Does faster weight trajectory lead to improved neurodevelopmental outcomes in ELBW infants with bronchopulmonary dysplasia?

OBJECTIVE: Examine the relationship between weight trajectory and 2-year neurodevelopmental outcomes for extremely low birthweight (ELBW) infants with BPD. STUDY DESIGN: Secondary analysis of infants born from 2010 to 2019. The predictor was BPD severity and the outcome was neurodevelopmental impairment, defined as any Bayley Scales of Infant Development (BSID) III score <70 at 24 months' corrected age. Repeated measures logistic regression was performed. RESULTS: In total, 5042 infants were included. Faster weight trajectory was significantly associated with a decreased probability of having at least one BSID III score <70 for infants with grade 1-2 BPD (p < 0.0001) and an increased probability of at least one BSID III score <70 for infants with grade 3 BPD (p < 0.009). There was no significant association between weight trajectory and BSID III score <70 for infants with grade 0 BPD. CONCLUSION: The association between postnatal weight trajectory and neurodevelopmental outcome in this study differs by BPD severity.

Increased length of stay and hospital charges in adolescents with type 1 diabetes and psychiatric illness.

OBJECTIVES: Type I diabetes mellitus (T1DM) is one of the most common chronic diseases of childhood. Diabetic ketoacidosis (DKA) in this population contributes to significant healthcare utilization, including emergency room visits, hospitalizations, and ICU care. Comorbid psychiatric illnesses (CPI) are additional risks for increased healthcare utilization. While CPI increased risk for DKA hospitalization and readmission, there are no data evaluating the relationship between CPI and hospital outcomes. We hypothesized that adolescents with T1DM and CPI admitted for DKA have increased length of stay (LOS) and higher charges compared to those without CPI. METHODS: Retrospective review of 2000-2012 Healthcare Cost and Utilization Project's (HCUP) Kids' Inpatient Databases (KID). Patients 10-21 years old admitted with ICD-9 codes for DKA or severe diabetes (250.1-250.33) with and without ICD-9 codes for depression (296-296.99, 311) and anxiety (300-300.9). Comparisons of LOS, mortality, and charges between groups (No CPI, Depression and Anxiety) were made with one way ANOVA with Bonferroni correction, independent samples Kruskal-Wallis test with Bonferroni correction and χ2. RESULTS: There were 79,673 admissions during the study period: 68,573 (86%) No CPI, 8,590 (10.7%) Depression and 12,510 (15.7%) Anxiety. Female patients comprised 58.2% (n=46,343) of total admissions, 66% of the Depression group, and 71% of the Anxiety group. Patients with depression or anxiety were older and had longer LOS and higher mean charges (p<0.001 for both). CONCLUSION: Comorbid depression or anxiety are associated with significantly longer LOS and higher charges in adolescents with T1DM hospitalized for DKA. This study adds to the prior findings of worse outcomes for patients with both T1DM and CPI, emphasizing the importance of identifying and treating these comorbid conditions.

Greater length of stay and hospital charges for severe asthma in children with depression or anxiety.

RATIONALE: Asthma is one of the most common chronic disorders of childhood and is associated with significant healthcare utilization and costs. Comorbid psychiatric illnesses, specifically depression and anxiety, are more prevalent in patients with asthma and associated with worse asthma control, more emergency department visits, and increased hospitalization rates. OBJECTIVES: We aimed to compare hospital outcomes and charges for children with severe asthma with and without comorbid depression and anxiety, hypothesizing that those with depression and anxiety would have longer hospitalizations and higher charges. METHODS: Retrospective review of the 2000-2012 Healthcare Cost and Utilization Project's Kids' Inpatient Databases for admissions of patients aged 10-21 years with an ICD-9 code severe asthma (status asthmaticus or any asthma diagnosis with a procedure code for endotracheal intubation). Depression and Anxiety subgroups were created based on ICD-9 codes. Data collected included demographics, hospital outcomes and charges and comparisons made between groups. RESULTS: There were 52,485 admissions for severe asthma: 45,094 (86%) with No Comorbid Psychiatric Illnesses, 1284 (2.4%) with depression, and 1297 (2.5%) with anxiety. Patients with depression or anxiety were older, had longer hospitalizations, and higher hospital charges (p < .001 for all). CONCLUSIONS: Comorbid depression or anxiety is associated with significantly longer hospitalizations and higher charges for children with severe asthma. These findings add to prior reports of worse outcomes for children with asthma and comorbid depression or anxiety and suggest that improved screening for and management of these conditions in children with asthma could improve hospital outcomes and reduce costs.

Negative impact of waiting time for primary total knee arthroplasty on satisfaction and patient-reported outcome.

PURPOSE: The primary objective of this study was to evaluate the influence of the time on waiting list for total knee arthroplasty (TKA) on the post-operative satisfaction and patient-reported outcomes. METHODS: This was a prospective observational study of 192 patients followed for one year. Patients were pre and post-operatively assessed with the 12-item Short-Form, reduced Western Ontario MacMaster University, and Knee Society scores. In addition, the Hospital Anxiety and Depression scale was used at time of admission, and patient satisfaction on a five point Likert scale at one post-operative year. Univariate and multivariate analyses were performed. RESULTS: Patients waiting longer than six months had significantly worse pre-operative anxiety score as well as post-operative SF12 (both physical and mental) and KSS-function scores compared to those with a waiting time shorter than six months. Dissatisfaction rate was also higher in patients waiting longer than six months, and it was mainly influenced by pre-operative anxiety and depression. CONCLUSIONS: Waiting time longer than six months negatively influenced post-operative satisfaction and patient-related outcome at one year after TKA. These findings may have important clinical implications regarding the prioritization of patients on wait lists or for optimization of treatment while patients wait for surgery related to the management of the mental health and anxiety in order to reduce post-operative dissatisfaction and improve patient-reported outcomes.

Identification of CD3+ T lymphocytes in the green turtle Chelonia mydas.

To understand the role of the immune system with respect to disease in reptiles, there is the need to develop tools to assess the host's immune response. An important tool is the development of molecular markers to identify immune cells, and these are limited for reptiles. We developed a technique for the cryopreservation of peripheral blood mononuclear cells and showed that a commercially available anti-CD3 epsilon chain antibody detects a subpopulation of CD3 positive peripheral blood lymphocytes in the marine turtle Chelonia mydas. In the thymus and in skin inoculated with phytohemagglutinin, the same antibody showed the classical staining pattern observed in mammals and birds. For Western blot, the anti-CD3 antibodies identified a 17.6k Da band in membrane proteins of peripheral blood mononuclear cell compatible in weight to previously described CD3 molecules. This is the first demonstration of CD3+ cells in reptiles using specific antibodies.
