Background: Accuracy of molecular tools for the identification of parasites that cause human cutaneous leishmaniasis (CL) could largely depend on the sampling method. Non-invasive or less-invasive sampling methods such as filter paper imprints and cotton swabs are preferred over punch biopsies and lancet scrapings for detection methods of Leishmania based on polymerase chain reaction (PCR) because they are painless, simple, and inexpensive, and of benefit to military and civilian patients to ensure timely treatment. However, different types of samples can generate false negatives and there is a clear need to demonstrate which sample is more proper for molecular assays. Methodology: Here, we compared the sensitivity of molecular identification of different Leishmania (Viannia) species from Peru, using three types of sampling: punch biopsy, filter paper imprint and lancet scraping. Different composite reference standards and latent class models allowed to evaluate the accuracy of the molecular tools. Additionally, a quantitative PCR assessed variations in the results and parasite load in each type of sample. Principal findings: Different composite reference standards and latent class models determined higher sensitivity when lancet scrapings were used for sampling in the identification and determination of Leishmania (Viannia) species through PCR-based assays. This was consistent for genus identification through kinetoplastid DNA-PCR and for the determination of species using FRET probes-based Nested Real-Time PCR. Lack of species identification in some samples correlated with the low intensity of the PCR electrophoretic band, which reflects the low parasite load in samples. Conclusions: The type of clinical sample can directly influence the detection and identification of Leishmania (Viannia) species. Here, we demonstrated that lancet scraping samples consistently allowed the identification of more leishmaniasis cases compared to filter paper imprints or biopsies. This procedure is inexpensive, painless, and easy to implement at the point of care and avoids the need for anesthesia, surgery, and hospitalization and therefore could be used in resource limited settings for both military and civilian populations. Author summary: Human cutaneous leishmaniasis affects low-income populations living in places far from health services. The early sampling and detection of the parasite are necessary for timely treatment, however there are no uniform sampling criteria, thus the sensitivity of molecular tests may vary due to various factors such as the type of sample, the time of the disease and the parasite load in the lesion. In this study, we compared the performance of three sampling methods for molecular identification of the genus and Leishmania (Viannia) species in Peru. Several analytical methods, including composite reference standards and latent class models, suggested that lancet scraping might be the best approach for parasite genus detection by kDNA-PCR and for parasite species determination by FRET probes-based Nested Real-Time PCR.

Objectives: To determine the frequency of publication of scientific articles by thesis advisors of the School of Medicine of a private University in Lima, Peru. Methods: Cross-sectional and descriptive study. We search for papers using Google Scholar, Medline, and Scopus. The frequencies and percentages of the variables were calculated. Results: Out of 19 advisors, 63% of them had ever published an article in their life, and 53% had ever published an original article. 26% and 21% have published an original paper in Scopus and Medline in the last five years, respectively; while only 5% published an original article during the previous two years in those databases. Just one teacher (5.3%) was registered in REGINA. Conclusions: The publication rate in recent years of the thesis advisers of a School of Medicine of a private University of Lima is poor.

This paper navigates the complex roles that the Catholic Church assumes in fragile democracies, exploring whether it functions as an influencer, a moral guide, or a judge in shaping public policies and societal values using the Peruvian context as a focal reference. The authors begin by providing an overview of the global religious landscape, highlighting the diverse and polarized trends within the ecclesial institution. In the second part of this paper, this study delves into the homilies of two influential Peruvian prelates, Mgr. Cipriani and Mgr. Castillo, representing opposing theological currents within the Catholic Church, offering a pertinent exploration of how religious institutions engage with evolving international and local trends in the context of democracy.

Background: Peru is facing a double burden of malnutrition (DBM), characterized by the co-existence of undernutrition and overnutrition. Double-duty actions that concurrently target common drivers of undernutrition and overnutrition, while ensuring no unintended side effects, are recommended to effectively address the DBM. To understand these complex common mechanisms and design context-specific double-duty actions, there is a need for participatory systems approaches. This paper provides a case study of applying a community-based system dynamics approach to capture stakeholder perspectives of food system drivers of the DBM in two regions in Peru. Methods: We implemented a multi-stage community-based system dynamics approach, which included processes for research capacity building for systems approaches, and the designing, piloting, and implementation of stakeholder workshops. A total of 36 stakeholders, representing diverse perspectives, participated in five group model building workshops. Stakeholder views are presented in a causal loop diagram that showcases the feedback mechanisms between key food system drivers of overweight and stunting in Peru. Results: The causal loop diagram highlights that prioritization of undernutrition over overnutrition in the policymaking process, due to Peru's historically high levels of undernutrition, may undermine action against the DBM. It also describes potential mechanisms of unintended impacts of undernutrition policies on the DBM in Peru, including impacts related to within-family distribution and quality of food provided through food assistance programs, and unintended impacts due to regional dynamics. Conclusions: This paper highlights the importance of a participatory approach to understand local needs and priorities when recommending double-duty actions in Peru and shares practical methodological guidance on applying participatory systems approaches in public health.

As arid lands expand across the globe, scholars increasingly turn to the archaeological record for examples of sustainable farming in extreme environments. The arid north coast of Peru was the setting of early and intensive irrigation-based farming; it is also periodically impacted by sudden, heavy rainfall related to the El Niño Southern Oscillation (ENSO) phenomenon. While the sociopolitical effects, technologies, and engineering expertise of these irrigation systems have been thoroughly examined and theorized, little is known about how farmers managed periods of water stress. The aim of this study is to test whether arid zone farming was supported by hybrid, intermittent flood and perennial water source systems in the prehispanic past. An arroyo in the Chicama Valley was selected for preliminary data collection, and these data are presented here: (1) drone photography of the arroyo capturing the aftermath of a recent (2023) rain event; and (2) potassium (K) soil test kit results from samples collected near suspected prehispanic check dam features in the same area. The paper combines these data with comparative examples from the literature to suggest that the prehispanic features functioned as water-harvesting infrastructure. The paper concludes that sustainable, arid zone farming can be supported by hybrid, intermittent flood and perennial water source systems. [ABSTRACT FROM AUTHOR]

This paper is an in-depth study that starts from a preliminary one, where we surveyed 141 ranchers from the town of Coto-Coto in Peru to obtain as much information as possible about the relationship between two economic variables, Activity Cost and Financial Management. Furthermore, we study the correlation of the first one of them with three other economic variables. To do this, we process the survey data using logical operators with the support of the plithogenic statistics theory. These results given in the form of plithogenic values are logically aggregated and were converted to crisp values and studied through the use of statistical tools, specifically Kendall's Tau b. The study of economic variables within the field of cattle farming is of great importance because it allows us to improve the productivity of this economic sector, which is also part of the most accepted human diet worldwide. A substantial advantage in the use of plithogeny is that linguistic values that are more natural for livestock farmers were processed, in addition, uncertainty and indeterminacy were taken into account by the use of neutrosophic numbers.

Activity Cost and Financial Management are two variables of vital importance in livestock production. This paper aims to measure the relationship existing between these two variables within the production of beef cattle in the Coto-Coto Chilca Livestock Fair in Peru. To do this, we selected 141 ranchers from the area to give their opinions regarding the behavior of these two variables. The data were represented with the help of an Indeterminate Likert Scale, to capture the uncertainty and indeterminacy of the respondents' opinion. Survey results were compared for the two variables using a measure of neutrosophic similarities. Neutrosophic similarities are used to measure the degree of similarity between two neutrosophic sets measured in certain aspects. [ABSTRACT FROM AUTHOR]

Noncommunicable diseases and mental health conditions (referred to collectively as NMHs) are the greatest cause of preventable death, illness, and disability in South America and negatively affect countries' economic performance through their detrimental impacts on labor supply and capital investments. Sound, evidence-based policy-making requires a deep understanding of the macroeconomic costs of NMHs and of their distribution across countries and diseases. The paper estimates and projects the macroeconomic burden of NMHs over the period 2020–2050 in 10 South American countries. We estimate the impact of NMHs on gross domestic product (GDP) through a human capital-augmented production function approach, accounting for mortality and morbidity effects of NMHs on labor supply, for the impact of treatment costs on physical capital accumulation, and for variations in human capital by age. Our central estimates suggest that the overall burden of NMHs in these countries amounts to $7.3 trillion (2022 international $, 3% discount rate, 95% confidence interval: $6.8–$7.8 trillion). Overall, the macroeconomic burden of NMHs is around 4% of total GDP over 2020–2050, with little variation across countries (from 3.2% in Peru to 4.5% in Brazil). In other words, without NMHs, annual GDP over 2020–2050 would be about 4% larger. In most countries, the largest macroeconomic burden is associated with cancers. Results from the paper point to a significant macroeconomic burden of NMHs in South America and provide a strong justification for investment in NMH prevention, early detection, treatment, and formal and informal care.

Background. Traditional detection of Leishmania from ulcers involves collection of invasive specimens that cause discomfort, require technical expertise, and carry risks of invasive procedures. We compared traditional diagnostic methods with a molecular noninvasive filter paper-based method for the diagnosis of cutaneous leishmaniasis. Methods. Consecutive patients presenting to the Leishmania Clinic at Hospital Nacional Cayetano Heredia were enrolled. Polymerase chain reaction (PCR) was performed on lesion scrapings, aspirates, and filter paper impressions. The reference standard was any 2 of 5 tests positive: smear, aspirate culture, invasive-specimen PCR (scrapings and aspirates), filter paper PCR, and leishmanin skin test. Outcome measures were sensitivity and specificity. Leishmania speciation was performed by PCR--restriction fragment length polymorphism (RFLP) of positive specimens. Results. Forty-five patients with 66 lesions were enrolled. Of 52 lesions diagnosed as cutaneous leishmaniasis, 50 were positive by PCR of invasive specimens versus 48 by PCR of filter papers (P = .930). Sensitivity and specificity of PCR on invasively obtained specimens were 94.2% (95% confidence interval [CI], 87.9%-100%) and 92.9% (95% CI, 79.4%-100%). Sensitivity and specificity of filter paper PCR were 92.3% (95% CI, 85.1%-99.5%) and 100%. Culture, smear, and leishmanin skin test all had inferior sensitivities, compared with PCR of invasive or noninvasive specimens (P < .001). Of 50 specimens positive by PCR, 19 had sufficient DNA for PCR-RFLP analysis. Conclusions. Filter paper PCR constitutes a sensitive and specific alternative to traditional diagnostic assays. This novel, rapid, well-tolerated method has the potential for widespread use in the field and in pediatric populations where traditional specimen collection is most difficult to perform, and can potentially be used for rapid species identification.

Objective: To determine the characteristics of the original papers about the plants properties published in Peruvian medical journals. Material and methods. We reviewed the bibliographic databases of SciELO Peru and SISBIB for the period 2004-2008. Results. We found 825 original papers in 14 journals, but only 45 were included to the study. The number of the included original papers by year was 3 (2004), 5 (2005), 9 (2006), 13 (2007) y 15 (2008). The journals that published the highest rate of original papers about plants were journals from medical faculties Rev Med Vallejiana (33%), Horizonte Médico (29%) y An Fac Med (13%). The institutions that developed more studies were Universidad. Nacional Mayor de San Marcos (45,5%), Universidad de San Martín de Porres (22%) y Universidad Nacional de Trujillo (13%). from 226 authors, 11 were the most productive authors with the 22,1% of the total production. from 57 studied plants, the most investigated were Lepidium sp. (maca), Croton palanostigma (sangre de grado), Calophyllum brasiliense (lagarto caspi) and Smallanthus sonchifolius (yacón). The potential uses of the plants more researched were nutritional, antineoplastic, antioxidative, hypoglycemic and arterial hypotensive. There were only six (13,3%) clinical studies and the rest was experimental or biochemical. Conclusions. The published scientific medical production related to the plant properties is scanty but growing, mainly done in the public and private universities with almost null participation of the private enterprise. There is an elite of highly-producing authors. [ABSTRACT FROM AUTHOR]

The primary purpose of this paper is to present an actual case of a Peruvian SME which applied IFRS accounting standards – specifically, IAS 41 for consumable biological assets – to reflect its financial situation more accurately as an alternative to legal and tax regulations applying historical cost, which Peruvian SMEs more commonly use for the preparation of financial statements. Primary data were gathered through interviews and observation at the SME studied. This forestry-industry SME in question tried unsuccessfully to get financing from banks, even presenting complementary information regarding the calculation of biological asset values according to IAS 41. Failing this, it turned to seeking funding from private long-term investors, eventually succeeding in obtaining long-term financing from a new strategic investor. The significance of this paper is that it presents evidence of the advantages for companies (specifically agriculture-related companies) that comply with IFRS in a country where historical cost-based tax rules are traditionally applied for accounting purposes. Other SMEs can similarly improve the likelihood of obtaining new capital from potential investors by complementing the information provided in financial statements with detailed data regarding fair value calculation of biological assets.

This paper presents the results of seven deep learning models for prediction of research project execution in graduates from a public university in Peru. The deep learning models implemented are non-hybrid: Deep Neural Networks (DNN), Long Short-Term Memory (LSTM), Gated Recurrent Unit (GRU), Convolutional Neural Networks (CNN) and, hybrid: CNN+GRU, CNN+ LSTM and LSTM+GRU. Since most of the dataset prediction features are of the nominal type (true or false), this paper proposes a simple novel data augmentation technique for this type of features. Taking as inspiration the input data type of a neural network, the proposal data augmentation technique considers nominal features as numeric, and obtain random values close to them to generate synthetic records. The results show that most of deep learning models with data augmentation significantly outperform models with just class balancing in terms of accuracy, precision, f1-score and specificity, being the main improvements of 17.39%, 80.00%, 25.00% and 20.00% respectively.

Pharmaceutical sector corruption undermines patient access to medicines by diverting public funds for private gain and exacerbating health inequities. This paper presents an analysis of UN Convention Against Corruption (UNCAC) compliance in seven countries and examines how full UNCAC adoption may reduce corruption risks within four key pharmaceutical decision-making points: product approval, formulary selection, procurement, and dispensing. Countries were selected based on their participation in the Medicines Transparency Alliance and the WHO Good Governance for Medicines Programme. Each country’s domestic anti-corruption laws and policies were catalogued and analysed to evaluate their implementation of select UNCAC Articles relevant to the pharmaceutical sector. Countries displayed high compliance with UNCAC provisions on procurement and the recognition of most public sector corruption offences. However, several countries do not penalise private sector bribery or provide statutory protection to whistleblowers or witnesses in corruption proceedings, suggesting that private sector pharmaceutical dispensing may be a decision-making point particularly vulnerable to corruption. Fully implementing the UNCAC is a meaningful first step that countries can take reduce pharmaceutical sector corruption. However, without broader commitment to cultures of transparency and institutional integrity, corruption legislation alone is likely insufficient to ensure long-term, sustainable pharmaceutical sector good governance.

This paper aims to investigate whether social skills are a factor related to emotion management since inadequate emotion management is causing mental illnesses in this century, such as stress and depression. The objective was to determine the relationship between social skills and emotional management in students at the National University of Central Peru. To estimate social skills, the scales proposed by the Technical Team of the Department of Mental Health Promotion and Prevention of Psychosocial Problems of Peru were applied to a random sample of 184 from a population of 352 students. The variable of adequate management of emotions was measured using an Indeterminate Likert Scale since we consider that emotion has multiple components and therefore it is more precise to measure it when all the components are taken into account at the same time. To process the collected data, plithogenic statistics were applied that allow the study of events of a multivariate nature in an indeterminate framework. [ABSTRACT FROM AUTHOR]

The extraction of essential oils in the world is widely used to combat various diseases, and also helps for giving a good taste to food (flavoring condiments) and cosmetics that do not pollute the environment or generate chemicals. Peru is in the top 10 countries with the greatest biological diversity in the world, having an approximate 10% of world flora and endless endemic species, also valuing the citrus fruits having productive of orange, lime, grapefruit, tangerine, and tangelo. Therefore, processes are analyzed and a model for the extraction of essential oil from citrus fruits is developed, through the design of an industrial-scale steam extractor, which establishes the automation of the filling and emptying of the distiller to obtain better results and also automates a closed-loop control for refrigeration, to help the operator to control and supervise the process of refrigeration and water filling using a control panel. The distillation process was analyzed where an average of 1% to 5% of essential oil of citrus fruits was obtained and the development of a control for the supervision of the filling and emptying of the water was analyzed. In this paper we introduce a Neutrosophic (Indeterminate) Control System model based on the well-known Fuzzy Control Systems models, especially Mamdani's. It is applied in the process of automating the extraction of essential oil from citrus fruits. An Indeterminate Control System, like its similar Fuzzy Control System, makes it possible to control the oil production process with the help of natural language. The advantage of the Indeterminate Control System is that it explicitly considers indeterminacy due to the non-homogeneity of the parameters within the system, thus it is more accurate.

This paper presents an Accounting and Valuation (AV) method within the scope of Integrated Resource Planning (IRP) to analyze social impacts when implementing new energy resources. The method is based on a critical analysis from existing assessments regarding the IRP and its design is based on algorithms that convert qualitative information of social attributes into absolute values. These values feed the subsequent stages of the IRP to select the best energy resource (among available options) to be implemented. The method has been applied and tested as a pilot case in a rural region in Peru. This work provides extremely valuable information for decision-makers to assess, with real and quantitative data, investment decisions regarding energy planning. [ABSTRACT FROM AUTHOR]

The present paper presents the analytical study of an unusual Peruvian 1899 dinero coin whose authenticity has been questioned since the 1970's. This coin, which is present in some numismatic collections although there is no record of having been minted officially, has been characterized using non-destructive techniques such as X-ray fluorescence (XRF), scanning electron microscopy coupled with energy dispersive spectroscopy (SEM–EDS), and X-ray diffraction (XRD). Results are consistent with a cast counterfeit coin made at the turn of the 19th and 20th using a copper base alloy that was silver-platted to pass unnoticed among the public. The alloy used, generally known as german silver, was common for counterfeits in North America and Europe in that period. The historical reasons for the appearance of this unexpected coin in Peru during a time of economic difficulties, where the public experienced a shortage of small-change coins, are briefly outlined.

Objectives: The present paper aims to characterize the Angiotensin-converting enzyme (ACE) genotype, with particular emphasis on its association with arterial oxygen saturation, arterial blood pressure, hemoglobin [Hb] concentration, and ventilatory measures among the Tawang Monpa, a high-altitude native population of the Eastern Himalaya, India. Methods: A cross-sectional sample of 168Monpa participants from Tawang town, Arunachal Pradesh, India, was selected who live at an altitude of ∼3,200 meters (m) above sea level. For each participant, height, weight, and skinfold thickness were measured, based on which body mass index (BMI, kg/m2) and percentage of body fat (%BF) were calculated. Physiological measures, such as the transcutaneous arterial oxygen saturation (SaO2), hemoglobin [Hb] concentration, forced vital capacity (FVC), forced expiratory volume in 1-second (FEV1), and systemic arterial blood pressure were measured. First, the peripheral venous blood samples (four ml) were drawn, and then white blood cells were separated for the ACE genotyping of each participant. Results: Unlike high-altitude natives from Peru and Ladakh, who exhibit high frequencies of II homozygotes, the Tawang Monpa shows a significantly high frequency of ID heterozygotes (p<0.0001). In addition, no significant association was identified between ACE gene polymorphism and arterial blood pressure, oxygen saturation at rest, vital capacity, or [Hb] concentration. Discussion: The results suggest that the association of the ACE gene with resting SaO2 is inconsistent across native populations living under hypobaric hypoxia. Further, ACE I/D gene polymorphism may not be under natural selection in specific native populations, including Tawang Monpa, for their adaptation to high-altitude hypoxia. [ABSTRACT FROM AUTHOR]

Airbnb is a worldwide tourism phenomenon that affects local commerce. In Peru, this type of service has increased. Its followers value the stay and the benefits of the place and write about it to recommend or advise against it. The aim of this paper is to analyze the discourses through linguistic strategies of guests staying in Lima-Peru. Methodologically, a corpus consisting of 91 textual samples has been collected, which are frequently used and coming from guests in the most touristic districts of Lima. It is concluded that guests generally create discourses about their stay, comfort and safety. In doing so, they put the reputation of the hosts at stake and make the published information useful for potential tourists. [ABSTRACT FROM AUTHOR]

The paper points out the quinoa trade between Peru and the European Union regarding selected economic issues of quinoa production and prices in Peru and import into the EU. Quinoa is known as superfood due to the high level of protein, fibre, micronutrients, and all amino acids. This caused an increased interest in its consumption in the EU which resulted in rising prices. High quinoa prices have motivated farmers in different parts of the world to try producing quinoa that is traditionally home to areas in South America. The increase in the quantity of quinoa offered led to its fall in prices. Quinoa price volatility creates uncertainty for Peruvian farmers and traders, for whom quinoa is one of the main commodities. The article focuses on the development of quinoa production and prices in Peru, a country that is one of the main producers of quinoa in the world at a time when quinoa has become a popular superfood. During this period, imports of quinoa into the EU, which is a major trading partner of Peru in relation to the quinoa, also increased. Based on the assessed economic situation in the quinoa market between Peru and the EU, the authors of the article are looking for tools that could make it easier for Peruvian farmers to be successfully established in the EU market, despite the high interest in growing this commodity in different parts of the world.

This paper aims to make a proposal to govern the Peruvian State under the umbrella of management cybernetics, following the paths of the viable system model (VSM), proposed by Prof. Stafford Beer, enriched with other soft and hard systemic methodologies and technologies, to cover the soft and hard issues that are part of the complex Peruvian reality at different levels of recursion. For doing this, four defined perspectives were adopted to understand the complexity of Peru: the sectoral view, the regions view, the river basins view and the macroregions view. Peru is seen as a system in focus, defining, for each of these four perspectives, the five systems that VSM has. The application of the VSM in each perspective serves to apply it in two modes: diagnosis and design, according to the respective perspective. Then an integrative analysis and reflection is done considering the four perspectives, to analyze the viability of the VSM approach in the governance of the Peruvian State to establish some conclusions and recommendations in relation to the proposal, appearing at the end of the paper.

• Combined with field test and numerical simulation, the rock damage characteristics around peripheral hole are fully analyzed. • The influence of explosive spacing, blasthole spacing and smooth blasting layer thickness on different damage indexes of rock mass is analyzed, and the influence of boundary conditions is discussed. • Considering the influence of explosive spacing and blasthole spacing, a mathematical model is established firstly to predict the rock damage range and applied to engineering practice. • The research method in this paper provides a solution to similar engineering problems. The control of overbreak in blasting excavation is a significant technical challenge and a subject of extensive research in the field of engineering. This study examines the damage characteristics of the surrounding rock in a tunnel section through blasting test and numerical simulation conducted as part of the San Gavan diversion tunnel project in Peru. The orthogonal test of peripheral holes under the influence of explosive spacing, blasthole spacing and smooth blasting layer thickness was designed to analyze the characteristics of rock damage under different parameter combinations and the influence of various factors on rock damage. Based on the USBM formula, this paper deduces a mathematical model considering blasthole spacing and explosive spacing to predict the rock damage range. The main conclusions are as follows: on the tunnel section, the average damage range of vault and arch springer is slightly larger than that of spandrel and haunch. For a single blasthole, the rock damage range in different sections is: explosive > air > stem, and the degree of rock damage at the bottom of blasthole is the highest. Smooth blasting layer thickness has a significant effect on rock damage rate on the side of non-reflect boundary. When smooth blasting layer thickness is 45 cm and 55 cm, the boundary conditions of numerical model have a significant effect on the rock damage. The reflection of blasting stress wave on the free surface leads to the further increase of rock damage range. The blasthole spacing and explosive spacing have a significant effect on rock damage range on the side of non-reflect boundary, and both show a negative correlation. Based on the prediction model of rock damage, the combination of peripheral hole parameters satisfying the standard is obtained, which provides guidance for blasting design. [ABSTRACT FROM AUTHOR]

This paper deals with the origin of the theory of español costeño and español andino, focusing on yeísmo and lleísmo, on the basis of which the theory was developed at the turn of the 19th century. I argue that the early conception of español costeño and español andino has strongly influenced the kind of research we have been conducting about the geographic varieties to this day. The aim of this study therefore, is to sharpen our understanding of the former zeitgeist of research and to stimulate further 'big data'-based studies on español costeño, español andino and español amazónico, the third Peruvian geographic variety, traditionally neglected by linguistic research.

Peru is an emerging nation with a nonuniform development where the growth is focused on some specific cities and districts, as a result there is serious economic inequalities across the country. Despite the poverty in Peru has declined in the last decades, there is still poor districts in risk to become extremely poor, even in its capital, Lima. In this context, it is relevant to study the incidence of extreme poverty at district levels. In this paper, we propose to estimate the quantiles of the incidence of extreme poverty of districts in Lima by using spatial quantile models based on the Kumaraswamy distribution and spatial random effects for areal data. Furthermore, in order to deal with spatial confounding random effects we used the Spatial Orthogonal Centroid "K"orrection approach. Bayesian inference for these hierarchical models is conveniently performed based on the Hamiltonian Monte Carlo method. Our modeling is flexible and able to describe the quantiles of incidence of extreme poverty in Lima. [ABSTRACT FROM AUTHOR]

This study aims to document the diversity of medicinal plants used by the Cashinahua people (also known as Huni Kuin) of the Curanja River, as well as describe and compare their uses with pharmacological and phytochemical records from previously published studies. The ethnic has been studied to a limited extent from an ethnobotanical perspective. The study area is located in the Ucayali region, eastern Central Amazon, where ancestral knowledge is preserved due to the limited accessibility of the region. Between November 2010 and June 2015, a total of 11 months were spent on the survey, which included a short-term visit to complete voucher specimen collection and taxonomic identification. We conducted semi-structured interviews with 10 Cashinahua traditional healers and 10 midwives. Vernacular names, ethnomedicinal uses, plant parts used and forms of preparation and administration were recorded. Ethnopharmacological, pharmacological and phytochemical uses were checked through survey of the previously published papers indexed on Web of Science databases between 2018 and 2022. We obtained data on 467 plant taxa, among which we highlighted 79 species unreported or rarely cited for medicinal use or phytochemical analysis. These species were spread over 60 genera and 42 botanical families, with Acanthaceae being the most represented. Leaves were used the most frequently (93.56%). Among the 79 species, the most reported therapeutic activities involved pregnancy and birth disorders (13.84%), followed by poisonings, infections and infestations. The predominant application form was external (87%). Our study indicates that there are locally valuable species that have not yet been studied for their medical potential. [ABSTRACT FROM AUTHOR]

In this paper we describe the vegetation of Yura and its surroundings using the Braun-Blanquet phytosociological method. As a result, we report 3 new associations (Equiseto gigantei-Escallonietum angustifoliae, Pohlio longicollis-Rhodoscirpetum yurensis and Atriplici myriophyllae-Mesembryanthemetum crystallini) and 3 new alliances (Muehlenbeckio fruticulosae-Helogynion stramineae, Polypogono interrupti-Pohlion longicollis and Atriplici myriophyllae-Mesembryanthemion crystallini) of base-rich saline environments. In addition, Lycio distichi-Helogynetum stramineae is presented as a corrected name and the area of the Schino mollis-Prosopidetum calderensis association is extended to the NW. In sum, nine plant communities have been observed, among which the Pohlio longicollis-Rhodoscirpetum yurensis association is worth highlighting, as it presents a recently described Cyperaceae, associated with a bryophyte possibly recorded for the first time in southern Peru at a much lower altitude than known.

This paper aims to compare the effect of ration supplementation with breadfruit (Artocarpus altilis) flour and plantain (Musa paradisiaca) flour at different concentrations on weight gain in Hybrid turkeys at the farm production of Canchán, Peru during 2021. An experimental study was carried out consisting of a total of 100 Hybrid turkeys; to which breadfruit flour and banana flour were supplied, in: 10% and 20% to the turkey ration. The experimental units were randomly distributed into 5 groups where it can be observed that the greatest weight gain was in group 1 with the addition of 10% breadfruit flour. Using the analysis of variance (ANOVA), statistically significant differences were found between these study groups (p = 0.005). It was possible to conclude that breadfruit meal has a greater effect than plantain meal on weight gain in Hybrid turkeys at the Canchán production center. [ABSTRACT FROM AUTHOR]

Our pilot project, Son Mis Datos (It's My Data), is among several initiatives that have arisen over the past few years to address the need for personal data literacy in an era of increasing datafication, platformization, algorithmic decision making and digital transformation. The vast majority of these projects have emerged in Europe, North America and Australia, often in the wake of the Cambridge Analytica scandal and regulatory initiatives such as the Global Data Protection Regulation (GDPR). Given this period of experimentation with community intervention, there is little clarity about what constitutes a successful personal data literacy initiative, particularly for the Latin American context, given its particular experience with digital transformation, unique tradition of communications theory, and position within the global economy. In this paper we explore and critique the goals of other personal data literacies as a foundation for our own set of evaluative criteria. We then turn these criteria on the Son Mis Datos initiative to explore the assumptions, successes and shortcomings of our initiative. The paper concludes with a set of recommendations for how to pursue personal data literacy work that is culturally relevant and grounded in the needs and perspectives of local communities.

Gender inequality has not been oblivious to science, where the under-representation of women in the academic scope is a concern. This is a problem that requires in-depth study, especially in careers with high percentages of women such as psychology and regions such as Latin America where there is a considerable proportion of female scientific psychologists. Despite this scene, the feminine production is known to present an increase; however, it is still lower than the masculine one. This shows that women are under-represented in leadership positions, hiring and applying for grants, and financing of research projects in public health and epidemiology. Likewise, review studies on female production in psychology are scarce in Peru and Latin America. The objective of this research is to characterize the production of women researchers in psychology by type of research, area of application, leadership and subject matter. For such objectives, a total of 149 papers published by 14 women researchers recorded in Peru's National Registry of Science, Technology and Technological Innovation (RENACYT) were analyzed. Four psychologists were excluded because they did not have their scientific production declared; in addition, repeated documents and those which did not correspond to scientific documents, such as congress summaries, papers in non-indexed journals and those excluded from any database were also excluded under the PRISMA's recommendations. The results show a greater quantity of co-authorships (60.4 %), studies with empirical designs (79.2 %), of associative objective (36.2 %), correlational strategy (21.5 %) and a greater quantity of papers in the clinical and health subfield (38.9 %) and education (38.3 %). As for the subject matter, clinical disorders (23.5 %) and cognitive processes (16.8 %) appear with greater frequency. Regarding these findings, there is scientific information evidencing that empirical designs are the most usual form of research, while the theoretical ones are the opposite; at least in Latin American. Furthermore, a ranking of the 100 most eminent psychologists of the 20th century only includes two women: Mary Ainsworth and Anna Freud, ranked 98th and 100th respectively. As for the fact of finding that more than 50 % of researchers occupy the position of co-author, previous studies show similar percentages in the health field indicating an increase from 50.3 % to 55.6 % in co-authorship. Finally, there is little scientific literature about the frequent topics studied by psychologists; therefore, these results are unprecedented; however, a search in Scopus by keywords reveals that HIV is the most studied topic in Peru; a variable located in the clinical and health subfield. Likewise, another variable that appears in the search is depression, that can be included in the topic of clinical disorders. Despite these results, the study has the following limitations: firstly, feminine scientific production can be studied from diverse sources such as review of publications in a journal, presentations at a congress, production in Scopus, which can cause difficulties in contrasting results. Secondly, there are no studies on thematic analysis, which does not allow comparison with previous research and suggests taking the findings with caution because it has a more exploratory connotation, so it is recommended to continue with this type of study. In conclusion, research psychologists carry out empirical studies framed in the analysis of the relationship between variables with a lesser predominance of theoretical and manipulative, quasi-experimental or single case studies. To a greater extent, the research is clinical and based on health. The women appear as co-authors in a large percentage of studies where the most frequent subject is clinical disorder.

The study describes and analyzes the state of research on cocoa cultivation in administrative and socioeconomic areas in Latin America during the last five years. The research is descriptive, for which we proceeded to identify the location of the research articles considering the following criteria: filter by publication, filter by keyword and filter by topic. The results allow us to observe that after a filtering of 50 articles, the database was made up of 31 papers. It was known that 74.42% of the publications are published in regional impact databases (Latindex, DOAJ, Scielo and Redalyc) and in a lower order with 22.58% in global impact databases (SCOPUS and WEB_OF_SCIENCE); Likewise, it was determined that the most frequent lines of research are that of productive processes of cocoa cultivation in Latin America in 70.97% and in 29.03% socioeconomic aspects; It was possible to show that Ecuador leads the investigations in this area by 54.84% and to a lesser scale countries such as: Colombia, Mexico, Peru by 22.58%; 12.90%; 9.68% on your order. It is concluded, despite the fact that important research contributions have been made in the production processes of cocoa; It is important to analyze the economic and financial part of this crop in order to provide the small and medium producer of this crop with strategies that help improve their quality of life.

The Regional Archive of Cusco in Peru guards valuable history collections with exceptional regional and international value dating from the sixteenth century to the present. Historical manuscripts are part of the identity of all people; they constitute a tangible cultural heritage that must be studied, valued, and protected. In this sense, the objective of this research was to identify the chemical compositions of inks and paper, with the goals of setting the background of their originality, identifying relationships between them, and glimpsing antecedents that generated degradation due to the compositions of the inks. This study is the first of its kind in Peru and reveals the chemical elements present in the writing ink, the seal, and the paper of five documents from the late eighteenth and early nineteenth centuries. Duplicate in situ nondestructive analyses were carried out using a hand-held X-ray fluorescence spectrometer under ambient conditions in soil mode, configured with three sequential shots, and energies from zero to 40, 40, and 15 keV, respectively. The elements S and Fe were present as components of iron gall inks. Cu and Zn were less abundant; probably, they provided less corrosion and more color intensity to the inks. The minor elements Pb, As, and especially Ag in all manuscripts differentiate them from European inks of the same period. Additionally, the five documents reflect the same elemental compositions but with different concentrations. This could mean that writers used local raw materials and Spanish ink recipes. Finally, the analyses of standard reference material, SRM 1646a and SRM 196b, gave results with acceptable precision. [ABSTRACT FROM AUTHOR]

This paper is dedicated to study the forest and the impact of its use in the native community of Chamiriari in the province of Satipo, Peru. The adequate forestry use of the forests in the area would allow the efficiency in the timber industry and therefore mean an economic improvement, in addition to reducing ecological damages and preserving the cultural wealth of the native Chamiriari people who inhabit the area. That is why the statistical study of how timber resources are exploited in this area of Peru was necessary. For this, plots that serve as a sample were randomly selected to study the trees distribution in Satipo. One drawback found is that due to the number of plots studied and the extension of them it is difficult to count exactly how many trees exist, even on how much land is not planted, that is why the technicians who carried out the data collection were asked to express the data in the form of intervals, where imprecision is included, but the accuracy is preserved. This way of representing the data needs to be processed with the use of Neutrosophic Statistics, which is the extension of the theory of classical statistics to cases where data or parameters are available in interval forms. The results obtained will make it possible to increase the efficiency of timber industry with a minimum of ecological damage and respecting the way of life of the Chamiriari community. It is the first time to the authors’ knowledge that a study of this kind has been carried out in the province of Satipo. We concluded that the studied plots which are “non-intervened” or with few of cut out trees, have more variety in tree quality and economical interest in comparison with the “intervened” plots.

The paper presents an integrated framework of success and failure factors of agricultural cooperatives and its applicability based on a review of recent literature and an illustrative case study. We identify six categories of success and failure factors: the societal environment, quality of management, strategy, member base, commitment, and product aspects. Contrary to expectations that failure factors mirror success factors, the framework shows that the two represent distinctive features in at least some of the distinguished categories. The analysis of an agricultural cooperative in Peru, selected and presented as an illustrative case study, shows the applicability of the framework for the analysis of success and failure factors of cooperatives.

The literature on Quechuan languages describes the enclitics =mi and =chi as markers of evidentiality, with the former indicating direct evidence and the latter marking conjecture or inference. In this paper, I argue that in Conchucos Quechua they can be better characterised as markers of two degrees of assertional force, which the speakers use for common ground management purposes. For this, I present an analysis of semi-controlled conversational data under the question-under-discussion model of discourse structure. Additionally, I offer a preliminary version of how these functions could be formalised in such a theoretical framework using the model of the Table. [ABSTRACT FROM AUTHOR]

This paper describes the traditional knowledge on the management of stingless bee colonies and the use of honey by Indigenous and non-Indigenous communities of the department of Loreto, in the Peruvian Amazon. Semi-structured interviews and collection of voucher bees were carried out from June to August 2016 and from November to December 2017. The informants were selected through intentional non-probabilistic sampling (snowball sampling). During the study, 21 communities were visited, of which some of the community members in thirteen communities kept stingless bees. A total of 17 species of stingless bees are reported as used in the communities for either rearing or harvesting of honey from the forest with Melipona eburnea being the most common species. The way communities classify, manage, and use bees depends on how they perceive these insects, informed by knowledge processed and incorporated from other communities. In these communities, they use honey and pollen, with honey being the main product. Fourteen health conditions are treated with honey, with the most treated conditions being related to respiratory ailments, fertility, and reproduction. The study provides a basis for incorporating stingless bees into conservation and sustainable production policies. [ABSTRACT FROM AUTHOR]

In this paper we develop a novel framework aimed to significantly reduce biases related to marine stratocumulus clouds in general circulation models (GCMs) while circumventing excessive computational cost requirements. Our strategy is to increase the horizontal resolution using a regionally refined mesh (RRM) over our region of interest in addition to using the Framework for Improvement by Vertical Enhancement (FIVE) to increase the vertical resolution only for specific physical processes that are important for stratocumulus. We apply the RRM off the coast of Peru in the southeastern Pacific, a region that climatologically contains the most marine stratocumulus in the subtropics. We find that our new modeling framework is able to replicate the results of our high-resolution benchmark simulation with much fidelity, while reducing the computational cost by several orders of magnitude. In addition, this framework is able to greatly reduce the long-standing biases associated with marine stratocumulus in GCMs when compared to the standard-resolution control simulation.

This paper studies the potential association between two geographic indicators, distance and altitude, with the Multidimensional Poverty Index (MPI) for 1,874 district in Peru by using the National Census of 2017. We investigate whether higher altitude or longer distance is associated with higher MPI values. For this purpose, we use the distance of each district to three different potential spaces of reference. First, we use the shortest distance to the metropolitan area of Lima; second, the shortest distance to the capitals of coastal departments; third, and finally, the shortest distance to the sea. We obtain three relevant results. First, we find evidence that altitude is statistically significant and positive associated with variation of MPI among districts. Second, the distance with respect to the sea appears to be more relevant to explaining differences in MPI than the distance to the Metropolitan area or coastal departmental capitals. Finally, we find evidence of spatial externalities of MPI across districts which also seem to be stronger than the direct effect of altitude and distance. [ABSTRACT FROM AUTHOR]

The increasing number of claims filed by Indigenous peoples against pollution caused by extractive industries makes the challenge of factualizing and measuring the damage caused in their territories necessary. In Peru, the Kukama Kukamiria people are among the most affected by the various spills from the North Peruvian Pipeline since its construction, one of the most well-known occurred in the lower Marañón River in 2014. This paper is about the efforts and limitations involved in aligning the Kukama Kukamiria's experiences with the criteria and frameworks for measuring damage and compensation amid the toxic environment and the complicated time and space of late capitalism. Based on ethnographic research and considering the judicial processes, the analysis found that compensation became a tool of dispute in which incommensurable Indigenous worlds emerged to claim for their incommensurability to exist. But in the Peruvian neoliberal and extractive context, compensation also became a technique for governing Indigenous lives and natures in a way that excludes those worlds. [ABSTRACT FROM AUTHOR]

Background: Probiotics in allergic rhinitis (AR) have shown improvement in clinical and quality of life scores, whereas the role of synbiotics in the treatment of AR has been poorly investigated. The purpose of this study was to evaluate the clinical efficacy of synbiotics in children with AR. Methods: An observational, prospective cohort study of pediatric outpatients with AR from a private medical center in Peru (2021) was conducted. At baseline, patients who were prescribed synbiotics during routine and those who were not (controls) recruited and followed up on Days 30, 60, and 90 of follow‐up. Clinical efficacy was assessed with differences in Visual Analogous Scale (VAS), Total Nasal Symptom Score (TNSS), Rhinitis Control Assessment Test (RCAT), and the Pediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ) scores between groups at follow‐up. Mean differences ± standard deviation (SD) and 95% confidence intervals (95% CI) are reported. Results: Two hundred and fifteen participants were analyzed. Compared to controls (n = 115), those who used synbiotics (n = 100) had significantly lower VAS (mean difference 1.3; 95% CI: 0.8–1.8), TNSS (mean difference 1.1; 95% CI: 0.5–1.7) and higher RCAT scores and PRQLQ scores (mean difference 2.2; 95% CI: −3.3 to −1.2) and (mean difference 7.0; 95% CI: 3.1–10.9), respectively, at Day 90 of follow‐up Conclusions: This paper reports significant improvement in clinical (VAS, RCAT, TNSS) and quality of life (PRQLQ) scores of small and large sizes, respectively. These preliminary findings support the need of future trials to assess the role of synbiotics in children with AR. [ABSTRACT FROM AUTHOR]

In 30 years of commercial relations between Colombia and Peru within the framework of their different integration processes, this article aimed to analyze the Colombian companies that boost bilateral trade with Peru. The study reveals the companies and the main goods traded, the study was developed from the theoretical perspective of economic integration and the concept of South-South trade, through a predominantly quantitative method, with 300,692 data obtained from the interface of the National Statistical System (SEN) fed by the Tax and Customs Directorate Nationals (DIAN) during the last 5 years, 24,651 export operations and 18,305 import operations were obtained. Within the findings, the Colombian companies that export the most, those that import the most, and those with the highest volume of trade are categorized. The industry with the highest business participation is the hygiene and personal care sector, which ranks 5 companies out of the 10 with the highest commercial volume with significant exchanges in essential oils, chemical preparations, plastic, and paper manufactures. Regarding their size, it was found that 100% They are large multinational companies, with more than 50 years in the market. Of the 10 most representative companies: 2 are Colombian, 2 Peruvian, 4 American and 2 European. [ABSTRACT FROM AUTHOR]

The complex and colorful textiles of ancient Peru have long been a focus of technical study, particularly to characterize the sources of the wide variety of dyes utilized by these Andean artisans. This manuscript describes the characterization of the dyes of both primary (red, blue, and yellow) and secondary (purple, orange, and green) colors sampled from textiles spanning five major civilizations: the Paracas Necropolis, the Nazca, the Wari, the Chancay, and the Lambayeque, all from Peru. All but the Paracas Necropolis samples were part of technical conservation studies of the ancient South American textiles collections of the Michael C. Carlos Museum. Analysis of the dyes was carried out utilizing direct analysis in real time time-of-flight mass spectrometry (DART-MS) and paper spray MS. To validate these ambient ionization MS methods, the samples were further investigated using high-performance liquid chromatography (HPLC) with ultraviolet-visible diode array detection (DAD). These results show that ambient ionization MS methods are simple and fast for characterization of the general classes of dyes, e.g., plant reds vs. insect reds, and indigoids in blues and greens. Due to the myriad possible sources of yellow dyes and their tendency to undergo oxidative decomposition, positively identifying those components in these yarns was difficult, though some marker compounds and flavonoid decomposition products were readily identified by ambient ionization mass spectrometry.

TikTok's infotainment exposes users to disturbing and harmful content, mainly broadcast by conservative groups. In this paper, we analyze the political uses from conservative groups during the social polarization in Peru in 2022. Fake news, harassing messages and promoting violence go unnoticed due to the application's lax security of the app. From a qualitative perspective of an exploratory study, we studied videos and comments on TikTok from conservative groups, regarding only the ones with inappropriate content that is still available and violates TikTok's policies. Findings show that these groups produce discourses that assume protective positions from moral privileges that represent current fears in hypothetical futures (temporarydystopian), build their communication from the perspective of the forgotten man or the deprivation of privileges (actor-victimizer) and isolate demands from political to an individual (sacralized-spatial) perspective. We have categorized our findings as follows: a) unsatisfaction, b) deprivation, c) relegation and d) oblivion. This article seeks to contribute to the initial research on the politicalcommunicative uses of TikTok. [ABSTRACT FROM AUTHOR]

With the spread of SARS-CoV-2, all universities were forced to implement the virtual modality in their curricula so as not to paralyze the educational system. Likewise, the Universidad Nacional Mayor de San Marcos, located in the city of Lima, Peru, continued with non-face-toface classes through virtual resources to help its students in the learning process. Therefore, this research aimed to determine the factors of the student role that influenced the satisfaction of managing virtual resources. The study procedure included the collection of 184 surveys through Google Forms and the analysis of validity, structural model, reliability and hypothesis tests using the non-parametric Spearman's Rho test. Some of the limitations of the analysis were due to generational differences and socioeconomic and geographic variables of the participants. This paper found, according to the order of the highest score of the correlation coefficient, that the factors student-content interaction, gamified participation, motivation, self-efficacy in internet and computing, and perceived usefulness predicted the satisfaction of managing virtual resources in students. It was concluded that the five independent variables were significantly correlated in the dependent variable. [ABSTRACT FROM AUTHOR]

Objective/context: In the early twentieth century, Peru rejected legal pluralism and, once again, selected a highly European-inflected penal code, undergirded by the prevailing tenets of legal positivism. In doing so, criminal courts became a particularly contested site, where indigenous and mestizas (mixed-race) women shaped and negotiated racial sentiments constructed around their sexuality. In also shaping the meaning of the law itself, I contend that virginity—or lack thereof—patterned legal positivism in Peru. I first detail the historical impact of legal positivism on Peru’s judiciary. I then showcase women’s courtroom narratives (alongside other juridical testimonies) that reveal their struggle for political inclusion. Methodology: This article is built from an analysis of primary and original archival data and is the synthesis of 55 cases of alleged sexual transgressions occurring in the region of Cuzco from 1924 to 1949. Originality: This paper is significant because it is one of only a few that examine the history of legal positivism and rape prosecution in the early twentieth century by incorporating primary archival data to show how women were protagonists in shaping Peru’s unique legal, political and cultural history. Conclusions: Expanding the arguments of imminent Andean scholars of postcolonialism, I argue that the ‘coloniality of law’ in Peru is illuminated by the collusion of legal positivism and fin de siècle racial ideologies that created a new subjectivity for women. In addition to refashioning repressive honor codes (literally embodied in ideas about morality and chastity), the new penal code also broadened a gap where indigenous and mestizo women argued their juridical humanity in criminal courts.

The pork tapeworm, Taenia solium, is the cause of a preventable zoonotic disease, cysticercosis, affecting both pigs and humans. Continued endemic transmission of T. solium is a major contributor of epilepsy and other neurologic morbidity, and the source of important economic losses, in many rural areas of developing countries. Simulation modelling can play an important role in aiding the design and evaluation of strategies to control or even eliminate transmission of the parasite. In this paper, we present a new agent based model of local-scale T. solium transmission and a new, non-local, approach to the model calibration to fit model outputs to observed human taeniasis and pig cysticercosis prevalence simultaneously for several endemic villages. The model fully describes all relevant aspects of T. solium transmission, including the processes of pig and human infection, the spatial distribution of human and pig populations, the production of pork for human consumption, and the movement of humans and pigs in and out in several endemic villages of the northwest of Peru. Despite the high level of uncertainty associated with the empirical measurements of epidemiological data associated with T. solium, the non-local calibrated model parametrization reproduces the observed prevalences with an acceptable precision. It does so not only for the villages used to calibrate the model, but also for villages not included in the calibration process. This important finding demonstrates that the model, including its calibrated parametrization, can be successfully transferred within an endemic region. This will enable future studies to inform the design and optimization of T. solium control interventions in villages where the calibration may be prevented by the limited amount of empirical data, expanding the possible applications to a wider range of settings compared to previous models.

The construction technique of raw earth, which has always been in use in most of the world, has left large monuments or architectural complexes to cultural heritage that need special attention due to the notable vulnerability of the material. A convenient way to deal this threat, besides physical intervention, is by using an information system, such as HBIM (Heritage Building Information Modeling), as a tool for damage assessment and conservation planning. This paper reports on its application in an archaeological setting, in particular, on the Huaca Arco Iris, a religious building of the old city of Chan Chan (Peru), the largest monumental complex in mud on the American continent. The study is part of the bilateral international project between the Consiglio Nazionale delle Ricerche (CNR) and the Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica (CONCYTEC) in the use of HBIM for the prediction of possible natural or anthropogenic damages to buildings in raw mud. Exploiting the data coming from the direct and indirect analyses, a dedicated ontology is built to guide the management of these data within the information system. The creation of an HBIM system for the archaeological domain, based on the trinomial data–information–knowledge, is presented and validated. Following this approach, a customizable HBIM has been created with the 3D model of the spatial entities of the Huaca. As a result, the semantic relationship of an external wall, taken as the benchmark test of our experiment, with the contained bas-relief and the conservation cover is tested. [ABSTRACT FROM AUTHOR]

Aim: To evaluate disparities in the frequency of scientific activity between medical doctors and nurses in Peru. Methods: We carried out a secondary data analysis of the National Health Services Users' Satisfaction Survey (ENSUSALUD), 2016. This nationally representative survey evaluates doctors and nurses working in clinical settings. We defined scientific activity as i) having published an original article (journal indexed in Web of Science, Scopus or Medline); and ii) having authored an abstract in a national or international conference. We estimated crude and adjusted disparities prevalence ratios (aDPR) and 95% confidence intervals (95%CI). Results: We included 2025 doctors and 2877 nurses in the analysis; 71% of doctors doctor were male, and 93% of nurses were female (p<0.001). Among doctors, 13.9% had published an article, and 8.4% presented an abstract at a conference in the last two years, while these proportions were 0.6% and 2.5% for nurses, respectively. The adjusted models showed that doctors, when compared to nurses, were approximately 27 times likely to have published a paper (aDPR = 27.86; 95% CI 10.46 to 74.19) and twice as likely to have authored a conference abstract (aDPR = 2.51; 95% CI 1.39 to 4.53). Conclusions: There are important disparities in scientific activity between doctors and nurses working in clinical settings in Peru. Disparities are more significant for article publication than for authoring in conference abstracts. We suggest public policies that promote research dissemination between health professionals, with emphasis on nurses. [ABSTRACT FROM AUTHOR]
