Effects of hammock positioning in behavioral status,vital signs,and pain in preterms: a case series study

Background

The hammock positioning within the incubators simulates the intrauterine environment, however, there is little evidence of its benefits and possible risks.

Survival and mortality among users and non-users of hydroxyurea with sickle cell disease

OBJECTIVE:

to estimate survival, mortality and cause of death among users or not of hydroxyurea with sickle cell disease.

METHOD:

cohort study with retrospective data collection, from 1980 to 2010 of patients receiving inpatient treatment in two Brazilian public hospitals. The survival probability was determined using the Kaplan-Meier estimator, survival calculations (SPSS version 10.0), comparison between survival curves, using the log rank method. The level of significance was p=0.05.

RESULTS:

of 63 patients, 87% had sickle cell anemia, with 39 using hydroxyurea, with a mean time of use of the drug of 20.0±10.0 years and a mean dose of 17.37±5.4 to 20.94±7.2 mg/kg/day, raising the fetal hemoglobin. In the comparison between those using hydroxyurea and those not, the survival curve was greater among the users (p=0.014). A total of 10 deaths occurred, with a mean age of 28.1 years old, and with Acute Respiratory Failure as the main cause.

CONCLUSION:

the survival curve is greater among the users of hydroxyurea. The results indicate the importance of the nurse incorporating therapeutic advances of hydroxyurea in her care actions.     

Non-vitamin K antagonist oral anticoagulation versus left atrial appendage occlusion for primary and secondary stroke prevention after cardioembolic stroke

IntroductionThis study aimed to evaluate the performance of non-vitamin K antagonist oral anticoagulation (NOAC) in patients with previous stroke and non-valvular atrial fibrillation (AF) compared with left atrial appendage occlusion (LAAO) in primary and secondary stroke prevention settings.MethodsThis was a prospective, single-center, non-randomized cohort study of 302 consecutive patients with non-valvular AF and at high risk for stroke. Two treatment strategies were compared: LAAO (n=91) and long-term treatment with NOAC (n=149). The primary outcome was the composite endpoint of death, stroke and major bleeding. Propensity score and cause-of-death analyses were performed to compare outcomes.ResultsIn a mean follow-up of 13 months, there were 30 deaths (LAAO 8.8% vs. NOAC 14.8%), five strokes (LAAO 1.1% vs. NOAC 2.7%) and six major bleeds (LAAO 1.1% vs. NOAC 3.4%). There was a non-significant trend for a lower incidence of the primary endpoint in the LAAO group (11.0% vs. 20.9%; HR 0.42, 95% CI 0.17-1.05, p=0.064). Considering only secondary prevention LAAO patients (34.1% of the LAAO group), there was also a non-significant lower incidence of the primary endpoint (LAAO 6.5% vs. 20.9%; HR 0.30, 95% CI 0.07-1.39, p=0.12). While about a fifth of LAAO patients stopped antiplatelet treatment six months after device implantation due to recurrent minor bleeding, no adverse cardiovascular event or major bleeding occurred in this subset of patients.ConclusionIn this registry-based study, LAAO was a reasonable alternative to NOAC for the prevention of a composite endpoint of all-cause mortality, stroke and major bleeding in patients at high risk for stroke.     

Brucella endocarditis in a non-endemic country: first reported case in East Asia.

Human brucellosis is a rare zoonosis in East Asia. A case of brucella endocarditis in a 59-year-old farmer who had mild rheumatic mitral stenosis is presented. Excision of the mitral valve with associated vegetation was performed and a mechanical valve was substituted. Antibiotic treatment with doxycycline, rifampicin, and trimethoprim/sulfamethoxazole was continued for 6 months. After 18 months of follow-up, the patient had no symptoms and no signs of relapse.     

Changes in the isoenzyme and kinetoplast DNA patterns of Trypanosoma cruzi strains induced by maintenance in mice

Culture forms of thirteen Trypanosoma cruzi strains from 4 zymodemes and 9 schizodemes were inoculated and kept by successive passages in C3H mice. The strains were initially from the following zymodemes: 3 from A, 3 from B, 4 from C and 2 from D and 1 from AB mixed zymodemes. After approximately 18 months maintenance the parasites were isolated by hemoculture and again typed according to their isoenzyme and kinetoplast DNA patterns. The zymodeme A strains kept their initial patterns; from the 3 zymodeme B strains, two kept the initial patterns and one changed to zymodeme A; from the 4 zymodeme C, two kept the initial pattern and two changed to zymodeme B; from the 2 zymodeme D strains, one kept the initial pattern and one changed to zymodeme A. The strain from AB mixed zymodeme was reduced to zymodeme. A. The zymodeme changes were accompanied by schizodeme changes. Although not simultaneously, in one T. cruzi strain the parasitemia change was followed by zymodeme and schizodeme changes. The results showed that prolonged maintenance of T. cruzi in mice by successive passages alters the isoenzyme and k-DNA patterns of some strains and that these alterations tend to move towards zymodeme A, suggesting a selective effect of mice over these T. cruzi populations.
