Digital community assets: Investigating the impact of online engagement with arts and peer support groups on mental health during COVID-19
The digitisation of mental health support has acceler- ated since the outbreak of the COVID-19 pandemic. This study investigated the impact of digital engagement with community assets on mental health during COVID- 19. Digital engagement is typically not location-bound, but the restricted movement enforced during ‘lock- downs’ meant that people were primarily accessing digital community assets from their home environ- ments. We report findings from a study utilising two creative workshops and semi-structured interviews to investigate how support operates in and through three digital community assets; an online peer support forum, a social enterprise running regular creative challenges nationally via social media and a local in-person crea- tive arts support group. The concept of ‘more or less digital’ captures the ways that people’s experiences of digital community assets extend beyond the platforms to incorporate settings of use. The analysis identifies how support is diluted through digital engagement, the value of minimal and muted forms of engagement and user-led designs for future hybrid forms of support. The article concludes by emphasising the importance of analysing digital community asset engagement in the settings of use and how such knowledge is vital for plan- ning support in a future under continual pressure to be increasingly digital
Sequence variation in the haemagglutinin-neuraminidase gene of human parainfluenza virus type 3 isolates in the UK
The sequence variation in a 934 base-pair region of the gene encoding the haemagglutinin-neuraminidase of five human parainfluenza virus type 3 (HPIV3) isolates was determined together with that of a prototype UK strain. All of the clinical isolates were from the Manchester area of the UK and were obtained in 1990. 1991 and 1993. The gene segment was amplified by the polymerase chain reaction using HPIVB-specific oligonucleotide primers. The nucleotide homology of the strains was high, around 99% and specific differences in the UK sequences when compared with that of the US prototype strain were identified. In addition, a number of isolate-specific differences were seen. No correlation was detected between the observed nucleotide mutations and the year of isolation, which supports the hypothesis that HPIV3 shows cocirculation of a heterogeneous population of viruses rather than varying with time in a linear fashion. However, the data suggested that geographically-defined genetic lineages of HPIV3 may exist
Seasonal Movements, Migratory Behavior, and Site Fidelity of West Indian Manatees along the Atlantic Coast of the United States as Determined by Radio-telemetry
The study area encompassed the eastern coasts of Florida, Georgia, and South Carolina,
including inland waterways such as the St. Johns River (Fig. 1). Manatees inhabited the
relatively narrow band of water that lies between the barrier beaches and the mainland,
occasionally venturing into the ocean close to shore. Between Miami and Fernandina Beach,
Florida, 19 inlets provided manatees with corridors between the intracoastal waters and the
Atlantic Ocean; the distance between adjacent inlets averaged 32 km(SD = 24 km) and varied
from 3 to 88 km. Habitats used by manatees along this 900-km stretch ofcoastline varied
widely and included estuaries, lagoons, rivers and creeks, shallow bays and sounds, and ocean
inlets. Salinities in most areas were brackish, but ranged from completely fresh to completely
marine. The predominant communities of aquatic vegetation also varied geographically and
with salinity: seagrass meadows and mangrove swamps in brackish and marine waters along the
southern half of peninsular Florida; salt marshes in northeastern Florida and Georgia; benthic
macroalgae in estuarine and marine habitats; and a variety of submerged, floating, and emergent
vegetation in freshwater rivers, canals, and streams throughout the region.
Radio-telemetry has been used successfully to track manatees in other regions ofFlorida
(Bengtson 1981, Powell and Rathbun 1984, Lefebvre and Frohlich 1986, Rathbun et al. 1990)
and Georgia (Zoodsma 1991), but these early studies relied primarily on conventional VHF (very
high frequency) transmitters and were limited in their spatial and temporal scope (see O'Shea
and Kochman 1990 for overview). Typically, manatees were tagged at a thermal refuge in the
winter and then tracked until the tag detached, usually sometime between the spring and fall of
the same year. Our study differs from previous research on manatee movements in several
important respects. First, we relied heavily on data from satellite-monitored transmitters using
the Argos system, which yielded a substantially greater number of locations and more systematic
collection of data compared to previous VHF tracking studies (Deutsch et al. 1998). Second, our
tagging and tracking efforts encompassed the entire range of manatees along the Atlantic coast,
from the Florida Keys to South Carolina, so inferences were not limited to a small geographic
area. Third, we often used freshwater to lure manatees to capture sites, which allowed tagging
in all months of the year; this provided more information about summer movement patterns than
had previous studies which emphasized capture and tracking at winter aggregations. Finally, the
study spanned a decade, and success in retagging animals and in replacing transmitters allowed
long-term tracking ofmany individuals. This provided the opportunity to investigate variation in
seasonal movements, migratory behavior, and site fidelity across years for individual manatees.

Prevalence and measurement of anxiety in samples of patients with heart failure
© 2016 Wolters Kluwer Health, Inc. Objectives: Rates of anxiety in patients with heart failure (HF) vary widely, and not all assessment instruments used in this patient population are appropriate. It is timely to consolidate the evidence base and establish the prevalence and variance of anxiety in HF samples. Methods: A systematic review, meta-analysis, and meta-regression were conducted to identify the prevalence, variance, and measurement of anxiety in patients with HF. Results: A total of 14,367 citations were identified, with 73 studies meeting inclusion criteria. A random effects pooled prevalence of 13.1% (95% confidence interval [CI], 9.25%-16.86%) for anxiety disorders, 28.79% (95% CI, 23.30%-34.29) for probable clinically significant anxiety, and 55.5% (95% CI, 48.08%-62.83%) for elevated symptoms of anxiety was identified. Rates of anxiety were highest when measured using the Brief Symptom Scale-Anxiety scale (72.3%) and lowest when measured using the Generalised Anxiety Disorder-7 (6.3%). Conclusion: Many patients with HF would benefit if screened for anxiety and treated. The conceptualization and measurement of anxiety accounted for most variance in prevalence rates. The Generalised Anxiety Disorder-7 or the Hospital Anxiety and Depression Scale appear to be the most appropriate instruments for this clinical population, with evidence to suggest they can discriminate between depression and anxiety, omit somatic items that may contaminate identification of anxiety in a population with physical comorbidities, and provide thresholds with which to differentiate patients and target treatments. Although there are limitations with the collation of diverse measurement methods, the current review provides researchers and clinicians with a more granular knowledge of prevalence estimates of anxiety in a population of HF patients.The research was funded through an interdisciplinary doctoral studentship jointly funded by the Medical Research Council and the Economics and Social Research Council
Sibling risks in cancer: clues to recessive or X-linked genes?
A systematic analysis of cancer risks to offspring and to siblings of cancer cases was carried out based on the nation-wide Swedish Family-Cancer Database. For all 13 cancer sites examined, risks to both offspring and siblings of cases of cancer at the same site were significantly elevated. The relative risk to siblings was approximately 2 fold more than the offspring risk for cancers of the prostate, testis, kidney and bladder, suggesting that recessive or X-linked susceptibility genes may be important for these cancers. Risks to siblings of cases where a parent was also affected were increased >20 fold over population rates for colorectal, ovarian, prostate and renal cancer, and for leukaemia, consistent with the effects of rare high-risk susceptibility alleles. © 2001 Cancer Research Campaign http://www.bjcancer.co
