Parental Assessment of Infantile Hemangioma Cosmetic Clinical Outcomes: Results of the Spanish Hemangioma Nationwide Prospective Cohort.

BACKGROUND: Functional impairment is the main consideration when it comes to choosing therapy for infantile hemangiomas (IH). However, since most hemangiomas are treated for cosmetic reasons, it is important to know the cosmetic outcome assessed by the parents. OBJECTIVE: To evaluate the aesthetic outcomes of IH, considering the characteristics of the lesions and the treatments used. PATIENTS AND METHODS: The Spanish Infantile Hemangioma Nationwide Prospective Cohort (2016-2022) recruited all consecutive patients diagnosed with IH in 12 Spanish hospitals. The children included had two photos of the IH lesion (at both baseline and at the end of the study). A panel of parents blindly assessed all available photos using a scale from 0 (worst cosmetic outcomes) to 10 (best cosmetic outcomes). The different scores - both before and after treatment - as well as the outcomes percent considered excellent (>9) were described and compared. We analyzed the effect of receiving different therapies and performed causal model analyses estimating the mean treatment effect of parents' assessments. RESULTS: The median follow-up was 3.1 years. A total of 824 photos were evaluated. Baseline aesthetic impact was higher in the propranolol group vs the topical timolol and observation treatment groups (1.85 vs 3.14 vs 3.66 respectively; p<0.001). After treatment, the aesthetic impact was similar between both treatment groups (7.59 vs 7.93 vs 7.90; p>0.2). The causal model could only be applied to the comparison between topical timolol and observation, revealing no differences whatsoever. CONCLUSION: This is the first prospective cohort to analyze the aesthetic outcome of IH. The final aesthetic results of the three therapies were similar, with nearly 40% of patients achieving excellent aesthetic outcomes.

Moral injury and pre-deployment personality factors as contributors to psychiatric symptomatology among combatants: a two-year prospective study.

Background: Combatants who are exposed to events that transgress deeply held moral beliefs might face lasting psychopathological outcomes, referred to as Moral Injury (MI). However, knowledge about pre-deployment factors that might moderate the negative consequences of MI is sparse. In this prospective study, we examined pre-enlistment characteristics and pre-deployment personality factors as possible moderators in the link between exposure to potentially morally injurious events (PMIEs) and psychiatric symptomatology among Israeli active-duty combatants.Methods: A sample of 335 active-duty Israeli combatants participated in a 2.5-year prospective study with three waves of measurements (T1: 12 months before enlistment, T2: Six months following enlistment - pre-deployment, and T3: 18 months following enlistment - post-deployment). Participants' characteristics were assessed via semi-structured interviews (T1) and validated self-report measures of personality factors: emotional regulation, impulsivity, and aggression (T2) and combat exposure, PMIEs, psychiatric symptomology and posttraumatic symptoms (T3) between 2019 and 2021.Results: Pre-enlistment psychiatric difficulties and negative life events contributed to higher exposure to PMIEs post-deployment. Higher levels of pre-deployment aggression and lower levels of emotional regulation and impulsivity moderated the association between betrayal, PMIEs and psychiatric symptomology post-deployment, above and beyond pre-enlistment psychiatric difficulties and life events.Conclusions: Our results highlight that pre-deployment emotional regulation, impulsivity and aggressiveness levels should be assessed, screened, and identified among combatants, as they all facilitate psychiatric symptomology (and PTSS) after combatants are exposed to PMIEs of betrayal. Such pre-assessment will enable the identification of at-risk combatants and might provide them with tailor-made preparation regarding moral and ethical situations that should be investigated in future research.

Pre-enlistment psychiatric difficulties contributed to higher exposure to PMIEs post-deployment.Pre-deployment personality moderated the associations between PMIEs and psychiatric symptomatology among combatants.Higher levels of pre-deployment emotional regulation moderated the association between betrayal PMIEs and post-deployment PTSS symptoms.

Comparison of hemodynamic and respiratory outcomes between two surgical positions for percutaneous nephrolithotomy: a prospective, randomized clinical trial.

INTRODUCTION: Percutaneous nephrolithotomy (PCNL) has become the gold standard for the treatment of large and complex kidney stones. OBJECTIVES: The objective of this study is to evaluate the efficacy and safety of percutaneous nephrolithotomy (PCNL) for patients in the flank position versus prone position. METHODS: In our prospective randomized trial, 60 patients who would undergo fluoroscopy and ultrasound-guided PCNL in prone or flank position were divided into two groups. Demographic features, hemodynamics, respiratory and metabolic parameters, postoperative pain scores, analgesic requirements, amount of fluid given, blood loss and transfusion, duration of operation and hospital stay, and perioperative complications were compared. RESULTS: PaO2, SaO2, SpO2 and Oxygen Reserve Index (ORi) at the 60th minute of the operation and in the postoperative period, Pleth Variability index (PVi) at the 60th minute of the operation, driving pressure in all time periods and the amount of bleeding during the operation were determined to be statistically significantly higher in the prone group. There was no difference between the groups in terms of other parameters. Was found to be statistically significantly higher in the prone group. CONCLUSIONS: Due to our results the flank position can be preferred in PCNL operations, considering that the position should be chosen according to the surgeon's experience, the patient's anatomical and physiological data, positive effects on respiratory parameters and bleeding, and the operation time can be shortened as the experience increases.

Physical violence against children with disabilities: A Danish national birth cohort prospective study.

Background: Children with disabilities are at heightened risk of violence compared to their non-disabled peers. However, extant research suffers from several limitations, focusing on child abuse and one or few types of disability, ignoring conventional violent crimes.Objective: The aim was to assess 10 disabilities and to examine whether different disabilities vary in their risk of criminal victimization.Method: Using the Danish Psychiatric Case Register, the Criminal Register, and other population-based registers, we included nine birth cohorts (n = 570,351) and followed them until 18 years of age. We compared children exposed to violence with non-exposed children. We estimated odds ratios (ORs) for the disabilities and adjusted the ORs for several risk factors.Results: We identified 12,830 cases of reported violence (2.25% of the population) towards children and adolescents. Children with disabilities were overrepresented, as were boys and ethnic minorities. After controlling for risk factors, four disabilities had heightened risk for criminal violence: attention-deficit hyperactivity disorder (ADHD), brain injury, speech, and physical disabilities. When we compared risk factors controlling for the various disabilities, parental history of violence, family break-up, out-of-home placement, and parental unemployment contributed especially to the violence, while parental alcohol/drug abuse was no longer a predictor. Having several disabilities increased the risk of violence.Conclusions: Criminal victimization of children and adolescents with specific disabilities was common. However, compared to the previous decade, a considerable reduction of one-third has taken place. Four risk factors contributed particularly to the risk of violence; therefore, precautions should be taken to further reduce the violence.

Based on data from nine full birth cohorts, followed for 18 years, the study concludes that disabled children are considerably more exposed to police-reported physical violence than non-disabled children.Four disabilities were especially exposed to physical violence when we controlled for risk factors.Four risk factors contributed particularly to physical violence when we controlled for diagnoses.

Results of the Spanish National Polytrauma Registry. Where are we and where are we heading?

INTRODUCTION: In 2017, the Spanish National Polytrauma Registry (SNPR) was initiated in Spain with the goal to improve the quality of severe trauma management and evaluate the use of resources and treatment strategies. The objective of this study is to present the data obtained with the SNPR since its inception. METHODS: We conducted an observational study with prospective data collection from the SNPR. The trauma patients included were over 14 years of age, with ISS ≥ 15 or penetrating mechanism of injury, from a total of 17 tertiary hospitals in Spain. RESULTS: From 1/1/17 to 1/1/22, 2069 trauma patients were registered. The majority were men (76.4%), with a mean age of 45 years, mean ISS 22.8, and mortality 10.2%. The most common mechanism of injury was blunt trauma (80%), the most frequent being motorcycle accident (23%). Penetrating trauma was presented in 12% of patients, stab wounds being the most common (84%). On hospital arrival, 16% of patients were hemodynamically unstable. The massive transfusion protocol was activated in 14% of patients, and 53% underwent surgery. Median hospital stay was 11 days, while 73.4% of patients required intensive care unit (ICU) admission, with a median ICU stay of 5 days. CONCLUSIONS: Trauma patients registered in the SNPR are predominantly middle-aged males who experience blunt trauma with a high incidence of thoracic injuries. Early addressed detection and treatment of these kind of injuries would probably improve the quality of trauma care in our environment.

BIOBADATOP Spanish Atopic Dermatitis Registry: Description and Early Findings. / BIOBADATOP: Registro Español de Dermatitis Atópica. Descripción y primeros resultados.

BACKGROUND: In recent years, remarkable improvements in our understanding of atopic dermatitis (AD) have revolutionized treatment perspectives, but access to reliable data from clinical practice is essential. MATERIALS AND METHOD: The Spanish Atopic Dermatitis Registry, BIOBADATOP, is a prospective, multicenter database that collects information on patients of all ages with AD requiring systemic therapy with conventional or novel drugs. We analyzed the registry to describe patient characteristics, diagnoses, treatments, and adverse events (AEs). RESULTS: We studied data entries for 258 patients who had received 347 systemic treatments for AD. Treatment was discontinued in 29.4% of cases, mostly due to a lack of effectiveness (in 10.7% of cases). A total of 132 AEs were described during follow-up. Eighty-six AEs (65%) were linked to a systemic treatment, most commonly dupilumab (39AEs) and cyclosporine (38AEs). The most common AEs were conjunctivitis (11patients), headache (6), hypertrichosis (5), and nausea (4). There was 1severe AE (acute mastoiditis) associated with cyclosporine. CONCLUSIONS: Initial findings on AEs from the Spanish BIOBADATOP registry are limited by short follow-up times precluding comparisons or calculation of crude and adjusted incidence rates. At the time of our analysis, no severe AEs had been reported for novel systemic therapies. BIOBADATOP will help answer questions on the effectiveness and safety of conventional and novel systemic therapies in AD.

Association of the triglyceride-glucose index with the occurrence of non-alcoholic fatty liver disease and mortality in elderly inpatients: a prospective observational study.

Introduction: Introduction: non-alcoholic fatty liver disease (NAFLD) is a disease in which there is excessive fat deposition in hepatocytes due to hepatoprotective factors. Objectives: to assess the association of the triglyceride-glucose index with the occurrence of non-alcoholic fatty liver disease and mortality in elderly inpatients. To identify the TyG index as a predictive factor of NAFLD. Methods: this prospective observational study included elderly inpatients admitted to the Department of Endocrinology at the Linyi Geriatrics Hospital, Affiliated to Shandong Medical College, between August 2020 and April 2021. The TyG index was calculated according to an established formula: TyG = Ln [triglycerides (TG) (mg/dl) × Fasting plasma glucose (FPG) (mg/dl) / 2]. Result: a total of 264 patients were enrolled, with 52 (19.7 %) cases occurred NAFLD. Multivariate logistic regression analysis showed that TyG (OR = 3.889; 95 % CI: 1.134-11.420; p = 0.014) and ALT (OR = 1.064; 95 % CI: 1.012-1.118; p = 0.015) were independently associated with the occurrence of NAFLD. Furthermore, receiver operating characteristic (ROC) curve analysis showed that the area under the curve (AUC) of TyG was 0.727, with sensitivity = 80.4 % and specificity = 57.8 % at cut off = 8.71. A Cox proportional hazards regression model showed that, after adjusting for age, sex, smoking, drinking, hypertension, and type 2 diabetes, TyG > 8.71 (HR = 3.191; 95 % CI: 1.347 to 7.560; p < 0.001) was an independent risk factor for mortality in the elderly. Conclusions: the TyG index can predict non-alcoholic fatty liver disease and mortality in elderly Chinese inpatients.

Introducción: Introducción: la enfermedad del hígado graso no alcohólico (EHGNA) es una enfermedad en la que una cantidad excesiva de grasa se acumula en los hepatocitos debido a factores hepatoprotectores. Objetivos: evaluar la asociación entre el índice glucemia-triglicéridos con la presencia de hígado graso no alcohólico (EHGNA) y mortalidad en pacientes hospitalizados de avanzada edad. Identificar el índice TyG como factor predictivo de la EHGNA. Métodos: este estudio observacional y prospectivo incluyó a pacientes de avanzada edad hospitalizados en el Departamento de Endocrinología del Hospital de Geriatría de Linyi, Afiliado al Colegio Médico de Shandong, entre agosto de 2020 y abril de 2021. El índice TyG se calculó según una fórmula establecida: TyG = Ln [triglicéridos (TG) (mg/dl) × Glucosa en sangre en ayunas (FPG) (mg/dl) / 2]. Resultado: se incluyeron 264 pacientes, con 52 (19,7 %) casos de EHGNA. El análisis de regresión logística multivariante mostró que el TyG (razón de momios (OR) = 3,889; intervalo de confianza del 95 %: 1,134-11,420; p = 0,014) y ALT (razón de momios (OR) = 1,064; intervalo de confianza del 95 %: 1,012-1,118; p = 0,015) se asociaban de forma independiente con la aparición de EHGNA. Además, el análisis de la curva de características operativas del receptor (ROC) mostró que el área bajo la curva (AUC) de TyG era de 0,727, con una sensibilidad del 80,4 % y una especificidad del 57,8 % en el punto de corte de 8,71. El modelo de regresión de riesgos proporcionales de Cox mostró que, tras ajustar por edad, sexo, tabaquismo, consumo de alcohol, hipertensión y diabetes tipo 2, un TyG > 8,71 (HR = 3,191; intervalo de confianza del 95 %: 1,347 a 7,560; p < 0,001) era un factor de riesgo independiente de mortalidad para los paciente de edad avanzada. Conclusiones: el índice TyG puede predecir la enfermedad del hígado graso no alcohólico y la mortalidad en pacientes chinos hospitalizados de avanzada edad.

Disfunção hepática em pacientes de unidade de terapia intensiva médica prevê desfecho desfavorável / Hepatic dysfunction in medical intensive careunit patients predicts poor outcome

ABSTRACT Background: A large number of patients admitted to the medical intensive care unit (MICU) have abnormal liver function tests (LFT). This includes patients with critical illness with or without preexisting liver disease and patients with acute primary liver injury. There are very few studies which have investigated the spectrum of liver disease, clinical profile and outcome in patients admitted to the MICU. Objective To evaluate the occurrence, etiology, clinical profile, laboratory profile and outcome of hepatic dysfunction in patients admitted to the MICU. To evaluate the utility of model for end-stage liver disease (MELD) score on admission as a predictor of adverse short term outcome in patients with hepatic dysfunction admitted in MICU. Methods: It was a prospective observational study, conducted from December 2017 to December 2018 in a tertiary care hospital. Two hundred and two patients admitted to the MICU with LFTs as per the inclusion criteria were analyzed and their short-term outcome at 7 days was studied in relation to various parameters. Results: LFT abnormalities were present in 202/1126 (17.9%) of the patients admitted to MICU. Critical illness associated liver dysfunction was found in 172 (85.2%) patients, chronic liver disease in 11 (5.4%) patients and acute viral hepatitis in 19 (9.4%) patients. Most common symptom was fever (68.3%) followed by vomiting (48.0%). Among LFT abnormalities, elevated transaminases, raised international normalized ratio and high MELD score on admission correlated with poor short-term outcome. Requirement for inotropes and mechanical ventilation correlated with poor short-term outcome. Mortality did not differ significantly between patients with chronic liver disease, patients with acute viral hepatitis and patients with critical illness associated hepatic dysfunction. Hepatic dysfunction in MICU was associated with poor outcome and a high short-term mortality of 56.4% (114/202). Conclusion: Liver function abnormality is common in patients who are admitted to the MICU and its presence is an indicator of poor short-term outcome.

RESUMO Contexto: Um grande número de pacientes internados na unidade de terapia intensiva (UTI) tem testes de função hepática anormais (TFH). Isso inclui pacientes com doença crítica com ou sem doença hepática pré-existente e pacientes com lesão hepática primária aguda. Há poucos estudos que têm investigado o espectro da doença hepática, perfil clínico e desfecho em pacientes admitidos em UTI. Objetivo Avaliar a ocorrência, etiologia, perfil clínico, perfil laboratorial e desfecho de disfunção hepática em pacientes internados na UTI médica. Avaliar a utilidade do modelo para doença hepática em estágio terminal (MELD). Escore na admissão como preditor de desfecho adverso a curto prazo em pacientes com disfunção hepática admitida em UTI. Métodos: Foi realizado um estudo observacional prospectivo, de dezembro de 2017 a dezembro de 2018 em um hospital de atenção terciária. Foram analisados 202 pacientes internados na UTI com TFH conforme os critérios de inclusão e seu desfecho a curto prazo de 7 dias foi estudado em relação a diversos parâmetros. Resultados: Anormalidades dos testes estiveram presentes em 202/1126 (17,9%) dos pacientes internados na UTI. Doença crítica associada à disfunção hepática foi encontrada em 172 (85,2%) pacientes, doença hepática crônica em 11 (5,4%) pacientes e hepatite viral aguda em 19 (9,4%) pacientes. O sintoma mais comum foi a febre (68,3%), seguido de vômito (48,0%) casos. Entre as anormalidades do TFH, transaminases elevadas, INR e escore MELD elevados na admissão correlacionaram-se com desfecho ruim de curto prazo. Exigência de inotrópicos e ventilação mecânica correlacionaram-se com desfecho de curto prazo ruim. A mortalidade não diferiu significativamente entre pacientes com doença hepática crônica, pacientes com hepatite viral aguda e pacientes com doença crítica associada à disfunção hepática. A disfunção hepática em UTI esteve associada a um desfecho ruim e à uma alta mortalidade a curto prazo de 114/202 (56,4%). Conclusão: A anormalidade da função hepática é comum em pacientes que são admitidos nas unidades de tratamento intensivo e sua presença é um indicador de desfecho de curto prazo ruim.

Análise dos modelos de pagamento aplicados ao financiamento federal na perspectiva do Sistema Único de Saúde / Analysis of payment models applied to federal funding from the perspective of the Brazilian Health System

Objetivo: Este estudo tem por objetivo identificar os modelos de pagamento existentes no Sistema Único de Saúde referentes aos repasses federais para a Atenção Primária à Saúde (APS) e a Atenção Especializada à Saúde. Métodos: Foi realizado um estudo quantitativo e analítico, desenvolvido em três etapas: levantamento de todos os tipos de repasse da União; classificação de cada categoria de repasse segundo os tipos de modelos de pagamentos; e mensuração da participação de cada modelo de pagamento, de acordo com os componentes de financiamento analisados, em relação aos valores líquidos repassados. Resultados: Os repasses federais foram classificados em sete modelos de pagamentos. Para a APS, em 2020, foram apurados R$ 21,7 bilhões, aproximadamente, incluindo os recursos destinados para a pandemia, e R$ 20,9 bilhões, sem considerar os recursos para enfrentamento da pandemia de COVID-19. Mais de 50% dos valores empregados foram classificados como capitação, em ambos os casos. Para a Atenção Especializada à Saúde, em 2019, foram computados em torno de R$ 48,5 bilhões e, em 2020, acima de R$ 49,2 bilhões. Para os dois anos, mais de 70% dos recursos foram destinados a pagamentos por procedimento. Conclusões: Este estudo permitiu a ampliação do conhecimento sobre a alocação dos recursos referentes aos repasses da União para estados, Distrito Federal e municípios. Como os modelos de pagamentos estão relacionados com a produtividade, acesso e qualidade do serviço de saúde, conhecer as formas de pagamento e identificar a mais adequada para cada situação contribui para o alcance das metas e para a mitigação de eventuais perdas de eficiência nos sistemas de saúde.

Objective: This study aims at identifying the payment methods existing in the Unified Health System referring to federal transfers to Primary Health Care (PHC) and Specialized Health Care. Methods: A quantitative and analytical study was carried out, developed in three stages: survey of all types of transfers from the Union; classification of each transfer category according to the types of payment methods and measurement of the participation of each payment methods, according to the financing components analyzed, in relation to the net values transferred. Results: Federal transfers were classified into seven payment methods. For PHC, in 2020, approximately R$ 21.7 billion was calculated, including resources destined for the pandemic, and R$ 20.9 billion without considering resources to face the COVID-19 pandemic. More than 50% of the amounts used were classified as capitation, in both cases. For specialized health care, in 2019, around R$ 48.5 billion were calculated, and in 2020 more than R$ 49.2 billion. For the two years, more than 70% of the funds were allocated to fee for service. Conclusions: This study allowed for an expansion in knowledge about the allocation of resources referring to transfers from the Union to states, the Federal District and municipalities. As the payment methods are related to productivity, access and quality of the health service, knowing and identifying the most appropriate payment methods for each situation contributes to the achievement of the goals and to the mitigation of eventual losses of efficiency in the healthcare systems.

Cardiac amyloidosis: Description of a series of 143 cases. / Amiloidosis cardiaca: descripción de una serie de 143 casos.

INTRODUCTION AND OBJECTIVES: Recently, there have been important advances in the diagnosis and treatment of cardiac amyloidosis (CA). Our aim was to provide an updated description of its 2 most frequent types: the transthyretin CA (ATTR-CA) and the light chain CA (AL-CA). METHODS: Prospective registry of patients with CA diagnosed in 7 institutions in Galicia (Spain) between January 1, 2018 and June 30, 2020. Variables related to clinical characteristics, complementary tests, survival and causes of death were collected. RESULTS: One hundred and forty-three patients with CA were consecutively included, 128 ATTR-CA (89.5%) and 15 AL-CA (10.5%). Mean age was 79.6±7.7 years and 23.8% were women. Most patients with ATTR-CA were diagnosed non-invasively (87.5%). On physical examination, 35.7, 35 and 7% had Popeye's sign, Dupuytren's contracture and macroglossia, respectively. Twelve-month and 24-month survival was 92.1 and 76.2% in the ATTR-CA group, and 78.6 and 61.1% in the AL-CA group (P=.152). The cause of death was cardiovascular in 80.8% of the cohort. CONCLUSIONS: ATTR-CA can be diagnosed non-invasively in most cases and it is the most common type of CA in routine clinical practice. Furthermore, an increase in the short-term survival of CA appears to be observed, which could be due to advances related to its diagnosis and treatment.

Effectiveness and safety of tacrolimus treatment for IgA nephropathy: A prospective cohort study.

BACKGROUND: There is no a unified opinion in the treatment of IgA nephropathy. This prospective cohort study was to explore the effectiveness and safety of tacrolimus for treatment of IgA (Immunoglobulin A) nephropathy patients. METHODS: In this study, we assigned 50 patients with biopsy-proven IgA nephropathy in a 1:1.5 ratio to receive oral tacrolimus or full-dose glucocorticoid for 6 months. All the patients had 24-h urine protein excretion≥2.0g/24h and estimated glomerular filtration rate≥50mL/min/1.73m2. Primary endpoint was rate of complete remission. RESULTS: After 6 months of treatment, seven participants achieved complete remission in the tacrolimus group and twelve participants in the glucocorticoid group, the complete remission rate was 35% and 40%, respectively. There were not significantly differences between two groups (P=0.7). However, the serum creatinine level from baseline was an increase of 13±13.5µmol/L in the tacrolimus group and a decrease of 8.2±20µmol/L in the glucocorticoid group. When patients stopped taking tacrolimus for 3 months, creatinine level can almost fall to normal level. Thus, patients with renal insufficiency have a high incidence in the tacrolimus group. CONCLUSIONS: Tacrolimus was noninferior to full-dose glucocorticoid in inducing proteinuria remission at 6 months. This suggested that those IgA nephropathy patients who are unwilling to full-dose glucocorticoid could consider tacrolimus, but need to pay attention to the impact on renal function.

Nutritional status assessment in Alzheimer disease and its influence on disease progression.

INTRODUCTION: Nutritional deficiencies are frequent in Alzheimer disease (AD), even in early stages. Nutritional impairment (NI) may be associated with faster disease progression. The objective of this study was to describe the frequency of NI and the associated risk factors at the time of diagnosis and to analyse its influence on subsequent progression. METHODS: We performed a prospective, multicentre, observational study of patients recently diagnosed with prodromal AD (pAD) or dementia due to AD (ADd). Two clinical assessments were conducted over a period of 18 months. The Mini Nutritional Assessment test (MNA; score range, 0-30; cut-off point for NI, < 24) was used to estimate nutritional status. Progression was defined as an increase of ≥ 3 points on the Clinical Dementia Rating-sum of boxes test. RESULTS: The sample included 50 patients with pAD (mean [standard deviation] age, 76.1 [5.3] years; 68% women), and 127 with ADd (80 [5.9] years; 72.4% women). A total of 141 (79.7%) completed both evaluations. The prevalence of NI was 28.2% (24% for pAD, 29.9% for ADd; P = .43), with the majority (92%) at risk of malnutrition. NI was associated with female sex (odds ratio [OR]: 4.2; 95% confidence interval [CI]: 1.7-10.5; P < .001) and greater behavioural involvement (OR: 5.8; 95% CI: 2.6-12.7; P < .001). A larger proportion of patients with progression was observed among those with NI than among those with normal nutritional status (50% vs 28.7%, P < .05; ADd: 53.6% vs 31.8%, P < .05; pAD: 41.7% vs 22.9%, P = .21). Greater cognitive impairment (OR: 2.1; 95% CI: 1.03-4.4; P < .05) and NI (OR: 2.4; 95% CI: 1.1-5.1; P < .05) were independent risk factors for disease progression. CONCLUSIONS: NI is highly prevalent in patients with AD. Assessing nutritional status at the time of diagnosis may enable identification of patients at greater risk of disease progression.

O impacto da romoendoscopia com aprimoramento da imagem na taxa de perda de adenoma na colonoscopia de rastreio / The impact of colorectal chromendoscopy with enhanced mucosal imaging on adenoma miss rate in screening colonoscopy

ABSTRACT BACKGROUND: Colonoscopy is the gold standard for the diagnosis and treatment of adenomas. It is related with decreased colorectal cancer incidence and mortality. However, an important problem is missed colorectal adenoma. All efforts should be undertaken to reduce this rate. Enhancing imaging technologies including electronic chromoendoscopy and magnification has been increasingly adopted for improving the colorectal neoplasia detection rate and the detailed study of its surface, as well. I-scan images (Pentax, Tokyo, Japan) provides virtual chromoendoscopy in real-time during the examination to view the surface pattern, highlighting the microvasculature of the neoplastic lesion. The evidence on the impact of the use of I-scan on the colorectal adenoma detection rate is scarce. OBJECTIVE: To evaluate whether the use of I-scan has impact on the adenoma miss rate (AMR) of screening colonoscopy exams. METHODS: Observational and prospective study conducted by monitoring patients over 50 years undergoing colonoscopy. There were two groups: Group 1 - first inspection with standard high-definition white-light (HDWL) followed by a second inspection with I-scan 1; Group 2 - first inspection with I-scan 1 followed by a second inspection with standard HDWL. The primary outcome was the AMR from the first exam, calculated with the number of adenomas detected in the second exam, divided by the total number of adenomas detected in both exams. RESULTS: A total of 85 patients participated in the study. 14 were excluded, with a final sample of 71 patients, in the Group 1, 34 patients, and the Group 2, 37. A total of 58 adenomas were detected, 40 in the first inspection (20 in each group) and 18 in the second inspection in group 1. The overall AMR was higher for the Group 1 than the Group 2 (47.4% vs 0% P=0.0002). CONCLUSION: The use of I-scan 1 during colonoscopy exam reduces the AMR.

RESUMO CONTEXTO: O câncer colorretal é uma das principais causas de morte relacionada ao câncer em todo o mundo. A colonoscopia é o padrão ouro para diagnosticar e tratar lesões precoces, levando à diminuição da incidência e mortalidade do câncer colorretal. Entretanto, é importante o reconhecimento de que alguns adenomas podem não ser detectados (adenomas perdidos) durante o exame, e todos os esforços vêm sendo destinado a reduzir esta taxa. O aprimoramento das tecnologias de imagem, incluindo cromoendoscopia eletrônica e ampliação, tem sido cada vez mais adotado para melhorar a taxa de detecção de adenomas colorretais. Como exemplo, as imagens obtidas com o I-scan® (Pentax, Tóquio, Japão), que fornecem cromoendoscopia virtual em tempo real durante o exame para visão do padrão de superfície, destacando a microvasculatura da lesão detectada. As evidências sobre o impacto do uso do I-scan® na taxa de detecção de adenoma colorretal são escassas. OBJETIVO: Avaliar se o uso de imagens I-scan® (Pentax, Tóquio, Japão) tem impacto na taxa de perda de adenoma nas colonoscopias de triagem. MÉTODOS: Estudo observacional prospectivo de colonoscopias comparando cromoscopia com o aprimoramento de superfície e luz-branca. Pacientes acima de 50 anos submetidos à colonoscopia foram alocados aleatoriamente em dois grupos usando randomização eletrônica - Grupo 1: primeira inspeção com luz branca de alta definição seguida por uma segunda inspeção com o aprimoramento de superfície pelo I-scan 1®; Grupo 2: primeira inspeção com o aprimoramento de superfície I-scan 1® seguida de uma segunda inspeção com luz branca de alta definição. O desfecho primário foi a taxa de perda de adenomas do primeiro exame, calculado com o número de adenomas detectados na segunda inspeção do exame dividido pelo número total de adenomas detectados em ambas inspeções. RESULTADOS: Participaram do estudo 85 pacientes, sendo excluídos 14, com amostra final de 71 pacientes. 34 foram alocados para o Grupo 1 e 37 no Grupo 2. Um total de 58 adenomas foram detectados, 40 na primeira inspeção (20 em cada grupo) e 18 na segunda inspeção, somente no Grupo 1. A taxa de perda de adenoma foi maior para o Grupo 1 do que para o Grupo 2 (47,4% vs 0% P=0,0002). CONCLUSÃO: A utilização de aprimoramento de superfície I-scan 1 reduz a taxa de perda de adenomas em exames colonoscópios.

Latin-American Ambulatory Blood Pressure Registry (MAPA-LATAM): An urgent need.

Hypertension (HT) is one of the main risk factors for cardiovascular disease (CVD). Although it is a global problem, independently of economic situation, region, race or culture, the data available on Latin America are limited. Clinical guidelines emphasise the importance of obtaining reliable blood pressure readings. For this reason, the use of ambulatory blood pressure monitoring (ABPM) is recommended. This improves precision and reproducibility, resulting in better diagnosing and therapeutic decision-making, and constitutes a better estimation of prognosis than office measurements. Unfortunately, there is no global prospective ABPM registry for all of Latin America that analyses HT prevalence, the level of knowledge about it, treatment percentage and the degree of control. Consequently, the authors of this article consider its implementation a priority.

Nutritional status assessment in Alzheimer disease and its influence on disease progression. / Evaluación del estado nutricional en la enfermedad de Alzheimer y su influencia en la progresión tras el diagnóstico.

INTRODUCTION: Nutritional deficiencies are frequent in Alzheimer disease (AD), even in early stages. Nutritional impairment (NI) may be associated with faster disease progression. The objective of this study was to describe the frequency of NI and the associated risk factors at the time of diagnosis and to analyse its influence on subsequent progression. METHODS: We performed a prospective, multicentre, observational study of patients recently diagnosed with prodromal AD (pAD) or dementia due to AD (ADd). Two clinical assessments were conducted over a period of 18months. The Mini Nutritional Assessment test (MNA; score range, 0-30; cut-off point for NI, <24) was used to estimate nutritional status. Progression was defined as an increase of ≥3points on the Clinical Dementia Rating-sum of boxes test. RESULTS: The sample included 50 patients with pAD (mean [standard deviation] age, 76.1 [5.3] years; 68% women), and 127 with ADd (80 [5.9] years; 72.4% women). A total of 141 (79.7%) completed both evaluations. The prevalence of NI was 28.2% (24% for pAD, 29.9% for ADd; P=.43), with the majority (92%) at risk of malnutrition. NI was associated with female sex (odds ratio [OR]: 4.2; 95% confidence interval [CI]: 1.7-10.5; P<.001) and greater behavioural involvement (OR: 5.8; 95%CI: 2.6-12.7; P<.001). A larger proportion of patients with progression was observed among those with NI than among those with normal nutritional status (50% vs 28.7%, P<.05; ADd: 53.6% vs 31.8%, P<.05; pAD: 41.7% vs 22.9%, P=.21). Greater cognitive impairment (OR: 2.1; 95%CI: 1.03-4.4; P<.05) and NI (OR: 2.4; 95%CI: 1.1-5.1; P<.05) were independent risk factors for disease progression. CONCLUSIONS: NI is highly prevalent in patients with AD. Assessing nutritional status at the time of diagnosis may enable identification of patients at greater risk of disease progression.

One-year adolescent bone mineral density and bone formation marker changes through the use or lack of use of combined hormonal contraceptives / Alterações na densidade mineral óssea e nos marcadores de formação óssea em adolescentes usuárias ou não de contraceptivos hormonais orais combinados por período de um ano

Abstract Objective: The objective of this study was to evaluate the effects of two low-dose combined oral contraceptives on bone metabolism in adolescents for one year. Methods: This was a quasi-experimental study. The adolescents were divided into three groups: oral contraceptives 1 (n = 42) (20 µg EE/150 µg desogestrel), oral contraceptives 2 (n = 66) (30 µg EE/3 mg drospirenone), and a control group (n = 70). Adolescents underwent anthropometric assessment and densitometry (dual-energy X-ray). Bone age and bone formation markers (osteocalcin and bone alkaline phosphatase) were evaluated. The oral contraceptives users were evaluated again after 12 months. Linear regression analysis was used to indirectly study the effect of each additional year of chronological age on anthropometric and densitometric variables as well as on bone markers in the control group. Results: At study entry, no significant differences were observed between the oral contraceptives 1, oral contraceptives 2, and controls in the analyzed variables. Linear regression analysis showed an increase in bone mineral density and bone mineral content for each additional year. There was a significant reduction in bone alkaline phosphatase levels; no significant difference was observed for osteocalcin in control individuals. Comparison of dual-energy X-ray variables at baseline and after one year showed no significant differences in the oral contraceptives 1 or oral contraceptives 2 groups. A significant reduction in bone alkaline phosphatase and osteocalcin levels was observed in both the oral contraceptives 1 and oral contraceptives 2 groups. Conclusion: Adolescent women gain peak bone mass during this phase of life. Two low-dose combined oral hormonal contraceptives were associated with lower bone gain and lower bone formation markers than in untreated controls.

Resumo: Objetivo: O objetivo deste estudo foi avaliar os efeitos de dois contraceptivos orais combinados de baixa dosagem por um ano sobre o metabolismo ósseo em adolescentes. Métodos: Este foi um estudo quase experimental. As adolescentes foram divididas em três grupos: contraceptivos orais 1 (n = 42) (20 µg de EE/150 µg de desogestrel), contraceptivos orais 2 (n = 66) (30 µg EE/3 mg de drospirenona) e grupo controle (n = 70). As adolescentes foram submetidas à avaliação antropométrica e densitometria (raio-X de dupla energia). Foram avaliados a idade óssea e os marcadores de formação óssea (osteocalcina e fosfatase alcalina óssea). As usuárias de contraceptivos orais foram novamente avaliadas após 12 meses. A análise de regressão linear foi utilizada para estudar, indiretamente, o efeito de cada ano adicional da idade cronológica sobre as variáveis antropométricas e densitométricas e sobre os marcadores ósseos no grupo de controle. Resultados: No início do estudo, não foram observadas diferenças significativas nas variáveis analisadas entre as usuárias de contraceptivos orais 1, contraceptivos orais 2 e o grupo controle. A análise de regressão linear mostrou um aumento na densidade mineral óssea e no conteúdo mineral ósseo para cada ano adicional. Houve uma redução significativa nos níveis de fosfatase alcalina óssea e não foi observada diferença significativa para osteocalcina nos indivíduos controles. A comparação das variáveis do raio-X de dupla energia no início e após um ano não mostrou diferença significativa no grupo de contraceptivos orais 1 ou contraceptivos orais 2. Foi observada uma redução significativa nos níveis de fosfatase alcalina óssea e osteocalcina nos dois grupos contraceptivos orais 1 e contraceptivos orais 2. Conclusão: As adolescentes atingiram o pico de massa óssea durante essa fase da vida. Duas formulações de contraceptivos hormonais orais de baixa dosagem, após um ano de uso, se associaram a menor incremento na densidade mineral óssea e menor concentração de marcadores de formação óssea quando confrontados com resultados de adolescentes não usuárias de contraceptivos.

E-cigarette use and its association with smoking reduction and cessation intentions among Mexican smokers / Uso de cigarros electrónicos y su asociación con la reducción en el consumo de cigarros convencionales y la intención de dejar de fumar entre fumadores mexicanos

Abstract: Objective: Evaluate the patterns of e-cigarette use and their association with smoking behavior. Materials and methods: We analyzed data from a population-based representative cohort of adult smokers who participated in the International Tobacco Control Policy Evaluation Surveys in Mexico. The analytic sample (n=760) was restricted to participants who were followed up from wave 6 (2012) to wave 7 (2014-2015). GEE models regressed e-cigarette use at follow-up and changes in cigarettes per day (CPD) between waves, on baseline sociodemographic variables, smoking status (daily, non-daily, quit), e-cigarette trial, and quit intentions. Results: Smokers who were younger, had a higher income, and had tried e-cigarettes at baseline were more likely to be current e-cigarette users at follow-up. E-cigarette use at follow-up was not associated with a change in CPD over time. Conclusions: E-cigarette use does not appear to have promoted smoking cessation or reduction in this sample of Mexican smokers.

Resumen: Objetivo: Evaluar los patrones de uso de cigarros electrónicos y su asociación con el uso de tabaco. Material y métodos: Se usaron datos de una cohorte de fumadores adultos mexicanos de la Encuesta Internacional de Evaluación de Políticas del Control del Tabaco (n=760) con seguimiento de la ronda 6 (2012) a la 7 (2014-2015). Se usaron modelos GEE para evaluar el uso de cigarros electrónicos y el cambio en el número de cigarros por día (CPD) en variables de la basal sobre características sociodemográficas, consumo del cigarro (diario, no diario, haber dejado de fumar), prueba de cigarros electrónicos e intención de dejar de fumar. Resultados: Fumadores jóvenes, con ingresos altos y que probaron cigarros electrónicos en la medición basal tenían más posibilidad de usar cigarros electrónicos. No se encontró relación entre uso de cigarros electrónicos y cambio en CPD. Conclusiones: Los cigarros electrónicos no parecen promover el abandono ni la reducción del consumo de cigarros en esta muestra de fumadores mexicanos.
