The clinical data gathered validates their use as surrogate markers, exhibiting high specificity and reproducibility. The genotypes of drug transporters, in conjunction with systemic exposure to perpetrator drugs, influence the pharmacokinetic parameters of endogenous biomarkers. The development of physiologically-based pharmacokinetic models for endogenous biomarkers has promoted a top-down perspective for understanding the effects of perpetrators on drug transporters and more accurately simulating drug-drug interactions with victim drugs, encompassing probe medications. To address uncertainty in DDI predictions in the preclinical and early clinical development stages, endogenous biomarkers hold promise for potentially fulfilling regulatory requirements. Consequently, endogenous biomarkers ought to be capable of forecasting the disease’s impact on the fluctuations in drug transporter activity, as seen in patient cases. This mini-review presents a synopsis of recent progress in identifying and applying endogenous drug transporter substrate biomarkers to improve drug development strategies. Advances in analytical methods have facilitated the identification of endogenous substrates that are constituents of drug transporter systems. foxm1 signals receptor During clinical trials, drug-drug interaction predictions can be refined using changes in endogenous biomarker pharmacokinetic parameters (Cmax, AUC, or CLR) in relation to their baseline values, a quantitative measure of drug transporter activity variations.

Pharmacokinetic modeling in pediatric drug development, guided by physiological principles, has progressed significantly over the last decade, but there remain open questions about the developmental origins of some drug-metabolizing enzymes. This study utilized a physiologically based pharmacokinetic (PBPK) model for midazolam and 1-hydroxymidazolam to establish the developmental progression of hepatic cytochrome P450 (CYP) 3A4 and uridine diphosphate glucuronosyl transferase (UGT) 2B4. Intravenous midazolam’s pharmacokinetic data, spanning adult and pediatric demographics, was synthesized from the literature to serve as the foundation for subsequent modeling and research. Adult validation of the PBPK model preceded its use to compare the effectiveness of two CYP3A4 ontogeny profiles in predicting parent drug elimination characteristics within the pediatric population. Four research papers presented data on 1-hydroxymidazolam, which was then employed to examine the developmental trajectory of UGT2B4. Regarding 1-hydroxymidazolam elimination, the Simcyp default UGT2B4 ontogeny performed optimally for studies including individuals aged 5 to 157 years, while for research focusing on very young subjects aged 0 to 1 year, the Badee UGT2B4 ontogeny proved to be more appropriate. A well-defined CYP3A4 ontogeny model is needed for the proper use of PBPK in regulatory contexts. While midazolam results are definitive, further investigation into other CYP3A4 substrates is crucial to establishing the general applicability of the CYP3A4 ontogeny model. Concerning the ontogeny of UGT2B4, there is some ambiguity; nonetheless, this study indicates the most plausible developmental pathways. The creation of a PBPK model for midazolam and 1-hydroxymidazolam was driven by the need to test a multitude of ontogeny scenarios for CYP3A4 and UGT2B4. More accurate midazolam clearance predictions, spanning nine clinical studies, were achieved through the characterization of Upreti’s CYP3A4 ontogeny, covering patients from birth to 18 years old. The presence of 1-hydroxy midazolam indicated UGT status. The Simcyp default ‘no ontogeny’ profiles for UGT2B4 proved the most effective; however, under one year of age, a pattern of potentially elevated activity for this enzyme was detected in contrast to the adult enzyme activity.

This research delved into families’ coping strategies and stress responses during the trying times of the COVID-19 pandemic.

In the USA, a qualitative study took place within the paediatric outpatient clinics of a large academic medical center, encompassing the months from March to July of 2021.

Those parents of children under 18 years of age, and who are themselves over 18 years old, were invited to a 30-minute semi-structured interview.

The COVID-19 pandemic served as a context for participants to discuss the stressors they faced and the coping strategies they utilized. All interviewees’ voices were audio-recorded and meticulously transcribed. Employing thematic analysis, the transcripts were examined according to the grounded theory perspective.

In a study involving interviews with 26 participants, 88% (n=23) identified as women, 85% (n=22) had children under 10 years old, and 65% (n=17) were aged 30-50. Participants’ narratives revolved around the magnified burden of COVID-19-related stress, stemming from multiple concurrent pressures. Regarding employment, a parent highlighted that they held down two different positions, whereas the employment opportunity they relied on was lost due to the COVID-19 pandemic. Working from home, with the added responsibility of children, presented an overwhelming amount of stress. The second theme explored the problems virtual schooling posed for children, which were directly linked to the decrease in educational support available. The need for parental self-care was highlighted as the third key theme. Unforeseen opportunities for resilience and family bonding emerged as silver linings, as parents noted these during the fourth theme, focused on spending time in nature and engaging in related activities.

Parents voiced a desire for self-care, fostering relationships with their children, and appreciating the tranquility of natural surroundings. Ongoing research should prioritize the creation of frameworks to help families cope with intricate difficulties, especially during pandemic-related hardships or similar crises.

Parents expressed a need for self-care, creating special moments with their children, and finding peace within the embrace of nature’s beauty. Future endeavors must investigate supportive strategies for families coping with complex hardships, particularly during crises such as pandemics or other emergencies.

The risk of pre-eclampsia, a major cause of maternal and perinatal mortality and morbidity worldwide, is heightened by inadequate dietary calcium consumption. Calcium supplementation, in women experiencing low dietary calcium intake, could potentially prevent the occurrence of pre-eclampsia. Even so, the perfect dosage and schedule for taking calcium supplements remain unspecified. To determine the effectiveness of different calcium supplementation protocols in preventing pre-eclampsia and its complications, we propose to perform a meta-analysis using individual participant data (IPD) from randomized trials, followed by ranking. A further objective is to investigate the cost-benefit relationship of calcium supplementation in preventing the occurrence of pre-eclampsia.

Randomized trials addressing calcium supplementation use in the pre-pregnancy and pregnancy phases will be discovered by meticulously exploring major electronic databases, such as Embase, CINAHL, MEDLINE, CENTRAL, PubMed, Scopus, AMED, LILACS, POPLINE, AIM, IMSEAR, and ClinicalTrials.gov. The WHO International Clinical Trials Registry Platform, accepting submissions from all languages, was in operation from its commencement to February 2022. Investigators of the chosen trials will be invited to affiliate with the International Calcium in Pregnancy Collaborative Network and provide their individual patient data. Before any standardization or harmonization, the IPD of each study will be examined for its consistency with the data presented by the original authors. To estimate the overall intervention effects on pre-eclampsia with 95% confidence intervals and explore treatment-covariate interactions (maternal risk status, dietary intake, intervention timing, calcium dose, and total calcium intake), we will employ one-stage and two-stage IPD random-effects meta-analyses. Heterogeneity will be summarized with the parameter tau.
