Mean and variance of greenness and pregnancy outcomes in Tel Aviv during 2000-14: longitudinal and cross-sectional approaches.

Background Natural environments may have beneficial impacts on pregnancy outcomes. However, longitudinal evidence is limited and the associations with variance in surrounding greenness is unknown. Our objective was to evaluate these associations among 73 221 live births in Tel Aviv, Israel. Methods Longitudinal exposure to mean of greenness during pregnancy and trimesters were calculated using satellite-based Moderate Resolution Imaging Spectroradiometer (MODIS) Normalised Difference Vegetation Index (NDVI) data. In addition, exposure to mean and variation of NDVI from high-resolution satellite and percentage of tree cover [Vegetation Continuous Fields (VCF)] at 300-m buffer were evaluated in a cross-sectional approach. Generalized linear models were used to estimate the crude and adjusted associations. We explore the possible mediating role of ambient exposures and distance to 'outdoor gyms' located in parks. Results Crude beneficial associations between exposure to higher mean NDVI during pregnancy and pregnancy outcomes were observed [for birthweight, 3rd/1st tertile exposure increased the mean by 25.5 g, 95% confidence intervals (CIs): 15.4, 35.5] and decreased the odds of low birthweight, small for gestational age, preterm deliveries (PTD) and very PTD. Adjustment for individual and neighbourhood-level markers of socio-economic status (SES) attenuated all the associations. Strongest associations were observed during the first and second trimesters. Cross-sectional associations for mean greenness were similar with narrower CIs, and associations with NDVI were stronger than with tree cover and stronger for mean compared with variance of greenness. Associations were consistent for term births, different buffer sizes and for further adjustment to maternal education. Stronger associations were observed for lowest SES. Distance to 'outdoor gyms' and variance of greenness had the largest estimates of mediation. Conclusion This study adds to the limited information on when exposure to greenness is most beneficial, on the association with variance of greenness and the possible pathways. These observations require confirmation in other populations.
Ancient Ancestry Informative Markers for Identifying Fine-Scale Ancient Population Structure in Eurasians

The rapid accumulation of ancient human genomes from various areas and time periods potentially allows the expansion of studies of biodiversity, biogeography, forensics, population history, and epidemiology into past populations. However, most ancient DNA (aDNA) data were generated through microarrays designed for modern-day populations known to misrepresent the population structure. Past studies addressed these problems using ancestry informative markers (AIMs). However, it is unclear whether AIMs derived from contemporary human genomes can capture ancient population structure and whether AIM finding methods are applicable to ancient DNA (aDNA) provided that the high missingness rates in ancient, oftentimes haploid, DNA can also distort the population structure. Here, we define ancient AIMs (aAIMs) and develop a framework to evaluate established and novel AIM-finding methods in identifying the most informative markers. We show that aAIMs identified by a novel principal component analysis (PCA)-based method outperforms all competing methods in classifying ancient individuals into populations and identifying admixed individuals. In some cases, predictions made using the aAIMs were more accurate than those made with a complete marker set. We discuss the features of the ancient Eurasian population structure and strategies to identify aAIMs. This work informs the design of population microarrays and the interpretation of aDNA results.
Virotherapy-recruited PMN-MDSC infiltration of mesothelioma blocks antitumor CTL by IL-10-mediated dendritic cell suppression

ABSTRACT Antitumor cytotoxic T lymphocytes (CTLs) are essential for immune surveillance, yet the blockade of eliciting such CTLs during oncolytic virotherapy remains incompletely understood. Here, we show that oncolysis of mesothelioma by modified vaccinia Tiantan (MVTT) induces damage-associated molecular patterns exposure. Although MVTT leads to regression of established mesothelioma dose-dependently, antitumor CTLs are rarely induced. Mechanistically, MVTT virotherapy generates C-X-C chemokines that recruit CXCR2-expressing polymorphonuclear myeloid-derived suppressor cells (PMN-MDSCs) into tumor microenvironment, where they suppress dendritic cells (DCs) by producing IL-10 and halt CTL responses. During the virotherapy, however, depletion of PMN-MDSCs but not of monocytic (M)-MDSCs results in the induction of potent antitumor CTLs that not only eradicate established mesothelioma but also prevent the second tumor challenge. Our findings suggest that vaccinia virotherapy may combine strategies that prevent the chemotactic recruitment of PMN-MDSCs, block their suppression on DCs or deplete PMN-MDSCs in order to induce potent CTLs for tumor eradication.
Calcium Intake and Survival after Colorectal Cancer Diagnosis

Purpose: Although evidence suggests an inverse association between calcium intake and colorectal cancer incidence, the influence of calcium on survival after colorectal cancer diagnosis remains unclear. Experimental Design: We prospectively assessed the association of postdiagnostic calcium intake with colorectal cancer–specific and overall mortality among 1,660 nonmetastatic colorectal cancer patients within the Nurses' Health Study and the Health Professionals Follow-up Study. Patients completed a validated food frequency questionnaire between 6 months and 4 years after diagnosis and were followed up for death. Multivariable hazard ratios (HRs) and 95% confidence intervals (95% CI) were calculated using Cox proportional hazards regression. Results: Comparing the highest with the lowest quartile intake of postdiagnostic total calcium, the multivariable HRs were 0.56 (95% CI, 0.32–0.96; P trend = 0.04) for colorectal cancer–specific mortality and 0.80 (95% CI, 0.59–1.09; P trend = 0.11) for all-cause mortality. Postdiagnostic supplemental calcium intake was also inversely associated with colorectal cancer–specific mortality (HR, 0.67; 95% CI, 0.42–1.06; P trend = 0.047) and all-cause mortality (HR, 0.71; 95% CI, 0.54–0.94; P trend = 0.008), although these inverse associations were primarily observed in women. In addition, calcium from diet or dairy sources was associated with lower risk in men. Conclusions: Higher calcium intake after the diagnosis may be associated with a lower risk of death among patients with colorectal cancer. If confirmed, these findings may provide support for the nutritional recommendations of maintaining sufficient calcium intake among colorectal cancer survivors.
Maintenance rituximab for relapsing thrombotic thrombocytopenic purpura: a case report

Appropriate management to prevent relapses of acquired, autoimmune thrombotic thrombocytopenic purpura (TTP) is not clear. Rituximab (375 mg/m2/week × 4) is effective treatment for acute episodes but it is not consistently effective for prevention of relapses. Maintenance rituximab, 375 mg/m2/3 months for 2 years, is commonly used to prevent progression of follicular lymphoma, but the outcome of maintenance rituximab to prevent TTP relapses has been rarely reported.
Survey of patients of the Tver region of Russia regarding maggots and maggot therapy

The 21st century is seeing a resurgence in the use of maggot therapy—using the physical and biochemical benefits of fly larvae to debride and heal chronic, problematic wounds. Maggots are repulsive to many people, and this could interfere with the acceptance of this modality. Before instituting a maggot therapy programme at our institution, we sought to better understand the psychological barriers that may exist among patients in the Tver region of Russia. Between 2014 and 2016, all patients with arterial insufficiency and trophic ulcers at City Clinical Hospital No. 7 in Tver were administered a survey consisting of six images. Subjects were asked to rank the images in the order of least to most repulsive or disgusting. A total of 576 subjects were recruited for this study: 414 (72%) women and 162 (28%) men. Nearly 60% of subjects considered the images of maggots to be more repulsive than images of gangrenous wounds. This finding is significant because it indicates that much education and support will need to be conducted to address patient fears and anxiety if patients are to be comfortable with a maggot therapy programme.
Converging phenomics and genomics to study natural variation in plant photosynthetic efficiency

Summary In recent years developments in plant phenomic approaches and facilities have gradually caught up with genomic approaches. An opportunity lies ahead to dissect complex, quantitative traits when both genotype and phenotype can be assessed at a high level of detail. This is especially true for the study of natural variation in photosynthetic efficiency, for which forward genetics studies have yielded only a little progress in our understanding of the genetic layout of the trait. High‐throughput phenotyping, primarily from chlorophyll fluorescence imaging, should help to dissect the genetics of photosynthesis at the different levels of both plant physiology and development. Specific emphasis should be directed towards understanding the acclimation of the photosynthetic machinery in fluctuating environments, which may be crucial for the identification of genetic variation for relevant traits in food crops. Facilities should preferably be designed to accommodate phenotyping of photosynthesis‐related traits in such environments. The use of forward genetics to study the genetic architecture of photosynthesis is likely to lead to the discovery of novel traits and/or genes that may be targeted in breeding or bio‐engineering approaches to improve crop photosynthetic efficiency. In the near future, big data approaches will play a pivotal role in data processing and streamlining the phenotype‐to‐gene identification pipeline.
Surfing the Waves of the CMJ; Are There between-Sport Differences in the Waveform Data?

The ability to analyse countermovement jump (CMJ) waveform data using statistical methods, like principal component analysis, can provide additional information regarding the different phases of the CMJ, compared to jump height or peak power alone. The aim of this study was to investigate the between-sport force-time curve differences in the CMJ. Eighteen high level golfers (male = 10, female = 8) and eighteen high level surfers (male = 10, female = 8) performed three separate countermovement jumps on a force platform. Time series of data from the force platform was normalized to body weight and each repetition was then normalized to 0–100 percent. Principal component analyses (PCA) were performed on force waveforms and the first six PCs explained 35% of the variance in force parameters. The main features of the movement cycles were characterized by magnitude (PC1 and PC5), waveform (PC2 and PC4), and phase shift features (PC3). Surf athletes differ in their CMJ technique and show a greater negative centre of mass displacement when compared to golfers (PC1), although these differences are not necessarily associated with greater jump height. Principal component 5 demonstrated the largest correlation with jump height (R2 = 0.52). Further studies are recommended in this area, to reveal which features of the CMJ that relate to jumping performance, and sport specific adaptations.
Chemical Profiles and Anti-inflammatory Activity of the Essential Oils from Seseli gummiferum and Seseli corymbosum subsp. corymbosum

The anti-inflammatory activity of the essential oils from Seseli corymbosum subsp. corymbosum Pall. ex Sm. (SC) and Seseli gummiferum Boiss. & Heldr. subsp. corymbosum (SG) was investigated for the first time on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. The main constituents (determined by GC-FID and GC-MS analyses) were germacrene D (54.1%) and sabinene (22.4%) in SG oil and β-phellandrene (29.2%), α-phellandrene (8.2%) and germacrene D (2.5%) in SC oil. SC and SG oils inhibited nitric oxide (NO) production with IC50 values of 56.1 and 108.2 μg/mL, respectively. The oils also inhibited prostaglandin E2 (PGE2) with IC50 values of 49.4 μg/mL (SC oil) and 95.5 μg/mL (SG oil). The inhibitory effect of SC and SG oils was accompanied by dose-dependent decreases of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) protein expressions in LPS-induced RAW 264.7 cells. The research of the reporter gene assay on nuclear factor κB (NF-κB) showed that SC and SG oils inhibited NF-κB transcriptional activity. The obtained results suggest that SC and SG oils exert the anti-inflammatory effects in LPS-stimulated RAW 264.7 cells by suppressing NF-κB activation.
“What matters to you?” A longitudinal qualitative study of Norwegian patients’ perspectives on their pathways with colorectal cancer

ABSTRACT Purpose: Person-centred care (PCC) is a well-acknowledged goal throughout the western world both within the health care services sector and for the patients themselves. To be able to create a future health care system that includes improved PCC, we need more in-depth knowledge of what matters to patients, how “what matters” might change over time, and tentative descriptions of commonalities across patients’ perspectives. The aim of this study is to contribute to this knowledge base. Methods: We conducted a qualitative interview series over one year with nine Norwegian patients who were recently diagnosed with rectal cancer tumor-node-metastasis stage I–III. Results: We found that: (1) patients have an initial focus on “biological goals” and conventional treatment; (2) pathways are unique and dynamic; (3) family and friends affected patient pathways positively with respect to meaningfulness and quality of life, but for some participants also negatively because there were heavy burdens of caretaking; (4) receiving help in the health care system depended on the patients’ navigation skills; (5) pluralism in health-seeking behaviour was important in all patient pathways. Conclusion: Long lasting illness may be a dynamic and complex journey. These results represent some features of a pathway with cancer and are important because they contribute with knowledge about what matters most seen from the cancer patients’ point of view.
Tuberculosis Transmission in Households and Classrooms of Adolescent Cases Compared to the Community in China

The aim of this paper is to evaluate the link between the history of exposure to tuberculosis (TB) in the household and diagnosed TB cases at school, and to compare the detection rate of active TB among household contacts and classroom contacts of adolescent TB cases with the rates among contacts of healthy controls. From November 2016 to December 2017, a prospective matched case-control study was conducted using passively identified index adolescent student cases from the TB surveillance system and healthy controls (matched by county, school type, sex, age and ethnicity). Contacts in households and classrooms of index cases and of controls were investigated. Matched tabulation of 117 case-control pairs revealed exposure to TB in the household as a strong risk factor (odds ratio (OR) = 21.0, 95% confidence interval (CI): 3.4, 868.6). Forty-five (case detection rate 0.69%) and two (case detection rate 0.03%) new active TB cases were detected among 6512 and 6480 classroom contacts of the index cases and controls, respectively. Having an index case in the classroom significantly increased the risk of classmates contracting active TB (OR = 22.5, 95% CI: 5.9, 191.4). Our findings suggested that previous exposure to TB in the household could lead a child to catch TB at school, then spread TB to classmates.
Early term effects of rhBMP-2 on pedicle screw fixation in a sheep model: histomorphometric and biomechanical analyses.

Background The effects of recombinant human bone morphogenetic protein-2 (rhBMP-2) on pedicle screw pullout force and its potential to improve spinal fixation have not previously been investigated. rhBMP-2 on an absorbable collagen sponge (ACS) carrier was delivered in and around cannulated and fenestrated pedicle screws in a sheep lumbar spine instability model. Two control groups (empty screw and ACS with buffer) were also evaluated. We hypothesized that rhBMP-2 could stimulate bone growth in and around the cannulated and fenestrated pedicle screws to improve early bone purchase. Methods Eight skeletally mature sheep underwent destabilizing laminectomies at L2-L3 and L4-L5 followed by stabilization with pedicle screw and rod constructs. An ACS carrier was used to deliver 0.15 mg of rhBMP-2 within and around the cannulated and fenestrated titanium pedicle screws. Biomechanics and histomorphometry were used to evaluate the early term results at 6 and 12 postoperative weeks. Results rhBMP-2 was unable to improve bony purchase of the cannulated and fenestrated pedicle screws compared to both control groups. Although rhBMP-2 groups had pullout forces that were less than both control groups, both rhBMP-2 groups had pullout force values exceeding 2,000 N, which was comparable to previously published results for unmodified pedicle screws. Significant differences in the percentages of bone in peri-screw tissues was not observed amongst the four treatment groups. Microradiography and quantitative histomorphometry showed that at 6 weeks, rhBMP-2 induced peri-screw remodeling regions containing peri-implant bone which was hypodense with respect to surrounding native trabeculae. A moderate correlation between biomechanical pullout variables and histomorphometry data was observed. Conclusions The design of the cannulated and fenestrated pedicle screw was able to facilitate new bone formation to achieve high pullout forces. However, delivery of rhBMP-2 should be carefully controlled to prevent excessive bone remodeling which could cause early screw loosening.
A phase II study of a modified hyper-CVAD frontline therapy for patients with adverse risk diffuse large B-cell and peripheral T-cell non-Hodgkin lymphoma

Abstract To improve complete remission (CR) rates by reducing toxicity and enhancing delivery, we created a modified hyper-CVAD/MA regimen (cyclophosphamide, vincristine, doxorubicin, dexamethasone/methotrexate, cytarabine) by reducing the cytarabine dose (3 g/m2 to 2 g/m2) and number of cycles (eight to six). We conducted a phase II trial in the pre-rituximab era in the intermediate–high international prognostic index (IPI) (≥2) de novo diffuse large B-cell lymphoma (DLBCL) and peripheral T-cell lymphoma (PTCL) (ACTRN12605000105640). CR rates were compared with reported IPI-stratified rates. Sixty-three patients (n = 26 PTCL; n = 37 DLBCL) were evaluated; median follow-up of 30 months. CR rates for PTCL and DLBCL patients were 46% and 49%, respectively, similar with reported CR rates with CHOP-like chemotherapy (p = .6). Of the patients, 51 (81%) experienced ≥1 unplanned hospital admission; only 41 (65%) completed six cycles. The cytarabine modifications did not prevent significant toxicity. Modified hyper-CVAD/MA resulted in similar outcomes to CHOP-like chemotherapy in aggressive lymphomas and was associated with significant toxicity. Trial registration: Australian New Zealand Clinical Trials Registry identifier: ACTRN12605000105640.
Comparative Analysis of Load Profile between Small-Sided Games and Official Matches in Youth Soccer Players

The purposes of the present study are: (a) to characterize the external (eTL) and internal load (iTL) of official matches and small-sided games (SSGs) in relation to their objective, (b) to compare demands between SSG, and (c) to analyze the SSG requirements in relation to official matches during a one-month competition period. Twenty under-18 national-level soccer players were recorded using WIMUTM inertial devices (RealTrack Systems, Almeria, Spain) during four official matches and 12 training sessions where four SSGs with different objectives were performed: (SSG1) keeping the ball; (SSG2) keeping the ball and progressing; (SSG3) keeping the ball, progressing and ending in mini-goals; and (SSG4) keeping the ball, progressing and ending in an official goal with a goalkeeper. Statistical analysis included Kruskall-Wallis’ H and Mann-Whitney’s U with Cohen’s d effect size. The SSGs presented walking and jogging intensity movements (0.7–7 to 7–14 km/h), with a 5-to-8 %HIA (high intensity activity, >16 km/h), where low intensity accelerations, decelerations and impacts were predominant (1–2.5 m/s2; 5–7 G), and %HRMAX (maximum heart rate percentage) was between 70–90%. Only SSG4 presented similar demands to competition, finding differences between SSGs (p < 0.05; d = 1.40 − 0.36). In conclusion, the objective of the SSGs directly influenced the demands on the players in training sessions. For this reason, it is important to monitor demands for designing specific training sessions.
RVFV Infection in Goats by Different Routes of Inoculation

Rift Valley fever virus (RVFV) is a zoonotic arbovirus of the Phenuiviridae family. Infection causes abortions in pregnant animals, high mortality in neonate animals, and mild to severe symptoms in both people and animals. There is currently an ongoing effort to produce safe and efficacious veterinary vaccines against RVFV in livestock to protect against both primary infection in animals and zoonotic infections in people. To test the efficacy of these vaccines, it is essential to have a reliable challenge model in relevant target species, including ruminants. We evaluated two goat breeds (Nubian and LaMancha), three routes of inoculation (intranasal, mosquito-primed subcutaneous, and subcutaneous) using an infectious dose of 107 pfu/mL, a virus strain from the 2006–2007 Kenyan/Sudan outbreak and compared the effect of using virus stocks produced in either mammalian or mosquito cells. Our results demonstrated that the highest and longest viremia titers were achieved in Nubian goats. The Nubian breed was also efficient at producing clinical signs, consistent viremia (peak viremia: 1.2 × 103–1.0 × 105 pfu/mL serum), nasal and oral shedding of viral RNA (1.5 × 101–8 × 106 genome copies/swab), a systemic infection of tissues, and robust antibody responses regardless of the inoculation route. The Nubian goat breed and a needle-free intranasal inoculation technique could both be utilized in future vaccine and challenge studies. These studies are important for preventing the spread and outbreak of zoonotic viruses like RVFV and are supported by the Canadian-led BSL4ZNet network.
