We construct embedded closed minimal surfaces in the round three-sphere S(1), resembling two parallel copies of the Clifford torus, joined by m small catenoidal bridges symmetrically arranged along a square lattice of points on the torus.

Identifying the precise locus of general cognitive ability (g) in the flow of information between perception and action is an important goal of differential psychology. To localize the negative correlation between g and reaction time to a specific processing stage, we administered a speeded number-comparison task to two groups differing in average g. The participants had to respond to two stimu...

UNLABELLED The purpose of this study was to determine if there were any differences in hospitalization rates due to total psychoactive drug "load" between those using and not or formerly using psychotropic and psychoactive medications in a skilled nursing facility; to determine if the diagnosis of dementia and the change in use and load of psychotropic and psychoactive drugs influenced hospital...

hospitalization and medical experiences can be confusing and stressful for children, teens and their families. it is very common for young people and their families to have many questions when they are scheduled for surgery or hospitalization. when children are given opportunities to cope successfully with medical experiences, they may see themselves as more capable, more in control, and more r...

abstract   background: chronic obstructive pulmonary disease (copd) is a major cause of morbidity and mortality, and is an important health economic problem. since 1960, there has been an increase in mortality associated with copd, especially in men. acute exacerbations form a major component of the socioeconomic burden of copd which mainly results in long-term hospitalization. despite the high...

Objective of the study was to estimate the case-fatality of a severe exacerbation from longterm survival data presented in the literature. A literature search identified studies reporting at least 1.5 year survival after a severe COPD exacerbation resulting in hospitalization. Each study’s survival curve was divided into a critical and a stable period. Mortality during the stable period was the...

OBJECTIVES Psychiatric hospitalization though burdensome remains a very important therapeutic option for severely-ill psychiatric patients. Hospitalization in general hospital psychiatry units (GHPU) are often regarded as the best option. A study was carried out with the purpose of assessing socioeconomic and medical variables associated with success and failure of hospitalization. METHODS A ...

STUDY OBJECTIVE To evaluate the effects of a new respiratory management protocol on respiratory morbidity and hospitalization rates for patients with Duchenne muscular dystrophy (DMD). DESIGN A retrospective cohort study. METHODS Using a protocol in which oxyhemoglobin desaturation was prevented or reversed by the use of noninvasive intermittent positive pressure ventilation (IPPV) and assi...

BACKGROUND AND OBJECTIVES Conversion from central venous catheters to a graft or a fistula is associated with lower mortality risk in long-term hemodialysis (HD) patients; however, a similar association with hospitalization risk remains to be elucidated. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We conducted a prospective observational study all maintenance in-center HD patients who were ...

The decline in blood pressure (BP) in essential hypertensives following hospitalization may result from: 1) regression toward the mean; 2) reduction of anxiety as patients habituate to a new environment; 3) the placebo effect of medication; and 4) an independent effect of hospitalization itself. A randomized crossover study of 12 essential hypertensives demonstrated a fall in supine blood press...
