To determine the impact of NAT2 gene variants on the risk of developing and the progression of severe COVID-19-associated pneumonia in patients from the Poltava region of Ukraine. The study included 117 patients who were diagnosed with severe COVID-19 pneumonia and received treatment in the intensive care unit. The NAT2 gene variants were identified through the PCR-RFLP method. The presence of the AA genotype of the A803G variant in patients with severe COVID-19 pneumonia is associated with an almost 3-fold reduction in the risk of lethal outcomes. The presence of the TT genotype of the C481T variant was associated with the need for artificial lung ventilation. Patients in the study group with a heterozygous GA genotype of the G590A variant demonstrated a notable rise in the risk of developing systemic inflammatory response syndrome and acute respiratory distress syndrome, with a nearly 2.5-fold and 3-fold increase, respectively. The G857A variant was not associated with the risk of developing the above-- mentioned complications in the examined patients.

The questionnaire covered six sectors: demographics, medical history, COVID-19 infection and vaccination status, obstetric and gynecological history, menstrual cycle history, and specific questions about cycle length, flow, and any symptoms before and after each vaccine shot. Participants included Jordanian females who had received any type of COVID-19 vaccine. Among the participants analyzed, two-thirds were between the ages of 20-35, and the majority had a normal BMI (59.6%). Most participants were single, nulliparous, and had never used contraception methods (79.3%, 82.0%, and 93.8%, respectively). Only a small percentage had other risk factors influencing menstrual cycle changes, such as surgical procedures (10.5%) and specific medications (8.10%). Baseline menstrual information was recorded. Forty percent of participants experienced changes in menstrual duration, and approximately one-fifth reported heavier and more severe premenstrual syndrome (PMS) symptoms. Body mass index (BMI) was directly correlated with bleeding intensity after vaccination. Parity was weakly directly proportional to bleeding intensity after vaccination. However, BMI and parity did not significantly correlate with menstrual duration, menstrual cycle length, PMS symptoms, or cramps after vaccination. In a population of young, non-sexually active women with a normal BMI, most participants did not experience significant changes in their menstrual cycles after receiving the COVID-19 vaccine. Only one-fifth of participants reported shorter duration, heavier bleeding, more frequent, more painful, and more severe PMS symptoms post-vaccination.","PeriodicalId":44030,"journal":{"name":"Current Respiratory Medicine Reviews","volume":"7 4","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139266972","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: This cross-sectional study was conducted on 86 patients with COVID-19. A 5 ml venous blood sample was taken on the first day of hospitalization. VEGF was measured with the ELISA method using the Hangzhou East biopharm VEGF ELIZA Kit. Results: The mean age of patients was 56 ± 15 years. The mean plasma level of VEGF was 2877.07 ± 104.77 ng/ml. There was no significant relationship between VEGF levels and COVID-19 severity (P = 0.55). The percentage of pulmonary infiltration &gt; 50 in the severe group (72.7%) was higher than that of the non-severe group (2.4%) (P = 0.001). There was a significant relationship between COVID-19 severity and the levels of LDH, neutrophil/lymph ratio, and CRP. Regarding medications, remdesivir was used more in the severe group (70.5%) than in the non-severe group (45.2%) (P = 0.018). Conclusion: Although plasma VEGF levels were higher in the severe group than in the non-severe group, no significant relationship was found between the plasma level of VEGF and COVID-19 severity, which might be due to the small sample size. VEGF may be a valuable scientific marker, but in this study, it was not as useful as other markers in identifying COVID-19 severity. In addition, there was a direct and significant relationship between COVID-19 severity and the inflammatory markers LDH, neutrophil/lymph, and CRP. Therefore, measurement of inflammatory markers can assist in the early identification and prediction of severity and disease progression in COVID-19.","PeriodicalId":44030,"journal":{"name":"Current Respiratory Medicine Reviews","volume":"122 8","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136351881","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Objective:: To compare the thoracic CT findings, GGO volumes, and GGOs’ lung uptake rates among patients with COVID-19 variants. Methods:: Thoracic CT images of 83 patients with non-variant, 78 patients with alpha variant, 93 patients with delta variant, and 73 patients with omicron variant having positive Real-Time Polymerase Chain Reaction test results were analyzed retrospectively. GGO volumes and lung volumes were calculated by using the Cavalieri Principle. Differences in CT findings, ground-glass opacity volumes, and lung involvement rates between non-variant and variant groups were evaluated. Results:: There were significant differences found in the incidence of GGOs (p < 0.001), air bronchogram (p = 0.007), reticulation (p = 0.002) and subpleural lines, and linear opacities (p = 0.034) between non-variant and variant groups. GGO uptake rates (ground glass opacity volumes × 100 ÷ lung volume) were 8.88% in the non-variant, 4.83% in the alpha variant, 3.50% in the delta variant, and 2.02% in the omicron variant. In estimating variant groups, it was determined that the increase in the rate of GGOs in the right lung increased the probability of having an omicron variant, whereas the presence of nodules decreased it. The possibility of the delta variant increased with an increase in the rate of ground glass opacities in the left lung. Conclusion:: Thoracic CT findings solely can be helpful in distinguishing COVID-19 variants. Decreased frequency of uptake rates of GGOs suggested that the severity of COVID-19 disease was gradually decreasing.","PeriodicalId":44030,"journal":{"name":"Current Respiratory Medicine Reviews","volume":"73 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135684930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The absence of trustworthy preclinical models that replicate the anatomical, immunological, and bioelectrical characteristics of human CF lungs restricts the discovery of new therapies for the disease. Alternative carriers to liposomes, polymeric nanoparticles, and inorganic carriers include lipid-based nanocarriers (LBCs). Delivering medicines, nucleic acids, proteins, peptides, nutraceuticals, and cosmetics via LBCs has received more and more attention in recent years. Due to their simple production, physicochemical stability, and scalability, these nanocarriers have caught the attention of the industrial sector. Because of these qualities, LBCs are well suited for industrial manufacturing. Clinical trials are already being conducted on a number of LBC-containing items and are likely to swiftly grow in popularity. For commercial applications to produce enough formulations for clinical research, a large-scale manufacturing facility is necessary. The mainstay of treatment for CF, asthma, and chronic obstructive lung disease is the inhalation of corticosteroids and topical bronchodilators. These drugs are given through a metered-dose inhaler (MDI), a dry powder inhaler (DPI), a jet, or an ultrasonic nebulizer.
