Article Abstract
Monoclonal antibodies (mAbs) have been extensively developed over the past few years, for the treatment of various inflammatory diseases. They are large molecules characterized by complex pharmacokinetic and pharmacodynamic properties. Therapeutic drug monitoring (TDM) is routinely implemented in the therapy with mAbs, to monitor patients' treatment response and to further guide dose adjustments. Serum has been the matrix of choice in the TDM of mAbs and its sampling requires the visit of the patients to laboratories that are not always easily accessible. Therefore, dried blood spots (DBS) and various microsampling techniques have been suggested as an alternative. DBS is a sampling technique in which capillary blood is deposited on a special filter paper. It is a relatively simple procedure, and the patients can perform the home-sampling. The convenience it offers has enabled its use in the quantification of small-molecule drugs, whilst in the recent years, studies aimed to develop microsampling methods that will facilitate the TDM of mAbs. Nevertheless, hematocrit still remains an obstacle that hinders a more widespread implementation of DBS in clinical practice. The introduction of novel analytical techniques and contemporary microsampling devices can be considered the steppingstone to the attempts made addressing this issue.

Background: Existing longitudinal cohort study data and associated biospecimen libraries provide abundant opportunities to efficiently examine new hypotheses through retrospective specimen testing. Outcome-dependent sampling (ODS) methods offer a powerful alternative to random sampling when testing all available specimens is not feasible or biospecimen preservation is desired. For repeated binary outcomes, a common ODS approach is to extend the case-control framework to the longitudinal setting.

Alzheimer's Disease (AD) is the leading cause of dementia worldwide, with significant cognitive and behavioural impairments that devastate individuals and their families. Cohort-level findings, demonstrate the broader population-level implications of Sleep and Circadian Rhythm Disruption (SCRD) in AD and underscore the need for early interventions, emphasizing the importance of timely action. However, the mechanism remains unclear.

Background: Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, significantly impact patients' lives. Effective management often involves invasive and costly monitoring.
Objective: To evaluate the feasibility of integrating home-based fecal calprotectin testing with therapeutic drug monitoring (TDM) in managing moderate-to-severe IBD.
Medications for Opioid Use Disorder in County Jails - Outcomes after Release.

Background: In 2019, seven county correctional facilities (jails) in Massachusetts initiated pilot programs to provide all Food and Drug Administration-approved medications for opioid use disorder (MOUD).
Methods: This observational study used linked state data to examine postrelease MOUD receipt, overdose, death, and reincarceration among persons with probable opioid use disorder (OUD) in carceral settings who did or did not receive MOUD from these programs from September 1, 2019, through December 31, 2020. Log-binomial and proportional-hazards models were adjusted for propensity-score weights and baseline covariates that remained imbalanced after propensity-score weighting.
