Impact of Socioeconomic Factors on Time to Surgery for Distal Radius Fractures.

Background: Delay in care secondary to socioeconomic status (SES) and demographic factors represents an area for potential improvement. Reducing time to surgery in distal radius fracture (DRF) fixation may improve outcomes while reducing cost. The purpose of this study is to investigate the effect of SES on time to surgery in our study population. Methods: Patients undergoing outpatient DRF surgery within an academic healthcare system during a 4-year period were reviewed. Time to surgery and demographic factors were analyzed. The US Census Bureau was used to determine median household income (MHI) for a patient's ZIP code; patients were stratified into three groups based on MHI. Results: A total of 413 patients met inclusion criteria. SES (14.7 d in the low-SES group, 14.0 d in the mid-SES group, and 11.1 d in the high-SES group, P = 0.00063), insurance (11.7 d for insured versus 16.3 d for Medicaid/uninsured, P < 0.0001), race (non-White group: 15.2 d versus White group: 10.9 d, P < 0.0001), and treatment facility (16.2 d at county hospital versus 10.9 d at university hospital, P < 0.0001) were associated with time to surgery in univariate analysis. Multivariate analysis found that only treatment facility was associated with time to surgery. Conclusions: Non-White, uninsured/Medicaid individuals residing in low-SES areas may be more likely to receive care at a safety-net facility and are at greatest risk for delay in time to surgery. Measures aimed to reduce barriers to care, increase healthcare coverage, and improve patient education should be initiated to mitigate these disparities.

Pain, function and quality of life are impaired in adults undergoing periacetabular osteotomy (PAO) for hip dysplasia: a systematic review and meta-analysis.

BACKGROUND: Hip dysplasia is a common condition in active adults with hip pain that can lead to joint degeneration. Periacetabular osteotomy (PAO) is a common surgical treatment for hip dysplasia. The effect of this surgery on pain, function and quality of life (QOL) has not been systematically analysed. PURPOSE: In adults with hip dysplasia: (1) evaluate differences in pain, function and QOL in those undergoing PAO and healthy controls; (2) evaluate pre- to post-PAO changes in pain, function and QOL; (3) evaluate differences in pain, function and QOL in those with mild versus severe dysplasia, undergoing PAO; and (4) evaluate differences in pain, function and QOL in those having primary PAO versus those with previous hip arthroscopy. METHODS: A comprehensive, reproducible search strategy was performed on 5 different databases. We included studies that assessed pain, function and QOL in adults undergoing PAO for hip dysplasia, using hip-specific patient reported outcomes measures. RESULTS: From 5017 titles and abstracts screened, 62 studies were included. Meta-analysis showed PAO patients had worse outcomes pre- and post-PAO compared to healthy participants. Specifically, pain (standardised mean difference [SMD] 95% confidence interval [CI]): -4.05; -4.78 to -3.32), function (-2.81; -3.89 to -1.74), and QOL (-4.10; -4.43 to -3.77) were significantly poorer preoperatively.Meta-analysis found patients experienced improvements following PAO. Pain improved from pre-surgery to 1-year (standardised paired difference [SPD] 1.35; 95% CI, 1.02-1.67) and 2 years postoperatively (1.35; 1.16-1.54). For function, the activities of daily living scores at 1 year (1.22; 1.09-1.35) and 2 years (1.06; 0.9-1.22) and QOL at 1 year (1.36; 1.22-1.5) and 2 years (1.3; 1.1-1.5) all improved. No difference was found between patients undergoing PAO with mild versus severe dysplasia. CONCLUSIONS: Before undergoing PAO surgery, adults with hip dysplasia have worse levels of pain, function and QOL compared to healthy participants. These levels improve following PAO, but do not reach the same level as their healthy participants. REGISTRATION: PROSPERO (CRD42020144748).

Environmental and climate variability drive population size of annual penaeid shrimp in a large lagoonal estuary.

Species with short life spans frequently show a close relationship between population abundance and environmental variation making these organisms potential indicator species of climatic variability. White (Penaeus setiferus), brown (P. aztecus), and pink (P. duorarum) penaeid shrimp typically have an annual life history and are of enormous ecological, cultural, and economic value to the southeastern United States and Gulf of Mexico. Within North Carolina, all three species rely on the Pamlico Sound, a large estuarine system that straddles Cape Hatteras, one of the most significant climate and biogeographic breaks in the world, as a nursery area. These characteristics make penaeid species within the Pamlico Sound a critical species-habitat complex for assessing climate impacts on fisheries. However, a comprehensive analysis of the influence of the environmental conditions that influence penaeid shrimp populations has been lacking in North Carolina. In this study, we used more than 30 years of data from two fishery-independent trawl surveys in the Pamlico Sound to examine the spatial distribution and abundance of adult brown, white, and pink shrimp and the environmental drivers associated with adult shrimp abundance and juvenile brown shrimp recruitment using numerical models. Brown shrimp recruitment models demonstrate that years with higher temperature, salinity, offshore windstress, and North Atlantic Oscillation phase predict increased abundance of juveniles. Additionally, models predicting adult brown, white, and pink shrimp abundance illustrate the importance of winter temperatures, windstress, salinity, the North Atlantic Oscillation index, and the abundance of spawning adult populations from the previous year on shrimp abundance. Our findings show a high degree of variability in shrimp abundance is explained by climate and environmental variation and indicate the importance of understanding these relationships in order to predict the impact of climate variability within ecosystems and develop climate-based adaptive management strategies for marine populations.

Physical impairments in Adults with Developmental Dysplasia of the Hip (DDH) undergoing Periacetabular osteotomy (PAO): A Systematic Review and Meta-Analysis.

Background: Developmental dysplasia of the hip (DDH) is a condition associated with hip pain and impairments. Periacetabular osteotomy (PAO) is a common surgical treatment for DDH. Outcomes following PAO have historically been based on radiology or patient reported outcomes, and not physical impairments. Objective: To investigate differences in physical impairments in adults with DDH undergoing PAO compared with asymptomatic participants, and to investigate pre- to post-PAO changes in physical impairments. Design: Systematic review with meta-analysis. Methods: A literature search was performed in five databases (MEDLINE, CINAHL, EMBASE, Sports Discuss, and PsychINFO), using the PRISMA checklist. Studies were considered eligible if patients were aged 15 years and older, treated with PAO for DDH and if they included a physical impairment outcome measure. Two independent reviewers performed data extraction and assessed methodological quality, using a modified version of the Downs and Black checklist. Results: Of 5,017 studies, 24 studies were included with 2190 patients. The methodological quality scores ranged from 39% to 88%. With low level of evidence, meta-analysis showed 58% of patients had a positive anterior impingement test (95%CI: 39-76%), prior to PAO and one to three years after PAO. Five years after PAO, the proportion fell to 17% (95%CI: 11-24%). Prior to PAO, patients with DDH walked with a lower peak hip extension angle, compared to asymptomatic participants (SMD 0.65 (95%CI 0.21-1.10). Best evidence synthesis of non-pooled data showed limited evidence of increased walking velocity, stride length and improved hip flexion and extension moment 18-months post-PAO compared to pre-op. Cadence, hip abduction and hip flexion strength did not change. Conclusion: Most patients with DDH have a positive hip impingement test, pre-PAO. Compared to asymptomatic participants, patients with DDH demonstrate physical impairments during walking which appear to improve after surgery. Hip abduction and flexion strength did not change pre- to post-PAO. Level of Evidence: 1b.

Seroprevalence of SARS-CoV-2-Specific IgG Antibodies Among Adults Living in Connecticut: Post-Infection Prevalence (PIP) Study.

BACKGROUND: A seroprevalence study can estimate the percentage of people with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the general population; however, most existing reports have used a convenience sample, which may bias their estimates. METHODS: We sought a representative sample of Connecticut residents, ages ≥18 years and residing in noncongregate settings, who completed a survey between June 4 and June 23, 2020, and underwent serology testing for SARS-CoV-2-specific immunoglobulin G (IgG) antibodies between June 10 and July 29, 2020. We also oversampled non-Hispanic black and Hispanic subpopulations. We estimated the seroprevalence of SARS-CoV-2-specific IgG antibodies and the prevalence of symptomatic illness and self-reported adherence to risk-mitigation behaviors among this population. RESULTS: Of the 567 respondents (mean age 50 [± 17] years; 53% women; 75% non-Hispanic white individuals) included at the state level, 23 respondents tested positive for SARS-CoV-2-specific antibodies, resulting in weighted seroprevalence of 4.0 (90% confidence interval [CI] 2.0-6.0). The weighted seroprevalence for the oversampled non-Hispanic black and Hispanic populations was 6.4% (90% CI 0.9-11.9) and 19.9% (90% CI 13.2-26.6), respectively. The majority of respondents at the state level reported following risk-mitigation behaviors: 73% avoided public places, 75% avoided gatherings of families or friends, and 97% wore a facemask, at least part of the time. CONCLUSIONS: These estimates indicate that the vast majority of people in Connecticut lack antibodies against SARS-CoV-2, and there is variation by race and ethnicity. There is a need for continued adherence to risk-mitigation behaviors among Connecticut residents to prevent resurgence of COVID-19 in this region.

Nutrition Policies, Practices, and Environments in Low-Income Georgia Elementary Schools, United States, 2015-2017.

BACKGROUND: A nutritious diet can prevent obesity and chronic disease and improve academic performance, yet many children have energy-dense, nutrient-poor diets. The objective of this study was to assess nutrition policies, practices, and environments in Georgia Supplemental Nutrition Assistance Program Education (SNAP-Ed) elementary schools and compare them across school-level demographic characteristics. METHODS: We distributed a cross-sectional online survey to administrators, grade level chairs, and nutrition managers from 113 Georgia SNAP-Ed elementary schools during 2015-2017. Logistic regression, one-way ANOVA, and Tukey's tests were performed to assess differences by free and reduced-price lunch eligibility and percentage black. Fisher's exact and Rao-Scott chi-square tests were performed to assess differences by school size and geography. RESULTS: The majority of schools established wellness policies and committees, provided nutrition education, and offered fresh fruits and/or vegetables daily. Fewer schools had policies limiting sugar-sweetened foods within classrooms or had established a school garden. There were minimal significant differences in survey responses across school-level demographics. CONCLUSIONS: Georgia SNAP-Ed elementary schools are providing healthy nutrition settings for their students in a number of areas, and can further improve by establishing more comprehensive wellness policies, a committee to enforce them, and engaging children in hands-on nutrition education activities.

Return to Play After PRP and Rehabilitation of 3 Elite Ice Hockey Players With Ulnar Collateral Ligament Injuries of the Elbow.

BACKGROUND: Ulnar collateral ligament (UCL) injury is a well-described etiology of pain and decreased performance for the overhead athlete. Despite a growing volume of literature regarding the treatment of these injuries for overhead athletes, there is a paucity of such data regarding stickhandling collision sport athletes, such as ice hockey players. PURPOSE/HYPOTHESIS: The purpose of this study was to characterize this injury among 3 elite ice hockey players and to describe the ability of these athletes to return to play, as well as to review the unique sport-specific implications of this injury, evaluation, nonsurgical management, and considerations for return to play. The authors hypothesized that elite ice hockey players will be able to return to play at the same level following nonoperative treatment of UCL injury. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Data from 3 elite professional ice hockey players who sustained a high-grade injury to the UCL were retrospectively reviewed. All athletes underwent 2 autologous conditioned plasma injections as part of their treatment and were evaluated with ultrasonography and magnetic resonance imaging. RESULTS: Three consecutive elite ice hockey players were included in this study, and no patients were excluded. Players were cleared to full return to play at a mean 36 days postinjury. Follow-up examination at this time point demonstrated full range of motion of the elbow for all athletes, without tenderness to palpation over the UCL, including no tenderness over the humeral insertion site. Stability examination improved as well, demonstrating a soft to moderate endpoint with valgus stress, although this was not symmetric to the contralateral side. All athletes were able to continue to play at the same level of competition as before the injury occurred, without any complaints. No players had repeat injury during the same or following seasons. CONCLUSION: The authors present 3 elite-level ice hockey players who sustained a high-grade injury to the UCL. Successful return to play was possible after nonoperative treatment with injection of autologous conditioned plasma at a mean 36 days following injury. Athletes who injure either the top or bottom hand can return to play at the same elite level following this injury.

Development and Psychometric Evaluation of the Child Neglect Questionnaire.

Neglect poses a significant risk for children throughout their development and is often linked with serious consequences that reach into adulthood. The Child Neglect Questionnaire (CNQ) fills existing gaps by incorporating multiple perspectives from both parents and the child, as well as measuring the complex phenomenon of neglect multidimensionally. Furthermore, this measure addresses the need for an instrument specifically developed for late childhood (ages 10-12), as much of the extant evidence and corresponding measures focus on young children and their mothers. A panel of three psychologists, using Cicchetti's model of child neglect as a theoretical guide, began by selecting items from an existing database. Results of exploratory and confirmatory factor analyses and item response theory demonstrated the unidimensionality of physical, emotional, educational, and supervision neglect as well as a second-order construct of child neglect. Analyses controlling for risk status due to father's substance use disorder, socioeconomic status, and child's ethnicity demonstrated that father's and mother's (parental) neglect, particularly in the child's versions, had sound concurrent and predictive validity. Concurrently, at age 10-12, the child's version of both parents' neglect correlated with their parenting behaviors evaluated by other available measures. Prospectively, from 10-12 years of age to 11-13 years of age, parental neglect predicted child's drug use frequency with coexisting psychological dysregulation, psychiatric symptoms, antisocial behavior, non-normative sexual behavior, involvement with deviant peers and leisure activities thus demonstrating sound predictive validity. Also, internal consistency and inter-rater reliability were excellent. The CNQ, particularly the child's version, may thus be useful for detecting children at high risk for parental neglect.

Youth mentoring: what is it and what do we know?

This article serves as a review of the mentoring literature. Specifically, it seeks to review discussions on the issues, particularly the difficulties of defining the term mentor. Next there is an examination of any empirical evidence of possible benefits resulting from mentoring relationships. Lastly, the article explores the mentoring relationship in an effort to determine which, if any, specific characteristics may impact any positive outcomes.

Lactoferrin: Antimicrobial activity and therapeutic potential.

Lactoferrin is a highly conserved protein from an evolutionary perspective, with a wide range of roles related to protection from infection and promotion of nutritional status. Infection, malnutrition and intestinal pathologies are key inter-related problems, represent important threats to survival and are associated with adverse long-term health outcomes after preterm birth. Lactoferrin is available as a commercial extract from bovine milk and offers potential as a therapeutic intervention for preterm infants modulating infections and intestinal pathologies. In this review we explore the structure, direct antimicrobial effects, modification of host immune function and gastrointestinal effects of lactoferrin. Current trial data are reviewed, and research priorities and challenges identified and discussed.

Improving outcomes for at-risk youth: findings from the Prodigy Cultural Arts Program.

Through this study the authors evaluate the Prodigy Cultural Arts Program, an early prevention program for adjudicated youth. A quasi experimental pre- and posttest was conducted. A significant reduction in mental health symptoms (particularly for females) and behavioral dysregulation (particularly for males), and increases in academic performance and family functioning were found. There was also a relationship between decreased mental health symptomology and perceived academic performance. The Prodigy Cultural Arts Program appears to be successful in intervening with youth who present challenges to the juvenile justice system due to the complexity of their mental health symptoms, behavioral regulation difficulties, and/or gender.

Timing of pulp extirpation for replanted avulsed teeth.

DATA SOURCES: A search was performed (April 2004) across four databases, namely Ovid Medline, Cochrane Library, PubMed and Web of Science, relevant to the proposed PICO ( Patient or problem, Intervention, Comparison, Outcome) question: (P) for a replanted avulsed permanent tooth, (I) is early pulp extirpation within 10-14 days of replantation, (C) compared with delayed pulp extirpation, (O) associated an increased likelihood of successful periodontal healing after tooth replantation. Only articles published in the English language were considered. STUDY SELECTION: Relevant titles were selected for abstract assessment (N = 628), and then 84 papers were selected for examination. DATA EXTRACTION AND SYNTHESIS: A quality assessment was made of relevant publications: only six papers met the inclusion criteria (making a total of 236 teeth). RESULTS: Meta-analyses found a statistically significant association between pulp extirpation performed after 14 days and the development of inflammatory resorption. Pulp extirpation within 10 days of replantation was not significantly associated with a decreased likelihood of developing inflammatory resorption. There is no significant difference in pulp extirpation times for functional healing, acceptable healing without progressive resorption, or the development of replacement resorption. CONCLUSIONS: There is clinical evidence for an association between pulp extirpation performed after 14 days following replantation and the development of inflammatory resorption. This investigation supports the current clinical guidelines for pulp extirpation within 10-14 days of replantation.

Adolescent childbearing in Nicaragua: a quantitative assessment of associated factors.

CONTEXT: Nicaragua has one of the highest adolescent fertility rates in the world, but little is known about why approximately half of Nicaraguan women give birth before age 20. METHODS: Data from the 2001 Nicaragua Demographic and Health Survey were used to examine the sexual and reproductive behavior of 3,142 females aged 15-19. Age at sexual debut and age at first birth were assessed using life table analysis, and the impacts of various factors on these measures were then examined in Cox proportional hazard models. Among sexually active females, current use of modern contraceptives was examined using logistic regression analysis. RESULTS: In Cox models, rural residence, rising levels of education and greater wealth were associated with older age at sexual debut (hazard ratios, 0.8, 0.5 and 0.9, respectively). When these factors were accounted for in multivariate analysis, age at first birth was positively associated with age at first sex: Having had first sex before age 15 was associated with an increased risk of having an earlier first birth (1.7-2.4), whereas having first had sex at age 16 or later was associated with a decreased risk (0.2-0.7). Among sexually active females, current use of a modern method was positively associated with being married or in a stable union and with having given birth (5.8 and 4.5, respectively), and negatively associated with lacking health care autonomy and wanting a baby within two years (0.4 and 0.6, respectively). CONCLUSIONS: Interventions that improve young women's education and economic opportunities might help them delay both sexual debut and childbearing, and efforts are also needed to facilitate their access to contraceptives, particularly for unmarried women.

Elevated brain scyllo-inositol concentrations in patients with Alzheimer's disease.

in vivo (1)H MRS reveals reduced N-acetylaspartate (NAA) and elevated myo-inositol (mI) in patients with mild Alzheimer's disease (AD) and patients with amnestic mild cognitive impairment (MCI). We are unaware of studies that have documented abnormal scyllo-inositol (sI) levels in patients with AD or patients with MCI, although a previous MRS study in older adults has indicated that sI is a peak of interest to measure in AD. Fifteen patients with mild AD, 26 patients with amnestic MCI, and 19 healthy older adults were recruited to this study. All underwent (1)H MRS of the posterior cingulate gyrus of the brain using a 3 T MRI scanner. Increases in the sI/creatine (Cr) ratio were observed in patients with mild AD (P < 0.05). The mI/Cr ratio was raised in patients with mild AD (P < 0.01) and MCI (P < 0.05). Reduced NAA/Cr was detected in patients with mild AD (P < 0.05). The sI/Cr ratio correlated negatively (r = -0.60, P < 0.05) with a measure of clock drawing in patients with mild AD, indicating that impaired cognitive ability in AD is associated with higher concentrations of sI/Cr. In vivo measurement of sI/Cr in the posterior cingulate gyrus of patients with mild AD revealed increases compared with cognitively healthy older adults. Further research on the mechanisms of sI increase in AD is needed. Future studies on the longitudinal course of sI/Cr in MCI and AD appear warranted.
