Are portable ankle brachial pressure index measurement devices suitable for hypertension screening?
Authors: Janus Justyna , Nicholls Jennifer K. , Pallett Edward , Bown Matthew , Chung Emma M. L.
Published: March 2023

Objective

In a large-scale population cardiovascular screening programme, peripheral artery disease (PAD) and hypertension would ideally be rapidly assessed using a single device. The ankle-brachial pressure index (ABPI) is calculated by comparing the ankle and brachial blood pressure (BP). However, it is currently unclear whether brachial BP measurements provided by automated PAD screening systems are sufficiently accurate for simultaneous hypertension screening.

Methods

Two portable PAD screening devices, the MESI ABPI MD and Huntleigh’s Dopplex ABIlity, were evaluated following the European Society of Hypertension International Protocol (ESH-IP) Revision 2010 using a mercury-free sphygmomanometer as a reference device.

Results

On average, the MESI slightly underestimated brachial systolic blood pressure (BP) with a bias and standard deviation (SD) of -3.5 (SD: 3.3) mmHg and diastolic BP with a bias of -1.5 (SD: 2.3) mmHg. For systolic BP estimates, the Dopplex was more accurate than the MESI with a lower bias of -0.5 (SD: 4.2) mmHg but less precise. The MESI successfully fulfilled all the requirements of the ESH-IP for hypertension screening. The Dopplex device failed the ESH-IP due to the absence of DBP measurements.

Conclusions

The MESI device appears to be suitable for simultaneous PAD and hypertension screening as part of a preventative care programme. Huntleigh’s Dopplex ABIlity failed to pass the ESH-IP validation test. Further clinical trials are underway to assess the use of the MESI for simultaneous screening for hypertension and PAD in a population screening setting.

La Marina alemana y la evacuación de refugiados en la guerra civil española, 1936-1937
Authors: Gómez García Iñigo
Published: March 2023

En este artículo se abordará cómo la Marina de guerra alemana participó en la evacuación de miles de extranjeros que buscaban salir de España una vez comenzó la guerra civil. Con base en la documentación primaria alemana, se analizará el despliegue de las fuerzas navales germanas para tratar de entender su modus operandi, poniéndolo en contexto mediante la comparación de sus actividades con las evacuaciones llevadas a cabo por otras marinas en este mismo espacio. Así se mostrará cómo durante el desarrollo de sus operaciones, la Marina alemana favoreció al bando sublevado, tanto por su política de evacuación como por las actividades paralelas que desempeñó durante los primeros meses de la guerra civil.
Extrema violencia contra civiles como método de guerra en España (1936-1939): Fotoperiodismo y doble potencial de la fotografía
Authors: Volkmar Ossa Natalie
Published: March 2023

Conforme a las tres violencias ejercidas contra la figura republicana durante la guerra en España (1936-1939), el fotoperiodismo desarrolló una contranarrativa al visibilizar los estragos de las masacres sobre la población civil. Si bien, la cobertura periodística realizada en la matanza de Badajoz y en el bombardeo a Gernika -ambos episodios paradigmas de los dos métodos de guerra ejercidos contra los republicanos- puso de manifiesto el doble potencial de la fotografía, y los usos dispares que los distintos actores hicieron de ella; hecho que nos plantea la necesidad de una relectura, más allá de lo que muestra el documento visual y su aparente carácter testimonial. Teniendo en cuenta el peligro latente en el manejo de la fotografía por parte del poder, el trabajo de los fotoperiodistas demostró su utilidad y valor social como instrumento de dignificación, denuncia y vehículo para la reconstrucción de una historia ocultada, tergiversada y silenciada.
La Oficina y la Comisión Interministerial para la Promoción de la Moda: la proyección internacional de la alta costura durante el Franquismo desarrollista
Authors: Gennaioli Daniele
Published: March 2023

El presente artículo ha de encuadrarse en el marco de los estudios acerca de las políticas de promoción de la moda española, impulsadas tras la Segunda Guerra Mundial. En la década de 1960, el gobierno franquista intentó reorganizar, desde una perspectiva institucional, el heterogéneo abanico de entidades llamadas a coordinar un sector crucial para la imagen del régimen en el extranjero: la alta costura. En el seno del Ministerio de Información y Turismo surgieron primero la Oficina de promoción de la moda, en 1965, y posteriormente la Comisión interministerial para la promoción de la moda, en 1967. Pese a que ambos organismos desempeñaron un papel relevante en el proceso de internacionalización de las principales firmas de Barcelona y Madrid, su fortuna crítica ha sido prácticamente nula en la historiografía contemporánea. A través de materiales de archivo inéditos, esta investigación se propone reconstruir la estructura orgánica y funcional de ambas instituciones.
Heroicidad, sabiduría y realeza en la edad mítica de China (II): rangos de ordenamiento y civilización
Authors: López Saco Julio
Published: March 2023

Algunas tradiciones míticas chinas, como la que se refiere a los Augustos y Soberanos, probable recuerdo de arcaicas jefaturas neolíticas o de grupos legendarios de antepasados predinásticos, son aprovechadas para establecer paradigmas didácticos aplicables a la política, el buen gobierno y a la moral de un gobernante muy idealizado. Deidades y héroes originales, salvadores y fundacionales, aunque humanizados, son concebidos como modelos y estereotipos ideales de perfección. Héroes, reyes y sabios míticos, ancestros culturales, espíritus ancestrales, son utilizados en la literatura confuciana como modelos prototípicos que estimulan, y a la par justifican, el modo ético y moral de conducirse en el gobierno del Estado y en la organización socio-familiar. En la taoísta, se emplean como paradigmas que sirven como medio de argumentar principios, conceptos y especulaciones de diversa consideración. Toda una serie de tales héroes y ancestros sirven de explicación de los inicios del tiempo histórico, empleándose con el objetivo de ensamblar un sistema unitario y centralizado asentado en aspectos metafísicos, mitológicos y religioso-morales.
Los límites éticos de la neuroeducación
Authors: Castillo Paloma
Published: March 2023

¿Cuáles son y dónde están los límites éticos de la neuroeducación? El artículo reflexiona sobre una cuestión necesaria para el devenir de los procesos cognitivos mediante la deliberación crítica, la delimitación de fronteras y la estimación del progreso. Su hilo argumental proyecta, por un lado, que el giro experimental podría poner en entredicho el objetivo ético y humanista de la educación; por otro lado, que una renuncia sistemática a los avances de las neurociencias supondría, igualmente, abandonar la búsqueda del florecimiento humano. Las humanidades solo no brindan el enfoque biopsicosocial desde el que hemos de entender nuestra autorrealización. Por ende, el primero de los límites que es origen de todos los demás surge dada una disyuntiva científico-humanista. Los nuevos confines a delimitar subyacen de las implicaciones neurocientíficas en sí mismas y de cómo estas se trasladan a la praxis escolar, si es que tuviesen validez en este campo. Aquí los neuromitos juegan un papel importante. Precisamente, la neuroética como ética aplicada o rama de la bioética recoge estos aspectos mediante la ética neuroeducativa y la neuroética educativa. En su rama fundamental, dicha disciplina abre el debate sobre la neuroeducación moral. Pero la posibilidad de reducir lo moral y todo lo que somos a nuestras bases neurales deriva en nuevos límites. Para superarlos, destaca el potencial de una simbiosis sociocultural y biológica con las nociones de ‘neurocultura’ y de ‘epigénesis proactiva’. Finalmente, el ensayo delibera sobre los límites más especulativos entre lo que somos y nuestras posibilidades para entenderlo en base al transhumanismo.

Confidence in Healthcare System vs Life Satisfaction
Authors: Chau Chun Yee
Published: March 2023

A large body of research has connected life satisfaction with health. However, there is a lack of research on the relationship between life satisfaction and one’s confidence level in the healthcare system. In this study, the main hypothesis was that these two variables are positively correlated. Also, it was hypothesized that satisfaction with personal health would serve as a moderator. By adopting the data from Gallup World Poll obtained in the year 2009, a multi-level model was conducted. The model was used to predict life satisfaction from confidence in the healthcare system, adjusting for income. Results significantly supported the main hypothesis, showing that individuals’ life satisfaction are likely to be higher when they have higher confidence in healthcare. However, the results did not support the hypothesis of the moderator, meaning that satisfaction with personal health does not moderate the relationship. The results findings could be used to encourage policymakers and healthcare providers to take measures in improving citizens’ confidence level in the healthcare system.

Authors: Katiwa Gabriel
Published: March 2023

This paper concentrates on using electric water heaters with the aim of demanding response. This is so as this method is considered most efficient when it comes to ensuring the safety and stabilization of power grids through the maintenance of balance between the demand and supply of the power grid. For this reason, the article investigates the overshoot temperature and the impact it has on demand response as well as to ensure the comfort and pricing variables as it happened in previous publications. The demand response process utilizing electric water heaters is explored as well as the impact of the physical parameters and the settings of the water heaters. In addition, a model is developed which puts into consideration the demand response requirements, the comfort of these water heater equipment, the power supply price in a simultaneous manner. Also, the effect of these factors on the end results of demand response is addressed. Experimental data is further used to demonstrate the efficiency of the suggested strategy.

A água é um recurso primordial à subsistência das formas de vida e para o qual a demanda tem crescido anualmente; assim, a proteção dos locais “produtores” de água, como nascentes e olhos d’água, tem elevada importância. Neste cenário, a crescente demanda por espaço tem avolumado a pressão sobre estes ambientes. Não obstante ser esta uma problemática crescente, raras são as ferramentas que permitem padronizar as análises hidrogeológicas da existência de mananciais hídricos, especialmente em áreas antropizadas. Neste sentido, o presente trabalho almeja, por meio da proposição de um roteiro técnico tripartite, trazer à luz uma metodologia que permita aos entes e entidades relacionados ao licenciamento ambiental e à gestão territorial segurança técnica no processo de tomada de decisão. O roteiro engloba técnicas e conhecimentos que devem ser considerados em uma análise de mananciais hídricos, roteirizando de forma ordenada e sistemática passos e informações imprescindíveis. A metodologia proposta é composta por três fases, caracterizadas pela construção de um modelo conceitual em cada uma delas. Mediante o proposto, espera-se trazer celeridade, uniformização e robustez às análises hidrogeológicas. Como fim, pretende-se contribuir na construção de orientações técnicas que resultem na preservação e proteção dos mananciais hídricos, defronte a pressão que estes ambientes sofrem.

Published: March 2023

We analyse nonlinear second-order differential equations in terms of algebraic properties by reducing a nonlinear partial differential equation to a nonlinear second-order ordinary differential equation via the point symmetry f(v)∂v. The eight Lie point symmetries obtained for the second-order ordinary differential equation is of maximal number and a representation of the sl(3,R) algebra. We extend this analysis to a more general nonlinear second-order differential equation and we obtain similar interesting algebraic properties.

Published: March 2023

Ethnobotanical exploration was undertaken to document the Wild edible plants (WEPs) utilised by the inhabitants of the Leh district. Traditionally exploited WEPs are an indispensable part of every household culinary. This place is known for its unique culture and cuisine which diversifies it from the rest of India. Pre-structured questionnaires, guided field visits, field examinations, and group discussions were conducted to gather ethnobotanical data. Detailed inquiries were made on the plant’s part used, time of collection and method of food preparation. In the present study, 40 wild consumable plants were documented, these belong to 18 families and spreads to 31 genera; out of which four are new records as wild food plants. They are Cotoneaster integerrimus, Dracocephalum heterophyllum, Astragalus frigidus, and Turritis glabra. Diverse use of wild leafy plants was observed and some of the most famous dishes are ‘Shangsho tsodma’ and ‘Kabra tsodma’ vegetables. The utilisation of wild plants helps enrich diet diversity and enhances the availability of green vegetables hence broadening food choices. Our study also reveals that the gathering of wild plants is confined to village people, shepherds, and farmers, and a majority of this knowledge exists in the memory of the elderly and these wild resources are under threat due to various anthropogenic activities. Therefore, the present finding highlights the value of these plants along with maintaining regional traditional knowledge and preserving the old ethnic traditional way of living and eating. Further, this information will provide baseline data to upcoming researchers dealing with nutrition and nutraceutical aspects. In addition, these wild plants are nutritionally rich and their consumption should be encouraged.
Kadaknath Chicken Meat Scope and Source of Animal Origin Nutrients for High Altitude Regions
Authors: . Swati , Bharti Vijay K. , Chaurasia O. P.
Published: March 2023

Leh-Ladakh falls in the category of a high-altitude region with low oxygen, low atmospheric pressure and lack of moisture in the air, thus rendering the climate harsh. Therefore, humans staying in this region need different diets, nutrient levels, and other health supplements compared to low-lander people to thrive under these stressful conditions. Chicken meat and eggs have high biological value proteins that play an important role in nutrient supply in human diets. Among them, Kadaknath chicken meat is very famous for its nutritious brown and greyish-black flesh. Its meat contains more protein, less cholesterol and less fat. Its flesh is also known for its various medicinal properties, so it is very popular among health-conscious people. However, fresh chicken production at high-altitude is very limited due to stressful conditions, making poultry rearing very difficult and uneconomical. Kadaknath is an Indian breed of chicken from the Jhabua region of Madhya Pradesh known for its hardy nature to thrive in any harsh environment. Therefore, the Kadaknath breed can be a good choice for high-altitude due to its hardy nature and disease-resistant ability. Hence, Kadaknath chicken meat can prove to be a superfood in high-altitude and such remote regions, especially during the acclimatization period. We have recently started working on the propagation of Kadaknath chicken among the farmers of Ladakh and evaluating their meat quality and medicinal value. The present review focuses on the scope of Kadaknath chicken at Leh-Ladakh under backyard farming, its acceptance, and the advantage of its meat in providing complete nutrition to human consumers.
Analysis of Pleated Discrete Pore Non Woven Layer Type Filter Element for Naval Applications

Published: March 2023

In naval applications generally, the pleated discrete pore non-woven layer filter element is used. Filters used for such applications require maximized filtration rate, lower pressure drop, higher permeability, effective pore size distribution and good filtration efficiency. In other most common wire mesh filter element types, the geometric parameters are well defined and can easily be modelled. In the case of non-woven layer filter elements the pores are arranged in a randomly distributed manner and the modelling becomes difficult. In this present study a new approach was contemplated for modelling the same. The fluid flow through the filter element is by percolation phenomenon. Using Darcy’s law approach, the pressure drop across the filter element for different flow rates, were found analytically by considering the flow resistance in axial, radial and circumferential directions. The theoretical prediction made by CFD analysis is correlated with actual model behaviour and a good degree of correlation is obtained which shows the efficacy of this method for wider use in similar application.

Published: March 2023

The urban military operating environment may offer favorable conditions for combat involving asymmetric actions or 4th generation warfare which includes the chemical, biological, radiological, or nuclear (CBRN) environment. The CBRN environment is characterized by threats and hazards capable of producing negative impacts to the operations. The detriment may be produced by intentional release of hazardous materials into the operational environment. This study deals with an environment deliberately contaminated by radioactive materials because of the activation of a radiological dispersive device (RDD). A computer simulation of the radioactive scenario was performed in order to produce useful information which in turn can be used to support decision-making. The main goal was to assess the risk of developing radio-induced solid cancer by studying the articulation between local environmental variables and a cognitive bias, the Dunning-Kruger effect. The findings highlight intuitive correlations between local atmospheric stability and cognitive bias affecting the threat level (radiation dose), the responsiveness and the perceived risk. The findings also allow us to infer that, especially in the military-operational context, the methodology proposed for the assessment of environment-human interactions may be decisive for correctly direct available resources, both human and material, reducing operational risk.
Simulation and Analysis of Electro Mechanical Actuator with Position Control
Authors: S Rengasamy , D Manamalli , R Ramaprabha
Published: March 2023

In recent times, Electro-Mechanical Actuator (EMA) is widely employed in various aerospace applications

because of its compactness, ease of maintenance, and cost efficiency. It attracts most of the researcher for simulation and performance analysis. It is very much important to study its control system behaviour. In general, EMA requires, three loop cascade control, but for aerospace application two loop cascade control is used for speed and position controls due to dynamic load changing requirement. Most research efforts on EMA system has used a transfer function model of all its subsystems. Nevertheless, this technique does not yield complete outcomes for analysing its performance. To analyse its performance and characteristics in dynamic condition, an experimental model is essential. In addition, this model needs to cater for analysing performance of different capacity EMA. The primary goal of this work is to simulate unique EMA model with position control using a practical data and analyse its performance. In this design, EMA is modelled by three-phase Brushless Direct Current (BLDC) motor, six-step commutation logic, a speed sensor (Tacho) and a position sensor using Linear Variable Differential Transformer (LVDT). Position and speed controls are handled by Proportional (P) and Proportional plus Integral (PI) controllers respectively. The process reaction curve method is used to tune the controllers. This tuning approach is adequate to enable accurate and robust speed and position control. This paper focus on the simulation and performance analysis of a practical EMA system with position and speed controls in matlab-simulink. The performance analysis results shows that simulated model characteristic is close to physical system and reliable.

In fluid dynamics analysis, one of the things to do is to perform numerical modeling validated on the resultsof experimentation. In numerical modeling of wind flow there are several forms of modeling used includingRANS, LES, DNS, etc. where the modeling has its own advantages and disadvantages. Among these models,RANS is a model that has the cheapest computer expense compared to other models so that it has the highestworkability. Therefore, rans method testing (Reynolds Averaged Navier Stokes) was conducted to determinethe capability of turbulence models in checking wind speed contours on the road between 4 simplesymmetrical tall buildings with 0o, 30o, and 45o attack an gles validated with the results ofexperimentation. This research was conducted using RANS modeling (Reynolds Averaged Navier Stokes) andstandard turbulence model k-ε and validated using Low Speed Wind Tunnel and PIV (Particle ImageVelocimetry). According to the results of the test, U/Uo wind speed conditions obtained in wind modelingwith RANS and k-ε standards have errors that are still acceptable.

Published: March 2023

Primary melanoma of the duodenum is an extremely rare, aggressive and life-threatening malignant neoplasm. Published data regarding the effectiveness of current treatment strategies is limited, and our knowledge relies mostly on sporadic case reports. The diagnosis of primary duodenal melanoma is challenging and is based on the patient’s medical history and findings from physical examination and radiological and endoscopic imaging as well as proper and careful pathological examinations of the tumor. Despite the many advances in cancer treatment, the prognosis for patients with this type of melanoma remains extremely poor. Delayed diagnosis at advanced disease stage, the general aggressive behavior of this neoplasm, the technical difficulty in achieving complete surgical resection, along with the rich vascular and lymphatic drainage of the intestinal mucosa, all have a negative impact on patients’ outcome. In the present review, we aimed to collect and summarize the currently available data in the literature regarding the pathogenesis, clinical features, diagnosis, management and long-term outcomes of this rare, malignant tumor, in order to expand knowledge of its biological behavior and investigate optimal therapeutic options for these patients. Additionally, we present our experience of a case involving a 73-year-old female with primary duodenal melanoma, who was successfully treated with complete surgical resection.

Published: March 2023

Previous studies suggest that there may be an association between cancer and autoimmune diseases. We describe the case of a 59-year-old patient who did not have any significant diseases in the last year. She had new onset of fever of unknown aetiology, headache, fatigue and night sweats. We used laboratory methods to rule out infectious diseases. Significant laboratory findings reported increased signs of inflammation and anti-nuclear antibody (ANA) positivity. Positron emission tomography/computed tomography (PET/CT) imaging showed the origin of the patient’s difficulties, arteritis, with increased metabolic activity in the aortic wall and other arteries. Doppler ultrasonography of the arteries did not show pathology in the temporal arteries but found accelerated blood flow in the superior mesenteric artery (AMS). Another finding from PET/CT was a tumour in the thyroid gland, later verified histologically as papillary thyroid carcinoma (PTC). We investigated the link between rheumatological disease and papillary carcinoma, applying similar therapy, corticosteroids and immunosuppressants.
Entrepreneurship in Sport: Sport in Business, Using Professional Football as an Example
Authors: Kowalski Wojciech Szymon
Published: March 2023

The issue of entrepreneurship in sports joins the more general trend of catching up with the long Renaissance period of “reflecting” on the character of the professional sportsman (athlete), so peculiarly overlooked, and one of the main protagonists of the culture of antiquity, alongside the artist or philosopher. The author of the article adopts the convention of the ‘corporate athlete’, for which he sees a contemporary exemplification in football, the most popular sport. The examples cited from the economic history of football, preceded by an outline of the basic categories of entrepreneurship, are an attempt to show the essence of an economic, two-way view of these issues. The description of the institutionalisation of analytics and football’s ‘information bank’, highlights the effectiveness of an interdisciplinary approach to entrepreneurship in sport. In contrast, the characterisation of the re-engineering carried out at FC Barcelona is a case of an approach that treats sport as a natural economic environment. Providing a wholesome, inspirational building block, grounding some elements of management and entrepreneurial.
Lower Silesian Factory of Nicotine Preparations
Authors: Synowiec Andrzej
Published: March 2023

The state-owned enterprise under the name of Lower Silesian Factory of Nicotine Preparations (Dolnośląska Wytwórnia Preparatów Nikotynowych; DWPN) with its registered office first in Szalejów Dolny and then in Góra Śląska existed in the years 1952–1958. It produced, above all, nicotine sulphate used by farmers for plant protection (primarily to combat extremely widespread aphids). The plant was managed by the Polish tobacco industry, which supplied the raw material in the form of tobacco waste and waste from tobacco plants. The article first presents the post-war demand of Polish agriculture for nicotine preparations and the plans of the tobacco industry to concentrate their production in one place. Initially, nicotine preparations were manufactured in plants in Szalejów Dolny, Góra Śląska and Kraków-Czyżyny. Finally, under the auspices of the tobacco industry, the DWPN company was established, which produced nicotine preparations for the entire Polish agriculture. DWPN produced approximately 40 tons of nicotine sulphate annually. The plant employed an average of 60–70 employees. Economic reasons and a reduction in the demand for nicotine sulphate resulting from the appearance of cheaper and equally effective insecticides on the market made it necessary to liquidate the plant. The company’s facilities were taken over by the Provincial Union of Enterprises of State Industry in Wrocław.

Im Zuge des Protests gegen die Gentrifizierung St. Paulis, und insbesondere aus dem Kampf gegen den Abriss der sog. Esso-Häuser an der Reeperbahn heraus, entstand die PlanBude – ein interdisziplinäres Team, das als GbR für den Beteiligungsprozess zur Neuplanung der Esso-Häuser vom Bezirk Mitte der Freien und Hansestadt Hamburg beauftragt wurde. Die PlanBude steht auch für den aus zwei Containern bestehenden Raum am Ort der Auseinandersetzung. In einem von zugespitzten Konflikten, Verhandlungen und Vereinbarungen geprägten Prozess entstand eine Neuplanung, die nicht zuletzt durch die Arbeit der PlanBude auf dem „Wissen der Vielen“ basiert. Im forschenden Rückblick lassen sich bestimmte Handlungslogiken hoheitlicher Planung und künstlerischer urbaner Praxis finden, die als grundlegend für den Verlauf des Prozesses und die erreichten Ergebnisse gelten können. Zudem wird herausgearbeitet, wie diese in einem relationalen Raumverständnis wirken und wie im Zusammenspiel die Inhalte normativer Planung verändert werden können.

Infectious Disease as a Security Threat: A Mental Framework for Future Emergency Preparedness
Authors: Houser Ryan Scott
Published: March 2023

The emergence of COVID-19 pandemic has had significant impacts on human lives as well as economic and social stability. The United States has a complicated history with biosecurity. The September 11th terror attacks uncovered various weaknesses in the national biosecurity infrastructure that have persisted into the current pandemic. This study explores the implications of framing the infectious disease biothreat as a security threat to improve our capabilities while protecting against the potential accelerated threat of bioterrorism in the post-COVID-19 era. To counter the increasing biothreats, the United States must invest in revamping the biodefense infrastructure to increase our resilience to various biothreats.

Authors: Tanveer Anum , Abidin Zain Ul
Published: March 2023

The present study describes the peristaltic flow of Jeffrey fluid with nanomaterial bounded under peristaltic waves in a curved channel. Silver (Ag) is the nanomaterial used for this purpose, and base fluid is water. The diversity of peristaltic waves is captured under four different wave profiles traveling along the curved channel. The consequences of heat generation and mass concentration are also taken. The problem is modeled under physical laws and then simplified using the lubrication technique. The obtained system is sketched in graphs directly using a numerical scheme. The physical outcomes of involved parameters on axial velocity, temperature variation, concentration profile, and streamline patterns are discussed in the last section.

Context

Intimate partner violence (IPV) occurs when an intimate partner inflicts physical, sexual, and/or emotional assault with coercive control and is a traumatic experience with repercussions that can be exacerbated when a woman is pregnant. While screening for IPV during pregnancy is recommended to occur regardless of risk, less than 50% of pregnant women are screened.

Objectives

Identifying clinical factors commonly associated with IPV during pregnancy may improve screening rates, thus our primary objective was to examine associations between IPV and maternal comorbidities.

Methods

We conducted a cross-sectional analysis of the Pregnancy Risk Assessment Monitoring System (PRAMS) Phase 8 spanning 2016 through 2019. Bivariate and multivariable logistic regression was utilized to calculate adjusted odds ratios (AORs) to determine associations between IPV and diabetes, anxiety, hypertension, depression, asthma, polycystic ovary syndrome (PCOS), and thyroid disease.

Results

More than 40% of women experiencing IPV reported a history of depression or anxiety. The occurrence of IPV was higher among women with depression (AOR 3.48, CI 3.14–3.85), anxiety (AOR 2.98, CI 2.64–3.37), hypertension (AOR 1.21, CI 1.02–1.44), and asthma (AOR 1.37; CI 1.17–1.59) than women without those respective conditions, but not among diagnoses of diabetes, PCOS, or thyroid disorders.

Conclusions

Our findings show that pregnant individuals reporting having experienced IPV were more likely to report having certain comorbidities compared to those who did not report experiencing IPV. Given the low rates of screening, knowing clinically relevant associations may increase screening sensitivity among clinicians and, in turn, increase the likelihood that individuals experiencing IPV receive supportive care.

Ausgehend von dem Gemeinschaftsgedanken der Bauschaffenden beim Bauhaus und dem Gemeinschaftsansatz von Wohnungsbaugenossenschaften beim Bauen und Wohnen geht diese Abhandlung den Beziehungen und Wechselwirkungen zwischen Beiden nach. Dabei werden die genossenschaftlichen Aktivitäten und Erfahrungen des zweiten Bauhausdirektors Hannes Meyer bei der Planung und Errichtung des Freidorfes Muttenz dargelegt und bis zu einem Manifest des Bauhauses verfolgt. Mit diesem Rüstzeug werden dann die wechselseitigen Auswirkungen von Bauhaus und Genossenschaftswesen beispielhaft erläutert. Dies erfolgt einerseits anhand der Handwerkergenossenschaftlichen Gildenhall, die von ehemaligen Bauhäuslern mitgetragen wurde und andererseits anhand der Wohnungsbaugenossenschaft Trachau-Nord eG, deren Wohnungsbestand aus den zwanziger und dreißiger Jahren des 20. Jahrhunderts, der architektonischen Haltung des Bauhauses folgend, errichtet wurde.
Fortschritt als Denkfigur der Aufklärung in Schleiermachers kirchenhistorischen Arbeiten und ihrer Rezeptionsgeschichte
Authors: Stallmann Marco
Published: March 2023

Schleiermacher’s work on church history was neglected in research for a long time. In a critical examination of the common assessment of Schleiermacher as a comparatively conservative church historian, the study shows to what extent he adopts an Enlightenment category of thought with the concept of progress. In addition, the importance of this appropriation in the historicalphilosophical debate of the 20th century as well as in the more recent debate on church history is asked. It shows that although Schleiermacher’s concept of progress in church history can hardly claim direct normative validity today, there is a remarkable tradition of critical reflection on its opportunities and limitations, the processing of which can serve the constructive self-historicization of contemporary theology.

Wildfire smoke can be transported far from its origin, adversely impacting human health. The height of the atmospheric mixing layer, the near-surface layer of the troposphere in which turbulent convection leads to vertical mixing, is called the mixing height. Mixing height is a critical input in the smoke dispersion and air quality models used by agencies that monitor wildfires and air pollution. These models, coupled with forecaster expertise, are also used to determine if it is safe to execute a prescribed burn. In this paper, we derive mixing heights from two satellite datasets in order to assess mixing height forecasts produced by the National Weather Service (NWS) Fire Weather Program. Namely, we use Cloud-Aerosol Lidar with Orthogonal Polarization (CALIOP) Vertical Feature Masks (VFM) and vertical water vapor profiles from the Moderate Resolution Imaging Spectroradiometer (MODIS). Our comparison indicates that NWS forecasts tend to underestimate CALIOP mixing heights with a median relative error of –13% and a mean relative error of –3.34%. Although MODIS and NWS mixing heights showed some agreement below 3 km, the lower vertical resolution of the MODIS estimates hindered a full comparison. We examine the discrepancies among mixing heights over wildfire smoke plumes determined by these methods and discuss biases and limitations. This work provides insight into potential bias patterns present in current mixing height forecasts and provides directions for future improvements in both NWS mixing height forecasts and satellite-based measurements of mixing height.

Metabolism is controlled to ensure organismal development and homeostasis. Several mechanisms regulate metabolism, including allosteric control and transcriptional regulation of metabolic enzymes and transporters. So far, metabolism regulation has mostly been described for individual genes and pathways, and the extent of transcriptional regulation of the entire metabolic network remains largely unknown. Here, we find that three‐quarters of all metabolic genes are transcriptionally regulated in the nematode Caenorhabditis elegans. We find that many annotated metabolic pathways are coexpressed, and we use gene expression data and the iCEL1314 metabolic network model to define coregulated subpathways in an unbiased manner. Using a large gene expression compendium, we determine the conditions where subpathways exhibit strong coexpression. Finally, we develop “WormClust,” a web application that enables a gene‐by‐gene query of genes to view their association with metabolic (sub)‐pathways. Overall, this study sheds light on the ubiquity of transcriptional regulation of metabolism and provides a blueprint for similar studies in other organisms, including humans.
CEBPB/POU2F2 modulates endothelin 1 expression in prehypertensive SHR vascular smooth muscle cells

Published: March 2023

The pathogenesis of hypertension is not fully understood; endothelin 1 (EDN1) is involved in developing essential hypertension. EDN1 can promote vascular smooth muscle cell (VSMC) proliferation or hypertrophy through autocrine and paracrine effects. Proliferating smooth muscle cells in the aorta are 'dedifferentiated' cells that cause increased arterial stiffness and remodeling. Male SHRs had higher aortic stiffness than normal control male WKY rats. Male SHR VSMCs expressed high levels of the EDN1 gene, but endothelial cells did not. Therefore, it is necessary to understand the molecular mechanism of enhanced EDN1 expression in SHR VSMCs. We identified POU2F2 and CEBPB as the main molecules that enhance EDN1 expression in male SHR VSMCs. A promoter activity analysis confirmed that the enhancer region of the Edn1 promoter in male SHR VSMCs was from −1309 to −1279 bp. POU2F2 and CEBPB exhibited an additive role in the enhancer region of the EdnET1 promoter. POU2F2 or CEBPB overexpression sufficiently increased EDN1 expression, and co-transfection with the CEBPB and POU2F2 expression plasmids had additive effects on the activity of the Edn1 promoter and EDN1 secretion level of male WKY VSMCs. In addition, the knockdown of POU2F2 also revealed that POU2F2 is necessary to enhance EDN1 expression in SHR VSMCs. The enhancer region of the Edn1 promoter is highly conserved in rats, mice, and humans. POU2F2 and CEBPB mRNA levels were significantly increased in remodeled human VMSCs. In conclusion, the novel regulation of POU2F2 and CEBPB in VSMCs will help us understand the pathogenesis of hypertension and support the development of future treatments for hypertension.
