Abstract
Endovascular therapy (EVT) is a highly effective stroke treatment, but trials validating this intervention did not include patients with posterior cerebral artery (PCA) occlusion. The aim of this systematic review with meta-analysis was to assess the efficacy and safety of EVT for acute PCA occlusion. PubMed, Scopus, ISI, and CENTRAL were searched for studies assessing EVT in adult patients with PCA occlusion. Outcomes of interest were recanalization, symptomatic intracerebral haemorrhage (sICH), mortality, functional independence, and excellent functional outcome at 90 days. Frequencies and odds ratios (ORs) were pooled using random effect models and heterogeneity was measured using the I2 statistic and explored by means of meta-regression. Fifteen studies were included, all observational. Recanalization rates were high [81%, 95% CI (73-88%)] and sICH rates low [2%, 95% CI (1-4%)]. Heterogeneity was high for recanalization (I2 = 80%) but not for sICH, and not accounted for by any of the moderators tested. Compared to best medical treatment, EVT was associated with higher chances of sICH [OR = 2.04, 95% CI (1.12-3.71)] and no effect in functional independence [OR = 0.98, 95% CI (0.63-1.54)], with a tendency to higher chances of excellent functional outcome [OR = 1.29, 95% CI (0.90-1.86)] and mortality [OR = 1.56, 95% CI (0.84-2.90)]. EVT for acute PCA occlusion is technically feasible but associated with higher chance of sICH. There is no evidence to support this treatment to achieve higher rates of functional independence, but other gains that can impact patients' quality of life cannot be excluded. More studies are required with robust design, better patient selection, and comprehensive outcome evaluation.

Abstract
PURPOSE Physical exercise has positive effects on clinical outcomes of breast cancer survivors such as quality of life, fatigue, anxiety, depression, body mass index, and physical fitness. We aimed to study its impact on immune, inflammatory, cardiometabolic, and fatty acids (FA) biomarkers. METHODS An exploratory sub-analysis of the MAMA_MOVE Gaia After Treatment trial (NCT04024280, registered July 18, 2019) was performed. Blood sample collections occurred during the control phase and at eight weeks of the intervention phase. Samples were subjected to complete leukocyte counts, cytokine, and cardiometabolic marker evaluation using flow cytometry, enzyme-linked immunoassays, and gas chromatography. RESULTS Ninety-three percent of the 15 participants had body mass index ≥ 25 kg/m2. We observed a decrease of the plasmatic saturated FA C20:0 [median difference - 0.08% (p = 0.048); mean difference - 0.1 (95%CI - 0.1, - 0.0)], positively associated with younger ages. A tendency to increase the saturated FA C18:0 and the ratio of unsaturated/saturated FA and a tendency to decrease neutrophils (within the normal range) and interferon-gamma were observed. CONCLUSIONS Positive trends of physical exercise on circulating immune cells, inflammatory cytokines, and plasmatic FA were observed. Larger studies will further elucidate the implications of physical exercise on metabolism. These exploratory findings may contribute to future hypothesis-driven research and contribute to meta-analyses.

Abstract
OBJECTIVE: To explore the effects of minimal intervention of patient education (MIPE) for reducing disability and pain intensity in patients with low back pain (LBP). DESIGN: Intervention systematic review with meta-analysis of randomized controlled trials. LITERATURE SEARCH: We searched the MEDLINE, Embase, CENTRAL, CINAHL, and PsycINFO databases from inception to May 2023. STUDY SELECTION CRITERIA: Trials comparing MIPE, consisting of a single session of patient education, to no or other interventions in patients with LBP. DATA SYNTHESIS: Random effects meta-analysis was conducted where possible. A noninferiority margin of 5 points (0-100 scale) was considered for noninferiority hypotheses. We assessed risk of bias using the revised Cochrane risk-of-bias tool (RoB 2), and certainty of evidence using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework. RESULTS: A total of 21 trials were included. There were no differences between MIPE and no intervention for effects on disability and pain intensity. There was low-certainty evidence that MIPE had inferior effects on short-term disability (mean difference = 3.62; 95% CI: 0.85, 6.38; 15 trials; n = 3066; I2 = 75%) and pain intensity (mean difference = 9.43; 95% CI: 1.31, 17.56; 10 trials; n = 1394; I2 = 90%) than other interventions. No differences were found for subsequent time points. CONCLUSION: As an intervention delivered in isolation, and without tailoring (ie, one-size-fits-all intervention), MIPE on average did not provide benefits for reducing disability and pain intensity over no or other interventions. We encourage clinicians to consider using additional/other or more tailored treatments when helping people manage LBP. J Orthop Sports Phys Ther 2024;54(2):1-13.

Abstract
OBJECTIVE To investigate up-to-date evidence of the effectiveness of neural mobilisation techniques compared with any type of comparator in improving pain, function, and physical performance in people with musculoskeletal pain. DATA SOURCES The following sources were consulted: PubMed, Web of Science, CENTRAL, CINAHL, Scopus, and PEDro databases; scientific repositories; and clinical trial registers. The last search was performed on 01/06/2023. METHODS Two reviewers independently assessed the studies for inclusion. We included randomised, quasi-randomised, and crossover trials on musculoskeletal pain in which at least one group received neural mobilisation (alone or as part of multimodal interventions). Meta-analyses were performed where possible. The RoB 2 and the Grading of Recommendations Assessment, Development and Evaluation tools were used to assess risk of bias and to rate the certainty of evidence, respectively. RESULTS Thirty-nine trials were identified. There was a significant effect favouring neural mobilisation for pain and function in people with low back pain, but not for flexibility. For neck pain, there was a significant effect favouring neural mobilisation as part of multimodal interventions for pain, but not for function and range of motion. Regarding other musculoskeletal conditions, it was not possible to conclude whether neural mobilisation is effective in improving pain and function. There was very low confidence for all effect estimates. CONCLUSIONS Neural mobilisation as part of multimodal interventions appears to have a positive effect on pain for patients with low back pain and neck pain and on function in people with low back pain. For the other musculoskeletal conditions, results are inconclusive.

Abstract
AIMS Endovascular therapy (EVT) is a highly effective stroke treatment, but it requires the administration of contrast media which puts patients at risk of acute kidney injury (AKI). AKI is associated with increased morbidity and mortality in cardiovascular patients. METHODS PubMed, Scopus, ISI and the Cochrane Library were systematically searched for observational and experimental studies assessing the occurrence of AKI in adult acute stroke patients submitted to EVT. Two independent reviewers collected study data regarding study setting, period, source of data, and AKI definition and predictors, the outcomes of interest being AKI incidence and 90-day death or dependency (modified Rankin Scale score ≥3). These outcomes were pooled using random effect models, and heterogeneity was measured using the I2 statistic. RESULTS 22 studies were identified and included in the analysis, involving 32 034 patients. Pooled incidence of AKI was 7% (95% CI 5% to 10%), but heterogeneity was high across studies (I2=98%), and not accounted for by the definition of AKI used. The most frequently reported AKI predictors were impaired baseline renal function (5 studies) and diabetes (3 studies); 3 studies (2103 patients) reported data on death and 4 studies (2424 patients) reported data on dependency. Overall, AKI was associated with both outcomes, with ORs of 6.21 (95% CI 3.52 to 10.96) and 2.86 (95% CI 1.88 to 4.37), respectively. Heterogeneity was low for both analyses (I2=0%). CONCLUSIONS AKI affects 7% of acute stroke patients submitted to EVT and identifies a subgroup of patients for which treatment outcomes are suboptimal, with an increased risk of death and dependency.

Abstract
Objective We assess the impact of obstructive sleep apnea (OSA) treatment on the quality of marital relationships. Moreover, we evaluate the proportion of couples sleeping separately before treatment and whether there was any change after treatment began, which is still little explored in the literature. Methods A prospective study was conducted between April 2021 and April 2023, with users diagnosed with OSA in a level 2 hospital in Portugal. A questionnaire was applied before and after the start of treatment to both user and partner, which included questions on whether they slept together or separately, the disturbing factors of sleep quality, and satisfaction with the marital relationship. Statistical analysis was performed using R (version 4.2.2; R Development Core Team, Vienna, Austria). Results Seventy questionnaires were applied, 79% to male users. Forty-one percent of users reported that they slept at least once or twice a month separated from their spouse, and, of these, 41% always slept in separate rooms. The chief complaints of partners not sleeping together were snoring (86%), restless sleep (17%), and witnessed apnea (14%). After treatment, 72.4% started to sleep together again, with a statistically significant difference in the condition before and after intervention. Among all patients, 69% said that their personal lives had improved and, when asked the same question to their spouse, 74% recognized the benefit of therapy. Conclusion Starting treatment positively influenced the quality of the marital relationship of users and their partners, with a statistically significant proportion of couples sleeping together again.

Abstract
To assess the effects of a group class physical exercise program on health-related quality of life (HRQOL), physical fitness and activity, and safety in early breast cancer women after treatment, a double-phase trial [16-week control phase (CP) followed by a 16-week intervention phase (IP)] was designed. Outcomes were evaluated at baseline (T1), 8 (T2) and 16 (T3) weeks (CP), and 24 (T4) and 32 (T5) weeks (IP). The primary endpoint was global health status. Out of 82 enrolled patients, 37 completed the IP. Global health status decreased (-10,1; 95% CI -19.8 to -0.4; p = 0.040) during the CP and stabilized during the IP. Physical and sexual functioning increased during the IP (p = 0.008; p = 0.017), while cardiorespiratory fitness increased in the CP (p = 0.004). Upper limb strength and lower limb functionality increased during both phases [CP: p < 0.0001, p = 0.001 (surgical and nonsurgical arm), p = 0.028; IP: p < 0.0001, p = 0.002, p = 0.009]. Body mass index decreased in the IP (p = 0.026). Waist circumference increased in the CP (p = 0.001) and decreased in the IP (p = 0.010); sedentary behaviours and moderate and vigorous physical activity did not change. Adherence to 70% of the sessions was reported in 54% of patients. No serious adverse events related to the intervention were reported. In conclusion, the physical exercise program was able to prevent the decline in global health status and to improve other domains of HRQOL and physical fitness. As physical exercise is not the standard of care in many countries, the implementation of group class programs might be an option.

Abstract
This work aims to describe the observed enrichment of inverted repeats in the human genome; and to identify and describe, with detailed length profiles, the regions with significant and relevant enriched occurrence of inverted repeats. The enrichment is assessed and tested with a recently proposed measure (z-scores based measure). We simulate a genome using an order 7 Markov model trained with the data from the real genome. The simulated genome is used to establish the critical values which are used as decision thresholds to identify the regions with significant enriched concentrations. Several human genome regions are highly enriched in the occurrence of inverted repeats. This is observed in all the human chromosomes. The distribution of inverted repeat lengths varies along the genome. The majority of the regions with severely exaggerated enrichment contain mainly short length inverted repeats. There are also regions with regular peaks along the inverted repeats lengths distribution (periodic regularities) and other regions with exaggerated enrichment for long lengths (less frequent). However, adjacent regions tend to have similar distributions.

Abstract
INTRODUCTION Ischemic stroke is a major cause of death and disability. Despite major advances in reperfusion therapies, most patients don´t benefit from these treatments as the time window for such interventions is limited. Therefore, other treatment options are desirable. Edaravone has been demonstrated in previous studies to reduce neurologic deficits in stroke patients. OBJECTIVE To test the hypothesis that edaravone reduces functional dependence in ischemic stroke patients. MATERIAL AND METHODS Systematic review and meta-analysis of randomized controlled trials and observational studies comparing edaravone to placebo in adult patients with ischemic stroke. The efficacy outcomes of interest were good and excellent functional outcomes at 90 days, defined as modified Rankin Scale (mRS) scores of 0-2 and 0-1 respectively. The safety outcomes of interest were intracranial hemorrhage and mortality. RESULTS 19 studies were included. Edaravone treatment was associated with improved chances of 90-day good (OR=1.31, 95% CI 1.06-1.67) and excellent (OR=1.26, 95% CI 1.04-1.54) functional outcomes. Mortality was also lower in edaravone treated patients (OR=0.50, 95% CI 0.45-0.56). There were no differences in terms of intracranial hemorrhage. Most studies were observational and performed in Asian populations, especially Japan. Heterogeneity was high for all outcomes but reduced when analysis was restricted to randomized trials. CONCLUSION Edaravone is a promising treatment for ischemic stroke patients, with a more favorable time window. However, more randomized studies including patient populations outside Asia are required to confirm this hypothesis.

Abstract
Functional status is an important and meaningful outcome in people with chronic obstructive pulmonary disease (COPD), although its measurement is not embedded in routine clinical assessments. This study described the functional status of people with COPD using the 1-min sit-to-stand test (1minSTS) over a 6-month period and the examined sociodemographic and clinical characteristics associated with this outcome. Data from a prospective study including people with COPD were analyzed. Functional status was assessed monthly with the 1minSTS over 6 months. Linear-mixed effect models assessed the 1minSTS number of repetitions mean change. One-hundred and eight participants (82.4% men; 66.9 ± 9.5 years) were included. A significantly lower number of repetitions in the 1minSTS over the 6-month period was associated with being female (estimate: −4.69, 95%CI: −8.20; −1.18), being older (estimate: −0.56, 95%CI: −0.77; −0.34), having higher BMI (estimate: −0.55, 95%CI: −0.81; −0.28) and having higher activity-related dyspnea (estimate: −2.04, 95%CI: −3.25; −0.83). Half of the participants showed improvements above three repetitions in the 1minSTS over the 6-month period, independently of their baseline impairment (1minSTS < 70% predicted: 52.5%; ≥70% predicted: 54.4%). To conclude, monthly follow-up assessments were associated with clinically relevant benefits in the functional status of people with COPD. Age, body composition, and activity-related dyspnea were the main predictors of functional status over time. Further research is needed to corroborate our findings and to support the beneficial effects of regular COPD monitoring.

Background
Behavioral and emotional factors may trigger cardiovascular events (CVE). Watching sports when there is an emotional connection between the supporters and the supportive team, is believed to be potentially associated with CVE. However, epidemiological studies have been inconsistent, with several studies showing an increase in CVE, while others reporting a protective effect.
Purpose
To assess the effect of watching sport events on the incidence of cardiovascular events.
Methods
Pubmed, and Embase were systematically searched to identify appropriate articles. Reference lists were then hand searched for additional relevant articles. To be included, articles had to assess the association between CVE and sport events supporters (adeptos). Pooled association measures, using random effects analysis, were calculated for mortality; arrhythmias; myocardial infarction (MI). Subgroup analysis was conducted based on gender. Publication bias and between-study heterogeneity were evaluated.
Results
There were nineteen studies included in the analysis. The pooled relative risks for mortality, arrhythmias and MI were 1.45(0.98-2.15; 95%CI; I2=70%; p=0.02); 1.31(0.98-1.77; 95%CI; I2=85%; p<0.01); 1.11(0.98-1.24; 95%CI; I2=91%; p<0.01) respectively (Figure 1A). The null association persisted in the subgroup analyses by gender for mortality (Figure 1B) as well as for MI and for the combined endpoint MI/stroke (non significant relative risks).
Conclusions
Overall this analysis suggests that watching sport events does not increase cardiovascular events regardless of gender.

Abstract
Recent studies show that musculoskeletal conditions contribute significantly to years lived with disability considering the entire global population. Pain and functional disability are the main problems that people with these conditions suffer. Neural mobilization has been shown to be an effective intervention in the treatment of musculoskeletal pain within individual trials, also contributing to improved functionality. Some systematic reviews have been carried out during the last years with the aim of synthesizing the scientific evidence on the use of neural mobilization techniques in the treatment of musculoskeletal disorders. However, they varied a lot in the methodological approaches and, consequently, in the findings and conclusions. Thus, this document is a planned protocol of a comprehensive systematic review with meta-analysis that we intend to carry out to review the scientific literature regarding up-to-date evidence on the use of neural mobilization in the management of people suffering from musculoskeletal pain disorders. The study designs that we will consider as inclusion criteria will be randomized and quasi-randomized clinical trials. The target population will be adults and older adults with musculoskeletal pain. Any controlled trial using any neural mobilization technique as an intervention in one of the trial groups will be included. The main outcomes of interest will be pain, functional status, and physical performance tests (muscle strength, flexibility, and balance). There will be no restrictions on follow-up time or type of setting. The risk of bias of the included studies will be assessed by the RoB 2 tool and the certainty of the evidence will be evaluated using the comprehensive Assessment, Development and Assessment of Assessment Recommendation (GRADE) approach. We intend to present the findings through narrative descriptions and, if possible, through meta-analytic statistics. Trial registration: PROSPERO registration number. CRD42021288387.

Abstract
BACKGROUND Axial spondyloarthritis (axSpA), particularly ankylosing spondylitis was historically considered a male's disease and has been under-recognized in women. Emerging evidence reveals sex differences in pathophysiology, disease presentation and therapeutic efficacy. OBJECTIVE To identify differences between sexes in a Portuguese cohort of patients with axSpA regarding clinical manifestations, disease activity, functional capacity, patient related outcomes and presence of sacroiliitis on x-ray or magnetic resonance imaging. METHODS Patients with ≥18 years fulfilling the ASAS- Assessment of Spondyloarthritis International Society classification criteria for axSpA registered in the electronic Rheumatic Diseases Portuguese Register (Reuma.pt) were included in this multicentric cross-sectional study. Sociodemographic data, clinical features and imaging were collected from the first record in Reuma.pt. These variables were compared between sexes using Mann-Whitney test and Chi-Square test. Variables with a significant association with variable sex were considered in the multiple variable analysis to adjust the sex effect on the outcome variables. Statistical analysis was performed with R version 4.0.2 and p <0.05 was considered statistically significant. RESULTS A total of 1995 patients were included, 1114 (55.9%) men and 881 (44.1%) women. Men had an earlier disease onset (25.1 vs 28.4, p <0.001), were younger at diagnosis (26.9 vs 30.4, p<0.001) and were more frequently smokers (32.1% vs 15.7%, p <0.001). Comparing to women, men had worse Bath Ankylosing Spondylitis Metrological Index scores (4.0 vs 3.4, p<0.001), higher levels of C-Reactive Protein (10.5 vs 6.9 mg/L, p <0.001) and were more often Human Leukocyte Antigen-B27 positive (67.8% vs 54%, p <0.001). In contrast, women more frequently had inflammatory bowel disease (8.8% vs 4.9%, p =0.004), higher levels of erythrocyte sedimentation rate (25.0 vs 21.0mm/h, p=0.003) and worse patient-related outcomes- Bath Ankylosing Spondylitis Disease Activity Index (5.7 vs 4.5, p<0.001), Patient Global Assessment (60.0 vs 50.0, p <0.001) and fatigue (6.2 vs 5.0, p <0.001). DISCUSSION In this large multicentric study from a Portuguese axSpA cohort, we confirmed sex differences in patients with axSpA. This work brings awareness to these differences, resulting in less underdiagnosis and misdiagnosis, optimizing treatment strategies, and improving outcomes in axSpA.

Abstract
Family support has been identified as an important factor for the psychological adjustment of patients with chronic physical conditions. This study aimed to systematically review and conduct a meta-analysis of studies comparing the effectiveness of family-based versus patient-oriented interventions for chronic physical conditions. The search was performed between April 12 and April 29, 2021, on Web of Science (all databases included), Scopus, PsycINFO, and CENTRAL. Thirteen RCTs were included. The results favored family-based interventions for various patient outcomes related to pain, distress, self-efficacy, social and emotional function, coping, the welfare of the domestic environment, capacity to mobilize social support, and sexual relationships with medium to large effect sizes (Cohen's d range: 0.45-0.90). This type of intervention also decreased family members' anxiety, depression, sleep problems, and distress, improving search and presence of meaning in life, social support, the support provided to the patient, and sexual relationships with medium to very large effect sizes (Cohen's d range: 0.58-2.76). The meta-analytical findings suggested that the patients' (k = 12, d = 0.34; 95% CI = 0.13-0.55, I2 = 74%, p < 0.01) and family members' (k = 4, d = 0.68; 95% CI = 0.08-1.27, I2 = 88%, p < 0.01) psychosocial outcomes significantly improved with family-based interventions compared with patient-oriented interventions. The meta-analysis of patients' self-efficacy showed a medium-size effect (d = 0.64; k = 3; I2 = 19%). The results suggest a trend toward the beneficial effects of family-based interventions, but more research is needed with higher quality RCTs to confirm this hypothesis.

Abstract
Fundamento: Enquanto a angiografia coronária invasiva é considerada padrão outro para o diagnóstico da doença arterial coronariana (DAC), envolvendo os vasos coronários epicárdicos, a revascularização coronariana guiada por fisiologia representa uma prática padrão ouro contemporânea para a administração invasiva de pacientes com DAC intermediária. Porém, os resultados de longo prazo da avaliação da gravidade da estenose por meio da fisiologia, em comparação à angiografia como guia para a cirurgia de bypass – enxerto de bypass de artéria coronária (CABG), ainda são incertos. Esta metanálise visa avaliar os resultados clínicos de um CABG guiado por fisiologia em comparação a um CABG guiado pela angiografia. Objetivos: Buscamos determinar se os resultados entre um CABG guiado por fisiologia e os de um CABG guiado por angiografia são diferentes entre si. Métodos: Pesquisamos nas bases Medline, EMBASE e Cochrane Library. A última data de busca foi junho de 2020, e todos os estudos anteriores foram incluídos. Realizamos uma metanálise de razão de risco agrupado para quatro principais resultados: morte por todas as causas, infarto do miocárdio (IM), revascularização do vaso alvo (TVR) e eventos cardiovasculares adversos maiores (MACE). Valor de p <0,05 foi considerado estatisticamente significante. A heterogeneidade foi avaliada com o teste Q de Cochran, e quantificada pelo índice I2. Resultados: Identificamos cinco estudos incluindo um total de 1.114 pacientes. Uma metanálise agrupada não demonstrou diferenças significativas entre a estratégia da fisiologia e da angiografia para IM (razão de risco [RR] = 0,72; IC95%, 0,39–1,33; I2 = 0%; p = 0,65), TVR (RR = 1,25; IC95% = 0,73–2,13; I2 = 0%; p = 0,52), ou MACE (RR = 0,81; IC95% = 0,62–1,07; I2 = 0%; p = 1). A estratégia da fisiologia apresentou 0,63 vezes o risco de morte por todas as causas em comparação à estratégia da angiografia (RR = 0,63; IC95% = 0,42–0,96; I2 = 0%; p = 0,55). Conclusão: Esta metanálise demonstrou uma redução nas mortes por todas as causas quando usada a estratégia do CABG guiado por fisiologia. Porém, o curto período de acompanhamento, o tamanho da amostra pequeno dos estudos incluídos e a não-discriminação das causas de morte podem justificar essas conclusões. Estudos com períodos mais longos de acompanhamento são necessários para tirar conclusões mais robustas e definitivas.

Abstract
Background
Elderly cancer patients have a high risk of exposure to potential drug-drug interactions (pDDIs), given the therapeutic complexity to which they are subjected. The study of pDDIs is very important to enable more effective treatments, with the least possible number of complications.The aim of this study was to identify and characterize pDDIs in elderly cancer patients treated at the Day Hospital of IPO-Porto.
Methods
Information about patients sociodemographic data and chronic medication were collected through an interview with application of a questionnaire to the elderly patient. Patient’s clinical files were also consulted to complement information needed for the study. The ATC classification of drugs was performed and Micromedex® tool was used to identify and characterize pDDIs. The most prevalent pDDIs were analyzed and discussed.
Results
A total of 335 elderly patients with cancer were enrolled in the study. The prevalence of polymedication was 88.10% and excessive polymedication was 46.60%. A total of 1125 pDDIs were identified in 248 patients (74.03%) and 211 pDDIs involved at least one antineoplastic drug. The pDDIs that were detected more frequently were: Fluorouracil - Leucovorin Calcium (N = 28), Cyclophosphamide - Ondansetron (N = 27) and Metoclopramide - Tramadol (N = 20). A significant association was detected between the number of drugs consumed and the number of pDDIs.
Conclusions
Elderly patients with cancer have a high risk of drug interactions, given the polymedication they are exposed. It's crucial to implement measures to monitor their therapy in order to reduce the potential for drug interactions and improve the quality of patient's life.

Abstract
BACKGROUND Pulmonary aspiration is one of the most important complications in anesthesiology. Assessment of gastric content by ultrasound is a good method to quantify gastric volume and to determine the risk of intraoperative pulmonary aspiration. The aim of this study is to determine the accuracy of the gastric ultrasonography in the qualitative analysis of gastric content, mainly in the analysis of small amounts of liquid content. METHODS Gastric ultrasound was performed to 36 patients before upper gastrointestinal endoscopy (UGI), making two longitudinal scans at the epigastric level, one in supine position and the other in right lateral decubitus position, measuring two diameters and the area of the gastric antrum and assessing the content characteristics determining whether it was an empty stomach or contained fluid or solid content. Subsequently, the ultrasound findings were compared with UGI findings. RESULTS Gastric areas were analyzed by the trace and the lengths of the craniocaudal and anteroposterior axes concluding that there are no significant differences between the two methods. No statistically significant difference was found between UGI and US assessment technics. No statistically significant difference was found between the estimated volume by UGI and US. CONCLUSIONS Though our study has some limitations, qualitative analysis of gastric content using ultrasound followed by endoscopy enabled the conclusion that there are no differences in the qualitative assessment regarding these two techniques, supporting the important role of point-of-care gastric ultrasound (POCGUS) in the assessment of pulmonary aspiration risk by the anesthesiologist in the perioperative period.

Abstract
OBJECTIVE The purpose of this study was to systematically review the association between handgrip strength (HGS) and mortality, morbidity, and health-related quality of life (HRQL) in individuals with chronic obstructive pulmonary disease (COPD). METHODS The following databases were used: CENTRAL, CINAHL, EMBASE, MEDLINE Ovid, SPORTDiscus, and PsycINFO. Studies published between 2000 and 2020 in English, Portuguese, or French that examined the association of HGS with mortality, morbidity, and HRQL in individuals with stable COPD were selected. Two authors independently extracted data and assessed the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework. The study effects were pooled using random effects meta-analysis models after assessing heterogeneity. The search generated 710 studies, and 18 were included in the review. Studies evaluated a total of 12,046 individuals with stable COPD (mean percent of the predicted forced expiratory volume in 1 second = 34%-80%) using over 10 diverse protocols for HGS measurement. Statistically significant, small, and negative relationships were found between HGS and mortality (r = -0.03; 95% CI = -0.05 to -0.02). Independent of the outcome measure used to assess morbidity, the estimate of the overall relationship was small to moderate and negative: Body Mass Index, Airflow Obstruction, Dyspnea, and Exercise Index Updated (r = -0.42; 95% CI = -0.61 to -0.03); exacerbations (r = -0.02; 95% CI = -0.04 to -0.00); and hospitalizations (r = -0.69; 95% CI = -1.70 to 0.32). Similarly, for HRQL, independent of the outcome measure, the estimate of the overall relationship was small to fair and negative: COPD Assessment Test (weighted r = -0.22; 95% CI = -0.32 to -0.12), Chronic Respiratory Disease Questionnaire domains (-0.24 < r < -0.14), EuroQol Five-Dimension Questionnaire (utility score) (r = -0.17; 95% CI = -0.26 to -0.07), EuroQol Five-Dimension Questionnaire domains (-0.32 < r < -0.06), and St George Respiratory Questionnaire total (r = -0.26; 95% CI = -0.33 to -0.17). The quality of the evidence ranged from low to very low across outcomes. CONCLUSION Although heterogeneity was present among HGS measurement protocols, small to moderate associations were found, indicating that those with lower HGS have an increased likelihood of death, a higher risk of increased COPD morbidity (as assessed with Body Mass Index, Airflow Obstruction, Dyspnea and Exercise Capacity indexes), and poorer HRQL.

Abstract
Background:Historically, axial spondyloarthritis (particularly ankylosing spondylitis) was considered a men’s disease and has been under-recognized in women.Emerging evidence reveals gender differences in patophysiology, disease presentation and therapeutic efficacy.Objectives:To determine if there are differences between genders in a Portuguese cohort of patients with axSpA as regards clinical manifestations, disease activity, functional capacity, patient related outcomes and radiographic findings.Methods:Patients with ≥18 years fulfilling the ASAS- Assessment of Spondyloarthritis International Society classification criteria for axSpA and registered in the electronic national database- Reuma.pt were included in a multicentric cross-sectional study. Sociodemographic data, clinical features and radiographic findings were collected from the first record in Reuma.pt. These variables were compared between genders using Mann-Whitney test and Chi-Square test. Variables with a significant association with group variable (gender) were considered in the multiple variable analysis to adjust the gender effect on the outcome variables.Results:A total of 1995 patients were included, 1114 (55.9%) men and 881 (44.1%) women. Men had a lower median age at onset of disease (25.1 vs 28.4, p=0.000) and median age at diagnosis (26.9 vs 30.4, p=0.000) and were more frequently smokers (32.1% vs 15.7%, p=0.000). Comparing to women, men had worse BASMI scores (4.0 vs 3.4, p=0.000), higher levels of CPR (10.5 vs 6.9, p=0.000) and were more often HLA-B27 positive (67.8% vs 54%, p=0.000). In univariable analysis, sacroiliitis on radiograph or/and MRI (95.5% vs 91.7%, p=0.04) was more common in men, however that wasn’t confirmed in multivariable analysis.In contrast, women more frequently had more inflammatory bowel disease (8.8% vs 4.9%, p=0,004), higher levels of ESR (25.0 vs 21.0, p=0.003) and worse PROs- BASDAI (5.7 vs 4.5, p=0.000), PGA (60.0 vs 55.0, p=0.000) and fatigue (6.2 vs 5.4, p=0,000).Conclusion:Physicians must be aware of differences between genders in axial spondyloarthritis because this can result in less underdiagnosis and misdiagnosis, allow optimization of treatment strategies, and decrease overall disease burden in women with axSpA patients.References:[1]Rusman T, van Vollenhoven RF, van der Horst-Bruinsma IE.

Abstract
Despite continuous advances in burn care, sepsis is still the main cause of death in burn patients. Procalcitonin (PCT) has been reported as an accurate sepsis biomarker and also as a fair predictor of death. The aim of this study was to assess PCT kinetics in the first week postburn regarding sepsis diagnosis and death prognosis. Sample included 142 patients with ≥15% TBSA, admitted from January 2011 to December 2014 at Coimbra Burns Unit, Portugal. Sepsis diagnosis was done according to American Burn Association criteria. PCT range and median values in the first 7 days after burns were statistically analyzed for its potential for sepsis diagnosis and death prognosis. A subanalysis was done regarding TBSA, sex, age, and inhalation injury. First week PCT range and median were significant for sepsis diagnosis and death prognosis, but the median area under the curve was greater in the last case. TBSA influenced PCT accuracy, which was greater for TBSA less than 40% either for diagnosis or prognosis. Age was inversely related to the accuracy, being better in younger than 40 years in both cases. PCT diagnostic accuracy was not affected by sex, opposing to the prognostic one which is better in women. Inhalation injury had no effect on diagnostic accuracy, but it happens with prognostic accuracy. PCT levels' variation is related to sepsis evolution and outcome. Its median performs better than its range. Always coupled with clinical examination, monitoring PCT levels kinetics may help early sepsis detection, potentially reducing morbidity and mortality, being also useful for death prognosis.

Abstract
Introduction Antipsychotic drugs are the cornerstone of the pharmacological treatment of psychotic disorders; however, even with Second-generation antipsychotics (SGA), adverse effects continue to be extremely accentuated and the treatment effectiveness is compromised by low adherence of the patient. Objectives Taking into consideration the importance of adverse effects for psychotic therapeutics, this study aims to analyze the adverse effect of the Neuroleptic Malignant Syndrome (NMS) reported in EudraVigilance Database, associated with 3 widely used SGA, Risperidone, Quetiapine, and Clozapine. Methods The EudraVigilance Database was analyzed from 09/01/2017 to 31/10/2020 about NMS, associated with Risperidone, Quetiapine, and Clozapine. NMS is the second most reported adverse effect inside the Nervous System Disorders SOC (System Organ Class). There were just considered NMS as suspected adverse effect. Results It was observed a general tendency of reduction of NMS reports from 2017 to 2020 (most of them performed by healthcare professionals). Risperidone presented the highest level of reports during this period (more than 350), followed by Quetiapine and Clozapine. The NMS reports were predominantly referred to the male sex, from 18 to 64 years old. Risperidone presented the lowest number of fatal cases of NMS (1), in contrast with 3 reported with Quetiapine and Clozapine. A significant number of patients with Schizophrenia recovered from NMS. Conclusions It is important to do clinical monitoring of the NMS, because it is rare, although it has life-threatening consequences. Pharmacovigilance databases are important tools to evaluate the safety of drugs and it must be more widely and efficiently promoted for healthcare and patients use.

Abstract
INTRODUCTION AND HYPOTHESIS Knowledge about the impact of pelvic floor surgery on sexual function is limited and inconsistent. A prospective study assessed the impact of surgery for prolapse (POP) or stress urinary incontinence (SUI) on sexual function and determined the biopsychosocial predictors for changes in sexual function after surgery. MATERIALS AND METHODS Sexually active women scheduled for correction of POP and/or SUI were recruited over a 6-month period. Consenting participants were asked to complete the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) to evaluate sexual function. The King's Health Questionnaire and Prolapse Quality-of-Life Questionnaire were used to assess UI and POP symptoms and their impact on quality of life (QoL), respectively. Women were reviewed over a period of 1 year post-surgery. RESULTS Ninety-one patients were followed up over 1 year. After stratification into only or both SUI and POP surgery, global sexual function improved significantly in each group (p < 0.001). The improvement in the overall QoL score after pelvic surgery showed a significant correlation with the improvement in global sexual function (SUI group: r = - 0.38, p < 0.01; POP group: r = - 0.44, p < 0.05). For women undergoing SUI surgery, only educational level and prior hysterectomy had a significant association with improved sexual function. For women undergoing POP surgery with or without SUI surgical repair, no sociodemographic characteristics were preditive of improvement of sexual function. CONCLUSIONS Significantly improved sexual function was observed 1 year after pelvic floor surgery, and the improvement was predicted by other social and physical factors in addition to normal functional anatomy.

Abstract
Introduction Since the declaration of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic in March 2020, Portugal was considered a role model with regards to the first COVID-19 wave. However, a third wave started in 2021 started, turning the country into the worst in the world regarding new infections and death rate per capita in the last weeks of January 2021. No significant data regarding the country's first wave of hospitalized patients have been published. Those data may help understand the differences over time regarding patients and the clinical approach to them. Herein, we present data of COVID-19 patients hospitalized at the main tertiary hospital of the second-most affected county at the time and identify risk factors associated with disease progression and outcomes. Materials and methods We performed a prospective observational study of patients admitted with COVID-19 to a central hospital between March 20 and June 1, 2020. The primary endpoint of this study was 30-day mortality or the need for ventilatory support and the secondary outcomes were both outcomes individually. Results 245 patients were included, with a median age of 79 years, 52% males. Hypertension (n = 172) and dyslipidemia (n = 114) were the most frequent comorbidities. Half of the patients (n = 121) were treated with hydroxychloroquine. The primary outcome occurred in 114 patients; mortality at 30 days was 35%. Age (OR 1.05; 1.02-1.07) and active cancer (OR 3.89; 1.43-10.57) were associated with the primary outcome, with dyslipidemia being protective (OR 0.46; 0.25-0.80). Treatment with hydroxychloroquine or lopinavir/ritonavir was not associated with the main outcome. Patients who had been symptomatic for more than 7 days had lower mortality (OR 0.23; 0.09-0.63). Discussion In the present study, age and cancer were associated with higher mortality, as noted in prior articles. The population had a higher median age than reported in previous studies, which may explain the increased mortality. The protective association of dyslipidemia was not previously described. This association was not related to statin intake. Conclusion The reported high mortality of COVID-19 is rarely seen in other infectious diseases. Our elderly population probably reflects more reliably the incidence of COVID-19 in European countries with constricted age pyramids.

Abstract
OBJECTIVES This umbrella review aimed to understand the clinical benefits and adverse events associated with different modalities of intradialytic exercise in patients with end-stage renal disease undergoing hemodialysis. DATA SOURCES The search was performed until September 10th, 2020 on Scopus, Web of Science, the Cochrane Database, CINAHL, and PubMed. METHODS This umbrella review was conducted following the PRISMA guideline statement. The methodological quality of the reviews was assessed with the AMSTAR-2. Standardized mean differences with 95% confidence intervals were estimated. The I-squared statistic was used to assess heterogeneity and the Eggers' test was performed to test asymmetry/small-study effects. RESULTS Eleven reviews were included and 48 unique meta-analyses were examined. Nine were supported by suggestive evidence (P < 0.05, small heterogeneity, absence of small-study effects, and excess significance bias). Clinical benefits were found for functional capacity associated with aerobic exercise (d = 0.81; k = 6), resistance training (d = 0.58; k = 6), neuromuscular electrical stimulation (d = 0.70; k = 5), and inspiratory muscle training (d = 1.13; k = 2), measured by the distance covered in the 6-minutes walking test. This outcome was also associated with aerobic exercise (d = 0.28; k = 7) and combined exercise, measured by VO2peak (d = 1.01; k = 5) and by the duration of the cardiopulmonary test (d = 1.07; k = 4). Isometric quadriceps muscle strength improved with neuromuscular electrical stimulation (d = 1.19; k = 7) while patients' perception of vitality improved with combined exercise (d = 0.60; k = 3). CONCLUSIONS Suggestive evidence was found for the associations between various modalities of intradialytic exercise and functional capacity. Combined exercise was associated with improvements in physical and psychosocial variables. Few or no adverse events were reported.

Abstract
BACKGROUND Estrogen receptors alpha (ERα) and beta (ERβ) and the cooperating protein GATA-binding factor 3 (GATA3) have been implicated in bladder carcinogenesis and tumour progression. GATA3 and ER have been functionally linked in the establishment of luminal fate in breast tissue, but to date their relationship in bladder cancer has not been established. This information will be useful to advance diagnostic and prognostic markers. AIM To determine the relationship between the expression of ERα, ERβ and GATA3 in bladder cancer, disclose their prognostic and diagnostic value and their association with clinicopathological characteristics. METHODS A comprehensive literature search in PubMed database was performed for all immunohistochemical studies of ERα, ERβ and/or GATA3 in bladder cancer patients. We selected eligible studies in accordance with the PRISMA guidelines and evaluated methodological quality and risk of bias based on quality criteria from the reporting recommendations for tumour MARKer (REMARK) prognostic studies. Risk of bias assessment was performed using Review Manager 5. R software was used for all statistical analysis, the packages used were meta and dmetar for the standard meta-analysis, and netmeta for the network meta-analysis. RESULTS Thirteen studies were eligible for ERα, 5 for ERβ and 58 for GATA3 meta-analysis. Low grade tumours showed significantly lower ERα expression. GATA3 was widely expressed in bladder tumours, especially urothelial carcinomas, with higher expression of GATA3 in low grade and low stage tumours. Data was insufficient to determine the prognostic value of either ERα or ERβ, but GATA3-positivity was associated with higher recurrence free survival. A negative correlation between ERα or ERβ positivity and GATA3 expression was disclosed. Additionally, several sources of heterogeneity were identified, which can be used to improve future studies. CONCLUSION The clinicopathological value of ERα and ERβ was inconclusive due to low availability of studies using validated antibodies. Still, this meta-analysis supports GATA3 as good prognostic marker. On the contrary, ERα-positivity was associated to higher grade tumours; while ERα and ERβ were inversely correlated with GATA3 expression. Considering that it has previously been shown that bladder cancer cell lines have functional ERs, this suggests that ERα could be activated in less differentiated cells and independently of GATA3. Therefore, a comprehensive analysis of ERα and ERβ expression in BlaCa supported by complete patient clinical history is required for the identification of BlaCa subtypes and subgroups of patients expressing ERα, to investigate if they could benefit from treatment with hormonal therapy.

Abstract
This systematic review aimed to systematise the different designs used to deliver pulmonary rehabilitation during acute exacerbations of COPD (AECOPD) and explore which ones are the most effective. PubMed, Scopus, Web of Science, EBSCO and Cochrane were searched. Randomised controlled trials comparing pulmonary rehabilitation or at least one of its components with usual care or comparing different components of pulmonary rehabilitation were included. Network meta-analysis was conducted in MetaXL 5.3 using a generalised pairwise modelling framework. Pooled effects compared each treatment to usual care. 42 studies were included. Most studies were conducted in an inpatient setting (57%) and started the intervention 24-48 h after hospital admission (24%). Exercise training (71%), education and psychosocial support (57%) and breathing techniques (55%) were the most used components. Studies combining exercise with breathing techniques presented the larger effects on exercise capacity (weighted mean difference (WMD) -41.06, 95% CI -131.70-49.58) and health-related quality of life (WMD 16.07, 95% CI 10.29-21.84), and breathing techniques presented the larger effects on dyspnoea (WMD 1.90, 95% CI 0.53-3.27) and length of hospitalisation (effect size =0.15, 95% CI -0.28-0.57). A few minor adverse events were found.Pulmonary rehabilitation is a safe intervention during AECOPD. Exercise, breathing techniques, and education and psychosocial support seem to be the core components for implementing pulmonary rehabilitation during AECOPD. Studies may now focus on comparisons of optimal timings to start the intervention, total duration of the intervention, duration and frequency of sessions, and intensity for exercise prescription.

Abstract
BACKGROUND Women of advanced maternal age, defined as ≥ 35 years at delivery, are at increased risk of multiple complications during pregnancy, with perinatal death being one of the most feared. For instance, the risk of stillbirth at term in this subgroup of women is higher than in younger women, and particularly high beyond 39 weeks of gestation. Induction of labor at 39-40 weeks might help prevent some cases of perinatal death, however, the fact that induction of labor has been historically associated with an increased risk of cesarean delivery and the knowledge that advanced maternal age is an independent risk factor for cesarean delivery are some of the major reasons why clinicians are reluctant to offer elective induction of labor in this particular group. OBJECTIVE The aim of the study was to assess if induction of labor in advanced maternal age was associated with increased rates of cesarean delivery when compared to expectant management. MATERIAL AND METHODS We performed an electronic search limited to published articles available between January 2000 and March 2020. Randomized clinical trials and retrospective studies with large cohorts comparing induction of labor with expectant management in singleton pregnancies at term, of women aged ≥ 35 years were included. The primary outcome was the rate of cesarean delivery in induction of labor versus expectant management, and secondary outcomes were the occurrence of assisted vaginal delivery and postpartum hemorrhage. RESULTS Eight studies, including 81151 pregnancies (26,631 in the induction group and 54,520 expectantly managed), were included in the analysis. Six of the included studies were randomized clinical trials with the remaining two being observational and retrospective cohort studies. Induction of labor was not associated with a significant increased risk of cesarean delivery (OR 0.97, 95 % CI 0.86-1.1), assisted vaginal delivery (OR 1.12, 95 % CI 0.96-1.32) or postpartum hemorrhage (OR 1.11, 95 % CI 0.88-1.41). DISCUSSION The belief that induction of labor is associated with an increased risk of cesarean delivery is based on the results of retrospective studies comparing induction with spontaneous labor at the same gestational age. However, at any point in a pregnancy, the comparison should be between induction of labor and expectant management, with the latter contributing to a pregnancy of greater gestation age and not always leading to spontaneous labor. When comparing induction to expectant management, our study shows no significant increase of cesarean section, assisted vaginal delivery or postpartum hemorrhage. Our study was not powered to assess neonatal outcomes, and additional research is needed to confirm whether induction of labor might have a positive effect in preventing stillbirth. CONCLUSION Induction of labor at term in advanced maternal age has no significant impact on cesarean delivery rates, assisted vaginal delivery or postpartum hemorrhage, giving additional reassurance to obstetricians who would consider this intervention in this particular subgroup.

Abstract
Estrogen-like metabolites have been identified in S. haematobium, the helminth parasite that causes urogenital schistosomiasis (UGS) and in patients´ blood and urine during UGS. Estrogen receptor (ER) activation is enriched in the luminal molecular subtype bladder cancer (BlaCa). To date, the significance of ER to these diseases remains elusive. We evaluated ERα and ERβ expression in UGS-related BlaCa (n = 27), UGS-related non-malignant lesions (n = 35), and noninfected BlaCa (n = 80). We investigated the potential of ERα to recognize S. haematobium-derived metabolites by docking and molecular dynamics simulations and studied ERα modulation in vitro using 3 BlaCa cell lines, T24, 5637 and HT1376. ERα was expressed in tumor and stromal cells in approximately 20% noninfected cases and in 30% of UGS-related BlaCa, predominantly in the epithelial cells. Overall, ERα expression was associated with features of tumor aggressiveness such as high proliferation and p53 positive expression. ERα expression correlated with presence of schistosome eggs. ERβ was widely expressed in both cohorts but weaker in UGS-related cases. molecular dynamics simulations of the 4 most abundant S. haematobium-derived metabolites revealed that smaller metabolites have comparable affinity for the ERα active state than 17β-estradiol, while the larger metabolites present higher affinity. Our in vitro findings suggested that ERα activation promotes proliferation in ERα expressing BlaCa cells and that this can be reverted with anti-estrogenic therapy. In summary, we report differential ER expression between UGS-related BlaCa and noninfected BlaCa and provide evidence supporting a role of active ERα during UGS and UGS-induced carcinogenesis.

Abstract
BACKGROUND Cardiotoxicity is a known complication and one of the most adverse effects from the use of conventional treatments such as anthracyclines and trastuzumab in breast cancer (BC) care. This phenomenon has been associated with the restriction of therapeutic options and the increase of cardiovascular complications, which may compromise the survival of patients. Implementation of preventive strategies is an important approach for the management of this issue. Physical exercise has been proposed as a non-pharmacological strategy to counteracting cardiotoxicity. The aim of this protocol is to describe the rationale and methods for a systematic review of published randomized controlled trials (RCTs) that have analysed the effects of physical exercise on outcomes of cardiac (dys)function in women with BC undergoing neoadjuvant or adjuvant treatment containing anthracyclines and/or trastuzumab. METHODS AND ANALYSIS This is a protocol for a systematic review reported according to the PRISMA-P 2015 checklist. Randomized controlled trials (RCTs) will be included. The literature will be screened on MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, ISI Web of Science and Scopus. The risk of bias of the included RCTs will be assessed using the Cochrane Collaboration's tool. The primary outcomes will be systolic function (left ventricular ejection fraction), diastolic function (E/A' ratio, deceleration time of early left ventricular filling, isovolumetric relaxation time, E/E' septal and lateral ratio) and myocardial deformation imaging outcomes (strain and strain rate [measured in longitudinal, radial, or circumferential directions]). Secondary outcomes will be cardiac biomarkers (troponin I or T, high-sensitivity troponin I or T, brain natriuretic peptide, amino terminal of B-type natriuretic peptide). Data will be descriptively reported, and quantitative synthesis will also be considered if the included studies are sufficiently homogenous. DISCUSSION This systematic review will help to understand the effectiveness of physical exercise on counteracting cardiotoxicity related to anticancer therapies in women with BC.

Abstract
INTRODUCTION Statins are widely prescribed drugs with established efficacy in primary and secondary prevention of cardiovascular events. Although they are mostly well tolerated, several authors have been emphasizing that the statins' safety profile is not totally clarified especially when considering risk of cancer in patients with long-term exposure to statins. This meta-analysis was aimed at evaluating the risk of cancer in patients with prolonged exposure to statins. METHODS Medline, Cochrane library, and clinicaltrials.gov were searched in order to identify studies with a minimum average follow-up of 10 years of exposure to statins and a cancer-related outcome reported. Relative risk (RR) of the primary outcomes and the combined effect was presented using a random-effects model. In the selected randomized control trials (RCT), statin exposure was compared with placebo, and in the selected observational studies, it was compared with no exposure to statins. RESULTS We retrieved 1627 studies, of which 15 full-papers were included for final review, five RCT, two cohort studies (CSs), and eight case-control studies (CCs), representing a total of 358 544 patients. Five RCT, two cohort studies (CSs), and eight case-control studies (CCs). No significant differences were found regarding risk of cancer occurrence (RR = 1.08, 0.96-1.21) or cancer mortality (RR = 0.91, 0.80-1.04) due to long-term statin exposure. Regarding all-cause mortality, a protective effect was found (RR = 0.93, 0.90-0.97). CONCLUSIONS According to available and published evidence, statins are not associated with an increased risk of cancer after prolonged exposure. These findings strengthen the role of statins in the primary and secondary prevention of cardiovascular events.

Abstract
Neospora caninum is one of the main infectious agents that cause reproductive disorders in cattle. However, knowledge about the prevalence and causal factors of bovine neosporosis is needed in order to establish control measures. The purpose of this study was to estimate the pooled prevalence and determine the risk factors of bovine neosporosis using meta-analytic methods. Searches for data on N. caninum seroprevalence and potential risk factors were conducted in the PubMed, LILACS, and SciElo databases. The random effects model was used for the meta-analysis of the included studies. The pooled prevalence of N. caninum in cattle was 24% (95% confidence interval (CI), 19-29) in North and Central America, 24% (95% CI, 20-28) in South America, 18% (95% CI, 14-21) in Asia, 15% (95% CI, 12-18) in Europe, 13% (95% CI, 11-16) in Africa, and 8% (95% CI, 4-14) in Oceania. A significant correlation was found between N. caninum infection and abortion in cows (odds ratio (OR) = 2.66, 95% CI, 1.97-3.59). The following risk factors were signicantly associated with N. caninum seroprevalence: presence of dogs on the farm (OR = 2.84; 95% CI, 1.40-5.80) and the type of cattle production system, with dairy cattle being more susceptible to bovine neosporosis (OR = 1.60; 95% CI, 1.16-2.19) than beef cattle. The adoption of measures to prevent the dissemination of N. caninum in cattle herds is suggested, aiming to reduce the economic losses incurred to the dairy and beef industry.

Abstract
Finding DNA sites with high potential for the formation of hairpin/cruciform structures is an important task. Previous works studied the distances between adjacent reversed complement words (symmetric word pairs) and also for non-adjacent words. It was observed that for some words a few distances were favoured (peaks) and that in some distributions there was strong peak regularity. The present work extends previous studies, by improving the detection and characterization of peak regularities in the symmetric word pairs distance distributions of the human genome. This work also analyzes the location of the sequences that originate the observed strong peak periodicity in the distance distribution. The results obtained in this work may indicate genomic sites with potential for the formation of hairpin/cruciform structures.

Abstract
Purpose Acute exacerbations of COPD (AECOPD) are associated with pulmonary/systemic changes; however, quantification of those changes during AECOPD managed on an outpatient basis and factors influencing recovery are lacking. This study aimed to characterize patients’ changes during AECOPD and identify factors influencing their recovery. Methods Body mass index, the modified British Medical Research Council questionnaire, number of exacerbations in the previous year, and the Charlson comorbidity index (independent variables) were collected within 24–48 hours of hospital presentation (T0). Peripheral oxygen saturation (SpO2), forced expiratory volume in one second, percentage predicted (FEV1% predicted), maximum inspiratory pressure, quadriceps muscle strength, 5 times sit-to-stand, and COPD assessment test (CAT) (dependent variables) were collected at T0 and approximately at days 8 (T1), 15 (T2), and 45 (T3) after T0. Results A total of 44 outpatients with AECOPD (31♂; 68.2±9.1 years; 51.1±20.3 FEV1% predicted) were enrolled. All variables improved overtime (P<0.05); however, at day 8, only SpO2 and CAT (P≤0.001) showed significant improvements. Changes in FEV1% predicted and SpO2 were not influenced by any independent measure, while changes in other outcome measures were influenced by at least one of the independent measures. Independently of the time of data collection, being underweight or overweight and having increased dyspnea, previous exacerbations, and severe comorbidities negatively affected patients’ outcomes. Conclusion FEV1% predicted and SpO2 were not influenced by any independent measure and, thus, seem to be robust measures to follow-up outpatients with AECOPD. No single indicator was able to predict patients’ recovery for all measures; thus, a comprehensive assessment at the onset of the AECOPD is required to personalize interventions.

Abstract
Background There are limited data on the prognosis of deferral of lesion treatment in
patients with acute coronary syndrome (ACS) based on fractional flow reserve
(FFR). Objectives To provide a systematic review of the current evidence on the prognosis of
deferred lesions in ACS patients compared with deferred lesions in non-ACS
patients, on the basis of FFR. Methods We searched Medline, EMBASE, and the Cochrane Library for studies published
between January 2000 and September 2017 that compared prognosis of deferred
revascularization of lesions on the basis of FFR in ACS patients compared
with non-ACS patients. We conducted a pooled relative risk meta-analysis of
four primary outcomes: mortality, cardiovascular (CV) mortality, myocardial
infarction (MI) and target-vessel revascularization (TVR). Results We identified 7 studies that included a total of 5,107 patients. A pooled
meta-analysis showed no significant difference in mortality (relative risk
[RR] = 1.44; 95% CI, 0.9-2.4), CV mortality (RR = 1.29; 95% CI = 0.4-4.3)
and TVR (RR = 1.46; 95% CI = 0.9-2.3) after deferral of revascularization
based on FFR between ACS and non-ACS patients. Such deferral was associated
with significant additional risk of MI (RR = 1.83; 95% CI = 1.4-2.4) in ACS
patients. Conclusion The prognostic value of FFR in ACS setting is not as good as in stable
patients. The results demonstrate an increased risk of MI but not of
mortality, CV mortality, and TVR in ACS patients.

Abstract
BACKGROUND Early sepsis diagnosis is crucial for the correct management of burn patients, and it clearly influences outcomes. The systemic inflammatory response triggered by burns mimics sepsis presentation and complicates early sepsis diagnosis. Biomarkers were advocated to aid the diagnosis of early sepsis. Serum procalcitonin (PCT) exhibits fair accuracy and good correlation with sepsis severity, being used in diverse clinical settings. However, few studies have evaluated perioperative changes in PCT levels in burn patients. The present study evaluated PCT kinetics during the first days after burn injury and subsequent surgical interventions to assess PCT utility in distinguishing septic from non-septic inflammatory responses. METHODS This study was a retrospective observational study of all burn patients admitted to the Coimbra Burns Unit (Portugal) between January 2011 and December 2014 who presented with a total burn surface area ≥ 15% and who underwent subsequent surgery. PCT kinetics were investigated a) during the first five days after burn injury and b) preoperatively during the five days after surgery in three subsets of patients, including those with no preoperative and no postoperative sepsis (NN), no preoperative but postoperative sepsis (NS), and preoperative and postoperative sepsis (SS). A total of 145 patients met the selection criteria and were included in the analysis. RESULTS PCT levels in the first five days after burn injury were significantly higher in patients who developed at least one sepsis episode (n = 85) compared with patients who did not develop sepsis (n = 60). PCT values > 1.00 ng/mL were clearly associated with sepsis. Study participants (n = 145) underwent a total of 283 surgical interventions. Their distribution by preoperative/postoperative sepsis status was 142 (50.2%) in NN; 62 (21.9%) in NS; and 79 (27.9%) in SS. PCT values exhibited a parallel course in the three groups that peaked on the second postoperative day and returned to preoperative levels on the third day or later. The lowest PCT values were found in NN, and the highest values were observed in SS; the NS values were intermediate. CONCLUSIONS PCT kinetics coupled with a clinical examination may be helpful for sepsis diagnosis during the first days after burn injury and burn surgery.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterium that colonizes and infects various host species and has been found in the poultry production chain, raising concerns about possible transmission from farm to fork. The objective of this study was to use meta-analytical methods to estimate the pooled prevalence of MRSA in chickens, turkeys, chicken meat, and turkey meat. Three electronic databases (PubMed, LILACS, and SciELO) were searched to establish MRSA prevalence from 51 studies published from 2003 through May 2017. The heterogeneity was assessed, and the pooled MRSA prevalence was calculated by using the random effects model according to the method of DerSimonian and Laird. Pooled MRSA prevalence (95% confidence interval [CI]) in turkeys, turkey meat, broilers, and chicken meat was 36% (1 to 78%), 13% (1 to 28%), 5% (2 to 9%), and 5% (3 to 8%), respectively. South America had the highest MRSA prevalence (27%; 95% CI, 17 to 37%), and North America had the lowest (1%; 95% CI, 0 to 2%). Livestock-associated MRSA has been isolated from poultry and poultry meat, indicating that this variant can spread from farm to fork. The presence of MRSA in poultry and poultry meat poses risks to public health, and steps should be taken to mitigate the contamination and spread of this bacterium along the poultry production chain.

Abstract
Background Due to greater infection susceptibility, sepsis is the main cause of death in burn patients. Quick diagnosis and patient stratification, early and appropriated antimicrobial therapy, and focus control are crucial for patients' survival. On the other hand, superfluous extension of therapy is associated with adverse events and arousal of microbial resistance. The use of biomarkers, necessarily coupled with close clinical examination, may predict outcomes, stratifying patients who need more intensive care, and monitor the efficacy of antimicrobial therapy, allowing faster de-escalation or stop, reducing the development of resistance and possibly the financial burden, without increasing mortality. The aim of this work is to check the suitability of procalcitonin (PCT) to fulfill these goals in a large sample of septic burn patients. Methods One hundred and one patients, with 15% or more of total body surface area (TBSA) burned, admitted from January 2011 to December 2014 at Coimbra Burns Unit (CBU), in Portugal were included in the sample. All patients had a diagnosis of sepsis, according to the American Burn Association (ABA) criteria. The sample was factored by survival (68 survivors and 33 non-survivors). The maximum value of PCT in each day was used for statistical analysis. Data were summarized by location measures (mean, median, minimum, maximum, quartiles) and dispersion measures (standard error and range measures). Statistical analysis was performed with SPSS© 23.0 IBM© for Windows©. Results There were statistically significant differences between PCT levels of patients from the survivor and non-survivor groups during the first and the last weeks of hospitalization as well as during the first week after sepsis suspicion, being slightly higher during this period. During the first 7 days of antimicrobial therapy, PCT was always higher in the non-survivor, still without reaching statistical significance, but when the analysis was extended till the 15th day, PCT increased significantly, rapidly, and steadily, denouncing therapy failure. Conclusion Despite being not an ideal biomarker, PCT proved to have good prognostic power in septic burn patients, paralleling the evolution of the infectious process and reflecting the efficacy of antimicrobial therapy, and the inclusion of its serial dosing may be advised to reinforce antimicrobial stewardship programs at burn units; meanwhile, more accurate approaches are not available.

Abstract
In this work, we study reverse complementary genomic word pairs in the human DNA, by comparing both the distance distribution and the frequency of a word to those of its reverse complement. Several measures of dissimilarity between distance distributions are considered, and it is found that the peak dissimilarity works best in this setting. We report the existence of reverse complementary word pairs with very dissimilar distance distributions, as well as word pairs with very similar distance distributions even when both distributions are irregular and contain strong peaks. The association between distribution dissimilarity and frequency discrepancy is also explored, and it is speculated that symmetric pairs combining low and high values of each measure may uncover features of interest. Taken together, our results suggest that some asymmetries in the human genome go far beyond Chargaff's rules. This study uses both the complete human genome and its repeat-masked version.

Abstract
Summary
Objectives:
Gene sequence features such as codon bias, codon context, and codon expansion (e.g. tri-nucleotide repeats) can be better understood at the genomic scale level by combining statistical methodologies with advanced computer algorithms and data visualization through sophisticated graphical interfaces. This paper presents the ANACONDA system, a bioinformatics application for gene primary structure analysis.
Methods:
Codon usage tables using absolute metrics and software for multivariate analysis of codon and amino acid usage are available in public databases. However, they do not provide easy computational and statistical tools to carry out detailed gene primary structure analysis on a genomic scale. We propose the usage of several statistical methods – contingency table analysis, residual analysis, multivariate analysis (cluster analysis) – to analyze the codon bias under various aspects (degree of association, contexts and clustering).
Results:
The developed solution is a software application that provides a user-guided analysis of codon sequences considering several contexts and codon usage on a genomic scale. The utilization of this tool in our molecular biology laboratory is focused on particular genomes, especially those from Saccharomyces cerevisiae, Candida albicansand Escherichia coli. In order to illustrate the applicability and output layouts of the software these species are herein used as examples.
Conclusions:
The statistical tools incorporated in the system are allowing to obtain global views of important sequence features. It is expected that the results obtained will permit identification of general rules that govern codon context and codon usage in any genome. Additionally, identification of genes containing expanded codons that arise as a consequence of erroneous DNA replication events will permit uncovering new genes associated with human disease.

Abstract
OBJECTIVES Vancomycin is the primary treatment for methicillin-resistant Staphylococcus aureus (MRSA). However, an increasing proportion of MRSA isolates with high minimum inhibitory concentrations (MICs) within the susceptible range (vancomycin 'MIC creep') is being observed. The aim of this study was to assess the vancomycin MIC distribution for S. aureus isolates over a period of 4 years in Centro Hospitalar Baixo Vouga (Aveiro, Portugal) and to identify differences in vancomycin MIC determined by different susceptibility testing methods. METHODS For each S. aureus isolate, the vancomycin MIC was assayed by the VITEK®2 automated system and the broth microdilution testing method. RESULTS The results showed significant differences in vancomycin MIC by different methods (P=0.021, sign test) and did not suggest the presence of vancomycin MIC creep during the study period. CONCLUSIONS Vancomycin MIC creep is a regional problem, therefore it can only be assessed through the evaluation of local susceptibility profiles, and antibiogram based on real MIC assay should be an essential element in local MRSA infection clinical management.
