RESUMO

Ocean currents are emerging as key contributors to renewable energy generation. However, technologies for harvesting tidal current energy are still in the early stages of development. In this context, environmental and economic studies on tidal energy converters (TECs) are crucial to further advance tidal technology and facilitate its entry into the market. This article presents a life cycle and economic assessment of a 34.5 MW tidal farm project comprising 23 second-generation tidal devices, each with a rated power of 1.5 MW. The tidal system was simulated using primary data from the full-scale floating platform Atir. The Atir is a pre-commercial tidal device designed with a steel trimaran and a submerged section for TEC installation. An assessment of 18 environmental impact categories was conducted using the ReCiPe 2016 MidPoint method, with process flow systems modelled using SimaPro v9.2.0.1 software. The environmental assessment indicates emissions of 42.11 g CO2eq per kWh, primarily stemming from manufacturing processes that demand substantial amounts of steel. The economic analysis reveals a Levelized Cost of Electricity (LCOE) of 0.125 EUR/kWh, consistent with European Commission projections. Although the platform structure represents a high initial investment, the lower maintenance costs of the Atir device provide long-term savings and, overall, result in a competitive LCOE. The study also introduces a methodological framework for harmonised environmental and economic assessments in tidal energy projects, proving crucial in supporting decision-making processes.

RESUMO

El síndrome de Parsonage-Turner o plexopatía braquial idiopática es una inflamación total o parcial del plexo braquial cuya presentación típica es una omalgia intensa y súbita, seguida de debilidad braquial y amiotrofia precoz. La etiología es desconocida, aunque se propone un mecanismo inmunomediado.El trasplante de progenitores hematopoyéticos es un tratamiento bien establecido de las neoplasias hematológicas y tiene un papel creciente en el tratamiento de enfermedades autoinmunes. Los efectos adversos neurológicos son probablemente infradiagnosticados.La asociación del síndrome de Parsonage-Turner y el trasplante de progenitores hematopoyéticos es muy poco conocida. Describimos dos casos clínicos de plexopatía braquial idiopática tras trasplante de células stem (progenitores) hematopoyéticas (TPH).La reconstitución del sistema inmune tras un trasplante de progenitores hematopoyéticos puede ser un desencadenante de plexopatía braquial, aunque se necesitan más estudios para entender la fisiopatología de esta entidad y establecer su relación causal con el trasplante.

RESUMO

INTRODUCTION AND OBJECTIVES: Pulmonary rehabilitation (PR) is a fundamental intervention to manage COPD, however, maintaining its benefits is challenging. Engaging in physical activity might help to prolong PR benefits. This study assessed the efficacy and effectiveness of a personalised community-based physical activity programme to sustain physical activity and other health-related PR benefits, in people with COPD. MATERIALS AND METHODS: This was a multicentre, assessor blinded, randomised controlled trial. Following 12-weeks of PR, people with COPD were assigned to a six-months personalised community-based physical activity programme (experimental group), or to standard care (control group). Physical activity was assessed via: time spent in moderate to vigorous physical activities per day (primary outcome measure), steps/day and the brief physical activity assessment tool. Secondary outcomes included sedentary behaviour, functional status, peripheral muscle strength, balance, symptoms, emotional state, health-related quality of life, exacerbations and healthcare utilization. Assessments were performed immediately post-PR and after three- and six-months. Efficacy and effectiveness were evaluated using intention-to-treat and per-protocol analysis with linear mixed models. RESULTS: Sixty-one participants (experimental group: n = 32; control group: n = 29), with balanced baseline characteristics between groups (69.6 ± 8.5 years old, 84 % male, FEV1 57.1 ± 16.7 %predicted) were included. Changes in all physical activity outcomes and in one-minute sit-to-stand were significantly different (P < 0.05) between groups at the six-month follow-up. In the remaining outcomes there were no differences between groups. CONCLUSIONS: The community-based physical activity programme resulted in better physical activity levels and sit-to-stand performance, six-months after completing PR, in COPD. No additional benefits were observed for other secondary outcomes.

RESUMO

This study investigated the effects of EPO on hemoglobin (Hgb) and hematocrit (Hct), time trial (TT) performance, substrate oxidation, and skeletal muscle phenotype throughout 28 days of strenuous exercise. Eight males completed this longitudinal controlled exercise and feeding study using EPO (50 IU/kg body mass) 3×/week for 28 days. Hgb, Hct, and TT performance were assessed PRE and on Days 7, 14, 21, and 27 of EPO. Rested/fasted muscle obtained PRE and POST EPO were analyzed for gene expression, protein signaling, fiber type, and capillarization. Substrate oxidation and glucose turnover were assessed during 90-min of treadmill load carriage (LC; 30% body mass; 55 ± 5% V̇O2peak) exercise using indirect calorimetry, and 6-6-[2H2]-glucose PRE and POST. Hgb and Hct increased, and TT performance improved on Days 21 and 27 compared to PRE (p < 0.05). Energy expenditure, fat oxidation, and metabolic clearance rate during LC increased (p < 0.05) from PRE to POST. Myofiber type, protein markers of mitochondrial biogenesis, and capillarization were unchanged PRE to POST. Transcriptional regulation of mitochondrial activity and fat metabolism increased from PRE to POST (p < 0.05). These data indicate EPO administration during 28 days of strenuous exercise can enhance aerobic performance through improved oxygen carrying capacity, whole-body and skeletal muscle fat metabolism.

RESUMO

Insulin insensitivity decreases exogenous glucose oxidation and metabolic clearance rate (MCR) during aerobic exercise in unacclimatized lowlanders at high altitude (HA). Whether use of an oral insulin sensitizer before acute HA exposure enhances exogenous glucose oxidation is unclear. This study investigated the impact of pioglitazone (PIO) on exogenous glucose oxidation and glucose turnover compared with placebo (PLA) during aerobic exercise at HA. With the use of a randomized crossover design, native lowlanders (n = 7 males, means ± SD, age: 23 ± 6 yr, body mass: 84 ± 11 kg) consumed 145 g (1.8 g/min) of glucose while performing 80 min of steady-state (1.43 ± 0.16 V̇o2 L/min) treadmill exercise at HA (460 mmHg; [Formula: see text] 96.6 mmHg) following short-term (5 days) use of PIO (15 mg oral dose per day) or PLA (microcrystalline cellulose pill). Substrate oxidation and glucose turnover were determined using indirect calorimetry and stable isotopes ([13C]glucose and 6,6-[2H2]glucose). Exogenous glucose oxidation was not different between PIO (0.31 ± 0.03 g/min) and PLA (0.32 ± 0.09 g/min). Total carbohydrate oxidation (PIO: 1.65 ± 0.22 g/min, PLA: 1.68 ± 0.32 g/min) or fat oxidation (PIO: 0.10 ± 0.0.08 g/min, PLA: 0.09 ± 0.07 g/min) was not different between treatments. There was no treatment effect on glucose rate of appearance (PIO: 2.46 ± 0.27, PLA: 2.43 ± 0.27 mg/kg/min), disappearance (PIO: 2.19 ± 0.17, PLA: 2.20 ± 0.22 mg/kg/min), or MCR (PIO: 1.63 ± 0.37, PLA: 1.73 ± 0.40 mL/kg/min). Results from this study indicate that PIO is not an effective intervention to enhance exogenous glucose oxidation or MCR during acute HA exposure. Lack of effect with PIO suggests that the etiology of glucose metabolism dysregulation during acute HA exposure may not result from insulin resistance in peripheral tissues.NEW & NOTEWORTHY Short-term (5 days) use of the oral insulin sensitizer pioglitazone does not alter circulating glucose or insulin responses to enhance exogenous glucose oxidation during steady-state aerobic exercise in young healthy men under simulated acute (8 h) high-altitude (460 mmHg) conditions. These results indicate that dysregulations in glucose metabolism in native lowlanders sojourning at high altitude may not be due to insulin resistance at peripheral tissue.

RESUMO

Introducción y objetivos: La presencia de hemorragia medular es considerada como un factor de mal pronóstico evolutivo en el estudio de la lesión medular traumática (LMT). No obstante, se ha sugerido en trabajos publicados que el pronóstico de los sangrados de menor tamaño no es tan negativo. El objetivo del presente trabajo es valorar la evolución neurológica en individuos con hemorragia intraparenquimatosa en función del tamaño de la misma. Material y métodos: Estudio observacional retrospectivo. Recopilados los pacientes ingresados por LMT aguda con estudio de resonancia, que objetivase una hemorragia medular entre los años 2010 y 2018. Se establecieron 2 grupos en función del tamaño del sangrado: microhemorragias (menor de 4mm) y macrohemorragias (superior a 4mm). Se comparó la exploración neurológica al ingreso y al alta atendiendo al grado AIS y el índice motor (IM). Resultados: Recogidos 46 casos, 17 microhemorragias y 29 macrohemorragias. El 70,6% de las primeras eran AIS A mientras que entre las macrohemorragias el porcentaje era del 89,6%. Al momento del alta se apreció una mejoría del grado AIS en el 40,0% de las microhemorragias por un 4,0% de las macrohemorragias (p=0,008). El IM inicial fue muy similar, 45,2±22,2 en las microhemorragias y 40,9±20,4 en las mayores (p=0,459), pero al alta era superior en el primer grupo: 60,4±20,5 por 42,7±22,8 (p=0,033). Ocho pacientes (17,4%) fallecieron durante el ingreso. Conclusiones: Existe relación entre el tamaño de la hemorragia intraparenquimatosa y el pronóstico neurológico de la LMT, presentando una mejor evolución las hemorragias menores de 4mm.(AU)


Introduction and objectives: The presence of spinal cord hemorrhage is considered as a poor prognostic factor in traumatic spinal cord injury (SCI). However, it has been suggested in published works that the prognosis of small hemorrhages is not so negative. The aim of this paper is to assess the neurological evolution in individuals with intraparenchymal hemorrhage according to its size. Material and methods: Retrospective observational study. Selected all the patients admitted for acute traumatic SCI between 2010 and 2018 with early magnetic resonance study and spinal cord hemorrhage. Two groups were established depending on the size of the bleeding: microhemorrhages (less than 4mm) and macrohemorrhages (greater than 4mm). The neurological examination at admission and discharge was compared according to the AIS grade and the motor score (MS). Results: Forty-six cases collected, 17 microhemorrhages and 29 macrohemorrhages. 70.6% of the microhemorrhages were AIS A while among macrohemorrhages the percentage was 89.6%. At the time of discharge, an improvement in the AIS grade was observed in 40.0% of the microhemorrhages compared to 4.0% of the macrohemorrhages (P=.008). Initial MS was similar, 45.2±22.2 in the microhemorrhages and 40.9±20.4 in the macrohemorrhages (P=.459), but at discharge it was higher in the first group: 60.4±20.5 for 42.7±22.8 (P=.033). Eight patients (17.4%) died during admission. Conclusions: There is a relationship between the size of the intraparenchymal hemorrhage and the neurological prognosis of SCI, with hemorrhages smaller than 4mm presenting a better evolution.(AU)

RESUMO

OBJECTIVE: To determine the efficacy of two physiotherapeutic interventions - aquatic therapy (AT) and land-based therapy (LBT) - for reducing pain in women with fibromyalgia. DESIGN: Single-blind, randomised controlled, equivalence trial. SETTING: Fibromyalgia, Chronic Fatigue Syndrome and Multiple Chemical Sensitivity Association in A Coruña, Spain. PARTICIPANTS: Forty women with fibromyalgia were assigned at random in a 1:1 manner to two groups: AT (n = 20) and LBT (n = 20). INTERVENTIONS: Two therapeutic exercise programmes, with 60-min sessions, were undertaken three times per week for 12 weeks. Sessions were carried out in groups by a trained physiotherapist. OUTCOME: The primary outcome was pain intensity (visual analogue scale). The secondary outcomes were pressure pain threshold (algometer), quality of life (Revised Fibromyalgia Impact Questionnaire), sleep quality (Pittsburgh Sleep Quality Index), fatigue (Multidimensional Fatigue Inventory) and physical ability (6-Minute Walk Test). Patients were evaluated at baseline, 12 weeks (post-treatment) and 18 weeks (follow-up). The statistical analysis was per-protocol. P < 0.05 was considered to indicate significance. Effect size was calculated. RESULTS: The mean age was 50 [standard deviation (SD) 9] years, with median body mass index of 27 [interquartile range (IQR) 25-30] kg/m2 and median symptom duration of 11 (IQR 6-15) years. No differences were observed between the groups post-treatment, but differences in favour of AT were found in pain intensity [2.7 (IQR 1.5-4.9) vs 5.5 (IQR 3.3-7.6); p= 0.023; large effect, Cohen's d= 0.8; 95% confidence interval (CI) 0.1-1.5] and sleep quality [12.0 (IQR 7.3-15.3) vs 15.0 (IQR 13.0-17.0); p= 0.030; large effect, Cohen's d= 0.8; 95% CI 0.1-1.5] at follow-up. CONCLUSIONS: The results suggest that AT is better than LBT for reducing pain intensity and improving sleep quality after 6 weeks of follow-up. AT may be a good treatment option for women with fibromyalgia. CLINICAL TRIALS REGISTRATION NUMBER: ClinicalTrials.gov NCT02695875 CONTRIBUTION OF THE PAPER.

RESUMO

Parsonage-Turner syndrome or idiopathic brachial neuritis is a total or partial inflammation of the brachial plexus, with a typical presentation as a sudden and very intense pain in the shoulder, followed by weakness and early amyotrophy. The etiology is still unknown, although an immune mediated mechanism is thought to be involved. Hematopoietic stem cell transplantation is a well-established treatment for hematological malignancies, but with a growing implication in the treatment of autoimmune diseases. The neurological side effects are probably underdiagnosed. The association of the Parsonage-Turner syndrome and the hematopoietic stem cell transplantation is scarce. We describe two clinical cases of idiopathic brachial plexopathy after hematopoietic stem cell transplantation. The reconstruction of the immune system after a transplant may be the trigger of a brachial plexopathy, but more studies are necessary for the etiology of this disease to be understood and to establish a cause-effect relation with the transplant.

RESUMO

Objetivo Analizar la repercusión del antidepresivo vortioxetina sobre la función sexual, frente a inhibidores selectivos de la recaptación de serotonina (ISRS) e inhibidores selectivos mixtos de la recaptación de serotonina y noradrenalina (IRSN o Duales) en pacientes con depresión. Material y métodos Estudio analítico, observacional, longitudinal y prospectivo en el que se incluyeron hombres y mujeres mayores de 18años con trastorno depresivo y actividad sexual en pareja, separándolos en dos grupos: 1)de estudio: inician tratamiento con vortioxetina; 2)control: mantienen tratamiento con ISRS o Duales. Se realizaron tres visitas: inclusión, seguimiento a las 4semanas y final 3meses desde la inclusión. El periodo total de seguimiento fue de 3meses. Resultados Se incluyeron 87 pacientes (edad media, 46,85años). Al final del estudio se hallaron diferencias significativas (DS) en el valor medio de la suma de las puntuaciones de los dominios evaluadores de la respuesta sexual del cuestionario de Función Sexual de la Mujer (FSM-2) entre el grupo de estudio y el de control (22,42±4,39 y 16,13±7,76, respectivamente), con menor riesgo de disfunción sexual en las mujeres tratadas con vortioxetina. También menor riesgo de disfunción sexual en estas mismas mujeres en los dominios de deseo, lubricación, orgasmo, frecuencia sexual y satisfacción sexual. Estas diferencias no se hallaron al evaluar la función sexual masculina. Conclusiones Las mujeres tratadas con vortioxetina presentaron mejor función sexual que las tratadas con ISRS o Duales y menor riesgo de disfunción sexual (AU)


Objective To analyze the impact of the antidepressant vortioxetine on sexual function, compared to selective serotonin reuptake inhibitors (SSRIs) and mixed selective serotonin and norepinephrine reuptake inhibitors (IRSN or Dual) in patients with depression. Material and methods Analytical, observational, longitudinal and prospective study, which included men and women over 18years of age, with depressive disorder and sexual activity with a partner, separating them into two groups: (i)study, starting treatment with vortioxetine; (2)control, maintaining treatment with SSRIs or Duals. Three visits were made: inclusion, follow-up at 4weeks and final 3months from inclusion. The total follow-up period was 3months. Results A total of 87 patients were included (mean age 46.85years). At the end of the study, significant differences (SD) were found in the mean value of the sum of the scores of the evaluative domains of the sexual response of the Women's Sexual Function Questionnaire (FSM-2) between the study group and the control (22.42±4.39 and 16.13±7.76, respectively), with a lower risk of sexual dysfunction in women treated with vortioxetine. Also, lower risk of sexual dysfunction in these same women in the domains of desire, lubrication, orgasm, sexual frequency and sexual satisfaction. These differences were not found when assessing male sexual function. Conclusions Women treated with vortioxetine presented better sexual function than those treated with SSRIs or Duals and a lower risk of sexual dysfunction (AU)

RESUMO

Two scales have been developed and validated in English to evaluate the impact of tremor on daily life, namely Quality of life in Essential Tremor Questionnaire (QUEST) and Essential Tremor Embarrassment Assessment (ETEA). The psychometric properties of the French version of these two scales were assessed for 117 patients with head tremor. Both scales showed excellent acceptability, very good internal consistency (Cronbach's alpha coefficient>0.8) and reproducibility (Lin concordance coefficient>0.8), satisfactory external validity and satisfactory sensitivity to change. In conclusion, the French versions of QUEST and ETEA are comprehensive, valid and reliable instruments for assessing patients with head tremor.

RESUMO

The rapid growth and intensification of aquaculture industries have led to an increased use of antibiotics. Consequently, growing concerns have mounted over the environmental contamination of these drugs from medicated feeds and the risk that this poses for antimicrobial resistance. To circumvent environmental leaching, farmers topcoat medicated feeds with oil; however, this only partially addresses the issue. This study investigated the potential of food-grade pregelatinized corn starch (PGS) as a second top-coating agent to reduce oxytetracycline (OTC) leaching from the hand-mixed medicated feed. We immersed top-coated medicated feeds for different periods of time and measured the concentration of OTC in the water to determine leaching. We found a significantly lower level of OTC in water samples collected from the PGS-coated medicated feed compared to the non-PGS-coated medicated feed, with concentrations of OTC approximately 4 and 2.6 times the latter after 5 min and 2 h of water immersion, respectively. We also fed PGS-coated antibiotic feed to jade perch to determine if fish accepted the top-coating and whether they absorbed the OTC. Results from a feeding trial suggested no difference in palatability between PGS and non-PGS-coated medicated feed. We also found that muscle tissue from fish fed with the aforementioned diets had similar levels of OTC concentrations, suggesting that PGS coating does not alter the gastrointestinal absorption of this medication. From our experiment, we conclude that PGS is potentially a new top-coating agent to reduce leaching in hand-mixed OTC medicated feed.

RESUMO

La profesión farmacéutica tiene un ámbito de intervención único en el área de la salud, donde el farmacéutico se pude encontrar en todos los dominios relacionados con el acceso a la atención sanitaria, en sus más variados niveles. Todo este alcance se basa en una formación académica amplia, donde el conocimiento científico y los saberes confieren habilidades que se reflejan de manera directa sobre la profesión y la práctica farmacéutica. La práctica profesional del farmacéutico es muy diversa y se puede observar en diversas circunstancias, desde el contacto directo con el paciente, con la persona, como en la farmacia comunitaria, farmacia hospitalaria, laboratorio de análisis clínicos, en residencias de ancianos, hasta en situaciones de mayor resguardo, como en el laboratorio o en la investigación científica y clínica. Esta amplia gama de actividad del farmacéutico, apoyada en relaciones laborales individuales o integrada en equipos de salud multidisciplinares, requiere de él un comportamiento asertivo y una conciencia (bio)ética que le permita responder a las diferentes demandas que enfrenta en su vida diaria. Es importante, pues, reflexionar sobre los conceptos y presupuestos que la ética o la bioética tienen en su vida profesional, en el área de la salud y las ciencias de la vida, y, por qué no, en la vida personal de cada uno.

The pharmaceutical profession has a unique scope of intervention in the area of health, where the pharmacist can be found in all domains related to access to health care, at its most varied levels. All this scope is based on a broad academic training, where scientific knowledge and expertise confer skills that are directly reflected on the pharmaceutical profession and practice. The professional practice of the pharmacist is very diverse and can be observed in various circumstances, from direct contact with the patient, with the person, as in community pharmacy, hospital pharmacy, clinical analysis laboratory, palliative or continuous care, in nursing homes, to in more reserved situations, such as in the laboratory or in scientific and clinical research. This wide range of activity of the pharmacist, supported by individual labor relations or integrated into multidisciplinary health teams, requires from him an assertive behavior and a (bio)ethical awareness that allows him to respond to the different demands he faces in his daily life. It is important, therefore, to reflect on the concepts and assumptions that ethics or bioethics have in the professional life of pharmacist, in the area of health and life sciences, and in the personal life of each one.

RESUMO

Objetivo Valorar en individuos con lesión medular traumática (LMT) la relación en re la mortalidad y la necesidad de UCI y las alteraciones objetivadas mediante resonancia magnética (RM) precoz, analizando alteraciones parenquimatosas, disrupción de ligamentos vertebrales (DLV) y compresión del cordón medular (CCM). Diseño Estudio retrospectivo. Ámbito Hospital de tercer nivel, unidad de lesionados medulares y UCI. Pacientes Individuos con LMT aguda entre los años 2010 y 2019. Intervenciones Análisis de RM realizada en las primeras 72horas. Variables de interés Ingreso en UCI y mortalidad. Resultados Recogidos 269 casos. El patrón que se asoció a una mayor mortalidad fue la hemorragia (16,7%) por 12,5% de los edemas a un nivel y 6,5% de los edemas a múltiples niveles (p=0,125). Lo mismo aconteció con los ingresos en UCI: 69,0% en hemorragia por 60,2% en edema múltiple y 46,3% en edemas cortos (p=0,018). Con respecto a la CCM, la mortalidad fue del 13,4% con 59,2% de ingresos en UCI por 2,2% y 42,2% de quienes no presentaban compresión (p=0,020 y p=0,003). Las cifras de éxitus e ingreso en UCI en los individuos con DLV fueron del 15,0% y el 67,3%, respectivamente, por un 6,2% y 44,4% de los individuos sin DLV (p<0,001 y p=0,013). Conclusiones La presencia de hemorragia medular, CCM y DLV se asoció a una mayor necesidad de UCI. Existe un significativo aumento de la mortalidad en los casos con CCM y DLV (AU)


Objective To assess in individuals with traumatic spinal cord injury (TSCI) the relationship between mortality and need for ICU and early magnetic resonance imaging (MRI), analyzing spinal parenchymal alterations, disruption of vertebral ligaments (DVL) and spinal cord compression (SCC). Design Retrospective study. Setting Third-level hospital, Spinal Cord Injury Unit and ICU. Patients Individuals with acute TSCI between 2010 and 2019. Interventio Analysis of MRI performed in the first 72h. Variables of interest Admission to ICU and mortality. Results 269 cases collected. The pattern that demonstrated higher mortality was cord hemorrhage (16.7%) for 12.5% of single-level edema and 6.5% of multilevel edema (p=0.125). The same happened with ICU admissions: 69.0% in hemorrhage, 60.2% in multilevel edema and 46.3% in short edema (p=0.018). Analyzing CCM, mortality was 13.4% with 59.2% of ICU admissions, for 2.2% and 42.2% of individuals without cord compression (p=0.020 and p=0.003). The figures of death and ICU admission among cord injuries with DVL were 15.0% and 67.3%, for 6.2% and 44.4% of the individuals without DLV (p<0.001 and p=0.013). Conclusions The presence of spinal cord hemorrhage, SCC and DVL was associated with a higher admission in ICU. A significant increase in mortality was observed in cases with SCC and DVL (AU)

RESUMO

Although the pour plate method is widely employed in microbiological quality control, it has certain drawbacks, including having to melt the culture medium before seeding. In this study, the preparation of the culture medium was modified by using a lower concentration of agar (10 g/L), which was separated from the nutrients during sterilization. The new protocol was assessed in media frequently used in microbiological quality control of food, cosmetics, and pharmaceutical products, with tryptic soy agar (TSA), Sabouraud 4% dextrose agar (SDA), and violet red bile glucose agar (VRBG). In comparison with the conventionally produced media, the modifications significantly improved the growth of Saccharomyces cerevisiae in SDA, Staphylococcus aureus, Salmonella enterica subsp. enterica serovar Typhimurium, and Candida albicans in TSA and Escherichia coli ATCC 8739 and ATCC 25922 and S. Typhimurium in VRBG. The modified VRBG was also more selective for Pseudomonas aeruginosa. Regarding physicochemical properties, a significantly lower pH was observed in TSA and VRBG and lower strength values in TSA. Sterilizing agar separately from the other components of the medium and reducing the agar concentration to 10 g/L can improve microorganism growth and enhance the selectivity of differential media in the pour plate method. These modifications could facilitate the automation of this culture technique. IMPORTANCE In the era of rapid microbiological methods, there is a need to improve long-established culture techniques. Drawbacks of the pour plate method include having to melt each medium separately before seeding. For this technique, we demonstrate that separating the agar from the other components of commonly used media during sterilization and reducing the agar concentration to 10 g/L can enhance microbial growth. The new protocol could have advantages in routine laboratory practice because less agar is required and the same molten agar suspension can be used to prepare different media. Moreover, these modifications could facilitate the automation of the pour plate method.

RESUMO

Sleep restriction alters gut microbiota composition and intestinal barrier function in rodents, but whether similar effects occur in humans is unclear. This study aimed to determine the effects of severe, short-term sleep restriction on gut microbiota composition and intestinal permeability in healthy adults. Fecal microbiota composition, measured by 16S rRNA sequencing, and intestinal permeability were measured in 19 healthy men (mean ± SD; BMI 24.4 ± 2.3 kg/m2, 20 ± 2 years) undergoing three consecutive nights of adequate sleep (AS; 7-9 h sleep/night) and restricted sleep (SR; 2 h sleep/night) in random order with controlled diet and physical activity. α-diversity measured by amplicon sequencing variant (ASV) richness was 21% lower during SR compared to AS (P = 0.03), but α-diversity measured by Shannon and Simpson indexes did not differ between conditions. Relative abundance of a single ASV within the family Ruminococcaceae was the only differentially abundant taxon (q = 0.20). No between-condition differences in intestinal permeability or ß-diversity were observed. Findings indicated that severe, short-term sleep restriction reduced richness of the gut microbiota but otherwise minimally impacted community composition and did not affect intestinal permeability in healthy young men.
