The aim of this research was to analyze the impact of implemented erosion control works (ECW) on soil erosion intensity in the watershed of the Ćelije reservoir (Rasina River) in the period between 1968 and 2022. The Erosion Potential Method was used to calculate the annual gross erosion (W), sediment transport (G), and erosion coefficient (Z) in the study area. As a result of the performed ECW there was a general decreasing trend in the intensity of soil erosion processes in the last 54 years. The specific annual gross erosion was 1189.12 m3/km-2/year-1 in 1968, while in 2022 it was 554.20 m3/km-2/year-1. The specific sediment transport was 540.18 m3/km-2/year-1 in 1968 and 253.55 m3/km-2/year-1 in 2022. Due to the changes in the intensity of erosion processes the specific annual gross erosion decreased by 634.92 m3/km-2/year-1, and the specific sediment transport by 286.63 m3/km-2/year-1. The erosion coefficient was reduced from Z=0.62 to Z= 0.35. A dependence between the slope of siltation and the natural bed slope was defined. The results show a significant correlation between erosion intensity and performed ECW, providing a basis for future watershed management and defining a strategy for soil erosion control in the Ćelije reservoir watershed.

Published: February 2024

Currently, hepatitis B virus (HBV) core antibody (anti-HBc antibody) and HBV core-related antigen (HBcrAg) are widely used as serum markers for diagnosis based on the HBV core region. While anti-HBc is very significant for clinical diagnosis, the clinical significance of quantitative assay of anti-HBc antibody has been reevaluated with improvements in diagnostic performance, including its association with clinical stage and prediction of carcinogenesis and reactivation. In addition, concerning the new HBcrAg, a high-sensitivity assay method has recently been established, and its diagnostic significance, including the prediction of reactivation, is being reevaluated. On the other hand, the quantitative level of anti-HBc antibody expressed in different units among assay systems, complicating the interpretation of the results. However, it is difficult to standardize assay systems as they vary in advantages, and caution is needed in interpreting the assay results. In this review, the clinical usefulness and remaining problems of anti-HBc antibody and HBcrAg were summarized.

Patient access to new oncology drugs in Canada is only possible after navigating multiple sequential systemic checkpoints for national regulatory approval, health technology assessment (HTA) and collective government price negotiation. These steps delay access and prevent health care providers from being able to prescribe optimal therapy. Eighteen Canadian oncology clinicians from the medicine, nursing and pharmacy professions met to develop consensus recommendations for defining reasonable government performance standards around process and timeliness to improve Canadian cancer patients’ access to best care. A modified Delphi methodology was used to confirm strong consensus on 30 questions involving five themes: accountability, disparities, endpoints, timeliness, and cost-effectiveness. It was agreed that greater transparency is required across regulatory and HTA processes. Health professionals in oncology are frustrated for their patients because they are unable to deliver the modern guideline-supported therapies they want to provide due to delays in approval or funding. Canadian patients and their health care providers request improvements in timely access to life-saving therapeutics in line with other countries. Clinicians expect urgent improvements in our health systems to give our patients their best chance of survival.
Green Ammonia Production in Stochastic Power Markets
Authors: Lauro Ezio , Têtu Amélie , Geman Helyette
Published: February 2024

Real assets in the energy market are subject to ecological uncertainty due to the penetration of renewables. We illustrate this point by analysing electrolysers, a class of assets which recently became the subject of a large interest, as they lead to the production of the desirable green hydrogen and green ammonia. The latter has the advantage of being easily stored and has huge potential in decarbonising both the fertilizer and shipping industries. We consider the optimization of green ammonia production with different types of electricity procurement in the context of stochastic power and ammonia markets, a necessary assumption to translate the features of renewable, hence intermittent, electricity. We emphasise the importance of using stochastic prices to effectively model the volatile nature of the price dynamics, illustrating the project risks that can be mitigated by hedging activities. This study shows the pivotal role of flexibility when dealing with fluctuating renewable production and volatile electricity prices to maximise profits and better manage risks.
Quantum Hydrodynamics: Theoretical Framework and Symmetries
Authors: Stephenson Matthew James
Published: February 2024

We present detailed models at the hydrodynamics and decoherence phenomena observed in ideal quantum gases. The model is expressed in terms of a quantum field theory, where the action involves both hydrodynamic and decoherence terms. The density-current relation is derived, and the current Green function is introduced. The effective action for two fields is presented, and the physical field is defined in terms of the bare action. Identities such as CTP symmetry, transposition, and the Ward identity are discussed. The Green function and its inverse for different components are also explored. These notes provide a comprehensive understanding of the theoretical framework for studying the hydrodynamics and decoherence of ideal quantum gases.

Published: February 2024

Flooding is one major environmental problem facing urban cities causing varying degree of damages to properties and disruptions to socio-economic activities. Nigeria is the most populated African country and Kano metropolis is the second largest urban center in Nigeria and the most populated in Northern Nigeria. The aim of the paper is to conduct flood risk assessment of Kano metropolis. The city is divided into two hydrological basins; Challawa and Jakara Basins. Flood frequency analysis for 2 to 100-year return periods were carried out for both the basins using Log-Pearson Type III distribution and flood inundation and hazard mappings were carried out. Social vulnerability to flood of both basins were carried out using MOVE framework. Assessment of flood risk were carried out using map algebra spatial analyst tool in ArcGIS 10.7. The result shows that an area of 50.91 and 40.56 km2 were vulnerable to a 100-year flood. The flood risk map for the two basins show that 10.50 km2 and 14.23 km2 of land in Challawa and Jakara basins respectively are affected by the risk of a 100-year flood out of which 11.48 km2 are built-up area. As the city is densely populated, with a population density of well over 20,000 persons per square kilometer in the highly built-up locations, this means that much more than 230,000 persons will be affected by the flood risk in the two basins

Published: February 2024

Symptoms of poor mental health among working people, especially health workers, are on the rise in the United States, contributing to a burgeoning market of thousands of mental health technology products, few of which have undergone rigorous evaluation. Most research on these products focuses on deploying digital mental health interventions as ancillary support in clinical practice and community settings. Little is known of the effectiveness of these tools when employers offer them.

We describe the landscape of digital mental health interventions, providing an overview of mental health conditions that are addressed with technology-based solutions in the workplace and the products and services available. We argue for employers to apply a methodical approach to evaluating and selecting technologies for their organizations, and we review relevant frameworks for evaluation.

Considering the rapidly evolving landscape of digital mental health interventions, we offer evidence-informed recommendations to organizations and decision-makers seeking to support workplace mental health and well-being, and we advocate the development of products that help organizations assess how they can mitigate workplace conditions that may contribute to poorer mental health.

In recent years Pangasiidae fishes are gaining increased attention, as there is good consumerdemand. Pangasius pangasius was the only known species in south Asia, until the recentdiscovery of Pangasius silasi from India. The bassa fillets of Pangasius boucarti are globallytraded due to its white meat. Having similar characteristic of white meat, P. silasi also appearsto be a promising species. Analysing nutritional composition of P. silasi is important forstrategy formulation aimed at sustainable utilisation of the species. Hence, a comprehensivenutritional profile assessment of P. silasi was undertaken and the results were comparedwith those of other two Pangasids, which are widely traded. Study also evaluated thepotential of this species for mechanised filleting and yield, which is an important parameterin acceptability of fish meat as a marketable product. The results revealed that, P. silasihave fairly high content of protein, n-3 and n-6 fatty acids especially eicosapentaenoic acid(EPA) and docosahexaenoic acid (DHA) and high n-3 to n-6 fatty acid ratio. The high levels ofessential amino acids will position it as superior food source particularly in complementingcereals. Considering its high protein content and healthy PUFA profile, P. silasi emerges as acandidate species for inclusion in human diet at affordable price.

Targeted surveillance was conducted in 37 Penaeus vannamei farms in Tamil Nadu, Indiato find out the prevalence of Vibrio parahaemolyticus (Vp) infections. Special emphasis wasgiven to screen the isolates for acute hepatopancreatic necrosis disease (AHPND). Bacteriawere isolated from haemolymph, stomach and hepatopancreas. Initial identificationswere carried out using the morphological, physiological and biochemical characteristics.Vp isolates were further confirmed by a newly developed multiplex PCR targeting Vp specifictoxR and tlh genes. PCR screening was carried out for AHPND causing AP1, AP2, AP3(pirAvp, Photorhabdus insect-related binary toxin gene) and AP4 (pirAvp and pirBvp) genes.In addition, PCR was also performed for human pathogenic tdh and trh genes. The PCRresults revealed that there were 26 (35.14%) isolates affirmative for Vp specific toxR and tlhgenes and negative for AP1, AP2, AP3 and AP4 genes indicating that there was no AHPNDcausing Vp strain among the isolates. The isolates were also negative for anthropozoonotictdh and trh genes. The multiplex PCR developed targeting Vp specific toxR and tlh geneswould be a useful technique for easy identification of Vp strains from shrimp farms.

Authors: Neelima V. S. , Kaur Simranpreet , Singh Randhir , Gill J. P. S.
Published: February 2024

A loop mediated isothermal amplification (LAMP) assay was optimised for rapid detectionof Listeria monocytogenes from fish by targeting haemolysin gene and compared withconventional PCR and real time PCR (qPCR). All the assays were carried out using differentDNA extraction methods like commercial kit, phenol-chloroform-isoamyl alcohol methodand heat shock method. The analytical sensitivity of LAMP and qPCR was comparable andthe detection limit was found to be 9.6×101 CFU ml-1 from broth and 8×10² CFU ml-1 fromspiked fish whereas the detection limit of conventional PCR was found to be 9.8×102 CFU ml-1and 8×10⁴ CFU ml-1 from broth and fish respectively, when commercial kit was used forDNA extraction. The specificity of all these methods was 100% when compared with relatedbacterial species. The optimised LAMP assay when applied directly on 204 field fish samplesgave an accuracy of 70.59% when compared to the gold standard while conventional PCRshowed a lower accuracy of 52.94%. However, enrichment of LAMP negative samples for 6 henhanced the sensitivity of detection to 100%. The optimised assay detected all negativefish samples by culture as negative hence giving detection specificity of 100%. Moreover,LAMP assay took the least detection time as compared to conventional PCR and qPCR.Thus, the optimised LAMP assay developed can be used as a sensitive, rapid and simpledetection tool for the reliable detection of L. monocytogenes from fish.

Published: February 2024

Rural development is a process of implementing location-specific sustainable modelsutilising ecosystem services with participation of local people. Ezhikkara is a coastalvillage surrounded by brackishwater creeks and Pokkali paddy-shrimp fields located inParavur Taluk of Ernakulam District, Kerala, south India. To address the employment issuesamong rural youth, Ernakulam Krishi Vigyan Kendra (KVK) of ICAR-Central Marine FisheriesResearch Institute (ICAR-CMFRI), initiated cage fish culture in the Veerampuzha public waterbody in association with Pallikkal Service Cooperative Bank (PSCB). Local youth were trainedin the technical aspects of cage fish culture and the bank provided financial support forimplementing cage fish farming. The fish produced were marketed directly to the customersthrough farmgate markets. Farmers sold live fish directly at the farm gate by attractingconsumers through advertisements floated by the KVK. They were sufficiently educated tofix uniform pricing to avoid farmer-farmer competition in direct marketing. An online fishdelivery mechanism by pre-bookings through a mobile application was also established.The cage fish culture got wide acceptance among the rural youth as an alternate incomesource. The main challenges faced during the implementation of cage fish culture wasthe presence of invasive black mussel (Mytella strigata), annual flooding and the massiveaccumulation of weed plant Eichhornia crassipes. This experience unravels the requirementof continuous technical backstopping for marginalised communities to successfullyimplement technology-based farming models as alternate livelihood sources.

Isolation and characterisation of potential bacterialpathogens from Oreochromis niloticus (Linnaeus, 1758) of Lake Hawassa, Ethiopia
Authors: Eregena Alazar , Natarajan P. , Bedewi Zufan
Published: February 2024

The aim of the current study was to isolate and identify potential bacterial pathogens from Nile tilapia, Oreochromis niloticus (Linnaeus, 1758) in Lake Hawassa, Ethiopia. The study was conducted during January to December 2021. A total of 360 Nile tilapia were sampledfrom Lake Hawassa and subjected to bacteriological investigations. The results showed 64.2% prevalence of bacterial infection in Nile tilapia from the lake. Potential bacterial pathogens such as Aeromonas hydrophila, Escherichia coli, Edwardsiella tarda, Vibrio sp,,Bacillus sp., Staphylococcus sp., Salmonella sp., Flavobacterum sp., Pseudomonas sp. and Shigella sp. were isolated. The prevalence of infection in female fish (52.4%) was higher compared to male fish (47.6%). Comparatively higher prevalence was recorded in thesmaller fish group than in the larger ones. The average bacterial loads recorded in various organs such as intestine, skin, gill, liver and kidney were, 4.86±0.56 x 105, 4.72±0.48 x 105, 4.14±0.53 x 105, 3.45±0.23 x 105 and 2.63±0.324 x 105 CFU ml-1 respectively. Significantly high bacterial loads were recorded from the intestine (5.81±0.01 x 105 CFU ml-1) of fishduring the summer season (p<0.05). The results of the study indicated that there is a risk of occurrence of disease outbreak under stressful situations. Moreover, the recovery of these bacteria in the fish which are potentially pathogenic to humans, suggests that if the fish are improperly handled, undercooked or consumed raw, may cause diseases to susceptible individuals.

Published: February 2024

Fishing is an age-old practice and the fisheries sector is vital to India’s economy, whichcontributes to the primary livelihoods of about 2.8 crores of fishers and many more along thefisheries value chain. Fish and fish products constitute about 17% of India’s total agriculturalexports. The sector has been reckoned as a promising contributor to foreign exchangeearnings. The compound annual growth rates of exports and their instability from 2001 to2021 have been worked out for crustaceans, molluscs and frozen fish. The study revealedthat the quantity of crustacean exports has grown at a comparatively high and significantrate of 11.08% during the decade spanning 2011-2021 (Period-II) than during 2001-2010(Period-I). The growth in unit value realised from the export of molluscs declined from5.8% during Period-I to 2.8% during Period-II. The growth in unit value of frozen fish exportdeclined from 10.68% during Period-I to a slow growth rate of 0.11% in Period-II. The declinein the growth of unit values in molluscs and frozen fish indicates a declining demand and, inturn, a declining incentive for future exports from India.

Published: February 2024

Seabass Lates calcarifer is an important brackishwater fish, which thrives and farmed infresh and saline water environment. Differential growth of this species during larval andnursery rearing phases leads to the formation of shooters, which reduces overall survival dueto cannibalism. Therefore, the present experiment was conducted to evaluate the effect ofstocking density on shooter formation, growth and survival of seabass. Hatchery producedseabass seed (total mean length 1.76±0.39 cm; mean weight 0.132±0.10 g) were stocked innet cage hapa (2x1x1 m) installed in brackishwater pond, at four different stocking densities,viz., T1 (800 nos.), T2 (850 nos.), T3 (900 nos.) and T4 (950 nos.) in triplicates. During the45 days of nursery raising, fishes were fed with formulated nursery feed (crude protein: 42%and lipid 8%) at 5 to 8% of body weight three times a day. Initially, the fishes were manuallygraded on 3rd day and later on weekly basis and transferred to separate hapa. Total numberof shooters formed during grading periods (S1, S2, S3, S4 and S5) were counted. It wasobserved that though maximum shooters were obtained from treatment T1 and minimumin treatment T3, the shooter formation among different treatments were not significantlydifferent. The maximum numbers of shooters were obtained during the period from 9 to21 days of rearing in nurseries in all the treatments. A survival of 60% was recorded duringthe present study. Based on the results of this study, it is suggested to maintain stockingdensities of 400-425 m-2 for nursery rearing in hapa. Also, the rearing period from 9 to 21days is significantly critical for ensuring good survival rate.

Published: February 2024

This study provides the first report on the length-weight relationship, reproductive biology and diet of Pomadasys kaakan (Cuvier, 1830) from western Bay of Bengal. Specimens for the study were collected from two locations, Visakhapatnam and Puri, with 301 fishes collected from the former and 153 from the latter. The mean size of P. kaakan at Visakhapatnam was 38.7 cm total length (TL) and 32.07 cm TL at Puri. The length-weight relationship indicated negative allometric growth in the species from both locations. The length at first maturity for female fish was estimated to be 31.5 cm TL at both locations. Our study indicated spawning throughout the year with peaks in February-April and July-August for P. kaakan in the study area. Analysis of diet indicated that in the study region the species had divergent feeding habits. At Visakhapatnam, teleosts (unidentified finfish, eels and silverbellies) were dominant diet items whereas crustaceans (crabs and shrimps) were the dominant diet components of P. kaakan at Puri. The close similarity in size distribution and reproductive biological parameters from the two regions points towards the possibility of a single stock of the species in the study region.

Hydraulic sorting of dredged sediment in a pipeline : an evaluation of the sediment distribution pipe
Authors: Perkey David , Yearwood David , McFall Brian , Harris Brian , Hardy Christopher , Welp Timothy , Eckstein Adrienne , Tyler Zachary
Published: February 2024

The US Army Corps of Engineers (USACE) recently established a goal to beneficially use 70% of material dredged from the nation’s navigable waterways by the year 2030. Most of the sediments dredged by the USACE are heterogeneous mixtures of mud and sand, which can limit beneficial use of dredged material (BUDM) applications. Innovative technologies that can sort material during the dredging process are needed to help increase BUDM practices. This investigation sought to evaluate the ability of a sediment distribution pipe (SDP) to sort particles during transport in a pipeline. Field demonstrations were conducted during dredged material placements at Sturgeon Island, New Jersey. Velocity within the pipeline was found to be inadequate for efficient hydraulic sorting of fines (<75 μm) and produced inconclusive results. Small scale laboratory SDP experiments found that effluent from the SDP holes had an altered sediment texture compared to the initial slurry and that hydraulic sorting was occurring within the pipeline. However, outflow from the SDP holes was inconsistent, and typically >90% of the sediment mass was discharged out the end of the pipeline. Sorting efficiency of the SDP could not be accurately assessed in the current experimental configuration.
Forecasting the Risk of Bankruptcy in Poorly Formalized Processes
Authors: Gaibnazarova Z. T. , Solieva B. T. , Iminova N. A.
Published: February 2024

There is a class of complex systems characterized by dynamism, multi-link structural elements, multi-stage, multi-linked chain of processes. Moreover, each of these processes occurs under conditions of stochastic and non-stochastic uncertainty in the initial information, internal and external environment, which predetermine the uncertainty of the nature of the development of the situation. Decision-making problems in such systems are divided into two types: 1) decision-making problems under risk conditions, when uncertainty conditions are only probabilistic, stochastic in nature; 2) decision-making problems under conditions of uncertainty, when the accompanying conditions are of a non-stochastic nature, and also when the necessary reliable statistical data is unknown. In tasks of the second type, risks are manifested to a greater extent than in the first. At the same time, risk should be considered – as an object, event, phenomenon – as a formal mathematical category in accordance with its following information interpretation: risk is information uncertainty, fuzziness of the “object – subject – environment” system and its individual elements. The measure of this uncertainty determines the measure of danger, possible damage, loss from the implementation of some decision or event. The existence of risk is associated with the inability to predict the future with 100 % accuracy. Based on this, the main property of risk should be singled out: risk occurs only in relation to the future and is inextricably linked with forecasting, and therefore with decision-making in general (the word “risk” literally means “making a decision”, the result of which is unknown). Following the above, it is also worth noting that the categories “risk” and “uncertainty” are closely related and are often used as synonyms. In conditions when the initial factors are given in the form of fuzzy characteristics, other approaches based on the intelligent technologies of Soft Computing are widely used for forecasting. When evaluating alternative decision-making options for risk assessment under uncertainty, the problem of developing fuzzy models based on fuzzy inference rules arises. But there is no universal method for constructing fuzzy evaluation models. The advantage of fuzzy logic lies in the possibility of using expert knowledge about a given object in the form of if “inputs”, then “outputs”. In the paper a bankruptcy risk model is developed in poorly formalized processes for the purpose of forecasting.
New blocked all-pairs shortest paths algorithms operating on blocks of unequal sizes
Authors: Prihozhy A. A. , Karasik O. N.
Published: February 2024

In real-world networks, many problems imply finding the All-Pairs Shortest Paths (APSP) and their distances in a graph. Solving the large-scale APSP problem on modern muti-processor (multi-core) systems is the key for various application domains. The computational cost of solving the problem is high, therefore in many cases approximate solutions are considered as acceptable. The blocked APSP algorithms are a promising approach which can exploit many processors (cores) and their caches in parallel mode efficiently. At the same time, to our best knowledge, all blocked algorithms of the Floyd-Warshall family use blocks of equal sizes. This property limits application of the algorithms. In this paper we propose new blocked algorithms which divide the input graph into unequal subgraphs and divide the matrix of distances between pairs of vertices into blocks of unequal sizes. The algorithms describe the dense subgraphs by the adjacency matrix and describe sparse subgraphs and connections between them by the adjacency list. This approach allows the Floyd-Warshall family algorithms to be used together with Dijkstra family algorithms. It can be applied to large graphs decomposed into dense (clusters) and sparse subgraphs. A new heterogeneous algorithm can significantly reduce the computation time of blocks depending on the block type and size. The contribution of the pa-per is the development of a new family of blocked APSP algorithms which can handle blocks of unequal sizes, save and extend the advantages of the state-of-the-art algorithms operating on blocks of equal sizes. The proposed algorithms are implemented as single- and multiple-threaded parallel applications for multi-core systems.
Empleo de la electroeyaculación en camélidos sudamericanos
Authors:   , Del Aguila Vera Renato Fabián
Published: February 2024

La electroeyaculación es una de las técnicas más utilizadas en camélidos sudamericanos para la colecta de semen. Esta técnica se basa en el uso de voltaje aplicado en la próstata con el fin de estimular los nervios hipogástrico y pudendo, promoviendo así, la erección y, posteriormente, la eyaculación. Es considerada sencilla en cuanto a su aplicación debido a que no requiere de un entrenamiento previo, lo que permite ser aplicada en casi cualquiera animal doméstico y silvestre, sin embargo, debemos tener en cuenta que se necesita utilizar fármacos anestésicos para evitar el estrés de los animales, además de la estimulación a la micción y la limpieza de pene y prepucio para evitar la contaminación de la muestra. En el caso de camélidos sudamericanos se observó que es utilizada principalmente en llamas, sin embargo, también se reporta para alpacas y vicuñas. Los protocolos se basan, principalmente, de Director, et al. (2007), debido a que utiliza voltajes en rangos de 2 a 10 volteos (V), evitando el estrés en los animales y obteniendo muestras con buenos parámetros de concentración, motilidad y volumen. Es por esto que se llega a la conclusión de que la electroeyaculación es una técnica factible para la colecta de semen en camélidos sudamericanos, utilizando voltajes en rangos de 2 a 10V y teniendo un correcto manejo previo a su aplicación, obteniendo muestras viables con parámetros ligeramente menores en comparación a otras técnicas de colecta como la vagina artificial, aspiración post-cópula o colecta de espermatozoides epididimarios.

Los pequeños humedales se encuentran en peligro de desaparecer debido a un mal manejo y al crecimiento urbano acelerado. Esta situación amenaza a las aves que habitan en ellos, especialmente porque algunas son dependientes de estos ecosistemas. El humedal Huacho-Hualmay-Carquín se encuentra en la costa central de Perú. Este ecosistema recién ha empezado a ser estudiado a pesar de que está perdiendo terreno por la urbanización y desarrollo de playas públicas. Realizamos 12 censos de aves (en forma de 2 transectos paralelos: “supralitoral” y “urbano”) entre los años 2019-2021; calculando la diversidad de aves (alfa, beta y gamma) y su correlación con parámetros oceánicos del Pacífico Sur (TSM e ICEN). Encontramos setenta y siete especies con abundancia totales de hasta 19,000 individuos en los meses de verano. La riqueza de especies y abundancia de aves fue mayor en el transecto supralitoral, mientras que la diversidad fue mayor en el transecto urbano. Nuestro estudio encontró correlaciones negativas entre la diversidad alfa con tanto la TSM y el ICEN, y una correlación positiva entre la abundancia total de aves y el ICEN. Este ecosistema presenta una alta diversidad de aves y demuestra la importancia del estudio de pequeños humedales; esto, ayuda a crear mejores planes de manejo y estrategias de conservación en la región.

Ante la problemática de los plásticos sintéticos en el mundo, se han incrementado iniciativas innovadoras que buscan aprovechar los derivados y desechos agrícolas para crear productos biodegradables. El presente trabajo de investigación tuvo como objetivo elaborar platos biodegradables (bioplatos) a base de almidón de yuca reforzado con partículas de cáscara de cacao a través del método de termo-compresión. Las partículas de cacao fueron adicionados a la matriz-almidón en proporciones de 5% (T1), 10% (T2) y 15% (T3). Los resultados obtenidos muestran que la incorporación de fibras lignocelulósicas correspondientes a la cáscara de cacao puede lograr mejoras en las propiedades mecánicas de tracción y módulo de elasticidad, donde los valores de tracción varían entre 0.89MPa y 1.95 MPa, mientras que los valores de módulo de elasticidad varían de 9.59 MPa y 51.88 MPa; siendo el valor más alto para el bioplato con 10% de cacao (T2). Finalmente, en el sistema respirométrico se comprobó la biodegradación del producto elaborado, logrando 18.43% de degradación en sólo 42 días.

Objetivo: Determinar la asociación entre la percepción del estado de salud y el consumo de fibra en personal de salud perteneciente a los servicios de cirugía general y traumatología del Hospital Nacional Daniel Alcides Carrión durante la pandemia por COVID-19 en el 2022. Métodos: El diseño del estudio fue observacional y corte transversal. Se consideraron a aquellos médicos, licenciados y técnicos en enfermería entre los 18 a 59 años de edad, y que no reportaran padecer comorbilidades. La muestra estuvo conformada por 163 participantes. Se envió una encuesta virtual, la cual contenía cuestionario de salud (SF-12), encuesta de frecuencia de consumo (EFCC), cuestionario internacional de actividad física (IPAQ) y puntaje de diversidad dietética en el hogar (HDDS). En cuanto a la frecuencia de consumo de alimentos ricos en fibra, se elaboró un listado de alimentos que contenían entre 3 y 6 gramos de fibra. Resultados: El 59,62% de mujeres presentó buena percepción de salud mental y el 33,90% de varones registró mala percepción de salud física. Se encontró asociación entre la percepción de salud física y el nivel de actividad física (p<0,05). El 88,34% del total del personal de salud reportó ingerir avena, siendo el cereal rico en fibra más consumido a diario, especialmente por los técnicos en enfermería (43,75%). Conclusiones: Se encontró solamente asociación entre la ingesta de avena y la percepción del estado de salud mental, mientras que el consumo de frejol canario se asoció solamente a la percepción del estado de salud física en el personal de salud del Hospital Daniel Alcides Carrión.

Published: February 2024

Introducción: El cáncer de vesícula biliar es una neoplasia relativamente poco común dentro del sistema biliar, caracterizada por una tasa de mortalidad notablemente alta. Nuestro objetivo fue identificar factores pronósticos para la supervivencia general en pacientes peruanos sometidos a cirugía por cáncer de vesícula biliar. Materiales y métodos: Realizamos una cohorte retrospectiva de pacientes con carcinoma de vesícula biliar sometidos a cirugía en el Instituto Nacional de Enfermedades Neoplásicas entre 2000 y 2020. Utilizamos el método de Kaplan-Meier para analizar la supervivencia general (SG) y se emplearon modelos de regresión de Cox para identificar factores pronósticos. Resultados: Se incluyeron un total de 64 pacientes, con una mediana de edad de 62 años y el 75% de ellos eran mujeres. La mayoría de los pacientes fueron diagnosticados en etapa T3 (37.5%) y el 25% presentaba etapa M1. El 51.6% presentaba tumores de grado moderadamente diferenciado y el 71.9% tenía el subtipo histológico adenocarcinoma. Con un seguimiento mediano de 70 meses, la SG fue del 45% a los 3 años. Los factores pronósticos independientes para la SG fueron la etapa AJCC, el grado histológico poco diferenciado (vs. bien-moderadamente diferenciado; HR=2.65, IC del 95%: 1.06-6.63) y un subtipo histológico diferente al adenocarcinoma (HR=3.10, IC del 95%: 1.21-7.99). Conclusiones: Los factores pronósticos asociados con una peor SG en pacientes peruanos con cáncer de vesícula biliar sometidos a cirugía incluyeron una etapa AJCC más alta, grado histológico poco diferenciado y subtipos histológicos diferentes al adenocarcinoma.

Introducción. La investigación destaca la importancia de comprender los factores de riesgo cardiovasculares que pueden influir en eventos cardiovascular adversos mayores tras la cirugía de bypass aorto coronario. Objetivo. Identificar los factores de riesgo cardiovascular (FRCV) que predispongan a un evento cardiovascular adverso mayor(MACE) en pacientes que se sometieron a cirugía de bypass aorto coronario en el Hospital Centro Médico Naval entre los años 2012 al 2020. Métodos. Se llevó a cabo un estudio descriptivo, retrospectivo con diseño transversal, enfocado en pacientes sometidos a cirugía de bypass aorto coronario. Posteriormente, se aplicó un análisis estadístico, específicamente chi cuadrado con un nivel de significancia de p<0.05. Resultados. Se realizó este estudio con 30 pacientes, donde se evidencia que los pacientes que presentaron eventos cardiacos adversos tuvieron una edad promedio de ≥ 67 años. Además, se aprecia que el factor FEVI mientras sea más baja (≤51%), más se asocia a un MACE con un valor P de 0.007 y en el caso de los valores promedios de la glucosa, mientras más alta, tiene un valor significativo en relación con algún MACE; con un valor P de 0.01. Conclusión. Los MACE siguen siendo relevantes tras un bypass aorto coronario. Es crucial enfocarse en adultos mayores, mujeres, pacientes diabéticos y los de FEVI baja, implementando medidas para una vigilancia constante del paciente.

Published: February 2024

El objetivo de este estudio fue evaluar la prevalencia y distribución de cálculos pulpares en un grupo de adultos peruanos mediante tomografía de haz cónico (CBCT). Materiales y métodos: Se analizaron 67 tomografías de haz cónico seleccionadas aleatoriamente de un centro tomográfico en Lima, Perú. Fueron evaluadas 1263 imágenes de piezas dentarias mediante el tomógrafo Point 3D Combi 500 S. El análisis de las imágenes se realizó con el software Real Scan y todas las piezas dentarias fueron evaluadas en las vistas sagital, axial y coronal. Todas las medidas fueron sometidas a prueba de chi cuadrado. (p < 0.05). Resultados: De un total de 67 pacientes, un 83,58% presentaron calcificaciones y de 1263 piezas dentarias, un 30.8% a través de la CBCT. La prevalencia de calcificaciones fue mayor en el sexo femenino que masculino. Los molares maxilares y mandibulares fueron los grupos de dientes con mayor frecuencia de cálculos pulpares. Se encontró significancia entre los cálculos pulpares y el género, rango de edad, tipo y estado de pieza dentaria. Conclusiones: La primera molar maxilar tuvo mayor prevalencia de calcificaciones pulpares que la mandibular. La presencia de caries aumentó la posibilidad de aparición de estas calcificaciones, específicamente en maxilar. La CBCT podría ser una herramienta sensible para detectar cálculos pulpares. El conocimiento de la distribución de cálculos pulpares puede ayudar a los dentistas en el tratamiento clínico de endodoncia.

Waqf refers to a specific form of philanthropic charitable act that is practiced by allocating a non-perishable tangible asset. It involves designating categories of beneficiaries who are entitled to receive its benefits or income. This research investigates the governing structures of Waqf institutions in India and Singapore, with the objective of comprehending the intricate factors that influence their operational functionality. This research aims to explore the differences and similarities in the governance structures of waqf in both countries, considering its significance in their socio-religious landscapes. The main objectives of this comparative analysis are to examine the governance models of Waqf institutions in India and Singapore, identify regulatory mechanisms, and evaluate their impact on the administration and utilization of Waqf assets. Additionally, the study aims to illuminate the socio-economic implications of the differences in governance and assess the effectiveness of each model in preserving the intended socio-religious goals of Waqf endowments. This paper is grounded on research conducted using available written materials, and it embraces the qualitative research framework to analyze the literature at hand. By assessing and comparing the governance of Waqf institutions in India and Singapore, significant disparities are uncovered. India's approach is characterized by decentralization and the existence of various regulatory bodies, Singapore adopts a more centralized approach. The study sheds light on how different governance structures impact the effectiveness, transparency, and sustainable management of Waqf assets. Financial sustainability, community involvement, and adherence to socio-religious purpose emerge as pivotal factors that differentiate the two models.

After the Covid-19 pandemic, it cannot be denied that online shopping has increased shopping behavior patterns using non-cash money. This is due to restrictions on community activities and cash is considered to be a trigger for the spread of the Covid19 virus. This research looks at the phenomenon of using cash as an impact of the Covid-19 pandemic, whether it triggers an increase in non-cash financial literacy and whether government programs for people's movement to use non-cash money can form a non-cash society as a form of effective use of non-cash money or even trigger consumer behavior with minimal understanding non-cash financial literacy. This research uses a qualitative, phenomenal approach by collecting data through interviews with 50 informants with criteria aged 19-21 years and to triangulate the data, interviews were conducted with 2 employees of Bank BSI Jombang and BRI Pulung Ponorogo who have expertise in the banking sector. Based on the research results, it is stated that cashless users aged 19-21 years, influence consumer behavior but have not yet been balanced with detailed knowledge of digital financial literacy and still the function of non-cash money is mostly on shopping behavior so that digital financial skills in non-cash only limited to debits and credits in the cash flow of bank accounts. There is a difference between women and men in usage, namely that men study the products they will buy using cashless and are not easily influenced by promotions compared to women who easily use cashless without studying the details of the products they will buy so they are easily influenced by promotions. It can be used as a basis for policy making in the economic and banking sectors.
