Introduction: The coronavirus pandemic has disproportionately affected older adults and has provided an incentive to find alternatives to emergency department attendance to avoid unnecessary exposure to the SARS-CoV-2 virus. To address this issue, a specialist geriatric multidisciplinary team at Queen Elizabeth Hospital set up a novel telemedicine approach to the ambulance service with the aim of reducing unnecessary emergency department attendance for older adults. This study provides a service evaluation in its first year of use. Methods: Service evaluation in the first year of the ‘Ask OPAL’ (older person Assessment and liaison) hotline for ambulance paramedics, run by a multidisciplinary acute geriatrics team at the Queen Elizabeth Hospital, Birmingham. Data on the number, patient demographics, intervention, and outcome of the calls, were recorded Results: During the study period, 2552 ‘Ask OPAL’ calls were conducted. Of the 2552 calls carried out, 1755 patients (69%) remained at home. Of the patients who remained at home, 76% received verbal advice only, while 24% were referred to community services in addition to receiving verbal advice. Conclusion: In conclusion, the use of an integrated multidisciplinary team communicating with paramedics via telemedicine appears to be successful in preventing avoidable hospital admissions in complex patients.

Background: Diabetes mellitus (DM) is a metabolic disorder characterized by progressive β cell dysfunction. Sheng-Mai Injection (SMI), a Traditional Chinese medicine preparation, is widely used for DM and its related complications. Objective: This meta-analysis aimed to summarize the applications of SMI in DM and related complications. Methods: Eight databases were searched, and meta-analyses were performed. Results: Fifteen studies, including 1273 participants, were included. All studies and participants included were from China. Pooled effects showed that SMI might reduce glycated hemoglobin (MD -0.46%; 95% CI -0.89 to -0.03; P < 0.01), fasting blood glucose (MD -0.83 mmol/L; 95% CI -1.30 to -0.36; P < 0.01), two-hour postprandial glucose (MD -1.27 mmol/L; 95% CI -1.96 to -0.58; P < 0.01), 24-hour urinary protein (MD -0.28 mg; 95% CI -0.51 to -0.06; P = 0.01), blood urea nitrogen (MD -1.31 mg; 95% CI -2.08 to -0.54; P < 0.05), Scr (MD -2.60; 95% CI -3.43 to -1.77; P < 0.05), ulnar nerve motor nerve conduction velocity (MNCV) (MD 1.45; 95% CI 0.03 to 2.87; P < 0.05), and tibial nerve sensory nerve conduction velocity (SNCV) (MD 1.84; 95% CI 0.1 to 3.58; P < 0.05). There was no evidence of an effect on common peroneal nervous MNCV and SNCV, tibial nerve MNCV, median nerve MNCV, and SNCV. Adverse effects included less frequent gastrointestinal reactions, elevated transaminase, leucopenia, fever, and rash. Conclusion: Combination use of SMI based on conventional hypoglycemic treatment can significantly improve HbA1c, FBG, and 2hPG in DM and reduce 24-hour urinary protein, Scr, and BUN in DM patients. SMI was found to have no effect on the neurological function of diabetic peripheral neuropathy.

Background: The Italian population’s habits changed dramatically during the “COVID- 19 lockdown” due to physical distancing and self-isolation. Moreover, medical consultations of patients with chronic diseases, such as type 2 diabetes (T2D), were suspended or postponed, unless urgent or semi-urgent, for several consecutive months. Thus, it is expected that the lockdown could have affected glucometabolic control in T2D. Purpose: The aim of the study was to assess changes in glucometabolic control in a cohort of T2D patients before (T1) and after (T2) the COVID-19 lockdown (March-May 2020). Methods: The study was approved by the Ethics Committee of the University of Bari, and all patients provided informed written consent to participate. Medical history, complete physical examination, and laboratory assessment were conducted as real-life clinical practice. Changes in clinical and laboratory variables between T1 and T2 were calculated. Results: In detail, 13 patients were on metformin as monotherapy, 36 on GLP-1RA, 12 on sodiumglucose transporter 2 inhibitors (SGLT-2i), and 2 on dipeptidyl-peptidase 4 inhibitors (DPP4i). The mean age was 65.3 years (43-83). Study participants were mainly men (73%). The body weight (BW) ranged from 56 to 145 kg, and the waist circumference ranged from 88 to 146 cm. The mean HbA1c was 51.0 mmol/mol. At T2, no statistically significant changes were observed from baseline except for BW [-1.6 (-2.60 to -0.62)] and HbA1c [-2.90 (-4.69; -1.12)]. Conclusion: We evaluated the effects of the COVID-19 lockdown on glucometabolic control in patients with background well-controlled T2D. We found that the lockdown had no adverse effects on metabolic profile regardless of background clinical characteristics and antihyperglycemic management. Despite limitations due to the nature of this study (sample size, retrospective observation, lack of data on lifestyle changes in our patients' everyday lives), T2D patients managed in our Diabetes Centers faced the lockdown-related restrictions without any detrimental consequence.

Omega-6 and omega-3 oxylipins may be surrogate markers of systemic inflammation, which is one of the triggers for the development of cardiometabolic disorders. In the current study, we investigated the relationship between plasma levels of omega-6 and omega-3 oxylipins with body composition and cardiometabolic risk factors in middle-aged adults. Seventy-two 72 middle-aged adults (39 women; 53.6±5.1 years old; 26.7±3.8 kg/m2) were included in this cross-sectional study. Plasma levels of omega-6 and omega-3 fatty acids and oxylipins were determined using targeted lipidomic. Body composition, dietary intake, and cardiometabolic risk factors were assessed with standard methods. The plasma levels of the omega-6 fatty acids and derived oxylipins, the hydroxyeicosatetraenoic acids (HETEs; arachidonic acid (AA)-derived oxylipins) and dihydroxy-eicosatrienoic acids (DiHETrEs; AA-derived oxylipins), were positively associated with glucose metabolism parameters (i.e., insulin levels and homeostatic model assessment of insulin resistance index (HOMA); all r≥0.21, P

Abstract: Tirzepatide (mounjaro®) is a derivative of the human glucose-dependent insulinotropic polypeptide (GIP) hormone with a position-20 being modified with 1,20- eicosanedioic acid via a chemical linker. It acts as a glucagon-like peptide-1 (GLP-1) receptor and GIP receptor agonist. It has recently been approved by FDA as an adjunct therapy to exercise and diet to improve glycemic control in patients with type II diabetes mellitus (T2DM). It represents a new transforming paradigm in the management of T2DM. This mini-review will shed light on its different pharmacokinetic and pharmacodynamic aspects.

Objective: Individuals with 45,X/46,XY or 46,XY gonadal dysgenesis are at increased risk of germ cell malignancies. Therefore, prophylactic bilateral gonadectomy is advised in girls and considered in boys with atypical genitalia for undescended, macroscopically abnormal gonads. However, severely dysgenetic gonads may not contain germ cells rendering gonadectomy unnecessary. Therefore, we investigate if undetectable preoperative serum anti-Müllerian hormone (AMH) and inhibin B can predict the absence of germ cells, (pre)malignant or otherwise. Design, Patients and Measurements: Individuals who had undergone bilateral gonadal biopsy and/or gonadectomy because of suspected gonadal dysgenesis in 1999–2019 were included in this retrospective study if preoperative AMH and/or inhibin B were available. Histological material was reviewed by an experienced pathologist. Haematoxylin and eosin and immunohistochemical stainings for SOX9, OCT4, TSPY and SCF (KITL) were used. Results: Thirteen males and 16 females were included, 20 with 46,XY and 9 with 45,X/46,XY DSD. Three females had dysgerminoma alongside gonadoblastoma; two gonadoblastoma, one germ cell neoplasia in situ (GCNIS) and three males had pre-GCNIS and/or pre-gonadoblastoma. Gonadoblastoma and/or dysgerminoma were present in 3/11 individuals with undetectable AMH and inhibin B, one of whom also had non-(pre)malignant germ cells. Of the other 18, in whom AMH and/or inhibin B were detectable, only one had no germ cells. Conclusions: Undetectable serum AMH and inhibin B cannot reliably predict the absence of germ cells and germ cell tumours in individuals with 45,X/46,XY or 46,XY gonadal dysgenesis. This information should help in counselling about prophylactic gonadectomy, taking into account both the germ cell cancer risk and potential for gonadal function.

Background: Allergic asthma is a chronic inflammatory illness of the respiratory system characterized by an increase in the number of inflammatory cells in the airways and trouble breathing. Mesenchymal stem cells (MSCs) have the potential to be used in inflammatory diseases as a cellular immunosuppressive treatment. They express calcitriol receptors and communicate with other immunocytes, which increases their anti-inflammatory activity. This study aimed to determine the effects of calcitriol-treated MSC treatment on allergic asthma pathways in a mouse model. Methods: To generate a mouse model of asthma, the mice were sensitized intraperitoneally with ovalbumin (OVA) and aluminum hydroxide emulsion and then challenged intra-nasally with OVA. On day 14, experimental mice received tail vein injections of calcitriol-treated MSCs in PBS prior to allergen exposure. The cytokines assays including IL-4, 10, 12, 17, TGF-β and IFN-γ, splenocytes proliferation, and histological examination of lungs samples were performed. The mice were sensitized with OVA and the response to dexamethasone treatment was compared. Results: Calcitriol-treated MSCs significantly increased the levels of IL-12, TGF-β, and IFN-γ compared to non-treated MSCs groups. Moreover, calcitriol-treated and non-treated MSCs significantly decreased IL-4 and IL-17 compared to asthmatic groups. The results of the histopathological examination showed that calcitriol-treated MSCs reduced the accumulation of inflammatory cells and bronchial wall thickening in comparison with the asthma group. Conclusion: Using the allergic asthma model, we were able to show that calcitriol-treated MSCs had an inhibitory impact on airway inflammation. Our findings suggest that the injection of calcitrioltreated MSCs may be a viable treatment option for allergic asthma.

Aim: To describe the design of the SOUL trial (Semaglutide cardiOvascular oUtcomes triaL) and the baseline clinical data of its participants. Materials and methods: In SOUL, the effects of oral semaglutide, the first oral glucagon-like peptide-1 receptor agonist, on the risk of cardiovascular (CV) events in individuals with type 2 diabetes and established atherosclerotic CV disease (ASCVD) and/or chronic kidney disease (CKD) will be assessed. SOUL is a randomized, double-blind, parallel-group, placebo-controlled CV outcomes trial comparing oral semaglutide (14 mg once daily) with placebo, both in addition to standard of care, in individuals aged ≥50 years with type 2 diabetes and evidence of ASCVD (coronary artery disease [CAD], cerebrovascular disease, symptomatic peripheral arterial disease [PAD]) and/or CKD (estimated glomerular filtration rate

Aim: The study aims to show that sodium selenite (Ss) would have an immunomodulatory effect on the functional activity of proinflammatory macrophages (Mφs) during their extended extracellular activation at the onset of human type 1 diabetes (T1D). Background: Exacerbated activation of proinflammatory “M1” macrophages (Mϕs) can promote chronic local pancreatic islet inflammation and T1D development. Objective: We investigated the ex vivo effects of Ss on the immune modulation of global/extended activation of human proinflammatory M1-like Mϕs. Methods: Experiments were carried out on primary monocytes-derived Mϕs (MDMs). Results: The levels of IL-1β, TNF-α, H2O2 and intracellular free calcium ions (ifCa2+), and the ratios of IL-1β-to-IL-10 and TNF-α-to-IL-10 were markedly increased in T1D Mϕs than in healthy control Mϕs. Conversely, both IL-10 production and arginase 1 (ARG1) activity were downregulated in T1D Mϕs. Additionally, Ss treatment induced a marked downregulation of respiratory burst, ifCa2+ levels, M1-like Mϕ-associated inducible nitric oxide (NO) synthase (iNOS) activity, cell necrosis and related necroinflammation biomarkers, including IL-1β and TNF-α, CD14 expression, and the ratios of iNOS-to-ARG1, IL-1β-to-IL-10, and TNF-α-to-IL-10. Moreover, Ss upregulated anti-inflammatory “M2-like” Mϕ activity as demonstrated by ARG1 activity and IL-10 production, as well as phagocytosis capacity. Conclusions: Ss exerts a potent immunomodulatory role on functional activities of human proinflammatory T1D M1-like Mϕs subjected to extended activation, as well as on the M1-like/M2-like dichotomy. Additionally, the current study provides a novel therapeutic approach using Ss to promote the anti-inflammatory function of Mϕs at the onset of T1D.
