Peer Support as Part of Scaling-Up Integrated Care in Patients with Type 2 Diabetes and Arterial Hypertension at the Primary Healthcare Level: A Study Protocol.

Introduction: Type 2 diabetes (T2D) and arterial hypertension (AH) are among the greatest challenges facing health systems worldwide and require comprehensive patient-centred care. The key to successful management in chronic patients is self-management support, which was found to be only weakly implemented in Slovenia. The aim of the study is to develop an evidence-based model of peer support for people with T2D and AH at the primary healthcare level in Slovenia, which could represent a potential solution for upgrading integrated care for these patients. Methods: A prospective interventional, mixed-methods pilot study will begin by recruiting approximately 40 eligible people with T2D and AH through purposive sampling. The participants will receive structured training, led by a specialist nurse, to become trained peer supporters. Each will voluntarily share their knowledge and experience at monthly group meetings with up to 10 people with T2D and AH over a three-month period in the local community. Data will be collected through interviews and focus groups and questionnaires about socio-demographic and clinical data, knowledge about T2D and AH, participants' quality of life, level of empowerment and acceptability of the intervention. Expected results: The study will provide an evidence-based model for integrating peer support into the local community. It is expected that the intervention will prove feasible and acceptable with educational, psychosocial and behavioural benefits. Conclusion: Peer support through empowerment of people with T2D and AH, family members and other informal caregivers in the local community could scale-up the integrated care continuum and contribute to sustainability of the healthcare system.

Telemonitoring of Elderly with Hypertension and Type 2 Diabetes at the Primary Care Level: Protocol for a Multicentric Randomized Controlled Pilot Study.

Introduction: Arterial hypertension (AH) and type 2 diabetes (T2D) represent a significant burden for the public health system, with an exceptionally high prevalence in patients aged ≥65 years. This study aims to test the acceptability, clinical effectiveness, and cost-effectiveness of telemonitoring in elderly patients with AH and T2D at the primary care level. Methods: A m ulti-centre, prospective, randomized, controlled t rial w ill be conducted. Patients a ged ≥ 65 y ears with AH and T2D will be randomized in a 1:1 proportion to a mHealth intervention or standard care group. Patients in the intervention group will measure their blood pressure (BP) twice weekly and blood glucose (BG) once monthly. The readings will be synchronously transmitted via a mobile application to the telemonitoring platform, where they will be reviewed by a general practitioner who will indicate changes in measurement regimen or carry out a teleconsultation. The primary endpoint will be a change in systolic BP (SBP) and glycated haemoglobin (HbA1c) relative to standard care up to 12 months after inclusion. Secondary endpoints will be a change in other observed clinical variables, quality-of-life indexes, and costs. Expected results: Telemonitoring will be an acceptable method of care associated with significant reductions in SBP and HbA1c levels and an increase in quality-of-life indexes in the intervention group. However, the cost-effectiveness threshold (incremental cost-effectiveness ratio below €25,000/quality-adjusted life year) might not be reached. Conclusion: This study will provide new evidence for scaling up telemonitoring network at the primary care level and modifying telemonitoring protocols to achieve the best clinical and cost-effective outcomes.

L-arginine as dietary supplement for improving microvascular function.

BACKGROUND: Reduced availability of nitric oxide leads to dysfunction of endothelium which plays an important role in the development of cardiovascular diseases. OBJECTIVE: The aim of the present study was to determine whether the dietary supplement L-arginine improves the endothelial function of microvessels by increasing nitric oxide production. METHODS: We undertook experiments on 51 healthy male volunteers, divided into 4 groups based on their age and physical activity since regular physical activity itself increases endothelium-dependent vasodilation. The skin laser Doppler flux was measured in the microvessels before and after the ingestion of L-arginine (0.9 g). The endothelium-dependent vasodilation was assessed by acetylcholine iontophoresis and the endothelium-independent vasodilation by sodium nitroprusside iontophoresis. In addition, we measured endothelium-dependent and endothelium-independent vasodilation in 81 healthy subjects divided into four age groups. RESULTS: After the ingestion of L-arginine, the endothelium-dependent vasodilation in the young trained subjects increased (paired t-test, p < 0.05), while in the other groups it remained the same. There were no differences in the endothelium-independent vasodilation after ingestion of L-arginine. With aging endothelium-independent vasodilation decreased while endothelium-dependent vasodilation remained mainly unchanged. CONCLUSION: Obtained results demonstrated that a single dose of L-arginine influences endothelium-dependent vasodilation predominantly in young, trained individuals.
