In total, 758 patients with hip fractures attending the Department of Orthopedics and Traumatology, Kütahya Health Sciences University Faculty of Medicine (Kütahya, Turkey) between January 2016 and January 2023 were included in the present study. Patients were then divided into two groups, namely the mortality (n=464; 61.2%) and survivor (n=294; 38.8%) groups. Patients in the mortality group were further sub-divided into the following three subgroups: i) Those who succumbed in <1 month (n=117; 25.2%); ii) those who succumbed between 1 and 12 months (n=185; 39.9%); and iii) those who succumbed >12 months later (n=162; 34.9%). In addition, the RDW coefficient of variation, mean platelet volume (MPV), MPV/platelet ratio, neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio (PLR), mean platelet volume-to-lymphocyte ratio and monocyte-to-eosinophil ratio means were all found to be significantly higher in the mortality group (P<0.05). MPV (P<0.01), HGB (P<0.05), eosinophil, EOS (P<0.01), HRR (P<0.01), and PLR (P<0.05) were all revealed to exert significant effects on mortality. An age cut-off of 74.50 years had a sensitivity of 81.5% and specificity of 37.1%, whereas an MPV cut-off of 8.85 yielded a sensitivity of 73.5% and specificity of 36.1%. By contrast, an HGB cutoff of 11.05 had a sensitivity of 55.6% and specificity of 35.7%, an eosinophil cut-off of 0.065 had a sensitivity of 47.6% and specificity of 35.4%, whilst a HRR cut-off of 0.7587 had a sensitivity of 55.2% and specificity of 30.3%. Furthermore, a PLR cut-off of 152.620 had a sensitivity of 67.2% and specificity of 41.8% for hip fracture-associated mortality. An age cut-off of 79.50 years had a sensitivity of 70.9% and specificity of 41.5%, while an age cut-off of 83.50 years had a sensitivity of 46.2% and specificity of 64.0% for mortality occurring <1 month after hip fractures. To conclude, results from the present study suggested that HRR has potential predictive value for hip fracture-associated mortality and 30-day mortality, whereas the PLR could only predict hip fracture-associated mortality.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"29 1","pages":"414"},"PeriodicalIF":2.7,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249731","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}

Whilst cognitive impairment can be easily diagnosed in the more advanced stages of neurodegenerative diseases, early detection can be challenging. This is mainly the consequence of the incomplete understanding of the underlying pathophysiological mechanisms. In addition, currently available neurological treatments do not specifically target cognitive decline, since other motor and non-motor symptoms, such as bradykinesia, tremor, autonomic disturbances and depression, are of greater relevance from a therapeutic perspective. In this context, prospective studies must address a number of issues, including the risk factors associated with cognitive deficits in neurodegenerative diseases. The present review aims to offer a novel perspective on the association between Epstein-Barr virus infection and cognitive decline found in patients with neurodegenerative disorders. Specifically, relevant epidemiological studies and clinical trials explaining this connection were reviewed, focusing on the most frequent neurodegenerative disorders. They are namely Alzheimer's disease, Parkinson's disease and multiple sclerosis. Despite their limitations, possible underlying pathophysiological mechanisms that explain the impact of Epstein-Barr virus infection on cognitive decline are expected to offer novel study directions on this clinically relevant topic.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"2 1","pages":"413"},"PeriodicalIF":2.7,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249733","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}

Key word-based advanced searches were executed using the aforementioned databases. A total of 45 studies that reported the prescriptions of off-label and unlicensed drugs to pediatric patients were included. The global prevalence of off-label and unlicensed drug prescriptions to children in pediatrics or neonatal departments was 56%. Patient sample sizes varied from 40-13,426, with a range of 240-8,891 total prescriptions issued. Of the 45 studies examined, 22 studies originated from Europe, 13 from Asia, 3 from South America, 3 from Africa, and 2 each from North America and Australia. Africa had the highest prevalence rate at 66%, followed by Asia, South America, North America, Australia and Europe.

Under current medical conditions, instrument separation cannot be completely avoided because of the complex morphology of root canals and the limited surgical field and operating space of the surgeon. FIs, especially those broken in the apical third of the canal, render it difficult to completely remove infection in the root canal, where the residual infection can easily develop into reinfection. The removal of FIs is therefore the preferred option for the majority of clinicians in such cases. However, root canal preparation instruments are frequently fractured during treatment because of the complex root canal morphology, such as curvature or severe calcification, which further increases the difficulty of instrument removal. In the present case, a 41-year-old female patient complained of worsening pain in the left maxillary first molar for 3 days. This patient had been treated at another hospital 2 years earlier, but the discomfort persisted after treatment. Preoperative periapical radiography revealed suspected FIs at the apical third of the mesiobuccal (MB) root and the middle third of the distal buccal (DB) root, underfilling of the palatal (P) root canal and large hypodense areas surrounding the periapical region of all roots. Next, the micro-ultrasound technique was used to remove the FI in the DB canal; a bypass through the second MB canal (MB2) was created to fill the apical stop of the MB root and the P canal was retreated. The therapeutic effect of the bypass technique was assessed by comparing bypass treatment and removal treatment for endodontic FIs. The 9-month and 27-month follow-ups revealed that the periapical inflammation surrounding the DB root treated after removal of the FI and the MB root treated by bypass was significantly controlled compared with that before the operation. In addition, the present report reviewed the research progress in bypass and removal techniques, focusing on the difficulties and key points of successful root canal therapy.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"8 1","pages":"411"},"PeriodicalIF":2.7,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142223650","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}

Patients diagnosed with AF and left atrial appendage thrombosis post-successful thrombolysis (n=92) were retrospectively analysed. They were divided into two groups: Group A received radiofrequency ablation combined with an anticoagulant, while Group B received an anticoagulant alone and in combination with antiarrhythmic drugs. Subgroup analyses were conducted based on left atrial diameter (>45 mm), duration of AF (>1 year) and types of anticoagulants. Univariate and multivariate logistic regression analyses were performed to assess stroke and mortality risks in patients with AF with left atrial appendage thrombosis after dissolution. Multivariate logistic regression analysis identified AF duration (>1 year), left atrial diameter (>45 mm) and BNP level as significant risk factors for stroke (P<0.05). Compared with NOACs, the traditional anticoagulants (warfarin) demonstrated higher survival rates and lower stroke incidence in Group B (P<0.05); however, no significant difference was observed within Group A (P>0.05). Radiofrequency ablation combined with anticoagulants appeared to be more effective in treating AF with left atrial appendage thrombosis post-dissolution compared with anticoagulants alone. Attention to AF duration and left atrial diameter is crucial during early patient management. However, the choice between warfarin or NOACs for patients with AF and left atrial appendage thrombosis warrants further investigation.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"13 1","pages":"407"},"PeriodicalIF":2.7,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249735","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}

Patients with SLE exhibit features of accelerated atherosclerosis. Here, the present study reported a rare case of acute myocardial infarction (AMI) in a male patient diagnosed with SLE. A 29-year-old male with no cardiovascular history was diagnosed with AMI and underwent coronary angiography, which showed a long-extended spiral-shaped dissection of the right coronary artery (RCA). The patient's autoimmune panel tested positive for antinuclear, anti-nuclear ribonucleoprotein/Smith and anti-Sjogren's syndrome A antibodies. The patient was diagnosed with SLE and was administered prednisone, hydroxychloroquine and calcium carbonate therapy. At the 3-month follow-up, a repeat coronary angiography showed no dissection in the RCA. Intravascular ultrasound and optical coherence tomography also showed an isolated atherosclerotic lesion without arterial dissection in the RCA. To the best of our knowledge, this is the first reported case of a male patient with SLE who developed myocardial infarction caused by spontaneous coronary artery dissection (SCAD). The present report may provide new insights into possible future treatments for SCAD. SCAD should be considered in patients with SLE and AMI, particularly in young patients without cardiovascular risk factors. Early diagnosis of SCAD is important to provide accurate therapy that differs from the treatment of AMI caused by atherosclerosis.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"1 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140798630","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}

This response develops away from the primary infection site and results in end-organ damage. The present study aimed to investigate the protective and therapeutic effects on lung and kidney tissue of silymarin (S) and dexmedetomidine (DEX) applied 1 h before and after sepsis induced by the cecal ligation and puncture (CLP) method in rats. A total of 62 rats was randomly divided into eight groups: i) Control (n=6); ii) cecal perforation (CLP; n=8); iii) S + CLP (n=8; S + CLP; S administered 1 h before CPL); iv) CLP + S (n=8; S administered 1 h after CLP); v) DEX + CLP (n=8; D + CLP; DEX administered 1 h before CLP); vi) CLP + D (n=8; DEX administered 1 h after CLP); vii) SD + CLP (n=8; S and DEX administered 1 h before CLP) and viii) CLP + SD (n=8; S and DEX administered 1 h after CLP). After the cecum filled with stool, it was tied with 3/0 silk under the ileocecal valve and the anterior surface of the cecum was punctured twice with an 18-gauge needle. A total of 100 mg/kg silymarin and 100 µg/kg DEX were administered intraperitoneally to the treatment groups. Lung and kidney tissue samples were collected to evaluate biochemical and histopathological parameters. In the histopathological examination, all parameters indicating kidney injury; interstitial edema, peritubular capillary dilatation, vacuolization, ablation of tubular epithelium from the basement membrane, loss of brush border in the proximal tubule epithelium, cell swelling and nuclear defragmentation; were increased in the CLP compared with the control group. Silymarin administration increased kidney damage, including ablation of tubular epithelium from the basement membrane, compared with that in the CLP group. DEX significantly reduced kidney damage compared with the CLP and silymarin groups. The co-administration of DEX + silymarin decreased kidney damage, although it was not as effective as DEX-alone. To conclude, intraperitoneal DEX ameliorated injury in CLP rats. DEX + silymarin partially ameliorated injury but silymarin administration increased damage. As a result, silymarin has a negative effects with this dosage and DEX has a protective effect. In the present study, it was determined that using the two drugs together had a greater therapeutic effect than silymarin and no differences in the effects were not observed any when the application times of the agents were changed.","PeriodicalId":12285,"journal":{"name":"Experimental and therapeutic medicine","volume":"11 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2024-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140798628","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}
