Japan Geriatrics Society "Statement for the use of telemedicine in geriatric care: Telemedicine as a complement to in-person medical practice": Geriatric Medical Practice Committee consensus statement.

Telemedicine has changed from a way to treat patients with limited access to hospitals to a necessary method of treatment for non-urgent conditions during the coronavirus disease 2019 pandemic. There are two styles of telemedicine, namely "hybrid medical care" and "gateway medical care," which take advantage of the characteristics of online medical care and might become important in the near future. During hybrid medical care, a patient and their primary care physician have face-to-face medical care while simultaneously being examined by a specialist physician through telemedicine, leading to an overall improvement in the level of local medical care and expansion in the number of treatable diseases.

Indomethacin, a Non-steroidal Anti-inflammatory Drug, Induces Skin Dryness via PPARγ in Mice.

Cyclooxygenase (COX)-1-selective inhibitors have side effects such as itching and dryness of the skin. In this study, the degree of skin dryness and the onset mechanism of this condition were investigated by comparing the effects of three non-steroidal anti-inflammatory drugs (NSAIDs) in mice. Mice were orally administered either indomethacin, loxoprofen sodium, or celecoxib (n = 5 per group) once daily for four consecutive days, and blood samples as well as skin and jejunal tissues were isolated on day 5.

Onset Mechanism and Pharmaceutical Management of Dry Skin.

Dry skin is a common symptom of various conditions, and elderly individuals commonly exhibit this physiological symptom. Dry skin develops owing to sebum deficiency; however, the use of moisturizers can typically overcome this issue, particularly in patients in whom there are no other skin problems. If dry skin is left untreated, itching and eczema can occur, resulting in skin damage.

High-Dose Vitamin C Exerts Its Anti-cancer Effects in a Xenograft Model of Colon Cancer by Suppressing Angiogenesis.

Several studies have been conducted to investigate the anti-cancer effects of vitamin C (VC). However, the effect of high-dose VC administration on tumor angiogenesis remains unclear. Focusing on our high-dose VC, our study investigated the effect of high-dose VC (4 g/kg) on vascular endothelial growth in mice with xenografts of a rectal cancer cell line referred to as Colon 26.

Differences in the mechanism of type 1 and type 2 diabetes-induced skin dryness by using model mice.

Diabetes induces dry skin that may cause infective diseases. In this study, we aimed to clarify the mechanism of diabetes-induced skin dryness in animal models. We also examined the difference in the mechanism of skin dryness in type 1 and type 2 diabetes.

Carbon Monoxide Rescues the Developmental Lethality of Experimental Rat Models of Rhabdomyolysis-Induced Acute Kidney Injury.

Many victims, after being extricated from a collapsed building as the result of a disaster, suffer from disaster nephrology, a term that is referred to as the crush syndrome (CS). Recommended treatments, which include dialysis or the continuous administration of massive amounts of fluid are not usually easy in cases of such mass natural disasters. In the present study, we examined the therapeutic performance of a biomimetic carbon monoxide (CO) delivery system, CO-enriched red blood cells (CO-RBCs), on experimental animal models of an acute kidney injury (AKI) induced by traumatic and nontraumatic rhabdomyolysis, including CS and rhabdomyolysis with massive hemorrhage shock.

Risk factor analysis of the decrease in gait speed among Japanese older outpatients with polypharmacy.

Background: Both polypharmacy and frailty are critical issues faced by the elderly. The decrease in gait speed is an index of frailty, and it is generally associated with falls and fractures, which are risk factors requiring the need for support or long-term patient care. In this study, we assess the risk factors responsible for the decrease in gait speed in older outpatients with polypharmacy.

[Protection of the Skin Barrier Function in Inflammatory Disease].

The skin is the largest human organ, comprising the epidermis that is composed of epithelial tissue, the dermis composed of connective tissue, and the innermost subcutaneous tissue. Generally, skin conditions are due to aging and the influence of the external environment, but empirically patients with gastrointestinal diseases are more prone to pruritus and inflammation caused by dry skin. A decrease in the skin barrier function, involving immunocompetent mast cells and oxidative stress, was noted in indomethacin-induced small intestine inflammation, dextran sodium sulfate (DSS)-induced ulcerative colitis, and azoxymethane+DSS-induced colorectal cancer.

[Evaluation of a pharmacist-led intervention on polypharmacy].

Aim: In order to ensure that patients use medicines and dressings properly, the pharmacist must understand a patient's medication history, symptoms, and test results. This information helps pharmacists to apply their technical knowledge to the prescription of drugs. In Japan, more than a quarter of the population is over 65 years of age; the country is heading toward a "super-aged" society.
