Face and emotion recognition in individuals diagnosed with schizophrenia, ultra-high risk for psychosis, unaffected siblings, and healthy controls in a sample from Turkey.

Face and emotion recognition are crucial components of social cognition. We aimed to compare them in patients diagnosed with schizophrenia (SCZ), ultra-high risk for psychosis (UHR), unaffected siblings of schizophrenia patients (SIB), and healthy controls (HC). METHODS: One hundred sixty-six participants (45 SCZ, 14 UHR, 45 SIB, and 62 HC) were interviewed with the Structured Clinical Interview for DSM-5 (SCID-5). Positive and Negative syndrome scale (PANSS), PennCNB Facial Memory (CPF), and Emotion Recognition Task (ER40) were applied. RESULTS: In CPF, SCZ performed significantly lower than SIB and HC. SIB was also significantly lower than HC for total correct responses. The sample size of the UHR group was small, and the statistical comparisons did not reach a significance, however, a trend towards decreased performance between the SCZ and SIB was found. In ER40, SCZ performed significantly lower than HC and SIB in all domains, except for the insignificant findings for angry ER between SIB and SCZ. SIB also performed significantly lower than HC for angry, negative, and total ER. UHR was similar to SCZ for happy and sad ER and performed significantly lower than HC for happy ER. The effect of SCZ diagnosis on the efficiency of CPF and ER40 was significant when corrected for age and education. For SCZ, PANSS also significantly affected the CPF and ER40. CONCLUSION: Our findings suggest varying levels of face and emotion recognition deficits in individuals with SCZ, UHR, and SIB. Face and emotion recognition deficits are promising schizophrenia endophenotypes related to social cognition.

Caregiver support and burden drive intention to engage in a peer-to-peer exchange of services among caregivers of dementia patients.

Introduction: The number of people diagnosed with dementia is increasing, creating significant economic burden globally. With the progression of the disease, patients need a caregiver whose wellbeing is important for continuous care. Providing respite as a service, through sharing the responsibility of caregiving or support for the caregiver, is a costly initiative. A peer-to-peer online support platform for dementia caregivers, motivated by the sharing economy, putting exchange of knowhow, resources, and services at its center, has the potential to balance cost concerns with a search for respite. The aim of this research is to assess caregivers' intention to engage in peer-to-peer exchange. Methods: A survey including sociodemographic, technology use, and caregiving variables, structured questionnaires (Zarit caregiver burden, WHO brief quality of life scale, ADCS-ADL and chronic stress scale) were administered, January 2018-May 2019, in the dementia outpatient clinic of a university hospital, to a convenience sample of n = 203 individuals identifying themselves as primary caregivers. A path analysis exploring the drivers of an intention to engage in peer-to-peer service exchange was conducted. Results: In the path model, caregivers experiencing higher caregiver burden showed higher intention to engage (0.079, p < 0.001). Disease stage had no effect while patient activities of daily living, chronic social role related stressors of the caregiver and general quality of life were significant for the effect on the caregiver burden. Existing household support decreased the caregiver burden, affecting the intention to engage. Caregivers who can share more know-how demonstrate a higher intention to engage (0.579, p = 0.021). Caregiver technology affinity (0.458, p = 0.004) and ability and openness to seek professional help for psychological diagnoses (1.595, p = 0.012) also increased intention to engage. Conclusion: The model shows caregiver burden to be a major driver, along with caregiver characteristics that reflect their technology affinity and openness to the idea of general reciprocity. Existing support for obtaining knowhow and exchanging empathy have a direct effect on the intention to engage. Given the scarcity of caregiver support in the formal care channels, the identified potential of enlarging informal support via a peer-to-peer exchange mechanism holds promise.

Test-retest reliability of the Turkish translation of the Penn Computerized Neurocognitive Battery.

Psychiatric disorders are associated with cognitive dysfunction (CD), and reliable screening and follow-up of CD is essential both for research and clinical practice globally; yet, most assessments are in Western languages. We aimed to evaluate the test-retest reliability of the Turkish version of the Penn Computerized Neurocognitive Battery (PennCNB) to guide confident interpretation of results. Fifty-eight healthy individuals completed the PennCNB Turkish version in two sessions. After quality control, reliability analysis was conducted using Intraclass Correlation Coefficients (ICC), corrected for practice effects. Most measures were not significantly different between the sessions and had acceptable ICC values, with several exceptions. Scores were improved considerably for some memory measures, including immediate Facial Memory and Spatial Memory, and for incorrect responses in abstraction and mental flexibility, with correspondingly acceptable ICCs. Test-retest assessment of the Turkish version of the PennCNB shows that it can be used as a reliable real-time measurement of cognitive function in snapshot cross-sectional or longitudinal determinations. Preliminary validity assessment in this normative sample showed expected positive correlations with education level and negative correlations with age. Thus, the Turkish version of the PennCNB can be considered a reliable neuropsychological testing tool in research and clinical practice. Practice effects should be considered, especially when applied in short intervals. Significantly better performances in the retest, beyond practice effect, likely reflect nonlinear improvements in some participants who "learned how to learn" the memory tests or had insight on solving the abstraction and mental flexibility test.

The Effect of Dream Anxiety on Sleep Quality in Inflammatory Bowel Diseases.

INTRODUCTION: Declining sleep quality is a well-known issue in inflammatory bowel disease (IBD), but dream characteristics of patients with IBD and their role in sleep quality are unknown. In this study, we aimed to examine whether and how patients with ulcerative colitis (UC) and Crohn's disease (CD) differ on sleep quality, sleepiness level, and dream anxiety (DA) level compared to healthy controls (HC), controlling for their depressive and anxious tendencies. METHODS: Patients and HCs were enrolled prospectively into the study. The Van DA Scale, Pittsburg Sleep Quality Index, Epworth Sleepiness Scale, Beck Depression Index, and State-Trait Anxiety Inventories were used to assess DA, sleep quality, sleepiness, depression, and anxiety, respectively. RESULTS: Patients with IBD had significantly lower depression (p = 0.004), state anxiety (p = 0.0001), trait anxiety (p = 0.004), and DA (p = 0.0001) than HCs. Although no statistically significant difference in sleep quality was found (p = 0.99), daytime sleepiness was more common in HCs than in IBD patients (p = 0.0001). No statistically significant difference was seen in depression, state anxiety, trait anxiety, DA, sleep quality, and daytime sleepiness between patients with CD and those with UC. No correlation was found between disease activity indices and psychological parameters. CONCLUSION: In contrast to previous studies, this study found lower anxiety and depression levels in patients with IBD than in HCs. Moreover, DA score was higher in HCs. For the first time, we revealed that DA may be one of the factors leading to sleep disturbance in patients with IBD.

α-Lipoic Acid Vaginal Administration Contrasts Inflammation and Preterm Delivery in Rats.

α-Lipoic acid (ALA) is a safe natural molecule involved in the immunomodulation of many physiological processes. Orally administered ALA has been reported to treat several inflammatory pathologies and support pregnancy. Our study aimed at testing ALA vaginal administration in female Wistar rats evaluating its tissue distribution (experiment I), impact on implantation process (experiment II), and effectiveness in contrasting induced preterm birth (experiment III). In experiment I, rats were intravaginally treated with 50 mg/kg or 500 mg/kg ALA, or with a physiologic solution, for 4 days. α-Lipoic acid distribution in uterus and cervical tissues was evaluated by immunohistochemical analyses. In experiment II, rats received intravaginally the above treatments for 5 days, then they were mated and, if pregnant, included in the experiment to evaluate both implantation rate and the content of implantation mediators in uterus tissues. In experiment III, pregnant rats were pretreated with placebo or with vaginal ALA for 4 days and then induced to delivery with mifepristone plus PGE2 on the 19th day of pregnancy. The delivery time was recorded, and the messenger RNA (mRNA) levels of pro-inflammatory cytokines were detected in the uterine tissues by real-time polymerase chain reaction. Immunohistochemistry was also performed. Results showed that vaginal ALA was well absorbed and distributed. The treatment did not affect the implantation process and was able to significantly revert mifepristone plus prostaglandin E2 effects, delaying the timing of delivery and significantly decreasing mRNA synthesis and release of pro-inflammatory cytokines. We provide for the first time new information on vaginal ALA use, even during pregnancy, opening a perspective for further studies.

Mother-Child Interactions of Preterm Toddlers.

INTRODUCTION: We aimed to investigate the mother-toddler relationship in preterm toddlers. METHODS: The sample consisted of 18 mothers and their preterm toddlers (group 1) and 20 mothers and their fullterm toddlers (group 2). Anxiety and depressive symptom levels, attachment pattern, and parental attitudes of mothers and social-emotional problems and developmental level of the toddlers were explored to assess possible confounding factors in the mother-toddler relationship. Two researchers rated the Parent Infant Relationship Global Assessment Scales (PIRGAS). RESULTS: Both the mothers in group 1 and group 2 had similar Beck Depression Inventory (BDI) and State and Trait Anxiety Inventory (STAI) scores. However, the mothers who gave birth before 32 weeks of gestation had higher trait anxiety scores than others (46±2.4 vs. 42.3±5.4, p=0.01). The groups had similar Brief Infant Toddler Social Emotional Assessment Scale (BITSEA) problem and competency scores. The parenting style of group 1 revealed that they had higher scores on the Parenting Attitude Research Instrument (PARI) subscale 5 (excessive discipline) (39.6 vs. 32.1; p=0.02). CONCLUSION: Mother-toddler interaction and attachment security were found to be similar in fullterm and moderately preterm healthy toddlers. Our findings suggest that not the preterm birth itself but the medical, developmental, and/or neurological consequences of prematurity may affect the mother-toddler interaction. To explore the independent effect of prematurity in mother-toddler dyadic relationship, longitudinally designed studies are warranted.

Postoperative psychiatric disorders in general thoracic surgery: incidence, risk factors and outcomes.

OBJECTIVE: Postoperative psychiatric disorders (PPDs) may complicate the post-surgical outcome. We analysed the types, incidences, risk factors and outcomes of the PPDs in non-cardiac thoracic surgery patients. METHODS: All patients (n=100) undergoing major non-cardiac thoracic surgery from January 2004 to March 2005 were investigated prospectively. The diagnosis of PPD was made based on the Diagnosis and Statistical Manual of Mental Disorders. The patients were grouped into two according to the presence (group I) or absence (group II) of PPD. Data on pre-, per- and postoperative factors, and the adverse outcomes were analysed. RESULTS: Eighteen patients (18%) developed PPD, including delirium in 44%, adjustment disorders in 22%, panic attack in 17%, minor depression in 11% and psychosis in 6%. The patients who developed PPD were older (58+/-17 vs 50+/-15 years, p=0.05), had a longer operation time (6+/-1 vs 5+/-2h, p=0.015) and hospital stay (13+/-9 vs 8+/-5 days, p=0.019). The morbidity and mortality rates were not significantly different between the groups (67% vs 46%; 11% vs 1%, respectively). The causative factors in the development of PPD were older age, longer operation time, abnormal serum chemistry values of sodium, potassium, calcium and glucose, hypoalbuminaemia, the presence of the postoperative respiratory distress and infection and blood transfusion (p<0.05). CONCLUSIONS: PPDs are associated with adverse outcomes including a longer hospital stay, and increased morbidity and mortality rates. The identification, detection and elimination of these risk factors are recommended.

End-of-life decisions in the newborn period: attitudes and practices of doctors and nurses.

The aim of our study was to assess the attitudes and practices of doctors and nurses about end-of-life decisions and compare our results with those observed in different European countries. The data was collected from nurses and doctors, using a standardized questionnaire adapted from the EURONIC study. A total of 250 structured questionnaires were delivered, and 135 (77%) of them were accepted for analysis. The end-of-life decision was taken in 39.4% of the hospitals and personal involvement was 40%. Although an ethical committee was present in the hospitals of 61.5% of responders, a written policy was present in only 3.1% of the units. The mean attitude score was 6.5. Seventy-five percent of the contributors agreed that everything possible should be done to ensure a neonate's survival regardless of the prognosis and 65.2% of responders believed that costs of health care should not affect nontreatment decisions. Most of the responders (65.2%) agreed that severe mental disability as an outcome was equal to or worse than death. In patients in whom medical intervention would be futile, or would not offer sufficient benefit to justify the burdens imposed, hospitals should set up a functional ethical committee in order to decide in matters of withholding or withdrawing intervention.

Psychotic depression: a peculiar presentation for multiple sclerosis.

Multiple sclerosis (MS) is frequently associated with a number of different psychiatric syndromes. Solely psychiatric syndrome may be the first clinical presentation of multiple sclerosis. We report a patient whose first attack was psychotic depression. The present case emphasizes that psychiatric symptoms can occur at any time during the course of the disease and, moreover, may be the presenting feature.

The impact of antistigma education on the attitudes of general practitioners regarding schizophrenia.

The aim of this study was to examine the views and attitudes of general practitioners (GP) with respect to schizophrenia, and the changes in their attitudes after antistigma education. A total of 106 GPs working in 71 health institutions were included in the study. A questionnaire of 16 items, focussing on doctors' views and attitudes towards schizophrenia, was applied. Questions were about the views and attitudes of doctors towards general myths related to schizophrenia. Doctors were asked to select one of two responses: 'I agree' or 'I disagree', for statements such as 'schizophrenic patients cannot work' and 'schizophrenic patients are aggressive and dangerous'. After completing the questionnaire, all the GPs were given a single session of antistigma education. The questionnaire was repeated 3 months after training meetings in a subsample of 54 GPs which represented the whole sample in terms of gender, age, and years in medical practice. The authors found statistically significant, positive changes on five items out of the 16 items in the post-test survey when compared to attitudes before training, including items about the treatability of schizophrenia, harmfulness and untrustworthiness of schizophrenic patients. The authors' findings suggest that one antistigma education session, supported by the distribution of related documents, can improve GPs attitudes towards schizophrenia.

Factors associated with postoperative delirium after thoracic surgery.

BACKGROUND: Postoperative delirium is an acute confusional state characterized by fluctuating consciousness and is associated with increased morbidity and mortality. We analyzed the incidence and risk factors of delirium following thoracic surgery. METHODS: All patients (n = 432) who underwent thoracotomy or sternotomy from 1996 to 2003 were analyzed retrospectively. The diagnosis of postoperative delirium was based on Diagnostic and Statistical Manual of Mental Disorders- IV criteria. RESULTS: Postoperative delirium developed in 23 patients (5.32%) between postoperative days 2 to 12 (mean, 4.4 +/- 2.6 days). There were 15 males and 8 females, with a mean age of 59.4 years (24 to 77 years). The delirium group was older (59.4 +/- 14.6 vs 51.3 +/- 15.5 years, p < 0.01) and had a longer operation time than the nondelirious group (5.34 +/- 1.58 vs 4.38 +/- 1.6 hours, p = 0.005). Morbidity and mortality rates were not significantly different between the two groups (56.5% vs 47.1%; 13.0% vs 3.66%, respectively). Univariate analysis showed that the older age, markedly abnormal postoperative levels of sodium, potassium, or glucose, sleep deprivation, operation time, and diabetes mellitus were risk factors (p < 0.05). According to multivariate analyses, four factors were selected as predictive risk factors: (1) markedly abnormal postoperative levels of sodium, potassium, or glucose (p = 0.038); (2) sleep deprivation (p = 0.05); (3) age (p = 0.033); and (4) operation time (p = 0.041). CONCLUSIONS: Postoperative delirium may cause higher morbidity and mortality rates after thoracic surgery. Close postoperative follow-up and early identification of predisposing factors such as older age, sleep deprivation, abnormal postoperative levels of sodium, potassium, or glucose, and longer operation time can prevent occurrence of postoperative delirium.
