Prospects for the Protective Mechanisms and Compounds of Bufei Huoxue Capsule against COVID-19 Convalescence: Evaluation of Integrating UHPLC-HRMS Analysis and Network Pharmacology Strategy.
INTRODUCTION
Most COVID-19 survivors are troubled with chronic persistent symptoms, which have currently no definitive treatments. Bufei Huoxue (BFHX) capsule exerts clinical benefit, while the material basis and molecular mechanism remain unclear.
AIM
The study aimed to elucidate the protective mechanisms of BFHX capsules against COVID-19 convalescence. UHPLC-HRMS and various databases were employed to explore potential compounds and targets. PPI, MCODE, transcription factor (TF), and miRNA analyses were conducted to receive hub targets and corresponding upstream regulators.
METHOD
Molecular docking was applied to verify the binding activity of compound and target. Further, GO, KEGG, WIKI, and Reactome analyses were performed, and compound-targetsymptom and gene-disease networks were constructed. A total of 127 compounds and 313 targets were acquired. A sum of 10 hub targets were screened and showed good binding affinities with critical compounds.
RESULT
MLLT1, CBFB, and EZH2 were identified as key TFs, and hsa-mir-146a-5p, hsa-mir- 26b-5p, and hsa-mir-24-3p were predicted to be important miRNAs. BFHX capsule may alleviate the symptoms by targeting TNF, IL-6, IFNG, and TGF-β1. Besides, BFHX capsule may exert a therapeutic effect on respiratory disease (especially pulmonary fibrosis and lung infection) and multi-system damage during COVID-19 convalescence by regulating cytokine-cytokine receptor interaction, as well as TGF-β, TNF, and Toll-like receptor signaling pathways.
CONCLUSION
In summary, BFHX capsule may exert a therapeutic effect on multi-system damages during COVID-19 convalescence through multiple compounds (such as albiflorin, isopsoralen, and neobavaisoflavone), multiple targets (such as TNF, IL-6, and EGF) and multiple pathways (TGF-β, TNF, and Toll-like receptor signaling pathways).

BACKGROUND
The development of a cytokine storm in Coronavirus Disease 2019 (COVID-19) infection can make the disease fatal. We hypothesize that this excessive cytokine production impairs mucosal healing. IL-17 and IL-22 are cytokines that play a key role in protecting and regenerating mucosal tissues.IL-17 and IL-22 support each other and the imbalance between them plays a role in the pathogenesis of many rheumatologic diseases.
OBJECTIVE
To investigate whether COVID-19 severity is related to IL17, IL-22, and the IL-17/IL-22 ratio.
METHODS
The study was planned prospectively and included 69 patients with active COVID-19 infection.Three groups were created: patients with upper respiratory tract infection, pneumonia, and cytokine storm. Blood samples were taken from the patients upon their first admission and serum levels of IL-17 and IL-22 were measured using the enzyme-linked immunosorbent assay (ELISA). We assessed the relationship between IL17, IL22, IL17/IL22 ratio, clinical and lung involvement by comparing them with the healthy group.
RESULTS
The levels of IL-17 were significantly higher in COVID-19 patients with upper respiratory tract infection compared to the control group (p=0.027). IL17/IL-22 ratio significantly increased in patients with cytokine storm compared to the healthy controls (p=0.027). Serum levels of IL-22 were negatively correlated with the CO-RADS score (r=-0.31, p=0.004), while IL-17/IL-22 ratio was positively correlated with the CO-RADS score (r= 0.29, p=0.008).
CONCLUSION
Levels of IL-17, IL-22 and IL-17/IL-22 may provide valuable insights into the progression of COVID-19.

OBJECTIVES
This research with gastrointestinal cancer patients analyzed the expected outcomes of nursing interventions on a) patient adherence to treatment; b) patient satisfaction with nursing care; and c) health of body conditions such as lung function.
METHODS
All patients (60 individuals) who underwent chemotherapy at The First Affiliated Hospital of Soochow University, Department of Traditional Chinese Medicine, were divided into two equal groups. Group 1 received planned care and Group 2 received evidence-based nursing interventions.
RESULTS
The results showed that treatment adherence was higher in Group 2 than in the control group (p = 0.01). In addition, there was a higher rating by patients for the quality of nursing care (p = 0.01), as well as a higher score obtained for lung function (p = 0.01). Treatment adherence resulted in a decrease in the secondary infection rate in Group 2 (p = 0.05).
CONCLUSION
The results showed that quality nursing intervention is effective for lung function improvement, stress level reduction, treatment plans, and a reduction of secondary infections.

Prognostic Nutritional Index as a Prognostic Indicator for the Occurrence of Postoperative Complications in Patients with Esophageal Squamous Cell Carcinoma Following Neoadjuvant Immunochemotherapy.
BACKGROUND & AIMS
The objective of this study was to evaluate the prognostic nutritional index (PNI) as a predictor of short-term postoperative complications in esophageal squamous cell carcinoma patients undergoing neoadjuvant immunochemotherapy.
METHODS
Clinical data were collected from 77 patients undergoing radical esophageal cancer surgery after neoadjuvant immunochemotherapy at Tongji Hospital from January 2022 to January 2023. The receiver operating characteristic curve (ROC) was utilized to establish the optimal cut-off point for the PNI. Subsequently, patients were stratified into low and high PNI groups according to this cut-off point, and comparisons were made between the two groups in terms of clinical data and postoperative complications.
RESULTS
Out of the 77 patients included in the study, 31 were categorized in the low PNI group and 46 in the high PNI group, with a defined cutoff point of 47.38. Significant statistical variances were noted in the occurrence rates of general complications (P < 0.001), pulmonary infections (P < 0.001), and anastomotic fistula (P = 0.034) between the two groups. The low PNI group displayed elevated rates of these complications in comparison to the high PNI group.
CONCLUSION
The research findings indicate that preoperative nutritional assessment using the PNI can effectively predict short-term postoperative complications in esophageal squamous cell carcinoma patients who have undergone neoadjuvant therapy. Furthermore, the results suggest that implementing nutritional interventions for patients with moderate-to-severe malnutrition, as indicated by preoperative PNI evaluation, may help reduce the incidence of postoperative complications.

Drug-resistant tuberculosis is a burgeoning threat to public health requiring novel strategies to combat the infection. Although national tuberculosis elimination programs focus on improving health services, challenges in eradicating tuberculosis still exist. Factors attributing to unfavorable outcomes are unknown in Warangal district of Telangana state. This study included 296 patients diagnosed with multidrug-resistant pulmonary tuberculosis. The study participants followed up for a maximum of 20 months to determine treatment outcomes. Statistical applications of Kaplan-Meier curve and log-rank test used to find the survival probabilities in subgroups. The survival of multidrug-resistant pulmonary tuberculosis patients was ascertained, in male and female patients, aged between 31 and 50 years. Resistance to rifampicin was prominent. The study found a survival rate of 76.68% and a mortality rate of 23.31%. The log-rank test revealed a significant difference in survival in subcategories with and without comorbidities ( = .03), non-adherence to treatment ( = .0001), treatment duration ( = .02), regimens ( = .01), and grading of radiograph ( = .0001). This study identified factors that influenced the survival probability of multidrug-resistant pulmonary tuberculosis patients, including comorbidities, weight band, non-adherence to treatment, treatment duration, regimens, and grading of radiograph. These findings emphasize the need for enhanced management strategies to improve treatment outcomes.

Antimicrobial resistance pattern in aerobic bacteria isolated from endotracheal aspirate in ventilator-associated pneumonia: Ten years observation from a tertiary care hospital.
BACKGROUND AND AIMS
Ventilator-associated pneumonia (VAP) is a nosocomial infection associated with high morbidity and mortality. This study was undertaken to monitor the trend of the demographical details, comorbid conditions, bacterial etiological agents, and their antibiogram causing VAP in adults in the year 2008, 2013 and 2018.
MATERIAL AND METHODS
A retrospective study conducted at the Department of Microbiology, Hospital Infection control and Quality Control at a tertiary care teaching hospital. All the adult patients with more than 48 h of the mechanical ventilator with endotracheal intubation with Clinical Pulmonary infection Score >6 with suspicion of VAP were included in the study at a difference of 5 years, i.e., 2008, 2013, and 2018.
RESULTS
A total of 338 patients were included in the study, of which males accounted for more than two-third of the patients studied. Nearly 45% of the patients belonged to geriatric (>60 years) age group. The most common comorbid conditions were chronic obstructive pulmonary disease, hypertension and diabetes mellitus. Among the gram-negative isolates, , species, and were the most common. There is an emergence of resistance to most commonly administered antimicrobial agents like aminoglycosides, levofloxacin, piperacillin/tazobactum, and carbapenems during the study period.
CONCLUSION
This is a ten-year study on the antibiotic resistance pattern of organisms causing VAP. As far as the authors are aware, this is the first study addressing the pattern of change in drug resistance in the organisms causing VAP over a decade. The emergence of multi-drug resistant (MDR) MDR pathogens, especially in intensive care unit (ICU), is a great concern for the intensivist and infection control physicians. Preventive measures need to be undertaken to control the spread of these pathogens to the patients in the ICU.

Diagnosing pneumonia (PJP) can be complex, particularly in cases of significant respiratory failure. The 1,3-β-D-glucan (BDG) serum assay has emerged as a promising non-invasive diagnostic tool for detecting fungal infections, including PJP. However, factors that can confound the interpretation of BDG levels by causing elevation in serum levels have been documented. Here, we present the case of 51-year-old woman with underlying autoimmune disorder, hematologic malignancy, and chronic steroid use, who was admitted for acute hypoxemic respiratory failure. Obtaining the BDG assay after the administration of intravenous immunoglobulin (IVIG) posed a diagnostic challenge, as the patient was unable to undergo bronchoscopy. This circumstance led to a debate regarding the possibility of a false-positive BDG due to IVIG use or the presence of PJP. Ultimately, the patient was empirically treated for PJP. This case underscores the importance of comprehending factors that may contaminate BDG results, particularly in immunocompromised individuals.

The Factors for the Occurrence of Pulmonary Infection after Gastrointestinal Surgery and the Construction of a Predictive Model Using sTREM-1 and TIM-4: A Retrospective Study.
AIM
Identifying and intervening with high-risk postoperative pulmonary infections patients pose challenges in clinical practice. This study aims to conduct a comprehensively analysis of the risk factors and predictive factors associated with post-gastrointestinal surgery pulmonary infections and to develop a predictive model that can predict occurrence of pulmonary infection.
METHODS
A retrospective analysis was conducted on 96 patients who underwent gastrointestinal surgery at our hospital from May 2021 to October 2023. The occurrence rate of postoperative pulmonary infections was calculated, and patients were categorized into two groups: those with pulmonary infections (the occurrence group) and those without pulmonary infections (the non-occurrence group). Logistic regression analysis was utilized to identify the risk factors for post-gastrointestinal surgery pulmonary infections and to evaluate the predictive value of soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and T cell immunoglobulin and mucin domain-4 (TIM-4) using nomograms, calibration curves, and Receiver Operating Characteristic (ROC) curves.
RESULTS
Out of 96 patients, 20 (20.83%) developed postoperative pulmonary infections. Significant differences were noted between occurrence and non-occurrence groups in terms of smoking (65.00% vs. 34.21%, p = 0.013), surgical duration (70.00% vs. 31.58%, p = 0.002), Preoperative hemoglobin level (35.00% vs. 65.79%, p = 0.013), sTREM-1 levels (23.57 ± 3.16 pg/mL vs. 15.62 ± 2.48 pg/mL, p < 0.001), and TIM-4 levels (61.48 ± 6.35 pg/mL vs. 44.73 ± 5.22 pg/mL, p < 0.001). Logistic regression analysis leads to the development of a risk prediction model for post-gastrointestinal surgery pulmonary infections. The high predictive values of sTREM-1 (Area Under Curve (AUC) = 0.962, 95% confidence interval (CI) 0.917~0.999) and TIM-4 (AUC = 0.970, 95% CI 0.925~1.000) were highlighted by the AUC values, underscoring their clinical importance.
CONCLUSIONS
A predictive model utilizing sTREM-1 and TIM-4 for pulmonary infection following gastrointestinal surgery was developed. Additionally, other risk factors such as smoking, surgical duration, and preoperative hemoglobin level were evaluated. This finding can be applied in clinical practice to identify potentially susceptible patients and facilitate early intervention measures.

AIM
Aspergillosis is the most common invasive fungal infection among lung transplant recipients (LTRs). Although its incidence is lower than that of bacterial or viral infections, it poses a similar or even higher mortality rate due to challenges in early diagnosis, limited treatment options, and various complications. Therefore, we aimed to evaluate the pulmonary aspergillosis cases in our tertiary lung transplant center.
METHODS
A retrospective analysis of 146 LTRs was performed. The demographic data, microbiological and histopathological test results, and radiological findings used for Aspergillus identification were recorded.
RESULTS
Aspergillus spp. was detected in 13 of 146 LTRs (9%), mean age 42.5 ± 14.06 years, an average of 18.9 months after lung transplantation. 3 cases (23%) had Aspergillus growth in tissue culture, and 2 (15.4%) showed fungal elements with septal hyaline fibrils in tissue pathology. Aspergillus spp Polymerase chain reaction (PCR) was positive in bronchoalveolar lavage of 8 (61.5%) cases. In addition, 4 (30.7%) cases had relevant tomography findings. The most common pathogens were A. Terreus (21%), A. Fumigatus (14%), and A. Flavus (14%). The mortality rate was 15%.
CONCLUSIONS
LTRs are at high risk of Aspergillus spp infections. Early diagnosis with microbiological, histopathological, and radiological tests, in addition to well-established prevention strategies, prophylaxis, and treatment will provide a better survival rate for patients.
