A 78 year old Caucasian, bed-bound, nursing home female, presented with non-tender, violaceous, indurated plaques of the skin of her anterior left thigh. Patient’s past medical history was significant for coronary artery disease, atrial fibrillation, diabetes mellitus type II, and stroke with left hemiplegia. On physical examination of her thigh, a 5X8 cm diffuse dusky red, woody hard, hematoma...

In this study, tea waste (TW) is employed for the removal of Congo red (CR) from aqueous solutions in a fixed-bed column at 30 °C. The breakthrough curves of the adsorption process of CR on TW at three different flow rates are determined. The results revealed that the breakthrough curves were dependent on flow rates in a manner in which a lower flow rate was in favor of the CR adsorption in the...

This month, we focus on current research in bed rest in pregnancy. Dr. Lorenz discusses four recent publications, and each is concluded with a "bottom line" that is the take-home message. The complete reference for each can be found in on this page, along with direct links to the abstracts.

This work studied the influence of effluent recirculation upon the kinetics of anaerobic degradation of dairy wastewater in the feedless phase of intermittent upflow anaerobic sludge bed (UASB) reactors. Several laboratory-scale tests were performed with different organic loads in closed circuit UASB reactors inoculated with adapted flocculent sludge. The data obtained were used for determinati...

I n t e r v e n t i o n Patients were allocated to bed rest (n = 84), physiotherapy (n = 83), or continuation of ADLs (n = 83). Bed rest could be done at home or in the hospital and lasted 7 days. Physiotherapy sessions were scheduled twice weekly for 4 to 8 weeks and involved segmental mobilization, disc unloading and loading exercises, and hydrotherapy. Patients in the continuation-of-ADLs gr...

For many years, average bed occupancy level has been the primary measure that has guided hospital bed capacity decisions at both policy and managerial levels. Even now, the common wisdom that there is an excess of beds nationally has been based on a federal target of 85% occupancy that was developed about 25 years ago. This paper examines data from New York state and uses queueing analysis to e...

Bed bug (Cimex lectularius L.) infestations are currently controlled by a variety of non-chemical and chemical methods. There have been few studies on the comparative effectiveness of these control techniques. We evaluated three bed bug management strategies in an apartment building: (1) non-chemical methods only (n = 9); (2) insecticides only (n = 6); and (3) integrated pest management includi...
