Recent research suggests that amyloid-beta proteins associated with Alzheimer disease can be transmitted via medical and surgical procedures person-to-person

This evidence presents the initial studies on Creutzfeldt-Jakob disease as a consequence of treatment with cadaver-derived human growth factor hormone.  Post-mortem brain tissue revealed that patients had developed cerebral amyloid deposition in addition to the lesions due to mad cow disease. Clearly, those individuals will never […]

Antibiotic management of urinary tract infections in elderly patients ( 65 years and more) in primary care and its association with bloodstream infections and all cause mortaliy: population based cohort study

This is a big data study including 157,264 patients with 312,896 urinary tract infections episodes. Of these patients, 7.2 % did not have antibiotics being prescribed and 6.2 % a delay in antibiotic prescribing. 1,539 bloodstream infections deriving from UTI were registered (0.5 %) within […]

A therapeutic strategy for all pneumonia patients: a 3-year prospective multicenter cohort study using risk factors for multiresistant pathogens to select initial empiric therapy

Pneumonia empiric therapy is currently based on the site of acquisition (community or hospital), but could be chosen, based on risk factors for multiresistant (MDR) pathogens. The authors applied an algorithm to 1,089 patients using MDR risks (antibiotic use on the last 180 days before […]

Inhaled liposomal ciprofloxacin in patients with noncystic fibrosis bronchiectasis and chronic lung infection with Pseudomonas aeruginosa ( orbit-3 e orbit-4): tow phase 3, randomized controlled trials

Patients with non-cystic fibrosis bronchiectasis and lung infection due to Pseudomonas aeruginosa experience frequent infection exacerbations, decreased in quality of life, and increased in mortality. Orbit-3 and ORBIT-4 were randomized double blind, placebo controlled trials that applied liposomal ciprofloxacin or placebo inhalation to their study […]

Strain-specific antibody therapy prevents cytomegalovirus reactivation after transplantation

Cytomegalovirus infection and its reactivation is frequent after solid organs and hematopoietic stem cell transplantation, and this infection can cause significant impact on transplantation outcomes. In mouse experimental models and in hematopoietic stem cells, an infusion in the presence of strain-specific anti-cytomegolovirus, was protective. There […]

We need to develop new antibiotics

Progressing of antibiotic resistance in bacteria erodes our therapeutic resources. Some infections are caused by bacteria that have only one or no therapeutic options. New antibacterial agents should be developed, but economic considerations conspire against investing in this market. Antibiotics are used, at most, two […]

HIV viral load and transmissibility of HIV infection: undetectable means non transmissible

Many evidences exist on undetectable HIV viral load – which means less than 200 genomic copies/ml signifies that a patient will not transmit infection to other person. This small. but powerful review article, insists that all persons with HIV should adhere to treatment and have […]

Change from intravenous to oral antibiotics is possible, even in cases of endocarditis or bone and joint infections

A study from Denmark by Iversen and colleagues that included 400 patients with left side endocarditis compared two groups. Their sample was composed by randomized patients who used the usual regimen of intravenous antibiotics for longer periods versus those who changed intravenous antibiotics to oral […]

Acute infection and myocardial infarction

The risk of myocardial infarction after infection is well known, and for inpatients with pneumococcal pneumonia, it is 7 to 8%. This risk is higher at the onset of infection, is proportional to severity of pneumonia, and persists for at least 5 weeks. The risk […]

Hard to treat multi-resistant gram negative bacteremia

First line antibiotics for gram negative bacteremia were defined as simultaneous to all carbapenems, all other beta lactams and all fluoroquinolones. In a sample including 173 American hospitals and 45,011 patients with gram negative bacteremia, a total of 471 (1%) had what the authors called difficult-to-treat […]
