Long‐term excess alcohol consumption leads to a domino effect of pathological outcomes and onset of chronic illness. However, the risks of alcohol consumption extend beyond long‐term health issues. Because habitual alcohol drinkers reach a state of systemic homeostasis, when they attempt withdrawal, they experience many negative physiological effects and may develop alcohol withdrawal syndrome. The complex interplay between alcohol consumption and withdrawal does not result solely in behavioral issues. Rather, a substantial number of important physiological adaptations and potential problems underly habitual drinking. Addressing these issues requires comprehensive medical observation and intervention. Here, we summarize the pathophysiological mechanisms, clinical diseases, and related treatment methods of alcohol consumption and withdrawal. The aim was to provide a reference to improve understanding of alcohol use and promote an informed approach to alcohol withdrawal.","PeriodicalId":502918,"journal":{"name":"Medicine Advances","volume":"126 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139175112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Dynamic serum testosterone concentration may predict in vitro fertilization yield during ovarian stimulation by a gonadotrophin‐releasing hormone agonist long protocol in women with normal ovarian reserve","authors":"Yang Zhao, X. Jiao, Jiawen Xu, Chu Chu, Yacong Cao, Huiyu Xu, Wenming Xu, Xiaomiao Zhao","doi":"10.1002/med4.41","DOIUrl":"https://doi.org/10.1002/med4.41","url":null,"abstract":"To determine whether dynamic changes in serum total testosterone (TT) levels during controlled ovarian stimulation (COS) by a GnRH‐a (gonadotrophin‐releasing hormone agonist) long protocol may predict pregnancy in women with normal ovarian reserve in in vitro fertilization.The TT measurements were added to routine hormone tests during COS. The TT dynamic changes, clinical pregnancy rate, and quality of oocytes and embryos of 109 patients were analyzed.Compared with the non‐pregnancy group, in the pregnancy group the TT level on Gn initial day (TTinitial‐d) increased sharply when the dominant follicle reached a diameter 10–12 mm [TTfΦ (10–12)‐d] and on human chorionic gonadotrophin (HCG) day (TTHCG‐d), also the ratios of TTfΦ (10–12)‐d to TTinitial‐d (1.23 ± 0.37 vs. 1.10 ± 0.58, p = 0.040) and TTHCG‐d to TTinitial‐d (2.32 ± 1.26 vs. 2.00 ± 1.43, p = 0.019) increased notably. Of the 2 TT ratios, the first tertile limit was regarded as the threshold of high TT ratios (1.00, 1.45). High tertiles had higher pregnancy rates than low tertiles (82.86% vs. 42.11%, p = 0.006; 71.43% vs. 44.83%, p = 0.040). The 2 TT ratios were positively associated with the number of metaphase II oocytes and good‐quality embryos.Of COS in a long GnRH‐a protocol with optimized outcome, serum TT kinetics appears to be characterized by sharp rises at the early and late stages of follicle growth. The ratios of TTΦ (10–12)‐d to TTinitial‐d and TTHCG‐d to TTinitial‐d may be predictors for pregnancy and qualitative outcomes of oocytes and embryos.","PeriodicalId":502918,"journal":{"name":"Medicine Advances","volume":"7 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139173572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proteomic studies helped generate molecular landscape for LUAD. However, the molecular basis of early lymph node metastases remains unknown in patients with LUAD.Surgically resected LUAD tissues and paired normal tissues were selected from 25 patients with stage pT1bN2M0 (group of metastases [GM]) and 27 patients with stage T2b‐3N0M0 (group of large primary focus, GL) who had not undergone any anti‐tumor treatment. 4D‐Label‐free proteomics sequencing was performed among these tissues. The clinicopathological information was retrieved from the electronic medical record system in Guangdong Provincial People's Hospital.Compared with GL tumor tissue, 89 upregulated and 155 downregulated proteins were identified in GM tumor tissue. Upregulated proteins of GM were enriched in the ECM‐receptor interaction and PI3K‐AKT pathway under Kyoto Encyclopedia of Genes and Genomes enrichment analysis. And then, the median disease‐free survival (DFS) of GM phenotype patients was used as the cut‐off value, and GM was divided into two groups with significantly different survival outcomes (DFS good vs. DFS Poor: DFS: p < 0.0001; overall survival: p = 0.0017). All members of the Microchromosome maintenance protein family were highly expressed in the DFS‐poor group, especially MCM2. Proteome‐based stratification of LUAD revealed three subtypes (S‐2, S‐2, and S‐3) related to different clinical and molecular features. S‐3 had higher catabolism‐related pathways enriched, such as amino sugar and nucleotide sugar metabolism and fructose and mannose metabolism, which has the worst prognosis (S1 vs. S2 vs. S3, RFS: p = 0.042).Proteomics analyses revealed that the activation of the extracellular matrix and intracellular signal transduction might be the driving mechanisms for early lymph node metastasis. Higher expressed cell proliferation related pathways of early lymph node metastatic LUAD may accelerate the recurrence after curative surgery. Three proteomic subgroups of LUAD with distinct molecular and clinical characteristics were identified, the one of which characterized by enrichment of catabolism‐related pathways displayed the worst survival data.","PeriodicalId":502918,"journal":{"name":"Medicine Advances","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139230327","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Then, Uniform Manifold Approximation and Projection is applied to perform dimensionality reduction in prescription embeddings. Subsequently, Hierarchical Density‐Based Spatial Clustering of Applications with Noise is used for clustering. Finally, class‐based term frequency–inverse document frequency is used to generate several main drug combinations from the clustered results.The highest frequency of drugs used included Buddleja officinalis, Bidens pilosa, Angelica sinensis, Eriocaulon buergerianum, and Raw Rehmannia glutinosa. The most frequent drug combinations were “Eriocaulon buergerianum, Raw Rehmannia glutinosa, Prunella vulgaris, Notopterygium incisum” “Lycii Fructus, Bidens pilosa, Buddleja officinalis” and “Kochiae Fructus, Cortex Dictamni.”The proposed data mining algorithm based on BERTopic demonstrated promising outcomes in the analysis of TCM prescription medication rules. This method exhibited simplicity and efficiency, thereby offering a novel avenue for analysis.","PeriodicalId":502918,"journal":{"name":"Medicine Advances","volume":"5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139233555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, engineered T cell immunotherapy targeting tumor‐associated antigens (TAAs) has had some success against virus‐associated cancer, although these treatments are associated with side effects. TAA‐specific‐modified T cells may kill cancer cells but they also react with and damage healthy tissue. During an oncogenic virus infection, viral DNA integrates into the host genome, leading to the expression of viral‐specific antigens in the tumor in a restricted and durable manner. The cross‐reactive side‐effects of conventional TAA‐specific engineered T cell treatment can be avoided by creating engineered T cells that target oncogenic viral antigens. To chart a course for the discovery of additional viral‐specific antigens and their combination with immune checkpoint inhibition therapies, this review summarizes the development, preclinical research, and clinical application of oncogenic viral antigen–specific T cell immunotherapy. This review also addresses challenges such as virus mutation and diverse integration, which can result in the loss of the target.","PeriodicalId":502918,"journal":{"name":"Medicine Advances","volume":"18 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139243559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
