This is a theoretical paper examining the effect of user fee on patients’ welfare and social welfare under three forms of provider reimbursements: full cost, prospective payment and cost sharing. The paper extends Rickman and McGuire (1999) by introducing user fee to the public sector and maintaining the assumption that providers can work in both the private and public health sectors. Contrary to previous studies, this study shows that efficiency is possible under the full cost reimbursement. The paper also shows the conditions under which efficiency is possible under each reimbursement scheme. Patient’s welfare can improve with the introduction of user fee when services in the public and private sector are complementary.

AIM: To determine the hypothesis that inflating the balloons in the duodenal papilla determines changes in the biochemical markers of ***: Four groups of pigs were used: Group papilla(GP), the overtube's balloon was inflated in the area of the papilla; GP + double balloon enteroscopy(GP + DBE), the overtube's balloon was kept inflated in the area of the papilla for 20 min before a DBE; Group DBE(GDBE), DBE was carried out after insuring the balloon's inflation far from the pancreatic papilla; and Group control(GC). Serum concentrations of amylase, lipase and C-reactive protein(CRP) were evaluated. Pancreases were processed for histopathology ***: Main changes occurred 24 h after the procedure compared with baseline levels. Amylase levels increased significantly in GP(59.2% higher) and were moderately higher in groups GP + DBE and GDBE(22.7% and 20%, respectively). Lipase increased in GP and GP + DBE, whereas it hardly changed in GDBE and in GC. CRP increased significantly in GP, GP + DBE and GDBE, while no changes were reported for GC. No statistically significant difference between groups GP and GP + DBE was found for the histopathological findings, except for vacuolization and necrosis of the pancreatic parenchyma that was higher in GP than in GP + ***: The manipulation of the duodenal papilla by the inflated overtube's balloon during DBE causes pancreatic structural damage and increased biochemical markers associated with pancreatitis.

Early discharge policy, common in the developed countries, refers to the reduction of hospital length of stay as a way of reducing the cost of care. The effect of the policy on quality of care has received a lot of attention in the literature. Some of the earlier papers have ignored the endogeneity of length of stay in the readmission equation, an approach that could lead to inconsistent estimation. This study develops a statistical technique for the consistent estimation of the effect of the early discharge policy. An instrument that can be used extensively across different diagnostic groups is provided, hence solving the difficult problem of finding an instrument for length of stay. The exogeneity test in Gorgger (1990), the test for weak instruments in Staiger and Stock (1997) as well as the Hensen (1982) for over identification confirmed respectively that length of stay is endogenous the instrument is strong and the valid.

The difficulty of assessing funds to directly fund healthcare for the poor makes governments adopt user fee in the health system. Many studies have shown how user fee can cause the poor to under utilize healthcare but not on how it can lead to the waste of resources. The current study is theoretical and it examines the efficiency of regulated user fee and the factors affecting the efficiency. Efficiency focused mainly on the extent to which resources are wasted as a result of regulated user fee. The results show that the asymmetric information between the provider of healthcare and the patient combined with the costliness of investigation by the government as well as the costliness of revenue collection caused three sources of waste: excessive treatment of the rich or the non-poor, investigation and revenue collection. Comparative statics were done to examine the effect of various factors on the level of waste. The study then examined the conditions under with regulated user fee is more efficient than direct financing of healthcare by the government. Some recommendations were made to reduce wastes.

The plant steroid hormones, brassinosteroids （BRs）, and their precursors, phytosterols, play major roles in plant growth, development, and stress tolerance. Here, we review the impressive progress made during recent years in elucidating the components of the sterol and BR metabolic and signaling pathways, and in understanding their mecha- nism of action in both model plants and crops, such as Arabidopsis and rice. We also discuss emerging insights into the regulations of these pathways, their interactions with other hormonal pathways and multiple environmental signals, and the putative nature of sterols as signaling molecules.

AIMTo study the prevalence, characteristics, risk factors and mortality at 28 d of acute-on-chronic liver failure (ACLF). METHODSA total of 100 cirrhotic patients admitted to our hospital for more than one day were included during the period between June 2013 and December 2015. We used the European Association for the Study of the Liver-Chronic Liver Failure-Consortium diagnostic criteria for ACLF, considering it as the acute decompensation of cirrhosis associated with the presence of one or more organ failure. For the diagnosis of organic failure the Chronic Liver Failure-Sequential Organ Failure Assessment score was used. Our population was divided into patients with and without ACLF. Clinical characteristics, presence of precipitating events, potential risk factors for developing ACLF and causes of mortality were analyzed. Mortality at 28 d was evaluated. RESULTSTwenty-nine patients (29%) developed ACLF criteria. Alcoholism, detected in 58 patients (58%), was the major etiological agent of cirrhosis. Bacterial infections were recognized as a precipitating event in 41.3% of cases and gastrointestinal bleeding in 27.5%. No precipitating event was identifiable in 27.5% of patients with ACLF. Comparing patients with and without ACLF, statistically significant risk factors were: Child Pugh score 10.2 ± 2.1 vs 8.4 ± 1.6 (P ˂ 0.0001), MELD score 20.7 ± 8.5 vs 12.3 ± 4 (P ˂ 0.0001), presence of ascites 27 (93%) vs 43 (60.5%) (P = 0.001), leukocytosis 15300 ± 8033 per cubic millimeter vs 10770 ± 5601 per cubic millimeter (P ˂ 0.0001), and high plasma levels of C reactive protein values 50.9 ± 46.4 mg/L vs 28.6 ± 23.4 mg/L (P ˂ 0.0019). Mortality rate was 62% (18 patients) vs 5.6% (4 patients), respectively (P CONCLUSIONWe observed that the ACLF is a frequent entity in this group of patients and has a significantly higher mortality rate.
