The article presents the methodological foundations of posthumanism to address the technological object. It focuses on eight basic concepts: paradigmatic, machinic, archaeological, geological, material, vital, social, and ontological. Posthumanism seeks to overcome the subject-object dichotomy, build a society of machines, dismantle anthropocentrism, and deconstruct the concept of "human." The article questions the term "object" from different methodological foundations and proposes a non-anthropocentric representation of reality. Additionally, it mentions the importance of media archaeology in studying the immersion of communication machines in human history. The text presents a reflection on philosophical posthumanism and its relationship with materiality and the Anthropocene. It highlights the importance of understanding the materiality of technological objects and how it relates to discourse and agential reality. Philosophical posthumanism criticizes the anthropocentric burden of the human and its destructive role on the planet. The article presents the principles of philosophical posthumanism, which seeks to revise the relationship between the human and the non-human. It questions the primacy of the human over other creatures and proposes a posthuman ecology. It also mentions the importance of understanding the relationship between the technological object and the human through an ontology of media and machines. The article presents two philosophical currents related to posthumanism and transhumanism. The methodological proposal of Levy Bryant and Friedrich Kittler seeks to analyze the social relationships between media and machines through ontocartography and the ontology of media, respectively. While transhumanism seeks to enhance the human through science and technology, posthumanism criticizes anthropocentrism and proposes an alternative vision of the human that includes the non-human. The cited document is a list of bibliographic references that address the topic of posthumanism from different perspectives. It includes books, articles, and theses by various authors, such as Deleuze, Guattari, Ferrando, Habermas, Hayles, Kittler, Parikka, among others. These works explore concepts such as ontology, agency, politics, transhumanism, anti-humanism, and new materialisms. They also address topics related to technology, biomedicine, consciousness, and subjectivity. [Extracted from the article]

The aggregation of the plants was analyzed by four different methods to determine the degree of clustering, called square methods. The analysis was performed in the lower strata and top separately. The test failed to detect grouped distribution only to UTF1 and L1, whose values were not significantly different from one. The other morphospecies, except for the A2 group (various genres) have strongly grouped (significant at the 1% level). When we considered all species occurring in the area, the index found also revealed strongly clustered distribution. Performed the statistical analysis for choosing the parabolic model found that the log equation model y = bo + + b1ci b2ci², estimated basal area / ha more accurately for all forest types, except for the forest (Type II) as shown in Table 3. For this type of forest, the general model to the basal areas 01 set in relation to the DAPs compared to other models. A comparison between the adjustments made by the BETA functions and MEYER, where it shows the best-fit function MEYER. Analyzing the residues found that the MEYER function underestimated also the frequency of the trees in lower classes of DAPs, however, covering only the 50cm and 40 class, i.e., a lower amplitude than that covered by BETA function.

OBJECTIVE: To communicate probable cases of COVID-19 reinfection in medical personnel. MATERIALS AND METHODS: A prospective, observational study performed from June to October 2020, in which information was collected on the cases of doctors who had COVID-19 reinfection. RESULTS: Twenty-four doctors with COVID-19 reinfection were included. The most frequent comorbidity in this group of cases was overweight or obesity in 15 patients (62%); 7 individuals did not report any comorbidity and 3 of the cases suffered from systemic arterial hypertension, of which 2 also had obesity. CONCLUSIONS: The reinfection of COVID-19 is very likely and the SARS-CoV-2 virus does not provoke a perennial immunological memory in all infected individuals. [ABSTRACT FROM AUTHOR]

Introduction: The Tropical Dry Forest (TDF) is one of the most threatened ecosystems, in Colombia it has the greater extension in the Caribbean region, undergoing continuous transformation, causing the reduction of its coverage. Objective: To characterize the floristic diversity in terms of composition and structure in six TDF fragments in the lower and middle Sinú subregions of the Department of Córdoba. Methods: The methodology of Rapid Vegetation Sampling Plots - modified RAP was followed. Wealth and abundance were determined, The Importance Value Index by species and family, diametric and altimetric classes were constructed and the Fisher's a Diversity Index and S0rensen's Similarity Index were calculated. Results: 1 336 individuals were registered, grouped into 68 families, 161 genera and 273 species in the middle Sinú and 2 178 individuals (226 species / 151 genera / 59families) in the lower Sinú. The most important families by species richness were Fabaceae, Rubiaceae and Bignoniaceae, the highest abundance values were found in Fabaceae, Capparaceae and in the species Astronium graveolens Jacq. and Capparidastrum frondosum (Jacq.) Cornejo & Iltis. The distribution by diametric and altimetric classes presented an inverted J behavior. The bushes represented the dominant growth habit. Attalea butyracea (Mutis ex L.f.) Wess.Boer, Cavanillesiaplatanifolia (Humb. & Bonpl.) Kunth and Sterculia apetala (Jacq.) H.Karst. recorded the highest values of importance. Conclusions: The forests studied presented the floristic composition that characterizes the TDF in Colombia. The information obtained contributes to the integral management of the Tropical Dry Forest in Córdoba. [ABSTRACT FROM AUTHOR]

This paper is about group slurs, i.e., expressions that are prima facie associated with the speaker's conveyance of a derogatory feeling for a certain group of people identified in terms of their origin or descent ("spic"), race ("nigger"), sexual orientation ("faggot"), ethnicity or religion ("kike"), political ideology ("snowflake"), habits or ways of living ("whore"), etc. Our purpose is twofold: (i) explaining the non-truth-conditional or expressive meaning dimension in terms of a version of stereotype semantics, and (ii) applying a speech act theory to the original and paradigmatic derogatory uses of such terms.

Objective. Describe a tool to estimate demand for benznidazole and nifurtimox to treat Chagas disease, and report on its implementation in a group of Latin American countries. Methods. The project was carried out in the following stages: 1) development of a tool to estimate demand, and definition of the evaluation and decision variables to estimate demand 2) data collection via a questionnaire completed by representatives of control programs, complemented with data from the literature; 3) presentation of the tool, followed by validation, and adaptation by representatives of the control programs in order to plan drug procurement for 2012 and 2013; and 4) further analysis of the obtained data, especially regarding benznidazole, and comparison of country estimates. Results. Fourteen endemic countries of Latin America took part in the third stage, and a consolidated estimate was made. The number of estimated treatments, based on the number of tablets per treatment established in the regimen of reference was: 867 in the group under 1 year of age; 2 042 835 in the group from 1 to 15 years old; 2 028 in the group from 15 to 20 years old; and 10 248 in adults over 20. This means that it is possible to provide benznidazole to less than 1% of people for whom treatment is indicated. Conclusions. The development and systematic use of demand management tools can play a key role in helping to provide access to the anti-Chagas drugs. There is a significant gap between the projected demand for drugs and current estimates of prevalence rates. [ABSTRACT FROM AUTHOR]

Background: The alcohol withdrawal syndrome is a group of symptoms and signs that occur in alcoholic patients after discontinuation of alcohol consumption, severity of symptoms should be determined to guide the need for treatment, with a validated tool such as the CIWA-Ar scale. Sometimes the history of alcoholism is inexplicable, and suspected alcohol dependence is present, so that biochemical markers of alcohol consumption are helpful for diagnosis. Objective: To determine whether there is correlation between GGT levels and the severity of alcohol withdrawal syndrome. Material and method: A descriptive, cross-sectional, observational study was performed at two Hospitals of the SSDF in the Emergency and Internal Medicine services, during the period from October 2010 to May 2013. We included patients older than 18 years with the alcohol withdrawal syndrome. We excluded subjects diagnosed with hepatic insufficiency Child Pugh B and C, subjects with intake of other hepatotoxic products and subjects enrolled with neurological impairment or neuropsychiatric not associated with the alcohol withdrawal syndrome. We assessed the CIWA-Ar scale and measured biomarkers of alcohol consumption. The Pearson correlation coefficient was applied. Results: The study included 38 patients who met the inclusion criteria; all were men with an average age of 39 years. The average severity of the CIWA-Ar scale was 17.95 ± 8.7. No significant correlation was found between the level of GGT and the degree of severity of the alcohol withdrawal (r = 0.076, p = 0.651), no significant correlation was found between the ratio GOT-GPT (r = 0.197, p = 0.235), mean cell volume (r = 0.266, p = 0.1) and alkaline phosphatase (r = 0.119, p = 0.47) with the degree of severity of the alcohol withdrawal. Conclusion: GGT level had no significant correlation with the degree of severity of the alcohol withdrawal syndrome, indicating that there are other possible variables involved in the severity of this syndrome.

Background: The latex is a suspension derived from plants and fungi, their proteins are the antigens responsible for allergic sensitization. The medical staff is second in incidence of this allergy. objective: To assess the risk of latex allergy associated with surgical staff. Material and methods: A total of 120 health workers Xoco General Hospital were included in the period January 2011 to January 2012. There were 2 groups, the surgical area staff first and second medical personnel. We performed Prick skin test to latex and antigens associated with measurement of erythema and wheal, latex patch test and measurement of serum antigen specific. Results: The risk association of belonging to a surgical specialty and having a high antigen was OR = 3.8 ± 0.82, 95% CI 0.76-19.25, p = 0.10. The adjustment for potential confounding variables was obtained OR = 9.9 ± 1.20, 95% CI 0.88-110.85, p = 0.60. Conclusion: Prick test showed to be a suitable marker hypersensivity. The personal with surgical activity and greater exposure to latex were older and had a more elevated concentration of antigen compared to controls. [ABSTRACT FROM AUTHOR]

Background: Alcohol-related disorders are highly prevalent. Their presence is associated with high levels of psychiatric comorbidity and early mortality. It has been reported a prevalence of delirium tremens of 5% in patients with alcohol withdrawal syndrome (AWS). The severity of AWS assessed with CIWA-Ar scale, has proved useful for evaluation of symptoms of AWS. Objective: To evaluate the usefulness of CIWA-Ar scale as a method for diagnostic predictor of delirium tremens in patients with AWS. Patients and methods: Study cohort, prospective, longitudinal. We studied 100 patients with AWS and divided in 2 groups according to severity given by CIWA-Ar scale and were hospitalized and evaluated for presence of delirium tremens during hospitalization. results: We included 51 patients with mild to moderate AWS and 49 with severe AWS. Patients with delirium tremens were presence of 36 (36%), 15 (29.41%) had mild-moderate scores CIWA-Ar, and 21 patients (42.86) had severe CIWA scales. 64 patients (64%) did not develop delirium tremens during hospitalization, 36% (70.59%) were patients with mild-moderate CIWA and 28 (57.14%) with CIWA severe AWS (P = 0.16). Conclusions: The CIWA-Ar scale does not predict the development of delirium tremens, so it is not useful for diagnostic of delirium tremens in patients with AWS. [ABSTRACT FROM AUTHOR]

Background: In patients with hepatic failure have identified risk factors for upper gastrointestinal bleeding, including Child C liver failure and thrombocytopenia. We'll seek to determine the association between serum albumin and upper gastrointestinal bleeding in patients with Child-Pugh class B liver failure. Material and methods: We included patients with Child B liver failure with or without upper gastrointestinal bleeding. Demographic variables were recorded, it was determining blood count, blood chemistry, liver function tests and clotting times. For statistical analysis we used average percentage, standard deviation, Student's t test, χ², Fisher exact test and Spearman correlation. results: A total of 30 patients, 15 in each group. Albumin in the bleeding group had a mean 2.6 ± 0.68 mg/dL, in the other group was 2.7 ± 0.83 mg/dL (p = 0.29). The etiology was alcoholism in 100%. In the group of patients with gastrointestinal bleeding, 26.6% had esophageal varices DaGradi II, 46.6% had DaGradi III, 20% had DaGradi IV and 6.6% had DaGradi V. The odds ratio among patients who presented bleeding and serum albumin < 3 mg/dL was 1.3 (p = 1). Conclusions: In patients with Child B liver failure, hypoalbuminemia is not associated with bleeding. Variables such as ascites, creatinine and hemoglobin weren't associated with bleeding. [ABSTRACT FROM AUTHOR]

Background: The metabolic syndrome represents a clustering of several interrelated risk factors of metabolic origin that are thought to increase cardiovascular risk. It is still uncertain whether this clustering results from multiple underlying risk factors or whether it has a single cause. The evidence suggests that restricting sleep adversely affects metabolism. The restriction of sleep can damage glucose tolerance, alter levels of leptin and ghrelin increasing hunger and appetite, especially for foods with high carbohydrates content dense favouring the development of metabolic syndrome. Objective: To assess the relationship between hours of sleep, the components of the metabolic syndrome and the role of guard ABC, among residents of two health institutions. Methods: According to the criteria of the third report of the national cholesterol education program (NCEP-ATP III) designed a case-control study in two health institutions. 65 residents of second year or more, 33 with guards ABC Secretary of Health of the Government of Mexico City (SSDF) and 32 of specialties that do not have this complementary medical practice General Hospital of Mexico (HGM) for the period from March to May of 2008; was informed each resident, and after their acceptance was to collect information on the document, was given blood pressure, waist circumference, weight, height, BMI. Extraction fasting blood of least 8 hours to determine glucose levels, HDL cholesterol, triglycerides, and fasting insulin levels. Results: With less than five hours of sleep a day, as well as with more than eight, a higher susceptibility to have metabolic syndrome was found. Metabolic health status found in residents was: Obese BMI ≥ 27, the overall incidence was 40%, 54.5% and 25% in the group exposed and unexposed respectively with an odds ratio of 3.86 (95% CI 1.31 to 11.46) p= 0.01. Levels of triglycerides, with an odds ratio of 3.36 (95% CI 1.13 to 10.29) p= 0.02, hours of sleep, with an odds ratio of 2.82 (95% CI 0.97 to 8.33) p= 0.04; women with waist circumference, with an odds ratio of 18.0 (95% CI 2.25 to 158) p= 0.003, men with an odds ratio of 6.48 (95% CI 1.27 to 35.99) p= 0.02. Levels of HDL cholesterol women, an odds ratio of 1.33 (95% CI from 0.24 to 7.42) p= 1.00, men with an odds ratio of 1.38 (95%CI from 0.31 to 6.56) p= 0.02. Levels of insulin, an odds ratio of 4.80 (95% CI from 2.11 to 10.07) p= 0.05, HOMA an odds ratio of 5.54 (95% CI from 2.66 to 20.54) p= 0.12 Conclusion: The resident exposed to guards ABC has high incidence of obesity and metabolic syndrome, with an increased risk of 2.5 and 2.8 respectively. The sleep duration (= 5h) associated with the metabolic syndrome 1.8 greater risks in the exposed group; the associate hyperinsulinemia was 3.8 higher risks in the exposed group. We did not found direct relation between HOMA and guards ABC in this study. [ABSTRACT FROM AUTHOR]

Backgraund: Chronic urticaria is a multifactorial disease classified in three main groups: mechanical, autoimmune and idiopathic. So far we don't know the mechanisms that produces it, there are different theories and one of them is the presence of Helicobacter pylori. Objective: To establish the relation between chronic urticaria and Helicobacter pylori trough endoscopic and histopatological studies. Patients and methods: Seventy-two patients older than 18 years old, 36 with chronic urticaria and 36 controls with the same sex and age. Complete clinical history, hematical biometry, cutaneous determination of IgE and tests was made to each one. High panendoscopy with gastric biopsy was asked to practice Warthin Starry method and determine Helicobacter pylori existence. The statistical analysis was made with SPSS program, version 11, to establish the bivariated correlation in search of variables dependency. Results: In the group with chronic urticaria, there were 19 (52.8%) patients infected with Helicobacter pylori, and in the control group only 4 (11.1%). We found a χ2 with a value of 12.52 (p < 0.002). Conclusions: Association between chronic urticaria and Helicobacter Pylori is evident, so we propose a routinely scan for this microorganism in patients with the desease. [ABSTRACT FROM AUTHOR]
