Maternal-infant transfer of SARS-CoV-2 antibodies following vaccination in pregnancy: A prospective cohort study.

OBJECTIVES: To measure and evaluate the impact of receiving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines in pregnancy on immunoglobulin G (IgG) and immunoglobulin A (IgA) titres in maternal and infant samples. DESIGN: Prospective cohort study. SETTING: Tertiary obstetric centre. POPULATION OR SAMPLE: 52 pregnant women who received one or more SARS-CoV-2 vaccine doses during pregnancy and their neonates. METHODS: IgG and IgA concentrations against SARS-CoV-2 antigens were measured from samples collected at delivery and 4-6 weeks postpartum and compared using Spearman correlations. MAIN OUTCOME MEASURES: Maternal and infant IgG and IgA titres in response to vaccination and infection in pregnancy. RESULTS: In maternal serum collected at delivery, participants without evidence of prior infection who received 3 + doses of a SARS-CoV-2 vaccine had higher Anti-Spike (S) IgG geometric mean concentrations (log10 AU/mL)(GMC) than those who received 2 doses (3 + Doses = 5.00, 2 Doses = 4.60, p = 0.08). The differences in IgG Anti-S GMC were statistically significant in cord serum, and in postpartum samples of maternal serum, infant serum and breast milk (Cord GMCs: 3 + Doses = 5.32, 2 Doses = 4.98, p < 0.05; Postpartum maternal serum GMCs: 3 + Doses = 5.25, 2 Doses = 4.57, p < 0.001; Postpartum infant serum GMCs: 3 + Doses = 5.10, 2 Doses = 4.72, p = 0.03; Postpartum breast milk GMCs: 3 + Doses = 2.61, 2 Doses = 1.94, p < 0.0001). Among participants with 3 + Doses, those with evidence of SARS-CoV-2 infection had statistically significant higher anti-S IgG GMCs than those without prior infection (Maternal serum at delivery: SARS-CoV-2+=5.65, SARS-CoV-2-=5.00, p = 0.004; Cord: SARS-CoV-2+=5.68, SARS-CoV-2-=5.32, p = 0.02; Postpartum maternal serum: SARS-CoV-2+=5.66, SARS-CoV-2-=5.25, p < 0.001; postpartum infant serum: SARS-CoV-2+=5.50, SARS-CoV-2-=5.10, p = 0.003; Postpartum breast milk: SARS-COV-2+=3.25, SARS-COV-2-=2.61, p = 0.009). Significant positive correlations were found for anti-S IgG titres between paired maternal and infant samples at delivery and postpartum (Delivery: R = 0.91, p < 0.001; postpartum: R = 0.86, p < 0.001). CONCLUSIONS: Receipt of a SARS-CoV-2 vaccine and SARS-CoV-2 infection elicit strong IgG and IgA antibody responses in pregnant women with evidence of transplacental transfer to the fetus.

Development of a Questionnaire on Knowledge, Habits, and Attitudes on Sexually Transmitted Infections in Teenagers and Young Adults / Generación de un cuestionario sobre conocimientos, hábitos y actitudes sobre infecciones de transmisión sexual en adolescentes y adultos jóvenes

Communication with teenagers who are significantly affected by sexually transmitted infections (STIs) is essential for the sake of prevention. The aim of this study is to develop a specific questionnaire for surveying the degree of knowledge, behavior, and attitudes of current teenagers and young adults on STIs to come up with the proper training tools. We conducted the study following the Delphi method, a 2-round critical assessment score (from 1 to 9) of all domains and items. Only domains and items with median scores ≥8 were selected. A total of 8 panelists were involved in this survey. After establishing a median score ≥8, a total of 14 domains and 40 items were eventually selected. This is the first questionnaire ever conducted to study the knowledge, habits, and attitudes of contemporary teenagers and young adults on STIs, and stands as a valuable tool for future training on STI prevention in teenagers and young adults.

High accuracy of a blood ctDNA-based multimodal test to detect colorectal cancer.

BACKGROUND: Detection of circulating tumor DNA (ctDNA) is a minimally invasive and convenient blood-based screening strategy that may increase effectiveness of colorectal cancer (CRC) screening. PATIENTS AND METHODS: A novel multimodal ctDNA-based blood assay that integrates genomics, epigenomics and fragmentomics, as well as proteomics in a refined version, was tested in blood samples from two cohorts: (i) consecutive fecal immunochemical test (FIT)-positive individuals from the CRC Barcelona stool-based screening program; (ii) patients diagnosed with CRC. Primary endpoint was the performance of the test to detect CRC at different tumor-node-metastasis (TNM) stages. Secondary endpoint was the ability of the test to detect advanced precancerous lesions (advanced adenoma or advanced serrated lesion). RESULTS: A total of 623 blood samples were analyzed in the primary analysis. Sensitivity and specificity of the assay to detect CRC was 93% and 90%, respectively. The sensitivity of CRC detection according to TNM stages was 84% for stage I, 94% for stage II and 96% for stage III (70/73) (P< 0.024). Sensitivity to detect advanced precancerous lesions was 23% with a refined version of the test (including protein and updating bioinformatic thresholding). CONCLUSION: A blood-based multimodal ctDNA assay detected CRC with high accuracy. This minimally invasive, accessible and convenient assay may help to increase the effectiveness of CRC screening.

Infecciones de transmisión sexual (ITS) durante el estado de alarma por la pandemia de COVID-19 en España / Sexually Transmitted Infections During the First Wave of the COVID-19 Pandemic in Spain

Objetivo: Describir los cambios en el comportamiento de las ITS durante la situación de alerta sanitaria por la pandemia SARS-CoV-2. Material y métodos: Se recogieron datos demográficos, cronológicos y clínicos de todos los pacientes que solicitaron atención médica por ITS en los hospitales La Paz y Costa del Sol, y en los Centros Sandoval y de Diagnóstico Médico, entre el 14/03/2020 y el 30/06/2020. Resultados: Documentamos 674 casos de ITS. La mediana de edad fue de 33años. El mayor porcentaje de casos se dio en el rango de 30-40años y en hombres que tenían sexo con hombres. Los diagnósticos más frecuentes fueron: proctitis (36,5%), sífilis (16%), uretritis no gonocócica (13,3%) y gonocócica (11,3%), herpes genital (8,8%), vulvovaginitis/cervicitis (8,3%) y condilomas (4,2%). En el 77% de los casos hubo confirmación microbiológica, siendo los microorganismos más frecuentes Chlamydia trachomatis (35,7%), Neisseria gonorrhoeae (31,4%) y Treponema pallidum (17,2%). Se constató un incremento del número de casos de ITS tras el desconfinamiento, explicable por las mayores libertades y el aumento de consultas. Comparando los registros de ITS del Centro Sandoval y del Hospital La Paz en los cuatrimestres de marzo a junio de 2019 frente a 2020, se observó una disminución en 2020 de todos los diagnósticos, de hasta el 81% menos que en 2019.Conclusiones:Las medidas de distanciamiento y limitación de movilidad aparentemente generaron una disminución de la incidencia de ITS, pero sin llegar a una inhibición completa de las conductas sexuales de riesgo (AU)

Objectivs: To describe changes in sexually transmitted infection (STI) diagnoses during the first wave of the COVID-19 pandemic in Spain. Material and methods: We collected demographic, chronological, and clinical data for all patients seen for a possible STI at Hospital La Paz, Centro Sanitario Sandoval, and Centro de Diagnóstico Médico in Madrid and Hospital Costa del Sol in Malaga between March 14, 2020 and June 30, 2020. Results: We identified 674 STI diagnoses. The median age of the patients was 33years. Most cases were observed among people aged 30 to 40years and among men who have sex with men. The most common diagnoses were proctitis (36.5%), syphilis (16%), nongonococcal (13.3%) and gonococcal (11.3%) urethritis, genital herpes (8.8%), vulvovaginitis/cervicitis (8.3%), and genital warts (4.2%). A microbiologically confirmed diagnosis was on record for 77% of cases. The main microorganisms identified were Chlamydia trachomatis (35.7%), Neisseria gonorrhoeae (31.4%) and Treponema pallidum (17.2%). The number of STI diagnoses increased after the easing of lockdown restrictions, which resulted in greater freedom of movement and more consultations. On comparing the 2019 and 2020 STI registries from Centro Sanitario Sandoval and Hospital La Paz for the period March to June, we observed reductions (of up to 81%) in all STI diagnoses. Conclusions: Physical distancing and movement restrictions appear to have resulted in a reduction in the incidence of STIs, although these measures did not completely eliminate sexual risk behaviors (AU)

GEIS-SEHOP clinical practice guidelines for the treatment of rhabdomyosarcoma

Rhabdomyosarcoma (RMS) is the most frequent soft tissue sarcoma (STS) in children and adolescents. In Spain the annual incidence is 4.4 cases per million children < 14 years. It is an uncommon neoplasm in adults, but 40% of RMS are diagnosed in patients over 20 years of age, representing 1% of all STS in this age group. RMS can appear anywhere in the body, with some sites more frequently affected including head and neck, genitourinary system and limbs. Assessment of a patient with suspicion of RMS includes imaging studies (MRI, CT, PET-CT) and biopsy. All patients with RMS should receive chemotherapy, either at diagnosis in advanced or metastatic stages, or after initial resection in early local stages. Local control includes surgery and/or radiotherapy depending on site, stage, histology and response to chemotherapy. This guide provides recommendations for diagnosis, staging and treatment of this neoplasm (AU)
