Portal venous gas is a rare finding in adults and is typically associated with underlying intestinal ischemia. Portal venous gas can be detected by a bedside point of care ultrasound (POCUS) examination in adult patients in critical care units (CCU). Findings include echogenic bubbles flowing centrifugally throughout the portal venous system.

We present the case of a 73-year-old female with advanced ischemic cardiomyopathy and cardiorenal syndrome who was managed in the CCU. She developed vague abdominal pain and respiratory depression requiring intubation and dialysis during her course of treatment in the CCU. Her findings were consistent with portal venous gas upon POCUS, prompting computed tomography of her abdomen and surgical consultation. She was ultimately found to have nonobstructive mesenteric ischemia.

PVG is an ominous radiological sign and reflects intestinal ischemia in up to 72% of cases. Acute mesenteric ischemia of the small bowel could be due to occlusive or nonocclusive obstruction of the arterial blood supply or obstruction of venous outflow. Nonocclusive obstruction accounts for 5% to 15% of patients with acute mesenteric ischemia.

With the increasing use of POCUS, critical care physicians should be aware of findings consistent with portal venous gas as a bedside tool for directing the treating physician toward an ominous diagnosis in patients with shock.

Meningoceles are defined as herniation of the meninges through a skull base defect. If brain tissue is herniated as well, then it is called meningoencephalocele. The most common locations of meningoceles are the cribriform plate and the lateral recess of the sphenoid sinus, with the most common presentation being CSF leakage. We present a case of temporal lobe meningocele that herniated through a defect in the greater wing of the sphenoid bone to the pterygoid fossa and that was diagnosed incidentally while evaluating the patient for seizures.

Case report and literature review.

The endonasal endoscopic approach is a suitable minimally invasive approach for the management of pterygoid fossa lesions, including meningoceles. In this case, the patient had epilepsy with the surgery resulting in the resolution of the seizures.

In this work, gold nanoparticles capped with Tween 20 were used for purification and microextraction of the main free thiols (cysteine, homocysteine, glutathione and methionine) in saliva based on Au-S bond formation. Ultrasound further sped up the releasing of the target analytes, and the releasing time needed was only 10 min, and the required sample volume was only 40 µL. The desorption solution could be directly injected for electrophoretic analysis without derivatization, and field-amplified sample stacking of electrophoretic online enrichment technology further improved the detection sensitivity. The synergistic enrichment effect made the enrichment factors of four analytes reach 1119-2067 times. This developed method was applied for the analyses of saliva samples of healthy volunteers. Acceptable sensitivity (LODs 0.15-1.5 ng mL-1) and recoveries (97.6-116%) were obtained in the saliva sample matrix. This proposed method provides an alternative for the sensitive detection of low-molecular-weight thiols in noninvasive body fluids, which has potential application prospect in the preliminary noninvasive diagnosis of diabetes, cardiovascular diseases, etc.Pre-alloyed CoCrFeMnNi high-entropy alloy (HEA) powders were prepared by gas atomization and consequently hot pressing sintered (HPS) at 1100 °C for 2 h for fabrication bulk materials. Sintered equiatomic CoCrFeMnNi HEA exhibited a homogeneous FCC structured single-phase solid solution and equiaxed grains with an average size of ∼16 μm. Analyses using TEM showed that sheet-like metastable structures with a size of ∼55 to 160 nm were formed in the sintered bulks. The nano-sized metastable structures were inherited from the gas atomized CoCrFeMnNi powders with nano-sized crystallites formed during the rapid solidification process. The room temperature yield and ultimate tensile strength of sintered HEA reached 358 and 778 MPa, respectively, and the alloy kept excellent plasticity of ∼28 %. Investigations of the deformation substructures at specific strain levels with EBSD revealed the sintered CoCrFeMnNi HEA kept FCC structured single phase and the main deformation mechanism was dislocation slip. The strengthening mechanism can be attributed to the combination effects of grain refinement and the presence of nano-sized metastable structures.

Patients in methadone maintenance treatment (MMT) with problem gambling (PG) experience worse psychosocial outcomes than their non-PG counterparts. Raptinal price Interventions targeting PG in MMT may enhance psychosocial functioning beyond gambling reduction and abstinence. The present study was a secondary data analysis that examined the trajectories of non-gambling outcomes of three brief PG interventions (i.e., brief psychoeducation, brief advice, motivational enhancement therapy plus cognitive-behavioral therapy [MET+CBT]) among MMT patients.

Participants (N=109) were engaged in substance use disorder treatment, met criteria for PG, and had a current or lifetime history of MMT. Latent growth curve models examined outcome trajectories of psychiatric, medical, legal, employment, and social problems, as well as psychological distress and quality of life. Follow-up analyses examined clinically significant change.

MET+CBT patients reported lower medical problems at baseline and over time than the brief interventions. There was no evidence of differences between interventions on the other outcomes.
