[Retinal alterations detected by non-mydriatic retinal camera screening and referral to ophthalmology in a population with high cardiovascular risk]. / Alteraciones retinianas detectadas por screening con cámara retinal no midriática y derivación a oftalmología en una población de alto riesgo cardiovascular.

OBJECTIVE: To describe the main retinal alterations detected by non-mydriatic retinal camera screening and to evaluate factors related to referral to ophthalmology in a population at high cardiovascular risk in Palmira, Colombia. MATERIALS AND METHODS: Cross-sectional observational study, which included 11,983 photographic imaging records of patients with hypertension and diabetes mellitus from Gesencro's S.A.S. comprehensive chronic disease care program between 2018 and 2020. Risk factors associated to referral to ophthalmology were evaluated with logistic regression, and crude and adjusted ORs (odds ratios) were obtained. RESULTS: A total of 11,880 records were analyzed; 67.7±12years old, and 69.5% were women. Among the retinal alterations were patients with diabetic retinopathy classified as more than mild in 10% and gradeI hypertensive retinopathy in 54.9% right eye, 51.9% left eye. Macular edema was also identified. Only 2069 patients (17.4%) required referral to ophthalmology, and for imaging control 82.6%. In the multivariate analysis, the risk factors associated with the probability of being referred were male gender, age 60years and older, glycosylated hemoglobin out-of-target, advanced chronic kidney disease and the microalbumin-to-creatinine ratio moderate to severely elevated. CONCLUSION: This study makes it possible to determine the importance of screening with a non-mydriatic retinal camera in patients at high cardiovascular risk to detect retinal abnormalities and assess risk factors associated with referral to ophthalmology. Early documentation of ocular compromise in these patients could prevent and avoid visual impairment and blindness.

[Asthma as a Protective Factor Against Mortality in Mexican Population with COVID-19]. / Asma como factor asociado a disminución de la mortalidad en población mexicana con COVID-19.

BACKGROUND: SARS-CoV-2 infection associated with the presence of comorbidities increased the risk of mortality. However, the role of asthma as a predictor of mortality and severity has not been defined. AIM: To assess the impact of asthma as a factor associated with the decrease in mortality in the Mexican population with COVID-19. METHODOLOGY: We performed a cross-sectional and secondary analysis of the database of the General Directorate of Epidemiology of the Mexican Government, updated to May 2023. The analysis included the Mexican population with a confirmed diagnosis of SARS-CoV-2 by RT-PCR. RESULTS: A total of 617,367 participants were included, with a mean age of 36. Mortality was 0.9%, 0.2% required admission to the intensive care unit (ICU). The prevalence of asthma in this population was 1.9%. When performing the multivariate logistic regression analysis, we found that the presence of asthma decreased the risk of mortality, with an OR of 0.57 (95% CI 0.45, 0.72; p = < 0.001). The variables of age > 60 years, smoking, arterial hypertension, Diabetes, Chronic Obstructive Pulmonary Disease (COPD), cardiovascular disease, and chronic kidney disease (CKD) were factors associated with an increase in mortality. The diagnosis of asthma was not associated with mechanical ventilation or ICU admission. CONCLUSION: The presence of asthma in patients with COVID-19 decreased the risk of mortality by 43%. The immunological context could explain the decreased risk of mortality in asthmatic patients infected with SARS-CoV-2.

Factores asociados al control de síntomas nucleares en pacientes pediátricos con trastorno de déficit de atención e hiperactividad, en un centro especializado de Medellín entre 2018 y 2019 / Factors associated with the control of nuclear symptoms in pediatric patients with Attention Deficit Hyperactivity Disorder in a specialized center in Medellín between 2018 and 2019 / Fatores associados ao controle de sintomas nucleares em pacientes pediátricos com transtorno de déficit de atenção e hiperatividade, em um centro especializado em Medellín entre 2018 e 2019

Objetivo: el trastorno de déficit de atención e hiperactividad (TDAH) ha sido descrito como el trastorno del neurodesarrollo más común en la infancia. Esta condición se asocia a un significativo deterioro en calidad de vida, múltiples comorbilidades y, a largo plazo, a menores logros académicos y laborales. A pesar de que se ha evidenciado que en los pacientes de ascendencia latina se presenta un posible subdiagnóstico, que en Colombia se han estimado prevalencias mayores a las descritas en el planeta, y que los efectos de la pandemia por Covid-19 han podido exacerbar esta problemática, el volumen de estudios con estimaciones reproducibles sobre las características, tratamientos recibidos y control de síntomas de estos pacientes aún requiere ampliarse. Este estudio busca establecer los factores sociodemográficos, clínicos y del tratamiento asociados al control de los síntomas nucleares de este trastorno, que consisten en patrones persistentes y generalizados de inatención, impulsividad e hiperactividad. Metodología: estudio descriptivo con intención analítica en una cohorte retrospectiva de pacientes pediátricos con trastorno de déficit de atención e hiperactividad seguidos durante seis meses en un centro especializado de Medellín, Colombia, entre 2018 y 2019. Resultados: se identificó una incidencia de control de síntomas de 46,7% que se asoció de manera significativa con la adherencia al tratamiento y con historia familiar de TDAH. Conclusiones: puede afirmarse que, en pacientes pediátricos con TDAH, estos factores podrían aumentar la probabilidad de lograr el control de los síntomas nucleares.

Objective: Attention Deficit Hyperactivity Disorder (ADHD) has been described as the most common neurodevelopmental disorder in childhood. This condition is associated with significant deterioration in the quality of life, multiple comorbidities and, in the long term, lower academic and work achievements. Despite the fact that it has been shown that patients of Latin descent present a possible underdiagnosis, that in Colombia higher prevalence has been estimated than those described worldwide, and that the effects of the Covid-19 pandemic have been able to exacerbate this problem, the volume of studies with reproducible estimates on the characteristics, treatments received, and symptom control of these patients still needs to be expanded. This study seeks to establish the sociodemographic, clinical and treatment factors associated with the control of the core symptoms of this disorder, which consist of persistent and generalized patterns of inattention, impulsivity and hyperactivity. Methodology: Descriptive study with analytical intent in a retrospective cohort of pediatric patients with attention deficit hyperactivity disorder followed up for 6 months in a specialized center in Medellín, Colombia, between 2018 and 2019. Results: An incidence of symptom control of 46.7% was identified, which was significantly associated with adherence to treatment and with a family history of ADHD. Conclusions: It can be affirmed that, in pediatric patients with ADHD, these factors could increase the probability of achieving control of nuclear symptoms.

Objetivo: o transtorno dedéficit de atenção e hiperatividade (TDAH) tem sido descrito como o transtorno do neurodesenvolvimento mais comum na infância. Esta condição está associada a uma deterioração significativa na qualidade de vida, múltiplas comorbidades e, a longo prazo, menores rendimentos acadêmicos e profissionais. Apesar de ter sido demonstrado que os pacientes de ascendência latina apresentam um possível subdiagnóstico, e que na Colômbia foram estimadas prevalências mais altas do que as descritas no planeta e que os efeitos da pandemia de Covid-19 foram capazes de exacerbar esse problema, o volume de estudos com estimativas reprodutíveis sobre as características, tratamentos recebidos e controle de sintomas desses pacientes ainda precisam ser ampliados. Este estudo busca estabelecer os fatores sociodemográficos, clínicos e de tratamento associados ao controle dos sintomas centrais desse transtorno, que consistem em padrões persistentes e generalizados de desatenção, impulsividade e hiperatividade. Metodologia: estudo descritivo com intenção analítica em uma coorte retrospectiva de pacientes pediátricos com transtorno de déficit de atenção e hiperatividade acompanhados por seis meses em um centro especializado em Medellín, Colômbia, entre 2018 e 2019.Resultados: identificou-se uma incidência de controle dos sintomas de 46,7%, signifi-cativamente associada à adesão ao tratamento e ao histórico familiar de TDAH.Conclusões: Pode-se afirmar que, em pacientes pediátricos com TDAH , esses fatores podem aumentar a probabilidade de controle dos sintomas nucleares.

Evaluation of the Feasibility, Safety and Efficacy of the Use of Intravenous Infusions of Adenosine Triphosphate (ATP) in People Affected by Moderate to Severe Alzheimer's Disease: A Double-Blind Masked Clinical Trial for Dose Finding.

BACKGROUND: There are currently no drug therapies modifying the natural history of patients suffering Alzheimer's disease (AD). Most recent clinical trials in the field include only subjects in early stage of the disease, while patients with advanced AD are usually not represented. OBJECTIVES: To evaluate the feasibility, safety and efficacy of systemic infusions of adenosine triphosphate (ATP) in patients with moderate to severe AD, and to select the minimum effective dose of infusion. DESIGN: A phase IIb, randomized, double-blind, placebo-controlled clinical trial investigates. PARTICIPANTS: A total of 20 subjects with moderate or severe AD were included, 16 in the treatment group and 4 in the placebo group (4:1 randomization) at two dosage regimens, 6-hour or 24-hour infusions. RESULTS: The proof-of-concept study was successfully conducted, with no significant deviations from the study protocol and no serious adverse events reported. Regarding efficacy, only marginal differences were observed between ATP and placebo arms for H-MRS and MMSE variables. CONCLUSIONS: Our study demonstrates that the use of ATP infusion as therapy is feasible and safe. Larger studies are however needed to assess the efficacy of ATP in moderate to severe AD.

Recommendations of the Society of Thoracic Surgery and the Section of Cardiothoracic and Vascular Surgery of the Spanish Society of Anesthesia, Resuscitation and Pain Therapy, for patients undergoing lung surgery included in an intensified recovery program.

In recent years, multidisciplinary programs have been implemented that include different actions during the pre, intra and postoperative period, aimed at reducing perioperative stress and therefore improving the results of patients undergoing surgical interventions. Initially, these programs were developed for colorectal surgery and from there they have been extended to other surgeries. Thoracic surgery, considered highly complex, like other surgeries with a high postoperative morbidity and mortality rate, may be one of the specialties that most benefit from the implementation of these programs. This review presents the recommendations made by different specialties involved in the perioperative care of patients who require resection of a lung tumor. Meta-analyzes, systematic reviews, randomized and non-randomized controlled studies, and retrospective studies conducted in patients undergoing this type of intervention have been taken into account in preparing the recommendations presented in this guide. The GRADE scale has been used to classify the recommendations, assessing on the one hand the level of evidence published on each specific aspect and, on the other hand, the strength of the recommendation with which the authors propose its application. The recommendations considered most important for this type of surgery are those that refer to pre-habilitation, minimization of surgical aggression, excellence in the management of perioperative pain and postoperative care aimed at providing rapid postoperative rehabilitation.

Subretinal abscess due to Candida tropicalis in a patient with acute myeloid leukaemia: Case report.

A 54-year-old female patient with a history of acute myeloid leukaemia and receiving maintenance chemotherapy had a systemic relapse. She also had candidaemia caused by Candida tropicalis. Her blood cultures were negative after receiving antifungal treatment. Later, she had an ophthalmological assessment as part of the protocol, without ocular discomfort. In the fundoscopic examination, a whitish chorioretinal lesion was found in the left eye in relation to subretinal abscess, which correlated with retinal angiography and optical coherence tomography. The patient was treated with systemic antifungals with a favourable resolution of the lesion.

Improving medication adherence and effective prescribing through a patient-centered prescription model in patients with multimorbidity.

PURPOSE: This study aimed to assess the impact of the patient-centered prescription (PCP) model in medication adherence and effective prescribing in patients with multimorbidity. METHODS: Uncontrolled before-after study in an intermediate care facility in a mixed urban-rural district. Inpatients aged ≥ 65 years with multimorbidity exposed to polypharmacy before hospital admission were consecutively enrolled. Every patient's treatment plan was analyzed through the PCP model, which includes interventions aimed at improving medication adherence. The primary endpoint was the change in the proportion of adherent patients between pre-admission and after discharge for all regularly scheduled long-term medications, using the proportion of days covered (PDC). Secondary endpoints included the change on mean PDC for all long-term medications, number of long-term medications, proportion of patients with hyperpolypharmacy, medication regimen complexity index (MRCI) score, drug burden index (DBI) score, number of potential inappropriate prescribing (PIP), and proportion of patients with ≥ 2 PIPs. RESULTS: Ninety-three non-institutionalized patients were included (mean age 83.0 ± SD 6.1 years). The proportion of adherent patients increased from 22.1 to 51.9% (P < 0.001). Intervention also improved mean PDC [mean difference (95% CI) 10.6 (7.7, 13.5)] and effective prescribing through a reduction on the number of long-term medications [- 1.3 (- 1.7, - 0.9)], proportion of patients exposed to hyperpolypharmacy (- 16.1%, P < 0.001), MRCI score [- 2.2 (- 3.4, - 1.0)], DBI score [- 0.16 (- 1.8, - 1.3)], number of PIPs [- 1.6 (- 1.8, - 1.3)], and proportion of patients with ≥ 2 PIPs (- 53.7%, P < 0.001). CONCLUSION: Studied intervention provides significant effective prescribing and medication adherence enhancements in non-institutionalized older patients with multimorbidity and polypharmacy.

Second victim phenomenon in a surgical area: Online survey.

BACKGROUND AND AIM OF STUDY: An effective and accessible first source of support for second victims (SV) is usually the colleagues themselves, who should have tools to help emotionally and detect the unusual course of a SV. The aim of this work is to assess health professionals' perception of the phenomenon, as well as their capability to apply psychological first aid. MATERIAL AND METHODS: Observational descriptive study through online surveys answered anonymously. Participants were different health professionals from surgical area, mainly from a third-level hospital. RESULTS: 329 responses, 67 anaesthesiologists, 110 anaesthesiologists in training, 152 nurses. 78.4% had felt SV, more frequent among anaesthesiologists; however, 58% had never heard of the term. Guilt was the most frequent emotion. Residents were more afraid of judgmental colleagues and thought more about drop out their training. From those who sought help, most did it through a colleague, but most did not feel useful in helping a SV. 66% affirmed there is a still punitive, evasive or silent culture about medical incidents. CONCLUSIONS: Despite the frequency of the phenomenon there is still lack of knowledge of the term SV. Impact of the phenomenon is heterogenous and changes based on experience and responsibility. Colleagues are the first source of emotional help but there is a lack of tools to be able to provide it. Institutions are urged to create training programs so that professionals can guarantee «psychological first aid¼.

[Survey about the impact of COVID-19 on the traumatology and orthopedic surgery departments in Spain]. / Encuesta acerca del impacto de la COVID-19 en los servicios de Cirugía Ortopédica y Traumatología de España.

INTRODUCTION: We designed and conducted a survey to analyze the impact of the COVID-19 pandemic on the operation and performance of the orthopedic departments of the National Health System and private entities. MATERIAL AND METHODS: Descriptive study of a survey is distributed to Spanish Ortohopedic surgeons via Internet. RESULTS: 401 valid responses were obtained, out of these 85.7% had to reduce their surgical activity between 50% and 100%. 46% of the sample were asked to collaborate in other units or services and another 43% felt that their work had been underused. 52% modified the treatment indications in various bone fractures, with variability between centers and communities. 30% reported being satisfied with the management from the state and 60% with that of their province and center. 70% showed little to no satisfaction with the training received on the use of masks and personal protective equipment. An additional of 80% were also unsatisfied with the training received with regard to sample-taking. 65% did not have protective equipment to carry out their work. 46% have been denied protective measures to treat patients with suspected or confirmed infection. CONCLUSION: The COVID-19 pandemic has placed the National Health System in an extremely serious situation. Through the analysis of the results, we can observe an inefficient use of available human resources, a widespread discontent, as well as an absence of means and measures, which has had a direct impact on the number of infected professionals.

Identifying and preventing burnout in young oncologists, an overwhelming challenge in the COVID-19 era: a study of the Spanish Society of Medical Oncology (SEOM).

BACKGROUND: Young oncologists are at particular risk of professional burnout, and this could have a significant impact on their health and care of their patients. The coronavirus disease 2019 (COVID-19) pandemic has forced rapid changes in professionals' jobs and training, with the consequent physical and psychological effects. We aimed to characterize burnout levels and determinants in young oncologists, and the effects of the pandemic on their training and health. METHODS: Two online surveys were conducted among oncology residents and young oncology specialists in Spain. The first addressed professional burnout and its determinants before the COVID-19 pandemic, while the second analyzed the impact of the pandemic on health care organization, training, and physical and psychological health in the same population. RESULTS: In total, 243 respondents completed the first survey, and 263 the second; 25.1% reported significant levels of professional burnout. Burnout was more common among medical oncology residents (28.2%), mainly in their second year of training. It was significantly associated with a poor work-life balance, inadequate vacation time, and the burnout score. Nearly three-quarters of respondents (72%) were reassigned to COVID-19 care and 84.3% of residents missed part of their training rotations. Overall, 17.2% of this population reported that they had contracted COVID-19, 37.3% had scores indicating anxiety, and 30.4% moderate to severe depression. Almost a quarter of young oncologists (23.3%) had doubts about their medical vocation. CONCLUSIONS: Burnout affects a considerable number of young oncologists. The COVID-19 pandemic has had a profound impact on causes of burnout, making it even more necessary to periodically monitor it to define appropriate detection and prevention strategies.

Green Synthesis of Iron Oxides and Phosphates via Thermal Treatment of Iron Polyphenols Synthesized by a Camellia sinensis Extract.

Iron oxide nanoparticles (FeONPs) prepared with plant extracts have been emerging as green and sustainable materials. FeONPs are usually amorphous due to the chelation of the tea polyphenols (TPs) to the iron, and the real nature of the iron compounds is not completely understood. The main goal of this study was to investigate the behavior of the green FeONPs synthesized from an Fe3+ salt and Cammelia sinensis (black tea) extract upon thermal treatment, in order to remove TPs and enable the formation of crystalline materials suitable for a thorough characterization and with the potential for diverse applications. The as-prepared FeONPs were assigned as mixed-valence Fe(III) oxyhydroxides and Fe(II)/Fe(III) ions bound to TPs. A detailed description of the phase transformation upon heating revealed the formation of the rare nano ß-Fe2O3 phase at 400 °C, followed by a transformation to α-Fe2O3 as the temperature increased. Above 600 °C, the unprecedented formation of FePO4 and Fe3PO7 was observed, produced from the reaction of Fe2O3 and free phosphate ions present in the black tea leaves, Fe3PO7 being the major phase obtained at 900 °C. Finally, the catalytic potential of the FeONPs to treat the azo dye methyl orange through a heterogeneous Fenton-like system was investigated.

Estimación de riesgo cardiovascular ateroesclerótico en pacientes adultos sin sospecha de cifras tensionales elevadas / Estimation of aterosclerotic cardiovascular risk in adult patients without a suspicion of having high pressure readings / Estimativa do risco cardiovascular aterosclerótico em pacientes adultos sem suspeita de níveis elevados de tensão arterial

RESUMEN Introducción: Las enfermedades cardiovasculares representan la primera causa de muerte en el mundo. La estimación del Riesgo Cardiovascular (RCV) podría disminuir la carga de la enfermedad y mejorar la calidad de vida de los pacientes. Objetivo: Estimar el RCV en pacientes sin sospecha de cifras tensionales elevadas en una Clínica de Medicina Familiar en la Ciudad de México. Métodos: Estudio transversal descriptivo, participaron 101 pacientes de sexo masculino y femenino, de 40 a 69 años, sin diagnóstico previo de Hipertensión Arterial (HTA), pero que presentaron cifras tensionales altas al momento del estudio. Para diagnosticar HTA se utilizaron los criterios de la Asociación Americana del Corazón-2017. El RCV se evaluó con el ASCVD-Risk Estimator Plus. Resultados: En la muestra la HTA estuvo presente en el 55.4 %, 44.6 % manifestaron presión arterial elevada. Respecto al RCV, 54.4 % presentaron bajo riesgo, 11.8 % riesgo límite, 25.7 % intermedio y 7.9 % alto. Los factores de RCV con mayor prevalencia fueron diabetes mellitus tipo 2 (DM2), sobrepeso, obesidad y elevación de cifras tensionales. Discusión: Un porcentaje importante de participantes presentó RCV en sus diferentes categorías. Se requiere ser más estrictos en los parámetros utilizados para definir la HTA; pues sin intervenciones oportunas las enfermedades cardiovasculares continuarán incrementándose. Conclusión: Cerca de la mitad de los casos presentaron un RCV de límite a alto. Existió alta prevalencia de factores de riesgo individuales como DM2, HTA y dislipidemia. Se deben fortalecer búsquedas intencionadas de pacientes con características similares a las de este estudio para prevenir el desarrollo de enfermedades cardiovasculares.

ABSTRACT Introduction: Cardiovascular diseases are the main cause of death in the world. The estimation of the Cardiovascular Risk (CVR) could both reduce the burden of the illness and improve the quality of life of the patients. Objective: To estimate the CVR in adult patients without a suspicion of having high pressure readings in a Clinic of Family Medicine in Mexico City. Methods: This is a descriptive and transversal study with a sample of 101 male and female patients in the range of 40 to 69 years old, who did not have a previous hypertension diagnosis but who, at the moment of this study, showed high tension readings. The American Heart Association 2017 criteria were used. The cardiovascular risk was assessed using the ASCVD-Risk Estimator Plus. Results: Arterial hypertension readings were found in 55.4 % of the sample. 54.4 % of the sample met the criteria for low risk, 11.8 % for limit risk, 25.7 % for medium risk, and 7.9 % for high risk. The most prevalent factors associated with cardiovascular risk were type 2 diabetes mellitus, overweight, obesity, and hypertension. Discussion: An important percentage of the sample showed cardiovascular risk to some degree, suggesting that perhaps using stricter parameters to define hypertension could prompt more timely interventions. Conclusion: Considering both the high percentage of participants who demonstrated having a cardiovascular risk of concern and the high prevalence of risk factors such as Type 2 Diabetes Mellitus, hypertension, and overweight, timely monitoring interventions should be promoted in order to prevent the development of cardiovascular diseases.

RESUMO Introdução: As doenças cardiovasculares representam a principal causa de morte a nível mundial. A estimativa do risco cardiovascular (RCV) poderia diminuir o peso da doença e melhorar a qualidade de vida dos pacientes. Objetivo: Estimar o RCV em pacientes sem suspeita de tensão arterial elevada em uma Clínica de Medicina Familiar na Cidade do México. Métodos: Um estudo descritivo transversal envolvendo 101 pacientes do sexo masculino e feminino com idades entre os 40 - 69 anos, sem diagnóstico prévio de hipertensão (HTA), mas com tensão arterial elevada no momento do estudo. Os critérios da American Heart Association-2017 foram utilizados para diagnosticar o HTA. O RCV foi avaliado utilizando o ASCVD-Risk Estimator Plus. Resultados: Na amostra, a HTA esteve presente em 55,4 %, 44,6 % reportou tensão arterial elevada. Em relação à RCV, 54,4 % apresentavam baixo risco, 11,8 % risco limite, 25,7 % risco intermédio e 7,9 % alto risco. Os fatores de RCV mais prevalentes foram a diabetes melito tipo 2 (DM2), excesso de peso, obesidade e tensão arterial elevada. Discussão: Uma percentagem significativa de participantes tinha RCV em diferentes categorias. Há necessidade de ser mais rigoroso nos parâmetros utilizados para definir a HTA; sem intervenções atempadas, as doenças cardiovasculares continuarão aumentando. Conclusão: Quase metade dos casos tinham um limite de RCV elevado. Havia uma elevada prevalência de fatores de risco individuais tais como DM2, hipertensão e dislipidemia. A procura intencional de pacientes com características semelhantes às deste estudo deve ser reforçada para prevenir o desenvolvimento de doenças cardiovasculares.

Trends of incidence, mortality and survival of multiple myeloma in Spain. A twenty-three-year population-based study.

BACKGROUND: Despite major advances, multiple myeloma remains an incurable disease. Epidemiological data from high-quality population-based registries are needed to understand the heterogeneous landscape of the disease. METHODS: Incidence, mortality and survival in multiple myeloma were comprehensively analyzed in the Girona and Granada population-based cancer registries, over a 23-year study (1994-2016), divided into three periods (1994-2001, 2002-2009 and 2010-2016). Joinpoint regression analysis was used to estimate the annual percentage change in incidence and mortality. Age-standardized net survival was calculated with the Pohar-Perme method. RESULTS: 1957 myeloma patients were included in the study, with a median age of 72 years. Age-standardized incidence and mortality rates decreased over time in both sexes and both rates were higher in males. Five-year age-standardized net survival by period was 27.4% (1994-2001), 38.8% (2002-2009), and 47.4% (2010-2016). Survival improved for all age groups: 32.4%, 74.1% and 78.5% for patients aged 15-49; 27.5%, 44.6%, and 58.5% for those aged 50-69; finally, 24.8%, 25.5%, and 26.3% for the older group. CONCLUSION: Incidence remained overall stable throughout the study, with only a small increase for men. Mortality was progressively decreasing in both sexes. Both incidence and mortality were higher in men. Age plays a critical role in survival, with impressive improvement in patients younger than 70 years, but only a minor benefit in those older than 70.

Therapeutic optimization through goal-oriented prescription in nursing homes.

Background People living in nursing homes are highly vulnerable and frail. Polypharmacy and inappropriate prescription (IP) are also common problems. Objectives The objectives of the study are (i) to study the baseline situation and calculate the frailty index (FI) of the residents, (ii) to assess the results of routine clinical practice to do a pharmacotherapy review (patient-centred prescription (PCP) model) (Molist Brunet et al., Eur Geriatr Med. 2015;6:565-9) and (iii) to study the relationship between IP and frailty, functional dependence, advanced dementia and end-of-life situation. Setting Two nursing homes in the same geographical area in Catalonia (Spain). Method This was a prospective, descriptive and observational study of elderly nursing home residents. Each patient's treatment was analysed by applying the PCP model, which centres therapeutic decisions on the patient's global assessment and individual therapeutic goal. Main outcome measure Prevalence of polypharmacy and IP. Results 103 patients were included. They were characterized by high multimorbidity and frailty. Up to 59.2% were totally dependent. At least one IP was identified in 92.2% of residents. Prior to the pharmacological review, the mean number of chronic medications prescribed per resident was 6.63 (SD 2.93) and after this review it was 4.97 (SD 2.88). Polypharmacy decreased from 72.55% to 52.94% and excessive polypharmacy fell from 18.62% to 5.88%.The highest prevalence of IP was detected in people with a higher FI, in those identified as end-of-life, and also in more highly dependent residents (p < 0.05). Conclusions People who live in nursing homes have an advanced frailty. Establishing individualized therapeutic objectives with the application of the PCP model enabled to detect 92.2% of IP. People who are frailer, are functionally more dependent and those who are end-of-life are prescribed with inappropriate medication more frequently.

Heterogeneous ozone effects on the DNA methylome of bronchial cells observed in a crossover study.

We used a randomized crossover experiment to estimate the effects of ozone (vs. clean air) exposure on genome-wide DNA methylation of target bronchial epithelial cells, using 17 volunteers, each randomly exposed on two separated occasions to clean air or 0.3-ppm ozone for two hours. Twenty-four hours after exposure, participants underwent bronchoscopy to collect epithelial cells whose DNA methylation was measured using the Illumina 450 K platform. We performed global and regional tests examining the ozone versus clean air effect on the DNA methylome and calculated Fisher-exact p-values for a series of univariate tests. We found little evidence of an overall effect of ozone on the DNA methylome but some suggestive changes in PLSCR1, HCAR1, and LINC00336 DNA methylation after ozone exposure relative to clean air. We observed some participant-to-participant heterogeneity in ozone responses.

Superficial siderosis of the central nervous system in a patient with asymptomatic sacral paraganglioma as source of chronic bleeding. / Siderosis superficial del sistema nervioso central en una paciente con paraganglioma sacro asintomático como fuente de sangrado crónico.

INTRODUCTION: Superficial siderosis of the central nervous system is an infrequent pathology secondary to chronic bleeding into the cerebrospinal fluid. Spinal tumors are infrequent cause of superficial siderosis being ependymoma the most common etiology. CASE REPORT: We report the case of a woman with sensorineural hearing loss and cerebellar ataxia, diagnosed of superficial siderosis on brain MRI. She had no previous history of axial back pain or radicular leg pain or bowel or bladder incontinence. On spine MRI an intradural lesion was found at the S1 level. No signs of intratumoral hemorrhage were observed on MRI gradient-echo images. At surgery, an intradural soft mass with signs of chronic bleeding was completely resected. Based on microscopic examination and immunohistochemistry of the specimen, a diagnosis of paraganglioma World Health Organization grade I was made. CONCLUSIONS: Since the only proven treatment able to prevent further deterioration from superficial siderosis is to stop chronic bleeding into subarachnoid space, is of paramount importance to establish an early diagnosis of the source of bleeding. Cases of unexplained superficial siderosis of central nervous system should include routine spinal MRI to rule out bleeding of spinal tumor even in asymptomatic patients. Due to severity of potential deterioration caused by superficial siderosis, any tumoral lesion observed on spinal MRI even without documented sings of bleeding should be considered for resection.

TITLE: Siderosis superficial del sistema nervioso central en una paciente con paraganglioma sacro asintomático como fuente de sangrado crónico.Introducción. La siderosis superficial del sistema nervioso central es una patología poco frecuente secundaria al sangrado crónico en el líquido cefalorraquídeo. Los tumores medulares son causa poco habitual de siderosis superficial, y el ependimoma es la etiología más común. Caso clínico. Mujer con pérdida auditiva neurosensorial y ataxia cerebelosa, diagnosticada de siderosis superficial en la resonancia magnética cerebral. No tenía antecedentes de dolor raquídeo axial, dolor radicular ni incontinencia esfinteriana. En la resonancia magnética de la columna se encontró una lesión intradural en S1. No se observaron signos de hemorragia intratumoral en las secuencias de resonancia magnética en eco de gradiente. En la cirugía, se apreció una masa blanda intradural con signos de sangrado crónico que se resecó. Basado en el examen microscópico e inmunohistoquímico de la muestra, se alcanzó el diagnóstico de paraganglioma de grado I de la Organización Mundial de la Salud. Conclusiones. Dado que el único tratamiento probado capaz de prevenir un mayor deterioro por la siderosis superficial es detener el sangrado crónico en el espacio subaracnoideo, es importante establecer un diagnóstico temprano de la fuente de sangrado. Los casos no justificados de siderosis superficial del sistema nervioso central deben incluir una resonancia magnética de la columna rutinaria para descartar el sangrado de un tumor medular, incluso en pacientes asintomáticos. Debido a la gravedad del deterioro potencial causado por la siderosis superficial, cualquier lesión tumoral observada en una resonancia magnética del raquis, incluso sin presentar signos de sangrado, debería ser objeto de indicación quirúrgica.

La auscultación pulmonar en el siglo 21 / Lung auscultation in the 21th century

La auscultación pulmonar es parte fundamental del examen físico para el diagnóstico de las enfermedades respiratorias. La estandarización que ha alcanzado la nomenclatura de los ruidos respiratorios, sumado a los avances en el análisis computacional de los mismos, han permitido mejorar la utilidad de esta técnica. Sin embargo, el rendimiento de la auscultación pulmonar ha sido cuestionado por tener una concordancia variable entre profesionales de la salud. Aun cuando la incorporación de nuevas herramientas diagnósticas de imágenes y función pulmonar han revolucionado la precisión diagnóstica en enfermedades respiratorias, no existe tecnología que permita reemplazar la técnica de auscultación pulmonar para guiar el proceso diagnóstico. Por una parte, la auscultación pulmonar permite seleccionar a aquellos pacientes que se beneficiarán de una determinada técnica diagnóstica, se puede repetir cuantas veces sea necesario para tomar decisiones clínicas, y frecuentemente permite prescindir de exámenes adicionales que no siempre son fáciles de realizar o no se encuentran disponibles. En esta revisión se presenta el estado actual de la técnica de auscultación pulmonar y su rendimiento objetivo basado en la nomenclatura actual aceptada para los ruidos respiratorios, además de resumir la evidencia principal de estudios de concordancia de auscultación pediátrica y su análisis objetivo a través de nueva tecnología computacional.

Lung auscultation is an essential part of the physical examination for diagnosing respiratory diseases. The terminology standardization for lung sounds, in addition to advances in their analysis through new technologies, have improved the use of this technique. However, traditional auscultation has been questioned due to the limited concordance among health professionals. Despite the revolu tionary use of new diagnostic tools of imaging and lung function tests allowing diagnostic accuracy in respiratory diseases, no technology can replace lung auscultation to guide the diagnostic process. Lung auscultation allows identifying those patients who may benefit from a specific test. Moreover, this technique can be performed many times to make clinical decisions, and often with no need for- complicated and sometimes unavailable tests. This review describes the current state-of-the-art of lung auscultation and its efficacy based on the current respiratory sound terminology. In addition, it describes the main evidence on respiratory sound concordance studies among health professionals and its objective analysis through new technology.
