ABSTRACT

IMPORTANCE: The prescribing of stimulant medications for attention-deficit/hyperactivity disorder (ADHD) has increased in the US. Prescription stimulants are one of the most commonly misused controlled substances during adolescence. Despite a 10-fold increase in stimulant-related overdose deaths in the past decade, the transitions from prescription stimulants to illicit stimulants (eg, cocaine, methamphetamine) remain relatively unknown in longitudinal population-based studies.

OBJECTIVE: To determine the longitudinal transitions from adolescents’ prescription stimulant exposure (ie, stimulant therapy for ADHD and prescription stimulant misuse [PSM]) to later cocaine and methamphetamine use during young adulthood.

DESIGN, SETTING, AND PARTICIPANTS: National longitudinal multicohort panels of US 12th grade public and private school students in the coterminous US were assessed annually (baseline cohort years 2005-2017 [between March and June]) and followed up across 3 waves over a 6-year period to 23 to 24 years of age (follow-up years 2011-2021 [between April and October]).

EXPOSURE: History of self-reported stimulant therapy for ADHD at baseline.

MAIN OUTCOMES AND MEASURES: Incidence and prevalence of past-year use of cocaine and methamphetamine during young adulthood (19-24 years of age).

RESULTS: Among 5034 students enrolled at baseline (2589 [52.0%] female), 470 (10.2% [95% CI, 9.4%-11.2%]) reported use of stimulant therapy for ADHD, 671 (14.6% [95% CI, 13.5%-15.6%]) reported PSM only, and 3459 (75.2% [95% CI, 73.9%-76.4%]) reported neither (and served as population controls). In controlled analyses, there were no statistically significant differences between adolescents who reported stimulant therapy for ADHD at baseline compared with population controls in the adjusted odds of transitioning to later cocaine or methamphetamine initiation or use during young adulthood (19-24 years of age). In contrast, PSM during adolescence in those not treated with stimulants for ADHD had significantly higher odds of transitioning to later cocaine or methamphetamine initiation and use during young adulthood compared with population controls (adjusted odds ratio, 2.64 [95% CI, 1.54-4.55]).

CONCLUSIONS AND RELEVANCE: In this multicohort study, adolescents’ stimulant therapy for ADHD was not associated with increased risk of later cocaine and methamphetamine use during young adulthood. Adolescents’ prescription stimulant misuse offered a signal for subsequent cocaine or methamphetamine use and warrants monitoring and screening.

ABSTRACT

IMPORTANCE: Numerous studies have shown that the prevalence of mental health (MH) conditions worsened during the COVID-19 pandemic. Further research is needed on this phenomenon over a longer time horizon that considers the increasing trend in MH conditions before the pandemic, after the pandemic onset, and after vaccine availability in 2021.

OBJECTIVE: To track how patients sought help in emergency departments (EDs) for non-MH and MH conditions during the pandemic.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study used administrative data on weekly ED visits and a subset of visits for MH from the National Syndromic Surveillance Program from January 1, 2019, to December 31, 2021. Data were reported from the 10 US Department of Health and Human Services (HHS) regions (Boston, New York, Philadelphia, Atlanta, Chicago, Dallas, Kansas City, Denver, San Francisco, and Seattle) for five 11-week periods. Data analysis was performed in April 2023.

MAIN OUTCOMES AND MEASURES: Weekly trends in total ED visits, mean MH-related ED visits, and proportion of ED visits for MH conditions were investigated to determine changes in each measure after the pandemic onset. Prepandemic baseline levels were established from 2019 data, and time trends of these patterns were examined in the corresponding weeks of 2020 and 2021. A fixed-effects estimation approach with weekly ED region data by year was used.

RESULTS: There were 1570 total observations in this study (52 weeks in 2019, 53 weeks in 2020, and 52 weeks in 2021). Statistically significant changes in non-MH and MH-related ED visits were observed across the 10 HHS regions. The mean total number of ED visits decreased by 45 117 (95% CI, -67 499 to -22 735) visits per region per week (39% decrease; P = .003) in the weeks after the pandemic onset compared with corresponding weeks in 2019. The mean number of ED visits for MH conditions (-1938 [95% CI, -2889 to -987]; P = .003) decreased significantly less (23% decrease) than the mean number of total visits after the onset of the pandemic, increasing the mean (SD) proportion of MH-related ED visits from 8% (1%) in 2019 to 9% (2%) in 2020. In 2021, the mean (SD) proportion decreased to 7% (2%), and the mean number of total ED visits rebounded more than that of mean MH-related ED visits.

CONCLUSIONS AND RELEVANCE: In this study, MH-related ED visits demonstrated less elasticity than non-MH visits during the pandemic. These findings highlight the importance of addressing the provision of adequate MH services, both in acute and outpatient settings.

ABSTRACT

INTRODUCTION: Road traffic injuries are a significant issue for society in the twenty-first century, but public health experts frequently ignore them despite the fact that massive and coor-dinated efforts are required for their effective and long-term prevention. Human factors and poor driving performance are the most significant contributors to car accidents globally, as shown by a series of studies exploring the causes of traffic road accidents. Since road safety is a key concern in developing countries, our research focuses on the car driver behavioral risk factors in the Republic of Moldova.

MATERIAL AND METHODS: A cross-sectional quantitative descriptive using a questionnaire was applied online via a Google form document among car drivers, between January-March 2022. Microsoft Excel was used for the statistical analyses.

RESULTS: The questionnaire was completed by 257 respondents above 18 years, of which 61.9% were female and 38.1% were male, mostly with a category B license (73.5%) and majority from urban area (87.5%). More than half (55.6%) mention that drove a car daily and 30% of them have a drive experience of more than ten years. Respondents express great concern (71.2%) about the issue of traffic accidents, and 76.3% think that unsafe roads are a key contributing factor. At least once being involved as a driver in road accidents where medical care was needed was mentioned by 2.7% of respondents.

CONCLUSIONS: Educational programs and awareness campaigns about road safety among drivers and other vulnerable road users should be systematically organized.

ABSTRACT

In our study, we aimed to create an inflammation model in endothelial and macrophage cell lines and to examine the changes in the expression of hyperpolarization activated cyclic nucleotide gated (HCN) channels at the molecular level. HUVEC and RAW cell lines were used in our study. 1 µg/mL LPS was applied to the cells. Cell media were taken 6 h later. TNF-α, IL-1, IL-2, IL-4, IL-10 concentrations were measured by ELISA method. Cell media were cross-applied to cells for 24 h after LPS. HCN1/HCN2 protein levels were determined by Western-Blot method. HCN-1/HCN-2 gene expressions were determined by qRT-PCR method. In the inflammation model, a significant increase in TNF-α, IL-1, and IL-2 levels was observed in RAW cell media compared to the control. While no significant difference was observed in IL-4 level, a significant decrease was observed in IL-10 level. While a significant increase in TNF-α level was observed in HUVEC cell medium, no difference was observed in other cytokines. In our inflammation model, an 8.44-fold increase in HCN1 gene expression was observed in HUVEC cells compared to the control group. No significant change was observed in HCN2 gene expression. 6.71-fold increase in HCN1 gene expression was observed in RAW cells compared to the control. The change in HCN2 expression was not statistically significant. In the Western-Blot analysis, a statistically significant increase in HCN1 level was observed in the LPS group in HUVEC cells compared to the control; no significant increase in HCN2 level was observed. While a statistically significant increase in HCN1 level was observed in the LPS group in RAW cells compared to the control; no significant increase in HCN2 level was observed. In immunofluorescence examination, it was observed that the level of HCN1 and HCN2 proteins in the cell membrane of HUVEC and RAW cells increased in the LPS group compared to the control group. While HCN1 gene/protein levels were increased in RAW and HUVEC cells in the inflammation model, no significant change was observed in HCN2 gene/protein levels. Our data suggest that the HCN1 subtype is dominant in endothelium and macrophages and may play a critical role in inflammation.

ABSTRACT

PURPOSE: Vertebral body tethering (VBT) is a recent procedure to correct and reduce spinal curves in skeletally immature patients with adolescent idiopathic scoliosis (AIS). The purpose of this systematic review and meta-analysis is to determine the expected curve reduction and potential complications for adolescent patients after VBT.

METHODS: PubMed, Embase, Google Scholar and Cochrane databases were searched until February 2022. Records were screened against pre-defined inclusion and exclusion criteria. Data sources were prospective and retrospective studies. Demographics, mean differences in Cobb angle, surgical details and complication rates were recorded. Meta-analysis was conducted using a random-effects model.

RESULTS: This systematic review includes 19 studies, and the meta-analysis includes 16 of these. VBT displayed a statistically significant reduction in Cobb angle from pre-operative to final (minimum 2 years) measurements. The initial mean Cobb angle was 47.8° (CI 95% 42.9-52.7°) and decreased to 22.2° (CI 95% 19.9-24.5°). The mean difference is – 25.8° (CI 95% – 28.9-22.7) (p < 0.01). The overall complication rate was 23% (CI 95% 14.4-31.6%), the most common complication was tether breakage 21.9% (CI 95% 10.6-33.1%). The spinal fusion rate was 7.2% (CI 95% 2.3-12.1%).

CONCLUSION: VBT results in a significant reduction of AIS at 2 years of follow-up. Overall complication rate was relatively high although the consequences of the complications are unknown. Further research is required to explore the reasons behind the complication rate and determine the optimal timing for the procedure. VBT remains a promising new procedure that is effective at reducing scoliotic curves and preventing spinal fusion in the majority of patients.

ABSTRACT

Single-port (SP) robot-assisted laparoscopic partial nephrectomy (RAPN) is a promising new technique. The aim of this study was to compare surgical and oncological outcomes of SP-RAPN to the multi-port (MP) surgical platform. This is a retrospective, cohort-based study involving patients undergoing SP-RAPN between 2019 and 2020 at a single institution. Demographic, preoperative, surgical, and postoperative outcomes data were gathered and compared to a 1-to-1 matched MP cohort. A total of 50 SP and 50 matched MP cases were included. Length of surgery and ischemia time were not statistically significant between the two cohorts; however, estimated blood loss (EBL) was significantly lower in the SP group than in the MP (IQR 25-50 vs. IQR 50-100 mL, p = 0.002). No differences were seen in regard to the 30-day readmission rate, surgical margin status, pain scores, and complications between the two approaches. We found no statistically significant differences in positive margins, pain score, length of stay, or readmission rate between matched SP and MP patients. These data support the viability of the SP technique as an alternative to MP-RAPN when in the hands of experienced surgeons.

ABSTRACT

INTRODUCTION: We have developed the Building, Relating, Assessing, and Validating Outcomes (BRAVO) diabetes model, an individual-level, discrete-time microsimulation model specifically designed for type 2 diabetes (T2D) management. This study aims to validate the model’s performance when populated exclusively with a fully de-identified dataset to ensure its applicability in secure settings.

METHODS: Patient-level data from the Exenatide Study of Cardiovascular Event Lowering (EXSCEL) trial were fully de-identified by removing all identifiable information and masking numerical values (e.g., age, body mass index) within ranges to minimize the risk of re-identification. To populate the simulation, we imputed the masked numerical values using data from the National Health and Nutrition Examination Survey (NHANES). We applied the BRAVO model to the baseline data to predict 7-year study outcomes for the EXSCEL trial and assessed its discrimination power and calibration using C-statistics and Brier scores.

RESULTS: The model demonstrated acceptable discrimination and calibration in predicting the first occurrence of non-fatal myocardial infarction, non-fatal stroke, heart failure, revascularization, and all-cause mortality. Even with the fully deidentified data from the EXSCEL trial primarily presented in ranges rather than specific values, the BRAVO model exhibited robust prediction performance for diabetes complications and mortality.

CONCLUSIONS: This study demonstrates the feasibility of using the BRAVO model in settings where only fully de-identified patient-level data are available.

ABSTRACT

BACKGROUND: Angiotensin II type-1 receptor antibody (AT1R-Ab) has been associated with vascular injury and kidney dysfunction in pediatric kidney transplant recipients. The role of AT1R-Ab in the development of chronic kidney disease in pediatric liver and intestinal transplant recipients has not been explored.

METHODS: Twenty-five pediatric intestinal transplant recipients and 79 pediatric liver transplant recipients had AT1R-Ab levels measured at varying time points in the post-transplant period. Estimated glomerular filtration rate (eGFR) was determined using creatinine based CKiD U25 equation and measured at time of AT1R-Ab measurement, at 1 year post-AT1R-Ab measurement, at 5 years post-AT1R-Ab measurement, and at the most recent routine clinic visit. The prevalence of hypertension and antihypertensive medication use were also evaluated.

RESULTS: Younger age at time of AT1R-Ab measurement was associated with AT1R-Ab positivity in liver transplant recipients. There was no association between AT1R-Ab status and change in eGFR, prevalence of hypertension, or use of antihypertensive medications at the described time points.

CONCLUSIONS: AT1R-Ab positivity was not associated with a decline in eGFR or hypertension in pediatric liver and intestinal transplant recipients. Further studies are needed using other markers of kidney function, such as cystatin C, to validate this finding. A higher resolution version of the Graphical abstract is available as Supplementary information.

ABSTRACT

PURPOSE: This study aimed to assess our bowel management program (BMP) and identify predictive factors for bowel control in patients with Spina Bifida (SB) and Spinal Cord Injuries (SCI). Additionally, in patients with SB, we examined the impact of fetal repair (FRG) on bowel control.

METHODS: We included all patients with SB and SCI seen in the Multidisciplinary Spinal Defects Clinic at Children’s Hospital Colorado from 2020 to 2023.

RESULTS: 336 patients included. Fecal incontinence was present in 70% and bowel control in 30%. All patients with urinary control also had bowel control. Fecal incontinence prevalence was higher in patients with ventriculoperitoneal (VP) shunt (84%), urinary incontinence (82%), and wheelchair users (79%) compared to those who did not need a VP shunt (56%), had urinary continence (0%) and non-wheelchair users (52%), respectively (p = < 0.001 in all three scenarios). After completing BMP, 90% remained clean for stool. There was no statistical significance when comparing bowel control in FRG with non-fetal repair group.

CONCLUSIONS: Urinary continence predicts bowel control in patients with SB and SCI. Risk factors for fecal incontinence were the need for a VP shunt, urinary incontinence, and wheelchair usage. We did not find any positive impact of fetal repair on bowel and urinary control.

ABSTRACT

Calcinosis is a sequela of Juvenile Dermatomyositis (JDM) with significant morbidity. A retrospective study observing risk factors for JDM calcinosis, including a possible association between higher intensity of subcutaneous and myofascial edema in initial magnetic resonance imaging (MRI) and development of calcinosis was performed at a tertiary pediatric medical center. Data from the past 20 years on JDM patients with MRIs at the time of JDM diagnosis were obtained. MRIs were individually evaluated by two pediatric musculoskeletal radiologists who blindly graded the intensity of edema on a 0-4 Likert scale. Clinical data and edema scores were compared between patients who developed calcinosis and who did not. Forty-three patients (14 with calcinosis and 29 without calcinosis) were identified. The calcinosis group contained more racial and ethnic minorities, younger ages of JDM onset and longer time to reach JDM diagnosis. Muscle enzyme levels at JDM diagnosis were lower in the calcinosis group, especially Creatinine Kinase (CK) (p = 0.047) and Alanine Aminotransferase (ALT) (p = 0.015). The median score for edema in both groups was 3 (p = 0.39) with an inter-rater reliability of 95%. There was no association between increased subcutaneous and myofascial edema in MRIs at the time of JDM diagnosis and development of calcinosis. Earlier age of JDM onset, racial and ethnic minority, and delay in JDM diagnosis could be risks for developing calcinosis. The calcinosis group presented with lower muscle enzyme levels at the time of JDM diagnosis, especially CK and ALT with statistical significance. This could reflect delay in diagnosis and treatment.
