RESUMEN Introducción: los pacientes con COVID-19 ingresan en mayor proporción a asistencia respiratoria mecánica, aumentando: el riesgo de neumonía asociada a ventilador (NAV) las tasas de mortalidad, los días de permanencia en las unidades de terapia intensiva (UCI) y los costos sanitarios. Objetivo: determinar la Mortalidad intrahospitalaria de pacientes con COVID-19 complicados con neumonías bacterianas en asistencia respiratoria mecánica en Cuidados Intensivos de Adultos en un Hospital del Paraguay durante los años 2020 a 2021. Metodología: estudio analítico de tipo cohorte retrospectiva. Se registraron variables demográficas, comorbilidades, puntajes en scores de gravedad como el APACHE II al ingreso, la cifra más baja de oxigenación durante la internación expresado por la PaO2 / FIO2, días de ventilación, colocación en decúbito prono, traqueotomía, medidas terapéuticas farmacológicas y no farmacológicas, días de internación, así como las complicaciones y la mortalidad. Resultados: fueron incluidos 214 pacientes, 135 ingresaron a asistencia respiratoria mecánica (ARM) de los cuales 58 (42,9 %) desarrollaron NAV, con edad mediana de 52 años (40-60). Los microorganismos de NAV fueron cocos Gram negativos en 98,3 %, incluyendo Acinetobacter baumanii en 46,5 %, Klebsiella pneumoniae en 22,8 %, Pseudomona aeruginosa en 15,5 % y 5,2 % Stenotrophomona maltofilia. La mortalidad intrahospitalaria fue del 44,8 %. Los menores de 50 años tienen una sobrevida mayor que los mayores (34 días vs 22 días, con p de 0,026). Conclusión: la mortalidad intrahospitalaria fue del 44,8 %. La edad fue un factor de riesgo independiente para la mortalidad en pacientes con NAV, por lo que los profesionales de la salud deben estar atentos a la posibilidad de NAV en pacientes que requieren asistencia respiratoria mecánica, especialmente en pacientes mayores de 50 años.

ABSTRACT Introduction: patients with COVID-19 are more likely to require mechanical ventilation, which increases the risk of ventilator-associated pneumonia (VAP), mortality rates, length of stay in intensive care units (ICUs), and healthcare costs. Objective: to determine the in-hospital mortality of patients with COVID-19 complicated by bacterial pneumonia on mechanical ventilation in Adult Intensive Care in a Hospital in Paraguay during the years 2020 to 2021. Methodology: this is a retrospective cohort analytical study. Demographic variables, comorbidities, severity scores such as APACHE II on admission, the worst oxygenation during hospitalization expressed by PaO2/FiO2, days of ventilation, prone position, tracheostomy, pharmacological and non-pharmacological therapeutic measures, days of hospitalization, as well as complications and mortality were recorded. Results: a total of 214 patients were included, 135 were admitted to mechanical ventilation (MRA), of which 58 (42.9%) developed VAP, with a median age of 52 years (40-60). VAP microorganisms were Gram-negative cocci in 98.3%, including Acinetobacter baumanii in 46.5%, Klebsiella pneumoniae in 22.8%, Pseudomona aeruginosa in 15.5%, and Stenotrophomona maltophilia in 5.2%. In-hospital mortality was 44.8%. Those under 50 years of age have a longer survival than those older (34 days vs. 22 days, with p of 0.026). Conclusion: the overall mortality rate was 44.8%. Age was an independent risk factor for mortality in patients with VAP, so healthcare professionals should be aware of the possibility of VAP in patients who require mechanical ventilation, especially in patients over 50 years of age.

Abstract Objective: To provide guidelines on the coronavirus disease 2019 (COVID-19) vaccination in patients with immune-mediated rheumatic diseases (IMRD) to rheumatologists considering specific scenarios of the daily practice based on the shared-making decision (SMD) process. Methods: A task force was constituted by 24 rheumatologists (panel members), with clinical and research expertise in immunizations and infectious diseases in immunocompromised patients, endorsed by the Brazilian Society of Rheumatology (BSR), to develop guidelines for COVID-19 vaccination in patients with IMRD. A consensus was built through the Delphi method and involved four rounds of anonymous voting, where five options were used to determine the level of agreement (LOA), based on the Likert Scale: (1) strongly disagree; (2) disagree, (3) neither agree nor disagree (neutral); (4) agree; and (5) strongly agree. Nineteen questions were addressed and discussed via teleconference to formulate the answers. In order to identify the relevant data on COVID-19 vaccines, a search with standardized descriptors and synonyms was performed on September 10th, 2021, of the MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, and LILACS to identify studies of interest. We used the Newcastle–Ottawa Scale to assess the quality of nonrandomized studies. Results: All the nineteen questions-answers (Q&A) were approved by the BSR Task Force with more than 80% of panelists voting options 4—agree—and 5—strongly agree—, and a consensus was reached. These Guidelines were focused in SMD on the most appropriate timing for IMRD patients to get vaccinated to reach the adequate covid-19 vaccination response. Conclusion: These guidelines were developed by a BSR Task Force with a high LOA among panelists, based on the literature review of published studies and expert opinion for COVID-19 vaccination in IMRD patients. Noteworthy, in the pandemic period, up to the time of the review and the consensus process for this document, high-quality evidence was scarce. Thus, it is not a substitute for clinical judgment.

RESUMO: Na espécie suína os tumores são pouco diagnosticados devido a curta vida útil dos animais de produção. Normalmente não causam sinais clínicos, sendo, muitas vezes, encontrados no momento do abate. Um reprodutor com dois anos de idade, da raça Large White, utilizado no manejo reprodutivo de uma granja, sem histórico de problemas pré-existentes, foi examinado em função de lesões na pele da bolsa escrotal. Foram coletadas amostras de segmentos de pele contendo lesões para o diagnóstico histopatológico e imunohistoquímico. Microscopicamente os nodos em bolsa escrotal consistiam em neoplasias mal demarcadas, altamente celulares, expansivas e multifocalmente invasivas composta por endoteliócitos imaturos organizados em formações neovasculares. As células tumorais eram pleomórficas, levemente ovais a fusiformes com citoplasma eosinofílico e núcleos hipercromáticos e com um a três nucléolos. Todos os nódulos analisados foram compatíveis com hemangiossarcoma. Para a quantificação da angiogênese tecidual, após a avaliação imunohistoquímica, as células neoplásicas imunoexpressaram os anticorpos monoclonais CD31 e Fator VIII, através da identificação de proteínas expressas na superfície das células endoteliais. Observou-se o marcador de proliferação celular Ki67 positivo em aproximadamente 10% das células neoplásicas, demonstrando um alto grau de malignidade. O hemangiossarcoma na espécie suína já foi identificado em vários órgãos e tecidos, mas, até o momento, nenhum trabalho demonstrou o diagnóstico na pele da bolsa escrotal, como reportado, ineditamente, neste estudo. Face o exposto, espera-se que este relato contribua para a frequência de neoplasias encontradas na espécie suína.

ABSTRACT: Tumors are rarely diagnosed in swine specie because of the short lifespan of production animals. Normally, these tumors do not present any clinical signs and are often detected at the time of slaughter. A 2-year-old Large White boar, used in the reproductive management of a farm and without a history of pre-existing problems, was examined for skin lesions on the scrotum. Samples were collected from skin segments containing lesions for histopathological and immunohistochemical diagnosis. Microscopically, the nodes in the scrotum pouch consisted of poorly demarcated, highly cellular, expansile, and multifocally invasive neoplasms, composed of immature endotheliocytes organized into neovascular formations. The tumor cells were pleomorphic, slightly oval to spindle-shaped, with eosinophilic cytoplasm and hyperchromatic nuclei with one to three nucleoli. All the nodules analyzed were compatible with hemangiosarcoma. After immunohistochemical evaluation, for the quantification of tissue angiogenesis the neoplastic cells immunoexpressed the CD31 monoclonal antibodies and factor VIII, through the identification of proteins expressed on the surface of endothelial cells. The Ki67 cell proliferation marker was positive in approximately 10% of the neoplastic cells, demonstrating a high degree of malignancy. Hemangiosarcoma in swine species has already been identified in several organs and tissues; however, to date, no study has demonstrated the diagnosis of this condition on the skin of the scrotum, as reported in this study. Therefore, it is expected that this report will contribute to the knowledge of the frequency of neoplasms in swine species.

ABSTRACT Introduction: The COVID-19 pandemic has led to changes affecting the healthcare systems and the approach to the infectious diseases worldwide. The hope to regain a certain level of “normalcy” relays on the development of vaccines. Objectives: The aim of this study was to describe attitudes towards the COVID-19 vaccine in the Paraguayan population, exploring factors that could be addressed to support the SARS-CoV-2 vaccination campaign. Materials and methods: Cross sectional and descriptive study. Participants were recruited through an Internet-based survey, spread through social media, during the month of March 2021. All participants received complete information about the aim of the study, privacy and data-processing. Results: Of the 2,297 participants, 67.9% (n=1,559) were women, 49.9% (n=1,147) were employed, 89.1% (n=2,046) reported a university education, and 96.6% (n=2218) were from urban areas. Overall, 81.8% (n=1,879) of participants stated that they were willing to be vaccinated against COVID-19 if a vaccine was available. A significant relationship has been found between having applied for the influenza vaccine and the intention to get vaccinated against COVID-19 (p <0.0001), with an OR: 3.09 (95% CI 2.1-4.5). Conclusion: The percentage of participants inclined to be vaccinated against the COVID-19 is similar to that of those expecting a proper immunization from the vaccine. Government and health agencies should make an effort to provide accurate information that responds to people's concerns about vaccination, at any level of society.

RESUMEN Introducción: la pandemia de COVID-19 ha provocado cambios que afectan a los sistemas sanitarios y al enfoque de las enfermedades infecciosas en todo el mundo. La esperanza de recuperar un cierto nivel de "normalidad" depende del desarrollo de vacunas. Objetivos: el objetivo de este estudio fue describir las actitudes hacia la vacuna COVID-19 en la población paraguaya, explorando los factores que podrían abordarse para apoyar la campaña de vacunación contra el SARS-CoV-2. Materiales y métodos: estudio transversal y descriptivo. Los participantes fueron reclutados a través de una encuesta por Internet, difundida a través de las redes sociales, durante el mes de marzo de 2021. Todos los participantes recibieron información completa sobre el objetivo del estudio, la privacidad y el procesamiento de datos. Resultados: de los 2297 participantes, el 67,9 % (n=1559) eran mujeres, el 49,9 % (n=1147) estaban empleados, el 89,1 % (n=2046) declararon tener estudios universitarios y el 96,6 % (n=2218) eran de zonas urbanas. En general, 81,8 % (n=1879) de los participantes declararon estar dispuestos a vacunarse contra la COVID-19 si hubiera una vacuna disponible. Se encontró una relación significativa entre haber recibido la vacuna contra la gripe y la intención de vacunarse contra la COVID-19 (p <0,0001), con una OR de 3,09 (95% IC 2,1-4,5). Conclusión: el porcentaje de participantes inclinados a vacunarse contra la COVID-19 es similar al de los que esperan recibir una inmunización adecuada gracias a la vacuna. El gobierno y las agencias de salud deben hacer un esfuerzo para proporcionar información precisa que responda a las preocupaciones de la gente sobre la vacunación, en cualquier nivel de la sociedad.

Abstract Factors that influence the acceptability and preferences of consumers have been perceived as sensory attributes, such as color, appearance, flavor, and texture. Understanding which attributes are most important for overall liking would be helpful to establish meaningful criteria for product grading. Thus, in addition to the overall chemical and sensory qualities, it is important to appreciate which sensory attributes make a product pleasant or unpleasant to a consumer. In this context, the aim of this study was to evaluate the sensory attribute that contributes most to the overall liking by a gamma regression model using different formulations of mixed fruit jams made with Brazilian Cerrado fruits. Based on the proposed model, we concluded that appearance was the most important predictor of the overall liking of the assessors.

RESUMO: O manejo do mofo branco (Sclerotinia sclerotiorum) tem sido um dos principais limitantes de produção enfrentados por produtores de soja. Tendo em vista a complexidade do manejo desta doença e da estrutura de resistência do patógeno, o presente trabalho foi conduzido nos municípios de Guarapuava e Palmas - Paraná visando o manejo do mofo branco na cultura da soja utilizando palhadas de cereais de inverno, aveia, centeio e triticale. Inicialmente, cultivou-se os diferentes cereais de inverno, simultaneamente, nas duas áreas de estudo (Guarapuava e Palmas - PR). Avaliou-se a produção de palhada, a altura de plantas, a massa verde e seca da parte aérea. Posteriormente, semeou-se soja ‘BMX Apolo’ sobre as palhadas de cereais e avaliou-se a incidência e a severidade do mofo branco. No experimento in vitro, adicionou-se 20 escleródios cobertos por uma camada de palhas (aveia, centeio e triticale) e após 98 dias, observou-se germinação carpogênica somente no tratamento testemunha. Independentemente do local de estudo, o centeio destacou-se com maiores altura e massa verde. O cultivo sobre palhada de cereais de inverno reduziu a incidência e severidade de mofo branco com destaque para a palhada de centeio, reduzindo a incidência da doença em 77,7% e 76,6%, em Palmas e Guarapuava, respectivamente.

ABSTRACT: The management of white mold (Sclerotinia sclerotiorum(Lib.) De Bary) has been one of the main production limitations faced by soybean (Glycine max L.) producers. Considering the complex management of this disease and resistance structure of the pathogen, the present study was conducted in the municipalities of Guarapuava and Palmas in Paraná with the objective of managing the white mold of soybean using straws of winter cereals, such as oat, rye, and triticale. Initially, the three winter cereals were cultivated simultaneously in both the study areas. Straw production, plant height, and shoot fresh and dry weight were evaluated. Subsequently, BMX Apollo soybean was cultivated on cereal straws, and the incidence and severity of white mold were evaluated. In the in vitro experiment, 20 sclerotia covered by a layer of cereal (oat, rye, and triticale) straws were added and carpogenic germination was observed only in the control treatment after 98 days. Regardless of the study site, rye presented greater height and fresh weight than the remaining two cereals. Soybean cultivation on winter cereal straw reduced the incidence and severity of white mold. Cultivation on rye straw reduced mold incidence by 77.7% and 76.6% in Palmas and Guarapuava, respectively.

OBJECTIVE: Coronavirus disease 2019 (COVID-19) is associated with high mortality among hospitalized patients and incurs high costs. Severe acute respiratory syndrome coronavirus 2 infection can trigger both inflammatory and thrombotic processes, and these complications can lead to a poorer prognosis. This study aimed to evaluate the association and temporal trends of D-dimer and C-reactive protein (CRP) levels with the incidence of venous thromboembolism (VTE), hospital mortality, and costs among inpatients with COVID-19. METHODS: Data were extracted from electronic patient records and laboratory databases. Crude and adjusted associations for age, sex, number of comorbidities, Sequential Organ Failure Assessment score at admission, and D-dimer or CRP logistic regression models were used to evaluate associations. RESULTS: Between March and June 2020, COVID-19 was documented in 3,254 inpatients. The D-dimer level ≥4,000 ng/mL fibrinogen equivalent unit (FEU) mortality odds ratio (OR) was 4.48 (adjusted OR: 1.97). The CRP level ≥220 mg/dL OR for death was 7.73 (adjusted OR: 3.93). The D-dimer level ≥4,000 ng/mL FEU VTE OR was 3.96 (adjusted OR: 3.26). The CRP level ≥220 mg/dL OR for VTE was 2.71 (adjusted OR: 1.92). All these analyses were statistically significant (p<0.001). Stratified hospital costs demonstrated a dose-response pattern. Adjusted D-dimer and CRP levels were associated with higher mortality and doubled hospital costs. In the first week, elevated D-dimer levels predicted VTE occurrence and systemic inflammatory harm, while CRP was a hospital mortality predictor. CONCLUSION: D-dimer and CRP levels were associated with higher hospital mortality and a higher incidence of VTE. D-dimer was more strongly associated with VTE, although its discriminative ability was poor, while CRP was a stronger predictor of hospital mortality. Their use outside the usual indications should not be modified and should be discouraged.

Abstract The present study investigated the effects of aerobic physical training on the femoral morphological, densitometric and biomechanical properties in growing male rats subjected to protein-based malnutrition. Four-week-old male Wistar rats were randomized into groups of 10 animals: Control Sedentary (CS), Control Trained (CT), Malnourished Sedentary (MS) and Malnourished Trained (MT). Control and malnourished animals received diets with 12% protein and 6% protein, respectively. The trained groups were submitted to a treadmill running program for 8 weeks. Total proteins and albumin were analyzed in the animals' blood plasma. Histological, densitometric and biomechanical analyzes were performed on the animals' femur. Body mass gain, physical performance, biochemical markers and the femoral morphological, densitometric and biomechanical properties were determined. Exercise tolerance increased in trained groups. Malnourished animals exhibited lower serum protein and albumin levels than controls. Porosity and trabecular bone density were not different between groups. The femoral maximum load, maximum load until fracture, resilience, stiffness, tenacity and densitometric properties were reduced by malnutrition. Physical training associated with malnutrition exacerbated the impairment in the femoral maximum load, maximum load until fracture, bone mineral content and density. Aerobic physical training worsens the damages induced by protein-based malnutrition in the femoral biomechanical and densitometric properties of growing male rats.

The current outbreak of a new strain of coronavirus in Wuhan, People’s Republic of China, has made an impact on the global population. Resources are delivered in order to fight the spreading of the virus; however, the mental health impact of the epidemic must be considered in order to address the overall situation. This outbreak is causing mental health problems such as stress, anxiety, depressive symptoms, insomnia, denial, anger and fear. These mental health problems affect the patients and the general population and also have impact on the attention, understanding and decision-making capacity of medical staff , which could hinder the fight against COVID-19, but they could also have a lasting effect on their overall well-being.

El brote actual de una nueva cepa de coronavirus en Wuhan, República Popular de China, ha tenido un impacto en la población mundial. Se entregan recursos para combatir la propagación del virus; sin embargo, se debe considerar el impacto de la epidemia en la salud mental para abordar la situación general.

RESUMO As potencialidades de uso de UAVs na agricultura são enormes e, com a entrada na era da digitalização das lavouras e da Agricultura 4.0, essa plataforma tem ganhado cada vez mais importância. Levantamento rotineiros de dados em campo podem ser melhorados ou mesmo substituídos por imagens obtidas via UAVs e as aplicações de produtos fitossanitários podem ser otimizados. A altíssima resolução espacial das imagens torna os UAVs atrativos para diversas aplicações que o tradicional sensoriamento via satélite ainda não atendem. Ainda, com o enorme desenvolvimento recente das técnicas e aplicações de ciência dos dados, os UAVs têm posição de destaque para auxiliar o agricultor na tomada de decisão mais eficiente e na viabilização da automação de processos agrícolas. Assim, neste trabalho abordaremos as principais aplicações dos UAVs na agricultura, dividindo o texto em cinco grandes tópicos: Levantamento topográfico, Avaliações fisiológicas, Avaliações biofísicas, Monitoramento de alvos biológicos, e Pulverização de produtos fitossanitários e aplicação de bioinsumos.

ABSTRACT Unmanned Aerial Vehicles (UAVs) have potentially significant application in agriculture and, with the emergence of the digital farming era and Agriculture 4.0, this platform has become increasingly important. UAV imagery may improve or even replace routine data surveys, as well as optimize phytosanitary product application. High-spatial resolution imagery makes UAVs attractive for several applications where traditional satellite sensing is still unsuitable. With the significant recent development of data science techniques, UAVs have a prominent position in assisting farmers for more efficient decision-making and automating agricultural processes. Thus, this work addresses the main agricultural applications of UAVs into five major topics: topographic survey, physiological assessments, biophysical assessments, monitoring of biological targets, and spraying of phytosanitary products and application of bio inputs.

RESUMO O trabalho apresenta o potencial energético de blendas de bagaço de cana-de-açúcar e podas de mangueira e cajueiro. As amostras foram caracterizadas por meio da determinação do poder calorífico superior, densidade, análise imediata (umidade, cinzas, matéria volátil e carbono fixo), análise elementar e termogravimetria. As misturas foram preparadas com diferentes frações em massa. Após avaliação qualitativa e quantitativa das amostras verificou-se quais blendas apresentaram os melhores resultados e, em seguida, os briquetes foram produzidos. As misturas de bagaço de cana:poda de mangueira (frações 50%: 50%), bagaço de cana:poda de cajueiro (frações 50%: 50%) e bagaço de cana:poda de cajueiro:poda de mangueira (frações 50%: 25%: 25%) foram utilizadas na produção dos briquetes. A última parte do trabalho apresenta a diferença entre o potencial energético dos briquetes e do bagaço de cana. A densidade energética dos briquetes de bagaço de cana-de-açúcar e poda de mangueira aumentou de 1,79 para 13,55 (kJ cm-3), em relação ao material não compactado. Os briquetes com poda de cajueiro variaram de 1,97 a 12,75 (kJ cm-3) e os briquetes de bagaço de cana:poda de cajueiro:poda de mangueira variaram de 2,46 a 12,18 (kJ cm-3). O briquete de bagaço de cana apresentou variação de 1,25 para 13,22 (kJ cm-3). A investigação do potencial energético de bioprodutos agrícolas (podas de mangueira e cajueiro) em mistura com bagaço de cana-de-açúcar, apresenta à indústria sucroalcooleira uma nova possibilidade de reutilização de resíduos de biomassa para obtenção de energia.

ABSTRACT The work shows the energy potential of blends of sugarcane bagasse with the mango tree and cashew tree's pruning. The samples were characterized by gross calorific value, density, proximate analysis (moisture, ash, volatile matter and fixed carbon), elemental analysis and thermogravimetry. The blends were prepared with different mass fractions. After evaluation of the samples qualitative and quantitative analyses, it was verified which blends showed the better results and then the briquettes were prepared. The blends of sugarcane bagasse:mango tree pruning (fractions 50%:50%), sugarcane bagasse:cashew tree pruning (fractions 50%:50%), and sugarcane bagasse:cashew tree pruning:mango tree pruning (fractions 50%:25%:25%) were used to the briquettes production. The last part of the work shows the difference between the energy potential of the briquettes and the sugarcane bagasse. The energy density of the briquettes of sugarcane bagasse and mango tree pruning increased from 1.79 to 13.55 (kJ cm-3), in relation to the uncompacted material. The cashew tree pruning's briquettes varied from 1.97 to 12.75 (kJ cm-3), and the briquettes of sugarcane bagasse:cashew tree pruning:mango tree pruning varied from 2.46 to 12.18 (kJ cm-3). The sugarcane bagasse briquette showed a variation of 1.25 to 13.22 (kJ cm-3). The investigation of the energy potential of agricultural bioproducts (mango and cashew tree's pruning) in mixture with sugarcane bagasse presents to the sugar-alcohol industry a new possibility of reuse of biomass waste to obtain of energy.

Abstract Purpose: To perform technically the laparoscopic sleeve gastrectomy (LSG) using a unique Intragastric Single Port (IGSG) in animal swine model, evidencing an effective and safe procedure, optimizing the conventional technique. Methods: IGSG was performed in 4 minipigs, using a percutaneous intragastric single port located in the pre-pyloric region. The gastric stapling of the greater curvature started from the pre-pyloric region towards the angle of His by Endo GIA™ system and the specimen was removed through the single port. In the postoperative day 30, the animals were sacrificed and submitted to autopsy. Results: All procedures were performed without conversion, and all survived 30 days. The mean operative time was 42 min. During the perioperative period no complications were observed during invagination and stapling. No postoperative complications occurred. Post-mortem examination showed no leaks or infectious complications. Conclusion: Intragastric Single Port is a feasible procedure that may be a suitable alternative technique of sleeve gastrectomy for the treatment of morbid obesity.

ABSTRACT Transrectal access still has some unsolved issues such as spatial orientation, infection, access and site closure. This study presents a simple technique to perform transcolonic access with survival in a swine model series. A new technique for NOTES perirectal access to perform retroperitoneoscopy, peritoneoscopy, liver and lymphnode biopsies was performed in 6 pigs, using Totally NOTES technique. The specimens were extracted transanally. The flexible endoscope was inserted through a posterior transmural incision and the retrorectal space. Cultures of bacteria were documented for the retroperitoneal space and intra abdominal cavity after 14 days. Rectal site was closed using non-absorbable sutures. There was no bowel cleansing, nor preoperative fasting. The procedures were performed in 6 pigs through transcolonic natural orifice access using available endoscopic flexible instruments. All animals survived 14 days without complications, and cultures were negative. Histopathologic examination of the rectal closure site showed adequate healing of suture line and no micro abscesses. The results of feasibility and safety of experimental Transcolonic NOTES potentially brings new frontiers and future wider applications for minimally invasive surgery. The treatment of colorectal, abdominal and retroperitoneal diseases through a flexible Perirectal NOTES Access (PNA) is a promising new approach.
