まとめ
環境要因によって誘発される敏感肌は、高齢女性における色素沈着やしわなどの皮膚老化の兆候と関連している。本研究は、敏感肌のサブタイプと特定の老化パターンとの関連性を強調する。
科学分野:
- 皮膚科
- 化粧品科学
- Epidemiology
背景:
- 敏感肌は、無害な刺激による不快な感覚を伴い、病態生理は不明確であるが、環境要因やバリア機能障害と関連している。
- 敏感肌を引き起こす環境ストレス因子は、外因性の皮膚老化も引き起こし、潜在的な関連性を示唆している。
- 以前の研究では、敏感肌と皮膚老化表現型との関連性が提案されていたが、大規模な客観的データが不足していた。
研究 の 目的:
- 敏感肌のサブタイプと特定の皮膚老化表現型との関連性を調査する。
- 敏感肌と皮膚老化の客観的指標との潜在的な関連性を大規模コホートで特定する。
- 敏感肌のサブタイプが、特に高齢者集団において、異なる老化パターンと相関するかどうかを検討する。
主な方法:
- 中国泰州縦断研究(2012-2014年)の810人の参加者からのデータを分析した。
- 質問票の回答に基づいて敏感肌をサブタイプに分類した。
- SCINEXA(Score of Intrinsic and Extrinsic Skin Aging)基準と多変量回帰モデルを用いて皮膚老化表現型を評価した。
主要な成果:
- 環境要因によって誘発される敏感肌は、50歳以上の参加者、特に女性において、頬の色素沈着と有意な関連を示した。内因的に誘発される敏感肌は、口囲のしわと関連しており、高齢女性でより顕著な効果が観察された。本研究は、敏感肌のサブタイプと特定の皮膚老化表現型との客観的な関連性を初めて大規模に実証した。
結論:
- 本研究結果は、敏感肌のサブタイプと明確な皮膚老化の現れとの相関関係を実証した。
- 特定の敏感肌表現型は、環境ストレス因子や老化に対する感受性が高い亜集団を示す可能性がある。
- 敏感肌とその関連する老化の影響に対する標的化された予防および管理戦略が正当化される。

The Effect of Aging on Tissues
3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Aging

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Absorption
208
As individuals age, their body's physiology evolves, affecting drug pharmacokinetics. The most apparent changes occur in the gastrointestinal tract, where an increase in gastric pH, a delay in gastric emptying, and a reduction in gastrointestinal motility are observed. Remarkably, these changes do not substantially modify the absorption of orally administered drugs, particularly those absorbed via passive diffusion.Transdermal drug delivery emerges as a highly viable method for older adults due...

Pharmacodynamics in Geriatric Patients: Effects of Age

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Changes in Skin Color: Clinical Perspectives
3.2K
The first thing a clinician sees is the skin, so the examination of the skin should be part of any thorough physical examination. Most skin disorders are relatively benign, but a few, including melanomas, can be fatal if untreated. A couple of the more noticeable disorders, albinism and vitiligo, affect the appearance of the skin and its accessory organs.

Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Distribution
215
Drug distribution in the human body is influenced by several factors, including plasma protein concentration, body composition, blood flow, tissue-protein concentration, and tissue fluid pH. Among these, changes in plasma protein concentration and body composition due to aging significantly affect how drugs are distributed within the body. Specifically, aging is associated with a decrease in albumin levels by about 10% and an increase in α1-acid glycoprotein levels. These alterations are...
