Comorbidity and Malnutrition as Key Determinants of Mortality in Elderly Haemodialysis Patients: A One-Year Observational Study
No full textBackground: In elderly haemodialysis patients, poor functional status correlates with malnutrition, morbidity and mortality. This study aimed to assess 1-year survival in an elderly haemodialysis population and evaluate the predictive capacity of commonly used scales for comorbidity, malnutrition, dependence and frailty.
Methods: We conducted a 1-year observational study (2022) on prevalent haemodialysis patients aged > 75 years with > 3 months of treatment. Mortality was assessed during the follow-up. We analysed sociodemographic, dialysis-related, analytical and lifestyle variables. Additionally, we evaluated comorbidity (Charlson), dependence (Barthel), malnutrition-inflammation (MIS scale) and frailty (FRIED). Statistical analysis included comparisons between continuous variables using the Mann-Whitney U test or Student's t test, based on normality distribution. Categorical variables were compared using the chi-square test. Kaplan-Meier survival analysis with log-rank test was used to compare survival curves. Multivariate analysis was performed using Cox proportional hazards models, adjusting for confounders including dialysis adequacy and underlying kidney disease aetiology. Optimal cutoff points for predicting mortality were determined using receiver operating characteristic (ROC) curves.
Results: A total of 107 haemodialysis patients (57% male, mean age 81.3 ± 4.53 years, mean time on haemodialysis 51.71 ± 51.04 months) were included. Sixteen patients (15%) died within 1 year. Deceased patients were older (83.94 ± 4.52 vs. 80.34 ± 4.39 years, p = 0.011) and had longer dialysis duration (76.46 ± 54.73 vs. 47.35 ± 49.4 months, p = 0.035), lower albumin (3.51 ± 0.54 vs. 3.86 ± 0.31 g/dL, p < 0.001) and lower creatinine levels (5.48 ± 1.12 vs. 6.50 ± 1.67 mg/dL, p = 0.021). They scored higher on all four scales analysed: Charlson (10.94 ± 1.81 vs. 8.95 ± 1.92, p < 0.001), MIS (11.31 ± 4.22 vs. 6.07 ± 3.27, p < 0.001), Barthel (52.50 ± 27.2 vs. 78.41 ± 23.11, p < 0.001), and FRIED (3.19 ± 1.05 vs. 2.18 ± 1.32, p = 0.005). Institutionalization (p = 0.004), inability to walk (p < 0.001) and stretcher transport (p < 0.001) were also significantly associated with mortality. The optimal cutoff points for predicting mortality were Charlson index ¿ 9.5 (AUC 0.788, 95% CI: 0.65-0.88), MIS ¿ 7.5 (AUC 0.844, 95% CI: 0.73-0.93), Barthel ¿ 67.5 (AUC 0.79, 95% CI: 0.68-0.79) and FRIED ¿ 2.5 (AUC 0.719, 95% CI: 0.56-0.83). In multivariable analysis, Charlson ¿ 9.5 (HR 2.75, 95% CI: 0.83-9.06, p = 0.096) and MIS ¿ 7.5 (HR 8.15, 95% CI: 1.10-60.58, p = 0.040) remained significant predictors of mortality.
Conclusions: The Charlson, Barthel, MIS and FRIED scales are useful tools for predicting mortality in elderly haemodialysis patients, with defined cutoff points for increased mortality risk. We have defined specific cutoff points that determine increased mortality risk in this population. However, comorbidity and malnutrition showed the strongest independent predictive value. These findings highlight the need for targeted interventions to address malnutrition and comorbidity in this vulnerable population.202

Antimicrobial activity of piperacillin/tazobactam against key peri-implant pathogens: an in vitro comparative study with amoxicillin-clavulanate and minocycline
No full textBackground: Peri-implantitis is an inflammatory disease linked to bacterial biofilms that threatens the long-term success of dental implants. The growing problem of antibiotic resistance among peri-implant pathogens highlights the need to explore alternative antimicrobial agents with proven in vitro efficacy.
Material and methods: This in vitro study evaluated the antimicrobial activity of piperacillin/tazobactam compared with two commonly used antibiotics in dentistry: amoxicillin-clavulanate and minocycline. The minimum inhibitory concentrations (MICs) were determined using Etest® gradient diffusion strips against three key peri-implant pathogens: Porphyromonas gingivalis, Prevotella intermedia, and Aggregatibacter actinomycetemcomitans. Cultures were incubated under anaerobic conditions to simulate the peri-implant environment.
Results: Piperacillin/tazobactam demonstrated MIC values comparable to those of amoxicillin-clavulanate and minocycline for P. gingivalis and A. actinomycetemcomitans, and lower MICs against P. intermedia. Statistical analysis confirmed that piperacillin/tazobactam is not inferior to these widely used antibiotics.
Conclusions: Piperacillin/tazobactam shows promising in vitro antimicrobial activity against key peri-implant pathogens and may serve as an effective alternative or adjunctive treatment in managing peri-implantitis. Further clinical studies are warranted to confirm its efficacy and safety in vivo.202
