Aim: Study effects of microwave electromagnetic radiation (EMR) of the SHF range in vitro on viability and functional status of neutrophilic granulocytes.
Materials And Methods: Neutrophils of peripheral blood of 30 conditionally healthy donors aged 18 - 20 years were exposed to the effect of broadband (natural, similar to sun radio emission) and, mono-frequency (technogenic, similar to emission of cell phones, PCs, microwave ovens, etc.) EMR with frequency range of 4 - 4.34 GHz, generated by a SHF-generator <
Results: The amount of viable neu- trophils significantly reduced after the effect of modelled EMR with technogenic frequency- temporal structure, functional status of viable cells did not change. Neutrophils retained viability after the effect of EMR of natural origin, increased levels of IL1β and TNFα was determined in supernatants, functional status of neutrophils of men remained stable, and in women an increase of phagocytic ability and a reduction of production of oxygen radicals was noted.
Conclusion: The detected reduction of the amount of viable neutrophils under the effect of EMR of technogenic origin could result in disturbances in the system of innate immunity, other homeostasis elements of the human organism and development of pathologic conditions. At the same time, the de- tected effects of EMR of natural origin. open perspectives of use of modelled microwave EMR of SHF range in prophylaxis and clinical medicine.

Valved Pulmonary-to-Systemic Shunt for Pulmonary Arterial Hypertension in Two 5-Year-Old Patients.
Ann Thorac Surg Short Rep
June 2023
Division of Cardiac Surgery, Department of Surgery, Keck School of Medicine of the University of Southern California, Los Angeles, California.
We report the use of a unidirectional-valved pulmonary-to-systemic shunt to manage advanced pulmonary arterial hypertension in two 5-year-old patients. After failure of medical therapy, both patients underwent placement of a valved pulmonary-to-systemic shunt to allow right ventricular unloading at suprasystemic pulmonary pressures. Postoperative imaging demonstrated exclusive, intermittent right-to-left flow through the shunt.

Department of Surgery, University of Michigan, Ann Arbor, Michigan.
Background: The use of telehealth has grown exponentially since the COVID-19 pandemic. The safety of an initial telehealth preoperative evaluation for patients undergoing general thoracic procedures is unknown.
Methods: We retrospectively reviewed all patients who underwent a general thoracic surgical procedure at our academic tertiary care institution from January 2021 to December 2022.
Predicting loss of independence among geriatric patients following gastrointestinal surgery.

Department of Surgery, University of Virginia, Charlottesville, Virginia, USA.
Background: While existing risk calculators focus on mortality and complications, elderly patients are concerned with how operations will affect their quality of life, especially their independence. We sought to develop a novel clinically relevant and easy-to-use score to predict elderly patients' loss of independence after gastrointestinal surgery.
Methods: This retrospective cohort study included patients age ≥ 65 years enrolled in the American College of Surgeons National Surgical Quality Improvement Program database and Geriatric Pilot Project who underwent pancreatic, colorectal, or hepatic surgery (January 1, 2014- December 31, 2018).
Real-world evidence of remdesivir in formerly hospitalized COVID-19 patients: patient-reported and functional outcomes.
BMC Infect Dis
January 2025
Department of Pulmonology, Semmelweis University, Budapest, Hungary.
Background: Post-COVID condition (PCC) is characterized by persisting symptoms after the resolution of acute COVID-19. Remdesivir (RDV), a broad-spectrum antiviral drug, has been widely used in patients hospitalized with COVID-19 requiring oxygen therapy. We aimed to evaluate the effects of RDV on PCC by assessing patient-reported and functional outcomes.

Mitochondria play a crucial role in maintaining cellular health. It is interesting that the shape of mitochondria can vary depending on the type of cell, mitochondrial function, and other cellular conditions. However, there are limited studies that link functional assessment with mitochondrial morphology evaluation at high magnification, even fewer that do so in situ and none in human muscle biopsies.
