RESUMEN

BACKGROUND: The cost-effectiveness of interventions has attracted increasing interest among researchers. Although web-based and home-based psychoeducational interventions have been developed to improve first-time mothers' postnatal health outcomes, very limited studies have reported their cost-effectiveness. OBJECTIVE: The aim of this study was to evaluate the cost-effectiveness of web-based and home-based postnatal psychoeducational interventions for first-time mothers during the early postpartum period. METHODS: A randomized controlled 3-group pretest and posttest design was adopted, and cost-effectiveness analysis from the health care's perspective was conducted. A total of 204 primiparas were recruited from a public tertiary hospital in Singapore from October 2016 to August 2017 who were randomly allocated to the web-based intervention (n=68), home-based intervention (n=68), or control (n=68) groups. Outcomes of maternal parental self-efficacy, social support, postnatal depression, anxiety, and health care resource utilization were measured using valid and reliable instruments at baseline and at 1 month, 3 months, and 6 months after childbirth. The generalized linear regression models on effectiveness and cost were used to assess the incremental cost-effectiveness ratios of the web-based and home-based intervention programs compared to routine care. Projections of cumulative cost over 5 years incurred by the 3 programs at various coverage levels (ie, 10%, 50%, and 100%) were also estimated. RESULTS: The web-based intervention program dominated the other 2 programs (home-based program and routine care) with the least cost (adjusted costs of SGD 376.50, SGD 457.60, and SGD 417.90 for web-based, home-based, and control group, respectively; SGD 1=USD 0.75) and the best improvements in self-efficacy, social support, and psychological well-being. When considering the implementation of study programs over the next 5 years by multiplying the average cost per first-time mother by the estimated average number of first-time mothers in Singapore during the 5-year projection period, the web-based program was the least costly program at all 3 coverage levels. Based on the 100% coverage, the reduced total cost reached nearly SGD 7.1 million and SGD 11.3 million when compared to control and home-based programs at the end of the fifth year, respectively. CONCLUSIONS: The web-based approach was promisingly cost-effective to deliver the postnatal psychoeducational intervention to first-time mothers and could be adopted by hospitals as postnatal care support.

RESUMEN

BACKGROUND: Overweight, obesity, and associated comorbidities are a pressing global issue among children of all ages, particularly among low-income populations. Rapid weight gain (RWG) in the first 6 months of infancy contributes to childhood obesity. Suboptimal sleep-wake patterns and gut microbiota (GM) have also been associated with childhood obesity, but little is known about their influences on early infant RWG. Sleep may alter the GM and infant metabolism, and ultimately impact obesity; however, data on the interaction between sleep-wake patterns and GM development on infant growth are scarce. In this study, we aim to investigate associations of infant sleep-wake patterns and GM development with RWG at 6 months and weight gain at 12 months. We also aim to evaluate whether temporal interactions exist between infant sleep-wake patterns and GM, and if these relations influence RWG. METHODS: The Snuggle Bug/ Acurrucadito study is an observational, longitudinal study investigating whether 24-h, actigraphy-assessed, sleep-wake patterns and GM development are associated with RWG among infants in their first year. Based on the Ecological Model of Growth, we propose a novel conceptual framework to incorporate sleep-wake patterns and the GM as metabolic contributors for RWG in the context of maternal-infant interactions, and familial and socio-physical environments. In total, 192 mother-infant pairs will be recruited, and sleep-wake patterns and GM development assessed at 3 and 8 weeks, and 3, 6, 9, and 12 months postpartum. Covariates including maternal and child characteristics, family and environmental factors, feeding practices and dietary intake of infants and mothers, and stool-derived metabolome and exfoliome data will be assessed. The study will apply machine learning techniques combined with logistic time-varying effect models to capture infant growth and aid in elucidating the dynamic associations between study variables and RWG. DISCUSSION: Repeated, valid, and objective assessment at clinically and developmentally meaningful intervals will provide robust measures of longitudinal sleep, GM, and growth. Project findings will provide evidence for future interventions to prevent RWG in infancy and subsequent obesity. The work also may spur the development of evidence-based guidelines to address modifiable factors that influence sleep-wake and GM development and prevent childhood obesity.

RESUMEN

OBJECTIVES: To describe changes in sleep patterns during the coronavirus disease 2019 (COVID-19) pandemic, develop profiles according to these patterns, and assess sociodemographic, economic, COVID-19 related, and sleep and mental health factors associated with these profiles. DESIGN, SETTING, AND PARTICIPANTS: A 25-minute online survey was distributed worldwide through social media from 5/21/2020 to 7/1/2020. MEASUREMENTS: Participants reported sociodemographic/economic information, the impact of the pandemic on major life domains, insomnia and depressive symptoms, and changes in sleep midpoint, time-in-bed, total sleep time (TST), sleep efficiency (SE), and nightmare and nap frequency from prior to during the pandemic. Sleep pattern changes were subjected to latent profile analysis. The identified profiles were compared to one another on all aforementioned factors using probit regression analyses. RESULTS: The sample of 991 participants (ages: 18-80 years; 72.5% women; 60.3% residing outside of the United States) reported significantly delayed sleep midpoint, reductions in TST and SE, and increases in nightmares and naps. Over half reported significant insomnia symptoms, and almost two-thirds reported significant depressive symptoms. Latent profile analysis revealed 4 sleep pattern change profiles that were significantly differentiated by pre-pandemic sleep patterns, gender, and various COVID-19-related impacts on daily living such as severity of change in routines, and family stress and discord. CONCLUSIONS: In an international online sample, poor sleep and depressive symptoms were widespread, and negative shifts in sleep patterns from pre-pandemic patterns were common. Differences in sleep pattern response to the COVID-19 crisis suggest potential and early targets for behavioral sleep health interventions.

RESUMEN

BACKGROUND: Exercise is recommended as a principal treatment for individuals with knee osteoarthritis (KOA). However, the best choice for an optimal exercise program able to promote long-term compliance in KOA patients is not clear. This study aims to compare the effect of combined exercise (CE: quadriceps strengthening exercises (QSE) and Baduanjin qigong training (BDJ)) versus QSE alone and BDJ alone on older adults with KOA. METHODS: A three-arm, quasi-experimental trial with repeated measurements was used. As a cluster randomized trial, participants from three community centers were assigned respectively to QSE group, BDJ group and CE group. We assessed pain intensity, physical function, self-efficacy, and health-related quality-of-life (HRQoL) using standardized instruments at baseline, 3 months and 6 months follow-up. RESULTS: One hundred and twenty-eight participants with KOA aged over 60 completed the study. Over the 6 months, there were significant group interaction effects on pain intensity (F = 28.888, P < 0.001), physical function (F = 26.646, P < 0.001), and self-efficacy (F = 22.359, P < 0.001), and, based on a short form-12 item health survey questionnaire (SF-12), physical component summary (F = 7.470, P < 0.001), and mental component summary (F = 10.207, P < 0.001). Overall, the CE group exhibited significantly greater improvement in all outcomes when compared to the QSE group and the BDJ group. CONCLUSIONS: CE treatment is more effective than QSE and BDJ in pain relief, increasing physical function, improving self-efficacy, and raising quality-of-life in community-dwelling KOA older adults. Moreover, it promotes long-term compliance in KOA community patients. TRIAL REGISTRATION: Chinese Clinical Trails Registry number ChiCTR2000033387 (retrospectively registered).

RESUMEN

OBJECTIVES: To review the evidence and determine the effectiveness of smartphone-based self-management interventions on self-efficacy, self-care activities, health-related quality of life, glycated hemoglobin, body mass index (BMI), and blood pressure (BP) levels of adults with type 2 diabetes mellitus . METHODS: A systematic search of five databases (PubMed, Embase, Cochrane, CINAHL and Scopus) was conducted. Studies published in English from January 2007 to January 2018 were considered. Only randomized controlled trials (RCTs) of smartphone-based self-management interventions for patients with type 2 diabetes mellitus that reported any of the study outcomes were included. Two reviewers independently screened the studies, extracted data and assessed the quality of the studies. Meta-analyses were conducted for the different study outcomes. RESULTS: A total of 26 articles, consisting of 22 studies with 2645 participants, were included in the review. The results from meta-analysis on the studies revealed that as compared to control group, participants received smartphone-based self-management intervention had better self-efficacy with large effect size of 0.98 (P < 0.001), self-care activities with effect size of 0.90 (P < 0.001), health related quality of life with effect size of 0.26 (p=0.01), and lower glycated hemoglobin (pooled MD=-0.55; p<0.001). Subgroup analyses were also conducted for self-efficacy as significant heterogeneity was present among the studies. The effects on BMI and BP were not statistically significant. CONCLUSIONS: Smartphone-based self-management interventions appear to have beneficial effects on self-efficacy, self-care activities and health-relevant outcomes for patients with type 2 diabetes mellitus. However, more research with good study design is needed to evaluate the effectiveness of smartphone-based self-care interventions for T2DM.

RESUMEN

The objective of the study is to examine the 90-day readmission rate and identify the predictors for 90-day readmissions at a geriatric ward in a tertiary hospital in Singapore. A secondary analysis of case-control data was performed. Data of patients discharged from a geriatric ward between January 2015 and January 2016 were retrieved from an existing data set. Out of 564 index admissions involving older adults, the 90-day geriatric readmission rate was 10.1%. Activities of daily living dependency (odds ratio [OR]: 0.988, 95% confidence interval [CI]: [0.978, 0.999]) and living with the spouse (OR: 2.988, 95% CI: [1.388, 6.432]) were identified as significant predictors of 90-day geriatric readmissions. The study suggests that rehabilitation to restore the geriatric patient's ability to perform daily activities and adequate caregiver training for the spouse are essential in reducing geriatric readmissions. Also, postdischarge follow-up with both the patient and caregiver can greatly reduce the risk of readmission in geriatric patients.

RESUMEN

Gout is a chronic disease that is on a rising trend and greatly affects one's physical and psychosocial well-being. The aim of this study was to explore patients' perceptions of living with gout. A descriptive qualitative study was conducted and 15 adults with gout were interviewed face-to-face between December 2014 and January 2015. Thematic analysis was used to analyze the transcribed data. The experiences of patients with gout were found to revolve around four themes: emotional experiences with gout, disruptions in daily lives, interactions with doctor, and coping with gout using internal and external resources. The in-depth understanding of the patients' experiences indicates a need to provide holistic patient education and to involve family members to create nurse-led support groups and to raise public awareness regarding gout.

RESUMEN

OBJECTIVE: To investigate diet adherence, medication adherence and self-care behaviour among patients with chronic heart failure (CHF) in a multi-ethnic society and identify the significant factors associated with their diet and medication adherence. METHODS: A cross-sectional descriptive correlational study was conducted with a convenience sample of 107 patients with CHF recruited from two cardiology wards of a public tertiary hospital in Singapore. Study variables were measured using the Dietary Sodium Restriction Questionnaire, the Medication Adherence Rating Scale-5 items and the European Heart Failure Self-care Behaviour Scale-12 items. RESULTS: Our sample reported positive attitudes towards diet adherence, poor self-care behaviour, and good medication adherence. The multiple linear regression results indicated that lower income, Chinese ethnicity, diabetic complications, current smoking, lower New York Heart Association classification I and II, and poorer self-care behaviour predicted poorer diet adherence. In addition, absence of hypertension, having non-myocardial infarction as a cause of CHF, and moderately diminished ejection fraction were identified as significant predictors of poorer medication adherence. CONCLUSION: The findings from this study have established the need to improve current education and rehabilitation programmes for patients with CHF by addressing those factors significantly influencing their adherence to diet and medication.

RESUMEN

BACKGROUND: Besides physical and mental changes from childbirth, first-time mothers are also confronted with challenges associated with the demands of adapting to their roles as new parents. While positive effects of home-based psychoeducation intervention for mothers have been demonstrated, limited studies have developed and examined more accessible and cost-effective web-based psychoeducational interventions for mothers. OBJECTIVE: To examine the effectiveness of web-based and home-based postnatal psychoeducational interventions for first-time mothers during the early postpartum period. METHODS: A randomized controlled three-group pre-test and post-tests experimental design was adopted. Data were collected over five months, from October 2016 to August 2017, in a public tertiary hospital in Singapore from 204 primiparas who were randomly allocated to the web-based psychoeducation group, the home-based psychoeducation group, or the control group. The measured outcomes included maternal parental self-efficacy, social support, psychological well-being, satisfaction with postnatal care, and cost-effectiveness evaluation. Data were collected at four time points: the baseline, and three post-tests at one month, three and six months post-delivery. RESULTS: When compared to the control group, the web-based intervention improved self-efficacy at post-test 1 (mean difference = 2.68, p = 0.028) and reduced postnatal depression at post-test 3 (mean difference = -1.82, p = 0.044), while the home-based intervention did not show significant effect on these two outcomes at all post-tests. Both web-based and home-based interventions helped mothers to get better social support at all post-tests than those in the control group. Mothers in both web-based and home-based intervention groups were more satisfied with the postnatal care than those in the control group at all post-test time points (except for web-based group at post-test 1). There were no differences in anxiety scores among the three groups. When compared to the home-based intervention, the web-based intervention showed noninferior effect on all outcomes at all post-tests. CONCLUSION: The web-based intervention had better effects on improving self-efficacy, social support, and postnatal depression, which should be introduced to first-time mothers for better postnatal care.

RESUMEN

AIM: The aim of this study was to develop and examine the effectiveness of a 4-week Mobile Health (mHealth) programme using the smartphone app Care4Heart on awareness, knowledge, perceived stress, and a heart-related lifestyle among working population in Singapore. DESIGN: A quasi-experimental single group pretest and repeated post-test design. METHODS: A total of 160 nonhealth-related working adults were recruited from February 2016-April 2016. The Care4Heart app was installed on the participants' phones. Outcome measures, including the Heart Disease Fact Questionnaire-2, the Behavioral Risk Factor Surveillance System, and the Perceived Stress Scale were collected online at baseline, 4th week, and 6th month from baseline. RESULTS: Compared with the baseline, the participants had significantly higher total mean scores for awareness and knowledge of coronary heart disease (CHD) after study intervention at 4 weeks and 6 months from baseline. However, there were no significant differences in perceived stress levels and heart-related lifestyle behaviours before and after the intervention. CONCLUSIONS: The study contributed some evidence that the mHealth app helped to improve awareness and knowledge of CHD. IMPACT: Coronary heart disease remains one of the major causes of death and disability. It imposes a heavy financial burden on working adults. However, working adults were less able to identify the risk factors and adopt healthy lifestyles due to gaps in knowledge and awareness. This study demonstrated some effects of a mHealth programme in improving awareness and knowledge of CHD among the working population. mHealth provides a potential avenue for primary prevention of CHD.

RESUMEN

BACKGROUND: Despite the increasing use of implantable cardioverter defibrillators (ICDs) as a preventive approach for high-risk patients with arrhythmias, little is known about the perceptions of ICD recipients regarding these devices and their impact on quality of life. OBJECTIVES: To explore perceptions towards quality of life, coping strategies, and learning needs of patients living with ICDs in Singapore. METHODS: 16 participants (age ranges 52 to 84 years old) were purposively recruited and interviewed individually for this exploratory qualitative study. Data collected was analyzed using thematic analysis. RESULTS: Seven themes emerged: experiencing ICD shocks, ambivalent "love-hate" relationship with ICD, receiving support from healthcare professionals and social networks, attaining acceptance and returning to normalcy, physical coping, emotional coping, and readiness and need for enhanced patient education. CONCLUSIONS: With an insight to the perceptions of ICD recipients in Singapore, future practice can focus on addressing their concerns and improve post-implantation quality of life.

RESUMEN

BACKGROUND: In addition to recuperating from the physical and emotional demands of childbirth, first-time mothers are met with demands of adapting to their social roles while picking up new skills to take care of their newborn. Mothers may not feel adequately prepared for parenthood if they are situated in an unsupported environment. Postnatal psychoeducational interventions have been shown to be useful and can offer a cost-effective solution for improving maternal outcomes. OBJECTIVE: The objective of this study was to examine the effectiveness and cost-effectiveness of Web-based and home-based postnatal psychoeducational programs for first-time mothers on maternal outcomes. METHODS: A randomized controlled three-group pre- and posttests experimental design is proposed. This study plans to recruit 204 first-time mothers on their day of discharge from a public tertiary hospital in Singapore. Eligible first-time mothers will be randomly allocated to either a Web-based psychoeducation group, a home-based psychoeducation group, or a control group receiving standard care. The outcomes include maternal parental self-efficacy, social support, psychological well-being (anxiety and postnatal depression), and cost evaluation. Data will be collected at baseline, 1 month, 3 months, and 6 months post-delivery. RESULTS: The recruitment (n=204) commenced in October 2016 and was completed in February 2017, with 68 mothers in each group. The 6-month follow-up data collection was completed in August 2017. CONCLUSIONS: This study may identify an effective and cost-effective Web-based postnatal psychoeducational program to improve first-time mothers' health outcomes. The provision of a widely-accessed Web-based postnatal psychoeducational program will eventually lead to more positive postnatal experiences for first-time mothers and positively influence their future birth plans.

RESUMEN

Esophageal carcinoma is one of the most common malignancies in China. Previous studies reported that matrix metalloproteinases (MMPs) have important roles in the progression and invasion of numerous types of solid tumors. Among the MMPs, MMP-2 has been closely associated with tumor growth and invasion. In the present study, a short hairpin RNA (shRNA) lentiviral expression vector targeting the MMP-2 gene was constructed in order to observe the inhibitory effect of MMP-2 gene silencing on the growth of the KYSE150 esophageal carcinoma cell line in vivo. Three small hairpin RNA sequences targeting MMP-2 were designed and cloned into lentiviral vectors. Following transfection of the lentiviral vectors into KTSE150 cells, MMP-2 mRNA and protein expression levels were examined by reverse transcription-quantitative polymerase chain reaction and western blotting, and the growth rate of cells was analyzed by MTT assays. Subsequently, tumor growth was assessed in nude mice. Lentivirus-mediated RNA interference effectively inhibited the expression of MMP-2 mRNA and protein in KYSE150 esophageal carcinoma cells, and suppressed the growth of esophageal carcinoma cells in vivo. The results of the present study suggested that lentivirus-mediated gene therapy targeting MMP-2 may be an attractive strategy for the treatment of esophageal carcinoma and justifies the performance of further studies on the application of lentivirus vectors to cancer gene therapy.

RESUMEN

BACKGROUND: Bochdalek hernia is a type of congenital diaphragmatic hernia that typically presents in childhood, while this diseases is extremely rare in adults. CASE PRESENTATION: We review a case of a 63-year-old man with a left-sided Bochdalek hernia who was experiencing occasional pain at the left side of his chest for 8 months. The diagnosis of Bochdalek hernia was made by chest computed tomography. A part of the retroperitoneal adipose tissue was herniated into the left thoracic cavity through the diaphragmatic defect. The hernia was treated via video-assisted thoracoscopic surgery and he made an uneventful recovery. CONCLUSIONS: We report a rare case of a left-sided Bochdalek hernia for which our patient was treated successfully via video-assisted thoracoscopic surgery. Even though rare, this disorder should be recognised, examined and treated appropriately to avoid complications.

RESUMEN

OBJECTIVES: The purpose of this study was to investigate the correlation between multi-slice computed tomographic perfusion imaging (CTPI) parameters and immunohistologic markers of angiogenesis in esophageal squamous cell carcinoma (ESCC). METHODS: Fifty patients with histologically proven esophageal squamous cell carcinoma were enrolled in this study. All subjects underwent multi-slice CT perfusion scan. The hemodynamic parameters of vascular tumor, including blood volume (BV), blood flow (BF), mean transit time (MTT) and permeability surface (PS) were generated. All the ESCC specimens were stained immunohistochemically to identify CD31 for quantification of microvessel density (MVD). CTPI parameters were correlated with MVD by using Pearson correlation analysis. RESULTS: The value of CT perfusion parameters of ESCC were as follows: BF 116.71 ± 47.59 ml/100 g/min, BV 6.74 ± 2.70 ml/100 g, MTT 6.42 ± 2.84 s, PS 13.82 ± 6.25 ml/100 g/min. The mean MVD of all 50 tumor specimens was 34.44 ± 19.75. The PS values were significantly higher in ESCC patients with involvement of lymph node than those without involvement of lymph node (p < 0.01). Blood volume and permeability surface were positively correlated with MVD (p < 0.01), whereas no significant correlation was observed between MVD and BF or between MVD and MTT. CONCLUSIONS: Blood volume and permeability surface were positively correlated with MVD. CTPI could reflect the angiogenesis in ESCC.

RESUMEN

The number of empty-nest elderly is on the rise, especially in rural areas of China. The empty-nest elderly were concerned from social and demographic perspective, but researches on mental health issues of the aged were still rare in China. To clarify the prevalence of depression among empty-nest elderly in a rural area of YongZhou, Hunan and evaluate the impact of social support, coping style and socio-demographic factors on depression of the empty-nest elderly, with the goal of decreasing the rate of depression in empty-nest elderly, a questionnaire survey was conducted on 415 elderly persons. The determined prevalence of depressive symptoms was 74.46%. The empty-nest group, in comparison with the non-empty nest group, had higher levels of depression. Multivariate linear regression analysis showed associations between depressive symptoms and negative coping style, support utilization, religious beliefs, economic status, marital status and subjective support. The results suggested that the strategy to alleviate the depression in empty-nest elderly can be considered by the society, village committee, the family members and the empty-nest elderly subjects themselves, which could control effectively the incidence of depression.
