Rapid tests for post-mortem examinations have been researched and currently have several applications. In the present study, we aimed to test the performance of O.K.N.V.I. RESIST-5 tests on impure post-mortem biological samples compared with a standard of pure cultures. When a death occurs during hospitalization and the issue of malpractice arises, the medico-legal practice would benefit from rapid tests applicable to post-mortem samples. Thus, detection and differentiation of the five targeted carbapenemases, namely oxacilinase-48, <i>Klebsiella pneumoniae</i> carbapenemase, New Delhi metallo-β-lactamase, Verona integron-encoded metallo-β-lactamase and imipenemase, could be useful in guiding sampling for third-party microbiological assessment and could also be an asset from an epidemiological standpoint. The present prospective and observational pilot study included medico-legal autopsy cases performed at Mina Minovici National Institute of Legal Medicine (Romania) between June and July 2022. A total of two sets of O.K.N.V.I. RESIST-5 tests were performed: Test I, which was performed on-site from biological samples obtained during autopsy; and Test II, which was performed on pure cultures after sample inoculation and incubation. Total of 39 O.K.N.V.I. RESIST-5 rapid tests were performed on 19 biological samples, at least one sample per case. The O.K.N.V.I. RESIST-5 tests performed on-site showed an overall sensitivity of 92.3% with a 100% specificity. The results obtained through rapid tests using post-mortem impure samples were comparable to the results obtained from sample cultures with good sensitivity and specificity. Through post-mortem screening for carbapenem resistance, it would be possible to narrow down the number of cases that require further bacteriological assessment.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"73 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2023-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138825953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pseudoaneurysms are rare vascular lesions formed by damage to the arterial wall that can occur after trauma or postoperatively, causing uncontrolled bleeding. The present report describes a case of a pseudoaneurysm that occurred after SSRO in a 22‑year‑old female patient. Le Fort I osteotomy and bilateral SSRO were performed under general anesthesia to improve the gummy smile and mandibular asymmetry of the patient. While osteotomizing the medial side of the left SSRO, major bleeding occurred from the soft tissue of the posterior margin of the mandibular branch. Direct compression with gauze and a local hemostatic agent stopped the bleeding. Immediately after returning to the ward, bleeding was observed from the left wound site and marked swelling of the left buccal area occurred. Contrast‑enhanced computed tomography revealed a pseudoaneurysm of the left superficial temporal artery (STA). Subsequently, arterial embolization for the pseudoaneurysm was performed. Overall, the present report describes a rare case of pseudoaneurysm of the STA as a postoperative complication of SSRO.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"9 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134992148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While COVID‑19 is primarily recognized for its respiratory impact, it may also affect other organs, including the brain. One notable aspect of COVID‑19 is its association with coagulopathy, an abnormal condition of blood clotting. Coagulopathy may result in various complications, including neurological ones such as stroke. The study analyzed data obtained from patients admitted to a neurology department who had confirmed neurological pathologies along with COVID‑19. It specifically examined the cases of three patients with neurological conditions and COVID‑19, discussing their risk factors and how their conditions progressed clinically. The study concluded that COVID‑19 infection increases the likelihood of stroke, particularly within the initial 10 days after infection. CVT in particular is strongly linked to COVID‑19 and its underlying mechanisms involve immune systemic processes, cytokine storms, increased blood thickness, thrombogenesis, hypercoagulability and inflammation. The presence of SARS‑CoV‑2 infection may worsen the procoagulant cascade, thereby affecting the clinical condition of patients with CVT. The study underscores the importance of recognizing this uncommon but treatable consequence of COVID‑19 infection. Furthermore, it highlights the uniqueness of the study in evaluating COVID‑19 infection in patients with CVT from Romania and South‑East Europe. The findings support the existence of neurological disorders, including clotting complications in the brain's sinuses and vessels, in individuals infected with SARS‑CoV‑2. Several risk factors contribute to the development of CVT, such as infections, oral contraceptives, pregnancy, hematological disorders, trauma, autoimmune disorders and malignancies.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"47 12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134901885","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, CO₂ laser therapy has been used for managing GSM but without high quality evidence. The present review assessed the effectiveness of CO₂ laser therapy in the management of GSM.

The outcomes of interest included Female Sexual Function Index (FSFI), Vaginal Health Index (VHI) and visual analog scale (VAS) for dyspareunia, dryness, burning, itching and dysuria. A total of seven RCTs were included in the review and meta‑analysis, with 6/7 studies using three sessions of laser therapy, 4‑8 weeks apart. Meta‑analysis demonstrated no statistically significant difference in FSFI [mean difference (MD), ‑1.48; 95% CI, ‑5.85, 2.89; I²=45%] and VHI scores (MD, ‑0.18; 95% CI, ‑1.66, 1.31; I² =72%) between laser and control groups.

The present study aimed to explore the effects of butorphanol on a neurodegenerative disease cell model and to investigate its specific regulatory mechanism. Cell viability of PC12 cells was assessed using the Cell Counting Kit‑8 assay. Oxidative stress levels were measured by the corresponding kits and western blotting of specific protein markers. Apoptosis was determined using the terminal‑deoxynucleoitidyl transferase mediated nick end labeling assay and by western blotting. Western blotting was used to analyze the expression levels of c‑Jun NH2‑terminal kinase (JNK)/p38 signaling pathway‑related proteins. Thiobarbituric acid‑reactive substances and Fe⁺² content were detected using the corresponding assay kits and the expression levels of ferroptosis‑associated proteins were assessed by western blotting following the addition of the JNK activator anisomycin (ANI). Oxidative stress and apoptosis were examined with the aforementioned assays following the supplementation of ANI or the ferroptosis inducer erastin (ERA). It was revealed that butorphanol dose‑dependently enhanced the viability and suppressed the oxidative stress and apoptosis of H₂O₂‑treated PC12 cells. In addition, butorphanol blocked JNK/p38 signaling and hampered ferroptosis, while this effect was reversed by ANI. ANI or ERA reversed the effects of butorphanol on oxidative stress and apoptosis of H₂O₂‑treated PC12 cells. In summary, butorphanol suppressed ferroptosis by blocking JNK/p38 signaling to impart inhibitory effects on oxidative stress and apoptosis in a neurodegenerative disease cell model.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"108 36","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135137105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MicroRNAs (miRs) have been identified as key regulators of immune homeostasis. B‑cell lymphoma/leukemia 10 (BCL10) has been implicated in the activation and suppressive function of regulatory T cells (Tregs). This study aimed to investigate the potential role of miR‑155‑5p in modulating the activation and function of Tregs in MG. To achieve this objective, blood samples were collected from MG patients to assess the expression levels of miR‑155‑5p and BCL10, as well as the proportion of circulating Tregs, in comparison to healthy controls. The correlation between miR‑155‑5p and BCL10 levels was evaluated in human samples. The expression levels of miR‑155‑5p and the numbers of circulating Tregs were also examined in an animal model of experimental autoimmune MG (EAMG). A dual‑luciferase reporter assay was used to verify whether miR‑155‑5p can target BCL10. To determine the regulatory function of BCL10 in Tregs, CD4+ CD25+ Tregs were transfected with either small interfering‑BCL10 or miR‑155‑5p inhibitor, and the expression levels of the anti‑inflammatory cytokine IL‑10 and transcription factors Foxp3, TGF‑β1, CTLA4, and ICOS were measured. The results demonstrated that the expression level of miR‑155‑5p was significantly higher in patients with MG compared with that in healthy controls, whereas the expression level of BCL10 was significantly decreased in patients with MG. Furthermore, there was a significant negative correlation between the expression levels of miR‑155‑5p and BCL10. The number of circulating Tregs was significantly reduced in patients with MG and in the spleen of rats with EAMG compared with that in the corresponding control groups. The dual‑luciferase reporter assay demonstrated that miR‑155‑5p could target BCL10. The Tregs transfected with si‑BCL10 demonstrated significant decreases in the protein levels of TGF‑β1 and IL‑10, as well as in the mRNA expression levels of Foxp3, TGF‑β1, CTLA‑4 and ICOS. Conversely, the Tregs transfected with the miR‑155‑5p inhibitor exhibited a substantial increase in these protein and mRNA expression levels compared with their respective control groups. Furthermore, the knockdown of BCL10 exhibited a decline in the suppressive efficacy of Tregs on the proliferation of CD4⁺ T cells. Conversely, the suppression of miR‑155‑5p expression attenuated the inhibition of the BCL10 gene, potentially causing an indirect influence on the suppressive capability of Tregs on the proliferation of CD4⁺ T cells. BCL10 was thus found to contribute to the activation and immunosuppressive function of Tregs. In summary, the present study demonstrated that miR‑155‑5p inhibited the activation and immunosuppressive function of Tregs by targeting BCL10, which may be used as a future potential target for the treatment of MG.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":" 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135242352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, no standardized method has been proposed to tackle this issue. The effects of pelvic floor myofascial manipulation intervention during the second stage of labor in primiparas and its prognostic value in neonatal postpartum outcomes remain unknown. In the present study, a total of 60 primiparas who were expecting a vaginal delivery in the Second Affiliated Hospital of Hainan Medical College (Haikou, China) between October 2021 and January 2022 were selected. These women were randomly assigned to a control group (standard intrapartum care) or an experimental group (pelvic floor myofascial manipulation for 15‑20 min during the second stage of labor along with standard intrapartum care) using a random number table, with 28 patients in each group. There was no significant difference in age, gestational time or body mass index between the two groups before delivery, indicating that the baseline data were comparable. The second stage of labor duration, forced breath‑holding time and postpartum hemorrhage volume in the experimental group were significantly lower than those in the control group. The pain visual analog scale scores, fatigue scores and neonatal Apgar scores in the experimental group were also significantly lower than those in the control group. The rate of episiotomy in the experimental group was lower than that in the control group, but the difference was not statistically significant. In conclusion, pelvic floor myofascial manipulation intervention during the second stage of labor for primiparas with vaginal delivery can reduce the duration of the second stage of labor, the amount of bleeding during labor and the pain during labor.
