Introduction
The Food and Drug Administration (FDA) recently issued new warnings about the possible effects of the repeated or prolonged use of general anaesthesia and sedatives on the brain development of children under 4 years old during surgeries or paediatric procedures.
ObjectivesTo evaluate the possible long-term neurotoxic impact the exposure to general anaesthesia has on the paediatric population from 0 to 4 years, which is the period during which the brain develops.
MethodsInitially, a search for observational studies that described the risk of neurotoxicity and alterations in the long-term cognitive development of children exposed to general anaesthesia before 4 years of age, was performed in PubMed between 2016 and 2020.
ResultsFinally, 5 retrospective cohort studies comparing children exposed and not exposed to general anaesthesia were included in this study. None of these showed significant differences in their main study variables. However, three of this studies found significant differences in some of the secondary variables such as speed of processing, motor skills, internalization of behaviour and learning, and attention deficit hyperactivity disorder (ADHD).
ConclusionsIn vitro and in vivo studies of anesthetics have shown serious neurotoxic effects in the developing brain. However, the clinical relevance of these findings for children undergoing anesthesia remains unclear.
Most of these studies suggest a strong relationship between exposure to anesthesia in children aged 0 to 4 years, this being greater after multiple exposures. Despite these results, many of these articles conclude that further research is needed on this topic.

Why did some Bolivian departments have more success containing COVID-19 than others? We argue that low government legitimacy hampers coordinated responses to national crises, particularly where political polarization is severe and the crisis response becomes politicized. Low legitimacy can intensify the challenges of poverty and poor infrastructure. An original dataset of daily observations on subnational coronavirus policy and cell phone mobility data, paired with administrative data on cases and deaths, suggests that political divisions influenced governors’ policy implementation and citizens’ compliance. In departments that opposed the president, policies were more likely to deviate from the stricter national policy while mobility and protest activity were high. In departments aligned with the president, local policy followed national policy and citizens complied with policy and quarantine restrictions for a longer period of time.

Objective
Mitral valve anatomy has a significant impact on potential surgical options for patients with hypoplastic or borderline left ventricle. Papillary muscle morphology is a major component regarding this aspect. The purpose of this study was to use cardiac magnetic resonance to describe the differences in papillary muscle anatomy between normal, borderline, and hypoplastic left ventricles.
MethodsWe carried out a retrospective, observational cardiac magnetic resonance study of children (median age 5.36 years) with normal (n=30), borderline (n=22), or hypoplastic (n=13) left ventricles. Borderline and hypoplastic cases had undergone an initial hybrid procedure. Morphological features of the papillary muscles, location, and arrangement were analysed and compared across groups.
ResultsAll normal ventricles had two papillary muscles with narrow pedicles; however, 18% of borderline and 46% of hypoplastic cases had a single papillary muscle, usually the inferomedial type. In addition, in borderline or hypoplastic ventricles, the supporting pedicle occasionally displayed a wide insertion along the ventricular wall. The length ratio of the superolateral support was significantly different between groups (normal: 0.46±0.08; borderline: 0.39±0.07; hypoplastic: 0.36±0.1; p=0.009). No significant difference, however, was found when analysing the inferomedial type (0.42±0.09; 0.38±0.07; 0.39±0.22, p=0.39). The angle subtended between supports was also similar among groups (113°±17°; 111°±51° and 114°±57°; p=0.99). A total of eight children with borderline left ventricle underwent biventricular repair. There were no significant differentiating features for papillary muscle morphology in this subgroup.
ConclusionsThe superolateral support can be shorter or absent in borderline or hypoplastic left ventricle cases. The papillary muscle pedicles in these patients often show a broad insertion. These changes have important implications on surgical options and should be described routinely.

Cystic echinococcosis (CE) remains an important health problem in many areas of the world, including the Mediterranean region. We performed a retrospective study of cases reported from 1998 to 2012 in order to review and update the epidemiology of this disease in a highly endemic area situated in western Spain. A total of 471 patients were diagnosed with hydatid disease. Of these cases, 55·8% were male, with an average age of 62·3 ± 19·5 years. More importantly, 1·5% of patients were children, and 20·5% were aged <45 years. An active therapeutic approach was implemented for 92·6% of the CE patients with primary diagnoses; however, a ‘watch and wait’ strategy was used in 59·3% of all secondary CE diagnoses. The incidence rate of hydatid disease was significantly higher compared to the incidence described in the Notifiable Disease System in this area. Furthermore, a significant decrease in hydatid incidence during the years included in the study was observed (β = −0·4357, P < 0·001). CE incidence has diminished in recent years, although active transmission remains in paediatric cases. Additionally, CE incidence remains high in our region despite public health plans for its control. The documented incidence of CE disease clearly underestimates the real numbers.

Synthesis, structural, magnetic properties and heating efficiency of γ-Fe2O3 nanoparticles have been investigated. X-ray diffraction (XRD) and Mössbauer spectroscopy show that the obtained nanoparticles are mainly composed of maghemite phase (γ-Fe2O3). Williamson-Hall method shows that the crystallite is around 14nm.The specific absorption rate (SAR) under an alternating magnetic field is investigated as a function of frequency. A highest SAR value of 12W/g for frequency 523 kHz was obtained.

Although mortality is low after the modified Fontan procedure, there is a significant percentage of patients with prolonged postoperative recovery. The objective of this study is to evaluate the usefulness of postoperative administration of oral sildenafil and inhaled nitric oxide on early postoperative outcome.
A prospective interventional and comparison study with a historical cohort was conducted. Between January, 2010 and March, 2013, 16 patients received oral sildenafil during immediate modified Fontan postoperative period. Inhaled nitric oxide was also administered if the patient was kept intubated 12 hours after surgery. Early postoperative outcome was compared with a historical cohort of 32 patients on whom the modified Fontan procedure was performed between March, 2000 and December, 2009.
Postoperative administration of sildenafil and nitric oxide had no influence on early postoperative outcome after the modified Fontan procedure in terms of duration of pleural effusions, mechanical ventilation time, length of stay in the ICU, and length of hospital stay.

We introduce the concept of a rare element in a non-associative normed algebra and show that the existence of such an element is the only obstruction to continuity of a surjective homomorphism from a non-associative Banach algebra to a unital normed algebra with simple completion. Unital associative algebras do not admit any rare elements, and hence automatic continuity holds.

After the sinking of the oil carrier ‘Prestige’, which occurred in November 2002, approximately 60,000 mt of heavy oil (type M-100) were spilled into the ocean. Immediately after the accident, a series of management measures were applied to fisheries in the area, resulting in the establishment of various closed areas. Four of the most important fleets operating in the north and north-east of the Iberian Peninsula were affected (otter trawl, pair trawl, purse seine and hand line fishing gears). These fleets exploit important fisheries resources, some of them currently beyond their biological security limits. Reductions in effort were observed in all of them, particularly in the first three months of the ban and in the north-eastern area. However, apart from the hand line fleet, this did not involve a considerable reduction in the total effort produced by each of the fleets in 2003. The pair trawlers perform two trip types, but no differences in the specific composition were observed in any of them during the three years under analysis. Five types of trawling trip were identified, but important reductions were only observed for Norwegian lobster, with the fleet targeting this species as well as hake, megrim and monkfish.

Eighty-seven Manchego sucking lambs raised exclusively on maternal milk were slaughtered. The carcasses were weighed immediately after dressing and classified according to hot carcass weight (HCW): low HCW (<5.5 kg), medium HCW (5.5 to 6.5 kg) and high HCW (≥ 6.5 kg). The effects of this classification system on carcass and meat quality were studied. Carcass conformation improved as carcass weight increased; carcasses became more compact. Carcass fatness increased (P < 0.001) as carcasses became heavier. With regard to the joints, leg (P < 0.001) and shoulder (P < 0.05) proportions decreased as carcass weight increased, whereas loin-rib (P < 0.001) and flank (P < 0.001) proportions increased. The proportion of fat in the leg clearly increased in the heavier carcasses (P < 0.001), while that of bone decreased (P < 0.001) and that of muscle was not affected. pH at 24 h in the m. longissimus dorsi and m. semitendinosus decreased as carcass weight increased. The only meat colour parameter affected by carcass weight was the yellowness index; lighter-weight carcasses displayed lower index (P < 0.05). Cooking losses were unaffected as carcass weight increased, whereas with regard to tenderness, the shear force value tended to be higher in the low carcass weight group. No differences between carcass weight groups were found in the sensory analysis. Fatty acid composition did not show any significant effect due to carcass weight except in stearic fatty acid (C18:0); C18:0 proportion decreased (P < 0.01) as carcasses became heavier. Carcass weight affected carcass quality (all carcass quality parameters studied were higher in the heavier carcasses), whereas meat quality varied little as a result the small variation between carcass weights in sucking lambs.

Forty-eight sucking lambs (26 males and 22 females) of the Manchega breed were used in this work. Lambs were slaughtered at 10, 12 and 14 kg live weight. Carcass degree of fatness was assessed by three assessors from colour photographs of the carcasses, using the European Union scale for light lambs (EU), the Colomer-Rocher method (CF) and another new scale developed by our group (sucking lambs scale, SL). Carcass conformation was assessed according to the Colomer-Rocher method (CC). Fatness and conformation scales were divided to give 0·25 points in each interval. Left half-carcasses were jointed and dissected into lean, fat and bone. Muscle proportion, bone proportion and whole fat proportion (obtained by addition of every fat depot: subcutaneous fat, intermuscular fat, inguinal fat and kidney knob and channel fat) were determined. Male and female carcasses showed a very different tissue composition: both groups had statistically significant differences (P < 0·05) in 20 out of 25 tissue composition variates. Males showed a higher number of variates that were well correlated with assessors’ scoring than females. Correlation coefficients between most of the tissue composition variates and assessors’ scores were higher in males. Furthermore, the number of variates that were significantly correlated with assessors’ scores was lower in females. Therefore, subjective methods for the estimation of carcass degree of fatness and of carcass conformation are poor predictors of tissue composition in female sucking lamb carcasses.

Let A be a Banach algebra, and let D: A → A* be a continuous derivation, where A* is the topological dual space of A. The paper discusses the situation when the second transpose D**: A** → (A**)* is also a derivation in the case where A** has the first Arens product.

Three weaning treatments (weaning at 45 days of age, at 65 days of age, unweaned) and two slaughter weights (24 and 28 kg) were compared in lambs raised at pasture, and their effect on carcass and meat traits were studied. Unweaned lambs displayed a greater growth rate, lower concentrate consumption, greater dorsal fat thickness, more kidney knob and channel fat and greater total fat levels, measured through dissection of the hind limb. Total collagen concentration was lower in unweaned lambs and the intramuscular fat of these same animals exhibited a greater proportion of saturated fatty acids and a lower n-6/n-3 fatty acid ratio. Slaughter weight influenced scored carcass fatness, which was greater in heavier lambs, meat colour, which displayed greater lightness in lower-weight lambs, and water-holding capacity, which was lower in lambs with the lower slaughter weight. The heavier lambs displayed lower soluble collagen values, and the intramuscular fat of the longissimus dorsi muscle of these same lambs contained higher levels of monounsaturated and lower levels of polyunsaturated fatty acids.

Forty-five Talaverana breed sucking lambs of both sexes were slaughtered at 10 and 12 kg live weight in order to study the effect of gender and slaughter weight on carcass, meat and fat traits. Carcass dressing proportions and fatness (by various measures) were higher in females and heavier lambs, which also showed better conformation. Lightness (L*) of the carcass fat was higher in males and heavier lambs. Females and heavier lambs also displayed a greater proportion of fat on dissection, primarily due to a higher percentage of subcutaneous fat tissue. Water-holding capacity was greater in males and in lower-weight lambs. Males presented higher total collagen and lower soluble collagen values than females. In general, a high percentage of short-chain (C12:0 and C14:0) fatty acids, as well as of palmitic acid (C16:0), was observed in the intramuscular fat of the longissimus dorsi muscle, corresponding with an exclusively milk diet.
