Multiple basal infusion rates in open-loop insulin delivery systems: is there a metabolic benefit?

Objective: To evaluate glycemic control according to the number of daily basal rates (BRs) in type 1 diabetes patients using continuous subcutaneous insulin infusion (CSII).

Subjects And Methods: Cross-sectional study of patients treated with an open-loop CSII for at least 6 months and using a flash glucose monitoring system. Patients were divided into 2 groups: group 1 (G1) and group 2 (G2), with ≤4 and >4 BRs/24h, respectively.

[Endocrinopathies Associated with Immune Checkpoint Inhibitors].

Introduction: Immune checkpoint inhibitors (ICIs) are monoclonal antibodies that increase the efficiency of the immune system in the destruction of neoplastic cells. In recent years, these drugs have been increasingly used in the treatment of many neoplasms in advanced stages. However, the change in the regulation of the immune system induced by these drugs has the potential adverse effect of inducing autoimmunity in practically all organ systems.

Flash glucose monitoring system: impact on glycemic control and body mass index in type 1 diabetes mellitus.

Objective: Flash glucose monitoring (FGM) is increasingly used in type 1 diabetes mellitus (T1D) management. This study aimed to assess glycated hemoglobin (HbA1c) and body mass index (BMI) in the first year of FGM use in patients with T1D and to identify predictive factors of benefit associated with its use.

Methods: Retrospective study of T1D patients, using FGM for ≥ 6 months and under intensive insulin therapy with multiple daily injections.

Nearly fatal hypokalaemia due to non-hypertensive primary hyperaldosteronism in the post partum.

A previously healthy postpartum 33-year-old woman was admitted at the emergency department after two episodes of syncope. In the waiting room, she collapsed, ventricular fibrillation was detected, and she was reanimated by electric cardioversion. At admission, she was conscient, with blood pressure of 102/74 mm Hg and heart rate of 78 bpm.

Addison's Disease: A Diagnosis Easy to Overlook.

Addison's disease is a rare and potentially life-threatening clinical condition that often presents with an insidious onset of nonspecific symptoms and signs, frequently resulting in a significant delay in diagnosis. Clinical presentation usually includes fatigue and electrolyte imbalance disorders such as hyponatremia. However, specific diagnostic features, such as hyperpigmentation, should raise clinical suspicion.

Gestational diabetes mellitus: different management strategies should be adopted for different subsets of patients diagnosed by oral glucose tolerance test.

Purpose: To compare women diagnosed with gestational diabetes mellitus (GDM) according to the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) diagnostic criteria based on the number of OGTT diagnostic criteria, which OGTT parameters are altered and the glycemic deviation from proposed diagnostic cutoffs.

Methods: Cross-sectional, multicentric study of women diagnosed with GDM between 24-28 weeks of pregnancy according to the IADPSG criteria, in Portugal, between 2012-2014. Primary outcomes: large for gestational age (LGA) and maternal glucose metabolism status after delivery.

Macroprolactinomas: longitudinal assessment of biochemical and imaging therapeutic responses.

Purpose: To assess biochemical and imaging therapeutic response rates, when these occur and their predictive factors in patients with macroprolactinomas treated with dopamine agonists (DA).

Methods: Retrospective, longitudinal study of patients with macroprolactinomas treated with DA for ≥12 months.

Outcomes: prolactin normalization, reduction in maximum tumor diameter ≥50% and time until therapeutic responses.

Statin-related myotoxicity.

Statin therapy has a very important role in decreasing cardiovascular risk, and treatment non-compliance may therefore be a concern in high cardiovascular risk patients. Myotoxicity is a frequent side effect of statin therapy and one of the main causes of statin discontinuation, which limits effective treatment of patients at risk of or with cardiovascular disease. Because of the high proportion of patients on statin treatment and the frequency of statin-related myotoxicity, this is a subject of concern in clinical practice.

Papillary thyroid carcinoma: different clinical behavior among pT3 tumors.

pT3 papillary thyroid carcinoma (PTC) can be divided into three subgroups according to the largest diameter >4 cm or evidence of minimal extrathyroidal extension (ETE): A >4 cm, no ETE; B ≤4 cm, with ETE; and C >4 cm, with ETE. The aim of this study was to analyze whether these subgroups are clinically different. A retrospective analysis of clinicopathological data of patients with pT3 PTC, with a minimum follow-up of 2 years, at a referral center was conducted.

[Vitamin D Insufficiency in a Hospital Population: A Photograph from the Laboratory Perspective].

Introduction: Although vitamin D deficiency is increasingly recognized around the world, there are few studies on the Portuguese reality. This study aims to analyse vitamin D levels in the assays performed in our hospital and their relationship with age, genre, requesting specialty and moment of sample collection.

Material And Methods: Cross-sectional study of measurements of 25(HO)D performed in our Hospital between June 2012 and November 2014.

Ten-year follow-up of a giant prolactinoma.

Giant prolactinomas are rare pituitary tumours of which management can be a challenge. A 28-year-old man presented with headaches, visual impairment and behavioural changes. Clinically, the patient was found to have hypogonadism and bitemporal hemianopsia.
