OBJECTIVES We compared the expelled air dispersion distances during coughing from a human patient simulator (HPS) lying at 45° with and without wearing a surgical mask or N95 mask in a negative pressure isolation room. METHODS Airflow was marked with intrapulmonary smoke. Coughing bouts were generated by short bursts of oxygen flow at 650, 320, and 220L/min to simulate normal, mild and poor c...

conclusions: the patients' waiting times and the number of patients waiting to receive services in both shifts could be reduced by using multitasking persons and reallocating them to the time-consuming stage of filling prescriptions, using queuing theory and simulation techniques. background: hospital pharmacy is responsible for controlling and monitoring the medication use process and ensures ...

In the high-power settings of engine, such as maximum take-off, more power should be extracted from high-pressure spool (HPS) than low-pressure (LPS) to avoid overspeed and potential instability HPS. However, revealed in this paper, extracting HPS will degrade onboard HVDC grid stability for conventional single dc bus generation center. To address conflict, an advanced center (APGC) incorporati...

BACKGROUND/PURPOSE Two strategies are commonly used for the initial diagnosis of hypertrophic pyloric stenosis (HPS): (1) physical examination and (2) radiologic evaluation using upper gastrointestinal series (UGI) or sonography. The authors wished to determine the sensitivity and relative cost of each strategy. METHODS The charts of 234 patients presenting over 3 years with a history suggest...

Catechol-O-methyltransferase (COMT) is an enzyme that plays a key role in the modulation of catechol-dependent functions such as cognition, cardiovascular function, and pain processing. Three common haplotypes of the human COMT gene, divergent in two synonymous and one nonsynonymous (val(158)met) position, designated as low (LPS), average (APS), and high pain sensitive (HPS), are associated wit...

PURPOSE To characterize retinal morphology and visual system function in the zebrafish mutant fade out (fad) and to establish the mutant as a lower vertebrate model for Hermansky-Pudlak syndrome (HPS). METHODS Retinal morphology of fad larvae was examined between 3 and 9 days postfertilization (dpf) by standard histology, transmission electron microscopy, and immunohistochemistry examination....

Background. Hemophagocytic syndrome (HPS) is characterized by a hyperinflammatory reaction followed by alteration in cytotoxic function of Th1 lymphocytes and natural killer cells. We report a rare case of a patient that presented with fever and pancytopenia due to HPS associated with Hodgkin's lymphoma (HL). Case Report. A 69-year-old Caucasian woman was admitted presenting with complaints of ...

There have been a small number of cases of scrub typhus-associated hemophagocytic syndrome (HPS), most of which were treated successfully using adequate antibiotics. Here, we report a case of Epstein-Barr virus (EBV)-associated HPS after scrub typhus infection that was not improved using antirickettsial treatment. A 73-year-old male who had been diagnosed with scrub typhus according to an escha...

Hantavirus pulmonary syndrome (HPS), a severe respiratory disease with high mortality caused by rodent-borne hantaviruses, has previously been identified in the United States and Canada as well as central and southern South America. In late 1999 and early 2000, an outbreak of acute illness compatible with HPS was reported in Los Santos, Panama, with the death of 3 of the 12 (25%) suspected case...
