Cancer Stage Geospatial Analysis to Optimize Educational Activities in Pediatric Oncology and Hematology: A Retrospective Cohort Study.

Enhancing therapy outcomes in pediatric oncology and hematology relies on robust epidemiological surveillance. This study aimed to estimate cancer stage-related survival in pediatric patients with lymphoma and solid tumors by assessing changes over time and identifying spatial clustering of patients diagnosed at advanced stages. This retrospective observational cohort study included pediatric cancer patients treated in a single Greater Poland center, constituting 9% of Polish children from 2004 to 2017. The incidence, cancer stage, and patient coordinates were analyzed. The follow-up period ranged from 5 to 18years. Survival differences across tumor stages were evaluated using Kaplan‒Meier curves, log-rank tests, and trend analysis. Geographical analysis was performed with Kulldorff's scan statistics and the Bernoulli model. Among 1094 diagnosed patients, 511 with lymphoma and solid tumors were eligible. There was a decreasing trend in advanced-stage diagnoses (p = 0.0001), with a nearly twofold increase in low-stage diagnoses (OR = 1.98 [1.22; 3.24], p = 0.0061) from 2009-2011 to 2015-2017. Hazard ratios for neuroblastoma and sarcoma patients were more than fourfold greater, while survival differences were not significant for patients with nephroblastoma, germ cell tumors, or lymphoma. This study shows cancer stage-related survival dynamics. A substantial decrease in advanced-stage diagnoses over time emphasizes improved early detection. Geographical analysis pinpointed clusters with prevalent late-stage diagnoses, offering a practical tool for targeted educational interventions. The study underscores the pivotal impact of cancer stage on survival outcomes, emphasizing the need for ongoing surveillance and tailored interventions to further optimize pediatric oncology and hematology care.

High Alt Med Biol. 00:00-00, 2024. Background: Discordant results have been previously reported regarding the impact of high-altitude (HA) exposure on coagulation. We aimed to investigate changes in coagulation parameters in lowlanders exposed to HA for 14 days using a combination of dynamic coagulation assays and conventional in vitro tests. Material and Methods: We assessed coagulation in 10 lowlanders using whole-blood rotational thromboelastometry (ROTEM), thrombin generation assay (TGA) on poor-platelet plasma, and conventional coagulation tests. Tests were performed at low altitude (LA, 210 m) and at the end of a 14-day sojourn at HA, including passive ascents to 3,800 m for 6 days and then to 5,100 m for 8 days. Results: Conventional tests revealed significant changes in coagulation factors and inhibitors after HA exposure, although these changes remained within normal ranges. ROTEM assays demonstrated a delayed clot initiation in EXTEM/FIBTEM, without any alteration in clot firmness, in HA versus LA (p < 0.01). TGA changes showed an increase in time to peak (p < 0.01), a decrease in endogenous thrombin potential (p < 0.05), and a decrease in thrombin peak (p < 0.001). Conclusions: We found no evidence of hypercoagulability in lowlanders after a 14-day sojourn at HA. In contrast, dynamic coagulation assays (ROTEM and TGA) revealed a hypocoagulable pattern.

Overproduction of Cucurbitadienol through Modular Metabolic Engineering and Fermentation Optimization in Saccharomyces cerevisiae.

Cucurbitadienol is a key intermediate in the biosynthesis of cucurbitane-type compounds and serves as a precursor for mogrosides, cucurbitacins, and other valuable natural products of potential biological and food importance. However, microbial fermentation for cucurbitadienol production remains inefficient, limiting its potential for further industrial application. This study achieved the efficient synthesis of cucurbitadienol through a multimodular strategy. First, an N-degron tag was used to direct metabolic flux toward cucurbitadienol synthesis without compromising cell growth. Second, enzyme engineering strategies were employed to improve the utilization efficiency of intermediate metabolites. Finally, to increase precursor availability, the transcription factor UPC2-1 was introduced, which upregulated the expression of ERGs in the pre-squalene pathway. After eliminating nitrogen supplementation and optimizing fermentation conditions, cucurbitadienol accumulation in the 5 L bioreactor increased to 6.1 g/L, representing the highest titer reported to date. These findings provide a solid foundation for the industrial-scale production of cucurbitadienol and its derivatives.

CAR-based cell therapies for systemic lupus erythematosus.

The remarkable efficacy of chimeric antigen receptor (CAR) T cell therapy in hematological malignancies has provided a solid basis for the therapeutic concept, wherein specific pathogenic cell populations can be eradicated by means of targeted recognition. During the past few years, CAR-based cell therapies have been extensively investigated in preclinical and clinical research across various non-tumor diseases, with particular emphasis in the treatment of autoimmune diseases (ADs), yielding significant advancements. The recent deployment of CD19-directed CAR T cells has induced long-lasting, drug-free remission in patients with systemic lupus erythematosus (SLE) and other systemic AD, alongside a more profound immune reconstruction of B cell repertoire compared with conventional immunosuppressive agents and B cell-targeting biologics. Despite the initial success achieved by CAR T cell therapy, it is critical to acknowledge the divergences in its application between cancer and AD. Through examining recent clinical studies and ongoing research, we highlight the transformative potential of this therapeutic approach in the treatment of SLE, while also addressing the challenges and future directions necessary to enhance the long-term efficacy and safety of CAR-based cell therapies in clinical practice.

Synthesis of Polymers via Cancer Cell Metabolism-Mediated Controlled Radical Polymerization and Application in Engineering of Cell Surface.

In this study, we present a novel chemical biology strategy that leverages the reductive metabolic pathways of cancer cells to develop a new approach for synthesizing polymers in nonstrictly anaerobic conditions. This method utilizes the reductive metabolism of cancer cells to reduce Cu(II) to Cu(I), enabling Cu(I)-catalyzed controlled radical polymerization with poly(ethylene glycol) methyl ether methacrylate (MAPEGOMe) monomer, producing polymers with low dispersity (1.28-1.38). Furthermore, we found that this method could use MAPEGOMe as a monomer to in situ form a polymer layer on the initiator-modified cell surface, achieving a cell surface engineering modification. This study reveals the broad application value and potential of cancer cell metabolism-mediated controlled radical polymerization in the fields of chemical biology and polymer science.

Decision-making for wāhine Māori facing breast cancer surgery: a qualitative study

ABSTRACT Wāhine Māori (women/females) are disproportionally affected by breast cancer in Aotearoa New Zealand. Following a breast cancer diagnosis, wāhine must make important surgical decisions while navigating a Westernised health system that can be dismissive of Māori views of health and tikanga (customary practices). We investigated the decision-making process of wāhine who had undergone surgery for breast cancer within the preceding 12 months. Fifteen wāhine shared their perspectives on surgery, shared decision-making and information provided prior to surgery. Thematic analysis revealed that fear was a primary influence on decision -making, but this emotion could be mitigated by a good quality patient-clinician relationship fostered by the shared decision-making process. In particular, whakawhanaungatanga (establishing connection and relationships) was an essential basis for shared decision-making. Shared decision-making, in turn, enabled tino rangatiratanga (self-determination) and provided support during the difficult decision-making period. Multi-modal presentation of medical information, with inclusion of Te Reo Māori is relevant to many wāhine and could offer more equitable access to diagnostic information. These findings raise awareness of the importance of recognising tikanga, in particular, whakawhanaungatanga for wāhine Māori diagnosed with breast cancer.

Access to Primary Care Telemedicine and Visit Characterization in a Pediatric, Low-Income, Primarily Latino Population: Retrospective Study.

Since the COVID-19 pandemic, telemedicine has been widely integrated into primary care pediatrics. While initial studies showed some concern for disparities in telemedicine use, telemedicine uptake for pediatric patients in a low-income, primarily Latino community over a sustained period has yet to be described. We aimed to assess the relationship between demographics, patient portal activation, and telemedicine visits, as well as characterize diagnoses addressed in telemedicine, in a low-income, primarily Latino population over time. A multidisciplinary team conducted outreach for telemedicine and patient portal activation with the adoption of a new electronic health record. Data were collected on all in-person and telemedicine visits from February 2020 through April 2021 for 4 community-based pediatric practices. The outcomes included patient portal activation, telemedicine use, and reason for telemedicine visits. Bivariate tests and multivariate regression analyses were conducted to assess the independent effects of demographics on the likelihood of portal activation and having a telemedicine visit. Telemedicine diagnoses were categorized, and subanalyses were conducted to explore variations by age and month. There were 12,377 unique patients and 7127 telemedicine visits. Latino patients made up 83.4% (n=8959) of the population. Nearly all patients (n=10,830, 87.5%) had an activated portal, and 33.8% (n=4169) had at least 1 telemedicine visit. Portal activation decreased with age >2 years (2-4 years: adjusted odds ratio [aOR] 0.62, 95% CI 0.51-0.76; 5-11 years: aOR 0.28, 95% CI 0.23-0.32; 12-14 years: aOR 0.29, 95% CI 0.23-0.35; and 15-17 years: aOR 0.46, 95% CI 0.36-0.58). Spanish-speaking (aOR 0.52, 95% CI 0.45-0.59) and non-Latino patients (aOR 0.64, 95% CI 0.54-0.76) had decreased odds of activation and having a telemedicine visit (aOR 0.81, 95% CI 0.74-0.89 and aOR 0.71, 95% CI 0.62-0.81, respectively). The top 5 diagnostic categories for telemedicine were infectious disease (n=1749, 26.1%), dermatology (n=1287, 19.5%), gastrointestinal (n=771, 11.7%), well and follow-up care (n=459, 7%), and other specialty-related care (n=415, 6.3%). Infectious disease showed the most variation over time. Age-based patterns included a decrease in the proportion of infectious disease diagnoses by increasing age group and a higher proportion of well and follow-up care in older ages. Additional telemedicine diagnoses included common infant concerns for patients younger than 2 years of age; pulmonary, asthma, and allergy concerns for toddler or school-age children; behavioral health concerns for younger adolescents; and genitourinary and gynecologic concerns for older adolescents. The high engagement across demographics suggests feasibility and interest in telemedicine in this low-income, primarily Latino population, which may be attributable to the strength of outreach. Language-based disparities were still present. Telemedicine was used for a wide range of diagnoses. As telemedicine remains a vital component of pediatric health care, targeted interventions may enhance engagement to serve diverse pediatric patient populations.

Functionalized Multichannel Fluorescence-Encoded Nanosystem on Erythrocyte-Coated Nanoparticles for Precise Cancer Subtype Discrimination.

Rapid and precise cancer subtype discrimination is essential for personalized oncology. Conventional diagnostic methods often lack sufficient accuracy and speed. Here, we introduce a multichannel fluorescence-encoded nanosystem based on erythrocyte-coated polydopamine nanoparticles (PDA@EM), functionalized with multiple resurfaced fluorescent proteins. The fluorescence of these proteins is initially quenched by PDA@EM and restored upon cell addition. This multichannel fluorescence-encoded nanosystem enables highly sensitive "turn-on" fluorescence profiling of cancer cells within 30 min, achieving 100% accuracy in distinguishing various proteins and classifying a wide range of cancer cell lines, including subtypes of oral squamous cell carcinoma (OSCC). Notably, it offers rapid, label-free diagnostics of OSCC malignancy from clinical samples postsurgery. This capability was validated through histopathological and proteomic analyses, which identified protein signatures associated with tumor progression and immune suppression. Overall, our multichannel nanosensor represents an advanced molecular diagnostics platform, paving the way for personalized cancer treatment in clinical oncology.

Temporal Effects of Hypoxia Exposure at High Altitudes on Compensatory Brain Function: Evidence from Functional Connectivity of Resting-State EEG Brain Networks.

Ren, Hong, Xi-Yue Yang, Rui Su, HaiLin Ma, and Hao Li. Temporal Effects of Hypoxia Exposure at High Altitudes on Compensatory Brain Function: Evidence from Functional Connectivity of Resting-State EEG Brain Networks. High Alt Med Biol. 00:00-00, 2024. Background: The aim of this study was to investigate the effects of prolonged exposure to hypobaric hypoxia at high altitude on changes in brain function measured by electroencephalography (EEG), focusing specifically on the resting-state brain network functional connectivity and compensatory adaptations in brain function among individuals with varying durations of high altitude residency. Methods: In study I, 64 participants were divided into high-altitude group (HG) and low-altitude group (LG). Ninety-six long-term migrants residing at an altitude of 3,650 m were recruited for studyII and categorized into three groups based on their duration of stay at high altitude: group A (1-2 years), group B (8-10 years), and group C (18-20 years). Resting-state EEG data were collected from each participant, and functional connectivity analysis was conducted using Phase Locking Value. Results: Study I showed that participants with HG had stronger functional connectivity in the occipital lobe than those with LG (p < 0.05). The study II findings indicate that there were significant differences in functional connectivity strength among the frontal and occipital lobes in groups A, B, and C across the α, β, δ, and θ frequency bands. Specifically, the functional connectivity strength of the frontal lobe was significantly higher in group A compared with group B, and in group B compared with group C (p < 0.05). Additionally, the functional connectivity of the occipital lobe was significantly higher in group C compared with group B, and in group B compared with group A (p < 0.05). Conclusions: The consistent results of the whole frequency band suggest that the individual's occipital lobe function is enhanced to compensate for the damage of frontal lobe function, so as to better adapt to the extreme environment at high altitude.

Effect of the COVID-19 Pandemic on the Management of Breast Cancer Patients

Background: The COVID-19 pandemic has significantly affected breast cancer patients by causing delays in diagnosis and treatment processes. This study aims to investigate the effects of the pandemic on the treatment process and short-term outcomes of breast cancer patients. Methods: This retrospective, cross-sectional, single-center study included 414 patients who underwent surgery for breast cancer at the Inonu University General Surgery Clinic between March 2018 and June 2021. The patients were divided into two groups: pre-pandemic (Pre-COVID-19; n = 240) and pandemic (COVID-19 Era; n = 174) periods. The groups were compared in terms of demographic, clinical, and histopathological variables. Results: During the pandemic period, the use of neoadjuvant therapy (from 21.3% to 34.5%) and preoperative PET-CT imaging (from 80.4% to 90.8%) rates increased, while breast-conserving surgery (from 27.9% to 19.0%) and the presence of comorbid diseases (from 45.0% to 29.9%) decreased significantly. While there was no significant difference between the groups in terms of the time from diagnosis to surgery (25 vs. 28.5 days, p = 0.121), the time to report the pathology result after surgery decreased during the pandemic period (28 vs. 23 days, p &lt; 0.001). There was no significant difference between the groups in terms of immunohistochemical (ER, PR, Ki-67, E-cadherin, and c-erbB2), histopathological (lymphovascular invasion, perineural invasion, comedo necrosis, modified Bloom–Richardson grade, and TNM classification), and clinical (recurrence, metastasis, and axillary lymph node metastasis) features of the tumor. The mortality rate in the Pre-COVID-19 group (7.1%) was significantly higher than in the COVID-19 Era group (2.3%) (p = 0.049). Finally, in terms of the survival analysis, a statistically significant difference was found between the Pre-COVID-19 and COVID-19 Era groups in terms of the mean follow-up duration of the patients (p = 0.044). Conclusions: The study results show that the use of neoadjuvant therapy and radical surgery preference increased in breast cancer treatment during the pandemic period, but there was no significant change in tumor biology and histopathological features. Breast-conserving surgery rates, comorbidity rates, and pathology reporting times were significantly shortened. Long-term follow-up periods of 3 and 5 years are needed to see the impact of the pandemic on breast cancer patients.

Integrating Innovation and Virtue: Strategic Responses of Private Organizations Amidst Environmental Shocks

Environmental shocks like the COVID-19 pandemic force private service sector organizations to innovate while upholding virtuous practices. How do these organizations balance innovating their service with maintaining their core values during crises? Through an inductive, longitudinal case study of Sri Sathya Sai Sanjeevani Hospital (SSSSH), a private healthcare organization offering free paediatric cardiac care in India, we explore how it responded to the pandemic. Drawing from archival data and field observations, we develop a process model demonstrating how SSSSH navigated the crisis by combining external innovation pressures with an internal culture of resilience, empathy and integrity. The model reveals an iterative process where external shocks catalyze internal virtuous responses, leading to adaptive innovations such as telemedicine and strategic resource utilization in resource-constrained environments. This dynamic interplay between external pressures and internal virtues challenges the traditional linear views of crisis management. It suggests that virtuousness embedded in an organization’s culture enables sustained innovation during extreme challenges. Our findings contribute to research on organizational responses to crises and the role of internal virtues in shaping adaptive strategies. This study advances the understanding of how private healthcare institutions can transform external challenges into opportunities while maintaining high standards of care and ethical responsibility.

A Comparative Study of Soft Tissue Release and Stretching in Treating Axillary Web Syndrome After Breast Cancer Surgery

Background: Axillary Web Syndrome (AWS) is increasingly recognized as a side effect of post-breast cancer treatment. It is one of the primary contributors to discomfort and reduced range of motion following breast cancer surgery. Due to severe pain, patients often experience difficulty moving their arms, particularly with shoulder flexion and abduction, which are the most affected movements. After an axillary lymph node dissection (ALND), cords, webs, or adhesions can be felt and seen in areas such as the axilla, breast, antecubital region, chest wall, hands, and arms. These fibrous bands restrict shoulder movement, especially limiting flexion and abduction. Methodology: The study was a randomized clinical trial that commenced after receiving approval from the ethical research committee. Data collection took place at HACC Hospital in Ahmedabad, across the In-patient Department, Out-patient Department, and Physiotherapy Department. Thirty patients were contacted two months after their breast cancer surgery. The ST-AWS questionnaire was used to assess the risk of developing axillary web syndrome and to assist patients in determining if they had AWS by completing a self-assessment. Result: Data analysis and distribution for both groups were conducted using Excel 2016. In the experimental group, the pre-therapy score was 76%, while the post-therapy score dropped to 36%, reflecting a 40% difference between pre-and post-therapy. For the control group, the pre-therapy score was also 76%, with the post-therapy score decreasing to 41%, resulting in a 35% difference between pre-and post-therapy. Conclusion: The study concludes that both soft tissue mobilization and stretching are effective treatments for patients with AWS. However, soft tissue mobilization proves to be more effective than stretching. Furthermore, prehabilitation can also play an important role in reducing the risk of axillary web syndrome. Keywords: Axillary web syndrome, post breast cancer surgery, soft tissue release, stretching, exercise therapy

IFlpMosaics enable the multispectral barcoding and high-throughput comparative analysis of mutant and wild-type cells.

To understand gene function, it is necessary to compare cells carrying the mutated target gene with normal cells. In most biomedical studies, the cells being compared are in different mutant and control animals and, therefore, do not experience the same epigenetic changes and tissue microenvironment. The experimental induction of genetic mosaics is essential to determine a gene cell-autonomous function and to model the etiology of diseases caused by somatic mutations. Current technologies used to induce genetic mosaics in mice lack either accuracy, throughput or barcoding diversity. Here we present the iFlpMosaics toolkit comprising a large set of new genetic tools and mouse lines that enable recombinase-dependent ratiometric induction and single-cell clonal tracking of multiple fluorescently labeled wild-type and Cre-mutant cells within the same time window and tissue microenvironment. The labeled cells can be profiled by multispectral imaging or by fluorescence-activated flow cytometry and single-cell RNA sequencing. iFlpMosaics facilitate the induction and analysis of genetic mosaics in any quiescent or progenitor cell, and for any given single or combination of floxed genes, thus enabling a more accurate understanding of how induced genetic mutations affect the biology of single cells during tissue development, homeostasis and disease.

Association of DNA methylation of RASSF1A and SHOX2 with lung cancer risk: A systematic review and meta-analysis.

This study estimates the research upon the potential worth of Ras association domain family member 1 A (RASSF1A) and short stature homeobox 2 (SHOX2) DNA methylation in lung cancer (LC) diagnosis. Open-published research was searched through PubMed, EMBASE, the Cochrane Library, Web of Science, China National Knowledge Infrastructure, and Chinese Biology Medicine Literature Database. Data on true positives, false positives, false negatives, and true negatives were extracted. This meta-analysis included 22 studies encompassing 4109 subjects (2427 LC patients and 1682 controls). The combined sensitivity, specificity, and area under the curve for RASSF1A and SHOX2 DNA methylation were 0.77 (95% CI: 0.71-0.81), 0.90 (95% CI: 0.87-0.92), and 0.92 (95% CI: 0.87-0.92), respectively. The pooled positive likelihood ratio and negative likelihood ratio were 7.5 (5.9-9.7) and 0.26 (0.21-0.32). The combined diagnostic odds ratio was 29 (95% CI: 20-41). RASSF1A and SHOX2 DNA methylation may emerge as potential diagnostic biomarkers for early-stage LC.

TERT promoter mutations in gliomas: Molecular roles in tumorigenesis, metastasis, diagnosis, prognosis, therapeutic targeting, and drug resistance.

Telomerase reverse transcriptase (TERT), a critical player in cellular immortalization, has emerged as a focal point of investigation due to its frequent promoter mutations in various human malignancies. TERT promoter mutations exhibit a significant role in tumorigenesis, fostering unbridled cellular proliferation and survival. This comprehensive review delves into the landscape of TERT promoter mutations and their profound implications in cancer, particularly within the context of gliomas. This article meticulously examines the intricate interplay between TERT promoter mutations and the metastatic cascade, shedding light on their capacity to orchestrate invasive behavior in gliomas. Moreover, this review describes the recent trends in therapeutic targeting of the TERT and dissects the evolving landscape of drug resistance associated with TERT mutations, providing insights into potential therapeutic challenges. In addition, the diagnostic and prognostic implications of TERT promoter mutations in gliomas are scrutinized, unraveling their potential as robust biomarkers. It also discusses the recent advancements in molecular diagnostics, illustrating the promise of TERT mutations as diagnostic tools and prognostic indicators. This review collectively aims to contribute to a deeper understanding of TERT promoter mutations in gliomas, offering a foundation for future research endeavors and paving the way for innovative strategies in glioma management.

The Use of POCUS to Identify Subgaleal Fluid Collections and Intracranial Infections.

Point-of-care ultrasound (POCUS) has been useful in describing soft tissue infections, such as cellulitis and abscesses. There has been limited use of ultrasound to describe findings of intracranial infections, such as Pott's puffy tumor, in cases of forehead prominence and signs of infection. In this case series we present POCUS findings in 2 cases of intracranial infections and one case of soft tissue edema without intracranial involvement from a single pediatric tertiary care center. Ultrasound findings revealed subgaleal fluid collections with associated periosteal lifting of the frontal bone in cases of Pott's Puffy tumor and intracranial infection, but no bony disruption or periosteal lifting in the patient with traumatic soft tissue edema. As pediatric intracranial infections may continue to have uncharacteristic seasonal peaks, POCUS may be considered as a first-line imaging technique for patients presenting with forehead swelling for differentiating infectious and traumatic etiologies as well as judging the need for further imaging techniques such as computed tomography and magnetic resonance imaging.
