Psychoeducational Intervention for Reducing Heart Failure Patients' Rehospitalizations and Promoting Their Quality of Life and Posttraumatic Growth at the 1-Year Follow-Up: A Randomized Clinical Trial.

OBJECTIVE: This study's aim was to verify whether a psychoeducational intervention, with a brief expressive posttraumatic growth (PTG) component, could reduce heart failure (HF) patients' hospital readmissions and promote their quality of life (QoL) and PTG. METHODS: It adopted a parallel randomized clinical trial design, and its participants comprised HF patients from a hospital in Southern Brazil. All the participants completed the World Health Organization Quality of Life Assessment and Posttraumatic Growth Inventory questionnaires at the pre (T1: baseline) and post (T2) assessments of the intervention. Although patients in the control group (CG) underwent only regular outpatient consultations, those in the intervention group (IG) supplemented their regular consultations, with two additional individual visits to promote health and psychological education. At the 1-year follow-up, hospital readmissions were assessed. RESULTS: Of the 142 patients recruited at baseline (72 and 70 in the CG and IG, respectively), as 19 dropped out at follow-up, only 123 (63 and 60 in the CG and IG, respectively) were reassessed after approximately 378 days. They included 65% men aged 64 (11) years, 58% had low incomes, and 67% had less than high school education. The IG participants' risk of readmission got reduced by 52% ( p = .023), and they also showed significant improvements in their total QoL and positive psychological growth at the 6-month follow-up assessment. CONCLUSIONS: The two-session psychoeducational intervention proved to be protective for Southern Brazilian HF patients in the IG, as it effectively reduced their hospital readmission rates by half compared with the CG, as well as improved their QoL and promoted their positive psychological growth.

Bilateral deep brain stimulation of the subthalamic nucleus: Targeting differences between the first and second side.

INTRODUCTION AND OBJECTIVES: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a recognized treatment for drug-refractory Parkinson's disease (PD). However, the therapeutic success depends on the accuracy of targeting. This study aimed to evaluate potential accuracy differences in the placement of the first and second electrodes implanted, by comparing chosen electrode trajectories, STN activity detected during microelectrode recording (MER), and the mismatch between the initially planned and final electrode positions on each side. MATERIALS AND METHODS: In this retrospective cohort study, we analyzed data from 30 patients who underwent one-stage bilateral DBS. For most patients, three arrays of microelectrodes were used to determine the physiological location of the STN. Final target location depended also on the results of intraoperative stimulation. The choice of central versus non-central channels was compared. The Euclidean vector deviation was calculated using the initially planned coordinates and the final position of the tip of the electrode according to a CT scan taken at least a month after the surgery. RESULTS: The central channel was chosen in 70% of cases on the first side and 40% of cases on the second side. The mean length of high-quality STN activity recorded in the central channel was longer on the first side than the second (3.07±1.85mm vs. 2.75±1.94mm), while in the anterior channel there were better MER recordings on the second side (1.59±2.07mm on the first side vs. 2.78±2.14mm on the second). Regarding the mismatch between planned versus final electrode position, electrodes on the first side were placed on average 0.178±0.917mm lateral, 0.126±1.10mm posterior and 1.48±1.64mm inferior to the planned target, while the electrodes placed on the second side were 0.251±1.08mm medial, 0.355±1.29mm anterior and 2.26±1.47mm inferior to the planned target. CONCLUSION: There was a tendency for the anterior trajectory to be chosen more frequently than the central on the second side. There was also a statistically significant deviation of the second electrodes in the anterior and inferior directions, when compared to the electrodes on the first side, suggesting that another cause other than brain shift may be responsible. We should therefore factor this during planning for the second implanted side. It might be useful to plan the second side more anteriorly, possibly reducing the number of MER trajectories tested and the duration of surgery.

Nosocomial sepsis: evaluation of the efficacy of preventive measures in a level-III neonatal intensive care unit.

OBJECTIVE: To evaluate nosocomial infections preventive bundle, implemented in April 2010 in Centro Hospitalar de São João (CHSJ) Neonatal Intensive Care Unit (NICU) effectiveness. METHODS: Newborns admitted to level-III NICU of CHSJ, between 1 April 2007 and 31 March 2013, with sepsis as discharge diagnosis, were selected and divided into two periods (Period 1 and 2, before and after new preventive bundle introduction). Data from the two periods were compared. RESULTS: Nosocomial sepsis incidence density decreased significantly from 8.6 to 4.8 per 1000 patient days from Period 1 to 2. Nosocomial infections preventive bundle implementation led to a significant decrease in central line-associated bloodstream infections (CLABSI) rates from 14.1 to 10.4 per 1000 catheter days. CONCLUSIONS: Nosocomial infections preventive bundle implemented revealed efficient in decreasing the incidence density of nosocomial sepsis. However, CLABSI rates remain high. Physicians should be alert to the need to adhere to strict infection control protocols and institute effective measures for nosocomial infection surveillance.
