An estimated 170 million people worldwide have hepatitis C, which is a significant cause of morbidity and mortality. Therefore, health professionals (HPs) are likely to care for people with hepatitis C at some stage in their careers. However, little is known about HPs' attitudes towards treating people with hepatitis C. An analytical, cross-sectional survey was conducted to explore the inter-relationship among HPs' hepatitis C knowledge and attitudes towards treating people with hepatitis C and their self-reported clinical behaviour: Self-administered questionnaires were distributed to 3675 complementary therapists, dentists, medical practitioners, nurses, pharmacists, undergraduate medical and nursing students and people with hepatitis C in Victoria, Australia. Forty-six per cent responded (n = 1510). Only HP (complementary therapists, dentists, medical practitioners, nurses and pharmacists) data is presented (n = 1347). Most HPs demonstrated adequate hepatitis C knowledge, but some displayed intolerant attitudes toward people with hepatitis C. Their self-reported compliance with infection control practices indicated that they frequently treated people with hepatitis C differently from other patients by using additional infection control precautions while treating patients with hepatitis C. In addition, fear of contagion and disapproval of injecting drug use emerged as barriers to their willingness to treat people with hepatitis C. The results suggest that focusing education strategies on changing HPs' attitudes toward people with hepatitis C, injecting drug users, and infection control guidelines rather than concentrating solely on medical information might ultimately improve patient care.

Epidemiological studies have established that heavy alcohol consumption in persons with chronic hepatitis C virus (HCV) infection is associated with advanced liver disease, including cirrhosis. The aims of this study were to evaluate the relationship between alcohol consumption and hepatocyte apoptosis in HCV-infected patients and to determine the role of Fas in HCV-mediated apoptosis. Liver tissue from 44 HCV-infected patients with variable alcohol consumption, and 10 normal control subjects who did not consume alcohol was examined for hepatocyte apoptosis, proliferation and Fas expression. Alcohol consumption was assessed using the 'Lifetime Drinking History' alcohol questionnaire. HCV RNA, alanine aminotransferase (ALT) and ferritin were also assessed in addition to demographic data. Hepatocyte apoptosis was significantly greater in HCV-infected patients compared to controls. Expression of Fas (CD95) was found in HCV patients but not in controls. The degree of Fas expression correlated with hepatocyte apoptosis as detected by terminal UTP nick end labelling (TUNEL). Active ethanol consumption led to a significant increase in hepatocyte apoptosis. Fas expression correlated with fibrosis in HCV-infected patients who were not actively drinking ethanol. In summary, HCV leads to increased apoptotic cell death in hepatocytes. Programmed cell death can be further up-regulated by active ethanol consumption. The correlation between Fas expression and TUNEL supports the hypothesis that the Fas-Fas ligand interaction is the major mechanism for HCV-induced hepatocyte apoptosis.

ImportanceBrain-computer interface (BCI) implants have previously required craniotomy to deliver penetrating or surface electrodes to the brain. Whether a minimally invasive endovascular technique to deliver recording electrodes through the jugular vein to superior sagittal sinus is safe and feasible is unknown.ObjectiveTo assess the safety of an endovascular BCI and feasibility of using the system to control a computer by thought.Design, Setting, and ParticipantsThe Stentrode With Thought-Controlled Digital Switch (SWITCH) study, a single-center, prospective, first in-human study, evaluated 5 patients with severe bilateral upper-limb paralysis, with a follow-up of 12 months. From a referred sample, 4 patients with amyotrophic lateral sclerosis and 1 with primary lateral sclerosis met inclusion criteria and were enrolled in the study. Surgical procedures and follow-up visits were performed at the Royal Melbourne Hospital, Parkville, Australia. Training sessions were performed at patients’ homes and at a university clinic. The study start date was May 27, 2019, and final follow-up was completed January 9, 2022.InterventionsRecording devices were delivered via catheter and connected to subcutaneous electronic units. Devices communicated wirelessly to an external device for personal computer control.Main Outcomes and MeasuresThe primary safety end point was device-related serious adverse events resulting in death or permanent increased disability. Secondary end points were blood vessel occlusion and device migration. Exploratory end points were signal fidelity and stability over 12 months, number of distinct commands created by neuronal activity, and use of system for digital device control.ResultsOf 4 patients included in analyses, all were male, and the mean (SD) age was 61 (17) years. Patients with preserved motor cortex activity and suitable venous anatomy were implanted. Each completed 12-month follow-up with no serious adverse events and no vessel occlusion or device migration. Mean (SD) signal bandwidth was 233 (16) Hz and was stable throughout study in all 4 patients (SD range across all sessions, 7-32 Hz). At least 5 attempted movement types were decoded offline, and each patient successfully controlled a computer with the BCI.Conclusions and RelevanceEndovascular access to the sensorimotor cortex is an alternative to placing BCI electrodes in or on the dura by open-brain surgery. These final safety and feasibility data from the first in-human SWITCH study indicate that it is possible to record neural signals from a blood vessel. The favorable safety profile could promote wider and more rapid translation of BCI to people with paralysis.Trial RegistrationClinicalTrials.gov Identifier: NCT03834857

SUMMARY BackgroundInflammatory bowel disease can impact on a patient's ability to maintain normal physical and mental function, and fulfil their social, family and work roles. Aspects of disability in IBD have received little attention.
