BACKGROUND: Left-sided intracardiac thrombi are most commonly seen in conditions with decreased cardiac flow, such as myocardial infarction or atrial fibrillation. They can be propagated into the systemic circulation, leading to a cerebrovascular accident. Identification of thrombus-in-transit via point-of-care ultrasound (POCUS) has the potential to change patient management given its association with high patient morbidity and mortality. CASE REPORT: An intubated 60-year-old man was transferred to our emergency department for management of altered mental status and seizure-like activity...

The tricuspid regurgitation pressure gradient (TRPG) reflects the difference in pressure between the right ventricle and right atrium (ΔPRV-RA ). Its estimation by echocardiography correlates well with that obtained using right-heart catheterization. An elevated TRPG is an important marker for identifying right ventricular dysfunction in both the acute and chronic settings. However, in the "wide-open" variant of TR, the TRPG counterintuitively falls. Failure to recognize this potential pitfall and underlying pathophysiology can cause underestimation of the severity of right ventricular dysfunction...

PURPOSE: Panoramic ultrasound is one of the recently introduced ultrasound evaluation techniques. We herein examined the relationship between the cross-sectional area of the rectus femoris muscle on panoramic ultrasound and its volume based on the gold standard computed tomography (CT) evaluation. METHODS: This was a single-center prospective observational study. A panoramic ultrasound assessment of the cross-sectional area of the rectus femoris muscle and a simple CT evaluation of its volume were performed on days 1 and 7 of hospitalization...

BACKGROUND: Conjoined twins (CT), which used to be historically defined as "monstrous human" and previously so-called Siamese twins in the early eighteenth century, are one of the very rare congenital malformations with an uncertain etiology and complex yet remain inconclusively debatable regarding its pathophysiological mechanisms of fusion and fission theories. Among all types of CT, parasitic CT, especially the pygopagus sub-type, is exceedingly rarer. To the best of the authors' knowledge, no parasitic CT had been reported in Papua, and this is the first finding in South Papua...

BACKGROUND: The quadratus lumborum block (QLB) is an effective technique to provide analgesia for upper and lower abdominal surgeries. There are various approaches described in the literature, but the best approach is still to be explored. This study aims to compare the analgesic efficacy of three different approaches of QLBs. METHODS: Sixty-five patients, aged 18-70 years posted for elective laparoscopic abdominal surgery under general anesthesia were enrolled after taking written informed consent...

BACKGROUND: The frozen elephant trunk (FET) technique as a hybrid combining surgical and endovascular repair is an emerging concept to treat complex aortic dissection. Early experience showed technical feasibility and promising clinical outcomes. However, unsuspected complications still arise. CASE SUMMARY: A 25-year-old male presented to the emergency department with a 2-day history of chest pain. After exclusion of acute coronary syndrome, a computed tomography angiography (CTA) revealed Type A (DeBakey Type I) aortic dissection...

CoNb2 O6 is a model system for a spin-1/2 one-dimensional (1D) transverse-field Ising magnet (TFIM) with a rather low 3D Neel ordering temperature at T N = 2.95 K. We studied CoNb2 O6 using ultrasound measurements down to 0.3 K in transverse magnetic fields applied along the b direction. Upon entering the 3D ordered state, we observe pronounced anomalies in the transverse acoustic mode c 66 . In particular, from 1.3 to 1.5 K and around 4.7 T, this mode reveals an almost diverging softening, which is considerably reduced at lower and higher magnetic fields...

Diagnostic imaging is essential in modern trauma care for initial evaluation and identifying injuries requiring intervention. Deep learning (DL) has become mainstream in medical image analysis and has shown promising efficacy for classification, segmentation, and lesion detection. This narrative review provides the fundamental concepts for developing DL algorithms in trauma imaging and presents an overview of current progress in each modality. DL has been applied to detect free fluid on Focused Assessment with Sonography for Trauma (FAST), traumatic findings on chest and pelvic X-rays, and computed tomography (CT) scans, identify intracranial hemorrhage on head CT, detect vertebral fractures, and identify injuries to organs like the spleen, liver, and lungs on abdominal and chest CT...

Nanoemulsions are gaining interest in a variety of products as a means of integrating easily degradable bioactive compounds, preserving them from oxidation, and increasing their bioavailability. However, preparing stable emulsion compositions with the desired characteristics is a difficult task. The aim of this study was to encapsulate the Tinospora cordifolia aqueous extract (TCAE) into a water in oil (W/O) nanoemulsion and identify its critical process and formulation variables, like oil (27-29.4 mL), the surfactant concentration (0...

Despite the established safety and efficacy of midurethral slings (MUS), which are the current gold standard treatment for stress urinary incontinence (SUI), the potential for postoperative complications remains a significant concern for both healthcare professionals and patients. Meanwhile, sonography has emerged as a significant diagnostic tool in urogynecology, and one of the applications of this imaging modality may be the evaluation of complications arising from MUS procedures. This review, based on a comprehensive literature search, focuses on the use of pelvic floor ultrasound (US) in the context of MUS complications...

Surgical neuromodulation has witnessed significant progress in recent decades. Notably, deep brain stimulation (DBS), delivered precisely within therapeutic targets, has revolutionized the treatment of medication-refractory movement disorders and is now expanding for refractory psychiatric disorders, refractory epilepsy, and post-stroke motor recovery. In parallel, the advent of incisionless treatment with focused ultrasound ablation (FUSA) can offer patients life-changing symptomatic relief. Recent research has underscored the potential to further optimize DBS and FUSA outcomes by conceptualizing the therapeutic targets as critical nodes embedded within specific brain networks instead of strictly anatomical structures...

INTRODUCTION AND IMPORTANCE: Rectus sheath hematoma (RSH) is an uncommon but significant cause of acute abdominal pain in pregnancy, challenging in both diagnosis and treatment. It often arises from ruptured epigastric vessels and is associated with factors like anticoagulation therapy and previous abdominal surgery. Misdiagnosis, due to nonspecific symptoms, frequently leads to unnecessary surgeries, posing substantial risks to maternal and fetal health. CASE PRESENTATION: We present a case of a 32-year-old multiparous woman at 31 weeks of gestation, experiencing right-sided abdominal pain and irregular contractions...

Cardiac ultrasound (CUS), either focused cardiac ultrasound (FoCUS) or emergency echocardiography, is frequently used in cardiovascular (CV) emergencies. We assessed correlations and discrepancies between CUS, clinical diagnosis and the autopsy findings in early deceased patients with suspected CV emergencies. We retrospectively analysed clinical and autopsy data of 131 consecutive patients who died within 24 h of hospital admission. The type of CUS and its findings were analysed in relation to the clinical and autopsy diagnoses...

PURPOSE: Trauma, particularly extremity trauma, poses a considerable challenge in healthcare, especially among young adults. Given the severity of patient pain and the risks associated with excessive opioid use, managing acute pain in trauma centers is inherently complex. This study aims to investigate the application and benefits of ultrasound-guided nerve blocks for early pain management in patients with extremity trauma positioned supine. METHODS: A comprehensive literature review was conducted to assess the effectiveness and advantages of ultrasound-guided peripheral nerve blocks in the acute pain management of extremity trauma patients in the supine position...

OBJECTIVE: To examine the association between EIF and risk of preterm birth, chromosomal abnormalities, and cardiac abnormalities. DESIGN: A review across four databases to identify English language journal articles of EIF using a cohort study design...

OBJECTIVES: Central venous catheterization is used widely in critical pediatric patients. The authors sought to compare the success rate and safety of ultrasound-guided subclavian vein cannulation performed via infraclavicular and supraclavicular approaches. DESIGN: The authors compared the success rate of the first puncture and other information for cannulation in the children with congenital heart disease requiring central venous catheterization who were assigned randomly to the supraclavicular approach group (group A) or infraclavicular approach group (group B)...

OBJECTIVE: Involvement of the lower urinary tract is found in 0.2-2.5% of all deep infiltrating endometriosis (DIE)1 , 2 . The bladder is the most affected organ with a prevalence of up to 80% of cases3 . Patients with bladder endometriosis are often symptomatic (dysuria, hyperactive bladder, recurrent urinary tract infections and hematuria). Surgery is the gold standard treatment for this condition when medical therapy fails1 , 2 . Several studies have shown the feasibility, effectiveness, and safety of the laparoscopic approach4 but data about robotic-assisted approach are missing in literature...

Pyroptosis, a novel type of programmed cell death (PCD), which provides a feasible therapeutic option for the treatment of tumors. However, due to the hypermethylation of the promoter, the critical protein Gasdermin E (GSDME) is lacking in the majority of cancer cells, which cannot start the pyroptosis process and leads to dissatisfactory therapeutic effects. Additionally, the quick clearance, systemic side effects, and low concentration at the tumor site of conventional pyroptosis reagents restrict their use in clinical cancer therapy...

BACKGROUND: Adverse changes in muscle health (size and quality) are common in patients receiving extracorporeal membrane oxygenation (ECMO). Nutrition delivery may attenuate such changes, yet the relationship with muscle health remains poorly understood. This study explored the association between energy and protein delivery and changes in muscle health measured using ultrasound from baseline to day 10 and 20 in patients receiving ECMO. METHODS: A secondary analysis of data from a prospective study quantifying changes in muscle health using ultrasound in adults receiving ECMO was completed...
