The geriatrician employs a trained receptionist buy anafranil 10 mg free shipping, a nurse practitioner, and a social worker to help perform geriatric assessment on her patients. Which of the following statements regarding outpatient geriatric assessment for this patient is false? The patient completes a questionnaire in the waiting room to screen for common conditions in older persons B. The patient completes easily observed tasks, and his performance is assessed C. The daughter may be less likely to report increased burden of care during the ensuing year D. The cost of the assessment is covered by Medicare Key Concept/Objective: To understand methods of geriatric assessment in the outpatient setting Outpatient geriatric assessment programs may be used as an adjunct to or a substitute for routine primary care. These programs utilize self-administered questionnaires to screen for common conditions in older persons. Patients can complete these question- naires themselves or with the assistance of a trained receptionist. The questionnaire can be used to evaluate malnutrition, visual impairment, hearing loss, cognitive impair- ment, urinary incontinence, depression, physical limitations, and reduced leg mobility. The patient may be asked to perform easily observed tasks that relate to daily life, such as instrumental and basic activities of daily living. Outpatient geriatric assessment can benefit caregivers as well as patients. At present, Medicare does not cover hospital or physician geriatric assessment services. A 76-year-old woman who is recovering from a hip fracture is hospitalized at a regional hospital, where she is to undergo geriatric assessment. Which of the following statements regarding geriatric assessment units is true? Although geriatric assessment units improve quality of life, they do not affect the risk of nursing home placement B.
Accelerator/Activator Most of the bone cement formulations contain a tertiary aryl-amine discount 50 mg anafranil, N,N-dimethyl-p-toluidine (DMPT), as an accelerator for polymerization reactions. DMPT is added in the liquid part and is water soluble to a small extent. It causes the decomposition of the BPO in a reduction–oxi- dation process by electron transfer that produces a benzoyl radical and benzoate anion, as shown in Fig. It was shown that when the more reactive 4-N,N-(dimethylamino)phenethanol was used as accelerator, a higher radical concentration was observed in the polymerization system than with BPO, yielding cements with shorter setting times and increased strengths [14,15]. These two accelerators were expected to be less toxic. Compression tests revealed that compressive yield stress, strain at yield, and elastic modu- lus values were very similar to those of samples cured with DMPT and ANP, and slightly lower results were obtained with samples cured with MNP. In Boneloc , a mixture of dihydroxypropyl- p-toluidine and N,N-dimethyl-p-toluidine was used as the accelerator system. Oldfield and Ya- suda introduced 4-dimethylamino phenethyl alcohol (TDOH) as a more effective accelerator than DMPT for bone cement curing. In Bonemite , 2-5-dimethylhexane-2-5-hydroperoxide is used as the polymerization pro- moter. They used 4- dimethylaminobenzyl alcohol (DMOH) and 4-dimethylaminobenzyl methacrylate (DMMO) as the activators in the benzoyl peroxide–initiated redox polymerization for the preparation of acrylic bone cement based on polymethylmethacrylate beads of different particle sizes. They reported that the BPO/DMOH and BPO/DMMO redox systems had lower peak temperatures and longer setting times, and the cured materials presented higher average molecular weights Figure 3 Free radical formation by tri-n-butylborane (TBB). In addition, they reported that these activators were three times less toxic than the classical DMPT. When the same group used a tertiary aromatic amine derived from oleic acid, 4-N,N-dimethylaminobenzyl oleate (DMAO), as the accelerator, they obtained a 20 C decrease in the polymerization temperature and a 7-min increase in setting time.
