Article Abstract
Background And Objective: Quadpill, a single pill containing a quadruple combination of quarter doses of four antihypertensive agents, has been investigated for hypertension treatment. This meta-analysis aims to evaluate the safety and efficacy of quadpill for hypertension management.
Methods: We conducted a systematic review and meta-analysis synthesizing randomized controlled trials evaluating quadpill versus monotherapy or placebo in patients with hypertension, which were retrieved by systematically searching PubMed, EMBASE, Web of Science, SCOPUS, and Cochrane through 17 February, 2023. Continuous and dichotomous outcomes were pooled using mean difference (MD) and risk ratio (RR) along with confidence interval (CI), using Revman Version 5.4 software. Our protocol has been published in PROSPERO with ID: CRD42023406527.
Results: Four randomized controlled trials with a total of 779 patients were included in our analysis. Quadpill was effective in controlling systolic blood pressure in the short term [4-6 weeks] (RR: - 13.00 with 95% CI [- 17.22, - 8.78], p = 0.00001) and in the long term [12 weeks] (RR: - 6.18 with 95% CI [- 9.35, - 3.01], p = 0.0001). Quadpill was also effective in controlling automated diastolic blood pressure in the short term [4-6 weeks] (MD: - 8.15 with 95% CI [- 9.42, - 6.89], p = 0.00001) and in the long term [12 weeks] (MD: - 6.35 with 95% CI [- 10.37, - 2.33], p = 0.002). Moreover, patients in the quadpill group significantly achieved target blood pressure <140/90 (RR: 1.77 with 95% CI [1.26, 2.51], p = 0.001) compared with the control group.
Conclusions: The quadruple ultra-low-dose combination of antihypertensive drugs (quadpill) was effective and safe for hypertension treatment. However, further large-scale, multicenter, randomized controlled trials are still warranted before endorsement in clinical practice.

Introduction: Risperidone is approved for behaviors and psychological symptoms of dementia (BPSD), despite modest efficacy and known risks. Identifying responsive symptoms, treatment modifiers, and predictors is crucial for personalized treatment.
Method: A one-stage individual participant data meta-analysis of six randomized controlled trials (risperidone: n = 1009; placebo: N = 712) was conducted.

Background: In hyponatremic patients, concurrent dialysate flow during hemodialysis may be an ideal option to mitigate complications such as osmotic demyelination syndrome (ODS).
Methods: Present randomized controlled trial enrolled dialysis-requiring chronic kidney disease (CKD) and acute kidney injury (AKI) patients with serum sodium levels < 125 mEq/L during January 2020 over 16 months. Hemodynamically unstable patients, as well as those with a history of seizures and neurological conditions, were excluded.
Tirzepatide for the Maintenance of Body Weight Reduction: Rationale, Design, and Baseline Characteristics of SURMOUNT-MAINTAIN.

Objective: SURMOUNT-MAINTAIN aims to evaluate the efficacy and safety of reducing the tirzepatide dose and/or continuing the maximum tolerated dose (MTD) versus placebo in maintaining body weight (BW) reduction achieved with tirzepatide MTD.
Methods: This Phase 3b, multicenter, randomized, parallel-arm, double-blinded, placebo-controlled, 52-week clinical trial is in progress comparing treatment with once weekly tirzepatide (5 mg and/or MTD of 15 mg or 10 mg) versus placebo in achieving BW reduction maintenance from the initial 60-week open-label weight-loss period on tirzepatide MTD, in adults with obesity (BMI ≥ 30 kg/m or ≥ 27 kg/m with ≥ 1 obesity-related comorbidity, excluding type 2 diabetes). The primary endpoint is percent maintenance of BW reduction achieved during the weight-loss period at Week 112 among those who reached a BW plateau (i.

The increasing prevalence of overweight/obesity among the elderly has significant implications for oral health due to shared pathophysiological mechanisms. Despite its importance, comprehensive reviews on this topic remain limited. This study investigates the association between overweight/obesity and oral health outcomes in adults aged 55 and older.
