Lymphoepithelioma-Like Gastric Carcinoma and Gastric Involvement of Chronic Lymphocytic Leukemia: Two Rare Identities Coexisting in One Patient.

Lymphoepithelioma-like gastric carcinoma (LELGC) constitutes 1-4% of all gastric carcinomas and gastrointestinal involvement in leukemia can be present in up to 25%, being more common in acute than chronic leukemia, affecting most frequently the stomach, ileum, and proximal colon. LELGC is usually associated with a better prognosis than other gastric carcinomas, generally presenting with low T and N stages. The reports of chronic lymphocytic leukemia (CLL) involving infiltration of the gastrointestinal tract are relatively rare in the literature, and the estimated incidence ranges from 5.7% to 25%. We present the case of a 77-year-old female, on surveillance by a known CLL that was diagnosed with gastric carcinoma on an esophagogastroduodenoscopy (EGD) performed for epigastric pain. A subtotal gastrectomy was performed and the surgical specimen revealed simultaneous involvement of the stomach by LELGC and CLL. To the best of our knowledge, this is the first reported case of a LELGC and CLL simultaneously involving the stomach.

Distal Pancreatectomy for Solid Pseudopapillary Tumor of the Pancreas: A Case Report.

Solid pseudopapillary tumor (SPT) of the pancreas is a rare tumor, sometimes asymptomatic, mainly affecting young females. It has a low malignant potential, and its complete surgical resection with free margins is the treatment of choice, offering an excellent prognosis. We present the case of a 43-year-old healthy female who was referred to the surgery department for a large abdominal mass found in the abdominal ultrasound. In the course of the study of this mass, an abdominal CT with fine needle aspiration (FNA) was performed, revealing a solid pseudopapillary tumor of the tail of the pancreas. A laparotomic distal pancreatectomy with total splenectomy was performed. A grade B pancreatic fistula occurred on the third postoperative day, and she was released on postoperative day 11. Histopathology study revealed a 10 cm solid pseudopapillary tumor of the pancreas, with cavities filled with hematic content and limited by a partially calcified capsule. SPT is a rare and indolent tumor. Prognosis is highly favorable after an adequate surgical resection, hence the importance of a precise preoperative diagnosis. Therefore, it is important to choose the most appropriate surgical strategy for each patient.

Transvaginal Resection of a Rectal Gastrointestinal Stromal Tumor: A Case Report.

Gastrointestinal stromal tumors (GISTs) are a type of mesenchymal tumors. They are rare in rectum. This location is a surgical challenge due to the high morbidity after aggressive surgeries. We present the case of an 81-year-old female with a high-grade GIST treated with transvaginal excision and adjunctive therapy with imatinib. The postoperative period was uneventful without anal dysfunction. Within the types of surgical treatment available, transvaginal excision is an acceptable procedure in lesions located in the rectovaginal region.

Hemoperitoneum secondary to mesenteric laceration after abdominal trauma - Case report.

Mesenteric laceration is an uncommon cause of hemoperitoneum, with nonspecific signs and symptoms and frequently is camouflaged by the signs of other traumatic lesions. There is a high risk to go unnoticed increasing morbidity and mortality. We report a case of a 43-year-old man, who was involved in a motorcycle accident, with thoraco-abdomino-pelvic trauma, but without evidence of intra-abdominal lesions on exams, with exception of hemoperitoneum. Due to hemodynamic instability, it was performed an exploratory laparotomy. Intraoperative findings were mesenteric lacerations affecting a small bowel segment. This case demonstrates that a high index of suspicion is necessary to diagnose and treat lesions like mesenteric laceration, not visible early on imaging but potentially fatal, with high risk of complications.

Molecular inference in the colonization of cattle in Ecuador.

The aim of the present paper was to evaluate genetic diversity within and among Ecuadorian bovine breeds using microsatellite markers. The genetic identity and the exotic influences from taurine or zebuine cosmopolitan breeds on Macabea, Loja, Santa Elena, Manabí and Isla de Puná breeds were evaluated. Twenty-eight microsatellite markers were tested across 254 individuals belonging to the five Ecuadorian populations to investigate intra and inter population genetic diversity levels. Nineteen markers in common with a set of 1595 samples of 35 previously typed breeds were used to determine the potential origin of Ecuadorian bovine breeds and to identify and quantify their genetic relationships. The findings of FIS > FST (0.0814 > 0.0499), even in the context of low but significant FST values, may be indicative of the intrapopulation origin of the variability of allelic frequencies across populations. Conclusively, the study of genetic distances and population structure suggested the origin of Ecuadorian populations may likely stem from Southern Spanish breeds, with no significant recent influence from cosmopolitan Taurine or Zebuine breeds. These findings may provide a solid basis for the demonstration of an Ecuadorian breeds identity in the framework of the genetic conservation of the American creole populations.

Evaluation of LoRa Technology in Flooding Prevention Scenarios.

Global climate change originates frequent floods that may cause severe damage, justifying the need for real-time remote monitoring and alerting systems. Several works deal with LoRa (Long Range) communications over land and in the presence of obstacles, but little is known about LoRa communication reliability over water, as it may happen in real flooding scenarios. One aspect that is known to influence the communication quality is the height at which nodes are placed. However, its impact in water environments is unknown. This is an important aspect that may influence the location of sensor nodes and the network topology. To fill this gap, we conducted several experiments using a real LoRa deployment to evaluate several features related to data communication. We considered two deployment scenarios corresponding to countryside and estuary environments. The nodes were placed at low heights, communicating, respectively, over the ground and over the water. Measurements for packet loss, received signal strength indicator (RSSI), signal-to-noise ratio (SNR) and round-trip time (RTT) were collected during a period of several weeks. Results for both scenarios are presented and compared in this paper. One important conclusion is that the communication distance and reliability are significantly affected by tides when the communication is done over the water and nodes are placed at low heights. Based on the RTT measurements and on the characteristics of the hardware, we also derive a battery lifetime estimation model that may be helpful for the definition of an adequate maintenance plan.

Genetic diversity evolution of a sheep breed reintroduced after extinction: Tracing back Christopher Columbus' first imported sheep.

New World's hair sheep breeds may genetically stem from West African introgression into established ecotypes of Spanish descent presumably extinct in the XIX Century. However, present Canary non-wooled breeds have presumably regressively resulted from the absorption of primitive individuals through Venezuelan descendants. We studied genetic diversity, structure, and evolution of the Canary hair sheep since its reintroduction in the 1950s. Demographic and genetic variability were evaluated using ENDOG (v4.8). Effective population size based on individual inbreeding rate was around one third higher than when based on individual coancestry rate. Nei's distances and equivalent subpopulations number indicated a highly-structured population. Although genetic diversity loss since the founder generations could be considered small, narrower pedigree bottlenecks could result from intraflock breeding policies and excessive contribution of few ancestors. Long generation intervals could be considered when reducing inbreeding. Wright's fixation statistics indicated slight interflock inbreeding. Pedigree completeness suggested genetic parameters were reliable, hence controlling inbreeding negative effects, could indeed, be crucial preserving these animal resources, consolidating the population in the archipelago after reintroduction.

Effect of Research Impact on Emerging Camel Husbandry, Welfare and Social-Related Awareness.

The lack of applied scientific research on camels, despite them being recognized as production animals, compels the reorganization of emerging camel breeding systems with the aim of achieving successful camel welfare management strategies all over the world. Relevant and properly-framed research widely impacts dissemination of scientific contents and drives public willingness to enhance ethically acceptable conditions for domestic animals. Consumer perception of this livestock industry will improve and high-quality products will be obtained. This paper draws on bibliometric indicators as promoting factors for camel-related research advances, tracing historical scientific publications indexed in ScienceDirect directory from 1880-2019. Camel as a species did not affect Journal Citation Reports (JCR) impact (p > 0.05) despite the journal, author number, corresponding author origin, discipline and publication year affecting it (p < 0.001). Countries with traditionally well-established camel farming are also responsible for the papers with the highest academic impact. However, camel research advances may have only locally and partially influenced welfare related laws, so intentional harming acts and basic needs neglect may persist in these species. A sustainable camel industry requires those involved in camel research to influence business stakeholders and animal welfare advocacies by highlighting the benefits of camel wellbeing promotion, co-innovation partnership establishment and urgent enhancement of policy reform.

Sensory Preference and Professional Profile Affinity Definition of Endangered Native Breed Eggs Compared to Commercial Laying Lineages' Eggs.

This study aimed to compare Utrerana native hen eggs' sensory properties to Leghorn Lohmann LSL-Classic lineage's commercial and ecological eggs through free-choice profiling. Second, affine and non-affine profiles were defined using the information provided by professionally-instructed panelists on six sets (sensory attributes, diet habits, production context awareness, product consciousness, cuisine applicability and panelist attributes) using nonlinear canonical correlation analysis. Sixty-four instructed professional panelists rated 96 eggs on 39 variables comprising the above-mentioned sets. Observers reported a significantly higher appreciation (p > 0.05) towards yolk color, odor, flavor, texture, overall score, and whole and on plate broken egg visual value when Utrerana eggs were compared to the rest of categories. Professional Profile A (PPA), or egg non-affine profile, consumed less eggs and provided lower scores to sensory attributes than Professional Profile B (PPB), or affine profile. Additionally, PPB accounted for higher knowledge about the Utrerana breed and provided greater importance to a product's ecological and autochthonous nature. PPA was generally characterized by women under 20 years old with no higher studies, while PPB comprised 21-40 years old men with secondary studies. In conclusion, defining professional profiles enables correctly approaching market needs to improve the profitability of Utrerana eggs, meeting professional demands and educating non-affine profiles.

Non-Parametrical Canonical Analysis of Quality-Related Characteristics of Eggs of Different Varieties of Native Hens Compared to Laying Lineage.

The aim of the present study is to characterize the productive capability of Utrerana and to compare the relationships among parameters determining the internal and external quality of the egg, through canonical correlation analysis. A flock of 68 Utrerana hens and a control group of Leghorn hens (n = 17) were housed individually to allow individual identification of eggs and for the assessment of egg quality characteristics. Almost all variables showed differences when both breeds were compared, except for white height, yolk diameter, yolkL* and yolk pH (p > 0.05). Only minor diameter, white height, yolkL*, yolka*, and shell weight reported significant differences between laying age groups. White height, yolk color, and almost all yolk color coordinates were significantly different (p < 0.05) for period and month. Egg and white weight reached highest significantly different levels for the fourth and fifth time that the hens laid an egg. External quality-related traits are better predictors of internal quality-related traits than vice versa, enabling the implementation of an effective noninvasive method for internal quality determination and egg classification aimed at suiting the needs of consumers.

Separability of motor imagery of the self from interpretation of motor intentions of others at the single trial level: an EEG study.

BACKGROUND: We aimed to investigate the separability of the neural correlates of 2 types of motor imagery, self and third person (actions owned by the participant himself vs. another individual). If possible this would allow for the development of BCI interfaces to train disorders of action and intention understanding beyond simple imitation, such as autism. METHODS: We used EEG recordings from 20 healthy participants, as well as electrocorticography (ECoG) in one, based on a virtual reality setup. To test feasibility of discrimination between each type of imagery at the single trial level, time-frequency and source analysis were performed and further assessed by data-driven statistical classification using Support Vector Machines. RESULTS: The main observed differences between self-other imagery conditions in topographic maps were found in Frontal and Parieto-Occipital regions, in agreement with the presence of 2 independent non µ related contributions in the low alpha frequency range. ECOG corroborated such separability. Source analysis also showed differences near the temporo-parietal junction and single-trial average classification accuracy between both types of motor imagery was 67 ± 1%, and raised above 70% when 3 trials were used. The single-trial classification accuracy was significantly above chance level for all the participants of this study (p < 0.02). CONCLUSIONS: The observed pattern of results show that Self and Third Person MI use distinct electrophysiological mechanisms detectable at the scalp (and ECOG) at the single trial level, with separable levels of involvement of the mirror neuron system in different regions. These observations provide a promising step to develop new BCI training/rehabilitation paradigms for patients with neurodevelopmental disorders of action understanding beyond simple imitation, such as autism, who would benefit from training and anticipation of the perceived intention of others as opposed to own intentions in social contexts.

Evaluación de algunos factores predictivos de Dehiscencia de sutura intestinal: experiencia de diez años / Evaluation of some predictive factors of dehiscence of intestinal suture ten years experience

La sutura intestinal se realiza con periodicidad en los servicios de cirugía general, pero es la dehiscencia de sutura la complicación mas temida por el cirujano que la realiza, debido a la alta morbilidad y letalidad que la acompaña y lo dificultoso de su manejo. Se realizo un estudio con el objetivo de determinar el comportamiento de algunos parámetros como factores predictivos de dehiscencia de sutura intestinal en el servicio de Cirugía General del Hospital General Docente Agostinho Neto de Guantánamo durante el periodo 1998 2008, que aborda las siguientes variables: modalidad operatoria, técnica quirúrgica, edad, condiciones generales y tiempo que medio entre el diagnostico y la intervención quirúrgica en los pacientes operados de urgencia. Se concluye que la dehiscencia de sutura intestinal es mas frecuente en la modalidad operatoria urgente ( OR 2.28), la técnica quirúrgica en dos planos (OR 7.19), pacientes mayores de 60 a OR 6.23), las malas condiciones generales (OR 8.58),y el tiempo de diagnostico mayor de 6 horas(OR 6.93) (AU)
