The impact of the Shanley Pressure Ulcer Prevention Programme on older persons' knowledge of,and attitudes and behaviours towards,pressure ulcer prevention

Pressure ulcers (PUs) have a profound impact on individuals, with studies demonstrating that compared with similarly aged persons, those living with a PU have a significantly lower quality of life. The aim of this study was to explore the impact of the Shanley Pressure Ulcer Prevention Programme (SPUPP) on older persons'' knowledge of, and attitudes and behaviours towards, PU prevention. This was a multi‐centre, open‐label, randomised controlled trial. The population of interest was older persons living in the community who attended either a day care centre or a retirement group and were deemed to be at risk of PUs due to reduced mobility. Stratified random sampling was used to randomise based on days of attendance at day care centre/retirement group. Pretest and post‐test were applied to the intervention and control groups. The SPUPP is a multimedia programme delivered using electronic media, hard copy materials, activities, and patient diaries and addresses the key tenets of PU prevention as described by the SKIN bundle. The programme contains five separate sessions delivered over 5 weeks. The impact of the SPUPP was assessed using the patient knowledge of and attitude and behaviour towards PU prevention instrument (KPUP). A total of 64 persons, 32 in each group, took part in the study. Of these, 75% (n = 48) were female, with a mean age of 81.9 years (SD: 5.56 years). Further, 68.8% (n = 44) were either overweight or obese and 40.6% (n = 26) were usually incontinent of urine. There were no differences between the intervention and control groups in mean scores during the pretest stage. However, at post‐test, the mean scores for the intervention group were higher than the control group, 16.87 (SD: 1.88) versus 12.41 (SD: 3.21), respectively. For the post‐test stage, mean differences between the two groups in favour of the intervention group (∆ = 4.46) were statistically significant, as t = 6.76, P = .0001, and equal variances were not assumed. The SPUPP impacted positively on knowledge scores of the participants and positively influenced attitudes and behaviours towards PU prevention. Thus, this research provides information regarding the potential to enhance patient involvement in PU prevention.     

Paraplegia after thoracic aortic occlusion: influence of cerebrospinal fluid drainage. Experimental and early clinical results

Paraplegia occurs in 6.5% to 40% of patients after repair of extensive thoracoabdominal aortic aneurysms requiring aortic clamping. This study aimed to determine whether drainage of cerebrospinal fluid (CSF) done before aortic cross-clamping could decrease the incidence of paraplegia in dogs. The descending thoracic aorta was clamped distal to the left subclavian artery for either 40 minutes (group I) or 60 minutes (group II). All control animals in group I (10) and group II (10) showed evidence of spinal cord injury with paraparesis or paraplegia. In contrast, 9 of 10 animals (90%) in group I and 7 of 10 animals (70%) in group II that had CSF drainage before aortic cross-clamping were neurologically normal (p less than 0.001 and p less than 0.01, respectively). Aortic pressure distal to the aortic cross clamp was the same in all groups; however, spinal cord perfusion pressure (distal aortic pressure minus CSF pressure) was significantly higher in neurologically normal animals (34 +/- 5 mm Hg, n = 15) compared with those with paraparesis (26 +/- 4 mm Hg, n = 8) or paraplegia (19 +/- 5 mm Hg, n = 8) (r = 0.871, p less than 0.001). This study demonstrates that drainage of CSF before thoracic aortic occlusion significantly increases spinal cord perfusion pressure and decreases the incidence of paraplegia. Limited early clinical experience suggests that CSF drainage may be a useful adjunct to prevent paraplegia in patients who are having repair of thoracoabdominal aortic aneurysms.     

Fibrin glue sealing of polytetrafluoroethylene vascular graft anastomoses: comparison with oxidized cellulose

To evaluate potential clinical applications of nonautologous fibrin glue (FG) as a hemostatic agent in vascular surgery, we compared its efficacy to oxidized regenerated cellulose (OC) in hemostatically sealing polytetrafluoroethylene (PTFE) vascular graft anastomoses. PTFE grafts (4 mm wide and 4 to 6 cm in length) were placed to each femoral artery in a heparinized canine model, in end-to-end fashion in half of the dogs and in end-to-side fashion in the remaining dogs. Each set of graft-arterial anastomoses was then sealed with either FG or OC, determined randomly, followed by simultaneous measurement of blood loss through the graft anastomoses and needle holes. There was significantly less bleeding from anastomoses sealed with FG compared with those sealed with OC, regardless of whether the anastomoses sealed with FG compared with those sealed with OC, regardless of whether the anastomosis was constructed in end-to-end (p less than 0.03) or end-to-side (p less than 0.004) fashion; overall, the operative blood loss for grafts sealed with FG was 14 +/- 6 (mean +/- standard error of the mean) vs 99 +/- 27 ml/min for those sealed with OC (p less than 0.001). In the early postoperative period, significant groin hematomas occurred more frequently in grafts sealed with OC compared with those sealed with FG. Microscopic examination of graft-arterial specimens harvested at postoperative intervals ranging from 1 day to 3 months revealed no significant inflammatory reaction with either hemostatic agent; after 2 to 3 weeks, paired specimens appeared histologically similar despite previous treatment with either FG or OC.(ABSTRACT TRUNCATED AT 250 WORDS)     

Utilization,Patient Characteristics,and Longitudinal Improvements among Patients from a Provincially Funded Transdiagnostic Internet-delivered Cognitive Behavioural Therapy Program: Observational Study of Trends over 6 Years

Objective:There is strong evidence supporting internet-delivered cognitive behaviour therapy (iCBT) and consequently growing demand for iCBT in Canada. Transdiagnostic iCBT that addresses both depression and anxiety is particularly promising as it represents an efficient method of delivering iCBT in routine care. The Online Therapy Unit, funded by the Saskatchewan government, has been offering transdiagnostic iCBT for depression and anxiety since 2013. In this article, to broadly inform implementation efforts, we examined trends in utilization, patient characteristics, and longitudinal improvements for patients receiving transdiagnostic iCBT over 6 years.Methods:Patients who completed telephone screening between November 2013 and December 2019 were included in this observational study. Patients provided demographics and mental health history at screening and completed measures at pre-treatment, post-treatment and at 3- to 4-month follow-up. Treatment engagement and satisfaction were assessed.Results:A total of 5,321 telephone screenings were completed and 4,283 of patients were accepted for treatment over the 6-year period (80.5% acceptance). The most common reason for referral to another service was high suicide risk/severe symptoms (47.1%). Examination of trends showed growing use of transdiagnostic iCBT over time (37% increase per year). There was remarkable stability in patient characteristics across years. Most patients were concurrently using medication (57.3%) with 11.9% reporting using iCBT while on a waiting list for face-to-face treatment highlighting the importance of integrating iCBT with other services. Consistent across years, large improvements in depression and anxiety symptoms were found and maintained at 3- to 4-month follow-up. There was strong patient engagement with iCBT and positive ratings of treatment experiences.Conclusions:As there is growing interest in iCBT in Canada, this large observational study provides valuable information for those implementing iCBT in terms of likely user characteristics, patterns of use, and improvements. This information has potential to assist with resource allocation and planning in Canada and elsewhere.     

Alternatives to HIV-1 RNA concentration and CD4 count to predict mortality in HIV-1-infected children in resource-poor settings

Cheaper, simpler alternatives to CD4 lymphocyte count and HIV-1 RNA detection for assessing the prognosis of HIV-1 infection are needed for resource-poor settings. However, little is known about the predictive value of alternative assays, in particular in children. We assessed the prognostic value of total lymphocyte count, immune complex-dissociated p24 antigen, white blood cell count, packed-cell volume (haematocrit), and serum albumin for mortality in 376 HIV-1-infected, mainly African-American or Hispanic children enrolled during March, 1988 to January, 1991. In a Cox proportional hazards model, including all assay-alternatives to CD4 and RNA, total lymphocyte count (p<0.0001) and serum albumin (p=0.0107) independently predicted mortality. Further assessment of these markers is warranted in resource-poor settings.     

Lawnmower injuries in children.

OBJECTIVE: Power lawnmowers can pose significant danger of injury to both the operator and the bystander, from direct contact with the rotary blades or missile injury. Our objective was to review our experience with paediatric lawnmower-associated trauma, and the safety recommendations available to operators of power lawnmowers. METHODS: The patient cohort comprised paediatric (<16 years of age) patients treated for lawnmower-associated trauma, by the plastic surgery service, between 1996 and 2003. These patients were identified retrospectively. Age at the time of injury, location and extent of bony and soft tissue injuries sustained, treatment instituted and clinical outcome were recorded. Brochures and instruction manuals of six lawnmower manufacturers were reviewed, and safety recommendations noted. RESULTS: Fifteen patients were identified. The majority of injuries occurred from direct contact with the rotary blades (93%); the remaining child sustained a burn injury. Fourteen children (93%) required operative intervention. Seven patients (46%) sustained injuries resulting in amputation, two of whom had major limb amputations. All children, except the burns patient, underwent wound debridement and received antibiotic therapy. Reconstructive methods ranged from primary closure to free tissue transfer. Many patients required multiple procedures. In all instruction manuals, instructions to keep children and pets indoors or out of the yard when mowing were found. CONCLUSIONS: Lawnmower injuries can be devastating, particularly in children. Many victims have lasting deformities as a result of their injuries. Awareness of and stringent adherence to safety precautions during use of power lawnmowers can prevent many of these accidents.     

Chronic glucocorticosteroid therapy impairs staphylococcal clearance from murine lungs.

Since the clearance of Staphylococcus aureus from murine lungs after aerosol exposure depends only on regional defense processes and does not require the recruitment of neutrophils or other systemic factors, we used this model for pulmonary clearance to evaluate the effect of chronic glucocorticosteroid therapy on intrinsic pulmonary defense responses. Mice treated with oral prednisolone for 2 or more weeks had delayed clearance of S. aureus at both 6 and 22 h after aerosol exposure. Mice treated with prednisolone for 1 week had delayed clearance at 22h, and mice treated for 2 days had normal clearance. In mice that had been treated for 2 weeks, clearance returned to normal after 2 weeks off therapy, but not after 1 week. Prednisolone did not appear to alter the number of phagocytes in bronchoalveolar spaces or their ingestion capacity. These results suggest that chronic steroid therapy can alter pulmonary clearance functions independent of any effect on immune or inflammatory responses.     

eHealth for neonatal nurse education despite Covid-19

AimThe aim of this contemporary issue paper is to challenge the premise that the term “eHealth” is relatable to patient or service users only. It will be critically explored if the term can be broadened to include neonatal nurse education interventions.DesignA review of current literature will form the basis for the critical discussion of the term eHealth, and why it can be associated with neonatal nurse education.MethodsThe critical discussion will identify and review past and current literature relating to eHealth and its origins. It will portray the viability of the term eHealth as more than just a patient associated intervention, and why it should also be encompassed as a neonatal nurse education option.ConclusioneHealth is traditionally identifiable as a service user intervention or source of information. The term should be broadened to encompass neonatal nurse education and used as a resource that is easily accessible and user friendly. This will in turn encourage the personal and professional development of neonatal nurses and should ultimately contribute to evidence based best practices in the clinical environment, despite the current global pandemic.
