Advances in drug delivery systems utilizing blood cells and their membrane-derived microvesicles.

The advancement of drug delivery systems (DDSs) in recent decades has demonstrated significant potential in enhancing the efficacy of pharmacological agents. Despite the approval of certain DDSs for clinical use, challenges such as rapid clearance from circulation, toxic accumulation in the body, and ineffective targeted delivery persist as obstacles to successful clinical application. Blood cell-based DDSs have emerged as a popular strategy for drug administration, offering enhanced biocompatibility, stability, and prolonged circulation.

Continuous debridement combined with short-term posaconazole therapy for cutaneous mucormycosis caused by infection secondary to acute myeloid leukemia: a case report.

Cutaneous mucormycosis is a rare fungal infection marked by skin abscesses, swelling, necrosis, dry ulcers, and eschars. Though less fatal compared to other mucormycosis forms, delayed diagnosis and treatment in immunocompromised patients can cause the infection to spread to vital organs, becoming life-threatening. We report a case of lower extremity cutaneous mucormycosis secondary to acute myeloid leukemia, successfully managed with sustained surgical debridement and short-term oral posaconazole.

The emerging role of extracellular vesicles and particles in prostate cancer diagnosis, and risk stratification.

Current approaches for prostate cancer (PCa) diagnosis and risk stratification require greater accuracy. Extracellular vesicles and particles (EVPs) containing diverse cargos from parent cells are released into the extracellular microenvironment and play a critical role in intercellular communication. Accumulating evidence demonstrates that EVPs are emerging as a promising focus for the exploration of cancer biomarkers and therapeutic targets.

The time-to-surgery interval and its effect on pathological response after neoadjuvant chemoimmunotherapy in non-small cell lung cancer: a retrospective cohort study.

Background: The time to surgery (TTS) after the completion of the final cycle of neoadjuvant chemoimmunotherapy in patients with non-small cell lung cancer (NSCLC) is inconsistent. Pathological complete response (pCR) and major pathological response (MPR) are associated with enhanced survival in those with NSCLC. The optimal TTS interval remains to be determined, some studies indicated that TTS ≤6 weeks has a vital role in NSCLC prognosis.

Effect of carbon black and silicon dioxide nanoparticle exposure on corona receptor ACE2 and TMPRSS2 expression in the ocular surface.

The Coronavirus disease 2019 (COVID-19) pandemic has led to a global health crisis, including ocular symptoms, primarily targeting the Angiotensin-Converting Enzyme 2 (ACE2) receptor. PM2.5 air pollution may increase infection risk by altering ACE2 expression.

Cytoglobin augments ferroptosis through autophagic degradation of ferritin in colorectal cancer cells.

Autophagy has gained importance in the context of ferroptosis. Nevertheless, a deeper understanding of the regulatory mechanism governing autophagy-dependent ferroptosis is necessary. Cytoglobin (CYGB), a member of the globin family, exhibits antifibrotic effects, regulates cellular reactive oxygen species, and stimulates tumor inhibition.

Ultrasensitive SERS-based detection of prostate cancer exosome using CuO-CuO@Ag composite nanowires.

Exosome is a recently emerging cancer-associated biomarker for early diagnostic and prognostic owing to their noninvasive, intrinsic stability, and representativeness of primitive cell state. However, the development of convenient and quantitative methods for exosome analysis remains technically challenging. Here, we proposed a cost-effective assay for the direct capture and rapid monitoring of exosomes utilizing the multifunctional surface enhanced Raman scattering (SERS) substrate, which consisted of CuO-CuO nanowires prepared by a simple thermo-oxidative growth method and subsequently sputtered with Ag NPs.

The decreased serum levels of interleukin-38 in patients with gout and its clinical significance.

Background: Interleukin (IL)-38 is a newly discovered anti-inflammatory cytokine. However, its concentration and clinical significance in patients with gout remain unclear. This study aimed to investigate the levels of IL-38 in patients with gout and evaluate their clinical significance.

Biological functions and molecular mechanisms of exosome-derived circular RNAs and their clinical implications in digestive malignancies: the vintage in the bottle.

Background: Circular RNAs (circRNAs) are identified as a novel family of endogenous RNA molecules through 'back-splicing' and covalently linked at the 5' and 3' ends. Emerging researches have demonstrated circRNAs are stable and abundant in exosomes called exosomal circRNAs (exo-circRNA).

Materials And Methods: We searched recent studies and references to summary the research progress of exosomal circRNA.

The impact of sleep disturbances on treatment efficacy and prognosis in patients with depressive and anxiety disorders.

Introduction: Little was known about the relationship between sleep disturbances and depressive and anxiety disorders, as well as the efficacy of treatment regimens.

Methods: During 2021 to 2023, a total of 417 participants were screened by Hamilton Depression Rating Scale (HAMD-17) and Hamilton Anxiety Rating Scale (HAMA-14) for psychological status, and Pittsburgh sleep quality index (PSQI) assessment. 409 participants were finally enrolled, of which 188 (45.

Elevated non-HDL-C to HDL-C ratio as a marker for NAFLD and liver fibrosis risk: a cross-sectional analysis.

Background: Dyslipidemia is a known independent risk factor for Nonalcoholic fatty liver disease (NAFLD). However, the relationship between NAFLD and the serum non-high-density lipoprotein cholesterol (non-HDL-C) to high-density lipoprotein cholesterol (HDL-C) ratio remains unclear. This study examined the association between the non-HDL-C to HDL-C ratio and NAFLD prevalence, including liver steatosis and fibrosis levels in the population.

Case report: HPV related pelvic retroperitoneal squamous cell cancer of unknown primary presenting as ovary neoplasm.

Introduction: Retroperitoneal tumors (RPTs) of the pelvis are rare and often present asymptomatically. We report a rare case of human papillomavirus (HPV)-related primary retroperitoneal squamous cell carcinoma (PRSCC) that was preoperatively misdiagnosed as adnexal cancer.

Case Presentation: A menopausal 59-year-old woman presented with right leg pain persisting for two months.

Subcutaneous adipose tissue measured by computed tomography could be an independent predictor for early outcomes of patients with severe COVID-19.

Background: Patients with severe Coronavirus Disease 2019 (COVID-19) can experience protein loss due to the inflammatory response and energy consumption, impairing immune function. The presence of excessive visceral and heart fat leads to chronic long-term inflammation that can adversely affect immune function and, thus, outcomes for these patients. We aimed to explore the roles of prognostic nutrition index (PNI) and quantitative fat assessment based on computed tomography (CT) scans in predicting the outcomes of patients with severe COVID-19.

Superior performance of a center-point AI model over VFLDNet in automated cobb angle estimation for scoliosis assessment.

Purpose: Aims to establish the superiority of our proposed model over the state-of-the-art vertebra-focused landmark detection network (VFLDNet) in automating Cobb angle estimation from spinal radiographs.

Methods: Utilizing a private dataset for external validation, we compared the performance of our center-point detection-based vertebra localization and tilt estimation network (VLTENet) with the key-point detection-based VFLDNet. Both models' Cobb angle predictions were rigorously evaluated against manual consensus score using metrics such as mean absolute error (MAE), correlation coefficient, intraclass correlation coefficient (ICC), Fleiss' kappa, Bland-Altman analysis, and classification metrics [sensitivity (SN), specificity, accuracy] focusing on major curve estimation and scoliosis severity classification.
