Current serum biomarkers for HCC surveillance and early diagnosis, particularly alpha-fetoprotein (AFP) the most commonly used marker, lack satisfactory sensitivity and specificity, highlighting an urgent need for more effective markers with higher accuracy for early HCC detection. The downregulation of melanoma-associated antigen D1 (MAGE-D1) transcription plays a crucial role in apoptosis and inhibits cancer cell proliferation when expressed ectopically. Moreover, reduced MAGE-D1 expression correlates with improved prognosis in many cancers. Therefore, this study aims to evaluate the diagnostic role of MAGE-D1 in HCC, proposing it as a novel biomarker for early diagnosis and monitoring of tumor progression. Serum MAGE-D1 expression was measured using RT-qPCR on 198 subjects, divided into three groups: 88 with HCC, 56 with chronic liver conditions, and 54 as healthy controls. With a sensitivity of 93.3% and a specificity of 97.5%, MAGED-1 shows strong potential as a diagnostic marker for HCC. The performance of serum MAGED-1 expression in discrimination between HCC and chronic liver condition revealed an area under the curve (AUC) of 0.939 using the cutoff (0.752) yielded a sensitivity of 90%, specificity of 85%, and an accuracy of 91%. Evaluation of the diagnostic significance of MAGED-1 demonstrated an AUC value of 0.726, with a sensitivity of 63.6% and a specificity of 73.5%. In conclusion, MAGED-1 might be a specific and sensitive biomarker for HCC, potentially improving the malignancy diagnosis and prognosis.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"35-44"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142381002","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}

Moreover, PTBP1 expression was associated with a poorer prognosis according to risk stratification and a lower CR rate in AML patients. In addition, PTBP1 expression was positively correlated with the expression of the proliferation marker Ki-67 and negatively correlated with the expression of the apoptosis marker p53 in AML patients.

Although initially described in adult patients, the diagnostic definitions for ARDS have evolved over time to accurately describe this disease process in pediatric and, more recently, neonatal patients. The management of ARDS in each age demographic has converged in the application of lung-protective ventilatory strategies to mitigate the primary disease process and prevent its exacerbation by limiting ventilator-induced lung injury. However, differences arise in the preferred ventilatory strategies or adjunctive pulmonary therapies used to mitigate each type of ARDS. In this review, we compare and contrast the epidemiology, common etiologies, pathophysiology, diagnostic criteria, and outcomes of ARDS across the lifespan. Additionally, we discuss in detail the different management strategies used for each subtype of ARDS and spotlight how these strategies were applied to mitigate poor outcomes during the COVID-19 pandemic. This review is geared toward both clinicians and clinician-scientists as it not only summarizes the latest information on disease pathogenesis and patient management in ARDS across the lifespan but also highlights knowledge gaps for further investigative efforts. We conclude by projecting how future studies can fill these gaps in research and what improvements may be envisioned in the management of NARDS and PARDS based on the current breadth of literature on adult ARDS treatment strategies.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"798-818"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141875015","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}

Antiangiogenic proteins such as soluble Fms-like tyrosine kinase-1 (sFLT-1) inhibit the signaling of vascular endothelial growth factor and placental growth factor, resulting in a decrease in the development of new blood vessels. Additionally, they promote the maturation of existing blood vessels and lead to endothelial dysfunction. This study aimed to assess the role of sFLT-1 in adult patients with beta-thalassemia major (TM) as a biomarker of endothelial dysfunction and its association with pulmonary hypertension (PHT). A total of 90 subjects were recruited and categorized into two groups: 45 patients with beta-TM, who were further divided based on the presence or absence of PHT, and 45 healthy individuals served as a control group. Serum sFLT-1 was determined using the enzyme-linked immunosorbent assay technique. The results revealed that Beta-TM patients had higher sFLT-1 levels than the control group. In addition, patients with PHT had significantly higher sFLT-1 levels compared to those without PHT. The levels of sFLT-1 were positively correlated with von Willebrand factor, serum ferritin, and high-sensitivity C-reactive protein. Regression analyses demonstrated a significant association between high sFLT-1 levels and the occurrence of PHT. Additionally, sFLT-1 (at a cutoff value of 8.84 pg/mL) demonstrated a sensitivity of 83.30% and a specificity of 80.0% in diagnosing thalassemic patients with PHT. In conclusion, beta-TM patients with elevated serum levels of sFLT-1 are at risk of developing endothelial dysfunction and subsequent development of PHT.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"883-890"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141875053","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}

Anemia was defined based on World Health Organization criteria, and MDS was calculated considering factors such as the use of diuretics, proton-pump inhibitors, alcohol consumption, and renal function status. A total of 3383 individuals were included in our study. Results showed a positive correlation between MDS and anemia, with higher MDS levels associated with increased anemia prevalence. Subgroup analyses revealed that this association was consistent across different genders, poverty income ratio, and smoking populations, with a notably strong correlation in the non-Hispanic White group. The study suggests that improving the bioavailability of magnesium to reduce MDS may be a factor in preventing anemia in the elderly. This is the first study to explore the relationship between MDS and anemia in this population, highlighting the potential role of magnesium bioavailability in anemia prevention.

Ferulic acid, a natural compound found in fruits and vegetables such as sweet corn, rice bran, and dong quai, is an encouraging drug known for its diverse positive effects on the body, including anti-inflammatory, anti-apoptotic, and neuroprotective properties. Our study aimed to investigate the potential antitumor effects of ferulic acid to inhibit tumor growth and inflammation of HCC in rats. HCC was induced in rats by administering thioacetamide. Additionally, some rats were given 50 mg/kg of ferulic acid three times a week for 16 weeks. Liver function was assessed by measuring serum alpha-fetoprotein (AFP) and examining hepatic tissue sections stained with hematoxylin/eosin or anti-hypoxia induced factor-1α (HIF-1α). The hepatic mRNA and protein levels of HIF-1α, nuclear factor κB (NFκB), tumor necrosis factor-α (TNF-α), mammalian target of rapamycin (mTOR), signal transducer and activator of transcription 3 (STAT3), cMyc, and cyclin D1 were examined. The results showed that ferulic acid increased the rats' survival rate by reducing serum AFP levels and suppressing hepatic nodules. Furthermore, ferulic acid ameliorated the appearance of vacuolated cytoplasm induced by HCC, reduced apoptotic nuclei, and necrotic nodules. Finally, ferulic acid decreased the expression of HIF-1α, NFκB, TNF-α, mTOR, STAT3, cMyc, and cyclin D1. In conclusion, ferulic acid is believed to possess antitumor properties by inhibiting HCC-induced hypoxia through the suppression of HIF-1α expression. Additionally, it helps in reducing the expression of mTOR, STAT3, cMyc, and cyclin D1, thereby slowing down tumor growth. Lastly, ferulic acid reduced hepatic tissue inflammation by downregulating NFκB and TNF-α.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"900-910"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141875052","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}

Since then, researchers have been investigating the efficacy and side effects of its medication, up until now. From the viewpoint of Persian medicine, some medications such as antihistamines may cause retention of secretions and lead to exacerbation and spread of the disease in the body. There are studies with conflicting results regarding the effectiveness of antihistamines in COVID-19. Systematic reviews found a lack of data on beneficial effect of antihistamine-decongestant-analgesic combinations for the common cold and a limited short-term effect of antihistamines on severity of overall symptoms. This prospective cohort study was designed to investigate the relationship between the use of antihistamines and the severity of COVID-19 symptoms. Three hundred patients with a diagnosis of COVID-19 participated in the study in Shiraz, Iran from December 4, 2021 until January 24, 2022. The interviews were conducted via phone call by a single interviewer. Patients were followed weekly for 4 weeks. We collected information by using a data collection form, containing demographic information, underlying disease, COVID-19 symptoms, treatment methods, medications, and a list of antihistamines and herbs that might have been used. Generalized estimating equations were applied to assess the relationship between the severity of COVID-19 and the use of antihistamines, taking into account potential confounding factors such as time and herbal consumption. The difference in the severity of COVID-19 disease in antihistamine users compared to nonusers was not significant in 4 weeks despite the higher baseline severity in nonusers. The comparison of two groups of antihistamine users and nonusers showed that there was a significant difference (p = 0.001) regarding the use of herbal medicines.","PeriodicalId":16112,"journal":{"name":"Journal of Investigative Medicine","volume":" ","pages":"857-862"},"PeriodicalIF":2.5,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141875016","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}
