Exercise and physical activity in asylum seekers in Northern England; using the theoretical domains framework to identify barriers and facilitators
Background
Many asylum seekers have complex mental health needs which can be exacerbated by the challenging circumstances in which they live and difficulties accessing health services. Regular moderate physical activity can improve mental health and would be a useful strategy to achieve this. Evidence suggests there are barriers to engaging black and minority ethnic groups in physical activity, but there is little research around asylum seekers to address the key barriers and facilitators in this group.
Methods
A two stage qualitative study used semi-structured interviews underpinned by the Theoretical Domains Framework. The interviews were conducted in voluntary sector groups in four towns/ cities in Northern England. Purposive sampling recruited 36 asylum seekers from 18 different countries. Interviews were audio recorded, transcribed verbatim and subject to framework analysis. Stage two involved a nominal group technique with five key stakeholders including asylum seekers and those that work with them. They followed a four stage process to rank and reach consensus on the key barrier to undertaking physical activity/ exercise that could be addressed locally through a future intervention.
Results
A number of barriers and facilitators were identified including a lack of understanding of the term physical activity and recommended levels but knowledge of the health benefits of physical activity/ exercise and the motivation to increase levels having engaged with activities back home. Living as an asylum seeker was considered a barrier due to the stress, poverty and temporary nature of living in an unfamiliar place. The outcome of the nominal group technique was that a lack of knowledge of facilities in the local area was the prevailing barrier that could be addressed.
Conclusions
Public health practitioners could develop interventions which capitalise on the motivation and knowledge of asylum seekers to encourage an increase in physical activity which may in turn reduce the breadth and depth of mental health needs of this group
The HELLAS2XMM Survey. XII. The infrared/sub-millimeter view of an X-ray selected Type 2 quasar at z=2
We present multi-wavelength observations (from optical to sub-millimeter,
including Spitzer and SCUBA) of H2XMMJ 003357.2-120038 (also GD158_19), an
X-ray selected, luminous narrow-line (Type 2) quasar at z=1.957 selected from
the HELLAS2XMM survey. Its broad-band properties can be reasonably well modeled
assuming three components: a stellar component to account for the optical and
near-IR emission, an AGN component (i.e., dust heated by an accreting active
nucleus), dominant in the mid-IR, with an optical depth at 9.7 micron along the
line of sight (close to the equatorial plane of the obscuring matter) of
tau(9.7)=1 and a full covering angle of the reprocessing matter (torus) of 140
degrees, and a far-IR starburst component (i.e., dust heated by star formation)
to reproduce the wide bump observed longward of 70 micron. The derived
star-formation rate is about 1500 solar masses per year. The overall modeling
indicates that GD158_19 is a high-redshift X-ray luminous, obscured quasar with
coeval powerful AGN activity and intense star formation. It is probably caught
before the process of expelling the obscuring gas has started, thus quenching
the star formation.Comment: 7 pages, 3 figures, 1 table, accepted for publication by MNRA
Catalog of Radio Galaxies with z>0.3. I:Construction of the Sample
The procedure of the construction of a sample of distant () radio
galaxies using NED, SDSS, and CATS databases for further application in
statistical tests is described. The sample is assumed to be cleaned from
objects with quasar properties. Primary statistical analysis of the list is
performed and the regression dependence of the spectral index on redshift is
found.Comment: 9 pages, 6 figures, 2 table
Review: A critical evaluation of arguments opposing male circumcision for HIV prevention in developed countries
A potential impediment to evidence-based policy development on medical male circumcision (MC) for HIV prevention in all countries worldwide is the uncritical acceptance by some of arguments used by opponents of this procedure. Here we evaluate recent opinion-pieces of 13 individuals opposed to MC. We find that these statements misrepresent good studies, selectively cite references, some containing fallacious information, and draw erroneous conclusions. In marked contrast, the scientific evidence shows MC to be a simple, low-risk procedure with very little or no adverse long-term effect on sexual function, sensitivity, sensation during arousal or overall satisfaction. Unscientific arguments have been recently used to drive ballot measures aimed at banning MC of minors in the USA, eliminate insurance coverage for medical MC for low-income families, and threaten large fines and incarceration for health care providers. Medical MC is a preventative health measure akin to immunisation, given its protective effect against HIV infection, genital cancers and various other conditions. Protection afforded by neonatal MC against a diversity of common medical conditions starts in infancy with urinary tract infections and extends throughout life. Besides protection in adulthood against acquiring HIV, MC also reduces morbidity and mortality from multiple other sexually transmitted infections (STIs) and genital cancers in men and their female sexual partners. It is estimated that over their lifetime one-third of uncircumcised males will suffer at least one foreskin-related medical condition. The scientific evidence indicates that medical MC is safe and effective. Its favourable risk/benefit ratio and cost/benefit support the advantages of medical MC
A deep Chandra observation of the Groth Strip. I. The X-ray data
We present the results of a 200 ks Chandra observation of part of the Groth
Strip region, using the ACIS-I instrument. We present a relatively simple
method for the detection of point-sources and calculation of limiting
sensitivities, which we argue is at least as sensitive and more self-consistent
than previous methods presented in the literature. 158 distinct X-ray sources
are included in our point-source catalogue in the ACIS-I area. The number
counts show a relative dearth of X-ray sources in this region. For example at a
flux limit of 1E-15 (cgs) around 20 per cent more soft band sources are
detected in the HDF-N and almost 50 per cent more in the ELAIS-N1 field, which
we have analysed by the same method for comparison. We find, however, that
these differences are consistent with Poisson variations at 2 sigma
significance, and therefore there is no evidence for cosmic variance based on
these number counts alone. We determine the average spectra of the objects and
find a marked difference between the soft-band selected sources, which have
Gamma=1.9 typical of unobscured AGN, and the hard-band selected sources, which
have Gamma=1.0. Reassuringly, the sample as a whole has a mean spectrum of
Gamma=1.4\pm 0.1, the same as the X-ray background. Nonetheless, our results
imply that the fraction of sources with significant obscuration is only ~25 per
cent, much less than predicted by standard AGN population synthesis models.
This is confirmed by direct spectral fitting, with only a handful of objects
showing evidence for absorption. After accounting for absorption, all objects
are consistent with mean intrinsic spectrum of Gamma=1.76 \pm 0.08, very
similar to local Seyferts (abridged).Comment: 17 pages, 4 figures, MNRAS, in pres
Activity in galactic nuclei of cluster and field galaxies in the local universe
We study the environmental effects on the activity in galactic nuclei by
comparing galaxies in clusters and in the field. Using a spectroscopic sample
of galaxies in Abell clusters from the SDSS DR7, we investigate the dependence
of nuclear activity on the physical parameters of clusters as well as the
nearest neighbor galaxy. We also compare galaxy properties between AGN hosts
and non-AGN galaxies. We find that the AGN fraction of early-type galaxies
starts to decrease around one virial radius of clusters (r_{200,cl}) as
decreasing clustercentric radius, while that of late types starts to decrease
close to the cluster center (R~0.1-0.5r_{200,cl}). The AGN fractions of
early-type cluster galaxies on average are found to be lower than those of
early-type field galaxies by a factor ~3. However, the mean AGN fractions of
late-type cluster galaxies are similar to those of late-type field galaxies.
The AGN fraction of early-type BCGs lies between those of other early-type,
cluster and field galaxies with similar luminosities. In the field, the AGN
fraction strongly depends on the morphology of and the distance to the nearest
neighbor galaxy. We find an anti-correlation between the AGN fraction and the
velocity dispersion of clusters for all subsamples divided by morphology and
luminosity of host galaxies. The AGN power indicated by L_[OIII]/M_BH is found
to depend strongly on the mass of host galaxies rather than the clustercentric
radius. The difference in physical parameters such as luminosity, (u-r) colors,
SFRs, and (g-i) color gradients between AGN hosts and non-AGN galaxies is seen
for both early and late types at all clustercentric radii, while the difference
in structure parameters between the two is significant only for late types.
These results support the idea that the nuclear activity is triggered through
galaxy-galaxy interactions and mergers when gas supply for AGN is available.Comment: 15 pages, 13 figures. To appear in A&
A 'snip' in time: what is the best age to circumcise?
<p>Abstract</p> <p>Background</p> <p>Circumcision is a common procedure, but regional and societal attitudes differ on whether there is a need for a male to be circumcised and, if so, at what age. This is an important issue for many parents, but also pediatricians, other doctors, policy makers, public health authorities, medical bodies, and males themselves.</p> <p>Discussion</p> <p>We show here that infancy is an optimal time for clinical circumcision because an infant's low mobility facilitates the use of local anesthesia, sutures are not required, healing is quick, cosmetic outcome is usually excellent, costs are minimal, and complications are uncommon. The benefits of infant circumcision include prevention of urinary tract infections (a cause of renal scarring), reduction in risk of inflammatory foreskin conditions such as balanoposthitis, foreskin injuries, phimosis and paraphimosis. When the boy later becomes sexually active he has substantial protection against risk of HIV and other viral sexually transmitted infections such as genital herpes and oncogenic human papillomavirus, as well as penile cancer. The risk of cervical cancer in his female partner(s) is also reduced. Circumcision in adolescence or adulthood may evoke a fear of pain, penile damage or reduced sexual pleasure, even though unfounded. Time off work or school will be needed, cost is much greater, as are risks of complications, healing is slower, and stitches or tissue glue must be used.</p> <p>Summary</p> <p>Infant circumcision is safe, simple, convenient and cost-effective. The available evidence strongly supports infancy as the optimal time for circumcision.</p
