Evaluation of Galectin-1 and Galectin-3 levels in patients with bipolar disorder: Is Galectin-3 associated with treatment response?

INTRODUCTION: Galectins (Gal) were linked with inflammatory responses in the central nervous system, may play an important role in the pathogenesis of BD.In this study,we aimed to investigate whether serum Gal-1 and Gal-3 levels are related to BD. METHODS: 36 patients diagnosed with BD were included.C-Reactive Protein(CRP),Gal-1,Gal-3 blood levels were evaluated on the first day of hospitalization and the third week of treatment and compared with 41 healthy controls.The severity of the illness was evaluated with the Young Mania Rating Scale (YMRS). RESULTS: CRP levels of BD patients at hospitalization were significantly higher than the third week of treatment and healthy controls.Gal-1 levels on the first day of hospitalization and the third week of treatment were found higher than the healthy controls.There was no significant difference in Gal-3 levels of the patients on the day of hospitalization compared to healthy controls;at the end of the 3rd week of treatment,Gal-3 was statistically significantly higher than the first day of hospitalization. CONCLUSION: Our study is valuable in that it is the first study to show the change in Gal levels after treatment and to evaluate the role of Gal in BD.Gal-1 may play roles in the pathophysiology of BD.Gal-3 may be a biomarker candidate for the evaluation of the treatment response.

Neutrophil gelatinase-associated lipocalin (NGAL) and inflammatory markers in schizophrenia: A comparative analysis of drug-naive schizophrenia patients, remitted patients, and healthy controls.

This study aims to examine the plasma concentrations of NGAL and other inflammatory parameters, including TNF-α, IL-1ß, and IFN-γ, in schizophrenia patients and healthy volunteers. It also investigates potential associations between these biomarkers and symptom severity in schizophrenia and the utility of NGAL as a potential diagnostic and monitoring biomarker for schizophrenia. The study included 49 drug-naive schizophrenia patients (DNS), 59 patients with schizophrenia in remission (REM) on antipsychotic treatment, and 58 healthy volunteers (HC). The Positive and Negative Symptoms Evaluation Scale (PANSS) was utilized to assess the severity of symptoms in schizophrenia patients. Plasma levels of TNF-α, IL-1ß, IFN-γ, and NGAL were measured for all participants. NGAL levels were significantly lower in the DNS group than in HC. Significantly lower TNF-α levels were observed in both the DNS and REM groups compared to the HC group. Notably, a statistically significant positive correlation was detected between TNF-α and NGAL levels. The findings of this study are noteworthy, as they demonstrate that drug-naive individuals with schizophrenia exhibit significantly diminished levels of NGAL and TNF-α compared to healthy controls. These identified biomarkers hold promise for providing valuable insights into the complex and evolving pathophysiology of schizophrenia.

Surviving the Immediate Aftermath of a Disaster: A Preliminary Investigation of Adolescents' Acute Stress Reactions and Mental Health Needs after the 2023 Turkey Earthquakes.

On 6 February, southeastern Turkey and parts of Syria were struck by two powerful earthquakes, one measuring a magnitude of 7.8 and the other, nine hours later, at a magnitude of 7.5. These earthquakes have been recorded as some of the deadliest natural disasters worldwide since the 2010 Haiti earthquake, impacting around 14 million people in Turkey. For trauma survivors, the stressors associated with an event can lead to the development of acute stress disorder (ASD) or other psychiatric disorders. Trauma experiences during adolescence can impact development and affect adolescents differently than adults. Although ASD in adults has been addressed in several studies, there is much less information available about how younger populations respond to acute stress. The aim of our study was to assess the occurrence of ASD among individuals seeking help at the Sanliurfa Mehmet Akif Inan Research and Training Hospital Child and Adolescent Outpatient Clinic following the 2023 Turkey Earthquakes and the factors associated with acute stress reactions. A child and adolescent psychiatry specialist conducted psychiatric interviews with the adolescents, and the individuals were also asked to complete 'The National Stressful Events Survey Acute Stress Disorder Short Scale' (NSESSS) to evaluate acute stress symptoms. ASD diagnoses were established according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria. Results showed that 81.6% of the participants (n = 49) were diagnosed with ASD, and drug treatment was initiated in 61.7% of the cases (n = 37). It was determined that ASD rates did not differ according to gender, and patients without physical injury had higher acute stress symptom scores (p > 0.05). According to the logistic regression models, paternal educational levels and adolescents' own requests for psychiatric assistance were predictors of acute stress disorder (OR 10.1, ß = 2.31, p = 0.006 and OR 16.9, 95 ß = 2.83, p = 0.001, respectively). Our findings revealed striking results in demonstrating the need for careful evaluation of adolescents without physical injury in terms of acute stress disorder and the need to pay close attention to the psychiatric complaints of adolescents willing to seek mental health assistance. Moreover, our study suggests that the proportion of adolescents experiencing acute stress symptoms after earthquakes might be higher than previously reported. Estimation of the incidence rate and symptoms of psychiatric distress in the short-term period following a disaster is important for establishing disaster epidemiology and implementing efficient relief efforts in the early stages. The outcomes of this study have the potential to yield novel insights into the realms of disaster mental health and emergency response policies, as well as their pragmatic implementations.

Attachment Security and Cortical Activity Measured by Functional Near-Infrared Spectroscopy During a Working Memory Task in Healthy Young Adults.

Introduction: Attachment style has been associated with socio-emotional outcomes, however little evidence suggests a possible association with executive functioning. Few studies have demonstrated that attachment style mediates working memory and learning relationships. We hypothesized that attachment style affects performance and cortical activity patterns of working memory. Methods: We compared working memory performance and cortical activity in securely and insecurely attached first-year college students (N=49) using three n-back task conditions. Cortical activity was recorded by functional near-infrared spectroscopy during these three conditions of the n-back task. Attachment style was assessed using the Relationship Scale Questionnaire, categorized into four groups. Results: Both study groups showed similar working memory performance. The cortical representation of working memory was different between the two groups. The securely attached group demonstrated higher activity in the right superior frontal and superior-medial frontal areas across all n-back conditions as well as in the right superior frontal cortex during the two-back and three-back conditions. The insecurely attached group displayed higher activity in the bilateral supplementary motor area and the left premotor area only during the three-back condition. Conclusion: These findings emphasize the potential influence of attachment style on the cortical representation of working memory. Different activity maps between the two groups may reflect varying cognitive strategies employed to achieve a comparable working memory performance. Moreover, these results suggest that each style may have a distinct strategy to achieve attachment-relevant and irrelevant neurocognitive tasks.

Neutrophil gelatinase-associated lipocalin (NGAL) and tumor necrosis factor-α (TNF-α) levels in patients with schizophrenia.

RATIONALE: Although the immune system is thought to contribute to the etiology of schizophrenia, the mechanism has not been elucidated. Clarifying the relationship between them is important in terms of diagnosis, treatment, and prevention approaches. OBJECTIVE: In this study, it is aimed to determine whether there is any difference in serum levels of neutrophil gelatinase-associated lipocalin (NGAL) and tumor necrosis factor-alpha (TNF-α) in the group of patients with schizophrenia and healthy volunteers, whether these values are changed by medical treatment, whether there is any relation between these values and the severity of the symptoms of patients with schizophrenia, and whether NGAL can be used as a biomarker in the diagnosis and the follow-up of the schizophrenia. METHODS: A total of 64 patients who were hospitalized in the Psychiatry Clinic of Ankara City Hospital and diagnosed with schizophrenia and 55 healthy volunteers were included in the study. A sociodemographic information form was given to all participants and TNF-α and NGAL values were measured. Positive and Negative Symptoms Rating Scale (PANSS) were applied to the schizophrenia group on admission and follow-up. TNF-α and NGAL levels were re-measured in the 4th week after the start of antipsychotic treatment. RESULTS: As a result of the present study, it was found that NGAL levels decreased significantly after antipsychotic treatment of schizophrenia patients hospitalized with exacerbation. There was no significant correlation between NGAL and TNF-α levels among schizophrenia and the control group. CONCLUSION: In psychiatric diseases, especially schizophrenia, there may be differences in immune and inflammatory markers compared to the healthy population. After treatment, the NGAL levels of the patients at follow-up were reduced compared to the levels at admission. It can be thought that NGAL may be related to psychopathology in schizophrenia and antipsychotic treatment. This is the first follow-up study for NGAL levels in schizophrenia.

Evaluation of psychological resilience and anxiety levels of patients with hyperemesis gravidarum diagnosis and comparison with healthy pregnant women

Objective: To compare the psychological resilience and anxiety levels of patients diagnosed with hyperemesis gravidarum (HG) and healthy pregnant women. Materials and Methods: A sociodemographic data form and the Resilience scale for Adults (RSA) and the State-Trait Anxiety Inventory (STAI) were administered. The sociodemographic data form was completed by the physician, and the RSA and STAI were completed by the participant. The sample of the study consisted of 60 pregnant women with HG and hospitalized and 97 healthy voluntary pregnant women with similar characteristics to the research group without any pregnancy complications. Data were evaluated using descriptive statistical analyses, the independent samples t-test, the Mann-Whitney U test and Pearson's correlation analysis. Results: The age range was 18-42 years for HG group and 20-43 years for control group. The average age of the HG group was 28.17±5.96 years and that of the control group was 29.45±5.83 years. There was no statistically significant difference between the groups in terms of pregnancy week. Regarding the prevalence of state and trait anxiety between the groups, it was found that 66.7% of the HG group had a high level of trait anxiety and 51.7% had a high level of state anxiety. It was found that 61.9% of the control group had a high level of trait anxiety and 38.1% had a high level of state anxiety. There was no difference between the healthy pregnant group and the HG group in terms of anxiety (p=0.125). It was found that there was a significant difference between the groups in terms of only sub-dimensions of RSA, which were perception of self (U=2385.00, p=0.044) and perception of future (U=2350.50, p=0.030). The perception of self and perception of future scores of the healthy control group were higher. Conclusion: There was no difference between the healthy pregnant group and the HG group in terms of anxiety. It was observed that the HG group had a lower perception of self and future. Apart from the usual increase in anxiety levels during pregnancy, HG accompanied by stubborn nausea and vomiting does not create an extra psychological burden, either as a cause or a result.

Cortical activity measured by functional near infrared spectroscopy during a theory of mind task in subjects with schizophrenia, bipolar disorder and healthy controls.

Theory of Mind (ToM) deficits interfere in social cognitive functioning in schizophrenia (SCZ) and are increasingly recognized to do so in bipolar disorder (BD), however their clinical and neurobiological correlates remain unclear. This study represents the first direct comparison of subjects with SCZ (N = 26), BD (N = 26) and healthy controls (N = 33) in cortical activity during the Reading the Mind in the Eyes Task (RMET) using functional Near Infrared Spectroscopy (fNIRS) with the control condition (CC) involving gender identification via the same stimuli. The three groups were compared with a comprehensive ToM battery and assessed in terms of the relationship of ToM performance with clinical symptoms, insight and functioning. The controls scored higher than the SCZ and BD groups in ToM assessments, with SCZ group showing the worse performance in terms of meta-representation and empathy. The SCZ group ToM scores inversely correlated with negative symptom severity and positively correlated with insight; BD group ToM scores negatively correlated with subclinical mania symptoms and projected functioning. Cortical activity was higher during the ToM condition compared to the CC in the pre-motor and supplementary-motor cortices, middle and superior temporal gyri, and the primary somatosensory cortex. Group x Condition interaction was detected whereby activity was higher during the ToM condition among controls with no detected difference between SCZ and BD groups. The results suggest that ToM is represented similarly in cortical activity in SCZ and BD compared to healthy controls pointing to possible neurobiological convergence of SCZ and BD in underlying impairments of social cognition.

The relationship of cortical activity induced by pain stimulation with clinical and cognitive features of somatic symptom disorder: A controlled functional near infrared spectroscopy study.

OBJECTIVE: The neurobiological correlates of Somatic Symptom Disorder (SSD) introduced in the DSM-5 has been the focus of a limited investigation. We aimed to examine the cortical response to painful stimuli and its relationship to symptom severity as well as cognitive and psychological characteristics in proposed models of somatoform disorders. METHODS: We measured hemodynamic responses by 52-channel functional near-infrared spectroscopy. We compared the cortical response to painful stimuli in index patients with SSD (N = 21) versus age, and gender matched healthy control subjects (N = 21). We used brush stimulation as the control condition. We analyzed the relationship of cortical activity with SSD symptom severity as well as somatosensory amplification (SSA), alexithymia, dysfunctional illness behaviour, worry, and neuroticism. RESULTS: Patients with SSD had higher somatic symptom severity, SSA, alexithymia, neuroticism, illness-related worry, and behaviour. Somatic symptom severity was predicted by a model including SSA and subjective feeling of pain in the index patients. Activity in the left-angular and right-middle temporal gyri was higher in the SSD subjects than the controls during pain stimulation. Positive correlations were detected between mean pain threshold levels and left middle occipital gyrus activity, as well as between SSA-scores and right-angular gyrus activity during pain condition in the index patients with SSD. CONCLUSION: We present the first evidence that representation of pain in terms of cortical activity is different in subjects with SSD than healthy controls. SSA has functional neuroanatomic correlates and predicts symptom severity in SSD and therefore is involved as a valid intermediate phenotype in SSD pathophysiology.

Galectin-1 and Galectin-3 Levels in Patients with Schizophrenia and their Unaffected Siblings.

Many hypothesis suggest that inflammation plays an important role in schizophrenia. Galectins can regulate inflammatory response in central nervous system. The relation between galectins and neuropsyhchiatric diseases and schizophrenia is unclear. The present study compared levels of Gal-1 and Gal-3 of patients with schizophrenia to that of first-degree relatives without the disease and healthy controls in order to evaluate any possible association. Sixty-two patients with schizophrenia, fifty-five unaffected siblings and fifty-eight age- and sex-matched healthy controls enrolled. Serum Gal-1, Gal-3 and CRP levels were measured. PANNS and CGI-S were used to evaluate the severity of disease. There was a statistically significant difference in serum Gal-1 levels among the patient, sibling, and control groups. There were no statistically significant correlations between serum CRP ​​and serum Gal-1 or Gal-3 levels. Gal-1 values were significantly higher in the unaffected siblings compared to both the patient group and the healthy control group. Gal-3 levels were elevated in the sibling group relative to the patient group. In the literature, the relationship between galectins and schizophrenia is very limited and appears to be a new field of study. Future studies are needed to evaluate the protective roles of galectins.
