Enlarged vestibular aqueduct as a cause of postneonatal deafness.

INTRODUCTION: The enlarged vestibular aqueduct (EVA) is the most frequent malformation of the inner ear associated with sensorineural hearing loss (5-15%). It exists when the diameter in imaging tests is greater than 1.5 mm at its midpoint. The association between hearing loss and EVA has been described in a syndromic and non-syndromic manner. It can appear as a familial or isolated form and the audiological profile is highly variable. The gene responsible for sensorineural hearing loss associated with EVA is located in the same region described for Pendred syndrome, where the SCL26A4 gene is located. OBJECTIVE: To describe a series of children diagnosed with EVA in order to study their clinical and audiological characteristics, as well as the associated genetic and vestibular alterations. METHOD: Retrospective study of data collection of children diagnosed with EVA, from April 2014 to February 2023. RESULTS: Of the 17 cases, 12 were male and 5 were female. 5 of them were unilateral and 12 bilateral. In 5 cases, a cranial traumatism triggered the hearing loss. Genetic alterations were detected in 3 cases: 2 mutations in the SCL26A4 gene and 1 mutation in the MCT1 gene. 13 patients (76.5%) were rehabilitated with hearing aids and 9 of them required cochlear implantation. DISCUSSION: The clinical importance of AVD lies in the fact that it is a frequent finding in the context of postneonatal hearing loss. It is convenient to have a high suspicion to diagnose it with imaging tests, to monitor its evolution, and to rehabilitate early.

Cribado auditivo neonatal universal e hipoacusia diferida o de desarrollo tardío / Universal neonatal hearing screening and delayed hearing loss or late-developmental hearing loss

Objetivo Determinar el porcentaje de niños que presentan una hipoacusia bilateral permanente posnatal para estudiar su incidencia, los factores de riesgo relacionados, su diagnóstico y su tratamiento.MétodosEstudio retrospectivo de recogida de datos de niños diagnosticados de hipoacusia fuera del periodo neonatal en la Unidad de Hipoacusia del Hospital Universitario Central de Asturias, desde abril de 2014 hasta abril de 2021.ResultadosUn total de 52 casos cumplieron los criterios de inclusión. La tasa de detección de hipoacusias congénitas del programa de cribado neonatal en el mismo periodo de estudio fue de 1,5 niños por cada 1000 recién nacidos al año; sumando las hipoacusias posnatales da como resultado una tasa de hipoacusia bilateral infantil de 2,7 niños por 1000 (55,5% y 44,4%, respectivamente). Presentan factores de riesgo de hipoacusia 35, siendo 23 de riesgo retrococlear. La edad media de la derivación fue de 91,9 meses (18-185). La adaptación audioprotésica se indicó en 44 casos (84,6%). En 8 casos (15,4%) se indicó la implantación coclear.DiscusiónAunque la hipoacusia congénita representa la mayoría de las sorderas en la infancia, la hipoacusia posnatal tiene una incidencia importante. Esta puede responder principalmente a: 1) que el deterioro auditivo puede surgir en los primeros años de vida, 2) que la hipoacusia leve, así como las pérdidas auditivas en frecuencias graves son indetectables por el cribado neonatal en algunos casos, 3) que algunos niños pueden presentar falsos negativos en los resultados.ConclusiónLa hipoacusia posnatal requiere la identificación de factores de riesgo y el seguimiento a largo plazo de los niños que la sufren, ya que es preciso que sea detectada y tratada precozmente.

Objective To determine the percentage of children with permanent bilateral postnatal hearing loss in order to study its incidence, related risk factors, diagnosis and treatment.MethodsRetrospective study to collect data on children diagnosed with hearing loss outside the neonatal period in the Hearing Loss Unit of the Hospital Universitario Central de Asturias, from April 2014 to April 2021.Results52 cases met the inclusion criteria. The detection rate of congenital hearing loss in the neonatal screening programme in the same study period was 1.5 children per thousand newborns per year, adding postnatal hearing loss results in a rate of infant bilateral hearing loss of 2.7 children per thousand (55.5% and 44.4% respectively). Thirty-five children presented risk factors for hearing loss, of which 23 were at retrocochlear risk. The mean age at referral was 91.9 (18-185) months. Hearing aid fitting was indicated in 44 cases (84.6%). Cochlear implantation was indicated in eight cases (15.4%).DiscussionAlthough congenital hearing loss accounts for the majority of childhood deafness, postnatal hearing loss has a significant incidence. This may be mainly due to: 1) that hearing impairment may arise in the first years of life, 2) that mild hearing loss as well as hearing loss in severe frequencies are undetectable by neonatal screening in some cases, 3) that some children may have false negative results.ConclusionPostnatal hearing loss requires identification of risk factors and long-term follow-up of children with hearing loss, as it needs to be detected and treated early.

Elimination of hepatitis C virus in a prison: An 18-year experience.

INTRODUCTION: Despite the decrease of hepatitis C in Spanish prisons in the last years, it still remains a reservoir for infection. The aim of this work is to analyze the characteristics of these patients and the response to antiviral treatment over the last 18 years. METHODS: Retrospective observational study in inmates of Araba penitentiary center diagnosed with HCV infection between 2002 and 2020. A descriptive analysis of patient characteristics and the response to the three antiviral treatment modalities was performed: peg-interferon and ribavirin, peg-interferon, ribavirin and a first-generation protease inhibitor and different combinations of direct-acting antivirals. RESULTS: A total of 248 antiviral treatments were prescribed. Treatment response rate up to 2015 was 65% and 93,7% after that year. Interferon non-responders were the main cause of non-response to treatment in periods 1 and 2 (40%-50%). Conversely, in period 3 viral breakthrough (67%) was the main culprit. CONCLUSION: After 18 years, active hepatitis C infection in prison inmates has resolved with treatment according to clinical criteria. Therefore, the stay in prison may represent an opportunity to reduce the reservoir of the disease in the community, together with continued health care for those released from prison.

SARS-CoV-2 transmission in teenagers and young adults in Fútbol Club Barcelona's Multidisciplinary Sports Training Academy.

Most studies, aimed at determining the incidence and transmission of SARS-CoV-2 in children and teenagers, have been developed in school settings. Our study conducted surveillance and inferred attack rates focusing on the practice of sports. Prospective and observational study of those attending the sports facilities of Fútbol Club Barcelona (FCB), in Barcelona, Spain, throughout the 2020-2021 season. Participants were young players (from five different sports) and adult workers, who belonged to stable teams (shared routines and were involved in same quarantine rules). Biweekly health questionnaires and SARS-CoV-2 screening were conducted. From the 234 participants included, 70 (30%) both lived and trained in the FCB facilities (Recruitment Pathway 1;RP1) and 164 (70%) lived at their own household and just came to the facilities to train (RP2). During the study, 38 positive cases were identified; none had severe symptoms or needed hospitalization. The overall weekly incidence in the cohorts did not differ compared to the one expected in the community, except for 2 weeks when an outbreak occurred. The attack rate (AR) was three times higher for the participants from RP1, in comparison to those from RP2 (p < 0.01). A Basketball team showed a significant higher AR.  Conclusion: Physical activities in stable teams are not related to an increased risk of transmission of SARS-CoV-2, since there were the same observed cases than expected in the community. The risk is higher in indoor sports (Basketball vs. Football), and in closed cohort living settings (RP1 vs. RP2). The fulfilment of preventive measures is essential. What is Known: • Despite the low numerical impact caused in paediatric hospitalizations during COVID-19 pandemic, the social impact has been maximum. • The transmission potential in children and teenagers is limited, and it had been widely demonstrated in school settings. What is New: • Group physical activities in children and teenagers are not also related to an increased risk of transmission of SARS-CoV-2, when preventive measures, such as washing hands, and screening protocols are applied. • Routine and semi-professional sports activities seem safe environments to promote during this pandemic.

Anterior Cingulate Cortex Signals the Need to Control Intrusive Thoughts during Motivated Forgetting.

How do people limit awareness of unwanted memories? When such memories intrude, a control process engages the right DLPFC (rDLPFC) to inhibit hippocampal activity and stop retrieval. It remains unknown how the need for control is detected, and whether control operates proactively to prevent unwelcome memories from being retrieved, or responds reactively, to counteract intrusions. We hypothesized that dorsal ACC (dACC) detects the emergence of an unwanted trace in awareness and transmits the need for inhibitory control to rDLPFC. During a memory suppression task, we measured in humans (both sexes) trial-by-trial variations in the theta power and N2 amplitude of dACC, two EEG markers that are thought to reflect the need for control. With simultaneous EEG-fMRI recordings, we tracked interactions among dACC, rDLPFC, and hippocampus during suppression. We found a clear role of dACC in detecting the need for memory control and upregulating prefrontal inhibition. Importantly, we identified distinct early (300-450 ms) and late (500-700 ms) dACC contributions, suggesting both proactive control before recollection and reactive control in response to intrusions. Stronger early activity was associated with reduced hippocampal activity and diminished BOLD signal in dACC and rDLPFC, suggesting that preempting retrieval reduced overall control demands. In the later window, dACC activity was larger, and effective connectivity analyses revealed robust communication from dACC to rDLPFC and from rDLPFC to hippocampus, which are tied to successful forgetting. Together, our findings support a model in which dACC detects the emergence of unwanted content, triggering top-down inhibitory control, and in which rDLPFC countermands intruding thoughts that penetrate awareness.SIGNIFICANCE STATEMENT Preventing unwanted memories from coming to mind is an adaptive ability of humans. This ability relies on inhibitory control processes in the prefrontal cortex to modulate hippocampal retrieval processes. How and when reminders to unwelcome memories come to trigger prefrontal control mechanisms remains unknown. Here we acquired neuroimaging data with both high spatial and temporal resolution as participants suppressed specific memories. We found that the anterior cingulate cortex detects the need for memory control, responding both proactively to early warning signals about unwelcome content and reactively to intrusive thoughts themselves. When unwanted traces emerge in awareness, anterior cingulate communicates with prefrontal cortex and triggers top-down inhibitory control over the hippocampus through specific neural oscillatory networks.

Engaging People and Co-Producing Research with Persons and Communities to Foster Person-Centred Care: A Meta-Synthesis.

INTRODUCTION: Engagement and co-production in healthcare research and innovation are crucial for delivering person-centred interventions in underserved communities, but the knowledge of effective strategies to target this population is still vague, limiting the provision of person-centred care. Our research aimed to identify essential knowledge to foster engagement and co-production. MATERIALS AND METHODS: A meta-synthesis research design was used to compile existing qualitative research papers on health communication, engagement, and empowerment in vulnerable groups in high-income countries (HICs) from 2008 to 2018. A total of 23 papers were selected and analysed. RESULTS: 'Design and recruitment' and 'engagement and co-production' thematic areas are presented considering the factors related to researcher-communities attunement and the strategical plans for conducting research. The insights are discussed in light of the literature. Long-term alliances, sustainable structures, and strengthened bonds are critical factors for producing real long-term change, empowering persons and communities, and paving the way to person-centred care. CONCLUSIONS: The enhancement of the recruitment, involvement, and empowerment of traditionally disengaged communities and individuals depends on the awareness and analysis of social determinants, power differentials and specific tactics, and the capacity of researchers and individuals to apply all these principles in real-world practice.

Effectiveness and Safety of Acupuncture and Moxibustion in Pregnant Women with Noncephalic Presentation: An Overview of Systematic Reviews.

BACKGROUND: Breech presentation at the time of delivery is 3.8-4%. Fetuses that maintain a noncephalic presentation beyond 32 weeks will have a lower probability of spontaneous version before labor. Given the increasing interest in exploring the use of complementary medicine during pregnancy and childbirth, the moxibustion technique, a type of traditional Chinese medicine, could be another option to try turning a breech baby into a cephalic presentation. OBJECTIVES: To review the evidence from systematic reviews (SR) on the efficacy and safety of acupuncture and moxibustion in pregnant women with noncephalic presentation. MAIN RESULTS: Our SR synthesizes the results from five clinical trials on pregnant women with a singleton noncephalic presentation. There is evidence that moxibustion reduces the number of noncephalic presentations at the time of birth compared with no treatment. The adverse effects that acupuncture and moxibustion can cause seem to be irrelevant. Most SRs agree that there are no adverse effects directly related to acupuncture and moxibustion. CONCLUSIONS: Even though the results obtained are positive and the five reviews conclude that moxibustion reduces the number of noncephalic presentations at birth (alone or combined with postural techniques or acupuncture), there is considerable heterogeneity between them. Better methodologically designed studies are required in the future to reaffirm this conclusion.

Comparación de la producción vocal en niños con hipoacusia prelocutiva con adaptación audioprotésica e implante coclear con normooyentes / Vowel production in hearing impaired children: A comparison between normal-hearing, hearing-aided and cochlear-implanted children

Introducción y objetivos: La inadecuada retroalimentación auditiva en los niños con hipoacusia prelocutiva altera la articulación de consonantes y vocales. El propósito de esta investigación es comparar la producción de vocales en niños hipoacúsicos hispanohablantes con implante coclear o adaptación audioprotésica con niños normooyentes por medio del análisis acústico de las frecuencias formánticas y el espacio vocal. Método: Un total de 56 niños con hipoacusia prelocutiva (25 con implante coclear y 31 con audífonos) y 47 niños normooyentes participaron en el estudio. Los 2 primeros formantes (F1 y F2) de las 5 vocales del idioma español se midieron utilizando el programa Praat. Para analizar las diferencias entre los 3 grupos se aplicó el método ANOVA de análisis de la varianza y el test de Scheffé. También se calculó el área del espacio vocal. Resultados: El valor medio del F1 en todas las vocales no mostró diferencias significativas en los 3 grupos de niños. Para las vocales /i/, /o/ y /u/ el valor medio del F2 fue significativamente diferente entre los 2 grupos de niños hipoacúsicos y el grupo de niños normooyentes. Conclusión: Ambos grupos de niños con hipoacusia prelocutiva tienden a presentar sutiles desviaciones en la articulación de las vocales que pueden ser analizadas mediante un programa de análisis acústico

Introduction and objectives: Inadequate auditory feedback in prelingually deaf children alters the articulation of consonants and vowels. The purpose of this investigation was to compare vowel production in Spanish-speaking deaf children with cochlear implantation, and with hearing-aids with normal-hearing children by means of acoustic analysis of formant frequencies and vowel space. Methods: A total of 56 prelingually deaf children (25 with cochlear implants and 31 wearing hearing-aids) and 47 normal-hearing children participated. The first 2 formants (F1 and F2) of the five Spanish vowels were measured using Praat software. One-way analysis of variance (ANOVA) and post hoc Scheffé test were applied to analyze the differences between the 3 groups. The surface area of the vowel space was also calculated. Results: The mean value of F1 in all vowels was not significantly different between the 3 groups. For vowels /i/, /o/ and /u/, the mean value of F2 was significantly different between the 2 groups of deaf children and their normal-hearing peers. Conclusion: Both prelingually hearing-impaired groups tended toward subtle deviations in the articulation of vowels that could be analyzed using an objective acoustic analysis programme

Effectiveness and Estimation of Cost-Effectiveness of a Group-Based Multicomponent Physical Exercise Programme on Risk of Falling and Frailty in Community-Dwelling Older Adults.

This study analyses the effectiveness and cost-effectiveness of a group-based multicomponent physical exercise programme aimed at reducing the risk of falling and frailty in community-dwelling older adults. This is a pretest-posttest non-equivalent control group design, with an intervention group and a comparison group. Participants were evaluated at baseline and after 9 months. The effectiveness analyses showed significant reduction in the risk of falling (-45.5%; p = 0.000) and frailty (-31%; p = 0.000) after the intervention for the participants in the physical exercise programme. Moreover, these participants showed an improvement in limitations in activities of daily living, self-care ability and the use of health resources, physical performance, balance and body mass index. The cost-effectiveness analyses showed that the intervention was cost-saving and more effective than usual care scenario. A novel group-based multicomponent physical exercise programme showed to be more effective and cost-effective than usual care for older adults suffering from risk of falling and frailty.

Characterizing hippocampal dynamics with MEG: A systematic review and evidence-based guidelines.

The hippocampus, a hub of activity for a variety of important cognitive processes, is a target of increasing interest for researchers and clinicians. Magnetoencephalography (MEG) is an attractive technique for imaging spectro-temporal aspects of function, for example, neural oscillations and network timing, especially in shallow cortical structures. However, the decrease in MEG signal-to-noise ratio as a function of source depth implies that the utility of MEG for investigations of deeper brain structures, including the hippocampus, is less clear. To determine whether MEG can be used to detect and localize activity from the hippocampus, we executed a systematic review of the existing literature and found successful detection of oscillatory neural activity originating in the hippocampus with MEG. Prerequisites are the use of established experimental paradigms, adequate coregistration, forward modeling, analysis methods, optimization of signal-to-noise ratios, and protocol trial designs that maximize contrast for hippocampal activity while minimizing those from other brain regions. While localizing activity to specific sub-structures within the hippocampus has not been achieved, we provide recommendations for improving the reliability of such endeavors.

Objetivo: Realizar una evaluación de la evidencia científica publicada y explorar las estrategias e intervenciones más adecuadas en la presentación no cefálica con acupuntura o moxibustión. Método: Búsqueda bibliográfica realizada entre los años 2003 y 2018 con las palabras clave «acupuntura», «moxibustión», «presentación de nalgas» y «presentación no cefálica» en las bases de datos PubMed, Cinahl, WoS, Medline y CENTRAL. Resultados: Finalmente se seleccionaron 15 artículos que cumplían con los criterios de inclusión. La moxibustión es eficaz para conseguir la versión a cefálica en las embarazadas con feto en presentación no cefálica en el tercer trimestre de gestación. Los países asiáticos son los que obtienen resultados con mayor éxito (96,7%), respecto a los países occidentales (53,6-75,4%). Discusión: La revisión de la bibliografía nos ofrece una buena evidencia científica en relación con la efectividad de la moxibustión en el punto de acupuntura V67, en la versión del feto a una presentación cefálica. En la gran mayoría de los estudios se ha observado una mejora en la versión del feto en los grupos que aplicaron la técnica de moxibustión en V67 respecto al grupo control, en que no se había aplicado la técnica. Conclusión: En la actualidad, el uso de la moxibustión para la versión cefálica de una presentación no cefálica es un procedimiento de interés tanto para los profesionales sanitarios como para las gestantes, ya que es una técnica efectiva, segura y de fácil aplicación

Objective: To carry out an evaluation of the published scientific evidence and to explore the most appropriate strategies and interventions in the non-cephalic presentation with acupuncture or moxibustion. Method: Bibliographic search was carried out between 2003 and 2018 with the keywords «acupuncture», «moxibustion», «breech presentation», «non-cephalic presentation», in the databases PubMed, Cinahl, WoS, Medline and CENTRAL. Results: Finally, 15 articles were selected that met the inclusion criteria. Moxibustion is effective to achieve the cephalic version in pregnant women with a fetus in non-cephalic presentation in the third trimester of pregnancy. The Asian countries have the most successful results (96.7%) in relation to those in the West (between 53.6 and 75.4%). Discussion: The review of the literature offers us good scientific evidence regarding the effectiveness of moxibustion in V67, in the fetus version of a cephalic presentation. In the vast majority of studies, an improvement in the version of the fetus was observed in the groups that applied the moxibustion technique in V67 in relation to the control group, which had not applied the technique. Conclusion: At present, the use of moxibustion for the cephalic version of a non-cephalic presentation is a procedure of interest for health workers and pregnant women, since it is an effective, safe and easy to apply technique whenever it is indicated
