There has been growing interest in the use of smart wearable technology to promote physical activity (PA) behaviour change. However, little is known concerning PA patterns throughout an intervention ...or engagement with trackers. The objective of the study was to explore patterns of Fitbit-measured PA and wear-time over 24-weeks and their relationship to changes in Actigraph-derived moderate-to-vigorous PA (MVPA).
Twenty-nine intervention participants (88%) from the wearable activity technology and action-planning (WATAAP) trial in colorectal and endometrial cancer survivors accepted a Fitbit friend request from the research team to permit monitoring of Fitbit activity. Daily steps and active minutes were recorded for each participant over the 12-week intervention and throughout the follow-up period to 24-weeks. Accelerometer (GT9X) derived MVPA was assessed at end of intervention (12-weeks) and end of follow-up (24-weeks).
Fitbit wear-time over the 24-weeks of data was remarkably consistent, with median adherence score of 100% for all weeks. During the intervention, participants recorded a median 8006 steps/day. Daily step count was slightly increased through week-13 to week-24 with a median of 8191 steps/day (p = 0.039). Actigraph and Fitbit derived measures were highly correlated but demonstrated poor agreement overall. Fitbit measured activity was closest to MVPA measured using Freedson cut-points as no bias was observed.
Step count was maintained throughout the trial displaying promise for the effectiveness of smart-wearable interventions to reduce sedentary behaviour beyond the intervention period. Further worthwhile work should compare more advanced smart-wearable technology with accelerometers in order to improve agreement and explore less resource-intensive methods to assess PA that could be scalable.
Background:
A previously published trial showed that patients with chronic gluteal tendinopathy achieved greater clinical improvement at 12 weeks when treated with a single platelet-rich plasma (PRP) ...injection than those treated with a single corticosteroid injection (CSI).
Purpose:
This follow-up study was conducted to determine whether there would be a sustained long-term difference in the modified Harris Hip Score (mHHS) at 2 years for a leucocyte-rich PRP (LR-PRP) injection in the treatment of chronic gluteal tendinopathy.
Study Design:
Randomized controlled trial; Level of evidence, 1.
Methods:
This trial included 80 patients randomized 1:1 to receive LR-PRP or CSI intratendinously under ultrasound guidance. Patients had a mean age of 60 years, a 9:1 ratio of women to men, a mean body mass index of 27, and a mean length of symptoms >15 months. No patients had full-thickness tears of the gluteal tendons. An open-labeled extension allowed patients to receive crossover treatment after 3 months. The main outcome measure was the mHHS.
Results:
The mean mHHS improved significantly at 12 weeks in the PRP group (74.05; SD, 13.92) as compared with the CSI group (67.13; SD, 16.04) (P = .048). At 24 weeks, the LR-PRP group (77.60; SD, 11.88) improved further than the CSI group (65.72; SD, 15.28; P = .0003). Twenty-seven patients were deemed to have failed the CSI treatment at 16 to 24 weeks, with an exit score of 59.22 (SD, 11.54), and then had treatment with LR-PRP. The crossover group improved with the LR-PRP: from 59.22 (SD, 11.22) at baseline to 75.55 (SD, 16.05) at 12 weeks, 77.69 (SD, 15.30) at 24 weeks, and 77.53 (SD, 14.54) at 104 weeks. The LR-PRP group retained 38 of 39 patients to 52 weeks and continued to improve. Their baseline scores of 53.77 (SD, 12.08) improved to 82.59 (SD, 9.71) at 104 weeks (P < .0001).
Conclusion:
Among patients with chronic gluteal tendinopathy and a length of symptoms >15 months, a single intratendinous LR-PRP injection performed under ultrasound guidance results in greater improvement in pain and function than a single CSI. The improvement after LR-PRP injection is sustained at 2 years, whereas the improvement from a CSI is maximal at 6 weeks and not maintained beyond 24 weeks.

Frailty and pain in hospitalised patients are associated with adverse clinical outcomes. However, there is limited data on the associations between frailty and pain in this group of patients. ...Understanding the prevalence, distribution and interaction of frailty and pain in hospitals will help to determine the magnitude of this association and assist health care professionals to target interventions and develop resources to improve patient outcomes. This study reports the point prevalence concurrence of frailty and pain in adult patients in an acute hospital. A point prevalence, observational study of frailty and pain was conducted. All adult inpatients (excluding high dependency units) at an acute, private, 860-bed metropolitan hospital were eligible to participate. Frailty was assessed using the self-report modified Reported Edmonton Frail Scale. Current pain and worst pain in the last 24 h were self-reported using the standard 0-10 numeric rating scale. Pain scores were categorised by severity (none, mild, moderate, severe). Demographic and clinical information including admitting services (medical, mental health, rehabilitation, surgical) were collected. The STROBE checklist was followed. Data were collected from 251 participants (54.9% of eligible). The prevalence of frailty was 26.7%, prevalence of current pain was 68.1% and prevalence of pain in the last 24 h was 81.3%. After adjusting for age, sex, admitting service and pain severity, admitting services medical (AOR: 13.5 95% CI 5.7-32.8), mental health (AOR: 6.3, 95% CI 1. 9-20.9) and rehabilitation (AOR: 8.1, 95% CI 2.4-37.1) and moderate pain (AOR: 3.9, 95% CI 1. 6-9.8) were associated with increased frailty. The number of older patients identified in this study who were frail has implications for managing this group in a hospital setting. This indicates a need to focus on developing strategies including frailty assessment on admission, and the development of interventions to meet the care needs of these patients. The findings also highlight the need for increased pain assessment, particularly in those who are frail, for more effective pain management.Trial registration: The study was prospectively registered (ACTRN12620000904976; 14th September 2020).
Background:
Gluteus medius/minimus tendinopathy is a common cause of lateral hip pain or greater trochanteric pain syndrome.
Hypothesis:
There would be no difference in the modified Harris Hip Score ...(mHHS) between a single platelet-rich plasma (PRP) injection compared with a corticosteroid injection in the treatment of gluteal tendinopathy.
Study Design:
Randomized controlled trial; Level of evidence, 1.
Methods:
There were 228 consecutive patients referred with gluteal tendinopathy who were screened to enroll 80 participants; 148 were excluded (refusal: n = 42; previous surgery or sciatica: n = 50; osteoarthritis, n = 17; full-thickness tendon tear, n = 17; other: n = 22). Participants were randomized (1:1) to receive either a blinded glucocorticoid or PRP injection intratendinously under ultrasound guidance. A pain and functional assessment was performed using the mHHS questionnaire at 0, 2, 6, and 12 weeks and the patient acceptable symptom state (PASS) and minimal clinically important difference (MCID) at 12 weeks.
Results:
Participants had a mean age of 60 years, a ratio of female to male of 9:1, and mean duration of symptoms of >14 months. Pain and function measured by the mean mHHS showed no difference at 2 weeks (corticosteroid: 66.95 ± 15.14 vs PRP: 65.23 ± 11.60) or 6 weeks (corticosteroid: 69.51 ± 14.78 vs PRP: 68.79 ± 13.33). The mean mHHS was significantly improved at 12 weeks in the PRP group (74.05 ± 13.92) compared with the corticosteroid group (67.13 ± 16.04) (P = .048). The proportion of participants who achieved an outcome score of ≥74 at 12 weeks was 17 of 37 (45.9%) in the corticosteroid group and 25 of 39 (64.1%) in the PRP group. The proportion of participants who achieved the MCID of more than 8 points at 12 weeks was 21 of 37 (56.7%) in the corticosteroid group and 32 of 39 (82%) in the PRP group (P = .016).
Conclusion:
Patients with chronic gluteal tendinopathy >4 months, diagnosed with both clinical and radiological examinations, achieved greater clinical improvement at 12 weeks when treated with a single PRP injection than those treated with a single corticosteroid injection.

IntroductionOsteoradionecrosis (ORN) of the mandible is a painful and debilitating condition occurring after radiotherapy to the head and neck to treat cancer. For decades, hyperbaric oxygen (HBO) ...has formed the mainstay of the early management of ORN. Literature about the efficacy of HBO is contentious. Recently, Oral and Maxillofacial surgical units in France and UK have trialled a combination of medications to treat ORN, also known as PENTOCLO (PENtoxifylline+TOcopherol±CLOdronate). This regime has shown promising results to date however randomised controlled trials in the area comparing HBO against PENTOCLO are lacking and there are no current trials registered in Europe, UK, Australia and the USA. The purpose of this pilot study is to generate a hypothesis that can be tested in large multi-centre controlled trials.Methods and analysisFor this pilot study we will recruit 16 patients who will be randomly allocated to one of either HBO or PENTOCLO. After a 4 week period of uniform ‘pre-treatment’ medication patients will be commenced on their allocated treatment. Standard follow-up examination, imaging and photographs will be taken and de-identified and then presented to two Oral and Maxillofacial surgeons for allocation of a Notani & Lyons classification score. Data for each patient will be tracked over the 18 months of treatment and follow-up. The results will then be analysed using descriptive statistics and all patients included in an intention to treat analysis.Ethics and disseminationEthical approval for this study has been granted by the South Metropolitan Health Service HREC (PRN RGS0000001193). Data generated by conducting this study will be uploaded to an open access repository in a de-identified form. Results from this study will be disseminated at national and international conferences as well as peer reviewed medical publications.Trial registration numberACTRN12618001099213; Pre-results.
This pilot study aimed to examine EVOLVE UK extra care housing tool in an Australian residential aged care minor refurbishment context. The tool's content validity was established with 34 ...subcategories (I-CVI ≥0.75) and 612 statements (n = 509 I-CVI ≥0.75) relevant. A subsequent audit indicated high concordance (Rho-C = 0.750 to 0.997) within four experts' ratings of the care facility and correlation (Kendall's τ-statistic) between raters ranged from strong (0.5 to 0.9) to very strong (0.9 to 1.0). Lighting was the highest refurbishment element represented (50.54%). Assessment can inform funding, demonstrate standards compliance, and the components of physical environment refurbishments which support resident function.
•First longitudinal study to assess posttraumatic growth and quality of life after burn.•As stress levels increase, self-reported posttraumatic growth (PTG) levels increase.•As mental health ...improves, PTG levels reduce.•Depression is a barrier to posttraumatic growth after burn.•Posttraumatic growth and physical recovery have an inverted-u relationship.
Posttraumatic growth is positive psychological change that occurs beyond pre-trauma levels. Understanding the relationship between growth, stress and quality of life after burn improves understanding about the nature of postburn psychological growth and associated quality of life factors. This study aimed to determine the nature of these relationships, and whether posttraumatic growth changed over time in individuals. Two hundred and seventeen surveys were collected from 73 adult burn patients. The Posttraumatic Growth Inventory, Depression, Anxiety and Stress Score, SF-36 quality of life and Burns Specific Health Score − Brief surveys, together with demographic and clinical information was collected over a six month period. Acute and non-acute burns were equally represented. Growth and stress were positively correlated (p=0.004), but depression and growth had a curved relationship (p=0.050). Growth scores reduced as affect (p=0.008) and mental health improved (p<0.0001), and were highest at mid-levels of physical recovery (p=0.001). This supports the concept that PTG is linked to coping as higher growth is reported with more stress, and that depression is a barrier to growth. As patients recover both physically and mentally from burn, less growth is reported. Early identification and management of depression is important to optimise growth outcomes.

Background:
Platelet-rich plasma (PRP) has been extensively used as a treatment in tissue healing in tendinopathy, muscle injury, and osteoarthritis. However, there is variation in methods of ...extraction, and this produces different types of PRP.
Purpose:
To determine the composition of PRP obtained from 4 commercial separation kits, which would allow assessment of current classification systems used in cross-study comparisons.
Study Design:
Controlled laboratory study.
Methods:
Three normal adults each donated 181 mL of whole blood, some of which served as a control and the remainder of which was processed through 4 PRP separation kits: GPS III (Biomet Biologics), Smart-Prep2 (Harvest Terumo), Magellan (Arteriocyte Medical Systems), and ACP (Device Technologies). The resultant PRP was tested for platelet count, red blood cell count, and white blood cell count, including differential in a commercial pathology laboratory. Glucose and pH measurements were obtained from a blood gas autoanalyzer machine.
Results:
Three kits taking samples from the “buffy coat layer” were found to have greater concentrations of platelets (3-6 times baseline), while 1 kit taking samples from plasma was found to have platelet concentrations of only 1.5 times baseline. The same 3 kits produced an increased concentration of white blood cells (3-6 times baseline); these consisted of neutrophils, leukocytes, and monocytes. This represents high concentrations of platelets and white blood cells. A small drop in pH was thought to relate to the citrate used in the sample preparation. Interestingly, an unexpected increase in glucose concentrations, with 3 to 6 times greater than baseline levels, was found in all samples.
Conclusion:
This study reveals the variation of blood components, including platelets, red blood cells, leukocytes, pH, and glucose in PRP extractions. The high concentrations of cells are important, as the white blood cell count in PRP samples has frequently been ignored, being considered insignificant. The lack of standardization of PRP preparation for clinical use has contributed at least in part to the varying clinical efficacy in PRP use.
Clinical Relevance:
The variation of platelet and other blood component concentrations between commercial PRP kits may affect clinical treatment outcomes. There is a need for standardization of PRP for clinical use.
Background
Venom immunotherapy (VIT) is commonly used for preventing further allergic reactions to insect stings in people who have had a sting reaction. The efficacy and safety of this treatment has ...not previously been assessed by a high‐quality systematic review.
Objectives
To assess the effects of immunotherapy using extracted insect venom for preventing further allergic reactions to insect stings in people who have had an allergic reaction to a sting.
Search methods
We searched the following databases up to February 2012: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, MEDLINE (from 1946), EMBASE (from 1974), PsycINFO (from 1806), AMED (from 1985), LILACS (from 1982), the Armed Forces Pest Management Board Literature Retrieval System, and OpenGrey. There were no language or publication status restrictions to our searches. We searched trials databases, s from recent European and North American allergy meetings, and the references of identified review articles in order to identify further relevant trials.
Selection criteria
Randomised controlled trials of venom immunotherapy using standardised venom extract in insect sting allergy.
Data collection and analysis
Two authors independently undertook study selection, data extraction, and assessment of risk of bias. We identified adverse events from included controlled trials and from a separate analysis of observational studies identified as part of a National Institute for Health and Clinical Excellence Health Technology Assessment.
Main results
We identified 6 randomised controlled trials and 1 quasi‐randomised controlled trial for inclusion in the review; the total number of participants was 392. The trials had some risk of bias because five of the trials did not blind outcome assessors to treatment allocation. The interventions included ant, bee, and wasp immunotherapy in children or adults with previous systemic or large local reactions to a sting, using sublingual (one trial) or subcutaneous (six trials) VIT. We found that VIT is effective for preventing systemic allergic reaction to an insect sting, which was our primary outcome measure. This applies whether the sting occurs accidentally or is given intentionally as part of a trial procedure.
In the trials, 3/113 (2.7%) participants treated with VIT had a subsequent systemic allergic reaction to a sting, compared with 37/93 (39.8%) untreated participants (risk ratio RR 0.10, 95% confidence interval CI 0.03 to 0.28). The efficacy of VIT was similar across studies; we were unable to identify a patient group or mode of treatment with different efficacy, although these analyses were limited by small numbers. We were unable to confirm whether VIT prevents fatal reactions to insect stings, because of the rarity of this outcome.
Venom immunotherapy was also effective for preventing large local reactions to a sting (5 studies; 112 follow‐up stings; RR 0.41, 95% CI 0.24 to 0.69) and for improving quality of life (mean difference MD in favour of VIT 1.21 points on a 7‐point scale, 95% CI 0.75 to 1.67).
We found a significant risk of systemic adverse reaction to VIT treatment: 6 trials reported this outcome, in which 14 of 150 (9.3%) participants treated with VIT and 1 of 135 (0.7%) participants treated with placebo or no treatment suffered a systemic reaction to treatment (RR 8.16, 95% CI 1.53 to 43.46; 2 studies contributed to the effect estimate). Our analysis of 11 observational studies found systemic adverse reactions occurred in 131/921 (14.2%) participants treated with bee venom VIT and 8/289 (2.8%) treated with wasp venom VIT.
Authors' conclusions
We found venom immunotherapy using extracted insect venom to be an effective therapy for preventing further allergic reactions to insect stings, which can improve quality of life. The treatment carries a small but significant risk of systemic adverse reaction.
