Recurrent genetic variants and prioritization of variants of uncertain clinical significance associated with hereditary breast and ovarian cancer in families from the Region of Murcia.

Objectives: Hereditary breast and ovarian cancer (HBOC) follows an autosomal dominant inheritance pattern of cancer susceptibility genes. The risk of developing this disease is primarily associated with germline mutations in the BRCA1 and BRCA2 genes. The advent of massive genetic sequencing technologies has expanded the mutational spectrum of this hereditary syndrome, thereby increasing the number of variants of uncertain clinical significance (VUS) detected by genetic testing. Methods: A prevalence study of HBOC was performed within 2,928 families from the Region of Murcia, in southeastern Spain. Genetic testing enabled the identification of recurrent pathogenic variants and founder mutations, which were mainly related to the BRCA1 and BRCA2 genes. VUS testing was performed using a prioritization algorithm designed by our working group. Results: Variants c.68_69del, c.212+1G>A, and c.5123C>A were detected in 30 % of BRCA1 carriers, whereas exon 2 deletion concurrent with c.3264dupT, c.3455T>G and c.9117G>A variants were found in 30 % of BRCA2 carriers. A total of 16 VUS (15 %) were prioritized. Conclusions: The genotype-phenotype correlation observed in our study is consistent with the scientific literature. Furthermore, the founder effect of c.1918C>T (BRCA1) and c.8251_8254del (ATM) was verified in the Murcian population, whereas exon 2 deletion (BRCA2) was proven to be a Spanish founder mutation. Our algorithm enabled us to prioritize potentially pathogenic VUS that required further testing to determine their clinical significance and potential role in HBOC.

A comparison of pharmacokinetics software for therapeutic drug monitoring of piperacillin in patients with severe infections.

OBJECTIVE: To evaluate the predictive performance of population pharmacokinetic models for piperacillin (PIP) available in the software MwPharm, TDMx and ID-ODs for initial dosing selection and therapeutic drug monitoring (TDM) purposes. METHODS: This is a prospective observational study in adult patients with severe infections receiving PIP treatment. Plasma concentrations were quantified by ultra-high performance liquid chromatography coupled to tandem mass spectrometry. The differences between predicted and observed PIP concentrations were evaluated with Bland-Altman plots; additionally, the relative and absolute bias and precision of the models were determined. RESULTS: A total of 145 PIP plasma concentrations from 42 patients were analysed. For population prediction, MwPharm showed the best predictive performance with a mean relative difference of 34.68% (95% CI -197% to 266%) and a root mean square error (RMSE) of 60.42 µg/mL; meanwhile TDMx and ID-ODs under-predicted PIP concentrations. For individual prediction, the TDMx model was found to be the most precise with a mean relative difference of 7.61% (95% CI -57.63 to 72.86%), and RMSE of 17.86 µg/mL. CONCLUSION: Current software for TDM is a valuable tool, but it may also include different population pharmacokinetic models in patients with severe infections, and should be evaluated before performing a model-based TDM in clinical practice. Considering the heterogeneous characteristics of patients with severe infections, this study demonstrates the need for therapy personalisation for PIP to improve pharmacokinetic/pharmacodynamic target attainment.

Influence of Thermal Annealing Temperatures on Powder Mould Effectiveness to Avoid Deformations in ABS and PLA 3D-Printed Parts.

Fused deposition modelling (FDM)-printed parts can be treated with various post-processes to improve their mechanical properties, dimensional accuracy and surface finish. Samples of polylactic acid (PLA) and acrylonitrile butadiene styrene (ABS) parts are treated with annealing to study a ceramic powder mould's effectiveness in order to avoid dimensional part deformation. The variables chosen are annealing temperatures and the usage of a ceramic powder mould to avoid part deformations. A flexural strength test was carried out to evaluate the mould's influence on the mechanical properties of the part. The effectiveness of the mould has been evaluated mainly attending to the length of the part, because this is the dimension most affected by deformation. A polynomial approximation to a deformation's length and the effectiveness of the mould allows for their prediction. Results obtained show that effectiveness increases with the annealing temperature. Nevertheless, mould effectiveness decreases when parts are fabricated with PLA, because it is a semi-crystalline thermoplastic, and it suffers a lower shrinkage during thermal post-process than amorphous polymers such as ABS. Attending to the flexural strength test, mould has no significant influence on the mechanical properties of the treated parts in both materials studied.

Next step in molecular genetics of hereditary breast/ovarian cancer: Multigene panel testing in clinical actionably genes and prioritization algorithms in the study of variants of uncertain significance.

INTRODUCTION: BRCA1 and BRCA2 are the two main genes causing hereditary breast and ovarian cancer (HBOC). However, thanks to the development of Next Generation Sequencing (NGS), other genes linked to this syndrome (CHEK2, BRIP1, ATM and PALB2 among others) can be analysed. MATERIAL AND METHODS: an analysis by multigene panel testing was performed in 138 index cases (ICs) from HBOC Spanish families with a previous non-informative result for BRCA1/2. The BRCA Hereditary Cancer Master™ Plus kit, including 26 actionable and candidate genes related to HBOC was employed. Once classified, an algorithm was employed to prioritized those variants of unknown significance with a higher risk of having a deleterious effect. Moreover, a mRNA splicing assay was performed for the prioritized VUS c.3402+3A > C in ATM, located at intron 23. RESULTS: A total of 82 variants were found: 70 VUS and 12 pathogenic or probably pathogenic variants. The diagnostic yield in actionable genes non-BRCA was 7.97% of the total tested ICs. Overall, 19 VUS were prioritized, which meant 27% of the 70 total VUS. RNA analysis of the variant 3402+3A > C confirmed a deleterious impact on splicing. DISCUSSION: The implementation of a multigene panel in HBOC studied families improved the diagnostic yield, concordant with results obtained in previous publications. Due to the important number of VUS obtained in NGS, the application of a prioritization algorithm is needed in order to select those variants in which it is necessary to conduct further studies.

La aplicación del estudio ACOSOG (American College of Surgeons Oncology Group) a 18 pacientes con ganglio centinela positivo evitó la linfadenectomía axilar y redujo el coste en 37.530 €. La RMN preoperatoria en cáncer de mama aportó un beneficio en el tratamiento de 31 pacientes; una selección de pacientes más precisa habría supuesto un ahorro de 37.179 €. Las ampliaciones de márgenes quirúrgicos sin hallazgo de tumor residual determinaron un gasto de 11.592 €.Conclusiones-La cirugía conservadora de mama con biopsia selectiva de ganglio centinela en régimen de cirugía mayor ambulatoria supuso un ahorro importante de recursos sin comprometer el bienestar y pronóstico de las pacientes.-Los costes asociados a la realización de una RMN preoperatoria sin selección previa de pacientes y las reintervenciones de ampliación de márgenes determinaron un gasto evitable en buena parte de las pacientes.(AU)

ObjectiveThe aim of our study was to identify the costs associated with the diagnosis and surgical procedure in a cohort of patients with early breast cancer.MethodWe performed a costs study, referred to the preoperatory radiological-histological study, surgical procedure and inpatient/outpatient health service in a cohort of 224 patients diagnosed and operated on early-stage breast from June 2012 to December 2016.ResultsBreast conserving surgery in outpatient health service applied to lumpectomy with sentinel lymph node biopsy compared to carrying it out in the inpatient setting, contributed to a saving of 2085€ per patient, and total of 289,815€. Following the ACOSOG (American College of Surgeons Oncology Group) trial in 18 patients with tumor-involved sentinel node, no further axillary specific treatment (completion of lymphadenectomy) was made, allowing a saving of 37,530€. In most patients our study have not showed benefit from diagnostic/preoperative breast MRI, leading to an over cost of 37,179€. The surgical rescission without showing the presence of residual tumor burden, led to an additional cost of 11,592€.Conclusions-Breast conserving surgery with sentinel lymph node biopsy in outpatient health service supposed an important economical saving of resources, without compromising the well-being and prognosis of our patients.-The diagnostic/preoperative MRI in all the patients and the surgical rescissions led to an over cost that could be avoided in most of the cases.(AU)

Frailty Assessment in a Stable COPD Cohort: Is There a COPD-Frail Phenotype?

The frailty syndrome increases the morbidity/mortality in older adults, and several studies have shown a higher prevalence of this syndrome in patients with Chronic Obstructive Pulmonary Disease (COPD). The aim of this study was to identify the characteristics of frail patients with COPD to define a new phenotype called "COPD-frail." We conducted a cross-sectional study in a cohort of patients with stable COPD, classified as either frail, pre-frail, or non-frail. Sociodemographic, clinical, and biochemical variables were compared between the three groups of patients. The study included 127 patients, of which 31 were frail, 64 were pre-frail, and 32 non-frail. All subjects had FEV1/FVC below the lower limit of normal (range Z-score: -1.66 and -5.32). Patients in the frail group showed significantly higher scores in the mMRC (modified Medical Research Council) scale, the CAT (COPD Assessment Test), and the BODE (Body mass index, airflow Obstruction, Dyspnea, and Exercise capacity) index. They also showed differences in symptoms according to GOLD (Global Initiative for Chronic Obstructive Lung Disease), as well as more COPD exacerbations, less physical activity, more anxiety and depression symptoms based on HADS (Hospital Anxiety and Depression Scale), and lower hemoglobin, hematocrit, and 25-hydroxycholecalciferol levels. Variables with independent association with frailty included the mMRC score, the HAD index for depression and age. In summary, differential characteristics of frail patients with COPD encourage the definition of a "COPD-frail" phenotype that-if identified early-would allow performing interventions to prevent a negative impact on the morbidity/mortality of these patients.

Effect of a Powder Mould in the Post-Process Thermal Treatment of ABS Parts Manufactured with FDM Technology.

The post-process thermal treatment of thermoplastics improves their mechanical properties, but causes deformations in parts, making them unusable. This work proposes a powder mould to prevent dimensional part deformation and studies the influence of line building direction in part deformations in a post-process thermal treatment of 3D printed polymers. Two sets of ABS (acrylonitrile butadiene styrene) test samples manufactured by fused deposition modelling (FDM) in six different raster directions have been treated and evaluated. One set has been packed with a ceramic powder mould during thermal treatment to evaluate deformations and mould effectiveness. Thermogravimetric tests have been carried out on ABS samples, concluding that the thermal treatment of the samples does not cause degradations in the polymeric material. An analysis of variance (ANOVA) was performed to study internal building geometry and mould influence on part deformation after the thermal treatment. It can be concluded that powder mould considerably reduces dimensional deformations during the thermal treatment process, with length being the most affected dimension for deformation. Attending to the length, mould effectiveness is greater than 80% in comparison to non-usage of moulding, reaching 90% when the building lines are in the same direction as the main part.

Patrones de desayuno en estudiantes universitarios de España, Túnez y Estados Unidos. Factores antropométricos, sociodemográficos y de estilo de vida / Breakfast patterns in university students of Spain, Tunisia, and The United States of America. Anthropometric, sociodemographic and lifestyle factors

La mayoría de los estudios apoyan la tesis de que el desayuno es la comida más importante del día. Un desayuno adecuado contribuye a lograr un patrón dietético global saludable y a mejorar la calidad de la dieta. El objetivo de este estudio fue determinar los principales patrones de desayuno en tres poblaciones universitarias de España, Túnez y Estados Unidos, analizar sus semejanzas y diferencias y estudiar la influencia de factores antropométricos, sociodemográficos y de estilo de vida en la adherencia a cada patrón. Se realizó un estudio transversal con datos de 730 estudiantes matriculados en las Universidades de Castilla-La Mancha, Cartago e Internacional de Florida en 2013. El consumo de alimentos se obtuvo mediante dos recordatorios de 24 horas, no consecutivos, uno de ellos en fin de semana. Los patrones se identificaron mediante análisis factorial exploratorio. La adherencia de los estudiantes a cada patrón se evaluó usando las puntuaciones factoriales. Se obtuvieron cuatro patrones para cada país. El principal patrón de los universitarios españoles incluyó pan, tomate, sal y aceite de oliva (varianza explicada: 20,85%); el principal de los tunecinos contenía pan, mermelada, nata y mantequilla (varianza explicada: 12,73%) y el principal de los americanos incluyó huevos, leche entera y azúcares (varianza explicada: 10,77%). Género, peso, IMC o comer fuera de casa fueron factores que influyeron en la adherencia a diferentes patrones. El estudio mostró la coexistencia de patrones tradicionales con otros occidentalizados y modelos transicionales intermedios. No se determinó un patrón generalizable asociado a mejores resultados del IMC(AU)

Most studies support the conclusion that breakfast is the most important meal of the day. An adequate breakfast contributes to achieving a healthy global dietary pattern and improving quality of diet. The objective of this study was to determine the main breakfast patterns of three university populations from Spain, Tunisia, and The United States of America, analyze their similarities and differences, and study the impact of anthropometric, sociodemographic and lifestyle factors on the adherence to each pattern. A cross-sectional study was developed with data from 730 students enrolled at the University of Castilla-La Mancha, University of Carthage, and Florida International University, during 2013. Food consumption data were obtained by means of two non-consecutive 24-hour recalls including one weekend day. Exploratory factor analysis was conducted to identify breakfast patterns. Factor scores were used to assess students' adherence to each pattern. Four breakfast patterns were obtained for each country. The main pattern of the Spanish students included bread, tomato, salt, and olive oil (explained variance: 20.85%); the main model of the Tunisians included bread, jam, cream and butter (explained variance: 12.73%); and the first pattern of the Americans was characterized by eggs, whole milk and sugars (explained variance: 10.77%). Gender, weight, BMI or eating out of home were factors that influenced the adherence to different patterns. Breakfast patterns obtained in this work showed the coexistence of traditional models with westernized and transitional ones. It was not determined a generalizable pattern associated with better BMI results(AU)

Food consumption in Tunisian university students and its association with sociodemographic characteristics and lifestyle behaviours.

OBJECTIVE: This study aimed to characterise food consumption among students at the University of Carthage (Tunisia), assessing quality of diet and main dietary patterns, and their association with potential conditioning factors. DESIGN: Cross-sectional study. Participants self-reported food consumption in two 24-h recalls and information about sociodemographic, anthropometric and lifestyle characteristics such as BMI, birthplace, physical activity, eating places or kitchen appliances. Mediterranean Diet Score (MDS) and the Nutrient Rich Foods (NRF) index (NRF9.3) were used to assess diet quality. Exploratory factor analysis was conducted to identify eating patterns. Linear regression models were used to test the association of dietary patterns with the diet quality markers. SETTING: Students at the University of Carthage, Tunisia. PARTICIPANTS: 132 students. RESULTS: Almost 96 % of participants need shifts towards healthier food. Four main food patterns were identified 'Traditional food', 'Transitional food', 'European breakfast' and 'Western food'. 'Traditional food' was the first dietary model, positively associated with MDS and NRF9.3. Women showed higher adherence to 'European breakfast' and higher quality of diet by NRF9.3. Students eating out of home showed higher adherence to 'Western food', those who never kept a regular schedule of meals consumed lower amount of vegetables and tubers, and sedentary or low active students had a higher intake of ready-to-eat products. CONCLUSIONS: Diet quality of the participating Tunisian students is inadequate, but traditional Mediterranean diet remains the main pattern in spite of the advanced transitional nutrition. Some lifestyle risk behaviours affecting quality of diet were identified in this work, which supports the youth's particular vulnerability.

Comparison of Different Parameters to Evaluate Delamination in Edge Trimming of Basalt Fiber Reinforced Plastics (BFRP).

Delamination is one of the main problems that occur when machining fiber-reinforced composite materials. In this work, Types I and II of delamination are studied separately in edge trimming of basalt fiber reinforced plastic (BFRP). For this purpose, one-dimensional and area delamination parameters are defined. One-dimensional parameters (Wa and Wb) allow to know average fibers length while the analysis of area delamination parameters (Sd) allow to evaluate delamination density. To study delamination, different tests are carried out modifying cutting parameters (cutting speed, feed per tooth and depth of cut) and material characteristics (fiber volume fraction and fiber orientation). Laminates with a lower fiber volume fraction do not present delamination. Attending to one-dimensional parameters it can be concluded that Type II delamination is more important than Type I and that a high depth of cut generates higher values of delamination parameters. An analysis of variance (ANOVA) is performed to study area parameters. Although delamination has a random nature, for each depth of cut, more influence variables in area delamination are firstly, feed per tooth and secondly, cutting speed.

Precisión de la resonancia magnética, ecografía y mamografía en la medida del tamaño tumoral y su correlación con el tamaño histopatológico en el cáncer de mama primario / Accuracy of tumor size measurements performed by magnetic resonance, ultrasound and mammography, and their correlation with pathological size in primary breast cáncer

Introducción: El objetivo de este estudio fue evaluar qué prueba de imagen de las empleadas para medir el tamaño del cáncer de mama primario preoperatorio (mamografía, ecografía o resonancia magnética [RM]) se correlacionó mejor con el tamaño del tumor en la pieza quirúrgica postoperatoria. Métodos: Análisis retrospectivo de mujeres con diagnóstico de cáncer de mama y con indicación de tratamiento quirúrgico primario operadas desde enero del 2014 hasta diciembre del 2016. Se recogieron variables sociodemográficas, vinculadas a técnicas de imagen e histológicas. Los resultados se presentaron según edad, tamaño tumoral y tipo histológico. Resultados: Se estudió a 224 mujeres. Al comparar el tamaño mamográfico y de la RM con el histológico final no se encontraron diferencias significativas, tanto de forma global como teniendo en cuenta el grupo histológico o la edad, sin embargo, ambas infraestimaron significativamente los tumores grandes y sobrestimaron significativamente los pequeños. La ecografía infraestimó significativamente el tamaño del tumor, especialmente en tumores grandes, pacientes mayores y en los grupos de carcinoma ductal infiltrante (CDI) y CDI con carcinoma ductal in situ asociado (CDI + CDIS). La RM se correlacionó mejor con el tamaño tumoral histológico aunque sin diferencias estadísticamente significativas. Conclusiones: La RM parece ser el mejor predictor del tamaño del tumor en el cáncer de mama. El grupo histológico y el tamaño del tumor fueron claves en la estimación de la medida del tumor, por lo que se deben tener en cuenta en la planificación de la cirugía. La variable edad no interfirió en la interpretación de las imágenes

Introduction: The objective of this study was to determine which image test used to measure the size of pre-operative primary breast cancer (mammography, ultrasound or magnetic resonance imaging [MRI]) correlated best with the size of the tumor in the postoperative surgical specimen. Methods: A retrospective analysis was conducted of women diagnosed with breast cancer for which primary surgical treatment was indicated and who underwent surgical intervention between January 2014 and December 2016. Sociodemographic, imaging and histological variables were collected. The results are presented by age group, tumor size and histological type. Results: In the 224 women studied, mammography and MRI tumor sizes were compared with pathology study tumor measurements, revealing no significant differences, both overall and based on histologic type or age. However, both significantly underestimated large tumors and significantly overestimated small tumors. Ultrasound significantly underestimated tumor size, especially in large tumors, older patients and in infiltrating ductal carcinoma (IDC) and infiltrating ductal carcinoma with associated ductal carcinoma in situ (IDC + DCIS). MRI correlated best with histological tumor size, although with no statistically significant differences. Conclusions: MRI is the best predictor of tumor size in breast cancer. Histologic type and tumor size are key parameters when estimating tumor size and should be taken into account when planning surgery. Patient age does not interfere with the interpretation of imaging tests

Papel de las colecciones de piezas anatómicas en la enseñanza de la anatomía patológica / The relevance of anatomical specimens in the teaching of Pathology

La trascendencia de la museología relacionada con la anatomía y la anatomía patológica radica tanto en la conservación de piezas anatómicas naturales o de sus reproducciones, como en la posibilidad de ofrecer un valioso material para fines didácticos e investigadores. Los primeros fundamentos para la enseñanza anatómica fueron los theatrum anatomicum y los «gabinetes anatómicos» de las cátedras de anatomía de la facultades de medicina europeas, a los que sucedieron en siglos posteriores los museos anatómicos y anatomopatológicos. Tras una época de auge durante el siglo xviii, la mayor parte de ellos sufrieron un proceso de decadencia progresiva que llevó a la pérdida de muchos de ellos. En la actualidad se observa un interés creciente en la recuperación y puesta en valor de estas colecciones. Este trabajo muestra una aproximación histórica de su desarrollo y una revisión de la situación actual de los principales museos de España y de Europa

The relevance of museums of anatomy and pathology lies both in the conservation of anatomical specimens and their excellent reproductions and their use in education and research. The teaching of anatomy dates from ancient times, originating in the Theatrum Anatomicum and anatomical cabinets, located in the anatomy lecture rooms of European medical schools. These were followed by museums of anatomy and pathology in successive centuries. However, after a golden period in the XVIII century, there was a progressive decline which eventually led to a dramatic loss of many museums. Currently, there is a growing interest in the recovery and importance of these collections. We present an historical approach to their development and a review of the current situation in the principal anatomical museums of anatomy in Spain and the rest of Europe

Delamination Study in Edge Trimming of Basalt Fiber Reinforced Plastics (BFRP).

Although there are many machining studies of carbon and glass fiber reinforced plastics, delamination and tool wear of basalt fiber reinforced plastics (BFRP) in edge trimming has not yet studied. This paper presents an end milling study of BFRP fabricated by resin transfer molding (RTM), to evaluate delamination types at the top layer of the machined edge with different cutting conditions (cutting speed, feed rate and depth of cut) and fiber volume fraction (40% and 60%). This work quantifies delamination types, using a parameter Sd/L, that evaluates the delamination area (Sd) and the length (L), taking into account tool position in the yarn and movement of yarns during RTM process, which show the random nature of delamination. Delamination was present in all materials with 60% of fiber volume. High values of tool wear did not permit to machine the material due to an excessive delamination. Type II delamination was the most usual delamination type and depth of cut has influence on this type of delamination.
