Oxytocin levels in response to CRH administration in hypopituitarism and hypothalamic damage: a randomized, crossover, placebo-controlled trial.

Increasing evidence supports the presence of oxytocin deficiency (OXT-D) in patients with hypopituitarism and hypothalamic damage (HHD), that might be associated with neuropsychological deficits and sexual dysfunction, leading to worse quality of life (QoL). Therefore, identifying a provocative test to diagnose an OXT-D will be important. Corticotropin-releasing hormone (CRH) is a candidate for such a test as it increases oxytocin secretion in animal models.

Biomarkers of Frailty in Patients with Advanced Chronic Liver Disease Undergoing a Multifactorial Intervention Consisting of Home Exercise, Branched-Chain Amino Acids, and Probiotics.

Frailty in cirrhosis or advanced chronic liver disease (ACLD) is a relevant prognostic factor. In the present study, we aimed to analyze potential biomarkers associated with frailty and its improvement in patients with ACLD. We analyzed the serum of outpatients with ACLD who participated in a previous study (Román, Hepatol Commun 2024) in which frailty was assessed using the liver frailty index (LFI), and patients who were frail or prefrail were randomized to a multifactorial intervention (home exercise, branched-chain amino acids, and probiotics) or control for 12 months.

Home exercise, branched-chain amino acids, and probiotics improve frailty in cirrhosis: A randomized clinical trial.

Background: Frailty is a predictive factor of hospitalization, falls, and mortality in patients with cirrhosis, regardless of the degree of liver failure. The aim was to analyze whether a multifactorial intervention consisting of home-based exercise, branched-chain amino acids, and a multistrain probiotic can improve frailty in these patients.

Methods: Outpatients with cirrhosis were classified according to the Liver Frailty Index (LFI).

Clinical and outcome comparison of genetically positive vs. negative patients in a large cohort of suspected familial hypocalciuric hypercalcemia.

Objective: Biochemical suspicion of familial hypocalciuric hypercalcemia (FHH) might provide with a negative (FHH-negative) or positive (FHH-positive) genetic result. Understanding the differences between both groups may refine the identification of those with a positive genetic evaluation, aid management decisions and prospective surveillance. We aimed to compare FHH-positive and FHH-negative patients, and to identify predictive variables for FHH-positive cases.

Association between inadequate weight gain according to the institute of medicine 2009 guidelines and pregnancy outcomes in women with thyroid disorders.

Purpose: Gestational weight gain (GWG) is an important contributor to pregnancy outcomes in the general obstetric population and different subgroups. The corresponding information in women with thyroid conditions is limited. We aimed to evaluate the relationship between GWG according to institute of medicine (IOM) and pregnancy outcomes in women with thyroid disorders.

(2) Methods: This paper involves a longitudinal study in men submitted for obesity surgery at a university tertiary hospital.

11-Deoxycorticosterone Producing Adrenal Hyperplasia as a Very Unusual Cause of Endocrine Hypertension: Case Report and Systematic Review of the Literature.

Background And Objectives: 11-deoxycorticosterone overproduction due to an adrenal tumor or hyperplasia is a very rare cause of mineralocorticoid-induced hypertension. The objective is to provide the most relevant clinical features that clinicians dealing with patients presenting with the hallmarks of hypertension due to 11-deoxycorticosterone-producing adrenal lesions should be aware of.

Design And Methods: We report the case of a patient with an 11-deoxycorticosterone-producing adrenal lesion and provide a systematic review of all published cases (PubMed, Web of Science and EMBASE) between 1965 and 2021.

Phase angle by electrical bioimpedance is a predictive factor of hospitalisation, falls and mortality in patients with cirrhosis.

The phase angle is a versatile measurement to assess body composition, frailty and prognosis in patients with chronic diseases. In cirrhosis, patients often present alterations in body composition that are related to adverse outcomes. The phase angle could be useful to evaluate prognosis in these patients, but data are scarce.

Comprehensive Genetic Testing of : A Retrospective Analysis in Patients with Suspected Congenital Adrenal Hyperplasia.

The most common form of congenital adrenal hyperplasia (CAH) results from a deficiency of the 21-hydroxylase enzyme (21-OHD), presenting with a broad spectrum of clinical phenotypes according to the gene mutations. Of the 59 patients with suspected CAH, 62.7% presented a positive genetic result.

Frailty in outpatients with cirrhosis: A prospective observational study.

Background And Aim: Frailty is increasingly recognized as a major prognostic factor in cirrhosis in addition to conventional liver insufficiency scores. The aim was to compare the prevalence and characteristics of frailty between patients with cirrhosis and controls, and to analyse its prognostic value.

Methods: We included outpatients with cirrhosis and age- and gender-matched non-cirrhotic controls.

Web Support for Weight-Loss Interventions: PREDIRCAM2 Clinical Trial Baseline Characteristics and Preliminary Results.

An ongoing clinical trial is testing the efficacy of web telematic support in a structured program for obesity treatment and diabetes prevention. Participants were recruited from two tertiary-care hospitals and randomized to receive either a telematic intervention (TI) supported by PREDIRCAM2 web platform or a non-telematic intervention (NTI). All receive 1-year follow-up.

Affective alterations in patients with Cushing's syndrome in remission are associated with decreased BDNF and cortisone levels.

Objective: Affective alterations and poorer quality of life often persist in patients with Cushing's syndrome (CS) in remission. Brain-derived neurotrophic factor (BDNF) regulates the hypothalamic-pituitary-adrenal axis (HPA) and is highly expressed in brain areas controlling mood and response to stress. Our aims were to assess affective alterations after long-term remission of CS and evaluate whether they are associated with serum BDNF, salivary cortisol (SalF) and/or cortisone (SalE) concentrations.

Cystatin-C and epicardial adipose tissue as noninvasive predictors of cardiovascular risk in acromegaly.

Background: Acromegaly (ACRO) is associated with elevated cardiovascular risk, although the prevalence of coronary artery disease (CAD) is unclear. Increased epicardial adipose tissue (EAT) and elevated cystatin-C (Cys-C) levels are cardiovascular risk factors, also related to the progression of CAD in several populations.

Aims: To measure the severity and extent of CAD in patients with ACRO and to determine whether either EAT or Cys-C reflect higher cardiovascular risk in patients with ACRO than in healthy controls.

Pituitary response profile following metoclopramide administration in women with different forms of hyperprolactinemia.

Aims: To test the hypothesis that macroprolactinemia is an extra-pituitary phenomenon by showing that the pituitary production of prolactin in patients with hyperprolactinemia due to macroprolactin is comparable to that in normoprolactinemic women and different from that in women with monomeric hyperprolactinemia.

Methods: Twenty-five women were studied: eight with macroprolactin hyperprolactinemia, eight with monomeric hyperprolactinemia, and nine controls. Prolactin levels were measured before and after precipitation with polyethylene glycol at baseline and at 5, 10,15, 30, and 60 min after metoclopramide administration (10 mg i.

Relative adrenal insufficiency in severe acute variceal and non-variceal bleeding: influence on outcomes.

Background & Aims: Relative adrenal insufficiency (RAI) is common in critical illness and in cirrhosis, and is related with worse outcomes. The prevalence of RAI may be different in variceal and non-variceal bleeding and whether it may influence outcomes in these settings is unclear. This study assesses RAI and its prognostic implications in cirrhosis with variceal bleeding and in peptic ulcer bleeding.

Objective: To study prospectively the utility of the K-ras gene mutation and cytology in the diagnosis and screening of PC, and to assess its contribution to clinical decision making.

Prospective evaluation of the contribution of K-ras mutational analysis and CA 19.9 measurement to cytological diagnosis in patients with clinical suspicion of pancreatic cancer.

The aim of this study was to prospectively evaluate the diagnostic contribution of the detection of K-ras mutation and measurement of serum CA 19.9 concentrations to cytological diagnosis in patients with clinical suspicion of pancreatic cancer. These patients had either the presence or absence of a pancreatic mass as determined by imaging procedures.

Transient pituitary hypothyroidism in a patient with ectopic adrenocorticotrophic hormone secretion.

We report the case of a 55-year-old woman who presented with hypercortisolism secondary to ectopic adrenocorticotrophic hormone secretion and severe non-thyroidal illness syndrome (NTIS) due to metastatic small cell lung carcinoma associated with severe infections. The patient initially showed hormonal profiles of pituitary hypothyroidism and gonadal hypofunction. After decrease in cortisol production following treatment with chemotherapy and metyrapone, serum thyroid hormones and thyroid-stimulating hormone (TSH) concentrations normalized.

A highly sensitive method for K-ras mutation detection is useful in diagnosis of gastrointestinal cancer.

Detection of molecular features such as K-ras mutations has been used to evaluate potential tumour markers in a wide variety of clinical samples. Here we have applied a recently developed highly sensitive method for detection of K-ras codon 12 mutations to colorectal and pancreatic cancer diagnosis. We analysed 67 faecal samples from patients undergoing diagnostic colonoscopy under suspicion of colorectal cancer.
