Antitumor immunity relies on the ability of the immune system to recognize tumor cells as foreign and eliminate them. An effective immune response in this setting is due to surveillance of tumor-specific antigens that induce an adaptive immune response resulting in T-cell mediated cytotoxicity. Immune checkpoint inhibitors, specifically those targeting the programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) axis, have demonstrated promising activity in non-small cell lung cancer (NSCLC). However, there remains a crucial need for better treatment strategies for the majority of patients with advanced NSCLC, particularly in the frontline setting...

BACKGROUND: Men diagnosed with localized prostate cancer must make a choice between treatment strategies that differ considerably in their side effects and have different long-term requirements for coping with the disease. The aim of this study was to describe how men perceive their treatment decision retrospectively and which coping strategies they use. MATERIAL & METHODS: Fifteen men (age mean=67.13±9.38 years) diagnosed with localized prostate cancer participated in three focus groups, grouped according to the treatment strategies radical prostatectomy, radiotherapy, and active surveillance...

Introduction: The purpose of this study was to explore the association of smoking status and clinically relevant duration of smoking cessation with long-term survival after lung cancer (LC) or colorectal cancer (CRC) diagnosis. We compared survival of patients with LC and CRC who were never-smokers, long-term, medium-term, and short-term quitters, and current smokers around diagnosis. Methods: We studied 5,575 patients in Cancer Care Outcomes Research and Surveillance (CanCORS), a national, prospective observational cohort study, who provided smoking status information approximately 5 months after LC or CRC diagnosis...

BACKGROUND: The importance of influenza viruses in respiratory infections in sub-Saharan Africa has been historically overlooked, including in Burkina Faso. This study therefore aimed at evaluating the prevalence and seasonal occurrence of influenza viruses in children under five years old, at risk of influenza-related complications, presenting with influenza-like illness (ILI) or severe acute respiratory infection (SARI). The study also aimed at identifying the periods with increased influenza transmission for vaccination recommendations in Burkina Faso...

CXCR4 is a 7-transmembrane receptor expressed by hematopoietic stem cells and progeny, as well as by ≥ 48 different cancers types. CXCL12, the only chemokine ligand of CXCR4, is secreted within the tumor microenvironment, providing sanctuary for CXCR4+ tumor cells from immune surveillance and chemotherapeutic elimination by 1) stimulating pro-survival signaling and 2) recruiting CXCR4+ immunosuppressive leukocytes. Additionally, distant CXCL12-rich niches attract and support CXCR4+ metastatic growths. Accordingly, CXCR4 antagonists can potentially obstruct CXCR4-mediated pro-survival signaling, recondition the CXCR4+ leukocyte infiltrate from immunosuppressive to immunoreactive, and inhibit CXCR4+ cancer cell metastasis...

PURPOSE: The United States has no comprehensive national surveillance system for fatal or nonfatal child agricultural injuries. Thus, important knowledge gaps exist about recurrent injury patterns that could provide targeted focus for prevention efforts. The purpose of this study was to explore existing US public health data systems to determine their utility with respect to informing child agricultural injury surveillance and primary prevention. METHODS: Public health data systems were selected if they: (1) were national in scope, (2) were active and ongoing, (3) included physical injuries, and (4) contained a "farm" location variable...

OBJECTIVES: In a polio-free world there might be reduced funding for poliovirus surveillance. There is therefore the need to ensure that enterovirologist globally, especially those outside the global polio laboratory network, can participate in poliovirus surveillance without neglecting their enterovirus type of interest. To accomplish this, assays are needed that allow such active participation. RESULTS: In this study we describes a sensitive and specific utility extension of the recently recommended WHO RT-snPCR assay that enables independent detection of the three poliovirus types especially in cases of co-infection...

We investigate three aspects of the importance of nodes with respect to susceptible-infectious-removed (SIR) disease dynamics: influence maximization (the expected outbreak size given a set of seed nodes), the effect of vaccination (how much deleting nodes would reduce the expected outbreak size), and sentinel surveillance (how early an outbreak could be detected with sensors at a set of nodes). We calculate the exact expressions of these quantities, as functions of the SIR parameters, for all connected graphs of three to seven nodes...

Madry et al. (2018) show that the two-pore potassium channel TWIK-1 is tonically active in microglia and promotes microglial ramification and surveillance of the brain parenchyma. Interestingly, THIK-1 is not essential to damage-induced outgrowth of microglial processes but is critical to microglial IL-1β release.

PROBLEM/CONDITION: Preconception health is a broad term that encompasses the overall health of nonpregnant women during their reproductive years (defined here as aged 18-44 years). Improvement of both birth outcomes and the woman's health occurs when preconception health is optimized. Improving preconception health before and between pregnancies is critical for reducing maternal and infant mortality and pregnancy-related complications. The National Preconception Health and Health Care Initiative's Surveillance and Research work group suggests ten prioritized indicators that states can use to monitor programs or activities for improving the preconception health status of women of reproductive age...

We review the evidence that supports cardiorespiratory fitness (CRF) as an important indicator of current and future health among school-aged children and youth, independent of physical activity levels. We discuss the merit of CRF measurement for population health surveillance and propose the development of CRF guidelines to help support regional, national, and international surveillance efforts.

Prevalence of health behaviors among adults with disabilities may vary by disability measure. We used data from the 2011-2015 National Health Interview Survey to estimate prevalence of physical inactivity by disability status using 2 measures of disability: Basic Actions Difficulty questions (BADQ) and a standard 6-question measure (6Q). Disability prevalence (BADQ, 31.1%; 6Q, 17.5%) and inactivity prevalence among adults with disability (BADQ, 42.9%; 6Q, 52.5%) and without disability (BADQ, 24.3%; 6Q, 26.2%) varied by measure; however, both measures highlight inactivity disparities for adults with disability...

To investigate the association between the incidence of human brucellosis (HB) and adverse pregnancy outcomes (APOs), a population-based, cross-sectional aggregate data study was conducted in Israel between 2010 and 2014. HB-endemic localities were matched by ethnicity, population size and socioeconomic status to localities with a low incidence of HB. We compared APO rates in high-incidence vs low-incidence localities. The primary outcome was intrauterine fetal demise (IUFD). Secondary outcomes were premature birth (less than 37 weeks), early or threatened labour and poor fetal growth...

There has been tremendous progress in detection of breast cancer in postmenopausal women, resulting in two-thirds of women surviving more than 20 years after treatment. However, breast cancer remains the leading cause of cancer-related deaths in premenopausal women. Breast cancer is increasing in younger women due to changes in life-style as well as those at high risk as carriers of mutations in high-penetrance genes. Premenopausal women with breast cancer are more likely to be diagnosed with aggressive tumours and therefore have a lower survival rate...
