outcome: We make pragmatic recommendations for the practical diagnosis and management of PBH, including criteria for diagnosis and recognition, as well as recommendations for research areas that should be explored. Plain English summary: Post-bariatric hypoglycaemia (PBH) is a condition that commonly affects people who have undergone weight loss surgery. In this condition, people develop low blood sugar occurring about 2–4 h after meals, leading to debilitating symptoms such as hunger, sweating, anxiety, palpitations and even blackouts and fainting. PBH is becoming more common as weight loss surgery is being taken up by more people to help with their weight and to help with diabetes. The condition often develops after the patient has been discharged from follow-up after their surgery, which can lead to inconsistent diagnosis and treatment in non-specialist healthcare centres. The lack of clear information and evidence in the existing scientific literature further contributes to the variation in care. To address this problem, the Society for Endocrinology has created new guidelines to help healthcare professionals accurately diagnose and manage this condition. The guidelines were developed with input from dietitians, surgeons and doctors specialising in weight loss, and hormone specialists.

Objectives Identifying the prevalence of palliative care (PC) needs among patients who die at the emergency department (ED) and to assess symptom control and aggressiveness of care. Methods We conducted a decedent cohort study of adults deceased at the ED of a Portuguese teaching hospital in 2016. PC needs were identified using the National Hospice Organization terminality criteria and comorbidities measurement by the Charlson’s Index. Results 384 adults died at the ED (median age 82 (IQR 72–89) years) and 78.4% (95% CI 73.9% to 82.2%) presented PC needs. Only 3.0% (n=9) were referred to the hospital PC team. 64.5%, 38.9% and 57.5% experienced dyspnoea, pain and confusion, respectively. Dyspnoea was commonly medicated (92%), against 56% for pain and 8% for confusion. Only 6.3% of the patients were spared from aggressive interventions, namely blood collection (86.0%) or intravenous fluid therapy (63.5%). The burden of aggressive interventions was similar between those with or without withhold cardiopulmonary resuscitation order (median 3 (2–4) vs 3 (2–5)), p=0.082. Conclusions Nearly four out of five adults who died at the ED had PC needs at the time of admission. Most experienced poor symptom control and care aggressiveness in their last hours of life and were mostly unknown to the PC team. The findings urge improvements in the care provided to patients with PC needs at the ED, focusing on patient well-being and increased PC referral.

Despite the fact that there can be argued that no single cell in the human body can be devoid of molecular tools that fit into the broad definition of an endocrine function, some organs are primarily dedicated to hormone secretion and are therefore designated endocrine glands. Under regulation by pituitary gland (reviewed on the previous chapter), three peripheral organs are exclusively devoted to endocrine functions: the thyroid, the parathyroid and the adrenal glands. This Chapter on endocrine system will cover the signaling pathways implied in these three organs, with identification of their particular and shared features.

Iodine deficiency remains a worldwide problem with two billion individuals having insufficient iodine intake. Universal salt iodisation was declared by UNICEF and WHO as a safe, cost-effective, and sustainable way to tackle iodine deficiency. In Portugal, the few studies available unravel an iodine status below the WHO guidelines for pregnant women and school-aged children. In the present study, the iodine levels of household salt consumed in Portugal was assessed, for the first time. Non-iodised (median 14 ppm) and fortified (median 48 ppm) marine salt samples showed iodine levels lower than the minimum and above the maximum threshold recommended by non-mandatory Portuguese law and WHO recommendations, respectively. This study calls attention to the fact that marine salt per se, in spite of containing a natural high amount of iodine, requires further fortification in order to be used as an effective tool to deal with iodine insufficiency.
