RESUMO
The prevalence of Heart Failure is growing alarmingly; its treatment consumes health resources and affects the quality of life of patients. To describe the changes in NYHA functional Class, ejection fraction, hospitalizations, and mortality after 8 years of follow up in a multidisciplinary heart failure program in Colombia as a model for lower and middle income countries. An observational study was performed with the retrospective analysis of the information. 1757 patients were included, The NYHA functional class at the beginning of the program was: NYHA I 23.5%, NYHA II 50.3%, NYHA class Improvement was observed at the end of the follow-up with an increase in the percentage of patients in Functional Class NYHA I and II. The reduction in hospitalizations were 35% less (mean: 0.68 ± 0.95, P < 0.0001), a reduction in the length of stay in the hospital was 13.2% (before: 4.46 ± 7.16, after 3.87 ± 8.1 days, P < 0.001). The total mortality after eight years of follow-up was 6.6 % (nâ¯=â¯116). Multidisciplinary follow-up in Heart Failure (HF) programs improves Functional Class and EF, decreases hospital admissions as well as hospitalization and the length of stay. This is a very simple and successful model of care for this disease that can be implemented for countries of lower- and middle-income countries.

The effect of different non-conventional carbon sources was studied in the submerged culture of Lingzhi or Reishi medicinal mushroom, Ganoderma lucidum, for simultaneous production of mycelial biomass, bioactive ganoderic acid, and polysaccharides, in less time, using non-conventional carbon sources to minimize the high costs of current culture media. The optimal medium composition was defined as (g/L): 50 of barley flour, 0.2 of KH2PO4, 0.1 of MgSO4â±7H2O, and 1 NH4Cl. Cultivated under this complex culture medium, the mycelial biomass production was 23.49 ± 0.37 g/L; the extracellular polysaccharides production was 2.72 ± 0.11 g/L; the intracellular polysaccharides production was 2.22 ± 0.06 g/L; the ganoderic acids production was 299.67 ± 11.63 mg/L. One liter of culture medium developed in this project was priced at USD $ 0.11 if barley flour is used as carbon source or $ 0.13 with oat flour in order to get a good amount of products of interest.

In addition to plant-derived, fungal pigments have become an alternative in respect to synthetic ones. Besides Monascus sp., several pigment-producing fungi do not have culture conditions well-established yet. In this research, media composition, light wavelength and co-culture were evaluated, results were reported in Absorbance Units per gram of biomass (AU/Bgr). For Fusarium oxysporum a C:N ratio above 7 was advantageous, using both complex and defined media; blue LED light increased the AU/Bgr value from 18013 to 344; co-culture did not enhance pigment production. In Aspergillus chevalieri a high C:N ratio with glucose as carbon source was ideal. When exposing cultures to light, UV and red light gave the highest pigmentation; moreover, differential UV-VIS spectra in all wavelengths suggested production of additional pigments. Particularly a pigment observed when cultured in green light was also found in co-culture with yeast and there was an improvement of AU/Bgr value of 52549%. This is the first report regarding light effect and co-culture for these fungi, as well as C:N ratio for A. chevalieri.
RESUMO
The use of agro-industrial waste for application in the obtention of products with high added value has become a trend in recent years, especially in tropical countries whose main economic sector is agricultural exports. In the present study, an applicable method to food industry of extracting proteolytic enzymes from dryed papaya and pineapple residues by convection was developed. Different to other scientific reports the heat treatment at 40⯰C of waste residues, to reach 20% moisture, allowed an increase in total soluble protein content and did not alter the proteolytic activity of the extracts when phosphate buffer pH 7.0 was used as solvent. In the residues evaluated as candidates for the extraction of endopeptidases, we observed that green dried papaya peel and dried pineapple core, had higher activity values (914.34⯱â¯25.47â¯U/mg and 2152.36⯱â¯75.99â¯U/mg, respectively). These results, combined with one-dimensional electrophoresis and protein identification methods by MALDI TOF-TOF, showed the presence of signal peptides characteristic of papain, bromelain and other endopeptidases previously reported in extracts of fresh papaya and pineapple residues. These findings show that the drying of the residues by convection does not alter neither the activity nor the structure of the proteolytic enzymes. Finally, it is confirmed that the use of 20% ammonium sulfate as a precipitating agent allows to reach an efficiency of 74% in different work scales the use of purification and identification protocols in a more adaptable way, making them the most promising waste in Colombia, due to its potential for the production of bromelain on a larger scale.
RESUMO
Introducción. Las infecciones de transmisión sexual (ITS) son y seguirán siendo un serio problema de salud pública en todo el mundo según los datos de la OMS, con el agravante que la mayoría de los casos son asintomáticos y, además, no existe otro reservorio distinto al humano. El diagnóstico se puede realizar con pruebas tradicionales y moleculares, estas últimas incluyen la reacción en cadena de la polimerasa (PCR), de las cuales existen varios tipos, entre ellas, la PCR múltiple que tiene la capacidad de detectar ITS polimicrobianas a partir de una sola muestra. El objetivo de este estudio fue establecer cuáles fueron las infecciones de transmisión sexual más frecuentes en diferentes grupos de pacientes, así como determinar la utilidad del uso de la técnica de PCR múltiple en el diagnóstico de las ITS. Metodología. Se trata de un estudio observacional de corte transversal realizado entre los años 2021 y 2022 con pacientes que acudieron al servicio de diagnóstico del Laboratorio Clínico VID por sospecha de ITS. Las muestras recolectadas fueron evaluadas utilizando una prueba comercial basada en la técnica de PCR múltiple e hibridación. Las muestras procesadas fueron: orina e hisopados de endocérvix, uretra, recto, faringe y úlceras. Resultados. Se estudiaron 1.027 pacientes, de estos, 228 (22,2 %) fueron positivos para diferentes agentes de trasmisión sexual, distribuidos así: 50 (21,9 %) mujeres, 129 (56,6 %) hombres heterosexuales y 49 (21,5 %) hombres que tenían sexo con hombres (HSH). La edad promedio de las mujeres fue 30 años, y la de ambos grupos de hombres fue 36 años. Los microorganismos más frecuentemente identificados en mujeres fueron: C. trachomatis (A-K) en 28,6 %, seguido de virus herpes simplex tipo 2 (VHS-2) en 26,8 % y N. gonorrhoeae en 17,9 %. En hombres heterosexuales fueron C. trachomatis (A-K) en 37,5 %, N. gonorrhoeae en 21,5 % y VHS-2 en 18,7 %. En HSH fueron C. trachomatis (L1-L3) en 32,7 %, seguido de N. gonorrhoeae en 27,6 %, y de C. trachomatis (A-K) y VHS-2, ambos en 13,8 %. En 11 hombres heterosexuales, 8 HSH y en 6 mujeres, se identificó infección polimicrobiana. Conclusiones. C. trachomatis (A-K) fue el microorganismo más prevalente causante de ITS, seguido de N. gonorrhoeae en ambos grupos de hombres, y de VHS-2 en las mujeres, muy similar a lo reportado a nivel mundial. La prueba de PCR múltiple permite la detección de infecciones polimicrobianas comúnmente asociadas a ITS y el diagnóstico es preciso y confiable, incluso en pacientes asintomáticos
Sexually transmitted infections (STIs) are and will continue to be a serious public health problem throughout the world according to WHO data, with the aggravating factor that most cases are asymptomatic and, furthermore, there is no other reservoir other than humans. The diagnosis can be made with traditional and molecular tests, the latter include the polymerase chain reaction (PCR), of which there are several types, among them, multiplex PCR that has the capacity to detect polymicrobial STIs from a single sample. The objective of this study was to establish which were the most frequent sexually transmitted infections in different groups of patients, as well as to determine the usefulness of the multiplex PCR technique in the diagnosis of STIs. Methodology. This is an observational, cross-sectional study carried out between 2021 and 2022 with patients who attended the VID Clinical Laboratory for suspected STIs. The collected samples were evaluated using a commercial test based on the multiplex PCR technique and hybridization. The samples processed were: urine and swabs from endocervix, urethra, rectum, pharynx, and ulcers. Results. The study included 1,027 patients, of these, 228 (22.2%) were positive for different sexually transmitted agents, distributed as follows: 50 (21.9%) women, 129 (56.6%) heterosexual men and 49 (21.5%) men who had sex with men (MSM). The average age of the women was 30 years, and that of both groups of men was 36 years. The microorganisms most frequently identified in women were: C. trachomatis (A-K) in 28.6%, followed by herpes simplex virus type 2 (HSV-2) in 26.8% and N. gonorrhoeae in 17.9%. In heterosexual men they were C. trachomatis (A-K) in 37.5%, N. gonorrhoeae in 21.5% and HSV-2 in 18.7%. In MSM they were C. trachomatis (L1-L3) in 32.7%, followed by N. gonorrhoeae in 27.6%, and C. trachomatis (A-K) and HSV-2, both in 13.8%. Polymicrobial infection was identified in 11 heterosexual men, 8 MSM, and 6 women. Conclusions. C. trachomatis (A-K) was the most prevalent STI-causing microorganism, followed by N. gonorrhoeae in both groups of men, and HSV-2 in women, very similar to that reported worldwide. The multiplex PCR test allows the detection of polymicrobial infections commonly associated with STIs and the diagnosis is accurate and reliable, even in asymptomatic patients

Abstract Introduction Patient reported outcomes establish the patient's own perception about his/her health and enable the development of policies designed to improve health/disease processes. These are particularly helpful in the case of diseases with a significant impact on the patient's quality of life. Objective To compare the quality of life scores assessed using the EQ-5D-5L questionnaire in patients undergoing cephalic duodenopancreatectomy (Whipple procedure) and laparoscopic cholecystectomies in the same hospital. Methodology Retrospective cohort trial between July 2018 and February 2020. Patients programmed for cephalic duodenopancreatectomy were included, regardless of the type of pathology, and over 18 years old. Patients with carcinomatosis or vascular infiltration were excluded. The EQ-5D-5L was administered following Whipple surgery and compared against a control group (laparoscopic cholecystectomy). The demographic characteristics, the diagnosis, hospital stay and 60-day mortality were assessed. Results A total of 68 patients were included. The most frequent diagnosis was pancreatic cancer (30 %) in the Whipple group and lithiasis (100 %) in the control group. In the five dimensions assessed, there were no differences in terms of mobility (OR: 0.41, 95 % CI [0.30-0.57], p = 0.103) and in terms of personal care (OR: 0.42, 95 % CI [0.32-0.58], p = 0.254). There was a difference in daily life activities (OR: 0.38, 95 % CI [0.27-0.54], p = 0.017), pain/malaise (OR: 2.33, 95 % CI [0.99-5.48]), p = 0.013 and anxiety/depression (OR: 0.39, 95 % CI [0.28-0.55], p = 0.019). The overall health perception was 80 points for Whipple (IQR 60-90) vs. 100 points for the control group (IQR 90-100). Conclusions Patients undergoing a Whipple procedure experience a health perception slightly lower than patients undergoing laparoscopic cholecystectomy. This difference may be associated with increased pain, anxiety/depression and a reduction in their activities of daily life. The administration of the EQ-5D-5L questionnaire to measure quality of life is a friendly tool that used be used routinely to plan activities aimed at improving medical care.
Resumen Introducción Los desenlaces informados por el paciente permiten establecer cuál es la percepción que tiene de su salud y crear políticas que mejoren procesos en salud/enfermedad. Son particularmente útiles en enfermedad que afectan la calidad de vida de forma importante. Objetivo Comparar las puntuaciones de calidad de vida evaluadas mediante el cuestionario EQ-5D-5L en pacientes sometidos a duodenopancreatectomía cefálica (procedimiento de Whipple) y colecistectomías laparoscópicas en el mismo centro hospitalario. Metodología Estudio de cohorte retrospectivo entre julio de 2018 y febrero de 2020. Se incluyeron pacientes programados para duodenopancreatectomía cefálica independientemente del tipo de patología y mayor de 18 años de edad; se excluyeron pacientes con carcinomatosis o infiltración vascular. Se aplicó el cuestionario EQ-5D-5L después de cirugía Whipple y se comparó con un grupo control (colecistectomía laparoscópica). Se evaluaron características demográficas, diagnóstico, estancia hospitalaria y mortalidad a 60 días. Resultados Se incluyeron 68 pacientes. El diagnóstico más frecuente fue cáncer de páncreas (30 %) en el grupo Whipple y litiasis (100 %) en el grupo control. En las 5 dimensiones evaluadas no hubo diferencias en movilidad (OR: 0,41, IC 95 % [0,30-0,57], p = 0,103) y en cuidado personal (OR: 0,42, IC 95 % [0,32-0,58], p = 0,254). Se encontró diferencia en actividades cotidianas (OR: 0,38, IC 95 % [0,270,54], p = 0,017), dolor/malestar (OR: 2,33, IC 95 % [0,99-5,48]), p = 0,013 y angustia/depresión (OR: 0,39, IC 95 % [0,28-0,55], p = 0,019). La percepción general de salud fue 80 puntos para Whipple (RIQ60-90) vs. 100 puntos para el grupo control (RIC 90-100). Conclusiones Los pacientes sometidos a Whipple presentan una percepción de salud ligeramente menor que los pacientes de colecistectomía laparoscópica. Esta diferencia puede estar relacionada con el aumento en dolor, angustia/depresión y disminución en actividades cotidianas. La aplicación del cuestionario EQ-5D-5L para medición de calidad de vida es una herramienta fácil de aplicar que debería realizarse rutinariamente para planear intervenciones dirigidas a mejorar la atención médica.

RESUMO
Abstract Background: The administration of perioperative fluids is a controversial issue that can be associated with the development of postoperative pancreatic fistula (POPF) after Whipple procedure. Objective: To evaluate whether intraoperative fluid management along with Enhanced Recovery after Surgery (ERAS) protocols affect outcomes following major pancreatic resection. Methods: A retrospective cohort study was conducted from January 2012 to January 2017, collecting all patients scheduled for duodenopancreatectomy (DP). Patients were divided into 2 groups according to the use of ERAS protocols and the use of a fluid therapy algorithm. Results: A total of 67 patients were analyzed, 49.3% of which were females. The most frequent diagnoses were Pancreatic Cancer n:48 (71.6%), followed by intraductal papillary mucinous neoplasm n:6 (9%). The majority of patients were in the ERAS group n:46 (68.7%); 80.4% and 95.7% of them did not develop pancreatic fistula or delayed gastric emptying (DGE) respectively, and the incidence for both was 11.94%. Fluid therapy was below 5000 mL (P=0.001) with blood loss less 300 mL (P = 0.001) in the ERAS group. The length of stay was shorter in the ERAS group (7 days, interquartilel range 5-12, P < 0.001). No differences in 30 days mortality were found. Conclusion: The implementation of ERAS protocols in DP did show a decrease in intraoperative blood loss, intravenous fluids therapy, need for transfusion, DGE, or total hospital stay. However, intraoperative fluid restriction in DP did not show a reduction in the development of POPF.
Resumen Introducción: La administración de fluidos durante el perioperatorio es un tema controvertido que puede asociarse a complicaciones como la fístula pancreática después de realizar el procedimiento de Whipple. Objetivo: Evaluar si los protocolos de manejo de líquidos dentro de las recomendaciones de recuperación acelerada después de cirugía (ERAS) afectan los desenlaces después de intervención pancreática mayor. Materiales y métodos: Se realizó un estudio de cohorte retrospectivo entre enero de 2012 y enero de 2017. Se recopilaron todos los pacientes a quienes se les practicó duodenopancreatectomía. Se dividieron en dos grupos según el uso de protocolos ERAS y el uso de algoritmos para terapia hídrica. Resultados: Se analizaron 67 pacientes, el 49,3% correspondió al sexo femenino. Los diagnósticos más frecuentes fueron cáncer de páncreas n: 48 (71,6%), seguido de neoplasia mucinosa papilar intraductal n: 6 (9%). La mayoría de los pacientes se encontraban en el Grupo ERAS n:46(68,7%).En dicho grupo, el 80,4% y el 95,7% no desarrollaron fístula pancreática o retraso del vaciamiento gástrico y la incidencia fue del 11,94%, respectivamente. La terapia hídrica estuvo por debajo de 5000 ml (p = 0,001) con una pérdida sanguínea inferior a 300 ml (p=0,001) en el grupo ERAS. La estancia hospitalaria fue más corta en el grupo ERAS (7 días, rango intercuartil [RIC] 5-12, p =<0,001). No hubo diferencias en la mortalidad a 30 días. Conclusión: La implementación de protocolos ERAS en la duodenopancreatectomía mostró una menor pérdida sanguínea, menor terapia hídrica, menor necesidad de transfusión, menor retraso del vaciamiento gástrico y menor estancia hospitalaria. Sin embargo, la terapia hídrica restrictiva no redujo el desarrollo de fístula pancreática postoperatoria.

Abstract Background: Hepatopancreatobiliary surgery (HPB) has been able to reduce morbidity and mortality over the past 30 years, as a result of technological breakthroughs, high-volume centers, and the implementation of multidisciplinary groups with fast recovery protocols. Objective: To compare the impact of implementing fast recovery guidelines in patients undergoing HPB surgery. Methods: We conducted an observational retrospective study collecting medical records of patients undergoing HPB surgery from July 2012 to January 2017. An analysis was done of the demographic data, frequent diagnoses, fluid therapy, need for transfusions, length of hospital stay, need for reintervention, and 30-day mortality. Two groups were identified: group A (July 2012-December 2014) and group B (January 2015-January 2017) in which fast recovery protocols were implemented. Results: A total of 364 patients were included, 145 in group A and 219 in group B. The most frequent diagnoses were pancreatic cancer, liver metastasis, cholangiocarcinoma, and bile duct injury. Bleeding was less than 600 mL (OR = 12,88, CI 95%(5,3131,23)), the transfusion requirements dropped (OR=0.16; 95% CI: 0.068-0.418), and fluid therapy was below 5000 mL in group B (OR = 4.23; 95% CI: 1.76-10.11). Length of hospital stay was 3 days (interquartile range 2-5; p<0.001), and mortality at 30 days was lower in group B (p = 0.012). Conclusion: The implementation of fast recovery protocols showed a decrease in intraoperative bleeding, intravenous fluids therapy, length of hospital stay, and 30-day mortality.

Resumen Objetivos: Evaluar diferentes tratamientos de preservación de especímenes Anopheles albimanus para conocer su utilidad para conservar la cantidad y calidad del ADN que permita su análisis en estudios moleculares posteriores. Materiales y métodos: Se realizó un estudio comparativo experimental con tres bloques de tratamientos de preservación: sílica gel, etanol y congelación; los dos últimos bloques se dividieron en dos niveles cada uno: etanol absoluto, etanol al 70% y congelación a -20°C, congelación a -80°C respectivamente. El bloque control estuvo conformado por especímenes frescos sin tratamiento de preservación. Se extrajo el ADN de cada espécimen, se cuantificó por espectrofotometría y se amplifico el espaciador interno transcrito 2 (ITS2) mediante PCR. Se realizó un análisis comparativo entre bloques de tratamiento usando la frecuencia de amplificación de ITS2. Resultados: Se obtuvo la amplificación de ITS2 de todos los especímenes sin preservación previa, del 60% de los preservados en sílica gel y del 20% de los preservados en congelación a -80°C y en etanol al 70%. Se halló diferencia estadísticamente significativa (p<0,05) entre las proporciones de amplificación observadas. No se obtuvo amplificación de los especímenes preservados en congelación a -20°C y no se observó una correlación por regresión logística (p>0,05) entre el índice DO260/DO280 y la concentración de ADN de los especímenes que presentaron amplificación de ITS2. Conclusiones: Los datos sugieren que la conservación en sílica gel o la congelación que se vayan a -80°C pueden ser las mejores condiciones para la preservación de especímenes Anopheles a utilizar en estudios moleculares posteriores.
Abstract Introduction: Various methodologies have been reported for long term specimen preservation, which protect the DNA from degradation allowing its posterior analysis in molecular studies. However, the effectiveness of the preservation methods may vary among insect groups; therefore, it is convenient to determine the preservation method to be used with a particular group before performing molecular studies with a large number of specimens. Objetives: An experimental comparative study was conducted to evaluate different preservation treatments for Anopheles albimanus, to know their utility in conserving the quantity and quality of DNA to be used in subsequent molecular studies. Methods: DNA was extracted from each specimen, it was then quantified by spectrophotometer and the Internal Transcribed Spacer 2 (ITS2) was amplified by PCR. Results: ITS2 amplification was obtained in all specimens without previous preservation, in 60% of those preserved in sílica gel and in 20% of those preserved at -80°C and in 70% ethanol. A significant difference (p<0.05) was found between amplification proportions. Amplification was not obtained in specimens preserved frozen at -20°C and not correlation by logistic regression was observed between the DO260/DO280 index and DNA concentration of specimens presenting ITS2 amplification. Conclusions: The data suggest that keeping specimens in silica gel or frozen at -80°C may be the best conditions to preserve Anopheles specimens for subsequent molecular studies.
