The nutritional supplement taurine activates p53-dependent and independent tumor suppressor mechanisms in various cellular models of ovarian cancer.

Loss of treatment-induced ovarian carcinoma (OC) growth suppression poses a major clinical challenge because it leads to disease recurrence. Therefore, there is a compelling need for well- -tolerated approaches that can support tumor growth-suppression after therapy is stopped. We have profiled ascites as OC tumor microenvironments to search for potential non-toxic soluble components that would activate tumor suppressor pathways in OC cells. Our investigations revealed that low levels of taurine, a non-proteogenic sulfonic amino acid, were present within OC ascites. Taurine supplementation, beyond levels found in ascites, induced growth suppression without causing cytotoxicity in various OC cells, including chemotherapy-resistant cell clones and patient-derived organoids representing primary or chemotherapy recovered disease. Inhibition of proliferation by taurine was linked to increased mutant or wild-type p53 proteins binding to DNA, induction of p21, and independently of p53, TIGAR expression. Taurine-induced activation of p21 and TIGAR was associated with suppression of cell-cycle progression, glycolysis, and mitochondrial respiration. Expression of p21 or TIGAR in OC cells mimicked taurine-induced growth suppression. Our studies support the potential therapeutic value of taurine supplementation in OC.

Risk of bleeding complications and atrial fibrillation associated with ibrutinib treatment: A systematic review and meta-analysis.

The use of ibrutinib is hampered by major bleeding events and atrial fibrillation. Speculating whether randomized controlled trials might underestimate the risk of adverse events in clinical practice, we conducted a systematic review and meta-analysis studying patients treated in any setting and indication. We systematically searched the literature using MEDLINE and EMBASE databases for case series, cohort studies, or randomized controlled trials and retrieved all data in parallel. Proportions of patients with adverse events were pooled in relevant subgroups using the binominal distribution and Freeman-Tukey double arcsine transformation. Among 2'537 records screened, 85 were finally included, comprising 7'317 patients. Methodological quality according to the Newcastle-Ottawa Scale was rated as moderate to poor with regard to bleeding events and atrial fibrillation; 106 studies were excluded because of missing data at all. Reported events varied substantially between 0 % and 78 % (any bleedings), 0 % and 25 % (major bleedings), and 0 % and 38 % (new-onset atrial fibrillation). Pooled estimates were 28 % (95 % confidence interval 22 %, 34 %), 3 % (2 %, 4 %), and 8 % respectively (7 %, 10 %). The risk of events was higher in studies with an older population, high ibrutinib dosage, thrombocytopenia, antithrombotic treatment, and retrospective studies. In conclusions, reporting of bleeding events and atrial fibrillation varied substantially among studies. These observations, in combination with the estimates obtained, suggest a relevant risk in clinical practice.

Neumonía adquirida en la comunidad: tratamiento ambulatorio y prevención / Community acquired pneumonia in children: Outpatient treatment and prevention

La neumonía adquirida en la comunidad (NAC) en la edad pediátrica ha sufrido, en la última década, una serie de cambios epidemiológicos, clínicos, etiológicos y de resistencias a antibióticos, que obligan a replantear su abordaje terapéutico. En este documento, dos de las principales sociedades de especialidades pediátricas involucradas en el diagnóstico y tratamiento de esta entidad, como son la Sociedad Española de Infectología Pediátrica y la Sociedad Española de Neumología Pediátrica, así como el Comité Asesor de Vacunas de la AEP, proponen unas pautas consensuadas de tratamiento y prevención, con el fin de proporcionar a todos los pediatras una guía actualizada. En esta primera parte del consenso, se aborda el tratamiento de los pacientes sin enfermedades de base relevantes con NAC que no precisan ingreso hospitalario, así como la prevención global de esta patología con vacunas. En un siguiente documento se expondrá el abordaje terapéutico tanto de aquellos pacientes en situaciones especiales como de las formas complicadas de la enfermedad

There have been significant changes in community acquired pneumonia (CAP) in children in the last decade. These changes relate to epidemiology and clinical presentation. Resistance to antibiotics is also a changing issue. These all have to be considered when treating CAP. In this document, two of the main Spanish pediatric societies involved in the treatment of CAP in children, propose a consensus concerning therapeutic approach. These societies are the Spanish Society of Paediatric Infectious Diseases and the Spanish Society of Paediatric Chest Diseases. The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) has also been involved in the prevention of CAP. An attempt is made to provide up-to-date guidelines to all paediatricians. The first part of the statement presents the approach to ambulatory, previously healthy children. We also review the prevention with currently available vaccines. In a next second part, special situations and complicated forms will be addressed

Effectiveness of a mindfulness education program in primary health care professionals: a pragmatic controlled trial.

INTRODUCTION: Burnout is a very prevalent type of stress among health professionals. It affects their well-being, performance, and attitude toward patients. This study assessed the effectiveness of a training program for primary health care professionals designed to reduce burnout and mood disturbance, increase empathy, and develop mindfulness. METHODS: Pragmatic randomized controlled trial with pre- and postintervention measurements of 68 primary health care professionals (43 in the intervention and 25 in the control group) in Spain. The intervention consisted of presentations of clinically relevant topics, mindfulness-based coping strategies, mindfulness practice, yoga, and group discussions (8 sessions of 2.5 hours per week plus a 1-day session of 8 hours). Outcome measures included the Maslach Burnout Inventory, Profile of Mood States, Jefferson Scale of Physician Empathy, Baer's Five Facets Mindfulness Questionnaire, and a questionnaire on changes in personal habits and mindfulness practice. Measurements were performed at baseline and after 8 weeks. RESULTS: The intervention group improved in the 4 scales measured. The magnitude of the change was large in total mood disturbance (difference between groups -7.1; standardized effect-size [SES] 1.15) and mindfulness (difference between groups 11; SES 0.9) and moderate in the burnout (difference between groups -7; SES 0.74) and empathy scales (difference between groups 5.2; SES 0.71). No significant differences were found in the control group. DISCUSSION: Our study supports the use of mindfulness-based programs as part of continuing professional education to reduce and prevent burnout, promote positive attitudes among health professionals, strengthen patient-provider relationships, and enhance well-being.
