Economic analysis of the robotic approach to inguinal hernia versus laparoscopic: is it sustainable for the healthcare system?

INTRODUCTION: There has been a rapid proliferation of the robotic approach to inguinal hernia, mainly in the United States, as it has shown similar outcomes to the laparoscopic approach but with a significant increase in associated costs. Our objective is to conduct a cost analysis in our setting (Spanish National Health System). MATERIALS AND METHODS: A retrospective single-center comparative study on inguinal hernia repair using a robotic approach versus laparoscopic approach. RESULTS: A total of 98 patients who underwent either robotic or laparoscopic TAPP inguinal hernia repair between October 2021 and July 2023 were analyzed. Out of these 98 patients, 20 (20.4%) were treated with the robotic approach, while 78 (79.6%) underwent the laparoscopic approach. When comparing both approaches, no significant differences were found in terms of complications, recurrences, or readmissions. However, the robotic group exhibited a longer surgical time (86 ± 33.07 min vs. 40 ± 14.46 min, p < 0.001), an extended hospital stays (1.6 ± 0.503 days vs. 1.13 ± 0.727 days, p < 0.007), as well as higher procedural costs (2318.63 ± 205.15 € vs. 356.81 ± 110.14 €, p < 0.001) and total hospitalization costs (3272.48 ± 408.49 € vs. 1048.61 ± 460.06 €, p < 0.001). These results were consistent when performing subgroup analysis for unilateral and bilateral hernias. CONCLUSIONS: The benefits observed in terms of recurrence rates and post-surgical complications do not justify the additional costs incurred by the robotic approach to inguinal hernia within the national public healthcare system. Nevertheless, it represents a simpler way to initiate the robotic learning curve, justifying its use in a training context.

Design and fabrication of a lightweight 3D first surface mirror aluminized by DC magnetron sputtering.

Aluminum thin films were deposited on a 3D prototype employing the direct current magnetron sputtering technique to fabricate a lightweight 3D first surface mirror. Before the aluminizing, the surface of the prototypes was evaluated with interferometry and atomic force microscope (AFM). The thin films were characterized using profilometry, UV-Vis spectroscopy, x-ray diffraction, AFM, x-ray photoelectron spectroscopy (XPS), and scanning electron microscopy. High adherence and homogeneous deposition of the aluminum's thin films were achieved. In addition, the purity of the material was confirmed by XPS analysis.

Timing of umbilical cord occlusion, delayed vs early, in preterm babies: A randomized controlled trial (CODE-P Trial).

INTRODUCTION: Our hypothesis was that delayed cord clamping (DCC) (not earlier than 30 s; at 30-60 s) in premature neonates (born between 26.0 and 32.6 weeks of gestation), as compared with the usual early cord clamping (ECC), significantly reduces the need for blood transfusions and incidence of intraventricular haemorrhage (IVH) without an increased rate of maternal postpartum haemorrhage. MATERIAL AND METHODS: A prospective, open-label, randomized, controlled trial was conducted at Vall d'Hebron Hospital from July 2014 to December 2018. All pregnant women at risk of impending preterm birth (≥26.0-<33.0 weeks of gestation) who were admitted to the obstetrics emergency department were evaluated for eligibility. If they met the eligibility criteria, they were invited to participate in the study and, if they agreed, they signed an informed consent. Patients were randomly assigned to one of two groups: ECC group and DCC group. RESULTS: Our study included a total of 57 patients: 30 in the ECC group and 27 in the DCC group. Due to a lack of funding and low recruitment rates, the study was discontinued in 2018. Maternal characteristics and obstetric outcomes were similar between both groups. The intention-to-treat analysis did not reveal any differences between groups for neonatal red blood cell transfusions, neonatal IVH or maternal postpartum haemorrhage. There were no differences for secondary outcomes. Similarly, no differences were observed in the as-treated analysis. CONCLUSION: The primary and secondary outcomes of our study were not achieved. Therefore, more meta-analysis and trials are needed to evaluate the appropriate timing of cord clamping in preterm birth.

Revisión sistemática de intervenciones de fisioterapia respiratoria y sus efectos en la función pulmonar en pacientes obesos intervenidos de cirugía bariátrica / Systematic review of Respiratory Physiotherapy interventions and their effects on lung function in obese patients operated of bariatric surgery

Introducción La incidencia de obesidad alcanza casi un tercio de la población mundial. En España habrá más de 27 millones de personas con obesidad para 2030, suponiendo una enorme carga socioeconómica, obligando a realizar intervenciones como la cirugía bariátrica (CB) que también tiene sus complicaciones. En los últimos años ha existido un avance de técnicas de fisioterapia respiratoria (FR) por ejemplo, empleando ejercicios respiratorios o utilizando presión positiva (PP). Objetivo Revisar sistemáticamente las intervenciones de FR en CB centrándonos en el tipo de intervención, momento y sus efectos sobre la función pulmonar. Metodología Se realizó la búsqueda en las bases PubMed, CINAHL y PEDro hasta marzo del 2022. Se incluyeron estudios de intervenciones de FR, que midieran la función pulmonar, en contexto pre-posquirúrgico de CB. Se excluyeron los trabajos que no aportaran datos originales, intervención no realizada por fisioterapeutas o que no miden función respiratoria. La calidad metodológica de los estudios se evaluó con la escala PEDro y JBI cheklist for cohort studies. Resultados Fueron incluidos 16 documentos, 20% presentó excelente calidad metodológica y 50% buena. El tamaño muestral varió entre 24 y 148, al igual que la edad (entre 18-60 años) incluso alcanzando 75 años en algún estudio, predominando el género femenino. El tipo de intervenciones (manuales, instrumentales o educacionales), momento de aplicación (pre y posquirúrgicas) y resultados evaluados fueron muy heterogéneos. Conclusiones Existe gran variabilidad de intervenciones de fisioterapia en CB, la mayoría (75%) mejoran la función pulmonar, otras indican falta de eficacia y algunas no indican cambios (AU)

Introduction The incidence of obesity reaches almost a third of the world population. In Spain, there will be more than 27 million people with obesity in 2030. Assuming an enormous socioeconomic burden, forcing interventions such as bariatric surgery, whit their complications. In recent years, there has been an advance in Respiratory Physiotherapy (RP) techniques, for example, using breathing exercises or using positive pressure (PP). Objective To systematically review RP interventions in bariatric surgery, focusing on the type of intervention, timing, and its effects on lung function. Methodology PubMed, CINAHL and PEDro databases were searched until March 2022. RP emergency studies were included, which measured lung function, in the pre-post-surgical context of bariatric surgery. Studies that did not provide original data, intervention not performed by physiotherapists or that did not measure respiratory function were excluded. The methodological quality of studies was evaluated with the PEDro scale and the JBI checklist for cohort studies. Results 16 documents were included, 20% presented excellent methodological quality and 50% good. The sample size varied between 24 and 148 and age (between 18-60 years), even reaching 75 years in some studies, with the female gender predominating. The type of outbreak (manual, instrumental or educational), time of application (pre and post-surgery) and results evaluated were very heterogeneous. Conclusions There is a high variability in physiotherapy interventions used in bariatric surgery, most (75%) improve lung function, others indicate lack of efficacy and some do not indicate changes (AU)

Activity of imipenem/relebactam against Enterobacterales and Pseudomonas aeruginosa in Spain. SMART 2016-2020.

OBJECTIVE: To determine susceptibility to the novel ß-lactam/ß-lactamase inhibitor combination imipenem/relebactam in clinical isolates recovered from intra-abdominal (IAI), urinary (UTI), respiratory (RTI) and bloodstream (BSI) infections in the SMART (Study for Monitoring Antimicrobial Resistance Trends) study in SPAIN during 2016 - 2020. METHODS: Broth microdilution MICs for imipenem/relebactam and comparators were determined by a central laboratory against isolates of Enterobacterales and Pseudomonas aeruginosa. MICs were interpreted using EUCAST-2021 breakpoints. RESULTS: In total, 5,210 Enterobacterales and 1,418 P. aeruginosa clinical isolates were analyzed. Imipenem/relebactam inhibited 98.8% of Enterobacterales. Distinguishing by source of infection susceptibility was 99.1% in BSI, 99.2% in IAI, 97.9% in RTI, and 99.2% in UTI. Of intensive care unit isolates (ICU) 97.4% were susceptible and of non-ICU isolates 99.2% were susceptible. In Enterobacterales, activity against Class A, Class B and Class D carbapenemases was 96.2%, 15.4% and 73.2%, respectively. In P. aeruginosa, imipenem/relebactam was active in 92.2% of isolates. By source of infection it was 94.8% in BSI, 92.9% in IAI, 91.7% in RTI, and 93.1% in UTI. An 88.7% of ICU isolates and 93.6% of non-ICU isolates were susceptible to imipenem/relebactam. Imipenem/relebactam remained active against P. aeruginosa ceftazidime-resistant (76.3%), cefepime-resistant (73.6%), imipenem-resistant (71.5%) and piperacillin-resistant (78.7%) isolates. Of all multidrug-resistant or difficult-to-treat resistance P. aeruginosa isolates, 75.1% and 46.2%, respectively, were susceptible to imipenem/relebactam. CONCLUSIONS: Imipenem/relebactam showed high rates of susceptibility in Enterobacterales and P. aeruginosa isolates from different sources of infection as well as depending on patients' location (ICU or non-ICU scenarios).

Fármacos modificadores de la enfermedad en la esclerosis múltiple durante la lactancia: revisión de la evidencia actual / Disease-modifying drugs in multiple sclerosis during breastfeeding: a review of current evidence

Introducción: La esclerosis múltiple afecta principalmente a mujeres en edad fértil, y el período de gestación y posparto es de especial interés por las peculiaridades que comporta en cuanto a evolución de la enfermedad y por las consecuencias terapéuticas que se derivan. En el período de lactancia materna (LM), la elección de la estrategia de tratamiento debe poner en una balanza, por un lado, los beneficios bien establecidos de la LM para el recién nacido y su madre y, por el otro, el perfil de seguridad y potenciales efectos adversos en el lactante derivados de la exposición a los fármacos modificadores de la enfermedad, por transferencia a través de leche materna. Desarrollo: Se realiza una revisión de la evidencia actual acerca de la seguridad de los fármacos modificadores de la enfermedad disponibles para el tratamiento de la esclerosis múltiple durante el período de LM, y se recogen datos de transferencia de los diferentes fármacos a la leche materna, así como los potenciales efectos adversos descritos en el lactante. Los fármacos considerados de primera elección durante este período son el interferón beta y el acetato de glatiramer. El resto de los fármacos modificadores de la enfermedad no están aceptados para su utilización en el período de LM por ficha técnica. Sin embargo, en los últimos años, se han publicado datos de estudios de práctica clínica y series de casos que indican que algunos de estos fármacos podrían utilizarse con seguridad durante este período. Conclusiones: Teniendo en cuenta los beneficios reconocidos de la LM para la salud tanto de la madre como del lactante, se debe recomendar la LM exclusiva a las pacientes con esclerosis múltiple siempre que sea posible. Es fundamental realizar una evaluación individualizada previa al embarazo y valorar las diferentes opciones de tratamiento en función de cada paciente.(AU)

Introduction: Multiple sclerosis mainly affects women of childbearing age, and the pregnancy and postpartum period is of special interest because of the peculiarities of the disease course and the therapeutic consequences that derive from it. During the period of breastfeeding (BF), the choice of treatment strategy must weigh up the well-established benefits of BF for both the newborn and the mother against the safety profile and potential adverse effects on the infant resulting from exposure to disease-modifying drugs transferred through breast milk. Development: The study reviews the current evidence on the safety of disease-modifying drugs available for the treatment of multiple sclerosis during the BF period, and gathers data on the transfer of the different drugs into breast milk, as well as the potential adverse effects described in the infant. The drugs of first choice during this period are interferon beta and glatiramer acetate. The rest of the disease modifying drugs are not accepted for use in the BF period according to their summary of product characteristics. However, in recent years, data from studies of clinical practice and case series have been published suggesting that some of these drugs could be used safely during this period. Conclusions: Given the recognised health benefits of BF for both mother and infant, exclusive breastfeeding is recommended whenever possible. It is essential to carry out an individualised assessment prior to pregnancy and to evaluate the different treatment options depending on each patient.(AU)

Gabapentin increases the abuse liability of alcohol alone and in combination with oxycodone in participants with co-occurring opioid and alcohol use disorder.

BACKGROUND: People who have co-occurring Alcohol Use Disorder (AUD) and Opioid Use Disorder (OUD) carry a higher risk of adverse outcomes, including drug overdose. Early clinical and preclinical studies suggested that gabapentin may be effective in treating both disorders. The present study was designed to assess the effects of gabapentin on the subjective and physiological effects of oxycodone (OXY) and alcohol (ALC), alone and in combination. METHODS: During an 8-week, inpatient, within-subject, randomized, double-blind, placebo-controlled crossover study, non-treatment seeking participants (N = 13; 12 M/1F; 44.1 ± 3 years of age) with OUD and AUD were maintained on oral morphine (120 mg daily). Under gabapentin (1800 mg/day) and placebo (0 mg/day) maintenance, participants completed nine separate test sessions (three sessions per week) during which they received an oral solution containing 0, 15, or 30 mg/70 kg OXY in combination with 0, 0.5, or 0.75 g/kg ALC. During test sessions, subjective effects and physiological responses were assessed repeatedly on 100-mm visual analog scales (VAS). The primary outcome variable was the VAS rating of drug liking after receiving the drug challenge. RESULTS: Alcohol alone (but not oxycodone alone) produced dose-related increases in several positive subjective responses, including drug liking. Gabapentin significantly increased drug liking when given in combination with ALC and OXY + ALC (p < 0.05). Gabapentin did not clinically compromise respiration or other vital functions. CONCLUSIONS: Gabapentin may increase the abuse liability of ALC and OXY + ALC in those with co-occurring OUD and AUD.

The feasibility of masks and face shields designed by 3D printing makers; some considerations of their use against the COVID-19.

The use of mask and face shield has been established as one of the main preventive measures for the control of COVID 19 spread. In Mexico, as well as in other regions of the world, 3D printing has been employed for the design and production of masks and face shields as personal protective equipment (PPE). These models have been fabricated mainly by the makers, industries, and university communities; therefore, it is necessary to analyze the feasibility of the 3D printed PPE to understand its advantages and limitations. In this work, some characteristics of masks and face shields fabricated by additive manufacturing were studied to explore their viability as protection against flow fluids similar to human sneeze. In the present paper, the PPE was designed, and 3D printed utilizing three types of polylactic acid (PLA) as base material. The morphology and the surface elemental analyses of sectioned samples were analyzed by scanning electron microscopy (SEM) and energy dispersion x-ray spectroscopy (EDS). Showing spacing between printed layers, porous areas, and dispersed copper particles. On the other hand, a computational fluid dynamics (CFD) simulation was carried out, the results demonstrated the importance of using PPE for protection of a possible exposure to a "contaminated" aerosol and human sneeze. Based on the abovementioned results, it is possible to consider the commercial PLA as suitable material for the manufacturing of PPE due to its capability to be disinfected employing isopropanol, ethanol, or commercial disinfectants.

Tríada találgica. Una nueva entidad clínica a partir de una serie de casos / Thalalgic triad. A new clinical entity from a case series

Introducción: El dolor crónico en el talón es un cuadro frecuente en la patología del pie. Este tipo de cuadros no están causados por una sola lesión, sino que es el resultado de la combinación de una serie de cuadros clínicos, especialmente por una neuropatía de Baxter y una fascitis plantar. Desde hace varios años, y tras analizar una serie de casos clínicos, se observa que los pacientes con dolor crónico en el talón cursan con un proceso de fasciosis plantar, edema óseo de calcáneo o síndrome congestivo de calcáneo y neuropatía del nervio de Baxter. A raíz de este hallazgo concluimos en una nueva entidad clínica denominada tríada találgica, la cual no presenta referencias bibliográficas anteriores en la literatura científica. Pacientes y métodos: Se ha llevado a cabo una serie de casos de 10 pacientes a los que se les diagnostica una combinación de 3 patologías, denominada tríada találgica, que cursa con aparición de fasciosis plantar, edema óseo de calcáneo (congestión calcánea) y neuropatía compresiva de Baxter. Cada una de estas patologías se trata de forma independiente con distintas terapias, tales como soportes plantares, infiltraciones, tratamiento farmacológico o cirugía. Resultados: Un total de 10 mujeres con una edad media de 53 años fueron diagnosticadas de fasciosis plantar, edema óseo de calcáneo y neuropatía compresiva de Baxter mediante diferentes pruebas, como la ecografía. Estas pacientes fueron tratadas mediante infiltraciones de colágeno, extracción del líquido sanguinolento del calcáneo, terapia electrolisis percutánea intratisular, soportes plantares, tratamiento farmacológico y ondas de choque. El 40 % de la muestra se encontraba de baja laboral debido al dolor incapacitante de esta tríada y el 10 % en situación de jubilación. Conclusiones: La tríada találgica es una entidad clínica desconocida, con un diagnóstico complejo que combina pruebas complementarias con diagnóstico clínico...(AU)

Introduction: Chronic heel pain is a frequent condition in foot pathology. These types of pictures are not caused by a single injury, but are the result of a combination of a series of clinical pictures, especially Baxter's neuropathy and plantar fasciitis. For several years and after analyzing a series of clinical cases, it has been observed that patients with chronic pain in the heel present with a process of plantar fasciosis, calcaneal bone edema or congestive calcaneal syndrome and Baxter nerve neuropathy. As a result of this finding, we conclude on a new clinical entity called thatalgic triad, which does not present previous bibliographic references in the scientific literature. Patients and methods: A series of cases of 10 patients who were diagnosed with a combination of 3 pathologies, called the thatalgic triad, has been carried out, with the appearance of plantar fasciosis, calcaneal bone edema (calcaneal congestion) and neuropathy Baxter compression. Each of these pathologies is treated independently with different therapies, such as plantar supports, infiltrations, drug treatment or surgery. Results: A total of 10 women with a mean age of 53 years were diagnosed with plantar fasciosis, calcaneal bone edema and Baxter's compressive neuropathy by different tests, such as ultrasound. These patients were treated by collagen infiltrations, removal of bloody fluid from the calcaneus, intratissular percutaneous electrolysis therapy, plantar supports, pharmacological treatment, and shock waves. 40 % of the sample was on sick leave due to the disabling pain of this triad and 10 % were in retirement. Conclusions: The thatalgic triad is an unknown clinical entity with a complex diagnosis that combines complementary tests with clinical diagnosis. Likewise, there are very few bibliographic references on this subject.(AU)

Cirugía del sueño: Definición de una especialidad emergente, propuesta de una clasificación anatomofuncional integral e indicaciones

Resumen Los trastornos respiratorios del sueño (ronquido primario y síndrome de apnea-hipopnea obstructiva del sueño) han sido tratados mediante múltiples modalidades a lo largo de la historia. Sin embargo, la cirugía de la vía aérea superior siempre ha estado presente, dando cabida a la aparición de múltiples técnicas para este fin. El estudio adecuado de los sitios anatómicos de estrechez o colapso de la vía aérea superior y sus contribuyentes (bajo el concepto de topodiagnóstico) y el mejor entendimiento de los mecanismos de acción de los diferentes procedimientos descritos, ha permitido el nacimiento de una nueva disciplina, dedicada al manejo quirúrgico planificado de este grupo de patologías: la cirugía del sueño.

Abstract Sleep-related breathing disorders (primary snoring and obstructive sleep apnea-hypopnea syndrome) have been treated with multiple modalities throughout history. However, upper airway surgery has always been present, giving appearance of multiple techniques for this purpose. The adequate study of the anatomical sites of upper airway narrowness or collapse and its contributors (under the concept of topodiagnosis) and a better understanding of the different procedures, has allowed the birth of a new discipline, dedicated to a planned surgical management for this group of pathologies: sleep surgery.

Estimación de riesgo cardiovascular ateroesclerótico en pacientes adultos sin sospecha de cifras tensionales elevadas / Estimation of aterosclerotic cardiovascular risk in adult patients without a suspicion of having high pressure readings / Estimativa do risco cardiovascular aterosclerótico em pacientes adultos sem suspeita de níveis elevados de tensão arterial

RESUMEN Introducción: Las enfermedades cardiovasculares representan la primera causa de muerte en el mundo. La estimación del Riesgo Cardiovascular (RCV) podría disminuir la carga de la enfermedad y mejorar la calidad de vida de los pacientes. Objetivo: Estimar el RCV en pacientes sin sospecha de cifras tensionales elevadas en una Clínica de Medicina Familiar en la Ciudad de México. Métodos: Estudio transversal descriptivo, participaron 101 pacientes de sexo masculino y femenino, de 40 a 69 años, sin diagnóstico previo de Hipertensión Arterial (HTA), pero que presentaron cifras tensionales altas al momento del estudio. Para diagnosticar HTA se utilizaron los criterios de la Asociación Americana del Corazón-2017. El RCV se evaluó con el ASCVD-Risk Estimator Plus. Resultados: En la muestra la HTA estuvo presente en el 55.4 %, 44.6 % manifestaron presión arterial elevada. Respecto al RCV, 54.4 % presentaron bajo riesgo, 11.8 % riesgo límite, 25.7 % intermedio y 7.9 % alto. Los factores de RCV con mayor prevalencia fueron diabetes mellitus tipo 2 (DM2), sobrepeso, obesidad y elevación de cifras tensionales. Discusión: Un porcentaje importante de participantes presentó RCV en sus diferentes categorías. Se requiere ser más estrictos en los parámetros utilizados para definir la HTA; pues sin intervenciones oportunas las enfermedades cardiovasculares continuarán incrementándose. Conclusión: Cerca de la mitad de los casos presentaron un RCV de límite a alto. Existió alta prevalencia de factores de riesgo individuales como DM2, HTA y dislipidemia. Se deben fortalecer búsquedas intencionadas de pacientes con características similares a las de este estudio para prevenir el desarrollo de enfermedades cardiovasculares.

ABSTRACT Introduction: Cardiovascular diseases are the main cause of death in the world. The estimation of the Cardiovascular Risk (CVR) could both reduce the burden of the illness and improve the quality of life of the patients. Objective: To estimate the CVR in adult patients without a suspicion of having high pressure readings in a Clinic of Family Medicine in Mexico City. Methods: This is a descriptive and transversal study with a sample of 101 male and female patients in the range of 40 to 69 years old, who did not have a previous hypertension diagnosis but who, at the moment of this study, showed high tension readings. The American Heart Association 2017 criteria were used. The cardiovascular risk was assessed using the ASCVD-Risk Estimator Plus. Results: Arterial hypertension readings were found in 55.4 % of the sample. 54.4 % of the sample met the criteria for low risk, 11.8 % for limit risk, 25.7 % for medium risk, and 7.9 % for high risk. The most prevalent factors associated with cardiovascular risk were type 2 diabetes mellitus, overweight, obesity, and hypertension. Discussion: An important percentage of the sample showed cardiovascular risk to some degree, suggesting that perhaps using stricter parameters to define hypertension could prompt more timely interventions. Conclusion: Considering both the high percentage of participants who demonstrated having a cardiovascular risk of concern and the high prevalence of risk factors such as Type 2 Diabetes Mellitus, hypertension, and overweight, timely monitoring interventions should be promoted in order to prevent the development of cardiovascular diseases.

RESUMO Introdução: As doenças cardiovasculares representam a principal causa de morte a nível mundial. A estimativa do risco cardiovascular (RCV) poderia diminuir o peso da doença e melhorar a qualidade de vida dos pacientes. Objetivo: Estimar o RCV em pacientes sem suspeita de tensão arterial elevada em uma Clínica de Medicina Familiar na Cidade do México. Métodos: Um estudo descritivo transversal envolvendo 101 pacientes do sexo masculino e feminino com idades entre os 40 - 69 anos, sem diagnóstico prévio de hipertensão (HTA), mas com tensão arterial elevada no momento do estudo. Os critérios da American Heart Association-2017 foram utilizados para diagnosticar o HTA. O RCV foi avaliado utilizando o ASCVD-Risk Estimator Plus. Resultados: Na amostra, a HTA esteve presente em 55,4 %, 44,6 % reportou tensão arterial elevada. Em relação à RCV, 54,4 % apresentavam baixo risco, 11,8 % risco limite, 25,7 % risco intermédio e 7,9 % alto risco. Os fatores de RCV mais prevalentes foram a diabetes melito tipo 2 (DM2), excesso de peso, obesidade e tensão arterial elevada. Discussão: Uma percentagem significativa de participantes tinha RCV em diferentes categorias. Há necessidade de ser mais rigoroso nos parâmetros utilizados para definir a HTA; sem intervenções atempadas, as doenças cardiovasculares continuarão aumentando. Conclusão: Quase metade dos casos tinham um limite de RCV elevado. Havia uma elevada prevalência de fatores de risco individuais tais como DM2, hipertensão e dislipidemia. A procura intencional de pacientes com características semelhantes às deste estudo deve ser reforçada para prevenir o desenvolvimento de doenças cardiovasculares.

Antimicrobial activity of ceftolozane-tazobactam against Enterobacterales and Pseudomonas aeruginosa recovered during the Study for Monitoring Antimicrobial Resistance Trends (SMART) program in Spain (2016-2018).

OBJECTIVE: To analyse the susceptibility to ceftolozane-tazobactam and comparators in Enterobacterales and Pseudomonas aeruginosa isolates recovered from intraabdominal (IAI), urinary (UTI), respiratory (RTI) and bloodstream infection (BSI) in the SMART (Study for Monitoring Antimicrobial Resistance Trends) study. METHODS: The susceptibility of 5,351 isolates collected in 11 Spanish hospitals (2016-2018) were analysed (EUCAST-2020 criteria) by broth microdilution and were phenotypically studied for the presence of extended-spectrum beta-lactamases (ESBL). Ceftolozane-tazobactam and/or carbapenem resistant isolates were genetically characterized for ESBL and carbapenemases. RESULTS: Escherichia coli was the most frequent pathogen (49.3% IAI, 54.9% UTI, 16.7% RTI and 50% BSI), followed by Klebsiella pneumoniae (11.9%, 19.1%, 13.1% and 15.4%, respectively). P. aeruginosa was isolated in 9.3%, 5.6%, 32% and 9%, respectively. The frequency of isolates with ESBLs (2016-2017) was: 30.5% K. pneumoniae, 8.6% E. coli, 2.3% Klebsiella oxytoca and 0.7% Proteus mirabilis. Ceftolozane-tazobactam was very active against non-ESBL-(99.3% susceptible) and ESBL-(95.2%) producing E. coli being less active against K. pneumoniae (98% and 43.1%, respectively) isolates. CTX-M-15 was the most prevalent ESBL in E. coli (27.5%) and K. pneumoniae (51.9%) frequently associated with OXA-48-like carbapenemase. Overall, 93% of P. aeruginosa isolates were susceptible to ceftolozane-tazobactam, preserving this activity (>75%) in isolates resistant to other beta-lactams except in those resistant to meropenen or ceftazidime-avibactam. GES-5, PER-1, VIM-1/2 were the most prevalent enzymes in isolates resistant to ceftolozane-tazobactam. CONCLUSIONS: Ceftolozane-tazobactam showed high activity rates against isolates recovered in the SMART study although it was affected in K. pneumoniae and P. aeruginosa isolates with ESBL and/or carbapenemases.

Interplay of microbial communities with mineral environments in coralline algae.

Coralline algae are worldwide carbonate builders, considered to be foundational species and biodiversity hotspots. Coralline habitats face increasing pressure from human activities and effects related to Global Change, yet their ecological properties and adaptive responses remain poorly understood. The relationships of the algal microbiota with the mineral bioconstructions, as well as plasticity and resilience of coralline holobionts in a changing environment, are of particular interest. In the Gulf of California, Neogoniolithon trichotomum (Rhodophyta) is the main carbonate builder in tidal pools. We performed a multi-disciplinary assessment of the N. trichotomum microstructure using XRD, SEM microscopy and SR-FTIR spectromicroscopy. In the algal perithallus, magnesium-calcite and aragonite were spatially segregated and embedded in a polysaccharide matrix (rich in sulfated polysaccharides). Mg-calcites (18-19 mol% Mg) were the main mineral components of the thallus overall, followed by iron carbonates related to dolomite (ankerite) and siderite. Minerals of late evaporitic sequences (sylvite and bischofite) were also present, suggesting potential halophilic microenvironments within the algal thalli. The diverse set of abundant halophilic, halotolerant and oligotrophic taxa, whose abundance increase in the summer, further suggests this condition. We created an integrated model, based on environmental parameters and the microbiota distribution, that identified temperature and nutrient availability (particularly nitrate and silicate) as the main parameters related to specific taxa patterns. Among these, Hahella, Granulossicoccus, Ferrimonas, Spongiibacteraceae and cyanobacterial Xenococcaceae and Nostocaceae change significantly between seasons. These bacterial components might play relevant roles in algal plasticity and adaptive responses to a changing environment. This study contributes to the understanding of the interplay of the prokaryotic microbiota with the mineral microenvironments of coralline algae. Because of their carbonates with potential resistance to dissolution in a higher pCO2 world and their seasonally dynamic bacteria, coralline algae are relevant targets to study coastal resilience and carbonated systems responses to changing environments.

Faringoplastía de reposición con suturas barbadas como tratamiento quirúrgico en pacientes con síndrome de apnea-hipopnea obstructiva del sueño / Barbed sutures reposition pharyngoplasty as surgical treatment in obstructive sleep apnea-hypopnea syndrome

INTRODUCCIÓN: La planificación de cirugías para el manejo del síndrome de apneahipopnea obstructiva del sueño (SAHOS) ha incrementado su precisión desde la introducción de la endoscopía del sueño inducido por fármacos (DISE). OBJETIVO: Evaluar la técnica de faringoplastía de reposición con suturas barbadas (BRP) para el colapso velofaríngeo y/o de paredes laterales orofaríngeas evaluado mediante DISE en pacientes con SAHOS. MATERIAL Y MÉTODO: Ochenta y ocho pacientes fueron evaluados para cirugía mediante antropometría, escala de somnolencia de Epworth (ESS) y poligrafía respiratoria. Veinte y seis de 88 pacientes fueron seleccionados. De los 26, 14 accedieron al tratamiento quirúrgico, el que se seleccionó en base a la DISE. En todos los casos, se realizó BRP. RESULTADOS: A los 3 meses de la cirugía hubo mejoría en 10/14 pacientes (criterios de Sher, disminución del índice de apnea-hipoapnea a <20 o 50% del basal). La ESS bajó en promedio de 12 a 5 puntos (p <0,05). No se reportaron incidentes en el posoperatorio y no han ocurrido eventos adversos. CONCLUSIÓN: La técnica de BRP es una técnica sencilla y útil para la expansión anterior y lateral del paladar blando y orofaringe, con una tasa de éxito similar en esta cohorte a la reportada internacionalmente.

INTRODUCTION: Surgical planning for the management of obstructive sleep apneahypopnea syndrome (OSAHS) has changed since the introduction of drug induced sleep endoscopy (DISE). AIM: To evaluate the technique of barbed sutures reposition pharyngoplasty (BRP) for velopharyngeal collapse and/or oropharyngeal lateral walls after DISE evaluation in OSAHS patients. MATERIAL AND METHOD: 88 patients were evaluated for surgery by anthropometry, Epworth sleepiness scale (ESS) and respiratory polygraphy. 26 of 88 patients were selected. Of the 26, 14 agreed to surgical treatment, which was selected on DISE findings. In all cases, BRP was performed. RESULTS: Three months after surgery there was improvement in 10/14 patients (Sher criteria, apnea-hypopnea index reduction at <20 or 50% of baseline). The ESS improved on average 12 to 5 (p <0.05). No incidents were reported in the post-operative period and no adverse events were reported. CONCLUSION: The BRP technique is a simple and useful technique for the anterior and lateral expansion of the soft palate and oropharynx, with a similar success rate in this cohort to that internationally reported.

Comparison of oncological outcomes after open and laparoscopic re-resection of incidental gallbladder cancer.

BACKGROUND: The safety and oncological efficacy of laparoscopic re-resection of incidental gallbladder cancer have not been studied. This study aimed to compare laparoscopic with open re-resection of incidentally discovered gallbladder cancer while minimizing selection bias. METHODS: This was a multicentre retrospective observational cohort study of patients with incidental gallbladder cancer who underwent re-resection with curative intent at four centres between 2000 and 2017. Overall survival (OS) and recurrence-free survival (RFS) were analysed by intention to treat. Inverse probability of surgery treatment weighting using propensity scoring was undertaken. RESULTS: A total of 255 patients underwent re-resection (190 open, 65 laparoscopic). Nineteen laparoscopic procedures were converted to open operation. Surgery before 2011 was the only factor associated with conversion. Duration of hospital stay was shorter after laparoscopic re-resection (median 4 versus 6 days; P < 0·001). Three-year OS rates for laparoscopic and open re-resection were 87 and 62 per cent respectively (P = 0·502). Independent predictors of worse OS were residual cancer found at re-resection (hazard ratio (HR) 1·91, 95 per cent c.i. 1·17 to 3·11), blood loss of at least 500 ml (HR 1·83, 1·23 to 2·74) and at least four positive nodes (HR 3·11, 1·46 to 6·65). In competing-risks analysis, the RFS incidence was higher for laparoscopic re-resection (P = 0·038), but OS did not differ between groups. Independent predictors of worse RFS were one to three positive nodes (HR 2·16, 1·29 to 3·60), at least four positive nodes (HR 4·39, 1·96 to 9·82) and residual cancer (HR 2·42, 1·46 to 4·00). CONCLUSION: Laparoscopic re-resection for selected patients with incidental gallbladder cancer is oncologically non-inferior to an open approach. Dissemination of advanced laparoscopic skills and timely referral of patients with incidental gallbladder cancer to specialized centres may allow more patients to benefit from this operation.

ANTECEDENTES: No se conoce la seguridad y la eficacia oncológica de la re-resección laparoscópica del cáncer incidental de vesícula biliar. Este estudio tiene como objetivo comparar las re-resecciones del cáncer incidental de vesícula biliar por vía laparoscópica y vía abierta, minimizando el sesgo de selección. MÉTODOS: Estudio de cohortes observacional, retrospectivo y multicéntrico de pacientes con cáncer incidental de vesícula biliar que se sometieron a una re-resección con intención curativa en 4 centros entre 2000 y 2017. Se analizó la supervivencia global (overall survival, OS) y la supervivencia libre de recidiva (recurrence free survival, RFS) según intención de tratamiento. Se calculó la probabilidad inversa de la ponderación del tratamiento quirúrgico utilizando puntuación de propensión. RESULTADOS: Se incluyeron 255 pacientes con re-resección (190 por vía abierta y 65 por vía laparoscópica). Se convirtieron 19 pacientes del grupo laparoscópico. El único factor relacionado con la conversión fue la realización de la cirugía antes de año 2011. La mediana de la estancia hospitalaria fue más corta tras la re-resección laparoscópica (4 versus 6 días; P < 0,001). La OS a tres años fue del 87% y del 62% (P = 0,502) para las re-resecciones laparoscópicas y abiertas, respectivamente). Los factores predictivos independientes relacionados con una peor OS fueron el hallazgo de cáncer residual en el momento de la re-resección (cociente de riesgos instantáneos, hazard ratio, HR 1,91; i.c. del 95% 1,17-3,11), una pérdida hemática > 500 ml (HR 1,83; i.c. del 95% 1,23-2,74) y la presencia de ≥ 4 ganglios positivos (HR 3,11; i.c. del 95% 1,46-6,65). En el análisis de riesgo competitivo, la RFS fue mayor para la resección laparoscópica (P = 0,038), pero no hubo diferencias en la OS entre ambos grupos. Los factores predictivos independientes de peor RFS fueron la detección de 1-3 ganglios positivos (HR 2,16; i.c. del 95% 1,29-3,60), ≥ 4 ganglio positivos (HR 4,39; i.c. del 95% 1,96-9,82) y el cáncer residual (HR 2,42; i.c. de 95% 1,46-4,0). CONCLUSIÓN: En pacientes seleccionados, los resultados oncológicos de la re-resección laparoscópica de un cáncer incidental de vesícula biliar no son inferiores a los que se obtienen por vía abierta. Una mayor difusión de las técnicas laparoscópicas avanzadas y una oportuna derivación de los pacientes con cáncer de vesícula biliar incidental a centros especializados podrían permitir que un mayor número de pacientes se beneficiaran de este abordaje.

Monitoring the antimicrobial susceptibility of Gram-negative organisms involved in intraabdominal and urinary tract infections recovered during the SMART study (Spain, 2016 and 2017).

OBJECTIVE: Continuous antimicrobial resistance surveillance is recommended by Public Health authorities. We up-dated data from the SMART (Study for Monitoring Antimicrobial Resistance Trends) surveillance study in Spain. METHODS: The antimicrobial susceptibility data and extended-spectrum beta-lactamase (ESBL) production in isolates recovered from intra-abdominal (IAI) (n=1,429) and urinary tract (UTI) (n=937) infections during the 2016- 2017 SMART study in 10 Spanish hospitals were analysed. RESULTS: Escherichia coli was the most frequently microorganism isolated (48.3% and 53.7%) followed by Klebsiella spp. (11.5% and 21.9%) in IAIs and UTIs, respectively. Figures for Pseudomonas aeruginosa were 9.0% and 6.1%, being more frequently recovered from patients with nosocomial infections. Overall, 9.9% (IAI) and 14.0% (UTI) of E. coli, Klebsiella spp. and Proteus mirabilis isolates were ESBL-producers, being Klebsiella pneumoniae (34.5%) from UTI of nosocomial origin the most frequent. ESBL-producers were higher in patients >60 years in both IAIs and UTIs. As in previous years, amikacin (96.3%-100% susceptibility), ertapenem (84.2%-100%) and imipenem (70.3%- 100%) were the most active antimicrobials tested among Enterobacterales species. The activity of amoxicillin-clavulanic, piperacillin-tazobactam, and ciprofloxacin susceptibility was lower, particularly among ESBL-producers. Ertapenem susceptibility (88.9%-100%) was retained in ESBL-E. coli isolates that were resistant to these antimicrobials but decreased (28.6%-100%) in similar isolates of K. pneumoniae. CONCLUSIONS: Continuous antimicrobial resistance surveillance from the SMART study reveals overall maintenance of ESBL-producers in Spain, although with higher presence in isolates from UTIs than from IAIs. Moreover, ertapenem activity was high in E. coli irrespective of ESBL production but decreased in K. pneumoniae, particularly among ESBL-producers.

Liver Transplant From Controlled Cardiac Death Donors Using Normothermic Regional Perfusion: Comparison With Liver Transplants From Brain Dead Donors.

BACKGROUND: Liver transplantation from donors after either controlled or uncontrolled cardiac death (DCD) is associated with considerable rates of primary nonfunction (PNF) and ischemic cholangiopathy (IC). Normothermic regional perfusion (NRP) could significantly reduce such rates. METHODS: Retrospective study to analyze short-term (mortality, PNF, vascular complications) and long-term (IC, survival) complications in 11 liver transplants from controlled DCDs using NRP with extracorporeal membrane oxygenation (ECMO) (group 1). They were compared with 51 patients transplanted with grafts from donors after brain death (DBD) (group 2). Mean recipient age, sex, and Model for End-stage Liver Disease (MELD) score were not significantly different. RESULTS: In group 1, mean functional warm ischemia time was 15.8 (range, 7-40) minutes and 94.1 (range, 20-150) minutes on NRP. The ischemic damage was minimal, as shown by the slight alanine aminotransferase (ALT) and aspartate aminotransferase (AST) rises in the donor serum after 1 hour on NRP and similar rises 24 hours after transplantation in both groups. No patient had IC or acute renal failure. No significant difference was found between the groups for vascular or biliary complications. One group 1 patient had PNF (9.1%), resulting in death. Overall retransplantation and in-hospital death rates were 8.1% and 4.8%, respectively, with no significant difference between groups. Estimated mean survival was 24.6 (95% confidence interval [CI], 20.2-29.1) months in group 1 and 32.3 (95% CI, 30.4-34.2) months in group 2 (not a statistically significant difference). CONCLUSION: In our experience, liver transplants from controlled DCDs using NRP with ECMO is associated with a low risk of PNF and IC, with short- and long-term results comparable to those in DBD transplants.

A Soliton-Based Model Mimics the Arterial Pulse Propagation as Much as a Widely Used 1D Model.

INTRODUCTION: A comparison among two blood pressure pulse propagation models has made in this work. One of them is a traditional model based upon the Navier Stockes equations in one spatial dimension, the one along the direction of the arteries (from here NS1D), the other is based the concept of soliton propagation using the Korteweg De Vries equation (named KdV). METHODS: The arterial three is assumed a long successive connection of serial segments of arteries, at the inlet of the network (close up to the aorta), an acquired pulse, in vivo, wave is imposed. The computed of the peripheral blood pressure at the outlet of the final segment constitutes the output of the model (near the radial artery). RESULTS: Both models reproduced main characteristics of the measured radial wave pressure for the same input. CONCLUSION: The results show that the model KdV have many conceptual and computer benefits than the usual model NS1D that constitutes an interesting pathway for the scientific research.
