Context: Premature ventricular contractions (PVCs) originating in the right ventricular outflow tract (RVOT) are traditionally considered idiopathic and benign. Echocardiographic conventional measurements are typically normal. Aims: To assess whether right ventricle longitudinal strain, determined by two-dimensional speckle tracking echocardiography, differ between RVOT PVCs patients (treated with catheter ablation) and healthy controls. Methods: We retrospectively selected patients with PVCs from the RVOT who underwent electrophysiological study and catheter ablation between 2016 and 2019. Patients with documented structural heart disease were excluded. Transthoracic echocardiography was performed and right ventricle global longitudinal strain (RV-GLS), free wall longitudinal strain (RVFW-LS) and left ventricle global longitudinal strain (LV-GLS) were determined as well as conventional ultrasound measurements of RV and LV function. Results: We studied 21 patients with RVOT PVCs and 13 controls. Patients with PVCs from the RVOT had lower values of RV-GLS and RVFW-LS compared with the control group (−19.4% versus −22.5%, P = 0.015 and −22.1% versus −25.5, P = 0.041, respectively). They also had lower values of LV-GLS, although still within the normal range (−19.1% versus −20.9%, P = 0.047). Regarding RVOT PVCs patients only, RV-GLS and RVFW-LS had no correlation with the PVCs burden prior to catheter ablation and they did not differ between the patients in whom the catheter ablation was successful and those in whom it was not. RV-GLS also had a positive correlation with RVOT proximal diameter (r = 0.487, P = 0.025). Conclusions: In this group of RVOT PVCs patients, we found worse RV longitudinal strain values (and therefore sub-clinical myocardial dysfunction) when compared to healthy controls.

The measures implemented to combat the COVID-19 pandemic led populations to confinement at home, with increased risk of domestic violence due to extended shared time between victims and offenders. Evidence on domestic violence in times of pandemic is lacking. This study examines the occurrence of domestic violence, associated factors and help seeking during the COVID-19 pandemic. An online survey was conducted in Portugal between April and October 2020 by NOVA National School of Public Health. The survey was disseminated through partner networks, media, and institutions working within the scope of violence. Data were collected on the experience of domestic violence, and help seeking during the pandemic. In a total of 1,062 respondents, 146 (13.7%) reported having suffered domestic violence during the pandemic, including psychological (13.0%, n = 138), sexual (1.0%, n = 11), and physical (0.9%, n = 10) abuse. Overall, the lower the age, the more the reported domestic violence. Also, a higher proportion of participants who perceived difficulties to make ends meet during the pandemic reported domestic violence. Differences between women and men and across educational levels on reported domestic violence were not statistically significant. Bivariate logistic analyses showed that, among women, reported domestic violence was more likely among those with up to secondary education compared to higher education. Most of the victims did not seek help (62.3%), the main reasons being considering it unnecessary, that help would not change anything, and feeling embarrassed about what had happened. Only 4.3% of the victims sought police help. The most common reasons for not coming forward to form a complaint were considering the abuse was not severe and believing the police would not do anything. Our findings indicate that domestic violence during the COVID-19 pandemic was experienced by both sexes and across different age groups. There is a need for investing in specific support systems for victims of domestic violence to be applied to pandemic contexts, especially targeting those in more vulnerable situations and potentially underserved.

Background and purpose: Cone Beam Computed Tomography (CBCT) is routinely used in radiotherapy to identify the position of the target volume. The aim of this study was to determine whether the CBCT dose, when followed by the treatment, influences the therapeutic outcomes as determined by in-vitro clonogenic cell survival in a radiobiological experiment. Materials and methods: Human cell lines, four cancer and one normal, were exposed to a 6 MV photon beam, produced by a linear accelerator. For half of each sample, a prior imaging dose was delivered using the on-board CBCT. A sample size of n = 103 was used to achieve statistical power. Results: The experimental group of cell lines exposed to CBCT imaging prior to treatment exhibited a reduction in mean cancer cell survival of ~17 times (p = 0.02) greater than predicted from the average dose response and equivalent to more than 5% of the therapeutic dose, compared to 11 times greater than predicted for normal cells (n.s.). Conclusion: The greater than predicted reduction in survival resulting from the additional CBCT dose is consistent with radiation-induced bystander effects.

Background and AimsThe wavefront propagation velocity in the myocardium with fibrosis is characterized by the presence of deceleration zones and late activated zones, that are absent in the normal myocardium. Our aim was to study the right ventricular outflow tract (RVOT) endocardial activation duration in sinus rhythm, and assess the presence of deceleration zones, in patients with premature ventricular contractions (PVCs) and in controls.MethodsWe studied 29 patients with idiopathic PVCs from the outflow tract, subjected to catheter ablation that had an activation and voltage map of the RVOT in sinus rhythm. A control group of 15 patients without PVCs that underwent ablation of supraventricular arrhythmias was also studied. RVOT endocardial activation duration and number of 10 ms isochrones across the RVOT were assessed. Propagation speed was calculated at the zone with the higher number of isochrones per cm radius. Deceleration zones were defined as zones with >3 isochrones within 1 cm radius. Low voltage areas were defined as areas with local electrogram with amplitude

Almond is highly produced in the NE of Portugal, where late frosts during flowering, low precipitation, and high tempera- ture in summer affect productivity and quality. Despite the use of late-flowering cultivars, plant biostimulants (PBs) and boron-based fertilizers can also be used to improve cell division, vegetative growth, photoassimilates rate, and nutritional status. PBs are widely used in some food crops, but the evaluation of their effects is still scarce. We treated three-year- old almond trees of cv. ‘Vairo,’ growing in a rainfed orchard in the NE of Portugal, with four individual treatments: two PBs (based on seaweed extract and free amino acids) and two boron-based fertilizers (applied on soil and leaves). Three monthly applications of seaweed extract (AN), free amino acids (AA), and boron ethanolamine (BE) were made. A single application of boron on the soil (BS) was made. Leaf samples were collected in treated and untreated (control) trees in cytogenetic and molecular analyses through the summer of 2019. The mitotic cell cycle analysis was performed to prepare mesophyll dividing cells stained with silver nitrate, and the molecular stability was assessed with five marker systems. This work aimed to extrapolate which individual treatment conferred higher mitotic cell cycle regularity and molecular stability. The cytogenetic and molecular data achieved in the cv. ‘Vairo,’ under the edaphoclimatic conditions studied, revealed that the individual treatments AA, BE, or BS induced higher leaf mitotic indexes, regular mitosis, and molecular stability, which might increase the photosynthetic area and production.

ResumoA fratura isolada de Tillaux representa uma rara e frequentemente mal diagnosticada fratura de tíbia distal anterolateral em adultos. Normalmente ocorre em adolescentes que se aproximam da maturidade esquelética por avulsão do ligamento tibiofibular anteroinferior. Este estudo de revisão de literatura baseada em caso tem como objetivo lembrar a existência dessa identidade em adultos, resumir seu mecanismo de lesão, diagnóstico e procedimentos de tratamento. De acordo com a literatura, este é apenas o oitavo caso descrito: uma mulher de 46 anos sofreu uma fratura isolada de Tillaux com 4 mm de deslocamento e realizaram-se redução e fixação aberta com parafuso canulado duplo. Após a reabilitação adequada, alcançou-se um excelente desfecho funcional e radiológico. É importante reconhecer e tratar adequadamente essas lesões distintas para evitar maiores instabilidades, alterações degenerativas e limitação da função articular do tornozelo. Um diagnóstico precoce e a osteossíntese apropriada desempenham um papel significativo em um prognóstico de recuperação bem-sucedido.

- Abstract
Introduction: Most of avoidable defibrillator therapies can be reduced by evidence-based programming, but defining tachycardia configurations across all device manufacturers is not straightforward. Aims: To determine if a uniform programming of tachycardia zones, independently of the manufacturer, result in a lower rate of avoidable shocks in primary-prevention heart failure (HF) patients and also if programming high-rate or delayed therapies can have some benefit. Methods: Prospective cohort with historical controls. HF patients with a primary-prevention indication for a defibrillator were randomized to receive one of two new programming configurations (high-rate or delayed therapies). A historical cohort of patients with conventional programming was analyzed for comparison. The primary endpoint was any therapy [shock or anti-tachycardia pacing (ATP)] delivered. Secondary endpoints were appropriate shocks, appropriate ATP, appropriate therapies, inappropriate shocks, syncope and death. Results: 89 patients were assigned for new programming group [high rate (n=47) or delayed therapy (n=42)]. They were compared with 94 historical patients with conventional programming. During a mean follow-up of 20±7 months, the new programming was associated with a reduction in any therapy (HR = 0.265, 95% CI 0.121-0.577, p=0.001), even after adjustment. Aproppriate ATP and any shock were also reduced. Syncope did not occur. Sudden, cardiovascular and all-cause deaths were not different between the groups. In the new programming group, neither highrate nor delayed programming were better than the other. Conclusions: In our study, programming tachycardia zones homogeneously across all manufacturers was possible and resulted in a lower rate of therapies, shocks and appropriate ATP.

Microalgae have a lot of potential as a source of several compounds of interest to various industries. However, developing a sustainable and efficient harvesting process on a large scale is still a major challenge. This is particularly a problem when the production of low-value products is intended. Chemical flocculation, followed by sedimentation, is seen as an alternative method to improve the energetic and economic balance of the harvesting step. In this study, inorganic (aluminum sulfate, ferric sulfate, ferric chloride) and organic (Zetag 8185, chitosan, Tanfloc SG) flocculants were tested to harvest Chlorella vulgaris in batch mode. Preliminary assays were conducted to determine the minimum dosages of each flocculant that generates primary flocs at different pH. Except for chitosan, the organic flocculants required small dosages to initiate floc formation. Additional studies were performed for the flocculants with a better performance in the preliminary assays. Zetag 8185 had the best results, reaching 98.8% and 97.9% efficiencies with dosages of 50 and 100 mg L−1, respectively. Lastly, a 24 full factorial design experiment was performed to determine the effects of the flocculant dosage, settling time, and mixing time on the Zetag 8185 harvesting efficiency. The harvesting efficiency of C. vulgaris was optimal at a dosage of 100 mg L−1 and 3 min of rapid mixing.

Highlights • Primary breast lymphoma (PBL) is a rare disease accounting for 0.04–0.5% of all breast malignancies. • The clinical and imaging findings in breast lymphoma can mimic those of breast carcinoma. • Sometimes, PBL presentation is suggestive of Inflammatory breast cancer. • Diagnosis depends on adequate tissue sampling for histology examination and immunophenotyping. • The therapeutic management of PBL is controversial and is not clearly established, but many studies support that it is not a surgical disease and can be treated successfully with combined chemotherapy and radiotherapy. • Imaging is a useful method to monitor a patient’s response to therapy., Introduction Primary breast lymphoma (PBL) is a rare disease accounting for 0.04–0.5% of all breast malignancies. Presentation of case This article reports a clinical case of a 81-year-old woman with a history of right breast erythema and edema associated to breast pain, with over two weeks duration. Physical examination demonstrated mammary asymmetry and inflammatory signs with orange peel skin. She had the right upper limb swollen and palpable axillar and supraclavicular lymph nodes. The principal suspicion was an inflammatory breast cancer. Imaging was unspecific. Core needle biopsy of an axillary lymph node and of the breast mass identified morphological and immunophenotypic features consistent with diagnosis of primary non-Hodgkin DLBCL. Patient was guided by Hematology. Discussion The clinical and imaging findings in breast lymphoma can mimic those of breast carcinoma. Sometimes, PBL presentation is suggestive of Inflammatory breast cancer. Diagnosis depends on adequate tissue sampling for histology examination and immunophenotyping. The therapeutic management of PBL is controversial and is not clearly established, but many studies support that it is not a surgical disease and can be treated successfully with combined chemotherapy and radiotherapy. Conclusion Breast lymphoma must be considered in the differential diagnosis of a breast lump, even in the presence of cutaneous inflammatory changes. PBL can be treated successfully with combined therapy.

- Abstract
Background. This study was conducted to assess the variation in prescription practices for systemic antimicrobial agents used for prophylaxis among pediatric patients hospitalized in 41 countries worldwide. Methods. Using the standardized Antibiotic Resistance and Prescribing in European Children Point Prevalence Survey protocol, a cross-sectional point-prevalence survey was conducted at 226 pediatric hospitals in 41 countries from October 1 to November 30, 2012. Results. Overall, 17 693 pediatric patients were surveyed and 36.7% of them received antibiotics (n = 6499). Of 6818 inpatient children, 2242 (32.9%) received at least 1 antimicrobial for prophylactic use. Of 11 899 prescriptions for antimicrobials, 3400 (28.6%) were provided for prophylactic use. Prophylaxis for medical diseases was the indication in 73.4% of cases (2495 of 3400), whereas 26.6% of prescriptions were for surgical diseases (905 of 3400). In approximately half the cases (48.7% [1656 of 3400]), a combination of 2 or more antimicrobials was prescribed. The use of broad-spectrum antibiotics (BSAs), which included tetracyclines, macrolides, lincosamides, and sulfonamides/trimethoprim, was high (51.8% [1761 of 3400]). Broad-spectrum antibiotic use for medical prophylaxis was more common in Asia (risk ratio [RR], 1.322; 95% confidence interval [CI], 1.202-1.653) and more restricted in Australia (RR, 0.619; 95% CI, 0.521-0.736). Prescription of BSA for surgical prophylaxis also varied according to United Nations region. Finally, a high percentage of surgical patients (79.7% [721 of 905]) received their prophylaxis for longer than 1 day. Conclusions. A high proportion of hospitalized children received prophylactic BSAs. This represents a clear target for quality improvement. Collectively speaking, it is critical to reduce total prophylactic prescribing, BSA use, and prolonged prescription.

Evidence on domestic violence in times of pandemic is lacking. This study examines the occurrence of domestic violence, associated factors and help seeking during the COVID-19 pandemic. An online survey was conducted in Portugal between April and October 2020 by NOVA National School of Public Health.
