COVID-19-related stigma and its influencing factors: a nationwide cross-sectional study during the early stage of the pandemic in China

Objectives To describe the situation of COVID-19-related stigma towards patients with COVID-19 and people from the city of Wuhan in China and to assess the associations between COVID-19-related stigma, health literacy and sociodemographic characteristics during March 2020, the early stage of the pandemic. Design A cross-sectional online survey. Setting The study surveyed 31 provinces in China. Participants This study surveyed 5039 respondents in China. Outcome measures Public stigma towards both patients with COVID-19 and Wuhan residents was measured. Binary logistic regression was used to identify the factors associated with public COVID-19-related stigma. Results Among the participants, 122 (2.4%) reported themselves and 254 (5.0%) reported the communities they lived in as holding a stigmatising attitude towards patients with COVID-19, respectively. Additionally, 114 (2.5%) and 475 (10.3%) reported that themselves and the communities they lived in, respectively, held a stigma against people from Wuhan, which was the most severely affected area in China. People aged over 40, lived in areas with severe epidemics (adjusted OR (aOR)=2.03, 95% CI (1.05 to 3.92)) and who felt it difficult to find and understand information about COVID-19 (aOR=1.91, 95% CI (1.08 to 3.37); aOR=1.88, 95% CI (1.08 to 3.29)) were more likely to stigmatise patients with COVID-19. People who were male, aged 41–50 and had difficulty understanding information (aOR=2.08, 95% CI (1.17 to 3.69)) were more likely to stigmatise people from Wuhan. Conclusions Patients with COVID-19 and Wuhan residents suffered stigma at both the individual and the community levels. Those who had low health literacy, who lived in areas with a large number of COVID-19 cases and who were of ethnic minorities were more likely to stigmatise others. Tailored interventions are encouraged to improve health literacy and consequently to reduce public COVID-19-related stigma.
Predicted Risks of Cardiovascular Disease Following Chemotherapy and Radiotherapy in the UK NCRI RAPID Trial of Positron Emission Tomography–Directed Therapy for Early-Stage Hodgkin Lymphoma

PURPOSE The contemporary management of early-stage Hodgkin lymphoma (ES-HL) involves balancing the risk of late adverse effects of radiotherapy against the increased risk of relapse if radiotherapy is omitted. This study provides information on the risk of radiation-related cardiovascular disease to help personalize the delivery of radiotherapy in ES-HL. METHODS We predicted 30-year absolute cardiovascular risk from chemotherapy and involved field radiotherapy in patients who were positron emission tomography (PET)–negative following three cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy within a UK randomized trial of PET-directed therapy for ES-HL. Cardiac and carotid radiation doses and chemotherapy exposure were combined with established dose-response relationships and population-based mortality and incidence rates. RESULTS Average mean heart dose was 4.0 Gy (range 0.1-24.0 Gy) and average bilateral common carotid artery dose was 21.5 Gy (range 0.6-38.1 Gy), based on individualized cardiovascular dosimetry for 144 PET-negative patients receiving involved field radiotherapy. The average predicted 30-year radiation-related absolute excess overall cardiovascular mortality was 0.56% (range 0.01%-6.79%; < 0.5% in 67% of patients and > 1% in 15%), whereas average predicted 30-year excess incidence was 6.24% (range 0.31%-31.09%; < 5% in 58% of patients and > 10% in 24%). For cardiac disease, the average predicted 30-year radiation-related absolute excess mortality was 0.42% (0.79% with mediastinal involvement and 0.05% without) and for stroke, it was 0.14%. CONCLUSION Predicted excess cardiovascular risk is small for most patients, so radiotherapy may provide net benefit. However, for a minority of patients receiving high doses of radiation to cardiovascular structures, it may be preferable to consider advanced radiotherapy techniques to reduce doses or to omit radiotherapy and accept the increased relapse risk. Individual assessment of cardiovascular and other risks before treatment would allow personalized decision making about radiotherapy in ES-HL. Cardiovascular risk of RT in PET-negative early stage Hodgkin lymphoma very small for most patients
Risk of Hospitalization and Death Associated With Pimavanserin Use in Older Adults With Parkinson Disease

Background and Objectives To determine the risk of hospitalization and death associated with pimavanserin use. Methods We conducted a retrospective cohort study of adults 65 years and older with Parkinson disease between November 1, 2015, and December 31, 2018, using an administrative dataset on residents of Medicare-certified long-term care facilities and linked Medicare claims data. Propensity score–based inverse probability of treatment weighting (IPTW) was used to balance pimavanserin users and nonusers on 24 baseline characteristics. Fine-Gray competing risk and Cox proportional hazards regression models were used to estimate the risk of hospitalization and death up to 1 year, respectively. Results The study cohort included 2,186 pimavanserin users and 18,212 nonusers. There was a higher risk of 30-day hospitalization with pimavanserin use vs nonuse (IPTW-adjusted hazard ratio [aHR] 1.24, 95% confidence intervals [CI] 1.06–1.43). There was no association of pimavanserin use with 90-day hospitalization (aHR 1.10, CI 0.99–1.24) or with 30-day mortality (aHR 0.76, CI 0.56–1.03). Pimavanserin use vs nonuse was associated with increased 90-day mortality (aHR 1.20, CI 1.02–1.41) that persisted after 180 days (aHR 1.28, CI 1.13–1.45) and 1 year (aHR 1.56, CI 1.42–1.72). Discussion Pimavanserin use vs nonuse in older adults was associated with an increased risk of hospitalization at 1 month of initiation and a higher risk of death for up to 1 year following initiation. These findings, in a large real-world cohort within long-term care facilities, may help to inform decisions regarding its risk/benefit balance among patients with Parkinson disease. Classification of Evidence This study provides Class II evidence that in patients with Parkinson disease who are 65 or older and residing in Medicare-certified long-term care facilities, pimavanserin is associated with an increased risk of 30-day hospitalization and higher 90-, 180-, and 365-day mortality.
Effect of magnetic field on tribological performances of two lubricating oils with phosphorus‐containing additives

The influence of magnetic field on the tribological properties of 150SN mineral oil and the oils formulated with tricresyl phosphate or ammonium thiophosphate was evaluated on a modified 4‐ball tribo‐tester. The influencing mechanisms were discussed from the viewpoint of physical effect and chemical effect. The results indicated that the applied magnetic field improved the anti‐wear ability of the neat mineral oil and T306‐doped oils but impaired that of T307‐doped oils. The friction‐reducing capacity of the tested oils was undermined by the magnetic field. The atomic concentrations of the functional elements identified in T306 or T307 under magnetic field were higher or lower than those without magnetic impact, respectively. The magnetic force between steel balls and tribo‐diffusion of the functional elements contained in T306 or T307 into the substrate induced by magnetism was inferred to impair the friction‐reducing performances of the formulated oils.
Does face mask use elicit risk-compensation? Quasi-experimental evidence from Denmark during the SARS-CoV-2 pandemic.

BACKGROUND Public use of face masks has been widely adopted to halter the SARS-CoV-2 pandemic, but a key concern has been whether the effectiveness of face mask use is limited due to the elicitation of false feelings of security that decrease the observance of other protective behaviors, the so-called risk-compensation. METHODS We exploit quasi-experimental variation, prompted by three major changes in policy, to assess whether public use of face masks elicit risk-compensation by increasing the number of close contacts or decreasing attention to distancing and hygiene measured in daily nationally representative surveys (N = 106 880). RESULTS Number of close contacts: face mask use prompted by the policy changes decrease the number of contacts in two of the three interventions. In the remaining intervention, it has no effect. Attention to hygiene: across the changes, face masks use does not affect people's attention to hygiene. Attention to distancing: in two of three interventions, face mask use increase attention to distancing. In the remaining intervention, we see a decrease in attention. CONCLUSIONS Overall, public use of face masks may occasionally elicit a narrow form of risk-compensation; specifically, reducing engagement in physical distancing. However, such narrow forms of risk-compensation are limited: the results do not reveal any effects on the actual number of physical contacts, only on the psychological attention to distancing advice. Moreover, the negative effect only appears for one of three interventions. The other two interventions suggest that face mask use increases attention to physical distancing.
Ultrahigh field in vivo characterization of microstructural abnormalities in the orbitofrontal cortex and amygdala in autism

There are currently no biomarkers for autism spectrum disorder (ASD). This neurodevelopmental condition has previously been associated with histopathological findings, including increased neuronal packing density in the amygdala, abnormal laminar cytoarchitecture and increased average neuronal density in the prefrontal cortex. The present study examined whether new brain imaging technologies could reveal in vivo, in adults with ASD, the manifestation of previously described histopathological changes. Using quantitative mapping at ultrahigh field (7 Tesla), we show that we can observe microstructural alterations in the right lateral orbitofrontal cortex and the bilateral amygdala in adult individuals with ASD in vivo. These imaging alterations point to an abnormal laminar cytoarchitecture and to an increased neuronal density, similar to what has been previously described in post‐mortem data in ASD. Our data demonstrate that it is possible to visualize, in vivo and at the individual level, alterations of cortical and subcortical microstructure in ASD. Future studies will be needed to extend these findings to a larger group of individuals and evaluate their association with symptomatology as well as their specificity among the different neurodevelopmental disorders.
Distribution and reference interval establishment of neutral‐to‐lymphocyte ratio (NLR), lymphocyte‐to‐monocyte ratio (LMR), and platelet‐to‐lymphocyte ratio (PLR) in Chinese healthy adults

Neutral‐to‐lymphocyte ratio (NLR), lymphocyte‐to‐monocyte ratio (LMR), and platelet‐to‐lymphocyte ratio (PLR) are associated with coronavirus disease 2019 (COVID‐19) and many diseases, but there are few data about the reference interval (RI) of NLR, LMR, and PLR.
Exploring community perceptions, attitudes and practices regarding the COVID-19 pandemic in Karachi, Pakistan

Background The Government of Pakistan is facing difficulty to contain the surge of COVID-19 due to the country’s social, political, economical and cultural context. Experiences from the previous epidemic suggest that community perceptions, social norms and cultural practices can impede COVID-19 containment. To understand social responses towards COVID-19, the study aims to explore the understanding of COVID-19 and the acceptance of control measures among community members. Methods We conducted an exploratory qualitative study using a purposive sampling approach, at two communities of Karachi, Pakistan. In-depth interviews were conducted with community members including, young, middle-aged and older adults of both genders. Study data were analysed manually using the conventional content analysis technique. Results A total of 27 in-depth virtual interviews were conducted, between May and June 2020. Six overarching themes were identified: (1) community knowledge and perceptions around COVID-19; (2) trusted and preferred sources of health information; (3) initial thoughts and feeling towards COVID-19 pandemic; (4) community practices to prevent exposure from COVID-19; (5) perceived risks associated with poor adherence to infection control practices; and (6) future preparedness of community to avoid the second wave of the outbreak. Generally, community members had good knowledge about COVID-19, and positive behaviour and attitude towards using standard precautions. The knowledge is mainly acquired through electronic, print and social media platforms, which have pros and cons. However, some community members including younger individuals had poor adherence to safety measures. This may necessitate concentrated efforts to raise awareness through community mobilisation and sensitisation activities. Conclusion This study provides an initial evidence base of communities’ perceptions, and attitudes towards COVID-19 in an early stage of pandemic. The study emphasises that sufficient knowledge and awareness about COVID-19, adequate training and drills, and adherence to safety measures, are necessary to better prepare for the second wave of COVID-19.
Implementation of the kidney team at home intervention: Evaluating generalizability, implementation process, and effects

Research has shown that a home‐based educational intervention for patients with chronic kidney disease results in better knowledge and communication, and more living donor kidney transplantations (LDKT). Implementation research in the field of renal care is almost nonexistent. The aims of this study were (1) to demonstrate generalizability, (2) evaluate the implementation process, and (3) to assess the relationship of intervention effects on LDKT‐activity. Eight hospitals participated in the project. Patients eligible for all kidney replacement therapies (KRT) were invited to participate. Effect outcomes were KRT‐knowledge and KRT‐communication, and treatment choice. Feasibility, fidelity, and intervention costs were assessed as part of the process evaluation. Three hundred and thirty‐two patients completed the intervention. There was a significant increase in KRT‐knowledge and KRT‐communication among participants. One hundred and twenty‐nine out of 332 patients (39%) had LDKT‐activity, which was in line with the results of the clinical trials. Protocol adherence, knowledge, and age were correlated with LDKT‐activity. This unique implementation study shows that the results in practice are comparable to the previous trials, and show that the intervention can be implemented, while maintaining quality. Results from the project resulted in the uptake of the intervention in standard care. We urge other countries to investigate the uptake of the intervention.
Reply to “CSF Cytokine Profiles Do Not Reliably Delineate Encephalopathy and Inflammation in Neuro‐COVID”

In reply to Drs Finsterer and Scorza’s comments, patients presented diverse cerebrospinal fluid (CSF) profiles regarding markers of neuroinflammation and neurodegeneration, and biochemical and cellular findings, even among patients with the same neurological condition. The same applied to inflammatory cytokines. On average, CSF and serum cytokine patterns were distinct, which underscored the chronology of events triggering neurological manifestations. CSF elevation of cytokines in inflammatory neurological diseases (IND) did not reflect a respective increase in serum. Conversely, encephalopathy was associated with higher serum interleukin 6, C-X-C motif chemokine ligand 8 (CXCL8), and transforming growth factor β1 levels, but cytokines in the CSF did not differ from controls in most cases. An altered blood–brain barrier and a traumatic spinal tap could influence these results. However, red blood cell (RBC) counts in the CSF were adequate (4 RBC/mm, interquartile range = 0–33), except for 2 patients with encephalopathy with 2,048 and 5,547 RBC/ mm. Their exclusion, however, did not alter the findings. Thus, CSF cytokine profiles were not influenced by serum contamination. Moreover, a correlation analysis showed that CSF and serum levels of cytokines were independent, except for CXCL10 in patients with encephalopathy (Table), which was not altered as compared to controls. Patients were organized by their primary neurological manifestation at the time of CSF collection. One patient was diagnosed with neuromyelitis optica, but anti– aquaporin 4 was not tested. Patients with refractory headache presented normal brain magnetic resonance imaging (MRI), but 85% had CSF opening pressure > 200mmH2O, and half had idiopathic intracranial hypertension (>250mmH2O). 3 Seizures and abnormalities on electroencephalogram were considered for diagnosis of both encephalopathy and encephalitis. However, to avoid overlap between groups, encephalopathy was disregarded whenever signs of acute brain inflammation were present, including pleocytosis and/or brain MRI changes, which instead characterized encephalitis. Although headache may precede encephalopathy or IND, sequential onset between encephalopathy and IND can be ruled out in our study, because such conditions presented as first manifestations within 14 days from the onset of COVID-19. Therefore, CSF findings were unlikely to be associated with distinct stages of the same disease. Lastly, prospective analysis of patients would illuminate the dynamics of cytokines and biomarkers of inflammation. However, the study was conducted between April and June 2020, at the beginning
Deciphering Neurodegenerative Diseases Using Long-Read Sequencing

Neurodegenerative diseases exhibit chronic progressive lesions in the central and peripheral nervous systems with unclear causes. The search for pathogenic mutations in human neurodegenerative diseases has benefited from massively parallel short-read sequencers. However, genomic regions, including repetitive elements, especially with high/low GC content, are far beyond the capability of conventional approaches. Recently, long-read single-molecule DNA sequencing technologies have emerged and enabled researchers to study genomes, transcriptomes, and metagenomes at unprecedented resolutions. The identification of novel mutations in unresolved neurodegenerative disorders, the characterization of causative repeat expansions, and the direct detection of epigenetic modifications on naive DNA by virtue of long-read sequencers will further expand our understanding of neurodegenerative diseases. In this article, we review and compare 2 prevailing long-read sequencing technologies, Pacific Biosciences and Oxford Nanopore Technologies, and discuss their applications in neurodegenerative diseases.
Annealing Temperature Effect on the Physical Properties of Titanium Oxide Thin Films Prepared by the Sol-Gel Method

In this work, the low-cost sol–gel, spin-coating technique was used to grow TiO2 thin films on silicon substrates. The influence of annealing temperature on the structural, morphological, and optical properties of TiO2 films is investigated. The structural properties of the TiO2 films are investigated by Raman and Fourier transform infrared (FTIR) Spectroscopy. Morphological properties are studied by Atomic Force Microscopy (AFM). The optical properties are examined by photoluminescence (PL) and ultraviolet-visible (UV-vis) spectroscopy.
β6-Integrin Serves as a Potential Serum Marker for Diagnosis and Prognosis of Pancreatic Adenocarcinoma

INTRODUCTION: Despite enormous efforts during the past decades, pancreatic adenocarcinoma (PAC) remains one of the most deleterious cancer entities. A useful biomarker for early detection or prognosis of PAC does not yet exist. The goal of our study was the characterization of β6-integrin (ITGB6) as a novel serum tumor marker for refined diagnosis and prognosis of PAC. Serum ITGB6 levels were analyzed in 3 independent PAC cohorts consisting of retrospectively and prospectively collected serum and/or (metastatic) PAC tissue specimens. METHODS: Using 2 independent cohorts, we measured serum ITGB6 concentrations in 10 chronic pancreatitis patients, 10 controls, as well as in 27 (cohort 1) and 24 (cohort 2) patients with PAC, respectively. In these patients, we investigated whether ITGB6 serum levels correlate with known clinical and prognostic markers for PAC and whether they might differ between patients with PAC or benign inflammatory diseases of the pancreas. RESULTS: We found that elevated serum ITGB6 levels (≥0.100 ng/mL) in patients suffering from metastasizing PAC presented an unfavorable prognostic outcome. By correlating the ITGB6 tissue expression in primary and metastatic PAC with clinical parameters, we found that positive ITGB6 expression in the tumor tissue is linked to increased serum ITGB6 levels in nonmetastatic PAC and correlates with carbohydrate antigen 19-9 and clinical outcome. DISCUSSION: Our findings suggest that ITGB6 might serve as a novel serum biomarker for early diagnosis and prognosis of PAC. Given the limited specificity and sensitivity of currently used carbohydrate antigen 19-9–based assays, ITGB6 may have the potential to improve the diagnostic accuracy for PAC.
Concurrent cardiac transthyretin and brain β amyloid accumulation among the older adults: The Hisayama study

Previous studies have revealed risk for cognitive impairment in cardiovascular diseases. We investigated the relationship between degenerative changes of the brain and heart, with reference to Alzheimer's disease (AD) pathologies, cardiac transthyretin amyloid (ATTR) deposition, and cardiac fibrosis. A total of 240 consecutive autopsy cases of a Japanese population‐based study were examined. β amyloid (Aβ) of senile plaques, phosphorylated tau protein of neurofibrillary tangles, and ATTR in the hearts were immunohistochemically detected and graded according to the NIH‐AA guideline for AD pathology and as Tanskanen reported, respectively. Cerebral amyloid angiopathy (CAA) was graded according to the Vonsattel scale. Cardiac fibrosis was detected by picrosirius red staining, followed by image analysis. Cardiac ATTR deposition occurred after age 75 years and increased in an age‐dependent manner. ATTR deposition was more common, and of higher grades, in the dementia cases. We subdivided the cases into two age groups: ≤90 years old (n = 173) and >90 years old (n = 67), which was the mean and median age at death of the AD cases. When adjusted for age and sex, TTR deposition grades correlated with Aβ phase score (A2–3), the Consortium to Establish a Registry for AD score (sparse to frequent), and high Braak stage (V–VI) only in those aged ≤90 years at death. No significant correlation was observed between the cardiac ATTR deposition and CAA stages, or between cardiac fibrosis and AD pathologies. Collectively, AD brain pathology correlated with cardiac TTR deposition among the older adults ≤90 years.
