Revolutionary advancements in regenerative medicine have brought stem cell therapy to the forefront, offering promising prospects for the regeneration of ischemic cardiac tissue. Yet, its full ...efficacy, safety, and role in treating ischemic heart disease (IHD) remain limited. This literature review explores the intricate mechanisms underlying stem cell therapy. Furthermore, we unravel the innovative approaches employed to bolster stem cell survival, enhance differentiation, and seamlessly integrate them within the ischemic cardiac tissue microenvironment. Our comprehensive analysis uncovers how stem cells enhance cell survival, promote angiogenesis, and modulate the immune response. Stem cell therapy harnesses a multifaceted mode of action, encompassing paracrine effects and direct cell replacement. As our review progresses, we underscore the imperative for standardized protocols, comprehensive preclinical and clinical studies, and careful regulatory considerations. Lastly, we explore the integration of tissue engineering and genetic modifications, envisioning a future where stem cell therapy reigns supreme in regenerative medicine.
Pediatric brain tumors, including medulloblastoma (MB), represent a significant challenge in clinical oncology. Early diagnosis, accurate monitoring of therapeutic response, and the detection of ...minimal residual disease (MRD) are crucial for improving outcomes in these patients. This review aims to explore recent advancements in liquid biopsy techniques for monitoring pediatric brain tumors, with a specific focus on medulloblastoma. The primary research question is how liquid biopsy techniques can be effectively utilized for these purposes. Liquid biopsies, particularly the analysis of circulating tumor DNA (ctDNA) in cerebrospinal fluid (CSF), are investigated as promising noninvasive tools. This comprehensive review examines the components of liquid biopsies, including ctDNA, cell-free DNA (cfDNA), and microRNA (miRNA). Their applications in diagnosis, prognosis, and MRD assessment are critically assessed. The review also discusses the role of liquid biopsies in categorizing medulloblastoma subgroups, risk stratification, and the identification of therapeutic targets. Liquid biopsies have shown promising applications in the pediatric brain tumor field, particularly in medulloblastoma. They offer noninvasive means of diagnosis, monitoring treatment response, and detecting MRD. These biopsies have played a pivotal role in subgroup classification and risk stratification of medulloblastoma patients, aiding in the identification of therapeutic targets. However, challenges related to sensitivity and specificity are noted. In conclusion, this review highlights the growing importance of liquid biopsies, specifically ctDNA analysis in CSF, in pediatric brain tumor management, with a primary focus on medulloblastoma. Liquid biopsies have the potential to revolutionize patient care by enabling early diagnosis, accurate monitoring, and MRD detection. Nevertheless, further research is essential to validate their clinical utility fully. The evolving landscape of liquid biopsy applications underscores their promise in improving outcomes for pediatric brain tumor patients.
We report on an interdisciplinary scoping review project that sought to broadly review relevant methodological approaches to community engagement in pandemic prevention research. We reviewed ...abstracts for 1,000 published articles and 211 full-text articles that fell under search terms related to community engagement in infectious disease outbreak communication. We identified 71 papers from across a wide range of disciplines that embraced the spirit of participatory research and that can serve as models in ongoing pandemic science collaborations. While equity-driven participatory design of communication has not taken hold in literature about communication in the face of public health emergencies of international concern, there are positive signs of increasing advocacy for, and—to a lesser degree—uptake of non-extractive research practices in this context.
Research regarding the relationship between family communication and comorbid diagnoses in youths diagnosed with Bipolar Disorders is scarce. Existing research supports the importance of family ...communication with psychological development of children and adolescents affected by mental illness. The disruptive nature and increased dangers associated with Bipolar Disorders justifies further research. This dissertation study used archival data to answer research hypotheses to gain understanding the relationship between family communication and a diagnosis of a Bipolar Disorder. General Linear Model analysis and Analysis of Variance were used to test for significant differences in family functioning between families where a youth member had a diagnosis of a Bipolar Disorder versus varied comorbid diagnoses. Comorbid diagnoses configurations were the independent variables. The diagnoses configurations compared were a Bipolar Disorder only, compared to a Bipolar Disorder and any other diagnosis on Axis I; A Bipolar Disorder only, compared to a Bipolar Disorder and ADHD; A Bipolar Disorder only, compared to a Bipolar Disorder and Substance Disorder; and a Bipolar Disorder only, compared to a Bipolar Disorder, ADHD and Substance Disorder. Family functioning was assessed by three dependent variables which were the General Functioning, Problem Solving and Family Communication subscales of the Family Assessment Device (Epstein, Baldwin, & Bishop, 1983). Family communication was not found to be statistically significant for any comorbid combination tested. General functioning and problem solving were statistically significant but small sample sizes prohibit generalizations. Limitations included small sample sizes, individual rather than multiple family member assessment and the omission of nonverbal behaviors as a form of communication. Discussion explores possible factors accounting for insignificance and low sample sizes.
The best treatment of bile duct lithiasis in the era of the laparoscopic cholecystectomy has not yet been defined, as we can choose between different kinds of therapies which range from the ...traditional laparotomic treatment to the more modern endoscopic and laparoscopic techniques. Although in some centres a wholly laparoscopic access to the bile duct is used, we believe that the fastest, safest and most reliable method is still the sequential treatment, endoscopic and laparoscopic. In our experience the endoscopic cleaning of the choledochus was performed in 87.1% of the cases, with no mortality and 4.2% morbidity.
Seasonal grain workers in Western Australia who develop respiratory symptoms after exposure to grain dust develop concomitant changes in lung function and bronchial responsiveness to methacholine. ...The mechanisms underlying these changes are not known. A detailed study was undertaken of seasonal grain workers in Western Australia to evaluate the effect of nedocromil sodium (Fisons, United Kingdom) on these changes to see if they could be prevented by this drug. Forty seven subjects participated. Symptoms and forced expiratory volume in one second (FEV1) were recorded before the study and before, during, and after each working shift, and bronchial responsiveness to methacholine was measured at the beginning and end of the study. Twenty three subjects received nedocromil and 22 received a placebo in a double blind design; there was no difference in baseline characteristics between the two groups. At the end of the study, no differences were found between the nedocromil and placebo groups in the prevalence of symptoms or development of new symptoms during the study. The drug had no effect on changes in methacholine PD20 or FEV1. As in previous studies, new symptoms developing during the season were more common in atopic subjects and were associated with a fall in methacholine PD20. It is concluded that nedocromil has no effect on the development of new symptoms in grain workers. The mechanisms underlying these symptoms require further study.
The Authors report a case of Wilkie's syndrome recently observed. This unusual observation is suitable for some clinical and therapeutic considerations. X-ray examination and abdominal CT played a ...decisive role for the diagnosis. Among the large number of operations till now proposed for the management of this syndrome, the Authors preferred the latero-terminal duodeno-jejunum anastomosis. Such intervention, in fact, is easy and quick and allows to preserve a physiological intestinal function.
