Public interest in hyaluronic acid injections for knee osteoarthritis in the United States and Europe: An international Google Trends analysis
BACKGROUND: Hyaluronic acid injections remain a common nonsurgical alternative for the treatment of knee osteoarthritis despite limited clinical evidence and varying global recommendations regarding its use. We used the Google Trends tool to provide a quantitative analysis of public interest in hyaluronic acid injections for knee osteoarthritis in the United States and Europe.
METHODS: We customized Google Trends parameters to obtain search data from January 2009 to December 2019 in both the United States and Europe. Combinations of arthritis , osteoarthritis , hyaluronic acid , knee arthritis , knee osteoarthritis , and knee injection were entered into the Google Trends tool, and trend analyses were performed.
RESULTS: The models generated to describe public interest in hyaluronic acid for knee injections in both the United States and Europe showed increased Google queries as time progressed (
CONCLUSIONS: Our results indicate a significant increase in Google queries related to hyaluronic acid injections for knee osteoarthritis since 2009 in both the United States and Europe. Our models suggest that despite mixed evidence supporting its use, orthopedic surgeons should expect continued public interest in hyaluronic acid for knee osteoarthritis. The results of our study may help to prepare surgeons for patient inquiries, inform the creation of evidence-based shared decision-making tools, and direct future research
Seeking help for tinnitus and satisfaction with healthcare providers including diagnosis, clinical services, and treatment : a scoping review
The objective of this scoping review was to describe the extent and type of evidence related to seeking help for tinnitus and
satisfaction with healthcare providers including diagnosis, services and treatments along the clinical pathway. The selection
criteria were adults aged 18 and over with tinnitus who sought help and where patient satisfaction with healthcare providers was
reported. Online databases MEDLINE (OvidSP), Embase (OvidSP), PsycINFO (OvidSP) and CINAHL plus (EBSCO) were
searched for original studies in English. The search had no date limit. Twenty-one records were eligible for data extraction.
Studies reported that the most common healthcare providers seen were general practitioners, ear, nose and throat specialists
and audiologists. Depression and tinnitus severity were related to an increase in the number of times help was sought and the
type of healthcare provider seen may also impact patient satisfaction. The majority of participants were unlikely to receive a
referral to a specialist at the initial GP consultation. Although there is limited research in this area, help-seekers for tinnitus were
generally dissatisfied and reported negative interactions with healthcare providers. However, once in a specialised tinnitus
clinical setting, studies reported that most help-seekers were satisfied and had positive interactions with healthcare providers.journals.sagepub.com/home/ehpam2024Speech-Language Pathology and AudiologySDG-03:Good heatlh and well-bein
A Strategy for Finding Near Earth Objects with the SDSS Telescope
We present a detailed observational strategy for finding Near Earth Objects
(NEOs) with the Sloan Digital Sky Survey (SDSS) telescope. We investigate
strategies in normal, unbinned mode as well as binning the CCDs 2x2 or 3x3,
which affects the sky coverage rate and the limiting apparent magnitude. We
present results from 1 month, 3 year and 10 year simulations of such surveys.
For each cadence and binning mode, we evaluate the possibility of achieving the
Spaceguard goal of detecting 90% of 1 km NEOs (absolute magnitude H <= 18 for
an albedo of 0.1). We find that an unbinned survey is most effective at
detecting H <= 20 NEOs in our sample. However, a 3x3 binned survey reaches the
Spaceguard Goal after only seven years of operation. As the proposed large
survey telescopes (PanStarss; LSST) are at least 5-10 years from operation, an
SDSS NEO survey could make a significant contribution to the detection and
photometric characterization of the NEO population.Comment: Accepted by AJ -- 12 pages, 11 figure
The impact of tinnitus upon cognition in adults : a systematic review
OBJECTIVE : To systematically review and analyse experimental outcomes of studies exploring the impact of tinnitus upon cognitive function and their implications for clinical management of invasive tinnitus. DESIGN : A systematic and descriptive review. STUDY SAMPLE : Eighteen studies were identified investigating the impact of tinnitus on cognitive function. RESULTS : The 18 studies evaluated cognitive function using 24 different objective behavioural tests, nine electrophysiological recordings, one oculomotor test, and one self-report questionnaire. The studies spanned 18 years and revealed numerous interactions potentially contributing to the cognitive difficulties frequently reported by people with invasive tinnitus. The studies indicate a clear association between tinnitus and aspects of cognitive function, specifically the executive control of attention. CONCLUSIONS : Tinnitus impairs cognitive function by way of impact upon executive control of attention. Clinical management of patients reporting tinnitus and cognitive difficulties requires an understanding of the reciprocal relationship between tinnitus and cognitive function, with additive effects of anxiety, depression, and somatic cognitive bias. Further study is required to establish the impact of advancing age, hearing loss, anxiety, depression tinnitus duration, and distress upon cognitive function in people with invasive tinnitus.The authors would like to acknowledge the support of the Ear Science Institute Australia and the Lions Hearing Clinic.http://www.tandfonline.com/loi/iija202017-05-31hb2017Speech-Language Pathology and Audiolog
Brief of Corporate Law Professors as Amici Curie in Support of Respondents
The Supreme Court has looked to the rights of corporate shareholders in determining the rights of union members and non-members to control political spending, and vice versa. The Court sometimes assumes that if shareholders disapprove of corporate political expression, they can easily sell their shares or exercise control over corporate spending. This assumption is mistaken. Because of how capital is saved and invested, most individual shareholders cannot obtain full information about corporate political activities, even after the fact, nor can they prevent their savings from being used to speak in ways with which they disagree. Individual shareholders have no “opt out” rights or practical ability to avoid subsidizing corporate political expression with which they disagree. Nor do individuals have the practical option to refrain from putting their savings into equity investments, as doing so would impose damaging economic penalties and ignore conventional financial guidance for individual investors
Color Confirmation of Asteroid Families
We discuss optical colors of 10,592 asteroids with known orbits selected from
a sample of 58,000 moving objects observed by the Sloan Digital Sky Survey
(SDSS). This is more than ten times larger sample that includes both orbital
parameters and multi-band photometric measurements than previously available.
We confirm that asteroid dynamical families, defined as clusters in orbital
parameter space, also strongly segregate in color space. In particular, we
demonstrate that the three major asteroid families (Eos, Koronis, and Themis),
together with the Vesta family, represent four main asteroid color types. Their
distinctive optical colors indicate that the variations in chemical composition
within a family are much smaller than the compositional differences between
families, and strongly support earlier suggestions that asteroids belonging to
a particular family have a common origin. We estimate that over 90% of
asteroids belong to families.Comment: 18 pages, color figures, accepted by A
A General Definition of "Conserved Quantities" in General Relativity and Other Theories of Gravity
In general relativity, the notion of mass and other conserved quantities at
spatial infinity can be defined in a natural way via the Hamiltonian framework:
Each conserved quantity is associated with an asymptotic symmetry and the value
of the conserved quantity is defined to be the value of the Hamiltonian which
generates the canonical transformation on phase space corresponding to this
symmetry. However, such an approach cannot be employed to define `conserved
quantities' in a situation where symplectic current can be radiated away (such
as occurs at null infinity in general relativity) because there does not, in
general, exist a Hamiltonian which generates the given asymptotic symmetry.
(This fact is closely related to the fact that the desired `conserved
quantities' are not, in general, conserved!) In this paper we give a
prescription for defining `conserved quantities' by proposing a modification of
the equation that must be satisfied by a Hamiltonian. Our prescription is a
very general one, and is applicable to a very general class of asymptotic
conditions in arbitrary diffeomorphism covariant theories of gravity derivable
from a Lagrangian, although we have not investigated existence and uniqueness
issues in the most general contexts. In the case of general relativity with the
standard asymptotic conditions at null infinity, our prescription agrees with
the one proposed by Dray and Streubel from entirely different considerations.Comment: 39 pages, no figure
Investigating the prevalence and impact of device-related problems associated with hearing aid use
OBJECTIVE : To explore the prevalence of device-related problems associated with hearing aid use, participants’ help-seeking behaviours for these problems, and factors associated with hearing aid problems.
DESIGN : A prospective convenience cohort design surveying 413 adult hearing aid users (34–97 years of age) recruited from seven clinics across Australia.
RESULTS : Almost all participants (98%) indicated that they were experiencing at least one of the hearing aid problems included on the survey. The number of hearing aid related problems reported by participants ranged from 0 to 25 (of a possible 26), with a mean of 10 problems (SD = 5). The three most reported problems were related to difficulty hearing in noisy environments, hearing in windy environments, and understanding certain voices. Participants had reported less than half (46.33%) of the total problems identified to their clinic (range = 0–100%, mean = 43.40, SD = 13.92). Participants who reported experiencing a greater number of hearing aid problems also reported lower levels of hearing aid benefit, and satisfaction with their hearing aids.
CONCLUSIONS : The majority of hearing aid owners experience problems with their hearing aids. Addressing these problems would likely contribute to improved hearing aid outcomes.Portions of this article were presented at the ACAud National Congress 2017, Adelaide, SA, August 2017, at the Audiology Australia Chapter conferences in Perth, Adelaide and Hobart, November 2017, at the HAASA National Conference, Sydney NSW, May 2018, and at the Audiology Australia National Congress, Sydney NSW, May 2018.Australian Postgraduate Award scholarship through The University of Western Australia.http://www.tandfonline.com/loi/iija20hj2021Speech-Language Pathology and Audiolog
