RESUMO
BACKGROUND: Chronic low back pain (CLBP) is a significant problem affecting millions of people worldwide. Three widely implemented psychological techniques used for CLBP management are cognitive therapy (CT), mindfulness meditation (MM), and behavioral activation (BA). This study aimed to evaluate the relative immediate (pre- to post-treatment) and longer term (pre-treatment to 3- and 6-month follow-ups) effects of group, videoconference-delivered CT, BA, and MM for CLBP. METHODS: This is a secondary analysis of a three-arm, randomized clinical trial comparing the effects of three active treatments-CT, BA, and MM-with no inert control condition. Participants were N = 302 adults with CLBP, who were randomized to condition. The primary outcome was pain interference, and other secondary outcomes were also examined. The primary study end-point was post-treatment. Intent-to-treat analyses were undertaken for each time point, with the means of the changes in outcomes compared among the three groups using an analysis of variance (ANOVA). Effect sizes and confidence intervals are also reported. RESULTS: Medium-to-large effect size reductions in pain interference were found within BA, CT, and MM (ds from - .71 to - 1.00), with gains maintained at both follow-up time points. Effect sizes were generally small to medium for secondary outcomes for all three conditions (ds from - .20 to - .71). No significant between-group differences in means or changes in outcomes were found at any time point, except for change in sleep disturbance from pre- to post-treatment, improving more in BA than MM (d = - .49). CONCLUSIONS: The findings from this trial, one of the largest telehealth trials of psychological treatments to date, critically determined that group, videoconference-delivered CT, BA, and MM are effective for CLBP and can be implemented in clinical practice to improve treatment access. The pattern of results demonstrated similar improvements across treatments and outcome domains, with effect sizes consistent with those observed in prior research testing in-person delivered and multi-modal psychological pain treatments. Thus, internet treatment delivery represents a tool to scale up access to evidence-based chronic pain treatments and to overcome widespread disparities in healthcare. TRIAL REGISTRATION: Clinicaltrials.gov, NCT03687762.

INTRODUCTION: Physical activity is important to prevent and manage multiple chronic medical conditions. The objective of this study was to describe the implementation of a physical activity vital sign (PAVS) in a primary care setting and examine the association between physical activity with demographic characteristics and chronic disease burden. METHODS: We extracted data from the electronic medical records of patients who had visits from July 2018 through January 2020 in a primary care clinic in which PAVS was implemented as part of the intake process. Data collected included self-reported physical activity, age, sex, body mass index, race, ethnicity, and a modified Charlson Comorbidity Index score indicating chronic disease burden. We classified PAVS into 3 categories of time spent in moderate to strenuous intensity physical activity: consistently inactive (0 min/wk), inconsistently active (<150 min/wk), and consistently active (≥150 min/wk). We used χ2 tests of independence to test for association between PAVS categories and all other variables. RESULTS: During the study period, 13,704 visits, corresponding to 8,741 unique adult patients, had PAVS recorded. Overall, 18.1% of patients reported being consistently inactive, 48.3% inconsistently active, and 33.7% consistently active. All assessed demographic and clinical covariates were associated with PAVS classification (all P < .001). Larger percentages of consistent inactivity were reported for female, older, and underweight or obese patients. Larger percentages of consistent activity were reported for male, younger, and normal weight or overweight patients. CONCLUSION: Using PAVS as a screening tool in primary care enables physicians to understand the physical activity status of their patients and can be useful in identifying inactive patients who may benefit from physical activity counseling.

OBJECTIVES: To evaluate the effect of reinforcing an educational programme through telephone follow-up on health-related quality of life and anxiety and depression symptoms in individuals starting warfarin therapy. BACKGROUND: Educational interventions have improved quality of life in individuals using warfarin. Few studies have examined the addition of telephone follow-up to enhance educational interventions. DESIGN: Randomised controlled trial in outpatient setting. METHODS: Hospitalised adults starting warfarin therapy who agreed to participate received an educational programme about the warfarin treatment. At discharge, they were randomised to receive either five telephone follow-up calls (intervention) or no telephone calls (controls). Both groups were evaluated for health-related quality of life (using Duke Anticoagulation Satisfaction Scale) and symptoms of anxiety and depression (using Hospital Anxiety and Depression Scale) at three and six months post-discharge. Groups were compared at each time by independent-samples t test, and over time by repeated-measures analysis of variance, with time (three and six months), groups (intervention and control) and an interaction between time and group as factors. Level of significance was set at 0.05. The Consolidated Standards of Reporting Trials was used for reporting. RESULTS: Fifty-two individuals (26 per group) completed the study. There were no statistical differences between groups in health-related quality of life, anxiety and depression symptoms, at both times post-discharge. Participants who received follow-up telephone calls reported better positive psychological impact (a subscale of quality of life) than controls. CONCLUSIONS: Reinforcing an educational programme with telephone follow-ups did not have an overall effect on health-related quality of life of individuals using warfarin but promoted positive psychological impact. RELEVANCE TO CLINICAL PRACTICE: The low cost of reinforcing educational programmes with telephone calls and the improvement in positive psychological aspects indicate that this type of intervention is still a promising intervention that could be further investigated and improved.

AIMS AND OBJECTIVES: To compare mentholated popsicle with usual care (absolute fasting) in the change of thirst intensity and discomfort of patients in the preoperative fasting. BACKGROUND: Thirst is defined as the desire to drink water, and it is considered to be a multifactorial symptom. In the preoperative fasting, the patient may experience intense thirst, often for a long time, that can lead to feelings of suffocation, desperation, fear and anxiety. DESIGN: A randomised controlled trial. METHODS: Forty patients, aged between 18-60 years, were randomised to mentholated popsicle group or absolute fasting group (twenty in each). The primary outcomes were thirst intensity, evaluated by a numeric scale ranging from 0 (no thirst)-10 (the worst possible thirst), and discomfort from thirst (evaluated by the Perioperative Thirst Discomfort Scale), both measured twice (baseline and after 20 min of intervention). The CONSORT checklist was used to report this study. RESULTS: Mean age was similar in both groups (38 years in the mentholated popsicle group and 39 in the absolute fasting group). At baseline, the mentholated popsicle group had higher median for the scales of intensity (6.5) and discomfort (7.5) from thirst than the absolute fasting group (5.0 and 5.0, respectively). At the end of 20 min, the popsicle group had a statistically significant decrease in intensity and discomfort from thirst (median decreases of 5.0 and 7.0 points, respectively) when compared to the absolute fasting group (median increases of 0.5 and 1.0 points, respectively). CONCLUSIONS: The use of mentholated popsicle decreased the intensity and discomfort from thirst, and it is a viable strategy for the management of thirst in the preoperative fasting. RELEVANCE TO CLINICAL PRACTICE: In the preoperative fasting, making mentholated popsicles available to patients is an easy strategy to manage thirst, which might lead to better care.

The study assessed if quadriceps femoris muscle performance of older women can be improved by applying photobiomodulation therapy after a resistance training program. This study is a randomized, controlled trial with concealed allocation, intention-to-treat analysis, and blinded outcome evaluators. Forty-five healthy sedentary older women classified as active or insufficiently active were randomized to groups receiving 8 weeks of quadriceps femoris resistance training plus active group or placebo group, or a control group (no training or photobiomodulation). Surface electromyographic fatigue indexes of vastus medialis, rectus femoris, and vastus lateralis; one-maximum repetition (1-MR); and analysis of inflammatory biomarkers (IL-6, IL-8, and TNF-α cytokines, plus CK and LDH enzymes) were measured at baseline and twice in a 24 h-period after 8 weeks. No differences among the three groups were found in fatigue indexes for all three muscles, although in general, the active group presented improved fatigue indexes from baseline to 8-week outcome, while the other groups did not. Both training groups improved in 1-MR over the 8-week period. Inflammatory biomarkers were not different at long- or short-term among the three groups, except differences in groups for long-term IL-8 changes, differences in time for long-term LDH and short-term TNF-α changes, and interactions of time by group for short-term LDH changes. Quadriceps femoris performance of older women was not improved when photobiomodulation was associated to the proposed quadriceps femoris resistance training, when compared to training without photobiomodulation and a sedentary group.

Vieira, KVSG, Ciol, MA, Azevedo, PH, Pinfildi, CE, Renno, ACM, Colantonio, E, and Tucci, HT. Effects of light-emitting diode therapy on the performance of biceps brachii muscle of young healthy males after 8 weeks of strength training: a randomized controlled clinical trial. J Strength Cond Res 33(2): 433-442, 2019-We assessed the effect of adding light-emitting diode therapy (LEDT) to an 8-week strength training of biceps brachii in healthy young males. Forty-five participants were randomized into training plus LEDT, training plus sham LEDT, and control groups (n = 15 each). Individuals in the LEDT groups participated in strength training performed in a Scott machine at their maximum number of elbow flexion-extension repetitions. The LEDT was applied to biceps brachii of dominant limb at the end of training sessions (device "on" for LEDT and "off" for sham LEDT). Training loads were re-evaluated every 2 weeks. Controls did not receive training during 8 weeks. All groups were evaluated for 1 repetition maximum (1RM) and fatigue at baseline and 8 weeks. Additionally, the 2 LEDT groups were evaluated every 2 weeks for 1-RM and number of elbow flexion-extension repetitions. The groups were statistically different in mean difference and mean percent change of 1-RM from baseline to week 8 (p < 0.001). Analyzing the 2 LEDT groups, we found an interaction between group and time (p = 0.02), with a slightly faster increase in 1-RM for the LEDT than the sham LEDT. Over time, both groups decreased the number of repetitions of elbow flexion-extension (differences not statistically significant), possibly because of the increase of load over time. We found no difference in change of fatigue index among the 3 groups. Our study showed potential benefits to 1RM when LEDT is applied after a strength training session. Future studies might assess whether different doses of LEDT can reduce fatigue in strength training.

BACKGROUND: In patients with short-term percutaneous central venous catheter (CVC), it is recommended that a dressing be applied to the catheter insertion site to prevent catheter-related infections. OBJECTIVES: The objective of this study was to assess the feasibility of a randomised controlled trial to compare the efficacy of chlorhexidine-impregnated dressing with that of polyurethane dressing in the prevention of catheter-related infections in critically ill adult patients with short-term percutaneous CVC. METHODS: One hundred fifteen patients with a CVC were randomised to chlorhexidine-impregnated gel dressing (chlorhexidine gel group) or transparent polyurethane dressing (polyurethane group) between April and December 2014. Feasibility outcomes included data on eligibility, recruitment, missing data, and protocol violation. The primary outcome measure of efficacy was the presence of colonisation with the same microorganism in both the skin swab around catheter insertion site and the catheter tip. RESULTS: Of 526 patients assessed for eligibility, 411 (78%) did not meet inclusion criteria, and 115 (22%) were randomised. Among participants of both groups, there were 14 missing primary outcomes of which 10 were due to failure to collect the catheter tip (a protocol violation). The final sample had 47 and 54 individuals in the chlorhexidine and polyurethane groups, respectively. Skin and catheter tip were colonised by the same microorganism for 13% of the participants in the chlorhexidine group and 8% in the polyurethane group, although the difference was not statistically significant (p = 0.51). There were no differences between the two groups for catheter tip colonisation, skin site colonisation, catheter insertion site infection, catheter-related bloodstream infection, skin irritation, and the number of unplanned dressing changes. CONCLUSIONS: Our preliminary results found that a large randomised controlled trial would be feasible. This study provides valuable information that can be used to design more robust studies to prevent infection among patients with short-term percutaneous CVC when using either chlorhexidine or polyurethane dressing.

AIMS: The purposes were to examine construct validity of the Motor Planning Maze Assessment (Maze) and three items from the Functional Gait Assessment (FGA) that were modified for children (pediatric modified FGA, pmFGA), by comparing performance of children with DCD and age matched peers with typical development (TD); the construct validity of total scores of the Dynamic Gait Index (DGI) and the FGA. METHODS: Twenty pairs of children with DCD and TD, age from 5 to 12 years, participated in this study. Children in both groups were tested on the Maze, pmFGA, DGI, and FGA. Paired t-tests and agreement tables were used to compare the motor performances between two groups. RESULTS: The DCD group showed higher summary scores in the Maze (p < 0.001) and demonstrated significantly fewer steps (p ≤ 0.001) while doing the pmFGA items than the TD group. However, the FGA quality scores demonstrated minimal differences between the two groups on all three items. Children with DCD showed significantly lower DGI and FGA total scores (p < 0.001) than the TD group. CONCLUSION: The Maze, DGI, and FGA tests are easily applied in clinical settings and can differentiate motor planning and gait coordination between children with DCD and with TD.

PURPOSE: The aim of this study is to compare cryotherapy made only with water and cryotherapy made with chamomile infusion for prevention and reduction of intensity of oral mucositis in patients with cancer receiving 5-fluorouracil and leucovorin. METHOD: This is a randomized pilot study with two groups: cryotherapy made only with water (control group, n = 18) and cryotherapy made with chamomile infusion (chamomile group, n = 20). Both groups were instructed to swish the ice around in their oral cavity for at least 30 min during chemotherapy. Assessment of oral mucosa occurred on days 8, 15, and 22 after the first day of chemotherapy. RESULTS: Fifty percent of the patients in the control and 30 % in the chamomile group developed oral mucositis. Mouth pain score was higher in patients in the control group on all evaluations (p = 0.02 for day 8, p = 0.09 for day 15, and p = 0.14 for day 22). Patients in the chamomile group never developed mucositis with grade 2 or higher. Presence of ulceration was statistically significant on day 8 (16 % in the control vs. 0 % in the chamomile group, p = 0.10), but not in days 15 and 22, although 11 % still had ulcerations in the control group and none in the chamomile group. CONCLUSION: The occurrence of oral mucositis was lower in patients in the chamomile group than in the control group. When compared to the controls, the chamomile group presented less mouth pain and had no ulcerations. Cryotherapy was well tolerated by both groups, and no toxicity related to chamomile was identified.

AIM: To compare a gel made with chamomile (Chamomilla recutita) with a cream of urea as an intervention to delay the time to occurrence of radiation dermatitis. BACKGROUND: Radiation dermatitis is one of the most common adverse effects of radiotherapy in patients with head and neck cancer. It is characterized by erythema, itching, pain, skin breakage and burning sensation, and there is no consensus on how to prevent it. DESIGN: The study is a randomized controlled clinical trial. METHODS: We will recruit 48 individuals with head and neck cancer who will be starting their radiotherapy and randomize them to receive either gel of chamomile or cream of urea, as an intervention for prevention of radiation dermatitis. Social-demographic data will be collected at baseline, and clinical data will be collected before the initiation of radiotherapy. Participants will be followed weekly to assess development of radiation dermatitis. The protocol is funded by Conselho Nacional de Pesquisa e Desenvolvimento Científico (Brazil). The study was approved by a research ethics committee. DISCUSSION: Given the clinical relevance of preventing radiation dermatitis and the lack of evidence supporting specific preventive interventions, it is important to study new products that might be efficacious to prevent this complication. This article presents the protocol of a randomized controlled trial comparing a gel made with chamomile (intervention) with a cream of urea (control) to prevent radiation dermatitis in patients with head and neck cancer undergoing radiotherapy.

PURPOSE: To examine the effects of Sensorimotor Training to Affect Balance, Engagement, and Learning (STABEL), a virtual reality system to train sensory adaptation for balance control, for children with fetal alcohol spectrum disorders (FASDs). METHODS: Twenty-three children with FASDs received STABEL training in a university laboratory, or home, or were controls. The Movement Assessment Battery for Children-2nd edition (MABC-2) and Pediatric Clinical Test of Sensory Interaction for Balance-2 (P-CTSIB-2) were analyzed by group (lab, home, and control), session (pre-STABEL, 1 week post-STABEL, and 1 month post-STABEL), and group-by-session interaction. RESULTS: Significant effects were group and session for MABC-2 Balance and interaction for MABC-2 Total Motor and P-CTSIB-2. CONCLUSION: Preliminary results support improved sensory adaptation, balance, and motor performance post-STABEL, which warrant further study with a larger, randomized sample.

PURPOSE/BACKGROUND: Multiscale entropy (MSE) is a nonlinear measure of postural control that quantifies how complex the postural sway is by assigning a complexity index to the center of pressure (COP) oscillations. While complexity has been shown to be task dependent, the relationship between sway complexity and level of task challenge is currently unclear. This study tested whether MSE can detect short-term changes in postural control in response to increased standing balance task difficulty in healthy young adults and compared this response to that of a traditional measure of postural steadiness, root mean square of velocity (VRMS). METHODS: COP data from 20 s of quiet stance were analyzed when 30 healthy young adults stood on the following surfaces: on floor and foam with eyes open and closed and on the compliant side of a Both Sides Up (BOSU) ball with eyes open. Complexity index (CompI) was derived from MSE curves. RESULTS: Repeated measures analysis of variance across standing conditions showed a statistically significant effect of condition (p < 0.001) in both the anterior-posterior and medio-lateral directions for both CompI and VRMS. In the medio-lateral direction there was a gradual increase in CompI and VRMS with increased standing challenge. In the anterior-posterior direction, VRMS showed a gradual increase whereas CompI showed significant differences between the BOSU and all other conditions. CompI was moderately and significantly correlated with VRMS. CONCLUSIONS: Both nonlinear and traditional measures of postural control were sensitive to the task and increased with increasing difficulty of standing balance tasks in healthy young adults.

AIMS: To test an educational programme with telephone follow-up to improve self-care in Brazilian patients who underwent percutaneous coronary intervention. BACKGROUND: Percutaneous coronary intervention has been established as a treatment for coronary disease. However, additional intervention is needed to improve self-care for individuals who undergo this procedure to reduce further disease. Telephone follow-up is one strategy that has been used to improve chronic disease self-care. DESIGN: Randomized controlled trial. TRIAL REGISTRATION: ClinicalTrials.gov, NCT01341093. METHODS: Sixty patients who were preparing for their first percutaneous coronary intervention between 2011-2012 were randomly allocated to an educational programme with telephone follow-up (N = 30) or a control group (N = 30). Perceived health status was assessed with the Medical Outcomes Study 36-Item Short Form. Self-efficacy, symptoms of anxiety and depression and medication adherence were also assessed. Measures were collected before intervention (baseline) and 6 months later. RESULTS: Both groups improved from baseline to 6 months in the 'Physical Component Summary' and in the domains of 'Physical Functioning', 'Role-Emotional' and 'Role-Physical'. The educational programme group showed a reduction in anxiety from baseline to 6-month follow-up, while the control group showed a slight increase. No differences in symptoms in depression and self-efficacy were found and both groups reported high levels of medication adherence. CONCLUSION: The educational programme with telephone follow-up is a promising intervention as it led to reduction in anxiety for those receiving the educational programme. Further improvements in timing and focus of the educational programme, such as targeting emotional and social lifestyle changes, might be warranted.

What happens at the sensory level when a person is balancing on compliant surfaces? Compliant surfaces such as both-sides-up (BOSU) balls are often used as a form of "proprioceptive exercises." Clinical theories in neurorehabilitation suggest that compliant surfaces disrupt the somatosensory contribution to balance and increase reliance on vision and vestibular input. Understanding the sensory aspects of compliant surfaces' exercises would have important implications for balance training of athletes and of people with somatosensory deficits such as people with recurrent ankle sprains. We tested this clinical theory in a sample of 30 healthy young adults and 10 adults with a history of repeated ankle sprains while they were standing on a BOSU ball, memory foam, or floor. We measured participants' center of pressure response to dots projected on a screen, moving mediolaterally at one of the 3 frequencies (0.4, 0.48, and 0.56 Hz). We calculated magnitude of the postural response (gains) and participants' primary frequency (PF) of sway and compared it between surfaces per frequency. In both groups, gains were significantly higher on the BOSU compared with floor or foam (p < 0.001) with no significant difference between floor and foam. The PF difference was significant (p < 0.001) with a clear peak matching of the visual stimulation frequency only on the BOSU. During a single session of stance on compliant surfaces, visual dependence was a dominant factor on a challenging condition. When prescribing BOSU exercises to young adults as specific balance training, trainers should consider its effect on increased visual dependence with respect to that session's goals.

OBJECTIVE: To evaluate the effect of a physical activity intervention upon the incidence of gallbladder sludge or stones during pregnancy. STUDY DESIGN: Pregnant women without gallstones were randomized to an intervention to increase moderate to vigorous physical activity or control. Intervention group women received motivational materials and small-group instruction to increase physical activity. Gallbladder ultrasound and blood draws were obtained at entry, 18 weeks' gestation, and 36 weeks' gestation. RESULTS: In all, 591 were randomized to the intervention and 605 women to control groups. Women in the intervention group reported modestly higher levels of physical activity compared with control women, and fewer women in the intervention group reported no physical activity during pregnancy. The incidence of gallbladder sludge or stones was similar in intervention and control groups at 18 weeks (4.8% versus 5.4%; relative risk 0.89; 95% confidence interval 0.53, 1.47) and 36 weeks (4.3% versus 3.3%; relative risk 1.31; 95% confidence interval 0.70, 2.54). Fasting glucose, lipid, insulin, leptin, and adiponectin levels were similar in the two groups, as was insulin sensitivity and the incidence of gestational diabetes. CONCLUSION: An intervention to increase moderate to vigorous physical activity did not decrease the incidence of gallbladder sludge or stones during pregnancy and did not result in improvement in maternal metabolic measures.

True vocal fold (TVF) dysfunction may lead to cough ineffectiveness. In individuals with motor neuron disease (MND), cough impairment in the context of dysphagia increases risk for aspiration and respiratory failure. This study characterizes differences and associations between TVF kinematics and airflow during cough in individuals with bulbar MND. Sequential glottal angles associated with TVF movements during volitional cough were analyzed from laryngeal video endoscopy examinations of adults with bulbar MND (n = 12) and healthy controls (n = 12) and compared with simultaneously collected cough-related airflow measures. Significant group differences were observed with airflow and TVF measures: volume acceleration (p ≤ 0.001) and post-compression abduction TVF angle average velocity (p = 0.002) were lower and expiratory phase rise time (p = 0.001) was higher in the MND group. Reductions in maximum TVF angle during post-compression abduction in the MND group approached significance (p = 0.09). All subjects demonstrated complete TVF and supraglottic closure during the compression phase of cough, except for incomplete supraglottic closure in 2/12 MND participants. A strong positive relationship between post-compression maximum TVF abduction angle and peak expiratory cough flow was observed in the MND group, though it was not statistically significant (r = 0.55; p = 0.098). Reductions in the speed and extent of TVF abduction are seen during the expulsion phase of cough in individuals with MND. This may contribute to cough impairment and morbidity.

AIM AND OBJECTIVES: To assess the construct validity and reliability of the Brazilian Portuguese versions of the 29- and 13-item scales of the Antonovsky's Sense of Coherence Scale (SOC-29 and SOC-13). BACKGROUND: Antonovsky's Sense of Coherence Questionnaire was developed to measure the main construct of the salutogenic theory, the sense of coherence. The use of the sense of coherence by health professionals might help identifying specific coping strategies used by person with chronic illness. DESIGN: Cross-sectional study. METHODS: The SOC-29 has been culturally adapted to Brazilian Portuguese language. In this study, we assessed its psychometric properties (construct validity and internal reliability) tested on 203 cardiac patients. The SOC-13 was tested on another 100 cardiac patients hospitalised in the same hospital. The construct validity of both versions was investigated through Pearson correlation between the measures of sense of coherence and of correlated constructs (self-esteem, depression and age), analysis of the principal components and comparison of distinct groups (male vs. female). The internal reliability for both versions was evaluated by Cronbach's alpha. RESULTS: For both versions, the construct validity assessments showed strong positive correlations between sense of coherence and self-esteem and strong negative correlations between sense of coherence and depression (convergent validity), and weak correlation between sense of coherence and age (divergent validity). Principal component analysis supported in part the presence of a single component (unidimensionality). Differences in sense of coherence were found by sex with SOC-29, but not with SOC-13. Cronbach's alpha coefficients showed satisfactory internal consistency in both versions. CONCLUSIONS: The Brazilian Portuguese versions of SOC-29 and SOC-13 can be considered valid and reliable for the populations studied. More studies need to be performed to assess these proprieties in other Brazilian populations. RELEVANCE TO CLINICAL PRACTICE: This scale can be used in research and clinical practice in Brazil to assess nursing interventions aimed at decreasing stress during cardiac rehabilitation.

BACKGROUND: During the COVID-19 pandemic, there was a shortage of filtering facepiece respirators (FFR), leading to prolonged use and reuse of FFRs. METHODS: FFRs were collected in 3 hospitals after extended use (up to 15 or 30days). We assessed the physical characteristics and filtration levels of worn FFRs, before sterilization. Respirators that achieved at least 94% filtration of aerosol particles, nasal clip still attached, had no tears, had preserved elastic bands, and had no dirt were randomized to receive or not receive cleaning before being submitted to hydrogen peroxide plasma gas sterilization. RESULTS: A total of 1,055 FFRs were collected. Over 85% of them exhibited secured nose clips, preserved strap elasticity, and no tears. However, more than 78% of samples contained dirt, leaving only 101 (19.6%) eligible to undergo sterilization. After sterilization, none of the FFRs in either group achieved minimum filtration, although 72% without cleaning and 80% with cleaning had filtration between 90.0% and 93.9%. DISCUSSION: A large proportion of FFRs were ineligible for sterilization due to factors unrelated to health care (eg, dirt from makeup). CONCLUSIONS: Prolonged reuse of FFRs significantly reduced aerosol filtration efficiency. Eligible FFRs did not maintain 94% filtration after sterilization with or without cleaning.
RESUMO
BACKGROUND AND PURPOSE: Head and neck cancer patients frequently develop radiation dermatitis (RD) during radiotherapy. We compared liposomal gel with and without chamomile extract for the prevention and management of RD in head and neck cancer patients undergoing radiotherapy. MATERIALS AND METHODS: Sixty participants undergoing radiotherapy for the first time for head and neck cancer were recruited in a double-blind randomized clinical trial. Primary outcomes were the occurrence of dry desquamation and the cumulative dose of ionizing radiation at the first occurrence of dry desquamation. Secondary outcomes were the occurrence of erythema, moist desquamation, global RD, and participant self-reported symptoms. RESULTS: Dry desquamation occurred in 76.9 % (95 % CI: 57.9, 89.0) of participants in the chamomile liposomal gel group and in 88.9 % (95 % CI: 71.9, 96.1) in the liposomal gel group (p = 0.43). The median cumulative dose of ionizing radiation when dry desquamation occurred was 48.0 Gy in the chamomile liposomal gel group and 40.0 Gy in the liposomal gel group. Fewer symptoms were reported in the chamomile liposomal gel group. CONCLUSION: No statistically significant differences in outcomes were found between the two groups, though the chamomile liposomal gel group presented with lower grades of RD than the liposomal gel group. In addition, when compared to the literature on other topical interventions to manage RD, our results show that chamomile liposomal gel has potential for better management and prevention of RD in this population, which should be further tested. This study provides crucial information to design future studies. Clinical Trials Registration (REBEC): RBR-92cts3.
RESUMO
OBJECTIVE: The current study examined the associations between catastrophizing and pain intensity, psychological adjustment, functional ability, and community participation in youths with physical disability and chronic pain. METHODS: Participants consisted of 80 youths, aged 8-20 years, with cerebral palsy (n = 34), neuromuscular disease (n = 22), or spina bifida (n = 24). Measures from a cross-sectional survey included demographic, pain, and disability information, the Pain Catastrophizing Scale, the Child Health Questionnaire, and the Functional Disability Inventory. RESULTS: Results suggested that catastrophizing was significantly associated with pain intensity and psychological adjustment; however, catastrophizing did not demonstrate significant associations with functional ability or community participation. CONCLUSIONS: The study extends previous findings of significant associations between catastrophizing and both pain intensity and psychological adjustment to samples of youths with chronic pain and disabilities not previously examined. Further research that examines the causal association between catastrophizing and outcomes in youths with chronic pain and physical disability is warranted.
