Effect of food shortage and temperature on age 0+ salmonids: a contribution to predict the effects of climate change.

Brown trout Salmo trutta alevins were maintained at 8 and 11° C at three conditions over a 9 day period from yolk sac exhaustion: fed ad libitum, starved or fed ad libitum after starvation. Whole-body gene expressions for proteins involved in energy metabolism and the two primary proteolytic pathways were assessed. This study is the first to show an over-expression of proteasome and autophagy-related genes in young stages of salmonids, particularly at 11° C.

Obesity-dependent metabolic signatures associated with nonalcoholic fatty liver disease progression.

Our understanding of the mechanisms by which nonalcoholic fatty liver disease (NAFLD) progresses from simple steatosis to steatohepatitis (NASH) is still very limited. Despite the growing number of studies linking the disease with altered serum metabolite levels, an obstacle to the development of metabolome-based NAFLD predictors has been the lack of large cohort data from biopsy-proven patients matched for key metabolic features such as obesity. We studied 467 biopsied individuals with normal liver histology (n=90) or diagnosed with NAFLD (steatosis, n=246; NASH, n=131), randomly divided into estimation (80% of all patients) and validation (20% of all patients) groups. Qualitative determinations of 540 serum metabolite variables were performed using ultraperformance liquid chromatography coupled to mass spectrometry (UPLC-MS). The metabolic profile was dependent on patient body-mass index (BMI), suggesting that the NAFLD pathogenesis mechanism may be quite different depending on an individual's level of obesity. A BMI-stratified multivariate model based on the NAFLD serum metabolic profile was used to separate patients with and without NASH. The area under the receiver operating characteristic curve was 0.87 in the estimation and 0.85 in the validation group. The cutoff (0.54) corresponding to maximum average diagnostic accuracy (0.82) predicted NASH with a sensitivity of 0.71 and a specificity of 0.92 (negative/positive predictive values=0.82/0.84). The present data, indicating that a BMI-dependent serum metabolic profile may be able to reliably distinguish NASH from steatosis patients, have significant implications for the development of NASH biomarkers and potential novel targets for therapeutic intervention.

The effects of aerobic exercise and transcranial direct current stimulation on cognitive function in older adults with and without cognitive impairment: A systematic review and meta-analysis.

BACKGROUND: Aerobic exercise (AE) may slow age-related cognitive decline. However, such cognition-sparing effects are not uniform across cognitive domains and studies. Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation and is also emerging as a potential alternative to pharmaceutical therapies. Like AE, the effectiveness of tDCS is also inconsistent for reducing cognitive impairment in ageing. The unexplored possibility exists that pairing AE and tDCS could produce synergistic effects and reciprocally augment cognition-improving effects in older individuals with and without cognitive impairments. Previous research found such synergistic effects on cognition when cognitive training is paired with tDCS in older individuals with and without mild cognitive impairment (MCI) or dementia. AIM: The purpose of this systematic review with meta-analysis was to explore if pairing AE with tDCS could augment singular effects of AE and tDCS on global cognition (GC), working memory (WM) and executive function (EF) in older individuals with or without MCI and dementia. METHODS: Using a PRISMA-based systematic review, we compiled studies that examined the effects of AE alone, tDCS alone, and AE and tDCS combined on cognitive function in older individuals with and without mild cognitive impairment (MCI) or dementia. Using a PICOS approach, we systematically searched PubMed, Scopus and Web of Science searches up to December 2021, we focused on 'MoCA', 'MMSE', 'Mini-Cog' (measures) and 'cognition', 'cognitive function', 'cognitive', 'cognitive performance', 'executive function', 'executive process', 'attention', 'memory', 'memory performance' (outcome terms). We included only randomized controlled trials (RTC) in humans if available in English full text over the past 20 years, with participants' age over 60. We assessed the methodological quality of the included studies (RTC) by the Physiotherapy Evidence Database (PEDro) scale. RESULTS: Overall, 68 studies were included in the meta-analyses. AE (ES = 0.56 [95% CI: 0.28-0.83], p = 0.01) and tDCS (ES = 0.69 [95% CI: 0.12-1.26], p = 0.02) improved GC in all three groups of older adults combined (healthy, MCI, demented). In healthy population, AE improved GC (ES = 0.46 [95% CI: 0.22-0.69], p = 0.01) and EF (ES = 0.27 [95% CI: 0.05-0.49], p = 0.02). AE improved GC in older adults with MCI (ES = 0.76 [95% CI: 0.21-1.32], p = 0.01). tDCS improved GC (ES = 0.69 [90% CI: 0.12-1.26], p = 0.02), all three cognitive function (GC, WM and EF) combined in older adults with dementia (ES = 1.12 [95% CI: 0.04-2.19], p = 0.04) and improved cognitive function in older adults overall (ES = 0.69 [95% CI: 0.20-1,18], p = 0.01). CONCLUSION: Our systematic review with meta-analysis provided evidence that beyond the cardiovascular and fitness benefits of AE, pairing AE with tDCS may have the potential to slow symptom progression of cognitive decline in MCI and dementia. Future studies will examine the hypothesis of this present review that a potentiating effect would incrementally improve cognition with increasing severity of cognitive impairment.

[Reasons residents choose to specialize in anesthesiology and postoperative critical care in the autonomous community of Madrid]. / Motivación de los residentes de Anestesia-Reanimación de la Comunidad de Madrid en la elección de su especialidad.

OBJECTIVES: Our main objective was to determine the reasons why residents chose to specialize in anesthesiology and postoperative critical care in the autonomous community of Madrid. We also wished to know if prior contact with this specialty influenced their choice, if those who chose it as a second specialization differed from those who were doing a first residency, what expectations the residents had and if they had been met, and if they were satisfied with their training. MATERIAL AND METHODS: Survey of all residents in anesthesiology and postoperative critical care medicine in the community of Madrid between November 2008 and February 2010. The questionnaire items covered demographic data, prior specialty training, undergraduate contact with the specialty, reasons for choosing this specialty (technical, social, or employment-related interests), satisfaction, and expectations met. RESULTS: We received 89 valid questionnaires, a sample that represented 35% of the residents. The reasons expressed most often were learning and performing techniques (97.8%); that the specialty was dynamic, with broad theoretical and practical content (98.9%), and an interest in providing critical care (93.3%). These 3 reasons were considered important or very important by most of the respondents; 55.8% considered that learning and carrying out techniques was the most important reason. All the respondents who had previously done specialty training said they were dissatisfied. Prior contact with the specialty was associated with having different reasons and interests, such as an interest in pain (F = .037) or emulating a role model (P = .014). CONCLUSIONS: The specialty's mix of theoretical and practical content and the chance to perform techniques and provide critical care are the features the residents find most attractive. Residents who already have another specialty are less satisfied and their expectations are not as well met.

The causal role of the left parietal lobe in facilitation and inhibition of return.

Following non-informative peripheral cues, responses are facilitated at the cued compared to the uncued location at short cue-target intervals. This effect reverses at longer intervals, giving rise to Inhibition of Return (IOR). The integration-segregation hypothesis (Lupiáñez, 2010) suggests that peripheral cues always produce an onset-detection cost regardless the behavioral cueing effect that is measured - either facilitation or IOR. In the present study, we used transcranial magnetic stimulation (TMS) to investigate the causal contribution of this detection cost to performance. We used a cueing paradigm with a target discrimination task that was preceded by a non-informative peripheral cue. The presence-absence of a central intervening event was manipulated. Online TMS to the left superior parietal lobe (compared to an active vertex stimulation) lead to an overall more positive effect (faster responses for cued as compared to uncued trials), by putatively impairing the detection cost contribution to performance. The data revealed a strong association between overall RT and the TMS effect, and also between overall RT and the integrity of the first branch of the left superior longitudinal fascicule. These results have critical implications not only for the open debate about the mechanism/s underlying spatial orienting effects, but also for the growing literature demonstrating that white matter connectivity is crucial for explaining inter-individual behavioral variability.

[Analysis of resident anesthesiologists' difficulties with epidural analgesia for labor and childbirth and complication rates]. / Análisis de las dificultades y complicaciones de la analgesia epidural para el trabajo de parto realizada por médicos residentes.

OBJECTIVES: To analyze the number of attempts to provide an epidural or spinal-epidural block for labor and complication rates when the procedures are performed by resident or staff anesthesiologists. MATERIAL AND METHODS: Prospective, observational study in all women who asked for epidural or spinal-epidural analgesia for labor and childbirth over a 2-month period. RESULTS: We enrolled 1097 women. The procedure was performed by residents in 74.6% of the cases. The mean (SD) number of attempts needed to perform the technique was 1.46 (0.9) regardless of whether the anesthesiologist was a resident or on staff. Accidental dural puncture occurred in 14 cases (1.3%). The most common complication during puncture was paresthesia (34.1%), and the difference between the rates for staff anesthesiologists and residents was not significant. Asymmetric analgesia was the most common complication during the dilatation phase (37.4%). CONCLUSIONS: The number of attempts needed was 1.28 for staff anesthesiologists and 1.52 for residents (P = .02). The differences between the 2 groups in the incidences of complications (blood noted during puncture, accidental dural puncture, pain during expulsion, repeat epidural or spinal puncture, nausea, or back pain) were not significant.

Modern approach to an old technique: Narrative revision of techniques used to locate the epidural space. / Visión moderna sobre una técnica antigua: revisión narrativa de técnicas de localización del espacio epidural.

Since the first description of the epidural technique during the 1920s, the continuous progress of knowledge of the anatomy and physiology of the epidural space has allowed the development of different techniques to locate this space while increasing both the safety and efficacy of the procedure. The most common techniques used today are based on the two main characteristics of the epidural space: the difference in distensibility between the ligamentum flavum and the epidural space, and the existence of negative pressure within the epidural space. However, over recent years, technological advances have allowed the development of new techniques to locate the epidural space based on other physical properties of tissues. Some are still in the experimental phase, but others, like ultrasound-location have reached a clinical phase and are being used increasingly in daily practice.

Recommendations on the use of deep neuromuscular blockade by anaesthesiologists and surgeons. AQUILES (Anestesia QUIrúrgica para Lograr Eficiencia y Seguridad) Consensus. / Recomendaciones sobre el uso de bloqueo neuromuscular profundo por parte de anestesiólogos y cirujanos. Consenso AQUILES (Anestesia QUIrúrgica para Lograr Eficiencia y Seguridad).

INTRODUCTION: Neuromuscular blockade enables airway management, ventilation and surgical procedures. However there is no national consensus on its routine clinical use. The objective was to establish the degree of agreement among anaesthesiologists and general surgeons on the clinical use of neuromuscular blockade in order to make recommendations to improve its use during surgical procedures. METHODS: Multidisciplinary consensus study in Spain. Anaesthesiologists experts in neuromuscular blockade management (n=65) and general surgeons (n=36) were included. Delphi methodology was selected. A survey with 17 final questions developed by a dedicated scientific committee was designed. The experts answered the successive questions in two waves. The survey included questions on: type of surgery, type of patient, benefits/harm during and after surgery, impact of objective neuromuscular monitoring and use of reversal drugs, viability of a multidisciplinary and efficient approach to the whole surgical procedure, focussing on the level of neuromuscular blockade. RESULTS: Five recommendations were agreed: 1) deep neuromuscular blockade is very appropriate for abdominal surgery (degree of agreement 94.1%), 2) and in obese patients (76.2%); 3) deep neuromuscular blockade maintenance until end of surgery might be beneficial in terms of clinical aspects, such as as immobility or better surgical access (86.1 to 72.3%); 4) quantitative monitoring and reversal drugs availability is recommended (89.1%); finally 5) anaesthesiologists/surgeons joint protocols are recommended. CONCLUSIONS: Collaboration among anaesthesiologists and surgeons has enabled some general recommendations to be established on deep neuromuscular blockade use during abdominal surgery.

Self-focusing arrest of femtosecond laser pulses in air at different pressures.

We study analytically and numerically the self-focusing arrest of femtosecond laser pulses in air at different pressures in the presence of an external focus lens. Analytical estimations as well as results of simulations show that the intensity at which the self-focusing arrest occurs is almost independent of the gas pressure. However, a dependence on the temperature is found. The Raman effect is taken into account, and an estimation of the intensity inside of filaments at high altitudes is given.

[Perioperative treatment of a pregnant woman with recent cerebral infarction secondary to noncompaction cardiomyopathy]. / Tratamiento perioperatorio de una gestante con infarto cerebral reciente secundario a miocardiopatía no compactada.

Recent-onset noncompaction of the myocardium is a rare but serious entity with uncertain prognosis. Cerebral infarction is among the forms of presentation, and pregnancy and hypercoagulability increase risk. We report the case of a pregnant woman brought to the emergency department with ischemic cerebral infarction. Investigation demonstrated the cause to be cardiac embolism, and noncompaction of the myocardium was diagnosed. She was stabilized and a few days later underwent elective cesarean section under general anesthesia. Surgery and postoperative recovery were uneventful, and she was transferred for rehabilitation. Myocardial injury and progression to cerebrovascular accident must be prevented in such cases; the patient must be stabilized and antiplatelet and/or anticoagulant therapy initiated before surgery. Hemodynamic stability must be maintained throughout the perioperative period and neonatal depression avoided after delivery. Various approaches are available to be adapted to the patient's situation.

Fidel Pagés Miravé en el centenario de su publicación de 1921. Historia de la anestesia epidural / Fidel Pagés Miravé one hundred years after its publication in 1921. The history of epidural anaesthesia

Sicard y Cathelin en 1901, introducen de manera simultánea la administración sacra de fármacos. En 1919, Läwen fue un gran defensor de la anestesia regional. Gil-Vernet en 1917 describe los fundamentos anatómicos de la técnica de abordaje sacro al espacio epidural. Fidel Pagés Miravé es el verdadero introductor de la anestesia epidural. Su artículo publicado en 1921, Anestesia Metamérica, en la Revista Española de Cirugía, constituye un hito en la historia de la anestesia. Diez años más tarde Dogliotti publica sus resultados, sin citar la aportación de Pagés. La gran mayoría de los historiadores citan a Dogliotti en la bibliografía, ignorando a Pagés. Gutiérrez un cirujano argentino alertó del error histórico y revindicó la aportación original de Pagés. En la actualidad todos los libros de historia de la anestesia reseñan la publicación de Pagés. El anestesiólogo cubano Manuel Martínez Curbelo, introduce en la clínica la anestesia epidural continua. En esta publicación revisamos la historia del abordaje sacro, torácico y lumbar del espacio epidural. Describimos las distintas agujas y catéteres utilizados. En la práctica diaria anestésica la analgesia/anestesia epidural se utiliza en cirugía, analgesia del trabajo del parto, tratamiento del dolor agudo y crónico. (AU)

Sicard and Cathelin in 1901 introduced independently the sacral injection of drugs. In 1910 Läwen was an enthusiastic defender of regional anaesthesia. Gil-Vernet in 1917 introduced new anatomical concepts in epidural sacral approach. Fidel Pagés Mirave was true pioneer of epidural anaesthesia. His publication in 1921, Metameric Anaesthesia, in the Spanish Journal of Surgery is a landmark in the history of world anaesthesia. Ten years later Dogliotti published his experiences with epidural anaesthesia, without anyreference to Pagés’ research. Most medical historians date the regular use of epidural anaesthesia from Dogliotti’s paper, published ten years later, and ignoring Pagés research. Gutierrez a surgeon born in Argentina, recognized the error and promoted the original scientific publication of Pages. Today all the important books of anaesthesia reference the first discoverer of epidural anaesthesia. The Cuban anaesthesiologist Manuel Martinez Curbelo, introduced into clinical practice continuous epidural anaesthesia. In this article we review the history of sacral and thoracic and lumbar approach to the epidural space, its different needles and catheters used in these techniques. Epidural analgesia/ anaesthesia are commonly used in daily practice in surgery, labour pain, and in the treatment of acute and chronic pain. (AU)

"Do not do" recommendations of the Spanish Society of Anaesthesiology, Critical Care and Pain Therapy. "Commitment to Quality by Scientific Societies" Project. / Recomendaciones de «no hacer¼ de la Sociedad Española de Anestesiología, Reanimación y Terapéutica del Dolor. Proyecto «Compromiso por la Calidad de las Sociedades Científicas¼.

In April 2013 the Ministry of Health (MSSSI) adopted the project called "Commitment to Quality by Scientific Societies in Spain", in response to social and professional demands for sustainability of the health system. The initiative is part of the activities of the Spanish Network of Agencies for Health Technology Assessment and Services of the National Health System, and is coordinated jointly by the Quality and Cohesion Department, the Aragon Institute of Health Sciences (IACS), and the Spanish Society of Internal Medicine (SEMI). All the scientific societies in Spain have been included in this project, and its main objective is to reduce the unnecessary use of health interventions in order to agree "do not do" recommendations, based on scientific evidence. The primary objective was to identify interventions that have not proven effective, have limited or doubtful effectiveness, are not cost-effective, or do not have priority. Secondary objectives were: reducing variability in clinical practice, to spread information between doctors and patients to guide decision-making, the appropriate use of health resources and, the promotion of clinical safety and reducing iatrogenesis. The selection process of the 5 "do not do" recommendations was made by Delphi methodology. A total of 25 panellists (all anaesthesiologists) chose between 15 proposals based on: evidence that supports quality, relevance, or clinical impact, and the people they affect. The 5 recommendations proposed were: Do not maintain deep levels of sedation in critically ill patients without a specific indication; Do not perform preoperative chest radiography in patients under 40 years-old with ASA physical status I or II; Do not systematically perform preoperative tests in cataract surgery unless otherwise indicated based on clinical history and physical examination; Do not perform elective surgery in patients with anaemia at risk of bleeding until a diagnostic workup is performed and treatment is given; and not perform laboratory tests (blood count, biochemistry and coagulation) prior to surgery in healthy or low risk patients (ASA I and II) with minimal estimated blood loss.

Variational analysis of self-focusing of intense ultrashort pulses in gases.

By using perturbation theory we derive an expression for the electrical field of a Gaussian laser beam propagating in a gas medium. This expression is used as a trial solution in a variational method to get quasi-analytical solutions for the width, intensity, and self-focusing distance. The approximation gives a better agreement with results of numerical simulations for a broad range of values of the input power than previous analytical results available in the literature. The results apply in the case of ultrashort pulses too.

AIDS risk-taking behavior during carnival in São Paulo, Brazil.

OBJECTIVE: The Brazilian Carnival is thought to be a time when the risk of HIV infection is likely to be high. We therefore compared the risk during Carnival to risk in the past month among male samba school participants in São Paulo, Brazil. SUBJECTS AND METHODS: A cross-sectional study was conducted among 380 male samba school drummers randomly sampled during rehearsal for the 1993 Carnival in São Paulo by means of a 20-min interviewer-administered questionnaire. The main outcome variable was condom use with non-steady partners. RESULTS: The sexual behavior of 36.1% of subjects risked HIV infection, but only 9.7% of all subjects were at risk only during Carnival. Subjects with a sexual risk of HIV differed from those without risk in substance use, attitudes towards condoms and expectations about Carnival; those who were at risk only during Carnival did not differ from those who were at risk at other times. About half of the subjects had been given free condoms during Carnival, although few of the men at risk had actually used them. CONCLUSIONS: Though more than a third of the drummers were at risk of HIV infection, only a small per cent were at risk only during Carnival. The level of sexual risk of HIV infection is probably better explained by factors in the men's daily lives, rather than through information on risks taken during Carnival. These results raise questions concerning the efficacy of universal condom distribution during Carnival, since about half of the men were given condoms but few of those at risk actually used them. A targeted distribution of condoms to populations with a high demonstrated risk may be more effective in preventing new HIV infection.

Socioeconomic status and risk of HIV-1, syphilis and hepatitis B infection among sex workers in São Paulo State, Brazil. Instituto Adolfo Lutz Study Group.

OBJECTIVES: To determine how HIV risk behavior and the prevalences of sexually transmitted diseases vary according to socioeconomic status and city among sex workers in São Paulo State, Brazil. SUBJECTS AND METHODS: A cross-sectional study of 600 female sex workers (100 of a higher socioeconomic status and 100 of a lower socioeconomic status in each city) was conducted in the cities of São Paulo, Campinas and Santos. HIV risk behavior was assessed by questionnaire; serological tests were administered to assess prior exposure to HIV-1, syphilis and hepatitis B. RESULTS: Only statistically significant (P < 0.05) findings are reported here. Compared to those with a higher socioeconomic status, sex workers with a lower socioeconomic status worked longer hours each day (9.6 versus 7.9), had more clients per day (5.4 versus 2.6) and had fewer episodes of intercourse per client per encounter (1.1 versus 1.4). Levels of condom use for vaginal, anal and oral sex were significantly higher in Santos than in São Paulo or Campinas. Twenty-three per cent of the women said they feared violence if they insisted that their clients wear condoms; 74% voiced similar fears regarding their non-client sexual partners. Overall, 11% of sex workers were positive for exposure to HIV-1, 45% for syphilis and 39% for hepatitis B. Those with a lower socioeconomic status were more likely than those with a higher socioeconomic status to be infected with HIV-1 (17 versus 4%), syphilis (66 versus 24%) and hepatitis B (52 versus 26%), but there were no differences in prevalence rates by city. CONCLUSIONS: These data demonstrate substantial heterogeneity in HIV risk behavior and the prevalence of HIV-1 and other sexually transmitted diseases among sex workers in São Paulo State, many of which were related to differences in socioeconomic status. Interventions to prevent HIV transmission among sex workers must be tailored to the local environment and, in particular, to the socioeconomic status of these workers.

Influence of peak expiratory flow monitoring on an asthma self-management education programme.

We assessed whether peak expiratory flow monitoring added to a self-management education programme reduced morbidity and improved pulmonary function and adherence to treatment in 100 asthma patients (aged 17-65 years) with adequate treatment and regular 1-year follow-up. Patients randomized to the experimental group used peak expiratory flow readings as the basis for their therapeutic plan coupled with educational intervention, whereas patients in the control group received the same educational intervention and used symptoms only to guide self-management. Morbidity parameters, functional status and adherence to medical regimens improved in both groups, although the percentage of patients with satisfactory adherence was significantly better in the group with peak expiratory flow monitoring (83%) than in controls (52%) (P = 0.05). The multivariate analysis showed that severity of asthma (odds ratio 9.28, 95% confidence interval 1.87-45.96, P = 0.006 for moderate asthma) and type of self-management education programme (odds ratio: 6.19; 95% confidence interval: 2.04-18.81; P = 0.001 for the use of peak expiratory flow readings) were the only independent predictors of adherence to treatment. However, a statistically significant association between adherence and use of peak expiratory flow monitoring was only found in patients with moderate asthma (P = 0.0009). We conclude that peak expiratory flow monitorization in optimal conditions (adequate medical regimen, individualized self-management education and regular follow-up) showed a beneficial effect on adherence to prescribed regimens only in patients with moderate asthma.

First Report of Banana Streak Virus Infecting Sugarcane and Arrowroot in Colombia.

We have recently reported on the presence of banana streak virus (BSV) affecting plantains (Musa spp.) in Colombia (2). BSV is serologically related to sugarcane bacilliform virus and has been found to be transmitted by the pink mealybug (Saccharicoccus sacchari) from sugarcane to banana (1). In the vicinity of affected plantain crops in the localities of Andes (Antioquia) and Montenegro (Quindio), we observed sugarcane (Saccharum officinarum L.) plants with chlorotic streaks on their leaves, as well as arrowroot (Canna edulis Ker-Gawl.) plants with mild mosaic symptoms. The foliar tissue of symptomatic plants of these two species was tested for BSV and cucumber mosaic virus (CMV) by double antibody sandwich-enzyme-linked immunosorbent assay with commercial polyclonal antisera (Agdia Inc., Elkhart, IN). BSV was detected in samples of both plant species, whereas CMV was not detected in either one. Immunosorbent electron microscopy analysis of BSV-infected, symptomatic, foliar tissue of sugarcane showed the presence of viral-like bacilliform particles measuring approximately 150 × 30 nm, typical of BSV. This is the first report of BSV infecting Saccharum officinarum in Colombia and the first report of Canna edulis as a host for this virus. References: (1) B. E. L. Lockhart and L. J. C. Autrey.
