RESUMEN
PURPOSE: The time toxicity of anticancer therapy, defined as days spent with healthcare contact during treatment, represents a critical but understudied outcome. This study aims to quantify time toxicity among older patients with cancer receiving palliative systemic treatment. METHODS: All patients aged ≥ 65 years with metastatic cancer receiving cytotoxic chemotherapy, immunotherapy, or targeted therapy at a single center in Mexico were selected from a prospective patient navigation cohort. Patients completed a baseline assessment, including the G8 screening and quality of life measures. Physical healthcare contact days within the first 6 months were extracted from medical records and divided by days alive during the same period. Beta regression models were used to identify predictors of time toxicity. RESULTS: We identified 158 older patients (median age 71 years); 86% received cytotoxic chemotherapy. Seventy-three percent had an impaired G8 score and were considered vulnerable/frail. Six-month overall survival was 74%. Within the first 6 months, patients spent a mean of 21% (95% confidence interval (CI) 19-23%) of days with healthcare contact. Concurrent radiotherapy (odds ratio (OR) 1.55; 95%CI 1.21-1.97), cytotoxic chemotherapy versus targeted therapy (OR 1.64; 95%CI 1.13-2.37), and an impaired G8 (OR 1.27; 95%CI 1.01-1.60) were associated with increased time toxicity. CONCLUSION: Older adults with metastatic cancer spend 1 in 5 days with healthcare contact during treatment, with a higher burden of time toxicity for patients receiving radiotherapy or cytotoxic chemotherapy and those with potential frailty. These findings underscore the importance of informing patients about their expected healthcare contact days within the context of a limited life expectancy.

OBJECTIVES: We sought to identify risk factors associated with vancomycin-resistant Enterococcus faecium (VRE) and ampicillin-resistant Enterococcus faecalis (ARE) bacteraemia, predictors of 30-day mortality, and 90-day recurrence-free survival according to resistance. METHODS: We evaluated clinical records of patients with E. faecalis and E. faecium bacteraemia (2007-2017). We performed bivariate and multivariate logistic regression analyses to identify factors associated with VRE and ARE bacteraemia and predictors of 30-day mortality. A Kaplan-Meier estimate of 90-day recurrence-free survival was done. RESULTS: We identified 192 and 147 E. faecium and E. faecalis bacteraemia episodes, respectively, of which 55.7% of E. faecium were VRE (94% vanA) and 12.2% of E. faecalis were ARE. Factors related to VRE bacteraemia were previous hospitalisation (aOR, 80.18, 95% CI 1.81-634), history of central venous catheter (aOR, 11.15, 95% CI 2.48-50.2) and endotracheal cannula use (aOR, 17.91, 95% CI 1.22-262.82). There was higher attributable mortality to VRE (28%, 95% CI 14-68%; P < 0.001) and ARE (10%, 95% CI 0.1-36%; P = 0.58) compared with their susceptible counterparts. APACHE II (aOR, 1.45, 95% CI 1.26-1.66) and history of chemotherapy (aOR, 3.52, 95% CI 1.09-11.39) were predictors of E. faecium bacteraemia 30-day mortality. We could not recognise any factor related to ARE bacteraemia or E. faecalis 30-day mortality. CONCLUSION: History of hospitalisation and invasive device use were related to VRE bacteraemia. APACHE II and history of chemotherapy were predictors of mortality. We could not identify factors related to ARE or predictors of mortality.

Aim: In this study, we conducted a comparative study to explore the differences in therapeutic efficacy and intestinal microbiome of fecal microbiota transplant (FMT) vs. FMT in addition with Lactobacillus (FMT-L) for treatment of recurrent Clostridioides difficile infection (R-CDI). Methods: We designed a double-blinded randomized comparative two-arm pilot multicenter study to assess the efficacy and impact in the intestinal microbiome of standard capsules of FMT vs. FMT-L enriched with 3 species of Lactobacillus for patients with R-CDI. A 90-day follow-up of 21 patients was performed, starting at the beginning of the study. From the selected patients, fecal samples were obtained at days 0, 3, 7, and 28 after treatment. Fecal samples and FMT were analyzed by 16S rRNA sequencing. Results: We included 21 patients (13 in the FMT group and 8 in the FMT-L group). Overall, both groups had a reduction in bowel movements per day, from 8.6 to 3.2 in the first 48 h (62.7% reduction, p=0.001). No severe adverse reactions or recurrences were recorded. Firmicutes were the most abundant phylum in donors. A low relative abundance of Proteobacteria was detected and mostly found in patients even at higher proportions than the donor. The donor's pool also had relatively few Bacteroidetes, and some patients showed a higher abundance of this phylum. Based on the ANOSIM R values, there is a significant difference between the microbial communities of basal samples and samples collected on day 7 (p=0.045) and at day 28 (0.041). Conclusion: Fecal microbiota transplant by capsules was clinically and genomically similar between traditional FMT and enriched FMT with Lactobacillus spp. Restoration of bacterial diversity and resolution of dysbiosis at days 7 and 28 were observed. Patients with a first episode of recurrence treated with FMT had an excellent response without severe adverse events; FMT should be considered as an early treatment during R-CDI.
