Knee4Life: Empowering Knee Recovery After Total Knee Replacement Through Digital Health Protocol.

Pain and knee stiffness are common problems following total knee replacement surgery, with 10-20% of patients reporting dissatisfaction following their procedure. A remote assessment of knee stiffness could improve outcomes through continuous monitoring, facilitating timely intervention. Using machine learning algorithms, computer vision can extract joint angles from video footage, offering a method to monitor knee range of motion in patients' homes.

In-shoe plantar shear stress sensor design, calibration and evaluation for the diabetic foot.

Plantar shear stress may have an important role in the formation of a Diabetic Foot Ulcer, but its measurement is regarded as challenging and has limited research. This paper highlights the importance of anatomical specific shear sensor calibration and presents a feasibility study of a novel shear sensing system which has measured in-shoe shear stress from gait activity on both healthy and diabetic subjects. The sensing insole was based on a strain gauge array embedded in a silicone insole backed with a commercial normal pressure sensor.

The WSM completed the following: ) 3.0-T MRI scans, to determine the volume of 22 individual lower limb muscles, 5 functional muscle groups, patellar tendon (PT) cross-sectional area (CSA), and PT moment arm; and ) countermovement jumps (CMJ) and isometric midthigh pull (IMTP) contractions.

Smaller Biceps Femoris Aponeurosis Size in Legs with a History of Hamstring Strain Injury.

Biceps femoris long head (BF) aponeurosis size was compared between legs with and without prior hamstring strain injury (HSI) using two approaches: within-group (injured vs. uninjured legs of previous unilateral HSI athletes) and between-group (previously injured legs of HSI athletes vs. legs of No Prior HSI athletes).

Impact of Insurance Type on Access to Pediatric Surgical Care.

Background: This study aimed to measure the impact of insurance type on access to pediatric surgical care, clinical and surgical scheduling decisions, provider-driven cancelations, and missed care opportunities (MCOs). We hypothesize that patients with public health insurance experience longer scheduling delays and more frequently canceled surgical appointments compared with patients with private health insurance.

Methods: This retrospective study reviewed the demographics and clinical characteristics of patients who underwent a surgical procedure within the plastic and oral surgery department at our institution in 2019.

The effect of calcaneus and metatarsal head offloading insoles on healthy subjects' gait kinematics, kinetics, asymmetry, and the implications for plantar pressure management: A pilot study.

Background: The global number of people with diabetes is estimated to reach 643 million by 2030 of whom 19-34% will present with diabetic foot ulceration. Insoles which offload high-risk ulcerative regions on the foot, by removing insole material, are the main contemporary conservative treatment to maintain mobility and reduce the likelihood of ulceration. However, their effect on the rest of the foot and relationship with key gait propulsive and balance kinematics and kinetics has not been well researched.

Sex differences in muscle morphology between male and female sprinters.

There is a marked difference between males and females in sprint running performance, yet a comprehensive investigation of sex differences in the muscle morphology of sprinters, which could explain the performance differences, remains to be completed. This study compared muscle volumes of 23 individual leg muscles and 5 functional muscle groups, assessed with 3 T magnetic resonance imaging, between male ( = 31) and female ( = 22) sprinters, as well as subgroups of elite males (EM, = 5), elite females (EF, = 5), and performance-matched (to elite females) males (PMM, = 6). Differences in muscle volume distribution between EM, EF, and unathletic male (UM) controls were also assessed.

Successful de-implementation of an ineffective practice: The fall of docusate.

Background: Reducing wasteful practices optimizes value in medicine. Docusate lacks treatment efficacy yet is widely prescribed. This quality improvement project aimed to de-implement docusate in place of a new evidence-based order set.

The Effect of Specific Bioactive Collagen Peptides on Tendon Remodeling during 15 wk of Lower Body Resistance Training.

Purpose: Collagen peptide supplementation has been reported to enhance synthesis rates or growth in a range of musculoskeletal tissues and could enhance tendinous tissue adaptations to resistance training (RT). This double-blind placebo-controlled study aimed to determine if tendinous tissue adaptations, size (patellar tendon cross-sectional area (CSA) and vastus lateralis (VL) aponeurosis area), and mechanical properties (patellar tendon), after 15 wk of RT, could be augmented with collagen peptide (CP) versus placebo (PLA) supplementation.

Methods: Young healthy recreationally active men were randomized to consume either 15 g of CP ( n = 19) or PLA ( n = 20) once every day during a standardized program of lower-body RT (3 times a week).

Conducting a full-scale emergency management exercise during COVID-19: A case study of Puyallup Chill Out 2021.

The COVID-19 public health emergency severely limited the ability of emergency managers to conduct emergency exercises, particularly at the functional or full-scale level. Throughout the COVID-19 pandemic response, other emergencies continued, and local emergency management was called to respond, ensuring that local guidelines and COVID-19 restrictions were observed. This paper describes how the pandemic impacted on the City of Puyallup's emergency management training and exercise programme and how the City adapted to conduct a full-scale exercise in the autumn of 2021.

Risk Factors Associated with Severe Macromastia among Adolescents and Young Women.

Background: Macromastia is common among adolescents and young women and has well-documented negative physical and psychosocial effects. The pathogenesis of idiopathic macromastia has been attributed to increased end organ sensitivity to circulating gonadal hormones. Despite the known negative effects of macromastia, there is a paucity of literature examining the clinical risk factors associated with macromastia severity in this age group.

The Impact of Combined Oral Contraceptives on Adolescents with Macromastia.

Background: The combined oral contraceptive pill, containing both estrogen and progestin, is commonly prescribed to adolescents for numerous health benefits. However, there is concern among patients and providers that its use may exacerbate breast growth. This retrospective, case-control study examined the association between combined oral contraceptive pill use and macromastia-related breast hypertrophy and symptoms in adolescents.

Unlabelled: Evidence-based protocols identifying COVID-19 cases in pediatric preoperative settings are lacking. With COVID-19 positioned to remain a threat to children, this study examines effectiveness of preoperative COVID-19 symptom screening in pediatric patients.

Methods: This retrospective cohort study included hospital billing/medical record queries of (1) procedures performed under conscious sedation/general anesthesia and (2) laboratory-confirmed COVID-19 (+) cases from April 6, 2020, to June 15, 2020.

Extending the theory of planned behaviour to investigate the issue of microplastics in the marine environment.

The attention to microplastics and the consequences of its presence in the marine environment is increasing in scientific fields as well as on common media channels. In the absence of regulation in many countries, manufacturers are not required to exclude microplastic from their products, however consumers could force the production in a more sustainable direction with their choices. This study demonstrates the utility of the Theory of Planned Behaviour (TPB) in understanding the publics' intention to avoid buying products which contain microplastics.

Effect of long-term maximum strength training on explosive strength, neural, and contractile properties.

The purpose of this cross-sectional study was to compare explosive strength and underpinning contractile, hypertrophic, and neuromuscular activation characteristics of long-term maximum strength-trained (LT-MST; ie, ≥3 years of consistent, regular knee extensor training) and untrained individuals. Sixty-three healthy young men (untrained [UNT] n = 49, and LT-MST n = 14) performed isometric maximum and explosive voluntary, as well as evoked octet knee extension contractions. Torque, quadriceps, and hamstring surface EMG were recorded during all tasks.

Enablers and barriers to COVID-19 vaccine uptake: An international study of perceptions and intentions.

The development of COVID-19 vaccines is occurring at unprecedented speeds, but require high coverage rates to be successful. This research examines individuals' psychological beliefs that may act as enablers and barriers to vaccination intentions. Using the health beliefs model as a guide to our conceptual framework, we explore factors influencing vaccine hesitancy and health beliefs regarding risks and severity of the disease, along with individual variables such as income, age, religion, altruism, and collectivism.

Predictors of Nonseroconversion after SARS-CoV-2 Infection.

Not all persons recovering from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection develop SARS-CoV-2-specific antibodies. We show that nonseroconversion is associated with younger age and higher reverse transcription PCR cycle threshold values and identify SARS-CoV-2 viral loads in the nasopharynx as a major correlate of the systemic antibody response.

Neural adaptations to long-term resistance training: evidence for the confounding effect of muscle size on the interpretation of surface electromyography.

This study compared elbow flexor (EF; ) and knee extensor (KE; ) maximal compound action potential (M) amplitude between long-term resistance trained (LTRT; = 15 and = 14, 6 ± 3 and 4 ± 1 yr of training) and untrained (UT; = 14 and = 49) men, and examined the effect of normalizing electromyography (EMG) during maximal voluntary torque (MVT) production to M amplitude on differences between LTRT and UT. EMG was recorded from multiple sites and muscles of EF and KE, M was evoked with percutaneous nerve stimulation, and muscle size was assessed with ultrasonography (thickness, EF) and magnetic resonance imaging (cross-sectional area, KE). Muscle-electrode distance (MED) was measured to account for the effect of adipose tissue on EMG and M.
