ABSTRACT

Introduction: The use of protective mechanical ventilation and prone position was recommended for the management of moderate to severe acute respiratory distress syndrome (ARDS) due to COVID-19, as a result of its reported utility on oxygenation and mortality. Our objective is to describe gasometric and mechanical behavior in subjects with ARDS due to COVID-19 managed with protective mechanical ventilation and prone position in a high complexity hospital. Method: Observational study. Subjects ≥18 years of age with ARDS due to COVID-19 were included. Protective mechanical ventilation was started from the first connection to invasive ventilation, while the prone position started with PaO2/FIO2 150. Follow-up was performed during and after the prone position. A descriptive analysis of baseline characteristics and comparison of means between groups was performed using the Dunn and Friedman test. Statistical significance corresponds to p 0.05 in all analyses. Results: 74 subjects were studied, 58% correspond to men with a mean age of 60 years. There is evidence of a significant increase in arterial oxygenation assessed by PaO2 (76 to 98 mmHg, p 0.05) and PaO2/FIO2 (100 to 161, p 0.05) during the first hour of treatment, with stability of values beyond 48 hours after supination. Pulmonary mechanics values remain constant within the established protection range (p = 0,18). Conclusion: The strategy of protective mechanical ventilation and prone position for 48 or more hours, in subjects with moderate to severe ARDS due to COVID-19, improves and maintains arterial oxygenation up to 48 hours after supination. © 2023

ABSTRACT

The respiratory pump that provides pulmonary ventilation includes the respiratory center, peripheral nervous system, chest and respiratory muscles. The aim of this study was to evaluate the activity of the respiratory center and the respiratory muscles strength after COVID-19 (COronaVIrus Disease 2019). Methods. The observational retrospective cross-sectional study included 74 post-COVID-19 patients (56 (76%) men, median age - 48 years). Spirometry, body plethysmography, measurement of lung diffusing capacity (DLCO), maximal inspiratory and expiratory pressures (MIP and MEP), and airway occlusion pressure after 0.1 sec (P0.1) were performed. In addition, dyspnea was assessed in 31 patients using the mMRC scale and muscle strength was assessed in 27 of those patients using MRC Weakness scale. Results. The median time from the COVID-19 onset to pulmonary function tests (PFTs) was 120 days. The total sample was divided into 2 subgroups: 1 - P0.1 <= 0.15 kPa (norm), 2 - > 0.15 kPa. The lung volumes, airway resistance, MIP, and MEP were within normal values in most patients, whereas DLCO was reduced in 59% of cases in both the total sample and the subgroups. Mild dyspnea and a slight decrease in muscle strength were also detected. Statistically significant differences between the subgroups were found in the lung volumes (lower) and airway resistance (higher) in subgroup 2. Correlation analysis revealed moderate negative correlations between P0.1 and ventilation parameters. Conclusion. Measurement of P0.1 is a simple and non-invasive method for assessing pulmonary function. In our study, an increase in P0.1 was detected in 45% of post-COVID-19 cases, possibly due to impaired pulmonary mechanics despite the preserved pulmonary ventilation as well as normal MIP and MEP values.Copyright © Savushkina O.I. et al., 2023.

ABSTRACT

During the early period of COVID-19 pandemic, there was a serious shortage of personal protective equipments (PPEs), which caused difficulty in homecare agencies to make home visits to those (possible) positive COVID-19 cases. An organization with the help of several foundations started a special program to distribute PPEs to those agencies in which there was a possible case or those cases that had close contact with the positive cases. This study examined whether this voluntary activity contributed to increasing the sense of security in providing care among homecare workers. We conducted a survey with homecare agencies that received PPEs from the program between July 2020 and February 2021. The participants were agency managers who applied for PPEs. We conducted the survey twice, before and after receiving PPEs. In the questionnaire, we asked about the overall sense of security in providing care for those infected with COVID-19, reasons for applying for PPE, symptoms of the client or his/her family who caused the PPE request, and the agency's and clients' characteristics. We analyzed the data from 802 responses. Before PPE distribution, the sense of security was associated with the focal client having a cognitive impairment (β = −0.096), having cough (β = −0.088), fatigue (β = −0.085), or headache (β = −0.078). Agencies that did not visits those (possibly) positive cases (β = −0.123) had lower sense of security. Overall, the mean sense of security increased after receiving PPE. Factors that contributed to the increase in sense of security included a lower sense of security before the application (β = −0.529), visiting clients without dyspnoea (β = −0.109), the agency that did not visit positive cases before the application (β = −0.089), and with higher satisfaction with the days of PPEs received (β = 0.144). These results underline the benefit of the special PPsE distribution program.

ABSTRACT

BackgroundCOVID-19 is associated with higher morbidity and mortality burdens in immunocompromised individuals, including patients with systemic lupus erythematosus (SLE;1). These patients might benefit from treatment with anti-SARS-CoV-2-specific antiviral agents and monoclonal antibodies, but clinical evidence is to date limited.Objectivesto comparatively assess the course of COVID-19 in patients with SLE treated or untreated with COVID-19-specific agents.MethodsPatients with SLE and COVID-19 treated with antivirals and/or monoclonal antibodies from February 2020 to December 2022 were identified within a three-centre cohort of tertiary referral centres and age-, sex- SLE extension- and SLE duration-matched 1:2 with patients with a history of untreated COVID-19. Data on COVID-19 presentation, course (including time to viral clearance) and sequelae, along with SLE treatment at COVID-19 onset and SLE course after COVID-19 were collected. COVID-19 severity at presentation was quantitated through a 0-4 analogue scale [2]. Data are expressed as median (interquartile range, IQR) unless otherwise specified.ResultsOver three years, 39% of patients with SLE had at least one COVID-19 event. Eighteen subjects (16 women) were treated with antivirals (n=12) or monoclonal antibodies (n=6) and were matched with 36 controls. There was no difference in the frequency of organ involvement between the two groups. Treated patients were receiving significantly higher prednisone daily doses at COVID-19 onset (6.25 (0-10) vs 0 (0-2.5) mg;p=0.005) and had a higher prevalence of previous high-dose steroid treatments (83% vs 47%;p=0.019) compared to controls. SLE disease activity index (3 (0-5) vs 1 (0-4)) and SLE International Collaborating Clinics Damage Index scores (1 (0-3) vs 0 (0-1)) were also numerically higher in treated patients at COVID-19 onset. Patients in the treated group had more severe COVID-19 at presentation but showed no significant differences with control subjects in terms of COVID-19 resolution, prevalence of sequelae and viral clearance (Table 1). There was also no difference in flare occurrence between the two groups (Log-rank=0.02, p=0.889). Two patients reported mild adverse events with monoclonal antibodies (muscle cramps and chest pain, both self-resolving).ConclusionThese data support the safe use of COVID-19 specific treatments in patients with SLE. Patients treated with antivirals and monoclonal antibodies had a favourable COVID-19 course, despite a more severe presentation and a higher risk of deterioration due to SLE and corticosteroid treatment burden, suggesting the potential efficacy of COVID-specific treatments in preventing severe COVID-19 in patients with SLE.References[1]Strangfeld A et al, Ann Rheum Dis, 2021[2]World Health Organization.

ABSTRACT

The COVID-19 epidemic required rapid and frequent adaptations from the prehospital emergency medical services (EMS). The exposure of EMS providers is significant, particularly during procedures at risk of aerosolization such as advanced airways management or cardiopulmonary resuscitation. EMS personal need to be equipped with appropriate personal protective equipment and trained in its use. Interhospital transfers from COVID-19 patients are complex and involve mainly intubated patients. The possible shortage of resources may motivate the implementation of dedicated prehospital triage and orientation recommendations, which should be consistent with the hospital processes.Copyright © 2020 Editions Medecine et Hygiene.

ABSTRACT

BackgroundSome individuals may have persistent symptoms after COVID-19, a new condition known as long COVID-19. However, these complaints can be misunderstood with disease activity in patients with immune-mediated rheumatic diseases (IMRD), especially fatigue and mental distress.ObjectivesTo evaluate fatigue, depression, anxiety, and stress in IMRD patients after 6 months of COVID-19, compared with IMRD patients without COVID-19.MethodsThe ReumaCoV Brasil is a longitudinal study designed to follow-up IMRD patients for 6 months after COVID-19 diagnosis (cases) compared with IMRD patients no COVID-19 (controls). Clinical data, such as age, sex, comorbidities, as well as disease activity measurements and current treatment regarding IMRD, and COVID-19 outcomes were evaluated in all patients. The FACIT questionnaire (Functional Assessment of Chronic Illness Therapy) and the DASS 21 (Depression, Anxiety and Stress Scale - 21 Items) were applied at 6 months after COVID in both groups.ResultsA total of 606 IMRD patients were included, of whom 322 (53.1%) cases and 284 (46.9%) controls. Most patients were female (85.3%) with mean age 46.1 (13.0) years old. Specific disease activity were similar between cases and controls. There was a significant difference between FACIT scores and 3 domains of DASS-21 comparing cases and controls (Figure 1). The factors associated with FACIT were female gender, diabetes, obesity, no comorbidities, COVID manifestations (skin, joint pain, asthenia, diarrhea, and dyspnea), and chronic oral corticosteroid use. DASS-21 Depression was associated with these same factors. Female gender, COVID manifestations as skin, joint pain, asthenia, cough, dyspnea, and chronic oral corticosteroid use were associated with DASS-21-Anxiety. DASS-21 Stress was associated with female gender, asthenia, diarrhea, dyspnea, cough, chronic oral corticosteroid use, and hospitalization. Table 1 shows the variables that remained in the models after the univariate logistic analysis. A weak correlation between disease activity and FACIT was observed in rheumatoid arthritis (p=0.010;r2 = 0.035) and ankylosing spondylitis patients (p=0.010;r2 = 0.129). No other correlations were observed between the scores results and disease activity (patient's global assessment - PGA), medications or specific IMRD.ConclusionFatigue and mental changes such as depression, anxiety, and stress, occurred more frequently in IMRD patients who had COVID-19 than in those who did not have COVID-19, especially in women, regardless of disease activity score. Fatigue was more related to female gender, diabetes, obesity, and current joint pain. Mental impairment was more associated with severity of COVID-19, including respiratory and non-respiratory symptoms.Figure 1.Comparison between cases and controls of FACIT and DASS-21 depression, anxiety, and stress scoresFACIT (Functional Assessment of Chronic Illness Therapy);DASS-21 (Depression, Anxiety and Stress Scale - 21 Items):Table 1.Final model using binary Logistic Regression analysis to evaluate the preditive factors associated with FACIT and DASS-21 scoresFACIT Score ≤ 37 x score > 37§DASS-21-DEPRESSION Score ≤ 6 (normal/mild) x score > 6 (moderate/severeDASS-21-ANXIETY Score ≤ 5 (normal/mild) x score > 5 (moderate/severe)DASS-21-STRESS Score ≤ 9 (normal/mild) x score > 9 (moderate/severeVariableP-valueOR (CI 95%)VariableP-valueOR (CI 95%)VariableP-valueOR (CI 95%)VariableP-valueOR (CI 95%)Female0.151.83 (1.12-2.98)No comorbidities0.0290.66 (0.46-0.95)Joint pain0.0022.44 (1.39-4.26)Female0.0122.31 (1.20-4.46)Diabetes0.0062.35 (1.28-4.32)Joint pain**0.0012.58 (1.57-4.22)Dyspnea0.0013.61 (2.11-6.19)Dyspnea0.0013.69 (2.09-6.51)Dyspneia0.0012.00 (1.23-3.26)Dyspnea0.0012.82 (1.79-4.44)Oral CE0.0141.55 (1.09-2.21)Joint pain0.0052.20 (1.41-3.43)Oral CE0.0481.41 (1.00-1.99)§Lower scores mean worse fatigue;CE: corticosteroid;OR: odds ratio;CI: confiance intervalAcknowledgementsReumaCoV Brasil researchers, Brazilian Rheumatology Society and National Council for Scientific and Technological Deve opment.Disclosure of InterestsNone Declared.

ABSTRACT

Introduction:Non-invasive mechanical ventilation is a ventilatory alternative for COVID-19 cases. Background:To describe the characteristics and evolution of non-invasive mechanical ventilation (NIMV) in patients discharged from Provisional Center for moderate COVID-19 patients in Figali, Panama. Methods:A descriptive, retrospective, longitudinal stu was carried out in all adult patients discharged from June to July 2021 and who received non-invasive mechanical ventilation. A questionnaire was used using the digital individual medical record as primary source. Descriptive statistics techniques were used. Results:35.9% of the patients (78/217) who were admitted required non-invasive mechanical ventilation on the ninth day of symptoms and the second day after admission. 62.8% (49/78) were obese and 29.5% (23/78) hypertensive. The respiratory rate 30 and the decrease in the PaO2/FiO2 ratio decided the begining of non-invasive mechanical ventilation in 56.4% (78/217) of those admitted. 62.8% (49/78) had moderate-severe acute respiratory distress syndrome, and the severity was related to ventilation failure out of the total number of ventilated patients. Ventilation was successful in 65.4% (51/78). PaO2/FiO2 <150 (62.9%), respiratory rate 30 (55.6%) and physical exhaustion (51.85%) decided ventilation failure. Conclusions:Non-invasive mechanical ventilation is an effective procedure in COVID-19 patients and moderate or severe respiratory distress;although its success is related to the less severe forms. Low PaO2/FiO2, together with symptoms, were key indicators to assess the begining, success or failure of NIMV;not so the values of PaO2, PaCO2 and SpO2.

ABSTRACT

BackgroundCOVID-19 has shaped the world over the last 3 years. Although the risk for severe COVID-19 progression in children is low it might be aggravated by chronic rheumatic disease or treatment with immunosuppressive drugs.ObjectivesWe analyzed clinical data of COVID-19 cases among paediatric patients with rheumatic diseases reported to BIKER between March 2020 and December 2022.MethodsThe main task of the German BIKER (Biologics in Pediatric Rheumatology) registry is safety monitoring of biologic therapies in JIA. After the onset of the COVID-19 pandemic, the survey was expanded with a standardized form to proactively interview all participating centers about occurrence, presentation and outcome of SARS-CoV-2 infections in children with rheumatic diseases.ResultsA total of 68 centres participated in the survey. Clinical data from 928 COVID infections in 885 patients with rheumatic diseases could be analyzed. JIA was the most common diagnosis with (717 infections), followed by genetic autoinflammation (103 infections), systemic autoimmune diseases (78 infections), idiopathic uveitis (n=25), vasculitis (n=5).In 374 reported COVID infections (40%), patients were receiving conventional DMARDs, in 331 (36%) biologics, mainly TNF inhibitors (TNFi, n=241 (26%)). In 567 reports (61%) patients used either a biologic or a DMARD, in 339 reports patients (37%) did not use any antirheumatic medication including steroid.Over the last 3 years, COVID-19 occurred in Germany in 5 distinguishable waves, calendar weeks (CW) 10-30 in 2020, CW 21/2020 – 8/2021(both predominantly wild-type variant), CW 9-27 in 2021 (Alpha variant in the majority of infections), CW 28-51 in 2021 (Delta variant), since CW 52/2021 (several Omikron variants;Robert-Koch Institute: VOC_VOI_Tabelle.xlsx;live.com))In our cohort, patients with SARS-CoV-2 infection were slightly older during the 1st and 2nd wave (mean age 12.7+/-3.5 and 12.8+/-4.3 years) compared to the 4th and 5th wave with 11.4+/-3.9 and 11.4+/-4.2 years;p=0.01.160 asymptomatic SARS-CoV-2 infections were reported, frequencies of symptoms associated with COVID-19 are shown in table 1.Five patients were hospitalized for 4-7 days. A 3½-year-old female patient succumbed during the first wave with encephalopathy and respiratory failure. The patient had been treated with MTX and steroids for systemic JIA. Genetic testing revealed a congenital immunodeficiency. No other patient needed ventilation or intensive care. One case of uncomplicated PIMS in an MTX treated JIA patient was reported.The duration of SARS-CoV-2 infection-associated symptoms was markably shorter during the 5th wave with 6.7+/-5.1 days, compared with reports from the other 4 waves (Table1).The duration of symptoms was higher in MTX treated patients (10.2+/-8.4 days) compared to patients without treatment (7.7+/-10.8;p=0.004) or patients treated with TNFi (8.2+/-4.8, p=0.002). Although patients treated with steroids also had a longer duration of symptoms (9.7+/-7.0), this was not significant.ConclusionExcept for one patient with congenital immunodeficiency who died, no case of severe COVID-19 was reported in our cohort. At the time of infection, over 60% of patients had been treated with conventional DMARDs and/or biologics. Although MTX treated patients had a slightly longer duration of symptoms, antirheumatic treatment did not appear to have a negative impact on severity or outcome of SARS-CoV-2 infection.Table 1.Characteristics and frequency of symptoms in SARS-CoV-2 infectionsN or mean (SD)1st wave N=202nd wave N=843rd wave N=384th wave N=1245th wave N=662female14532775432age at COVID-19, years12.7 (3.5)12.8 (4.3)11.8 (3.5)11.4 (3.9)11.4 (4.2)asymptomatic126132694duration of symptoms;days,11.9 (14.7)9.2 (7.0)14.1 (11.6)10.3 (7.6)6.7 (5.1)fever1218541306cough1015652245rhinitis5261344289headache4161227171sore throat61139132musculosceletal pain2751348loss of smell/taste71162113fatigue4882680dizziness122116gastrointestinal symptoms151864dyspnea1117pneumonia11bronchitis1REFERENCES:NIL.Acknowledgements:NIL.Disclosure of Inter stsAriane Klein Speakers bureau: Novartis, Toni Hospach Speakers bureau: Speaking fee Novartis and SOBI., Frank Dressler Speakers bureau: Abbvie, Novartis, Pfizer, Advisory Boards Novartis and Mylan, Daniel Windschall Grant/research support from: research funds by Novartis, Roche, Pfizer, Abbvie, Markus Hufnagel: None declared, Wolfgang Emminger: None declared, Sonja Mrusek: None declared, Peggy Ruehmer: None declared, Alexander Kühn: None declared, Philipp Bismarck: None declared, Maria Haller: None declared, Gerd Horneff Speakers bureau: Pfizer, Roche, MSD, Sobi, GSK, Sanofi, AbbVie, Chugai, Bayer, Novartis, Grant/research support from: Pfizer, Roche, MSD, AbbVie, Chugai, Novartis.

ABSTRACT

IntroductionHeart Failure (HF) carries significant mortality and morbidity, especially due to comorbidities such as Atrial Fibrillation (AF). Previous work illustrates that mitochondrial dysfunction underpins the pathophysiology of both HF and AF, including decreased Adenosine TriPhosphate (ATP) production, Ca2+ mishandling, oxidative stress and elevated apoptosis. In addition to these problems, recent work suggests the Mitochondrial Permeability Transition Pore (MPTP) in ventricular cardiomyocytes may become sensitised to Ca2+ during HF, leading to increased apoptosis. Nevertheless, the role of mitochondrial dysfunction has not been investigated in the atria. In this study, we investigated the role of Ca2+ sensitivity of the MPTP and mitochondrial aerobic capacity in atrial muscle of the failing heart.MethodsRight atrial appendage and right ventricular free wall were dissected from 15 sheep representing an ovine model of tachycardia-induced HF. The tissue was subsequently homogenized and differentially centrifuged, yielding isolated mitochondria. Respiratory function was measured using a respirometer, with the electron transport system (ETS) selectively probed through addition of various substrates stimulating differing ETS complexes. A Calcium Retention Capacity (CRC) assay determined MPTP Ca2+ sensitivity, which involved Ca2+ titrations onto isolated mitochondria containing a Ca2+-sensitive fluorescent dye. An increase in fluorescence marked MPTP opening.ResultsAerobic capacity was not affected by HF, but an increase in ventricular leak respiration was statistically significant (p=0.0140). HF reduced atrial mitochondrial efficiency by 68% (p=0.0063) but did not affect maximal mitochondrial respiration. There was no significant effect of HF or tissue-type on MPTP Ca2+ sensitivity and mitochondrial Ca2+ buffering capacity.ConclusionOur data suggests HF affects atrial and ventricular mitochondrial respiratory function asymmetrically, with HF affecting atrial mitochondrial efficiency and ventricular leak respiration. The COVID-19 pandemic hindered this research project;however, it provides rationale on the unequal effect of HF on mitochondrial function across the atria and ventricle. Future research should therefore consider incorporating atrial samples when assessing potential HF therapies.Conflict of InterestNil

ABSTRACT

BackgroundPatients with rheumatic diseases may present more severe SARS-CoV-2 infection compared to the general population. However, in some studies, hospitalization and mortality due COVID-19 were lower in patients with axial spondyloarthritis (axSpA) compared to other rheumatic diseases.ObjectivesTo assess the severity of SARS-CoV-2 infection in patients with axSpA from the SAR-COVID registry, comparing them with patients with rheumatoid arthritis (RA), and to determine the factors associated with poor outcomes and death.MethodsPatients ≥18 years old from the SAR-COVID national registry with diagnosis of AxSpA (ASAS criteria 2009) and RA (ACR/EULAR criteria 2010) who had confirmed SARS-CoV-2 infection (RT-PCR or positive serology), recruited from August 2020 to June 2022 were included. Sociodemographic and clinical data, comorbidities, treatments and outcomes of the infection were collected. Infection severity was assessed using the WHO-ordinal scale (WHO-OS)[1]: ambulatory [1], mild hospitalizations (2.3 y 4), severe hospitalizations (5.6 y 7) and death [8].Statistical analysisDescriptive statistics. Chi[2] or Fischer test and Student T or Mann-Whitney as appropriate. Poisson generalized linear model.ResultsA total of 1226 patients were included, 59 (4.8%) with axSpA and 1167 (95.2%) with RA. RA patients were significantly older, more frequently female, and had a longer disease duration. More than a third of the patients were in remission. 43.9 % presented comorbidities, arterial hypertension being the most frequent. At the time of SARS-Cov-2 diagnosis, patients with RA used glucocorticoids and conventional DMARDs more frequently than those with axSpA, while 74.6% of the latter were under treatment with biological DMARDs being anti-TNF the most used (61%).94.9 % of the patients in both groups reported symptoms related to SARS-CoV-2 infection. Although the differences were not significant, patients with RA presented more frequently cough, dyspnea, and gastrointestinal symptoms, while those with axSpA reported more frequently odynophagia, anosmia, and dysgeusia. During the SARS-CoV-2 infection, 6.8% and 23.5% of the patients with axSpA and RA were hospitalized, respectively. All of the patients with axSpA were admitted to the general ward, while 26.6% of those with RA to intensive care units. No patient with axSpA had complications or severe COVID-19 (WHO-OS>=5) or died as a result of the infection while mortality in the RA group was 3.3% (Figure 1).In the multivariate analysis adjusted to poor prognosis factors, no association was found between the diagnosis of axSpA and severity of SARS-CoV-2 infection assessed with the WHO-OS (OR -0.18, IC 95%(-0.38, 0.01, p=0.074).ConclusionPatients with EspAax did not present complications from SARS-CoV-2 infections and none of them died due COVID-19.Reference[1]World Health Organization coronavirus disease (COVID-19) Therapeutic Trial Synopsis Draft 2020.Figure 1.Outcomes and severity of SARS-CoV-2 infection in patients with axSpA and RA.[Figure omitted.

ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19) patients with acute respiratory failure who experience delayed initiation of invasive mechanical ventilation have poor outcomes. The lack of objective measures to define the timing of intubation is an area of concern. We investigated the effect of timing of intubation based on respiratory rate-oxygenation (ROX) index on the outcomes of COVID-19 pneumonia. METHODS: This was a retrospective cross-sectional study performed in a tertiary care teaching hospital in Kerala, India. Patients with COVID-19 pneumonia who were intubated were grouped into early intubation (within 12 hours of ROX index <4.88) or delayed intubation (12 hours or more hours after ROX <4.88). RESULTS: A total of 58 patients was included in the study after exclusions. Among them, 20 patients were intubated early, and 38 patients were intubated 12 hours after ROX index <4.88. The mean age of the study population was 57±14 years, and 55.0% of the patients were male; diabetes mellitus (48.3%) and hypertension (50.0%) were the most common comorbidities. The early intubation group had 88.2% successful extubation, while only 11.8% of the delayed group had successful extubation (P<0.001). Survival was also significantly more frequent in the early intubation group. CONCLUSIONS: Early intubation within 12 hours of ROX index <4.88 was associated with improved extubation and survival in patients with COVID-19 pneumonia.

ABSTRACT

Introduction: Although, several vaccines are being approved, no effective antiviral drug has been developed for COVID-19 infectious. The present investigation was aimed to increase the essential oils of Cuscuta campestris using far-red light treatment and examine the potential of crude extracts of C. campestris against selected pneumonia pathogens and COVID-19.Methods: Anti-COVID-19 activity was determined in human lung cell lines and COVID-19 positive patients.Results: Results demonstrated that the aqueous extract had the highest amount of anti-COVID-19, antibiotic and antioxidant activity. The far-red light treatment increased Scoparone, cineole, Benzofuran, 2, 3- dihydro, Cinnamic acid, and Benzo[h]quinoline, 2, 4-dimethyl, which are mainly effective components against COVID-19 inflammation and pneumonia microbes. CT scan and clinical laboratory tests in a clinical case study, a 30-year-old woman who presented with severe 2019-nCoV, demonstrated that inhalation of 30 mg extract nebulized/day for seven days resulted in significant improvement in consolidation and ground-glass opacity in lungs on the seventh day of treatment.Conclusion: It is hoped that this study leads to the introduction of some compounds that could be used to formulate new and more potent anti-COVID-19 antibiotics, or other drugs of natural origin in medicine.

ABSTRACT

The pandemic of coronavirus disease 2019 (COVID-19) has spread worldwide and the mortality is high in severe COVID-19 patients. Clinical studies suggested that obesity is an independent risk factor for severe and dead cases of COVID-19. For COVID-19 patients with obesity, early evaluation of obesity-related comorbidities and aggressive treatments, including diet control, airway management, anticoagulant thromboprophylaxis, and management of comorbidities, are encouraged to improve their prognosis.Copyright © 2021, Peking Union Medical College Hospital.

ABSTRACT

The respiratory pump that provides pulmonary ventilation includes the respiratory center, peripheral nervous system, chest and respiratory muscles. The aim of this study was to evaluate the activity of the respiratory center and the respiratory muscles strength after COVID-19 (COronaVIrus Disease 2019). Methods. The observational retrospective cross-sectional study included 74 post-COVID-19 patients (56 (76%) men, median age - 48 years). Spirometry, body plethysmography, measurement of lung diffusing capacity (DLCO), maximal inspiratory and expiratory pressures (MIP and MEP), and airway occlusion pressure after 0.1 sec (P0.1) were performed. In addition, dyspnea was assessed in 31 patients using the mMRC scale and muscle strength was assessed in 27 of those patients using MRC Weakness scale. Results. The median time from the COVID-19 onset to pulmonary function tests (PFTs) was 120 days. The total sample was divided into 2 subgroups: 1 - P0.1 <= 0.15 kPa (norm), 2 - > 0.15 kPa. The lung volumes, airway resistance, MIP, and MEP were within normal values in most patients, whereas DLCO was reduced in 59% of cases in both the total sample and the subgroups. Mild dyspnea and a slight decrease in muscle strength were also detected. Statistically significant differences between the subgroups were found in the lung volumes (lower) and airway resistance (higher) in subgroup 2. Correlation analysis revealed moderate negative correlations between P0.1 and ventilation parameters. Conclusion. Measurement of P0.1 is a simple and non-invasive method for assessing pulmonary function. In our study, an increase in P0.1 was detected in 45% of post-COVID-19 cases, possibly due to impaired pulmonary mechanics despite the preserved pulmonary ventilation as well as normal MIP and MEP values.Copyright © Savushkina O.I. et al., 2023.

ABSTRACT

Introduction: The debate about optimal management of patients with COVID-19 ARDS remains, including medical treatment, ventilatory strategies, awake proning and others. COVIP is a multicentric observational study with over 3000 patients under NIV. A substudy by Polok and al. evaluated patients (PTS) >= 70 years old. At our intermediate care unit (IU) we used a strategy of high dose corticosteroid started when the work of breathing (WOB) increased, prolonged awake prone positioning (> 12 h) and high CPAP ventilatory strategy. We describe our cohort of >= 70 years old NIV PTS and compare it to COVIP substudy results. Method(s): Descriptive retrospective study. Data were collected from electronic medical records of 95 COVID-19 PTS aged 70 years old or above under NIV at the IU between September/20 and March/21. Categorical data are presented as frequency (percentage) and were compared using chi2-test. Continuous variables were compared using Mann-Whitney U test. Cohort results were compared with those from Polok et al. COVIP substudy (COVIPss). Result(s): 95 of PTS were submitted to NIV. Median age was 76 years and 49.5% were male, versus 75.7 and 71.4% in COVIPss. Median admission SOFA score was 4 and CFS was 3 with 14% considered frail (CFS > 5). In COVIPss median SOFA was 5 and 17% of PTS were frail. The preferred mode was CPAP with median maximum pressure of 13. Mean PaO2/fiO2 ratio after start of NIV was 125, 30% < 100. NIV failure occurred in 46.3% versus 74,7% in COVIPss. Our intra-unit mortality was 31.6%. 14 PTS (14.7%) were submitted to invasive mechanical ventilation and 57% of those died. In COVIPss mortality at 30d was 52.9% in NIV and 47.7 in IMV groups. Conclusion(s): We argue that NIV is a valid option for COVID ARDS management if supported by a multifaceted strategy such as ours, using prone and CPAP for WOB control. We agree with COVIPss authors as NIV trial should be short and intubation promptly if WOB not controlled. Comparison with COVIP substudy NIV failure and mortality results, support our belief.

ABSTRACT

Introduction: Coronavirus Disease 2019 (COVID-19), since its emergence, has spread rapidly as a pandemic causing massive loss of human life. This study aims to describe clinical severity of the disease in relation to age, mode of oxygen delivery and clinical outcome of patients admitted to a tertiary care center in Nepal. Methods: This was a descriptive cross-sectional study of data records of 130 COVID-19 patients 18 years and above admitted in Nepal Armed Police Force Hospital from April 2021 to June 2021 with Severe Acute Respiratory syndrome SARS-CoV-2 Reverse Transcriptase Polymerase Chain Reaction positive status. Ethical approval was obtained from Nepal Health research Council. Data were collected using structured proforma and analyzed using SPSS version 23. Results: Patients with severe illness (52/130) constituted 40% of the bulk of COVID-19 patients, 48 of them requiring intensive care. Among them, 38.5% required non-invasive ventilation and 32.7% were intubated during treatment. Severity of illness was variable among different age groups but mortality was high among severely ill patients, 19/52 (36.5%) and with increasing age. The overall mortality was 19/130 (14%) over the study period, all of which were among severely ill patients. Conclusions: Most of the clinically severe cases required Intensive Care Unit admission, the majority receiving oxygen therapy via non-invasive or invasive mechanical ventilation, with a high mortality rate. The number of severely ill COVID-19 patients was variable in different age groups. Mortality, however, was observed in severely ill patients only and proportionately increased in COVID-19 patients with advancing age.

ABSTRACT

Background: The mechanisms driving SARS-CoV-2 susceptibility remain poorly understood, especially the factors determining why a subset of unvaccinated individuals remain uninfected despite high-risk exposures. Method(s): We studied an exceptional group of unvaccinated healthcare workers heavily exposed to SARS-CoV-2 ('nonsusceptible') from April to June 2020, who were compared against 'susceptible' individuals to SARS-CoV-2, including uninfected subjects who became infected during the follow-up, and hospitalized patients with different disease severity providing samples at early disease stages. We analyzed plasma samples using different mass spectrometry technique and obtained metabolites and lipids profiles. Result(s): We found that the metabolite profiles were predictive of the selected study groups and identified lipids profiles and metabolites linked to SARS-CoV-2 susceptibility and COVID-19 severity. More importantly, we showed that non-susceptible individuals exhibited unique metabolomics and lipidomic patterns characterized by upregulation of most lipids -especially ceramides and sphingomyelin-and amino acids related to tricarboxylic acid cycle and mitochondrial metabolism, which could be interpreted as markers of low susceptibility to SARS-CoV-2 infection. Lipids and metabolites pathways analysis revealed that metabolites related to energy production, mitochondrial and tissue dysfunction, and lipids involved in membrane structure and virus infectivity were key markers of SARS-CoV-2 susceptibility. Conclusion(s): Lipid and metabolic profiles differ in 'nonsusceptible' compared to individuals susceptible to SARS-CoV-2. Our study suggests that lipid profiles are relevant actors during SARS-CoV-2 pathogenesis and highlight certain lipids relevant to understand SARS-CoV-2 pathogenesis. (Figure Presented).
