An expanded chronic care management approach to multiple chronic conditions in Hispanics using community health workers as community extenders in the Rio Grande Valley of Texas.

INTRODUCTION: The synergistic negative effects of type 2 diabetes (T2DM) and hypertension increases all-cause mortality and the medical complexity of management, which disproportionately impact Hispanics who face barriers to healthcare access. The Salud y Vida intervention was delivered to Hispanic adults living along the Texas-Mexico Border with comorbid poorly controlled T2DM and hypertension. The Salud y Vida multicomponent intervention incorporated community health workers (CHWs) into an expanded chronic care management model to deliver home-based follow-up visits and provided community-based diabetes self-management education. METHODS: We conducted multivariable longitudinal analysis to examine the longitudinal intervention effect on reducing systolic and diastolic blood pressure among 3806 participants enrolled between 2013 and 2019. Participants were compared according to their program participation as either higher (≥ 10 combined educational classes and CHW visits) or lower engagement (<10 encounters). Data was collected between 2013 and 2020. RESULTS: Baseline mean systolic and diastolic blood pressure were 138 and 81 mmHg respectively. There were overall improvements in systolic (-6.49; 95% CI = [-7.13, -5.85]; p < 0.001) and diastolic blood pressure (-3.97; 95% CI = [-4.37, -3.56]; p < 0.001). The higher engagement group had greater systolic blood pressure reduction at 3 months (adjusted mean difference = -1.8 mmHg; 95% CI = [-3.2, -0.3]; p = 0.016) and at 15 month follow-up (adjusted mean difference = -2.3 mmHg; 95% CI = [-4.2, -0.39]; p = 0.0225) compared to the lower engagement group. CONCLUSION: This intervention, tested and delivered in a real-world setting, provides an example of how CHW integration into an expanded chronic care model can improve blood pressure outcomes for individuals with co-morbidities.

Beyond the Diagnosis: Evaluation of Quality-of-Life Measures and Family Functioning in SLC6A1-Related Neurodevelopmental Disorder.

BACKGROUND: SLC6A1-related neurodevelopmental disorder (SLC6A1-NDD) is a rare genetic disorder linked to autism spectrum disorder, epilepsy, and developmental delay. In preparation for future clinical trials, understanding how the disorder impacts patients and their families is critically important. Quality-of-life (QoL) measures capture the overall disease experience of patients. This study presents QOL findings from our SLC6A1-NDD clinical trial readiness study and the Simons Searchlight SLC6A1-NDD registry. METHODS: We compiled QoL data from participants with SLC6A1-NDD enrolled in our clinical trial readiness study (n = 20) and the Simons Searchlight registry (n = 32). We assessed the distribution of scores on the Quality-of-Life Inventory-Disability (QI Disability), Quality of Life of Childhood Epilepsy (QOLCE-55), and Pediatric Quality of Life Inventory Family Impact Module (PedsQL-FIM) administered to caregivers. RESULTS: In our cohort of 52 participants, the mean QI Disability total score was 73 ± 12.3, the QOLCE-55 mean total score was 49 ± 17.1, and the mean total PedsQL score was 51 ± 17.6. Longitudinal QoL scores for a subset of participants (n = 7) demonstrated a reduction in the Family Relationship domain of PedsQL-FIM (Δ-10.0, P = 0.035). Bootstrap resampling of total scores displays nonoverlapping 95% confidence intervals for the 10th, 50th, and 90th percentiles on all three measures. CONCLUSIONS: This is the first study to investigate QoL measures for SLC6A1-NDD. Findings suggest that scores within the 10th percentile's confidence interval could be clinically significant, referring to QI-Disability scores of <61, QOLCE-55 scores of <46, and PedsQL-FIM scores of <42. Future validation studies are needed.

Concentrations of dehydroepiandrosterone-sulphate (DHEA-S) in people with cystic fibrosis on and off elexacaftor-tezacaftor-ivacaftor.

BACKGROUND: Levels of sulfated Dehydroepiandrosterone (DHEA-S) are unknown in people with Cystic Fibrosis (pwCF). DHEA-S is reported to have an inverse association with inflammation and warrants evaluation in pwCF. METHODS: We compared differences in DHEA-S and other hormones between pwCF (n = 180) and without CF (n = 180) and DHEA-S association with percent predicted forced expiratory volume in one second (ppFEV1). We also evaluated DHEA-S levels in people with CF on elexacaftor-tezacaftor-ivacaftor (ETI) (n = 145). RESULTS: PwCF (not on ETI) had lower DHEA-S levels compared to healthy non-CF controls. DHEA-S levels in individuals with CF on ETI were similar to those without CF. Lower DHEA-S levels were associated with lower ppFEV1. CONCLUSIONS: PwCF (not on ETI) have lower levels of DHEA-S than people without CF or people with CF on ETI. Additional studies are needed to investigate the impact of DHEA-S on the health of pwCF and mechanisms involved.

Association of in-line digestive enzyme cartridge with enteral feeds on improvement in anthropometrics among pediatric patients with cystic fibrosis.

BACKGROUND: Approximately 85% of patients with cystic fibrosis (CF) have exocrine pancreatic insufficiency (EPI) with 10% requiring supplemental nighttime enteral tube feedings. Administration of pancreatic enzyme replacement therapy (PERT) with nighttime feedings is fraught with challenges. RELiZORB (Alcresta Therapeutics, Inc), an in-line lipase cartridge, delivers PERT continuously with enteral feedings. Outcomes related to the use of this in-line lipase cartridge are lesser known. This project evaluated anthropometrics related to in-line lipase cartridge use among pediatric patients with CF already receiving oral PERT therapy prior to nighttime enteral feedings. METHODS: Retrospective chart review was performed on 29 patients with CF and EPI receiving supplemental tube feedings and utilizing in-line lipase cartridge for a continuous 12 month period between 2015 and 2019. Anthropometrics were evaluated 12 months before and after initiation of in-line lipase cartridge. RESULTS: Compared with mean height z score at 6-months pre-in-line lipase cartridge, mean height z score at 6-months post-in-line-lipase cartridge (adjusted mean difference [AMD] = 0.2540; 95% CI = [0.0487, 0.4592]; P = 0.0153) and mean height z score at 12-months post-in-line lipase cartridge (AMD = 0.2684; 95% CI = [0.0203, 0.5166]; P = 0.0340) were significantly higher. Mean weight z score at 12-months post-in-line-lipase-cartridge neared statistical significance compared with 6-months pre-in-line lipase cartridge (AMD = 0.2816; 95% CI = [-0.0003, 0.5634]; P = 0.0502) when excluding seven patients with advanced lung disease (forced expiratory volume in the first second of expiration of 40%). Weight-for-length or body mass index did not significantly differ compared with pre-in-line lipase cartridge. CONCLUSION: Use of in-line lipase cartridge with enteral feeds improved anthropometrics, especially height, in pediatric patients with CF.

Risk of Obstructive Sleep Apnea, Chronic Dizziness, and Sleep Duration.

BACKGROUND: Although it is recommended that obstructive sleep apnea (OSA) be screened for using a validated self-report questionnaire in patients experiencing dizziness, there is still a lack of research on the relationship between high risk of OSA and chronic dizziness. OBJECTIVES: The study aimed to examine the relationship between the high risk of OSA and chronic dizziness and investigate how this relationship is affected by sleep duration. METHODS: This cross-sectional study used data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021). Adults aged 40 years or older were included and divided into two groups using the STOP-Bang questionnaire (SBQ): a high-risk group for OSA or not. Complex samples logistic regression analyses were performed to examine the odds ratios of chronic dizziness based on the national population estimates. RESULTS: Our findings showed that individuals in the high-risk group for OSA were significantly more likely to experience chronic dizziness. Specifically, among subgroups based on sleep duration, the high-risk group for OSA with a short sleep duration of ≤5 hr demonstrated the highest odds of chronic dizziness, showing a significantly 2.48-fold increased likelihood compared to the non-high-risk for OSA with a sleep duration of 5-9 hr. DISCUSSION: The SBQ can be beneficial when other causes do not explain chronic dizziness, helping to rule in the possibility of OSA. Educating individuals suspected of having OSA or who have been diagnosed with OSA about the importance of adequate sleep duration may help reduce the risk of chronic dizziness.

Dynamic Hyperspectral Holography Enabled by Inverse-Designed Metasurfaces with Oblique Helicoidal Cholesterics.

Metasurfaces are flat arrays of nanostructures that allow exquisite control of phase and amplitude of incident light. Although metasurfaces offer new active element for both fundamental science and applications, the challenge still remains to overcome their low information capacity and passive nature. Here, by integrating an inverse-designed-metasurface with oblique helicoidal cholesteric liquid crystal (ChOH ), simultaneous spatial and spectral tunable metasurfaces with a high information capacity for dynamic hyperspectral holography, are demonstrated. The inverse design facilitates a single-phase map encoding of ten independent holographic images at different wavelengths. ChOH provides precise spectral modulation with narrow bandwidth and wide tunable regime in response to programmed stimuli, thus enabling dynamic switching of the multicolor holography. The results provide simple and generalizable principles for the rational design of interactive metasurfaces that will find numerous applications, including security platform.

Intramedullary Positive Tissue Culture Increases the Risk of Reinfection Following One-Stage Septic Revision Total Knee Arthroplasty.

BACKGROUND: Intraoperative acquisition of representative tissue samples is essential during revision arthroplasty of the infected total knee arthroplasty (TKA). While the number of intraoperative tissue samples needed to identify the organism is well described in the literature, there is still a paucity of evidence regarding the location of positive intraoperative samples and their correlation to postoperative outcomes. METHODS: There were forty-two patients who had septic failure following one-stage revision TKA for periprosthetic joint infection who were identified between January 2009 and December 2017. They were matched to a control group of patients who had successful one-stage revision TKA without septic failure. The location of positive intraoperative tissue samples was categorized as: 1) soft tissue; 2) interface between bone and prosthesis; and 3) intramedullary (IM). Chi-square, Student's t-, and Wilcoxon Mann-Whitney U-tests were used as appropriate. Univariate and multivariate logistic regression analyses were performed to evaluate predictors of septic failure. RESULTS: Weight > 100 kilograms (P = .033), higher Charlson Comorbidity Index (P < .001), and positive IM cultures (P < .001) were associated with a higher risk of reinfection after one-stage revision TKA. A positive IM sample carried a nearly five-fold increase in odds of reinfection (odds ratio 4.86, 95% confidence interval 1.85 to 12.78, P = .001). CONCLUSIONS: A positive IM culture sample is significantly associated with septic failure after one-stage exchange for periprosthetic joint infection of the knee. Patients who had positive IM cultures may benefit from longer postoperative antibiotic therapy for the treatment of one-stage exchange arthroplasty to minimize the risk of reinfection.

Framework for dual-energy-like chest radiography image synthesis from single-energy computed tomography based on cycle-consistent generative adversarial network.

BACKGROUND: Dual-energy (DE) chest radiography (CXR) enables the selective imaging of two relevant materials, namely, soft tissue and bone structures, to better characterize various chest pathologies (i.e., lung nodule, bony lesions, etc.) and potentially improve CXR-based diagnosis. Recently, deep-learning-based image synthesis techniques have attracted considerable attention as alternatives to existing DE methods (i.e., dual-exposure-based and sandwich-detector-based methods) because software-based bone-only and bone-suppression images in CXR could be useful. PURPOSE: The objective of this study was to develop a new framework for DE-like CXR image synthesis from single-energy computed tomography (CT) based on a cycle-consistent generative adversarial network. METHODS: The core techniques of the proposed framework are divided into three categories: (1) data configuration from the generation of pseudo CXR from single energy CT, (2) learning of the developed network architecture using pseudo CXR and pseudo-DE imaging using a single-energy CT, and (3) inference of the trained network on real single-energy CXR. We performed a visual inspection and comparative evaluation using various metrics and introduced a figure of image quality (FIQ) to consider the effects of our framework on the spatial resolution and noise in terms of a single index through various test cases. RESULTS: Our results indicate that the proposed framework is effective and exhibits potential synthetic imaging ability for two relevant materials: soft tissue and bone structures. Its effectiveness was validated, and its ability to overcome the limitations associated with DE imaging techniques (e.g., increase in exposure dose owing to the requirement of two acquisitions, and emphasis on noise characteristics) via an artificial intelligence technique was presented. CONCLUSIONS: The developed framework addresses X-ray dose issues in the field of radiation imaging and enables pseudo-DE imaging with single exposure.

Sex differences in outcomes of people with cystic fibrosis treated with elexacaftor/tezacaftor/ivacaftor.

BACKGROUND: There is a well described sex-disparity in outcomes of individuals with cystic fibrosis (CF), with females faring worse than males. Given the dramatic improvement in overall health of people with CF using CF transmembrane conductance regulator (CFTR) modulator therapy, elexacaftor/tezacaftor/ivacaftor (ETI), the sex-disparity in CF warrants re-examination. METHODS: We evaluated the effects of ETI use by sex prior to versus after initiation of ETI by pulmonary exacerbations (PEx), percent predicted forced expiratory volume in one second (ppFEV1), presence of Pseudomonas aeruginosa in sputum cultures, and body mass index (BMI). We used univariate and multivariable longitudinal regression adjusting for key confounders, such as age, race, CFTR modulator taken prior to ETI and baseline ppFEV1. RESULTS: We included 251 individuals started on ETI between January 2014 to September 2022. We collected data for a mean of 5.45 years pre-ETI and 2.38 years post-ETI. We found the adjusted presence of PEx decreased more in males than females pre- to post-ETI with the odds of having a PEx in males being 0.57 (43% reduction) versus females 0.75 (25% reduction) (p = 0.049). We found no statistical difference by sex for ppFEV1, presence of Pseudomonas aeruginosa or BMI pre- to post-ETI by sex. CONCLUSION: After treatment with ETI, there was a greater decline in PEx in males versus females. Long-term impact of ETI by sex is still unknown, but we will need to seek ways to effectively tailor care for individuals with CF and consider pharmacokinetic studies of ETI comparing males to females.

Hepatocellular carcinoma surveillance may be associated with potential psychological harms in patients with cirrhosis.

BACKGROUND AND AIMS: The value of HCC surveillance is determined by the balance between benefits and harms; however, no studies have enumerated psychological harms. APPROACH AND RESULTS: We fielded surveys measuring psychological harms to patients with cirrhosis in a multicenter randomized trial of HCC surveillance outreach. All patients with positive or indeterminate surveillance results and matched patients with negative results were invited to complete surveys measuring (1) depression through the Patient Health Questionnaire-ninth version, (2) anxiety through State-Trait Anxiety Inventory, (3) HCC-specific worry through Psychological Consequences Questionnaire, and (4) decisional regret. Patients were classified into 4 groups: true positive (TP), false positive (FP), indeterminate, and true negative (TN). Multivariable longitudinal regression analysis using the generalized estimating equation method was performed to compare the means of measures across groups. We conducted 89 semistructured interviews in a subset of patients stratified by health system and test results. Of 2872 patients in the trial, 311 completed 1+ follow-up survey (63 FP, 77 indeterminate, 38 TP, and 133 TN). Moderate depression decreased in TN patients, increased in TP, and had intermittent but mild increases in those with FP and indeterminate results. High anxiety temporarily increased in patients with TP results but resolved over time and was stable in those with FP and indeterminate results. Decisional regret was low and did not differ across groups. In semistructured interviews, patients reported apprehension, anxiety, emotional distress, and coping related to HCC surveillance. CONCLUSIONS: Psychological harms of HCC surveillance appear mild but differ by test result. Future research should determine the impact of psychological harms on the value of HCC surveillance programs.

Financial Burden of Hepatocellular Carcinoma Screening in Patients With Cirrhosis.

BACKGROUND: The overall value of hepatocellular carcinoma screening is defined by the balance of benefits and harms. Studies have only reported physical harms with none describing financial harms. METHODS: We conducted a multicenter pragmatic randomized clinical trial of hepatocellular carcinoma screening outreach among 2872 patients with cirrhosis from March 2018 to April 2021. Patients with positive or indeterminate results and matched patients with negative results completed surveys at baseline and at follow-up measuring financial harms via Cancer Self-Administered Questionnaire and financial burden via Comprehensive Score for Financial Toxicity Functional Assessment of Chronic Illness Therapy. Univariable and multivariable longitudinal regression analyses were performed to compare changes in financial harms across groups: true positive, true negative, false positive, and indeterminate. Semistructured interviews were conducted in a subset of patients, sampled by center and test result. RESULTS: Of 311 patients who completed at least 1 follow-up survey (75% response rate), 37 had true positive, 133 true negative, 64 false positive, and 77 indeterminate results. Financial harms increased in true positive and false positive patients with no significant changes noted among those with true negative or indeterminate results. At follow-up, 21.8% of patients reported moderate-severe financial burden, which was not significantly associated with test results. Semistructured interviews revealed variation in the frequency and severity of financial harms based on test results, with increased harm in those with false positive results. CONCLUSIONS: Financial harms of hepatocellular carcinoma screening vary by test result and can pose a barrier that must be considered when determining the optimal screening program.

Thermophysical properties and bonding with composite resin of premixed mineral trioxide aggregate for use as base material.

Dental bases require low thermal conductivity and good mechanical properties, such as bonding with composite resins. This study aims to elucidate the physicochemical properties of premixed mineral trioxide aggregate (MTA) for its suitability as a dental base and to explore the optimal adhesive strategy with composite resin. The thermal conductivity and compressive strength of this premixed MTA are 0.12 W/(m•K) and 93.76 MPa, respectively, Which are deemed adequate for its application as dental base. When bonded to composite resin, the use of 37% phosphoric acid etching before applying the Clearfil SE bond significantly reduced the bonding strength between composite resin and premixed MTA. This was because the compressive strength and Vickers hardness of premixed MTA decreased, and tricalcium silicate was dissolved from the surface during acid etching. Therefore, it is recommended to avoid using 37% phosphoric acid etching when bonding premixed MTA and composite resin as a dental base.

Quantification of collagen content and stromal cellularity within reactive stroma is predictive of prostate cancer biochemical recurrence and specific death.

Semiquantitative reactive stromal grading has been shown to be a predictor of biochemical recurrence and prostate cancer (PCa) specific death. It has been extensively validated. In this study we tested novel technologies to introduce quantitative measures of host response, in particular collagen content and stromal cellularity. We use 3 large retrospective cohorts, the Baylor College of Medicine cohort, the Brady cohort and the Pound cohort. Slides were stained and digitized using image deconvolution and analyzed using image segmentation and image analyses. PicroSirius red stain histochemical stains were used for collagen quantification. Area of cancer and stroma were measured independently, without regard to quality of stroma. Cellularity, in each compartment, was measured using image deconvolution, image segmentation and image analysis. Two biomarkers were tested in 3 independent cohorts with two endpoints, biochemical recurrence and prostate cancer specific death. Stromal cellularity (qCollCell) and stromal collagen area (qCollArea) are independently predictive biochemical recurrence in the Hopkins Brady cohort, particularly in Gleason 6-7 patients. Multivariate analysis demonstrated that increased stroma cellularity (qCollCell) was a significant predictor of PCa specific death, when compared to an established model of PCa, in the Baylor cohort. Stromal collagen (qCollArea) independently predicts PCa-specific death in the Hopkins Pound cohort. The introduction of a computerized quantitative test of the host response increases the probability that this test will be reproducible in other cohorts. The ability to improve prediction of prostate cancer specific death might lie in the study of the host and its response.

Tunable Radiative Cooling by Mechanochromic Electrospun Micro-Nanofiber Matrix.

Radiative thermoregulation has been regarded as an energy-efficient method for thermal management. In this study, the development of a mechanoresponsive polydimethylsiloxane (PDMS) micro-nanofiber matrix capable of both sub-ambient radiative cooling and solar heating is presented, achieved through a core-shell electrospinning technique. The electrospun PDMS micro-nanofibers, with diameters comparable to the solar wavelengths, exhibit excellent solar reflectivity (≈93%) while preserving its pristine high infrared (IR) emissivity. As a result, the electrospun PDMS radiative cooler (EPRC) successfully demonstrated sub-ambient radiative cooling performance (≈3.8°C) during the daytime. Furthermore, the exceptional resilient property of PDMS facilitated the reversible alteration of the structural morphology created by the fiber-based matrix under mechanical force, resulting in the modulation of solar reflectivity (≈80%). The precise modulation of solar reflectivity enabled reversibly switchable multi-step radiative thermoregulation, offering enhanced flexibility in addressing varying thermal environments even in maintaining the desired temperature. The findings of this work offer a promising approach toward dynamic radiative thermoregulation, which holds significant potential for addressing global climate change concerns and energy shortage.

A pilot randomized controlled trial comparing nutritious meal kits and no-prep meals to improve food security and diet quality among food pantry clients.

BACKGROUND: Food pantry clients have high rates of food insecurity and greater risk for and prevalence of diet-related diseases. Many clients face time, resource, and physical constraints that limit their ability to prepare healthy meals using foods typically provided by pantries. We compared two novel approaches to alleviate those barriers and encourage healthier eating: meal kits, which bundle ingredients with a recipe on how to prepare a healthy meal, and nutritious no-prep meals, which can be eaten after thawing or microwaving. METHODS: Participants were adult pantry clients from a large food pantry in the Southern sector of Dallas, Texas. We conducted a repeated measures between-subjects study with 70 clients randomized to receive 14-days of meal kits (n = 35) or no-prep meals (n = 35). Participants completed questionnaires at baseline and two-week follow-up on demographics, hedonic liking of study meals, perceived dietary quality, and food security. Two-way repeated measures analysis of variance was used to examine group and time effects, and group by time interactions. We also describe feasibility and satisfaction outcomes to inform future implementation. RESULTS: Sixty-six participants completed the study (94%). Participants were predominantly Hispanic or Latino(a) (63%) and African American or Black (31%) women (90%). There was a significant interaction on hedonic liking of study meals (ηp²=0.16, F(1,64) = 11.78, p < .001), such that participants that received meal kits had greater improvements in hedonic liking over time than participants in the no-prep group. We observed significant improvements in perceived dietary quality (ηp²=0.36, F(1,64) = 36.38, p < .001) and food security (ηp²=0.36, F(1,64) = 36.38, p < .001) across both groups over time, but no between group differences or significant interactions indicating one intervention was more effective than the other. Program satisfaction was high across both groups, but higher among the meal kit group (ηp²=0.09, F(1,64) = 6.28, p = .015). CONCLUSIONS: Results suggest nutritious meal kits and no-prep meals may be desirable nutrition intervention strategies for pantry clients and have potential to increase food security and perceived dietary quality in the short-term. Our findings are limited by a small sample and short follow-up. Future studies should continue to test both interventions, and include longer follow-up, objective measures of dietary quality, and relevant clinical outcomes. TRIAL REGISTRATION: This trial was registered on 25/10/2022 on ClinicalTrials.gov, identifier: NCT05593510.

Cr-catalysed ethylene dimerization in an ionic liquid-organic solvent biphasic system with perfect 1-butene selectivity.

Cr-catalyzed ionic liquid-organic biphasic ethylene dimerization was realized with 100% 1-butene selectivity. The perfect α-olefin selectivity can be rationalized in terms of the poor solubility of the oligomerized long-chain olefins in ionic liquids, and enables the establishment of a dimerization process without any complicated and energy-intensive catalyst and byproduct separation processes.

Accelerated Single Li-Ion Transport in Solid Electrolytes for Lithium-Sulfur Batteries: Poly(Arylene Ether Sulfone) Grafted with Pyrrolidinium-Terminated Poly(Ethylene Glycol).

Polymeric solid electrolytes have attracted tremendous interest in high-safety and high-energy capacity lithium-sulfur (Li─S) batteries. There is, however, still a dilemma to concurrently attain high Li-ion conductivity and high mechanical strength that effectively suppress the Li-dendrite growth. Accordingly, a rapidly Li-ion conducting solid electrolyte is prepared by grafting pyrrolidinium cation (PYR+ )-functionalized poly(ethylene glycol) onto the poly(arylene ether sulfone) backbone (PAES-g-2PEGPYR). The PYR+ groups effectively immobilize anions of Li-salts in Li-conductive PEGPYR domains phase-separated from PAES matrix to enhance the single-ion conduction. The tailored PAES-g-2PEGPYR membrane shows a high Li-ion transference number of 0.601 and superior ionic conductivity of 1.38 mS cm-1 in the flexible solid state with the tensile strength of 1.0 MPa and Young's modulus of 1.5 MPa. Moreover, this PAES-g-2PEGPYR membrane exhibits a high oxidation potential (5.5 V) and high thermal stability up to 200 (C. The Li/PAES-g-2PEGPYR/Li cell stably operates for 1000 h without any short circuit, and the rechargeable Li/PAES-g-2PEGPYR/S cell discharges a capacity of 1004.7 mAh g-1 at C/5 with the excellent rate capability and the prominent cycling performance of 95.3% retention after 200 cycles.

GS Hip Nail versus Affixus Hip Fracture Nail for the Intramedullary Nailing of Intertrochanteric Fractures.

BACKGROUND: Intertrochanteric fractures are a global health concern, especially in aging populations like the Republic of Korea. Surgical treatments like intramedullary nailing are preferred for their benefit. Various hip nails are used worldwide, each with unique features and challenges. This study aims to compare the GS hip nail with the Affixus hip fracture nail for the treatment of intertrochanteric fractures. MATERIAL AND METHODS: This retrospective study, conducted at a single center, included 179 patients who underwent intramedullary nailing for intertrochanteric fractures using the GS hip nail or the Affixus hip fracture nail. Excluding specific cases, 43 patients in the GS group and 46 in the Affixus group met the minimum 6-month follow-up criteria. RESULT: The GS group exhibited a significantly shorter mean operation time (43.26 min) compared to the Affixus group (51.11 min). Radiographically, both groups showed no significant differences in their reduction quality, tip, and apex distance (TAD), or Cleveland index in the immediate postoperative window. However, the GS group achieved a greater valgus reduction based on the contralateral femoral neck shaft angle (NSA). At 6 months post-operation, there were no significant differences in TAD or advancement and sliding distances. Complication rates were similar between the two groups, with no implant breakages. Clinical outcomes, as measured via mHHS and EQ-5D-5L, showed no significant differences. Despite a slightly higher implant cost, the GS group had a lower total hospital cost than the Affixus group, but this was not statistically significant. CONCLUSIONS: This study highlights the efficiency of the GS hip nail in reducing the operation time compared to the Affixus hip fracture nail with comparable radiologic and clinical outcomes. Further research with long-term follow-up and larger patient studies are needed to fully assess its effectiveness in improving patient outcomes in hip fracture treatment.

SNAP Participation Moderates Fruit and Vegetable Intake Among Minority Families With Low Income.

OBJECTIVE: To examine the moderation effect of Supplemental Nutrition Assistance Program (SNAP) participation on the baseline fruit and vegetable (FV) intake of Hispanic/Latino and African American children and parents participating in the Brighter Bites program. DESIGN: Cross-sectional. SETTING: Houston, Austin, and Dallas, TX; Washington, DC; and Southwest Florida. PARTICIPANTS: Self-reported surveys (n = 6,037) of Hispanic/Latino and African American adult-child dyads enrolled in Brighter Bites in Fall 2018. VARIABLES MEASURED: Dependent variable, child FV intake; Independent variable, parent FV intake, and FV shopping behavior; Effect Measure Modifier, SNAP participation. ANALYSIS: Quantitatively used mixed effects linear regression models to test if the effect of parental baseline FV intake and shopping behavior on a child's baseline FV intake differed by SNAP participation. Analyses were performed using STATA with significance set at P < 0.05 and 95% confidence intervals (CIs). RESULTS: For parents that consumed FV ≥ 2 times/d at baseline, there was a 0.1 times increase in child FV intake at baseline among those who participated in SNAP as compared with those who did not participate in SNAP (ß = 0.1; 95% CI, 0.1-0.2; P = 0.001), and for parents who shopped at convenience stores ≥ 2 times/wk for FV, there was 0.6 times increase in child FV intake at baseline for those who participated in SNAP as compared with those that did not participate in SNAP (ß = 0.6; 95% CI, 0.3-0.9; P < 0.001). CONCLUSIONS AND IMPLICATIONS: Supplemental Nutrition Assistance Program participation moderated the associations between FV intake among African American and Hispanic/Latino parents and children and FV shopping at convenience stores and child FV intake. Findings indicate a need for future interventions to promote SNAP participation among those eligible and improve access to FV.
