Objective: To investigate the epidemiological characteristics and genotypes of human papillomavirus (HPV) infection in Mianyang. Methods: The cervical samples of 27,040 patients, who visited the Department of Gynecology of The Third Hospital of Mianyang from January 2018 to January 2020, were collected. Results: The HPV-positive infection rate was 21.40% (5,787/27,040); the single HPV infection rate was 72.04% (4,169/5,787); the double HPV infection rate was 19.73% (1,142/5,787); the triple and above HPV infection rate was 8.22% (476/5,787); the top five high-risk HPV subtypes with the highest infection rates were HPV52, 16, 58, 53, and 51, while the top five low-risk HPV subtypes with the highest infection rates were HPV81, 42, 43, 6, and 11; there were significant differences in the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate among different age groups (P < 0.05). Conclusion: The HPV infection rate in Mianyang was 21.4%, in which the majority of the cases were single infection; the high-risk HPV subtypes were HPV52, 16, 58, 53, and 51; the HPV-positive infection rate, high-risk infection rate, low-risk infection rate, and multiple infection rate were high in the middle but low at both ends in the context of age distribution; the top three age groups with the highest infection rates were 45-49, 40-44, and 30-34.

Since its emergence in 2019 SARS-CoV-2 has proven to have a higher level of morbidity and mortality compared to the other prevailing coronaviruses. Although initially most African countries were spared from the devastating effect of SARS-CoV-2, at present almost every country has been affected. Although no association has been established between being HIV-1-infected and being more vulnerable to contracting COVID-19, HIV-1-infected individuals have a greater risk of developing severe COVID-19 and of COVID-19 related mortality. The rapid development of the various types of COVID-19 vaccines has gone a long way in mitigating the devastating effects of the virus and has controlled its spread. However, global vaccine deployment has been uneven particularly in Africa. The emergence of SARS-CoV-2 variants, such as Beta and Delta, which seem to show some subtle resistance to the existing vaccines, suggests COVID-19 will still be a high-risk infection for years. In this review we report on the current impact of COVID-19 on HIV-1-infected individuals from an immunological perspective and attempt to make a case for prioritising COVID-19 vaccination for those living with HIV-1 in Sub-Saharan Africa (SSA) countries like Malawi as one way of minimising the impact of COVID-19 in these countries.

AbstractAerosol transmission has been a pathway for virus spread for many viruses. Similarly, emerging evidence regarding SARS-CoV-2, and the resulting pandemic as declared by WHO in March 2020, determined aerosol transmission for SARS-CoV-2 to be significant. As such, public health officials and professionals have sought data regarding the effect of Heating, Ventilation, and Air Conditioning (HVAC) features to control and mitigate viruses, particularly coronaviruses. A systematic review was conducted using international standards to identify and comprehensively synthesize research examining the effectiveness of ventilation for mitigating transmission of coronaviruses. The results from 32 relevant studies showed that: increased ventilation rate was associated with decreased transmission, transmission probability/risk, infection probability/risk, droplet persistence, virus concentration, and increased virus removal and virus particle removal efficiency; increased ventilation rate decreased risk at longer exposure times; some ventilation was better than no ventilation; airflow patterns affected transmission; ventilation feature (e.g., supply/exhaust, fans) placement influenced particle distribution. Some studies provided qualitative recommendations; however, few provided specific quantitative ventilation parameters suggesting a significant gap in current research. Adapting HVAC ventilation systems to mitigate virus transmission is not a one-solution-fits-all approach but instead requires consideration of factors such as ventilation rate, airflow patterns, air balancing, occupancy, and feature placement.Practical ImplicationsIncreasing ventilation, whether through ventilation rates (ACH, m3/h, m3/min, L/min) or as determined by CO2 levels (ppm), is associated with decreased transmission, transmission probability/risk, infection probability/risk, droplet persistence, and virus concentration, and increased virus removal and efficiency of virus particle removal. As well, professionals should consider the fact that changing ventilation rate or using mixing ventilation is not always the only way to mitigate and control viruses as varying airflow patterns and the use of ventilation resulted in better outcomes than situations without ventilation. Practitioners also need to consider occupancy, ventilation feature (supply/exhaust and fans) placement, and exposure time in conjunction with both ventilation rates and airflow patterns. Some recommendations with quantified data were made, including using an air change rate of 9 h-1 for a hospital ward; waiting six air changes or 2.5 hours before allowing different individuals into an unfiltered office with ∼2 fresh air changes (FCH) and one air change for a high-efficiency MERV or HEPA filtered laboratory; and using a pressure difference between -2 and -25 Pa in negative pressure isolation spaces. Other recommendations for practice included using or increasing ventilation, introducing fresh air, using maximum supply rates, avoiding poorly ventilated spaces, assessing fan placement and potentially increasing ventilation locations, and employing ventilation testing and air balancing checks.

The pandemic has affected every facet of human life. Apart from individual’s psychological and mental health issues, the concern regarding mobility, access and communication with high risk infection is a challenging situation. People with disability are more likely vulnerable to infections. The new changes in our social lifestyle (social distancing, limiting touch) can profoundly impact the day today life of people with disability. In this paper, we will briefly discuss the situation faced by individuals with disabilities, some known remedies, and yet to be identified and curated technological remedies; the impact due to transition of special education toward online mode. Tips and tricks for better utilization of work from home concept by people with disabilities. Accessibility must be universal, accommodating all and encouraging inclusivity. As rightly said by Helen Keller, “The only thing worse than being blind is having sight but no vision”; subsequently, going by the demand of the time, we should contribute toward the universal design approach by supporting people with disabilities and commit to the changes required in disability care to reduce the impact of pandemic.

Background: The present study analysed SARS-CoV-2 cases observed in Sicily and investigated social determinants that could have an impact on the virus spread. Methods: SARS-CoV-2 cases observed among Sicilian residents between the 1 February 2020 and 15 October 2020 have been included in the analyses. Age, sex, date of infection detection, residency, clinical outcomes, and exposure route have been evaluated. Each case has been linked to the census section of residency and its socio-demographic data. Results: A total of 10,114 patients (202.3 cases per 100,000 residents; 95% CI = 198.4–206.2) were analysed: 45.4% were asymptomatic and 3.62% were deceased during follow-up. Asymptomatic or mild cases were more frequent among young groups. A multivariable analysis found a reduced risk of SARS-CoV-2 cases was found in census sections with higher male prevalence (adj-OR = 0.99, 95% CI = 0.99–0.99; p < 0.001) and presence of immigrants (adj-OR = 0.89, 95% CI 0.86–0.92; p < 0.001). Proportion of residents aged <15 years, residents with a university degree, residents with secondary education, extra-urban mobility, presence of home for rent, and presence of more than five homes per building were found to increase the risk of SARS-CoV-2 incidence. Conclusion: Routinely collected socio-demographic data can be predictors of SARS-CoV-2 risk infection and they may have a role in mapping high risk micro-areas for virus transmission.

Fish pedicure (feet immersion in a tank containing fish Garra rufa or Cyprinion macrostomus) is a widely diffuse cosmetic practice, usually considered safe. However, this practice is regulated only in a few Countries, and the risk of infection related to this practice is not quantified. We report a case of bilateral symmetric ankles and feet cellulitis in a previously healthy young woman without risk factors for infections, after a fish pedicure in Greece. Three cases of foot infection after fish pedicure have been described in the English literature, two sustained by S. aureus and one by Mycobacterium marinum, but none of them was so extensive, involving not only feet but also ankles. The practice of the aesthetic fish pedicure should be regulated in all Countries to reduce the risk of complications related to this procedure. Moreover, studies targeted at investigating the risk of infection associated with this procedure are warranted. Keywords: Fish pedicure; Cosmetic procedure; Cellulitis; Risk infection.

Based on the clinical experience, it has been observed that when it comes to the impact of SARS-CoV-2 virus on the cardiovascular system, it is significant. In patients with COVID-19 infection, the development of myocarditis occurs a few days after the onset of fever. The mechanism of myocardial injury alone, as well as most pathologies caused by the SARS-CoV-2 virus, is the subject of research by many experts, but two basic ways can certainly be assumed: a direct toxic effect of SARS-CoV-2 on myocardial cells and another possible way of myocardial injury is to activate the innate immune response by releasing proinflammatory cytokines, as well as to activate the adaptive mechanisms of the autoimmune type by molecular mimicry. The approach to treatment is the same as for other viral myocarditis; it is non-specific, applied supportive treatment, such as anti-inflammatory drugs, low-dose corticosteroid therapy, and immunoglobulins. The aim of this review is to present the previous experiences of physicians around the world on the clinical presentation of myocarditis caused by COVID-19 infection, diagnostic and therapeutic approach in a specific situation of high-risk infection.

Purpose The purpose of this paper is to analyze the network path and internal mechanism of risks’ cross-contagion between shadow banks and design strategies for preventing risk infection between shadow banks. Design/methodology/approach Using the complex network theory, analyze the mechanism of risks’ cross-contagion between shadow banks from the credit network, business relationship network (BRN) and social network (SN); the cross-contagion mechanism using the structural equation model on the basis of China’s shadow banks is tested; based on the three risk infection paths, the prevention and control strategies for risk infection using the mathematical models of epidemic diseases are designed. Findings There are three network risk contagion paths between shadow banks. One, the credit network, risks are infected crossly mainly through debt and equity relationships; two, the BRN, risks are infected crossly mainly through business network and macro policy transmission; three, investor SN, risks are infected crossly mainly through individual SN and fractal relationships. The following three strategies for preventing risk’s cross-contagion between shadow banks: one, the in advance preventing strategy is more effective than the ex post control strategy; two, increasing the risk management coefficient; three, reducing the number of risk-infected submarkets. Originality/value The research of this study, especially the strategies for preventing the risks’ cross-contagion, could provide theoretical and practical guidance for regulatory authorities in formulating risk supervision measures.

Abstract Silages can harbor pathogenic and antimicrobial resistant microbes which risk infection of food-producing animals. Livestock producers need effective yet environmentally friendly interventions to preserve the feed value of these fermented materials. Medium chain fatty acids such as laurate and its glycerol monoester, monolaurin, are potent inhibitors of many Gram-positive bacteria and when tested at 5 mg/mL in anaerobic cultures (n = 3/treatment) inoculated with 105 colony forming units (CFU) of Listeria monocytogenes and grown at 37oC in ½ strength Brain Heart infusion broth achieved near complete elimination of viable cells after 6 h compared to a 2.2 ± 0.1 log10 CFU/mL increase observed in controls. Culture of a tetracycline-resistant Enterococcus faecalis with 5 mg laurate/mL likewise achieved near complete elimination of viable cells (5 log10 CFU/mL) by 6 h incubation. The bactericidal effect of 5 mg monolaurin was less against E. faecalis, achieving a decrease of 1.8 ± 0.2 log10 CFU/mL and not decreased further after 24 h. When tested against air-exposed silage, pH 7.53 (4 g), mixed with 4 mL water, 5 mg laurate or monolaurin decreased viability of experimentally-inoculated L. monocytogenes (105 CFU/g silage) more (P &lt; 0.05) than untreated controls after 24 h aerobic incubation (22oC), with viable counts being decreased 6.3 ± 0.1, 5.9 ± 0.8 and 4.5 ± 0.1 log10 CFU/g, respectively. In contrast, viable recovery of the experimentally-inoculated (105 CFU/g) tetracycline-resistant E. faecalis was reduced more (P &lt; 0.05) than controls (decreased 0.7 ± 0.1 log10 CFU/g) after 6 h incubation when similarly tested with laurate and monolaurin (1.7 ± 0.5 and 3.0 ± 0.9 log10 CFU/g, respectively) but counts after 24 h were similar, decreasing on average 2.0 ± 0.5 log10 CFU/g). Results indicate laurate and monolaurin may be useful in killing L. monocytogenes and tetracycline-resistant E. faecalis during silage feed-out.
