A 55-year-old man who has had ankylosing spondylitis for over 20 years developed gradually increasing pain and sensory disorders in the legs, as well as mild foot and toe elevator weakness. There was ...no evidence of inflammatory activity. Clinical, neurophysiological and neuroradiological examination revealed a cauda equina syndrome as a late complication of ankylosing spondylitis. There is no known causal treatment.
Stressors and stress management behaviors reported by 52 myocardial infarction (MI) patients were identified from a content analysis of transcriptions of nurse/patient/spouse interactions that took ...place 30 days postinfarction. Subjects defined stress primarily in terms of distress related to appraisals of harm, loss, or threat. Stressors and stress management behaviors varied, although subjects were similar in age and occupation and were in the same phase of recovery. Most stressors related to recent myocardial infarction and pertained to thoughts and feelings more than to external events. Others, related to family and/or work, were ongoing before the MI. Stress management behaviors comprised a continuum of physical, cognitive, and verbal behaviors ranging from active to passive. Avoidance of situations, ignoring situations, expressing feelings, and thinking things through were the four major modes of stress management behaviors. Implications for rehabilitation nursing practice are identified.
An experimental group was given an intervention program which included a discussion of assessment data, identification of problems, and establishment of goals. No differences were found between ...experimental and control groups for either medical regimen adherence or societal adjustment. Attitudes and perceived beliefs of others were predictive of adherence. (Abstract amended)
This study investigated relationships between demographic and medical variables, attitudes, perceived beliefs of others, and intentions toward medical regimen adherence and actual posthospitalization ...regimen adherence. During hospitalization, attitudes, perceived beliefs of others, and intentions toward prescribed medical regimen were elicited from 112 persons recovering from a first time myocardial infarction (MI). Six to 9 months posthospitalization, attitudes, perceived beliefs of others, and adherence behaviors were assessed. Multiple regression analysis indicated that, during hospitalization, attitudes and perceived beliefs of others were strong indicators of intentions to adhere to the medical regimen, but they were not indicators of actual adherence posthospitalization. Posthospitalization, attitudes and perceived beliefs of others were strong indicators of actual regimen adherence. Findings indicate rehabilitation plans for the MI patient should be individualized for hospital and home and should include data on health belief variables.

In this letter, an additively manufactured 3dB hybrid coupler is presented. While the geometrical structure is generated by a stereolithography (SLA) printer from UV curable photopolymer resin as one ...single part, conductive coating is provided by an electroless silverplating process. The utilized slotted waveguide approach improves the solvent flow during metal plating and therefore enables the fabrication of complex waveguide structures. Measured imbalance between the through and coupling ports stays below 1.5 dB over the entire E-band, while the respective phase difference ranges only between 87° and 91° despite the challenges of additive manufacturing in such frequency regions.
A barium sulphate-gelatine mixture was injected into the veins in the left lobe of 50 human livers which were then x-rayed. The radiographs were compared with the pathological and anatomical findings ...and enlargements were studied and compared with the histology. A correlation was found between the venogram and the macroscopic and microscopic changes, particularly in various forms of cirrhosis of the liver. The scope and limitations of hepatic venography were studied with respect to solitary and diffuse liver metastase.
