Occurrence and Classification of Cerebrovascular Events after Isolated Bioprosthetic Surgical Aortic Valve Replacement: A Competing Risk Analysis of the CAREAVR Study

ABSTRACT Background: The long-term incidence of stroke and the proportion of cardioembolic events after bioprosthetic surgical aortic valve replacement (SAVR) remain largely unknown. Methods: The CAREAVR study sought to assess the rate of stroke and transient ischemic attack (TIA) in patients who underwent isolated surgical aortic valve replacement with a bioprosthesis at four Finnish university hospitals between 2002 and 2014. Data was collected retrospectively and included 721 patients. Median follow-up time was 4.8 [3.0–7.0] years. Results: At 5 years, freedom from stroke was 89.0%, from TIA 94.1%, and from stroke and TIA 83.7%. The median time between index procedure and stroke or TIA was 1.7 years [29 days–3.9 years]. Stroke was of cardioembolic origin in 44.4% of patients. In multivariable competing risk analysis, increased age (HR 1.03, 95%CI 1.00–1.06, p = 0.022), previous stroke or TIA (HR 1.75, 95%CI 1.14–2.70, p = 0.010), New York Heart Association (NYHA) class III or more (HR 1.51, 95%CI 1.01–2.24, p = 0.044) and insulin treatment at discharge (HR 1.20, 95%CI 1.09–3.64, p = 0.024) were independent predictors of stroke or TIA. Cerebrovascular events occurred in 47.2% of patients with ongoing anticoagulation therapy. Conclusion: In this study, the incidence of stroke in the early postoperative period after bioprosthetic SAVR was higher than previously documented. Almost half of strokes were of cardioembolic etiology. These findings highlight the need for the better prevention strategies for cardioembolic events after bioprosthetic SAVR.
Physicochemical parameters of liquid and spray-dried honey of stingless bee Scaptotrigona pectoralis

Mexican stingless bee honey was already used in ancient civilizations for food and medicinal purposes. In this study, certain physical and chemical parameters of honey [liquid and powder (spray-dried)] produced by the stingless bee Scaptotrigona pectoralis from Yucatan, Mexico, were determined. Measured parameters in liquid honey were as follows: color (85.0 mm Pfund), moisture (25%), pH (3.6), acidity (116.0 meq kg−1), ash (0.25%), hydroxymethylfurfural (43.0 mg kg−1), invertase activity (22.0 IN) and reducing sugars [38.0 g (10 kg−1)]. Of nineteen volatiles compounds positively identified, p-anisaldehyde was found as the major compound. The antioxidant activity was evaluated by using the methods ABTS•+ [37.0 µmol ET (10 kg−1)] and DPPH [3.50 µmol ET 10 kg−1]. Polyphenols content was 23.0 mg EAG 10 kg−1. Honey antioxidant activities were by ABTS•+ [37.0 µmol ET (10 kg−1)] and DPPH [3.5 µmol ET (10 kg−1)]. Polyphenols content was 23.0 mg EAG (10 kg−1). On the other hand, the spray-dried honey of S. pectoralis, presented high hygroscopicity [22.0 g (10 kg−1)], good solubility (265 s), low density (0.34 g ml−1) and good volatiles retention (77%). The antioxidant activity of the honey powder was higher [51 µmol ET (10 kg−1)] (ABTS•+ method) than in the liquid honey. The results show new information about the composition of the liquid honey and honey powder, which helps to assess their qualities. Further, the spray-drying process could be an alternative to preserve and even improve the antioxidant activity of S. pectoralis honey probably due to enrichment of antioxidant compounds in the powder.
Investor Behavior and Asset Pricing Anomalies

This dissertation investigates the behavior of investor classes and their effect on returns, liquidity, and informational efficiency around momentum-related asset pricing anomalies. Chapter 1 explores the role of household and institutional investor net buying in amplifying and suppressing the returns to momentum-related anomalies. Using trade level data from the NASDAQ OMXH (Finland), trades made by households and institutional investors are identified. Using this data, we show that households slow the integration of positive information into stock prices, resulting in an increase in long run non-mean-reverting momentum. Winner stocks heavily purchased by households in the momentum formation period subsequently outperform winner stocks heavily purchased by institutions during the formation period. The enhanced momentum returns appear to be driven by the tendency of households to insufficiently incorporate news into prices. On the other hand, institutional buying appears to drive prices closer to their fundamental value. Chapter 2 investigates the cause of volume spikes and post-event returns observed at the 52 week high (George and Hwang, 2004; Huddart et al.,
Future Interactions Between Sea Level Rise, Tides, and Storm Surges in the World's Largest Urban Area

The Pearl River Delta contains the world's largest urban area in both size and population. It is a low‐lying flood‐prone coastal environment exposed to sea level rise (SLR) and extreme water levels caused by typhoons. A Finite Volume Community Ocean Model implementation for the South China Sea and the Pearl River Delta is used to understand how future SLR, tides, and typhoon storm surges will interact and affect coastal inundation. The SLR signal and extreme surge levels provide the major contributions to flooding; however, amplification of tides could exceed 0.5 m for 2.1 m SLR and should be considered when planning future coastal defences. On the other hand, if typhoons like Hato or Mangkhut, the latest and strongest ones hitting the area, were to happen in the future, a surge level reduction up to 0.5 m could be expected in coastal areas.
Highly miniaturized wideband 3‐dB branch‐line hybrid with second harmonic‐suppression

In this article, a highly miniaturized second harmonic suppressed 3‐dB branch‐line hybrid (BLH) with wideband performance is developed by employing a novel transmission‐line architecture (TLA). The proposed architecture consists of a coupled‐line, a series microstrip‐line and two open‐ended stubs. The even‐odd mode technique is used to formulate the required design equations. In order to reduce the size of the BLH, the internal areas between the branches are properly utilized for accommodating the proposed TLA structures with parameter values calculated using the derived formulas. To demonstrate this technique, a wideband three‐section BLH operating at 0.9 GHz is designed and fabricated. The measurement results show the proposed technique reduces the total circuit‐area of the BLH by 90.24% compared to the traditional three‐section hybrid while maintaining a fractional bandwidth greater than 53%. In addition, the second harmonic is eliminated utilizing the spurious response produced by the open‐ended stubs.
Evolution of Denmark Strait Overflow Cyclones and Their Relationship to Overflow Surges

Mesoscale features present at the Denmark Strait sill regularly enhance the volume transport of the Denmark Strait overflow (DSO). They are important for the Atlantic Meridional Overturning Circulation and ultimately, for the global climate system. Using a realistic numerical model, we find new evidence of the causal relationship between overflow surges (i.e., mesoscale features associated with high‐transport events) and DSO cyclones observed downstream. Most of the cyclones form at the Denmark Strait sill during overflow surges and, because of potential vorticity conservation and stretching of the water column, grow as they move equatorward. A fraction of the cyclones form downstream of the sill, when anticyclonic vortices formed during high‐transport events start collapsing. Regardless of their formation mechanism, DSO cyclones weaken starting roughly 150 km downstream of the sill, and potential vorticity is only materially conserved during the growth phase.
Effects of Short-Term Storage or Pre-Storage Heating of Hatching Eggs from Young Broiler Breeder Flock before Incubation on Hatching Parameters and Chick Quality

This study was conducted to evaluate the effects of short-term storage (four days) or pre-storage heating of hatching eggs from young Ross broiler breeding flocks (28 week old) on hatching parameters and chick quality. In total, 1350 hatching eggs of 1 d and 4 d of laid were individually numbered and distributed three treatments, named as NS (eggs that were not stored), S (eggs that were stored for four days before incubation) and HS (eggs that were heated at 37.7 °C and a relative humidity of 60% for 24 h and then stored for three days before incubation). The HS treatment increased the hatchabilities of set and fertil eggs compared to the NS and S treatments, whereas the S decreased the these variables compared to the NS treatment. The embrionic mortality in the HS eggs was lower than those in the NS and S eggs. The rate of discarded chicks was higher in the S group than in the HS group. The chick weight in the NS treatment was higher than those in the S and HS treatments. In conclusion, the pre-storage heating of hatching eggs from young broiler breeder flock positively affected hatchability without chick weight and quality.
Hybridity, Transparency, Structured Freedom and Flipped Engagement – an Example of Networked Learning Pedagogy

In this paper, we contribute to current discussions of what constitutes the field of networked learning as a research domain and what makes networked learning particularly relevant and distinct within the broader landscape of digital technology in higher education. We enter this dialogue through discussing and reflecting on a hybrid learning design for a 10-ECTS module that builds on a Networked Learning Pedagogy. The purpose of our discussions is to elicit tensions and contradictions that surface when students are confronted with a networked learning pedagogy. We discuss the module in relation to ideas of networked learning pedagogy, present four pedagogical principles underpinning the module, and we draw out interesting tensions and contradictions that have emerged. Following this, we use the discussions to feed into the ongoing dialogue of ‘what is networked learning’, and we discuss how networked learning can contribute to practice and policy in higher education through developing practice.
Ecosystem services in certified and non-certified coffee agroforestry systems in Costa Rica

ABSTRACT Coffee agroforestry systems provide ecosystem services, the quality of which depends on the management carried out by coffee farmers. This study evaluated the provision of four ecosystem services (maintaining habitats, improving water quality, erosion control, and carbon stocks) on certified and non-certified coffee farms. We studied 30 coffee agroforestry systems located in Turrialba and Orosi using three different certification systems (Utz-Rainforest Alliance, Nespresso, Organic) and some without certification. Certified coffee agroforestry systems provide more ecosystem services than non-certified ones; however, on some non-certified coffee farms, different activities that provide ecosystem services were performed. Of the coffee farms evaluated, certified Organic farms had the highest conservation activities.

On Social Identity

This chapter begins to explore what it means to have a socially undocumented identity by means of establishing what asocial identities are. It engages the respective metaphysical accounts of social identity of Linda Martín Alcoff and Pierre Bourdieu, both of which focus, albeit in different ways, on the embodied aspects of certain social identities. It adopts an account of social identity that understands such identities—particularly those that are race, gender and class-based—to be real, embodied sites of hermeneutical horizons. The goal is to develop a theory of socially undocumented identity that will prove useful for dismantling the sorts of institutions, thinking, and rhetoric that serve to brand and constrain unjustly a subset of the population as so-called “illegals. ”
Atrial Fibrillation Management in Emergency Departments: A New Protocol Assessment

Non-valvular atrial fibrillation (AF) is the most frequently encountered heart rhythm disorder in emergency medicine. It is at the origin of one third of hospitalizations for arrhythmia [1, 2]. Its prevalence is about 1.5 to 2% of the general population and increases quickly with age, reaching over 10% in 80-year-old subjects and over 20% after 90 years of age [3]. Death rates are doubled by AF, due to an increased risk of thromboembolic [4-7] and hemodynamic complications [1-3] and an increased risk of hospitalization [1]. Because emergency physicians are often the first to manage these patients, we easily understand the challenge of optimal management of early discovered atrial fibrillation in emergency departments (ED).
A cross-sectional study on the prevalence of diabetes mellitus and its association with various sociodemographic factors in Surendranagar city, Gujarat

Background: Type 2 diabetes (formerly called non-insulin-dependent or adult-onset) results from the bodys ineffective use of insulin and is responsible for 90% of people with diabetes around the world. Healthy diet, regular physical activity, maintaining a normal body weight, and avoiding tobacco use can prevent or delay the onset of Type 2 diabetes. Diabetes increases the risk of heart disease and stroke. 50% of people with diabetes die of cardiovascular disease. Objectives: The objectives of this study were to know the prevalence of diagnosed case of diabetes mellitus among adults and its association with various sociodemographic factors. Materials and Methods: A cross-sectional study was done; the total sample size was 3600. Of total 14 wards, 6 wards were selected by simple random sampling; out of each selected ward, 600 people were taken by house-to-house visit. Results: The prevalence of diagnosed cases of diabetes was 4.94% in the study population. The prevalence of diabetes increased significantly with increasing age. There was no significant association between gender, religion, types of family, dietary pattern, and the prevalence of diabetes. The prevalence of diabetes was higher among lower socioeconomic class and illiterate. Conclusion: People suffering from diabetes should be informed by the treating doctors about regular checkups, dietary modifications, exercise, foot care, regular treatment, early notice of complications, etc., which will go a long way in the management and quality of life of the patient.
Mitochondrial event localiser (MEL) to quantitativelydescribe fission, fusion and depolarisation in the three-dimensional space

Mitochondrial fission and fusion play an important role not only in maintaining mitochondrial homeostasis but also in preserving overall cellular viability. However, quantitative analysis based on the three-dimensional localisation of these highly dynamic mitochondrial events in the cellular context has not yet been accomplished. Moreover, it remains largely uncertain where in the mitochondrial network depolarisation is most likely to occur. We present the mitochondrial event localiser (MEL), a method that allows high-throughput, automated and deterministic localisation and quantification of mitochondrial fission, fusion and depolarisation events in large three-dimensional microscopy time-lapse sequences. In addition, MEL calculates the number of mitochondrial structures as well as their combined and average volume for each image frame in the time-lapse sequence. The mitochondrial event locations can subsequently be visualised by superposition onto the fluorescence micrograph z-stack. We apply MEL to both control samples as well as cells that have been treated with hydroxychloroquine sulphate (HCQ) and observe that fission and fusion events mostly occur around the terminal branches of the mitochondrial network, with few events detected in the strongly networked areas such as the perinuclear region. Depolarisation was most abundant in the HCQ treated samples, with the majority of the depolarisation events occurring in the cell periphery.
