    Abstract: We evaluated the impact of continued 13-valent pneumococcal conjugate vaccine (PCV13) use in the private market (uptake of 61%) in pediatric invasive pneumococcal disease (pIPD) in Portugal (2012–2015). The most frequently detected serotypes were: 3 (n = 32, 13.8%), 14 (n = 23, 9.9%), 1 (n = 23, 9.9%), 7F (n = 15, 6.4%), 19A (n = 13, 5.6%), 6B and 15B/C (both n = 12, 5.2%), and 24F, 10A and 12B (all with n = 10, 4.3%). Taken together, non-PCV13 serotypes were responsible for 42.2% of pIPD with a known serotype. The use of PCR to detect and serotype pneumococci in both pleural and cerebrospinal fluid samples contributed to 18.1% (n = 47) of all pIPD. Serotype 3 was mostly detected by PCR (n = 21/32, 65.6%) and resulted from a relevant number of vaccine failures. The incidence of pIPD varied in the different age groups but without a clear trend. There were no obvious declines of the incidence of pIPD due to serotypes included in any of the PCVs, and PCV13 serotypes still accounted for the majority of pIPD (57.8%). Our study indicates that a higher vaccination uptake may be necessary to realize the full benefits of PCVs, even after 15 years of moderate use, and highlights the importance of using molecular methods in pIPD surveillance, since these can lead to substantially increased case ascertainment and identification of particular serotypes as causes of pIPD.

    Abstract: Mammals are threatened worldwide, with ~26% of all species being included in the IUCN threatened categories. This overall pattern is primarily associated with habitat loss or degradation, and human persecution for terrestrial mammals, and pollution, open net fishing, climate change, and prey depletion for marine mammals. Mammals play a key role in maintaining ecosystems functionality and resilience, and therefore information on their distribution is crucial to delineate and support conservation actions. MAMMALS IN PORTUGAL is a publicly available data set compiling unpublished georeferenced occurrence records of 92 terrestrial, volant, and marine mammals in mainland Portugal and archipelagos of the Azores and Madeira that includes 105,026 data entries between 1873 and 2021 (72% of the data occurring in 2000 and 2021). The methods used to collect the data were: live observations/captures (43%), sign surveys (35%), camera trapping (16%), bioacoustics surveys (4%) and radiotracking, and inquiries that represent less than 1% of the records. The data set includes 13 types of records: (1) burrows | soil mounds | tunnel, (2) capture, (3) colony, (4) dead animal | hair | skulls | jaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8), observation in shelters, (9) photo trapping | video, (10) predators diet | pellets | pine cones/nuts, (11) scat | track | ditch, (12) telemetry and (13) vocalization | echolocation. The spatial uncertainty of most records ranges between 0 and 100 m (76%). Rodentia ( n  =31,573) has the highest number of records followed by Chiroptera ( n  = 18,857), Carnivora ( n  = 18,594), Lagomorpha ( n  = 17,496), Cetartiodactyla ( n  = 11,568) and Eulipotyphla ( n  = 7008). The data set includes records of species classified by the IUCN as threatened (e.g., Oryctolagus cuniculus [ n  = 12,159], Monachus monachus [ n  = 1,512], and Lynx pardinus [ n  = 197]). We believe that th is data set may stimulate the publication of other European countries data sets that would certainly contribute to ecology and conservation‐related research, and therefore assisting on the development of more accurate and tailored conservation management strategies for each species. There are no copyright restrictions; please cite this data paper when the data are used in publications.

    Abstract: Genomic surveillance of SARS-CoV-2 in Portugal was rapidly implemented by the National Institute of Health in the early stages of the COVID-19 epidemic, in collaboration with more than 50 laboratories distributed nationwide. Methods By applying recent phylodynamic models that allow integration of individual-based travel history, we reconstructed and characterized the spatio-temporal dynamics of SARS-CoV-2 introductions and early dissemination in Portugal. Results We detected at least 277 independent SARS-CoV-2 introductions, mostly from European countries (namely the United Kingdom, Spain, France, Italy, and Switzerland), which were consistent with the countries with the highest connectivity with Portugal. Although most introductions were estimated to have occurred during early March 2020, it is likely that SARS-CoV-2 was silently circulating in Portugal throughout February, before the first cases were confirmed. Conclusions Here we conclude that the earlier implementation of measures could have minimized the number of introductions and subsequent virus expansion in Portugal. This study lays the foundation for genomic epidemiology of SARS-CoV-2 in Portugal, and highlights the need for systematic and geographically-representative genomic surveillance.

    Abstract: The shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis , concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora.

This study aimed to evaluate the associations between exit-site (ES) care protocols and the annual incidence rates of ESi and peritonitis in Portugal. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 We performed a national survey using two questionnaires: one about the incidence of catheter-related infections and the other characterizing patients’ education and ES care protocols. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 In 2017 and 2018, 14 Portuguese units followed 764 and 689 patients. ESi incidence rate was 0.41 episodes/year, and the peritonitis incidence rate was 0.37. All units monitor catheter-related infections on a yearly basis, use antibiotic prophylaxis at the time of catheter placement, and treat nasal carriage of 〈 i 〉 S. aureus 〈 /i 〉 , although with different approaches. Screening for nasal carriage of 〈 i 〉 S. aureus 〈 /i 〉 is performed by 12 units, and daily topical antibiotic cream is recommended by 6 out of 14 of the units. We did not find statistical differences in ESi/peritonitis, comparing these practices. The rate of ESis was lower with nonocclusive dressing immediately after catheter insertion, bathing without ES dressing, with the use of colostomy bags in beach baths and was higher with the use of bath sponge. The peritonitis rate was lower with bathing without ES dressing and if shaving of the external cuff was performed in the presence of chronic ESi. 〈 b 〉 〈 i 〉 Conclusions: 〈 /i 〉 〈 /b 〉 We found potential proceedings associated with ESi and peritonitis. A regular national audit of peritoneal dialysis units is an important tool for clarifying the best procedures for reduction of catheter-related infections.

    Abstract: The report of peritoneal protein loss should be related with a timely collection (24-hour measurement or 4-hour PET assessment) or concentration. Standardized and reproducible estimation of peritoneal protein transport is obtained during PET. The 24-hour measurements estimate the real amount of PPL, but may be affected by other factors unrelated to the prognosis of PD patients, as inconsistencies in collection and management of the samples. Overall, PET protein loss quantification may be a more specific marker of peritoneal large-pore dysfunction and is seemingly more convenient than 24-hour measurements. The aim of this study was to compare the results of both sampling methods. Method A total of 144 adult incident PD patients were included. A standard peritoneal equilibration test, 24-hour urine and dialysate collection, and multifrequency bioimpedance analysis were performed. Independent-samples t test and Pearson correlation coefficient were performed to evaluate relevant clinical associations. Results Statistically significant univariable relationships for 24h PPL were found for continuous ambulatory PD technique (CAPD) and, with a correlation coefficient & gt;0.20, for pulse pressure, 4-hour dialysate/plasma creatinine and extracellular water/total body water. Studying 240 min PPL, only with 4-hour dialysate/plasma creatinine, creatinine clearance and bicarbonate levels were statistically significant. In both samples there was no significant association with age, gender, type of effluent (biocompatible solutions or lactate plus bicarbonate comparing with bicarbonate), comorbidity Charlson Index, or presence of diabetes. Correlation between 240 min PPL and 24h PPL ensues, but it is not strong (p & lt;0.001; r=0.365). Conclusion The weak correlation between 24h and 240 minutes show that these two measurements should not be considered equivalent. Measurements of a 24h sample might be more close to patients’ clinical status and prognosis, despite more frequent sampling errors. PET protein loss quantification should be regarded as a marker of peritoneal large-pore dysfunction.

    Abstract: Exit-site infections (ESi) are frequent complications in peritoneal dialysis (PD) patients and their prevention and treatment are key aspects to lower peritonitis’ risk. The aim of this study was to evaluate the annual incidence rate of ESi and peritonitis in Portugal and to study possible associations between exit-site (ES) care protocols in each Portuguese unit and the number / rate of ESi and peritonitis. Method We performed a national study using two questionnaires at each Portuguese PD Unit: one about the incidence of catheter-related infections, the other characterizing patients’ education and ES care protocols. ESi and peritonitis were defined according to ISPD guidelines. Associations between variables were performed using T-student test or pairwise correlation test. STATA software was used. Results Of the 23 Portuguese PD Units, 14 units answered both questionnaires. In the last two years (2017 & 2018), those units followed 1453 patients. Portuguese ESi incidence rate was 0.41 episodes per year [1 episode per 29.2 months (MSSA incidence rate 0.13; MRSA incidence rate 0.03; Pseudomonas incidence rate 0.07)] and the peritonites incidence rate was 0.37 (1 episode per 32.5 months). We found a trend between the absolute number of ESi episodes and the number of peritonites in each unit (r=0.5, p=0.05). Although ESi prevention guidelines were known by 100% of the Portuguese units, only three out of 5 of the selected guidelines for this study were followed by 100% of the units: monitoring catheter-related infections on a yearly basis; using antibiotic prophylaxis at time of catheter placement and treating nasal carriage of S. aureus. The other 2 guidelines have variable implementation: 12 out of 14 units (86%) perform screening of nasal carriage of S. aureus and only 6 out of 14 (43%) of the units recommend daily topic antibiotic cream at the ES. We didn’t find associations between those differences and ESi incidence. Whenever S. aureus carriage is detected, 100% of the units proceed treating with mupirocine using different posology (twice or three times a day, 5 or 7 or 21 days, with/out chlorexidine). Also, the screening of nasal carriage of S. aureus is different: only pre catheter implantation (n=4); annually (n=4); semi annually (n=3); bimonthly (n=2). Oral antibiotics are prescribed after catheter placement in 4 units. We didn’t find statistical differences in ESi / peritonitis, comparing those practices. Regarding to ES care protocols, ESi rate was lower with non-occlusive dressing (0.38 vs. 0.57) immediately after catheter insertion. ESi and peritonitis rate were lower in units where bathing without ES dressing is advocated (n=9, 0.58 & 0.37 vs. 0.32 & 0.34). The use of bath sponge is associated with higher ESi rate (0.57 vs. 0.34). The use of colostomy bags in beach baths was associated with lower incidence rate of ESi compared to regular dressing or waterproof dressing (o.32 vs. 0.54). 100% of units use two different empirical antibiotics for initial ESi treatment. In the presence of chronic ESi, 3 units don’t perform shaving of external cuff and peritonitis rate is higher in those who do not apply this procedure (0.38 vs. 0.31). Conclusion in Portuguese PD units there is a wide variability in ISPD guidelines implementation and ES care protocols. We found that using non-occlusive dressing immediately after catheter insertion, removing ES dressing before shower, bathing not using a sponge and using colostomy bags at beach baths were associated with lower incidence rate of ESi. Shaving of the external cuff was associated with lower incidence rate of peritonitis. A regular national audit of PD Units is an important tool of quality improvement to clarify the best procedures for reduction of catheter-related infections in PD.

    Abstract: Longitudinal evolution of peritoneal protein loss (PPL), a reflection of hydrostatic pressure–driven leak of plasma proteins through the large‐pore pathway, is not clear. Time on PD causes loss of mesothelial cells, vasculopathy, and increased thickness of the submesothelial fibrous layer. Are these structural changes associated with progressive increase of PPL, in a parallel with the rise in the D/P creatinine? The aim of the present study was to identify longitudinal changes of PPL over time. This single‐center, longitudinal study included 52 peritoneal dialysis (PD) patients with a median follow‐up of 26.5 months, evaluated at two different time points with a minimum interval of 6 months. Repeated measures analysis was performed using paired sample t ‐test or the nonparametric Wilcoxon signed‐rank test, depending on the distribution. After a median interval of 15.5 months, lower levels of residual renal function and urine volume, lower Kt/V, and creatinine clearance were found. D/P creatinine and PPL were stable, but a decrease in ultrafiltration was present. Systemic inflammation, nutrition, and volume overload showed no significant change with time on PD. Analysis of a subpopulation with over 48 months between initial and subsequential assessment ( n = 11) showed again no difference in inflammation, nutritional and hydration parameters from baseline, but importantly PPL decreased after more than 4 years on PD (mean difference 1.2 g/24, p = 0.033). D/P creatinine and dip of sodium remained unchanged. The absence of deleterious effects of time on PD is reassuring, pointing to the benefit of updated PD prescription, including the standard use of more biocompatible solutions towards membrane preservation and adjusted prescription avoiding overhydration and inflammation while maintaining nutritional status. After controlling for confounders, PPL may act as a biomarker of acquired venous vasculopathy, even if small pore fluid transport rates and free water transport are preserved.

    Abstract: 〈 b 〉 〈 i 〉 Introduction: 〈 /i 〉 〈 /b 〉 Quantification of peritoneal protein loss (PPL) may be expressed according to a timely collection (24-h measurement or 4-h PET assessment) and as a concentration. The aim of this study was to compare the quantification methods of 24-h and 4-h collections. 〈 b 〉 〈 i 〉 Methods: 〈 /i 〉 〈 /b 〉 This study included 81 prevalent peritoneal dialysis patients. Demographics and clinical and bioelectrical impedance features were registered. PPL was measured (4-h PET and 24-h results) and peritoneal protein clearance was calculated. A linear regression model was performed. 〈 b 〉 〈 i 〉 Results: 〈 /i 〉 〈 /b 〉 Age and continuous ambulatory peritoneal dialysis (compared to cycler) were positively associated with greater PPL on 24-h collections. Neither cardiovascular disease, hypertension, diabetes nor the comorbidity Charlson Index was significantly associated with PPL. There was a consistent univariable relationship with D/P creatinine, whichever sampling method was used. Only 24-h measurements of PPL correlated with body composition variables. In multiple linear regression analysis, D/P creatinine association with PPL stands out. On the other hand, 24-h determinations (in grams or clearance) were associated with overhydration. PET protein quantification was associated with peritoneal creatinine clearance. 〈 b 〉 〈 i 〉 Discussion/Conclusion: 〈 /i 〉 〈 /b 〉 Different methods sign different pathophysiological pathways. PET protein loss quantification should be regarded as a marker of peritoneal membrane intrinsic permeability. Measurements of a 24-h sample might be closer to patients’ clinical status and prognosis, signalizing opportunities for therapy intervention.
