Exploration of registration and the risk of bias in acupuncture randomised controlled trials: a systematic review protocol.

BACKGROUND: Randomised controlled trials (RCTs) are the predominant type in acupuncture clinical research, and the publications have increased rapidly in recent years, but there is a prevalence of the high risk of bias and poor methodological design in acupuncture RCTs. Clinical trial registration can improve the transparency and credibility of studies by disclosing key information in advance. However, the registration in acupuncture RCTs is not satisfactory, as there is widespread of the under-registration, inconsistency with published studies and insufficient disclosure of key methodological information. Whether registration can reduce the risk of bias in acupuncture RCTs and improve data transparency has not been fully explored. Therefore, we constructed this study to investigate the association between registration and risk of bias and data sharing level in acupuncture RCTs. METHODS: Seven databases including MEDLINE, EMBASE, CENTRAL, CBM, CNKI, Wanfang and VIP databases will be systematically searched between 1 January 2014 and 31 March 2024, for acupuncture RCTs. Two reviewers will independently extract data using a predefined standardised format and perform secondary validation. The characteristics and data sharing level of the included studies will be summarised. The risk of bias of included RCTs will be assessed by the revised Cochrane risk-of-bias tool for randomised trials. The risk of bias and registration in acupuncture RCTs will be analysed by logistic or quantile regression analyses (depending on the number of minimum events). The data sharing level and registration will be analysed by quantile regression analyses. ETHICS AND DISSEMINATION: As the systematic review aims to consolidate info from published sources, ethical approval is not necessary for this study. The study's findings will be submitted to a peer-reviewed academic journal and disseminated via conference presentations. This protocol has been registered in Open Science Framework Registries.

Reporting and influencing factors of patient-reported outcomes in acupuncture randomised controlled trials: a cross-sectional study protocol.

INTRODUCTION: Patient-reported outcomes (PROs) are health reports that come directly from the patients themselves and represented the experience and insights of the patient's perspective on the impact of the intervention. PROs were increasingly emphasised in acupuncture randomised controlled trials (RCTs). However, the reporting quality of PROs in acupuncture RCTs has not been investigated to date. Therefore, we constructed this study to reveal the basic characteristics and reporting quality of PROs in acupuncture RCTs, and explore the relationship between concealment, blinding and RROs. We hope our findings can provide guidance for the reporting standards and future development of PROs in acupuncture RCTs in reverse. METHODS AND ANALYSIS: RCTs using acupuncture treatment as the intervention and PROs as primary outcomes or secondary outcomes will be systematically searched through seven databases MEDLINE, EMBASE, CENTRAL, CBM, CNKI, Wanfang and VIP between 1 January 2012 and 15 October 2022. The basic characteristics, concealment, blinding design and the characteristics of PROs in included RCTs will be summarised. The reporting quality of PROs will be assessed based on the CONSORT PRO extension. Logistic analysis will be performed to identify the association between concealment, blinding and RROs. ETHICS AND DISSEMINATION: Ethical approval is not required for this study. This protocol has been registered in Open Science Framework (OSF) Registries. The findings of this study will be submitted to a peer-reviewed academic journal.

Repeated use of SSRIs potentially associated with an increase on serum CK and CK-MB in patients with major depressive disorder: a retrospective study.

There is a large amount of evidence that selective serotonin reuptake inhibitors (SSRIs) are related to cardiovascular toxicity, which has aroused concern regarding their safety. However, few studies have evaluated the effects of SSRIs on cardiac injury biomarkers, such as creatine kinase (CK) and creatine kinase isoenzyme (CK-MB). The purpose of our study was to determine whether SSRIs elevated CK and CK-MB levels of prior medicated depressive patients (PMDP) compared to first-episode drug-naïve depressive patients (FDDPs). We performed an observational and retrospective study involving 128 patients with major depressive disorder. Patients who had never used any type of antidepressant were designated FDDP; patients who had used only one type of SSRI but were not treated after a recent relapse were designated PMDP. Serum CK and CK-MB levels were measured before and after using SSRIs for a period of time. The duration of current treatment in the FDDP and PMDP groups was 16.200 ± 16.726 weeks and 15.618 ± 16.902 weeks, respectively. After SSRI treatment, levels of serum CK in the PMDP group were significantly higher than in the FDDP group. Univariate ANCOVA results revealed that PMDP was 22.313 times more likely to elevate CK (OR 22.313, 95% CI 9.605-35.022) and 2.615 times more likely to elevate CK-MB (OR 2.615, 95% CI 1.287-3.943) than FDDP. Multivariate ANCOVA revealed an interaction between the group and sex of CK and CK-MB. Further pairwise analysis of the interaction results showed that in female patients, the mean difference (MD) of CK and CK-MB in PMDP was significantly greater than that in FDDP (MD = 33.410, P = 0.000, 95% CI 15.935-50.886; MD = 4.613, P = 0.000, 95% CI 2.846-6.381). Our findings suggest that patients, especially females, who had previously used SSRI antidepressants were more likely to have elevated CK and CK-MB, indicators of myocardial muscle injury. Use of SSRIs should not be assumed to be completely safe and without any cardiovascular risks.

Pharmacokinetics of guaifenesin, pseudoephedrine and hydrocodone in a combination oral liquid formulation, administered as single and multiple doses in healthy Chinese volunteers, and comparison with data for individual compounds formulated as Antuss®.

1. A new oral liquid formulation combining guaifenesin, pseudoephedrine and hydrocodone is effective in improving the symptoms of common cold. The pharmacokinetic properties of the individual components were evaluated in a randomized, open-label, four-period study in 12 healthy Chinese volunteers following single and multiple doses. The data were compared with data for the individual ingredients in Antuss®. 2. In the single-dose period, exposure levels (AUC and Cmax) for guaifenesin, pseudoephedrine and hydrocodone increased directly as the dose of the oral liquid formulation increased from 5 to 15 mL. Only minor amounts of guaifenesin and hydrocodone were excreted in urine (∼0.10% and 4.66%, respectively). Pseudoephedrine was mainly excreted unchanged, with 44.95% of the dose excreted in urine within 24 h. After multiple dosing, there was no obvious accumulation of any drug, as assessed by AUC. When considering Cmax, there was a trend toward accumulation of hydrocodone and pseudoephedrine. The pharmacokinetic profiles of guaifenesin and pseudoephedrine in the oral liquid formulation were similar to those in the branded preparation, Antuss®. 3. The newly developed oral liquid formulation combining guaifenesin, pseudoephedrine and hydrocodone was safe and well tolerated and might provide a reliable alternative to the branded formulation for patients with common colds.

Pharmacokinetic Properties of Peramivir After Single and Multiple Intravenous Infusions in Healthy Chinese Volunteers.

BACKGROUND AND OBJECTIVES: Peramivir, an antiviral agent for intravenous administration, is used to treat progressive influenza in patients with serious complications. The present study was designed to determine the pharmacokinetics of single and multiple intravenous infusions of peramivir in healthy Chinese subjects. METHODS: Single (150, 300 and 600 mg) and multiple (600 mg) doses of peramivir were intravenously administered to 12 healthy Chinese subjects. There was a 7-day washout period between dosing periods. Blood samples were collected in heparinized tubes at various times. Plasma peramivir and urine peramivir concentrations were measured using a high-performance liquid chromatography-tandem mass spectrometry method. RESULTS: Following single doses of peramivir (150, 300 and 600 mg), the maximum concentration (C max) values were 12,416 ± 3078, 23,147 ± 3668 and 44,113 ± 3787 µg/L, respectively, and the area under the plasma concentration-time curve (AUC) from 0 h to infinity post-dose (AUC∞) values were 24.68 ± 6.48, 47.33 ± 9.22 and 92.43 ± 12.72 mg·h/L, respectively. C max, AUC from 0 to 36 h (AUC0-36) and AUC∞ of peramivir increased proportionally with the dose, and no trend towards accumulation after multiple doses was observed. About 65 % of the peramivir was excreted unchanged in the urine within the first 24 h. CONCLUSIONS: Peramivir pharmacokinetics were dose proportional with increasing doses, with no accumulation after multiple dosing. Peramivir was generally well tolerated, and no serious adverse events occurred.
