Honey in Alleviating Severe Oral Mucositis Among Head and Neck Cancer Patients Undergoing Radiation Therapy.

BACKGROUND/AIM: Aiming to resolve debates on honey's efficacy for radiotherapy-induced severe oral mucositis in head and neck cancer, we conducted a meta-analysis focused on randomized trials, primarily assessing severe mucositis incidence. Secondary outcomes included weight loss, pain management, and honey types. MATERIALS AND METHODS: A comprehensive literature search was conducted in PubMed, Embase, WOS, and the Cochrane Library up to December 2023. The analysis concentrated on randomized controlled trials that assessed the efficacy of honey, targeting the incidence of mucositis as the main outcome. Additional outcomes explored were weight loss, intolerable pain, and the specific types of honey used in interventions. Data analysis was performed using CMA software, and a funnel plot was employed to identify publication bias. RESULTS: The analysis of 176 records resulted in the inclusion of 10 studies with 599 patients receiving radiotherapy. The research showed that honey significantly reduced the occurrence of grade 3-4 mucositis (severe mucositis), provided significant pain relief, and had a positive effect on reducing weight loss. Regarding the type of honey used, no significant differences were found in their effectiveness in alleviating severe mucositis. CONCLUSION: Honey serves as an effective intervention for individuals with oral mucositis. It can be considered as an adjuvant in the management of clinical radiotherapy-associated oral mucositis, particularly for patients requiring prolonged use of anti-analgesic or antifungal medications.

Effects of length of residency on the development of physical and mental illnesses in immigrant women in Taiwan: a retrospective cohort study using nationwide data.

OBJECTIVES: The majority of female immigrants who are married in Taiwan often face a variety of stresses, which may lead to physical or mental illness. Yet few studies have validated the impact of length of residency on physical and mental health using large-scale data. This study combined five nationwide databases and explored the impact of length of residency in Taiwan on the physical and mental health of female marriage immigrants. DESIGN: This is a retrospective cohort study. SETTING: Taiwan. PARTICIPANTS: A total of 168 202 female immigrants, who were registered in the national health insurance database from 2001 to 2017, were enrolled for analysis. MEASURE: The length of residency was taken as the period from their first appearance in the national health insurance database to the end of 2017. Hypertension and diabetes were chosen as indices of physical health and depression as an index of mental health. Diagnosis standards were based on the International Classification of Disease, ninth or 10th Revision. RESULTS: The physical and mental health of the immigrants deteriorated with increasing time of residence in Taiwan. Immigrants who had resided in Taiwan for 5-10 years or ≥10 years, respectively, had a 5.8-fold (95% CI: 3.46 to 9.74) or 6.29-fold (95% CI: 4.61 to 8.59) higher adjusted risk of developing hypertension; a 3.97-fold (95% CI: 2.54 to 6.21) or 9.18-fold (95% CI: 5.48 to 15.38) higher adjusted risk of developing diabetes; and a 5.01-fold (95% CI: 3.14 to 8.01) or 12.19-fold (95% CI: 8.65 to 17.18) higher adjusted risk of developing depression than their counterparts who had lived in Taiwan for ≤5 years. CONCLUSION: These findings suggest the time elapsed since migration can be a factor in the deterioration of both physical and mental health among female marriage immigrants in Taiwan.

The use of premixed drugs in commodity packets in the population: prevalence and correlates revealed by the 2018 National Survey of Substance Use in Taiwan.

BACKGROUND: Administering premixed drugs in commodity packets was first reported in Asia in 2015, but there continues to be a dearth of related population-based data. This study aimed at examining (1) the prevalence of drug packet use in the population and (2) the sociodemographic profiles, particularly gender distribution, of drug packet users. METHODS: Data were derived from a survey of 18,626 Taiwanese civilians, aged 12-64 years, using stratified, multi-stage, random sampling in 2018. Participants anonymously completed a computer-assisted self-interview on tablet computers which covered the use and problematic use of illicit drugs/inhalants, prescription drugs and other psychoactive substances, among others. RESULTS: Approximately 1.46% of respondents had a lifetime use of illicit drugs, with drugs in commodity packets (0.18%) being ranked the fifth-most commonly used illicit drugs, higher than nitrous oxide (0.14%) and heroin (0.09%). Ten formats of drug packets were endorsed by users. Approximately 81.6% of persons with drug packet use had a lifetime use of other illicit drugs. The correlates of the use of drugs in commodity packets were similar to those of the exclusive use of other drugs except that there was a lack of gender differences in the use of drugs in commodity packets but not in the exclusive use of other drugs. CONCLUSION: Drugs in commodity packets have become a common way of administering illicit drugs in the population in Taiwan, and there were no gender differences among users. Our findings have implications for more efficient drug testing and culturally appropriate intervention for drug packet use.

The inhibitory role of microRNA-141-3p in human cutaneous melanoma growth and metastasis through the fibroblast growth factor 13-mediated mitogen-activated protein kinase axis.

Human cutaneous melanoma (CM) is a highly invasive malignancy arising from melanocytes, and accompanied by ever-increasing incidence and mortality rates worldwide. Interestingly, microRNAs (miRNAs) possess the ability to regulate CM cell biological functions, resulting in the aggressive progression of CM. Nevertheless, a comprehensive understanding of the underlying mechanism remains elusive. Accordingly, the current study sought to elicit the functional role of miR-141-3p in human CM cells in association with fibroblast growth factor 13 (FGF13) and the MAPK pathway. First, miR-141-3p expression patterns were detected in human CM tissues and cell lines, in addition to the validation of the targeting relationship between miR-141-3p and FGF13. Subsequently, loss- and gain-of-function studies of miR-141-3p were performed to elucidate the functional role of miR-141-3p in the malignant features of CM cells. Intriguingly, our findings revealed that FGF13 was highly expressed, whereas miR-141-3p was poorly expressed in the CM tissues and cells. Further analysis highlighted FGF13 as a target gene of miR-141-3p. Meanwhile, overexpression of miR-141-3p inhibited the proliferative, invasive, and migratory abilities of CM cells, while enhancing their apoptosis accompanied by downregulation of FGF13 and the MAPK pathway-related genes. Collectively, our findings highlighted the inhibitory effects of miR-141-3p on CM cell malignant properties via disruption of the FGF13-dependent MAPK pathway, suggesting a potential target for treating human CM.

Family, personal, parental correlates and behavior disturbances in school-aged boys with attention-deficit/hyperactivity disorder (ADHD): a cross-sectional study.

BACKGROUND: To evaluate the relationship among family, personal, parental correlates, and behavioral disturbances in boys with attention-deficit/hyperactivity disorder (ADHD). METHODS: We performed a hospital-based cross-sectional study. School-aged boys who first visited the hospital between 2000 and 2011 with ADHD were identified. Through medical records review, demographic information, family characteristics, personal characteristics, parental characteristics, and the Child Behavior Checklist (CBCL) collected during the first outpatient visit were retrieved. A T-score higher than 63 in the internalizing or externalizing subscale of the CBCL indicated severe behavioral disturbances in each domain. Multivariable logistic regression was used to evaluate the relationship between the correlates and behavioral disturbances. Eligible patients were further classified into groups without behavioral disturbance, with either only severe internalizing or only severe externalizing behaviors, or with both behaviors. Multivariable ordinal logistic regression was used to investigate the association between the correlates and the number of types of behavioral disturbances. RESULTS: A total of 1855 boys with ADHD were included. In the multivariable logistic regression, family factors, including being first-born, living in a family not with both parents, and family history of mental disorder, were associated with severe internalizing and externalizing behaviors. Personal factors, including prenatal complications, perinatal complications, and medical and psychiatric comorbidities, were associated with severe internalizing behaviors, but only prenatal complications and medical comorbidities were associated with severe externalizing behaviors. Parental factors were only associated with severe externalizing behaviors. A higher paternal education level had a protective effect, but younger motherhood increased the risk. In ordinal logistic regression, these factors were also associated with more types of behavioral disturbances. CONCLUSIONS: Multiple factors are related to behavioral disturbances in ADHD. Our study reported the association among family, personal, parental factors, severe internalizing behavior, severe externalizing behavior, and number of behavioral disturbances in boys with ADHD. However, the impacts differed as the behavior phenotypes varied. Further research is needed to better understand the heterogeneity of ADHD behavior.

The Interaction between Exercise and Marital Status on Depression: A Cross-Sectional Study of the Taiwan Biobank.

Few studies evaluating the relationship between depression and exercise consider peoples' socio-demographic characteristics. This cross-sectional study investigated the interaction between exercise and marital status and depression in Taiwanese adults. Data from the 2-item Patient Health Questionnaire (PHQ-2) was recruited from the Taiwan Biobank. Participants indicated their exercise status, showing 5015 no-exercise cases and 3407 exercise cases. Marital status, including unmarried, divorced or separated, and widowed, were all significant, especially among the no-exercise group. The relationship between exercise/no exercise and marital status was examined; no exercise and unmarried, divorced or separated, and widowed, as well as exercise and married were significant to PHQ-2. Gender was significant in both the married and unmarried groups. The association between exercise, marital status, gender, and education on PHQ-2 score was also significant. Married people, especially men, had lower depression scores. Additionally, exercise had a protective effect against depression for unmarried people, especially women.

Factors That Prevent Mosquito-Borne Diseases among Migrant Workers in Taiwan: Application of the Health Belief Model in a Church-Based Health Promotion Study.

BACKGROUND: Southeast Asian countries have long been considered epidemic areas for mosquito-borne diseases (MBDs), and most imported cases of infectious diseases in Taiwan are from these areas. Taiwanese migrant workers are mainly of Southeast Asian nationality, and of these, 22% are Filipino. Migrant workers' knowledge of MBDs and self-protection behaviors are beneficial to disease prevention and treatment. This study aims to understand the effectiveness of a health education intervention (HEI) for Filipino migrant workers in Taiwan and explores the factors affecting preventive practices. METHODS: The study was conducted between May to September 2018. Participants were recruited from two Catholic churches in Taichung City. A professional delivered a 30 min HEI in person, and a structured questionnaire was used to acquire and assess participants' knowledge, health beliefs, and preventive behaviors for MBDs before and after the intervention. RESULTS: A total of 291 participants were recruited. The intervention program showed a positive impact on the migrant worker's knowledge and the perceived severity, perceived benefits, perceived barriers, and preventive practices. Knowledge, perceived severity, and perceived barriers were factors influencing preventive practices in Filipino migrant workers. CONCLUSIONS: The results of this study demonstrated that we can direct our efforts towards three areas: improving foreign migrant workers' awareness of diseases, emphasizing the severity of the disease, and eliminating possible hindrances in the future. As one example, migrant workers could be proactively provided with routine medical examinations and multilingual health education lectures to improve knowledge and preventive practices to contain the spread MBDs.

Men's decrease and women's increase in harmful alcohol use from the 2014 to 2018 national surveys in Taiwan: A harbinger for an emerging national trend in East Asia?

BACKGROUND: Gender differences in alcohol use have narrowed in Western societies, but that in Asia has been less investigated. By comparing the 2014 and 2018 waves of the national survey in Taiwan, we aimed to examine the gender differences in population trends in past-month alcohol use, binge drinking, and harmful alcohol use. METHODS: The national survey enrolled 17,837 participants in 2014 and 18,626 participants in 2018. Binge drinking was defined as having ≥5 drinks on one occasion in the past month, and harmful alcohol use as having an Alcohol Use Disorders Identification Test score of ≥8. RESULTS: There were significant decreases from 2014 to 2018 in the population's prevalence of past-month alcohol use, binge drinking, and harmful alcohol use. However, males and females had different trends: males showed significant reductions in all three alcohol use behaviours (a decrease of 3.79%, 1.59%, and 2.60%, respectively), while females exhibited a significant rise in harmful alcohol use (from 1.32% to 1.72%), particularly among those aged 18-29 years. CONCLUSION: There was gender convergence in alcohol use in Taiwan, mainly due to men's decrease and women's increase in harmful alcohol use. Our findings have important implications for the intervention and prevention of the problematic use of alcohol in East Asia.

Parents' right strategy on preventing youngsters' recent suicidal ideation: a 13-year prospective cohort study.

BACKGROUND: Suicide remains the second leading cause of death among youths. Family-related factors are considered important determinants of children's suicidal ideation, whereas their short-/long-term influence is seldom quantified. AIMS: We aim to confirm the simultaneous/lagged effects of family-related factors on the occurrence of recent suicidal ideation from childhood to young adulthood (aged from 10 to 22 years old). METHOD: Data were derived from a longitudinal prospective cohort study. Participants included 2065 students who were followed up for 13 years. Generalized estimating equations were used to clarify the influential effects of family-related factors on suicidal ideation during the past month. RESULTS: The peak of the rate of recent suicidal ideation arrived during junior high school years. Family interaction, family support, family involvement, and parental punishment had simultaneous effects on recent suicidal ideation. Family involvement, parental conflict, and psychological control had lagged and lasting effects on suicidal ideation. Notably, the lasting protective effects of family involvement were more obvious than simultaneous effects. CONCLUSIONS: Providing parents with sustained support and education to improve their "positive parenting literacy" can help with their children's mental health development. This is especially the case during COVID-19 quarantine periods when families spend the most time together at home.

Relationships of excessive internet use with depression, anxiety, and sleep quality among high school students in northern Vietnam.

PURPOSE: To examine the associations of excessive internet use with depression, anxiety, and sleep quality among high school students in northern Vietnam, a country experiencing rapid economic growth. DESIGN AND METHODS: A cross-sectional study was conducted in a high school in northern Vietnam from July to September 2019. Symptoms of depression and anxiety were respectively assessed using the Center for Epidemiological Studies Depression Scale and the Vietnamese Anxiety Scale. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Internet use and demographic characteristics were obtained using structured questionnaires. A multiple logistic regression was performed. RESULTS: In total, 678 participants with an average age of 16.1 (standard deviation 0.9) years were included. Nearly one-third of the adolescents (30.7%) exhibited excessive internet use (> 4 h/day), 19.6% experienced depressive symptoms, 14.5% presented anxiety symptoms, and 58.8% reported poor sleep quality. Compared to non-excessive internet users, excessive internet users (> 4 h/day) experienced significantly higher levels of depressive symptoms (p = .001), anxiety (p = .008), and poorer sleep quality (p < .001). Students who were female and with fair/poor self-rated health experienced higher depression, anxiety, and poor sleep quality (p < .05). After adjusting for demographic and health-related factors, students with excessive internet use were 58% more likely to experience poor sleep quality (odds ratio, 1.58, 95% confidence interval [1.06, 2.35]). CONCLUSIONS: Excessive internet use in Vietnamese high school students was significantly associated with poor sleep quality, but not with depression or anxiety.

A Comparative Prevalence of Birth Defects between Newborns of Immigrant and Native-Born Mothers in Taiwan: Ten Years of Population-Based Data.

In recent years, newborns born to immigrant mothers have accounted for about 10% of the total births in Taiwan. However, little is known about whether there are differences between newborns of immigrant and native-born mothers regarding the prevalence and the possible causes of birth defects. By combining four nationwide databases and assessing all newborns between 2005 and 2014 in Taiwan as research subjects, this study determined the prevalence of birth defects stratified into nine categories (neuronal, facial, cleft, circulatory, respiratory, digestive, urogenital, musculoskeletal and chromosomal abnormalities) in the newborns of immigrant mothers and native-born mothers. We found that the prevalence of any birth defects in newborns of immigrant mothers (ranging from 0.98 to 1.24%) was lower than that of native-born mothers (2.86%). Skeletomuscular system defects are the most common among newborns of women from the main immigrant countries (0.24-0.42%), while circulatory system defects were the most common among newborns of Taiwanese women (0.92%). The risks of all defects remained lower for newborns of immigrant mothers (AORs ranged from 0.37 to 0.47) after controlling for possible confounding variables. The higher rates of birth defects among newborns of native-born mothers may be attributed to an older maternal age at childbirth and a higher prevalence of diabetes than that of immigrant mothers. The findings from this study imply that the prevalence of birth defects between newborns of immigrant and native-born mothers is not similar, as evidenced by a decade of population-based data.

Association between hypertension and coffee drinking based on CYP1A2 rs762551 single nucleotide polymorphism in Taiwanese.

BACKGROUND: Hypertension increases the likelihood of cardiovascular diseases (CVDs). Cytochrome P450 1A2 (CYP1A2) single nucleotide polymorphism (SNP) is related to caffeine metabolism and the risk of CVD among coffee drinkers. CYP1A2 rs762551 influenced the risk of stroke among hypertensive patients. We examined the relationship between hypertension and coffee drinking based on CYP1A2 rs762551 SNP in Taiwanese adults. METHODS: We used data contained in the Taiwan Biobank database (2011-2018) and included 19,133 participants having complete information on hypertension, rs762551 polymorphism, coffee intake, etc. The risk of hypertension was determined using multiple logistic regression. RESULTS: Coffee intake was significantly associated with a lower risk of hypertension. The odds ratio (OR), 95% confidence interval (CI), and p-value were 0.877, 0.807-0.954, and 0.0032, respectively. CYP1A2 rs762551 was not significantly associated with the risk of hypertension, but it had a significant interactive association with coffee drinking (p value = 0.0303). After stratification by rs762551 genotypes, the inverse coffee drinking-hypertension association was retained, but significant results were observed only in those with the AC + CC genotype (OR 0.678, 95% CI 0.722-900, p value = 0.0001). According to the combination of coffee drinking and rs762551 genotypes (reference group: no coffee drinking and rs762551 AA), the coffee drinking-AC + CC group had a lower risk of hypertension (OR 0.888, 95% CI 0.789-0.999, p value = 0.0483). CONCLUSION: Coffee drinking, particularly among individuals with the CYP1A2 rs762551 AC + CC genotype was associated with lower odds of hypertension.

Is Brisk Walking an Effective Physical Activity for promoting Taiwanese Adolescents' Mental Health?

PURPOSE: The aim of the study was to examine if brisk walking is an effective physical activity for promoting adolescents' mental health. DESIGN AND METHODS: This quasi-experimental study employs a one-group repeated-measure design. Sixty-four volunteer students in 10th to 12th grade were recruited from a high school in central Taiwan, and they participated in a brisk-walking program for 12 weeks. Psychological functioning was measured by self-concept, anxiety, and depression scores (Beck Youth Inventories-Second Edition; BYI-II). Measurements were conducted at baseline, and 4, 10 and 16 weeks after baseline. The effects of the program were analyzed using generalized estimating equations (GEE). RESULTS: Significant decreases were seen in anxiety and depression and an increase in positive self-concept. The effect of physical activity on anxiety was clear and could be observed after 6 weeks of the brisk-walking program. Brisk walking for 30-, 60-, and 90-min sessions was examined, with the 60-min session proving more effective than shorter or longer sessions. CONCLUSIONS: The results suggest that a 12-week brisk-walking program may be effective both at decreasing depression and anxiety and at improving self-concept. The study also showed that anxiety could be considered a risk factor for depression. Further, self-concept was found to be a mediator acting on the psychosocial mechanism of physical activity promoting mental health in adolescents. PRACTICE IMPLICATIONS: While most physical activity programs in past studies combined different activities, the present study demonstrated that brisk walking alone is a simple, effective exercise regime that promotes adolescents' mental health.

A pathway to negative acculturation: marital maladjustment mediates the relationship between the length of residency and depressive symptoms in immigrant women in Taiwan.

BACKGROUND: Immigrant women in Taiwan experience a variety of acculturative and marital problems that result in a mental-health problems. We examined the mediational effect of marital adjustment on the relationship between acculturation and depressive symptoms in immigrant women in Taiwan. METHODS: All participants (N = 127) were interviewed to collect data regarding their basic sociodemographics, depressive symptoms, acculturation (using language proficiency and years in Taiwan as indicators), and marital adjustment. We used a Sobel test to examine how marital adjustment mediates the relationship between acculturation and depressive symptoms. RESULTS: Our results indicated that an increased length of residency exacerbated depressive symptoms (ß = 0.62, p = 0.03) and that this relationship contributed, in part, to the mediational effect of marital adjustment. That is, marital adjustment deteriorated with the length of residency (ß = - 0.26, p = 0.0013), resulting in the development of depressive symptoms (ß = - 0.95, p = 0.0013). CONCLUSION: Although the duration of residency may be useful as a proxy for acculturation in the assessment of some health outcomes, our findings imply that it is better to conceptualize it as a cumulative stress when considering the mental health of immigrant women. Marital maladjustment acts as a mediator in this relationship. As such, it is important to provide immigrant families with programs and resources to assist them in adapting to their marriages and to improve the mental health of immigrant women.

Protective equipment and health education program could benefit students from dust pollution.

In recent years, children living in the downstream of the Choshui River in Taiwan have been exposed to violent dust episodes. For the sake of the health of these children, we aimed to investigate the effectiveness of protective equipment (sand-proof plastic cover and air purifier) installed outside/inside the classrooms on students' pulmonary function and evaluate the health education program for preventing the adverse consequences of exposure to river-dust episodes. Public elementary school students in Yunlin County, which was severely affected by river-dust, were selected as the participants. Study 1 consisted of three-wave follow-up data (801 person-times) in high-/low-dust exposure regions to examine pulmonary function. Study 2 used 147 and 73 students in the high-/low-dust exposure regions, respectively, to establish our health education intervention. Paired t tests, repeated measures ANOVA, and generalized estimating equation were used to analyze the short- and long-term effects. The results showed that the students' pulmonary function in schools that installed protective equipment was improved. The health education (such as the usage of correct masks and our designed PM2.5 full-cover sand-proof clothing) improved the students' cognition and behaviors related to river-dust episodes and yielded both short- and long-term effects. Therefore, we suggest more schools with high-dust exposure to adopt protective equipment and health education program. Our designed PM2.5 full-cover sand-proof clothing can prevent from not only haze but also droplet transmission by infectious diseases such as COVID-19.

Hepatitis B virus seroprevalence among HIV-infected patients receiving combination antiretroviral therapy three decades after universal neonatal hepatitis B immunization program in Taiwan.

BACKGROUND/PURPOSE: This multicenter study aimed to evaluate the seroprevalence of hepatitis B virus (HBV) and the use of combination antiretroviral therapy (cART) among patients receiving HIV care in Taiwan. METHODS: We retrospectively reviewed the medical records of HIV-infected adult patients who initiated cART at 11 designated hospitals in Taiwan between 2012 and 2016. The clinical information collected included serological profiles on HBV, hepatitis C virus (HCV), and syphilis, plasma HIV RNA load, nadir CD4 cell count, and antiretrovirals with activity against both HBV and HIV (tenofovir disoproxil fumarate [TDF], lamivudine [LAM], and emtricitabine [FTC]). RESULTS: We analyzed 1800 HIV-infected patients; 1742 (96.8%) were male and 794 (44.1%) were born after July, 1986, when nationwide universal neonatal HBV vaccination was implemented. HBsAg positive results were 11.6% (209/1800), which decreased significantly from 18.1% (182/1006) in those born before July 1986 to 3.4% (27/794) in those born after. In multivariable analysis, HBsAg positivity was significantly associated with age (adjusted odds ratio [aOR] 1.06, 95% confidence interval [CI] 1.05-1.08), CD4≧200 cells/µL (aOR 0.73, 95% CI 0.53-0.99), and HCV seropositivity (aOR 1.62, 95% CI 1.06-2.50). Of 209 HBV/HIV-coinfected patients, 31.1% started cART containing only LAM with anti-HBV activity, while 68.9% started cART containing TDF plus LAM or coformulated TDF/FTC. CONCLUSIONS: The overall prevalence of HBV/HIV coinfection remained high among HIV-infected patients in Taiwan. Despite recommendations of the HIV treatment guidelines for the management of HBV infection, a substantial proportion of HIV/HBV-coinfected patients received cART containing only LAM for HBV infection.

Factors associated with hepatitis A virus infection among HIV-positive patients before and after implementation of a hepatitis A virus vaccination program at a medical centre in central Taiwan.

Background Taiwan government has promoted the administration of a hepatitis A vaccine at public expense for high-risk groups as a preventive measure after the outbreak of hepatitis A virus (HAV) infections in 2015. The aim of this study was to evaluate the efficacy of such vaccination policy in patients with human immunodeficiency virus (HIV). METHODS: From January 2016 to July 2017, we enrolled 658 HIV-positive male participants. Participants were stratified into anti-HAV-positive (n = 165) and anti-HAV-negative (n = 493) groups. A total of 364 anti-HAV-negative patients received vaccination against HAV and were followed up for 1.5 years. A Cox regression model was used to estimate the effects of factors predicting positive anti-HAV detection after vaccination. RESULTS: Patients with HIV had an anti-HAV-positive prevalence of 25.1% before vaccination. Of the 364 patients inoculated with the first dose of vaccine, 58.0% received the second dose. Seroresponse rates were 50.0% and 80.6%, respectively. Antibody production was 30.0% lower in patients with a CD4 T-cell count <200 cells/µL (adjusted relative risk (ARR) = 0.7; 95% confidence interval (CI) = 0.5-0.9) compared with those with 500 cells/µL. Hepatitis C co-infection reduced the production of antibodies by 50.0% (ARR = 0.5; 95% CI = 0.2-0.8). CONCLUSION: This study suggests that vaccination against hepatitis A be administered when the immunity of an HIV-positive patient is strong. The promotion of the current vaccination policy against hepatitis A in Taiwan has improved the vaccination rate; the response rate for receiving one dose of the vaccine doubled.

Effectiveness of a brief information, motivation and behavioral skills program on stage transitions and lapse for individuals who use ketamine.

OBJECTIVE: Chronic ketamine use is a significant public health and social problem in East and South East Asia and may lead to impairments in health and cognitive functioning. The study evaluated effects of an information, motivation and behavior skills (IMB) program on changes in motivational stage and ketamine use. METHODS: Ketamine using individuals residing in the City of Taipei were recruited (N = 395): 279 selected an IMB program consisting of a 1-day workshop of six 50-minute interactive sessions provided in small groups. The remaining 116 participants selected an education-as-usual (EAU) program consisting of a 1-day workshop of six 50-minute didactic lectures provided in a large group format. Motivational stage of change and ketamine knowledge were assessed before and after the interventions. Participants were followed one year later to assess their ketamine use status. RESULTS: No significant difference in knowledge increase between the IMB and EAU groups (p = .59). The proportion of participants who transitioned from the contemplation to preparation motivational stages was greater in the IMB group than in the EAU group (p < .01). A significant difference in the rates of ketamine lapse during a one-year post intervention follow up was observed between the IMB (50%) and EAU (75%) groups (p < .01). CONCLUSIONS: Interventions based on IMB principles may be more effective in supporting motivational stage transition and in prevention of lapses to ketamine use as compared to currently offered standard drug education programs. Policy makers should consider including IMB interventions in their rehabilitation programs addressing ketamine use problems.

Nonmedical prescription drug use of analgesics and sedatives/hypnotics in Taiwan: Results from the 2014 National Survey of Substance Use.

Nonmedical prescription drug use (NMPDU) has become a major public health issue but little is known in Asian populations. This study aimed to investigate the prevalence and correlates of NMPDU in Taiwan. Participants from the 2014 national survey of 17,837 individuals, aged 12 to 64 year, completed anonymously a computer-assisted self-interview. Past-year prescription drug use was divided into medical use only (MUO) and nonmedical use (NMU), defined as using the drug without a prescription, or more frequently, or in larger doses than prescribed. Problematic alcohol use was measured using the Alcohol Use Disorders Identification Test (AUDIT), problematic drug use using the 20-item Drug Abuse Screening Test (DAST), and depressive symptoms using the Center for Epidemiological Study-Depression (CES-D). The prevalence of past-year NMU was 3.02% for analgesics, 0.71% for sedatives/hypnotics, and 3.66% for either drug, with a very small overlap of NMU between analgesics and sedatives/hypnotics (0.07%). When individuals with NMU were compared to those without NMU (Non-NMU) and those with MUO, respectively, some correlates consistently identified, including young adulthood, tobacco smoking, alcohol drinking, and greater AUDIT's scores for analgesics, as well as hard drug use and greater DAST's scores for sedatives/hypnotics. NMU was associated with greater CES-D's scores for both analgesics and sedatives/hypnotics when compared to Non-NMU but not to MUO. Robust correlates of NMPDU could offer implications for development of prevention strategies of NMPDU.
