Context Falling insulin requirements often lead to considerations of whether a pregnancy can continue safely or if delivery is indicated. Objective To evaluate prevalence and predictors of falling insulin requirements in pregnant women with preexisting diabetes delivering preterm and to explore the relationship to fetal asphyxia and neonatal morbidity. Methods A prospective cohort study of 101 consecutive singleton pregnant women with preexisting diabetes delivering preterm Results In total, 27% (27/101) experienced falling insulin requirements of median 30% (interquartile range 24-40) before delivery. In all women with type 1 diabetes, the prevalence was 37% (25/68), whereas it was 43% (24/56) in those with indicated preterm delivery and 6% (2/33) among women with type 2 diabetes. In women with type 1 diabetes and indicated preterm delivery, falling insulin requirements were first identified at 34 + 5 (33 + 6-35 + 4) weeks + days and delivery occurred 3 (1-9) days later. Gestational age at delivery, prevalence of suspected fetal asphyxia, and neonatal morbidity were similar in women with and without falling insulin requirements. Neither glycemic control, nausea, or preeclampsia was associated with falling insulin requirement. Conclusion Falling insulin requirements often preceded preterm delivery in women with type 1 diabetes, foremost when preterm delivery was indicated, but was not related to fetal asphyxia or neonatal morbidity. Whether falling insulin requirements in late pregnancy are a warning sign of placental insufficiency or mainly reflects variations in normal physiology needs further investigation.

In the 2019 WHO guidelines, the classification of gastro-entero-pancreatic neuroendocrine neoplasms (GEP NEN) has changed from one being based on Ki-67 proliferation index alone to one that also includes tumor differentiation. Consequently, GEP NENs are now classified as well-differentiated neuroendocrine tumor (NET), NET G1 (Ki-673%), NET G2 (Ki-67 3-20%) and NET G3 (Ki-6720%), and poorly differentiated neuroendocrine carcinoma (NEC) (Ki-6720%). It has been suggested that NET G3 should be treated as NET G2 with respect to surgery, while surgical management of NEC should be expanded from local disease to also include patients with advanced disease where curative surgery is possible. High grade mixed neuroendocrine-non-neuroendocrine neoplasms (MiNEN) have a neuroendocrine and a non-neuroendocrine component mostly with a poor prognosis. All studies evaluating the effect of surgery in NEC and MiNEN are observational and hold a risk of selection bias, which may overestimate the beneficial effect of surgery. Further, only a few studies on the effect of surgery in MiNEN exist. This review aims to summarize the data on the outcome of surgery in patients with GEP NET G3, GEP NEC and high grade MiNEN. The current evidence suggests that patients with NEN G3 and localized disease and NEN G3 patients with metastatic disease where curative surgery can be achieved may benefit from surgery. In patients with MiNEN, it is currently not possible to evaluate on the potential beneficial effect of surgery due to the low number of studies.

An increase in the Ki-67 index in neuroendocrine neoplasms over time in relation to prognosis has scarcely been investigated. We aimed to assess whether the Ki-67 index changed over time and also whether a change influenced prognosis. Second, we investigated the difference in the Ki-67 index between primary tumour and metastases. From 1 January 1995 to 31 December 2019, 108 consecutive patients with gastroenteropancreatic tumours were included. Patients were followed with regard to an increase in the Ki-67 index and all-cause mortality. Ki-67 determination of the primary tumour at diagnosis and at the time of radiological progression, including developed metastases, was performed. A significant increase in the Ki-67 index was defined as a doubling of the value at disease progression compared to the value at diagnosis. In addition, in 14 patients, the Ki-67 index of the primary tumour and present metastases at the time of diagnosis was investigated. At diagnosis, there were no differences in the Ki-67 index between primary tumours and metastases (P = .41). Sixty-five patients had a doubling of the Ki-67 index. The median Ki-67 index at the time of progression 17% (1%-90%) vs 5% (1%-60%) at the time of diagnosis (P = .006). A doubling of the Ki-67 index was independently associated with all-cause mortality (hazard ratio = 2.7 [1.3-6.3], P = 0.02), after adjustment for relevant co-variables including the Ki-67 index at baseline. Doubling of the Ki-67 index at the time of disease progression was associated with a significantly higher risk of all-cause mortality. We recommend that a Ki-67 index is obtained whenever disease progression is recorded by demonstrated progression because it may have impact on the choice of treatment.

An excessive consumption of licorice can cause pseudohyperaldosteronism, which can lead to severe hypokalaemia and hypertension. Glycyrrhizin in licorice root activates the renal mineralocorticoid receptor increasing sodium reabsorption and potassium excretion. In this case report, an otherwise healthy 43-year-old woman presented with severe hypokalaemia, rhabdomyolysis, electrocardiogram changes and focal paresis after having consumed 2-2,5 litres of licorice tea daily for approximately eight weeks.

Introduction Neuroendocrine neoplasms (NEN) of the appendix are often incidentally discovered after appendectomy. Appropriate management is debated. The purpose was to characterize a cohort of 335 appendix NEN and evaluate the risk of recurrence. Methods Retrospective collection of data from 335 patients referred to the Neuroendocrine Tumor Center at Rigshospitalet 2000–2019. Appendix goblet cell carcinoids and mixed neuroendocrine non-neuroendocrine neoplasms were excluded. Patients were followed until December 31st, 2019. No patients were lost to follow-up. Results Sixty-three percent of the patients were female. The median (range) age at diagnosis was 34 (9–92) years. Median follow-up was 66 (1–250) months. Median tumor size was 7 (1–45) mm with 10 (3%) tumors >20 mm. In 18 specimens (5%) resection margins were positive. Mesoappendiceal invasion was found in 113 (35%). Sixty-three (19%) patients underwent right-sided completion hemicolectomy (RHC) after appendectomy according to ENETS guidelines. Among these, 11 (17%) had lymph node metastases in the resected tissue. Further, one patient who underwent initial RHC due to colonic adenocarcinoma had lymph node metastases. All lymph node metastases were detected in patients with serotonin positive tumors. No patients with glucagon positive tumors (n = 85) had lymph node metastases. Mesoappendiceal invasion >3 mm and positive resection margins were associated with presence of lymph node metastases. No recurrences were recorded. Conclusion Following ENETS guidelines may lead to overtreatment of patients with respect to completion RHC. The risk of over- and undertreatment needs to be further evaluated.

Diabetes mellitus (DM) is associated with an adverse outcome in heart failure (HF). Increased concentrations of midregional proadrenomedullin (MR-proADM) have been associated with DM and are predictors of mortality in HF patients. The aim of this study was to elucidate the impact of DM on MR-proADM concentrations and the prognostic value regarding all-cause mortality and hospitalization among HF patients.We included 366 patients from an HF clinic; 69 (19%) had a history of DM and 40 (11%) had newly diagnosed DM (HbA1c ≥48 mmol/mol). The median MR-proADM concentration was unaffected by DM status (P = .20) but increased in HF patients with impaired renal function (P.001). During a median follow-up of 55 months, 189 died, and 292 either died or were hospitalized. After adjustment for clinically relevant parameters, MR-proADM was associated with all-cause mortality (hazard ratio [HR] 1.3, 95% confidence interval [CI] 1.1-1.4; P = .01) and the combined end point of death and hospitalization (HR 1.2, 95% CI 1.1-1.4; P = .02) per 1 SD increment of ln-transformed variable. No interaction between DM and MR-proADM was found regarding mortality or hospitalization.Diabetes status had no impact on MR-proADM concentrations or in the predictive ability of MR-proADM in HF patients.

SummaryBackground Chronic heart failure (HF) is characterized by reduced serum T3 levels and increased activity of the T3 degrading enzyme deiodinase D3. This may result in an intracellular composition of the cardiomyocyte mimicking that of hypothyroidism. Short-term T3-administration to systolic HF patients might be beneficial. Question Does long-term treatment with T3 have a beneficial effect on cardiac function and neurohormonal activation in chronic systolic HF patients with serum T3 levels below 1·6 nmol/l? Design A randomized, double-blind, cross-over, placebo-controlled intervention study with oral T3 treatment twice daily for 3 months. The T3 dose was uptitrated to a final dose avoiding reduced TSH levels. Primary end-point Left-ventricular ejection fraction (LVEF). Methods Cardiac imaging was performed using multiple gated tomographic radionuclide ventriculography (MUGA-SPECT). Neurohormonal stimulation was evaluated by plasma measurements of natriuretic peptides, aldosterone, renin, noradrenalin and copeptin levels. The patients were monitored for potential cardiac arrhythmias at the start of each treatment period. Results Thirteen patients completed the protocol. Mean LVEF was 43%, range: 37–52 and serum T3 levels 1·4 nmol/l (0·9–1·6). The T3 dose was 20 μg per day (10–40). TSH levels did not change between groups, whereas serum T3 levels increased in the active arm. Cardiac function as measured by LVEF, end-diastolic and end-systolic volumes and cardiac output did not change during T3-treatment and neither did the neurohormonal profile. There were no side-effects in terms of cardiac arrhythmias and no change in resting heart rate. Conclusions This study does not support the hypothesis that oral T3 treatment might be beneficial to patients with chronic, stable systolic HF with a modest degree of reduced LVEF and low-normal serum T3 concentrations. The study included both functional studies of heart contractility as well as measures of the neurohormonal activation.

Background: Heart failure (HF) patients with diabetes (DM) have an adverse prognosis and reduced functional capacity, which could be associated with cardiac fibrosis, increased chamber stiffness and reduced left ventricular (LV) contractile reserve. Galectin-3 (Gal-3) and fibulin-1 are circulating biomarkers potentially reflecting cardiac fibrosis. We hypothesize that plasma levels of Gal-3 and fibulin-1 are elevated in HF patients with DM and are associated with reduced LV contractile reserve in these patients. Methods: A total of 155 patients with HF with reduced ejection fraction underwent a low-dose dobutamine echocardiography and blood sampling for biomarker measurements. Patients were classified according to history of DM and an oral glucose tolerance test (OGTT) as: normal glucose tolerance (NGT) (n = 70), impaired glucose tolerance (IGT) (n = 25) and DM (n = 60). Results: Galectin-3 levels were elevated in DM patients as compared to non-diabetic patients (P = 0.02), while higher fibulin-1 levels were observed in HF patients with IGF and DM (P = 0.07). Reduced LV contractile reserve was associated with increasing Gal-3 levels (β = -0.19, P = 0.03) although, this association was attenuated after adjustment for estimated glomerular filtration rate (P = 0.66). Fibulin-1 was not associated with LV contractile reserve (P = 0.71). Conclusions: Galectin-3 and fibulin-1 levels were elevated in HF patients with impaired glucose metabolism. However, reduced LV contractile reserve among HF patients with DM does not to have an independent impact on plasma Gal-3 and fibulin-1 levels.

Chronic stress is prevalent in patients with ischemic heart disease (IHD) and worsens the long-term prognosis. Chronic stress is vaguely defined, but is associated with depressive symptoms, reduced psychological wellbeing, and reduced quality of life (QOL). Stress seems to induce hyperalgesia.The aim of the present study was to evaluate hyperalgesia by pressure pain sensitivity (PPS) in patients with IHD, and compare PPS to questionnaires measuring depressive symptoms, reduced psychological wellbeing, and QOL as markers of stress. Design. A cross-sectional study of 361 subjects with IHD.PPS was measured on the sternum, and compared to the questionnaires: Clinical stress symptoms score (CSS), Major Depression Inventory (MDI), WHO-5 Wellbeing Index, and SF-36 QOL score.PPS correlated to CSS (r = 0.20, p0.001), MDI (r = 0.14, p = 0.02), SF-36 mental component summary score (MCS) (r = - 0.10, p = 0.049), SF-36 physical component summary score (PCS) (r = - 0.17, p = 0.001), and self-perceived stress level (r = 0.15, p = 0.006). CSS correlated similarly (r = 0.5-0.7, all p0.001). Comparing subjects within the lowest vs. highest tertiles of PPS and CSS, the mean MDI score was 4 vs. 15, WHO-5 was 77 vs. 53, SF-36 PCS was 53 vs. 43, and SF-36 MCS was 58 vs. 46; all p0.001.PPS reflected to a modest degree markers of chronic stress in IHD. PPS and CSS together might be useful as easy-to use tools for evaluating these markers in IHD patients.

The aim of this study was to test i) whether patients having diabetes and ischemic heart disease (IHD), i.e., patients suffering from two chronic diseases, demonstrate a higher degree of chronic stress when compared with patients suffering from IHD alone, and ii) whether suffering from the two chronic diseases results in an elevation in specific elements of the chronic stress concept. A total of 361 participants with IHD were included, of whom 47 suffered from concomitant diabetes. Stress was measured by pressure pain sensitivity (PPS) and by the following questionnaires: the Major Depression Inventory (MDI), the SF-36 Quality of Life questionnaire (SF-36 QOL), the WHO-5 Well-being Index, and the clinical stress signs (CSSs) scale. Participants with diabetes and IHD had a higher MDI score, a lower SF-36 physical component summary score, and a lower score of several sub-measurements of the SF-36 mental component score when compared with patients with IHD without diabetes. No significant differences were observed regarding stress measured by the PPS measure, the WHO-5 Well-being Index, or the number of CSSs. In conclusion, the combination of diabetes and IHD seems to be associated with increased depressive symptoms, lower overall physical QOL, and reduced mental QOL on several sub-elements of the questionnaire. This should be recognized in the management of patients with double diagnoses.

Udgivelsesdato: 2008 OBJECTIVE: Oxygen-dependent changes in vascular diameters may be detrimental when the endothelium is dysfunctional. DESIGN: Endothelial responsiveness was evaluated by brachial ultrasound and flow-mediated/nitroglycerin-mediated dilation (FMD/NMD). FMD/NMD was investigated in males with increased risk of cardiovascular disease (mean age 44+/-2 years, n=10) and matched controls without risk factors (44+/-2 years, n=10). FMD/NMD was assessed during normoxia (21% O2, 79% N2), while inhaling hypoxic gas (12.5% O2, FMDHyp/NMD), and 100% O2 supplementation (FMDO2/NMD). In a second study we addressed the effect of lipid lowering. Twenty persons with cardiovascular risk (mean age 50+/-2 years) were treated with atorvastatin (80 mg/day) and FMD/NMD was measured during normoxia, hypoxia and oxygen supplementation before, after 1 day and 3 months. RESULTS: Oxygen supplementation evoked vasoconstriction, while FMDHyp/NMD was reduced compared to FMD/NMD. Atorvastatin significantly lowered total cholesterol, LDL cholesterol, and ADMA after 1 day of treatment, while triglycerides, ApoB and hsCRP were lowered after 3 months. Atorvastatin did not change FMD/NMD irrespective of oxygen tension. CONCLUSION: Irrespective of risk factors or atorvastatin, hypoxia reduced endothelial vasodilation while oxygen supplementation evoked vasoconstriction.
