This research project was designed to evaluate the degree of electromagnetic interference with cardiac implantable electronic devices (CIEDs) under simulated and benchtop conditions, and to assess these findings against the maximum values specified in the ISO 14117 standard for such devices.
Simulations on computable models, male and female, led to the identification of interference at the pacing electrodes. Representative CIEDs from three different manufacturers, as detailed in the ISO 14117 standard, were also subjected to a benchtop evaluation.
The simulations demonstrated voltage values exceeding the predefined thresholds for the ISO 14117 standard, suggesting the presence of interference. The interference levels fluctuated according to the bioimpedance signal's frequency and amplitude, and also differed between male and female subjects. Smart watches generated more interference than comparable simulations of smart scales and smart rings. The generators of various device manufacturers showed susceptibility to over-sensing and pacing inhibition across different signal amplitudes and frequencies.
This study employed both simulation and testing methodologies to evaluate the safety of smart scales, smart watches, and smart rings, all featuring bioimpedance technology. Our findings suggest that these consumer electronics might disrupt the operation of CIEDs in patients. These findings, concerning the potential for interference, advise against deploying these devices within this demographic.
By employing simulation and testing protocols, this study determined the safety implications of smart scales, smart watches, and smart rings, all leveraging bioimpedance technology. These consumer electronic devices, according to our research, may impede the operation of CIEDs in patients. The current data suggests against utilizing these devices in this group, due to the potential for disruption.
Macrophages, a crucial component of the innate immune system, play a significant role in both physiological processes and disease modulation, including responses to therapeutic interventions. Ionizing radiation, a common approach to cancer treatment, is also used, in smaller amounts, to augment therapies for inflammatory illnesses. Ionizing radiation, at lower doses, generally prompts anti-inflammatory reactions, whereas higher doses, employed in cancer therapies, often provoke inflammatory responses alongside tumor control. urine liquid biopsy Macrophage studies conducted outside a living system generally uphold this principle; however, in live organisms, tumor-associated macrophages, for example, exhibit a conflicting response within the specified dosage range. While certain aspects of how radiation impacts macrophage modifications have been documented, the underlying mechanisms by which these alterations are brought about remain unclear. see more However, their essential role in the human body makes them a compelling target for therapeutic interventions, possibly leading to improved treatment results. This report summarizes the current state of knowledge regarding the radiation responses of macrophages.
Cancer management necessitates the fundamental use of radiation therapy. However, concurrent with the constant improvement in radiotherapy techniques, the clinical significance of radiation-induced side effects is undiminished. For patients undergoing ionizing radiation, the mechanisms of acute toxicity and the development of late fibrosis represent critical areas of translational research for improving quality of life. The complex pathophysiology of radiotherapy-induced tissue changes includes macrophage activation, cytokine cascades, fibrotic alterations, vascular disorders, hypoxia, tissue destruction, and the consequent chronic wound healing process. Subsequently, a considerable body of data illustrates how these changes impact the irradiated stroma's role in oncogenesis, exhibiting intricate connections between tumor radiation response and the pathways associated with fibrosis. This review explores the mechanisms of radiation-induced normal tissue inflammation, highlighting its effect on treatment-related toxicities and the oncogenic process. Timed Up-and-Go Discussions also encompass potential targets for pharmacomodulation.
Over the recent years, there has been a noticeable increase in the evidence that radiation therapy alters the function of the immune system. Radiotherapy treatment can alter the tumoral microenvironment, leading to a shift in equilibrium towards a more immunostimulatory or immunosuppressive microenvironment. The immune response triggered by radiation therapy is seemingly contingent on the irradiation configuration (dose, particle, fractionation) and the delivery methods (dose rate, spatial distributions). An optimal irradiation approach (in terms of dose, temporal fractionation, spatial distribution, etc.) remains elusive. However, temporal fractionation strategies using high doses per fraction seem to favor the induction of radiation-induced immune responses through the pathway of immunogenic cell death. The release of damage-associated molecular patterns, coupled with the sensing of double-stranded DNA and RNA breaks, drives immunogenic cell death, thereby activating both the innate and adaptive immune responses that lead to tumor infiltration by effector T cells and the abscopal effect. Novel radiotherapy approaches, including FLASH and spatially fractionated radiotherapies (SFRT), significantly influence the technique of dose delivery. With the application of FLASH-RT and SFRT, effective immune system activation is achievable, paired with the preservation of intact healthy surrounding tissue. In this manuscript, the current state of knowledge regarding the immunomodulatory effects of these novel radiotherapy modalities on tumor cells, healthy immune cells, and nontargeted regions, and their synergistic potential with immunotherapy, is discussed.
Chemoradiation (CRT) is a typical therapeutic intervention in the management of local cancers, especially those that are locally advanced in nature. CRT has been shown, through research in both pre-clinical and human studies, to induce considerable anti-tumor responses, involving multiple facets of the immune system. CRT efficacy is examined in this review, highlighting its diverse immune consequences. Specifically, immunological cell death, the activation and maturation of antigen-presenting cells, and the stimulation of an adaptive anti-tumor immune response are linked to CRT's action. Just as in other therapeutic approaches, immunosuppressive mechanisms, notably those of Treg and myeloid origin, may, in specific instances, lessen the efficacy of CRT. Therefore, we have considered the utility of combining CRT with other therapies to strengthen the anti-tumor responses produced by CRT.
The substantial body of evidence underscores fatty acid metabolic reprogramming as a major regulator of anti-tumor immune responses, influencing the development and actions of immune cells. Subsequently, the metabolic signals arising from the tumor microenvironment cause variations in the tumor's fatty acid metabolism, subsequently tilting the balance of inflammatory signals, either supporting or impeding anti-tumor immune responses. The oxidative stressors, reactive oxygen species generated by radiation therapy, can reorganize a tumor's energy supply, implying that radiation therapy may further disrupt tumor energy metabolism by stimulating the synthesis of fatty acids. This critical review dissects the complex interplay between the fatty acid metabolic network and immune responses, especially with respect to radiation therapy's influence.
The physical properties afforded by charged particle radiotherapy, particularly those employing protons and carbon ions, facilitate volume-conformal irradiation, minimizing the overall dose to healthy tissue. Carbon ion therapy exhibits a heightened biological efficacy, leading to distinctive molecular consequences. Immunotherapy, centered around immune checkpoint inhibitors, is currently viewed as a crucial element in the management of cancer. We examine preclinical data regarding the potent pairing of charged particle radiotherapy and immunotherapy, based on the radiotherapy's beneficial properties. A deeper exploration of this combined treatment is deemed necessary, with a focus on its clinical applicability, given the presence of various established research initiatives.
Health information, routinely generated within a healthcare setting, is crucial for effective healthcare policy formulation, program planning, monitoring and evaluation, and overall service delivery. Numerous individual research papers in Ethiopia explore the utilization of routine health information, but the results obtained from each are not uniform.
This review aimed to combine the measurement of routine health information use and its contributing factors amongst the healthcare providers of Ethiopia.
PubMed, Global Health, Scopus, Embase, African Journal Online, Advanced Google Search, and Google Scholar were queried for relevant information between August 20th and 26th of 2022.
A broad search yielded 890 articles; unfortunately, only 23 of them met the requirements for inclusion. Across all the studies, 8662 participants (representing 963% of the planned sample) were scrutinized. A meta-analysis of routine health information use demonstrated a pooled prevalence of 537%, with a 95% confidence interval of 4745% to 5995%. Among healthcare providers, factors like training (adjusted OR=156, 95%CI=112 to 218), competency in data management (AOR=194, 95%CI=135 to 28), availability of standard guidelines (AOR=166, 95%CI=138 to 199), supportive supervision (AOR=207, 95%CI=155 to 276), and feedback mechanisms (AOR=220, 95%CI=130 to 371) were all significantly linked to the utilization of routine health information, with p<0.05 and 95% confidence intervals.
One of the most significant difficulties in health information systems lies in applying routinely produced health data to evidence-based decision-making. Health authorities in Ethiopia are advised by the study's reviewers to proactively invest in upskilling their staff on utilizing routinely generated health information.
