Nanoparticles are used in a variety of fields; for example, titanium oxide nanoparticles are used in paints, food additives, cosmetics, and sunscreen materials. Although the use of titanium oxide nanoparticles is regulated, their safety has not been established. Furthermore, the interaction between titanium oxide nanoparticles and various chemical substances and pharmaceuticals is unknown. We co-administered rutile-type titanium oxide nanoparticles (nTR) or anatase-type titanium oxide nanoparticles (nTA) to mice together with paraquat (PQ), cisplatin (CDDP), or anti-5-aminosalicylic acid (5-ASA), and investigated the extent, if any, of liver and kidney injury...

Background and aim: Medication errors lead to preventable risks. Preventing strategies such as e-prescribing, clinical pharmacists and medication reconciliation have been implemented in recent years. However, information on long-term medication error rates in routine procedures is missing. Investigations: We aimed to identify predefined medication errors in ten wards of a university hospital where e-prescribing, clinical pharmacists and medication reconciliation have been partially implemented. Patient files were reviewed and routine processes were monitored for drug prescription errors (missing, unclear, outdated information), administration errors (wrong dispensed drugs) and drug handling errors (no light-, moisture-protection, wrong splitting, no separation of drugs, which ought to be taken by an empty stomach)...

Background: The use of generative artificial intelligence (AI) applications such as ChatGPT is becoming increasingly popular. In Japan, consumers can purchase most over-the-counter (OTC) drugs without having to consult a pharmacist, so they may ask generative AI applications which OTC drugs they should purchase. This study aimed to systematically evaluate responses from ChatGPT to consumer inquiries about various OTC drugs. Methods: We selected 22 popular OTC drugs and 12 typical consumer characteristics, including physical and disease conditions and concomitant medications...

Promoting antidiabetic phytomedicines necessitates evidence-based preclinical investigations, particularly in animal models. The present study investigated the validity of using the streptozotocin-nicotinamide-induced type 2 diabetic (STZ/NA-induced T2DM) model to evaluate the effects of Physalis peruviana leaf crude extracts on controlling blood glucose levels and regulating physiological biomarkers in rats. Aqueous and methanol extracts dissolved in carboxymethylcellulose 1% (100, 200, mg/kg/day) were administered orally to STZ/NA-induced T2DM rats alongside glibenclamide (5 mg/kg) as the standard drug for four weeks...

Video-assisted thoracic surgery esophagectomy (VATS-E) may increase the risk of postoperative nausea and vomiting (PONV) because it uses a high dosage of anesthesia through a long operative duration. However, no study has examined the risk factors for PONV after VATS-E. Therefore, we investigated the risk factors for PONV to support the appropriate risk management of PONV after VATS-E. This prospective cohort study included 155 patients who underwent VATS-E at the Showa University Hospital between April 1st, 2020 and November 30th, 2022...

Background and aim: Drug-related problems (DRPs), e.g.drug-drug interactions (DDI), can lead to adversedrug reactions (ADRs) and thus complications during hospitalization. For this reason, such DRP, DDI and ADR should be identified and characterized as early as possible during hospital admission. We aimed to perform a clinical-pharmaceutical medication reconciliation in which patient-related information was collected and compared to drug-related information in a medication review. Investigations: During a 24-week-period, we consecutively invited patients electively admitted to Urology, Otolaryngology, Oral and Maxillofacial Surgery, General and Visceral Surgery, and Oncology Departments of a 300-bed hospital...

Zinc is an essential microelement, and its deficit causes various diseases and symptoms. In adults, especially in elderly individuals, zinc shortage can cause symptoms such as taste disorder, dermatitis, and susceptibility to infection. In children, zinc deficiency can lead to growth retardation. In 2017, the indication for zinc acetate dihydrate (NOBELZIN® ) was expanded from Wilson's disease to include hypozincemia, leading to wider use of zinc acetate dihydrate. At five years after this broadening of use, we conducted a post-marketing study (PMS) to investigate the utilization, safety, and effectiveness of zinc acetate dihydrate...

The global pandemic of COVID-19 disease is caused by the pathogenic factor called SARS-CoV-2. Meanwhile, a series of vaccines and small-molecule drugs, including the mRNA vaccines and Paxlovid® , have been approved, but their efficacy is decreased significantly due to the constant emergence of mutant viral strains. The R&D of host-directed therapeutics has great potential to overcome such limitations and provide new prevention and therapy options for patients with COVID-19 or high-risk group for SARS-CoV-2 infections...

Immunoglobulin replacement therapy (IgRT) has advanced over the years and is used to treat many patients with primary immunodeficiencies reducing the number of infections and the burden of disease. We investigated the perception of IgRT in two patient groups (UKPIPS and PID UK) and their condition through a short survey. The survey was a multiple-choice short survey consisting of 20 questions completed either online or on paper. Data analysis was performed using SAS analysis software using regression analysis, correlation analysis and t-tests...

Objective : Magnesium oxide is widely used for treating opioid-induced constipation, a serious analgesic-associated problem. Opioid analgesic users are often prescribed non-steroidal anti-inflammatory drugs, which are sometimes combined with acid suppressants to prevent gastrointestinal adverse events. Magnesium preparations combined with acid suppressants may diminish magnesium preparations' laxative effect. This study was aimed at evaluating the effect of magnesium preparations combined with acid suppressants on the incidence of opioid-induced constipation by using the Food and Drug Administration Adverse Event Reporting System...

New anti- Toxoplasma gondii agents are in demand due to the emergence of high toxicity. Ginseng polysaccharides and saponins can be used to treat the replication of Toxoplasma gondii in an attempt to determine whether the medicinal uses of ginseng are supported by pharmacological effects. Anti- Toxoplasma gondii activities of ginseng polysaccharides and saponins were examined in vitro and in vivo . The findings are the survival time and rate of Toxoplasma gondii infected mice after the intake of the total polysaccharides and saponins increased compared to untreated control mice...

In patients with type 2 diabetes mellitus (T2DM), controlling serum uric acid (SUA) and blood glucose levels is important. Moreover, sodium-glucose cotransporter 2 (SGLT2) inhibitors decrease SUA levels by accelerating urinary uric acid excretion. We investigated the effect of baseline urinary glucose levels on the relationship between SGLT2 inhibitors and SUA levels. We conducted a retrospective observational study using the electronic medical records of patients with T2DM of Kindai University Nara Hospital (April 2013 to March 2022)...

Free amino acids constitute the largest portion (40%) of the natural moisturizing factor. Their level might decline and cause dry skin condition. The treatment strategy involves the replenishment of these components to the skin, and, to our knowledge, there are no reports that involve dermal delivery of free amino acids. The purpose of the current study was therefore to prepare and characterize different micro-emulsions, micro-emulsion-based hydrogels, and hydrophilic creams loaded with free amino acids for dermal delivery...

Endoplasmic reticulum stress (ER stress) is suggested to promote cardiomyocyte apoptosis and ultimately lead to ischemic injury. Inhibition of ER stress-induced apoptosis may be a therapeutic strategy for MI injury. Astragaloside-IV (AST) from Astragalus membranaceus (Fisch) Bge, was reported to have cardioprotective properties. In this study, we investigated the protective effect of AST on cardiomyocytes against hypoxia injury by regulating ER stress and inhibiting apoptosis. H9c2 cardiomyocytes were divided into three groups, normal group, hypoxia group and AST group...

Bisphosphonate (BPN) therapy, which mainly targets osteoporosis, evolves rapidly, leaving patients and physicians with a substantial collection of BPN regimen options. In this study, we aimed to clarify BPN medication adherence between weekly and monthly regimens using a nationwide claims database in Japan. We analyzed 5,016 patients with a screening period of 3 months and a 12 month observation period who started using BPN. We used propensity score matching with baseline patient background after dividing the patients into two groups: weekly and monthly BPN users...

The antitumor drug candidate X-05 is being developed as an innovative anti-lung cancer drug candidate due to its excellent antitumour activity. A Caco-2 cell permeability study and solubility study confirmed that X-05 belonged to BCS class or compounds. Therefore, the main challenge is to develop appropriate preparations for preclinical studies and further clinical phase research. By evaluating the preliminary results of kinetic solubility in biorelevant media and the structural analysis of X-05 and polymers, three polymers PVP K30, PVP VA 64 and HPMCAS, which may have intermolecular interactions with X-05, were chosen to select the optimal carrier for X-05 to prepare amorphous solid dispersions (ASDs)...

This study aimed to determine the efficacy of zinc acetate hydrate (ZAH) for hypozincemia in elderly hospitalized patients with an accumulated exposure of < 1000 mg of ZAH and to explore the factors affecting the therapeutic efficacy of ZAH. Seventy-four patients (mean age, 82 years) were enrolled in this study. All patients (n = 74) had low serum zinc levels (< 80 μg/dL), and the mean serum zinc concentration before ZAH administration was 53.6±10.7 μg/dL. The median serum zinc level (μg/dL) elevated per tablet (25 mg) of ZAH was 1...

To achieve appropriate blood pressure control in the treatment of hypertension in Japan, this study examined the relationship between office blood pressure and actual antihypertensive drug use in general hospitals following the promulgation of the guidelines for hypertension (JSH2019). This study focused on blood pressure levels and drug use in outpatients on antihypertensive treatment from June to July 2020. The subjects were 2,537 patients classified into four groups based on their medical history, patients with: hypertension only; hypertension and cardiovascular disease; hypertension and dyslipidaemia; and hypertension and diabetes mellitus...

Medieval European medicine relied on monasteries where ancient medical works were transcribed. Trade routes to the East and the influence of Arab medicine, which supplemented the knowledge of Greco-Roman physicians, enabled the foundation and development of the Salerno Medical School, whose most famous work is Flos medicinae: Regimen sanitatis Salernitanum. This medical textbook, written in verse and drawn up on the basis of ancient sources and empirical experiences of Salerno physicians, contains rules on how to preserve health, on diseases and the use of medicinal plants for medicinal purposes...

Capecitabine is an anticancer agent and is the oral prodrug of 5-fluorouracil (5-FU). In this study, an ultra-high performance liquid chromatography coupled to turbo ion spray tandem mass spectrometry (UPLC-MS/MS) method was developed and validated to quantify capecitabine and its metabolites including 5'-deoxy-5-fluorocytidine (5'-dFCR), 5'-deoxy-5-fluorouridine (5'-dFUR), 5-FU, and fluoro-β-alanine (FBAL) in lithium heparinized human plasma. Analytes were extracted by protein precipitation, chromatographically separated by Acquity UPLC HSS T3 column with gradient elution, and analyzed with a tandem mass spectrometer equipped with an electrospray ionization source...
