Antiproliferative and Morphological Effects of Fenretinide Lipid Nanosystems in Colon Adenocarcinoma Cells.

Colon adenocarcinoma is characterized by the downregulation of the retinoic acid receptor, making natural retinoids such as all-trans retinoic acid, 9-cis retinoic acid and 13-cis retinoic acid effective in treatment and chemoprevention due to their ability to increase RARβ expression. However, major limitations to their use include tolerability and acquired resistance. In this study, we evaluated fenretinide, a semisynthetic derivative of all-trans retinoic acid, in an HT-29 cell line.

Diabetic Foot Osteomyelitis in Patients with and without Peripheral Arterial Disease: Two Different Diseases?

The aim of the current study was to evaluate the outcomes of patients with diabetic foot osteomyelitis (DFO), comparing subjects with and without peripheral arterial disease (PAD). The study is a prospective study including a population of patients affected by a DFO located in the forefoot. All patients were managed by a surgical conservative approach defined by the removal of the infected bone, in association with the antibiotic therapy.

Nanomedicine in the Treatment of Diabetes.

Nanomedicine could improve the treatment of diabetes by exploiting various therapeutic mechanisms through the use of suitable nanoformulations. For example, glucose-sensitive nanoparticles can release insulin in response to high glucose levels, mimicking the physiological release of insulin. Oral nanoformulations for insulin uptake via the gut represent a long-sought alternative to subcutaneous injections, which cause pain, discomfort, and possible local infection.

Does the Relationship of the Autonomic Symptoms Questionnaire COMPASS 31 with Cardiovascular Autonomic Tests Differ between Type 1 and Type 2 Diabetes Mellitus?

Backgruound: The aim was to investigate if autonomic symptoms questionnaire Composite Autonomic Symptom Score (COMPASS) 31 has different association with cardiovascular autonomic neuropathy (CAN) and diagnostic performance between type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM).

Methods: Seventy-nine participants with T1DM and 140 with T2DM completed COMPASS 31 before cardiovascular reflex tests (CARTs) for CAN, and assessment of symptoms, signs, vibration, and thermal perception thresholds for diabetic polyneuropathy (DPN) diagnosis.

Results: COMPASS 31 total weighted score (TWS) was similar in the two groups, but significantly associated with confirmed CAN only in T1DM (P=0.

The aim of the current study was to evaluate the rate of readmission in patients affected by diabetes and foot ulcers (DFUs), and causes and outcomes of patients requiring a new hospitalization. The current study is a retrospective observational study including patients who have required hospitalization since January 2019 to September 2022 due to a DFU. Once patients were discharged, they were regularly followed as outpatients.

Peripheral Blood Mononuclear Cells: A New Frontier in the Management of Patients with Diabetes and No-Option Critical Limb Ischaemia.

The current study aimed to evaluate the effectiveness of peripheral blood mononuclear cell (PB-MNC) therapy as adjuvant treatment for patients with diabetic foot ulcers (DFUs) and no-option critical limb ischaemia (NO-CLI). The study is a prospective, noncontrolled, observational study including patients with neuro-ischaemic DFUs and NO-CLI who had unsuccessful revascularization below the ankle (BTA) and persistence of foot ischaemia defined by TcPO2 values less than 30 mmHg. All patients received three cycles of PB-MNC therapy administered through a "" in the affected foot along the wound-related artery according to the angiosome theory.

Prevalence and risk of new-onset diabetes mellitus after COVID-19: a systematic review and meta-analysis.

Aims: After the acute phase of SARS-CoV-2 infection, the onset of glycemic impairment and diabetes have been reported. Nevertheless, the exact burden of glycemic impairment and diabetes after COVID-19 has not been clearly described.

Materials And Methods: Electronic search was run in Pubmed (MEDLINE), Web of Science, Scopus, and ClinicalTrial.

A multidisciplinary team reduces in-hospital clinical complications and mortality in patients with diabetic foot ulcers.

Aims: The current study aims to evaluate the effectiveness of a multidisciplinary diabetic foot team (MDFT) in the management of in-patients affected by diabetic foot problems.

Materials And Methods: The study was a retrospective observational study. Consecutive patients with a diabetic foot problem requiring hospitalisation were included.

Prevalence of Cardiovascular Risk Factors and Coronary Angiographic Findings in High-Risk Immigrant Communities in Italy.

Background: The prevalence of coronary artery disease (CAD) considerably varies by ethnicity. High-risk populations include patients from Eastern Europe (EEP), the Middle East and North Africa (MENAP) and South Asia (SAP).

Methods: This retrospective study aims to highlight cardiovascular risk factors and specific coronary findings in high-risk immigrant groups.

Surgical treatment of post-menopausal ovarian hyperandrogenism improves glucometabolic profile alongside clinical hirsutism.

Hyperandrogenism during menopause is often underestimated by clinicians and attributed to the natural aging process. Hyperandrogenism can be associated with some metabolic abnormalities linked together in a vicious circle by insulin resistance. We present the case of an elderly woman affected with type 2 diabetes and obesity who reported the occurrence of clinical hirsutism after physiological menopause at the age of 47 years.

Microbiological and Clinical Characteristics of Infected Diabetic Foot Ulcers Managed in a Tertiary Level Diabetic Foot Service.

The study aimed to evaluate the clinical and microbiological characteristics of diabetic foot infections (DFIs) in patients referring to a specialized diabetic foot service (DFS). The study is a retrospective observational study conducted in a single center, including patients who were referred for a new DFI. All patients were managed through a limb salvage protocol according to international guidelines.

Geographic and Ethnic Inequalities in Diabetes-Related Amputations.

Individuals with diabetes mellitus are at increasing risk for major lower-extremity amputations (LEAs). Poor quality of life and remarkable disabilities are associated with LEAs, determining a high economic burden for the healthcare systems. Reducing LEAs is therefore a primary marker of quality of care of the diabetic foot.

Insulin Resistance and Acne: The Role of Metformin as Alternative Therapy in Men.

The association between acne and insulin resistance has not been investigated as thoroughly in males as it has been in women, despite the fact that in adult men, acne prevalence has grown. On the face, sebaceous glands produce and secrete sebum, which lubricates the skin and protects it from friction. Metformin, an insulin-sensitizing medication, may modify the association between acne vulgaris and insulin resistance (IR).

Recent Pharmacological Options in Type 2 Diabetes and Synergic Mechanism in Cardiovascular Disease.

Diabetes Mellitus is a multifactorial disease with a critical impact worldwide. During prediabetes, the presence of various inflammatory cytokines and oxidative stress will lead to the pathogenesis of type 2 diabetes. Furthermore, insulin resistance and chronic hyperglycemia will lead to micro- and macrovascular complications (cardiovascular disease, heart failure, hypertension, chronic kidney disease, and atherosclerosis).

Hypocalcemia is associated with adverse outcomes in patients hospitalized with COVID-19.

Purpose: Calcium ions are involved in the regulation of several cellular processes and may also influence viral replication. Hypocalcemia has been frequently reported during infectious diseases and in critically ill patients, including also COVID-19 patients, significantly related with the pro-inflammatory state and mortality. The aim of this study is to investigate the prevalence of hypocalcemia at admission in patients hospitalized for COVID-19 (Coronavirus disease 2019) and to evaluate association of hypocalcemia with in-hospital COVID-19 outcomes.

The New Role of SGLT2 Inhibitors in the Management of Heart Failure: Current Evidence and Future Perspective.

The sodium-glucose transporter 2 inhibitors (SGLT2i) are a relatively new class of medication used in the management of type 2 diabetes. Recent clinical trials and research have demonstrated this class's effectiveness in treating heart failure, since they reduce the risk of cardiovascular events, hospitalization, and mortality. The mechanism by which they do so is unclear; however, SGLT2i inhibit the tubular reabsorption of glucose, lowering the interstitial volume.

Peroxiredoxin 6 Modulates Insulin Secretion and Beta Cell Death a Mitochondrial Dynamic Network.

In pancreatic beta cells, mitochondrial metabolism controls glucose-stimulated insulin secretion (GSIS) by ATP production, redox signaling, and calcium (Ca) handling. Previously, we demonstrated that knockout mice for peroxiredoxin 6 ( ), an antioxidant enzyme with both peroxidase and phospholipase A2 activity, develop a mild form of diabetes mellitus with a reduction in GSIS and in peripheral insulin sensitivity. However, whether the defect of GSIS present in these mice is directly modulated by Prdx6 is unknown.

Activation of Peripheral Blood Mononuclear Cells and Leptin Secretion: New Potential Role of Interleukin-2 and High Mobility Group Box (HMGB)1.

Activation of innate immunity and low-grade inflammation contributes to hyperglycemia and an onset of Type 2 Diabetes Mellitus (T2DM). Interleukin-2 (IL-2), leptin, High Mobility Group Box-1 (HMGB-1), and increased glucose concentrations are mediators of these processes also by modulating peripheral blood mononuclear cells (PBMCs) response. The aim of this study was to investigate if HMGB-1 and IL-2 turn on PBMCs and their leptin secretion.
