Feasibility of non-invasive pressure support ventilation in infants with respiratory failure after extubation: a pilot study.

OBJECTIVE: To evaluate the feasibility and effects of non-invasive pressure support ventilation (NIV) on the breathing pattern in infants developing respiratory failure after extubation. DESIGN: Prospective pilot clinical study; each patient served as their own control. SETTING: A nine-bed paediatric intensive care unit of a tertiary university hospital. PATIENTS: Six patients (median age 5 months, range 0.5-7 months; median weight 4.2 kg, range 3.8-5.1 kg) who developed respiratory failure after extubation. INTERVENTIONS: After a period of spontaneous breathing (SB), children who developed respiratory failure were treated with NIV. MEASUREMENTS AND RESULTS: Measurements included clinical dyspnoea score (DS), blood gases and oesophageal pressure recordings, which were analysed for respiratory rate (RR), oesophageal inspiratory pressure swing (dPes) and oesophageal pressure-time product (PTPes). All data were collected during both periods (SB and NIV). When comparing NIV with SB, DS was reduced by 44% (P < 0.001), RR by 32% (P < 0.001), dPes by 45% (P < 0.01) and PTPes by 57% (P < 0.001). A non-significant trend for decrease in PaCO(2) was observed. CONCLUSION: In these infants, non-invasive pressure support ventilation with turbine flow generator induced a reduction of breathing frequency, dPes and PTPes, indicating reduced load of the inspiratory muscles. NIV can be used with some benefits in infants with respiratory failure after extubation.

Pulse pressure variation-guided fluid therapy after cardiac surgery: A pilot before-and-after trial.

PURPOSE: The aim of this study is to study the feasibility, safety, and physiological effects of pulse pressure variation (PPV)-guided fluid therapy in patients after cardiac surgery. MATERIALS AND METHODS: We conducted a pilot prospective before-and-after study during mandatory ventilation after cardiac surgery in a tertiary intensive care unit. We introduced a protocol to deliver a fluid bolus for a PPV ≥13% for at least >10 minutes during the intervention period. RESULTS: We studied 45 control patients and 53 intervention patients. During the intervention period, clinicians administered a fluid bolus on 79% of the defined PPV trigger episodes. Median total fluid intake was similar between 2 groups during mandatory ventilation (1297 mL [interquartile range 549-1968] vs 1481 mL [807-2563]; P = .17) and the first 24 hours (3046 mL [interquartile range 2317-3982] vs 3017 mL [2192-4028]; P = .73). After adjusting for several baseline factors, PPV-guided fluid management significantly increased fluid intake during mandatory ventilation (P = .004) but not during the first 24 hours (P = .47). Pulse pressure variation-guided fluid therapy, however, did not significantly affect hemodynamic, renal, and metabolic variables. No serious adverse events were noted. CONCLUSIONS: Pulse pressure variation-guided fluid management was feasible and safe during mandatory ventilation after cardiac surgery. However, its advantages may be clinically small.

The switch from conventional to atypical antipsychotic treatment should not be based exclusively on the presence of cognitive deficits. A pilot study in individuals with schizophrenia.

Background: Atypical antipsychotics provide better control of the negative and affective symptoms of schizophrenia when compared with conventional neuroleptics; nevertheless, their heightened ability to improve cognitive dysfunction remains a matter of debate. This study aimed to examine the changes in cognition associated with long-term antipsychotic treatment and to evaluate the effect of the type of antipsychotic (conventional versus novel antipsychotic drugs) on cognitive performance over time. Methods: In this naturalistic study, we used a comprehensive neuropsychological battery of tests to assess a sample of schizophrenia patients taking either conventional (n = 13) or novel antipsychotics (n = 26) at baseline and at two years after. Results: Continuous antipsychotic treatment regardless of class was associated with improvement on verbal fluency, executive functions, and visual and verbal memory. Patients taking atypical antipsychotics did not show greater cognitive enhancement over two years than patients taking conventional antipsychotics. Conclusions Although long-term antipsychotic treatment slightly improved cognitive function, the switch from conventional to atypical antipsychotic treatment should not be based exclusively on the presence of these cognitive deficits.

Mineralocorticoid Receptor Antagonism in the Treatment of Chronic Central Serous Chorioretinopathy : A Pilot Study.

PURPOSE:: Based on experimental data showing that central serous chorioretinopathy could result from overactivation of mineralocorticoid receptor pathway in choroid vessels, the authors studied eplerenone, a mineralocorticoid receptor antagonist, as a potential treatment for chronic central serous chorioretinopathy. METHODS:: This nonrandomized pilot study included 13 patients with central serous chorioretinopathy of at least 4-month duration, treated with 25 mg/day of oral eplerenone for a week followed by 50 mg/day for 1 or 3 months. The primary outcome measure was the changes in central macular thickness recorded by optical coherence tomography, and the secondary outcomes included changes in foveal subretinal fluid (SRF) measured by OCT, in best-corrected visual acuity (BCVA) and the percentage of eyes achieving complete resolution of subretinal fluid during the treatment period. RESULTS:: Central macular thickness decreased significantly from 352 ± 139 μm at baseline to 246 ± 113 μm and 189 ± 99 μm at 1 and 3 months under eplerenone treatment (P < 0.05 and P < 0.01, respectively). At 3 months, the subretinal fluid significantly decreased compared with baseline subretinal fluid (P < 0.01) and best-corrected visual acuity significantly improved compared with baseline best-corrected visual acuity (P < 0.001). CONCLUSION:: Eplerenone treatment was associated with a significant reduction in central macular thickness, subretinal fluid level, and an improvement in visual acuity. Randomized controlled trials are needed to confirm these encouraging results.

Citizens' preferences for brand name drugs for treating acute and chronic conditions: a pilot study.

Background: Generic drugs have been advocated to decrease the proportion of healthcare costs devoted to drugs, but are still underused. Objective: To assess citizens' preferences for brand name drugs (BNDs) compared with generic drugs for treating acute and chronic conditions. Methods: A questionnaire with eight hypothetical scenarios describing four acute and four chronic conditions was developed, with willingness to pay (WTP) determined using a payment card system randomized to ascending (AO) or descending order (DO) of prices. The questionnaire was distributed with an explanation sheet, an informed consent form and a pre-stamped envelope over a period of 3 weeks in 19 community pharmacies in Lausanne, Switzerland. The questionnaire was distributed to every third customer who also had health insurance, understood French and was aged =16 years (up to a maximum of ten customers per day and 100 per pharmacy). The main outcome measure was preferences assessed by WTP for BNDs as compared with generics, and impact of participants' characteristics on WTP. Results: Of the 1800 questionnaires, 991 were distributed and 393 returned (pharmacy participation rate?=?55%, subject participation rate?=?40%, overall response rate?=?22%); 51.7% were AO and 48.3% DO. Participants were predominantly women (62.6%) and of median age 62 years (range 16-90). The majority (70%) declared no WTP for BNDs as compared with generics. WTP was higher in people with an acute disease than in those with a chronic disease, did not depend on the type of chronic disease, and was higher in people from countries other than Switzerland. Conclusions: Most citizens visiting pharmacies attribute no added value to BNDs as compared with generics, although some citizen characteristics affected WTP. These results could be of interest to several categories of decision makers within the healthcare system.

Evaluating in vivo delivery of riboflavin with coulomb-controlled iontophoresis for corneal collagen cross-linking: a pilot study.

PURPOSE: To evaluate the efficacy of coulomb-controlled iontophoresis (CCI) for delivery of riboflavin prior to corneal collagen cross-linking (CXL). METHODS: The eyes of 20 8-week-old Lewis rats, subject to epithelium-ON (epi-ON, n = 20 eyes) or epithelium-OFF (epi-OFF, n = 20 eyes) conditions, were used to evaluate the in vivo delivery of two riboflavin solutions: 0.1% riboflavin-20% dextran T500 solution (riboflavin-dextran) and 0.1% riboflavin 5'-phosphate (riboflavin-phosphate). After systemic intramuscular anesthesia, 0.25 mL of the photosensitizing agent was delivered by either instillation or CCI (2.11 mA/cm(2) for 4 or 10 minutes) into either epithelial condition. The CCI probe on the eye without current served as control. Confocal microscopy of flat-mounted corneas was used to analyze intracorneal penetration and fluorometry was used to quantify riboflavin in the aqueous within 30 minutes of treatment. RESULTS: Instillation and CCI allowed for uniform delivery of riboflavin-dextran throughout the stroma after epithelial debridement. Transepithelial delivery of riboflavin-dextran was not efficacious. Riboflavin-phosphate was successfully delivered in both epithelium conditions. Complete saturation of the cornea was achieved using CCI after removing the epithelium, the epi-ON case allowed for limited diffusion. Increasing the time from 4 to 10 minutes greatly increased the amount of riboflavin detected in the cornea and aqueous humor. CONCLUSIONS: Coulomb-controlled iontophoresis is an effective technique for transepithelial delivery of riboflavin-phosphate into the cornea. This drug delivery method would allow clinicians to significantly shorten the time required for the CXL procedure, with or without epithelial debridement. Whether efficient crosslinking can be achieved through an intact epithelium remains to be demonstrated.

Juvenile Crime Prevention Community Grand Fund Outcomes Report and FY2002 Juvenile Justice Youth Development Program Summary, January 2002

This document contains two related, but separate reports. The Juvenile Crime Prevention Community Grant Fund Outcomes Report is a summary of outcomes from services and activities funded through the Juvenile Crime Prevention Community Grant Fund in FY2001. The Juvenile Justice Youth Development Program Summary describes Iowa communities’ current prevention and sanction programs supported with funding from the Division of Criminal and Juvenile Justice Planning (CJJP) during FY2002. The material in Juvenile Crime Prevention Community Grant Fund Outcomes Report is presented in response to a legislative mandate to report specific prevention outcomes for the community Grant Fund. It includes a brief description of a Youth Development Results Framework established by the Iowa Collaboration for Youth Development. Outcomes are reported using this results framework, which was developed by a number of state agencies as a common tool for various state programs involving youth development related planning and funding processes. Included in this report is a description of outcomes from the prevention activities funded, all or in part, by the Community Grant Fund, as reported by local communities. The program summaries presented in the Juvenile Justice Youth Development Program Summary provide an overview of local efforts to implement their 2002 Juvenile Justice Youth Development plans and include prevention and sanction programs funded through the combined resources of the State Community Grant Fund and the Federal Title V Prevention, Juvenile Justice & Delinquency Prevention Act Formula Grant and Juvenile Accountability Incentive Block Grant programs. These combined funds are referred to in this document as the Juvenile Justice Youth Development (JJYD) funds. To administer the JJYD funds, including funds from the Community Grant Fund, CJJP partners with local officials to facilitate a community planning process that determines the communities’ priorities for the use of the funds. The local planning is coordinated by the Iowa’s Decategorization Boards (Decats). These local officials and/or their staff have been leaders in providing oversight or staff support to a variety of local planning initiatives (e.g. child welfare, Comprehensive Strategy Pilot Projects, Empowerment, other) and bring child welfare and community planning experience to the table for the creation of comprehensive community longterm planning efforts. The allocation of these combined funds and the technical assistance received by the Decats from CJJP is believed to have helped enhance both child welfare and juvenile justice efforts locally and has provided for the recognition and establishment of connections for joint child welfare/juvenile justice planning. The allocation and local planning approach has allowed funding from CJJP to be “blended” or “braided” with other local, state, and federal dollars that flow to communities as a result of their local planning responsibilities. The program descriptions provided in this document reflect services and activities supported with JJYD funds. In many cases, however, additional funding sources have been used to fully fund the programs. Most of the information in this document’s two reports was submitted to CJJP by the communities through an on- line planning and reporting process established jointly by the DHS and CJJP.

Cytochrome P450 and ABCB1 genetics: association with quetiapine and norquetiapine plasma and cerebrospinal fluid concentrations and with clinical response in patients suffering from schizophrenia. A pilot study.

Variability in response to atypical antipsychotic drugs is due to genetic and environmental factors. Cytochrome P450 (CYP) isoforms are implicated in the metabolism of drugs, while the P-glycoprotein transporter (P-gp), encoded by the ABCB1 gene, may influence both the blood and brain drug concentrations. This study aimed to identify the possible associations of CYP and ABCB1 genetic polymorphisms with quetiapine and norquetiapine plasma and cerebrospinal fluid (CSF) concentrations and with response to treatment. Twenty-two patients with schizophrenia receiving 600 mg of quetiapine daily were genotyped for four CYP isoforms and ABCB1 polymorphisms. Quetiapine and norquetiapine peak plasma and CSF concentrations were measured after 4 weeks of treatment. Stepwise multiple regression analysis revealed that ABCB1 3435C > T (rs1045642), 2677G > T (rs2032582) and 1236C > T (rs1128503) polymorphisms predicted plasma quetiapine concentrations, explaining 41% of the variability (p = 0.001). Furthermore, the ABCB1 polymorphisms predicted 48% (p = 0.024) of the variability of the Δ PANSS total score, with the non-carriers of the 3435TT showing higher changes in the score. These results suggest that ABCB1 genetic polymorphisms may be a predictive marker of quetiapine treatment in schizophrenia.

Early mobilization out of bed after ischaemic stroke reduces severe complications but not cerebral blood flow: a randomized controlled pilot trial.

OBJECTIVE: To evaluate whether early mobilization after acute ischaemic stroke is better than delayed mobilization with regard to medical complications and if it is safe in relation to neurological function and cerebral blood flow. DESIGN: Randomized controlled pilot trial of early versus delayed mobilization out of bed with incidence of severe complications as the primary outcome. SETTING: Acute stroke unit in the neurology department of a University Hospital. PARTICIPANTS: Fifty patients after ischaemic stroke with a National Institutes of Health Stroke Scale (NIHSS) score >6 were recruited. INTERVENTION: All patients were treated with physiotherapy immediately after their admission. In the early protocol patients were mobilized out of bed after 52 hours, in the delayed protocol after seven days. RESULTS: Eight out of 50 randomized patients were excluded from the per-protocol analysis because of early transfer to other hospitals. There were 2 (8%) severe complications in the 25 early mobilization patients and 8 (47%) in the 17 delayed mobilization patients (P < 0.006). There were no differences in the total number of complications or in clinical outcome. In the 26 patients (62%) who underwent serial transcranial Doppler ultrasonography, no blood flow differences were found. CONCLUSION: We found an apparent reduction in severe complications and no increase in total complications with an early mobilization protocol after acute ischaemic stroke. No influence on neurological three-month outcomes or on cerebral blood flow was seen. These results justify larger trials comparing mobilization protocols with possibly even faster mobilization out of bed than explored here.
