The National Comprehensive Cancer Network (NCCN) released the latest version 1, 2022 of "NCCN guidelines for the clinical diagnosis and treatment of small cell lung cancer" (hereinafter referred to as "guideline"). Based on high-quality evidence-based medicine, this guideline provides references of clinical diagnosis and treatment for clinicians around the world. Compared with the version 3, 2021 of the "guideline", updates and revisions mainly focused on the progress of radiotherapy and systemic treatment. This article will interpret the updated therapy content in this new version of the "guideline".
Objective To study the anatomy and variations of hepatic veins draining into inferior vena cava （IVC）， and to classify the surgical techniques of piggyback liver transplantation （PBLT） based on the view of hepatic veins anatomy with IQQA liver image analysis system so as to provide the important basis for the perioperative clinical decision making. Methods Two hundred and forty-eight cases of PBLT were preformed in the Zhongnan Hospital of Wuhan University and the 3rd Xiangya Hospital of Central South University from May 2000 to August 2007， the types of hepatic veins were summarized according to the anatomy of hepatic veins and short hepatic veins draining into IVC at the second and third hepatic hilars. Forty cases of PBLT were preformed in the Zhongnan Hospital of Wuhan University from March 2010 to April 2013， and the anatomy of hepatic veins was reviewed with IQQA liver image analysis system. The anatomy of hepatic veins and technological type of liver transplantation were recorded respectively. Results Of these 248 livers studied in our center， type Ⅰ（the left and middle hepatic vein joined as one trunk ） was found in 142 cases （57.25%）， type Ⅱ （the right and middle hepatic vein joined as one trunk） was 54 cases （21.77%）， type Ⅲ （three hepatic veins joined as one trunk） in 14 cases （5.64%）， type Ⅳ （the left， middle， and right hepatic veins were all unique）in 34 cases （13.71%）， and type Ⅴ （no hepatic veins but short hepatic veins） in 4 cases （1.61%）. The data of 40 cases of PBLT from IQQA liver image analysis system showed that type Ⅰwere found in 24 cases （60.00%）， type Ⅱin 9 cases（22.50%）， type Ⅲ in 2 cases （5.00%）， type Ⅳ in 4 cases （10.00%）， and type Ⅴ in 1 case （2.50%）， which were matched with hepatic vein classification standard of the author. Conclusions Studying the anatomy and variations of hepatic veins draining into IVC with IQQA liver image analysis system and classifying the surgical techniques of PBLT （type Ⅰ，Ⅱ，Ⅲ，andⅣA patients can be performed classical PBLT；Type ⅣB and Ⅴ patients can only be performed ameliorative PBLT） could provide an important basis for clinical preoperative decision.
The World Health Organization (WHO) released the “Global report on hypertension” on September 19, 2023. This report systematically summarizes the prevalence, mortality, diagnosis and treatment of hypertension in various countries, and elucidates the current situation of hypertension management, and gives a series of suggestions on how to manage hypertension, providing new thinking and inspiration for countries to optimize hypertension management. Through the summary of relevant studies and reports, this paper further reviews the present situation, early identification and management of hypertension.
Cutaneous squamous cell carcinoma (cSCC) is the second most common human skin tumor. In recent years, the incidence of cSCC is increasing annually. Although most cSCC is curable after basic treatment, the advanced cSCC progresses rapidly and poses a significant risk for the impact on quality of life and death. In 2017, the latest version of cSCC management guideline was developed by the American Academy of Dermatology (AAD) based on extensive evidence-based medical evidence, including cSCC biopsy techniques, histopathological assessment, clinical staging and grading, surgical and nonsurgical treatment, follow-up, recurrence prevention, and management of the advanced cSCC. The purpose of this article is to briefly introduce and interpretate this guideline.
The subtype of lung cancer that presents as subsolid nodules on imaging exhibits unique biological behavior and favorable prognosis. Recently, the American Association for Thoracic Surgery (AATS) issued "The 2023 American Associationfor Thoracic Surgery (AATS) expert consensus document: Management of subsolid lung nodules". This consensus, based on the latest literature and current clinical experience, proposes updated strategies for managing subsolid nodules. It emphasizes the correlation between imaging findings and pathological classification, individualized follow-up and surgical management strategies for subsolid nodules, and multimodal treatment approaches for multiple subsolid pulmonary nodules.
Choroideremia (CHM) is a rare inherited eye disease that leads to blindness. It is caused by pathogenic variants in the CHM gene and exhibits X-linked recessive inheritance. Affected males present with progressively worsening night blindness, visual field loss, and decreased central vision, which can cause blindness in middle age. Although female carriers typically exhibit mild symptoms, it is essential to understand their clinical features for early diagnosis of patients as well as genetic counseling of family members. Currently, the recognition and diagnosis rates of CHM among ophthalmologists in various regions and levels of hospitals in China still need to be improved. A standardized clinical pathway is needed to meet the diagnostic and treatment needs of patients. Led by the the Chinese Hereditary Ocular Disease Diagnosis and the Treatment Group and the Chinese Hereditary Ocular Disease Alliance, based on existing evidence both domestically and internationally, the Expert consensus on diagnosis and treatment of choroideremia (2024) has been compiled, systematically and comprehensively elaborating on the standardized clinical pathways for CHM. Interpreting the key points of this consensus will help highlight its core points and ideas, enhancing the standardization and effectiveness of the diagnosis and treatment of CHM by ophthalmologists from all levels of hospitals.
Dose-response meta-analysis (DRMA) is one of the branches of meta-analysis, which has provided important evidence for clinical research. Since introducing into China, it has gained great attention. In order to improve the reporting quality of DRMA, Dr. Chang Xu et al. developed the reporting guideline for DAMA——G-Dose Checklist. It was published in Chinese Jouranl of Evidence-based Medicine in 2016. This paper interprets the checklists so as to promote the understanding and use of it.
In July 2023, six scientific organizations, including the American Heart Association (AHA) and the American College of Cardiology (ACC), jointly released the 2023 AHA/ACC/ACCP/ASPC/NLA/PCNA guideline for the management of patients with chronic coronary disease. By reviewing the latest scientific data, the guideline reemphasized the importance of a healthy diet, regular physical activity and smoking cessation in cardiovascular health. Routine testing is limited to patients with changes in clinical or functional status. Regarding the clinical management of CCD, the guideline limited the use of beta-blockers (BB) and updated recommendations for the usage of three drugs, including sodium-glucose cotransporter-2 inhibitors (SGLT2i), glucagon-like peptide-1 (GLP-1) receptor agonists, and bempedoic acid.
Pathological diagnosis is the gold standard for confirming breast cancer. Traditional manual pathological diagnosis methods for breast cancer are time-consuming, labor-intensive, highly subjective, and exhibit poor diagnostic consistency. In recent years, artificial intelligence (AI) technology has rapidly advanced and is progressively being applied clinically as a promising early diagnostic tool. However, many existing AI models lack interpretability, which limits the trustworthiness of their clinical application. Khater et al, by combining a high-precision machine learning model with an explainable AI model, achieved highly accurate breast tumor diagnosis and provided explanations for key biological and pathological features influencing the diagnostic results. This points the way for the future application and development of AI in medical diagnosis and treatment. The article interprets the main content of that study, and analyzes the advantages and limitations of AI in medical diagnosis and treatment, with the aim of promoting its better application in clinical practice.
