Autoimmune neutropenia associated with influenza virus infection in childhood: a case report.

BACKGROUND: Although neutropenia is relatively frequent in infants and children and is mostly a benign condition with a self-limited course, it can lead to life-threatening severe infections. Autoimmune neutropenia is a relatively uncommon hematological disorder characterized by the autoantibody-induced destruction of neutrophils. It is usually triggered by viral infections with very few documented cases after influenza virus. CASE PRESENTATION: An 8-month-old male infant presented at the emergency room with a 5-days history of fever up to 39.7 °C, cough and runny nose. In the blood test performed, severe neutropenia was diagnosed (neutrophils 109/µL). A nasopharyngeal aspirate revealed a positive rapid test for Influenza A. Serum antineutrophil antibodies were determined with positive results. Neutropenia targeted panel showed no mutations. Despite maintenance of severe neutropenia for 9 months the course was uneventful without treatment. CONCLUSIONS: When severe neutropenia is diagnosed and confirmed, it is essential to rule out some potential etiologies and underlying conditions, since the appropriate subsequent management will depend on it. Although autoimmune neutropenia triggered by viral infections has been widely reported, it has seldom been reported after influenza infection. The benign course of the disease allows a conservative management in most cases.

Chorea as the presenting feature of acute rheumatic fever in childhood; case reports from a low-prevalence European setting.

BACKGROUND: Despite a notable decrease in acute rheumatic fever (ARF) incidence in the past few decades, there are still cases in our setting. Sydenham chorea (SC) may be the initial manifestation for this condition in childhood in a significant proportion of children. We report two cases of choreoathetosis in children as the first manifestation of ARF. CASE PRESENTATION: A previously healthy 8-year-old boy presented with right hemichorea with a predominance in the brachial region, orofacial dyskinesias and speech difficulties for the past 2 weeks. The only medical history of interest was a common catarrhal illness 3 weeks before and nonspecific bilateral tenosynovitis in both feet since a year prior. A brain computerized tomography was normal and the echocardiogram showed mild mitral and aortic regurgitation, meeting ARF criteria. He demonstrated clinical improvement with treatment based on prednisone and carbamazepine. The second patient was a 10-year-old girl with choreic movements of the right half of the body and repetitive right eye closure of 1 week duration. She had symptoms of fever and rash the previous week and pharyngitis that resolved without antibiotic 2 months before. Blood tests revealed elevated C reactive protein (12 mg/dl) and erythrocyte sedimentation rate (96 mm/h). Brain magnetic resonance was normal and echocardiogram showed left ventricle dilation and mild mitral regurgitation, leading to the diagnosis of ARF. Due to neurological involvement, she received corticosteroids and intravenous immunoglobulin treatment, with worsening of neurological symptoms that required valproic acid with remission of the hemichorea. In addition skin lessions compatible with erythema marginatum appeared on the upper limbs. CONCLUSIONS: SC should be the main diagnostic consideration in cases of hemichorea with normal neuroimaging in children. The cases reported highlight the need to maintain a high index of suspicion even in settings where incidende of ARF is low and the need to perform cardiological investigations in all patients with suspected SC, due to the possibility of subclinical valve lesions. Good adherence to secondary prophylaxis is crucial to avoid chorea relapses and worsening valve disease.

International Adoption of Children with Special Needs in Spain.

International adoption has declined in recent years, although the adoption of children with special needs has arisen. We aim to describe our experience in the international adoption of children with special needs and to analyze the concordance between the pathologies included in pre-adoption reports and the diagnosis made upon arrival. We conducted a retrospective descriptive study including internationally adopted children with special needs evaluated at a reference Spanish unit between 2016 and 2019. Epidemiological and clinical variables were collected from medical records, and pre-adoption reports were compared to established diagnoses following their evaluation and complementary tests. Fifty-seven children were included: 36.8% females, a median age of 27 months [IQR:17-39], mostly coming from China (63.2%) and Vietnam (31.6%). The main pathologies described in the pre-adoption reports were congenital surgical malformations (40.3%), hematological (22.6%), and neurological (24.6%). The initial diagnosis that motivated the international adoption via special needs was confirmed in 79% of the children. After evaluation, 14% were diagnosed with weight and growth delay, and 17.5% with microcephaly, not previously reported. Infectious diseases were also prevalent (29.8%). According to our series, the pre-adoption reports of children with special needs appear accurate, with a low rate of new diagnoses. Pre-existing conditions were confirmed in almost 80% of cases.

Long-term evolution in liver disease markers and immune and lipid profiles in vertically HIV/HCV-coinfected youths with sustained viral response after direct-acting antivirals therapy.

This study aimed to analyse the long-term effect of direct-acting antivirals (DAAs) in vertically acquired HIV/HCV-coinfected youths. We performed a multicentre, longitudinal and observational study within the Spanish Cohort of HIV-infected children and adolescents and vertically HIV-infected patients transferred to Adult Units (CoRISpe-FARO). We included HIV/HCV-coinfected youths (n = 24) that received DAAs between 2015 and 2017 with successful sustained viral response (SVR) with a subsequent follow-up of at least three years. Long-term evolution in liver disease severity and haematologic markers, lipid and immune profiles after SVR were assessed. Study times were the start date of DAAs treatment (baseline, T0) and 1, 2, 3, 4 and 5 years after SVR (T1, T2, T3, T4 and T5, respectively). We observed global improvements in liver function data that persist over time and a favourable haematologic and immune outcome at the long-term including a constant augment in leucocytes, neutrophils, neutrophils to lymphocytes ratio (NLR) and CD4/CD8 ratio over-time. Regarding the lipid profile, we found a significant increase in total cholesterol T2, total cholesterol/high-density lipoprotein (HDL) ratio at T4, triglycerides at T5, low-density lipoprotein (LDL) over time, and a decrease in HDL in all patients but with marked higher levels in the subgroup receiving anti-HIV Protease Inhibitor (PI)-based regimens. Comparisons of vertically HIV/HCV-coinfected youths after SVR at 3-year follow-up and a control group of vertically HIV-monoinfected youths never infected by HCV showed no significant differences in most variables analysed, suggesting a possible normalization in all parameters.

Clinical characteristics of children hospitalized for COVID-19.

Introduction: Most SARS-CoV2 infections in the pediatric population are asymptomatic or with mild symptoms, with a minimal proportion of severe cases described as SARS-CoV2-associated multi-system inflammatory syndrome (MIS-C).The objective was to describe the clinical and epidemiological characteristics of pediatric patients admitted with confirmed diagnosis of SARS-CoV2 infection from the beginning of the pandemic until May 2021. Methods: Retrospective observational study of pediatric patients hospitalized with confirmed COVID-19, in a tertiary hospital. Epidemiological and clinical data, additional tests, treatments administered and evolution were collected. Results: 30 patients were included, classified into 3 groups according to diagnosis: respiratory infection, MIS-C and compatible symptoms. The patients with pneumonia were associated with age older, comorbidities and lymphopenia. MIS-C were more serious patients, with marked laboratory involvement and greater admission to PICU. Most of these were secondary cases of contact in the family environment. Discussion: The most frequent clinical manifestations of COVID-19 in children are mild-moderate respiratory with good evolution. MIS-C is another form of expression of SARS-COV2 infection of greater severity, but usually with good prognosis after early diagnosis and frequent PICU admission.

Métodos: Estudio retrospectivo observacional de pacientes pediátricos ingresados con diagnóstico de COVID-19, de un hospital terciario. Se recogieron datos demográficos, clínicos, pruebas complementarias, tratamiento administrado y evolución. Resultados: Se incluyeron 30 pacientes, clasificándose en 3 grupos según diagnóstico: Infección respiratoria, SIM-PEDs y síntomas compatibles. Los pacientes con neumonía asociaban mayor edad, comorbilidades y linfopenia. SIM-PEDs fueron pacientes más graves, con afectación analítica marcada y mayor ingreso en UCIP. La mayoría eran casos secundarios de contacto en el entorno familiar. Discusión: Los cuadros clínicos de COVID-19 más frecuentes en niños son respiratorios leves-moderados con buena evolución. SIM-PEDs es otra forma de expresión de infección por SARS-COV2 de mayor gravedad, pero habitualmente con buen pronóstico tras diagnóstico precoz y requiriendo frecuentemente ingreso en UCIP.

SARS-CoV-2 Infection in Children and Adolescents Living With HIV in Madrid.

Multicenter study designed to describe epidemiologic and clinical characteristics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) positive cases registered among children and adolescents living with HIV (CALWH). SARS-CoV-2 infection was confirmed in 13.3% of CALWH, with all patients presenting mild symptoms, and the outcome was good in all patients. None of the HIV- and antiretroviral treatment-related variables studied were associated with greater infection risk or could be considered protective.

Value of advanced interatrial block in the diagnosis of the ischemic stroke's aetiology: A cohort study.

INTRODUCTION AND OBJECTIVES: Advanced interatrial block has been linked with atrial fibrillation (AF) (Bayes syndrome). On the other hand, the aetiology of the stroke remains unknown in approximately 20-25% of patients admitted due to ischaemic stroke. The aim of this study was to evaluate whether advanced interatrial block and CHADS2-VASC scale is linked to AF in patients admitted due to ischaemic stroke without previous AF history. METHODS: A prospective analysis of consecutive in-hospital patients admitted with ischemic stroke between January/2018 and April/2019 in a stroke hospital was performed. Patients had to be in sinus rhythm at admission and without previous history of AF/atrial flutter. During follow up patients receive the usual care. RESULTS: A total of 236 patients were included. The median follow-up was 540 days (407-695). 19 patients (8.1%) had advanced interatrial block at admission. Advanced interatrial block was associated with the diagnosis of AF during follow up (5 (26.3%) Vs 21 (9.7%) p=0.027). A CHADS2-VASC score>4 at admission was also associated with AF diagnosis during follow up (23(14.6%) vs 3(3.9%) p=0.009). CONCLUSION: This study confirms the association of advanced interatrial block and CHADS2-VASC>4 at admission with the diagnosis of AF during follow up in patients with ischemic stroke. This association could have important implications in patients with ischemic stroke who present advanced interatrial block and without previous history of AF.

Clinical and Epidemiologic Characteristics of a Cohort of HIV-Infected Mother-Infant Pairs During 21 Years.

BACKGROUND: HIV infection continues to be a worldwide public health problem. After the introduction of effective preventive measures, perinatal transmission dramatically decreased. Our aim was to assess the sociodemographic changes in pregnant women living with HIV infection and trends in perinatal transmission rates over time. SETTING: The Madrid cohort of HIV-infected mother-infant pairs is a multicenter, prospective, observational, and cohort study that collects information on HIV-infected pregnant women and their children. METHODS: Information on clinical-epidemiological characteristics of HIV-infected pregnant women until delivery and their children from 9 public hospitals was included. Data were collected from a standardized questionnaire from medical records. The results were classified in 3 periods: period 1 (P1) 2000-2006, period 2 (P2) 2007-2013, and period 3 (P3) 2014-2020. RESULTS: A total of 1521 women living with HIV and 1548 newborns were included. In P1, most mothers (75.8%) were Spanish, whereas in P2 and P3 there was a predominance of foreign origin [62.8% and 70.5% respectively ( P < 0.01)]. The percentage of women with antiretroviral treatment before pregnancy increased significantly in P3 ( P < 0.01). The proportion of Caesarean sections decreased over time ( P < 0.01): 66.2% (n = 472) in P1, 54.9% (n = 245) in P2, and 46.7% (n = 141) in P3. The percentage of preterm and low birth weight newborns showed a statistically significant decrease. Even though there were no statistically significant differences ( P = 0.154), a decrease in cases of perinatal infection was observed (1.6% in P1, 1.3% in P2 and 0.3% in P3). CONCLUSIONS: The epidemiologic characteristics of pregnant women with HIV infection have changed over time in our setting, with an increase of non-Caucasian, heterosexual, and perinatally infected mothers. Although there are still perinatal infections, especially in vulnerable populations such as immigrant women, transmission rate has markedly decreased in recent years and is still of major concern. Prevention measures should be reinforced in the most socially disadvantaged groups.

Eye-of-the-Tiger Sign with an Unexpected Pathological Diagnosis.

BACKGROUND: Clinical diagnosis of atypical parkinsonisms may be challenging. The eye-of-the-tiger sign on brain MRI, typical of neurodegeneration with brain iron accumulation, has been anecdotally observed in cases clinically diagnosed as atypical parkinsonisms. OBJECTIVES: To show how clinical syndromes and even neuroimaging sometimes may lead the neurologist to a misunderstanding, just as to emphasize the important role of pathology to establish the final diagnosis in these cases. METHODS: Clinico-pathological case. RESULTS: A 67-year-old-woman presented with progressive painful stiffness and allodynia in her left arm. On examination, she presented parkinsonism without tremor with greater involvement of left limbs. She developed dystonia, with myoclonic tremor and hypoesthesia involving her left arm, as well as an impairment of balance with falls, a significant axial involvement with disabling rigidity, supranuclear gaze abnormalities, facial dystonia, dysphonia, severe dysphagia, and anarthria. There was no response to levodopa. Syndromic diagnosis and findings on neuroimaging are discussed. Afterwards, the underlying pathology is revealed. CONCLUSIONS: We present the first case of neuropathologically confirmed multiple system atrophy with the eye-of-the-tiger sign on brain MRI. The presence of supranuclear vertical gaze palsy further complicated a correct clinical diagnosis. A pathological postmortem study remains essential to establish a definite diagnosis in atypical parkinsonisms.

Longitudinal survey of humoral and cellular response to SARS-CoV-2 infection in children.

BACKGROUND: Data regarding humoral and cellular response against SARS-CoV-2 in children are scarce. We analysed seroconversion rate, decrease of anti-RBD IgG antibodies over time and T-cell response in paediatric patients who suffered COVID-19. METHODS: Longitudinal study of paediatric patients COVID-19 diagnosed by positive molecular assay in nasopharyngeal swabs. Blood samples were drawn 1-2 months and 6-7 months after acute infection. Anti-RBD IgG were determined using the Alinity® SARS-CoV-2 IgG II Quant assay (Abbott). Cellular immune response was analysed by T-SPOT® SARS-CoV-2 assay kit (Oxford Immunotec Ltd.). RESULTS: 27/39 (69,2%) patients seroconverted. Despite a significant decrease in antibody levels over time (p < 0,01), no children seroreverted between first and second visits. Only 6/16 (37,2%) children under 6 years-old were seropositive compared to 21/23 (91,3%) over 6 years-old (p < 0,01). Highest antibody levels were found in seropositive younger children (p = 0,036). Thirteen (33,3%) children showed T-cell response. Among participants showing humoral response, no cellular response was detected in 14 (51,9%). CONCLUSIONS: Anti-RBD IgG antibodies persistence at 6-7-months after SARS-CoV-2 infection was observed. A different IgG response was found depending on age. As measured by T-SPOT, most patients did not display cellular response 6-7 months after infection.

A Prospective Study of the Serological, Clinical, and Epidemiological Features of a SARS-CoV-2 Positive Pediatric Cohort.

Background: SARS-CoV-2 was a global pandemic. Children develop a mild disease and may have a different rate of seroconversion compared to adults. The objective was to determine the number of seronegative patients in a pediatric cohort. We also reviewed the clinical−epidemiological features associated with seroconversion. Methods: A multicenter prospective observational study during September−November 2020, of COVID-19, confirmed by reverse transcription-polymerase chain reaction. Data were obtained 4−8 weeks after diagnosis. Blood samples were collected to investigate the humoral response, using three different serological methods. Results: A total of 111 patients were included (98 symptomatic), 8 were admitted to hospital, none required an Intensive Care Unit visit. Median age: 88 months (IQR: 24−149). Median time between diagnosis and serological test: 37 days (IQR: 34−44). A total of 19 patients were non-seroconverters when using three serological techniques (17.1%; 95% CI: 10.6−25.4); most were aged 2−10 years (35%, p < 0.05). Univariate analysis yielded a lower rate of seroconversion when COVID-19 confirmation was not present amongst household contacts (51.7%; p < 0.05). Conclusions: There was a high proportion of non-seroconverters. This is more commonly encountered in childhood than in adults. Most seronegative patients were in the group aged 2−10 years, and when COVID-19 was not documented in household contacts. Most developed a mild disease. Frequently, children were not the index case within the family.

Safety and Experience With Combined Antiretroviral Prophylaxis in Newborn at High-risk of Perinatal HIV Infection, in a Cohort of Mother Living With HIV-infant Pairs.

BACKGROUND: Perinatal transmission of HIV has dramatically decreased in high-income countries in the last few years with current rates below 1%, but it still occurs in high-risk situations, mainly pregnant women with late diagnosis of infection, poor antiretroviral adherence and a high viral load (VL). In these high-risk situations, many providers recommend combined neonatal prophylaxis (CNP). Our aim was to evaluate the safety and toxicity of CNP in infants deemed at high-risk of HIV infection among mother-infant pairs in the Madrid Cohort. MATERIALS AND METHODS: Prospective, multicenter, observational cohort study between years 2000 and 2019. The subgroup of newborns on CNP and their mothers were retrospectively selected (cohort A) and compared with those who received monotherapy with zidovudine (cohort B). Infants with monotherapy were classified according to treatment regimes in long (6 weeks) and short (4 weeks) course. RESULTS: We identified 227 newborns (33.3% preterm and 7 sets of twins) with CNP. A maternal diagnosis of HIV-1 infection was established during the current pregnancy in 72 cases (36.4%) and intrapartum or postpartum in 31 cases (15.7%). Most infants received triple combination antiretroviral therapy (65.6%; n = 149). The perinatal transmission rate in cohort A was 3.5% (95% confidence interval: 1.13%-5.92%). Infants from cohort A developed anemia (26.1% vs. 19.4%, P = 0.14) and neutropenia more frequently at 50-120 days (21.4% vs. 10.9%, P < 0.01), without significant differences in grade 3 and 4 anemia or neutropenia between the two cohorts. There were no differences in increased alanine aminotransferase. Neutropenia was more common in the long zidovudine regimes. CONCLUSIONS: Our findings provide further evidence of the safety of CNP in infants with high-risk of HIV-1 perinatal transmission.

Upregulation of polycistronic microRNA-143 and microRNA-145 in colonocytes suppresses colitis and inflammation-associated colon cancer.

Because ADAM17 promotes colonic tumorigenesis, we investigated potential miRNAs regulating ADAM17; and examined effects of diet and tumorigenesis on these miRNAs. We also examined pre-miRNA processing and tumour suppressor roles of several of these miRNAs in experimental colon cancer. Using TargetScan, miR-145, miR-148a, and miR-152 were predicted to regulate ADAM17. miR-143 was also investigated as miR-143 and miR-145 are co-transcribed and associated with decreased tumour growth. HCT116 colon cancer cells (CCC) were co-transfected with predicted ADAM17-regulating miRNAs and luciferase reporters controlled by ADAM17-3'UTR. Separately, pre-miR-143 processing by colonic cells was measured. miRNAs were quantified by RT-PCR. Tumours were induced with AOM/DSS in WT and transgenic mice (Tg) expressing pre-miR-143/miR-145 under villin promoter. HCT116 transfection with miR-145, -148a or -152, but not scrambled miRNA inhibited ADAM17 expression and luciferase activity. The latter was suppressed by mutations in ADAM17-3'UTR. Lysates from colonocytes, but not CCC, processed pre-miR-143 and mixing experiments suggested CCC lacked a competency factor. Colonic miR-143, miR-145, miR-148a, and miR-152 were downregulated in tumours and more moderately by feeding mice a Western diet. Tg mice were resistant to DSS colitis and had significantly lower cancer incidence and tumour multiplicity. Tg expression blocked up-regulation of putative targets of miR-143 and miR-145, including ADAM17, K-Ras, XPO5, and SET. miR-145, miR-148a, and miR-152 directly suppress colonocyte ADAM17 and are down-regulated in colon cancer. This is the first direct demonstration of tumour suppressor roles for miR-143 and miR-145 in an in vivo model of colonic tumorigenesis.

Mortality in Perinatally HIV-infected Adolescents After Transition to Adult Care in Spain.

INTRODUCTION: After the introduction of combination antiretroviral treatment, (ART) mortality in HIV-infected patients has dramatically decreased. However, it is still high in patients at risk, as adolescents transitioning to adult care (AC) without virologic control. The aim of this study was to characterize mortality and comorbidities of perinatally infected HIV (PHIV) patients after transition to AC. METHODS: A multicenter retrospective study from patients included in the CoRISpe-FARO Spanish cohort was conducted. PHIV patients who died after transition to AC between 2009 and 2019 were included. Clinical, immunovirologic characteristics, treatments received, comorbidities and causes of death were described. RESULTS: Among 401 PHIV patients, 14 died (3.5%). All were Spanish, 11/14 (78.6%) women. The median age at diagnosis was 1.5 years (interquartile range [IQR] 0.5-3.9), at transfer to AC was 18 years [16.1-19.9] and at death was 25.8 years [23.6-27.1]. In pediatric units [pediatric care (PC)], CD4+ nadir was 85 cells/µL [IQR 9.7-248.5] and 6/14 patients were classified as C-clinical stage. During AC, all patients were on C-clinical stage and CD4+ nadir dropped to 11.5 cells/µL [4.5-43.3]. cART adherence was extremely poor: in PC, 8/14 patients registered voluntary treatment interruptions; only one had undetectable VL at transition. In AC, 12/14 patients stopped treatment 2 or more periods of time. All deaths were related to advanced HIV disease. Mental health disorders were observed in 7/14 (50%). Main complications described: recurrent bacterial infections (57.1%), wasting syndrome (42.9%), esophageal candidiasis (28.6%) and Pneumocystis jirovecii pneumonia (28.6%). Four women had 11 pregnancies; 5 children were born (none infected). CONCLUSIONS: Young adults PHIV infected who transition to AC without virologic suppression or proven ability to adhere to ART are at high risk of mortality. Mortality was noted as a consequence of advanced HIV disease, frequent mental health problems and poor adherence to ART.

SURINPARK: Safinamide for Urinary Symptoms in Parkinson's Disease.

BACKGROUND: Urinary symptoms are common, disabling and generally unresponsive to treatment in Parkinson´s disease (PD). Safinamide is approved as an add-on therapy to levodopa to improve fluctuations. METHODS: Retrospective analysis of electronic records of nondemented PD patients seen consecutively in a Movement Disorders Unit (November 2018-February 2019). All were assessed with Scale for Outcomes in Parkinson's disease for Autonomic Symptoms-Urinary subscale (SCOPA-AUT-U) by the attending neurologist, and a month afterwards by an independent researcher blinded to treatment and clinical records in a routine clinical practice setting. Clinical variables were compared among patients who were prescribed safinamide (SA+) for the treatment of motor fluctuations and those with different treatment regimes (SA-). RESULTS: From 169 patients screened initially, 54 were excluded due to severe incontinence, absence of urinary symptoms or previous safinamide treatment. Thirty-five patients were included in SA+ and 79 in SA-. Both groups were comparable in terms of clinical variables, except in basal urinary symptoms, with more severity in the SA+ group. In the follow-up assessment, total SCOPA-AUT-U, as well as urgency, incontinence, frequency and nocturia subscales improved significantly in the SA+ group, while the SA- group remained unchanged. CONCLUSIONS: Safinamide could be helpful in the improvement of urinary symptoms in PD.

Tuberculosis in the paediatric population of Madrid in the last 26 years. / Enfermedad tuberculosa en población pediátrica en Madrid en los últimos 26 años.

INTRODUCTION: Tuberculosis (TB) continues to be a serious public health problem and establishing a definitive diagnosis among children is extremely challenging. Pulmonary tuberculosis is the most prevalent form, with children under the age of 2 years being at greatest risk of severe and disseminated forms. The aim of this study was to describe TB among children in Spain in recent years. PATIENTS AND METHODS: A retrospective study of paediatric patients diagnosed with TB in two hospitals of the Community of Madrid over a 26-year period (1991-2017). Epidemiological and clinical variables, additional tests and treatments received were analysed. RESULTS: 170 children were included. The two most-affected age groups were infancy and adolescence. 42.9% of patients were immigrant children (South-America or Morocco). The main reasons for consultation were TB contact (20.6%) and fever (15.3%). At diagnosis, 61.8% of cases referred an epidemic environment, and 30.6% were asymptomatic. The Mantoux tuberculin skin test was positive in 92.2% of patients and IGRA was positive in 70.6%. Pulmonary TB was identified in 91.8% of children vs. 8.2% with extrapulmonary forms. Gastric juice culture was positive in 36.9% of cases and three strains resistant to isoniazid were isolated. All patients were cured without complications except one who died. CONCLUSIONS: Pulmonary TB continues to be the most prevalent form among children and presumptive diagnosis (symptoms consistent with positive Mantoux test or suggestive X-ray) is the most common form of diagnosis. It is important to conduct a contact investigation in order to control the spread of TB.

Use of the Cardiovascular Polypill in Secondary Prevention of Cerebrovascular Disease: A Real-Life Tertiary Hospital Cohort Study of 104 Patients.

BACKGROUND: The use of the cardiovascular polypill, a fixed-dose combination treatment, is conceived to improve adherence. However, randomized controlled trials (RCTs) may overestimate it. Studies focusing on cerebrovascular disease and real-life efficacy compared with conventional treatment are lacking. METHODS: This is a retrospective, hospital-based cohort study of acute ischaemic stroke patients who were prescribed a polypill (aspirin 100 mg, atorvastatin 20/40 mg, ramipril 2.5/5/10 mg) versus conventional treatment (aspirin 100 mg and other blood pressure/lipid-lowering agents) in secondary prevention (2017-2018). Clinical records were reviewed 90 days after discharge for stroke recurrence, vascular risk factor control, and safety. Adherence was assessed using the adapted Morisky-Green scale. RESULTS: A total of 104 patients were included (61% male; mean age 69.7 ± 13.9 years); 54 were treated with the polypill and 50 with conventional treatment. No baseline differences in clinical or demographic variables were detected. No recurrences were registered in the polypill group, compared to 1 recurrence in the conventional treatment group. A significant reduction of systolic blood pressure (SBP) was achieved in the polypill group (12.1 mm Hg) compared to the conventional treatment group (6.8 mm Hg) (p = 0.002). No significant differences were detected regarding the goal of LDL cholesterol ≤70 mg/dL (41 vs. 44%). The adverse events were mild and their frequency was similar in the two groups (9 vs. 2%, ns). Adherence was similarly good in the two groups (93 vs. 88%, ns). Polypill group adherence was similar to that reported in a previous meta-analysis of RCTs (93 vs. 84%, ns). CONCLUSION: In our experience, the cardiovascular polypill achieved a higher reduction in SBP levels and was well tolerated. Adherence was similar to that found in the previous literature, which is remarkable given the real-life setting of our study.

Effects of social stress on tumor development in dominant male mice with diverse behavioral activity profiles.

We examined the influence of individual psychological profile and social behavior on tumor development in dominant male mice. Male OF1 mice were subjected to an open field test (OFT) to observe their motor activity and latency. Subsequently, the animals were divided into three groups: Stress-Non-Inoculated (SNI), Stress-Inoculated (SI) and Control-Inoculated (CI). The SI and CI groups were inoculated with tumor cells and the SNI group with vehicle. SNI and SI were exposed to social stress with an anosmic intruder six (T1) and twenty one (T2) days after inoculation and their behavior was analyzed. After T2, subjects were put down and the pulmonary metastatic foci counted. SI developed greater pulmonary metastasis than CI, indicating an effect of stress despite the animal's dominant status. Active animals developed less pulmonary metastasis than their passive counterparts. No differences were found in social behavior at T1. Differences were found, however, in some behavioral categories at T2 between SI and SNI, and between active and passive animals. These differences indicate an effect of tumor development on social behavior that is more evident in passive subjects.

Evolución y características de los ingresos por COVID-19 pediátricos en un hospital terciario

Introducción. La mayoría de infecciones por SARS-CoV2 en población pediátrica cursan asintomáticas o con síntomas leves, con porcentaje mínimo de casos graves descritos como síndrome inflamatorio multisistémico asociado al SARS-CoV2 (SIM-PEDs). El objetivo fue describir las características clínico-epidemiológicas de aquellos pacientes pediátricos ingresados con diagnóstico confirmado de SARS-CoV2, y las posibles diferencias de la enfermedad considerando dos períodos epidemiológicos. Material y métodos. Estudio retrospectivo observacional de pacientes pediátricos ingresados con diagnóstico de COVID-19, de un hospital terciario. Se recogieron de forma consecutiva, entre marzo de 2020 hasta febrero 2022, analizando datos demográficos, clínicos, pruebas complementarias, tratamiento administrado y evolución. Resultados. Se incluyeron 69 pacientes, clasificándose en 6 grupos según diagnóstico. Los pacientes con neumonía asociaban mayor hipoxemia, mayor edad y eran predominantemente varones (p<0.01), con respecto al grupo de infecciones respiratorias sin condensación. SIM-PEDs fueron pacientes más graves, con afectación analítica marcada y mayor ingreso en UCIP. Durante el 2º periodo se observa una tendencia a la disminución de la infección respiratoria (69% al 47%), menor estancia hospitalaria (de 4 a 3 días), y aumento de los ingresos por otra patología (7,7% al 30,6%). Conclusiones. Los cuadros clínicos de COVID-19 más frecuentes en niños son respiratorios leves-moderados con buena evolución. Hay una tendencia a menor duración de estancia hospitalaria y aumento de ingresos por otra patología en pacientes asintomáticos en el segundo periodo. SIM-PEDs es otra forma de expresión de infección por SARS-COV2 de mayor gravedad, pero habitualmente con buen pronóstico tras diagnóstico precoz y requiriendo frecuentemente ingreso en UCIP.

Introduction. Most SARS-CoV2 infections in pediatric population are asymptomatic or have mild symptoms, with a small percentage of severe cases described as SARS-CoV2-associated multisystem inflammatory syndrome (MIS-C). The objective was to describe the clinical-epidemiological characteristics of those pediatric patients admitted with a SARS-CoV2 confirmed diagnosis, and the possible differences in the disease considering two epidemiological periods. Methods. Observational retrospective study of pediatric patients admitted with a diagnosis of COVID-19, from a tertiary hospital. They were collected consecutively, between March 2020 and February 2022, analyzing demographic and clinical data, complementary tests, administered treatment and evolution. Results. 69 patients were included, classified into 6 groups according to diagnosis. Patients with pneumonia associated greater hypoxemia, older age and were predominantly male (p<0.01), with respect to the group of respiratory infections without condensation. MIS-C were more severe patients, with marked analytic involvement and greater admission to the PICU. During the 2nd period, there was a trend towards a decrease in respiratory infection (69% to 47%), a shorter hospital stays (4 to 3 days), and an increase in admissions for another pathology (7.7% to 30,6%). Discussion. The most frequent clinical manifestations of COVID-19 in children are mild-moderate respiratory symptoms with a good prognosis. There is a trend towards a shorter length of hospital stay and an increase in admissions for another pathology in asymptomatic patients in the second period. MIS-C is another form of expression of SARS-COV2 infection of greater severity, but usually with a good prognosis after early diagnosis and frequently requiring PICU admission.
