Viral infections can lead to interferon production, which achieves its antiviral function primarily by activating the JAK/STAT pathway and inducing multiple interferon-stimulated genes (ISGs). Although considerable ISGs have been identified in antiviral researches, little is known about ISGs in bluetongue virus (BTV) infection. Viperin is the most highly induced ISG following BTV infection, which suggests that it may play a critical role in the anti-BTV immune response. The aim of this study was to characterize ovine Viperin (oViperin) and explore whether it can inhibit BTV replication. We cloned the coding sequences (CDS) of sheep Viperin, and the sequence analysis showed that oViperin displayed a high similarity with other species. oViperin has a leucine zipper in the N-terminal, a CxxxCxxC motif in the SAM domain, and a conservative C-terminus. We found that oViperin mRNA expression was significantly up-regulated in a time- and multiplicity of infection (MOI)-dependent manner following BTV infection. oViperin overexpression resulted in a significant inhibition in BTV replication, whereas an oViperin knockdown in MDOK cells increased BTV replication. This study shows for the first time, that oViperin has antiviral activity towards BTV infection and provides important information to research the interaction between BTV and oViperin.

Non-nutritive suck (NNS) is one piece of the complex oral feeding process, yet there is paucity on how it develops throughout the first year of life.

To determine changes in infant NNS between 3 and 12months of age.

Twenty-six full-term infants (65% male) completed this study. All infants were offered our custom research pacifier to attain a quantitative analysis of their suck pattern. Based on quantitative analyses of NNS cycle count, the best 2min of infants' suck were selected and analyzed.

NNS duration, amplitude, cycles/burst, frequency, cycles, and bursts.

NNS duration, bursts, cycles/burst and cycles significantly decreased from 3 to 12months, yet amplitude significantly increased over the same time period. Additionally, no significant differences were evident for NNS frequency. Three-month-old infants produced a median of 4.50 suck bursts per minute that contained 9.60cycles/burst, resulting in a burst duration of 4.74s. The median NNS frequency was 2.09Hz, with an average amplitude of 14.05 cmH

0. Twelve-month-old infants produced a median of 2.50 suck bursts that contained 3.75cycles/burst, resulting in a burst duration of 1.67s. The median NNS frequency was 2.11Hz with an amplitude of 19.75 cmH

0.

Full-term infants significantly change their NNS duration, amplitude, burst number, cycles/burst and cycle number with no significant changes present in NNS frequency between 3 and 12months. Knowledge of NNS emergence and maturation during the first year of life is imperative for proper NNS assessment so that healthcare professionals can identify delays.

Incarceration carries several negative ramifications for population health, while diverting scarce resources from other public goods. At a time when health care systems around the world are strained, the current study investigates the long-term relationship between incarceration and health care infrastructure.

We investigated the longitudinal association between incarceration rates and hospital beds per capita for 36 countries between 1971 and 2015.

Fixed effects regression analyses were employed to examine the effect of within-country changes in incarceration rates on hospital beds per capita.

Findings demonstrated that increases in national incarceration rates over time were associated with declines in hospital beds per capita, net of controls for socio-demographic and economic factors.

Increased incarceration negatively impacts hospital bed availability at the cross-national level.

To synthesize evidence on accelerometer-measured moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) levels of Chinese children and adolescents.

This is both a systematic review and meta-analysis study.

Online databases were searched for studies published from January 2009 up to February 2019. These studies reported accelerometer-measured daily minutes of MVPA and/or SB among Chinese children and adolescents. Random-effects meta-analysis was used to separately pool the time spent in MVPA and SB.

Of 4754 records, 20 studies were included in the meta-analysis. Sample sizes ranged from 96 to 2163. The meta-analysis showed that Chinese children and adolescents spent 41.11min/day in MVPA and 529.83min/day in SB averagely. Boys spent more time in MVPA compared with girls (P=0.01). Children accumulated more MVPA time than adolescents (P=0.05), and children spent less time in SB than adolescents (P=0.05). Unlike weekdays, SB was lower on weekends (P=0.02). There were significant differences in children and adolescents' MVPA time in regions (P<0.001).

MVPA level in Chinese children and adolescents is well below international recommendations, and their SB level is very high.

In England, notifications of invasive group A streptococcal (iGAS) infections have increased since 2015. We describe time trends, risk factors, as well as clinical and infection characteristics amongst iGAS cases in North West England, focussing on people who inject drugs (PWIDs), prisoners and homeless populations (referred to as risk groups), and analyse factors for fatal infection.

The study design used was a cross-sectional study.

Data for all iGAS cases notified to Public Health England North West between January 2016 and May 2019 were used. Analysis consisted of time trend analysis, descriptive statistics, hypothesis testing to investigate differences in clinical and infection characteristics between risk and non-risk groups and binary logistic regression to identify factors associated with fatal infection.

There were 1353 cases. Two hundred and two were amongst risk groups, who were predominantly PWIDs in Greater Manchester. Soft tissue risk factors were widespread. There were differences in strain-type between risk and non-risk groups.
