Published: September 2023

La carne bovina es una fuente importante de proteína animal en los hogares costarricenses, cuya cadena de producción se enfrenta al desafío de utilizar eficientemente los recursos escasos a través de la mejora continua de sus procesos productivos y, a la vez, ofrecer la calidad que el mercado demanda, sin perjudicar su rentabilidad. El objetivo de esta investigación es establecer un modelo matemático que permita minimizar el costo de alimentación para el engorde de ganado a partir de una dieta a base de forrajes, subproductos y otros suplementos, en una finca ubicada en Cañas, Guanacaste, Costa Rica. Se utilizó el método de programación lineal sujeto a restricciones según costo y disponibilidad de diferentes alimentos en la zona. Lo anterior permitió obtener diferentes combinaciones de insumos alimenticios al mínimo costo, que garantizan alcanzar los niveles nutricionales requeridos para lograr la ganancia diaria de peso establecida como meta. Los resultados demostraron que, a través del modelo matemático, es posible calcular raciones que garanticen los requerimientos nutricionales necesarios para diferentes objetivos de ganancia de peso diaria, con impacto financiero en la estructura de costos, ya que se optimiza la utilización de los recursos alimenticios disponibles en la zona, los cuales presentan una dinámica cambiante en el corto plazo por temas estacionales y de mercado. Por lo tanto, esta combinación de ingredientes en la dieta de los bovinos, permite disminuir el costo de producción por kilogramo y el tiempo de los ciclos productivos para alcanzar el peso requerido de los animales para salir al mercado. Debido a la importancia del costo de la alimentación en el ganado de engorde, el control de la suplementación es fundamental, tanto de la cantidad como de la calidad de la nutrición.

Published: September 2023

Gracias a su riqueza natural, Costa Rica es hogar de distintas montañas en las cuales muchos senderistas y montañistas se adentran para practicar deporte. Sin embargo, estas actividades son escenario de distintos accidentes, muchos de los cuales surgen a raíz de una mala hidratación. Dichas eventualidades no siempre se dan por falta de agua, sino por la carencia de educación sobre una buena hidratación.
A partir de estos casos, surgió el objetivo de diseñar un gadget inteligente que pueda brindar ayuda para minimizar accidentes o muertes provocadas por una mala hidratación, y evitar el desarrollo de consecuencias corporales a causa de la deshidratación. Además, brindar una herramienta que permita guiar al usuario en lo que debe realizar en caso de verse en una emergencia donde se quede con poca agua o sin esta durante su recorrido.
Para resolver este problema, se hizo uso de análisis de lo existente, de la ergonomía, la perceptibilidad, la funcionalidad y la tecnología, con el fin de conceptualizar una idea, definir sus funciones y su forma; para luego ser llevada a un prototipo funcional que cumpla con las necesidades identificadas por medio del estudio de distintos casos e interacciones directas con usuarios. Basado en lo concluido mediante los estudios, se desarrolló un gadget inteligente que responde a las necesidades de los senderistas y montañistas.

Seventy Years of Unconventional Oil Production from the Bakken - The Impact of Completion and Stimulation Design
Authors: Pearson C. Mark , Strickland Stacy , McChesney Jeromy , Griffin Larry G. 
Published: September 2023

Abstract
Unconventional oil production started in the Bakken formation of North Dakota in 1953. For the first fifty years, the rate of drilling was slow and measured with the scope of activity driven by delineation development associated with naturally fractured structural features and higher permeability formation facies at the edges of the basin. Production got a boost with the advent of horizontal drilling in 1987. However, it was not until twenty years later with the advent of multi-stage hydraulic fracturing of the horizontal lateral that completion and stimulation design advanced to a level which allowed economic development across the whole basin – regardless of structure or existence of a high permeability "sweet spot" facies.
Through 2022, a total of 18,833 wells have been drilled and completed in the Bakken Petroleum System across the United States portion of the Williston Basin. Comparing geologic data, completions parameters and state-reported production results it is possible to understand the fundamental well completion and stimulation changes that have guided industry to develop economic well results over the past seventy years of development. These well completion and stimulation advances have provided industry the opportunity to move from core geologic "Tier 1" areas of the basin to what is referred to as "Tier 2" and "Tier 3" areas which are characterized by an absence of structurally induced natural fracturing or higher permeability geologic facies. In addition, recent drilling and completions optimization has allowed industry to economically develop lower pore pressure and higher water cuts areas that are geographically located away from the highest pressure, deepest part of the basin.
These completion advances have allowed the region to compete on a global scale with production that peaked at 1.49 Million bopd and has now stabilized at ~1.1 Million bopd.

Published: September 2023

Abstract
Flooding drives considerable risks. Designing strategies to manage these risks is complicated by the often large uncertainty surrounding flood risk projections. Uncertainty surrounding riverine flood risks can stem from choices regarding boundary conditions, model structures, and parameters as well as interactions among hazards, exposures, and vulnerabilities. Flood risk assessment involves multiple research disciplines including the fields of atmospheric science, hydrology, and socioeconomics. A quantitative understanding of which factors contribute most to uncertainties surrounding flood hazards and risks can inform the design of mission-oriented research. Here we analyze a case study to rank the drivers of uncertainties surrounding riverine flood hazards and risks. We find that the projected flood risk is most sensitive to factors associated with flood hazards, rather than exposure and vulnerability: upstream discharge, river bed elevation, channel roughness, and the digital elevation model resolution. Our framework and results can help to improve flood-hazard and risk projections.

Published: September 2023

Abstract
In the manufacture of steel rods, the subsequent accidents may cause colossal time and economic losses if certain abnormality cannot be found and handled in time. Therefore, it is necessary to achieve comprehensive supervision in the production which requires timely and precise recognition of steel abnormalities. The existing recognition method does not perform well in recognizing such abnormalities: Methods that rely on human observation or traditional image processing are computationally expensive and inefficient. In contrast, frame-based object detection methods suffer from the error of recognition due to the inability to extract temporal information. In this paper, we proposes an effective method based on YOWO for video-based steel abnormalities, which enjoys both high efficiency and high performance. Specifically, our method consists of two parts, a novel cliplink module and a temporal data augmentation technique. Contrast the previous approaches, our method can make better use of temporal information to recognize the steel abnormalities. To better validate the effectiveness of our method and address the data deficiency of this task, we also propose a domain-specific dataset for steel abnormalities recognition. In the dataset, we achieves 81.5 mAP in accuracy and 40 FPS in speed, which demonstrates the significant advantages of the improved method.

Abstract
Background
Mucopolysaccharidosis (MPS) type VII is a storage disorder of autosomal recessive origin caused by a deficiency in a lysosomal enzyme that results in accumulation of glycosaminoglycans and in secondary metabolic pathway problems. It has systemic symptomatology that mainly includes progressive skeletal dysplasia, cardiovascular manifestations, hepatosplenomegaly, coarse facies and many other manifestations, with cognitive decline in most cases. A significant proportion of patients may present fetal hydrops. Pathogenic variations frequent in specific ethnic groups explain the higher incidence in some groups due to founder effect and/or endogamy. In Brazil, the variant most commonly found is the p.Leu176Phe. This study aims to investigate GUSB expression of the patient with MPSVII with a new mutation (p.Leu292Pro). Also, it has been investigating the ancestry 5 patients with MPS VII from Brazil regarding the Amerindian, African and European contribution.
Results
Analyses allowed the identification of different proportions in the population contribution in the sample of patients with MPSVII with the highest European contribution which is significantly different (p = 0.0031) from the African contribution. Relative expression analysis by the 2−ΔCT method that showed superior expression of the GUSB gene in the patient with MPSVII compared to the group without the disease. Relative the comparison among threshold cycles, 14/20 samples showed significantly different CT values for the patient with MPS VII when comparing the amplification cycles. The relatives also showed different values (p < 0.05) for the amplification cycles. The in silico prediction of the new variant indicated it as pathogenic by modifying a highly conserved region.
Conclusions
It has been indicated that the Leu176Phe mutation is possibly of European origin. There is a discrepancy between the levels of mRNA for GUSB and the amount of beta-glucuronidase synthesized. The p.Leu292Pro mutation is indicated as pathogenic, but its impact on the MPS VII phenotype still need to be fully elucidated.
How Delphi studies in the health sciences find consensus: A systematic review
Authors: Spranger Julia , Niederberger Marlen 
Published: September 2023

Abstract

Background: Delphi studies are primarily used in the health sciences to find consensus. They inform clinical practice and influences structures, processes and basic conditions in healthcare. The practical research–how Delphi studies are conducted–has seldom been discussed methodologically or documented systematically. The aim of this systematic review is to fill this research gap and derive guidance regarding the quality of Delphi studies.
Methods: Forming the basis of this systematic review are publications on consensus Delphi studies in the health sciences between January 1, 2018, and April 21, 2021, in the databases Scopus, MEDLINE via PubMed, CINAHL and Epistemonikos. Included were publications in German and English containing the words "Delphi" in the title and "health" and "consensus" in the title or abstract. The practical research was analyzed for the qualitative content of the publications according to three deductive main categories, to which an influence on the result of Delphi studies can be imputed (expert panel, survey design, process and feedback design).
Results: A total of 287 consensus Delphi studies were included in the review, whereby 43% reported having carried out a modified Delphi. Most of the time, heterogeneous expert groups from research, clinical practice or health economics and health policy were surveyed. In about a quarter of the Delphi studies, affected parties, such as patients, were part of the expert panel. In the Delphi questionnaires it was most common for standardized Likert scales to be combined with open-ended questions. Which method was used to analyze the open-ended responses was not reported in 62% of the Delphi studies. Consensus is largely (81%) defined as percentage agreement.
Conclusions: The results show considerable differences in how Delphi studies are carried out, making assessments and comparisons between them difficult. Sometimes an approach points to unintended effects, or biases hint at the individual judgments of the respondents and, thus, at the overall results of Delphi studies. For this reason, we extrapolate suggestions for how a certain comparability and quality assurance can be achieved for Delphi studies.

Abstract
Background: Despite efforts to improve neonatal care worldwide, neonatal mortality rates in sub-Saharan Africa,including in Malawi, remain high, with a need for space, equipment, and staff. We evaluated the impact of establishing a district-level neonatal nursery and subsequent strengthening efforts over seven years at Neno District Hospital, Malawi.
Methods: We conducted a retrospective cohort study to measure the neonatal outcomes before nursery establishment (study period I, 2014-2015), following the establishment of a nursery (study period II, 2016-2018), and ongoing strengthening efforts (study period III, 2019-2021). We extracted data from neonatal registers and employed descriptive statistics and chi-square tests to compare the overall neonatal outcomes between admission periods. We then performed logistic regression to isolate factors associated with neonates alive atdischarge from the neonatal nursery.
Results: In a review of nursery capacity, nursery establishment in 2016 included initial inputs of equipment, medications, and systems with increased support of space, human resources, and additional systems with the transition to a larger nursery in 2019. Of the 1366 neonates observed over the entire study period (2014-2021), the three primary admission diagnoses were birth asphyxia (30%, n=411), sepsis (29%, n=396), and prematurity (21%, n=286). The proportion of neonates discharged alive increased from 62% to 74% to 88% in study periods I, II, and III, respectively. The odds of being discharged alive were four times higher in study period III than in study period I (OR=4.34; 95% CI: 2.6-7.04; p<0.001) and increased sixfold after adjusting for sex (aOR=6.51; 95% CI: 3.69-11.5; p<0.001). Neonates admitted with prematurity were less likelyto be discharged alive (OR=0.56; 95% CI: 0.38-0.82; p=0.003) than other diagnoses. The odds of being discharged alive for neonates weighing 1500-2500 g were five times higher than those weighing <= 1500 g at birth (aOR=5.25, 95% CI=2.61-10.7, p<0.001).
Conclusions: Neonatal nursery services and outcomes improved with nursery establishment at Neno District Hospital and improved with increased inputs over seven years. A multidimensionaldecentralized approach at a district hospital with adequate space, staff, equipment, and medications is vital to treating sick neonates and decreasing neonatal mortality.
The prevalence and determinants of unintended pregnancy among pregnant women attending antenatal clinic in the primary health care at KAMC- Jeddah
Authors: Wali Razaz 
Published: September 2023

Abstract

Background Unplanned or unintended pregnancy is one of the major health issues globally and regionally. It poses many health, psychological, and financial impacts on the individual and the health system. Some determinants can affect women's decision to become pregnant; tackling these determinants can give policymakers a better understanding of the current health issue and help them develop recommendations accordingly.
The aim of this study is to identify the prevalence and determinants of unintended pregnancy in pregnant women visiting the antenatal clinic in the primary health care centers in the western region of Saudi Arabia from September 2022 to July 2023.
Methods An analytic cross-sectional study was conducted in Jeddah from September 2022 to July 2023. A nonprobability convenient sampling method was used to recruit 346 pregnant women booked in the Primary Health Care antenatal clinics; the data were collected using the modified Arabic version of the London Measure of Unplanned Pregnancy (LMUP). The data from the questionnaire were analyzed using Statistical Package for Social Science (SPSS) version 22.
Result The prevalence of unplanned pregnancy among the study population was 17.6%. There is a significant association between unplanned pregnancy and the duration between the last two pregnancies, having thoughts and actions to terminate the pregnancy, and meeting the contraceptive needs. Maternal age, level of education, andfamily income were not associated with the rate of unplanned pregnancy.
Conclusion Unplanned pregnancy is prevalent in Western Saudi Arabia but is low compared to other parts of the world. Multiple risk factors can determine the risk of unplanned pregnancy, including women's education, family income, and meeting contraceptive needs. Public health uses these indicators to understand population fertility and women's health services and reduce the rate of unplanned pregnancies, a key objective for Saudi Arabia.
