Abstract
Cellular composition and the responsiveness of the immune system evolve upon aging and are influenced by biological sex. CD4+ T cells from women living with HIV exhibit a decreased viral replication ex vivo compared to men's. We, thus, hypothesized that these findings could be recapitulated in vitro and infected primary CD4+ T cells with HIV-based vectors pseudotyped with VSV-G or HIV envelopes. We used cells isolated from twenty donors to interrogate the effect of sex and age on permissiveness over a six-day activation kinetics. Our data identified an increased permissiveness to HIV between 24 and 72 h post-stimulation. Sex- and age-based analyses at these time points showed an increased susceptibility to HIV of the cells isolated from males and from donors over 50 years of age, respectively. A parallel assessment of surface markers' expression revealed higher frequencies of activation marker CD69 and of immune checkpoint inhibitors (PD-1 and CTLA-4) in the cells from highly permissive donors. Furthermore, positive correlations were identified between the expression kinetics of CD69, PD-1 and CTLA-4 and HIV expression kinetics. The cell population heterogeneity was assessed using a single-cell RNA-Seq analysis and no cell subtype enrichment was identified according to sex. Finally, transcriptomic analyses further highlighted the role of activation in those differences with enriched activation and cell cycle gene sets in male and older female cells. Altogether, this study brought further evidence about the individual features affecting HIV replication at the cellular level and should be considered in latency reactivation studies for an HIV cure.

Abstract
Oxidative stress and inflammation are mediators in the pathophysiology of several non-communicable diseases (NCDs). Tree nuts and peanuts lower risk factors of cardiometabolic disease, including blood lipids, blood pressure and insulin resistance, among others. Given their strong antioxidant/anti-inflammatory potential, it is plausible that nuts may also exert a favorable effect on inflammation and oxidative stress. Evidence from systematic reviews and meta-analyses of cohort studies and randomized controlled trials (RCTs) suggest a modest protective effect of total nuts; however, the evidence is inconsistent for specific nut types. In this narrative review, the state of evidence to date is summarized for the effect of nut intake on biomarkers of inflammation and oxidative stress, and an attempt is made to define the gaps in research while providing a framework for future research. Overall, it appears that some nuts, such as almonds and walnuts, may favorably modify inflammation, and others, such as Brazil nuts, may favorably influence oxidative stress. There is a pressing need for large RCTs with an adequate sample size that consider different nut types, and the dose and duration of nut intervention, while evaluating a robust set of biomarkers for inflammation and oxidative stress. Building a stronger evidence base is important, especially since oxidative stress and inflammation are mediators of many NCDs and can benefit both personalized and public health nutrition.

Abstract
We aimed to demonstrate the feasibility of 90-day cardiac monitoring with an external Holter device and to find a target population able to benefit from such a technique. Cryptogenic stroke patients were continuously monitored for 90 days with a textile wearable Holter (TWH). Compliance and quality of the monitoring were assessed by the number of hours of ECG stored per month. Mean predictors of pAF, including age, gender, stroke severity, and atrial size (LAVI), were evaluated. One-year follow-up assessed pAF detection outside per protocol monitoring. Out of 224 patients included in 5 stroke centers, 163 patients (72.76%) fulfilled the criteria for the protocol. Median monitoring time was similar among the three months. Per protocol pAF detection reached 35.37% at 90 days. The age (OR 1.095; 95% CI 1.03-1.14) and the LAVI (OR 1.055; 95% CI 1.01-1.09) independently predicted pAF. The cut-off point of 70 years (AUC 0.68) (95% CI 0.60-0.76) predicted pAF with a sensitivity of 75.8% and specificity of 50.5%. The LAVI cut-off point of 28.5 (AUC 0.67) (95% CI 0.56-0.77) had a sensitivity of 63.6% and a specificity of 61.8% to detect pAF. The combination of both markers enhanced the validity of pAF detection sensitivity to 89.6%, with a specificity of 27.59%. These patients had increased risk of pAF during the 90-day monitoring HR 3.23 (χ2 7.15) and beyond 90 days (χ2 5.37). Intensive 90-days TWH monitoring detected a high percentage of pAF. However, a significant number of patients did not complete the monitoring. Patients older than 70 years and with enlarged left atria benefitted more from the protocol.

Abstract
Nowadays, considering society's highly demanding lifestyles, it is important to consider the usefulness of relaxation from the perspective of both psychology and clinical practice. The response towards relaxation (RResp) is a mind-body interaction that relaxes the organism or compensates for the physiological effects caused by stress. This work aims to automatically detect the different mental states (relaxation, rest and stress) in which RResps may occur so that complete feedback about the quality of the relaxation can be given to the subject itself, the psychologist or the doctor. To this end, an experiment was conducted to induce both states of stress and relaxation in a sample of 20 university students (average age of 25.76 ± 3.7 years old). The electrocardiographic and electrodermal activity signals collected from the participants produced a dataset with 1641 episodes or instances in which the previously mentioned mental states take place. This data was used to extract up to 50 features and train several supervised learning algorithms (rule-based, trees, probabilistic, ensemble classifiers, etc.) using and not using feature selection techniques. Besides, the authors synthesised the cardiac activity information into a single new feature and discretised it down to three levels. The experimentation revealed which features were most discriminating, reaching a classification average accuracy of up to 94.01 ± 1.73 % with the 6 most relevant features for the own-collected dataset. Finally, being restrictive, the same solution/subspace was tested with a dataset referenced in the bibliography (WESAD) and scored an average accuracy of 90.36 ± 1.62 %.

Abstract
Power-quality events and operation transients in power systems (PS) with isolated neutral can saturate inductive voltage transformers (IVT), which, when interacting with the overhead and underground cable capacitances, can cause ferroresonance events in the local PS. This abnormal operating mode can partially or totally damage the transformers and switchgears within the affected PS. Distribution system operators (DSO) can minimize these effects by detecting ferroresonance events accurately and fast enough and changing the mode of operation accordingly. Direct detection methods, i.e., based on voltage measurements, are reliable, but the massive deployment of this solution is relatively expensive; i.e., power quality analyzers cost thousands of USD. Alternatively, indirect detection methods are also available, e.g., IVT vibration measurements with accelerometers costing hundreds of USD, but their reliability depends on the installation method used. This manuscript proposes using the acoustic noise caused by magnetostriction forces within the IVT core during ferroresonance events to detect their occurrence. Compared to other indirect methods, electret condenser microphones with preamplifying stage cost less than USD 10 and are less sensitive to the installation procedure. The proposed method is validated experimentally, and its performance compared to IVT vibration measurements one by using the same detection methodology.

Abstract
Psychiatric neurosurgery has resurfaced over the past two decades for the treatment of severe mental health disorders, with improved precision and safety over older interventions alongside the development of novel ones. Little is known, however, about current public opinions, expectations, hopes, and concerns over this evolution in neurotechnology, particularly given the controversial history of psychosurgery. To fill this knowledge gap, we conducted a study with eight focus groups in Vancouver and Montreal (Canada; n = 14), Berlin (Germany; n = 22), and Madrid (Spain; n = 12). Focus group texts were transcribed and analyzed using qualitative content analysis in the language local to each city, guided by the theoretical framework of pragmatic neuroethics. Findings indicate that participants across all cities hold concerns about the last resort nature of psychiatric neurosurgery and the potential impact on the authentic self of patients who undergo these procedures. The views captured serve to advance discussion on the appropriate timing for psychiatric neurosurgery, promote sound health policy for the allocation of this resource, and foster scientific literacy about advances for mental health internationally.

Abstract
Introducción Uno de los principales retos en el manejo de la COVID-19 es el aumento súbito de la demanda de camas de cuidados intensivos. En este artículo se describen las estrategias de gestión hospitalaria durante la escalada y desescalada de la respuesta a la epidemia de COVID-19 en un hospital terciario de Madrid. Materiales y métodos Los datos derivan del sistema informático del hospital y del plan de contingencia del mismo. Resultados La epidemia de COVID-19 produjo un rápido aumento de los pacientes con necesidad de cuidados intensivos, lo que saturó las camas de UVI disponibles en pocos días. El hospital tuvo que aumentar su capacidad abriendo cuatro UVI adicionales para proporcionar los cuidados necesarios a todos los pacientes. Los retos principales fueron relativos a la infraestructura hospitalaria, los materiales y el personal. Gracias a las estrategias de gestión utilizadas, el hospital fue capaz de aumentar su capacidad de camas de UVI en un 340%, proporcionar cuidados a todos los pacientes con necesidad y mantener una mínima actividad quirúrgica programada. Conclusiones La capacidad de un hospital de aumentar su capacidad para enfrentarse a eventos excepcionales es difícil de cuantificar y se enfrenta a limitaciones físicas (materiales, personal, espacios). Con una gestión flexible y adaptable durante eventos excepcionales se pueden alargar significativamente estos límites.

Abstract
Personality dimensions related with drug use are novelty seeking, impulsivity and harm avoidance. Studies predicting drug of choice over personality variables are controversial.ObjectiveTo describe personality profile of drug users in relation to substance of choice.AimsTo know personality dimension differences according to drug used.MethodsCloninger's TCI-R was administered to 218 patients in a dual diagnosis unit.SPSS was applied.ResultsOf the patients, 33.94% had personality disorder. Principal substances used were alcohol, cocaine and cannabis.Most of drug users had normal scores in each dimension. No high scores were found in reward dependence, self-directedness and cooperativeness with any drug.High scores were observed for novelty seeking in 42.9% of timulants users; for arm avoidance in a quarter of cocaine, alcohol and methadone users and for persistence in 18.2% of hypnotics users.Low scores were observed for reward dependence in 45% of heroine and hypnotics users; for persistence in 50% of methadone and 32% of cocaine users; for self-directedness in most of types of drug users and for cooperativeness in up to 50% in heroine, hypnotics, stimulants and cocaine users.Statistical significant differences were observed for cocaine use and high novelty seeking and low cooperation; for non cannabis use and high harm avoidance; for non anfetamine use and low scores in reward dependence; for opiate use and low self-directedness.ConclusionsMost of patients had normal scores in the different dimensions.Presence of comorbid personality disorder led us to consider the results with caution.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND The INBUILD trial investigated the efficacy and safety of nintedanib versus placebo in patients with progressive fibrosing interstitial lung diseases (ILDs) other than idiopathic pulmonary fibrosis (IPF). We aimed to establish the effects of nintedanib in subgroups based on ILD diagnosis. METHODS The INBUILD trial was a randomised, double-blind, placebo-controlled, parallel group trial done at 153 sites in 15 countries. Participants had an investigator-diagnosed fibrosing ILD other than IPF, with chest imaging features of fibrosis of more than 10% extent on high resolution CT (HRCT), forced vital capacity (FVC) of 45% or more predicted, and diffusing capacity of the lung for carbon monoxide (DLco) of at least 30% and less than 80% predicted. Participants fulfilled protocol-defined criteria for ILD progression in the 24 months before screening, despite management considered appropriate in clinical practice for the individual ILD. Participants were randomly assigned 1:1 by means of a pseudo-random number generator to receive nintedanib 150 mg twice daily or placebo for at least 52 weeks. Participants, investigators, and other personnel involved in the trial and analysis were masked to treatment assignment until after database lock. In this subgroup analysis, we assessed the rate of decline in FVC (mL/year) over 52 weeks in patients who received at least one dose of nintedanib or placebo in five prespecified subgroups based on the ILD diagnoses documented by the investigators: hypersensitivity pneumonitis, autoimmune ILDs, idiopathic non-specific interstitial pneumonia, unclassifiable idiopathic interstitial pneumonia, and other ILDs. The trial has been completed and is registered with ClinicalTrials.gov, number NCT02999178. FINDINGS Participants were recruited between Feb 23, 2017, and April 27, 2018. Of 663 participants who received at least one dose of nintedanib or placebo, 173 (26%) had chronic hypersensitivity pneumonitis, 170 (26%) an autoimmune ILD, 125 (19%) idiopathic non-specific interstitial pneumonia, 114 (17%) unclassifiable idiopathic interstitial pneumonia, and 81 (12%) other ILDs. The effect of nintedanib versus placebo on reducing the rate of FVC decline (mL/year) was consistent across the five subgroups by ILD diagnosis in the overall population (hypersensitivity pneumonitis 73·1 [95% CI -8·6 to 154·8]; autoimmune ILDs 104·0 [21·1 to 186·9]; idiopathic non-specific interstitial pneumonia 141·6 [46·0 to 237·2]; unclassifiable idiopathic interstitial pneumonia 68·3 [-31·4 to 168·1]; and other ILDs 197·1 [77·6 to 316·7]; p=0·41 for treatment by subgroup by time interaction). Adverse events reported in the subgroups were consistent with those reported in the overall population. INTERPRETATION The INBUILD trial was not designed or powered to provide evidence for a benefit of nintedanib in specific diagnostic subgroups. However, its results suggest that nintedanib reduces the rate of ILD progression, as measured by FVC decline, in patients who have a chronic fibrosing ILD and progressive phenotype, irrespective of the underlying ILD diagnosis.

Abstract
BACKGROUND Burn scars are common in the paediatric population. When involving the face, it diminishes quality of life. Ablative fractional laser (AFL) therapy is becoming the preferred choice for established scars due to its greater potential depth for thermal injury (4 mm), which leads to photothermolysis with subsequent neocollagenesis and collagen fibre realignment and remodelling. Combined with small z-plasties and topical steroids, it has been proven to: flatten and decrease the volume of scars, increase pliability and decrease pruritus and erythema. The purpose of the case series was to determine the clinical significance of a single session of AFL therapy, combined with small z-plasties and topical steroids on facial scars post burn injury. METHOD Four cases of paediatric facial scarring post burns were selected to undergo a single treatment of AFL therapy, accompanied by small z-plasties and topical steroids. Modified Vancouver Scar Scores (MVSS) pre- and postoperatively at 3 and 6 months were evaluated. RESULTS Improvement of all components of the MVSS was achieved after 6 months, with major improvement in scar pliability and symptomatology. The mean MVSS improved from 14 (range 12-16) preoperatively to 5 and 5.5 respectively at 3 and 6 months postoperatively. Non-parametric analysis with Friedman Two-Way ANOVA by Rank showed a statistical significance between the pre- and postoperative MVSS (p = 0.024). CONCLUSION AFL should form an integral part of the burn scar armamentarium.

Abstract
Abstract
Background
Proprotein convertase subtilisin–kexin type 9 (PCSK9) inhibitors have demonstrated to induce large reductions in low-density lipoprotein cholesterol (LDLc) and major cardiovascular events but none of the studies was statistically powered to demonstrate reductions in specific endpoints rather than a combined end-point of major cardiovascular events.
Methods
We performed an intention-to-treat meta-analysis in line with recommendations from the Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement using currently available studies involving PCSK9 inhibitors. The endpoint assessed were acute coronary syndrome (ACS) and stroke.
Results
We included 81,544 patients, 41,147 treated with a PSCK9 inhibitors: 17,179 with evolocumab; 13,718 with bococizumab and 10,250 with alirocumab (table 1). A total of 1,316 ACS were registered in the treatment group vs. 1,608 in controls, resulting in 18.0% reduction associated with PCSK9 treatment (figure 1). This result was reproduced exactly in the EBCT althougt a non-significant heterogeneity was detected (p=0.052). Metaregression analyses did not demonstrate the implication of the study (p=0.45), study drugs (p=0.26), age (p=0.89), hypertension (p=0.81) or diabetes (p=0.81) on such result.
Results on stroke incidence are presented in figure 2. PCSK9 inhibitors treatment resulted in a 24% reduction of stroke when all studies were analyzed together; heterogeneity was statistically significant (p=0.021) but it was not observed in the EBCT analysis where PCSK9 inhibitors were associated with 24% stroke incidence reduction.
Conclusions
The meta-analysis of currently available studies demonstrates that PCSK9 inhibitors treatment reduces the incidence of ACS by 18% and stroke by 24%.

Abstract
Power transformers are the most important assets of electric power substations. The reliability in the operation of electric power transmission and distribution is due to the correct operation and maintenance of power transformers. The parameters that are most used to assess the health status of power transformers are dissolved gas analysis (DGA), oil quality analysis (OQA) and content of furfuraldehydes (FFA) in oil. The parameter that currently allows for simple online monitoring in an energized transformer is the DGA. Although most of the DGA continues to be done in the laboratory, the trend is online DGA monitoring, since it allows for detection or diagnosis of the faults throughout the life of the power transformers. This study presents a review of the main DGA monitors, single- or multi-gas, their most important specifications, accuracy, repeatability and measurement range, the types of installation, valve or closed loop, and number of analogue inputs and outputs. This review shows the differences between the main existing DGA monitors and aims to help in the selection of the most suitable DGA monitoring approach according to the needs of each case.

Abstract
Water ice exists on many objects in space. The most abundant icy species, among them water, are present in the icy satellites of the outer Solar System giant planets. The nuclei of comets, which are mainly composed of water ice, give another example of its abundance. In the interstellar medium (ISM), ice mantles, formed by molecular species sticking on dust grains, consist mainly of water ice. All these objects are exposed to ionizing radiation like ions, UV photons, and electrons. Sputtering of atoms, molecules, ions, and radicals from icy surfaces may populate and maintain exospheres of icy objects in the Solar System. In other respects, ionized hydrides such as OH+, H2O+, and H3O+ have been detected in the gas phase in star-forming regions. Interactions with cosmic rays could be an additional explanation to the current models for the formation of those species. In fact, laboratory simulations showed that the main components of the sputtered ionic species from water ice are oxygen hydrides. In this work, water ice targets were irradiated at several temperatures (10-200 K) by 90 keV O6+ ions, yielding an electronic stopping power of about 12 eV/Å, when the nuclear stopping power is comparable to the electronic stopping power. Sputtering of secondary ions after bombardment of the ice target was analyzed by time-of-flight mass spectrometry (TOF-SIMS). Besides hydrogen ions (H+, H2+, H3+), also O+, O2+, OH+, (H2O)+, and clusters of (H2O)nH+ with n = 1-8 are emitted. Our results show a progressive yield decrease with increasing temperature of all of the detected species. This is related to the structure of the ice: the ionic sputtering yield for crystalline ice is much lower than for an amorphous ice. For instance, amorphous ice at 10 K exhibits a yield of the order of 2 × 10-6 secondary (H2O)nH+ hydride ions/projectile (with n = 1-8). As the temperature is increasing toward the phase transition to crystalline ice, the yields decrease by about one order of magnitude.

Abstract
A brain-computer interface (BCI), based on motor imagery EEG, uses information extracted from the electroencephalography signals generated by a person who intends to perform any action. One of the most important issues of current research is how to detect automatically whether the user intends to send some message to a certain device. This study presents a proposal, based on a hierarchical structured system, for recognising intentional and non-intentional mental tasks on a BCI system by applying machine learning techniques to the EEG signals. First-level clustering is performed to distinguish between intentional control (IC) and non-intentional control (NC) state patterns. Then, the patterns recognised as IC are passed on to a second stage where supervised learning techniques are used to classify them. In BCI applications, it is critical to correctly classify NC states with a low false positive rate (FPR) to avoid undesirable effects. According to the literature, we selected a maximum FPR of 10%. Under these conditions, our proposal achieved an average test accuracy of 66.6%, with an 8.2% FPR, for the BCI competition IIIa dataset. The main contribution of this paper is the hierarchical approach, based on machine learning paradigms, which performs intentional and non-intentional discrimination and, depending on the case, classifies the intended command selected by the user.

Abstract
Thermal injuries amongst infants are common and a cause of significant mortality and morbidity in South Africa. This has been attributed to the lack of an enabling environment (poverty-related lack of safe living conditions) and the cognitive and physical developmental immaturity of infants, who depend on their surroundings and adults to keep them safe. This is a retrospective observational study of 548 infant admissions over 48 months. Infant was defined as children below 13 months of age. The 548 infants constituted 23% of all paediatric burn admissions of ages 0-12 years. Three hundred and fourteen were males (57%) and 234 (42.7%) females. The infants were divided in a pre-ambulatory group of 143 (26%) infants of 0-6 months and an ambulatory group of 7 months to 12 months consisting of 457 (83.3%). The total body surface area (TBSA) ranged from 2-65%. Seventy-six percent (417 infants) occurred in the home environment. Scalds accounted for 86% (471 infants) and 6% (33 infants) were as a result of flame burns. Non-accidental injuries accounted for 1.2%. The anatomical distributions varied between the pre-ambulatory and ambulatory groups. Conservative management was done in 397 (72.4%) and 101(18.4%) infants underwent surgery. Infection was suspected in 76 (13.5%) infants with positive blood cultures in 15(20%) of the 76. ICU care was received in 46 (8.3%) infants and 15 (32.6%) of these had inhalation injuries. Of the inhalation injuries 11(23.9%) infants underwent mechanical ventilation of an average of 4.4 days. Ventilator associated pneumonia was diagnosed in 8(17%) of the ventilated children. The mortality rate was 0.36%. The surgically treated patients acquired more complications than the conservatively treated group. Special treatment considerations should be considered in this paediatric sub-group.

Abstract
PURPOSE To compare adhesion scores, repair strength and histological findings among sublay, onlay and primary repair incisional hernioplasty techniques. Surgical repairs were employed directly on healthy animals, without previous hernia induction, to avoid confounding factors related to hernia development. METHODS Forty Wistar rats were divided into four groups, control, simulation, onlay and sublay. After 42 days, adhesion intensity, tensile strength of the abdominal wall and anatomopathological histological substrate were compared. RESULTS SL group presented greater adhesion scores (p < 0.0001), higher tensiometric (p < 0.0001), and was characterized by more histiocytes, mononuclear cells, macrovacuolar granulomas and type I collagen on histological analysis. Pearson correlation between adhesions and tensiometry, and between tensiometry and neocollagenization showed a strong positive association (r = 0.8905 and 0.6757, respectively in SL group, p < 0.05). CONCLUSION Mesh positioning in sublay compartment was followed by increased adhesion development and provides a stronger mesh-tissue attachment, in addition, resulted in a different histological profile of the inflammation/repair substrate. The intensity of these findings was directly correlated, suggesting they could be the result of a common biological phenomenon. Our findings indicate that mesh placement following the retromuscular technique generates a superior repair response, and give clues to a better understanding of the superiority of sublay repair in achieving lower recurrence rates. Characterization of the cellular and molecular elements responsible for the superiority of this technique is in our view an essential prerequisite aiming for improvements in the therapeutic options for the treatment of this disease.

Abstract
Marine litter presents a global problem, with increasing quantities documented in recent decades. The distribution and abundance of marine litter on the seafloor off the United Kingdom's (UK) coasts were quantified during 39 independent scientific surveys conducted between 1992 and 2017. Widespread distribution of litter items, especially plastics, were found on the seabed of the North Sea, English Channel, Celtic Sea and Irish Sea. High variation in abundance of litter items, ranging from 0 to 1835 pieces km-2 of seafloor, was observed. Plastic tems such as bags, bottles and fishing related debris were commonly observed across all areas. Over the entire 25-year period (1992-2017), 63% of the 2461 trawls contained at least one plastic litter item. There was no significant temporal trend in the percentage of trawls containing any or total plastic litter items across the long-term datasets. Statistically significant trends, however, were observed in specific plastic litter categories only. These trends were all positive except for a negative trend in plastic bags in the Greater North Sea - suggesting that behavioural and legislative changes could reduce the problem of marine litter within decades.

Abstract
Oxytocin has been administered to patients with autism spectrum disorder (ASD) in order to improve social skills, communication, and manage repetitive behaviors in the context of research trials. The majority of the studies focus on acute administration; thus, the effectiveness and potential side effects of chronic administration remain unknown. The main goal of this case report is to highlight the importance of the safety parameters for the chronic use of intranasal oxytocin administration. In a single case conducted in our outpatient clinic, one adolescent (15 years old) received intranasal oxytocin (24 IU) twice per day, in accordance with the recommended doses for this age group that varies from 8 - 25 IU twice per day. After three weeks of treatment, the patient presented with gynecomastia. While it is not certain that the gynecomastia was oxytocin-induced, this case highlights the importance of developing optimal regimens for chronic oxytocin administration, with a particular focus on safety parameters.

Abstract
BACKGROUND Telemedicine is increasingly applied in developed settings to facilitate transfer of information to and from burn surgeons across vast geographic areas. WhatsApp is a widely available and extremely user-friendly encrypted smartphone application that does not require the expensive physical and personnel infrastructure that characterizes many of these telemedicine systems. The aim of this study was to review the use of WhatsApp to facilitate paediatric burn injury consultations to a regional burn centre in a developing country, where burn care continues to be thwarted by administrative apathy, poor resource allocation and lack of attention to medical and nursing education at all levels. METHODS A retrospective review was undertaken of all consultations using WhatsApp over an 18-month period, received by the burn centre's two senior medical practitioners. The specific origin and nature of the telemedicine requests for advice, transfer or follow-up were collected, as were data relating to the demographics of the patients, the aetiology, mechanism and extent of the burn injury. The impact of the system of communication in terms of reductions in admissions and clinic visits was assessed, and a cost analysis was undertaken. Feedback was also obtained from those health practitioners regularly using the service. RESULTS 838 communications occurred during the study period, which included 1562 distinct clinical queries. 486 interactions (58%) originated from within the hospital, the majority of which were initiated by surgeons in training or burn nurse practitioners. 352 (42%) consultations were from outside the hospital. Queries related to the full spectrum of burn care, including emergency management and stabilization, triage and transfer, the need for escharotomy, fluid resuscitation, wound care, the timing and nature of surgical intervention, as well as follow-up and rehabilitation. While no significant changes in the number of surgical interventions or admissions were observed when compared to the five years prior to the intervention, outpatient visits reduced significantly during the study period. It was estimated that over 150 unnecessary admissions were also avoided as a result of the triage made possible by WhatsApp, which translated into considerable cost saving for the institution. DISCUSSION Incorporating WhatsApp technology into the daily processes of burn care has significantly improved the quality of paediatric burn care referrals to specialist burn services. Specifically, WhatsApp has contributed to reductions in unnecessary referrals and outpatient visits, facilitated opportunities for continuing medical education, improved the care of major burn injuries through more effective prehospital communication, and enabled greater allocation of scarce specialist resources at the burn centre. This study motivates for the wider application of WhatsApp for burn care referrals, especially in developing countries.

Abstract
We propose a new SU(3)C ⊗ SU(2)L ⊗ U(1)Y ⊗ U(1)X gauge model which is non universal respect to the three fermion families of the Standard Model. We introduce additional one top-like quark, two bottom-like quarks and three right handed neutrinos in order to have an anomaly free theory. We also consider additional three right handed neutrinos which are singlets respect to the gauge symmetry of the model to implement see saw mechanism and give masses to the light neutrinos according to the neutrino oscillation phenomenology. In the context of this horizontal gauge symmetry we find mass ansatz for leptons and quarks. In particular, from the analysis of solar, atmospheric, reactor and accelerator neutrino oscillation experiments, we get the allow region for the Yukawa couplings for the charge and neutral lepton sectors according with the mass squared differences and mixing angles for the two neutrino hierarchy schemes, normal and inverted.

Abstract
This article presents a case of unsuccessful pharmaceutical and invasive pain treatment for 6 years without any adequate diagnostics in a female suffering from unilateral thoracic radiculopathy (Th8, right) leading to severe disability and unemployment. The origin was an undetected Tarlov cyst. After resection of the cyst the pain and other complaints disappeared (follow up: 8 months) without need for further pain medication. This case underlines the necessity of adequate diagnostics ahead of long-term pain treatment. Thoracic Tarlov cysts are very uncommon but should be included in the differential diagnosis because curative treatment may be possible.

Abstract
Persistence of minimal residual disease (MRD) after treatment for myeloma predicts inferior outcomes, but within MRD-positive patients there is great heterogeneity with both early and very late relapses. Among different MRD techniques, flow cytometry provides additional information about antigen expression on tumor cells, which could potentially contribute to stratify MRD-positive patients. We investigated the prognostic value of those antigens required to monitor MRD in 1265 newly diagnosed patients enrolled in the GEM2000, GEM2005MENOS65, GEM2005MAS65 and GEM2010MAS65 protocols. Overall, CD19pos, CD27neg, CD38lo, CD45pos, CD81pos, CD117neg and CD138lo expression predicted inferior outcomes. Through principal component analysis, we found that simultaneous CD38lowCD81posCD117neg expression emerged as the most powerful combination with independent prognostic value for progression-free survival (HR:1.69; P=0.002). This unique phenotypic profile retained prognostic value among MRD-positive patients. We then used next-generation flow to determine antigen stability throughout the course of the disease, and found that the expression of antigens required to monitor MRD is mostly stable from diagnosis to MRD stages, except for CD81 whose expression progressively increased from baseline to chemoresistant tumor cells (14 vs 28%). Altogether, we showed that the phenotypic profile of tumor cells provides additional prognostic information, and could be used to further predict risk of relapse among MRD-positive patients.

Abstract
BACKGROUND AND OBJECTIVE Detection and labelling of an increment in the human stress level is a contribution focused principally on improving the quality of life of people. This work is aimed to develop a biophysical real-time stress identification and classification system, analysing two noninvasive signals, the galvanic skin response and the heart rate variability. METHODS An experimental procedure was designed and configured in order to elicit a stressful situation that is similar to those found in real cases. A total of 166 subjects participated in this experimental stage. The set of registered signals of each subject was considered as one experiment. A preliminary qualitative analysis of the signals collected was made, based on previous counselling received from neurophysiologists and psychologists. This study revealed a relationship between changes in the temporal signals and the induced stress states in each subject. To identify and classify such states, a subsequent quantitative analysis was performed in order to determine specific numerical information related to the above mentioned relationship. This second analysis gives the particular details to design the finally proposed classification algorithm, based on a Finite State Machine. RESULTS The proposed system is able to classify the detected stress stages at three levels: low, medium, and high. Furthermore, the system identifies persistent stress situations or momentary alerts, depending on the subject's arousal. The system reaches an F1 score of 0.984 in the case of high level, an F1 score of 0.970 for medium level, and an F1 score of 0.943 for low level. CONCLUSION The resulting system is able to detect and classify different stress stages only based on two non invasive signals. These signals can be collected in people during their monitoring and be processed in a real-time sense, as the system can be previously preconfigured. Therefore, it could easily be implemented in a wearable prototype that could be worn by end users without feeling to be monitored. Besides, due to its low computational, the computation of the signals slopes is easy to do and its deployment in real-time applications is feasible.

Abstract
Paracoccidioides brasiliensis and P. lutzii are fungi that cause paracoccidioidomycosis (PCM), the most prevalent systemic mycosis in South America. For serological diagnosis, although 43-kDa glycoprotein (gp43) is regarded as highly specific for PCM, the occurrence of false negative reactions in sera from patients infected with P. lutzii suggests that preparation with only one antigen is not recommended. Heat shock proteins are feasible alternatives as a second antigen because they are often highly immunogenic. In this study, we evaluated the usefulness of recombinant 60-kDa heat shock protein from P. brasiliensis (rPbHsp60) for the serological diagnosis of PCM. Using western blotting assay, we observed that 77.3% of the sera from PCM patients were positive to rPbHsp60, with 90.9% positivity to recombinant gp43 (rgp43). More importantly, sera from healthy subjects had 27% positivity to rPbHsp60 and none to rgp43. When rPbHsp60 was used in ELISA, we did not observe significant differences between the reactions with sera from PCM patients and healthy subjects, while the difference was clearly evident when the antigen was rgp43. Furthermore, rPbHsp60 was recognized by sera from patients with histoplasmosis, aspergillosis, sporotrichosis or tuberculosis in an ELISA test. These results show that rPbHsp60 is not a good antigen for PCM diagnosis.

Abstract
BACKGROUND The deficit of donor sites in major burns over 50% of the total body surface area has necessitated the application of methods besides traditional meshed autografting to achieve definitive skin cover. The Meek micrografting technique was introduced at this hospital in 2011, especially in the absence of a reliable source of deceased donor allograft skin. The purpose of this study was to evaluate this strategy with reference to its technical execution, efficacy and indications in the context of major paediatric burn surgery. METHODS A cohort study was performed of all paediatric patients with major burn who underwent Meek micrografting at a dedicated paediatric burn centre in a developing country over a five year period. Demographics, details of their burns, operative management and clinical course and outcomes were collected from patient records and operative notes and analysed. RESULTS Thirty-five patients were managed using the micrografting technique during the study period. The mean patient age was 4.1 years (range 3 months-11 years) and their mean total body surface area (TBSA) burn was 49.7% (range 15-86%). Eleven patients sustained inhalation injuries and five developed a re-feeding syndrome on account of delayed referral. The mean abbreviated burn severity index (ABSI) was 8.5 (range 2-13). The hospital length of stay in the 27 survivors was a mean of 75.5 days, equating to 1.4 days per percentage burn. Eight patients died during the course of treatment, with a mean TBSA burn of 67.75% (range 38-86%). Graft take one month after surgery was documented to be more than 90% in 24 patients, of whom 3 subsequently died. Eleven patients had less than 90% graft take at this time, of whom 5 died. CONCLUSION There is a considerable 'learning curve' associated with this technique. In order to achieve success one must ensure a completely viable, non-infected bed, obtained by tangential or fascial excision, followed by allografting as temporary coverage and to 'test the wound bed' for definitive coverage. Infection resulted in the majority of autograft loss in this series, and in addition to risk factors like burn size and inhalation injury, accounted for many of the deaths in this series. Meek micrografting offers high expansion ratios, thereby facilitating durable wound cover in the presence of limited donor sites. It is unlikely that a lethal dose, 50% (LD50) of almost 70% TBSA would have been possible in this context without the regular application of this technique. This study advocates for the widespread availability of Meek micrografting and deceased donor allograft skin in developing countries.

Abstract
There is a huge proliferation of surveillance systems that require strategies for detecting different kinds of stationary foreground objects (e.g., unattended packages or illegally parked vehicles). As these strategies must be able to detect foreground objects remaining static in crowd scenarios, regardless of how long they have not been moving, several algorithms for detecting different kinds of such foreground objects have been developed over the last decades. This paper presents an efficient and high-quality strategy to detect stationary foreground objects, which is able to detect not only completely static objects but also partially static ones. Three parallel nonparametric detectors with different absorption rates are used to detect currently moving foreground objects, short-term stationary foreground objects, and long-term stationary foreground objects. The results of the detectors are fed into a novel finite state machine that classifies the pixels among background, moving foreground objects, stationary foreground objects, occluded stationary foreground objects, and uncovered background. Results show that the proposed detection strategy is not only able to achieve high quality in several challenging situations but it also improves upon previous strategies.

Abstract
Colombian creole cattle have important adaptation traits related to heat tolerance and reproductive and productive efficiency. Romosinuano (ROMO) and Blanco Orejinegro (BON) are the most common breeds used by Colombian cattle breeders. Growth traits are of prime importance in these animals, which are mainly raised for beef production. Genes encoding growth hormone, growth hormone receptor, homeobox protein, insulin growth factor binding protein 3, leptin, and myostatin have been associated with physiological growth pathways in cattle and other species. We therefore aimed to identify single nucleotide polymorphisms (SNPs) within these genes in ROMO, BON, and Zebu cattle. DNA regions of these genes were sequenced in 386 animals; 47 new SNPs were found, of which 14 were located in the exonic regions, thereby changing the protein sequence. An association of SNPs with weaning weight (WW), daily weight gain at weaning (DWG), and weight at 16 months (W16M) traits was deduced. The genetic analysis revealed several SNPs related to these traits. The SNP GhRE06.2 had a significant association with WW and the SNP Lep03.4 was highly associated with DWG and W16M. Other polymorphisms were significantly associated with WW and DWG, although they did not surpass the Bonferroni significance threshold. The new mutations identified may indicate important points of genetic control in the DNA that could be responsible for changes in the expression of the analyzed traits. These SNPs might be used in future breeding programs to improve the productive performance of cattle in beef farms.
