A systematic review of the literature on the effectiveness of exercise therapy for groin pain in athletes

<p>Abstract</p> <p>Background</p> <p>Athletes competing in sports that require running, changes in direction, repetitive kicking and physical contact are at a relatively higher risk of experiencing episodes of athletic groin pain. To date, there has been no systematic review that aims to inform clinicians about the best available evidence on features of exercise interventions for groin pain in athletes. The primary aim of this systematic review was to evaluate the available evidence on the effectiveness of exercise therapy for groin pain in athletes. The secondary aim of this review was to identify the key features of exercise interventions used in the management of groin pain in an athletic population.</p> <p>Methods</p> <p>MEDLINE, CINAHL, PubMed, SPORTSDiscus, Embase, AMED, Ovid, PEDro, Cochrane Controlled Trials Register and Google Scholar databases were electronically searched. Data relating to research design, sample population, type of sport and exercise intervention was extracted. The methodological evaluation of included studies was conducted by using a modified quantitative critical appraisal tool.</p> <p>Results</p> <p>The search strategy identified 468 studies, 12 of which were potentially relevant. Ultimately five studies were included in this review. Overall the quality of primary research literature was moderate, with only one randomised controlled trial identified. All included studies provided evidence that an exercise intervention may lead to favourable outcomes in terms of return to sport. Four of the five studies reviewed included a strengthening component and most utilised functional, standing positions similar to those required by their sport. No study appropriately reported the intensity of their exercise interventions. Duration of intervention ranged from 3.8 weeks to 16 weeks. All five studies reported the use of one or more co-intervention.</p> <p>Conclusion</p> <p>Best available evidence to date, with its limitations, continues to support common clinical practice of exercise therapy as a key component of rehabilitation for groin pain in athletes. Overall, the available evidence suggests that exercise, particularly strengthening exercise of the hip and abdominal musculature could be an effective intervention for athletes with groin pain. Literature provides foundational evidence that this may need to be in the form of progressive exercises (static to functional) and performed through range. There is currently no clear evidence regarding the most effective intensity and frequency of exercise, because of a lack of reporting in the primary literature.</p

Evolutionary diversification of new caledonian Araucaria

New Caledonia is a global biodiversity hotspot. Hypotheses for its biotic richness suggest either that the island is a ‘museum’ for an old Gondwana biota or alternatively it has developed following relatively recent long distance dispersal and in situ radiation. The conifer genus Araucaria (Araucariaceae) comprises 19 species globally with 13 endemic to this island. With a typically Gondwanan distribution, Araucaria is particularly well suited to testing alternative biogeographic hypotheses concerning the origins of New Caledonian biota. We derived phylogenetic estimates using 11 plastid and rDNA ITS2 sequence data for a complete sampling of Araucaria (including multiple accessions of each of the 13 New Caledonian Araucaria species). In addition, we developed a dataset comprising 4 plastid regions for a wider taxon sample to facilitate fossil based molecular dating. Following statistical analyses to identify a credible and internally consistent set of fossil constraints, divergence times estimated using a Bayesian relaxed clock approach were contrasted with geological scenarios to explore the biogeographic history of Araucaria. The phylogenetic data resolve relationships within Araucariaceae and among the main lineages in Araucaria, but provide limited resolution within the monophyletic New Caledonian species group. Divergence time estimates suggest a Late Cretaceous-Cenozoic radiation of extant Araucaria and a Neogene radiation of the New Caledonian lineage. A molecular timescale for the evolution of Araucariaceae supports a relatively recent radiation, and suggests that earlier (pre-Cenozoic) fossil types assigned to Araucaria may have affinities elsewhere in Araucariaceae. While additional data will be required to adequately resolve relationships among the New Caledonian species, their recent origin is consistent with overwater dispersal following Eocene emersion of New Caledonia but is too old to support a single dispersal from Australia to Norfolk Island for the radiation of the Pacific Araucaria sect.

Efficacy of Triamcinolone Acetonide Extended-Release in Participants with Unilateral Knee Osteoarthritis: A Post Hoc Analysis

Introduction: Osteoarthritis (OA) is common and its prevalence is increased in military service members. In a Phase 3 randomized, controlled trial (NCT02357459), a single intra-articular injection of an extended-release formulation of triamcinolone acetonide (TA-ER) in participants with unilateral or bilateral knee OA demonstrated substantial improvement in pain and symptoms. Bilateral knee pain has emerged as a confounding factor in clinical trials when evaluating the effect of a single intra-articular injection. Furthermore, unilateral disease is frequently first to emerge in active military personnel secondary to prior traumatic joint injury. In this post hoc analysis, we assessed efficacy and safety of TA-ER in a subgroup of participants with unilateral knee OA. Methods: Participants ≥40 years with symptomatic knee OA were randomized to a single intra-articular injection of TA-ER 32 mg, TA crystalline suspension (TAcs) 40 mg, or Saline-placebo. Average daily pain (ADP)‐intensity and rescue medication use were collected at each of Weeks 1-24 postinjection; Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-A (pain), -B (stiffness), -C (function), and Knee Injury and Osteoarthritis Outcome Score Quality of Life (KOOS-QoL) were collected at Weeks 4, 8, 12, 16, 20, 24 postinjection. Adverse events (AEs) were assessed throughout the study. Participants with unilateral knee OA were selected for this analysis. Results: Of 170 participants with unilateral OA (TA-ER, N = 51; Saline-placebo, N = 60; TAcs, N = 59), 42% were male and 89% were white. TA-ER significantly (p < 0.05) improved ADP-intensity vs. Saline-placebo (Weeks 1-24) and TAcs (Weeks 4-21). TA-ER significantly (p < 0.05) improved WOMAC-A vs. Saline-placebo (all time points) and TAcs (Weeks 4, 8, 12, 24). Consistent outcomes were observed for rescue medication, WOMAC-B and -C, and KOOS QoL. AEs were similar in frequency/type across treatments. Conclusion: TA-ER provided 5-6 months’ pain relief that consistently exceeded Saline-placebo and TAcs, suggesting that TA-ER injected intra-articularly into the affected knee may be an effective nonopioid treatment option. Although the participants included in this analysis did not fully represent the diverse demographics of active service members, the substantial unmet medical need in the military population suggests that TA-ER may be an important treatment option; additional studies of TA ER in active military patients are needed
