RESUMO
BACKGROUND: Body dissatisfaction is associated with a range of adverse outcomes, including impaired psychological health, low physical activity and disordered eating. This longitudinal study used the Factors Influencing Transitions in Girls' Active Leisure and Sport (FITGALS) dataset to examine trends in body image of adolescent females. Specifically, the study examined satisfaction with body size, physical appearance and dieting behaviour for two cohorts at transitional life phases in two geographic regions longitudinally over a 3-year period. METHODS: A sample of 732 adolescent females in Grade 7 (n = 489, 66.8 %) and Grade 11 (n = 243, 33.2 %) at randomly selected Australian metropolitan and non-metropolitan secondary schools responded to a questionnaire in three successive years from 2008 to 2010. Participants reported perceptions about their body size and physical appearance and whether they were, or ought to be, on a diet. The data were analysed using a series of longitudinal logistic regression models. RESULTS: Dieting and dissatisfaction with body size significantly increased over time and more so for older than younger girls. Region significantly moderated the effect of grade level regarding dissatisfaction with body size but not dieting. In non-metropolitan regions, those in the younger cohort were significantly more likely to be dissatisfied with their body size than the older cohort; whereas in metropolitan regions, those in the older cohort were significantly more likely to be dissatisfied with their body size than the younger cohort. Adolescent female's perceptions of their appearance were unchanged over time, region and grade level. CONCLUSIONS: Differences across time, region and grade level were found among adolescent females on body size and dieting behaviour, but not physical appearance. Adolescent females experience early and increasing body size dissatisfaction and dieting as they age, but stable perceptions of physical appearance. Age and geographic region are important considerations for the timing and targeting of interventions to address body image concerns. Further investigation of regional differences in body image perceptions and factors that affect these is warranted. The findings of this study highlight the ongoing need for strategies during adolescence to promote a healthy appreciation of body size and appearance.

BACKGROUND: The optimal treatment for respiratory syncytial virus (RSV) infection in adult immunocompromised patients is unknown. We assessed the management of RSV and other non-influenza respiratory viruses in Midwestern transplant centers. METHODS: A survey assessing strategies for RSV and other non-influenza respiratory viral infections was sent to 13 centers. RESULTS: Multiplex polymerase chain reaction assay was used for diagnosis in 11/12 centers. Eight of 12 centers used inhaled ribavirin (RBV) in some patient populations. Barriers included cost, safety, lack of evidence, and inconvenience. Six of 12 used intravenous immunoglobulin (IVIG), mostly in combination with RBV. Inhaled RBV was used more than oral, and in the post-stem cell transplant population, patients with lower respiratory tract infection (LRTI), graft-versus-host disease, and more recent transplantation were treated at higher rates. Ten centers had experience with lung transplant patients; all used either oral or inhaled RBV for LRTI, 6/10 treated upper respiratory tract infection (URTI). No center treated non-lung solid organ transplant (SOT) recipients with URTI; 7/11 would use oral or inhaled RBV in the same group with LRTI. Patients with hematologic malignancy without hematopoietic stem cell transplantation were treated with RBV at a similar frequency to non-lung SOT recipients. Three of 12 centers, in severe cases, treated parainfluenza and metapneumovirus, and 1/12 treated coronavirus. CONCLUSIONS: Treatment of RSV in immunocompromised patients varied greatly. While most centers treat LRTI, treatment of URTI was variable. No consensus was found regarding the use of oral versus inhaled RBV, or the use of IVIG. The presence of such heterogeneity demonstrates the need for further studies defining optimal treatment of RSV in immunocompromised hosts.

The applied model of mental imagery use proposed an interaction effect between imagery type and imagery ability. This study had two aims: (a) the examination of imagery ability as a moderating variable between imagery type and dispositional flow, and (b) the testing of alternative mediation models. The sample consisted of 367 athletes from Scotland and Australia, who completed the Sport Imagery Questionnaire, Sport Imagery Ability Questionnaire, and Dispositional Flow Scale-2. Hierarchical regression analysis showed direct effects of imagery use and imagery ability on flow, but no significant interaction. Mediation analysis revealed a significant indirect path, indicating a partially mediated relationship (P = 0.002) between imagery use, imagery ability, and flow. Partial mediation was confirmed when the effect of cognitive imagery use and cognitive imagery ability was tested, and a full mediation model was found between motivational imagery use, motivational imagery ability, and flow. The results are discussed in conjunction with potential future research directions on advancing theory and applications.

Risk factors for non-Aspergillus mold infection (NAMI) and the impact on transplant outcome are poorly assessed in the current era of antifungal agents. Outcomes of 124 patients receiving allogeneic hematopoietic cell transplantation (HCT) diagnosed with either mucormycosis (n=72) or fusariosis (n=52) between days 0 and 365 after HCT are described and compared with a control cohort (n=11 856). Patients with NAMI had more advanced disease (mucormycois: 25%, fusariosis: 23% and controls: 18%; P=0.004) and were more likely to have a Karnofsky performance status (KPS) <90% at HCT (mucormycosis: 42%, fusariosis: 38% and controls: 28%; P=0.048). The 1-year survival after HCT was 22% (15-29%) for cases and was significantly inferior compared with controls (65% (64-65%); P<0.001). Survival from infection was similarly dismal regardless of mucormycosis: 15% (8-25%) and fusariosis: 21% (11-33%). In multivariable analysis, NAMI was associated with a sixfold higher risk of death (P<0.0001) regardless of the site or timing of infection. Risk factors for mucormycosis include preceding acute GvHD, prior Aspergillus infection and older age. For fusariosis, increased risks including receipt of cord blood, prior CMV infection and transplant before May 2002. In conclusion, NAMI occurs infrequently, is associated with high mortality and appears with similar frequency in the current antifungal era.

Although hemorrhagic cystitis (HC) is a common complication of allogeneic hematopoietic cell transplantation (alloHCT), its risk factors and effects on survival are not well known. We evaluated HC in a large cohort (n=1321, 2003-2012) receiving alloHCT from all graft sources, including umbilical cord blood (UCB). We compared HC patients with non-HC (control) patients and examined clinical variables at HC onset and resolution. Of these 1321 patients, 219 (16.6%) developed HC at a median of 22 days after alloHCT. BK viruria was detected in 90% of 109 tested HC patients. Median duration of HC was 27 days. At the time of HC diagnosis, acute GVHD, fever, severe thrombocytopenia and steroid use were more frequent than at the time of HC resolution. In univariate analysis, male sex, age <20 years, myeloablative conditioning with cyclophosphamide and acute GVHD were associated with HC. In multivariate analysis, HC was significantly more common in males and HLA-mismatched UCB graft recipients. Severe grade HC (grade III-IV) was associated with increased treatment-related mortality but not with overall survival at 1 year. HC remains hazardous and therefore better prophylaxis, and early interventions to limit its severity are still needed.

INTRODUCTION: Diagnostic laparoscopy with appendicectomy (LA) has become the accepted method of investigation and treatment of appendicitis. However, concerns remain in cases of complicated appendicitis when many advocate conversion to an open procedure (LCOA) owing to the risk of complications. The aim of this study was to look for factors that could predict complications occurring in patients undergoing appendicectomy. METHODS: Data inclusive of all consecutive appendicectomies over a two-year period were retrieved from the computerised theatre database. Clinical details including admission inflammatory markers, complications, severity (final pathology) and length of stay were collected from the discharge letter. Readmissions were identified as those hospital identifiers had a second set of admission dates and/or a second discharge letter. RESULTS: During the 2-year study period, 517 appendicectomies were performed. Of these, 429 patients (83%) had LA and the remaining 88 (17%) had LCOA. The LA group had a mean age of 28 years (range: 2-86 years) and a mean C-reactive protein (CRP) level of 71 mg/l (range: 0-480 mg/l) while the LCOA group had a mean age of 46 years (range: 11-92 years) and a mean CRP level of 162 mg/l (range: 3-404 mg/l). These differences in age and CRP were significant (p<0.001). LA patients were less likely to have complications overall (22% vs 52%, p=0.015). Complications were independently more than twice as common with established inflammation with a CRP level of >150 mg/l (p<0.05). CONCLUSIONS: A high preoperative CRP level predicts an increased rate of postoperative complication due to established inflammation and/or infection. This raises the question of whether we should be offering primary open appendicectomies to patients with a CRP level of >150 mg/l.

BACKGROUND: The reduction in gastric cancer mortality is due to a reduction in incidence and of surgical mortality. This study was to examine adverse events in patients with gastric cancer dying under surgical care. METHODS: Adverse events in surgical care were prospectively audited in patients who died of gastric cancer in Scottish hospitals. A cohort retrospective study examining deaths and contributing adverse events was compared for the periods 1996-2000 and 2001-2005. RESULTS: Between 1996 and 2005, 1083 patients with gastric cancer died on surgical wards in Scottish hospitals. The annual number of deaths under surgical care fell significantly from an average of 128 deaths per annum in years 1996-2000 to 88 deaths per annum in 2001-2005 (p < 0.001). This occurred in parallel with the decline in gastric cancer incidence over the same period. There was an increase in the proportion of gastric cancer resections carried out in 7 major hospitals in Scotland in the second period of the study (p < 0.001). The mean number of deaths in the group of patients, who had gastric cancer resection and palliative surgery, were significantly lower in the second period of the study In addition, when all patients were considered as a group, the mean number of anaesthetic, critical care, medical management and technical surgery adverse events were significantly lower in the second study period. CONCLUSION: There has been a reduction in deaths and adverse events for patients with gastric cancer under surgical care and this has been associated with surgical subspecialisation in oesophago-gastric cancer surgery.
RESUMO
AIM: We prospectively audited adverse events for surgical patients with colorectal cancer who died under surgical care to test the hypothesis that increased critical care and consultant input could be associated with a reduction in adverse events. METHOD: Patients with a diagnosis of colorectal cancer who died under surgical care in Scotland from 1996 to 2005 underwent peer review audit using established methodologies through the Scottish Audit of Surgical Mortality. RESULTS: In the 10-year study period, 3029 patients with colorectal cancer, mean age 76 (13-105) years, died under surgical care, of whom 80% had presented as an emergency admission. Operative intervention was performed in 1557 (51%) patients of whom 1030 (34%) patients had a resection of the cancer. The annual number of patients dying after a cancer resection decreased significantly (P = 0.009). Significant decreases in adverse events were noted over time with a 67% fall in adverse events relating to critical care (P = 0.009), a 37% fall for surgical care (P = 0.04) and a significant increase in consultant anaesthetist and consultant surgeon input, but there was a 9% increase in delay as an adverse event (P = 0.006). The documented anastomotic leakage rate in patients who died increased from 8% in 1996 to 19% in 2005 (P = 0.016). CONCLUSION: The number of patients dying with colorectal cancer after surgery has decreased in recent years. Adverse events in these patients have significantly reduced over a decade with increased consultant involvement although there is the potential for further improvement.

BACKGROUND: People with type 1 diabetes may find diabetic control more difficult when working shifts. AIMS: To investigate the proportion of people with type 1 diabetes in employment undertaking shift work and diabetic control as assessed by glycosylated haemoglobin (HbA1c) among individuals undertaking shift work compared to those not doing so. METHODS: A postal questionnaire sent to all those aged 16-65 attending two city hospitals for type 1 diabetes care. HbA1c results were used to assess diabetic control. RESULTS: Twenty-two per cent (296 of 1370 eligible patients) responded. Sixty-seven (23%) respondents were involved in shift work. Shift workers had higher mean HbA1c values than non-shift workers (9.02 versus 8.35; P < 0.01). CONCLUSIONS: Poorer control of diabetes was associated with working shifts in this study. Occupational health practitioners should be aware of this association and be able to advise on management strategies to improve diabetic control while working shifts.

BACKGROUND AND AIMS: Patients with advanced gastrointestinal cancer may present late to hospital services and die under surgical care. The aim of this study was to examine end of life care in patients dying of gastrointestinal cancer in Scottish hospital surgical wards. METHODS: The Scottish Audit of Surgical Mortality prospectively peer reviews all inpatient deaths under the care of a consultant surgeon. Patients who died with gastrointestinal cancer under surgical care from 1994 to 2006 were evaluated for operative interventions, adverse events, and palliative care provision. Data was compared with inpatient data from the Information Statistics Division of NHS Scotland. RESULTS: A total of 8019 patients died with gastrointestinal cancer on a surgical ward over 12 years. For 4350 (54%), no operation or endoscopy was performed during the final admission and adverse events were identified in only 86 (2%) of these patients, most commonly due to a complication of an interventional procedures. Specialist palliative care was provided to 57% of patients and was not influenced by cancer site. CONCLUSION: A substantial proportion of patients die with gastrointestinal cancer on general surgical wards without operative or endoscopic intervention and may receive better end of life care in an acute palliative care setting.

AIM: This study examined the trends in mortality and contributing adverse events associated with death under surgical care for patients with oesophageal cancer. METHODS: Adverse events in surgical care were prospectively audited in patients who died with cancer of the oesophagus or oesophago-gastric junction under surgical care in Scotland from 1994 to 2005 through the Scottish Audit of Surgical Mortality (SASM). RESULTS: Between 1994 and 2005 (inclusive), 1424 patients with oesophageal cancer (median age 72, 62% male) died. The proportion of oesophageal cancer patients dying on a surgical ward fell significantly from 17% to 13% (p = 0.005). There has been a significant decrease in the annual number of major surgical resections for oesophageal cancer in Scotland from 324 in 1994 to 193 in 2005 (p < 0.001). The proportion of patients operated on in specialist cancer centres increased since 2000. In the period 1996 to 2005, 1157 patients died under surgical care with oesophageal cancer and were audited by SASM. One hundred and thirty five patients (12%) had 239 adverse events. Overall, the number of adverse events decreased over time with 65/130 of those who died following a cancer resection had adverse events. An anastomotic leak was a factor in 25 of these patients. There was a significant decrease in the proportion of deaths following therapeutic endoscopy (p = 0.011). CONCLUSION: There has been a significant decrease in the number of cancer resections, adverse events and mortality associated with oesophageal cancer surgery at a time of increasing surgical specialisation.

A lipoma of the small bowel mesentery is a rare pathological entity. It has been shown to rarely cause obstruction and volvulus of the small bowel. We report a case of a 72-year-old man who presented with lower abdominal pain and slightly raised inflammatory markers. Computerized tomography of the abdomen showed small bowel perforation and oedematous terminal ileum. At laparotomy the cause was found to be a mesenteric lipoma causing small bowel perforation. As far as the authors are aware, this presentation is not described in the English language literature.

Limited data exist on allogeneic transplant outcomes in recipients receiving hematopoietic cells from donors with prior or current hepatitis B (HBV) or C virus (HCV) infection (seropositive donors), or for recipients with prior or current HBV or HCV infection (seropositive recipients). Transplant outcomes are reported for 416 recipients from 121 centers, who received a human leukocyte antigen-identical related-donor allogeneic transplant for hematologic malignancies between 1995 and 2003. Of these, 33 seronegative recipients received grafts from seropositive donors and 128 recipients were seropositive. The remaining 256 patients served as controls. With comparable median follow-up (cases, 5.9 years; controls, 6.7 years), the incidence of treatment-related mortality, survival, graft-versus-host disease, and hepatic toxicity, appears similar in all cohorts. The frequencies of hepatic toxicities as well as causes of death between cases and controls were similar. Prior exposure to HBV or HCV in either the donor or the recipient should not be considered an absolute contraindication to transplant.

The Capillary Morphogenesis Gene 2 (CMG2) gene encodes an Anthrax toxin receptor (ANTXR2), but the normal physiological function is not known. ANTXR2/CMG2 was originally identified as a result of up-regulation during capillary morphogenesis of endothelial cells (ECs) cultured in vitro. We explored the hypothesis that key steps of the angiogenic process are either dependent or are influenced by ANTXR2/CMG2 activity. We describe the expression pattern of ANTXR2/CMG2 in several murine tissues and in normal breast and breast tumors. Endothelial expression was found in all of the tissues analyzed, in cultured ECs and in breast tumor vessels; however, ANTXR2/CMG2 expression was not restricted to this cell type. To assess potential angiogenic function, we used RNA interference to achieve significant reduction of ANTXR2/CMG2 expression in cultured human umbilical venous endothelial cells (HUVECs). Reduced ANTXR2/CMG2 expression resulted in significant inhibition of proliferation and reduced capacity of ECs to form capillary-like networks in vitro, whereas overexpression of ANTXR2/CMG2 in HUVEC increased proliferation and capillary-like network formation. Little change in migration of ECs was observed on knockdown or overexpression. We conclude that ANTXR2/CMG2 functions to promote endothelial proliferation and morphogenesis during sprouting angiogenesis, consistent with the endothelial expression of ANTXR2/CMG2 in several vascular beds.

Non-myeloablative (NMA) allogeneic donor SCT for patients with relapsed lymphoma is associated with lower treatment-related mortality (TRM). However, the impact of conditioning intensity on post transplant infections remains unclear. We evaluated infections in 141 consecutive patients with lymphoma who were allografted using NMA (n=76) or myeloablative (MA; n=65) conditioning regimens. Using infection incidence density per 1000 patient days, we accounted for all infectious episodes during the first post transplant year. Before neutrophil engraftment, the NMA cohort had a 53% lower rate of bacterial infection (relative risk=0.47; P=0.06), whereas after engraftment the density of bacterial infections was similar in the two groups. In the first month, both invasive fungal infections and viral infections were twofold less frequent (P=0.22; P=0.06) in NMA patients. Late viral and fungal infections as well as CMV reactivation were infrequent after either conditioning intensity. The 1-year infection-related mortality was significantly lower after NMA conditioning (NMA 9% (3-16%) vs MA 22% (11-40%); P=0.03). NMA allogeneic transplantation for lymphoma patients results in substantially fewer early infections and lower infection-related deaths, although the similar frequency of later infections suggests that immune reconstitution is delayed with either conditioning intensity.

We describe herein 98 hematopoietic stem cell transplant (HSCT) recipients with invasive aspergillosis (IA) (refractory in 83) who received micafungin either alone (8 patients) or in combination with other licensed antifungal therapies (OLAT) (90 patients). Of the 8 monotherapy patients, 4 were failing OLAT, received de novo micafungin, or were intolerant to prior OLAT (2 patients each). Of the 90 patients treated with combination, 7 had de novo IA and 83 had refractory infection. Most patients (81) had pulmonary IA, 42 (43%) had graft-versus-host disease (GVHD), and 26 (27%) were neutropenic (absolute neutrophil count <500 cells/mm(3)) at onset of treatment. Successful response was seen in 25/98 (26%); an additional 12 patients achieved stable disease. Response was seen in 2/9 (22%) in de novo treatment, 21/87 (24%) in refractory patients, and 2/2 (100%) in toxicity failure patients. Additionally, response was seen in 22 of the 90 (24%) patients treated with combination therapy, and in 3 of 8 (38%) patients who were treated with micafungin alone. No significant differences in responses were found based on type of HSCT, GVHD status, site of IA, or Aspergillus species, and no significant toxicity was seen. Micafungin was well tolerated, even at high doses, and is a reasonable option for treatment of IA in this high-risk patient population.
