The aim of this study was to assess the ability of the modified contrast-enhanced ultrasound (CEUS) Liver Imaging Reporting and Data System (LI-RADS) to distinguish malignancy in patients without known hepatocellular carcinoma (HCC) risk factors and compare diagnostic accuracy with that of the World Federation for Ultrasound in Medicine and Biology (WFUMB) guideline across radiologists with different levels of CEUS experience.
A total of 848 individuals with no hepatitis infection presenting with 870 lesions in non-cirrhotic livers were included and divided into the Testing and Validation groups. The modified CEUS LI-RADS was proposed, including downgrading of focal nodular hyperplasia with typical features. Diagnostic performance of the modified CEUS LI-RADS was assessed in the Testing group. In the Validation group, two radiologists with more than 9 y of CEUS experience (Experts) and two radiologists with less than 6 mo of CEUS experience (Novices) used both the modified CEUS LI-RADS and the WFUMB guideline to evaluate performance in diagnosis of the lesions.
LR-5 + M (combination of modified LR-5 and modified LR-M) revealed optimal performance with a sensitivity, specificity and area under the curve (AUC) of 99.3%, 81.6% and 0.904, respectively. Novices using the modified CEUS LI-RADS outperformed those using the WFUMB guideline (AUC: 0.858 vs. 0.767, p = 0.005). Additionally, the sensitivity, specificity and AUC of Novices were comparable to those of Experts using the modified CEUS LI-RADS (94.1%, 77.6% and 0.858 vs. 96.1%, 77.6% and 0.868 for experts, respectively).
The modified CEUS LI-RADS is a valuable method for distinguishing hepatic malignancy in patients without HCC risk factors. This is particularly beneficial for radiologists with limited CEUS expertise.

Increasing evidence indicates that circadian and diurnal rhythms robustly influence stroke onset, mechanism, progression, recovery, and response to therapy in human patients. Pioneering initial investigations yielded important insights but were often single-center series, used basic imaging approaches, and used conflicting definitions of key data elements, including what constitutes daytime versus nighttime. Contemporary methodologic advances in human neurovascular investigation have the potential to substantially increase understanding, including the use of large multicenter and national data registries, detailed clinical trial data sets, analysis guided by individual patient chronotype, and multimodal computed tomographic and magnetic resonance imaging. To fully harness the power of these approaches to enhance pathophysiologic knowledge, an important foundational step is to develop standardized definitions and coding guides for data collection, permitting rapid aggregation of data acquired in different studies, and ensuring a common framework for analysis. To meet this need, the Leducq Consortium International pour la Recherche Circadienne sur l\'AVC (CIRCA) convened a Consensus Statement Working Group of leading international researchers in cerebrovascular and circadian/diurnal biology. Using an iterative, mixed-methods process, the working group developed 79 data standards, including 48 common data elements (23 new and 25 modified/unmodified from existing common data elements), 14 intervals for time-anchored analyses of different granularity, and 7 formal, validated scales. This portfolio of standardized data structures is now available to assist researchers in the design, implementation, aggregation, and interpretation of clinical, imaging, and population research related to the influence of human circadian/diurnal biology upon ischemic and hemorrhagic stroke.

The clinical benefit of LDL cholesterol (LDL-C) lowering for cardiovascular disease prevention is well documented. This paper from the Italian Study Group on Atherosclerosis, Thrombosis and Vascular Biology summarizes current recommendations for treatment of hypercholesterolemia, barriers to lipid-lowering therapy implementation and tips to overcome them, as well as available evidence on the efficacy and safety of bempedoic acid. We also report an updated therapeutic algorithm for pharmacological LDL-C lowering in view of the introduction of bempedoic acid in clinical practice.

Chronic graft-versus-host disease (cGvHD) remains a prominent barrier to allogeneic hematopoietic stem cell transplantion as the leading cause of nonrelapse mortality and significant morbidity. Tremendous progress has been achieved in both the understanding of pathophysiology and the development of new therapies for cGvHD. Although our field has historically approached treatment from an empiric position, research performed at the bedside and bench has elucidated some of the complex pathophysiology of cGvHD. From the clinical perspective, there is significant variability of disease manifestations between individual patients, pointing to diverse biological underpinnings. Capitalizing on progress made to date, the field is now focused on establishing personalized approaches to treatment. The intent of this article is to concisely review recent knowledge gained and formulate a path toward patient-specific cGvHD therapy.

BACKGROUND: When developmental dysplasia of the hip (DDH) is diagnosed during infancy, conservative management is often successful, with good long-term outcomes. In India, DDH is often not diagnosed until walking age and there are limited guidelines for its screening.
METHODS: A multidisciplinary Expert Group consisting of members of the Paediatric Orthopaedic Society of India, Indian Academy of Pediatrics, National Neonatology Forum of India, Indian Radiological and Imaging Association, Indian Federation of Ultrasound in Medicine and Biology, Federation of Obstetric and Gynaecological Societies of India, and Indian Orthopaedic Association worked collaboratively to develop surveillance guidelines for DDH.
OBJECTIVE: To enhance the early detection rate of DDH in India through development and implementation of a standardized surveillance care pathway, thus reducing the burden of late-presenting DDH.
CONCLUSIONS: Routine clinical hip examinations must be performed on all infants at birth and during immunization visits at these approximate time points: 6, 10, and 14 weeks; 6, 9, 12, 15, and 18 months of age. Assessments include Ortolani and Barlow tests for infants <14 weeks; limited hip abduction and leg length discrepancy for infants >14 weeks; and evaluation of limp in walking children. If clinical examination is abnormal or inconclusive, referral to orthopedics for further evaluation and management is recommended. In infants younger than 6 weeks with positive Barlow test but negative Ortolani test, hip ultrasound is recommended at 6 weeks of age. Infants must also be screened for DDH risk factors: breech presentation, family history of DDH, unsafe hip swaddling, and hip instability at any previous clinical examination. In infants with risk factors but normal clinical examination, further evaluation should include ultrasound taken no earlier than 6 weeks of age for infants younger than 14 weeks, ultrasound or X-ray for infants 14 weeks to 6 months of age, and X-ray for infants older than 6 months. Referral to an orthopedic surgeon is recommended if radiological tests are abnormal.

Heart failure (HF) is a common cause of cardiovascular mortality and morbidity. Despite advances in treatment, the prognosis remains poor. Sodium-glucose co-transporter 2 (SGLT-2) inhibitors decrease HF events by 27-39% in high-risk patients with type 2 diabetes mellitus (T2DM). Moreover, the DAPA-HF and EMPEROR-Reduced studies randomized patients with HF with reduced ejection fraction (HFrEF) with or without diabetes mellitus to receive guideline-directed medical therapy versus guideline-directed medical therapy plus an SGLT-2 inhibitor. Both studies showed the benefits of SGLT-2 inhibitors. In addition, SGLT-2 inhibitors have shown improvement according to the EMPEROR-Preserved study of HF with preserved ejection fraction (HFpEF). Therefore, a panel of cardiology experts from the Egyptian Atherosclerosis and Vascular Biology Association (EAVA) revised the literature for SGLT-2 inhibitors in HF, along with the recommended indications and contraindications, and this article presents their consensus on the topic. The panel concluded that SGLT-2 inhibitors have significantly benefited patients with chronic HFrEF, as indicated through the DAPA-HF and EMPEROR-Reduced trials. The panel recommended early use of dapagliflozin 10 mg or empagliflozin 10 mg in patients with symptomatic chronic HFrEF, whether diabetic or non-diabetic, to ameliorate HF hospitalization rate, mortality, symptoms, and decline in renal function.

In the last decade, direct oral anticoagulants (DOACs) have entered the clinical practice of different specialists for the prevention of cardioembolic stroke in patients with non-valvular atrial fibrillation (NVAF) and the prevention and treatment of venous thromboembolism (VTE). Owing to the persistent uncertainties about the use of DOACs in daily clinical scenarios not fully explored in the clinical trials, we conducted a national Delphi consensus regarding issues deemed interesting by the Italian Atherosclerosis, Thrombosis and Vascular Biology (ATBV) Study Group in relation to: (i) elderly and/or frail patients; (ii) chronic kidney disease; (iii) drug-drug interactions; (iv) lower doses and safety; (v) criteria for choosing individual drugs and compliance; (vi) VTE in the cancer patient. Eighty-four Italian clinicians (cardiologists, internists, geriatricians, neurologists and hematologists) expressed their level of agreement on each statement using a 5-point Likert scale (1: very much in disagreement, 2: disagreement, 3: partial agreement, 4: agreement, 5: very much in agreement). In particular, 1-2 selections were considered as disagreement, while 3-5 selections were considered as agreement. A ≥66% agreement between the participants for each statement was considered consensus. In general, a broad and general awareness and sharing of the methods of use of DOACs emerged from our initiative, and in particular their preferential indication in the elderly population and in frail patients or with renal insufficiency or oncological, always following the prescription indications and dose reduction criteria. The importance of being aware of drug-drug interactions has also been underlined in a concordant way, as well as simplicity of treatment in the multi-treated patient. In view of the persistent, albeit limited (12%), absence of consensus on some issues, with regard to the frail patient, drug-food interactions and availability of antidote, the acquisition of further evidence and a persistent educational effort are nonetheless indicated.

Basal cell carcinoma (BCC) is the most common skin malignancy afflicting modern Australian society. The most influential response to rising BCC incidence rates has been through public health primary prevention campaigns (PPC) which have persevered since the 1980s. These campaigns are widely heralded a success but clinical data quantifying these benefits are limited due to an absence of legislation around BCC reporting. A non-systematic search of the literature was conducted identifying articles investigating the incidence and clinical characteristics of BCC over the past 40 years, as well as the economic viability of the PPC. There is robust evidence supporting stabilizing rates of BCC incidence in Australia. Similarly, multiple studies have shown the economic benefits of PPC through cost analysis. Anatomical and histological data are reported inconsistently, consequently limiting analysis of changes in BCC clinical characteristics. The consensus throughout the literature is that BCC is a significant public health issue that requires legislative reform. This narrative literature review serves to highlight the need for statutory changes around non-melanocytic skin cancer data collection to enable appropriate analysis and evaluation of current management strategies.

BACKGROUND: International consensus criteria (ICC) have redefined borderline resectability for pancreatic ductal adenocarcinoma (PDAC) according to three dimensions: anatomical (BR-A), biological (BR-B), and conditional (BR-C). The present definition acknowledges that resectability is not just about the anatomic relationship between the tumour and vessels but that biological and conditional dimensions also are important.
METHODS: Patients\' tumours were retrospectively defined borderline resectable according to ICC. The study cohort was grouped into either BR-A or BR-B and compared with patients considered primarily resectable (R). Differences in postoperative complications, pathological reports, overall (OS), and disease-free survival were assessed.
RESULTS: A total of 345 patients underwent resection for PDAC. By applying ICC in routine preoperative assessment, 30 patients were classified as stage BR-A and 62 patients as stage BR-B. In total, 253 patients were considered R. The cohort did not contain BR-C patients. No differences in postoperative complications were detected. Median OS was significantly shorter in BR-A (15 months) and BR-B (12 months) compared with R (20 months) patients (BR-A vs. R: p = 0.09 and BR-B vs. R: p < 0.001). CA19-9, as the determining factor of BR-B patients, turned out to be an independent prognostic risk factor for OS.
CONCLUSIONS: Preoperative staging defining surgical resectability in PDAC according to ICC is crucial for patient survival. Patients with PDAC BR-B should be considered for multimodal neoadjuvant therapy even if considered anatomically resectable.

Control of bovine viral diarrhea virus (BVDV) in cattle populations across most of the world has remained elusive in spite of advances in knowledge about this viral pathogen. A central feature of virus perseverance in cattle herds is the unique mechanism of persistent infection. Managing BVDV infection in herds involves controlling persistently infected carrier animals using a multidimensional approach of vaccination, biosecurity, and identification of BVDV reservoirs. A decade has passed since the original American College of Veterinary Internal Medicine consensus statement on BVDV. While much has remained the same with respect to clinical signs of disease, pathogenesis of infection including persistent infection, and diagnosis, scientific articles published since 2010 have led to a greater understanding of difficulties associated with control of BVDV. This consensus statement update on BVDV presents greater focus on topics currently relevant to the biology and control of this viral pathogen of cattle, including changes in virus subpopulations, infection in heterologous hosts, immunosuppression, and vaccination.
