Mutational spectrum of GNAL, THAP1 and TOR1A genes in isolated dystonia: study in a population from Spain and systematic literature review

[Objective] We aimed to investigate the prevalence of TOR1A, GNAL and THAP1 variants as the cause of dystonia in a cohort of Spanish patients with isolated dystonia and in the literature.[Methods] A population of 2028 subjects (including 1053 patients with different subtypes of isolated dystonia and 975 healthy controls) from southern and central Spain was included. The genes TOR1A, THAP1 and GNAL were screened using a combination of high-resolution melting analysis and direct DNA resequencing. In addition, an extensive literature search to identify original articles (published before 10 August 2020) reporting mutations in TOR1A, THAP1 or GNAL associated to dystonia was performed.[Results] Pathogenic or likely pathogenic variants in TOR1A, THAP1 and GNAL were identified in 0.48%, 0.57% and 0.29% of our patients, respectively. Five patients carried the variation p.Glu303del in TOR1A. A very rare variant in GNAL (p.Ser238Asn) was found as a putative risk factor for dystonia. In the literature, variations in TOR1A, THAP1 and GNAL accounted for about 6%, 1.8% and 1.1% of published dystonia patients, respectively.[Conclusions] There is a different genetic contribution to dystonia of these three genes in our patients (about 1.3% of patients) and in the literature (about 3.6% of patients), probably due the high proportion of adult-onset cases in our cohort. As regards age at onset, site of dystonia onset, and final distribution, in our population there is a clear differentiation between DYT-TOR1A and DYT-GNAL, with DYT-THAP1 likely to be an intermediate phenotype.This work was supported by the Carlos III Health Institute-European Regional Development Fund (ISCIII-FEDER) [PI14/01823, PI16/01575, PI18/01898, PI19/01576], the Andalusian Regional Ministry of Economics, Innovation, Science and Employment [CVI-02526, CTS-7685], the Andalusian Regional Ministry of Health and Welfare [PI-0741-2010, PI-0471-2013, PE-0210-2018, PI-0459-2018, PE-0186-2019], and the Alicia Koplowitz and Mutua Madrileña Foundations.

Municipal mortality due to thyroid cancer in Spain

BACKGROUND: Thyroid cancer is a tumor with a low but growing incidence in Spain. This study sought to depict its spatial municipal mortality pattern, using the classic model proposed by Besag, York and Mollié. METHODS: It was possible to compile and ascertain the posterior distribution of relative risk on the basis of a single Bayesian spatial model covering all of Spain's 8077 municipal areas. Maps were plotted depicting standardized mortality ratios, smoothed relative risk (RR) estimates, and the posterior probability that RR > 1. RESULTS: From 1989 to 1998 a total of 2,538 thyroid cancer deaths were registered in 1,041 municipalities. The highest relative risks were mostly situated in the Canary Islands, the province of Lugo, the east of La Coruña (Corunna) and western areas of Asturias and Orense. CONCLUSION: The observed mortality pattern coincides with areas in Spain where goiter has been declared endemic. The higher frequency in these same areas of undifferentiated, more aggressive carcinomas could be reflected in the mortality figures. Other unknown genetic or environmental factors could also play a role in the etiology of this tumor

Second GHEP-ISFG exercise for DVI: “DNA-led” victims’ identification in a simulated air crash

The Spanish and Portuguese-Speaking Working Group of the International Society for Forensic Genetics (GHEP-ISFG) has organized a second collaborative exercise on a simulated case of Disaster Victim Identification (DVI), with the participation of eighteen laboratories. The exercise focused on the analysis of a simulated plane crash case of medium-size resulting in 66 victims with varying degrees of fragmentation of the bodies (with commingled remains). As an additional difficulty, this second exercise included 21 related victims belonging to 6 families among the 66 missings to be identified. A total number of 228 post-mortem samples were represented with aSTR and mtDNA profiles, with a proportion of partial aSTR profiles simulating charred remains. To perform the exercise, participants were provided with aSTR and mtDNA data of 51 reference pedigrees —some of which deficient—including 128 donors for identification purposes. The exercise consisted firstly in the comparison of the post-mortem genetic profiles in order to re-associate fragmented remains to the same individual and secondly in the identification of the re-associated remains by comparing aSTR and mtDNA profiles with reference pedigrees using pre-established thresholds to report a positive identification. Regarding the results of the post-mortem samples re-associations, only a small number of discrepancies among participants were detected, all of which were from just a few labs. However, in the identification process by kinship analysis with family references, there were more discrepancies in comparison to the correct results. The identification results of single victims yielded fewer problems than the identification of multiple related victims within the same family groups. Several reasons for the discrepant results were detected: a) the identity/non-identity hypotheses were sometimes wrongly expressed in the likelihood ratio calculations, b) some laboratories failed to use all family references to report the DNA match, c) In families with several related victims, some laboratories firstly identified some victims and then unnecessarily used their genetic information to identify the remaining victims within the family, d) some laboratories did not correctly use “prior odds” values for the Bayesian treatment of the episode for both post-mortem/post-mortem re-associations as well as the ante-mortem/post-mortem comparisons to evaluate the probability of identity. For some of the above reasons, certain laboratories failed to identify some victims. This simulated “DNA-led” identification exercise may help forensic genetic laboratories to gain experience and expertize for DVI or MPI in using genetic data and comparing their own results with the ones in this collaborative exercise.This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.Peer reviewe

Evaluation of appendicitis risk prediction models in adults with suspected appendicitis

Background Appendicitis is the most common general surgical emergency worldwide, but its diagnosis remains challenging. The aim of this study was to determine whether existing risk prediction models can reliably identify patients presenting to hospital in the UK with acute right iliac fossa (RIF) pain who are at low risk of appendicitis. Methods A systematic search was completed to identify all existing appendicitis risk prediction models. Models were validated using UK data from an international prospective cohort study that captured consecutive patients aged 16–45 years presenting to hospital with acute RIF in March to June 2017. The main outcome was best achievable model specificity (proportion of patients who did not have appendicitis correctly classified as low risk) whilst maintaining a failure rate below 5 per cent (proportion of patients identified as low risk who actually had appendicitis). Results Some 5345 patients across 154 UK hospitals were identified, of which two‐thirds (3613 of 5345, 67·6 per cent) were women. Women were more than twice as likely to undergo surgery with removal of a histologically normal appendix (272 of 964, 28·2 per cent) than men (120 of 993, 12·1 per cent) (relative risk 2·33, 95 per cent c.i. 1·92 to 2·84; P < 0·001). Of 15 validated risk prediction models, the Adult Appendicitis Score performed best (cut‐off score 8 or less, specificity 63·1 per cent, failure rate 3·7 per cent). The Appendicitis Inflammatory Response Score performed best for men (cut‐off score 2 or less, specificity 24·7 per cent, failure rate 2·4 per cent). Conclusion Women in the UK had a disproportionate risk of admission without surgical intervention and had high rates of normal appendicectomy. Risk prediction models to support shared decision‐making by identifying adults in the UK at low risk of appendicitis were identified

Evaluation of Sensory and Microbiological Changes and Identification of Proteolytic Bacteria during the Iced Storage of Farmed Turbot (Psetta maxima)

8 pages, 5 tables, 2 figuresSensory and quantitative microbiological analyses were performed in farmed turbot (Psetta maxima) during iced storage. Sensory analyses revealed a shelf life of 19 d for farmed turbot. The production of total volatile base nitrogen (TVB-N) and trimethylamine-nitrogen (TMA-N) was low and reached levels close to 40 mg TVB-N/ 100 g muscle and 3.5 mg /TMA-N/100 g muscle, even after 40 d of refrigerated storage. The pH value of turbot muscle increased from an initial value of 6.3 to close to 7.0 after 29 d of iced storage. Microbial growth was slow in iced turbot: total aerobic counts reached levels below 7 log colony forming units/g units even after 40 d of storage. Lactic acid bacteria—mainly Lactobacillus delbrueckii subsp. delbrueckii and Lactococcus lactis subsp. lactis strains—were predominant among the proteolytic strains isolated from iced turbot. Proteolytic strains of L. lactis subsp. lactis, Brochothrix thermosphacta, Plesiomonas shigelloides, Proteus vulgaris, and Pantoea species were also isolated from temperature-abused turbot, such proteolytic strains being predominant with respect to nonpro-teolytic microorganisms, suggesting a preferential role of such proteolytic bacteria in the spoilage of turbot. The slow bacterial growth, together with the relative predominance of lactic acid bacteria over Gram-negative microorganisms, may be related to the extraordinary maintenance of the quality and extended shelf life of farmed turbotThis investigation was funded by a project granted by the Secretaría Xeral de Investigación e Desenvolvemento of the Xunta deGalicia (Project PGIDT01MAR40202PR)Peer reviewe

Capnography is superior to pulse oximetry for the detection of respiratory depression during colonoscopy La capnografía es superior a la pulsioximetría en la detección de depresión respiratoria durante las colonoscopias

Background: pulse oximetry is a widely accepted procedure for ventilatory monitoring during gastrointestinal endoscopy, but this method provides an indirect measurement of the respiratory function. In addition, detection of abnormal ventilatory activity can be delayed, especially if supplemental oxygen is provided. Capnography offers continuous real-time measurement of expiratory carbon dioxide. Objective: we aimed at prospectively examining the advantages of capnography over the standard pulse oximetry monitoring during sedated colonoscopies. Patients and methods:fifty patients undergoing colonoscopy were simultaneously monitored with pulse oximetry and capnography by using two different devices in each patient. Several sedation regimens were administered. Episodes of apnea or hypoventilation detected by capnography were compared with the occurrence of hypoxemia. Results: twenty-nine episodes of disordered respiration occurred in 16 patients (mean duration 54.4 seconds). Only 38% of apnea or hypoventilation episodes were detected by pulse oximetry. A mean delay of 38.6 seconds was observed in the events detected by pulse oximetry (two episodes of disturbed ventilation were simultaneously detected by capnography and pulse oximetry). Conclusions: apnea or hypoventilation commonly occurs during colonoscopy with sedation. Capnography is more reliable than pulse oximetry in early detection of respiratory depression in this setting

Sistema masculino transobturador ajustable (ATOMS) como tratamiento de la incontinencia urinaria de esfuerzo secundaria a reseccion transuretral de la prostata

OBJECTIVES: Feasibility study to evaluate efficacy and safety of Adjustable Transobturator Male System (ATOMS) for male stress urinary incontinence (SUI) after transurethral resection of the prostate. MATERIALS AND METHODS: Twenty patients were implanted ATOMS for SUI caused by transurethral resection of the prostate with or without radiotherapy. Incontinence severity was evaluated as mild (2 pads/day), moderate (3-5 pads/day) or severe (≥6pads/day), and dryness as none or one security pad/day. Changes in pad-test and pad-count after adjustment were investigated, together with operative parameters, patient satisfaction with the procedure, and number and grade of complications (Clavien-Dindo). RESULTS: Median age was 76.5years. Five patients received previous pelvic radiation (3 prostate, 2 rectal cancer) and 2 (10%) previous failed artificial urinary sphincter with urethral erosion and mechanical failure, respectively. Preoperative SUI was mild in 4 (20%), moderate in 7 (35%) and severe in 9 (45%). Median filling of the system was 13.5ml. Median pad-test decreased from 375±855ml baseline to 10±31.5ml and pad-count from 4±3 to 0±1.5 after adjustment (1±3fillings). Postoperative SUI distribution was mild in 2 (10%), moderate in one (5%) and severe in 2 (10%). Satisfaction rate was 80%, equal for transurethral resection of the prostate with/without previous radiotherapy. No patient had urinary retention after catheter removal. Complications presented in 3 (15%) patients, all minor. After median 38.5mo follow-up no system has been removed, 19 (95%) self-considered better than before and 11 (55%) very much better. CONCLUSION: Based on short-term efficacy and patient satisfaction ATOMS can be considered a realistic alternative for SUI after transurethral resection of the prostate, even after irradiation. Absence of urethral erosion and very limited problems make this alternative especially attractive for cases with diminished dexterity, advanced age and previous failed treatments.Sin financiación1.136 JCR (2018) Q4, 68/80 Urology & Nephrology0.332 SJR (2018) Q3, 66/107 UrologyNo data IDR 2018UE

Mapa de suelos de España. Península y Baleares. Escala 1/1.000.000. Descripción de las asociaciones y tipos principales de suelos

126 páginas, descripción de 40 perfiles.El estudio de los suelos desde un punto de vista científico, es relativamente reciente en Espana. Los trabajos de Huguet del Villar, que se concretaron en una publicación y un mapa de suelos a escala 1:1.000.000, fueron, quizás, el primer intento serio de estudio general de suelos de nuestra nación. Posteriormente y a partir de 1940 se comenzó un período inicial y eficaz en el estudio de los suelos, que se intensificó con la creación del Instituto de Edafología bajo la dirección del gran maestro José María Albareda, a cuyo entusiasmo, saber y dedicación se debe la espléndida realidad que hoy ha cuajado en la publicación de este Mapa de Suelos 1:1.000.000 y la memoria que le acompaña.Peer reviewe
