Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.

T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).

PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).

PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.

This study compares outcomes of open versus percutaneous tracheostomies in coronavirus disease 2019 patients to guide clinical decision-making based on disease severity.

A retrospective cohort study using the 2020 National Readmissions Database identified 4810 coronavirus disease 2019 patients (International Statistical Classification of Diseases and Related Health Problems 10th Revision code U071) who underwent tracheostomy. Of these, 2061 had open and 2749 had percutaneous tracheostomies. Patient demographics, severity (All Patient Refined-Diagnosis Related Groups) and outcomes (mortality, readmission, complications) were analysed using chi-squared tests, both overall and by severity.

Mortality was higher in the percutaneous group (29.25 per cent) compared to the open group (26.35 per cent) (p = 0.0265). For severe cases (All Patient Refined-Diagnosis Related Groups 3–4), open tracheostomies had significantly lower mortality, readmission and complication rates (p < 0.05).

Open tracheostomies are associated with better outcomes in severe coronavirus disease 2019 cases. Percutaneous tracheostomies are effective in mild cases, but patient selection and procedural planning should consider disease severity. Future research should validate these findings.

This study investigates the seasonal and regional distribution of paediatric laryngomalacia admissions in the United States, hypothesizing higher admission rates in winter and colder regions due to reduced sunlight exposure affecting vitamin D levels.

We analyzed data from the 2016 Kids’ Inpatient Database (KID), focusing on children under three years old. Laryngomalacia cases were identified using International Classification of Diseases and Related Health Problems 10th Revision (ICD-10) code Q31.5. Seasonal and regional differences in admission rates were assessed using Pearson’s chi-squared test, with a significance level of p less than 0.05.

Of 4,512,196 estimated national admissions, 11,638 were due to laryngomalacia. Admissions increased by 10.0 per cent in winter and decreased by 10.9 per cent in summer (p < 0.005). Regionally, admissions were higher in the Midwest/Central (18.6 per cent) and Northeast (9.3 per cent) and lower in the South (7.4 per cent) and West (11.1 per cent) (p < 0.005).

Laryngomalacia admissions are significantly influenced by seasonal and regional factors, likely related to environmental conditions affecting vitamin D synthesis.

This study investigated the influence of socioeconomic factors on the incidence of laryngomalacia in paediatric in-patients.

Data from the 2016 Healthcare Cost and Utilization Project Kid Inpatient Database were analysed. Variables included zip code median income, race and/or ethnicity, primary expected payer and associated International Statistical Classification of Diseases and Related Health Problems 10th Revision codes in admission.

Lower median income zip codes showed a 6.4 per cent increase in laryngomalacia admissions, while higher-income zip codes had an 8.0 per cent decrease. Black patients exhibited a 24.5 per cent increase and Asian or Pacific Islander patients showed a 42.5 per cent decrease in laryngomalacia admissions. Medicaid and other government programme payers had a 22.1 per cent increase, while Medicare, private insurance and self-pay patients had decreases of 35.5, 20.9 and 55.7 per cent, respectively. Laryngomalacia was associated with a number of disease processes from a multitude of organ systems in a statistically significant manor.

Socioeconomic status, race, primary expected payer and co-morbid disease process significantly impact laryngomalacia admissions.

Eustachian tube dysfunction is prevalent in both paediatric and adult populations. Current clinical guidelines recommend observation over topical intranasal corticosteroids for Eustachian tube dysfunction management, which remains controversial. This study aimed to systematically review randomised, controlled trials assessing topical intranasal corticosteroid efficacy in Eustachian tube dysfunction, and analyse effect through tympanometric normalisation.

PubMed, EMBASE, Web of Science and Cochrane Library databases were searched. All randomised, controlled trials assessing intranasal corticosteroids in adult or paediatric Eustachian tube dysfunction patients were included. A meta-analysis of proportions was used to evaluate tympanogram normalisation.

Of 330 results, eight randomised, controlled trials met inclusion criteria and underwent qualitative data synthesis and risk-of-bias analysis. Meta-analysis of tympanometry data from four eligible trials (n = 512 ears) revealed no significant difference in tympanometric normalisation between intranasal corticosteroids and control (odds ratio 1.21, 95% confidence interval 0.65–2.24).

Study results do not strongly support intranasal corticosteroids for Eustachian tube dysfunction. Data were limited, emphasising the need for larger, higher quality, randomised, controlled trials.

Behavioral interventions are a non-pharmacological treatment that shows improvement in the everyday functioning of people with Mild Cognitive Impairment (MCI). Multiple studies have focused on examining factors that can reduce or enhance adherence to behavioral interventions. However, few studies use adherence as a predictor of functional changes. The goal of this study was to analyze the association between adherence, age, and education in factor score changes of participant impairment, participant adjustment, and partner adjustment in a sample of participants with amnestic MCI (aMCI) and their study partners.

We included fifty-two dyads of a person with aMCI and their study partner with intervention data at baseline and 24-week follow-up from the Physical Exercise and Cognitive Engagement Outcomes for Mild Neurocognitive Disorder (PEACEOFMND) study. At baseline, participants were randomized to one of three behavioral interventions: computerized cognitive training (BrainHQ; n=19), yoga (n=15), or wellness education (n=18). Factors were established from a larger clinical sample that used the same measures as PEACEOFMND. The three-factor latent structure was constructed as the following: 1) participant adjustment combined scores of the Center for Epidemiologic Studies Depression Scale (CES-D), Quality of Life in Alzheimer’s Disease (QoL-AD), and Self-Efficacy for managing MCI scales; 2) partner adjustment included study partner’s scores in CES-D, QoLAD and Caregiving Competence and Mastery Components (CCMC) of the Pearlin scales; 3) participant impairment included participant’s scores in E-Cog memory domain, and study partner’s scores in the Functional Activity Questionnaire (FAQ) and Zarit Burden Interview. We calculated factor changes by obtaining the difference between factor scores at follow-up and baseline. Bayesian correlation analysis was performed to investigate the association between age, education, adherence to the combined behavioral interventions, participant adjustment, participant impairment, and partner adjustment.

The Bayesian correlation results showed moderate evidence (BF10=6.8, Pearson’s r=0.38) supporting a positive correlation between adherence and change in participant adjustment. Additionally, there was moderate evidence (BF10=2.18, Pearson’s r=0.32) supporting a positive correlation between change in participant impairment and participant level of education as well as participant age and change in partner adjustment (BF10=2.8, Pearson’s r=0.33).

Bayesian correlations replicated results from previous analysis using a traditional method, showing that increased adherence to combined behavioral interventions is associated with an increase in participant’s quality of life, self-efficacy, and better mood. Thus, commitment to behavioral intervention completion in aMCI participants is related to overall participant adjustment.

Recurrent laryngeal nerve injury leading to vocal cord paralysis is a known complication of cardiothoracic surgery. Its occurrence during interventional catheterisation procedures has been documented in case reports, but there have been no studies to determine an incidence.

To establish the incidence of left recurrent laryngeal nerve injury leading to vocal cord paralysis after left pulmonary artery stenting, patent ductus arteriosus device closure and the combination of the procedures either consecutively or simultaneously.

Members of the Congenital Cardiovascular Interventional Study Consortium were asked to perform a retrospective analysis to identify cases of recurrent laryngeal nerve injury after the aforementioned procedures. Twelve institutions participated in the analysis. They also contributed the total number of each procedure performed at their respective institutions for statistical purposes.

Of the 1337 patients who underwent left pulmonary artery stent placement, six patients (0.45%) had confirmed vocal cord paralysis. 4001 patients underwent patent ductus arteriosus device closure, and two patients (0.05%) developed left vocal cord paralysis. Patients who underwent both left pulmonary artery stent placement and patent ductus arteriosus device closure had the highest incidence of vocal cord paralysis which occurred in 4 of the 26 patients (15.4%). Overall, 92% of affected patients in our study population had resolution of symptoms.

Recurrent laryngeal nerve injury is a rare complication of left pulmonary artery stent placement or patent ductus arteriosus device closure. However, the incidence is highest in patients undergoing both procedures either consecutively or simultaneously. Additional research is necessary to determine contributing factors that might reduce the risk of recurrent laryngeal nerve injury.
