    El síndrome de Kleine-Levin es un trastorno raro, caracterizado por episodios recurrentes de hipersomnia, alteraciones del apetito, disfunción cognitiva y conducta desinhibida; se estima que afecta entre una y cinco personas por millón de habitantes y es cuatro veces más frecuente en el sexo masculino. Se presenta el caso de un paciente masculino, de 18 años de edad, evaluado en la consulta de trastornos del sueño, en Villa Clara, por haber sufrido en cinco ocasiones de hipersomnia, de siete a diez días de duración, separados por tres o cuatro meses. Durante estos periodos se mostró irritable, apático y con anorexia. Fuera del cuadro clínico de hipersomnia el comportamiento es normal. El paciente cumple los criterios de la 3ra Clasificación Internacional de los Trastornos del sueño para el diagnóstico del síndrome de Kleine-Levin. Se decidió la presentación del caso por lo infrecuente de este padecimiento, cuyo diagnóstico se hace a los 15 meses de su comienzo y porque no existen referencias bibliográficas previas en Cuba

    Introduction: advances in the knowledge of Epigenetics and its relationship with morbidity in adulthood emphasize more strongly the impact that a woman's diet has during pregnancy. Objective: to know the consumption of food and the dietary and toxic habits of pregnant women. Method: a descriptive and cross-sectional study was conducted in which a standardized interview was applied through the use of a semi-structured questionnaire to 100 pregnant women who attended the Genetics Services in the period between June and November 2016 in the Province of Villa Clara. Results: a large number of pregnant women consume fresh meat, milk, fish and fruits and in smaller quantities, vegetables; Pork meat is the most commonly consumed and many have no habit eat the pork liver ; A large number of woman did not take folic acid before pregnancy due to ignorance. Some pregnant women practice smoking and drink alcohol because they are unaware of the effects on pregnancy and its product. Conclusions: the majority of the pregnant women interviewed, report that they prefer to consume milk, pork and chicken, just over half reported eating liver, the highest percentage do not consume folic acid before pregnancy, and persist pregnant women who drink alcoholic beverages, coffee and cigarettes and expose your health and that of the future baby to its harmful effects.Introducción: los avances en los conocimientos de la Epigenética y su relación con la morbilidad en la edad adulta enfatizan con más fuerza en el impacto que tiene la alimentación de la mujer durante el embarazo. Objetivo: conocer el consumo de alimentos y los hábitos dietéticos y tóxicos de las gestantes. Método: se realizó un estudio descriptivo y transversal en el que se aplicó una entrevista estandarizada mediante el uso de un cuestionario semi-estructurado a 100 gestantes que asistieron a los Servicios de Genética en el período comprendido entre junio y noviembre de 2016 en la Provincia de Villa Clara. Resultados: un gran número de embarazadas consume carne, leche, pescado y frutas frescas y, en menor cantidad, vegetales; la carne de cerdo es la que se consumen con mayor frecuencia y muchas no tienen hábito de consumir hígado; un gran número no tomó el ácido fólico preconcepcional por desconocimiento. Algunas practican el hábito de fumar e ingieren bebidas alcohólicas porque desconocen los efectos sobre el embarazo y su producto. Conclusiones: de las gestantes entrevistadas la mayoría refieren consumir preferentemente leche, carne de cerdo y pollo, poco más de la mitad refirió ingerir hígado, el mayor por ciento no consume ácido fólico preconcepcional y persisten embarazadas que ingieren bebidas alcohólicas, café y cigarros y exponen su salud y la del futuro bebé a sus efectos nocivos

    Introducción: En México, el cáncer de mama es la primera causa de muerte en mujeres. En el desarrollo del cáncer de mama, participan las proteínas de estrés térmico (Hsp); En particular la Hsp27, Hsp70 y Hsp90 que aseguran la sobrevida de las células cancerosas, y en algunos casos de cáncer de mama, se forman complejos de Hsp70 y Hsp90 con p53. P53 interviene en la regulación del ciclo celular y en la apoptosis, donde más del 50% de los tumores humanos contiene mutaciones de este gen, permitiendo que las células anormales proliferen dando como resultado cáncer. Objetivo: Analizar en muestras de cáncer de mama, la expresión y asociación de las proteínas Hsp70, Hsp90 y P53. Material y métodos: Se obtuvieron 15 muestras de tejido mamario mediante biopsia y/o cirugía (11 con cáncer de mama, 3 alteraciones de la mama y 1 control negativo), donde se analizó la expresión y asociación de las proteínas Hsp70, 90 y p53 mediante inmunoprecipitación, Western Blot-ECL. Resultados: Las proteínas Hsp70, Hsp90 y p53 se expresaron en todas las muestras de tejido mamario canceroso, siendo mayor la expresión de Hsp70 seguido de p53 y en menor cantidad la Hsp90, y al analizar su asociación, se encontró a la Hsp70 con Hsp90 y p53, en 6 muestras. Así mismo, en alteraciones de la glándula mamaria, se encontró una mayor expresión de Hsp70. Conclusiones: Las proteínas Hsp70, Hsp90 y p53 se sobreexpresan en tejido canceroso, y se asocian entre ellas en 66.6% de las muestras analizadas

    The primary aim of our study was to investigate the association between intubation timing and hospital mortality in critically ill patients with COVID-19-associated respiratory failure. We also analysed both the impact of such timing throughout the first four pandemic waves and the influence of prior non-invasive respiratory support on outcomes. This is a secondary analysis of a multicentre, observational and prospective cohort study that included all consecutive patients undergoing invasive mechanical ventilation due to COVID-19 from across 58 Spanish intensive care units (ICU) participating in the CIBERESUCICOVID project. The study period was between 29 February 2020 and 31 August 2021. Early intubation was defined as that occurring within the first 24 h of intensive care unit (ICU) admission. Propensity score (PS) matching was used to achieve balance across baseline variables between the early intubation cohort and those patients who were intubated after the first 24 h of ICU admission. Differences in outcomes between early and delayed intubation were also assessed. We performed sensitivity analyses to consider a different timepoint (48 h from ICU admission) for early and delayed intubation. Of the 2725 patients who received invasive mechanical ventilation, a total of 614 matched patients were included in the analysis (307 for each group). In the unmatched population, there were no differences in mortality between the early and delayed groups. After PS matching, patients with delayed intubation presented higher hospital mortality (27.3% versus 37.1%, p =0.01), ICU mortality (25.7% versus 36.1%, p=0.007) and 90-day mortality (30.9% versus 40.2%, p=0.02) when compared to the early intubation group. Very similar findings were observed when we used a 48-hour timepoint for early or delayed intubation. The use of early intubation decreased after the first wave of the pandemic (72%, 49%, 46% and 45% in the first, second, third and fourth wave, respectively; first versus second, third and fourth waves p<0.001). In both the main and sensitivity analyses, hospital mortality was lower in patients receiving high-flow nasal cannula (n=294) who were intubated earlier. The subgroup of patients undergoing NIV (n=214) before intubation showed higher mortality when delayed intubation was set as that occurring after 48 h from ICU admission, but not when after 24 h. In patients with COVID-19 requiring invasive mechanical ventilation, delayed intubation was associated with a higher risk of hospital mortality. The use of early intubation significantly decreased throughout the course of the pandemic. Benefits of such an approach occurred more notably in patients who had received high-flow nasal cannul

    Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

    Population-based multicase-control study in common tumors in Spain (MCC-Spain): rationale and study design

    Introduction: We present the protocol of a large population-based case-control study of 5 common tumors in Spain (MCC-Spain) that evaluates environmental exposures and genetic factors. Methods: Between 2008-2013, 10,183 persons aged 20-85 years were enrolled in 23 hospitals and primary care centres in 12 Spanish provinces including 1,115 cases of a new diagnosis of prostate cancer, 1,750 of breast cancer, 2,171 of colorectal cancer, 492 of gastro-oesophageal cancer, 554 cases of chronic lymphocytic leukaemia (CLL) and 4,101 population-based controls matched by frequency to cases by age, sex and region of residence. Participation rates ranged from 57% (stomach cancer) to 87% (CLL cases) and from 30% to 77% in controls. Participants completed a face-to-face computerized interview on sociodemographic factors, environmental exposures, occupation, medication, lifestyle, and personal and family medical history. In addition, participants completed a self-administered food-frequency questionnaire and telephone interviews. Blood samples were collected from 76% of participants while saliva samples were collected in CLL cases and participants refusing blood extractions. Clinical information was recorded for cases and paraffin blocks and/or fresh tumor samples are available in most collaborating hospitals. Genotyping was done through an exome array enriched with genetic markers in specific pathways. Multiple analyses are planned to assess the association of environmental, personal and genetic risk factors for each tumor and to identify pleiotropic effects. Discussion: This study, conducted within the Spanish Consortium for Biomedical Research in Epidemiology & Public Health (CIBERESP), is a unique initiative to evaluate etiological factors for common cancers and will promote cancer research and prevention in Spain.The study was partially funded by the “Accion Transversal del Cancer”, approved on the Spanish Ministry Council on the 11th October 2007, by the Instituto de Salud Carlos III-FEDER (PI08/1770, PI08/0533, PI08/1359, PS09/00773, PS09/01286, PS09/01903, PS09/02078, PS09/01662, PI11/01403, PI11/01889, PI11/00226, PI11/01810, PI11/02213, PI12/00488, PI12/00265, PI12/01270, PI12/00715, PI12/00150), by the Fundación Marqués de Valdecilla (API 10/09), by the ICGC International Cancer Genome Consortium CLL, by the Junta de Castilla y León (LE22A10-2), by the Consejería de Salud of the Junta de Andalucía (PI-0571), by the Conselleria de Sanitat of the Generalitat Valenciana (AP 061/10), by the Recercaixa (2010ACUP 00310), by the Regional Government of the Basque Country by European Commission grants FOOD-CT- 2006-036224-HIWATE, by the Spanish Association Against Cancer (AECC) Scientific Foundation, by the The Catalan Government DURSI grant 2009SGR1489

    Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation
