Abstract: Objective: This pragmatic randomized study was conducted to compare the effectiveness of telephone and face-to-face counseling in influencing problematic gambling beliefs and behaviors. Method: Ninety-two participants from erse ethnic backgrounds who had been affected by problem gambling were provided with psychological interventions delivered either by telephone or conventional face-to-face counseling over a 3-month period. Results: A significant overall time effect between pre- and postintervention assessments was found for total hours, money and proportion of income spent, and the attitudes and beliefs scores. There was no significant difference in effect size between the two groups. Conclusion: This study provides preliminary evidence that both face-to-face and telephone counseling interventions might be equally effective in terms of short-term clinical outcomes measured postintervention.

Abstract: To assess the safety and efficacy of avoiding endotracheal suction in postoperative cardiac surgical patients mechanically ventilated for ≤ 12 hr. A prospective, single centre, single blind, non-inferiority, randomized controlled trial evaluating the safety and efficacy of avoiding suction in uncomplicated, postoperative, adult cardiac surgical patients mechanically ventilated for ≤ 12 hr. Randomization will be performed on return to intensive care (ICU) with allocation to either usual postoperative care including suction or to usual care with no suction (intervention arm). The primary outcome is the ratio of partial pressure of oxygen (PaO Endotracheal suction is performed as part of airway management but has potential complications and there is little robust evidence to guide practice. This study will add to the evidence base about the need and benefit of endotracheal suction in this patient cohort. As there is currently no published evidence about the safety of avoiding endotracheal suction. This study will provide the first evidence about avoidance of endotracheal suction in patients ventilated for less than 1 day. If non-inferior, the results have the capacity to change nursing practice by avoiding a potentially unnecessary procedure, it will build on the body of knowledge about the patient experience.

Abstract: Postoperative respiratory complications following cardiac surgery may increase morbidity, mortality and length of stay. Non-invasive respiratory support therapies can be used prophylactically or curatively to reduce respiratory complications. One system, nasal high flow oxygen therapy, is in use in many intensive care units (ICUs) however there is a lack of information regarding its clinical utility and efficacy. This paper outlines the study protocol and methodology for a study designed to determine if the prophylactic use of nasal high flow oxygen therapy can improve pulmonary function in patients following cardiac surgery. A prospective randomised controlled trial will be conducted of adult patients scheduled for cardiac surgery and admitted to the Cardiothoracic Intensive Care Unit of a tertiary hospital. Study participants will be assigned to receive either nasal high flow or standard oxygen therapy (oxygen therapy at 2-4 L/min via either simple facemask or nasal cannulae) at extubation. The primary outcome measure is improved pulmonary function demonstrated by SpO2/FiO2 ratio >445 on post-operative day 3. Secondary outcome measures include atelectasis score on chest X-ray spirometry readmission to ICU for respiratory causes ICU and hospital length of stay mortality and incidence of respiratory complications at day 28 oxygenation variables use of adjunctive respiratory support therapies escalation of respiratory support adverse events and patient comfort during administration of oxygen therapy. It was calculated that 340 patients will be required--170 per arm of study--to give a 90% power to detect a 15% treatment effect. This study started recruiting in March 2011. It is anticipated that enrollment will be complete in April 2012 and results available towards the end of 2012. This study will provide evidence of any benefits in the use of prophylactic nasal high flow therapy in post-operative cardiac surgical patients.

Abstract: Childhood obesity has reached epidemic proportions in developed countries. Sedentary screen-based activities such as video gaming are thought to displace active behaviors and are independently associated with obesity. Active video games, where players physically interact with images onscreen, may have utility as a novel intervention to increase physical activity and improve body composition in children. The aim of the Electronic Games to Aid Motivation to Exercise (eGAME) study is to determine the effects of an active video game intervention over 6 months on: body mass index (BMI), percent body fat, waist circumference, cardio-respiratory fitness, and physical activity levels in overweight children. Three hundred and thirty participants aged 10–14 years will be randomized to receive either an active video game upgrade package or to a control group (no intervention). An overview of the eGAME study is presented, providing an ex le of a large, pragmatic randomized controlled trial in a community setting. Reflection is offered on key issues encountered during the course of the study. In particular, investigation into the feasibility of the proposed intervention, as well as robust testing of proposed study procedures is a critical step prior to implementation of a large-scale trial.

Abstract: Compression is the mainstay of treatment for venous leg ulcers (VLUs) and there are few effective adjuvant treatments. There is only observational evidence supporting the use of hypochlorous acid (HOCl) as a topical wound solution on VLU and some limited randomised evidence for the effect of a prescribed regimen of exercise. The Factorial4VLU trial is a pragmatic, blinded, factorial randomised controlled trial, with 380 participants receiving either a prescribed exercise regimen compared with usual care and either active HOCl wound solution or placebo wound solution at each dressing change for up to 24 weeks. All participants will receive compression therapy. The primary outcome is the proportion of participants with healed VLU at 12 weeks after randomisation as adjudicated by blinded review of ulcer photographs. Secondary outcomes are proportion healed at 24 weeks, time to healing, estimated change in ulcer area, change in 2-Minute Walk Test, change in health-related quality of life, incidence of infection and incidence of all-cause adverse events. If either of the interventions shows a statistically significant positive difference on healing outcomes, cost-effectiveness will be modelled using a health service perspective. The Factorial4VLU trial received ethical approval from the Northern B Health and Disability Ethics Committee. We plan to publish the results within 1 year of trial completion and will include the results on the trial registration page.

Abstract: The efficacy of honey as a treatment for venous ulcers has not been evaluated, despite widespread interest. This trial aimed to evaluate the safety and effectiveness of honey as a dressing for venous ulcers. This community-based open-label randomized trial allocated people with a venous ulcer to calcium alginate dressings impregnated with manuka honey or usual care. All participants received compression bandaging. The primary outcome was the proportion of ulcers healed after 12 weeks. Secondary outcomes were: time to healing, change in ulcer area, incidence of infection, costs per healed ulcer, adverse events and quality of life. Analysis was by intention to treat. Of 368 participants, 187 were randomized to honey and 181 to usual care. At 12 weeks, 104 ulcers (55·6 per cent) in the honey-treated group and 90 (49·7 per cent) in the usual care group had healed (absolute increase 5·9 (95 per cent confidence interval (c.i.) − 4·3 to 15·7) per cent P = 0·258). Treatment with honey was probably more expensive and associated with more adverse events (relative risk 1·3 (95 per cent c.i. 1·1 to 1·6) P = 0·013). There were no significant differences between the groups for other outcomes. Honey-impregnated dressings did not significantly improve venous ulcer healing at 12 weeks compared with usual care.

Abstract: Despite the evidence and available guidelines about endotracheal suction (ETS), a discrepancy between published guidelines and clinical practice persists. To date, ETS practice in the adult intensive care unit (ICU) population across New Zealand and Australia has not been described. To describe ICU nurses' ETS practice in New Zealand and Australia including the triggers for performing endotracheal suction. A single day, prospective observational, binational, multicentre point prevalence study in New Zealand and Australian ICUs. All adult patients admitted at 10:00 on the study day were included. In addition to patient demographic data, we assessed triggers for ETS, suction canister pressures, use of preoxygenation, measures of oxygenation, and ETS at extubation. There were 682 patients in the ICUs on the study day, and 230 were included in the study. Three of 230 patients were excluded for missing data. A total of 1891 ETS events were performed on 227 patients during the study day, a mean of eight interventions per patient. The main triggers reported were audible (n = 385, 63%) and visible (n = 239, 39%) secretions. Less frequent triggers included following auscultation (n = 142, 23%), reduced oxygen saturations (n = 140, 22%), and ventilator waveforms (n = 53, 9%). Mean suction canister pressure was -337 mmHg (standard deviation = 189), 67% of patients received preoxygenation (n = 413), and ETS at extubation was performed by 84% of nurses. Some practices were inconsistent with international guidelines, in particular concerning patient assessment for ETS and suction canister pressure.

Abstract: To determine the effect of a keratin dressing for treating slow-to-heal venous leg ulcers (VLU) on VLU healing. Pragmatic parallel group randomised controlled trial. Community-dwelling participants. People aged 18 or more years with VLU (either present for more than 26 weeks or ulcer area larger than 5 cm 2 or both). Wool-derived keratin dressing or usual care formulary of non-medicated dressings, on a background treatment with compression. Healing at 24 weeks based on blinded assessment of ulcer photographs. Other outcomes included time to complete healing, change in ulcer area to 24 weeks, change in health-related quality of life and incidence of adverse events. We screened 1068 patients with VLU and randomised 143 participants (51.1% of target recruitment), 71 to the keratin dressing group and 72 to the usual care group.The mean age was 66.1 years (SD 15.9) and 53 participants (37.1%) were women. There were no significant differences between the groups on the primary outcome (risk difference −6.4%, 95% CI −22.5% to 9.7%), change in ulcer area (−1.9 cm 2 , 95% CI −16.5 to 12.8 cm 2 ), time to complete healing (HR 0.80, 95% CI 0.52 to 1.23) or the incidence of adverse events (incidence rate ratio 1.19, 95% CI 0.89 to 1.59) in the intention-to-treat analyses. However, the direction of effect on the primary outcome was reversed in a per protocol analysis specified a priori (risk difference 6.2%, 95% CI −12.4% to 24.9%). The effect of adding a keratin dressing to the treatment regimen for prognostically slow-to-heal VLU remains unclear. NCT02896725

Abstract: Sedentary activities such as video gaming are independently associated with obesity. Active video games, in which players physically interact with images on screen, may help increase physical activity and improve body composition. The aim of this study was to evaluate the effect of active video games over a 6-mo period on weight, body composition, physical activity, and physical fitness. We conducted a 2-arm, parallel, randomized controlled trial in Auckland, New Zealand. A total of 322 overweight and obese children aged 10-14 y, who were current users of sedentary video games, were randomly assigned at a 1:1 ratio to receive either an active video game upgrade package (intervention, n = 160) or to have no change (control group, n = 162). The primary outcome was the change from baseline in body mass index (BMI in kg/m(2)). Secondary outcomes were changes in percentage body fat, physical activity, cardiorespiratory fitness, video game play, and food snacking. At 24 wk, the treatment effect on BMI (-0.24 95% CI: -0.44, -0.05 P = 0.02) favored the intervention group. The change (±SE) in BMI from baseline increased in the control group (0.34 ± 0.08) but remained the same in the intervention group (0.09 ± 0.08). There was also evidence of a reduction in body fat in the intervention group (-0.83% 95% CI: -1.54%, -0.12% P = 0.02). The change in daily time spent playing active video games at 24 wk increased (10.03 min 95% CI: 6.26, 13.81 min P < 0.0001) with the intervention accompanied by a reduction in the change in daily time spent playing nonactive video games (-9.39 min 95% CI: -19.38, 0.59 min P = 0.06). An active video game intervention has a small but definite effect on BMI and body composition in overweight and obese children. This trial was registered in the Australian New Zealand Clinical Trials Registry at www.anzctr.org.au/ as ACTRN12607000632493.
