Early-Onset Schizophrenia: Exploring the Contribution of the Thought Disorder Index to Clinical Assessment

Background: Differentiating diagnostically between schizophrenia and emotional and personality disorders with psychotic or psychotic-like symptoms is a challenging task. It is especially difficult when working with adolescent patients, because their symptoms tend to manifest at lower levels as compared with adult patients. Thought disorder is a core symptom of schizophrenia, and the Rorschach Inkblot Method is widely used for the assessment of formal thought disorder. Objective: In this study, which is situated within ongoing clinical practice, we investigated whether the Rorschach test is helpful for assessing early-onset schizophrenia due to its ability to detect thought disorder. We also wanted to examine whether the Thought Disorder Index (TDI) is superior to the Comprehensive System (CS) for differentiating between patients with early-onset schizophrenia and non-psychotic patients experiencing auditory and visual hallucinations. An additional aim was to examine whether the TDI correlated with the Positive and Negative Syndrome Scale (PANSS). Methods: Twenty-three subjects between the ages of 12 and 18 years were examined with the use of the Rorschach test, and the protocols were scored according to both the TDI and the CS. All subjects were also assessed with the Positive and Negative Syndrome Scale. The sample included 14 subjects who fulfilled the criteria for schizophrenia and 9 subjects who were experiencing hallucinations that emanated from severe emotional and relational problems but who had different non-psychotic disorders. Results: Although the two groups could not be distinguished with regard to their total scores for thought disorder, the identification of specific thought disorder types proved useful for differential diagnosis. Verbalizations that were categorized by the TDI as “absurd responses,” “fluidity,” “contamination,” “autistic logic,” and “word-finding difficulty” were only given by patients who had been diagnosed with schizophrenia. When patients’ responses were scored with the use of the CS, the “contamination” score was the only one found to be specific to schizophrenia. Conclusions: Although the sample size limits the conclusions that can be drawn, the results indicate that the TDI may be superior to the CS for the identification of thought disorder specific to—but not always present in—adolescents with schizophrenia. In other words, the absence of severe thought disorder is not synonymous with the absence of severe psychopathology, but the presence of the most severe thought disorder types (i.e., “absurd responses,” “fluidity,” “incoherence,” “contamination,” and “autistic logic”) seems to be a strong indicator of schizophrenic psychopathology

Efficacy of FODMAP Elimination and Subsequent Blinded Placebo-Controlled Provocations in a Randomised Controlled Study in Patients with Ulcerative Colitis in Remission and Symptoms of Irritable Bowel Syndrome:A Feasibility Study

Background: Patients with inflammatory bowel disease (IBD) and symptoms of irritable bowel syndrome (IBS) may be intolerant to fermentable carbohydrates (FODMAPs). The aim of this study was to test the feasibility of eliminating and subsequently reintroducing FODMAPs in patients with IBS symptoms as part of the IBD manifestation and to compare the severity of IBS symptoms and pain, bloating and quality of life (QoL). Methods: An eight-week randomised open-label FODMAP elimination with double-blinded, crossover provocations of FODMAP and placebo. Diet patients were on a low-FODMAP diet for eight weeks with blinded two-week provocations after two and six weeks. Questionnaires, blood and stool samples were collected. Results: Patient enrolment was challenging. Nineteen participants were included in the study. Eliminating low FODMAP for two weeks resulted in significant decreases in pain and bloating scores (p 0.05). Conclusions: The results document the possibility of performing a randomised controlled study following the gold standard for testing food intolerance with blinding of the Low FODMAP diet. Recruitment of participants was challenging

Undervisningsdifferentiering i dansk og matematik i 5. klasse – med fokus på elever med særlige behov: Vol. 1

En af de mest markante udfordringer, som lærere møder i deres respektive klasser, er en øget mangfoldighed i elevgruppen, hvad angår måder at lære på. Det stiller lærerne over for store udfordringer i forhold til at differentiere undervisningen, hvad angår skolens og klasserummets fysiske rammer, sociale organiseringer, fagligt indhold, undervisningsmaterialernes art og sværhedsgrader, arbejdsformer, tempo etc. Lærerne kan således differentiere i forhold til, hvad eleven skal lære, dvs. indholdet, hvordan eleven skal lære, dvs. processen, eller resultatet, dvs. hvad eleven giver udtryk for at have lært.Projektet ’Undervisningsdifferentiering med fokus på elever med særlige behov’ er gennemført i håbet om at kunne inspirere lærere og lærerstuderende til at udvikle skolens praksis i en mere undervisningsdifferentieret retning. Derfor er der lagt vægt på en webbaseret formidling af resultater og erfaringer fra projektet, som skolens aktører og andre interesserede let kan få adgang til via en temahjemmeside på www.Inklusionsudvikling.d

SARS-CoV-2 antibody prevalence among homeless people and shelter workers in Denmark:a nationwide cross-sectional study

BACKGROUND: People experiencing homelessness (PEH) and associated shelter workers may be at higher risk of infection with “Severe acute respiratory syndrome coronavirus 2” (SARS-CoV-2). The aim of this study was to determine the prevalence of SARS-CoV-2 among PEH and shelter workers in Denmark. DESIGN AND METHODS: In November 2020, we conducted a nationwide cross-sectional seroprevalence study among PEH and shelter workers at 21 recruitment sites in Denmark. The assessment included a point-of-care test for antibodies against SARS-CoV-2, followed by a questionnaire. The seroprevalence was compared to that of geographically matched blood donors considered as a proxy for the background population, tested using a total Ig ELISA assay. RESULTS: We included 827 participants in the study, of whom 819 provided their SARS-CoV-2 antibody results. Of those, 628 were PEH (median age 50.8 (IQR 40.9–59.1) years, 35.5% female) and 191 were shelter workers (median age 46.6 (IQR 36.1–55.0) years and 74.5% female). The overall seroprevalence was 6.7% and was similar among PEH and shelter workers (6.8% vs 6.3%, p = 0.87); and 12.2% among all participants who engaged in sex work. The overall participant seroprevalence was significantly higher than that of the background population (2.9%, p < 0.001). When combining all participants who reported sex work or were recruited at designated safe havens, we found a significantly increased risk of seropositivity compared to other participants (OR 2.23, 95%CI 1.06–4.43, p = 0.02). Seropositive and seronegative participants reported a similar presence of at least one SARS-CoV-2 associated symptom (49% and 54%, respectively). INTERPRETATIONS: The prevalence of SARS-CoV-2 antibodies was more than twice as high among PEH and associated shelter workers, compared to the background population. These results could be taken into consideration when deciding in which phase PEH are eligible for a vaccine, as part of the Danish national SARS-CoV-2 vaccination program rollout.

A Case Study on the Behavioural Effect of Positive Reinforcement Training in a Novel Task Participation Test in Göttingen Mini Pigs

In laboratory animal research, many procedures will be stressful for the animals, as they are forced to participate. Training animals to cooperate using clicker training (CT) or luring (LU) may reduce stress levels, and thereby increase animal welfare. In zoo animals, aquarium animals, and pets, CT is used to train animals to cooperate during medical procedures, whereas in experimental research, LU seem to be the preferred training method. This descriptive case study aims to present the behaviour of CT and LU pigs in a potentially fear-evoking behavioural test—the novel task participation test—in which the pigs walked a short runway on a novel walking surface. All eight pigs voluntarily participated, and only one LU pig showed body stretching combined with lack of tail wagging indicating reduced welfare. All CT pigs and one LU pig displayed tail wagging during the test, indicating a positive mental state. Hence, training pigs to cooperate during experimental procedures resulted in a smooth completion of the task with no signs of fear or anxiety in seven out of eight animals. We suggest that training laboratory pigs prior to experimental procedures or tests should be done to ensure low stress levels

Prevalence of the use of antihypertensive medications in Greenland: a study of quality of care amongst patients treated with antihypertensive drugs

Objectives. The primary objective was to estimate the prevalence of patients diagnosed with hypertension using the proxy marker of antihypertensive drug therapy in Greenland and to compare the prevalences within the 5 health regions in Greenland. The second objective was to review 2 quality indicators in antihypertensive care. Study design. Observational and cross-sectional study reviewing electronic medical records. Methods. Information about age and gender was collected from all patients receiving antihypertensive drug prescriptions within a 2-year period prior to the data extraction in January 2011. Only patients aged 20 or above were included. The age- and gender-specific prevalence of patients in antihypertensive treatment was calculated using the population as it was 1 January 2010 in Greenland as background population. A subsample consisting of patients in antihypertensive treatment aged 20 or above born within the first 5 days of each month was identified. Review of electronic medical records 1 year back in time (1 January 2010 onwards) was carried out and information on blood pressure obtained. The quality of care was evaluated with respect to 2 indicators: follow-up management and blood pressure level, respectively. Results. The total number of patients in treatment with antihypertensive drugs was 4,462 (1,998 males and 2,464 females) corresponding to a prevalence of 11.4% (4,462/39,231). The prevalence was higher among females than among males. The prevalence increased with age and differed among the 5 health regions. The percentage of patients in antihypertensive treatment with minimum 1 follow-up visit within 1 year (blood pressure measured and registered in a health clinic) was only 77.7%. Some 45% of patients in antihypertensive treatment achieved blood pressure below 140/90 mmHg. Conclusion. Hypertension is a common disorder in Greenland. The quality of antihypertensive care is suboptimal and leaves room for improvement. A national strategy based on guidelines, use of electronic drug prescriptions and recording of blood pressures combined with continuous monitoring the quality is recommended in order to prevent complications of untreated hypertension
