Quantifying pleural effusion change at chest CT is important for evaluating disease severity and treatment response. The purpose of this study was to assess the accuracy of artificial intelligence (AI)-based volume quantification of pleural effusion change on CT images, using the volume of drained fluid as the reference standard. Seventy-nine participants (mean age ± SD, 65 years ± 13; 47 male) undergoing thoracentesis were prospectively enrolled from October 2021 to September 2023.

Graph theory has been widely used to quantitatively analyze complex networks of molecules, materials, and cells. Analyzing the dynamic complex structure of extracellular matrix can predict cell-material interactions but has not yet been demonstrated. In this study, graph theory-based mathematical modeling of RGD ligand graph inter-relation is demonstrated by differentially cutting off RGD-to-RGD interlinkages with flexibly conjugated magnetic nanobars (MNBs) with tunable aspect ratio.

The native extracellular matrix is continuously remodeled to form complex interconnected network structures that reversibly regulate stem cell behaviors. Both regulation and understanding of its intricate dynamicity can help to modulate numerous cell behaviors. However, neither of these has yet been achieved due to the lack of designing and modeling such complex structures with dynamic controllability.

Background: Adverse impacts of the COVID-19 pandemic on mental health have been well-documented, but only a few studies have characterized distinct trajectories of anxiety over time. Further, whether specific emotion regulation and coping efforts to manage pandemic distress predict these distinct trajectories remains unexamined.

Aims: The study characterized anxiety trajectories across the first year of the pandemic and identified emotion regulation and coping strategies that predict these classes of anxiety trajectories.

Background: Transoral robotic surgery (TORS) performed after neoadjuvant chemotherapy (NAC) is a promising treatment for advanced-stage oropharyngeal carcinoma (OPSCC) able to reduce the adjuvant therapy administration rate.

Methods: A retrospective bi-centric study was conducted to analyze NAC + TORS versus upfront TORS patients. A 1:1 propensity score matching was used to compare the two groups.

Cancer treatment requires precise tumor-specific targeting at specific sites that allows for high-resolution diagnostic imaging and long-term patient-tailorable cancer therapy; while, minimizing side effects largely arising from non-targetability. This can be realized by harnessing exogenous remote stimuli, such as tissue-penetrative ultrasound, magnetic field, light, and radiation, that enable local activation for cancer imaging and therapy in deep tumors. A myriad of nanomedicines can be efficiently activated when the energy of such remote stimuli can be transformed into another type of energy.

Purpose: Clinical implications of neoadjuvant immunotherapy in patients with locally advanced but resectable head and neck squamous cell carcinoma (HNSCC) remain largely unexplored.

Patients And Methods: Patients with resectable HNSCC were randomized to receive a single dose of preoperative durvalumab (D) with or without tremelimumab (T) before resection, followed by postoperative (chemo)radiotherapy based on multidisciplinary discretion and 1-year D treatment. Artificial intelligence (AI)-powered spatial distribution analysis of tumor-infiltrating lymphocytes and high-dimensional profiling of circulating immune cells tracked dynamic intratumoral and systemic immune responses.

Extracellular matrix (ECM) undergoes dynamic inflation that dynamically changes ligand nanospacing but has not been explored. Here we utilize ECM-mimicking photocontrolled supramolecular ligand-tunable Azo self-assembly composed of azobenzene derivatives (Azo) stacked via cation-π interactions and stabilized with RGD ligand-bearing poly(acrylic acid). Near-infrared-upconverted-ultraviolet light induces -Azo-mediated inflation that suppresses cation-π interactions, thereby inflating liganded self-assembly.

Gene expression analysis enhances proper cancer subtyping, a better understanding of the molecular characteristics of cancer, and strategies for precision medicine. However, salivary gland cancer (SGC) subtyping remains largely unexplored because of its rarity and diverse histopathological and immunological characteristics. This study aimed to determine whether the histological origin and immunological characteristics of SGC subtypes are intrinsic tumor immunity factors.

Objective: To investigate the potential of deep learning for automatically delineating (segmenting) laryngeal cancer superficial extent on endoscopic images and videos.

Methods: A retrospective study was conducted extracting and annotating white light (WL) and Narrow-Band Imaging (NBI) frames to train a segmentation model (SegMENT-Plus). Two external datasets were used for validation.

Objectives: Since the onset of COVID-19 pandemic, additional risk factors affecting family caregivers' mental health have arisen. Therefore, personal stress coping strategies and family dynamics became important factors in reducing the impact of the pandemic on family caregivers' mental health. The present research aimed to estimate the association between COVID-19 stressors and family caregiving burden.

Background: Even when education and the use of safety equipment are emphasized, nurses frequently experience needlestick injuries. Understanding the risk situations and coping mechanisms for needlestick injuries experienced by nurses facilitates their prevention.

Objectives: We aimed to explore and describe the phenomenon of needlestick injuries through the research questions: (1) What causes nurses to suffer from needlestick injuries? (2) How to cope after a needlestick injury? and (3) What are the recommendations for needlestick injury prevention?

Methods: This qualitative descriptive study involved focus group interviews with 31 direct care nurses in 6 groups who had experienced needlestick injuries while working in different acute care hospitals across 3 regions in South Korea.

Unlabelled: A novel reversible monoamine oxidase B inhibitor, KDS2010, has been developed as a therapeutic candidate for neurodegenerative diseases. This study investigated its potential toxicity in non-human primates before human clinical trials. Daily KDS2010 doses (25, 50, or 100 mg/kg) were orally administered to cynomolgus monkeys (1 animal/sex/group, 4 males and 4 females) for 2 weeks to determine the dose range.

Unlabelled: Global meaning systems help people make sense of their experiences, but suffering can violate global meaning and create distress. One type of potential violation is conflict between one's experience of suffering and one's deeply-held beliefs about God as loving, powerful, and just. The problem of theodicy-why an all-powerful and all-loving God would allow suffering-has long been an important theological and philosophical concern, but little is known about how theodicy plays out psychologically for religious individuals facing serious life difficulties.

Objective: Da Vinci single port (SP) has been recently approved for transoral robotic surgery (TORS). Its characteristics make it particularly feasible for laryngeal and hypopharyngeal surgery. We report our experience comparing intra- and postoperative outcomes, technical advantages, and shortcomings of transoral laryngeal and hypopharyngeal resections performed with the da Vinci SP and the da Vinci Si/Xi systems.

Article Synopsis
  • Thrombocytopenia is a condition characterized by low blood platelet levels, increasing the risk of bleeding, and can be caused by reduced platelet production or immune system issues.
  • The study involved injecting three different antisense oligonucleotide (ASO) substances into monkeys over 12 weeks, categorizing them into groups based on the presence or absence of thrombocytopenia.
  • Whole genome sequencing was conducted on liver tissues from the monkeys to identify genetic variations that influence thrombocytopenia and the individual response to drugs.

Introduction: Characterizing the tumor microenvironment (TME) and immune landscape of cancer has been a promising step towards discovering new therapeutic biomarkers and guiding precision medicine; however, its application in mucoepidermoid carcinoma (MEC) has been sparse. Here, we conducted a comprehensive study to understand the properties of the TME and immune profiles of MEC.

Method: 20 patients with MEC were collected from Yonsei Head and Neck Cancer Centre, Yonsei University, South Korea.
