Examen Neurológico del paciente comatoso
Authors: Garcia Ch. Carlos 
Published: July 2024

El examen de la persona inconsciente ( en estupor o coma) es de gran importancia dada la frecuencia con que se ve este tipo de pacientes en un hospital general. El hecho de que algunos de estos pacientes sean llevados por la policía o parientes a los servicios de urgencias sin ninguna información clínica, hace aún más difícil su diagnóstico. Por otra parte, el examen de pacientes en coma de causa conocidas (Trauma Craneano, meningitis, enfermedades metabólicas, etc), que están en tratamiento, es de gran importancia para evaluar el curso de la enfermedad y el pronóstico.

Pasteurización de la leche. Comentarios a una solución
Authors: Albán Holguín Julio 
Published: July 2024

La pasteurización puede ser definida como el proceso de hervir la leche a tales temperaturas y tantas veces cuantas sea requerido para destruir cualquier tipo de microórganismos presentes, causando el mínimo cambio en la composición, sabor y valor nutritivo. En el proceso clásico de pasteurización, la leche se retiene a una temperatura de 62.8°C - 56°C por no menos de media hora e inmediatamente es congelada a 10°C. La temperatura de uso casi universal es el llamado sistema "Altas temperaturas por corto tiempo" (HTST) en el cual la leche es retenida a temperaturas no menores de 71.7°C por 15 segundos e inmediatamente congelada hasta 5°C. Existen otras variantes, pero esencialmente el proceso es el mismo.

Authors: Pérez Milena , Cárdenas William , Ramírez Gloria , Pérez Mauricio , Restrepo Piedad 
Published: July 2024

Introduction: Bioequivalence or compared equivalence studies are used to demonstrate claims that the new product, named generic product, will have the same bioavailability as the reference product, named brand product. If two products are bioequivalent it means that they would expect to have the same efficacy and security. Bioequivalence is established by the statistical estimation of significant differences or not in the pharmacokinetics parameters of area under the curve (AUC) and maximum concentration (Cmax). In this case, bioequivalence will be evaluated and the bioavailability of valsartan will be compared. Valsartan is an agent antihypertensive and specific angiotensin II antagonist acting on the AT1 receptor subtype. Objective: The aim of this study was to evaluate the bioequivalence of two pharmaceutical products whose active principle is Valsartan, based on the comparison of the pharmacokinetic measures of rate and extent (in terms of required time) in which valsartan reaches the sanguineous circulation after a oral dose to 15 volunteers. Metodology: This was a randomized crossover double blind single-dose study on 15 male healthy volunteers aged between 19 and 28 years. The study was performed in two periods. Each treatment period consisted of a single-dose of 320 mg valsartan, with a wash-out time of 8 days between the first and second period. Plasma concentrations of valsartan were evaluated by HPLC/UV with method of addition of valsartan standard and losartan as internal standard. Results: Valsartan tablets formulation showed this pharmacokinetic parameters: AUC 44,893 µg/mlxh, Cmax 6,430.3 µg/ml and Tmax 2 h. Valsartan capsules formulation showed this pharmacokinetic parameters: AUC 44,963 µg/mlxh, Cmax 5,831.4 µg/ml and Tmax 2.5 h. Conclusion: The study showed no statistically significant differences in the plasma concentration levels after administration of the two formulations of valsartan: 80 mg tablets and 80 mg capsules. So, the design of the study and the application of the protocols chosen enabled the demonstration of bioequivalence between the products.

Published: July 2024

Introduction: Pediatric gastroesophageal reflux disease (GERD), has a high morbidity-mortality. The gold standard is the 24 hours pHmetry (pH24h). The objective is to determine the relationship between symptoms and parameters of pH24h. Methods: This is a comparative, descriptive, and retrospective study. N=35 children 5%) according to tables from the NCHS. From pH24h were taken: reflux index (RI), number of acid episodes, number of episodes >5 min and duration of the longest episode and association with symptoms. The statistical analysis was the Student’s test t, having p5 min 1.30±3.67 and the duration of the longest episode 9.36±20.06 min. There were no significant differences between the parameters of pH24h and the study groups (p>0.05). The respiratory group showed pH24h parameters more involved: IR 4.75±5.17%, number of acid episodes 79.17±79.76, number of acid episodes >5 min 2.29±4.97 and duration of the longest episode 15.0±27.04 min; the same as their nutritional status (p=0.003). Conclusion: There was no significant association between pH24h parameters and symptoms; however, respiratory symptoms group had a higher compromise of the pH24h parameters and nutritional status.

Published: July 2024

Objective: To determine whether single nucleotide polymorphisms found in the sequence of the β-2 (β2AR) adrenergic receptor are associated with spontaneous preterm delivery. Method: A case-control study in which the allelic, genotype, and haplotype frequencies of four polymorphisms, -47 C/T, -20 C/T, Arg16Gly, and Gln27Glu of the β2AR gene, were determined and compared between 35 women with preterm delivery (cases) and 105 women with term delivery (controls). The study was performed with patients of three hospitals in the city of Medellín, Colombia. The genomic DNA of peripheral blood was isolated, the segment of the gene was amplified by means of the chain reaction of polymerase (PCR), and the polymorphisms were determined by direct sequence method. Results: No significant differences for the allelic frequencies were found for polymorphic loci -47 C/T, -20 C/T, Arg16Gly, and Gln27Glu between the cases group (21.5%, 21.5%, 51.5% and 21.5%, respectively) and controls (21.5%, 21.5%, 57% and 21.5%, respectively; p>0.05). The genotype frequencies were also similar between patients with preterm delivery and those with term delivery (p>0.05 for all the genotypes). Only three of the 16 possible haplotypes (CCGG, TTGC, and TTAC), from the combination between the different alleles, appeared in the participants of this study. The haplotype frequencies were not significantly different between the compared groups either (p>0.05). Conclusion: No association was observed between preterm delivery and any of the polymorphisms or its haplotypes. These results do not support a role of the polymorphisms of the β2AR in spontaneous preterm delivery for these patients.

Published: July 2024

Se presentan 8 casos de Síndrome de Gilbert, 2 de ellos atípicos como les llaman algunos autores por presentar un aumento del pigmento de lipofuscina, aunque recientemente dicho aumento ha sido encontrado con mayor frecunecia en esta entidad. A los 3 primeros se les hizo biopsia hepática mientras que los restantes no fueron sometidos a este procedimiento. El estudio clínico es suficiente en muchos pacientes con este síndorme para establecer el diagnóstico. Se insiste en la benignidad del Síndrome de Gilbert puesto que no afecta la sobrevida normal del paciente.

Published: July 2024

Se demuestra una correlación positiva entre la prevalencia de gastritis atrófica en la población y el riesgo relativo de cáncer. La corelacion es más fuerte en las edades más tempranas, lo cual podrias explicar por qué las personas necidas en zonas de alta incidencia para cáncer gástrico conservan un riesgo alto a pesar de migrar a zonas de incidencia baja para la entidad. Una encuensta sobre hábitos alimenticios y dieta demostró que lo nacidos en las áreas de riesgo alto para cáncer y los pacientes con gastritis atrófica consumen más maíz, habas y mora y menos lechuga. En la búsqueda de factores ambientales se encontraron niveles altos de nitratos en manantiales y aljibes, fuentes de agua que son más usados en las áreas de riesgo alto. En base a estos hallazgos se plantea finalmente una hipótesis causal.

Published: July 2024

Recently, the effect of the blended learning strategy as compared with the face-to-face instruction in English language teaching has become a popular topic of research. This study focuses on the effect of implementation of Blended Learning (BL) approach in English Language Proficiency courses in Sulaimani city, Kurdistan Region of Iraq (KRI) on the language proficiency of both Elementary and Pre-intermediate level course participants. The study utilizes the quasi-experimental research design involving 104 Kurdish postgraduate students, who were allocated into a treatment group (blended learning) and control group (traditional face-to-face classroom), from these two levels. Thus, the main goal of this study is to investigate whether there are any significance differences in obtained language proficiency between participants of the two groups between groups and per level. The sampling has been taken from the population who were enrolled in an English language proficiency course at the public universities’ language centres in Sulaimani city. The experiment was carried out during an intensive course lasted for six weeks (100 hours) in which the classes of English language proficiency were taught four days per week. The experimental group was taught using blended learning (i.e. an equal combination of both virtual and face-to-face teaching) and the control group was only instructed with regular face-to-face teaching. Overall, the results show that the participants who were taught using both blended learning and traditional teaching methods outperformed the control group who were only taught in face-to-face classrooms. Additionally, the pre-intermediate experimental group achieved higher language performance than the pre-intermediate control group and improved their overall language proficiency slightly higher than the elementary group. The findings of this study bring further evidence and support for the integration of blending learning into English language classes, particularly in the language proficiency courses of the universities’ language centres. This study also has a number of teaching implications for EFL teachers which will be highlighted at the end of the paper.

Objectives:
The objective of this study was to assess the donor site morbidity in patients having anterior cruciate ligament reconstruction (ACLR) using peroneus longus tendon (PLT) autograft.

Methods:
A prospective cohort study was conducted at the orthopedic department of Pakistan Atomic Energy Commission General Hospital, Islamabad, from July 2021 to July 2023. A total of 150 patients aged between 20 and 40 years with an anterior cruciate ligament injury requiring ligament reconstruction were included in the study. Exclusion criteria included previous ankle ligamentous injuries, fractures or surgeries around the ankle, and high-risk sports like football. After the ACLR surgery, the patients were assessed for pain, range of motion (ROM), and muscle power in the 6th week, 3rd month, and 6th month. Return to jogging without discomfort at the ankle during 1st min of jogging was assessed at six months.

Results:
Of the 150 patients, 142 (94.6%) were male and 8 (5.4%) were female. The mean age of participants was 32.53 ± 4.78 years. Pain and loss of ROM around the ankle were reduced after six months compared to three months and six weeks, that is, P < 0.05. Muscle power was increased after six months (n = 152; 94.0%) (P < 0.001). In the 6th month, 133 patients (88.7%) were able to jog without discomfort around the ankle joint during the 1st min of jogging, but 17 patients (11.3%) started jogging after six months without discomfort at the ankle joint during the 1st min of jogging (P < 0.001).

Conclusion:
ACLR using the PLT autograft resulted in a good functional outcome, smooth rehabilitation with an early return to sports, and minimal complications at the donor site.

В эпоху глобального потепления изучение вечной мерзлоты становится особенно важно в связи с изменяющимся климатом. Проблема строительства городов в условиях вечной мерзлоты строительство решалась поэтапно, зачастую прямо на месте строительства. Было проведено множество исследований для изучения свойств вечномерзлых грунтов. Впоследствии они послужили основой для составления геокриологических карт. При изучении аварий строительных объектов на вечномерзлых грунтах было выявлено, что применение свайных фундаментов является оптимальным вариантом в условиях вечной мерзлоты. Они продемонстрировали полное отсутствие деформаций, осадки сваи и пучения.
In the age of the global warming, the permafrost study becomes particularly important due to the varying climate. The problem of building cities in permafrost conditions was solved gradually, frequently at the building place. Lots of investigations have been carried out to study the properties of permafrost soils. Subsequently, they served as the basis for the compilation of geocryological maps. As a result of the accidents study at the building places on permafrost soils was revealed that the use of pile foundations is the best option in permafrost conditions. They demonstrated a complete absence of deformations, pile settling and heaving.
