Knowledge about their distribution, abundance, evolution, structural organization, transcriptional regulation, fundamental roles in free life, pathogenesis, and bacteria-plant interaction has been generated. This review focuses on these aspects and provides a current picture of LTTR biology.

[Impact of days elapsed from the onset of symptoms to hospitalization in COVID-19 in-hospital mortality: Time matters]. / Impacto de los días transcurridos desde el inicio de los síntomas hasta la hospitalización en la mortalidad hospitalaria por COVID-19: el tiempo importa.

Background: COVID-19 shows different clinical and pathophysiological stages over time. Theeffect of days elapsed from the onset of symptoms (DEOS) to hospitalization on COVID-19prognostic factors remains uncertain. We analyzed the impact on mortality of DEOS to hospital-ization and how other independent prognostic factors perform when taking this time elapsedinto account. Methods: This retrospective, nationwide cohort study, included patients with confirmed COVID-19 from February 20th and May 6th, 2020. The data was collected in a standardized online datacapture registry. Univariate and multivariate COX-regression were performed in the generalcohort and the final multivariate model was subjected to a sensitivity analysis in an earlypresenting (EP; < 5 DEOS) and late presenting (LP; ≥5 DEOS) group. Results: 7915 COVID-19 patients were included in the analysis, 2324 in the EP and 5591 in theLP group. DEOS to hospitalization was an independent prognostic factor of in-hospital mortalityin the multivariate Cox regression model along with other 9 variables. Each DEOS incrementaccounted for a 4.3% mortality risk reduction (HR 0.957; 95% CI 0.93---0.98). Regarding variationsin other mortality predictors in the sensitivity analysis, the Charlson Comorbidity Index onlyremained significant in the EP group while D-dimer only remained significant in the LP group. Conclusion: When caring for COVID-19 patients, DEOS to hospitalization should be consideredas their need for early hospitalization confers a higher risk of mortality. Different prognosticfactors vary over time and should be studied within a fixed timeframe of the disease.

Impacto de los días transcurridos desde el inicio de los síntomas hasta la hospitalización en la mortalidad hospitalaria por COVID-19: el tiempo importa / Impact of days elapsed from the onset of symptoms to hospitalization in COVID-19 in-hospital mortality: Time matters

Antecedentes La COVID-19 muestra diferentes fases clínicas y fisiopatológicas a lo largo del tiempo. El efecto de los días transcurridos desde el comienzo de los síntomas (DTCS) hasta la hospitalización sobre los factores pronósticos de la COVID-19 sigue siendo incierto. Analizamos el impacto en la mortalidad de los DTCS hasta la hospitalización y cómo se comportan otros factores pronósticos independientes al tener en cuenta dicho tiempo transcurrido. Métodos En este estudio de cohortes nacional retrospectivo se incluyó a pacientes con COVID-19 confirmada entre el 20 de febrero y el 6 de mayo de 2020. Los datos se recopilaron en un registro normalizado de captura de datos en línea. Se realizó una regresión de Cox uni y multifactorial en la cohorte general y el modelo multifactorial final se sometió a un análisis de sensibilidad en un grupo de presentación precoz (PP) < 5 DTCS y otro de presentación tardía (PT) ≥ 5 DTCS). Resultados En el análisis se incluyó a 7.915 pacientes con COVID-19, 2.324 en el grupo de PP y 5.591 en el de PT. Los DTCS hasta la hospitalización fueron un factor pronóstico independiente de mortalidad intrahospitalaria en el modelo de regresión de Cox multifactorial junto con otras nueve variables. Cada incremento en un DTCS supuso una reducción del riesgo de mortalidad del 4,3% (RRI = 0,957; IC 95%, 0,93-0,98). En cuanto a las variaciones de otros factores predictivos de la mortalidad en el análisis de sensibilidad, únicamente el índice de comorbilidad de Charlson siguió siendo significativo en el grupo de PP, mientras que únicamente el dímero D lo siguió siendo en el grupo de PT. Conclusiones Al atender a pacientes con COVID-19 hay que tener en cuenta los DTCS hasta la hospitalización porque la necesidad de hospitalización precoz confiere un mayor riesgo de mortalidad. Los diferentes factores pronósticos varían con el tiempo y deberían estudiarse dentro de un marco temporal fijo de la enfermedad (AU)

Disfunción eréctil en pacientes con EPOC. Una revisión sistemática y metaanálisis / Erectile dysfunction in patients with COPD. A systematic review and meta-analysis

Introducción Los estudios sobre sexualidad en pacientes con enfermedad pulmonar obstructiva crónica (EPOC) son escasos y han arrojado resultados contradictorios. Nuestro objetivo fue determinar la prevalencia de disfunción eréctil (DE) y los factores asociados en pacientes con EPOC. Métodos Se buscaron artículos con datos sobre prevalencia de DE en pacientes diagnosticados de EPOC mediante espirometría en las bases de datos PubMed, Embase, Cochrane Library y Biblioteca Virtual de Salud, desde el año desde su creación hasta el 31 de enero de 2021. La prevalencia de DE se valoró con una media ponderada de los estudios. Se realizó un metaanálisis con el modelo de efectos fijos de Peto para valorar la asociación de EPOC con DE. Resultados Se incluyeron finalmente 15 estudios. La prevalencia ponderada de DE fue de 74,6%. Un metaanálisis con cuatro estudios y 519 individuos mostró una asociación de EPOC con DE (odds ratio ponderado estimado de 2,89, IC 95% 1,93-4,32, p < 0,001), con un grado de heterogeneidad no desdeñable (I2 57%). En la revisión sistemática, la edad, el tabaquismo, el grado de obstrucción, la saturación de oxígeno y el estado de salud previo se asociaron con mayor prevalencia de DE. Concusiones La DE es frecuente en los pacientes con EPOC y su prevalencia es mayor que en la población general (AU)

Introduction Studies on sexuality in patients with chronic obstructive pulmonary disease (COPD) are scarce and have yielded conflicting results. Our aim was to determine the prevalence of erectile dysfunction (ED) and associated factors in patients with COPD. Methods Articles with data on ED prevalence in patients diagnosed with COPD through spirometry were searched for in the PubMed, Embase, Cochrane Library, and Virtual Health Library databases from the year of their creation until January 31, 2021. The prevalence of ED was assessed with a weighted mean of the studies. A meta-analysis was performed using the Peto fixed-effect model to evaluate the association of COPD with ED. Results Fifteen studies were ultimately included. The weighted prevalence of ED was 74.6%. A meta-analysis with four studies and 519 individuals showed an association of COPD with ED (estimated weighted odds ratio 2.89, 95% CI 1.93-4.32, p < 0.001), with a non-negligible degree of heterogeneity (I2 57%). In the systematic review, age, smoking, degree of obstruction, oxygen saturation, and previous health status were associated with a higher prevalence of ED. Conclusions ED is common in patients with COPD and its prevalence is higher than in the general population (AU)

Effect of calcium oxalate crystals on the micromechanical properties of sclerenchyma tissue from the pecan nutshell (Carya illinoinensis).

The objective of this study was to evaluate the effect of the presence of calcium oxalate (CaOx) crystals on the micromechanical properties of sclerenchyma tissue from the pecan nutshell (Carya illinoinensis). The microstructure of the cross-section nutshell was examined using light microscopy (LM) and atomic force microscopy (AFM). Using an instrumented indentation system, indentation tests with maximum loads of 500 mN were made on the biological material where the variables studied were the number of crystals present in the evaluated area and the size of individual crystals. Microscopic analysis revealed that the pecan nutshell consists of sclerenchyma tissue with multiple CaOx crystals randomly distributed throughout the material, exhibiting prismatic shapes and various sizes. The results of the indentation tests showed that the examined areas where there were crystals (1, 2 or up to 3) presented values of hardness and elastic modulus significantly higher (P < 0.05) compared to the sclerenchyma (without crystals). Likewise, there were no significant differences (P > 0.05) between the values of the micromechanical properties of the areas evaluated as a function of the number of crystals. On the other hand, it was observed that the size of the crystals did not show a direct correlation with the mechanical properties evaluated as expected. In conclusion, the biomineralization phenomenon is a successful strategy designed by nature to improve the rigidity of the pecan nutshell, where the CaOx crystals strengthen the structure by increasing the micromechanical properties.

Characterization and Outcomes in Patients Treated With Apremilast in Routine Clinical Practice in Spain: Results From the APPRECIATE Study. / Caracterización y resultados de pacientes tratados con apremilast en la práctica clínica habitual española: resultados del estudio APPRECIATE.

BACKGROUND AND OBJECTIVES: It is necessary to expand the knowledge in the use of apremilast in clinical practice. The APPRECIATE study (NCT02740218) aims to describe the characteristics of patients with psoriasis treated with apremilast, to evaluate their perspectives and those of dermatologists, as well as the outcomes obtained in clinical practice in Spain. METHODS: Observational, retrospective, cross-sectional, multicenter study of patients with chronic plaque psoriasis who could be contacted 6 (±1) months after apremilast initiation. The data were obtained from medical records and questionnaires from patients and physicians. RESULTS: A total of 80 patients were evaluated; at apremilast onset, they showed mean (standard deviation, SD) Psoriasis Area and Severity Index (PASI) = 8.3 (5.3), mean (SD) Dermatology Life Quality Index (DLQI) = 8.9 (6.6). At six months, 58.8% (n=47) of patients continued apremilast treatment (discontinuations due to lack of efficacy [16.3%], safety/tolerability [20.0%]). In patients continuing treatment, PASI75 was achieved by 36.7% of patients; mean (95% CI) DLQI score was 2.2 (0.7-3.6) and mean (SD) Patient Benefit Index score was 2.8 (0.8). Compliance with physicians' expectations was correlated with benefits reported by patients (r=0.636). Adverse events were reported by 56.3% of patients (the most common were diarrhoea and nausea). CONCLUSIONS: Patients receiving apremilast for 6 months in Spanish clinical practice, reported substantial improvements in their quality of life (mean DLQI reduced by more than 6 points) and disease severity (PASI75 achieved by over one-third of patients), despite less skin involvement than patients who enrolled in clinical trials.

Shaping quantum photonic states using free electrons.

It is a long-standing goal to create light with unique quantum properties such as squeezing and entanglement. We propose the generation of quantum light using free-electron interactions, going beyond their already ubiquitous use in generating classical light. This concept is motivated by developments in electron microscopy, which recently demonstrated quantum free-electron interactions with light in photonic cavities. Such electron microscopes provide platforms for shaping quantum states of light through a judicious choice of the input light and electron states. Specifically, we show how electron energy combs implement photon displacement operations, creating displaced-Fock and displaced-squeezed states. We develop the theory for consecutive electron-cavity interactions with a common cavity and show how to generate any target Fock state. Looking forward, exploiting the degrees of freedom of electrons, light, and their interaction may achieve complete control over the quantum state of the generated light, leading to novel light statistics and correlations.

Aqueous extract of pomegranate enriched in ellagitannins prevents anxiety-like behavior and metabolic changes induced by cafeteria diet in an animal model of menopause.

Women around menopause are vulnerable to present psychiatric and metabolic disorders; thus, therapies that contribute to treat both pathologies are required. Previous reports showed that an aqueous extract of pomegranate (Punica granatum), enriched in ellagitannins, exerts an antidepressant-like effect in ovariectomized rats. We analyze whether this aqueous extract of P. granatum (AE-PG) prevents the anxiety-like behavior induced by a cafeteria diet (CAF) in middle-aged ovariectomized rats at the same time that it prevents an increase in body weight, glucose, lipids, and the changes on mRNA expression of the peroxisome proliferator-activated receptor-gamma (PPAR-γ) in the liver. Also, the effects of AE-PG on the protein levels of PPAR-γphospho-PPAR-γ, extracellular signal-regulated protein kinase (ERK1/2) and phospho-ERK1/2 were measured in the hippocampus and amygdala. CAF induced anxiety-like behavior, augmented lipids and glucose blood levels, body weight, visceral fat, insulin resistance, and decreased mRNA expression of PPAR-γ in the liver. In rats fed with the CAF, AE-PG prevented the anxiety-like behavior, reduced body weight, lowered lipid levels, reduced insulin resistance, and increased PPAR-γ mRNA expression in the liver. In the hippocampus, ERK1/2 but not PPAR-γ protein levels were decreased by CAF, while AE-PG prevented these effects. In the amygdala, CAF increased the phosphorylation of PPARγ, and AE-PG prevented it. In contrast, AE-PG rescued the decreased ERK1/2 protein level in the hippocampus caused by CAF. In conclusion, AE-PG treatment prevented anxiogenic and metabolic effects induced by CAF, and its effects appear to be mediated by ERK1/2 and PPARγ depending on the brain area studied.

Changes in lung immune cells related to clinical outcome during treatment with infliximab for sarcoidosis.

Pulmonary sarcoidosis is characterized by an exaggerated CD4+ T cell response and formation of non-necrotizing granulomas. Tumour necrosis factor α (TNF-α) is regarded as crucial for granuloma formation and TNF-α inhibitors offer a third-line treatment option for patients not responding to conventional treatment. However, not all patients benefit from treatment, and an optimal dose and treatment duration have not been established. Insight into the influence of TNF-α inhibitors on lung immune cells may provide clues as to what drives inflammation in sarcoidosis and improve our understanding of treatment outcomes. To evaluate the effects of treatment with the TNF-α inhibitor infliximab on lung immune cells and clinical features of the patients, 13 patients with sarcoidosis refractory to conventional treatment were assessed with bronchoalveolar lavage (BAL), spirometry and computerized tomography (CT) scan closely adjacent to the start of infliximab treatment. These investigations were repeated after 6 months of treatment. Treatment with TNF-α inhibitor infliximab was well tolerated with no adverse events, except for one patient who developed a probable adverse event with liver toxicity. Ten patients were classified as responders, having a reduced CD4/CD8 ratio, a decreased percentage of CD4+ T cells expressing the activation marker CD69 and number of mast cells (P < 0·05 for all). The percentage of T regulatory cells (Tregs ), defined as forkhead box P3+ CD4+ T cells decreased in most patients. In conclusion, six months of infliximab treatment in patients with sarcoidosis led to signs of decreased CD4+ T cell alveolitis and decreased mastocytosis in the lungs of responders.

Addition of milk fat globule membrane-enriched supplement to a high-fat meal attenuates insulin secretion and induction of soluble epoxide hydrolase gene expression in the postprandial state in overweight and obese subjects.

CVD and associated metabolic diseases are linked to chronic inflammation, which can be modified by diet. The objective of the present study was to determine whether there is a difference in inflammatory markers, blood metabolic and lipid panels and lymphocyte gene expression in response to a high-fat dairy food challenge with or without milk fat globule membrane (MFGM). Participants consumed a dairy product-based meal containing whipping cream (WC) high in saturated fat with or without the addition of MFGM, following a 12 h fasting blood draw. Inflammatory markers including IL-6 and C-reactive protein, lipid and metabolic panels and lymphocyte gene expression fold changes were measured using multiplex assays, clinical laboratory services and TaqMan real-time RT-PCR, respectively. Fold changes in gene expression were determined using the Pfaffl method. Response variables were converted into incremental AUC, tested for differences, and corrected for multiple comparisons. The postprandial insulin response was significantly lower following the meal containing MFGM (P < 0·01). The gene encoding soluble epoxide hydrolase (EPHX2) was shown to be more up-regulated in the absence of MFGM (P = 0·009). Secondary analyses showed that participants with higher baseline cholesterol:HDL-cholesterol ratio (Chol:HDL) had a greater reduction in gene expression of cluster of differentiation 14 (CD14) and lymphotoxin ß receptor (LTBR) with the WC+MFGM meal. The protein and lipid composition of MFGM is thought to be anti-inflammatory. These exploratory analyses suggest that addition of MFGM to a high-saturated fat meal modifies postprandial insulin response and offers a protective role for those individuals with higher baseline Chol:HDL.

Seroprevalence of selected transfusion transmissible infections among blood donors in Region 3, Philippines: A 5-year retrospective study.

Transfusion of blood is a life-saving intervention that saves many lives. Unsafe practices in blood donation and pre-transfusion testing place people's lives at risk of transfusion transmissible infections (TTIs). The study aims to determine the overall seroprevalence of the selected TTIs for the past 5 years (2013-2017) among blood donors from a hospital in Region 3, Philippines. The trend and distribution of the TTIs according to age group, sex, donor category, and number of donations were also determined. Data extracted include the age, sex, donor category, number of donations, and screening results of all donors from January 2013 to December 2017. The overall seroprevalence of the selected TTIs from over the 5-year period is 4.17%. The seroprevalence rates of hepatitis B, hepatitis C, HIV and syphilis from 2013 to 2017 are 2.87%, 0.48%, 0.10%, and 0.62%, respectively. The age group of 25 to 44 years old showed the highest rate of reactive donors. Also, higher rates of reactive donors are seen among male donors, replacement donors, and first-time donors. The overall seroprevalence of TTIs in the study locale is low and it shows a decreasing trend from 2013 to 2017. Donors who are 25 to 44 years old, males, replacement, and first-time donors showed highest seroprevalence rates of TTIs.

A GWAS meta-analysis from 5 population-based cohorts implicates ion channel genes in the pathogenesis of irritable bowel syndrome.

BACKGROUND: Irritable bowel syndrome (IBS) shows genetic predisposition, however, large-scale, powered gene mapping studies are lacking. We sought to exploit existing genetic (genotype) and epidemiological (questionnaire) data from a series of population-based cohorts for IBS genome-wide association studies (GWAS) and their meta-analysis. METHODS: Based on questionnaire data compatible with Rome III Criteria, we identified a total of 1335 IBS cases and 9768 asymptomatic individuals from 5 independent European genotyped cohorts. Individual GWAS were carried out with sex-adjusted logistic regression under an additive model, followed by meta-analysis using the inverse variance method. Functional annotation of significant results was obtained via a computational pipeline exploiting ontology and interaction networks, and tissue-specific and gene set enrichment analyses. KEY RESULTS: Suggestive GWAS signals (P ≤ 5.0 × 10-6 ) were detected for 7 genomic regions, harboring 64 gene candidates to affect IBS risk via functional or expression changes. Functional annotation of this gene set convincingly (best FDR-corrected P = 3.1 × 10-10 ) highlighted regulation of ion channel activity as the most plausible pathway affecting IBS risk. CONCLUSION & INFERENCES: Our results confirm the feasibility of population-based studies for gene-discovery efforts in IBS, identify risk genes and loci to be prioritized in independent follow-ups, and pinpoint ion channels as important players and potential therapeutic targets warranting further investigation.

Phenotypic evaluation of ESBL- and carbapenemaseproducing Escherichia coli and Klebsiella pneumoniae from a teaching hospital in the Philippines.

Antimicrobial resistance is a worldwide public health concern. Rise in the number of antimicrobial resistant organisms, such as extended spectrum ß-lactamase- (ESBL) and carbapenemase-producing Escherichia coli and Klebsiella pneumoniae, continue to burden millions of people worldwide. E. coli and K. pneumoniae were isolated and collected for four months from a teaching hospital in the Philippines. All isolates were subjected to ESBL and carbapenemase testing using the double disk synergy test and modified Hodge test, respectively. Their pattern of resistance among different classes of antimicrobial agents was also investigated using the Kirby-Bauer disk diffusion test. Among the 32 clinical isolates tested, 28.1% were positive for ESBL production and 6.3% were positive for carbapenemase production. Species-specific classification showed that E. coli (44.4%) has the highest rate of ESBL production whereas both E. coli (5.6%) and K. pneumoniae (7.1%) showed almost similar rates of carbapenemase production. Antimicrobial resistance pattern of drug resistant isolates showed that all organisms were resistant to ampicillin, and majority showed resistance towards ciprofloxacin, cefotaxime, ceftriaxone, and sulfamethoxazole/trimethoprim. ESBL production is seen highest among E. coli isolates while similar rates of carbapenemase production was observed to both E. coli and K. pneumoniae isolates. Overall, antimicrobial resistance continues to rise and poses a huge threat in public health worldwide. Efforts should be made in developing rapid tests for antimicrobial resistance and to search for effective treatment from infections caused by multidrug resistant organisms.
