Shatapaki Ksheerbala Taila (SKT) is a herbal formulation in oil form which is used for treating central nervous system disorders, rheumatism and insomnia. The current study was conducted in Wistar rats for evaluating the effect of Shatapaki Ksheerbala Taila (SKT) on Central Nervous System (CNS). The study drug was given in the dosage of 0.9mL/kg and 9 mL/kg body weight. Diazepam 3mg/kg body weight was used as standard drug. It was observed that the administration of SKT to rats significantly changes their behavioural pattern, indicating the modulation of CNS activity by SKT. [ABSTRACT FROM AUTHOR]

Background:The use of interosseous wire to fix bone grafts is well known. Herein, we describe a technique for fixation of an iliac crest bone graft for nasal augmentation, using a stainless steel wire.Method:A hole in the cancellous part of the graft guides the wire exactly into a groove in the cortical part, preventing slippage and ensuring rigid fixation. The wire is then threaded through a hollow spinal needle passed underneath the skin envelope; this avoids a dorsal incision and thus minimises scarring, reduces the risk of graft exposure and improves the aesthetic result.Results:This technique has two distinct advantages: prevention of wire slippage and avoidance of a dorsal nasal incision.Conclusion:The described method uses an interosseous wire for rigid bone graft fixation, without a dorsal incision. This prevents wire slippage; it also achieves a good cosmetic result by improving the nasal contour via a cantilever effect which raises the nasal tip. [ABSTRACT FROM PUBLISHER]

Plants have been the basis of many traditional medicines throughout the world for thousands of years and continue to provide new remedies to mankind. Plants have been one of the important sources of medicines since the beginning of human civilization. The recent resurgence of plant remedies resulted from several factors, such as effectiveness of plant medicines and lesser side effects compared with modern medicines. Psoralea corylifolia, commonly known as babchi, is a popular herb, which has since long been used in traditional Ayurvedic and Chinese medicine for its magical effects to cure various skin diseases. This plant is also pharmacologically studied for its chemoprotective, antioxidant, antimicrobial, and antiinfl ammatory properties. This review attempts to highlight the available literature on P. corylifolia with respect to its ethnobotany, pharmacognostic characteristics, traditional uses, chemical constituents, and summary of its various pharmacologic activities and clinical effects. Other aspects, such as toxicology and precautions are also discussed. This will be helpful to create interest toward babchi and may be useful in developing new formulations with more therapeutic and economical value. [ABSTRACT FROM AUTHOR]

Abstract Background Antigenic chimeric viruses have previously been generated in which the structural genes of recombinant dengue virus type 4 (rDEN4) have been replaced with those derived from DEN2 or DEN3. Two vaccine candidates were identified, rDEN2/4Δ30(ME) and rDEN3/4Δ30(ME), which contain the membrane (M) precursor and envelope (E) genes of DEN2 and DEN3, respectively, and a 30 nucleotide deletion (Δ30) in the 3' untranslated region of the DEN4 backbone. Based on the promising preclinical phenotypes of these viruses and the safety and immunogenicity of rDEN2/4Δ30(ME) in humans, we now describe the generation of a panel of four antigenic chimeric DEN4 viruses using either the capsid (C), M, and E (CME) or ME structural genes of DEN1 Puerto Rico/94 strain. Results Four antigenic chimeric viruses were generated and found to replicate efficiently in Vero cells: rDEN1/4(CME), rDEN1/4Δ30(CME), rDEN1/4(ME), and rDEN1/4Δ30(ME). With the exception of rDEN1/4(ME), each chimeric virus was significantly attenuated in a SCID-HuH-7 mouse xenograft model with a 25-fold or greater reduction in replication compared to wild type DEN1. In rhesus monkeys, only chimeric viruses with the Δ30 mutation appeared to be attenuated as measured by duration and magnitude of viremia. rDEN1/4Δ30(CME) appeared over-attenuated since it failed to induce detectable neutralizing antibody and did not confer protection from wild type DEN1 challenge. In contrast, rDEN1/4Δ30(ME) induced 66% seroconversion and protection from DEN1 challenge. Presence of the Δ30 mutation conferred a significant restriction in mosquito infectivity upon rDEN1/4Δ30(ME) which was shown to be non-infectious for Aedes aegypti fed an infectious bloodmeal. Conclusion The attenuation phenotype in SCID-HuH-7 mice, rhesus monkeys, and mosquitoes and the protective immunity observed in rhesus monkeys suggest that rDEN1/4Δ30(ME) should be considered for evaluation in a clinical trial.

Objective: To identify evidence syntheses of health interventions addressing racial health equity reporting the use of equity-focused frameworks and logic models., Study Design and Setting: The search strategy included three sources; a search of three bibliographic databases to identify systematic reviews assessing interventions to improve racial health equity, semi-structured interviews with diverse group and a targeted organization website searches (e.g. NIH, USPSTF) to identify relevant logic models and frameworks. The searches were conducted between January 1, 2020, and January 25, 2023. We used a qualitative approach to identify and describe key characteristics of equity-focused logic models and frameworks used in evidence syntheses., Results: Of the 153 racial health equity-focused evidence syntheses identified, 2 explicitly used logic models to describe the intervention mechanism. We identified seven existing health equity frameworks from semi-structured interviews and electronic search of key websites that were categorized by stated purpose as providing guidance for 1) research, 2) health policy, 3) digital healthcare solutions, and 4) clinical preventive services. Two out of 7 frameworks included guidance on integrating frameworks or logic models in evidence synthesis while the majority provided contextual information on how to define or consider race or racism as a structural determinant of health., Conclusion: There is limited use of logic models and frameworks in evidence syntheses addressing racial health equity. There is a need for more applied frameworks providing guidance for framing, conducting and interpreting findings of evidence syntheses addressing racial health equity., (Copyright © 2024 The Author(s).

Objectives: In the context of profound and persistent racial health inequities, we sought to understand how to define racial health equity in the context of systematic reviews and how to staff, conduct, disseminate, sustain, and evaluate systematic reviews that address racial health equity., Study Design and Setting: The study consisted of virtual, semistructured interviews followed by structured coding and qualitative analyses using NVivo., Results: Twenty-nine individuals, primarily United States-based, including patients, community representatives, systematic reviewers, clinicians, guideline developers, primary researchers, and funders, participated in this study. These interest holders brought up systems of power, injustice, social determinants of health, and intersectionality when conceptualizing racial health equity. They also emphasized including community members with lived experience in review teams. They suggested making changes to systematic review scope, methods, and eligible evidence (such as adapting review methods to include racial health equity considerations in prioritizing topics for reviews, formulating key questions and searches, and specifying outcomes) and broadening evidence to include designs that address implementation and access. Interest holders noted that sustained efforts to center racial health equity in systematic reviews require resources, time, training, and demonstrating value to funders., Conclusion: Interest holders identified changes to the funding, staffing, conduct, dissemination, and implementation of systematic reviews to center racial health equity. Action on these steps requires clear standards for success, an evidence base to support transformative changes, and consensus among interest holders on the way forward., Competing Interests: Declaration of competing interest There are no competing interests for any author., (Copyright © 2024 The Authors.

Aim -To isolate bacteriophages targeting extended-spectrum beta-lactamase-producing K. pneumoniae and evaluate their effectiveness across diverse models, incorporating innovative alternatives in animal testing., Methods and Results: vB_kpnS-Kpn15 was isolated from sewage sample from Thane district. It produced a clear plaques on K. pneumoniae ATCC 700603. It has a flexible, non-contractile long tail and an icosahedral head and the Siphoviridae family of viruses in the order Caudovirales matched all of its structural criteria. Sequencing of vB_kpnS-Kpn15 revealed a 48,404 bp genome. The vB_KpnS-Kpn15 genome was found to contain 50 hypothetical proteins, of which 16 were found to possess different functions. The vB_KpnS-Kpn15 was also found to possess enzymes for its DNA synthesis. It was found to be lytic for the planktonic cells of K. pneumoniae and bactericidal for up to 48 h and potentially affected established K. pneumoniae biofilms. It demonstrated a broad host range and caused lytic zones on about 46 % of K. pneumoniae multi-drug resistant strains. In an in vitro wound and burn infection model, phage vB_kpnS-Kpn15 in combination with other phages resulted in successful cell proliferation and wound healing. Based on vB_kpnS-Kpn15's lytic properties, it can be incorporated in a bacteriophage cocktail to combat ESBL strains., Conclusions: The phages isolated during this research are better candidates for phage therapy, and therefore provide new and exciting options for the successful control of antibiotic-resistant bacterial infections in the future. The utilization of animal alternative models in this study elucidates cellular proliferation and migration, underscoring its significance in screening novel drugs with potential applications in the treatment of wound and burn infections., Significance and Impact of the Research: The findings of this research have implications for the creation of innovative, promising strategies to treat ESBL K. pneumoniae infections., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Importance: Despite evidence that most upper respiratory infections (URIs) are due to viruses, antibiotics are frequently prescribed for this indication in the outpatient setting. Antibiotic stewardship strategies are needed to reduce adverse patient outcomes and staggering healthcare costs due to resistant infections that ensue from inappropriate prescriptions., Objective: To determine if individual provider scorecards detailing antibiotic prescribing rates paired with educational resources reduce inappropriate antibiotic use for URIs in the outpatient primary care setting., Design, Setting and Participants: This quality improvement project investigated the number of URI-coded office visits in the primary care setting over three consecutive influenza seasons, which resulted in an antibiotic prescription in Cooper University Healthcare's 14 primary care offices. We compared provider's individual prescribing patterns to their peers' average and created a scorecard that was shared with each provider over a series of intervention phases. Data were collected from a preintervention period (November 2017-February 2018), and two postintervention phases, phase I (November 2018-February 2019) and phase II (November 2019-February 2020)., Intervention: A personalised, digital scorecard containing antibiotic-prescribing data for URI-coded visits from the prior influenza season was emailed to each primary care provider. Prior to the subsequent influenza season, prescribers received their updated prescribing rates as well as peer-to-peer comparisons. In both phases, the scorecard was attached to an email with antimicrobial stewardship educational materials., Main Outcomes and Measures: The primary outcome was a reduction in the number of inappropriate antibiotic prescriptions for URI-related diagnoses. The diagnoses were organised into five broad coding categories, including bronchitis, sinusitis, sore throat excluding strep, influenza and tonsillitis excluding strep., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Purpose: Previous work has identified two AKI sub-phenotypes (SP1 and SP2) characterized by differences in inflammation and endothelial dysfunction. Here we identify these sub-phenotypes using biospecimens collected in the emergency department and test for differential response to restrictive versus liberal fluid strategy in sepsis-induced hypotension in the CLOVERS trial., Methods: We applied a previously validated 3-biomarker model using plasma angiopietin-1 and 2, and soluble tumor necrosis factor receptor-1 to classify sub-phenotypes in patients with kidney dysfunction (AKI or end-stage kidney disease [ESKD]). We also compared a de novo latent class analysis (LCA) to the 3-biomarker based sub-phenotypes. Kaplan-Meier estimates were used to test for differences in outcomes and sub-phenotype by treatment interaction., Results: Among 1289 patients, 846 had kidney dysfunction on enrollment and the 3-variable prediction model identified 605 as SP1 and 241 as SP2. The optimal LCA model identified two sub-phenotypes with high correlation with the 3-biomarker model (Cohen's Kappa 0.8). The risk of 28 and 90-day mortality was greater in SP2 relative to SP1 independent of AKI stage and SOFA scores. Patients with SP2, characterized by more severe endothelial injury and inflammation, had a reduction in 28-day mortality with a restrictive fluid strategy versus a liberal fluid strategy (26% vs 41%), while patients with SP1 had no difference in 28-day mortality (10% vs 11%) ( p-value-for-interaction = 0.03)., Conclusion: Sub-phenotypes can be identified in the emergency department that respond differently to fluid strategy in sepsis. Identification of these sub-phenotypes could inform a precision-guided therapeutic approach for patients with sepsis-induced hypotension and kidney injury.

Importance: The United States Preventive Services Task Force (USPSTF) has considered the topic of prevention of child maltreatment multiple times over its nearly 40-year history, each time reaching the conclusion that the evidence is insufficient to recommend for or against interventions aimed at preventing this important health problem with significant negative sequelae before it occurs. In the most recent evidence review, which was conducted from August 2021 to November 2023 and published in March 2024, the USPSTF considered contextual questions on the evidence for bias in reporting and diagnosis of maltreatment in addition to key questions regarding effectiveness of interventions to prevent child maltreatment., Observations: A comprehensive literature review found evidence of inaccuracies in risk assessment and racial and ethnic bias in the reporting of child maltreatment and in the evaluation of injuries concerning for maltreatment, such as skull fractures. When children are incorrectly identified as being maltreated, harms, such as unnecessary family separation, may occur. Conversely, when children who are being maltreated are missed, harms, such as ongoing injury to the child, continue. Interventions focusing primarily on preventing child maltreatment did not demonstrate consistent benefit or information was insufficient. Additionally, the interventions may expose children to the risk of harm as a result of these inaccuracies and biases in reporting and evaluation. These inaccuracies and biases also complicate assessment of the evidence for making clinical prevention guidelines., Conclusions and Relevance: There are several potential strategies for consideration in future efforts to evaluate interventions aimed at the prevention of child maltreatment while minimizing the risk of exposing children to known biases in reporting and diagnosis. Promising strategies to explore might include a broader array of outcome measures for addressing child well-being, using population-level metrics for child maltreatment, and assessments of policy-level interventions aimed at improving child and family well-being. These future considerations for research in addressing child maltreatment complement the USPSTF's research considerations on this topic. Both can serve as guides to researchers seeking to study the ways in which we can help all children thrive.

Importance: Interventions that address needs such as low income, housing instability, and safety are increasingly appearing in the health care sector as part of multifaceted efforts to improve health and health equity, but evidence relevant to scaling these social needs interventions is limited., Objective: To summarize the intensity and complexity of social needs interventions included in randomized clinical trials (RCTs) and assess whether these RCTs were designed to measure the causal effects of intervention components on behavioral, health, or health care utilization outcomes., Evidence Review: This review of a scoping review was based on a Patient-Centered Outcomes Research Institute-funded evidence map of English-language US-based RCTs of social needs interventions published between January 1, 1995, and April 6, 2023. Studies were assessed for features related to intensity (defined using modal values as providing as-needed interaction, 8 participant contacts or more, contacts occurring every 2 weeks or more often, encounters of 30 minutes or longer, contacts over 6 months or longer, or home visits), complexity (defined as addressing multiple social needs, having dedicated staff, involving multiple intervention components or practitioners, aiming to change multiple participant behaviors [knowledge, action, or practice], requiring or providing resources or active assistance with resources, and permitting tailoring), and the ability to assess causal inferences of components (assessing interventions, comparators, and context)., Findings: This review of a scoping review of social needs interventions identified 77 RCTs in 93 publications with a total of 135 690 participants. Most articles (68 RCTs [88%]) reported 1 or more features of high intensity. All studies reported 1 or more features indicative of high complexity. Because most studies compared usual care with multicomponent interventions that were moderately or highly dependent on context and individual factors, their designs permitted causal inferences about overall effectiveness but not about individual components., Conclusions and Relevance: Social needs interventions are complex, intense, and include multiple components. Our findings suggest that RCTs of these interventions address overall intervention effectiveness but are rarely designed to distinguish the causal effects of specific components despite being resource intensive. Future studies with hybrid effectiveness-implementation and sequential designs, and more standardized reporting of intervention intensity and complexity could help stakeholders assess the return on investment of these interventions.

Importance: Child maltreatment is associated with serious negative physical, psychological, and behavioral consequences., Objective: To review the evidence on primary care-feasible or referable interventions to prevent child maltreatment to inform the US Preventive Services Task Force., Data Sources: PubMed, Cochrane Library, and trial registries through February 2, 2023; references, experts, and surveillance through December 6, 2023., Study Selection: English-language, randomized clinical trials of youth through age 18 years (or their caregivers) with no known exposure or signs or symptoms of current or past maltreatment., Data Extraction and Synthesis: Two reviewers assessed titles/abstracts, full-text articles, and study quality, and extracted data; when at least 3 similar studies were available, meta-analyses were conducted., Main Outcomes and Measures: Directly measured reports of child abuse or neglect (reports to Child Protective Services or removal of the child from the home); proxy measures of abuse or neglect (injury, visits to the emergency department, hospitalization); behavioral, developmental, emotional, mental, or physical health and well-being; mortality; harms., Results: Twenty-five trials (N = 14 355 participants) were included; 23 included home visits. Evidence from 11 studies (5311 participants) indicated no differences in likelihood of reports to Child Protective Services within 1 year of intervention completion (pooled odds ratio, 1.03 [95% CI, 0.84-1.27]). Five studies (3336 participants) found no differences in removal of the child from the home within 1 to 3 years of follow-up (pooled risk ratio, 1.06 [95% CI, 0.37-2.99]). The evidence suggested no benefit for emergency department visits in the short term (<2 years) and hospitalizations. The evidence was inconclusive for all other outcomes because of the limited number of trials on each outcome and imprecise results. Among 2 trials reporting harms, neither reported statistically significant differences. Contextual evidence indicated (1) widely varying practices when screening, identifying, and reporting child maltreatment to Child Protective Services, including variations by race or ethnicity; (2) widely varying accuracy of screening instruments; and (3) evidence that child maltreatment interventions may be associated with improvements in some social determinants of health., Conclusion and Relevance: The evidence base on interventions feasible in or referable from primary care settings to prevent child maltreatment suggested no benefit or insufficient evidence for direct or proxy measures of child maltreatment. Little information was available about possible harms. Contextual evidence pointed to the potential for bias or inaccuracy in screening, identification, and reporting of child maltreatment but also highlighted the importance of addressing social determinants when intervening to prevent child maltreatment.

SARS-CoV-2, severe acute respiratory syndrome coronavirus-2, causes coronavirus disease- 2019 (COVID-19). Mostly, COVID-19 causes respiratory symptoms that can resemble those of a cold, the flu, or pneumonia. COVID-19 may harm more than just lungs and respiratory systems. It may also have an impact on other parts of the body and debilitating effects on humans, necessitating the development of vaccines at an unprecedented rate in order to protect humans from infections. In response to SARS-CoV-2 infection, mRNA, viral vector-based carrier and inactivated virus-based vaccines, as well as subunit vaccines, have recently been developed. We developed Relcovax®, a dual antigen (Receptor binding domain (RBD) and Nucleocapsid (N) proteins) subunit protein vaccine candidate. Preliminary mouse preclinical studies revealed that Relcovax® stimulates cell-mediated immunity and provides broader protection against two SARS-CoV-2 variants, including the delta strain. Before conducting human studies, detailed preclinical safety assessments are required, so Relcovax® was tested for safety, and immunogenicity in 28-day repeated dose toxicity studies in rats and rabbits. In the toxicity studies, there were no mortality or morbidity, abnormal clinical signs, abnormalities in a battery of neurobehavioral observations, abnormalities in detailed clinical and ophthalmological examinations, or changes in body weights or feed consumption. In any of the studies, no abnormal changes in organ weights, haematology, clinical chemistry, urinalysis parameters, or pathological findings were observed. Immunogenicity tests on rats and rabbits revealed 100 % seroconversion. Relcovax® was therefore found to be safe in animals, with a No Observed Adverse Effect Level (NOAEL) of 20 µg/protein in rats and rabbits. In efficacy studies, Relcovax® immunised hamsters demonstrated dose-dependent protection against SARS-CoV-2 infection, with a high dose (20 µg/protein) being the most protective, while in cynomolgus macaque monkey study, lowest dose 5 µg/protein had the highest efficacy. In conclusion, Relcovax® was found to be safe, immunogenic, and efficacious in in vivo studies., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: [Venkata Ramana, Praveen Rao, Abhishek Phetarphekar, Gopala Karanam, Girish Masand, Ramnath Lakshmanan has patent #WO/2023/017536 issued to Reliance Life Sciences Pvt.

Objectives: The G8 is a well-validated screening test for older cancer patients. The current study was undertaken to determine whether the G8 is predictive of short-term post-operative outcomes after head and neck cancer (HNC) surgery., Methods: Consecutive patients aged 65 years or more and referred for a preoperative assessment by a speech-language pathologist were consecutively screened by clinicians at 2 academic medical centers using the G8. The G8 was used to screen for vulnerability prior to surgery. Patients were deemed vulnerable if they had a total G8 score ≤14 according to published guidelines. Data were also collected on demographic characteristics, tumor staging, post-operative course, and tracheostomy and feeding tube (FT) status., Results: Ninety patients were consecutively screened during the study period. Using the G8, 64% of the patients were deemed vulnerable. Vulnerable patients differed significantly from non-vulnerable patients with regard to age, health, tumor stage, and baseline dysphagia, and underwent more extensive surgery. Postoperatively, vulnerable patients had a significantly longer hospital length of stay (LOS; 10.17 vs 5.50 days, respectively, P  < .001), were less likely to discharge home (76% vs 94%, P  = .044), and were more likely to be FT dependent for over a month (54% vs 21%, P  = .006) compared to non-vulnerable patients. In regression models, controlling for T-stage and surgical variables, the G8 independently predicted 2 post-operative outcomes of interest, namely LOS and FT dependency., Conclusions: The G8 may be a useful screening tool for identifying older adults at risk of a protracted postoperative medical course after HNC surgery. Future research should aim to identify the optimal screening protocol and how this information can be incorporated into clinical pathways to enhance the post-operative outcomes of older HNC patients., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Botanicals are increasingly incorporated into skincare products. Although allergic contact dermatitis due to botanicals is recognized, data describing the prevalence of positive patch tests to botanicals are sparse. Objective: To report the Mayo Clinic experience of patch testing to selected botanical products in the standard, extended standard, fragrance, and plant series. Methods: IRB-approved retrospective study of the Mayo Clinic experience with patch testing to botanicals from 1997 to 2017. Results: In total, 12,169 people were patch tested to botanicals in the standard, extended standard, fragrance, and plant series; 4032 were men and 8137 were women. The mean age of the population tested was 54 (standard deviation 17.7) years. Almost 11% (1320/12,169) of the patch-tested population exhibited positive reactions to at least 1 botanical agent. Myroxylon pereirae resin 25% was the most common positive allergen in the series. Patients who had positive reactions to at least 1 botanical agent were more (19.8%) likely to have a positive reaction to at least 1 additional botanical than those patients who did not have any positive tests. Most patients presented with generalized involvement (334) or involvement of the hands (284) or face (232). Conclusion: Physicians should be aware of the high prevalence of allergic contact dermatitis and patch test positivity associated with botanical products.

The thyroid, a gland with a butterfly-like shape in the base of the human neck, plays an important role in metabolism. Body heat, energy levels, weight, hair, fingernail, and regular menstruation cycles are controlled by three hormones produced by the thyroid. A system of feedback regulates the release of those hormones. Overproduction as well as underproduction of thyroid hormones can result from shifts in the stimulation and regulation of those hormones. These factors can have physiological or pathological origins. Pregnancy is a physiological factor. There is a plethora of physiological and psychological shifts that occur during pregnancy. A thyroid alteration in the mother is one example. Thyroid irregularities result from a failure to adjust to new circumstances. Thyroid hormone levels can drop, or manufacturing could be slowed during pregnancy due to variations in hormone concentration. Hypothyroidism describes this disorder. Hypothyroidism in women who are pregnant is either gestational or could be a disorder that is present before pregnancy. Gestational hypothyroidism cures itself throughout postpartum times, though it can stay as subclinical hyperthyroidism for some time after delivery. They pose a serious risk to development, stunt the growth of the unborn child and lead to defects in subsequent generations. Enhanced thyroid binding globulin levels, enhanced iodine clearance by the kidneys, modified effects of the human reproductive hormone and reduced dietary consumption of iodine lead to these alterations in the gland. Cretinism and mental disorders are among the serious health problems related to an iodine imbalance in maternal hypothyroidism. The growth of the brain, nervous system and Intelligence of an unborn child depends on thyroid hormones. As a result, normal early stages of development suffer due to changes in maternal hormone levels.

Background: In the USA, access to quality healthcare varies greatly across racial and ethnic groups, resulting in significant health disparities. A new term, "racial health equity" (RHE), is increasingly reported in the medical literature, but there is currently no consensus definition of the term. Additionally, related terms such as "health disparities," "health inequities," and "equality" have been inconsistently used when defining RHE., Methods: The primary purpose of this scoping review is to investigate the current use and underlying concepts used to define racial health equity. The study will address two key questions: (1) "What terminology and definitions have been used to characterize RHE?" and (2) "What knowledge gaps and challenges are present in the current state of RHE research and theory?" The review will collect and analyze data from three sources: (1) websites from key national and international health organizations, (2) theoretical and narrative published articles, and (3) evidence synthesis studies addressing interventions targeting racial health equity and minority stakeholder engagement., Discussion: Defining "racial health equity" and related terminology is the first step to advancing racial health equity within the USA. This review aims to offer an improved understanding of RHE constructs and definitions, bringing greater unity to national racial health equity research efforts across disciplines., Systematic Review Registration: This protocol is registered with the Open Science Framework at https://osf.io/7pvzq ., (© 2023.
