Effectiveness of intergenerational participation on residents with dementia: A systematic review and meta-analysis.

AIM: This meta-analysis evaluated the effectiveness of intergenerational program participation for long-term care institution residents with dementia. DESIGN: A systematic review and meta-analysis. METHODS: Ten electronic databases were systematically searched until August 2020: CINAHL, the Cochrane Library, EBSCO, EMBASE, Ovid Medline, ProQuest, Psychology and Behavioral Sciences Collection, PubMed, Scopus, and Web of Science. The Joanna Briggs Institute tool (JBI tool) was used for the quality appraisal of the included publications, and Review Manager 5.3 was used for the meta-analysis. RESULTS: Thirteen articles were identified (1993-2015). Intergenerational program participation could improve the pleasure level and significantly reduce disengagement behaviours of residents with dementia. The intergenerational program intervention caused no apparent improvement in their quality of life, depression levels, and engagement levels.

Exploring diagnostic and prognostic predictive values of microRNAs for acute myocardial infarction: A PRISMA-compliant systematic review and meta-analysis.

OBJECTIVE: Previous investigations yielded inconsistent results for diagnostic and prognostic predictive values of MicroRNAs (miRNAs) for acute myocardial infarction (AMI). METHODS AND RESULTS: We systematically searched on PubMed and Web of Science for articles explored association of miRNAs and AMI published from January 1989 to March 2019. For diagnostic studies, a summary of sensitivity, specificity, positive likelihood ratios (PLR), negative likelihood ratios (NLR), and diagnostic odds ratio (DOR), which indicated the accuracy of microRNAs in the differentiation of AMI and no AMI, were calculated from the true positive (TP), true negative (TN), false positive (FP), and false negative (FN) of each study. In addition, the summary receive-operating characteristics (SROC) curve was constructed to summarize the TP and FP rates. For follow-up study, we computed hazard ratios (HRs) and 95% confidence intervals (CIs) for individual clinical outcomes. The meta-analysis showed a sensitivity [0.72 (95% CI: 0.61--0.81)] and specificity [0.88 (95% CI: 0.79--0.94)] of miR-1 for AMI. In addition, miR-133 showed a sensitivity [0.73 (95% CI: 0.55--0.85)] and specificity [0.88 (95% CI: 0.74--0.95)] for AMI. Moreover, the present study showed a sensitivity [0.83 (95% CI: 0.74--0.89)] and specificity [0.96 (95% CI: 0.82--0.99)] of miR-208 for AMI. A significant association was found between miR-208 and mortality after AMI (HR 1.09, 95% CI 1.01--1.18). It also indicated a sensitivity [0.84 (95% CI: 0.70--0.92)] and specificity [0.97 (95% CI: 0.87--0.99)] of miR-499 for AMI. CONCLUSIONS: Circulating miR-1, miR-133, miR-208, and miR-499 showed diagnostic values in AMI.

Effectiveness of Companion Robot Care for Dementia: A Systematic Review and Meta-Analysis.

BACKGROUND AND OBJECTIVES: Dementia and central nervous system degeneration are common problems in aging societies with regard to the number of people affected and total medical expenses. Socially assistive robotic technology has gradually matured; currently, most scholars believe it can be used as companions in long-term care facilities and to work as caregivers alongside staff to improve the social interaction and mental state of older adults and patients with dementia. Therefore, this study measured the effect of the duration of exposure to socially assistive robots in older adults with dementia. RESEARCH DESIGN AND METHODS: Seven databases were searched up to February 2019 through the consultation of appropriate Internet sites and the use of criteria lists recommended by relevant experts. Randomized controlled trials comparing socially assistive robot use with a control group in older adults with dementia and using at least one of the primary outcomes of agitation, depression, and quality of life were included. RESULTS: Thirteen randomized controlled trials were identified from 873 articles, 7 of which were included in the meta-analysis. The pooled effect estimate from 3 trials with 214 participants revealed that the pet-type robot improved patients' agitation level, with a standardized mean difference of -0.37 (95% CI: -0.64 to -0.10, p < .01) and no heterogeneity (I 2 = 0%). The results also revealed that length of each session and pet-type robot exposure time per week were associated with reduced depression levels (ß = -0.06, Q = 21.213, df = 1, p < .001 and ß = -0.019, Q = 7.532, df = 1, p < .01, respectively). However, the results for quality of life were nonsignificant. DISCUSSION AND IMPLICATIONS: Pet-type robot systems seem to be a potential activity in long-term care facilities for dementia care. Further research is warranted to establish a comprehensive intervention plan related to the use of pet-type robots.

Home care aides' attitudes to training on oral health care.

This study investigated home care aides' (HCAs) oral health care experience, knowledge, and their intention to receive professional training, to explain and predict factors of their intention to receive such training. This cross-sectional study collected data through a structured questionnaire. HCAs affiliated with home care agencies in Taichung, Taiwan were recruited through purposive sampling. A total of 487 questionnaires were distributed from September to December 2015 with 280 valid responses collected (57.4%).This study predicted the factors of HCAs' intention to receive oral health care training through a decision tree analysis. The decision tree model classified the respondents with an accuracy of 77.5%. The optimal predictor variable was oral health care knowledge (χ2 = 66.662, p < 0.0001). Among the low-scoring respondents on oral health care knowledge, 76.4% were classified in the "uninterested" group, whereas 84.8% of the high scorers were classified in the "interested" group. The second best predictor variable was whether oral health care is part of the job responsibility (χ2 = 7.979, p = 0.007). Among those who answered Yes, 92.9% were in the interested group, as were 76.5% of those who answered No. It is recommended to add "disease and oral care-related content" and "safety protection, assessment, and usage of oral care tools during practical oral care process" to the oral healthcare training course content for HCAs in order to improve HCAs' oral healthcare knowledge and oral care skills. These research findings are valuable and may be taken into account in the future development of the in-service educational training of oral healthcare for HCAs.

Aromatherapy intervention on anxiety and pain during first stage labour in nulliparous women: a systematic review and meta-analysis.

This systematic review and meta-analysis aimed to critically evaluate and summarise all available evidence derived from randomised clinical trials (RCTs) regarding aromatherapy's effects on labour pain and anxiety relief. Literature search was performed in MEDLINE/PubMed, Cochrane library, Cochrane Central Register of Controlled Trials (CENTRAL) and Scopus since their respective inception to January 2019. Additionally, Google Scholar was also searched to explore citations of eligible final studies which were subsequently included in the systematic review. The search strategy used was: (pregnancy or pregnant or prenatal or antenatal or perinatal or maternal) AND (aromatherapy or essential oils or aroma therapy). Per inclusion and exclusion criteria established by the current study, nine RCTs were included in the systematic review. Results from the current study suggested that aromatherapy significantly decreased pain and anxiety in the first stage of labour.IMPACT STATEMENTWhat is already known on this subject? Several studies have shown aromatherapy's effectiveness in relieving pain and anxiety for hospitalised patients and on relieving nausea and vomiting for women during pregnancy. Some results have further indicated that aromatherapy was effective in facilitating episiotomy healing and in reducing pain, fatigue and distress. Aromatherapy was also found to play a role in improving maternal moods; reducing post-caesarean pain; and preventing or mitigating stress, anxiety and depression after childbirth. Though most non-pharmaceutical pain management options were considered non-invasive and presumably safe for mothers and their foetuses, their exact efficacies remained unclear due to a lack of high quality evidence.What the results of this study add? This systematic review and meta-analysis summarises all evidence derived from RCTs wherein aromatherapy was performed as a supportive analgesic method during labour. Results of this meta-analysis identified more credible evidence validating that aromatherapy could significantly decrease labour pain both in early active and late active phases.What the implications are of these findings for clinical practice and/or further research? Availability of credible evidence supporting aromatherapy's effectiveness on reducing physiological and psychological stress during pregnancy and childbirth would be useful, both theoretically and practically, for all stakeholders concerned, such as pregnant women, medicine and midwifery students, midwives, nurses, gynaecologists and health policymakers.

Massage therapy for weight gain in preterm neonates: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVES: Weight gain is the main criterion for hospital discharge. This study measured the effectiveness of treating preterm neonates with massage therapy. DESIGN: Systematic review and meta-analysis of randomized controlled trials. DATA SOURCES: Web of Science, Ovid-Medline, CINAHL, ProQuest, and PubMed (up to July 24, 2018). STUDY SELECTION: Randomized controlled trials involving preterm infants with very-low-birth weight or low-birth-weight that examined the effect of massage therapy, and at least one outcome assessing infants' weight change or weight gain. RESULTS: Pooled effect estimate from 15 trials with 697 participants showed that massage therapy improved daily weight gain by 5.07 g/day (95% CI 2.19-7.94, p = 0.0005). More benefits were observed when preterm neonates received moderate pressure massage (5.60 g/day, 95% CI 2.64-8.56, p = 0.0002) than when receiving light-pressure therapy (1.08 g/day, 95% CI 0.29-1.86, p = 0.007). CONCLUSIONS: Massage therapy is beneficial for preterm infant weight gain.

Effects of Exercise on Sleep Quality in Pregnant Women: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

PURPOSE: Sleep quality was considered a priority concern facing pregnant women. Conventional wisdom argues that good sleep quality benefits pregnant women and their fetuses. The aim of this study is to assess the effects of a specific exercise program on the　sleep quality in pregnant women. METHODS: Searches were executed in seven databases since their inceptions until February 28, 2019, for randomized controlled trials evaluating the effects of an exercise program on the sleep quality and insomnia in pregnant women. A random-effects model was applied for meta-analysis, and odds ratio, mean differences (MDs), and 95% confidence intervals (CIs) are shown as parts of outcomes. RESULTS: Seven studies were included for meta-analysis. Compared with their not-exercising counterparts, analyses showed that regularly exercising women had significantly enhanced sleep quality, with an odds ratio of 6.21 (95% CI, 2.02-19.11;p = .001; I2 = 80.2%), with a standardized MD of -0.93 (95% CI, -1.19 to -0.67; p < .001; I2 = 30.0%). However, exercising women showed no significant insomnia improvement, with an standardized MD of -2.85 (95% CI, -7.67 to 1.98; p = .250; I2 = 97.0%), relative to their not-exercising counterparts. CONCLUSION: This research indicated that exercise has a positive impact on the sleep quality of pregnant women. Despite the aforementioned positive impact on sleep quality, the present study did not find evidence to support that exercise may also improve insomnia for pregnant women.

Horticultural Therapy in Patients With Dementia: A Systematic Review and Meta-Analysis.

BACKGROUND: World Health Organization has communicated that dementia as a public health priority in 2012. Behavioral and psychological symptoms of dementia are the main reason results in hospitalization of dementia patients. Horticulture is one of the favorite activity for many peoples to relax their minds. OBJECTIVES: To investigate psychological health benefits of horticulture intervention in dementia patients. METHODS: The databases including Cochrane Library, ProQuest, PubMed, EMBASE, EBSCO, Web of Science, and Ovid Medline were searched up to August 2017. RESULTS: Twenty-three articles for systematic review, whereas 8 articles were included in meta-analysis. Meta-analysis verified the beneficial effect of horticultural therapy (HT) on agitation level (standard mean difference: -0.59; P < .00001); increase time spent on activity engagement (mean differences [MD]: 45.10%, P < .00001); decrease time for doing nothing (MD: -29.36%, P = .02). CONCLUSIONS: Patients with dementia benefit from horticultural by alleviating their degrees of agitate behaviors, increasing time of engaging in activities and decrease time of doing nothing.

Value of ST-segment change in lead aVR in diagnosing left main disease in Non-ST-elevation acute coronary syndrome-A meta-analysis.

BACKGROUND: Previous researches proved that the ST-segment elevation (STE) in lead aVR had great significance on the prediction of severe left main lesion or serious multivessel lesions. The current research is to summarize the published data and evaluate the overall association of STE in lead aVR and left main coronary artery disease (LMD) in Non-ST-elevation acute coronary syndrome. METHODS: Literature searching was performed in the online database, and a systematic review was conducted based on the searched results. Meaningful STE in lead aVR was summarized and analyzed for odds ratio (OR) and 95% confidence intervals (95% CI). RESULTS: Twenty-seven articles were included for final data analysis. Compared with STE < 0.05, STE ≥ 0.05 mV was associated with a higher incidence rate of LMD (OR = 6.64, 95% CI: 4.80 ~ 9.17), and the degree of STE in lead aVR was significantly associated with LMD. Myocardial infarction was more likely to occur in patients with STE ≥ 0.05 mV than in patients with STE < 0.05 mV (OR = 3.12, 95% CI: 1.73 ~ 5.62). CONCLUSIONS: The STE in lead aVR and the degree of STE are independent predictors in diagnosing LMD or myocardial infarction.

Inequality in outpatient resource utilization among older adults during the 2007-2008 financial crisis: findings from Taiwan.

BACKGROUND: Equity in medical resource utilization is a crucial concern in countries with national health insurance systems. From the perspective of an active aging framework, public health insurance is one of the pillars of economic security, as suggested by the World Bank, to achieve the goal of social security for older adults. This study thus sought to quantify income-related inequality in national health insurance systems, especially during the global economic crisis of 2007-2008. METHODS: By employing the Taiwan National Health Interview Surveys (2005 and 2009) datasets, we analyzed the socioeconomic inequality of outpatient service utilization for older Taiwanese adults during the financial crisis of 2007-2008. We used corrected concentration indices (CCIs) to examine inequalities over time. Furthermore, we decomposed socioeconomic inequalities to reveal the contributions of determinant factors. The dependent variables related to whether participants had used outpatient services in the previous month, and the independent factors included individual's needs, enabling, predisposing, and environmental factors proposed by Andersen model. RESULTS: The sample consisted of 2415 observations in 2005 and 2554 observations in 2009. The income-related health care inequality was minor from pro-rich to pro-poor across the study duration, although the difference was insignificant (women: from a concentration index [CI] of 0.0256 in 2005 to a CI of - 0.0098 in 2009; men: from a CI of 0.0379 in 2005 to a CI of 0.0310 in 2009). We used a probit model to analyze the effect of explanatory factors on outpatient resource utilization by men and women. After other factors were controlled for, we found that that the income variable had a positive and significant effect on outpatient service utilization in 2009 and the absolute contribution of income to inequality notably increased from 0.0480 in 2005 to 0.3247 in 2009 for older women. CONCLUSIONS: In conclusion, Taiwan's National Health Insurance system guarantees the accessibility of health care services to older adults, but slight income-related inequality was maintained in the outpatient resource utilization of women during the 2007-2008 financial crisis. Close attention should be paid to the vulnerability of women during times of economic insecurity.

Evaluate five different diagnostic tests for dry mouth assessment in geriatric residents in long-term institutions in Taiwan.

BACKGROUND: Residents in long-term care (LTC) institutions require care plans to effectively resolve dry mouth. Simple and easily comprehensible dry mouth indices must be developed to assist care professionals in determining dry mouth among residents. Therefore, this study aim of the study was to evaluate five different diagnostic tests for dry mouth assessment. METHODS: A total of 568 residents were recruited from several LTC institutions in central Taiwan. The research instruments and tools comprised of the characteristics of the residents, state of oral health care, self-perceived ability to chew food, Taiwanese short-form of the Oral Health Impact Profile (OHIP-7 T), self-perceived levels of dry mouth, oral moisture checking, and a repetitive saliva swallowing test (RSST). The data collected were analyzed through demographic analysis, Correlation coefficient and chi-squared automatic interaction detection. RESULTS: Results of the decision tree analysis indicated that RSST results, tooth brushing frequency, and age were the three indices that exerted the greatest influence on oral moisture levels. Specifically, in residents with relatively high RSST results, a daily tooth brushing frequency > 1, and an age < 68 years exhibited more favorable oral moisture levels. The results indicated that residents' self-perceived oral status was not associated with their oral moisture levels. CONCLUSION: The three indices can be provided to LTC institutions for on-site assessment of dry mouth among residents to facilitate early detection of those with dry mouth.

Home-care aides' self-perception of oral health-care provision competency for community-dwelling older people.

OBJECTIVES: To investigate the circumstances in which home-care aides (HAs) provide oral health care to homebound patients and to examine the degree of comfort and knowledge that HAs have regarding their own skills in providing oral health care. METHODS: Seven home-care facilities in central Taiwan consented to participate in this cross-sectional study. The participants were selected through convenience sampling. A total of 312 effective responses were obtained (the effective response rate was 64.0%). SPSS, version 17, was used to perform statistical analyses, including descriptive statistics, factor analysis and multiple regression analysis. RESULTS: Oral health-care work had a minimal impact on the psychological burden of the HAs. However, factors affecting the self-perception of the HAs regarding their competency in oral health-care provision included 'whether oral health care is a part of home care' (ß = -0.195, P = 0.006), 'whether patients had difficulty chewing' (ß = -0.178, P = 0.001), 'vomiting during oral health care' (ß = 0.133, P = 0.001), 'having HA certification' (ß = 0.120, P = 0.030), 'whether premeal oral exercises were performed' (ß = 0.141, P = 0.012), 'finger biting during the provision of oral care' (ß = -0.115, P = 0.039) and 'time constraints for provision of care' (ß = 0.143, P = 0.042). CONCLUSIONS: Enhancing HAs' self-perception of their competency in oral health-care provision can help develop in-service training courses focused on oral health care for older adults, thereby further strengthening HAs' competency in oral health-care provision.

Relationship between emergency care utilization, ambient temperature, and the pollution standard index in Taiwan.

This study applied a vector error correction model to investigate the effects of ambient temperature (AT) and air quality index values on emergency care utilization (ECU). The Pollution Standards Index (PSI) and total suspended particulates (TSP) were used for analysis. Data were obtained from the National Health Insurance Research Database of the Ministry of Transportation and Communications and Ministry Environmental of Protection Administration of Taiwan. Data from January of 1998 to December of 2012 (180 months) were analyzed. Study results showed that, regardless of long-term equilibrium or short-term dynamics, a 1 °C increase in AT will decrease ECU, showing that AT strongly affects ECU. There were no significant corrections of long-term equilibrium of PSI and TSP on ECU. Only short-term TSP dynamics caused negative effects in the first ECU phase. Emergency care requires special monitoring of AT and TSP to respond to the increased number of high-risk patients consulting emergency departments.

Factors related to the decision-making for moving the older adults into long-term care facilities in Taiwan.

AIM: To investigate the relationships between demographic characteristics of the elderly, type of long-term care (LTC) facilities, and the reasons for moving into LTC facilities. METHODS: Research participants included people aged over 65 years, living in LTC facilities. A total of 1280 questionnaires were distributed to 111 LTC facilities in Taiwan; 480 questionnaires were retrieved, and 232 were included in the valid sample. The study used a non-linear canonical correlation analysis, which assesses the relationships among similar sets of categorical variables. RESULTS: The results showed that the older adults in quadrant I were characterized by being involved in the decision-making regarding the choice of LTC facilities and received economic support from their children. The older adults in quadrant II mainly lived in LTC facilities to receive medical care, whereas those in quadrant III typically included individuals with low income, who did not choose to live in LTC facilities. Furthermore, those in quadrant IV had positive cognitions associated with LTC facilities. CONCLUSIONS: We believe that the results of the present study will facilitate policy-making in the field of LTC, provide reference to the practitioners and the older adults, and identify the types of decisions older adults make when moving into LTC facilities, thus assisting older adults to improve their strategies regarding staying in LTC facilities.

Factors affecting institutionalized older peoples' self-perceived dry mouth.

PURPOSE: The purpose of this study was to determine the factors affecting institutionalized older peoples' self-perceived dry mouth. METHODS: This cross-sectional study was conducted on elderly residents at 22 long-term care facilities. A total of 165 questionnaires were returned from 13 senior citizen welfare institutions (SCWIs) and nine nursing homes. Multiple logistic regression analysis was used to analyze the data obtained. RESULTS: The results showed that the type of long-term care (LTC) facility, regular oral examinations, wearing dentures, and the ability to chew sticky foods affected self-perceived dry mouth. This study determined an association between the type of LTC facility where the participants lived and self-perceived dry mouth. CONCLUSIONS: The results indicated the importance of providing oral care in order to improve and prevent dry mouth among institutionalized older people living in SCWIs who do not undergo regular oral examinations, wear dentures, and have difficulty chewing sticky foods.

Clinical effectiveness, toxicity, and failure patterns of helical tomotherapy for postoperative oral cavity cancer patients.

BACKGROUND: The outcome of postoperative high- and intermediate-risk oral cavity cancer (OCC) patients receiving helical tomotherapy (HT) remains limited. MATERIALS AND METHODS: Between November 2006 and November 2012, 53 postoperative high- and intermediate-risk OCC patients treated with HT were enrolled. RESULTS: The 4-year locoregional, local, and regional control rates were 66%, 76.4%, and 94.3%, respectively. The 4-year locoregional control rates of oral tongue and buccal mucosa cancer were 88.3% and 37.1%, respectively (P=0.012). Eleven (20.8%) patients experienced locoregional failure. In-field failure occurred in six of 53 (11.3%) in the primary area and three of 53 (5.7%) in the regional lymph-node area. No marginal failure was noted. Two of 53 (3.8%) experienced out-of-field failure. The rates of grade 3 dermatitis, mucositis, and dysphagia were 11%, 34%, and 13%, respectively. No grade 3 xerostomia was noted. Grade 2 xerostomia was 33% at month 6 and declined to 0 at month 48. A rate of 56% of grade 2 trismus at month 6 was noted, and declined to around 30% after 2 years. No grade 3 trismus was noted after 2 years. CONCLUSION: HT as a postoperative modality provided satisfying results, especially for xerostomia and trismus, and was impressive in high- and intermediate-risk OCC patients receiving postoperative HT.

Decision-making factors affecting different family members regarding the placement of relatives in long-term care facilities.

BACKGROUND: The aim of this research was to investigate factors affecting different family members' decisions regarding the placement of relatives in long-term car (LTC) facilities in Taiwan. The objective was to investigate the correlations between family members' personal traits, the living conditions of residents in the LTC facilities, and family members' experiences with LTC facilities. METHODS: This study selected family members visiting residents in LTC facilities as research subjects and used a structured questionnaire to perform face-to-face interviews. This study used nonlinear canonical correlation analysis (OVERALS) to categorize the decision-making factors affecting family members' choices of LTC facilities. RESULTS: The results showed that when making decisions about the placement of family members, spouses chose facilities according to their own life experiences, children considered medical treatment convenience, grandchildren preferred to collect relevant information on facilities, and other relatives preferred to decide based on introductions from government departments. CONCLUSIONS: These results help clarify how different family roles affect decision-making processes regarding the choice of LTC facilities. In particular, spouses and female relatives require an interventional service mechanism that provides consultation or referral information.

Stereotactic body radiation therapy via helical tomotherapy to replace brachytherapy for brachytherapy-unsuitable cervical cancer patients - a preliminary result.

AIM: To review the experience and to evaluate the results of stereotactic body radiation therapy (SBRT) via helical tomotherapy (HT), for the treatment of brachytherapy-unsuitable cervical cancer. METHODS: Between September 1, 2008 to January 31, 2012, nine cervical cancer patients unsuitable for brachytherapy were enrolled. All of the patients received definitive whole pelvic radiotherapy with or without chemotherapy, followed by SBRT via HT. RESULTS: The actuarial locoregional control rate at 3 years was 78%. The mean biological equivalent dose in 2-Gy fractions of the tumor, rectum, bladder, and intestines was 76.0 ± 7.3, 73.8 ± 13.2, 70.5 ± 10.0, and 43.1 ± 7.1, respectively. Only two had residual tumors after treatment, and the others were tumor-free. Two patients experienced grade 3 acute toxicity: one had diarrhea; and another experienced thrombocytopenia. There were no grade 3 or 4 subacute toxicities. Three patients suffered from manageable rectal bleeding in months 11, 14, and 25, respectively. One stage I VA patient experienced fistula formation in month 3. CONCLUSION: SBRT via HT provides the possibility for treatment of locally advanced cervical cancer in patients who are unsuitable for brachytherapy. Long-term follow up and enrollment of more such patients to receive SBRT via the HT technique are warranted.

Exploration of long-term care institution managers' perceptions of institutional indoor environment quality and ease of administration.

This study investigated the level of management's perception of the importance of indoor environment indicators at long-term care facilities as well as the differences between the level of perceived importance and the level of implementation. This study also analyzed the indicators for improving indoor environments. This study selected Taiwanese long-term care facility managers as its subjects to whom questionnaires were distributed by mail Descriptive statistics, a one-way analysis of variance (ANOVA), and an importance-performance analysis were used to conduct analyses on the data retrieved from the questionnaires. The results indicate that, of the indoor environment indicators of four facility spaces, bedrooms had the highest perceived level of importance. The lounge was the easiest space in which to implement the indicators. Differences were found between the perceived level of importance and the level of implementation for six of the indoor environment indicators of the four facility spaces. In these four spaces, the ventilation indicator was the most important, whereas implementing the temperature and humidity indicators was the most difficult. The highest priority for indicator improvement was given to the temperature in the bedrooms and bathrooms, whereas control over temperature, humidity, and sound had a low priority. The indicators seen as requiring continuous maintenance were lighting and ventilation. Facility managers had a high level of awareness and competence in implementing the ventilation indicator. However, although they were aware of the importance of the temperature, humidity, and sound indicators, their implementation was difficult, suggesting that they needed to be improved.

Helical tomotherapy provides efficacy similar to that of intensity-modulated radiation therapy with dosimetric benefits for endometrial carcinoma.

BACKGROUND: The purpose of this study was to compare the efficacy of intensity-modulated radiotherapy (IMRT) and helical tomotherapy for endometrial cancer. METHODS: Between November 1, 2006 and November 31, 2010, 31 patients with histologically confirmed endometrial cancer were enrolled. All enrolled patients received total abdominal hysterectomy and bilateral salpingo-oophorectomy with adjuvant whole pelvic IMRT or helical tomotherapy. RESULTS: The actuarial 3-year overall survival, disease-free survival, locoregional control, and distant metastasis-free rates for the IMRT and helical tomotherapy groups were 87.5% versus 100%, 91.7% versus 51.7%, 91.7% versus 83.3%, and 91.7% versus 51.7%, respectively. The conformal index and uniformity index for IMRT versus helical tomotherapy was 1.25 versus 1.17 (P = 0.04) and 1.08 versus 1.05 (P < 0.01), respectively. Two of 31 patients with cervical stump failure were noted, one in the IMRT group and the other in the helical tomotherapy group. No acute or late grade 3 or 4 toxicities were noted, including proctitis, or genitourinary or gastrointestinal disturbances. CONCLUSION: Helical tomotherapy is as effective as IMRT and has better uniformity and conformal indices, and critical organ-sparing properties. Prospective clinical trials are needed to evaluate the comparative efficacy of IMRT versus helical tomotherapy.
