Marlaine Figueroa Gray, Clarissa Hsu, Linda Kiel, Sascha Dublin
Objectives Gestational Diabetes Mellitus (GDM) affects hundreds of thousands of women each year. Many require medications to manage their blood glucose levels. Only insulin is approved by the U.S. Food and Drug Administration for use in pregnancy. While other medications can be used, their safety remains controversial. Few studies have examined women's lived experience of using insulin for GDM. Our objective in this study was to foreground the voices of women speaking about their treatment experience. Methods We conducted two focus groups including 16 women treated for GDM with medications, primarily insulin...

We present the case of a 62-year-old man with myelofibrosis-associated pulmonary arterial hypertension (PAH) who underwent allogeneic hematopoietic stem cell transplantation with subsequent resolution of disease and PAH. Right heart catheterization was used to guide PAH therapy before and after transplantation. Drug interactions, adverse effects, and renal insufficiency posed clinical challenges for the management of PAH-specific medications after transplantation. PAH improved soon after transplantation, and vasoactive medications were tapered off...

Natural products (NPs) research is changing and rapidly adopting cutting-edge tools, which radically transform the way to characterize extracts and small molecules. With the innovations in metabolomics, early integration of deep metabolome annotation information allows to efficiently guide the isolation of valuable NPs only and, in parallel, to generate massive metadata sets for the study of given extracts under various perspectives. This is the case for chemotaxonomy studies where common biosynthetic traits among species can be evidenced, but also for drug discovery purpose where such traits, in combination with bioactivity studies on extracts, may evidence bioactive molecules even before their isolation...

REVIEW
Cédric Rossi, René-Olivier Casasnovas
Classical Hodgkin lymphoma (HL) is a curable disease in 80% of advanced and 90% of localized stages. An improvement of the HL curability is still possible with the emergence of first-line therapy with a better balance between efficacy and toxicity and early identification patients with high risk of failure requiring specific treatment. 18FDG PET-CT gained a major role in the baseline staging and response assessment to HL treatment. The prognostic value of early PET-CT allowed to develop PET-CT guided therapies able to optimize the balance between efficacy and toxicity including the modulation of the chemotherapy intensity or the omission of radiotherapy for some localized diseases...

An EGF fragment and doxorubicin were chemically co-decorated on single magnetic nanoparticles for concomitant cancer targeting and treatment. Magnetic nanoparticles (MNPs) were prepared by the precipitation of ferric chloride hydrates in an ammonia solution and subsequent surface-functionalization with amines. The terminal thiol group of the EGF fragment (EGFfr) was first conjugated to surface amines of the MNPs using a heterofunctional crosslinker, and doxorubicin was sequentially conjugated to the MNPs via a hydrazone linker, where the degree of substation of the surface amines to EGF was varied from 1% to 40%...

Adamantanes such as amantadine (1) and rimantadine (2) are FDA-approved anti-influenza drugs that act by inhibiting the wild-type M2 proton channel from influenza A viruses, thereby inhibiting the uncoating of the virus. Although adamantanes have been successfully used for more than four decades, their efficacy was curtailed by emerging drug resistance. Among the limited number of M2 mutants that confer amantadine resistance, the M2-V27A mutant was found to be the predominant mutant under drug selection pressure, thereby representing a high profile antiviral drug target...

ADB-CHMINACA (MAB-CHMINACA) is a new synthetic cannabinoid with high potency and many reported adverse events and fatalities. The drug is currently scheduled in several countries in Europe and the USA. Analytical methods need to be developed to confirm ADB-CHMINACA intake for clinical and forensic programs. For many synthetic cannabinoids, parent compound is not detectable in biological samples after intake, making the detection of metabolites the only way to prove consumption. Therefore, detection of ADB-CHMINACA metabolites in biological specimens is critical...

The development of a technology capable of tracking the levels of drugs, metabolites, and biomarkers in the body continuously and in real time would advance our understanding of health and our ability to detect and treat disease. It would, for example, enable therapies guided by high-resolution, patient-specific pharmacokinetics (including feedback-controlled drug delivery), opening new dimensions in personalized medicine. In response, we demonstrate here the ability of electrochemical aptamer-based (E-AB) sensors to support continuous, real-time, multihour measurements when emplaced directly in the circulatory systems of living animals...

Hearing loss and nephrotoxicity are associated with prolonged treatment duration and higher dosage of amikacin and kanamycin. In our Tuberculosis Center, we have employed therapeutic drug monitoring (TDM) targeting pre-set pharmacokinetic/pharmacodynamic (PK/PD) surrogate endpoints in an attempt to maintain efficacy while preventing (oto-)toxicity. To evaluate this strategy, we retrospectively evaluated medical charts of TB patients treated with amikacin or kanamycin in the period 2000 - 2012.Patients with culture-confirmed multi- or extensively drug resistant tuberculosis (MDR/XDR-TB) receiving amikacin or kanamycin as part of their TB treatment for at least 3 days were eligible for inclusion in this retrospective study...
