A Framework for Studying Healthcare Equity in Adolescent Idiopathic Scoliosis: Scoping Review and Meta-Analysis of Existing Literature

J Am Acad Orthop Surg. 2023 Nov 22. doi: 10.5435/JAAOS-D-23-00296. Online ahead of print.

ABSTRACT

INTRODUCTION: Health inequities remain a notable barrier for pediatric patients, especially in conditions such as adolescent idiopathic scoliosis (AIS), where the efficacy of nonsurgical treatment is dependent on early diagnosis and referral to a specialist. Social determinants of health (SDOH) are nonmedical factors that affect health outcomes, such as economic stability, neighborhood environment, and discrimination. Although these factors have been studied throughout the AIS literature, considerable inconsistencies remain across studies regarding the investigation of SDOH for this population. Through a scoping review, we analyze the existing literature to propose a comprehensive framework to consider when designing future prospective and retrospective studies of healthcare equity in AIS.

METHODS: A systematic review was executed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. A meta-analysis was performed for each reported SDOH (race, ethnicity, insurance provider, and socioeconomic status) including only studies with complete and consistent variables and outcomes. Cobb angle measurements were aggregated and summarized as the weighted mean difference with 95% confidence interval using a fixed or random-effects model (substantial heterogeneity identified).

RESULTS: Of 7,539 studies reviewed, nine studies met all the inclusion criteria. As expected, considerable inconsistencies were found across the nine studies making it difficult to aggregate data. Within the meta-analyses, the mean difference between White non-Hispanic and Hispanic patients was statistically significant (1.71; 95% confidence interval 0.78 to 2.65; P < 0.001). No other statistically significant differences were identified among the SDOH and presenting main Cobb angle magnitude.

CONCLUSION: These studies provide insight into healthcare inequities in AIS, although notable inconsistencies make it difficult to aggregate data and draw the conclusions needed to drive necessary public health changes. However, our proposed framework can provide a guideline for future prospective and retrospective studies to standardize data reporting and allow for improved collaboration, study design, and future systematic reviews and meta-analyses.

Laryngoscopy-based scoring system for the diagnosis of vocal fold leukoplakia

J Laryngol Otol. 2023 Apr 26:1-7. doi: 10.1017/S0022215123000683. Online ahead of print.

ABSTRACT

OBJECTIVE: To propose a scoring system based on laryngoscopic characteristics for the differential diagnosis of benign and malignant vocal fold leukoplakia.

METHODS: Laryngoscopic images from 200 vocal fold leukoplakia cases were retrospectively analysed. The laryngoscopic signs of benign and malignant vocal fold leukoplakia were compared, and statistically significant features were assigned and accumulated to establish the leukoplakia finding score.

RESULTS: A total of five indicators associated with malignant vocal fold leukoplakia were included to construct the leukoplakia finding score, with a possible range of 0-10 points. A score of 6 points or more was indicative of a diagnosis of malignant vocal fold leukoplakia. The sensitivity, specificity and accuracy values of the leukoplakia finding score were 93.8 per cent, 83.6 per cent and 86.0 per cent, respectively. The consistency in the leukoplakia finding score obtained by different laryngologists was strong (kappa = 0.809).

CONCLUSION: This scoring system based on laryngoscopic characteristics has high diagnostic value for distinguishing benign and malignant vocal fold leukoplakia.

Ultra-high-performance liquid chromatography-quadrupole-time of flight-mass spectrometry combined with network pharmacology for analysis of potential quality markers of three processed products of Qingpi

J Sep Sci. 2023 Nov 23:e2300281. doi: 10.1002/jssc.202300281. Online ahead of print.

ABSTRACT

Qingpi, a well-known traditional Chinese medicine for qi-regulating and commonly processed into three types of pieces, has been widely used in the clinical application of liver disease for thousands of years. In this study, an ultra-high-performance liquid chromatography-quadrupole-time of flight-mass spectrometry approach along with multivariate statistical analysis was developed to assess and characterize the differentiations of three processed products and confirm the potential quality markers of Qingpi. In addition, a systematic analysis combined with network pharmacology and molecular docking was performed to clarify the potential mechanism of Qingpi for the treatment of liver disease. As a result, 18 components were identified and an integrated network of Qingpi-Components-Target-Pathway-Liver Disease was constructed. Eight compounds were finally screened out as the potential quality markers acting on ten main targets and pathways of liver disease. Molecular docking analysis results indicated that the quality markers had a good binding activity with the targets. Overall, this work preliminarily identified the potential quality markers of three processed products of Qingpi, and predicted its targets in the prevention and treatment of liver disease, which can provide supporting information for further study of the pharmacodynamic substances and mechanisms of Qingpi.

Investigation of BAK, BAX and MAD2L1 gene expression in human aneuploid blastocysts

Zygote. 2023 Nov 23:1-7. doi: 10.1017/S0967199423000539. Online ahead of print.

ABSTRACT

Maintaining genomic stability is crucial for normal development. At earlier stages of preimplantation development, as the embryonic genome activation is not fully completed, the embryos may be more prone to abnormalities. Aneuploidies are one of the most common genetic causes of implantation failure or first-trimester miscarriages. Apoptosis is a crucial mechanism to eliminate damaged or abnormal cells from the organism to enable healthy growth. Therefore, this study aimed to determine the relationship between the expression levels of genes involved in apoptosis in human aneuploid and euploid blastocysts. In total, 32 human embryos obtained from 21 patients were used for this study. Trophectoderm biopsies were performed and next-generation screening was carried out for aneuploidy screening. Total RNA was extracted from each blastocyst separately and cDNA was synthesized. Gene expression levels were evaluated using RT-PCR. The statistical analysis was performed to evaluate the gene expression level variations in the euploid and aneuploid embryos, respectively. The expression level of the BAX gene was significantly different between the aneuploid and euploid samples. BAX expression levels were found to be 1.5-fold lower in aneuploid cells. However, the expression levels of BAK and MAD2L1 genes were similar in each group. This study aimed to investigate the possible role of genes involved in apoptosis and aneuploidy mechanisms. The findings of this investigation revealed that the BAX gene was expressed significantly differently between aneuploid and euploid embryos. Therefore, it is possible that the genes involved in the apoptotic pathway have a role in the aneuploidy mechanism.

Characteristics of Overdose Deaths Related to Illicitly Manufactured Fentanyl – Arizona, July 2019 – June 2020

J Psychoactive Drugs. 2023 Nov 23:1-9. doi: 10.1080/02791072.2023.2284341. Online ahead of print.

ABSTRACT

Using the Arizona State Unintentional Drug Overdose Reporting System (AZ-SUDORS), the study aims to identify the social and drug characteristics of illicitly manufactured fentanyl (IMF)-related overdose deaths. The data include drug overdose deaths from July 1, 2019 to June 30, 2020. Decedents were categorized into four groups by types of opioids detected: (1) IMF-positive; (2) heroin-positive (negative for IMF); (3) pharmaceutical opioid-positive (negative for heroin or IMF); (4) nonopioid. Bivariate statistics were used to compare differences between IMF and other groups. Among 2,029 decedents, 77.8% tested positive for opioids. The IMF group included 57.9%, the heroin group included 9.5%, the pharmaceutical opioid group 10.5%, and the nonopioid group 22.2%. The IMF group was younger (mean age 35.0), more likely to be from a large urban area (78.2%), and with a greater proportion of ethnic/racial minorities (48.6%), compared to the other three groups. The IMF group was less likely to test positive for methamphetamine (24.9%), compared to heroin (63.7%) or pharmaceutical opioid groups (34.0%), but more likely to test positive for cannabis (31.3%), compared to the other three groups. Our data show disproportionate IMF impacts on younger persons and ethnic minorities. Interventions need to be tailored to account for distinct psychosocial profiles associated with IMF use.

Screen-Based Patient Simulation: An Exemplar for Developing and Assessing Competency

Nurse Educ. 2023 Nov 22. doi: 10.1097/NNE.0000000000001585. Online ahead of print.

ABSTRACT

BACKGROUND: Nursing education is moving toward competency-based education and assessment. Nurse educators will need to adopt strategies to develop and measure competence.

PURPOSE: The purpose of this study was to determine if screen-based virtual patient simulation is an effective strategy to assist learners in developing competencies and subcompetencies required in nursing practice.

METHODS: Thirteen questions (6 assessment and clinical reasoning focused, 4 clinical judgment focused, 3 attitude and socialization to nursing focused), aligned with the competencies of the American Association of Colleges of Nursing Essentials, were developed for a pre-/posttest design to evaluate student competency development.

RESULTS: Senior nursing students (n = 52) participated; 1-tailed paired t test identified 12 of 13 items as statistically significant. Posttest scores were greater than pretest scores.

CONCLUSIONS: The change in mean scores from pre- to posttest suggests screen-based virtual patient simulation scenarios improve learners’ competence in addressing the patient’s physical and psychological comfort and decreased caregiver biases.

Loop Ileostomy Closure as a 23-Hour Stay Procedure With Preoperative Efferent Limb Enteral Stimulation: A Randomized Controlled Trial

Dis Colon Rectum. 2023 Nov 16. doi: 10.1097/DCR.0000000000003111. Online ahead of print.

ABSTRACT

BACKGROUND: Loop ileostomy closure is a common procedure in colorectal surgery. Often seen as a simple operation associated with low complication rates, it still leads to lengthy hospitalizations. Reducing postoperative complications and ileus rates could lead to a shorter length of stay and even ambulatory surgery.

OBJECTIVES: This study aimed to assess the safety and feasibility of ileostomy closure performed in a 23-hour hospitalization setting using a standardized enhanced recovery pathway.

DESIGN: Randomized controlled trial.

SETTINGS: Two high-volume colorectal surgery centers.

PATIENTS: Healthy adults undergoing elective ileostomy closure, from July 2019 to January 2022.

INTERVENTION: All patients were enrolled in a standardized enhanced recovery pathway specific to ileostomy closure including daily irrigation of efferent limb with a nutritional formula for 7 days prior to surgery. Patients were randomly allocated to either conventional hospitalization (n = 23) or a 23-hour stay (n = 24).

MAIN OUTCOME MEASURES: Primary outcome was total length of stay and secondary outcomes were 30-day rates of readmission, postoperative ileus, surgical site infections, postoperative morbidity and mortality.

RESULTS: A total of 47 patients were ultimately randomized. Patients in the 23-hour hospitalization arm had a shorter median length of stay (1 day vs. 2 days, p = 0.02) and similar rates of readmission (4% vs. 13%, p = 0.35), postoperative ileus (none in both arms), surgical site infection (0 vs. 4%, p = 0.49), postoperative morbidity (21% vs. 22%, p = 1.00) and mortality (none in both arms).

LIMITATIONS: Due to COVID-19, access to surgical beds was greatly limited, leading to a shift toward ambulatory surgery for ileostomy closure. The study was terminated early, which affected its statistical power.

CONCLUSION: Loop ileostomy closures as 23-hour stay procedures are feasible and safe. Ileus rate might be reduced by preoperative intestinal stimulation with nutritional formula through stoma’s efferent limb, although specific RCTs are needed to confirm this association.

Construction and validation of a risk prediction model for acute kidney injury in patients after cardiac arrest

Ren Fail. 2023;45(2):2285865. doi: 10.1080/0886022X.2023.2285865. Epub 2023 Nov 23.

ABSTRACT

OBJECTIVE: Identifying patients at high risk for cardiac arrest-associated acute kidney injury (CA-AKI) helps in early preventive interventions. This study aimed to establish and validate a high-risk nomogram for CA-AKI.

METHODS: In this retrospective dataset, 339 patients after cardiac arrest (CA) were enrolled and randomized into a training or testing dataset. The Student’s t-test, non-parametric Mann-Whitney U test, or χ2 test was used to compare differences between the two groups. Optimal predictors of CA-AKI were determined using the Least Absolute Shrinkage and Selection Operator (LASSO). A nomogram was developed to predict the early onset of CA-AKI. The performance of the nomogram was assessed using metrics such as area under the curve (AUC), calibration curves, decision curve analysis (DCA), and clinical impact curve (CIC).

RESULTS: In total, 150 patients (44.2%) were diagnosed with CA-AKI. Four independent risk predictors were identified and integrated into the nomogram: chronic kidney disease, albumin level, shock, and heart rate. Receiver operating characteristic (ROC) analyses showed that the nomogram had a good discrimination performance for CA-AKI in the training dataset 0.774 (95%CI, 0.715-0.833) and testing dataset 0.763 (95%CI, 0.670-0.856). The AUC values for the two groups were calculated and compared using the Hanley-McNeil test. No statistically significant differences were observed between the groups. The calibration curve demonstrated good agreement between the predicted outcome and actual observations. Good clinical usefulness was identified using DCA and CIC.

CONCLUSION: An easy-to-use nomogram for predicting CA-AKI was established and validated, and the prediction efficiency of the clinical model has reasonable clinical practicability.

Anastomotic Leakage in Relation to Type of Mesorectal Excision and Defunctioning Stoma Use in Anterior Resection for Rectal Cancer

Dis Colon Rectum. 2023 Nov 16. doi: 10.1097/DCR.0000000000003050. Online ahead of print.

ABSTRACT

BACKGROUND: Anastomotic leakage after anterior resection for rectal cancer is more common after total compared to partial mesorectal excision but might be mitigated by a defunctioning stoma.

OBJECTIVE: The aim is to assess how anastomotic leakage is affected by type of mesorectal excision and defunctioning stoma use.

DESIGN: This is a retrospective multicenter cohort study evaluating anastomotic leakage after anterior resection. Multivariable Cox regression with hazard ratios and 95% confidence intervals was employed to contrast mesorectal excision types and defunctioning stoma use with respect to anastomotic leakage, with adjustment for confounding.

SETTINGS: This multicenter study included patients from 11 Swedish hospitals between 2014 and 2018.

PATIENTS: Patients who underwent anterior resection for rectal cancer were included.

MAIN OUTCOMES MEASURES: Anastomotic leakage rates within and after 30 days of surgery are described up to one year after surgery.

RESULTS: Anastomotic leakage occurred in 24.2% and 9.0% of 1126 patients operated with total and partial mesorectal excision, respectively. Partial compared to total mesorectal excision was associated with a reduction in leakage, with an adjusted HR of 0.46 (95% CI: 0.29-0.74). Early leak rates within 30 days were 14.9% with and 12.5% without a stoma, while late leak rates after 30 days were 7.5% with and 1.9% without a stoma. After adjustment, defunctioning stoma was associated with a lower early leak rate (HR 0.47; 95% CI: 0.28-0.77). However, the late leak rate was non-significantly higher in defunctioned patients (HR 1.69; 95% CI: 0.59-4.85).

LIMITATIONS: This study was limited by its retrospective observational study design.

CONCLUSIONS: Anastomotic leakage is common up to one year after anterior resection for rectal cancer, where partial mesorectal excision is associated with a lower leak rate. Defunctioning stomas seem to decrease the occurrence of leakage, though partially by only delaying the diagnosis.

Risk prediction of the progression of chronic kidney disease stage 1 based on peripheral blood samples: construction and internal validation of a nomogram

Ren Fail. 2023;45(2):2278298. doi: 10.1080/0886022X.2023.2278298. Epub 2023 Nov 23.

ABSTRACT

Patients with chronic kidney disease (CKD) have high morbidity and mortality, and the disease progression has a significant impact on their survival and living standards. This research aims to analyze risk factors for CKD stage 1 and provide a reference for clinical decision making. The clinical data and peripheral blood samples of 300 patients with CKD stage 1 were collected retrospectively. Patients were randomly assigned into a training set (n = 210) and a validation set (n = 90). Patients’ baseline characteristic levels were subjected to statistical tests for difference. Univariate and multivariate Cox regression analyses were utilized to identify risk factors influencing disease progression. Subsequently, a prediction model for disease progression was developed using a nomogram, and the model’s accuracy was assessed using the C-index and calibration curve. The results revealed that hypertension, diabetes, and urinary albumin were essential factors in the progression of CKD stage 1. The nomogram was constructed and then the C-index was calculated. The calibration curve was utilized to assess the risk model. The C-index of the training set was 0.75, and the C-index of the validation set was 0.73, suggesting a good predictive ability of the model. The risk model accurately predicted the progression of CKD stage 1, which is of great significance to developing personalized treatment for patients in clinical practice.
