Clinical Features, Cardiovascular Risk Profile, and Therapeutic Trajectories of Patients with Type 2 Diabetes Candidate for Oral Semaglutide Therapy in the Italian Specialist Care

Introduction: This study aimed to address therapeutic inertia in the management of type 2 diabetes (T2D) by investigating the potential of early treatment with oral semaglutide. Methods: A cross-sectional survey was conducted between October 2021 and April 2022 among specialists treating individuals with T2D. A scientific committee designed a data collection form covering demographics, cardiovascular risk, glucose control metrics, ongoing therapies, and physician judgments on treatment appropriateness. Participants completed anonymous patient questionnaires reflecting routine clinical encounters. The preferred therapeutic regimen for each patient was also identified. Results: The analysis was conducted on 4449 patients initiating oral semaglutide. The population had a relatively short disease duration (42%  60% of patients, and more often than sitagliptin or empagliflozin. Conclusion: The study supports the potential of early implementation of oral semaglutide as a strategy to overcome therapeutic inertia and enhance T2D management

Honest vs Cheating Bots in PATROL-Based Real-Time Strategy MMOGs

Massively multiplayer online games (MMOGs) are being increasingly successful, since they allow players to explore huge virtual worlds and to interact in many different ways, either cooperating or competing. To support the implementation of ultra-scalable real-time strategy MMOGs, we are developing a middleware, called PATROL, that is based on a structured peer-to-peer overlay scheme. Among other features, PATROL provides AI-based modules to detect cheating attempts, that the decentralized communication infrastructure may favor. In this work we illustrate how we implemented honest and cheating autonomous players (bots). In particular, we show how honest bots can detect cheating bots in real-time, using strategies based on neural networks

Efficacy and safety of very low calorie ketogenic diet (VLCKD) in patients with overweight and obesity: A systematic review and meta-analysis

Very low calorie ketogenic diet (VLCKD) has been proposed as a promising option to achieve a significant weight loss in a short time period. We conducted a systematic review and meta-analysis to evaluate its efficacy and safety in patients with overweight and obesity. Four databases were searched on May 2019. Studies reporting data on body weight, body mass index (BMI), waist circumference, body composition, blood pressure, HbA1c, lipids, and markers of liver and kidney function were selected. Discontinuation was also assessed. Twelve studies were included. VLCKD was associated with weight losses of -10.0 kg (I2 = 6%) and - 15.6 kg (I2 = 37%) in studies with a ketogenic phase up to and of at least four weeks, respectively. The weight lost during the ketogenic phase was stable in the subsequent follow-up up to two years (p = 0.12). Also, VLCKD was associated with reductions of BMI (-5.3 kg/m2), waist circumference (-12.6 cm), HbA1c (-0.7%), total cholesterol (-28 mg/dl), triglycerides (-30 mg/dl), AST (-7 U/l), ALT (-8 U/l), GGT (-8 U/l), systolic and diastolic blood pressure (-8 and - 7 mmHg, respectively). No changes in LDL cholesterol, HDL cholesterol, serum creatinine, serum uric acid and serum potassium were found. Serum sodium increased during VLCKD (+1.6 mEq/l). The overall prevalence of patients discontinuing VLCKD was 7.5% and this was similar to patients undergoing a low calorie diet (p = 0.83). The present review supports the use of VLCKD as an effective strategy for the management of overweight and obesity. Future guidelines should include a specific recommendation for this intervention

Clinical spectrum of accidental hemlock poisoning: neurotoxic manifestations, rhabdomyolysis and acute tubular necrosis

In the past, hemlock poisoning was only known for its neurotoxic effects; quite recently non-neurological features, consisting of rhabdomyolysis and acute renal failure, have been also described. Here we report our experience with these clinical findings, which we frequently observe in accidental hemlock poisoning. Between 1972 and 1990 we studied 18 patients: 17 of them were poisoned by conline (an alkaloid of Conium maculatim) in Apulia (Italy), and one by cicutoxin (the active principle of water hemlock) in New Mexico (USA). In the non-rapidly-fatal cases we tested myoglobinuria, serum muscle enzymes, and renal function. In the patients with acute renal failure we performed microscopical examination of kidney specimens; immunohistochemistry was carried out to identify myoglobin and actin in tubules. Coniine was detected in urine, serum, or tissues. Neurological features were present in all of our cases: coniine had a curare-like effect on the neuromuscular junction, whereas cicutoxin was convulsant on the central nervous system. In addition rhabdomyolysis was noted in the 17 subjects poisoned by coniine. Acute renal failure was observed in five patients; it was confirmed by histological evidence of tubular necrosis with intratubular deposition of myoglobin and actin released by rhabdomyolysis. Our cases seem to be the first with histopathologically proven acute tubular necrosis in coniine intoxication. In conclusion, in hemlock poisoning neurotoxic manifestations may be accompanied by rhabdomyolysis and acute tubular necrosis; increased awareness of these clinical features is recommended in order to improve the diagnostic and therapeutic procedure
