How should we differentiate hypoglycaemia in non-diabetic patients?

Hypoglycaemic syndromes are rare in apparently healthy individuals and their diagnosis can be a difficult challenge for clinicians as there are no shared guidelines that suggest how to approach patients with a suspect hypoglycaemic disorder. Since hypoglycaemia symptoms are common and nonspecific, it's necessary to document the Whipple Triad (signs and/or symptoms compatible with hypoglycaemia; relief of symptoms following glucose administration; low plasma glucose levels) before starting any procedure. Once the triad is documented, a meticulous anamnesis and laboratory tests (blood glucose, insulin, proinsulin, C-peptide, β-hydroxybutyrate and anti-insulin antibodies) should be performed.

A guide for the use of LibreView digital diabetes platform in clinical practice: Expert paper of the Italian Working Group on Diabetes and Technology.

Wider access to continuous glucose monitoring systems, including flash glucose monitoring, has enabled people with diabetes to achieve lower HbA1c levels and reduce the amount of time they spend in hypoglycaemia or hyperglycaemia, and has improved their quality of life. An International Consensus Panel proposed different target glucose ranges and recommendations according to different ages and situations (adults, young people and children with type 1 or type 2 diabetes, as well as elderly people who are at higher risk of hypoglycaemia, and women with diabetes during pregnancy). In this expert opinion, we interpret the international recommendations in the context of established clinical practice for diabetes care, and propose three different step-by-step algorithms to help the healthcare professionals use the most innovative glucose metrics, including time in glucose ranges, glucose management indicator, coefficient of variation, and ambulatory glucose profile.

Safety and feasibility of upper limb cardiopulmonary exercise test in Friedreich ataxia.

Methods And Results: Cardiopulmonary exercise test was performed using an upper limbs cycle ergometer on fasting subjects. Peak oxygen uptake (peak VO2) was recorded as the mean value of VO2 during a 20 s period at the maximal effort of the test at an appropriate respiratory exchange rate.

Management of patients with chronic heart failure and type 2 diabetes mellitus: the SCODIAC-II study.

SCODIAC was a pilot study which revealed an increasing use of SGLT2i in 123 outpatients affected with Heart Failure (HF) and Type 2 Diabetes Mellitus. SCODIAC-II study, the second phase of the program, has been carried out to determine diagnostic and therapeutic pathways in a larger group of patients and to verify whether the use of innovative antidiabetic therapies could modify echocardiographic parameters and cardiovascular therapies. 406 HF-diabetic patients, referred to Cardiologists and Diabetologists of pertaining healthcare districts in Campania, were enrolled in this retrospective study and divided in Group A, composed of 136 patients with preserved Ejection Fraction (HF-pEF)(> 45%) and Group B, formed of 270 patients with reduced EF (HF-rEF)(≤ 45%).

Atorvastatin-linked rhabdomyolysis caused by the simultaneous intake of amoxicillin clavulanic acid.

Objectives Rhabdomyolysis is a rare syndrome in which a serious muscle damage suddenly appears, with the possible occurrence of severe complications such as kidney failure, electrolyte imbalances and death, and represents the most severe form of statin-induced muscle injury. Case presentation Here we present the case of a 55-year-old woman who started therapy with amoxicillin clavulanic acid on a background of atorvastatin therapy, resulting in rhabdomyolysis. Conclusions This case highlights the importance of evaluating potential drug interactions in patients taking statin and the need of monitoring clinical and laboratory findings suggestive of rhabdomyolysis.

Long-term effect of epoetin alfa on clinical and biochemical markers in friedreich ataxia.

Background: Friedreich ataxia is an autosomal recessive disease with no available therapy. Clinical trials with erythropoietin in Friedreich ataxia patients have yielded conflicting results, and the long-term effect of the drug remains unknown.

Methods: We designed a double-blind, placebo-controlled, multicenter trial to test the efficacy of epoetin alfa on 56 patients with Friedreich ataxia.

Migraine attack restores the response of vascular smooth muscle cells to nitric oxide but not to norepinephrine.

Aim: To clarify whether the vasoconstrictory response is impaired and to study vascular function in patients with migraine during the headache attack.

Impaired endothelial- and nonendothelial-mediated vasodilation in patients with acute or chronic hypothyroidism.

Objective: Vascular dysfunction and accelerated atherosclerosis are prominent features of hypothyroidism. The relative roles of thyroid hormone (TH) deficiency and the associated vascular risk conditions are still unclear. We studied the impact of acute and chronic hypothyroidism on vascular reactivity.

Long-term cardiovascular effects of levothyroxine therapy in young adults with congenital hypothyroidism.

Context: Congenital hypothyroidism (CH) is the most prevalent endocrine disorder in the newborn and is routinely treated with life-long levothyroxine replacement therapy. Although several studies have demonstrated that such therapy may impact on the cardiovascular system, little is known with regard to the effects of long-term levothyroxine administration in patients with CH.

Objective: The aim of the current study was to evaluate whether long-term levothyroxine replacement therapy in young adults with CH is associated with cardiovascular abnormalities.

Enhancement of vascular endothelial function by recombinant human thyrotropin.

Context: The cardiovascular consequences of thyroid diseases are attributed to the altered secretion of thyroid hormones. The possibility that TSH also affects the cardiovascular system has been poorly explored. Endothelial cells and vascular smooth muscle cells possess TSH receptors.

Acute effects of triiodothyronine on endothelial function in human subjects.

Context: Thyroid hormone regulates several cardiovascular functions, and low T(3) levels are frequently associated with cardiovascular diseases. Whether T(3) exerts any acute and direct effect on endothelial function in humans is unknown.

Objective: Our objective was to clarify whether acute changes in serum T3 concentration affect endothelial function.

Red wine consumption improves insulin resistance but not endothelial function in type 2 diabetic patients.

Epidemiological studies have shown that red wine consumption is associated with less cardiovascular mortality in the general population and in the diabetic patients. To determine whether red wine improves insulin resistance in diabetic patients and to explore the relation between insulin sensitivity and endothelial function, we studied vascular reactivity and insulin-mediated glucose uptake in 9 type 2 diabetic patients before and after 2 weeks of red wine consumption (360 mL/d, wine-treated diabetics) and 8 type 2 diabetic patients who did not consume wine (control diabetics). Vascular reactivity was evaluated by plethysmography during intraarterial infusion of acetylcholine (Ach), sodium nitroprusside, and L-N-monomethylarginine.

Food and red wine do not exert acute effects on vascular reactivity.

Experimental hyperglycemia and hyperinsulinemia have been shown to affect vascular reactivity. Chronic red wine consumption is associated with less cardiovascular mortality. Whether ingestion of a natural meal and red wine causes acute changes in vascular homeostasis is poorly understood.

Supportive care in patients with advanced non-small-cell lung cancer.

The present study describes supportive care (SC) in patients with advanced non-small-cell lung cancer (NSCLC), evaluating whether it is affected by concomitant chemotherapy, patient's performance status (PS) and age. Data of patients enrolled in three randomised trials of first-line chemotherapy, conducted between 1996 and 2001, were pooled. The analysis was limited to the first three cycles of treatment.

Acute effects of growth hormone on vascular function in human subjects.
