ObjectiveEsophagogastroduodenoscopy (EGD) is the pivotal procedure in the diagnosis of upper gastrointestinal lesions. However, there are significant variations in EGD performance among endoscopists, impairing the discovery rate of gastric cancers and precursor lesions. The aim of this study was to construct a real-time quality improving system, WISENSE, to monitor blind spots, time the procedure and automatically generate photodocumentation during EGD and thus raise the quality of everyday endoscopy.DesignWISENSE system was developed using the methods of deep convolutional neural networks and deep reinforcement learning. Patients referred because of health examination, symptoms, surveillance were recruited from Renmin hospital of Wuhan University. Enrolled patients were randomly assigned to groups that underwent EGD with or without the assistance of WISENSE. The primary end point was to ascertain if there was a difference in the rate of blind spots between WISENSE-assisted group and the control group.ResultsWISENSE monitored blind spots with an accuracy of 90.40% in real EGD videos. A total of 324 patients were recruited and randomised. 153 and 150 patients were analysed in the WISENSE and control group, respectively. Blind spot rate was lower in WISENSE group compared with the control (5.86% vs 22.46%, p<0.001), and the mean difference was −15.39% (95% CI −19.23 to −11.54). There was no significant adverse event.ConclusionsWISENSE significantly reduced blind spot rate of EGD procedure and could be used to improve the quality of everyday endoscopy.Trial registration numberChiCTR1800014809; Results.

Abstract Background: Bystander initiated resuscitation is essential. To encourage medical laypersons to perform resuscitation smartphone apps providing real-time guidance were invented. Are these apps a beneficial addition to traditional resuscitation training?Methods: In a randomized controlled trial impact of app usage on quality of resuscitation in a standardised simulated cardiac arrest scenario was assessed. In a previous study the app “HELP Notfall” was selected for this purpose. Six weeks after a standardised resuscitation training pupils encountered a simulated cardiac arrest (i) without app (control group); (ii) with facultative app usage (facultative group); (iii) with mandatory app usage (mandatory group).Results: 200 pupils attended this study with 74 pupils (37%) in control group, 65 (32,5%) in facultative group and 61 (30,5%) in mandatory group. Participants using the app in mandatory group had a significantly higher percentage of chest compressions with the correct compression rate (65.4% vs. 43.8%; p<0.01) and with correct compression depth (47.6% vs. 24.4%; p=0.001) than pupils of the control group. Participants of the mandatory group had a significant delay compared with control group regarding time until check for breathing (23 sec. vs. 12 sec., p<0.001), call for help (35 sec. vs. 20 sec., p<0.001) and first compression (68 sec. vs. 29 sec., p<0.001). Hands-off-time during compression tended to be shorter in mandatory group (0.5 sec.) compared with control group (1.5 sec.), (p=0.36).Conclusions: Smartphone apps offering real-time guidance in resuscitation are of mixed benefits. An improved quality of chest compression is countered by a delayed start of chest compressions. Both aspects have to be considered before recommending smartphone apps to support laypersons in bystander resuscitation as an addition to traditional hands-on training.

Abstract Background Bystander-initiated resuscitation is essential for surviving out-of-hospital cardiac arrest. Smartphone apps can provide real-time guidance for medical laypersons in these situations. Are these apps a beneficial addition to traditional resuscitation training? Methods In this controlled trial, we assessed the impact of app use on the quality of resuscitation (hands-off time, assessment of the patient’s condition, quality of chest compression, body and arm positioning). Pupils who have previously undergone a standardised resuscitation training, encountered a simulated cardiac arrest either (i) without an app (control group); (ii) with facultative app usage; or (iii) with mandatory app usage. Measurements were compared using generalised linear regression. Results 200 pupils attended this study with 74 pupils in control group, 65 in facultative group and 61 in mandatory group. Participants who had to use the app significantly delayed the check for breathing, call for help, and first compression, leading to longer total hands-off time. Hands-off time during chest compression did not differ significantly. The percentage of correct compression rate and correct compression depth was significantly higher when app use was mandatory. Assessment of the patient’s condition, and body and arm positioning did not differ. Conclusions Smartphone apps offering real-time guidance in resuscitation can improve the quality of chest compression but may also delay the start of resuscitation. Provided that the app gives easy-to-implement, guideline-compliant instructions and that the user is familiar with its operation, we recommend smartphone-guidance as an additional tool to hands-on CPR-training to increase the prevalence and quality of bystander-initiated CPR.

Abstract Background Because of the indiscriminate use of opioids during the perioperative period, opioid-free anesthesia (OFA) has been increasingly required. Nevertheless, the studies on the detailed techniques and effects of OFA are not sufficient. The Quality of Recovery-40 (QoR-40) questionnaire is a validated assessment tool for measuring recovery from general anesthesia. However, no study has used the QoR-40 to determine if OFA leads to better recovery than standard general anesthesia. Therefore, we aim to perform this study to determine the effects of OFA using dexmedetomidine and lidocaine on the quality of recovery as well as the various postoperative outcomes. Methods The participants (n = 78) will be allocated to one of the two groups; the study group will receive bolus and infusion of dexmedetomidine and lidocaine, and the control group will receive remifentanil infusion during general anesthesia for gynecological laparoscopy. The other processes including anesthetic and postoperative care will be performed similarly in the two groups. Intraoperative hemodynamic, anesthetic, and nociceptive variables will be recorded. Postoperative outcomes such as QoR-40, pain severity, and opioid-related side effects will be assessed. Additionally, an ancillary cytokine study (inflammatory cytokine, stress hormone, and reactive oxygen species) will be performed during the study period. Discussion This will be the first study to determine the effect of OFA, using the combination of dexmedetomidine and lidocaine, on the quality of recovery after gynecological laparoscopy compared with standard general anesthesia using remifentanil. The findings from this study will provide scientific and clinical evidence on the efficacy of OFA. Trial registration ClinicalTrials.gov NCT04409964. Registered on 28 May 2020

Introduction The * Equal contributors. health-status of heart failure patients can be improved to some extent by disease self-management. One method of developing such skills is telephone-based health coaching. However, the effects of telephone-based health coaching remain inconclusive. The aim of this study was to evaluate the effects of telephone-based health coaching for people with heart failure. Methods A total sample of 7186 patients with various chronic diseases was randomly assigned to either the coaching or the control group. Then 184 patients with heart failure were selected by International Classification of Diseases (ICD)-10 code for subgroup analysis. Data were collected at 24 and 48 months after the beginning of the coaching. The primary outcome was change in quality of life. Secondary outcomes were changes in depression and anxiety, health-related control beliefs, control preference, health risk behaviour and health-related behaviours. Statistical analyses included a per-protocol evaluation, employing analysis of variance and analysis of covariance (ANCOVA) as well as Mann-Whitney U tests. Results Participants’ average age was 73 years (standard deviation (SD) = 9) and the majority were women (52.8%). In ANCOVA analyses there were no significant differences between groups for the change in quality of life (QoL). However, the coaching group reported a significantly higher level of physical activity ( p = 0.03), lower intake of non-prescribed drugs ( p = 0.04) and lower levels of stress ( p = 0.02) than the control group. Mann-Whitney U tests showed a different external locus of control ( p = 0.014), and higher reduction in unhealthy nutrition ( p = 0.019), physical inactivity ( p = 0.004) and stress ( p = 0.028). Discussion Our results suggest that telephone-based health coaching has no effect on QoL, anxiety and depression of heart failure patients, but helps in improving certain risk behaviours and changes the locus of control to be more externalised.

PurposeAlthough there is a long history of use of semi-occluded vocal tract gestures in voice therapy, including phonation through thin tubes or straws, the efficacy of phonation through tubes has not been established. This study compares results from a therapy program on the basis of phonation through a flow-resistant tube (FRT) with Vocal Function Exercises (VFE), an established set of exercises that utilize oral semi-occlusions.MethodTwenty subjects (16 women, 4 men) with dysphonia and/or vocal fatigue were randomly assigned to 1 of 4 treatment conditions: (a) immediate FRT therapy, (b) immediate VFE therapy, (c) delayed FRT therapy, or (d) delayed VFE therapy. Subjects receiving delayed therapy served as a no-treatment control group.ResultsVoice Handicap Index (Jacobson et al., 1997) scores showed significant improvement for both treatment groups relative to the no-treatment group. Comparison of the effect sizes suggests FRT therapy is noninferior to VFE in terms of reduction in Voice Handicap Index scores. Significant reductions in Roughness on the Consensus Auditory-Perceptual Evaluation of Voice (Kempster, Gerratt, Verdolini Abbott, Barkmeier-Kraemer, & Hillman, 2009) were found for the FRT subjects, with no other significant voice quality findings.ConclusionsVFE and FRT therapy may improve voice quality of life in some individuals with dysphonia. FRT therapy was noninferior to VFE in improving voice quality of life in this study.

BACKGROUND: Asthma is common and is often poorly controlled in adolescent subjects.OBJECTIVE: To determine the impact of an age-specific asthma program on asthma control, particularly on exacerbations of asthma requiring emergency department treatment, and on the quality of life of adolescents with asthma.METHODS: The present randomized, controlled trial included patients who were 15 to 20 years of age and had visited emergency departments for management of their asthma. The interventional group attended an age-specific asthma program that included assessment, education and management by a team of asthma educators, respiratory therapists and respiratory physicians. In the control group, spirometry was performed, and the patients continued to receive usual care from their regular physicians. The outcomes were assessed by a questionnaire six months after entry into the study.RESULTS: Ninety-three subjects entered the study and were randomly assigned to the intervention or control group. Of these, only 62 patients were available for review after six months. Subjects in both the control and the intervention groups showed a marked improvement in their level of asthma control, reflected primarily by a 73% reduction in the rate of emergency department attendance for asthma. Other indexes of disease control, including disease-specific quality of life, as assessed by questionnaires, were improved. There was, however, no discernible difference between the subjects in the two groups, with the exception of an improvement in favour of the intervention group in the symptom (actual difference 0.7, P=0.048) and emotional (actual difference 0.8, P=0.028) domains of the asthma quality of life questionnaire. The overall quality of life score favoured the intervention group by a clinically relevant difference of 0.6, but this difference did not reach statistical significance (P=0.06).CONCLUSIONS: Although all subjects demonstrated a significant improvement in asthma control and quality of life, the improvement attributable to this intervention was limited to two domains in disease-specific quality of life.

Abstract Background Considering the prevalence of infertility in the community and the consequences of failure of infertility treatments on women’s mental health, interventions that can control stress, anxiety and depression in infertile women with a history of IVF failure will be very helpful. This study aimed to determine the effects of hope-oriented group counseling on mental health (primary outcome) and quality of life (QoL) (secondary outcome) of women with failed IVF cycles. Method This randomized controlled trial was conducted on 60 women with failed IVF cycles visiting Infertility Clinic at Al-Zahra Teaching Hospital of Tabriz- Iran. Participants were allocated to the intervention group (n = 30) and control group (n = 30) based on a randomized block design. Hope-oriented group counseling was provided to the intervention group in six 45–60 min sessions (once a week). The control group only received routine care to undergo another IVF cycle. The Depression Anxiety Stress Scale-21 (DASS-21) and the SF-12 Quality of Life Scale were filled out by interviewing the participants before the intervention and one week and one month after the intervention. After intervention 26 participants in each group were included in the analysis. Results There was no significant difference between the intervention and control groups in the socio-demographic profile of participants (P > 0.05). The post-intervention mean score of stress (adjusted mean difference = − 1.7, 95% confidence interval: − 3.2 to − 0.3, P = 0.018) and depression (adjusted mean difference = − 1.3, 95% confidence interval: − 4.7 to − 1.5, P < 0.001) was significantly lower in the intervention group compared to the control. Although the mean anxiety score was lower in the intervention group compared to the control, the difference between them was not statistically significant (adjusted mean difference = − 1.1, 95% confidence interval: − 2.6 to 0.4, P = 0.153). The mean score of QoL was significantly higher in the intervention group than that of the control group (adjusted mean difference = 6.9, 95% confidence interval: 5.1 to 8.8, P < 0.001). Conclusion Hope-oriented group counseling was effective in reducing stress and depression and improving QoL in women with failed IVF cycles. It is recommended to use this counseling approach, along with other methods, to improve the mental health of women with failed IVF cycles.

BACKGROUND Lack of physical activity (PA) and sedentary behaviors are leading risk factors for non-communicable diseases (NCD). Web-based interventions are effective in increasing PA in older adults and in NCD patients. In many countries a course of spa therapy is commonly prescribed to NCD patients and represents an ideal context to initiating lifestyle changes. OBJECTIVE The main objective of this study was to evaluate in NCD patients the effectiveness of an intervention combining an individual face-to-face coaching during spa therapy and, when returning home, a web- and smartphone-based PA program including a connected wrist pedometer and a connected weighing scale, on the achievement of physical activity guidelines (PAG) 12 months after the end of spa therapy. METHODS This was a 12-month, prospective, parallel-group, randomized controlled trial. Patients were enrolled during spa therapy and randomized 1:1 to intervention or control group who received usual advices about PA. From the end of spa therapy, PA, weight, waist circumference, and quality of life of the participants in both groups, were assessed by phone every 2 months. Primary outcome was meeting PAG (PA≥600 METs) at 12 months after the end of spa therapy. Secondary outcomes were: meeting current PAG at 6 months of follow-up; sedentary time, weight and waist circumference, PA and quality of life, at 6 and 12 months. Objective use data of the web-and smartphone-based PA program were collected. Analytic methods include intention-to-treat and constrained longitudinal data analyses. RESULTS The study sample was 228 patients (female : 77.2% (176/228), mean age: 62.4 years (SD 6.7), retired: 53.9% (123/228), mean BMI = 28.2 kg.m-2 (SD 4.2)). No group differences were found for any baseline variable. At 12 months, the proportion of patients achieving PAG was significantly higher in intervention group versus control group (81% vs 67% respectively, OR = 2.34 (95% CI 1.02- 5.38; P=.045). No difference between intervention and control group was found neither in achieving PAG at 6 months nor for sedentary time, weight and waist circumference, at 6 and 12 months. Regarding quality of life, the physical component subscale score was significantly higher at 12 months in intervention group versus control group (mean difference: 4.1 (95% CI 1.9-6.3; P<.001). The mean duration use of the program was 7.1 months (SD 4.5). Attrition rate during the first 2 months of the program was 20.4% (23/113) whereas 39.8% (45/113) of the participants used the program for at least 10 months. CONCLUSIONS The results showed significantly more participants meeting PAG at one year in the intervention group compared to controls. A course of spa therapy offers the ideal time and setting to implement education in PA. Digital coaching seems to be more efficient than usual coaching for increasing the level of PA and decreasing sedentariness on the long term.

Abstract Background Long-term complaints after caesarean section, such as postmenstrual spotting, dysmenorrhea, dyspareunia, or chronic pelvic pain, are frequently described in relation to the presence of a niche. A post-caesarean niche is defined as an indentation in the myometrium at the site of the uterine scar. Two independent prospective cohort studies reported that the presence of a niche after caesarean section increases the risk of postmenstrual spotting for more than 2 days from 15 to 30%. Postmenstrual spotting may be caused by a mechanical outflow problem, with the retention of menstrual blood in a niche, or by the accumulation of blood because of impaired uterine contractions at the site of the niche. Additionally, newly formed fragile vessels in the niche may play a role in the formation of blood or fluid in the niche and uterine cavity. Objective The aim of this study was to compare the effectiveness of a hysteroscopic niche resection versus no treatment in women with postmenstrual spotting and a uterine caesarean scar defect. Methods This trial is a randomised controlled trial that provides evidence for the (cost) effectiveness of hysteroscopic resection of a niche versus expectant management in women with niche related postmenstrual spotting. It was carried out on 28 cases divided into two equal group. The study was conducted at Ain Shams University on the women reporting postmenstrual spotting after a caesarean section. The primary outcome was the number of days of postmenstrual spotting 6 months after randomization. Secondary outcomes were spotting at the end of menstruation, intermenstrual spotting, dysuria, sonographic niche measurements, quality of life, women’s satisfaction, sexual function, and additional therapy. Outcomes were measured at 3 months and, also at 6 months after randomization. Results The results of this study show a significant improvement in interventional group after 3 months more than the control group in bleeding micturition characteristics which includes total days of spotting, spotting end of menstruation, intermenstral spotting, discomfort from spotting, dysmenorrhea and daily pain during micturition, after 6 months the two group improved but the interventional group was significantly higher than control group. Regarding the radiological assessment it was found that there was a significant improvement in intervention group more than the control group after 3 months, also the control group improved after 6 months also, but the intervention groups was significantly higher than the control group. The quality of life show a significant increasing in intervention group more than the control group after 3 months of intervention, at the end of follow up the intervention group was significantly higher in quality of life more than the control group. Conclusion A hysteroscopic niche resection reduces postmenstrual spotting, and the discomfort from spotting, compared with expectant management after 3 months of follow-up in women with a niche with a residual myometrium of at least 3 mm.

Objective To investigate the effects of kinesio taping and cold therapy on pain, edema, range of motion, muscle strength, functional level and quality of life in patients with total knee arthroplasty. Design Randomised controlled trial. Setting A university hospital. Subjects One-hundred patients were included. Intervention Patients were allocated into three groups; control group, kinesio group and cold therapy group. The control group received a standard rehabilitation program. Kinesio taping group received two fan-shaped kinesio taping bands and cold therapy group received cold packs in addition to the standard rehabilitation program. Main measures The outcome measures were pain, edema, range of motion, muscle strength, functional level and quality of life. Participants were assessed at preoperative, discharge and postoperative third month. Results The groups were similar at preoperative. A significant difference was determined in terms of pain in kinesio taping group compared to the control group at the discharge. Cold therapy was efficient in reducing postoperative swelling but kinesio taping had no significant effects on swelling control. There was no difference between the groups in terms of range of motion, muscle strength, functional level and quality of life. The groups were similar in all parameters at the postoperative third month measurements. Conclusion Fan-shaped kinesio taping is an effective technique in terms of postoperative pain relief. Cold therapy is an effective method in terms of edema control. Kinesio taping and cold therapy has no specific beneficial effect on functional level, muscle strength and quality of life compared to control group.
