In general, more PVP conditioned a larger discrepancy of the internal vs. external porosity. When the external porosity of the LPP formulation (15% of PVP during the manufacturing process) was less than 3%, the burst release of the embedded drug was significantly reduced compared to LPPs prepared by a "conventional" emulsification solvent evaporation method. All the formulations prepared by the PME-SE method had aerodynamic properties suitable for inhalation. This is the first report indicating that the microstructure of LPPs can be tailored using the PME-SE technology with PVP as a suitable pore former. Doing so, we designed LPP formulations having full control over the drug release kinetics and aerodynamic behavior.Hot melt extrusion (HME) is a widely used manufacturing process for pharmaceutical solid dispersions. The complexity of the HME formulations and the number of excipients used in the process are increasing with the advancement of the relevant knowledge. However, one of the areas that is still significantly lacking understanding is the control of internal microstructure of extrudates. Internal microstructure, consisting of voids, in hot melt extruded amorphous solid dispersions is often observed without the causes having been systemically investigated in the literature. In this study, we investigated a range of factors that demonstrated their impacts on the formation of the voids. These include the effect of the types of the materials (i.e. drug, polymer and additive) used in the formulation, the quantity of the drug and the additives used, the key extrusion processing parameters, the type of extruder, and the drying of the raw materials prior to extrusion. The results indicate that the appropriate viscosity and the presence of phase-separated particulates are essential for the formation of the voids. The particulates act as nuclei for the entrapped gas bubbles and the viscosity of the mixture during extrusion governs the collapse/escape of the bubbles. To minimise void formation, the results of this study indicate that slow screw speed, low moisture content of the raw materials, fewer particulates and the addition of lubricants, such as low melting lipid excipients, could be beneficial.

In the present study, a retrospective, descriptive, questionnaire-based survey was conducted to clarify the current status of drug compounding for pediatric patients in Japan. An electronic questionnaire was distributed to 740 hospitals in Japan with pediatric beds, and 208 (28.1%) of these hospitals responded. The total instances of compounding numbered 14,864 (9.6% of the total pediatric oral prescriptions) and comprised 266 active pharmaceutical ingredients (APIs), one-third of which (98 APIs) were compounded even though flexible dosage forms were available. The three most frequently compounded drugs were dantrolene sodium capsules (1152 prescriptions), ramelteon tablets (726 prescriptions), and hydrocortisone tablets (652 prescriptions), all of which were prescribed and administered in powder form. Although compounding of medications frequently varied by the patients' age, steroids such as prednisolone, dexamethasone, and hydrocortisone were commonly compounded in all age groups. To ensure the quality and safety of these compounded medications, developing a standard protocol for compounding methods is urgently needed in Japan.SARS-CoV-2 pandemic had changed self-care in diabetes. The aim of this work is to analyze the effect of lockdown on glycemic control in people with type 1 diabetes on multiple daily insulin injections using FGM. During lockdown no deleterious effect on glycemic control measured by FGM.

Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease and also closely related to cardiometabolic disease. Its prevalence was estimated at over one-fourth in the general population in China. We aimed to develop effective score tools for detecting NAFLD.

A total of 17,212 participants aged 45-70years old were surveyed in Shanghai between 2013 and 2014, and 13,293 participants were included in this analysis. All participants were randomly classified into the exploratory group or the validation group. Candidate categorical variables were selected using a logistic regression model. The score points were generated according to the β-coefficients.

We developed the Shanghai Nicheng NAFLD Score I (SHNC NAFLD Score I), which included body mass index and waist circumference with an area under the receiver-operating characteristic curve (AUC) of 0.802 (95% CI 0.792-0.811) in the exploratory group and 0.802 (95% CI 0.793-0.812) in the validation group. We further developed the SHNC NAFLD Score II by adding fasting plasma glucose, triglyceride, and alanine aminotransferase/aspartate aminotransferase ratio to the SHNC NAFLD Score I, achieving an AUC of 0.852 (95% CI 0.843-0.861) in the exploratory group and 0.843 (95% CI 0.834-0.852) in the validation group. The two score tools also performed well in subjects with normal alanine aminotransferase (ALT) levels.

Based on anthropometric and clinical categorical variables, our two scores are effective tools for detecting NAFLD in both this southern Chinese population and their subpopulation with normal ALT levels.

Current USPSTF guidelines recommend screening asymptomatic, overweight patients greater than 40 years. Our study showed that ¼ of patients with type 2 diabetes were diagnosed prior to 40 years. Therefore, we recommend lowering the screening age for diabetes.
