Macrophages as Potential Therapeutic Targets in Acute Myeloid Leukemia.

Acute myeloid leukemia (AML) is a heterogenous malignant hemopathy, and although new drugs have emerged recently, current treatment options still show limited efficacy. Therapy resistance remains a major concern due to its contribution to treatment failure, disease relapse, and increased mortality among patients. The underlying mechanisms of resistance to therapy are not fully understood, and it is crucial to address this challenge to improve therapy.

Advancements and challenges in Shear-Wave Elastography of tendons: a comprehensive review.

Shear-Wave Elastography (SWE) has emerged as a promising non-invasive imaging technique for assessing the mechanical properties of tendons, particularly larger and more superficially located tendons of the body. Despite its potential, significant variability in SWE measurements exists due to differences in protocols, positioning, and equipment. Standardizing these factors, enhancing operator training, and reporting reliability metrics are crucial to improve the consistency and comparability of SWE data.

A new form of severe acute localized reactions following intra-articular hyaluronic acid injections in knee osteoarthritis. A case report.

Intra-articular hyaluronic acid (HA) injections are widely used for the treatment of symptomatic knee osteoarthritis. Adverse reactions were described in a limited number of patients and consist in local inflammatory reactions and severe acute inflammatory reactions (pseudosepsis). We present the case of a 71-year-old woman who experienced a severe acute adverse effect immediately (within minutes) following intraarticular HA administration, attributed to HA precipitation.

Material And Methods: Serum CXCL13 chemokine was assessed in 33 patients with pSS [7 with parotid NHL complication (pSS+NHL subgroup) and 26 without NHL (pSS-NHL subgroup)] and 30 healthy subjects.

Relationship between Osteopontin and Bone Mineral Density.

Recent studies suggest that osteopontin (OPN) could be used as an early marker for the diagnosis of bone disorders. Considering the contradictory opinions in the literature, the objective of this systematic review is to analyse the current information regarding the relationship between OPN and bone mineral density (BMD), which represents an important process in the development of osteoporosis. We performed a literature search of clinical trials using the PubMed database, published between 1999-2020, and identified 7 studies that were eligible for analysis.

The "starry night" (diffuse microcalcific myopathy) - thousands of muscle microcalcifications after 30 years of Trichinella infection detected by ultrasound.

Trichinellosis, a parasitosis transmitted through consumption of raw or undercooked meat from pigs and game animals, is responsible for a specific myositis. The calcifications of infected myocytes and larva can be detected during many years postin-fection. We present the case of a male patient with a history of severe trichinellosis with disease onset 30 years ago, presenting with generalized muscle microcalcifications detected during musculoskeletal ultrasound evaluation.

After an extensive literature review, the recommendations have been developed according to the Oxford Centre for Evidence-based Medicine and GRADE criteria and the consensus level was established through a Delphi process.

Using a Secure, Continually Updating, Web Source Processing Pipeline to Support the Real-Time Data Synthesis and Analysis of Scientific Literature: Development and Validation Study.

Background: The scale and quality of the global scientific response to the COVID-19 pandemic have unquestionably saved lives. However, the COVID-19 pandemic has also triggered an unprecedented "infodemic"; the velocity and volume of data production have overwhelmed many key stakeholders such as clinicians and policy makers, as they have been unable to process structured and unstructured data for evidence-based decision making. Solutions that aim to alleviate this data synthesis-related challenge are unable to capture heterogeneous web data in real time for the production of concomitant answers and are not based on the high-quality information in responses to a free-text query.

Material And Method: In this retrospective study we enrolled 30 paediatric patients previously diagnosed with UC, examined by abdominal US and colonoscopy within the same week. FC was also determined during the same week.

B cell-activating factor (BAFF) in children with inflammatory bowel disease.

Background: Assessing the inflammation is important in the follow-up of paediatric patients with inflammatory bowel disease (IBD). We aim to evaluate the value of B cell-activating factor (BAFF) in paediatric IBD as a potential biomarker for follow-up.

Method: We determined BAFF in serum and faeces and faecal calprotectin (CP) in 32 IBD children-16 Crohn's disease (CD) and 16 ulcerative colitis (UC).

Do ankle, hindfoot, and heel ultrasound findings predict the symptomatology and quality of life in rheumatoid arthritis patients?

To evaluate the ankle, hindfoot, and heel changes (determined by physical examination, ultrasound and baropodometry) in patients with rheumatoid arthritis, to compare the findings with healthy subjects, and to analyze if these findings are associated with ankle pain and could affect the quality of life. We enrolled 35 rheumatoid arthritis patients and 35 healthy controls, and evaluated their ankles (tibiotalar joints, tendons), hindfeet (talonavicular, subtalar joints) and heels using clinical examination, DAS28-CRP, RAPID3 for the evaluation of functional status, quality of life in rheumatoid arthritis questionnaire, ultrasound, and baropodometry. The ultrasound inter-observer agreement was good for the subtalar joint, and very good for the other structures.

Combining surface-enhanced Raman scattering (SERS) of saliva and two-dimensional shear wave elastography (2D-SWE) of the parotid glands in the diagnosis of Sjögren's syndrome.

In this study, we combine the molecular structural information gained by SERS of saliva samples with the morphological data given by two-dimensional shear wave elastography (2D-SWE) (SuperSonic Imagine, Aixplorer) of parotid glands in the case of n = 31 patients with Sjögren's syndrome (SjS) and n = 22 controls, with the aim to discriminate between the two groups. The overall classification accuracy yielded by a hybrid principal component analysis-linear discriminant analysis (PCA-LDA) model based on both SERS and elastography (81%) was superior to that yielded by SERS spectra alone (75%) and elastography data alone (71%). This preliminary study is the first report on the use of 2D-SWE of parotid glands for the diagnosis of SjS as well as the first to describe the diagnosis of SjS based on the SERS spectra of dried saliva samples, the results suggesting that the strategy of combining the two methods could improve the diagnosis of SjS.

Shear wave elastography as a new method to identify parotid lymphoma in primary Sjögren Syndrome patients: an observational study.

Parotid non-Hodgkin lymphoma (NHL) in primary Sjögren syndrome (pSS) has no specific biomarker for diagnosis. Salivary glands ultrasound (US) is largely used, but its contribution in detecting parotid NHL has not been established. The aim of our study was to determine the added value of bidimensional shear wave elastography (2D-SWE) in pSS diagnosis and to determine its accuracy in identifying parotid NHL.

The evaluation of oxidative stress in osteoarthritis.

Osteoarthritis (OA) is a whole joint disease driven by abnormal biomechanics and attendant cell-derived and tissue-derived factors. The disease is multifactorial and polygenic, and its progression is significantly related to oxidative stress and reactive oxygen species (ROS). Augmented ROS generation can cause the damage of structural biomolecules of the joint and, by acting as intracellular signaling component, ROS are associated with various inflammatory responses.

Reasons for discordances between ultrasonography and magnetic resonance imaging in the evaluation of the ankle, hindfoot and heel of the patients with rheumatoid arthritis.

Aim: To compare the ultrasonography (US) performance with magnetic resonance imaging (MRI) in identifying pathology in ankles, hindfeet and heels of rheumatoid arthritis (RA) patients and to evaluate the reasons for discordances between the two imaging methods.

Material And Methods: RA patients were enrolled and evaluated using the Clinical Disease Activity Index (CDAI) and the Disease Activity Score 28 with C-reactive Protein (DAS28-CRP). The ankle (tibiotalar joint, tendons), hindfoot (talonavicular, subtalar joints) and heel of the most symptomatic or dominant foot (for the asymptomatic patient)were evaluated by two pairs of examiners using US and contrast-enhanced MRI.

Multimodal ultrasound investigation (grey scale, Doppler and 2D-SWE) of salivary and lacrimal glands in healthy people and patients with diabetes mellitus and/or obesity, with or without sialosis.

Aim: To evaluate the ultrasound (US) modifications [grey scale, Doppler, 2D-share wave elastography (2D-SWE)] ofsalivary (parotid and submandibular) and lacrimal glands in healthy people and patients with diabetes mellitus and/or obesity, with or without sialosis.

Material And Methods: We evaluated 170 patients (1020 glands, 1700 grey scale and Doppler images), split in two groups (group 1- healthy people, group 2- obese and/or diabetes patients, with or without sialosis). For each patient we assessed the parotid, submandibular and lacrimal glands in grey scale US (echogenicity, homogeneity, glandular contour, posterior border, lymph nodes), color Doppler US and 2D-SWE.

SERS-based liquid biopsy of saliva and serum from patients with Sjögren's syndrome.

In this preliminary study, we employed surface-enhanced Raman scattering (SERS) of saliva and serum samples for diagnosing Sjogren's syndrome (SjS), a systemic autoimmune disease characterized by dryness of the mouth and eyes. The saliva and serum samples from n = 29 patients with SjS and n = 21 controls were deproteinized with methanol and then the SERS spectra were acquired using silver nanoparticles synthesized by reduction with hydroxylamine hydrochloride. In the case of both saliva and serum, the SERS spectra were dominated by similar bands attributed to purine metabolites such as uric acid, xanthine, and hypoxanthine.

The relevance of ultrasound examination of the foot and ankle in patients with rheumatoid arthritis - a review of the literature.

Rheumatoid arthritis (RA) is an inflammatory disease characterized by symmetrical involvement of the joints and tendons, especially of the hands and wrists, but also of the feet and ankles from the very beginning of the disease. For the patient, the foot and ankle involvement is equally important as the other joints, since it affects the functionality of the feet and the quality of life of the patients. It is already known that subclinical involvement of the ankles and feet occurs even in patients that are considered in clinical remission, thus they do not need for changes of therapy, but still might benefit from it.
