Sodium-Glucose Cotransporter 2 Inhibitors Improve Body Composition by Increasing the Skeletal Muscle Mass/Fat Mass Ratio in Patients with Type 2 Diabetes: A 52-Week Prospective Real-Life Study.

Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2is) induce body weight loss, but their effect on skeletal muscle mass (SMM) and strength needs to be better elucidated.

Objectives: This study aimed to evaluate the effects of SGLT2i on SMM in a real-life population setting of patients with type 2 diabetes (T2D). Secondary outcomes included changes in liver steatosis and in anthropometric and glucometabolic parameters.

A Functional Human Glycogen Debranching Enzyme Encoded by a Synthetic Gene: Its Implications for Glycogen Storage Disease Type III Management.

Background: Glycogen Storage Disease type III (GSD III) is a metabolic disorder resulting from a deficiency of the Glycogen Debranching Enzyme (GDE), a large monomeric protein (approximately 170 kDa) with cytoplasmic localization and two distinct enzymatic activities: 4-α-glucantransferase and amylo-α-1,6-glucosidase. Mutations in the Agl gene, with consequent deficiency in GDE, lead to the accumulation of abnormal/toxic glycogen with shorter chains (phosphorylase limit dextrin, PLD) in skeletal and/or heart muscle and/or in the liver. Currently, there is no targeted therapy, and available treatments are symptomatic, relying on specific diets.

Estimation with Ultimate Quantum Precision of the Transverse Displacement between Two Photons via Two-Photon Interference Sampling Measurements.

We present a quantum sensing scheme achieving the ultimate quantum sensitivity in the estimation of the transverse displacement between two photons interfering at a balanced beam splitter, based on transverse-momentum sampling measurements at the output. This scheme can possibly lead to enhanced high-precision nanoscopic techniques, such as superresolved single-molecule localization microscopy with quantum dots, by circumventing the requirements in standard direct imaging of camera resolution at the diffraction limit, and of highly magnifying objectives. Interestingly, we show that our interferometric technique achieves the ultimate spatial precision in nature irrespectively of the overlap of the two displaced photonic wave packets, while its precision is only reduced of a constant factor for photons differing in any nonspatial degrees of freedom.

Fluorescence lifetime Hong-Ou-Mandel sensing.

Fluorescence Lifetime Imaging Microscopy in the time domain is typically performed by recording the arrival time of photons either by using electronic time tagging or a gated detector. As such the temporal resolution is limited by the performance of the electronics to 100's of picoseconds. Here, we demonstrate a fluorescence lifetime measurement technique based on photon-bunching statistics with a resolution that is only dependent on the duration of the reference photon or laser pulse, which can readily reach the 1-0.

Oral semaglutide improves body composition and preserves lean mass in patients with type 2 diabetes: a 26-week prospective real-life study.

Background: Oral semaglutide is the first glucagon-like peptide-1 receptor agonist (GLP-1RA) designed for oral administration; it offers a promising opportunity to facilitate an early approach to Type 2 Diabetes (T2D). The study aimed to evaluate, in a real-life setting, the effects of oral semaglutide on the body composition of patients with T2D after 26 weeks of therapy.

Methods: Thirty-two patients with T2D were evaluated at baseline (T0) and after three (T3) and six (T6) months of therapy with oral semaglutide.

Hypothyroidism in Older Adults: A Narrative Review.

The prevalence of hypothyroidism increases along with aging, resulting in one of the most common comorbidities among patients over 75 years. The leading causes of hypothyroidism in older adults are iatrogenic, Hashimoto's thyroiditis, and medications. The narrative review aimed to discuss the clinical characteristics of hypothyroidism in older adults and the impact of hormonal replacement therapy on survival rates.

Dyslipidemia and Cardiovascular Prevention in the Elderly: A Balance between Benefits and Risks of Statin Treatment in a Specific Population.

Introduction: Atherosclerotic Cardiovascular Diseases (CVD) are among the most relevant causes of morbidity and mortality worldwide, especially in aged people. Statins are one of the leading pharmacological interventions against atherosclerosis and are widely used to reduce the risk of occurring coronary artery diseases and related outcomes in both primary and secondary prevention. The management of chronic diseases is improved considerably over time, leading to an increase in life expectancy despite heavier comorbidity-related burdens in the elderly.

Endocrine, Metabolic, and Immune Pathogenesis of Postmenopausal Osteoporosis. Is there a Therapeutic Role in Natural Products?

Background: Bone health relies on the equilibrium between resorption and new bone generation. Postmenopausal osteoporosis depends on estrogen deficiency which favorite bone resorption and elevated risk of fractures. Moreover, osteoporosis is characterized by a high release of proinflammatory cytokines suggesting the role of the immune system in the pathogenesis of this complex disease (immunoporosis).

Right Ventricular Dysfunction and Exercise Impairment in Patients with Heart Failure, Insulin Resistance, and Diabetes Mellitus: Insights from the T.O.S.CA. Registry (Cardiovascular Diabetology 2022).

Background: Insulin resistance (IR) and type 2 diabetes mellitus (T2D) are known to affect the progression of chronic heart failure (CHF), but little evidence exists about the impact of IR and T2D on right ventricular dysfunction and exercise tolerance. Insights from the T.O.

Iodine Deficiency and Iodine Prophylaxis: An Overview and Update.

The thyroid gland requires iodine to synthesize thyroid hormones, and iodine deficiency results in the inadequate production of thyroxine and related thyroid, metabolic, developmental, and reproductive disorders. Iodine requirements are higher in infants, children, and during pregnancy and lactation than in adult men and non-pregnant women. Iodine is available in a wide range of foods and water and is susceptible to almost complete gastric and duodenal absorption as an iodide ion.

When Serum C-Peptide Measurement Drives Adequate Diabetes Mellitus Diagnosis and Therapy: A Case Report.

Background: Therapeutic targets in type 2 diabetes mellitus (T2D) are oriented towards nephron- and cardio-protection and the prescription of antihyperglycemic agents with proven renal and cardiovascular benefits are increasing over time. Failure to promptly diagnose insulinopenic diabetes may adversely affect the adequacy of treatment and have harmful consequences, including severe hyperglycemia and diabetic ketoacidosis.

Case Presentation: Herein we present the case of a 57-year-old woman referred to our clinic due to poor glycemic control (HbA1c 80 mmol/mol, therapeutic target <53 mmol/mol), class III obesity (BMI 41 kg/m2; normal value <25 kg/m), and high cardiovascular risk misdiagnosed with T2D several years before.

Once-Weekly Subcutaneous Semaglutide Improves Fatty Liver Disease in Patients with Type 2 Diabetes: A 52-Week Prospective Real-Life Study.

Background: Nonalcoholic fatty liver disease (NAFLD) is commonly observed in patients with type 2 diabetes (T2D). Semaglutide, a glucagon-like peptide 1 receptor agonist, may have a therapeutic role by targeting common mechanisms involved in the pathophysiology of T2D and NAFLD. The study aimed to assess the effectiveness of Semaglutide on NAFLD in patients with T2D.

The need for custom made frozen elephant trunk: when and where.

The frozen elephant trunk (FET) technique is an increasingly common procedure to treat complex extensive aortic disease both in elective and emergency setting. In a contemporary era, several prostheses are available to be used by surgeons performing such procedures, merging the advantages of endovascular and conventional surgery and preparing a more useful landing zone for second-stage downstream endovascular or open repair. Thoraflex hybrid (Terumo Aortic, Scotland) is a largely used hybrid vascular device merging a conventional surgical vascular graft made of gelatin-sealed woven polyester graft with a nitinol self-expanding stent graft.

Frozen Elephant Trunk Technique in Acute Type A Aortic Dissection: Is It for All?

Acute type A aortic dissection (ATAAD) is an indisputable emergency with very poor outcomes without surgical treatment. Although the aortic arch is often involved in the aortic dissection, its optimal management during surgical therapy remains uncertain. A conservative tear-oriented approach has traditionally been adopted, limiting the procedure to the ascending aorta (or hemiarch) replacement.

Surgical removal of an exceedingly rare papillary fibroelastoma of the aortic wall causing unstable angina.

Difficult diagnosis is due to rarity of the case. TT or TE echocardiography is sufficient to make a correct diagnosis. The risk of embolism or coronary ostia occlusion should guide the decision for surgery.

Caged-Ball Mitral Prosthesis Explanted After 50 Years.

We report a unique case of a Starr-Edwards prosthesis (model 6310, cloth covered) implanted in the mitral position by Christian Barnard that was successfully explanted and replaced after 50 years, the longest period free from valve dysfunction ever reported. Reoperation also included replacement of the native aortic valve combined with tricuspid valve annuloplasty. ().

A modified frozen elephant trunk hybrid device to facilitate supra-aortic trunk anastomosis.

Reimplantation of the supra-aortic vessels can be challenging with Thoraflex Hybrid. A device modification made the vessel lengths more appropriate and the position of the neo-vessels in the chest avoided malpositioning and kinking and facilitated sternum closure; this may improve operating times as well as allowing complete and continuous cerebral trivascular perfusion and corrects positioning of the intrathoracic vessels.

Impella 5.0 repositioning across the aortic valve without a guidewire using rapid ventricular pacing: A case report.

Background: Displacement of Impella 5.0 secondary to patient movement or transportation is a well-known complication. Typically, repositioning of an Impella across the aortic valve is attempted over a guidewire.

Expression of a Functional Recombinant Human Glycogen Debranching Enzyme (hGDE) in N. benthamiana Plants and in Hairy Root Cultures.

Background: Glycogen storage disease type III (GSDIII, Cori/Forbes disease) is a metabolic disorder due to the deficiency of the Glycogen Debranching Enzyme (GDE), a large monomeric protein (about 176 kDa) with two distinct enzymatic activities: 4-α-glucantransferase and amylo-α-1,6-glucosidase. Several mutations along the amylo-alpha-1,6-glucosidase,4-alphaglucanotransferase (Agl) gene are associated with loss of enzymatic activity. The unique treatment for GSDIII, at the moment, is based on diet.
