The Hard Lessons and Shifting Modeling Trends of COVID-19 Dynamics: Multiresolution Modeling Approach.

The COVID-19 pandemic has placed epidemiologists, modelers, and policy makers at the forefront of the global discussion of how to control the spread of coronavirus. The main challenges confronting modelling approaches include real-time projections of changes in the numbers of cases, hospitalizations, and fatalities, the consequences of public health policy, the understanding of how best to implement varied non-pharmaceutical interventions and potential vaccination strategies, now that vaccines are available for distribution. Here, we: (i) review carefully selected literature on COVID-19 modeling to identify challenges associated with developing appropriate models along with collecting the fine-tuned data, (ii) use the identified challenges to suggest prospective modeling frameworks through which adaptive interventions such as vaccine strategies and the uses of diagnostic tests can be evaluated, and (iii) provide a novel Multiresolution Modeling Framework which constructs a multi-objective optimization problem by considering relevant stakeholders' participatory perspective to carry out epidemic nowcasting and future prediction. Consolidating our understanding of model approaches to COVID-19 will assist policy makers in designing interventions that are not only maximally effective but also economically beneficial.

Re-imagining the physicians' role in the assessment of feeding challenges in children with autism spectrum disorder.

While feeding challenges in autism spectrum disorder (ASD) are prevalent, they continue to pose a significant diagnostic challenge, leading to misdiagnosis and under diagnosis of factors, both contextual and inherent, that may lead to negative health outcomes. Early identification of feeding difficulties in ASD is necessary to minimize negative health outcomes and strained parent-child relationships. Family physicians and paediatricians are positioned to reduce the impact of such disordered feeding behaviours on the child, family, and health care system. Providing clinicians with a conceptual framework to systematically identify factors contributing to the 'feeding challenge' construct will ensure the appropriate intervention is provided. We present the MOBSE conceptual framework, a multidisciplinary lens for assessing feeding challenges in ASD. This will aid in the proper diagnosis of feeding challenges seen in ASD.

Four-Duct Ligation for the Treatment of Sialorrhea in Children.

IMPORTANCE: The 4-duct ligation procedure has appeal for its surgical simplicity and limited invasiveness in the management of pediatric sialorrhea. However, more information is required to understand the benefits, risks, success rates, and long-term effects of this intervention. OBJECTIVES: To report the clinical outcomes of the 4-duct ligation procedure in pediatric patients diagnosed as having sialorrhea and the associated complication rates and to characterize patient and caregiver satisfaction in a consecutive series. DESIGN, SETTING, AND PARTICIPANTS: This investigation was a retrospective cohort study at an academic tertiary pediatric center and pediatric rehabilitation hospital. Patients included 38 children with neurological impairment who underwent a 4-duct salivary gland ligation (parotid and submandibular glands) between January 1, 2004, and July 31, 2012. The dates of the analysis were August 2013 through February 2015. MAIN OUTCOMES AND MEASURES: Posttreatment assessments included duration of effect, severity and frequency of drooling before and after the procedure, patient complications, caregiver satisfaction, caregiver recommendation of the procedure, and caregiver overall assessment of the child's quality of life. Clinical and outcome measures were collected before the procedure, 1 month after the procedure, 1 year after the procedure, and at the most recent follow-up (range, 3-8 years). RESULTS: The study cohort comprised 38 participants. Their median age was 11 years (age range, 5-17 years), and 37% (14 of 38) were female. The mean (SD) duration of effect was 52.6 (20.4) months. Patients with previous sialorrhea management were more likely to demonstrate an improvement in their drooling frequency score at 1 year. Thirteen complications were documented in 12 patients. The most common complications were persistent facial swelling and aspiration pneumonia. Eighty percent (28 of 35) of caregivers reported an improvement in their child's drooling at 1 month, while 69% (25 of 36) and 71% (24 of 34) stated that there was an improvement at the 1-year follow-up and the most recent follow-up, respectively. CONCLUSIONS AND RELEVANCE: The 4-duct ligation procedure offers a simple, effective, and minimally invasive approach to the management of sialorrhea in children.
