Clinical practice update of antifungal prophylaxis in immunocompromised children.

Due to the rise in the number and types of immunosuppressed patients, invasive fungal infections (IFI) are an increasing and major cause of morbidity and mortality in immunocompromised adults and children. There is a broad group of pediatric patients at risk for IFI in whom primary and/or secondary antifungal prophylaxis (AFP) should be considered despite scant evidence. Pediatric groups at risk for IFI includes extremely premature infants in some settings, while in high-risk children with cancer receiving chemotherapy or undergoing haematopoietic stem cell transplantation (HCT), AFP against yeast and moulds is usually recommended. For solid organ transplanted, children, prophylaxis depends on the type of transplant and associated risk factors. In children with primary or acquired immunodeficiency such as HIV or long-term immunosuppressive treatment, AFP depends on the type of immunodeficiency and the degree of immunosuppression. Chronic granulomatous disease is associated with a particular high-risk of IFI and anti-mould prophylaxis is always indicated. In contrast, AFP is not generally recommended in children with long stay in intensive care units. The choice of AFP is limited by the approval of antifungal agents in different age groups and by their pharmacokinetics characteristics. This document aims to review current available information on AFP in children and to provide a comprehensive proposal for each type of patient.

Current aspects in sepsis approach. Turning things around.

The incidence and prevalence of sepsis depend on the definitions and records that we use and we may be underestimating their impact. Up to 60% of the cases come from the community and in 30-60% we obtain microbiological information. Sometimes its presentation is ambiguous and there may be a delay in its detection, especially in the fragile population. Procalcitonin is the most validated biomarker for bacterial sepsis and the one that best discriminates the non-infectious cause. Presepsin and pro-adrenomedullin are useful for early diagnosis, risk stratification and prognosis in septic patients. The combination of biomarkers is even more useful to clarify an infectious cause than any isolated biomarker. Resuscitation with artificial colloids has worse results than crystalloids, especially in patients with renal insufficiency. The combination of saline solution and balanced crystalloids is associated with a better prognosis. Albumin is only recommended in patients who require a large volume of fluids. The modern molecular methods on the direct sample or the identification by MALDI-TOF on positive blood culture have helped to shorten the response times in diagnosis, to optimize the antibiotic treatment and to facilitate stewardship programs. The hemodynamic response in neonates and children is different from that in adults. In neonatal sepsis, persistent pulmonary hypertension leads to an increase in right ventricular afterload and heart failure with hepatomegaly. Hypotension, poor cardiac output with elevated systemic vascular resistance (cold shock) is often a terminal sign in septic shock. Developing ultra-fast Point-of-Care tests (less than 30 minutes), implementing technologies based on omics, big data or massive sequencing or restoring "healthy" microbiomes in critical patients after treatment are the main focuses of research in sepsis. The main benefits of establishing a sepsis code are to decrease the time to achieve diagnosis and treatment, improve organization, unify criteria, promote teamwork to achieve common goals, increase participation, motivation and satisfaction among team members, and reduce costs.

Relationship between bacterial load, morbidity and cagA gene in patients infected by Helicobacter pylori.

One hundred and seventy-six biopsies of the gastric corpus and antrum from 97 patients were processed using classical and molecular methods in order to study the relationship between the factor cagA of Helicobacter pylori, bacterial load and morbidity. Bacterial load in patients with cagA was greater than in patients without it, both in the antrum and corpus (p<0.01). There was a statistically significant association between cagA and consumption of proton pump inhibitors (adjusted odds ratio 3.11). Haemorrhage of the upper digestive tract was more associated with bacterial load than with the cagA gene (adjusted odds ratio 2.34 and 1.12, respectively), but none of these associations yielded statistical significance.

Síndrome compartimental tras bypass cardiopulmonar / Compartment syndrome after cardiopulmonary bypass

El síndrome compartimental de las extremidades inferiores es una complicación secundaria a isquemia y a daño por reperfusión. El diagnóstico y tratamiento precoces son esenciales para evitar la progresión de las lesiones. Se presenta una paciente con síndrome compartimental de la extremidad inferior izquierda tras la canalización de arteria y vena femorales izquierdas para la realización de bypass cardiopulmonar (AU)
