The Impact of Prescription Drug Coverage on Disparities in Adherence and Medication Use: A Systematic Review.

Prescription drug cost-sharing is a barrier to medication adherence, particularly for low-income and minority populations. In this systematic review, we examined the impact of prescription drug cost-sharing and policies to reduce cost-sharing on racial/ethnic and income disparities in medication utilization. We screened 2,145 titles and abstracts and identified 19 peer-reviewed papers that examined the interaction between cost-sharing and racial/ethnic and income disparities in medication adherence or utilization. We found weak but inconsistent evidence that lower cost-sharing is associated with reduced disparities in adherence and utilization, but studies consistently found that significant disparities remained even after adjusting for differences in cost-sharing across individuals. Study designs varied in their ability to measure the causal effect of policy or cost-sharing changes on disparities, and a wide range of policies were examined across studies. Further research is needed to identify the types of policies that are best suited to reduce disparities in medication adherence.

The effect of oral nutrition supplements and appetite stimulants on weight status among pediatric cancer patients: A systematic review.

The objective of this study was to identify the use and impact of oral nutrition supplements (ONSs) and appetite stimulants on weight status among pediatric patients diagnosed with malignancy. We performed a literature search of trials using Medline PubMed, CINAHL, Web of Science Core Collection, Scopus, and Cochrane Database of Systematic Reviews and included all prospective studies except review articles and case-reports/series that assessed ONSs or appetite stimulants among patients (0-20 years old) diagnosed with a pediatric malignancy. Databases were searched through May 17, 2022. There were six trials included with three studies related to ONS and the remaining on appetite stimulants. No studies that compared both ONS and appetite stimulants were found. To assess quality, we used the Risk of Bias in Nonrandomized Studies of Interventions and the Revised Cochrane Risk of Bias Tool for Randomized Trials depending on the study design. The studies all had pediatric patients diagnosed with a variety of malignancy types. All studies demonstrated improvement of weight status in the treatment group across various malignancy types. However, none of the studies addressed nutrition intakes outside of ONS consumption, compliance to ONSs, or frequency of ONS use. Despite the short durations (3-6 months) and significant differences in the timing of intervention initiation (ONS or appetite stimulants), these treatment modalities can improve weight status. Further research is needed to identify the best intervention for improving weight status.

Frequency and Types of Healthcare Encounters in the Week Preceding a Sepsis Hospitalization: A Systematic Review.

OBJECTIVES: Early recognition and treatment are critical to improving sepsis outcomes. We sought to identify the frequency and types of encounters that patients have with the healthcare system in the week prior to a sepsis hospitalization. DATA SOURCES: PubMed, Cumulative Index to Nursing and Allied Health Literature, Scopus, and the Cochrane Library. STUDY SELECTION: Observational cohort studies of patients hospitalized with sepsis or septic shock that were assessed for an outpatient or emergency department encounter with the healthcare system in the week prior to hospital admission. DATA EXTRACTION: The primary outcome was the proportion of patients with a healthcare encounter in the time period assessed (up to 1 week) prior to a hospitalization with sepsis. DATA SYNTHESIS: Six retrospective observational studies encompassing 6,785,728 sepsis admissions were included for evaluation, ranging from a 263-patient single-center cohort to a large database evaluating 6,731,827 sepsis admissions. The average (unweighted) proportion of patients having an encounter with the healthcare system in the week prior to a sepsis hospitalization was 32.7% and ranged from 10.3% to 52.9%. These encounters commonly involved presentation or potential symptoms of infectious diseases, antibiotic prescriptions, and appeared to increase in frequency closer to a sepsis hospitalization admission. No consistent factors were identified that distinguished a healthcare encounter as more or less likely to precede a sepsis hospitalization in the subsequent week. CONCLUSIONS: Patients that present to the hospital with sepsis are frequently evaluated in the healthcare system in the week prior to admission. Further research is necessary to understand if these encounters offer earlier opportunities for intervention to prevent the transition from infection to sepsis, whether they merely reflect the comorbidities of sepsis patients with a high baseline rate of healthcare encounters, or the declining trajectory of a patient's overall health in response to infection.

Scoping Review: Ethical Considerations in Online Ethnographic Research With Military Populations.

Researchers using online ethnographic methods to study military communities must employ higher standards of ethical practice. Military populations may face significant risk if reidentified in research. These requirements are especially salient for online data collection. This review questions how and to what extent military online ethnographers are addressing ethics considerations. We charted evidence from seven military studies using an online ethnographic method. Findings reveal that most online military ethnographers did not utilize sufficient ethical safeguards in their studies. Additionally, they did not document or transparently disclose the ethical steps they may have taken. This study argues implementing ethical safeguards is especially important for protecting vulnerable military populations. We present a strategy for evaluating ethics practices in online ethnographic research and provide best practices for military online ethnographers.

Health-Related Quality of Life After Polytrauma: A Systematic Review.

BACKGROUND: Following hospital discharge after traumatic injuries, many patients' rehabilitation is inhibited by poor health-related quality of life (HRQoL). OBJECTIVE: The purpose of this review is to identify factors that influence the HRQoL of polytrauma patients after hospital discharge. METHODS: A systematic literature search was performed in CINAHL and PubMed databases for English-language articles published between January 2015 and January 2020. Articles that dealt with pediatric or narrow adult populations, exclusively considered brain and spinal cord injuries, burn injuries, or isolated fractures were excluded. In total, 22 nonexperimental cohort studies were eligible for inclusion. RESULTS: Based on these studies, with minor disagreements explainable by deficient sampling, variables that impacted HRQoL fell into 11 categories: demographics, preinjury HRQoL, preexisting conditions, mental health status, injury type and location, injury severity, course of hospitalization, time after injury, financial and employment status, functional capacity, and pain. CONCLUSION: The finding with the greatest implications was that mental health, positive coping, self-efficacy, and perception of physical state significantly influence HRQoL after injury and, along with other modifiable variables, can be optimized by directed treatment. Additionally, targeted assessments and interventions can be utilized to improve quality of life for patients with nonmodifiable risk factors.

Prenatal Ultrasound Measurement of Fetal Stomach Size Is Predictive of Postnatal Development of GERD in Isolated Cleft Lip and/or Palate.

OBJECTIVE: To determine whether prenatal ultrasound measurement of fetal stomach size, as a surrogate marker of fetal swallowing, is predictive of postnatal development of gastroesophageal reflux disease (GERD) in cases of isolated cleft lip and/or palate (CL/P). DESIGN: This is a retrospective case-control study. The outcome of interest is postnatal diagnosis of GERD in isolated CL/P. The exposure of interest is prenatal stomach size measurement by ultrasound. SETTING: The study population was selected from an academic, tertiary care center between 2003 and 2011. PATIENTS/PARTICIPANTS: Cases were neonates undergoing CL/P repair during the study period. Cases with other known structural or chromosomal abnormalities were excluded. Controls were contemporary, nondiabetic neonates that matched gestational age (within one week) to cases. Each case measurement was matched ∼1:2 with control measurement. INTERVENTIONS: None. MAIN OUTCOME MEASURE: The primary outcome was difference in mean prenatal ultrasound measurement of fetal stomach size between cases and controls. We hypothesized that patients with postnatal development of GERD would have smaller mean fetal stomach size. RESULTS: There were 32 cases including 19 patients with unilateral cleft lip and palate, 8 with unilateral cleft lip, and 4 with bilateral cleft lip and palate. Cases were noted to have smaller mean anterior-posterior and transverse fetal stomach measurements as compared to controls. This was statistically significant from 16 to 21 weeks, 25 to 27 weeks, and 28 to 36 weeks (P < .01 for all). CONCLUSIONS: Prenatal ultrasound measurement of fetal stomach size as a surrogate marker of fetal swallowing is predictive of postnatal development of GERD in isolated CL/P.

Risk and protective factors of dementia among adults with post-traumatic stress disorder: a systematic review protocol.

INTRODUCTION: Post-traumatic stress disorder (PTSD) is associated with an increased risk of dementia. Individual epidemiological studies have controlled for several confounders of the relationship between PTSD and increased dementia risk, yet particular risk factors underlying this relationship have not been determined. This systematic review protocol aims to identify risk and protective factors of dementia among adults with PTSD. METHODS AND ANALYSIS: We will conduct an electronic search of the databases: PubMed, CINAHL, PsychINFO, The Cochrane Library, Scopus and ProQuest Dissertation and Theses Global. After screening the studies, quantitative synthesis will be performed, if possible. Otherwise, a narrative synthesis will be performed. We will include randomised controlled trials and other types of research evidence including longitudinal cohort studies. Strength of evidence will be assessed using the Grading of Recommendations, Assessment, Development and Evaluations method. Examples of variables that will be extracted are: year of PTSD diagnosis, comorbid conditions, health behaviours, pharmacological treatments and year of mild cognitive impairment or dementia diagnosis. We developed this systematic review protocol according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 statement. ETHICS AND DISSEMINATION: The proposed study will not collect individual-level data and, therefore, does not require ethical approval. Results of this study will provide current evidence on risk and protective factors of dementia in adults with PTSD. Findings will be disseminated in peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42019128553.

Prospective randomized controlled trial comparing cephalad migration in robotic gynecologic surgery using egg-crate foam versus the Pink Pad®.

The objectives of the study were to compare the cephalad migration of two patient positioning pads used in robotic gynecologic surgery and to determine if any correlation exists between cephalad movement and time in Trendelenburg position or body mass index. This was a prospective randomized controlled open-label trial (Canadian Task Force classification I). Sixty women undergoing robotic-assisted laparoscopic gynecologic surgery were randomized to the Pink Pad® system or egg-crate foam pre-operatively. Patients were placed under general anesthesia and then positioned in dorsal lithotomy. The locations of the iliac crest, acromion process, and buttock were marked on the table before and after surgery to calculate cephalad migration during surgery. The primary outcome was centimeters of cephalad migration at the three anatomic landmarks. Comparing the Pink Pad® (n = 24) to the egg-crate group (n = 26) revealed similar mean cephalad migration at the iliac crest (4.8 cm vs 4.3 cm, p = 0.56) and the shoulder (4.6 cm vs 3.9 cm, p = 0.39), and less cephalad migration at the buttock (median 3.0 cm vs 2.0 cm, p = 0.041). The total time in Trendelenburg was not correlated with cephalad migration at any anatomic landmark. Body mass index was positively correlated with cephalad migration only at the iliac crest (p = 0.032) regardless of pad type. The egg-crate foam resulted in less cephalad migration at all anatomic sites and significantly less migration at the buttocks compared to the Pink Pad®. This suggests that the less-costly egg-crate foam is noninferior to the Pink Pad® system and trends at superiority.

Sanctioning of Illegal and Dangerous Ruck Cleanouts During the 2018 Super Rugby Competition.

Rugby is a high contact sport that results in many injuries. The majority of injuries at senior elite levels result from contact phases during match-play. It is estimated that 10% of all match injuries are associated with the ruck in professional and community rugby. Surveillance of legal and illegal ruck cleanouts and the sanctions imposed by the on-field referees will help identify whether referees are actually enforcing the law according to the laws of the game, which will consequently contribute to the creation and implementation of further injury prevention strategies. Players should play the game in accordance with the laws of the game and be mindful of their own safety and that of others. Coaches and trainers of the game have the responsibility to ensure that players are prepared in a manner that comply with the World Rugby (WR) laws of the game and safe practices. Laws and law amendments are fundamental to the development of sport and introduced for a variety of reasons. The aim of this study was to investigate the rate of sanctioning of illegal and dangerous ruck cleanouts during the 2018 Super Rugby competition by using Nacsport Basic+ video software; 120 round robin matches from the 2018 Super Rugby competition were coded and analyzed. The analysis of the intra reliability showed an almost perfect (>0.95) agreement between all the performance indicators. In total, 22,281 ruck cleanouts were coded of which 9% (n = 2111) were illegal ruck cleanouts and 93% were not sanctioned by the referees; 57% (1087 out of 1953) of the illegal ruck cleanouts not sanctioned by the referees were deemed dangerous. The majority of dangerous illegal ruck cleanouts not sanctioned by the referees were "shoulder charge" (88%, n = 280), "neck roll" (86%, n = 100), and "contact above the shoulder" (81%, n = 201). To aid injury prevention efforts in rugby, future research studies should investigate why on-field referees are not sanctioning all illegal and dangerous ruck cleanouts according to WR Laws of the Game.

Traumatic brain injury causes selective, CD74-dependent peripheral lymphocyte activation that exacerbates neurodegeneration.

INTRODUCTION: Traumatic brain injury (TBI), a significant cause of death and disability, causes, as in any injury, an acute, innate immune response. A key component in the transition between innate and adaptive immunity is the processing and presentation of antigen by professional antigen presenting cells (APCs). Whether an adaptive immune response to brain injury is beneficial or detrimental is not known. Current efforts to understand the contribution of the immune system after TBI have focused on neuroinflammation and brain-infiltrating immune cells. Here, we characterize and target TBI-induced expansion of peripheral immune cells that may act as potential APCs. Because MHC Class II-associated invariant peptide (CLIP) is important for antigen processing and presentation, we engineered a competitive antagonist (CAP) for CLIP, and tested the hypothesis that peptide competition could reverse or prevent neurodegeneration after TBI. RESULTS: We show that after fluid percussion injury (FPI), peripheral splenic lymphocytes, including CD4+ and CD8+ T cells, regulatory T cells (Tregs), and γδ T cells, are increased in number within 24 hours after FPI. These increases were reversed by CAP treatment and this antagonism of CLIP also reduced neuroinflammation and neurodegeneration after TBI. Using a mouse deficient for the precursor of CLIP, CD74, we observed decreased peripheral lymphocyte activation, decreased neurodegeneration, and a significantly smaller lesion size following TBI. CONCLUSION: Taken together, the data support the hypothesis that neurodegeneration following TBI is dependent upon antigen processing and presentation that requires CD74.

Intrauterine growth restriction and prematurity influence regulatory T cell development in newborns.

PURPOSE: The aim of this study was to determine the relationship of birth weight and gestational age with regulatory T cells (Tregs) in cord blood of human newborns. METHODS: Cord blood mononuclear cells (CBMCs) of 210 newborns were analyzed using flow cytometry to identify Tregs (CD3(+), CD4(+), CD25(high), FoxP3(high)) and measure FoxP3 mean fluorescence intensity (MFI). Suppressive index (SI) was calculated as FoxP3 MFI per Treg. RESULTS: Mode of delivery had no significant effect on Tregs at birth. Term babies with growth restriction had fewer Tregs than their appropriate weight counterparts but equivalent SI. Preterm babies had higher percentages of Tregs, but lower SI than term controls. SI steadily increased through gestation. CONCLUSIONS: Intrauterine growth restriction is correlated with fewer circulating Tregs and prematurity with decreased functionality of Tregs compared to term appropriate weight infants. This may have implications in diseases such as necrotizing enterocolitis that disproportionately affect premature and lower birth weight infants.
