Introduction: Organized mammographic screening led to an increase in the diagnosis of DCIS. In countries with adequate mammographic coverage, the percentage of DCIS reaches 20%. In Brazi, most of the states only perform occasional mammographic screening, and data about DCIS incidence is scarce. Objectives: Analyze and describe clinical, diagnostic, imaging and therapeutic characteristics of patients diagnosed with DCIS and treated at Pérola Byington Hospital (PBH), Brazil. Methods: The official database of PBH from January 2011 to December 2019 showed 11,373 cases of breast cancer, and 812 (7.4%) of them were DCIS. We analyzed retrospectively the medical record of 332 patients who underwent biopsy, vaccum assisted biopsy guided by mammography or ultrasound whose diagnosis was DCIS, and they were treated at the hospital. Patients with previous breast cancer or lobular neoplasia were excluded. We divided the analysis into two groups, based on the type of surgery they underwent, conservative or radical surgery. Some patients have been submitted to the sentinel lymph node biopsy (SLNB) at surgery and the blue technique stained by H&E (hematoxylin and eosin) was used. Results: Most patients underwent conservative surgical treatment (73.5%), with a SLNB in 34.5%. Mastectomy was performed in 26.5% of cases and in this group 93.2% there was also axillary surgery. None of the sentinel nodes was involved. In the conservative surgery group, the mammographic alterations were the main cause for the diagnosis in 80.3% of the cases, with calcifications being the most common alteration in 73.9% of the cases, followed by the palpable lesion in 18.5% of them. Mammography was also the main diagnostic test in the group of patients who underwent mastectomy (73.9%) and calcifications appeared in 67% of cases, followed by palpable lesions in 28.1%. When assessing local recurrence, a percentage of 6.4% was found in conservative surgery (ten in situ and five invasive) and 4.5% in mastectomy (one in situ and four invasive). Conclusions: The 7.4% incidence of DCIS shows that even though lower than in countries that have organized screening, it is a growing demand, especially for the public health system where stereotactic biopsy is not available in many centers. Despite the fact that most of the cases were non palpable, we found that mastectomy was indicated in 23.5% of them, probably because of the extension and multicentricity of the DCIS. The absence of metastases in SNB made us rethink the real need for its indication.

Introduction: The broad acceptance of sentinel lymph node biopsy (SLNB) led to an analysis for finding out the anatomopathological characteristics that can help predict the involvement of other axillary lymph nodes (LN) in positive sentinel lymph node (SLN) cases. Currently, it is very appropriate to investigate the cases that enable the omission of complete axillary dissection (CAD), even considering the involvement of the SLN. Some important studies on this theme were published, e.g., ACOSOG Z0011, and AMAROS. However, their results were not accepted uniformly enough because of methodological inconsistencies. Objectives: We aimed at providing a complementary basis for a pragmatic analysis of CAD after a positive SLNB in breast cancer. Methods: This is a cross-sectional study. Clinical and anatomopathological data were collected in patients with early-infiltrating breast cancer that were treated with SLNB, followed by CAD. Statistical analyses were performed using binary logistic regression and multiple logistic regression. Results: Out of 129 patients evaluated, compromise of non-sentinel additional lymph nodes was observed in 47 (36.4%) patients. According to an univariate analysis, the parameters related to non-SLN compromise were the tumor size in anatomopathological exam, histological grade III, the presence of peritumoral vascular embolism in focal area, compromise of more than one SLN, LN compromise rate of 100%, the presence of extracapsular neoplastic extension, perilymphnodal vascular involvement, perilymphatic fat compromise, and twenty or more dissected non-SNLs. The variables that increased the chance of compromise of non-SNL in the multivariate analysis were presented in following table with an accuracy of 81% (Figure). Conclusions: The tumor size on a clinical examination of the T2 category, the presence of two or more neoplastic foci in the SNL, and the size of the metastasis > 4.0 mm are the parameters that favor complete axillary lymphadenectomy.

Introduction: Over the last few decades, neoadjuvant chemotherapy (NCT) has played an increasing role in the management of breast cancer. It allows for an evaluation of the tumour reponse in vivo and may afford a de-escalation of surgeries. Despite advances in neoadjuvant treatment, evidence shows that rates of breast-conserving surgeries (BCT) after NCT are low (51%–68%) even when a patient is eligible for a less agressive surgery. Objectives: To analyze the surgical treatment performed in patients who underwent NCT in clinical stages (CS) II or III within a public health service in Brazil. Methods: A cross-sectional study was conducted with statistical analysis of the database of a public hospital in São Paulo with 11,073 patients treated from January 2009 to December 2020. Results: A total of 11,073 patients with breast cancer were treated in this period and 9,526 surgeries were performed, from which 4,613 (48.4%) were BCS and 4,913 (51.6%) were mastectomies. Among these procedures, 2,231 patients underwent NCT before surgical treatment, 275 (12%) were submitted to BCS and 1,956 (88%) to mastectomy. When compared by clinical stages: 641 were in CS II, BCS was performed in 143 (22.3%) and mastectomy in 498 (77.7%), and 1,590 were in CS III, from which 132 (8.3%) were submitted to BCS and 1,458 (91.7%) to mastectomy after neoadjuvant treatment. Conclusions: We observed that the rate of BCS after NCT in patients in CS II or III in our service was even lower than that found in the international literature. Some of the factors that may have influenced this result are: patient preference, anatomical extension of the tumor with skin ulceration (T4b), physician insecurity in performing a less aggressive treatment or difficulty accessing radiotherapy for patients from distant cities. This suggests that the potential surgical benefits of NCT are not being fully understood or explored. There is a need to resolve the uncertainties that are are holding back surgical teams from adopting more conservative surgeries.

Introduction: Hereditary Multiple Exostosis (HME) is a disorder of the bone metaphysis, transmitted in an autosomal dominant manner, which is genetically heterogeneous and has incomplete penetration in females, characterized by the presence of multiple exostoses (osteochondromas). It can lead to anatomical and functional impairments for the patient that will remain throughout his life, requiring periodic screening of the lesions to identify and treat them early. Although it can be asymptomatic, a wide spectrum of clinical manifestations are found in pediatric patients with this disorder; the therapeutic approach is substantially surgical, while the clinic is still on an experimental level. The questionable pathophysiological aspects of HME remain a subject of study and controversy in the conduct of therapy and treatment. The diagnosis requires regular screening of the lesions through imaging tests, as well as clinical findings such as: pain, which is the main surgical indication; limitation of movement (for example, forearm rotation may be limited by exostoses between the radius and ulna or maximum knee flexion may be limited by exostosis in the popliteal region) and growth disorders. In this work, we will present a case of osteochondroma in rib with invasion of the left breast in a patient with HME, while emphasizing the role of mastology to prevent compromises and preserve breast aesthetics. Case report: A 14-year-old patient, seen at a tertiary hospital in São Luís, with complaints of pain and hardened tumor lesion in the left breast, diagnosed with osteochondroma. The treatment required the performance of a team composed of a thoracic surgeon and a mastologist to obtain results without functional and aesthetic compromise for the patient. The patient had as main complaint the limitation of movement, dyspnea and pain in the region of the lesion. She underwent a surgical procedure that consisted of an incision through the infra-mammary fold, detachment of the gland by the subfascial plane, opening of the pectoralis major muscle, approach of the rib and resection of the lesion without opening the pleura by the thoracic surgeon. The reconstruction of the breast defect was made with local flaps and closed by planes maintaining an adequate cosmetic and functional breast result. In clinical evaluation after the procedure, she had no complaints and no apparent lesions on CT scan. Malignancy of the disease is an important and feared complication, although tumors usually present with low grade, there are clinical signs of malignancy that should be monitored in these patients, such as the growth of exostosis after bone maturity, neuropraxia and symptoms associated with organ pressure close to injuries.

Introduction: Breast cancer has the highest incidence, prevalence, and mortality rate among malignant neoplasms in women worldwide (excluding non-melanoma skin cancer). Although there are well-defined treatments, they are still controversial during pregnancy: surgery seems safe and chemotherapy (CT) poses no harm to the fetus, especially if applied late in pregnancy. Hormone therapy (HT) and radiation therapy (RT) are prone to cause fetal damage. In patients diagnosed with pregnancy during treatment, there are no clear procedures about terminating the pregnancy or ceasing CT and RT. In these cases, it is necessary to monitor the patient and the fetus taking into account the woman’s will - especially if the tumor has estrogen and progesterone receptors, increasing the chance of relapsing or stop responding to CT. This study reports a case in which the hormones of pregnancy influenced a major recurrence of breast cancer, which diminished shortly after the birth. Case report: A 35-year-old woman, diagnosed with infiltrating ductal carcinoma in the left breast, underwent sectorectomy, axillary lymph nodes excision, and RT with an insufficient response. Subsequently, left tumor recurrence arose and mastectomy was performed. In the follow-up, she underwent CT and RT, with poor response. In the interim, it was discovered that the patient was pregnant, thus referred from oncology to gynecology for the interruption, since there was a considerable recurrence in the left breast plastron. Sixth -times pregnant, with five vaginal deliveries, the latest one six years before, all pregancies without complications. She was advised to terminate pregnancy but remained adamant in maintaining the pregnancy. She underwent an obstetric ultrasound showing a viable fetus of six weeks and six days of gestational age (GA). At 22 weeks of pregnancy, she was referred to the hospital by the oncologist for the interruption, as the plastron on the left breast was growing, with CT failure. The patient acknowledged that, with this GA, the fetus’s chance of survival was low. Yet, she opted for pregnancy continuation. Later she was sent by the prenatal care to the maternity hospital at 32 weeks of GA, aiming at delivery and a new CT protocol afterwards. She started corticosteroids for pulmonary development of the conceptus and endured cesarean delivery with bilateral adnexectomy. Female newborn, 1.830g, 8/9 APGAR score and 32 weeks and 5 days Capurro, transferred to the neonatal ICU (intensive care unit) due to prematurity. The patient was evaluated few months after delivery: great spontaneous resolution of the plastron in the left breast, with no effect of pregnancy hormones and responsive to CT. Follow-up in the oncology department.

Published: January 2022

Introduction: Phyllodes tumor of the breast (PT) is a rare neoplasm, characterized by stromal and epithelial elements, and accounts for approximately 1% of breast cancer in women. There are three subtypes, according to the World Health Organization, based on histological features: benign, borderline and malignant. Pathogenesis, prognostic and biologic characteristics are unknown, thus the difficulty in assessing the recurrence risk of the tumor. In general, the treatment approach is breast conserving surgery, with a margin >1 mm, in order to prevent recurrence. There is currently a great concern with the increase of breast cancer cases in young women, which represents a significant burden in developing countries such as Brazil. The mean age of presentation of malignant PT is 40 years old, and there are rare cases reported in very young adults, 18 and 23 years old. There is one case series in the literature of benign PT in 14 to 16 years old adolescents. However, we did not find any report of malignant PT in this age group. Given the rarity of the case and the current importance of breast cancer in young women, we report a rare case of malignant PT in a patient with only 14 years of age. Case report: A 14-year-old female came to a visit due to an abnormal growth of the breast over the last nine months. She had no other complaints or comorbidities. In her family history, she has one aunt that had breast cancer. On physical examination, the patient presented gigantomastia and stretch marks stretch with a reddish appearance. It was identified a nodule of 5.0 cm located in the upper inner quadrant of the right breast, and the axillary region showed no abnormalities. On the ultrasound, the nodule measured 5.7 cm. The patient underwent a segmentary resection of the lesion. The anatomopathological study revealed a malignant PT with a low differentiation grade, measuring 7.0 cm in its largest dimension and free margins, however exiguous. Immunohistochemistry of the lesion revealed the expression of Ki-67, p-63 protein, cytokeratin-14, Bcl-2 and vimentin. On the magnetic resonance imaging, only surgical alterations were observed with no macroscopic residual tumor and the armpit was negative. In order to extend the surgical margins, a second approach was performed, associated with a reduction mammoplasty. The anatomopathological study then showed no residual neoplasm and free margins. The patient had good postoperative recovery and was satisfied with the esthetic results. After consultation with the oncologist, no adjuvant treatment was indicated.

Published: January 2022

Introduction: Lymphangioma or cystic hygroma is a rare and benign lesion usually found in children or newborns, hardly described after two years of age. It is characterized by congenital obstruction of the lymphatic vessels, which causes dilation and accumulation of lymph inside it. In adults, it can be secondary to trauma and can occur in the neck, head and, more rarely, in the breast and armpit3 . In this study we present an atypical case of recurrent axillary lymphangioma in an elderly patient. Case report: Female patient, 71 years old, with no history of neoplasms, was referred to the breast surgery center in December 2019 due to bulging in the right axillary region over the past three months, with progressive increase in size. She was submitted to a puncture with complete emptying of the lesion, however, she developed a recurrence of the condition. On initial physical examination, she had bulging in the right axillary region, painless on palpation, softened, measuring about 10.0 cm. Investigation continued with mammography and ultrasound, which did not show any breast changes, but showed a cystic lesion in the right axillary extension of 9.0 cm. The patient returned in March 2020 with recurrence of the condition after another relief puncture, presenting a lesion of about 18 cm, in the same topography and with the same aspect of the previous lesion on physical examination. Initially, it was opted for resection of axillary cyst, however, due to the COVID-19 pandemic, the patient’s age and probable benign etiology of the lesion, clinical control was chosen. In August 2020, she presented worsening of the axillary bulging condition, with a lesion measuring about 20.0 cm. We proceeded with the definitive surgical approach with the excision of an axillary cyst with resection of a skin spindle in August 2020. The procedure occurred without complications. The final anatomopathological result showed in cytology the presence of proteinaceous material and mature lymphocytes, corroborating the definitive diagnosis of lymphangioma. During the postoperative period, the patient presented recurrence of the axillary bulging condition, with the need for relief drainage, due to local discomfort. We opted for a new surgical approach to drainage. During the operation, it was possible to observe remnants of the lymphangioma capsule completely adhered to the pectoralis major muscle. We proceeded with vacuum drain and excision of samples from the lesion attached to the muscle was continued. The findings confirmed the diagnosis of lymphangioma. The patient recovered well, with a drain removed on the 10th post operation day. In view of the current situation of the COVID-19 pandemic, it was decided to maintain the clinical follow-up of the patient and she has not had recurrence of the condition so far (five months of follow-up).

Introduction: Assessing limb functionality is difficult in the mastologsit’s office. The growing incidence of breast cancer and consequently of cancer treatment and patient survival justifies the search for reliable quantitative evaluation methods to diagnose and correlate treatment-related chronic functional sequelae. In addition, many clinical limitations are not associated with the absolute values of strength and mobility of the upper limb. Objectives: To verify if the EORTC-BR23, SPADI and BCTOS questionnaires are able to differentiate known groups in relation to functionality. Methods: Study approved by the Ethics Committee under number 782/2014. Observational cross-sectional, non-randomized study. 48 patients treated with conservative surgery associated with radiotherapy were selected through a non-probabilistic sample for convenience and divided into two groups: G1 composed of 24 women with a minimum of two functional deficits diagnosed by goniometry and dynamometry; and G2 - women without deficits and functional complaints. Sequelae were considered a 10-degree reduction in abduction or flexion, or a 12% difference in loss of strength in the limb homolateral to breast cancer. All patients answered the SPADI, BCTOS and EORTC-BR 23 questionnaires. They sought to assess the domains of the questionnaires that would be able to separate the groups. The Man-Whitney test was used to compare the groups. If the questionnaires were able to distinguish the groups, a potential cut-off point was identified by the ROC curve. Grant by FAPESP project n. 2014 08197-0. Results: Regarding groups G1 and G2, a difference was observed in all domains of the SPADI questionnaires [pain (p <0.001) and disability (p <0.001)] and BCTOS [(functional (p=-0.04), cosmesis (p=0.025), breast pain (p=0.053) and edema (p=0.007)], and in EORTC-BR 23 only in the “Symptoms of the Arm” domain (p=0.01). SPADI pain (area = 0.808, p <0.001) and disability (area = 0.885, p<0.001) were the questionnaires that better separated the groups, with cutoff points for SPADI pain ≤38 (sensitivity 66.7%, specificity 79.17%) and SPADI disability ≤41.25 (sensitivity 88.3%, specificity 91.7%). Conclusions: In patients undergoing conservative treatment and radiotherapy, it was possible to use SPADI and BCTOS to diagnose functional sequelae, since they were able to differentiate the previously known groups in all assessment domains, and SPADI was able to better identify the groups. This fact facilitates the use of these questionnaires in clinical practice, aiming at assessing the sequelae associated with treatment.
Improving Graduate Futures and Employability Through Embedded Industrial Experience

The financial cost to individuals of higher education is now regularly exceeding £50k before maintenance in the UK; consequently, students are more concerned than ever that their degree should offer value for money when they enter the jobs marketplace. Overshadowed by long-term debt, lack of career options and job offerings with low salary, student numbers in the arts, languages, humanities and philosophy areas have suffered compared to most STEM disciplines (Universities UK, 2018). Computer science, I.T. and computing tend to buck this trend (HESA, 2020), and, with a drive toward reskilling the workforce for a more technology-focussed future, this suits Government strategy. However, graduate employers want to hire individuals who are well rounded and have experience; businesses identify that more general workplace experience is key. The subsequent sections describe a level 7 (Master’s) capstone project module, Commercial Development Practice, dedicated to fulfilling these employer requirements by focussing on project processes rather than project products. The practicalities of running this module and considerations that have been key for the successful application of this technique over the 14 years the module has been running are discussed. The curriculum, pedagogic approaches and assessment methods are presented. The evaluation of this approach, which analyses the impact and student experience and perception of the module using data gathered since 2015, has found that participants gain valuable skills, experience and confidence which leads to more employable graduates.

This article outlines an exploratory study that investigated students’ perceptions of the benefits and disadvantages of lecture recordings delivered as part of an introductory chemistry program in the UK during the COVID-19 lockdown in Spring 2020. Three features of these lecture recordings are considered: 1) the production of a series of mini-lectures rather than 50 minute recordings; 2) the inclusion of quiz questions in the video timeline; and 3) the inclusion of a picture-in-picture talking head showing the instructor alongside a captured screen. Analysis of survey data indicates that a majority of students felt that each of these features had a positive impact on their learning and/or experience, with a significant number expressing a preference for the retention of online lectures after the resumption of on-campus teaching. Qualitative data provides valuable insight regarding the specific aspects of the recorded lectures that were perceived to enhance the student experience, supporting the design of future provision both during and beyond the COVID-19 pandemic. The generalizability of the recommendations is also discussed, along with the limitations of the study.

In its development, the study of sports achievement is always closely related to the physical readiness of athletes. In addition to other supporting factors, such as nutritional status or mental competition as well as good technical mastery, the physical condition factor is still considered to have a major impact on athlete achievement. relation to the determination of the exercise program is still not optimal. For this reason, in this study, the main objective was to find out about the physical condition of the taolu athletes before participating in the national championship which would later be used as the basis for determining the training program. In this research, the researcher used a quantitative descriptive method using surveys as well as tests and measurements. The instrument used in taking the data is a test instrument that has been arranged in a test and measurement guide book and is in accordance with the needs of the physical conditions used in the Wushu Taolu sport. The results showed that athletes with very good condition were 17.32%, in the good category as much as 34.70%, in the sufficient category as much as 23.46%, in the less category as much as 13.29%, and in the poor category as much as 11.23%. . From the results of the tests carried out, the physical condition of the Wushu Taolu athletes in Kediri City was in the good category. Furthermore, researchers who will develop this research can cover a wider area, because this research is only limited to wushu taolu athletes in the city of Kediri.

This note presents the characterization of the families of star, helm, flower and complete graphs by total vertex stress. The note does not present results for many families of graphs but, it highlights important philosophical (math. phil.) aspects for further research. In particular the novelty concepts of forgiven contradictions denoted by, iff\(_f\) as well as iffness and \(f\)-statements are introduced. The author suggests that the characterization of other families of graphs by total vertex stress is possible.

During drilling and logging, depth alignment of well logs acquired in the same borehole section at different times is a vital preprocessing step before any petrophysical analysis. Depth alignment requires high precision as depth misalignment between different log curve measurements can substantially suppress possible correlations between formation properties, leading to imprecise interpretation or even misinterpretation. Standard depth alignment involves cross correlation, which typically requires user intervention for reliability. To improve the depth alignment process, we apply deep-learning techniques and propose a simple and practical implementation of a one-dimensional (1D) supervised convolutional neural network (1D CNN). We train seven CNN models using different log measurements, such as gamma ray, resistivity, P- and S-wave sonic, density, neutron, and photoelectric factor (PEF), to estimate depth mismatches between the corresponding raw logging-while-drilling (LWD) and electrical-wireline-logging (EWL) logs of each measurement type. Our deep-learning approach avoids manual feature extraction; hence, no high-level petrophysical knowledge is needed by our algorithms. We use log data from six wells from the Ivar Aasen Field in the Norwegian North Sea. Four of the six wells constitute the entire data set for training and model selection, in which we compare three search algorithms during the hyperparameter tuning. Only two wells have both LWD and EWL log suites. These wells are used for depth-shift inference. We focus on estimating bulk shifts, and we assume the existence of small pattern differences. We assess our results by visual inspection and quantitative metrics such as the Pearson correlation and Euclidean distance. We also compare the CNN depth shifts with depth shifts obtained using the classical cross-correlation method. The CNN performs well and is competitive with cross correlation. CNN performs better for some log types—resistivity, for instance—than others. Several factors influence our results, including the quality of the input data, borehole conditions, pattern differences between LWD and EWL, and significant stretch/squeeze effects. Differences between the mean Pearson correlation computed after CNN and the cross-correlation depth-matching process are of the order of 10–1 and 10–2. Our CNN approach is, therefore, a potential alternative to current depth-matching methods, which may reduce the amount of user intervention required from the petrophysicist.

With the end of oil production, the need for safe and economically efficient plug and abandonment (P&A) operations increases. Due to the high costs related to traditional P&A processes, the possibility of shale bonding to the well casing, forming a natural barrier, is explored. Here, we present a unique laboratory experiment of creeping shale in a pressure cell, which is monitored during the creep and bonding processes using the ultrasound pulse-echo (PE) and pitch-catch (PC) measurement techniques. The combination of continuous PE and PC measurements in one direction, with discrete measurements in 5° intervals, and the logging of confining pressure, temperature, and permeability allows an improved understanding of the bonding processes and the interpretation of parameters derived from PE and PC measurements. We find that the initial creep of the shale occurs when the confining pressure is increased from 5 to 9 MPa, resulting in significant changes observed in the acoustic impedances derived from PE and PC measurements. However, as permeability is still high, we assume that channels are still open. With the increase in confining pressure to 13 and 14 MPa, respectively, we observe a decrease in permeability corresponding to an overall decrease in signal strength for the PC data of up to 25 dB and a decrease in the PE group delay parameter of up to 0.6 μs corresponding to a change in acoustic impedance from about 1 MRayl to about 3 to 3.5 MRayl. Large variations with direction can be observed. Combining the information of PE and PC gives a good impression of the bonding processes.

Problem-solving is one of the skills that is crucial to equip students to face a variety of challenges in the future as well as related to the development of their lifelong literacy skills. One of the potential solutions for promoting students’ problem-solving skills is introducing Computational Thinking. However, in the context of schools in East Kalimantan, both teachers and students have not been familiar with Computational Thinking. Therefore, this current pilot study aimed at introducing Computational Thinking to teachers, especially primary school teachers, by developing a workshop and a module suitable to the local contexts and needs. This study involved 22 primary school teachers from Kutai Kartanegara Regency who had no prior knowledge and experience concerning Computational Thinking. The teachers were trained the basic concepts of CT and how to implement CT in the class especially in relation to literacy aspects. Afterwards, the teachers were assigned to develop a CT-infused lesson and did a self-reflection on the process. The findings from the post-workshop questionnaires indicated that most teachers showed positive attitudes towards CT and implementing CT in their lessons. Furthermore, they also voiced out that they would like to learn further about CT, particularly related to Literacy and the Minimum Competency Assessment (AKM).
