AbstractBoth deviation and excessive width of the nasal dorsum result in conspicuous facial disharmony and are often attended by nasal airway dysfunction. Whether the result of developmental growth disturbances, nasal trauma, failed nasal surgery, or combinations therein, deviation and splaying of the nasal dorsum can be exceedingly difficult to treat. Individualized treatment is paramount because contour variations are seemingly endless, and a careful preoperative assessment of the anatomic, physiologic, cosmetic, and psychosocial factors that characterize the deformity is necessary to devise an effective patient-specific treatment plan. Ensuring the linearity, strength, alignment, and aesthetically pleasing profile dimensions of the nasal L-strut is the requisite first step in successful treatment. Releasing all deformed components in a controlled and precise manner using powered instrumentation (whenever possible) to facilitate minimally traumatic and effective repositioning, followed by structural reconstitution of the skeletal framework using autologous graft materials, and then consolidation of the newly created construct with suture fixation completes the transformation to normalcy. Paying equal attention to both cosmetic and functional wellness, while simultaneously seeking to maximize structural stability, serves to optimize the final outcome.

Abstract Intracoronary thrombus from plaque erosion could cause fatal acute coronary syndrome (ACS). A conservative anti-thrombotic therapy has been proposed to treat ACS patients in lieu of stenting. It is speculated that the residual thrombus after aspiration thrombectomy would influence the prognosis of this treatment. However, biomechanical mechanisms affecting intracoronary thrombus remodeling and clinical outcome remain largely unknown. In vivo optical coherence tomography (OCT) data of a coronary plaque with two residual thrombi after anti-thrombotic therapy were acquired from an ACS patient with consent obtained. Three OCT-based FSI models with different thrombus volumes, fluid-only and structure-only models were constructed to simulate and compare the biomechanical interplay among blood flow, residual thrombus and vessel wall mimicking different clinical situations. Our results showed that residual thrombus would decrease coronary volumetric flow rate by 9.3%, but elevate wall shear stress (WSS) by 29.4% and 75.5% at Thrombus 1 & 2, respectively. WSS variations in a cardiac cycle from structure-only model were 12.1% and 13.5% higher at the two thrombus surfaces than those from FSI model. Intracoronary thrombi were subjected to compressive forces indicated by negative thrombus stress. Tandem intracoronary thrombus might influence coronary hemodynamics and solid mechanics differently. Computational modeling could be used to quantify biomechanical conditions under which patients could receive patient-specific treatment plan with optimized outcome after anti-thrombotic therapy. More patient studies with follow-up data are needed to continue the investigation and better understand mechanisms governing thrombus remodeling process.

Advanced pancreatic ductal adenocarcinoma represents one of the most challenging oncologic diseases nowadays for many reasons: it is burdened by one of the poorest prognoses, it is often diagnosed when in an advanced stage and it demands a multimodal approach which is necessary to assign the proper patient-specific treatment. When feasible, surgical resection combined with systemic treatment is still the best curative choice and can require complex vascular resections and reconstructions to obtain R0 margins. In these cases, a detailed preoperative assessment made of blood tests, thoracoabdominal imaging and histological definition of the tumor is fundamental. Unfortunately, the current imaging techniques are not completely reliable in defining the extension of the contact between the neoplasm and the surrounding arteries and veins, especially when considering borderline and locally advanced diseases. The use of 3D reconstructions can improve the perception of crucial anatomical details for the diagnostic evaluation and the surgical procedure.

Shock states have multiple etiologies, but all result in hypoperfusion to vital organs, which can lead to organ failure and death if not quickly and appropriately managed. Pharmacists should be familiar with cardiogenic, distributive, and hypovolemic shock and should be involved in providing safe and effective medical therapies. An accurate diagnosis is necessary to initiate appropriate lifesaving interventions and target therapeutic goals specific to the type of shock. Clinical signs and symptoms, as well as hemodynamic data, help with initial assessment and continued monitoring to provide adequate support for the patient. It is necessary to understand these hemodynamic parameters, medication mechanisms of action, and available mechanical support when developing a patient-specific treatment plan. Rapid therapeutic intervention has been proven to decrease morbidity and mortality and is crucial to providing the best patient outcomes. Pharmacists can provide their expertise in medication selection, titration, monitoring, and dose adjustment in these critically ill patients. This review will focus on parameters used to assess hemodynamic status, the major causes of shock, pathophysiologic factors that cause shock, and therapeutic interventions that should be employed to improve patient outcomes.

816 Background: Multidisciplinary tumor boards at Academic Medical Centers (AMC) maximize cancer outcomes. Guidelines based CDSS are alternatives to determine care pathways. Since 2015, 300 AMC cancer experts in USA and India use an AI enabled online tumor board solution, “NAVYA,” to scale low cost access to multidisciplinary expertise, on 1-2 minutes of expert time per decision (ASCO 2017). Methods: GI patients who used NAVYA between 5/1/15-8/31/19 were analyzed. Actionable treatment plans generated by NAVYA were compared to NCCN. Actionable treatment plans include chemotherapy protocols (doses, frequencies), radiation protocols (sites, fractions), etc. Inactionable specialty level decisions (CT-RT vs. surgery) lack specificity. Results: 1302 patients (4638 treatment decisions) were analyzed: 61% (794) male, 80% between age 45 to 75, mostly with Colon, Pancreas, Gallbladder, Rectum, or Stomach cancer; 49.7% non-metastatic. Cohort was comparable to GLOBOCAN estimates. In 82.2% (3812/4638) decisions, NAVYA added value beyond NCCN. First, in 4.5% (212/4638), NAVYA recommended a patient-specific treatment plan that was not part of NCCN. Second, in 3.2% (148/4638), NAVYA recommended treatments plan for clinical scenarios not covered by NCCN, (for eg. 3rd line therapies). Third, in 74.5% (3452/4638), NAVYA used patient specific criteria including resource constraints and patient preference to choose a treatment plan amongst the multiple pathways provided by NCCN and added actionable treatment details. Conclusions: Guideline based CDSS are insufficient to make the vast majority of actionable treatment decisions. Scaling rapid access to multidisciplinary experts is critical. Leapfrogging existing guidelines based CDSS, NAVYA online tumor board makes actionable expert treatment plans possible at a large scale.

Objective: To investigate intrinsic palatal and alveolar tissue deficiency in patients with unilateral cleft lip and palate (UCLP) as compared to age-matched individuals without UCLP using surface area measurements on 3D scans of plaster casts. Methods: 22 maxillary casts of infants with UCLP from the Wyss Department of Plastic Surgery of NYU Langone Medical Center and 37 maxillary casts from infants without clefts from Sillman’s longitudinal study were scanned by Ortho Insight 3D by Motion View Software, LLC (Chattanooga, TN) and measured using Checkpoint software (Stratovan, Davis, CA). The palatal and alveolar surface areas of each cast were measured. The most superior point of the alveolar ridge in front of the incisive papilla and the most superior point of each maxillary tuberosity were connected by a line that ran along the highest part of the alveolar ridge. This line was used to set boundaries for the palatal surface area measurements. The surface areas of greater and lesser segments were measured independently on UCLP casts. A total palatal surface area for the UCLP sample including width of the cleft gap was also measured. Results: There was a statistically significant difference in surface area ( P > .001) when we compared the UCLP area of the cleft segments alone with the non-cleft sample. There was a positive correlation (determine the statistical significance) between the surface area of the cleft segments and cleft gap. In addition, there was a statistically significant difference between UCLP plus cleft area and the non-cleft samples in surface area ( P < .0001). Conclusion: An intrinsic palatal and alveolar tissue deficiency exists in patients born with UCLP. The amount of tissue deficiency for a patient with UCLP should be considered when developing and executing a patient-specific treatment plan.

Purpose COVID-19 has shifted models of health care delivery, requiring the rapid adoption of telehealth, despite limited evidence and few resources to guide speech-language pathologists. Management of dysarthria presents specific challenges in the telehealth modality. Evaluations of dysarthria typically rely heavily on perceptual judgments, which are difficult to obtain via telehealth given a variety of technological factors such as inconsistencies in mouth-to-microphone distance, changes to acoustic properties based on device settings, and possible interruptions in connection that may cause video freezing. These factors limit the validity, reliability, and clinicians' certainty of perceptual speech ratings via telehealth. Thus, objective measures to supplement the assessment of dysarthria are essential. Method This tutorial outlines how to obtain objective measures in real time and from recordings of motor speech evaluations to support traditional perceptual ratings in telehealth evaluations of dysarthria. Objective measures include pause patterns, utterance length, speech rate, diadochokinetic rates, and overall speech severity. We demonstrate, through clinical case vignettes, how these measures were completed following three clinical telehealth evaluations of dysarthria conducted via Zoom during the COVID-19 pandemic. This tutorial describes how each of these objective measures were utilized, in combination with subjective perceptual analysis, to determine deviant speech characteristics and their etiology, develop a patient-specific treatment plan, and track change over time. Conclusion Utilizing objective measures as an adjunct to perceptual ratings for telehealth dysarthria evaluations is feasible under real-world pandemic conditions and can be used to enhance the quality and utility of these evaluations.
