RESUMEN
BACKGROUND: Advance care planning is a process of discussion that enables competent adults to express their wishes about end-of-life care through periods of decisional incapacity. Although a number of studies have documented social workers' attitudes toward, knowledge about, and involvement in advance care planning, the information is fragmented. The purpose of this review was to provide a narrative synthesis of evidence on social workers' perspectives and experiences regarding implementation of advance care planning. METHODS: Six databases were searched for peer-reviewed research papers from their respective inception through December 2016. All of the resulting studies relevant to both advance care planning and social worker were examined. The findings of relevant studies were synthesized thematically. RESULTS: Thirty-one articles met the eligibility criteria. Six research themes were identified: social workers' attitudes toward advance care planning; social workers' knowledge, education and training regarding advance care planning; social workers' involvement in advance care planning; social workers' perceptions of their roles; ethical issues relevant to advance care planning; and the effect of social work intervention on advance care planning engagement. The findings suggest that there is a consensus among social workers that advance care planning is their duty and responsibility and that social workers play an important role in promoting and implementing advance care planning through an array of activities. CONCLUSIONS: This study provides useful knowledge for implementing advance care planning through illustrating social workers' perspectives and experiences. Further studies are warranted to understand the complexity inherent in social workers' involvement in advance care planning for different life-limiting illnesses or within different socio-cultural contexts.

BACKGROUND: Life review interventions have been used to alleviate psycho-spiritual distress in people near the end of life. However, their effectiveness remains inconclusive. AIM: To evaluate the effects of therapeutic life review on spiritual well-being, psychological distress, and quality of life in patients with terminal or advanced cancer. DESIGN: A systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. DATA SOURCES: Five databases were searched from their respective inception through February 2017 for relevant randomized controlled trials. The effects of therapeutic life review were pooled across the trials. Standardized mean differences were calculated for the pooled effects. Heterogeneity was assessed using the I2 test. Study quality was assessed using the Cochrane criteria. RESULTS: Eight randomized controlled trials met the inclusion criteria. The pooled results suggested a desirable effect of therapeutic life review on the meaning of life domain of spiritual well-being (standardized mean difference = 0.33; 95% confidence interval, 0.12 to 0.53), general distress (standardized mean difference = -0.32; 95% confidence interval, -0.55 to -0.09), and overall quality of life (standardized mean difference = 0.35; 95% confidence interval, 0.15 to 0.56) when compared to usual care only. Of the three outcomes examined, only the pooled effect on overall quality of life remained statistically significant at follow-ups up to 3 months after the intervention (standardized mean difference = 0.82; 95% confidence interval, 0.47 to 1.18). CONCLUSIONS: Therapeutic life review is potentially beneficial for people near the end of life. However, the results should be interpreted with caution due to the limited number of randomized controlled trials and associated methodological weaknesses. Further rigorously designed randomized controlled trials are warranted.

STUDY DESIGN: Retrospective study. OBJECTIVES: This study is to measure and analyze the changes of three-dimensional (3D) distances of spinal column and spinal canal at the three-column osteotomy sites and address their clinical and neurologic significance. SUMMARY OF BACKGROUND DATA: Three-column osteotomies were developed to treat severe and stiff spine deformities with insufficient understanding on the safe limit of spine shortening and the relationship between the shortening distance of the spinal column and that of the spinal canal. METHODS: Records of 52 continuous patients with severe and stiff scoliosis treated with three-column spine osteotomies at our institution from July 2013 to June 2015 were reviewed. The preoperative spinal cord function classification were type A in 31 cases, type B in 10 cases, and type C in 11 cases. The types of osteotomies carried out were extended pedicle subtraction osteotomy in nine patients and posterior vertebral column resection in 43 patients. Multimodality neuromonitoring strategies were adopted intraoperatively. 3D pre- and postoperative spine models were reconstructed from the computed tomography (CT) scans. The distances of convex and concave spinal column and the spinal canal shortening were measured and analyzed. RESULTS: The spinal column shortening distance (SCSD) measured on the 3D models (27.8âmm) were statistically shorter than those measured intraoperatively (32.8âmm) (Pâ<â0.05); however, they were strongly correlated statistically (râ=â0.82). The central spinal canal shortening distance (CCSD) was significantly shorter than the convex SCSD (Pâ<â0.05). The convex SCSD and CCSD were significantly shorter in cases with anterior column strut graft than in those with bone-on-bone fusion (Pâ<â0.05). CONCLUSION: The shortening distance of the convex spinal column cannot represent that of the central spinal canal in patients with severe scoliosis. The spinal column shortening procedure in appropriately selected patient groups with bone-on-bone fusion is a viable option with the CCSD being significantly shorter than the convex SCSD. LEVEL OF EVIDENCE: 4.

OBJECTIVE: To assess the cumulative evidence on the efficacy and effectiveness of Ginkgo biloba extract (GbE) in the treatment of dementia. DESIGN: Overview of systematic reviews. METHODS: PubMed/MEDLINE, EMBASE, Cochrane, and Google Scholar were searched in June 2016. Systematic reviews (SRs) of randomized controlled trials (RCTs) evaluating the effects of GbE on different outcomes in people with dementia or cognitive impairment were included. Methodological quality of the included SRs was assessed using the AMSTAR tool. The quality of evidence of the primary studies was assessed using GRADE. RESULTS: Twelve SRs with meta-analyses met the eligibility criteria. The quality of the evidence reported in these SRs varies ranging from low to moderate level. Overall, the available evidence suggests that GbE has potentially beneficial effects over placebo on cognitive performance, activities of daily living, and clinical global impression in the treatment of dementia at doses greater than 200mg/day (usually 240mg/day) administrated for 22 weeks or longer, and that GbE appears to be safe for human consumption. No sufficient evidence supports the favorable effects of GbE administrated for less than 22 weeks. The available evidence consistently indicates that a dose less than 200mg/day of GbE may not be adequate to yield clinical relevant effects in the treatment of dementia. CONCLUSIONS: GbE has potentially beneficial effects for people with dementia when it is administered at doses greater than 200mg/day for at least 5 months. Given the lower quality of the evidence, further rigorously-designed, multicenter-based, large-scale RCTs are warranted.

OBJECTIVE: This study examined the time trends and age distribution patterns of estimated road traffic fatalities (RTFs) in China over the period 2002-2012. METHODS: Data on age-, sex-, and region-specific RTF rates were provided by the Chinese Ministry of Health. The crude rates were standardized and the Mann-Kendall test was used to test the significance of time trends. Annual number of RTFs was calculated. To minimize the effect of yearly variations, magnitude of changes in and age distribution patterns of the RTFs were examined using mean values of 2 years. RESULTS: RTFs increased significantly in China during the study period. Several features were identified for the RTFs in China. First, RTF rates skyrocketed in rural areas including towns and counties. Second, a significant increase in RTFs was also observed in cities even though the change in RTF rates was not statistically significant there. Third, individuals aged 20-24, 40-49, and 55-64, especially in rural areas, were particularly at risk for RTFs in recent years. Finally, RTFs became more common among middle-aged and older adults than young Chinese, with roughly 57% of all RTFs occurring among individuals aged 45 and above during 2011-2012. CONCLUSIONS: RTFs increased dramatically in China during the past decade, especially in rural areas. Age distribution patterns of RTFs have changed there. Community-based public health education and intervention programs are warranted.

BACKGROUND: In this study, we aimed to establish the rabbit VX2 limb tumor model, and then prepare a "necrotic zone" as a safe margin by volumetric modulated arc therapy and simultaneous integrated boost (VMAT-SIB) technique applied in the areas where the tumor is located adjacent to the bone (GTVboost area). MATERIAL AND METHODS: Rabbits in the control group (n=10) were not treated, while those in the test group (n=10) were treated with the SIB schedule delivering a dose of 40Gy, 35Gy, 30Gy, and 25Gy to the GTVboost, GTV (gross tumor volume), CTV (clinical target volume), and PTV (planning target volume) in 10 fractions. Magnetic resonance diffusion-weighted imaging (MRDWI), 3-dimensional power Doppler angiography (3D-PDA), and histological changes were observed after radiotherapy. RESULTS: After radiotherapy, the two groups showed a significant difference in the GTVboost area. In the test group, the tumor necrosis showed a significantly low signal in DWI and high signal in apparent diffusion coefficient (ADC) maps. The 3D-PDA observation showed that tumor vascular structures decreased significantly. Histological analysis demonstrated that a necrotic zone could be generated in the GTVboost area, and microscopic examination observed cell necrosis and fibroplasia. CONCLUSIONS: This studies demonstrated the feasibility of using VMAT-SIB technique in the rabbit VX2 limb tumor model. The formation of a necrotic zone can be effectively defined as safe margin in the GTVboost area. showing potential clinical applicability.

OBJECTIVE: This systematic review aimed to examine end-of-life (EoL) care research undertaken in an Eastern cultural context--Hong Kong--with the hope of better informing EoL care professionals and policy makers and providing lessons for other countries or areas that share similar EoL care challenges. METHOD: Eight databases were searched from their respective inception through to August of 2014. All of the resulting studies conducted in Hong Kong and relevant to EoL care or palliative care were examined. The included studies were assessed with respect to study design, care settings, participants, research themes, and major findings. RESULTS: Some 107 publications published between 1991 and 2014 were identified. These studies were undertaken at a range of places by different professionals. Of the total, 44 were led by physicians, 36 by nurses, 17 by social workers, and 10 by other professionals. Participants included both inpatients and outpatients with different illnesses, nursing home residents, older community-dwelling adults, deceased individuals, care staff, and informal caregivers. A total of 13 research themes were identified: (1) attitudes to or perceptions of death and dying; (2) utilization of healthcare services, (3) physical symptoms or medical problems; (4) death anxiety or mental health issues; (5) quality of life; (6) advance directives or advance care planning; (7) supportive care needs, (8) decision making; (9) spirituality; (10) cost-effectiveness or utility studies; (11) care professionals' education and training; (12) informal caregivers' perceptions and experience; and (13) scale development or validation. SIGNIFICANCE OF RESULTS: While there has been a wide and diverse range of research activities in Hong Kong, EoL care services at primary care settings should be strengthened. Some priority areas for further research are recommended.

This study examined the time trend and pattern of HIV/AIDS-related deaths in China. Data on HIV deaths and AIDS deaths were provided by the Chinese Ministry of Health. Time trend of the overall death rates over the period 2000-2012 was examined using Poisson regression models. Pattern of AIDS deaths was examined for the period 2006-2012, using the age-, gender-, and region-specific death rates. The results indicated that HIV/AIDS-related death rate increased significantly in China over the past decade, with an average annual percentage change of 22.3%. A vast majority of the deaths occurred among those aged between 20 and 65 years, with two age peaks. The death rate was higher for males than females and in rural areas than urban areas. A total of 83% of the deaths occurred among rural residents and 67% among males. The upward trend and distribution pattern of HIV/AIDS-related deaths depicted in the present study not only provides valuable information for additional understanding of the dynamics of the HIV/AIDS epidemic in China, but also has implications for evidence-based public health intervention strategies and policies as well as for further studies.

This study investigated the associations between personality traits, based on the Big Five model, and addictive behaviors to different online activities among adolescents. A sample of 920 participants was recruited from four secondary schools in different districts using random cluster sampling. A structured questionnaire, including demographic information, internet usage pattern, the Internet Addiction Test, the Game Addiction Scale, the Bergen Facebook Addiction Scale - Revised, and the Big Five Inventory, was administered to each participant. The results demonstrated a significant difference in personality traits for addictive behaviors related to different online activities. Specifically, higher neuroticism (ß=0.15, p<0.001) and less conscientiousness (ß=0.12, p<0.001) displayed significant associations with internet addiction in general; less conscientiousness (ß=0.09, p<0.01) and low openness (ß=0.06, p<0.05) were significantly associated with gaming addiction; and neuroticism (ß=0.15, p<0.001) and extraversion (ß=0.10, p<0.01) were significantly associated with social networking addiction. Our findings may provide a better understanding of the etiopathology of internet-related addictive behaviors and have implications for psychoeducation and psychotherapy programs.

This pilot study investigated the patterns of video and internet gaming habits and the prevalence and correlates of gaming addiction in Hong Kong adolescents. A total of 503 students were recruited from two secondary schools. Addictive behaviors of video and internet gaming were assessed using the Game Addiction Scale. Risk factors for gaming addiction were examined using logistical regression. An overwhelming majority of the subjects (94%) reported using video or internet games, with one in six (15.6%) identified as having a gaming addiction. The risk for gaming addiction was significantly higher among boys, those with poor academic performance, and those who preferred multiplayer online games. Gaming addiction was significantly associated with the average time spent gaming per week, frequency of spending money on gaming, period of spending money on gaming, perceived family disharmony, and having more close friends. These results suggest that effective educational and preventative programs or strategies are needed.

The current study assessed the estimated rate of depression and associated risk factors among survivors 8 months after the 2008 Wenchuan earthquake in China. A stratified random sample of 1514 participants was recruited from all temporary camp communities in a county town 45 km away from the epicenter. The estimated rate of depression was 35.7%. The severity of depressive symptoms was significantly associated with female sex, perceived livelihood security, loss of a family member, residential house damage or collapse, and not living in an urban area, whereas married status is a protector against depressive symptoms. The results suggest that community-based effective, sustainable, and culturally sensitive interventions and services are warranted and should be directed to the groups at high risk for mental health problems.

BACKGROUND: An increasing number of studies have documented the effectiveness of qigong exercise in helping people reduce psychological stress and anxiety, but there is a scarcity of systematic reviews evaluating evidence from randomized controlled trials (RCTs) conducted among healthy subjects. METHODS: Thirteen databases were searched for RCTs from their inception through June 2013. Effects of qigong exercise were pooled across trials. Standardized mean differences (SMDs) were calculated for the pooled effects. Heterogeneity was assessed using the I2 test. The risk of bias was assessed using the Cochrane criteria. RESULTS: Seven RCTs met the inclusion criteria. Two RCTs suggested that qigong exercise immediately relieved anxiety among healthy adults, compared to lecture attendance and structured movements only. Four RCTs suggested qigong exercise relieved anxiety (pooled SMD = -0.75; 95% CI, -1.11 to -0.40), and three RCTs suggested that qigong exercise reduced stress (pooled SMD = -0.88; 95% CI, -1.22 to -0.55) among healthy subjects following one to three months of qigong practice, compared to wait-list controls. CONCLUSIONS: The available evidence suggests that qigong exercise reduces stress and anxiety in healthy adults. However, given the limited number of RCTs and their methodological flaws, further rigorously designed RCTs are needed.

PURPOSES: The aims of this study were: (1) to present the time trend of suicide rate among people aged 15 or above in China over the period 2002-2011 and (2) to examine the current profile of completed suicides during 2009-2011. METHODS: Data on suicide rate in 2002-2011 were provided by the Chinese Ministry of Health (MOH). The trends of region-, gender-, and age-specific suicide rates were examined using Poisson regression models. The mean number of completed suicides for each cohort during 2009-2011 was calculated and a mean national suicide rate was estimated. FINDINGS: The overall suicide rate decreased significantly over the past decade, but rates in young males and rural older adults did not reduce and in fact increased among older adults in both urban and rural areas towards the end of the study period. For 2009-2011, 44 % of all suicides occurred among those aged 65 or above and 79 % among rural residents. The estimated mean national suicide rate was 9.8 per 100,000 and was slightly higher for males than females. CONCLUSION: The benefits of economic growth, such as higher employment and more educational opportunities for the rural population in particular, may have contributed to the reduced suicide rate in China. However, the recent rapid changes in socioeconomic conditions could have increased stress levels and resulted in more suicides, especially among the elderly. Despite the significant reduction reported here, the latest figures suggest the declining trend is reversing. It will be important to continue monitoring the situation and to examine how urbanization and economic changes affect the well-being of 1.3 billion Chinese.

Objectives. To evaluate the effectiveness of Baduanjin Qigong exercise on sleep, fatigue, anxiety, and depressive symptoms in chronic fatigue syndrome- (CFS-) like illness and to determine the dose-response relationship. Methods. One hundred fifty participants with CFS-like illness (mean age = 39.0, SD = 7.9) were randomly assigned to Qigong and waitlist. Sixteen 1.5-hour Qigong lessons were arranged over 9 consecutive weeks. Pittsburgh Sleep Quality Index (PSQI), Chalder Fatigue Scale (ChFS), and Hospital Anxiety and Depression Scale (HADS) were assessed at baseline, immediate posttreatment, and 3-month posttreatment. The amount of Qigong self-practice was assessed by self-report. Results. Repeated measures analyses of covariance showed a marginally nonsignificant (P = 0.064) group by time interaction in the PSQI total score, but it was significant for the "subjective sleep quality" and "sleep latency" items, favoring Qigong exercise. Improvement in "subjective sleep quality" was maintained at 3-month posttreatment. Significant group by time interaction was also detected for the ChFS and HADS anxiety and depression scores. The number of Qigong lessons attended and the amount of Qigong self-practice were significantly associated with sleep, fatigue, anxiety, and depressive symptom improvement. Conclusion. Baduanjin Qigong was an efficacious and acceptable treatment for sleep disturbance in CFS-like illness. This trial is registered with Hong Kong Clinical Trial Register: HKCTR-1380.
RESUMEN
Background. Anxiety/depressive symptoms are common in patients with chronic fatigue syndrome- (CFS-) like illness. Qigong as a modality of complementary and alternative therapy has been increasingly applied by patients with chronic illnesses, but little is known about the effect of Qigong on anxiety/depressive symptoms of the patients with CFS-like illness. Purpose. To investigate the effects of Qigong on fatigue, anxiety, and depressive symptoms in patients with CFS-illness. Methods. One hundred and thirty-seven participants who met the diagnostic criteria for CFS-like illness were randomly assigned to either an intervention group or a waitlist control group. Participants in the intervention group received 10 sessions of Qigong training twice a week for 5 consecutive weeks, followed by home-based practice for 12 weeks. Fatigue, anxiety, and depressive symptoms were assessed at baseline and postintervention. Results. Total fatigue score [F(1,135) = 13.888, P < 0.001], physical fatigue score [F(1,135) = 20.852, P < 0.001] and depression score [F(1,135) = 9.918, P = 0.002] were significantly improved and mental fatigue score [F(1,135) = 3.902, P = 0.050] was marginally significantly improved in the Qigong group compared to controls. The anxiety score was not significantly improved in the Qigong group. Conclusion. Qigong may not only reduce the fatigue symptoms, but also has antidepressive effect for patients with CFS-like illness. Trial registration HKCTR-1200.
RESUMEN
AIMS: The goal of this paper was to systematically review evidence on (1) the potential magnitude of the psychopathological impacts of community-wide disasters on child and adolescent survivors, and (2) the long-term course or trajectory of disaster-induced psychopathology among children and adolescents. METHODS: The PubMed/MEDLINE and PsycINFO databases were searched from their respective inception through December 2011. All of the resulting epidemiological studies of child and adolescent survivors following community-wide disasters were examined. RESULTS: Sixty cross-sectional studies and 25 longitudinal or long-term follow-up studies were identified. The estimated rates of posttraumatic stress disorder (PTSD) and depression among child and adolescent survivors varied greatly across the included studies, ranging from 1.0 to 95 % and 1.6 to 81 %, respectively, while the reported rates of diagnosable PTSD according to the DSM-IV criteria and diagnosable depression ranged from 1.0 to 60 % and 1.6 to 33 %, respectively. The long-term courses of psychopathology among youthful survivors were summarized. Methodological issues with those studies were discussed. CONCLUSIONS: The empirical findings summarized in this review highlight the importance of psychosocial intervention at early postdisaster stages for child and adolescent survivors. The methodological flaws revealed by this review indicate the need for continued attempts to better understand the epidemiology and trajectory of psychopathological problems among youthful survivors.

Objective. To evaluate clinical trial evidence of the effectiveness of qigong exercise on depressive and anxiety symptoms. Methods. Thirteen databases were searched from their respective inception through December 2012. Relevant randomized controlled trials (RCTs) were included. Effects of qigong across trials were pooled. Standardized mean differences (SMDs) were calculated for the pooled effects. Heterogeneity was assessed using the I (2) test. Study quality was evaluated using the Wayne Checklist. Results. Twelve RCTs met the inclusion criteria. The results of meta-analyses suggested a beneficial effect of qigong exercise on depressive symptoms when compared to waiting-list controls or usual care only (SMD = -0.75; 95% CI, -1.44 to -0.06), group newspaper reading (SMD = -1.24; 95% CI, -1.64 to -0.84), and walking or conventional exercise (SMD = -0.52; 95% CI, -0.85 to -0.19), which might be comparable to that of cognitive-behavioral therapy (P = 0.54). Available evidence did not suggest a beneficial effect of qigong exercise on anxiety symptoms. Conclusion. Qigong may be potentially beneficial for management of depressive symptoms, but the results should be interpreted with caution due to the limited number of RCTs and associated methodological weaknesses. Further rigorously designed RCTs are warranted.

PURPOSE: The aim of this review is to summarize and assess critically clinical trial evidence of the effect of t'ai chi (TC) exercise on immunity and TC efficacy for treating infectious diseases. METHODS: Fourteen databases were searched from their respective inceptions through January 2011. No language restrictions were imposed. Quality and validity of the included clinical trials were evaluated using standard scales. RESULTS: Sixteen (16) studies, including 7 randomized controlled trials, 4 controlled clinical trials, and 5 retrospective case-control studies, met the inclusion criteria for this review. One (1) study examined clinical symptoms, 3 studies tested functional measures of immunity (antigen-induced immunity), and the other studies tested enumerative parameters of immunity. such as lymphocytes, immunoglobulins, complements, natural-killer cells, and myeloid dendritic cells. Overall, these studies suggested favorable effects of TC exercise. CONCLUSIONS: TC exercise appears to improve both cell-mediated immunity and antibody response in immune system, but it remains debatable whether or not the changes in immune parameters are sufficient to provide protection from infections.

The objective of this review was to summarize and critically evaluate the clinical evidence of the effect of qigong exercise on immunity and its efficacy in the prevention or treatment of infectious diseases. Thirteen databases were searched from their respective inceptions through January 2011, and all controlled clinical trials of qigong exercise on immunity and infections were included. Quality and validity of the included studies were evaluated using standard scales. Seven studies including two randomized controlled trials (RCTs), two controlled clinical trials (CCTs) and three retrospective observational studies (ROSs) met the inclusion criteria. One study focused on functional measures of immunity (antigen-induced immunity) and six studies on enumerative parameters of immunity. No study on clinical symptoms relevant to infectious diseases could be identified. Overall, the included studies suggested favorable effects of qigong exercise on immunity, but the quality of research for most of the studies examined in this review was poor. Further rigorously designed studies are required, which should adhere to accepted standards of methodology for clinical trials.
