Back symptoms and psychological perception of work. A study among nursing aides in a geriatric hospital.

233 nursing aides in a geriatric hospital were interviewed about back symptoms and asked to fill in a questionnaire about their psychological perception of their work. Seven psychological scales and a variable of the overall satisfaction with the job were tested against the presence/absence of cervical, thoracic and low-back symptoms. Nursing aides with thoracic and low-back symptoms exhibited in general a lower level of overall satisfaction with the job, perceived more negative relations with supervisors and workmates and perceived greater strain and a greater demand for physical and psychic strength. The psychological perception of the work was, however, only partly related to the presence/absence of back symptoms.

Long term study of hypnotic medication in geriatric patients. A study of dixyrazine, nitrazepam and amylobarbitone.

The hypnotic effect of dixyrazine (a phenothiazine derivate), nitrazepam and amylobarbitone was studied during six months in 52 geriatric inpatients (17, 16 and 19 in each group, respectively) with a mean age of 78 years. The variables registered were the percentage of patients asleep at 10 pm and 6 am and the observed number of awakenings. Certain mental and somatic variables were rated according to a schedule for geriatric behaviour. The observations were made every two to three weeks. No systematic significant change with time was observed for any of the three drugs for the percentage of patients asleep at 10 pm or 6 am or for the number of awakenings. Nor was any difference found between the three drugs in respect of these variables. There was no significant change in somatic or mental variables according to the geriatric rating schedule. The results indicate that dixyrazine, nitrazepam and amylobarbitone retain their hypnotic effect in geriatric patients during continuous use for a six-month period. No side effects were observed that influenced the patient' behaviour. The results do not support the view that barbiturates, i.e. amylobarbitone are inappropriate as hypnotics in the elderly patient.

The role of hemiacidrin in the management of renal stones in spinal cord injury patients.

Hemiacidrin is known solvent of renal calculi. Our report concerns its use in 5 cases as the sole medical agent for dissolving pelvic stones and in 6 others to supplement an operation and dissolve postoperative residual concretions. No serious complications were noted in either group. An accurate and safe technique for its use is described. The results of the method are presented.

Kinetics of the rapid action of interferon.

The present study was undertaken to examine some factors which lead to early-appearing resistance in human cells treated with interferon. It was previously shown that two conditions required for rapid development of resistance were continuous maintenance of cultures at 37 degrees and use of more than 10 units/ml of interferon. The decay kinetics of the established resistance appear to be approximately the same whether the resistance was induced under conditions favoring rapid or slow development. With the use of actinomycin D it was shown that the mRNA for the antiviral protein is produced between 30 and 45 min after the first contact with interferon. Ruled out were the possibilities that a priming action of interferon and a newly synthesized intermediary protein were necessary for rapid development of resistance.

Renal trauma and hypertension: the role of renin.

Three patients developed hypertension following renal trauma. Trauma produced perinephric hematoma in two and renal artery thrombosis in one. Renal vein plasma renin activity (PRA) from the traumatized kidney was three to eight times greater than renal vein PRA from the untraumatized (contralateral) kidney. Peripheral PRA was elevated in all. A surgical operation lowered peripheral PRA to normal in all, but corrected hypertension in only two of three. Preoperative medical treatment with renin-suppressing pharmacologic agents correctly predicted this response to surgery. Postoperative renal vein PRA in the remaining hypertensive patient demonstrated that surgery successfully alleviated the abnormality in renin secretion. These studies suggest that excessive renin secretion initiate but other unidentified factors may contribute to the hypertension observed after renal trauma.

Psychological perception of nursing aides' work. An attitude study in a geriatric hospital.

To evaluate the psychological perception of nursing aides' work a questionnaire study was performed in a long-term care (geriatric) hospital. 233 out of 273 nursing aides participated (85.4%). Seven scales were obtained: relation with supervisors and workmates, perceived need for information, satisfaction with the work itself, perceived need for education, perceived demand for physical and psychic strength, perceived strain, adjustment to geriatric work. Differences were found between young and older nursing aides, e.g. the young nursing aides percerived less demand for physical and psychic strength and the older nursing aides had a better adjustment to geriatric work. The most important factors for the overall satisfaction with the work were satisfaction with the work itself, perceived strain, and adjustment to geriatric work. Comparisons were also made between the nursing aides and industrial workers and employees.

The relationship between some psychological factors and the outcome of medical rehabilitation.

The purpose of the present study was to investigate the relationship between some psychological factors and the outcome or rehabilitation. The subjects were 70 patients at the Department of Rehabilitation Medicine, Central Hospital, Jönköping. The mean age was 45.8 years (range 20-66). They were subjected to an intelligence test, a personality inventory and a perceptual test. The outcome of the rehabilitation was measured with ratings by the staff members and by the patient himself. Positive factors for a sucessful rehabilitation was low age, good education, good intelligence and a high degree of dominance (i.e. self-confidence, ego-strength, a need to attract attention and no guilt feelings). A negative personality factor was passive dependence (i.e. lack of independence, application for assistance and dependence on other people). The most pronounced factor was field dependence-independence. The field independent subjects reached a more sucessful rehabilitation than the field dependent. This may be due to the fact that a field independent person makes his perceptual judgements according to inner frames of reference and directs and organizes his experiences more than does the field dependent. He also uses more complex and more specialized defences and experiences his own body in an analytical fashion which results in an articulated body concept and a well-developed sense of separate identity.

Chloroplast grana membrane carboxyl groups: their involvement in membrane association.

Chloroplast membrane carboxyl groups were modified by carbodiimide activation followed by glycine methyl ester substitution, leaving the derivatized group uncharged. This charge alteration induced a number of effects similar to addition of salts to control chloroplasts suspended in a low salt medium. These include: (a) restacking or multiple membrane association in low salt-treated chloroplasts that lack grana stacks, (b) protection against polycation inhibition of photosystem I electron transfer, (c) reduction of the amount of polycations bound to the membranes, and (d) increased 90 degrees light scattering due to membrane conformational changes. Carboxyl modification also altered acid-induced conformational changes.These effects are interpretated as the results of the reduction in the surface negative charge contributed by carboxyl groups. Membrane structure at both a local, polyelectrolyte level and at the level of membrane-membrane interaction (stacking) is controlled in part by these negative, charged groups.
