ABSTRACT
The COVID-19 pandemic situation affected population health and lifestyle not only for a short period but also long period. Long COVID symptoms is a long-term illness after COVID condition. Long COVID symptoms greatly affected to quality of life of patients. Massage is a unique treatment form of alternative medicine that can promote health in various dimensions. From the previous studies, massage has affected to Long COVID mechanism via anti-inflammatory process, immune system enhancing process, and hormone level balancing that related to Long COVID symptoms as well as being able to reduce the symptoms of the long COVID symptoms. The study about the efficacy and safety of massage against Long COVID symptoms is the essential approach to increase the value of massage and develop health services in the future.
ABSTRACT
As an important immuneoactive component in eggs, yolk immunoglobulin (IgY) shows great competitiveness in research and production due to its good stability, high safety, low cost, easy availability, strong immune activity, and no drug resistance. This article highlights the significant advantages of IgY as a good antibiotic substitute in the prevention and treatment of viral and bacterial diseases. Also, IgY has great potential in the regulation of nutrient metabolism balance, intestinal microflora and immune homeostasis by affecting key rate-limiting enzymes, and relevant receptors and inflammatory factors specifically. Proper diet and targeted delivery of foodborne IgY may be a new perspective on inflammation regulation, disease control, nutritional balance or homeostasis, and oral microencapsulated IgY is expected to be a new approach against increasing public health emergencies (such as COVID-19 pandemic).
ABSTRACT
Background. Since the start of the COVID-19 pandemic, Chad has had 7,417 confirmed cases and 193 deaths, one of the lowest in Africa. Objective. This study assessed SARS-CoV-2 immunity in N'Djamena. Methods. In August-October 2021, eleven N'Djamena hospitals collected outpatient data and samples. IgG antibodies against SARSCoV- 2 nucleocapsid protein were identified using ELISA. "Bambino Gesu" Laboratory, Rome, Italy, performed external quality control with chemiluminescence assay. Results. 25-34-year-old (35.2%) made up the largest age group at 31.9 12.6 years. 56.4% were women, 1.3 women/men. The 7th district had 22.5% and the 1st 22.3%. Housewives and students dominated. Overall seroprevalence was 69.5% (95% CI: 67.7-71.3), females 68.2% (65.8-70.5) and males 71.2% (68.6-73.8). >44-year-old had 73.9% seroprevalence. Under-15s were 57.4% positive. Housewives (70.9%), civil servants (71.5%), and health workers (9.7%) had the highest antibody positivity. N'Djamena's 9th district had 73.1% optimism and the 3rd district had 52.5%. Seroprevalences were highest at Good Samaritan Hospital (75.4%) and National General Referral Hospital (74.7%). Conclusion. Our findings indicate a high circulation of SARS-CoV- 2 in N'Djamena, despite low mortality and morbidity after the first two COVID-19 pandemic waves. This high seroprevalence must be considered in Chad's vaccine policy.
ABSTRACT
Background: The severity of COVID-19 infection has an increasing trend in the elderly, which contributes to the high morbidity and mortality rates in this population. Aging itself is a prominent risk factor for severe disease and death from COVID-19. Case Description: This case report a 71-year-old woman who complained of shortness of breath for 3 days before being admitted to the hospital. Bilateral consolidation and increased bronchovascular pattern were found on chest radiograph, and a positive SARS-COV2 nasopharyngeal swab PCR test result was noted. This patient was diagnosed with confirmed severe manifestation of COVID-19, community-acquired pneumonia and type 1 respiratory failure, as well as type II diabetes mellitus and suspicion of acute gastritis. The results of the geriatric status assessment were moderate functional status, risk of malnutrition, and moderate risk of deep vein thrombosis (DVT). This patient underwent treatment in accordance with the COVID-19 protocol along with management for geriatric status improvement. The patient was given permission to return home after 14 days of treatment, during which time her health had improved and her functional status had changed to moderate dependency. During follow-up, the patient continued to receive therapy. She is still being observed and future evaluations will be conducted. Conclusion: The increased susceptibility of the elderly to COVID-19 infection is caused by various factors. A burden of death and long-term disability brought on by this pandemic may be lessened by new or modified therapies that target aging-associated mechanisms. Therefore, COVID-19 case management in this population should be done with a comprehensive approach.
ABSTRACT
Objective: This study included participants from Hacettepe University 4th, 5th, and 6th-grade students of Medical School and 4th and 5th-grade students of Dental School;and aimed to evaluate the general health status, COVID-19 history, vaccination status, and SARS-CoV-2 antibody levels of the participants to support their physical and social health, during the pandemic period. Methods: A prospective cohort study was conducted with an integrated, matched, nested case-control study. Sociodemographic characteristics, life habits, COVID-19 history, vaccination status, compliance with mask-distance-hygiene rules, and risks (if any) for COVID-19 were inquired via online questionnaires. Physical examinations, complete blood count, biochemistry tests, and anti-SARS-CoV-2 anti-spike antibody tests were conducted for all consenting participants. All analyses were established using depersonalized data. Results: Of the 778 participants completing the baseline visit in June-July 2021, the percentages of those vaccinated with at least one, two, and three/more doses of COVID-19 vaccine were 99.1%, 98.0%, and 11.7%, respectively;one had four doses. The median (minimum-maximum) time since the last vaccination was 134 (34-166) days for those vaccinated with two doses [CoronaVac (Sinovac Life Sciences, Beijing, China)] and 25 (14-56) days for those vaccinated with three doses [two doses of CoronaVac and a last dose of Pfizer-BioNTech mRNA vaccine (ComirnatyR). The third dose was applied at a median of 164 (151-202) days after the second dose, and all were heterologous in type. The median (minimum-maximum) antibody level for the overall group was 53.55(0-5680) BAU/mL: 47.19 BAU/mL in those who received two doses, with a more than 100 times increase after a third dose (4943.64 BAU/mL). Of the 522 participants followed up to October 1, 2021, 6 PCR-positive symptomatic participants were diagnosed with COVID-19: the incidence rate was 4/1000 person-months. Conclusion: A 100-fold neutralizing antibody level following the third dose demonstrated the importance of a booster dose. Given the time lag between doses, antibody measurements of BioNTech recipients should be repeated in the upcoming months. Booster selection should involve antibody level, variant sensitivity of the vaccine, and individual characteristics of the recipient.
ABSTRACT
Objective: Vaccines are one of the promising approaches to control the pandemic. The aim of this study, which was conducted on healthcare workers who previously were or were not infected with COVID-19, was to evaluate the undesirable effects that developed after the CoronaVac (Sinovac Life Sciences, Beijing, China). Methods: Volunteers who were administered the first dose of inactivated CoronaVac vaccine between January 14-24, 2021, were included in this retrospective study. Demographic information was obtained from the questionnaire results and from the data of the applications made due to side effects. Results: 911 healthcare workers, 232 of whom had a history of COVID-19 were included in the study. The mean age of those with a history of COVID-19, was 36 (20-66), and 33.6% were men. 26.7% were doctors, 34.9% were nurses, 155 (66.8%) worked in internal and 62 (26.7%) in surgical units. There was no significant difference between the two groups regarding age, gender, task, and the departments they worked in. Comorbidities were present in 25.9% of the group with a history of COVID-19;the most common disease was asthma (5.6%). Allergy history was 4.3% in the group with COVID-19 and 7.8% in the other group (p=0.070). The incidence of post-vaccine adverse events (62.9%) was higher in those with a history of COVID-19 than in those without (57.1%). The most common adverse event was a headache, and it was significantly higher in the group who had COVID-19 compared to those who had not (36.6% vs. 27.7%;p=0.01). Conclusion: In our study, we observed that the rates of undesirable effects after vaccination were high in individuals with a history of COVID-19. Although it is thought that this situation may be related to the developing antibody response rates, the insufficient number of cases and the lack of determination of the antibody response after infection and vaccination are a disadvantage of the study.
ABSTRACT
Toxoplasmosis is a zoonotic illness that spreads from animals to people. Toxoplasma gondii, a protozoan parasite that infects warm-blooded mammals, causes the sickness. Toxoplasmosis is a parasitic infection that causes abortion and death in animals. Cats are the parasite's sole sexual hosts, thus they're the only ones who can get it. Because cats are frequent pets, they are highly likely to come into touch with humans. As a result, the disease poses a risk to human health. The potential danger is influenced by the frequency of oocyst secretion and the level of contamination in the environment. Toxoplasmosis has serious consequences for both animal and human health, hence preventative actions should be taken to reduce the dangers. COVID-19 is affected by such methods as well. Toxoplasmosis is thought to increase immunological and immunosuppressive factors, which increases the chance of SARS-CoV-2 infection and the severity of the resulting COVID-19. Research into Toxoplasma gondii intermediate hosts might help understand COVID-19's dynamics and determine if the virus can be transferred from animals to humans. We explore what we know about Toxoplasma gondii infection as a human parasitosis and how it may alter the course of SARS-CoV-2 infection in this review study.
ABSTRACT
Background: Monitoring the spread of SARS-CoV-2 has been considered by the World Health Organization (WHO). We examined the prevalence of anti-SARS-CoV-2 immunoglobulin antibodies in southwestern Iran in spring 2020. The circulation of SARS-CoV-2 is high in the general population, especially among health care workers (HCWs) who are in close contact with patients. Objectives: The aim of this study was to determine the prevalence of anti-SARS-CoV-2 antigen in high-risk occupational and low-risk groups to investigate risk factors for serum positivity in Shiraz, southwestern Iran. Methods: A cross-sectional survey was performed on 366 participants (204 from high-risk and 162 from low-risk subjects). IgG and IgM antibodies were detected using Pishtaz Teb COVID-19 ELISA Kits to evaluate SARS-CoV-2-antigen in serum samples. After enzyme-linked immunosorbent assay (ELISA), serum prevalence, as well as IgG/IgM positive factors, was determined using logistic regression. Results: From July to September 2020 (a few months after reporting the first case of COVID-19 cases in Iran), out of 366 survived people, 72 (40.9%) were IgG positive, and 50 (27.5%) were IgM positive. The frequency of positive serology for IgG and IgM antibodies in individuals aged < 30 years was higher in the low-risk group than in the high-risk group. Multivariate logistic regression showed that headache (OR 0.312 [95% CI: 0.136 - 0.717]) and cough (OR 0.427 [95% CI: 0.182 - 1.004]) factors were associated with IgG or IgM positive serology. Conclusions: Between July and September 2020, the prevalence of anti-SARS-CoV-2 antigen was high in Shiraz. The prevalence of SARS-CoV-2 IgG/IgM antibodies in the high-risk group and their family as low risk was shown to increase viral infection due to close contact with COVID 19 patients than in the general population. Several factors were found to be related to the prevalence of anti-SARS-CoV-2 antigen that needs to be considered by policymakers to determine what to do about the SARS-CoV-2 pandemic.
ABSTRACT
Background and Objectives: Serological studies are based on the detection of antibodies. However, the produced antibodies decrease over time;therefore, such methods cannot provide a valid estimate of prevalence and incidence. The present study aimed to determine the serum prevalence and cumulative incidence in the Ravansar cohort population (Youth and RaNCD Cohort) in October 2020. Methods: A random sample of 716 people aged > 18 years old were selected from the participants in the Ravansar cohort study in October 2020. Euroimmun anti-SARS COV-2 IgG ELISA kits (Lubeck, Germany) were used to measure antibody levels. Seroprevalence was estimated with considering of cut-off = 1, and cumulative incidence (modified and modified based on test specificity) was determined using modeling. Results: In the present study, the serum prevalence of COVID-19 viral infection in the Ravansar cohort population from 22 October 2020 to 18 November 2020 was estimated to be %35.16 (95%CI: %31.64, %38.79). Modified Cumulative incidence and modified based on test characteristics from 20 February to 18 November 2020 were estimated to be %68.85 and %67.71, respectively. Conclusion: Although very high cumulative incidence may be a sign of approaching herd immunity, adherence to health protocols is still recommended due to the potential role of asymptomatic cases in transmitting the disease to other members of the community;and the presence of new variants of the virus and reduced antibody levels should be considered.
ABSTRACT
The proteins (37%), carbohydrates (24.4%) and lipids (30.1%) contents of S. platensis from Nomayos provide the body with its structural and energy needs for about 518.8 Kcal per 100g of spirulina. Polyphenols (56.4 mEq. QE / g ES.), flavanols (13.2 mEq. QE / g ES.) flavonoids (21.2 mEq. QE / g ES.), carotenoids (3, 8%) and phycocyanin (16.15%) is responsible of its antioxidant capacities (7.5 + 0.33 mg eq. Vit C/g ES) and for a significant decrease in malondialdehyde MDA (< 0.001) concentration. Zinc (25 mG/Kg), Iron (256 mG/Kg), Selenium (1.24 mG/Kg), Manganese (23mG/Kg) and Copper (28.95 mG/Kg) reinforce this antioxidant power because they are cofactors of enzymes (Superoxide dismutase, Peroxidase, Catalase) which ensure the fight against free radicals. The presence of phycocyanin is an asset for the anti-inflammatory action. The significant decrease in IL-8 (p < 0.001) and TNF alpha (p < 0.04) levels confirms this property. On the other hand, the nonsignificant increase in Il-6 (1.56 to 2.18 pg/m;p > 0.05) would be partly responsible for the rise in CD4 levels (p < 0.001) and the reduction in viral load in immune deficiency patients (p = 0.000) supplemented with spirulina. In conclusion, S. platensis from Nomayos by its antioxidant, anti-inflammatory and immuno-stimulatory properties would be a good supplement food for subjects at risk of developing severe forms of COVID-19.
ABSTRACT
BACKGROUND: Efficacy of COVID vaccines has been evaluated in various studies. The interim analysis from four randomized controlled trials in UK, Brazil, and south Africa regarding efficacy of two doses of the vaccine was found to be 70.4% (95.8% CI 54.8-80.6). There is a limited data on follow-up Ab titer post vaccination. Hence, the current study is first of its kind with the objective to determine vaccine long term efficacy and its determinants. METHODS: Health Care Workers (HCW) from Apollo Multispeciality Hospitals, Kolkata who underwent Covishield vaccination from January 2021 to April 2021 were included in the study. Serological testing was done prior to first and second dose of vaccinations, and additionally around six months post second dose. RESULTS: Between January 2021 to April 2021, 2032 HCW, with predominant age of less than 30 years (44.83%) and male gender (61.96%) undergoing Covishield vaccination were enrolled. Antibodies were detected in 953 (46.9%) individuals prior to first dose, 1449 out of 1495 (96.9%) remained positive prior to second dose and 465 out of 504 (92.3%) HCW after 6 months and remaining 39 (7.7%) either had lost or never had antibodies in their blood. The mean +or- SD value of first, second and third antibodies were 2.35 +or- 3.10, 10.46 +or- 4.84 and 8.75 +or- 4.88 respectively. CONCLUSIONS: This study provides long observation period, covering the complete progress of the pandemic which provides a "real-life" picture of the antibody level dynamics over time, and after vaccination.
ABSTRACT
Objective: In COVID-19 disease, it was observed that T lymphocytes decreased numerically, both CD4+ and CD8+ could decrease, and sometimes the CD8+ level increased significantly. The virus-specific CD8+ T-cells are thought to be TEM or TEMRA cells. However, the characteristics of these cells, particularly their role in the pathogenesis of SARS-CoV-2 infection or COVID-19 disease, are unclear. Therefore, this study aimed to examine the flow cytometric changes observed in T helper, T cytotoxic cells, and subtypes during diagnosis in pediatric patients diagnosed with COVID-19 infection with SARS-CoV-2 PCR positivity. Methods: Twenty-two children aged 0-18, diagnosed with COVID-19, with flow cytometry;T Helper Cell (TH), T Cytotoxic Cell (TC), T Naive Cells (TN), Central Memory (TCM), Effector Memory (TEM), RA + Effector memory (TEMRA) and Recent Thymic Emigrants (RTEs) were studied. Results: T cell counts were found to be expected in all age groups. The CD4/CD8 ratio increased in the under-five and over 16 age group. While TCM among CD4+T cells decreased in the group above 16 years of age, TEM decreased in all age groups. RTEs decreased in all except the age group 16+. Naive CD8+ T cells (TN) were found to be high in all age groups. Conclusion: A low number of CD4+ and CD8+ lymphocytes have been reported as a distinctive laboratory finding in 2019 Coronavirus disease (COVID-19). Having enough naive T cells is essential for the immune system to respond consistently to unknown pathogens. This study found that these cells were higher than expected in children.
ABSTRACT
Introduction: Proinflammatory cytokines, produced as an immune response in severe acute respiratory syndrome-coronavirus 2 infection, activate the coagulation cascade as well. In this study, we investigated the difference in the clinical course of patients who had been already using anti-thrombotic therapy before coronavirus disease-2019 (COVID-19) for any reason compared to the group who had not. Methods: In this retrospective, multicenter study;patients who were hospitalized between March 11 and July 1, 2020 were divided into two main groups as who had been on anti-thrombotic therapy for any indication use previously at the time of admission or who had not been on anti-thrombotic therapy at the time of admission, and their selected clinical parameters were compared. Results: After analyzing the study population of 124 patients with a homogeneous distribution in terms of age and gender, the comparison of anti-thrombotic users and non-users showed no significant difference in hospitalization. There was a statistically significant decrease in mechanical ventilation apply rate, intensive care unit duration and mortality rate between the group using anti-thrombotic compared to the group not using it (p<0.05). Conclusion: It has already been shown that COVID-19 patients are more prone to thromboembolic events as it activates the coagulation cascade with the cytokine storm it creates and thus the mortality of COVID-19 infection increases significantly. Parallel to this fact the results of our study demonstrated that using anti-thrombotic therapy for any reason may affect the bad prognosis of the disease positively.
ABSTRACT
Our manuscript focuses on vegetables and fruits as functional foods. Our questionnaire survey was conducted at the end of the third wave of the pandemic, however, we also paid increased attention to lifestyle, mostly dietary, changes in the active stages of the coronavirus pandemic, especially vegetable and fruit consumption patterns. Our quantitative analysis was carried out with the help of 9 questionnaires, including 4 cumulative closed-ended questionnaires, which were divided into four main groups of statistical activities. We first analysed demographic data and then focused on health status, knowledge of concepts, and assessment of consumer needs. For the statistical evaluation of our survey, we performed a descriptive statistical analysis, including a distribution analysis of demography and related issues. Next, we calculated the appropriate type of correlation between the questions, which was evaluated in Microsoft Excel and IBM SPSS Statistics 26. The number of respondents was n = 109, of which 37% were male and 63% female. Before evaluating our results, we also asked a research question: To what extent did the attitudes related to regular exercise, healthy eating and the importance of health change during the active stages of the pandemic? Based on our empirical analyses, an increase in extremes can be observed with regular exercise. In terms of general health, there was an increase in the "extremely important" category. In the active phase of the pandemic, the number of vegetable consumers was lower, and among the proponents of a healthy diet, the consumption of fruit foods was not significantly higher. Based on our conclusions, this is due on the one hand to the restrictions during the pandemic and on the other hand to the endowment of fruit-containing foods with negative properties (e.g. made with the addition of sugar).
ABSTRACT
Background and Objectives: Autism spectrum disorder (ASD) is a neuro-developmental disorder which is mostly caused by deficits in social interactions. Lack of physical activity and poor nutritional habits are common problems in these patients which may be exaggerated by the Covid-19 pandemic. The study aims to assess the effect of functional training along with online nutrition education on inflammatory biomarkers in children with ASD. Subjects and Methods: In this randomized controlled clinical trial, 80 children with ASD (age=9.73+or-1.29 years, weight=49.94+or-2.08 kg, height=146.08+or-40 cm, body mass index=24.71 +or-1.48 kg/m2) were randomly divided into four groups of training, education, training+ education, and control. The interventions lasted for 8 weeks. The inflammatory biomarkers including white blood cell (WBC) count, C-reactive protein (CRP) level, neutrophil count, eosinophil count, and basophil count were assessed (using blood samples collected from antecubital vein) before and after the interventions. Results: There was no significant difference between the groups before the interventions (P>0.05). After the intervention, the results showed a significant decrease in WBC (P<0.001), CRP (P=0.001), neutrophils (sig.=0.009), and eosinophil (P=0.003) in all groups. Basophil count decreased in all groups (P=0.01) except in the education group. Conclusion: Functional training and online nutrition education are beneficial interventions for management of inflammatory biomarkers in children with ASD which can be used during the Covid-19 pandemic.
ABSTRACT
The article is devoted to the global problems of modern medicine - HIV infection and the COVID-19 pandemic. The review of the literature highlights current ideas about the pathogenesis and course of COVID-19 in patients with HIV infection, and also touches upon the problems of concomitant pathology and mental health of patients with HIV in the setting of the COVID-19 pandemic. It has been shown that HIV-positive patients are a risk group for the severe course of COVID-19, in particular, individuals with severe immunodeficiency (CD4+ T lymphocytes 200 cells/l) due to the development of synergetic lung damage by SARS-CoV-2 and secondary infectious agents such as cytomegalovirus and Pneumocystis carinii. It has been proven that one of the targets of the SARS-CoV-2 virus is CD4+ T cells, which in COVID-19 leads to a more rapid progression of immunodeficiency in patients with HIV infection and, thus, significantly increases the risk of secondary diseases and death. Particular attention should be paid to middle-aged and elderly people living with HIV, who, compared with HIV-negative patients, are more likely to have concomitant pathology - arterial hypertension, cardiomyopathy and diabetes mellitus, which are the risk factors for severe COVID-19. The results of studies on the effect of antiretroviral drugs on the course of COVID-19 showed that HIV-infected patients receiving tenofovir + emtricitabine have a lower risk of severe COVID-19 and associated hospitalization than patients receiving other HIV treatment regimens. Clinical and preclinical data support the potential use of tenofovir in the treatment of novel coronavirus infection.
ABSTRACT
Introduction: the daily increase in cases and deaths, the economic losses in the millions suffered by affected nations and the consequent strain on the human resources involved in reversing this situation have made the COVID-19 pandemic an unprecedented international challenge. Background: to describe the orchestrated immune response following SARS-CoV-2 infection. Methods: an up-to-date bibliometric study was conducted on the type of articles stated in the objective, using a total of 30 bibliographies. Documentary review and analysis-synthesis methods were used to prepare the final report. Resources available on the Infomed network were used to select the information, specifically: PubMed and SciELO, through the databases: Medline, Search Premier and Scopus. Development: the core elements in the immunopathology of COVID-19 involve innate immunity, with the sustained increase of pro-inflammatory interleukins associated with failures in the interferon system, which can trigger a potentially fatal cytokine storm. In terms of elements linked to adaptive immunity, there is evidence of marked lymphopenia which, depending on the degree, may indicate the severity of the disease. Conclusions: understanding the orchestrated immune response following SARS-CoV-2 infection and its temporal sequence allows us to choose timely and effective therapies, specifically when selecting anti-inflammatory drugs and the time of their application, as it is difficult to determine when they will be clearly beneficial, that they do not impair the response and that it is not too late, given the irreversibility of the process.
ABSTRACT
Increasing body immunity is very necessary after the Covid-19 pandemic. One of the efforts that can be made to increase the body's immunity is to consume functional foods with immunostimulant activity, such as processed snakehead fish products in the form of nuggets, and "parkusel" juice made from a mixture of bitter melon, dates and celery. The purpose of community service is to provide knowledge and skills to housewives and the community at the Veteran ABRI Housing Complex in Medan Estate, Deli Serdang Regency, in making functional food products in the form of snakehead fish nuggets and Perkusel juice. The community service method used is the counseling method with leafet aids and training in making snakehead fish nuggets and perkusel juice. The results of the activity showed that there was an increase in the knowledge of the community participants in community service activities about nutritious snack products that can increase body immunity by 71% in the good value category.
ABSTRACT
Background: The severity of COVID-19 can be detected by examining elevated levels of CRP, ferritin, IL-6 and LDH. Elevated D-dimer levels are often found in patients with severe COVID-19 which can predict the occurrence of ARDS (Acute Respiratory Distress Syndrome) and patient mortality. The purpose of this study was to determine how much influence D-dimer levels had on mortality of COVID-19 patients. Subjects and Method: This study used a systematic review and meta-analysis with following PICO, population: patients with a clinical diagnosis of COVID-19. Intervention: high D-dimer level. Comparison: low D-dimer level. Outcome: mortality. The data used were obtained from scientific research articles from Pubmed, Google Scholar, Science Direct, and Proquest electronic databases with a cohort design in 2020 until 2022 and report on aOR in multivariate analysis. The keywords used in the search for scientific articles were "D-dimer level" OR "D-dimer" AND "COVID-19" AND "mortality". The selection of articles is done by using PRISMA flow diagram. Data were analyzed using Review Manager software version 5.4.1. Results: A total of 12 studies with a cohort design that met the criteria from Asia, America, and Europe were selected for a systematic review and meta-analysis. Based on the meta-analysis, it was found that increased levels of D-dimer (>0.5 g/mL) increased mortality in COVID-19 patients by 6.40 times compared to low levels of D-dimer (0.5 g/mL) and was statistically significant (aOR=6.40;95% CI= 4.51 to 9.08;p < 0.001). Conclusion: Elevated levels of D-dimer may increase mortality risk in COVID-19 patients.
ABSTRACT
Pregnant women generally constitute a group at high risk of infectious diseases due to gestational immunological and physiological changes in their system. That is why the objective of this work is to analyze the implications of the physiological changes of pregnancy in SARS-CoV-2 disease. Physiological changes in pregnant women not only increase their susceptibility to the virus, but also increase the severity of the disease. Changes in the respiratory and immune systems, the role of the placenta in coagulation, and the function of endothelial cells are the physiological changes that most influence the disease. The decrease in lung capacity and the variations that occur in the immune system represent new treatment challenges for pregnant women with COVID-19 disease and therefore new areas of research limited so far.
