Review
Species of the genus Codonopsis (Campanulaceae) have a long history of application, acclaimed for its edible and therapeutic attributes. Scholarly inquiries into Codonopsis span botany, phytochemistry, quality assurance, pharmacodynamics, and toxicity, revealing a rich and comprehensive body of knowledge. This study synthesizes information from esteemed scientific databases like SciFinder, PubMed, China National Knowledge Infrastructure, and Chinese herbal classics to create a thorough scientific conceptual and theoretical framework for Codonopsis research. In this article, the phytochemical composition includes saccharides, polyacetylenes, polyenes, flavonoids, alkaloids, lignans, terpenoids, and organic acids was summarized. To date, over 350 monomeric compounds have been isolated and identified from Codonopsis, with recent studies primarily focusing on polysaccharides, aromatic derivatives, lignans, and polyacetylenes. Codonopsis exhibits broad pharmacological activities across various systems, including immune, blood, cardiovascular, central nervous, and digestive systems, with no significant toxicity or adverse effects reported. The existing research, focusing on various extracts and active parts without identifying specific active molecules, complicates the understanding of the mechanisms of action. There is an urgent need to advance research on the chemical composition and pharmacological effects to fully elucidate its pharmacodynamic properties and the basis of its material composition. Such efforts are crucial for the rational development, utilization, and clinical application of this herb.

Pelvic fractures present a severe and complex clinical challenge. This study aimed to compare ultrasound-guided ilioinguinal (IIN) and iliohypogastric nerve (IHN) blocks with conventional general anesthesia (GA) in patients undergoing internal fixation surgery for pelvic fractures. A retrospective analysis was conducted on 100 patients equally divided into ultrasound-guided and control groups. The study monitored hemodynamics, intraoperative anesthesia drug usage, postoperative pain levels, and the incidence of adverse reactions between the 2 groups. The ultrasound-guided group underwent ultrasound-guided IHN and IIN blocks combined with GA. The ultrasound-guided group exhibited significant advantages for hemodynamic measurements at specific time points, lower consumption of Propofol and Remifentanil, and reduced pain intensity across all evaluated time intervals (P < .05). The incidence rate of adverse reactions was significantly lower in the ultrasound group (P = .016). Ultrasound-guided anesthesia is a superior alternative to conventional GA for managing pelvic fractures through internal fixation surgery. It offers advantages in terms of hemodynamic stability, drug consumption, postoperative pain management, and adverse reaction reduction.

There has been significant interest in the changes in menstrual cycles following coronavirus disease 2019 (COVID-19) infection or vaccination. This study aimed to investigate the evidence for such changes and their potential risk factors. We used a descriptive study design and gathered data by sharing an online survey questionnaire on social media platforms. The questionnaire included questions regarding sociodemographic factors, menstrual cycle changes, and COVID-19 anxiety. The study population comprised women aged 18 to 49 years from Izmir. All data analyses were performed using Statistical Package for the Social Sciences 21.0. The risk factors influencing menstrual irregularities were determined after the COVID binary logistic regression analysis, including univariate and multivariate models. Among the 465 participants, those with an associate's degree had a significantly higher risk of menstrual irregularities than those with a high school diploma (P = .012). Anxiety scores emerged as a significant risk factor for menstrual cycle irregularities (P = .026). However, neither COVID-19 infection nor vaccination resulted in significant changes in the menstrual cycle characteristics (P > .05). Other sociodemographic variables, such as age, body mass index, and smoking, were not significantly associated with menstrual cycle changes(P > .05). The study findings suggest that educational level and anxiety may play a role in menstrual irregularities, whereas COVID-19 infection or vaccination itself may not directly affect menstrual cycle.

Observational Study
To analyze the risk factors for intraperitoneal sigmoid stoma complications after abdominoperineal resection (APR) surgery to guide clinical practice. Patients who were diagnosed with rectal cancer and underwent APR surgery from June 2013 to June 2021 were retrospectively enrolled. The characteristics of the stoma complication group and the no stoma complication group were compared, and univariate and multivariate logistic analyses were employed to identify risk factors for sigmoid stoma-related complications. A total of 379 patients who were diagnosed with rectal cancer and underwent APR surgery were enrolled in this study. The average age of the patients was 61.7 ± 12.1 years, and 226 (59.6%) patients were males. Patients in the short-term stoma complication group were younger (55.7 vs 62.0, P < .05) and had a more advanced tumor stage (P < .05). However, there was no significant difference between the long-term stoma complication group and the no stoma complication group. Multivariate logistic regression analysis revealed that operation time was an independent risk factor (P < .05, OR = 1.005, 95% CI = 1.000-1.010) for short-term stoma complications. Both the short-term and long-term stoma complication rates in our institution were low. A longer operation time was an independent risk factor for short-term stoma complications after APR surgery.

This study aimed to establish an effective predictive model for postoperative delirium (POD) risk assessment after total knee arthroplasty (TKA) in older patients. The clinical data of 446 older patients undergoing TKA in the Orthopedics Department of our University from January to December 2022 were retrospectively analyzed, and the POD risk prediction model of older patients after TKA was established. Finally, 446 patients were included, which were divided into training group (n = 313) and verification group (n = 133). Logistic regression method was used to select meaningful predictors. The prediction model was constructed with nomographs, and the model was evaluated with correction curve and receiver operating characteristic curve. The logistic regression analysis showed that age, educational level, American Society of Anesthesiologists grade, accompaniment of chronic obstructive pulmonary disease, accompaniment of cerebral stroke, postoperative hypoxemia, long operation time, and postoperative pain were independent risk factors for POD after TKA (P < .05). The nomogram prediction model established. The area under receiver operating characteristic curve of the model group and the validation group were 0.954 and 0.931, respectively. The calibration curve of the prediction model has a high consistency between the 2 groups. The occurrence of POD was associated with age, educational level, American Society of Anesthesiologists grade, accompaniment of chronic obstructive pulmonary disease, accompaniment of cerebral stroke, postoperative hypoxemia, long operation time, and postoperative pain in TKA patients.

Randomized Controlled Trial
BACKGROUND
Combining hydromorphone with ropivacaine in ultrasound-guided erector spinae plane blocks enhances postoperative analgesia and reduces interleukin-6 expression in breast surgery patients.
METHODS
In this study, breast cancer patients undergoing modified radical mastectomy were randomized into 3 groups for anesthesia (30 patients in each group): standard general (group C), Erector Spinae Plane Block (ESPB) with ropivacaine (group R), and ESPB with ropivacaine plus hydromorphone (group HR). Diagnosis: Breast cancer patients. Postsurgery, pain levels, IL-6, anesthetic doses, additional analgesia needs, and recovery milestones were compared to evaluate the efficacy of the ESPB enhancements.
RESULTS
The 3 groups were not significantly different in baseline characteristics, operation time, number of cases with postoperative nausea, and serum IL-6 concentrations at T1 (the time of being returned to the ward after surgery). At T2 (at 6:00 in the next morning after surgery), the serum IL-6 concentration in group HR was significantly lower than that in groups R and C (P < .05); the intraoperative doses of remifentanil, sufentanil, and propofol were significantly lower in groups HR and R than those in group C (P < .05); Groups HR and R had significantly lower visual analog scale scores at T3 (4 hours postoperatively), T4 (12 hours postoperatively), and T5 (24 hours postoperatively) than those in group C (P < .05); the proportions of patients receiving postoperative remedial analgesia were significantly lower in groups HR and R than in group C (P < .05); groups HR and R had significantly lower proportions of patients with postoperative nausea than group C (P < .05); the time to the first anal exhaust and the time to the first ambulation after surgery were significantly shorter in groups HR and R than those in group C (P < .05).
CONCLUSION
Hydromorphone combined with ropivacaine for ESPB achieved a greater postoperative analgesic effect for patients receiving MRM under general anesthesia. The combined analgesia caused fewer adverse reactions and inhibited the expression level of the inflammatory factor IL-6 more effectively, thereby facilitating postoperative recovery. ESPB using hydromorphone with ropivacaine improved pain control post-MRM, reduced adverse effects, and more effectively suppressed IL-6, enhancing recovery.

Prenatal alcohol exposure (PAE) causes cognitive impairment and a distinctive craniofacial dysmorphology, due in part to apoptotic losses of the pluripotent cranial neural crest cells (CNCs) that form facial bones and cartilage. We previously reported that PAE rapidly represses expression of >70 ribosomal proteins (padj = 10-E47). Ribosome dysbiogenesis causes nucleolar stress and activates p53-MDM2-mediated apoptosis. Using primary avian CNCs and the murine CNC line O9-1, we tested whether nucleolar stress and p53-MDM2 signaling mediates this apoptosis. We further tested whether haploinsufficiency in genes that govern ribosome biogenesis, using a blocking morpholino approach, synergizes with alcohol to worsen craniofacial outcomes in a zebrafish model. In both avian and murine CNCs, pharmacologically relevant alcohol exposure (20mM, 2hr) causes the dissolution of nucleolar structures and the loss of rRNA synthesis; this nucleolar stress persisted for 18-24hr. This was followed by reduced proliferation, stabilization of nuclear p53, and apoptosis that was prevented by overexpression of MDM2 or dominant-negative p53. In zebrafish embryos, low-dose alcohol or morpholinos directed against ribosomal proteins Rpl5a, Rpl11, and Rps3a, the Tcof homolog Nolc1, or mdm2 separately caused modest craniofacial malformations, whereas these blocking morpholinos synergized with low-dose alcohol to reduce and even eliminate facial elements. Similar results were obtained using a small molecule inhibitor of RNA Polymerase 1, CX5461, whereas p53-blocking morpholinos normalized craniofacial outcomes under high-dose alcohol. Transcriptome analysis affirmed that alcohol suppressed the expression of >150 genes essential for ribosome biogenesis. We conclude that alcohol causes the apoptosis of CNCs, at least in part, by suppressing ribosome biogenesis and invoking a nucleolar stress that initiates their p53-MDM2 mediated apoptosis. We further note that the facial deficits that typify PAE and some ribosomopathies share features including reduced philtrum, upper lip, and epicanthal distance, suggesting the facial deficits of PAE represent, in part, a ribosomopathy.

Evidence from in vitro and animal models has identified the pulmonary toxicity of flavors in electronic cigarettes (ECIGs); however, less is known from epidemiological studies about the effects of flavors in the respiratory health. This study examined the longitudinal association between exposure to ECIGs flavors and nocturnal dry cough among ECIGs users. A secondary analysis of data from the Population Assessment of Tobacco and Health Study (2014-2019) was conducted. The study population included adults who provided information (n = 18,925) for a total of 38,638 observations. Weighted-incidence estimates and weighted- generalized estimating equation models were performed to assess unadjusted and adjusted associations. The weighted incidence proportion (WIP) of nocturnal dry cough was significantly higher among current (WIP:16.6%; 95%CI 10.5, 21.2) and former fruit flavored ECIGs users (WIP:16.6%; 95%CI 11.3, 21.9) as compared to non-ECIGs users (WIP:11.1%; 95%CI 10.6, 11.6). Current ECIGs users of fruit flavors showed 40% higher risk of reporting cough than non-ECIGs users (aRR:1.40, 95%CI 1.01, 1.94). Former ECIGs users of multiple flavors and other flavors had 300% and 66% higher risk to develop cough, respectively (aRR:3.33, 95%CI 1.51, 7.34 and aRR:1.66, 95%CI 1.0.9, 2.51), relative to non-ECIGs users. We observed a significantly higher risk of developing nocturnal dry cough in the past 12 months in current and former ECIGs users of fruit flavors and in former ECIGs users of multiple flavors. To the extent that cough may serve as an early indicator of respiratory inflammation and potential disease risk, the association between ECIGs use and cough raises potential concerns.

A growing increase in the number of serious infections caused by multidrug resistant bacteria (MDR) is challenging our society. Despite efforts to discover novel therapeutic options, few antibiotics targeting MDR have been approved by the Food and Drug Administration (FDA). Lactic acid bacteria have emerged as a promising therapeutic alternative due to their demonstrated ability to combat MDR pathogens in vitro. Our previous co-culture studies showed Lacticaseibacillus rhamnosus CRL 2244 as having a potent killing effect against carbapenem-resistant Acinetobacter baumannii (CRAB) strains. Here we report that cell-free conditioned media (CFCM) samples obtained from Lcb. rhamnosus CRL 2244 cultures incubated at different times display antimicrobial activity against 43 different pathogens, including CRAB, methicillin-resistant Staphylococcus aureus (MRSA) and carbapenemase Klebsiella pneumoniae (KPC)-positive strains. Furthermore, transwell and ultrafiltration analyses together with physical and chemical/biochemical tests showed that Lcb. rhamnosus CRL 2244 secretes a <3 kDa metabolite(s) whose antimicrobial activity is not significantly impaired by mild changes in pH, temperature and various enzymatic treatments. Furthermore, sensitivity and time-kill assays showed that the bactericidal activity of the Lcb. rhamnosus CRL 2244 metabolite(s) enhances the activity of some current FDA approved antibiotics. We hypothesize that this observation could be due to the effects of Lcb. rhamnosus CRL 2244 metabolite(s) on cell morphology and the enhanced transcriptional expression of genes coding for the phenylacetate (PAA) and histidine catabolic Hut pathways, metal acquisition and biofilm formation, all of which are associated with bacterial virulence. Interestingly, the extracellular presence of Lcb. rhamnosus CRL 2244 induced the transcription of the gene coding for the CidA/LgrA protein, which is involved in programmed cell death in some bacteria. Overall, the findings presented in this report underscore the promising potential of the compound(s) released by Lcb. rhamnosus CRL2244 as an alternative and/or complementary option to treat infections caused by A. baumannii as well as other MDR bacterial pathogens.

BACKGROUND
We aimed to determine the rate and impact of post-pericardiotomy syndrome after native valve-sparing aortic valve surgery and the perioperative factors associated with its occurrence.
METHODS
All consecutive patients who underwent native valve-sparing aortic valve surgery (i.e., repair ± ascending aorta replacement, valve-sparing root replacement, Ross procedure ± ascending aorta replacement) at our institution between January 2021 and August 2023 served as our study population. Post-pericardiotomy syndrome was diagnosed if patients showed at least two of the following diagnostic criteria: evidence of (I) new/worsening pericardial effusion, or (II) new/worsening pleural effusions, (III) pleuritic chest pain, (IV) fever or (V) elevated inflammatory markers without alternative causes. A logistic regression model was calculated.
RESULTS
During the study period, 91 patients underwent native valve-sparing aortic valve surgery. A total of 21 patients (23%) developed post-pericardiotomy syndrome early after surgery (PPS group). The remaining 70 patients (77%) showed no signs of post-pericardiotomy syndrome (non-PPS group). Multivariate logistic regression revealed blood type O (OR: 3.15, 95% CI: 1.06-9.41, p = 0.040), valve-sparing root replacement (OR: 3.12, 95% CI: 1.01-9.59, p = 0.048) and peak C-reactive protein >15 mg/dl within 48 hours postoperatively (OR: 4.27, 95% CI: 1.05-17.29, p = 0.042) as independent risk factors. 73% (8/11) of patients displaying all three risk factors, 60% (9/15) of patients with blood type O and valve-sparing root replacement, 52% (11/21) of patients with blood type O and early postoperative peak C-reactive protein >15 mg/dl and 45% (13/29) of patients with early postoperative peak C-reactive protein >15 mg/dl and valve-sparing root replacement developed post-pericardiotomy syndrome.
CONCLUSION
In summary, blood type O, valve-sparing root replacement and peak C-reactive protein >15 mg/dl within 48 hours postoperatively are significantly associated with post-pericardiotomy syndrome after native valve-sparing aortic valve surgery. Particularly, the presence of all three risk factors is linked to a particularly high risk of post-pericardiotomy syndrome.
