СПЕКТР КЛИНИЧЕСКИХ ПРОЯВЛЕНИЙ Х-СЦЕПЛЕННОГО СИНДРОМА АЛЬПОРТА У ДЕВОЧЕК: ОДНОЦЕНТРОЕ КОГОРТНОЕ ИССЛЕДОВАНИЕ

X-linked Alport syndrome (XLAS) is an inherited disorder caused by genetic variants in gene COL4A5. The frequency and the severity of clinical manifestations as well as the risk of glomerulopathy progression are variable in XLAS in females, and the disease course features have not been sufficiently studied as yet. Since patient management tactics is determined by the disease course nature, studying the spectrum of XLAS clinical manifestations and prognosis in girls remains relevant. The purpose of this research was to determine the spectrum and the features of clinical manifestations of XLAS in girls. Materials and methods used: a single-center cohort prospective study was carried out by the Authors that included 74 girls aged 2 to 17 y/o with genetically proven XLAS diagnosis. Authors have analyzed the patients’ medical records identifying sensorineural hearing loss (SNHL), arterial hypertension (AH; blood pressure (BP) over 95% than at the patient’s age/height), albuminuria (Alb; norm<30 mg/mmol of creatinine), proteinuria (Pr; norm<100 mg/sq m/day) - with its degree, decrease in estimated glomerular filtration rate (eGFR, ml/min/1.73 sq m; norm≥90 ml/min/1.73 sq m) and angiotensin-converting enzyme inhibitors (ACEIs) therapy data. Results: all patients had hematuria with episodical macrohematuria in 27% of cases, proteinuria in 40%, eGFR decrease in 15%, SNHL in 8% and peripheral retinopathy in 7%. Girls with missense v. those with non-missense variants of COL4A5 more often had macrohematuria (0.15 v. 0.05; p=0.015) and albuminuria (1 v. 0.5; p<0.001) whilst no statistically significant difference was showed in proteinuria frequency and age of onset (0.48 v. 0.5 and 6.5 [3; 11] v. 5 [5; 8] y/o), eGFR decrease (0.15 v. 0.15; 12.4±2.6 v. 13.2 ±2.8 y/o), SNHL (0.07 v. 0.1; 13±2.8 v. 14.4±3.1 y/o) and retinopathy (0.04 v. 0.15; 14.3±3.5 v. 12.6±2.9 y/o). ACEIs therapy did not show any statistically significant effect on the cumulative proportion of patients with both proteinuria and eGFR decrease (log-rank test=1.25, p=0.213 and log-rank test=0.66, p=0.512, respectively). Conclusion: the results obtained demonstrate the need for a dynamic follow-up of girls with XLAS with the purpose of earliest possible detection of proteinuria and timely prescribing with nephroprotective therapy as well as hearing loss diagnosing and timely audiological correction.

Генетически-фенотипический профиль детей с атипичным гемолитико-уремическим синдромом

Atypical hemolytic uremic syndrome (aHUS) is a life-threatening disease caused by dysregulation of the alternative complement pathway as a result of mutations in complement genes or the formation of antibodies (AB) to some of the complement factors. Identification of the gene mutations incidence and the corresponding phenotypic features in pediatric patients with aHUS in Russia is aimed at improving the diagnosis and prognosis of the disease as well as treatment tactics planning for patient management. The purpose of this research was to determine the patterns of progression, prognosis and outcomes of aHUS in children depending on their genetic profile. Materials and methods used: the Article represents data from a retro- and prospective analyses of the characteristics of the course of aHUS in 172 children depending on their genetic profile performed in Jan. 2012-Feb. 2022. The sporadic form of aHUS was diagnosed after exclusion of the other forms of thrombotic microangiopathy (TMA), the familial form (in cases with the familial records), the acquired (CFH-Ab HUS) in cases with AB increase to factor H. AutoAb against factor H was determined by enzyme-linked immunosorbent assay (ELISA-VIDITEST anti-complement factor H). The search for mutations (n=167) was carried out using Next-generation Sequencing (NGS) and Sanger sequencing methods. Results: the sporadic form of aHUS was diagnosed in 96.9% of cases, familial in 3.1% and CFH-Ab HUS in 23.8%. The genetic nature of aHUS was confirmed in 53.4% of cases. Pathogenic mutations were detected in 8.6% of cases, probably pathogenic in 42.8% and those with unclear clinical significance in 46.8%. The complement genes mutations were detected in 88.5% of cases and mutations of genes not related to the complement system (ADAMTS13, DGKE, INF2) in 11.5%. The most frequently identified mutations were in the CFH (17.1%), C3 (12.9%) and CD46 (12.9%) genes and less frequently in CFI (7.1%), THBD (5.7%), CFHR5 (5.7%) and CFB (1.4%). In children with CFH-Ab HUS, the CFHR1/CFHR3 deletion was detected in 87.8% of cases, including in 19.4% in combination with mutations of unknown clinical significance. Multiple organ failure syndrome had developed in 77.8% of cases in children with pathogenic/probably pathogenic mutations, in 85.3% in patients with mutations of unknown clinical significance, in 91.8% in patients without mutations and in 83.3% in patients with CFHR1/CFHR3 deletion. Chronic kidney disease (CKD) stages 3 to 5 in sporadic/familial aHUS, regardless of genetic profile, had counted for 14.5% and 16.7% in CFH-Ab HUS. Lethal outcome occurred in 4.3% of cases in the presence of mutations, in 4.9% in the absence of mutations and in 2.8% in cases of CFHR1/CFHR3 deletion. Relapses of aHUS prior to the Eculizumab treatment had developed more often in the presence of CFHR1/CFHR3 mutations and deletion in comparison with children without mutations (31.4% v. 13.1%, p=0.0313 and 44.4% v. 13.1%, p= 0.004). Relapse of aHUS after discontinuation of the Eculizumab therapy had developed in 16.4% of cases. Risk factors for the relapse of aHUS were as follows: patient’s age above 12 months old at the time of the development of aHUS, severe arterial hypertension in the acute period, the use of Eculizumab at the fourth week after the onset of the disease and/or later, recurrent course of aHUS and the presence of CKD prior to the start of the Eculizumab therapy. Conclusion: The genetic profile of patients does not determine the severity and outcome of aHUS though it does affect the relapse rate. The prognosis and survival of patients with aHUS are determined by the severity of the acute period and the timeliness of the complement blocking therapy management.

Клинико-генетическая характеристика детей с подозрением на наследственные заболевания печени. Алгоритм дифференциальной диагностики

Hepatitides of unspecified etiology in children may be caused by genetic disorders. Its early detection can improve the patient management with understanding the pathogenesis, more accurately predicting the course, preventive examinations and prescribing specialized pathogenetic therapy in selected cases. However, currently there are no guidelines for the optimal diagnosis of such cases. The purpose of this research was to develop an algorithm for the differential diagnosis of hepatitides of unspecified etiology in children based on the identified clinical and genetic features of hereditary liver diseases. Materials and methods used: a single-center cohort retrospective study of 179 children with hepatitides of unspecified etiology aged 0 to 18 y/o was conducted. All patients had undergone genetic examination, based on the results of which the two groups were formed as follows: with and without genetic liver disease. Statistical analysis of the patients’ clinical, laboratory and instrumental examinations was aimed at identifying key markers for common hereditary liver diseases in different age groups as well as statistically significant differences in rare genetic reasons for hepatitis. Results: 27 different genetic liver diseases were identified in 101 (56.4%) with hepatitis of unspecified etiology. The most frequently detected diseases were Wilson's disease (41 or 40.6%), alpha-1 antitrypsin deficiency (A1AD or AATD) (9 or 8.9%) and Alagille syndrome (ALGS) (8 or 7.9%). Other hereditary pathologies occurred in isolated cases though its total incidence was nearly half of all cases (43 or 42.6%). In order to identify such cases, it is advisable to perform exome sequencing. In order to determine the indications for genetic examination, Authors have developed the mathematical model for assessing the risk of hereditary liver disease (ROC-AUC 0.787 with 95% CI: 0.696-0.877, sensitivity 69.8% with 95% CI: 57.7%-81.3%, specificity 79.2% with 95% CI: 72.3%-84.8%). Conclusion: Authors offer the suggested algorithm for differential diagnosis of hepatitides of unspecified etiology in children that includes, on the first place, the exclusion of the most common genetic liver diseases followed by exome sequencing in high-risk cases that in its turn is calculated using the developed mathematical model.

Meta-analysis of the association between sex hormones and pulmonary fibrosis

ABSTRACT Background This study aimed to investigate the association between sex hormones and the risk of pulmonary fibrosis by conducting a meta-analysis of previously published studies. Methods We executed a comprehensive search of the PubMed, Embase, Cochrane Library, and Web of Science databases to locate pertinent studies published up to April 2024. We included studies that reported the association between sex hormones and the risk of pulmonary fibrosis. Standardized mean difference (SMD) with 95% confidence intervals (CIs) were calculated using a random-effects model. Results A total of 10 articles, encompassing 1371 patients, were finally incorporated in this meta-analysis. Based on the evaluation of the included studies, it was observed that the levels of dehydroepiandrosterone sulfate (DHEA-S) (pooled SMD: −0.72, 95% CI: −1.21 to −0.24, p < 0.001), testosterone (pooled SMD: −1.25, CI: −2.39 and −0.11, p < 0.001) and estrogen (pooled SMD: −0.56, 95% CI: −0.96 to −0.15, p < 0.001) were significantly lower in patients with pulmonary fibrosis, whereas the levels of luteinizing hormone (LH) remained unaffected. Publication bias was ruled out through funnel plots. Conclusion This meta-analysis indicates that reduced levels of DHEA-S, testosterone, estrogen may serve as potential risk factors for pulmonary fibrosis. There is a pressing need for additional studies to confirm this association and explore the underlying biological mechanisms. Clinicians should recognize the potential influence of sex hormones in the etiology of pulmonary fibrosis and consider this aspect during the patient management process.

Tranexamic acid reduces perioperative blood transfusions following open radical cystectomy - a propensity-score matched analysis.

Radical cystectomy is associated with bleeding and high transfusion rates, presenting challenges in patient management. This study investigated the prophylactic use of tranexamic acid during radical cystectomy. All consecutive patients treated with radical cystectomy at a tertiary care university center were included from a prospectively maintained database. After an institutional change in the cystectomy protocol patients received 1g of intravenous bolus of tranexamic acid as prophylaxis. To prevent bias, propensity score matching was applied, accounting for differences in preoperative hemoglobin, neoadjuvant chemotherapy, tumor stage, and surgeon experience. Key outcomes included transfusion rates, complications, and occurrence of venous thromboembolism. In total, 420 patients were included in the analysis, of whom 35 received tranexamic acid. After propensity score matching, 32 patients and 32 controls were matched with regard to clinicopathologic characteristics. Tranexamic acid significantly reduced the number of patients who received transfusions compared to controls (19% [95%-Confidence interval = 8.3; 37.1] vs. 47% [29.8; 64.8]; p = 0.033). Intraoperative and postoperative transfusion rates were lower with tranexamic acid, though not statistically significant (6% [1.5; 23.2] vs. 19% [8.3; 37.1], and 16% [6.3; 33.7] vs. 38% [21.9; 56.1]; p = 0.257 and p = 0.089, respectively). The occurrence of venous thromboembolism did not differ significantly between the groups (9% [2.9; 26.7] vs. 3% [0.4; 20.9]; p = 0.606). Prophylactic tranexamic administration, using a simplified preoperative dosing regimen of 1g as a bolus, significantly lowered the rate of blood transfusion after cystectomy. This exploratory study indicates the potential of tranexamic acid in enhancing outcomes of open radical cystectomy.

Curcumin, a bioactive compound of Turmeric (Curcuma longa) and its derivatives as α-amylase and α-glucosidase inhibitors.

Diabetes mellitus (DM) is a long-term metabolic disease characterised by a controlled metabolism of fat, carbohydrates, and proteins. In recent decades, it has grown into a significant global public health issue. According to the International Diabetes Federation, there were 425 million DM globally in 2017, and the number might be increased to 629 million by 2045 (a global 48% increase). Approximately 4.2 million deaths globally attributed to DM occur before the age of 60. The existing class of anti-diabetic medications is limited by side effects, which has led to the hunt for novel inhibitors that specifically target the α-amylase and α-glucosidase enzymes. Curcumin is a small-molecular-weight compound found in the roots of the Curcuma longa L (C. longa). plant, which has been used for culinary, medicinal, and other purposes throughout Asia for thousands of years. Curcumin has potent anti-inflammatory, anti-cancer, anti-angiogenic, antispasmodic, antibacterial, and anti-parasitic qualities. Even though the potential of curcumin to cure DM has been well investigated, its low solubility, rapid metabolism, and short plasma half-life have limited its application in DM. Therefore, the objectives of this review were to review the chemical composition of C. longa, the structure of curcumin, the degradation of curcumin, and the effects of curcumin derivatives on anti-diabetic properties against α-amylase and α-glucosidase enzymes. The results showed that C. longa contains carbohydrates, moisture, protein, fat, minerals, volatiles, fibre, and curcuminoids. Among the curcuminoids, curcumin is 60-70% present in C. longa. Moreover, curcumin and its derivatives have a lot of potential for treating DM, which was highlighted in this review. This review emphasises the several biological applications of curcumin, which collectively establish the foundation for its anti-diabetic characteristics. Considering these results, curcumin derivatives may be considered as potential agents in the pharmacotherapeutic management of patients with DM.

Severe Developmental Delay and Behavior Abnormalities in a Patient with De Novo CAMK2B Mutation: A Case Report and Literature Review.

The calcium/calmodulin-dependent protein kinase II-beta (CAMK2B) gene is important for calcium signaling and glutamatergic synapses, which impacts neuroplasticity and learning. Mutations in the CAMK2B gene, which cause autosomal dominant mental retardation 54 (Online Mendelian Inheritance in Man # 617799), can have multisystemic clinical impact. Due to the rarity of CAMK2B mutations at present, case reports about patients with CAMK2B mutations are limited. The present case report describes a patient with CAMK2B-related disorder confirmed by whole exome sequencing and adds to the current information in the literature. We review three case reports in literature with detailed descriptions of patients presenting with mutations in the CAMK2B gene. While there is a broad spectrum of phenotypic presentations, there appears to be an emerging neurobehavioral phenotype. Optimal management of patients will require attention to behavioral issues as well as involvement of neuropsychiatric expertise along with other supports for development and vision abnormalities.

Anesthesia management for percutaneous mitral valve repair in a patient with mitochondrial cardiomyopathy and low cardiac function: a case report.

Mitochondrial cardiomyopathy occurs when impaired mitochondrial energy production leads to myocardial dysfunction. Anesthetic management in such cases is challenging due to risks of circulatory depression associated with anesthesia and mitochondrial dysfunction induced by anesthetics. Although there are reports of anesthetic management for patients with mitochondrial diseases, there are few reports specifically addressing cardiac anesthesia for patients with mitochondrial cardiomyopathy. We present a case where percutaneous mitral valve repair with MitraClip™ was successfully performed under remimazolam anesthesia in a patient with mitochondrial cardiomyopathy who developed functional mitral valve regurgitation due to low cardiac function and cardiomegaly. A 57-year-old woman was diagnosed with chronic cardiac failure, with a 10-year history of dilated cardiomyopathy. She was diagnosed with mitochondrial cardiomyopathy 8years ago. Over the past 2years, her cardiac failure worsened, and mitral valve regurgitation gradually developed. Surgical intervention was considered but deemed too risky due to her low cardiac function, with an ejection fraction of 26%. Therefore, percutaneous MitraClip™ implantation was selected. After securing radial artery and central venous catheterization under sedation with dexmedetomidine, anesthesia was induced with a low dose of remimazolam 4mg/kg/h. Anesthesia was maintained with remimazolam 0.35-1.0mg/kg/h and remifentanil 0.1μg/kg/min. Noradrenaline and dobutamine were administered intraoperatively, and the procedure was completed successfully without circulatory collapse. The patient recovered smoothly from anesthesia and experienced no complications. She was discharged on the eighth day after surgery. Anesthesia management with remimazolam appears to be a safe and effective for MitraClip™ implantation in patients with mitochondrial cardiomyopathy.

Side effects of Immune Checkpoint Inhibitors : Diagnostics and Management-an Update

Immune checkpoint inhibitors (ICI) represent a breakthrough in cancer therapy. They are effective in various tumor entities and can be used in more and more treatment settings. This leads to an increase in the number and complexity of cases with immune-related adverse events (irAE). The most common irAE are cutaneous, gastrointestinal and endocrine side effects, whereas less common irAE include pneumonitis, nephritis, myocarditis or neurological reactions. IrAE can usually be successfully treated, mainly with corticosteroids or other immunosuppressants, but they can also result in long-term sequelae or death. The optimal management of patients with steroid-refractory or steroid-dependent side effects still remains unclear. Broad awareness of these irAE across specialties is therefore of crucial importance to ensure early diagnosis and to improve irAE management.

Effective roles of exercise and diet adherence in non-alcoholic fatty liver disease

Non-alcoholic fatty liver disease (NAFLD) is characterized by symptoms of excessive fat accumulation and steatosis in the liver without alcohol intake in patients. The associated pathogenic mechanism is not completely understood and there are no specific drugs for patients with NAFLD. Exercise and diet adherence are the best options for the management of NAFLD patients. Questionnaire associated analysis models of adherence to these interventions are used to assess their effectiveness in the management of NAFLD patients using specificity, sensitivity, and so on. Studies have indicated that the relative ratio of NAFLD can be reduced by physical activity with diet control. In the future, the pathogenesis of NAFLD should be clarified with stratified efforts to develop appropriate drugs, and both exercise and diet adherence should be optimized using better questionnaire design and evaluation models for patients with NAFLD.

Opioid and benzodiazepine requirements in critically ill post-surgical children with down syndrome: a systematic review and meta-analysis

BackgroundDown syndrome (DS), or Trisomy 21, is defined by the existence of an additional chromosome 21. Various physiological considerations in DS patients might lead to challenges in adequate pain management and sedation after surgery. The aim of this systematic review and meta-analysis is to evaluate the variations of the requirement needed for pain management and sedation in patients with DS who have undergone surgery compared to patients without DS.MethodsA systematic review and meta-analysis of studies were conducted, focusing on critically ill patients with DS who were admitted to Intensive care units (ICUs) post-surgery and received opioids and/or benzodiazepines. Searches were conducted in four databases from their inception to November 18, 2023 (Pubmed, Scopus, Cochrane Library, and Web of Science). The primary outcome measured was the dosage of Oral Morphine Equivalent (OME) administered in the days following surgery. Fixed-effect models were used, an approach advisable when only a limited number of studies are available.Results Out of the 992 studies initially screened, the systematic review included ten studies, encompassing 730 patients, while the meta-analysis consisted of seven studies, encompassing 533 patients. Of the seven studies included in the analysis, 298 patients were identified to have DS, and 235 patients served as controls. Patients with DS showed a slight increase in OME needs on the first day, but this increase was not statistically significant (mean difference [MD] = 0.09; 95% Confidence Interval [CI]: [-0.02, 0.20]; P = 0.11). There was also no significant difference in the requirement for Midazolam on the first day among DS patients (MD = 0.01; CI [-0.16, 0.19]; P = 0.88). In addition, the duration of mechanical ventilation was not statistically significant in patients with DS compared with the control group (MD = -1.46 hours; 95% CI [-9.74, 6.82]; P = 0.73).ConclusionPatients with Down syndrome did not require more sedation or analgesia in the first three days after surgery than patients without Down syndrome. Additionally, the two groups showed no significant difference in the duration of mechanical ventilation.

Prognostic Significance of Caudal-type Homeobox Gene 2 and Sex-determining Region Y-Box 2 Immunohistochemistry Markers in Gastric Cancer – A Clinicopathological Study

Abstract Background: Gastric cancer is one of the most commonly diagnosed cancers and the third leading cause of cancer-related deaths in the world as it has a poor prognosis due to its delayed presentation. Adenocarcinoma (intestinal or diffuse type) is the most common type histologically, and tumor, node, and metastasis staging is essential for prognosis and treatment planning. Gastric cancer patients may have different clinical presentation even within the same cancer stage group, hence it is important to evaluate additional markers in such patients which can help in prognosticating them to aid in effective management of such patients. This study evaluates two new immunohistochemistry (IHC) markers and their clinical correlation which will help in prognosticating gastric cancer patients. Materials and Methods: Biopsy tissues from 30 patients between April 2016 and April 2019, who underwent upper gastrointestinal endoscopy in a tertiary care center of Armed Forces and were found to have gastric cancer, were studied. Caudal-type homeobox gene 2 (CDX2) and sex-determining region Y-box 2 (SOX2) immunoreactivity was correlated with histomorphology, clinical presentation, and staging of tumor. Results: CDX2 positivity (P = 0.002) as well as SOX2 negativity (P = 0.058) was associated with an advanced stage of disease in our study. CDX2+/SOX2− profile was also noted to be statistically correlating (P = 0.014) with poor prognosis in gastric cancer. Conclusion: Loss of SOX2 together with positive CDX2 expression had a good correlation with advanced disease and poor outcome. Further studies should be undertaken for targeted therapy for these IHC markers.

The impact of PET imaging on triple negative breast cancer: an updated evidence-based perspective.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by the absence of estrogen, progesterone, and HER2 receptors. It predominantly affects younger women and is associated with a poor prognosis. This systematic review aims to evaluate the current role of positron emission tomography (PET) in the management of TNBC patients and to identify future research directions. We systematically searched the PubMed, Scopus, and Web of Science databases up to February 2024. A team of five researchers conducted data extraction and analysis. The quality of the selected studies was assessed using a specific evaluation form. Twenty-eight studies involving 2870 TNBC patients were included in the review. Key clinical applications of PET in TNBC included predicting pathological complete response (pCR) in patients undergoing neoadjuvant chemotherapy (NAC), assessing the prognostic value of baseline PET, and initial disease staging. Two studies utilized PSMA-ligand agents, while the majority used [18F]FDG-based PET. Significant associations were found between baseline [18F]FDG uptake and molecular biomarkers such as PDL-1, androgen receptor, and Ki67. Baseline [18F]FDG PET led to the upstaging of patients from stage IIB to stage IV, influencing treatment decisions and survival outcomes. In the NAC setting, serial PET scans measuring changes in [18F]FDG uptake, indicated by maximum standardized uptake value (SUVmax), predicted pCR with varying cut-off values correlated with different response rates. Semiquantitative parameters such as metabolic tumor volume (MTV) and PET lung index were prognostic for metastatic disease. In TNBC patients, [18F]FDG PET is essential for initial disease staging in both localized and metastatic settings. It is also useful for assessing treatment response to NAC. The ability of PET to correlate metabolic activity with molecular markers and predict treatment outcomes highlights its potential in TNBC management. Further prospective studies are needed to refine these clinical indications and establish its definitive role.

Cost Analysis of Routine Histopathologic Evaluation of Specimens Following Total Ankle Arthroplasty.

Routine histopathologic examination of orthopaedic surgical specimens is a standard practice at many institutions. Previous studies have demonstrated that this practice seldom altered patient management for several orthopaedic procedures. As a result, the value of such practices has come into question. The purpose of this study is to determine the cost-effectiveness of routine histopathologic analysis of specimens obtained during total ankle arthroplasty (TAA). A retrospective analysis was performed of patients who underwent uncomplicated primary TAA at a large, academic, health system between January 2015 and December 2021. The postoperative histopathologic diagnoses were compared with the respective patient's preoperative clinical and intraoperative diagnoses. The prevalence of concordant, discrepant, and discordant diagnoses was determined. Cost-effectiveness analysis was conducted to assess the financial implications of obtaining routine specimens for histopathologic examination for TAA. A total of 85 TAAs were identified in 85 individual patients and were included in the present study. A total of 172 specimens were sent for routine histopathologic review. On histopathologic analysis, a final diagnosis was confirmed in 82 (96.5%) of the total specimens reviewed. A discrepant diagnosis was discovered in 3 (3.5%; 2 cases of gout/pseudogout and 1 case of osteonecrosis) cases and 0 (0%) discordant diagnoses were discovered, corresponding to positive and negative predictive values of 97% and 100%, respectively The total estimate of costs incurred for the routine analysis of all specimens included in the study was between $12 299.20 and 17 846.00. The estimated cost to establish each discrepant diagnosis ranged between $4099.73 and $5948.67, and the cost for a discordant diagnosis was unable to be established. Routine histopathologic analysis of specimens obtained during TAA rarely revealed a discordant diagnosis and resulted in no alterations to patients' plan of care. Furthermore, the additional costs of routine histopathologic examination are significant. As such, it is recommended that such interventions in TAA should be performed on a per-case basis at the operating surgeon's discretion.

Immune-related gene signature improves prognosis prediction in patients with breast cancer and associates it with tumor immunity and inflammatory response

BackgroundThe prognostic potential of immune-related genes, particularly immune checkpoint inhibitors (ICIs) and long non-coding RNAs (lncRNAs), is gaining attention for evaluating the prognosis of breast cancer patients.MethodsWe analyzed 23 datasets to identify 15 ICI-related mRNAs and 5 immune-related lncRNAs, creating a robust immune score (IS). This score was used to classify patients into high and low IS groups and assess their survival outcomes.ResultsPatients with high IS showed significantly poorer overall survival (OS) and progression-free survival (PFS) compared to those with low IS. Multivariate Cox regression analysis confirmed IS as an independent prognostic factor. Additionally, high IS was associated with higher mutation loads and neoantigen profiles, while low IS correlated with enhanced immune cell infiltration.ConclusionsThe immune score developed from ICI-related mRNAs and lncRNAs effectively predicts the prognosis of breast cancer patients and highlights the differential immune and inflammatory responses between patients with varying levels of immune score. This underscores the relevance of IS in guiding therapeutic decisions and tailoring patient management strategies in clinical settings.

Factors influencing the continuity of evidence-based practice in perioperative airway management for elderly patients with fractures: A qualitative study.

More and more evidence-based practices are emerging, but researchers mostly focus on short-term effects, resulting in evidence-based practices not being applied in the clinic in the long term. In this study, we took the evidence-based practice of perioperative airway management in elderly fracture patients as an example and adopted a descriptive phenomenological approach to understand the influencing factors of its sustainability to provide a reference basis for promoting the continuity of evidence-based practice in the clinic. To explore factors influencing the persistence of evidence-based practice in perioperative airway management in elderly patients with fractures. This study was qualitative research. Nine nurses who implemented evidence-based practice in the orthopedic ward of a tertiary comprehensive hospital in Shanghai from September 2023 to October 2023 were selected using purposive sampling as research subjects. Semi-structured interviews were conducted with them, and the data were analyzed using the Colaizzi phenomenological analysis method based on the three dimensions and ten factors of the NHS sustainability model. Three main themes and ten subthemes were identified: Process aspects (benefits to patients, benefits to nurses, lack of follow-up, complex processes); staff aspects (insufficient human resources, inadequate training and education, lack of leadership support); and organizational environment aspects (inadequate infrastructure, poor patient compliance, poor doctor cooperation). Human resources, training and education, leadership support, infrastructure, and patient-physician collaboration are important factors influencing the sustainability of evidence-based practice for perioperative airway management in older patients with fractures.

Delphi consensus recommendations on treatment for advanced-stage marginal zone lymphoma in South Korea.

Due to the lack of treatment guidelines for the management of advanced-stage marginal zone lymphoma (MZL), only one chemoimmunotherapy-cyclophosphamide, vincristine, and prednisone plus rituximab (R-CVP)-is reimbursed in the first-line setting in South Korea. The aim of this study was to develop a consensus-based recommendation for the treatment of patients with advanced-stage MZL. Twelve hematologist oncologists participated in a two-round Delphi process to identify consensus on the management of patients with advanced-stage MZL in South Korea. Physicians rated their level of agreement with each statement on a four-point Likert scale. Statements were divided into two sections: definitions used in clinical practice and clinical management of patients with advanced-stage MZL. Consensus was reached for 23 of 33 (69.7%) and 5 of 13 statements (38.5%) in rounds 1 and 2, respectively. There was strong consensus (91.7%) that advanced-stage MZL subtypes are defined according to the Lugano staging system. First-line systemic treatment should be prescribed for patients with symptomatic advanced-stage MZL. Although there was unanimous agreement that R-CVP is the standard first-line treatment for advanced-stage MZL, physicians also agreed that bendamustine with rituximab (BR) has greater efficacy than R-CVP as first-line treatment (91.7%). For the treatment of relapsed/refractory advanced-stage MZL, BR and R-CVP can be repeated in patients with short (< 24 months) and long remission periods (≥ 24 months), respectively. This study provides insights on the management of patients with advanced-stage MZL in South Korea. This may enhance clinical decision-making, thus improving patient outcomes.

Diagnostic accuracy of an uncorrected native T1 mapping sequence for liver fibrosis and inflammation in autoimmune hepatitis: a prospective study using histopathology as reference standard.

There is an unmet clinical need for non-invasive imaging biomarkers that could replace liver biopsy in the management of patients with autoimmune hepatitis (AIH). In this study, we sought to evaluate the diagnostic accuracy of a simple uncorrected, non-contrast T1 mapping for detecting fibrosis and inflammation in AIH patients using histopathology as a reference standard. Over 3years, 33 patients with AIH were prospectively studied using a multiparametric liver MRI protocol which included T1 mapping. Biopsies were performed up to 3months before imaging, and a standardized histopathological score for fibrosis (F0-F4) and inflammatory activity (PPA0-4) was used as a reference. Statistical analysis included independent t test, Mann-Whitney U-test, and ROC (receiver operating characteristic) analysis. T1 mapping values were significantly higher in patients with advanced fibrosis (F0-2 vs. F3-4; p < 0.015), significant fibrosis (F0-1 vs. F2-4; p < 0.005), and significant inflammatory activity (PPA 0-1 vs. PPA 2-4 p = 0.048). Moreover, the technique demonstrated a good diagnostic performance in detecting significant (AUC 0.856) and advanced fibrosis (AUC 0.835), as well as significant inflammatory activity (AUC 0.763). A rapid, simple, uncorrected, non-contrast T1 mapping sequence showed satisfactory diagnostic performance in comparison with histopathology for detecting significant tissue inflammation and fibrosis in AIH patients, being a potential non-invasive imaging biomarker for monitoring disease activity in such individuals.
