Observational Study
The association between maximal muscle strength, disease severity and psychopharmacotherapy among young to middle-aged inpatients with affective disorders - a prospective pilot study.
BACKGROUND
Motor alterations and lowered physical activity are common in affective disorders. Previous research has indicated a link between depressive symptoms and declining muscle strength primarily focusing on the elderly but not younger individuals. Thus, we aimed to evaluate the relationship between mood and muscle strength in a sample of N = 73 young to middle-aged hospitalized patients (18-49 years, mean age 30.7 years) diagnosed with major depressive, bipolar and schizoaffective disorder, with a focus on moderating effects of psychopharmacotherapy. The study was carried out as a prospective observational study at a German psychiatric university hospital between September 2021 and March 2022.
METHODS
Employing a standardized strength circuit consisting of computerized strength training devices, we measured the maximal muscle strength (F) using three repetitions maximum across four muscle regions (abdomen, arm, back, leg) at three time points (t-t) over four weeks accompanied by psychometric testing (MADRS, BPRS, YRMS) and blood lipid profiling in a clinical setting. For analysis of psychopharmacotherapy, medication was split into activating (AM) and inhibiting (IM) medication and dosages were normalized by the respective WHO defined daily dose.
RESULTS
While we observed a significant decrease of the MADRS score and increase of the relative total F (rTF) in the first two weeks (t-t) but not later (both p < .001), we did not reveal a significant bivariate correlation between disease severity (MADRS) and muscle strength (rTF) at any of the timepoints. Individuals with longer disease history displayed reduced rTF (p = .048). IM was significantly associated with decreased rTF (p = .032). Regression models provide a more substantial effect of gender, age, and IM on muscle strength than the depressive episode itself (p < .001).
CONCLUSIONS
The results of the study indicate that disease severity and muscle strength are not associated in young to middle-aged inpatients with affective disorders using a strength circuit as observational measurement. Future research will be needed to differentiate the effect of medication, gender, and age on muscle strength and to develop interventions for prevention of muscle weakness, especially in younger patients with chronic affective illnesses.

Observational Study
BACKGROUND
In clinical practice, the implementation of tailored treatment is crucial for assessing the patient's emotional processing profile. Here, we investigate all three levels of analysis characterizing emotion processing, i.e., recognition, representation, and regulation, in patients with peripheral neuropathic pain (PNP).
METHODS
Sixty-two patients and forty-eight healthy controls underwent quantitative sensory testing, i.e., psychophysical tests to assess somatosensory functions such as perception of cold (CDT), heat-induced pain (HPT), and vibration (VDT), as well as three standardized tasks to assess emotional processing: (1) the Ekman 60-Faces Test (EK-60F) to assess recognition of basic facial emotions, (2) the Reading the Mind in the Eyes Test (RME) to assess the ability to represent the feelings of another person by observing their eyes, and (3) the 20-item Toronto Alexithymia Scale (TAS-20) to assess emotional dysregulation, i.e., alexithymia.
RESULTS
General Linear Model analysis revealed a significant relationship between left index finger VDT z-scores in PNP patients with alexithymia. The RME correlated with VDT z-scores of the left little finger and overall score for the EK-60F.
CONCLUSIONS
In patients with PNP, emotion processing is impaired, which emphasizes the importance of assessing these abilities appropriately in these patients. In this way, clinicians can tailor treatment to the needs of individual patients.

BACKGROUND
Individuals at clinical high risk (CHR) for psychosis experience subtle emotional disturbances that are traditionally difficult to assess, but natural language processing (NLP) methods may provide novel insight into these symptoms. We predicted that CHR individuals would express more negative emotionality and less emotional language when compared to controls. We also examined associations with symptomatology.
METHODS
Participants included 49 CHR individuals and 42 healthy controls who completed a semi-structured narrative interview. Interview transcripts were analyzed using Linguistic Inquiry and Word Count (LIWC) to assess the emotional tone of the language (tone -the ratio of negative to positive language) and count positive/negative words used. Participants also completed clinical symptom assessments to determine CHR status and characterize symptoms (i.e., positive and negative symptom domains).
RESULTS
The CHR group had more negative emotional tone compared to healthy controls (=2.676, =.009), which related to more severe positive symptoms (=.323, =.013). The percentages of positive and negative words did not differ between groups ('s>.05).
CONCLUSIONS
Language analyses provided accessible, ecologically valid insight into affective dysfunction and psychosis risk symptoms. Natural language processing analyses unmasked differences in language for CHR that captured language tendencies that were more nuanced than the words that are chosen.

The validity and reliability of the Chinese version of the biological rhythms interview of assessment in neuropsychiatry in the community: a large Chinese college student population.
OBJECTIVE
To test the psychometric properties of the Chinese version of the biological rhythms interview of assessment in neuropsychiatry (C-BRIAN) in a group of young adults with and without depressive symptoms.
METHODS
Three hundred and seventy-eight university students were recruited as participants. Based on the scores from Center for Epidemiological Survey Depression Scale (CES-D), students were divided into the depressed group and healthy group. Explorative factor analysis was applied to assess the construct validity of the C-BRIAN. The Pittsburgh Sleep Quality Index (PSQI) and CES-D were compared with the C-BRIAN to test the convergent validity. The internal consistency of the C-BRIAN was also examined.
RESULTS
Three factors were extracted (activities, eating patterns, and sleep factors) explaining 63.9% of the total variance. The internal consistencies were very good with a coefficient of 0.94 (overall) and 0.89-0.91 for three factors. The domains of activities, eating patterns, and sleep were moderately correlated with PSQI (=0.579) and CES-D (=0.559) (ps<0.01).
CONCLUSION
Our findings suggest that C-BRIAN has good validity and reliability which can be used to assess the biological rhythm in the young adult population with depressive symptoms. C-BRIAN would be a reliable tool to detect depressive symptoms for timely prevention and intervention in the community.

BACKGROUND
Understanding the evolution of circadian rhythm dysfunction and psychopathology in the high-risk population has important implications for the prevention of bipolar disorder. Nevertheless, some of the previous studies on the emergence of psychopathologies and circadian dysfunction among high-risk populations were inconsistent and limited.
AIMS
To examine the prevalence rates of sleep and circadian dysfunctions, mental disorders and their symptoms in the offspring of parents with (O-BD) and without bipolar disorder (O-control).
METHODS
The study included 191 O-BD and 202 O-control subjects aged 6-21 years from the Greater Bay Area, China. The diagnoses and symptoms of sleep/circadian rhythm and mental disorders were assessed by the Diagnostic Interview for Sleep Patterns and Disorders, and the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version, respectively. Generalised estimating equations and shared frailty proportional hazards models of survival analysis were applied to compare the outcomes in the offspring.
RESULTS
Adjusting for age, sex and region of recruitment, there was a significantly higher risk of delayed sleep phase symptoms (9.55% vs 2.58%, adjusted OR: 4.04) in O-BD than in O-control. O-BD had a nearly fivefold higher risk of mood disorders (11.70% vs 3.47%, adjusted OR: 4.68) and social anxiety (6.28% vs 1.49%, adjusted OR: 4.70), a fourfold higher risk of depressive disorders (11.17% vs 3.47%, adjusted OR: 3.99) and a threefold higher risk of mood symptoms (20.74% vs 10.40%, adjusted OR: 2.59) than O-control. Subgroup analysis revealed that O-BD children (aged under 12 years) had a nearly 2-fold higher risk of any mental and behavioural symptoms than O-control, while there was a nearly 4-fold higher risk of delayed sleep phase symptoms, a 7.5-fold higher risk of social anxiety and a 3-fold higher risk of mood symptoms in O-BD adolescents (aged 12 years and over).
CONCLUSIONS
There was an increase in delayed sleep phase symptoms in O-BD adolescents compared with their control counterparts, confirming the central role of circadian rhythm dysfunction in bipolar disorder. The findings of the specific age-related and stage-related developmental patterns of psychopathologies and circadian dysfunction in children and adolescent offspring of parents with bipolar disorder paved the way to develop specific and early clinical intervention and prevention strategies.

INTRODUCTION
Delivering cognitive behavioral therapy for insomnia over the internet bears the advantage of accessibility and uptake to many patients suffering from chronic insomnia. In the current study, we aimed to investigate the effectiveness of internet-based cognitive behavioral therapy for insomnia (iCBT-I) in routine care.
MATERIALS AND METHODS
We conducted a two-arm non-blinded randomized controlled trial with care as usual (CAU) as a control condition. Participants were recruited in a specialized outpatient sleep medicine department. Both arms had access to other healthcare resources, and the intervention group had access to the iCBT-I program for 2 months. The primary outcome was insomnia severity, measured by the Insomnia Severity Index (ISI). Secondary outcomes were fatigue severity, daytime sleepiness, affective symptoms, dysfunctional beliefs and attitudes about sleep, sleep locus of control, sleep hygiene, sleep efficiency (SE), sleep onset latency, wake time after sleep onset (WASO), and total sleep time (TST). Linear mixed models for repeated measures were used to analyze the longitudinal data at baseline, post-treatment, and after 3 months of follow-up. The trial was registered at www.clinicaltrials.gov (NCT04300218 21.04.2020).
RESULTS
The results showed a significant time*group interaction effect ( = 0.001) at post-treatment with between-group effect size ( = 0.51), indicating that the ISI decreased by a score of 3.8-fold in the iCBT-I group than in the CAU group. There was no significant difference in ISI between groups at follow-up. Regarding secondary outcomes, dysfunctional beliefs about sleep, SE, and WASO decreased significantly during treatment in the intervention group with between-group effect sizes = 0.35, = 0.51, and = 0.47, respectively. At the follow-up, between-group effects on DBAS and SE remained significant: = 0.36 and = 0.63, respectively. For TST, we observed a significant time*group effect of = 0.38 only after follow-up.
CONCLUSION
Our findings suggest that iCBT-I has a significant effect on insomnia severity at post-treatment compared to CAU. iCBT-I further improved dysfunctional beliefs about sleep and improved subjective sleep characteristics, such as SE, WASO, and TST during 3 months after treatment.

INTRODUCTION
Glial cell derived neurotrophic factor (GDNF) has an important role in the pathogenetic mechanisms and clinical manifestations of rheumatoid arthritis (RA). Alexithymia is associated with a severe clinical course and worse prognosis, while the relationship between alexithymia and GDNF in RA patients has not been investigated before. The aims of the study were to investigate the GDNF level in blood plasma in RA patients depending on the presence of alexithymia and to evaluate the relationship of GDNF level with clinical manifestation and quality of life.
MATERIAL AND METHODS
Fifteen men and 73 women with RA were examined using the Disease Activity Score with 28-joint count (DAS28) with erythrocyte sedimentation rate (ESR) index, the Simple Disease Activity Index (SDAI), the Rheumatoid Arthritis Clinical Disease Activity Index (CDAI), the Visual Analogue Scale (according to the assessment of the patient - VAS-P and the assessment of the doctor - VAS-D), the Health Assessment Questionnaire (HAQ), the Toronto Alexithymia Scale (TAS-20), the Disability Rating Index (DRI) and SF-36 indexes. Glial cell derived neurotrophic factor level in the blood plasma was determined by enzyme-linked immunosorbent assay (ELISA).
RESULTS
Forty percent of RA patients had alexithymia. Glial cell derived neurotrophic factor level in the examined patients was 3.73 ±2.59 pg/ml, in patients with alexithymia 4.08 ±2.87 pg/ml, without alexithymia 3.48 ±2.37 pg/ml ( = 0.295). Patients with alexithymia had a higher erythrocyte sedimentation rate (ESR) and index scores than patients without alexithymia - ESR: 34.29 ±14.22 vs. 22.73 ±12.03 mm/h ( = 0.017), DAS28: 6.53 ±0.66 vs. 6.09 ±0.55 ( = 0.017), VAS-D: 7.19 ±0.81 vs. 6.53 ±0.83 ( = 0.020), HAQ: 1.78 ±0.58 vs. 1.51 ±0.54 ( = 0.040). Also they had worse SF-36 indicators - physical functioning: 39.52 ±13.78 vs. 51.00 ±14.90 ( = 0.019), role functioning due to physical condition: 30.95 ±20.77 vs. 46.67 ±24.76 ( = 0.041), physical component of health: 31.47 ±11.44 vs. 41.61 ±15.88 ( = 0.028). In patients with alexithymia, a correlation was found between the GDNF level and severity of pain according to VAS-P: = 0.338, = 0.044, and VAS-D: = 0.446, = 0.006.
CONCLUSIONS
Alexithymia was found in 40% of RA patients. Rheumatoid arthritis patients with alexithymia had a nonsignificantly higher GDNF level compared to patients without alexithymia. In RA patients with alexithymia, an association of GDNF level in the blood plasma with RA activity, loss of functional capacity and reduced quality of life was established. Alexithymia in RA patients is an important factor in the clinical manifestation of RA and modification of the pathophysiological role of GDNF.

Emerging research in non-human animals implicates cerebellar projections to the ventral tegmental area (VTA) in appetitive behaviors, but these circuits have not been characterized in humans. Here, we mapped cerebello-VTA white-matter connectivity in humans using probabilistic tractography on diffusion imaging data from the Human Connectome Project. We uncovered the topographical organization of these connections by separately tracking from parcels of cerebellar lobule VI, crus I/II, vermis, paravermis, and cerebrocerebellum. Results revealed that connections from the cerebellum to the VTA predominantly originate in the right hemisphere, interposed nucleus, and paravermal cortex, and terminate mostly ipsilaterally. Paravermal crus I sends the most connections to the VTA compared to other lobules. We discovered a medial-to-lateral gradient of connectivity, such that the medial cerebellum has the highest connectivity with the VTA. Individual differences in microstructure were associated with measures of negative affect and social functioning. By splitting the tracts into quarters, we found that the socio-affective effects were driven by the third quarter of the tract, corresponding to the point at which the fibers leave the deep nuclei. Taken together, we produced detailed maps of cerebello-VTA structural connectivity for the first time in humans and established their relevance for trait differences in socio-affective regulation.

Being a man has been recognized as a salient risk factor for suicide. Adopting uncompromised masculine perceptions (i.e., conforming to the masculine gender role norms) may restrict emotional expressiveness in men, which, in turn, may contribute to depression and somatization symptoms. We examined the moderating role of psychological flexibility and alexithymia in the relationship of masculinity with depression and somatization symptoms. A sample of 119 men completed measures of masculinity, alexithymia (difficulty identifying and delivering subjective feelings), psychological flexibility, depression, and somatization symptoms in a cross-sectional design study. Psychological flexibility levels moderated the relationship between masculinity and depression symptoms: Masculinity contributed as positively associated with depression symptoms when psychological flexibility was low, but no such association was found at moderate or high levels of psychological flexibility. As a cognitive factor promoting adaptive emotional regulation, psychological flexibility might reduce depression symptoms among inflexible masculine men. Clinical implications relate to diagnosing at-risk subgroups and their treatment.
