RESUMO
BACKGROUND: Delirium is a neurobehavioral syndrome, which is characterized by a fluctuation of mental status, disorientation, confusion and inappropriate behavior, and it is prevalent among hospitalized patients. Recognizing modifiable risk factors of delirium is the key point for improving our preventive strategies and restraining its devastating consequences. This study aimed to identify and investigate various factors predisposing hospitalized patients to develop delirium, focusing mostly on underlying diseases and medications. METHOD: In a prospective, observational trial, we investigated 220 patients who had been admitted to the internal, emergency, surgery and hematology-oncology departments. We employed the Confusion Assessment Method (CAM) questionnaire, The Richmond Agitation Sedation Scale (RASS), the General Practitioner Assessment of Cognition (GPCOG), demographic questionnaire, patient interviews and medical records. Multivariate logistic regression models were used to analyze the predictive value of medications and underlying diseases for daily transition to delirium.; demographics were analyzed using univariate analysis to identify those independently associated with delirium. RESULTS: Two hundred twenty patients were enrolled; the emergency department had the most incident delirium (31.3%), and the surgery section had the least (2.4%); delirium was significantly correlated with older ages and sleep disturbance. Among multiple underlying diseases and the medications evaluated in this study, we found that a history of dementia, neurological diseases and malignancies increases the odds of transition to delirium and the use of anticoagulants decreases the incident delirium. CONCLUSION: Approximately 1 out of 10 overall patients developed delirium; It is important to evaluate underlying diseases and medications more thoroughly in hospitalized patients to assess the risk of delirium.

BACKGROUND: Delirium is prevalent among hospitalised patients, especially in critically ill patients. Preventing delirium by recognising its modifiable risk factors could improve life quality, decrease mortality and restrain its devastating consequences. METHOD: We investigated 50 patients who had been hospitalised in the general ICU and monitored them for developing delirium. We employed CAM and CAM-ICU Scales to assess delirium, RASS score to determine the consciousness level, HADS questionnaire for anxiety and depression, and the demographic data questionnaire. RESULTS: We found that 20% of ICU patients developed delirium and found a meaningful correlation between the incident delirium, older ages, visual impairment, and higher anxiety and depression scores (HADS) of first and second days of hospitalisation. By utilising logistic regression, we found that older ages, visual impairment, higher anxiety and depression scores (HADS) of the first day of hospitalisation were statistically significant to predict the risk model of developing delirium. CONCLUSION: Depressive and anxiety symptoms were associated with higher odds of transitioning to delirium; so, at the admission time, it may be useful to screen patients for the symptoms of affective disorders, particularly, who are at higher risks for developing delirium.

OBJECTIVE: To determine brain functional connectivity (FC), based on the graph theory, in individuals with psychogenic nonepileptic seizures (PNES), in order to better understand the mechanisms underlying this disease. METHODS: Twenty-three patients with PNES and twenty-five healthy control subjects were examined. Alterations in FC within the whole brain were examined using resting-state functional magnetic resonance imaging (MRI). We calculated measures of the nodal degree, a major feature of the graph theory, for all the cortical and subcortical regions in the brain. Pearson correlation was performed to determine the relationship between nodal degree in abnormal brain regions and patient characteristics. RESULTS: The nodal degrees in the right caudate (CAU), left orbital part of the left inferior frontal gyrus (ORBinf), and right paracentral lobule (PCL) were significantly greater (i.e. hyper-connectivity) in individuals with PNES than in healthy control subjects. On the other hand, a lesser nodal degree (i.e. hypo-connectivity) was detected in several other brain regions including the left and right insula (INS), as well as the right putamen (PUT), and right middle occipital gyrus (MOG). CONCLUSION: Our findings suggest that the FC of several major brain regions can be altered in individuals with PNES. Areas with hypo-connectivity may be involved in emotion processing (e.g., INS) and movement regulation (e.g., PUT), whereas areas with hyper-connectivity may play a role in the inhibition of unwanted movements and cognitive processes (e.g., CAU).

OBJECTIVE: To characterize the effective connectivity (EC) between the emotion and motor brain regions in patients with psychogenic nonepileptic seizures (PNES), based on resting-state spectral dynamic causal modeling (spDCM). METHODS: Twenty-three patients with PNES and twenty-five healthy control (HC) subjects underwent resting-state fMRI scanning. The coupling parameters indicating the causal interactions between eight brain regions associated with emotion, executive control, and motion were estimated for both groups, using resting-state fMRI spDCM. RESULTS: Compared to the HC subjects, in patients with PNES: (i) the left insula (INS) and left and right inferior frontal gyri (IFG) are more inhibited by the amygdala (AMYG), anterior cingulate cortex (ACC), and precentral gyrus (PCG); (ii) the left AMYG has greater inhibitory effects on the INS, IFG, dorsolateral prefrontal cortex (DLPFC), PCG, and supplementary motor area (SMA); (iii) the left ACC has more inhibitory effects on the INS and IFG; (iv) the right ACC is more inhibited by the INS and IFG, and has a less inhibitory effect on the SMA and PCG; and (v) the left caudate (CAU) had increased inhibitory effects on the AMYG and IFG and a more excitatory effect on the SMA. CONCLUSION: Our results suggest that in patients with PNES, the emotion-processing regions have inhibitory effects on the executive control areas and motor regions. Our findings may provide further insight into the influence of emotional arousal on functional movements and the underlying mechanisms of involuntary movements during functional seizures. Furthermore, they may suggest that emotion regulation through cognitive behavioral psychotherapies can be a potentially effective treatment modality.

PURPOSE OF REVIEW: This review discusses cultural trends, challenges, and approaches to assessment and treatment of personality traits and disorders. Specific focus include current developments in the Asian, Italian, Iranian, and Australian societies, as well as the process of acculturation, following moves between cultures with the impact on healthy and disordered personality function. RECENT FINDINGS: Each culture with its specific history, dimensions, values, and practices influences and gears the individual and family or group in unique ways that affect personality functioning. Similarly, each culture provides means of protection and assimilation as well as norms for acceptance and denunciations of specific behaviors and personality traits. The diagnosis of personality disorders and their treatment need to take into consideration the individual in the context of the culture and society in which they live. Core personality problems, especially emotion dysregulation and interpersonal functioning are specifically influenced by cultural norms and context.

BACKGROUND: Neuroimaging, immunologic, and pharmacologic studies have emphasized the role of 5-HT2A and 5-HT3A serotonin receptors in the pathophysiology of major depression. AIM: The aim of this study was to measure the relative expression of 5-HT2A and 5-HT3A receptor mRNA in peripheral blood mononuclear cells (PBMCs) of patients with major depressive disorder (MDD). METHOD: 5-HT2A and 5-HT3A receptor mRNA expressions were examined in PBMCs of 25 medication-naïve-patients with MDD, 25 medication-free MDD patients, and 25 healthy controls. 5-HT2A and 5-HT3A receptor mRNA expressions were measured using real-time quantitative PCR. This study evaluated patients' clinical symptoms using the Hamilton Depression Rating Scale-17 items (HDRS) and the Beck Depression Inventory (BDI). RESULTS: Relative 5-HTR2A mRNA expression was significantly higher in PBMCs of all MDD patients when compared with healthy controls (Z = -3.875, p < 0.05). However, there was no significant difference in the relative levels of 5-HTR3A mRNA expression in PBMCs of all MDD patients when compared with healthy controls (Z = -1.328, p > 0.05). MDD patients showed significant correlations between 5-HTR2A mRNA expression and HDRS scores (rs = 0.902, p < 0.001) and BDI scores (rs = 0.878, p < 0.001). CONCLUSION: This study showed that depressed patients, irrespective of treatment, have higher 5-HTR2A mRNA levels in PBMCs than healthy subjects. It also provided evidence that 5-HTR2A mRNA levels in PBMCs of MDD patients could be associated with the severity of depression and the duration of the illness.

BACKGROUND: The antidepressant effect of omega-3 fatty acids has been described in the non-HIV population. The effect of omega-3 fatty acid supplementation on the mood status of HIV-positive patients has not been evaluated yet. OBJECTIVE: In this study, the effect of omega-3 fatty acids on depressive symptoms was evaluated in HIV-positive individuals. METHOD: A total of 100 HIV-positive patients with Beck Depression Score ≥16, were assigned to receive either omega-3 fatty acids or placebo twice daily for 8 weeks. Depressive symptoms of each participant were evaluated at baseline (month 0) and at the end of months 1 and 2 of the study. Beck Depression Inventory Second Edition, depression subscale of the Hospital Anxiety and Depression Scale, and Patient Health Questionnaire were used for assessment of depressive symptoms. RESULTS: Reduction in mean ± SD of all depression scores during the study period was statistically significant within the omega-3 group and when compared with the placebo group (for both comparisons, P < 0.001). Also, the mean differences of all depression scores were decreased significantly during the intervals: months 0, 1, and 2 (P < 0.001 for all comparisons). Among the participants, 7 (7%) and 4 (4%) patients in the omega-3 and the placebo group, respectively, experienced mild gastrointestinal problems, but the incidence of adverse drug reactions related to the interventions was not statistically different between the groups (P = 0.09). CONCLUSION: Omega-3 fatty acids improved depressive symptoms in HIV-positive individuals without any significant adverse reaction.

BACKGROUND: Postoperative delirium is a common neurobehavioral complication after major surgeries. There is no conclusive approach for prevention of delirium in these patients. OBJECTIVE: In this study, efficacy of cyproheptadine for prevention of postoperative delirium was evaluated. METHODS: Delirium status of surgical patients was evaluated postoperatively at the time of admission to the intensive care unit (ICU) using the Confusion Assessment Method (CAM-ICU) scale. Patients without delirium were assigned to the cyproheptadine or placebo group based on the simple randomization method. Patients received cyproheptadine or placebo tablet at a dose of 4 mg 3 times per day for 7 days. Patients were monitored daily for incidence of delirium. RESULTS: Changes in the incidence rates of delirium over time during the study phase (P = 0.04) and between the groups showed statistically significant differences (P = 0.029). However, severity of delirium was not significantly different between the cyproheptadine and placebo groups during the study period. CONCLUSION: It seems that cyproheptadine with its diverse effects can be a potential option for prevention of postoperative delirium. In this pilot study, cyproheptadine significantly decreased the incidence but not severity of postoperative delirium.

BACKGROUND: The antidepressive effect of pioglitazone has been noted in patients with major depressive disorder in absence of metabolic syndrome. This study was conducted to evaluate the safety and efficacy of pioglitazone in patients with bipolar depression without concomitant metabolic syndrome or diabetes. METHOD: Forty-eight outpatients with the diagnosis of bipolar I disorder and a major depressive episode participated in a parallel, randomized, double-blind, placebo-controlled trial, and 44 patients underwent 6-week treatment with either pioglitazone (30 mg/day) or placebo as an adjunctive treatment to lithium. Therapeutic serum lithium levels of 0.6-0.8 mEq/L were required for two or more consecutive weeks immediately before starting pioglitazone and during the 6-week study. Patients were evaluated using Hamilton Depression Rating Scale (HDRS) and Young Mania Rating Scale (YMRS) at baseline and weeks 1, 2, 4, and 6. The primary outcome was to evaluate the efficacy of pioglitazone in improving the depressive symptoms. RESULT: General linear model repeated measures showed significant effect for time × treatment interaction on the HDRS scores [F(2.78, 116.65) = 4.77, P = .005]. Significantly greater reduction was observed in HDRS scores in the pioglitazone group than the placebo group from baseline HDRS score at weeks 2, 4, and 6, P = .003, .006, and .006, respectively. No serious adverse event was observed. CONCLUSION: This study showed that pioglitazone could be a tolerable and effective adjunctive therapy for improving depressive symptoms in bipolar disorder without type 2 diabetes or metabolic syndrome.

Childbirth is a unique experience in women's life. Various factors including human and non-human environment are involved in shaping the experience of childbirth.This study investigated the role of the environment on the psychological birth trauma from the perceptions of Iranian mothers. A qualitative descriptive study was conducted from September 2011 to February 2012, using audiotaped interviews with 23 Iranian women recruited from Tehran and Isfahan. The interviews were transcribed verbatim and analysed using the content analysis. Two themes were extracted from the data: human and non-human environment; and several categories also emerged from the data, which are communication with mother, awareness of mother's needs, support for mother, medical clinical competence, professional responsibility, hospital's physical structure, hospital's equipment, routine care in hospital and rules governing the hospital's environment, respectively. Considering the significant role of environment in psychological birth trauma of the mother, an appropriate intervention must be developed to enhance both human and non-human environment in order to reduce the psychological birth trauma.

There is a growing body of evidence that suggests a positive role for religious involvement in physical and mental health. Studies have shown that attitudes of physicians toward religion affect their relationship with patients and their medical decisions, and in this way may ultimately affect treatment outcomes. Attitudes of nurses toward religion could also influence whether or not they address patients' unmet spiritual needs. To assess attitudes of physicians and nurses toward religion and how these attitudes vary by education level and demographic characteristics, a total of 800 physicians, medical students, and nurses from some of the largest hospitals in Tehran, Iran, were approached, of whom 720 completed questionnaires (148 nurses, 572 medical students and physicians). The survey questionnaire included the Duke University Religion Index (DUREL), Hoge Intrinsic Religiosity Scale, a brief measure of Negative Religious Coping (NRCOPE), and the brief Trust/Mistrust in God Scale. Religious attitudes and practices were compared between physicians (medical students and physicians) and nurses. Regression analysis revealed that except for intrinsic religiosity, physicians were not less religious than nurses on any other dimension of religiosity. Training level (year of training) was a predictor of religiosity, with those having less training being the most religious. The findings suggest that there are few religious differences between nurses and physicians in Iran. However, religiosity may become less as the training level increases. Lack of emphasis in training on the important role that religion plays in health care may result in a decrease in religious involvement and the development of negative attitudes toward religion over time (displaced by a focus on the technological aspects of health care).

Aim: The aim of this study was to evaluate the short-term and long-term effects of routine repetitive transcranial magnetic stimulation (rTMS) on the sleep duration, depressive symptoms, and quality of life of patients with treatment-resistant depression (TRD). Methods: In this prospective cohort study, 25 participants with TRD were assessed using the Insomnia Severity Index (ISI) and four sleep duration components of the Pittsburgh Sleep Quality Index (PSQI). Depression severity was measured with Hamilton's Depression Rating Scale (HDRS) and Beck's Depression Inventory (BDI-II), and patient-perceived quality of life with the 36-Item Short-Form Survey (SF-36). All of these measures were evaluated at baseline (T0), and immediately (T1), 6 weeks (T2), and 12 weeks (T3) after the end of intervention. Results: At T1 endpoint, HDRS, BDI, SF-36, ISI, and three PSQI items (time to wake up, time taken to fall asleep, and Real Sleep Time) significantly improved, though these gains were reduced at follow-up endpoints (T2 and T3). Adjusting for confounders (age, sex, occupational status, BMI, and hypnotic medication) revealed that only improvements in HDRS, BDI, and time taken to fall asleep at T1 remained statistically significant. Linear regression analyses showed no significant association between reduced time taken to fall asleep and depression symptoms, suggesting rTMS can independently enhance this parameter, irrespective of depression resolution. Conclusion: Routine rTMS therapy can potentially enhance sleep duration in TRD individuals, alongside improved depressive symptoms and quality of life. However, these benefits tend to decrease over long-term follow-up, emphasizing a more pronounced short-term efficacy of rTMS.
RESUMO
Canine distemper virus (CDV) is responsible for high morbidity and mortality in dogs worldwide. Epidemiological study of canine distemper can help to control and treat the disease in any area. This study aimed to investigate the prevalence of CDV in dogs referred to the Veterinary Hospital from September 23, 2018 to September 22, 2019. Dogs with at least two clinical signs of canine distemper underwent blood tests, rapid test kit from the eye and cerebrospinal fluid (CSF), and RT-PCR from whole blood and/or CSF samples. Out of 1212 referred dogs, 112 dogs were suspected to have canine distemper of which 90 underwent RT-PCR and rapid test kits. The disease prevalence was 4.04% (49/1212) and 7.44% (49/659) according to the total number of referring dogs and number of referring sick dogs, respectively. The distemper fatality rate was 69.57% (32/46). Seventy percent of distemper positive cases were under 12 months old and 52.08% were under 6 months old. Female dogs were more susceptible than males; however, the fatality rate of males was more than females. Of distemper positive dogs, 91.84% were unvaccinated. The highest prevalence (71.43%) of dogs diagnosed with CDV occurred during the cold seasons. It is concluded that canine distemper is endemic in the geographical area of Mashhad and its prevalence rate in dogs referred to the Veterinary Hospital of Ferdowsi University of Mashhad is 4.04% and its fatality rate is 69.57%. This indicates that a significant number of dogs may die if they develop distemper despite treatment.
RESUMO
The therapeutic effect of deep brain stimulation on patients with treatment-resistant depression is strongly dependent on the connectivity of the stimulation region with other regions associated with depression. The aims of this study are to characterize the effective connectivity between the brain regions playing important roles in depression and further investigate the underlying pathophysiological mechanisms of treatment-resistant depression and the mechanisms involving deep brain stimulation. Thirty-three individuals with treatment-resistant depression and 29 healthy control subjects were examined. All subjects underwent resting-state functional MRI scanning. The coupling parameters reflecting the causal interactions among deep brain stimulation targets and medial prefrontal cortex were estimated using spectral dynamic causal modelling. Our results showed that compared to the healthy control subjects, in the left hemisphere of treatment-resistant depression patients, the nucleus accumbens was inhibited by the inferior thalamic peduncle and excited the ventral caudate and the subcallosal cingulate gyrus, which in turn excited the lateral habenula. In the right hemisphere, the lateral habenula inhibited the ventral caudate and the nucleus accumbens, both of which inhibited the inferior thalamic peduncle, which in turn inhibited the cingulate gyrus. The ventral caudate excited the lateral habenula and the cingulate gyrus, which excited the medial prefrontal cortex. Furthermore, these effective connectivity links varied between males and females, and the left and right hemispheres. Our findings suggest that intrinsic excitatory/inhibitory connections between deep brain stimulation targets are impaired in treatment-resistant depression patients, and that these connections are sex dependent and hemispherically lateralized. This knowledge can help to better understand the underlying mechanisms of treatment-resistant depression, and along with tractography, structural imaging, and other relevant clinical information, may assist to determine the appropriate region for deep brain stimulation therapy in each treatment-resistant depression patient.
RESUMO
Objective: Psychoses of epilepsy usually have an acute onset, accompanied by brief symptom duration and a risk of recurrence. Managing these conditions can be challenging due to the potential for seizures associated with certain antipsychotic medications, as well as exacerbating psychosis resulting from some antiepileptic medications. Our objective in this study was to assess the occurrence of psychosis among patients with epilepsy, as well as identify the factors linked to the presence and severity of psychosis in this population. Method : In this study, we included a total of 514 subjects diagnosed with epilepsy referring to our neuropsychiatry clinic affiliated with Tehran University of Medical Sciences from April 2011 to December 2021, among whom 57 patients showed psychotic presentations. We compared baseline and clinical characteristics between patients with psychosis of epilepsy and non-psychosis patients who also had epilepsy. Results: Marital status was the sole demographic factor that displayed a statistically significant difference between the psychosis and non-psychosis groups (P = 0.019). There was no significant difference observed between the two groups regarding family history of epilepsy and age at the onset of the epilepsy. Patients with psychosis experienced significantly more frequent seizures and generalized type (P < 0.001). Participants were matched for demographics and other clinical factors between the refractory and controlled psychosis groups, except for the psychosis frequency (P = 0.007). The type of epilepsy was significantly associated with psychosis when adjusted for the covariates (P < 0.001). Conclusion: Patients with psychosis of epilepsy experienced more episodes of epilepsy than non-psychotics. We identified generalized epilepsy as an independent risk factor for the development of psychosis. Additional cohorts are warranted to explore the factors associated with epilepsy-related psychosis across diverse populations.
RESUMO
BACKGROUND: Awake craniotomy (AC) is considered to achieve maximal safe resection of language eloquent gliomas. Impact of AC on the psychological status of patients (mainly anxiety, and post-traumatic stress disorder [PTSD]) is a potential concern. Despite the studies reporting the early postoperative patient's perception after AC, this study has been performed to quantitatively evaluate the long-term influence of AC on the level of anxiety/depression after surgery. METHODS: Patients who underwent AC for suspected language eloquent high-grade glioma were enrolled in this study. The anxiety, depression and PTSD of the patients were evaluated via hospital anxiety and depression scale (HADS) one week before and 1 and 6 months after the operation. PTSD symptoms were assessed according to the DSM-V checklist and confirmed by a structured clinical interview for DSM-V. RESULTS: Twenty-eight patients (22 men, six women) with the mean age of 39.2 years were enrolled. The mean preoperative depressive and anxiety score was 4.9±5.9 and 7.7±5.8 respectively. One month after surgery they were 6±4.9 and 7.4±6.2 and at 6 months' follow-up 5.5±5.1 and 5.4±4.2 respectively. There was no statistically significant trend for alterations of the anxiety/depression levels before and after surgery. Female patients, those suspected to have glioblastoma and patients presenting with speech disturbance had remarkably higher preoperative anxiety levels. Three patients had PTSD symptoms 3 months after AC while at 6 months there was no indication of PTSD. The decremental trend of PTSD score within 6 months was statistically significant. CONCLUSIONS: Judicious application of AC is not associated with an escalation of the anxiety/depression level among the patients. Even patients with high preoperative anxiety levels could be managed with AC without severe psychological deterioration.

PURPOSE: This study was conducted to determine the correlation between preeclampsia and depression. METHODS: Participants in this study included 156 cases with preeclampsia and 156 controls without any history of preeclampsia who were all newly admitted to antepartum wards, emergency room wards, and labor and delivery wards of the study hospitals (Valieasr, Shariatti, Mirza Koochak Khan, Shahid Akbar Abadi, Baharloo and Arash). They consented and completed a questionnaire on demographic characteristics, obstetric, delivery and infant information and Patient Health Questionnaire (PHQ-9) to assess their depression status. Data were analyzed through independent t test, Mann-Whitney U test, Chi-squared test, Fisher's exact test and multiple regression by SPSS and STATA. RESULTS: Moderate to severe depression was found in 31.2% of the cases and 24.8% of the controls. Women with no depression in comparison with women with mild depression had a 1.81-fold (95% CI 1.05-3.14; P = 0.03) increased risk of preeclampsia, while moderate to severe depression correlated with a 2.52-fold increase (95% CI 1.05-6.02; P = 0.03) after adjustment of the probable confounding variables. DISCUSSION: With regard to the high prevalence of moderate to severe depression and its association with preeclampsia, our findings support and suggest efforts for screening depression among pregnant women and appropriate educational studies for mental and psychological problems during pregnancy.

Canine Distemper Virus (CDV) is the cause of a highly lethal infectious disease affecting a broad range of carnivores. Despite using various treatments, there is still no effective treatment, especially in the neurological form of distemper. The aim of this study was to evaluate the therapeutic effect of injecting Newcastle disease vaccine into the subarachnoid space of dogs with neurological form of distemper. The dogs that had symptoms of nervous distemper, particularly myoclonus, were included in the plan. After anesthetizing of dogs, 0.10 to 1.00 mL of cerebrospinal fluid (CSF) were removed and, 0.10 to 0.50 mL of the prepared Newcastle solution were injected into their subarachnoid space. Another 0.50 to 1.00 mL of normal saline was then injected to remove the needle from the vaccine. The live attenuated LaSota or B1 vaccine was used in this study. Rapid kit tests and reverse transcription polymerase chain reaction (RT-PCR) assays were used to diagnose of the disease. Dogs were monitored for up to 3 to 24 months during that time they were evaluated for improvement or worsening of clinical symptoms. Out of nine dogs in which distemper were diagnosed with different tests, one dog recovered completely and another dog recovered greatly. Therefore, the overall recovery rate was 22.20%. It is concluded that administration of Newcastle vaccine into the subarachnoid space of dogs with nervous distemper causes at least 22.20% improvement and does not cause specific side effects and can be used to treat affected dogs.
RESUMO
BACKGROUND: Accurate diagnosis of canine distemper (CD), a highly contagious and acute viral disease, cannot be made solely based on clinical signs and haematological findings, but serological and molecular methods compatible with clinical signs are also required. The type of sample and method of tissue sampling are also very important. Sometimes in chronic cases, the canine distemper virus (CDV) may not be detected in blood and conjunctival specimens but can be detected in cerebrospinal fluid (CSF). OBJECTIVES: The aim of this study was to evaluate and compare the suitability of CSF samples with whole blood and conjunctival samples in the detection of CDV. METHODS: The CDV was detected in CSF, whole blood and mucosal specimens in 20 dogs with obvious neurological with or without systemic signs congruous with CD by RT-PCR and rapid immunochromatographic (IC) antigen test kit assays. RESULTS: Rapid kit results were positive for mucosal swabs in 10 cases (50%) and for CSF in 17 cases (85%); RT-PCR results from whole blood were positive in 11 cases (55%) and from CSF in 16 cases (80%). CONCLUSIONS: Our results revealed that dogs with neurological signs showing simultaneous or recent systemic symptoms, whole blood, CSF and mucosal swabs are suitable for the diagnosis of CDV by RT-PCR and rapid IC antigen test kits, but dogs with neurological symptoms that are systematically asymptomatic or have had systemic signs for a long time, whole blood and mucosal swabs are not good samples while CSF is a good one.

BACKGROUND: Covid-19 patients suffer from psychiatric disorders too. The present study was designed to investigate the rate of psychiatric consultation requests in a general hospital. Reasons for consultation requests, types of psychiatric diagnoses, and factors in consultation requests were also investigated. METHODS: This cross-sectional study included all patients admitted with Covid-19 and referred to psychiatric consultation service in a major Covid-19 center in Tehran, Iran (2020). After acceing patients' electronic files, records of patients' demographic information, positive psychiatric symptoms, past psychiatric history and DSM5 diagnoses were made. Statistical analyses were done in SPSS 26 using descriptive statistics and chi-square and Fisher's exact test (p<0.05). RESULTS: Out of 1791 Covid-19 hospitalized patients, 132 patients (7.3%) had been referred to psychiatric consultation service. The most common reason for requests were restlessness and aggression (23.5%). Meanwhile, 92.4% of the patients were diagnosed to suffer from at least one psychiatric disorder including insomnia (64%), delirium (30.3%), anxiety due to hypoxia (15.3%) and generalized anxiety disorder (10.6%). CONCLUSION: Although studies report a high prevalence of psychiatric disorders in Covid-19 patients, requests for psychiatric consultations and consideration of psychiatric disorders are still remarkably low. The most common disorders appeared to be insomnia, delirium and anxiety.
