Shedding light on vitamin D in tuberculosis: A comprehensive review of clinical trials and discrepancies.

Over the past few decades, there has been extensive research on the use of vitamin D as an adjunctive therapy in the treatment and prevention of tuberculosis. In vitro studies have provided valuable insights into the mechanisms by which vitamin D activates the immune response to combat Mycobacterium tuberculosis. These encouraging findings have spurred clinical investigations globally to assess the effectiveness of vitamin D as a preventive measure and as an adjunctive treatment for tuberculosis. However, the results from these clinical studies have been contradictory, with some demonstrating clear efficacy while others report only modest or no activity. In this review, we aim to analyze the clinical studies on vitamin D and examine the possible discrepancies observed in their outcomes.

Promoting the process of determining brain death through standardized training.

Objective: This study aims to explore the training mode for brain death determination to ensure the quality of subsequent brain death determination. Methods: A four-skill and four-step (FFT) training model was adopted, which included a clinical neurological examination, an electroencephalogram (EEG) examination, a short-latency somatosensory evoked potential (SLSEP) examination, and a transcranial Doppler (TCD) examination. Each skill is divided into four steps: multimedia theory teaching, bedside demonstration, one-on-one real or dummy simulation training, and assessment. The authors analyzed the training results of 1,577 professional and technical personnel who participated in the FFT training model from 2013 to 2020 (25 sessions), including error rate analysis of the written examination, knowledge gap analysis, and influencing factors analysis. Results: The total error rates for all four written examination topics were < 5%, at 4.13% for SLSEP, 4.11% for EEG, 3.71% for TCD, and 3.65% for clinical evaluation. The knowledge gap analysis of the four-skill test papers suggested that the trainees had different knowledge gaps. Based on the univariate analysis and the multiple linear regression analysis, among the six factors, specialty categories, professional and technical titles, and hospital level were the independent influencing factors of answer errors (p < 0.01). Conclusion: The FFT model is suitable for brain death (BD) determination training in China; however, the authors should pay attention to the professional characteristics of participants, strengthen the knowledge gap training, and strive to narrow the difference in training quality.

[Chronology of the ISO 9001:2015 certification and satisfaction survey in the multidisciplinary Clinical Investigation Center (CIC) of the historic Saint-Louis Hospital during the COVID-19 pandemic]. / Chronologie de la certification ISO 9001:2015 et enquête de satisfaction au sein du centre d'investigations cliniques plurithématique (CIC-P) de l'historique hôpital Saint-Louis en période de pandémie du COVID-19.

The main objectives of multidisciplinary clinical investigation center (CIC-P) are to facilitate the availability of new drugs for patients, to enhance the visibility and attractiveness of French clinical research, to improve the quality of early phase trials, and to enhance the value of academic research by evaluating molecules in rare diseases. Since 2017, the CIC-P has been committed to a quality approach process, launching in 2018 its first satisfaction survey on patient care and clinical trial management of all its employees. A second satisfaction survey targeted by profession type was to be launched in 2020, in view of the requirements of the ISO 9001:2015 standard, but the process was interrupted following the coronavirus diseases 2019 (COVID-19) pandemic. The successful reorganization of the CIC-P activity during the first containment of the COVID-19 pandemic was driven by the implementation of a quality management system that promotes continuous improvement through the organization and involvement of all the staff. This voluntary and participative approach motivated the CIC-P to apply for the organizational sesame. The ISO 9001:2015 certification of CIC-P aims at increasing its performance, to satisfying its customers and to fully integrate its activities in a continuous improvement process, according to the requirements of this international standard, through the deployment of quality tools such as The Deming wheel (PDCA), an indispensable tool for transformation and reorganization; the analysis of the environment by the strengths, weakness, opportunities, threats (SWOT) analysis tool; the analysis and management of risks by the FMEA method, and all with performance indicators (SMART) and precise objectives at each stage of a project/process. The implementation of satisfaction questionnaires remains the essential tool for evaluating the expectations and needs of interested parties, but also for improving the quality of CIC-P activities and services. All these tools put in place have allowed us to continuously improve the means of production and to constantly improve our organization.

The therapeutic efficacy and mechanism action of Si Cao formula in the treatment of psoriasis: A pilot clinical investigation and animal validation.

ETHNOPHARMACOLOGICAL RELEVANCE: Psoriasis is a chronic inflammation and relapsing disease that affected approximately 100 million individuals worldwide. In previous clinical study, it was observed that the topical application of Si Cao Formula (SCF) ameliorated psoriasis skin lesions and reduced the recurrence rate of patients over a period of three months. However, the precise mechanism remains unclear. AIM OF THE STUDY: The objective of this study was to assess the effectiveness and safety of SCF in patients diagnosed with psoriasis and explore the molecular mechanisms that contribute to SCF's therapeutic efficacy in psoriasis treatment. MATERIALS AND METHODS: A randomized, controlled, and pilot clinical study was performed. This study assessed 30 individuals diagnosed with mild to moderate plaque psoriasis. 15 of them underwent local SCF treatment, the others received calcipotriol intervention. The outcome measure focused on Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and recurrence rate. In addition, IMQ-induced psoriasis-like mice model were used to assess the impact of SCF on ameliorating epidermal hyperplasia, suppressing angiogenesis, and modulating immune response. Furthermore, we performed bioinformatics analysis on transcriptome data obtained from skin lesions of mice model. This analysis allowed us to identify the targets and signaling pathways associated with the action of SCF. Subsequently, we conducted experimental validation to confirm the core targets. RESULTS: Our clinical pilot study demonstrated that SCF could ameliorate skin lesions in psoriasis patients with comparable efficacy of calcipotriol in drop of PASI and DLQI scores. SCF exhibited a significantly reduced recurrence rate within 12 weeks (33.3%). Liquid Chromatography Mass Spectrometry (LC-MS) identified 41 active constituents of SCF (26 cations and 15 anions). Animal experiments showed SCF ameliorates the skin lesions of IMQ-induced psoriasis like mice model and suppresses epidermal hyperkeratosis and angiogenesis. There were 845 up-regulated and 764 down-regulated DEGs between IMQ and IMQ + SCF groups. GO analysis revealed that DEGs were linked to keratinization, keratinocyte differentiation, organic acid transport epidermal cell differentiation, and carboxylic acid transport interferon-gamma production. KEGG pathway analysis showed that SCF may play a vital part through IL-17 and JAK/STAT signaling pathway. In addition, SCF could reduce the number of positive cells expressing PCNA, CD31, pSTAT3, CD3, and F4/80 within the epidermis of psoriatic lesions, as well as the expression of Il-17a and Stat3 in IMQ-induced psoriasis mice. CONCLUSIONS: Our research suggests that SCF serves as a reliable and efficient local approach for preventing and treating psoriasis. The discovery of plausible molecular mechanisms and therapeutic targets associated with SCF may support its broad implementation in clinical settings.

Evidence-based cutoffs for total and adjusted calcium: a major factor in detecting severe hypo- and hypercalcemia.

OBJECTIVES: Severe hypo- and hypercalcemia are common and urgent treatment is recommended. Free calcium (fCa) is the gold standard but needs blood gas tests with challenging preanalytics. Total calcium (tCa) and calculated adjusted calcium (aCa) are readily available, but their interpretation is hampered by identical tCa and aCa cutoffs, laborious local aCa calculation and difficult comparability of calcium biomarkers. METHODS: Laboratory results from University Medicine Leipzig were evaluated over a five-year period (236,274 patients). A local aCa equation was derived by linear least squares regression, the agreement between fCa, tCa and aCa assessed with Cohen's κ and decision thresholds derived by this indirect method. RESULTS: The local aCa equation was created from data of 9,756 patients, each with one paired measurement of tCa, fCa and albumin. Derived aCa cutoffs (1.95/3.15 mmol/L) differ markedly from derived tCa cutoffs (1.6/2.9 mmol/L) and severe hypo- and hypercalcemia can be more accurately assessed by aCa (κ=0.489, 0.812) than by tCa (κ=0.445, 0.744). Comparing our approach to standard care (tCa, literature cutoff), a total 3,250 of 3,680 (88.3 %) misclassified measurements were correctly classified when using aCa with evidence-based cutoffs. CONCLUSIONS: Optimized cutoffs for aCa and tCa hold great potential for improved patient care. Locally derived aCa equations differ mostly in the chosen mean normal calcium and provide minimal overall improvement, but entail a close examination of the used cutoffs before application.

European expert recommendations on clinical investigation and evaluation of high-risk medical devices for children.

Several high-risk medical devices for children have become unavailable in the European Union (EU), since requirements and costs for device certification increased markedly due to the EU Medical Device Regulation. The EU-funded CORE-MD project held a workshop in January 2023 with experts from various child health specialties, representatives of European paediatric associations, a regulatory authority and the European Commission Directorate General Health and Food Safety. A virtual follow-up meeting took place in March 2023. We developed recommendations for investigation of high-risk medical devices for children building on participants' expertise and results of a scoping review of clinical trials on high-risk medical devices in children. Approaches for evaluating and certifying high-risk medical devices for market introduction are proposed.

FAIR Health Informatics: A Health Informatics Framework for Verifiable and Explainable Data Analysis.

The recent COVID-19 pandemic has hit humanity very hard in ways rarely observed before. In this digitally connected world, the health informatics and investigation domains (both public and private) lack a robust framework to enable rapid investigation and cures. Since the data in the healthcare domain are highly confidential, any framework in the healthcare domain must work on real data, be verifiable, and support reproducibility for evidence purposes. In this paper, we propose a health informatics framework that supports data acquisition from various sources in real-time, correlates these data from various sources among each other and to the domain-specific terminologies, and supports querying and analyses. Various sources include sensory data from wearable sensors, clinical investigation (for trials and devices) data from private/public agencies, personnel health records, academic publications in the healthcare domain, and semantic information such as clinical ontologies and the Medical Subject Heading ontology. The linking and correlation of various sources include mapping personnel wearable data to health records, clinical oncology terms to clinical trials, and so on. The framework is designed such that the data are Findable, Accessible, Interoperable, and Reusable with proper Identity and Access Mechanisms. This practically means to tracing and linking each step in the data management lifecycle through discovery, ease of access and exchange, and data reuse. We present a practical use case to correlate a variety of aspects of data relating to a certain medical subject heading from the Medical Subject Headings ontology and academic publications with clinical investigation data. The proposed architecture supports streaming data acquisition and servicing and processing changes throughout the lifecycle of the data management. This is necessary in certain events, such as when the status of a certain clinical or other health-related investigation needs to be updated. In such cases, it is required to track and view the outline of those events for the analysis and traceability of the clinical investigation and to define interventions if necessary.

Multiple Protein Biomarkers and Different Treatment Strategies for Colorectal Carcinoma: A Comprehensive Prospective.

In this review, we emphasized important biomarkers, pathogenesis, and newly developed therapeutic approaches in the treatment of colorectal cancer (CRC). This includes a complete description of small-molecule inhibitors, phytopharmaceuticals with antiproliferative potential, monoclonal antibodies for targeted therapy, vaccinations as immunotherapeutic agents, and many innovative strategies to intervene in the interaction of oncogenic proteins. Many factors combine to determine the clinical behavior of colorectal cancer and it is still difficult to comprehend the molecular causes of a person's vulnerability to CRC. It is also challenging to identify the causes of the tumor's onset, progression, and responsiveness or resistance to antitumor treatment. Current recommendations for targeted medications are being updated by guidelines throughout the world in light of the growing number of high-quality clinical studies. So, being concerned about the aforementioned aspects, we have tried to present a summarized pathogenic view, including a brief description of biomarkers and an update of compounds with their underlying mechanisms that are currently under various stages of clinical testing. This will help to identify gaps or shortfalls that can be addressed in upcoming colorectal cancer research.

CoVSense: Ultrasensitive Nucleocapsid Antigen Immunosensor for Rapid Clinical Detection of Wildtype and Variant SARS-CoV-2.

The widespread accessibility of commercial/clinically-viable electrochemical diagnostic systems for rapid quantification of viral proteins demands translational/preclinical investigations. Here, Covid-Sense (CoVSense) antigen testing platform; an all-in-one electrochemical nano-immunosensor for sample-to-result, self-validated, and accurate quantification of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleocapsid (N)-proteins in clinical examinations is developed. The platform's sensing strips benefit from a highly-sensitive, nanostructured surface, created through the incorporation of carboxyl-functionalized graphene nanosheets, and poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) conductive polymers, enhancing the overall conductivity of the system. The nanoengineered surface chemistry allows for compatible direct assembly of bioreceptor molecules. CoVSense offers an inexpensive (<$2 kit) and fast/digital response (<10 min), measured using a customized hand-held reader (<$25), enabling data-driven outbreak management. The sensor shows 95% clinical sensitivity and 100% specificity (Ct<25), and overall sensitivity of 91% for combined symptomatic/asymptomatic cohort with wildtype SARS-CoV-2 or B.1.1.7 variant (N = 105, nasal/throat samples). The sensor correlates the N-protein levels to viral load, detecting high Ct values of ≈35, with no sample preparation steps, while outperforming the commercial rapid antigen tests. The current translational technology fills the gap in the workflow of rapid, point-of-care, and accurate diagnosis of COVID-19.

Characterizing the Current Clinical Trial Landscape in Spinal Deformity: A Retrospective Analysis of Trends in the ClinicalTrials.gov Registry.

BACKGROUND: The management of adult spinal deformity (ASD) relies upon retrospective data, but there have been calls for prospective trials to improve the evidentiary base. This study sought to define the state of the spinal deformity clinical trials and highlight trends to guide future research. METHODS: The ClinicalTrials.gov database was queried for all ASD trials initiated since 2008. ASD was defined as adults (>18 years) and defined by the trial. All identified trials were categorized by enrollment status, study design, funding source, start and completion dates, country, outcomes examined, among many other study characteristics. RESULTS: Sixty trials were included, of which 33(55.0%) started within the past 5 years of the query date. Most trials were sponsored by academic centers (60.0%) followed by industry (48.3%). Notably, 16 (27%) trials had multiple funding sources, all included collaboration with an industry entity. Only one trial had funding from a government agency. There were 30 (50%) interventional and 30 (50%) observational studies. The average time to completion was 50.8 ± 49.1 months. A total of 23 (38.3%) studies investigated a new procedural innovation, while 17 (28.3%) studies examined the safety or efficacy of a device. Study publications were associated with 17 (28.3%) trials in the registry. CONCLUSIONS: The number of trials has increased significantly over the past 5 years, with the bulk of trials being funded by academic centers and industry and a notably lack by government agencies. Most trials focused on device or procedural investigation. Despite growing interest in ASD clinical trials, there remain many points for improvement in the current evidentiary base.

One-Piece Zirconia Oral Implants for Single Tooth Replacement: Five-Year Results from a Prospective Cohort Study.

The intention of this 5-year prospective cohort investigation was to clinically and radiographically investigate the outcomes of a one-piece zirconia implant system for single tooth replacement. Sixty-five patients received a total of 66 single-tooth implants. All implants immediately received temporary restorations and were finally restored with all-ceramic crowns. Follow-ups were performed at the prosthetic delivery, after 1, 3, and 5 years. Peri-implant and dental soft-tissue parameters were evaluated and patient-reported outcomes recorded. To monitor peri-implant bone remodelling, standardised radiographs were taken at the implant insertion and at the 1-, 3-, and 5-year follow-ups. In the course of 5 years, 14 implants were lost, resulting in a cumulative implant survival rate of 78.2%. The mean marginal bone loss from the implant insertion to the 5-year follow-up amounted to 1.12 mm. Probing depth, clinical attachment level, bleeding, and plaque index increased over time. In 91.5% of the implants, the papilla index showed levels of 1 or 2, respectively. At the end of the study, the patient satisfaction was higher compared to the pre-treatment measurements. Due to the low survival rate after five years and the noticeably high frequency of advanced bone loss observed in this study, the implant has not met the launch criteria, as it would have not been recommended for routine clinical use.

One-Piece Zirconia Oral Implants for the Support of Three-Unit Fixed Dental Prostheses: Three-Year Results from a Prospective Case Series.

The objective was to investigate the clinical and radiological outcome of one-piece zirconia oral implants to support three-unit fixed dental prostheses (FDP) after three years in function. Twenty-seven patients were treated with a total of 54 implants in a one-stage surgery and immediate provisionalization. Standardized radiographs were taken at implant placement, after one year and after three years, to evaluate peri-implant bone loss. Soft-tissue parameters were also assessed. Linear mixed regression models as well as Wilcoxon Signed Rank tests were used for analyzing differences between groups and time points (p < 0.05). At the three-year evaluation, one implant was lost, resulting in a cumulative survival rate of 98.1%. The mean marginal bone loss amounted to 2.16 mm. An implant success grade I of 52% (bone loss of ≤2 mm) and success grade II of 61% (bone loss of ≤3 mm) were achieved. None of the evaluated baseline parameters affected bone loss. The survival rate of the zirconia implants was comparable to market-available titanium implants. However, an increased marginal bone loss was observed with a high peri-implantitis incidence and a resulting low implant success rate.

Pan-cancer antagonistic inhibition pattern of ATM-driven G2/M checkpoint pathway vs other DNA repair pathways.

DNA repair mechanisms keep genome integrity and limit tumor-associated alterations and heterogeneity, but on the other hand they promote tumor survival after radiation and genotoxic chemotherapies. We screened pathway activation levels of 38 DNA repair pathways in nine human cancer types (gliomas, breast, colorectal, lung, thyroid, cervical, kidney, gastric, and pancreatic cancers). We took RNAseq profiles of the experimental 51 normal and 408 tumor samples, and from The Cancer Genome Atlas and Clinical Proteomic Tumor Analysis Consortium databases - of 500/407 normal and 5752/646 tumor samples, and also 573 normal and 984 tumor proteomic profiles from Proteomic Data Commons portal. For all the samplings we observed a congruent trend that all cancer types showed inhibition of G2/M arrest checkpoint pathway compared to the normal samples, and relatively low activities of p53-mediated pathways. In contrast, other DNA repair pathways were upregulated in most of the cancer types. The G2/M checkpoint pathway was statistically significantly downregulated compared to the other DNA repair pathways, and this inhibition was strongly impacted by antagonistic regulation of (i) promitotic genes CCNB and CDK1, and (ii) GADD45 genes promoting G2/M arrest. At the DNA level, we found that ATM, TP53, and CDKN1A genes accumulated loss of function mutations, and cyclin B complex genes - transforming mutations. These findings suggest importance of activation for most of DNA repair pathways in cancer progression, with remarkable exceptions of G2/M checkpoint and p53-related pathways which are downregulated and neutrally activated, respectively.

MALDI-TOF-MS for Rapid Screening and Typing of ß-Globin Variant and ß-Thalassemia through Direct Measurements of Intact Globin Chains.

BACKGROUND: Traditional phenotype-based screening for ß-globin variant and ß-thalassemia using hematological parameters is time-consuming with low-resolution detection. Development of a MALDI-TOF-MS assay using alternative markers is needed. METHODS: We constructed a MALDI-TOF-MS-based approach for identifying various ß-globin disorders and classifying thalassemia major (TM) and thalassemia intermedia (TI) patients using 901 training samples with known HBB/HBA genotypes. We then validated the accuracy of population screening and clinical classification in 2 separate cohorts consisting of 16 172 participants and 201 ß-thalassemia patients. Traditional methods were used as controls. Genetic tests were considered the gold standard for testing positive specimens. RESULTS: We established a prediction model for identifying different forms of ß-globin disorders in a single MALDI-TOF-MS test based on δ- to ß-globin, γ- to α-globin, γ- to ß-globin ratios, and/or the abnormal globin-chain patterns. Our validation study yielded comparable results of clinical specificity (99.89% vs 99.71%), and accuracy (99.78% vs 99.16%) between the new assay and traditional methods but higher clinical sensitivity for the new method (97.52% vs 88.01%). The new assay identified 22 additional abnormal hemoglobins in 69 individuals including 9 novel ones, and accurately screened for 9 carriers of deletional hereditary persistence of fetal hemoglobin or δß-thalassemia. TM and TI were well classified in 178 samples out of 201 ß-thalassemia patients. CONCLUSIONS: MALDI-TOF-MS is a highly accurate, predictive tool that could be suitable for large-scale screening and clinical classification of ß-globin disorders.

Preparing healthcare, academic institutions, and notified bodies for their involvement in the innovation of medical devices under the new European regulation.

INTRODUCTION: Favoring innovation by making timely medical technology available to people and by securing patients' safety is a challenge. AREAS COVERED: The new European Medical Device Regulation (MDR) will have a central implication in the development of new devices and could affect their innovation and availability, as well as discourage investment in research within Europe. EXPERT OPINION: Start-ups and small companies might not be able to cope with the increasing complexity and the required changes of perspective. Health-care institutions are facing an increasing availability of complex technologies, while data on their clinical efficacy and cost-effectiveness are rarely provided. A partnership/collaboration between health-care institutions, academia, and private industries will enhance their own specific interests with the common goal of improving overall health and quality of life. The complexity of the subject combined with the variety of specialists and stakeholders involved requires the implementation, in hospital centers of clinical excellence, of units dedicated to the whole path of the medical device innovation. Stakeholders should quickly provide adequate measures to facilitate the complex medical device innovation path under the more stringent MDR aimed to increase safety and quality of care.

Dutch National Round Robin Trial on Plasma-Derived Circulating Cell-Free DNA Extraction Methods Routinely Used in Clinical Pathology for Molecular Tumor Profiling.

BACKGROUND: Efficient recovery of circulating tumor DNA (ctDNA) depends on the quantity and quality of circulating cell-free DNA (ccfDNA). Here, we evaluated whether various ccfDNA extraction methods routinely applied in Dutch laboratories affect ccfDNA yield, ccfDNA integrity, and mutant ctDNA detection, using identical lung cancer patient-derived plasma samples. METHODS: Aliquots of 4 high-volume diagnostic leukapheresis plasma samples and one artificial reference plasma sample with predetermined tumor-derived mutations were distributed among 14 Dutch laboratories. Extractions of ccfDNA were performed according to local routine standard operating procedures and were analyzed at a central reference laboratory for mutant detection and assessment of ccfDNA quantity and integrity. RESULTS: Mutant molecule levels in extracted ccfDNA samples varied considerably between laboratories, but there was no indication of consistent above or below average performance. Compared to silica membrane-based methods, samples extracted with magnetic beads-based kits revealed an overall lower total ccfDNA yield (-29%; P < 0.0001) and recovered fewer mutant molecules (-41%; P < 0.01). The variant allelic frequency and sample integrity were similar. In samples with a higher-than-average total ccfDNA yield, an augmented recovery of mutant molecules was observed. CONCLUSIONS: In the Netherlands, we encountered diversity in preanalytical workflows with potential consequences on mutant ctDNA detection in clinical practice. Silica membrane-based methodologies resulted in the highest total ccfDNA yield and are therefore preferred to detect low copy numbers of relevant mutations. Harmonization of the extraction workflow for accurate quantification and sensitive detection is required to prevent introduction of technical divergence in the preanalytical phase and reduce interlaboratory discrepancies.

Recommendations for the design and implementation of an Early Feasibility Studies program for medical devices in the European Union.

INTRODUCTION: Early Feasibility Studies (EFS) are among the pre-market clinical investigations allowed by the International Standard for Clinical investigation of medical devices (MD) for human subjects. The Food and Drug Administration (FDA) introduced an EFS program in the US in 2013. The European Union (EU) MD Regulation, that entered into force in May 2021, opened the possibility of EFS in the EU. However, European countries at present have no standardized procedural framework for EFS. In this paper, we address the desirability of a European EFS program. AREAS COVERED: Characteristics of EFS conducted so far are reviewed, and perceptions of an expert, multidisciplinary panel of key stakeholders are explored regarding desirability and feasibility of a European EFS program and critical factors favoring or hampering its implementation. EXPERT OPINION: Implementing an EFS program in the EU would contribute to creating a favorable environment for early-stage clinical investigations, with positive effects on the quality and timeliness of clinical evidence for novel MDs, and attractiveness of the European system for pre- and post-market clinical research. Based on discussion with experts, also leveraging on the US experience, three dimensions should be considered for effective design and implementation: process, resources, and ethical issues.

Inflammation and the role of infection: Complications and treatment options following neurotrauma.

Traumatic brain injury can have devastating consequences for patients and extended hospital stays and recovery course. Recent data indicate that the initial insult causes profound changes to the immune system and leads to a pro-inflammatory state. This alteration in homeostasis predisposes patients to an increased risk of infection and underlying autoimmune conditions. Increased emphasis has been placed on understanding this process both in the clinical and preclinical literature. This review highlights the intrinsic inflammatory conditions that can occur within the initial hospital stay, discusses long-term immune consequences, highlights emerging treatment options, and delves into important pathways currently being investigated with preclinical models.
