Implementing proposed reforms of the Mental Health Act for people with intellectual disability and autism: the perspective of multidisciplinary professionals in intellectual disability teams.

BACKGROUND: A recent government white paper sets out proposals for reforms to the Mental Health Act 1983 (MHA). Some of these proposals affect people with intellectual disabilities and/or autism. AIMS: To explore both positive and unintended negative effects of the proposed reforms by gathering the perspectives of healthcare workers from multiple disciplines, working with intellectual disability and/or autism in community and in-patient settings. METHOD: A 14-question electronic questionnaire, comprising free-text, multiple choice and five-point Likert scale responses, was sent out via email between April and July 2021, to all multidisciplinary team professionals working in specialist intellectual disability community and in-patient teams in Hertfordshire Partnership University NHS Foundation Trust. RESULTS: There were 45 responders, of whom 53% worked in in-patient settings and 47% in out-patient teams. Respondents comprised healthcare professionals from multiple disciplines, 80% of which were non-medical. Most responders agreed with the general principles of the proposed reforms. However, 80% felt there would be potentially unintended consequences, and 76% thought that substantial investment in community services was required in advance of the proposed reforms. CONCLUSIONS: The proposed MHA reforms may have unintended consequences for people with intellectual disabilities and/or autism. The findings of this study raised key concerns that need to be explored further and addressed before the MHA reforms are implemented. These include community provision, safeguards and use of the Mental Capacity Act, the potential for under or overdiagnosis of mental illness, and effects associated with the criminal justice system.

Plasma glial fibrillary acidic protein and neurofilament light chain, but not tau, are biomarkers of sports-related mild traumatic brain injury.

Mild traumatic brain injury is a relatively common event in contact sports and there is increasing interest in the long-term neurocognitive effects. The diagnosis largely relies on symptom reporting and there is a need for objective tools to aid diagnosis and prognosis. There are recent reports that blood biomarkers could potentially help triage patients with suspected injury and normal CT findings. We have measured plasma concentrations of glial and neuronal proteins and explored their potential in the assessment of mild traumatic brain injury in contact sport. We recruited a prospective cohort of active male rugby players, who had pre-season baseline plasma sampling. From this prospective cohort, we recruited 25 players diagnosed with mild traumatic brain injury. We sampled post-match rugby players without head injuries as post-match controls. We measured plasma neurofilament light chain, tau and glial fibrillary acidic protein levels using ultrasensitive single molecule array technology. The data were analysed at the group and individual player level. Plasma glial fibrillary acidic protein concentration was significantly increased 1-h post-injury in mild traumatic brain injury cases compared to the non-injured group (P = 0.017). Pairwise comparison also showed that glial fibrillary acidic protein levels were higher in players after a head injury in comparison to their pre-season levels at both 1-h and 3- to 10-day post-injury time points (P = 0.039 and 0.040, respectively). There was also an increase in neurofilament light chain concentration in brain injury cases compared to the pre-season levels within the same individual at both time points (P = 0.023 and 0.002, respectively). Tau was elevated in both the non-injured control group and the 1-h post-injury group compared to pre-season levels (P = 0.007 and 0.015, respectively). Furthermore, receiver operating characteristic analysis showed that glial fibrillary acidic protein and neurofilament light chain can separate head injury cases from control players. The highest diagnostic power was detected when biomarkers were combined in differentiating 1-h post-match control players from 1-h post-head injury players (area under curve 0.90, 95% confidence interval 0.79-1.00, P < 0.0002). The brain astrocytic marker glial fibrillary acidic protein is elevated in blood 1 h after mild traumatic brain injury and in combination with neurofilament light chain displayed the potential as a reliable biomarker for brain injury evaluation. Plasma total tau is elevated following competitive rugby with and without a head injury, perhaps related to peripheral nerve trauma and therefore total tau does not appear to be suitable as a blood biomarker.

Pyroptosis in Liver Disease: New Insights into Disease Mechanisms.

There has been increasing interest in pyroptosis as a novel form of pro-inflammatory programmed cell death. The mechanism of pyroptosis is significantly different from other forms of cell death in its morphological and biochemical features. Pyroptosis is characterized by the activation of two different types of caspase enzymes-caspase-1 and caspase-4/5/11, and by the occurrence of a proinflammatory cytokine cascade and an immune response. Pyroptosis participates in the immune defense mechanisms against intracellular bacterial infections. On the other hand, excessive inflammasome activation can induce sterile inflammation and eventually cause some diseases, such as acute or chronic hepatitis and liver fibrosis. The mechanism and biological significance of this novel form of cell death in different liver diseases will be evaluated in this review. Specifically, we will focus on the role of pyroptosis in alcoholic and non-alcoholic fatty liver disease, as well as in liver failure. Finally, the therapeutic implications of pyroptosis in liver diseases will be discussed.

Long-term outcomes of patients with hepatitis B virus-related acute on chronic liver failure: An observational cohort study.

BACKGROUND AND AIMS: The long-term outcomes of patients with hepatitis B virus-related acute on chronic liver failure (HBV-ACLF) remain unclear. The main aim of the study was to compare the 5-year survival rate and incidence rate of hepatocellular carcinoma (HCC) between patients with HBV-ACLF and HBV-cirrhosis. METHODS: Clinical data of patients with ACLF, compensated cirrhosis and decompensated cirrhosis who survived more than 3 months after diagnosis were collected. The survival rate and cumulative incidence of HCC were compared. The Cox regression was used to evaluate risk factors for outcomes. RESULTS: A total of 814 patients were included in the analysis, including 122 (14.99%) patients with ACLF, 450 (55.28%) patients with compensated cirrhosis and 242 (29.73%) patients with decompensated cirrhosis. The 5-year survival rate of patients with ACLF (97.2%) was higher than patients with decompensated cirrhosis (86.0%), but was lower than patients with compensated cirrhosis (99.1%). The 5-year HCC incidence rate was the highest in the decompensated cirrhosis group (14.6%, P < 0.05), while no statistical differences were found between patients with ACLF (3.5%) and compensated cirrhosis (9.5%). The episode of ACLF did not increase the risk of HCC and the overall survival when compared with patients with cirrhosis. In ACLF subgroup analysis, the age, rather than the presence of cirrhosis, was independently associated with both mortality and incidence of HCC. CONCLUSIONS: ACLF patients who survived the first 3 months had a better long-term prognosis than decompensated cirrhosis, while the HCC risk was comparable to compensated cirrhosis. HCC surveillance is strongly recommended for these patients.

Is Toxoplasma gondii infection correlated with nonalcoholic fatty liver disease?- a population-based study.

BACKGROUND: Previous studies have suggested that Toxoplasma gondii (T. gondii) infection might be associated with fatty liver disease. However, the relationship between non-alcoholic fatty liver disease (NAFLD) and T. gondii infection has not been investigated in a large population. We aimed to study the relationship between those two diseases using a population-based dataset from the United States. METHODS: The data were collected from the third National Health and Nutrition Examination Survey (NHANES III) between 1988 and 1994. Statistical analysis was applied to compare the prevalence of NAFLD in anti-T. gondii antibody-positive participants with antibody-negative ones. RESULTS: A total of 9465 persons with a mean age of 44.33 ± 16.21 years, 46.9% of which were males, were included in the final analysis. Their mean BMI was 27.60 ± 5.96 kg/m2. A total of 2520 participants (26.62%) were positive for the T. gondii antibody. There was an increasing trend of seroprevalence of T. gondii with age (P for trend < 0.001). The incidence of NAFLD in the seropositive group was higher than that in the seronegative group (27.10% vs 23.40%, p < 0.001). In addition to this, metabolic biomarkers, including serum lipid, fasting blood-glucose, and uric acid were also significantly higher in the seropositive group. However, multivariate analysis revealed that T. gondii infection was not an independent risk factor for NAFLD. Age was independently correlated with both the prevalence of T. gondii and NAFLD. CONCLUSIONS: Patients with T. gondii infection may have a higher prevalence of NAFLD. Age may have an effect on the increase of NAFLD in the T. gondii seropositive population.
