Instances of Biowarfare in World War I (1914-1918).

During World War I (WWI), also referred to as 'The Great War,' Germany implemented a pioneering biowarfare program as part of a broader military strategy to undermine Allied forces by targeting their logistical and supply capabilities. This initiative, unprecedented in its systematic and strategic application, utilized a variety of pathogens, primarily targeting animal populations, to disrupt support systems without contravening international laws, specifically the 1907 Hague Convention. The operations, shrouded in secrecy and largely led by the German General Staff, included sophisticated sabotage actions against both enemy and neutral states.

What kind of innovation state matters for social justice? Learning from Poulantzas and going beyond.

In the twenty-first century, the notion of the state and its role in innovation and development have become dominant topics of theoretical and empirical inquiry. Although contemporary innovation theorists clearly unpack the myth of market fundamentalism in industrial policy and practice of neo-liberal states, they do not seem to explain precisely how come such states have been justified to play extensive roles in the economy. This paper provides a theoretical explanation by drawing lessons from Poulantzas' approach to the state and going beyond it to consider alternatives.

Early Infirmaries in Methoni During the Venetian Occupation.

Introduction: In the High Middle Ages, Venetian sovereignty was recognized in Methoni and Koroni (in Greece). It helped lay the foundations for the prevalence of democracy in Venice in the Eastern Mediterranean. The development of these two decadent regions of Messinia, had to be supported by social welfare infrastructure.

Rethinking Fluid Responsiveness during Septic Shock: Ameliorate Accuracy of Noninvasive Cardiac Output Measurements through Evaluation of Arterial Biomechanical Properties.

Beat-to-beat estimates of cardiac output from the direct measure of peripheral arterial blood pressure rely on the assumption that changes in the waveform morphology are related to changes in blood flow and vasomotor tone. However, in septic shock patients, profound changes in vascular tone occur that are not uniform across the entire arterial bed. In such cases, cardiac output estimates might be inaccurate, leading to unreliable evaluation of fluid responsiveness.

The Hospital of Medieval Venetian Methoni.

In medieval Venetian Methoni, the provision of medical care could be roughly divided into two phases. During the first phase, Venice provided medical care solely to the staff, the garrison, and the Venetian citizens residing in Methoni. Medical care to the rest of the population was offered by the solitary orders that had settled in the area after the conquest of Methoni, in the context of charity.

Efficacy, Safety and Feasibility of Superior Vena Cava Isolation in Patients Undergoing Atrial Fibrillation Catheter Ablation: An Up-to-Date Review.

Pulmonary vein isolation (PVI) is the cornerstone in atrial fibrillation (AF) ablation; yet, the role of arrhythmogenic superior vena cava (SVC) is increasingly recognized and different ablation strategies have been employed in this context. SVC can act as a trigger or perpetuator of AF, and its significance might be more pronounced in patients undergoing repeated ablation. Several cohorts have examined efficacy, safety and feasibility of SVC isolation (SVCI) among AF patients.

The History of Anthrax Weaponization in the Soviet Union.

In this paper, we reveal the anthrax weaponization in the Soviet Union and its impact on biowarfare research, technology, and public health that resulted in the development of the first Soviet Anthrax vaccine and the subsequent vaccination of animals and humans en masse. We assume that there are cases that a biowarfare technology was incorporated into the civilian industry and benefited public health. However, the legacy of bioweapons today still poses an asymmetric threat to public health and safety.

Closed-Loop Microreactor on PCB for Ultra-Fast DNA Amplification: Design and Thermal Validation.

Polymerase chain reaction (PCR) is the most common method used for nucleic acid (DNA) amplification. The development of PCR-performing microfluidic reactors (μPCRs) has been of major importance, due to their crucial role in pathogen detection applications in medical diagnostics. Closed loop (CL) is an advantageous type of μPCR, which uses a circular microchannel, thus allowing the DNA sample to pass consecutively through the different temperature zones, in order to accomplish a PCR cycle.

Association of Pressure Wave Reflections With Left Ventricular Mass: a Systematic Review and Meta-Analysis.

Background: Pressure wave reflections (PWRs) within the circulation are assessed at various arterial sites by various noninvasive methods. We aimed at reviewing the conflicting data regarding the hypothesis that higher PWRs are associated with higher left ventricular mass and tested whether this association stands for all available indices of PWRs, all (proximal or distal to the heart) sites of assessment, and is modified by sex, age and heart rate.

Methods: Based on a predefined protocol applying the Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines, we identified eligible for meta-analysis data regarding: augmentation index, augmentation pressure, backward pressure (Pb), reflection index, and their association with left ventricular mass index (19 studies, total population n=8686).

Impaired left ventricular deformation and ventricular-arterial coupling in post-COVID-19: association with autonomic dysregulation.

Coronavirus disease-19 (COVID-19) has extended implications namely the long COVID-19 syndrome. We assessed over-time changes in left ventricular (LV) function, aortic stiffness, autonomic function, and ventricular-arterial coupling (VAC) in post-COVID-19 patients. We followed 34 post-COVID-19 subjects, up to 6 months post-hospital discharge.

Assessment of Early Markers of Cardiovascular Risk in Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is a heterogeneous syndrome, with long-term sequelae from birth to senescence. The long-term effects of PCOS are attributed to several metabolic aberrations ensuing the syndrome. In a systematic review of literature regarding the cardiovascular risk factors that accompany PCOS, we found that macrovascular function has been assessed by flow-mediated dilatation (FMD), microvascular function by venous occlusion plethysmography (VOP), and arterial structure by ultrasonographic assessment of intima-media thickness (IMT) usually of the carotid artery.

The effect of atropine used in dobutamine stress echocardiography on pupil diameter.

Background: The use of atropine during dobutamine stress echocardiography (DSE) is contraindicated in persons with narrow angle glaucoma though there is limited evidence that low doses of intravenous atropine do not cause pupillary dilation.

Objective: The aim of this study is to investigate whether atropine when administered in persons without glaucoma during dobutamine stress echocardiography causes pupillary dilation.

Methods And Results: Out of 144 patients without a history of glaucoma referred for DSE for clinical indications, 105 patients received intravenous atropine doses ranging from 0.

Dietary sodium estimation methods: accuracy and limitations of old and new methods in individuals at high cardiovascular risk.

Objective: Accurate and easy to use methods for dietary Na intake estimation in population level are lacking. We aimed at (i) estimating the mean Na intake in the group level using a variety of dietary methods (DM) and urinary methods (UM) and correlating them with 24-h urine collection (24UCol) and (ii) improving the accuracy of the existing DM.

Design: The most common DM (three 24-h dietary recalls (24DR) and FFQ) and UM (24UCol and spot urine collection using common equations) were applied.

Mock circulatory loops used for testing cardiac assist devices: A review of computational and experimental models.

Heart failure is a major health risk, and with limited availability of donor organs, there is an increasing need for developing cardiac assist devices (CADs). Mock circulatory loops (MCL) are an important in-vitro test platform for CAD's performance assessment and optimisation. The MCL is a lumped parameter model constructed out of hydraulic and mechanical components aiming to simulate the native cardiovascular system (CVS) as closely as possible.

Molecular Insights in Atrial Fibrillation Pathogenesis and Therapeutics: A Narrative Review.

The prevalence of atrial fibrillation (AF) is bound to increase globally in the following years, affecting the quality of life of millions of people, increasing mortality and morbidity, and beleaguering health care systems. Increasingly effective therapeutic options against AF are the constantly evolving electroanatomic substrate mapping systems of the left atrium (LA) and ablation catheter technologies. Yet, a prerequisite for better long-term success rates is the understanding of AF pathogenesis and maintenance.

CYP1A2 polymorphisms modify the association of habitual coffee consumption with appetite, macronutrient intake, and body mass index: results from an observational cohort and a cross-over randomized study.

Background/objectives: Evidence regarding the influence of coffee on appetite and weight control is equivocal and the influence of covariates, such as genetic variation in caffeine metabolism, remains unknown. Herein, we addressed the novel hypothesis that genetic variation in CYP1A2, a gene responsible for more than 95% of caffeine metabolism, differentially impacts the association of coffee consumption with appetite and BMI among individuals with different genetic predispositions to obesity.

Subjects/methods: A cross-over randomized intervention study involving 18 volunteers assessed the effects of coffee consumption on dietary intake, appetite, and levels of the appetite-controlling hormones asprosin and leptin.
