Environmental stressor assessment of hydrocarbonoclastic bacteria biofilms from a marine oil spill.

The environmental and economic impact of an oil spill can be significant. Biotechnologies applied during a marine oil spill involve bioaugmentation with immobilised or encapsulated indigenous hydrocarbonoclastic species selected under laboratory conditions to improve degradation rates. The environmental factors that act as stressors and impact the effectiveness of hydrocarbon removal are one of the challenges associated with these applications. Understanding how native microbes react to environmental stresses is necessary for effective bioaugmentation. Herein, Micrococcus luteus and M. yunnanensis isolated from a marine oil spill mooring system showed hydrocarbonoclastic activity on Maya crude oil in a short time by means of total petroleum hydrocarbons (TPH) at 144 h: M. luteus up to 98.79 % and M. yunnanensis 97.77 % removal. The assessment of Micrococcus biofilms at different temperature (30 °C and 50 °C), pH (5, 6, 7, 8, 9), salinity (30, 50, 60, 70, 80 g/L), and crude oil concentration (1, 5, 15, 25, 35 %) showed different response to the stressors depending on the strain. According to response surface analysis, the main effect was temperature > salinity > hydrocarbon concentration. The hydrocarbonoclastic biofilm architecture was characterised using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Subtle but significant differences were observed: pili in M. luteus by SEM and the topographical differences measured by AFM Power Spectral Density (PSD) analysis, roughness was higher in M. luteus than in M. yunnanensis. In all three domains of life, the Universal Stress Protein (Usp) is crucial for stress adaptation. Herein, the uspA gene expression was analysed in Micrococcus biofilm under environmental stressors. The uspA expression increased up to 2.5-fold in M. luteus biofilms at 30 °C, and 1.3-fold at 50 °C. The highest uspA expression was recorded in M. yunnanensis biofilms at 50 °C with 2.5 and 3-fold with salinities of 50, 60, and 80 g/L at hydrocarbon concentrations of 15, 25, and 35 %. M. yunnanensis biofilms showed greater resilience than M. luteus biofilms when exposed to harsh environmental stressors. M. yunnanensis biofilms were thicker than M. luteus biofilms. Both biofilm responses to environmental stressors through uspA gene expression were consistent with the behaviours observed in the response surface analyses. The uspA gene is a suitable biomarker for assessing environmental stressors of potential microorganisms for bioremediation of marine oil spills and for biosensing the ecophysiological status of native microbiota in a marine petroleum environment.

Achievements and challenges in the health of Mexican women, 1990 and 2019: ecological analysis based on the global burden of disease data.

OBJECTIVES: To describe the burden and causes of disease in Mexican women in 1990 and 2019, based on the data disaggregation by age groups and states. Also, to evaluate the relationship of years of healthy life lost with the Socio-demographic Index (SDI) and with the Healthcare Access and Quality (HAQ) Index. STUDY DESIGN: This was an ecological descriptive study. METHODS: Based on the Global Burden of Disease, Injuries, and Risk Factors Study study, the age-standardized and age-specific rates for mortality, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life years (DALYs) were reported. RESULTS: At the national level, the all-cause age-standardized rates for Mexican women decreased in mortality -28.8%; YLLs -39.8%; YLDs -1.3%; and DALYs -26.2%. For 2019, the indicators analyzed had the worst performances in Chiapas and Chihuahua, while women in Sinaloa had the lowest age-standardized rates. In 1990, it is worth noting that there was a remarkable presence of CDs, mainly in YLLs. In all age groups, diabetes mellitus was the leading cause of DALYs in Mexico's 32 states, followed by CKD (in 24 states), and ischemic heart disease (in 18 states). In both 1990 and 2019, a negative and statistically significant correlation between DALYs and the HAQ Index was evident. The correlation between DALYs and the SDI was only significant in 1990. CONCLUSION: In the last 30 years, the burden of disease on Mexican women has undergone substantial changes that reflect progress in the improvement of their health conditions. However, the current scenario is complex because the convergence of communicable diseases, non-communicable diseases, and injuries is evident, which implies important challenges that must be addressed as soon as possible.

A new technique in the treatment of intestinal malrotation. / Una nueva técnica en el tratamiento de la malrotación intestinal.

INTRODUCTION: Intestinal malrotation is a congenital pathology with potentially catastrophic complications, such as volvulus, whose treatment has barely not changed in nearly 100 years (Ladd's procedure). Dr. Abu-Elmagd recently described a new technique that was applied in one of our patients. CLINICAL CASE: 12-year-old boy who had undergone Ladd's procedure as a result of intestinal volvulus secondary to malrotation when he was 2 days old. He had subocclusion and eventually obstruction, with intestinal volvulus compatible imaging. Intraoperative findings: duodenal subocclusion, volvulus and lymphangiectasias. Kareem's procedure: bowel positioning in normal rotation, duodenopexy (duodenal C posterior to the mesenteric vessels), formation of neo-Treitz, and fixation of the cecum, the ascending colon, and the mesenteric root. The patient was discharged on postoperative day 6 and remains asymptomatic after 1 year of follow-up. DISCUSSION: Kareem's procedure is a safe and effective malrotation repair technique. It can replace Ladd's procedure as it reduces the risk of re-volvulation and improves digestive symptoms.

INTRODUCCION: La malrotación intestinal es una patología congénita con complicaciones potencialmente catastróficas, destacando el vólvulo, cuyo tratamiento no ha variado significativamente en casi 100 años (procedimiento de Ladd). Recientemente el Dr. Abu-Elmagd describió una técnica que hemos aplicado en un paciente. CASO CLINICO: Varón de 12 años, intervenido con 2 días de vida por vólvulo intestinal secundario a malrotación realizándose procedimiento de Ladd. Presenta cuadros suboclusivos y finalmente obstructivo con imágenes compatibles con vólvulo intestinal. Hallazgos intraoperatorios: suboclusión duodenal, vólvulo y linfangiectasias. Procedimiento de Kareem: posicionando intestino en normorotación, duodenopexia (C duodenal posterior a vasos mesentéricos), formación de neoTreitz, fijación de ciego, colon ascendente y raíz mesentérica. Alta hospitalaria al 6º día postoperatorio, asintomático en 1 año de seguimiento. COMENTARIOS: El procedimiento de Kareem es una técnica segura y efectiva que corrige la malrotación, pudiendo reemplazar al procedimiento de Ladd al disminuir el riesgo de revolvulación y mejorar síntomas digestivos.

El bloqueo del hematoma no es suficiente como método de anestesia en la reducción de fracturas desplazadas de radio distal / The hematoma block is not enough as method of anesthesia in reduction of displaced distal radius fractures

Antecedentes y objetivo: Dos de cada tres fracturas de muñeca están desplazadas pero la mayoría pueden tratarse de forma conservadora tras una reducción cerrada. El dolor que refieren los pacientes durante la reducción cerrada de estas fracturas es variable y el mejor método para controlarlo no está bien establecido. El objetivo de este estudio fue evaluar el dolor durante la reducción cerrada de fracturas de radio distal tras utilizar el bloqueo del hematoma como método anestésico. Material y método: Estudio clínico transversal que incluyó a todos los pacientes que presentaron una fractura aguda de radio distal que requirió reducción cerrada e inmovilización durante un periodo de seis meses en dos Hospitales Universitarios. Se registraron datos demográficos, clasificación de la fractura, dolor percibido mediante una escala visual analógica en diferentes momentos de la reducción y complicaciones. Resultados: Se incluyeron 94 pacientes consecutivos. La edad media fue de 61 años. La puntuación media del dolor en la evaluación inicial fue de seis puntos. Tras realizar el bloqueo del hematoma, el dolor percibido durante la maniobra de reducción descendió a 5,1 puntos en la muñeca, pero aumentó a 7,3 puntos en los dedos. El dolor disminuyó a 4,9 puntos durante la colocación del yeso y alcanzó 1,4 puntos tras la colocación del cabestrillo. El dolor referido fue mayor en las mujeres en todos los momentos. No hubo diferencias significativas según el tipo de fractura. No se observaron complicaciones neurológicas ni cutáneas. Conclusiones: El bloqueo del hematoma es un método solo ligeramente efectivo para reducir el dolor en la muñeca durante la reducción cerrada de las fracturas de muñeca. Esta técnica disminuye ligeramente el dolor percibido en la muñeca y no reduce el dolor en los dedos. Otros métodos de reducción u otras técnicas analgésicas pueden ser opciones más efectivas.(AU)

Background: Two out of three wrist fractures seen in the emergency are displaced but most can be treated conservatively after closed reduction. Patient-reported pain during closed reduction of distal radius fractures varies widely and the best method to decrease the perceived pain has not been well established. The purpose of this study was to assess the pain during closed reduction of distal radius fractures after using the hematoma block as method of anaesthesia. Patients and methods: Cross-sectional clinical study including all patients who presented an acute fracture of the distal radius requiring closed reduction and immobilization during a six-month period in two University Hospitals. Demographic data, fracture classification, perceived pain using a visual analog scale at different times of reduction and complications were registered. Results: Ninety-four consecutive patients were included. Mean age was 61 years. Mean pain score at initial assessment was 6 points. After the hematoma block, the perceived pain during the reduction manoeuvre improved to 5.1 points at the wrist, but increased to 7.3 points at the fingers. Pain decreased to 4.9 points during cast placement and reached 1.4 point after sling placement. The reported pain was higher in women at all times. There were no significant differences according to the according to the type of fracture. No neurological or skin complications were observed. Conclusions: The hematoma block is only a mild effective method to reduce the wrist pain during closed reduction of distal radius fractures. This technique decreases slightly the perceived pain in the wrist and does not reduce the pain in the fingers. Other reduction methods or other analgesic techniques may be more effective options.(AU)

Detection of blaCTX-M-15 in an integrative and conjugative element in four extensively drug-resistant Haemophilus parainfluenzae strains causing urethritis.

Haemophilus parainfluenzae is a commensal organism with rising numbers of multidrug-resistant (MDR) strains. This pathogen is of increasing clinical relevance in urogenital infection. The aim of this work was to identify and characterise the molecular mechanisms of resistance associated with four cephalosporin-resistant H. parainfluenzae strains collected from patients with urethritis. Antimicrobial resistance was determined by microdilution following European Committee on Antimicrobial Susceptibility Testing criteria. Strains were then analysed by whole-genome sequencing to determine clonal relationship and the molecular basis of antimicrobial resistance. Finally, a phylogenetic analysis was performed on all urogenital MDR strains of H. parainfluenzae previously isolated in our hospital. All strains were resistant to ß-lactams, macrolides, tetracycline, fluoroquinolones, chloramphenicol, cotrimoxazole, and aminoglycosides. The resistance profile was compatible with the presence of an extended-spectrum ß-lactamase (ESBL). Whole-genome sequencing detected blaCTX-M-15 that conferred high minimum inhibitory concentrations to cephalosporins in two novel integrative and conjugative elements (ICEHpaHUB6 and ICEHpaHUB7) that also harboured a blaTEM-1 ß-lactamase. This study shows a novel blaCTX-M-15 ESBL carried in an integrative conjugative element in four extensively drug-resistant H. parainfluenzae strains. This resistance determinant could be transmitted to other sexually transmitted pathogens and this is a cause for concern.

Prueba de volumen en el quirófano: subestudio planificado del estudio observacional Fluid Day / Fluid challenges in operating room: A planned sub study of the Fluid Day observational study

Antecedentes: La administración intraoperatoria de fluidos es una intervención ubicua en los pacientes quirúrgicos. Pero la administración inadecuada de fluidos puede llevar a malos resultados postoperatorios. La prueba de volumen (PV), dentro o fuera de la denominada fluidoterapia guiada por objetivos, permite probar el sistema cardiovascular y la necesidad de administración adicional de fluidos. Nuestro objetivo primario fue evaluar el modo en que el anestesiólogo realiza la PV en el quirófano en términos de tipo, volumen, variables utilizadas para impulsar la PV, y comparar la proporción de pacientes que recibieron administración adicional de fluidos basada en la respuesta a la PV. Métodos: Se trata de un subestudio planificado de un estudio observacional realizado en 131 centros en España, en pacientes sometidos a cirugía. Resultados: En el estudio se incluyeron y analizaron 396 pacientes. La cantidad media [rango intercuartílico] de fluidos administrados durante la PV fue de 250ml (200-400). La principal indicación de la PV fue el descenso de la presión arterial sistólica en 246 casos (62,2%). La segunda indicación fue el descenso de la presión arterial media (54,4%). Se utilizó el gasto cardiaco en 30 pacientes (7,58%), y la variación del volumen sistólico en 29 de entre 385 casos (7,32%). La respuesta a la PV inicial no tuvo impacto a la hora de prescribir administración adicional de fluidos. Conclusiones: La indicación y la evaluación actuales de la PV en los pacientes quirúrgicos son altamente variables. La predicción de la receptividad a los fluidos no se utiliza rutinariamente, evaluándose a menudo las variables no adecuadas para valorar la respuesta hemodinámica a la PV, pudiendo causar efectos perjudiciales.(AU)

Background: Intraoperative fluid administration is a ubiquitous intervention in surgical patients. But inadequate fluid administration may lead to poor postoperative outcomes. Fluid challenges (FCs), in or outside the so-called goal-directed fluid therapy, allows testing the cardiovascular system and the need for further fluid administration. Our primary aim was to evaluate how anesthesiologists conduct FCs in the operating room in terms of type, volume, variables used to trigger a FC and to compare the proportion of patients receiving further fluid administration based on the response to the FC. Methods: This was a planned substudy of an observational study conducted in 131 centers in Spain in patients undergoing surgery. Results: A total of 396 patients were enrolled and analyzed in the study. The median [interquartile range] amount of fluid given during a FC was 250mL (200-400). The main indication for FC was a decrease in systolic arterial pressure in 246 cases (62.2%). The second was a decrease in mean arterial pressure (54.4%). Cardiac output was used in 30 patients (7.58%), while stroke volume variation in 29 of 385 cases (7.32%). The response to the initial FC did not have an impact when prescribing further fluid administration. Conclusions: The current indication and evaluation of FC in surgical patients is highly variable. Prediction of fluid responsiveness is not routinely used, and inappropriate variables are frequently evaluated for assessing the hemodynamic response to FC, which may result in deleterious effects.(AU)

Single nucleotide polymorphisms in ADAM17, IL23R and SLCO1C1 genes protect against infliximab failure in adults with Crohn's disease.

BACKGROUND: To predict primary failure of infliximab (IFX) therapy in Crohn's disease (CD) and to identify patients who maintain long-term effectiveness to IFX is currently not feasible. Some genetic variations are proposed as potential biomarkers. AIM: We assessed a set of single nucleotide polymorphisms (SNPs) in genes related to the IFX mechanism of action and the presence of HLA-DQA1 * 05 allele on the primary response and long-term durability in CD patients. METHODS: A multi-centre cross-sectional study of IFX-exposed adult patients with CD was undertaken. Treatment persistence and time to failure were co-primary endpoints. DNA from the 131 patients was genotyped. Association between SNPs and clinical variables with IFX persistence was assessed. RESULTS: Failure to IFX was documented in 65 (49.6%) out of 131 patients. IFX persistence was associated either with carrying the TT genotype in ADAM17 rs10929587 (ORa=0.2; 95%CI=0.1-0.8; p = 0.021), or the CC genotype in SLCO1C1 rs3794271 (ORa=0.2; 95%CI=0.1-0.7; p = 0.008), according to multivariate logistic regression. In contrast, previous bowel resection increased the risk of IFX failure (ORa=2.8; 95%CI=1.1-7.3; p = 0.025). Cox regression analysis confirmed these findings and also identified IL23R rs10489629-TT (HRa 0.41; 95%CI=0.22-0.75; p = 0.004) and concomitant immunosuppressants (HRa 0.46; 95%CI=0.27-0.77; p = 0.003) as protection from IFX failure. However, no association between HLA-DQA1 * 05 allele and persistence of IFX therapy was found, with similar failure rates among carriers and non-carriers (52.8% vs. 47.4%, respectively; p = 0.544). CONCLUSIONS: SNPs rs10929587-TT in ADAM17, rs10489629-TT in IL23R and rs3794271-CC in SLCO1C1, together with no previous bowel surgery and concomitant immunosuppression, were identified as protection from failure to IFX.

Infiltración comisural dorsal en el tratamiento del pulgar y los dedos en resorte. Estudio de una cohorte prospectiva / Out-of-sheath corticosteroid injections through the dorsal webspace for trigger finger and trigger thumb. A prospective cohort study

Antecedentes y objetivo: Las infiltraciones de corticoides son efectivas en el tratamiento de los dedos en gatillo pero el dolor percibido por el paciente durante la inyección es un efecto acompañante siempre presente. El objetivo de este estudio fue evaluar la efectividad y el dolor percibido durante una infiltración corticoidea depositada fuera de la vaina tendinosa utilizando la técnica comisural dorsal. Material y método: Se incluyeron 126 pacientes consecutivos. Se realizó una infiltración esteroidea subcutánea (fuera de la vaina) a través de la comisura dorsal. En los casos en que los signos o síntomas persistieron, se ofreció una segunda infiltración. Se registró el dolor percibido durante la infiltración mediante la escala visual analógica, el cuestionario DASH antes del tratamiento y al final de seguimiento, la tasa de éxito y las complicaciones. Resultados: Fueron 86 mujeres y 40 hombres con una edad media de 61 años. La puntuación media del dolor durante la infiltración fue de 3,8. Doce pacientes se perdieron durante el seguimiento. El éxito global fue del 68% y el éxito tras una única inyección fue del 54%. El mejor resultado se obtuvo en el dedo anular. Los pacientes que no habían sido operados previamente del síndrome del túnel carpiano respondieron mejor. No se objetivaron complicaciones. Conclusiones: La infiltración esteroidea fuera de la vaina tendinosa y utilizando la técnica comisural dorsal es efectiva y segura en el tratamiento de los dedos en resorte. Parece ser menos dolorosa que los resultados publicados para la técnica palmar sobre la línea media, aunque esto debe evaluarse en un estudio diseñado para ello.(AU)

Background and objective: Steroid injections are effective in the treatment of trigger digits but the pain during the injection is an always-present accompanying effect. The aim of this study was to assess the effectiveness and perceived pain during an out-of-sheath corticosteroid injection through the dorsal webspace in the treatment of trigger digits. Material and method: A total of 126 consecutive patients were included. A subcutaneous (out-of-sheath) corticosteroid injection was performed through the dorsal webspace in all digits. In cases where signs or symptoms persisted, a second injection was offered. Visual analog scale for pain during the injection, DASH questionnaire, success rate and complications were collected. Results: There were 86 women and 40 men with a mean age of 61 years. The mean visual analog scale for pain during the injection was 3.8. Twelve patients were lost to follow-up. The overall success was 68% and success after a single injection was 54%. The best result was achieved on the ring finger. Patients who were not previously operated on carpal tunnel syndrome responded better. No complications were noted. Conclusions: The extra-sheath corticosteroid injection through the dorsal webspace is effective and safe. It seems to be less painful than the reported scores for the palmar midline technique although it should be assessed in a comparative study.(AU)

El éxito global fue del 68% y el éxito tras una única inyección fue del 54%. El mejor resultado se obtuvo en el dedo anular. Los pacientes que no habían sido operados previamente del síndrome del túnel carpiano respondieron mejor. No se objetivaron complicaciones. Conclusiones: La infiltración esteroidea fuera de la vaina tendinosa y utilizando la técnica comisural dorsal es efectiva y segura en el tratamiento de los dedos en resorte. Parece ser menos dolorosa que los resultados publicados para la técnica palmar sobre la línea media, aunque esto debe evaluarse en un estudio diseñado para ello.(AU)

Apomorfina y disfunción frontal en la enfermedad de Parkinson / Apomorphine and frontal dysfunction in Parkinson’s disease

Introducción: El trastorno disejecutivo y la apatía son síntomas característicos de la disfunción frontal ligada a la enfermedad de Parkinson. El efecto de la infusión continua subcutánea de apomorfina en la disfunción frontal no se conoce con detalle. Desarrollo: Se ha realizado una búsqueda y análisis de los trabajos publicados más relevantes en este campo. La apomorfina logra mejorías en las pruebas que miden tareas como la planificación, la atención, la fluencia verbal y la apatía. Conclusiones: Debido a su perfil farmacológico distintivo, con mayor actividad sobre los receptores dopaminérgicos de tipo D1, la apomorfina puede resultar beneficiosa en la disfunción frontal de la enfermedad.(AU)

Introduction: Dysexecutive disorder and apathy are characteristic symptoms of frontal dysfunction linked to Parkinson’s disease. The effect of continuous subcutaneous apomorphine infusion is not known in detail. Development: A search for the most relevant studies published to date in this field was carried out, along with their analysis. Apomorphine achieves improvements in tests that measure tasks such as planning, attention, verbal fluency and apathy. Conclusions: Due to its distinctive pharmacological profile, with enhanced activity on D1-type dopaminergic receptors, apomorphine may have beneficial effects on the frontal dysfunction produced by the diseas.(AU)

A guide to classify tattoo motives in Mexico as a tool to identify unknown bodies.

JUSTIFICATION: In Mexico, the number of unidentified bodies has been steadily rising for years. By now, more than 50,000 bodies are considered unidentified. Forensic laboratories that could perform comparative molecular genetic investigation are often overburdened and examinations can take months. Therefore, pragmatic approaches that can help to identify more unknown bodies must be sought. The increased use of distinctive physical features might be one, and the high rate of tattooed people in Mexico points towards a great potential of tattoos as a tool for identification. The prerequisite for a comparison of antemortem (missing persons) and postmortem (unknown bodies) data is an objective description of the particularities, e.g., of the tattoos. The aim of this study was to establish an objective classification for tattoo motives, taking into consideration local preferences. METHODS: In the database of the medicolegal services of the Instituto Jaliscience de Ciencias Forenses (IJCF) in Guadalajara, postmortem data of 1000 tattooed bodies from 2019 were evaluated. According to sex and age, the tattooed body localization and the tattoo motives were categorized. RESULTS: The 1000 tattooed deceased showed tattoos on 2342 body localizations. The motives were grouped and linked to the following 11 keywords (with decreasing frequency): letters/numbers, human, symbol (other), plant, symbol (religious), animal, object, fantasy/demon/comic, tribal/ornament/geometry, other, unrecognizable. CONCLUSION: Using the proposed classification, tattoo motives can be described objectively and classified in a practical way. If used for antemortem (missing persons) and postmortem (unknown bodies) documentation, motives can be searched and compared efficiently-helping to identify unknown bodies.
