Phenotype and Clinical Outcomes in Desmin-Related Arrhythmogenic Cardiomyopathy.

BACKGROUND: Desmin (DES) pathogenic variants cause a small proportion of arrhythmogenic cardiomyopathy (ACM). Outcomes data on DES-related ACM are scarce. OBJECTIVES: This study sought to provide information on the clinical phenotype and outcomes of patients with ACM caused by pathogenic variants of the DES gene in a multicenter cohort. METHODS: We collected phenotypic and outcomes data from 16 families with DES-related ACM from 10 European centers. We assessed in vitro DES aggregates. Major cardiac events were compared to historical controls with lamin A/C truncating variant (LMNA-tv) and filament C truncating variant (FLNC-tv) ACM. RESULTS: Of 82 patients (54% males, median age: 36 years), 11 experienced sudden cardiac death (SCD) (n = 7) or heart failure death (HFd)/heart transplantation (HTx) (n = 4) before clinical evaluation. Among 68 survivors, 59 (86%) presented signs of cardiomyopathy, with left ventricular (LV) dominant (50%) or biventricular (34%) disease. Mean LV ejection fraction was 51% ± 13%; 36 of 53 had late gadolinium enhancement (ring-like pattern in 49%). During a median of 6.73 years (Q1-Q3: 3.55-9.52 years), the composite endpoint (sustained ventricular tachycardia, aborted SCD, implantable cardioverter-defibrillator therapy, SCD, HFd, and HTx) was achieved in 15 additional patients with HFd/HTx (n = 5) and SCD/aborted SCD/implantable cardioverter-defibrillator therapy/sustained ventricular tachycardia (n = 10). Male sex (P = 0.004), nonsustained ventricular tachycardia (P = 0.017) and LV ejection fraction ≤50% (P = 0.012) were associated with the composite endpoint. Males with DES variants had similar outcomes to historical FLNC-tv and LMNA-tv controls. However, females showed better outcomes than those with LMNA-tv. In vitro experiments showed the characteristic finding of DES aggregates in 7 of 12 variants. CONCLUSIONS: DES ACM is associated with poor outcomes which can be predicted with potentially successful treatments, underscoring the importance of familial evaluation and genetic studies to identify at risk individuals.

Single-operator cholangioscopy unveiling a pinehole post-cholecystectomy biliary strictures.

77-year-old female with history of cholecystectomy was admitted at emergency department with fever and myalgia, without other complaints. Physical examination revealed fever, and laboratory tests indicated cholestasis (total bilirubin: 1.5xULN, glutamyltransferase: 20xULN, alkaline phosphatase: 5xULN). Computed Tomography revealed common bile duct (CBD) dilation (9mm), with suspected choledocholithiasis. Given the diagnosis of acute cholangitis, antibiotics were started and ERCP was performed. ERCP revealed a short CBD stenosis (< 2mm length), close to surgical clip, with upstream dilation of the CBD; an 8mm stone in the distal CBD was observed and successfully removed. As guidewire advancement failed after multiple attempts, a SpyGlass DS cholangioscopy was performed showing a fibrotic pinehole stenosis. Guidewire was passed through the stenosis under direct visualization, and an 80-mmx10mm fully covered metal stent deployed.

Pregnancy in women with dilated cardiomyopathy genetic variants.

INTRODUCTION AND OBJECTIVES: Limited information is available on the safety of pregnancy in patients with genetic dilated cardiomyopathy (DCM) and in carriers of DCM-causing genetic variants without the DCM phenotype. We assessed cardiac, obstetric, and fetal or neonatal outcomes in this group of patients. METHODS: We studied 48 women carrying pathogenic or likely pathogenic DCM-associated variants (30 with DCM and 18 without DCM) who had 83 pregnancies. Adverse cardiac events were defined as heart failure (HF), sustained ventricular tachycardia, ventricular assist device implantation, heart transplant, and/or maternal cardiac death during pregnancy, or labor and delivery, and up to the sixth postpartum month. RESULTS: A total of 15 patients, all with DCM (31% of the total cohort and 50% of women with DCM) experienced adverse cardiac events. Obstetric and fetal or neonatal complications were observed in 14% of pregnancies (10 in DCM patients and 2 in genetic carriers). We analyzed the 30 women who had been evaluated before their first pregnancy (12 with overt DCM and 18 without the phenotype). Five of the 12 (42%) women with DCM had adverse cardiac events despite showing NYHA class I or II before pregnancy. Most of these women had a history of cardiac events before pregnancy (80%). Among the 18 women without phenotype, 3 (17%) developed DCM toward the end of pregnancy. CONCLUSIONS: Cardiac complications during pregnancy and postpartum were common in patients with genetic DCM and were primarily related to HF. Despite apparently good tolerance of pregnancy in unaffected genetic carriers, pregnancy may act as a trigger for DCM onset in a subset of these women.

Ketamine in Chronic Pain: A Review.

Ketamine has been used in the treatment of several pain syndromes, particularly those with a relevant neuropathic component. Sub-anesthetic doses of ketamine produce a potent analgesic effect, due to its inhibition of N-methyl-D-aspartate receptors and enhancement of descending inhibitory pathways. Its short-term analgesic effect is well-documented perioperatively, with an associated reduction in postoperative chronic pain and opioid consumption. Despite some evidence regarding its long-term benefits, the number of clinical studies is still limited. In addition to its analgesic effects, ketamine also possesses an anti-depressive action, which might be useful in the treatment of chronic pain patients. Several side effects have been described, the psychomimetic ones being the most relevant due to their impact on treatment adhesion. At present, co-administration of ketamine and benzodiazepines or α2-agonists facilitates its clinical application. Despite current evidence and increasing use, further investigation is still needed regarding its long-term safety profile and clearer risk-benefit analysis.

Medical cannabis use in oncology and associated outcomes: A scoping review.

BACKGROUND: Natural and synthetic cannabinoids are being used worldwide to treat various symptoms in cancer patients. This study aims to map the therapeutic benefits and adverse effects associated with the use of cannabis-based drugs in these outcomes. METHODS: Following Joanna Briggs Institute guidelines a scoping review was conducted. The study protocol was available in the Open Science Framework public repository. An extensive search strategy involving databases like Cochrane Library, Embase, CINAHL, Medline/PubMed, Lilacs, Google Scholar, and Open Gray for gray literature analysis was executed by a skilled librarian. The inclusion criteria were primary studies (observational and randomized) that evaluated the efficacy and safety of cannabinoids in cancer patients. The review encompassed studies of diverse designs, publication years, and types, as long as they addressed cannabinoids' impact in oncology. RESULTS: Twenty-nine (82.86%) out of total of 35 were randomized and 6 (14.14%) were non-randomized. About 57.1% of studies utilized registered products as interventions, with THC being the most natural cannabinoid cited in variable doses and administration routes. Moreover, 62.85% of studies specified the cancer types (breast, lung, sarcomas, hematological and reproductive system), while only one study detailed cancer staging. The evaluated outcomes encompassed nausea and vomiting (77.14%), appetite (11.43%), pain (8.57%), and tumor regression (2.86%) across different proportions of studies. CONCLUSION: Cannabinoids show promise in managing pain, emesis, and anorexia/cachexia linked to cancer progression. New randomized clinical trials with a larger number of participants and observational studies on long-term safety are crucial to affirm their medicinal utility for cancer patients unresponsive to conventional drugs.

Cost-Effectiveness of Inpatient Continuous Glucose Monitoring.

Introduction Our department conducted a retrospective cohort study to compare the efficacy of continuous glucose monitoring devices versus capillary blood glucose in the glycemic control of inpatient type 2 diabetes on intensive insulin therapy in a Portuguese hospital. The use of continuous glucose monitoring devices was associated with improved glycemic control, including an increased number of glucose readings within target range and reduced hyperglycemic events, being safe concerning hypoglycemias. This is the cost-effectiveness analysis associated with these results. Aim The primary objective was to compare the cost-effectiveness of achieving glycemic control, defined as the number of patients within glycemic goals, between groups. Secondary endpoints included cost-effectiveness analyses of each time in range goal, and each percentual increment in time in range. Methods We defined each glycemic goal as: "readings within range (70-180 mg/dL) >70%", "readings below range (below 70 mg/dL) <4%", "severe hypoglycemia (below 54 mg/dL) <1%", "readings above range (above 180 mg/dL) <25%", "very high glycemic readings (above 250 mg/dL) <5%". Results Continuous glucose monitoring showed lower median cost per effect for the primary outcome (€11.1 vs. €34.9/patient), with lower cost for readings in range (€7.8 vs. €11.6/patient) and for both readings above range goals ("above 180mg/dL": €7.4 vs. €9.9/patient, and "above 250mg/dL": €6.9 vs. €17.4/patient). Conclusions There are no published data regarding the cost-effectiveness of continuous glucose monitoring devices in inpatient settings. Our results show that continuous glucose monitoring devices were associated with an improved glycemic control, at a lower cost, and endorse the feasibility of incorporating these devices into hospital settings, presenting a favorable cost-effective option compared to capillary blood glucose.

Electrophysiological Characterization of Subclinical and Overt Hypertrophic Cardiomyopathy by Magnetic Resonance Imaging-Guided Electrocardiography.

BACKGROUND: Ventricular arrhythmia in hypertrophic cardiomyopathy (HCM) relates to adverse structural change and genetic status. Cardiovascular magnetic resonance (CMR)-guided electrocardiographic imaging (ECGI) noninvasively maps cardiac structural and electrophysiological (EP) properties. OBJECTIVES: The purpose of this study was to establish whether in subclinical HCM (genotype [G]+ left ventricular hypertrophy [LVH]-), ECGI detects early EP abnormality, and in overt HCM, whether the EP substrate relates to genetic status (G+/G-LVH+) and structural phenotype. METHODS: This was a prospective 211-participant CMR-ECGI multicenter study of 70 G+LVH-, 104 LVH+ (51 G+/53 G-), and 37 healthy volunteers (HVs). Local activation time (AT), corrected repolarization time, corrected activation-recovery interval, spatial gradients (GAT/GRTc), and signal fractionation were derived from 1,000 epicardial sites per participant. Maximal wall thickness and scar burden were derived from CMR. A support vector machine was built to discriminate G+LVH- from HV and low-risk HCM from those with intermediate/high-risk score or nonsustained ventricular tachycardia. RESULTS: Compared with HV, subclinical HCM showed mean AT prolongation (P = 0.008) even with normal 12-lead electrocardiograms (ECGs) (P = 0.009), and repolarization was more spatially heterogenous (GRTc: P = 0.005) (23% had normal ECGs). Corrected activation-recovery interval was prolonged in overt vs subclinical HCM (P < 0.001). Mean AT was associated with maximal wall thickness; spatial conduction heterogeneity (GAT) and fractionation were associated with scar (all P < 0.05), and G+LVH+ had more fractionation than G-LVH+ (P = 0.002). The support vector machine discriminated subclinical HCM from HV (10-fold cross-validation accuracy 80% [95% CI: 73%-85%]) and identified patients at higher risk of sudden cardiac death (accuracy 82% [95% CI: 78%-86%]). CONCLUSIONS: In the absence of LVH or 12-lead ECG abnormalities, HCM sarcomere gene mutation carriers express an aberrant EP phenotype detected by ECGI. In overt HCM, abnormalities occur more severely with adverse structural change and positive genetic status.

Finding unveiled: Culex thalassius (Diptera: Culicidae), a new mosquito species emerges in the Cabo Verde archipelago.

Mosquito-borne diseases can pose significant burdens. In many countries, they pose a risk to national economies and the well-being of humans and animals. To mitigate this, mosquito surveillance is crucial to assess the real and potential transmission of mosquito-borne diseases. Between 2020 and 2023, mosquito larvae were collected from both indoor and outdoor breeding sites in urban and rural areas of 4 municipalities of Santiago and Boavista Islands in Cabo Verde. Mosquitoes were identified morphologically and by polymerase chain reaction-based techniques that targeted the mitochondrial cytochrome C oxidase subunit I sequence. During this period, 6,825 breeding sites were assessed, and of 8,094 mosquito specimens screened, 194 specimens of Culex thalassius were identified for the first time in the country in 4 municipalities of Santiago and Boavista Islands. This new finding highlights the importance of including entomological surveillance in health systems. Although this species has only been detected on a few islands, it is important to continuously monitor it to determine its distribution, spread/dispersal, density, and potential involvement in pathogen transmission.

The impact of a health promotion program on toddlers' socio-emotional development: a cluster randomized study.

BACKGROUND: The first 3 years of life are a critical period for the development of socio-emotional skills, highlighting the importance of socio-emotional development in early childhood. This study aimed to evaluate the effectiveness of a health promotion intervention program on the socio-emotional development of children aged 12 to 42 months during the COVID-19 pandemic. METHODS: A total of 344 children from 15 childcare centers participated in this study, with six centers in the intervention group and nine in the control group. Childcare teachers in the intervention group received a 6-month training program aimed at promoting healthy lifestyles, including topics such as diet, sleep, physical activity, and sedentary behavior. Sociodemographic and anthropometric measures were assessed at baseline, and socio-emotional development was assessed using the Bayley Scales of Infant and Toddler Development - Third Edition (Bayley-III) at baseline and post-intervention. RESULTS: After the intervention, a significant difference in socio-emotional development was observed between children with mothers of varying education levels. Specifically, children whose mothers had lower education levels demonstrated significantly greater socio-emotional development (B = 19.000, p = 0.028) compared to the control group. In contrast, there was no significant difference in socio-emotional development among children with mothers from higher education levels. CONCLUSION: These findings suggest that intervention programs for childcare teachers can effectively promote healthy socio-emotional development in children from socioeconomically disadvantaged backgrounds. Future intervention programs should consider tailoring their approaches to target disadvantaged populations. TRIAL REGISTRATION: This cluster randomized controlled trial was registered in the Clinical Trials database/platform on 09/09/2019 (number NCT04082247).

Diastology in the intensive care unit: Challenges for the assessment and future directions.

Myocardial dysfunction is common in patients admitted to the intensive care unit (ICU). Septic disease frequently results in cardiac dysfunction, and sepsis represents the most common cause of admission and death in the ICU. The association between left ventricular (LV) systolic dysfunction and mortality is not clear for critically ill patients. Conversely, LV diastolic dysfunction (DD) seems increasingly recognized as a factor associated with poor outcomes, not only in sepsis but also more generally in critically ill patients. Despite recent attempts to simplify the diagnosis and grading of DD, this remains relatively complex, with the need to use several echocardiographic parameters. Furthermore, the current guidelines have several intrinsic limitations when applied to the ICU setting. In this manuscript, we discuss the challenges in DD classification when applied to critically ill patients, the importance of left atrial pressure estimates for the management of patients in ICU, and whether the study of cardiac dysfunction spectrum during critical illness may benefit from the integration of left ventricular and left atrial strain data to improve diagnostic accuracy and implications for the treatment and prognosis.

Bacaba, Pracaxi and Uxi Oils for Therapeutic Purposes: A Scoping Review.

Fruits such as bacaba (Oenocarpus bacaba Mart), pracaxi (Pentaclethra macroloba Kuntze) and uxi (Endopleura uchi (Huber) Cuatrec), from the Amazon rainforest, are potentially interesting for studies of natural products. The current article aims at mapping and characterizing studies on the bacaba, pracaxi and uxi species. This review reports the main bioactive compounds identified in these species and discusses their therapeutic potential. Searches were performed in MEDLINE (Via Pubmed) and Web of Science. Thirty-one studies that described or evaluated the development of formulations aimed at the therapeutic use of the species were included. The findings suggest that species have the potential for the development of pharmaceutical formulations due to their therapeutic properties. However, further studies are required to assess safety and efficacy of these products. Therefore, it is suggested that new research studies propose strategies so that technological development is based on awareness and preservation of the biome.

Sleep duration and cardiorespiratory fitness in adolescents: Longitudinal analysis from the LabMed study.

PURPOSE: We aimed to investigate longitudinal associations between sleep duration and cardiorespiratory fitness, in adolescents. METHODS: Sleep duration was self-reported and cardiorespiratory fitness was assessed by the 20 m shuttle run test, both at baseline and follow-up (2-year follow-up). Participants were 734 Northern Portuguese adolescents (349 girls), aged 14.6 ± 1.8 years, from the LabMed study. RESULTS: Significant decreases were found between baseline and follow-up for sleep duration, whereas for cardiorespiratory fitness there was an increase. Adolescents with short sleep duration at baseline had lower cardiorespiratory fitness at follow-up, comparing to those meeting the sleep guidelines (odds ratio [OR] = 0.506, 95% confidence interval [CI]: 0.326-0.785; p = .002 for whole week; OR = 0.597, 95% CI: 0.407-0.875; p = .008 for weekdays). Girls who were short sleepers at baseline had lower odds of having a healthy cardiorespiratory fitness at follow-up, comparing to those meeting the sleep guidelines (OR = 0.311, 95% CI: 0.158-0.613; p < .001 for whole week; OR = 0.469, 95% CI: 0.262-0.838; p = .011 for weekdays). No significant associations between sleep duration and cardiorespiratory fitness were found for boys. DISCUSSION: There was a significant longitudinal association between short sleep duration and lower cardiorespiratory fitness levels, particularly in girls. Future interventions targeting adolescents' sleep duration should acknowledge behavioral differences between genders, as well as different behaviors adopted by boys ang girls, specifically on weekends.

Occurrence and predictors of delirium in critically ill older patients: a prospective cohort study.

Objectives: This study aims to analyze the occurrence of delirium in critically ill older patients and to identify predictors of delirium. Methods: This prospective study included critically ill older patients admitted into level II units of Intensive Care Medicine Department of a University Hospital. Patients with Glasgow Coma Scale score ≤11, traumatic brain injury, terminal disease, history of psychosis, blindness/deafness, or inability to understanding/speaking Portuguese were excluded. The Confusion Assessment Method-Short Form (CAM-4) was used to assess the presence of delirium. Results: The final sample (n = 105) had a median age of 80 years, most being female (56.2%), widowed (49.5%), and with complete primary education (53%). Through CAM-4, 36.2% of the patients had delirium. The delirium group was more likely to have previous cognitive decline (48.6% vs 19.6%, P = .04) and severe dependency in instrumental activities of daily living (34.3% vs 14.8%, P = .032), comparing with patients without delirium. The final multiple logistic regression model explained that patients with previous cognitive decline presented a higher risk for delirium (odds ratio: 4.663, 95% confidence Interval: 1.055-20.599, P = .042). Conclusions: These findings corroborate previous studies, showing that cognitive decline is an independent predictor for delirium in older patients. This study is an important contribution for the knowledge regarding the predictors of delirium. The recognition of these factors will help to identify patients who are at high risk for this syndrome and implement early screening and prevention strategies. However, further studies with larger samples, recruited from other clinical settings as well as analyzing other potential factors for delirium, will be needed.

Duodenal lipoma - An unusual finding, location and presentation.

An 82-year-old man was admitted for acute cholangitis. He presented with jaundice and elevated hepatic cholestasis enzymes and C-reactive protein. Abdominal ultrasound and CT scan showed no evidence of gallstones and the main bile duct had 6 mm of diameter. Broad-spectrum antibiotic therapy was initiated and the patient was referred for Endoscopic Retrograde Cholangiopancreatography. During duodenoscopy, a pedunculated subepithelial lesion, measuring approximately 20-30 mm, and suggestive of being a lipoma was found, obstructing the papillary orifice and preventing its access. It was then removed using a diathermic snare. Subsequent cholangiography confirmed the absence of gallstones or any other cause of biliary obstruction. Histopathological analysis confirmed that the lesion was a duodenal lipoma. The patient evolved favorably and had no subsequent episodes of jaundice or cholangitis during follow-up.

Prática baseada em evidências: incorporando pesquisas na prática clínica / Evidence-based practice: incorporating research into clinical practice

Evidências Científicas (ECs) configuram-se como "resultados de pesquisas científicas", realizadas através de procedimentos que incorporaram critérios de validade, isto é, viabilidade (F-feasibility), adequação (A-appropriateness), significado (M-meaning) e efetividade (E-effectiveness) das práticas de saúde, levando-se em conta todasas possíveis fontes de vieses. O termo Prática Baseada em Evidências (PBE) foi cunhado entre as décadas de 70 e 80, sendo originário do movimento da Medicina Baseada em Evidências (MBE), quando foi proposta uma hierarquia dos níveis de ECs, de modo a direcionar a busca das melhores ECs disponíveis para a tomada de decisões na prática clínica. No ano de 2002, enfermeiras engajadas na prática clínica e em pesquisa estabeleceram um modelo para implementação da PBE, o "Advancing Research and Clinical Practice through Close Collaboration(ARCC)", com o intuito de aprimorar e melhor integrar a pesquisa à prática clínica, atrelando aos cuidados de saúde locorregionais e nacionais. Assim, a PBE consiste em uma abordagem ancorada na resolução de problemas para prover o cuidado em saúde que integra as melhores ECs disponíveis provenientes de estudos bem delineados, e combina com as preferências e valores do paciente e a expertisedo profissional de saúde. Para a implementação da PBE na prática clínica, épreciso que o profissional de saúde mantenha a atitude questionadora de modo a transformar a prática clínica. O fio condutor da PBE éa utilização de resultados de pesquisas na prática. Nesse sentido, o movimento de Enfermagem Baseada em Evidências emerge como um elo que interliga as melhores ECs e sua aplicação na prática clínica, primando pela tomada de decisão para um cuidado cientificamente qualificado e seguro. Na prática do enfermeiro, a aplicação da PBE consiste em sete passos: 1) elaboração da questão clínica; 2) busca de ECs; 3) avaliação crítica das ECs recuperadas no processo de busca; 4) tomada de decisões com base nas melhores ECs; 5) avaliação dos resultados da decisão clínica a ser implementada; 6) mudanças com base nas ECs disponíveis; 7) disseminação dos resultados da decisão clínica/mudança da práxis.

Scientific Evidence (ScE) is configured as "results of scientific research", carried out through procedures that incorporated validity criteria, that is, feasibility (F), appropriateness (A), meaning (M) and effectiveness (E) of health practices, taking into consideration all possible sources of bias.The term Evidence-Based Practice (EBP) was created between the 1970s and 1980s, originating from the Evidence-Based Medicine (EBM) movement, where a hierarchy of levels of ScE was proposed, in order to direct the search for best available ScE for decision-making in clinical practice.In 2002, nurses engaged in clinical practice and research established a model for the implementation of EBP, the "Advancing Research and Clinical Practice through Close Collaboration (ARCC)", with the aim of improving and better integratingresearch into clinical practice, linking local and national health care actions. Thus, EBP consists of a problem-solving approach to providing health care actions that integrate the best available ScE from well-designed studies, and combines with the patient's preferences and values and the health professional's expertise. In order to consolidate the implementation of EBP in clinical practice, the health professional must maintain a questioning attitude in such a way as to transform clinical practice. The guiding principle of EBP is the use of research results in practice. In this sense, the Evidence-Based Nursing movement emerges as a link that connects the best ScE and its application in clinical practice, focusing on decision-making for care scientifically qualified and safe. In nursing practice, the application of EBP consists of seven steps: 1) elaboration of the clinical question; 2) search for ScE; 3) critical evaluation of the ScE retrieved in the search process; 4) decision-making based on the best ScE; 5) evaluation of the results of the clinical decision to be implemented; 6) changes based on the available ScE; 7) dissemination of the results of the clinical decision/praxis change.

Is the association between sleep and socio-emotional development mediated by weight in toddlers aged 12 to 36 months?

Introduction: Childhood is an important stage for socio-emotional development. Understanding the associations of lifestyle habits with the healthy development of social and emotional skills is crucial for better interventions early in life. This study aims to analyze the association between sleep and socio-emotional development in toddlers aged 12 to 36 months and examine whether weight mediated these associations. Methods: This study is part of a cluster randomized controlled trial developed in Portuguese childcare centers. A sample of 344 children (176 females) enrolled in the study. Participants' anthropometrics were measured while at childcare centers using standardized procedures. Body mass index (BMI) was computed as the body weight/height2 (kg/m2) ratio. Sleep quality was collected with the Tayside Children's Sleep Questionnaire, a 10-item scale that evaluates the child's ability to initiate and maintain sleep. Two additional questions regarding sleep duration were added. Parental questionnaires assessed the child's sex and date of birth, socioeconomic status, and total energy intake (TEI). Motor (fine and gross) was assessed using Bayley-III scales and socio-emotional (SE) by the Greenspan Social-Emotional Growth Chart questionnaire. Linear regression models were used to examine the associations between sleep (duration and quality) and SE with adjustments for sex, age, BMI, mothers' education, motor development, and TEI. Mediation analysis was conducted using path analysis. Results: SE development was significantly associated with nighttime sleep duration even when adjusted for confounders (ß = 0.223; 95% CI: 0.001, 0.004 and ß = 0.168; 0.0003, 0.003; respectively). Sleep quality was not significantly associated with SE development, and the weight did not explain the associations between sleep and SE development. Conclusion: This study supports that sleep duration is directly associated with SE development in toddlers. From a public health perspective, sleep duration should be prioritized in intervention programs to improve socio-emotional development early in life.

Paraneoplasic Behçet's Syndrome associated with Chronic Myeloid Leukemia.

A 49-year-old man presented with a three-week history of abdominal pain, bloody diarrhoea and fever. Reported oral ulcers, weight loss and asthenia, as well as papulo-pustular lesions on his limbs and a recurrent ulcer in the lip (Fig.1) in the previous year. During hospitalization, he developed pathergy at venipuncture sites and painful scrotum ulcers. Laboratory showed pancytopenia and elevated CRP. Viral and autoimmune tests were negative. Abdominal CT revealed thickening of the ileocecal region with adenopathies. Blood smear and myelogram were compatible with Chronic Myeloid Leukemia (CML). Bone marrow culture and BK were negative. Karyotype revealed no changes, namely, no trisomy of the 8th. Ileocolonoscopy revealed aphthoid erosions of the ileocecal mucosa and ovoid punched-out cecal ulcers. Biopsies showed intense chronic inflammation in the lamina propria and submucosa with erosions and ulcers. Thus, presenting 5 points in the International Criteria for Behçet's Disease, this diagnosis was assumed as a paraneoplastic manifestation of CML.
