Information asymmetries and supplier induced demand (an economic study for the french market)
1990
The supplier induced demand hypothesis relies on the existence of information asymmetry between the physician and his patient. This asymmetry confers a discretionary power on practitioners who are using it in order to satisfy their own interest. The inducement effect is identified and distinguished from the other consequences of information asymmetries in the health care system, i.e. moral hazard and adverse selection. A controversy is generated by the induced demand hypothesis which constitutes a challenge to the assumption of the independence of supply and demand and, therefore, contradicts standard neoclassical predictions. The role of empirical studies is important in this respect. An e…
Psychological interventions for resilience enhancement in adults
2017
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the effects of resilience‐enhancing interventions in clinical and non‐clinical populations.
Associations of Antifungal Treatments With Prevention of Fungal Infection in Critically Ill Patients Without Neutropenia
2017
BACKGROUND: Invasive fungal infections are important causes of morbidity and mortality among critically ill patients. Early institution of antifungal therapy is pivotal for mortality reduction. Starting a targeted antifungal therapy after culture positivity and fungi identification requires a long time. Therefore, alternative strategies (globally defined as 'untargeted antifungal treatments') for antifungal therapy institution in patients without proven microbiological evidence of fungal infections have been discussed by international guidelines. This review was originally published in 2006 and updated in 2016. This updated review provides additional evidence for the clinician dealing with …
Chemotherapy for advanced gastric cancer
2017
Background Gastric cancer is the fifth most common cancer worldwide. In "Western" countries, most people are either diagnosed at an advanced stage, or develop a relapse after surgery with curative intent. In people with advanced disease, significant benefits from targeted therapies are currently limited to HER-2 positive disease treated with trastuzumab, in combination with chemotherapy, in first-line. In second-line, ramucirumab, alone or in combination with paclitaxel, demonstrated significant survival benefits. Thus, systemic chemotherapy remains the mainstay of treatment for advanced gastric cancer. Uncertainty remains regarding the choice of the regimen. Objectives To assess the effica…
Immune checkpoint inhibitors plus chemotherapy versus chemotherapy or immune checkpoint inhibitors for first- or second-line treatment of advanced ga…
2019
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To evaluate the efficacy and safety of immune checkpoint inhibitors, alone or in combination with chemotherapy, in people with advanced gastric and gastroesophageal junction adenocarcinoma in first and subsequent treatment lines.
Emergency sclerotherapy or band ligation combined with vasoactive drugs for bleeding esophageal varices in cirrhosis
2019
This is a protocol for a Cochrane Review (Intervention). The objectives are as follows: To assess the efficacy as well as adverse events of emergency sclerotherapy (or band ligation) combined with pharmacological treatments versus sclerotherapy (or band ligation) alone or vasoactive drugs alone for acute variceal bleeding in cirrhotic patients based on the results of randomised clinical trials (RCTs).
DFT studies of COOH tip-functionalized zigzag and armchair single wall carbon nanotubes
2011
Structure and energy calculations of pristine and COOH-modified model single wall carbon nanotubes (SWCNTs) of different length were performed at B3LYP/6-31G* level of theory. From 1 to 9 COOH groups were added at the end of the nanotube. The differences in structure and energetics of partially and fully functionalized SWCNTs at one end of the nanotube are observed. Up to nine COOH groups could be added at one end of (9,0) zigzag SWCNT in case of full functionalization. However, for (5,5) armchair SWCNT, the full functionalization was impossible due to steric crowding and rim deformation. The dependence of substituent attachment energy on the number of substituents at the carbon nanotube ri…
