RESUMEN
BACKGROUND: Multiple sclerosis is an inflammatory and neurodegenerative disease. People with multiple sclerosis (pwMS) experience chronic fatigue which is difficult to deal with therapeutically and greatly affects health-related quality of life (QOL). PwMS are aware of the lack of generalized dietary advice related to their disease, leading to self-experimentation with diet. It is necessary to provide objective information about dietary interventions for pwMS. We aim to provide an objective synthesis of the evidence for efficacy and safety of specific diets in pwMS through a rapid review and meta-analyses of randomized controlled trials (RCTs), examining symptomatic fatigue (MFIS), QOL, Expanded-Disability-Status-Scale (EDSS), and severe adverse events. METHODS: We have carried out a rapid review (MEDLINE and EMBASE) up to December 2021, with PRISMA methodology, and meta-analyses, of (RCTs). All statistical analyses were performed using the comprehensive meta-analysis (CMA) -RStudio 4.1.3. The analysis used weighted mean differences (WMD) and a 95% confidence interval (CI) using a random-effects model to compare the effects of the dietary intervention with the control. RESULTS: Eight studies met the inclusion criteria. Of these eight studies, five analyzed EDSS, three MFIS, and three QOL. A total of 515 patients were analyzed. These meta-analyses cumulative evidence support that dietary intervention is associated with a trend of reduction in fatigue (308 patients studied) -the difference between means (SMD) of the control group and intervention group was -2,033, 95%-IC (-3,195, -0,152), a p-value of 0.0341)-, an increase in QOL (77 patients studied), no significant effect on EDSS (337 patients studied), and no severe adverse events. CONCLUSIONS: It is difficult to reach a high level of evidence in dietary studies. Our findings show that dietary intervention is associated with a trend of reduction in fatigue in MS. Taking into account the potential of dietary interventions and the benefit/risk ratio in their favor, neurologists must be aware of the great importance of making interventions on diet in MS if necessary. There are dietary interventions with some evidence of benefit for patients with MS, which could be chosen based on adherence, patient preferences, and individual outcomes. Large prospective clinical trials are needed to shed further light on this topic.

Antibiotic stewardship programs (ASP) have already demonstrated clinical benefits. We aimed to describe the Point Prevalence Surveys (PPS) methodology implemented in our hospital as an efficient tool to guide ASP strategies. Annually repeated PPS were conducted from 2012 to 2019 at a 750-bed university hospital in South Spain. Key quality indicators and inappropriateness of antimicrobial treatment, defined strictly according to local guidelines, were described. Variables associated with inappropriate treatment were identified by bi/multivariable analysis. A total of 1,600 patients were included. We found that 49% of the prescriptions were inappropriate due to unnecessary treatment (14%), not first line drug recommended (14%), inadequate drug according to microbiological results (9%), unsuitable doses (8%), route (3%) or duration (7%). Samples collection presented a significant protective effect together with sepsis presentation at onset and intensive care unit admission. However, age, receiving an empirical treatment and an unknown or urinary source of the infections treated were independent risk factors for inappropriateness. Site and severity of infection were documented in medical charts by prescribers (75 and 61% respectively). PPS may allow identifying the main risk factors for inappropriateness. This simple methodology may be useful for ASP to select modifiable factors to be prioritized for targeted interventions.
RESUMEN
BACKGROUND: There is lack of information on the efficacy and safety of piperacillintazobactam administered by continuous infusion. OBJECTIVE: The aim of this study was to investigate whether continuous infusion of piperacillintazobactam is superior in terms of efficacy to a 30 % higher dose administered by intermittent infusion to treat suspected or confirmed infection due to Pseudomonas aeruginosa. Setting Multicenter clinical trial with 11 third level Spanish hospitals. METHOD: Randomized, double-blind parallel-group clinical trial, controlled by conventional administration of the drug. Patients randomly assigned in a 1:1 ratio to receive piperacillintazobactam as continuous infusion (CI) or intermittent (II). MAIN OUTCOME MEASURE: Primary efficacy endpoint was percentage of patients having a satisfactory clinical response at completion of treatment, defined as clinical cure or clinical improvement. Adverse events were reported. Results 78 patients were included, 40 in the CI group and 38 in the II group. Mean (standard deviation) duration of treatment was 7 (±4.44) days. 58 patients (74.4 %) experienced cure or improvement at the end of the treatment. There were no statistical differences in cure rates between the two treatment arms and no adverse events were reported. CONCLUSION: Continuous infusion of piperacillintazobactam is an alternative administration drug method at least similar in efficacy and safety to conventional intermittent infusion. Multivariate analysis is needed to determine whether continuous administration might be more beneficial than intermittent in certain patient subgroups.
