Several models have been proposed to describe the glucose system at whole-body, organ/tissue and cellular level, designed to measure non-accessible parameters (minimal models), to simulate system behavior and run in silico clinical trials (maximal models). Here, we will review the authors' work, by putting it into a concise historical background. We will discuss first the parametric portrait provided by the oral minimal models-building on the classical intravenous glucose tolerance test minimal models-to measure otherwise non-accessible key parameters like insulin sensitivity and beta-cell responsivity from a physiological oral test, the mixed meal or the oral glucose tolerance tests, and what can be gained by adding a tracer to the oral glucose dose. These models were used in various pathophysiological studies, which we will briefly review. A deeper understanding of insulin sensitivity can be gained by measuring insulin action in the skeletal muscle. AZD2014 mTOR inhibitor This requires the use of isotopic tracers both the classicmulators. In particular, the UVA/Padova Type 1 simulator proved to be a very useful tool to safely and effectively test in silico closed-loop control algorithms for an artificial pancreas (AP). This was the first and unique simulator of the glucose system accepted by the U.S. Food and Drug Administration as a substitute to animal trials for in silico testing AP algorithms. Recent uses of the simulator have looked at glucose sensors for non-adjunctive use and new insulin molecules.Background The CAVA (Ultrasound-Accelerated Catheter-Directed Thrombolysis Versus Anticoagulation for the Prevention of Post-Thrombotic Syndrome) trial did not show a reduction of post-thrombotic syndrome (PTS) after additional ultrasound-accelerated catheter-directed thrombolysis in patients with acute iliofemoral deep vein thrombosis at 1-year follow-up. This prespecified analysis of the CAVA trial aimed to determine the impact of additional thrombolysis on outcomes of PTS at long-term follow-up. Methods and Results Patients aged 18 to 85 years with a first-time acute iliofemoral deep vein thrombosis were included and randomly assigned (11) to either standard treatment plus ultrasound-accelerated catheter-directed thrombolysis or standard treatment alone. The primary outcome was the proportion of PTS (Villalta score ≥5 on 2 occasions ≥3 months apart or venous ulceration) at the final follow-up visit. Additionally, PTS according to the International Society on Thrombosis and Haemostasis (ISTH) consensus defiings indicate a reduction of mild PTS without impact on quality of life.

Sinocutaneous fistulae (SCF) are abnormal communications between the paranasal sinuses and the overlying skin. They may be difficult to manage due to facial geometry, scar contraction, and poor tissue vascularity. We describe a novel use of the buccal flap and review the literature to examine management options for this disease process.

A PubMed/MEDLINE literature search was performed for studies published between January 1, 1950 and April 29, 2020 that describe management strategies for SCF. The clinical record, imaging, and operative reports were reviewed of the case in which the buccal fat flap was used in reconstruction.

A total of 359 articles were retrieved. After removing duplicate articles, non-English studies, animal studies, duplicate articles and studies that mentioned SCF without specific mention of management strategies, 51 articles were reviewed. Management paradigms throughout the articles include (1) removal of infection, (2) ensuring patency of sinus outflow tracts, (3) tensionless multilayered closure using well vascularized tissue, and (4) prevention or minimization of future risk factors for fistula formation.

This article informs surgeons on reconstructive options for sinocutaneous fistulae including a novel description of the buccal fat flap.

To review the experience of 3 hospitals with airway management during surgery for substernal goiter and identify preoperative factors that predict the need for advanced airway management techniques.

A retrospective chart review between 2009 and 2017 of patients with substernal goiter treated surgically at 1 of 3 hospitals was performed.

Of the 179 patients included in the study, 114 (63.7%) were female, the mean age was 55.1 years (range 20-87). Direct laryngoscopy or videolaryngoscopy was successful in 162 patients (90.5%), with fiberoptic intubation used for the remaining 17 patients. Thirty-one patients (17.4%) required >1 intubation attempt; these patients had larger thyroids (201.3 g, 95% CI 155.3-247.2 g) than those intubated with 1 attempt (144.7 g, 95% CI 127.4-161.9 g,

 = .009). Those who required >1 attempt had higher BMI (38.3, 95% CI 34.0-42.6 vs. 32.9, 95% CI 31.5-34.3,

 = .02). Mallampati score was found to be a predictor of >1 attempt, though tracheal compression and tracheal shift were not found to be predictors of >1 attempt, nor was the lowest thyroid extent. BMI was the only independent factor on multivariable logistic regression of needing >1 attempt (odds ratio 1.056, 95% CI 1.011-1.103,

 

 .015).

The majority of patients undergoing surgery for substernal goiter can be intubated routinely without the need for fiberoptic intubation. Thyroid-specific factors such as lowest thyroid extent and mass effect of the gland on the trachea do not appear to be associated with difficult intubation, whereas classic patient factors associated with difficulty intubation are.

Children at end of life have unique and complex care needs. Although there is increasing evidence about pediatric concurrent hospice care, the health care services received while in hospice have not received sufficient attention.

To examine the health care services, unique clusters of health care services, and characteristics of the children in the clusters.

Multiple data sources were used including national Medicaid claims data. Children under 21years in pediatric concurrent hospice care were included. Using Medicaid categories assigned to claims, health care services were distributed across 20 categories. Latent class analysis was used to identify clusters of health care services. Demographic profiles of the clusters were created.

The 6,243 children in the study generated approximately 500,0000 non-hospice, health care service claims while enrolled in hospice care. We identified 3 unique classes of health care services use low (61.1%), moderate (18.1%), and high (20.8%) intensity. The children in the 3 classes exhibited unique demographic profiles.
