Interindividual Variation in Source-Specific Doses is a Determinant of Health Impacts of Combined Chemical Exposures.

Risk analysis : an official publication of the Society for Risk Analysis

Price P.
PMID: 32671861
Risk Anal. 2020 Dec;40(12):2572-2583. doi: 10.1111/risa.13550. Epub 2020 Jul 15.

All individuals are exposed to multiple chemicals from multiple sources. These combined exposures are a concern because they may cause adverse effects that would not occur from an exposure recieved from any single source. Studies of combined chemical exposures,...

A Review of Recent Advances in Benchmark Dose Methodology.

Risk analysis : an official publication of the Society for Risk Analysis

Jensen SM, Kluxen FM, Ritz C.
PMID: 31046141
Risk Anal. 2019 Oct;39(10):2295-2315. doi: 10.1111/risa.13324. Epub 2019 May 02.

In this review, recent methodological developments for the benchmark dose (BMD) methodology are summarized. Specifically, we introduce the advances for the main steps in BMD derivation: selecting the procedure for defining a BMD from a predefined benchmark response (BMR),...

The use of epidemiological data in risk assessment.

Regulatory toxicology and pharmacology : RTP

Swaen GM.
PMID: 3222484
Regul Toxicol Pharmacol. 1988 Dec;8(4):422-30. doi: 10.1016/0273-2300(88)90041-4.

Next to toxicological data, epidemiological studies form the scientific basis for risk assessment. Both approaches have their particular advantages and limitations. The most important limitation of epidemiological studies is the lack of exact data on past exposures. Their most...

Is event-driven PrEP dosing for HIV as effective as daily dosing?.

The Journal of family practice

Olsen T, Lally-Montgomery Z, Kelsberg G, Safranek S, Neher J.
PMID: 34410919
J Fam Pract. 2021 Jun;70(5):253-255. doi: 10.12788/jfp.0207.

PROBABLY, although there are no head-to-head trials comparing the 2 dosing regimens. Event-driven pre-exposure prophylaxis (PrEP) dosing reduces HIV conversion by 86% compared to placebo (strength of recommendation [SOR]: B, large randomized controlled trial [RCT]). Daily PrEP reduces HIV...

J Sep Sci. 2021 Mar;44(5):945-953. doi: 10.1002/jssc.202001023. Epub 2021 Jan 18.

TQ-B3203 is a new topoisomerase I inhibitor derived from camptothecin. In this paper, a simple and reliable ultra high-performance liquid chromatography-tandem mass spectrometric method was developed and validated for determination of TQ-B3203 in human plasma with TQ-B3203-d

Similarities between the Yin/Yang Doctrine and Hormesis in Toxicology and Pharmacology.

Trends in pharmacological sciences

Sun H, Calabrese EJ, Lin Z, Lian B, Zhang X.
PMID: 32564900
Trends Pharmacol Sci. 2020 Aug;41(8):544-556. doi: 10.1016/j.tips.2020.05.004. Epub 2020 Jun 18.

Hormesis is a generalizable dose-response relationship characterized by low-dose stimulation and high-dose inhibition. Despite debate over this biphasic dose-response curve, hormesis is challenging central beliefs in the evaluation of chemicals or drugs and has influenced biological model selection, concentration...

Implementation of maximin efficient designs in dose-finding studies.

Pharmaceutical statistics

Fackle-Fornius E, Miller F, Nyquist H.
PMID: 25405333
Pharm Stat. 2015 Jan-Feb;14(1):63-73. doi: 10.1002/pst.1660. Epub 2014 Nov 18.

This paper considers the maximin approach for designing clinical studies. A maximin efficient design maximizes the smallest efficiency when compared with a standard design, as the parameters vary in a specified subset of the parameter space. To specify this...
