Analysis of social and psychological factors influencing the treatment of patients with chronic kidney disease under the regular epidemic prevention and control of coronavirus disease 2019.

Objective To explore the sociodemographic and psychological factors influencing the continuity of treatment of patients with chronic kidney disease under the regular epidemic prevention and control of coronavirus disease 2019 (COVID-19). Methods A total of 277 patients with chronic kidney disease who were admitted to Department of Nephrology, The First Affiliated Hospital of Naval Medical University (Second Military Medical University) from Apr. 2020 to Mar. 2021 were enrolled and divided into 3 groups: non-dialysis group (n=102), hemodialysis (HD) group (n=108), and peritoneal dialysis (PD) group (n=67). All patients were investigated by online and offline questionnaires, including self-designed basic situation questionnaire, self-rating anxiety scale (SAS), and self-rating depression scale (SDS). The general sociodemographic data, anxiety and depression of the 3 groups were compared, and the influence of sociodemographic and psychological factors on the interruption or delay of treatment was analyzed by binary logistic regression model. Results There were significant differences in age distribution, marital status, occupation, medical insurance type, caregiver type, whether there was an urgent need for hospitalization and whether treatment was delayed or interrupted among the 3 groups (all P0.05). The average SAS score of 65 PD patients was 38.15+/-15.83, including 53 (81.5%) patients without anxiety, 7 (10.8%) patients with mild anxiety, and 5 (7.7%) patients with moderate to severe anxiety. The average SAS score of 104 patients in the HD group was 36.86+/-14.03, including 81 (77.9%) patients without anxiety, 18 (17.3%) patients with mild anxiety, and 5 (4.8%) patients with moderate to severe anxiety. There were no significant differences in the mean score of SAS or anxiety severity grading between the 2 groups (both P0.05). The mean SDS scores of 65 PD patients were 53.42+/-13.30, including 22 (33.8%) patients without depression, 21 (32.3%) patients with mild depression, and 22 (33.8%) patients with moderate to severe depression. The mean SDS scores of 104 patients in the HD group were 50.79+/-10.76, including 36 (34.6%) patients without depression, 56 (53.8%) patients with mild depression, and 12 (11.6%) patients with moderate to severe depression. There were no significant differences in mean SDS scores or depression severity grading between the 2 groups (both P0.05). The results of intra-group comparison showed that the incidence and severity of depression were higher than those of anxiety in both groups. Multivariate binary logistic regression analysis showed that high school education level (odds ratio OR=5.618, 95% confidence interval CI) 2.136-14.776, P0.01), and unmarried (OR=6.916, 95% CI 1.441-33.185, P=0.016), divorced (OR= 5.588, 95% CI 1.442-21.664, P=0.013), urgent need for hospitalization (OR=8.655, 95% CI 3.847-19.476, P0.01) could positively promote the continuity of treatment in maintenance dialysis patients under the regular epidemic prevention and control of COVID-19. In the non-dialysis group, no sociodemographic and psychological factors were found to be associated with the interruption or delay of treatment (P0.05). Conclusion Education, marital status, and urgent need for hospitalization are correlated with the continuity of treatment in patients with chronic kidney disease on maintenance dialysis.Copyright © 2022, Second Military Medical University Press.

COVID-19 Vaccine: Knowledge and Acceptance among Obstetric Population in Garhwal Region of Uttarakhand

Background: Coronavirus disease-2019 (COVID-19) poses expectant mothers to a higher risk of serious complications and mortality. Following a risk-benefit review, a number of governmental and professional bodies from across the globe recently approved the COVID-19 vaccination during pregnancy. Aim(s): This study aimed to investigate knowledge, actual acceptance, and concerns about the COVID-19 vaccine among the obstetric population. Material(s) and Method(s): Participants were selected from among the expecting women who came for antenatal checkup during the study period (October 1, 2021-November 30, 2021). About 150 pregnant women who met the inclusion criteria and consented were recruited into the study. Data related to socio-demographic and clinical characteristics as well as knowledge, actual acceptance, and concerns about COVID-19 vaccine were collected through in-person interviews using a prestructured questionnaire. The SPSS version 23 was used to analyze data. The association between the attitude (acceptance and hesitance) of participants toward the COVID-19 vaccine and their sociodemographic and clinical profile was found by Fisher's exact test. Result(s): The actual acceptance of the COVID-19 vaccine among expecting women was 52.0%. The primary motive for accepting COVID-19 immunization was to protect the fetus, followed by the protection of one's own health. A significant association was found between COVID-19 vaccine acceptance and the level of education, socio-economic status, and presence of comorbidities. The leading causes for vaccine reluctance were concerns about the efficacy and safety of the vaccines and lack of awareness about their usage during pregnancy. Conclusion(s): Multifaceted activities are required to promote the effectiveness and safety profile of the COVID-19 vaccine as well as disseminate knowledge about its usage during pregnancy. Clinical significance: Unlike numerous other studies that have investigated the accepting attitude only, the present one has investigated the actual COVID-19 vaccine uptake among the obstetric population.Copyright © The Author(s).

Analysis of approaches to sterility testing of COVID-19 prevention vaccines.

Preventive vaccination against SARS-CoV-2 infection is currently receiving close attention in the Russian Federation. Improving public confidence in immunisation with new vaccines largely depends on a guarantee of the absence of side effects caused by contamination. A high risk of contamination is inherent to biological products, including coronavirus prevention vaccines, due to their properties and the nature of raw materials used. This risk adds to the need for using effective contaminant detection approaches. The aim of the study was to evaluate the possibility to improve sterility testing of preventive vaccines against SARS-CoV-2 infection. This article presents an analysis of the procedures proposed by pharmaceutical developers for sterility testing of ten Russian vaccines approved in the country for COVID-19 prevention. The authors considered specific characteristics of these vaccines, including their physical and chemical properties, the presence of antimicrobial components, and other critical factors affecting the correctness of the experimental setup. The results suggest that it is possible to improve sterility testing. According to the authors, the main directions for its improvement are the proposal to develop an alternative procedure based on compendial method 2 (OFS.1.2.4.0003.15, Ph. Rus. XIV), as well as the use of a universal culture medium. If used for refining the established procedures and developing new ones, the authors' recommendations will improve the reliability and applicability of sterility testing during both manufacturing and pre-approval regulatory assessment of updated coronavirus vaccines for subsequent release to the market. The proposed approaches can be applied to testing other medicinal products for sterility.Copyright © 2023 National Electronic-Information Consortium (NEICON). All rights reserved.

Experiences of adult epilepsy patients with COVID-19 infections and vaccinations

Objective: To assess the course of COVID-19 infections and the tolerability of the mRNA vaccines of Moderna and Pfizer/BioNTech and the viral vector vaccines from Astra Zeneca and Johnson & Johnson in adult patients with epilepsy (PWE). Method(s): From July 2020 to July 2021, we consecutively included adult outpatients with confirmed epilepsy. These PWE were interviewed about COVID-19 infections and vaccinations. Results of follow-up visits were added until the cut-off date (December 31, 2021). The data of COVID-19-infected without vaccinations or fully vaccinated PWE without COVID-19 infections were analyzed. Full vaccination was defined as a double vaccination with the Pfizer/BionTech, Moderna, or Astra Zeneca vaccines or a single Johnson & Johnson vaccination. Result(s): At cut-off, 612 of 1152 PWE fulfilled the inclusion criteria: 51 PWE had been infected without vaccination and 561 had full vaccination without infection. Among the infected PWE, 76.5% presented with symptoms;9.8% had a severe course (one death). The leading symptoms were influenza-like disorders (48.7% of infected PWE with symptoms), anosmia (28.2%), and ageusia (20.5%). Seizure increases or relapses after sustained seizure freedom occurred in 7.8%. Adverse events (AEs) were reported by 113 vaccinated PWE (20.1% of all vaccinated PWE). The leading AEs were fatigue, fever, and headache. The AE rate per vaccine was 14.0% for Pfizer/BionTech, 32.7% for Moderna, 25.8% for Astra Zeneca, and 46.2% for Johnson & Johnson. Of the AEs, 93.3% lasted <=1 week. Seizure increase or relapse occurred in 1.4% and was significantly less frequent than in the infected group (p= 0.0016). Conclusion(s): The course of COVID-19 infections and the tolerability of the vaccines were similar as in the general population, yet, seizure worsening occurred more often after the infection than after the vaccination.Copyright © 2023, The Author(s), under exclusive licence to Springer Medizin Verlag GmbH, part of Springer Nature.

A case of possible drug-induced liver injury due to COVID-19 vaccine.

The patient presented with nausea, appetite loss, and fatigue. She had received two doses of Pfizer/BioN-Tech BNT162b2 mRNA vaccine (COMIRNATY) for coronavirus disease 2019 (COVID-19). Acute liver injury was noted 14 days after the first dose of the vaccine. Re-exposure through the second dose worsened the liver injury. After liver biopsy on the third day of admission, methylprednisolone (1000 mg) was administered. Liver histology showed acute hepatitis with diffuse lobular inflammation/necrosis and lymphocyte-dominant infiltra-tion in the portal areas. The patient was diagnosed with drug-induced liver injury due to the COVID-19 vaccine based on the Digestive Disease Week Japan 2004 (DDW-J) scale, which assesses the temporal relationship, liver biopsy, and laboratory findings. With improvements in the blood test parameters, prednisolone was gradually tapered and stopped. One month later, no biochemical signs of relapse were noted. To our knowledge, this is the first report describing liver injury after the administration of the Pfizer COVID-19 vaccine in Japan.Copyright © 2022 The Japan Society of Hepatology.

Uptake of vaccination in older Indian patients with cancer: A cross-sectional observational study

Background: Older patients with cancer are at a higher risk of invasive infections. Vaccination is an effective approach to decrease the mortality and morbidity associated with infections. Objective(s): Our primary objective was to evaluate the proportion of older patients with cancer who had received routine vaccinations against pneumococcal, influenza, and coronavirus disease 2019 (COVID-19). Our secondary objective was to identify the factors associated with vaccine uptake such as age, sex, education, marital status, comorbidities, and place of residence. Material(s) and Method(s): This cross-sectional observational study was conducted in the geriatric oncology outpatient clinic of the Department of Medical Oncology at the Tata Memorial Hospital, a tertiary care cancer hospital in Mumbai, India, from February 2020 to January 2023. We included all patients aged >=60 years who were evaluated in the geriatric oncology clinic during the study period and for whom the immunization details were available. The uptake of COVID-19 vaccine was calculated from March 2021 onwards, which was when the COVID-19 vaccine became available to patients aged >=60 years in India. Result(s): We enrolled 1762 patients;1342 (76.2%) were male. The mean age was 68.4 (SD, 5.8) years;795 (45%) patients were from the west zone of India. Only 12 (0.68%) patients had received the pneumococcal vaccine, and 13 (0.7%) had received the influenza vaccine. At least one dose of the COVID-19 vaccine had been taken by 1302 of 1562 patients (83.3%). On univariate logistic regression, education, marital status, geographic zone of residence, and primary tumor site were correlated with the uptake of COVID-19 vaccine. Factors associated with a greater COVID-19 vaccine uptake included education (up to Std 10 and higher vs. less than Std 10: Odds Ratio [OR], 1.46;95% confidence interval [CI], 1.07-1.99;P = 0.018, and illiterate vs. less than Std 10: OR, 0.70;95% CI, 0.50-0.99;P = 0.041), marital status (unmarried vs. married: OR, 0.27;95% CI, 0.08-1.08;P = 0.046, and widow/widower vs. married: OR, 0.67;95% CI, 0.48-0.94;P = 0.017), lung and gastrointestinal vs. head-and-neck primary tumors (lung cancer vs. head-and-neck cancer: OR, 1.60;95% CI, 1.02-2.47;P = 0.038, and gastrointestinal vs.head-and-neck cancer: OR, 2.18;95% CI, 1.37-3.42;P < 0.001), and place of residence (west zone vs. central India: OR, 0.34;95% CI, 0.13-0.75;P = 0.015). Conclusion(s): Fewer than 1 in 100 older Indian patients with cancer receive routine immunization with influenza and pneumococcal vaccines. Hearteningly, the uptake of COVID-19 vaccination in older Indian patients with cancer is over 80%, possibly due to the global recognition of its importance during the pandemic. Similar measures as those used to increase the uptake of COVID-19 vaccines during the pandemic may be beneficial to increase the uptake of routine vaccinations.Copyright © 2023 Cancer Research, Statistics, and Treatment.

Should Young Covid-19 Patients be Suplemented with Vitamin D?

It is well known that vitamin D's general immunomodulatory actions are helpful in viral infections and that a shortage is linked to a more serious prognosis for Covid-19. In this sistematic review, we examined the existing literature on evidence as to whether there is also link between vitamin D range levels in pediatric population and the outcome of the Covid-19 infection. We looked for studies that measured vitamin D blood concentrations and examined the effects of vitamin D supplementation in young infected patients. Vitamin D may decrease the risk of respiratory infections in a number of ways through its interactions with numerous cells, including by decreasing viral survival and replication, reducing the cytokine storm, raising angiotensin-converting enzyme 2 concentrations (ACE2) while not damaging the endothelial integrity. The incidence or severity of Covid-19 is linked with blood 25-hydroxyvitamin D concentrations, according to many observational studies. However experimental verification is still needed. Given their safety and broad therapeutic window, vitamin D supplements seem to be an effective way for individuals and doctors to prevent or treat Covid-19. Nonetheless, the outcomes of significant vitamin D randomized controlled trials are further needed.Copyright © 2022 Maria Nicolae et al., published by Sciendo.

COVID-19 Vaccination Hesitancy Among 5-11-year-old Iranian Children's Parents: What Are Underlying Beliefs?

Background: Of all teenage deaths caused by coronavirus disease 2019 (COVID-19), 47% occurred in children aged 0-9. Like many other infectious diseases, reducing mortality in children requires widespread vaccination. Despite the availability of the COVID-19 vaccine, a large percentage of children have not received the vaccine. Objective(s): This survey aimed to study parents' reluctance to receive the COVID-19 vaccine for their children in Shiraz, Iran. Method(s): An online questionnaire was sent to parents whose 5 to 11-year-old children had received no COVID-9 vaccine through the health educators of primary schools in Shiraz, Iran. The questionnaire contained demographic questions and 16 beliefs about COVID-19 vaccination that were answered as yes/no. Result(s): We assessed 1093 respondents, including 49.5% (n = 542) male and 50.5% female students' parents. The mean number of wrong beliefs was 7.21 +/- 2.80 in parents who had boys and 7.78 +/- 2.95 in girls' parents. Also, 78.6% of participants had at least five wrong beliefs or excuses for not vaccinating their children. Notably, 82.8% of mothers and 84.3% of fathers were vaccinated with 2-3 doses against COVID-19. The most common wrong beliefs were probable vaccines' side effects in the future, the undesirable effect of vaccination on children's growth, and the awful effect of the vaccine on fertility, with a prevalence of 82.7%, 81.2%, and 76.7%, respectively. Conclusion(s): This study identified that most participants believed that COVID-19 vaccines have side effects for their children and unfavorable effects on children's growth and infertility.Copyright © 2023, Author(s).

Allergic reactions of COVID-19 vaccine based on mRNA-LNP and its pharmacokinetics in vivo.

Vaccination has been proved to be the most effective strategy to prevent the Corona Virus Disease 2019 (COVID-19). The mRNA vaccine based on nano drug delivery system (NDDS) - lipid nanoparticles (LNP) has been widely used because of its high effectiveness and safety. Although there have been reports of severe allergic reactions caused by mRNA-LNP vaccines, the mechanism and components of anaphylaxis have not been completely clarified yet. This review focuses on two mRNA-LNP vaccines, BNT162b2 and mRNA-1273. After summarizing the structural characteristics, potential allergens, possible allergic reaction mechanism, and pharmacokinetics of mRNA and LNP in vivo, this article then reviews the evaluation methods for patients with allergic history, as well as the regulations of different countries and regions on people who should not be vaccinated, in order to promote more safe injection of vaccines. LNP has become a recognized highly customizable nucleic acid delivery vector, which not only shows its value in mRNA vaccines, but also has great potential in treating rare diseases, cancers and other broad fields in the future. At the moment when mRNA-LNP vaccines open a new era of nano medicine, it is expected to provide some inspiration for safety research in the process of research, development and evaluation of more nano delivery drugs, and promote more nano drugs successfully to market.Copyright © 2023, Chinese Pharmaceutical Association.

IN-HOSPITAL CLINICAL COURSE, OUTCOME AND COMPLICATIONS AMONG PATIENTS VACCINATED AGAINST COVID-19.

This retrospective case-series analysis evaluated 403 fully vaccinated with Vero Cell or Sputnik V vaccines patients hospitalized in the 6th City Clinical Hospital of Minsk in the period between January 01 and February 28, 2022 with the main diagnosis of "coronavirus infection (COVID-19)". The diagnosis was confirmed by PCR or SARS-CoV-2 virus antigen tests, as well as chest computed tomography data. The study revealed higher prevalence of older patients (over 65 years) infected with the SARS-CoV-2 virus and hospitalized in early 2022, at the height of the wave of the pandemic due to the spread of the Omicron variant. Most patients (91.8 %) had moderate symptoms. More than half of them received oxygen support. A relatively small number of inpatient, only 8 persons (1.9 %), were hospitalized in the intensive care unit (ICU) and four of them needed mechanical ventilation. Comor-bid conditions and high incidence of mortality (63.5 %) were common in ICU patients. Hypertension and obesity prevailed in the structure of comorbid pathology of all inpatient persons (74.2 and 24.3 %, respectively). Patients of therapeutic departments had relatively short length of stay in the hospital, as well as low in-hospital mortality (0.5 %) and low incidence of complications (5.3 %).Copyright © 2023 The authors.

Appropriate information provision about covid-19 and sars-cov-2 vaccine improves vaccination anxiety in patients with autoimmune liver disease.

The coronavirus disease 2019 (COVID-19) rapidly spread worldwide. Although several vaccines have been developed to control the spread of the disease, the safety and efficacy of the vaccine to patients with autoimmune liver disease are uncertain. However, subjects need to decide whether to receive the vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This study found that 29 of 40 patients with autoimmune liver disease experienced anxiety to receive the SARS-CoV-2 vaccine. After providing information about COVID-19 and the vaccines, the number of patients with vaccination anxiety was reduced from 40 to 14 (p=0.000685). Appropriate provision of the information of COVID-19 and the vaccine improved vaccine anxiety in patients with autoimmune liver disease.Copyright © 2021 The Japan Society of Hepatology.

Pathological findings in semen analysis from COVID-19 survivors and the impact of various SARS-COV-2 vaccines on spermatogenesis.

Male reproductive health depends on many factors, including whether infectious diseases occur in the reproductive system. Such changes may be reflected in the semen analysis. In the past three years, the number of individuals who fell ill with COVID-19 caused by SARS-CoV-2 has been growing worldwide, including in Russia. This infection causes dysfunction and a negative effect on many organs and systems, including reproductive organs, which is reflected in abnormal semen parameters. Despite the high efficacy and small number of side effects found in clinical trials, only 56% of the population in the US and 49% in the Russian Federation reported wanting the vaccine. One of the reasons for distrust of vaccines is the potential negative impact on fertility. A literature review is devoted to the study of the effect of SARS-CoV-2 and vaccination on male reproductive health. The search was carried out using Medline, PubMed, and EMBASE databases.Copyright © 2023 Authors. All rights reserved.

Preventive Measures and Spread of COVID-19 Infection among Dental students in Basra in the First Period of the Epidemic in Iraq: An Online Cross-Sectional Survey

This study was undertaken in the college of the Dentistry-University of Basra, Oral and maxillofacial surgery Department. This survey assessed protective measures regarding COVID-19 infection and aimed to evaluation the evidence on the affiliation between use of preventive measures and COVID-19 infection among dental students in Basra. The questionnaires were designed and assembled into two domains as follows: 1-Personal data including age, sex, and academic stage. 2-Analytical data including questions regarding infection rate among dental students and their commitment of COVID-19 preventive measures. An explanation for the aim of this study was coupled to the questionnaire, and the members were asked to sign an online informed permission. The questionnaires were directed toward 1000 dental students and only 875 were responding to the survey and included in the databank. The duration of study approximately takes 10 days, the questionnaire was conducted to students on February, 12th 2020 and the documents collecting were closed at (February, 22nd 2020). On the topic of preventive measures follow in order to avoid the dispersion of COVID-19 infection, an endemic feature of Corona virus disease has led to the deaths of thousands of individuals across several countries. For the prevention of the extent of the disease and its mortality, several preventive measures have been recommended. Conversely, the level of acquaintance and the implementation of such protective measures against COVID-19 among dental students in Basra which constitute vulnerable group are yet to be evaluated. Eight-hundred and seventy-fife questionnaires were analysed. Out of the 875 participants, (250) were males, and (675) were females. Two hundred and sixty-one (29.8%) participants had been infected with covid-19, and six hundred and fourteen (70%) were not being infected. Regarding the correlation between the infection with COVID-19 and the sex and college stage, consequently, no substantial statistical differences were detected between the males and females amongst COVID infected students. This survey demonstrated that the terms of self-protective means in addition to community disaffection will be considerably drops the statistics of dental student's COVID infections.Copyright © RJPT.

Scientific rationale of Indian AYUSH Ministry advisory for COVID-19 prevention, prophylaxis, and immunomodulation

The current outbreak of COVID-19 is caused by the SARS-CoV-2 virus that has affected > 210 countries. Various steps are taken by different countries to tackle the current war-like health situation. In India, the Ministry of AYUSH released a self-care advisory for immunomodulation measures during the COVID-19 and this review article discusses the detailed scientific rationale associated with this advisory. Authors have spotted and presented in-depth insight of advisory in terms of immunomodulatory, antiviral, antibacterial, co-morbidity associated actions, and their probable mechanism of action. Immunomodulatory actions of advised herbs with no significant adverse drug reaction/toxicity strongly support the extension of advisory for COVID-19 prevention, prophylaxis, mitigations, and rehabilitation capacities. This advisory also emphasized Dhyana (meditation) and Yogasanas as a holistic approach in enhancing immunity, mental health, and quality of life. The present review may open-up new meadows for research and can provide better conceptual leads for future researches in immunomodulation, antiviral-development, psychoneuroimmunology, especially for COVID-19.Copyright © 2021, Institute of Korean Medicine, Kyung Hee University.
