Bounded Surjective Quadratic Functions over Fnp for MPC-/ZK-/FHE-Friendly Symmetric Primitives
Authors: Grassi Lorenzo
Published: June 2023

Motivated by new applications such as secure Multi-Party Computation (MPC), Fully Homomorphic Encryption (FHE), and Zero-Knowledge proofs (ZK), many MPC-, FHE- and ZK-friendly symmetric-key primitives that minimize the< number of multiplications over Fp for a large prime p have been recently proposed in the literature. These symmetric primitives are usually defined via invertible functions, including (i) Feistel and Lai-Massey schemes and (ii) SPN constructions instantiated with invertible non-linear S-Boxes. However, the “invertibility” property is actually never required in any of the mentioned applications.In this paper, we discuss the possibility to set up MPC-/FHE-/ZK-friendly symmetric primitives instantiated with non-invertible bounded surjective functions. In contrast to one-to-one functions, each output of a l-bounded surjective function admits at most l pre-images. The simplest example is the square map x → x2 over Fp for a prime p ≥ 3, which is (obviously) 2-bounded surjective. When working over Fnp for n ≥ 2, we set up bounded surjective functions by re-considering the recent results proposed by Grassi, Onofri, Pedicini and Sozzi at FSE/ToSC 2022 as starting points. Given a quadratic local map F : Fmp → Fp for m ∈ {1, 2, 3}, they proved that the shift-invariant non-linear function over Fnp defined as SF (x0, x1, . . . , xn−1) = y0∥y1∥ . . . ∥yn−1 where yi := F(xi, xi+1) is never invertible for any n ≥ 2 · m − 1. Here, we prove that • the quadratic function F : Fmp → Fp for m ∈ {1, 2} that minimizes the probability of having a collision for SF over Fnp is of the form F(x0, x1) = x20 + x1 (or equivalent);• the function SF over Fnp defined as before via F(x0, x1) = x20 +x1 (or equivalent) is 2n-bounded surjective.As concrete applications, we propose modified versions of the MPC-friendly schemes MiMC, HadesMiMC, and (partially of) Hydra, and of the FHE-friendly schemes Masta, Pasta, and Rubato. By instantiating them with the bounded surjective quadratic functions proposed in this paper, we are able to improve the security and/or the performances in the target applications/protocols.

Redefinicija nacionalnog konteksta u Crnoj Gori i srpska (veliko)državna ideja
Authors: Mrduljaš Saša
Published: June 2023

Distanciranje Crne Gore od državne zajednice sa Srbijom otpočinje krajem 1990-ih, u vremenu u kojem je promotorima srpske velikodržavne ideologije izrazito sužen prostor da takvo što spriječe silom. Stoga se posegnulo za drugim instrumentima usmjerenima na uništenje ili minoriziranje identitetne konstrukcije nacionalnog crnogorstva među pravoslavnom populacijom Crne Gore te na njezino nadomještanje nacionalnim srpstvom, uz ispravnu procjenu da je nacionalno crnogorstvo glavna snaga u samosvojnom uobličavanju Crne Gore. Takva kojoj je najbolje suprotstaviti od dijela nekadašnjih nacionalnih Crnogoraca oblikovani »srpski narod u Crnoj Gori« kako bi se tu zemlju zadržalo, odnosno, nakon postizanja neovisnosti 2006. vratilo pod srpsko državno okrilje. U ovome radu dat ćemo prikaz povijesnog razvoja koji je omogućio da prikazani vid srpskog velikodržavnog djelovanja u Crnoj Gori bude relativno uspješan, a zatim i uvid u postojeće političke i nacionalne-demografske suodnose u toj zemlji. Ujedno, analizirat ćemo uzroke koji utječu na to da se nacionalno crnogorstvo teško nosi s pokušajima vlastite identitetne destrukcije te istaknuti razloge zbog kojih bi u svojim naporima za samoodržanjem trebali dobiti sasvim konkretnu podršku regionalnih i euroatlantskih struktura.

Researching Elite Interviewing in Higher Education in Postcolonial Bangladesh
Authors: Kabir Ariful Haq
Published: June 2023

The concept of “elite interviewing” is a recent phenomenon in educational research and has been studied widely in the Western context. Drawing on my own experience, this article traces the challenges and difficulties involved in “elite interviewing” in higher education in post-colonial Bangladesh. It is based on a critical methodological perspective, using a thematic analysis of interviews with 28 higher education policy-making elites working between the 1990s and 2010s at the state level in Bangladesh. This article examines how the local power structure within the current socio-political context emerged from a long colonial past, and how this in turn influenced elite interviewing. It looks at how the researcher, who’s onto-epistemological as well as geopolitical position originated from and has been influenced by both Global South and Global North contexts, negotiated with this distinctive power structure in elite interview settings to understand the “micro-politics” of neoliberal policy formulation in Bangladesh. In its critical analysis of elite interviewing, this paper traces how “everyday social practices” drawn from colonial practices, for example, the use of “sir” and acknowledging “supremacy” and “power conflict” served as a form of “capillary” domination of relations to respond to the power structure and neutralise specific identities, positions, and experiences in elite interview settings.

Published: June 2023

Active ageing is a multidimensional, relative, and context-dependent concept with different paths and outcomes. This qualitative study aimed to explore personal active aging strategies in a specific context. Following a directed thematic analysis procedure, we conducted semi-structured individual interviews with 39 seniors (men and women) between the ages of 60-97 years selected with purposeful sampling, data collection and analysis were concurrent. We used directed content analysis to analyze the data from interviews, written narratives, and field notes. The reliability of data was fulfilled following Lincoln and Guba criteria. We stopped data collection when no new concepts were added, and data saturation occurred. Based on the experience of seniors, we identified four categories: (a) Reventive, (b) Coping, (c) Internal Self-Control, and (d) Opportunity Exploiting Strategies. These described the active aging strategies when encountering age-related change. Utilizing these strategies, the senior accompanied the lifetime. The finding suggests that active aging is a continuous process in confronting age-related change. The identified strategies can help promote active aging by familiarizing the elderly with opportunities of life and training them in how to use these strategies.

Authors: Estrada Samantha , Martinez Erica
Published: June 2023

In recent years, the adjunct faculty phenomenon has grown steadily. This research focused on adjunct instructors teaching introductory statistics courses. The purpose of the study was to give a voice to adjunct instructors by allowing them to describe their experiences teaching statistics. We conducted a qualitative study with 15 adjunct instructors of introductory statistics through semi-structured interviews. The participants came from several fields: psychology, nursing, and business, among others. Thematic analysis was used to find themes of statistical anxiety, use of technology in the classroom, lack of curriculum flexibility, and connection to the host institution. Our findings can inform institutions and interdisciplinary departments hosting introductory statistics courses. Similarly, educational statisticians can gain knowledge on the practices and barriers of adjunct instructors.

Citizen Centered Approach to Preventing Violent Extremism: A Case of Somaliland
Authors: Adad Mohamoud Saed
Published: June 2023

The Horn of Africa region has been tackling prolonged ideology-based extremism for over two decades. Several factors are believed to have fueled the rise of extremism in the region, including but not limited to poverty, marginalization, lack of youth engagement, limited integration among regional states, limited access to formal education, and religious misconceptions. Somaliland, which is internationally part of Somalia but declared independence and regulated itself for the last 30 years; has succeeded in controlling both extremism and other forms of violence such as the pirates with a unique approach to citizens' engagement as a community policing. Violent extremism massively penetrated the region with its strong base in Somalia. Despite progress in countering and preventing violent extremism with regional effort and international community support, there is no single strategy and best practices applied by all regional governments to prevent violent extremism. Therefore, this paper will assess the new paradigm of prevention with the Somaliland approach of citizen engagement and how these elements contributed prevention of extremism spread across the border to neighboring countries and beyond. This study will employ a Trust-Based, Qualitative Methodology developed by ICEPCVE. The reason is to assess the impacts of National and Regional Efforts in Countering and Preventing Violent Extremism explicitly and accurately. This paper will unpack Somaliland's approaches to tackling these global and regional challenges of violent extremism and the secret of stability for more than 30 years, what other countries can learn about it, and how with thoughtful recommendations.

Detection of Reactive Oxygen Species during Photodynamic Therapy
Authors: Pal Dipakshi
Published: June 2023

Reactive oxygen species (ROS), also known as oxidants, are often utilized in a variety of therapies, such as in photodynamic therapy (PDT) which is an emergent cancer and tumor therapy. The production of ROS in cancerous cells induces oxidative stress, promoting apoptotic cell death. Here we utilize fluorescent molecular sensors to quantify the generation of ROS by a photosensitizer and a room-temperature plasma source.  We observe a linear increase in the production of ROS in solution, as a function of light irradiation dose, as measured by the intensity of fluorescence of sensor molecules. The same trend was also observed using the plasma source. It was also observed that in both experiments the signal saturated after prolonged irradiation time. This can be attributed to finite concentration of sensor molecules present in the solution. While ROS production can continue to increase linearly due to further irradiation, the increase in ROS can no longer be detected after prolonged irradiation time due to the limited number of sensors in the sample.
The Importance of Family, Peer, and Romantic Relationships on Adolescent Development
Authors: Xu Ruiyuan
Published: June 2023

Family, peer, and romantic relationships each hold significance in adolescents’ developmental success. This paper reviews how each relationship uniquely contributes to the development of the 5 Cs of positive youth development (competence, confidence, connection, character, and caring). Research shows that a high-quality connection between parents and children can help adolescents' confidence and competence increase. As teenagers grow up, peers start to take over more time in teens' life and direct them to different futures. Since peers mold an individual's character, being part of a positive peer group can bring countless benefits and lead teens to success all around. Finally, romantic relationships are especially promising for cultivating care among adolescents. The paper concludes with recommendations for how parents can support their children’s positive development through the formation of healthy and fulfilling relationships.

Authors: C OLISE Moses , Raluchukwu EKEH Angela , Christian OJIAKU Obinna
Published: June 2023

This research work is on the effect of sustainable marketing on student purchase behavior of iPhone 13. Sustainable marketing is the process of the creation, communication and delivery of consumption values to the consumer with a view to meet their needs and observe the requirements of environment preservation without jeopardizing the possibilities of meeting the needs of future generations. Consumer purchase behaviour is the selection and consumption of goods and services for the satisfaction of their wants. It is also the sum total of a consumer’s attitudes, preferences, intentions, and decisions regarding the consumer’s behavior in the marketplace when purchasing a product or service. iPhone 13 is a sustainable phone which many students use. Consumer purchase behavior and the Theory of Planned Behavior explains the relationship between some factors and human behavior, though not exhaustive. The aim of this study is to know the extent sustainable marketing affect student purchase behavior of iPhone 13, and this will be achieved using consumer attitude and green marketing tools (eco labeling, eco advertisement, eco branding) as variables to measure this study. Four hypotheses were formulated in line with the above objective. The population of the study was made up of undergraduate student of Nnamdi Azikiwe University. The sample size was calculated to be 400. A structured questionnaire was used for collecting data for this research work. Both primary and secondary data was used for clarity. Multiple regression was used to test for the effect of the sustainable marketing variables on purchase behavior (student) with the aid of SPSS version 20. The researcher tested for the level of significance and effect of sustainable marketing on students purchase behavior on iPhone. The result showed that there is a statistically significant effect of sustainable marketing on student purchase behavior of iPhone 13. Recommendation was also made.
Feminist Methodology and Contemporary Feminist Research in India
Authors: Mukherjee Dr. Poulami A.
Published: June 2023

Feminist methodology seeks to assess knowledge-generating strategies in terms of their suitability for feminist research. Feminist methodology is not to be identified with any particular object of study or specific set of theories, doctrines or knowledge claims. This type of research is a self-reflexive inquiry that seeks knowledge for emancipation and which challenges asymmetric and inequitable constructions. Historically, feminist research expanded the theories and objects of investigation to a focus on women, then their work moved towards recognizing gender disparities and then even more specifically moved to contemporary critiques that include the investigation of the types of methods used in all research; the analysis of how theories are incorporated into the research; the critique of how evidence is gathered; and determination at higher levels of abstraction in what counts as truth and authority. The present study will try to focus on problematic of feminist research and what should be the basic components of feminist research methodology in contemporary India.
Merging Participatory Action Research and System Dynamics as a Locus for Transformation in a Large Scale Hospital Setting
Authors: Ansermeah MMF
Published: June 2023

In this paper, we report on the utility of merging Participatory Action Research (PAR) with System Dynamics (SD) as a locus for stimulating transformation in a large-scale hospital academic setting.  This is significant because it provides points of cross fertilisation whereby the two frameworks act synergistically with each other to create high leverage interventions for change, which may otherwise not have been apparent. Coupled within a SD auspice, there was a synergistic blend of uncovering an overall ecological view of the public health care system. The PAR methodology is located within the epistemological realm of critical theory and constructivism, whereby facilitating positive social change is viewed to be the key outcome of such research. This outcome has been confirmed by the researchers prioritizing the necessity for a departure from the traditional expert-led health system, evolving into one which supports the empowerment of patients and health-care workers as a necessity. However, the implementation of the improvements has not been as straightforward as initially projected. Some of the challenges included the slow assimilation of proposed solutions for planned care and paucity of key engagement from upstream stakeholders. The value of this paper can potentially serve to encourage key stakeholders in public health care systems to consider viewing health care complexity through the lens of PAR and SD.

Authors: M. A Yousef , K. AL TAAE Ali
Published: June 2023

At the end of April 2020, a field survey was conducted in the barley fields of Nineveh province to detect barley Ear cockle disease caused by infection with nematode Anguina funesta and to estimate the percentages of infection with this disease, the percentage was 8,2,5,1,10% for each of Hamdaniya,Bashiqa, Bartella, Al-Boir and Khirbet Malak,. respectively. The infected samples were collected for several varieties of barley after obtaining the adult stages at the beginning of the formaation of the ears and comparing their morphological characteristics with those close up to them such as Anguina spp. Pathogenicity of the nematodes in barley plants was also confirmed by Koch’s postulates. Molecular identification of Anguina isolates was done by amplifying the internal transcribed spacer (ITS) region of the conserved ribosomal DNA using primers ITS1 and ITS4. All the ITS sequences were compared for gaps and similarity sequences of the nematodes were homologous to those of A. funesta. isolates in the GenBank database with a similarity percentage of 95%, thereby confirming the identity of the causative agent of the disease. To the best of our knowledge this is the first record of A. funesta on the barley in Ninevah Governorate in Iraq. The nucleotide sequence of ITS from the Iraqi isolate has been assigned GenBank Accession No ON721332.1.

EFFECTS OF ENHANCER DIESEL FUEL AND VIBRATING WINGS SUBSOILER PLOW ON THE PERFORMANCE OF AN AGRICULTURAL TRACTOR
Authors: T. TAHA Hussam , Y. HILAL Yousif
Published: June 2023

The aim of the study was to investigate the fuel consumption, depth stability ratio, noise, driver seat vibration of agricultural tractors (DSV), and slippage during tractor operation by using a kind of fuel (enhancer and non-enhancer fuel), vibration and non-vibration wings of subsoiler and engine speeds. Three engine speeds that include 1000, 1500 and 2000 rpm were considered. The results indicated significant positive data for all traits under enhancer fuel compared with non-enhancer and studies treatments. The experiment was analyzed as a three-factor factorial experiment using a split-split plot- Randomized Complete Block Design. Duncan's multiple range test used to test for significance. The results showed positive superiority of enhancer fuel in the fuel consumption, depth stability ratio, noise, DSV, and slippage, while achieving a negative increase in DSV, noise, and slippage with wing vibration of subsoiler. However, the DSV for wing vibration of subsoiler remained within European Parliament and Council Directive 2002/44/EC (OJ, 2002) and the measurements previously approved from ISO 2631-5 (2004). Besides, increasing the engine speeds leads to an increase in noise, DSV, and slippage, while at 2000 rpm speed of the engine was recorded as the lowest value of 11.905 L. ha-1 for fuel consumption, respectively. Finally, the results indicate the superiority of enhancer fuel and vibration wings at all engine tractor speeds to register less fuel consumption, DSV and slipping lead to the conclusion that adding enhancer fuel improved the performance of the agricultural tractor.

Authors: Ajayi Rachael Adejoke , Aranmolate Temitope Raheedat
Published: June 2023

Purpose: The study examined the appropriation of adult education for academic achievement towards sustaining the rights of physical challenged students in higher institutions in Lagos.

Methodology: The research design employed in the study was a descriptive survey. The population consisted of all higher institutions located in Lagos State. To gather data, a simple random sampling technique was utilized to choose ten (10) higher institutions from which fifteen (15) physically challenged students were selected from each institution. This amounted to a sample size of one hundred and fifty (150) respondents for the study. The data collection process utilized a self-developed questionnaire as the primary instrument. It was developed in 2 Likert scale of Agreed and Disagreed. The instrument was moderated by experts who affirmed its validity. The reliability of the instrument was assessed through the utilization of the Pearson Product Moment Correlation Coefficient (PPMC). The data collected were then analyzed using statistical tools such as simple percentage and standard deviation.

Findings: The study's findings indicated that adult literacy significantly contributes to adult sustainable development, fostering economic, social, and environmental sustainability. Furthermore, it establishes conducive circumstances for empowering active global citizens. By effectively employing adult education, individuals with physical challenges can acquire a comprehensive comprehension of various concepts and lead their lives in a proficient manner.

Unique Contributions to Theory, Policy and Practice: Adult education has a wide-ranging positive influence on various aspects relevant to adults. Importantly, these advantages extend beyond the professional sphere and encompass different aspects of daily life for individuals with physical challenges. These benefits extend beyond the professional realm and extend to various facets of everyday life for physically challenged individuals. As a result, it is recommended that to guarantee the sustainability of the human rights of physically challenged students, the government should assume the primary responsibility of providing trained and qualified teachers/facilitators, along with other supportive staff, who will cater to the educational needs of these special students.

Purpose: The successful implementation of VBS entails eight process elements of activity Yet Practical application showed a difference between theory and practice when its about to turning the concept into action in entrepreneurial domain, to address this gap this study aims to contribut to the improvement of the VBS implementation processes by exploring and designing a Product Centric VBS model for entrepreneurs, and by doing this to contribute to the general body of knowledge of VBS.

Methodology: The research design builds on the Descriptive practice-oriented research methodology.

Findings: While our study confirms earlier research on value-based selling antecedes and consequences we also identify epistemological assumption that the marketing organizational tier is the appropriate level for initiating VBS elements of activity hence the value co-creation process will be rationally superseded by value pre-crafting in collaboration between supplier and transitional entrepreneur.

Unique Contributions to Theory, Policy and Practice: As earlier studies for Successful implementation of value-based selling and the conceptualization of the approach adopted a customer value co-creation perspective. These descriptions can form first stone in the milestone for further research in which propositions could be tested based on the assumptions that we used when we elaborated the parameters that form the construct of the model that we developed.

Los métodos serológicos son más sensibles, pero los estudios en pacientes inmunodeprimidos son escasos. El objetivo del estudio fue de evaluar la sensibilidad de una prueba ELISA comercial en pacientes inmunodeprimidos. Métodos: se realizó en Bolivia un estudio multicéntrico en pacientes con cáncer, VIH, enfermedades reumatológicas y hematológicas. 88 pacientes con larvas de S. stercoralis en heces identificadas mediante técnicas coproparasitológicas tuvieron una prueba serológica ELISA (Bordier Affinity Products). Resultados: la sensibilidad de la técnica ELISA fue de 77,3% (61/88) (CI95%: 67,7-85,1). La sensibilidad de este test serológico fue identificada más baja en pacientes HIV+ con CD4<300 (64,5%) que en pacientes HIV+ con CD4>300 o una serología VIH desconocida (84,2%) (p=0,035). Conclusiones: la sensibilidad del ELISA es inversamente proporcional al grado de inmunosupresión. Este resultado refuerza la recomendación de diagnosticar la estrongiloidiasis mediante una combinación de técnicas serológicas y coproparasitológicas.

Introducción: el conocimiento y la percepción hacia los medicamentos genéricos son temas que surgen como un factor importante a explorar en los estudiantes de medicina. Objetivo: determinar las diferencias entre los estudiantes de medicina de universidades públicas y privadas sobre la percepción y el uso de las Especialidades Farmacéuticas Genéricas (EFG). Materiales y métodos: se realizó un estudio cuantitativo de tipo observacional, transversal, analítico y comparativo en un universo de 858 estudiantes matriculados durante 2019-2020 en cinco escuelas de medicina del estado mexicano de Tabasco. A través de Google Forms se recolectaron los datos de un formulario auto aplicado con base a un cuestionario previamente validado. Se emplearon estadísticas descriptivas para evaluar las percepciones de los estudiantes y pruebas no paramétricas a través de un modelo de análisis de diferencia de medias para comparar el resultado entre las universidades. Resultados: la percepción de las dimensiones de calidad (Ẋ= 12,51) y eficacia (Ẋ=6,06) muestran una postura indecisa en general. En la fiabilidad (Ẋ=6,99), los alumnos estuvieron de acuerdo. Las dimensiones de preferencia-experiencia (Ẋ=10,649) y la de accesibilidad (x=7,01), colocan a los alumnos en el grupo de indecisos. En la comparación de medias de la escala de percepción de EFG (prueba t de estudent), la universidad pública presentó una media baja (ẋ=24,72), mientras que en el grupo de universidades privadas fue mayor (ẋ=26,06). En cuanto al uso de EFG, la universidad pública presentó una media ẋ=38,22, mientras que el grupo de universidades privadas fue menor (ẋ=36,70). Conclusiones: se requiere incluir en los contenidos curriculares de los futuros profesionales de la medicina, mayor información sobre calidad, seguridad y eficacia de las EFG, lo que contribuirá a elevar el nivel de confianza en su prescripción.

Los helmintos transmitidos a través del suelo pueden afectar el desempeño educativo y desenvolvimiento normal de los niños. Objetivo: comparar cinco técnicas coproparasitológicas para el diagnóstico de geohelmintos intestinales en niños lambayecanos. Métodos: estudio descriptivo de corte transversal. Se recolectaron 150 muestras de materia fecal de niños que residían en los distritos de Túcume y Lambayeque en el departamento de Lambayeque (Perú), durante el año 2021. Los niños y niñas tenían entre 4 y 12 años de edad. Previo a la recolección, se les explicó a los padres de familia y apoderados de los menores las condiciones preclínicas adecuadas. Se calculó la sensibilidad, especificidad, concordancia, valor predictivo positivo y negativo de las técnicas de Baerman, sedimentación rápida, Willis Molloy, Sheathers Sugar y examen directo de heces. Los padres y apoderados autorizaron la participación de los menores en el estudio. El estudio contó con la aprobación del comité de ética de la Universidad Nacional de Jaén. Resultados: la prevalencia geohelmintos intestinales fue del 20,7%, 19,3% y 18,0% con las técnicas de Baerman, sedimentación rápida y examen directo, respectivamente. Además, las técnicas de Baerman y de sedimentación rápida reportaron mayor sensibilidad, especificidad, valor predictivo positivo y negativo. Se obtuvo alto índice de concordancia para las técnicas de Baerman (0,894) y sedimentación rápida (0,891). Conclusiones: las técnicas de Baerman y de sedimentación rápida permitieron mayor recuperación de parásitos, respecto al examen directo. Además, las especies de geohelmintos intestinales más identificadas en niños lambayecanos fueron Ascaris lumbricoides, Hymenolepis nana y Ancilostomideos.

Una de las causas de la disminución de la visión es la catarata. El tratamiento es la extracción del cristalino opaco con reemplazo por un lente intraocular (LIO). La opacidad de cápsula posterior (OCP) es una complicación frecuente a largo plazo. Las modificaciones en el diseño del LIO tanto del material y la forma tienen mayor importancia para prevenir la OCP. Como tratamiento está la capsulotomía neodimio YAG láser. Objetivo: identificar la OCP relacionado con el tipo de LIO implantado en pacientes pseudofáquicos en la FBO, entre el periodo de marzo del 2019 hasta febrero del 2022. Métodos: estudio observacional,tipo analítico,subtipo cohorte histórica, retro-prospectiva y longitudinal, con enfoque de análisis estadístico de tipo cuantitativo. Resultados: predominó el género femenino con un 60% y un 40% representaba al masculino; un 60,3% del total tenían entre 65 a 80 años. La OCP en los 3 tipos de lentes intraoculares (acrílico y PMMA) ocasionó una disminución en la agudeza visual: el 37%, predominó, por el LIO hidrofóbico, 36% por el LIO PMMA y destacamos que el 27% fue por el LIO hidrofílico. La incidencia de OCP a 5 años fue del 32%. No se registró ningún efecto adverso en nuestro estudio. Conclusiones: la OCP provoca una baja de agudeza visual leve a moderada en los 3 tipos de LIOs; con un mínimo predominio de BAV leve para el tipo de LIO hidrofóbico comparado con el hidrofílico. Además después de la capsulotomía un gran porcentaje tiene entre 20/20 a 20/25 de AV mejor corregida.
Declaración de Cochabamba 2023 a propósito de la estrongiloidiasis, contra el microgusano del barro: es hora de actuar
Authors: Gétaz Laurent

El quinto congreso internacional de infectología se celebró del 15 al 17 de febrero de 2023 en Cochabamba, en el que se organizó un simposio sobre la estrongiloidiasis sobre el tema: “Es hora de actuar”. Es en esta ciudad de los valles interandinos, situada a 2.500 metros, con un clima templado, que se demostró por primera vez que este parasito tropical y subtropical se transmite también a una altitud tan elevada. La estrongiloidiasis, causada por el Strongyloides stercoralis, o más simplemente denominado “microgusano del barro”, es la helmintiasis intestinal más frecuente y grave en las regiones de Bolivia donde se investigó. La estrongiloidiasis, una de las enfermedades tropicales desatendidas más olvidadas, suele permanecer paucisintomática durante décadas en personas inmunocompetentes, pero provoca hiperinfestaciones parasitarias con altas tasas de mortalidad en individuos inmunodeprimidos. Las larvas se multiplican en el intestino, atraviesan la pared intestinal diseminándose a todos los órganos, y transportando en los vasos sanguíneos bacterias fecales, causando sepsis severa. Los corticosteroides, aun prescrito a corto plazo, son uno de los principales factores de riesgo de progresión a síndrome de hiperinfestación y estrongiloidiasis diseminada.Estos últimos años, se ha demostrado que la estrongiloidiasis es altamente endémica en Bolivia: 20% de las personas en alto riesgo de complicaciones son infectados en los departamentos de Cochabamba y Santa Cruz. Se demostró la presencia del microgusano del barro también en el Chaco y en el departamento de La Paz. En otras regiones faltan datos epidemiológicos.La enfermedad afecta a las personas que viven en las regiones endémicas. Pero también debido a las migraciones internas, las personas que viajan o trabajan en regiones endémicas pueden infectarse y quedar infectadas de por vida cuando regresan a regiones del Altiplano.La falta de sensibilidad de las pruebas coprológicas habituales ha contribuido a mantener esta enfermedad desatendida. Para diagnosticar este parásito, deben combinarse técnicas específicas de análisis de heces, como la técnica de Baermann, y la serología. Para la técnica Baermann, todo el equipo necesario está disponible y se fabrica en Bolivia. Para el reto del tratamiento, se ofrece una solución muy accesible: la ivermectina es el antiparasitario de primera elección. Es un medicamento barato, eficaz, disponible en Bolivia y con muy pocos efectos secundarios cuando se prescribe a la dosis adecuada.Participantes en la mesa redonda, implicados desde varios años en la mejora del conocimiento de esta enfermedad en Bolivia, y participantes al simposio, son signatarios de esta declaración, que propone un planteamiento en 4 etapas que ayudará a lograr el objetivo del control de la estrongiloidiasis.
