Pressure ulcer healing with an intensive nutrition intervention in an acute setting: a pilot randomised controlled trial

OBJECTIVE

To investigate the feasibility of recruitment, retention, intervention delivery and outcome measurement in a nutritional intervention to promote pressure ulcer healing in an acute setting.

METHOD

Some 50 tertiary hospital patients with stage II or greater pressure ulcer were randomised to receive either individualised nutritional care by a dietitian, including prescription of wound healing supplements; or standard nutritional care. Relevant nutritional and pressure ulcer (PU) parameters were collected at day 5, 10, 15, 22 and then weekly or until discharge.

RESULTS

The median length of hospital stay was 14 days (1-70) with 29 patients discharged by day 15. There were 24 patients discharged before their PU fully healed. Per cent change in valid PU area and score measures from baseline to day 15 were chosen for outcome data analysis to account for varying initial size and severity of the wound and length of stay. There was a larger percentage reduction in PU measures in the intervention group, but this was not statistically significant. Little difference was found in nutritional intake between the control and intervention groups indicating a requirement to focus on effective delivery of the intervention in future studies. Future studies in the acute setting need to account for length of stay and ideally follow patients until full healing.

CONCLUSION

Results indicate a positive association with nutrition intervention and PU healing and that a rigorously designed and adequately powered study is feasible.

Intervention-related increases in preoperative physical activity are maintained 6-months after Bariatric surgery: results from the bari-active trial

Higher preoperative physical activity (PA) strongly predicts higher post-operative PA in bariatric surgery (BS) patients, providing rationale for preoperative PA interventions (PAIs). However, whether PAI-related increases can be maintained post-operatively has not been examined. This study compared PA changes across pre- (baseline, post-intervention) and post-operative (6-month follow up) periods in participants randomized to 6 weeks of preoperative PAI or standard care control (SC). Of 75 participants initially randomized, 36 (PAI n=22; SC n=14) underwent BS. Changes in daily bout-related (⩾10-min bouts) moderate-to-vigorous PA (MVPA) and steps were assessed via the SenseWear Armband monitor. PAI received weekly counseling to increase walking exercise. Retention (86%) at post-operative follow up was similar between groups. Intent-to-treat analyses showed that PAI vs SC had greater increases across time (baseline, post-intervention, follow up) in bout-related MVPA minutes/day (4.3±5.1, 26.3±21.3, 28.7±26.3 vs 10.4±22.9, 11.4±16.0, 18.5±28.2; P=0.013) and steps/day (5163±2901, 7950±3286, 7870±3936 vs 5163±2901, 5601±3368, 5087±2603; P<0.001). PAI differed from SC on bout-related MVPA at post-intervention (P=0.016; d=0.91), but not follow up (P=0.15; d=0.41), and steps at post-intervention (P=0.031; d=0.78) and follow up (P=0.024; d=0.84). PAI participants maintained preoperative PA increases post-operatively. Findings support preoperative PAIs and research to test whether PA changes can be sustained and influence surgical outcomes beyond the initial post-operative period.

Beta-Interferon Use in Multiple Sclerosis: Audit of Practice in Grampian

Beta-interferon was licensed for the treatment of multiple sclerosis in 1996. Since then it has been a controversial therapy. Availability of treatment has been varied from region to region. We audited the use of beta-interferon in the Grampian region, which has the largest cohort of patients treated in Scotland. One hundred and thirty seven patients were treated up to the beginning of 2002, 12.5% of the local MS population. The number of patients given treatment in Grampian continues to increase. Very few patients have discontinued treatment. The results of this audit show that our patients were treated in line with current clinical guidelines. This has implications for the implementation of guidelines in the rest of Scotland, where much smaller numbers of patients have been treated thus far. (127)

Shifting from presumptive to test-based management of malaria - technical basis and implications for malaria control in Ghana

The presumptive approach was the World Health Organisation (WHO) recommended to the management of malaria for many years and this was incorporated into syndromic guidelines such as the Integrated Management of Childhood Illnesses (IMCI). In early 2010 however, WHO issued revised treatment guidelines that call for a shift from the presumptive to the test-based approach. Practically, this implies that in all suspected cases, the diagnosis of uncomplicated malaria should be confirmed using rapid test before treatment is initiated. This revision effectively brings to an end an era of clinical practice that span several years. Its implementation has important implications for the health systems in malaria-endemic countries. On the basis of research in Ghana and other countries, and evidence from program work, the Ghana National Malaria Control Program has issued revised national treatment guidelines that call for implementation of test-based management of malaria in all cases, and across all age groups. This article reviews the evidence and the technical basis for the shift to test-based management and examines the implications for malaria control in Ghana.

Durability and complications of photoselective vaporisation of the prostate with the 120W high performance system GreenLight™ lithium triborate laser

INTRODUCTION

The aim of this study was to examine the durability of photoselective vaporisation of the prostate (PVP) with the 120W GreenLight HPS(®) laser (American Medical Systems, Minnetonka, MN, US), and to examine the incidence, nature and factors associated with complications from the procedure.

METHODS

Clinical records of PVP patients were reviewed to compare details between patients who developed complications and those who did not. Kaplan-Meier survival curves were used to assess durability. Cox regression was used to examine associations between complications and perioperative factors.

RESULTS

Successful outcomes were maintained in 84% of 117 patients at the 2-year follow-up appointment. Complication rates were low and comparable with transurethral resection of the prostate (TURP). Complications were developed by 18 patients (15.4%) over a mean follow-up duration of 20.8 months. The most common complications were residual prostate requiring another surgery (5/117, 4.3%) and urethral stricture (4/117, 3.4%). Patients with complications had significantly longer catheterisation duration. Length of hospital stay, lasing energy, pre and postoperative levels of prostate specific antigen (PSA), pre and postoperative maximum flow rate (Qmax), and age at surgery were not found to influence development of complications.

CONCLUSIONS

Results from PVP with an HPS(®) laser are durable. Complications are low and compare favourably with TURP. Lasing energy, PSA, Qmax, patient age and length of stay are not associated with development of complications. However, a longer postoperative catheterisation after PVP is associated with development of complications.

Monitoring the levels of important nutrients in the food supply

A food supply that delivers energy-dense products with high levels of salt, saturated fats and trans fats, in large portion sizes, is a major cause of non-communicable diseases (NCDs). The highly processed foods produced by large food corporations are primary drivers of increases in consumption of these adverse nutrients. The objective of this paper is to present an approach to monitoring food composition that can both document the extent of the problem and underpin novel actions to address it. The monitoring approach seeks to systematically collect information on high-level contextual factors influencing food composition and assess the energy density, salt, saturated fat, trans fats and portion sizes of highly processed foods for sale in retail outlets (with a focus on supermarkets and quick-service restaurants). Regular surveys of food composition are proposed across geographies and over time using a pragmatic, standardized methodology. Surveys have already been undertaken in several high- and middle-income countries, and the trends have been valuable in informing policy approaches. The purpose of collecting data is not to exhaustively document the composition of all foods in the food supply in each country, but rather to provide information to support governments, industry and communities to develop and enact strategies to curb food-related NCDs.
