CONSENSUS ON THE APPLICATION AND CARE OF BROMELAIN-BASED ENZYMATIC DEBRIDEMENT ON BURNS.

Treatment of burned patients involves early excision of the burn. The approach to this excision has changed since bromelain-based enzymatic debridement was introduced. This treatment option reduces complications from the surgical procedure and improves scar quality. It is indicated for partial and full thickness burns. It is important to agree on the nursing care before, during and after enzymatic debridement treatment to ensure an optimal preparation and maintenance of the wound bed for later treatment to be most successful. A multi-centre Delphi study was conducted with enzymatic debridement nursing care on burned patient experts. A coordinating group developed a 29-item questionnaire based on clinical guidelines and experience. Two question rounds were asked, reaching consensus on answers > 70%. Nine panellists from nine leading burns centres in Spain participated. The aim was to develop a national consensus on enzymatic debridement treatment based on clinical practice and evidence from almost 1500 cases. The experts reached 29 agreements on different aspects of treatment and patient condition: general considerations about the treatment, burned patient admission, treatment prior to enzymatic debridement, applying debridement, removing enzymatic debridement and the post-enzymatic debridement phase. The expert consensus on nursing care of the burn patient and application of bromelain-based enzymatic debridement includes general recommendations for the patient before, during and after application and the planning of localised care after debridement. This consensus document supports knowledge on enzymatic debridement technique, increasing safety in clinical nursing practice and ensuring successful treatment for the patient.

L'excision précoce est la référence dans le traitement des brûlures. Sa technique a été transformée par le débridement enzymatique à la bromélaïne. Cette technique, indiquée dans les brûlures intermédiaires et profondes, réduit les complications chirurgicales et améliore la qualité cicatricielle. La qualité des soins locaux, avant, pendant et après l'application de bromélaïne, est un paramètre important d'efficacité. Nous avons organisé une étude basée sur la méthode Delphi auprès de 9 experts de 9 CTB espagnols. Le groupe de coordination a réalisé un questionnaire à 29 items à partir des recommandations et de leur expérience (quasiment 1 500 cas au total). Deux séances ont été organisées, dans le but d'obtenir les agréments de plus de 70% des participants. Un consensus a été obtenu sur les 29 questions posées, se rapportant aux généralités, aux critères d'admission, au traitement avant bromélaïne, à son application, à son retrait et aux soins ultérieurs. Les recommandations de soins locaux consécutives recouvrent les phases avant, pendant et après utilisation. Elles permettent une amélioration de l'efficacité et de la sécurité du débridement enzymatique.

The associations between social support and mental health among Chinese immigrant pregnant and parenting women.

BACKGROUND: While it is recognized that social support can alleviate mental health symptoms, this relationship is not well-understood among Chinese pregnant and parenting immigrants in the United States. This study aims to bridge this gap by exploring the relationships between different types of social support and women's anxiety and depression, and examining how these associations vary with pregnancy status. METHODS: Data were obtained from a cross-sectional survey conducted in Simplified Chinese or Mandarin between March-June 2021 among 526 women who were pregnant and/or parenting a child under five years. The Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, Depression, and Social Support scales were used to measure anxiety, depression, and social support levels. Descriptive statistics, t-tests, chi-square tests, and Pearson's correlations were employed for analysis. Hierarchical regression was conducted to investigate the main and interaction effects of social support types and pregnancy status on mental health outcomes. RESULTS: Compared to non-pregnant women, pregnant women reported higher mean scores for anxiety (non-pregnant: 55, pregnant: 59, p < 0.01) and depression (non-pregnant: 54, pregnant: 56, p = 0.02). Instrumental support displayed a significant main effect in relation to anxiety (ß=-0.13, p = 0.01) and depression (ß=-0.16, p < 0.01); emotional support exhibited a significant main effect solely on depression (ß=-0.13, p = 0.01). Notably, the interaction effects between pregnancy status and both instrumental (ß=-0.28, p = 0.01) and emotional support (ß=-0.42, p < 0.01) were significant for anxiety. In contrast, informational support did not exhibit a significant impact on either anxiety or depression. CONCLUSIONS: The findings indicate that tailoring support to the cultural context is crucial, especially for pregnant women in this Chinese immigrant community, with instrumental and emotional support being particularly beneficial in mitigating maternal anxiety.

Isotropy of Cosmic Rays beyond 10

We report an estimation of the injected mass composition of ultrahigh energy cosmic rays (UHECRs) at energies higher than 10 EeV. The composition is inferred from an energy-dependent sky distribution of UHECR events observed by the Telescope Array surface detector by comparing it to the Large Scale Structure of the local Universe. In the case of negligible extragalactic magnetic fields (EGMFs), the results are consistent with a relatively heavy injected composition at E∼10 EeV that becomes lighter up to E∼100 EeV, while the composition at E>100 EeV is very heavy. The latter is true even in the presence of highest experimentally allowed extragalactic magnetic fields, while the composition at lower energies can be light if a strong EGMF is present. The effect of the uncertainty in the galactic magnetic field on these results is subdominant.

Sociopolitically and Trauma-Informed Public Health Practice With Latinx Families: Conceptual Framework and Best Practices.

Public health practitioners working with Latinx families in the United States must consider the historical contexts of colonization and slavery that have created conditions of violence, displacement, and social and economic marginalization throughout Latin America. Although shared experiences of colonization, dispossession, and migration affect all Latinxs, diverse national histories and sociopolitical contexts, migration patterns, and intersecting identities (e.g., gender, social class, race) complicate efforts to develop a uniform approach to this heterogeneous population. We provide a critical analysis of (1) how past experiences contribute to collective trauma and motivate migration, and (2) how these experiences are replicated in the United States through immigration-related adversities that deprive and threaten children and families through marginalization, fear of detention and deportation, and family separation brought on by a parent's deportation. This knowledge is imperative to advance research, practice, and policymaking with US Latinx populations. We provide best practice recommendations for a sociopolitically and trauma- informed public health workforce interfacing with Latinxs in the United States.

Perception of patients with retinal pathology on aspects of visual function and their management.

BACKGROUND AND OBJECTIVE: Age-related macular degeneration (AMD) and diabetic retinopathy (DR) are highly prevalent. OBJECTIVE: To explore perceptions of patients with AMD or DR about the impact of the disease and treatment on their daily living activities. MATERIALS AND METHODS: Semi-structured interviews with a questionnaire developed from validated patient reported outcomes questionnaires. The questionnaire consisted of 19 questions about the disease and 9 about the treatment. The questions (items) were answered on a scale from 1 to 9. In addition, the patient interviewed was invited to make free comments on each question. Nine patients with AMD and 9 with DR were interviewed by videoconference or telephone call. A quantitative analysis of the responses and a qualitative analysis of the comments were carried out. RESULTS: The most relevant item for patients with AMD or DR is "Recognize people when they are nearby", and "Read text in normal size font in a newspaper or book", followed, in patients with AMD, by "Do things what you would like" and, in patients with DR, "Feeling frustrated by the vision problems." Regarding the treatment, the most relevant aspects for both groups is that the treatment works and receiving appropriate information before and after the treatment. The qualitative comments were focused to the disease, the treatment, and to the role of doctors and the health system. CONCLUSION: Quantitative responses and free comments can be useful to improve the care of patients with AMD or DR by physicians and the health system.

[Usefulness of the Beck depression inventory in the diagnosis of depressive disorders in multiple sclerosis]. / Utilidad de la escala de depresión de Beck para el diagnóstico de los trastornos depresivos en la esclerosis múltiple.

INTRODUCTION: Depression is one of the most prevalent psychiatric conditions in adulthood, reaching figures of around 20%. The methodologies used to study depression are varied, and range from a self-administered test to structured psychiatric assessment. Several studies of patients with multiple sclerosis (MS) have been conducted in the last 20 years, and figures of around 35% have been found for depressive symptoms, while depressive disorders are less frequent, at approximately 21%. AIMS: The aim of this study is to evaluate the usefulness of patient self-reported scales such as the Beck depression inventory (BDI) for identifying depressive symptoms in patients with MS, and to analyse their correlation with the diagnosis of clinical depression or depressive disorder using the psychiatric clinical interview based on the criteria of the Diagnostic and statistical manual of mental disorders, fifth edition. PATIENTS AND METHODS: This is a multicentre descriptive cross-sectional study of patients with MS and depressive symptoms. The BDI and the Hamilton depression rating scale (HDRS) were used, and the patients with the highest scores underwent psychiatric assessment. RESULTS: A total of 191 patients were included; 81 of these (40.5%) had depressive symptomatology in the pathological range according to the BDI (cut-off point of 14), and 20 had a severe score (above 28). Nineteen patients with severe depressive symptoms according to both scales were selected and finally evaluated by a psychiatrist, who also assessed five patients who according to the neurologist had severe depressive symptoms despite a BDI score of almost 28, but did not reach that level. The suspected major depressive disorder was confirmed in only four (21%) cases with BDI scores indicative of severe symptoms. There is no correlation between the severity score as evidenced by the BDI and the psychiatric assessment. A major depressive disorder was diagnosed in 16 (66.6%) of the 24 patients with BDI > 26 evaluated by psychiatry. A score above 26 on the BDI enables identification of 75% of cases of depressive disorder without subtyping. The correlation between the HDRS and the BDI was statistically significant (r = 0.8; p < 0). CONCLUSIONS: The BDI is a useful screening test for identifying patients with depressive symptoms; in specific terms, a score above 26 is probably indicative of a depressive disorder that may benefit from psychiatric assessment.

La BDI es un test de cribado útil para identificar a pacientes con síntomas depresivos; en particular, una puntuación superior a 26 es indicativa con buena probabilidad de un trastorno depresivo que se podría beneficiar de una valoración psiquiátrica.

Enhancing immigrant families' mental health through the promotion of structural and community-based support.

Immigrant communities in the United States are diverse and have many assets. Yet, they often experience stressors that can undermine the mental health of residents. To fully promote mental health and well-being among immigrant communities, it is important to emphasize population-level policies and practices that may serve to mitigate stress and prevent mental health disorders. In this paper, we describe the stressors and stress experienced by immigrant families, using Sunset Park, Brooklyn as an example. We discuss ways to build structures and policies in support of equitable environments that promote mental health at the population level and enable families and their children to thrive.

Impact of the 2016 Presidential election and restrictive immigration climate on the work and wellbeing of Bangladeshi immigrant community frontline workers in New York City, U.S.A.

Community-based organizations (CBOs) are key players in mitigating the impact of restrictive policy changes on immigrant communities. The ability of these organizations to help diffuse the stress caused by restrictive, rapidly changing immigration policies depends, in part, on the capacity and health of their workforce. This study presents findings from a qualitative study conducted with 10 Bangladeshi community frontline workers working in various CBOs and advocacy organizations to understand their experience navigating a heightened anti-immigrant, anti-Muslim climate. Through thematic analyses, we inferred that the 2016 presidential election increased stress and mobilization among community frontline workers, with a meaningful distinction between participants working for immigration-focused institutions versus those in institutions where immigration issues were not the primary focus (e.g. health services, cultural programming). For those working in immigration-focused institutions, work burden increased due to challenges in managing misinformation, making sense of policy changes, and meeting the needs of families impacted by deportation. A toll on frontline workers' own physical health and mental health was discussed, as well as the need for culturally congruent mental health supports for the South Asian community.

Demonstration of event position reconstruction based on diffusion in the NEXT-white detector.

Noble element time projection chambers are a leading technology for rare event detection in physics, such as for dark matter and neutrinoless double beta decay searches. Time projection chambers typically assign event position in the drift direction using the relative timing of prompt scintillation and delayed charge collection signals, allowing for reconstruction of an absolute position in the drift direction. In this paper, alternate methods for assigning event drift distance via quantification of electron diffusion in a pure high pressure xenon gas time projection chamber are explored. Data from the NEXT-White detector demonstrate the ability to achieve good position assignment accuracy for both high- and low-energy events. Using point-like energy deposits from 83mKr calibration electron captures (E∼45 keV), the position of origin of low-energy events is determined to 2 cm precision with bias <1mm. A convolutional neural network approach is then used to quantify diffusion for longer tracks (E≥1.5 MeV), from radiogenic electrons, yielding a precision of 3 cm on the event barycenter. The precision achieved with these methods indicates the feasibility energy calibrations of better than 1% FWHM at Qßß in pure xenon, as well as the potential for event fiducialization in large future detectors using an alternate method that does not rely on primary scintillation.

Extended states in random dimer gated graphene superlattices.

Ordered and disordered semiconductor superlattices represent structures with completely opposed properties. For instance, ordered superlattices exhibit extended Bloch-like states, while disordered superlattices present localized states. These characteristics lead to higher conductance in ordered superlattices compared to disordered ones. Surprisingly, disordered dimer superlattices, which consist of two types of quantum wells with one type always appearing in pairs, exhibit extended states. The percentage of dissimilar wells does not need to be large to have extended states. Furthermore, the conductance is intermediate between ordered and disordered superlattices. In this work, we explore disordered dimer superlattices in graphene. We calculate the transmission and transport properties using the transfer matrix method and the Landauer-Büttiker formalism, respectively. We identify and discuss the main energy regions where the conductance of random dimer superlattices in graphene is intermediate to that of ordered and disordered superlattices. We also analyze the resonant energies of the double quantum well cavity and the electronic structure of the host gated graphene superlattice (GGSL), finding that the coupling between the resonant energies and the superlattice energy minibands gives rise to the extended states in random dimer GGSLs.

Intestinal inflammation marker calprotectin regulates epithelial intestinal zinc metabolism and proliferation in mouse jejunal organoids.

Calprotectin (CP), a heterodimer of S100A8 and S100A9, is expressed by neutrophils and a number of innate immune cells and is used widely as a marker of inflammation, particularly intestinal inflammation. CP is a ligand for toll-like receptor 4 (TLR4) and the receptor for advanced glycation end products (RAGE). In addition, CP can act as a microbial modulatory agent via a mechanism termed nutritional immunity, depending on metal binding, most notably Zn2+. The effects on the intestinal epithelium are largely unknown. In this study we aimed to characterize the effect of calprotectin on mouse jejunal organoids as a model epithelium, focusing on Zn2+ metabolism and cell proliferation. CP addition upregulated the expression of the Zn2+ absorptive transporter Slc39a4 and of methallothionein Mt1 in a Zn2+-sensitive manner, while downregulating the expression of the Zn2+ exporter Slc30a2 and of methallothionein 2 (Mt2). These effects were greatly attenuated with a CP variant lacking the metal binding capacity. Globally, these observations indicate adaptation to low Zn2+ levels. CP had antiproliferative effects and reduced the expression of proliferative and stemness genes in jejunal organoids, effects that were largely independent of Zn2+ chelation. In addition, CP induced apoptosis modestly and modulated antimicrobial gene expression. CP had no effect on epithelial differentiation. Overall, CP exerts modulatory effects in murine jejunal organoids that are in part related to Zn2+ sequestration and partially reproduced in vivo, supporting the validity of mouse jejunal organoids as a model for mouse epithelium.

The influence of age, period, and cohort factors on the incidence of kidney cancer in Spain 1990-2019: Evidence from the global burden of disease study.

OBJECTIVE: This study aimed to assess the influence of age, period, and cohort (A-P-C) factors on kidney cancer (KC) incidence trends in Spain from 1990 to 2019. METHODS: Employing data from the Global Burden of Disease Study 2019, we employed joinpoint analysis to determine long-term patterns and A-P-C modelling to quantify net drift, local drift, longitudinal age curves, and rate ratios (RRs) of period and cohort effects. RESULTS: Over the period 1990-2019, an estimated 142,811 cases of KC were diagnosed in Spain. A consistent upward trend in KC incidence was observed for both men and women, with the male-to-female ratio remaining stable at 2.6. Joinpoint analysis identified three distinct periods for men: An initial period (1990-1995) characterised by a significant increase in rates, a subsequent period (1995-2016) characterised by a slowdown in the rate of increase, and a final period (2016-2019) in which rates have plateaued. In women, 2 time periods were observed: an initial period (1990-2007) in which rates increased significantly, followed by a period of stabilization (2007-2019). Men born in the early-mid 20th century had a rising KC risk, peaking in the 1960s. Women's risk rose steadily, peaking in the late 1990s. CONCLUSION: A-P-C analysis reveals steady KC incidence increase in both genders over three decades. This highlights the need for targeted public health policies and effective prevention strategies.

Adaptive laboratory evolution of Clostridium autoethanogenum to metabolize CO2 and H2 enhances growth rates in chemostat and unravels proteome and metabolome alterations.

Gas fermentation of CO2 and H2 is an attractive means to sustainably produce fuels and chemicals. Clostridium autoethanogenum is a model organism for industrial CO to ethanol and presents an opportunity for CO2-to-ethanol processes. As we have previously characterized its CO2/H2 chemostat growth, here we use adaptive laboratory evolution (ALE) with the aim of improving growth with CO2/H2. Seven ALE lineages were generated, all with improved specific growth rates. ALE conducted in the presence of 2% CO along with CO2/H2 generated Evolved lineage D, which showed the highest ethanol titres amongst all the ALE lineages during the fermentation of CO2/H2. Chemostat comparison against the parental strain shows no change in acetate or ethanol production, while Evolved D could achieve a higher maximum dilution rate. Multi-omics analyses at steady state revealed that Evolved D has widespread proteome and intracellular metabolome changes. However, the uptake and production rates and titres remain unaltered until investigating their maximum dilution rate. Yet, we provide numerous insights into CO2/H2 metabolism via these multi-omics data and link these results to mutations, suggesting novel targets for metabolic engineering in this bacterium.

Ion uptake in naturally acidic water.

The first studies on ion regulation in fish exposed to low pH, which were inspired by the Acid Rain environmental crisis, seemed to indicate that ion transport at the gills was completely and irreversibly inhibited at pH 4.0-4.5 and below. However, work on characid fish native to the Rio Negro, a naturally acidic, blackwater tributary of the Amazon River, found that they possess ion transport mechanisms that are completely insensitive to pHs as low as 3.25. As more species were examined it appeared that pH-insensitive transport was a trait shared by many, if not most, species in the Order Characiformes. Subsequently, a few other species of fish have been shown to be able to transport ions at low pH, in particular zebrafish (Danio rerio), which show rapid recovery of Na+ uptake at pH 4.0 after initial inhibition. Measurements of rates of Na+ transport during exposure to pharmacological agents that inhibit various transport proteins suggested that characiform fish do not utilize the generally accepted mechanisms for Na+ transport that rely on some form of H+ extrusion. Examination of zebrafish transport at low pH suggest the rapid recovery may be due to a novel Na+/K+ exchanger, but after longer term exposure they may rely on a coupling of Na+/H+ exchangers and NH3 excretion. Further work is needed to clarify these mechanisms of transport and to find other acid-tolerant species to fully gain an appreciation of the diversity of physiological mechansisms involved.

Electroporación irreversible: ampliando las fronteras de la ablación / Irreversible electroporation: Beyond the limits of tumor ablation

La electroporación irreversible o IRE (irreversible electroporation) es una técnica de ablación tumoral no térmica basada en la aplicación de pulsos eléctricos de alto voltaje entre pares de agujas insertadas alrededor de un tumor. La corriente generada favorece la creación de nanoporos en la membrana plasmática, desencadenando la apoptosis. Por ello, la IRE puede utilizarse de manera segura en localizaciones cercanas a estructuras vasculares delicadas, contraindicadas para el resto de técnicas termoablativas. Actualmente la IRE se emplea con éxito para la ablación de tumores en páncreas, riñón e hígado y, de manera muy extendida, como opción terapéutica focal para el cáncer de próstata. La necesidad de un manejo anestésico específico y la colocación precisa y en paralelo de múltiples agujas implican un alto nivel de complejidad, siendo necesaria una gran experiencia del equipo intervencionista. No obstante, se trata de una técnica muy prometedora con una gran capacidad inmunológica sistémica que puede provocar un efecto a distancia del tumor tratado (efecto abscopal).(AU)

Irreversible electroporation (IRE) is a non-thermal tumor ablation technique. High-voltage electrical pulses are applied between pairs of electrodes inserted around and/or inside a tumor. The generated electric current induces the creation of nanopores in the cell membrane, triggering apoptosis. As a result, IRE can be safely used in areas near delicate vascular structures where other thermal ablation methods are contraindicated. Currently, IRE has demonstrated to be a successful ablation technique for pancreatic, renal, and liver tumors and is widely used as a focal therapeutic option for prostate cancer. The need for specific anesthetic management and accurate parallel placement of multiple electrodes entails a high level of complexity and great expertise from the interventional team is required. Nevertheless, IRE is a very promising technique with a remarkable systemic immunological capability and may impact on distant metastases (abscopal effect).(AU)
