Abstract
The impact of airport activities on air quality, is not sufficiently documented. In order to better understand the magnitude and properly assess the sources of emissions in the sector, it is necessary to establish databases with real data on those pollutants that could have the greatest impact on both health and the environment. Particulate matter (PM), especially ultrafine particles, are a research priority, not only because of its physical properties, but also because of its ability to bind highly toxic compounds such as polycyclic aromatic hydrocarbons (PAHs). Samples of PM were collected in the ambient air around the runways at Barajas International Airport (Madrid, Spain) during October, November and December 2021. Samples were gathered using three different sampling systems and analysed to determine the concentration of PAHs bound to PM. A high-volume air sampler, a Berner low-pressure impactor, and an automated off-line sampler developed in-house were used. The agreement between the samplers was statistically verified from the PM and PAH results. The highest concentration of PM measured was 31 μg m-3, while the concentration of total PAH was 3 ng m-3, both comparable to those recorded in a semi-urban area of Madrid. The PAHs showed a similar profile to the particle size distribution, with a maximum in the 0.27-0.54 μm size range, being preferentially found in the submicron size fractions, with more than 84% and around 15-20% associated to UFPs. It was found that the ratio [PAHs(m)/PM(m)] was around 10-4 in the warmer period (October), whereas it more than doubled in the colder months (November-December). It is significant the shift in the relative distribution of compounds within these two periods, with a notable increase in the 5 and 6 ring proportions in the colder period. This increase was probably due to the additional contribution of other external sources, possibly thermal and related to combustion processes, as supported by the PAH diagnostic ratios.

Abstract
This article explores HIV awareness and prevention in a Latinx seasonal farmworker community of south Miami-Dade County in the USA. The study took place as part of a larger community assessment that aimed to determine community needs and resources related to substance abuse, violence and HIV in the Latinx seasonal farmworker communities of south Miami-Dade County, with a particular focus on fathers' and their male sons' relationships. The study collected data on HIV knowledge and prevention, healthcare-seeking behaviours, cultural norms, and communication barriers about HIV prevention between fathers and sons. Data were collected through in-depth interviews with community leaders, two focus groups with social and health services providers, and four focus groups involving fathers and their adolescent sons. A deductive approach to data analysis was undertaken. Five major themes were identified: (1) HIVrelated knowledge and perception; (2) HIV prevention strategies; (3) barriers and needs for tailored preventive health and care services in the community; (4) stress over sex-related communication; and (5) the dominance of traditional masculine gender norms in the household and the community.

Abstract
Objective.To present an innovative approach for the design of a 3D mammographic phantom for medical equipment quality assessment, estimation of the glandular tissue percentage in the patient's breast, and emulation of microcalcification (μC) breast lesions.Approach.Contrast-to noise ratio (CNR) measurements, as well as spatial resolution and intensity-to-glandularity calibrations under mammography conditions were performed to assess the effectiveness of the phantom. CNR measurements were applied to different groups of calcium hydroxyapatite (HA) and aluminum oxide (AO)μCs ranging from 200 to 600μm. Spatial resolution was characterized using an aluminum plate contained in the phantom and standard linear figures of merit, such as the line spread function and modulation transfer function (MTF). The intensity-to-glandularity calibration was developed using an x-ray attenuation matrix within the phantom to estimate the glandular tissue percentage in a breast with a compressed thickness of 4 cm.Main results.For the prototype studied, the minimum confidence level for detecting HAμCs is 95.4%, while for AOμCs is above 68.3%. It was also possible to determine that the MTF of the commercial mammography machine used for this study at the Nyquist frequency is 41%. Additionally, a one-to-one intensity-to-glandularity calibration was obtained and verified with Monte-Carlo simulation results.Significance.The phantom provides traditional arrangements presented in accreditation phantoms, which makes it competitive with available devices, but excelling in regarding affordability, modularity, and inlays distribution. Moreover, its design allows to be positioned in close proximity to the patient's breast during a medical screening for a simultaneous x-ray imaging, such that the features of the phantom can be used as reference values to specify characteristics of the real breast tissue, such as proportion of glandular/adipose composition and/orμC type and size lesions.

Abstract
In the Mediterranean basin, the tick species Hyalomma lusitanicum Koch stands out among other species of the Hyalomma genus due to its wide distribution, and there is great concern about its potential role as a vector and/or reservoir and its continuous expansion to new areas because of climate warming and human and other animal movements. This review aims to consolidate all the information on H. lusitanicum, including taxonomy and evolution, morphological and molecular identification, life cycle, sampling methods, rearing under laboratory conditions, ecology, hosts, geographical distribution, seasonality, vector role and control methods. The availability of adequate data is extremely relevant to the development of appropriate control strategies in areas where this tick is currently distributed as well as in new areas where it could become established in the near future.

Abstract
Little is known about the long-term effects of maternal diabetes during pregnancy (DP), either gestational diabetes or preexisting diabetes (type 1 or type 2), on offspring's brain morphometry and neurocognitive functioning (NCF). This study examined the effect of prenatal exposure to maternal DP on the brain structure and NCF in children between 9 and 10 years of age. This study used cross-sectional neuroimaging and NCF data from the baseline wave of the Adolescent Brain and Cognitive Development® study. Exposure to maternal DP was assigned from the developmental history questionnaire. Differences in the brain cortical thickness (CTh) and five cognitive abilities (executive function, working and episodic memory, processing speed, and language abilities) were examined in diabetes-exposed and diabetes-unexposed children. Linear mixed effect models and generalized linear models were used to adjust for the effect of confounding variables. A total of 9,967 children (718 diabetes-exposed and 9249 unexposed) were included in the analysis. Diabetes-exposed children had lower whole-brain CTh [mean: exposed vs unexposed = 2.725 mm vs 2.732 mm; difference (95%CI): -0.007 mm (-0.013, -0.001)] compared to unexposed children after adjusting for confounding variables. Diabetes-exposed children had lower CTh in most part of the occipital lobe of both hemispheres, right postcentral gyrus, and left superior parietal cortex. Diabetes-exposed children also had lower scores in processing speed task [mean difference (95%CI): -1.7 (-2.8, -0.6)] and total cognition [mean difference (95%CI): -0.6 (-1.2, -0.02)]. Diabetes-exposed children have reduced CTh and NCF during preadolescence, which might have implications for psychomotor development during later life. Prospective studies are needed to confirm our findings.

Abstract
Magnetic resonance has become a first-line imaging modality in various clinical scenarios. The number of patients with different cardiovascular devices, including cardiac implantable electronic devices, has increased exponentially. Although there have been reports of risks associated with exposure to magnetic resonance in these patients, the clinical evidence now supports the safety of performing these studies under specific conditions and following recommendations to minimize possible risks. This document was written by the Working Group on Cardiac Magnetic Resonance Imaging and Cardiac Computed Tomography of the Spanish Society of Cardiology (SEC-GT CRMTC), the Heart Rhythm Association of the Spanish Society of Cardiology (SEC-Heart Rhythm Association), the Spanish Society of Medical Radiology (SERAM), and the Spanish Society of Cardiothoracic Imaging (SEICAT). The document reviews the clinical evidence available in this field and establishes a series of recommendations so that patients with cardiovascular devices can safely access this diagnostic tool.

Abstract
PURPOSE To compare the detection of human cytomegalovirus (HCMV) in bronchoalveolar lavage (BAL) fluid by viral culture and quantitative polymerase chain reaction (qPCR), and to establish a viral load threshold that can identify cases of HCMV replication indicative of pneumonitis. There is currently no universal viral load cut-off to differentiate between patients with and without pneumonitis, and the interpretation of qPCR results is challenging. METHODS 176 consecutive BAL samples from immunosuppressed hosts with signs and/or symptoms of respiratory infection were prospectively studied by viral culture and qPCR. RESULTS Concordant results were obtained in 81.25% of the BAL samples. The rest were discordant, as only 34% of the qPCR-positive BAL samples were positive by culture. The median HCMV load was significantly higher in culture-positive than in culture-negative BAL samples (5,038 vs 178 IU/mL). Using a cut-off value of 1,258 IU/mL of HCMV in BAL, pneumonia was diagnosed with a sensitivity of 76%, a specificity of 100%, a VPP of 100% and VPN of 98%, and HCMV was isolated in 100% of the BAL cultures. CONCLUSION We found that a qPCR-negative was a quick and reliable way of ruling out HCMV pneumonitis, but a positive result did not always indicate clinically significant replication in the lung. However, an HCMV load in BAL fluid of ≥1,258 IU/mL was always associated with disease, whereas <200 IU/mL rarely so.

The aim of the study was to examine the association between prenatal exposure to maternal Hypertensive disorder during pregnancy (HDP) on brain structure and neurocognitive functioning (NCF) in singleton children aged between 9 and 10 years using the baseline wave of the Adolescent Brain and Cognitive Development (ABCD) Study. The ABCD Study® interviewed each child (and their parents), measured NCF, and performed neuroimaging. Exposure to maternal high blood pressure (HBP) and preeclampsia or eclampsia (PE/EL) were extracted from the developmental history questionnaire. Differences in cortical thickness (CTh) and five cognitive abilities (two executive functions, working and episodic memory, processing speed, and two language abilities) between exposed and unexposed children were examined using generalized linear models. The mediating effects of CTh, birthweight, and BMI on the relationship between maternal HDP on NCF were also examined. A total of 584-children exposed to HBP, 387-children exposed to PE/EL, and 5,877 unexposed children were included in the analysis. Neither CTh nor NCF differed between the exposed and unexposed children with or without adjusting for the confounders including the child's age, sex, race, education, and birth histories. The whole-brain CTh did not mediate the relationships between HDP and NCF. However, the relationship between HDP and most of the NCF was mediated by the child's birthweight and BMI. Exposure to maternal HDP can affect their offspring's later-life cognitive abilities via low birthweight and BMI during childhood. Prospective longitudinal studies, following up from infancy, are needed to further delineate the association of HDP on children's cognitive abilities.

Abstract
Longevity is an economically important trait, since extending the functional life of a doe would allow us to keep the most productive females in the herd as long as possible, and this could result in the increased profitability of dairy farms. Thus, the objectives of this study were to determine the most important factors that influence the length of productive life (LPL) of female Florida goats and to estimate its genetic additive variance using a Cox proportional hazards model. The data consisted of 70,695 productive life records from 25,722 Florida females kidding between 2006 and 2020. A total of 19,495 does had completed their productive life while 6227 (24.2%) does had censored information. The pedigree contained information on 56,901 animals. The average censoring age and average failure age after first kidding for LPL were 36 and 47 months respectively. The model included, as time-independent effects, the age at first kidding and the interaction between herd, year and season of birth of the doe, and as time-dependent effects, the age at kidding, the interaction between herd, year and season of kidding, the within-herd class of milk production deviation, and the interaction between the lactation number and the stage of lactation. All fixed effects had a significant effect on LPL (p < 0.05). Does with older ages at the first kidding and an earlier age at kidding were at higher risk of being culled. A large difference among herds was observed in terms of culling risk, which highlighted the importance of adequate management practices. Also, high-producing does were less likely to be culled. The estimate of the additive genetic variance was 1.844 (in genetic standard deviation), with a heritability estimate of 0.58 ± 0.012. The results of this study are expected to contribute to the development of a genetic model for genetic evaluation of the length of the productive life of Spanish dairy goat breeds.

Abstract
INTRODUCTION Emerging adulthood is a distinct and challenging developmental stage of life. It may be particularly stressful for Hispanic emerging adults due to various cultural stressors. However, there is little research on the impact of one particular cultural stressor, the acculturation gap. Therefore, this study aims to examine whether acculturation gap conflicts are associated with self-rated health. METHOD Participants were recruited in Arizona and Florida, and 200 Hispanic emerging adults (ages 18-25) completed a cross-sectional survey. Data were analyzed using hierarchical multiple regression. RESULTS Coefficients from a hierarchical multiple regression model indicated that higher levels of acculturation gap conflicts were associated with lower self-rated health after controlling for psychological stress and other demographic variables. DISCUSSION This is the first study on acculturation gap conflicts and self-rated health among Hispanics. Findings from this study indicate that acculturation gap conflicts are associated with self-rated health and merit further investigation as they may have implications for health interventions targeting Hispanics.

Abstract
BACKGROUND Although Latino immigrants to the United States tend to display a gradual increase in alcohol use after immigration, such escalation may not generalize to all Latino/a groups. This study examines patterns of alcohol use shown by recent Latino immigrants (RLIs) to Miami/Dade County (MDC), Florida covering a period from pre-immigration to the first two years after immigration. Differences in alcohol use prior to and during the COVID-19 pandemic were also assessed. METHODS Data came from an on-going longitudinal study of 540 young adult (50% female) RLIs. Inclusion criteria were age 18 to 34, residing in MDC and having immigrated from a Latin American country within the past year. Respondent-driven sampling was the primary recruitment strategy. RESULTS Recent Latino immigrants reported a decline in alcohol use from before immigration (18.3 drinks per month, d/m) to the first (13.9 d/m), and second years (10.4 d/m before and 12.9 d/m during the pandemic lockdown) in MDC. The decline, which was moderated by RLIs' sex and legal residency status, was halted by the pandemic lockdown. While "to celebrate" was the most often cited reason for drinking, "to forget" was often cited during the lockdown. CONCLUSIONS The noted decrease in alcohol use since immigration may reflect the unique array of support and resources available to RLIs in MDC. Nevertheless, some RLIs increased their alcohol use over time, particularly during the COVID-19 pandemic. This disparate impact of the pandemic on alcohol use calls attention to the need to identify the most vulnerable RLIs to MDC and develop targeted interventions for them.

Abstract
El objetivo fue analizar el efecto de diferentes tipos de feedback sobre variables psicológicas y de rendimiento en función de la percepción del deportista de la competencia del entrenador. Se realizó un estudio de caso con 33 futbolistas asignados aleatoriamente a tres condiciones experimentales (feedback positivo, negativo y ausencia de feedback). Se midieron velocidad y precisión de lanzamientos a portería, valoración de competencia, competencia percibida, motivación autónoma y vitalidad subjetiva. Se empleó un nivel ? de 0,05 para los análisis. El grupo feedback positivo exhibió niveles más altos de valoración de competencia, competencia percibida, motivación autónoma y bienestar, que los de feedback negativo y ausencia de feedback, en sujetos con alta percepción de competencia del entrenador. Este efecto no se observó en aquellos con baja percepción de competencia del entrenador. La percepción del jugador sobre la competencia del entrenador podría ser un factor en la modulación de las diferencias generadas en cuanto al tipo de feedback.

Abstract
The removal of emerging pollutants from municipal wastewater was studied for the first time using a three-step pilot-scale system: 1) hybrid digester (HD) as first step, 2) subsurface vertical flow constructed wetland (VF) as second step, and 3) photodegradation (PD) unit as third step or post-treatment. The HD and VF units were built and operated in series with effluent recirculation at pilot scale. For the PD post-treatment, three alternatives were studied at lab-scale, i) UVC irradiation at 254 nm (0.5 h exposure time), ii) UVA irradiation at 365 nm using a TiO2-based photocatalyst and iii) sunlight irradiation using a TiO2-based photocatalyst, the last two for 1 and 2 h. Alternative iii) was also tested at pilot-scale. Degradation of nine compounds was evaluated: acetaminophen (ACE), caffeine (CAF), carbamazepine (CBZ), ketoprofen (KET), ibuprofen (IBU), diclofenac (DCL), clofibric acid (ACB), bisphenol A (BPA), and sotalol (SOT). Overall, the HD-VF-UVC system completely removed (>99.5 %) ACE, CAF, KET, IBU, DCL and ACB, and to a lesser extent SOT (98 %), BPA (83 %) and CBZ (51 %). On the other hand, the HD-VF-UVA/TiO2 system (at 2 h) achieved >99.5 % removal of ACE, CAF, KET, IBU and DCL while ACB, BPA, CBZ and SOT were degraded by 83 %, 81 %, 78 % and 68 %, respectively. Working also at 2 h of exposure time, in summer conditions, the HD-VF-Sol/TiO2 system achieved >99.5 % removal of ACE, CAF, KET, IBU, DCL and ACB, and to a minor extent BPA (80 %), SOT (74 %) and CBZ (69 %). Similar results, although slightly lower for SOT (60 %) and CBZ (59 %), were obtained in the pilot sunlight plus TiO2 catalyst unit. However, the use of sunlight irradiation with a TiO2-based photocatalyst clearly showed lower removal efficiency in autumn conditions (i.e., 47 % SOT, 31 % CBZ).

Abstract
In the past decade, recent Latinx immigrants (RLIs) from South and Central America have arrived in the United States seeking asylum from countries affected by war, political upheaval, and high crime and poverty rates. The premigration stress and trauma they experience are further compounded by postimmigration stress due to discrimination, lack of access to health care, and financial instability. Evidence suggests RLIs who experience such stress and trauma have an increased risk of developing depressive symptoms. We examined the combined effect of premigration stress and trauma and postimmigration stress on postimmigration depressive symptoms; we also explored the moderating effect of gender. Hierarchical multiple regression and moderation analyses were conducted on a cross-sectional sample of 540 young adult RLIs (age range: 18-34 years, 50.2% men) in South Florida. Higher levels of postimmigration stress, β = .37, p < .001, were associated with increased postimmigration depressive symptoms. No significant associations emerged between premigration stress and trauma and postimmigration depressive symptoms. Moderation analyses revealed no significant interaction effect of gender. Post hoc analyses indicated that country/region of origin moderated the relation between postimmigration stress and depressive symptoms such that the association was stronger among Venezuelan, β = 1.51, p < .001; other South American, β = 1.06, p < .001; and Central American/Mexican RLIs, β = 1.38, p < .001, compared with Caribbean RLIs, β = .45, p = .122. These findings suggest that interventions focused on addressing postimmigration stress early in the immigration process can potentially lower subsequent depressive symptoms among RLIs.

Abstract
The hoverfly Eristalinus aeneus is an important pollinator of crops and wild plants. However, there is a lack of detailed information about its foraging behaviour and its potential as a managed pollinator of mango. Given the growing economic importance of protected cultivation of mango, our aim is to study the flight activity and foraging behaviour of E. aeneus on this crop. Eristalinus aeneus displayed a bimodal daily activity, with peaks during mid-morning and mid-afternoon. The activity was maintained over a wide range of temperature (from 17.8 up to 37.4°C), light intensity (from 8.2 up to 57.4 klux) and relative humidity (from 19.0 up to 88.8%). The syrphids were active most of the time in this crop, and we observed five different types of activity: foraging (67%), resting (17%), flying (10%), grooming (4%) and walking (2%). This hoverfly visited hermaphrodite flowers more often than male flowers. On average, it visited 36.46 ± 13.92 flowers per 5 min, with a higher number of floral visits for nectar feeding. The duration of the visits to hermaphrodite and male flowers was similar but pollen-feeding visits lasted longer (6.44 s per flower) than nectar-feeding ones (5.51 s per flower). The highest number of visits to mango inflorescences was observed during the morning, but the longest visits occurred at midday. The implication of these results for the potential use of E. aeneus as a managed pollinator in protected cultivation of mango is discussed.

Abstract
Hispanic emerging adults are often exposed to ethnic discrimination, yet little is known about coping resources that may mitigate the effects of ethnic discrimination on psychological stress in this rapidly growing population. As such, this study aims to examine (1) the associations of ethnic discrimination, distress tolerance, and optimism with psychological stress and (2) the moderating effects of distress tolerance and optimism on the association between ethnic discrimination and psychological stress. Data were drawn from a cross-sectional study of 200 Hispanic adults ages 18-25, recruited from two urban counties in Arizona and Florida. Hierarchical multiple regression and moderation analyses were utilized to examine these associations and moderated effects. Findings indicated that higher optimism was associated with lower psychological stress. Conversely, higher ethnic discrimination was associated with higher psychological stress. Moderation analyses indicated that both distress tolerance and optimism moderated the association between ethnic discrimination and psychological stress. These study findings add to the limited literature on ethnic discrimination among Hispanic emerging adults and suggest that distress tolerance may be a key intrapersonal factor that can protect Hispanic emerging adults against the psychological stress often resulting from ethnic discrimination.

Abstract
HIV testing early in the immigration process can facilitate timely linkage to HIV prevention and treatment services for immigrants. This study aims to determine the prevalence of self-report HIV testing pre- and post-immigration and the associations between pre-immigration HIV sexual risk behaviors, access to healthcare post-immigration, and HIV testing post-immigration among young adult recent Latino immigrants. Cross-sectional data from 504 recent Latino immigrants aged 18 to 34 who immigrated to Miami-Dade County, Florida during the 12 months before assessment were analyzed using robust Poisson regression models. We found that 23.8% of participants reported HIV testing post-immigration and 56.7% reported HIV testing pre-immigration. The prevalence ratio for post-immigration HIV testing was higher for participants that had health insurance (adjusted prevalence ratio [aPR]: 1.70, 95% confidence interval [CI]: 1.21-2.38) and a regular doctor or healthcare provider after immigration (aPR: 1.43, 95% CI 1.03-2.00), and post-immigration HIV testing was higher for participants that had ever been tested for HIV before immigration (aPR: 2.41, 95% CI 1.68-3.45). Also, the prevalence ratio was lower for those who engaged in condomless sex in the three months prior to immigration (aPR: 0.65, 95% 0.47-0.90). These findings suggest that addressing barriers to healthcare and prevention services for young adult recent Latino immigrants is needed to scale-up HIV testing in this population early in the immigration process.

Abstract
Flea infestations of wild rabbits were examined monthly in central Spain in a meso-Mediterranean area for 5 yr. A total of 1,180 wild rabbits were trapped and 7,022 fleas were collected from them. Overall, the prevalence was 74.1% with a mean flea index of 5.95 fleas per rabbit. Four flea species were identified: Spilopsyllus cuniculi (Dale, 1878) was the most abundant species (accounting for 74.3% of fleas collected) followed by Xenopsylla cunicularis (Smit, 1957), Odontopsyllus quirosi (Gil Collado, 1934), and Nosopsyllus fasciatus (Bosc, 1800) (18.9, 6.7, and 0.1%, respectively). The highest prevalence was observed in S. cuniculi (48.6%) followed by X. cunicularis, O. quirosi, and N. fasciatus (34.3, 20.0, and 0.6%, respectively). Odontopsyllus quirosi and S. cuniculi were mainly collected from autumn to spring with the peak of infestation in winter, while X. cunicularis was mainly found from spring to autumn with maximum levels of infestation during the summer months. The relevance of these findings is discussed.

Abstract
A 3D printing system able to print circuits of conductive epoxy resin doped with carbon nanotubes (CNTs) is proposed. Different simple circuits, more specifically lines and strain gauge patterns, made of resins reinforced with 0.3, 0.5, 0.8 and 1 wt% of CNTs were printed on the surface of glass fiber laminates. It was observed that increasing the CNT content reduced the wettability of the printed circuits on the glass fiber substrate. In every case the contact angle was far below 90°. Furthermore, the strain sensing capabilities were analyzed under a flexural load. The results showed that the sensitivity increased with CNT content (with gauge factor values from 1.5 to 2.5) as a result of the prevalent effect of well-dispersed areas due to a reduction in the tunneling distance. On the other hand, the strain gauges showed a lower sensitivity (around 20%-40% less, depending on the condition) compared with line circuits due to localized compressive effects. Furthermore, good repeatability of the strain sensors was proved during cycling tests, with similar baseline and peak values for the electrical resistance in each cycle. Therefore, the proposed materials have a high potential for applications in structural health monitoring.

Abstract
Latina immigrants living in farmworker communities are a population in need of HIV risk reduction interventions due to their high risk for HIV and their limited access to health care and prevention services. The present study is the first to evaluate the efficacy of SEPA intervention on a cohort of 234 pre-established Latina immigrants living in farmworker communities in South Florida. SEPA is a CDC evidenced-based and Latinx culturally tailored HIV risk reduction intervention. Data were collected through structured interviews at baseline and 6-months post intervention and were analyzed using generalized linear mixed modeling. Results showed that SEPA was effective on increasing condom use during vaginal and anal sex with male partners, self-efficacy for condom use, intentions to negotiate safe sex and HIV-related knowledge from baseline to 6-months post intervention. These findings contribute to the evidence supporting the efficacy of SEPA by confirming previous results and demonstrating the efficacy of this intervention for Latinas of diverse backgrounds.

Abstract
Most studies on psychosocial stress among Hispanics have focused on risk factors. To better understand psychosocial stress among this population, this study aimed to examine components of bicultural identity integration and bicultural self-efficacy, that may be associated with lower psychosocial stress among Hispanic emerging adults (ages 18-25). This aim was tested on a cross-sectional sample of Hispanic emerging adults (Mage = 21.30, SD = 2.09) that included 200 participants (Arizona n = 99, Florida n = 101). The sample included men (n = 98) and women (n = 102). Most participants were US-born (70%), college students (69.5%), and of Mexican heritage (44%). Standardized coefficients from a hierarchical multiple regression model indicate that higher levels of the bicultural harmony component of bicultural identity integration (β = -0.26, p < 0.001) and the social groundedness component of bicultural self-efficacy (β = -0.23, p < 0.01) were associated with lower levels of psychosocial stress. To our knowledge, this is the first study to examine components of bicultural identity integration and bicultural self-efficacy and their respective associations with psychosocial stress among any racial/ethnic group. Thus, more studies are needed to replicate our findings to determine if bicultural identity integration and bicultural self-efficacy should be considered in psychosocial stress interventions for Hispanics.

Abstract
Introduction Postictal suppression (PSI) is considered a key feature for ECT’s outcomes because higher values have been correlated with clinical efficacy. However, little is known about the demographic factors influencing this parameter. Objectives To analyze the influence of sex, age, diagnosis and treatment phase on ECT efficacy measured with PSI value. Methods 3251 ECT sessions were performed on 182 patients during two years at a university hospital. PSI was retrospectively analyzed comparing it according to sex (male, female), age, main diagnosis (major depressive disorder [MDD], bipolar disorder [BD], schizoaffective disorder [SZA], schizophrenia [SCZ]) and treatment phase (acute [a-ECT], continuation [c-ECT], maintenance [m-ECT]). Results PSI values were 69.76 % (SD 17.05) in women and 70.72 % (SD 16.81) in men without differences between sexes (F=0.979; p=0.607). PSI was correlated with age (r=-0.058; p=0.031). MDD PSI was 70.01 % (SD 16.88), for BD it was 69.48 % (SD 17.00), for SZA it was 68.62 % (SD 17.39), and for SCZ it was 70.73 % (SD 17.18), without differences between diagnosis (F=1.085; p=0.141). According to treatment phase, PSI in the a-ECT was 72.26 % (SD 16.43), in the c-ECT it was 67.83 % (SD 17.53), and in the m-ECT it was 68.47 % (SD 17.02), without differences between phases (F=0.901; p=0.915). Conclusions Although there exist statistically significant association between age and PSI it is a negligible correlation with no clinical relevance. Thus, we conclude that neither sex nor age, nor diagnosis, nor treatment phase seem to influence PSI to a relevant degree. Disclosure No significant relationships.

Abstract
The Ría de Ortigueira is an environmentally well conserved; however, the sediments show high concentrations of toxic elements. In some zones, the concentrations of Ni (60-1080 mg kg-1) and Cr (9-567 mg kg-1) were extremely high, while the concentrations of other toxic elements were within normal ranges. PCA revealed that metal enrichment was due to dumping of waste sludge from a peridotite mine. The study of marine currents showed that the exit of the contaminated waste towards the external zone is restricted by the low energy of the residual currents, and the sludge therefore remains trapped in the internal zones. The potential ecological risk was moderate for all areas of the ría, reaching high values close to the mouth of the river Landoi. Finally, geochemical fractioning showed that most of the metals are associated with Fe oxyhydroxides which can become unstable and release adsorbed or coprecipitated metals, especially Ni.

Abstract
METHOD Two hundred Hispanic emerging adults from Arizona (n = 99) and Florida (n = 101) completed a cross-sectional survey, and data were analyzed using hierarchical multiple regression and moderation analyses. RESULTS Higher social media discrimination was associated with higher symptoms of depression and generalized anxiety. Moderation analyses indicated that higher social media discrimination was only associated with symptoms of depression and generalized anxiety among men, but not women. CONCLUSION This is likely the first study on social media discrimination and mental health among emerging adults; thus, expanding this emerging field of research to a distinct developmental period.

Abstract
Abstract
Background
Maternal mortality remains a serious challenge worldwide, it being part of the Sustainable Development Goals. Progress is tracked through maternal mortality ratios (MMR), which demonstrate the current development of a health system. Our study describes tendencies and factors involved in the MMR in Paraguay, South America.
Methods
A retrospective cross-sectional study was undertaken. Data were extracted from the national system of vital statistics published by the Ministry of Public Health and Social Welfare. MMR was expressed as the number of maternal deaths per 100,000 live births. The causes of maternal deaths were classified according to the CIE-10. The tendency and fluctuations of the variables were analyzed through Pearson and Spearman correlations. A significance level of 5% was established.
Results
During the period of 2004-2015 in Paraguay there was a significant reduction in the tendency of the number of maternal deaths (r= -0.895; p < 0.001) with a decrease of 37.1%; Accordingly, there is a decreased tendency of the MMR (r= -0.929; p < 0.001) with a reduction of 45.4% and an annual mean decrease of 3.95%. It was observed that women aged 40 years and older and women characterized as single possessed a higher MMR, with each group showing 317.7/100 000 and 377.5/100 000, respectively. The 75% of death causes were Postpartum Hemorrhage, Eclampsia, Concurrent maternal deaths, Abortion and Puerperal Sepsis.
Conclusions
Our study showed significant decreased tendency of MMR, although remaining high compared to high income countries. More studies to support this result are recommended due to the difference with international estimates. The main causes of death showed the need to strengthen prenatal follow-up in primary care far from high-complexity hospitals.
Key messages
Our study describes the situation on Maternal Mortality in a developing country, showing the importance of health care access and prenatal follow up for preventable complications. Our work showed the urgent need for more studies about abortion prevalence and also to determine the cause of higher MMR on single women in our country.

Abstract
OBJECTIVE This study aimed to (1) examine respective associations of acculturation orientations (e.g., U.S. orientation and Hispanic orientation) and domains (e.g., social groundedness and role repertoire) of bicultural self-efficacy, the perceived confidence to function effectively within the receiving culture and the heritage culture, with alcohol use severity among Hispanic emerging adults. This study also aimed to (2) examine potential moderating factors of respective associations among acculturation orientations and bicultural self-efficacy with alcohol use severity. METHOD 200 Hispanic emerging adults from Arizona (n = 99) and Florida (n = 101) completed a cross-sectional survey. Inclusion criteria were being ages 18-25, self-identify as Hispanic or Latina/o, and currently living in Maricopa County or Miami-Dade County. Data were analyzed using hierarchical multiple regression and moderation analyses. RESULTS Findings indicate that neither of the acculturation orientations nor role repertoire had main effects with alcohol use severity. However, higher social groundedness was associated with lower alcohol use severity. Moderation analyses indicate that the interaction between the U.S. orientation and study site and the interaction between the Hispanic orientation and social groundedness were statistically significant in relation to alcohol use severity. CONCLUSIONS Considering that the U.S. orientation was associated with alcohol use severity only in Arizona highlights the need for multisite studies on acculturation. Our findings demonstrate that other sociocultural processes such as acculturation can impact bicultural self-efficacy; and that the association between bicultural self-efficacy and alcohol merits further investigation. However, more thorough assessments of bicultural self-efficacy are needed to better understand its effects on alcohol.

Abstract
Background:Lung involvement is frequent in ANCA-associated vasculitis (AAV). Classical lung manifestations consist of capillaritis with lung haemorrhage, inflammatory infiltrates and nodules. Interstitial lung disease (ILD) is increasingly recognized among patients with AAV. However, little is known concerning risk factors and clinical course of these patients.Objectives:The aim of our study was to characterize the prevalence and clinical course of ILD in patients with AAV.Methods:We have performed a clinical retrospective single-centre observational analysis (1990-2019) of all patients with the diagnosis of microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) diagnosed according to 2018 Draft Classification Criteria for GPA and MPA1. Demographic, clinical and immunologic data were reviewed. Radiologic pattern of ILD were assessed by high-resolution-CT. Main outcome evaluated was overall-all survival.Results:The study population consisted of 123 patients, 56% female, aged 59.3±18.2 years old at the time of diagnosis. Clinical diagnosis was of MPA in 54% of patients and GPA in 46%. While 108 (88%) ANCA positive patients had PR3 (n=25) or MPO (n=83), 15 (12%) patients had negative or atypical ANCA. Any lung involvement was present in 82 (71%) and ILD was identified in 24 (20%) of all patients. ILD pattern was of usual interstitial pneumonia (UIP) in 12 patients, non-specified interstitial pneumonia (NSIP) in 9 and chronic organizing pneumonia (OP) in 3. There was an association between the presence of ILD and ANCA specificity: MPO were present in 100% of patients with UIP and in 75% of patients with NSIP/OP (p=0.017). Bronchiectasis were more prevalent among patients with ILD (19/24; p<0.001). During the median follow-up time period of 68 (23-126) months, mortality was of 42% among patients with ILD-AAV compared with 11% in no ILD-AAV (log-rank p=0.0001). On the multivariate Cox regression model, ILD was an independent predictor of mortality HR 2.95 (95%CI 1.09-7.96; p=0.033).Conclusion:ILD is a frequent manifestation of MPA and GPA patients. The presence of ILD, particularly UIP, is associated with ANCA-MPO and is a predictor of mortality. Therefore, a better management of fibrotic lung involvement in AAV is warranted.References:[1]Robson JC, Grayson PC, Ponte C, et al.

Abstract
Background Efforts in the prevention and treatment of depression among Hispanic immigrant women require studies to identify modifiable factors of depression. Some factors that may merit investigation are gender roles such as egalitarian gender attitudes, marianismo, and self-silencing. Methods This cross-sectional study included 231 Hispanic immigrant women living in Miami-Dade County, Florida. Logistic regression was used to examine associations of covariates, egalitarian gender attitudes, marianismo, and self-silencing in relation to depression. Results Egalitarian gender attitudes were not associated with depression. For marianismo domains, higher scores on the spiritual pillar scale were associated with lower odds of depression. With regard to self-silencing, higher scores on externalizing self-perception and divided self were associated with higher odds of depression. Conclusions Findings add to the limited literature on depression among Hispanic immigrants and provides some insight on sociocultural factors that may be considered in depression interventions for Hispanic immigrant women.

Abstract
Emerging adulthood has been described as a difficult stage in life and may be particularly stressful for Hispanic emerging adults who are disproportionately exposed to adversity and chronic sociocultural stressors. To better prevent and treat depressive disorders among Hispanic emerging adults, more research is needed to identify and understand modifiable determinants that can help this population enhance their capacity to offset and recover from adversity and sociocultural stressors. As such, this study aimed to (1) examine the association between resilience and depressive symptoms among Hispanic emerging adults, and (2) examine the extent to which intrapersonal resources (e.g., mindfulness, distress tolerance, emotion regulation strategies) and interpersonal resources (e.g., family cohesion, social support) moderate the association between resilience and depressive symptoms. To examine these aims, 200 Hispanic emerging adults (ages 18-25) from Arizona (n = 99) and Florida (n = 101) completed a cross-sectional survey, and data were analyzed using hierarchical multiple regression and moderation analyses. Findings from the hierarchical multiple regression indicate that higher resilience was associated with lower depressive symptoms. Findings from the moderation analyses indicate that family cohesion, social support, and emotion regulation strategies (e.g., cognitive reappraisal and expressive suppression) functioned as moderators; however, mindfulness and distress tolerance were not significant moderators. Findings from this study add to the limited literature on resilience among Hispanics that have used validated measures of resilience. Furthermore, we advance our understanding of who may benefit most from higher resilience based on levels of intrapersonal and interpersonal resources.

Abstract
OBJECTIVES The objective of this study is to analyze the impact (in terms of safety and saving of hospital costs) of the implementation of a new protocol for the correction of pelvic organ prolapse (POP) by minimally invasive sacrocolpopexy (MISC) with 24-hour hospital stay. MATERIAL AND METHODS Prospective observational study of the first 78 MISC procedures performed consecutively. 46 procedures (59%) were performed with 24-hour hospital stay, and 32 (41%) required more than 24hours. The postoperative complications were determined for each group: visits to the Emergency Department, reoperations, and the average cost per procedure regarding hospital stay and ER visits. The cost model was established according to the data of the Analytical Accounting System of the Jiménez Díaz Foundation Hospital and of the Official State Gazette of Madrid. RESULTS There were no differences regarding intraoperative or postoperative complications between both groups. The number of visits to the Emergency Department, reinterventions or hospital re-admissions was lower in the 24-hour hospital stay group, without reaching statistical significance. The implementation of the MISC protocol with 24-hour hospital stay represented a saving of 607.91€ per procedure in hospital costs. CONCLUSIONS Correction of the POP with MISC with a 24-hour hospital discharge policy was feasible and safe in at least 59% of the patients, with similar complications, visits to the Emergency Department or hospital readmission rates.

Abstract
Chemically-driven isothermal close space vapour transport was used to prepare pure MoO2 thin films which were eventually converted to MoO3 by annealing in air. According to temperature-dependent Raman measurements, the MoO2/MoO3 phase transformation was found to occur in the 225 °C-350 °C range while no other phases were detected during the transition. A clear change in composition as well as noticeable modifications of the band gap and the absorption coefficient confirmed the conversion from MoO2 to MoO3. An extensive characterization of these two pure phases was carried out. In particular, a procedure was developed to determine the dispersion relation of the refractive index of MoO2 from the shift of the interference fringes of the used SiO2/Si substrate. The obtained data of the refractive index was corrected taking into account the porosity of the samples calculated from elastic backscattering spectrometry. The Debye temperature and the residual resistivity were extracted from the electrical resistivity temperature dependence using the Bloch-Grüneisen equation. MoO3 converted samples presented a very high resistivity and a typical semiconducting behavior. They also showed intense and broad luminescence spectra composed by several contributions whose temperature behavior was examined. Furthermore, surface photovoltage spectra were taken and their relation with the photoluminescence is discussed.

Abstract
BACKGROUND Both the nature and number of a wide range of prodromal symptoms have been related to the severity and type of psychopathology in the psychotic phase. However, at present there is an incomplete picture focused mainly on the positive pre-psychotic dimension. AIM To characterize the prodromal phase retrospectively, examining the number and nature of prodromal symptoms as well as their relationship with psychopathology at the onset of first-episode psychosis. METHODS Retrospective study of 79 patients experiencing a first-episode psychosis of less than 1 year from the onset of full-blown psychosis. All patients were evaluated with a comprehensive battery of instruments including socio-demographic and clinical questionnaire, IRAOS interview, PANSS, stressful life events scale (PERI) and WAIS/WISC (vocabulary subtest). Bivariate associations and multiple regression analysis were performed. RESULTS Regression models revealed that several prodromal dimensions of IRAOS (delusions, affect, language, behaviour and non-hallucinatory disturbances of perception) predicted the onset of psychosis, with positive (22.4% of the variance) and disorganized (25.6% of the variance) dimensions being the most widely explained. CONCLUSION In addition to attenuated positive symptoms, other symptoms such as affective, behavioural and language disturbances should also be considered in the definitions criteria of at-high-risk people.

Abstract
BACKGROUND In Mexico, 80% women with cervical cancer are diagnosed at locally advanced stages and are treated with concomitant chemoradiotherapy. The treatment modality and catabolic state confer a nutritional risk. The present study aimed to thoroughly evaluate the nutritional status and change in body composition of locally advanced cervical cancer (LACC) patients throughout treatment. METHODS An observational prospective study, carried out at the Mexican National Cancer Institute, included 55 LACC patients. Nutritional status was evaluated before, during and after treatment, using anthropometric, dietary and biochemical measurements. Body composition was analysed using computed tomography images obtained at the time of diagnosis and approximately 4 months after treatment completion. Clinical outcomes were associated with changes in body composition. RESULTS At the time of diagnosis, no patients were clinically malnourished, although 33.3% presented sarcopenia and most were overweight; by the end of treatment, 69% became clinically malnourished and 58% were sarcopenic. Average weight loss was 7.4 kg (P = 0.001). Adequacy of energy intake was reduced to 54%, obtained predominantly from carbohydrates. By the week 9, 62.8% patients became anemic and 34.5% had low albumin levels. Body composition analysis revealed that patients lost both, muscle and adipose tissues, although 27% patients were muscle depleted by the end of treatment. Patients who lost ≥10% skeletal muscle presented a higher tumour recurrence (hazard ratio = 2.957, P = 0.006) and a tendency towards diminished overall survival (hazard ratio = 2.572, not significant). CONCLUSIONS The nutritional status of cervical cancer patients deteriorates during treatment with concomitant chemoradiotherapy and, most importantly, muscle loss impacts the clinical outcome of patients.

Abstract
Latinas in farmworker communities are at particularly higher risk for human immunodeficiency virus (HIV) due to the vulnerable circumstances they experience. However, little is known about the factors influencing HIV prevention behaviors in this population. The aim of this study was to examine the associations of self-silencing behaviors and egalitarian attitudes toward women in relation to three HIV prevention behaviors: self-efficacy for HIV prevention, intentions to negotiate safe sex, and HIV-related knowledge. This study is a cross-sectional analysis that used hierarchical multiple regression models to examine these previously mentioned associations, among Latina immigrant farmworkers from Miami-Dade County, Florida (n = 232). Findings indicated that self-silencing behaviors were adversely associated with the three HIV preventive behaviors whereas egalitarian attitudes were positively associated. Findings from this study may help to advance the understanding of sociocultural determinants of HIV prevention behaviors among Latina immigrants.

Impact of pretransplant CMV-specific T-cell immune response in the control of CMV infection after solid organ transplantation: a prospective cohort study. Clin Microbiol Infect 2018; 25:753-758.

Abstract
INTRODUCTION Although solid organ transplant (SOT) recipients with pretransplant serology for cytomegalovirus (CMV-R+) are considered at intermediate risk for CMV infection post transplantation, CMV infection remains a major cause of morbidity in this population. We prospectively characterized whether having pretransplant CMV-specific cellular immunity is independently associated with controlling infection after transplantation in R + SOT recipients. METHODS A prospective cohort of consecutive R + SOT recipients that received pre-emptive treatment for CMV infection was monitored after transplantation and variables were recorded during the follow-up. The cytomegalovirus-specific T-cell immune response was characterized by intracellular cytokine staining and viral loads determined using real-time PCR. RESULTS One hundred and thirty-five R + SOT recipients were included (67 kidney, 64 liver, four liver-kidney). Only one-third of the patients (42; 31.85%) had CMV-specific T-cell immunity (CD8+CD69+INF-γ+ T cells >0.25%) before transplantation. Patients with negative pretransplant immunity had more CMV infection (49, 52.7% vs. 15, 35.7%; p 0.07) and received more antiviral therapy than those with immunity (32, 34.4% vs. 6, 14.3%, p 0.016). Having CMV specific immunity was an independent factor for protection from developing viraemia ≥2000 IU/mL (OR 0.276, 95% CI 0.105-0.725, p < 0.01) and lower administration of treatment (OR 0.398, 95% CI 0.175-0.905, p 0.028). Only patients with no pretransplant CMV-specific T-cell response were diagnosed with CMV-disease (8, 8.6% vs. 0, 0%, p 0.05). DISCUSSION Our results show that having a pretransplant CMV specific T-cell response may be associated with a lower rate of CMV viraemia and less antiviral treatment after transplantation; however, more prospective studies are needed to confirm these findings.
