Abstract
Biological disasters pose a growing challenge in the 21st century, significantly impacting global society. Taiwan has experienced such disasters, resulting in long-term consequences like loss of life, trauma, economic decline, and societal disruptions. Post-disaster, mental health issues such as fear, anxiety, depression, post-traumatic stress disorder (PTSD), and stress surge, accompanied by increased suicide rates. The Coronavirus disease 2019 (COVID-19) (also called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) pandemic, recognized as a biological disaster, triggered lockdowns and quarantines in Taiwan, causing lifestyle changes, economic recession, and so on. These shifts may elevate uncertainty about the future, intensifying mental stress and leading to a rise in various mental illnesses. This article reviews mental health studies conducted in Taiwan during the pandemic, emphasizing the need to integrate this research for future preparedness and interventions regarding the mental health impacts of biological disasters, including COVID-19. Further research is essential to explore long-term effects, interventions, and generalizability.

Abstract
Introduction The coronavirus disease 2019 (COVID-19) pandemic has had an impact on patients with substance use disorder (SUD). We aimed to investigate factors associated with confidence and adherence to governmental policies against COVID-19 (social desirability) among patients with SUD. Methods This cross-sectional study was conducted during 2020 to 2021. Patients with SUD and healthy controls were recruited. The severity of sleep disturbance, social desirability, drug dependence, vaccine worries, other psychological burdens and demographic variables were collected through self-administrated questionnaires. Differences between the SUD and control groups were estimated. Hierarchical regression analysis was used to identify significant relationships between social desirability and other factors. Results In total, 58 of patients with SUD and 47 healthy controls were recruited. The patients with SUD had a lower level of social desirability and more severe sleep disturbance than the control group. Older age, more severe sleep disturbance, lower level of drug dependence, and lower level of vaccine worries were significantly associated with a higher level of social desirability among the patients with SUD. Conclusion Our results show the importance of timely interventions for drug dependence and to address vaccine worries in patients with SUD.

Abstract
INTRODUCTION The intention of chemsex-practicing gay and bisexual men and other men who have sex with men (GBMSM) to reduce their drug use is an important factor for the utilization of harm reduction services. This study aimed to examine data from an integrated sexual health services center to understand the relationship between the intention to reduce chemsex behavior and chemsex-related utilization of mental health services among GBMSM who engage in chemsex. METHOD We used data collected from Healing, Empowerment, Recovery of Chemsex (HERO), an integrated health center in Taiwan, between November 2017 and December 2021. As the baseline, clients were asked to rate the current and ideal proportions of their sexual activities that involved the use of MDMA, ketamine, methamphetamine, GHB/GBL, or mephedrone. Having the intention to reduce chemsex was defined as having a lower proportion of ideal engagement compared to actual engagement. The data on the use of the services provided at HERO were linked to the survey responses and compared to information gathered during regular follow-up visits. Univariable and multivariable logistic regression analyses and a Poisson regression analysis were performed on the data. RESULTS A total of 152 GBMSM reported engaging in chemsex, of whom 105 (69.1%) expressed the intention to reduce their chemsex behavior. Service utilization ranged from 23.0% for participating in meetings of a chemsex recovery group, 17.1% for visiting a mental health clinic, and 10.5% for using both of these services. The intention to reduce chemsex behavior significantly associated with visiting a mental health clinic (aOR = 4.68, p < 0.05), but its association with attending meetings of a chemsex recovery group was only marginally significant (aOR = 2.96, p < 0.1). Other factors that remained significantly associated with service use were a high frequency of substance use and living with HIV. CONCLUSION Comprehensive harm reduction strategies, which touch on mental health, drug use management and recovery, are needed for those who want to reduce their chemsex behavior. Public health practitioners should endeavor to raise awareness of resources that are available for people who engage in chemsex and to minimize the barriers blocking their access to the appropriate services.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic has caused a heavily burden on healthcare workers (HCWs) worldwide. The aim of this study was to compare differences in psychological and social impact between two waves of the pandemic among first- and second-line HCWs in Taiwan. The current study derived data from two cross-sectional surveys conducted in 2020 and 2021. Levels of depression, sleep disturbance, psychological distress, social impact, and demographic variables were collected through self-reported questionnaires. The independent t test was used to compare differences in scores between the first and second wave of the pandemic. Differences between first- and second-line HCWs were also analyzed. A total of 711 HCWs in the first wave and 560 HCWs in the second wave were recruited. For the first- and second-line HCWs, the social impact during the second wave was higher than during the first wave, and they expressed a higher intention to maintain social distancing and were more aware of the pandemic overseas in the second wave. The first-line HCWs had a trend of worse sleep quality during the second wave. In addition, sleep quality was worse in the first-line HCWs than in the second-line HCWs during both waves. The second-line HCWs expressed a greater desire to seek COVID-19-related information than the first-line HCWs during the first wave, and more intended to maintain social distancing during the second wave. Our results show the importance of evaluating the social and mental health burden of HCWs, and especially first-line workers.

Abstract
OBJECTIVES Schizophrenia is a serious mental illness. The serum protein biomarkers of schizophrenia were explored using isobaric tags for relative and absolute quantitation (iTRAQ) technology. The underlying function of the identified protein biomarker was also investigated. METHODS We first collected serum samples from 12 schizophrenia patients and 12 healthy control (HC) subjects, followed by global screening with iTRAQ and tandem mass spectrometry (LC-MS/MS). In total, 691 serum proteins were detected and eight proteins, including ZYX, OSCAR, TPM4, SDPR, BST1, ARGHDB, ITIH5 and SH3BGRL3, were selected for further specific validation with enzyme-linked immunosorbent assay (ELISA) on the serum samples from 52 schizophrenia patients and 50 HC subjects. RESULTS Schizophrenia patients had significantly lower serum level of BST1 and higher ITIH5 level than the HC subjects did. Using the levels of BST1, ITIH5 and OSCAR combined with machine learning algorithm, we developed a prediction model of schizophrenia with an auROC value 0.78. Moreover, in vitro cell assay confirmed that BST1 significantly repressed neutrophil infiltration through endothelial layer, highlighted the anti-inflammation nature of BST1. CONCLUSIONS Four novel protein markers (BST1, ITIH5, SDPR, and OSCAR) of schizophrenia were identified, and BST-1 could serve as a serum protein biomarker involved in neutrophil infiltration in schizophrenia.

Abstract
Substance and alcohol use in the workplace have become a global health burden; however, the etiologies have seldom been explored. The aims of this study were to develop a Workplace Substance Reuse Questionnaire (WSRQ) to measure the multidimensional factors associated with the reuse of alcohol or illegal substances in the workplace. The predictors of reuse were also investigated. The WSRQs for alcohol (WSRQ-Alc) and illegal substances (WSRQ-Sub) were composed of 15 and 13 items, respectively. Factors associated with workplace substance reuse included workplace environment, workload, social interaction in the workplace and other cues. Construct validity and reliability were performed to verify the questionnaires. Multivariate linear regression was conducted to estimate the associations between the factors and WSRQ score. A total of 90 patients with substance or alcohol use disorder were recruited. The results demonstrated that the WSRQ-Alc and WSRQ-Sub had acceptable reliability, with variance of 76.4% and 75.4%, respectively. The confirmatory factor analysis fit indices also indicated the adequacy of the model. A longer duration of alcohol use (β = 0.44; p = 0.002) and higher frequencies of changing job (β = 0.32; p = 0.027) and working part time (β = 0.32; p = 0.028) were significantly associated with higher WSRQ-Alc score. Our results highlight the importance of abstinence treatment and job referral for individuals with alcohol or substance use. Further studies are warranted to help extend the applicability and generalizability of the WSRQ.

Abstract
Vaccine hesitancy has become a major public health problem among healthcare workers (HCWs) in this coronavirus disease 2019 (COVID-19) pandemic. The aim of this study was to examine the relationship between societal adaptation and vaccine worries and the mediating effects of posttraumatic stress disorder (PTSD) indicators in HCWs. A total of 435 HCWs (327 women and 108 men) were recruited. Their levels of societal adaptation were evaluated using the Societal Influences Survey Questionnaire (SISQ). Their severity and frequency of PTSD symptoms were examined using the Disaster-Related Psychological Screening Test (DRPST). The severity of vaccine worries was assessed using the Vaccination Attitudes Examination (VAX) Scale. The relationships among societal adaptation, PTSD, and vaccine worries were examined using structural equation modeling. The severity of societal adaptation was positively associated with both the severity of PTSD and the severity of vaccine worries. In addition, the severity of PTSD indicators was positively associated with the severity of vaccine worries. These results demonstrated that the severity of societal adaptation was related to the severity of vaccine worries, either directly or indirectly. The indirect relationship was mediated by the severity of PTSD. Societal adaptation and PTSD should be taken into consideration by the community of professionals working on vaccine hesitancy. Early detection and intervention of PTSD should be the objectives for programs aiming to lower vaccine hesitancy among HCWs.

Abstract
Background: The coronavirus infection disease 2019 (COVID-19) pandemic is likely to put healthcare professionals across the world in an unprecedented situation. Methods: A total of 683 healthcare workers were recruited in this study. Short form-12 items (SF-12), Societal Influences Survey Questionnaire (SISQ), and Disaster-Related Psychological Screening Test (DRPST) were used to survey participants. Multiple linear regression and structural equation model (SEM) were used to explore the possible factors to the societal influences and quality of life. Results: After multiple linear regression analysis, female, older, more education years, married, regular intake, and posttraumatic stress disorder (PTSD) frequency had positive association with SISQ. To physical component summary (PCS) of SF-12, chronic illness, sleep score, PTSD frequency, and social distance had negative association, and exercise habits had positive association. A mental component summary (MCS) value of SF-12, age, participate in social activities, and social information had positive association, and PTSD frequency, sleep score, social anxiety, and depression had negative association. Under SEM analysis, PTSD had positive influence on SISQ. Sleep score and MCS value had negative influences on SISQ. PTSD severity, older age, sleep score, smoking, and nursing staff had negative influences on PCS value. Young age, PTSD frequency, sleep score, and depression had negative influences on MCS value. Conclusion: Healthcare team members with severe PTSD symptoms suffered more societal influences. Relative to PTSD severity, PTSD frequency was more important to the quality of life. Members of older age who frequently participate in clubs, volunteers, or charity activities had better mental life quality.

Abstract
BACKGROUND The outbreak of coronavirus disease 2019 (COVID-19), like severe acute respiratory syndrome (SARS), provokes fear, anxiety and depression in the public, which further affects mental health issues. Taiwan has used their experience of the SARS epidemic for the management of foreseeable problems in COVID-19 endemic. AIM/OBJECTIVE This review summarizes issues concerning mental health problems related to infectious diseases from current literatures. RESULTS In suspected cases under quarantine, confirmed cases in isolation and their families, health care professionals, and the general population and related effective strategies to reduce these mental health issues, such as helping to identify stressors and normalizing their impact at all levels of response as well as public information and communication messages by electronic devices. The importance of community resilience was also addressed. Psychological first aid, psychological debriefing, mental health intervention and psychoeducation were also discussed. Issues concerning cultures and religions are also emphasized in the management plans. CONCLUSION Biological disaster like SARS and COVID-19 not only has strong impact on mental health in those being infected and their family, friends, and coworkers, but also affect wellbeing in general public. There are evidenced that clear and timely psychoeducation, psychological first aid and psychological debriefing could amileorate negative impact of disaster, thus might also be helpful amid COVID-19 pandemic.

Abstract
BACKGROUND The experiences of professionals in well-established recovery-oriented programs are valuable for professionals in similar practice settings. This study explored professionals' experiences with providing recovery-oriented services in community psychiatric rehabilitation organizations. METHODS Semi-structured interviews were conducted with 14 professionals from five recovery-oriented psychiatric rehabilitation organizations in Taiwan. The interviews were recorded and transcribed verbatim. Thematic analysis was used for the qualitative data analysis. RESULTS The analyses documented three main themes with 13 subthemes. Recovery-oriented service implementation included seven subthemes: Enabling clients to set their own goals and make decisions, using a strengths-based approach, establishing partnerships with clients, improving individuals' self-acceptance, encouraging community participation, seeking family, peer, and organizational support, and building team collaboration. Problems with implementing recovery-oriented services included limited policy and organizational support, a lack of understanding of recovery among professionals, stigma, clients' lack of motivation or self-confidence in their own ability to achieve recovery, and passive or overprotective family members. Strategies to resolve implementation problems included policy changes and organizational support, improving the recovery competence and confidence of professionals, and family and public education. CONCLUSIONS To date, this is the first known study examining the perspectives of mental health professionals who have experience implementing recovery-oriented services in Asia. The participants identified family collaboration, anti-stigma efforts, and changes in policy and attitudes as critical to successful implementation and delivery of recovery-oriented services.

Abstract
Cognitive deficits, which are core manifestations in schizophrenia and exhibit a limited response to antipsychotic treatment, contribute to poor treatment outcomes and functional disability. Evidence on the effect of aerobic walking (AW) and exercise intensity on cognitive function in patients with schizophrenia is lacking. In total, 79 patients with schizophrenia were recruited for a 12-week randomized control trial and allocated to the treatment-as-usual (TAU, n = 38) and treatment-as-usual plus AW (TAW, n = 39) groups. The TAW participants joined a supervised 12-week AW program consisting of 30-min sessions five times per week while wearing a Fitbit Charge 2 device. Cognitive function was evaluated using the Brief Assessment of Cognition in Schizophrenia. After randomization, 67 (34 TAU and 33 TAW) participants joined the 12-week trial and were included in the intention-to-treat analysis. Multivariate general linear model repeated measures analysis revealed no significant time × group interaction effect on cognitive function changes between the TAU and TAW groups and a marginally significant group effect on verbal fluency (p = 0.09). The interaction effect of time and treatment group on verbal fluency (p = 0.05) was marginally significant between the high and low AW intensity groups, whereas a significant group effect on attention and processing speed (p = 0.04) was observed. Supervised 12-week AW of moderate intensity may have potential cognitive benefits for patients with schizophrenia.

Abstract
Psychiatric hospitals play an important role in supporting patients with mental illness to relieve symptoms and improve functioning in a physically and psychologically safe environment. However, these hospitals are also vulnerable to emerging infectious diseases. In early 2020, a psychiatric hospital and a psychiatric unit were reported to have nosocomial coronavirus disease 2019 (COVID-19) infection. A large number of patients and staff were severely impacted. This type of nosocomial infection threatens patient safety and quality of care. By learning from previous experiences of severe acute respiratory syndrome (SARS) and previous studies, psychiatric hospitals can provide safeguards to prevent nosocomial infection among patients and staff during an epidemic or biological disaster. These strategies include a series of actions such as following national guidelines for infection control, reserving adequate support for disinfection equipment, providing relevant and sufficient pro-service and in-service education and training, establishing regular surveillance of hand hygiene habits, proper communication and health education, and providing opportunities for vaccination if possible. Based on the harm reduction concept, staff division of office breaks and ward classification and shunting are recommended and should be further implemented.

Abstract
Pre-exposure prophylaxis (PrEP) has proven to be effective in reducing the risk of HIV transmission in uninfected individuals who engaged in sexual activity with HIV-infected partners. Serodiscordant couples are the key targets of PrEP implementation. The study aimed to compare awareness of and willingness to use PrEP and anticipated condom use among 112 HIV-serodiscordant couples: 32 heterosexuals couples, 70 men who have sex with men (MSM) couples, and 10 people who inject drugs (PWID) couples. A cross-sectional study was conducted in an AIDS designated hospital in Taiwan. The PrEP survey for discordant couples included questions on awareness of non-occupational post-exposure prophylaxis (nPEP) and PrEP, attitudes toward PrEP, anticipated condom use if using PrEP, and sexual behaviors. Overall, 46.2% were aware of PrEP, only 33% were willing to take PrEP, and 44.6% would continue condom use if they were taking PrEP. Among the three key populations, MSM couples had the highest awareness of and willingness to use PrEP. Awareness of and willingness to use PrEP did not differ by HIV status, with moderate agreement (Cohen's Kappa coefficient: 0.56) between HIV-serodiscordant partners. Both HIV-serodiscordant partners' willingness to use PrEP was significantly associated with being MSM (adjusted odds ratio (AOR), 4.28 [1.28-14.30], p = 0.018), previous receipt of nPEP (AOR, 6.98 [1.23-39.65], p = 0.028), anticipated condom use (AOR, 0.14 [0.05-0.41], p < 0.001), and income ≥ NT$30,000 per month (AOR, 2.25 (0.99-5.04), p = 0.05). Policy makers need to consider the differences among key populations to scale up PrEP implementation. More efforts should be focused on improving awareness of and willingness to use PrEP among heterosexual and PWID serodiscordant couples to scale up PrEP implementation in Taiwan.

Abstract
Objective The Brief Assessment of Cognition in Schizophrenia (BACS) is a cognitive assessment tool used to measure the broad aspects of cognition that are most frequently impaired in patients with schizophrenia. This study aims to develop the normative data of the Chinese version of the BACS among the Mandarin-speaking population. Method This cross-sectional study included 382 healthy participants (age range: 19-79 years; mean age: 48.0 ± 16.7 years, 47.6% men) in Taiwan, who were evaluated with the BACS. Means and standard deviations of subtests and composite scores were arranged by age group and gender. The Z-scores calculated based on the U.S. norms were compared to our scores based on the norms established in this study. Results The raw scores of all the BACS tests (verbal memory, digit sequencing, token motor test, verbal fluency, symbol coding, and Tower of London) were negatively correlated with participants' age. Women were superior to men in verbal memory, but inferior to them in executive function. Furthermore, applying the U.S. norms of the BACS to determine the performance of the Chinese BACS results in bias with regard to verbal memory, token motor test, verbal fluency, symbol coding, Tower of London and composite score. Conclusions These findings demonstrate that directly applying western cognitive norms to a Mandarin-speaking population can cause biased interpretations. The results of this study can be an important reference for clinical settings and research related to cognitive assessments in Mandarin-speaking Chinese populations.

Abstract
BACKGROUND Oxidative stress has been implicated in the psychopathology of schizophrenia. Cysteine, a semi-essential amino acid, is the precursor of the antioxidant glutathione. The aim of this study was to investigate the differences in serum levels of cysteine between patients with schizophrenia and healthy controls. The relationships between levels of cysteine, psychopathology and cognitive function were also explored. METHODS We recruited 65 patients with schizophrenia and 65 age- and gender-matched healthy controls. Blood samples were collected to determine the serum levels of cysteine and plasma levels of metabolic parameters. The cognitive function of participants was assessed using the Brief Assessment of Cognition in Schizophrenia (BACS). The psychopathology of schizophrenic patients was evaluated using the Positive and Negative Syndrome Scale. RESULTS Serum cysteine levels were significantly higher in schizophrenic patients than in controls (P<0.001). In patients with schizophrenia, serum levels of cysteine were positively correlated with cognitive function in terms of verbal memory (P=0.013), working memory (P=0.004), verbal fluency (P=0.027), attention and processing speed (P=0.025), executive function (P=0.024) and the composite score on the BACS (P=0.013). In healthy controls, no significant correlation was observed between cysteine level and cognitive function. CONCLUSIONS These findings suggest that oxidative stress may be involved in the pathogenesis of schizophrenia, and compensatory elevated levels of cysteine may serve as an indicator of cognition preservation. Further prospective studies are warranted to investigate the dynamic alterations in cysteine and the underlying pathophysiology of schizophrenia.

Abstract
OBJECTIVE The mental health of caregivers of individuals with disabilities is frequently neglected. This study investigated mental health status and Suicidal Ideation (SI) among caregivers and examined the predictive factors for SI. METHOD Caregivers of individuals with physical or mental disabilities in a tertiary hospital in southern Taiwan were recruited through snowball sampling. They were assessed by self-report questionnaires, consisting of the Taiwanese Depression Questionnaire and a subset of the three-item Chinese Health Questionnaire, to assess probable depression and common mental disorders (CMDs), with cutoff points of 19 and 3, respectively. RESULTS Among 255 caregivers, 32.9% had probable depression, 37.6% had probable CMDs, and 18.8% experienced SI. The level of SI was correlated with primary caregivers (p=0.015), lack of support from co-caregivers (p=0.023), caring for younger patients (p=0.010), caring for patients with mental disability (p=0.019) or catastrophic diseases (p=0.005), and caregivers' probable depression (p<0.001) and CMDs (p<0.001). Regression analysis predicted the greatest SI among caregivers caring for younger patients (odds ratio [OR]=0.98, p=0.048) and for patients with catastrophic diseases (OR=3.15, p=0.008), as well as for caregivers with probable depression (OR=3.90, p=0.010) or CMDs (OR=9.40, p<0.001). CONCLUSIONS When examining SI, clinicians should be aware of the mental health of caregivers who are responsible for people with disability. In particular, they should be vigilant regarding caregivers of individuals who are of younger age or have catastrophic diseases and regarding caregivers who exhibit probable depression and CMDs.

Abstract
BACKGROUND β-hydroxybutyrate (β-HB) and pyruvate have been associated with the brain energy utilization, which may play a role in the pathophysiology of schizophrenia. In this prospective study, we aim to investigate the trends of β-HB and pyruvate levels, metabolic changes, and cognitive function in schizophrenia patients receiving antipsychotic treatment. OBJECTIVE We recruited 38 schizophrenia patients who had been treated with antipsychotics for 12 weeks, as well as 38 healthy age- and gender-matched subjects. Blood samples were taken from the patients at baseline and week 12 to determine the serum levels of β-HB, pyruvate, and metabolic parameters, while blood samples of the healthy controls were taken at baseline. We evaluated the psychopathology using the Positive and Negative Syndrome Scale and cognitive function using the Brief Assessment of Cognition in Schizophrenia. RESULTS During the 12-week follow-up period, the β-HB levels in patients with schizophrenia showed a decreasing trend, particularly in those undergoing treatment with aripiprazole or ziprasidone. The serum levels of β-HB in patients at baseline and week 12 were both higher than the levels in the healthy controls. Among the schizophrenia patients, changes in β-HB were positively correlated with changes in executive function. On the other hand, serum pyruvate levels remained steady during the 12-week follow-up period, and we found no significant correlation between pyruvate changes and changes in cognitive function or clinical symptoms. CONCLUSION Our findings indicate that β-HB may possess a potential indicator of energy utilization and have a protective role in executive function in patients with schizophrenia. Additional longitudinal studies with a larger sample size and longer follow-up periods are necessary to identify the relationship of metabolite regulation and cognitive function during schizophrenia patients' exposure to antipsychotics.

Abstract
The optic lobe is the largest brain area within the central nervous system of cephalopods and it plays important roles in the processing of visual information, the regulation of body patterning, and locomotive behavior. The oval squid Sepioteuthis lessoniana has relatively large optic lobes that are responsible for visual communication via dynamic body patterning. It has been observed that the visual behaviors of oval squids change as the animals mature, yet little is known about how the structure of the optic lobes changes during development. The aim of the present study was to characterize the ontogenetic changes in neural organization of the optic lobes of S. lessoniana from late embryonic stage to adulthood. Magnetic resonance imaging and micro-CT scans were acquired to reconstruct the 3D-structure of the optic lobes and examine the external morphology at different developmental stages. In addition, optic lobe slices with nuclear staining were used to reveal changes in the internal morphology throughout development. As oval squids mature, the proportion of the brain making up the optic lobes increases continuously, and the optic lobes appear to have a prominent dent on the ventrolateral side. Inside the optic lobe, the cortex and the medulla expand steadily from the late embryonic stage to adulthood, but the cell islands in the tangential zone of the optic lobe decrease continuously in parallel. Interestingly, the size of the nuclei of cells within the medulla of the optic lobe increases throughout development. These findings suggest that the optic lobe undergoes continuous external morphological change and internal neural reorganization throughout the oval squid's development. These morphological changes in the optic lobe are likely to be responsible for changes in the visuomotor behavior of oval squids from hatching to adulthood.

Abstract
Past research has indicated gender differences in the clinical characteristics and course of schizophrenia. In this study, we investigated whether gender differences in the manifestation of schizophrenia are correlated with neurosteroids, including dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEA-S), and pregnenolone. We further explored the potential relationship between the aforementioned neurosteroids and psychopathology. We recruited 65 schizophrenic patients (36 males and 29 females) and 103 healthy control subjects (47 males and 56 females) and obtained blood samples from the subjects in the morning while in a fasting state to determine the serum levels of DHEA, DHEA-S, and pregnenolone. The psychopathology and mood symptoms of patients with schizophrenia were evaluated using the Positive and Negative Syndrome Scale (PANSS) and 17-item Hamilton Depression Rating Scale, respectively. Compared to the male control subjects, male patients with schizophrenia had significantly lower serum levels of DHEA and pregnenolone. In males with schizophrenia, the serum levels of DHEA and DHEA-S were associated with the age of onset and the duration of illness, while pregnenolone levels were associated with general symptoms of the PANSS. However, none of the neurosteroid levels were different between the female patients with schizophrenia and the female controls, and no significant correlation between neurosteroid levels and psychopathology evaluations was found among the schizophrenic females. Neurosteroids, including DHEA, DHEA-S, and pregnenolone, are involved in the pathophysiology of schizophrenia in male patients, but not in female ones. Therefore, our findings suggest that neurosteroids may be associated with gender differences in susceptibility to schizophrenia.

Abstract
The disturbances of β-hydroxybutyrate (β-HB) and pyruvate are linked with impaired brain energy utilization which involves in the psychopathology of schizophrenia. This study investigates the difference in levels of β-HB and pyruvate between patients with schizophrenia and healthy controls, and explores their relationship with metabolic profiles and disease characteristics. We recruited 54 physically-health schizophrenic patients and 54 age- and gender-matched healthy control subjects. Blood samples were gathered to determine the serum levels of β-HB and pyruvate and plasma levels of metabolic profiles, including fasting glucose, triglycerides, total cholesterol, high- and low-density lipoprotein-cholesterol and adiponectin. The disease characteristics and psychopathology of patients with schizophrenia were assessed by using the Positive and Negative Syndrome Scale. Of patients with schizophrenia, serum levels of β-HB were significantly correlated with fasting glucose (p=0.007) and triglycerides (p=0.021). Pyruvate was significantly correlated with fasting glucose (p=0.018), total cholesterol (p=0.005), triglycerides (p=0.014) and LDL-C (p=0.006). After controlling the metabolic profiles, β-HB was still significantly higher in schizophrenia patients than in controls (p<0.001), but no difference in pyruvate was observed. Neither β-HB nor pyruvate was significantly correlated with disease characteristics. However, pyruvate was higher in patients treated with olanzapine or clozapine than in those treated with other antipsychotics (p=0.048). Findings suggest that schizophrenic patients had significantly higher serum levels of β-HB than control subjects, possibly reflecting higher demands in energy utilization. Serum levels of β-HB, rather than pyruvate, may act as a potential indicator of energy utilization impairment for schizophrenia.

Abstract
High cost of pre-exposure prophylaxis (PrEP) is a major concern for acceptability. This study determined the willingness of men who have sex with men to self-pay for PrEP and factors associated with the likelihood of condom use if taking PrEP. The Taiwan 2014 MSM Online Sex Survey was conducted and data such as demographics, attitudes toward PrEP, and sexual behaviors in the previous 3 months were collected. Of the 1,151 MSM who participated, 56% were willing to take PrEP, but only 23% were willing to self-pay $340 for PrEP. Willingness to self-pay for PrEP was significantly associated with the previous receipt of nonoccupational post-exposure prophylaxis (adjusted odds ratio [AOR], 3.02, 95%CI [1.49, 6.12]), and positive attitudes toward PrEP (AOR, 3.02, 95%CI [2.19, 4.17]). Of MSM who are willing to use PrEP, 73.6% would maintain condom use if taking PrEP. If PrEP is made available in Taiwan, more efforts should be focused on increasing awareness of MSM who are practicing risky behaviors.

Abstract
It has become popular for men who have sex with men (MSM) to use mobile-phone geosocial networking applications (mobile apps) to find sex partners. A cross-sectional online survey was conducted in Taiwan to compare the sexual and substance-use behaviors of MSM seeking sex partners through the internet and mobile apps. Of the 1060 participants, 65.8% used the internet via computer and 37.7% used a mobile app to find sexual partners, while 30.3% used recreational drugs or alcohol in the previous 6 months. MSM who exclusively used mobile apps to seek sex partners were significantly more likely than MSM seeking sex via computer to be older, to have used recreational drugs or alcohol, and to have sex with HIV-positive partners. Additionally, using mobile apps to seek sex partners was significantly associated with having sex with online partners through either mobile apps or computer-based internet use (adjusted odds ratio (AOR), 7.12 [3.87-13.11]), self-reporting as HIV-positive (AOR, 2.24 [1.12-4.12]), using recreational drugs (AOR, 1.67 [1.21-2.32]), having disclosed HIV status to sexual partners (AOR, 1.44 [1.03-2.02]), and having sex with HIV-positive partners (AOR, 1.81 [1.06-3.10]). In conclusion, the mobile apps may serve as a feasible platform for HIV-positive MSM to find other HIV-positive partners.

Abstract
OBJECTIVE A test battery that measures cognitive function impairment in patients with schizophrenia, the Brief Assessment of Cognition in Schizophrenia (BACS), has been translated into various languages and validated. This study aimed to test the reliability and validity of the Chinese version of the BACS in a Chinese-speaking population. METHODS All participants in this study (66 patients with schizophrenia [mean age: 41.2 years, 57.6% male] and 66 age- and sex-matched healthy controls) were from Taiwan and assessed using the BACS and the University of California, San Diego (UCSD) Performance-Based Skills Assessment, Brief Version (UPSA-B). Thirty-eight of the 66 patients with schizophrenia received a reassessment using the BACS. RESULTS The BACS had good test-retest reliability, and all BACS subtests had statistically insignificant practice effects. Principal components analysis demonstrated that a one-factor solution best fits our dataset (60.9% of the variance). In both patients and controls, the BACS composite scores were positively correlated with all BACS subscales (P<0.001) and UPSA-B scales (P<0.001). Furthermore, all BACS subtests (verbal memory, working memory, motor speed, verbal fluency, attention and processing speed, and executive function) significantly differentiated patients with schizophrenia from healthy controls (P<0.001), and the BACS composite score had the best discriminative validity (P<0.001). CONCLUSION The Chinese version of the BACS exhibits satisfactory psychometric properties, including high test-retest reliability, high internal consistency, acceptable concurrent validity, and good discriminant validity. We suggest that the BACS is a reliable and practical tool for assessing cognitive function in patients with schizophrenia.

Abstract
Firefly luminescence is an intriguing phenomenon with potential technological applications, whose biochemistry background was only recently established. The physics side of this phenomenon, however, was still unclear, specifically as far as the oxygen supply mechanism for light flashing is concerned. This uncertainty is due to the complex microscopic structure of the tracheal system: without fully knowing its geometry, one cannot reliably test the proposed mechanisms. We solved this problem using synchrotron phase contrast microtomography and transmission x-ray microscopy, finding that the oxygen consumption corresponding to mitochondria functions exceeds the maximum rate of oxygen diffusion from the tracheal system to the photocytes. Furthermore, the flashing mechanism uses a large portion of this maximum rate. Thus, the flashing control requires passivation of the mitochondria functions, e.g., by nitric oxide, and switching of the oxygen supply from them to photoluminescence.

Abstract
Background The Internet has become a popular venue for facilitating sex networking for men who have sex with men (MSM). Objective The study aimed to evaluate the effectiveness of Internet popular opinion leaders (iPOL) in disseminating information about the human immunodeficiency virus (HIV), increasing the frequency of HIV testing, and reducing risky behaviors among MSM in Taiwan. Methods A quasi-experimental study with a nonequivalent control website for comparison was used to estimate the effectiveness of iPOL. A community-level intervention, iPOL, was conducted at the Facebook social networking website and at top1069 as a control. The iPOLs actively disseminated HIV-related information via the platform of Internet opinion leaders and AIDS information center, and discussed and responded to questions or replied to Internet-using MSM. Results A total of 369 iPOLs posted 432 articles and 503 replies to others, influencing 959,088 persons on Facebook. A total of 1037 MSM, 552 (53.23%) from an intervention website and 485 (46.76%) from a control website, participated in the follow-up study survey (response rate 96%). At the 6-month follow-up after the intervention was conducted, MSM who visited the intervention website were more likely to receive HIV-related information (25.49% versus 10.47%, P<.001), discuss HIV issues with others (41.88% versus 23.79%, P<.001), review articles about HIV (90.58% versus 79.73%, P<.001), and be asked about or discuss HIV-related questions (51.11% versus 31.78%, P<.001) than those on the control website. In addition, MSM were more likely to have HIV tests within 6 months (43.89% versus 22.31%, P<.001) and consistently use condoms during anal sex with online sex partners than those using the control website (34.15% versus 26.19%, P=.004). Conclusions The study showed the feasibility and effectiveness of the iPOL intervention as an online HIV prevention program. These findings underscore the importance of disseminating HIV information online, as well as the challenges inherent in the efforts of iPOL to reduce HIV-related risky behaviors among Internet-using MSM.

Abstract
High-quality m-plane orientated ZnO films have been successfully grown on m-plane sapphire by using radio frequency magnetron sputtering deposition. The introduction of a nanometer-thick, low-temperature-grown ZnO buffer layer effectively eliminates inclusions of other undesirable orientations. The structure characteristics of the ZnO epi-layers were thoroughly studied by synchrotron X-ray scattering and transmission electron microscopy (TEM). The in-plane epitaxial relationship between ZnO and sapphire follows (0002)(ZnO) [parallel] (112[overline]0)(sapphire) and (112[overline]0)(ZnO) [parallel] (0006)(sapphire) and the ZnO/sapphire interface structure can be described by the domain matching epitaxy along the [112[overline]0](ZnO) direction. The vibrational properties of the films were investigated by polarization dependent micro-Raman spectroscopy. Both XRD and micro-Raman results reveal that the obtained m-ZnO layers are under an anisotropic biaxial strain but still retains a hexagonal lattice.

Abstract
We conducted an online behavioral survey to estimate the prevalence of online sex-seeking and substance use behaviors and to compare risky behaviors among men using different venues to seek sex with men. A cross-sectional online survey, the Asia Internet MSM Sex Survey, was conducted online from January 1 to February 28, 2010. Of the 1,645 participants enrolled from Taiwan, 72.4% reported the Internet as the main way of seeking sexual partners, 73.9% had had sex with partners found online, and 16% had used recreational drugs in the previous 6 months. There was no evidence to suggest that men who looked for sex through the Internet were more likely to engage in unprotected anal intercourse with their casual partners than those using other gay venues. Having had online sex partners in the previous 6 months was significantly associated with being young [adjusted odd ratio (AOR) = 0.97, 95% CI: 0.95-0.99], having had no steady partners in the previous year (AOR = 0.24, 95% CI: 0.15-0.39), having had more than five partners in the previous 6 months (AOR = 4.57, 95% CI: 2.95-7.11), having used recreational drugs in the previous 6 months (AOR = 2.24, 95% CI: 1.30-3.87), and having had an STI in the previous 6 months (AOR = 4.24, 95% CI: 1.59-11.30). In conclusion, because the Internet is a popular meeting place for MSM in Taiwan, effective and targeted prevention programs should be developed to minimize the HIV transmission risk in the Internet era.

Abstract
BACKGROUND People living with HIV (human immunodeficiency virus) are at a high risk of depressive symptoms attributed to disease progression and HIV-related stress. While depressive symptoms are difficult to detect, in HIV patients they may negatively impact upon quality of life, decrease adherence to antiretroviral therapies, and further exacerbate disease progression. PURPOSE Study purposes were to: (1) explore relationships among immune function indicators, perceived stress, social stigma and depressive symptoms and (2) identify depressive symptom indicators in HIV patients. METHODS Researchers recruited a total of 160 participants from infectious disease outpatient clinics at a university hospital in southern Taiwan. Chart reviews and four self-administered questionnaires (Beck Depression Inventory-II (BDI-II), Perceived Stress Scale, Multidimensional Scale of Perceived Social Support, and Social Impact Scale) were used to collect data. RESULTS Symptoms of depression (BDI >= 14) were observed in 68 (42.5%) patients and symptoms of major depression (BDI >= 29) in 25 (15.6%). We found immune function indicators negatively associated with depressive symptoms (p < .05) and perceived stress and social stigma positively associated with depressive symptoms (p < .01). Stepwise multiple regression analysis indicated that perceived stress and social stigma accounted for 44.4% of depressive symptom variance. CONCLUSION Findings suggest that reducing perceived stress and social stigma may positively affect perceived depressive symptoms in this population and may be referenced in future development of related interventions.

Abstract
The purpose of the study was to determine heroin dependence and risky behaviors associated with human immunodeficiency virus (HIV) infection among newly incarcerated injection drug users (IDUs). Three self-administrated questionnaires were collected among 450 newly incarcerated male heroin users during 2005-2007. Inmates were categorized as heroin-dependent if they met three or more of the six ICD-10 criteria. Heroin-dependent inmates had higher scores of bloodborne virus transmission risk than non-dependent IDUs (12.8 ± 16.0 vs. 7.2 ± 11.5, p < 0.001). Multiple logistic regression analysis indicated that heroin dependence was a significant moderator of the association between risky injection behaviors and HIV infection. It is crucial to integrate substance treatment with behavioral interventions into harm reduction programs to prevent bloodborne virus transmission among IDUs.

Abstract
Batch propionic acid fermentation of lactose by Propionibacterium acidipropionici were studied at various pH values ranging from 4.5 to 7.12. The optimum pH range for cell growth was between 6.0 and 7.1, where the specific growth rate was approximately 0.23 h(-1). The specific growth rate decreased with the pH in the acids have been identified as the two major fermentation products from lactose. The production of propionic acid was both growth and nongrowth associated, while acetic acid formation was closely associated with cell growth. The propionic acid yield increased with decreasing pH; It changed from approximately 33% (w/w) at pH 6.1-7.1 to approximately 63% at pH 4.5-5.0. In contrast, the acetic acid yield was not significantly affected by the pH; it remained within the range of 9%-12% at all pH values. Significant amounts of succinic and pyruvic acids were also formed during propionic acid fermentation of lactose. However, pyruvic acid was reconsumed and disappeared toward the end of the fermentation. The succinic acid yield generally decreased with the pH, from a high value of 17% at pH 7.0 to a low 8% at pH 5.0 Effects of growth nutrients present in yeast ex-tract on the fermentation were also studied. In general, the same trend of pH effects was found for fermentations with media containing 5 to 10 g/L yeast extract. However, More growth nutrients would be required for fermentations to be carried out efficienytly at acidic pH levels.

Abstract
Establishing the discriminative factors for unprotected sex among adolescents is essential for early identification of at-risk teens and for the prevention of unplanned pregnancy and sexually transmitted diseases. The aim of this study was to examine the discriminative effects of demographic, individual, family, peers, and school life factors on unprotected sex in a large-scale, representative adolescent population in Southern Taiwan. A total of 9,736 adolescent students were recruited into this study and completed the questionnaires. The multidimensional discriminative factors for unprotected sex were examined using chi2 automatic interaction detection analysis and logistic regression models. The results of the chi2 automatic interaction detection analysis revealed that having friends, using illicit drugs, being of an older age, suspension from school, and low family monitoring had discriminative effects on unprotected sex in adolescents. The logistic regression analysis further confirmed the discriminative effect of these factors. Because of the adverse effects of unprotected sex in adolescents, we suggest that parents and health professionals should pay attention to adolescents with the discriminative factors for unprotected sex identified in this study.

Abstract
Taiwan is experiencing an outbreak of human immunodeficiency virus infection among injection drug users. The purpose of the study was to determine the impact of a Transtheoretical Model-based HIV education program among drug-dependent inmates. A single group pre/post design was used to evaluate shortened impacts among 136 inmates who were arrested for illicit drug use and had attended a brief HIV education program in 2005. A repeated-measures analysis of variance indicated positive changes in AIDS knowledge (F > = 104.16, p < 0.001), self-efficacy to reduce HIV-risk behaviors (F = 26.5, p < 0.001), and readiness of change on substance use (F = 4.83, p = 0.03). The study findings showed that a brief TTM-based HIV education program can be effective for drug-dependent inmates.

Abstract
BACKGROUND Studies have shown that the validity of self-reported depression questionnaires may be influenced by somatic symptoms such as chronic pain. The purpose of this study was to compare the validity of two self-reported questionnaires, the Taiwanese Depression Questionnaire (TDQ) and the Beck Depression Inventory (BDI), for screening depression in patients with chronic pain. METHODS One hundred patients with chronic pain were enrolled and assessed using the TDQ, BDI, McGill Pain Questionnaire, and Structured Clinical Interview for DSM-III-R. Seventy-three of them were diagnosed with depressive disorders. Conventional validity indices of the TDQ and BDI were examined and compared. RESULTS Both the TDQ and BDI had satisfactory sensitivity, specificity, positive predictive value, and negative predictive value. Our results showed a trend that the validity of the TDQ was better than that of the BDI, and the validity of the cognitive/affective components of the TDQ was significantly better than that of the BDI. CONCLUSION Our results suggest that the TDQ is superior to the BDI in detecting depression in patients with chronic pain in Taiwan.

Abstract
Poor insight in schizophrenic patients is a common and multidimensional phenomenon. The purpose of this study was to explore the process of the formation of insight in patients with schizophrenia in remission. A qualitative design was used to analyze first-person narratives of 50 people with schizophrenia in remission. Face to face, semistructured interviews were conducted by investigators, and the narratives were transcribed verbatim. The results of our study showed that there were four stages of illness understanding in patients with schizophrenia: 1) the feeling that symptoms were unbearable or a loss of control, 2) comparisons of experiences with references, 3) perception that medication was working through trial and error experiments, and 4) awareness of illness after medication relieved symptoms. Insight formation is an active process in which schizophrenic patients gain knowledge about their medication, connect the association between their medication and symptoms, and realize they need to deal with issues.

Abstract
BACKGROUND Only a few studies on perceptions of uncertainty in illness have provided empirical evidence for the relationships of informational needs and the health locus of control with uncertainty among hospitalized women with gynecological diseases. The purpose of this study was to test Mishel's Theory of Uncertainty in Illness (1990) among women hospitalized with gynecological diseases. METHODS Taiwan. The convenience sample consisted of 81 hospitalized women with gynecological diseases, who were invited to complete a set of self-administered questionnaires prior to receiving any treatment. Path analysis was used to determine the relationships of informational needs and the health locus of control with uncertainty. RESULTS The study findings suggested that hospitalized women's information needs are substantial, and they reported lower levels of uncertainty during hospitalization. Women's experience of uncertainty may be elevated by decreasing the informational needs as moderated by the beliefs that their health outcomes are under the control of chance. Three predictors in this model, i.e., informational needs moderated by the interaction of chance control, years of education, and number of treatments explained 30% of the variance of uncertainty of hospitalized women with gynecological diseases. CONCLUSIONS The study findings suggest that healthcare professionals should carefully assess uncertainty levels among female patients with lower education and who believed that their health status depends upon external forces such as fate, luck, or chance.

Abstract
The solution structure and hydration of a DNA.RNA hybrid chimeric duplex [d(CGC)r(amamam)d(TTTGCG)]2 in which the RNA adenines were substituted by 2'-O-methylated riboadenines was determined using two-dimensional NMR, simulated annealing, and restrained molecular dynamics. Only DNA residue 7T in the 2'-OMe-RNA.DNA junction adopted an O4'-endo sugar conformation, while the other DNA residues including 3C in the DNA.2'-OMe-RNA junction, adopted C1'-exo or C2'-endo conformations. The observed NOE intensity of 2'-O-methyl group to H1' proton of 4am at the DNA.2'-OMe-RNA junction is much weaker than those of 5am and 6am. The 2'-O-methyl group of 4am was found to orient towards the minor groove in the trans domain while the 2'-O-methyl groups of 5am and 6am were found to be in the gauche (+) domain. In contrast to the long-lived water molecules found close to the RNA adenine H2 and H1' protons and the methyl group of 7T in the RNA-DNA junction of [d(CGC)r(aaa)d(TTTGCG)]2, there were no long-lived water molecules found in [d(CGC)r(amamam)d(TTTGCG)]2. This is probably due to the hydrophobic enviroment created by the 2'-O-methylated riboadenines in the minor groove or due to the wider minor groove width in the middle of the structure. In addition, the 2'-O-methylation of riboadenines in pure chimeric duplex increses its melting temperature from 48.5 degrees C to 51.9 degrees C. The characteristic structural features and hydration patterns of this chimeric duplex provide a molecular basis for further therapeutic applications of DNA.RNA hybrid and chimeric duplexes with 2'-modified RNA residues.

Abstract
BACKGROUND Homosexuality and sexual behavior have attracted great attention in the acquired immunodeficiency syndrome (AIDS) epidemic. This study primarily explores the risky behaviors and patterns of sexual behavior of male homosexuals in Taiwan. METHODS Comparison study methodology was adopted. Ninety-two male homosexuals, as the study group, were recruited from gay bars and gay organizations, and 91 male heterosexuals, with similar ages and educational levels, were recruited as a control group for comparison. Semi-structured interviews were carried out and anonymous questionnaires were self-administered. RESULTS (1) The mean age at the time of first sexual intercourse of the study group was younger than that of the control group. (2) The rate of having two or more sexual partners in the study group was significantly higher. (3) However, the rate of condom use during recent intercourse was higher in the control group than in the study group. (4) Sexual knowledge and attitudes toward sexuality in the study group were more open, but their sexual desires, as rated by the questionnaire, were more suppressed than those of the control group. (5) In terms of courtship, the study group was less constrained by the social values of marriage and tended to separate sex from love. CONCLUSION Similar to western studies, our study found that the study group in Taiwan adopted more risky sexual behaviors. Each group had its particular sexual behavioral pattern and subculture of sexuality. However, a longitudinal follow-up study with ethnographic perspective is necessary for a more sophisticated understanding of the trends and changes of sexual behavior in homosexuals.

Abstract
The solution structure and hydration of the chimeric duplex [d(CGC)r(aaa)d(TTTGCG)](2), in which the central hybrid segment is flanked by DNA duplexes at both ends, was determined using two-dimensional NMR, simulated annealing and restrained molecular dynamics. The solution structure of this chimeric duplex differs from the previously determined X-ray structure of the analogous B-DNA duplex [d(CGCAAATTTGCG)](2)as well as NMR structure of the analogous A-RNA duplex [r(cgcaaauuugcg)](2). Long-lived water molecules with correlation time tau(c)longer than 0.3 ns were found close to the RNA adenine H2 and H1' protons in the hybrid segment. A possible long-lived water molecule was also detected close to the methyl group of 7T in the RNA-DNA junction but not with the other two thymines (8T and 9T). This result correlates with the structural studies that only DNA residue 7T in the RNA-DNA junction adopts an O4'-endo sugar conformation, while the other DNA residues including 3C in the DNA-RNA junction, adopt C1'-exo or C2'-endo conformations. The exchange rates for RNA C2'-OH were found to be approximately 5-20 s(-1). This slow exchange rate may be due to the narrow minor groove width of [d(CGC)r(aaa)d(TTTGCG)](2), which may trap the water molecules and restrict the dynamic motion of hydroxyl protons. The minor groove width of [d(CGC)r(aaa)d(TTTGCG)](2)is wider than its B-DNA analog but narrower than that of the A-RNA analog. It was further confirmed by its titration with the minor groove binding drug distamycin. A possible 2:1 binding mode was found by the titration experiments, suggesting that this chimeric duplex contains a wider minor groove than its B-DNA analog but still narrow enough to hold two distamycin molecules. These distinct structural features and hydration patterns of this chimeric duplex provide a molecular basis for further understanding the structure and recognition of DNA.

Abstract
We have studied the hydration and dynamics of RNA C2'-OH in a DNA. RNA hybrid chimeric duplex [d(CGC)r(aaa)d(TTTGCG)](2). Long-lived water molecules with correlation time tau(c) larger than 0.3 ns were found close to the RNA adenine H2 and H1' protons in the hybrid segment. A possible long-lived water molecule was also detected close to the methyl group of 7T in the RNA-DNA junction but not to the other two thymine bases (8T and 9T). This result correlates with the structural studies that only DNA residue 7T in the RNA-DNA junction adopts an O4'-endo sugar conformation (intermediate between B-form and A-form), while the other DNA residues including 3C in the DNA-RNA junction, adopt C1'-exo or C2'-endo conformations (in the B-form domain). Based on the NOE cross-peak patterns, we have found that RNA C2'-OH tends to orient toward the O3' direction, forming a possible hydrogen bond with the 3'-phosphate group. The exchange rates for RNA C2'-OH were found to be around 5-20 s(-1), compared to 26.7(+/-13.8) s(-1) reported previously for the other DNA.RNA hybrid duplex. This slow exchange rate may be due to the narrow minor groove width of [d(CGC)r(aaa)d(TTTGCG)](2), which may trap the water molecules and restrict the dynamic motion of hydroxyl protons. The distinct hydration patterns of the RNA adenine H2 and H1' protons and the DNA 7T methyl group in the hybrid segment, as well as the orientation and dynamics of the RNA C2'-OH protons, may provide a molecular basis for further understanding the structure and recognition of DNA.RNA hybrid and chimeric duplexes.

Abstract
AIDS is not solely a medical issue but also has profound implications for family relationships. This case report using the concepts of family nursing and case management presents the concerns of a family living with AIDS. The data was collected through continuous contacts with a patient during December 1994 to August 1996. This report's findings indicate that the concerns of the family living with AIDS fall into seven categories: The reasons for HIV infection, how to meet the patient's sexual needs, suffering during health care seeking, the effectiveness and side-effects of anti-viral drugs, home care skills, the light of hope, death issues. Professional nurses should provide care to both the AIDS patient and the family members. Using social resources and cooperating with other health professionals can promote the quality of life for families living with AIDS.

Abstract
In order to assess the current seroepidemiology of hepatitis D virus (HDV) infection in Taiwan where hepatitis B virus (HBV) is hyperendemic, a total of 756 voluntary blood donors, 641 prostitutes, 1,014 patients with sexually transmitted diseases (STDs), and 628 drug abusers were studied. Radioimmunoassays were used for testing HBV infection markers and antibody against HDV (anti-HDV) among HBsAg carriers. The anti-HDV prevalence among HBsAg carriers was significantly higher in STD patients (9.6%), prostitutes (33.1%), and drug abusers (68.1%) than in blood donors from the general population (2.2%). The prevalence gradually increased with age in blood donors and STD patients, but reached a plateau at a young age in prostitutes and drug abusers. Males had a higher prevalence than females in blood donors (2.7% vs. 0), STD patients (8.2% vs. 7.5%), and drug abusers (69.0% vs. 57.1%), but the difference was not statistically significant. STD patients with syphilis had a higher prevalence (19.5%) than those affected with non-ulcerating STDs (5.3%). While unlicensed prostitutes had a lower prevalence (13.6%) than licensed prostitutes (44.9%), intravenous drug abusers had a higher prevalence (73.1%) than non-intravenous drug abusers (34.6%). There was a twofold increase in anti-HDV prevalence from 1986 to 1989 among prostitutes, but the prevalence remained unchanged in the general population and drug abusers. HDV infection remains limited to the high-risk groups and spread mainly by promiscuity and needle sharing in Taiwan.

Abstract
Polymorphonuclear leukocytes (PMN) infiltrating into tumors are assumed to be the result of a migration in response to a tumor-derived chemotactic factor. It is hypothesized that tumor-derived chemotactic factors, which are supposed to be in aggregates, can be exposed by proteolytic degradation of the tumor cell membrane protein (TCM). The TCM suspension made from either Sarcoma 180 or Ehrlich ascites tumor after incubation with Varidase at 37 degrees C for six to eight weeks is referred to as a degraded TCM protein (DTCM). The purpose of this study was to detect whether or not the DTCM was chemotactic for PMNs. Chemotactic activity was assayed by a sponge-matrix model and expressed in the number of PMNs infiltrating into the sponge per mouse after intrasponge injection of the DTCM, dose range, 0.4-0.005 mL. Maximal response to DTCM was restricted to the limited dose between 0.01 and 0.02 mL. Quantities of DTCM > 0.02 mL caused a response in roughly reciprocal proportion to the dose of DTCM. Changes in the circulating leukocyte count in response to an intravenous (i.v.) injection of DTCM was biphasic. The initial relative leukopenia was followed by leukocytosis within 24 hours in rats surviving the effect of DTCM doses < 0.5 mL. However, in rats with i.v. injections of higher doses, profound leukopenia was present at death. The mice, after an intraperitoneal (i.p.) injection of DTCM, dose range, 0.5-1.0 mL, died between 16 and 24 hours after the injection. The bone marrow of these mice showed complete depletion of PMNs.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Serum samples from 243 cases of primary hepatocellular carcinoma (PHC) and 302 non-PHC hospital controls were tested for hepatitis B virus (HBV) surface antigen (HBsAg), antibody to HBsAg (anti-HBs), antibody to HBV core antigen (anti-HBc), HBV e antigen (HBeAg) and antibody to HBeAg (anti-HBe) with radioimmunoassays using commercial kits. A total of 236 (97%) PHC cases and 302 (100%) hospital controls were positive for one or more HBV markers. While 188 (77%) PHC cases and 57 (19%) controls were positive for HBsAg, 44 (18%) PHC cases and 5 (2%) controls were positive for both BHsAg and HBeAg. Statistically significant associations with PHC were observed for HBsAg and HBeAg with an odds ratio (OR) of 10.0 and 3.2, respectively, when age, sex and other markers were adjusted. The stratification analysis of interactive effects of HBV infection markers on the development of PHC showed that HBeAg carrier status may increase PHC risk associated with HBsAg status.
