Background: In 2015, the Australian government froze the Medicare Benefits Schedule Rebate (MBSR) for General Practitioner (GP) service use. This paper aimed to explore the impact of the MBSR freeze on the demand for GP services in Victoria, Australia, for three years, from 2014 to 2016.

Method: Annual data on GP service utilisation by the Victorian State Statistical Area Level 3 (SA3) were analysed using 2015 as the reference year (MBSR freeze year).

Fungal communities in Brazilian cassava tubers and food products.

Cassava (Manihot esculenta Crantz) is one of the most widely cultivated foods in the world and is of great socio-economic importance, especially in developing countries. It is predominantly consumed in boiled form, but also is used to produce a number of products, including cassava starch, sour starch, cassava flour and tapioca flour (hydrated cassava starch). Fungal spoilage can occur throughout the production chain, impairing both productivity and quality, as well as posing a potential risk of contamination by mycotoxins.

Obesity and Bariatric Surgery in Australia: Future Projection of Supply and Demand, and Costs.

Introduction: The prevalence of obesity is increasing in developed countries, including Australia. There is evidence that bariatric surgery is effective in losing weight and reducing risk of chronic diseases. However, access to bariatric surgery remains limited in the public health sector.

Delay to TKA in Patients Treated with a Multimodal Approach Using High Molecular Weight, Biologically Derived Hyaluronic Acid.

Background: The primary objective of this study was to determine the effect of single versus multiple rounds of intra-articular hyaluronic acid (IA-HA) in delaying the need for total knee arthroplasty (TKA) in patients with knee OA, and if additional benefits were seen when used in conjunction with other multimodal treatment options.

Methods: This study was a retrospective claims analysis of a large commercial database containing more than 100 million patients with continuous coverage from October 1, 2010 through September 30, 2015. Time to TKA for patients who received one course of Euflexxa (IA-BioHA) were compared to patients who received two or more courses of IA-BioHA and patients who received no IA-HA.

Accuracy of CGM Systems During Continuous and Interval Exercise in Adults with Type 1 Diabetes.

Background: continuous glucose monitoring systems (CGMs) play an important role in the management of T1D, but their accuracy may reduce during rapid glucose excursions. The aim of study was to assess the accuracy of recent rt-CGMs available in Italy, in subjects with T1D during 2 sessions of physical activity: moderate continuous (CON) and interval exercise (IE).

Method: we recruited 22 patients with T1D, on CSII associated or integrated with a CGM, to which a second different sensor was applied.

Aspergillus section Flavi and aflatoxins in Brazilian cassava (Manihot esculenta Crantz) and products.

Aflatoxins are carcinogenic compounds produced by some species of Aspergillus, especially those belonging to Aspergillus section Flavi. Their occurrence in food may start in the field, in the post-harvest, or during storage due to inadequate handling and storage. Because cassava is a staple food for a high percentage of the Brazilian population, we evaluated the presence of aflatoxin-producing species in cassava tubers, cassava products (cassava flour, cassava starch, sour starch, and tapioca flour), and in soil samples collected from cassava fields.

The diagnostic value of cytology in parotid Warthin's tumors: international multicenter series.

Introduction: Warthin's tumor (WT) is a common benign salivary gland neoplasm with a negligible risk of malignant transformation. However, there is a risk of malignant tumors being misdiagnosed as WT on cytology and inappropriately managed conservatively.

Methods: Patients from nine centers in Italy and the United Kingdom undergoing parotid surgery for cytologically diagnosed WT were included in this multicenter retrospective series.

Association between hepatitis C and B viruses and head and neck squamous cell carcinoma.

Background: Hepatitis B and C viruses are known to be carcinogenic and have been associated with the development of non-Hodgkin's lymphoma as well as hepatocellular carcinoma. The incidence of head and neck cancer is increasing worldwide, and early diagnosis is vital in order to achieve good oncological outcomes.

Objectives: To investigate the association between chronic hepatitis B and C infection, and head and neck squamous cell carcinoma (HNSCC).

Gelatin-genipin-based biomaterials for skeletal muscle tissue engineering.

Skeletal muscle engineering aims at tissue reconstruction to replace muscle loss following traumatic injury or in congenital muscle defects. Skeletal muscle can be engineered by using biodegradable and biocompatible scaffolds that favor myogenic cell adhesion and subsequent tissue organization. In this study, we characterized scaffolds made of gelatin cross-linked with genipin, a natural derived cross-linking agent with low cytotoxicity and high biocompatibility, for tissue engineering of skeletal muscle.

Effects of Magnetic and Electric Field Uniformity on Coded Aperture Imaging Quality in a Cycloidal Mass Analyzer.

Cycloidal mass analyzers are unique sector mass analyzers as they exhibit perfect double focusing, making them ideal for incorporating spatial aperture coding, which can increase the throughput of a mass analyzer without affecting the resolving power. However, the focusing properties of the cycloidal mass analyzer depend on the uniformity of the electric and magnetic fields. In this paper, finite element simulation and charged particle tracing were used to investigate the effect of field uniformity on imaging performance of a cycloidal mass analyzer.

Proof of Concept Coded Aperture Miniature Mass Spectrometer Using a Cycloidal Sector Mass Analyzer, a Carbon Nanotube (CNT) Field Emission Electron Ionization Source, and an Array Detector.

Despite many potential applications, miniature mass spectrometers have had limited adoption in the field due to the tradeoff between throughput and resolution that limits their performance relative to laboratory instruments. Recently, a solution to this tradeoff has been demonstrated by using spatially coded apertures in magnetic sector mass spectrometers, enabling throughput and signal-to-background improvements of greater than an order of magnitude with no loss of resolution. This paper describes a proof of concept demonstration of a cycloidal coded aperture miniature mass spectrometer (C-CAMMS) demonstrating use of spatially coded apertures in a cycloidal sector mass analyzer for the first time.

Coded Apertures in Mass Spectrometry.

The use of coded apertures in mass spectrometry can break the trade-off between throughput and resolution that has historically plagued conventional instruments. Despite their very early stage of development, coded apertures have been shown to increase throughput by more than one order of magnitude, with no loss in resolution in a simple 90-degree magnetic sector. This enhanced throughput can increase the signal level with respect to the underlying noise, thereby significantly improving sensitivity to low concentrations of analyte.

Prediction and real-time compensation of qubit decoherence via machine learning.

The wide-ranging adoption of quantum technologies requires practical, high-performance advances in our ability to maintain quantum coherence while facing the challenge of state collapse under measurement. Here we use techniques from control theory and machine learning to predict the future evolution of a qubit's state; we deploy this information to suppress stochastic, semiclassical decoherence, even when access to measurements is limited. First, we implement a time-division multiplexed approach, interleaving measurement periods with periods of unsupervised but stabilised operation during which qubits are available, for example, in quantum information experiments.

Is cardiorespiratory fitness impaired in PCOS women? A review of the literature.

Purpose: Polycystic ovary syndrome (PCOS) is a common and heterogeneous endocrine disorder, affecting 8-12% of reproductive-aged women. Insulin resistance and body fat excess are common features in these subjects. Increased physical activity and diet modifications are the first recommended approach in the management of these women, at least in overweight/obese subjects.

First steps to define murine amniotic fluid stem cell microenvironment.

Stem cell niche refers to the microenvironment where stem cells reside in living organisms. Several elements define the niche and regulate stem cell characteristics, such as stromal support cells, gap junctions, soluble factors, extracellular matrix proteins, blood vessels and neural inputs. In the last years, different studies demonstrated the presence of cKit cells in human and murine amniotic fluid, which have been defined as amniotic fluid stem (AFS) cells.

Metabolic Effects of Exercise.

Exercise has a powerful action on metabolism, and adaptation of the body to changes induced by exercise is fundamental to be able to provide the energy required for muscle contraction and physiological functions of vital tissues. Depending on the intensity and duration of exercise, different mechanisms are called on to make energy available, and under homeostatic control, this is guaranteed by rapid and coordinated changes in the secretion of several hormones. Molecular mechanisms controlling muscle function and fiber phenotype are related to the specific mode of muscle activation.
