One of the main pillars of acute ischemic stroke management is antiplatelet therapy. Different treatment schemes have been compared, suggesting that the combination of multiple antiplatelet drugs is associated with a reduced risk of stroke recurrence. However, it has also been associated with an increased risk of bleeding complications which, in the long term, surpass the mentioned benefits. ⋯ All trials comparing double versus single antiplatelet therapy in patients with acute ischemic stroke were included. Results showed that double therapy reduces recurrence risk but probably marginally increases major bleeding complications. We suggest double antiplatelet therapy for the initial management of patients with minor (Score NIH < or equal to 3 or transient isquemic attack -TIA) acute ischemic stroke.

The early identification of patients with palliative needs has shown benefits in terms of quality of life and treatment goals. No prospective methods have been applied in Argentina to identify palliative needs in cancer patients. The NECPAL tool combines the physician's own insight with objective indicators of disease progression and indicators of chronic advanced conditions. ⋯ In the multivariate model, the best predictors of mortality combining relevant indicators were: inpatients (HR 1.87; 95% CI 1.24-2.84; p = 0.003), initial diagnosis other than breast cancer (HR 2.04; 95% CI 1.23-3.40; p = 0.006), metastatic disease (HR 1.67; 95% CI 1.15-2.42; p = 0.007), functional deterioration (HR 1.95; 95% CI 1.28-2.97; p = 0.002), and malnutrition (HR 1.53; 95% CI 1.04-2.23; p = 0.02 9). The major breakthrough was the systematic prospective identification of palliative needs in cancer patients for the first time in Argentina. The NECPAL tool can improve the prediction of mortality in hospital settings.

Locally advanced pancreatic cancer (LAPC) has several definitions, but it is essentially a non-metastatic tumor, in which the initial surgical resection is not considered beneficial due to the extensive vascular involvement and consequent high chance of a nonradical resection. The introduction of chemotherapy with calcium leucovorin, fluorouracil, irinotecan hydrochloride and oxaliplatin (FOLFIRINOX) and gemcitabine-nab (nanoparticle albumin-bound)-paclitaxel (gem-nab) had very important implications for the management of patients with LAPC. After 4 to 6 months of induction chemotherapy, a large proportion of them have stable disease or even tumor regression, allowing to rescue those who initially were not candidates for surgery, with 30-35 months overall survival after surgery.

Cardiovascular disease (CVD) is the leading cause of death in Argentina. Computer simulation models allow to extrapolate evidence to broader populations than the originally studied, over longer timeframes, and to compare different subpopulations. The Cardiovascular Disease Policy Model (CVDPM) is a computer simulation state transition model used to represent and project future CVD mortality and morbidity in the population 35 years-old and older. ⋯ Country statistics for people 35 years-old and older reported for 2010 a total of 41 219 myocardial infarctions (MIs), 58 658 strokes, and 281 710 total deaths. The CVDPM, in turn, predicted 41 265 MIs (difference: 0.11%), 58 584 strokes (difference: 0.13%), and 280 707 total deaths (difference: 0.36%) in the same population. In all cases, the final version of the model predicted the actual number of events with an accuracy superior to 99.5%, and could be used to forecast the changes in CVD incidence and mortality after the implementation of public policies.

Case Reports
[Refractory colitis by Clostridium difficile treated with fecal microbiota transplant].
Clostridium difficile infection is an increasingly recognized cause of diarrhea in inpatients, frequently associated to high mortality. Vancomycin is the treatment of choice for all Clostridium difficile- associated diarrheas, with different degrees of severity. ⋯ Fecal microbiota transplantation has been shown to be successful in a series of cases of severe diarrhea associated with this organism. We present a case of refractory C. difficile infection successfully treated with fecal microbiota transplantation.
