Validation of the Chinese Version of Penn Alcohol Craving Scale for Patients With Alcohol Use Disorder.

OBJECTIVE: The Penn Alcohol Craving Scale (PACS) is a five-item, single-dimension questionnaire that is used to measure a patient's alcohol craving. We sought to develop the Chinese version of the PACS (PACS-C) and assess its reliability and validity. METHODS: A total of 160 Taiwanese patients with alcohol use disorder were enrolled in this study. The internal consistency and concurrent validity of the PASC-C with the visual analogue scale (VAS) for craving, the Yale-Brown Obsessive Compulsive Scale for heavy drinking (YBOCS-hd), and the Severity of Alcohol Dependence Questionnaire (SADQ) were assessed. The test-retest reliability of the PASC-C was evaluated 1 day after the baseline measurements. Confirmatory factor analysis (CFA) was performed to examine the psychometric properties of the PACS-C. RESULTS: The PACS-C exhibited good internal consistency (Cronbach's α=0.95) and test-retest reliability (r=0.97). This scale showed high correlations with the VAS (r=0.81) and YBOCS-hd (r=0.81 and 0.79 for the obsession and compulsion subscales, respectively), and moderate correlation with the SADQ-C (r=0.47). Furthermore, CFA results revealed that the PACS-C had good fit indices under various models. CONCLUSION: The PACS-C appears to be a reliable and valid tool for assessing alcohol craving in patients with alcohol use disorder in Taiwan.

Effectiveness of Cold Therapy for Pain and Anxiety Associated with Chest Tube Removal: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.

OBJECTIVES: To assess the effectiveness of cold therapy for pain and anxiety associated with chest tube removal. DESIGN: A Systematic review and meta-analysis of randomized controlled trials. DATA SOURCES: Articles were searched from Cochrane Library, PubMed, Embase, CINAHL, ProQuest, Airiti Library, China National Knowledge Infrastructure, and the National Digital Library of Theses and Dissertations in Taiwan. REVIEW/ANALYSIS METHODS: Eight electronic databases were searched from inception to August 20, 2022. The Cochrane Risk of Bias 2.0 tool was used to assess the quality of the included studies. Using a random-effects model, we calculated Hedges' g and its associated confidence interval to evaluate the effects of cold therapy. Cochrane's Q test and an I2 test were used to detect heterogeneity, and moderator and meta-regression analyses were conducted to explore possible sources of heterogeneity. Publication bias was assessed using a funnel plot, Egger's test, and trim-and-fill analysis. RESULTS: We examined 24 trials involving 1,821 patients. Cold therapy significantly reduced pain during and after chest tube removal as well as anxiety after chest tube removal (Hedges' g: -1.28, -1.27, and -1.80, respectively). Additionally, the effect size of cold therapy for reducing anxiety after chest tube removal was significantly and positively associated with that of cold therapy for reducing pain after chest tube removal. CONCLUSIONS: Cold therapy can reduce pain and anxiety associated with chest tube removal.

Quality of life and associated factors of heroin-dependent patients receiving methadone and buprenorphine maintenance treatment.

AIM: Although studies in Western countries have investigated the quality of life (QoL) of heroin users, limited research on this topic has been conducted in Asia. The present study assessed QoL in patients with heroin dependence receiving medications to treat opioid use disorder. METHODS: We performed a cross-sectional study of patients with heroin dependence receiving methadone and buprenorphine treatment. The demographic and substance use variables of patients receiving methadone and buprenorphine were compared. The Chinese Health Questionnaire (CHQ-12), Obsessive Compulsive Drug Use Scale (OCDUS), and World Health Organization Quality of Life Short Form Taiwan version (WHOQOL-BREF-T) were administered to measure patient mental health problems, addiction severity, and QoL, respectively. Multivariate regression was used to identify the factors associated with QoL. RESULTS: A total of 149 patients receiving methadone and 31 receiving buprenorphine completed the questionnaires. Individuals in the buprenorphine group were more likely to be married (p = 0.024) or employed (p = 0.024), have a higher educational level (p = 0.013), have lower drug craving (OCDUS: p = 0.035), or have higher QoL (WHOQOL-BREF-T: p = 0.004) than those in the methadone group. After adjustment for other variables, employment was positively associated with the physical, psychological, and environmental domains of QoL. Receiving buprenorphine treatment (p = 0.032) and longer treatment duration (p = 0.016) were associated with higher psychological QoL. CONCLUSION: Several factors were associated with QoL in patients with heroin dependence. Some measures may improve their QoL, such as reducing employment barriers, improving treatment adherence, or increasing accessibility to buprenorphine treatment.

A smartphone-based support system coupled with a bluetooth breathalyzer in the treatment of alcohol dependence: A 12-week randomized controlled trial.

Background: Our prior open trial showed the feasibility of a smartphone-based support system coupled with a Bluetooth breathalyzer (SoberDiary) in assisting recovery for patients with alcohol dependence (AD). In this 24-week follow-up study, we further explored the efficacy of supplementing SoberDiary to treatment as usual (TAU) over 12 weeks of intervention and whether the efficacy persisted in the post-intervention 12 weeks. Methods: 51 patients who met the DSM-IV criteria of AD were randomly assigned to the technological intervention group (TI group, receiving technology intervention of SoberDiary plus TAU, n = 25) or those receiving only TAU (TAU group, n = 26). After 12 weeks of intervention (Phase I), all participants were followed for another post-intervention 12 weeks (Phase II). We collected the drinking variables and psychological assessment data every 4 weeks (i.e., weeks 4, 8, 12, 16, 20, and 24). In addition, the cumulative abstinence days and retention rates were recorded. We used mixed-model analysis to compare the difference in outcomes between groups. Results: In Phase I or Phase II, we did not find differences in drinking variables, alcohol craving, depression, or anxiety severity between the two groups. However, the TI group showed greater self-efficacy for drinking refusal in Phase II than the TAU group. Conclusions: Although our system (SoberDiary) did not demonstrate benefits in drinking or emotional outcomes, we found the system holds promise to enhance self-efficacy on drinking refusal. Whether the benefit in promoting self-efficacy persists longer than 24 weeks requires further investigation.

Effects of video-recorded role-play and guided reflection on nursing student empathy, caring behavior and competence: A two-group pretest-posttest study.

AIM: The study examined the differences in nursing student empathy, caring behavior and competence between the experimental and control groups before and after educational intervention and to predict the factors affecting their core competencies. BACKGROUND: Educating nursing students in empathy and caring behaviors before entering clinical practice is challenging. DESIGN: We used a two-group pretest and post-test quasi-experimental design. METHODS: First-year nursing students from medical schools in Taiwan participated in our study. Data were collected between March and May 2022. The learning method used with the intervention group was role-playing with videos and guided reflection. The control group was exposed to traditional curriculum. Empathy, caring behavior and competence were measured using the Jefferson Scale of Empathy- Healthcare Providers, the Caring Behaviors Scale and the Nursing Student Competence Scale. RESULT: A total of 72 participants (40 in the experimental group and 32 in the control group) were included in the final statistical analysis. The response rate was 92%. Statistically significant differences in nursing student empathy, caring behavior and competence were observed between the experimental and control groups (p < .05). The η2 effect levels were 0.083, 0.223 and 0.270. Higher caring behavior scores were significantly associated with higher nursing student competence scores (ß = 0.81, 95% CI:0.66-0.97). CONCLUSIONS: Education based on video role-play and guided reflection improved empathy, caring behavior and nursing competence in first-year nursing students.

Risk factors for relapse among methamphetamine users receiving a joint legal-medical treatment program as a diversion intervention: A one-year follow-up study.

BACKGROUND: Methamphetamine (METH) is a Schedule II illicit drug in Taiwan. A 12-month legal-medical joint intervention program has been developed for first-time METH offenders during deferred prosecution. Risk factors associated with METH relapse use among these individuals were unknown. METHODS: We enrolled a total of 449 METH offenders referred by the Taipei District Prosecutor's Office to Taipei City Psychiatric Center. The study defines relapse as having any positive urine toxicology result or self-report of METH use during 12-month treatment. We compared demographic and clinical variables between a relapse group and nonrelapse group and used a Cox proportional hazards model to determine variables associated with time to relapse. RESULTS: Of all participants, 37.8 % relapsed to use METH and 23.2 % were noncompleters in the one-year follow-up. Compared to the nonrelapse group, the relapse group had lower educational attainment, more severe psychological symptoms, longer duration of METH use, higher odds of polysubstance use, higher craving severity, and higher odds of positive baseline urine. The Cox analysis revealed individuals with positive urine results and higher craving severity at baseline were at higher risks of METH relapse (hazard ratio [95 % CI]: 3.85 [2.61-5.68] and 1.71 [1.19-2.46], respectively, p < 0.001). Baseline positive urine results and high craving could also predict a shorter length of time to relapse than their respective counterparts. CONCLUSIONS: Positive urine screening for METH at baseline and high craving severity are two indicators of an increased risk of drug relapse. Tailored treatment plans incorporating these findings to prevent relapse are warranted in our joint intervention program.

Change of home visit frequency by public health nurses predicts emergency escorts for psychiatric patients living in the community: A retrospective medical record review.

Background: Improper or insufficient treatment of mental health illness harms individuals, families, and society. When psychiatric treatment shifts from a hospital-based to a community-based health care system, risk management is essential to the provision of effective care. Objective: We examine whether an upgrade in home visit frequency of psychiatric patients as identified by public health nurses can predict the subsequent need for emergency escort services for medical treatment. Design: A 2-year retrospective medical record review. Settings: A district of New Taipei City in Taiwan. Participants: A total of 425 patients with a diagnosed mental health illness cared for through home visits by public health nurses from January 2018 to December 2019. Methods: We accessed the Ministry of Health and Welfare's psychiatric care management information system to identify a set of medical records, and analyzed these records using chi-square and regression analyses. Results: The analyses indicated that the groups experiencing the greatest need for emergency escort services were: male, 35-49 years old, with a senior high school level of education, without a disability identification card, with a schizophrenia diagnosis, and had been reported by the nurse as having progressed to a serious level. Nurses' increased frequency of home visits (an indicator that the patient's overall condition was worsening) and nurses' reports of increased severity of problems were significant predictors of the need for emergency escort services. Conclusions: The nurses' adjustment of visit frequency based on the results of the visit assessment predicts the need for emergency escort services for mental patients. The findings support not only the professional roles and functions of public health nurses, but also the importance of strengthening psychiatric health community support services.

The Effect of Physical Activity on Body Constitution and Psychological Health in Older Adults: Evidence From an Analysis of a Biobank Research Database.

This study aims to describe the relationship between physical activity, suboptimal health status based on traditional Chinese medicine, and psychological health in older people in Taiwan. A total of 4,497 older individuals were selected from the Taiwan Biobank Research Database. Suboptimal health status was assessed using a body constitution questionnaire to measure yang deficiency, yin deficiency, and stasis. The results showed that older adults involved in physical activity had a lower likelihood of yang/yin deficiency and stasis constitutions than physically inactive people. Participants with yang deficiency or stasis constitutions had a higher likelihood of poor psychological health, whereas those with yin deficiency had a greater likelihood of depression. People involved in physical activity had a lower likelihood of depression than physically inactive people. Compared with male older adults, females had a lower percentage of physical activity habits, poorer body constitutions, and poorer psychological health.

Long-term Outcomes of Early Use of Long-Acting Injectable Antipsychotics in Schizophrenia.

Background: Long-acting injectable antipsychotics (LAIs) may potentially benefit patients requiring psychiatric hospitalization during the early stages of schizophrenia. However, few studies have compared the long-term effectiveness between patients who switched to LAIs and those who remained on oral antipsychotics (OAPs).Methods: Using the Taiwan National Health Insurance Research Database, we constructed a population-based cohort with 19,813 new OAP users with ICD-9-CM-defined schizophrenia who were hospitalized from 2002 to 2005. Within this cohort, 678 patients who switched to LAIs during their hospitalization were identified. The LAI group was matched to patients who remained on OAPs (n = 678). The LAI cohort was further subdivided for analysis into patients who switched to LAIs within 3 years of OAP initiation ("an early stage") and those who switched after 3 years ("a late stage"). Conditional Cox regressions and conditional negative binomial regressions were used to estimate the risk of death and the number of hospital visits between the two groups.Results: During the 13-year study period, 312 patients switched to LAIs within the first 3 years of OAP initiation. All- and natural-cause mortalities in these patients were significantly lower than in those who remained on OAPs. The hazard ratios (HRs) for all- and natural-cause mortalities were 0.49 (95% confidence interval [CI], 0.27-0.87) and 0.30 (95% CI, 0.15-0.60), respectively. No significant decrease associated with LAIs was observed in unnatural-cause mortality. Patients receiving LAIs had lower risks of rehospitalization (incidence rate ratio [IRR] = 0.56, 95% CI, 0.45-0.69), psychiatric hospitalization (IRR = 0.63, 95% CI, 0.50-0.81), and psychiatric emergency room visits (IRR = 0.58, 95% CI, 0.45-0.75) compared to patients who remained on OAPs. Use of LAIs in the late stage of treatment did not decrease the risk of relapse or mortality.Conclusions: Switching to LAIs during the first 3 years of treatment improved antipsychotic adherence, decreased relapses, and reduced long-term mortality. Our results provide evidence to support the benefits of early LAI treatment in schizophrenia.

Psychometric evaluation of a nursing competence assessment tool among nursing students: a development and validation study.

BACKGROUND: Nursing competence refers to the core abilities that are required for fulfilling one's role as a nurse. A specific instrument comprehensively measuring competence among nursing students has not yet been developed. The purpose of the study was to develop and validate a nursing competence instrument for nursing students in bachelor training. METHODS: A descriptive and explorative study design was used. Data were collected from students at one medical college in Taiwan in 2020 and 2021. A total of 241 nursing students participated in this study. We developed the initial instrument through systematic review, expert evaluations, and pilot versions. Its validity was then tested using confirmatory factor analysis (CFA) and criterion-related validity, while its reliability was tested using Cronbach's alpha and test-retest analysis. RESULTS: The final fit indexes of CFA were as follows: chi-square = 860.1 (p < 0.01), normed chi-square = 2.24, SRMR = 0.04, RMSEA = 0.07, CFI = 0.94, and TLI = 0.94. Cronbach's alpha values for the subscales observed ranged from 0.91 to 0.98. The test-retest reliability coefficient for the Nurse Competence Scale was 0.515 (n = 30, p < 0.01). CONCLUSIONS: The instrument exhibited acceptable psychometric properties, thereby proving itself a valuable tool for evaluating nursing students' competence at bachelor training. Further assessments of its reliability, validity, and generality from mentors' and scholars' views in different contexts and cultures are recommended.

Orexin-a elevation in antipsychotic-treated compared to drug-free patients with schizophrenia: A medication effect independent of metabolic syndrome.

BACKGROUND/PURPOSE: Orexin-A levels are reportedly increased in antipsychotic (APD)-treated patients with schizophrenia compared to healthy controls and have been associated with metabolic abnormalities. It is not clear whether the orexin-A elevation is related specifically to the drug (APDs) effect, which should be clarified by including a drug-free group for comparison, or related to drug-induced metabolic abnormalities. METHODS: Blood orexin-A levels and metabolic profiles were compared between 37 drug-free, 45 aripiprazole-treated, and 156 clozapine-treated patients with schizophrenia. The association between orexin-A and metabolic outcomes were examined. We explored the effects of APDs treatment and metabolic status on orexin-A levels by linear regression. RESULTS: Patients under APDs treatment had increased orexin-A levels compared to drug-free patients, with aripiprazole-treated group having higher orexin-A levels than clozapine-treated group. Higher orexin-A levels reduced the risks of metabolic syndrome (MS) and type 2 diabetes mellitus, indicating a relationship between orexin-A levels and metabolic problems. After adjusting the effect from metabolic problems, we found APD treatment is still associated with orexin-A regulation, with aripiprazole more significantly than clozapine. CONCLUSION: With the inclusion of drug-free patients rather than healthy controls for comparison, we demonstrated that orexin-A is upregulated following APD treatment even after we controlled the potential effect from MS, suggesting an independent effect of APDs on orexin-A levels. Furthermore, the effect differed between APDs with dissimilar obesogenicity, i.e. less obesogenicity likely associated with higher orexin-A levels. Future prospective studies exploring the causal relationship between APDs treatment and orexin-A elevation as well as the underlying mechanisms are warranted.

Exploring the mediating role of methamphetamine use in the relationship between adverse childhood experiences and attempted suicide.

OBJECTIVE: Methamphetamine (METH) use and adverse childhood experiences (ACEs) has been associated with an increased risk of suicidal behaviour. However, whether METH use underlies the risk of suicide attributable to ACEs is unknown and warrants investigation to inform preventive interventions. In this study, we examined the mediating role of METH use in the relationship between attempted suicide and ACEs. METHOD: METH users recruited from a mandatory detoxification center (n = 346) and healthy controls (n = 342) both completed a survey related to 9 types of ACE, which was based the Family Health Questionnaire. A lifetime history of attempted suicide was obtained using the Chinese version of the Composite International Diagnostic Interview. We conducted a bootstrapped mediation analysis to examine the mediating effect of METH use on the association between ACEs and attempted suicide. RESULTS: Female gender, METH use, and having multiple (≥3) ACEs were associated with an increased risk of attempted suicide. A dose-response relationship between the number of ACEs and suicide rate was observed among individuals with METH use. METH use significantly mediated the association between ACEs and attempted suicide in those with multiple (2 and 3 ACEs respectively with proportion mediated 0.16 and 0.42) and specific types of ACEs (physical abuse, witnessing maternal battering, household substance abuse, sexual abuse, and parental separation with proportion mediated 0.25, 0.35, 0.38, 0.48, 0.47 respectively). CONCLUSION: Our study is the first to demonstrate that METH use partially mediates the association between ACEs and attempted suicide. Addressing METH use in people with ACEs could reduce their suicide risk.

Examining factors associated with postintervention recidivism in DUI repeat offenders after alcohol treatment: One-year follow-up study.

Taiwan has deemed driving under the influence of alcohol (DUI) to be criminal, and offenders are subjected to fines and jail penalties without being offered alcohol-related treatment, although alcohol use problems are prevalent in this population. We followed the recidivism records of DUI repeat offenders for one year after they had received a newly established legal-medical joint intervention program for alcohol treatment and examined factors related to postintervention recidivism. In this study, 231 DUI repeat offenders with alcohol use problems screened out by the Alcohol Use Disorder Identification Test were referred from the prosecutors' office to one psychiatric hospital for SBIRT-based alcohol treatment. We divided the participants into two groups based on the official recidivism records within the year following the end of treatment. The study used a Cox proportional hazards model to examine the hazard ratio of the baseline clinical characteristics and intervention duration for post-treatment recidivism. The study used generalized estimation equation models to examine changes in psychological symptoms and drinking behaviors over time. We found that participants who recidivated in the next year after intervention did not differ from those without recidivism records in all measurements except for the length of duration they stayed in treatment. Survival analysis determined that participants who had received the intervention for >4 months showed significantly lower rates of one-year postintervention recidivism rates The study participants showed improved psychological symptoms and drinking behaviors during the follow-up period. In conclusion, adequate duration of alcohol treatment is a significant factor associated with a lower risk of postintervention recidivism. The results provide some insight into the design of a collaborative program between legal and medical systems to reduce DUI recidivism and improve mental health of DUI repeat offenders.

Comparison of Long-Acting Injectable Antipsychotics With Oral Antipsychotics and Suicide and All-Cause Mortality in Patients With Newly Diagnosed Schizophrenia.

Importance: Schizophrenia is generally considered to be among the most severe psychiatric disorders because of the excessive mortality associated with it. Research to find means to reduce this excessive mortality is warranted. Objective: To investigate associations of long-acting injectable antipsychotics (LAIs) with all-cause, natural-cause, and suicide mortality risks as well as the impacts of early use of LAIs in patients with newly diagnosed schizophrenia. Design, Setting, and Participants: This cohort study used data from the Taiwan National Health Insurance Research Database to construct a population-based cohort of patients with schizophrenia who received oral antipsychotics (OAPs) from January 1, 2002, to December 31, 2017. Within this cohort, the LAI group was defined as patients who switched to LAIs and were prescribed LAIs at least 4 times within 1 year. The LAI group was propensity matched 1:1 to patients who continued receiving OAPs of the same compounds. All patients were followed up until switching the antipsychotic administration route, death, or the end of the study (December 31, 2018), whichever occurred first. Data analysis was performed from January 2002 to December 2018. Main Outcomes and Measures: All-cause mortality, natural-cause mortality, suicide mortality, and suicide attempts. Results: In total, 2614 patients who switched to LAIs (median [interquartile range] {IQR} age, 30 [23-39] years) and 2614 who received OAPs (median [IQR] age, 30 [23-39] years) were included (1333 male patients [51.0%] in each group). During the 16-year follow-up period (median [IQR] follow-up of 14 [10-17] years), patients who switched to LAIs had lower risks of all-cause mortality (adjusted hazard ratio [aHR], 0.66; 95% CI, 0.54-0.81), natural-cause mortality (aHR, 0.63; 95% CI, 0.52-0.76), and suicide attempts (incidence rate ratio, 0.72; 95% CI, 0.55-0.93) compared with patients who received the corresponding OAPs. A 47% lower suicide mortality risk (aHR, 0.53; 95% CI, 0.30-0.92) was observed in patients who switched to LAIs within the first 2 years of OAP initiation. Conclusions and Relevance: These findings suggest that LAI use in patients with newly diagnosed schizophrenia is associated with decreased all-cause mortality and suicide risk. Furthermore, early treatment with LAIs within the first 2 years of OAP initiation was associated with a decrease in suicide mortality risk. Thus, LAI use in the early stage of treatment should be actively considered for patients with newly diagnosed schizophrenia.

Effects of Neurofeedback on Fibromyalgia: A Randomized Controlled Trial.

BACKGROUND: Fibromyalgia is a chronic widespread pain condition that is associated with sleep disturbances and cognitive impairments. Neurofeedback has been demonstrated to improve pain, sleep quality, and fatigue. However, few studies have examined the effect of neurofeedback for patients with fibromyalgia. AIM: To determine the effects of neurofeedback on pain intensity, symptom severity, sleep quality, and cognitive function in patients with fibromyalgia. DESIGN: This study was a randomized controlled trial. METHOD: Eighty participants were randomized to a neurofeedback group (N = 60), receiving sensorimotor and alpha rhythm feedback for 8 weeks, or a telephone support group (N = 20). RESULTS: Results from the generalized estimating equation modelling revealed significant group-by-time interactions for Brief Pain Inventory pain severity (B = -1.35, SE = 0.46, p = .003) and pain interference (B = -1.75, SE = 0.41, p < .001), Revised Fibromyalgia Impact Questionnaire total scores (B = -16.41, SE = 3.76, p < .001), sleep onset latency (B = -25.33, SE = 9.02, p = .005), and Psychomotor Vigilance Test error (B = -1.38, SE = 0.55, p = .013) after adjustments for age, sex, duration of illness, and group differences at baseline. CONCLUSIONS: An 8-week neurofeedback training regimen of sensorimotor rhythm and alpha brain waves significantly improved pain severity and interference, fibromyalgia symptom severity, sleep latency, and sustained attention in patients with fibromyalgia.

Early-onset prostate cancer is associated with increased risks of disease progression and cancer-specific mortality.

OBJECTIVE: Prostate cancer (PCa) incidence has stabilized but not in patients at a young age. We assessed patient characteristics and disease progression in early-onset PCa. METHODS: A retrospective cohort of 28,039 newly diagnosed PCa patients aged ≥35 years was constructed using the Taiwan Cancer Registry in 2008-2016. Patients were categorized by age at diagnosis (≤54, 55-59, 60-69, 70-74, and ≥75 years). The clinical stage at diagnosis, Gleason score, prostate-specific antigen level at diagnosis, Charlson's comorbidity index, and primary and secondary treatments for PCa were included in the analysis. All-cause mortality and prostate cancer-specific mortality (PCSM) were reported. Hazard ratios (HRs) and 95% confidence intervals (CIs) estimating the risks of death and of receiving secondary cancer treatment were generated by Cox hazard models. RESULTS: In patients aged ≤54, 55-59, and 60-69 years, about 60% of them in each group were classified into the high-risk, very high-risk, or metastatic group. However, young patients ≤54 years had a higher risk of PCSM than patients aged 60-69 years (HR = 1.22; 95% CI = 1.10-1.49). This trend of an increased risk in PCSM remained for high-risk, very high-risk, or metastatic patients (HR = 1.24; 95% CI = 1.01-1.51), but not in low- or intermediate-risk patients. Besides, young patients diagnosed with high-risk diseases had the highest risk of receiving secondary cancer treatment within 180 days after completing primary treatment among all age groups (HR = 1.32; 95% CI = 1.07-1.63). CONCLUSIONS: PCa arising in young patients ≤54 years of age, especially those with a high risk or metastatic form, might be more aggressive than that in other age groups.

The effectiveness of long-acting injectable antipsychotics versus oral antipsychotics in the maintenance treatment of outpatients with chronic schizophrenia.

OBJECTIVE: To compare the psychiatric service utilization between patients who only received long-acting injectable antipsychotics (LAIAs) and those who only received oral antipsychotics (OAPs) in the maintenance treatment of chronic schizophrenia. METHODS: We constructed a cohort of chronic schizophrenia patients who underwent maintenance treatment from the Taiwan National Health Insurance Research Database in 2011 and followed these patients for 12 months. We included patients who had been diagnosed with schizophrenia for at least 3 years, were not hospitalized in 2011, and had received 1 year of maintenance treatment. Inverse probability of treatment weighting logistic, linear, and negative binomial regression models were used to estimate associated psychiatric services utilization and adjust for covariate imbalances between the LAIAs and OAPs groups. RESULTS: Among 40,194 patients, 948 (2.36%) received only LAIAs and 39,246 (97.64%) received only OAPs. Compared with those who received only OAPs, the sole LAIAs users were associated with a lower percentage of psychiatric hospitalization (8.4% and 5.8%, respectively; odds ratio: 0.63, p < .01), shorter lengths of hospitalization days (82.8 and 65.9, respectively; coefficient [b]: -16.87, p = .03), and fewer emergency room visits (2.3 and 1.8, respectively; b: -0.24, p < .01) per patient. CONCLUSIONS: Chronic schizophrenia patients who received only LAIs had a lower risk of disease relapse and a reduction in psychiatric service utilization than those receiving only OAPs.

Influence of Baseline Cardiovascular Comorbidities on Mortality after Androgen Deprivation Therapy for Metastatic Prostate Cancer.

Few studies have assessed the benefits of androgen deprivation therapy (ADT) in men with metastatic prostate cancer (PC; mPC) at an old age or with major cardiovascular conditions. A retrospective cohort consisted of 3835 men with newly diagnosed mPC from the Taiwan Cancer Registry of 2008-2014. Among them, 2692 patients received only ADT in the first year after the cancer diagnosis, and 1143 patients were on watchful waiting. The inverse probability of treatment-weighted Cox model was used to estimate the effects of ADT on all-cause mortality and PC-specific mortality according to age, and the status of congestive heart failure (CHF), coronary arterial diseases (CADs), and stroke at the baseline. After a median follow-up of 2.65 years, 1650 men had died. ADT was associated with a 17-22% risk reduction in all-cause and PC-specific mortality in men without stroke, CAD, or CHF in the 65-79-year group. The survival benefit diminished in men with any of these preexisting conditions. In contrast, ADT was not found to be associated with any survival benefit in the ≥80-year group, even though they did not present with any major cardiovascular disease at the baseline. Patients who had CHF, CAD, or stroke at the baseline did not show a survival benefit following ADT in any of the age groups. Men who have preexisting major cardiovascular diseases or are ≥80 years do not demonstrate a survival benefit from ADT for mPC. The risk-benefit ratio should be considered when using ADT for mPC in older men especially those with major cardiovascular comorbidities.

Heart Rate Variability and Risk of All-Cause Death and Cardiovascular Events in Patients With Cardiovascular Disease: A Meta-Analysis of Cohort Studies.

Lower heart rate variability (HRV) is associated with a higher risk of cardiovascular events and mortality, although the extent of the association is uncertain. We performed a meta-analysis of cohort studies to elucidate the association between HRV and the risk of all-cause death or cardiovascular events in patients with cardiovascular disease (CVD) during a follow-up of at least 1 year. We searched four databases (PubMed, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials) and extracted the adjusted hazard ratio (HR) from eligible studies. We included 28 cohort studies involving 3,094 participants in the meta-analysis. Results revealed that lower HRV was associated with a higher risk of all-cause death and cardiovascular events; the pooled HR was 2.27 (95% confidence interval [CI]: 1.72, 3.00) and 1.41 (95% CI: 1.16, 1.72), respectively. In subgroup analyses, the pooled HR of all-cause death was significant for patients with acute myocardial infarction (AMI) but not for those with heart failure. The pooled HR for cardiovascular events was significant for the subgroup of patients with AMI and acute coronary syndrome but not for those with coronary artery disease and heart failure. Additionally, both time and frequency domains of HRV were significantly associated with risk of all-cause death and cardiovascular events in patients with CVD.
