Time in Range Analysis in Automated Insulin Delivery Era: Should Day and Nighttime Targets be the Same?

Introduction: Hybrid closed-loop systems (HCLS) use has shown that time in range (TIR) tends to improve more during the nighttime than during the day. This study aims to compare the conventional TIR, currently accepted as 70 to 180 mg/dL, with a proposed recalculated time in range (RTIR) considering a tighter glucose target of 70 to 140 mg/dL for the nighttime fasting period in T1DM patients under HCLS.

Methods: We conducted a retrospective study that included adults patients receiving treatment with Tandem t:slim X2 Control-IQ.

Efficacy and safety of SGLT2 inhibitors in individuals with type 1 diabetes under continuous subcutaneous insulin infusion: a real-world study.

Adjuvant therapy with sodium-glucose cotransport 2 inhibitors (SGLT2i) in type 1 diabetes (T1D) is associated with an improvement in glycemic control, but increases the risk of diabetic ketoacidosis (DKA). However, real-life studies in individuals with T1D under continuous subcutaneous insulin infusion (CSII) are still scarce. We present the first real-life study performed in patients with T1D exclusively treated with CSII.

Application of the New "Points in Range" Metrics in the Assessment of In-Hospital Glycemic Control.

Introduction Capillary blood glucose (CBG) monitoring remains the most used testing form in hospitals and allows for "points in range (PIR)" metric calculation. This study was conceived to evaluate the metabolic control in patients with diabetes mellitus (DM) at a hospital through PIR metrics. Methods This was an observational cross-sectional study conducted on October 9, 2020, that included non-critical adults admitted to Centro Hospitalar Universitário do Porto (except pregnant/postpartum women) with DM under CBG monitoring and a minimum of 24 hours of hospitalization.

Maturity-onset diabetes of the young in a large Portuguese cohort.

Aims: Monogenic forms of diabetes that develop with autosomal dominant inheritance are classically aggregated in the Maturity-Onset Diabetes of the Young (MODY) categories. Despite increasing awareness, its true prevalence remains largely underestimated. We describe a Portuguese cohort of individuals with suspected monogenic diabetes who were genetically evaluated for MODY-causing genes.

Pituitary adenomas in the elderly: Retrospective comparative analysis of clinical/tumor features and surgical data by age group.

The increase in life expectancy along with technological advances has translated into a higher number of pituitary adenomas (PA) diagnosed from the age of 65. In the elderly, symptoms related to comorbidities might overlap with endocrine dysfunction, in addition to increasing anesthetic and surgical risks. This study aimed to compare baseline clinical and tumor features between patients with PA from different age groups: younger adults (YA), 18 to 64 years, and older adults (OA), ≥65 years.

Faster Insulin Aspart for Continuous Subcutaneous Insulin Infusion: Is It Worth It?

Introduction Faster insulin aspart (fASP) is the new formulation of insulin aspart (ASP) with a left-shifted pharmacokinetic profile, allowing better control of early postprandial hyperglycemia and a reduction in the risk of late post-meal hypoglycemia. However, it can be associated with more frequent infusion set changes. The purpose of this study is to evaluate efficacy and safety one, three, and six months after starting fASP in continuous subcutaneous insulin infusion (CSII) systems.

MODY probability calculator utility in individuals' selection for genetic testing: Its accuracy and performance.

Introduction: MODY probability calculator (MPC) represents an easy-to-use tool developed by Exeter University to help clinicians prioritize which individuals should be oriented to genetic testing. We aimed to assess the utility of MPC in a Portuguese cohort with early-onset monogenic diabetes.

Methods: This single-centre retrospective study enrolled 132 participants submitted to genetic testing between 2015 and 2020.

Impact of intermittently scanned continuous glucose monitoring on quality of life and glycaemic control in persons with type 1 diabetes: A 12-month follow-up study in real life.

Background And Aim: We sought to prospectively assess the impact of intermittently scanned continuous glucose monitoring (isCGM) initiation in the glycaemic control and quality of life (QoL) in type 1 diabetes mellitus (T1DM) patients followed in real-live conditions.

Methods: Prospective, observational, cohort, single-centre and single-arm study conducted between September 2018 and March 2020, enrolling adults with T1DM with at least one year of diagnosis, interested in using isCGM. After training at isCGM initiation, CGM metrics and QoL were assessed at baseline and 12 months.

LAMP2A regulates the loading of proteins into exosomes.

Exosomes are extracellular vesicles of endosomal origin that are released by practically all cell types across metazoans. Exosomes are active vehicles of intercellular communication and can transfer lipids, RNAs, and proteins between different cells, tissues, or organs. Here, we describe a mechanism whereby proteins containing a KFERQ motif pentapeptide are loaded into a subpopulation of exosomes in a process that is dependent on the membrane protein LAMP2A.

Case Report: Pheochromocytoma and Synchronous Neuroblastoma in a Family With Hereditary Pheochromocytoma Associated With a MAX Deleterious Variant.

Introduction: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumours arising from chromaffin cells of the adrenal medulla or extra-adrenal sympathetic paraganglia. Recent studies have indicated that up to 40% of pheochromocytomas could be attributable to an inherited germline variant in an increasing list of susceptibility genes. Germline variants of the MYC-associated factor () gene have been associated with familial pheochromocytomas and paragangliomas with an autosomal dominant pattern of inheritance, a median age at onset of 33 years and an overall frequency estimated at 1.

Predicting dye biodegradation from redox potentials.

Two biological approaches for decolorization of azo sulfonated dyes have been compared: reductive decolorization with the ascomycete yeast Issatchenkia occidentalis and enzymatic oxidative decolorization with Trametes villosa laccase alone or in the presence of the mediator 1-hydroxybenzotriazole. The redox potential difference between the biological cofactor involved in the reductive activity of growing cells and the azo dye is a reliable indication for the decolorization ability of the biocatalyst. A linear relationship exists between the redox potential of the azo dyes and the decolorization efficiency of enzyme, enzyme/mediator, and yeast.
