A quality evaluation of nursing intervention studies in China's Mainland: From 1979 to 2012

Background:The number of papers published in the field of nursing practice has greatly increased in recent years in China's Mainland,yet the quality of these papers is highly variable.There has been no attempt to comprehensively estimate the overall quantity and quality of these papers.Objectives:To systematically retrieve nursing intervention studies published in simplified Chinese from 1979 to 2012,critically appraise their quality,and provide suggestions for future development.Methods:All of the papers were retrieved from China Biology Medicine disc database.The preliminary screening of retrieved publications was performed prior to conducting a rigorous quality evaluation of the remaining publications.10 characteristics would be included in consideration in quality evaluations.Results:69,150 papers were retrieved according to searching strategy.7391 of them were included after preliminary screening and appraised critically.Among the 10 characteristics considered in quality evaluations,the lowest ratings were observed for the factors of“utilisation of blind method”(13 articles),“description of loss of follow-up”(499 articles),“appropriate calculation of sample size”(511 articles)and“randomised assignment of patients to treatments”(652 articles).Conclusions:Chinese papers published in the field of nursing practice have increased over time,but improvements remain needed to ensure that thorough studies with high-quality research methodologies are being performed.Future nursing researchers should not only improve the design of their intervention studies but also clearly describe the methodology they used,especially in group randomisation,blinded research designs,and estimations of required sample sizes.

Effects of a theory of planned behavior-based intervention on breastfeeding behaviors after cesarean section:A randomized controlled trial

Objectives:To examine the efficacy of an intervention based on the theory of planned behavior(TPB)in improving breastfeeding behavior among women with cesarean sections(C-sections).Methods:This research was a randomized controlled trial.Women with planned elective C-sections were recruited to participate in a randomized controlled trial between June and September 2020.One hundred thirty-two women were divided randomly into the intervention(n=66)and control group(n=66)by systematic random sampling.In the intervention group,an intervention project was implemented after Keywords:Breastfeeding Cesarean section Intervention studies Theory of planned behavior the C-section to establish positive breastfeeding attitudes,cultivate supportive subjective norms,enhance perceived behavioral control,and strengthen breastfeeding intention to change behaviors.Those in the control group received routine pre-and post-delivery care.Exclusive breastfeeding rate and breast problem were collected at 5 days,2 weeks,and 1 month after C-section.The modified Breastfeeding Attrition Prediction Tool(BAPT)on the first day in the hospital,two weeks,and one month after C-section and Numerical Rating Scale(NRS)24 h postoperatively were used to compare the intervention effect between the two groups.Results:After the intervention,the intervention group had significantly higher exclusive breastfeeding rates than the control group at five days(86.4%vs.60.6%),two weeks(77.3%vs.57.6%),and one month(74.2%vs.50.0%)after the C-section.Besides,the intervention group was less likely to have sore nipples at five days(6.1%vs.18.2%in the control group,P<0.05)and two weeks(9.1%vs.12.1%in the control group,P<0.05).After two weeks of intervention,attitude scores(90.64±8.31 vs.87.20±8.15,P<0.05),subjective norm scores(88.07±24.65 vs.79.42±19.47,P<0.05)and behavior control scores in the intervention group were significantly higher than those in the control group.After one month of intervention,attitude scores(90.34±10.35 vs.84.22±10.51,P<0.05)and behavior control scores(43.13±5.02 vs.39.15±4.69,P<0.05)in the intervention group were significantly higher than those in the control group,which resulted in the higher breastfeeding intention in the intervention group.Conclusion:This study indicated that the TPB-based interventions effectively improved women's breastfeeding behaviors after C-sections.

Effect of distinct psychological interventions on changes in selfreported distress,depression and loneliness among older adults during COVID-19

BACKGROUND Older adults have been considered a primary at-risk population during the coronavirus disease 2019(COVID-19)pandemic,and many efforts have been and still are directed toward supporting them and enhancing their capacity to cope with the pandemic.Evidence shows that by enhancing proactive coping abilities through psychological interventions,in which cognitive-behavioral and mindfulness techniques are taught and practiced effectively,these interventions have supported older adults throughout the pandemic.However,the underlying mechanisms by which specific intervention components affect various mental states such as distress,depression and loneliness among older adults remain unclear and warrant investigation.AIM To determine the effect of an intervention using cognitive-behavioral and mindfulness techniques on changes in distress,depression and loneliness.METHODS We performed a secondary analysis on data from a previous study in which community-dwelling older adults attended a short-term,internet-based intervention during the first COVID-19 wave in Israel.The intervention included seven sessions during which various cognitive-behavioral and mindfulness techniques were learned and practiced.In-session changes in psychological distress were measured using the Subjective Units of Distress Scale(SUDS),which participants rated at the beginning and end of each session.Participants also filled out questionnaires that evaluated levels of depression[Patient Health Questionnaire(PHQ-9)]and loneliness(UCLA loneliness Scale)prior to and after the entire intervention process.The effect of in-session changes in the SUDS on changes in post-intervention depression and loneliness levels were assessed,as a proxy for distinct technique effectiveness.RESULTS The findings indicated in-session differences in terms of a decrease in psychological distress(SUDS).Sessions that included relaxation exercises and guided imagery,as well as sessions that included cognitive restructuring and mindfulness meditation,demonstrated the largest decreases in in-session psychological distress(≥35%).Two multivariate regression models,one for levels of post-intervention depression(PHQ-9 score)and the other for levels of post-intervention loneliness(UCLA loneliness score),were fitted.The results revealed two statistically significant explanatory variables for depression:The SUDS difference for sessions in which cognitive restructuring and mindfulness meditation were practiced,beta=-0.25,95%CI:-1.23 to-0.1,and the pre-intervention level of depression,beta=0.62,95%CI:0.37-0.75.The second model for loneliness revealed only one significant explanatory variable:The SUDS difference for sessions in which relaxation and guided imagery were practiced,beta=0.41,95%CI:0.14-0.65.CONCLUSION Different psychological techniques seem to have different effects on distress,loneliness and depression.Understanding the pathways by which distinct techniques affect negative mental symptoms has implications for future intervention design.

Methodological quality(risk of bias) assessment tools for primary and secondary medical studies: What are they and which is better?

Methodological quality(risk of bias)assessment is an important step before study initiation usage.Therefore,accurately judging study type is the first priority,and the choosing proper tool is also important.In this review,we introduced methodological quality assessment tools for randomized controlled trial(including individual and cluster),animal study,non-randomized interventional studies(including follow-up study,controlled before-and-after study,before-after/pre-post study,uncontrolled longitudinal study,interrupted time series study),cohort study,case-control study,cross-sectional study(including analytical and descriptive),observational case series and case reports,comparative effectiveness research,diagnostic study,health economic evaluation,prediction study(including predictor finding study,prediction model impact study,prognostic prediction model study),qualitative study,outcome measurement instruments(including patient-reported outcome measure development,content validity,structural validity,internal consistency,cross-cultural validity/measurement invariance,reliability,measurement error,criterion validity,hypotheses testing for construct validity,and responsiveness),systematic review and meta-analysis,and clinical practice guideline.The readers of our review can distinguish the types of medical studies and choose appropriate tools.In one word,comprehensively mastering relevant knowledge and implementing more practices are basic requirements for correctly assessing the methodological quality.

Motor-Cognitive Intervention in Mexican Older Adults

Two motor-cognitive interventions were implemented to evaluate their efficacy in cognitive improvement in Mexican older adults 65 years and more. The intervention group received a dance video games plus a cognitive task (dual-task);the comparison group received only the dance video game, in sessions of 45 minutes, 3 times a week, for 12 weeks. The Barthel Index and Lawton and Brody Index, the Center for Epidemiologic Studies Depression Scale-Revised were applied the Digit Span Test, the Stroop Test, and Color Trail Making. Gait parameters were assessed by GAITRite? electronic walkway (CIR Systems). The design was quasi-experimental. Sites were randomly assigned to intervention groups. The intervention group started with 32 participants and finished with 15;the comparison group started with 20 participants and finished with 18. Participants in the intervention group had to mimic the dance movement of a video game and, after the second week to name progressively three objects without stopping dancing. A multivariate repeated measures model (MANO-VA) was fit with four variables. A time-by-group interaction was observed in the Stroop test, and Digits Span Backwards was in favor of the dual task group. The Stroop test, Digit Span Backwards, gait speed, and step length showed effect time. Both groups improved in gait speed and step length by the end of the intervention. Results show it is feasible for Mexican older adults with little schooling to perform dual tasks and improve cognitive tasks and gait speed. Limitations were high attrition due to unforeseen situations and small sample size.

The effect of a urinary incontinence selfmanagement program for older women in South Korea:A pilot study

Background:Although self-management approaches have shown strong evidence of positive outcomes for urinary incontinence prevention and management,few programs have been developed for Korean rural communities.Objectives:This pilot study aimed to develop,implement,and evaluate a urinary incontinence self-management program for community-dwelling women aged 55 and older with urinary incontinence in rural South Korea.Methods:This study used a one-group pre-post-test design to measure the effects of the intervention using standardized urinary incontinence symptom,knowledge,and attitude measures.Seventeen community-dwelling older women completed weekly 90-min group sessions for 5 weeks.Descriptive statistics and paired t-tests and were used to analyze data.Results:The mean of the overall interference on daily life from urine leakage(pre-test:M=5.76±2.68,post-test:M=2.29±1.93,t=4.609,p<0.001)and the sum of International Consultation on Incontinence Questionnaire scores(pre-test:M=11.59±3.00,post-test:M=5.29±3.02,t=-5.881,p<0.001)indicated significant improvement after the intervention.Improvement was also noted on the mean knowledge(pre-test:M=19.07±3.34,post-test:M=23.15±2.60,t=7.550,p<0.001)and attitude scores(pre-test:M=2.64±0.19,post-test:M=3.08±0.41,t=5.150,p<0.001).Weekly assignments were completed 82.4%of the time.Participants showed a high satisfaction level(M=26.82±1.74,range 22e28)with the group program.Conclusions:Implementation of a urinary incontinence self-management program was accompanied by improved outcomes for Korean older women living in rural communities who have scarce resources for urinary incontinence management and treatment.Urinary incontinence self-management education approaches have potential for widespread implementation in nursing practice.

The effect of sustained, long-term changes in alcohol intake on cardiovascular risk

Objective: To investigate whether sustained long-term changes in alcohol intake are predictive of cardiovascular risk. Methods: The study population was a subpopulation of the five-year intervention study, Inter99 study, (1999-2006), Copenhagen, Denmark (n = 2117;30 - 60 years). Alcohol intake was assessed by questionnaires at baseline, one-, three- and five-year follow-up. The associations between sustained long-term changes in alcohol intake and cardiovascular risk factors (HDL and non-HDL cholesterol, systolic and diastolic blood pressure (BP);the absolute risk of ischemic heart disease (CRS)) at five-year follow-up were explored by linear regression models. The alcohol variables were tested for linear association with the response variable. Results: Sustained increased alcohol intake was significantly associated with increased CRS (β = 0.0028;P = 0.006) and a decreased HDL cholesterol (β = -0.0028;P = 0.005). Among participants with a moderate overall alcohol in-take at baseline increased alcohol intake was significantly associated with an increased plasma triglyceride (β = 0.0069;P = 0.04). No association with triglyceride was found for participants with a high alcohol intake. Change in wine intake was significantly negatively associated with changes in diastolic BP (β = 0.0015;P = 0.02). Conclusions: Sustained increase in the long-term intake of alcohol was a significant risk factor for an increased CRS, increased triglyceride level and decreased HDL cholesterol. Increased wine intake was associated with decreased diastolic BP.

Resistance Training in People at Risk of Developing Type 2 Diabetes and Their Experience of Health-Related Quality of Life

Background: Research indicates an association between impaired glucose metabolism and overweight, a serious public health problem involving an increased risk of Type 2 diabetes, related hypertension, and a reduced quality of life. Aim: The first aim is to assess different dimensions of Health-Related Quality of Life (HRQoL) in overweight individuals at risk of developing Type 2 diabetes compared to a normal population. The second aim is to examine the impact of resistance training on the pre-post HRQoL dimension scores of the intervention group. Methods: Eighteen participants were randomly assigned to one of the two resistance training groups. Group 1 engaged in supervised maximal resistance training (Bernstein inverted pyramid system: 5× 3 - 4, 60% - 85% of 1 Repetition Maximum (RM)), three days/week over four months, and Group 2 performed endurance resistance training (including lower weight loads and more repetitions over four months). The intervention consisted of eight exercises involving the entire body. The subjects completed the Short-Form Health Survey (SF-36) on HRQoL. The HRQoL scores of the norm population were higher than those of people at risk of developing Type 2 diabetes, and resistance training seemed to have a limited significant positive effect on the different HRQoL dimensions.

Initial experience of occluding special type patent ductus arterioses using the Amplatzer vascular plug

Background Occluders licensed for clinical use are not fit for some special Krichenko E patent ductus arterioses. The Amplatzer vascular plug I （AVP1） has not been licensed for use for closure of patent ductus arteriose. We report our initial experience to occluding special type patent ductus arterioses with the AVPI-a single lobe device of single layer Nitinol mesh for short vessel landing zones. Methods Patients referred with small and long Krichenko E patent ductus arterioses 1 mm to 3 mm in diameter underwent occlusion using AVPI. All cases underwent pre-, intra- and post-procedural echocardiography and chest X-ray at the completion of the procedure, the next day and at a 30-day, 3-month and 6-month follow-up visits. Device sizing for device waist diameter and length was based on aortography. Results From April 2008 to June 2012, 26 patients with a mean age of （7.6±8.0） years （range 6 months-32 years） and a mean weight of （23.8±14.8） kg （range 7-67 kg） underwent successful patent ductus arteriose closure. The mean ductus diameter was （2.1±0.7） mm （range 1-3 mm）. Transpulmonary （22/26） and transaortic approaches （4/26） were used. No persistent patency was observed after 24 hours and after one month. No device displacement, residual flow and iatrogenic coarctation of the aorta were observed after three months and six months. Conclusions The AVP1 makes it easy to close some Krichenko E patent ductus arterioses. Smaller delivery catheter profile and symmetric cylindrical device shape allow for use for small and long Krichenko E patent ductus arterioses 1 mm to 3 mm in diameter and small patients through transaortic approaches. Broader experience is required to further delineate device and patient selection as well as to document its long-term efficacy and safety.

Swine model of arterial bifurcation aneurysm

Objective To create an arterial bifurcation aneurysm model in swine and evaluate it with digital subtraction angiography (DSA).Methods Ten swine were used for constructing the arterial bifurcation aneurysm models. Seven pigs underwent subsequent intraarterial DSA. Both surgical procedure and transarterial angiography were carried out under anesthesia with mechanical ventilation after tracheal intubation.Results Bifurcation aneurysms were surgically created in ten animals. After surgical procedure, 2 pigs died from aneurysmal rupture and one died of anesthetic overdose. DSA was performed in all other 7 animals and it demonstrated 6 patent aneurysms and one occluded. Three of the 6 patent bifurcation aneurysms were wide necked and 3 were narrow necked.Conclusion Arterial bifurcation aneurysm model can be successfully constructed in swine. It will provide us with an in vivo model to observe and develop therapeutic devices, teach endovascular techniques, and study aneurysmal hemodynamics.
