Knowledge and Attitude towards Human Papilloma Virus Infection, Vaccines, and Cervical Cancer Prevention among School Students in Kano, Nigeria

The rising cases of human papillomavirus (HPV) infection and cervical cancer cases in Nigeria are alarming. Only a few studies have looked at secondary school students in Nigeria’s understanding of HPV infection and vaccine acceptance, whereas earlier studies have mostly focused on screening. In this study, 400 students from two secondary schools in Kano State, Nigeria, were engaged with the aim of assessing their level of knowledge and attitudes regarding HPV infection. The study further seeks to understand the respondent’s opinion on HPV vaccination and sensitize them to the health effects of HPV infection, thereby communicating the findings to the authorities concerned with policy making. The study revealed that only 128 (32%) and 142 (35.5%) respondents have knowledge about HPV and cervical cancer, respectively. Furthermore, none of the respondents were administered the HPV vaccine, with 81% of them not ready to take the vaccine. It was observed that the majority of the respondents (91%) believed that early hospital visits could help in mitigating HPV or cervical cancer cases. Following their sensitization, the respondents were observed to have different levels of satisfaction, ranging from very satisfied and satisfied to not satisfied. Effective awareness creation amongst students as well as parents is therefore essential in HPV vaccination projects, as well as in reducing the burden of cervical cancer in Nigeria.

Characterization of Canine Adenovirus Type 2 Virus Infection Pattern in Canine and Human Cell Lines

Canine adenovirus type 2 (CAV2) is a nonhuman adenovirus with a known ability to infect human and canine cells. The cell surface receptors involved in CAV2 transduction are still unknown. Identification of these would provide valuable information to develop enhanced gene delivery tools and better understand CAV2 biology. CAV2 is erroneously grouped with Ad5 based on the knowledge that CAV2 may transduce using CAR. Therefore, we have evaluated CAV2 and Ad5 (CAV2GFP, Ad5G/L) infection patterns in various canine and human cell lines to determine their different tropisms. Our research demonstrates that CAV2 can successfully infect cells that Ad5 does not infect, and CAV2 infections do not correlate with CAR expression. CAV2 can infect cells that have a low or minimal expression of CAR. Our data suggest that CAV2 transduction is not dependent on the CAR receptor, and thus, it is crucial to find novel CAV2 receptors.

The Use of Mebendazole in COVID-19 Patients: An Observational Retrospective Single Center Study

Background. An in-silico screen identified mebendazole with potential antiviral activity that could be a repurposed drug against SARS-CoV-2. Mebendazole is a well-tolerated and cheap antihelminthic agent that is readily available worldwide and thus could be a therapeutic tool in the fight against COVID-19. Methods. This is an observational retrospective study of PCR-confirmed COVID-19 patients who received mebendazole with the intention-to-treat. The study included an inpatient cohort (157 inpatients) and an outpatient cohort (185 outpatients). Of the 157 inpatients and 185 outpatients, 68 (43.3%) and 94 (50.8%) received mebendazole, respectively. Patients who presented within the same timeframe but did not receive mebendazole were used as controls. Patients received standard-of-care treatment including remdesivir, dexamethasone, and anticoagulants as deemed necessary by the treating physician. The following clinical outcomes were evaluated: for the inpatient cohort, length of stay (LOS) at the hospital, need for ventilation (combined invasive and noninvasive), and mortality; for the outpatient cohort, time to symptom resolution, need for hospitalization, and mortality. Results. For the inpatient cohort, the median age did not differ between the treatment and control groups; 62 (56, 67) vs. 62 (56, 68), , and there was a comparable proportion of males in both groups; 43 (63%) vs. 55 (62%), . The hospital LOS was 3.5 days shorter in the treatment group compared to the control group (). There were fewer patients who required invasive or noninvasive ventilation in the treatment group, 2 (2.9%) vs. 7 (7.9%), and the mortality rate is lower in the treatment group, 3 (4.4%) vs. 8 (9.0%), though the differences did not reach statistical significance. For the outpatient cohort, the median age was lower in the treatment group compared with the control group; 40 (34, 48) vs. 48 (41, 54), . There was a comparable proportion of males between both groups; 50 (53%) vs. 52 (57%), . Patients in the treatment group were 3.3 days closer to symptom resolution (). There were numerically fewer patients requiring hospitalization in the treatment group compared with the control group, 3 (3.2%) vs. 6 (6.6%), though this did not reach statistical significance (). Conclusion. In this retrospective observational study, the use of mebendazole in COVID-19 patients was associated with shorter hospitalizations in the inpatient cohort and shorter durations of symptom resolution in the outpatient cohort. The findings from this small observational study are hypothesis-generating and preclude drawing conclusions about clinical efficacy. Further studies are needed to examine the role of mebendazole in the treatment of COVID-19 patients.

Emergency Use of Tocilizumab in Moderate and Severe COVID-19 Patients over the Prevaccination Stage during the Pandemic in Mexico

Introduction. COVID-19 has been associated with the overactivation of the immune system; interleukin-6 (IL-6) seems to have a key role, which made its moderation to be proposed as a therapeutic blank. Tocilizumab has been used as part of treatments to modulate the immune response to infections caused by COVID-19. Material and Methods. An observational, descriptive, retrospective, and transversal study was carried out in patients diagnosed with moderate-severe COVID-19 who were hospitalized in the 251 General Regional Hospital from March to December 2020. Results. A review of 700 files corresponding to hospitalized patients was carried out, and a sample of 70 patients who met the inclusion criteria proposed for this protocol was obtained. Among the comorbidities associated with the disease, it was found that hypertensive patients have a higher mortality rate: 62% died and so did 59% of those who needed invasive respiratory support. As regards admission tests, statistical significance was found for the figures of leukocytes, neutrophils, glomerular filtration rate, and PCR. Conclusion. The use of this drug benefits mainly young nonhypertensive patients with a moderate disease and preserved renal functions with no need for invasive respiratory support, regardless of other comorbidities.

Hepatitis A and E Viruses in Mussels from Cherrat Estuary in Morocco: Detection by Real-Time Reverse Transcription PCR Analysis

The aim of the present study was to evaluate hepatitis A virus (HAV) and hepatitis E virus (HEV) contamination in mussels (Mytilus galloprovincialis) from Cherrat estuary (Moroccan Atlantic Coast), Morocco. In total, 52 samples (n = 12 mussels/each) were collected at four sites in the estuary, monthly, between March 2019 and March 2020. HAV and HEV were detected by real-time reverse transcription polymerase chain reaction (RT-PCR) according to the ISO/TS 15216 method. HAV was detected in 46.15% of analyzed samples. Conversely, HEV was not detected in any sample. Moreover, the HAV detection rate was significantly associated with seasonal rainfall variations. This qualitative study on HAV and HEV contamination highlights the interest of studying mussel samples from wild areas. As HAV presence in mussels represents a potential health risk, viral contamination surveillance of mussels is necessary to protect consumers. HAV shellfish contamination must be monitored at Cherrat estuary because of the role played by shellfish as HAV reservoirs and/or vehicles in fecal-oral HAV transmission.

In-Silico Exploration of Plant Metabolites as Potential Remedies of Norovirus

Research is still being carried out to develop specific medications or vaccinations to fight norovirus, a key contributor to foodborne illness. This study evaluated certain plant-based active chemicals as prospective candidates for such treatments using virtual screening techniques and other computer assessments. Twenty (20) plant metabolites were tested against the norovirus VP1, VP2, P48, and P22 protein domains using the molecular docking method. In terms of the lowest global binding energy, Asiatic acid, avicularin, guaijaverin, and curcumin exhibited the highest binding affinity with all selected proteins. Each viral protein’s essential binding sites with the potential drugs and drug surface hotspots were uncovered. The ADMET (absorption, distribution, metabolism, excretion, and toxicity) analysis was used to further analyze the pharmacological profiles of the top candidates. According to the results, none of the substances showed any adverse consequences that would reduce their drug-like properties. According to the analysis of the toxicity pattern, no detectable tumorigenic, mutagenic, irritating, or reproductive effects of the compounds were discovered. However, among the top four alternatives, curcumin exhibited the highest levels of cytotoxicity and immunotoxicity. These discoveries may open the way for the development of effective norovirus therapies and safety measures. Due to the positive outcomes, we strongly propose more in vivo experiments for the experimental validation of our findings.
