RESUMO

Objective: The current study aimed to describe the clinical characteristics of mild SARS-CoV-2 infected pregnant women with abnormal liver function (ALF), explore the association between ALF with maternal and fetal outcomes. Method(s): This retrospective analysis included 87 pregnant patients with mild SARS-CoV-2 infection admitted and treated from December 1, 2022, to 31, 2022 in the department of Obestircs at Beijing Obstetrics and Gynecology Hospital. We evaluated patients for demographic and clinical features, laboratory parameters and pregnancy complications. Result(s): 27 Patients in this cohort had clinical presentations of ALF. Compared with the control group, the peripheral blood platelet (PLT), D-dimer quantitative determination (D-Dimer), lactate dehydrogenase (LDH), total protein (TP), albumin (ALB), indirect bilirubin (DBIL), gamma- glutamyltranspeptidase (GGT) and total bile acid (TBA) showed significantly differences (p<0.05). 12 cases (44.44%) complicated with pregnancy induced hypertension (PIH), 14 cases (51.85%) complicated with intrahepatic cholestasis of pregnancy (ICP), 2 cases (7.4%) complicated with acute fatty liver during pregnancy (AFLP) and 5 cases (14.81%) complicated with postpartum hemorrhage in patients with abnormal LFT were significantly higher than those in the control group (p<0.05). Compared with the control group, the incidence of premature delivery (22.22%) and fetal distress (37.04%) in the experiment group were significantly higher (p<0.05), and the incidence of neonatal asphyxia was not significantly different (p>0.05). Conclusion(s): Pregnant women are generally susceptible to mild SARS-CoV-2 and may induce ALF. ALF is associated with increased risk of mother and infant. The maternal and infant outcomes of those who terminated pregnancy in time are acceptable. Therefore, pregnant women with COVID-19 who received antiviral treatment should be closely monitored for evaluating liver function and relevant indicators. The long-term outcomes in the future are worth to further study.Copyright © 2023

RESUMO

Objective To investigate the impact of dynamic adaptive teaching model on surgical education. Methods Due to the COVID-19 pandemic in 2020, we adopted dynamic adaptive teaching model in the Department of Breast Surgery, Peking Union Medical College Hospital, which divided the whole curriculum into several individual modules and recombined different modules to accommodate to student's levels and schedules. Meanwhile, adaptive strategy also increased the proportion of online teaching and fully utilized electronic medical resources. The present study included quantitative teaching score (QTS) recorded from January 2020 to June 2020, and used the corresponding data from 2019 as control. The main endpoint was to explore the impact of dynamic adaptive teaching model on overall QTS and its interaction effect with trainer's experience and student category. Results Totally, 20 trainers and 181 trainees were enrolled in the present study. With implementation of dynamic adaptive strategy, the overall QTS decreased dramatically (1.76+/-0.84 vs. 4.91+/-1.15, t=4.85, P=0.005). The impact was consistent irrespective of trainers' experience (high experience trainers: 0.85+/-0.40 vs. 2.12+/-0.44, t=4.98, P=0.004;medium experience trainers: 0.85+/-0.29 vs. 2.06+/-0.53, t=4.51, P=0.006;and low experience trainers: 0.10+/-0.16 vs. 0.44+/-0.22, t=2.62, P=0.047). For resident (including graduate) and undergraduate student teaching, both QTS was lower with dynamic strategy (residents: 0.18+/-0.34 vs. 0.97+/-0.14, t=4.35, P=0.007;undergraduate students 1.57+/-0.55 vs. 3.77+/-1.24, t=3.62, P=0.015), but dynamic strategy was effective for post-doc student subgroup and reached comparable QTS as traditional model (0.00+/-0.00 vs. 0.17+/-0.41, t=1.00, P=0.363). Conclusions Dynamic adaptive teaching strategy could be a useful alternative to traditional teaching model for post-doc students. It could be a novel effective solution for saving teaching resources and providing individualized surgical teaching modality.Copyright © 2023, Peking Union Medical College Hospital.

RESUMO

Aims The study aimed to examine the nature and outcomes of social support for the well-being and quality of life (QoL) of adults with epilepsy. Methods The Australian Epilepsy Longitudinal Survey's 5 th Wave included the Medical Outcomes Study Modified Social Support Survey on four dimensions of social support and the QOLIE-31. Both numerical data and open-ended responses were analyzed quantitatively and qualitatively. A mixed method was used where quantitative analysis used t -tests, analysis of variance and block recursive regression, and qualitative analysis identified themes. Results Three-hundred thirty-two people with epilepsy (PWE) participated. The quantitative component showed that for emotional/informational support being older and living alone were key factors. These as well as household income were important in tangible support. For affectionate support living alone and household income were factors, but only income was a factor for positive social interaction. In addition, only positive social interaction predicted increased QoL. In the qualitative component of the study both positive and negative supports were identified for the emotional/informational supports. Many reported the benefits of having information, although some reported failure to have their needs taken seriously by health professionals or epilepsy associations. Inability to drive was an important feature of negative tangible support as was finding some assistive services unaffordable. Reports of positive social interaction identified being accepted as a person with epilepsy that is the primary concern. Peer support plays a role here. Discussion The findings of factors affecting the four dimensions of support in this study have supported a number of studies. This includes the effects of positive social interaction on QoL. The qualitative analysis supports these results, but it also contributes to deeper understanding of support in the lives of PWE. Conclusion Social support is a particularly important issue for PWE. The results of this study demonstrate the complexities and benefits of obtaining the appropriate forms of support. This survey took place before the coronavirus disease 2019 pandemic and it may well be that this phenomenon affects PWE's support needs. Copyright © 2023. Indian Epilepsy Society.

RESUMO

PurposeThis study evaluates the impact of online menus and perceived convenience of online food ordering on consumer purchase intention and shows how a desire for food creates a relationship between an online menu and a customer's purchase intention. Suggestions for management are proposed to design an effective menu to improve business performance in the competitive market in Vietnam.Design/methodology/approachThe paper follows a quantitative method. Quantitative research aims to analyze and critically evaluate the research question(s) to discover new factors.FindingsFindings indicate a positive relationship between menu visual appeal (MV), menu informativeness (MI), desire for food (DF), the perceived convenience (PC) of ordering food online and intention to purchase (PI). The attractiveness of images and information is a significant factor affecting diners' desire to eat, while the demand for food and the convenience of ordering food online are also factors affecting purchase intention.Practical implicationsThe study confirms the importance of online menus to purchase intention. Economically, when supply and demand are reasonable, the market is stable and technology develops. In terms of social, hygiene, attractiveness and price factors, it is helpful to have an overview. Research is the premise for further studies with factors from menu to customer trust.Originality/valueThe study provides a solid foundation for further studies on restaurant menu elements as well as a new perspective on how restaurants improve their dishes.

RESUMO

Self-medication is a widespread public health concern. University students are likely to be more prone to it since self-medication rates increase with educational level. Studies have shown that self-medication rates vary among academics belonging to different faculties, and medical students have the highest self-medication rates. However, it is unknown whether this holds in a vulnerable situation, such as the COVID-19 pandemic. It is also unknown whether differences in technical knowledge of drugs influence self-medication rates among students. Thus, this study analyzes and compares prophylactic self-medication among graduate students of different faculties in the context of the COVID-19 pandemic. This cross-sectional observational study was conducted at a private university in southern Brazil. Students from the medicine, law, life sciences, and fine arts faculties were surveyed, and their responses were compared using a chi-square test. Among 396 respondents, 29.5% reported using preventive medication for COVID-19, and medical students were the least likely to do so. The self-medication rate was 13.6% among respondents, and self-medication did not differ significantly between students of different faculties. Of the students who self-medicated 63% reported having studied the medication before using them. Furthermore, the media did not induce drug use among 81.8% respondents. These results show that medical students used fewer preventive medications during the pandemic and refute the assertion that self-medication rates are higher among medical students. They also show that self-medication rates during the pandemic were significantly lower than those before the pandemic. These revelations show a new aspect of self-medication.Copyright © 2021 Muslim OT et al.

RESUMO

Objectives: The objectives of the study was to assess the level of work satisfaction, assess compliance of using PPE among shop assistants during COVID-19 and to find the factors influencing work satisfaction. Method(s): A quantitative approach with descriptive design was used for the study. Eighty samples were selected by using convenient sampling technique. The study was conducted in 4 districts of Kerala through online platform as well as through offline mediums. Result(s): From the study, it is evident that majority of the subjects (55%) were satisfied with their work at the time of COVID-19 and more than half (55%) of the samples have enough compliance with the use of PPE and only 7.5% have less compliance with the use of PPE. Demographic variables such age, relationship status, and work experience were found to be statically significant (p<0.05) with work satisfaction, and other variables did not have a significant association. Conclusion(s): This study provides a baseline for assessing the level of work satisfaction and compliance of PPE among shop assistants in selected areas. Periodic reinforcements, proper education, availability and trainings on the use of PPE can reduce the spread of Corona Virus and improve PPE compliance to an extend. Good working environment support from family and good rapport with colleagues can help to improve work satisfaction .Copyright © 2023 The Authors.

RESUMO

Background: The pandemic of Covid-19 impeded all socio-economical, pedagogic, and recreational activities. Pakistan is facing an intensified educational crisis due to previous educational differences, so the era of the pandemic has shown difficulties in the educational framework. Aim(s): Awareness among parents and students to combat challenges of pandemic. Method(s): The current study is based on random quantitatively study which gathered data from 300 respondents assembled from different areas of Lahore, Pakistan from June 2020 to July 2021. The responses were collected from students, teachers, and parents that how homeschooling compromises student's physical, psychological, and emotional health. Result(s): About 76% of the students favoured traditional classes over online classes whereas only 20% of the students found the online session interactive. In the other section, only 15.33% of the teachers were satisfied by the online results and they complained about the poor performance and interaction with the students. Overall, 81.67% parents agreed that there is a decline in the physical activity of their children. The results of this study suggested that social distancing and the emerging challenges associated with Covid- 19 have entirely changed the education system that has caused number of problems for children, parents, and teachers in Pakistan. Practical implication: This study highlights pros and cons of online study;such studies give students and teachers a way to prepare for future challenges. Conclusion(s): Considering all outcomes of study, it is highlighted that policy-level interventions were needed, along with well-designed interactive courses. Hence, integrated approaches based on the mental as well as physical capabilities of the students must be executed, and e-tools must also be practiced in traditional classes to fill the gap of homeschooling.Copyright © 2023 Lahore Medical And Dental College.

RESUMO

BACKGROUND: Vaccines are one of the best interventions developed for eradicating COVID-19. In Albania, COVID-19 vaccination uses different types of vaccines: Pfizer, AstraZeneca, CoronaVac, and Sputnik V. Like any other vaccine, these have side effects too. AIM: This study was carried out to identify the perception of the side effects of vaccines. METHOD(S): A quantitative study using a cross-sectional survey was conducted between April and September 2021 to collect data on the effects of the COVID-19 vaccine among individuals in Shkodra region. Data were collected online through a self-administered survey created on Google Forms which had been randomly delivered to individuals (aged >=18 years) using social media sites (Email and WhatsApp). All data collected were analyzed with Microsoft Office Excel 2010, using the exact Fisher's test and x2 test. RESULT(S): This study included 292 citizens, out of which 200 were female and 92 were male;62% were from urban areas and 38% from rural areas of Shkodra region. The random sample of the citizens who took part in this study is 44.5% (18-30 years old). A massive percentage of the participants, 66.4%, had received the second dose of the vaccine. Our study shows that 55.8% of these citizens have had side effects after the first vaccination dose, and only 43.8% have had side effects after the second dose. About 80.6% of the participants were well informed about the type of vaccine they got. CONCLUSION(S): Side effects from vaccines were reported. Injection site pain and fatigue were the most common first dose side effects (55.8%). The same side effects were reported for the second dose. The side effects were presented during the first 12 h after the vaccination in most cases. Side effects were more prevalent in people >50 years old. Older people have a higher probability to have more side effects from the COVID vaccine. There is no statistically significant relationship between gender and the presence of the side effect from the COVID vaccine. People living in urban areas have a higher probability to have side effect from COVID vaccine comparing with people living in rural areas. People being vaccinated with Pfizer vaccine have a higher probability to admit the presence of side effects.Copyright: © 2022 Zamira Shabani, Arketa Guli, Julian Kraja, Arlinda Ramaj, Nertila Podgorica.

RESUMO

Objective: Healthcare professionals were the workers most affected by Covid-19, espe-cially during the first waves of the pandemic. Thus, the aim of this study is to evaluate the perceived risk of exposure to Covid-19, the information received and the work participation between nurses, physicians and nursing assistants. Method(s): A cross-sectional study was conducted using an epidemiological survey among nurses, physicians and nursing assistants in a university hospital. Aspect and content validation, cognitive pretest, and piloting of the epidemiological survey was carried out with thirty subjects. A descriptive analysis was per-formed using mean and standard deviation (SD) for quantitative variables and absolute (n) and relative (%) frequencies for qualitative variables. The chi-square test and the ANOVA test were applied to assess the association of the responses with the variables: sex, type of worker, area of work and activity in Covid-19 Units. Result(s): Nurses, physicians and nursing assistants worked mainly in assistance areas and high risk of exposure units. Nursing assistants and nurses had a higher perception of risk. Nurses were less involved in the organiza-tion, but felt more supported by their colleagues. However, physicians felt more supported by their superiors and better care when they had a health problem. Conclusion(s): Nursing assistants and nurses presented higher risk perception, nurses were less involved in the organization of health care, while physicians felt more supported by their superiors.Copyright © 2023, Fundacion Index.

RESUMO

Problem: COVID-19 placentitis is a rare complication of maternal SARS-CoV-2 respiratory infection associated with serious adverse obstetric outcomes, including intra-uterine death. The precise role of SARS-CoV-2 in COVID-19 placentitis is uncertain, as trophoblast infection is only observed in around one-half of the affected placenta. Method of Study: Through multi-omic spatial profiling, including Nanostring GeoMX digital spatial profiling and Lunaphore COMET multiplex IHC, we provide a deep characterization of the immunopathology of placentitis from obstetrically complicated maternal COVID-19 infection. Result(s):We show that SARS-CoV-2 infection of placental trophoblasts is associated with a distinct innate and adaptive immune cell infiltrate, florid cytokine expression and upregulation of viral restriction factors. Quantitative spatial analyses reveal a unique microenvironment surrounding virus-infected trophoblasts characterizedd by multiple immune evasion mechanisms, including immune checkpoint expression, cytotoxic T-cell exclusion, and interferon blunting. Placental viral loads inversely correlated with the duration of maternal infection consistent with progressive virus clearance, potentially explaining the absence of virus in some cases. Conclusion(s): Our results demonstrate a central role for placental SARS-CoV-2 infection in driving the unique immunopathology of COVID-19 placentitis.

RESUMO

Orygen's role in supporting the Australian Early Psychosis Program AEPP) includes workforce development and training. Aim(s): The aim of this project was to deliver training and to develop and connect a national early psychosis network during the global pandemic which reduced face to face workforce development activity. Method(s): A blended learning approach was adopted, incorporating sharing support resources for clinicians in managing risk online, and developing online training and discussion events. Multi-site workshops and interactive events were developed and delivered providing an avenue of support to clinicians and increasing activity and engagement with the AEPP hub where a range of resources and activities were available. The online AEPP hub was used as a central point for training, online events and other workforce development activity. Conclusion(s): Clinicians from Australia's Early Psychosis program were offered a range of activities across modalities to increase their support, connection, skills and knowledge during a period of time where it became increasingly difficult to share information in face to face settings. Data alongside quantitative information and evaluation was collected to understand if the strategy was successful. A blended interactive learning strategy that incorporates multi-site interactive workshops, online events and an online HUB' has been successful in connecting an early psychosis workforce and increasing engagement with each other via interactive modalities in a world unable to connect face to face. This data collected will be presented.

RESUMO

Introduction: In early 2020, restrictions were established to control the transmission of COVID-19, such as the suspension of elective public health care. Dental teleservice has become an alternative to patient follow-up. In Brazil, the Federal Council of Dentistry published Resolution 226/2020, allowing the performance of dentistry at a distance. Objective(s): To assess dentists' satisfaction with the use of the oral telediagnosis service during the COVID-19 pandemic. Material(s) and Method(s): Cross-sectional and quantitative study. An online questionnaire was released to 636 dentists in the North of Minas Gerais, Brazil, between May and September 2022, with 298 respondents. The database was built using the Statistical Package for the Social Sciences, 24.0 software. This study was approved by the CEP (#5.267.570). Result(s): There was a predominance of dentists working in the public health network (86.2%;n=257). Most profession-als reported a drop in face-to-face calls during the pandemic (94.2%;n=281), and 86.2% (n=257) had losses from their activities. Teleservice resources were used during social isolation by 75.8% (n=226) of dentists, mainly for patient follow-up (63.7%;n=190). Consultation by phone was the main virtual method (63.7%;n=190). Regarding teleservice, 58.6% (n=119) of dentists realized the system was easy to use, and 50.2% (n=101) would like to continue using it after the pandemic. Conclusion(s): This is the first Brazilian study to assess dentists' satisfaction with teleservice. It is concluded that teleservice can contribute to early diagnosis and assistance by professional users.

RESUMO

Objectives: The public's stated preference for public health and social measures (PHSMs), and levels of pandemic fatigue are insufficiently fixed. We aim to quantify the public's preferences for varied PHSMs, and measure population's pandemic fatigue. Method(s): We conducted a cross-sectional, nationwide sampling, survey-based experiment to assess public preference for and attitudes towards PHSMs. A set of psychometric scales, specifically, the COVID-19 pandemic fatigue scale (CPFS), was used to screen fatigue levels in the respondents. The multinomial logit model (MNL) and latent class model (LCM) were utilized for choice tasks analysis, and Mann-Whitney tests were used for CPFS statistical analysis. Result(s): There were 689 respondents, who completed the survey, and were included in the study after quality control. The discrete choice experiments revealed that respondents attached the greatest importance to the risk of COVID-19 infection within three months (45.53%), followed by loss of income within three months (30.69%). Vulnerable populations (lower-income and older respondents) are more sensitive to the risk of infection, and younger respondents are more sensitive to income loss and prefer non-suspension of socialization and transportation. Migrants, and respondents with a higher level of fatigue, have less acceptance of the mandatory booster vaccination and suspension of transportation. Additionally, a higher fatigue level was observed in females, younger respondents, migrants, and relatively lower-income respondents. Conclusion(s): Fatigue and fear of COVID-19 infection contributed to the public's mental health problem. Hence, at the late-stage pandemic, policymakers should consider reducing people's mental burden via relieving people's fear of infection when PHSMs are being relaxed. And this also provides insights for the outbreaks' PHSMs implementation in the future.Copyright © 2023

RESUMO

Background: The Covid-19 pandemic radically changed the way of studying, suddenly we went from fa-ce-to-face learning to a virtual one, in many cases without digital media, without properly managing plat-forms, adding anxiety to contagion, fear of death, economic instability, the uncertainty that it will happen, brings with it changes in academic work, thus influencing academic performance. Aim(s): Relate anxiety, self-esteem and study habits with academic performance in Peruvian university students. Methos: Quantitative, longitudinal, correlational and prospective study with a non-probabilistic sample of 260 students from the 1st cycle of the USS period 2020-II, virtual questionnaires were applied to measure anxiety (Beck's Anxiety Inventory), self-esteem (Stanley's Self-esteem Inventory Coopersmith), study habits (CASM-85 Study Habits Inventory) and academic performance (Promotional Proceedings). Result(s): 40% of the students present a minimum level of anxiety, 50.4% present high average self-esteem and 25.8% have very positive study habits. Conclusion(s): There is a relationship between anxiety and academic performance with statistical significan-ce;while self-esteem, study habits and academic performance were not statistically significant.Copyright © 2023, Ediciones Avances S.L..

RESUMO

Problem: Although it is rare for a SARS-CoV-2 infection to transmit vertically to the fetus during pregnancy, there is a significantly increased risk of adverse pregnancy outcomes due to maternalCOVID- 19. However, there is a poor understanding of such risks because mechanistic studies on how SARS-CoV-2 infection disrupts placental homeostasis are significantly lacking. The SARS-CoV-2 proteome includes multiple structural and non-structural proteins, including the non-structural accessory proteinORF3a. The roles of these proteins in mediating placental infection remain undefined. We and others have shown that autophagy activity in placental syncytium is essential for barrier function and integrity. Here, we have used clinical samples and cultured trophoblast cells to evaluate syncytial integrity of placenta exposed to SARS-CoV-2. The objective of our study was to investigate potential mechanisms through which SARS-CoV-2 impairs placental homeostasis and causes adverse pregnancy outcomes. We tested the central hypothesis that an essential SARS-CoV-2 non-structural and accessory protein, ORF3a, uniquely (amongst multiple viral proteins tested) with a novel three-dimensional structure andwith no homology to any other proteins is a key modulator of placental trophoblast cell dynamics via autophagy and intracellular trafficking of a tight junction protein (TJP), ZO-1. Method(s): We used clinical samples and cultured trophoblast cells to evaluate syncytial integrity of placentas exposed to SARS-CoV- 2. Autophagic flux was measured in placental villous biopsies from SARS-CoV-2-exposed and unexposed pregnant women by quantifying the expression of autophagy markers, LC3 and P62. Trophoblast cells (JEG-3, Forskolin-treated JEG-3, HTR8/SVneo, or primary human trophoblasts (PHTs)) were transfected with expression plasmids encoding SARS-CoV-2 proteins including ORF3a. Using western blotting, multi-label immunofluorescence, and confocal imaging, we analyzed the effect of ORF3a on the autophagy, differentiation, invasion, and intracellular trafficking of ZO-1 in trophoblasts. Using coimmunoprecipitation assays, we tested ORF3a interactions with host proteins. t-tests and one-way analyses of variance (ANOVAs) with post hoc tests were used to assess the data, with significance set at P < .05. Result(s): We discovered :1) increased activation of autophagy, but incomplete processing of autophagosome-lysosomal degradation;2) accumulation of protein aggregates in placentas exposed to SARS-CoV- 2. Mechanistically, we showed that the SARS-CoV-2 ORF3a protein, uniquely 3) blocks the autophagy-lysosomal degradation process;4) inhibits maturation of cytotrophoblasts into syncytiotrophoblasts (STBs);5) reduces production ofHCG-beta, a key pregnancy hormone that is also essential for STB maturation;and 6) inhibits trophoblast invasive capacity. Furthermore, ORF3a harbors an intrinsically disordered C-terminus withPDZ-bindingmotifs.We show for the first time that, 7) ORF3a binds to and co-localizes with the PDZ domain of ZO-1, a junctional protein that is essential for STB maturation and the integrity of the placental barrier. Conclusion(s): Our work outlines a new molecular and cellular mechanism involving the SARS-CoV-2 accessory protein ORF3a that may drive the virus's ability to infect the placenta and damage placental syncytial integrity. This implies that the mechanisms facilitating viral maturation, such as the interaction of ORF3a with host factors, can be investigated for additional functionality and even targeted for developing new intervention strategies for treatment or prevention of SARS-CoV-2 infection at the maternal-fetal interface.

RESUMO

Background: The prevalence of emerging and re-emerging diseases has made the need for basic preparations for all health care organizations more crucial. Strengthening preparedness and formulating crisis strategies will have a great impact on reducing casualties. Given the importance of preparing hospitals to deal with such an outbreak and reduce the resulting mortality, the present study was conducted to assess their readiness against Covid-19. Method(s): The present study is a quantitative and descriptive cross-sectional research conducted from October to March 2019. Data collection used the standard checklists prepared by the European Center for the Prevention and Control of Coronavirus and the Centers for Disease Control and Prevention, consisting of eight domains and 21 components. The minimum score that each hospital could get in this checklist was 143 and the maximum was 429. The sampling method in the present study was a census, and nine reference hospitals for Corona were included in the study. All hospitals' directors, managers, quality officers and crisis secretaries and others related to hospital readiness during Covid-19 were recruited by the census. Result(s): On average, the hospitals scored 391 out of 429, indicating a fairly "high readiness" in dealing with Covid-19. The highest score obtained by the hospitals was 425 and the lowest score was 349. In terms of preparation areas, the hospitals' readiness was higher than 80% in all areas. The highest readiness of hospitals was in the fifth domain, i.e. Hand hygiene, personal protective equipment and hospital waste management. The 7th domain namely, patient placement and relocation, and patient visitor access was of the lowest preparation. Conclusion(s): The hospitals were of fairly appropriate readiness to deal with Covid-19. This level of preparedness, despite being desirable, might not reflect the real capacity of hospitals to deal with this disease. Regular evaluation of the Covid referral hospitals could help make these hospitals more prepared. Also, the experiences of hospitals that were more prepared should be used to improve the condition of other hospitals.Copyright © 2022 Jaafaripooyan et al.

RESUMO

BACKGROUND: The coronavirus disease 2019 (COVID-2019) causes the severe contagious acute respiratory syndrome. Therefore, massive vaccination campaign is mandatory to control the spread. Sputnik COVID-19 vaccines induce immunity through different mechanisms involving antibody response that bind to the spike protein to neutralize the viral entry into the cells. AIM: This study aims to compare the titers of specific antibodies in the pre-and post-vaccination sera in the vaccinated Egyptian population to evaluate the efficacy of the sputnik vaccine. METHOD(S): Samples were collected from 205 adult volunteers receiving the Sputnik vaccine in the Reference Laboratory of Egyptian University Hospitals. Samples were collected before vaccination and within 1, 2, or 3 months after receiving two doses of Sputnik SARS-CoV-2 vaccines from August to October 2021, serum samples collected were tested by quantitative chemiluminescent immunoassay using (Mindray CL-960i chemiluminescence analyzer, India) at the Reference laboratory of Egyptian University Hospitals for neutralizing antibodies, anti-spike antibodies, and total antibody levels before and after vaccination. RESULT(S): The results of the 205 paired samples illustrated that there was a statistically significant difference between pre-and post-vaccination antibody levels with a p-value of (< 0.001) indicating that the vaccine produced significantly high levels of antibodies. CONCLUSION(S): COVID-19 Sputnik vaccines induce immunity through an antibody response that binds to the virus to neutralize its entry into cells. Our study showed a significant increase in the measured post-vaccination levels of the three antibodies among the enrolled volunteers compared to the basal pre-vaccination level and thus sputnik vaccine protects against SARS-CoV-2 infections.Copyright © 2023 Ghada Ismail, Dalia Abdelhamid, Marwa Salah Mostafa, Noha Alaa Eldin Fahim, Ahmed Elshafei, Hossam Abdelghaffar, Nashwa Naguib, Omnia Taher, Menna Asker.

RESUMO

Introduction: The COVID-19 pandemic has disrupted health care systems worldwide, but the specific impact on pediatric surgery in low-and-middle-income countries has received little attention. This study evaluated the changes in pediatric surgical case volume at a central referral hospital in Malawi from 2019 through 2021 to quantify the impact of COVID-19. Method(s): We retrospectively reviewed all pediatric surgical cases performed at our institution from May-August 2019, 2020, and 2021. These months were chosen because they coincided with the first major wave of COVID cases in Malawi in 2020. We compared the number of cases performed per week between years and analyzed case numbers by specialty (general, orthopedic, plastic, neurosurgery, ENT, and urology). Result(s): A total of 1032 procedures were performed. There was a 32% reduction in case volume between 2019 to 2020 (344 to 235 cases, 19.5 vs 13.8 per week, p=0.04), with a subsequent 93% increase from 2020 to 2021 (235 to 435 cases, 13.8 vs 26.4 per week, p<0.001). The most significantly impacted specialties were ENT and plastics, both with 78% fewer procedures in 2020 compared with 2019, and a subsequent 4-fold and 22-fold increase in cases from 2020 to 2021, respectively (Chi-Square;p=0.007 and p<0.001). Orthopedic and Neurosurgical case numbers were impacted the least, with reductions ranging from 22% to 35%. Conclusion(s): The COVID-19 pandemic significantly reduced the number of pediatric surgical cases performed at the central referral hospital in Malawi across all specialties, thereby further limiting essential surgical services to an already marginalized patient population.
