Compliance with COVID-19 public health guidelines: an attitude-behaviour gap bridged by personal concern and distance to conspiracy ideation

Abstract Objective This study examined predictors of compliance with public health guidelines to curb transmission of COVID-19. Design Applying an exploratory longitudinal design, participants (N = 431) from Germany and Austria completed surveys in April/May 2020 (T1) and July/August 2020 (T2). Measures Three outcome measures operationalised compliance with public health guidelines at T2: self-reported adherence (behavioural), agreement and opposition (attitudinal). At T1, demographics, perceived distress (PHQ-4, crisis of meaning), resources (self-control, meaningfulness), locus of control, conspiracy mentality and social media use were assessed. At T2, situational variables were added (person at risk, infection of close person, fear of infection, COVID-19 stress). Temporal shifts from T1 to T2 were examined as complementary information. Results An attitude-behaviour gap at T2 was identified, as agreement with and opposition to the guidelines were only modestly correlated with adherence to them. Measures of personal concern (fear of infection, person at risk) were associated with both adherence and positive attitudes towards the measures. COVID-19 stress and conspiracy mentality predicted negative attitudes, but not adherence. Age predicted adherence positively, social media use negatively. Conclusion The findings support the significance of personal concern for compliance with public health guidelines and suggest a critical impact of social media use and conspiracy mentality.
Gene Therapies for the Treatment of Leber Hereditary Optic Neuropathy

Leber hereditary optic neuropathy (LHON) is a rare, blinding, maternally inherited mitochondrial genetic disease in need of effective treatment. LHON is a nonsyndromic optic neuropathy affecting the retinal ganglion cells (RGCs), whose axons form the optic nerve and extend into the brain via the optic chiasm and optic tracts. The physiopathology of LHON is characterized by selective loss of RGCs and their axons, which leads to rapidly progressive bilateral central vision loss.
Relationship between Consulting for Second Medical Opinions, Radiotherapy, and Satisfaction with Therapy, Analyzed by Structural Equation Modeling: A Web-Based Survey

Objective: The radiotherapy utilization rate in Japan is lower than that in other developed countries. This study identified factors associated with the low rate, by conducting an online survey of Japanese cancer survivors. Methods: We reviewed the web survey results of Japanese cancer patients. The survey examined the process of choosing treatments and the actual treatment received. We included respondents whose most engaged-in treatment was either radiotherapy or surgery, dividing them into two groups. We used the chi-square test to compare the patients in the both groups for their impression of the therapy, decision-making approach, and decision to seek second medical opinions (SMOs). To assess the relationship between seeking SMOs, being most engaged in radiotherapy, and feeling satisfied, we used the structural equation modeling (SEM) approach. Results: We included 139 patients in the radiotherapy group and 681 patients in the surgery group. Compared with patients in the surgery group, more patients in the radiotherapy group sought SMOs (19% vs. 28%), shared opinions with their doctor (27% vs. 42%), and were satisfied with their treatment (69% vs. 78%). SEM analysis showed that seeking SMOs contributed to radiotherapy being the most-engaged-in therapy (β = 0.23; P < 0.01), and the treatment contributed to the satisfaction (β = 0.15; P < 0.01). Conclusion: Patients who underwent radiotherapy felt more satisfied with the treatment than patients who underwent surgery. Perceptions about radiotherapy and SMOs may be a reason for the low utilization of radiotherapy in Japan.
Perioperative Antibiotic Use in Sleep Surgery: Clinical Relevance

Objective Upper airway surgery is a common therapeutic approach recommended for patients with obstructive sleep apnea (OSA) to decrease disease burden. We aimed to evaluate the effect of perioperative antibiotic prescription on complication rates. Study Design Retrospective cohort (national database). Setting Tertiary referral center. Methods This is a retrospective study of a large national health care insurance database (Truven MarketScan) from 2007 to 2015. Subjects diagnosed with OSA who had uvulopalatopharyngoplasty (UPPP) were included and stratified in single versus multilevel surgery. Other variables included smoking, age, sex, antibiotic prescription, and comorbidities based on the Elixhauser index. Evaluated outcomes were postoperative bleeding, intubation, pneumonia, superficial surgical site infection, tracheostomy, and hospital readmission. A multivariate regression model was created to assess each complication. Results A total of 5,798,528 subjects received a diagnosis of OSA, of which 39,916 were >18 years old and underwent UPPP, either alone or with additional procedures. The mean age was 43 years, and 73.4% were male. Antibiotic prescription was associated with less bleeding in UPPP alone, UPPP with nasal surgery, and UPPP with nasal and tongue surgery (P < .001, P < .001, and P = .006, respectively). It was also associated with a lower prevalence of surgical site infection, pneumonia, tracheostomy, intubation, and hospital readmission (P < .001). On a multivariate model, antibiotic prescription was significantly associated with a decreased rate of complications. Conclusions Although former studies recommended against the use of antibiotics after tonsillectomy, our results suggest that antibiotic prescription after UPPP for OSA was associated with less bleeding, surgical site infection, pneumonia, intubation, tracheostomy, and hospital readmission 30 days postoperatively.
Fatores de risco para embolia pulmonar em pacientes com COVID-19 anticoagulados na unidade de terapia intensiva submetidos à angiografia por tomografia computadorizada

Objetivo Avaliar a incidência de embolia pulmonar, seu relacionamento com os níveis de dímero D e outros possíveis fatores associados, além dos efeitos adversos da anticoagulação e meios de contraste. Métodos Conduziu-se um estudo de coorte retrospectiva em um hospital público chileno. Foram incluídos os pacientes com idade acima de 18 anos com COVID-19, mecanicamente ventilados na unidade de terapia intensiva, admitidos entre março e junho de 2020. Todos os pacientes receberam tromboprofilaxia com heparina, que foi aumentada até uma dose de anticoagulação com níveis de dímero D acima de 3µg/mL. Resultados Foram acompanhados 127 pacientes, dos quais 73 foram submetidos à angiografia por tomografia computadorizada (média de idade de 54 ± 12 anos; 49 homens). Sessenta e dois dos 73 pacientes (84,9%) receberam anticoagulação total antes da angiografia por tomografia computadorizada. Além disso, 18 dos 73 pacientes tiveram embolia pulmonar (24,7%). Na comparação entre pacientes com e sem embolia pulmonar, não se observaram diferenças significantes em termos de idade, sexo, obesidade, tabagismo, escores de Wells e Genebra revisado, dímero D ou mortalidade. O uso de anticoagulantes foi similar em ambos os grupos. O número de dias desde o início da anticoagulação até a angiografia por tomografia computadorizada foi significantemente menor no grupo com embolia pulmonar (p = 0,002). Três pacientes tiveram lesão renal aguda após o contraste (4,1%), e um paciente teve sangramento importante. Conclusão Apesar da anticoagulação, um em cada quatro pacientes com COVID-19 submetidos à ventilação mecânica e avaliados com angiografia por tomografia computadorizada apresentou embolia pulmonar. Com uma maior demora para realização da angiografia por tomografia computadorizada após início de anticoagulação empírica, identificou-se um número significantemente menor de embolias
Intraoperative Electrocochleography in Subjects Affected by Vestibular Schwannoma and Ménière’s Disease: Comparison of Results

Objectives: Histologic reports of temporal bones of ears with vestibular schwannomas (VSs) have indicated findings of endolymphatic hydrops (ELH) in some cases. The main goal of this investigation was to test ears with VSs to determine if they exhibit electrophysiological characteristics similar to those of ears expected to experience ELH. Design: Fifty-three subjects with surgically confirmed VS aged ≥18 and with normal middle ear status were included in this study. In addition, a second group of adult subjects (n = 24) undergoing labyrinthectomy (n = 6) or endolymphatic sac decompression and shunt (ELS) placement (n = 18) for poorly controlled vestibular symptoms associated with Meniere’s disease (MD) participated in this research. Intraoperative electrocochleography (ECochG) from the round window was performed using tone burst stimuli. Audiometric testing and word recognition scores (WRS) were performed preoperatively. ECochG amplitudes, cochlear microphonic/auditory nerve neurophonic (ANN) in the form of the “ongoing” response and summation potential, were analyzed and compared between the two groups of subjects. In addition, to evaluate any effect of auditory nerve function, the auditory nerve score was calculated for each subject. Pure-tone averages were obtained using the average air conduction thresholds at 0.5, 1, and 2 kHz while WRS was assessed using Northwestern University Auditory Test No. 6 word lists. Results: In the VS group the average pure-tone averages and WRS were 59.6 dB HL and 44.8%, respectively, while in the MD group they were 52.3 dB HL and 73.8%. ECochG findings in both groups revealed a reduced trend in amplitude of the ongoing response with increased stimulus frequency. The summation potential amplitudes of subjects with VS were found to be less negative than the MD subjects for nearly all test frequencies. Finally, the VS group exhibited poorer amounts of auditory nerve function compared to the MD group. Conclusions: The current findings suggest cochlear pathology (e.g., hair cell loss) in both groups but do not support the hypothesis that VSs cause ELH.
The effects of tobacco and cannabis use on semen and endocrine parameters in infertile males

Abstract Substances such as tobacco and cannabis can negatively modulate seminal parameters and sex hormones and lead to fertility problems in males. The present study aimed to determine the effect of cigarettes, dipping tobacco, and cannabis on semen parameters and sex hormones in infertile males. A total of 160 infertile healthy participants (cigarette smokers n = 40, dipping tobacco users n = 40, cannabis users n = 40 and infertile controls n = 40) were included in the study. Fasting blood samples were collected from all the participants using the aseptic technique, and semen samples were collected by masturbation following sexual abstinence of 2–7 days. The levels of serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were determined using ELISA. The serum level of FSH was significantly higher in cannabis users relative to the control group (p = 0.043). A mild non-significant decrease in sperm count, serum LH and testosterone levels were observed in all drug users compared to controls. In conclusion, chronic use of tobacco and cannabis mildly modulates semen and hormonal parameters in infertile males.
Long-Term Recreational Cannabis Use Is Associated With Lower Executive Function and Processing Speed in a Pilot Sample of Older Adults

More older adults are using cannabis for recreational and/or medical purposes, but most studies examining cognitive function and cannabis use do not include older adults. The current small pilot study sought to compare cognitive function and emotional functioning among adults age 60 and older who were regular, primarily recreational cannabis users (n = 28) and nonusers (n = 10). A bimodal distribution was observed among cannabis users such that they had either initiated regular use more recently (“short-term” users; ≤7 years, n = 13) or earlier in life (“long-term” users; ≥19 years, n = 15). Nonusers, short-term, and long-term users were not different in depression, anxiety, or emotion regulation, or alcohol use. Nonusers scored significantly higher than long-term users in executive function. Short-term users scored significantly higher than long-term users in executive function, processing speed, and general cognition. Additionally, greater recent cannabis use frequency was negatively associated with working memory. The current findings suggest that short-term recreational cannabis use does not result in differences in cognitive performance compared to nonusers, which may indicate that short-term use is relatively benign in older adults. However, longer duration of use is associated with poorer processing speed and executive functioning, and more recent cannabis use is associated with poorer working memory, which may impact older adults’ overall cognitive functioning.
Observed dyadic racial socialization disrupts the association between frequent discriminatory experiences and emotional reactivity among Black adolescents.

Understanding the underlying mechanisms by which racism degrades mental health and the factors that disrupt these mechanisms is paramount. Black adolescents (Mage = 15.5) and their mothers (Mage = 44) were observed discussing a hypothetical discriminatory situation and surveyed about their discriminatory experiences (N = 110). Results indicated that adolescents' submissive emotional reactivity (e.g., sadness, embarrassment) in direct response to discrimination, rather than dominant reactivity (e.g., anger, frustration), was the primary mechanism explaining the link between discrimination and internalizing and externalizing symptoms. Maternal advocacy combined with high levels of dyadic warmth and emotion expression reduced girls' submissive reactivity, whereas a more directive "no-nonsense" advocacy approach reduced boys' submissive reactivity. Findings demonstrate how racial socialization can disrupt the pain of discrimination.
Functional Impairments in the Mental Health, Depression and Anxiety Related to the Viral Epidemic, and Disruption in Healthcare Service Utilization among Cancer Patients in the COVID-19 Pandemic Era

Purpose Literature is scarce regarding cancer care utilization during the massive outbreak of coronavirus disease 2019 (COVID-19) in the Republic of Korea. We investigated functional impairments in mental health and their relationships with depression, anxiety regarding the viral epidemic, and disruptions in healthcare service utilization among cancer patients in the COVID-19 pandemic era. Materials and Methods We used an online survey with questions related to the disturbances faced by patients with cancer in utilizing healthcare services in the pandemic era. Current mental health status was assessed using the Work and Social Adjustment Scale (WSAS), Stress and Anxiety to Viral Epidemics-6 (SAVE-6) scale, Patient Health Questionnaire-9 (PHQ-9), Insomnia Severity Index (ISI), Brief Resilience Scale (BRS), Cancer-Related Dysfunctional Beliefs about Sleep Scale (C-DBS), and Fear of COVID-19 over Cancer (FCC). Results Among the 221 responders, 95 (43.0%) reported disruptions in healthcare service utilization during the COVID-19 pandemic. Logistic regression analysis revealed that functional impairment in the mental health of these patients was expected due to disruptions in healthcare service utilization, high levels of depression, anxiety regarding the viral epidemic, fear of COVID over cancer, and low resilience. Mediation analysis showed that patient resilience and cancer-related dysfunctional beliefs about sleep partially mediated the effects of viral anxiety on functional impairment. Conclusion In this pandemic era, patients with cancer experience depression, anxiety regarding the viral epidemic, and disruptions in healthcare service utilization, which may influence their functional impairments in mental health.
Prevalence of Tobacco Use in Young Adult Literate Girls of 18-25 Years in Meghalaya, India: A Cross-Sectional Study

Background: Several national-level surveys have recognized a high prevalence of tobacco use in North-eastern (NE) India. However, information on tobacco use in specific population subgroups still lacks from the region. The present study determines the prevalence and influence of determinants like education and family income on tobacco use in senior school and college-going girls in Shillong, Meghalaya. Additionally, the prevalence of dual use of smoking and smokeless (SLT) tobacco with alcohol and non-tobacco Pan Masala has been examined. Methods: A cross-sectional study was conducted among 18-25 years girls in educational institutions in Shillong. Data were analysed using statistical software SPSS version 22. The categorical data presented as frequency (%). Chi-square was employed to see the association between variables. Results: (i) 8.10% of girls were current users of all forms of tobacco; 1.85% were smokers, 4.0% used SLT, and 2.25% were dual users of tobacco (ii) Of the 6.25% current users of SLT, 5.4% used a single smokeless tobacco product whereas 0.85% used multiple products of SLT (iii) 79.5% of tobacco smokers and 30.2% of current SLT users were dual users with alcohol (iv) 37.2% tobacco smokers and 18.5% SLT users were dual users with non-tobacco Pan Masala (v) Tobacco smoking was positively associated with educational status and family income whereas SLT use was independent of educational status and income of girls’ families. Conclusions: The study shows a relatively high prevalence of tobacco use and dual tobacco use with alcohol in the study population of educated young adult girls, underscoring a public health concern. It is recommended that an education-based comprehensive awareness program be initiated for tobacco and alcohol control in Meghalaya to improve knowledge and health-seeking behaviour change in this high- risk subgroup to control increasing NCDs.
Glycocalyx crowding with mucin mimetics strengthens binding of soluble and virus-associated lectins to host cell glycan receptors

Significance Like other animal hosts, humans are constantly challenged by pathogens. This has led to an evolution of physical barriers coating all mucosal tissues, which are most vulnerable to infection. An important part of this defense is a dense brush of large proteins, called mucins, which are heavily decorated with sugars and keep pathogens at bay. Deciphering how pathogens overcome the mucin barrier is necessary to understand early stages of infection and to develop more effective treatments. By artificially installing a mucin-like shield on the surfaces of cells using synthetic sugar–bearing polymers, we have discovered a physical mechanism by which proteins and viruses can exploit this barrier to adhere to their targets more strongly. Membrane-associated mucins protect epithelial cell surfaces against pathogenic threats by serving as nonproductive decoys that capture infectious agents and clear them from the cell surface and by erecting a physical barrier that restricts their access to target receptors on host cells. However, the mechanisms through which mucins function are still poorly defined because of a limited repertoire of tools available for tailoring their structure and composition in living cells with molecular precision. Using synthetic glycopolymer mimetics of mucins, we modeled the mucosal glycocalyx on red blood cells (RBCs) and evaluated its influence on lectin (SNA) and virus (H1N1) adhesion to endogenous sialic acid receptors. The glycocalyx inhibited the rate of SNA and H1N1 adhesion in a size- and density-dependent manner, consistent with the current view of mucins as providing a protective shield against pathogens. Counterintuitively, increasing the density of the mucin mimetics enhanced the retention of bound lectins and viruses. Careful characterization of SNA behavior at the RBC surface using a range of biophysical and imaging techniques revealed lectin-induced crowding and reorganization of the glycocalyx with concomitant enhancement in lectin clustering, presumably through the formation of a more extensive glycan receptor patch at the cell membrane. Our findings indicate that glycan-targeting pathogens may exploit the biophysical and biomechanical properties of mucins to overcome the mucosal glycocalyx barrier.
Prevalence of Dyslipidemia and Availability of Lipid-Lowering Medications Among Primary Health Care Settings in China

Key Points Question What is the prevalence of dyslipidemia in Chinese adults and what are the treatment and control rates of elevated low-density lipoprotein cholesterol in both primary and secondary prevention populations? Findings In this cross-sectional study of 2 314 538 community residents, 33.8% had dyslipidemia, 3.2% had established atherosclerotic cardiovascular disease (ASCVD), and 10.2% had high risk of ASCVD; 26.6% of those with ASCVD and 42.9% of those at high risk of ASCVD achieved low-density lipoprotein cholesterol control targets. Statins were available in 49.7% of the primary care institutions surveyed, with the lowest availability in rural village clinics. Meaning These findings suggest that dyslipidemia has become a major public health problem in China and is often inadequately treated and uncontrolled.
H5Nx Viruses Emerged during the Suppression of H5N1 Virus Populations in Poultry

A major shift in the ecology of highly pathogenic avian influenza (HPAI) H5 viruses occurred from 2008 to 2014, when viruses with non-N1 neuraminidase genes (termed H5Nx viruses) emerged and caused global H5 virus outbreaks. Here, we demonstrate that nationwide control measures, including vaccination in China, successfully suppressed H5N1 populations in poultry, providing an opportunity for antigenically distinct H5Nx viruses to emerge. ABSTRACT Highly pathogenic avian influenza (HPAI) H5 viruses have posed a substantial pandemic threat through repeated human infection since their emergence in China in 1996. Nationwide control measures, including vaccination of poultry, were implemented in 2005, leading to a sharp reduction in H5N1 virus outbreaks. In 2008, novel non-N1 subtype (H5Nx) viruses emerged, gradually replacing the dominant H5N1 subtype and causing global outbreaks. The cause of this major shift in the ecology of HPAI H5 viruses remains unknown. Here, we show that major H5N1 virus lineages underwent population bottlenecks in 2006, followed by a recovery in virus populations between 2007 and 2009. Our analyses indicate that control measures, not competition from H5Nx viruses, were responsible for the H5N1 decline, with an H5N1 lineage capable of infecting poultry and wild birds experiencing a less severe population bottleneck due to circulation in unaffected wild birds. We show that H5Nx viruses emerged during the successful suppression of H5N1 virus populations in poultry, providing an opportunity for antigenically distinct H5Nx viruses to propagate. Avian influenza vaccination programs would benefit from universal vaccines targeting a wider diversity of influenza viruses to prevent the emergence of novel subtypes. IMPORTANCE A major shift in the ecology of highly pathogenic avian influenza (HPAI) H5 viruses occurred from 2008 to 2014, when viruses with non-N1 neuraminidase genes (termed H5Nx viruses) emerged and caused global H5 virus outbreaks. Here, we demonstrate that nationwide control measures, including vaccination in China, successfully suppressed H5N1 populations in poultry, providing an opportunity for antigenically distinct H5Nx viruses to emerge. In particular, we show that the widespread use of H5N1 vaccines likely conferred a fitness advantage to H5Nx viruses due to the antigenic mismatch of the neuraminidase genes. These results indicate that avian influenza vaccination programs would benefit from universal vaccines that target a wider diversity of influenza viruses to prevent potential emergence of novel subtypes.
