Is it time to develop specific return to running criteria for ACL rehabilitation? An international survey of physiotherapists criteria for return to running following ACL injury.

OBJECTIVE: To determine return to running criteria currently used by physiotherapists following anterior cruciate ligament (ACL) injury. DESIGN: Self-reported online international survey. METHODS: An online survey of physiotherapists across Australia, the Netherlands and France. RESULTS: A total of 476 respondants participated in the survey across Australia (n = 153), the Netherlands (n = 162), and France (n = 161). For return to running criteria following a non-operative approach, the majority of respondents chose swelling (40.55%, n = 193/476), pain (38.24%, n = 182/476), knee extensor strength (34.34%, n = 163/476), single leg squat (31.93%, n = 152/476) and knee flexor strength (29.83%, n = 142/476). After ACL reconstruction, the highest responses were also swelling (41.18%, n = 196/476), pain (37.18%, n = 177/476), knee extensor strength (37.18%, n = 177/476) and single leg squat (33.19%, n = 158/476). From the identified themes the most common cutoff variables were pain between 0 and 3/10, swelling < grade 1+ and limb symmetry on strength and hop tests >70 %. CONCLUSION: Physiotherapists in Australia, France, and the Netherlands use many different return to running criteria and most of them use more than one criterion. Despite this, there was little consensus on the cut-off physiotherapists use to apply these criteria.

Evolution and environment of Caribbean coastal ecosystems.

Isolation of the Caribbean Sea from the tropical Eastern Pacific by uplift of the Isthmus of Panama in the late Pliocene was associated with major, taxonomically variable, shifts in Caribbean biotic composition, and extinction, but inferred causes of these biological changes have remained elusive. We addressed this through falsifiable hypotheses about how independently determined historical changes in oceanographic conditions may have been responsible. The most striking environmental change was a sharp decline in upwelling intensity as measured from decreases in intra-annual fluctuations in temperature and consequently in planktonic productivity. We then hypothesized three general categories of biological response based upon observed differences in natural history between the oceans today. These include changes in feeding ecology, life histories, and habitats. As expected, suspension feeders and predators became rarer as upwelling declined. However, predicted increases in benthic productivity by reef corals, and benthic algae were drawn out over more than 1 Myr as seagrass and coral reef habitats proliferated; a shift that was itself driven by declining upwelling. Similar time lags occurred for predicted shifts in reproductive life history characteristics of bivalves, gastropods, and bryozoans. Examination of the spatial variability of biotic change helps to understand the time lags. Many older species characteristic of times before environmental conditions had changed tended to hang on in progressively smaller proportions of locations until they became extinct as expected from metapopulation theory and the concept of extinction debt. Faunal turnover may not occur until a million or more years after the environmental changes ultimately responsible.

Patient Decision-Making About Self-Disclosure of a Type 2 Diabetes Diagnosis: A Qualitative Study.

Background: Effective self-management of type 2 diabetes requires receiving support, which can result from disclosing the diagnosis to a support network, including coworkers, family, and friends. As a primarily invisible disease, diabetes allows people to choose whether to disclose. This study qualitatively explores the factors that influence a person's decision to disclose diabetes to others. Methods: Research coordinators recruited 22 interview participants, ranging in age from 32 to 64 years, whose medical records included a diagnosis code for type 2 diabetes. Participants received care from one of two U.S. medical centers. Semi-structured interviews lasted approximately 1 hour and were audio-recorded and professionally transcribed. Verification strategies such as memo-keeping and maintaining methodological coherence/congruence were used throughout analysis to promote rigor. Results: In patients' descriptions of their decision-making processes regarding whether to disclose their diagnosis, six themes emerged. Three motivations prompted open disclosure: 1) to seek information, 2) to seek social support, and 3) to end the succession of diabetes, and the other three motivations prompted guarded disclosure: 4) to prepare for an emergency, 5) to maintain an image of health, and 6) to protect employment. Conclusion: Based on our findings, we recommend three communicative actions for clinicians as they talk to patients about a diabetes diagnosis. First, clinicians should talk about the benefits of disclosure. Second, they should directly address stereotypes in an effort to de-stigmatize diabetes. Finally, clinicians can teach the skills of disclosure. As disclosure efficacy increases, a person's likelihood to disclose also increases. Individuals can use communication as a tool to gain the knowledge and support they need for diabetes self-management and to interrupt the continuing multigenerational development of diabetes within their family.

Patient outcomes of a clinician curriculum on how to deliver a diabetes diagnosis.

AIMS: To investigate the effects of a curriculum that teaches medical decision making and interpersonal communication in the context of prediabetes (preDM) and type 2 diabetes (T2DM). METHODS: This evaluation was an active-controlled trial of 56 patients, including patients who received their diagnosis from intervention-trained clinicians or a control group. Patients attended a research appointment for informed consent and collection of baseline measures. Over the following six months, both groups were mailed surveys and informational handouts monthly. Upon conclusion, we recorded the most recent A1c from the patient's record. RESULTS: An analysis of covariance test revealed patients who received a T2DM diagnosis from an intervention-trained clinician reported higher reassurance from the diagnosing clinician and had a higher perception of threat. Although not statistically significant, patients with T2DM in the intervention group had a lower A1c at follow up and patients in the intervention group reported less poor eating and a higher degree of diet decision making. CONCLUSIONS: The curriculum itself does not influence glycemic control, but our results demonstrate the positive impact on patients of the curriculum to teach critical skills to clinicians delivering a diabetes diagnosis.

Bryozoans, simple invertebrates living on the sea floor, are emerging as a model system for understanding ecological and evolutionary processes on macroevolutionary scales.

Writing Rounds: An Innovation to Increase Physician Scientific Dissemination.

INTRODUCTION: Many high-quality studies presented at conferences never reach the peer-reviewed literature, most likely because physician authors do not take the next step to fully write up the studies and submit them to a journal. We evaluated a curriculum designed to equip authors with the practical skills to submit research projects to peer-reviewed publication. METHODS: We designed a mixed asynchronous-synchronous longitudinal curriculum, occurring across 4 months via a virtual platform. To evaluate the curriculum, we tracked process and production outcomes and conducted semistructured interviews with participants following participation. RESULTS: Across two cohorts in 2019, nine participant authors completed the curriculum. Seven participants submitted their studies for publication; two were accepted. In interviews with eight participants, participant authors described the value of the program, expressing intention to participate again and to recommend it to colleagues. CONCLUSION: Through a coach-directed writing group, participant authors developed the skills and confidence needed to prepare and submit scientific manuscripts for peer review. Curriculum maintenance and enhancement is ongoing. We plan to scale up this innovation in support of other university departments and medical disciplines, developing an implementation guide to describe needed elements, including technological platforms, qualities of the coach, author recruitment, and group conduct.

The transformation of Caribbean coral communities since humans.

The mass die-off of Caribbean corals has transformed many of this region's reefs to macroalgal-dominated habitats since systematic monitoring began in the 1970s. Although attributed to a combination of local and global human stressors, the lack of long-term data on Caribbean reef coral communities has prevented a clear understanding of the causes and consequences of coral declines. We integrated paleoecological, historical, and modern survey data to track the occurrence of major coral species and life-history groups throughout the Caribbean from the prehuman period to the present. The regional loss of Acropora corals beginning by the 1960s from local human disturbances resulted in increases in the occurrence of formerly subdominant stress-tolerant and weedy scleractinian corals and the competitive hydrozoan Millepora beginning in the 1970s and 1980s. These transformations have resulted in the homogenization of coral communities within individual countries. However, increases in stress-tolerant and weedy corals have slowed or reversed since the 1980s and 1990s in tandem with intensified coral bleaching and disease. These patterns reveal the long history of increasingly stressful environmental conditions on Caribbean reefs that began with widespread local human disturbances and have recently culminated in the combined effects of local and global change.

Coral reef-associated bryozoans of Jamaica.

As part of a long-term ecological study of the cryptic comunity of Jamaican coral reefs carried out by Jeremy B.C. Jackson and associates during the 1970s and early 1980s, collections were made of reef bryozoans found at 14 sites around the island. Space occupied by bryozoans on undercoral surfaces is dominated by relatively few species. However, during scanning electrone microscopy study and monograph preparation a diverse assortment of relatively rare species was discovered. Of the 132 species found, 56%, 74 species (70 cheilostomes and 4 cyclostomes) are new, as are one family (Inversiscaphidae) and 5 genera (Planospinella, Caribaria, Spirocoleopora, Gemellitheca, and Palliocella).

Dissonance in the discourse of the duration of diabetes: A mixed methods study of patient perceptions and clinical practice.

BACKGROUND: Remission of diabetes can be rewarding for patients and physicians, but there is limited study of how patients perceive the timeline of a disease along the continuum of glycaemic control. OBJECTIVE: To explore how patients perceive the timeline of diabetes along the continuum of glycaemic control and their goals of care and to identify whether family physicians communicate the principles of regression and remission of diabetes. DESIGN: Mixed methods approach of qualitative semi-structured interviews with purposive sampling followed by cross-sectional survey of physicians. PARTICIPANTS: Thirty-three patients living with prediabetes (preDM) or type 2 diabetes mellitus (T2DM) at medical centres in Georgia and Nevada; and 387 family physicians providing primary care within the same health system. RESULTS: Patients described two timelines of diabetes: as a lifelong condition or as a condition that can be cured. Patients who perceived a lifelong condition described five treatment goals: reducing glucose-related laboratory values, losing weight, reducing medication, preventing treatment intensification and avoiding complications. For patients who perceived diabetes as a disease with an end, the goal of care was to achieve normoglycaemia. In response to patient vignettes that described potential cases of remission and regression, 38.2% of physician respondents would still communicate that a patient has preDM and 94.6% would tell the patient that he still had diabetes. CONCLUSIONS: Most physicians here exhibited reluctance to communicate remission or regression in patient care. Yet, patients describe two different potential timelines, including a subset who expect their diabetes can be 'cured'. Physicians should incorporate shared decision making to create a shared mental model of diabetes and its potential outcomes with patients. PATIENT OR PUBLIC CONTRIBUTION: In this mixed methods study, as patients participated in the qualitative phase of this study, we asked patients to tell us what additional questions we should ask in subsequent interviews. Data from this qualitative phase informed the design and interpretation of the quantitative phase with physician participants.
