RESUMO

BACKGROUND: The COVID-19 pandemic affected home and work routines, which may exacerbate existing academic professional disparities. Objectives were to describe the impact of the pandemic on pediatric faculty's work productivity, identify groups at risk for widening inequities, and explore mitigation strategies. METHODS: A cross-sectional study of faculty members was conducted at nine U.S. pediatric departments. Responses were analyzed by demographics, academic rank, and change in home caregiving responsibility. RESULTS: Of 5791 pediatric faculty members eligible, 1504 (26%) completed the survey. The majority were female (64%), over 40 years old (60%), and assistant professors (47%). Only 7% faculty identified as underrepresented in medicine. Overall 41% reported an increase in caregiving during the pandemic. When comparing clinical, administrative, research, and teaching activities, faculty reported worse 1-year outlook for research activities. Faculty with increased caregiving responsibilities were more likely to report concerns over delayed promotion and less likely to have a favorable outlook regarding clinical and research efforts. Participants identified preferred strategies to mitigate challenges. CONCLUSIONS: The COVID-19 pandemic negatively impacted pediatric faculty productivity with the greatest effects on those with increased caregiving responsibilities. COVID-19 was particularly disruptive to research outlook. Mitigation strategies are needed to minimize the long-term impacts on academic pediatric careers. IMPACT: The COVID-19 pandemic most negatively impacted work productivity of academic pediatric faculty with caregiving responsibilities. COVID-19 was particularly disruptive to short-term (1-year) research outlook among pediatric faculty. Faculty identified mitigation strategies to minimize the long-term impacts of the pandemic on academic pediatric career pathways.

RESUMO

Objective: To determine if artificial neural networks (ANN) could predict the risk of intra-abdominal abscess (IAA) development post-appendectomy. Background: IAA formation occurs in 13.6% to 14.6% of appendicitis cases with "complicated" appendicitis as the most common cause of IAA. There remains inconsistency in describing the severity of appendicitis with variation in treatment with respect to perforated appendicitis. Methods: Two "reproducible" ANN with different architectures were developed on demographic, clinical, and surgical information from a retrospective surgical dataset of 1574 patients less than 19 years old classified as either negative (n = 1,328) or positive (n = 246) for IAA post-appendectomy for appendicitis. Of 34 independent variables initially, 12 variables with the highest influence on the outcome selected for the final dataset for ANN model training and testing. Results: A total of 1574 patients were used for training and test sets (80%/20% split). Model 1 achieved accuracy of 89.84%, sensitivity of 70%, and specificity of 93.61% on the test set. Model 2 achieved accuracy of 84.13%, sensitivity of 81.63%, and specificity of 84.6%. Conclusions: ANN applied to selected variables can accurately predict patients who will have IAA post-appendectomy. Our reproducible and explainable ANNs potentially represent a state-of-the-art method for optimizing post-appendectomy care.

RESUMO

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first reported in December 2019 in Wuhan, China. This novel coronavirus has been responsible for a pandemic that continues to devastate nations worldwide. COVID-19, like other viruses, causes pneumonia. However, unlike other viral respiratory tract infections such as influenza, bacterial coinfection in COVID-19 patients has uncommonly been described in adult and pediatric patients. We report a case of Streptococcus pneumoniae and COVID-19 coinfection in a previously healthy 4-year-old child.

RESUMO

Pulmonary infection due to Mycobacterium abscessus occurs in patients with cystic fibrosis, but rarely in immunocompetent children without underlying lung pathology. Treatment is complicated by frequent resistance to many antibiotics. We present a case report of a 4-month-old female infant with 2 months of cough, difficulty feeding, and failure to thrive, with extensive culture-confirmed M. abscessus pulmonary infection without identified immunodeficiency or underlying lung pathology following multidisciplinary evaluation. We describe our complete evaluation including immunodeficiency evaluation incorporating whole-exome sequencing, describe our antibiotic selection and treatment duration given complicated susceptibility pattern of the M. abscessus isolate, and review literature for nontuberculous mycobacterial pulmonary disease in immunocompetent children. A complete multidisciplinary evaluation for underlying lung disease and primary and acquired immunodeficiency should be undertaken in pediatric patients with M. abscessus pneumonia. Confirming macrolide susceptibility through erm(41) gene evaluation is clinically important for isolates with complicated susceptibility pattern.

RESUMO

BACKGROUND: Clinical practice guidelines (CPGs) have been associated with improved patient outcomes. We aimed to evaluate institutional CPG adherence and hypothesized that adherence would be associated with fewer complications in pediatric appendicitis. METHODS: A retrospective review was conducted of pediatric (<18 y) appendicitis patients who underwent appendectomy (6/1/2017-5/30/2018). Patients were managed using an institutional pediatric appendicitis CPG. The primary outcome was CPG adherence, defined as receipt of preoperative antibiotics at diagnosis, surgical prophylaxis before incision, and, in perforated/gangrenous appendicitis, continued postoperative antibiotics, and prescription for discharge antibiotics. Univariate and multivariate analyzes were performed. RESULTS: Among 399 patients, the baseline characteristics were similar between CPG-adherent and nonadherent patients. Overall CPG adherence was low at 55% (n = 221). Only 58% of patients received preoperative antibiotics per protocol (n = 233). Patients with simple appendicitis were more likely to proceed to surgery without receiving any preoperative antibiotics (35% vs. 21%, P = 0.004). Surgical prophylaxis compliance was high at 97% (n = 389). CPG violation was associated with reoperation (n = 5 versus 0, P = 0.02). After adjusting for age and admission white blood cell count, the association between CPG adherence and postoperative surgical site infection or intra-abdominal abscess remained nonsignificant (OR: 1.2, 95% CI: 0.5-2.5). CONCLUSIONS: Despite a long-standing pediatric appendicitis CPG, adherence with antibiotic components of the CPG was poor. CPG violation was significantly associated with reoperation, but was not associated with other postoperative complications. Regular audits of CPG adherence are necessary to ascertain reasons for noncompliance and identify ways to improve adherence.

RESUMO

We report a female toddler who presented repetitively with a chief complaint of motile white worms seen in her diapers. Symptoms of perianal itching and visualization of visible motile worms persisted for 6 months despite being treated with multiple courses of albendazole causing a lot of frustration and distress to the caregivers. The characteristics of the worms by inspection along with the presence of 3 pet dogs are consistent with Dipylidium caninum.

RESUMO

We report a cluster of 6 pediatric residents of Houston, Texas, USA, who presented with Plasmodium vivax infection within an eight-week period. All had immigrated to the United States from Afghanistan within the previous year. The clustering raises the possibilities of local mosquito vectored infection and/or synchronous relapses. Molecular typing and local mosquito testing are crucial in delineating the source of similar clusters in nonendemic regions. Single-dose hypnozoite eradication treatment may be considered in emigrating children to malaria nonendemic countries.

RESUMO

A series of naphthalenyl-substituted arenediynes were prepared to examine photochemical reactivity. For naphthalen-1-ylethynyl arenediyne, 350 nm photolysis resulted in a tandem [2 + 2] photocycloaddition to afford cyclobutene adducts. For naphthalen-2-ylethynyl derivatives, electron-donating methoxy substituents were found to facilitate C(1)-C(6) Bergman cyclization at 300 nm. Theoretical calculations provided further insight into thermal and photochemical reactivity.

RESUMO

BACKGROUND: Respiratory Syncytial Virus (RSV) infection is usually restricted to the respiratory epithelium. Few studies have documented the presence of RSV in the systemic circulation, however there is no consistent information whether virus detection in the blood correlates with disease severity. METHODS: Balb/c mice were inoculated with live RSV, heat-inactivated RSV or medium. A subset of RSV-infected mice was treated with anti-RSV antibody 72 h post-inoculation. RSV RNA loads were measured by PCR in peripheral blood from day 1-21 post-inoculation and were correlated with upper and lower respiratory tract viral loads, the systemic cytokine response, lung inflammation and pulmonary function. Immunohistochemical staining was used to define the localization of RSV antigens in the respiratory tract and peripheral blood. RESULTS: RSV RNA loads were detected in peripheral blood from day 1 to 14 post-inoculation, peaked on day 5 and significantly correlated with nasal and lung RSV loads, airway obstruction, and blood CCL2 and CXCL1 expression. Treatment with anti-RSV antibody reduced blood RSV RNA loads and improved airway obstruction. Immunostaining identified RSV antigens in alveolar macrophages and peripheral blood monocytes. CONCLUSIONS: RSV RNA was detected in peripheral blood upon infection with live RSV, followed a time-course parallel to viral loads assessed in the respiratory tract and was significantly correlated with RSV-induced airway disease.

RESUMO

The role of respiratory viruses in the pathogenesis of Kawasaki disease (KD) remains controversial. In this study, we showed that 8.8% of patients with KD had documented respiratory viral infections. Patients with concomitant viral infections had a higher frequency of coronary artery dilatations and were significantly more often diagnosed with incomplete KD. The presence of a concomitant viral infection should not exclude the diagnosis of KD.
