Integrative multiomic analysis identifies distinct molecular subtypes of NAFLD in a Chinese population.

Nonalcoholic fatty liver disease (NAFLD) has become a common health care burden worldwide. The high heterogeneity of NAFLD remains elusive and impairs outcomes of clinical diagnosis and pharmacotherapy. Several NAFLD classifications have been proposed on the basis of clinical, genetic, alcoholic, or serum metabolic analyses. Yet, accurately predicting the progression of NAFLD to cirrhosis or hepatocellular carcinoma (HCC) in patients remains a challenge. Here, on the basis of a Chinese cohort of patients, we classified NAFLD into three distinct molecular subtypes (NAFLD-mSI, NAFLD-mSII, and NAFLD-mSIII) using integrative multiomics including whole-genome sequencing (WGS), proteomics, phosphoproteomics, lipidomics, and metabolomics across a broad range of liver, blood, and urine specimens. We found that NAFLD-mSI had higher expression of CYP1A2 and CYP3A4, which alleviate hepatic steatosis through mediating free fatty acid/bile acid-mTOR-FXR/PPARα signaling. NAFLD-mSII displayed an elevated risk of liver cirrhosis along with increased hepatic infiltration of M1 and M2 macrophages because of lipid-triggered hepatic CCL2 and CRP production. NAFLD-mSIII exhibited a potential risk for HCC development by increased transcription of CEBPB- and ERCC3-regulated oncogenes because of activation of the EGF-EGFR/CHKA/PI3K-PDK1-AKT cascade. Next, we validated the existence of these three NAFLD molecular subtypes in an external cohort comprising 92 patients with NAFLD across three different Chinese hospitals. These findings may aid in understanding the molecular features underlying NAFLD heterogeneity, thereby facilitating clinical diagnosis and treatment strategies with the aim of preventing the development of liver cirrhosis and HCC.

Computerized tomography features acting as predictors for invasive therapy in the management of Crohn's disease-related spontaneous intra-abdominal abscess: experience from long-term follow-up.

Decision-making in the management of Crohn's disease (CD)-related spontaneous intra-abdominal abscess (IAA) is challenging. This study aims to reveal predictive factors for percutaneous drainage and/or surgery in the treatment of CD-related spontaneous IAA through long-term follow-up. Data were collected, including clinical manifestations, radiography and treatment strategies, in Chinese patients with CD-related IAA in a tertiary medical center. Univariate and Multivariate Cox analysis were conducted to identify predictors for invasive therapy. Altogether, 48 CD patients were identified as having IAA through enhanced CT scans. The median follow-up time was 45.0 (23.3, 58.0) months. 23 (47.9%) patients underwent conservative medical treatment, and 25 (52.1%) patients underwent percutaneous drainage and/or surgical intervention (invasive treatment group). The 1-, 2-, and 5-year overall survival rates without invasive treatment were 75.0%, 56.1%, and 46.1%, respectively. On univariate Cox analysis, the computerized tomography (CT) features including nonperienteric abscess (HR: 4.22, 95% CI: 1.81-9.86, p = 0.001), max abscess diameter (HR: 1.01, 95% CI: 1.00-1.02, p<0.001) and width of sinus (HR: 1.27, 95% CI: 1.10-1.46, p = 0.001) were significantly associated with invasive treatment. Nonperienteric abscess was significantly associated with invasive treatment on multivariate Cox analysis (HR: 3.11, 95% CI: 1.25-7.71, p = 0.015). A score model was built by width of sinus, location of abscess and max abscess diameter to predict invasive treatment. The AUC of ROC, sensitivity and specificity were 0.892, 80.0% and 90.9% respectively. More than half of CD-related IAA patients needed invasive therapy within 5-year follow-up. The CT features including nonperienteric abscess, larger maximum abscess diameter and width of sinus suggested a more aggressive approach to invasive treatment.

Clinical characteristics and short-term outcomes of patients with critical acute pulmonary embolism requiring extracorporeal membrane oxygenation: from the COMMAND VTE Registry-2

BackgroundExtracorporeal membrane oxygenation (ECMO) might be required as a treatment option in patients with critical pulmonary embolism (PE). However, the clinical features and outcomes of the use of ECMO for critical acute PE are still limited. The present study aimed to clarify the clinical characteristics, management strategies and outcomes of patients with acute PE requiring ECMO in the current era using data from a large-scale observational database.MethodsWe analyzed the data of the COMMAND VTE Registry-2: a physician-initiated, multicenter, retrospective cohort study enrolling consecutive patients with acute symptomatic venous thromboembolism (VTE). Among 2035 patients with acute symptomatic PE, there were 76 patients (3.7%) requiring ECMO.ResultsOverall, the mean age was 58.4 years, and 34 patients (44.7%) were men. Cardiac arrest or circulatory collapse at diagnosis was reported in 67 patients (88.2%). The 30-day incidence of all-cause death was 30.3%, which were all PE-related deaths. The 30-day incidence of major bleeding was 54.0%, and the vast majority of bleedings were procedure site-related bleeding events and surgery-related bleeding (22.4%). The 30-day incidence of all-cause death was 6.3% in 16 patients with surgical intervention, 43.8% in 16 patients with catheter intervention, 25.0% in 16 patients with thrombolytic therapy, and 39.3% in 28 patients with anticoagulation only.ConclusionsThe current large real-world VTE registry in Japan revealed clinical features and outcomes of critical acute PE requiring ECMO in the current era, which suggested several unmet needs for future clinical trials.

Clinical Strategies for Identifying Pediatric Patients with Tuberculosis at Risk of Developing Depressive Disorders

Background: Tuberculosis remains a major global public health problem, affecting millions of people every year, including children. At the same time, depressive disorders are among the most common mental disorders in children and adolescents, significantly influencing their quality of life and development. The intersection between these two pathologies—tuberculosis and depressive disorders—in pediatric patients raises complex clinical challenges that require effective identification and intervention strategies. Materials and Methods: A total sample of 190 patients aged between 7 and 18 years who presented to Galati “St. Spiridon” Pneumophthisiology Hospital between January 2019 and December 2021 was used. Objective: The main objective of this paper is to achieve a predictive score of depressive disorders in pediatric patients diagnosed with a form of tuberculosis. This score is particularly important because it helps to identify and treat early depressive disorders in children previously diagnosed with tuberculosis, resulting in increased compliance with anti-tuberculosis treatment, decreased dropout rate, and an optimal duration of hospitalization and surveillance, which positively influences the incidence of tuberculosis. Results: The final score is determined by a rating of a total of 9 points: if the value is below 4 points, there is a minor risk of affective disorders; if the value is between 4 and 6 points, there is a medium risk of affective disorders; if the value is above 6 points, there is a severe risk of affective disorders. Conclusions: A detailed clinical assessment, the usage of screening tools, long-term monitoring, multidisciplinary interventions, and family support are essential to ensure an effective management and to improve the life quality of these children.

Lipid-lowering drugs, circulating inflammatory factors, and atrial fibrillation: a mediation Mendelian randomization study

BackgroundPrevious studies have shown an association between lipid-lowering drugs, circulating inflammatory factors, and atrial fibrillation (AF), but the specific effects of lipid-lowering drugs on AF and whether they can be mediated by circulating inflammatory factors remain unclear.MethodsWe collected 10 genetic variants encoding lipid-lowering drug targets (LDLR, HMGCR, PCSK9, NPC1L1, APOB, APOB, ABCG5, ABCG8, LPL, APOC3, and PPARA) and AF based on genome-wide association study (GWAS) summary statistics. Drug target Mendelian randomization (MR) was used to explore the causal relationship between lipid-lowering drugs and AF. In addition, we performed a mediation analysis of 91 circulating inflammatory factors to explore potential mediators. Sensitivity analyses were performed to verify the reliability of the MR Results by MR-Egger intercept test, Cochran's Q test and leave-one-out test.ResultsThe results of IVW method showed that LPL agonist had a protective effect on AF(OR = 0. 854, 95%CI: 0.816–0.894, P = 1.844E-11). However, the other nine lipid-lowering drug targets had no significant effect on AF. Notably, we found a mediator role of Fibroblast Growth Factor 5 (FGF5) in the protective effect of LPL agonist on AF with a mediator ratio of 9.22%. Sensitivity analyses supported the robustness of our findings, indicating a possible mediating pathway by which LPL agonists affect the risk of AF.ConclusionOur study provides new insights into the complex interactions among lipid-lowering agents, circulating inflammatory factors and AF, and also identified a potential mediating role of FGF5 in the pathogenesis of AF. Our findings highlight the potential of LPL agonists and targeting specific inflammatory factors for therapeutic intervention in AF, providing promising avenues for future research and clinical strategies for the management and prevention of AF.

Machine Learning in Vascular Medicine: Optimizing Clinical Strategies for Peripheral Artery Disease

Abstract Purpose of Review Peripheral Artery Disease (PAD), a condition affecting millions of patients, is often underdiagnosed due to a lack of symptoms in the early stages and management can be complex given differences in genetic and phenotypic characteristics. This review aims to provide readers with an update on the utility of machine learning (ML) in the management of PAD. Recent Findings Recent research leveraging electronic health record (EHR) data and ML algorithms have demonstrated significant advances in the potential use of automated systems, namely artificial intelligence (AI), to accurately identify patients who might benefit from further PAD screening. Additionally, deep learning algorithms can be used on imaging data to assist in PAD diagnosis and automate clinical risk stratification. ML models can predict major adverse cardiovascular events (MACE) and major adverse limb events (MALE) with considerable accuracy, with many studies also demonstrating the ability to more accurately risk stratify patients for deleterious outcomes after surgical intervention. These predictions can assist physicians in developing more patient-centric treatment plans and allow for earlier, more aggressive management of modifiable risk-factors in high-risk patients. The use of proteomic biomarkers in ML models offers a valuable addition to traditional screening and stratification paradigms, though clinical utility may be limited by cost and accessibility. Summary The application of AI to the care of PAD patients may enable earlier diagnosis and more accurate risk stratification, leveraging readily available EHR and imaging data, and there is a burgeoning interest in incorporating biological data for further refinement. Thus, the promise of precision PAD care grows closer. Future research should focus on validating these models via real-world integration into clinical practice and prospective evaluation of the impact of this new care paradigm.

Association of cumulative methylprednisolone dosages with mortality risk from pneumonia in connective tissue disease patients

Corticosteroid is essential in the treatment regimen for connective tissue disease (CTD); however, its long-term use poses significant risks, including pulmonary infections. The relationship between cumulative corticosteroid doses and adverse pneumonia outcomes requires further investigation. This study aimed to explore the association between cumulative methylprednisolone dosages (CMD) and pneumonia mortality risks among CTD patients. We conducted a retrospective analysis of data from CTD patients treated with intravenous or oral corticosteroids across six academic hospitals over approximately five years in China. We evaluated follow-up outcomes at 30 and 90 days after the onset of pneumonia. Piecewise linear regression, Cox regression analysis, and survival analysis were employed to investigate the relationship between CMD and 30-day and 90-day mortality risks. Among 335 CTD patients with pneumonia, the mean CMD was 12 g. The 30-day and 90-day mortality rates were 25.07% and 29.55%, respectively. After adjusting for potential confounders, smooth curve fitting analysis revealed a specific nonlinear relationship between CMD and 30-day and 90-day mortality risks. Cox regression analysis indicated that the lowest pneumonia mortality risk occurred when CMD ranged from 11 to 24 g (30-day adjusted hazard ratio (aHR) 0.33, 95% CI 0.14–0.77; 90-day aHR 0.37, 95% CI 0.17–0.81). Patients in the 11–24 g CMD group demonstrated significantly lower cumulative hazard and death rates compared to both the low CMD (< 11 g) and high CMD (> 24 g) groups (P < 0.05). Furthermore, interaction testing suggested that CMD’s negative impact on pneumonia mortality risks was more pronounced in community-acquired pneumonia (CAP) compared to hospital-acquired pneumonia (P for interaction < 0.05). CMD shows a distinct nonlinear relationship with 30-day and 90-day pneumonia mortality risks, with potentially lower risks observed within the 11–24 g CMD range. Moreover, the varying impact of CMD on CAP mortality risk warrants further consideration in clinical management strategies.

Intranodal Hemangioma: Case Report and Systematic Review

ABSTRACT Background: Intranodal hemangiomas are rare benign vascular tumors of the lymph nodes, often misdiagnosed as malignant lymphadenopathies due to their clinical and radiological features. This case report and systematic review aim to elucidate the epidemiology, clinical profile, and therapeutic interventions for intranodal hemangioma, enhancing diagnostic accuracy and management. Methods: A systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Searches were conducted in PubMed, Scopus, Web of Science, and Google Scholar up to March 15, 2024, using keywords like “intranodal hemangioma,” “primary intranodal hemangioma,” “nodal hemangioma,” “vascular tumor,” and “lymph node hemangioma.” Inclusion criteria included studies on clinical presentation, diagnostic strategies, and therapeutic interventions for intranodal hemangioma in patients of all ages. Excluded were reviews, opinion pieces, non-English studies, cases of hemangioendothelioma, sclerosing hemangioma, and animal studies. Key aspects analyzed included demographics, clinical presentation, management strategies, and histopathological findings. Results: Our case involves a 3-year-old female with a submandibular mass, initially diagnosed with hemangioma. After no response to beta-blocker therapy and conflicting imaging results, surgical excision was performed. Histopathology confirmed intranodal hemangioma. From 233 records, 19 publications (36 patients, including our case) met the inclusion criteria. The review shows common clinical presentations as painless, slowly enlarging lymph nodes, primarily in the cervical and axillary regions. Diagnostic challenges often require imaging and biopsy to differentiate from malignancies. Conclusion: Recognizing intranodal hemangiomas, particularly in childhood, is crucial to prevent misdiagnosis and inappropriate treatment. The rarity of these tumors in childhood and their clinical presentation similar to malignancies in older patients make diagnosis challenging without widespread awareness. Surgical excision remains the mainstay of both diagnosis and treatment, often leading to favorable outcomes.

Characteristics and Outcomes of ICU-admitted COVID-19 Patients in the Omicron and Alpha-dominated periods.

Comparing the outcomes of intensive care unit (ICU) admitted COVID-19 patients during the Alpha and Omicron-dominated periods. Patients with critical COVID-19 disease, requiring ICU admission from May to September 2021 and February to August 2022, were enrolled from a single medical center in Northern Taiwan. Clinical demographics, comorbidities, disease severity, and management strategies were recorded. The 28-day mortality from the two periods were compared both in the original and propensity score (PS)-matched cohort. Of 231 patients, 72 (31.2%) were from the Alpha period and 159 (68.8%) from the Omicron period. Patients in the Omicron period were older, had a lower body mass index, more comorbidities, higher disease severities, and increased 28-day mortality (26.4% vs. 13.9%, p=0.035). In multivariable analysis, the Omicron-dominated period was not identified as an independent factor associated with increased 28-day mortality. COVID-19 patients in Alpha- and Omicron-dominated periods had comparable 28-day mortality in PS-matched cohort (12.1% vs. 18.2%, p=0.733). Independent factors associated with 28-day mortality were a lower PF ratio (PF ratio <100, adjusted odds ratio [aOR] 2.68, 95% confidence interval, CI 1.21-5.94), septic shock ([aOR] 2.39, 95% CI 1.12-5.09) and absence of remdesivir ([aOR] 0.36, 95% CI 0.16-0.83). While patients in the Omicron period exhibited greater severity, the variant was not independently linked to higher 28-day mortality in ICU-admitted patients.

Supporting cancer-related fatigue self-management: A conversation analytic study of nurse counsellor and cancer survivor consultations.

PurposeCancer-related fatigue (CRF) is a prevalent and distressing symptom experienced by people affected by cancer. A breakdown of the clinician-patient partnership and suboptimal clinician communication has been identified as a significant barrier to implementing into clinical practice effective self-management strategies for CRF. This study examined the use and impact of communication practices employed by trained cancer nurse counsellors when providing CRF self-management support to cancer survivors. MethodsInteractions from 41 telehealth consultations between three nurse counsellors and 23 cancer survivors in a CRF self-management support clinic in Queensland, Australia were recorded and analysed using conversation analysis methods. ResultsAnalysis found that in instances where nurses established the agenda of a consultation from the outset of a session (e.g., focusing on fatigue self-management support), cancer survivors displayed clearer understandings of their self-management role, the tasks, and goals of a session; and displayed less difficulty engaging in supportive care discussions. Furthermore, clinicians used formulation practices, such as summarising dialogue, to sustain focus on fatigue during consultations, and to close discussion matters not ostensibly pertinent to fatigue self-management planning supporting the goals of the CRF SMS clinic consultations. ConclusionFor supportive care sessions targeting fatigue management, clinicians should ideally focus discussion on CRF support early, by clearly introducing the agenda at the outset of the consultation while also asking for client agreement. Periodically summarising patient’s talk allows clinicians to maintain a focus on matters relevant for self-management fatigue planning and provide support within the typically constrained timeframes allocated for addressing CRF.

Asiatic acid alleviates subarachnoid hemorrhage-induced brain injury in rats by inhibiting ferroptosis of neurons via targeting Acyl-coenzyme A Oxidase 1

The occurrence of subarachnoid hemorrhage (SAH) can lead to brain injury, which is a fatal condition with limited effective clinical intervention strategies. The naturally occurring component Asiatic acid (AA), found in the tropical plant Centella asiatica, has been reported to possess neuroprotective properties. The objective of this study was to evaluate the neuroprotective effect of AA following SAH and investigate its potential mechanisms. The SAH model was established in male Sprague-Dawley (SD) rats through intravascular perforation, following a standardized protocol. The administration of AA was performed via gavage following SAH. A lentiviral vector was constructed and utilized for the knockdown of Acyl Coenzyme A Oxidase 1 (ACOX1) Firstly, AA treatment effectively improves brain neurological deficit, neuronal damage, and iron deposition induced by SAH. Furthermore, it has been demonstrated that AA directly interacts with ACOX1, which exhibits decreased expression in neurons following SAH. Additionally, our study reveals AA can reverse SAH-induced reduction in ACOX1 expression, concurrently ameliorating neuronal ferroptosis. This improvement is evidenced by reduced lipid peroxidation, including mitigated GSH depletion, decreased MDA production, and increased GPX4 content and activity. Also, AA enhances mitochondrial constriction while alleviating cristae disruption induced by SAH, providing crucial insights into its neuroprotective effects against neuronal ferroptosis in SAH. Moreover, when ACOX1 is knocked down, the neuroprotective effects of AA are weakened. Collectively, this study elucidated the neuroprotective effect of AA by inhibiting neuronal cell ferroptosis through targeting ACOX1. These findings suggest that AA holds promise as a potential therapeutic candidate for ameliorating SAH-induced brain injury.

Cyclanoline Reverses Cisplatin Resistance in Bladder Cancer Cells by Inhibiting the JAK2/STAT3 Pathway.

Cisplatin is a key therapeutic agent for bladder cancer, yet the emergence of cisplatin resistance presents a significant clinical challenge. This study aims to investigate the potential and mechanisms of cyclanoline (Cyc) in overcoming cisplatin resistance. Cisplatin-resistant T24 and BIU-87 cell models (T24/DR and BIU-87/DR) were established by increasing gradual concentration. Western Blot (WB) assessed the phosphorylation of STAT3, JAK2, and JAK3. T24/DR and BIU-87/DR cell lines were treated with selective STAT3 phosphorylation modulators, and cell viability was evaluated by CCK-8. Cells were subjected to cisplatin, Cyc, or their combination. Immunofluorescence (IHC) examined p-STAT3 expression. Protein and mRNA levels of apoptosis-related and cell cycle-related factors were measured. Changes in proliferation, invasion, migration, apoptosis, and cell cycle were monitored. In vivo, subcutaneous tumor transplantation models in nude mice were established, assessing tumor volume and weight. Changes in bladder cancer tissues were observed through HE staining, and the p-STAT3 was assessed via WB and IHC. Cisplatin-resistant cell lines were successfully established, demonstrating increased phosphorylation of STAT3, JAK2, and JAK3. Cisplatin or Cyc treatment decreased p-STAT3, inhibited invasion and migration, and induced apoptosis and cell cycle arrest in the G0/G1 phase in vitro. In vivo, tumor growth was significantly suppressed, with extensive tumor cell death. IHC and WB consistently showed a substantial downregulation of STAT3 phosphorylation. These changes were more pronounced when cisplatin and Cyc were administered in combination. Cyc reverses cisplatin resistance via JAK/STAT3 inhibition in bladder cancer, offering a potential clinical strategy to enhance cisplatin efficacy in treating bladder cancer.

Diagnosis and management of infections related to spinal pain interventions

Although relatively rare, infections related to spinal pain interventions pose significant risks with an increase in the frequency of these procedures. This review investigates the incidence, risk factors, and management of infections following spinal pain interventions, such as epidural steroid injections, nucleoplasty, and facet joint injections. Most of the existing literature comprises case reports and retrospective studies with limited prospective research, owing to the nature of these infections. Our analysis revealed that while the overall infection rate is low, potential complications, such as epidural abscesses and spondylodiscitis, can be severe and life-threatening. The risk factors include advanced age, diabetes, immunosuppression, and multiple spinal procedures. Early diagnosis and timely intervention are critical to prevent long-term morbidity. These findings emphasize the importance of developing standardized diagnostic algorithms and treatment guidelines to support clinicians in managing these infections effectively. Future research should focus on large-scale studies to understand the impact of these infections better and refine clinical management strategies.

Histopathological patterns of gastrointestinal lesions: Insights from a Tertiary Care Centre

Gastrointestinal (GI) lesions are a common clinical concern with significant implications for patient health, particularly in cases involving malignancies. Understanding the histopathological spectrum of these lesions is crucial for improving diagnosis and treatment strategies. This study aimed to investigate the histopathological spectrum of gastrointestinal lesions at a tertiary care center, focusing on the prevalence of different types of lesions and their distribution according to clinicopathological parameters. Methods: This cross-sectional study was conducted over a one-year period, from November 2022, to October 2023, at the Department of Pathology, Rohilkhand Medical College and Hospital, Bareilly, UP. A total of 100 patients with clinically suspected GI lesions were included. Biopsy specimens were collected and analyzed using standard histopathological techniques. The data were analyzed to determine the frequency of different types of GI lesions and their correlation with clinical features. Results: The study found that inflammatory lesions were the most prevalent, accounting for 57% of the cases. Malignant lesions were identified in 35% of the patients, with adenocarcinoma being the most common malignancy, especially in the colon, representing 57.14% of malignant cases. The small intestine was the most frequently affected anatomical site, involved in 33% of the cases, followed by the appendix at 22%. The majority of patients were middle-aged males, with a significant correlation between the type of lesion and gender. Conclusion: This study highlights the significant burden of gastrointestinal lesions, particularly inflammatory and malignant lesions, in the studied population. The findings underscore the importance of early detection and intervention to prevent the progression of these lesions, particularly in high-risk groups such as older males. Enhanced clinical management strategies are needed to address the substantial impact of GI pathologies on patient health.

Primary seminal vesicle diffuse large B-cell lymphoma: a case report and review of the literatures

Primary seminal vesicle lymphoma is a remarkably rare condition, predominantly manifesting as diffuse large B-cell lymphoma. Due to its rarity and nonspecific clinical presentations, it is often misdiagnosed or overlooked. Here, we report a case of a 68-year-old male diagnosed with primary seminal vesicle lymphoma, coinciding with prostate cancer. The diagnosis followed initial findings of elevated prostate-specific antigen levels and abnormal magnetic resonance imaging of the prostate and left seminal vesicle. Suspicion of prostate cancer led to a radical resection of both the prostate and seminal vesicle. Subsequent pathological examination and next-generation sequencing post-surgery confirmed the diagnosis of primary seminal vesicle diffuse large B-cell lymphoma, characterized by CD79B mutation type (MCD type). The patient was treated with six cycles of the R-CHOP regimen (rituximab, cyclophosphamide, vincristine, doxorubicin, prednisone), achieving complete metabolic remission as confirmed by positron emission tomography-computed tomography. Fifteen months post-treatment, the patient’s condition remains favorable. Through our literature review of additional six cases of primary seminal vesicle lymphoma, we aim to elucidate the typical clinical presentations, imaging features, pathological characteristics, genetic mutations, and therapeutic strategies, aiming to contribute to better detection and management of this rare malignancy. This case underscores the diagnostic challenges and emphasizes the necessity for heightened clinical suspicion and definitive pathological examination in the management of primary seminal vesicle lymphoma.

Acute Myocardial Infarction in the Context of Diabetic Ketoacidosis: Pathophysiological Interactions, Clinical Manifestations, and Therapeutic Considerations

Acute myocardial infarction (AMI) and diabetic ketoacidosis (DKA) are two critical conditions that can coexist with significant morbidity and mortality. AMI is a leading cause of cardiovascular death, while DKA is a severe complication of uncontrolled diabetes mellitus, characterized by hyperglycemia, metabolic acidosis, and ketonemia. The convergence of these conditions presents unique challenges in diagnosis and management, as the metabolic disturbances of DKA can exacerbate myocardial ischemia and contribute to poor clinical outcomes. This article aims to explore the pathophysiological interplay between AMI and DKA, focusing on their shared risk factors, metabolic derangements, and the impact of hyperglycemia and ketosis on myocardial oxygen supply and demand. Furthermore, we discuss the clinical presentation, diagnostic strategies, and therapeutic approaches tailored to this dual pathology. Early recognition and prompt intervention are crucial to improving prognosis in patients with coexisting AMI and DKA. Multidisciplinary management involving cardiologists, endocrinologists, and intensivists is essential to mitigate the adverse outcomes of this complex clinical scenario.

Seven-year overview of antimicrobial resistance in diarrheagenic Escherichia coli from sporadic human diarrhea cases in 20 Chinese provinces

Diarrheagenic Escherichia coli is one of the most prevalent foodborne pathogens and poses significant clinical challenges due to increasing rates of antibiotic resistance. In this study, 9,068 diarrheagenic E. coli isolates from sporadic diarrhea cases across 20 provinces of China from 2016 to 2022 were systematically analyzed to determine the prevalence and distribution of resistance. A total of 14 antibiotics were included in the antimicrobial resistance surveillance. Antimicrobial susceptibility testing indicated that the majority of the isolates (89.3%) were resistant to at least one antimicrobial agent, with a significant proportion (60.3%) demonstrating multidrug resistance. Isolates showed high levels of resistance to ampicillin (68.2%) and high sensitivity to imipenem (97.0%). Over the 7 years, an increasing trend in resistance to cefoxitin and chloramphenicol among the isolates was found. Enteroaggregative E. coli was identified as the predominant pathotype. Furthermore, antimicrobial resistance rates were higher among the isolates from infants under 1 year of age compared to other populations and resistance levels differed among pathotypes. In summary, our findings revealed the detailed resistance characteristics of diarrheagenic E. coli strains isolated from human sporadic diarrhea cases in China, offering valuable insights that can inform clinical antibiotic treatment strategies and priorities.
