Visual analogue scale (VAS) as a monitoring tool for daily changes in asthma symptoms in adolescents: a prospective study

The First Step is the Hardest: A Mixed Methods Single-Case Experimental Design Study of a VR-Enhanced Training Program in a Forensic Youth Care Setting

Street Temptations is a virtual reality-enhanced training program developed as an add-on intervention for adolescents with disruptive behavior problems. Using mentalization as a primary treatment mechanism, the program aims to address cognitive distortions and increase motivation for behavior change. This study provides an initial evaluation of Street Temptations in a forensic youth care setting, utilizing both quantitative and qualitative data within an A-B-A' single-case experimental design. Throughout a baseline, intervention, and follow-up phase, adolescents completed daily measurements on cognitive distortions and motivation for behavior change. Secondary outcomes were assessed before baseline, after intervention, and after follow-up, which included mentalization and perspective-taking. Qualitative data were collected after the intervention through separate interviews with adolescents and Street Temptations therapists. A total of 8 adolescents were included in the study, 5 of whom dropped out, leaving 3 who provided sufficient data for visual inspection of the outcomes. The observed patterns suggested an increase in adolescents' awareness of others' perspectives during participation in Street Temptations, potentially indicating a positive effect on cognitive distortions. However, daily assessments did not show an increase in adolescents' motivation for behavior change. Positive effects of Street Temptations and virtual reality, as well as areas for improvement, were highlighted in all interviews. Recommendations for further development and implementation are discussed. Overall, this study provides preliminary support for the use of Street Temptations as an add-on intervention in forensic youth care.

The Canadian Lung Outcomes in Users of Vaping Devices (CLOUD) Study: protocol for a prospective, observational cohort study

INTRODUCTION

The rapid growth in popularity of e-cigarettes over the past decade has prompted concerns about their impact on long-term respiratory health. Small airway injury is suspected to be a direct consequence of e-cigarette use and may be quantifiable by novel structural and functional diagnostic modalities.

METHODS AND ANALYSIS

In a multicentre observational longitudinal study, participants will be enrolled in either an adolescent (ages ≥12 and <19 years) or an adult arm (≥19 years old) and followed over 3 years across three time points (baseline, 18 months and 36 months). In the adolescent arm, a total of 50 e-cigarette and 50 non-e-cigarette users will be enrolled across 4 sites. In the adult arm, a total of 100 e-cigarette users, 100 non-e-cigarette users, and an additional 100 combustible cigarette-only users and 100 dual combustible cigarette-e-cigarette users will be enrolled across 5 sites. Participants will undergo respiratory questionnaires, pulmonary function tests, oscillometry, cardiopulmonary exercise testing, hyperpolarised 129-xenon gas MRI and blood collection. In adolescent participants only, multiple breath washout and induced sputum collection will be performed. Adult participants will also undergo inspiratory/expiratory chest CT and bronchoscopy. The primary endpoint will be a composite of small airway dysfunction according to oscillometry, cardiopulmonary testing and/or chest imaging parameters.

ETHICS AND DISSEMINATION

This protocol has been approved by The University of British Columbia-Providence Health Care Research Ethics Board (Certificate H24-00374). The use of hyperpolarised 129-xenon gas in this study has been approved by Health Canada (Certificate HC6-024-c291776). Written documentation of informed consent will be required prior to study initiation. We will seek to enrol adolescent participants who are capable of providing informed consent with an optional support statement from a parent encouraged but not required. Study findings will be disseminated to medical/scientific audiences through scientific conferences and published manuscripts respecting the Strengthening the Reporting of Observational Studies in Epidemiology statement, to youths through outreach events at high schools and community programmes and through social media, and to adults through lung health community events.

Effect of Dietary Supplementation with Lutein, Zeaxanthin, and Elderberries on Dry Eye Disease (DED) and Immunity: A Randomized Controlled Trial

BACKGROUND/OBJECTIVES

Dry eye disease (DED) significantly impairs quality of life, affecting physical, social, and psychological well-being, as well as reducing workplace productivity. While lutein and zeaxanthin supplements have been shown to improve ocular health, existing research often overlooks the efficacy of lower dosages and shorter durations of supplementation. This study investigated the effects of combined supplementation with lutein, zeaxanthin, and elderberries in 110 voluntary participants through a randomized controlled trial.

METHODS

Participants took 6 mg of lutein and 1 mg of zeaxanthin, along with 100 mg elderberry extract once daily for a duration of 20 days. Ocular health was assessed using the Ocular Surface Disease Index (OSDI), while immune status was evaluated with the Immune Status Questionnaire (ISQ).

RESULTS

Results showed that combined supplementation significantly (p < 0.05) reduced the OSDI scores in the intervention group from 38.15 ± 11.14 to 18.26 ± 5.57, reflecting a 52.2% reduction. A similar trend was observed with the Visual Analog Scale (VAS), indicating significant (p < 0.05) improvement from 5.31 ± 1.62 to 6.73 ± 1.74, equivalent to a 26.7% improvement. Although the intervention group showed a 15.9% improvement in ISQ scores by the study's end, this was not significantly different from the placebo group, suggesting that higher dosages or longer durations may be needed to observe a meaningful effect. Additionally, findings from the Food Frequency Questionnaire revealed that the average dietary intake of lutein and zeaxanthin among participants was only 663.49 µg, equating to just 5.5% of the suggested optimal daily intake. This low consumption is concerning, as it is inversely correlated with the risk of ocular diseases.

CONCLUSIONS

Collectively, these findings support the use of combined supplementation as an adjuvant approach to improving ocular health.

Efficacy and perceived satisfaction of 3-year SLIT in children with allergic rhinitis and asthma: a pilot study

BACKGROUND

Despite the presence of robust evidence, there is very limited data on the efficacy of allergen immunotherapy (AIT) for selected patients. Accordingly, we aimed to evaluate the efficacy and perceived satisfaction of a 3-year course of sublingual immunotherapy (SLIT) in a paediatric population with allergic rhinitis and/or asthma.

METHODS

A pilot, monocentre, retrospective cohort study was performed. One hundred fifty-three children who fulfilled the criteria for allergic rhinitis and asthma and were either mono- or poly-sensitized were enrolled. A standardized questionnaire assessing perceived efficacy, use of rescue medication, disease control, number of exacerbations, quality of life, and perceived satisfaction was administered to each patient.

RESULTS

Seventy patients (49 males, 21 females; mean age, 14.3±1.9 years) were included in the final analysis. All 70 patients received SLIT for up to 3 years, with 100% adherence to the treatment throughout the study. Significant improvements in symptoms and quality of life were reported (p<0.01). There was also a significant decrease in disease severity, use of rescue medication, and sleep disturbances (p<0.01). Additionally, a significant improvement in school performance was also recorded (p<0.01). Of the enrolled patients, 60 out of 70 (85.7%) reported being very satisfied, 6 out of 70 (8.57%) were much satisfied, and 4 out of 60 (5.71%) were satisfied.

CONCLUSIONS

We were the first to demonstrate the efficacy and perceived satisfaction of a 3-year SLIT in a paediatric population, with 100% treatment adherence throughout the study.

Rhinoconjunctivitis severity induced by cat exposure influences early and late asthmatic responses: Evidence from an environmental exposure chamber

BACKGROUND

The impact of allergic rhinoconjunctivitis on the early (EAR) and late asthmatic response (LAR) has yet to be assessed during optimal allergen exposure conditions.

OBJECTIVE

We aimed to assess predictive factors of the EAR and LAR and to evaluate the relation between rhinitis, conjunctivitis and asthma induced by cat allergen exposure in an environmental exposure chamber (EEC).

METHODS

Data from two cohort studies involving asthmatic patients with cat allergy who performed a cat allergen exposure challenge in ALYATEC EEC were analysed. Spirometry, visual analogue scale (VAS) for asthma, VAS for rhinitis, Total Nasal Symptoms Score, Total Ocular Symptoms Score (TOSS), Rhinoconjunctivitis Total Symptoms Score and Abelson score were used to assess asthma, rhinitis and conjunctivitis during and after exposure.

RESULTS

An EAR occurred in 65.1% of patients, 32.1% of whom had a LAR. The diameter of the prick test to cat allergens and non-specific bronchial hypersensitivity level were independent risk factors for EAR (p < .05). No independent risk factors for LAR were identified. Rhinoconjunctivitis severity during exposure correlated with the asthma VAS during EAR and LAR (p < .05). Allergen exposure time needed to trigger an EAR correlated with the Abelson score during exposure (p < .05). The asthma VAS and TOSS during exposure correlated with faster LAR occurrence (p < .05).

CONCLUSION

Prick test size and non-specific bronchial hypersensitivity level were confirmed as independent predictive factors of EAR during allergen exposure in an EEC. This study demonstrated the relation between the severity of rhinitis, conjunctivitis and asthma induced by allergen exposure for both EAR and LAR.

The Analgesic Effects of the Thoracic Paravertebral Block on Post-percutaneous Nephrolithotripsy: A Retrospective Study

INTRODUCTION

Percutaneous nephrolithotripsy (PCNL) is a minimally invasive procedure for treating large and complex kidney stones, often resulting in significant post-operative pain and increased opioid use. This study aims to compare pain scores between patients undergoing PCNL who did and did not receive a preoperative single-shot thoracic paravertebral block (PVB) at the post-anesthesia care unit (PACU) as the primary outcome. Secondary outcomes were patient-controlled analgesia (PCA) usage on post-operative day 1 (POD 1), total opioid consumption on PACU and POD 1, and post-operative nausea and vomiting (PONV).

METHODS

A retrospective cohort study was conducted on the medical records of 341 patients who underwent PCNL from July 2014 to April 2016 in a single major academic center. PVB was administered at thoracic levels T7-9 using a volume of 20 cc of bupivacaine, ranging from 0.25% to 0.5%, to achieve the desired analgesic effect.

RESULTS

After excluding 34 patients, the study included 123 in the no block (NB) group and 149 in the regional anesthesia (RA) group. There were no differences in demographics, including age, sex, weight and height, BMI, and indication for PCNL. The results revealed that the RA group experienced a statistically significant reduction in PCA usage in both crude and adjusted models (adjusted logistic regression analysis: OR = 0.19, 95% CI = 0.05-0.60; p = 0.008). However, there were no significant changes in total opioid consumption, pain scores, or incidents of PONV.

CONCLUSION

The retrospective analysis did not reveal any discernible advantage in pain management associated with the use of PVB for post-PCNL analgesia, except for reducing the percentage of PCA narcotics used. Future investigations with larger sample sizes and meticulous control for surgical indications and complexity are imperative to accurately assess the efficacy of this block in the context of post-PCNL surgery.

Eosinophilic Patterns in Patients with Seasonal Allergy Affected by Bronchial Asthma and Rhinitis/Rhinosinusitis: Efficacy of Benralizumab in Patients with the Persistent Pattern

BACKGROUND

Eosinophilia can be influenced by multiple factors. This study aims to set a protocol for monitoring blood absolute eosinophil count (AEC) in patients with seasonal allergy affected by bronchial asthma (BA), allergic rhinitis (AR), or chronic rhinosinusitis with or without nasal polyposis (CRSw/sNP).

METHODS

We planned a total of four annual blood samples to measure AEC in- and out-seasonal pollen exposure (i.e., one measurement every three months for one year).

RESULTS

We identified two distinct groups of patients (non-eosinophilic and eosinophilic). Patients in the eosinophilic group presented with four different patterns (episodic, transient, floating, and persistent). Most patients with episodic, transient, and floating patterns were affected by mild allergy and the increase in eosinophils was related to allergen exposure. In contrast, patients with the persistent pattern mostly presented with more severe allergy (i.e., severe BA and relapsing CRSwNP) and the eosinophilia was unrelated to allergen exposure. The subgroup of patients with severe BA, relapsing CRSwNP, and persistent eosinophilc pattern were treated with benralizumab, which induced a noteworthy improvement in both severe BA and CRSwNP.

CONCLUSIONS

Multiple AEC measurements in patients with seasonal allergy can better reflect patient's eosinophilic status and help define the relationship of AEC enhancement with allergen exposure.

A systematic review of questionnaires measuring asthma control in children in a primary care population

Several questionnaires are used to measure asthma control in children. The most appropriate tool for use in primary care is not defined. In this systematic review, we evaluated questionnaires used to measure asthma control in children in primary care and determined their usefulness in asthma management. Searches were performed in the MEDLINE, Embase, Web of Science, Google Scholar and Cochrane databases with end date 24 June 2022. The study population comprised children aged 5-18 years with asthma. Three reviewers independently screened studies and extracted data. The methodological quality of the studies was assessed, using the COSMIN criteria for the measurement properties of health status questionnaires. Studies conducted in primary care were included if a minimum of two questionnaires were compared. Studies in secondary or tertiary care and studies of quality-of-life questionnaires were excluded. Heterogeneity precluded meta-analysis. Five publications were included: four observational studies and one sub-study of a randomized controlled trial. A total of 806 children were included (aged 5-18 years). We evaluated the Asthma Control Test (ACT), childhood Asthma Control Test (c-ACT), Asthma APGAR system, NAEPP criteria and Royal College of Physicians' '3 questions' (RCP3Q). These questionnaires assess different symptoms and domains. The quality of most of the studies was rated 'intermediate' or 'poor'. The majority of the evaluated questionnaires do not show substantial agreement with one another, which makes a comparison challenging. Based on the current review, we suggest that the Asthma APGAR system seems promising as a questionnaire for determining asthma control in children in primary care.

The prevalence of medical adhesive-related skin injury caused by protective dressings among medical staff members during the 2019 coronavirus pandemic in China

AIM

To explore the prevalence and risk factors for medical adhesive-related skin injury (MARSI) caused by protective dressings among medical staff members during the 2019 coronavirus disease pandemic (COVID-19) in China.

MATERIALS AND METHODS

A cross-sectional survey was conducted using a questionnaire. The questionnaire was released through the Questionnaire Star website and was completed online. The prevalence of MARSI was calculated and risk factors were analyzed using a multiple regression model.

RESULTS

A total of 414 front-line medical staff members treating COVID-19 patients were enrolled from 46 hospitals across four provinces and two municipalities. Overall, 83.1% used protective medical adhesive dressings applied to the head and face to prevent skin damage from personal protective equipment. The prevalence of MARSI caused by adhesive dressings was 41.9%. By multiple regression analysis, the type of dressing, duration of dressing usage, and pain score were risk factors for MARSI development.

CONCLUSIONS

The high prevalence indicates MARSI is common among front-line medical staff members, especially those using hydrocolloid dressings and longer durations of dressing usage. Pain upon dressing removal can be severe and increased the risk of MARSI. We call for paying more attention to MARSI and recommend multisite studies with larger sample sizes to enhance the generalizability of these findings.

Daytime and Nighttime Visual Analog Scales May Be Useful in Assessing Asthma Control Levels Before and After Treatment

PURPOSE

Few questionnaires evaluate daytime and nighttime symptoms separately, although these assessments could contribute to the improvement of disease control levels and prevention of future risks in asthma. The purpose of this retrospective study was to investigate whether daytime and nighttime visual analog scales (VAS) are useful in measuring the perception of symptoms, assessing disease control levels, and evaluating the treatment effects in asthma.

PATIENTS AND METHODS

Self-reporting asthma control tests (ACT) before and after treatment are standardized tests used to determine disease control levels. A multiple regression analysis was performed to determine the correlation between daytime and nighttime VAS and the characteristics of patients before treatment, as well as the changes in VAS and lung functions and fractional exhaled nitrogen oxide after treatment in 55 treatment-naïve symptomatic adult patients with asthma.

RESULTS

Both daytime (r = -0.57, P < 0.0001) and nighttime (r = -0.46, P < 0.0001) VAS correlated well with ACT scores, and there was a correlation between daytime and nighttime VAS (r = 0.33, P = 0.0148) before treatment. In addition, the changes in daytime (r = -0.65, P < 0.0001) and nighttime (r = -0.44, P < 0.0001) VAS were significantly associated with changes in the ACT scores. The multiple regression analysis (β [95% confidence interval]) revealed that improvements in the daytime (-2.33 [-4.55 to -0.11], P = 0.0405) and nighttime (-3.09 [-6.25 to 0.07], P = 0.0505) VAS were associated with an increased forced vital capacity after treatment, although there was no correlation between the VAS and characteristics before treatment.

CONCLUSION

Our study demonstrated that daytime and nighttime VAS were useful in assessing disease control levels and evaluating the treatment effects in asthma.

Total Wrist Arthroplasty-A Systematic Review of the Outcome, and an Introduction of FreeMove-An Approach to Improve TWA

The Swanson silicone prosthesis was one of the first devices to realize total wrist arthroplasty (TWA). It has been used regularly since the early 1960s. This systematic review of the literature evaluated the status quos of TWA. The present study was conducted according to the PRISMA guidelines. A literature search was made in Medline, PubMed, Google Scholar, and the Cochrane Library databases. The focus of the present study was on implant survivorship and related functional outcomes. Data from 2286 TWA (53 studies) were collected. Fifteen studies were included for the analysis of implant survivorship. Fifteen studies were included for the analysis of pain. Twenty-eight studies were included for the analysis of the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Grip strength was tracked in 16 studies. The range of motion (RoM) was evaluated in 46 studies. For supination and pronation, 18 articles were available. Despite some methodological heterogeneities, TWA may be effective and safe in pain reduction and improving function and motion. There is still a range for a future improvement of the procedure.

The use of online visual analogue scales in idiopathic pulmonary fibrosis

Idiopathic pulmonary fibrosis (IPF) is a progressive, deadly disease with a major impact on the lives of patients [1]. Symptom burden and quality of life (QoL) can be assessed with patient-reported outcome measures (PROMs). In the past decade, PROM use was increasingly advocated to capture the impact of treatments and interventions on patients’ symptoms and wellbeing [2]. PROMs are often lengthy, on paper, and with difficult scoring systems, hampering direct use in clinical practice [2]. Thus, there is a need for easy-to-use PROMs in IPF and other interstitial lung diseases (ILDs), both for clinical trials and daily practice.

The visual analogue scale is a valid and reliable tool to assess symptoms over time in IPF. Because of their simplicity, visual analogue scales have the potential to be used for systematic evaluation of disease course in trials and daily practice.https://bit.ly/3BuxJsf

Allergic rhinitis and asthma symptoms in a real-life study of MP-AzeFlu to treat multimorbid allergic rhinitis and asthma

Background

Asthma affects up to nearly 40% of patients with allergic rhinitis (AR). Poor control of AR symptoms is associated with poor asthma control. The goal of this study was to evaluate the effect of AR treatment with MP-AzeFlu on symptoms of AR as well as symptoms of asthma.

Methods

This prospective study used a visual analog scale (VAS) to assess symptoms of AR and asthma before and after treatment with MP-AzeFlu (Dymista^®; azelastine hydrochloride plus fluticasone propionate; 1 spray in each nostril twice daily for 2 weeks). Participants suffered from moderate-to-severe AR according to Allergic Rhinitis and its Impact on Asthma criteria, with acute AR symptoms (AR-VAS scores ≥ 50 mm) on inclusion day. In addition to symptom assessment, patients recorded the impact of AR symptoms on quality-of-life measures before, during, and at the conclusion of the treatment period (approximately 14 days). Patients self-reported change in frequency of their usage of asthma reliever medication on the last day of treatment.

Results

Of 1103 study participants, 267 (24.2%) had comorbid asthma. These participants reported using a mean of 5.1 puffs of asthma reliever medication in the week before treatment with MP-AzeFlu. A total of 81.8% of patients with comorbid asthma responded to AR therapy (AR-VAS < 50 mm on at least 1 study day). Among patients with AR and comorbid asthma, MP-AzeFlu was associated with improved VAS scores across all study parameters, including AR symptom severity, asthma symptom severity, sleep quality, daily work or school activities, daily social activities, and daily outdoor activities. Asthma symptom severity decreased from a mean of 48.9 mm to 24.1 mm on the VAS. Self-reported frequency of asthma reliever medication use was reduced for 57.6% of participants (n = 139/241).

Conclusion

MP-AzeFlu used to relieve AR symptoms was associated with reduced asthma symptom VAS scores and frequency of asthma reliever medication usage. Changes in overall symptoms of AR and asthma were correlated.

Psychometric properties of a single-item visual analog scale measuring goals of care in patients with advanced cancer

PURPOSE

The purpose of this study was to examine the psychometric properties of a single-item visual analog scale (VAS) to measure goals of care in patients with advanced cancer.

METHODS

Data were obtained from 378 patients with diagnoses of advanced lung, gastrointestinal, or pancreatic cancer. Goal of care was measured at baseline and every 3 months until patient death or completion of the 15-month study period. A single-item VAS ranging from 0 (quality of life is all that matters) to 100 (length of life is all that matters) was used to measure patients' goals of care for all study subjects; a subsample of subjects also completed the Quality of Life-Length of Life scale which asked patients to select categories of preferences. Test-retest reliability (intra-class correlation) and construct validity (known-groups, convergent, divergent) were evaluated.

RESULTS

At 9 and 12 months, the test-retest reliability for patients with stable symptoms (n = 107) was established with the ICC_(1,3) = 0.81, p < .001. Known-groups (r = 0.99, p < .001), convergent (r = 0.78, p < .001), and divergent (r = .06, p = 0.24) validity all demonstrated evidence of good construct validity.

CONCLUSIONS

Preliminary psychometric testing for a single-item VAS that measures goals of care in a sample of patients with advanced cancer met standard requirements for reliability and validity. While further testing with a larger sample size is recommended, the tool's use in the clinical area to assess cancer patients' goals of care is appropriate. Such a tool could facilitate goals of care discussions in the clinical area.

A glimpse into the psychological status of E.N.T inpatients in China: A cross-sectional survey of three hospitals in different regions

Objective

To determine whether E.N.T inpatients have a higher prevalence of mental illness than the general population and whether certain diseases are more likely to be associated with mental illness than other diseases.

Methods

This cross-sectional survey was conducted in the E.N.T departments of three hospitals in different cities in China. The psychological status of all consecutive adult inpatients was assessed within 1–2 days following hospital admission using the Symptom Checklist-90 (SCL-90), Zung Self-Rating Depression Scale (SDS) and Zung Self-Rating Anxiety Scale (SAS). Inpatients from the general surgery and pneumology departments at the same hospital were enrolled and surveyed as control groups.

Results

The 439 patients enrolled in the final analysis accounted for 88.0% of all E.N.T inpatients during the study period. Of these patients, 16.4% were in an anxious state and 79.5% were in a depressive state. The overall anxiety (41.7 ± 9.7) and depression (55.9 ± 29.2) scores were much higher than Chinese norm (29.8 ± 10.0 and 33.5 ± 8.6, respectively), and significant differences were observed (t = 20.89, P < 0.01 and t = 13.12, P < 0.01, respectively). Although 18.7% of the E.N.T patients were psychiatric distress, these patients scored lower on the SCL-90 than the Chinese norm. Furthermore, the patients in the E.N.T department had a higher prevalence of anxiety and depression than those in the general surgery department but a similar prevalence to those in the respiratory department.

Conclusion

Psychological distress, particularly anxiety and depression, are widespread in patients with otolaryngological diseases. Therefore, the identification and treatment of co-occurring psychiatric disorders in this high risk and clinically challenging group of patients are urgent in China.

Association Between Pulmonary Function and Asthma Symptoms

BACKGROUND

FEV₁ as a percentage of predicted (FEV₁%pred) is commonly measured in asthma clinical studies; however, reports vary on its association with asthma control instruments evaluating symptoms.

OBJECTIVE

Assess the association between FEV₁%pred and Asthma Control Questionnaire (ACQ) scores in a managed-care population with persistent asthma.

METHODS

Retrospective analysis of survey responses and spirometry results of patients (aged ≥12 years) with persistent asthma from the Observational Study of Asthma Control and Outcomes was done. Eligible patients received 4 identical surveys including the 5-item ACQ (ACQ-5)/6-item ACQ (ACQ-6) and completed spirometry in parallel. Longitudinal analyses, comparisons of change over time, and fixed- and random-effects regression analyses were conducted, with/without adjustment for covariates.

RESULTS

There were 1748 survey responses with valid spirometry results. In unadjusted models, coefficients for ACQ-5/ACQ-6 scores were not statistically significant and coefficient of determination (R²) was low (0.03). When adjusted for covariates, ACQ-5 and ACQ-6 scores were significantly associated with FEV₁%pred (P < .001) and R² increased to 0.11 and 0.12, respectively. In adjusted models, every 1-point increase in ACQ-5 and ACQ-6 scores was associated with a 1.7% and 1.9% decrease, respectively, in FEV₁%pred. Change in FEV₁%pred and change in ACQ-5/ACQ-6 scores were not significantly associated in regressions with/without covariates.

CONCLUSIONS

The weak and statistically insignificant association between FEV₁%pred and ACQ-5/ACQ-6 scores in unadjusted models suggests a high degree of unexplained variation between these measures. Results support the use of both symptoms and pulmonary function, rather than relying on one measure alone, to assess asthma control in clinical care and outcomes studies.

Mixed-methods content and sentiment analysis of adolescents' voice diaries describing daily experiences with asthma and self-management decision-making

BACKGROUND

Accurate symptom assessment remains challenging in teen populations. Little is known of usual symptom/response patterns, and self-reported paper diaries have traditionally low compliance rates. Therefore, we used concurrent digital voice diaries to capture daily asthma experiences.

OBJECTIVE

(a) To qualitatively explore usual symptom patterns and self-management responses and (b) to quantitatively explore relationships between symptom severity and sentiment scores (a marker of emotional response to events).

METHODS

Fourteen minority and nonminority teenagers (age 13-17) with controlled (50%) and uncontrolled asthma used digital recorders to report about their asthma once daily over 14 days. Dairy entries were coded for symptom frequency, severity, type, and self-management responses, while sentiment analysis was used to evaluate the emotional valence of diary entries and to explore whether increased symptom levels correlated with greater negative sentiment.

RESULTS

Symptom frequency and severity recorded in voice diaries were much higher than teens indicated at baseline and were discordant with clinical assessments of asthma control. Of 175 entries, teens had symptoms 69.1% of days (121/175) and severe symptoms on one-third of these. Atypical symptoms (coughing, throat clearing) were reported twice as often as traditional symptoms (wheezing, chest tightness) and often not recognized as asthma, but rather attributed to being "sick" (25.6% of symptom days). Teens frequently minimized symptoms, used rescue and controller medication inconsistently, and resorted to alternative strategies to manage symptoms. Sentiment was not significantly correlated with assessed control (β = 0.14, P = 0.28), but for teens reporting severe symptoms, sentiment scores decreased by 0.31 relative to teens without symptoms (P = 0.006).

CONCLUSIONS AND CLINICAL RELEVANCE

Teens may minimize symptoms and have greater symptom frequency and severity than is recognized by themselves or providers. Screening for specific symptoms including coughing, throat clearing, and respiratory illness may be needed to identify those experiencing burden from asthma.

Clinical Application of Enhanced Recovery After Surgery in Perioperative Period of Laparoscopic Colorectal Cancer Surgery

OBJECTIVE

To investigate the clinical application value of enhanced recovery after surgery (ERAS) combined with the laparoscopic technique in the radical resection of colorectal cancer.

METHODS

A total of 200 patients undergoing laparoscopic radical surgery for colorectal cancer from June 2014 to June 2017 were selected and randomly divided into ERAS group (n = 100) and conventional (CON) group (n = 100). The ERAS group adopted enhanced recovery approach after surgery for perioperative treatment, while the CON group adopted a CON approach. The operation time, blood loss, first exhaust time, first defecation time, extubation time, complication rate (incision infection, pneumonia, gastric retention, anastomotic leakage, intestinal obstruction, etc.), scores of visual analog scale (VAS) 1, 3, and 7 days after surgery, and nutritional status (albumin, total protein) 1, 3, and 7 days after surgery were compared and analyzed.

RESULTS

Compared with the CON group, the ERAS group had significantly shorter first exhaust time, first defecation time, and extubation time (all P < .05). The incidence of overall complications in the ERAS group was less than those in the CON group (P < .05); and albumin and total protein were significantly higher in the ERAS group than in the CON group (both P < .05).

CONCLUSIONS

ERAS combined with laparoscopic techniques for the treatment of colorectal cancer is a safe and feasible practice. It not only promoted the recovery of gastrointestinal function but also improved the perioperative nutritional status of patients.

Care and treatment of a rare Mycobacterium avium complex-infected wound: a case report

An unusual presentation of Mycobacterium avium complex (MAC), unlikely to be encountered in an outpatient dermatology setting, was diagnosed in a patient without an immunodeficiency. A 47-year-old woman, who was immunocompetent and had no risk factors, presented with a full-thickness, infected wound (large amounts of purulent exudate and severe pain) on her back, which had been present for two months. She was diagnosed as having an MAC infection, using a DNA microarray chip method. The patient underwent wound drainage and a fresh silver-containing dressing was applied daily for two months. Although systemic antibiotics were given for one week and anti-tuberculous medication for one month, there was no response. She also complained of bloating, nausea, loss of appetite and other problems, apparently due to drug-induced liver damage, confirmed by laboratory tests. Based on her characteristics and a literature review related to MAC infection, we implemented an individualised, holistic care protocol for the patient that included a daily diet of appropriate fresh vegetables and fruits, and adequate high-quality protein, aerobic exercises for two hours per day, and sleep for 6-8 hours per day, to alleviate the iatrogenic liver damage, improve immune function and reduce the stress response. The wound continued treatment with sharp debridement as needed, and fresh antimicrobial silver-containing dressings every other day. Wound size was measured once a week to evaluate the effects. The wound healed after 48 days, and the patient was followed-up for 18 months at the outpatient wound care centre and through social media. No recurrence or scar hyperplasia was observed.

Verifying the validity and reliability of the Japanese version of the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Scale

Background

Pediatric patients, especially in the preverbal stage, cannot self-report intensity of pain therefore several validated observational tools, including the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Scale, have been used as a benchmark to evaluate pediatric pain. Unfortunately, this scale is currently unavailable in Japanese, precluding its widespread use in Japanese hospitals.

Objectives

To translate and verify the validity and reliability of the Japanese version of the FLACC Behavioral Scale.

Method

Back-translation was first conducted by eight medical researchers, then an available sample of patients at the University of Tsukuba Pediatric Intensive Care Unit (from May 2017 to August 2017) was enrolled in a clinical study. Two researchers evaluated the validity of the translated FLACC Behavioral Scale by weighted kappa coefficient and intraclass correlation coefficients (ICC). Observational pain was simultaneously measured by the visual analog scale (VAS obs) and reliability was evaluated by correlation analysis.

Result

The original author approved the translation. For the clinical study, a total of 121 observations were obtained from 24 pediatric patients. Agreement between observers was highly correlated for each of the FLACC categories (Face: κ = 0.85, Leg: κ = 0.74, Activity: κ = 0.89, Cry: κ = 0.93, Consolability: κ = 0.93) as well as the total score (Total: κ = 0.95,). Correlation analysis demonstrated a good criterion validation between the FLACC scale and the VAS obs. (r = 0.96)

Conclusion

Our Japanese version of the FLACC Behavioral Scale shows high validity and reliability.
