Abstract
Endocrine-disrupting chemicals (EDC) are compounds that alter functions of the endocrine system due to their ability to mimic or antagonize endogenous hormones, or that alter their synthesis and metabolism, causing adverse health effects. Human biomonitoring (HBM) is a reliable method to assess human exposure to chemicals through measurement in human body fluids and tissues. It identifies new sources of exposure and determines their distribution, thereby enabling detection of the most exposed populations. Blood and urine are commonly used for HBM of EDC, but their interest is limited for compounds presenting short half-lives. Hair appears as an interesting alternative insofar as it provides a large exposure window. For the present study, we evaluated the relevance of hair in determining EDC exposure. With this in mind, we undertook a literature review focusing on the bioanalytical aspects and performances of methods developed to determine EDC in hair. The literature review was performed through methodical bibliographical research. Relevant articles were identified using two scientific databases: PubMed and Web of Science, with search equations built from a combination of keywords, MeSH terms and Boolean operators. The search strategy identified 2949 articles. After duplicates were removed, and following title, abstract, and full-text screenings, only 31 were included for qualitative synthesis. Hair collection was mainly performed in the back of the head and preparation involved two processes: cutting into small pieces or grounding to powder. The off-line LC-MS/MS method remains the main technique used to assess EDC through hair. Differences regarding the validation of analytical methods and interpretation of HBM results were highlighted, suggesting a need for international harmonisation to obtain reliable and comparable results. External contamination of hair was identified as a main limitation in the interpretation of results, highlighting the need to better understand EDC transfers through hair and to develop relevant hair decontamination processes.

Abstract
BACKGROUND Crushing or dissolving bictegravir/tenofovir alafenamide/emtricitabine (BIC/TAF/FTC) tablets is not recommended because there are no data supporting this practice. METHODS A crossover, randomized trial in healthy adults (NCT04244448) investigated the bioavailability of two off-label uses of BIC/TAF/FTC (50/200/25 mg), dissolved in water or crushed in apple compote, compared with the solid tablet. Pharmacokinetic (PK) parameters were estimated from sequential intensive plasma antiretroviral concentrations over a 72 h period post dose. Bioequivalence was met if the 90% CIs of the geometric least-squares means ratios comparing BIC/TAF/FTC exposures (AUC and Cmax) from the experimental phases were within 80%-125% of the reference. RESULTS Eighteen subjects participated in each of the three phases. Dissolved tablet Cmax geometric mean ratio (90% CI) for BIC/TAF/FTC was 105% (93-119)/97% (87-108)/96% (74-124), respectively. Dissolved tablet AUC geometric mean ratio (90% CI) for BIC/TAF/FTC was 111% (100-122)/100% (94 to 105)/99% (81 to 120), respectively. Crushed tablet Cmax geometric mean ratio (90%) CI for BIC/TAF/FTC was 110% (97 to 124)/70% (63-78)/66% (51-85), respectively. Crushed tablet AUC geometric mean ratio (90%) CI for BIC/TAF/FTC was 107% (96-118)/86% (82-91)/84% (69-103), respectively. CONCLUSIONS Crushing BIC/TAF/FTC tablets may lead to suboptimal emtricitabine and tenofovir alafenamide drug exposures. Dissolving BIC/TAF/FTC in water may be acceptable if the tablet cannot be swallowed whole.

Abstract
PURPOSE The increasing burden of invasive fungal infections results in growing challenges to antifungal (AF) therapeutic drug monitoring (TDM). This review aims to provide an overview of recent advances in AF TDM. METHODS We conducted a PubMed search for articles during 2016-2020 using "TDM" or "pharmacokinetics" or "drug-drug-interaction" with "antifungal," consolidated for each AF. Selection was limited to English language articles with human data on drug exposure. RESULTS More than 1000 articles matched the search terms. We selected 566 publications. The latest findings tend to confirm previous observations in real-life clinical settings. The pharmacokinetic variability related to special populations is not specific but must be considered. AF benefit-to-risk ratio, drug-drug interaction (DDI) profiles, and minimal inhibitory concentrations for pathogens must be known to manage at-risk situations and patients. Itraconazole has replaced ketoconazole in healthy volunteers DDI studies. Physiologically based pharmacokinetic modeling is widely used to assess metabolic azole DDI. AF prophylactic use was studied more for Aspergillus spp. and Mucorales in oncohematology and solid organ transplantation than for Candida (already studied). Emergence of central nervous system infection and severe infections in immunocompetent individuals both merit special attention. TDM is more challenging for azoles than amphotericin B and echinocandins. Fewer TDM requirements exist for fluconazole and isavuconazole (ISZ); however, ISZ is frequently used in clinical situations in which TDM is recommended. Voriconazole remains the most challenging of the AF, with toxicity limiting high-dose treatments. Moreover, alternative treatments (posaconazole tablets, ISZ) are now available. CONCLUSIONS TDM seems to be crucial for curative and/or long-term maintenance treatment in highly variable patients. TDM poses fewer cost issues than the drugs themselves or subsequent treatment issues. The integration of clinical pharmacology into multidisciplinary management is now increasingly seen as a part of patient care.

Abstract
Entecavir treatment failure can be observed in compliant patients despite an absence of detectable resistance mutations by Pol/RT Sanger sequencing. We hypothesized that these unexplained treatment failures could rely on other mechanisms of viral resistance, especially on mutations selected outside of the Pol/RT domain. Partial virological response to entecavir was observed in three patients treated with immunosuppressive drugs, without selection of Pol/RT resistance mutations. Mutations selected in the whole HBV genome during entecavir treatment and potentially associated with resistance were searched for using deep sequencing and characterized using a phenotypic resistance assay. Mutations Q206K (pre-core/core), Q120K (pre-S1/pre-S2, T-cell epitope) and A300E (spacer domain) were selected during entecavir treatment in patient #1 but were not associated with an increased level of resistance to entecavir or an increase in HBV replication capacity. Core promoter mutations T1753G, A1762T and G1764A were present as major mutations before and after treatment in patient #1. HBs Ag immune escape mutations were present as major mutations before and after treatment in patients #2 (sK122R, sT126I, sP127S and sG145R) and #3 (sM133I). We demonstrated that PVR to entecavir does not require selection of any resistance mutation in the whole HBV genome. Our results demonstrate that major mutations can be selected outside of the Pol/RT domain before or during entecavir treatment. These mutations could contribute to entecavir treatment failure by other mechanisms than an increased level of resistance.

Abstract
Urinary catecholamines and their methylated metabolites are biochemical indicators of pheochromocytoma, paraganglioma and neuroblastoma. A rapid and precise analytical method based on solid-phase extraction (SPE) and liquid chromatography separation coupled to high-resolution mass spectrometry (LC-HRMS) was developed and validated to measure urinary catecholamines (epinephrine (E), norepinephrine (NorE), dopamine (D)) and total methylated metabolites (normetanephrine (NorMN), metanephrine(MN) and 3-methoxytyramine (3-MT)) in a clinical setting. Results of 51 urine specimens measured using this LC-HRMS method were compared with a liquid chromatography assay with electrochemical detection (LC-EC). Urine samples (200 μL) were spiked with an internal standard solution followed by SPE purification. In the case of total methylated metabolites, urine was hydrolyzed before SPE purification. Separation was achieved on an Acclaim Mixed Mode WCX column, with an 8.5 min runtime. All compounds were detected in electrospray positive ionization mode with a parallel reaction monitoring acquisition and quantified with a linear regression (r2 > 0.998) between 2 and 200 µg/L (10.9-1090; 11.8-1182 nmol/L) for E and NorE respectively and between 10 and 1000 µg/L for others (65.2-6520; 50.7-5070; 54.5-5450 ; 59.8-5980 nmol/L for D, M, NorMN and 3-MT, respectively). Overall imprecision and bias did not exceed 15%. No significant matrix effect was observed. Correlation between the two assays was good except for epinephrine. Epinephrine concentrations measured by LC-EC method were slightly higher than values obtained with LC-HRMS method but without impact on clinical decision. This LC-HRMS assay provides a new tool for simultaneous quantitative catecholamine determination and was successfully applied in routine for the screening or follow up of pheochromocytoma, paraganglioma and neuroblastoma. LC-HRMS method offers significant advantages compared to LC-EC with good sensitivity, an unambiguous analyte determination and high sample throughput.

Abstract
BACKGROUND Increasingly, people living with human immunodeficiency virus (HIV) benefit from lower drug regimens (LDRs). Exploring viral genital shedding during LDRs is crucial to ensure their safety. METHODS We pooled genital sub-studies from 2 clinical trials in this area. Patients were randomized 1:1 to continue abacavir/lamivudine/dolutegravir or switch to dolutegravir (MONCAY trial), or to continue tenofovir/emtricitabine + a third agent or switch to tenofovir/emtricitabine (TRULIGHT trial). Participants whose plasma HIV-RNA remained <50 copies/mL had sperm or cervicovaginal lavage collected between Weeks 24 and 48. HIV-RNA and HIV-DNA were amplified by ultrasensitive polymerase chain reaction. The main objective was to measure the proportion of participants who had no detectable HIV in genital fluids, both according to each strategy and then in an aggregated analysis (LDR versus triple therapies). RESULTS There were 64 participants (35 males, 29 females) included: 16 received dual therapies and 16 received triple therapies in TRULIGHT; and 16 received monotherapies and 16 received triple therapies in MONCAY. In TRULIGHT, 13/15 (87%) of evaluable participants on dual therapy had no detectable HIV in their genital fluid, versus 14/15 (93%) under triple therapy (P = 1.0). In MONCAY, these figures were 12/15 (80%) on monotherapy versus 13/16 (81%) on triple therapy (P = 1.0). In the pooled analysis, a similar proportion of participants in the LDR and triple therapy groups had no detectable HIV: 25/30 (83%) and 27/31 (87%), respectively (P = .73). CONCLUSIONS There was no evidence of increased HIV-RNA and/or -DNA shedding in the genital fluids of people who maintained undetectable plasma HIV-RNA during LDRs. CLINICAL TRIALS REGISTRATION NCT02302547 and NCT02596334.

Abstract
The use of antibacterial drugs is very common in critically ill patients and beta-lactam agents are widely used in this context. Critically ill patients show several characteristics (e.g., sepsis, renal impairment or conversely augmented renal clearance, renal replacement therapy) that may alter beta-lactam pharmacokinetics (PK) in comparison with non-critically ill patients. This narrative literature review aims to identify recent studies quantifying the variability of beta-lactams volume of distribution and clearance and to determine its main determinants. Seventy studies published between 2000 and 2018 were retained. Data on volume of distribution and clearance variability were reported for 5 penicillins, 3 beta-lactamase inhibitors, 6 cephalosporins and 4 carbapenems. Data confirm specific changes in PK parameters and important variability of beta-lactam PK in critically ill patients. Renal function, body weight and use of renal replacement therapy are the principal factors influencing PK parameters described in this population. Few studies have directly compared beta-lactam PK in critically ill versus non-critically ill patients. Conclusions are also limited by small study size and sparse PK data in several studies. These results suggest approaches to assess this PK variability in clinical practice. Beta-lactam therapeutic drug monitoring seems to be the best way to deal with this issue.

Abstract
BACKGROUND Beta-lactam antibiotics (βLA) are the most commonly used antibiotics in the intensive care unit (ICU). ICU patients present many pathophysiological features that cause pharmacokinetic (PK) and pharmacodynamic (PD) specificities, leading to the risk of underdosage. The French Society of Pharmacology and Therapeutics (SFPT) and the French Society of Anaesthesia and Intensive Care Medicine (SFAR) have joined forces to provide guidelines on the optimization of beta-lactam treatment in ICU patients. METHODS A consensus committee of 18 experts from the two societies had the mission of producing these guidelines. The entire process was conducted independently of any industry funding. A list of questions formulated according to the PICO model (Population, Intervention, Comparison, and Outcomes) was drawn-up by the experts. Then, two bibliographic experts analysed the literature published since January 2000 using predefined keywords according to PRISMA recommendations. The quality of the data identified from the literature was assessed using the GRADE® methodology. Due to the lack of powerful studies having used mortality as main judgement criteria, it was decided, before drafting the recommendations, to formulate only "optional" recommendations. RESULTS After two rounds of rating and one amendment, a strong agreement was reached by the SFPT-SFAR guideline panel for 21 optional recommendations and a recapitulative algorithm for care covering four areas: (i) pharmacokinetic variability, (ii) PK-PD relationship, (iii) administration modalities, and (iv) therapeutic drug monitoring (TDM). The most important recommendations regarding βLA administration in ICU patients concerned (i) the consideration of the many sources of PK variability in this population; (ii) the definition of free plasma concentration between four and eight times the Minimal Inhibitory Concentration (MIC) of the causative bacteria for 100% of the dosing interval as PK-PD target to maximize bacteriological and clinical responses; (iii) the use of continuous or prolonged administration of βLA in the most severe patients, in case of high MIC bacteria and in case of lower respiratory tract infection to improve clinical cure; and (iv) the use of TDM to improve PK-PD target achievement. CONCLUSIONS The experts strongly suggest the use of personalized dosing, continuous or prolonged infusion and therapeutic drug monitoring when administering βLA in critically ill patients.

Abstract
Antibiotic (ATB) treatment of critically ill patients with pathophysiological injuries remains a challenge due to the constant increase in antimicrobial resistance. Therapeutic drug monitoring (TDM) is advised for ATB dose adjustments to avoid suboptimal concentrations and dose-related adverse effects. Therefore, a single and reliable analytical method for a broad selection of ATBs was developed using a high-resolution mass spectrometry (HRMS) platform for frequent use in intensive care units. An UHPLC assay coupled to high resolution accurate mass acquisition has been developed for the quantification of penicillins (amoxicillin, oxacillin, piperacillin, and ticarcillin), cephalosporines (cefepime, cefotaxime, ceftazidime, and ceftriaxone), carbapenems (ertapenem, imipenem, and meropenem), lincosamide (clindamycin), quinolones (ofloxacin and ciprofloxacin) and tazobactam. Plasma samples (100μL) were spiked with an internal standard solution followed by protein precipitation. Separation was achieved on an Accucore C18 column, which enabled sample analysis every 9min. All compounds were detected in electrospray positive ion mode and quantified with a linear regression between 0.5 and 32mg/L (r2>0.998). Overall precision and accuracy did not exceed 15%. No significant matrix effect was observed for the studied ATBs. Stored stock solutions at -20°C were stable for 6 months, except for amoxicillin and imipenem. Analytes in plasma were stable for 24h under ambient conditions as well as in post-preparation in an autosampler, except for amoxicillin and imipenem. This HRMS assay provides the simultaneous quantification of 15 ATB; it fulfills the usual quality criteria and was successfully applied for routine TDM of ATBs. The method is based on a full scan acquisition, and it would be easy to add other compounds to the present panel in the future, as this assay has already been proven to be efficient for different classes of compounds.

Abstract
Posaconazole, systemic antifungal marketed in France since 2006, is indicated as second line in curative treatment of invasive fungal infections (IFI) (aspergillosis. . . ) and prophylaxis of IFI in patients receiving chemotherapy or hematopoietic stem cell transplantation. The analysis of the literature indicates a concentration-efficacy relationship, but to date, no study has been able to show a concentration-toxicity correlation due to its favourable safety profile and the difficulty to obtain high concentrations. In curative, maintenance of trough plasma concentrations between 0.5 and 1.5 mg/L seems to be associate with an efficacy. In prophylaxis, a threshold of 0.5 mg/L corresponds to a minimal exposure. However this target is not yet well defined. Saturation of absorption above the 800 mg oral dose limits the adjustment of concentrations. As such, the Therapeutic Drug Monitoring of posaconazole can be recommended.

Abstract
BACKGROUND Fragile X Syndrome (FXS) is the most common form of inherited intellectual disability and is also associated with autism spectrum disorders. Previous studies implicated BKCa channels in the neuropathogenesis of FXS, but the main question was whether pharmacological BKCa stimulation would be able to rescue FXS neurobehavioral phenotypes. METHODS AND RESULTS We used a selective BKCa channel opener molecule (BMS-204352) to address this issue in Fmr1 KO mice, modeling the FXS pathophysiology. In vitro, acute BMS-204352 treatment (10 μM) restored the abnormal dendritic spine phenotype. In vivo, a single injection of BMS-204352 (2 mg/kg) rescued the hippocampal glutamate homeostasis and the behavioral phenotype. Indeed, disturbances in social recognition and interaction, non-social anxiety, and spatial memory were corrected by BMS-204352 in Fmr1 KO mice. CONCLUSION These results demonstrate that the BKCa channel is a new therapeutic target for FXS. We show that BMS-204352 rescues a broad spectrum of behavioral impairments (social, emotional and cognitive) in an animal model of FXS. This pharmacological molecule might open new ways for FXS therapy.

Abstract
The prevention and treatment of pediatric fungal infections are limited by the fact that not all antifungal drugs are approved for the pediatric age and appropriate dosages have not been established for each age group. The management of neonates and infants with invasive fungal infection is becoming more complex with an increasing number of antifungal agents available. Dosing information, is not available for newer antifungals and is limited with older antifungal agents. Insufficient neonatal studies have been performed with newer agents and there are numerous differences between neonates, children and adults with invasive fungal infection. Kinetic parameters such as the half-life [t(½)], clearance [CL], and volume of distribution [Vd] change with development, therefore the kinetics of antifungals need to be studied in order to optimize therapy with these drugs. A reasonable aim of pediatric dosing is to ensure levels of drug exposure which are comparable to those achievable in adults and which approximate those for which antifungal efficacy has been established. Therefore it will be of clinical relevance to ascertain the dosages of antifungals which produce an equivalent magnitude of exposure to that observed in adults. Drug therapy, studies on prescription and dosing should consider differences between neonates, infants and toddlers, children and adolescents in terms of drug disposition: absorption, metabolism and elimination/excretion. Determining the safety and pharmacokinetics of antifungals in neonates addresses an unfulfilled medical need given that data are sparse in neonates; at present, reports of antifungal pharmacokinetics in the treatment of neonatal fungal infections are limited to case series. The aim of this article is to review the pharmacokinetics of old and new antifungal drugs in neonates and young infants in a single article in order to provide a critical analysis of the literature. It will be important to evaluate all newly developed antifungals in neonates and infants to assure their maximum efficacy and safety. More pharmacokinetic data are required to ensure that the dose recommended for the treatment of fungal infections in the neonate achieves evidence based medicine.

Abstract
BACKGROUND AND OBJECTIVES A microdialysis study of meropenem distribution in the peritoneal fluid of patients with peritonitis has suggested that there is significant peripheral drug degradation. The aims of the present study were to investigate the plasma and peritoneal fluid pharmacokinetics of imipenem, a relatively unstable antibacterial, in patients with severe peritonitis, and to relate measured unbound concentrations to the minimum inhibitory concentrations required for susceptible and intermediately susceptible bacteria. METHODS Microdialysis catheters were placed into the peritoneal cavity through peritoneal drains in nine critically patients. Imipenem concentrations in plasma and in peritoneal fluid were analysed using compartmental modelling. RESULTS A model that considered elimination from a peripheral compartment described the data and was used to simulate steady-state concentration profiles in plasma and peritoneal fluid during various dosing regimens. Using recommended dosing regimens (500 mg every 6 hours, 1000 mg every 8 hours and 1000 mg every 6 hours), simulated unbound peritoneal fluid concentrations of imipenem in patients with severe peritonitis reached values sufficient for antibacterial effects against susceptible bacteria. However, the adequacy of regimens in patients with severe peritonitis whose infections involve intermediately susceptible bacteria is questionable. CONCLUSION The results of this study are consistent with those previously observed with meropenem and confirm the usefulness of microdialysis for assessment of peritoneal fluid distribution of antibacterials.

Abstract
OBJECTIVES The combination of non-opioid analgesic drugs (P: paracetamol, K: ketoprofen and N: nefopam) is currently recommended for postoperative pain control. In practice, these analgesics are often administered in the same solution. We investigated the chemical stability and sterility of three mixtures of analgesics (P+K, P+N and K+N). METHODS For each mixture, concentrations of active principles were measured using high-performance liquid chromatography over 24 hours. These mixtures were cultured for microbiological colonization. RESULTS Our study demonstrated chemical and bacteriologic stability of these three mixtures over a 24-hour period. The results allow the use of P+K, P+N and K+N in the same ready to use solution.

Abstract
Our objective was to describe the pharmacokinetics of meropenem in the peritoneal fluid (PF) of six patients with severe peritonitis and septic shock and to relate measured concentrations to the minimum inhibitory concentration of bacteria. Microdialysis catheters were placed into the peritoneal space during surgery. Meropenem concentrations in plasma and in PF were analyzed using compartmental modeling. Meropenem areas under the concentration-time curve were lower in PF than in plasma (average ratio, 73.8+/-15%) because of degradation confirmed ex vivo. Compartment modeling with elimination from a peripheral compartment described the data adequately, and was used to simulate steady-state concentration profiles in plasma and PF during various dosing regimens. At the currently recommended dosing regimen of 1 g infused over 20 min every 8 h, PF concentrations of meropenem in patients with severe peritonitis associated with septic shock reach values sufficient for antibacterial effects against susceptible, but not always against intermediately susceptible, bacteria.

Abstract
The purpose of this study was to extend the use of microdialysis to the investigation of antibiotic distribution into the intraperitoneal fluid of rats with or without peritonitis. Microdialysis probes were inserted into the jugular vein and peritoneal cavity of control rats or rats with intra-abdominal sepsis (n = 8 in each group) induced by cecal ligation and punctures. Imipenem (IPM) probe recoveries were determined in each rat by retrodialysis by drug. IPM was infused intravenously at a dose of 30 mg . kg(-1) over 30 min, microdialysis samples were collected for 120 min, and IPM concentrations were determined by high-performance liquid chromatography. Intraperitoneal infection had no statistically significant effect on IPM clearance (11.9 +/- 2.3 ml.min(-1).kg(-1) in control rats versus 10.9 +/- 2.1 ml.min(-1).kg(-1) in rats with peritonitis) or the volume of distribution (296 +/- 47 ml.kg(-1) in control rats versus 310 +/- 49 ml.kg(-1) in rats with peritonitis). IPM concentration profiles in intraperitoneal fluid and blood were virtually superimposed in control rats, whereas in infected animals, the mean intraperitoneal IPM concentrations were apparently slightly lower than corresponding blood levels. However, the areas under the concentration-versus-time curve estimated in intraperitoneal fluid and blood were not significantly different in both groups, with the corresponding ratios close to unity (1.01 +/- 0.19 and 0.89 +/- 0.28 in control rats and rats with peritonitis, respectively). In conclusion, IPM distribution in intraperitoneal fluid is rapid and complete both in control rats and in rats with peritonitis.
