ABSTRACT
Objectives: COVID-19 had an impact on health care, including diagnostics. Early diagnosis of MM is a critical factor for prognosis. We examined the impact of COVID-19 on incidence of NDMM patients and on characteristics in NDMM patients in US and in Germany. Method(s): 44,164 NDMM patients were identified in TriNetX federated network across 55 healthcare organizations in US between January 2018 and December 2021. A bivariate analysis examined changes in patient characteristics in two cohorts before (Cohort 1;n=25513) and after (Cohort 2;n=18.651) the start of the COVID-19 pandemic in March 2020. 4172 NDMM patients were identified in the German database in a sample of across >100 healthcare organizations in the same time period. Similarly, bivariate analysis examined changes in patient characteristics before (Cohort 1;n=2252) and after (Cohort 2;n=1920) the start of pandemic. Result(s): Analysis of US data showed a significant decrease in incidence of NDMM. Bivariate analysis revealed that NDMM patients in Cohort 2 have a significantly higher risk profile compared with patients in Cohort 1, higher incidence of renal failure (13.5% v. 15.43%), heart failure (10.3% v 11.26%), bone lesions (12.6% v. 13.05%) and anemia (26.8% v. 29.75%). The German data indicated an increased risk profile in Cohort 2, with higher reporting of renal impairment (12.3% v. 15.5%) and cardiac impairment (8.3% v. 10.9%). The higher risk profile was reflected in a significant increase of all SLiM-CRAB criteria, notably hypercalcemia (24.1 % v. 36.9%), bone marrow plasma cell infiltration (28.1% v. 36.8%) and free light chain involvement (27.3% v. 41.3%). Conclusion(s): The results provide real-world evidence of a change in risk profile for patients with NDMM during COVID-19. This higher risk profile is observed in both the US and Germany, and may negatively impact outcomes such as progression-free and five-year overall survival.Copyright © 2023
ABSTRACT
Objectives: The study aims to determine the influence of the efficiency of the cervical cancer program on the budget execution during the COVID-19 pandemic years 2020- 2021. Method(s): Estimating the screened women and using a micro-costing analysis to estimate the cost of treating precancerous lesions and cervical cancer in the pandemic and a non-pandemic scenario during 2020 -2021. Finally, the estimation of the budget execution for the cervical cancer program led by the Ministry of Health in the pandemic and non-pandemic scenarios. The estimation in the study was through two scenarios determined, the pandemic and non-pandemic scenarios during the years 2020 and 2021. After that, it was determined the number of screened and non-screened women. The next step was the cost estimation of the low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesions (HSIL), and cervical cancer at different stages. Therefore, this information is necessary for the Peruvian Ministry of Health to provide healthcare services to patients who did not get screened in the years 2020 and 2021. Result(s): The non-pandemic scenario would be spent USD 33,547,185 and USD 37,428,997 in 2020 and 2021, respectively. Conversely, in the pandemic scenario, spent USD 9,934,440 and USD 23,762,073 by 2020 and 2021. Therefore, by 2020 must be spent 68.7% of the budget, but only had been spent 20.3%. Moreover, in 2021, only 46.7% of the budget was spent when it should be 73.6% of the total budget. Therefore, USD 39,496,476 and USD 27,114,114 were not executed in 2020 and 2021, respectively. Conclusion(s): A total of USD 66,610,590 was the non-executed budget for the cervical program and needs to be reallocated in the following years to provide healthcare services to the women who did not get access to screening and treatment.Copyright © 2023
ABSTRACT
Introduction: Universities represent important Centers for public health assistance. However, in the context of the COVID- 19 pandemic, most Brazilian universities have suspended their academic activities and outpatient care. Objective(s): Describe how the Teleconsultation Program in Oral Medicine of the School of Dentistry, Brazil, remotely contributes to counseling dentistry on diagnosing oral lesions and providing guidance on treating patients in the North Macro-region of Minas Gerais state. Material(s) and Method(s): Teleconsulting takes place remotely;the professional sends by smartphone, via WhatsApp, the case report, clinical images, and complementary exams, if appropriate. Concerning this, the specialist team analyzes the clinical case and returns it to the professional sender, providing information and suggestions on the oral lesions' diagnostic assessment and clinical management. Result(s): Since the beginning of the program, in 19 months, dentists from 40 municipalities were counseled, which resulted in 287 teleconsultations;from these cases, 103 cases were conducted face-to-face consultations in our Oral Diagnosis Service, and 38 cases were hypothesized as malignant lesions in the oral cavity and had their medical treatment conducted and followed by a multidisciplinary team, when appropriate. Conclusion(s): Teleconsultation Program represents an important tool to strengthen the communication between professionals of public health, improve health work processes, and promote better clinical guidance in Oral Medicine.
ABSTRACT
Spontaneous pneumomediastinum, pneumothorax, pneumoperitoneum, and soft tissue emphysema have been recently described in several sources as possible complications in patients with severe COVID-19 and lung damage. This clinical case is dedicated to demonstrarte the development of these lesions in 3 male patients with comorbid conditions. The putative pathophysiological mechanism of these complications is air leakage due to extensive diffuse alveolar damage followed by rupture of the alveoli. All presented patients had a favorable outcome of the disease without lethal cases, their laboratory data and clinical dynamics were described. It should be noted that such conditions are not rare complications of COVID-19, and are observed mainly in male patients with severe form of the disease and the presence of comorbid conditions. Such complications are associated with long hospitalization and a severe prognosis. In some cases, with a mild course of the disease and positive dynamics in a decrease of the percentage of pulmonary lesions, the outcome is favorable, not requiring additional invasive interventions.Copyright © 2022 Medical Visualization.

ABSTRACT
The CT images of lungs of COVID-19 patients have distinct pathological features, segmenting the lesion area accurately by the method of deep learning, which is of great significance for the diagnosis and treatment of COVID-19 patients. Instance segmentation has higher sensitivity and can output the Bounding Boxes of the lesion region, however, the traditional instance segmentation method is weak in the segmentation of small lesions, and there is still room for improvement in the segmentation accuracy. We propose a instance segmentation network which is called as Semantic R-CNN. Firstly, a semantic segmentation branch is added on the basis of Mask-RCNN, and utilizing the image processing tool Skimage in Python to label the connected domain for the result of semantic segmentation, extracting the rectangular boundaries of connected domain and using them as Proposals, which will replace the Regional Proposal Network in the instance segmentation. Secondly, the Atrous Spatial Pyramid Pooling is introduced into the Feature Pyramid Network, then improving the feature fusion method in FPN. Finally, the cascade method is introduced into the detection branch of the network to optimize the Proposals. Segmentation experiments were carried out on the pathological lesion segmentation data set of CC-CCII, the average accuracy of the semantic segmentation is 40.56mAP, and compared with the Mask-RCNN, it has improved by 9.98mAP. After fusing the results of semantic segmentation and instance segmentation, the Dice coefficient is 80.7%, the sensitivity is 85.8%, and compared with the Inf-Net, it has increased by 1.6% and 8.06% respectively. The proposed network has improved the segmentation accuracy and reduced the false-negatives. © 2022 ACM.
ABSTRACT
With the COVID-19 outbreak in 2019, the world is facing a major crisis and people's health is at serious risk. Accurate segmentation of lesions in CT images can help doctors understand disease infections, prescribe the right medicine and control patients' conditions. Fast and accurate diagnosis not only can make the limited medical resources get reasonable allocation, but also can control the spread of disease, and computer-aided diagnosis can achieve this purpose, so this paper proposes a deep learning segmentation network LLDSNet based on a small amount of data, which is divided into two modules: contextual feature-aware module (CFAM) and shape edge detection module (SEDM). Due to the different morphology of lesions in different CT, lesions with dispersion, small lesion area and background area imbalance, lesion area and normal area boundary blurred, etc. The problem of lesion segmentation in COVID-19 poses a major challenge. The CFAM can effectively extract the overall and local features, and the SEDM can accurately find the edges of the lesion area to segment the lesions in this area. The hybrid loss function is used to avoid the class imbalance problem and improve the overall network performance. It is demonstrated that LLDSNet dice achieves 0.696 for a small number of data sets, and the best performance compared to five currently popular segmentation networks. © 2023 SPIE.
ABSTRACT
Background: Ever since the beginning of the COVID-19 pandemic, physicians started investigating the clinical features and lab markers that can assist in predicting the outcome among hospitalized COVID-19 patients. Aim(s): This study aimed to investigate the association between initial chest CT scan findings and adverse outcomes of COVID-19. Material(s) and Method(s): This was a single centre;hospital (inpatient) based prospective cohort study involving 497 COVID-19 patients admitted to the hospital. The adverse outcome included death and mechanical ventilation. We collected data about 14 identifiable parameters available for the HRCT scan. Result(s): Among 14 studied parameters, only 8 features differed significantly among the patients who had favourable and unfavourable outcomes. These features included number of lobes of lungs involved (3 versus 5, p = 0.008), CT Severity score (16 versus 20, p = 0.004), air bronchogram (p=0.003), crazy paving (p=0.029), consolidation (p=0.021), and pleural effusion (p=0.026). We observed that high CT scores coupled with the diffuse distribution of lung lesions were responsible for poor prognosis in most patients. Conclusion(s): Several features of HRCT when combined can accurately predict adverse outcomes among participants and help in triaging the patient for admission in ICU.Copyright © 2023, Dr Yashwant Research Labs Pvt Ltd.

ABSTRACT
Introduction: Several studies have evaluated the occurrence of oral lesions and changes in sensory functions in patients positive for COVID-19. Objective(s): To evaluate the manifestations of COVID-19, emphasizing olfactory and gustatory changes, xerostomia, and oral lesions. Material(s) and Method(s): A cross-sectional and observational study was conducted. Approved by the Institutional Ethics Committee (#46151121.6.0000.5141). All patients were diagnosed by reverse transcription-polymerase chain reaction assay (RT-PCR) and considered to have mild symptoms, according to the latest WHO joint report. The patients were evaluated at a reference Service for COVID-19 in Minas Gerais, Brazil. The oral cavity was evaluated for each patient on the second and seventh days. Result(s): A total of 414 patients older than 18 years were evaluated. One hundred thirty-nine presented at least one of the studied conditions, oral lesions (19.08%) were the most frequently observed, followed by gustatory disorders (18.11%), xerostomia (14.25%), and olfactory dysfunction (14%). Among the oral lesions, there were various anatomical locations and clinical presentations. The occurrence involving lips and tongue represented 49 oral lesions, the most prevalent being, respectively, ulcerations (n=51), candidiasis (n=8), and erythema or red plaques (n=7). Fifty patients died. Conclusion(s): This study represents, to date, the largest case series of oral lesions in Brazilian patients with COVID-19, and oral alterations were observed in an expressive percentage of patients with COVID-19. However, it cannot be concluded that SARS-CoV-2 directly causes them.

ABSTRACT
Introducción. La lesión renal aguda (LRA) en el paciente con COVID-19 ocurre más frecuentemente en presencia de enfermedades crónicas como diabetes, obesidad, hipertensión arterial y enfermedad renal crónica previa, considerándose un fuerte predictor de resultados desfavorables y mortalidad. El propósito de este estudio fue describir las características histopatológicas en biopsias renales de pacientes hospitalizados por COVID-19, que experimentaron algún grado de daño renal durante su hospitalización. Metodología. Se incluyeron 30 pacientes mayores de 18 años, hospitalizados en diferentes centros de atención en Medellín, Colombia, con diagnóstico confirmado de COVID-19, sin antecedente de terapia de reemplazo renal, que durante la infección desarrollaron algún grado de daño renal, y que tuvieran estudio histopatológico de biopsia renal. Se analizaron las características demográficas, formas clínicas de presentación y hallazgos histopatológicos a nivel renal. Resultados. La mayoría de los pacientes eran de sexo masculino (70%). Los antecedentes patológicos más frecuentes fueron la enfermedad renal crónica previa (16,7%), diabetes mellitus (16,7%), trasplante renal (13,3%) y VIH (10%). El 35,7% de los pacientes no tenían ninguna comorbilidad subyacente. La manifestación clínica inicial más frecuente fue la LRA (56,7%). Algunos pacientes tuvieron más de una manifestación clínica inicial. El 100% de los pacientes evaluados tuvieron hallazgos histopatológicos renales, siendo la nefritis tubulointersticial aguda (40%) el más frecuente. Conclusión. Nuestro estudio no descarta una posible asociación del sexo masculino con peores desenlaces en la enfermedad COVID-19. La LRA fue el hallazgo clínico inicial más frecuente. Es posible que los hallazgos histopatológicos del presente estudio puedan ser consecuencia del daño directo a nivel tubulointersticial renal y la mala perfusión renal, dado el estado de choque por la tormenta inflamatoria, el empeoramiento de enfermedades preexistentes, o la superposición clínica con otras entidades. Sin embargo, son necesarios más estudios para dilucidar los mecanismos por los cuales se generan estas lesiones
Acute kidney injury (AKI) in patients with COVID-19 occurs more frequently in the presence of chronic diseases such as diabetes, obesity, hypertension, and previous chronic kidney disease, and is considered a strong predictor of unfavorable outcomes and mortality. The purpose of this study was to describe the histopathological characteristics in kidney biopsies from patients hospitalized for COVID-19, who experienced some degree of kidney damage during their hospitalization. Methodology. We included 30 patients over 18 years of age, hospitalized in different care centers in Medellín, Colombia, with a confirmed diagnosis of COVID-19, without a history of renal replacement therapy, who developed some degree of kidney disease during the infection, and had histopathological study of renal biopsy. Demographic characteristics, clinical manifestations and histopathological findings were analyzed. Results. Most of the patients were male (70%). The most frequent previous pathological findings were chronic kidney disease (16.7%), diabetes mellitus (16.7%), kidney transplant (13.3%) and HIV (10%). 35.7% of the patients did not have any underlying comorbidity. The most frequent initial clinical manifestation was AKI (56.7%). Some patients had more than one initial clinical manifestation. 100% of the patients had renal histopathological findings, with acute tubulointerstitial nephritis (40%) being the most frequent. Conclusion. Our study does not rule out a possible association of the male gender with worse outcomes in COVID-19 disease. AKI was the most common initial clinical finding. It is possible that the histopathological findings of this study may be a consequence of direct damage at the renal tubulointerstitial level and poor renal perfusion due to the inflammatory storm, worsening of pre-existing diseases, or clinical overlap with other entities. However, more studies are needed to elucidate the mechanisms by which these lesions are generated

Aim. To determine the clinical efficacy and safety of the immobilized (sorbed) probiotics Bifidobacterium bifidum 1 (5x108 CFU) and B. bifidum 1 (5x107 CFU) in combination with Lactobacillus plantarum 8P-A3 (5x107 CFU) in the complex therapy of pneumonia caused by SARS-CoV-2 in adult patients without severe risk factors and their impact on health-related quality of life (QoL). Material and methods. An open, randomized prospective study included 100 patients (45 males, 55 females), aged from18 to 60 years without risk factors for severe COVID-19, with pneumonia confirmed by computed tomography and an area of lung lesion no more than 75% (moderate forms). SARS-CoV-2 RNA in nasal and oropharyngeal swabs (RT-PCR) was detected in 72% of the participants, in the rest it was highiy probable in terms of the aggregate parameters. The publication presents the results of self-assessment (94 respondents) of working capacity limitations, shortness of breath, intestinal disorders since the end of the probiotic regimen (PR: hospitalization period - B. bifidum 1, 3 capsules 2 times a day for 10 days, then after hospitalization - B. bifidum 1 in combination with L. plantarum 8P-A3 2 powders 3 times a day for 14 days) and QoL (Short Form Medical Outcomes Study: SF-36) 1 month after hospitalization. Results. At the end of PR, the ability to engage in daily activities was higher by 23.1% [95% confidence interval 5.3-37.3, OR 0.08 (0.08-0.77)]. Difficulty of breathing during exercise was less common by 29.7% [15.1-44.5%], OR 0.09 [0.02-0.40], hard stools and no bowel movements were recorded less often by 21.3% [8.5-34, 1] for 1-3 days. One month after hospitalization, the QoL of the patients receiving standard treatment was significantly reduced relative to population indicators in Russia. It was more significantly due to the psychological component of health [total measurement 38.1 (36.2-40.0)] and less significantly due to the physical component [49.5 (48.3-50.8)]. The main reasons limiting daily activities [Role Emotional (RE): 39.4 (37.4-41.4)] were decreased vitality [VT: 40.2 (38.9-041.5)], emotional depression [Mental Health (MH): 41.2 (39.4-43.0)], deficit of social contacts [Social Functioning (SF): 45.1 (43.7-46.6)]. The patients who received PR had a higher ability to carry out daily activities [RE: 57.7 (55.6-59.7)], the severity of psychological problems associated with fatigue, anxiety and depression was lower [MH: 59.8 (58.7-60.9), p<0,001]. The effect of the PR on negative perceptions of social isolation was comparatively less [SF: 53.9 (52.2-55.4)]. The QoL of the patients who additionally suffered from diarrhea in the acute period of SARS-CoV-2 pneumonia was worse in comparison with the patients without diarrhea (due to pain and inability to endure physical activity). The effects of immobilized (sorbed) probiotics to the QoL of the patients with diarrhea during the acute period of COVID-19 were most significant. Conclusion. PR had a significant positive effect on the QoL within a month after hospitalization, increasing working capacity and improving mental health, reducing the severity of psychological problems and fatigue. Additional researches are needed on the possible relationship of organic and functional gastrointestinal diseases with the progression of diarrhea in patients infected with SARS-CoV-2. No side effects of the sorbed probiotics regimen have been identified.Copyright © Eco-Vector, 2022.
ABSTRACT
The development of coronavirus infection outbreak into a pandemic, coupled with the lack of effective COVID-19 therapies, is a challenge for the entire pharmaceutical industry. This study aimed to assess the treatment and preventive efficacy of the amino acid-peptide complex (APC) in male Syrian hamsters infected with SARSCoV-2 (intranasal administration of 26 mul of the virus culture, titer of 4 x 104 TCD50/ml). In a modeled COVID-19 case, APC administered for treatment and preventive purposes reduced lung damage. Compared to the positive control group, test group had the lung weight factor 15.2% smaller (trend), which indicates a less pronounced edema. Microscopic examination revealed no alveolar edema, atypical hypertrophied forms of type II alveolocytes, pulmonary parenchyma fibrinization. The macrophage reaction intensified, which is probably a result of the APC-induced activation of regenerative processes in the lung tissues. Spleens of the animals that received APC for therapeutic and preventive purposes were less engorged and had fewer hemorrhages. The decrease of body weight of the test animals that received APC for treatment and prevention was insignificant (p < 0.05), which indicates a less severe course of COVID-19. Administered following a purely therapeutic protocol, APC proved ineffective against SARS-CoV-2 post-infection. Thus, APC-based drug used as a therapeutic and preventive agent reduces pulmonary edema and makes morphological signs of lung tissue damage less pronounced in male Syrian hamsters infected with SARS-CoV-2.Copyright © Extreme Medicine.All right reserved.
ABSTRACT
Introduction: Acute pancreatitis affects a significant population globally. Usual etiologies are gallstones, alcohol, hypertriglyceridemia, medications;less frequent are trauma, hypercalcemia, infections, toxins, ischemia, anatomic anomalies, vasculitis, and idiopathic. Pancreatitis post coronary intervention is an uncommon cause with only 19 published cases in the last two decades. Being cognizant of this etiology is important given the increasing number of patients undergoing angiography. Case Description/Methods: An 81-year-old female with hypertension, diabetes, peripheral arterial disease, prior cholecystectomy underwent left lower extremity angioplasty at an outside center. Within a few hours, she started having severe epigastric pain radiating to her back, nausea, vomiting and loose bloody stool. She presented to the emergency department 24 hours after symptom onset. Epigastric tenderness was present on exam. Labs revealed leukocytosis (24,450/muL), elevated lipase (1410 U/L), elevated creatinine (1.3 mg/dL), lactate (3.1 mmol/L), calcium 9.4 mg/dL and triglycerides 161 mg/dL. Incidentally, found to be positive for COVID-19. Normal common bile duct diameter seen on sonogram. CT angiogram of the abdomen/pelvis showed acute pancreatitis, duodenal and central small bowel enteritis (Figure). She was not on any medications known to cause pancreatitis and denied alcohol use. Patient improved with analgesics and intravenous fluids. She had no recurrence of bloody stools and hemoglobin remained stable. On day 4, she was able to tolerate a regular diet, and leukocyte count and creatinine normalized. Patient did not have any COVID respiratory symptoms, and was discharged. Discussion(s): Given the temporal association to angioplasty and no other identifiable cause, acute pancreatitis was presumed to be due to the contrast used during angioplasty. Other possibilities included cholesterol embolism but no peripheral signs of cholesterol embolism were seen. Patient was an asymptomatic COVID-19 case. Although, there are case series of pancreatitis due to COVID, those were found in very sick symptomatic patients. On review of literature, cholesterol embolism was identified as a definite cause only on autopsy or laparotomy (Table). Other possible mechanisms are: high viscosity of the contrast media leading to ischemia and necrosis, contrast causing NF-kB activation followed by epithelial damage, and vasospasm. Pancreatitis after coronary angiography is rare, nonetheless, an important differential especially if there is a temporal relationship.
ABSTRACT
The most common clinical manifestation of new coronavirus infection is bilateral pneumonia. At the same time, COVID-19 has a wide range of cardiovascular complications, with the development of acute heart failure, arrhythmias, acute coronary syndrome, and myocarditis. Myocardial injury is relatively common in COVID-19, accounting 7-23 % of cases. The presented clinical case describes a 56-year-old patient with a confirmed coronavirus infection. The peculiarity of this clinical case is that it is the first report on COVID-19 with systemic manifestations: lungs, heart, kidneys and skin lesions. It should be noted that despite viral pneumonia typical for COVID-19, clinical picture and severity of the patient's condition were determined by the developed myocardial injury. The presented clinical case is specific due to skin lesions.Copyright © 2021, Krasnoyarsk State Medical University. All rights reserved.
ABSTRACT
Background: There is still no specific treatment strategy for COVID-19 other than supportive management. The potential biological benefits of ozone therapy include reduced tissue hypoxia, decreased hypercoagulability, modulated immune function by inhibiting inflammatory mediators, improved phagocytic function, and impaired viral replication. This study aimed to evaluate the effect of intravenous ozonated normal saline on patients with severe COVID-19 disease. Method(s): In this study, a single centralized randomized clinical trial was conducted on 80 hospitalized patients with severe COVID-19. The patients were selected by random allocation method and divided into two groups A and B. In group A (control group), patients were given standard drug treatment, and in group B (intervention group), patients received ozonated normal saline in addition to the standard drug treatment. In the intervention group, 400 mL of normal saline was weighed by 40 mug/ kg of body weight and was injected into patients within 15 to 30 minutes (80 to 120 drops per minute). This process was done daily every morning for a week. Primary and secondary outcomes of the disease included changes in the following items: length of hospital stay, inflammatory markers including C-reactive protein (CRP), clinical recovery, arterial blood oxygen status, improvement of blood disorders such as leukopenia and leukocytosis, duration of ventilator attachment, and rapid clearance of lung lesions on CT scans. The need for intensive care unit (ICU) hospitalization, the length of ICU stay, and the mortality rate in patients of the two groups was compared. Result(s): According to the results of the initial outcome variable analysis, the probability of discharge of patients who received the normal ozonated saline intervention was 33% higher than patients who did not receive this intervention;however, this relationship was not statistically significant (HR = 0.67, 95%, CI = 0.42-1.06, P value = 0.089). The chance of ICU hospitalization in patients of the intervention group was three times more than that of the comparison group, but this relationship was not significant (odds ratio = 4.4 95% CI = 1.32-14.50, P value = 0.016). The use of ozonated normal saline was found to increase the risk of death by 1.5 times but this relationship was not statistically significant (odds ratio = 1.5, 95% CI = .24-9.75, P value = 0.646). Ozonated normal saline had a significant effect on changes in respiration rate (in the intervention group the number of breaths was decreased) and the erythrocyte sedimentation rate (in the intervention group the erythrocyte sedimentation rate was increased);however, it had no significant effect on other indicators. Conclusion(s): The present study showed that ozone therapy in hospitalized patients with severe COVID-19 could help improve some primary and secondary outcomes of the disease. Governments and health policymakers should make ozone therapy an available care service so that the need for advanced treatment facilities decreases;consequently, this measure may improve patient safety, prevent lung tissue destruction, and control cytokine storms in patients. Additionally, health decision-makers need to aim for the effective clinical improvement of patients, especially severe ones, and the reduction of their mortality. However, further large-scale multicenter studies with larger sample sizes considering drug side effects and other variables influencing the clinical course of COVID-19 can provide more information on the effectiveness and importance of ozone therapy.Copyright © 2023 The Author(s);Published by Kerman University of Medical Sciences.
ABSTRACT
Pandemic of COVID-19 has brought significant changes not only to the daily life of mankind, but also to the course of many chronic diseases. In addition to lung damage, extrapulmonary manifestations may develop against the background of coronavirus disease progression. These changes often have multi-organ nature, espe cially against the background of existing chronic diseases. Literature describes cardiac, neurologic, renal extrapulmonary SARS-CoV-2 lesions as well as eye damage. Gastrointestinal tract is one of the areas affected by SARS-CoV-2 virus. This impact is stipulated by the significant effects of virus on the microbiota and permeability of mucosal barriers, as well as important role of changes in the intestinal barrier function in the development of local and systemic immune response. Working group of the Ukrainian Gastroenterological Association (UGA) worked out a classification of intestinal post-covid lesions, which was presented at the UGA congress in September 2021. The following types of damage have been outlined: COVID-19 induced bacterial overgrowth syndrome, functional diarrhea after previous COVID-19 infection, infection-induced irritable bowel syndrome (post-infectious IBS), antibiotic-associated diarrhea (without Clostridium difficile and pseudomembranous colitis with confirmed Clostridium difficile), exacerbation of inflammatory bowel disease (ulcerative colitis, Crohn's disease), newly diagnosed (COVID-induced) inflammatory bowel disease. The course of functional and inflammatory diseases can be modified by COVID-19, affecting the gut microbiome. It is necessary to conduct a thorough differential diagnosis of exacerbation of functional, inflammatory and post-covid lesions of the intestine. Complex therapy including agents to correct dysbiosis should be used to treat this group of patients. © Modern gastroenterology, 2022.
ABSTRACT
Background: Coronavirus disease 2019 (COVID-19) was first identified in 2019 in Wuhan, China. Initially, although the number of COVID-19-infected individuals was very low, the infected cases increased as the virus spread worldwide. Skin manifestation is one of the symptoms observed in COVID-19 patients. Objectives: This study investigated the critical genes and molecular pathways involved in skin manifestations in COVID-19 patients through a biological system approach. Methods: In this study, the microarray dataset was downloaded from the Gene Expression Omnibus (GEO) database and analyzed for identifying differentially expressed genes (DEGs). The enrichment analysis of DEGs was evaluated using the DAVID database. Afterward, protein-protein interaction (PPI) networks were constructed via the STRING database and visualized using Cytoscape software. The hub genes were recognized using the cytoHubba. The interaction of the microRNA (miRNA)-hub genes, transcription factor (TF)-hub genes, and drug-hub genes was also evaluated in this study. Results: After analysis, some genes with the highest degree of connectivity, which were involved in the pathogenesis of HELLP syndrome were identified, and they were known as hub genes. These genes are as follows: IFN-gamma CXCL1, CCL2, CCL3, TLR2, IL-1B, CXCL6, IL-6, CCL4, and CXCL2. has-mir-34a-5p, has-mir-20a-5p, and has-mir-27a-3p as miRNA, as well as RELA as TF had the most interaction with the hub genes. Conclusion: Finally, IL-6 and CXCL10 that were compared to the other hub genes had the highest interaction with other genes;therefore, their role in Shamgir's pathogenesis is significant. Targeting the cited genes would be a strategy to prevent symptom manifestation and better patient management.
ABSTRACT
Since the spread of the first cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection much progress has been made in understanding the disease process. However, we are still facing the complications of coronavirus disease 19 (COVID-19). Multiple sequelae may appear as a consequence of acute infection. This set of entities called post-COVID-19 syndrome involves a wide variety of new, recurrent or persistent symptoms grouped together as a consequence of the acute disease process. One of those that has attracted the most attention is the liver and bile duct involvement called post-COVID-19 cholangiopathy. This is characterized by elevation of liver markers such as alkaline phosphatase, bilirubin and transaminases as well as alterations in the bile ducts in imaging studies. Thus, a narrative review of the cases reported until the end of 2021 was carried out. From the findings found, we concluded that patients who have had COVID-19 or during the process have required hospitalization should remain under follow-up for at least 6 months by a multidisciplinary team.
ABSTRACT
Case Presentation: A 10 year old male with prior COVID-19 exposure presented with 7 days of fever, rash, cough, vomiting, and hypotension. Laboratory evaluation was notable for SARS-CoV2 antibodies, elevated cardiac enzymes, BNP, and inflammatory markers. Initial echocardiogram showed normal cardiac function and a small LAD coronary aneurysm. He was diagnosed with Multisystemic Inflammatory Syndrome in Children (MIS-C) and given methylprednisolone and IVIG. Within 24 hours, he developed severe LV dysfunction and progressive cardiorespiratory failure requiring VA-ECMO cannulation and anticoagulation with bivalirudin. Cardiac biopsy demonstrated lymphocytic infiltration consistent with myocarditis. On VA-ECMO, he had transient periods of complete AV block. With immunomodulator treatment (anakinra, infliximab) and 5 days of plasmapheresis, inflammatory symptoms and cardiac function improved. He weaned off ECMO, and anticoagulation was transitioned to enoxaparin. He had left sided weakness 5 days later, and brain MRI revealed an MCA infarct. Ten days later, he had focal right sided weakness and repeat MRI showed multiple hemorrhagic cortical lesions, thought to be thromboembolic with hemorrhagic conversion secondary to an exaggerated inflammatory response to an MSSA bacteremia in the setting of MIS-C. Enoxaparin was discontinued. After continued recovery and a slow anakinra and steroid wean, he has normal coronary arteries, cardiac function, and baseline ECG but requires ongoing neurorehabilitation. Discussion(s): COVID-19 infection in children is often mild, but MIS-C is an evolving entity that can present with a wide range of features and severity. This case highlights two concepts. While first degree AV block is often reported in MIS-C, there is potential for progression to advanced AV block. Close telemetry monitoring is critical, especially if there is evidence of myocarditis. MIS-C shares features with Kawasaki disease, with a notable difference being a higher likelihood of shock and cardiac dysfunction in MIS-C. In MIS-C patients with cardiovascular collapse requiring ECMO, there is a risk for stroke. There should be a low threshold for neuroimaging and multidisciplinary effort to guide anticoagulation in these complex cases.
ABSTRACT
The pandemic of coronavirus infection is characterized by a low percentage of complications and severe forms in sick children compared to the adult population. However, there have been described cases of severe clinical course of COVID-19 in children with comorbidities among which is obesity. The aim of this study was to analyze the severe course of a new coronavirus infection paralleled with morbid obesity in a pediatric patient. Materials and methods. All accompanying patient medical documentation was examined. Results and discussion. From the anamnesis of life it is known that the patient was long time complained of intensively increased body weight, on which she repeatedly underwent examinations. In 2018, hypothalamic pubertal syndrome was diagnosed for the first time, for which the patient received hypoglycemic and antihypertensive drugs, hepatoprotectors on an ongoing basis. In the epidemiological anamnesis, the intrafamilial COVID-19 contact with mother was established. The main disease began acutely with a rise in body temperature up to 39-39.5degreeC, cough and weakness. During the first week of illness, the patient did not seek medical help and receive self-treatment, but the positive effect was not achieved. Saturation measurement showed low oxygen level (SpO2 71%). In this regard, the patient underwent chest computed tomography, which revealed a bilateral interstitial polysegmental lung lesion with signs of consolidation. After emergency hospitalization, the patient was prescribed empiric antibiotic therapy, anti-inflammatory and antithrombotic treatment, as well as respiratory support. A positive PCR result of a throat and nasal swab for SARS-CoV-2 was obtained in the hospital. Due to a poor response to therapy, the patient was transferred to a respiratory hospital. At the time of hospitalization, the condition was considered severe due to severe respiratory failure and premorbidity. The range of treatments included oxygenotherapy, antibacterial and anticoagulation therapy, as well as surfactant and the nucleoside analogue Remdesivir. During treatment, the clinical picture gained a positive trend, and after 6 days of hospitalization the patient no longer needed respiratory support. According to the results of repeated computed tomography, bilateral interstitial polysegmental pneumonia was diagnosed with damage to the lung tissue up to 95%. The patient remained stable and showed no signs of respiratory failure during the following days of hospitalization. On the 20th day of ilness, the patient was discharged from hospital with full clinical recovery. Conclusion. This clinical case demonstrates the role of premorbid background in aggravating the clinical picture of a new coronavirus infection in a child. Careful study of anamnestic characteristics is necessary in patients of any age, even with an uncomplicated disease course.Copyright © 2023 Saint Petersburg Pasteur Institute. All rights reserved.
