Update of the clinical guideline for hypertension diagnosis and treatment in Iran

BackgroundThis article introduces the updated version of the Iranian guideline for the diagnosis and treatment of hypertension in adults. The initial version of the national guideline was developed in 2011 and updated in 2014. Among the reasons necessitating the update of this guideline were the passage of time, the incompleteness of the scopes, the limitation of the target group, and more important is the request of the ministry of health in Iran.MethodThe members of the guideline updating group, after reviewing the original version and the new evidence, prepared 10 clinical questions regarding hypertension, and based on the evidence found from the latest scientific documents, provided recommendations or suggestions to answer these questions.ResultAccording to the updated guideline, the threshold for office prehypertension diagnosis should be considered the systolic blood pressure (SBP) of 130-139 mmHg and/or the diastolic blood pressure (DBP) of 80-89 mmHg, and in adults under 75 years of age without comorbidities, the threshold for office hypertension diagnosis should be SBP ≥ 140 mmHg and or DBP ≥ 90 mmHg.The goal of treatment in adults who lack comorbidities and risk factors is SBP < 140 mmHg and DBP < 90 mmHg. The first-line treatment recommended in people with prehypertension is lifestyle modification, while for those with hypertension, pharmacotherapy along with lifestyle modification. The threshold to start drug therapy is determined at SBP ≥ 140 mmHg and or DBP ≥ 90 mmHg, and the first-line treatment is considered a drug or a combined pill of antihypertensive drugs, including ACEIs, ARBs, thiazide and thiazide-like agents, or CCBs.At the beginning of the pharmacotherapy, the Guideline Updating Group members suggested studying serum electrolytes, creatinine, lipid profile, fasting sugar, urinalysis, and an electrocardiogram. Regarding the visit intervals, monthly visits are suggested at the beginning of the treatment or in case of any change in the type or dosage of the drug until achieving the treatment goal, followed by every 3-to-6-month visits. Moreover, to reduce further complications, it was suggested that healthcare unit employees use telehealth strategies.ConclusionsIn this guideline, specific recommendations and suggestions have been presented for adults and subgroups like older people or those with cardiovascular disease, diabetes mellitus, chronic kidney disease, and COVID-19.

Abstract PO4-20-09: Successful outcome of locally advanced HR+HER2+ breast cancer treatment in a young female after pancreas-kidney transplantation. 3-year follow-up

Abstract Background Solid organs recipients with subsequent cancer comprise a group of patients with unmet medical needs: they lack any clinical trials or guidelines for treatment. There are only individual case reports in literature. Meanwhile their number is growing due to achievements in transplantology and improved cancer diagnosis. Case presentation А young 34-year-old female attended our center in September 2019 with a palpable mass and peau d'orange of the left breast. A core-needle biopsy of the left breast mass revealed invasive ductal carcinoma G3, estrogen receptor 7 (Allred), progesterone receptor 6 (Allred), HER-2 (3+), Ki-67 49%. Left axillary lymph node biopsy revealed metastatic breast cancer. After a complete examination the clinical stage was cT4bN1fM0, IIIB stage. The patient had a history of Type 1 diabetes mellitus since 2003 leading to multiple complications including terminal diabetic nephropathy, which required renal replacement therapy with the use of long-term hemodialysis since July 2014. The other complications consisted of severe retinopathy with corneal transplantation on the left eye in April 2013, an episode of right eye hemophthalmia in March 2016 with consequent loss of vision in the right eye, polyneuropathy, gastropathy and enteropathy. The patient underwent a simultaneous pancreas-kidney transplantation in April, 2016 and was on permanent immunosuppressive therapy with tacrolimus 8 mg daily and methylprednisolone 8 mg daily. The function of both transplants was satisfactory. This unique case was published by Pinchuk A. et al. in Transplant Proceedings, 2017 [doi: 10.1016/j.transproceed.2017.10.005]. A multidisciplinary approach was applied to tailoring treatment plan for this patient. Initially immunosuppressive therapy was modified: the patient discontinued methylprednisolone and started everolimus with simultaneous tacrolimus dose reduction (their doses adjusted according to blood concentrations). The tumor board decision was to start neoadjuvant therapy with regimen with the mildest and the most manageable toxicity profile and to avoid anthracyclines. From October to December 2019 the patient received 12 cycles of paclitaxel 80 mg/m2 day 1 weekly and 4 cycles of anti-HER2 dual blockade: trastuzumab 8 mg/kg day 1 followed by 6 mg/kg day 1 every 21 days + pertuzumab 840 mg day 1 followed by 420 mg day 1 every 21 days. Adverse events were: stomatitis grade 1, palmar-plantar erythrodysesthesia grade 1, diarrhea grade 2. Partial response was evaluated in the end of December 2019, but due to persistent skin edema, she was not a candidate for surgical treatment. The tumor board decision was to proceed with T-DM1 + pertuzumab based on the results of the KRISTINE trial [doi:10.1016/s1470-2045(17)30716-7]. From January to March 2020 the patient received 4 cycles of trastuzumab-emtansine 3,6 mg/kg day 1 every 21 days + pertuzumab 420 mg day 1 every 21 days. The patient tolerated this treatment with mild toxicity: ALT &amp; AST increase grade 2 and diarrhea grade 2. Considering that the edema was significantly reduced, surgical treatment was planned. The patient underwent a modified radical mastectomy for left breast cancer on 14 of April 2020. The pathological stage was ypT1аN0 R0, RCB I. The patient continued trastuzumab emtansine until November 2020 (up to 1 year of anti-HER2 targeted therapy) in the adjuvant setting. In June 2020 she underwent locoregional radiation therapy. Tamoxifen with ovarian function suppression (LHRH agonists) for 5 years was started in June 2020. Fortunately, after 3 years of follow-up after surgery there is no evidence of disease and no delayed cancer treatment complications. Conclusion: Personalized multidisciplinary team decisions for cancer patients after organ transplantation are crucial to further improve the long-term outcome of these patients.

Clinical practice guidelines for diagnostic and treatment of the chronic heart failure.

Chronic heart failure continues to be one of the main causes of impairment in the functioning and quality of life of people who suffer from it, as well as one of the main causes of mortality in our country and around the world. Mexico has a high prevalence of risk factors for developing heart failure, such as high blood pressure, diabetes, and obesity, which makes it essential to have an evidence-based document that provides recommendations to health professionals involved in the diagnosis and treatment of these patients. This document establishes the clinical practice guide (CPG) prepared at the initiative of the Mexican Society of Cardiology (SMC) in collaboration with the Iberic American Agency for the Development and Evaluation of Health Technologies, with the purpose of establishing recommendations based on the best available evidence and agreed upon by an interdisciplinary group of experts. This document complies with international quality standards, such as those described by the US Institute of Medicine (IOM), the National Institute of Clinical Excellence (NICE), the Intercollegiate Network for Scottish Guideline Development (SIGN) and the Guidelines International Network (G-I-N). The Guideline Development Group was integrated in a multi-collaborative and interdisciplinary manner with the support of methodologists with experience in systematic literature reviews and the development of CPG. A modified Delphi panel methodology was developed and conducted to achieve an adequate level of consensus in each of the recommendations contained in this CPG. We hope that this document contributes to better clinical decision making and becomes a reference point for clinicians who manage patients with chronic heart failure in all their clinical stages and in this way, we improve the quality of clinical care, improve their quality of life and reducing its complications.

The Japanese breast cancer society clinical practice guidelines for radiation treatment of breast cancer, 2022 edition.

The Breast Cancer Clinical Practice Guidelines, organized by the Japanese Breast Cancer Society (JBCS), were published in 2022. We present the English version of the Radiation Therapy (RT) section of the guidelines. The JBCS formed a task force to update the 2018 version of the JBCS Clinical Practice Guidelines. The Background Questions (BQs) contain the standard treatments for breast cancer in clinical practice, whereas the Clinical Questions (CQs) address daily clinical questions that remain controversial. Future Research Questions (FRQs) explore the subjects that are considered important issues, despite there being insufficient data for inclusion as CQs. The task force selected the 12 BQs, 8 CQs, and 6 FRQs for the RT section. For each CQ, systematic literature reviews and meta-analyses were conducted according to the Minds Manual for Guideline Development 2020, version 3.0. The recommendations, strength of recommendation, and strength of evidence for each CQ were determined based on systematic reviews and meta-analyses, and finalized by voting at the recommendation decision meeting.

Clinical guidelines for prevention, diagnostics, treatment and recovery from acute radiation injuries: classification and basic pathology

The provision of state guarantees to citizens with medical care is achieved by compliance with clinical recommendations by medical organizations. However, acute diseases (conditions) caused by excess radiation were excluded from the relevant pathologies for the development of appropriate clinical recommendations. The current events increase the relevance of acute radiation pathology for the healthcare system and determine the high risk of such cases among the personnel of radiation-hazardous facilities and population. The necessity of developing national clinical guidelines for the prevention, diagnosis, treatment, and rehabilitation of acute radiation injury victims is substantiated. Based on an analytical review of the databases of NEB, PubMed, and Medline for 1970 to 2023 on the problem of prevention, diagnosis, treatment, and rehabilitation of individuals exposed to excess radiation and analysis of the regulatory framework governing the process of creating clinical recommendations in the Russian Federation on the provision of medical care to victims of acute radiation injuries, the main terms and their definitions relevant to acute radiation pathology were formulated, which must be unified when developing clinical recommendations. The basic classification of acute radiation lesions is presented, systematizing the variety of possible clinical forms of diseases (conditions) and their etiopathogenetic variants based on the characteristics of the types of ionizing radiation sources and individual characteristics of the conditions of acute radiation exposure. Variants of working clinical classifications of acute radiation lesions based on the generalization of the experience in the country and the world on the systematization of acute radiation pathology were determined. In general, the expediency of developing a group of clinical recommendations for the prevention, diagnosis, treatment, and rehabilitation of acute radiation injuries, covering all the various current clinical forms of diseases caused by excess (uncontrolled, unregulated, emergency) exposure, is justified. The task of determining the current list of diseases (conditions) and groups of diseases (conditions) caused by excessive human exposure in the dose range that can lead to the development of acute radiation lesions is of practical importance both for departmental medicine and the country’s healthcare system.

Clinical guidelines for prevention and treatment of CAT in Japan and other countries.

Cancer-associated thrombosis (CAT) is an important prognostic factor for an increasing number of cancer patients. Understanding of CAT among cancer care providers has grown in recent years, and guidelines for the prevention and treatment of CAT have been published in Japan and around the world. In this article, we introduce these major guidelines and discuss differences we identified between the Japanese guidelines and those of other countries, with a focus on problems and issues. Insurance coverage of low-molecular-weight heparin and indications for primary prevention with direct oral anticoagulants in particular require urgent consideration.

Clinical practice guidelines for prevention and treatment of postoperative gastrointestinal disorder with Integrated Traditional Chinese and Western Medicine (2023).

Postoperative gastrointestinal disorder (POGD) was a common complication after surgery under anesthesia. Strategies in combination with Traditional Chinese Medicine and Western medicine showed some distinct effects but standardized clinical practice guidelines were not available. Thus, a multidisciplinary expert team from various professional bodies including the Perioperative and Anesthesia Professional Committees of the Chinese Association of Integrative Medicine (CAIM), jointly with Gansu Province Clinical Research Center of Integrative Anesthesiology/Anesthesia and Pain Medical Center of Gansu Provincial Hospital of Traditional Chinese Medicine and WHO Collaborating Center for Guideline Implementation and Knowledge Translation/Chinese Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Center/Gansu Provincial Center for Medical Guideline Industry Technology/Evidence-based Medicine Center of Lanzhou University, was established to develop evidence-based guidelines. Clinical questions (7 background and 12 clinical questions) were identified through literature reviews and expert consensus meetings. Based on systematic reviews/meta-analyses, evidence quality was analyzed and the advantages and disadvantages of interventional measures were weighed with input from patients' preferences. Finally, 20 recommendations were developed through the Delphi-based consensus meetings. These recommendations included disease definitions, etiologies, pathogenesis, syndrome differentiation, diagnosis, and perioperative prevention and treatment.

Label‐Free Virtual Peritoneal Lavage Cytology via Deep‐Learning‐Assisted Single‐Color Stimulated Raman Scattering Microscopy

Clinical guidelines for gastric cancer treatment recommend intraoperative peritoneal lavage cytology to detect free cancer cells. Patients with positive cytology require neoadjuvant chemotherapy instead of instant resection, and conversion to negative cytology results in improved survival. However, pathologists’ or artificial intelligence's accuracy of cytological diagnosis is disturbed by manually produced, unstandardized slides. In addition, the elaborate infrastructure makes cytology accessible to a limited number of medical institutes. This work develops CellGAN, a deep learning method that enables label‐free virtual peritoneal lavage cytology by producing virtual hematoxylin–eosin‐stained images with single‐color stimulated Raman scattering microscopy. A structural similarity loss is introduced to overcome the challenge of unsupervised virtual pathology techniques that cannot accurately present cellular structures. This method achieves a structural similarity of 0.820 ± 0.041 and a nucleus area consistency of 0.698 ± 0.102, indicating the staining fidelity outperforms the state‐of‐the‐art method. Diagnosis using virtually stained cells reaches 93.8% accuracy and substantial consistency with conventional staining. Single‐cell detection and classification on virtual slides achieve a mean average precision of 0.924 and an area under the receiver operating characteristic curve of 0.906, respectively. Collectively, this method achieves standardized and accurate virtual peritoneal lavage cytology and holds great potential for clinical translation.

Contemporary Diagnostic Reporting for Prostatic Adenocarcinoma: Morphologic Aspects, Molecular Correlates, and Management Perspectives.

The diagnosis and reporting of prostatic adenocarcinoma have evolved from the classic framework promulgated by Dr Donald Gleason in the 1960s into a complex and nuanced system of grading and reporting that nonetheless retains the essence of his remarkable observations. The criteria for the "Gleason patterns" originally proposed have been continually refined by consensuses in the field, and Gleason scores have been stratified into a patient-friendly set of prognostically validated and widely adopted Grade Groups. One product of this successful grading approach has been the opportunity for pathologists to report diagnoses that signal carefully personalized management, placing the surgical pathologist's interpretation at the center of patient care. At one end of the continuum of disease aggressiveness, personalized diagnostic care means to sub-stratify patients with more indolent disease for active surveillance, while at the other end of the continuum, reporting histologic markers signaling aggression allows sub-stratification of clinically significant disease. Whether contemporary reporting parameters represent deeper nuances of more established ones (eg, new criteria and/or quantitation of Gleason patterns 4 and 5) or represent additional features reported alongside grade (intraductal carcinoma, cribriform patterns of carcinoma), assessment and grading have become more complex and demanding. Herein, we explore these newer reporting parameters, highlighting the state of knowledge regarding morphologic, molecular, and management aspects. Emphasis is made on the increasing value and stakes of histopathologists' interpretations and reporting into current clinical risk stratification and treatment guidelines.

Guidelines for clinical diagnosis and treatment of advanced triple negative breast cancer in China（2024 edition）

Breast cancer ranks as the most common female malignancy worldwide. Data from GLOBOCAN 2020 showed that breast cancer surpassed lung cancer and become the leading malignancy globally which was a serious threat to women's health. Different from Caucasian, there is a lower prevalence of breast cancer in Chinese women. But the age-standardized incidence rate of breast cancer in China has reached to 39.1 per 100,000 in 2020, with 416,000 new cases, accounting for 18.4% of global breast cancer burden, due to multiple factors such as lifestyle and dietary habits changes in recent years[1]. The treatment and prevention of breast cancer are becoming increasingly a tuff task. In addition, triple-negative breast cancer (TNBC) is a subtype with higher malignancy and worse prognosis. Due to lack of specific therapeutic targets, less treatment progress has been made in recent years. There is even less progress in the therapy of advanced TNBC, but huge unmet needs exist for further therapeutic optimization. Echoing advocacy from The Society of Breast Cancer China Anti-Cancer Association; International Medical Exchange Society, Chinese Anti-Cancer Association; Breast Cancer Group, Branch of Oncologist, Chinese Medical Doctor Association, top experts from multidisciplinary departments of breast cancer in China have consensus on this "Guidelines for Clinical Diagnosis and Treatment of Advanced Triple-Negative Breast Cancer in China (2024 Edition)" according to the latest evidence based updates. We hope this pater can guide or optimize the precise therapeutic decision-making for advanced triple-negative breast cancer in China.

Fosfomycin susceptibility testing and resistance mechanisms in Enterobacterales in South Africa.

Fosfomycin treatment of urinary tract infections is increasingly attractive due to escalating antibiotic resistance rates among urinary pathogens. Standard antibiotic susceptibility testing methods perform poorly for fosfomycin as there is poor correlation between susceptibility results and clinical outcomes in urinary pathogens other than Escherichia coli. We evaluated the performance of fosfomycin susceptibility testing in E. coli and Klebsiella pneumoniae to determine whether fosfomycin susceptibility is associated with molecular resistance mechanisms. Forty-six each of E. coli and K. pneumoniae clinical isolates were obtained from a tertiary hospital in South Africa, from 01 June 2017 to 31 January 2018. Agar dilution, disk diffusion, and gradient diffusion were performed and interpreted using the Clinical Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing guidelines. Molecular resistance mechanisms were identified by whole genome sequence analysis. Disk diffusion and gradient diffusion were accurate alternatives for fosfomycin susceptibility testing in E. coli (98% categorical agreement), but not in K. pneumoniae (47% categorical agreement). All E. coli isolates contained at least one resistance mechanism, but only one isolate with a fosA gene was resistant. In K. pneumoniae, 63% (29/46) and 70% (32/46) of isolates were susceptible to fosfomycin, using Clinical Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing breakpoints, respectively, despite all isolates containing a fosA gene and a uhpT mutation. A better understanding of fosfomycin susceptibility and improved antibiotic susceptibility testing tools could improve diagnostic capability and clinical guidelines for fosfomycin treatment of urinary tract infections. This study highlights the importance of adhering to interpretive guidelines when performing antimicrobial susceptibility testing and the need for simplified, accurate and standardised susceptibility testing methodology and interpretation for fosfomycin in Enterobacterales organisms.

Strategies to improve delivery of equitable and evidence-informed care for pregnant and birthing people with a substance use disorder in acute care settings: A scoping review protocol.

This protocol outlines a proposed scoping review to characterize evidence on implementation and quality improvement (QI) strategies that aim to improve equitable, evidence-informed care delivery for pregnant and birthing people with substance use disorder (SUD) in acute care. Untreated SUD during pregnancy is associated with an increased risk of overdose and severe maternal morbidity. Acute care settings are one important place to deliver equitable, evidence-informed clinical care. While clinical practice guidelines for substance use treatment and care of pregnant and birthing people with SUD exist, there are gaps in implementation. Our population of interest is pregnant and birthing people with SUD in an acute care setting. We will include US-based studies that describe or evaluate implementation or QI strategies, including experimental, observational, and descriptive studies published from 2016 to 2023. The proposed scoping review will be conducted in accordance with JBI methodology for scoping reviews and registered at OSF (registration number: BC4VZ). We will search MEDLINE (PubMed), CINAHL Complete (EBSCO), Scopus (Elsevier), and APA PsychInfo (Ovid) for published studies. Conference proceedings and Perinatal Quality Collaborative websites will be searched for grey literature. Two reviewers will independently screen then extract studies that meet inclusion criteria using a data extraction tool. The completion of this scoping review will help illuminate strengths and gaps in research and practice that aim to inform substance use treatment and care in acute care settings for pregnant and birthing people with SUD.

Risk Factors and Clinical Characterization of Cardiovascularand Cerebrovascular Events in Elderly Hemodialysis Patients.

The purpose of this study was to assess the risk factors and clinical characteristics of cardiovascular and cerebrovascular events in elderly hemodialysis patients. Elderly patients undergoing hemodialysis (HD) at Deqing County People's Hospital in Zhejiang, China, from May 2020 to May 2023 were enrolled in this study. They were divided into two groups depending on the occurrence of cardiovascular or cerebrovascular events: the case group and the control group. A total of 106 patients were enrolled in this study. Among them, 49 patients experienced cardiovascular or cerebrovascular events, resulting in an incidence rate of 46.23%. According to whether cardiovascular or cerebrovascular events occurred, 57 patients were assigned to the control group, and 49 patients were assigned to the case group. Comparing the basic information and clinical indicators of the two groups, significant differences were observed in patients with hypertensive nephropathy and diabetic nephropathy (P < .05). There were also significant differences in dialysis duration, smoking history, systolic and diastolic blood pressures, uric acid, blood glucose, total cholesterol (TC), lowdensity lipoprotein cholesterol (TG), C-reactive protein (CRP), and PTH (parathyroid hormone) levels and platelet-to-lymphocyte ratio (PLR), between the two groups (P < .05). Multivariate logistic regression analysis revealed that longer dialysis duration, higher systolic and diastolic blood pressures, elevated uric acid, TC, TG, LDL-C, PTH, and blood glucose levels, smoking history, elevated PLR, and CRP were independent risk factors for cardiovascular and cerebrovascular events. The ROC curve showed that these risk factors predicted cardiovascular and cerebrovascular events in patients. Patients with underlying diseases such as hypertensive or diabetic nephropathy are more likely to experience cardiovascular and cerebrovascular events. Longer dialysis duration, higher systolic and diastolic blood pressures, elevated uric acid, TC, TG, LDL-C, PTH and blood glucose levels, and boosted inflammatory reaction are risk factors for these events among elderly HD patients. The purpose of this study is to provide practical guidelines for clinical treatment. Comprehensive measures such as active intervention of risk factors, rational drug use and regular examination should be taken to improve the overall health level to the greatest extent for elderly patients with high-risk HD.

Construction and validation of a colon cancer prognostic model based on tumor mutation burden-related genes

Currently, immunotherapy has entered the clinical diagnosis and treatment guidelines for colon cancer, but existing immunotherapy markers cannot predict the effectiveness of immunotherapy well. This study utilized the TCGA-COAD queue to perform differential gene analysis on high and low-mutation burden samples, and screen differentially expressed genes (DEGs). To explore new molecular markers or predictive models of immunotherapy by using DEGs for NMF classification and prognostic model construction. Through systematic bioinformatics analysis, the TCGA-COAD cohort was successfully divided into high mutation burden subtypes and low mutation burden subtypes by NMF typing using DEGs. The proportion of MSI-H between high mutation burden subtypes was significantly higher than that of low mutation burden subtypes, but there was no significant difference in immunotherapy efficacy between the two subtypes. Drug sensitivity analysis showed significant differences in drug sensitivity between the two subtypes. Subsequently, we constructed a prognostic model using DEGs, which can effectively predict patient survival and immunotherapy outcomes. The prognosis and immunotherapy outcomes of the low-risk group were significantly better than those of the high-risk group. The external dataset validation of the constructed prognostic model using the GSE39582 dataset from the GEO database yielded consistent results. At the same time, we also analyzed the TMB and MSI situation between the high and low-risk groups, and the results showed that there was no significant difference in TMB between the high and low-risk groups, but the proportion of MSI-H in the high-risk group was significantly higher than that in the low-risk group. Finally, we conclude that TMB is not a suitable molecular marker for predicting the efficacy of immunotherapy in colon cancer. The newly constructed prognostic model can effectively differentiate the prognosis of colon cancer patients and predict their immunotherapy efficacy.

Analysis of factors influencing doctors' awareness of clinical guidelines for heart failure treatment

Aim. To find out the relationship between the awareness level of clinical guidelines on heart failure (HF) with reduced ejection fraction and a number of professional characteristics (specialty, work experience, self-assessment of awareness level, attitude towards the use of guidelines, the main way of document study). To improve the efficiency and development of the postgraduate education system, the factors that influence doctors' awareness of guidelines should be determined.Material and methods. The study included the results of an anonymous survey of 207 doctors (155 cardiologists, 44 therapists, 8 doctors of other specialties). To assess the significance of differences, Student's t-test, c2-test and Fisher's exact test were used.Results. The mean number of correct answers to the questionnaire among cardiologists was significantly higher than among general practitioners (p&lt;0,001). In the group of physicians with less than 5 years of work experience, there was a large variability in the mean number of correct answers — 6,2±4,0. Physicians with 6-10 years and 11-20 years of experience in their specialty were more likely to choose the correct answers than doctors with more than 20 years of experience. Professionals who considered themselves "fully informed" on clinical guidelines gave fewer correct answers than doctors who had less high self-rating (p&lt;0,001). The proportion of correct answers in the subgroup of doctors who consider guidelines to be mandatory was greater than in the subgroups of doctors who hold a different opinion (p&lt;0,05). The best results were shown by physicians who indicated direct text-oriented way as preferred for studying guidelines (p&lt;0,001).Conclusion. The awareness level of clinical guidelines on the treatment of HF by cardiologists should be considered insufficient, and by therapists — extremely low. Doctors are not sufficiently informed about the need to comply with clinical guidelines. When planning training, the specialty and work experience of the doctor should be taken into account. Unjustifiably high self-rating of knowledge interferes with professional development. The best way of self-education should be considered direct study of the text of clinical guidelines.

Clinical guidelines for diagnosis and treatment of cervical spondylotic myelopathy with the integrated traditional Chinese and Western medicine(2023)

The "Clinical Guidelines for Diagnosis and Treatment of Cervical Spondylotic Myelopathy with the Integrated Traditional Chinese and Western Medicine" were formulated by the Orthopedic and Traumatology Professional Committee of the Chinese Association of Integrative Medicine in accordance with the principles of evidence-based medicine and expert consensus, and provide clinicians with academic guidance on clinical diagnosis and treatment of CSM. The main content includes diagnostic points, disease grading assessment, TCM syndrome differentiation, surgical indications and timing, integrated traditional Chinese and Western medicine treatment, and postoperative rehabilitation. This guideline proposes for the first time that the treatment of CSM should follow the principle of grading, clarify the timing and methods of surgical treatment, establish common TCM syndrome differentiation and classification, attach importance to postoperative integrated rehabilitation of Chinese and Western medicine, and strengthen daily follow-up management. It hopes to promote the standardization, effectiveness, and safety of clinical treatment of CSM.

Subchorionic hematoma: Research status and pathogenesis (Review).

Subchorionic hematoma (SCH) is a hematoma in which blood accumulates between the chorion and decidua basalis due to the separation of the chorion and decidua basalis. It is common in patients with threatened abortion in early pregnancy and is mainly detected by ultrasound. SCH mainly manifests as an hypoechoic or anechoic crescent-shaped fluid dark area on ultrasound images. Although there are numerous studies on SCH, its pathogenesis and etiology remain unclear, and its influence on pregnancy outcomes is also controversial; there are also no uniform clinical treatment guidelines. Current studies suggest that the occurrence of SCH may be related to several factors, such as abnormal coagulation function, autoimmune factors of pregnant women, assisted reproduction, drug use during pregnancy and reproductive tract infection; however, its exact etiology remains unclear. Some studies suggest that SCH is associated with adverse pregnancy outcomes such as miscarriage, preterm birth, preeclampsia and fetal growth restriction, although other studies have found that SCH does not increase the risk of adverse pregnancy outcomes. Therefore, the present review mainly discusses the pathogenesis, etiology and treatment of SCH in an aim to provide a reference for the clinical treatment of this condition in pregnant women.
