ABSTRACT
Healthy dietary practices are highly influenced by social norms, the widely-held expectations about the behaviors that are appropriate or typical within a given group. However, many nutrition programs designed to reduce women's undernutrition in low- and middle-income countries do not address the influence of social and gender norms in their interventions, and therefore, there is limited information about how norms-responsive interventions have been designed and implemented. The objective of this scoping review was to identify and describe social and behavioral change interventions designed to improve women's dietary practices and nutritional intake that integrate the influence of social and gender norms. We systematically searched 4 databases (Scopus, Web of Science, PubMed, and CINAHL) for peer-reviewed articles describing design, implementation, and/or assessment of nutrition interventions in low- or middle-income countries. Results are reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Our review identified 27 articles from 25 projects or research studies that addressed social or gender norms related to women's dietary practices. The majority focused on the pregnancy and lactation periods, and a few aimed to reach all women of reproductive age. Interventions most often endeavored to shift norms through multiple activities, channels, and platforms, aiming to reach not only the primary participants but also influencers and reference groups. Intervention approaches ranged from home visits and support groups to engage influential family members to community-level outreach with opinion leaders such as religious leaders, health care workers, and peer change agents. Most interventions were delivered through the health sector or were community-based, with some nutrition-sensitive agriculture interventions. There is increasing, although still limited, integration of social and gender norms perspectives in the design, implementation, and assessment of interventions to improve women's diets. This comprehensive review summarizes influential norms and intervention approaches, an important step toward enhancing the effectiveness of social and behavioral change interventions by addressing nutrition-relevant norms. This study was registered at Open Science Framework as JSBF7.
ABSTRACT
Carbon neutral or negative mining can potentially be achieved by integrating carbon mineralization processes into the mine design, operations, and closure plans. Brucite [Mg(OH)2] is a highly reactive mineral present in some ultramafic mine tailings with the potential to be rapidly carbonated and can contain significant amounts of ferrous iron [Fe(II)] substituted for Mg; however, the influence of this substitution on carbon mineralization reaction products and efficiency has not been thoroughly constrained. To better assess the efficiency of carbon storage in brucite-bearing tailings, we performed carbonation experiments using synthetic Fe(II)-substituted brucite (0, 6, 23, and 44 mol % Fe) slurries in oxic and anoxic conditions with 10% CO2. Additionally, the carbonation process was evaluated using different background electrolytes (NaCl, Na2SO4, and Na4SiO4). Our results indicate that carbonation efficiency decreases with increasing Fe(II) substitution. In oxic conditions, precipitation of ferrihydrite [Fe10IIIO14(OH)2] and layered double hydroxides {e.g., pyroaurite [Mg6Fe2III(OH)16CO3·4H2O]} limited carbonation efficiency. Carbonation in anoxic environments led to the formation of Fe(II)-substituted nesquehonite (MgCO3·3H2O) and dypingite [Mg5(CO3)4(OH)2·â¼5H2O], as well as chukanovite [Fe2IICO3(OH)2] in the case of 23 and 44 mol % Fe(II)-brucite carbonation. Carbonation efficiencies were consistent between chloride- and sulfate-rich solutions but declined in the presence of dissolved Si due to the formation of amorphous SiO2·nH2O and Fe-Mg silicates. Overall, our results indicate that carbonation efficiency and the long-term fate of stored CO2 may depend on the amount of substituted Fe(II) in both feedstock minerals and carbonate products.

The simultaneous circulation of seasonal influenza virus and SARS-CoV-2 variants will likely pose unique challenges to public health during the future influenza seasons. Persons who are undergoing treatment in healthcare facilities may be particularly at risk. It is important for healthcare personnel to protect themselves and patients by receiving vaccines. The purpose of this study is to assess coverage of the seasonal influenza vaccine and COVID-19 monovalent booster among healthcare personnel working at acute care hospitals in the United States during the 2021-22 influenza season and to examine the demographic and facility characteristics associated with coverage. A total of 3260 acute care hospitals with over 7 million healthcare personnel reported vaccination data to National Healthcare Safety Network (NHSN) during the 2021-22 influenza season. Two separate negative binomial mixed models were developed to explore the factors associated with seasonal influenza coverage and COVID-19 monovalent booster coverage. At the end of the 2021-2022 influenza season, the overall pooled mean seasonal influenza coverage was 80.3%, and the pooled mean COVID-19 booster coverage was 39.5%. Several demographic and facility-level factors, such as employee type, facility ownership, and geographic region, were significantly associated with vaccination against influenza and COVID-19 among healthcare personnel working in acute care hospitals. Our findings highlight the need to increase the uptake of vaccination among healthcare personnel, particularly non-employees, those working in for-profit and non-medical school-affiliated facilities, and those residing in the South.

Background: Comprehensive and transparent reporting of clinical trial activity is important. The Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 and Consolidated Standards of Reporting Trials (CONSORT) 2010 statements define the items to be reported in clinical trial protocols and randomized controlled trials, respectively. The aim of this methodological review was to assess the reporting quality of adult neuro-oncology trial protocols and trial result articles. Methods: Adult primary and secondary brain tumor phase 3 trial protocols and result articles published after the introduction of the SPIRIT 2013 statement, were identified through searches of 4 electronic bibliographic databases. Following extraction of baseline demographic data, the reporting quality of independently included trial protocols and result articles was assessed against the SPIRIT and CONSORT statements respectively. The CONSORT-A checklist, an extension of the CONSORT 2010 statement, was used to specifically assess the abstract accompanying the trial results article. Percentage adherence (standard deviation [SD]) was calculated for each article. Results: Seven trial protocols, and 36 trial result articles were included. Mean adherence of trial protocols to the SPIRIT statement was 79.4% (SD: 0.11). Mean adherence of trial abstracts to CONSORT-A was 75.3% (SD: 0.12) and trial result articles to CONSORT was 74.5% (SD: 0.10). Conclusion: The reporting quality of adult neuro-oncology trial protocols and trial result articles requires improvement to ensure comprehensive and transparent communication of planned neuro-oncology clinical trials and results within the literature. Raising awareness by clinical triallists and implementing mandatory evidence of proof of adherence by journals should improve reporting quality.
ABSTRACT
The methyl-lysine readers plant homeodomain finger protein 20 (PHF20) and its homolog PHF20-like protein 1 (PHF20L1) are known components of the nonspecific lethal (NSL) complex that regulates gene expression through its histone acetyltransferase activity. In the current model, both PHF homologs coexist in the same NSL complex, although this was not formally tested; nor have the functions of PHF20 and PHF20L1 regarding NSL complex integrity and transcriptional regulation been investigated. Here, we perform an in-depth biochemical and functional characterization of PHF20 and PHF20L1 in the context of the NSL complex. Using mass spectrometry, genome-wide chromatin analysis, and protein-domain mapping, we identify the existence of two distinct NSL complexes that exclusively contain either PHF20 or PHF20L1. We show that the C-terminal domains of PHF20 and PHF20L1 are essential for complex formation with NSL, and the Tudor 2 domains are required for chromatin binding. The genome-wide chromatin landscape of PHF20-PHF20L1 shows that these proteins bind mostly to the same genomic regions, at promoters of highly expressed/housekeeping genes. Yet, deletion of PHF20 and PHF20L1 does not abrogate gene expression or impact the recruitment of the NSL complex to those target gene promoters, suggesting the existence of an alternative mechanism that compensates for the transcription of genes whose sustained expression is important for critical cellular functions. This work shifts the current paradigm and lays the foundation for studies on the differential roles of PHF20 and PHF20L1 in regulating NSL complex activity in physiological and diseases states.

Background: Heart failure with preserved ejection fraction represents a major unmet clinical need with limited treatment options. Recent device therapies under investigation have focused on decompression of the left atrium through an implantable interatrial shunt. Although these devices have shown favorable safety and efficacy signals, an implant is required to maintain shunt patency, which may increase the patient risk profile and complicate subsequent interventions requiring transseptal access. Methods: The Alleviant System is a no-implant approach to creating an interatrial shunt using radiofrequency energy to securely capture, excise, and extract a precise disk of tissue from the interatrial septum. Acute preclinical studies in healthy swine (n = 5) demonstrated the feasibility of the Alleviant System to repeatably create a 7 mm interatrial orifice with minimal collateral thermal effect and minimal platelet and fibrin deposition observed histologically. Results: Chronic animal studies (n = 9) were carried out to 30- and 60-day time points and exhibited sustained shunt patency with histology demonstrating completely healed margins, endothelialization, and no trauma to adjacent atrial tissue. Preliminary clinical safety and feasibility were validated in a first-in-human study in patients with heart failure with preserved ejection fraction (n = 15). All patients demonstrated shunt patency by transesophageal echocardiographic imaging at 1, 3, and 6 months, as well as cardiac computed tomography imaging at 6-month follow-up timepoints. Conclusions: Combined, these data support the safety and feasibility of a novel no-implant approach to creating an interatrial shunt using the Alleviant System. Continued follow-up and subsequent clinical studies are currently ongoing.
ABSTRACT
ABSTRACT: Palisaded neutrophilic and granulomatous dermatitis (PNGD) represents a cutaneous histopathologic reaction spectrum associated with several underlying disorders. Few cases of PNGD have been associated with chronic myelomonocytic leukemia (CMML), a malignant hematopoietic disorder with features in between those of a myeloproliferative neoplasm and myelodysplastic syndrome. We present a patient with a generalized papular skin reaction involving the neck, chest, and shoulders with histomorphological features on the spectrum of PNGD. Subsequent laboratory workup demonstrated a persistent mild monocytosis, raising concern for CMML. The diagnosis was ultimately confirmed with a bone marrow biopsy and associated mutational analysis through next-generation sequencing which identified deleterious variants in SRSF2, IDH2, and ASXL1. The findings in this case strengthen the previously made association between PNGD and SRSF2-mutated CMML and may help better define a unique recognizable clinical-histopathological-molecular subtype for dermatopathologists.

OBJECTIVE: The objective of this study was to determine the accuracy of fast brain magnetic resonance imaging (MRI) in the detection of intra- and extra-axial intracranial hemorrhage compared with standard-of-care computed tomography (CT) or MRI in pediatric patients. Unlike previous studies, we did not focus exclusively on patients with head trauma. We evaluated the fast brain MRI findings in a general pediatric population referred for indications other than evaluation of ventricular size. METHODS: We retrospectively reviewed 48 pediatric patients with indications other than hydrocephalus and shunt follow-up, who underwent a standard head CT or standard MRI within 15 days of the fast brain MRI. All fast brain MRI scans included half-Fourier acquisition with single-shot turbo spin echo (HASTE) sequences in the axial, coronal, and sagittal plane. Two neuroradiologists blinded to patient information and study indications reviewed the fast brain MRI studies independently and then concurrently. RESULTS: A total of 48 patients met the inclusion and exclusion criteria. The median and mean time interval between the standard and fast imaging were 2 and 3.9 days, respectively. The sensitivity and specificity of fast brain MRI to detect intraparenchymal hemorrhage were 100% and 97%, respectively. The sensitivity and specificity of fast brain MRI in the detection of extra-axial hemorrhage (subdural and/or epidural) were 86% and 96%, respectively. The sensitivity and specificity of fast brain MRI were, respectively, 10% and 100% for subarachnoid hemorrhage, 50% and 100% for intraventricular hemorrhage, and 47% and 97% for skull fracture, respectively. CONCLUSIONS: Our results show that fast brain MRI with HASTE sequence is as sensitive as CT and standard MRI in the detection of intra-axial hemorrhage and has moderate sensitivity in the detection of extra-axial hemorrhage. Our preliminary results show that T2-weighted HASTE imaging may be suitable for the follow-up of intraparenchymal and extra-axial (subdural and/or epidural) hemorrhages.

Centruroides is a common genus of bark scorpions in the United States with at least 21 species considered to be medically important, including the closely related Centruroides exilicauda and Centruroides sculpturatus. Stings from C exilicauda and C sculpturatus have been shown to cause fatality in children more often than in adults. More severe complications are caused by the neurotoxin released by Centruroides stings. Most stings can be managed at home, but for those patients who require treatment, antivenin has been shown to decrease time to symptom abatement.

BACKGROUND: Atopic dermatitis (AD) is a common, chronic type 2 inflammatory skin disease, typically starting in infancy, with increased risk for subsequent extracutaneous atopic morbidities. Dupilumab is the first biologic agent targeting type 2 inflammation approved by the U.S. Food and Drug Administration (USFDA); it was licensed in 2017 for adults with moderate to severe AD and 2 years later for adolescents. Systemic treatment for pediatric AD remains a significant unmet medical need. OBJECTIVE: To analyze off-label use of dupilumab in children with AD. METHODS: Multicenter retrospective review that evaluated children who were prescribed dupilumab for moderate to severe AD. RESULTS: One hundred eleven of 124 patients (89.5%) gained access to dupilumab after a mean of 9 weeks. The dosing range was 4 to 15.5 mg/kg for the loading dose and 2.0 to 15.3 mg/kg every other week for maintenance. The range was widest for 6- to 11-year-olds and was related to use of either full or half of adult dosing. Associated morbidities, treatment response, and adverse events were comparable to those in previous adolescent and adult trials. LIMITATIONS: The retrospective design of the study limited uniform data collection. CONCLUSION: Access to dupilumab was achievable for the majority of children after a mean 9-week delay because of insurance payment denial. This review supports dupilumab response and tolerability in children. Optimal dosing for patients younger than 12 years has not been defined. Availability of the drug in 2 different concentrations is an important safety issue.

PURPOSE: To evaluate the impact of a medication to bedside delivery (meds-to-beds) service on hospital reutilization in an adult population. METHODS: A retrospective, single-center, observational cohort study was conducted within a regional academic medical center from January 2017 to July 2017. Adult patients discharged from an internal medicine unit with at least one maintenance medication were evaluated. The primary outcome was the incidence of 30-day hospital reutilization between two groups: discharged patients who received meds-to-beds versus those who did not. Additionally, the incidence of 30-day hospital reutilization between the two groups was compared within predefined subgroup patient populations: polypharmacy, high-risk medication use, and patients with a principal discharge diagnosis meeting the criteria set by the Centers for Medicare and Medicaid Services 30-day risk standardized readmission measures. RESULTS: A total of 600 patients were included in the study (300 patients in the meds-to-beds group and 300 patients in the control group). The 30-day hospital reutilization (emergency department visits and/or hospital readmissions) related to the index visit was lower in the meds-to-beds group, but the difference was not statistically significant between the two groups (8.0% in the meds-to-beds group versus 10.0% in the control group; odds ratio, 0.78; 95% confidence interval, 0.45-1.37). There was no significant difference in the 30-day hospital reutilization related to the index visit between the control and meds-to-beds groups within the three subgroups analyzed. CONCLUSION: There was no difference in 30-day hospital reutilization related to the index visit with the implementation of meds-to-beds service in the absence of other transitions-of-care interventions.

INTRODUCTION: Obesity and overweight, defined as body mass index (BMI) of 30.0 and above or 25.0-29.9, respectively, are of significant concern to the military population, due to their associated comorbidities and potential for impaired readiness. In 2016, the US Army reported a prevalence of 17.3% obesity and 52.9% overweight among soldiers, despite both physical demands of the job and Department of Defense (DoD) guidelines which recommend separation from service for those unable to meet body composition standards. This study examines the health service utilization of active duty, male Army soldiers in order to determine the prevalence of obesity and overweight and to estimate the effects of these conditions on readiness. MATERIALS AND METHODS: This was a cross-sectional study utilizing fiscal year (FY) 2015 TRICARE claims and military treatment facility (MTF) encounter data obtained from the Military Health System Data Repository (MDR), for 467,732 US Army male Soldiers on active duty. We obtained basic demographic information (age, race, and rank) from the Defense Enrollment Eligibility Reporting System (DEERS). Next, we calculated BMI for this cohort by matching patients to their vital statistics of height and weight measurements. Finally, we obtained their health service utilization by querying and matching patients to their healthcare claims in 2015 by major diagnostic category. FINDINGS: More than half (51.2%) of subjects had overweight, 28.9% had normal weight, 19.7% had obesity, and less than 1% had underweight. Soldiers with overweight and obesity were most common among the 25-34 years age range and enlisted ranks. Normal weight and underweight soldiers had a median of 7 healthcare visits in FY 2015, compared with 8 for soldiers with overweight and 12 for those with obesity. Soldiers with obesity, but not overweight, had a disproportionately greater number of healthcare encounters for diagnostic categories including musculoskeletal; mental health; ear, nose, and throat; and endocrine system. In contrast, soldiers with obesity had disproportionately fewer healthcare encounters for multiple significant trauma and for infectious and parasitic diseases. CONCLUSIONS: More than 70% of soldiers had overweight or obesity in FY 2015, showing the highest prevalence yet measured for these conditions. Previous reports of lower prevalence may be due to the inclusion of circumference-based body fat assessments, which have been criticized for inaccuracy. In our study, disproportionately high health service use by soldiers with obesity suggests decreased readiness, as these soldiers may experience both poorer health and lose necessary training time due to increased provider visits. Proportional usage by soldiers with overweight suggests the protective effect of regular physical activity, though these soldiers should be monitored to ensure that they do not progress to obesity. Additional research should establish the burden of cost, absenteeism, and presenteeism of obesity on the MHS, as well as developing more appropriate field tests for body fat assessment and BMI standards to better support military readiness.

OBJECTIVE: To investigate factors associated with delay in initiation of initial disease-modifying antirheumatic drug (DMARD) in patients newly diagnosed with rheumatoid arthritis (RA). METHODS: We performed a retrospective cohort descriptive study using administrative data from the US military's TRICARE program (2007-2012). We identified incident RA cases using billing codes and initial DMARD receipt using prescription fill date. We quantified the time between RA presentation and initial DMARD receipt, evaluated temporal changes in delay over the study period, and investigated predictors of treatment delay (>â¯90 days) using logistic regression. RESULTS: We identified 16,680 patients with incident RA that were prescribed DMARDs and mean age was 47.2 (SD 13.5) years. The mean time from initial RA presentation to first DMARD prescription receipt was 125.3days (SD 175.4). Over one-third (35.6%) of incident RA patients initiated DMARDâ¯>â¯90days after presentation. There was less treatment delay in later years of the study (mean days to DMARD of 144.7days in 2007; 109.7days in 2012). Patients prescribed opioids had mean time to DMARD of 212.8days (SD 207.4) compared to mean of 77.3days (SD 132.3) for those who did not use opioids (pâ¯<â¯0.0001). Patients prescribed opioids between RA presentation and initial DMARD receipt were more likely to have delay in initial DMARD (OR 4.07, 95% CI: 3.78-4.37). CONCLUSION: In this large US nationwide study, delays in initial DMARD receipt for incident RA were common but time to treatment improved in recent years. While further analysis using clinical data is warranted, these findings suggest that limiting opioid use in patients newly presenting with RA may decrease delay in initiating DMARDs.

OBJECTIVE: Four-dimensional flow cardiovascular magnetic resonance may improve assessment of hemodynamics in patients with aortic dissection. The purpose of this study was to evaluate the feasibility and accuracy of 4-dimensional flow cardiovascular magnetic resonance assessment of true and false lumens flow. METHODS: Thirteen ex vivo porcine aortic dissection models were mounted to a flow loop. Four-dimensional flow cardiovascular magnetic resonance and 2-dimensional phase-contrast cardiovascular magnetic resonance measurements were performed, assessed for intraobserver and interobserver variability, and compared with a reference standard of sonotransducer flow volume measurements. Intraobserver and interobserver variability of 4-dimensional flow cardiovascular magnetic resonance were also assessed in 14 patients with aortic dissection and compared with 2-dimensional phase-contrast cardiovascular magnetic resonance. RESULTS: In the ex vivo model, the intraobserver and interobserver measurements had Lin's correlation coefficients of 0.98 and 0.96 and mean differences of 0.17 (±3.65) mL/beat and -0.59 (±5.33) mL/beat, respectively; 4-dimensional and sonotransducer measurements had a Lin's concordance correlation coefficient of 0.95 with a mean difference of 0.35 (±4.92) mL/beat, respectively. In patients with aortic dissection, the intraobserver and interobserver measurements had Lin's concordance correlation coefficients of 0.98 and 0.97 and mean differences of -0.95 (±8.24) mL/beat and 0.62 (±10.05) mL/beat, respectively; 4-dimensional and 2-dimensional flow had a Lin's concordance correlation coefficient of 0.91 with a mean difference of -9.27 (±17.79) mL/beat because of consistently higher flow measured with 4-dimensional flow cardiovascular magnetic resonance in the ascending aorta. CONCLUSIONS: Four-dimensional flow cardiovascular magnetic resonance is feasible in patients with aortic dissection and can reliably assess flow in the true and false lumens of the aorta. This promotes potential future work on functional assessment of aortic dissection hemodynamics.

Objectives: The Military Healthcare System (MHS) shows increasing interest in acupuncture as an alternative to opioids for pain control. However, specific factors associated with this procedure in the MHS are not well-described in literature. This study examines usage within the MHS to determine patterns among the diagnoses, provider types, and facilities associated with acupuncture. Materials and Methods: Acupuncture-treated patients were identified from TRICARE claims data in the MHS Data Repository as having at least one acupuncture treatment in fiscal year (FY) 2014. Bivariate analysis was performed to determine demographics, diagnoses, and number of visits, for both active-duty and nonactive-duty personnel. Descriptive statistics were used to show associated provider and facility types. Results: A total of 15,761 people received acupuncture in the MHS in FY 2014. Use of acupuncture was greater for Army service, white race, and senior enlisted rank overall, and for males ages 26-35 among active-duty and females ages 46-64 among nonactive-duty beneficiaries. A cumulative 76% of diagnoses were for musculoskeletal or nerve and system issues. Approximately 60% of patients received acupuncture from physicians, 16% from physical therapists or chiropractors, and 9.7% from physician extenders. Specific acupuncture techniques (traditional, auricular, etc.) could not be determined from the data set. Conclusions: The most common diagnoses associated with acupuncture are consistent with pain management. However, full analysis is hampered by inconsistent coding and lack of granularity regarding specific techniques. Given the popularity of acupuncture in the MHS, further research is necessary to explore the full scope of this intervention.
ABSTRACT
INTRODUCTION: Many non-battle injuries among deployed soldiers are due to occupational-related tasks. Given that non-battle injuries are a significant cause of morbidity and mortality, occupational safety and health are of great concern to the military. Some of the leading causes of non-battle injuries in the military are also common in non-military occupational settings. Nationally, falls and motor-vehicle accidents are leading causes of non-fatal occupational injuries in the civilian workforce. The objective of this research is to identify the leading causes, types, and anatomic locations of non-fatal non-battle injuries in Afghanistan and Iraq. METHODS: Non-battle injuries were identified from medical air evacuation records. Causes of air evacuated injuries were identified and coded using the diagnosis and narrative patient history in the air evacuation records. Descriptive statistics were used to report the air evacuated non-battle injury rates, causes, injury types, and anatomic locations. RESULTS: Between 2001 and 2013, there were 68,349 medical air evacuations from Afghanistan and Iraq. Non-battle injuries accounted for 31% of air evacuations from Afghanistan and 34% from Iraq. These injuries were the leading diagnosis category for air evacuations. The three leading causes of injury for Afghanistan and Iraq, respectively, were sports/physical training (23% and 24%), falls/jumps (19% and 16%), and military vehicle-related accidents (8% and 11%). The leading injury types were fractures (21%), overuse pain and inflammation (16%), and dislocations (11%). PRACTICAL APPLICATIONS: Given that over 30% of medical evacuations of soldiers result from non-battle injuries, prevention of such conditions would substantially enhance military readiness during combat.

Intraocular foreign bodies (IOFBs) may be associated with occult exit wounds. The authors present a case of a man who sustained a zipper-tooth IOFB through the cornea from a car tire explosion. CT showed an IOFB within the vitreous cavity, but the IOFB was not identified during vitrectomy. Extension of the peritomy revealed an exit wound with the foreign body lodged in the extraocular space. This case demonstrates that IOFBs can rest within the vitreous cavity after creating an exit wound, but may escape detection by being driven back out of the globe during vitrectomy due to the pressurized eye. Coexistent ocular surface and intraocular pathology often limit intraoperative visualization, but a perforating through-and-through injury should be suspected if the IOFB cannot be identified during vitrectomy.

The application of three-dimensional (3D) printing enables the creation of material objects from digital images by depositing layers of plastic material into 3D structures and can be used for training, education, and surgical planning. We report two patients with large complex cardiac tumors where 3D technology was utilized to analyze the tumor size, location, and extension more precisely, allowing better preoperative planning and decision making.
