Objective To compare the benefits and harms of drug treatments for adults with type 2 diabetes, adding non-steroidal mineralocorticoid receptor antagonists (including finerenone) and tirzepatide (a dual glucose dependent insulinotropic polypeptide (GIP)/glucagon-like peptide-1 (GLP-1) receptor agonist) to previously existing treatment options. Design Systematic review and network meta-analysis. Data sources Ovid Medline, Embase, and Cochrane Central up to 14 October 2022. Eligibility criteria for selecting studies Eligible randomised controlled trials compared drugs of interest in adults with type 2 diabetes. Eligible trials had a follow-up of 24 weeks or longer. Trials systematically comparing combinations of more than one drug treatment class with no drug, subgroup analyses of randomised controlled trials, and non-English language studies were deemed ineligible. Certainty of evidence was assessed following the GRADE (grading of recommendations, assessment, development and evaluation) approach. Results The analysis identified 816 trials with 471 038 patients, together evaluating 13 different drug classes; all subsequent estimates refer to the comparison with standard treatments. Sodium glucose cotransporter-2 (SGLT-2) inhibitors (odds ratio 0.88, 95% confidence interval 0.83 to 0.94; high certainty) and GLP-1 receptor agonists (0.88, 0.82 to 0.93; high certainty) reduce all cause death; non-steroidal mineralocorticoid receptor antagonists, so far tested only with finerenone in patients with chronic kidney disease, probably reduce mortality (0.89, 0.79 to 1.00; moderate certainty); other drugs may not. The study confirmed the benefits of SGLT-2 inhibitors and GLP-1 receptor agonists in reducing cardiovascular death, non-fatal myocardial infarction, admission to hospital for heart failure, and end stage kidney disease. Finerenone probably reduces admissions to hospital for heart failure and end stage kidney disease, and possibly cardiovascular death. Only GLP-1 receptor agonists reduce non-fatal stroke; SGLT-2 inhibitors are superior to other drugs in reducing end stage kidney disease. GLP-1 receptor agonists and probably SGLT-2 inhibitors and tirzepatide improve quality of life. Reported harms were largely specific to drug class (eg, genital infections with SGLT-2 inhibitors, severe gastrointestinal adverse events with tirzepatide and GLP-1 receptor agonists, hyperkalaemia leading to admission to hospital with finerenone). Tirzepatide probably results in the largest reduction in body weight (mean difference −8.57 kg; moderate certainty). Basal insulin (mean difference 2.15 kg; moderate certainty) and thiazolidinediones (mean difference 2.81 kg; moderate certainty) probably result in the largest increases in body weight. Absolute benefits of SGLT-2 inhibitors, GLP-1 receptor agonists, and finerenone vary in people with type 2 diabetes, depending on baseline risks for cardiovascular and kidney outcomes ( https://matchit.magicevidence.org/230125dist-diabetes ). Conclusions This network meta-analysis extends knowledge beyond confirming the substantial benefits with the use of SGLT-2 inhibitors and GLP-1 receptor agonists in reducing adverse cardiovascular and kidney outcomes and death by adding information on finerenone and tirzepatide. These findings highlight the need for continuous assessment of scientific progress to introduce cutting edge updates in clinical practice guidelines for people with type 2 diabetes.

The tumour suppressor candidate 3 (TUSC3) gene is located on chromosome region 8p22 and encodes the 34 kD TUSC3 protein, which is a subunit of the oligosaccharyl transferase responsible for the N‐glycosylation of nascent proteins. Known to be related to autosomal recessive mental retardation for several years, TUSC3 has only recently been identified as a potential tumour suppressor gene. Based on the structure and function of TUSC3, specific mechanisms in various diseases have been investigated. Several studies have demonstrated that TUSC3 is an Mg2+‐transporter involved in magnesium transport and homeostasis, which is important for learning and memory, embryonic development and testis maturation. Moreover, dysfunction or deletion of TUSC3 exerts its oncological effects as a modulator by inhibiting glycosylation efficiency and consequently inducing endoplasmic reticulum stress and malignant cell transformation. In this study, we summarize the advances in the studies of TUSC3 and comment on the potential roles of TUSC3 in diagnosis and treatment of TUSC3‐related diseases, especially cancer.
Objective:It is unknown whether the intravascular ultrasound (IVUS) guidance for percutaneous coronary intervention (PCI) should be routinely used in small-vessel coronary lesions in patients affected by Type 2 diabetes mellitus (T2DM). This study aimed to assess the clinical significance of the IVUS-guided PCI treatment for small-vessel coronary lesions in T2DM.Methods:This was a prospective interventional trial. A total of 228 patients affected by T2DM with stable angina and a positive stress test in the presence of coronary arteriography (CAG) involving small vessels [online measurement reference vessel diameter ≤3.0 mm by means of quantitative coronary angiography (QCA)] were recruited and divided into two groups: an IVUS-guided group (n=120) and a CAG-guided group (n=108). Follow-up PCIs were performed via CAG or IVUS criteria, respectively. Between-group comparisons were made for the number of stents implanted, length, diameter, and high-pressure balloons used post-dilatation. Major adverse cardiac events (MACEs) defined as cardiac death, nonfatal myocardial infarction, and target lesion revascularization (TLR) were the primary endpoint. The value of late lumen loss and proportion of in-stent restenosis (ISR) were the secondary endpoint, all of which were also evaluated during the follow-up period.Results:There was an increased lesion length observed using the IVUS measurement when compared with QCA measurements in the IVUS-guided group (p≤0.001). The number of implanted stents, diameter, length, percentage of high-pressure balloons used during post-dilatation, value of late lumen loss, and proportion of ISR decreased in the IVUS-guided group when compared with the CAG-guided group (p=0.002, p=0.001, p=0.003, p=0.004, p=0.007, p=0.001, respectively). After a 2-year follow-up, the Kaplan–Meier curves indicated that the incidence of MACEs was significantly lower in the IVUS-guided group (log-rank p=0.029), mainly because of the TLR reduction (log-rank p=0.037).Conclusion:The IVUS-guided PCI treatment improved the event-free survival in small-vessel coronary lesions in patients affected by T2DM.
