Phytomedicines in Acute Rhinosinusitis: A Prospective,Non-interventional Parallel-Group Trial

Introduction

The objective of this prospective, multicenter, parallel-group, non-interventional clinical trial (NIT) was to characterize the effectiveness of a treatment with the phytomedicines ELOM-080 and BNO 1016 in patients with acute rhinosinusitis (ARS).

Methods

A total of 228 patients suffering from ARS took part in this NIT and were treated for a maximum of 14 days with either BNO 1016 or ELOM-080. Focus was on improvement of rhinosinusitis-associated pain/discomfort and nasal congestion in real-life conditions of primary care setting, as assessed by numeric and verbal rating scale, and five-point Likert scale.

Results

The course of the key ARS symptom facial pain demonstrated a faster recovery in patients with ELOM-080, when compared to BNO 1016. ELOM-080 tended to be superior for several ancillary criteria and induced significantly higher patient satisfaction with regard to the improvement of feeling of general illness. Physicians assessed both products to be very effective and well tolerated. Adverse drug reactions classified as gastrointestinal disorders occurred in both groups to a comparable extent.

Conclusion

This trial demonstrated comparable effectiveness of a therapy of ARS with the phytomedicines ELOM-080 and BNO 1016, although the treatment with ELOM-080 resulted in a more rapid and more complete recovery in ARS key symptoms and tended to be superior for several ancillary criteria. Both treatments were well tolerated.

Olanzapine vs haloperidol: treating delirium in a critical care setting

Objective

To compare the safety and estimate the response profile of olanzapine, a second-generation antipsychotic, to haloperidol in the treatment of delirium in the critical care setting.

Design

Prospective randomized trial

Setting

Tertiary care university affiliated critical care unit.

Patients

All admissions to a medical and surgical intensive care unit with a diagnosis of delirium.

Interventions

Patients were randomized to receive either enteral olanzapine or haloperidol.

Measurements

Patient’s delirium severity and benzodiazepine use were monitored over 5 days after the diagnosis of delirium.

Main results

Delirium Index decreased over time in both groups, as did the administered dose of benzodiazepines. Clinical improvement was similar in both treatment arms. No side effects were noted in the olanzapine group, whereas the use of haloperidol was associated with extrapyramidal side effects.

Conclusions

Olanzapine is a safe alternative to haloperidol in delirious critical care patients, and may be of particular interest in patients in whom haloperidol is contraindicated.

Toxicity and Pharmacokinetics of Sustained-Release Dexamethasone in Beagle Dogs

Introduction

The purpose of the present study was to examine the potential ocular and systemic toxicity and toxicokinetics/pharmacokinetics of sustained-release dexamethasone in canines.

Methods

In this non-randomized study, intracanalicular depots (dexamethasone-loaded or placebo vehicle) were inserted into both eyes of 33 beagles. Tear fluid and plasma were collected for toxicokinetic/pharmacokinetic analysis of dexamethasone, ophthalmic examinations were performed for signs of toxicity, and urine and blood samples were collected for urinalysis, hematology, clinical chemistry, and coagulation analysis. Animals were observed daily for signs of toxicity. Macroscopic and microscopic evaluations were performed.

Results

Mean dexamethasone tear fluid concentration from the dexamethasone group decreased from 4245 ng/mL 6-h post-insertion to 1044 ng/mL on Day 35. All plasma dexamethasone levels were below the limit of quantitation. No systemic or ocular toxicities were attributed to the dexamethasone depot.

Conclusion

Sustained-release dexamethasone produced no identifiable ocular or systemic toxicity in this animal model, and pharmacokinetics demonstrated a tapered, sustained drug release.

Perceptions of Oncologists,Healthcare Policy Makers,Patients and the General Population on the Value of Pharmaceutical Treatments in Oncology

Introduction

The purpose of this study was to explore the main factors explaining the relative weight of the different attributes that determine the value of oncologic treatments from the different perspectives of healthcare policy makers (HCPM), oncologists, patients and the general population in Spain.

Methods

Structured interviews were conducted to assess: (1) the importance of the attributes on treatment choice when comparing a new cancer drug with a standard cancer treatment; (2) the importance of survival, quality of life (QoL), costs and innovation in cancer; and (3) the most worrying side effects related to cancer drugs.

Results

A total of 188 individuals participated in the study. For all participants, when choosing treatments, the best rated characteristics were greater efficacy, greater safety, treatment adaptation to patients’ individual requirements and the rapid reincorporation of patients to their daily activities. There were important differences among participants in their opinion about survival, QoL and cost. In general, oncologists, patients, and the general population gave greater value to gains in QoL than healthcare policy makers. Compared to other participants healthcare policy makers gave greater importance to the economic impact related to oncology treatments.

Conclusions

Gains in QoL, survival, safety, cost and innovation are perceived differently by different groups of stakeholders. It is recommended to consider the perspective of different stakeholders in the assessment of a new cancer drugs to obtain more informed decisions when deciding on the most appropriate treatment to use.

Effects of Ketoconazole on the Pharmacokinetics of Mifepristone,a Competitive Glucocorticoid Receptor Antagonist,in Healthy Men

Introduction

Mifepristone, a competitive glucocorticoid receptor antagonist approved for Cushing syndrome, and ketoconazole, an antifungal and steroidogenesis inhibitor, are both inhibitors of and substrates for cytochrome P450 (CYP3A4). This study evaluated the pharmacokinetic effects of concomitant ketoconazole, a strong CYP3A4 inhibitor, on mifepristone.

Methods

In an open-label, two-period, single-center study, healthy adult men received mifepristone 600 mg orally daily for 12 days (period 1) followed by mifepristone 600 mg daily plus ketoconazole 200 mg orally twice daily for 5 days (period 2). Serial pharmacokinetic blood samples were collected predose and over 24 h postdose on days 12 (period 1) and 17 (period 2). A cross-study comparison (using data on file) further examined whether systemic exposure to mifepristone plus ketoconazole exceeded the exposure following mifepristone 1200 mg orally administered for 7 days.

Results

Sixteen subjects were enrolled and 14 completed the study. Concomitant administration with ketoconazole increased the systemic exposure to mifepristone, based on geometric least squares mean ratios, by 28% for C _max and 38% for AUC_0–24. This increase was 85% and 87% of the exposure observed following mifepristone’s highest label dose of 1200 mg/day for C _max and AUC_0–24, respectively. Adverse events (AEs) were reported in 56.3% (9/16) of subjects during administration of mifepristone alone and in 57.1% (8/14) during combination with ketoconazole. No serious AEs were reported.

Conclusion

Systemic exposure to mifepristone increased following multiple doses of mifepristone 600 mg daily plus ketoconazole 200 mg twice daily. Little to no increase in AEs occurred. Dose adjustment of mifepristone may be needed when given with ketoconazole.

Concurrent Improvement in Both Binge Eating and Depressive Symptoms with Naltrexone/Bupropion Therapy in Overweight or Obese Subjects with Major Depressive Disorder in an Open-Label,Uncontrolled Study

Introduction

Binge eating disorder (BED) is associated with obesity and major depressive disorder (MDD). Naltrexone extended-release (ER)/bupropion ER (NB) is approved as an adjunct to diet and physical activity for chronic weight management. In a prospectively designed 24-week open-label, single-arm, single-site trial of 25 women with MDD and overweight/obesity, NB reduced weight and depressive symptoms.

Methods

This post hoc analysis investigated the relationship between change in self-reported binge eating behavior (evaluated with the Binge Eating Scale [BES]) and changes in weight, control of eating, and depressive symptoms.

Results

At baseline, 91% of subjects had moderate or severe BES scores, suggesting BED. BES scores were significantly improved from week 4, and by week 24, 83% reported “little or no problem.” Improvement in BES scores correlated with improvement in depressive symptoms and control of eating.

Conclusion

NB may be effective in reducing binge eating symptoms associated with MDD and overweight/obesity. Evaluation of NB in BED appears warranted.

Ultrasonography evaluation during the weaning process: the heart,the diaphragm,the pleura and the lung

Purpose

On a regular basis, the intensivist encounters the patient who is difficult to wean from mechanical ventilatory support. The causes for failure to wean from mechanical ventilatory support are often multifactorial and involve a complex interplay between cardiac and pulmonary dysfunction. A potential application of point of care ultrasonography relates to its utility in the process of weaning the patient from mechanical ventilatory support.

Methods

This article reviews some applications of ultrasonography that may be relevant to the process of weaning from mechanical ventilatory support.

Results

The authors have divided these applications of ultrasonography into four separate categories: the assessment of cardiac, diaphragmatic, and lung function; and the identification of pleural effusion; which can all be evaluated with ultrasonography during a dynamic process in which the intensivist is uniquely positioned to use ultrasonography at the point of care.

Conclusions

Ultrasonography may have useful application during the weaning process from mechanical ventilatory support.

SkQ1 Ophthalmic Solution for Dry Eye Treatment: Results of a Phase 2 Safety and Efficacy Clinical Study in the Environment and During Challenge in the Controlled Adverse Environment Model

Introduction

This Phase 2 clinical trial assessed the efficacy and safety of the novel antioxidative, renewable compound SkQ1 for topical treatment of dry eye signs and symptoms.

Methods

In a single-center, randomized, double-masked, placebo-controlled, 29-day study, 91 subjects with mild to moderate dry eye instilled the study drug twice daily and recorded dry eye symptoms daily. Subjects were randomized 1:1:1 into one of three ophthalmic solution treatment groups: SkQ1 1.55 µg/mL, SkQ1 0.155 µg/mL, or 0.0 µg/mL (placebo). Subjects were exposed to a controlled adverse environment chamber at 3 of the 4 study visits (Day ?7, Day 1, and Day 29). Investigator assessments occurred at all study visits.

Results

SkQ1 was safe and efficacious in treating dry eye signs and symptoms. Statistically significant improvements with SkQ1 compared to placebo occurred for the dry eye signs of corneal fluorescein staining and lissamine green staining in the central region and lid margin redness, and for the dry eye symptoms of ocular discomfort, dryness, and grittiness. In addition, SkQ1 demonstrated greater efficacy compared to placebo, although the differences were not statistically significant, for corneal fluorescein staining in other regions and/or time points (total staining score, central region, corneal sum score, and temporal region), lissamine green staining for the central and nasal regions, and blink rate scores.

Conclusions

This Phase 2 study indicated that SkQ1 is safe and efficacious for the treatment of dry eye signs and symptoms and supported previous study results.

Incidence,treatment, and outcome of severe sepsis in ICU-treated adults in Finland: the Finnsepsis study

Objective

To determine the incidence and outcome of severe sepsis in the adult Finnish population and to evaluate how treatment guidelines in severe sepsis are applied in clinical practice.

Study design

A prospective study in 24 closed multidisciplinary ICUs in 21 hospitals (4 university and 17 tertiary hospitals) in Finland.

Patients

All 4,500 consecutive ICU admission episodes were screened for severe sepsis during a 4-month period (1 November 2004 – 28 February 2005). The referral population was 3,743,225.

Results

The severe sepsis criteria were fulfilled in 470 patients, who had472 septic episodes. The incidence of severe sepsis in the ICUs in Finland was 0.38/1000 in the adult population (95% confidence interval 0.34–0.41). The mean ICU length of stay was 8.2?±?8.1?days. ICU, hospital, and 1-year mortality rates were 15.5%, 28.3%, and 40.9%, respectively. Respiratory failure requiring ventilation support was the most common organ failure (86.2%); septic shock was present in 77% and acute renal failure in 20.6% of cases. Activated protein C was given to only 15 of the 55 patients with indication (27%) and low-dose corticosteroids to 150 of 366 (41%) patients with septic shock.

Conclusions

This prospective study found the incidence of ICU-treated severe sepsis in Finland to be 0.38 per 1,000 of the population. The ICU and hospital mortalities were also lower than earlier reported in United States or Australia. Evidence-based sepsis therapies were not used as often as recommended.

     

Effect of synbiotic therapy on the incidence of ventilator associated pneumonia in critically ill patients: a randomised,double-blind,placebo-controlled trial

Objective

To investigate the effect of enteral Synbiotic 2000 FORTE^® (a mixture of lactic acid bacteria and fibre) on the incidence of ventilator associated pneumonia (VAP) in critically ill patients.

Design

Prospective, randomised, double blind, placebo controlled trial.

Setting

Tertiary referral centre, general Adult Intensive Care Unit (ICU).

Patients and participants

259 enterally fed patients requiring mechanical ventilation for 48 h or more were enrolled.

Intervention

All patients were enterally fed as per a standard protocol and randomly assigned to receive either synbiotic 2000 FORTE^® (twice a day) or a cellulose-based placebo for a maximum of 28 days.

Measurements and results

Treatment group (n = 130) was well matched with placebo group (n = 129) for age (mean 49.5 and 50 years, respectively) and APACHE II score (median 17 for both). Oropharyngeal microbial flora and colonisation rates were unaffected by synbiotics. The overall incidence of VAP was lower than anticipated (11.2%) and no statistical difference was demonstrated between groups receiving synbiotic and placebo in the incidence of VAP (9 and 13%, P = 0.42), VAP rate per 1,000 ventilator days (13 and 14.6, P = 0.91) or hospital mortality (27 and 33%, P = 0.39), respectively.

Conclusions

Enteral administration of Synbiotic 2000 FORTE^® has no statistically significant impact on the incidence of VAP in critically ill patients.

     

Versatile,robust, and efficient tractography with constrained higher-order tensor fODFs

Purpose

Develop a multi-fiber tractography method that produces fast and robust results based on input data from a wide range of diffusion MRI protocols, including high angular resolution diffusion imaging, multi-shell imaging, and clinical diffusion spectrum imaging (DSI)

Methods

In a unified deconvolution framework for different types of diffusion MRI protocols, we represent fiber orientation distribution functions as higher-order tensors, which permits use of a novel positive definiteness constraint (H-psd) that makes estimation from noisy input more robust. The resulting directions are used for deterministic fiber tracking with branching.

Results

We quantify accuracy on simulated data, as well as condition numbers and computation times on clinical data. We qualitatively investigate the benefits when processing suboptimal data, and show direct comparisons to several state-of-the-art techniques.

Conclusion

The proposed method works faster than state-of-the-art approaches, achieves higher angular resolution on simulated data with known ground truth, and plausible results on clinical data. In addition to working with the same data as previous methods for multi-tissue deconvolution, it also supports DSI data.

Treatment of Rheumatoid Arthritis with Certolizumab Pegol: Results from PROACTIVE,a Non-Interventional Study in the UK and Ireland

Introduction

The objective of this non-interventional study was to investigate the long-term safety and effectiveness of certolizumab pegol (CZP) in patients with rheumatoid arthritis (RA) in the UK and Ireland.

Methods

Patients were prescribed CZP at their physicians’ discretion and followed during routine clinical practice for up to 88 weeks. DAS28(ESR) response (defined as at least a 1.2-point reduction from baseline) was measured in the full analysis set (FAS) at week 12, and patients were categorized by week 12 responder status in all subsequent analyses. The primary outcome was DAS28(ESR) response at week 78. Secondary outcomes included change from baseline in DAS28(ESR), HAQ-DI, and RADAI scores at week 78, and EULAR response at week 78. Adverse drug reactions (ADRs) were recorded for all patients who received at least one dose of CZP.

Results

A total of 149 patients were enrolled, of whom 111 (74.5%) formed the FAS. At week 12, 80 patients (72.1%) were DAS28(ESR) responders and 31 (27.9%) non-responders. Compared to non-responders, a greater proportion of week 12 responders had a DAS28(ESR) response at week 78 (43.8% versus 22.6%). Improvements in DAS28(ESR), HAQ-DI, and RADAI scores were also greater on average among week 12 responders, as was the proportion of patients meeting EULAR criteria. Overall, 9 patients (6.1%) experienced 13 ADRs during the study.

Conclusion

These data demonstrate the safety and effectiveness of CZP in adult patients with RA treated during routine clinical practice in the UK and Ireland.

Impact of Region-of-Interest Delineation Methods,Reconstruction Algorithms,and Intra- and Inter-Operator Variability on Internal Dosimetry Estimates Using PET

Purpose

Human dosimetry studies play a central role in radioligand development for positron emission tomography (PET). Drawing regions of interest (ROIs) on the PET images is used to measure the dose in each organ. In the study aspects related to ROI delineation methods were evaluated for two radioligands of different biodistribution (intestinal vs urinary).

Procedures

PET images were simulated from a human voxel-based phantom. Several ROI delineation methods were tested: antero-posterior projections (AP), 3D sub-samples of the organs (S), and a 3D volume covering the whole-organ (W). Inter- and intra-operator variability ROI drawing was evaluated by using human data.

Results

The effective dose estimates using S and W methods were comparable to the true values. AP methods overestimated (49 %) the dose for the radioligand with intestinal biodistribution. Moreover, the AP method showed the highest inter-operator variability: 11 ± 1 %.

Conclusions

The sub-sampled organ method showed the best balance between quantitative accuracy and inter- and intra-operator variability.
