Cardiovascular Disease in Patients with Chronic Obstructive Pulmonary Disease, Obstructive Sleep Apnoea Syndrome and Overlap Syndrome
Authors: Voulgaris A. , Archontogeorgis K. , Steiropoulos P. , Papanas N.
Published: March 2020

Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnoea syndrome
(OSAS) are among the most prevalent chronic respiratory disorders. Accumulating data suggest that
there is a significant burden of cardiovascular disease (CVD) in patients with COPD and OSAS, affecting
negatively patients’ quality of life and survival. Overlap syndrome (OS), i.e. the co-existence of
both COPD and OSAS in the same patient, has an additional impact on the cardiovascular system multiplying
the risk of morbidity and mortality. The underlying mechanisms for the development of CVD in
patients with either OSAS or COPD and OS are not entirely elucidated. Several mechanisms, in addition
to smoking and obesity, may be implicated, including systemic inflammation, increased sympathetic
activity, oxidative stress and endothelial dysfunction. Early diagnosis and proper management of these
patients might reduce cardiovascular risk and improve patients' survival. In this review, we summarize
the current knowledge regarding epidemiological aspects, pathophysiological mechanisms and present
point-to-point specific associations between COPD, OSAS, OS and components of CVD, namely, pulmonary
hypertension, coronary artery disease, peripheral arterial disease and stroke.

Authors: Patoulias Dimitrios , Stavropoulos Konstantinos , Imprialos Konstantinos , Athyros Vasilios , Grassos Haris , Doumas Michael , Faselis Charles
Published: March 2020

Background:

Cardiovascular disease (CVD) still remains the leading cause of morbidity and
mortality worldwide. It is now established that inflammation plays a crucial role in atherosclerosis and
atherothrombosis, and thus, it is closely linked to cardiovascular disease.

Objective:

The aim of the present review is to summarize and critically appraise the most relevant evidence
regarding the potential use of inflammatory markers in the field of CVD.

Method:

We conducted a comprehensive research of the relevant literature, searching MEDLINE from
its inception until November 2018, primarily for meta-analyses, randomized controlled trials and observational
studies.

Results:

Established markers of inflammation, mainly C-reactive protein, have yielded significant results
both for primary and secondary prevention of CVD. Newer markers, such as lipoprotein-associated
phospholipase A2, lectin-like oxidized low-density lipoprotein receptor-1, cytokines, myeloperoxidase,
cell adhesion molecules, matrix metalloproteinases, and the CD40/CD40 ligand system, have been
largely evaluated in human studies, enrolling both individuals from the general population and patients
with established CVD. Some markers have yielded conflicting results; however, others are now recognized
not only as promising biomarkers of CVD, but also as potential therapeutic targets, establishing
the role of anti-inflammatory and pleiotropic drugs in CVD.

Conclusion:

There is significant evidence regarding the role of consolidated and novel inflammatory
markers in the field of diagnosis and prognosis of CVD. However, multimarker model assessment, validation
of cut-off values and cost-effectiveness analyses are required in order for those markers to be
integrated into daily clinical practice.
A Tropical Lichen, Dirinaria consimilis Selectively Induces Apoptosis in MCF-7 Cells through the Regulation of p53 and Caspase-Cascade Pathway
Authors: Shendge Anil K. , Panja Sourav , Basu Tapasree , Mandal Nripendranath
Published: March 2020

Background:

Breast cancer is the most leading cause of death, with 49.9% of crude incidence rate
and 12.9% of crude mortality rate. Natural resources have been extensively used throughout history for better
and safer treatment against various diseases.

Objectives:

The present study was aimed to investigate the antioxidant and anticancer potential of a tropical
lichen Dirinaria consimilis (DCME) and its phytochemical analysis.

Methods:

The DCME was preliminarily evaluated for ROS, and RNS scavenging potential. Furthermore,
DCME was evaluated for in vitro anticancer activity through cell proliferation assay, cell cycle analysis, annexin
V/PI staining, morphological analysis, and western blotting study. Finally, the HPLC and LC-MS analyses were
done to identify probable bioactive compounds.

Results:

The in vitro antioxidant studies showed promising ROS, and RNS scavenging potential of DCME.
Moreover, the in vitro antiproliferative study bared the cytotoxic nature of DCME towards MCF-7 (IC50 - 98.58
± 6.82μg/mL) and non-toxic towards WI-38 (IC50 - 685.85 ± 19.51μg/mL). Furthermore, the flow-cytometric
analysis revealed the increase in sub G1 population as well as early apoptotic populations dose-dependently. The
results from confocal microscopy showed the DNA fragmentation in MCF-7 upon DCME treatment. Finally, the
western blotting study revealed the induction of tumor suppressor protein, p53, which results in increasing the
Bax/Bcl-2 ratio and activation of caspase-cascade pathways.

Conclusion:

The activation of caspase-3, -8, -9 and PARP degradation led us to conclude that DCME induces
apoptosis in MCF-7 through both intrinsic and extrinsic mechanisms. The LC-MS analysis showed the presence
of various bioactive compounds.
Activation of Intrinsic Apoptosis and G1 Cell Cycle Arrest by a Triazole Precursor, N-(4-chlorophenyl)-2-(4-(3,4,5-trimethoxybenzyloxy)benzoyl)-hydrazinecarbothioamide in Breast Cancer Cell Line
Authors: Arulnathan Stephanie B. , Leong Kok H. , Ariffin Azhar , Kareem Huda S. , Cheah Kevin K.H.
Published: March 2020

Background:

Oxadiazoles, triazoles, and their respective precursors have been shown to exhibit various
pharmacological properties, namely antitumour activities. Cytotoxic activity was reported for these compounds in
various cancer cell lines.

Aim and Objectives:

In this study, we aim at investigating the mechanism of apoptosis by N-(4-chlorophenyl)-2-(4-
(3,4,5-trimethoxybenzyloxy)benzoyl)-hydrazinecarbothioamide, a triazole precursor, henceforth termed compound
P7a, in breast cancer cell line, MCF-7. We first screen a series of analogues containing (3,4,5-trimethoxybenzyloxy)
phenyl moiety in breast cancer cell lines (MCF-7 and MDA-MB-231) to select the most cytotoxic compound and
demonstrate a dose- and time-dependent cytotoxicity. Then, we unravel the mechanism of apoptosis of P7a in MCF-7 as
well as its ability to cause cell cycle arrest.

Methods:

Synthesis was performed as previously described by Kareem and co-workers. Cytotoxicity of analogues
containing (3,4,5-trimethoxybenzyloxy)phenyl moiety against MCF-7 and MDA-MB-231 cell lines was evaluated
using the MTS assay. Flow cytometric analyses was done using Annexin V/PI staining, JC-1 staining and ROS
assay. The activity of caspases using a chemoluminescence assay and western blot analysis was conducted to study
the apoptotic pathway induced by the compound in MCF-7 cells. Lastly, cell cycle analysis was conducted using
flow cytometry.

Results:

Upon 48 hours of treatment, compound P7a inhibited the proliferation of human breast cancer cells with
IC50 values of 178.92 ± 12.51μM and 33.75 ± 1.20μM for MDA-MB-231 and MCF-7, respectively. Additionally,
compound P7a showed selectivity towards the cancer cell line, MCF-7 compared to the normal breast cell line,
hTERT-HME1, an advantage against current anticancer drugs (tamoxifen and vinblastine). Flow cytometric analyses
using different assays indicated that compound P7a significantly increased the proportion of apoptotic cells,
increased mitochondria membrane permeabilisation and caused generation of ROS in MCF-7. In addition, cell cycle
analysis showed that cell proliferation was arrested at the G1 phase in the MCF-7 cell line. Furthermore, upon
treatment, the MCF-7 cell line showed increased activity of caspase-3/7, and caspase-9. Lastly, the western blot
analysis showed the up-regulation of pro-apoptotic proteins along with up-regulation of caspase-7 and caspase-9,
indicating that an intrinsic pathway of apoptosis was induced.

Conclusion:

The results suggest that compound P7a could be a potential chemotherapeutic agent for breast cancer.
The Frequency of the Intestinal Parasites Giardia Lamblia and Entamoeba Histolytica in Pediatric Diarrhea Specimens from Central Iran
Authors: Abbasi Elnaz , Amouzandeh-Nobaveh Alireza , Ghaznavi-Rad Ehsanollah
Published: March 2020

Introduction:

Intestinal parasitic infections, particularly those caused by Giardia lamblia, are among the major health problems that exist worldwide, especially in developing countries. This study aimed to investigate the prevalence of the intestinal parasites Giardia lamblia and Entamoeba histolytica that were isolated from samples of infectious diarrhea in pediatric patients from Central Iran.

Methods:

This descriptive cross-sectional study included 230 samples of infectious diarrhea that were collected from May 2015 to February 2016. Direct observation, the formalin-ether sedimentation method and the technique using the Polymerase Chain Reaction (PCR) of β-giardin and EH primers were used for the identification of Giardia lamblia and Entamoeba histolytica.

Results:

Out of 230 samples of infectious diarrhea, five cases (2.1%) of Giardia lamblia and no cases (0%) of Entamoeba histolytica were identified using the formalin-ether sedimentation method and the same result were obtained using PCR technique. Of the five patients who had Giardia lamblia, three (60%) were male and two (40%) were female. The most common clinical symptoms in these patients were stomach ache and diarrhea (100%) and mucus in the stool (80%).

Conclusion:

Giardia lamblia was introduced as a parasitic agent causing diarrhea from Central Iran. The results indicate that pediatricians and, even more importantly, experts in laboratories should pay special attention to the identification of this parasite to treat the patients as effectively and as quickly as possible.
The Current State of Research, Challenges, and Future Research Directions of Blockchain Technology in Patient Care: Systematic Review (Preprint)
Authors: Durneva Polina , Cousins Karlene , Chen Min
Published: March 2020

BACKGROUND

Blockchain offers a promising new distributed technology to address the challenges of data standardization, system interoperability, security, privacy, and accessibility of medical records.

OBJECTIVE

The purpose of this review is to assess the research on the use of blockchain technology for patient care and the associated challenges and to provide a research agenda for future research.

METHODS

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. We queried the Cumulative Index of Nursing and Allied Health Literature (CINAHL), PubMed, Excerpta Medica dataBASE (EMBASE), and Web of Science databases for peer-reviewed research articles published up to December 2019 that examined the implementation of blockchain technology in health care settings. We identified 800 articles from which we selected 70 empirical research articles for a detailed review.

RESULTS

Blockchain-based patient care applications include medical information systems, personal health records, mobile health and telemedicine, data preservation systems and social networks, health information exchanges and remote monitoring systems, and medical research systems. These blockchain-based health care applications may improve patient engagement and empowerment, improve health care provider access to information, and enhance the use of health care information for medical research.

CONCLUSIONS

Blockchain health information technology (HIT) provides benefits such as ensuring data privacy and security of health data, facilitating interoperability of heterogeneous HIT systems, and improving the quality of health care outcomes. However, barriers to using blockchain technology to build HIT include security and privacy vulnerabilities, user resistance, high computing power requirements and implementation costs, inefficient consensus algorithms, and challenges of integrating blockchain with existing HIT. With 51% of the research focused on medical information systems such as electronic health record and electronic medical record, and 53% of the research focused on data security and privacy issues, this review shows that HIT research is primarily focused on the use of blockchain technologies to address the current challenges HIT faces. Although Blockchain presents significant potential for disrupting health care, most ideas are in their infancy.

Magnetic resonance imaging findings and its association to electroencephalogram in children with partial epilepsy (Preprint)
Authors: Quang Huy Huynh
Published: March 2020

BACKGROUND

It is important to identify the neuroimaging features that are associated with partial epilepsy in preschool children. Advances in technology recently to localize focal epileptogenic lesions, especially that of high-resolution structural imaging with magnetic resonance imaging (MRI). The recommendation that electroencephalography (EEG) should be gold criteria and that M.R.I should be optional has been questioned.

OBJECTIVE

The present study aims to to explore the brain lesions on MRI and its association to electroencephalogram in children with partial epilepsy.

METHODS

The present study was conducted among 112 preschool children with history of partial seizures. All patients underwent EEG and brain MRI. The epileptogenic lesions were identified on the basis of the signal intensities and morphological abnormalities seen on MRI. The correlation between MRI and EEG abnormalities was explored using a chi-square test.

RESULTS

Abnormal MRI were found in 34.8% (n = 39) of the sample. The EEG and MRI agreed with respect to classify into abnormal or normal in 48.2% (n = 54). Of the 27 patients with a normal EEG, six (22.2%) were seen to have an abnormal MRI.

CONCLUSIONS

A number of MRI abnormalities was found in our study of otherwise
normal children, although the correlation between these results was not clear. Follow-up of these children will help us identify the important abnormalities. Despite of small sample, our results showed that a normal E.E.G findings does not predict a normal brain MRI in children with partial epilepsy.
Characteristics of Hospital Acquired Pressure Injury and Factors Affecting Its Development: A Retrospective Study (Preprint)
Authors: Mortada Hatan , Malatani Nader , Awan Basim , Aljaaly Hattan
Published: March 2020

BACKGROUND

Across the globe, Pressure Injury (PI) has been implicated billion costs annually and mortality were 60,000 deaths out of 2.5 million hospitalized patients from complication related to PI. Through avoiding PI will avoid the incidence of other illnesses, decrease the financial costs and improve the quality of life for our patients.

OBJECTIVE

Therefore, this retrospective study aimed to identify most influential factors which increase the risk of developing pressure injuries among hospitalized patients at a university hospital according to the Waterlow scale.

METHODS

Data were collected retrospectivity including patients who developed pressure injury during January 2016 to December 2018 were evaluated using Waterlow pressure injury risk assessment tool at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia. The analysis was performed in 95% confidence interval using the Statistical Package for Social Science (SPSS), version 23.0 (IBM, Armonk, NY, USA). Ethical approval was obtained from the Institutional Review Board and the Research Ethics Committee.

RESULTS

Total 272 cases were included in this study. Highest number of cases belong to age group 50 to 64 years, 83 (30.5%). The majority had stage 2 pressure ulcer, 165 (60.7%). The most frequent location of pressure ulcer was ‘back’, 97 (35.7%). History of undergoing major surgery was statistically significantly associated with higher stage of pressure ulcer (p-value .040). The mean Waterlow pressure injury score for all cases was 27.19 ± 13.143. There is a moderate uphill correlation between neurological deficit score and Waterlow PI score was observed, (Correlation coefficient: .447, p. <.001). Multinomial logistic regression analysis revealed increasing age is a significant predictive factor for developing higher stages of pressure ulcer (p .046).

CONCLUSIONS

This study indicated that major surgery, neurological deficit, low hemoglobin, and increasing age are strong predictors for developing higher stages of pressure injury. Therefore, health care contributors should consider these risks when applying a comprehensive pressure injury management plan.
Explainable Artificial Intelligence Recommendation System by Leveraging the Semantics of Adverse Childhood Experiences: Proof-of-Concept Prototype Development (Preprint)
Authors: Ammar Nariman , Shaban-Nejad Arash
Published: March 2020

BACKGROUND

The study of adverse childhood experiences and their consequences has emerged over the past 20 years. Although the conclusions from these studies are available, the same is not true of the data. Accordingly, it is a complex problem to build a training set and develop machine-learning models from these studies. Classic machine learning and artificial intelligence techniques cannot provide a full scientific understanding of the inner workings of the underlying models. This raises credibility issues due to the lack of transparency and generalizability. Explainable artificial intelligence is an emerging approach for promoting credibility, accountability, and trust in mission-critical areas such as medicine by combining machine-learning approaches with explanatory techniques that explicitly show what the decision criteria are and why (or how) they have been established. Hence, thinking about how machine learning could benefit from knowledge graphs that combine “common sense” knowledge as well as semantic reasoning and causality models is a potential solution to this problem.

OBJECTIVE

In this study, we aimed to leverage explainable artificial intelligence, and propose a proof-of-concept prototype for a knowledge-driven evidence-based recommendation system to improve mental health surveillance.

METHODS

We used concepts from an ontology that we have developed to build and train a question-answering agent using the Google DialogFlow engine. In addition to the question-answering agent, the initial prototype includes knowledge graph generation and recommendation components that leverage third-party graph technology.

RESULTS

To showcase the framework functionalities, we here present a prototype design and demonstrate the main features through four use case scenarios motivated by an initiative currently implemented at a children’s hospital in Memphis, Tennessee. Ongoing development of the prototype requires implementing an optimization algorithm of the recommendations, incorporating a privacy layer through a personal health library, and conducting a clinical trial to assess both usability and usefulness of the implementation.

CONCLUSIONS

This semantic-driven explainable artificial intelligence prototype can enhance health care practitioners’ ability to provide explanations for the decisions they make.
Measuring Adoption of Patient Priorities–Aligned Care Using Natural Language Processing of Electronic Health Records: Development and Validation of the Model (Preprint)
Authors: Razjouyan Javad , Freytag Jennifer , Dindo Lilian , Kiefer Lea , Odom Edward , Halaszynski Jaime , Silva Jennifer W , Naik Aanand D
Published: March 2020

BACKGROUND

Patient Priorities Care (PPC) is a model of care that aligns health care recommendations with priorities of older adults who have multiple chronic conditions. Following identification of patient priorities, this information is documented in the patient’s electronic health record (EHR).

OBJECTIVE

Our goal is to develop and validate a natural language processing (NLP) model that reliably documents when clinicians identify patient priorities (ie, values, outcome goals, and care preferences) within the EHR as a measure of PPC adoption.

METHODS

This is a retrospective analysis of unstructured National Veteran Health Administration EHR free-text notes using an NLP model. The data were sourced from 778 patient notes of 658 patients from encounters with 144 social workers in the primary care setting. Each patient’s free-text clinical note was reviewed by 2 independent reviewers for the presence of PPC language such as priorities, values, and goals. We developed an NLP model that utilized statistical machine learning approaches. The performance of the NLP model in training and validation with 10-fold cross-validation is reported via accuracy, recall, and precision in comparison to the chart review.

RESULTS

Of 778 notes, 589 (75.7%) were identified as containing PPC language (kappa=0.82, P<.001). The NLP model in the training stage had an accuracy of 0.98 (95% CI 0.98-0.99), a recall of 0.98 (95% CI 0.98-0.99), and precision of 0.98 (95% CI 0.97-1.00). The NLP model in the validation stage had an accuracy of 0.92 (95% CI 0.90-0.94), recall of 0.84 (95% CI 0.79-0.89), and precision of 0.84 (95% CI 0.77-0.91). In contrast, an approach using simple search terms for PPC only had a precision of 0.757.

CONCLUSIONS

An automated NLP model can reliably measure with high precision, recall, and accuracy when clinicians document patient priorities as a key step in the adoption of PPC.
A Primer on Congenital Anomalies of the Kidneys and Urinary Tracts (CAKUT)
Authors: Murugapoopathy Vasikar , Gupta Indra R.
Published: March 2020

Congenital anomalies of the kidneys and urinary tracts (CAKUT) are disorders caused by defects in the development of the kidneys and their outflow tracts. The formation of the kidneys begins at week 3 and nephrogenesis continues until week 36, therefore, the kidneys and outflow tracts are susceptible to environmental risk factors that perturb development throughout gestation. Many genes have been implicated in kidney and outflow tract development, and mutations have been identified in patients with CAKUT. In severe cases of CAKUT, when the kidneys do not form, the fetus will not survive. However, in less severe cases, the baby can survive with combined kidney and outflow tract defects or they may only be identified in adulthood. In this review, we will cover the clinical presentation of CAKUT, its epidemiology, and its long-term outcomes. We will then discuss risk factors for CAKUT, including genetic and environmental contributions. Although severe CAKUT is rare, low nephron number is a much more common disorder with its effect on kidney function increasingly apparent as a person ages. Low nephron number appears to arise by the same mechanisms as CAKUT, but it differs in terms of the magnitude of the insult and the timing of when it occurs during gestation. By understanding the causes of CAKUT and low nephron number, we can begin to identify preventive treatments and establish clinical guidelines for how these patients should be followed.

Excluding the Middle

Published: March 2020

En este artículo muestro cómo varias amenazas de la ley clásica del Tercero Excluido pueden atacarse mediante el cálculo-ϵ de Hilbert y la noción de elección que comprende. Tras introducir informalmente este cálculo, expongo su utilidad en la teoría de la referencia ya que necesita tener términos que denoten, mismos que no necesariamente describen lo que denotan. Así, es posible, dentro del cálculo-ϵ de Hilbert, que ‘FϵxFx’ sea falso (puesto que es exactamente equivalente a ‘(Ex)Fx’) y, por consiguiente, ‘ϵxFx’ denote un objeto al que ‘F’ puede no describir. Ésta es una teoría no-clásica de las descripciones, pero nos proporciona inmediatamente una teoría de las ficciones dentro de la lógica clásica: ya que, al tomar ‘ϵxFx’ como ‘la F’, podemos decir invariablemente GϵxFx˅-GϵxFx, exista o no una F. Es así como la ley del Tercero Excluido se salva aquí, y un argumento similar salva aquí, y un argumento similar salva a la ley en el caso de contingencias futuras y circunstancias pasadas contrafácticas. Además, el principio según el cual GϵxFx es verdadero o falso por elección cuando FϵxFx indica defensas ‘electivas’ similares de la ley con respecto a errores categoriales y de vaguedad. El artículo finaliza con un análisis más detallado del caso contrafáctico abordando directamente la cuestión del ‘Tercero Excluido Condicional’.

Teoría general de las decisiones
Authors: García de la Sienra Adolfo
Published: March 2020

Starting from Simon's (1976) opposition between procedural and substantive rationality, the paper addresses the question whether it is possible to characterize the former in general terms, and discusses the problem of overcoming the aforementioned opposition. It tries to show, by means of the concept of a general decision structure, that even though it is not possible to characterize procedural rationality in an exhaustive and fully general way, at least it is possible to introduce a scheme within which it is possible to pose problems of procedural rationality, or even to postulate sorne axiomatic restrictions for the same, It is not hard to see that substantive rationality is a particular case of this scheme, namely, the case in which it is possible to measure certain theoretical parameters and adopt as rules of decision certain classical principIes grounded upon the concept of expected utility. The paper does not provide, however, the details that show how the special theory is obtained out of the more general one. [A. G. S.]

Resumen
Berkeley y Benacerraf la aritmética es sólo un sistema de signos
Authors: Robles José Antonio
Published: March 2020

In this paper I point out that besides having made a proposal -with respect to arithmetic (and algebra)- which makes Berkeley an antecesor of Hartry Field -something which I do not elaborate more in this paper-, he also puts forth a nominalistic view which, in substantial points, is closely related to Benacerraf's in his "What Numbers Could Not Be". What I hold is that Berkeley's view, two hundred years before Benacerraf's, fullfils the latter's claim for numerical expressions to be meaningful and to make them useful in human practices. I interpret sorne proposals by Berkeley which would ground the construction of a mathematical structure in which no use is made of sets or any type of entities -besides the structure itself, of which I give an example-, to give meaning to the expressions which constitute it. Such expressions get their meaning from the proposition they have in the said structure. I take it that a nominalistic position, at least at the level of elementary mathematics, avoids many theoretical problems which arise if we adopt a less econornical ontological position.

Realismo epistemológico, referencia y verosimilitud
Authors: Cassini Alejandro
Published: March 2020

This paper attempts to determine the commitements of the realist view of scientific theories. First, it distinguishes between ontological realism and epistemological realismo Then, it affirms that the latter is committed with the concepts of reference and truthlikeness. It rejects the so-called referential realism, and against this, it maintains that it is not possible to perform genuine acts of reference by means of false descriptions, Every act of reference needs a true description, It exemplifies this thesis with the problem of identifying elementary particles. Finally, it concludes by analysing the condítions which are necessary and sufficient for the conservation of the reference when a change of theory takes place.
Un sistema lógico de segundo orden conceptualista con operadores lambda ramificados
Authors: Freund Max A.
Published: March 2020

We develop a second order logical system with ramified lambda operators, having ramified conceptualism as its philosophical background. Such a system is shown to relatively consistent. Finally, we construct a non-standard second order semantics and prove a completeness theorem with respect to a uotion oí validity, provided by the semantics, and certain extensions oí the second order system.
Cummins and Conditionals
Authors: Duran Jane
Published: March 2020

En este artículo el trabajo de Cummins y colaboradores sobre los condicionales se analiza y critica desde dos perspectivas: la primera señala la insuficiente atención que se presta al empleo del condicional material en un contexto causal, y la segunda indica el grado en que la investigación lleva a cabo afirmaciones e implicaciones para establecer modelos de cognición no basados en reglas, tales como el de Johnson-Laird. Se cita a Bereiter y se hace referencia al trabajo de Braine y O’Brien. Como conclusión se postula que gran parte de las investigaciones sobre razonamiento de condicionales aún no toma en cuenta lo suficiente las extravagancias del lenguaje natural.

Sistemas de cálculo como formas de Logicismo
Authors: Fernández Ángel Nepomuceno
Published: March 2020

The logicism may be regarded like a fossil stone that has not utility nowadays. In this sense, logicism took care of the research about the foundations of mathematics but apparently its task arrived at its end many years ago because of sorne results that were eetablished during the century. However it is not wholly right. Understanding logicism as an attempt to reduce classical mathematics to logic means we can distinguish: 1) the idea according to which mathematic is logic in sorne way, and 2) a metaphysical program of research to: a) define mathematical notions as logical notions, and b) show that the mathematical theorems are logical theorems. The failure (if so) concerned to 2), since 1) was assumed by many logicians. Recovering logicism is not easy and there may be several ways. One of them is the one followed by N.B. Cocchiarella whose systems (there are more than one) represent a form of logicism (Frege's or Russell's form). From those systems -though a bit changed from my own point of view- we can define a modal calcule that may have application in computer science, what would not be a stale work. From a common language we take in account two systems in order to show that Cocchiarella's modified system is as powerful deductively as that of Church modified functional second order calcule. We can obtain new systems that represent form of logicism and are more powerful than that of Church enlarging Cochiarella's modified system. These new systems, that becomes modal systems provided that one adds appropiate modal tools (then they may be used in computer science), may be useful to study logicism itself (as historical philosophy of logic and mathematics).

Resumen
El gene como factor causal probabilístico en la teoría de la selección natural
Authors: López Beltrán Carlos
Published: March 2020

This paper aims to give a causal account of the privileged status of genes in the theory of natural selection. Adding to the arguments that Dawkins (1976, 1982) and Kitcher & Sterelny (1989) have given for a distinction between the role of genes as units of natural selection, and that of other structures and properties from higher levels of organization, it criticizes the hierarchical view of a multiplicity of units for its lack of awareness of a basic causal assymetry between the genic and other levels. Being located at what one might call a Weismannian vertex, genes, it is argued, neatly articulate the two different dimensions of probabilistic causality, the token causality and the type causality. They do not have the passive (book-keeping) role some authors want to give them but are causally (probabilistically) responsible both for the recurrence of features from generation to generation, and for the presence of similar genes in future gene-pools. Heritability, it is also argued, when properly understood, can be seen as the biological property that captures this dual causal role of genes.
Modelos alternativos de financiamiento para las bibliotecas públicas de México
Authors: Hernández Pacheco Federico
Published: March 2020

El presupuesto otorgado por el gobierno mexicano para sus bibliotecas públicas actualmente es mínimo, y es por ello que se buscan fuentes alternativas de ingresos para fnanciar proyectos de diversa índole dentro de esta importante institución pública. Muchas bibliotecas alrededor del mundo, pero especialmente en Estados Unidos y España, han implementado el fundraising en sus bibliotecas públicas consiguiendo muy buenos resultados. En la presente investigación se pretenden dar a conocer datos relevantes del presupuesto público otorgado para bibliotecas públicas en México, así como propuestas y esquemas que ayuden a desarrollar planes y programas para captar recursos externos y de diversas fuentes, además de presentar casos de éxito reales.
El acceso a la información pública en casos de graves violaciones a los derechos humanos en México
Authors: Pelayo Moller Carlos María
Published: March 2020

En México, la Ley Federal de Transparencia y Acceso a la Información Pública contempla que la información relacionada con graves violaciones a derechos humanos y crímenes de lesa humanidad debe estar al alcance de quien la solicite, y por lo tanto no puede ser reservada. El presente artículo analiza el debate interamericano en torno a la califcación de distintos hechos como graves violaciones a los derechos humanos, así como las diversas aristas jurídicas y políticas que se desprenden de este tema. A partir de lo anterior, se discuten los estándares regionales y su incorporación nacional vía control de convencionalidad a través del análisis de seis resoluciones del INAI en torno al acceso a la información pública en los casos Tlatlaya y Ayotzinapa.
Estimación de la producción de metano entérico en ranchos de producción familiar de leche bovina en el sur del estado de Querétaro, México
Authors: Gómez Rosales Sergio , Angeles María De Lourdes , Romano Muñoz José Luis , Ruiz Corral José Ariel
Published: March 2020

El objetivo fue estimar el factor de emisión (FE) de metano (CH4) y pérdidas diarias de energía bruta (EB) convertida en CH4 (PCH4), por medio de ecuaciones de predicción del método nivel 2 del Panel Intergubernamental de Cambio Climático (IPCC) y con base en información técnica de ranchos del sistema familiar de producción de leche bovina. El estudio se realizó en 10 establos, y se obtuvo información técnica, tipo y cantidad de ingredientes ofrecidos al hato durante tres visitas en diferentes meses del año. La información técnica, junto con análisis de laboratorio del contenido de materia seca (MS) y EB de los ingredientes muestreados, se usó para estimar el consumo de MS y EB; usando la metodología del IPCC se estimó el FE y PCH4. Las mismas variables fueron estimadas usando las ecuaciones de predicción del IPCC. En vacas en ordeña el FE (81 y 70, kg CH4 año-1) y PCH4 (2.95 y 2.56, Mcal día-1) usando las ecuaciones del IPCC fueron similares a las obtenidas con las observaciones en ranchos; el FE ponderado por rancho fue similar (49.06 y 54.09, kg CH4 año-1), pero la PCH4 fue menor (1.11 y 1.97, Mcal día-1 P<0.01) usando las ecuaciones del IPCC con relación a las observaciones en ranchos. En general, a través del uso de información técnica de los ranchos fue posible estimar el FE y evidenciar una mayor PCH4 por rancho, y, en consecuencia, menor eficiencia energética, con respecto a la metodología del IPCC.
Áreas con aptitud ambiental para [Bouteloua curtipendula (Michx.) Torr.] en México por efecto del cambio climático

Published: March 2020

Las áreas de pastizal están expuestas a los efectos del cambio climático que se presentarán en las siguientes décadas, lo que provocará cambios en las comunidades vegetales, modificando a su vez los servicios y productos. La influencia del clima como determinante de la productividad primaria en los ecosistemas ha llevado a la realización de estudios para evaluar el impacto del cambio climático en comunidades vegetales mediante el uso de modelos de simulación. Las especies del género Bouteloua están entre las más importantes en los pastizales de México, por su calidad forrajera y sus características ecológicas; entre ellas sobresale el zacate Banderita [Bouteloua curtipendula (Michx.) Torr.]. El objetivo del presente estudio fue delimitar las áreas con aptitud ambiental de B. curtipendula por efecto del cambio climático en México. El análisis del clima futuro se hizo con los modelos de circulación general (MCG) HadGEM-ES y GFDL-CM3, con los rcp 4.5 y 8.5, para los periodos 2041-2060 y 2061-2080; para modelar los nichos potenciales de distribución se usaron datos de 407 sitios georreferenciados de colecta y 29 variables ambientales; mediante el modelo MaxEnt ambos MCG pronostican que el área con aptitud ambiental para B. curtipendula tendrá una disminución inicial entre 3.1 a 14.4 %, aunque después se recuperará e incluso aumentará hasta un 1.4 %. Las variables ambientales que más contribuyeron a explicar la distribución potencial de la especie fueron la altitud, el índice de humedad y la precipitación acumulada estacional de diciembre a febrero.
