BACKGROUND Patients with cancer have several risk factors for developing respiratory failure requiring mechanical ventilation(MV).The emergence of multidrug resistant bacteria(MDRB)has become a public health problem,creating a new burden on medical care in hospitals,particularly for patients admitted to the intensive care unit(ICU).AIM To describe risk factors for ventilator-acquired pneumonia(VAP)in patients with cancer and to evaluate the impact of *** A retrospective study was performed from January 2016 to December 2018 at a cancer referral center in Mexico City,which included all patients who were admitted to the ICU and required MV≥48 *** were classified as those who developed VAP versus those who did not;pathogens isolated,including *** evolution at 60-d was *** analysis was carried out;comparison was performed between VAP vs non-VAP and MDRB vs *** Two hundred sixty-three patients were included in the study;mean age was 51.9 years;52.1%were male;68.4%had solid *** were 32 episodes of VAP with a rate of 12.2%;11.5 episodes/1000 *** most frequent bacteria isolated were the following:Klebsiella spp.[n=9,four were Extended-Spectrum Beta-Lactamase(ESBL)producers,one was Carbapenem-resistant(CR)];Escherichia coli(n=5,one was ESBL),and Pseudomonas aeruginosa(n=8,two were CR).One Methicillin-susceptible Staphylococcus aureus was *** multivariate analysis,the sole risk factor associated for VAP was length of ICU stay(OR=1.1;95%CI:1.03-1.17;P=0.003).Sixty-day mortality was 53%in VAP and 43%without VAP(P=0.342).There was not higher mortality in those patients with *** This study highlights the high percentage of Gram-negative bacteria,which allows the initiation of empiric antibiotic coverage for these *** this retrospective,single center,observational study,MDRB VAP was not directly linked to increased mortality at 60 days.

Pediatric chronic liver diseases encompass a wide spectrum of hepatopathies with a relevant health medical and financial burden(1,2).In addition to inherited disorders(e.g.,Alagille syndrome,metabolic disorders,etc.),there are numerous chronic liver conditions including metabolic dysfunction-associated steatotic liver disease(MASLD)and autoimmune liver diseases affecting morbidity,quality of life,and life expectancy of these young patients(3,4).To complicate matters,the exact prevalence of childhood chronic liver diseases is still unknown since their asymptomatic course especially in the early stages but increasing rates are reported worldwide(1,5,6).Moreover,management of these chronic conditions represents a great challenge for clinicians as it requires a lifelong multi-disciplinary approach(1).Worthy of note,advances in the knowledge of pathophysiological mechanisms underlying liver diseases greatly improved their natural history with increased survival rates into adulthood(1,3).Given that,adult hepatologists are increasingly dealing with most of these conditions(3).

Background In ambrosia and bark beetles–fungi interaction, volatile organic compounds(VOCs) play a central role in mediating various aspects of community dynamics of beetles and/or fungi. These functions include facilitating beetle habitat location, mate identification, and fungal partner differentiation. However, the understanding on this context remains limited, especially in the globally distributed subfamily Platypodinae, which comprises predomi-nantly ambrosia beetles. There is a lack of chemical data on ambrosia fungi from native South American species. This study addresses this gap by characterizing VOCs from twelve fungal species associated with Megaplatypus mutatus and assessing species-specific behavioral responses during *** Fungal VOCs were collected by gas chromatography–mass spectrometry combined with solid-phase microextraction and Y-olfactometry assays of males and females were performed at dispersal stage. Statistical analyses involved: non-metric multidimensional scaling multivariate plot and PERMANOVA test, a cluster analysis through unweighted pair group method with Jaccard index, and finally, a chi-square goodness-of-fit test for beetle behavioral *** We identified 72 VOCs from the fungal species isolated from M. mutatus galleries, exocuticle, and gut. The olfactory behavior of M. mutatus demonstrated its capacity to discriminate between volatile profiles, showing a pref-erence for either the fungus or the control source. Our results also enhance the understanding in a chemotaxonomic context and in the behavioral responses of M. mutatus revealing the beetle's remarkable low temperature toler-ance and its capability to maintain mobility and orientation toward volatile sources even after zero-degree Celsius *** This study presents a comprehensive insight into fungal VOC profiles, emphasizing the sources of isola-tion within pest associated fungi, as well as its symbiotic species from the Raffaelea genus.
