Abstract

OBJECTIVES: At the onset of the coronavirus disease 2019 pandemic, disruptions to pediatric care and training were immediate and significant. We sought to understand the impact of the pandemic on residency training from the perspective of pediatric residents.METHODS: We conducted a cross-sectional survey of categorical pediatric residents at US training programs at the end of the 2019-2020 academic year. This voluntary survey included questions that explored the impact of the coronavirus disease 2019 pandemic on resident training experiences, postresidency employment plans, and attitudes and perceptions. Data were analyzed by using descriptive statistics and mixed-effects regression models. We performed a sensitivity analysis using respondents from programs with a >40% response rate for questions regarding resident attitudes and perceptions.RESULTS: Residents from 127 of 201 training programs (63.2%) completed the survey, with a response rate of 18.9% (1141 of 6032). Respondents reported multiple changes to their training experience including rotation schedule adjustments, clinic cancellations, and an increase in the use of telemedicine. Respondents also reported inconsistent access to personal protective equipment and increased involvement in the care of adult patients. Graduating resident respondents reported concerns related to employment. Respondents also noted a negative impact on their personal wellness.CONCLUSIONS: Responding residents reported that nearly every aspect of their training was impacted by the pandemic. Describing their experiences may help residency program and hospital leaders supplement missed educational experiences, better support residents through the remaining months of the pandemic, and better prepare for extraordinary circumstances in the future.

Abstract

OBJECTIVES: To investigate the impacts of a Relationship-Centered Care (RCC) communication curriculum with coaching on pediatric residents 1) self-reported use of RCC strategies and perspectives, and 2) opportunities to develop adaptive expertise.METHODS: Residents (n=77) completed a 4h RCC training and shared resultant RCC goals with Coaches (n=15). Data included resident surveys and reflections immediately post-training, and resident and coach surveys 6-months later. Reported use of RCC strategies were compared over time with paired t-tests. Qualitative data were analyzed using open coding guided by sensitizing principles from the RCC framework and adaptive expertise.RESULTS: Pediatric residents reported significant increases (p<0.001) in use of 4/9 RCC strategies after 6 months: eliciting all concerns, chunking information, checking for understanding, and teach-back. Resident reflections highlighted shifts in perspective around RCC. Training combined with coaching provided opportunities for residents to develop adaptive expertise through adapting and innovating across settings and contexts.CONCLUSION: Residents had significant increases in reported use of key RCC strategies after a training combined with coaching and demonstrated opportunities to develop adaptive expertise.PRACTICE IMPLICATIONS: Residency programs should include RCC training with an emphasis on the new and challenging strategies and provide opportunities to practice and receive coaching.

Abstract

A term, appropriate-for-gestational-age, male infant born via normal spontaneous vaginal delivery presented at birth with a full-body erythematous, vesiculobullous rash. He was well-appearing with normal vital signs and hypoglycemia that quickly resolved. His father had a history of herpes labialis. His mother had an episode of herpes zoster during pregnancy and a prolonged rupture of membranes that was adequately treated. The patient underwent a sepsis workup, including 2 attempted but unsuccessful lumbar punctures, and was started on broad-spectrum antibiotics and acyclovir, given concerns about bacterial or viral infection. The rash evolved over the course of several days. Subsequent workup, with particular attention to his history and presentation, led to his diagnosis.

Abstract

We conducted case-control and prospective longitudinal studies to examine risk factors and predictors of disease progression for ALS. Ninety-five subjects with ALS and 106 healthy control subjects were enrolled. All subjects completed a risk factor questionnaire at enrollment. The ALS subjects were prospectively followed for one year to define factors that influence the rate of disease progression, measured by rate of change in percent predicted forced vital capacity (%FVC) and the ALS functional rating scale (ALSFRS) score. The association of each potential risk factor with ALS was determined using univariate logistic regression. A random slope model was used to determine the association of each risk factor with disease progression. The demographic characteristics of ALS subjects and controls at enrollment did not differ. Significant risk factors for ALS included reported exposure to lead (p = 0.02) and pesticides (p = 0.03). Disease progression was faster in the ALS subjects having bulbar onset and a shorter time period between onset of symptoms and diagnosis. Pertinent variables not associated with either causation or progression of ALS included physical activity, cigarette smoking and a history of physical trauma or other clinical disorders.

Abstract

Matrix metalloproteinases (MMPs) may play a role in the pathophysiology of Alzheimer's disease (AD). MMP-9 and tissue inhibitors of metalloproteinases (TIMPs) are elevated in postmortem brain tissue of AD patients. MMPs and TIMPs are found in neurons, microglia, vascular endothelial cells and leukocytes. The aim of this study was to determine whether circulating levels of MMP-2, MMP-9, TIMP-1 and TIMP-2 are elevated in the plasma of AD patients. We compared AD patients to age- and gender-matched controls as well as to Parkinson's disease (PD) and amyotrophic lateral sclerosis (ALS) patients. There was constitutive expression of gelatinase A (MMP-2), and gelatinase B (MMP-9), in all the samples as shown by zymographic analysis. Levels of MMP-9 were significantly (P=0.003) elevated in the plasma of AD patients as compared to controls. Plasma levels of MMP-2, TIMP-1 and TIMP-2 were unchanged. There were no significant changes of MMP-2, MMP-9, TIMP-1 and TIMP-2 levels in PD and ALS samples. TIMP-1 and TIMP-2 were significantly correlated with MMP-9 in the AD patients. ApoE genotyping of plasma samples showed that levels of MMP-2, TIMP-1 and TIMP-2 and MMP-9 were not significantly different between the ApoE subgroups. These findings indicate that circulating levels of MMP-9 are increased in AD and may contribute to disease pathology.

Abstract

Matrix metalloproteinases (MMPs) are implicated in the pathogenesis of diseases such as Alzheimer's Disease (AD) and amyotrophic lateral sclerosis (ALS). Increased expression of MMP-9 and TIMPs has been reported in postmortem AD and ALS brain tissue, as well as in ALS cerebrospinal fluid (CSF) and plasma. Although individual studies of MMP and TIMP expression in CSF have included AD and ALS samples, there are no studies comparing the expression of these proteins between neurodegenerative diseases. We measured the levels of matrix metalloproteinases (MMPs)-2 and -9 and the tissue inhibitor of MMPs (e.g. TIMP-1 and TIMP-2) in CSF samples from patients with Parkinson's Disease (PD), Huntington's Disease (HD), AD and ALS as compared to age-matched control patients. There was constitutive expression of the proform of gelatinase A (proMMP-2) on zymography gels in all CSF samples. Unexpectedly, there was an additional gelatinolytic band at 130 kDa of unknown etiology in the CSF samples of patients with PD (61% of patients studied), AD (61%), HD (25%) and ALS (39%). Levels of TIMP-1 were significantly elevated in CSF samples from all disease groups. TIMP-2 was significantly increased in CSF of AD and HD patients. MMP-2 levels did not differ significantly between groups. These findings show that TIMPs are elevated in the CSF of patients with neurodegenerative diseases suggesting a potential role of these endogenous inhibitors of matrix metalloproteinases in neurodegenerative diseases.
