Sustaining Long-term Asthma Outcomes at a Community and Tertiary Care Pediatric Hospital

Hosp Pediatr. 2023 Jan 12:e2021006224. doi: 10.1542/hpeds.2021-006224. Online ahead of print.

ABSTRACT

BACKGROUND AND OBJECTIVES: Implementing asthma Clinical Practice Guidelines (CPG) have been shown to improve length of stay (LOS) and readmission rates on a short-term basis at both tertiary care and community hospital settings. Whether these outcomes are sustained long term is not known. The goal of this study was to measure the long-term impact of CPG implementation at both tertiary and community sites in 1 hospital system.

METHODS: A retrospective study was conducted using the Pediatric Health Information System database. LOS and 7- and 14-day emergency department (ED) revisit and readmission rates from 2009 to 2020 were compared pre and post implementation of asthma CPG in 2012 at both sites. Implementation involved electronic order sets, early metered dose inhaler introduction, and empowering respiratory therapists to wean per the bronchodilator weaning protocol. Interrupted time series and statistical process control charts were used to assess CPG impact.

RESULTS: Implementation of asthma CPG was associated with significant reductions in the variability of LOS without impacting ED revisit or readmission rates at both the tertiary and community sites. Secular trends in the interrupted time series did not demonstrate significant impact of CPG on LOS. However, the overall trend toward decreased LOS that started before CPG implementation was sustained for 7 years after CPG implementation.

CONCLUSIONS: Early metered dose inhaler introduction, respiratory therapist-driven bronchodilator weaning, and electronic order sets at both the community and tertiary care site led to a significant reduction in the variation of LOS, without impacting ED revisit or readmission rate.

Characteristics, ICU Interventions, and Clinical Outcomes of Patients With Palliative Care Triggers in a Mixed Community-Based Intensive Care Unit

J Palliat Care. 2023 Jan 11:8258597221145326. doi: 10.1177/08258597221145326. Online ahead of print.

ABSTRACT

Objective: Integration of palliative care initiatives in the intensive care unit (ICU) benefit patients and improve outcomes. Palliative care triggers (PCTs) is a screening tool that aides in stratifying patients who would benefit most from an early palliative care approach. There is no consensus on PCT selection or best timing for implementation. We evaluated the clinical characteristics, ICU and palliative care interventions, and clinical outcomes of critically ill patients with PCT in a community-based mixed ICU. Methods: This retrospective study was conducted in a 44-bed adult, mixed ICU in a 407-bed community-based teaching hospital in Florida. Eleven PCTs were used as a screening tool during multidisciplinary rounds (MDRs). Patients were analyzed based on presence or absence of PCT as well as having met high (>2) versus low (<2) PCT. Data collected included patient demographics, ICU resource utilization and clinical outcomes. We considered a two-sided P value of less than .05 to indicate statistical significance with a 95% confidence interval. Results: Of 388 ICU patients, 189 (48.7%) met at least 1 PCT and 199 (51.3%) did not. The trigger group had higher Acute Physiology and Chronic Evaluation (APACHE) and Sequential Organ Failure Assessment (SOFA) scores within 24 h of ICU admission. The most common PCTs identified were ICU length of stay greater than 7 days or readmission to ICU, terminal prognosis and assisting family in transitioning goals of care. There were statistically significant differences in ICU resource utilization, palliative care interventions, and overall worse clinical outcomes in the trigger-detected group. Similar findings were seen in the cohort with high PCT (>2). Conclusions: Our study supports the implementation of a tailored 11-item palliative care screening tool to effectively identify ICU patients with high ICU and palliative care interventions and worse clinical outcomes.

Explosive eye injuries: characteristics, traumatic mechanisms, and prognostic factors for poor visual outcomes

Mil Med Res. 2023 Jan 12;10(1):3. doi: 10.1186/s40779-022-00438-4.

ABSTRACT

BACKGROUND: Explosions can produce blast waves, high-speed medium, thermal radiation, and chemical spatter, leading to complex and compound eye injuries. However, few studies have comprehensively investigated the clinical features of different eye injury types or possible risk factors for poor prognosis.

METHODS: We retrospectively reviewed all consecutive records of explosive eye injuries (1449 eyes in 1115 inpatients) in 14 tertiary referral hospitals in China over 12 years (between January 2008 and December 2019). Data on demographics, eye injury types, ocular findings, treatments, and factors affecting visual prognosis were extracted from a standardized database of eye injuries and statistically analyzed.

RESULTS: Mechanical ocular trauma accounted for 94.00% of explosion-related eye injuries, among which intraocular foreign bodies (IOFBs) resulted in 55.17% of open globe injuries (OGIs) and contusion caused 60.22% of close globe injuries (CGIs). Proliferative vitreous retinopathy (PVR) was more common in perforating (47.06%) and IOFB (26.84%) than in penetrating (8.79%) injuries, and more common with laceration (24.25%) than rupture (9.22%, P < 0.01). However, no difference was observed between rupture and contusion. Ultimately, 9.59% of eyes were removed and the final vision was ≤ 4/200 in 45.82% of patients. Poor presenting vision [odds ratio (OR) = 5.789], full-thickness laceration of the eyeball ≥ 5 mm (OR = 3.665), vitreous hemorrhage (OR = 3.474), IOFB (OR = 3.510), non-mechanical eye injury (NMEI, OR = 2.622, P < 0.001), rupture (OR = 2.362), traumatic optic neuropathy (OR = 2.102), retinal detachment (RD, OR = 2.033), endophthalmitis (OR = 3.281, P < 0.01), contusion (OR = 1.679), ciliary body detachment (OR = 6.592), zone III OGI (OR = 1.940), and PVR (OR = 1.615, P < 0.05) were significant negative predictors for poor visual outcomes.

CONCLUSIONS: Explosion ocular trauma has complex mechanisms, with multiple eyes involved and poor prognosis. In lethal level I explosion injuries, eyeball rupture is a serious condition, whereas contusion is more likely to improve. In level II injuries, IOFBs are more harmful than penetrating injuries, and level IV represents burn-related eye injuries. PVR is more associated with penetrating mechanisms than with OGI. Identifying the risk predictors for visual prognosis can guide clinicians in the evaluation and treatment of ocular blast injuries.

Comparison of telemonitoring combined with intensive patient support with standard care in patients with chronic cardiovascular disease – a randomized clinical trial

Eur J Med Res. 2023 Jan 11;28(1):22. doi: 10.1186/s40001-023-00991-1.

ABSTRACT

IMPORTANCE: Healthcare concepts for chronic diseases based on tele-monitoring have become increasingly important during COVID-19 pandemic.

OBJECTIVE: To study the effectiveness of a novel integrated care concept (NICC) that combines tele-monitoring with the support of a call centre in addition to guideline therapy for patients with atrial fibrillation, heart failure, or treatment-resistant hypertension.

DESIGN: A prospective, parallel-group, open-label, randomized, controlled trial.

SETTING: Between December 2017 and August 2019 at the Rostock University Medical Center (Germany).

PARTICIPANTS: Including 960 patients with either atrial fibrillation, heart failure, or treatment-resistant hypertension.

INTERVENTIONS: Patients were randomized to either NICC (n = 478) or standard-of-care (SoC) (n = 482) in a 1:1 ratio. Patients in the NICC group received a combination of tele-monitoring and intensive follow-up and care through a call centre.

MAIN OUTCOMES AND MEASURES: Three primary endpoints were formulated: (1) composite of all-cause mortality, stroke, and myocardial infarction; (2) number of inpatient days; (3) the first plus cardiac decompensation, all measured at 12-months follow-up. Superiority was evaluated using a hierarchical multiple testing strategy for the 3 primary endpoints, where the first step is to test the second primary endpoint (hospitalization) at two-sided 5%-significance level. In case of a non-significant difference between the groups for the rate of hospitalization, the superiority of NICC over SoC is not shown.

RESULTS: The first primary endpoint occurred in 1.5% of NICC and 5.2% of SoC patients (OR: 3.3 [95%CI 1.4-8.3], p = 0.009). The number of inpatient treatment days did not differ significantly between both groups (p = 0.122). The third primary endpoint occurred in 3.6% of NICC and 8.1% of SoC patients (OR: 2.2 [95%CI 1.2-4.2], p = 0.016). Four patients died of all-cause death in the NICC and 23 in the SoC groups (OR: 4.4 [95%CI 1.6-12.6], p = 0.006). Based on the prespecified hierarchical statistical analysis protocol for multiple testing, the trial did not meet its primary outcome measure.

CONCLUSIONS AND RELEVANCE: Among patients with atrial fibrillation, heart failure, or treatment-resistant hypertension, the NICC approach was not superior over SoC, despite a significant reduction in all-cause mortality, stroke, myocardial infarction and cardiac decompensation. Trial registration ClinicalTrials.gov Identifier: NCT03317951.

Systemic interindividual epigenetic variation in humans is associated with transposable elements and under strong genetic control

Genome Biol. 2023 Jan 12;24(1):2. doi: 10.1186/s13059-022-02827-3.

ABSTRACT

BACKGROUND: Genetic variants can modulate phenotypic outcomes via epigenetic intermediates, for example at methylation quantitative trait loci (mQTL). We present the first large-scale assessment of mQTL at human genomic regions selected for interindividual variation in CpG methylation, which we call correlated regions of systemic interindividual variation (CoRSIVs). These can be assayed in blood DNA and do not reflect interindividual variation in cellular composition.

RESULTS: We use target-capture bisulfite sequencing to assess DNA methylation at 4086 CoRSIVs in multiple tissues from each of 188 donors in the NIH Gene-Tissue Expression (GTEx) program. At CoRSIVs, DNA methylation in peripheral blood correlates with methylation and gene expression in internal organs. We also discover unprecedented mQTL at these regions. Genetic influences on CoRSIV methylation are extremely strong (median R2=0.76), cumulatively comprising over 70-fold more human mQTL than detected in the most powerful previous study. Moreover, mQTL beta coefficients at CoRSIVs are highly skewed (i.e., the major allele predicts higher methylation). Both surprising findings are independently validated in a cohort of 47 non-GTEx individuals. Genomic regions flanking CoRSIVs show long-range enrichments for LINE-1 and LTR transposable elements; the skewed beta coefficients may therefore reflect evolutionary selection of genetic variants that promote their methylation and silencing. Analyses of GWAS summary statistics show that mQTL polymorphisms at CoRSIVs are associated with metabolic and other classes of disease.

CONCLUSIONS: A focus on systemic interindividual epigenetic variants, clearly enhanced in mQTL content, should likewise benefit studies attempting to link human epigenetic variation to the risk of disease.

Machine learning in 3D auto-filling alveolar cleft of CT images to assess the influence of alveolar bone grafting on the development of maxilla

BMC Oral Health. 2023 Jan 11;23(1):16. doi: 10.1186/s12903-023-02706-8.

ABSTRACT

BACKGROUND: Machine learning based auto-segmentation of 3D images has been developed rapidly in recent years. However, the application of this new method in the research of patients with unilateral cleft lip and palate (UCLP) is very limited. In this study, a machine learning algorithm utilizing 3D U-net was used to automatically segment the maxilla, fill the cleft and evaluate the alveolar bone graft in UCLP patients. Cleft related factors and the surgery impact on the development of maxilla were analyzed.

METHODS: Preoperative and postoperative computed tomography images of 32 patients (64 images) were obtained. The deep-learning-based protocol was used to segment the maxilla and defect, followed by manual refinement. Paired t-tests and Mann-Whitney tests were performed to reveal the changes of the maxilla after surgery. Two-factor, two-level analysis for repeated measurement was used to examine the different trends of growth on the cleft and non-cleft sides of the maxilla. Pearson and Spearman correlations were used to explore the relationship between the defect and the changes of the maxillary cleft side.

RESULTS: One-year after the alveolar bone grafting surgery, different growth amount was found on the cleft and non-cleft sides of maxilla. The maxillary length (from 34.64 ± 2.48 to 35.67 ± 2.45 mm) and the alveolar length (from 36.58 ± 3.21 to 37.63 ± 2.94 mm) increased significantly only on the cleft side while the maxillary anterior width (from 11.61 ± 1.61 to 12.01 ± 1.41 mm) and posterior width (from 29.63 ± 2.25 to 30.74 ± 2.63 mm) increased significantly only on the non-cleft side after surgery. Morphology of the cleft was found to be related to the pre-surgical maxillary dimension on the cleft side, while its correlation with the change of the maxilla after surgery was low or not statistically significant.

CONCLUSION: The auto-segmentation of the maxilla and the cleft could be performed very efficiently and accurately with the machine learning method. Asymmetric growth was found on the cleft and non-cleft sides of the maxilla after alveolar bone graft in UCLP patients. The morphology of the cleft mainly contributed to the pre-operation variance of the maxilla but had little impact on the maxilla growth after surgery.

Evaluation of a cluster-randomized controlled trial: Communities for Healthy Living, family-centered obesity prevention program for Head Start parents and children

Int J Behav Nutr Phys Act. 2023 Jan 11;20(1):4. doi: 10.1186/s12966-022-01400-2.

ABSTRACT

BACKGROUND: This study reports the outcomes of Communities for Healthy Living (CHL), a cluster randomized obesity prevention trial implemented in partnership with Head Start, a federally-funded preschool program for low-income families.

METHODS: Using a stepped wedge design, Head Start programs (n = 16; Boston, MA, USA) were randomly assigned to one of three intervention start times. CHL involved a media campaign and enhanced nutrition support. Parents were invited to join Parents Connect for Healthy Living (PConnect), a 10-week wellness program. At the beginning and end of each school year (2017-2019), data were collected on the primary outcome of child Body Mass Index z-score (BMIz) and modified BMIz, and secondary outcomes of child weight-related behaviors (diet, physical activity, sleep, media use) and parents’ weight-related parenting practices and empowerment. Data from 2 years, rather than three, were utilized to evaluate CHL due to the COVID-19 pandemic. We used mixed effects linear regression to compare relative differences during intervention vs. control periods (n = 1274 vs. 2476 children) in (1) mean change in child BMIz and modified BMIz, (2) the odds of meeting child health behavior recommendations, (3) mean change in parenting practices, and (4) mean change in parent empowerment. We also compared outcomes among parents who chose post-randomization to participate in PConnect vs. not (n = 55 vs. 443).

RESULTS: During intervention periods (vs. control), children experienced greater increases in BMIz and modified BMIz (b = 0.06, 95% CI = 0.02,0.10; b = 0.07, 95% CI = 0.03, 0.12), yet were more likely to meet recommendations related to three of eight measured behaviors: sugar-sweetened beverage consumption (i.e., rarely consume; Odds Ratio (OR) = 1.5, 95% CI = 1.2,2.3), water consumption (i.e., multiple times per day; OR = 1.6, 95% CI = 1.2,2.3), and screen time (i.e., ≤1 hour/day; OR = 1.4, 95% CI = 1.0,1.8). No statistically significant differences for intervention (vs. control) periods were observed in parent empowerment or parenting practices. However, parents who enrolled in PConnect (vs. not) demonstrated greater increases in empowerment (b = 0.17, 95% CI = 0.04,0.31).

CONCLUSIONS: Interventions that emphasize parent engagement may increase parental empowerment. Intervention exposure was associated with statistically, but not clinically, significant increases in BMIz and increased odds of meeting recommendations for three child behaviors; premature trial suspension may explain mixed results.

The effect of interactions between BMI and sustained depressive symptoms on knee osteoarthritis over 4 years: data from the osteoarthritis initiative

BMC Musculoskelet Disord. 2023 Jan 12;24(1):27. doi: 10.1186/s12891-023-06132-3.

ABSTRACT

BACKGROUND: To assess the compound effects of BMI and sustained depressive symptoms on changes in knee structure, cartilage composition, and knee pain over 4 years using statistical interaction analyses.

METHODS: One thousand eight hundred forty-four individuals from the Osteoarthritis Initiative Database were analyzed at baseline and 4-year follow-up. Individuals were categorized according to their BMI and presence of depressive symptoms (based on the Center for Epidemiological Studies Depression Scale (threshold≥16)) at baseline and 4-year follow-up. 3 T MRI was used to quantify knee cartilage T2 over 4 years, while radiographs were used to assess joint space narrowing (JSN). Mixed effects models examined the effect of BMI-depressive symptoms interactions on outcomes of cartilage T2, JSN, and knee pain over 4-years.

RESULTS: The BMI-depressive symptoms interaction was significantly associated with knee pain (p < 0.001) changes over 4 years, but not with changes in cartilage T2 (p = 0.27). In women, the BMI-depressive symptoms interaction was significantly associated with JSN (p = 0.01). In a group-based analysis, participants with obesity and depression had significantly greater 4-year changes in knee pain (coeff.(obesity + depression vs. no_obesity + no_depression) = 4.09, 95%CI = 3.60-4.58, p < 0.001), JSN (coeff. = 0.60, 95%CI = 0.44-0.77, p < 0.001), and cartilage T2 (coeff. = 1.09, 95%CI = 0.68-1.49, p < 0.001) than participants without depression and normal BMI.

CONCLUSIONS: The compound effects of obesity and depression have greater impact on knee pain and JSN progression compared to what would be expected based on their individual effects.

Morphometric measurement of lumbar pedicle in different regions: a systematic review

J Orthop Surg Res. 2023 Jan 11;18(1):30. doi: 10.1186/s13018-023-03499-w.

ABSTRACT

OBJECTIVE: To collect the data of pedicle width and height in different areas, and to investigate the difference and variation rule of pedicle width and height.

METHODS: Comprehensive search of PubMed, Ovid Medline, and Web of science databases was performed. Collected data were imported into SPSS, and one-way ANOVA test and post hoc test were used to determine whether there were statistical differences in pedicle width and height between the different regions.

RESULTS: Oceania had the largest pedicle width and height, followed by Americans. West Asian had the largest pedicle width in Asia, followed by East and Southeast Asian, and Chinese and South Asian had similar pedicle width. Different from the variation pattern of pedicle width, the pedicle height of Chinese, East and Southeast Asian and West Asian in Asian range is similar, but the pedicle height of South Asian is significantly smaller than the first three, and has statistical significance.

CONCLUSIONS: People in different regions have similar patterns of variation in pedicle width and height even though they belong to different ethnic groups. This phenomenon is particularly prominent and pronounced in populations in geographically close areas, which may be related to inter-ethnic integration due to population movement between adjacent areas. There is a relationship between the morphological characteristics of the human lumbar pedicle and geographical location.

Regional Comparison of Imaging Biomarkers in the Striatum between Early- and Late-onset Alzheimer’s Disease

Exp Neurobiol. 2022 Dec 31;31(6):401-408. doi: 10.5607/en22022.

ABSTRACT

Striatal changes in the pathogenesis of Alzheimer’s disease (AD) is not fully understood yet. We compared structural and functional image differences in the striatum between patients with early onset AD (EOAD) and late onset AD (LOAD) to investigate whether EOAD harbors autosomal dominant AD like imaging findings. The clinical, neuropsychological and neuroimaging biomarkers of 77 probable AD patients and 107 elderly subjects with normal cognition (NC) from the Alzheimer’s Disease Neuroimaging Initiative (ADNI)-2 dataset were analyzed. Enrolled each subject completed a 3-Tesla MRI, baseline 18F-FDG-PET, and baseline 18F-AV-45 (Florbetapir) amyloid PET studies. AD patients were divided into two groups based on the onset age of clinical symptoms (EOAD <65 yrs; LOAD ≥65 yrs). A standardized uptake value ratio of the striatum and subcortical structures was obtained from both amyloid and FDG-PET scans. Structural MR imaging analysis was conducted using a parametric boundary description protocol, SPHARM-PDM. Of the 77 AD patients, 18 were EOAD and 59 were LOAD. Except for age of symptom onset, there were no statistically significant differences between the groups in demographics and detailed neuropsychological test results. 18F-AV-45 amyloid PET showed marked β-amyloid accumulation in the bilateral caudate nucleus and left pallidum in the EOAD group. Intriguingly, the caudate nucleus and putamen showed maintained glucose metabolism in the EOAD group compared to the LOAD group. Our image findings in the striatum of EOAD patients suggest that sporadic EOAD may share some pathophysiological changes noted in autosomal dominant AD.
