Assessing family function: older adults vs. care nurses: a cross-sectional comparative study.

BACKGROUND: This study aimed to assess family function in home care for older adults. Understanding family dynamics is essential for providing quality care to older adults choosing to age in place. METHODS: In a cross-sectional study, 53 patients aged 65 or older receiving home care were evaluated, along with four home care nurses. The General Function of Family Assessment Device (FAD-GF) was used for self-assessment to examine family resources. RESULTS: Only 5.7% of older adults reported good family function. Strong correlations were found between assessments by nurses and older adults. Among the six aspects of family function, "problem solving," "communication," "affective responsiveness," and the overall results showed no disparities between the evaluations of older adults and nurses. CONCLUSIONS: Home care nurses can effectively assess family function using the FAD-GF, particularly after six months of care. This assessment can help identify family issues and enhance home care quality through nurse training in FAD-GF application.

Effects of social capital on healthcare utilization among older adults in Indonesia.

Social capital potentially affects older adults' access to healthcare services. However, the effects of social capital on the use of various types of healthcare services using longitudinal data have yet to be explored. This study aimed to examine the effects of structural and cognitive social capital on different types of healthcare utilization by older adults in Indonesia. Data were from the Indonesian Family Life Survey (waves 4 and 5) in 2007 and 2014. The sample consisted of participants aged 60 years and older who completed both waves (n = 1374). Healthcare utilization by older adults assessed health posts (posyandu), health checkups, outpatient care and hospital admissions. Social capital consisted of neighborhood trust and community participation. Generalized estimating equation models were used for the analysis. Older adults with high community participation had a higher likelihood of using preventive care in posyandu (OR = 5.848, 95% CI = 2.585-13.232) and health checkup visits (OR = 1.621, 95% CI = 1.116-2.356). Meanwhile, neighborhood trust was related to a higher probability of hospital admissions (OR = 1.255, 95% CI = 1.046-1.505). Social capital significantly affects older adults' preventive and treatment healthcare utilization. Maximizing the availability of social participation and removing barriers to access to preventive and medical care in an age-friendly environment are suggested.

Relationship between indwelling site and peripheral venous catheter-related complications in adult hospitalized patients: A systematic review and meta-analysis.

AIMS AND OBJECTIVES: This systematic review and meta-analysis aimed to compare the incidence of PVC-related complications between catheterisation in the forearm and back of the hand in adult patients. BACKGROUND: A peripheral intravenous catheter (PVC) is often inserted as part of care during patients' hospitalisation. The catheter is typically inserted in the forearm or at the back of the hand in usual practice. Studies have not yet reached a consensus on the optimal insertion site in any clinical setting. DESIGN: We performed a systematic review and meta-analysis based on PRISMA guidelines. METHODS: We searched the following electronic databases: PubMed, Cochrane Library, Embase, and CINAHL. Randomised controlled trials, cohort studies, case-control studies and cross-sectional studies from inception to July 2021 reporting the incidence of PVC-related complications at the forearm and back of the hand were included. Fixed-effects models and random-effects models were used to derive the pooled risk ratios. RESULTS: Twenty-four studies involving 16562 PVCs met our inclusion criteria. The meta-analysis showed that compared with PVC placement in the back of the hand, placement in the forearm was associated with a higher incidence of total complications and infiltration/extravasation. However, the differences between the PVC indwelling sites were not significant (total complications: P = 0.43; phlebitis: P = 0.35; infiltration/extravasation: P = 0.51). Both incidence of total complications and infiltration/extravasation analyses showed high heterogeneity (total complications: I2  = 60%; infiltration/extravasation: I2  = 58%). CONCLUSION: Available evidence suggests that there is no significant difference between PVC placement in the forearm and at the back of the hand in terms of the incidence of complications, thus making both approaches suitable. RELEVANCE TO CLINICAL PRACTICE: For patients who need indwelling PVC, medical staff can choose the best indwelling site, and both forearm and back of the hand are suitable.

Differing determinants of disability trends among men and women aged 50 years and older.

BACKGROUND: Researchers have emphasized the importance of examining how different factors affect men's and women's functional status over time. To date, the literature is unclear about whether sex affects the rate of change in disability in middle to older age. Researchers have further emphasized the importance of examining how different factors affect men's and women's functional status over time. We examined (a) sex differences in disability trends and (b) the determinants of the rate of change in disability for men and women 50 years and older. METHODS: This study utilized the Taiwan Longitudinal Study on Aging Survey, a nationally representative database (four waves of survey data 1996-2007, N = 3429). We modeled and compared the differences in disability trends and the influences of determinants on trends among men and women using multiple-indicator and multiple-group latent growth curves modeling (LGCM). Equality constraints were imposed on 10 determinants across groups. RESULTS: Once disability began, women progressed toward greater disability 18% faster than men. Greater age added about 1.2 times the burden to the rate of change in disability for women than men (p < 0.001). More comorbidities also added significantly more burden to baseline disability and rate of change in disability among women than men (p < 0.001), but women benefited more from higher education levels in lower baseline disability and slower rate of change. Having a better social network was associated with lower baseline disability among women only (p < 0.05). For both men and women, physically active leisure-time activities were beneficial in lower baseline disability (p men and women < 0.001) and rate of change in disability (p men < 0.01; p women < 0.05), with no significant differences between groups. CONCLUSIONS: Age may widen the sex gap in the rate of change in disability. However, both sexes benefit from participating in leisure-time activities. Promoting health literacy improves health outcomes and physical function among women.

Porcine epidemic diarrhea virus infection induces endoplasmic reticulum stress and unfolded protein response in jejunal epithelial cells of weaned pigs.

Porcine epidemic diarrhea virus (PEDV) infection leads to diarrhea and subsequently to decreased feed efficiency and growth in weaned pigs. Given that few studies have addressed the host-virus interaction in vivo, this study focused on endoplasmic reticulum (ER) stress and unfolded protein response (UPR) in jejunal epithelial cells during PEDV infection. Eight-week-old pigs (n = 64) were orally inoculated with PEDV IN19338 strain (n = 40) or sham-inoculated (n = 24) and analyzed for PEDV viral RNA shedding using reverse transcription-quantitative polymerase chain reaction and for viral antigen within enterocytes using immunohistochemistry (IHC). ER stress was analyzed in a subset of 9 PEDV-inoculated pigs with diarrhea, detectable viral RNA, and viral antigen (PEDV-immunopositive pigs). Compared with control pigs, PEDV-immunopositive pigs had a reduced ratio of villus height to crypt depth in the jejunum (P = .002, n = 9 per group), consistent with intestinal injury. The protein levels of ATF6, IRE1, PERK, XBP1u, ATF4, GRP78, and caspase-3 were assessed in jejunal epithelial cells at the villus tips via IHC. Both ER stress and UPR were demonstrated in PEDV-immunopositive pigs by the increased expression of ATF6 (P = .047), IRE1 (P = .007), and ATF4 (P = .001). The expression of GRP78 (P = .024) and caspase-3 (P = .004) were also increased, indicating an accompanying increase in ER protein folding capacity and apoptosis. Overall, these results reveal that PEDV infection induces ER stress and UPR in intestinal epithelial cells of weaned pigs.

Determinants associated with medical-related long-term care service use among community-dwelling older adults in Taiwan.

INTRODUCTION: Medical-related long-term care (LTC) service use among community-dwelling older adults in Taiwan is resource-intensive, and planning is essential to promote aging-in-place. METHODS: Administrative data from 4/1/2017 to 11/26/2019 among more than 14,000 residents were analyzed with generalized estimating equations (GEEs) to identify determinants of medical-related LTC service use. RESULTS: Older adults using medical-related LTC services tended to be younger (79.9 vs. 80.7; p<.0001), male (42.7% vs. 38.5%; p<.0001), multi-morbid (3.1 vs. 2.5; p<.0001), and higher mean activities of daily living (ADL) disability (8.2 vs. 4.2; p<.0001), instrumental ADL (IADL) disability (11.0 vs. 9.1; p<.0001), and hospitalizations (1.1 vs. 0.4; p<.0001). Significant determinants of medical-related LTC services include age, education, stroke, coronary heart disease, diabetes, vision impairment, ADL disability, and prior hospitalization. DISCUSSION: The success of LTC 2.0 will depend on ADL support and care coordination to manage chronic conditions such as diabetes, vision impairment, coronary heart disease, and stroke.

[Berberine hydrochloride inhibits benign prostatic hyperplasia in rats by activating the Nrf2/ARE pathway].

Objective: To study the inhibitory effect of berberine hydrochloride (BBR) on BPH and its underlying mechanism in male rats. METHODS: Forty male rats were randomly divided into a normal control, a BPH model control, a BBR intervention, and a BBR+Bruceol intervention group, and the BPH model was established in the latter three groups. The animals in the normal and BPH model control groups were treated intragastrically with normal saline, and those in the BBR and BBR+Bruceol intervention groups with BBR at 200 mg/kg and BBR plus Bruceol at 1 mg/kg, respectively, once a day for 14 consecutive days. The prostates of the rats were harvested for measurement of their wet weight and prostatic index, detection of the contents of superoxide dismutase (SOD) and malondialdehyde (MDA) and determination of the protein expressions of nuclear factor E2-related factor 2 (Nrf2), antioxidant response element (ARE) and reduced coenzyme I quinone oxidoreductase (NQO1) in the prostate tissue by Western blot. RESULTS: The wet weights of the prostate in the normal control, BPH model control, BBR intervention, and BBR+Bruceol intervention groups were (715.63 ± 28.57) mg, (1118.93 ± 36.41) mg, (896.21 ± 20.24) mg and (967.23 ± 24.98) mg, the prostate indexes were 2.10 ± 0.13, 3.45 ± 0.22, 2.75 ± 0.19 and 3.01 ± 0.14, the SOD contents in the prostate tissue were (38.54 ± 5.12) U/mg, (13.98 ± 2.01) U/mg, (26.75 ± 3.19) U/mg and (20.16 ± 4.10) U/mg, and the MDA contents were (3.59 ± 0.83) nmol/mg, (12.63 ± 3.26) nmol/mg, (7.20 ± 1.69) nmol/mg and (9.85 ± 1.71) nmol/mg, respectively. The relative expressions of the Nrf2 protein in the four groups were 0.53 ± 0.06, 0.12 ± 0.03, 0.36 ± 0.04 and 0.25 ± 0.03, those of the ARE protein were 0.69 ± 0.07, 0.21 ± 0.02, 0.50 ± 0.06 and 0.30 ± 0.04, and those of the NQO1 protein were 0.44 ± 0.05, 0.15 ± 0.03, 0.30 ± 0.04 and 0.22 ± 0.03, respectively. There were statistically significant differences in all the above indicators between the normal and BPH model control groups (P < 0.05), as well as between the BPH model control and BBR intervention groups (P < 0.05) and between the BPH model control and the BBR+Bruceol intervention groups (P < 0.05). CONCLUSIONS: BBR hydrochloride can inhibit prostatic hyperplasia in BPH rats and reduce oxidative stress and pathological changes by activating the Nrf2/ARE pathway.

Preparedness for containing COVID-19 outbreak in mass religious gathering with non-pharmaceutical interventions (NPIs).

BACKGROUND: The COVID-19 outbreaks associated with mass religious gatherings which have the potential of invoking epidemics at large scale have been a great concern. This study aimed to evaluate the risk of outbreak in mass religious gathering and further to assess the preparedness of non-pharmaceutical interventions (NPIs) for preventing COVID-19 outbreak in this context. METHODS: The risk of COVID-19 outbreak in mass religious gathering was evaluated by using secondary COVID-19 cases and reproductive numbers. The preparedness of a series of NPIs for preventing COVID-19 outbreak in mass religious gathering was then assessed by using a density-dependent model. This approach was first illustrated by the Mazu Pilgrimage in Taiwan and validated by using the COVID-19 outbreak in the Shincheonji Church of Jesus (SCJ) religious gathering in South Korea. RESULTS: Through the strict implementation of 80% NPIs in the Mazu Pilgrimage, the number of secondary cases can be substantially reduced from 1508 (95% CI: 900-2176) to 294 (95% CI: 169-420) with the reproductive number (R) significantly below one (0.54, 95% CI: 0.31-0.78), indicating an effective containment of outbreak. The expected number of secondary COVID-19 cases in the SCJ gathering was estimated as 232 (basic reproductive number (R0) = 6.02) and 579 (R0 = 2.50) for the first and second outbreak, respectively, with a total expected cases (833) close to the observed data on high infection of COVID-19 cases (887, R0 = 3.00). CONCLUSION: We provided the evidence on the preparedness of NPIs for preventing COVID-19 outbreak in the context of mass religious gathering by using a density-dependent model.

Validation of the short falls efficacy scale-international for Taiwanese community-dwelling older adults: Associations with fall history, physical frailty, and quality of life.

The FES-I is widely used to measure the fear of falling. However, studies linking the Chinese version of the FES-I to frailty and quality of life among older adults are still limited. Thus, this study examined the association of the full 16-item FES-I and the 7-item short FES-I with fall history, physical frailty, and quality of life among older Taiwanese adults. A total of 751 community-dwelling older adults in Taipei City participated in this study. Data analyses included logistic and linear regression models. The 16-item and the short FES-I were strongly correlated (Spearman rho = 0.963), and both scales are reliable. The 7-item FES-I was positively associated with fall history and physical frailty and negatively associated with the physical (b = -0.65, p < 0.001) and mental (b = -0.59, p < 0.001) components of health-related quality of life, independent of physical frailty. Thus, the short FES-I can be used to increase the feasibility of health screenings of older adults in Chinese-speaking contexts.

Alterations in Intestinal Innate Mucosal Immunity of Weaned Pigs During Porcine Epidemic Diarrhea Virus Infection.

In the small intestine, localized innate mucosal immunity is critical for intestinal homeostasis. Porcine epidemic diarrhea virus (PEDV) infection induces villus injury and impairs digestive function. Moreover, the infection might comprise localized innate mucosal immunity. This study investigated specific enterocyte subtypes and innate immune components of weaned pigs during PEDV infection. Four-week-old pigs were orally inoculated with PEDV IN19338 strain (n = 40) or sham-inoculated (n = 24). At day post inoculation (DPI) 2, 4, and 6, lysozyme expression in Paneth cells, cellular density of villous and Peyer's patch microfold (M) cells, and the expression of polymeric immunoglobulin receptor (pIgR) were assessed in the jejunum and ileum by immunohistochemistry, and interleukin (IL)-1ß and tumor necrosis factor (TNF)-α were measured in the jejunum by ELISA. PEDV infection led to a decrease in the ratios of villus height to crypt depth (VH-CD) in jejunum at DPI 2, 4, and 6 and in ileum at DPI 4. The number of villous M cells was reduced in jejunum at DPI 4 and 6 and in ileum at DPI 6, while the number of Peyer's patch M cells in ileum increased at DPI 2 and then decreased at DPI 6. PEDV-infected pigs also had reduced lysozyme expression in ileal Paneth cells at DPI 2 and increased ileal pIgR expression at DPI 4. There were no significant changes in IL-1ß and TNF-α expression in PEDV-infected pigs compared to controls. In conclusion, PEDV infection affected innate mucosal immunity of weaned pigs through alterations in Paneth cells, villous and Peyer's patch M cells, and pIgR expression.

From fragmentation toward integration: a preliminary study of a new long-term care policy in a fast-aging country.

BACKGROUND: Taiwan, one of the fastest-aging countries in the world, started implementing version 1.0 of its long-term care (LTC) plan in 2008. In 2017, LTC Plan 2.0 began a new era with its goal to integrate Taiwan's fragmented LTC service system. LTC Plan 2.0 also aims to establish an integrated community-based LTC system incorporating both health care and disability prevention. This three-tier model consists of the following: two LTC services with a day-care center as their base and case management (Tier A), a day-care center and a single LTC service (Tier B), and LTC stations that provide primary prevention services and respite services for frail community-dwelling older adults to prevent further disabilities (Tier C). A defined cluster of agencies in a local area works together as a Tier ABC team. LTC Plan 2.0 is a new policy for Taiwan, and hence it is important to understand the agencies' initial difficulties with implementation and identify future challenges to help further policy development. METHODS: This preliminary study explored the challenges to implementing LTC 2.0 through in-depth interviews based on Evashwick's integration mechanisms with representatives from three service teams. We interviewed three chief executive officers and three case managers. RESULTS: We found that the LTC Plan 2.0 mechanisms for service integration have been insufficiently implemented. Recommendations include (1) Build up the trust between agencies and government, avoid duplication of LTC services within Tier ABC team, and encourage agencies within a team to create a shared administrative system with the same mission and vision. (2) Clarify the roles and responsibilities of government care managers and agency case managers. (3) Provide an integrated information system and create an official platform for sharing client records across different agencies and caregivers. (4) Establish a tool and platform to track the budget and payment across different levels of service as soon as possible. CONCLUSION: There is an increased demand for LTC services in Taiwan because of its rapidly aging population. Our findings shed some light on the challenges to developing integrated LTC services and thus may help both policymakers and service providers find ways to overcome these challenges.

Value-added strategy models to provide quality services in senior health business.

OBJECTIVE: The rapid population aging is now a global issue. The increase in the elderly population will impact the health care industry and health enterprises; various senior needs will promote the growth of the senior health industry. Most senior health studies are focused on the demand side and scarcely on supply. Our study selected quality enterprises focused on aging health and analyzed different strategies to provide excellent quality services to senior health enterprises. DESIGN: We selected 33 quality senior health enterprises in Taiwan and investigated their excellent quality services strategies by face-to-face semi-structured in-depth interviews with CEO and managers of each enterprise in 2013. SETTING: A total of 33 senior health enterprises in Taiwan. PARTICIPANTS: Overall, 65 CEOs and managers of 33 enterprises were interviewed individually. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Core values and vision, organization structure, quality services provided, strategies for quality services. RESULTS: This study's results indicated four type of value-added strategy models adopted by senior enterprises to offer quality services: (i) residential care and co-residence model, (ii) home care and living in place model, (iii) community e-business experience model and (iv) virtual and physical portable device model. The common part in these four strategy models is that the services provided are elderly centered. These models offer virtual and physical integrations, and also offer total solutions for the elderly and their caregivers. Through investigation of successful strategy models for providing quality services to seniors, we identified opportunities to develop innovative service models and successful characteristics, also policy implications were summarized. CONCLUSIONS: The observations from this study will serve as a primary evidenced base for enterprises developing their senior market and, also for promoting the value co-creation possibility through dialogue between customers and those that deliver service.

[The Status, Change and Health Issues of Inpatients' Sixth Vital Sign in a Medical Center].

BACKGROUND: Hospitalized patients generally have elevated levels of emotional distress. Gaining a better under-standing of the problem of emotional distress among hospitalized patients is conducive to providing appropriate emotional care and promoting their recovery. PURPOSE: To analyze the scores for the "sixth vital sign" (i.e., emotional distress), diversification, and the health-related problems of hospitalized patients at a medical center in Taiwan. The results may offer an important reference for providing effective emotional care to hospitalized patients. METHODS: A retrospective descriptive research design was used. Data were collected from all of the 27,885 inpatients that were registered at the target hospital in 2013. Further, a total of 245,814 attendance records were assessed to extract the data that were relevant to emotional distress. RESULTS: The findings revealed that 58.3% of hospitalized patients had earned a sixth vital sign score ≥ 1 and that 0.8% of these patients had earned a score ≥ 4. On the whole, the sixth vital sign scores of hospitalized patients were found to decrease progressively with the number of hospitalization days except for hematology and oncology, neurosurgery, and plastic surgery patients. The highest emotional distress scores were found among family medicine, dermatology, and plastic surgery patients. Moreover, emotional distress scores were significantly higher in patients who had health problems that involved pain, anxiety, or sleep disorder. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The present study suggests that improving the emotional care of hematology, oncology, neurosurgery, family medicine, dermatology, and plastic surgery patients and of patients with health problems involving pain, anxiety, or sleep disorder may significantly improve the quality of inpatient holistic healthcare. Only 0.8% of the subjects in the present study had an emotional distress score ≥ 4, which is significantly lower than the level reported in other similar studies. Our findings suggest that related education and training for nursing staffs may improve their assessment and care practices in caring for patients with emotional distress. Furthermore, using more appropriate words, methods, and environments to evaluate the emotional distress of patients holds the potential to improve assessment and care for these patients.

Trajectories of Older Adults' Leisure Time Activity and Functional Disability: a 12-Year Follow-Up.

PURPOSE: This study explored how changes in leisure time activities interplayed with changes in functional disability among Taiwanese older adults. METHOD: A parallel process and multiple-indicator latent growth curve modeling was adopted for analysis of the data. Longitudinal data from four waves of the Taiwan Longitudinal Study on Aging, collected between 1996 and 2007, were used for analysis. Data included responses of 5451 older adults with a mean age of 67.16 years (SD = 2.51) in 1996. RESULTS: Compared to baseline level of leisure time activities, increasing the rate of change in leisure time activities has more than three times the effect on slowing down the progression of functional disabilities. The baseline functional disabilities did not significantly predict the changes in leisure time activity participation. CONCLUSION: Engagement in leisure time activity in later life is associated with a slower speed of progression toward functional disability. Early functional disability may not inhibit leisure time activity participation in later life.

Co-creating value through demand and supply integration in senior industry-observations on 33 senior enterprises in Taiwan.

OBJECTIVE: With global population aging, great business opportunities are driven by the various needs that the elderly face in everyday living. Internet development makes information spread faster, also allows elderly and their caregivers to more easily access information and actively participate in value co-creation in the services. This study aims to investigate the designs of value co-creation by the supply and demand sides of the senior industry. DESIGN: This study investigated senior industry in Taiwan and analyzed bussiness models of 33 selected successful senior enterprises in 2013. We adopted series field observation, reviews of documentations, analysis of meeting records and in-depth interviews with 65 CEOs and managers. SETTING: Thirty-three quality enterprises in senior industry. PARTICIPANTS: Sixty-five CEOs and managers in 33 senior enterprises. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Value co-creation design, value co-creating process. RESULTS: We constructed a conceptual model that comprehensively describes essential aspects of value co-creation and categorized the value co-creation designs into four types applying for different business models: (i) interaction in experience spaces co-creation design, (ii) on-site interacting co-creation design, (iii) social networking platform co-creation design and (iv) empowering customers co-creation design. Through value co-creation platform design, the senior enterprises have converted the originally passive roles of the elderly and caregivers into active participants in the value co-creation process. CONCLUSIONS: The new paradigm of value co-creation designs not only promote innovative development during the interactive process, lead enterprises reveal and meet customers' needs but also increase markets and profits.

Observations on quality senior health business: success patterns and policy implications.

OBJECTIVE: Population ageing is a global issue that affects almost every country. Most ageing researches focused on demand side and studies related to supply side were relatively scarce. This study selected quality enterprises focus on ageing health and analysed their patterns on providing quality services successfully. DESIGN: Our study selected quality senior health enterprises and explored their success patterns through face-to-face semi-structured in-depth interviews with CEO of each enterprise in 2013. SETTING: Thirty-three quality senior health enterprises in Taiwan. PARTICIPANTS: Thirty-three CEO's of enterprises were interviewed individually. INTERVENTION: None. MAIN OUTCOME MEASURES: Core values and vision, historical development, organization structure, services/products provided, delivering channels, customer relationships and further development strategies. RESULTS: Our results indicated success patterns for senior enterprises that there were meeting diversified lifestyles and substitutive needs for the elderly and their caregivers, providing a total solution for actual/virtual integration and flexible one-stop shopping services. We classified these enterprises by used degree of clicks-and-mortar of services and residing situation of the elderly. Industry characteristics and policy implications were summarized. CONCLUSIONS: Our observations will serve as a primary evidenced base for enterprises developing their senior market, and also for opening dialogue between customers and enterprises to facilitate valuable opportunities for co-creation between the supply and demand sides.

Forecasting the Incidence of Dementia and Dementia-Related Outpatient Visits With Google Trends: Evidence From Taiwan.

BACKGROUND: Google Trends has demonstrated the capability to both monitor and predict epidemic outbreaks. The connection between Internet searches for dementia information and dementia incidence and dementia-related outpatient visits remains unknown. OBJECTIVE: This study aimed to determine whether Google Trends could provide insight into trends in dementia incidence and related outpatient visits in Taiwan. We investigated and validated the local search terms that would be the best predictors of new dementia cases and outpatient visits. We further evaluated the nowcasting (ie, forecasting the present) and forecasting effects of Google Trends search trends for new dementia cases and outpatient visits. The long-term goal is to develop a surveillance system to help early detection and interventions for dementia in Taiwan. METHODS: This study collected (1) dementia data from Taiwan's National Health Insurance Research Database and (2) local Internet search data from Google Trends, both from January 2009 to December 2011. We investigated and validated search terms that would be the best predictors of new dementia cases and outpatient visits. We then evaluated both the nowcasting and the forecasting effects of Google Trends search trends through cross-correlation analysis of the dementia incidence and outpatient visit data with the Google Trends data. RESULTS: The search term "dementia + Alzheimer's disease" demonstrated a 3-month lead effect for new dementia cases and a 6-month lead effect for outpatient visits (r=.503, P=.002; r=.431, P=.009, respectively). When gender was included in the analysis, the search term "dementia" showed 6-month predictive power for new female dementia cases (r=.520, P=.001), but only a nowcasting effect for male cases (r=.430, P=.009). The search term "neurology" demonstrated a 3-month leading effect for new dementia cases (r=.433, P=.008), for new male dementia cases (r=.434, P=.008), and for outpatient visits (r=.613, P<.001). CONCLUSIONS: Google Trends established a plausible relationship between search terms and new dementia cases and dementia-related outpatient visits in Taiwan. This data may allow the health care system in Taiwan to prepare for upcoming outpatient and dementia screening visits. In addition, the validated search term results can be used to provide caregivers with caregiving-related health, skills, and social welfare information by embedding dementia-related search keywords in relevant online articles.

MYC protein expression is associated with poor prognosis in diffuse large B cell lymphoma patients treated with RCHOP chemotherapy.

This study aims to investigate the prognostic significance of the MYC protein expression in diffuse large B cell lymphoma (DLBCL) patients treated with RCHOP (rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone). A total of 60 patients with DLBCL from 2008 to 2013 were included. Formalin-fixed, paraffin-embedded DLBCL samples were analyzed for MYC protein expression and divided into high or low MYC group. The MYC protein expression and the international prognostic variables were evaluated. The high MYC protein expression predicted a shorter 3-year estimated overall survival (OS) and progression-free survival (PFS) versus the low MYC protein expression (57 % vs. 96 %, P < 0.001 and 50 % vs. 96 %, P = 0.001, respectively). Multivariate analysis confirmed the prognostic significance of the MYC protein expression for both OS (HR, 11.862; 95 % CI, 1.462-96.218; P = 0.021) and PFS (HR, 6.073; 95 % CI, 1.082-34.085; P = 0.040). MYC protein expression with International Prognostic Index (IPI) score distinguished patients into three risk groups with different 3-year OS rates (χ (2) 23.079; P < 0.001) and distinct 3-year PFS rates (χ (2) 15.862; P < 0.001). This study suggests that the MYC protein expression is an important inferior prognostic factor for survival in patients with DLBCL treated with RCHOP. The combinative model with IPI score and MYC protein expression could stratify DLBCL patients into prognostically relevant subgroups more effectively than either the IPI or the MYC alone.

The impact of petrochemical industrialisation on life expectancy and per capita income in Taiwan: an 11-year longitudinal study.

BACKGROUND: Petrochemical industries have been identified as important sources of emissions of chemical substances, and adverse health outcomes have been reported for residents who live nearby. The purpose of the current study was to examine the adverse effects of petrochemical industrialization in Taiwan on the life expectancy and personal income of people living in nearby communities. METHODS: This study compared life expectancies and personal income between one industrial county (Yunlin County) and one reference county (Yilan County), which had no significant industrial activity that might emit pollutants, in Taiwan through analysis of 11 year long and publicly available data. Data from before and after the petrochemical company in the industrial county started (year 1999) operating were compared. RESULTS: Residents of the industrialized county had lesser increases in life expectancy over time than did residents of a similar but less-industrialized county, with difference means ranging from 0.89 years (p<0.05) to 1.62 years (p<0.001) at different stages. Male residents were more vulnerable to the effects of industrialization. There were no significant differences in individual income between the two counties. CONCLUSIONS: Countries, including Taiwan and the U.S., embracing petrochemical industries now face the challenge of environmental injustice. Our findings suggested that life expectancy lengthening was slowed and income growth was stalled for residents living in the industrial communities.
