ABSTRACT

INTRODUCTION: Currently there is little information in Latin America on the clinical outcome and manometric evolution of patients with Achalasia undergoing peroral endoscopic myotomy (POEM). PRIMARY OUTCOME: Evaluate the manometric and clinical changes in adult patients with achalasia after peroral endoscopic myotomy at a referral center in Bogotá, Colombia. METHODS: Observational, analytical, longitudinal study. Adult patients with achalasia according to the Chicago 4.0 criteria were included. Sociodemographic, clinical and manometric variables were described. To compare the pre- and post-surgical variables, the Student's or Wilcoxon's t test was used for the quantitative variables according to their normality, and McNemar's chi-square for the qualitative variables. RESULTS: 29 patients were included, 55.17% (n=16) women, with a mean age at the time of surgery of 48.2 years (±11.33). The mean post-procedure evaluation time was 1.88±0.81 years. After the procedure, there was a significant decrease in the proportion of patients with weight loss (37.93% vs 21.43% p 0.0063), chest pain (48.28% vs 21.43, p 0.0225) and the median Eckardt score (8 (IQR 8 -9) vs 2(IQR 1-2), p <0.0001). In addition, in fourteen patients with post-surgical manometry, significant differences were found between IRP values (23.05±14.83mmHg vs 7.69±6.06mmHg, p 0.026) and in the mean lower esophageal sphincter tone (9.63±7.2mmHg vs 28.8±18.60mmHg, p 0.0238). CONCLUSION: Peroral endoscopic myotomy has a positive impact on the improvement of symptoms and of some manometric variables (IRP and LES tone) in patients with achalasia.

ABSTRACT

High-resolution manometry (HRM) is a diagnostic tool for surgeons, gastroenterologists and other healthcare professionals to evaluate esophageal physiology. The Chicago Classification (CC) system is based on a consensus of worldwide experts to minimize ambiguity in HRM data acquisition and diagnosis of esophageal motility disorders. The most updated version, CCv4.0, was published in 2021; however, it does not provide step-by-step guidelines (i.e., for beginners) on how to assess the most important HRM metrics. This paper aims to summarize the basic guidelines for conducting a high-quality HRM study including data acquisition and interpretation, based on CCv4.0, using Manoview ESO analysis software, version 3.3 (Medtronic, Minneapolis, MN).

ABSTRACT

ABSTRACT After bariatric surgery one of the most common complications is dysphagia. The etiology of this disease has not been fully elucidated but it is known that it may be due to structural changes due to surgery. This case describes a 65-year-old female with early and severe onset of dysphagia following laparoscopic sleeve gastrectomy. The patient's final diagnosis was postobesity surgery esophageal dysfunction and laparoscopic proximal gastrectomy with esophagojejunal Roux-en-Y anastomosis was performed. Physicians should be aware of this condition in order to offer early diagnosis and treatment.


RESUMEN Después de una cirugía bariátrica una de las complicaciones más comunes es la disfagia. La etiología de esta enfermedad no ha sido completamente dilucidada, pero se sabe que puede deberse a cambios estructurales debidos a la cirugía. En este reporte se describe el caso de una mujer de 65 años con disfagia severa de aparición temprana después de una en manga gástrica laparoscópica. El diagnóstico final del paciente fue de una disfunción esofágica posterior a una cirugía de obesidad y se planteó como manejo una gastrectomía proximal laparoscópica con anastomosis esofagoyeyunal en Y de Roux. Hay que tener en cuenta las complicaciones a corto y largo plazo que se pueden presentar luego de cirugías de obesidad para poder realizar un diagnóstico temprano y poder ofrecer un tratamiento adecuado.

ABSTRACT

A Retículo Peritonite Traumática está diretamente ligada à ingestão de objetos metálicos perfuro cortantes, como pregos e pedaços de arame, que podem penetrar ou perfurar a parede do retículo. Embora a ocorrência de corpos estranhos de alumínio seja rara, outros elementos, como fios de pneus usados para fixar lonas em silagens e até cerdas de arame de escovas utilizadas em pequenos aeroportos, têm sido registrados como causas dessa afecção. A ingestão desses objetos pode resultar em lesões no retículo, desencadeando episódios de retículo peritonite traumática e suas sequelas, como pericardite traumática, inflamação do fígado, abscessos no baço e muito mais. Os sinais clínicos podem variar, mas incluem comportamento anormal, motilidade reduzida do rúmen, fezes mal digeridas, febre e sinais de dor. O diagnóstico baseia-se na avaliação dos sinais clínicos do animal, juntamente com exames complementares, como hemograma, bioquímico, ultrassom e radiografia. É importante considerar as alterações hematológicas, como leucocitose e hiperfibrinogenemia, como indicadores-chave desta afecção. O diagnóstico também envolve testes de dor ao corpo estranho. O tratamento pode ser conservativo ou cirúrgico. A abordagem conservativa envolve a administração de antibióticos, anti-inflamatórios e soluções intravenosas, além do tratamento de deficiências nutricionais subjacentes. A opção cirúrgica exige a remoção do corpo estranho do retículo, seguida de cuidados pós-operatórios.


Traumatic Reticulum Peritonitis this directly linked to the ingestion of sharp metallic objects, such as nails and pieces of wire, which can penetrate or pierce the wall of the reticulum. Although the occurrence of aluminum foreign bodies is rare, other elements, such as tire wires used to attach tarpaulins to silage and even wire bristles from brushes used in small airports, have been recorded as causes of this condition. Ingestion of these objects can result in damage to the reticulum, triggering episodes of traumatic reticulum peritonitis and its sequelae, such as traumatic pericarditis, liver inflammation, spleen abscesses and more. Clinical signs may vary but include abnormal behavior, reduced rumen motility, poorly digested feces, fever and signs of pain. The diagnosis is based on the evaluation of the animal's clinical signs, together with complementary tests, such as blood count, biochemistry, ultrasound and radiography. It is important to consider hematological changes, such as leukocytosis and hyperfibrinogenemia, as key indicators of this condition. Diagnosis also involves foreign body pain testing. Treatment can be conservative or surgical. The conservative approach involves administering antibiotics, anti-inflammatories and intravenous solutions, in addition to treating underlying nutritional deficiencies. The surgical option requires removal of the foreign body from the reticulum, followed by post-operative care.

Es importante considerar los cambios hematológicos, como la leucocitosis y la hiperfibrinogenemia, como indicadores clave de esta afección. El diagnóstico también implica la prueba del dolor por cuerpo extraño. El tratamiento puede ser conservador o quirúrgico. El enfoque conservador implica la administración de antibióticos, antiinflamatorios y soluciones intravenosas, además de tratar las deficiencias nutricionales subyacentes. La opción quirúrgica requiere la extracción del cuerpo extraño del retículo, seguida de cuidados postoperatorios.

ABSTRACT

Obesity is a very common pathology worldwide. Among the management alternatives are glucagon-like peptide-1 (GLP-1) analogues, a hormone secreted mainly by the intestine. Apart from its effects as an incretin, effects on gastrointestinal motility have been described, which seem to be fundamental for its effect on obesity, but also the cause of its most frequent potential adverse effects. There is discussion regarding the large number of case reports in relation to the retention of gastric contents at the time of endoscopy. There is currently insufficient evidence to state categorically that they produce a significant change in gastric emptying. Nevertheless, it is recommended to inquire about the use of these drugs before endoscopic procedures that require sedation and, in the presence of symptoms, to suggest changes in the preparation


La obesidad es una patología muy frecuente a nivel global. Dentro de las alternativas del manejo están los análogos del péptido 1 similar al glucagón (GLP-1), hormona secretada principalmente por el intestino. Aparte de sus efec- tos como incretina, se han descrito efectos sobre la motilidad gastrointestinal, los que parecen ser fundamentales para su efecto sobre la obesidad, pero también los causales de sus potenciales efectos adversos más frecuentes. Existe discusión en relación con la gran cantidad de reportes de casos en relación con la retención de contenido gástrico al momento de una endoscopia. Actualmente no existe evidencia suficiente para afirmar categóricamente que producen un cambio significativo en el vaciamiento gástrico. No obstante, se recomienda indagar sobre el uso de estos fármacos antes de procedimientos endoscópicos que requieran sedación y, ante la presencia de síntomas, sugerir cambios en la preparación.

ABSTRACT

Gastroesophageal reflux disease (GERD) is a complex entity and one of the most frequents in general population. Association of GERD with obesity is clearly defined from an epidemiological point of view, where up to 40% of patients with overweight and obesity present reflux. Most of the risk factors associated to GERD are shared and especially frequent in patients with obesity. The pathophysiology that explain this correlation is complex and multifactorial, and includes both aspects related to physiology of motility, and anatomic changes. The malfunction of the lower esophageal sphincter, the greater transdiaphragmatic pressure gradient, pathological accumulation of fat and the high rate of hiatal hernia that comes with overweight will be the main factors that explain this correlation. Other factor like pathological eating habits or obesity related diseases have also an important role. In summary, it is the sum of the factors more than just one of them what would explain the pathophysiology of GERD in obese population.

ABSTRACT

Sleeve gastrectomy (SG) is the most common bariatric surgery worldwide and has shown to cause de novo or worsen symptoms of gastroesophageal reflux disease (GERD). Esophageal motility and physiology studies are mandatory in bariatric and foregut centers. The predisposing factors in post-SG patients are disruption of His angle, resection of gastric fold and gastric fundus, increased gastric pressure, resection of the gastric antrum, cutting of the sling fibers and pyloric spasm. There are symptomatic complications due to sleeve morphology as torsion, incisura angularis stenosis, kinking and dilated fundus. In this article, we present recommendations, surgical technique and patient selection flow diagram for SG and avoid de novo or worsening GERD.

ABSTRACT

SUMMARY: This study aimed at clarifying the impact of long-term prenatal and postnatal exposure to exogenous progesterone on sperm production and function, relative sex organs weights, and the levels of the relevant hormones in rats. Sixty male Wistar rats were included and classified into three groups (n=20 in each). A test I group had mature rats born to dams treated with progesterone prenatally. A test II group included rats exposed to progesterone during prenatal as well as postnatal periods, and a control group had rats treated with a placebo (olive oil). The test groups revealed a significant reduction in sperm count, motility, and viability with higher abnormal forms than the control group (P< 0.05). Similarly, the test groups revealed significantly lower serum testosterone and higher FSH and LH levels (P< 0.001). Interestingly, the test II group showed pronounced sperm abnormalities, an alarming decrease in sperm viability and motility, and a significant accretion in the relative testicular weight compared to the test I group (p <0.001). Long-term (prenatal and early postnatal) treatment with synthetic progesterone hurts sperm quantity and quality, adversely affecting future male fertility.


Este estudio tuvo como objetivo aclarar el impacto de la exposición prenatal y posnatal a largo plazo a la progesterona exógena en la producción y función de los espermatozoides, el peso relativo de los órganos sexuales y los niveles de las hormonas relevantes en ratas. Sesenta ratas macho Wistar fueron incluidas y clasificadas en tres grupos (n=20 en cada uno). Un grupo de prueba I tenía ratas maduras nacidas de madres tratadas con progesterona prenatalmente. Un grupo de prueba II incluyó ratas expuestas a progesterona durante los períodos prenatal y posnatal, y un grupo de control tenía ratas tratadas con un placebo (aceite de oliva). Los grupos de prueba revelaron una reducción significativa en el recuento, la motilidad y la viabilidad de los espermatozoides con formas anormales más altas que el grupo de control (P < 0,05). De manera similar, los grupos de prueba revelaron niveles significativamente más bajos de testosterona sérica y niveles más altos de FSH y LH (P < 0.001). Curiosamente, el grupo de prueba II mostró anormalidades espermáticas pronunciadas, una disminución alarmante en la viabilidad y motilidad de los espermatozoides y una acumulación significativa en el peso testicular relativo en comparación con el grupo de prueba I (p <0.001). El tratamiento a largo plazo (prenatal y posnatal temprano) con progesterona sintética daña la cantidad y la calidad del esperma, lo que afecta negativamente la futura fertilidad masculina.

ABSTRACT

Introduction: Sperm motility is a crucial factor in male infertility and it depends on mitochondrial tail movements. Photobiomodulation light therapy allows the cells to produce their energy through activation of the mitochondria. The aim of the present study was to examine the impact of photobiomodulation on sperm motility in astenozoospermic individuals. Materials and methods: Following semen analyses of 20 astenozoospermic individuals, collected semen samples were centrifuged. Pellet was obtained and homogenized through mixing with culture media in 1:1 ratio. Each semen samples were divided into 3 groups. In the first group, control samples were not exposed to laser irradiation. The Group 2 and Group 3 were exposed to 650nm wavelength of photobiomodulation from 10cm distance in dark environment via a 36cm2 aperture sizer with 200mW output power for 30 and 60min duration, respectively. Sperm motilities were evaluated and chromatin condensation of sperms was determined. Results: Sperm motilities were significantly increased in photobiomodulation groups compared with the controls. Sperm motilities tended to be different between the 30 and 60min red light exposure groups; however, it was not statistically significant. When the motility grades were compared, no significant difference was observed in non-progressive motility sperms. While immotile sperms decreased significantly in the photobiomodulation groups compared to the control group, progressive sperms increased. (AU)


Introducción: La motilidad espermática es un factor crucial en la infertilidad masculina y depende de los movimientos de la cola mitocondrial. La fototerapia de fotobiomodulación permite que las células produzcan su energía a través de la activación de las mitocondrias. El objetivo del presente estudio fue examinar el impacto de la fotobiomodulación en la motilidad de los espermatozoides en individuos astenozoospérmicos. Materiales y métodos: Luego de los análisis de semen de 20 individuos astenozoospérmicos, se centrifugaron las muestras de semen recolectadas. Se obtuvo el sedimento y se homogeneizó mezclándolo con medios de cultivo en una proporción de 1:1. Cada muestra de semen se dividió en 3 grupos. En el primer grupo, las muestras de control no se expusieron a la irradiación láser. El grupo 2 y el grupo 3 fueron expuestos a una longitud de onda de 650nm de fotobiomodulación desde una distancia de 10cm en un ambiente oscuro a través de un medidor de apertura de 36cm2 con una potencia de salida de 200mW durante 30 y 60min de duración, respectivamente. Se evaluaron las motilidades de los espermatozoides y se determinó el tamaño de la cromatina de los espermatozoides. Resultados: La motilidad de los espermatozoides aumentó significativamente en los grupos de fotobiomodulación en comparación con los controles. La motilidad de los espermatozoides tendió a ser diferente entre los grupos de exposición a la luz roja de 30 y 60min; sin embargo, no fue estadísticamente significativo. Cuando se compararon los grados de motilidad, no se observaron diferencias significativas en los espermatozoides de motilidad no progresiva. Mientras que los espermatozoides inmóviles disminuyeron significativamente en los grupos de fotobiomodulación en comparación con el grupo de control, los espermatozoides progresivos aumentaron.

ABSTRACT

Introduction: Limited information is available regarding the clinical and manometric characteristics of different subtypes of achalasia. This study aims to describe these characteristics in patients treated at a prominent hospital in Colombia. Methods: This descriptive observational study included patients diagnosed with achalasia using high-resolution esophageal manometry at Hospital Universitario San Ignacio in Bogotá, Colombia, between 2016 and 2020. We documented the clinical manifestations, manometric findings, treatment approaches, and response to treatment based on the subtype of achalasia. Results: A total of 87 patients were enrolled, with a median age of 51 years, and 56.4% of them were female. The majority had type II achalasia (78.1%), followed by type I (16%) and type III (5.7%). All patients presented with dysphagia, 40.2% experienced chest pain, and 27.6% had gastroesophageal reflux. The clinical parameters, including integrated relaxation pressure value (IRP; median: 24 mmHg, interquartile range [IQR]: 19-33), upper esophageal sphincter pressure (UES; median: 63 mmHg, IQR: 46-98), and lower esophageal sphincter pressure (LES; median: 34 mm Hg, IQR: 26-45), were similar across the different subtypes. Esophageal clearance was incomplete in all patients. Among the 35 patients who received intervention, Heller's myotomy was the most commonly employed procedure (68.5%), followed by esophageal dilation (28.6%). All patients experienced symptomatic improvement, with a median pre-treatment Eckardt score of 5 (IQR: 5-6) and a post-treatment score of 1 (IQR: 1-2). Conclusions: Type II achalasia is the most prevalent subtype. The clinical and manometric findings, as well as treatment response, exhibit similarities among the different subtypes of achalasia. In Colombia, the outcomes of this condition align with those reported in other parts of the world.


Introducción: existe información limitada sobre las características clínicas y manométricas de los diferentes subtipos de acalasia. Este estudio describe dichas características en pacientes manejados en un hospital de referencia en Colombia. Método: estudio descriptivo observacional que incluye a pacientes con diagnóstico de acalasia por manometría esofágica de alta resolución manejados en el Hospital Universitario San Ignacio de Bogotá, Colombia, entre 2016 y 2020. Se describen las manifestaciones clínicas, hallazgos manométricos, tratamiento utilizado y respuesta al mismo según el subtipo de acalasia. Resultados: se incluyeron a 87 pacientes (mediana de edad: 51 años, 56,4% mujeres). La mayoría de tipo II (78,1%), seguido por tipo I (16%) y tipo III (5,7%). Todos presentaron disfagia, 40,2% dolor torácico y 27,6% reflujo gastroesofágico. La clínica y los valores del integral de presión de relajación (IRP; mediana: 24 mm Hg, rango intercuartílico [RIC]: 19-33), presión del esfínter esofágico superior (EES; mediana: 63 mm Hg, RIC: 46-98) y presión del esfínter esofágico inferior (EEI; mediana: 34 mm Hg, RIC: 26-45) fueron similares en los diferentes subtipos. El aclaramiento esofágico fue incompleto en todos los pacientes. Entre 35 pacientes que recibieron manejo intervencionista, la miotomía de Heller fue la intervención más utilizada (68,5%), seguido por la dilatación esofágica (28,6%). La totalidad de estos pacientes presentó una mejoría sintomática con la mediana de Eckardt pretratamiento de 5 (RIC: 5-6) y postratamiento de 1 (RIC: 1-2). Conclusiones: la acalasia tipo II es la más común. La clínica y los hallazgos manométricos y respuesta a tratamiento son similares entre los subtipos de acalasia. En Colombia, esta entidad se comporta de forma similar a lo reportado en otras partes del mundo.

ABSTRACT

Background/Aims: Absent contractility is considered a disorder of peristalsis. The literature about the etiology and clinical characteristics is scarce and the evidence on systemic diseases associated with this esophageal disorder is limited. Therefore, we aimed to determine the etiology of absent contractility in our population using the clinical algorithm recently described in the literature. Methods: We conducted a retrospective, descriptive study at a single tertiary hospital of all patients diagnosed of absent contractility between May 2018 and February 2020. Data on demographic characteristics, medication, comorbidities, and laboratory and paraclinical tests were recorded from clinical records. Results: A total of 72 patients with absent contractility were included for analysis. There was a predominance of female sex (n=43, 59.7%), with a mean age of 55.4 (±15.0) years. We identified a systemic disorder associated with absent contractility in 64 (88.9%) patients. From these, 31 (43.1%) patients were diagnosed with a systemic autoimmune disease, 26 (36.1%) patients were considered to have absent contractility secondary to pathological exposure to acid-reflux and 15 (20.8%) patients were diagnosed with other non-autoimmune systemic disorders. In the remaining eight (11.1%) patients, there were no underlying systemic disorders that could justify the diagnosis of absent contractility. Conclusions: A systematic approach to search for an underlying cause in patients diagnosed with absent contractility is warranted. Up to 90% of patients with absent contractility have a systemic disorder associated with this condition.(AU)


Antecedentes: La contractilidad ausente se considera un trastorno de la peristalsis esofágica. La literatura que existe sobre la etiología y las características clínicas es escasa y la evidencia sobre enfermedades sistémicas asociadas a este trastorno esofágico es limitada. Nuestro objetivo fue determinar la etiología de la contractilidad ausente en nuestra población utilizando el algoritmo clínico recientemente descrito en la literatura. Métodos: Se realizó un estudio descriptivo retrospectivo en un hospital terciario de todos los pacientes diagnosticados de ausencia de contractilidad entre mayo de 2018 y febrero de 2020. Se recogieron datos de características demográficas, medicación, comorbilidades y pruebas de laboratorio y estudios paraclínicos. Resultados: Se incluyeron para el análisis un total de 72 pacientes con ausencia de contractilidad. Predominó el sexo femenino (n=43, 59,7%), con una edad media de 55,4 (±15,0) años. Identificamos un trastorno sistémico asociado con la ausencia de contractilidad en 64 (88,9%) pacientes. De estos 31 (43,1%) pacientes fueron diagnosticados de una enfermedad autoinmune sistémica, 26 (36,1%) pacientes se consideraron con ausencia de contractilidad secundaria a exposición patológica al reflujo ácido y 15 (20,8%) fueron diagnosticados con otras enfermedades no autoinmunes sistémicas. En los 8 pacientes restantes (11,1%) no hubo trastornos sistémicos subyacentes que pudieran justificar el diagnóstico de contractilidad ausente. Conclusiones: Un enfoque sistemático está justificado para investigar una causa subyacente en pacientes diagnosticados de contractilidad ausente. Hasta el 90% de los pacientes con contractilidad ausente tienen un trastorno sistémico asociado con esta afectación de la motilidad esofágica.(AU)

ABSTRACT

Abstract Background: In artificial insemination, chicken egg yolk is added to bovine semen to protect it during the cryopreservation process, although it contains substances that can affect the microbiological quality and metabolism of sperm. Objective: To evaluate post-thaw quality of bovine cryopreserved semen added with centrifuged and non-centrifuged egg yolk, low-density lipoproteins (LDL), and trehalose (T). Methods: Ten ejaculates from five bulls were cryopreserved under the treatments T1: pure egg yolk (PEY) at 20% v/v, T2: centrifuged egg yolk (CEY) at 20% v/v, T3: LDL at 8% v/v, T4: T at 100 mM, and T5: T at 100 mM plus LDL at 8% v/v (TLDL). Spermatic motility and kinetics, functional membrane integrity (FMI), structural membrane integrity (SMI), sperm vitality (SV) and abnormal morphology (AM) were assessed using the Sperm Class Analyzer (SCA®) system, hypoosmotic test (HOST), SYBR/PI probes, and eosin-nigrosin staining, respectively. A completely randomized design was used. Normal distribution of the variables was validated through the Kolmogórov- Smirnov test. A generalized linear model was used to determine sources of variation. Means were compared using the Tukey test. Results: Inclusion of CEY or LDL had a similar effect on sperm protection, and were superior for motility, kinetics and membrane integrity compared to the other treatments (p<0.05). CEY was superior for progressive motility (p<0.05). The cryoprotective action of LDL was similar to TLDL for motility and kinetics, SMI, SV, and AM (p<0.05). Inclusion of PEY and T resulted in the lowest semen quality (p<0.05). The use of T resulted in a reduction in FMI and SMI (p<0.05). No differences in AM between treatments were found (p>0.05). Conclusions: Egg yolk can be replaced by centrifuged egg yolk or low-density lipoproteins in the freezing extender used for bovine semen used in artificial insemination.


Resumen Antecedentes: la yema de huevo de gallina se agrega al semen bovino usado en inseminación artificial para protegerlo durante el proceso de criopreservación, aunque ésta tiene sustancias que pueden afectar el metabolismo espermatico y la calidad microbiológica del semen. Objetivo: evaluar la calidad post-descongelación del semen bovino criopreservado agregado con yema de huevo centrifugada y no centrifugada, lipoproteínas de baja densidad (LDL) y trehalosa (T). Métodos: diez eyaculados de cinco toros se criopreservaron bajo los tratamientos, T1: yema de huevo pura (PEY) al 20% v/v, T2: yema de huevo centrifugada (CEY) al 20% v/v, T3: LDL al 8% v/v, T4: T a 100 mM, y T5: T a 100 mM más LDL al 8% v/v (TLDL). La movilidad y la cinética espermática, la integridad funcional de la membrana (FMI), la integridad estructural de la membrana (SMI), la vitalidad espermática (SV) y la morfología anormal (AM), se determinaron mediante el sistema Sperm Class Analyzer (SCA®), la prueba hipoosmótica (HOST), las sondas SYBR/PI y la tinción con eosina-nigrosina, respectivamente. Se utilizó un diseño completamente al azar. La normalidad de las variables se validó mediante la prueba de Kolmogórov-Smirnov. Se utilizó un modelo lineal generalizado para determinar las fuentes de variación. Las medias de los tratamientos se compararon mediante la prueba de Tukey. Resultados: CEY y LDL tuvieron un efecto similar en la protección de los espermatozoides, siendo superiores a los demás tratamientos respecto a movilidad, cinética e integridad de la membrana (p<0,05). CEY fue superior para la movilidad progresiva (p<0,05). La acción crioprotectora de LDL fue similar a TLDL para movilidad y cinética, SMI, AM y SV (p<0,05). PEY y T resultaron en la más baja calidad seminal (p<0,05). El uso de T redujo la FMI y la SMI (p<0,05). No se encontraron diferencias en AM entre los tratamientos (p>0,05). Conclusiones: la yema de huevo puede reemplazarse por yema de huevo centrifugada o por lipoproteinas de baja densidad en el diluyente de congelación usado para semen bovino destinado a inseminacion artificial.

ABSTRACT

Introducción: La esofagitis eosinofílica es una enfermedad emergente, caracterizada por infiltración del esófago por leucocitos eosinófilos. Sus principales síntomas son la disfagia y las frecuentes impactaciones de alimento en el esófago. Actualmente existen evidencias científicas que reconocen la enfermedad como causa posible de evolución no favorable en pacientes después de miotomía de Héller. Objetivo: Describir las evidencias biomoleculares que asocian la esofagitis eosinofílica y la acalasia esofágica. Métodos: Se realizó una revisión sistemática y crítica de las evidencias sobre los mecanismos biomoleculares asociados a la esofagitis eosinofílica y la acalasia esofágica. Se consultaron artículos publicados entre 2015 y 2020 e indexados en las bases de datos PubMed, SciELO, LILACS y Scopus. Análisis e integración de la información: Se discute sobre cuestiones medulares que han sido publicadas recientemente respecto al tema en cuestión. ¿Pueden coexistir la esofagitis eosinofílica y la acalasia esofágica? ¿Influye la esofagitis eosinofílica en el resultado del tratamiento de la acalasia esofágica? ¿Qué investigaciones serían necesarias para establecer la relación entre las dos enfermedades? Conclusiones: Los mecanismos celulares y biomoleculares desencadenados por la infiltración eosinofílica contextualizan la diferencia etiológica y fisiopatológica de la esofagitis eosinofílica y la acalasia esofágica, lo cual sustenta la evolución desfavorable posmiotomía de los pacientes y motiva la realización de estudios prospectivos y controlados con el fin de ofrecer una mejor calidad de vida(AU)


Introduction: Eosinophilic esophagitis is an emerging disease characterized by infiltration of the esophagus by eosinophilic leukocytes. Its main symptoms are dysphagia and frequent food impaction in the esophagus. Scientific evidence is now available that recognizes the disease as the possible cause of unfavorable evolution in patients undergoing Heller myotomy. Objective: Describe the biomolecular evidence associating eosinophilic esophagitis to esophageal achalasia. Methods: A systematic critical review was conducted of the evidence about biomolecular mechanisms associated to eosinophilic esophagitis and esophageal achalasia. The articles consulted were published in the databases PubMed, SciELO, LILACS and Scopus from 2015 to 2020. Data analysis and integration: A discussion is provided about crucial questions published recently concerning the study topic: Can eosinophilic esophagitis and esophageal achalasia coexist? Does eosinophilic esophagitis influence the result of esophageal achalasia treatment? What studies are required to establish the relationship between the two conditions? Conclusions: The cellular and biomolecular mechanisms triggered by eosonophilic infiltration contextualize the etiological and pathophysiological difference between eosinophilic esophagitis and esophageal achalasia. This explains the unfavorable post-myotomy evolution of patients and encourages the conduct of prospective controlled studies aimed at enhancing quality of life(AU)

ABSTRACT

Introducción y objetivos La sensación de inestabilidad es un síntoma frecuente tras un latigazo cervical (LC), existiendo alteraciones objetivas del control postural en fases crónicas. El objetivo fundamental de nuestro estudio fue evaluar las alteraciones objetivas del control postural, así como la presencia o ausencia de alteraciones oculomotoras en las fases agudas tras un LC. Material y métodos Se realizó un estudio posturográfico mediante sistema NedSVE/IBV y una valoración oculomotora en una muestra de 44 sujetos afectos de LC en las primeras 24h tras el accidente. Resultados Más de la mitad de los pacientes estudiados presentaron una valoración global por debajo de la normalidad. El patrón sensorial predominante fue el denominado patrón vestibular. Los parámetros fundamentales del test de Romberg (desplazamiento total, área de barrido, velocidad media, desplazamientos anteroposterior y mediolateral y fuerza anteroposterior) aumentaron siguiendo la secuencia Romberg ojos abiertos, Romberg gomaespuma ojos abiertos, Romberg ojos cerrados y Romberg gomaespuma ojos cerrados. En cuanto a la comparación con la normalidad y utilizando los valores de referencia del Instituto de Biomecánica de Valencia, los datos de los pacientes de LC muestran diferencias significativas en todos los parámetros analizados, salvo en la valoración de la marcha y el control rítmico direccional mediolateral. Conclusiones Nuestros datos confirman que los pacientes en fase aguda del LC presentan un peor control postural desde las primeras horas tras el accidente. Los resultados evidencian que los pacientes con LC tienen una mayor dependencia visual. Solo una minoría de los pacientes presentan alteraciones oculomotoras durante la exploración temprana (AU)


Introduction and objectives Instability is a frequent symptom after whiplash (WL) with alterations in postural control in chronic phases. The main objective of our study was to evaluate if there were objective alterations in postural control in the acute phases after a WL, as well as to determine the presence or absence of oculomotor alterations in early phases. Material and methods A posturographic study was carried out using the NedSVE/IBV system, as well as an oculomotor assessment, in a sample of 44 patients with WL in the first 24h after the accident. Results More than half of the patients had a global assessment below normal. The predominant sensory pattern was vestibular. The main parameters of the Romberg test (total displacement, swept area, average speed, anteroposterior and mediolateral displacement and anteroposterior force) increased following the sequence Romberg open eyes, Romberg foam rubber open eyes, Romberg closed eyes, and Romberg foam rubber closed eyes. Concerning the comparison with normality and using the reference values of the Institute of Biomechanics of Valencia, the data from the WL patients showed significant differences in all the parameters analysed, except for gait assessment and the mediolateral directional rhythmic control. Conclusions Our data confirm that patients in the acute phase of WL have worse postural control than non-injured persons. The results suggest that patients with WL have greater visual dependence. Only a minority of patients had oculomotor abnormalities during early examination (AU)

ABSTRACT

Introduction: adults in intensive care commonly receive enteral nutrition (EN). Data describing the conditions associated with EN in critically ill patients are limited. Objective: to describe the incidence of gastrointestinal disorders and to identify conditions associated with the use of EN. Methods: a prospective cohort, single-center study of critically ill adults. The patients were followed daily for the first 10 days of hospitalization in the intensive care unit (ICU) or until ICU discharge or death. Clinical, nutritional variables and gastrointestinal disorders were compared between patients who did and did not receive EN. Univariate and multivariate regression identified the conditions associated with EN with the proposed variables. Results: of the 157 included adults, 62 % received EN. The EN group had higher APACHE II (23.6 ± 7.6 vs. 15 ± 7.2, p < 0.001) and SOFA scores on the day of ICU admission [7 (5-10.5) vs. 4 (2-6); p < 0.001], and higher ICU mortality (32 % vs. 10 %, p = 0.002). Diarrhea and need for gastric decompression were more frequent in the EN group (39.7 % vs. 11.7 %, p < 0.001 and 34 % vs. 13.3 %, p = 0.004, respectively). The multivariate analysis showed that neurological deficit (OR: 16.7 [95 % CI: 5.9-46.9]; p < 0.001), previous enteral tube feeding (OR: 45.1 [95 % CI: 5.3-380]; p < 0.001), and SOFA score on the day of ICU admission (OR: 1.2 [95 % CI: 1.01-1.3]; p = 0.03) were associated with EN. Conclusions: conditions related to the severity of critically ill patients, such as higher SOFA scores, greater neurological deficit, and prior enteral tube feeding, were more commonly associated with EN. Diarrhea and need for gastric decompression were more frequent in patients who received EN. (AU)


Introducción: los adultos en cuidados intensivos comúnmente reciben nutrición enteral (NE). Los datos que describen las condiciones asociadas con la NE en pacientes críticos son limitados. Objetivo: describir la incidencia de trastornos gastrointestinales e identificar las condiciones asociadas con el uso de la NE. Métodos: estudio prospectivo de cohortes en un solo centro, de adultos en estado crítico. Se monitoreó a los pacientes diariamente en los primeros 10 días de hospitalización en la unidad de cuidados intensivos (UCI) o hasta el alta o la muerte en la UCI. Se compararon las variables y los trastornos gastrointestinales entre los pacientes que recibieron y no recibieron NE. La regresión univariada y multivariada identificó las condiciones asociadas con la NE con las variables propuestas. Resultados: de los 157 adultos incluidos, el 62 % recibieron NE. El grupo con NE tuvo puntuaciones APACHE II (23,6 ± 7,6 frente a 15 ± 7,2; p < 0,001) y SOFA más altas en el día de la admisión en la UCI [7 (5-10,5) frente a 4 (2-6); p < 0,001] y mayor mortalidad en la UCI (32 % vs. 10 %, p = 0,002). La diarrea y la necesidad de descompresión gástrica fueron más frecuentes en el grupo con NE (39,7 % vs. 11,7 %; p < 0,001 y 34 % vs. 13,3 %, p = 0,004, respectivamente). El análisis multivariado mostró que el déficit neurológico (OR: 16,7 [IC 95 %: 5,9-46,9]; p < 0,001), la alimentación anterior por sonda enteral (OR: 45,1 [IC 95 %: 5,3-380]; p < 0,001) y la puntuación SOFA en el día de la admisión en la UCI (OR: 1,2 [IC 95 %: 1,01-1,3]; p = 0,03) presentaban asociación con la NE. Conclusión: las condiciones relacionadas con la gravedad de los pacientes críticos, como las puntuaciones SOFA más altas, el mayor déficit neurológico y la alimentación anterior por sonda enteral, se asociaron más con la NE. La diarrea y la necesidad de descompresión gástrica fueron más frecuentes en los pacientes que recibieron NE. (AU)

ABSTRACT

Resumen Introducción: La enfermedad por reflujo gastroesofágico (ERGE) refractaria puede conducir a complicaciones potenciales como la esofagitis persistente, estenosis esofágica, anillo de Schatzki y esófago de Barrett. Este estudio describe la motilidad en pacientes con ERGE refractaria y su relación con síntomas esofágicos. Método: Se realizó un estudio observacional analítico a partir de una cohorte retrospectiva en pacientes con diagnóstico de ERGE refractaria y síntomas esofágicos a quienes se les realizó manometría esofágica de alta resolución más impedanciometría. Se describen las características clínicas y demográficas, y la asociación entre los trastornos manométricos y los síntomas esofágicos. Resultados: Se incluyeron 133 pacientes (edad promedio: 54,1 ± 12,5 años). La pirosis y regurgitación (69,2 %) y la disfagia esofágica (13,5 %) fueron los síntomas más comunes. La motilidad normal (75,2 %), el aclaramiento completo del bolo (75,2 %) y la motilidad esofágica inefectiva (MEI) (18 %) fueron los hallazgos manométricos más frecuentes. La unión gastroesofágica tipos II y IIIb estuvieron presentes en el 35,3% y 33,8 % de los casos, respectivamente. La aperistalsis (3,8 %) y el esófago en martillo neumático (Jackhammer; 0,8 %) fueron infrecuentes. El aclaramiento incompleto del bolo se asoció con disfagia esofágica (p = 0,038) y a MEI (p = 0,008). Ningún síntoma esofágico se relacionó significativamente con trastornos de motilidad. Conclusiones: Los resultados de nuestro estudio sugieren que los trastornos de motilidad son infrecuentes en los pacientes con ERGE refractaria. Adicionalmente, sugieren que la presencia de alteraciones de motilidad esofágica no se relaciona con la presencia de síntomas esofágicos y, por tanto, que el tipo de síntoma presentado no permite predecir la existencia de dichos trastornos.


Abstract Introduction: Refractory gastroesophageal reflux disease (GERD) can lead to potential complications such as persistent esophagitis, esophageal stricture, Schatzki ring, and Barrett's esophagus. This study describes motility in patients with refractory GERD, and its association with esophageal symptoms. Materials and methods: An analytical observational study was carried out in a retrospective cohort of patients diagnosed with refractory GERD and esophageal symptoms who underwent high-resolution esophageal manometry and impedance testing. Clinical characteristics, demographics, and the association between motility disorders and esophageal symptoms are described. Results: 133 patients were included (mean age 54.1 ± 12.5 years). Heartburn and regurgitation (69.2%), and esophageal dysphagia (13.5%) were the most common symptoms. Normal motility (75.2%), complete bolus clearance (75.2%), and ineffective esophageal motility (IEM) (18%) were the most frequent manometric findings. Type II and IIIb gastroesophageal junction were observed in 35.3% and 33.8% of the cases, respectively. Esophageal aperistalsis (3.8%) and Jackhammer esophagus (0.8%) were rare findings. Incomplete bolus clearance was associated with esophageal dysphagia (p=0.038) and IEM (p=0.008). No esophageal symptoms were significantly related to motility disorders. Conclusions: The results of the present study suggest that motility disorders are rare in patients with refractory GERD. They also suggest that esophageal motility disorders are not associated with the presence of esophageal symptoms and, therefore, the type of symptom experienced does not allow predicting the existence of such disorders.

ABSTRACT

Resumen Mediante la distensión de un balón con líquido conductor, la sonda de imagen luminal funcional endoluminal (EndoFLIP) evalúa las propiedades biomecánicas como la distensibilidad, volumen, presión e inclusive diámetros de regiones esfinterianas como la unión gastroesofágica, píloro y ano. La mayor evidencia en la utilidad clínica de la EndoFLIP está en los trastornos de motilidad esofágica, principalmente para identificar acalasia cuando la manometría esofágica de alta resolución y otras imágenes no logran diagnosticarla e inclusive, mediante el programa de FLIP 2.0, caracteriza la acalasia en subtipos a partir de patrones de motilidad del esófago distal en respuesta a la distensión. Se ha demostrado recientemente que la EndoFLIP tiene un rol diagnóstico, pronóstico o terapéutico en otras patologías como la esofagitis eosinofílica, reflujo gastroesofágico, gastroparesia, durante la fundoplicatura y dilatación esofágica.


Abstract EndoFLIP evaluates biomechanical properties such as distensibility, volume, pressure, and even diameters of sphincter regions like the gastroesophageal junction, pylorus, and anus, by distending a balloon with a conductive medium. The best evidence of the clinical utility of EndoFLIP is observed in esophageal motility disorders, mainly when identifying achalasia when high-resolution esophageal manometry and other images fail to diagnose it. Even EndoFLIP 2.0 characterizes achalasia into subtypes based on distal esophageal motility patterns in response to distention. Recently, it has been shown that this system has a diagnostic, prognostic and/or therapeutic role in other diseases such as eosinophilic esophagitis, gastroesophageal reflux, and gastroparesis, and during fundoplication and esophageal dilation.

ABSTRACT

RESUMEN El sistema cannabinoide endógeno es un nuevo sistema de comunicación intercelular que constituye una pieza crucial en la regulación de la función intestinal. Se realizó una revisión bibliográfica con el objetivo de describir cómo el sistema cannabinoide endógeno modula la función intestinal. Se consultaron un total de 31 referencias bibliográficas entre libros, revistas, tesis doctorales y artículos en internet. Se encontró que los endocannabinoides son inmunomoduladores a nivel intestinal, que el sistema cannabinoide endógeno regula la composición de la microbiota intestinal y esta a su vez determina la concentración de los endocannabinoides, además tanto la secreción como la motilidad intestinal disminuyen por estimulación del sistema cannabinoide endógeno. Los receptores de cannabinoides, los endocannabinoides anandamida y 2-araquidonoilglirerol y las proteínas responsables de su síntesis y degradación están ampliamente distribuidos en el intestino en condiciones fisiológicas, aumentando su expresión en la enfermedad inflamatoria intestinal lo que le permite regular la función intestinal en ambas condiciones. El sistema cannabinoide endógeno tiene un enorme potencial terapéutico en la enfermedad inflamatoria intestinal debido a los efectos inmunosupresores, antiinflamatorios y analgésicos que posee.


ABSTRACT The endogenous cannabinoid system is a new intercellular communication system that constitutes a crucial piece in the regulation of intestinal function. A bibliographic review was carried out in order to describe how the endogenous cannabinoid system modulates intestinal function. A total of 31 bibliographic references were consulted between books, magazines, doctoral theses and articles on the internet. It was found that endocannabinoids are immunomodulatory at the intestinal level, that the endogenous cannabinoid system regulates the composition of the intestinal microbiota and this in turn determines the concentration of endocannabinoids, in addition both secretion and intestinal motility decrease by stimulation of the endogenous cannabinoid system. The cannabinoid receptors, the endocannabinoids anandamide and 2-arachidonoylglirerol, and the proteins responsible for their synthesis and degradation are widely distributed in the intestine under physiological conditions, increasing their expression in inflammatory bowel disease, which allows it to regulate intestinal function in both conditions. The endogenous cannabinoid system has enormous therapeutic potential in inflammatory bowel disease due to its immunosuppressive, anti-inflammatory and analgesic effects.


RESUMO O sistema canabinoide endógeno é umnovo sistema de comunicação intercelular que constitui uma peça crucial na regulação da função intestinal. Foi realizada uma revisão bibliográfica para descrever como o sistema canabinoide endógeno modula a função intestinal. Foram consultadas 31referências bibliográficas entre livros, revistas, teses de doutorado e artigosna internet. Verificou-se que os endocanabinoides são imunomoduladores em nível intestinal, que o sistema canabinoide endógeno regula a composição da microbiota intestinal e esta, por sua vez, determina a concentração de endocanabinoides, além da diminuição da secreção e da motilidade intestinal pela estimulação do sistema canabinoide endógeno. Os receptores canabinoides, os endocanabinoides anandamida e 2-araquidonoilglirerol e as proteínas responsáveis ​​por sua síntese e degradação estão amplamente distribuídos no intestino em condições fisiológicas, aumentando sua expressão em doenças inflamatórias intestinais que permitem regular a função intestinal em ambas as condições. O sistema canabinoide endógeno apresenta enorme potencial terapêutico na doença inflamatória intestinal devido aos seus efeitos imunossupressores, antiinflamatórios e analgésicos.
