The Scottish Borders general practitioners exercise referral scheme (GPERS).

OBJECTIVE: This article describes the Scottish Borders General Practitioners Exercise Referral Scheme (GPERS). Results from a survey carried out three to five years after participants were first referred to the scheme are described. DESIGN: A semi-structured postal questionnaire was sent out with a pre-paid reply envelope. SETTING: Participants who had been referred to GPERS centres in Peebles and Hawick between 1994-1996 inclusive. SUBJECTS: Three hundred and twenty four participants who were referred to GPERS who were known to be still alive or living in the area. RESULTS: Forty percent of questionnaires were returned. Over 40% of these respondents were still significantly active at least twice a week. Almost two-thirds of respondents were either a lot or a little more active than when they were first referred. GPERS had helped respondents make other changes to their lives, and almost 90% were either satisfied or very satisfied with GPERS. CONCLUSION: The features which make GPERS different from most exercise referral schemes are likely to have contributed to its success. GPERS does enable many participants to become more active, independently, for at least three to five years after referral, which will have significant health improvement consequences.

Protection conferred by a fully recombinant sub-unit vaccine against Yersinia pestis in male and female mice of four inbred strains.

In this paper, we describe for the first time the use of a fully recombinant sub-unit vaccine for plague. We have compared the protection afforded by the recombinant vaccine against Yersinia pestis in male and female mice of four inbred strains. We also determined the in vivo cellular memory and antibody response after one year. The recombinant vaccine was capable of inducing protective immunity, against subcutaneous and aerosol challenge, in mice from all four strains. Although, there was some breakthrough in the CBA males challenged with 10(7) median lethal dose (MLDs) the other mice regardless of sex or strain were well protected even at this extreme challenge dose. In both male and female mice, the specific IgG titres to both antigens peaked at day 28 and 35 and in female mice these titres were maintained for >1 year.

Iontophoretic vincristine in the treatment of postherpetic neuralgia: a double-blind, randomized, controlled trial.

The effect of iontophoretic administration of vincristine in the treatment of postherpetic neuralgia (PHN) was investigated in a prospective, double-blind, placebo-controlled trial. Twenty patients with intercostal or lumbar PHN for more than 6 months that was unresponsive to conventional medical therapy were randomized to receive vincristine 0.01% (n = 11) or saline (n = 9), by iontophoresis over 1 hour daily for 20 days. Demographics and median duration of pain were similar in both groups. Pain scores decreased over the treatment period and were significantly lower on day 20 compared to baseline in both groups. Pain relief was described as moderate or greater in 40% of patients with vincristine and 55% of patients with placebo. There was no statistical difference an actual pain scores on day 20 between the two groups. Moderate or greater pain relief was maintained in 30% of patients with vincristine and 33% of patients with placebo at follow-up on day 90. We conclude that iontophoresed vincristine is no better than iontophoresed saline in the treatment of PHN. The maintained improvement in both groups at 3 months follow-up may reflect the natural history of PHN, or might possibly by related to a beneficial effect of iontophoresis.

The separation of alginate biosynthesis and acetylation in Pseudomonas syringae.

Seaweed alginate was acetylated by resting cells of Pseudomonas syringae subsp. phaseolicola ATCC 19304. Physiological studies on this strain and its UV-induced mutants showed no correlation between bacterial alginate biosynthesis and acetylation. Specific yields of alginate and degree of acetylation in these polymers varied with strain and culture medium. This was indirect evidence that alginate biosynthesis is separate from polysaccharide acetylation. It indicated that the enzyme system involved in alginate biosynthesis was not directly linked to alginate acetylation and explained why microbial acetylation of seaweed alginates was possible.

The impact of a guideline-driven computer charting system on the emergency care of patients with acute low back pain.

Federal guidelines for the treatment of acute low back pain were locally modified and made more specific. These guidelines were then programmed into a rule-based computer charting system which provides real-time advice regarding documentation, testing, treatment, and disposition of emergency department patients with this condition. In a time-series off-on experiment the system was shown to significantly improve documentation of the medical record and discharge instructions. There was little effect on the appropriateness of testing and treatment and the cost of care. These findings contrast with our previous experiment using a similar program for the care of health care workers exposed to body fluids. In that study both the appropriateness of care and the cost-effectiveness of care were substantially improved.

Granular and extra-granular forms of immunoreactive calcitonin in normal rat "C" cells.

The intracellular localization of the intermediate calcitonin-related peptides produced during calcitonin maturation (CT, 3.4 Kd) from the polyprotein precursor (15 Kd) has been studied by means of subcellular fractionation of normal adult rat thyroid using a continuous hypertonic Percoll gradient. A fraction B (Bottom), containing the secretory granules, was separated from a fraction T (Top) constituted of rough and smooth membranes devoid of granules. Immunoreactive calcitonin extracted from both fractions was heterogeneous when analysed by gel electrophoresis followed by radioimmunoassay. In fraction T, the immunoreactive molecules assayed were associated with the membranes. Their apparent molecular weights (lower than 18 Kd) were compatible with the intermediates predicted by the aminoacid sequence of the precursor. However the maturation was not complete, as indicated by the absence of the monomer. The smallest molecular weight detected (4-4.5 Kd) was compatible with a calcitonin-katacalcin uncleaved molecule. These data strongly suggest the occurrence of a cleavage separating the N-terminal part of the molecule during the pre-granular step of calcitonin secretory pathway. In the granular fraction, the monomer constituted the granular matrix, representing 65% of the total immunoreactivity. The remainder was associated with the granules membranes, consisting of the 4-4.5 Kd precursor and some 43 Kd material which has already been demonstrated by others to be covalent polymers of calcitonin [17]. It is thus concluded that a second cleavage could take place in the granules where the major immunoreactive form is the processed calcitonin, either as free monomer or as covalent polymers associated with the membrane of the granules.

Elucidation of the nucleotide sequence of chicken calcitonin mRNA: direct evidence for the expression of a lower vertebrate calcitonin-like gene in man and rat.

Calcitonin shows considerable divergence in amino acid sequence between lower vertebrates and higher vertebrates. Immunoreactive salmon-like calcitonin molecules are present in the thyroid of man and rat. Elucidation of the almost complete sequence of chicken calcitonin mRNA revealed that the calcitonin precursor in chickens had the same organisation as in higher vertebrates (man and rat) but showed considerable differences in amino acid sequence. cDNA probes specific for chicken calcitonin mRNA hybridized to poly(A)-rich RNA extracted from a case of medullary carcinoma of the thyroid and from murine thyroid. These results suggest the expression in man and rat of a gene coding for an avian calcitonin-like precursor.

Patient attitudes to perioperative suppository administration for postoperative analgesia.

Four hundred surgical patients were questioned preoperatively to ascertain their attitudes to suppository analgesia. Given a choice, 82 per cent of patients expressed a preference for intramuscular administration of diclofenac, with 18 per cent choosing a suppository. Males were more likely than females to choose an intramuscular injection. Males choosing a suppository were more likely to belong to a higher socio-economic group while females choosing a suppository were more likely to be married. Twenty-three per cent of patients who initially opted for intramuscular administration changed to suppository administration when the possibility of pain or discomfort at the injection site was explained. Females who changed to suppository administration were more likely to belong to a higher socio-economic group and to be married. Twenty-seven per cent of patients choosing an intramuscular injection expressed concern if a suppository were to be inserted without consent. Eleven per cent of patients choosing a suppository expressed similar concern. There is an overall reluctance, particularly within the male population to accept suppository analgesia. Patients from higher socio-economic groups may be more willing to accept what they perceive to be less traditional forms of treatment.
