ABSTRACT

BACKGROUND: The proportion of smokers making quit attempts and the proportion of smokers successfully quitting have been decreasing over the past few years. Previous studies have shown that smokers with high self-efficacy and motivation to quit have an increased likelihood of quitting and staying quit. Consequently, further research on strategies that can improve the self-efficacy and motivation of smokers seeking to quit could lead to substantially higher cessation rates. Some studies have found that gamification can positively impact the cognitive components of behavioral change, including self-efficacy and motivation. However, the impact of gamification in the context of smoking cessation and mobile health has been sparsely investigated.

OBJECTIVE: This study aims to examine the association between perceived usefulness, perceived ease of use, and frequency of use of gamification features embedded in smoking cessation apps on self-efficacy and motivation to quit smoking.

METHODS: Participants were assigned to use 1 of the 2 mobile apps for a duration of 4 weeks. App-based questionnaires were provided to participants before app use and 2 weeks and 4 weeks after they started using the app. Gamification was quantitatively operationalized based on the Cugelman gamification framework and concepts from the technology acceptance model. The mean values of perceived frequency, ease of use, and usefulness of gamification features were calculated at midstudy and end-study. Two linear regression models were used to investigate the impact of gamification on self-efficacy and motivation to quit.

RESULTS: A total of 116 participants completed the study. The mean self-efficacy increased from 37.38 (SD 13.3) to 42.47 (SD 11.5) points and motivation to quit increased from 5.94 (SD 1.4) to 6.32 (SD 1.7) points after app use. Goal setting was perceived to be the most useful gamification feature, whereas sharing was perceived to be the least useful. Participants self-reported that they used the progress dashboards the most often, whereas they used the sharing feature the least often. The average perceived frequency of gamification features was statistically significantly associated with change in self-efficacy (β=3.35; 95% CI 0.31-6.40) and change in motivation to quit (β=.54; 95% CI 0.15-0.94) between baseline and end-study.

CONCLUSIONS: Gamification embedded in mobile apps can have positive effects on self-efficacy and motivation to quit smoking. The findings of this study can provide important insights for tobacco control policy makers, mobile app developers, and smokers seeking to quit.

ABSTRACT

BACKGROUND: Cognitive training can improve cognition in healthy older adults.

OBJECTIVE: The objectives are to evaluate the implementation of community-based computerized cognitive training (CCT) and its effectiveness on cognition, gait, and balance in healthy older adults.

METHODS: A single-blind randomized controlled trial with baseline and follow-up assessments was conducted at two community centers in Singapore. Healthy community-dwelling adults aged 55 years and older participated in a 10-week CCT program with 2-hour instructor-led group classes twice a week. Participants used a mobile app to play games targeting attention, memory, decision making, visuospatial abilities, and cognitive flexibility. Implementation was assessed at the participant, provider, and community level (eg, reach, implementation, and facilitators and barriers). Effectiveness measures were the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), Color Trails Test 2 (CTT-2), Berg Balance Scale, and GAITRite walkway measures (single and dual task gait speed, dual task cost, and single and dual task gait variability index [GVI]).

RESULTS: A total of 94 healthy community-dwelling adults participated in the CCT program (mean age 68.8 [SD 6.3] years). Implementation measures revealed high reach (125/155, 80.6%) and moderate adherence but poor penetration of sedentary older adults (43/125, 34.4%). The effectiveness data were based on intention-to-treat (ITT) and per-protocol (PP) analysis. In the ITT analysis, single task GVI increased (b=2.32, P=.02, 95% CI [0.30 to 4.35]) and RBANS list recognition subtest deteriorated (b=-0.57, P=.01, 95% CI [-1.00 to -0.14]) in both groups. In the PP analysis, time taken to complete CTT-2 (b=-13.5, P=.01, 95% CI [-23.95 to -3.14]; Cohen d effect size = 0.285) was faster in the intervention group. Single task gait speed was not statistically significantly maintained in the intervention group (b=5.38, P=.06, 95% CI [-0.30 to 11.36]) and declined in the control group (Cohen d effect size = 0.414). PP analyses also showed interaction terms for RBANS list recall subtest (b=-0.36, P=.08, 95% CI [-0.75 to 0.04]) and visuospatial domain (b=0.46, P=.08, 95% CI [-0.05 to 0.96]) that were not statistically significant.

CONCLUSIONS: CCT can be implemented in community settings to improve attention and executive function among healthy older adults. Findings help to identify suitable healthy aging programs that can be implemented on a larger scale within communities.

ABSTRACT

OBJECTIVE: To investigate the use of microwave ablation (MWA) with cooling urethral perfusion and with no perfusion (MWA-UP and MWA-NP, respectively) for prostate gland ablation in canine cadavers.

ANIMALS: Cadavers of 18 sexually intact male dogs.

PROCEDURES: After technique refinement in 2 cadavers, laparotomy with ultrasound-guided MWA-UP (n = 8) or MWA-NP (8) of the prostate gland was performed in 16 cadavers. Normograde cystourethroscopy was performed before and after treatment; recorded images were reviewed in a blinded manner for scoring of urethral mucosal discoloration and loss of integrity. Difficulty with cystoscope insertion was recorded if present. Excised prostate glands were fixed for serial sectioning, gross measurements, and calculation of percentage ablation. Percentages of prostate tissue necrosis from MWA, denuded urethral mucosa, and depth of epithelial surface loss in an adjacent section of the colon were estimated histologically. Variables of interest were statistically analyzed.

RESULTS: Difficulty with cystoscope insertion after treatment was significantly more common and scores for urethral mucosal discoloration and loss of integrity were significantly higher (indicating more severe lesions) for the MWA-NP group than for the MWA-UP group. The histologically assessed percentage of denuded urethral mucosa was also greater for the MWA-NP group. Overall median percentage prostate gland ablation was 73%; this result was not associated with prostate gland volume or chronological order of treatment.

CONCLUSIONS AND CLINICAL RELEVANCE: MWA-UP induced subtotal thermal necrosis of prostate glands in canine cadavers while limiting urethral mucosal injury. Further study is required to optimize the technique and evaluate its safety and efficacy in vivo as a future curative-intent treatment for prostatic tumors in dogs.

ABSTRACT

OBJECTIVES: The aim of this study was to compare the characteristics of fresh and stored feline red blood cells (RBCs) after passage through an 18 μm microaggregate filter.

METHODS: Nine cats were recruited for a single blood donation using an open collection system. A simulated transfusion using a syringe driver and microaggregate filter was performed over 2 h with half the blood on the day of donation and the other half after 35 days of storage. Differences in haematological parameters, haemolysis percentage and osmotic fragility (OF) were compared on the day of donation pre-filter passage (D0-) vs day of donation post-filter (D0+) or day 35 storage pre-filter (D35-) and post-filter (D35+). Blood was cultured at D0+ and D35+.

RESULTS: There were no statistically significant differences in the D0- vs D0+ comparisons. There were statistically significant (P <0.05) increases in haemolysis percentage, red cell distribution width (RDW) percentage and mean OF, and decreases in packed cell volume (PCV), RBC count, haemoglobin and haematocrit for D0- vs D35-. The same was found for D0- vs D35+ with the addition of a significant increase in mean cell haemoglobin (MCH). For D35- vs D35+ only MCH significantly increased. At day 35, 6/9 units had haemolysis percentages that exceeded 1%. This increased to 8/9 of stored units post-filter passage. All blood units cultured negative.

CONCLUSIONS AND RELEVANCE: Fresh RBCs exhibited no in vitro evidence of injury following passage through an 18 μm microaggregate filter. Increased MCH was observed in the stored blood and may represent haemolysis induced by the filter. All other changes can be explained by storage lesion rather than filter passage. The findings highlight the importance of blood banking quality controls and the need for further research to assess the effects of transfusion technique, specifically filter passage, on storage lesion-affected feline blood.

ABSTRACT

Introduction: Individual acupuncture (AP) is the gold standard method of AP delivery for cancer-related pain; however, costs can be prohibitive. Group AP allows four to six patients to be treated in a single session. This study sought to examine the cost-utility of group AP compared with individual AP from a patient perspective. Materials and Methods: Effectiveness and cost data from a noninferiority randomized trial of group versus individual AP for cancer-related pain were used. In the trial, 74 patients were randomly assigned to individual or group AP treatments twice per week for 6 weeks. The EuroQol five-dimension five level questionnaire (EQ-5D-5L) was used to assess health-related quality of life, and the EQ-5D Utility Index was used as a composite measure constituted of five domains (mobility, self-care, usual activities, anxiety-depression, and pain-discomfort). Linear mixed models were used to compare the change in EQ-5D-5L states pre-post intervention between the two arms. A cost-utility analysis was performed in terms of the incremental costs per additional quality-adjusted life year (QALY) gained. Results: Group AP participants experienced more significant relief in the pain-discomfort subscale of the EQ-5D-5L measure compared with individual AP participants (group × time, F = 6.18; p = 0.02). The effect size on pain-discomfort for group AP (d = 0.80) was higher than that of individual AP (d = 0.34). There were no significant differences between the two study arms for other subscales of the EQ-5D-5L over time. QALYs at 6 weeks were slightly higher for group AP (0.020) compared with individual AP (0.007) leading to an incremental QALY gained by the group arm of 0.013, but this difference was not statistically significant (p = 0.07). The cost of delivering AP treatment for the group arm over 6 weeks ($201.25) was nearly half of the individual arm ($400). Conclusions: Group AP was superior to individual AP in cancer patients. These findings have implications for the use of group AP in low-resource settings and in health care systems where AP for cancer patients is not covered by public health insurance.

ABSTRACT

Gout arthritis commonly affects joint regions by deposition of crystals, promoting functional damage mainly during periods of exacerbation. Cryotherapy is a commonly used resource to contain inflammatory processes, however, its use during a gout crisis is not yet well understood. Therefore, the objective was to evaluate the parameters of Wistar rats submitted to an experimental gout model and treated with dual cryotherapy protocol. Twenty-one male Wistar rats were used, separated into three groups: control group (CG), lesion group (LG), and lesion + cryotherapy group (LCG). Gout model induction was through intra-articular injection, with urate crystal solution, in the right knee and cryoimmersion treatment was performed for 20 minutes at a temperature of 5° ± 2°C. Seven evaluations and two treatment moments were performed, and the following parameters were analyzed: joint edema, grip strength, joint disability, motor function, and leukocyte migration through synovial lavage. In the statistical analysis we used SPSS 20.0 with Generalized Linear Models, with least significant difference posttest, always with 5% significance level. The treatment reduced edema, promoted strength recovery, and was effective in reducing total leukocytes in the synovial fluid. No difference was observed between the injured groups for joint disability and motor function. Cryotherapy promoted edema reduction and increased pelvic limb grip strength in Wistar rats during the acute period.

ABSTRACT

BACKGROUND.: Strategies to reduce anxiety prior to injection procedures are not well understood. The purpose is to determine the effect of a meditation monologue intervention delivered via phone/mobile application on pre-injection anxiety levels among patients undergoing a clinical injection. The following hypothesis was tested: patients who listened to a meditation monologue via phone/mobile application prior to clinical injection would experience less anxiety compared to those who did not.

METHODS.: A prospective, randomized controlled trial was performed at an orthopedics and sports medicine clinic of a tertiary level medical center in the New England region, USA. Thirty patients scheduled for intra- or peri-articular injections were randomly allocated to intervention (meditation monologue) or placebo (nature sounds) group. Main outcome variables were state and trait anxiety inventory (STAI) scores and blood pressure (BP), heart rate, and respiratory rate.

RESULTS.: There were 16 participants who were allocated to intervention (meditation monologue) while 14 participants were assigned to placebo (nature sounds). There was no interaction effect. However, a main time effect was found. Both state anxiety (STAI-S) and trait anxiety (STAI-T) scores were significantly reduced post-intervention compared to pre-intervention (STAI-S: p = 0.04, STAI-T: p = 0.04). Also, a statistically significant main group effect was detected. The pre- and post- STAI-S score reduction was greater in the intervention group (p = 0.028). Also, a significant diastolic BP increase between pre- and post-intervention was recorded in the intervention group (p = 0.028), but not in the placebo group (p = 0.999).

CONCLUSION.: Listening to a meditation monologue via phone/mobile application prior to clinical injection can reduce anxiety in adult patients receiving intra- and peri-articular injections. Registration: ClinicalTrials.gov NCT02690194.

ABSTRACT

BACKGROUND.: Mycobacterium tuberculosis has become the leading cause of morbidity and death in humans worldwide. Thus, genetic variability of the host plays a major role in human susceptibility to the pathogen, among others. Therefore, the objective of this finding was to assess the association of genetic polymorphisms of cytokines with tuberculosis infection.

METHOD.: A cross-sectional study was conducted between January and May 2018. Five ml of whole blood was collected and extracted the genomic DNA through simple salting out method. The patterns of genetic polymorphism were determined by amplification refractory method PCR using specific primers. Finally, the PCR run on electrophoresis of agarose gel and the band was visualized under UV light. A logistical regression model has been adapted to assess the association of genetic polymorphisms with tubercular infection. In order to determine the association between the explanatory and outcome variable, the odds ratio with 95% CI was calculated. P < 0.05 is a statistically significant value.

RESULT.: In present study, the frequency of TNF-α -308 G allele and GG genotype OR (95% CI)= 0.20 (0.11-0.37), and OR (95% CI)= 0.29 (0.18-0.46)), respectively) and IFN-γ +874 A allele and AA genotype OR (95% CI)= 3.80 (2.11-6.86) and (OR (95% CI)= 1.61(1.13-2.28), respectively) were significantly associated with tuberculosis incidence. In contrast, there is no significant correlation between IL-10 -1082 A and AA of allele and genotype, respectively in tuberculosis patients (p > 0.05) was evident.

CONCLUSION.: From our finding, the genetic variability of TNF-α -308 A and IFN-γ +874 alleles are the potent host genetic risk factors associated with tuberculosis infection.

ABSTRACT

BACKGROUND: Priority setting in healthcare that aims to achieve a fair and efficient allocation of limited resources is a worldwide challenge. Sweden has developed a sophisticated approach. Still, there is a need for a more detailed insight on how measures permeate clinical life. This study aimed to assess physicians’ views regarding (1) impact of scarce resources on patient care, (2) clinical decision-making, and (3) the ethical platform and national guidelines for healthcare by the National Board of Health and Welfare (NBHW).

METHODS: An online cross-sectional questionnaire was sent to two groups in Sweden, 2016 and 2017. Group 1 represented 331 physicians from different departments at one University hospital and group 2 consisted of 923 members of the Society of Cardiology.

RESULTS: Overall, a 26% (328/1254) response rate was achieved, 49% in group 1 (162/331), 18% in group 2 (166/923). Scarcity of resources was perceived by 59% more often than ‘at least once per month,’ whilst 60% felt less than ‘well-prepared’ to address this issue. Guidelines in general had a lot of influence and 19% perceived them as limiting decision-making. 86% professed to be mostly independent in decision-making. 36% knew the ethical platform ‘well’ and ‘very well’ and 64% NBHW’s national guidelines. 57% expressed a wish for further knowledge and training regarding the ethical platform and 51% for support in applying NBHW’s national guidelines.

CONCLUSION: There was a need for more support to deal with scarcity of resources and for increased knowledge about the ethical platform and NBHW’s national guidelines. Independence in clinical decision-making was perceived as high and guidelines in general as important. Priority setting as one potential pathway to fair and transparent decision-making should be highlighted more in Swedish clinical settings, with special emphasis on the ethical platform.

ABSTRACT

INTRODUCTION: The prevalence of appendiceal endometriosis ranges from 0.4% to 22%. The carcinoid tumor is the most common neoplasm of the appendix, with incidence ranging from 0.3% to 0.9%. Appendix lesions develop in up to 22% of women with deep infiltrative endometriosis. Even though these are most likely endometriosis, carcinoid tumors should always be considered. The aim of this review was to assess the prevalence of appendiceal carcinoid tumors and appendiceal endometriosis in patients undergoing gynecologic surgery, its association with endometriosis, and related symptoms.

EVIDENCE ACQUISITION: We included retrospective and prospective studies that assessed women who underwent appendicectomy in the past 20 years for appendiceal endometriosis and/or appendix carcinoid tumor confirmed by histological analysis. Results were reported as relative and absolute frequencies. Due to the heterogeneity of included studies, a statistical analysis (meta-analysis) was not performed.

EVIDENCE SYNTHESIS: The prevalence of appendiceal endometriosis was 15.2% in patients who underwent surgery for pelvic endometriosis and 11.4% in those who underwent benign gynecological surgery. Conversely, carcinoid tumors of the appendix were present in 2.4% of endometriosis patients and 1.3% of other benign gynecological surgeries.

CONCLUSIONS: The rates of carcinoid tumors in patients with endometriosis are the same as in the general population. Given the risk of a malignant appendiceal tumor, in all gynecological surgeries, especially those for endometriosis, the appendix should be inspected and removed if it has an abnormal appearance.
