Existing in-between two worlds: supporting asylum seeking women living in temporary accommodation through a creative movement and art intervention

ABSTRACT

In this reflective article we introduce Moving Space, a creative movement and art project supporting female Asylum Seekers as they move through the transient space of temporary accommodation. We explore how this cross-modal approach supports women to anchor experiences of displacement, loss and trauma through the use of embodied and visual creative process. Moreover, we argue that the transient nature of the therapeutic space brings into focus women’s resourcefulness and resilience despite the adversity and uncertainty they are experiencing.     

Antibody to hepatitis B surface antigen in haemophiliacs on long-term therapy with Scottish factor VIII.

Thirty-five patients with haemophilia A were studied clinically and serologically between 1971-2 and 1975-6 for evidence of hepatitis B infection. One patient suffered from clinical hepatitis B, and a further eight patients showed antibody responses to hepatitis B surface antigen (HBsAg) consistent with exposure to HBsAg during this period. No evidence for HBsAg exposure was found in 14 patients, while the remaining 12 patients had high titres of antibody to HBsAg at both times and no inferences could be drawn about HBsAg exposure. All patients had received exclusively replacement factor VIII material prepared locally from HBsAg-screened voluntary Scottish blood donations. From the details of the therapy given we calculated that the rate of HBsAg seroconversion in these patients represented about 0.3 HBsAg-containing donations/1000 donations.     

Serotonin mediates learning-induced potentiation of excitability

Sensitization potentiates excitability in an interneuron, the S-cell, that is critical for this form of learning in the whole-body shortening reflex of the medicinal leech. Serotonin (5-HT) also increases S-cell excitability, and serotonergic modulation is known to be critical for sensitization of whole-body shortening, suggesting that 5-HT mediates learning-induced enhancement of S-cell excitability. In this paper, the role of 5-HT in mediating sensitization-induced potentiation of S-cell excitability was examined. Potentiation of S-cell excitability by 5-HT was blocked by the 5-HT receptor antagonist methysergide and by intracellular injection of the G-protein inhibitor GDP-beta-S, indicating that a metabotropic 5-HT receptor was involved. Bath application of Rp-cAMP, an inhibitor of protein kinase A (PKA), blocked 5-HT-induced potentiation of excitability, whereas db-cAMP, a cAMP analogue that activates PKA, mimicked the potentiating effects of 5-HT on the S-cell. During sensitization of the shortening reflex in semi-intact preparations, methysergide and Rp-cAMP prevented learning-induced potentiation of S-cell excitability, as well as the increase in S-cell activity that normally occurs during sensitization. Furthermore, sensitization-induced increases in the shortening reflex did not occur in preparations treated with methysergide or Rp-cAMP. These results demonstrate that sensitization-induced enhancement of S-cell excitability is mediated by 5-HT and suggests that these changes may contribute to this form of learning.     

Intracellular factors, but not virus receptor levels, influence the age-related outcome of DHBV infection of ducks.

Previous serological studies of experimental infection with duck hepatitis B virus (DHBV) have shown that the outcome of infection depends largely on the age of the duck at the time of inoculation. To examine the hypothesis that decreased susceptibility with increased age might be due to the loss of the virus receptor on hepatocyte membranes in adult ducks, we performed receptor binding studies using intact serum-derived DHBV virions and purified liver plasma membranes from both young ducklings and adult ducks. These studies showed that (1) DHBV was able to bind specifically to duck liver plasma membranes but not to internal membranes; (2) this binding could be inhibited by a monoclonal antibody to DHBV preS, a corresponding region in hepatitis B virus that binds to human hepatocytes; and (3) there was no significant difference in the receptor binding ability between plasma membranes from ducklings and from adult ducks. Since hepatocytes in the neonatal ducks are actively dividing, in contrast to the situation in adult ducks, we examined the effect of partial hepatectomy on DHBV-carrier ducks. A sharp increase was noted in the level of DHBV in the serum after partial hepatectomy suggesting that DHBV replication was enhanced in dividing hepatocytes. Thus the age-related difference in susceptibility of ducks to DHBV infection is not due to loss of the receptor but may be related to an intracellular event associated with cell division.     

Growth and maturation of cardiac myocytes in fetal sheep in the second half of gestation

Right (RVFW) and left (LVFW) ventricular free wall cardiac myocytes were collected from 25 fetal sheep aged 77-146 days gestation (term = 150 days gestation), six saline-infused catheterized fetal sheep (129 GD), and five lambs to measure gestational changes in uni- and binucleated cardiac myocyte numbers and cell volumes by confocal microscopy. At 77 days gestation, 2% of the myocytes were binucleated, which increased to 50% at 135 days gestation and 90% at 4-6 weeks after birth. RVFW uni- and binucleated myocytes were larger than those in the LVFW, and cell volumes of RVFW uni- and binucleated and LVFW binucleated myocytes (but not LVFW uninucleated myocytes) increased with gestation. Before birth, the approximate number of myocytes was greater in the LVFW than in the RVFW (P < 0.001). Before 110 GD, cardiac growth appeared to be due to myocyte hyperplasia, as approximate myocyte numbers and VFW weight increased at the same rate. After 110 days gestation, the approximate myocyte number/g VFW weight decreased, which suggests that myocyte hypertrophy, as well as hyperplasia, was occurring in association with the appearance of a greater proportion of binucleated cells after that time. By 4-6 weeks of age, there was marked hypertrophy of myocytes and an apparent reduction in myocyte number.     

Modulation of pulmonary inflammation after endotoxin inhalation with a platelet-activating factor antagonist (48740 RP)

An acute pulmonary response was induced in guinea pigs and hamsters by inhalation of bacterial endotoxin in the form of a purified lipopolysaccharide (LPS). Pretreatment with the platelet-activating factor (PAF) antagonist, 48740 RP, inhibited damage to endothelial cells, decreased vascular permeability and the number of neutrophils in the airways 24 h after exposure to LPS. The increase in the number of platelets in the airways caused by endotoxin was not affected. The results suggest that PAF modulates early inflammation after endotoxin inhalation.     

Radiation exposure of the families of outpatients treated with radioiodine (iodine-131) for hyperthyroidism.

Patients who receive radioiodine (iodine-131) treatment for hyperthyroidism (195-800 MBq) emit radiation and represent a potential hazard to other individuals. Critical groups amongst the public are fellow travellers on the patient's journey home from hospital and members of the patient's family, particularly young children. The dose which members of the public are allowed to receive as a result of a patient's treatment has been reduced in Europe following recently revised recommendations from ICRP. The annual public dose limit is 1 mSv, though adult members of the patient's family are allowed to receive higher doses, with the proviso that a limit of 5 mSv should not be exceeded over 5 years. Unless the doses received during out-patient administration of radioiodine can be demonstrated to comply with these new limits, hospitalisation of patients will be necessary. The radiation doses received by family members (35 adults and 87 children) of patients treated with radioiodine at five UK hospitals were measured using thermoluminescent dosimeters mounted in wrist bands. Families were given advice (according to current practice) from their treatment centre about limiting close contact with the patient for a period of time after treatment. Doses measured over 3-6 weeks were adjusted to give an estimate of values which might have been expected if the dosimeters had been worn indefinitely. Thirty-five passengers accompanying patients home after treatment also recorded the dose received during the journey using electronic (digital) personal dosimeters. For the "adjusted" doses to infinity, 97% of adults complied with a 5-mSv dose limit (range:0.2-5.8 mSv) and 89% of children with a 1-mSv limit (range: 0.2-7.2 mSv). However 6 of 17 children aged 3 years or less had an adjusted dose which exceeded this 1 mSv limit. The dose received by adults during travel was small in comparison with the total dose received. The median travel dose was 0.03 mSv for 1 h travel (range: 2 microSv-0.52 mSv for 1 h of travel time). These data suggest that hyperthyroid patients can continue to be treated with radioiodine on an out-patient basis, if given appropriate radiation protection advice. However, particular consideration needs to be given to children aged 3 years or younger. Admission to hospital is not warranted on radiation protection grounds.     

Computed tomography diagnosis of tracheobronchopathia osteochondroplastica

Tracheobronchopathia osteochondroplastica (TO) is a rare benign disease characterized by the presence of osseous and cartilaginous submucosal nodules projecting into the tracheobronchial tree. Most cases are asymptomatic and discovered incidentally at post‐mortem. We identified a case of TO on thoracic spiral CT and confirmed the diagnosis on bronchoscopy. This article reviews the imaging characteristics of TO, and shows the 3‐D virtual bronchoscopic and multiplanar reconstruction appearances of TO.     

Diagnosis of pulmonary embolism: Ventilation perfusion scintigraphy versus helical computed tomography pulmonary angiography

The present study compared the accuracy of ventilation perfusion scintigraphy (VQS) and CT pulmonary angiography (CTPA) for the diagnosis of pulmonary embolism. This was a prospective observational study of 112 patients with suspected pulmonary embolism (PE) who could be studied with both investigations within 24 h. Results were compared to final diagnosis at completion of 6-month follow up, using receiver operating characteristic (ROC) analysis. Pulmonary embolism was diagnosed in 27 referred patients (24%). The sensitivity and specificity of VQS and CTPA were similar to that reported from the literature. A normal VQ scan had the highest negative predictive value (100%), while a high-probability VQ scan had the highest positive predictive value (92%). There was no overall difference (area under the ROC curve (AUC)) between VQS (AUC (95% CI) = 0.82 (0.75,0.89)) and CTPA (AUC = 0.88 (0.81,0.94)) for the diagnosis of PE. Among patients with abnormal chest X-rays, CTPA (AUC 0.90 (0.83,0.97)) appeared somewhat better than VQS (AUC 0.78 (0.68,0.88)) but this difference did not reach statistical significance. In this instance, CTPA is at least as accurate as VQS and may provide an opportunity to make alternative diagnoses.
