Watermarking appears as a promising tool for the traceability of shared medical databases as it allows hiding the traceability information into the database itself. However, it is necessary to ensure that the distortion resulting from this process does not hinder subsequent data analysis. In this paper, we present the preliminary results of a study on the impact of watermarking in the estimation of flu activities. These results show that flu epidemics periods can be estimated without significant perturbation even when considering a moderate watermark distortion...

Glands in frog skin secrete substances that possess broad antimicrobial function. Holthausen et al. mined this soup of natural products and discovered a peptide that destroys diverse human influenza strains (Holthausen et al., 2017). This study points the way to the discovery of novel anti-influenza molecules targeting conserved elements on influenza surface proteins.

Core body temperature (CBT) is an important and commonly used indicator of human health and endurance performance. A rise in baseline CBT can be attributed to an onset of flu, infection or even thermoregulatory failure when it becomes excessive. Sites which have been used for measurement of CBT include the pulmonary artery, the esophagus, the rectum and the tympanic membrane. Among them, the tympanic membrane is an attractive measurement site for CBT due to its unobtrusive nature and ease of measurement facilitated, especially when continuous CBT measurements are needed for monitoring such as during military, occupational and sporting settings...

Seasonal respiratory illnesses present a major burden on primary care services. We assessed the burden of respiratory illness on a national telehealth system in England and investigated the potential for providing early warning of respiratory infection. We compared weekly laboratory reports for respiratory pathogens with telehealth calls (NHS 111) between week 40 in 2013 and week 29 in 2015. Multiple linear regression was used to identify which pathogens had a significant association with respiratory calls...

Background &Aims: Sofosbuvir is a powerful drug for treatment of hepatitis C virus (HCV) infection. In comparison to preceding remedies, sofosbuvir-based regimens provide a higher cure rate, fewer side effects, and much lower duration of treatment. The aim of the work was to assess the efficacy and safety of sofosbuvir plus ribavirin with or without peginterferon-alfa in treatment of a cohort of Egyptian patients with hepatitis C virus infection. METHODS: Two hundred treatment naive patients who were HCV-antibody positive and HCV RNA by PCR positive aged more than 18 years were enrolled in the study and patients were classified into two groups: Group I which included 100 patients who received dual therapy with sofosbuvir plus oral weight based ribavirin and Group II which included 100 patients triple therapy with sofosbuvir plus oral weight based ribavirin (as with the dual therapy) and a 180 mcg Peg-INF alpha 2a subcutaneous injection weekly for 12 weeks...

Nucleic-acid-based drugs are a promising class of novel therapeutics; however, their use in medicine is widely limited because of insufficient delivery into cells. This article proposes a new delivery strategy of nucleic acid fragments into cells as components of TiO2-based nanocomposites. For the first time, unmodified Dz molecules were non-covalently immobilized on TiO2 nanoparticles precovered with polylysine (TiO2•PL) with the formation of (TiO2•PL)•Dz nanocomposites. DNAzymes in the proposed nanocomposites were shown to retain their ability to cleave the RNA target in a cell-free system with the same selectivity as unbound Dz molecules...

Myeloid-derived suppressor cells (MDSCs) accumulate in tumor-bearing hosts and play a key role in the suppression of the innate and adaptive immunity. Chemotherapeutic strategies have been developed to deplete or deactivate MDSCs in different tumor models. The pyrimidine analog, 5-fluorouracil (5-FU) is found to reduce the tumor size by depleting MDSCs. Here, we asked whether the purine analog, fludarabine (Flu), could exert similar effects. Employing a lymphoma model, we demonstrated that in mice with advanced tumors (where MDSC-induced suppression was present), treatment with a single low-dose Flu (25, 50, 100mg/kg) elevated the numbers of splenic MDSCs and serum arginase activity, and simultaneously, increased the tumor growth (only the highest dose)...

Transitioning CD19-directed CAR-T cells from early phase trials in relapsed patients to a viable therapeutic approach with predictable efficacy and low toxicity for broad application in patients with high unmet need is currently complicated by product heterogeneity resulting from transduction of undefined T cell mixtures, variability of transgene expression, and terminal differentiation of cells at the end of culture. A phase 1 trial of 45 children and young adults with relapsed or refractory B-lineage ALL was conducted using a CD19 CAR product of defined CD4/CD8 composition, uniform CAR expression, and limited effector differentiation...

REVIEW
Nicole L Davis, Caroline C King, Athena P Kourtis
Cytomegalovirus (CMV) is a DNA herpesvirus that is common worldwide. The two known main sources of primary CMV infection during pregnancy are through sexual activity and contact with young children. Primary infection occurs in approximately 1 to 4% of pregnancies, and is mostly asymptomatic in immunocompetent adults. However, primary infection may manifest as a mild mononucleosis or flu-like syndrome with persistent fever and fatigue. CMV can be transmitted from mother-to-child in utero, intrapartum, or during breastfeeding...

Background/Aims A single best endpoint for evaluating treatments of severe influenza requiring hospitalization has not been identified. A novel six-category ordinal endpoint of patient status is being used in a randomized controlled trial (FLU-Intravenous Immunoglobulin - FLU-IVIG) of intravenous immunoglobulin. We systematically examine four factors regarding the use of this ordinal endpoint that may affect power from fitting a proportional odds model: (1) deviations from the proportional odds assumption which result in the same overall treatment effect as specified in the FLU-IVIG protocol and which result in a diminished overall treatment effect, (2) deviations from the distribution of the placebo group assumed in the FLU-IVIG design, (3) the effect of patient misclassification among the six categories, and (4) the number of categories of the ordinal endpoint...

Lei Han, Yu Zhang, Xiu-Feng Wan, Tong Zhang
Recent statistical evidence has shown that a regression model by incorporating the interactions among the original covariates/features can significantly improve the interpretability for biological data. One major challenge is the exponentially expanded feature space when adding high-order feature interactions to the model. To tackle the huge dimensionality, hierarchical sparse models (HSM) are developed by enforcing sparsity under heredity structures in the interactions among the covariates. However, existing methods only consider pairwise interactions, making the discovery of important high-order interactions a non-trivial open problem...

BACKGROUND: The inappropriate use of antimicrobials is a problem worldwide. To target future interventions, a thorough understanding of the reasons behind this current behaviour is needed. Within the EU, the culture of antimicrobial use has been intensely studied, but this is not the case in non-EU southeastern European countries, despite the frequent use of (broad-spectrum) antibiotics (ABs) in this region. The aim of this study was to explore AB knowledge, attitudes and behaviours of health care professionals (HCPs) and patients in one southeastern European country, Albania...

BACKGROUND: Dendritic cells (DCs) enhance the quality of anti-tumor immune response in patients with cancer. Thus, we posit that DC-based immunotherapy, in conjunction with toll-like receptor (TLR)-3 agonist poly-ICLC, is a promising approach for harnessing immunity against metastatic or locally advanced unresectable pancreatic cancer (PC). METHODS: We generated autologous DCs from the peripheral blood of HLA-A2(+) patients with PC. DCs were pulsed with three distinct A2-restricted peptides: 1) human telomerase reverse transcriptase (hTERT, TERT572Y), 2) carcinoembryonic antigen (CEA; Cap1-6D), and 3) survivin (SRV...

Bronchiolitis obliterans with organizing pneumonia is an inflammatory reaction that can occur as a consequence of various pulmonary affections. Radiotherapy is not the sole and systematic cause of bronchiolitis obliterans with organizing pneumonia. Radiation-induced should not be confused with post-radiation, dose-dependent, inflammatory pulmonary fibrosis, which is non-immunological and located within the irradiation field. The role of immunity, local inflammation and individual radiosensitivity in bronchiolitis obliterans with organizing pneumonia is not well defined...

BACKGROUND: In Europe, flu remains one of the major public health problems. Healthcare workers (HCWs) are a category at high-risk of contracting the infection and infecting their patients; consequently, for this category, vaccination is highly recommended. Unfortuntely, coverage levels remain insufficient with rates ranging between 4 and 40. STUDY DESIGN: The purpose of our work was to evaluate the adherence of HCWs to the influenza vaccination and to carry out a combination of educational and motivational interventions in order to increase the rate of adherence to the vaccination in this workers' category...
