Our results suggest that fluoroquinolones are a risk factor for MRSA acquisition. Control measures to limit MRSA spread in LTCFs should also be based on optimization of fluoroquinolone use.
Uremic acidosis was well corrected without risk of alkalosis. An unexpected result was the continuous decay of bicarbonate dialysance both in HD and HDF during runs.
Setting
Drug resistance threatens tuberculosis (TB) control, particularly among HIV-infected persons.
Objective
We surveyed antiretroviral therapy (ART) programs from lower-income countries on prevention and management of drug-resistant TB.
Design
We used online questionnaires to collect program-level data in 47 ART programs in Southern Africa (14), East Africa (8), West Africa (7), Central Africa (5), Latin America (7) and Asia-Pacific (6 programs) in 2012. Patient-level data were collected on 1,002 adult TB patients seen at 40 of the participating ART programs.
Results
Phenotypic drug susceptibility testing was available at 36 (77%) ART programs, but only used for 22% of all TB patients. Molecular drug resistance testing was available at 33 (70%) programs and used for 23% of all TB patients. Twenty ART programs (43%) provided directly observed therapy (DOT) during the whole treatment, 16 (34%) during intensive phase only and 11 (23%) did not follow DOT. Fourteen (30%) ART programs reported no access to second-line TB regimens; 18 (38%) reported TB drug shortages.
Conclusions
Capacity to diagnose and treat drug-resistant TB was limited across ART programs in lower income countries. DOT was not always implemented and drug supply was regularly interrupted, which may contribute to the global emergence of drug resistance.
Introduction: In order to definitively integrate cryosurgery for the surgical treatment of atrial fibrillation (AF) into the therapeutic armamentarium, the medical and economic impact of its use on a population of patients with a high risk of recurrence of postoperative AF must be evaluated. Method: An observational study of patients who benefited from cryosurgery between July 2006 and December 2008 was performed. The cost of consumables and hospitalization was determined and compared to that of a control group of 27 patients with preoperative AF that had not benefited from cryosurgery. Results: Twenty-nine patients benefited from cryosurgery during a mitral (65.5%) or aortic intervention (37.9%) to treat a paroxystic (44.8%) or permanent AF (55.2%). More than half of them (58.6%) had a 12-month follow-up; 82.4% of these patients showed a permanent sinus rhythm and 32.6% had stopped their antiarrhythmic medication. There was no significant difference between the duration and cost of hospitalization for the 2 groups. Conclusion: Cryosurgery provides a clear clinical and economic advantage with no recurrence of AF, and it reduces antiarrhythmic medication treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
