Published: July 2024

Introduction: Congenital malformations (CM) or morphologic defects at birthday, are seen almost everyday in the Hospital Universitario del Valle (HUV). Objectives: To determine the geographical distribution of HUV births with CM according to the place where pregnancy was sustained. Methods: A descriptive study was done using the database of The Latin-American Collaborative Study of Congenital Malformations in HUV. Population Under study was HUV newborns between March 01/2004 to February 28/2005. Results: Of 6,993 childbirths, a sample of 404 births was obtained, including cases of CM and controls, which 96% lived in socio-economic status 1, 2 and 3. The most frequent defects were extremities’ malformations (18.8%). The greatest number of childbirths, case and controls, where from commune 13 with 37 births (16.5%), followed by commune 14 (21 births, 9.4%), this commune was the only one in which the difference between cases and controls was significant (15 cases-6 controls), moreover, 3 cases of sirenomelia an unusual malformation prevalent in 1 of 100,000 births were identified in this commune. Conclusions: Factor or factors predisposing to main malformations in commune 14 should be identified.

Authors: Siachoque Heber , Ibáñez Milcíades 
Published: July 2024

Objective: To evaluate the immunogenicity of Hepavax-Gene recombinant hepatitis B vaccine in INML workers since the last administered doses. Methods: Cross-sectional study on 603 health workers with at least three administered recombinant vaccine doses. Antibody levels (anti-HBs) were measured using the ELISA technique during December 2000 and January 2001, taking into account that the last dose in the vaccination varied between 1 and 6 years. Results: A total of 344 men and 259 women with an age mean of 38.8±7.3 years were studied. Protection levels were found in 90.7% (>10 U/l), decreasing significantly with the worker’s age (p< 0.001) and with the vaccine last dose administration time (p< 0.01). Health workers with four doses compared to those with three doses had a 4.7% higher protection (antibody median 209.8 vs. 130.07, p< 0.001). No association was found with gender (p=0.463), smoking (p=0.331) and blood exposure (p=0.433). Multivariate analyses found that no protection associated only with age (40-44 years HR=2.37, CI 95%:1.18,4.78 and >45 years HR=3.58, CI 95%: 1.83,6.99). Conclusions: Although Hepavax-Gene recombinant hepatitis B vaccine (anti-HBs) has a high effectiveness in the health workers (90.7%) it presents a decrease in protection levels related to a higher worker’s age and a long vaccine last dose administration time.

Authors: Piña Julio Alfonso , Corrales Andrés Ernesto , Rivera Blanca Margarita 
Published: July 2024

Fundament: A cross-sectional study was carried out with the main objective to identify if psychological variables including knowledge, belief, and motivation predicted two prevention behaviors related to HIV infection: «To postpone a sexual intercourse» and «Condom use intention». Method: From an original sample of 648 students of two institutions located in Hermosillo, Mexico, we worked with a subsample of 328 students whom reported no sexual experience. For data analysis descriptive statistics, the Pearson’s x2 and a logistic regression analysis were used. Results: The Pearson’s x2 showed significant differences in both behaviors: those who have the opportunity to involve in a sexual relationship and they avoid it (x2 [2]=45.378; p=0.000), as well as those who have condom use intention (x2 [2]=235.622; p=0.000). The logistic regression analysis revealed that one type of motivation predicted the behavior to avoid a sexual relationship with penetration (x2 [9]=33.805; p=0.000), if well another type of motivation predicted the behavior condom use intention (x2 [8]=18.069; p=0.021). Conclusions: The role of the variable motivation in the prevention of HIV infection programs is discussed.

Authors: Onzaga Ingrid L. , Rincón Javier , Guerrero Mario F. 
Published: July 2024

Introduction: This study shows the vasorelaxant profile in isolated aortic rings from Wistar rats of the ethanolic extract and the acetylated flavonoid fraction obtained from Calea prunifolia, specie used in Colombian folk medicine for the treatment of arterial hypertension. Objectives: To study possible action mechanisms implicated in the response induced by the ethanolic extract and the acetylated flavonoid fraction obtained from C. prunifolia in isolated aortic rings. Methodology: After verifying the hypotensive effect of the etanolic extract in anaesthetized rats, the response induced by the extract and the acetylated flavonoid fraction (1 μg/ml-100 mg/ml) in isolated aortic rings from Wistar rats contracted with KCl (80 mM) or phenylephrine (1 μM) was studied. Then, the effect of the extract and the fraction was assessed in deendothelized rings contracted with KCl or in intact rings contracted with KCl (80 mM) and preincubated with one of the following substances: L-NAME (0.1 mM, NO-sintasa inhibitor), methylene blue (1 μM, guanyl ciclasa inhibitor), glibenclamide (1 μM, K+ATP channel inhibitor), atropine (30 μM, muscarinic antagonist), propranolol (1 μM, b receptor blocker), or indomethacin (1 μM, COX inhibitor). The response induced in rings contracted with CaCl2 in Krebs solution without Ca2+ also was analised. Results: The ethanolic extract elicited a dose-response (5-75 mg/kg. iv.) decrease in the blood pressure levels without affecting heart rate in anaesthetized rats. Both, extract and fraction relaxed KCl (80 mM) and phenyle-phrine (1 μM) precontracted isolated aorta rings with IC50 of 35 and 67 mg/ml against KCl and 34 and 66 mg/ml against phenylephrine, respectively. Rings exposed to CaCl2 in Krebs’ solution without Ca2+ showed the better response induced by both extract and fraction. Discussion: These results suggest that acetylated flavonoid compounds play a key role in the vasorelaxant effect induced by C. prunifolia by mechanisms mainly related to calcium channels antagonism.
Pulp microbiology of complete teeth with idiopathic apical lesions.
Authors: Rodríguez Patricia , Calero Jesús Alberto 
Published: July 2024

Introduction: Periapical changes named as lesions, in teeth with full crown integrity and without history of trauma, do not show a clear aetiology. Objective: To determine the presence of microorganisms in pulp dental tissue will clarify the cause of its death and therefore the damage to periodontal tissues. Materials and methods: From people between 10 and 39 years old, 23 teeth were selected. The samples were taken with paper points and 0.8 sterile files, and were transported in VMGA III medium, to be processed in the following 24 hours after they were taken and sowed in Brucella-agar. Results: The most affected teeth were upper central incisors, 43.8%. From the 23 studied teeth, microbiological grow was seen on 20 teeth. The following microorganisms species were identified: Fusobacterium spp., 25%, Eubacterium spp., 15%; Peptostreptococcus spp., 10%; Campylobacter spp., 10%; gram negative enteric bacteria, 10%; Porphyromonas gingivalis, 10%; Prevotella intermedia, 5%; Eikenellia corrodens, 5%; Dialister pneumosintes, 5%; and yeasts, 5%. There was no growing evidence of Actinomyces actinomycetemcomitans, Tanerella forsythensis and Streptococcus β hemolytic. Discussion and conclusions: Sound pulp dental tissue is sterile; an injury over it will cause its inflammation, degeneration, death and bacterial contamination. Results in the present study clearly show the presence of microorganisms in closed apical dental lesions of endodontic origin. In same manner, it was seen that a great part of microorganisms species found can be regarded as periodontal pathogens. This could suggest a management with an endodontic, a periodontic and a pharmacological combined treatment.

Published: July 2024

Introduction: The prenatal exposition to misoprostol during the first trimester has been associated to congenital malformations. In the last years it has been reported an increase in the detection of defects by vascular disruption associated with prenatal exposition of misoprostol. Methods: It is described the phenotypic characteristics of 7 new patients born in Cali, who consulted the dysmorphology clinic of the HUV since May of 2005 due to the presence of congenital malformations associated with prenatal exposition to misoprostol. Results: The final diagnoses of the 9 patients included in this study are: Moebius syndrome (3), hypoglosia-hypodactilia syndrome (1), cyclopia (1), gastroschisis (1), microcephaly (1), Klippel Fiel sequence (1) and hydranencephaly (1). The exposition to misoprostol appeared during gestation weeks 4 to 14 to doses between 800 and 1,000 mg, Discussion: Recently 11 cases of congenital malformations related to the exposition to misoprostol had been reported in this hospital. These cases were discovered in a period of 4 years; now the present paper reports 7 new cases in a period of 2 years. This fact suggests an increasing tendency to congenital malformations due to the association with misoprostol used as an abortive during the first pregnancy trimester. The observed malformations do not correspond only to Moebius syndrome, but to other vascular disruption defects like gastroschisis, hypoglosia-hypodactilia and hydranencephaly.

Authors: Escobar J A , Belsey M A , Medina P , Dueñas A 
Published: July 2024

En 99 pacientes con meningitis tuberculosa estudiados en Cali, Colombia, el tratamiento con esteroides (en unión de drogas antituberculosas) mostró ser más efectivo en la reducción de la mortalidad que la terapia por drogas antibacterianas solas. Los resultados posteriores sugieren que las dosis bajas de esteroides (1 mg/kg) de prednisona diariamente durante 30 días) son tan igualmente efectivas en el tratamiento de la enfermedad como las dosis altas (10mg/kg de prednisona al comenzar tratamiento, gradualmente reducido en un período de 30 días). Estos resultados se basan en el análisis secuencial de parejas comparativas, un método estadístico particularmente apropiado para ensayos clínicos.
Perejil. (Petroselinum savitum) y malformaciones congénitas
Authors: Aragón Jorge A 
Published: July 2024

Con el objeto de estudiar la relación entre el perejil (Petroselinum savitum) y la produccion de malformaciones congénitas se administró extracto de perejil por diferentes días, a 330 hembras adultas de ratones albino-suizos divididos en 11 grupos de 30 animales cada uno. El día 21 de gestación, bajo anestesia, fueron extraídos los fetos y examinados macroscópicamente. Se encontraron acranias, anencefalias, meningoceles y onfaleceles en un porcentaje aproximado de 1%, mientras que los 2 grupos controles de 30 animales cada uno fueron negativos. Estos hallazgos sugieren que cuando se usa el perejil con fines abortivos, durante la gestación, y el aborto no se realiza, origina la posibilidad de una malformación congénita.

Aprovechando el cambio de conducta en el manejo de las heridas penetrantes de abdomen realizado en el Hospital Universitario del Valle el 1o. de Noviembre de 1973 se estudairon todos los casos de tales heridas atendidas en los años inmediatamente anterior y posterior a esa fecha. La conducta de realizar laparotomía rutinaria en toda herida penetrante de abdomen fue reemplazada por una conducta de laparotomia selectiva en caso de aparición se signos abdominales positivos. El porcentaje de pacientes a quienes se les practicó laparotomía bajó de 79,4 (177/223) en el años antes a 49,4 (163/330) en el año después. El porcentaje de laparotomía en blanco bajó de 26 a 5 al comparar los mismo períodos. Aunque la frecuencia de complicaciones fue mayor en el segundo período, se considera que la conducta selectiva es más favorable para los pacientes.

A Study of Nonverbal Persuasion in TED Talks
Authors: Falih Ali Mahdi , Ahmed Muhammed Badeaꞌ 
Published: July 2024

This study investigates the realm of nonverbal communication and its persuasive impact in the context of TED talks. Nonverbal communication plays a significant role in effectively conveying persuasive messages, especially in TED talks, which are considered a useful database for the study. Surprisingly, little researches and studies have investigated the role of nonverbal behavior in persuading and influencing others. The study aims to find the most common body movements in TED talks, analyze the common movements kinetically to have a better understanding of these movements, and investigate the nonverbal persuasiveness of the selected movements. The study adopts a model consisting of Birdwhistell's (1952) kinesic analysis model and Andre et al.'s (2011) nonverbal persuasion analysis model. Final results reveal that (1) hand movement is the most common type among other types of movements, (2) the persuasiveness of nonverbal communication is achieved by basing on the following persuasive body behaviors: importance, emotion, certainty, the sender’s competence, evaluation, and the sender’s benevolence, (3) body language, such as hand gestures, head nods, and facial expressions, can be broken down into smaller parts, these smaller parts, known as the kinemorph, kineme, and kine, make the body movements understandable.
Religious Identity and Deixis in Friday Sermons: A Sociopragmatic Study
Authors: Jassim Rafid Mohammed , Ali Hadeel Kamil 
Published: July 2024

As a linguistic phenomenon, deixis holds significant connotations for how discourse, whether verbal or written, is interpreted, especially when it requires understanding the referential and contextual aspects of language in a framework of mutual communication. Deixis assumes a pivotal role in the conveyance of religious messages characterized by guidance and instructional content in the domain of Islamic Friday sermons, thereby contributing significantly to the establishment of religious identity and fostering a sense of connection between the preacher and the audience. Based on Levinson's theoretical viewpoints and sociopragmatic background, the current study examined the active effect of deixis used in Friday sermons delivered by some Muslim preachers. Hence, different types and frequencies of deixis categories have been comprehensively examined. Additionally, the study aimed to elucidate the reasons that led to the predominant type of deixis in both languages English and Arabic, in line with Levinson's focus on communicative choices. From reliable websites, ten sermons in both Arabic and English were downloaded. This study employed both qualitative and quantitative methodologies to examine the data. The analysis involved examining (80) utterances, with English Islamic Friday sermons employing deixis expressions (133 times) and Arabic Islamic Friday sermons using them (93 times). The results indicated that discoursal and temporal deictic expressions were frequently observed in both languages with the personal category being the most prevalent.

Tapestry of Cultures in Derek Walcott’s Poetry: A Transcultural Reading
Authors: Abbas Yasser Thamer , Aldoory Arwa Hussein 
Published: July 2024

Walcott, through his searches for the history of his original nation, seeks to face the racial conflicts that impacted his cultural formation; he does celebrate the hybridity that becomes an integral part of his identity through crossing- national transit. It is through his constant traveling that, continuously, leads him to experience other nations, cultures, identities. His poetry comes to be a witness for a more cosmopolitan construction of individuality. Walcott, in his early poetry, shows his endeavors to understand the culture and the racial challenges of his origin, yet it seems that he comes to no resort. In his later poetic volumes, he seems to come to a better realization of his Caribbean identity that fell under colonial influences. Thus, Walcott comes to accept that his own Caribbean roots can go beyond its origins. This can be called transcultural approach which has developed in the last few decades, not only to embrace alterity, but also to encourage interconnectedness and empathy with the Other. Transculturalism challenges the traditional notions of culture, belonging, and identity. The purpose of this study is to explore Walcott’s poetry that reveals the poet’s perspective on national and cultural identity. It argues that, though Walcott’s poetry is deeply rooted in the Caribbean culture, traditions, and national inheritance, yet it transcends the national and cultural limits to celebrate the hybridity of the Caribbean present identity. Walcott’s constant traveling created a poetry that goes beyond its national borders to see in displacement of the Caribbean people and the diaspora as a means to develop a better communication with the world. Therefore, Walcott is quite liberal in his cultural perspective regarding identity politics.

Published: July 2024

Once the pandemic started, there were no clues regarding overall COVID-19 infections. There are no studies that demonstrate the effects of COVID-19 on skin surface pH, moisture, sebum, and temperature in terms of gender differences and body mass index (BMI) among infected people. The goal of this study was to investigate some of the skin biophysical scores of patients infected with COVID-19 and evaluate the impact of gender differences and the body mass index on them. Skin surface sebum, pH, temperature, and hydration (moisture), were measured in 30 COVID-19 patients using employing non-invasive portable devices. Insignificant effects of gender differences and BMI on skin biophysical properties were observed. In addition, females showed higher skin biophysical characteristics than males. Moreover, obese patients had higher skin biophysical parameter values than normal-weight patients. However, all the study results were statistically insignificant (p > 0.05). Further investigations are required to recognize other skin biophysical parameters such as transepidermal water loss and elasticity that may aid in the early identification of skin damage in COVID-19 patients.
