BACKGROUND: Parkinson's disease (PD) is a progressive disorder of the central nervous system. The prevalence of PD varies considerably by age group; it has a higher prevalence in patients aged 60 years and more. Several studies have shown that statin, a cholesterol-lowering medication, reduces the risk of developing PD, but evidence for this is so far inconclusive. The objective of this study is to evaluate the association between statin use and the risk of developing PD. METHODS: PubMed, EMBASE, and the bibliographies of articles were searched for studies published between January 1, 1990, and January 1, 2017, which reported on the association between statin use and PD...

The fate of the pharmaceutical drugs tenoxicam, piroxicam and meloxicam in river water is evaluated here for first time. So, biological, photochemical and thermal degradation assays have been conducted to estimate their degradation rates and know their degradation products. Results indicated that the direct sunlight irradiation, without any protection, promoted a fast degradation of the oxicams while the chemical reactions in solution were less important. The biological degradation in water was negligible except for tenoxicam in whose case its influence was scarce...

SGLT-2 inhibitors, also called gliflozins, are a new class of drugs used in type 2 diabetes. Since their marketing, several cases of ketoacidosis, including life-threatening conditions, were reported with their use. The objective of this study was to investigate the disproportionality of pharmacovigilance reports of ketoacidosis between gliflozins and other drugs used for type 2 diabetes. We performed a case non-case study within the World Health Organization's pharmacovigilance database, VigiBase. We selected all reports of serious adverse drug reaction associated with a glucose-lowering drug in patients aged 40 years and older, from January 2013 to March 2016...

Aluminum is a common contaminant in many components of parenteral nutrition, especially calcium and phosphate additives. Although long-term effects have been described in the literature, short-term effects are not well-known. Currently, the Food and Drug Administration recommends maintaining aluminum at <5 mcg/kg/day. This was a single center, retrospective case-control study of 102 neonatal intensive care unit patients. Patients were included if they had a diagnosis of necrotizing enterocolitis, rickets/osteopenia, or seizures and received at least 14 days of parenteral nutrition...

Drugs carry a proarrhythmic risk, which gets even greater when they are used in combination. In vitro assessment of the proarrhythmic potential of drugs is limited to one compound and thus neglects the potential of drug-drug interactions, including those involving active metabolites. Here we present the results of an in vitro study of potential drug-drug interactions at the level of the hERG channel for the combination of up to three compounds: loratadine, desloratadine and ketoconazole. Experiments were performed at room temperature on an automated patch-clamp device CytoPatch 2, with the use of heterogeneously, stably transfected HEK cells...

OBJECTIVE: Among children with epilepsy, to develop and evaluate a model to predict emergency department (ED) use, an indicator of poor disease control and/or poor access to care. METHODS: We used electronic health record data from 2013 to predict ED use in 2014 at 2 centers, benchmarking predictive performance against machine learning algorithms. We evaluated algorithms by calculating the expected yearly ED visits among the 5% highest risk individuals. We estimated the breakeven cost per patient per year for an intervention that reduced ED visits by 10%...

BACKGROUND: Achieving the Sustainable Development Goals will require careful allocation of resources in order to achieve the highest impact. The Lives Saved Tool (LiST) has been used widely to calculate the impact of maternal, neonatal and child health (MNCH) interventions for program planning and multi-country estimation in several Lancet Series commissions. As use of the LiST model increases, many have expressed a desire to cost interventions within the model, in order to support budgeting and prioritization of interventions by countries...

OBJECTIVE: Paediatric laboratory reference intervals used in Africa and Asia may be derived from historical intervals of predominantly Caucasian infants in Europe or North America. These intervals may therefore not be compatible with the range of normality for developing country populations. We aimed to compare haematology and biochemistry parameters in healthy South African infants with local laboratory reference intervals. METHODS: We compared the baseline haematology and biochemistry results of 634 (316 male and 318 female) HIV-unexposed infants, aged 3-6 months, living in a rural area of the Western Cape Province, South Africa, against laboratory reference intervals supplied by the South African National Health Laboratory Services (NHLS)...

Bromodomains (BRDs) have been an attractive candidate for development of efficient inhibitors toward gene transcription. Molecular dynamics (MD) simulations followed by principal component (PC) analysis were performed to investigate binding selectivity of inhibitors RVX297, BSP, JQ1, SF2523 and CPD2 toward two domains (BD1 and BD2) of bromodomain-containing protein 4 (BRD4). The results show that inhibitor bindings exert different effect on motions of the BC-loops in BD1 and BD2. The rank of binding free energies calculated by using molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) method agrees with the one determined by experiment...

Despite increase in the understanding of the pathogenesis of rheumatoid arthritis (RA), it remains a tough challenge. The advent of kinases involved in key intracellular pathways in pathogenesis of RA may provide a new phase of drug discovery for RA. The present study is aimed to identify dual JAK3/[Formula: see text] inhibitors by developing an optimum pharmacophore model integrating the information revealed by ligand-based pharmacophore models and structure-based pharmacophore models (SBPMs). For JAK3 inhibitors, the addition of an aromatic ring feature and for [Formula: see text] the addition of a hydrophobic feature proposed by SBPMs lead to five-point pharmacophore (i...

There are limited treatment options available for women with moderate to severe symptoms of uterine fibroids (UFs) who wish to avoid surgery. For these women, treatment with standard pharmaceuticals such as contraceptives is often insufficient to relieve symptoms, and patients may require surgery despite their wish to avoid it. Clinical trials demonstrate that ulipristal acetate 5 mg (UPA) is an effective treatment for this patient group, but its cost-effectiveness has not been assessed in this population. A decision-analytic model was developed to simulate a cohort of patients in this population under treatment with UPA followed by surgery as needed compared to treatment with iron and non-steroidal anti-inflammatory drug (NSAID) followed by surgery as needed (best supportive care, BSC)...

Body surface area(BSA)is a parameter frequently used to calculate the chemotherapy dosage. Several different equations for predicting BSA have been developed. We examined the formula suggested for BSA calculation for 62 chemotherapy drugs where the recommended dosage was based on patient BSA. We found that the description of the formula to be used for BSA calculation was not provided in the package inserts or in the drug interview forms in the majority of cases; the BSA formula was mentioned in the guide for appropriate use of medication in only 8 of 62 chemotherapy drugs...
