ABSTRACT
Objectives: Severe acute respiratory syndrome-coronavirus 2/COVID-19 infection is still a global concern, with pregnant women are considered as vulnerable population. Until now, the characteristics of pregnant women in Indonesia who are infected with COVID-19, as well as pregnancy and neonatal outcomes, are still unknown. This study aims to obtain national data, which are expected to be useful for the prevention and management of COVID-19 in pregnant women in Indonesia. Method(s): There were 1,427 patients recruited in this retrospective multicenter study. This study involved 11 hospitals in 10 provinces in Indonesia and was carried out using secondary patient data from April 2020 to July 2021. COVID-19 severity was differentiated into asymptomatic-to-mild symptoms and moderate-to-severe symptoms. The collected data include maternal characteristics, laboratory examinations, imaging, pregnancy outcomes, and neonatal outcomes. Result(s): Leukocyte, platelets, basophil, neutrophils segment, lymphocytes, monocytes, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, alanine aminotransferase (ALT), aspartate aminotransferase (AST), C-reactive protein (CRP), urea, and creatinine were found to be significantly associated with severity differences (p < 0.05). Moderate-severe symptoms of COVID-19 also shown to have suggestive pneumonia findings on chest X-ray findings. Patients with asymptomatic-to-mild symptoms had significantly (p < 0.001) higher recovery rate, shorter hospital stay, less intensive care unit (ICU) admission, and had more vaginal delivery. Neonates from mother with mild symptoms also had significantly (p < 0.001) higher survival rate, higher birth weight, and higher APGAR score. Conclusion(s): Several laboratory and radiology components, as well as maternal and neonatal outcomes are related to the severity of COVID-19 in pregnant women in Indonesia.Copyright © The Author(s). 2023.
ABSTRACT
COVID-19 is mainly a respiratory illness caused by the SARS-CoV-2 but can also lead to GI symptoms. The primary host receptor which mediates the mechanism as SARS-CoV-2 enters the cell is the ACE2 receptor. Therefore, GI symptoms can be common in COVID-19, and in some cases, they are the first manifestation even before fever and respiratory symptoms. In addition, the liver function tests alteration often is related to a worse prognosis. The exact incidence of GI symptoms is a matter of debate. Moreover, wide variation concerning GI symptoms frequency exists, but the predominant ones seem to be diarrhea, anorexia, nausea, vomiting, and abdominal pain or discomfort.This review summarizes the most relevant findings of COVID-19 on the digestive system, including the liver, biliary tract, pancreas, the most common GI symptoms, and the atypical clinical GI manifestations.Copyright © 2022 Sociedad Medica del Hospital General de Mexico.

ABSTRACT
Aim: While recent evidence describes atypical outcomes of coronavirus disease 2019 (COVID-19) in elderly patients, the frequency of delirium and associated outcomes in elderly patients with COVID-19 (coronavirus disease 2019) infection undergoing emergency surgery are not well defined. This study aims to determine the effect of COVID-19 on postoperative delirium and postoperative death in elderly patients undergoing emergency surgery. Material(s) and Method(s): This descriptive and cross-sectional study was conducted in general surgery, orthopedics, and cardiovascular surgery clinics of a public hospital, including 30 days of follow-up between April 1 and May 1, 2021. All patients who were admitted to these clinics for emergency surgery intervention on these dates constituted the study population, while a total of 140 patients aged >=65 years, who met the study criteria, formed the sample of the study. Descriptive Characteristics Form and Nursing Delirium Screening Scale (Nu-DESC) were used as data collection tools in the study. SPSS 25.0 statistical program was used for data analysis. Result(s): Thirty (42.85%) of the SARS-CoV-2 positive (n=70) patients developed delirium in the study. 12.9% (n=18) of the patients died within 30 days of follow-up after surgery. There were 30 (69.8) of 70 SARS-CoV-2 positive patients who developed delirium, and 12 patients (25.5) died after testing positive for COVID-19, with a mean of 8.08T1.56 days within 30 days of admission. Discussion(s): These findings may lead to a poor clinical prognosis for COVID-19 infection delirium and postoperative death in patients over 65 years of age undergoing emergency surgery.Copyright © 2023, Derman Medical Publishing.

ABSTRACT
Background and objective: Millions of people worldwide have died from COVID-19, which has caused the failure of the lungs and other organs. The research assessed biochemical anomalies in COVID-19 patients to comprehend the illness and its effect better. Study Design: Retrospective longitudinal cohort analysis Place of study: ABWA Medical College Faisalabad Methods: A total of 150 adult patients (n=150) who tested positive for COVID-19 via RT-PCR were included in the study. A Roche Diagnostics Cobas C501 used spectrophotometry to measure calcium, magnesium, phosphate, lactate dehydrogenase (LDH), urea, creatinine, ferritin, and chloride in the blood. A NOVA electrolytic analyzer used Ion-selective electrodes to measure sodium, chloride, potassium, and bicarbonate. Result(s): In the study, 33.6% of patients had elevated urea levels, and 22.4% had elevated creatinine levels. Furthermore, 88.8% of patients had elevated ferritin levels, and 93.5% had elevated LDH levels. After 44 weeks, there was a drop in sodium-containing electrolytes, with 9% of patients experiencing a decrease in sodium, 22.4% in potassium, 53.3% in bicarbonate, 48.6% in calcium, and 23.4% in phosphorus. These changes in electrolyte levels suggest a long-term trend in electrolyte depletion among the patient population. There was no significant difference in biochemical anomalies between age groups (p > 0.05). Conclusion(s): These results suggest that COVID-19 patients have lung illness and multi-organ involvement, which should be considered when managing these patients. These biochemical alterations warrant careful monitoring for organ failure by healthcare practitioners. More study is required to comprehend the processes causing these biochemical anomalies in COVID-19 patients.Copyright © 2023 Lahore Medical And Dental College. All rights reserved.
ABSTRACT
Background: At our hospital, people with COVID-19 (coronavirus disease 2019) had a high rate of pulmonary barotrauma. Therefore, the current study looked at barotrauma in COVID-19 patients getting invasive and non-invasive positive pressure ventilation to assess its prevalence, clinical results, and features. Methodology: Our retrospective cohort study comprised of adult COVID-19 pneumonia patients who visited our tertiary care hospital between April 2020 and September 2021 and developed barotrauma. Result(s): Sixty-eight patients were included in this study. Subcutaneous emphysema was the most frequent type of barotrauma, reported at 67.6%;pneumomediastinum, reported at 61.8%;pneumothorax, reported at 47.1%. The most frequent device associated with barotrauma was CPAP (51.5%). Among the 68 patients, 27.9% were discharged without supplemental oxygen, while 4.4% were discharged on oxygen. 76.5% of the patients expired because of COVID pneumonia and its complications. In addition, 38.2% of the patients required invasive mechanical breathing, and 77.9% of the patients were admitted to the ICU. Conclusion(s): Barotrauma in COVID-19 can pose a serious risk factor leading to mortality. Also, using CPAP was linked to a higher risk of barotrauma.Copyright © 2021 Muslim OT et al.
ABSTRACT
The new coronavirus was first reported in China and caused a widespread global outbreak of pneumonia that spread rapidly across this country and many other countries. Acute kidney injury is one of the important complications of COVID-19, which has been shown in some cases. Exploring the diagnostic features of biomarkers of kidney function in COVID-19 patients may lead to better patient management. We collected laboratory data from 206 people with confirmed COVID-19 disease and evaluated their renal biomarkers, Blood Urea Nitrogen (BUN), and creatinine. The age range of the patients was almost 62 years old. The mean age in the dead patients and recovered patients was 71 and 54 years old, respectively. The average LDH value was 755 U/L, and creatine phosphokinase (CPK) was 267 U/L in the patients. The average BUN was 59.1 U/L, and creatinine was 1.5 U/L in COVID-2019 patients. Among all 193 patients, laboratory results revealed that 163 (85.4%) patients had an elevated BUN level. Based on creatinine levels for total patients, laboratory results revealed that 49 (25.4%) patients had an elevated value. The average BUN value in dead patients was 85 mg/dL, while in recovered patients was 40.5 mg/dL (P<0.0001). Also, the average creatinine level in dead patients was 1.86 mg/dL, while in recovered patients was 1.24 mg/dL (P=0.0004). Inflammation following COVID-19 disease causes kidney damage and elevated urea and creatinine levels, which may increase the risk of death in these patients.Copyright © 2023 Tehran University of Medical Sciences.
ABSTRACT
Introduction: Midazolam based continuous iv sedation became again prominent during the COVID-19 pandemic. However, this sedation therapy is associated with a high incidence of benzodiazepine-related delirium and an increased number of days spent in coma. Given the high midazolam dose requirements in some patients and due to the renal clearance (CL) of the active metabolite 1-OH-midazolam-glucuronide (OHmidazolamGluc), ICU patients with COVID-19 and continuous renal replacement therapy (CRRT) may are at risk of prolonged sedation. Therefore, the aim of the study was to investigate the CL of midazolam and metabolites in 5 critically ill COVID-19 patients with CRRT. Method(s): Pre-filter blood samples and ultrafiltrate samples were collected simultaneously. Midazolam, 1-OH-midazolam (OHmidazolam) and OHmidazolamGluc plasma samples were analysed by an UPLCMS/ MS method. CL of midazolam and metabolites were calculated by the delivered renal dose and sieving (SC) coefficient. Subsequently, the CL and delivered renal dose were corrected for downtime therapy and filter integrity by a filter urea ratio. Result(s): We included 4 cases of CVVHD and 2 cases of CVVHDF. Midazolam, OHmidazolam and OHmidazolamGluc concentrations in mug/l ranged from 0 to 6070, 0 to 295 and 1727 to 39,000, respectively. SCs ranged from 0.02 to 0.03 for midazolam, 0.05 to 0.06 for OHmidazolam and 0.23-0.43 for OHmidazolamGluc. The CL in ml/min by the delivered renal dose was 0.82-1.67 for midazolam, 2.20-3.46 for OHmidazolam and 4.0-27.65 for OHmidazolamGluc. The CL in ml/min by the corrected renal dose was 0.68-1.50, 1.83-2.33 and 3.40-25.4, respectively. The urea ratios were 0.53 to 1.0. Conclusion(s): Midazolam and OHmidazolam are not removed efficiently by CRRT and OHmidazolamGluc approximately up to 43%. Type of CRRT, filter integrity and downtime of CRRT affect the CL of midazolam and metabolites. Our results have implications for more personalized titration of midazolam in COVID-19 patients with CRRT, mainly to avoid oversedation.
ABSTRACT
Introduction: Anakinra treatment is approved for the treatment of COVID-19 pneumonia in hospitalized adults in need of oxygen and at risk for progression into severe respiratory failure (SRF) defined as circulating concentrations of the biomarker suPAR (soluble urokinase plasminogen activator receptor) >= 6 ng/mL by the EMA and has been authorized for emergency use by FDA under an EUA [1]. This is based on the results of the randomized SAVE-MORE trial where suPAR >= 6 ng/ mL was used to select patients at risk for SRF [2]. The suPAR test is not commercially available in the USA and an alternative method of patient selection was needed. Method(s): In collaboration with the US FDA, an alternative method to select patients most likely to have suPAR >= 6 ng/mL based on commonly measured patient characteristics was developed. Patients with at least 3 of the following criteria are considered likely to have suPAR >= 6 ng/ ml: age >= 75 years, severe pneumonia by WHO criteria, current/previous smoking status, Sequential Organ Failure Assessment score >= 3, neutrophil-to-lymphocyte ratio >= 7, hemoglobin <= 10.5 g/dl, history of ischemic stroke, blood urea >= 50 mg/dl and/or history of renal disease. Result(s): The positive predictive value of this new score was 95.4% in SAVE-MORE population. However, a lower sensitivity meant a small proportion of patients with suPAR >= 6 ng/ml will not be identified by the new score. The adjusted hazard ratio for survival at 60 days for patients meeting this score and who receive anakinra is 0.45 (Fig. 1). Conclusion(s): The developed score predicts accurately patients with suPAR levels >= 6 ng/mL and may be used as an alternative to guide anakinra treatment in patients with COVID-19 pneumonia. Based on these subgroup results, patients in SAVE-MORE who met the new score appeared to show beneficial efficacy results with treatment of anakinra consistent with the overall studied population.
ABSTRACT
The aim is to examine dynamics of avidity maturation of IgG antibodies against SARS-CoV-2 RBD depending on the type of immunization (vaccination or infection), as well as on the duration and frequency of immunization. Materials and methods. The study was performed on two sample cohorts collected at two time points during COVID-19 pandemic. The first cohort (group No. 1) consisted of 87 samples of blood sera obtained from COVID-19 convalescents in the period from March to September 2020. The second cohort included 204 samples obtained in September 2021 from two patient groups. Group No. 2 (n = 64) - patients immunized with a full course of Gam-Covid-Vac, group No. 3 (n = 140) - COVID-19 convalescent patients and subjects vaccinated with Gam-Covid-Vac ("hybrid immunity"). Results and conclusion. The dynamics of avidity maturation for SARS-CoV-2 RBD IgG antibodies depending on the method and frequency of immunization, showed that the most effective immunity was formed in COVID-19 convalescent patients and subjects vaccinated with a full course of Gam-Covid-Vac. The "hybrid" immunity showed not only a significantly higher (compared with groups No. 1 and No. 2) level of IgG antibodies (median 228 BAU/ml vs 75 or 119 BAU/ml, p < 0.001), but also a higher level of avidity (IA 90.5% vs 54.5 and 76.6, respectively, p < 0.001, 4M urea). In the test for assessing the avidity index with the denaturing agent 8M urea in patients with "hybrid immunity", the median level of IA was 25% versus 14.8% and 16% in COVID-19 convalescents and vaccinated subjects (p < 0.001), only in 8 patients IA was higher than 50%. While comparing a single infection of COVID-19 with a full course of Gam-Covid-Vac, it was shown that vaccination leads to higher IgG levels (median values in groups 119 and 75 BAU/ml, p < 0.001) and to a higher avidity index (median 76.6% vs 54.5%). Thus, the more rapid induction of high-avidity antibodies was in vaccinated individuals at early stages of immunization (up to 4 months), during the period when IgG avidity maturation has not yet been completed. Our results showed that during this period vaccination leads to production of antibodies with avidity index at median level of 82% versus 36% in COVID-19 convalescents at similar time point.Copyright © 2023 Saint Petersburg Pasteur Institute.

ABSTRACT
Background ACE is a potent pro-inflammatory modulator that controls chemokines and adhesion molecules, and elevated ACE activity associated with immunoinflammatory conditions, including cardiovascular diseases (CVD) and diabetes. The ACE inhibitors are recommended as primary treatment for these illnesses. ACE is a peptidyl-dipeptidase that catalyses Angiotensin I to Angiotensin II, whilst inactivating bradykinin during blood pressure regulation via the Renin-Angiotensin System. The purpose of this study is to establish a reference interval (RI) for ACE in the Irish population after COVID, and to examine if there is an underlying correlation between ACE concentrations and a range of biomarkers. Methods Serum samples of 200 randomly selected patients were obtained from several Irish hospitals in March 2022 (in compliance withGuidance on Anonymisation and Pseudonymisation, June 2019). We analysed for ACE (Buhlmann reagents), HBA1C, 25OHD and other biomarkers on the Abbott Architect ci8200. Full Blood Count was measured on Sysmex CS-2500. The statistical analysis used the EP Evaluator 11.3.0.23 and SPSS 22.0 software. Results The RI based on the central 95% of data was 8-78 U/L. This is higher than the RI proposed by the manufacturer (20-70 U/L) but is very close to our RI (5-79 U/L) from 2019. We found a significant positive correlation between ACE concentration and HBA1c, Urea, Creatinine, White Blood Cells (p<0.0001), Glucose (p=0.02), LDL (p=0.03), Neutrophils (p=0.003), Lymphocytes (p=0.001). A significant negative correlation was observed with 25OHD (p<0.0001). Conclusions This study did not show any notable change in the RI for ACE after COVID in Ireland. The significant positive correlations with HBA1c and other biomarkers may indicate the importance for ACE testing for diabetic management and progression, but further studies will be needed. Patients' overall health and medical history should always be considered when evaluating ACE results, including Vitamin D levels.
ABSTRACT
Background: Coronavirus disease 2019 (COVID-19) may result in a severe acute respiratory syndrome that leads to a worldwide pandemic. Despite the increasing understanding of COVID-19 disease, the mortality rate of hospitalized COVID-19 patients remains high. Objective(s): To investigate the risk factors related to the mortality of admitted COVID-19 patients during the peak of the epidemic from August 2021 to October 2021 in Vietnam. Method(s): This is a prospective cohort study performed at the Hospital for Rehabilitation-Professional diseases. The baseline and demographic data, medical history, clinical examination, the laboratory results were recorded for patients admitted to the hospital with confirmed COVID-19. A radiologist and a pulmonologist will read the chest radiographs on admission and calculate the Brixia scores to classify the severity of lung abnormalities. Patients were followed up until beingrecovered or their death. Comparison of clinical and subclinical characteristics between recovery and death groups to find out risk factors related to the death of COVID-19 patients Results: Among 104 admitted COVID-19 patients, men accounted for 42.3%, average age of 61.7 +/- 13.7. The most common symptoms were fever 76.9%, breathlessness 74%, and fatigue 53.8%. The majority (84.6%) of the study population had at least one co-morbidity, including hypertension (53.8%), diabetes (25.9%), gastritis (19.2%), ischemic heart disease (15.4) %), stroke (9.6%) and osteoarthritis (9.6%). The rate of mild and moderate COVID-19 is 13.4%, severe 32.7%, and critical 40.4%. There are 88 inpatients (84.6%) who needed respiratory support. The median hospital stay was 13 days (IQR 10-17.75 days). The rate of intubated patients with mechanical ventilation was 31.7%. The overall mortality rate was 29.8%. Risk factors related to death included Brixia scores > 9, Urea > 7 mmol/L, Ferrtin > 578 ng/ml, Failure to get vaccinated, Age > 60 years, and Low Oxygen SpO2 < 87% (BUFFALO). Conclusion(s): The main result of the study is the independent risk factors related to the death of admitted COVID-19 patients including Brixia scores > 9, Urea > 7 mmol/L, Ferrtin > 578 ng/ml, Failure to get vaccinated, Age > 60 years, and Low Oxygen SpO2 < 87% ((BUFFALO) which suggests that these COVID-19 patients should be closely followed up.Copyright © 2023 Hanha et al.
ABSTRACT
Background: In ongoing SARS CoV-2 pandemic, understanding antibody responses have played a key role in measuring extent of exposure, protection from reinfection, vaccine efficacy and serodiagnosis. Antibody avidity is total binding strength of immunoglobulin G (IgG) toward its target epitope. High antibody avidity has been correlated with effective neutralization of the SARSCoV-2 virus. However, the data on avidity responses against COVID-19 infection and vaccination are limited. Objective(s): To understand the avidity responses among sera of naturally infected, recovered COVID-19 patients;naive Covaxin, Covishield vaccinees and breakthrough infections. Material(s) and Method(s): In this study, we utilized an in-house developed SARS-CoV-2 anti-spike receptor binding domain (SRBD) IgG ELISA to optimize the avidity assay. A panel of anti-SARS-CoV- 2 SRBD IgG positive serum samples were treated with known concentration of a chaotropic agent (urea) for disruption of the noncovalent interactions of the antigen-antibody complex. This disruption causes low avidity antibodies to dissociate which gives the percentage of high avidity antibodies present in a serum sample. Additionally, the optimized assay was used to understand the avidity responses among sera belonging to individuals naturally infected and recovered after COVID-19, naive Covaxin and Covishield vaccinees;followed by breakthrough infections. Result(s) and Conclusion(s): The anti-SRBD avidity progressively elevated over a period of twelve months. Moreover, overall antibody avidity responses were similar in the case of natural infection and naive two doses of Covaxin and Covishield vaccinated individuals. However, avidity responses were high among individuals with a breakthrough infection as compared to naive vaccinees.
ABSTRACT
CONTEXT: Vancomycin (VCM), an important antibiotic against refractory infections, has been used to treat secondary infections in severe COVID-19 patients. Regrettably, VCM treatment has been associated with nephrotoxicity. Vitamin D3 can prevent nephrotoxicity through its antioxidant effect. OBJECTIVE: This study tests the antioxidant effect of vitamin D3 in the prevention of VCM-induced nephrotoxicity. MATERIALS AND METHODS: Wistar Albino rats (21) were randomly divided into 3 groups: (A) control; (B) VCM 300 mg/kg daily for 1 week; and (C) VCM plus vitamin D3 500 IU/kg daily for 2 weeks. All the rats were sacrificed and serum was separated to determine kidney function parameters. Their kidneys were also dissected for histological examination and for oxidative stress markers. RESULTS: Lipid peroxidation, creatinine, and urea levels decreased significantly (p < 0.0001) in the vitamin D3-treated group (14.46, 84.11, 36.17%, respectively) compared to the VCM group that was given VCM (MIC<2 µg/mL) only. A significant increase was observed in superoxide dismutase levels in the vitamin D3-treated group (p < 0.05) compared to rats without treatment. Furthermore, kidney histopathology of the rats treated with vitamin D3 showed that dilatation, vacuolization and necrosis tubules decreased significantly (p < 0.05) compared with those in the VCM group. Glomerular injury, hyaline dystrophy, and inflammation improved significantly in the vitamin D3 group (p < 0.001, p < 0.05, p < 0.05, respectively) compared with the VCM group. DISCUSSION AND CONCLUSIONS: Vitamin D3 can prevent VCM nephrotoxicity. Therefore, the appropriate dose of this vitamin must be determined, especially for those infected with COVID-19 and receiving VCM, to manage their secondary infections.

Background & Objective: Covid-19 infection has diverse effect on human health. We aimed to evaluate the effect of COVID-19 pandemic on the young stroke cases in an emergency services in a tertiary hospital in Istanbul, Turkey. Method: A total of 86 patients younger than 50 years confirmed to have stroke seen between January 1, 2019 and December 31, 2020 were included in the study. The year 2019 was defined as the pre-pandemic period and the year 2020 as the pandemic period. The patients' stroke type, localization, mortality, laboratory and imaging data were evaluated. Results: Eighty-six patients were included in the study. The mean age was 38.69±5.39 years, 49 (57%) were female. Of the patients, 78 (90.7%) were ischemic and 8 (9.3%) were hemorrhagic stroke. In the pandemic group, ischemic stroke was observed in 55 (96.5%) and hemorrhagic stroke in 2 (3.5%) (p=0.010). While the mean age of the patients in the survival group was 39.24±5.70 years, it was 36.61±3.38 years in the mortality group (p=0.008). While the mortality was 18 (20.9%) overall, it was 16 (18.6%) patients during the pandemic period, and 2 (2.3%) patients in the pre-pandemic period, the difference was statistically significant. (p=0.014). Conclusion: COVID-19 infection appear to increase the risk of ischemic stroke and worsens the mortality among the young. More comprehensive and prospective studies are needed to confirm this observation. © 2023, ASEAN Neurological Association. All rights reserved.
ABSTRACT
Spontaneous pneumomediastinum (SPM) is a decisive complication reported to be associated with COVID-19. Here, we present a case of SPM in a COVID-19positive patient that was not caused by any iatrogenic or known reasons. At the time of admission, the patient was COVID-positive and distressed. He was immediately subjected to hematological and radiological investigations (chest X-ray, HRCT), which confirmed pneumomediastinum. The patient was hypoxic and hypotensive even after receiving ionotropic support. Considering the patient's critical condition, a mediastinal pigtail catheterization was performed instead of a thoracotomy, and the catheter was in situ for nine days. Arterial blood gas was monitored during the hospital stay, and supplementary oxygen therapy was provided accordingly. The patient subsequently recovered and was discharged. Hence, SPM in this COVID patient was treated by pigtail catheterization, and major surgical interventions were avoided.Copyright © 2023 LookUs Scientific. All rights reserved.
ABSTRACT
Background and aim: The correlation between Covid-19 and nonrespiratory bacteria is mostly unexplored. The following considerations led us to investigate a possible correlation between Hp and SARS-CoV2: both are microbial agents with a very large-scale epidemiology;both can cause GI symptoms;both can persist in the GI tract for long time [Fei Xiao, 2022];patients with pre-existing HP gastric colonization, once infected by SARS-CoV-2, complain more frequently and with greater severity of GI symptoms such as abdominal pain and diarrhea [Balamtekin, 2019];SARS-CoV-2 binds ACE-2 receptors to enter cells, which are widely expressed in the GI tract. In addition, Hp is known to increase the expression of ACE-2 receptors. This study aims to investigate, by C13 Urea BT, the prevalence of Hp infection and the DOB (delta over baseline), in pre-pandemic period (pPP), from Sept. 2017 to Dec. 2019, and during Covid-19 pandemic period (PP), from Jan. 2020 to Apr. 2022, to evaluate whether SARS-CoV-2 and Hp infection association is only due to chance or whether represents a pathogenetic correlation. Material(s) and Method(s): This is a retrospective preliminary study on 1532 randomized patients: 825 and 707 referring respectively to pPP and PP. Result(s): 316 patients underwent C13 Urea BT for the diagnosis of Hp infection: 36 out of 179 (20.11%), and 74 out of 137 (54.01%), respectively in pPP and in PP, tested positive for Hp. The DOB of patients tested during the PP was 40.4+/-17.5, significantly higher when compared to the mean value found in pPP: 17.4+/-16.5 (p=0.0001). [Figure presented] Conclusion(s): Neglecting the search for Hp, also due to difficulties encountered in this period to access BT, represents a risk condition for gastric diseases, especially considering the remarkable elevation of the prevalence and the DOB caused, somehow, by the SARS-CoV-2 virus. Particularly, the higher the DOB, the higher the bacterial load, but, more significantly, the greater the ability of the bacterial strains to produce urease: the strains with the greatest urease-activity are cagA+ strains (those capable of producing the oncogenic protein involved in the process of carcinogenesis) [Moreno-Ochoa, 2020]. Thus, it can be assumed that the higher the DOB, the greater the risk of developing serious gastric problems in the absence of treatment. So, in conclusion, Sars-Cov-2 and HP infection may influence each other. GI morphological and functional alterations due to Sars-Cov-2 infection, which can promote HP colonization and replication, need further investigation.Copyright © 2023.

ABSTRACT
Background: Today, various drugs have been investigated as the primary or complementary treatment for coronavirus disease 2019 (COVID-19). N-acetylcysteine (NAC) has been used as a mucolytic in pulmonary diseases. This drug apparently contributes to the retrieval of the intracellular antioxidant system. Objective(s): This study aimed to determine the efficacy of NAC in severe COVID-19 patients admitted to the intensive care unit (ICU). Method(s): This single-blinded randomized controlled phase III clinical trial included 40 patients with confirmed COVID-19 (based on polymerase chain reaction) admitted to the Shahid Mohammadi Hospital's ICU, Bandar Abbas, Iran, in 2020. All cases had severe COVID-19. They were allocated randomly to two equal groups. Patients in the control group received standard drug therapy based on the treatment protocol of the national COVID-19 committee, while those in the NAC group received a single dose of intravenous NAC (300 mg/kg) upon admission to the ICU in addition to standard drug treatment. Clinical status and laboratory tests were done on admission to the ICU and then 14 days later or at discharge without knowing the patient grouping. Result(s): The two groups were comparable regarding age, gender, and other baseline laboratory and clinical parameters. At the final evaluation, respiratory rate (21.25 +/- 4.67 vs. 27.37 +/- 6.99 /min) and D-dimer (186.37 +/- 410.23 vs. 1339.04 +/- 2183.87 ng/mL) were significantly lower in the NAC group (P = 0.004 and P = 0.030, respectively). Also, a lower percentage of patients in the NAC group had lactate dehydrogenase (LDH) <= 245 U/L (0% vs. 25%, P = 0.047). Although the length of ward and ICU stay was shorter in the NAC group than in controls, the difference was statistically insignificant (P = 0.598 and P = 0.629, respectively). Mortality, on the other hand, was 75% in the control group and 50% in the NAC group, with no statistically significant difference (P = 0.102). Concerning the change in the study parameters, only the decrease in diastolic blood pressure (DBP) was significantly higher with NAC (P = 0.042). The intubation and mechanical ventilation rates were higher, while oxygen with mask and nasal oxygen rates were lower with NAC, but the difference was statistically insignificant. Conclusion(s): Based on the current research, NAC is related to a significant decrease in RR, D-dimer, and DBP in severe COVID-19. Also, LDH was significantly lower in the NAC group than in the controls. More research with larger sample sizes is needed to validate the current study results.Copyright © 2023, Author(s).
ABSTRACT
BACKGROUND: One of the most precocious Italian COVID-19 outbreaks began in February 2020 in Medicina, a small town in the province of Bologna. We compared the characteristics of different cohorts, to identify potential predictive factors for outcome: patients of Medicina outbreak versus those of the surrounding district (Imola), and before or after the local medical intervention. METHOD(S): Between March the 3rd and April the 9th, 2020 167 adults with COVID-19 were admitted to the Emergency Department (ED) (78 from Medicina cluster, 89 from Imola district). Data at ED presentation were collected;hospitalized patients were followed until death or discharge. RESULT(S): Medicina and Imola cohorts were similar in age, main comorbidities, clinical presentation, laboratory tests, arterial blood gas analysis (ABG), death and acute respiratory distress syndrome (ARDS) rates. Age, hypertension, diabetes, chronic obstructive pulmonary disease, dyspnea, body temperature, quickSOFA Score, elevated C-reactive protein (CRP), creatinine, urea, DELTA A-a O2, respiratory rate and FiO2 were associated with death and ARDS. Elevated Glasgow Coma Scale, diastolic blood pressure, oxygen peripheral saturation, P/F and pH were associated with patient survival and protective from ARDS. After the intervention in Medicina district, patients presenting at ED were younger and with long-lasting symptoms;CRP values were significantly lower, ABG and respiratory clinical parameters were less severely impaired. These differences did not affect the outcome. CONCLUSION(S): Since the results of our study are consistent with worldwide evidences, we suggest that the early insight of a small local SARS-CoV-2 outbreak can be representative and predictive of the subsequent course of the virus in wider areas. This must be kept in mind to manage next epidemic waves.Copyright © 2022 EDIZIONI MINERVA MEDICA.
ABSTRACT
COVID-19 is highly transmissible in humans with mild flu-like symptoms, but some patients, especially the elderly and people with underlying diseases, evolve critical condition and rapidly develop acute respiratory distress syndrome, respiratory failure, multiple organ disorder and death. The rapid viral replication of SARS-COV-2 gives rise to inflammatory response, cellular destruction and induces the release of cytokines and chemokines then activate immune responses, leading to cytokine storms and aggravations. The RT-PCR test remains gold standard as it detect virus nucleic acid but it is time consuming and has a high prevalence of false negative results. Several inflammatory markers have some tracing and detecting accuracy for disease severity and fatality. Para-clinical investigations including laboratory tests and radiologic findings play an important role in early diagnosis and treatment monitoring of severe acute respiratory syndrome and COVID-19. This study aims to explore the evaluation of inflammatory and non-inflammatory parameters in the disease pathogenesis of COVID-19 and assess how their levels vary depending on the severity of the disease. By doing so, it gives clinicians a tool to group patients and predict prognosis and mortality. The inflammatory parameters included Ferritin, Lactate dehydrogenase (LDH), D- dimer, Interleukin 6 (IL6) and non-inflammatory parameters includes Glucose, Urea, Creatinine, SGOT, SGPT in Covid-19 infected patients. Total subjects were divided in three groups that is control, Group 1 is covid-19 positive patients without comorbidities and Group 2 is covid-19 positive patients with comorbidities. As compared to control Ferritin, LDH, IL6, D-Dimer significantly increased in Group 1 & Group 2, and further as compared with Group 1, these inflammatory parameters significantly elevated in Group 2. As compared to control, Blood Glucose, Urea, Creatinine, SGOT, and SGPT statistical not different in Group 1 but when compared with Group -2 these parameters significantly increased. Further as compared to Group 1 Blood Glucose, Urea, Creatinine, SGOT, and SGPT significantly increased in Group 2. As compared to control Total protein and Albumin statistically not different in Group 1 & Group 2, and there was no any statistical difference in the levels of Total protein and albumin in Group 1 and Group 2. This change of levels of parameters is used as an adjunct in clinical practice to guide treatment and admission to Intensive care unit and also it may improve prognosis and decrease the mortality rates.

ABSTRACT
Introduction: COVID-19 infection has a myriad of presentation. Rural India and other developing nations are relatively resource poor, not having access to modern specialized investigations. In this study, we tried to evaluate only biochemical parameters in predicting the severity of the infection. The aim of this study was to find a cost-effective means to predict the clinical course at the time of admission and thereby to reduce mortality and, if possible, morbidity by timely intervention. Materials and Methods: All COVID-19-positive cases admitted at our hospital from March 21 to December 31, 2020, were recruited in this study. The same acted as sham control at recovery. Results: We observed a significant difference in biochemical parameters at the time of admission and discharge, between mild/moderate disease and severe disease. We found slightly deranged liver function tests at admission, which becomes normal at the time of discharge. Urea, C-reactive protein (CRP), procalcitonin, lactate dehydrogenase, and ferritin concentrations in severe/critical patients were significantly higher than that in the mild/moderate group. Receiver operating characteristic curves were plotted to predict the severity on the basis of biochemical parameters independently, of the patients based on these values. Conclusion: We proposed cutoff values of certain biochemical parameters, which will help in judging the severity of the infection at admission. We developed a predictive model with a significant predictive capability for CRP and ferritin values, using normal available biochemical parameters, routinely done in resource-poor centers. Clinicians working in resource-poor situations will be benefitted by having an idea of the severity of the disease. Timely intervention will reduce mortality and severe morbidity.
Résumé Introduction: L'infection au COVID19 a une myriade de présentations. L'Inde rurale et d'autres pays en développement sont relativement pauvres en ressources, non avoir accès aux enquêtes spécialisées modernes. Dans cette étude, nous avons essayé d'évaluer uniquement les paramètres biochimiques pour prédire la gravité de l'infection. Le but de cette étude était de trouver un moyen rentable de prédire l'évolution clinique au moment de l'admission et ainsi de réduire la mortalité et, si possible, la morbidité par une intervention rapide. Matériels et méthodes: Tous les cas positifs au COVID19 admis à notre hospitalisés du 21 mars au 31 décembre 2020, ont été recrutés dans cette étude. La même chose a agi comme un contrôle factice lors de la récupération. Résultats: Nous avons observé une différence significative dans les paramètres biochimiques au moment de l'admission et de la sortie, entre une maladie légère/modérée et une maladie grave. Nous avons trouvé des tests de la fonction hépatique légèrement dérangés à l'admission, qui deviennent normaux au moment de la sortie. Urée, protéine Créactive (CRP, les concentrations de procalcitonine, de lactate déshydrogénase et de ferritine chez les patients sévères/critiques étaient significativement plus élevées que chez les patients légers/modérés groupe. Les courbes caractéristiques de fonctionnement du récepteur ont été tracées pour prédire la gravité sur la base de paramètres biochimiques indépendamment, deles patients en fonction de ces valeurs. Conclusion: Nous avons proposé des valeurs seuils de certains paramètres biochimiques, qui permettront de juger de la gravité de l'infection à l'admission. Nous avons développé un modèle prédictif avec une capacité prédictive significative pour les valeurs de CRP et de ferritine, en utilisant les paramètres biochimiques normaux disponibles, systématiquement effectués dans les centres pauvres en ressources. Les cliniciens travaillant dans des situations où les ressources sont limitées bénéficier d'avoir une idée de la gravité de la maladie. Une intervention rapide réduira la mortalité et la morbidité grave. Mots-clés: COVID19, ferritine, lactate déshydrogénase, urée.
