Web Site Accessibility Among Doctor of Physical Therapy Programs in the United States.

INTRODUCTION: Given the impetus to improve accessibility for diverse learners seeking physical therapist education, it is critical that all entry points to access information have minimal barriers. This study identified Web site accessibility barriers among Doctor of Physical Therapy (DPT) programs in the United States. REVIEW OF LITERATURE: Web site accessibility has been evaluated among many institutions of higher education, but none focused on DPT education. Individuals with disabilities may be adversely affected by Web site accessibility barriers. SUBJECTS: This cross-sectional study included 262 DPT programs in the United States. Doctor of Physical Therapy program characteristics collected were geographic region, institutional control type (public/private), medical school affiliation, accreditation status, total institutional enrollment, and DPT class size. METHODS: The Web Accessibility Evaluation (WAVE) Tool assessed data related to accessibility barriers among DPT program homepage Uniform Resource Locators. Three primary outcomes from the WAVE Tool included WAVE Total Errors, Error Density, and Total Alerts. RESULTS: Web site homepage accessibility barriers varied among programs for WAVE Total Errors (range 0-150), Error Density (range 0-14.6%), and Total Alerts (range 1-331). Median Total Errors were greater among private (9.0) versus public (5.0) institution Web sites (P < .001). Median Total Errors were greater among those institutions not affiliated with a medical school (9.0) compared with those that had an affiliated medical school (7.0) (P = .04). No differences in accessibility barriers were identified according to geographic region or accreditation status (P > .05). Median Total Errors were significantly different between institutional enrollment quartiles (H[3] = 17.9, P < .001), with no differences noted between DPT class size quartiles for any outcome (P > .05). Generally, weak-fair inverse correlations were observed between student enrollment for the institution and Web site accessibility barrier outcomes. DISCUSSION AND CONCLUSION: Homepage accessibility barriers varied greatly among DPT programs in the United States. Factors, including being a private institution, no medical school affiliation, and lower institutional enrollment, were related to increased accessibility barriers.

The Comparative Mental Health Responses Between Post-Musculoskeletal Injury and Post-Concussive Injury Among Collegiate Athletes: A Systematic Review.

BACKGROUND: The average annual national estimate of injuries sustained by collegiate athletes is 210,674, which encompasses both those of a musculoskeletal and a concussive nature. Although athletic injuries are sustained through physical means and produce physical symptoms, sports-related injuries may be a stressor among athletes that is related to mental health. PURPOSE: The purpose of this systematic review is to summarize existing literature describing mental health responses in collegiate athletes with a concussion compared to those with a musculoskeletal injury. STUDY DESIGN: Systematic Review. METHODS: Systematic searches of PubMed, CINAHL, Scopus, ProQuest, and SportDiscus were completed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized. Methodological quality was assessed using the Joanna Briggs Institute (JBI) Critical Appraisal Tool. Data extracted from the included articles included the study design, number of participants, type of injury, sex, age, sport participation, outcome measures, and time to return to play. RESULTS: A total of six articles were included. Peak depressive symptoms in athletes who sustain a concussion or musculoskeletal injury occur within one-week post-injury. No significant differences between the concussive and musculoskeletal groups anxiety scores were found at baseline or at each follow-up session. Athletes from both groups were found to be returning to their respective sports with anxiety scores representative of clinical anxiety. CONCLUSION: Similar trends in depressive and anxiety symptoms at various time points post-injury were observed in athletes with both musculoskeletal and concussive injuries. This study identified that athletes were returning to play before their psychological symptoms had returned to their baseline. LEVEL OF EVIDENCE: 2a.

The Effects of Exercise Dosage on Neck-Related Pain and Disability: A Systematic Review With Meta-analysis.

OBJECTIVE: To (1) evaluate whether exercise therapy is effective for managing neck pain, and (2) investigate the relationship between exercise therapy dosage and treatment effect. DESIGN: Intervention systematic review with meta-analysis and meta-regression. LITERATURE SEARCH: An electronic search of 6 databases was completed for trials assessing the effects of exercise therapy on neck pain. STUDY SELECTION CRITERIA: We included randomized controlled trials that compared exercise therapy to a no-exercise therapy control for treating neck pain. Two reviewers screened and selected studies, extracted outcomes, assessed article risk of bias, and rated the quality of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. DATA SYNTHESIS: Data were pooled using random-effects meta-analysis. We used meta-regression to analyze the effect of exercise dosage on neck pain and disability. RESULTS: Fourteen trials were included in the review. Seven trials were at high risk of bias, 4 were at unclear risk of bias, and 3 were at low risk of bias. Exercise therapy was superior to control for reducing pain (visual analog scale mean difference, -15.32 mm) and improving disability (Neck Disability Index mean difference, -3.64 points). Exercise dosage parameters did not predict pain or disability outcomes. CONCLUSION: Exercise was beneficial for reducing pain and disability, regardless of exercise therapy dosage. Therefore, optimal exercise dosage recommendations remain unknown. We encourage clinicians to use exercise when managing mechanical neck pain.

The relationship between measures of foot mobility and subtalar joint stiffness using vibration energy with color Doppler imaging-A clinical proof-of-concept validation study.

INTRODUCTION: Subtalar joint (STJ) dysfunction can contribute to movement disturbances. Vibration energy with color Doppler imaging (VECDI) may be useful for detecting STJ stiffness changes. OBJECTIVES: (1) Support proof-of-concept that VECDI could detect STJ stiffness differences; (2) Establish STJ stiffness range in asymptomatic volunteers; (3) Examine relationships between STJ stiffness and foot mobility; and (4) Assess VECDI precision and reliability for examining STJ stiffness. METHODS: After establishing cadaveric testing model proof-of-concept, STJ stiffness (threshold units, ΔTU), ankle complex passive range-of-motion (PROM) and midfoot-width-difference (MFWDiff) data were collected in 28 asymptomatic subjects in vivo. Three reliability measurements were collected per variable; Rater-1 collected on all subjects and rater-2 on the first ten subjects. Subjects were classified into three STJ stiffness groups. RESULTS: Cadaveric VECDI measurement intra-rater reliability was 0.80. A significantly lower STJ ΔTU (p = .002) and ankle complex PROM (p < .001) was observed during the screw fixation versus normal condition. A fair correlation (r = 0.660) was observed between cadaveric ΔTU and ankle complex PROM. In vivo VECDI measurements demonstrated good intra-rater (0.76-0.84) versus poor inter-rater (-3.11) reliability. Significant positive correlations were found between STJ stiffness and both dorsum (r = .440) and posterior (r = .390) PROM. MFWDiff exhibited poor relationships with stiffness (r = .103) and either dorsum (r = .256) or posterior (r = .301) PROM. STJ stiffness ranged from 2.33 to 7.50 ΔTUs, categorizing subjects' STJ stiffness as increased (n = 6), normal (n = 15), or decreased (n = 7). Significant ANOVA main effects for classification were found based on ΔTU (p< .001), dorsum PROM (p = .017), and posterior PROM (p = .036). Post-hoc tests revealed significant: (1) ΔTU differences between all stiffness groups (p < .001); (2) dorsum PROM differences between the increased versus normal (p = .044) and decreased (p = .017) stiffness groups; and (3) posterior PROM differences between the increased versus decreased stiffness groups (p = .044). A good relationship was found between STJ stiffness and dorsum PROM in the increased stiffness group (r = .853) versus poor, nonsignificant relationships in the normal (r = -.042) or decreased stiffness (r = -.014) groups. CONCLUSION: PROM may not clinically explain all aspects of joint mobility. Joint VECDI stiffness assessment should be considered as a complimentary measurement technique.

THE TENSILE BEHAVIORS OF THE ILIOTIBIAL BAND - A CADAVERIC INVESTIGATION.

BACKGROUND: Clinical stretching is frequently recommended for iliotibial band syndrome management. Current literature lacks conclusive findings regarding isolated human iliotibial band tissue elongation and stiffness behaviors. Applying clinical-grade stretching force results to iliotibial band tissue behavior is thus challenging. PURPOSE: This study's objectives were to determine isolated iliotibial band tissue tensile behaviors during tension-to-failure testing and to relate the results to previously reported iliotibial band stretch findings. STUDY DESIGN: Descriptive in vitro laboratory study. METHODS: Ten isolated un-embalmed iliotibial band specimens were exposed to tension-to-failure testing using a 10kN material testing system. Peak load, load at yield point, and ultimate failure load were measured in Newtons. Corresponding absolute (mm) and relative (%) tissue deformation was recorded. Load-deformation curves were established to calculate iliotibial band stiffness (N/mm). RESULTS: A mean peak load of 872.8 ± 285.9N and resulting 9.0 ± 3.9% tissue deformation from initial length was recorded. An 805.5 ± 249.7N mean load at yield point and resulting 7.0 ± 1.9% tissue deformation was observed. A 727.6 ± 258.4N mean load was recorded directly prior to ultimate tissue failure. Mean tissue deformation at ultimate failure was 11.3 ± 4.2%. Mean iliotibial band system stiffness was 27.2 ± 4.5N/mm. CONCLUSION: The iliotibial band can withstand substantial tensile forces. Clinical stretching forces likely fall within the load-deformation curve elastic region and may not result in permanent iliotibial band tissue deformation. Sustained elongation resulting from stretching the ITB may require substantial patient compliance. Future studies should investigate potential underlying factors related to positive symptom relief from iliotibial band stretching that include immunological responses, fluid accumulation, altered proprioception, and pain perception.

A Fatal Case of Disseminated Microsporidiosis Due to Anncaliia algerae in a Renal and Pancreas Allograft Recipient.

Microsporidiosis is an emerging opportunistic infection in immunocompromised patients. We report a case of fatal disseminated Anncaliia algerae infection in a profoundly immunosuppressed pancreas and kidney transplant recipient.

Anatomical relationship of palmar carpal bone landmarks used in locating the lunate and capitate during palpation: A cadaveric investigation.

STUDY DESIGN: Descriptive in situ cadaveric study. INTRODUCTION: Performing accurately directed examination and treatment to the wrist requires clinicians to orient to carpal bone structures. PURPOSE OF THE STUDY: To examine the anatomical relationships that exist within the wrist-hand complex and identify the accuracy of surface anatomy mapping strategies for localizing anatomical landmarks using a palmar approach. METHODS: Twenty-three embalmed cadavers were dissected using standardized procedures. Metal markers were placed in the most prominent palmar landmark of key carpal structures. Relationships between the most prominent palpation landmarks and the carpal bones of interest were visualized using fluoroscopy. RESULTS: The most successful methods of palmar capitate localization included the midpoint of a line from trapezium tubercle to pisiform; the midpoint of a line from scaphoid tubercle to hamate hook; or the intersection (cross) of these 2 diagonal lines, with successful capitate identification 100% (23/23) of the time. The most successful method for locating the lunate included the midpoint of a line from the radial styloid process to the ulnar styloid process, which identified the lunate in 100% (23/23) of cases. DISCUSSION: The results of this cadaveric anatomical relationship study support the use of the midpoint of a line from pisiform to trapezium tubercle, the midpoint of a line from scaphoid tubercle to hamate hook, or a combination (cross) of these lines to locate the capitate from a palmar approach. In addition, the anatomical relationships examined in this study support the use of the midpoint of a line from the radial styloid process to ulnar styloid process to locate the lunate from a palmar approach. Knowledge of these anatomical relationships may improve the clinician's confidence in locating the capitate and lunate during intercarpal examination, special testing, and treatment. CONCLUSION: Results of this study provide information of the anatomical relationships of the carpal bones from a palmar approach, giving clinicians a foundation for proper orientation to the carpal bones during clinical examination and intervention. Further research is needed to evaluate the reliability and accuracy of these methods for surface palpation on live patients.

Left Ventricular Assist Device Infections: A Systematic Review.

Left ventricular assist devices (LVADs) are becoming a more frequent life-support intervention. Gaining an understanding of risk factors for infection and management strategies is important for treating these patients. We conducted a systematic review and meta-analysis of studies describing infections in continuous-flow LVADs. We evaluated incidence, risk factors, associated microorganisms, and outcomes by type of device and patient characteristics. Our search identified 90 distinct studies that reported LVAD infections and outcomes. Younger age and higher body mass index were associated with higher rates of LVAD infections. Driveline infections were the most common infection reported and the easiest to treat with fewest long-term consequences. Bloodstream infections were not reported as often, but they were associated with stroke and mortality. Treatment strategies varied and did not show a consistent best approach. LVAD infections are a significant cause of morbidity and mortality in LVAD patients. Most research comes from secondary analyses of other LVAD studies. The lack of infection-oriented research leaves several areas understudied. In particular, bloodstream infections in this population merit further research. Providers need more research studies to make evidence-based decisions about the prevention and treatment of LVAD infections.

Epidemiology, risk factors, and outcomes of infections in patients undergoing liver transplantation for hilar cholangiocarcinoma.

The epidemiology of infection after liver transplantation for hilar cholangiocarcinoma has not been systematically investigated. In this study of 124 patients, 255 infections occurred in 105 patients during the median follow-up of 4.2 years. The median time to first infection was 15.1 weeks (IQR 1.6-62.6). The most common sites were the abdomen, bloodstream, and musculoskeletal system. Risk factors for any post-transplant infection were pre-transplant VRE colonization (Hazard Ratio [HR] 1.9, P=.002), living donor transplantation (HR 6.6, P<.001), longer cold ischemia time (HR 1.05 per 10 minutes, P<.001), donor CMV seropositivity (HR 2.2, P<.001), hepatic artery thrombosis (HR 2.6, P=.005), biliary stricture (HR 3.8, P=.002), intra-abdominal fluid collection (HR 4.2, P<.001), and re-operations within 1 month after transplantation (HR 1.7, P=.020). Abdominal infections were independently associated with hemodialysis requirement within 1 month after transplantation (HR 5.6, P=.006), hepatic artery thrombosis (HR 3.3, P=.007), biliary stricture (HR 5.2, P<.001), and abdominal fluid collection (HR 3.7, P=.0002). Bloodstream infections were independently associated with allograft ischemia (HR 17.8, P<.001), biliary stricture (HR 6.5, P=.005), and recipient VRE colonization (HR 4, P<.001). Abdominal infections (HR 2.3, P=.02) and Clostridium difficile infections (HR 4.6, P=.01) were independently associated with increased mortality.

The Effect of Distractive Function on Volitional Preemptive Abdominal Contraction During a Loaded Forward Reach in Normal Subjects.

BACKGROUND: Volitional preemptive abdominal contraction (VPAC) is used to protect the spine and prevent injury. No published studies to data have examined the effect of distraction on VPAC use during function. OBJECTIVE: To examine the effect of an auditory distraction ("Stroop task") on healthy subjects' ability to sustain VPAC by use of the abdominal drawing-in maneuver during loaded forward reach. DESIGN: Within-subjects, repeated-measure cohort design. SETTING: Clinical laboratory setting. PARTICIPANTS: Convenience sample of 42 healthy individuals (ages 20-57 years). METHODS: Transversus abdominis (TrA) thickness was measured with M-mode ultrasound imaging. Each subject performed Stroop versus no Stroop during 4 conditions: (1) without VPAC, quiet standing; (2) with VPAC, quiet standing; (3) without VPAC, forward reach; and (4) with VPAC, forward reach. An investigator blinded to the conditions measured the first 10 subjects to establish intratester reliability of probe/transducer placement and TrA measurement. DATA REDUCTION: TrA thickness (mm) change represented VPAC performance. A single investigator measured onscreen TrA thickness twice at each second from second-6 through -10 on a recorded ultrasound imaging sequence. RESULTS: A 2 (Stroop) × 4 (Activity) repeated-measures analysis of variance found no significant Stroop × Activity interaction [F(3, 93) = 0.345, P = .793] and no main effect for Stroop [F (1,31) = 1.324, P = .259] but found a significant main effect for activity [F (3,93) = 17.729, P < .001]. Tukey post-hoc pairwise comparisons demonstrated significant differences between VPAC versus no-VPAC conditions, except between quiet standing/yes-VPAC and loaded forward reach/no-VPAC conditions (P = .051). The interclass correlation coefficient (3,2) for probe/transducer placement reliability was 0.87, 0.91, 0.92, and 0.93 for conditions 1-4, respectively. The interclass correlation coefficient (3,2) for TrA measurement reliability was 0.96, 0.99, 0.99, and 0.99 for conditions 1-4, respectively. CONCLUSION: A distracting executive function (Stroop task) did not produce a significant negative impact on normal individuals' ability to sustain a VPAC during quiet standing or loaded forward reach activities. LEVEL OF EVIDENCE: II.

Misidentification of Neosartorya pseudofischeri as Aspergillus fumigatus in a lung transplant patient.

We present a case of disseminated Neosartorya pseudofischeri infection in a bilateral lung transplant patient with cystic fibrosis. The organism was originally misidentified from respiratory specimens as Aspergillus fumigatus using colonial and microscopic morphology. DNA sequencing subsequently identified the organism correctly as N. pseudofischeri.

Current concepts in the diagnosis and management of left ventricular assist device infections.

Left ventricular assist devices (LVAD) are increasingly being used both as a bridge to transplantation and for long-term myocardial surrogate destination therapy in patients with end-stage heart failure. Primarily owing to the presence of a driveline that connects the device to an external battery through an open skin incision, the rates of LVAD-related infections (LVADRIs) are high, ranging from 30 to 50%. LVADRIs can be broadly classified into driveline infection, pump pocket infection, bloodstream infection and endocarditis/pump or cannula infection. Diagnostic evaluation and management of these complicated infections can be quite challenging for clinicians involved in the care of these patients. Here, the authors summarize the current epidemiology, microbiology, diagnostic approach and management strategies for each type of LVADRI. The authors also review current concepts regarding antibiotic prophylaxis for LVAD implantation. Finally, the authors highlight the gaps in the knowledge of LVADRI and provide directions for future studies.

Helicobacter canis bacteremia in a patient with fever of unknown origin.

A 57-year-old woman with common variable immune deficiency and liver failure of unknown etiology presented with recurrent fevers over a 5-month period. She was found to have Helicobacter canis bacteremia. Immunocompromised hosts with exposure to cats or dogs may be at risk for infection with this organism, which may be challenging to diagnose.

Mycobacterium wolinskyi: a case series and review of the literature.

Mycobacterium wolinskyi is an uncommonly encountered rapidly growing mycobacterium. To date, only 12 clinical cases have been reported in the literature. In this report, we describe 5 additional cases of M. wolinskyi infection seen at the Mayo Clinic in Rochester, MN, since 2009. The clinical manifestations were sternal wound infections (n = 2), a surgical site wound infection, a cardiac-device pocket site infection, and a vascular graft infection with bacteremia. The infections occurred in both immunocompetent and immunosuppressed patients, including a lung transplant recipient. Treatment of M. wolinskyi infections required a prolonged course of combination antimicrobial treatment and surgical debridement.

Emergence of a new pathogenic Ehrlichia species, Wisconsin and Minnesota, 2009.

BACKGROUND: Ehrlichiosis is a clinically important, emerging zoonosis. Only Ehrlichia chaffeensis and E. ewingii have been thought to cause ehrlichiosis in humans in the United States. Patients with suspected ehrlichiosis routinely undergo testing to ensure proper diagnosis and to ascertain the cause. METHODS: We used molecular methods, culturing, and serologic testing to diagnose and ascertain the cause of cases of ehrlichiosis. RESULTS: On testing, four cases of ehrlichiosis in Minnesota or Wisconsin were found not to be from E. chaffeensis or E. ewingii and instead to be caused by a newly discovered ehrlichia species. All patients had fever, malaise, headache, and lymphopenia; three had thrombocytopenia; and two had elevated liver-enzyme levels. All recovered after receiving doxycycline treatment. At least 17 of 697 Ixodes scapularis ticks collected in Minnesota or Wisconsin were positive for the same ehrlichia species on polymerase-chain-reaction testing. Genetic analyses revealed that this new ehrlichia species is closely related to E. muris. CONCLUSIONS: We report a new ehrlichia species in Minnesota and Wisconsin and provide supportive clinical, epidemiologic, culture, DNA-sequence, and vector data. Physicians need to be aware of this newly discovered close relative of E. muris to ensure appropriate testing, treatment, and regional surveillance.

Emergence of drug-resistant cytomegalovirus in the era of valganciclovir prophylaxis: therapeutic implications and outcomes.

BACKGROUND: Valganciclovir prophylaxis is reportedly associated with a low incidence of ganciclovir-resistant cytomegalovirus (CMV). We assessed the incidence, clinical features, and outcome of drug-resistant CMV among solid organ transplant patients who received valganciclovir prophylaxis. METHODS: The medical records of all CMV D+/R- kidney, pancreas, liver, and heart recipients were screened for CMV disease, and the clinical course and outcomes of patients with drug-resistant CMV were reviewed. RESULTS: During a four-yr-study period, a total of 225 CMV D+/R- transplant patients received valganciclovir prophylaxis for a median of 92 d. Sixty-five (29%) of the 225 patients developed delayed-onset primary CMV disease, including nine (14%) suspected to have drug-resistant virus. Four (6.2%) had confirmed UL97 or UL54 mutations. All except one patient manifested gastrointestinal tissue-invasive disease. Together with reduction in immunosuppression, intravenous foscarnet with or without CMV hyperimmunoglobulin was the most common treatment. Drug-associated nephrotoxicity was commonly observed and resulted in allograft loss in two patients. During the mean follow-up of 2.2 yr, allograft loss and mortality occurred in two of four patients with proven and in three of five patients with clinically suspected drug-resistant CMV. CONCLUSIONS: Cytomegalovirus disease because of clinically suspected or genotypically confirmed drug-resistant CMV is not uncommon in CMV D+/R- solid organ transplant patients who received valganciclovir prophylaxis. Because of its significant morbidity and mortality, an optimized strategy of CMV prevention is warranted to reduce the negative impact of drug-resistant CMV on the successful outcome of organ transplantation.
