A qualitative study of preoperative anxiety in orthognathic patients: The patient perspective.

Introduction: Increased preoperative anxiety may have an adverse impact on the patient experience. This qualitative study therefore aimed to explore those factors affecting anxiety in the approach to orthognathic surgery.

Methods: A total of 28 orthognathic patients who had completed their presurgical orthodontic treatment and were within 8 weeks before their surgery underwent one-to-one in-depth interviews.

Chiropractors in Multidisciplinary Teams: Enablers of Colocation Integration in GP-Led Primary Healthcare.

The aim of this study was to explore and document the enablers and barriers of chiropractic care colocation in general practice at a large-scale private primary care centre in Australia. This study focused on the perceptions of healthcare professionals regarding this integration. The research setting was a large integrated primary care centre located in an outer metro, low-socioeconomic area in the City of Moreton Bay, Queensland, Australia.

Does lower extremity alignment during normal stance predict lower limb kinematics and kinetics during drop landings?

Background: Static lower extremity alignment (LEA) during normal stance has been used clinically as a tool to determine the presence of known anterior cruciate ligament (ACL) risk factors during dynamic tasks. Previous work investigating the relationship between static LEA during normal stance and risk factors for ACL injury is limited by the use of imprecise methods or because it focuses on knee valgus only and no other potentially important variables. The aim of this investigation was to determine the relationships between static LEA and the corresponding LEA during drop landings.

Advancing Understandings of Blood Donation Motivation and Behavior.

In this review, we provide critical analysis of social science research into blood donation motivation and behavior. We first share an understanding of the existing literature and recommendations for future research collectively developed by members of the Working Group on Blood Donors and the Supply: Diversifying while Maintaining the Donor Pool, Donor Selection, and Optimizing Blood Availability and Safety, as part of the National Heart, Lung, and Blood Institute's 2022 State of the Science in Transfusion Medicine symposium. Then, rather than aim for a comprehensive treatment, we review 4 newer manuscripts that exemplify aspects of the group's recommendations and report results from countries where the blood supply is based on voluntary, nonremunerated donations.

A Cross-Sectional Study of Factors Influencing Pre-Operative Anxiety in Orthognathic Patients.

Orthognathic treatment is an important treatment modality to manage severe dentofacial discrepancies. Patients awaiting orthognathic surgery often experience increased anxiety, which may adversely affect post-operative recovery and treatment satisfaction. This study investigated the effects of a number of factors on pre-operative anxiety in orthognathic patients.

The science…or not behind deferrals of blood donors with a history of cancer.

Background: In the United States (US), each blood center's medical director sets policy for donors with a cancer history.

Study Design And Methods: A subgroup of America's Blood Centers' (ABC) Scientific, Medical, and Technical Committee developed a survey to measure the determination of eligibility, policies for deferral and/or lookback when a donor reports a current diagnosis or history of cancer. A 31-question survey was sent to 47 ABC blood centers in North America via email.

Integrity of input verbal short-term memory ability predicts naming accuracy in aphasia.

Background: Contemporary models of aphasia predominantly attribute lexical retrieval deficits to impaired access and/or maintenance of semantic, lexical, and phonological representations of words. A central hypothesis of language-emergent models of verbal short-term memory (STM) is that temporary storage and maintenance of verbal information arises from activation of linguistic representations in long-term memory. This close relationship between short-term retention and linguistic representations has prompted accounts of aphasia that include impairments to both these components.

Whole blood derived and apheresis platelets: Opinions and preferences-the results of a national survey of blood collectors.

Introduction: Currently greater than 94% of the US platelet supply is collected by apheresis. A survey to determine the attitudes of members of America's Blood Centers (ABC) toward whole blood derived (WBD) platelets was designed in light of current platelet supply issues.

Methods: An on-line survey was distributed to medical directors of the 47 ABC members.

Proceedings of the 2022 NHLBI and OASH state of the science in transfusion medicine symposium.

Background: State of the Science (SoS) meetings are used to define and highlight important unanswered scientific questions. The National Heart, Lung, and Blood Institute (NHLBI), National Institutes of Health, and the Office of the Assistant Secretary for Health (OASH), Department of Health and Human Services held a virtual SoS in transfusion medicine (TM) symposium.

Study Design And Methods: In advance of the symposium, six multidisciplinary working groups (WG) convened to define research priorities in the areas of: blood donors and the supply, optimizing transfusion outcomes for recipients, emerging infections, mechanistic aspects of components and transfusion, new computational methods in transfusion science, and impact of health disparities on donors and recipients.

The association between running volume and knee osteoarthritis prevalence: A systematic review and meta-analysis.

There is conflicting evidence regarding whether regular running is associated with knee osteoarthritis prevalence. Previous evidence reports lower knee osteoarthritis prevalence in recreational runners compared with professionals (with a higher training volume) and controls (who have a lower training volume). The aim of this systematic review and meta-analysis was to determine if weekly running volume is associated with knee osteoarthritis prevalence.

Previous experiences can influence individual cricket spin bowlers' perceptions of affordances in the performance landscape.

The ecological dynamics framework emphasises that movement solutions are guided by the relationship that exists between the performer and their environment, scaled to an individual's own action capabilities. This suggests that representative practice tasks should be used in high performance settings to encourage individually optimised movement solutions for both team and individual sports. This study specifically focuses on individual cricket spin bowlers and aims to understand the influence of their prior learning experiences on their perceptual attunement strategies when tasked with performing on a familiar Australian cricket pitch and a less familiar bespoke international (Indian) pitch.

Alternatives to common approaches for training change of direction performance: a scoping review.

Background: Research focuses heavily upon the effect of strength and power training on change of direction performance. The objective of this scoping review is to highlight alternative approaches to training change of direction.

Methods: Four databases (Scopus, PubMed, Web of Science and SPORTDiscus) were searched with no date restrictions.

Irregularly Irregular Stellate Incisions for Selective Reduction of Benign Facial Lesions.

Background: Cosmetic outcomes are among patients' top concerns when discussing treatment options for facial nevi. Benign lesions of the face often enlarge with time, and many patients seek care to minimize the perceived deformity. Complete excision remains the frontline treatment for facial lesions, but a choice must be made between the deformity from the lesion itself and scar deformity incurred from its removal.

Predictors of post-TAVI conduction abnormalities in patients with bicuspid aortic valves.

Objectives: This study evaluates predictors of conduction abnormalities (CA) following transcatheter aortic valve implantation (TAVI) in patients with bicuspid aortic valves (BAV).

Background: TAVI is associated with CA that commonly necessitate a permanent pacemaker. Predictors of CA are well established among patients with tricuspid aortic valves but not in those with BAV.

Semantic flow and its relation to controlled semantic retrieval deficits in the narrative production of people with aphasia.

Aphasia has had a profound influence on our understanding of how language is instantiated within the human brain. Historically, aphasia has yielded an in vivo model for elucidating the effects of impaired lexical-semantic access on language comprehension and production. Aphasiology has focused intensively on single word dissociations.

There is No "Axillary Tail": Rethinking the Assumption of James Spence.

Widely quoted, "the axillary tail of Spence" refers to a contiguous extension of adipose angling superolaterally from the primary breast into the axilla. Described anecdotally in 1871, the "tail of Spence" has been considered important to the fields of general surgery, oncology, plastic surgery, and anatomy ever since. Despite the ubiquitous presence of the concept in literature, clinical discussions, and educational settings, we argue against the very existence of Spence's "tail.

Long-term Return to Sports After Anterior Cruciate Ligament Injury: Reconstruction vs No Reconstruction-A Comparison of 2 Case Series.

Background: Reconstruction is considered to provide the best opportunity for return to sports (RTS) after anterior cruciate ligament (ACL) rupture. However, recent studies report that <50% of athletes return to preinjury sporting levels and that RTS rates at 1 year after injury are the same for athletes undergoing reconstruction and nonoperative management. Long-term studies are essential to confirm these findings and guide decisions regarding surgery.

Impact of COVID-19 pandemic on the management of nonculprit lesions in patients presenting with ST-elevation myocardial infarction: Outcomes from the pan-London heart attack centers.

Background: The impact of COVID-19 on the diagnosis and management of nonculprit lesions remains unclear.

Objectives: This study sought to evaluate the management and outcomes of patients with nonculprit lesions during the COVID-19 pandemic.

Methods: We conducted a retrospective observational analysis of consecutive primary percutaneous coronary intervention (PPCI) pathway activations across the heart attack center network in London, UK.

Validation of a Smartwatch-Based Workout Analysis Application in Exercise Recognition, Repetition Count and Prediction of 1RM in the Strength Training-Specific Setting.

The goal of this study was to assess the validity, reliability and accuracy of a smartwatch-based workout analysis application in exercise recognition, repetition count and One Repetition Maximum (1RM) prediction in the strength training-specific setting. Thirty recreationally trained athletes performed four consecutive sets of barbell deadlift, barbell bench press and barbell back squat exercises with increasing loads from 60% to 80% of their estimated 1RM with maximum lift velocity. Data was measured using an Apple Watch Sport and instantaneously analyzed using an iOS workout analysis application called StrengthControl.

Reliability of the ForceFrame With and Without a Fixed Upper-Limb Mold in Shoulder Rotation Strength Assessments Compared With Traditional Hand-Held Dynamometry.

Context: An imbalance between shoulder internal rotation (IR) and external rotation (ER) strength in athletes is proposed to increase the risk of sustaining a shoulder injury. Hand-held (HHD) and externally fixed dynamometry are reliable forms of assessing shoulder IR and ER strength. A new externally fixed device with an attachable fixed upper-limb mold (The ForceFrame) exists; however, its reliability in measuring shoulder strength is yet to be investigated.
