Transcranial direct current stimulation (tDCS) is a promising treatment for major depressive disorder (MDD). This study evaluated its antidepressant and cognitive effects as a safe, effective, home-based therapy for MDD.

This double-blind, sham-controlled, randomized trial divided participants into low-intensity (1 mA, n = 47), high-intensity (2 mA, n = 49), and sham (n = 45) groups, receiving 42 daily tDCS sessions, including weekends and holidays, targeting the dorsolateral prefrontal cortex for 30 minutes. Assessments were conducted at baseline and weeks 2, 4, and 6. The primary outcome was cognitive improvement assessed by changes in total accuracy on the 2-back test from baseline to week 6. Secondary outcomes included changes in depressive symptoms (HAM-D), anxiety (HAM-A), and quality of life (QLES). Adverse events were monitored. This trial was registered with ClinicalTrials.gov (NCT04709952).

In the tDCS study, of 141 participants (102 [72.3%] women; mean age 35.7 years, standard deviation 12.7), 95 completed the trial. Mean changes in the total accuracy scores from baseline to week 6 were compared across the three groups using an F-test. Linear mixed-effects models examined the interaction of group and time. Results showed no significant differences among groups in cognitive or depressive outcomes at week 6. Active groups experienced more mild adverse events compared to sham but had similar rates of severe adverse events and dropout.

Home-based tDCS for MDD demonstrated no evidence of effectiveness but was safe and well-tolerated. Further research is needed to address the technical limitations, evaluate broader cognitive functions, and extend durations to evaluate its therapeutic potential.

Clostridioides difficile infection (CDI) may be misdiagnosed if testing is performed in the absence of signs or symptoms of disease. This study sought to support appropriate testing by estimating the impact of signs, symptoms, and healthcare exposures on pre-test likelihood of CDI.

A panel of fifteen experts in infectious diseases participated in a modified UCLA/RAND Delphi study to estimate likelihood of CDI. Consensus, defined as agreement by >70% of panelists, was assessed via a REDCap survey. Items without consensus were discussed in a virtual meeting followed by a second survey.

All fifteen panelists completed both surveys (100% response rate). In the initial survey, consensus was present on 6 of 15 (40%) items related to risk of CDI. After panel discussion and clarification of questions, consensus (>70% agreement) was reached on all remaining items in the second survey. Antibiotics were identified as the primary risk factor for CDI and grouped into three categories: high-risk (likelihood ratio [LR] 7, 93% agreement among panelists in first survey), low-risk (LR 3, 87% agreement in first survey), and minimal-risk (LR 1, 71% agreement in first survey). Other major factors included new or unexplained severe diarrhea (e.g., ≥ 10 liquid bowel movements per day; LR 5, 100% agreement in second survey) and severe immunosuppression (LR 5, 87% agreement in second survey).

Infectious disease experts concurred on the importance of signs, symptoms, and healthcare exposures for diagnosing CDI. The resulting risk estimates can be used by clinicians to optimize CDI testing and treatment.

The aim of this study was to evaluate theprevalence of night eating syndrome (NES) and its correlates in schizophrenicoutpatients.

The 14 items of self-reported night eatingquestionnaire (NEQ) was administered to 201 schizophrenic patients in psychiatricoutpatient clinic. We examined demographic and clinical characteristics, bodymass index (BMI), subjective measures of mood, sleep, binge eating, andweight-related quality of life using Beck's Depression Inventory (BDI),Pittsburgh Sleep Quality Index (PSQI), Binge Eating Scale (BES) and Koreanversion of Obesity-Related Quality of Life Scale (KOQoL), respectively.

The prevalence of night eaters in schizophrenicoutpatients was 10.4% (21 of 201). Comparisons between NES group and non-NES grouprevealed no significant differences in sociodemographic characteristics, clinical status and BMI. Compared to non-NES, patients with NES reportedsignificantly greater depressed mood and sleep disturbance, more binge eatingpattern, and decreased weight-related quality of life. While 'morning anorexia'and 'delayed morning meal' (2 of 5 NES core components in NEQ) were notdiffered between groups, 'nocturnal ingestions', 'evening hyperphagia', and'mood/sleep' were more impaired in NES group.

These findings are the first to describe theprevalence and its correlates of night eaters in schizophrenic outpatients. These results suggest that NES has negative mental health implications, although it was not associated with obesity. Further study to generalize theseresults is required.

This cross-sectional study was aimed to investigate the factors associated with bipolar disorder in pregnant female, including sociodemographic parameters, social support, social conflict, suicidal idea and sleep.

A total of 84 pregnant female were recruited. They filled out self-completing questionnaires on sociodemographic factors, obstetric history, depressive symptoms and bipolarity. Depressive symptoms were assessed using the Korean version of the Edinburgh Postnatal Depression Scale (EPDS). Bipolarity was assessed using the Korean version of the Mood Disorder Questionnaire (K-MDQ).

Nineteen participants (22.6%) had positive K-MDQ scores, suggesting the present of bipolarity. Positive EPDS group had twenty subjects (25%) who had depressive symptoms. The diathesis of bipolar disorder was associated with marital dissatisfaction, social conflict, depression and sleep. The multiple logistic regression analysis revealed that the only poor sleep was a risk of bipolarity.

Pregnant female with bipolarity were more depressed and sleep problems than those without bipolarity. The results showed that the most important factor of influencing bipolarity was sleep.

This study aimed to explore thedifference in emotional recognition of musical auditory stimulation and artfulvisual stimulation between helathy people and patients with schizophrenia.

20 songs and 20 paintings thatcontained sad or cheerful emotions were presented to 123 patients withschizophrenia and 224 healthy people as control group. The subjects were askedto tell about their emotions that they had felt from each musical auditorystimulation and artful visual stimulation. To measure such emotions, the Emotional Empathy Scale was used. The level of psychopathology in patientsgroup were evaluated with the Positive and Negative Syndrome Scale and the Formal Thought Disorder Rating Scale.

The correct answer rate to musical auditoryand artful visual stimulation of the patient group was significantly lower than that of thecontrol group. Thepatient group showed lower emotional empathic ability compared to the controlgroup. In the patient group, the correct answer rate to musical and artfulstimulation showed a negative correlation with score with Formal ThoughtDisorder Rating Scale.

Patients with schizophrenia have difficulties inprecise emotional recognition to auditory and visual stimulations, and this isassociated with lowered empathic ability and thinking disorder of patients withschizophrenia. If an psychosocial rehabilitation program or psychotherapy isimplemented to patients with schizophrenia, it is deemed to be necessary to make a mediation to improve the emotional recognition and expression ability of patients with schizophrenia.

This study was aimed to discover the correlation between those getting tattoos and their psychopathology relating to their delinquent behavior and emotional problems.

Date for this study was collected from 19-year-old men who were receiving a physical examination for conscription at the Korea Military Manpower Administration. 400 data sheets were collected among them. All of sjubjects were evaluated on the following measures: sociodemographic variants, Juvernile delinquency scale, State-trait anger expression inventory, Beck depression inventory, State-triat anxiety inventory, and Positive affect and negative affect schedule.

In comparison with those without tattooes, those with a tattoo scored higher in the scales that were related to delinquency, anger, depression, and negateive emotion. Furthermore, there were positive correlations between the number of tattoos and the scores for the Juvenile delinquent tendency and behavior scale as well as on the State-triat anxiety scale.

Those with tattoos had experienced anger, anxiety, and depression more strongly in comparison with those without tattoos. These reults recommended that tattooed males should be evaluated more on their regrading psychopathology compared to those without tattoos.

Thisstudy was to assess the prevalence and its correlates of restless legs syndrome(RLS) in outpatients with bipolar disorder.

A total of 100clinical stabilized bipolar outpatients were examined. The presence of RLS andits severity were assessed using the International Restless Legs Sydrome StudyGroup (IRLSSG) diagnostic criteria. Beck's Depression Inventory (BDI), Spielberg's StateAnxiety Inventory (STAI-X-1), Pittsburgh Sleep Quality Index (PSQI), Koreanversion Drug Attitude Inventory (KDAI-10), Subjective Well-Beings under NeurolepticTreatment Scale-Short Form(SWN-K) and Barnes Akathisia Rating Scale (BARS) wereused to evaluate the depressive symptomatology, level of anxiety, subjectivequality of sleep, subjective feeling of well-being, drug attitude, presence ofakathisia, respectively.

Of the 100 bipolar outpatients,7 (7%) were met to full criteria of IRLSSG and 36 (36%) have at least one ofthe 4 IRLSSG criterion. Because of relatively small sample size, non-parametricanalysis were done to compare the characteristics among 3 groups (full-RLS, 1≥positiveRLS-symptom and Non-RLS). There were no significant differences in sex, age, and other sociodemographic and clinical data among 3 groups. BDI, STAI-X-1 andPSQI are tended to be impaired in RLS and 1≥positive RLS-symptomgroups.

This is the first preliminarystudy for studying the prevalence and its correlates of RLS in bipolardisorder. The results shows that RLS was relatively smaller presentin bipolar disorder than schizophrenia. Sametendencies shown in schizophrenic patients were found that bipolar patientswith RLS had more depressive symptoms, state anxiety and poor subjective sleepquality.

The aim of this study was to monitor changes of prescription trends for bipolar disorder in inpatient settings in one university hospital.

A retrospective chart review was performed and data of 188 cases (2009–2012) and 118 cases (1998–2001) with a diagnosis of bipolar disorder were collected. Data on demographic variables, duration of hospitalization, kinds of psychotropic medications and the patterns of prescription over each four-year period were analyzed.

The proportion of patients with manic episode was decreased, whereas those of mixed and depressive episodes were increased. The use of lithium was decreased with the increased use of valproate. Increased use of lamotrigine in depressive episode was prominent. The use of combination treatment with mood stabilizers and antipsychotics was almost same level in both periods. The use of typical antipsychotics was significantly decreased and that of atypical antipsychotics was increased. Especially, the use of quetiapine showed great increase. In bipolar depression, the use of antidepressant was increased.

Data showed that quetiapine monotherapy had favorable effect on acute manic symptoms and well tolerated. Also this result suggests that quetiapine monotherapy may improve the self-perceived quality of sleep without any daytime impairment following sleep in acute manic patients.

Despite the advance in pharmacotherapy for posttraumatic stress disorder (PTSD), poor treatment adherence to pharmacotherapy for PTSD is a critical issue.

We intended to evaluate the predictors of premature discontinuation of psychiatric outpatient treatment after discharge for noncombat-related PTSD.

This study aimed to examine the sociodemographic and disease-related variables associated with the premature discontinuation of psychiatric outpatient treatment after discharge among patients with non-combat-related posttraumatic stress disorder.

We retrospectively reviewed the medical records of patients who were discharged with a diagnosis of posttraumatic stress disorder.

Fifty-five percent of subjects prematurely discontinued outpatient treatment within 6 months of discharge. Comparing sociodemographic variables between the 6-month non-follow-up group and 6-month follow-up group, there were no variables that differed between the two groups. However, comparing disease-related variables, the 6-month follow-up group showed a longer hospitalization duration and higher Global Assessment of Function score at discharge. The logistic regression analysis showed that a shorter duration of hospitalization predicted premature discontinuation of outpatient treatment within 6 months of discharge.

The duration of psychiatric hospitalization for posttraumatic stress disorder appeared to influence the premature discontinuation of outpatient treatment after discharge.

This study examined the prescribing patterns for medications to treat bipolar disorder in outpatient-based psychiatric practice focusing on atypical antipsychotics.

Retrospective chart review of patients admitted to a university hospital with a primary diagnosis of bipolar disorder in a period from January 2008 to December 2012 was conducted. We reviewed Diagnostic and Statistical Manual of Mental Disorders, fourth edition diagnosis and detailed clinical information at index episode. Psychotropic medications were grouped into six categories; atypical antipsychotics, typical antipsychotics, lithium, anticonvulsants, antidepressants, and minor tranquilizers. Severity, rapid cycling type, psychiatric comorbidity and disease duration were computed focusing on atypical antipsychotics.

In 344 patients who were prescribed major psychotropic medications, atypical antipsychotics were prescribed in 70.9% of subjects, anticonvulsants in 73.3%, lithium in 36.9%, antidepressants in 41.9%, and typical antipsychotics in 0.9% of subjects. About 12.5% of subjects were treated with the monotherapy. Atypical antipsychotics prescription was favored in subjects with manic and mixed episodes or severe episode. Prescribing trend is independent of rapid cycling type. Prescription of antidepressants were more frequent in subjects who were recently diagnosed as bipolar disorder or prescribed new medications or existed psychiatric comorbidity.

The development of bipolar disorder's psychopharmacology has been reflected in the prescription pattern of psychotropic medications in Korea. This study suggests that atypical antipsychotics have played major role in treatment of bipolar disorder.

The purpose of this study was to evaluate the occurrence of the suicidal ideation and associated factors with self-reported suicidal ideation within the last 12 months among Korean adolescents.

A total of 1533 adolescents were recruited from middle schools (age range: 13-14 years) in Korea. According to existence of suicidal ideation, they were divided 2 group – suicidal ideation group and non-suicidal ideation group, and the differences between groups in terms of various characteristics, including depression (Kovacs’ Children’s Depression Inventory), school and family factors, and health related conditions.

A total of 501 (32.7%) middle school students reported suicidal ideation, and the rate of suicidal attempt was 6.9% (n=106). The associated factors of suicidal ideation were female (OR= 2.42, p<0.001), below average academic achievement (OR=1.43, p=0.007), perceived low parental support (OR=2.09, p=0.001), depression (OR=3.25, p<0.001), current alcohol use (OR=2.37, p=0.003), self reported poor health (OR=1.54, p =0.043), and school bullying (OR=1.91, p =0.005).

These results may have important implications for the strategies and specified intervention in preventing suicidal ideation in Korean adolescents.

We evaluated the difference in sleep skills between patients with and without need of hypnotics after sleep CBT.

Total 131 insomnia patients' sleep disturbances were assessed by visual analogue scales. Patients received 9 sessions of sleep CBT and were prescribed hypnotics for prn during 3 months. Sleep CBT was focused on the sleep hygiene and sleep stimulus-control guidelines. Sleep hygiene guidelines were Limit the time spent in bed (SH1), Get regular exercise (SH2), Avoid light at night (SH3), Avoid heavy meals or drinking (SH4), Quiet, dark, and comfortable bedroom (SH5), Avoid caffeine, alcohol, and nicotine (SH6), Relaxing bedtime routine (SH7),Llight bedtime snack (SH8), Remove the bedroom clock (SH9). Sleep stimulus-control guidelines were Go to bed only when sleepy (SSC1), Use the bed for sleeping or sex (SSC2), Get out of bed when unable to sleep (SSC3), Get up at the same time (SSC4), Avoid napping (SSC5). Each sleep skill state was evaluated by Likert scale, and they were compared between before and after CBT. Patients were divided into two groups: still need of hypnotics and no need of hypnotics after 3 months.

Forty-six (35.1%) patients replied they needed not hypnotics any more, but 85 (64.9%) patients replied they still needed hypnotics after CBT. Sleep VAS (25.26±8.52 vs. 32.64±8.95, p<0.001), SH2 (3.67±0.92 vs. 2.76±1.06, p=0.030), SH7 (4.08±0.55 vs. 2.76±0.76, p<0.001) were different in two groups.

Among several CBT skills, regular moderate exercise in daytime and a relaxing bedtime routine seem to be key components.
