To compare the severity of inpatient hospitalizations between undocumented immigrants and Medi-Cal patients in a large safety-net hospital in Los Angeles, California. We conducted a retrospective analysis of all 2019 inpatient stays at a Los Angeles hospital (n = 22 480), including patients of all races/ethnicities. We examined 3 measures by using insurance status to approximate immigration status: illness severity, length of hospital stay, and repeat hospitalizations.

The use of continuous insulin pump systems for effective management of glycemic control in the patient with type 1 diabetes mellitus (T1DM) is steadily increasing. Although the types of devices and their respective manufacturers vary, insulin pumps all utilize similar underlying concepts based on the delivery of exogenous insulin to patients with T1DM in manners that more closely approximate the normal biologic function and performance of the pancreas. As insulin pumps becomes more commonplace and their use more widespread, the sedation or anesthesia provider must ensure familiarity with the basic knowledge of pump function and the various perioperative management considerations.

This study provides trends in the discipline of dental anesthesiology. A questionnaire-based survey was sent to 338 members of the American Society of Dentist Anesthesiologists to evaluate practice patterns. One focus of the study was modality of sedation/anesthesia used for dentistry in North America.

The incidence of anaphylactic/anaphylactoid reactions has been reported to vary between 1 : 3500 and 1 : 20,000 cases with a mortality rate ranging from 3 to 9%. Clinical signs present as skin rash, urticaria, angioedema, bronchospasm, tachycardia, bradycardia, and hypotension. Rapid identification and treatment are crucial to overall patient prognosis, as delayed intervention is associated with increased mortality.

Genomic rearrangements of chromosome 15q11-q13 cause diverse phenotypes including autism, Prader-Willi syndrome (PWS), and Angelman syndrome (AS). This region is subject to genomic imprinting and characterized by complex combinations of low copy repeat elements. Prader-Willi and Angelman syndrome are caused primarily by 15q11-13 deletions of paternal and maternal origin, respectively.

Stem cells resident in adult tissues are principally quiescent, yet harbor enormous capacity for proliferation to achieve self renewal and to replenish their tissue constituents. Although a single hematopoietic stem cell (HSC) can generate sufficient primitive progeny to repopulate many recipients, little is known about the molecular mechanisms that maintain their potency or regulate their self renewal. Here we have examined the gene expression changes that occur over a time course when HSCs are induced to proliferate and return to quiescence in vivo.
