Four glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have been used in children and adolescents with obesity or overweight. This network meta-analysis was conducted to compare the efficacy and safety of these regimens. Embase, PubMed, and Scopus were searched on March 2023 and updated in June 2024 for eligible randomized controlled trials (RCTs). The primary efficacy outcomes were mean difference in actual body weight, BMI (body mass index), BMI z score, and waist circumference. Safety outcomes included nausea, vomiting, diarrhea, abdominal pain, injection-site reaction, and hypoglycemia. Eleven RCTs with 953 participants were eligible. Semaglutide exhibited greater effects in reducing weight, BMI, and BMI z score versus the placebo. Semaglutide was associated with greater weight loss and BMI z score reduction in comparison with exenatide, liraglutide, and dulaglutide. Semaglutide also significantly decreased BMI than exenatide. None of the four GLP-1 RAs were associated with higher risks of diarrhea, headache, and abdominal pain versus the placebo. Liraglutide was more likely to cause nausea, vomiting, hypoglycemia, and injection-site reactions than the placebo. Liraglutide also had higher odds of causing injection-site reactions than other GLP-1 RAs. Semaglutide appeared to be the most effective and safe option among four GLP-1 RAs in children and adolescents with obesity or overweight.

Background: This study aims to evaluate the efficacy and safety of vonoprazan‐amoxicillin (VA), vonoprazan‐amoxicillin‐clarithromycin (VAC), vonoprazan‐based bismuth‐containing quadruple therapy (VBQT), and PPI‐based triple (PAC) or quadruple therapy (PBQT) for H. pylori infection with the consideration of duration of therapy and amoxicillin dose (H: high; L: low).Materials and Methods: PubMed, Embase, and the Cochrane Central Register of Controlled Trials were searched for eligible randomized controlled trials (RCTs) up to December 15, 2023. The efficacy outcome was eradication rate, and safety outcomes included the rates of adverse events and treatment discontinuation.Results: Twenty‐seven RCTs were included. The pooled eradication rates were 82.8% for VA, 89.1% for VAC, and 91.8% for VBQT, which increased with the higher amoxicillin frequency of administration and extended duration of therapy within each regimen. There were no significant differences in eradication rate when comparing 7‐VA versus 7‐VAC and 14‐VA versus 14‐VAC. VA was at least comparable to PAC. The eradication rate did not differ significantly between 10‐H‐VA or 14‐H‐VA versus 14‐PBQT. 7‐L‐VAC demonstrated higher eradication rate versus 7‐PAC and comparable rate to 14‐PAC. 14‐VBQT showed higher eradication rates versus 14‐PBQT. The adverse events rate was 19.3% for VA, 30.6% for VAC, and 38.4% for VBQT. VA had similar risk of adverse events versus VAC and significantly fewer adverse events compared to PBQT. The treatment discontinuation rate did not differ significantly between treatments.Conclusions: The eradication rate of VBQT was the highest at above 90% followed by VAC and VA. VA was as effective as VAC and superior to PPI‐based therapies with favorable safety, highlighting the potential of VA therapy as a promising alternative to traditional PPI‐based therapies. VPZ‐based triple or quadruple therapies was more effective than PPI‐based therapies. Further studies are needed to establish the optimal treatment regimen especially in the western countries.

Dietary supplement use is common among US adults. We aimed to investigate the quantity, duration, adherence, and reasons for supplement use in individuals who take supplements. Data from 2011 to 2018 from the National Health and Nutrition Examination Survey (NHANES) dataset were analyzed. Four cycles of data were combined to estimate these outcomes. Results are presented as overall group and by subgroups. All analyses were weighted to be nationally representative. The Taylor Series Linearization approach was used to generate variance estimates. A total of 12,529 participants were included. Over 70% of these individuals reported taking more than one unit of dietary supplements daily. Notably, approximately 40% had been taking supplements for more than five years and about 67% were highly adherent to at least one supplement. However, only 26.9% of these supplements were taken following a doctor’s recommendation. The primary reasons for dietary supplements intake included improving overall health (37.2%), maintaining health (34.7%), bone health (21.4%), and diet supplementation (20.3%). Our findings indicate that most participants proactively used multiple dietary supplements focused on self-managed health and prevention, with substantial dedication to long-term use and high adherence. Healthcare professionals should play a more active role in guiding such behaviors to optimize the health outcomes of dietary supplement users across the United States.

Background: Obesity and type 2 diabetes (T2D) are major public health concerns. Tirzepatide has shown promise in recent clinical trials. This systematic review and meta-analysis aim to evaluate the efficacy and safety of tirzepatide in adults with obesity or type 2 diabetes, compared to placebo, GLP-1 receptor agonists (GLP-1 RAs), and insulin. Method: PubMed, Embase, and the Cochrane Library were searched on 17 January 2024, focusing on phase II and III randomized controlled trials (RCTs). We included studies involving adults with T2D or obesity, comparing tirzepatide to placebo, GLP-1 RAs, or insulin. The primary outcomes were the proportion of participants achieving ≥5%, ≥10%, and ≥15% weight loss targets. Secondary outcomes included changes in body weight, waist circumference, HbA1c levels, and blood pressure. Safety outcomes focused on adverse event rates. Meta-analyses were performed, and risk of bias was assessed using the Cochrane Risk-of-Bias tool version 2. Results: Fourteen RCTs involving 14,713 patients were included. Tirzepatide significantly increased the proportion of participants achieving weight loss targets, and reduced body weight, waist circumference, HbA1c, and blood pressure versus placebo and insulin. Compared with GLP-1 RAs, tirzepatide provided comparable or better outcomes in weight loss, waist circumference, and glycemic control. The incidence of gastrointestinal adverse events was significantly higher at all doses of tirzepatide compared to placebo and insulin. When compared with GLP-1 RAs, higher doses of tirzepatide were associated with increased risk of nausea, diarrhea, and decreased appetite, but not vomiting. Conclusions: Tirzepatide is an effective option for managing weight and improving metabolic outcomes in patients with T2D or obesity. However, it is associated with an increased risk of gastrointestinal adverse events, especially at higher doses. Therefore, close monitoring should be considered in clinical practice.

The eradication of Helicobacter pylori (H. pylori) infection remains challenging due to increasing bacterial resistance. Resistance rates to clarithromycin, metronidazole, and levofloxacin were higher than 30% in the USA, making current therapies less effective. Vonoprazan triple therapy (VAC) has demonstrated similar efficacy and safety profiles compared to PPI-based triple therapy (PPI). However, the eradication rate of vonoprazan dual therapy (VA) for H. pylori infection in comparison to VAC, and PPI was poorly established. Electronic databases were searched up to 6 October 2022, to identify studies examining the safety and efficacy of VA compared to VAC and PPI. Six studies were included. For empiric therapies among treatment naïve patients, VA, VAC, and PPI did not achieve high cure rates (>90%). The comparative efficacy ranking showed VAC was the most effective therapy, followed by VA, and PPI. The results were similar for clarithromycin-resistant infections. The comparative safety ranking showed VA ranked first, whereas PPI triple therapy was the least safe regimen. These findings should guide the selection of the most effective and safe treatment and conduct additional studies to determine the place of vonoprazan dual versus triple therapies in patients with H. pylori from various countries across the world.
