There is little evidence about the association of pre-existing hepatitis C infection (HCV) with outcomes in patients coronavirus disease 2019 (COVID-19).To assess prevalence history HCV among COVID-19 and to study relationship in-hospital mortality relation other predictors poor presence or absence induced acute liver injury.In a retrospective single-center design, 1193 were studied. Patients then classified into those without HCV, 50 (4.1%) 1157 (95.9%) respectively.Multivariate...
Wound contraction in humans has both positive and negative effects. It is beneficial to wound healing by narrowing the margins, but formation of undesirable scar contracture brings cosmetic even functional problems. The entire mechanism not clear yet, it at least considered that fibroblasts myofibroblasts are responsible for wounds. myofibroblast a cell possesses all morphologic biochemical characteristics fibroblast smooth muscle cell. Normally, appear initial processes generate contractile...
Antimicrobial peptides (AMPs) are promising therapeutics in the fight against multidrug-resistant bacteria. As a mimic of AMPs, peptoids with N-substituted glycine backbone have been utilized for antimicrobials resistance proteolytic degradation. known to kill bacteria by membrane disruption; however, nonspecific aggregation intracellular contents is also suggested as an important bactericidal mechanism. Here,structure-activity relationship (SAR) library indole side chain-containing...
Glucagon-like peptide-1 receptor agonists (GLP-1 RA) are effective in diabetes and obesity, reducing hyperglycemia by increasing insulin release delaying gastric emptying. However, they can cause gastroparesis, raising concerns about aspiration during procedures. Recent guidelines advise discontinuing GLP-1 RA before surgery to reduce the risk of pulmonary aspiration.
Traditional recommendation approaches do not consider the changes of user preferences according to context. As a result, these userpsilas overall preferences, although on items varies his/her However, in our context-aware approach, we take into account only but also context information. Our approach can be easily adopted for content-based and collaborative filtering based recommendations. To exploit raw information recommendation, abstract concept level. Moreover, by aggregating information,...
Monoclonal antibody therapy (MAT) is recommended in mild to moderate Coronavirus disease 2019 (COVID-19) patients who are at risk of progressing severe disease. Due limited data on its outcomes and the logistic challenges administering drug, MAT has not been widely used United States (US) despite emergency use authorization (EUA) approval by Food Drug Administration (FDA). We aim study predominantly from ethnic minority groups we experienced implementing infusion protocol an inner-city...
Cutaneous manifestations are interesting presentations of COVID-19 infection, but only a few cases have described the histological findings skin biopsy in these patients. We present case positive patient with morbilliform rash whose showed presence fibrin microthrombi within small vessels as main distinctive histologic feature.
Thyroid dysfunction has been reported to be an extrapulmonary symptom of COVID-19. It is important identify the tissue subset that expresses angiotensin-converting enzyme 2 (ACE2) and transmembrane protease serine (TMPRSS2), which are essential for host infection with severe acute respiratory syndrome coronavirus (SARS-CoV-2), in order understand viral pathogenesis COVID-19-related thyroid dysfunction. We investigated expression distribution ACE2- TMPRSS2-expressing cells gland. RT-PCR...
Right ventricular (RV) dysfunction in acute COVID-19 was reported to be associated with poor prognosis. We studied the association between parameters of RV and in-hospital mortality during surges caused by different SARS-CoV-2 variants.In a retrospective single-center study, we enrolled 648 consecutive patients hospitalized [66 (10 %) alpha variant surge, 433 (67 delta 149 (23 %), omicron surge]. Patients were from hospital an underreported population mostly African American Hispanic...
As large language models (LLMs) expand their sizes, conventional GPU-based LLM inference systems face memory bandwidth and capacity limitations. An accelerator using NAND flash storage has been proposed to overcome these challenges. However, this necessitates a significant expansion of channels ensure adequate for inference, subsequently escalating error correction code (ECC) costs. This paper examines the impact errors on accuracy explores possibility lightweight ECC by leveraging LLM's...
Road traffic injuries (RTIs) are the leading cause of mortality among children and adolescents. This study aimed to compare clinical characteristics identify factors associated with severe RTIs based on types road users adolescents RTIs.
Breast cancers metastasize most commonly to the bone, brain, liver, and lungs, but rarely gastrointestinal tract. Although metastatic breast carcinomas in stomach can be confused with primary gastric due their nonspecific presentation rare incidence, it is important differentiate two since treatment different. Clinical suspicion imperative for a prompt endoscopic evaluation definitive diagnosis that will lead appropriate treatment. Therefore, clinicians aware of possibility metastasis...
Background: Right ventricular (RV) dysfunction in acute COVID-19 was reported to be associated with poor prognosis. We studied the association between parameters of RV and in-hospital mortality during surges caused by different SARS-CoV-2 variants.Methods: In a retrospective single-center study, we enrolled 648 consecutive patients hospitalized [66 (10%) alpha variant surge, 433 (67%) delta 149 (23%), omicron surge]. Patients were followed for median 11 days which death occurred 155 (24%)...
Pseudoaneurysms occur when there is a partial disruption in the wall of blood vessel and can cause delayed rupture massive hemorrhage. Most pseudoaneurysms face form as result blunt, penetrating, or surgical trauma. As small diameter facial artery its deep protected location, proximal parts caused by blunt trauma are very rare has never been reported Korea. The authors report case posttraumatic pseudoaneurysm 45-year-old male, who was treated with percutaneous embolization hematoma evacuation.
This paper introduces a novel post-processing algorithm for low-density parity-check (LDPC) codes adequate NAND flash memory, to improve error correction capability of soft decision decoding by reducing strong effects in an efficient way. In this algorithm, it can detect variable nodes errors using incoming check-to-variable (c2v) messages and reduce magnitude channel reliability the avoid supplying large erroneous variable-to-check (v2c) check nodes. The proposed post processing with finite...
목적: 본 연구는 역방향(Everted) 실리콘 하이드로겔 렌즈 착용 후 각막 굴절력의 변화에 대하여 연구하였다. 방법: 변화를 알아보기 위해 corneal topographer(CT-1000, Shin-nippon Co., Japan)를 이용하여 주경선 굴절력과 각막난시를 측정하였고, 굴절이상도 변화는 자동굴절검사기(Natural vision-K 5001, 타각적 굴절검사를 실시하였다. 전과 1주일 후의 알아보았다. 결과: 결과 경도 근시에서 보다 효과적으로 굴절력을 교정할 수 있었고, 각막의 강주경선의 굴절력이 클수록, 각막난시가 많을수록 눌림이 많았다. 대상자의 73%가 1 D이하의 감소를 보였고, 17%가 굴절이상도가 증가하는 역효과가 나타났다. 굴절이상도의 감소는 크고 많을 때 효과적이었다. 결론: 역방향 렌즈에 의해 각막눌림이 야기될 있고, 이는 각막난시, 굴절이상도에 따라 정도의 차이가 발생하였다. 렌즈의 파라미터를 변경하기 힘든 점을 고려하여 적정한 선정이...
