Quality of Life Among Geriatric Community Members Following the Kaohsiung Gas Explosion: A 5-Year Cross-Sectional Study.

OBJECTIVE: The aim was to conduct a follow-up study of the quality of life (QoL) and to measure lifestyle factors among the aging survivors of a petrochemical gas explosion in Taiwan 5 years after the event. METHODS: A community-based survey with cross-sectional assessments was conducted with residents of a community who experienced a petrochemical gas explosion 5 years after the disaster. Short Form 12v2 (SF-12v2) was used to survey a representative sample of participants. RESULTS: The risk factors for different QoL subscales were stressors and chronic physical illness, and the protective factors were higher income and better diet and exercise habits. The elderly participants had better diet and exercise habits than the younger participants in this survey. Aging had a negative impact on the physical QoL subscales [physical functioning (PF), bodily pain (BP), general health (GH), Physical Component Summary (PCS)] but a positive impact on psychological QoL subscales [vitality (VT), social functioning (SF), emotional problems (RE), mental health (MH), Mental Health Component Summary (MCS)]. CONCLUSIONS: While participants' psychiatric status had improved after 5 years, their QoL continued to be affected, especially in those with stress and physical illness. The elderly groups maintained a relatively acceptable QoL in terms of psychological aspects. Postdisaster treatment and follow-up should be addressed to a greater degree, especially in victims with mental illness or chronic illness and those with fewer socioeconomic resources.

A Community Survey of Quality of Life and Psychiatric Disorders among Residents Following the Kaohsiung Gas Explosion: a 5-Year Cross-Sectional Follow-Up Study.

To investigate factors associated with quality of life (QoL) and disaster-related psychiatric disorders, including posttraumatic stress disorder (PTSD) and major depressive episode (MDE), in the survivors of a gas explosion in Taiwan 5 years after the event. A community-based cross-sectional study of residents from an area that experienced a gas explosion was conducted 5 years after the event. The Short Form 12v2 (SF-12v2) was used to screen 2511 participants. The Disaster-Related Psychological Screening Test (DRPST) was used to assess probable MDE and PTSD. A total of 2511 participants, including 604 males and 1907 females, completed the QoL survey. The average age was 56.02 ± 16.78 years, and most participants were in the ≧65 age group (39.7%). The males had better QoL in the physical dimensions. Lifestyle was significantly positively associated with QoL. A total of 894 participants completed the DRPST, which showed some individuals with probable MDE (n = 93, 10.4%), probable PTSD (n = 22, 2.5%), or probable MDE and PTSD (n = 49, 5.5%); most people had no MDE or PTSD (n = 730, 81.7%). Those in the probable PTSD or MDE groups were significantly more likely to be female or to be experiencing stressors (p < 0.001). The participants continued to be affected by the disaster based on their QoL, even 5 years later. Females had a higher risk of probable psychiatric disorders and poorer QoL in the physical dimensions. Long-term follow-up, interventions and investigations after a disaster are needed.

Development and Implementation of Societal Influences Survey Questionnaire (SISQ) for Peoples during COVID-19 Pandemic: A Validity and Reliability Analysis.

The emergence of Coronavirus disease 2019 (COVID-19) had rapidly spread since FEB/MAR 2020. Policy to prevent transmission of COVDI-19 resulted in multi-dimensional impact on social interaction. We aimed to develop a beneficial survey tool with favorable quality and availability, the Societal Influences Survey Questionnaire (SISQ), to evaluate social influences on people during this pandemic. The SISQ was developed with 15 items and 4-point Likert scales consisting of five factors. These include social distance, social anxiety, social desirability, social information, and social adaptation. Construct validity and reliability were performed to verify the SISQ. A total of 1912 Taiwanese were recruited. The results demonstrated that the SISQ has acceptable reliability, with Cronbach's alphas ranging between 0.57 and 0.76. The SISQ accounted for 58.86% and satisfied the requirement of Kaiser-Mayer-Olkinvalues (0.78) and significant Bartlett's Test of sphericity. Moreover, the confirmatory factor analysis fit indices also indicated the adequacy of the model. As for multiple comparison, females scored higher than males in factor of social distance. Unemployed participants and those without partners scored higher in several domains of factors. The survey method and survey instrument prove reliable and valuable, also providing different categories of assessment results regarding social influences and their impacts. Further studies are warranted to extend the applicability of SISQ.

Ag-plasma modification enhances bone apposition around titanium dental implants: an animal study in Labrador dogs.

Dental implants with proper antibacterial ability as well as ideal osseointegration are being actively pursued. The antimicrobial ability of titanium implants can be significantly enhanced via modification with silver nanoparticles (Ag NPs). However, the high mobility of Ag NPs results in their potential cytotoxicity. The silver plasma immersion ion-implantation (Ag-PIII) technique may remedy the defect. Accordingly, Ag-PIII technique was employed in this study in an attempt to reduce the mobility of Ag NPs and enhance osseointegration of sandblasted and acid-etched (SLA) dental implants. Briefly, 48 dental implants, divided equally into one control and three test groups (further treated by Ag-PIII technique with three different implantation parameters), were inserted in the mandibles of six Labrador dogs. Scanning electron microscopy, X-ray photoelectron spectroscopy, and inductively coupled plasma optical emission spectrometry were used to investigate the surface topography, chemical states, and silver release of SLA- and Ag-PIII-treated titanium dental implants. The implant stability quotient examination, Microcomputed tomography evaluation, histological observations, and histomorphometric analysis were performed to assess the osseointegration effect in vivo. The results demonstrated that normal soft tissue healing around dental implants was observed in all the groups, whereas the implant stability quotient values in Ag-PIII groups were higher than that in the SLA group. In addition, all the Ag-PIII groups, compared to the SLA-group, exhibited enhanced new bone formation, bone mineral density, and trabecular pattern. With regard to osteogenic indicators, the implants treated with Ag-PIII for 30 minutes and 60 minutes, with the diameter of the Ag NPs ranging from 5-25 nm, were better than those treated with Ag-PIII for 90 minutes, with the Ag NPs diameter out of that range. These results suggest that Ag-PIII technique can reduce the mobility of Ag NPs and enhance the osseointegration of SLA surfaces and have the potential for future use.

Disaster Psychiatry in Taiwan: A Comprehensive Review.

Natural disasters have caused millions of deaths worldwide, and hundreds of millions of people have suffered from various types of physical or mental traumas. Disasters change patterns of thinking and the concept of security among members of a community, which highlights the importance of mental rehabilitation in disaster psychiatry. Mental rehabilitation is not only a short-term intervention, but also involves long-term follow-up and referral of cases to regular psychiatric management. We used PubMed (http://www.ncbi.nlm.nih.gov/pubmed) to search for papers related to the Chi-Chi Earthquake and the Morakot Typhoon published between January 2001 and November 2011. We found that 33 articles are involved in seven topics. The most common disaster-related psychiatric diagnoses were major depressive episodes and posttraumatic stress disorder. The prevalence of posttraumatic stress disorder ranged from 8.0% to 34.3% in Taiwan after the 1999 Earthquake. However, lifetime and current prevalence for psychiatric disorders ranged from 1% to 74%, affecting women twice more than men. Because disasters are becoming increasingly common, it is vital to train a sufficient number of specialists with guidelines for standard clinical treatment, and to create a standard operating procedure for reducing traumatic conditions.
