RESUMO
BACKGROUND: There is a close relationship between obstructive sleep apnoea (OSA) and resistant hypertension (RH). However, studies assessing the long-term effect of diagnosing and treating OSA on blood pressure (BP) control in these patients are lacking. METHODS: To address this gap, we recruited 478 RH patients from hypertension units and followed them prospectively after they were screened for OSA through a sleep study. By performing 24-h ambulatory BP monitoring (ABPM) annually, the effect of OSA management was assessed. RESULTS: The patients had a median (interquartile range (IQR)) age of 64.0 (57.2-69.0)â years, 67% were males and most were nonsleepy, with a median (IQR) apnoea-hypopnoea index (AHI) of 15.8 (7.9-30.7)â events·h-1. The median (IQR) follow-up time was 3.01 (2.93-3.12)â years. At baseline, severe OSA was associated with uncontrolled BP, nocturnal hypertension and a nondipper circadian BP pattern. Moreover, these patients had higher BP values during follow-up than did patients in the other groups. However, among patients with moderate and severe OSA, the management of sleep disordered breathing, including the implementation of continuous positive airway pressure treatment, was associated with a reduction in 24-h ABPM parameters, especially night-time BP values, at the 1-year follow-up. These benefits were attenuated over time and only subjects with severe OSA maintained an ABPM night-time reduction at 3â years. Furthermore, clinical variables such as uncontrolled BP, sex and age showed a predictive value for the BP response at 1â year of follow-up. CONCLUSION: A favourable long-term decrease in BP was detected by diagnosing and treating OSA in a cohort of RH patients from hypertension units, but over time this decrease was only partially maintained in severe OSA patients.

Rationale: Obstructive sleep apnea (OSA) is associated with increased cardiovascular disease (CVD) risk. Conversely, OSA has not been shown to increase recurrent cardiovascular events in patients with acute coronary syndrome (ACS). This lack of homogeneity could suggest that the deleterious effect of OSA and its contribution to CVD could depend on specific patient profiles.Objectives: To evaluate the effect of OSA on cardiovascular risk for patients with different ACS phenotypes.Methods:Post hoc analysis of the ISAACC (Continuous Positive Airway Pressure in Patients with ACS and OSA) study, including 1,701 patients admitted for ACS (NCT01335087). To evaluate the presence of OSA (apnea-hypopnea index ≥ 15 events · h-1), all patients underwent polygraphy. Patients were followed up for a minimum period of 1 year. We performed nonsupervised clustering using latent class analysis to identify subgroups of patients on the basis of 12 clinical factors associated with cardiovascular risk. The effect of OSA on recurrent cardiovascular event risk was evaluated for each phenotype identified.Measurements and Main Results: Two phenotypes were identified: patients without previous heart disease and without previous ACS ("no-previous-CVD" phenotype; 81%) and patients with previous heart disease and previous ACS ("previous-CVD" phenotype; 19%). The median (interquartile range) at follow-up was 2.67 (3.8) years. For the no-previous-CVD phenotype, the effect of OSA showed an adjusted hazard ratio (95% confidence interval) of 1.54 (1.06-2.24; P value = 0.02), whereas for the previous-CVD phenotype, the effect of OSA showed an adjusted hazard ratio of 0.69 (0.46-1.04; P value = 0.08).Conclusions: For patients with ACS and a specific phenotype, OSA is associated with an increased risk of recurrent cardiovascular events. These patients are mainly characterized by no previous heart disease and admission for a first ACS occurrence.

BACKGROUND: Continuous positive airway pressure (CPAP) is an effective treatment for obstructive sleep apnea (OSA), but treatment compliance is often unsatisfactory. OBJECTIVE: The aim of this study was to assess the effectiveness and cost-effectiveness of an intelligent monitoring system for improving CPAP compliance. METHODS: This is a prospective, open label, parallel, randomized controlled trial including 60 newly diagnosed patients with OSA requiring CPAP (Apnea-Hypopnea Index [AHI] >15) from Lleida, Spain. Participants were randomized (1:1) to standard management or the MiSAOS intelligent monitoring system, involving (1) early compliance detection, thus providing measures of patient's CPAP compliance from the very first days of usage; (2) machine learning-based prediction of midterm future CPAP compliance; and (3) rule-based recommendations for the patient (app) and care team. Clinical and anthropometric variables, daytime sleepiness, and quality of life were recorded at baseline and after 6 months, together with patient's compliance, satisfaction, and health care costs. RESULTS: Randomized patients had a mean age of 57 (SD 11) years, mean AHI of 50 (SD 27), and 13% (8/60) were women. Patients in the intervention arm had a mean (95% CI) of 1.14 (0.04-2.23) hours/day higher adjusted CPAP compliance than controls (P=.047). Patients' satisfaction was excellent in both arms, and up to 88% (15/17) of intervention patients reported willingness to keep using the MiSAOS app in the future. No significant differences were found in costs (control: mean 90.2 (SD 53.14) (US $105.76 [SD 62.31]); intervention: mean 96.2 (SD 62.13) (US $112.70 [SD 72.85]); P=.70; 1=US $1.17 was considered throughout). Overall costs combined with results on compliance demonstrated cost-effectiveness in a bootstrap-based simulation analysis. CONCLUSIONS: A machine learning-based intelligent monitoring system increased daily compliance, reported excellent patient satisfaction similar to that reported in usual care, and did not incur in a substantial increase in costs, thus proving cost-effectiveness. This study supports the implementation of intelligent eHealth frameworks for the management of patients with CPAP-treated OSA and confirms the value of patients' empowerment in the management of chronic diseases.

OBJECTIVE: To assess the effectiveness and cost-effectiveness of primary care (PC) and sleep unit (SU) models for the management of subjects with suspected obstructive sleep apnoea (OSA). METHODS: Multicentre, open-label, two-arm, parallel-group, non-inferiority randomised controlled trial. A total of 302 subjects with suspected OSA and/or resistant hypertension were consecutively enrolled, 149 were treated at 11 PC units and 153 patients at a SU. The primary outcomes were a 6-month change in the Epworth Sleepiness Scale (ESS) score and Health Utilities Index (HUI). The non-inferiority margin for the ESS score was -2.0. RESULTS: A total of 80.2% and 70.6% of the PC and SU patients were diagnosed with OSA, respectively, and 59.3% and 60.4% of those were treated with CPAP in PC and SU units, respectively. The Apnoea-Hypopnoea Index was similar between the groups (PC vs SU (median (IQR); 23.1 (26.8) events/h vs 21.8 (35.2) events/h), and the baseline ESS score was higher in the PC than in the SU group (10.3 (6.6) vs 9 (7.2)). After 6 months, the ESS score of the PC group decreased from a mean of 10.1 to 7.6 (-2.49; 95% CI -3.3 to -1.69), and that of the SU group decreased from 8.85 to 5.73 (-3.11; 95% CI -3.94 to 2.28). The adjusted difference between groups for the mean change in the ESS score was -1.25 (one-sided 95% CI -1.88; p=0.025), supporting the non-inferiority of PC management. We did not observe differences in the HUI between groups. The cost analysis showed a median savings of 558.14/patient for the PC setting compared with the SU setting. CONCLUSIONS: Among patients with suspected OSA, the PC model did not result in a worse ESS score or HUI than the specialist model and generated savings in terms of management cost. Therefore, the PC model was more cost-efficient than the SU model. TRIAL REGISTRATION: Results; >>NCT02234765, Clinical Trials.gov.

BACKGROUND: Improved antiretroviral treatments and decrease in vertical transmission of HIV have led to a higher number of women living with HIV to consider childbearing. However, stigma and social rejection result in specific challenges that HIV positive women with procreation intentions have to face with. Our objective was to in depth analyse elements shaping their desire for procreation and specifically investigate the impact of HIV. METHODS: A qualitative study was conducted through open interviews with 20 women living with HIV between 18 and 45 years of age, from the Spanish AIDS Research Network Cohort (CoRIS). Interviews were audio-recorded and transcribed. A content analysis was performed. RESULTS: HIV diagnosis is a turning point in women's sexual and emotional life that is experienced traumatically. HIV diagnosis is usually associated with the fear of an immediate death and the idea of social isolation. At this moment, women temporarily reject future motherhood or having a sexual life. HIV status is only disclosed to the closed social circle and partner support is essential in HIV diagnosis assimilation process. Health professionals provide information on assisted reproductive technology and on how to minimize risk of partner HIV transmission. Most of barriers for procreation acknowledged by women are not related to HIV. However, women fear vertical transmission and experience other barriers derived from HIV infection. In this context, pregnancy makes women feel themselves as "normal women" despite HIV. Motherhood is considered an element of compensation that helps them to cope with HIV diagnosis. All these elements make health professionals key actors: they provide information and support after HIV diagnosis. CONCLUSIONS: Barriers and drivers for procreation are similar among HIV positive women and general population. However, stigma and discrimination linked with HIV weigh in HIV positive women decision of motherhood. In this context, it is necessary to provide these women with the necessary counselling, guidance and resources to take decisions about procreation properly informed.

BACKGROUND: Obstructive sleep apnea (OSA) is associated with a recurrent cardiovascular event (CVE) risk in patients with a first acute coronary syndrome (ACS). However, the pathological pathways by which OSA promotes this deleterious role are unknown. We aim to explore the proteomic profile associated with OSA that promote the recurrent CVE risk in severe OSA patients with ACS without previous cardiovascular diseases. METHODS: This post-hoc analysis from the ISAACC study (NCT01335087) included 86 patients admitted for ACS. Patients underwent respiratory polygraphy for the first 24-72 h to OSA diagnosis. We analyzed of 276 cardiovascular and inflammatory related proteins in baseline fasting plasma samples using proximity expression assay technology (Olink®, Sweden). Protein levels were compared between severe OSA patients with/without recurrent CVEs during follow-up. Random forest was conducted to select relevant proteins and generate a predictive model of recurrent CVE. RESULTS: We included 86 patients (median age: 61 years, median BMI: 29.4 kg/m2 and 86 % males) admitted for ACS with severe OSA (56 without recurrent CVE/30 with recurrent CVE). The plasma levels of 38 proteins were differentially expressed between groups. Additionally, 12 proteins had a significant association with respiratory polygraphy parameters. Three proteins discriminate with an AUC of 0.81 (95 % CI of 0.71-0.9) between severe OSA patients with and without recurrent CVE. These proteins were implicated in cell proliferation, communication and apoptosis, and regulation/response to the inflammatory and immune systems. CONCLUSION: In ACS patients with severe OSA, a proteomic profile was associated with recurrent CVEs. This proteomic profile was correlated with specific OSA parameters from respiratory polygraphy. Proteomic profiling may provide an new direction for patient risk stratification and clinical management.

The study compares the toxicity of 53 selected medicinal plants commonly used in the Philippines to treat various diseases. It uses as a benchmark Vitex negundo L., which was approved by the Philippine Food and Drug Administration as an herbal drug for cough and asthma after passing clinical trials for safety and efficacy. The methods were chosen for their simplicity and accessibility even for resource-limited laboratories. Extracts (95 % ethanol) of the medicinal parts of the plants were (1) chemically profiled using qualitative phytochemical tests that detect the presence of key classes of bioactive compounds; and (2) evaluated for toxicity using the brine shrimp (Artemia sp.) lethality assay (BSLA). General phytochemical screening revealed the presence of tannins in 50 plant extracts, alkaloids in 43, glycosides in 33, flavonoids in 31, steroids in 21, triterpenoids in 20, anthraquinones in 10, and saponins in 8. Extracts from eight plants had LC50 values lower than the potassium dichromate control (approximately 12 µg/mL) and were considered highly toxic; extracts from 21 plants had LC50 values between 12 µg/mL and 100 µg/mL and were considered moderately toxic; extracts from 19 plant extracts, including Vitex negundo and some common vegetables, had LC50 values between 100 µg/mL and 500 µg/mL, and were considered mildly toxic and likely to have reasonable safety margins; five plant extracts, including common vegetables, had LC50 values above 500 µg/mL and were considered essentially nontoxic. No apparent correlation could be found between toxicity and chemical diversity or a specific class of phytochemicals present. Our findings may serve as a guide for herbal drug and nutraceutical development, especially in prioritizing plants for more detailed safety studies.
RESUMO
Rationale: Obstructive sleep apnea (OSA) is prevalent in patients with acute coronary syndrome (ACS) and is a cause of secondary hypertension. Objectives: To explore the long-term effects of OSA and continuous positive airway pressure (CPAP) treatment on blood pressure (BP) in patients with ACS. Methods: Post hoc analysis of the ISAACC study (Continuous Positive Airway Pressure in Patients with Acute Coronary Syndrome and Obstructive Sleep Apnea; NCT01335087) included 1,803 patients admitted for ACS. Patients with OSA (apnea-hypopnea index [AHI], ⩾15 events/h) were randomly assigned to receive either CPAP or usual care and were seen in follow-up for 1-5 years. Office BP was determined at each visit. Results: We included 596 patients without OSA, 978 patients in the usual care or poor CPAP adherence group, and 229 patients in the good CPAP adherence group. At baseline, 52% of the patients were diagnosed with hypertension. Median (25th to 75th percentile) age and body mass index were 59 (52.0 to 67.0) years and 28.2 (25.6 to 31.2) kg/m2, respectively. After a median (25th to 75th percentile) follow-up of 41.2 (18.3 to 59.6) months, BP changes were similar in the OSA and non-OSA groups. However, we observed an increase in BP in the third tertile of the AHI (AHI, >40 events/h), with a maximum difference in mean BP of +3.3 mm Hg at 30 months. Patients with OSA with good CPAP adherence (⩾4 h/night) reduced mean BP after 18 months compared with patients with usual care/poor CPAP adherence, with a maximum mean difference (95% confidence interval) of -4.7 (-6.7 to -2.7) mm Hg. In patients with severe OSA, we observed a maximum mean difference of -7.1 (-10.3 to -3.8) mm Hg. Conclusions: In patients with ACS, severe OSA is associated with a long-term increase in BP, which is reduced by good CPAP adherence.

Introduction: Obstructive sleep apnea (OSA) severity is based on the apnea-hypopnea index (AHI). The AHI is a simplistic measure that is inadequate for capturing disease severity and its consequences in cardiovascular diseases (CVDs). Deleterious effects of OSA have been suggested to influence the prognosis of specific endotypes of patients with acute coronary syndrome (ACS). We aim to identify respiratory polygraphy (RP) patterns that contribute to identifying the risk of recurrent cardiovascular events in patients with ACS. Methods: Post hoc analysis of the ISAACC study, including 723 patients admitted for a first ACS (NCT01335087) in which RP was performed. To identify specific RP patterns, a principal component analysis (PCA) was performed using six RP parameters: AHI, oxygen desaturation index, mean and minimum oxygen saturation (SaO2), average duration of events and percentage of time with SaO2 < 90%. An independent HypnoLaus population-based cohort was used to validate the RP components. Results: From the ISAACC study, PCA showed that two RP components accounted for 70% of the variance in the RP data. These components were validated in the HypnoLaus cohort, with two similar RP components that explained 71.3% of the variance in the RP data. The first component (component 1) was mainly characterized by low mean SaO2 and obstructive respiratory events with severe desaturation, and the second component (component 2) was characterized by high mean SaO2 and long-duration obstructive respiratory events without severe desaturation. In the ISAACC cohort, component 2 was associated with an increased risk of recurrent cardiovascular events in the third tertile with an adjusted hazard ratio (95% CI) of 2.44 (1.07 to 5.56; p-value = 0.03) compared to first tertile. For component 1, no significant association was found for the risk of recurrent cardiovascular events. Conclusion: A RP component, mainly characterized by intermittent hypoxemia, is associated with a high risk of recurrent cardiovascular events in patients without previous CVD who have suffered a first ACS.
RESUMO
To fight the virus SARS-CoV-2 spread to Europe from China and to give support to the collapsed public health system, the Spanish Health Authorities developed a field hospital located in the facilities of Madrid exhibition centre (IFEMA) to admit and treat patients diagnosed with SARS-CoV-2 infectious disease (COVID-19). The Department of Laboratory Medicine of La Paz University Hospital in Madrid (LMD-HULP) was designated to provide laboratory services. Due to the emergency, the IFEMA field hospital had to be prepared for patient admission in less than 1 week and the laboratory professionals had to collaborate in a multidisciplinary group to assure that resources were available to start on time. The LMD-HULP participated together with the managers in the design of the tests portfolio and the integration of the healthcare information systems (IS) (hospital IS, laboratory IS and POCT management system). Laboratorians developed a strategy to quickly train clinicians and nurses on test requests, sample collection procedures and management/handling of the POCT blood gas analyser both by written materials and training videos. The IFEMA´s preanalytical unit managed 3782 requests, and more than 11,000 samples from March 27th to April 30th. Furthermore, 1151 samples were measured by blood gas analysers. In conclusion, laboratory professionals must be resilient and have to respond timely in emergencies as this pandemic. The lab's personnel selection, design and monitoring indicators to maintain and further improve the quality and value of laboratory services is crucial to support medical decision making and provide better patient care.

BACKGROUND: Despite the improvement in the prognosis of acute coronary syndrome (ACS), substantial morbidity and mortality remain. We aimed to evaluate the effect of obstructive sleep apnoea (OSA) and its treatment with continuous positive airway pressure (CPAP) on the clinical evolution of patients with ACS. METHODS: We designed a multicentre, open-label, parallel-group, randomised controlled trial of patients with ACS at 15 hospitals in Spain. Eligible non-sleepy patients were men and women aged 18 years and older, admitted to hospital for documented symptoms of ACS. All patients underwent respiratory polygraphy during the first 24-72 h after admission. OSA patients were randomly assigned (1:1) to CPAP treatment plus usual care (CPAP group) or usual care alone (UC group) by a computerised system available 24 h a day. A group of patients with ACS but without OSA was also included as a reference group. Because of the nature of the intervention, the trial intervention could not be masked to either investigators or patients. Patients were monitored and followed for a minimum of 1 year. Patients were examined at the time of inclusion; after 1 month, 3 months, 6 months, 12 months, 18 months, 24 months, 30 months, and 36 months; and every 12 months thereafter, if applicable, during the follow-up period. The primary endpoint was the prevalence of a composite of cardiovascular events (cardiovascular death or non-fatal events [Acute myocardial infarction, non-fatal stroke, hospital admission for heart failure, and new hospitalisations for unstable angina or transient ischaemic attack]) in patients followed up for a minimum of 1 year. The primary analysis was done according to the intention-to-treat principle. This study is registered with Clinicaltrials.gov, NCT01335087 and is now closed. FINDINGS: Between April 25, 2011, and Feb 2, 2018, a total of 2834 patients with ACS had respiratory polygraphy, of whom 2551 (90·01%) were recruited. 1264 (49·55%) patients had OSA and were randomly assigned to the CPAP group (n=633) or the UC group (n=631). 1287 (50·45%) patients did not have OSA, of whom 603 (46·85%) were randomly assigned to the reference group. Patients were followed up for a median of 3·35 years (IQR 1·50-5·31). The prevalence of cardiovascular events was similar in the CPAP and UC groups (98 events [16%] vs 108 events [17%]; hazard ratio [HR] 0·89 [95% CI 0·68-1·17]; p=0·40) during follow-up. Mean time of adherence to CPAP treatment was 2·78 h/night (SD 2·73). The prevalence of cardiovascular events was similar between patients in the reference group (90 [15%] events) and those in the UC group (102 (17%) events) during follow-up (1·01 [0·76-1·35]; p=0·93). The prevalence of cardiovascular events seem not to be related to CPAP compliance or OSA severity. 464 (74%) of 629 patients in the CPAP group had 1538 serious adverse events and 406 (65%) of 626 patients in the UC group had 1764 serious adverse events. INTERPRETATION: Among non-sleepy patients with ACS, the presence of OSA was not associated with an increased prevalence of cardiovascular events and treatment with CPAP did not significantly reduce this prevalence.

Evaluation of microRNAs (miRNAs) could allow characterization of the obstructive sleep apnea (OSA) and help diagnose it more accurately. We aimed to examine circulating miRNA profiles to establish the differences between non-OSA and OSA patients. Additionally, we aimed to analyse the effect of continuous positive airway pressure (CPAP) treatment on the miRNA profile. This observational, longitudinal study included 230 subjects referred to the Sleep Unit due to suspected OSA. Expression profiling of 188 miRNAs in plasma was performed in 27 subjects by TaqMan-Low-Density-Array. OSA-related miRNAs were selected for validation by RT-qPCR in 203 patients. Prediction models were built to discriminate between non-OSA and OSA: 1) NoSAS-score, 2) differentially expressed miRNAs, and 3) combination of NoSAS-score plus miRNAs. The differentially expressed miRNAs were measured after 6 months of follow-up. From the 14 miRNAs selected for validation, 6 were confirmed to be differentially expressed. The areas under the curve were 0.73 for the NoSAS-score, 0.81 for the miRNAs and 0.86 for the combination. After 6 months of CPAP treatment, miRNA levels in the OSA group seem to approximate to non-OSA levels. A cluster of miRNAs was identified to differentiate between non-OSA and OSA patients. CPAP treatment was associated with changes in the circulating miRNA profile.

OBJECTIVES: Obstructive sleep apnea (OSA) is among the least studied risk factors for erectile dysfunction (ED). We aimed to determine ED prevalence in newly-diagnosed OSA patients, describe their main characteristics and assess continuous positive airway pressure (CPAP) effects on ED. METHODS: Cross-sectional study assessing ED prevalence in OSA patients and open-label, parallel, prospective randomized controlled trial evaluating 3-month CPAP treatment effects on sexual function, satisfaction, and psychological, hormonal and biochemical profiles. Male patients newly diagnosed with moderate/severe OSA (apnea-hypopnea index >20 events·h-1), aged 18-70 years, attending the sleep unit of a Spanish hospital during 2013-2016 were considered. A total of 150 patients were recruited (75 randomized ED patients). ED was defined as scores <25 on International Index Erectile Function 15 test. Wilcoxon's matched-pairs signed-ranks and rank-sum tests were used. RESULTS: ED prevalence was 51%. Patients with ED were older (p<0.001), had greater waist-to-hip ratios (p<0.001), were more frequently undergoing pharmacological treatment (p<0.001) and had higher glucose levels (p = 0.024) than non-ED patients. Although significant increases in erectile function (mean(SD) change: +4.6(7.9); p = 0.002), overall satisfaction (+1(2.2); p = 0.035), and sexual satisfaction (+2.1(4.3); p = 0.003) were found after CPAP treatment, only differences in sexual satisfaction (p = 0.027) and erectile function (p = 0.060) were found between study arms. CPAP treatment did not impact psychological, hormonal or biochemical profiles. CONCLUSIONS: This study confirmed the relationship between OSA and ED, suggesting the potential usefulness of ED screening in OSA patients, but could not determine conclusively whether CPAP is an effective stand-alone ED treatment, regardless of positive results on sexual satisfaction.

INTRODUCTION AND OBJECTIVE: The valuation of anthropometric and nutritional status of the university population is important to detect risk groups and so make nutritional recommendations. The aim of the study was to analyze the body composition and the fat component in a group of university students and to evaluate their basal metabolism to see if there was a correlation with the body composition. The study was carried out through different methods, to determine if the results obtained are comparable. SUBJECTS AND METHOD: The sample were 16 students (4 males and 12 females) from the University of Valencia, 20-33 years old. To all of them was carried out the study of body composition, and to 6 of them was carried out also a metabolic study. RESULTS: It was found that 75% of the studied subjects are normal weight, 12,5% are underweight and 12,5% are overweight. The percentage of subjects with body fat higher than the normal values are: 68,75% according to BFMNU, 25% through ISAK method and 7,69% with BIA. CONCLUSIONS: Our study reflected that the data obtained through the different methods are not directly comparable because they are based on different principles and assumptions. It was noticed the importance of considering not only fat mass, but the whole body composition to have a complete picture of the subject. Furthermore, we it was found that Indirect Calorimetry and the predictive equations are not able to estimate it correctly. In contrast BFMNU method is the one that gives more information and allows to thoroughly investigate the metabolism.
Introducción y objetivo: La valoración del estado antropométrico y nutricional de la población universitaria es importante para detectar grupos de riesgo y realizar recomendaciones nutricionales. El objetivo fue analizar la composición corporal y el porcentaje de grasa en un grupo de estudiantes universitarios y evaluar su metabolismo basal para ver si había una correlación con la composición corporal. El estudio se llevó a cabo a través de diferentes métodos, para determinar si los resultados obtenidos son comparables. Sujetos y método: La muestra fueron 16 alumnos (4 hombres y 12 mujeres) de la Universidad de Valencia, 20- 33 años de edad. A todos se hizo el estudio de la composición corporal y a 6 de ellos se hizo también un estudio metabólico. Resultados: Se encontró que el 75% de los sujetos estudiados tienen un peso normal, el 12,5% tienen bajo peso y 12,5% tiene sobrepeso. El porcentaje de sujetos con grasa corporal superior a los valores normales son: 68,75% según BFMNU, el 25% a través del método ISAK y 7,69% según BIA. Conclusiones: Nuestro estudio mostró que los datos obtenidos a través de los diferentes métodos no son directamente comparables, ya que se basan en diferentes principios y supuestos. También se ha observado la importancia de considerar no sólo la masa grasa, si no toda la composición corporal para tener una visión completa del sujeto. Además, se ha podido notar que la calorimetría indirecta y las ecuaciones de predicción del metabolismo basal no son capaces de estimarlo correctamente. En cambio el método BFMNU es el que da más información y permite investigar a fondo el metabolismo.

Antecedentes: Las candidiasis son infecciones oportunistas producidas por levaduras, cuyo agente etiológico implicado más frecuente C.albicans generando problemas a varios niveles. Caso clínico: Mujer de 39 años diagnosticada de Candidiasis intestinal crónica cursando con sintomatología amplia y variada. Tras la valoración se procede a complementar el tratamiento con una alimentación centrada en la eliminación de azúcares simples, levaduras y productos fermentados. Además, se incluyen ácido caprílico, aceite de orégano y L.acidophylus. Conclusiones: Existe un aumento de la actividad inmunológica acompañada de la mejora sintomatológica (AU)
Background: Candidiasis are opportunistic yeast infections, the most common etiologic agent involved C.albicans creating problems at various levels. Case report: 39-year old woman diagnosed by chronic intestinal Candidiasis studying with wide and varied symptoms. After evaluation proceeds to complement treatment with diet consisted in removal of simple sugars, yeast and fermented products. Furthermore, caprylic acid and oregano oil L.acidophylus include.

Fundamentos: Los cambios realizados en los últimos años en los países occidentalizados han contribuido al incremento de los usuarios en los comedores colectivos, en empresas y colegios. En este trabajo se valoran los menús escolares atendiendo a las normas descritas a nivel nacional y autonómico para la prevención de enfermedades y mejora del estado de salud. Métodos: Se analizan tres menús consecutivos de una empresa de restauración colectiva de 20 días cada uno, divididos en bloques de 5 días simulando la semana de ingesta en el comedor escolar, para usuarios entre 9 y 13 años. Resultados: Los menús analizados suministran un aporte energético medio de 32,6% de la energía diaria, dentro del rango recomendado. Sin embargo, destaca un elevado aporte proteico (20,1%) centrado en el consumo de lácteos, carnes magras, pescados blancos y huevos. Los aportes suministrados de vitamina C, vitamina A y hierro permiten satisfacer los requerimientos medios estimados. Sin embargo, para el calcio y vitamina E no debiéndose complementar con los aportes domésticos. Conclusiones: Los menús escolares analizados ofrecen un aporte energético de acuerdo a las recomendaciones, aunque destaca una contribución elevada a partir de la ingesta proteica. La intervención de dietistas-nutricionistas en el diseño y planificación de los menús suministrados permite una mejor configuración nutricional, la evaluación continuada y mejora de la oferta, además de su potencial contribución al asesoramiento individual y otras actividades de información-educación nutricional (AU)
Background: The changes that are taking place in recent years in western countries have shown an increase in the number of users in the canteens, both in companies and in schools. In this paper school menus are assessed according to the standards established at national and regional level for disease prevention and health improvement. Methods: We analyzed three consecutive menus offered by a catering company of 20 days each, divided into blocks of five days a week simulating intake in the cafeteria for users between 9 and 13 years. Results: The analyzed menus provide an average energy intake of 32.6 % of the daily energy, within the recommended range. Result highlight a large contribution from the protein intake (20.1%) provided by the consumption of dairy, lean meats, fish and eggs. The amounts provided of vitamin C, vitamin A and iron satisfy the estimated average requirements for these nutrients However, those for calcium and vitamin E do not meet the daily requirement and must be complemented with domestic contributions. Conclusions: The school menus analyzed provide an energy intake according to recommendations, but a high contribution from protein intake . The involvement of nutritionists - dietitians in the design and planning of school menus contributes to a better nutrition profile of the offer and enables continuous assessment and improvement of the offer, in addition to its potential contribution to individual counseling and other nutritional information-education activities (AU)
