Article Synopsis
  • Rapid vaccine development was essential for controlling the COVID-19 pandemic, and understanding vaccine-related physiological responses is key for fostering trust in medical practices.
  • This study focused on analyzing changes in breathing rate, heart rate, skin temperature, and menstrual cycle phases in over 17,000 participants in the Netherlands before and after COVID-19 vaccination.
  • Results showed short-term increases in breathing and heart rates after vaccination but no long-term effects, indicating that vaccines do not lead to chronic physiological issues.

Article Synopsis
  • The study examined sex-specific differences in physiological responses to COVID-19 using data from 1,163 participants monitored with a wearable device that measured breathing rate, heart rate, heart rate variability, and skin temperature.
  • Findings revealed that men experienced more significant physiological changes during COVID-19 infection compared to women, including greater increases in skin temperature and breathing rate, as well as greater decreases in heart rate variability.
  • The research highlights the importance of considering sex as a biological variable in health technologies and contributes to the understanding of personalized medicine approaches based on these physiological differences.

Extraction of subsets of highly connected nodes ("communities" or modules) is a standard step in the analysis of complex social and biological networks. We here consider the problem of finding a relatively small set of nodes in two labeled weighted graphs that is highly connected in both. While many scoring functions and algorithms tackle the problem, the typically high computational cost of permutation testing required to establish the -value for the observed pattern presents a major practical obstacle.

Although systemic chemotherapy remains the standard of care for TNBC, even combination chemotherapy is often ineffective. The identification of biomarkers for differential chemotherapy response would allow for the selection of responsive patients, thus maximizing efficacy and minimizing toxicities. Here, we leverage TNBC PDXs to identify biomarkers of response.

Genome in a Bottle benchmarks are widely used to help validate clinical sequencing pipelines and develop variant calling and sequencing methods. Here we use accurate linked and long reads to expand benchmarks in 7 samples to include difficult-to-map regions and segmental duplications that are challenging for short reads. These benchmarks add more than 300,000 SNVs and 50,000 insertions or deletions (indels) and include 16% more exonic variants, many in challenging, clinically relevant genes not covered previously, such as .

Introduction: Severe aortic stenosis, a highly-common valve disease in the elderly, has a poor prognosis if left untreated. To address the concern of effective procedures for severe aortic stenosis, a systematic TAVI program was established at the Dedinje Cardiovascular Institute (Belgrade, Serbia).

Methods: Our cohort was composed of 56 patients (74±15 years old).

Purpose: Carotid artery stenting (CAS) is an option for carotid restenosis (CR) treatment with favorable outcomes. However, CAS has also emerged as an alternative to carotid endarterectomy (CEA) for the management of patients with primary carotid stenosis. This study aimed to report CR rates after CAS was performed in patients with primary lesions versus restenosis after CEA, to identify predictors of CR, and to report both neurological and overall outcomes.

Containing the COVID-19 pandemic requires rapidly identifying infected individuals. Subtle changes in physiological parameters (such as heart rate, respiratory rate, and skin temperature), discernible by wearable devices, could act as early digital biomarkers of infections. Our primary objective was to assess the performance of statistical and algorithmic models using data from wearable devices to detect deviations compatible with a SARS-CoV-2 infection.

Accidental detachment of mechanical valve leaflet during implantation is a rare and potentially serious complication. When the lost leaflet cannot be found by direct visualisation, additional diagnostic procedures are necessary to detect it. Computer tomography is the best detection method, but the patient needs reoperation.

The complete understanding of the genomic contribution to complex traits, diseases, and response to treatments, as well as genomic medicine application to the well-being of all humans will be achieved through the global variome that encompasses fine-scale genetic diversity. Despite significant efforts in recent years, uneven representation still characterizes genomic resources and among the underrepresented European populations are the Western Balkans including the Serbian population. Our research addresses this gap and presents the first ever targeted sequencing dataset of variants in clinically relevant genes.

Background: To date, all published studies analyzing simultaneous treatment of carotid and proximal atherosclerotic lesions are describing retrograde approach and several technical variations. In the presented study, for the first time, antegrade approach is described for simultaneous carotid endarterectomy (CEA) and associated brachiocephalic trunk (BCT) or common carotid artery (CCA) angioplasty in the hybrid operating room.

Methods: From January 2012 till January 2016, antegrade hybrid procedures were performed in 18 patients.

This paper summarizes the results of a two-day dynamic monitoring of Michelangelo's David subject to environmental loads (city traffic and pedestrian loading induced by tourists visiting the Accademia Gallery). The monitoring was carried out by a no-contact technique using an interferometric radar, whose effectiveness in measuring the resonant frequencies of structures and historic monuments has proved over the last years through numerous monitoring activities. Owing to the dynamic behavior of the measurement system (radar and tripod), an accelerometer has been installed on the radar head to filter out the movement component of the measuring instrument from the measurement of the David's displacement.

We present the case of a patient with extremely rare associated congenital anomalies: thoracic aorta coarctation and left ectopic kidney with pelvic presentation. A 45-year-old male patient was admitted to our institution for multidetector computed tomography (MDCT) angiography. On admission, he complained of intermittent claudication after 10 meters of walking, frequent chest pain, and hypertension crisis.

We present a rare case of anterior nutcracker syndrome caused by an abdominal aorta aneurysm (AAA). A 61-year-old woman was admitted to our institution for computed tomography angiography. It revealed an AAA 51 mm in diameter that was lifting off of the left renal vein toward the superior mesenteric artery, causing anterior nutcracker syndrome with consequent left renal vein compression and left ovarian vein congestion.

Introduction: The natural course of abdominal aneurysms is progressive expansion, rupture, embolisation, thrombosis and compression of the visceral organs. The majority of papers report that inflammatory aortic and iliac aneurysms are associated with perianeurysmal and retroperitoneal fibrosis that ultimately results in the structural compromise of the urinary tract. Ureteral obstruction occurs in 20% to 71% of cases and approximately one half of these patients will present with obstructive uropathy.
