Introduction: Bioelectrical Impedance Analysis (BIA) is a tool used in clinical nutrition and pure electrical data such as phase angle (PA) has shown prognostic value. It relates resistance and reactance indicating cellular health.

Objective: To determine differences in PA between patients with obesity and disease-related malnutrition (DRM) compared to the healthy population, and to establish associations between PA and other body composition (BC) parameters.

Materials and methods: Retrospective observational study with 1079 patients from the Obesity and Nutrition Department of the Complejo Asistencial Universitario de León between April/2014 and August/2022 as well as 86 healthy controls. Demographic and anthropometric variables were collected and BC was performed with BIA Tanita MC780®. Diagnosis of malnutrition according to GLIM criteria and obesity with body mass index (BMI).

Results: PA50KHz in obesity group is 5.98º, DRM 4.79º and control group 6.08º. Statistically significant differences in PA between DRM and control groups, as well as DRM and obesity (p < 0.001). Weak positive correlation in total population (r = 0.452, p < 0.001) as well as control group (r = 0.463, p < 0.001) between BMI and PA. Weak negative correlation in the total population (r = -0.408, p < 0.001), DRM (r = -0.268, p < 0.001) and obesity (r = -0.342, p < 0.001) between age and PA.

Conclusions: In this study, significantly lower PA was observed in the DRM group than in the control and obesity groups. No statistically significant differences between PA in the obesity and control groups and no correlation between BMI and PA in the obesity group. More studies are needed to standardize cut-off points in different contexts and populations.

At present, the majority of patients with type 1 diabetes mellitus do not achieve the recommended glycemic control goals to reduce the risk of acute and chronic complications. Hybrid closed-loop systems or automated insulin infusion systems emerged as an opportunity to improve metabolic control, quality of life and reduce the psychosocial impact of type 1 diabetes. This article analyzes the evidence regarding their effectiveness and safety, the challenges they pose and best practices to optimize results when implemented in clinical practice.

Background and objective: The high incidence of thyroid nodular disease has raised concerns on the therapeutic management of benign thyroid nodules. The development of minimally invasive techniques is an alternative to surgery and has a low rate of complications. Our objective was to evaluate the safety and efficacy profile of percutaneous ethanol injections (PEI) with ethanol aspiration of symptomatic cystic and predominantly cystic thyroid nodules (cystic component > 50%) treated in the thyroid nodule high-resolution unit (TNHRU) of Hospital de Tortosa Verge de la Cinta Hospital, Tarragona, Spain.

Patients and methods: The present work is a prospective, observational and descriptive study of 32 patients (87.5% women, mean age of 43; SD, 12) evaluated at the TNHRU from August 2022 through December 2023. Demographic data such as age, sex, previous thyroid function, diagnostic method, initial nodular volume, nodular composition and nodular location were analyzed. Using ultrasounds, measurements of diameters and thyroid nodule volume were taken. We aspirated a total of 50% of the cystic content and injected between 2 mL and 5 mL of 99% ethanol (depending on cystic volume). After letting the ethanol act inside the nodule for 5 to 10 minutes, all the cystic content and the injected ethanol were aspirated. We performed an ultrasound follow-up at 1, 3 and 6 months, calculating the total volume and the volume reduction rate (VRR). The impact on health-related quality of life (HRQoL) was assessed using the ThyPRO-39es questionnaire, which was administered before and after the PEI treatment at the 6-month follow-up.

Results: The median volume reduction at the end of the 6-month follow-up was 0.23 mL (0.00-0.67), and the VRR, 98.57% (94.80-100.00). The difference between the initial volume and the mean volume at the 1-, 3-, and 6-month follow-ups was statistically significant, as was the VRR between the 1-month and the 3- and 6-month follow-ups. Six patients (18.80%) required 2 PEIs and only 2 patients (6.3%) required 3 PEIs. The overall quality of life, which was scored from 0 (good) to 4 (poor), significantly improved from 1.28; SD, 0.81 up to 0.19; SD, 0.40 (p < 0.001).

Conclusions: PEI is an effective alternative to treat cystic thyroid nodules resulting in an improved patients' HRQoL. It can be performed outpatiently with a low rate of complications, thus making it suitable for inclusion in the service portfolio of a HRTNU.

Introduction: Automatic insulin delivery (AID) systems improve glycemic control and quality of life in individuals with type 1 diabetes (T1D). Our aim was to assess the feasibility, effectiveness, and safety of switching from a sensor-augmented pump (SAP) to AID in T1D subjects at high risk of hypoglycemia.

Materials and methods: A manufacturer-led program consisting of three sessions was implemented. Over three days, all patients completed the first session in-person, in groups of 6-12 people, to receive device training. Subsequently, the automatic mode was activated virtually (session 2), followed by online data download (session 3). Glucometric outcomes were evaluated after one month, along with serious adverse events (SAEs), technical incidents, and perceived satisfaction.

Results: The switch was performed in 125 patients, 56.8% of whom were women, with a mean age of 44.1 ± 14.9 years. 99.2% (n = 124) initialized auto-mode. There was an increase in time in range 70-180 mg/dL (64.3 ± 11.3 vs. 74.7 ± 11.2; p < 0.001) and a decrease in time below 70 mg/dL (4.1 ± 3.9 vs. 2.0 ± 1.8; p < 0.001) (N = 97). Forty-one related calls were received, with 10 requiring in-person visits. Medtronic technical service handled 92 related calls (0.74 per patient), from 47 different users (37.6%). One event of severe hypoglycemia was recorded as an SAE. Perceived security and satisfaction with the switch process were high in 91% and 92% of patients, respectively.

Conclusions: Massive switch from SAP to AID in T1D patients at high risk of hypoglycemia is feasible and safe through a hybrid program conducted in collaboration with the manufacturer.
