Trauma Registry: Trauma Quality indicators analysis in hospitalized patients.

PURPOSE: to consolidate a Trauma Register (TR) trough REDCap data acquisition platform and to validate, in this context, local Quality Indicators (QI) as improvement opportunities in trauma management. METHODS: continuous data acquisition of all patients admitted in Irmandade da Santa Casa de Misericórdia de São Paulo adult Trauma bay and it's validation in REDCap platform; 6 months retrospective cohort of QI impact in length of hospitalar stay, complications and mortality. Fisher, Chi-squared, Wilcoxon and Kruskal-Wallis tests were used to correlate QIs fails with the endpoints, considering p<0.05 and CI <95% as statically significant. RESULTS: 465 were admitted in Trauma bay, with 137 patients hospitalized (29.5%); the number of QIs compromised were related with more complications (p=0.075) and increased length of stay (p=0.028), especially the delay in open fracture's surgical management, which increased the severe complications' incidence (p=0.005). CONCLUSION: the REDCap data acquisition platform is useful as a tool for multi center TR implementation, from ethical and logistical point of view; nevertheless, the proposed QIs are validated as attention points in trauma management, allowing improvements in traumatized patients treatment.

Effect of physical exercise on immune, inflammatory, cardiometabolic biomarkers, and fatty acids of breast cancer survivors: results from the MAMA_MOVE Gaia After Treatment trial.

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.

Exercise Training Benefits Health-Related Quality of Life and Functional Capacity during Breast Cancer Chemotherapy: A Randomized Controlled Trial.

PURPOSE: To examine the effectiveness of a supervised exercise training program (SETP) on health-related quality of life (HRQoL) and functional capacity in women with breast cancer (BC) undergoing chemotherapy. METHODS: Ninety-three women with early-stage BC were randomly allocated to a SETP plus usual care (exercise, n = 47) or usual care alone (UC, n = 46). The SETP included three sessions per week, combining aerobic and resistance training, conducted concurrently over the chemotherapy. The EORTC Cancer Quality-of-Life-Questionnaire-Core-30 (QLQ-C30) and the BC-specific module (QLQ-BR23) were used to assess HRQoL. Functional capacity was analyzed by maximum voluntary handgrip strength (MVHS) and by the 30-s chair sit-to-stand test (30-s CST). These endpoints were assessed at baseline (t0); middle (t1; after 8 or 12 wk of t0); and at the end of chemotherapy (t2; after 20 wk of t0). Mean changes from baseline were assessed by an intention-to-treat approach. RESULTS: Mixed linear model analyses showed that Exercise group experienced less deterioration in several domains of QLQ-C30 at t2, including in global health status/QoL (Δ = 9.39 units; P = 0.034), QLQ-C30 summary score (Δ = 8.08 units; P < 0.001), physical (Δ = 15.14 units; P < 0.001), role ( Δ = 21.81 units; P < 0.001), cognitive (Δ = 9.16 units; P = 0.032) and social functioning (Δ = 11.67 units; P = 0.038), compared with the UC group. Similarly, Exercise group exhibited significant lower levels of fatigue (Δ = -20.19 units; P < 0.001) and appetite loss (Δ = -13.69 units; P = 0.034), compared with the UC group. Significant between-group differences were observed on MVHS of the tumor/surgery upper limb side (Δ = 2.64 kg; P < 0.001) and contralateral limb (Δ = 2.22 kg; P < 0.001), and on the 30-s CST score (Δ = 3.56repetitions; P < 0.001), favoring the Exercise group. No differences were observed on QLQ-BR23 domains. CONCLUSIONS: Exercise training was an effective complementary therapy to prevent the deterioration of HRQoL and functional capacity during chemotherapy in women with early-stage BC.

Safety of Endoscopy Units during the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic drastically changed the daily routine of all healthcare systems worldwide, and endoscopy units were no exception. Endoscopic exams were considered to have a high risk of transmission, and therefore, the safety of endoscopy units and the consequent need for pre-endoscopy SARS-CoV-2 screening were questioned early on. The aim of our study was to assess the safety of endoscopy units during the COVID-19 pandemic, as well as the effectiveness/necessity for SARS-CoV-2 screening prior to endoscopies. Material and Methods: This is a retrospective and single-center study carried out in a Portuguese tertiary hospital. All patients who underwent endoscopic procedures between September 1, 2020 and February 28, 2021 were included. The pre-endoscopy screening consisted of a specific questionnaire or a RT-PCR test for SARS-CoV-2 (nasal and oropharyngeal swab). Data were obtained through patient's clinical records and the Trace COVID platform. Results: A total of 2,166 patients were included. Patients had a mean age of 61.8 years and were predominantly male (56.2%, n = 1,218). Eighty-one (3.7%) patients had previous SARS-CoV-2 infection, with a median difference of 74 days (IQ 40.5:160.5) between infection and endoscopy. Most patients (70.2%, n = 1,521) underwent PCR screening for SARS-CoV-2 up to 72 h before the procedure, with the remaining patients (29.8%, n = 645) answering a questionnaire of symptoms and risk contacts up to 3 days before endoscopy. Of the patients who underwent RT-PCR screening for SARS-CoV-2, 21 (1.4%) tested positive, and all were asymptomatic at the time of the screening. The evaluation for SARS-CoV-2 infection up to 14 days after the endoscopic exams identified 9 positive patients (0.42%) for SARS-CoV-2. The median difference in days between endoscopy and the diagnosis of infection was 10 days. Discussion/Conclusion: Pre-endoscopy screening with RT-PCR test for SARS-CoV-2 identified a very small number of patients with COVID-19 infection as well as patients with COVID-19 infection in the following 14 days. Therefore, the risk of infection in endoscopy units is negligible if screening of symptoms and risk contacts is applied and individual protective equipment is used.

Introdução: A pandemia COVID-19 mudou drasticamente o dia-a-dia de todos os sistemas de saúde a nível mundial e as unidades de endoscopia não foram exceção. Os exames endoscópicos foram considerados exames com alto risco de transmissão pelo que desde cedo se questionou a segurança das unidades de endoscopia e a consequente necessidade de rastreio SARS-CoV-2 pré-endoscopia. O objetivo do estudo foi avaliar a segurança das unidades de endoscopia durante a pandemia por COVID-19 bem como a eficácia/necessidade de rastreio SARS-CoV-2 prévio aos exames endoscópicos. Material e métodos: Foi desenvolvido um estudo retrospetivo e unicêntrico, no qual todos os doentes submetidos a exames endoscópicos entre 1 de setembro de 2020 e 28 de fevereiro de 2021 foram incluídos. Como estratégia de rastreio pré endoscopia foram aplicados questionários específicos de sintomas e contactos de risco, ou teste PCR de SARS-CoV-2 (zaragatoa nasal e orofaríngea). Os dados clínicos foram obtidos através do processo clínico do doente e da plataforma Trace COVID-19. Resultados: Foram incluídos um total de 2,166 doentes submetidos a exames endoscópicos durante o período de estudo. Os doentes incluídos apresentaram uma média de idades de 61.8 anos e eram maioritariamente do sexo masculino (56.2%, n = 1,218). 3.7% (n = 81) dos doentes já tinha tido infeção por COVID-19 no passado, sendo a mediana da diferença de dias entre a infeção e a data do exame de 74 dias. A maioria dos doentes (70.2%, n = 1,521) foi submetido a rastreio por PCR de SARS-CoV-2 até 72 horas antes do procedimento, sendo os restantes doentes (29.8%, n = 645) submetidos a um questionário de sintomas e contactos de risco realizado até 3 dias antes do procedimento. Dos doentes que realizaram rastreio por PCR de SARS-CoV-2, 21 (1.4%) apresentaram teste positivo, estando todos assintomáticos à data do teste. Aquando da verificação de infeção por SARS-CoV-2 até 14 dias após a realização dos exames endoscópicos apurou-se que apenas 9 doentes (0.42%) testaram positivo para SARS-CoV-2, sendo a mediana da diferença de dias entre a data do exame e o diagnóstico de infeção de 10 dias. Discussão/Conclusão: O rastreio pré-endoscopia com teste PCR de SARS-CoV-2 identificou um número reduzido de doentes infetados com COVID-19 e o número de doentes com infeção por COVID-19, nos 14 dias seguintes aos exames endoscópicos, foi muito baixo. Assim, se aplicado o rastreio de sintomas e contactos de risco, usados os equipamentos de proteção individual adequados, o risco de infeção nas unidades de endoscopia torna-se negligenciável.

Infliximab Induction Strategies in Corticosteroid-Refractory Acute Severe Ulcerative Colitis: A Case Series and Literature Review.

Acute severe ulcerative colitis (ASUC) is an emergent medical condition and particularly challenging to treat efficaciously. Infliximab is one of the medical salvage treatment options after corticosteroid refractoriness, but the best induction strategy is not yet defined. With this case series, the authors intend to describe three corticosteroid-refractory ASUC cases with different intensified/accelerated infliximab induction approaches and review the literature on this topic. The first case describes an 18-year-old girl with ASUC at disease onset with rapid progression to toxic megacolon, complicated also with anemia, hypoalbuminemia, and coagulopathy. After corticosteroid failure, both accelerated and intensified (10 mg/kg) infliximab regimen was completed within 11 days, with solid clinical response and colon imaging normalization. Second, we present a 26-year-old male with left-sided ulcerative colitis known for 2 years, under mesalazine, who developed a moderate flare and was started on infliximab after partial and inconsistent response to corticosteroids. During the induction period, he presented this time an ASUC episode, which motivated an early and intensified third dose with good clinical response. Finally, we describe the case of a 78-year-old man with ulcerative proctitis for 12 years presenting ASUC with proximal disease extension as well. After unsatisfactory response to corticosteroids, infliximab was initiated on an accelerated induction regimen, completed in 13 days, with the standard dose, achieving clinical remission. Accelerated or intensified infliximab induction plans are becoming current clinical practice in corticosteroid-refractory ASUC. Current guidelines refer to the possibility of this type of strategies, not determining the optimal regimen due to lack of solid evidence. Literature is mainly based on retrospective studies, not randomized, with heterogeneous groups according to disease severity, and the effect on colectomy rates, mainly on the long term, is not clear. Additional well-supported studies are needed on this subject in order to seek a more widely uniform approach.

A agudização grave de colite ulcerosa é uma emergência médica, particularmente difícil de tratar de forma eficaz. O infliximab é uma das opções de tratamento médico de resgate após refractariedade aos corticosteróides, porém a melhor estratégia de indução ainda não está definida. Com este relato de série de casos, os autores pretendem descrever três casos de agudização grave de colite ulcerosa refratária a corticosteróides com diferentes abordagens de indução intensificada/acelerada de infliximab e rever a literatura sobre este tópico. O primeiro caso descreve uma jovem de 18 anos com agudização grave de colite ulcerosa, à apresentação da doença, com rápida progressão para megacólon tóxico, complicada também com anemia, hipoalbuminemia e coagulopatia. Após ausência de resposta a corticosteróides, foi iniciado regime acelerado e intensificado (10 mg/kg) de infliximab, concluído em 11 dias, com resposta clínica e normalização das alterações imagiológicas do cólon. Em segundo lugar, apresentamos um homem de 26 anos com colite ulcerosa esquerda conhecida há 2 anos, sob messalazina, que apresentou uma agudização moderada da doença e iniciou infliximab após resposta parcial e inconsistente aos corticosteróides. Durante o período de indução, apresentou desta vez um episódio de agudização grave, o que motivou uma terceira dose precoce e intensificada com boa resposta clínica. Por fim, descrevemos o caso de um homem de 78 anos com proctite ulcerosa há 12 anos apresentando agudização grave de colite ulcerosa, também com extensão proximal da doença. Após resposta insatisfatória a corticosteróides, foi iniciado infliximab em regime de indução acelerada, completado em 13 dias, com a dose padrão, obtendo remissão clínica. Os esquemas de indução de infliximab acelerados ou intensificados têm vindo a tornar-se prática clínica habitual nos casos de agudização grave de colite ulcerosa refratária a corticosteróides. As diretrizes atuais referem a possibilidade deste tipo de estratégias, não indicando qual o regime ideal por falta de evidência sólida. A literatura baseia-se principalmente em estudos retrospetivos, não randomizados, com heterogeneidade de grupos de estudo de acordo com a gravidade da doença e o efeito nas taxas de colectomia, sobretudo a longo prazo, não é claro. Estudos mais fundamentados são necessários sobre esta matéria de modo a que seja possível uma abordagem amplamente mais uniforme.

Effects of a Physical Exercise Program on Quality of Life and Physical Fitness of Breast Cancer Survivors: the MAMA_MOVE Gaia After Treatment Trial.

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.

Perfil de competências do enfermeiro coordenador de um serviço de urgência / What if disaster strikes..... How prepared are emergency room nurses?

A crescente procura por mais e melhores cuidados de saúde tem levado a um aumento significativo na ultima década do numero de episódios em serviço de urgência, uma situação que é transversal a todos os níveis de atuação. Do lado oposto a este aumento estão equipas reduzidas em número, com dificuldade em dar resposta perante serviços sobrelotados, na maior parte das vezes por situações pouco ou não urgentes, situação explicada por alguma ineficiência dos cuidados de saúde primários e pelo fácil acesso aos serviços hospitalares de urgência. Esta é uma situação que sobrecarrega os serviços de saúde e os profissionais, colocando em causa a segurança e a qualidade dos cuidados. Neste mesmo contexto, a gestão de cuidados ganha uma elevada importância, pelo que é imperativo entregar essa função a profissionais capazes e preparados para a mesma. Num ambiente de grande complexidade como o serviço de urgência, dinámico e com um fluxo de utentes mantido durante as 24 horas do dia, e onde o enfermeiro gestor não está em permanente presença física, é ao enfermeiro coordenador de equipa que cabe essa gestão de cuidados e até a gestão do serviço, na ausência do enfermeiro gestor do mesmo. Ainda que a figura do enfermeiro coordenador de equipa não esteja contemplada na carreira de Enfermagem, ela existe em praticamente todos os serviços de urgência. Desta forma, é imperativo definir qual o perfil de competências destes elementos, fundamentais para o bom funcionamento dos serviços e para o garante da segurança e qualidade dos cuidados de enfermagem em contexto de urgência. Neste sentido, realizamos um estudo com base na técnica de Delphi, que começou pela construção de uma proposta de perfil de competências, composta por 21 competências, agrupadas por tipologia (comportamentais, técnico-profissionais e de liderança e gestão). A elaboração deste instrumento foi suportada pela revisão bibliográfica, e posteriormente colocada sob escrutínio de um painel de peritos, conforme preconizado para a técnica de Delphi. Na primeira ronda, os peritos que integraram o painel, também contribuíram individualmente com sugestões de competências a acrescentar à proposta de perfil. A proposta final deste perfil de competências do enfermeiro coordenador de equipa, constituído por 28 competências, obteve concordância máxima em 92,9% delas (26 competências), e com um grau de consenso MUITO ELEVADO em 21 competências e ELEVADO nas restantes sete. Foi, assim, possível construir uma versão de consenso para a qual se sugere validação e que se espera servir de catalisador para a mudança de paradigma, legislando e regulamentando a figura do enfermeiro coordenador de equipa, com domínios de competências bem definidos e que permitam o desenvolvimento adequado dessas mesmas competências.

The growing demand for more and better health care has led to a significant increase in the last decade of the number of episodes in emergency services, a situation that cuts across all levels of activity On the opposite side of this growth are teams that are reduced in number, with difficulty in responding to overcrowded services, most often due to low or non-urgent situations, a situation explained by some inefficiency of primary health care services and by the easy access to hospital emergency services. This is a situation that overloads health services and professionals, putting the safety and quality of care at risk. In this context, care management gains a great importance, which is why it is imperative to deliver this task to professionals who are capable and prepared for it. In highly complex environment such as the emergency room, which is dynamic, has a flow of users 24 hours a day, and where the nurse manager is not physically present all the time, it is the nursing team coordinator who is responsible for the care management and even the management of the service. Although the figure of the nursing team coordinator is not included in the nursing career, it exists in practically all emergency services. Thus, it is imperative to define the competence profile of these elements, which are fundamental for the proper functioning of services and for guaranteeing the safety and quality of nursing care in an emergency context. Taking this into account, we carried out a study base on the Delphi technique, which began with the construction of a proposal for a competences profile, comprising 21 competences, grouped by typology (behavioral, technical-professional and leadership and management). The elaboration of this instrument was supported by the bibliographical review, and later placed under the scrutiny of a panel of experts, as recommended for the Delphi technique. In the first round, the experts who were part of the panel also contributed individually with suggestions of competences to be added to the profile's proposal. The final draft of the competences profile of the nursing team coordinator, consisting of 28 competences, obtained maximum agreement in 92.9% of them (26 competences). and with a degree of consensus VERY HIGH in 21 competences and HIGH in the remaining seven. Thus, it was possible to build a version of consensus for which validation is suggested and which is expected to serve as a catalyst for a paradigm shift, legislating and regulating the figure of the nursing team coordinator, with well-defined domains of competences that allow for the adequate development of these same skills.

Point-of-care transthoracic echocardiography: An essential management tool for acute massive pulmonary thromboembolism.

The pulmonary thromboembolism may be a life-threatening condition. A hip fracture surgery patient aged >90 years old had a sudden post-operative episode of shock, de-saturation, and reverted cardiac arrest. A point-of-care transthoracic echocardiography (TTE) undertaken by an anesthesiologist revealed inferior vena cava dilation/flattening, right cardiac chamber dilation, and McConnell signs (right ventricular apex hyperkinesia and lateral wall hypokinesia); the ventricular septal wall was shifting to the left side, and the left ventricular chamber collapsed at the end-systole, indicating a high ejection fraction in the context of obstructive shock. As such, it revealed signs of pulmonary thromboembolism. Despite the absolute contraindication for thrombolysis and therapeutic hypocoagulation, the treatment was started immediately along with vasopressor support, which was life-saving in this patient. A summary TTE played a pivotal role in our patient's case, helping with the differential diagnosis of the cause of shock.

Effects of walking football on adherence, safety, quality of life and physical fitness in patients with prostate cancer: Findings from the PROSTATA_MOVE randomized controlled trial.

Aims: To analyze the feasibility and impact of a walking football (WF) program on quality of life (QoL), cardiorespiratory fitness (CRF), muscle strength, and balance program in men with prostate cancer under androgen deprivation therapy (ADT). Methods: Fifty patients with prostate cancer (stages IIb-IVb) under ADT were randomized to a 16-week WF program plus usual care (n=25) or usual care control group (n=25). The WF program consisted of three 90-minute sessions per week. Recruitment, withdrawal, adherence, enjoyment rate, and safety of the intervention were recorded throughout the study. Cardiorespiratory fitness was assessed before and after the interventions, while handgrip strength, lower limb muscle strength, static balance, and QoL were assessed before, during (week 8), and after (week 16) the interventions. Adverse events during sessions were also recorded. Results: The WF group showed high levels of adherence (81.6 ± 15.9%) and enjoyment rate (4.5 ± 0.5 out of 5 points). In the intention-to-treat analysis, the WF group showed an improvement in chair sit-to-stand (p=0.035) compared to the control group. Within-group comparisons showed that handgrip strength in the dominant upper limb (p=0.024), maximal isometric muscle strength in the non-dominant lower limb (p=0.006), and balance in the dominant limb (p=0.009) improved over time in the WF group but not in the usual care group. The results obtained from the per-protocol analysis indicate that CRF improved significantly in the WF group as compared to the control group (p=0.035). Within-group analysis revealed that CRF (p=0.036), muscle strength in dominant (p=0.006) and non-dominant (p=0.001) lower limbs, and balance in the non-dominant lower limb (p=0.023) improved after 16 weeks of WF, but not in the control group. One major traumatic injury (muscle tear) was reported with a complete recovery before the end of the intervention. Conclusion: This study suggests that WF is feasible, safe, and enjoyable in patients with prostate cancer under hormonal therapy. Furthermore, patients who adhere to the WF program can expect cardiorespiratory fitness, muscle strength, and balance improvements.

Effects of exercise training on cardiac toxicity markers in women with breast cancer undergoing chemotherapy with anthracyclines: a randomized controlled trial.

AIMS: Exercise training has been suggested to prevent anthracycline-related cardiac dysfunction, but clinicalbased evidence is scarce. We investigated the effects of a supervised exercise training programme (SETP) on cardiac toxicity markers in women with breast cancer (BC) receiving anthracycline-containing chemotherapy. METHODS AND RESULTS: Ninety-three women with early-stage breast cancer were randomly allocated to a supervised exercise training programme (SETP) plus usual care group (Exercise, n = 47) or usual care alone group (UC, n = 46). The SETP consisted of three sessions per week, combining aerobic and resistance training, conducted concurrently across the anthracycline-containing chemotherapy length. The primary endpoint was the change in left ventricular ejection fraction (LVEF) from baseline to the end of anthracycline cycles. Secondary endpoints included global longitudinal strain (GLS) and other conventional echocardiographic parameters, cardiorespiratory fitness (estimated peak VO2), circulating biomarkers (NT-proBNP, hs-TnT), and safety of the SETP. The study endpoints were also assessed 3 months after the end of anthracycline cycles. All patients were prescribed four cycles of doxorubicin plus cyclophosphamide (AC). No significant between-group differences in LVEF change were seen at the end of AC [mean difference: 0.7%; 95% confidence interval (CI): -0.8, 2.3; P = 0.349] and 3 months after AC (1.1%; 95% CI: -0.5, 2.6; P = 0.196). Compared to the usual care (UC) group, the estimated peak VO2 increased in the Exercise group at the end of AC (1.6 mL O2·kg-1·min-1; 95% CI: 0.06, 3.1; P = 0.041) and 3 months after AC (3.1 mL O2·kg-1·min-1; 95% CI: 1.4, 4.7; P < 0.001). No between-group differences were found in the remaining secondary endpoints. No serious adverse events were observed during SETP. CONCLUSION: Exercise training was safe during chemotherapy and significantly improved cardiorespiratory fitness. No significant effects were seen on cardiac toxicity markers (LVEF or GLS) as compared to the usual care. TRIAL REGISTRATION: Mama Move Gaia on treatment trial ISRCTN32617901.

Breast cancer patients are often treated with chemotherapy. Despite the clinical benefit, some of these drugs increase the risk of cardiac toxicity and impair patients' cardiorespiratory fitness. Exercise training has been proposed as a preventive approach, but clinical-based evidence is scarce. The results of this trial showed that an exercise training programme, combining aerobic training and resistance training, conducted during chemotherapy, did not significantly attenuate the decline in conventional cardiac function parameters when compared to usual care. However, the results of this trial showed that the training programme was safe and significantly improved cardiorespiratory fitness.

Spatiotemporal bioavailability of PCDD/Fs and dl-PCBs in wild mussels from the Portuguese Atlantic coast.

This study aimed to assess the spatiotemporal bioavailability of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs) and dioxin-like polychlorinated biphenyls (dl-PCBs) in wild adult mussels, Mytilus galloprovincialis, collected along the Portuguese Atlantic coast between 2009 and 2020. The work is part of a national environmental monitoring program. The purpose was to evaluate the dioxins' temporal trends, the human and ecological risks, and the correlation between mussels' location and the main pollutant sources in Portugal. The levels and congener patterns of the most toxicity-relevant 17 PCDD/Fs and 12 dl-PCBs were determined, with the dl-PCBs dominant. The sum of Σ17PCDD/Fs and Σ12dl-PCBs values ranged from 2.0 to 4.0 ng WHO-TEQ kg-1, (wet weight basis), below the limits established by the European Commission for contamination in fish and fishery products (6.5 ng per kg-1). The study included five years - 2009, 2010, 2016, 2018 and 2020 -, allowing to verify the impact of European Directive 2013/39/UE against the pollution of water in Portugal; it was observed that dioxin levels in mussels diminished over the time. Statistical analysis allowed verification of different spatial trends of dl-PCB profiles along the Portuguese Atlantic coast. The mono-ortho dl-PCB pentachlorinated congener IUPAC #118 prevailed in 2009 and 2018 in all sampling sites, and it was predominant in 2010, 2016 and 2020, followed by the congeners IUPAC #105, #156 and #167. The IUPAC #167, #169 and #123 were the most abundant hexachlorinated congeners, and the IUPAC #77 the most abundant tetrachlorinated congener. This work emphasises the importance of monitoring dioxins and mapping the congeners in Atlantic coastal ecosystems, to contribute to their elimination.

Post-infarction ventricular septal defect surgery in Portugal.

INTRODUCTION AND OBJECTIVE: We performed a collective analysis of a dedicated national post-myocardial infarction ventricular septal defect (VSD) registry to further elucidate controversial areas of this clinical entity's surgical treatment. METHODS: A descriptive statistical analysis was carried out and cumulative survival using the Kaplan-Meier method and multivariate logistic regression of risk factors for 30-day mortality are presented. RESULTS: Median survival of the cohort (n=76) was 72 months (95% CI 4-144 months). Better cumulative survival was observed in patients who underwent VSD closure more than 10 days after myocardial infarction (log-rank p=0.036). Concomitant coronary artery bypass grafting (CABG), different closure techniques, location of the VSD, extracorporeal membrane oxygenation as bridge to closure, or intra-aortic balloon pump as bridge to closure showed no statistically significant differences at Kaplan-Meier analysis. Multivariate binary logistic regression for independent factors affecting status at 30 days showed a statistically significant effect of age (OR 1.08; 95% CI 1.01-1.15) and concomitant CABG (OR 0.23; 95% CI 0.06-0.90). CONCLUSIONS: Our results are comparable with previous reports regarding mortality, risk factors and concomitant procedures. Timing of surgery remains a controversial issue. Later closure seems to be advantageous, however, there is significant observational bias.

Endoscopic Mini-or Less-Open Sublay Operation (E/MILOS) in ventral hernia repair: a minimally invasive alternative technique.

The ideal ventral hernia surgical repair is still in discussion1. The defect closure with a mesh-based repair is the base of surgical repair, in open or minimally invasive techniques2. The open methods lead to a higher surgical site infections incidence, meanwhile, the laparoscopic IPOM (intraperitoneal onlay mesh) increases the risk of intestinal lesions, adhesions, and bowel obstruction, in addition to requiring double mesh and fixation products which increase its costs and could worsen the post-operative pain3-5. The eTEP (extended/enhanced view totally intraperitoneal) technique has also arisen as a good option for this hernia repair. To avoid the disadvantages found in classic open and laparoscopic techniques, the MILOS (Endoscopically Assisted Mini or Less Open Sublay Repair) concept, created by W. Reinpold et al. in 2009, 3 years after eTEP conceptualization, allows the usage of bigger meshes through a small skin incision and laparoscopic retro-rectus space dissection, as the 2016 modification, avoiding an intraperitoneal mesh placement6,7. This new technique has been called E-MILOS (Endoscopic Mini or Less Open Sublay Repair)8.

Fungi are crucial for soil organic carbon (SOC) formation, especially for the more persistent mineral-associated organic C (MAOC) pool. Yet, evidence for this often overlooks arbuscular mycorrhizal fungi (AMF) communities and how their composition and traits impact SOC accumulation. We grew sudangrass with AMF communities representing different traits conserved at the family level: competitors, from the Gigasporaceae family; ruderals, from the Glomeraceae family; or both families combined. We labeled sudangrass with 13 C-CO2 to assess AMF contributions to SOC, impacts on SOC priming, and fungal biomass persistence in MAOC. Single-family AMF communities decreased total SOC by 13.8%, likely due to fungal priming. Despite net SOC losses, all AMF communities contributed fungal C to soil but only the Glomeraceae community initially contributed to MAOC. After a month of decomposition, both the Glomeraceae and mixed-family communities contributed to MAOC formation. Plant phosphorus uptake, but not hyphal chemistry, was positively related to AMF soil C and MAOC accumulation. Arbuscular mycorrhizal fungi contribution to MAOC is dependent on the specific traits of the AMF community and related to phosphorus uptake. These findings provide insight into how variations in AMF community composition and traits, and thus processes like environmental filtering of AMF, may impact SOC accumulation.

Pertuzumab in Combination with Trastuzumab and Docetaxel in the Neoadjuvant Treatment for HER2-Positive Breast Cancer.

Introduction: This study aims to assess safety and effectiveness of pertuzumab in combination with trastuzumab and docetaxel in the neoadjuvant treatment (NeoT) of HER2-positive breast cancer. Methods: Two consecutive retrospective cohorts (n = 94, 2012-2015 and 2015-2017) of adult women with HER2-positive breast cancer, receiving NeoT at the breast clinic in Portugal (IPO-Porto), were followed. All patients had surgery and received trastuzumab as adjuvant therapy. The 2012-2015 cohort received doxorubicin, cyclophosphamide, docetaxel plus trastuzumab, whereas the 2015-2017 cohort was treated with the same protocol plus pertuzumab. Results: The 2012-2015 cohort was older (median 53 years), with locally advanced tumors (48.1%), mostly hormone receptor positive (59.3%). The 2015-2017 cohort was younger (median 43 years) with 60% operable tumors. Pathologic complete response (pCR) improved in the second cohort, while maintaining a good safety profile and tolerability. Clinical staging (p = 0.001) and hormone receptor (p = 0.003) were significant predictors of pCR, but not treatment regimen (p = 0.304). Conclusion: Further research with larger samples and longer follow-up is needed to understand the clinical differences. Clinical effectiveness of treatment should also be measured through overall and progression-free survival.

Arbuscular mycorrhizal fungal communities with contrasting life-history traits influence host nutrient acquisition.

Life-history traits differ substantially among arbuscular mycorrhizal (AM) fungal families, potentially affecting hyphal nutrient acquisition efficiency, host nutrition, and thereby plant health and ecosystem function. Despite these implications, AM fungal community life-history strategies and community trait diversity effects on host nutrient acquisition are poorly understood. To address this knowledge gap, we grew sudangrass with AM fungal communities representing contrasting life-history traits and diversity: either (1) five species in the AM family Gigasporaceae, representing competitor traits, (2) five Glomerales species, representing ruderal traits, or (3) a mixed-trait community combining all ten AM fungal species. After 12 weeks, we measured above and belowground plant biomass and aboveground nutrient uptake and concentration. Overall, AM fungal colonization increased host nutrition, biomass, and foliar δ5nitrogen enrichment compared to the uncolonized control. Between the single-trait communities, the Glomeraceae community generally outperformed the Gigasporaceae community in host nutrition and plant growth, increasing plant phosphorus (P) uptake 1.5 times more than the Gigasporaceae community. We saw weak evidence for a synergistic effect of the mixed community, which was only higher for plant P concentration (1.26 times higher) and root colonization (1.26 times higher) compared to the single-trait communities. However, this higher P concentration did not translate to more P uptake or the highest plant biomass for the mixed community. These findings demonstrate that the AM symbiosis is affected by community differences at high taxonomic levels and provide insight into how different AM fungal communities and their associated traits affect host nutrition for fast-growing plant species.

Vascular effects of Fragaria vesca L. in human arteries.

Fragaria vesca L. (wild strawberry) is traditionally used for its anti-inflammatory activity and for gastrointestinal, cardiovascular and urinary disorders. A previous study with the rat aorta showed that its leaves extract elicits endothelium-dependent vasorelaxation. Our aim was to investigate the clinical application of Fragaria vesca in vascular disease, by assessing the vascular effects of an infusion and hydroalcoholic extract in internal thoracic arteries from patients with coronary artery disease. The extracts elicited no effects on basal vascular tone and did not induce any vasorelaxation. At low concentration (0.02 mg/mL), the infusion potentiated the noradrenaline-induced contraction, while the other concentrations did not elicit significant changes in efficacy or potency. Differences between our findings and the previous report on rat aorta may result from methodological differences, e.g. vascular bed, method of extraction and extract composition. The clinical applicability of extracts of Fragaria vesca in patients with cardiovascular disease remains to be fully validated.

Poststroke psychosis: a case report.

BACKGROUND: Stroke is currently the second leading cause of death in the elderly population. Neuropsychiatric complications following stroke are common, can be overlooked, and are associated with low quality of life, increase in the burden of caregiving and impaired functional status. METHODS: We report a case of poststroke psychosis in a woman without prior psychiatric history. In addition, a brief, nonsystematic review of the pertinent literature was performed. RESULTS: Psychosis can present in almost 5% of stroke survivors. Many patients with poststroke psychosis have no previous psychiatric history and the most common lesion locations include the right frontal, temporal and parietal lobes, the white matter connecting those areas, as well as the right caudate nucleus. Compared to other stroke survivors, patients with poststroke psychosis are more likely to depend on assistance in their everyday lives, can have more difficulty coping with the sequelae of stroke, and have an increased 10-year mortality risk. Guidelines for diagnosing and managing poststroke psychosis are needed. CONCLUSION: Psychosis is a possible complication of stroke and is associated with impairment and increased mortality. Guidelines for diagnosing and managing poststroke psychosis are currently lacking. To assure evidence-based care, further research is needed.
