BACKGROUND: Gemcitabine-taxane combination chemotherapy has demonstrated a survival benefit clinically in metastatic pancreatic cancer (PC). The authors present their experience with gemcitabine and docetaxel (gem/tax)-based adjuvant treatment (Rx) after surgery with curative intent. METHODS: Patients with de novo resectable PC from January 2010 to December 2015 were identified from the authors' institutional database and registry. The study included only patients who received gem/tax as their initial Rx administered exclusively at the authors' institution with or without chemoradiation (CRTx)...

2'-C-cyano-2'-deoxy-1-β-D-arabino-pentofranocyl-cytosine (DFP-10917, CNDAC) is a 2'-deoxycytidine analog with antitumor activity against various tumor cells. However, a clinically available therapeutic regimen for this compound needs to be established and its functional mechanisms in relation to the dosing schedule need to be clarified. In this study, we evaluated the antitumor activity and toxicity of DFP-10917 by varying the dose and administration schedule in human solid tumor and leukemia xenografts in vivo...

The combined administration of nab-paclitaxel and gemcitabine (nab-P + Gem) is a standard chemotherapy for unresectable pancreatic ductal adenocarcinoma (UR-PDAC); thus, a predictive biomarker to identify patients best suited for nab-P + Gem therapy would be useful. Class III β-tubulin (TUBB3) has been reported to be a predictive marker for taxane resistance in various tumors. However, the correlation between TUBB3 expression and the response to nab-P + Gem in patients with UR-PDAC has not been evaluated. We retrospectively reviewed 75 patients with UR-PDAC who received nab-P + Gem...

BACKGROUND: Point-of-care blood gas test results may benefit therapeutic decision making by their immediate impact on patient care. We evaluated the (pre-)analytical performance of a novel cartridge-type blood gas analyzer, the GEM Premier 5000 (Werfen), for the determination of pH, partial carbon dioxide pressure (pCO2), partial oxygen pressure (pO2), sodium (Na+), potassium (K+), chloride (Cl-), ionized calcium (iCa2+), glucose, lactate, and total hemoglobin (tHb). METHODS: Total imprecision was estimated according to the CLSI EP5-A2 protocol...

Helicopter Emergency Medical Services (HEMS) is presumably an effective way of patient transport in rural trauma, yet the literature addressing its effectiveness is scarce. In this study, we compared the clinical outcome of rural trauma patients between Ground Emergency Medical Services (GEMS) and HEMS transportation from the beginning of 2006 to the end of 2012. Focus was placed on identifying factors associated with survival to discharge in these patients. Over the seven-year study period, 4492 patients met the inclusion criteria with 2414 patients (54%) being transferred by GEMS and 2078 patients (46%) being transferred by HEMS...

The Gleason scoring system is a key component of a prostate cancer diagnosis, since it indicates disease aggressiveness. It also serves as a risk communication tool that facilitates shared treatment decision-making. However, the system is highly complex and therefore difficult to communicate: factors which have been shown to undermine well-informed and high-quality shared treatment decision-making. To systematically explore prostate cancer patients' understanding of the Gleason scoring system (GSS), we assessed knowledge and perceived importance among men who had completed treatment (N = 50)...

Cp*Co(III)-catalyzed (Cp*=pentamethylcyclopentadienyl) C-H bond functionalization of 6-arylpurines using gem-difluoroalkenes and allyl fluorides is described. The reaction with gem-difluoroalkenes afforded monofluoroalkenes with high (Z)-selectivity, while the reaction with allyl fluorides led to C-H allylation in moderate (Z)-selectivity. Both reactions proceeded using a user-friendly single-component catalyst [Cp*Co(CH3CN)3](SbF6)2 in fluorinated alcohol solvents without any additives. Robustness was also demonstrated by a preparative-scale reaction under air...

BACKGROUND: Many low- and middle-income countries are reforming their health financing mechanisms as part of broader strategies to achieve universal health coverage (UHC). Voluntary social health insurance, despite evidence of resulting inequities, is attractive to policy makers as it generates additional funds for health, and provides access to a greater range of benefits for the formally employed. The South African government introduced a voluntary health insurance scheme (GEMS) for government employees in 2005 with the aim of improving access to care and extending health coverage...

BACKGROUND: Prostate-specific antigen (PSA) and PSA-velocity (PSAV) have been used to identify men at risk of prostate cancer (PrCa). The IMPACT study is evaluating PSA screening in men with a known genetic predisposition to PrCa due to BRCA1/2 mutations. This analysis evaluates the utility of PSA and PSAV for identifying PrCa and high-grade disease in this cohort. METHODS: PSAV was calculated using logistic regression to determine if PSA or PSAV predicted the result of prostate biopsy (PB) in men with elevated PSA values...

Several antimalarial drugs exist, but differences between life cycle stages among malaria species pose challenges for developing more effective therapies. To understand the diversity among stages and species, we reconstructed genome-scale models (GEMs) of metabolism for five life cycle stages and five species of Plasmodium spanning the blood, transmission, and mosquito stages. The stage-specific models of Plasmodium falciparum uncovered stage-dependent changes in central carbon metabolism and predicted potential targets that could affect several life cycle stages...

The OH radical is the most important radical in combustion and in the atmosphere, and methanol is a fuel and antifreeze additive, model biofuel, and trace atmospheric constituent. These reagents are also present in interstellar space. Here we calculate the rate constants, branching ratios, and kinetic isotope effects (KIEs) of the hydrogen abstraction reaction of methanol by OH radical in a broad temperature range of 30-2000 K, covering interstellar space, the atmosphere, and combustion by using the competitive canonical unified statistical (CCUS) model in both the low-pressure and high-pressure limits and, for comparison, the pre-equilibrium model...

BACKGROUND: It is well-known that genome sequencing technologies are becoming significantly cheaper and faster. As a result of this, the exponential growth in sequencing data in public databases allows us to explore ever growing large collections of genome sequences. However, it is less known that the majority of available sequenced genome sequences in public databases are not complete, drafts of varying qualities. We have calculated quality scores for around 100,000 bacterial genomes from all major genome repositories and put them in a fast and easy-to-use database...

Neurologic examination of the comatose patient has gradually matured. Less than 50 years ago, neurological examination in coma became a regular part of textbooks with separate chapters devoted to the topic but many were deficient in detail. In 1969, C.M. Fisher published an extraordinary 56-page paper on the examination of the comatose patient. The paper-one of Fisher's gems-is not well known and infrequently cited. The many new observations collected in this comprehensive paper are reviewed in this vignette, which highlights not only how these contributions shaped our thinking on coma but also questioned shaky concepts...

The combination of Pegylated Liposomal Doxorubicin (PLD) plus Gemcitabine (GEM) has been previously investigated in the treatment of metastatic breast cancer (MBC). PLD is a doxorubicin formulation with prolonged circulation time and better tissue distribution. GEM is a nucleoside analog with nonoverlapping toxicity compared to PLD. The aim of our study was to assess efficacy, toxicity, and long-term outcome of this combination. Patients with heavily treated MBC were retrospectively analyzed. Chemotherapy consisted of PLD 25 mg/m2 and GEM 800 mg/m2 day 1, on a three-week schedule...

A Rh(II)-catalyzed chemoselective oxidative amination and nucleophilic trapping of gem-dimethyl sulfamates has been presented. For 2,2-dimethyl-4-arylbut-3-yn-1-yl sulfamates, the reactions underwent a metallonitrene-initiated alkyne oxidation along with nucleophilic trapping of H2O upon oxidation, giving aroyl group containing heterocycles. For 2,2-dimethyl-4-arylpent-3-yn-1-yl sulfamates, the α-iminometal carbene intermediate was trapped by aryl group migration, delivering a styryl group containing heterocycles...

Low chemosensitivity considerably restricts the therapeutic efficacy of gemcitabine (GEM) in pancreatic cancer treatment. Using immunohistochemical evaluation, we investigated that decreased expression of human equilibrative nucleoside transporter-1 (hENT1, which is the major GEM transporter across cell membranes) and increased expression of ribonucleotide reductase subunit 2 (RRM2, which decreases the cytotoxicity of GEM) was associated with low GEM chemosensitivity. To solve these problems, we employed a nanomedicine-based formulation of cationic liposomes for co-delivery of GEM along with siRNA targeting RRM2...

BACKGROUND: The effect of prehospital helicopter emergency medical services (HEMS) on mortality has been analyzed previously in polytrauma patients with discordant results. OBJECTIVE: Our aim was to compare outcomes in patients with isolated severe blunt traumatic brain injuries (TBIs) transported by HEMS or ground emergency medical services (GEMS). METHODS: We conducted a National Trauma Data Bank study (2007-2014). All adult patients (≥16 years old) who sustained an isolated severe blunt TBI and were transported by HEMS or GEMS were included in the study...

The stability of gem-diol forms in imidazolecarboxaldehyde isomers was studied by solid-state nuclear magnetic resonance (ss-NMR) combined with single-crystal X-ray diffraction studies. These methodologies also allowed determining the factors governing the occurrence of such rare functionalization in carbonyl moieties. Results indicated that the position of the carbonyl group is the main factor that governs the generation of geminal diols, having a clear and direct effect on hydration, since, under the same experimental conditions, only 36% of 5-imidazolecarboxaldehydes and 5% of 4-imidazolecarboxaldehydes were hydrated, as compared to 2-imidazolecarboxaldehydes, with which a 100% hydration was achieved...
