Improving quality of life in the elderly: hearing loss treatment with cochlear implants.

BACKGROUND: Hearing loss impacts health-related quality of life and general well-being and was identified in a Lancet report as one of the largest potentially modifiable factors for the prevention of age-related dementia. There is a lack of robust data on how cochlear implant treatment in the elderly impacts quality of life. The primary objective was to measure the change in health utility following cochlear implantation in individuals aged ≥ 60 years. METHODS: This study uniquely prospectively recruited a large multinational sample of 100 older adults (mean age 71.7 (SD7.6) range 60-91 years) with severe to profound hearing loss. In a repeated-measures design, pre and post implant outcome measures were analysed using mixed-effect models. Health utility was assessed with the Health Utilities Index Mark III (HUI3). Subjects were divided into groups of 60-64, 65-74 and 75 + years. RESULTS: At 18 months post implant, the mean HUI3 score improved by 0.13 (95%CI: 0.07-0.18 p < 0.001). There was no statistically significant difference in the HUI3 between age groups (F[2,9228] = 0.53, p = 0.59). The De Jong Loneliness scale reduced by an average of 0.61 (95%CI: 0.25-0.97 p < 0.014) and the Lawton Instrumental Activities of Daily Living Scale improved on average (1.25, 95%CI: 0.85-1.65 p < 0.001). Hearing Handicap Inventory for the Elderly Screening reduced by an average of 8.7 (95%CI: 6.7-10.8, p < 0.001) from a significant to mild-moderate hearing handicap. Age was not a statistically significant factor for any of the other measures (p > 0.20). At baseline 90% of participants had no or mild depression and there was no change in mean depression scores after implant. Categories of Auditory perception scale showed that all subjects achieved a level of speech sound discrimination without lip reading post implantation (level 4) and at least 50% could use the telephone with a known speaker. CONCLUSIONS: Better hearing improved individuals' quality of life, ability to communicate verbally and their ability to function independently. They felt less lonely and less handicapped by their hearing loss. Benefits were independent of age group. Cochlear implants should be considered as a routine treatment option for those over 60 years with bilateral severe to profound hearing loss. TRIAL REGISTRATION: ClinicalTrials.gov ( http://www.

Normocephalic sagittal craniosynostosis in young children is common and unrecognized.

OBJECTIVE: Sagittal craniosynostosis (SC) is usually diagnosed during early childhood by the presence of scaphocephaly. Recently, our group found 3.3% of children under 5 years of age with normocephalic sagittal craniosynostosis (NSC) using computed tomography (CT) scans. This paper aims to validate our preliminary findings using a larger cohort of patients, and analyze factors associated with incidental NSC. METHODS: A retrospective review of head CT scans in patients aged 0 to 71 months who presented to the emergency department of our tertiary care institution between 2008 and 2020 was completed. Patients with syndromes associated with craniosynostosis (CS), history of hydrocephalus, or other brain/cranial abnormalities were excluded. Two craniofacial surgeons reviewed the CT scans to evaluate the presence and extent of CS. Demographic information, gestational age, past medical and family history, medications, and chief complaint were recorded as covariates, and differences between patients with and without CS were analyzed. Furthermore, comparison of the prevalence of CS across age groups was studied. Additional analysis exploring association between independent covariates and the presence of CS was performed in two sub-cohorts: patients ≤ 24 months of age and patients > 24 months of age. RESULTS: A total of 870 scans were reviewed. SC was observed in 41 patients (4.71% - 25 complete, 16 incomplete), all with a normal cranial index (width/length > 0.7). The prevalence of SC increased up to 36 months of age, then plateaued through 72 months of age. Patients under 2 years of age with family history of neurodevelopmental disease had 49.32 (95% CI [4.28, 567.2]) times higher odds of developing CS. Sub-cohort of patients above 24 months of age showed no variable independently predicted developing CS. CONCLUSION: NSC in young children is common. While the impact of this condition is unknown, the correlation with family history of neurodevelopmental disease is concerning.

Eye oscilations with neurological implications in pediatric age.

INTRODUCTION: Eye oscillations, both nystagmic and non-nystagic, can occur from birth. Most correspond to infantile nystagmus that dubates in the first six months of life, which include idiopathic, sensory, latent, or overt latent motor nystagmus. Those associated with neurological diseases or syndromes correspond to approximately 33%, their identification and correct evaluation being important given the potential visual and vital complications. MATERIAL AND METHODS: We made a systematic review of the literature on supranuclear gaze control mechanisms and the main ocular oscillations with possible neurological implications, both in childhood. With this, we intend to assess if there are already established clinical-anatomical associations, and to propose a protocol on the complementary studies to be carried out in these cases. RESULTS: There are still anatomical pathways involved in supranuclear gaze control that are not fully clarified and understood. Besides, except in the case of nystagmus in seesaw and upbeat, we did not find anatomical explanations for their pathogenesis. The need for complete neuro-ophthalmological physical examinations and the request for additional tests in children who present ocular oscillations with neurological characteristics are clear. CONCLUSIONS: Supranuclear gaze control follows a complex neurological network that still needs to be studied better. With a better dissection of the same we could try to understand why the ocular oscillations that we studied have these specific forms of presentation. As for the complementary requests, the request for neuroimaging tests is practically constant, making the others according to the specific case before which we find ourselves.

Inner ear drug delivery through a cochlear implant: Pharmacokinetics in a Macaque experimental model.

OBJECTIVES: The method of drug delivery directly into the cochlea with an implantable pump connected to a CI electrode array ensures long-term delivery and effective dose control, and also provides the possibility to use different drugs. The objective is to develop a model of inner ear pharmacokinetics of an implanted cochlea, with the delivery of FITC-Dextran, in the non-human primate model. DESIGN: A preclinical cochlear electrode array (CI Electrode Array HL14DD, manufactured by Cochlear Ltd.) attached to an implantable peristaltic pump filled with FITC-Dextran was implanted unilaterally in a total of 15 Macaca fascicularis (Mf). Three groups were created (5 Mf in each group), according to three different drug delivery times: 2 hours, 24 hours and 7 days. Perilymph (10 samples, 1µL each) was sampled from the apex of the cochlea and measured immediately after extraction with a spectrofluorometer. After scarifying the specimens, x-Rays and histological analysis were performed. RESULTS: Surgery, sampling and histological analysis were performed successfully in all specimens. FITC-Dextran quantification showed different patterns, depending on the delivery group. In the 2 hours injection experiment, an increase in FITC-Dextran concentrations over the sample collection time was seen, reaching maximum concentration peaks (420-964µM) between samples 5 and 7, decreasing in successive samples, without returning to baseline. The 24-hours and 7-days injection experiments showed even behaviour throughout the 10 samples obtained, reaching a plateau with mean concentrations ranging from 2144 to 2564 µM and from 1409 to 2502µM, respectively. Statistically significant differences between the 2 hours and 24 hours groups (p = 0.001) and between the 2 hours and 7 days groups (p = 0.037) were observed, while between the 24 hours and 7 days groups no statistical differences were found. CONCLUSIONS: This experimental study shows that a model of drug delivery and pharmacokinetics using an active pump connected to an electrode array is feasible in Mf. An infusion time ranging from 2 to 24 hours is required to reach a maximum concentration peak at the apex. It establishes then an even concentration profile from base to apex that is maintained throughout the infusion time in Mf. Flow mechanisms during injection and during sampling that may explain such findings may involve cochlear aqueduct flow as well as the possible existence of substance exchange from scala tympani to extracellular spaces, such as the modiolar space or the endolymphatic sinus, acting as a substance reservoir to maintain a relatively flat concentration profile from base to apex during sampling. Leveraging the learnings achieved by experimentation in rodent models, we can move to experiment in non-human primate with the aim of achieving a useful model that provides transferrable data to human pharmacokinetics. Thus, it may broaden clinical and therapeutic approaches to inner ear diseases.

Maintenance treatment in metastatic colorectal cancer: in search of the best strategy.

Over the last 2 decades, the standard fluoropyrimidine-based chemotherapy backbone for metastatic colorectal cancer has been complemented by the addition of novel biological agents, achieving impressive increases in 5-year survival rates. Nonetheless, these new combinations have also entailed increases in toxicity, leading to evaluation of de-escalated chemotherapy regimens and "drug holiday" periods in attempts to reduce side effects and optimise quality of life without impairing efficacy. Here, we review the current and emerging evidence for maintenance schedules with chemotherapy and targeted agents, versus continuous treatment after induction treatment, in metastatic colorectal cancer patients.

[Psychiatric symptoms in a child with gluten sensitivity]. / Psychische klachten bij kind met glutensensitiviteit.

BACKGROUND: Non-celiac gluten sensitivity (NCGS) is a diagnosis that is increasingly being reported. Psychiatric symptoms can be a rare but serious manifestation of this new clinical entity. CASE REPORT: A 13-year-old girl consulted the paediatrician with abdominal pain, diarrhoea, bloating, and compulsive thoughts and fears; these disappeared on a gluten-free diet. Celiac disease and wheat allergy were excluded. Double-blind placebo-controlled gluten challenge confirmed the diagnosis NCGS. CONCLUSION: Consider a diagnosis of NCGS in patients with psychiatric symptoms in combination with abdominal symptoms.

Differential involvement of synovial adipokines in pain and physical function in female patients with knee osteoarthritis. A cross-sectional study.

OBJECTIVE: Adipokines have been reported to play a role in the development, progression and severity of knee osteoarthritis but the influence of the different adipokines are not well known. The aim of this study was to evaluate the association between different synovial fluid adipokines with pain and disability knee osteoarthritis patients. METHODS: Cross-sectional study with systematic inclusion of 115 symptomatic primary knee osteoarthritis female patients with ultrasound-confirmed joint effusion. Age, physical exercise, symptoms duration and different anthropometric measurements were collected. Radiographic severity was evaluated according to Kellgren-Lawrence scale. Pain and disability were assessed by WOMAC-total, -pain, -function subscales and Knee injury and Osteoarthritis Outcome Score (KOOS) pain and function scales. Seven adipokines and three inflammatory markers were measured by ELISA in synovial fluid. Partial Correlation Coefficient (PCC) and corresponding 95% confidence interval were used as a measure of association. RESULTS: Leptin, osteopontin and inflammatory factors, especially TNF-alpha, were associated to pain and function. After adjustment for potential confounders including inflammatory factors and all adipokines, an association was found for adiponectin with pain (PCC 0.240 [0.012, 0.444]) and for resistin and visfatin with function (PCC 0.336 [0.117, 0.524] and -0.262 [-0.463, -0.036]). No other adipokines or inflammatory markers were statistically and independently associated. An association between physical exercise and pain and disability remained after adjustment, whereas an attenuation of the influence of anthropometric measurements was observed. CONCLUSIONS: Different patterns of association between synovial fluid adipokines were observed regarding pain and disability in knee osteoarthritis patients. Specifically, adiponectin was associated to pain while resistin and visfatin were mainly related to function.

[Heart failure in primary care: Attitudes, knowledge and self-care]. / Insuficiencia cardiaca en atención primaria: actitudes, conocimientos y autocuidado.

OBJECTIVE: To determine the attitudes, knowledge, and self-care practices in patients with heart failure (HF) in Primary Care, as well as to identify factors associated with better self-care. DESIGN: Cross-sectional and multicentre study. SETTING: Primary Care. PARTICIPANTS: Subjects over 18 years old with HF diagnosis, attended in 10 Primary Health Care Centres in the Metropolitan Area of Barcelona. MAIN MEASUREMENTS: Self-care was measured using the European Heart Failure Self-Care Behaviour Scale. Sociodemographic and clinical characteristics, tests on attitudes (Self-efficacy Managing Chronic Disease Scale), knowledge (Patient Knowledge Questionnaire), level of autonomy (Barthel), and anxiety and depression screening (Goldberg Test), were also gathered in an interview. A multivariate mixed model stratified by centre was used to analyse the adjusted association of covariates with self-care. RESULTS: A total of 295 subjects (77.6%) agreed to participate, with a mean age of 75.6 years (SD: 11), 56.6% women, and 62% with no primary education. The mean self-care score was 28.65 (SD: 8.22), with 25% of patients scoring lower than 21 points. In the final stratified multivariate model (n=282; R2 conditional=0.3382), better self-care was associated with higher knowledge (coefficient, 95% confidence interval: -1.37; -1.85 to -0.90), and coronary heart disease diagnosis (-2.41; -4.36: -0.46). CONCLUSION: Self-care was moderate. The correlation of better self-care with higher knowledge highlights the opportunity to implement strategies to improve self-care, which should consider the characteristics of heart failure patients attended in Primary Care.

Surgical findings and auditory performance after cochlear implant revision surgery.

The objective of this study was to review cochlear reimplantation outcomes in the tertiary hospital and analyze whether facts such as type of failure, surgical findings, or etiology of deafness have an influence. A retrospective study including 38 patients who underwent cochlear implant revision surgery in a tertiary center is performed. Auditory outcomes (pure tone audiometry, % disyllabic words) along with etiology of deafness, type of complication, issues with insertion, and cochlear findings are included. Complication rate is 2.7 %. Technical failure rate is 57.9 % (50 % hard failure and 50 % soft failure), and medical failure (device infection or extrusion, migration, wound, or flap complication) is seen in 42.1 % of the cases. Management of cochlear implant complications and revision surgery is increasing due to a growing number of implantees. Cases that require explantation and reimplantation of the cochlear implant are safe procedures, where the depth of insertion and speech perception results are equal or higher in most cases. Nevertheless, there must be an increasing effort on using minimally traumatic electrode arrays and surgical techniques to improve currently obtained results.

High prevalence of cardiovascular co-morbidities in patients with symptomatic knee or hand osteoarthritis.

OBJECTIVES: To evaluate the frequency of cardiovascular events (CVEs) and metabolic syndrome (MetS) in patients with symptomatic knee or hand osteoarthritis (OA). METHOD: A cross-sectional study conducted by rheumatologists in a primary care setting. Consecutive symptomatic patients with primary knee or hand OA were included and patients with soft tissue conditions served as the control group. Hypertension, diabetes mellitus, obesity, dyslipidaemia, and CVEs consisting of myocardial infarction, angina, or cerebrovascular disease were recorded. RESULTS: A total of 254 OA patients (184 with knee OA and 70 with hand OA) and 254 control patients were included. The frequency of obesity was higher in all OA groups and hypertension was more frequent in knee OA. MetS was significantly more frequent in patients with OA as a whole group and in knee or hand OA groups separately (p < 0.001, p = 0.002, and p = 0.007, respectively, vs. control group), with odds ratio (OR) 2.4, 95% confidence interval (CI) 1.26-4.55 in the OA group, OR 2.29, 95% CI 1.15-4.54 in the knee OA group, and OR 2.67, 95% CI 1.15-6.19 in the hand OA group. A higher prevalence of CVEs in the three OA groups was observed compared with the control group. CONCLUSIONS: A high frequency of MetS and CVEs was observed in OA patients in a primary care setting.

[Guidelines for cochlear implant indication in Navarre]. / Guía clínica para la indicación de implantes cocleares en la Comunidad Foral de Navarra.

Cochlear implants are indicated in severe to profound hearing loss with no benefit with hearing aids. Since the beginning of cochlear implants 30 years ago, auditory outcomes have been improving due to changes introduced in differ-ent areas: electrode design, strategy, surgical technique... Given good results within this period of time, cochlear implant indication has varied too. The aim of this paper is to show an update on indication criteria for cochlear implantation in Navarre, for application in daily practice. The indications are established by consensus amongst the hospitals of the region.

In vivo attenuation and genetic evolution of a ST247-SCCmecI MRSA clone after 13 years of pathogenic bronchopulmonary colonization in a patient with cystic fibrosis: implications of the innate immune response.

Methicillin-resistant Staphylococcus aureus (MRSA) causes chronic pulmonary infections in patients with cystic fibrosis (CF). This study tracks the 13-year evolution (1996-2009) of a single MRSA clone in a male patient with CF, evaluating both the host immunogenic response and the microbial variations. Whole-genome sequencing was performed for the initial (CF-96) and evolved (CF-09) isolates. The immunogenicity of CF-96 and CF-09 was evaluated by incubation with innate immune cells from healthy volunteers. We also studied the patient's innate immune response profile, cytokine production, expression of triggering receptor expressed on myeloid cells-1 (TREM-1), and phagocytosis. A total of 30 MRSA ST247-SCCmecI-pvl(-) isolates were collected, which evidenced a genome size reduction from the CF-96 ancestor to the evolved CF-09 strain. Up to six changes in the spa-type were observed over the course of the 13-year evolution. Cytokine production, TREM-1 expression, and phagocytosis were significantly lower for the healthy volunteer monocytes exposed to CF-09, compared with those exposed to CF-96. Patient monocytes exhibited a reduced inflammatory response when challenged with CF-09. Genetic changes in MRSA, leading to reduced immunogenicity and entry into the refractory state, may contribute to the attenuation of virulence and efficient persistence of the bacteria in the CF lung.

Tuberculosis esofágica: informe de un caso / A Case Report of Esophageal Tuberculosis

Informamos el caso de un hombre inmunocompetente que consultó por cuadro de sangrado digestivo alto secundario a una úlcera esofágica de origen tuberculoso. El compromiso gastrointestinal por el Mycobacterium tuberculosis es raro aun en pacientes con altas prevalencias de enfermedad pulmonar y extrapulmonar; los sitios de mayor afectación son íleon terminal y el peritoneo, la enfermedad esofágica es exótica y generalmente es secundaria a la extensión proveniente de órganos vecinos infectados, como ganglios mediastinales y/o bronquios. La clínica, las imágenes endoscópicas y radiológicas de la enfermedad esofágica suele simular una neoplasia maligna. La quimioterapia antituberculosa es la base del tratamiento, rara vez se requiere manejo quirúrgico.

We report the case of an immune-competent man with symptoms of upper gastrointestinal bleeding secondary to esophageal ulcers of tubercular origin. Gastrointestinal involvement from Mycobacterium tuberculosis is rare even in patients with numerous occurrences of pulmonary and extrapulmonary diseases. The most frequently affected sites are the terminal ileum and the peritoneum. Esophageal tuberculosis is exotic and is usually secondary to extension from neighboring infected organs such as the mediastinal nodes and/or the bronchi. Clinical, endoscopic and radiological pictures of the esophageal disease often mimic malignancy. Tuberculosis treatment is the mainstay of treatment, and surgery is rarely required.

Enfermedad de Alzheimer y disfagia. Desarrollo del compromiso deglutorio / The development of compromised Swallowing in patients with Alzheimer’s Disease and dysphagia

La disfagia es síntoma común en varias enfermedades neurológicas, en afectados por eventos cerebrovasculares o como consecuencia de traumas craneoencefálicos. Otro grupo importante que desarrolla trastornos de la deglución son aquellos adultos mayores con pérdida progresiva de las funciones cognitivas como es el caso de pacientes con demencia tipo Alzheimer, en donde la enfermedad se acompaña de complicaciones respiratorias que son potencialmente evitables, si la disfagia es reconocida precozmente y se trata adecuadamente

Dysphagia is a common symptom in many neurological diseases, particularly occurring after a stroke or head trauma. Another important group of patients who develop swallowing dysfunctions are older adults with progressive loss of cognitive functions such as patients with Alzheimer’s disease. This type of disease is accompanied by diffi culty swallowing that has been associated with increased mortality due to respiratorycomplications that are potentially preventable if dysphagia is recognized early so that appropriate strategiesfor treatment can be used

[Mexican consensus on portal hypertension]. / Consenso Mexicano de Hipertensión Portal.

The aim of the Mexican Consensus on Portal Hypertension was to develop documented guidelines to facilitate clinical practice when dealing with key events of the patient presenting with portal hypertension and variceal bleeding. The panel of experts was made up of Mexican gastroenterologists, hepatologists, and endoscopists, all distinguished professionals. The document analyzes themes of interest in the following modules: preprimary and primary prophylaxis, acute variceal hemorrhage, and secondary prophylaxis. The management of variceal bleeding has improved considerably in recent years. Current information indicates that the general management of the cirrhotic patient presenting with variceal bleeding should be carried out by a multidisciplinary team, with such an approach playing a major role in the final outcome. The combination of drug and endoscopic therapies is recommended for initial management; vasoactive drugs should be started as soon as variceal bleeding is suspected and maintained for 5 days. After the patient is stabilized, urgent diagnostic endoscopy should be carried out by a qualified endoscopist, who then performs the corresponding endoscopic variceal treatment. Antibiotic prophylaxis should be regarded as an integral part of treatment, started upon hospital admittance and continued for 5 days. If there is treatment failure, rescue therapies should be carried out immediately, taking into account that interventional radiology therapies are very effective in controlling refractory variceal bleeding. These guidelines have been developed for the purpose of achieving greater clinical efficacy and are based on the best evidence of portal hypertension that is presently available.

Várices gástricas: un reto para el manejo endoscópico / Gastric varices: a challenge for endoscopic management

La hemorragia de vías digestivas altas por várices gástricas, aunque menos frecuente que la secundaria a lasesofágicas, es una causa de alta mortalidad en los pacientes cirróticos. La ligadura es el tratamiento óptimoen las várices esofágicas, pero este tratamiento para las gástricas es todavía muy discutido.Presentamos el caso de una anciana, con antecedente de cirrosis hepática secundaria a esteatosis hepáticano alcohólica (NASH), que ingresa, con hemorragia de vías digestivas altas, evidenciándose en laesofagogastroduodenoscopia una várice fúndica subcardial con sangrado activo, para la cual se decide manejocon ligadura con banda de caucho con resultado exitoso y desaparición de la várice en control posterior

Upper digestive tract bleeding due to gastric varices, although less common than bleeding secondary toesophageal varices, is one of the causes of high mortality in cirrhotic patients. Although band ligation is theoptimal treatment for esophageal varices, its use for gastric varices is still hotly debated.We report the case of an elderly woman with a history of hepatic cirrhosis secondary to nonalcoholicsteatohepatitis (NASH) and obesity who was admitted to the hospital with upper digestive tract bleeding.An esophagogastroduodenoscopy showed an actively bleeding subcardial varice in the gastric fundus. Thedecision was made to manage the bleeding with rubber band ligation. The outcome was successful outcome,and the varice had disappeared in subsequent check-ups

[p53 expression in the gastric mucosa of patients infected with Helicobacter pylori]. / p53 expresado en la mucosa gástrica de pacientes infectados por Helicobacter pylori.

BACKGROUND: Helicobacter pylori (Hp) is recognized as a type 1 carcinogen for gastric cancer associated with pre-neoplastic lesions (atrophy and intestinal metaplasia [IM]). Its relation with p53, which intervenes in the cell cycle, has had contradictory results. AIMS: To analyze p53 expression in gastric mucosa and its relation with Hp infection. METHODS: A 3-month prospective, observational, cross-sectional study was conducted. Patients that had no evidence of acute or clinically significant gastric pathology had biopsies taken according to the Sydney system at the Hospital Juárez de México and the histopathologic studies were done at the Hospital Español de México. RESULTS: Hp prevalence was 32.7% in 104 patients. There were no cases of atrophy or dysplasia. A total of 91% of the infected patients were positive for p53. Of the non-infected patients, 14% were positive for p53 and 60% of them had IM. Of the IM patients, 75% presented with positive p53. Of the patients without IM, 31 presented with positive p53, and Hp was positive in 85% of them. There was association between Hp and p53 and between p53 and IM (P<.0001 and P<.0006, respectively). CONCLUSIONS: Significant association was shown between Hp and p53 expression, even in patients with pre-neoplastic lesions that no longer presented with Hp. Given that the identification of pre-neoplastic lesions is important for the prevention of cancer, immunohistochemistry could benefit routine biopsy carried out during endoscopy for the detection of Hp, by identifying patients with expression of the important oncogene regulator, p53.
