Thrombotic complications in pregnancy: a case-based review of the evidence

Pregnancy is a prothrombotic state due to an estrogen-driven shift in the coagulation system, increased venous stasis, and external restriction of blood flow caused by the gravid uterus. Venous thromboembolism (VTE) is a leading cause of morbidity and mortality in pregnancy. Preventing, recognizing, and treating thrombosis in pregnancy, as well as the postpartum period, often challenges decision making in the clinical setting. In early pregnancy, guidance with respects to thrombophilia testing and anticoagulation in increasing the likelihood of live birth among patients with recurrent miscarriages is evolving. This review explores emerging data that support clinical decision making in thrombosis care in women with common thrombotic complications in pregnancy. The first case outlines VTE diagnosis in pregnancy, initial anticoagulation management, management around delivery and postpartum, and subsequent long-term anticoagulation treatment. The second case examines testing for inherited and acquired thrombophilia in the setting of recurrent miscarriage and the management of obstetric antiphospholipid syndrome. Lastly, the third case reviews VTE risk assessment and prevention in pregnancy and the postpartum period, as well as duration and dose of postpartum thromboprophylaxis. Review of these common clinical scenarios surrounding thrombotic complications in pregnancy demonstrates recent advances in high-quality data, current gaps in knowledge, and variation in expert opinion. Ultimately, multidisciplinary discussion and teamwork remain key to optimal, safe care. Clinicians must prioritize collaborative, high-quality trials and prospective clinical management studies to better understand and define best practice in this population.

Debt, economic growth and threshold effects: Evidence from developing countries

PurposeMost empirical papers on threshold effects between debt and growth focus on developed countries or a mix of developing and developed economies, often using public debt. Evidence for developing economies is inconclusive, as is the analysis of other threshold effects such as those probably caused by the level of relative development or the repayment capacity. The objective of this study was to examine threshold effects for developing economies, including external and total debt, and identify them in the debt-growth relation considering three determinants: debt itself, initial real Gross Domestic Product (GDP) per capita and debt to exports ratio.Design/methodology/approachWe used a panel threshold regression model (PTRM) and a dynamic panel threshold model (DPTM) for a sample of 47 developing countries from 1970 to 2019.FindingsWe found (1) no evidence of threshold effects applying total debt as a threshold variable; (2) one critical value for external debt of 42.32% (using PTRM) and 67.11% (using DPTM), above which this factor is detrimental to growth; (3) two turning points for initial GDP as a threshold variable, where total and external debt positively affects growth at a very low initial GDP, it becomes nonsignificant between critical values, and it negatively influences growth above the second threshold; (4) one critical value for external debt to exports using PTRM and DPTM, below which external debt positively affects growth and negatively above it.Originality/valueThe outcome suggests that only poorer economies can leverage credits. The level of the threshold for the debt to exports ratio is higher than that found in previous literature, implying that the external restriction could be less relevant in recent periods. However, the threshold for the external debt-to-GDP ratio is lower compared to previous evidence.

Automatic medical term extraction from Vietnamese clinical texts

Abstract In this paper, we propose the first method for automatic Vietnamese medical term discovery and extraction from clinical texts. The method combines linguistic filtering based on our defined open patterns with nested term extraction and statistical ranking using C-value. It does not require annotated corpora, external data resources, parameter settings, or term length restriction. Beside its specialty in handling Vietnamese medical terms, another novelty is that it uses Pointwise Mutual Information to split nested terms and the disjunctive acceptance condition to extract them. Evaluated on real Vietnamese electronic medical records, it achieves a precision of about 74% and recall of about 92% and is proved stably effective with small datasets. It outperforms the previous works in the same category of not using annotated corpora and external data resources. Our method and empirical evaluation analysis can lay a foundation for further research and development in Vietnamese medical term discovery and extraction.

Arthroscopic Subscapularis Augmentation Using the Long Head of the Biceps Tendon for Anterior Shoulder Instability

The limitations of transferring the coracoid process along with the conjoined tendon are coracoacromial arch damage, technical difficulty, and nerve injury. The long head of the biceps tendon (LHBT) proximal transposition technique has a weaker sling effect and a risk of nerve injury. The arthroscopic subscapularis augmentation technique may have risks of shoulder external rotation restriction and subscapularis transection. Herein, we introduce an arthroscopic technique for the transfer of the LHBT for subscapularis augmentation to address these risks. Indications of this technique were patients younger than 45 years of age who engage in competitive sports, require forceful external rotation and abduction, have a related capsule-ligament insufficiency, and have a glenoid bone loss <25%. The steps include detaching the LHBT at the upper edge of the pectoralis major, transecting and braiding the LHBT, establishing a scapular tunnel, placing a guide suture through the upper third of the subscapular and scapular tunnel, passing the LHBT through the established tunnels, and fixating the LHBT. This technique achieves stability of the anterior shoulder by transecting and transferring the distal end of the LHBT to press on the upper third of the subscapularis muscle.

Research on Dynamic Community Detection Method Based on an Improved Pity Beetle Algorithm

In the last decade, community detection in dynamic networks has received increasing attention, because it can not only uncover the community structure of the network at any time but also reveal the regularity of dynamic networks evolution. Although methods based on the framework of evolutionary clustering are promising for dynamic community detection, there is still room for further improvement in the snapshot quality and the temporal cost. In this study, a dynamic community detection algorithm based on optional pathway guide pity beetle algorithm (DYN-OPGPBA), which is a novel dynamic community detection method based on the framework of evolutionary clustering, is proposed. We propose an improved PBA for community detection of the network at the first time step, including a discrete search strategy based on adjacent nodes, a closeness-based community modification strategy and a crowded community split strategy. Compared with many representative static community detection methods, the proposed method has some superior detection accuracy. A neighbour vector competition-based individual update strategy and an external population size restriction mechanism are also proposed for community detection at subsequent time steps. Results show that DYN-OPGPBA has a better balance between snapshot quality and temporal cost than two representative dynamic community detection methods.

Generation Mechanism of Corporate Online Public Opinion Hotness Based on Multicase Qualitative Comparative Analysis

Based on the actor network theory, this paper collects 20 representative corporate public opinion data through microblogs, uses the qualitative comparative analysis method to analyze these typical cases from the configuration perspective, identifies the elements and condition combination paths of corporate online public opinion hotness generation from four dimensions: enterprises, netizens, media, and government, and explores the generation mechanism of corporate network public opinion hotness. The results show three modes with high hotness of corporate network public opinion generation, which are internal and external linkage, internal leading, and external restriction. The public opinion hotness generation modes of consumers’ rights and interests and managers’ problems are different. Therefore, different measures should be taken to reduce the hotness of negative public opinion for different causes of corporate public opinion. Based on this, this paper puts forward some guidance suggestions, including strengthening the identification and contact with opinion leaders, strengthening the cooperation with the government and authoritative media, and strengthening the feedback response level of corporate network public opinion. This study helps to prevent and resolve public opinion crisis and provides reference for corporate public opinion governance.

HOW TO JUSTIFY MANDATORY ELECTORAL QUOTAS: A POLITICAL EGALITARIAN APPROACH

ABSTRACTThis paper offers a novel substantive justification for mandatory electoral quotas—e.g., gender or racial quotas—and a new methodological approach to their justification. Substantively, I argue for a political egalitarian account of electoral quotas. Methodologically, based on this account and a political egalitarian grounding of political participatory rights, I offer an alternative to the External Restriction Approach to the justification of electoral quotas. The External Restriction Approach sees electoral quotas as at best justified restrictions on political participatory rights. I argue for the Internal Restriction Approach instead, which can justify electoral quotas by specifying the pro tanto scope of political participatory rights rather than by justifying restrictions on the pro tanto scope of these rights. On this approach, adequately set electoral quotas do not even conflict with and are not balanced against political participatory rights, while electoral quotas—when justified—are pro tanto required rather than merely permitted.

Openness processes and new subjectivities: Analysis of the Cuban case

AbstractMotivationPrevious studies of the external restrictions on Cuba have not linked it with political subjectivity. Its consideration allows us to make visible discourses and collective imaginations that help us understand the political and economic dynamics of this Caribbean country.PurposeThe article aims to identify the measures, financial flows, and subjectivities that should be projected in the future both to make this external restriction more flexible and long‐term economic growth sustainable.Methods and approachTo this end, it examines, from both a qualitative and quantitative approach, the interaction among the external constraint, openness processes, and subjectivities in the case of Cuba.FindingsHistorically, Cuba has aimed to mitigate the external constraint that has hampered its economic growth through balances of power and strategic alliances compatible with and reinforced by political subjectivity. However, when these alliances have been broken or have been insufficient to compensate for the scarcity of foreign exchange, opening processes that require new subjectivities have had to be adopted.Policy implicationsThe tension between established and emergent subjectivities will define the limits that any opening process in Cuba will face in the future.

The Economy Between Pandemics

This article analyzes the economic and social impact of the pandemic in Argentina. It begins with the macroeconomic crisis that the new government had to face in December 2019 and the degrees of freedom available to be able to carry out compensatory fiscal and monetary policies to alleviate the effects of the pandemic. The article also analyzes the impact of these compensatory measures, their limits and results. In particular, it reviews the global impact of the pandemic, the different types of response at the international level and the asymmetry of the global recovery, in addition to evaluating different scenarios and their impact in Argentina and other developing countries. Finally, it also studies the temporary and permanent changes that the pandemic causes at the global level and suggests policy alternatives to avoid external restriction to face the crisis. It does so by laying the foundations for equitable development on the philosophical basis of Latin American structuralism and progressive thought, all within a new paradigmatic framework.

Muscles Affecting Minimum Toe Clearance.

The aim of this study was to investigate how the anterior and posterior muscles in the shank (Tibialis Anterior, Gastrocnemius Lateralis and Medialis), influence the level of minimum toe clearance (MTC). With aging, MTC deteriorates thus, greatly increasing the probability of falling or tripping. This could result in injury or even death. For this study, muscle activity retention taping (MART) was used on young adults, which is an accepted method of simulating a poor MTC—found in elderly gait. The subject's muscle activation was measured using surface electromyography (SEMG), and the kinematic parameters (MTC, knee and ankle joint angles) were measured using an optical motion capture system. Our results indicate that MART produces significant reductions in MTC (P < α), knee flexion (P < α) and ankle dorsiflexion (P < α), as expected. However, the muscle activity increased significantly, contrary to the expected result (elderly individuals should have lower muscle activity). This was due to the subject's muscle conditions (healthy and strong), hence the muscles worked harder to counteract the external restriction. Yet, the significant change in muscle activity (due to MART) proves that the shank muscles do play an important role in determining the level of MTC. The Tibialis Anterior had the highest overall muscle activation, making it the primary muscle active during the swing phase. With aging, the shank muscles (specifically the Tibialis Anterior) would weaken and stiffen, coupled with a reduced joint range of motion. Thus, ankle-drop would increase—leading to a reduction in MTC.

Artificial Intelligence and the Right to Data Protection

One way in which the law is often related to new technological developments is as an external restriction. Lawyers are frequently asked whether a new technology is compatible with the law. This implies an asymmetry between technology and the law. Technology appears dynamic, the law stable. We know, however, that this image of the relationship between technology and the law is skewed. The right to data protection itself is an innovative reaction to the law from the early days of mass computing and automated data processing. The paper explores how an essential aspect of AI-technologies, their lack of transparency, might support a different understanding of the right to data protection. From this different perspective, the right to data protection is not regarded as a fundamental right of its own but rather as a doctrinal enhancement of each fundamental right against the abstract dangers of digital data collection and processing. This understanding of the right to data protection shifts the perspective from the individual data processing operation to the data processing system and the abstract dangers connected with it. The systems would not be measured by how they can avoid or justify the processing of some personal data but by the effectiveness of the mechanisms employed to avert the abstract dangers associated with a specific system. This shift in perspective should also allow an assessment of AI-systems despite their lack of transparency.

The influence of parents on childhood weight status: relation with eating behaviour

AbstractProper dietary habits and behaviours are at the heart of maintaining an appropriate nutritional status, an adequate body mass and, as such, avoiding obesity and/ or its comorbidities. A child's diet is highly influenced by the home food environment and upbringing. The aim of the current study was to explore if and how parental feeding practices and eating behaviour are associated with child's eating behaviour and body mass index (BMI).In 226 Belgian adolescents (10–17y, 51% girls, 10% overweight and 14% underweight) and their parents, eating behaviour was assessed through the Dutch Eating Behaviour Questionnaire. Information on the parental feeding practices was obtained through the Child Feeding Questionnaire and the Comprehensive Feeding Practices Questionnaire. BMI was calculated based on standardised measurements of body height and body weight. Linear regression results, adjusted for age, sex and socioeconomic status, are described below.Regarding parental eating behaviour, parental external eating enhanced the child's external eating (β = 0.155,p = 0.022), parental restrained eating was associated negatively with the child's emotional (β = −0.214,p = 0.001) and external eating (β = −0.154,p = 0.022), but positively with its restrained eating (β = 0.149,p = 0.022) and BMI (β = 0.183,p = 0.005), while parental emotional eating had no influence. Concerning feeding practices, restriction of the child's access to food and food consumption monitoring, stimulated child's emotional (β = 0.174,p = 0.011; β = 0.173,p = 0.010) and restrained (β = 0.137,p = 0.041; β = 0.159,p = 0.015) eating, and showed a positive association with its BMI (β = 0.143,p = 0.033; β = 0.149,p = 0.023), while allowing the child to make own food choices reduced its external eating (β = −0.169,p = 0.012). Parental pressure to eat (mainly at mealtimes) decreased the child's restrained eating (β = −0.231,p &lt; 0.001) and was negatively associated with its BMI (β = −0.340,p &lt; 0.001). Moreover, child's BMI was inversely related to its external eating (β = −0.207,p = 0.002), but positively to its restrained eating (β = 0.0483,p &lt; 0.001) and to parental healthy modelling (β = 0.192,p = 0.003), involving the child (β = 0.223,p = 0.001) and creating a favourable food environment (β = 0.162,p = 0.013).Our results confirm the parents' crucial role in the development of their offspring's dietary habits. Mainly parental external eating, restriction and monitoring of the child's access to food have an unfavourable effect, while allowing child's own food choices and parental restrained eating seem beneficial. Rather unexpected associations between healthy food environment, modelling and child involvement with child's BMI might lie in causal dependencies. A longitudinal investigation could further elucidate the reasons for these observations. We recommend that policies and educational programmes on healthy diet and eating behaviour target not only schools and children, but also parents.

Validation of ECG-derived heart rate recordings in Atlantic cod (Gadus morhua L.) with an implantable data logging system

BackgroundArchival tags have been used on fish for a number of years to measure temperature, pressure and salinity, among other parameters. Measurements of heart rate in fish can be used in a wide variety of biological and ecological studies, e.g., for evaluating short- and long-term effects of stressful conditions involved with fishing and farming practices, or events that are non-related to human activity, such as predator–prey interactions. Furthermore, if a relationship between temperature, heart rate and metabolic rate has been established there are potentials to establish long-term bioenergy models that include seasonal effects on feeding, locomotion, spawning and migration. However, heart-rate measurements in fish have been difficult to conduct in the wild due to lack of commercial availability, large size of the recording systems, difficulties with proper placement of external electrodes and restriction in setup with external systems. This work presents a validation of a commercial ECG (Electrocardiogram)-derived heart rate data logger on farmed Atlantic cod. This validation focuses on assessing the logger’s signal processing algorithm and recording quality.ResultsThe eight fish studied showed both individual periodical variation, as well as individual baseline variation of the heart rate during the experimental period. Mean heart rate ranged from 29.9 ± 6.3 to 48.3 ± 4.9 bpm, at 10.2 ± 0.1 °C. This is comparable with previous research on Atlantic cod. The loggers were set up to record heart rate and temperature every 5 min and to store the ECG records used to calculate the heart rate every 30 min. The quality index (QI), which is an algorithmic assigned value of the quality of the ECG, was used to filter the data set eliminating a total of 21,643 measurements (19% of the recorded heart rate data). It was possible to manually calculate 18,490 out of 19,042 ECG records (97%).ConclusionsThis study presented a validation of using a commercial implantable data logging device in Atlantic cod that records ECG, and can calculate both heart rate, and a novel quality index for the ECG record with an on-board algorithm.

Effect of Inhaled Nebulized Furosemide (40 and 120 mg) on Breathlessness during Exercise in the Presence of External Thoracic Restriction in Healthy Men.

Inhalation of nebulized furosemide has been shown to alleviate breathlessness provoked experimentally in health and disease; however, it remains unclear whether the efficacy of nebulized furosemide on breathlessness is dose-dependent. We tested the hypothesis that inhaled nebulized furosemide would be associated with a dose-dependent relief of breathlessness during exercise testing in the setting of abnormal restrictive constraints on tidal volume (VT) expansion. In a randomized, double-blind, crossover study, 24 healthy men aged 25.3 ± 1.2 years (mean ± SE) completed a symptom-limited constant-load cycle endurance exercise test in the setting of external thoracic restriction via chest wall strapping to reduce vital capacity by ~20% following single-dose inhalation nebulized furosemide (40 and 120 mg) and 0.9% saline. Compared with 0.9% saline, neither 40 nor 120 mg of inhaled nebulized furosemide had an effect on ratings of perceived breathlessness during exercise or an effect on cardiometabolic, ventilatory, breathing pattern, or dynamic operating lung volume responses during exercise. Urine production rate, the percentage of participants reporting an “urge to urinate” and the intensity of perceived “urge to urinate” were all significantly greater after inhaling the 120 mg furosemide solution compared with both 0.9% saline and 40 mg furosemide solutions. We concluded that, under the experimental conditions of this study, inhalation of nebulized furosemide at doses of 40 and 120 mg did not alleviate breathlessness during exercise in healthy men.

Latin American Structuralism and Current Financialization

In this article, we attempt to update the understanding of the external constraint in Latin America by examining the recent history of the region through the analytical framework of Karl Polanyi in The Great Transformation. As we argue, the greatest force behind today’s external restriction is the financial sector, much as it was a century ago. To reinforce this hypothesis, we provide the reader with relatively new historical material and with arguments made by scholars from diverse backgrounds. Taking into consideration the political and economic structures of Latin America, we argue that the international connections between the elite of the center and the periphery remain the key aspect in understanding today’s complex reality.

Quantified Self, Freedom, and the GDPR

By Minke D. Reijneveld. The General Data Protection Regulation (GDPR) will be applied from May 2018. One of the many new societal developments it has to deal with is the Quantified Self (QS). This concerns data that are collected about a person by apps that aim to improve his or her life. This article answers the question to what extent the tools and assumptions that underlie the creation of QS influence an individual’s freedom and to what extent the GDPR can contribute to the protection of this freedom. The article finds that QS can restrict an individual’s internal and external freedom. It suggests that everybody should meet a certain standard or group norm, which influences the choices individuals make. This is an internal restriction of freedom, which is largely unknown. A more familiar problem is the external restriction of freedom. This happens when data are analysed by the QS app or by third parties. They can make assumptions about a person on the basis of these data, which influences the possible options for an individual. The GDPR does protect certain elements of external freedom better than the EDPD. This mainly has to do with the rules related to data about health, and more stringent rules in general. The GDPR does not protect the internal aspect of freedom, although the possible risks of this internal restriction can be very serious.

Message-related effects on consumer switching when the preferred product is out of stock

PurposeThis paper aims to investigate the effect of retailers’ consumer communications in prompting the choice of an in-stock alternative to an out-of-stock first-choice product.Design/methodology/approachFour between-subjects experiments assessed the extent to which the likelihood of a retail customer switching to a similarly-priced alternative when a first choice was out-of-stock was affected by messages concerning stockout status (Studies 1a and 1b). They further examined the interaction effects on participants’ preference of messages comparing the available versus unavailable options and stating stockout status (Study 2) and those giving information on the reasons for the stockout and on its status (Study 3).FindingsParticipants maintained their original preference for an out-of-stock product unless an external restriction on choice prompted them to forsake it or they perceived a strong reason to opt for an in-stock alternative. There was a greater tendency to switch if the alternative offered a potential “gain” or the reasons given for a stockout were irrelevant to product performance, whether the participant was expecting imminent re-stocking. Switching was triggered when the available alternative was directly comparable to the original or the retailer’s explanation related to an attribute judged trivial, but only if short supply was expected to continue.Originality/valueThe studies add to current understanding of how shoppers respond to unavailability of a first-choice product by examining the effect on switching behavior of messages about the stockout situation that are communicated deliberately or inadvertently by retailers.

Research on the E-commerce Business New Pattern from Perspectives of SWOT and Customer Relationship Management

In this paper, we conduct research on E-commerce business new pattern from perspectives of SWOT and customer relationship management. E-commerce and linkage development of that industrial cluster is not yet clear, but according to the relationship between the two and interaction, we can think e-commerce and linkage development of industrial cluster is to point to in the process of development with each other, through a variety of role and depend on the each other, coordinate with each other, promote each other's joint, the dynamic development model. E-commerce is a huge and complicated social economic and technical system. The operation of a system to internal conditions and that external environment influence and restriction, so the electronic commerce risk is objective existence and e-commerce information ecosystem and the environment interaction, mutual influence, and as between system by admitting the members and update the information subject, guarantee the realization of system functions. For this initialized goal, we propose the novel perspective on the basic issues that will promote the development of the related industries.

Exchange rate risks in a small open economy

PurposeThis study aims to analyze exchange rate risks and the choice of exchange rate policies in a small open economy indebted in foreign currency, incorporating the financial accelerator mechanism.Design/methodology/approachTo examine discussions on the fear of floating, this study develops a dynamic stochastic general equilibrium model in which a small open economy model has an open economy financial accelerator mechanism as the external borrowing restriction. The author then compares and analyzes the macroeconomic dynamics in response to an exchange rate shock under different exchange rate systems.FindingsThe most interesting finding is that the currency peg for a foreign currency used in borrowing is more efficient than the trade-weighted currency basket policy, regardless of trade openness or trade share.Practical implicationsThe result implies that in discussions on the fear of floating, more attention needs to be paid to exchange rate risks in finance. It also suggests that exchange rate policy used to mitigate exchange rate risks in finance stabilizes macroeconomic volatility more efficiently.Originality/valueThe paper provides an answer to the question: which is the more serious problem in the fear of floating and to what would the regime be anchored.

Larangan Aktivitas Jemaat Ahmadiyah Indonesia (JAI) di Jawa Timur dalam Perspektif External Protection dan Internal Restriction Will Kymlicka

In order to protect Ahmadiyah in East Java, the executive body of East Java Province has issued a Degree No. 188/94/KPTS/013/2011 regarding the prohibition of the Ahmadi’s activity in east java. However, it becomes controversial. On one hand, it is considered protecting minority’s right, but on the other hand, it also weakens the position of Ahmadiyah toward majority’s group outside Ahmadiyah. One implication of the degree is the loss of the primer rights of the group in worshiping their belief in accordance with their faith. Combining Kymlicka’s external protection and internal restriction, this article attempts to analyze the implication from the government degree. The basic assumption of this article is that the country is incapable to protect the existence of minority group, Ahmadiyah. The finding shows that the Government of East Java cannot protect the principle rights of Ahmadiyah, especially the right to worship based on their religious belief. As a response to this restriction, Ahmadiyah has applied an internal restriction towards their members that protect themselves from the majority. However, this restriction does not have a penalty so it is considered protecting individual rights of Ahmadiyah group.
