RESUMO
INTRODUCTION: Although the evidence is minimal, an abdominal binder is commonly prescribed after open incisional hernia repair (IHR) to reduce pain. This study aimed to investigate this common postoperative treatment. METHODS: The ABIHR-II trial was a national prospective, randomized, multicenter non-AMG/MPG pilot study with two groups of patients (wearing an abdominal binder (AB) for 2 weeks during daytime vs. not wearing an AB following open IHR with the sublay technique). Patient enrollment took place from July 2020 to February 2022. The primary endpoint was pain at rest on the 14th postoperative day (POD) using the visual analog scale (VAS). The use of analgesics was not systematically recorded. Mixed-effects linear regression models were used. RESULTS: A total of 51 individuals were recruited (25 women, 26 men; mean age 61.4 years; mean body mass index 30.65 kg/m2). The per-protocol analysis included 40 cases (AB group, n = 21; No-AB group, n = 19). Neither group showed a significant difference in terms of pain at rest, limited mobility, general well-being, and seroma formation and rate. Patients among the AB group had a significantly lower rate of surgical site infection (SSI) on the 14th POD (AB group 4.8% (n = 1) vs. No-AB group 27.8% (n = 5), p = 0.004). CONCLUSION: Wearing an AB did not have an impact on pain and seroma formation rate but it may reduce the rate of postoperative SSI within the first 14 days after surgery. Further trials are mandatory to confirm these findings.

INTRODUCTION: spinal fusion is used to treat, among other pathologies, the degenerative intervertebral disc disease. Autologous iliac crest bone grafting is the golden standard treatment for increasing the rate of fusion; however, it isn't free of complications. OBJECTIVES: to investigate whether patients who have posterior iliac crest graft harvesting and are blinded to the donor site, can identify from which side the graft was harvested, and whether the intensity of this pain is related to the amount of graft obtained. MATERIAL AND METHODS: prospective, experimental, randomized and comparative, single-blind study. Adult patients who underwent primary instrumented open posterolateral lumbar fusion with autologous iliac crest bone graft between July 2019 and April 2020 were included. Patients were divided into two randomized groups. The amount of graft to be harvested was according to surgical needs. The patients were asked about pain according to the visual analogue scale in the first, third and sixth months after surgery, always requesting that the most painful side be identified. RESULTS: a total of 44 patients (n = 23 right crest, n = 21 left crest) were analyzed. Most patients were unable to identify the side from which the bone graft was harvested, with a statistically significant difference (p-value 0.0001). CONCLUSION: iliac crest bone graft harvesting is an effective and safe procedure that improves the rates of fusion without increasing the patient's morbidity.
INTRODUCCIÓN: la fusión espinal es utilizada para tratar, entre otras patologías, las enfermedades degenerativas discales. El injerto óseo autólogo de cresta ilíaca es el estándar de oro para aumentar las probabilidades de fusión; sin embargo, no está exento de complicaciones. OBJETIVOS: investigar si los pacientes a los que se les recolecta injerto de cresta ilíaca posterior y son cegados al lado del sitio donante, pueden identificar de qué lado se tomó dicho injerto y si la intensidad de este dolor está en relación con la cantidad de injerto obtenido. MATERIAL Y MÉTODOS: trabajo prospectivo, experimental, aleatorizado y comparativo, simple ciego. Se incluyeron pacientes adultos operados entre Julio de 2019 hasta Abril de 2020, a los cuales se les realizó una cirugía primaria de artrodesis lumbar posterolateral abierta instrumentada, con colocación de injerto óseo autólogo de cresta ilíaca. Se dividió a los pacientes en dos grupos aleatorizados. La cantidad de injerto a recolectar fue de acuerdo a las necesidades quirúrgicas. Se interrogó por el dolor según escala visual analógica al primer, tercer y sexto mes de la cirugía, siempre solicitando que se identifique el lado más doloroso. RESULTADOS: se analizaron 44 pacientes (n = 23 cresta derecha, n = 21 cresta izquierda). La mayoría de los pacientes no lograron identificar el lado del cual se obtuvo el injerto óseo, con una diferencia estadística ampliamente significativa (p = 0.0001). CONCLUSIÓN: la obtención de injerto óseo de cresta ilíaca es un procedimiento efectivo y seguro, que mejora las probabilidades de fusión sin aumentar la morbilidad del paciente.

INTRODUCTION: there are numerous classifications for herniated discs, such classifications guide professionals about the severity of the lesion, the possible clinical picture of the patient, the most appropriate treatment and are undoubtedly a predictive tool to project the possible results of the therapies used. The main purpose of this work is to validate the inter- and intra-observer reliability of the Michigan State University (MSU) classification among the spine surgeons of our service and also to know the risk factors associated with the patients who underwent lumbar discectomy, the most affected disc level, the clinical presentation and the previous treatments performed in the patients treated by our team. MATERIAL AND METHODS: 50 nuclear magnetic resonance (MR) images in axial T2 section corresponding to the "maximum disc herniation" level were selected from patients diagnosed and submitted to meningo-radicular release surgery and single level lumbar discectomy retrospectively in the last two years from our database; these images were distributed among three spine surgeons of our institution. The three spine surgeons gave a specific classification for each MR image based on the MSU classification, then at an interval of seven days one of the three surgeons reclassified the images. The degree of agreement between surgeons was analyzed by calculating interobserver and intraobserver reliability using kappa statistical analysis. RESULTS: the analysis of the kappa coefficient indicated that most of the comparisons by observer gave a "good" concordance strength, the kappa index was higher than 0.64 in all the possible comparisons of the observations. In relation to the number of coincidences, in 60% of the patients there was a total coincidence between the three surgeons, with two coincidences in 24%, and in 16% there was no coincidence at all. For the intraobserver analysis the kappa index was 0.953 with a very good concordance strength, the observed agreement was 96%. CONCLUSION: our research shows a good reliability in the MSU classification among spine surgeons of our institution, as well as very good when reclassifying the intraobserver; we believe that having a sagittal MRI slice to classify them would be very useful, more research is needed to give a prognostic value to the location and size of the hernia and its relation with the surgical indication.
INTRODUCCIÓN: existen numerosas clasificaciones para las hernias de disco, dichas clasificaciones orientan a los profesionales acerca de la gravedad de la lesión, del posible cuadro clínico del paciente, del tratamiento más adecuado y constituyen, sin lugar a dudas, una herramienta predictiva para proyectar los posibles resultados de las terapias utilizadas. El propósito principal de este trabajo es validar la confiabilidad interobservador e intraobservador de la clasificación de la Universidad Estatal de Míchigan (MSU) entre los cirujanos de columna de nuestro servicio y además, conocer los factores de riesgo asociados con los pacientes que fueron intervenidos con discectomía lumbar, el nivel de disco más afectado, la presentación clínica y los tratamientos previos realizados en los pacientes tratados por nuestro equipo. MATERIAL Y MÉTODOS: fueron seleccionadas 50 imágenes de resonancia magnética nuclear (RM) en el corte axial de T2 correspondiente al nivel de "hernia discal máxima" de pacientes diagnosticados y sometidos a cirugía de liberación meningo radicular y discectomía lumbar de un solo nivel de manera retrospectiva en los últimos dos años de nuestra base de datos, estas imágenes se distribuyeron entre tres cirujanos especialistas en columna de nuestra institución. Los tres cirujanos de columna dieron una clasificación específica para cada imagen de RM basada en la clasificación de la MSU, luego en un intervalo de siete días uno de los tres cirujanos volvió a clasificar las imágenes. El grado de acuerdo entre los cirujanos se analizó calculando la confiabilidad interobservador e intraobservador mediante el análisis estadístico kappa. RESULTADOS: el análisis del coeficiente de kappa indicó que en la mayoría de las comparaciones por observador dieron una fuerza de concordancia "buena", el índice de kappa fue superior a 0.64 en todas las posibles comparaciones de las observaciones. En relación con la cantidad de coincidencias, en 60% de los pacientes hubo una coincidencia total entre los tres cirujanos, con dos coincidencias 24% y en 16% no hubo ninguna coincidencia. Para el análisis intraobservador el índice de kappa fue de 0.953 con una fuerza de concordancia muy buena, el acuerdo observado fue de 96%. CONCLUSIÓN: nuestra investigación demuestra una confiabilidad buena en la clasificación de la MSU entre cirujanos de columna de nuestra institución así como muy buena al reclasificar el intraobservador. Creemos que tener un corte sagital de RM para clasificarlas sería de gran utilidad. Se necesitan más investigaciones para dar un valor pronóstico a la ubicación y tamaño de la hernia y su relación con la indicación quirúrgica.

RESUMO
Resumen: Las fracturas por estallido toracolumbar son un gran desafío para los cirujanos de columna, es por ello que el objetivo de este estudio fue realizar una revisión sistemática analizando la literatura actual respecto a los diferentes factores a tener en cuenta en el manejo de las mismas. Material y métodos: Búsqueda sistemática en los sitios PubMed, Cochrane, MedlinePlus. «Thoracolumbar Burst Fractures¼ fueron las palabras claves. Se analizaron los títulos, resúmenes y texto completo a partir de dos observadores independientes. Resultados: Seis estudios han sido incluidos, cinco (83.33%) fueron de cohorte prospectivos y sólo uno (16.67%) retrospectivo. Hubo un total de 289 pacientes entre todas las muestras. La media de edad fue 38.48 años y la relación respecto al sexo fue masculino-femenino de 1.7:1. Conclusión: Las fracturas por estallido toracolumbar siguen siendo controversiales en su tratamiento con bibliografía publicada de bajo nivel de evidencia y sin establecer un consenso en el momento de la toma de decisiones con diferentes opciones según la experiencia y preferencia del cirujano. Sin embargo, la mayoría de los mismos se inclinan hacia el tratamiento con fijación posterior de segmento corto pero sin seguimiento a largo plazo. Respecto al déficit neurológico, la descompresión quirúrgica logró consenso entre todos los cirujanos.
Abstract: Thoracolumbar burst fractures are a great challenge for spine surgeons and that is why the aim of this study was to perform a systematic review analyzing the current literature regarding the different factors to take into account in their management. Material and methods: Systematic search in PubMed, Cochrane, MedlinePlus sites. «Thoracolumbar Burst Fractures¼ were the keywords. Titles, abstracts and full text were analyzed from two independent observers. Results: Six studies were included, five (83.33%) were prospective cohort studies and only one (16.67%) was retrospective. There were a total of 289 patients among all samples. The mean age was 38.48 years and the sex ratio was male to female of 1.7:1. Conclusion: Thoracolumbar burst fractures remain controversial in their treatment with published literature of low level of evidence and without establishing a consensus at the time of decision making with different options depending on the surgeon's experience and preference. However, most of them are inclined towards treatment with short segment posterior fixation but without long-term follow-up. Regarding neurological deficit, surgical decompression achieved consensus among all surgeons.
RESUMO
RESUMEN La meningitis por Mycobacterium tuberculosis es la forma extrapulmonar más letal de la tuberculosis activa, con alta prevalencia en los países en desarrollo, lo que constituye un problema de salud pública. Las formas de presentación extrapulmonar que comprometen el sistema nervioso incluyen la tuberculosis meníngea, el granuloma tuberculoso, el absceso tuberculoso y la radiculomielitis, con una presentación clínica inespecífica que dificulta su oportuno diagnóstico, sumado a la falta de pruebas rápidas con alta sensibilidad y especificidad, el alto costo y la pobre asequibilidad a las pruebas en muchos países. El diagnóstico se basa en pruebas microbiológicas, moleculares y en aquellas basadas en la respuesta del huésped. El diagnóstico microbiológico se basa en la tinción de Ziehl-Neelsen y en el cultivo, este último considerado durante mucho tiempo la prueba diagnóstica de oro. El diagnóstico molecular es más preciso utilizando las pruebas de amplificación de ácidos nucleicos, la reacción en cadena de la polimerasa, la prueba de GeneXpert MTB/RIF y la prueba Xpert MTB/ RIF Ultra. Debido a la ausencia de una prueba rápida, existen escalas que ayudan a orientar el diagnóstico del paciente, dentro de las cuales merecen citarse la de Thwaites y la de Marais. El tratamiento de la tuberculosis de cepas sensibles incluye un esquema estructurado con isoniazida, rifampicina, pirazinamida y etambutol, sin embargo, en la actualidad la resistencia a los antimicrobianos constituye un problema, por lo cual el tratamiento en la tuberculosis multirresistente debe ser individualizado, con un régimen de tratamiento prolongado.
SUMMARY Mycobacterium tuberculosis meningitis is the most lethal extrapulmonary form of active tuberculosis with high prevalence in developing countries, which constitutes a public health problem. The extrapulmonary presentation that compromise the nervous system include meningeal tuberculosis, tuberculous granuloma, tuberculosis abscess and radiculomyelitis. A nonspecific clinical presentation, the lack of rapid tests with high sensitivity and specificity, the high cost and poor affordability of testing in many countries make the diagnosis more complicated. The diagnosis is based on microbiological, molecular, and host response based testing. Microbiological diagnosis is based on Ziehl - Neelsen staining and culture, the latter long considered the gold standard diagnostic test. Molecular diagnosis is more accurate using nucleic acid amplification tests, the chain reaction of polymerase, the GeneXpert MTB / RIF test, and the Xpert MTB / RIF Ultra test. Given the absence of a rapid test, there are scales that help guide the patient's diagnosis, within which the Thwaites Scale and the Marais Scale deserve to be mentioned. The treatment of tuberculosis of susceptible strains includes a structured regimen with isoniazid, rifampicin, pyrazinamide and ethambutol, however, antimicrobial resistance is currently a problem for which the treatment of multidrug-resistant tuberculosis must be individualized, with a long-term treatment regimen.

Information on weaning techniques in the tropics is scarce, particularly regarding the long-term effect of temporary early cow-calf separation or restricted suckling. Therefore, we studied the effects of these two handling practices on well-being and performance at 150â¯days postpartum in fifteen zebu cow-calf pairs randomly assigned to three treatments. Continuous suckling (CS) where calves remained with their dams from birth to weaning; restricted suckling (RS) calves were allowed to suckle 30â¯min/day from Day 34 until weaning at Day 150 and kept separated the rest of the time; temporary separation (TS) calves were separated for 72â¯h from their dams from Day 33 to 36 but remained with their dams the rest of the time. Blood samples and behavioral data were collected on Days 32-36 (1st period) and 149-153 (2nd period). In the 1st period, a greater percentage of RS and TS calves were observed close to the fence line (<10â¯m) that separated them from their dams (P < 0.0001) and vocalized more than CS calves (Pâ¯<â¯0.0001), while in the 2nd period, RS calves had the highest cortisol concentration and vocalization rate (Pâ¯<â¯0.05). Similarly, during the 1st period, a greater percentage of RS and TS cows were observed close to the fence line than CS cows (Pâ¯<â¯0.0001), with TS cows vocalizing the most (P =â¯0.001). In the 2nd period, RS cows had greater cortisol concentration than TS (Pâ¯=â¯0.037) and CS cows (P = 0.003). More TS and CS cows than RS were observed close to the fence line (Pâ¯=â¯0.03 and Pâ¯=â¯0.05). On Day 150, TS calves and cows vocalized more than RS and CS animals (Pâ¯<â¯0.0001). Before calf-cow separation, 27 out of 45 cows were cycling (CSâ¯=â¯10; RSâ¯=â¯6; TSâ¯=â¯11). After separation, 12 of the remaining 18 cows resumed ovarian activity (CSâ¯=â¯3; RSâ¯=â¯5; TSâ¯=â¯4), and all cows were cycling after estrous synchronization treatment. The pregnancy rate was similar between CS, RS, and TS (60, 53, and 60% respectively). In conclusion, temporary separation increased calf distress response to definitive weaning even four months later, while restricted suckling seemed to reduce it.

Resumen Introducción: Los nódulos tiroideos son un crecimiento localizado en el tejido tiroideo, aproximadamente el 8 % son malignos, y el ultrasonido es el método ideal para detectarlos. Objetivo: Determinar cuáles son los hallazgos ecográficos que pueden sugerir una mayor probabilidad de malignidad del nódulo tiroideo. Metodología: Estudio descriptivo de tipo corte transversal en pacientes con nódulo tiroideo en una institución prestadora de salud de Neiva. Resultados: Se evaluaron 63 pacientes con un promedio de edad de 52 años, 95 % fueron femeninos y el 5 % masculinos. El 71 % presentaron nódulos tiroideos benignos, y el 10 % nódulos malignos. En el 100 % de los nódulos tiroideos malignos se encontró vascularidad aumentada, microcalcificaciones, adenopatías asociadas, bordes irregulares y componente sólido, y los hallazgos con respecto a hipoecogenicidad y diámetro anteroposterior mayor al transverso (más alto que ancho), se encontró en el 83 % siendo estadísticamente significativos. La sensibilidad de los hallazgos ecográficos supera el 80 %, excepto la variable "tamaño del nódulo mayor a 1 centímetro". Conclusiones: Los hallazgos ecográficos como adenopatías y el diámetro anteroposterior mayor al transverso son indicadores potenciales de nódulos tiroideos malignos, el tamaño mayor a un centímetro no siempre es predictor de malignidad, sin embargo debido al tamaño de la muestra en nuestro estudio no es posible generalizarlo como un factor determinante para la realización de biopsia, por ende recomendamos el seguimiento de los nódulos teniendo en cuenta los criterios ecográficos de malignidad y la clasificación TIRADS para tomar decisiones con respecto a las biopsias tiroideas.
Abstract Introduction: Thyroid nodules are a localized growth in the thyroid tissue, approximately 8% are malignant, and an ultrasound is the ideal method to detect them. Objective: Determine which are the ultrasound findings that may suggest an increased probability of thyroid nodule malignancy. Methodology: Descriptive cross-sectional study amongst patients with thyroid nodule in a healthcare institution in Neiva. Results: A total of 63 patients were evaluated with an average age of 52 years, 95% were female and 5% male. Seventy-one percent had benign thyroid nodules, and 10% malignant nodules. In 100% of malignant thyroid nodules, increased vascularity, microcalcifications, associated adenopathies, irregular borders and solid component were found, and the findings regarding hypoechogenicity and anteroposterior diameter greater than the transverse (higher than wide), were found in 83%, being statistically significant. The sensitivity of ultrasound findings exceeds 80%, except for the variable nodule size greater than 1 centimetre. Conclusions: Ultrasound findings such as adenopathies and anteroposterior diameters greater than the transverse one are potential indicators of malignant thyroid nodules, the size greater than one centimetre is not always a predictor of malignancy; however, due to the size of the sample in our study it is not possible to generalize it as a determining factor for biopsy. Therefore, we recommend monitoring the nodules considering the ultrasound criteria for malignancy and the TIRADS classification to make decisions regarding thyroid biopsies.

BACKGROUND: s: Incisional hernias may occur in 10-25% of patients undergoing laparotomy. In cases of a surgical site infection (SSI) after incisional hernia repair (IHR) secondary operative intervention with mesh removal are often needed. There is only minimal data available in the literature regarding the treatment of a wound infection with negative pressure wound therapy (NPWT). Conducting the study at hand, we aimed to provide more evidence on this topic. METHODS: From April to June 2020 a monocentric retrospective study has been performed. Patients who underwent NPWT due to a SSI with mesh involvement following open IHR from 2007 to 2020 were included. The primary endpoint was the mesh removal rate in the end of NPWT. Main secondary endpoints were the duration of NPWT and the amount of NPWT procedures. RESULTS: The data of 30 patients were extracted. The average age was 65.9 years (9.9). A total of 13 individuals were male and 17 females. The BMI was on average 31.1 kg/m2 (4.9). All patients received a polypropylene mesh. The average duration of NPWT was 31.3 days (22.1). The first wound revision with initiation of a NPWT was conducted on average 31.1 days (34.0) after IHR. The average amount of NPWT procedures was 8.3 (7.2). In 5 of 30 patients (16.6%) the mesh was removed (Open sublay group n = 4 (36.34%) vs. open onlay group n = 1 (5.26%), p = 0.047). CONCLUSION: In cases of SSI following IHR the NPWT may facilitate mesh selvage. Further trials with a larger sample size are mandatory to confirm our hypothesis.
RESUMO
BACKGROUND: Some studies have suggested a relationship between type 2 diabetes mellitus (T2DM) and increased incidence of melanoma. Efforts are under way to identify preventable and treatable factors associated with greater melanoma aggressiveness, but no studies to date have examined the relationship between T2DM and the aggressiveness of cutaneous melanoma at diagnosis. OBJECTIVES: To explore potential associations between T2DM, glycaemic control and metformin treatment and the aggressiveness of cutaneous melanoma. METHODS: We conducted a cross-sectional multicentric study in 443 patients diagnosed with cutaneous melanoma. At diagnosis, all patients completed a standardized protocol, and a fasting blood sample was extracted to analyse their glucose levels, glycated haemoglobin concentration and markers of systemic inflammation. Melanoma characteristics and aggressiveness factors [Breslow thickness, ulceration, tumour mitotic rate (TMR), sentinel lymph node (SLN) involvement and tumour stage] were also recorded. RESULTS: The mean (SD) age of the patients was 55·98 (15·3) years and 50·6% were male. The median Breslow thickness was 0·85 mm. In total, 48 (10·8%) patients were diagnosed with T2DM and this finding was associated with a Breslow thickness > 2 mm [odds ratio (OR) 2·6, 95% confidence interval (CI) 1·4-4·9; P = 0·004)] and > 4 mm (OR 3·6, 95% CI 1·7-7·9; P = 0·001), TMR > 5 per mm2 (OR 4·5, 95% CI 1·4-13·7; P = 0·009), SLN involvement (OR 2·3, 95% CI 1-5·7; P = 0·038) and tumour stages III-IV (vs. I-II) (OR 3·4, 95% CI 1·6-7·4; P = 0·002), after adjusting for age, sex, obesity, alcohol intake and smoking habits. No significant associations emerged between glycated haemoglobin levels, metformin treatment and melanoma aggressiveness. CONCLUSIONS: T2DM, rather than glycaemic control and metformin treatment, is associated with increased cutaneous melanoma aggressiveness at diagnosis.

BACKGROUND: The transversus abdominis plane block is a regional anesthesia technique. Recently, its impact on early chronic pain and the cumulative need of analgesic medication following inguinal hernia repair is being monitored. In terms of effectiveness and patient safety, it remains unclear whether the approach should be conducted preoperatively through ultrasound guidance, or through intraoperative visual guidance.The study at hand aims to provide more evidence on this topic. METHODS: A monocentric retrospective matched pair analysis was performed. The intraoperative visual guided and ultrasound guided -transversus abdominis plane block prior to inguinal hernia repair in transabdominal preperitoneal technique were consecutively compared in regard to analgesic effectiveness and complication rate. The data of individuals who were operated on from June 2007 to February 2019 were analyzed. The matching criteria were ASA-Score, Gender, Age ( ±6 years), and hernia size (<1,5 cm, 1,5-3 cm, >1,5 cm). RESULTS: A total of 116 patients were enrolled. Both groups were homogenous in terms of age, gender contribution, body mass index, ASA-Score, hernia type, and size. The pain score at the postoperative anesthesia care unit was lower in the ultrasound-guided-transversus abdominis plane group without being statistically significant (VAS-Score: 0.67 vs.0.84). Patients of the ultrasound-guided-transversus abdominis plane group received significantly less metamizole on the day of operation (1.29 g (0.96) vs. 1.68 g (0.70), p = 0.015). CONCLUSION: Due to our findings, we assume that the ultrasound-guided-transversus abdominis plane -Block may reduce postoperative pain and analgesic consumption more effectively than the visual-guided-transversus abdominis plane lock. Further prospective clinical trials are mandatory.
RESUMO
PURPOSE: Patients suffering from a ventral hernia can be treated by laparoscopic ventral hernia repair (VHR) with the intraperitoneal onlay mesh (IPOM) technique. To reduce early postoperative pain and the analgesic cumulative need for medication (CNM), the transversus abdominis plane (TAP) block has recently been investigated and implemented in hernia surgery. We aimed to investigate its impact when conducting a VHR in IPOM technique. METHODS: A single center retrospective observational matched pair analysis has been conducted from March to April 2020. The data of patients who underwent VHR in IPOM technique with prior TAP block administration were enrolled. The matching was performed using the variables age ( ±5 years), gender, type of surgery, BMI and ASA stage. RESULTS: 52 patients were enrolled. Among the individuals of the TAP block group, (18 males, 8 females) the average age was 52.4 (15.9). The average BMI was 29.0 (3.95) kg/m2. 14 patients suffered from an umbilical, 9 from an incisional, and three from an epigastric hernia. Except for COX-2-inhibitors, (TAP group: 41.9 mg (31.0), Control group 9.23 (22.1), p < 0.001) the analgesic CNM of both groups did not statistically differ from each other. The literature review yielded four relevant publications (n = 100). The authors stated a positive impact of the TAP block on early postoperative pain and analgesic medication consumption. CONCLUSION: The TAP block prior to laparoscopic ventral hernia repair may reduce early postoperative pain and analgesic medication consumption in selected patients. More randomized clinical trials are needed to confirm these findings.

Abstract Introduction: Obesity is one of the most severe public health problems of the 21st century. During childhood, the mother is the main care provider and model of the health the son´s behaviors; and thus, factors such as the mother's objectives and the food choices habits have an impact on the body mass index of the son. Objective: To identify if the objectives and food choices of the mother, as well as the specific food can predict the body mass index in pre-school children. Method: This is a descriptive and correlational study. 217 dyads (mother and pre-school son) participated. The Food Choices Questionnaire, the Integral Questionnaire on Feeding Practices and the Food Frequency Questionnaire were administered. Weight and size were measured. The body mass index was calculated and nutritional status was estimated. Descriptive and inferential statistics, including multiple linear regression, were obtained. Results: Convenience as an objective, the consumption of dairy products and sweet cereals, the age, and the mother's body mass index, had an impact on the body mass index of the son and accounted for 28.3% of the explained variance. Conclusion: The studied variables had a minimal contribution to the BMI of the sons. It is recommended to carry out multivariate studies in order to explain more integrally the excess of weight among pre-school children.

RESUMO
PURPOSE: Laparoscopic inguinal hernia repair (IHR) may lead to early postoperative pain. Therefore, opioid and non-opioid analgesic agents are often administered in the post-anesthesia care unit (PACU). To reduce the postoperative cumulative need of analgesic medication, as well as to accelerate the physical recovery time, the transversus abdominis plane (TAP) block has recently been studied. The TAP block is a regional anesthesia technique. Even though there is evidence about the efficacy of the block used in procedure such as an open inguinal hernia repair, the evidence regarding its use for the TAPP (transabdominal preperitoneal) technique remains low. We aim to provide more sufficient evidence regarding this topic. METHODS: A monocentric retrospective observational study investigating the effect of the TAP block prior to primary IHR in TAPP technique was conducted. The data of 838 patients who were operated on using this technique from June 2007 to February 2019 were observed. 72 patients were excluded because of insufficient information regarding their analgesic medication protocol. The patients' data were taken from their files. RESULTS: The patients in the TAP block group (n = 364) did not differ statistically significantly compared to the control group (n = 402) in terms of gender, BMI and age. Individuals of the TAP block group experienced less postoperative pain in the PACU (p < 0.001) and received less analgesic medication (morphine, oxycodone, piritramide, acetaminophen; p < 0.001). CONCLUSION: We assume that the TAP block is a sufficient approach to reduce postoperative pain and analgesic medication administration for IHR in TAPP technique.

INTRODUCTION: Recent medical investigations suggest that HLA-G, due to its tolerogenic properties, can be used as a biomarker in the diagnosis, treatment, and prognosis of different neoplasms. This observational prospective pilot study aims at detecting sHLA-G in the serum and saliva of patients diagnosed with colorectal cancer (CRC). For this purpose, we compared the expression of sHLA-G from patients with a control sample from a healthy population. MATERIALS AND METHODS: Using the specific enzyme-linked immunosorbent assay (ELISA) method, the expression of sHLA-G in the serum and saliva samples from patients affected by CRC (n = 20) and in a control sample (n = 10) were analyzed. RESULTS: The data showed that in patients with CRC, salivary sHLA-G values were significantly higher than in the control group (18.84 U/ml versus 6.3 U/ml, p = 0.036). In addition, higher levels of sHLA-G were observed in the saliva of patients with CRC in more advanced stages, compared with patients in early stages (24.2 U/ml vs. 8.1 U/ml, p = 0.019). A significant correlation was observed between the concentration of sHLA-G in the serum and saliva of the analyzed samples (Spearman correlation 0.7, p = 0.004). CONCLUSIONS: This study demonstrates, for the first time, the possibility of detecting sHLA-G in the saliva of patients with CRC, resulting in a less invasive alternative to venipuncture. Likewise, we propose that sHLA-G could be an attractive molecular target based on its significant high levels in advanced stages.

Resumen: La auscultación de señales basada en un estetoscopio estándar y/o electrónico no solo incluye sonidos internos del cuerpo, también incluye frecuentemente ruido externo de interferencia con componentes en el mismo rango. Esta forma de examinar es incluso afectada por los umbrales auditivos variantes de los profesionales de la salud y el grado de experiencia en reconocimiento de indicadores peculiares. Además, los resultados son a menudo caracterizados en términos cualitativos descriptivos sujetos a interpretaciones individuales. Para direccionar esta preocupación, los estudios presentados en este artículo contienen un procesamiento concurrente de las componentes dominantes de sonidos del corazón (HS) y del pulmón (HS), y una etapa de acondicionamiento que incluye la reducción de HS presente en señales LS. Específicamente, la transformada de Hilbert fue una técnica de caracterización para HS. En el caso de señales enfocadas a LS, las técnicas de detección de actividad de voz y el cálculo de umbrales de algunos componentes de los vectores acústicos de Coeficientes Cepstrales en Frecuencia Mel (MFCC), fueron útiles en la caracterización de eventos acústicos asociados. Las fases de inspiración y expiración fueron diferenciadas por medio de la sexta componente de MFCC. Con el fin de evaluar la eficiencia de esta aproximación, proponemos los Modelos Ocultos de Markov con Modelos Mesclados Gaussianos (HMM-GMM). Los resultados utilizando esta forma de detección son superiores cuando se desarrolla la clasificación con modelos HMM-GMM, la cual refleja las ventajas de la forma de detección cuantificable y clasificación sobre la aproximación clínica tradicional.
Abstract: A standard and/or electronic stethoscope based auscultatory signals include not only the internal sounds of the body but also interfering external noise often with similar frequency components. This form of examination is also affected by varying thresholds of clinical practitioner's hearing and degree of experience in recognition of peculiar auscultatory indicators. Further, the results are often characterized in qualitative descriptive terms subject to individual's interpretation. To address these concerns, presented studies include concurrent processing of dominant heart (HS) and lung (LS) sounds components and a conditioning stage involving HS presence reduction within LS focused signals. Specifically as determined, the Hilbert transform was a technique of choice in HS characterization. In the case of LS focused signals, the speech activity detection techniques (VAD) and the thresholds calculation of some components of acoustic vectors of Cepstral Coefficients in Mel Frequency (MFCC), were useful in characterization of associated acoustic events. The phases of inspiration and expiration were differentiated by means of the sixth component of MFCC. In order to evaluate the efficiency of this approach, we propose Hidden Markov Models with Mixed Gaussian Models (HMM-GMM). The results utilizing this form of detection are superior when performing classification with HMM-GMM models, which reflect the advantages of presented form of quantifiable detection and classification over traditional clinical approach.
RESUMO
STUDY QUESTION: Is it possible to determine the receptivity status of an endometrium by combined quantitative reverse transcription PCR (RT-qPCR) expression analysis of genes involved in endometrial proliferation and immunity? SUMMARY ANSWER: The new ER Map®/ER Grade® test can predict endometrial receptivity status by RT-qPCR using a new panel of genes involved in endometrial proliferation and the maternal immune response associated to embryonic implantation. WHAT IS KNOWN ALREADY: The human endometrium reaches a receptive status adequate for embryonic implantation around Days 19-21 of the menstrual cycle. During this period, known as the window of implantation (WOI), the endometrium shows a specific gene expression profile suitable for endometrial function evaluation. The number of molecular diagnostic tools currently available to characterize this process is very limited. In this study, a new system for human endometrial receptivity evaluation was optimized and presented for the first time. STUDY DESIGN, SIZE, DURATION: ER Map®/ER Grade® validation was achieved on 312 endometrial samples including fertile women and patients undergoing fertility treatment between July 2014 and March 2016. Expression analyses of 184 genes involved in endometrial receptivity and immune response were performed. Samples were additionally tested with an independent endometrial receptivity test. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 96 fertile women and 120 assisted reproduction treatment (ART) patients participated in the study. Endometrial biopsy samples were obtained at LH + 2 and LH + 7 days in fertile subjects in a natural cycle and at the window of implantation (WOI) in patients in a hormone-replacement therapy (HRT) cycle. Total RNA was purified, quality-checked and reverse-transcribed. Gene expression was quantified by high-throughput RT-qPCR and statistically analyzed. Informative genes were selected and used to classify samples into four different groups of endometrial receptivity status. MAIN RESULTS AND THE ROLE OF CHANCE: Significantly different gene expression levels were found in 85 out of 184 selected genes when comparing LH + 2 and LH + 7 samples (paired t-test, P < 0.05). Gene ontology analyses revealed that cell division and proliferation, cell signaling and response, extracellular organization and communication, immunological activity, vascular proliferation, blood pressure regulation and embryo implantation are the most over-represented biological terms in this group of genes. Principal component analysis and discriminant functional analysis showed that 40 of the differentially expressed genes allowed accurate classification of samples according to endometrial status (proliferative, pre-receptive, receptive and post-receptive) in both fertile and infertile groups. LARGE SCALE DATA: N/A. LIMITATIONS, REASONS FOR CAUTION: To evaluate the efficacy of this new tool to improve ART outcomes, further investigations such as non-selection studies and randomized controlled trials will also be required. WIDER IMPLICATIONS OF THE FINDINGS: A new comprehensive system for human endometrial receptivity evaluation based on gene expression analysis has been developed. The identification of the optimal time for embryo transfer is essential to maximize the effectiveness of ART. This study is a new step in the field of personalized medicine in human reproduction which may help in the management of endometrial preparation for embryo transfer, increasing the chances of pregnancy for many couples. STUDY FUNDING/COMPETING INTEREST(S): The authors have no potential conflict of interest to declare. No external funding was obtained for this study.
