Background. Long noncoding RNAs (lncRNAs) often facilitate cellular communication via exosomes. However, their specific roles in head and neck squamous cell carcinoma (HNSCC) are not well understood. Methods. We extracted data on exosome-related lncRNAs from exoRBase and collected transcriptional profiles and clinical details for HNSCC from the TCGA database. Data preprocessing and analyses incorporated Tumor Mutation Burden and Microsatellite Instability from Researcher’s Home and drug sensitivity information from Genomics of Drug Sensitivity in Cancer database. We developed a prognostic model using Cox regression and LASSO regression analysis, with subsequent multivariate analysis to identify significant prognostic indicators. We also constructed a nomogram to evaluate the model’s clinical relevance, performed Gene Set Enrichment Analysis (GSEA), and analyzed the immune microenvironment and therapy sensitivity using CIBERSORT and TIDE algorithms. Supporting in vitro experiments and statistical analyses were conducted. Results. Our comprehensive investigation revealed 17 exosome-associated lncRNAs critical for patient survival in HNSCC. This enabled the development of a prognostic model that effectively stratifies patients into high-risk and low-risk categories. These lncRNAs correlate with patient demographics and clinical characteristics such as age, gender, and tumor stage. GSEA highlighted significant gene expression differences between the risk groups, particularly in pathways related to muscle formation, cellular transition, and immune response. The analysis of the immune microenvironment showed distinct immune cell infiltration patterns in high-risk patients, indicative of compromised immune defenses. In addition, we explored the expression of critical immune checkpoints and their impact on immunotherapy efficacy, demonstrating that risk scores may predict treatment responses. Notably, LINC01564 was overexpressed in HNSCC, associated with poorer prognosis, enhanced xenobiotic metabolism, and altered immune cell infiltration. Experimental validation confirmed LINC01564’s role in promoting tumor cell proliferation, invasion, and migration, highlighting its therapeutic potential. Conclusions. Our study highlights the importance of exosome-associated lncRNAs in HNSCC, identifying 17 critical lncRNAs as vital prognostic markers. The upregulation of LINC01564, associated with poor outcomes and increased tumor aggressiveness, underscores its potential as a therapeutic target.

Diabetes nephropathy (DN) is increasingly recognized as a critical complication in individuals with diabetes and a significant contributor to end-stage renal disease (ESRD). Bailing capsules, which contain fermented cordyceps mycelium, are commonly utilized in treating various kidney disorders, including DN in clinical practice. This review aims to comprehensively detail the pharmacologically active components of Bailing, its mechanisms of action, and its clinical usage. By employing network pharmacology, we delve into the possible pathways Bailing impacts DN treatment. Current studies suggest that Bailing’s efficacy in DN primarily involves mechanisms related to lipid and atherosclerosis, cancer pathways, and small-cell lung cancer. Key active ingredients in Bailing that contribute to its therapeutic effects include arachidonic acid, linalyl acetate, β-sitosterol, and CLR. Furthermore, for literature selection in this review, we integrated GPT-4 with bias analysis coprocessing. This evaluation provides a foundational understanding and direction for future research into the use of Bailing as a novel treatment for DN.

Background. An outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) epidemic occurred throughout China from December 2022 to January 2023, and the vast majority of those infected individuals were mild. The symptom characteristics of mildly infected individuals in this epidemic wave of the Omicron variant have not been well described. Methods. We conducted a nationwide survey of symptomatic characteristics of nonhospitalized individuals with mild Omicron infection through a WeChat app. Results. Respondents (68.6% female) were aged 18–87 years (42.6 ± 13.1 years), of whom 79.8% were diagnosed by SARS-CoV-2 PCR or antigen test. Of the 19 symptoms predefined in the questionnaire, an average of 7.8 symptoms was reported. The most common symptoms included cough (81.2%), fever (79.9%), fatigue (73.8%), muscle soreness (62.2%), headache (59.2%), and phlegm (55.1%). Painful swallowing was present in 38.3% of the participants and was one of the most severe symptoms perceived by the participants. Also, we found that young people were more likely to have symptoms such as fever, painful swallowing, and headache compared to the elderly population. 36.9% of respondents graded their symptoms as severe, and the severity of symptoms was higher in young people than in older adults, with fever, cough, painful swallowing, fatigue, and headache being the most severe. In addition, women experienced a significantly higher prevalence of symptoms than men, but there was no significant difference in the severity of most symptoms. The presence of comorbidities did not increase the incidence or severity of symptoms in those with mildly infected individuals. Conclusions. The symptom profile of mild COVID-19 cases in the nationwide Omicron wave in China was markedly different from previous reports, featuring a high incidence of symptoms, multiple symptoms, and heavy symptoms. The symptoms of mild Omicron infection cases are not mild and are more pronounced in young people.

Background. Globally, imprudent consumption practices contribute to the widespread threat of antimicrobial resistance (AMR). Standardized monitoring of antibiotic use is essential to combat AMR, yet few studies in sub-Saharan Africa, including Ethiopia, have utilized the World Health Organization (WHO) point-prevalence survey (PPS) methodology to examine antimicrobial use. Our setting lacks sufficient national data on this issue. This study aimed to examine the prevalence of antimicrobial use, common antimicrobial drug types, and indications for antimicrobial use in a major public hospital. Methodology. A cross-sectional PPS study design conducted in a hospital setting was utilized to explore the usage of antimicrobials in the adult wards of Felege Hiwot Comprehensive Specialized Hospital (FHCSH), employing the WHO-PPS methodology. The research was carried out between December 24th and 26th, 2022. All patients present in a hospital ward at 8 : 00 am on the designated survey day were included. Data were gathered through a combination of reviewing patients′ medical records and conducting interviews with the attending physicians. Results. A total of 410 hospitalized patients were surveyed, out of which 258 (62.9%) patients were treated with at least one antimicrobial on the date of PPS. All antimicrobials were prescribed empirically. The most common indication for the therapeutic use of antimicrobials was community-acquired infections (166, 64.3%). The top three wards with a large number of antimicrobial prescriptions were the surgical (158, 42.5%), medical (144, 38.7%), and gynecology (55, 14.8%) wards. Ceftriaxone was the most frequently used antibiotic (35%) in all the wards. The mean number of antimicrobials prescribed to the patient was 1.44. Of the prescribed 372 antimicrobials, 60.1% belonged to the WHO watch group. Conclusion. Our findings indicate that a significant number of patients received at least one antimicrobial during the point-prevalence survey (PPS). Empirical prescriptions for community-acquired infections were prevalent. These results underscore the need for robust antimicrobial stewardship programs in Ethiopian hospitals.

Oleuropein is the main compound in olives, producing a relatively bitter taste for unprocessed and raw olives. It has been dramatically applied in herbal and traditional medicine and contains several biological functions, anti-inflammatory effects, antimicrobial characteristics, and anticancer and antioxidant activities. The present study dealt with the cytotoxic effect, reactive oxygen species (ROS) suppressor, and wound-healing activity of oleuropein on normal skin cells. Oleuropein’s cytotoxic and apoptotic effects were evaluated using MTT, flow cytometry, and DAPI staining. Moreover, oleuropein’s possible free radical scavenging properties were studied through several methods, including the 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ABTS tests. The scratch assay was performed for wound-healing features, and qRT-PCR evaluated the expression of apoptosis-associated genes. Oleuropein was found to have a cytotoxic effect on skin cells at higher exposure doses. Apoptosis was induced in the flow cytometry histogram of the cells treated with oleuropein. The results also revealed the strong anti-inflammation and antioxidant effect of oleuropein. They suggested that more studies are necessary to assess the possible pharmacological use of oleuropein to prevent or decrease skin-related diseases.

Objective. To assess the effectiveness of atrioventricular valve regurgitation (AVVR) detection using color Doppler in the four-chamber view (4CV) for identifying atrioventricular septal defects (AVSDs) during 11–13 + 6 weeks’ gestation. This study compares AVVR detection to conventional 2D ultrasound and investigates associations between AVSD and increased nuchal translucency thickness (NT), as well as additional cardiac, extracardiac, and chromosomal abnormalities in the first trimester. Materials and Methods. This prospective study analyzed data from singleton pregnancies diagnosed with AVSD at 11–13 weeks gestation. It included routine ultrasound examinations focusing on fetal anatomy, NT measurement, and blood flow analysis across AVVR using both color and directional power Doppler. Evaluations targeted the 4CV and the three-vessel and trachea views (3VT). Ratios such as LAVV/RAVV and main pulmonary artery-to-aorta (PA/AO) diameter were also calculated. Results. Over three years, 452 fetuses were diagnosed with congenital heart disease in the first trimester, including 25 cases of AVSD (21 complete, 1 partial, and 3 intermediate). Seventeen cases were isolated AVSDs, 13 associated with heterotaxia syndrome, one with tetralogy of Fallot, and two survived. Among these, 92% showed AVVR, 61.54% had NT above the 95th percentile, and 32.0% lacked a nasal bone. AVVR was a more reliable indicator of AVSD than other ultrasonic markers. Conclusion. AVSD exhibits a diverse range of clinical presentations. A comprehensive review of both intracardiac and extracardiac anomalies is essential. AVVR detected during NT scanning in the first trimester can confirm the presence of AVSD.

Background. With the advent of direct-acting antiviral agents, the rate of sustained virological response in the treatment of hepatitis C virus (HCV) infection has reached 100%. However, it has been observed that many patients still do not have access to treatment. Aim. The aim of this study was to identify patients who are anti-HCV and HCV-RNA-positive, to reveal undiagnosed cases, and thus to reveal the necessity of increasing HCV follow-up tests and diagnosis. Methods. The microbiology database of Tepecik Research and Training Hospital was examined for patients who were tested for anti-HCV and HCV-RNA from January 2013 to January 2023. Patients were indexed based on their entry date, and duplicate values were manually removed. The data were then grouped according to the clinics that requested the analysis. Results. Between 2013 and 2023, a total of 334,537 anti-HCV tests were conducted without duplications. The annual average number of tests was 33,454 ± 10,027. During the ten-year period under review, the total number of patients with a positive result for the anti-HCV test was 3,943. The positivity rate among all anti-HCV tests was 1.18%. The annual average number of positive test results was 394 ± 54. Between 2013 and 2022, out of the 3,943 patients who tested positive for anti-HCV, HCV-RNA analysis was conducted on 2,500 of them (63.4%). Among the 2,500 patients who underwent HCV-RNA analysis, 682 were found to be HCV-RNA-positive (27.4%), while 1,818 were HCV-RNA-negative (72.6%). In the ten-year period, when the distribution of the 334,537 anti-HCV tests according to internal and surgical branches was evaluated, it was found that 157,680 tests (47.1%) were requested from internal branches, while 176,857 tests (52.9%) were requested from surgical branches. Of the 2,500 patients who tested positive for anti-HCV and underwent HCV-RNA analysis, 2,273 (90.9%) were requested by internal branches, while surgical branches requested 227 tests (9.1%). Among the 1,443 patients who tested positive for anti-HCV but did not have HCV-RNA tests ordered, 788 (54.6%) were evaluated in internal branches, and 655 (45.4%) were evaluated in surgical branches. Conclusion. In this study, it was observed that multiple anti-HCV tests were requested for the same individual, and HCV-RNA tests were not ordered for those testing positive for anti-HCV. Moreover, patients were not referred to the infection or gastroenterology clinics for HCV-RNA testing. Consequently, it was concluded that sufficient and necessary tests for diagnosis were not conducted, leading to the inability to access treatment. To achieve the World Health Organization’s goals for HCV eradication, it is imperative to increase the rates of HCV-RNA testing, enhance the utilization of reflex testing, and ensure proper referral to the necessary clinics.

Background. Liver injury related to heatstroke plays a pivotal role in secondary multiorgan damage and is a direct cause of mortality in affected patients of heatstroke. This study was designed to identify independent risk factors associated with liver injury in heatstroke and to construct a clinically applicable predictive model. Methods. We conducted a retrospective analysis of 188 patients diagnosed with heatstroke, treated in the emergency departments of eight medical institutions from July 1, 2022, to September 30, 2023. Patients were categorized into a liver injury group (n = 80) and a nonliver injury group (n = 108), based on liver function indices recorded during hospitalization. Lasso regression was employed for variable refinement, while multifactorial logistic regression was utilized to identify independent risk factors for liver injury in heatstroke and to construct a nomogram model. The model’s efficacy was evaluated using the C-index, calibration curves, and decision curve analysis, examining its discriminative ability, calibration, and clinical utility. Results. The nomogram included predictive factors such as the Glasgow score, absolute lymphocyte count, lactate dehydrogenase levels, and creatine kinase isoenzyme. The model showed high accuracy and discriminative capability. The C-index was 0.852 (95% CI 0.80–0.905) with a calibration index of 0.843. Decision curve analysis revealed significant clinical applicability for this nomogram. Conclusion. The study identified four key independent risk factors for liver injury in heatstroke patients. The constructed nomogram, based on the four clinical indicators, demonstrated robust predictive accuracy, discriminative power, and clinical relevance.

Background. The pineal region represents significant challenges in terms of neurosurgery. Currently, anatomical research that simulates surgery for the endoscopic keyhole approach to the pineal region is lacking. This study aims to summarize the exposure range and operational characteristics of total endoscopic surgery under the four supratentorial and infratentorial keyhole approaches, through rigorous quantitative anatomical research. We also aim to understand the surgical exposure characteristics and surgical feasibility under each approach. Method. Six wet cadaveric head specimens (a total of 12 sides) were subjected to simulated surgery with a keyhole bone window size of approximately 3 × 4 cm. The median endoscopic supracerebellar infratentorial approach (M-ESCITA), the paramedian endoscopic supracerebellar infratentorial approach (PM-ESCITA), the endoscopic occipital transtentorial approach (EOTA), and the endoscopic interhemispheric high occipital transtentorial approach (EHOTA) were used to measure the surgical path depth, maximum distance between the tentorial margins, maximum operable area, operable angle, and relative degree of freedom of each approach. Results. There was no difference in the exposure range of the surgical area. The surgical path of PM-ESCITA was the longest (p < 0.001), and its horizontal operating angle was the largest (p < 0.001), whereas the anteroposterior operating angle of EHOTA was the largest (p < 0.001). The maximum operational area of M-ESCITA was the largest in the pineal region (p < 0.01), whereas that of EHOTA was the largest in the tetrapod region (p < 0.001). M-ESCITA had the highest relative degree of freedom during surgery at the pineal gland level (p < 0.001), PM-ESCITA at the splenium of the corpus callosum (p < 0.01), and EHOTA at the corpora quadrigemina (p < 0.001). Conclusions. Each of the four endoscopic keyhole approaches has its own advantages. Through anatomical research, doctors can train themselves and master the differences in surgical procedures through different approaches. The choice of approach and surgical challenge are dependent on the microsurgical techniques employed by the surgeon. A balance between minimally invasive and safe endoscopic surgery should be pursued.
