Everyday life for patients with schizophrenia and severely impaired social functioning.

Background: A structure of everyday life creates routines and a sense of familiarity, which provides a recognizable basis for being and acting in the world. A structure of everyday life reduces stress, and daily stress has consistently been associated with higher levels of psychiatric symptoms. Little is known about how patients with schizophrenia and severe social impairment structure their lives. Thus, we aimed to explore the everyday lives of this group of patients, looking for structuring elements. Methods: In this qualitative study, we included patients diagnosed with schizophrenia who were either homeless or had difficulties reporting for treatment and, thus, needed treatment from an outreach team. Results: 17 participants were included in the study. We found only few structuring elements across all participants in the qualitative analyses. We identified five themes in our sample that serve as structuring elements in the everyday life: social interactions, volunteering to assist with basic tasks, self-initiated routines such as going for a walk daily, exoskeleton (structure provided by others), and having pets. None of the participants reported much activity during the day, and for most of them, social interactions were minimal. Discussion: All the participants had very little structure and routines in their everyday life. The shelters provided the homeless participants with some structuring elements, whereas the domiciled participants had no external structuring elements. The findings have important implications for psychosocial treatment of severe social impairment in schizophrenia. The lack of structure in these patients' everyday lives highlights the need for targeted interventions that could facilitate such structures and guide social involvement and personal recovery.

Characterization of substance use in homeless patients with mental disorders.

BACKGROUND: In Denmark, 42% of homeless people suffer from dual diagnosis, i.e. the co-occurrence of a substance use of alcohol and/or illegal substances and another psychiatric disorder. Dual diagnosis homeless patients often cause differential diagnostic difficulties and fail to receive effective treatment. A solid grasp of the role of substance use in these patients may inform the diagnostic decision and contribute to improve their treatment. Today, knowledge of these issues remains scarce. The purpose of this study was to explore substance use in homeless patients with mental disorders and their subjective perspectives on their substance use. METHODS: 44 homeless dual diagnosis patients were included in the study. They were examined in interviews focusing on their substance use and their subjective perspective on their substance use. RESULTS: The most frequently used substances were cannabinoids (70.5%) and alcohol (45.5%), followed by cocaine, sedative/hypnotics, and amphetamine. The finding suggests that substance use in dual diagnosis homeless patients is a complex phenomenon with most patients (56.8%) using multiple substances. While substance use seems to contribute to keep the patients homeless, substance use was also reported to play an important role in coping with life on the streets by offering social contact and some relief from a desperate situation. CONCLUSION: Substance use, mental disorder, and homelessness seem to be closely entangled, reinforcing each other and making it difficult to help these vulnerable patients. Diagnostic overshadowing may cause delays in adequate diagnosis and treatment of this group of patients.

Pubofemoral distances correlate to acetabular morphology and sonological instability in screening for hip dysplasia.

Aims: The present study seeks to investigate the correlation of pubofemoral distances (PFD) to α angles, and hip displaceability status, defined as femoral head coverage (FHC) or FHC during manual provocation of the newborn hip < 50%. Methods: We retrospectively included all newborns referred for ultrasound screening at our institution based on primary risk factor, clinical, and PFD screening. α angles, PFD, FHC, and FHC at follow-up ultrasound for referred newborns were measured and compared using scatter plots, linear regression, paired t-test, and box-plots. Results: We included 2,735 newborns, of whom 754 received a follow-up hip ultrasound within six weeks of age. After exclusion, 1,500 hips were included for analysis. Sex distribution was 372 male and 380 female, and the mean age at examination was 36.6 days (4 to 87). We found a negative linear correlation of PFD to α angles (p < 0.001), FHC (p < 0.001), and FHC during provocation (p < 0.001) with a 1 mm increase in PFD corresponding to a -2.1° (95% confidence interval (CI) -2.3 to -1.9) change in α angle and a -3.4% (95% CI -3.7 to -3.0) change in FHC and a -6.0% (-6.6 to -5.5) change in FHC during provocation. The PFD was significantly higher with increasing Graf types and in displaceable hips (p < 0.001). Conclusion: PFD is strongly correlated to both α angles and hip displaceability, as measured by FHC and FHC during provocation, in ultrasound of newborn hips. The PFD increases as the hips become more dysplastic and/or displaceable.

Birthweight correlates to pubo-femoral distances and α angles in hip ultrasound of newborns at 6 weeks of age: a retrospective cohort study.

BACKGROUND AND PURPOSE: There is inconsistency in the literature regarding the relationship between increased birthweight and risk of developmental dysplasia of the hip (DDH). We aimed to investigate the correlation between birthweight and pubo-femoral distance (PFD), as well as Graf's α angle in newborns undergoing hip ultrasound examination at 6 weeks of age. PATIENTS AND METHODS: Basic newborn characteristics and ultrasound measurements were retrospectively collected during a 1-year study period. We excluded multiple births, newborns born at less than 37 gestational weeks, and incomplete information. Simple and multiple linear regression analyses were performed to evaluate the correlation of birthweight and PFD, and, second, birthweight and α angles including a stratified regression analysis investigating the potential effect modification of sex. RESULTS: 707 newborns (1,414 hips) were included. Mean birthweight was significantly higher for male newborns (P < 0.001). Increased birthweight was positively correlated to PFD values (crude coefficient 0.21, 95% confidence interval [CI] 0.10-0.32) and the correlation was still present after adjusting for sex, family history, and breech presentation (adjusted coefficient 0.18, CI 0.07-0.29). The stratified α angle model for the males was significant for both the crude coefficient (-0.73, CI -1.28 to -0.19) and the adjusted (-0.59, CI -1.15 to -0.03), and also for the females (crude coefficient -1.14, CI -1.98 to -0.31 and adjusted coefficient -1.15, CI -1.99 to -0.31). CONCLUSION: We found that increased birthweight positively correlated to PFD, and negatively correlated to α angle, but this was not of clinical significance.

A Systematic Review and Meta-Analysis of the Association Between Psychopathology and Social Functioning in Schizophrenia.

BACKGROUND: Impaired social functioning is a major, but under-elucidated area of schizophrenia. It's typically understood as consequential to, eg, negative symptoms, but meta-analyses on the subject have not examined psychopathology in a broader perspective and there's severe heterogeneity in outcome measures. To enhance functional recovery from schizophrenia, a more comprehensive understanding of the nature of social functioning in schizophrenia is needed. STUDY DESIGN: In this systematic review and meta-analysis, we searched PubMed, PsycInfo, and Ovid Embase for studies providing an association between psychopathology and social functioning. Meta-analyses of the regression and correlation coefficients were performed to explore associations between social functioning and psychopathology, as well as associations between their subdomains. STUDY RESULTS: Thirty-six studies with a total of 4742 patients were included. Overall social functioning was associated with overall psychopathology (95% CI [-0.63; -0.37]), positive symptoms (95% CI [-0.39; -0.25]), negative symptoms (95% CI [-0.61; -0.42]), disorganized symptoms (95% CI [-0.54; -0.14]), depressive symptoms (95% CI [-0.33; -0.11]), and general psychopathology (95% CI [-0.60; -0.43]). There was significant heterogeneity in the results, with I2 ranging from 52% to 92%. CONCLUSIONS: This is the first systematic review and meta-analysis to comprehensively examine associations between psychopathology and social functioning. The finding that all psychopathological subdomains seem to correlate with social functioning challenges the view that impaired social functioning in schizophrenia is mainly a result of negative symptoms. In line with classical psychopathological literature on schizophrenia, it may be more appropriate to consider impaired social functioning as a manifestation of the disorder itself.

Psychiatric comorbidity: a concept in need of a theory.

Despite being a relatively new concept, psychiatric comorbidity, i.e. the co-occurrence of two or more mental disorders, has become widespread in clinical practice and psychiatric research. In this article, we trace the origin of the concept of psychiatric comorbidity, discuss the conceptual literature and point to basic problems concerning inadequate definition of the concept, differential diagnostic issues, and reification of mental disorders. We illustrate how these problems may have consequences for diagnostic assessment in current clinical practice and psychiatric research. To address some of the problems related to psychiatric comorbidity, we discuss potential principles for assessing psychiatric comorbidity. Inspired by Feinstein's original concept of comorbidity in general medicine and his differential diagnostic principles, we emphasize the importance of independence of mental disorders when assessing psychiatric comorbidity. We suggest that knowledge of trait v. state conditions and of the multitudinous clinical manifestations beyond what is captured in the diagnostic manuals may be helpful for assessing the independence of mental disorders and thus psychiatric comorbidity. We further argue that a more hierarchical diagnostic system and explicit exclusionary rules could improve clinical practice and research by reducing informational complexity and combating unwarranted psychiatric comorbidity.

MRI May Be More Valuable than Pelvic Radiographs in the Assessment of Paediatric Borderline Acetabular Dysplasia.

The osseous acetabular index (OAI) and cartilaginous acetabular index (CAI) is often used in diagnosing acetabular dysplasia (AD) in children. We examined the reliability of OAI and CAI in AD diagnostics and compared OAI measurements obtained from radiographs versus MRI. Four raters performed retrospective repeated measurements of the OAI and CAI on pelvic radiographs and MRI scans of 16 consecutive patients (mean age 5 years (2-8)) examined for borderline AD during a period of 2½ years. In MRI, the image selected for analysis by the raters was also registered. Spearman's correlation, scatter plots, and Bland-Altman (BA) plots were analysed for correlation between OAI on pelvic radiographs (OAIR) and MRI scans (OAIMRI), while intra- and interrater reliability was assessed for OAIR, OAIMRI, CAI, and MRI image selection using intraclass correlation coefficients (ICC). ICC values for inter- and intrarater reliability of OAIR, OAIMRI, and CAI were all above 0.65, with no significant differences observed. ICC values (CI) for individual raters' MRI image selection was 0.99 (0.998-0.999). The mean difference (95% CI) between OAIR and OAIMRI was -0.99 degrees (-1.84; -0.16), while the mean absolute difference (95% CI) between OAIR and OAIMRI was 3.68 degrees (3.17; 4.20). Absolute differences between OAIR and OAIMRI was independent of pelvic positioning or time interval between radiographs and MRI scans. OAI and CAI had high Intrarater reliability but mediocre interrater reliability. There was an absolute difference of 3.7 degrees in OAI between pelvic radiographs and MRI scans.

Methodological issues in social cognition research in autism spectrum disorder and schizophrenia spectrum disorder: a systematic review.

Recent systematic reviews and meta-analyses conclude that similar social cognitive impairments are found in autism spectrum disorder (ASD) and schizophrenia spectrum disorder (SSD). While methodological issues have been mentioned as a limitation, no study has yet explored the magnitude of methodological heterogeneity across these studies and its potential impact for their conclusion. The purpose of this study was to systematically review studies comparing social cognitive impairments in ASD and SSD with a focus on methodology. Following the PRISMA guidelines, we searched all publications on PubMed, PsycINFO, and Embase. Of the 765 studies identified in our data base searches, 21 cross-sectional studies were included in the review. We found significant methodological heterogeneity across the studies. In the 21 studies, a total of 37 different measures of social cognition were used, 25 of which were only used in 1 study. Across studies, the same measure was often said to be assessing different constructs of social cognition - a confusion that seems to reflect the ambiguous definitions of what these measures test in the studies that introduced them. Moreover, inadequate differential diagnostic assessment of ASD samples was found in 81% of the studies, and sample characteristics were markedly varied. The ASD and SSD groups were also often unmatched in terms of medication usage and substance use disorder history. Future studies must address these methodological issues before a definite conclusion can be drawn about the potential similarity of social cognitive impairments in ASD and SSD.

Late-onset schizophrenia.

Patients with late-onset schizophrenia form a subgroup of schizophrenia that to some extent differs from the typical Gestalt of schizophrenia. Therefore, some of these patients may be overlooked in the clinic. This review describes the characteristics of the late-onset subgroup: Overweight of women, higher education, has been or is still married, and with more children than patients with early onset schizophrenia. The symptomatology of the subgroup is characterised by persecutory delusions and auditory hallucination. Knowledge of this subgroup of patients may lead to attention in the clinic and hopefully have therapeutic value in the recovery process for the patients.

The prognosis of schizophrenia: A systematic review and meta-analysis with meta-regression of 20-year follow-up studies.

OBJECTIVE: The aim was to examine the general outcome of schizophrenia after 20 years or more. METHODS: Using the PRISMA guidelines, we conducted a systematic review and meta-analysis with meta-regression on long-term follow-up studies of schizophrenia up until April 21, 2021. We included prospective studies with at least 20 years of follow-up on patients with a diagnosis of schizophrenia, and the studies had to include face-to-face clinical evaluation. We examined outcome in three nested groups: 'recovery', 'good or better' (including also 'recovery'), and 'moderate or better' (including also 'recovery' and 'good or better'). We used random-effects meta-analysis and meta-regression to examine mean estimates and possible moderators. RESULTS: We identified 1089 records, which were screened by two independent researchers. 14 prospective studies (1991 patients) published between 1978 and 2020 were found eligible. The studies used a range of different scales and definitions for outcome, and some used the same definitions for different outcomes. To compare outcome across studies, we designed and applied a unified template for outcome definitions and cutoffs, based on earlier studies' recommendations. Our meta-analysis found that 24.2 % had 'recovered' (n = 246, CI: 20.3-28.0 %), 35.5 % had a 'good or better' outcome (n = 766, CI: 26.0-45.0%), and 59.7% had 'moderate or better' outcome (n = 1139, CI: 49.3-70.1 %). CONCLUSIONS: The results contribute to debunk the myth that schizophrenia inevitably has a deteriorating course. Recovery is certainly possible. Schizophrenia remains, however, a severe and complex mental disorder, exhibiting a limited change in prognosis despite >100 years of research and efforts to improve treatment.

Pubo-Femoral Distances Measured Reliably by Midwives in Hip Dysplasia Ultrasound.

The pubo-femoral distance (PFD) has been suggested as an ultrasound screening tool for developmental dysplasia of the hip (DDH). The aim of this study was to examine if midwives undergoing minimal training could reliably perform pediatric hip ultrasound and PFD measurements. Eight recruited midwives performed two rounds of independent blinded PFD measurements on 15 static ultrasound images and participated in four supervised live-scanning sessions. The midwives were compared to a group of three experienced musculoskeletal radiologists. Reliability was evaluated using inter-rater correlation coefficients (ICC). Linear regression was used to quantify the learning curve of the midwives as a group. There was near complete intra- and inter-rater agreement (ICC > 0.89) on static ultrasound images across both rounds of rating for midwives and radiologists. The midwives performed a mean of 29 live hip scans (range 24−35). The mean difference between midwives and supervising radiologists was 0.36 mm, 95% CI (0.12−0.61) for the first session, which decreased to 0.20 mm, 95% CI (0.04−0.37) in the fourth session. ICC for PFD measurements increased from 0.59 mm, 95% CI (0.37−0.75) to 0.78 mm, 95% CI (0.66−0.86) with progression in sessions. We conclude that midwives reliably perform PFD measurements of pediatric hips with minimal training.

Exploring tranquility: Eastern and Western perspectives.

Although tranquility is a fundamental aspect of human life, the experiential nature of tranquility remains elusive. Traditionally, many philosophical, religious, spiritual, or mystical traditions in East and West have strived to reach tranquil experiences and produced texts serving as manuals to reach them. Yet, no attempt has been made to compare experiences of tranquility and explore what they may have in common. The purpose of this theoretical study is to explore the experiential nature of tranquility. First, we present examples of what we consider some of the most central experiences of tranquility in Eastern and Western traditions. For the sake of simplicity, we sort these examples into four categories based on their experiential focus: the body, emotions, the mind, and mysticism. Second, we offer an exploratory account of tranquility, arguing that the different examples of tranquility seem to share certain experiential features. More specifically, we propose that the shared features pertain both to the content or quality of the tranquil experiences, which involves a sense of presence and inner peace, and to the structure of these experiences, which seems to involve some degree of detachment and absorption.

Delusional Perception Revisited.

Delusional perception designates a sudden, idiosyncratic, and often self-referential delusion triggered by a neutral perceptual content. In classical psychopathology, delusional perception was considered almost pathognomonic for schizophrenia. Since delusional perception has been erased from ICD-11 and always been absent in DSM, it risks slipping out of clinical awareness. In this article, we explore the clinical roots of delusional perception, elucidate the psychopathological phenomenon, and discuss its two predominant conceptualizations, i.e., Schneider's well-known two-link model and Matussek's lesser known one-link model. The two-link model posits that delusional perception amounts to an abnormal interpretation of an intact perception, whereas the one-link model posits that the delusional meaning is contained within a changed perception. Despite their differences, both models stress that delusional perception is a primary delusion that takes place within an altered experiential framework that is characteristic of the psychopathological Gestalt of schizophrenia. We discuss the role of delusional perception in future psychopathological and diagnostic assessment and argue that such assessments must be conducted in comprehensive manner, eliciting the psychopathological context within which symptoms and signs are embedded. Finally, we discuss the compatibility of the two models of delusional perception with contemporary cognitive models on delusion and cognitive psychotherapeutic approaches.

Self-disorders and psychopathology: a systematic review.

In foundational texts on schizophrenia, the mental disorder was constitutively linked to a specific disintegration of subjectivity (often termed a self-disorder). Apart from Scharfetter's work on ego-pathology, research on self-disorders generally faded into oblivion, and self-disorders were only rediscovered as notable psychopathological features of the schizophrenia spectrum nearly two decades ago. Subsequently, the Examination of Anomalous Self-Experience (EASE) scale was constructed to allow systematic assessment of non-psychotic self-disorders. This Review is the first systematic review of empirical studies on self-disorders based on the EASE or other related scales. The results consistently show that self-disorders hyper-aggregate in schizophrenia spectrum disorders but not in other mental disorders; that self-disorders are found in individuals at a clinical risk of developing psychosis; that self-disorders show a high degree of temporal stability; that self-disorders predict the later development of schizophrenia spectrum disorders; and that self-disorders correlate with the canonical dimensions of the psychopathology of schizophrenia, impaired social functioning, and suicidality. Issues with the methods of the reviewed literature are critically discussed and the role of self-disorders in clinical psychiatry and future research is outlined.

"Transition" to Schizophrenia or Fluctuations within the Same Disorder?

BACKGROUND: To prevent or delay the onset of psychotic disorders or ameliorate their course, prodromal research has strived to identify and treat individuals at risk of developing psychosis. While this approach is laudable, it is, however, not entirely unproblematic from clinical and conceptual perspectives. For example, it remains unclear how we are to understand the development from a nonpsychotic, distressing condition such as schizotypal disorder to a psychotic disorder such as schizophrenia? The current terminology on the subject implies either a nonlinear jump ("conversion") or a more linear progression ("transition") from one disorder to another. To enrich our understanding of such diagnostic shifts, we examined the psychopathological pictures of patients who "transitioned" from schizotypal disorder to schizophrenia. METHODS: From a larger study on psychopathology, we examined 40 patients who were diagnosed with schizotypal disorder at baseline. At 5-year follow-up, 30 patients maintained the diagnosis of schizotypal disorder, while 10 were re-diagnosed with schizophrenia. We examined detailed descriptions of the 10 patients who progressed to schizophrenia, comparing psychopathology and level of functioning. RESULTS: The level of functioning decreased slightly from baseline to follow-up in 9 out of 10 patients. Eight patients had previously had micro-psychotic or psychotic experiences. All patients had self-disorders at baseline, and several patients had perceptual disorders. Nine patients had formal thought disorders at baseline. The progression is illustrated by 2 cases. CONCLUSION: In this small study, we did not find any striking changes in any of the patients, neither in terms of psychopathological manifestations nor in terms of their level of functioning. Thus, rather than witnessing a genuine "conversion" or "transition" from schizotypal disorder to schizophrenia, we observed dimensional fluctuations within the same condition.

Disordered Selfhood in Schizophrenia and the Examination of Anomalous Self-Experience: Accumulated Evidence and Experience.

Disordered selfhood in schizophrenia was rediscovered at the turn of the millennium. In 2005, Psychopathology published the psychometric instrument, the Examination of Anomalous Self-Experience (EASE). In this article, we summarize the historical background of the creation of the EASE, explicate the notion of the disorder of basic or minimal self with the help of phenomenological philosophy, and provide a brief description of clinical manifestations targeted by the EASE. We also present our personal experience using and teaching the EASE and summarize the empirical evidence obtained so far. We conclude that the basic self-disorder represents a crucial phenotype of schizophrenia spectrum disorders and that this phenotype offers a potential avenue to empirical pathogenetic research and psychotherapeutic treatment.

Changes in clinical and social situation after involuntary admission of homeless people with psychotic disorders: a one-year follow-up study.

BACKGROUND: Mental illness is one of the main reasons for homelessness in Denmark. Yet, some patients do not accept psychiatric treatment despite need for treatment. This can lead to involuntary admission. In this study, we examined changes after involuntary admissions of mentally ill homeless people. METHODS: We conducted a longitudinal, naturalistic follow-up study of patients who had been involuntarily admitted by the Homeless Outreach Psychiatric Service through 1 year. We examined changes in mental condition, social situation, and substance use of mentally ill homeless people one year after involuntary admission. RESULTS: At baseline, 28 patients were included: 86% of them had been admitted before, 46% had a substance use, and 25% had prior been convicted of a violent crime. 89% of the patients were discharged to the streets. At 12 months, 50% of the patients had symptom reduction, 36% were in psychiatric treatment, and only 14% had acquired permanent housing. No improvements in substance use were observed and 11% of the patients had new convictions after 12 months. During the study period, a total of 24 readmissions distributed on 14 patients was found. CONCLUSION: Involuntary admissions can be an effective treatment of psychiatric aspects of mentally ill homeless patients. Unfortunately, a substantial part of these patients was quickly discharged before sufficient treatment, leaving room for improvement. Furthermore, few improvements were seen concerning the patients' social situation. More focus on the coherence between psychiatric and municipality services, targeting the social issues and substance use of homeless patients, is strongly needed.

What is the association between MRI and conventional radiography in measuring femoral head migration?

Background and purpose - Pelvic radiographs are traditionally used for assessing femoral head migration in residual acetabular dysplasia (RAD). Knowledge of the heightened importance of cartilaginous structures in this condition has led to increased use of MRI in assessing both osseous and cartilaginous structures of the pediatric hip. Therefore, we assessed the relationship between migration percentages (MP) found on MRI and conventional radiographs. Second, we analyzed the reliability of MP in MRI and radiographs.Patients and methods - We retrospectively identified 16 patients (mean age 5 years [2-8], 14 girls), examined for RAD during a period of 2½ years. 4 raters performed blinded repeated measurements of osseous migration percentage (MP) and cartilaginous migration percentage (CMP) in MRI and radiographs. Pelvic rotation and tilt indices were measured in radiographs. Bland-Altman (B-A) plots and intraclass correlation coefficients (ICC) were calculated for agreement and reliability.Results - B-A plots for MPR and MPMRI produced a mean difference of 6.4 with limits of agreement -11 to 24, with higher disagreements at low average MP values. Mean MPR differed from mean MPMRI (17% versus 23%, p < 0.001). MPR had the best interrater reliability with an ICC of 0.92 (0.86-0.96), compared with MPMRI and CMP with ICC values of 0.61 (0.45-0.70) and 0.52 (0.26-0.69), respectively. Intrarater reliability for MPR, MPMRI and CMP all had ICC values above 0.75 and did not differ statistically significantly. Differences inMPMRI and MPR showed no correlation to pelvic rotation index, pelvic tilt index, or interval between radiograph and MRI exams.Interpretation - Pelvic radiographs underestimated MP when compared with pelvic MRI. We propose CMP as a new imaging measurement, and conclude that it has good intrarater reliability but moderate interrater reliability. Measurement of MP in radiographs and MRI had mediocre to excellent reliability.
