Marine picoplankton metagenomes and MAGs from eleven vertical profiles obtained by the Malaspina Expedition.

The Ocean microbiome has a crucial role in Earth's biogeochemical cycles. During the last decade, global cruises such as Tara Oceans and the Malaspina Expedition have expanded our understanding of the diversity and genetic repertoire of marine microbes. Nevertheless, there are still knowledge gaps regarding their diversity patterns throughout depth gradients ranging from the surface to the deep ocean. Here we present a dataset of 76 microbial metagenomes (MProfile) of the picoplankton size fraction (0.2-3.0 µm) collected in 11 vertical profiles covering contrasting ocean regions sampled during the Malaspina Expedition circumnavigation (7 depths, from surface to 4,000 m deep). The MProfile dataset produced 1.66 Tbp of raw DNA sequences from which we derived: 17.4 million genes clustered at 95% sequence similarity (M-GeneDB-VP), 2,672 metagenome-assembled genomes (MAGs) of Archaea and Bacteria (Malaspina-VP-MAGs), and over 100,000 viral genomic sequences. This dataset will be a valuable resource for exploring the functional and taxonomic connectivity between the photic and bathypelagic tropical and sub-tropical ocean, while increasing our general knowledge of the Ocean microbiome.

[Sense of coherence in breastfeeding women: A scoping review].

BACKGROUND: The establishment of breastfeeding may sometimes be stressful. We aimed to analyze the sense of coherence in lactating women to determine the general resistance resources during lactation and the professional interventions that promote a high sense of coherence. METHODS: A search of studies in English, Spanish, or Portuguese on lactating women's sense of coherence was carried out in PubMed, PsycINFO, ScienceDirect, and CINAH databases published between May and November 2022. Study quality and risk of bias were examined according to ICROMS and STROBE criteria. RESULTS: We identified 316 studies, of which eight -all of adequate quality- were included, three qualitative and five quantitative. A high level of maternal sense of coherence was related to longer duration, self-efficacy, attachment, and enjoyment of the breastfeeding experience. The main general resistance resources were to receive social support, particularly from partners, mothers, and health professionals. The interventions that favored the sense of coherence were mainly those related to a close, empathic, personalized, comprehensive, and family-centered professional support. CONCLUSIONS: The detection of the level of sense of coherence in lactating mothers may help identify women with a higher risk of weaning and establish professional intervention strategies that improve the breastfeeding experience.

Sentido de coherencia en mujeres lactantes: una revisión de alcance / Sense of coherence in breastfeeding women: A scoping review

Fundamento. El establecimiento de la lactancia materna puede resultar una situación potencialmente estresante. El objetivo del estudio es analizar el sentido de coherencia en mujeres lactantes, establecer los recursos generales de resistencia que lo modulan, y determinar las intervenciones profesionales que lo promueven. Metodología. Se incluyeron estudios en inglés, español o portugués, que evaluaran el sentido de coherencia de las mujeres lactantes, localizados en las bases de datos PubMed, PsycINFO, ScienceDirect y CINAHL entre marzo y mayo de 2023. La calidad de los estudios y el riesgo de sesgo se evaluaron siguiendo los criterios ICROMS y STROBE. Resultados. Se identificaron 316 registros, de los que se incluyeron un total de ocho estudios, tres cualitativos y cinco cuantitativos, todos con calidad suficiente. Un alto nivel de sentido de coherencia materno se relacionó con mayor duración, autoeficacia y disfrute de la experiencia de lactancia, y mayor apego. Los principales recursos generales de resistencia fueron percibir apoyo social, especialmente de parejas, madres y personal sanitario, además de experiencia previa positiva y una actitud positiva. Las intervenciones que favorecieron el sentido de coherencia fueron las relacionadas con un apoyo profesional estrecho, empático, personalizado, integral y centrado en la familia. Conclusiones. La determinación del nivel de sentido de coherencia en madres lactantes puede ayudar a identificar a mujeres con mayor riesgo de destete temprano, y a establecer estrategias de intervención profesional que mejoren la experiencia de lactancia materna.

Violencia obstétrica como factor de riesgo de adopción del rol maternal: una revisión bajo la teoría de Mercer / Obstetric violence as a risk factor for adoption of the maternal role: a review under Mercer's theory

Objetivo: Explorar la influencia de la exposición a violencia obstétrica en la adopción del rol materno bajo la teoría de Ramona Mercer. Metodología: Revisión bibliográfica. Se llevaron a cabo búsquedas en las bases de datos MEDLINE/PubMed, PsycINFO, BVS/LILACS, ScienceDirect, WOS y Scielo entre enero y julio de 2023. Se incluyeron estudios en inglés y español; publicados en los últimos diez años, y que estudiaran la relación entre violencia obstétrica y la adopción del rol materno. Resultados: Se incluyeron un total de 14 estudios. Se evidenció que los procedimientos relacionados con violencia obstétrica se asocian con una interrupción del vínculo madre-bebé; mayor dificultad e inseguridad para la instauración del cuidado materno; menor establecimiento de la lactancia materna precoz; trastorno de estrés postraumático y depresión posparto. Estos hallazgos se ajustan a la teoría de adopción del rol materno de Mercer. Conclusiones: El sufrimiento de violencia obstétrica supone un factor de riesgo para la instauración del rol materno, repercutiendo en el binomio madre-bebé. El hecho de facilitar una experiencia de parto positiva podría mejorar dicho proceso y se traduciría en una inversión que contribuiría al bienestar del desarrollo infantil. (AU)

Objective: Explore the influence of exposure to obstetric violence on the adoption of the maternal role under Ramona Mercer's theory. Methodology: Literature review. Searches were carried out in the MEDLINE/PubMed, PsycINFO, BVS/LILACS, ScienceDirect, WOS and Scielo databases between January and July 2023. Studies were included in English, Spanish; published in the last ten years; to study the relationship between obstetric violence and the adoption of the maternal role. Results: A total of 14 studies were included. It was evidenced that procedures related to obstetric violence are associated with an interruption of the mother-baby bond; greater difficulty and insecurity in establishing maternal care; less establishment of early breastfeeding; post-traumatic stress disorder and postpartum depression. These findings fit Mercer's Maternal Role Adoption Theory. Conclusions: Suffering from obstetric violence is a risk factor for the establishment of the maternal role, impacting the mother-baby binomial. Facilitating a positive birth experience could improve this process and would translate into an investment that would contribute to the well-being of child development. (AU)

Comparison between Colistin and Polymyxin B in the Treatment of Bloodstream Infections Caused by Carbapenem-Resistant Pseudomonas aeruginosa and Acinetobacter baumannii-calcoaceticus Complex.

Polymyxins are still widely used for the treatment of carbapenem-resistant Acinetobacter baumannii and Pseudomonas aeruginosa bloodstream infections (BSIs). This study seeks to evaluate the impact of polymyxin B versus colistin on mortality and nephrotoxicity in BSI caused by these bacteria. We conducted a retrospective cohort study from 2014 to 2021 in Porto Alegre, Brazil. We included patients aged ≥18 years and excluded patients with polymicrobial infection or treatment for ≤48 h. The 30-day mortality was the primary outcome evaluated through Cox regression. We included 259 patients with BSI episodes: 78.8% caused by A. baumannii and 21.2% caused by P. aeruginosa. Polymyxin B did not impact mortality compared to colistin (adjusted hazard ratio (aHR), 0.82; 95% confidence interval (CI), 0.52-1.30; p = 0.40 (when adjusted for COVID-19 comorbidity, p = 0.05), Pitt bacteremia score, p < 0.01; Charlson comorbidity index, p < 0.001; time to start active antimicrobial therapy, p = 0.02). Results were maintained in the subgroups of BSI caused by A. baumannii (aHR, 0.92; 95% CI, 0.55-1.54; p = 0.74), P. aeruginosa (aHR, 0.47; 95% CI, 0.17-1.32; p = 0.15) and critical care patients (aHR, 0.77; 95% CI, 0.47-1.26; p = 0.30). Treatment with polymyxin B or colistin did not impact 30-day mortality in patients with carbapenem-resistant A. baumannii or P. aeruginosa BSI.

Effect of pelvic floor muscle training on female sexual function: A systematic review protocol and meta-analysis.

AIM: To recognize, appraise and summarize the research evidence that has explored the results of pelvic floor muscle training on female sexual function. DESIGN: Systematic review and possible meta-analysis. METHODOLOGY: Between September and October 2022, the Cochrane Library, CINAHL, MEDLINE, EMBASE, PsycINFO and Scopus electronic databases will be searched. We will include RCT's in English, Spanish and Portuguese that investigate the results of pelvic floor muscle training on female sexual function. The data will be extracted by two researchers independently. Risk of bias will be measured from the Cochrane Risk of Bias Tool. The meta-analysis of the results will be performed using Comprehensive Meta-Analysis Version 2. RESULTS: This systematic review and possible meta-analysis will contribute significantly to the promotion of pelvic floor health and women's sexual function and to strengthen clinical practice and define other areas of study.

Human footprint on the water quality from the northern Antarctic Peninsula region.

This study assessed the human footprint on the chemical pollution of Antarctic waters by characterizing inorganic chemicals and selected organic anthropogenic contaminants of emerging concern (CECs) in inland freshwater and coastal seawater and the associated ecotoxicological risk. Nicotine and tolytriazole, present in 74% and 89% of the samples analyzed, respectively, were the most ubiquitous CECs in the investigated area. The most abundant CECs were citalopram, clarithromycin, and nicotine with concentrations reaching 292, 173, and 146 ng/L, respectively. The spatial distribution of CECs was not linked to any water characteristic or inorganic component. The contamination pattern by CECs in inland freshwater varied among locations, whereas it was very similar in coastal seawater. This suggests that concentrations in inland freshwater may be ruled by environmental processes (reemission from ice, atmospheric deposition, limited photo- and biodegradation processes, etc.) in addition to human activities. Following risk assessment, citalopram, clarithromycin, nicotine, venlafaxine, and hydrochlorothiazide should be considered of concern in this area, and hence, included in future monitoring of Antarctic waters and biota. This work provides evidence on the fact that current measures taken to protect the pristine environment of Antarctica from human activities are not effective to avoid CEC spread in its aquatic environment.

The Impact of COVID-19 Lockdown on Adults with Major Depressive Disorder from Catalonia: A Decentralized Longitudinal Study.

The present study analyzes the effects of each containment phase of the first COVID-19 wave on depression levels in a cohort of 121 adults with a history of major depressive disorder (MDD) from Catalonia recruited from 1 November 2019, to 16 October 2020. This analysis is part of the Remote Assessment of Disease and Relapse-MDD (RADAR-MDD) study. Depression was evaluated with the Patient Health Questionnaire-8 (PHQ-8), and anxiety was evaluated with the Generalized Anxiety Disorder-7 (GAD-7). Depression's levels were explored across the phases (pre-lockdown, lockdown, and four post-lockdown phases) according to the restrictions of Spanish/Catalan governments. Then, a mixed model was fitted to estimate how depression varied over the phases. A significant rise in depression severity was found during the lockdown and phase 0 (early post-lockdown), compared with the pre-lockdown. Those with low pre-lockdown depression experienced an increase in depression severity during the "new normality", while those with high pre-lockdown depression decreased compared with the pre-lockdown. These findings suggest that COVID-19 restrictions affected the depression level depending on their pre-lockdown depression severity. Individuals with low levels of depression are more reactive to external stimuli than those with more severe depression, so the lockdown may have worse detrimental effects on them.

Antimicrobial Therapy Duration for Bloodstream Infections Caused by Pseudomonas aeruginosa or Acinetobacter baumannii-calcoaceticus complex: A Retrospective Cohort Study.

BACKGROUND: Ideal therapy duration for Pseudomonas aeruginosa or Acinetobacter baumannii-calcoaceticus complex (ABC) bloodstream infections (BSI) is not defined, especially in the context of carbapenem resistance. In this study, we compared short- (≤7 days) and long-term (>7 days) antimicrobial therapy duration for these infections. METHODS: We performed a retrospective cohort study in two tertiary-care hospitals in Porto Alegre, Brazil, from 2013 to 2019. Eligible patients aged ≥18 years were included and excluded for the following criteria: polymicrobial infections, treatment with non-susceptible antibiotics, complicated infections, or early mortality (<8 days of active antimicrobial therapy). The 30-day mortality risk was evaluated using a Cox regression model. RESULTS: We included 237 BSI episodes, 51.5% caused by ABC and 48.5% by Pseudomonas aeruginosa. Short-term therapy was not associated with 30-day mortality, adjusted hazard ratio 1.01, 95% confidence interval 0.47-2.20, p = 0.98, when adjusted for Pitt score (p = 0.02), Charlson Comorbidity Index score (p < 0.01), and carbapenem resistance (p < 0.01). Among patients who survived, short-term therapy was associated with shorter hospital stay (p < 0.01). Results were maintained in the subgroups of BSI caused by carbapenem-resistant bacteria (p = 0.76), ABC (p = 0.61), and Pseudomonas aeruginosa (p = 0.39). CONCLUSIONS: Long-term therapies for non-complicated Pseudomonas aeruginosa and ABC BSI were not superior to short-term therapy for 30-day mortality.

Best Practices from Eight European Dementia-Friendly Study Cases of Innovation.

The concept of dementia-friendly cities and communities has achieved great dissemination in the international context since 2016. Although it is usually related with community networks and services, evidence and guidelines show the close relationship between the built environment design, health promotion, and the preservation of relationships with the local surroundings. Recent publications emphasize best practices in urban areas and care management. However, this is a very complex reality in each country depending on the sociosanitary services, the demographic, and geographic structure and many other different aspects including cultural ones. Moreover, design should also consider not only basic aspects such as habitability or universal accessibility, but also heritage, identity, and the feeling of normalized living. Knowledge about international experiences and innovative approaches is, as yet, an object of study as demographic ageing is still challenging all the welfare systems, especially in Europe. This study presents eight descriptive study cases in three different European countries-the United Kingdom, Belgium, and The Netherlands-to analyze the relationship between dementia-friendly initiatives and their intersection with design, urban planning and the provision of care. The results can provide strategic lines for development and innovation towards dementia-friendly societies and cities achieving SDG numbers 3 and 11 simultaneously.

Antibiotics in the Basque coast (N Spain): Occurrence in waste and receiving waters, and risk assessment (2017-2020).

The study of the presence of antibiotics in the aquatic environment is a preliminary step to analyse their possible harmful effects on aquatic ecosystems. In order to monitor their occurrence in the aquatic environment, the European Commission established in 2015, 2018, and 2020 three Watch Lists of substances for Union-wide monitoring (Decisions (EU) 2015/495, 2018/840, and 2020/1161), where some antibiotics within the classes of macrolides, fluoroquinolones and penicillins were included. In the Basque coast, northern Spain, three macrolide antibiotics (erythromycin, clarithromycin, azithromycin) and ciprofloxacin were monitored quarterly from 2017 to 2020 (covering a period before and after the COVID19 outbreak), in water samples collected from two Waste Water Treatment Plants (WWTPs), and three control points associated with receiving waters (transitional and coastal water bodies). This work was undertaken for the Basque Water Agency (URA). The three macrolide antibiotics in water showed a frequency of quantification >65 % in the Basque coast, with higher concentrations in the WWTP emission stations than in receiving waters. Their frequency of quantification decreased from 2017 to 2020, as did the consumption of antibiotics in Spanish primary care since 2015. Ciprofloxacin showed higher frequencies of quantification in receiving waters than in wastewaters, but the highest concentrations were observed in the WWTP emission stations. Although consumption of fluoroquinolones (among which is ciprofloxacin) in primary care in the Basque Country has decreased in recent years, this trend was not observed in the waters sampled in the present study. On the other hand, concentrations of clarithromycin, azithromycin, and ciprofloxacin in receiving waters exceeded their respective Predicted No-Effect Concentrations, so they could pose an environmental risk. These substances are widely used in human and animal medicine, so, although only ciprofloxacin is included in the third Watch List, it would be advisable to continue monitoring macrolides in the Basque coast as well.

Modulating Elements of Nurse Resilience in Population Care during the COVID-19 Pandemic.

COVID-19 has significantly affected the work environment of nurses. In the face of the challenges posed by stressors in clinical practice, some nurses adapt and prove to be resilient. In the face of the COVID-19 pandemic, the nature of care itself and the new ways of working are potentially very stressful. We aim to analyze the resilience of care nurses to the psychological impact of the COVID-19 pandemic. This study is a systematic review of nurse caregiver resilience to the COVID-19 pandemic in 2021. Our search was conducted in the WOS, Medline/PubMed, Cochrane, BVS/LILACS, and Cuiden databases. The inclusion criteria were: studies published in Spanish or English; carried out from March 2020 to May 2021 on nurses caring for patients with COVID-19; and investigating the factors influencing the psychological impact, resilience, strategies to develop it, and interventions to promote it during this pandemic and others, such as SARS, MERS, or ebola. The quality of the studies and the risk of bias were evaluated following ICROMS, STROBE and AMSTAR-2 criteria. Twenty-two studies were selected. Most of the studies highlighted the presence of stressors in nurses, emphasizing those of the environment, which converged in dysfunctional responses that hurt their resilience. The most persuasive factors were social and organizational support. Coping strategies developed by nurses and especially interventions by organizations were detected as instruments to foster resilience, but have not been well researched. Resilience has a key moderating role in mitigating the psychological impact of nurses in the face of the COVID-19 pandemic.

Thromboembolism and Oral Contraceptives During the COVID-19 Pandemic: A Disproportionality Analysis Within the Spanish Pharmacovigilance Database.

BACKGROUND: Thromboembolic events (TEs) are known to be a severe complication for COVID-19. They are associated with a systemic inflammatory response syndrome with coagulation cascade activation. OBJECTIVE: The aim of this study was to determine a potential association between the COVID-19 pandemic and the increment of the risk of suspected TEs in women on systemic hormonal contraceptives (SHCs). PATIENTS AND METHODS: This study utilised a case/non-case approach in the Spanish Pharmacovigilance Database, which includes more than 290,000 cases of suspected adverse drug reactions (ADRs). The reporting odds ratio (ROR) was calculated during an initial pandemic period in 2020 compared with a pre-pandemic period in 2019 and an additional control period in 2018. RESULTS: While there was a decreased number of ADR notifications for any medications and for any type of ADR in patients on SHCs during the pandemic period, the TE ROR for all SHCs was higher in the 2020 pandemic period [ROR = 11.8 (5.6-24.7)] relative to the pre-pandemic period in 2019 [ROR = 6.3 (3.2-12.5)] and the additional control period in 2018 [ROR = 4.6. (2.1-9.9)]. In contrast, ROR for progestogen-only contraceptives was lower during the pandemic as compared with the two control periods. CONCLUSION: The reported disproportionality of TEs in women on SHCs rose during the pandemic period. This suggests a potential interaction of the drug (SHC) with COVID-19, which led to an increased risk of TEs in women exposed to both factors. This should be taken into consideration in the context of the COVID-19 pandemic.

Fungal degradation of selected medium to highly polar pesticides by Trametes versicolor: kinetics, biodegradation pathways, and ecotoxicity of treated waters.

The massive use of pesticides represents one of the main causes of environmental deterioration, as they have adverse effects on non-target organisms. Thus, the development of technologies capable of reducing their release into the environment is urgently needed. This study reports for the first time the white-rot fungus Trametes versicolor as an alternative towards the degradation of medium to highly polar pesticides such as the organophosphate malathion, and the neonicotinoids acetamiprid and imidacloprid. Specifically, T. versicolor could completely remove 1 mg/L of malathion in an Erlenmeyer flask within 48 h, while experiments of acetamiprid and imidacloprid (4 mg/L), conducted in air-pulse fluidized bioreactors, resulted in degradation percentages of 20% and 64.7%, respectively, after 7 days of operation. Enzymatic exploration studies revealed that the cytochrome P450 system, instead of the extracellular enzyme laccase, is involved in the degradation of acetamiprid and imidacloprid. The degradation pathways were proposed based on the main transformation products (TPs) formed in the solutions: seven in the case of malathion, and two and one in the case of imidacloprid and acetamiprid, respectively. Although the TPs identified were predicted to be less toxic than the investigated pesticides, the toxicity of the individual solutions slightly increased throughout the degradation process, according to the Microtox assay. However, the solution toxicity was always below the threshold established in the local regulation. Although additional research is needed to implement this treatment at a pilot plant scale, this work highlights the potential of T. versicolor to bio-remediate pesticide-contaminated waters.

Evaluation of an outdoor pilot-scale tubular photobioreactor for removal of selected pesticides from water.

This work assesses the capacity of a microalgae-based system to remove three highly to medium polar pesticides typically found in freshwater: acetamiprid, bentazone, and propanil. Degradation of the pesticides was firstly studied individually at batch lab-scale reactors and abiotic and heated-killed controls were employed to clarify their removal pathways. At lab-scale, propanil and acetamiprid were completely removed after 7 days whereas bentazone was not removed. Four and two transformation products (TPs) were generated in the biodegradation process for acetamiprid and propanil, respectively. Then, the simultaneous removal of the pesticides was assessed in an outdoor pilot photobioreactor, operated with a hydraulic residence time of 8 days. During the steady-state, high removal efficiencies were observed for propanil (99%) and acetamiprid (71%). The results from batch experiments suggest that removal is mainly caused by algal-mediated biodegradation. Acetamiprid TPs raised throughout the operational time in the photobioreactor, while no propanil TP was detected at the pilot-scale. This suggests complete mineralization of propanil or residual formation of its TPs at concentrations below the analytical method detection limit. Aiming at biomass valorization, diverse microalgae harvesting methods were investigated for biomass concentration, and the effect of residual pesticides on the biogas yield was determined by biochemical methane potential tests. Anaerobic digestion was not inhibited by the pesticides as verified by the digestion performance. The results highlight the potential of microalgae-based systems to couple nutrient removal, biomass production, micropollutant biodegradation, and biofuel production.

Notificación de sospechas de reacciones adversas a medicamentos por enfermeras en España. Un estudio observacional descriptivo retrospectivo / Reporting of suspected adverse drug reactions by nursing in Spain. An observational-descriptive retrospective study

Objetivo: Conocer el grado de participación de las enfermeras en la notificación espontánea de sospechas de reacciones adversas a medicamentos (RAM) al Sistema Español de Farmacovigilancia de Medicamentos de Uso Humano (SEFV-H), describir las características principales de los casos notificados e identificar puntos de mejora. Método: Estudio observacional descriptivo retrospectivo a partir de la información contenida en la base de datos FEDRA del SEFV-H. Se tomaron como muestra las notificaciones espontáneas de las RAM realizadas por enfermeras durante los seis primeros meses del 2018. Resultados: De las 6.370 sospechas de RAM notificadas por profesionales sanitarios en el periodo considerado, tan solo un 4,8% fueron realizadas por enfermeras. El 62,7% procede de centros extrahospitalarios y la mayoría de las RAM son consideradas no graves (78%). Las reacciones notificadas con más frecuencia son las reacciones locales. Los pacientes más implicados son los niños y las vacunas los medicamentos más notificados (58,3%), seguidas de los contrastes intravenosos para la realización de pruebas diagnósticas. Conclusiones: Las enfermeras notifican muy pocos casos al SEFV-H y están en su mayoría relacionados con la administración de vacunas y son enviados por enfermeras que trabajan en el medio extrahospitalario. La mayoría de los casos no presentan gravedad y suelen referir reacciones adversas conocidas para el fármaco sospechoso. Esta infranotificación observada plantea la necesidad de promover la formación en materia de farmacovigilancia entre estas enfermeras notificadoras para que continúen notificando, y también a las que no lo hacen en su práctica diaria, para que puedan comenzar a hacerlo.(AU)

Objective: This study aimed to gain knowledge of the nurses’ involvement in the spontaneous report of suspected adverse drug reactions (ADR) in the Spanish Pharmacovigilance System for Medicinal Products for Human Use (SEFV-H), describing the principal characteristics of the reported cases, identifying points of improvement. Methods: A descriptive observational retrospective study was based on the data from FEDRA, the database created by the SEFV-H. The sample taken was the spontaneous adverse drug reactions reported to SEFV-H by nurses during the first 6 months of the 2018. Results: Complete data was provided by 6,370 suspicions of ADR reported to SEFV-H by all healthcare professionals. Only 4,8% of the samples were taken by nurses, 62,7% came from medical centers. The majority of the ADR were not considered a serious disease (78%). The most frequently adverse drug reactions reported by nurses were local reactions. The patients most involved were children and vaccines were the most reported drugs (58,3%), followed by the intravenous contrast agents used in diagnostic tests. Conclusions: Nurses report very few cases to SEFV-H and are mostly related to the administration of vaccines and are sent by nurses working in the out-of-hospital setting. Most cases are not serious and usually report known adverse reactions to the suspected drug. This observed under-notification raises the need to promote increased pharmacovigilance training among these notifying nurses so that they can continue to report, and also for those who do not do so in their daily practice, so that they can begin to do so.(AU)

Obesity and Gray Matter Volume Assessed by Neuroimaging: A Systematic Review.

Obesity has become a major public and individual health problem due to its high worldwide prevalence and its relation with comorbid conditions. According to previous studies, obesity is related to an increased risk of cognitive impairment and dementia. This systematic review aims to further examine the present state of the art about the association between obesity and gray matter volume (GMV) as assessed by magnetic resonance imaging (MRI). A search was conducted in Pubmed, SCOPUS and Cochrane of those studies released before 1 February 2021 including MRIs to assess the GMVs in obese participants. From this search, 1420 results were obtained, and 34 publications were finally included. Obesity was mainly measured by the body mass index, although other common types of evaluations were used (e.g., waist circumference, waist-to-hip ratio and plasma leptin levels). The selected neuroimaging analysis methods were voxel-based morphometry (VBM) and cortical thickness (CT), finding 21 and 13 publications, respectively. There were 30 cross-sectional and 2 prospective longitudinal studies, and 2 articles had both cross-sectional and longitudinal designs. Most studies showed a negative association between obesity and GMV. This would have important public health implications, as obesity prevention could avoid a potential risk of GMV reductions, cognitive impairment and dementia.

Effect of processing smoked salmon on contaminant contents.

The influence of the type of smoking process (natural/liquid; hot/cold) and salt (NaCl or KCl) on the levels of polybrominated diphenyl ethers (PBDEs) and polycyclic aromatic hydrocarbons (PAHs) in smoked salmon was evaluated. One parent compound - BDE 47 - and two methoxylated forms - 2'-MeO-BDE-68 and 6-MeO-BDE-47 - were detected in all the samples. Among the 14 PAHs analysed, naphthalene was the most abundant followed by phenanthrene and fluorene. Only smoked salmon treated with NaCl presented quantifiable levels of chrysene and benzo[b]fluoranthene. Among the four smoking processes evaluated, natural smoke led to higher levels of PAHs. Risk characterization tools, such as hazard index (HI) and incremental lifetime cancer risk (ILCR), showed that the risk of both PBDEs and PAHs to human health through the consumption of smoked salmon was very low.
