Social determinants of health and disparities in pediatric trauma care: protocol for a systematic review and meta-analysis.

BACKGROUND: Social determinants of health (SDH), including "the conditions in which individuals are born, grow, work, live and age" affect child health and well-being. Several studies have synthesized evidence about the influence of SDH on childhood injury risks and outcomes. However, there is no systematic evidence about the impact of SDH on accessing care and quality of care once a child has suffered an injury. We aim to evaluate the extent to which access to care and quality of care after injury are affected by children and adolescents' SDH. METHODS: Using Cochrane methodology, we will conduct a systematic review including observational and experimental studies evaluating the association between social/material elements contributing to health disparities, using the PROGRESS-Plus framework: place of residence, race/ethnicity/culture/language, occupation, gender/sex, religion, education, socioeconomic status, and social capital and care received by children and adolescents (≤ 19 years of age) after injury. We will consult published literature using PubMed, EMBASE, CINAHL, PsycINFO, Web of Science, and Academic Search Premier and grey literature using Google Scholar from their inception to a maximum of 6 months prior to submission for publication. Two reviewers will independently perform study selection, data extraction, and risk of bias assessment for included studies. The risk of bias will be assessed using the ROBINS-E and ROB-2 tools respectively for observational and experimental study designs. We will analyze data to perform narrative syntheses, and if enough studies are identified, we will conduct a meta-analysis using random effects models. DISCUSSION: This systematic review will provide a synthesis of evidence on the association between SDH and pediatric trauma care (access to care and quality of care) that clinicians and policymakers can use to better tailor care systems and promote equitable access and quality of care for all children. We will share our findings through clinical rounds, conferences, and publication in a peer-reviewed journal. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42023408467.

The use of early neuromuscular blockage in acute respiratory distress syndrome: A systematic review and meta-analyses of randomized clinical trials.

BACKGROUND: Acute Respiratory Distress Syndrome (ARDS) as defined by the Berlin definition has an approximate mortality rate of 40% and no curative treatment. Mutliple therapies have been studied to reduce mortality but only neuromuscular blocking agents show potential benefits on mortality and other complications of ARDS. OBJECTIVE: This review aimed to investigate the efficacy of neuromuscular blockers in ARDS METHODS: Medline, Embase, Cochrane Central and Web of Science were queried on October 1st, 2021. Randomized clinical trials comparing neuromuscular blockers to any comparator in treating ARDS were included. Primary outcome was mortality. Secondary outcomes were ventilator-free days, intensive care (ICU) length of stay (LOS) and complications. Results between sedation levels were examined with a Bayesian Network for Meta-analysis method. RESULTS: We included 6 trials compiling a total of 1557 patients. Neuromuscular blockers compared to any comparator in treating ARDS showed a reduction in mortality (RR 0.79 [95% CI, 0.62 to 0.99]). No difference in ventilator-free days (MD 0.68 [95% CI, -0.50 to 1.85]) or ICU LOS (MD 0.77 [95% CI, -2.99 to 4.54]) were found. A Bayesian Network Meta-analysis yielded no difference in mortality when using light sedation compared to heavy sedation in ARDS. (OR 0.58 [95% CrI, 0.07 to 4.46].) CONCLUSION: Neuromuscular blockers safely reduce mortality. Light sedation potentially has a similar impact on mortality as heavy sedation that carries some burden. A non-inferiority trial comparing both sedation levels may be warranted considering the added value of light sedation.

Effect of Intermittent Pneumatic Compression in Addition to Pharmacologic Prophylaxis for Thromboprophylaxis in Hospitalized Adult Patients: A Systematic Review and Meta-Analysis.

Venous thromboembolic events (VTE) are frequent complications in hospitalized patients and a leading cause of preventable death in hospital. Pharmacologic prophylaxis is a standard of care to prevent VTE in patients at risk, the additional value of intermittent pneumatic compression (IPC) is uncertain. We aimed to evaluate the efficacy of adding IPC to pharmacologic prophylaxis to prevent VTE in hospitalized adults. DATA SOURCES: We searched the Cochrane Central Register of Controlled Trials, Embase, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, ClinicalTrials.gov, and the International Clinical Trials Registry Platform from inception to July 2022. STUDY SELECTION: We included randomized controlled trials comparing the use of IPC in addition to pharmacological thromboprophylaxis to pharmacological thromboprophylaxis alone in hospitalized adults. DATA EXTRACTION: Meta-analyses were performed to calculate risk ratio (RR) of VTE, deep venous thrombosis (DVT), and pulmonary embolism (PE). We assessed the risk of bias using the Cochrane Risk of Bias Tool for Randomized Trials, Version 2 and the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach. DATA SYNTHESIS: We included 17 trials enrolling 8,796 participants. The IPC was mostly applied up to the thigh and pharmacological thromboprophylaxis was primarily low-molecular-weight heparin. Adjunctive IPC was associated with a decreased risk of VTE (15 trials, RR = 0.53; 95% CI [0.35-0.81]) and DVT (14 trials, RR = 0.52; 95% CI [0.33-0.81]) but not PE (seven trials, RR = 0.73; 95% CI [0.32-1.68]). The quality of evidence was graded low, downgraded by risk of bias and inconsistency. Moderate and very low-quality evidence, respectively, suggests that adjunctive IPC is unlikely to change the risk of all-cause mortality or adverse events. Subgroup analyses indicate a more evident apparent benefit in industry-funded trials. CONCLUSIONS: Results indicate low-quality evidence underpinning the additional use of IPC to pharmacological thromboprophylaxis for prevention of VTE and DVT. Further large high-quality randomized trials are warranted to support its use and to identify patient subgroups for whom it could be beneficial.

Economic Evaluation of In-Hospital Clinical Practices in Acute Injury Care: A Systematic Review.

OBJECTIVES: Underuse of high-value clinical practices and overuse of low-value practices are major sources of inefficiencies in modern healthcare systems. To achieve value-based care, guidelines and recommendations should target both underuse and overuse and be supported by evidence from economic evaluations. We aimed to conduct a systematic review of the economic value of in-hospital clinical practices in acute injury care to advance knowledge on value-based care in this patient population. METHODS: Pairs of independent reviewers systematically searched MEDLINE, Embase, Web of Science, and Cochrane Central Register for full economic evaluations of in-hospital clinical practices in acute trauma care published from 2009 to 2019 (last updated on June 17, 2020). Results were converted into incremental net monetary benefit and were summarized with forest plots. The protocol was registered with PROSPERO (CRD42020164494). RESULTS: Of 33 910 unique citations, 75 studies met our inclusion criteria. We identified 62 cost-utility, 8 cost-effectiveness, and 5 cost-minimization studies. Values of incremental net monetary benefit ranged from international dollars -467 000 to international dollars 194 000. Of 114 clinical interventions evaluated (vs comparators), 56 were cost-effective. We identified 15 cost-effective interventions in emergency medicine, 6 in critical care medicine, and 35 in orthopedic medicine. A total of 58 studies were classified as high quality and 17 as moderate quality. From studies with a high level of evidence (randomized controlled trials), 4 interventions were clearly dominant and 8 were dominated. CONCLUSIONS: This research advances knowledge on value-based care for injury admissions. Results suggest that almost half of clinical interventions in acute injury care that have been studied may not be cost-effective.

Clinical services in community pharmacies: a scoping review of policy and social implications.

OBJECTIVES: Clinical services have allowed pharmacists to shift from product-oriented to patient-oriented services. However, the policy and social implications of clinical services in community pharmacies are not well described. The purpose of this scoping review was to identify these implications. KEY FINDINGS: We searched Pubmed and Embase, from inception to March 2019, as well as grey literature for publications that discussed policy (e.g. pharmacy model and pharmacist status) or social (e.g. role of pharmacists and interprofessional collaboration) implications of clinical services. Publications had to address clinical services provided by pharmacists in community settings that target the global long-term care of patients. We extracted data related to the implications and classified them into themes thereafter. The search process identified 73 relevant publications, of which 13 were included in regard to policy implications and 60 relative to social implications. Two themes emerged from policy implications: implementation and characteristics of policies, and professional status. Pharmacists' independence from distribution, financial coverage of clinical services and innovative models of practice were addressed. Social implications involved three themes: roles and interprofessional collaboration, changes in practice and barriers and model of practices and services. Perceptions of pharmacists' skills, organisational barriers, time constraints, lack of self-confidence and cultural shifts required to implement clinical services were included in these themes. SUMMARY: Our review demonstrates the changing role of community pharmacists in provision of clinical services within the healthcare system. The range of clinical services varies widely from one setting to another. The context of community pharmacy is not well suited to these changes in practice.

Complexation of triptolide and its succinate derivative with cyclodextrins: affinity capillary electrophoresis, isothermal titration calorimetry and 1H NMR studies.

The complexation of the triptolide PG490 and its succinate derivative PG490-88Na with various cyclodextrins was studied using three complementary techniques: affinity capillary electrophoresis (ACE), isothermal titration calorimetry (ITC) and nuclear magnetic resonance (NMR). The apparent binding constants of the complexes formed between the drugs and 8 CDs (α-CD, ß-CD, γ-CD, HP-α-CD, HP-ß-CD, HP-γ-CD, CM-ß-CD and amino-ß-CD) were determined by ACE through linear Scott's plots. The apparent and averaged binding constants of the complexes formed between PG490-88 and ß-CD, γ-CD, HP-α-CD, HP-ß-CD or HP-γ-CD are contained in the narrow range 135-167 M(-1). For the anionic CM-ß-CD and cationic amino-ß-CD, these constants are 38 and 278 M(-1), respectively, which is in accordance with electrostatic repulsions or attractions with the succinate moiety. ITC and NMR investigations for the binding constants determinations were performed for 2 CDs allowing high complexation: HP-ß-CD and amino-ß-CD. The three techniques provided similar results. ITC and NMR, in contrast to ACE, allowed to study the complexes formed between the neutral compound PG490 and neutral cyclodextrins. A more advanced characterization of the PG 490-88Na/amino-ß-CD complex, which displays the highest apparent binding constant, was undertaken using NMR spectroscopy. The 1:1 stoichiometry of the complex was established by (1)H NMR 1D and selective 1D TOCSY experiments using the continuous variation method. Moreover, the 1D and 2D ROESY experiments revealed the inclusion of the isopropyl moiety of the triptolide derivative in the hydrophobic CD cavity. Altogether, the data provide strong evidences that the two triptolide compounds can be efficiently complexed with CD.
