Ductal Adenocarcinoma of the Prostate with Novel Genetic Alterations Characterized by Next-Generation Sequencing.

Ductal adenocarcinoma of the prostate (DAP) is an uncommon variant of prostate cancer associated with aggressive disease and poor outcome. It presents most frequently as a mixed tumor combined with acinar adenocarcinoma. Although the histopathological features of DAP are well known, its genomic characteristics are still evolving, prompting the suggestion that all DAP would benefit from molecular analysis with the purpose of improving tumor recognition, genetic classification, and, ultimately, personalized therapy. Herein, we report a case of DAP with novel genetic alterations (BCOR P1153S, ERG M219I, KDR A750E, POLE S1896P, and RAD21 T461del).

Clinical practice guideline of the spanish society of oral surgery for oral surgery in patients with coagulation disorders / Guía de práctica clínica de la sociedad española de cirugía bucal para cirugía oral en pacientes con trastornos de la coagulación

Background: The number of patients treated with coagulation disorders, and more specifically with anticoagulanttherapy, has increased worldwide in recent years due to increased life expectancy in developed countries. Theprotocols for managing this type of patient in oral surgery has varied over recent years, especially after the appear-ance of new direct-acting oral anticoagulants (DOACs). The assessment of risk of bleeding in this type of patientwhen undergoing a surgical procedure continues to be a controversial issue for patients, dentists and general prac-titioners. The objective of this document is to offer recommendations, based on evidence, for decision making forpatients with coagulopathies who require dental surgical intervention. Material and Methods: Based on the indications of the “Preparation of Clinical Practice guidelines in the NationalHealth System. Methodological manual”, we gathered a group of experts who agreed on 15 PICO questions basedon managing patients with coagulation disorders in dental surgical procedures, such as fitting of implants or dentalextractions.Results: The 15 PICO questions were answered based on the available evidence, being limited in most cases due tothe lack of a control group. Two of the PICO questions were answered by the experts with a grade C recommendation,while the rest were answered with grade D.Conclusions: The results of this review highlight the need to undertake well designed clinical trials with controlgroups and with a representative sample size.(AU)

Age, period and cohort effects on gastric cancer mortality in Spain, 1980-2021.

BACKGROUND: this study aimed to evaluate the effects of age, time period and cohort (A-P-C) on gastric cancer (GC) mortality in Spain from 1980 to 2021. METHODS: an ecological trend study was performed (with aggregated data obtained from the Spanish National Statistics Institute (INE). Joinpoint regression software was used to estimate rates by sex and age group (< 35, 35-64, > 64 years) and mortality trends. The National Cancer Institute A-P-C tools were used to assess the effects of age, time of death and birth cohort. RESULTS: GC mortality rates in Spain decreased significantly in both sexes. In the under-35 age group, rates were stable after an initial significant decline. In the 35-64 age group, the decline was more pronounced in males than in females. In the 65+ age group, rates fell significantly for both sexes, but more so for females than for males. The net drift and local drift also showed significant decreases across all age groups from 24 years onwards. GC mortality rates increased with age and decreased with calendar time and successive birth cohorts, regardless of sex. The ratio of age-specific rates between males and females increased with age, and birth cohort relative risk estimates followed a steady downward trend until the mid-1970s, after which the decline stabilized. The relative risk decreased for both sexes, with a more pronounced decrease in males. CONCLUSION: GC mortality rates in Spain have been decreasing over time and across successive birth cohorts, with a stabilizing trend observed for those under 35 years of age.

Three double-dose reinforced hepatitis B revaccination scheme for patients with cirrhosis unresponsive to the standard regimen: an open-label randomised clinical trial.

OBJECTIVE: We aimed to compare the response rates between two different hepatitis B virus vaccination schedules for cirrhotic subjects who were non-responders to the first three 40 µg doses (month 0-1-2), and identify factors associated with the final response. DESIGN: A total of 120 cirrhotic patients (72.5% decompensated) were randomised at a 1:1 ratio to receive a single 40 µg booster vaccination at month 6 (classical arm) versus an additional round of three new 40 µg doses administered at monthly intervals (experimental arm). The main outcome was the rate of postvaccinal anti-hepatitis B surface antibodies levels ≥10 mIU/mL. RESULTS: Efficacy by ITT analysis was higher in the experimental arm (46.7%) than in the classical one (25%); OR 2.63, p=0.013. The experimental arm increased response rates compared with the classical one from 31% to 68% (OR 4.72; p=0.007), from 24.4% to 50% (OR 3.09; p=0.012) and from 24.4% to 53.8% (OR 3.62; p=0.007), in Child A, Model for End-Stage Liver Disease (MELD) <15 and MELD-Na<15 patients, respectively. Patients with more advanced liver disease did not benefit from the reinforced scheme. Both regimens showed similar safety profiles. Multivariable analysis showed that the experimental treatment was independently response associated when adjusted across three logistic regression models indicating equivalent cirrhosis severity. CONCLUSION: For cirrhotic patients, the revaccination of non-responders to the first three dose cycle, with three additional 40 µg doses, achieved significantly better response rates to those obtained with an isolated 40 µg booster dose. TRIAL REGISTRATION NUMBER: NCT01884415.

Importance of the vaporization margin during CO2 laser treatment of oral leukoplakia: A survival study.

OBJECTIVES: The main purpose of this study was to assess the response of oral leukoplakia to CO2 laser vaporization treatment, as well as determining possible factors that may affect recurrence of lesions. MATERIALS AND METHODS: A retrospective study was conducted, in which the medical records of patients who had been clinically and histologically diagnosed with oral leukoplakia and treated with CO2 laser between 1996 and 2019 at the Oral Medicine Teaching Unit of the Faculty of Dentistry of the University of Santiago de Compostela were reviewed. RESULTS: Fifty-eight patients were included: 36 female and 22 male subjects, with a mean age of 63.7 years old (SD ±13.1). The average follow-up time was 57.5 months (SD ±57.9). A relapse rate of 52.6% was determined. Of all the studied variables, the margin was the only one for which a statistically significant association with recurrence of lesions was demonstrated (p < 0.05). CONCLUSION: The vaporization of lesions using CO2 laser with a safety margin of at least 3 mm from the clinical limits of OL is a key factor in preventing recurrence.

Gender differences in perceived pain and health-related quality of life in people with chronic non-malignant pain: a cross-sectional study.

BACKGROUND: Chronic pain has a disproportionate impact on members of vulnerable population groups, and women are at substantially greater risk than men of suffering multiple chronic pain disorders. Moreover, one of the aspects most affected by the presence of chronic pain is that of health-related quality of life (HRQoL), worsening over time, as the disease persists. OBJECTIVES: To describe the profile of patients who suffer non-malignant chronic pain, from a gender perspective, and to identify factors related to their HRQoL and mental health. DESIGN: A cross-sectional study was carried out in patients with chronic non-cancer pain. METHODS: Sociodemographic variables, pain intensity at rest and in motion, SF-36 health questionnaire, anxiety, and depression were evaluated. RESULTS: The study population consisted of 531 subjects, of whom 64.2% were women. The mean age was 52.9 (SD: 10.4) years. The pain intensity recorded on the visual analogue scale was 6 (SD: 2.7) at rest and 8 (SD: 2) in motion. Physical component score and mental component score of quality of life were worse in women vs men: 33.73 (6.77) vs 32.33 (6.20), for the physical component; 36.89 (12.77) vs 32.91 (11.51), for mental component. Anxiety, depression and pain intensity, showed poorer results in women. CONCLUSION: Gender is a factor that should be considered in assessing and managing chronic pain, due to its influence on the perception of pain, and HRQoL. IMPACT STATEMENT: Gender is an important modifier of the perception of pain, and HRQoL. To achieve a patient-centred approach, nurses should incorporate gender as a differential factor to adapt and individualize pain management and patient education.

A new morphologic classification of the alveolar ridge after distraction osteogenesis in human patients. A 17 years retrospective case series study / Una nueva clasificación morfológica de la cresta alveolar después de la distracción osteogénesis en pacientes humanos. Un estudio de serie de casos retrospectivo de 17 años

Background: To perform a morphologic classification based on the results of bone augmentation after a distractionosteogenesis.Material and Methods: Thirty-four (34) patients (24 women and 10 men; mean age, 47.1 years (SD=9.5); age range,23 to 62 years) underwent a total of 42 alveolar ridge distractions before the placement of a total of 89 dentalimplants. Ridge bone morphology was evaluated as the main ordinal variable. Chi-squared, Kruskal-Wallis andANOVA one-way test were used.Results: Category I (30.95%): consisted of wide alveolar rim and no bone defects Category II (28.57%): widealveolar rim, lateral bone surface concavity. Category III (23.81%): narrow alveolar rim, lateral bone surface con-cavity. Category IV (2.38 %): distraction transport segment forming a bridge, without bone formed beneath andrequiring guided bone regeneration. Category V (9.52%): return of the transport segment to its initial position dueto the reverse rotation of the distractor screw. Category VI (4.76 %): distraction transport segment completely lost.Subcategory D (28.57%), consisted of lingual deviation of the distraction axis, occurring in any of the categories Ito IV. More men (76.9 %) presented with category I (p<0.001). The use of the chisel resulted mainly in categories I and II (69.4 %) (p<0.001). GBR was only required in 23.1 % of the cases in Category I (p=0.011). The bone heightachieved decreases as the category increases, due to the accompanying osteogenic limitations (p<0.001). The im-plants placed in category I were longer 11.5 ± 0.9 mm (CI95% 10.9-11.9 mm) compared to those placed in categoryIII with a length of 10.4 ± 1.5 mm (CI95% 9.5-11.4 mm) (p=0.035).Conclusions: The alveolar ridge after distraction osteogenesis could be divided into six morphologic categorieswhich provide a useful basis for decision-making regarding implant placement.(AU)

Effect of a Preventive Oral Health Program Starting during Pregnancy: A Case-Control Study Comparing Immigrant and Native Women and Their Children.

The objective was to evaluate whether including pregnant women in a preventive dental program prevented the appearance of caries in their children up to the age of 6, and whether the effect was similar in children of immigrant and non-immigrant women. In phase I, 90 pregnant women, 45 immigrants and 45 natives, were taught about the development and prevention of caries. In phase II the oral health of their children at the age of 6 (n = 90) was evaluated, along with a control group of children of natives and immigrants of the same age (n = 90). A survey was used to determine participants' backgrounds and habits. A multivariate study of the results was performed using R-core software. The number of children without caries was 128 (71.1%), whereas 52 (28.9%) had caries, 15 from the protocol (16.67%) and 37 from the control group (41.11%), with statistically significant differences (p < 0.001). The mean number of caries for the children in the protocol was 0.62 ± 2 and in the control group it was 1.88 ± 2.9 (p = 0.001). In the multivariate analysis the risk of developing caries was higher for the condition of being the child of an immigrant (OR = 11.137), inadequate oral health (OR = 4.993), the children being overweight at the age of 6 (OR = 10.680), and the consumption of candies (OR = 5.042). In conclusion, the preventive protocols started during pregnancy reduced caries in participants' children, which suggests that these protocols should be encouraged. Because immigrant children are more vulnerable to caries, they and their parents should be included in preventive programs once they arrive in the host country.

Efficacy of different formulations of nystatin in an experimental model of oral candidiasis in sialoadenectomized rats.

BACKGROUND/PURPOSE: Oral candidiasis is the most common fungal infection of the oral cavity and has become a focus of attention in recent years because of its association with highly topical immunosuppressive conditions. The aims of this study were to determine the value of microbiological, clinical and histological parameters of Candida albicans colonisation of the dorsal tongue surface as indicators of disease severity, and to evaluate therapeutic response to different formulations of nystatin. MATERIALS AND METHODS: We used 84 males, 2-month-old Sprague-Dawley sialoadenectomized rats. Different formulations of nystatin were used to evaluate the therapeutic response. The animals were randomized to 2 groups with each of 42 animals and received the experimental treatments from day 17-22. RESULTS: 100% of the rats showed evidence of infection. At 5 and 10 days of starting treatment with nystatin + chitosan, and at 10 days of starting nystatin + orabase, the number of animals with positive dorsal tongue culture decreased significantly (p < 0.05), acting the Nystatin + chitosan more rapidly against Candida. In the control group, the percentage of normal papillae on day 22 and 27 was 83.33% (SD = 1.50) and 79.08% (SD = 2.30), respectively. Significant differences were observed in the mean O'Grady score at 5 and 10 days (p < 0.0001). CONCLUSION: The model has been shown to be effective in inducing infection, and that the combination of nystatin and chitosan yielded the best therapeutic outcomes at both 5 and 10 days after infection.

Impact of a nurse-led intervention on quality of life in patients with chronic non-malignant pain: An open randomized controlled trial.

AIMS: To determine the effect of a comprehensive nurse-led programme for patients with chronic non-malignant pain, on quality of life, level of pain, anxiety, and depression, as primary outcomes and patients' satisfaction as a secondary end point. DESIGN: An open-label randomized controlled trial was carried out. METHODS: The experimental group received both a nurse-led intervention on healthy lifestyles, education on self-esteem, pain awareness, communication, and relaxation techniques. The control group received usual care. Quality of life, level of pain, anxiety, and depression were the main outcomes. Data were obtained at baseline, immediately after the intervention, and 6 and 9 months. The study was carried out from 2015-2017. RESULTS: The sample was composed of 279 patients. At 9 months, the effect size (non-parametric effect size statistic A) favoured the intervention group for SF-36 mental health score (A = 0.79; 95% CI: 0.73-0.85), anxiety (A = 0.58; 95% CI: 0.51-0.65), pain intensity (A = 0.57; 95% CI: 0.51-0.64), and depression (A = 0.58; 95% CI: 0.51-0.65). Smaller differences were found on physical scores between the intervention and the usual care group. Patients showed a high level of satisfaction with the introduced intervention. CONCLUSION: A comprehensive nurse-led programme for patients with chronic non-malignant pain has a positive impact on their quality of life, level of pain, and mental health. IMPACT: Studies have reported that the problem of chronic pain is not optimally controlled. A structured nurse-led programme has been tested to facilitate healthy behaviours to help patients manage their chronic pain and to provide them with the necessary tools for their self-care. This nurse-led intervention improved their mental health and decreased their level of pain.

Characterization of Birdwatching Demand Using a Logit Approach: Comparative Analysis of Source Markets (National vs Foreign).

Birdwatching is a tourism activity that relates closely to protected natural spaces and that helps contribute to the balance between economic, social and environmental aspects of sustainability. In some European countries (the United Kingdom, Germany, Holland), this recreational activity has a large number of followers, making it a new segment of tourist demand with great possibilities for growth. The objective of this study is to identify the main characteristics of the demand for birdwatching in one of the European territories having a high resource supply, as is the case with Extremadura (Spain). To do this, a logit modelization has been proposed in order to estimate the probability of going birdwatching in the region, based on a random sample of over 3000 tourists that visited the region in 2017. This characterization of birdwatching demand was carried out using variables such as gender, age, type of travel, type of lodging, and assessment of tourism services. Given that the national and the foreign demand of this tourism modality may present distinct behaviors, and therefore, specific characterizations, a structural change test (Chow test) was also conducted in order to determine to what extent these two segments of demand, based on the source markets, have (or do not have) distinguishing features.

Determinación serológica en el seguimiento de la vacunación triple vírica, varicela y hepa-titis B, en estudiantes de enfermería que hacen prácticas en el Complejo Asistencial de Zamora / Serological determination in the follow-up of the triple virus vaccination, chickenpox and hepatitis b, in nursing students who practice at the Zamora healthcare complex

INTRODUCCIÓN Y OBJETIVOS: Garantizar la seguridad y salud de los estudiantes de enfermería que realizan prácticas en el hospital ofreciéndoles vacunación hasta alcanzar el nivel inmunológico de protección necesario. METODOLOGÍA: Revisión y recogida de datos de las historias clínico-laborales de 182 estudiantes de la Escuela de Enfermería de Sacyl en Zamora (2016-2019). RESULTADOS: Todos acreditan estar vacunados según calendario oficial. Tras primera serología, el 31,6% no presenta inmunidad frente a la triple vírica, el 2,15% frente a la varicela y el 86,9% frente a la vacuna de la hepatitis B. El 7,1% resultó no respondedor frente a la vacuna de la hepatitis B tras segunda pauta vacunal completa. CONCLUSIONES: La realización de la serología en el cribado prevacunación permite revacunar a aquellos que no presentan inmunización así como detectar aquellos casos no respondedores que tendrán un manejo adecuado si ocurre un accidente con exposición a una fuente de alto riesgo

INTRODUCTION AND OBJETIVES: Ensure the safety and health of nursing students who practice in the hospital by providing them with vaccinations up to the necessary immune protection level. METHODOLOGY: Review and data collection from the clinical- workplace histories of 182 students of the Sacyl School of Nursing in Zamora (2016-2019). RESULTS: All of them certify to be vaccinated according to official calendar. After the first serology, 31.6% did not have immunity against the triple virus, 2.15% against chickenpox and 86.9% against the hepatitis B vaccine. 7.1% were not responding to the hepatitis B vaccine after the second complete vaccination. CONCLUSION: The realization of serology in the screening allows to revaccinate those who don't present immunization, as well as detect those non-responders who will have adequate management if an accident with exposure to a high-risk source occurs

Coercivity and Magnetic Anisotropy of (Fe0.76Si0.09B0.10P0.05)97.5Nb2.0Cu0.5 Amorphous and Nanocrystalline Alloy Produced by Gas Atomization Process.

We present the evolution of magnetic anisotropy obtained from the magnetization curve of (Fe0.76Si0.09B0.10P0.05)97.5Nb2.0Cu0.5 amorphous and nanocrystalline alloy produced by a gas atomization process. The material obtained by this process is a powder exhibiting amorphous character in the as-atomized state. Heat treatment at 480 °C provokes structural relaxation, while annealing the powder at 530 °C for 30 and 60 min develops a fine nanocrystalline structure. Magnetic anisotropy distribution is explained by considering dipolar effects and the modified random anisotropy model.

An acute exposure to perfluorooctanoic acid causes non-reversible plasma membrane injury in HeLa cells.

Health and environmental risks regarding perfluorooctanoic acid, a well-known perfluorinated compound, are still a subject of great concern. Ubiquitous exposure and disparity of results make it difficult to determine the underlying mechanism of action, especially at the cellular level. This study proposes an experimental design to assess the reversibility of adverse effects after a one-time exposure to the compound, in comparison with other more conventional timings. Complementary endpoints including total protein content, neutral red uptake and MTT reduction tests along with division rates and microscopic observations were evaluated in HeLa cells. In addition, PFOA quantification inside the cells was performed. The cellular effects exerted after 24 h exposure to perfluorooctanoic acid are non-reversible after a 48 h recovery period. In addition, we describe for the first time the induction of plasma membrane blebbing and the activation of membrane repair mechanisms after recovery from non-cytotoxic treatments with the compound. This experimental design has provided relevant information regarding the toxicity of this perfluorinated compound, relating all the adverse effects detected to its interaction with the plasma membrane.

Oral hygiene instructions and professional control as part of the treatment of desquamative gingivitis. Systematic review

Background: The aim of this present article was to evaluate the scientific evidence on the efficacy of daily hygiene and professional prophylaxis for treatment of desquamative gingivitis. Material and Methods: The present systematic review was conducted following the PRISMA protocol. Searches were carried out in Pubmed, Embase, Web of Science and Cochrane Library up to July 2018, randomized clinical trials and cohort studies on desquamative gingivitis (DG), and oral diseases joined to DG. Results: After screening, we found that nine publications met the eligibility criteria eight cohort studies and one randomized control trial. The diagnosis of the diseases corresponded to oral lichen planus (n=185), mucous membrane pemphigoid (n=13); plasma cell gingivitits (n=15) and pemphigus vulgar (n=11). The follow-up was between a week and a year after instructing patients. Dental daily hygiene and professional prophylaxis, at least with supragingival scaling and polishing have significantly improved the extension of the lesion and reduced the activity of DG, and gingival bleeding in all patients. Furthermore, these techniques have also reduced pain and gingival plaque. Conclusions: In conclusion the studies presented support the efficacy of maintaining personal and professional oral hygiene in patients with GD, reducing the clinical signs of the disease, regardless of its pathogenesis

20 years of alveolar distraction: A systematic review of the literature

BACKGROUND: The Vertical Alveolar Distraction Osteogenesis (VADO) technique is an excellent solution for bone and soft tissue neoformation in areas in which there has been significant bone atrophy that hinders normal rehabilitation using dental implants. The goal of this systematic review is to analyze the most relevant articles published on VADO in the literature over the past 20 years. MATERIAL AND METHODS: The review was performed by using the keywords: "alveolar ridge", "distraction ostegenesis" and "dental implant". This search produced a total result of 240 articles. The clinical studies and cases reported in humans amounted to 113 articles, 18 articles referred to studies developed on animals and 33 review articles. The presentation of this systematic analysis follows the criteria described in the PRISMA declaration. RESULTS: 22 articles complied with the inclusion criteria and 7 articles more were added manually, reaching a total sample of 29 studies. Following the analysis of the studies, they were classified into 18 high-quality, 10 mediumquality and 1 low-quality study. Only 4 studies achieved a maximum score of 9 (according to NewCastle Ottawa Scale, NOS). CONCLUSIONS: VADO is a technique with greater potential in vertical gain. The performance of dental implants has a success and survival rate similar to dental implants placed on bones that are not subject to increase techniques
