Dynamic Considerations in Psychiatric Crisis Intervention

One of the most challenging tasks for psychiatrists and psychiatric residents is emergency room triage. This task becomes more frequent as more patients depend on the emergency room for psychiatric treatment. Various social and economic pressures account for an increased utilization of psychiatric triage. The government funds that were to provide community care for the ex-patients of state hospitals have never materialized in adequate amounts (1). Many of these patients become dependent transients who in a crisis must use the emergency room as a psychiatric clinic. To keep premiums down, some insurance companies have eliminated their outpatient psychiatric coverage, often limiting their clients to inpatient treatment only. As a result under-insured individuals appear in the emergency room seeking hospitalization instead of more appropriate outpatient care

Lateral Migration of a Ferrofluid Droplet in a Plane Poiseuille Flow under Uniform Magnetic Fields

The lateral migration of a two-dimensional (2D) viscous ferrofluid droplet in a plane Poiseuille flow under a uniform magnetic field is studied numerically by using the level set method. Focusing on low droplet Reynolds number flows (Red ≤ 0.05), several numerical simulations are carried out to analyze the effects of magnetic field direction and strength, droplet size, and viscosity ratio on the lateral migration behavior of the droplet. The results indicate that the magnetic field direction plays a pivotal role in the trajectory of lateral migration of the droplet and the final equilibrium position in the channel. When the magnetic field is parallel to the channel, i.e., α = 0⁰ (the direction of magnetic field), the droplet is found to settle closer to the wall with an increase in magnetic Bond number Bom, while at α = 45⁰, the droplet settles closer to the channel center. Varying the initial droplet sizes at a fixed magnetic Bond number Bom and viscosity ratio λ results in different final equilibrium positions within the channel. Additionally, the effect of different viscosity ratios on the migration behavior of the droplet is examined at variable magnetic Bond numbers Bom. At α = 45⁰, a critical steady state of deformation is found for λ = 0.5 and 1 where the droplet changes its migration direction and shifts toward the center of the channel, while at λ = 0.05, the droplet crosses the center. At α = 90⁰, the droplet is found to settle exactly at the center of the flow domain irrespective of different magnetic Bond numbers, droplet sizes, and viscosity ratios

MCI: CPAP Treatment of OSA

Introduction: An estimated 30 percent of adults (20% of men and 10% of women) in the US have sleep apnea. Approximately 60% of patients with Mild Cognitive Impairment (MCI) are also diagnosed with Obstructive Sleep Apnea (OSA). The suggested mechanism of this is damage to the brain due to hypoxia during sleep. Few studies have investigated the effect of Continuous Positive Airway Pressure (CPAP) treatment for OSA, on mild cognitive impairment. Methods: Patients are screened for eligibility based on specific inclusion and exclusion criteria. Potentially eligible patients who screen positive for MCI using the Telephone Interview for Cognitive Status (TICS) survey are enrolled. CPAP adherent (n=200), CPAP non-adherent (n=160), and no apnea control (n=100) groups are followed for 1 year total with study visits at zero and six months that include cognitive testing and brain MRI. Results: At Jefferson, 272 charts have been reviewed, with 2 patients enrolled in the study. Across all study sites, approximately 5000 charts have been reviewed, and 157 patients enrolled. We hypothesize that adherence with CPAP treatment of OSA will delay the progression of cognitive impairment. Discussion: MCI is a precursor to Alzheimers, for which there is currently no effective treatment. If CPAP proves to be effective in delaying the progression of cognitive impairment in patients with OSA and MCI, CPAP may have a clinically significant impact on patient morbidity, mortality, and quality of life
