Purpose: To evaluate MRI and histological concordance in prostate cancer (PCa) identification via mapped transperineal biopsies., Methodology: Retrospective per-lesion analysis of patients undergoing MRI and transperineal biopsy at the Valencian Institute of Oncology (2016-2024) using CAPROSIVO PCa data. Patients underwent MRI, with or without regions of interest (ROI), followed by transperineal biopsies (3-5 cores/ROI, 20-30 systematic). Sensitivity (Se), specificity (Sp), negative predictive value (NPV), positive predictive value (PPV), and area under the curve (AUC) were calculated, considering PI-RADS 3 lesions as positive or negative. Gleason Grade Group (GG) > 1 defined clinically significant PCa (csPCa)., Results: 1817 lesions were analyzed from 1325 patients (median age 67, median PSA 6.3 ng/ml). 53% MRI were negative, GG > 1 prevalence was 38.4%. MRI-negative cases showed varying PCa rates: 57.4% negative, 30.2% GG 1, and 12.4% GG > 1. PI-RADS 3 lesions had mixed outcomes: 45.6% benign, 13.1% GG 1, and 41.3% GG > 1. 9.2% PI-RADS 4-5 lesions were negative, 9% GG 1, and 81.7% GG > 1. For PI-RADS 3 lesions considered positive, Se, Sp, NPV, PPV, and AUC were 82.9%, 75%, 87.6%, 67.4%, and 0.79 respectively. Considering PI-RADS 3 as negative yielded 64.8% Se, 91% Sp, 80.6% NPV, 81.7% PPV, and 0.78 AUC., Conclusion: MRI and mapped prostate biopsies exhibited moderate concordance. MRI could miss up to one in five csPCa foci and misinterpret one in three ROIs. Careful MRI interpretation is crucial for optimizing patient care., (© 2024.

FMD remains endemic in many Asian and African countries where multiple variants of serotypes O and A, among others, currently circulate. Due to lack of cross-protection between serotypes and incomplete protection between some strains even within a serotype, an important challenge for the application of effective vaccination programs is to select highly immunogenic and widely cross-reactive vaccine strains. Adaptation of a candidate field virus for use as a vaccine can be quite complex, so that whenever possible, the use of well-established vaccine viruses could have enormous advantages. FMD vaccine strains harmonized for use in South America have shown excellent results in FMD control, not only in the region, where it is still used systematically as a preventive measure, but also more recently in some Asian countries. To gain further insight into the immunogenic spectrum of these strains, VN tests (VNT) were performed with sera from cattle and/or pigs vaccinated with monovalent (type O) or trivalent (types O and A) formulations against 122 type O and 32 type A field viruses isolated from 35 countries in Asia and Africa, belonging to different lineages. Almost all VNT titers obtained were within the expected protective level, indicating the wide immunogenic spectrum of high potency FMD vaccines formulated with O 1 Campos, A24 Cruzeiro and A Argentina 2001 South American vaccine strains belonging to EURO-SA topotypes against currently active viruses from other topotypes. These in vitro results are in line with previously reported in vivo challenge tests in pigs against three A/ASIA/Sea-97 isolates and two isolates belonging to type O lineages O/SEA/Mya-98 and O/ME-SA/Ind-2001e., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Sternal morphological variations differ among populations and are influenced by the interaction between inheritance, development, and environment. There are currently no studies that include all variability from a morphogenesis approach following a homogeneous definition. The aims of this study were (a) to develop a standardized method for the anatomical study of the sternum; (b) to analyze the prevalence of the morphological variations and their relationship between sex and age; (c) to compare the results with other populations. The sterna of 155 skeletons from a Spanish population were studied. The age at the time of death was 17 to 97 years. We analyzed two metric and 22 sternal morphological variations described in the literature and designed an illustrated atlas. The atlas was validated using the intraclass correlation coefficient (ICC). A descriptive statistical analysis was conducted to measure the prevalence and relationship between sex and age. To analyze the interpopulation variability, we compared our results with those from other authors. The atlas with definitions and reference images improves the observation and detection of all morphological variations of the sternum (ICC = 0.90). The dependence between the morphological traits and sex was significant for the variations in the sternal angle, the number of esternebra, and the development of the xiphoid process. No significant differences were found between age group and morphological traits. The expression of the sternal morphological variation and sex are population-specific. The results will help standardize future studies and provide valuable information on the variability of the sternal morphological variation., (© 2021 American Association for Anatomy.)

Background: Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has proved effective in patients with cholecystitis at high surgical risk. The long-term risks of gallstone-related disease and stent-related adverse events are unknown., Methods: We performed a retrospective evaluation of a case series including subjects who underwent EUS-GBD using lumen-apposing metal stents (LAMS). Patients were identified from a prospective LAMS registry at a single tertiary center. Patients with a stent indwell time <1 year were excluded. Data regarding stent deployment and adverse events were retrieved from the prospective LAMS registry, while emergency room visits, admissions and causes of death were retrieved from electronic medical records., Results: We included 22 patients with a median age of 88.3 years (interquartile range [IQR]: 82.6-92.7), 14 (63.6%) were male. Median follow up was 24.4 months (IQR: 18.2-42.4) and median time to the last available imaging procedure was 607 days (IQR: 463-938). No LAMS-related adverse events were identified beyond the first year of follow up. During follow up, 12 patients (54.5%) visited the emergency room 34 times (1 visit/patient, IQR: 0-3) and a total of 36 hospital admissions were required, with a median of 1 admission/patient (IQR: 0-3). Fourteen (63.6%) patients died during follow up. Only 1 patient (4.5%) required new hospital admissions for gallstone-related disease., Conclusions: There were no adverse events beyond the first year after stent deployment, with only 4.5% of subjects requiring gallstone-related admissions. Permanent EUS-GBD with LAMS may be a definitive treatment for acute cholecystitis in patients ineligible for cholecystectomy., Competing Interests: Conflict of Interest: Raúl Torres Yuste, Javier García-Alonso, Ramón Sánchez-Ocana Hernández, Marta Cimavilla Román, Irene Peñas Herrero, Ana Yaiza Carbajo, Marina De Benito Sanz and Carlos De la Serna Higuera have no conflicts of interest or financial ties to disclose; Manuel Pérez-Miranda: Consultant: GI tech, Boston-Scientific, Gore.

We present a map and a data set containing information about intra-plate seismic sources in El Salvador. These are the results of the field campaigns and data analysis carried out by the research group of Planetary Geodinamics, Active Tectonics and Related Risks from Complutense University of Madrid during the last 12 years. We include two maps, the first map contains 1405 fault traces with evidences of Quaternary activity derived form morphometric, paleoseismological and geomorphological analysis together with field data mapping carried in El Salvador. The second map is a synthesis of the 29 intra-plate seismic sources selected from the quaternary faults map. The geometry of these sources was simplified and we also include a table where some available data of the proposed sources are included, such as their name, orientation, length and slip-rate. For further interpretation and discussion of these sources see (Alonso-Henar et al., 2018) [1, doi.org/10.1016/j.enggeo.2018.06.015].

We present BeechCOSTe52; a database of European beech (Fagus sylvatica) phenotypic measurements for several traits related to fitness measured in genetic trials planted across Europe. The dataset was compiled and harmonized during the COST-Action E52 (2006-2010), and subsequently cross-validated to ensure consistency of measurement data among trials and provenances. Phenotypic traits (height, diameter at breast height, basal diameter, mortality, phenology of spring bud burst and autumn-leaf discoloration) were recorded in 38 trial sites where 217 provenances covering the entire distribution of European beech were established in two consecutive series (1993/95 and 1996/98). The recorded data refer to 862,095 measurements of the same trees aged from 2 to 15 years old over multiple years. This dataset captures the considerable genetic and phenotypic intra-specific variation present in European beech and should be of interest to researchers from several disciplines including quantitative genetics, ecology, biogeography, macroecology, adaptive management of forests and bioeconomy.

The increasing demand which requires ascertaining the legal age of undocumented individuals who reach the various countries of the European Community means that new lines of research must be developed which help respond to questions posed by the Justice Administration. For this reason, this study has been designed on the basis of fusion times of the proximal humeral epiphysis. Moreover, the ultrasound scan has been used as the diagnostic method. It is a non-invasive technique, unlike the radiograph, which is used under current standards for the forensic diagnosis of age. Used as a study sample were the ultrasound images of the proximal humeral epiphysis among 221 individuals belonging to the Spanish population, of both genders, of ages ranging from 5 to 30 years. All of the images were classified into 6 stages of fusion based on the morphology of each. The results display differences among the six age groups proposed for each of the stages of fusion and are of great interest from the perspective of enforcing the Spanish Criminal Law Act on Minors, because Stage 4 would mean that the person being studied is under the age of 16 years in the case of males and 15 years in the case of females. These results, coupled with the use of ultrasound as a non-invasive diagnostic technique, make this study a very useful method when the use of radiographs is not possible.

Background: Population-based studies on the epidemiology of primary sclerosing cholangitis (PSC) are sparse., Aims: To investigate mortality and risk of cancer, and to identify risk factors for hepatobiliary cancer and the combined end-point liver related death or liver transplantation (OLT) in a population-based PSC cohort in Västra Götaland, Sweden., Methods: Primary sclerosing cholangitis cases were identified in diagnostic registries. Case validation and follow up was provided through individual review of case files and linkage to the Swedish Cancer and Cause of Death registries. Standardized mortality ratio (SMR) and standardized incidence ratio (SIR) for cancer were calculated in relation to the background population. Cox's proportional hazards analysis was used to calculate crude and adjusted relative risks (RRs)., Results: A total of 199 PSC patients were identified between 1992 and 2005. SMR in the PSC cohort was 4.20 (95% confidence interval (CI), 3.01-5.69). SIR for hepatobiliary cancer, cholangiocarcinoma and colorectal cancer were 177 (110-271), 868 (505-1390) and 2.87 (0.33-10.4) respectively. Age (RR=1.25 (1.01-1.53) per decade), female gender (RR=2.01 (1.09-3.72)), cholangitis (RR=2.56 (1.20-5.64)) and bilirubin (RR=3.95 (1.96-10.75) highest vs lowest quartile) were associated with the risk of liver related death or OLT. Age was associated with the risk of hepatobiliary cancer (RR 1.40 (1.01-1.95) per decade)., Conclusions: Primary sclerosing cholangitis was associated with a four-fold increase in mortality in this population-based study. In accordance with previous studies, the risk of hepatobiliary cancer was dramatically increased. However, the increased risk of colorectal cancer reported in previous studies could not be confirmed., (© 2011 John Wiley & Sons A/S.)

Objective: To analyze thoracic trauma assisted by the Emergency Service of Hospital da Irmandade da Santa Casa de Misericórdia de São Paulo., Methods: One hundred patients with thoracic trauma were assisted throughout six months in 2006. Data from their records were collected and a protocol of thoracic trauma was fulfilled. The Revised Trauma Score was used to evaluate gravity of injury and to calculate the survival index., Results: Prevalence of trauma injury in male from 20 to 29 years old was observed. Out of all patients, 44 had blunt trauma and 56 penetrating trauma (78.6% presented stab wounds and 21.4% gun shots). Up to the settings of injuries, 23% were in the thoracoabdominal transition, 7% in the precordium and 70% in the remainder thoracic area. In those with the thoracoabdominal transition injury, 22.7% were hemodynamically unstable and 77.3% stable. Thoracoabdominal injury patients presented 40.9% of diaphragm wound and all were stable. Of those with precordium wound, 37.5% presented cardiac injury. In cardiac onset, 66.7% presented stable and 33.3% unstable. Thoracic drainage was the most accomplished surgical procedure (71%)., Conclusions: The thoracic trauma patient is most prevalently young male with stab wound penetrating injury, without associated injuries, hemodynamically stable, presenting hemothorax, with high probability of survival.

Objective: Acute mastoiditis is a serious complication of acute otitis media, but it can be treated successfully in most of the cases with broad spectrum intravenous antibiotics and myringotomy. In the last 5 years we have perceived that there have been more complicated cases in the otic infectious pathology and the frequency was also higher., Methods: We reviewed the cases of mastoiditis in the last 10 years (1996-2005) in The Niño Jesús University Children Hospital in Madrid to confirm the clinic impression, the bacteriology, treatments and evolution of the children and analyze the causes of this clinic situation., Results: We have studied 215 cases of mastoiditis (0.6-17 years), 67.4% less than 3 years old and 69.3% males. The number of cases every year was the double since 1999 with the same percentage of admissions in the Pediatric service, and the triple in 2005. The percentage of surgical treatment grew from 4.3% to 33% in the last years and to 70% in 2005. Most cases (80%) have received prior antibacterial agent therapy, but individual pathogens and current complications of periostitis or subperiosteal abscess formation were equally distributed between the two groups. We have detected a 28.57% of Streptococcus pneumoniae and a significative high rate of Staphylococcus aureus (16.32%). A 53.68% of cases had negative cultures., Conclusions: There is a progressive increase in the incidence of acute mastoiditis in our medium, and an increase of the surgical treatments. Ten years ago the process was controlled with antibiotic therapy only, but now the number of interventions has been eight times the previous years. Most cases of acute mastoiditis have responded well to medical management alone. But if higher levels of resistance predominate, more severe forms of pneumococcal or other pathogen like S. aureus disease are likely to be seen, these would be less likely to respond to oral or parenteral antibiotic therapy, so, tympanocentesis for middle ear culture may become more valuable and more frequently used in cases of antibiotic treatment failures, and surgical therapy may be necessary more often in the future. Our hospital seems to be in this tendency now.

Introduction: it is known that in early-stage HIV-induced disease there is a discrepancy between the levels of viral burden and virus replication in peripheral blood versus lymphoid organs. HIV disease is active in the lymphoid tissue throughout the period of clinical latency. However, it is not known how long term progression of HIV infection is influenced by short-term changes in the adenoidal size., Objective: To assess the reliability of adenoidal-nasopharyngeal (AN) ratio in predicting clinical evolution of pediatric HIV infection., Methods: lateral radiographs of the nasopharynx in 94 Caucasian children born to HIV-1-infected mothers ranged from 6 months to 15 years (60 children infected with HIV-1 and 34 without HIV infection), and in a control group of 692 normal children were evaluated to obtain the AN ratio in order to identify the relationship of AN profiles with different stages of the disease. Patients were rated regarding their clinical and immunological status according to the Center for Disease Control Classification., Results: statistically significant differences between the groups of HIV-1-infected children, seroreverters and controls in the AN ratio were found (P < 0.001). Moreover, significant differences were also found in individual children that correlated with clinical progression., Conclusion: examination of radiographic changes in adenoidal size by AN ratio in relation to clinical status during one year period in the whole group showed strong prognostic value. These findings may have important implications in the design of therapeutic strategies.
