Exploring the views of nurse prescribing among Macmillan nurses

Nurse prescribing is a key government initiative which aims to enhance patient care. The aim of this study was to investigate the prescribing practice of specialist nurses working in cancer and palliative care and to explore the benefits of and barriers to uptake of nurse prescribing training. A national postal survey of 2252 Macmillan nurses was undertaken using a structured questionnaire with open-ended questions. Data were analyzed using thematic content analysis for 1575 respondents (70% response rate). Only 13% (203) had undergone prescribing training and of these 105 provided responses to the open questions concerning training and of the 87% (1372) who had not undergone the training, 423 provided details on barriers to nurse prescribing training. The data presented in this paper draw from this data. The findings indicate that those who prescribed gave the prospect of improving care as the main reason for undertaking nurse prescribing training. The main reasons why these specialist nurses did not undertake training were: resource issues particularly with respect to backfill while training, lack of medical support and mentorship, concerns about the relevance of prescribing as a nursing role and prioritizing other courses. If nurse prescribing is to be more widely available for cancer and palliative care patients it is important in both primary and secondary care to address the resource and support issues.     

Laparoscopic Treatment of Boerhaave’s Syndrome: a Case Report and Review of the Literature

Spontaneous rupture of the oesophagus (Boerhaave’s syndrome) is a rare life-threatening disease requiring urgent surgical management. Symptoms can masquerade many other clinical disorders like acute myocardial infarction, dissecting aneurysm or upper gastro-intestinal tract diseases. Without prompt diagnosis and treatment, Boerhaave’s syndrome has a very high mortality rate.

We report a case of perforation of the distal oesophagus. A 40-year-old male patient presented at the emergency department with a classic history of acute epigastric pain and dyspnoea after an episode of vomiting. On clinical examination we found a firm, tender abdomen and cervical subcutaneous emphysema. Boerhaave’s syndrome was suspected on a clinical basis and was confirmed by thoraco-abdominal CT scan, showing an apparent pneumomediastinum and fluid at both lung bases. The patient underwent surgical repair of the distal oesophageal tear by laparoscopy. A mediastinal drain was left behind and a feeding gastrostomy was established. After initial improvement, the patient developed fever and dyspnoea. A thoracic CT scan revealed left-sided empyema. A thoracoscopic drainage of pus was performed and antibacterial and antifungal treatment was adapted. The patient recovered well and was discharged from the hospital 34 days after admission.     

Titration of an SIVmac251 stock by vaginal inoculation of Indian and Chinese origin rhesus macaques: transmission efficiency, viral loads, and antibody responses.

The purpose of this study was to determine whether rhesus monkeys of Chinese origin are suitable for studies of mucosal lentivirus transmission by comparing the relative ability of these animals and rhesus macaques of Indian origin to become infected by vaginal (IVAG) inoculation with SIVmac251. In addition, we sought to test the hypothesis that differences in viral load during the first few weeks after inoculation were due to the relative strength of the anti-SIV immune responses in the two populations of rhesus macaques. Significant difference was not observed between the number of Indian and Chinese origin monkeys that were infected after IVAG SIV inoculation in this study. For 8-9 weeks after infection there was considerable overlap in the range of viral loads among the Indian and Chinese animals and the variation among the Indian origin animals was greater than the variation among the Chinese origin monkeys. By 6 weeks postinfection, viral loads in SIV-infected Chinese origin monkeys tended to be at the lower end of the range of viral loads observed in SIV-infected Indian origin monkeys. The strength of the anti-SIV antibody response was also more variable in the Indian origin rhesus macaques, but at 6-8 weeks postinfection, Chinese and Indian origin rhesus macaques had similar titers of anti-SIV antibodies. Microsatellite allele frequencies differed between Chinese and Indian rhesus macaques; however, the majority of alleles present in Indian-origin animals were also found in Chinese macaques. Together these results show that host factors, other than geographic origin, determine the ability of a rhesus macaque to be infected after IVAG SIV exposure and that geographic origin does not predict the viral load of SIV-infected animals during the first 8-9 weeks after IVAG inoculation.     

Effect of vaginally administered (Ala)-magainin II amide on the morphology of implantation stage endometrium in the rhesus monkey (Macaca mulatta)

Intravaginal administration of an anti-microbial agent, (Ala^8,13,18)-magainin II amide, during blastocyst implantation inhibits pregnancy establishment in a dose-related manner in the rhesus monkey (Macaca mulatta). In the present study, mated female rhesus monkeys were vaginally inserted with tampons containing vehicle (Group 1; N = 5) and test agent (magainin, 0.5 mg/animal; Group 2; N = 6) on cycle day 20. Endometrial tissue samples were collected on Cycle Day 24 from all monkeys and processed for morphometric and ultrastructural analysis. Concentrations of estradiol-17β, progesterone, and chorionic gonadotrophin in peripheral circulation were determined, which revealed that two monkeys in Group 1 were pregnant while no animals were pregnant in Group 2. Endometrial morphology, however, revealed histologic evidence of pregnancy in three out of the six magainin-treated animals. It appears that intra-vaginal administration of magainin II amide had a marginal effect on the implantation stage endometrium and the initiation of the implantation process in the rhesus monkey.     

Verletzungen des Schultergelenks

The past few years have seen profound changes in diagnostic imaging of the injured shoulder. Once the history has been taken and a clinical examination conducted, standard radiographic evaluation (in two planes) is still the basis for any further diagnostic imaging. Ultrasonography, contrast computed (arthro-) tomography, (arthro-)MR and bone scintigraphy can be used to reveal more specific details of the extent and severity of shoulder injuries, particularly the status of the cuff musculature, the glenoid labrum and the capsule. To avoid unnecessary or repeated use of such expensive examinations, the potential usefulness and the limitations of each of these methods are shown with reference to the most common injuries.     

Ultrasonic assessment of fetal growth in the nonhuman primate (Macaca mulatta)

Serial ultrasound measurements of fetal growth were made during uncomplicated pregnancy in 28 time-mated rhesus monkeys. Gestational sac (GS) size, crown-rump length (CRL), biparietal diameter (BPD), head circumference (HC), head area (HA), abdominal circumference (AC), abdominal area (AA), and femur length (FL) were measured. Average longitudinal growth curves for each parameter were obtained from individual fetal growth curves. Data analysis indicated that the linear model was optimal for GS, CRL, HA, AA, and FL. The linear-quadratic model was optimal for AC, and the linear-cubic model was optimal for BPD and HC.     

Components of biological variation, including seasonality, in blood concentrations of TSH, TT3, FT4, PRL, cortisol and testosterone in healthy volunteers

OBJECTIVEThere are few detailed studies of annual or seasonal variations in hormone concentrations in man. This study examines the components of biological variation, including seasonality, in plasma TSH, total T3 (TT3), free T4 (FT4), PRL, cortisol and testosterone in healthy volunteers. DESIGNMonthly blood samplings for the assay of the above hormones were collected during one calendar year. SUBJECTSThirteen normal men and 13 normal women participated in the present study (mean age 38.7 ± 13.4 years). MEASUREMENTSAssays of TSH, TT3 and FT4 were carried out by means of Immunoradiometric assays (IRMA), PRL by ELISA, cortisol by a fluorescence immunoassay, and testosterone with RIA. The time series were analysed by means of (bivariate or multivariate) spectral and cosinor analyses. RESULTSSignificant annual, four-monthly and biannual rhythms were detected in serum TSH; the lowest TSH values were observed in spring. A significant annual rhythm was detected in TT3, with lower values in spring and summer than in the other seasons. The peak–trough differences in the yearly variation expressed as a percentage of the mean were 29.1% and 8.2% for TSH and TT3, respectively. The yearly variation in plasma cortisol was significantly different between men and women: in men, 5.9% of the variation was explained by an annual rhythm, while in women 14.7% was explained by the fourth and seventh harmonical wave. The peak–trough differences in the yearly variation in plasma cortisol were 17.6% and 31.8% in men and women, respectively. There were no significant seasonal rhythms in PRL, FT4 or testosterone. The intraindividual/interindividual CV values were: TSH 29.3/48.4%, TT3 9.4/18.5%, FT4 7.1/9.1%, PRL 39.2/65.0%, cortisol 21.7/46.2%, and testosterone 12.6/40.8%. CONCLUSIONSThe degree of individuality measured in the plasma hormones is such that conventional population-based reference ranges may not correctly identify major alterations in these hormones in individual subjects.
