Acute Hepatitis in Children Due to Rat Hepatitis E Virus.

Two of 11 children with acute hepatitis of unknown origin were found to have rat hepatitis E virus infection. This infection should be considered in the differential diagnosis of children with acute hepatitis of unknown origin.

Detection of Rat Hepatitis E Virus in Pigs, Spain, 2023.

We identified rat hepatitis E virus (HEV) RNA in farmed pigs from Spain. Our results indicate that pigs might be susceptible to rat HEV and could serve as viral intermediaries between rodents and humans. Europe should evaluate the prevalence of rat HEV in farmed pigs to assess the risk to public health.

Photodynamic therapy with BF-200 ALA gel for the treatment of actinic keratosis, Bowen´s disease and basal cell carcinoma in long term immunosuppressed patients after organ transplantation.

Continuous immunosuppression after organ transplantation is associated with an increased risk of developing keratinocyte neoplastic lesions. Topical photodynamic therapy represents a therapeutic approach for different keratinocyte neoplastic lesions. However, the specific efficacy and safety of this treatment in this immunocompromised population remains largely unknown. In this case report series, we show the efficacy and safety of photodynamic therapy with BF-200 ALA gel using red-light and daylight in immunocompromised patients. Out of 8 patients presented here, 1 was treated for 8 basal cell carcinomas, 1 for 2 Bowen´s disease lesions and 6 were treated for field cancerization including 4 to 10 actinic keratoses. Treatment response rates were above 75 %. The adverse events, including pain, did not differ from those already described for PDT. These data suggest that PDT with BF-200 ALA gel could be an effective and safe option to add to the treatment portfolio for neoplastic keratinocyte lesions in this high-risk population.

Quality of life in children with skin disease: A Spanish sample.

INTRODUCTION: The impact of skin diseases on quality of life varies widely, and some can have an impact similar to that of asthma or cystic fibrosis. MATERIAL AND METHODS: We conducted a cross-sectional, observational and descriptive study with the aim of describing the degree to which quality of life was affected in paediatric patients managed in a dermatology clinic by means of the Children's Dermatology Life Quality Index (CDLQI). RESULTS: In our study, the skin disease with the greatest impact on quality of life was atopic dermatitis, chiefly on account of symptoms like pruritus and insomnia. It was followed by acne, mainly due to the associated negative feelings (shame, sadness, etc.). Quality of life in patients with viral warts and molluscum contagiosum was mostly affected by the treatment, chiefly based on cryotherapy. Most patients with nevi or café-au-lait spots did not have a decreased quality of life, although up to one third of them had negative feelings in relation to their skin disease. DISCUSSION: Atopic dermatitis was the common skin disease that caused the greatest impairment in quality of life in our sample, although other diseases also had an impact on different dimensions of quality of life. We ought to underscore the recommendation to use less painful treatments than cryotherapy for viral warts and molluscum contagiosum, as the impairment in quality of life in paediatric patients with these conditions was mainly due to the treatment.

Real-world effectiveness and factors associated with increased mortality in non-critically ill patients with COVID-19 pneumonia receiving remdesivir.

OBJECTIVES: Evidence on the effectiveness of remdesivir when used in real-life clinical practice is controversial. This study aims to analyse its effectiveness and the factors associated with increased mortality in non-critically ill patients with COVID-19 pneumonia who require supplemental low-flow oxygen and received remdesivir. METHODS: A retrospective cohort study was conducted at Ramón y Cajal University Hospital (Madrid, Spain) which included all patients treated with remdesivir in our institution during the second pandemic breakout in Spain, from August to November 2020. Treatment with remdesivir was limited to non-critically ill patients with COVID-19 pneumonia requiring low-flow supplemental oxygen, with a treatment duration of 5 days. RESULTS: A total of 1757 patients were admitted with COVID-19 pneumonia during the study period, of which 281 non-critically ill patients were treated with remdesivir and included in the analysis. Mortality at 28 days after initiation of treatment was 17.1%. The median (IQR) time to recovery was 9 days (6-15). 104 (37.0%) patients had complications during hospitalisation, with renal failure being the most frequent (31 patients; 36.5%). After adjustment for confounding factors, high-flow oxygen therapy was associated with increased 28-day mortality (HR 2.77; 95% CI 1.39 to 5.53; p=0.004) and decreased 28-day clinical improvement (HR 0.54; 95% CI 0.35 to 0.85; p=0.008). A significant difference in survival and clinical improvement was identified between patients treated with high and low-flow oxygen. CONCLUSION: The 28-day mortality rate in patients treated with remdesivir needing low-flow oxygen therapy was higher than that published in clinical trials. Age and increased oxygen therapy needed after the beginning of treatment were the main risk factors associated with mortality.

The Impact of an Interactive Guidance Intervention on Sustained Social Withdrawal in Preterm Infants in Chile: Randomized Controlled Trial.

Background: Sustained social withdrawal is a key indicator of child emotional distress and a risk factor for psychological development. Preterm infants have a higher probability of developing sustained social withdrawal than infants born full-term during their first year. Objective: To compare the effect of a behavioral guidance intervention to that of routine pediatric care on sustained social withdrawal behavior in preterm infants. Design: Multicenter randomized clinical trial. Participants: Ninety nine moderate and late preterm newborns and their parents were recruited and randomized into two groups, i.e., Intervention (n = 49) and Control (n = 50). Both groups attended medical check-ups at 2, 6 and 12 months and were assessed with the Alarm Distress Baby Scale. The intervention group received a standardized behavioral intervention if the neonatologist detected sustained social withdrawal. Also, parents filled out the Edinburgh Postnatal Depression Scale, the modified-Perinatal Posttraumatic Stress Disorder Questionnaire, and the Impact of Event Scale-revised. Results: At baseline, the prevalence of withdrawal was 4.0% (95% CI: 0.03-14.2) for the control group and 22.4% (95% CI: 13.0-35.9) for the intervention group [OR = 0.22, p = 0.028 (95% CI =0.06-0.84)]. At 6 months, the prevalence was 10.0% (95% CI: 3.9-21.8) for the control group and 6.1% (95% CI: 2.1-16.5) for the intervention group [OR = 2.09, p = 0.318 (95% CI = 0.49-8.88)]. At 12 months, the prevalence was 22.0% (95% CI: 12.8-35.2) for the control group and 4.1% (95% CI: 1.1-13.7) for the intervention group [OR = 6.63, p = 0.018 (95% CI = 1.39-31.71)]. Logistic generalized estimating equation models were performed. The pooled crude OR (considering diagnosis at 6 and 12 months) was 3.54 [p = 0.022 (95% CI = 1.20-10.44); Cohen's d= 0.70]. In the case of pooled adjusted OR, the model considered diagnosis (0 = Withdrawal, 1 = Normal) as the dependent variable, time of evaluation (1= 6 months, 2 = 12 months) and group (0 = Control, 1 = Experimental) as factors. In this case, the pooled adjusted OR was 3.57 [p = 0.022 (95% CI = 1.20-10.65); Cohen's d = 0.70]. Conclusion: Assessment and intervention of sustained social withdrawal in preterm infants via standardized instruments benefits families by reducing its prevalence, and possible associated negative outcomes.

Multi-ancestry GWAS reveals excitotoxicity associated with outcome after ischaemic stroke.

During the first hours after stroke onset, neurological deficits can be highly unstable: some patients rapidly improve, while others deteriorate. This early neurological instability has a major impact on long-term outcome. Here, we aimed to determine the genetic architecture of early neurological instability measured by the difference between the National Institutes of Health Stroke Scale (NIHSS) within 6 h of stroke onset and NIHSS at 24 h. A total of 5876 individuals from seven countries (Spain, Finland, Poland, USA, Costa Rica, Mexico and Korea) were studied using a multi-ancestry meta-analyses. We found that 8.7% of NIHSS at 24 h of variance was explained by common genetic variations, and also that early neurological instability has a different genetic architecture from that of stroke risk. Eight loci (1p21.1, 1q42.2, 2p25.1, 2q31.2, 2q33.3, 5q33.2, 7p21.2 and 13q31.1) were genome-wide significant and explained 1.8% of the variability suggesting that additional variants influence early change in neurological deficits. We used functional genomics and bioinformatic annotation to identify the genes driving the association from each locus. Expression quantitative trait loci mapping and summary data-based Mendelian randomization indicate that ADAM23 (log Bayes factor = 5.41) was driving the association for 2q33.3. Gene-based analyses suggested that GRIA1 (log Bayes factor = 5.19), which is predominantly expressed in the brain, is the gene driving the association for the 5q33.2 locus. These analyses also nominated GNPAT (log Bayes factor = 7.64) ABCB5 (log Bayes factor = 5.97) for the 1p21.1 and 7p21.1 loci. Human brain single-nuclei RNA-sequencing indicates that the gene expression of ADAM23 and GRIA1 is enriched in neurons. ADAM23, a presynaptic protein and GRIA1, a protein subunit of the AMPA receptor, are part of a synaptic protein complex that modulates neuronal excitability. These data provide the first genetic evidence in humans that excitotoxicity may contribute to early neurological instability after acute ischaemic stroke.

Gas origin linked to paleo BSR.

The Central-South Chile margin is an excellent site to address the changes in the gas hydrate system since the last deglaciation associated with tectonic uplift and great earthquakes. However, the dynamic of the gas hydrate/free gas system along south central Chile is currently not well understood. From geophysical data and modeling analyses, we evaluate gas hydrate/free gas concentrations along a seismic line, derive geothermal gradients, and model past positions of the Bottom Simulating Reflector (BSR; until 13,000 years BP). The results reveal high hydrate/free gas concentrations and local geothermal gradient anomalies related to fluid migration through faults linked to seafloor mud volcanoes. The BSR-derived geothermal gradient, the base of free gas layers, BSR distribution and models of the paleo-BSR form a basis to evaluate the origin of the gas. If paleo-BSR coincides with the base of the free gas, the gas presence can be related to the gas hydrate dissociation due to climate change and geological evolution. Only if the base of free gas reflector is deeper than the paleo-BSR, a deeper gas supply can be invoked.

A cold seep triggered by a hot ridge subduction.

The Chile Triple Junction, where the hot active spreading centre of the Chile Rise system subducts beneath the South American plate, offers a unique opportunity to understand the influence of the anomalous thermal regime on an otherwise cold continental margin. Integrated analysis of various geophysical and geological datasets, such as bathymetry, heat flow measured directly by thermal probes and calculated from gas hydrate distribution limits, thermal conductivities, and piston cores, have improved the knowledge about the hydrogeological system. In addition, rock dredging has evidenced the volcanism associated with ridge subduction. Here, we argue that the localized high heat flow over the toe of the accretionary prism results from fluid advection promoted by pressure-driven discharge (i.e., dewatering/discharge caused by horizontal compression of accreted sediments) as reported previously. However, by computing the new heat flow values with legacy data in the study area, we raise the assumption that these anomalous heat flow values are also promoted by the eastern flank of the currently subducting Chile Rise. Part of the rift axis is located just below the toe of the wedge, where active deformation and vigorous fluid advection are most intense, enhanced by the proximity of the young volcanic chain. Our results provide valuable information to current and future studies related to hydrothermal circulation, seismicity, volcanism, gas hydrate stability, and fluid venting in this natural laboratory.

The Food Identity of Countries Differs Between Younger and Older Generations: A Cross-Sectional Study in American, European and Asian Countries.

Current generations have been strongly influenced by mass communication and massive immigration flows, which may change local lifestyles and perceptions of inhabitants towards traditional foods and beverages (TFBs). TFBs constitute a core element of the cultural identity of a country, although some of them are losing their appeal. In this study, the authors explored the TFBs perceptions of inhabitants in nine countries to determine if their food identity is changing by analysing the TFBs most frequently mentioned by different age cohorts within a country. Six countries were found to have a distinctive core of TFBs shared across age cohorts (homogenous), whereas the remaining showed a heterogeneous pattern. Correspondence and cluster analyses usually grouped younger generations together implying higher similarities among these cohorts. Furthermore, the binary logistic regression analyses performed identified significant differences in the probability of mentioning a specific TFBs across age cohorts per country. Data collected show younger cohorts focusing on TFBs categorised as snacks and foods on-the-go, whereas older cohorts more often refer to time-consuming savoury preparations. The results suggest that lifestyles and current societal trends in food consumption, for example, convenience and healthiness, are impacting the food culture and identity of countries, and therefore play an important role in the variation of TFBs perception and consumption between age cohorts within countries. The results obtained in this study could not only be used by food policymakers and nutritionists to distinguish the current trends that are reshaping the food identity and eating behaviours of the population but also to improve or develop new dietary strategies by age cohorts in the countries studied.

Current status of the rheumatologists' workforce in Latin America: a PANLAR collaborative study.

INTRODUCTION: Studies conducted by various scientific societies have shown that the demand for specialized rheumatology care is greater than the projected growth of the workforce. Our research aims to assess the current status of the rheumatology workforce in Latin America. METHOD: This is a descriptive, cross-sectional study. A survey was created on the RedCap platform. Data were analyzed with STATA 15® Software. We present descriptive analyses. The rate of inhabitants per rheumatologist was calculated using the number of rheumatologists practicing in each country and the inhabitants for year 2020. RESULTS: Our sample was composed by 19 PANLAR member countries in Latin America. Latin America has one rheumatologist per 106,838 inhabitants. The highest rate of rheumatologist per inhabitants was found in Uruguay (1 per 27,426 inhabitants), and the lowest was found in Nicaragua (1 per 640,648 inhabitants). Mean age was 51.59 (SD12.70), ranging between 28 and 96 years of age. Mean monthly compensation was USD $2382.6 (SD$1462.5). The country with lowest salary was Venezuela ($197), whereas the highest was Costa Rica ($4500). CONCLUSIONS: There is a high variability in rheumatologists' workforce characteristics in Latin America. These results could lead to policies aiming to increase the availability and income of rheumatologists, in order to increase opportunity and quality of care of patients living with rheumatic diseases. Key Points • The rheumatologists' workforce varies significantly among Latin American countries. • The supply of rheumatologists is insufficient for meeting the increasing need for specialists in this field.

Retrospective Comparison of Intranasal Fentanyl and Inhaled Nitrous Oxide to Intravenous Ketamine and Midazolam for Painful Orthopedic Procedures in a Pediatric Emergency Department.

OBJECTIVES: To compare the efficacy and adverse events of 2 pharmacological strategies: intranasal fentanyl and nitrous oxide (FN) inhaled against intravenous ketamine and midazolam (KM) as procedural sedation and analgesia (PSA) in painful orthopedic procedures in the pediatric emergency department (ED). METHODS: This is an observational retrospective cohort study. Patients were included that submitted to PSA for carrying out a painful orthopedic procedure in the ED of a tertiary hospital over a period of 2 years. The main outcome variable was efficacy and adverse events of the PSA procedure. RESULTS: Eighty-three patients were included. Fifty-two patients received FN and 31 KM. The PSA strategy was considered efficacious in 82.7% of the patients in the KM group and 80.6% in the FN cohort. No differences between both strategies were found (P = 0.815). Seventeen children showed early adverse events, 2 in the FN cohort and 15 in the KM group (relative risk of the KM strategy, 23.48; 95% confidence interval (CI), 3.24-169.99). The average of satisfaction obtained by the families was of 10 (CI, 10-10) in the KM cohort and of 9 (CI, 8-9.5) in the FN group (P = 0.152). The length of stay in the ED was longer in the KM cohort (P < 0.001). Hospital admission rate differences were not statistically different (9.6% vs 22.6%, P = 0.144) in the KM versus FN cohort. CONCLUSIONS: Both PSA strategies presented similar efficacy. The FN strategy was associated with a lower risk of adverse events and shorter ED length of stay than KM in this ED setting.

Gas hydrate versus seabed morphology offshore Lebu (Chilean margin).

Gas-hydrate occurrences along the Chilean margin have been widely documented, but the processes associated with fluid escapes caused by the dissociation of gas hydrates are still unknown. We report a seabed morphology growth related to fluid migration offshore Lebu associated with mud cones by analysing oxygen and deuterium stable water isotopes in pore water, bathymetric, biological and sedimentological data. A relief was observed at - 127 m water depth with five peaks. Enrichment values of δ18O (0.0-1.8‰) and δD (0.0-5.6‰) evidenced past hydrate melting. The orientation of the relief could be associated with faults and fractures, which constitute pathways for fluid migration. The benthic foraminifera observed can be associated with cold seep areas. We model that the mud cones correspond to mud growing processes related to past gas-hydrate dissociation. The integration of (i) the seismic data analysis performed in the surrounding area, (ii) the orientation of our studied relief, (iii) the infaunal foraminifera observed, (iv) the grain size and (v) the total organic matter and isotope values revealed that this area was formerly characterised by the presence of gas hydrates. Hence, this part of the Chilean margin represents a suitable area for investigating fluid-migration processes.

Multi-ancestry genetic study in 5,876 patients identifies an association between excitotoxic genes and early outcomes after acute ischemic stroke.

During the first hours after stroke onset neurological deficits can be highly unstable: some patients rapidly improve, while others deteriorate. This early neurological instability has a major impact on long-term outcome. Here, we aimed to determine the genetic architecture of early neurological instability measured by the difference between NIH stroke scale (NIHSS) within six hours of stroke onset and NIHSS at 24h (ΔNIHSS). A total of 5,876 individuals from seven countries (Spain, Finland, Poland, United States, Costa Rica, Mexico and Korea) were studied using a multi-ancestry meta-analyses. We found that 8.7% of ΔNIHSS variance was explained by common genetic variations, and also that early neurological instability has a different genetic architecture than that of stroke risk. Seven loci (2p25.1, 2q31.2, 2q33.3, 4q34.3, 5q33.2, 6q26 and 7p21.1) were genome-wide significant and explained 2.1% of the variability suggesting that additional variants influence early change in neurological deficits. We used functional genomics and bioinformatic annotation to identify the genes driving the association from each loci. eQTL mapping and SMR indicate that ADAM23 (log Bayes Factor (LBF)=6.34) was driving the association for 2q33.3. Gene based analyses suggested that GRIA1 (LBF=5.26), which is predominantly expressed in brain, is the gene driving the association for the 5q33.2 locus. These analyses also nominated PARK2 (LBF=5.30) and ABCB5 (LBF=5.70) for the 6q26 and 7p21.1 loci. Human brain single nuclei RNA-seq indicates that the gene expression of ADAM23 and GRIA1 is enriched in neurons. ADAM23 , a pre-synaptic protein, and GRIA1 , a protein subunit of the AMPA receptor, are part of a synaptic protein complex that modulates neuronal excitability. These data provides the first evidence in humans that excitotoxicity may contribute to early neurological instability after acute ischemic stroke. RESEARCH INTO CONTEXT: Evidence before this study: No previous genome-wide association studies have investigated the genetic architecture of early outcomes after ischemic stroke.Added Value of this study: This is the first study that investigated genetic influences on early outcomes after ischemic stroke using a genome-wide approach, revealing seven genome-wide significant loci. A unique aspect of this genetic study is the inclusion of all of the major ethnicities by recruiting from participants throughout the world. Most genetic studies to date have been limited to populations of European ancestry.Implications of all available evidence: The findings provide the first evidence that genes implicating excitotoxicity contribute to human acute ischemic stroke, and demonstrates proof of principle that GWAS of acute ischemic stroke patients can reveal mechanisms involved in ischemic brain injury.

Study about Food Choice Determinants According to Six Types of Conditioning Motivations in a Sample of 11,960 Participants.

Many aspects linked to personal characteristics, society and culture constitute some of the motivators that drive food choice. The aim of this work was to determine in what extent the eating behaviors of individuals are shaped by six different types of determinants, namely: health, emotions, price and availability, society and culture, environment and politics, and marketing and commercials. This is a descriptive cross-sectional study, involving a non-probabilistic sample of 11,960 participants from 16 countries. The objective of this work was to validate the questionnaire, so as to make it suitable for application in different contexts and different countries. For that, six scales were considered for validation by confirmatory factor analysis with structural equation modelling. The obtained results showed that the six individual scales evaluated presented good or very good fitting indices, with saturation in goodness-of-fit index in all cases. The values of chi-square ratio were 6.921 (for health), 0.987 (environment), 0.610 (emotions) and 0.000 in the remaining cases (convenience, society, marketing). Furthermore, the fit was perfect, with saturation for all indices, in three of the six models (convenience, society and marketing). The results of this wok allowed the validation of the six scales, and the assessing of different types of factors that can influence food choices and eating behaviors, namely in the categories: health, emotions, price and availability, society and culture, environment and politics, and marketing and commercials.
