The Relationship

Background: Dissociative symptoms have been reported to result from issues such as substance use. However, there is limited knowledge on the relationship between methamphetamine use and dissociative symptoms, and only a few studies have been conducted on this issue. Objectives: Given little knowledge on the relationship between methamphetamine use and dissociative symptoms, in particular dissociative disorders, the present study was done to investigate the prevalence of dissociative experiences and dissociative disorders in methamphetamine users in Shahid Beheshti hospital of Kerman City, Kerman Province, Iran. Methods: In this descriptive cross-sectional study, two groups of subjects, including methamphetamine users (N = 50) and controls (N = 51), were randomly selected from the individuals referring to Shahid-Beheshti Hospital, Kerman City, from September 2016 to March 2018. After validating the diagnosis of methamphetamine use via methamphetamine positive-urine test, the Dissociative Experiences Scale (DES) and dissociative disorders interview schedule-DSM5 (DDIS) were employed to assess dissociative experiences and disorders, respectively. Next, the Positive and Negative Syndrome Scale (PANSS) was utilized for the determination of positive and negative symptoms of psychosis in the case group. Finally, the chi-square test and t test were applied for comparing the study groups using SPSS version 20 software. Results: Our findings revealed that the mean score of dissociative symptoms was 15.3 in methamphetamine users. The mean score of depersonalization/derealization subscale of DES, as a dissociative experience, was higher in the case group (P < 0.01). The experience of possession, as a dissociative experience, was recorded in 17 methamphetamine users, while 18 (36%) methamphetamine users were diagnosed with dissociative disorder. Furthermore, a significant correlation was found between the DES score and positive symptoms in methamphetamine users (P < 0.05). Conclusions: According to the findings of the present study, it can be concluded that methamphetamine induces dissociative psychosis in methamphetamine users.

Inpatient Population

Objective This study attempted to estimate the prevalence of dissociative symptoms and disorders in a Canadian adult psychiatric inpatient population and also attempted to determine the extent to which dissociative disorders were recognized by the attending clinical staff. Method All appropriate and consenting adult psychiatric inpatients at the Kingston Psychiatric Hospital in Kingston, Ontario, were given the Dissociative Experiences Scale. Patients scoring 25 or greater were interviewed with the Dissociative Disorders Interview Schedule and the Structured Clinical Interview for DSM-IV Dissociative Disorders. Admission or discharge diagnoses data were used to determine whether or not dissociative disorders were being recognized. Results A total of 48 patients completed the Dissociative Experiences Scale and 14 (29%) scored 25 or greater. The prevalence of dissociative disorders in this hospital population was estimated to be 17%. Dissociative identity disorder was found in six percent, dissociative amnesia in eight percent and dissociative disorder not otherwise specified in two percent of the population. These disorders tended to be under-recognized. Conclusion Research on more extensive populations is required to establish the true prevalence of dissociative symptoms and disorders in psychiatric inpatients.

Background: Pseudo exfoliation syndrome (PXS) widely in world occurred with various prevalence rate and its risk factor has main role in rising IOP and glaucoma. The aim of this study was to evaluate the relationship between PXS and its associations with elevation of IOP/Glaucoma.Methods: This is a cohort study that has been done on 144 patients of aged 50 and older referred to clinic of ophthalmology which was examined to the PXS depositions. PXS was diagnosed by slit lamp and a control group select matching with case group without PXS. All patients underwent a comprehensive ophthalmic evaluation by slit lamp and dilated pupil fundus for visual acuity, refraction, Tonometry and Gonioscopy.Results: Out of 144 eyes of control group, 112 (77.8%) had PXS depositions. There was a significant increase in number of PXS involved eyes with age and the frequency of disease in men was higher than women. Out of 72 patients, 40 (55.5%) patients were bilaterally and 32 (44.5%) patients were unilaterally involved. The mean of IOP in eyes with PXS with 17.9±8.9 was significantly higher than eyes without PXS with 14.5±2.9.Conclusions: PXS sediments are an important risk factor for increased IOP and glaucoma in our area and patients with PXS should be followed in term of IOP.

The Relationship

Abstract Evidence suggests that dissociation is associated with psychotic experiences, particularly hallucinations, but also other symptoms. However, until now, symptom-specific relationships with dissociation have not been comprehensively synthesized. This is the first prospectively registered (CRD42017058214) meta-analysis to quantify the magnitude of association between dissociative experiences and all symptoms of psychosis. MEDLINE, PsycINFO, PubMed, and Scopus databases were searched using exhaustive terms denoting dissociation and psychotic symptoms. We included both nonclinical (58 studies; 16 557 participants) and clinical (46 studies; 3879 patient participants) samples and evaluated study quality. Ninety-three eligible articles considering 20 436 participants were retained for analysis. There was a robust association between dissociation and clinical and nonclinical positive psychotic symptoms (r = .437; 95%CI: .386 −.486), with the observed effect larger in nonclinical studies. Symptom-specific associations were also evident across clinical and nonclinical studies, and included significant summary effects for hallucinations (r = .461; 95%CI: .386 −.531), delusions (r = .418; 95%CI: .370 −.464), paranoia (r = .447; 95%CI: .393 −.499), and disorganization (r = .346; 95%CI: .249 −.436). Associations with negative symptoms were small and, in some cases, not significant. Overall, these findings confirm that dissociative phenomena are not only robustly related to hallucinations but also to multiple positive symptoms, and less robustly related to negative symptoms. Our findings are consistent with proposals that suggest certain psychotic symptoms might be better conceptualized as dissociative in nature and support the development of interventions targeting dissociation in formulating and treating psychotic experiences.

SummaryIn a collaborative trial of eleven laboratories which was performed mainly within the framework of the European Community Bureau of Reference (BCR), a second reference material for thromboplastin, rabbit, plain, was calibrated against its predecessor RBT/79. This second reference material (coded CRM 149R) has a mean International Sensitivity Index (ISI) of 1.343 with a standard error of the mean of 0.035. The standard error of the ISI was determined by combination of the standard errors of the ISI of RBT/79 and the slope of the calibration line in this trial.The BCR reference material for thromboplastin, human, plain (coded BCT/099) was also included in this trial for assessment of the long-term stability of the relationship with RBT/79. The results indicated that this relationship has not changed over a period of 8 years. The interlaboratory variation of the slope of the relationship between CRM 149R and RBT/79 was significantly lower than the variation of the slope of the relationship between BCT/099 and RBT/79. In addition to the manual technique, a semi-automatic coagulometer according to Schnitger & Gross was used to determine prothrombin times with CRM 149R. The mean ISI of CRM 149R was not affected by replacement of the manual technique by this particular coagulometer.Two lyophilized plasmas were included in this trial. The mean slope of relationship between RBT/79 and CRM 149R based on the two lyophilized plasmas was the same as the corresponding slope based on fresh plasmas. Tlowever, the mean slope of relationship between RBT/79 and BCT/099 based on the two lyophilized plasmas was 4.9% higher than the mean slope based on fresh plasmas. Thus, the use of these lyophilized plasmas induced a small but significant bias in the slope of relationship between these thromboplastins of different species.

Purpose: i) To determine the relationship between the cardiac biomarkers ST2 and NT-proBNP with ejection fraction (EF) in heart failure (HF) patients. ii) Assess whether a superiority existed between the aforementioned cardiac markers in diagnosing the HF with reduced EF. iii) Determine the efficacy of both biomarkers in predicting a 30-day cardiovascular event and rehospitalization in patients with HF with reduced EF iv) To assess the influence of age, gender, BMI, anaemia and renal failure on the ST2 and NT-proBNP levels. Design and Methods: A prospective double-blind study was conducted to obtain data from a sample of 64 cardiology patients. A blood sample was collected to test for ST2 and NT-proBNP. An echocardiogram (to obtain EF value), electrocardiogram and questionnaire were also obtained. Results: Of the 64 patients enrolled, 59.4% of the population had an EF less than 40%. At the end of the 30- day period, 7 patients were warded, 37 were not warded, one died and 17 were non respondent. Both biomarkers were efficacious at diagnosing HF with a reduced EF. However, neither of them were efficacious in predicting 30-day rehospitalization. The mean NT-proBNP values being: not rehospitalized (2114.7486) and 30 day rehospitalization (1008.42860) and the mean ST2 values being: not rehospitalized (336.1975), and 30-day rehospitalization. (281.9657). Conclusion: Neither ST2 or NT-proBNP was efficacious in predicting the short- term prognosis in HF with reduced EF. Both however were successful at confirming the diagnosis of HF in HF patients with reduced EF.

Background: Diabetes mellitus (DM) is a common metabolic disease worldwide and has many complications. The vascular events are the major complication of DM that have an important effect on mortality and disability. The physical activity (PA) enhances the vascular function by several pathways. The aim of this study was to evaluation of the relationship between PA and vascular diseases in patients with DM.Materials and Methods: This research was performed as the case-control study that was extracted from a prospective epidemiological research study in Iran (PERSIAN). The patients with type 2 DM more than six months defined as case group and the non-DM subjects in control group with ratio 1:2, and both groups were matched in the term of age and sex. The MET score was used to evaluate the level of PA and blood glucose, lipid profile, body mass index, overweight, dyslipidemia, glomerular filtration rate, myocardial infarction (MI), unstable angina, and stroke.Results: Overall, 1242 patients with DM were extracted, and 2484 non-diabetic subjects were investigated. In the case group, 355(28.6 %) and 887(71.4%) were men and women, respectively, the and 710 (28.6%) men and 1774(71.4%) women in control group. The mean MET score was 30 and 40.97 in the DM and non-DM groups, respectively (P˂0.001). The frequency of MI, stroke, and cardiac ischemia were 44 (3.5%), 37 (3%), and 267 (21.5%), respectively in DM group, and 54 (2.2%), 43 (1.7%), and 389 (15.7%), respectively in non-DM group.Conclusion: The incidence of vascular events associated with PA level in patients with DM and adherence to regular PA reduce the vascular events and DM complications.

Positive And Negative Symptoms

SummaryMost investigators concur that schizophrenia is probably a heterogeneous group of disorders that share the common features of psychotic symptoms, partial response to neuroleptics, and a relatively poor outcome. The subdivision of schizophrenia into two subtypes, positive versus negative, has achieved wide acceptance throughout the world during recent years. This distinction has heuristic and theoretical appeal because it unites phenomenology, pathophysiology, and etiology into a single comprehensive hypothesis.In spite of its wide appeal, the distinction has a number of problems. These include the failure to distinguish between symptom syndromes and diseases; failure to deal with the mixed patient; failure to take longitudinal course into account; and failure to address conceptually and methodologically the distinction between positive and negative symptoms.This paper focuses primarily on the conceptual basis for two instruments designed to measure positive and negative symptoms, the Scale for the Assessment of Negative Symptoms (SANS) and the Scale for the Assessment of Positive Symptoms (SAPS), originally described in 1982. Since their description, these scales have been used in a variety of other centers. These scales are based on the hypothesis that negative symptoms represent a deficit or diminution in normal psychological functions wliile positive symptoms represent an excess or distortion of normal functions. Reliability data are now available from Italy, Spain, and Japan which suggest that these scales can be used reliably in cultural settings outside the United States. The results of these studies are summarized in this paper. In addition, a replication study involving a new sample of 117 schizophrenics collected at the University of Iowa is described. In this second study of the SANS and SAPS, internal consistency is found to be quite high in the SANS. Thus negative symptoms appear to be more internally correlated with one another than are positive symptoms. The implications of this result are discussed. A principal components analysis is used to explore the relationship between positive and negative symptoms. While the study reported in 1982 suggested that positive and negative symptoms are negatively correlated, in the present study they appear to be uncorrelated. Overall, the results suggest that the SANS and SAPS are useful comprehensive instruments for the evaluation of positive and negative symptoms. The relationship between these symptoms and external validators such as cognitive functioning or CT scan abnormalities will be reported in a subsequent investigation.

AbstractThis study aimed to investigate the relationship between autofluorescence (AF) signal measured with ultra-wide field imaging and visual functions in patients with cone-rod dystrophy (CORD). A retrospective chart review was performed for CORD patients. We performed the visual field test and fundus autofluorescence (FAF) measurement and visualized retinal structures with optical coherence tomography (OCT) on the same day. Using binarised FAF images, we identified a low FAF area ratio (LFAR: low FAF/30°). Relationships between age and logMAR visual acuity (VA), central retinal thickness (CRT), central choroidal thickness (CCT), mean deviation (MD) value, and LFAR were investigated. Thirty-seven eyes of 21 CORD patients (8 men and 13 women) were enrolled. The mean patient age was 49.8 years. LogMAR VA and MD were 0.52 ± 0.47 and − 17.91 ± 10.59 dB, respectively. There was a significant relationship between logMAR VA and MD (p = 0.001). LogMAR VA significantly correlated with CRT (p = 0.006) but not with other parameters. Conversely, univariate analysis suggested a significant relationship between MD and LFAR (p = 0.001). In the multivariate analysis, LFAR was significantly associated with MD (p = 0.002). In conclusion, it is useful to measure the low FAF area in patients with CORD. The AF measurement reflects the visual field deterioration but not VA in CORD.
