Effects of Intensive Blood Glucose Control on Surgical Site Infection for Liver Transplant Recipients: A Randomized Controlled Trial. Transplant Proc 2023; 55:170-177. [PMID: 36567173 DOI: 10.1016/j.transproceed.2022.10.062] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Revised: 09/07/2022] [Accepted: 10/18/2022] [Indexed: 12/25/2022]
Abstract
BACKGROUND The evidence supporting intensive blood glucose control to prevent surgical site infections (SSIs) among liver transplant recipients is insufficient. We aimed to assess the effects of postoperative intensive blood glucose control (IBGC) against standard blood glucose control (SBGC) on the incidence of SSIs among adult liver transplant recipients. METHODS We performed a randomized controlled trial (ClinicalTrials.gov identifier NCT03474666). The IBGC target was 80 to 130 mg/dL, and the SBGC target was below 180 mg/dL. Analyses were made on an intention-to-treat basis. RESULTS Of the 41 recipients enrolled onto the trial, 20 were randomly allocated to the IBGC group and 21 to the SBGC group. There were no significant differences in SSIs among recipients allocated to either group (relative risk [RR], 0.78; 95% confidence interval [CI], 0.21-2.88; P = .69). Mean (SD) blood glucose levels were significantly lower in the IBGC group in the 24-hour period after surgery (145.0 [20.7] mg/dL and 230.2 [51.6] mg/dL; P = .001). While there were fewer episodes of hypoglycemia in the IBGC group, this was not statistically significant. There were no episodes of severe hypoglycemia in either group. Hyperglycemia and severe hyperglycemia were significantly more frequent in the SBGC group (RR, 0.70; 95% CI, 0.52-0.93; P = .001 and RR, 0.07; 95% CI, 0.01-0.48; P = .001, respectively). Length of hospital stay was significantly shorter for recipients in the IBGC group (13.1 [5.5] days vs 19.3 [12.1] days; P = .04). CONCLUSIONS Although this small trial did not find intensive control reduced SSI, it was associated with lower blood glucose levels, fewer episodes of hyperglycemia and severe hyperglycemia, and shorter length of hospital stay.

Abstract
Systemic inflammatory response syndrome (SIRS) is a life-threatening condition with nonspecific symptoms. Because of that, defining a targeted therapy against SIRS in children and adults remains a challenge. The identification of diagnostic patterns from individualized immuneprofiling can lead to development of a personalized therapy. The aim of this study was to identify and analyze ethical issues associated with personalized research and therapy for SIRS in pediatric populations. We conducted an ethical analysis based on a principled approach according to Beauchamp and Childress' four bioethical principles. Relevant information for the research objectives was extracted from a systematic literature review conducted in the scientific databases PubMed, Embase and Web of Science. We searched for pertinent themes dealing with at least one of the four bioethical principles: "autonomy", "non-maleficence", "beneficence" and "justice". 48 publications that met the research objectives were included in the thorough analysis, structured and discussed in a narrative synthesis. From the analysis of the results, it has emerged that traditional paradigms of patient's autonomy and physician paternalism need to be reexamined in pediatric research. Standard information procedures and models of informed consent should be reconsidered as they do not accommodate the complexities of pediatric omics research.

[PMID: 34332547 PMCID: PMC8325420 DOI: 10.1186/s12874-021-01344-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Accepted: 07/08/2021] [Indexed: 11/25/2022] Open
Abstract
BACKGROUND Data monitoring of clinical trials is a tool aimed at reducing the risks of random errors (e.g. clerical errors) and systematic errors, which include misinterpretation, misunderstandings, and fabrication. Traditional 'good clinical practice data monitoring' with on-site monitors increases trial costs and is time consuming for the local investigators. This paper aims to outline our approach of time-effective central data monitoring for the SafeBoosC-III multicentre randomised clinical trial and present the results from the first three central data monitoring meetings. METHODS The present approach to central data monitoring was implemented for the SafeBoosC-III trial, a large, pragmatic, multicentre, randomised clinical trial evaluating the benefits and harms of treatment based on cerebral oxygenation monitoring in preterm infants during the first days of life versus monitoring and treatment as usual. We aimed to optimise completeness and quality and to minimise deviations, thereby limiting random and systematic errors. We designed an automated report which was blinded to group allocation, to ease the work of data monitoring. The central data monitoring group first reviewed the data using summary plots only, and thereafter included the results of the multivariate Mahalanobis distance of each centre from the common mean. The decisions of the group were manually added to the reports for dissemination, information, correcting errors, preventing furture errors and documentation. RESULTS The first three central monitoring meetings identified 156 entries of interest, decided upon contacting the local investigators for 146 of these, which resulted in correction of 53 entries. Multiple systematic errors and protocol violations were identified, one of these included 103/818 randomised participants. Accordingly, the electronic participant record form (ePRF) was improved to reduce ambiguity. DISCUSSION We present a methodology for central data monitoring to optimise quality control and quality development. The initial results included identification of random errors in data entries leading to correction of the ePRF, systematic protocol violations, and potential protocol adherence issues. Central data monitoring may optimise concurrent data completeness and may help timely detection of data deviations due to misunderstandings or fabricated data.

Abstract
OBJECTIVES This article will provide an overview of the purpose, structure, and function of an investigational pharmacy in oncology clinical research. It will also discuss the role of the oncology nurse in managing investigational drugs (ID) when caring for a patient receiving treatment on a clinical trial and the importance of their role in the trial process. DATA SOURCES Government regulations, professional guidelines, and best practices. CONCLUSION ID management for clinical trials is a multidisciplinary process requiring input from various professionals to ensure safe, accurate, and study-specific administration. The nurse's role in the process of clinical trial ID management is dependent on each institution's expectations of clinical research nurses and the scope of their role. IMPLICATIONS FOR NURSING PRACTICE Multiple nursing roles may be involved in caring for patients who are being treated as part of a clinical trial, including clinical research nurses, infusion nurses, or as nurses providing direct patient care (inpatient or outpatient). Providing education on ID management, specific to the nurse's involvement, is a responsibility of the study team. Ensuring proper safeguards, accurate and protocol-specific delivery and documentation of ID, and completion of patient education are key in the conduct of oncology clinical research.

Abstract
When a clinical trial has a composite endpoint and a comparison of treatment strategies with multiple intervention components, interim data reviews by a data safety and monitoring board (DSMB) can be challenging as the data evolve on multiple fronts. We illustrate with a study in the treatment of Kaposi sarcoma (KS), an HIV-associated cancer with a multi-faceted disease presentation. The study, ACTG-A5264/AMC-067, was a 1:1 randomized trial to compare two strategies: immediate initiation of etoposide with antiretroviral therapy (ART), or ART with delayed etoposide upon disease progression. The outcome was a composite endpoint that included the following events, ordered from worst to best in the following three categories: (1) KS progression at 48 weeks, death, initiation of alternate KS treatment, loss to study follow-up; (2) stable KS; and (3) partial or complete KS response at 48 weeks. We present the interim results on the composite endpoint and the individual components, where components favored different study arms at an interim review. To facilitate interim data monitoring for complex trials, we recommend clear communications between the study team and the DSMB prior to the initiation of the trial on the need for a composite endpoint, the intentions behind the defined strategies, and relative importance of individual components of the composite endpoint. We also recommend flexibility in the timing of data reviews by the DSMB to interpret emerging data in multiple dimensions. Clinicaltrials.govNCT01352117.

Abstract
Several promising therapies assessed in the adult critically ill in large, multicenter randomized controlled trials (RCTs) were associated with significantly increased mortality in the intervention arms. Our hypothesis was that there would be wide ranges in sponsorship (industry or not), type(s) of intervention(s), use of DSMBs, presence of interim analyses and early stopping rules, absolute risk increase (ARI), and whether or not adequate prior proof-of-principle Phase II studies were done of RCTs that found increased mortality rates of the intervention compared to control groups. We reviewed RCTs that showed a statistically significant increased mortality rate in the intervention compared to control group(s). We recorded source of sponsorship, sample sizes, types of interventions, mortality rates, ARI (as well as odds ratios, relative risks and number needed to harm), whether there were pre-specified interim analyses and early stopping rules, and whether or not there were prior proof-of-principle (also known as Phase II) RCTs. Ten RCTs (four industry sponsored) of many interventions (high oxygen delivery, diaspirin cross-linked hemoglobin, growth hormone, methylprednisolone, hetastarch, high-frequency oscillation ventilation, intensive insulin, NOS inhibition, and beta-2 adrenergic agonist, TNF-α receptor) included 19,126 patients and were associated with wide ranges of intervention versus control group mortality rates (25.7–59 %, mean 29.9 vs 17–49 %, mean 25 %, respectively) yielding ARIs of 2.6–29 % (mean 5 %). All but two RCTs had pre-specified interim analyses, and seven RCTs were stopped early. All RCTs were preceded by published proof-of-principle RCT(s), two by the same group. Seven interventions (except diaspirin cross-linked hemoglobin and the NOS inhibitor) were available for use clinically at the time of the pivotal RCT. Common, clinically available interventions used in the critically ill were associated with increased mortality in large, pivotal RCTs even though safety was often addressed by interim analyses and early stopping rules.

Clyburne-Sherin AVP, Thurairajah P, Kapadia MZ, Sampson M, Chan WWY, Offringa M. Recommendations and evidence for reporting items in pediatric clinical trial protocols and reports: two systematic reviews. Trials 2015; 16:417. [PMID: 26385379 PMCID: PMC4574457 DOI: 10.1186/s13063-015-0954-0] [Citation(s) in RCA: 25] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2015] [Accepted: 09/11/2015] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Complete and transparent reporting of clinical trial protocols and reports ensures that these documents are useful to all stakeholders, that bias is minimized, and that the research is not wasted. However, current studies repeatedly conclude that pediatric trial protocols and reports are not appropriately reported. Guidelines like SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) and CONSORT (Consolidated Standards of Reporting Trials) may improve reporting, but do not offer guidance on issues unique to pediatric trials. This paper reports two systematic reviews conducted to build the evidence base for the development of pediatric reporting guideline extensions: 1) SPIRIT-Children (SPIRIT-C) for pediatric trial protocols, and 2) CONSORT-Children (CONSORT-C) for pediatric trial reports. METHOD MEDLINE, the Cochrane Methodology Register, and reference lists of included studies were searched. Publications of any type were eligible if they included explicit recommendations or empirical evidence for the reporting of potential items in a pediatric protocol (SPIRIT-C systematic review) or trial report (CONSORT-C systematic review). Study characteristics, recommendations and evidence for pediatric extension items were extracted. Recurrent themes in the recommendations and evidence were identified and synthesized. All steps were conducted by two reviewers. RESULTS For the SPIRIT-C and CONSORT-C systematic reviews 366 and 429 publications were included, respectively. Recommendations were identified for 48 of 50 original reporting items and sub-items from SPIRIT, 15 of 20 potential SPIRIT-C reporting items, all 37 original CONSORT items and sub-items, and 16 of 22 potential CONSORT-C reporting items. The following overarching themes of evidence to support or refute the utility of reporting items were identified: transparency; reproducibility; interpretability; usefulness; internal validity; external validity; reporting bias; publication bias; accountability; scientific soundness; and research ethics. CONCLUSION These systematic reviews are the first to systematically gather evidence and recommendations for the reporting of specific items in pediatric protocols and trials. They provide useful and translatable evidence on which to build pediatric extensions to the SPIRIT and CONSORT reporting guidelines. The resulting SPIRIT-C and CONSORT-C will provide guidance to the authors of pediatric protocols and reports, respectively, helping to alleviate concerns of inappropriate and inconsistent reporting, and reduce research waste.
