Abstract
BACKGROUND Human papillomavirus (HPV) 16 non-A lineage variants have higher carcinogenic potential for cervical cancer. HPV-16 variants natural history among males is not established. We evaluated HPV-16 variants prevalence and persistence in the external genitalia of men enrolled in the prospective HPV Infection in Men (HIM) Study. METHODS The HIM Study included men from the United States, Brazil, and Mexico. HPV-16 variants were distinguished using polymerase chain reaction sequencing. The prevalence of HPV-16 variants was assessed, and associations with infection persistence were estimated. RESULTS We characterized the HPV-16 variants for 1700 genital swab samples from 753 men and 22 external genital lesions in 17 men. The prevalence of HPV-16 lineages differed by country and marital status (P < .001). Overall, 90.9% of participants harbored lineage A variants. The prevalence of non-A lineages was heterogenous among countries. HPV-16 lineage A variants were associated with a 2.69-fold increased risk of long-term persistent infections compared with non-A lineages. All high-grade penile intraepithelial neoplasia harbored lineage A variants and occurred in the context of long-term persistent infections with the same variants. CONCLUSIONS The prevalence and persistence of HPV-16 variants observed at the male external genitalia suggest differences in the natural history of these variants between men and women, which may be associated with intrinsic differences in the infected genital epithelia.

Abstract
Objective: Triple negative breast cancer (TNBC) has high relapse rates due to dysregulated inflammatory signaling pathways and significant changes in the tumor microenvironment, probably influencing the failure of several therapies. The Cysteinyl Leukotriene Receptor 1 (CYSLTR1), a leukotriene modulator of inflammation, has been shown to play an important role in cancer pathogenesis and survival but few studies have been reported on its role in breast cancer. Materials and Methods: The present work was conducted using publicly available platforms that have omics data to assess the clinical potential of CYSLTR1 expression and its prognostic validation in large cohorts of samples from breast cancer patients. Web platforms containing clinical information, RNA-seq and protein data were selected to perform in silico analyses of the potential marker CYLSTR1. Added together, the platforms included modules for correlation, expression, prognosis, drug interactions, and construction of gene networks. Results: Kaplan–Meier curves revealed that reduced levels of CYSLTR1 corresponded to an unfavorable outcome for overall survival (p<0.005) as well as relapse-free survival (p<0.001) in the basal subtype. Additionally, CYSLTR1 was downregulated in breast tumor samples compared to adjacent healthy tissue (p<0.01) and the basal subtype exhibited the lowest expression of CYSLTR1 relative to the other subtypes (p<0.0001). Furthermore, gene networking analysis showed strong associations of CYSLTR1 with two protein-coding genes (P2RY10 and XCR1) when tested on a TNBC dataset. Conclusion: Our data highlighted the relevance of CYSLTR1 since it may play an important role in TNBC therapy. However, further in vitro and in vivo studies should be directed towards validating our findings in an effort to improve our understanding of TNBC pathology.

Abstract
BACKGROUND The prevalence of Human Papillomavirus type 16 (HPV-16) variants in men and the association with tumor development has not been fully investigated. We estimated the prevalence of genital, anal, and oral HPV-16 infections in men through a systematic review and meta-analysis. METHODS Seven databases were searched and included studies that identified HPV-16 positive males, HPV-16 variants (lineages/sublineages), and indicated the sample's anatomical origin. This protocol is registered in PROSPERO (CRD42020178013). RESULTS The database searches yielded 14 studies including 445 HPV-16 positive samples classified as lineage A (n = 390), lineage D (n = 43), lineage B (n = 10), and lineage C (n = 2) variants. Lineage A variants predominated among the anatomical sites and the diverse geographical regions. CONCLUSIONS HPV-16 lineages vary according to anatomical and geographical region. According to this preliminary evaluation of the current literature, we hypothesize that, similar to women, specific HPV-16 variants may also be associated to increased cancer risk in men.

Abstract
Several studies have pointed to the potential benefits of riparian vegetation as buffer zones for agricultural and industrial pollutants harmful to aquatic ecosystems. However, other studies have called into question its use as an ecological filter, questioning the widths and conditions for which they are effective as a filter. In this work, we have investigated the buffering capacity of the riparian one to retain pesticides in the water-saturated zone, on 27 sites composed by riparian buffer zones with different vegetation structure (woody, shrubs, or grass vegetation) and width (12, 36, and 60 m). Five pesticides were analyzed. The effectiveness of the filtering was largely influenced by the width and vegetation type of the buffer zone. In general, decreasing pesticide removal followed in this order wood > shrubs > grass. The 60 m woody buffer zone was the most effective in the removal of all the pesticides. Only atrazine was detected in this case (0.3 μg L(-1)). Furthermore, a linear correlation (R (2) > 0.97) was observed in their removal for all compounds and buffer zones studied. Thus, preserving the woody vegetation in the riparian zone is important for watershed management and groundwater quality in the no-tillage system in temperate climate.

Abstract
In the Azores archipelago, a significant proportion of buildings are infested with the urban exotic drywood termite Cryptotermes brevis (Walker), causing major economical and patrimonial losses. This work aims to understand the potential spread of this termite species in the Azores and estimate the costs for both treatment and reconstruction of infested buildings in the entire archipelago. A maximum entropy niche modeling process was used to determine the potential occurrence of the species on each island. Different scenarios were built using independent global and regional incidence and environmental data. Both projections reveal the same pattern. Generally, the probability of occurrence is higher near the coast line, where, in Azores, the majority of the towns and villages are located. We also predict that the infestation has potential to spread to yet unaffected towns and islands. It is estimated that the cost of treating all currently infested buildings in the archipelago is Euro 51 million, while reconstruction of the same buildings would rise the costs to Euro 175 million. We predict that the absence of a control strategy will cause a further expansion of the pest to more localities in the Azores. An estimate to future scenarios implies higher costs, with treatment and rebuilding values rising up to eight times the current values.

Abstract
In this work we compare two Iberian and a pan-European fish-based methods to assess ecological quality in rivers: the Fish-based Index of Biotic Integrity for Portuguese Wadeable Streams (F-IBIP), the Mediterranean Index of Biotic Integrity (IBIMED) and the pan-European Fish Index (EFI+). The results presented herein were developed in the context of the 2nd phase of the Intercalibration Exercise (IC), as required by the Water Frame Directive (WFD). The IC is aimed at ensuring comparability of the quality boundaries among the different WFD assessment methods developed by the Member States for each biological quality element. Although the two national assessment methods were developed for very distinct regions of Iberia (Western and Eastern Iberian Peninsula) they share the same methodological background: both are type-specific and guild-based multimetric indices. EFI+ is a multimetric guild-based model, but it is site-specific and uses a predictive modelling approach. The three indices were computed for all sites included in the Iberian Intercalibration database to allow the direct comparison, by means of linear regressions, of the resulting three quality values per site. The quality boundary harmonization between the two Iberian methods was only possible through an indirect comparison between the two indices, using EFI+ as a common metric. The three indices were also shown to be responsive to a common set of human induced pressures. This study highlights the need to develop general assessment methods adapted to wide geographical ranges with high species turnover to help intercalibrating assessment methods tailored for geographically more restricted regions.

Abstract
The present report describes a three-step approach that was used to characterize and define thresholds for the Least Disturbed Condition in Mediterranean streams of four different types, regarding organic pollution and nutrients, hydrological and morphological alterations, and land use. For this purpose, a common database composed of national reference sites (929 records) from seven countries, sampled for invertebrates, diatoms and macrophytes was used. The analyses of reference sites showed that small (catchment <100 km(2)) siliceous and non-siliceous streams were mainly affected by channelization, bank alteration and hydropeaking. Medium-sized siliceous rivers were the most affected by stressors: 25-43% of the samples showed at least slight alterations regarding channelization, connectivity, upstream dam influence, hydropeaking and degradation of riparian vegetation. Temporary streams were the least affected by hydromorphological changes, but they were nevertheless affected by alterations in riparian vegetation. There were no major differences between all permanent stream types regarding water quality, but temporary streams showed lower values for oxygenation (DO) and wider ranges for other variables, such as nitrates. A lower threshold value for DO (60%) was determined for this stream type and can be attributed to the streams' natural characteristics. For all other river types, common limits were found for the remaining variables (ammonium, nitrate, phosphate, total P, % of artificial areas, % of intensive and extensive agriculture, % of semi-natural areas in the catchment). These values were then used to select the list of reference sites. The biological communities were characterized, revealing the existence of nine groups of Mediterranean invertebrate communities, six for diatoms and five for macrophytes: each group was characterized by specific indicator taxa that highlighted the differences between groups.

Abstract
This paper exposes a new methodological approach to solve the problem of intercalibrating river quality national methods when a common metric is lacking and most of the countries share the same Water Framework Directive (WFD) assessment method. We provide recommendations for similar works in future concerning the assessment of ecological accuracy and highlight the importance of a good common ground to make feasible the scientific work beyond the intercalibration. The approach herein presented was applied to highly seasonal rivers of the Mediterranean Geographical Intercalibration Group for the Biological Quality Element Macrophytes. The Mediterranean Group of river macrophytes involved seven countries and two assessment methods with similar acquisition data and assessment concept: the Macrophyte Biological Index for Rivers (IBMR) for Cyprus, France, Greece, Italy, Portugal and Spain, and the River Macrophyte Index (RMI) for Slovenia. Database included 318 sites of which 78 were considered as benchmarks. The boundary harmonization was performed for common WFD-assessment methods (all countries except Slovenia) using the median of the Good/Moderate and High/Good boundaries of all countries. Then, whenever possible, the Slovenian method, RMI was computed for the entire database. The IBMR was also computed for the Slovenian sites and was regressed against RMI in order to check the relatedness of methods (R(2)=0.45; p<0.00001) and to convert RMI boundaries into the IBMR scale. The boundary bias of RMI was computed using direct comparison of classification and the median boundary values following boundary harmonization. The average absolute class differences after harmonization is 26% and the percentage of classifications differing by half of a quality class is also small (16.4%). This multi-step approach to the intercalibration was endorsed by the WFD Regulatory Committee.

Abstract
The termite Cryptotermes brevis (Walker) (Isoptera: Kalotermitidae) is an urban pest that causes much damage to wood structures. Little has been done concerning the use of control methods for alates. C. brevis is known to have phototropic behavior during the dispersal flights, and this knowledge has been applied for preventative control in the Azores where this species is a serious urban pest. We were interested in determining whether there was a light wavelength preference by the alates of C. brevis to optimize light traps against this species. Six light wavelengths were tested: 395 nm (UV), 460-555 nm (white), 470 nm (blue), 525 nm (green), 590 nm (yellow), and 625 nm (red) in choice chambers, with dark chambers as controls. Two populations were tested, one population in Florida and one population in the Azores (Terceira Island). We found consistent results for both populations, with a preference for the light wavelengths in the white, blue, and green spectrum (460-550 nm). This information can be used to build more effective light traps that can be used by home owners in the Azores to help control this pest.

Abstract
The high incidence and low resolution of the pain after surgery are shown in international literature. During the five days after the cardiac and abdominal surgery, these patients were asked once a day about their pain. Nearly 50% of the patients answers showed pain complaints. At the cardiac patients 47% did not take treatment during the last four hours, although the medicine was prescribed by the doctor to be used in eventual necessity. Similar occurrences happened with abdominal patients where no medicine was given in 68.2% events of their pain complaints. So, we find that the under-identification and undertreatment of the pain are like the other studies.

Abstract
Portuguese immigration is a relatively new addition to the Canadian ethnic mosaic. To help the Canadian family doctor become familiar with this new group, the experience of a predominantly Portuguese family practice is described. The main areas of concern centre around the working wife, the problems created by the uprooting of old people and the adaptation of the children to this new environment. Some conflicts created in the family by the new situation are described and solutions suggested.
