Comparison of Functional Outcomes after Anterior Cruciate Ligament Reconstruction with Meniscal Repair for Unstable versus Stable Meniscal Tears. Diagnostics (Basel) 2024; 14:871. [PMID: 38732286 PMCID: PMC11083838 DOI: 10.3390/diagnostics14090871] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 04/15/2024] [Accepted: 04/19/2024] [Indexed: 05/13/2024] Open
Abstract
This study aimed to compare functional outcomes including knee muscle strength in the quadriceps and hamstrings, and proprioception, assessed through dynamic postural stability (overall stability index [OSI]) and self-reported outcomes in the operated and non-operated knees between anterior cruciate ligament reconstruction (ACLR) with meniscal repair for unstable (root and radial tears) and stable (longitudinal, horizontal, and bucket handle tears) meniscal tears. A total of 76 patients were randomly selected (41 with ACLR with meniscal repair for unstable meniscal tears and 35 with ACLR with meniscal repair for stable meniscal tears) at three different time points (preoperative, 6 months, and 12 months). Repeated measures analysis of variance was used to investigate the differences in outcomes for between-subject and within-subject factors. In the operated knees, there were no significant differences for functional outcomes between the two groups (all p > 0.05). In the non-operated knees, a significant difference was observed for the OSI between the two groups, which was significantly higher in ACLR with meniscal repair for unstable meniscal tears than for stable meniscal tears at 6 months (p < 0.001). Multiple linear regression analysis showed that age (p = 0.027), preoperative OSI in the operated knees (p = 0.005), and postoperative OSI in the operated knees at 6 months (p = 0.002) were significant and independent predictors for OSI in the non-operated knees at 6 months postoperatively. Therefore, while no differences were observed in functional outcomes between the two groups in the operated knees, dynamic postural stability was poorer at 6 months postoperatively in the non-operated knees of patients with ACLR with meniscal repair for unstable meniscal tears. Furthermore, a significant correlation was observed between preoperative/postoperative dynamic postural stability in the operated knees and postoperative dynamic postural stability in the non-operated knees. Hence, we recommend incorporating balance exercises for both knees in post-surgical rehabilitation, particularly for patients with unstable meniscal tears.

Patient-reported outcomes during telehealth versus in-person follow-up visits for patients treated with extracorporeal shockwave therapy. PM R 2024; 16:323-330. [PMID: 37574919 DOI: 10.1002/pmrj.13057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/02/2023] [Accepted: 07/28/2023] [Indexed: 08/15/2023]
Abstract
BACKGROUND The limited research describing clinical outcomes using telehealth for management of musculoskeletal conditions is primarily within orthopedic surgery care. OBJECTIVE To characterize differences in patient reported outcomes using telehealth compared with in-person follow-up visits in patients with Achilles tendinopathy (AT) or plantar fasciitis (PF) treated using extracorporeal shockwave therapy (ESWT). DESIGN Retrospective chart review. SETTING Outpatient sports medicine clinic. PATIENTS 82 patients with AT and 46 patients with PF. INTERVENTIONS In-person (n = 76) and telehealth (n = 52) follow-up visits. MAIN OUTCOME MEASUREMENTS Victorian Institute of Sports Assessment-Achilles (VISA-A) for AT and Foot and Ankle Ability Measure (FAAM) for PF as well as billing level. RESULTS There was significant improvement from baseline to final VISA-A (p < .01) and FAAM (p < .01) following ESWT. No significant difference existed in the proportion of patients who met the minimal clinically important difference based on in-person (71.1%) versus telehealth (71.2%) follow-up (p = .99). The in-person group demonstrated higher billing levels compared to the telehealth group (Level: 3.5 ± 0.6 vs. 2.8 ± 0.7, p < .01). CONCLUSIONS Given no significant differences in outcomes between two modes of follow-ups, telehealth may serve as an alternative method to guide management of musculoskeletal injuries with ESWT and other procedures.

Defining Clinically Meaningful Cut Points for Leg Power Impairment Using Physical Performance in Older Adults: A Secondary Analysis From Boston RISE. Arch Phys Med Rehabil 2024; 105:690-695. [PMID: 37769931 PMCID: PMC10965500 DOI: 10.1016/j.apmr.2023.09.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 09/05/2023] [Accepted: 09/06/2023] [Indexed: 10/03/2023]
Abstract
OBJECTIVE To identify clinically meaningful thresholds of leg power impairment identified by the stair climb power test (SCPT). DESIGN Cross-sectional analysis using the baseline data from an observational cohort study. SETTING The Boston Rehabilitative Impairment Study of the Elderly. PARTICIPANTS Community-dwelling older adults (N=413). MAIN OUTCOME MEASURES SCPT and the Short Physical Performance Battery (SPPB). RESULTS Using the receiver operating characteristic curves and Youden's J statistics, the optimal threshold for the SCPT associated with mobility limitation as defined by an SPPB score ≤9 was 3.07 Watts/kg for men with a sensitivity of 74%, a specificity of 73% and, an area under the curve (AUC) value of 0.78. For women, the optimal threshold was 2.59 Watts/kg with a sensitivity of 83%, a specificity of 69%, and an AUC value of 0.81. The classification and regression tree sensitivity analysis demonstrated similar thresholds, 2.88 Watts/kg and 2.53 Watts/kg for men and women, respectively. CONCLUSIONS The study identified clinically meaningful thresholds of impairment for the SCPT for mobility limited older primary care patients. These thresholds may be used to inform rehabilitation care to improve functional mobility of older adults and should be validated in larger more representative clinical trials.

Nonsteroidal Anti-Inflammatory Drug Injections versus Steroid Injections in the Management of Upper and Lower Extremity Orthopedic Conditions: A Systematic Review with Meta-Analysis. J Clin Med 2024; 13:1132. [PMID: 38398445 PMCID: PMC10889729 DOI: 10.3390/jcm13041132] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Revised: 01/31/2024] [Accepted: 02/14/2024] [Indexed: 02/25/2024] Open
Abstract
BACKGROUND Although corticosteroid injections are an effective treatment for musculoskeletal pathologies, they may not be suitable for all patients. The purpose of this systematic review was to compare clinical outcomes between patients who received NSAID and corticosteroid injections for various orthopedic conditions. METHODS Medline, Embase, Web of Science, and Cochrane Central Register of Controlled Trials were searched, and meta-analyses were performed using a random-effects model for outcomes presented in three or more studies. Other studies were qualitatively analyzed. RESULTS A total of 28 articles with 2113 patients were included. A meta-analysis of five studies in patients with shoulder impingement syndrome demonstrated that there was no significant difference in the pain visual analogue scale (VAS) between subacromial NSAID injections and corticosteroid injections at 1 month [weighted mean difference (WMD) -0.244; 95% CI, -1.232 to 0.745; I2, 94.5%]. For patients with knee osteoarthritis, a meta-analysis of three studies demonstrated that there was no significant difference between intraarticular NSAID injections and corticosteroid injections in pain VAS at 1 month (WMD 0.754; 95% CI, -0.413 to 1.921; I2, 90.2%) and 3 months (WMD-0.089; 95% CI, -0.345 to 0.166; I2, 0%). A review of the studies assessing pain outcomes for hip osteoarthritis, adhesive capsulitis, and plantar fasciitis showed no significant differences between the NSAID and corticosteroid groups. CONCLUSION NSAID injections may be safe and effective alternatives to steroid injections, especially in shoulder impingement syndrome and knee osteoarthritis.

Abstract
OBJECTIVE To determine the efficacy of extracorporeal shockwave therapy (ESWT) and investigate outcomes following the use of ESWT for athletes and physically active individuals. DESIGN Systematic review. DATA SOURCES We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses and searched four databases: PubMed (NLM), Embase (Elsevier), CINAHL Complete (EBSCO) and Web of Science (Clarivate). ELIGIBILITY CRITERIA FOR SELECTING STUDIES Included studies were randomised controlled trials, cohort and case-control studies, cases series and reports that evaluated outcomes following ESWT for athletes, physically active individuals and occupational groups requiring regular physical activity such as military cadets. RESULTS 56 studies with 1874 athletes or physically active individuals were included. Using the Oxford level of evidence rating, included studies were 18 level I (32.1%), 3 level II (5.4%), 10 level III (17.9%), 13 level IV (23.2%) and 12 level V (21.4%). Based on the level I studies, ESWT may be effective alone in plantar fasciitis, lateral epicondylitis and proximal hamstring tendinopathy and as an adjunct to exercise treatment in medial tibial stress syndrome and osteitis pubis in athletes or physically active individuals. In most studies, athletes were allowed to continue activities and training and tolerated ESWT with minimal side effects. CONCLUSION ESWT may offer an efficacious treatment alone or as an adjunct to concurrent exercise therapy in selected sports-related injuries and without major adverse events. Further high-level research is needed to better define the role and clinical outcomes of ESWT.

Abstract
BACKGROUND Total ankle arthroplasty (TAA) has higher complication and failure rates compared to other surgical joint replacement procedures despite technological advances. This study aimed to find the long-term survivability of the TAA procedure and identify the patient risk factors for failure with one of the largest cohorts of patients in the literature. METHODS This retrospective cohort study involving cases between 2007 and 2018 analyzed patients who received an index primary TAA procedure in Korea. A total of 5619 cases were included in the final analysis. The TAA failure was defined as either a case with revision arthroplasty or a case with TAA implant removal and arthrodesis performed after primary TAA. RESULTS During the study period, the 5-year survival rate was 95.4% (95% CI, 94.7-96.1%), and the 10-year survival rate was 91.1% (95% CI, 89.1-93.1%). A younger age (<55 years, adjusted hazard ratio [AHR], 1.725; 55-64 years, AHR, 1.812; p < 0.001 for both), chronic pulmonary disease (AHR, 1.476; p = 0.013), diabetes (AHR, 1.443; p = 0.014), and alcohol abuse (AHR, 1.524; p = 0.032) showed a significantly high odds ratio for primary TAA failure in Cox regression analysis. CONCLUSION The 10-year TAA survivorship rate was 91.1%. A younger age, chronic pulmonary disease, diabetes, and heavy alcohol consumption are risk factors for TAA.

Effect of Adding Kinesio Taping to Exercise Therapy in the Treatment of Patellofemoral Pain Syndrome. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:medicina59040754. [PMID: 37109711 PMCID: PMC10142653 DOI: 10.3390/medicina59040754] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 04/09/2023] [Accepted: 04/10/2023] [Indexed: 04/29/2023]
Abstract
Background and objectives: Patellar taping has been widely used for the primary or adjunctive treatment of patellofemoral pain syndrome (PFPS); however, there are limited data in terms of functional outcomes. This study aimed to investigate whether there is any beneficial effect of adding Kinesio Taping® (KT) to exercise therapy in the treatment of PFPS. Materials and Methods: Twenty patients (27.5 ± 5.4 years) with PFPS who applied KT and 19 patients (27.3 ± 7.4 years) who did not were included in this study. Quadriceps muscle strength and acceleration time (AT) were assessed using an isokinetic device. Patient-reported outcomes were evaluated using the Kujala anterior knee pain scale (AKPS). Both groups underwent one-month exercise therapy. Results: There was no significant difference in quadriceps strength, AT, and AKPS at baseline and at 1 month between the taping and non-taping groups (p > 0.05). However, for quadriceps muscle strength, the effect of time*group interaction was statistically significant (F(1.37) = 4.543, p < 0.05, partial eta squared 0.109), showing that improvement in the quadriceps strength was higher in the non-taping group than that in the taping group. Conclusions: Adding KT to exercise therapy did not elicit extra benefits in quadriceps muscle strength and AT, and AKPS among PFPS with abnormal patellar tracking at one month.

Abstract
Wearable devices capable of measuring gait parameters may provide a means to more economical gait analysis compared to conventional equipment comprising of a motion capture system and a forced treadmill. Beflex Coach (Beflex, Republic of Korea) is one such device but worn on the ear as Bluetooth earphones, unlike other wearables worn on the wrist, feet, or torso. In this study, the validity of the device was examined against a motion capture system and a forced treadmill for walking and running parameters. Five walking parameters (cadence, single support time, double support time, vertical oscillation (VO), and instantaneous vertical loading rate (IVLR)) and six running parameters (cadence, stance time, flight time, peak force, VO, and IVLR) were studied. Twenty young adults participated in walking or running on a forced treadmill at different speeds (walking: 0.8, 1.25, and 1.7 m/s for walking; running: 2, 2.5, and 3 m/s) while the two systems operated simultaneously. As a result, all parameters showed excellent associations (ICC > 0.75) and good agreements in Bland-Altman plots. The results of the study support the potential use of the ear-worn device as an inexpensive gait analysis equipment.

Characteristics and Future Direction of Tibialis Posterior Tendinopathy Research: A Scoping Review. Medicina (B Aires) 2022; 58:medicina58121858.

Abstract
Background and Objectives: Tibialis posterior tendon pathologies have been traditionally categorized into different stages of posterior tibial tendon dysfunction (PTTD), or adult acquired flatfoot deformity (AAFD), and more recently to progressive collapsing foot deformity (PCFD). The purpose of this scoping review is to synthesize and characterize literature on early stages of PTTD (previously known as Stage I and II), which we will describe as tibialis posterior tendinopathy (TPT). We aim to identify what is known about TPT, identify gaps in knowledge on the topics of TPT, and propose future research direction. Materials and Methods: We included 44 studies and categorized them into epidemiology, diagnosis, evaluation, biomechanics outcome measure, imaging, and nonsurgical treatment. Results: A majority of studies (86.4%, 38 of 44 studies) recruited patients with mean or median ages greater than 40. For studies that reported body mass index (BMI) of the patients, 81.5% had mean or median BMI meeting criteria for being overweight. All but two papers described study populations as predominantly or entirely female gender. Biomechanical studies characterized findings associated with TPT to include increased forefoot abduction and rearfoot eversion during gait cycle, weak hip and ankle performance, and poor balance. Research on non-surgical treatment focused on orthotics with evidence mostly limited to observational studies. The optimal exercise regimen for the management of TPT remains unclear due to the limited number of high-quality studies. Conclusions: More epidemiological studies from diverse patient populations are necessary to better understand prevalence, incidence, and risk factors for TPT. The lack of high-quality studies investigating nonsurgical treatment options is concerning because, regardless of coexisting foot deformity, the initial treatment for TPT is typically conservative. Additional studies comparing various exercise programs may help identify optimal exercise therapy, and investigation into further nonsurgical treatments is needed to optimize the management for TPT.

Abstract
Pulse-wave velocity (PWV) is a widely used clinical marker of arterial stiffness. Associations between several physical fitness measures and arterial stiffness have been examined. However, these results were inconsistent. Therefore, we conducted a cross-sectional study to assess the relationship between various physical fitness parameters and arterial stiffness in older adults. From January 2014 to December 2015, 1500 participants (men, n = 587; mean age, 71.78 ± 5.10 years) in South Korea were enrolled in the study. Koreans aged >65 years who agreed to participate in the study were enrolled. Individuals who were unable to exercise because of underlying conditions were excluded. VO2 max (mL/kg/min), handgrip strength (kg), handgrip strength (kg)/body weight (kg) ratio, one-leg standing time (s), and 10-meter walking speed (m/s) were measured. The brachial-ankle pulse wave velocity (baPWV) was measured using a VP-1000 instrument. VO2 max (mL/kg/min), handgrip (kg)/body weight (kg) ratio, one-leg standing time (s), and 10-meter walking speed (m/s) were significantly inversely associated with baPWV. This association was consistent even after adjusting for confounding factors. Our study revealed a significant association between various aspects of physical fitness and arterial stiffness. This study suggests that physical fitness is a useful predictor of arterial stiffness in older adults.

Abstract
OBJECTIVE To explore the association of physical activity (PA) with musculoskeletal pain (MSK pain). DESIGN Cross-sectional study SETTING: 14 countries (Argentina, Australia, Austria, Brazil, Chile, France, Germany, Italy, the Netherlands, Singapore, South Africa, Spain, Switzerland and the USA). PARTICIPANTS Individuals aged 18 or older. PRIMARY AND SECONDARY OUTCOME MEASURES PA volumes were assessed with an adapted version of the Nordic Physical Activity Questionnaire-short. Prevalence of MSK pain was captured by means of a 20-item checklist of body locations. Based on the WHO recommendation on PA, participants were classified as non-compliers (0-150 min/week), compliers (150-300 min/week), double compliers (300-450 min/week), triple compliers (450-600 min/week), quadruple compliers (600-750 min/week), quintuple compliers (750-900 min/week) and top compliers (more than 900 min/week). Multivariate logistic regression was used to obtain adjusted ORs of the association between PA and MSK pain for each body location, correcting for age, sex, employment status and depression risk. RESULTS A total of 13 741 participants completed the survey. Compared with non-compliers, compliers had smaller odds of MSK pain in one location (thoracic pain, OR 0.77, 95% CI 0.64 to 0.93). Double compliance was associated with reduced pain occurrence in six locations (elbow, OR 0.70, 95% CI 0.50 to 0.98; forearm, OR 0.63, 95% CI 0.40 to 0.99; wrist, OR 0.74, 95% CI 0.57 to 0.98; hand, OR 0.57, 95% CI 0.40 to 0.79; fingers, OR 0.72, 95% CI 0.52 to 0.99; abdomen, OR 0.61, 95% CI 0.41 to 0.91). Triple to top compliance was also linked with lower odds of MSK pain (five locations in triple compliance, three in quadruple compliance, two in quintuple compliance, three in top compliance), but, at the same time, presented increased odds of MSK pain in some of the other locations. CONCLUSION A dose of 300-450 min WHO-equivalent PA/week was associated with lower odds of MSK pain in six body locations. On the other hand, excessive doses of PA were associated with higher odds of pain in certain body locations.

Abstract
Despite remarkable improvements in clinical outcomes after anterior cruciate ligament reconstruction, the residual rotational instability of knee joints remains a major concern. The anterolateral ligament (ALL) has recently gained attention as a distinct ligamentous structure on the anterolateral aspect of the knee joint. Numerous studies investigated the anatomy, function, and biomechanics of ALL to establish its potential role as a stabilizer for anterolateral rotational instability. However, controversies regarding its existence, prevalence, and femoral and tibial insertions need to be addressed. According to a recent consensus, ALL exists as a distinct ligamentous structure on the anterolateral aspect of the knee joint, with some anatomic variations. The aim of this article was to review the updated anatomy of ALL and present the most accepted findings among the existing controversies. Generally, ALL originates slightly proximal and posterior to the lateral epicondyle of the distal femur and has an anteroinferior course toward the tibial insertion between the tip of the fibular head and Gerdy’s tubercle below the lateral tibial plateau.

Abstract
The relationship between hyperhomocysteinemia (HHcy) and obesity with low skeletal muscle mass (LMM) has not been established. We aim to assess the association between HHcy and the coexistence of obesity and LMM in asymptomatic adult population. We conducted a population-based cross-sectional study among asymptomatic individuals who underwent measurements of plasma homocysteine and body composition analysis. HHcy was defined as > 15 umol/L, obesity as body mass index ≥ 25 (kg/m2), and LMM as skeletal muscle index less than 2 SD below the sex-specific mean of young adults. The participants were classified into ‘control’, ‘obesity alone’, ‘LMM alone’, and ‘obesity with LMM’. Among 113,805 participants, the prevalence of HHcy was 8.3% in control, 8.7% in obesity alone, 10.0% in LMM alone, and 13.0% in obesity with LMM (p for trend < 0.001). In a multivariable logistic regression analysis, the associations showed a positive trend for HHcy along the groups from obesity alone, to LMM alone, and to obesity with LMM. HHcy was independently associated with the presence of LMM alone (adjusted odds ratio 1.186 [95% confidence interval 1.117–1.259]) and obesity with LMM (1.424 [1.134–1.788]), respectively. This study demonstrated that HHcys was more strongly associated with coexistence of obesity and LMM than either condition alone in the adult population.

Abstract
Social support, multimorbidity, and functional status are important determinants of health in older adults, but their prognostic implications remain unclear after an acute illness. We conducted a prospective cohort study of 201 patients 65 years or older who were hospitalized for pneumonia at a university hospital in Korea in 2019-2020. K-means cluster analysis was performed using social deprivation score (range: 0-5), activities of daily living (range: 0-7), instrumental activities of daily living (range: 0-7), physical limitation score (range: 0-7), and Gagne comorbidity index (range: 0-24) (higher scores indicate higher risk). Four groups were identified: 1) Group A: physically limited and non-disabled group with limited social support; 2) Group B: multimorbid but functional group with social support; 3) Group C: multimorbid and disabled group with social support; 4) Group D: multimorbid and disabled group with limited social support. For Groups A through D, the Kaplan-Meir estimates for 6-month mortality were 10.0%, 18.0%, 34.2%, and 43.6%, respectively, and the 6-month mean survival times were 166.4 days (95% CI: 156.1-176.6), 156.9 days (95% CI: 140.8-173.1), 145.2 days (95% CI: 126.6-163.8), and 125.9 days (95% CI: 107.7-144.1), respectively. After adjusting for sex, age, and pneumonia severity score, the hazard ratios for Groups B through D versus Group A were 2.07 (95% CI: 0.70-6.13), 3.14 (95% CI: 1.17-8.42), and 4.38 (95% CI: 1.73-11.04), respectively. Our results suggest that multimorbidity and disabilities were implicated in higher risk of 6-month mortality after pneumonia, and social support may mitigate this risk among those with multimorbidity and disability.

Abstract
Little is known about how social determinants, comorbidity, and disability status are associated with functional recovery after an acute illness. A prospective cohort study was conducted between 2019-2020 at a university hospital in Korea, to investigate functional recovery after hospitalization for pneumonia in older adults with different degrees of social deprivation, disabilities, and comorbidities. K-means cluster analysis was used to identify groups of patients based on social deprivation score, activities of daily living, instrumental activities of daily living, physical limitation score, and Gagne comorbidity index. Four groups were identified: Group A: non-disabled group with limited social support (n=61 [30.3%]); Group B: multimorbid but non-disabled group with social support (n=45 [22.4%]); Group C: multimorbid and disabled group with social support (n=38 [18.9%]); Group D: multimorbid and disabled group with limited social support (n=57 [28.4%]). Functional status, defined as ability to perform 21 activities and physical tasks independently, was measured via telephone interviews at 1, 3, and 6 months after discharge. Group-based trajectory model identified four functional status trajectories: excellent (n=29 [14.4%]), good (n=51 [25.4%]), fair (n=58 [28.9%]) and poor (n=63 [31.3%]). The most common functional trajectory by four groups was good trajectory (59%) in Group A, excellent trajectory (48.9%) in Group B, fair (50%) and poor trajectory (50%) in Group C, and poor trajectory (77.2%) in Group D. Our results suggest that most patients without disability recover functional status after pneumonia, despite multimorbidity or limited social support. Social support seems to be more important for those with multimorbidity and disability.

A Systematic Review of Systematic Reviews on the Epidemiology, Evaluation, and Treatment of Plantar Fasciitis. Life (Basel) 2021; 11:life11121287. [PMID: 34947818 PMCID: PMC8705263 DOI: 10.3390/life11121287] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2021] [Revised: 11/17/2021] [Accepted: 11/19/2021] [Indexed: 12/20/2022] Open
Abstract
The number of systematic review and meta-analyses on plantar fasciitis is expanding. The purpose of this review was to provide a comprehensive summary of reviews on the topic pertaining to plantar fasciitis, identify any conflicting and inconsistent results, and propose future research direction. A qualitative review of all systematic reviews and meta-analyses related to plantar fasciitis up to February 2021 was performed using PubMed, Embase, Web of Science, and the Cochrane Database. A total of 1052 articles were initially identified and 96 met the inclusion criteria. Included articles were summarized and divided into the following topics: epidemiology, diagnosis, and treatment. While the majority of reviews had high level of heterogeneity and included a small number of studies, there was general consensus on certain topics, such as BMI as a risk factor for plantar fasciitis and extracorporeal shockwave therapy as an effective mode of therapy. A qualitative summary of systematic reviews and meta-analyses published on plantar fasciitis provides a single source of updated information for clinicians. Evidence on topics such as the epidemiology, exercise therapy, or cost-effectiveness of treatment options for plantar fasciitis are lacking and warrant future research.

Abstract
Creation of guidelines and education on digital professionalism have been sluggish despite the ever-increasing use of social media by digitally native medical students, who are at risk of blurring the line between their professional and personal lives online. A qualitative thematic analysis was applied on 79 videos extracted from 70,154 YouTube videos uploaded by Korean medical students between March and April 2020. We found 20% contained at least one concerning behavior themed under 'failure to engage,' 'disrespectful behaviors,' or 'poor self-awareness.' Professional lapses identified were classified into seriousness levels. Mostly were "controversial' or 'concerning' but some 'highly concerning' contents were also found. This is the first study on digital professionalism behavior on medical students' YouTube videos. The potential negative impact on the medical profession of the easily accessible public online videos cannot be ignored and thus we suggest the need for them to be taken more seriously.

Comparison of Frailty Index to Pneumonia Severity Measures in Older Patients With Pneumonia. J Am Med Dir Assoc 2021; 23:165-169. [PMID: 34624243 DOI: 10.1016/j.jamda.2021.08.044] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 08/20/2021] [Accepted: 08/31/2021] [Indexed: 01/06/2023]
Abstract
OBJECTIVES Risk stratification tools are useful to provide appropriate clinical care for older patients with pneumonia. This study aimed to compare a Frailty Index (FI) with pneumonia severity measures, CURB-65, and the Pneumonia Severity Index (PSI), for predicting mortality and persistent disability after pneumonia. DESIGN Single-center prospective cohort study. SETTING AND PARTICIPANTS The study included 190 patients aged ≥65 years who were hospitalized with pneumonia at a university hospital in Korea between October 2019 and September 2020. METHODS At admission, a 50-item deficit-accumulation FI (range: 0-1), CURB-65 (range: 0-5), and PSI (range: 0-395) scores were calculated. The outcomes were death and a composite outcome of death or decline in ability to perform daily activities and physical task 6 months later. RESULTS The median age was 79 years (interquartile range: 74-85), and 70 (36.8%) patients were women. The patients who died (n = 53) had higher FI (median, 0.46 vs 0.20; P < .011), CURB-65 score (median, 3 vs 2; P = .001), and PSI score (median, 149 vs 116; P < .001) than those who did not. The C-statistics (95% confidence intervals) for 6-month mortality were 0.69 (0.61-0.77) for the FI, 0.62 (0.53-0.71) for CURB-65, and 0.71 (0.62-0.79) for the PSI (P = .019). The C-statistics for the 6-month composite outcome were 0.73 (0.65-0.81) for the FI, 0.64 (0.55-0.73) for CURB-65, and 0.69 (0.60-0.77) for the PSI (P = .096). The C-statistics improved when the FI was added to CURB-65 (from 0.64 to 0.74; P = .003) and to the PSI (from 0.69 to 0.75; P = .044) for the composite outcome. CONCLUSIONS AND IMPLICATIONS Measuring frailty provides additive value to widely used pneumonia severity measures in predicting death or persistent hospitalization-associated disability in older adults after pneumonia hospitalization. Early recognition of frailty may be useful to identify those who require in-hospital and post-acute care interventions for functional recovery.

Abstract
The meniscus is a semilunar fibrocartilage structure that plays important roles in maintaining normal knee biomechanics and function. The roles of the meniscus, including load distribution, force transmission, shock absorption, joint stability, lubrication, and proprioception, have been well established. Injury to the meniscus can disrupt overall joint stability and cause various symptoms including pain, swelling, giving-way, and locking. Unless treated properly, it can lead to early degeneration of the knee joint. Because meniscal injuries remain a significant challenge due to its low intrinsic healing potential, most notably in avascular and aneural inner two-thirds of the area, more efficient repair methods are needed. Mesenchymal stem cells (MSCs) have been investigated for their therapeutic potential in vitro and in vivo. Thus far, the application of MSCs, including bone marrow-derived, synovium-derived, and adipose-derived MSCs, has shown promising results in preclinical studies in different animal models. These preclinical studies could be categorized into intra-articular injection and tissue-engineered construct application according to delivery method. Despite promising results in preclinical studies, there is still a lack of clinical evidence. This review describes the basic knowledge, current treatment, and recent studies regarding the application of MSCs in treating meniscal injuries. Future directions for MSC-based approaches to enhance meniscal healing are suggested.

Abstract
AimsRunning is the oldest form of exercise in human history and the most popular exercise in the world.1 While running can improve physical fitness and reduce chronic health problems such as obesity and cardiovascular disease, it is also associated with injuries in lower extremities.2 However, because there was no consensus definition of running-related injury, the prevalence and incidence of running-related injuries had been reported to vary between 19% and 92%.3 Moreover, epidemiology of running-related injuries in Asian populations has been rarely investigated. Therefore, this study was first to use the consensus definition of running-related injuries published in 20153 and investigated the epidemiology of running-related injuries in the Korean population.MethodsIn cross-sectional design, an online survey was circulated among various running communities in Korea. The questionnaire contained information on presence and location of pain attributed to running, demographic characteristics, weekly running mileage, training intensity, running pace, type of shoes, foot strike, reason for running, and exercise experience prior to running.ResultsAmong 1046 runners (male=624, female 422) who responded, 94.7% experienced some kind of pain while running, but only 37% were categorized to have running-related injuries. The most common site of injury was the knee followed by ankle. Exercise experience prior to running (OR 1.57 95% CI 1.13–2.21), setting of specific running goals (OR 1.57 95% CI 1.08–2.27), and mileage increases from 20–30 km to 30–40 km (OR 1.66 95% CI 1.06–2.63) were associated with significant increases in running-related injuries.ConclusionIn order to avoid running-related injuries, runners should be careful in increasing weekly mileage. Moreover, runners with previous exercise experience may need to approach running more cautiously. Setting goals may be motivating but at the same time can increase the risk of running-related injuries.ReferencesVidebæk S, Bueno AM, Nielsen RO, Rasmussen S.

Comparison of muscle strength and neuromuscular control up to 1 year after anterior cruciate ligament reconstruction between patients with dominant leg and non-dominant leg injuries. Knee 2021; 29:15-25. [PMID: 33524658 DOI: 10.1016/j.knee.2021.01.006] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/02/2020] [Revised: 11/18/2020] [Accepted: 01/07/2021] [Indexed: 02/02/2023]
Abstract
BACKGROUND There has not been an investigation to determine whether leg dominance affects the recovery of quadriceps and hamstring strength, muscle reaction time (acceleration time, AT), and postural stability after anterior cruciate ligament (ACL) reconstruction in recreational-level athletic patients. METHODS A total of 100 patients with isolated ACL injuries (58 patients had dominant leg injuries; 42 patients had non-dominant leg injuries) participated. All patients received an anatomical single-bundle ACL reconstruction using an auto-hamstring tendon graft without preoperative rehabilitation. Leg dominance was defined as the kicking leg. The quadriceps and hamstring strength, AT, and postural stability (overall stability index (OSI)) of both legs were assessed at three different time points (preoperative, 6 months, 12 months), using an isokinetic dynamometer and postural stabilometry system. RESULTS All patients in both groups showed gradual improvement in quadriceps and hamstring muscle strength in the operated legs up to 1 year postoperatively. However, the mean value of quadriceps strength was lower in the operated non-dominant leg than the operated dominant leg 6 months postoperatively (P = 0.048). The AT and OSI of the operated legs in both groups recovered significantly 6 months postoperatively compared with their preoperative values; however, the AT and OSI values after 6 and 12 months were similar. CONCLUSION Quadriceps strength of the operated non-dominant leg was lower than that of the operated dominant leg 6 months postoperatively; however, the strength of the quadriceps and hamstring muscles was not different after 12 months between the operated dominant and non-dominant legs. Clinicians and physical therapists should consider these results during early rehabilitation and identify effective protocols to enhance quadriceps strength, especially in patients with non-dominant leg injuries.

Abstract
BACKGROUND Limited data are available on the effect of stretching exercise in patients with patellofemoral pain (PFP) who have inflexible quadriceps, which is one of the various causes of PFP syndrome. This study compares quadriceps flexibility, strength, muscle activation time, and patient-reported outcomes after static and dynamic quadriceps stretching exercises in patients with PFP who had inflexible quadriceps. HYPOTHESIS Quadriceps flexibility and strength, muscle activation time, and patient-reported outcomes would improve with dynamic quadriceps stretching as compared with static quadriceps stretching exercises. STUDY DESIGN Randomized controlled trial. LEVEL OF EVIDENCE Level 2. METHODS Of the 44 patients included in the study, 20 performed static stretching and 24 performed dynamic stretching. Quadriceps flexibility was assessed by measuring the knee flexion angle during knee flexion in the prone position (the Ely test). Muscle strength and muscle activation time were measured using an isokinetic device. The patient-reported outcomes were evaluated using the visual analogue scale for pain and anterior knee pain scale. RESULTS No significant differences in quadriceps flexibility and strength, muscle activation time, and patient-reported outcomes in the involved knees were found between the 2 groups (P values > 0.05). CONCLUSION Quadriceps flexibility and strength, muscle activation time, and patient-reported outcomes in patients with PFP who had inflexible quadriceps showed no significant differences between the static and dynamic quadriceps stretching exercise groups. CLINICAL RELEVANCE Both static and dynamic stretching exercises may be effective for improving pain and function in patients with PFP who have inflexible quadriceps.

Abstract
Objective To investigate the anatomical characteristics of the biceps femoris short head (BS) and determine the optimal needle placement for BS examination. Methods Twenty-one lower limbs were dissected. The distances from the medial and lateral margins of the biceps femoris long head (BL) tendon to the common fibular nerve (CFN) (M_CFN_VD and L_CFN_VD, respectively) and the distance from the lateral margin of the BL tendon to the lateral margin of the BS (L_BS_HD) were measured 5 cm proximal to the tip of the fibular head (P1), four fingerbreadths proximal to the tip of the fibular head (P2), and at the upper apex of the popliteal fossa (P3). Results The BS was located lateral to the BL tendon. The CFN was located along the medial margin of the BL tendon. The median values were 2.0 (P1), 3.0 (P2), and 0 mm (P3) for M_CFN_VD; and 17.4 (P1), 20.2 (P2), and 21.8 mm (P3) for L_CFN_VD; and 8.1 (P1), 8.8 (P2), and 13.0 mm (P3) for L_BS_VD. Conclusion The lateral approach to the BL tendon was safer than the medial approach for examining the BS. Amore proximal insertion site around the upper apex of the popliteal fossa was more accurate than the distal insertion site. In this study, we propose a safer and more accurate approach for electromyography of the BS.

Abstract
BACKGROUND Pneumonia is a major cause of morbidity and mortality in older adults. The role of frailty assessment in older adults with pneumonia is not well defined. Our purpose of the study was to investigate 30-day clinical course and functional outcomes of pneumonia in older adults with different levels of frailty. METHODS A prospective cohort was conducted at a university hospital in Seoul, Korea with 176 patients who were 65 years or older and hospitalized with pneumonia. A 50-item deficit-accumulation frailty index (FI) (range: 0-1; robust < 0.15, pre-frail 0.15-0.24, mild-to-moderately frail 0.25-0.44, and severely frail ≥ 0.45) and the pneumonia severity CURB-65 score (range: 0-5) were measured. Primary outcome was death or functional decline, defined as worsening dependencies in 21 daily activities and physical tasks in 30 days. Secondary outcomes were intensive care unit admission, psychoactive drug use, nasogastric tube feeding, prolonged hospitalization (length of stay > 15 days), and discharge to a long-term care institution. RESULTS The population had a median age 79 (interquartile range, 75-84) years, 68 (38.6 %) female, and 45 (25.5 %) robust, 36 (47.4 %) pre-frail, 37 (21.0 %) mild-to-moderately frail, and 58 (33.0 %) severely frail patients. After adjusting for age, sex, and CURB-65, the risk of primary outcome for increasing frailty categories was 46.7 %, 61.1 %, 83.8 %, and 86.2 %, respectively (p = 0.014). The risk was higher in patients with frailty (FI ≥ 0.25) than without (FI < 0.25) among those with CURB-65 0-2 points (75 % vs. 52 %; p = 0.022) and among those with CURB-65 3-5 points (93 % vs. 65 %; p = 0.007). In addition, patients with greater frailty were more likely to require nasogastric tube feeding (robust vs. severe frailty: 13.9 % vs. 60.3 %) and prolonged hospitalization (18.2 % vs. 50.9 %) and discharge to a long-term care institution (4.4 % vs. 59.3 %) (p < 0.05 for all). Rates of intensive care unit admission and psychoactive drug use were similar. CONCLUSIONS Older adults with frailty experience high rates of death or functional decline in 30 days of pneumonia hospitalization, regardless of the pneumonia severity. These results underscore the importance of frailty assessment in the acute care setting.

Abstract
Background and objectives: Previous studies consistently found no significant difference between supervised and home-based rehabilitation after anterior cruciate ligament reconstruction (ACLR). However, the function of the nonoperative knee, hamstring strength at deep flexion, and neuromuscular control have been overlooked. This prospective observational study was performed to investigate the outcomes after ACLR in operative and nonoperative knees between supervised and home-based rehabilitations. Materials and Methods: After surgery, instructional videos demonstrating the rehabilitation process and exercises were provided for the home-based rehabilitation group. The supervised rehabilitation group visited our sports medicine center and physical therapists followed up all patients during the entire duration of the study. Isokinetic muscle strength and neuromuscular control (acceleration time (AT) and overall stability index (OSI)) of both operative and nonoperative knees, as well as patient-reported knee function (Lysholm score), were measured and compared between the two groups 6 months and 1 year postoperatively. Results: The supervised rehabilitation group showed higher muscle strength of hamstring and quadriceps in nonoperative knees at 6 months (hamstring, p = 0.033; quadriceps, p = 0.045) and higher hamstring strength in operative and nonoperative knees at 1 year (operative knees, p = 0.035; nonoperative knees, p = 0.010) than the home-based rehabilitation group. At 6 months and 1 year, OSIs in operative and nonoperative knees were significantly better in the supervised rehabilitation group than in the home-based rehabilitation group (operative knees, p < 0.001, p < 0.001; nonoperative knees, p < 0.001, p < 0.001, at 6 months and 1 year, respectively). At 1 year, the supervised rehabilitation group also demonstrated faster AT of the hamstrings (operative knees, p = 0.016; nonoperative knees, p = 0.036). Lysholm scores gradually improved in both groups over 1 year; however, the supervised rehabilitation group showed higher scores at 1 year (87.3 ± 5.8 vs. 75.6 ± 15.1, p = 0.016). Conclusions: This study demonstrated that supervised rehabilitation may offer additional benefits in improving muscle strength, neuromuscular control, and patient-reported knee function compared with home-based rehabilitation up to 1 year after ACLR.

Abstract
Even though chronic abdominal pain is 1 of the most common reasons for hospital visits, diagnostic testing is often time-consuming and treatment is inadequate. Abdominal myofascial pain syndrome (AMPS) is usually not included as a differential diagnosis, but it should be considered in cases of chronic abdominal pain. The purpose of this study was to investigate the clinical characteristics of AMPS and to assess the effect of sonography-guided trigger point injections (TPI).A total of 100 patients with AMPS from 2012 to 2018 were retrospectively evaluated for clinical characteristics and TPI effects. AMPS was diagnosed using Srinivasan and Greenbaum's criteria, and the TPIs were performed at intervals of 2 to 4 weeks. The Visual Analog Scale (VAS) ratio was calculated by subtracting the final VAS from the initial VAS score and dividing it by the initial VAS score after injections, and the patients were divided into 4 groups: non-responders, mild, moderate, and good responders.The median duration of pain was 12 months, and the median number of hospital visits before TPI was 2. Of the 100 patients, 66 (66%) were categorized as good responders, 11 (11%) as moderate responders, 7 (6.9%) as mild responders, and 16 (15.7%) as non-responders. When the initial and final VAS scores were compared, the sonography-guided injections were found to be effective in alleviating pain (P < .001). Moreover, patients who received the injections 2 or more times tended to have more significant pain reduction than those who received a single injection (P < .001).Patients with AMPS suffer from long-term pain and undergo many hospital visits and diagnostic tests. TPI with lidocaine can be an effective and safe treatment for patients with chronic AMPS.

Effect of citrulline on post-exercise rating of perceived exertion, muscle soreness, and blood lactate levels: A systematic review and meta-analysis. JOURNAL OF SPORT AND HEALTH SCIENCE 2020; 9:553-561. [PMID: 33308806 PMCID: PMC7749242 DOI: 10.1016/j.jshs.2020.02.003] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/11/2019] [Revised: 08/04/2019] [Accepted: 12/30/2019] [Indexed: 05/25/2023]
Abstract
BACKGROUND Citrulline is one of the non-essential amino acids that is thought to improve exercise performance and reduce post-exercise muscle soreness. We conducted a systematic review and meta-analysis to determine the effect of citrulline supplements on the post-exercise rating of perceived exertion (RPE), muscle soreness, and blood lactate levels. METHODS A random effects model was used to calculate the effect sizes due to the high variability in the study design and study populations of the articles included. A systematic search of PubMed, Web of Science, and ClinicalTrials.gov was performed. Eligibility for study inclusion was limited to studies that were randomized controlled trials involving healthy individuals and that investigated the acute effect of citrulline supplements on RPE, muscle soreness, and blood lactate levels. The supplementation time frame was limited to 2 h before exercise. The types and number of participants, types of exercise tests performed, supplementation protocols for L-citrulline or citrulline malate, and primary (RPE and muscle soreness) and secondary (blood lactate level) study outcomes were extracted from the identified studies. RESULTS The analysis included 13 eligible articles including a total of 206 participants. The most frequent dosage used in the studies was 8 g of citrulline malate. Citrulline supplementation significantly reduced RPE (n = 7, p = 0.03) and muscle soreness 24-h and 48-h after post-exercise (n = 7, p = 0.04; n = 6, p = 0.25, respectively). However, citrulline supplementation did not significantly reduce muscle soreness 72-h post-exercise (n = 4, p = 0.62) or lower blood lactate levels (n = 8, p = 0.17). CONCLUSION Citrulline supplements significantly reduced post-exercise RPE and muscle soreness without affecting blood lactate levels.

Abstract
BACKGROUND To date, much of the rehabilitation following anterior cruciate ligament reconstruction (ACLR) has centered on physical components. However, clinical outcomes including return to sport after ACLR depends on not only physical recovery but also psychological components. This study was performed to assess the feasibility of 6-month modeling video intervention on psychological responses following ACLR. METHODS Following the baseline assessment of psychological measures through Knee Self Efficacy Scale (K-SES), ACL-Return to Sport after Injury (ACL-RSI), and Tampa Scale of Kinesiophobia-11 (TSK-11), 32 patients scheduled for ACLR were randomly assigned to intervention (n = 10), placebo (n = 11), or control (n = 11) group. Six modeling videos and placebo videos were developed by the investigators. Intervention and placebo groups watched their respective videos during their follow-up visits while control group did not. All groups completed psychological assessments during hospitalization, at 2 weeks, at 6 weeks, at 3 months, and at 6 months following ACLR. Also, Knee Injury and Osteoarthritis Outcome Score (KOOS) was used to evaluate symptoms and function of the knee at 3 and 6 months after surgery. RESULTS No significant changes in K-SES, ACL-RSI, and TSK-11 scores over 6-month period were observed among groups (P = .808, P = .574, P = .888, respectively). Compared with baseline, only the scores of K-SES improved with statistical significance in the intervention, placebo, and control groups (P = .05, .01, .00) at 6 months after ACLR. The KOOS subscale scores were not significantly different among the intervention, placebo, and control groups at 3 and 6 months. CONCLUSION A modeling video intervention, although feasible, was not effective in addressing the psychological risk factors in patients undergoing ACLR.

Abstract
A limited number of studies has investigated the gastrocnemius and soleus in patients undergoing anterior cruciate ligament reconstruction (ACLR). This study investigated the muscle strength (Nm kg−1 × 100) and reaction time (acceleration time (AT), milliseconds) of thigh and calf muscles in patients undergoing ACLR. Thirty-two patients with ACLR and 32 normal control subjects were included. One year postoperatively, the strength of thigh muscles was significantly reduced after ACLR compared with that of controls (hamstring: 80 ± 31.3 vs. 142 ± 26.4, p < 0.001, quadriceps: 159 ± 63.7 vs. 238 ± 35.3, p < 0.001). However, the strength of calf muscles was not significantly different compared with that of controls (gastrocnemius: 77 ± 22.9 vs. 81 ± 22.5, p = 0.425, soleus: 54 ± 15.9 vs. 47 ± 16.1, p = 0.109). The AT of calf muscles was significantly faster after ACLR than that of controls (gastrocnemius: 26 ± 9.8 vs. 31 ± 9, p = 0.030, soleus: 18 ± 6.7 vs. 22 ± 8.5, p = 0.026). The AT of thigh muscles was significantly elongated after ACLR than that of controls (hamstring: 72 ± 18 vs. 55 ± 12.4, p < 0.001, quadriceps: 63 ± 17.6 vs. 47 ± 17, p < 0.000). The strength of thigh muscles was reduced, and the ATs of thigh muscles were slower one year after ACLR. However, the AT of the triceps surae was faster than that of controls. This may implicate a compensatory mechanism of the triceps surae for the weakness and delayed activation in hamstring and quadriceps muscles.

Teaching online: foundational concepts of online learning and practical guidelines. KOREAN JOURNAL OF MEDICAL EDUCATION 2020; 32:175-183. [PMID: 32894921 PMCID: PMC7481046 DOI: 10.3946/kjme.2020.171] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 07/15/2020] [Accepted: 07/23/2020] [Indexed: 05/23/2023]
Abstract
Medical schools have been slowly adopting online learning into pedagogical methods for more than a decade. While some medical educators are reluctant to accept these changes, the ongoing coronavirus disease 2019 (COVID-19) pandemic poses a threat to the delivery of traditional medical education, which has accelerated the inevitable implementation of online learning. This sudden change may be a new challenge to medical educators who are new to this territory. Therefore, this review aims to provide foundational concepts of online learning and practical guidelines in the context of medical education. The authors first identify three foundational concepts, which are transactional distance, presence, and independent learners. In online learning, transactional distance, determined by dialogue and structure, becomes more important than physical distance. Furthermore, effective and successful online learning requires the achievement and accommodation of cognitive, social, and teaching presences. It is also crucial to recognize learners not as passive recipients of information predefined by a teacher, but as active, capable, and independent individuals. The authors, then, discuss the practical guidelines for designing an effective online curriculum. Five online pedagogical guidelines are laid out in this review: design structures and flows to embrace experiential learning, accommodate both synchronous and asynchronous learning, design/facilitate interactions, promote practice opportunities, and promote a learning community. By understanding the foundational concepts and applying these guidelines, the adoption of online learning in the medical school may supplement the traditional medical education or even provide additional benefits in the new normal after the COVID-19 pandemic.

Abstract
PURPOSE Clinical rotations of medical students across the world have inevitably been affected due to the coronavirus disease 2019 (COVID-19) pandemic. The aims of this study were to explore medical students' perception on the school's response and management of clinical rotation during the COVID-19 pandemic and on how it had affected the quality of their education. METHODS An online questionnaire was distributed to third year medical students at one institution whose clinical rotations re-started during the pandemic. The questions asked about the students' satisfaction with the school's policy and feelings of safety, and the impact of COVID-19 on clinical learning. RESULTS The students' perception on the school's response to the pandemic was mixed. Re-commencement of the clinical rotations and procurement of personal protective equipment was positive but a third of students still felt unsafe. The decreased number of hospital patients did not seem to have impacted their overall clinical education with praise on the role of the supervising physicians. Seventy-six-point seven percent of students conferred the positive educational opportunities on medical professionalism presented to them only as the clinical rotation during the ongoing pandemic. CONCLUSION Our observations on the re-commencement of clerkship during this pandemic may help equip medical institutions on future public health crisis.

Abstract
BACKGROUND Patellofemoral pain (PFP) syndrome is closely associated with muscle tightness. However, studies regarding the effects of stretching exercises on PFP patients with inflexible hamstrings are scarce. The aim of the study was to compare the effects between static and dynamic hamstring stretching in patients with PFP who have inflexible hamstrings. HYPOTHESIS Compared with static hamstring stretching, dynamic hamstring stretching will improve the parameters of hamstring flexibility, knee muscle strength, muscle activation time, and clinical outcomes in this patient population. STUDY DESIGN Prospective randomized controlled trial. LEVEL OF EVIDENCE Level 2. METHODS A total of 46 patients (25, static stretching; 21, dynamic stretching) participated. Hamstring flexibility was assessed according to the popliteal angle during active knee extension. Muscle strength and muscle activation time were measured using an isokinetic device. Clinical outcomes were evaluated using the visual analog scale (VAS) for pain and the anterior knee pain scale (AKPS). RESULTS There were no differences in hamstring flexibility and knee muscle strength of the affected knees between the groups (P > 0.05). Significantly improved muscle activation time and clinical outcomes of the affected knees were observed in the dynamic stretching group compared with the static stretching group (all Ps < 0.01 for hamstring, quadriceps, VAS, and AKPS). CONCLUSION In patients with PFP who have inflexible hamstrings, dynamic hamstring stretching with strengthening exercises was superior for improving muscle activation time and clinical outcomes compared with static hamstring stretching with strengthening exercises. CLINICAL RELEVANCE Clinicians and therapists could implement dynamic hamstring stretching to improve function and reduce pain in patients with PFP who have inflexible hamstrings.

Comparative Efficacy and Tolerability of Nonsurgical Therapies for the Treatment of Midportion Achilles Tendinopathy: A Systematic Review With Network Meta-analysis. Orthop J Sports Med 2020; 8:2325967120930567. [PMID: 32728589 PMCID: PMC7366412 DOI: 10.1177/2325967120930567] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Accepted: 03/10/2020] [Indexed: 12/14/2022] Open
Abstract
Background: Achilles tendinopathy (AT) is a common cause of overuse injury in both
athletes and nonactive individuals, especially at older ages. Due to the
limited number of direct comparisons among interventions, determining the
best treatment option can be difficult. Purpose: To evaluate the comparative efficacy and tolerability of nonsurgical
therapies for midportion AT. Study Design: Systematic review; Level of evidence, 1. Methods: PubMed, MEDLINE, EMBASE, and Google Scholar were searched from database
inception through June 20, 2019. Randomized controlled trials investigating
the effect of nonsurgical therapies for midportion AT using the Victorian
Institute of Sports Assessment–Achilles (VISA-A) assessment were eligible
for inclusion. Primary outcome was mean change in VISA-A score from
baseline. Comparisons between interventions were made through use of
random-effects network meta-analysis over the short term (≤3 months) and
longer term (>3 to <12 months). A safety profile was defined for each
intervention by rate of all-cause discontinuation (dropout) during
follow-up. Relative ranking of therapies was assessed by the
surface-under-the–cumulative ranking possibilities. Results: A total of 22 studies with 978 patients met the inclusion criteria. In
short-term studies, high-volume injection with corticosteroid (HVI+C) along
with eccentric exercise (ECC) significantly improved the change of VISA-A
score compared with that of ECC alone (standardized mean difference [SMD],
1.08; 95% CI, 0.58-1.58). Compared with ECC, acupuncture showed benefits
over both the short term (SMD, 1.57; 95% CI, 1.00-2.13) and longer term
(SMD, 1.23; 95% CI, 0.69-1.76). In longer-term studies, the wait-and-see
approach resulted in unfavorable outcomes compared with ECC (SMD, −1.51; 95%
CI, −2.02 to −1.01). Improvement was higher when ECC was combined with HVI+C
(SMD, 0.53; 95% CI, 0.05-1.02) and extracorporeal shockwave therapy (ESWT)
(SMD, 0.99; 95% CI, 0.48-1.49). All interventions had a similar safety
profile. Conclusion: From available high-level studies, HVI+C and ESWT may be possible
interventions to add along with ECC to improve longer-term outcomes.

Abstract
We performed a network meta-analysis to build clear hierarchies of efficacy and tolerability of pharmacological interventions for the treatment and prevention of delirium. Electronic databases including PubMed, Google Scholar, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, and MEDLINE were searched published up to February 22, 2019. A total of 108 randomized controlled trials (RCTs) investigating pharmacotherapy on delirium were included for analysis, and the strength of evidence (SoE) was evaluated for critical outcomes. In terms of treatment, quetiapine (low SoE), morphine (low SoE), and dexmedetomidine (moderate SoE) were effective in the intensive care unit (ICU) patients. In terms of prevention, dexmedetomidine (high SoE) and risperidone (high SoE) significantly reduced the incidence of delirium in ICU surgical patients, while ramelteon (high SoE) reduced the incidence of delirium in ICU medical patients. Despite the efficacy, dexmedetomidine and risperidone demonstrated higher drop-out rate (moderate to high SoE). Haloperidol and other antipsychotics, except for quetiapine and risperidone, showed no benefit. None of the agents showed benefit in non-ICU patients. In conclusion, dexmedetomidine may be a drug of choice for both treating and preventing delirium of the ICU and postsurgical patients. However, it may be less tolerable, and side-effects should be adequately managed. Current evidence does not support the routine use of antipsychotics. For medical patients, oral ramelteon might be useful for prevention.

Abstract
Renal hemangioma is an uncommon benign tumor which usually causes painless or painful gross hematuria. Its preoperative diagnosis is extremely difficult or even impossible. We experienced three cases of renal hemangioma, located mainly at the pelvocalyceal junction or in the inner medulla. US demonstrated variable echogenecity, and CT revealed a lack of significant enhancement. Where there is gross hematuria in a young adult, especially when the renal mass located in the pelvocalyceal junction or inner medulla shows little enhancement on CT, renal hemangioma should form part of the differential diagnosis.

Abstract
PURPOSE The purpose of this study was to determine the CT and MR characteristics of Brenner tumors, rare epithelial neoplasms of the ovary. METHOD CT and MR scans of eight pathologically proven Brenner tumors of the ovary (seven benign, one malignant, and one associated with mucinous cystadenoma) were retrospectively reviewed. The masses were analyzed for location, size, external configuration, internal architecture, enhancement pattern, presence of calcification, and metastatic spread. RESULTS The patients' median age was 63 years (range 39-79 years), and the mean size of the tumors was 11.4 cm (7.5-17 cm). All tumors were unilateral and had a well-defined margin. The mass was mostly solid in three, mostly cystic in one, and "mixed" solid and cystic in four cases. The tumors with cystic components (n = 5) were mostly multilocular in appearance (n = 4). All the solid components showed mild homogeneous enhancement on postcontrast CT and MRI. Extensive amorphous calcification within the solid component on CT was seen in five of six cases (83%). No characteristic findings discriminating malignancy from benign Brenner tumor could be found. CONCLUSION Extensive amorphous calcification in a solid mass or solid component in a multilocular cystic mass is a characteristic finding of Brenner tumor of the ovary on CT and MRI.

Abstract
PURPOSE The purpose of this work was to evaluate the usefulness of CT scans for distinguishing torsed from uncomplicated benign cystic teratoma (BCT). METHOD Retrospective analysis was performed in 14 torsed BCTs (14 patients) and in 23 uncomplicated BCTs (20 patients) for comparison. The features on CT scans were compared to the pathologic findings. RESULTS CT findings indicating torsed BCT were the presence of eccentric wall thickening of >1 cm, peritumoral infiltration, and presence of enlarged solid tubal mass adjacent to the uterus (p < 0.05). CONCLUSION The present study suggests that CT is useful in differentiating torsed from uncomplicated BCT. Although CT findings are not specific for some patients, detection of certain CT findings could increase the diagnostic accuracy.

Abstract
Primary malignant lymphoma of the uterus is a rare disease. We present the MR findings in three cases where the uterus was the initial site. MR findings wer retrospectively evaluated. Although the intact junctional zone is a specific finding for lymphoma, diffuse enlargement of the uterus and relatively homogeneous signal intensity on MR imaging in spite of large tumor size are helpful for diagnosing uterine lymphoma.
