How Open Data Can Reveal—And Correct—The Faults In Our Health System

We examined sites of service for non-complex office visits across gastroenterology, cardiology, and oncology — three specialties that tend to deliver care across a range of sites. Medicare reimbursement is higher for hospital visits as compared to those in a physician office. Overall, we found that most doctors bill regular, level 3 evaluation and management visits in non-hospital settings. Oncologists have the highest percentage billed in hospital-type facilities — 15 percent of non-complex office visits. In this case, we were limited in our analysis because the dataset does not include the additional amount that is paid in hospital settings. Over and Underutilization of Procedures and Services Improper utilization of procedures can often be indicators of medical inefficiency or fraud. One analysis of possible overutilization pulled from this dataset has been conducted by the investigative reporting nonprofit ProPublica. Since Medicare codes patient visits on a scale of complexity, one being the least complex and five being the most complex, ProPublica highlighted providers billing for mostly complex, expensive visits at seemingly unexplainably high rates. Their analysis spurred conversations around Medicare billing practices for outpatient visits — in general, it was considered unlikely that providers should only be billing at the highest complexity levels; patient-level data on outcomes or risk adjustment—not included in the data release—would...

Abstract Retrospective analysis has already shown correlation between severe Chronic Periodontitis (CP) cases with human papiloma virus (HPV). Hence, we aimed to explore deep-seated infected granulation tissue removed during periodontal flap surgery procedures for residential bacterial species between HPV+ and HVP- CP cases, which may serve as good predisposition marker for oral cancer. All CP-granulation samples showed the prominence of Firmicutes, Proteobacteria, and Bacteroidetes phyla with an abundance of gram negative anaerobes, except Streptococcus. In Beta diversity nonmetric multidimensional scaling plot, ...

Abstract An important harmonization effort was produced by the scientific community to standardize both the preanalytical and interpretative phases of programmed death-ligand 1 (PD-L1) immunohistochemical (IHC) testing in non-small-cell lung cancer (NSCLC). This analysis is crucial for the selection of patients with advanced-stage tumors eligible for treatment with pembrolizumab and potentially with other anti-PD-1/PD-L1 checkpoint inhibitors. This multicentric retrospective study evaluated the reproducibility of PD-L1 testing in the Italian scenario both for closed and open platforms. In the evaluation of the wel...

Photodynamic therapy (PDT) has emerged as an alternative and a promising minimally invasive treatment modality for certain types of cancers and is becoming adapted in clinics nowadays. For example, in dermatology, PDT is gradually becoming the reference treatment for actinic keratoses (KA), superficial basal cell carcinomas and Bowen's disease [1]. In ophthalmology, PDT with Visudyne ® has been very popular in the treatment of patients with Age-related macular degeneration [2]. In urology, the French company Steba-Biotech [3] has developed Tookad® as a new PS for the treatment of prostate cancer.

ConclusionsThe ancillary studies allowed study sites to broaden the research opportunities for their participants. Their implementation was efficient because of the established infrastructure of the primary trial. Implementation of these ancillary trials took substantial planning and coordination but enriched the overall primary trial.Trial registrationNCT00006392-S0000: Selenium and Vitamin E in Preventing Prostate Cancer (SELECT) (4 October 2000).NCT00780689-S0000A:   Prevention of Alzheimer’s Disease by Vitamin E and Selenium (PREADVISE) (25 June 2002).NCT00784225-S0000B: Vitamin E and/or Selenium in Preventi...

Abstract There is an increasing demand for carotenoids, which are fundamental components of the human diet, for example as precursors of vitamin A. Carotenoids are also potent antioxidants and their health benefits are becoming increasingly evident. Protective effects against prostate cancer and age-related macular degeneration have been proposed for lycopene and lutein/zeaxanthin, respectively. Additionally, β-carotene, astaxanthin and canthaxanthin are high-value carotenoids used by the food industry as feed supplements and colorants. The production and consumption of these carotenoids from natural sources,...
