Combined robotic surgery for concomitant treatment of endometrial cancer and obesity.

BACKGROUND: Endometrial Cancer (EC) is strongly linked to obesity. Bariatric surgery is recognized as a long-term solution for weight loss in severely obese patients. This pilot study investigates the feasibility, intraoperative and 30-day morbidity outcomes of integrating gynecological surgical staging and bariatric robotic surgery in class II and III obese patients affected by early EC or Endometrial Intraepithelial Neoplasia (EIN). METHODS: Patients aged over 18 years old with early EC or EIN and class II and III obesity (Body mass index (BMI) ≥ 35 kg/m2) who are surgical and anesthesiologic candidates. Standard robotic surgery for early EC staging performed alone (THBSO group) or in conjunction with sleeve gastrectomy (THBSO + SG group) for obesity management was proposed. RESULTS: Of the 13 patients who met the inclusion criteria, 5 (38.46%) opted for combined surgery. The groups showed a significant difference in preoperative BMI (49.68 kg/m2 vs. 40.24 kg/m2 p = 0.017 with and without SG), preoperative weight (143.92 kg vs. 105.62 kg p = 0.004 with and without SG), preoperative (p = 0.01) and postoperative (p = 0.005) aspartate transaminase (AST). The THBSO + SG group had higher anesthesia induction end-tidal carbon dioxide (ETCO2) (p = 0.05), final Partial pressure of carbon dioxide (PaCO2) (p = 0.044), anesthesia induction lactate (p = 0.001) and final lactate (p = 0.011) without a significant difference in final pH (p = 0.31). Operative time was longer in the THBSO + SG group (p < 0.001), but this did not result in longer ICU (p = 0.351), total hospital stays (p = 0.208), nor increased blood loss and transfusion. The simultaneous combined approach had an 80% success rate. At 6 months, the THBSO + SG group achieved significantly greater weight loss than the THBSO group (ΔBMI - 11.81 kg/m2 vs - 1.72 kg/m2, p = 0.003, with and without SG). CONCLUSION: Integrating robotic EC staging with SG in obese women with early EC increased the operative time without increasing intraoperative risks, early and 30 days post-surgery complication and offering a promising approach to simultaneously treating both conditions.

miRNA levels are associated with body mass index in endometrial cancer and may have implications for therapy.

Endometrial cancer (EC) is the most prevalent gynecological cancer in high-income countries. Its incidence is skyrocketing due to the increase in risk factors such as obesity, which represents a true pandemic. This study aimed to evaluate microRNA (miRNA) expression in obesity-related EC to identify potential associations between this specific cancer type and obesity. miRNA levels were analyzed in 84 EC patients stratified based on body mass index (BMI; ≥30 or <30) and nine noncancer women with obesity. The data were further tested in The Cancer Genome Atlas (TCGA) cohort, including 384 EC patients, 235 with BMI ≥30 and 149 with BMI <30. Prediction of miRNA targets and analysis of their expression were also performed to identify the potential epigenetic networks involved in obesity modulation. In the EC cohort, BMI ≥30 was significantly associated with 11 deregulated miRNAs. The topmost deregulated miRNAs were first analyzed in 84 EC samples by single miRNA assay and then tested in the TCGA dataset. This independent validation provided further confirmation about the significant difference of three miRNAs (miR-199a-5p, miR-449a, miR-449b-5p) in normal-weight EC patients versus EC patients with obesity, resulting significantly higher expressed in the latter. Moreover, the three miRNAs were significantly correlated with grade, histological type, and overall survival. Analysis of their target genes revealed that these miRNAs may regulate obesity-related pathways. In conclusion, we identified specific miRNAs associated with BMI that are potentially involved in modulating obesity-related pathways and that may provide novel implications for the clinical management of obese EC patients.

Semaglutide for Treating Obesity Induced by Craniopharyngioma Resection: A Successful Case Study.

Surgical treatment of craniopharyngioma often leads to a rapid and dramatic weight gain, leading to hypothalamic obesity. Treatment focused on the diet, physical activity, and different types of drugs have very often provided unsatisfactory results. To date, no data have been reported on hypothalamic obesity (HO) regarding the use of semaglutide, a novel type 1 receptor glucagon-like peptide-1 agonist, to limit body weight gain after surgical removal of a neoplasm, despite its already documented efficacy in obesity treatment. In this case report, we tested semaglutide in an 18-year-old patient with HO induced by a surgical intervention for craniopharyngioma. A very favorable treatment response was found in terms of body weight reduction and improvement in metabolic parameters. Our patient lost more than than 30 kg after only 6 months of therapy, which has never been reported before in the literature on HO.

Prevalence and Incidence of Atrial Fibrillation in a Large Cohort of Adrenal Incidentalomas: A Long-Term Study.

CONTEXT: Chronic glucocorticoids excess leads to morphological and functional cardiac alterations, a substrate for arrhythmias. Autonomous cortisol secretion (ACS) in adrenal incidentalomas is a model of chronic endogenous hypercortisolism. OBJECTIVE: To investigate prevalence and incidence of atrial fibrillation (AF) in a large cohort of patients with ACS. DESIGN: Retrospective study. SETTING: University hospital. PATIENTS: Patients evaluated between 1990 and 2018 for adrenal incidentalomas (n = 632), without pheochromocytoma, primary aldosteronism, Cushing syndrome, congenital adrenal hyperplasia, and adrenal malignancy. Cortisol after 1-mg dexamethasone suppression test < or > 50 nmol/L defined nonsecreting tumors (NST) (n = 420) and ACS (n = 212), respectively. INTERVENTION: Assessment of AF at baseline (n = 632) and during a median follow-up of 7.7 years retrospectively (NST, n = 249; ACS, n = 108). Comparison with general population. MAIN OUTCOME MEASURE: Prevalence and incidence of AF. RESULTS: AF prevalence was higher in patients with ACS (8.5%) than NST (3.1%, P = 0.003) and the general population (1.7%; P < 0.001 vs ACS, P = 0.034 vs NST). The age-adjusted rate ratio to the general population was 1.0 for NST and 2.6 for ACS. AF was associated with ACS (odds ratio, 2.40; 95% confidence interval [CI], 1.07-5.39; P = 0.035). The proportion of patients with AF at last evaluation was higher in ACS (20.0%) than NST (11.9%; P = 0.026). ACS showed a higher risk of incident AF than NST (hazard ratio, 2.95; 95% CI, 1.27-6.86; P = 0.012), which was associated with post-dexamethasone cortisol (hazard ratio, 1.15; 95% CI, 1.07-1.24; P < 0.001), independently of known contributing factors. CONCLUSIONS: Patients with adrenal incidentalomas and ACS are at risk of AF. Electrocardiogram monitoring may be recommended during follow-up.

Lessons learnt from TB screening in closed immigration centres in Italy.

BACKGROUND: Between June 2012 and December 2013 Médecins Sans Frontières launched a pilot project with the aim of testing a strategy for improving timely diagnosis of active pulmonary TB among migrants hosted in four centres of identification and expulsion (CIE) in Italy. METHODS: This is a descriptive study. For active TB case finding we used an active symptom screening approach among migrants at admission in four CIE's. Here we describe the feasibility and the yield of this programme. RESULTS: Overall, 3588 migrants were screened, among whom 87 (2.4%) had a positive questionnaire. Out of 30 migrants referred for further investigations, three were diagnosed as having TB, or 0.1% out of 3588 individuals that underwent screening. Twenty-five (29%, 25/87) migrants with positive questionnaires were not referred for further investigation, following the doctors' decision; however, for 32 (37%, 32/87) migrants the diagnostic work-out was not completed. In multivariate analyses, being over 35 years (OR 1.7; 95% CI 1.1-2.6) and being transgender (OR 4.9; 95% CI 2.1-11.7), was associated with a positive questionnaire. CONCLUSIONS: TB screening with symptom screening questionnaires of migrants at admission in closed centres is feasible. However, to improve the yield, follow-up of patients with symptoms or signs suggestive for TB needs to be improved.

Neglect of a Neglected Disease in Italy: The Challenge of Access-to-Care for Chagas Disease in Bergamo Area.

OBJECTIVES: Chagas disease (CD) represents a growing problem in Europe; Italy is one of the most affected countries but there is no national framework for CD and access-to-care is challenging. In 2012 Médecins Sans Frontières (MSF) started an intervention in Bergamo province, where many people of Latin American origin (PLAO) are resident. A new model-of-care for CD, initiated by Centre for Tropical Diseases of Sacro Cuore Hospital, Negrar (CTD), the NGO OIKOS and the Bolivian community since 2009 in the same area, was endorsed. Hereby, we aim to describe the prevalence of CD and the treatment management outcomes among PLAO screened from 1st June 2012 to 30th June 2013. METHODS: Retrospective cohort study using routine program data. Screening sessions were done in Bergamo at OIKOS outpatient service and serological confirmation, staging and treatment for CD was offered at the CTD. MSF provided health education on CD, awareness generation prior to screening days, pre-test and post-test counselling through cultural mediators of Latin American origin. RESULTS: Of 1305 PLAO screened, 223(17%) had CD. Among 210 patients eligible for treatment, 102(49%) were lost-to-follow-up before treatment. The median delay from diagnosis to treatment was 4 months (range 0.7-16.6 months). Among 108 started on treatment, 63(58%) completed treatment, 36(33%) interrupted treatment, (33 for drug side-effects, two for patients decision and one due to pregnancy), 6(6%) were lost-to-follow-up and 3(3%) were on treatment at study censuring. CONCLUSION: In this first study focusing on process of care for CD in Italy, less than 30% of patients completed treatment with drop-outs along the cascade of care. There is an urgent need to involve affected communities and local regional health authorities to take part to this model-of-care, adapting it to the local epidemiology. The Italian health authorities should take steps in advocating for a change in the current paradigm.

Steroid Profiling by LC-MS/MS in Nonsecreting and Subclinical Cortisol-Secreting Adrenocortical Adenomas.

CONTEXT: Long-term follow-up studies revealed that patients with subclinical hypercortisolism (SH) due to adrenocortical adenomas have an increased incidence of cardiovascular diseases and mortality. No studies have yet investigated the steroid profile and its implications in patients with SH. OBJECTIVE: The objective of the study was to analyze the steroid profile by liquid chromatography-tandem mass spectrometry in sera from patients with unilateral adrenocortical adenomas. DESIGN: This was a cross-sectional study. SETTING: The study was conducted at an outpatient clinic. PARTICIPANTS: Patients with adrenocortical adenomas (nonsecreting, n = 66; SH, n = 28) and 188 age- and sex-matched controls drawn from the general population participated in the study. MAIN OUTCOME MEASURES: Cortisol, 21-deoxycortisol, 11-deoxycortisol, 17-hydroxyprogesterone, androstenedione, dehydroepiandrosterone, T, progesterone, 11-deoxycorticosterone, and corticosterone in the basal condition and after a 1-24 ACTH test, and clinical data were measured. RESULTS: Patients with SH showed lower basal and 1-24 ACTH-stimulated levels of dehydroepiandrosterone and androstenedione than those with nonsecreting adenomas and controls. T was also lower in SH females. Receiver-operating characteristic curves showed that androgens had good accuracy in predicting SH (sensitivity and specificity were 71% and 76% for dehydroepiandrosterone and 69% and 61% for androstenedione, respectively). Increased cortisol and reduced dehydroepiandrosterone levels were independently associated with increased waist circumference. Cortisol was also independently associated with increased number of cardiovascular risk factors in SH patients. After 1-24 ACTH stimulation, the SH patients also showed increased production of 21-deoxycortisol and 11-deoxycorticosterone. CONCLUSIONS: Liquid chromatography-tandem mass spectrometry steroid profile performed for the first time in sera from patients with adrenocortical adenomas showed impaired secretion of several steroids in SH patients. This fingerprint can help in better characterizing the functional status of these tumors.

Obesity-related proliferative diseases: the interaction between adipose tissue and estrogens in post-menopausal women.

Epidemiological studies have shown that overweight and cancer are closely related, even though obesity alone does not apparently heighten cancer risk by the same amount. Given the low overall risk of all cancers with obesity, it is unlikely that obesity alone causes cancer, but should instead be considered as a tumor promoter. There are three main hypotheses that could explain how obesity might contribute to cancer development and growth: the inflammatory cytokines from adipose tissue hypothesis, the insulin resistance and hyperinsulinemia hypothesis, and the unopposed estrogen cancer hypothesis. The link between obesity and cancer is that adipocytes constitute a major component of the tumor microenvironment for breast and abdominally metastasizing cancers, promoting tumor growth. This review will mainly focus attention on the relationship between adipose tissue, estrogens, and cancer risk.

Cardiovascular events and mortality in patients with adrenal incidentalomas that are either non-secreting or associated with intermediate phenotype or subclinical Cushing's syndrome: a 15-year retrospective study.

BACKGROUND: Incidental discovery of adrenal masses has increased over the past few years. Mild alterations in cortisol secretion without clinical signs of overt hypercortisolism (subclinical Cushing's syndrome) are a common finding in patients with these tumours. Although metabolic alterations and increased cardiovascular risk have been noted in patients with subclinical Cushing's syndrome, incidence of cardiovascular events and mortality in the long term have not been assessed. We aimed to ascertain the frequency of new cardiovascular events and mortality in patients with non-secreting adrenal incidentalomas, tumours of intermediate phenotype, or those causing subclinical Cushing's syndrome. METHODS: From January, 1995, to September, 2010, consecutive outpatients with adrenal incidentalomas who were referred to the endocrinology unit of S Orsola-Malpighi Hospital, Bologna, Italy, were enrolled into our study. Individuals were assessed every 18-30 months for the first 5 years (mean follow-up 7·5 [SD 3·2] years, range 26 months to 15 years). Cortisol concentrations after the 1 mg dexamethasone suppression test (DST) were used to define non-secreting (+50 nmol/L) and intermediate phenotype (50-138 nmol/L) adrenal incidentalomas and subclinical Cushing's syndrome (+138 nmol/L). At the end of follow-up, patients were reclassified as having either unchanged or worsened secreting patterns from baseline. FINDINGS: 198 outpatients were assessed; at the end of follow-up, 114 patients had stable non-secreting adrenal incidentalomas, 61 had either a stable intermediate phenotype or subclinical Cushing's syndrome, and 23 had a pattern of secretion that had worsened. By comparison with patients with stable non-secreting adrenal incidentalomas, the incidence of cardiovascular events was higher in individuals with a stable intermediate phenotype or subclinical Cushing's syndrome (6·7% vs 16·7%; p=0·04) and in those with worsened secreting patterns (6·7% vs 28·4%; p=0·02). Cardiovascular events were associated independently with a change (from baseline to the end of follow-up) in cortisol concentrations post DST (hazard ratio 1·13, 95% CI 1·05-1·21; p=0·001). Survival rates for all-cause mortality were lower in patients with either stable intermediate phenotype adrenal incidentalomas or subclinical Cushing's syndrome compared with those with stable non-secreting masses (57·0% vs 91·2%; p=0·005). Factors associated with mortality were age (hazard ratio 1·06, 95% CI 1·01-1·12; p=0·03) and mean concentrations of cortisol post DST (1·10, 1·01-1·19; p=0·04). Compared with patients with stable non-secreting adrenal incidentalomas, unadjusted survival for cardiovascular-specific mortality was lower in patients with either a stable intermediate phenotype or subclinical Cushing's syndrome (97·5% vs 78·4%; p=0·02) and in those with worsened secreting patterns (97·5% vs 60·0%; p=0·01). Cancer mortality did not differ between groups. INTERPRETATION: Even when clinical signs of overt hypercortisolism are not present, patients with adrenal incidentalomas and mild hypercortisolism have an increased risk of cardiovascular events and mortality. FUNDING: None.

Addison's disease: a survey on 633 patients in Padova.

OBJECTIVE: Addison's disease (AD) is a rare endocrine condition. DESIGN: We aimed to evaluate clinical, immunologic, adrenal imaging, and genetic features in 633 Italian patients with AD followed up since 1967. METHODS: Adrenal cortex autoantibodies, presence of other autoimmune and nonautoimmune diseases, nonadrenal autoantibodies, adrenal imaging, and genetic profile for HLA-DRB1 and AIRE were analyzed. RESULTS: A total of 492 (77.7%) patients were found to be affected by autoimmune AD (A-AD), 57 (9%) tuberculous AD, 29 (4.6%) genetic-associated AD, 10 (1.6%) adrenal cancer, six (0.94%) post-surgical AD, four (0.6%) vascular disorder-related AD, three (0.5%) post-infectious AD, and 32 (5.1%) were defined as idiopathic. Adrenal cortex antibodies were detected in the vast majority (88100%) of patients with recent onset A-AD, but in none of those with nonautoimmune AD. Adrenal imaging revealed normal/atrophic glands in all A-AD patients: 88% of patients with A-AD had other clinical or subclinical autoimmune diseases or were positive for nonadrenal autoantibodies. Based on the coexistence of other autoimmune disorders, 65.6% of patients with A-AD were found to have type 2 autoimmune polyendocrine syndrome (APS2), 14.4% have APS1, and 8.5% have APS4. Class II HLA alleles DRB1*03 and DRB1*04 were increased, and DRB1*01, DRB1*07, DRB1*013 were reduced in APS2 patients when compared with controls. Of the patients with APS1, 96% were revealed to have AIRE gene mutations. CONCLUSIONS: A-AD is the most prevalent form of adrenal insufficiency in Italy, and ∼90% of the patients are adrenal autoantibody-positive at the onset. Assessment of patients with A-AD for the presence of other autoimmune diseases should be helpful in monitoring and diagnosing APS types 1, 2, or 4 and improving patients' care.

High prevalence of chronic thyroiditis in patients with polycystic ovary syndrome.

OBJECTIVE: A higher prevalence (26.9% versus 8.3% of controls) of autoimmune thyroiditis (AIT) in polycystic ovary syndrome (PCOS) has been reported in one study to date. We aimed to evaluate the prevalence of clinical, subclinical, potential thyroid autoimmune diseases and other organ-specific autoimmunity in a group of Italian patients with PCOS. STUDY DESIGN: 113 consecutive patients referred to our endocrinology unit as outpatients over 18 months, and diagnosed with PCOS according to the Rotterdam criteria, were included in the study, and 100 age-matched healthy women were enrolled as controls. Each patient was evaluated for family and personal history of autoimmune and non-autoimmune diseases and tested for autoantibodies against thyroperoxidase, thyroglobulin, parietal cells, intrinsic factor, adrenal-cortex, 21-hydroxylase, steroid-producing cells, 17-alpha-hydroxylase, side-chain cleavage enzyme, islet-cells, glutamic-acid decarboxylase, nuclei and mitochondria. All patients had serum TSH, FT4 and FT3 tested and patients with thyroid autoantibodies and/or abnormal TSH levels had an ultrasound thyroid scan. An oral glucose tolerance test and measurements of serum anti-Mullerian hormone (AMH) and inhibin B levels were carried out. RESULTS: AIT was present in 30/113 (27%) patients compared with 8% of controls (p<0.001). Subclinical hypothyroidism was detected in 13/30 (43%) patients with AIT; the remaining patients had normal thyroid function. The prevalence of non-thyroid autoantibodies in PCOS patients was not different from controls. AMH concentration was higher in PCOS patients compared to controls, but there was no difference between AIT and non-AIT groups. CONCLUSIONS: The prevalence of AIT in patients with PCOS was significantly higher than in controls. No other autoimmune diseases were associated with PCOS. This observation suggests that PCOS patients should be screened for AIT.
