REVIEW
Parli R Ravi, Bipin Puri
This brief update reviews the recent literature available on fluid resuscitation from hemorrhagic shock and considers the applicability of this evidence for use in resuscitation of combat casualties in the combat casualty care (CCC) environment. A number of changes need to be incorporated in the CCC guidelines: (1) dried plasma (DP) is added as an option when other blood components or whole blood are not available; (2) the wording is clarified to emphasize that Hetastarch is a less desirable option than whole blood, blood components, or DP and should be used only when these preferred options are not available; (3) the use of blood products in certain tactical field care settings where this option might be feasible (FSC, GH) is discussed; (4) 1:1:1 damage control resuscitation (DCR) with plasma: packed red blood cells (PRBC): platelets is preferred to 1:1 DCR with plasma: PRBC when platelets are available; and (5) the 30-min wait between increments of resuscitation fluid administered to achieve clinical improvement or target blood pressure has been eliminated...

Specific mutations in epidermal growth factor receptor (EGFR) gene are predictive for response to the EGFR tyrosine kinase inhibitors (TKIs) in non-small cell lung cancer patients (NSCLC). According to international guidelines, the molecular testing in patients with advanced NSCLC of a non-squamous subtype is recommended. However, obtain a tissue sample could be challenging. Liquid biopsy allows to determine patients suitable for EGFR-targeted therapy by analysis of circulating-free tumor DNA (cfDNA) in peripheral blood samples and might replace tissue biopsy...

We investigated the hypothesis that the increased concentration of plasma methylguanidine (MG) increases oxidative metabolism and accelerates apoptosis of neutrophils from dogs with chronic kidney disease (CKD). To achieve this, the levels of MG were quantified in healthy (n=16) and uremic dogs with CKD stage 4 of according to the guidelines of the International Renal Interest Society (IRIS, 2015) (n=16) using high performance liquid chromatography (HPLC). To evaluate the isolated effect of MG on neutrophil oxidative metabolism and apoptosis, neutrophils isolated from 12 healthy dogs were incubated with the highest concentration of plasma MG (0...

BACKGROUND: The resuscitation of severely injured bleeding patients has evolved into a multi-modal strategy termed damage control resuscitation (DCR). This guideline evaluates several aspects of DCR including the role of massive transfusion (MT) protocols, the optimal target ratio of plasma (PLAS) and platelets (PLT) to red blood cells (RBC) during DCR, and the role of recombinant activated factor VII (rVIIa) and tranexamic acid (TXA). METHODS: Using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology, a subcommittee of the Practice Management Guidelines (PMG) Section of EAST conducted a systematic review using MEDLINE and EMBASE...

OBJECTIVES: Two nucleos(t)ide reverse-transcriptase inhibitors (NRTIs) plus 1 non-NRTI (nNRTI) remain the preferred or alternative combination antiretroviral therapy (cART) for antiretroviral-naive HIV-positive patients in Taiwan. The three most commonly used nNRTIs are nevirapine (NVP), efavirenz (EFV) and rilpivirine (RPV). This study aimed to determine the incidences of hepatotoxicity and skin rashes within 4 weeks of initiation of cART containing 1 nNRTI plus 2 NRTIs. METHODS: Between June, 2012 and November, 2015, all antiretroviral-naive HIV-positive adult patients initiating nNRTI-containing cART at 8 designated hospitals for HIV care were included in this retrospective observational study...

BACKGROUND: All recent treatment guidelines recommend integrase strand transfer inhibitors (INSTIs) as components of initial HIV therapy. Bictegravir, a novel, once-daily, unboosted INSTI, showed potent activity in a 10 day monotherapy study and has a high in-vitro resistance barrier. On the basis of these results, we did a phase 2 trial comparing bictegravir with dolutegravir. METHODS: In this randomised, double-blind, phase 2 trial, we recruited previously untreated adults (aged ≥18 years) with HIV-1 infections from 22 outpatient centres in the USA...

OBJECTIVE: Circulating microparticles (cMPs) are phospholipid-rich vesicles released from cells when activated or injured, and contribute to the formation of intracoronary thrombi. Tissue factor (TF, CD142) is the main trigger of fibrin formation and TF-carrying cMPs are considered one of the most procoagulant cMPs. Similar types of atherosclerotic lesions may lead to different types of AMI, although the mechanisms behind are unresolved. Therefore, we aimed to investigate the phenotype of cMPs found in plasma of ACS patients and its relation to AMI severity and thrombotic burden...

Multiple myeloma (MM) is caused by the neoplastic proliferation of plasma cells. These neoplastic plasma cells proliferate and produce monoclonal immunoglobulin in the bone marrow causing skeletal damage, a hallmark of multiple myeloma. Other MM-related complications include hypercalcemia, renal insufficiency, anemia, and infections. The NCCN Multiple Myeloma Panel members have developed guidelines for the management of patients with various plasma cell dyscrasias, including solitary plasmacytoma, smoldering myeloma, multiple myeloma, systemic light chain amyloidosis, and Waldenström's macroglobulinemia...

Tenofovir alafenamide is a new oral prodrug of tenofovir resulting in relatively low plasma levels and rapid uptake into peripheral blood mononuclear cells in its active form. The United States Food and Drug Administration has now approved this drug coformulated with elvitegravir/cobicistat/emtricitabine, rilpivirine/emtricitabine and emtricitabine. United States guidelines now list this formulation as one of the preferred components of a variety of antiretroviral regimens, and is included as an alternative in other international guidelines, with the notable exception of the World Health Organization, mostly due to limited availability...

Understanding arsenic speciation in water is important for managing the potential health risks associated with chronic arsenic exposure. Most arsenic monitoring studies to date have only measured total arsenic, with few looking at arsenic species. This study assessed 228 ground water sources in six unstudied villages in Pakistan for total, inorganic and organic arsenic species using ion chromatography inductively coupled plasma collision reaction cell mass spectrometry. The concentration levels approached 3090μgL(-1) (95% CI, 130...

Fresh frozen plasma (FFP) is widely used by anesthetists and/or intensivists managing bleeding patients. In this context, two clinical situations with different benefit/risk ratio for FFP transfusion should be distinguished: moderate or controlled hemorrhage on one side, and massive hemorrhage on the other. In the former situation, administration of FFP is most often ineffective, associated with potential side effects (pulmonary complications, product shortage) and should therefore be restricted. In case of massive hemorrhage, transfusion of FFP, red blood cells and platelets using a ratio close to 1:1:1 is recommended based on a large number of studies...

Waldenström macroglobulinaemia (WM) is an indolent B-cell malignancy characterised by the presence of immunoglobulin M (IgM) paraprotein and bone marrow infiltration by clonal small B lymphocytes, plasmacytoid lymphocytes and plasma cells. The symptoms of WM are protean, often follow an asymptomatic phase and may include complications related to the paraneoplastic effects of IgM paraprotein. The revised 2016 World Health Organization classification includes the MYD88 L265P mutation, which is seen in >90% of cases, within the diagnostic criteria for WM...
