Заключение. Проведение ОАТ и ТПТ в динамике острой ишемии мозга позволяет получить дополнительный диагностический инструмент для дифференциации пациентов с ТИА на фоне ХИМ и оценить эффективность антитромботической терапии.
Aim: to perform a comparative analysis of hemostasis in patients with transient ischemic attack (TIA) in chronic cerebral ischemia (CCI) for optimization of diagnostics and therapy of acute ischemic cerebrovascular diseases.
Materials and methods. We examined 19 patients with TIA (not above 24 hours) and 44 patients with CCI at the fi rst day and on 8 ± 2 days of hospitalization. The control group consisted of 55 practically healthy volunteers. The parameters of lighttransmission aggregometry (LTA) of platelets and Tech-Polymer-test (TPT) were determined.
Results. Statistically signifi cant diff erences in primary and secondary hemostasis in patients with TIA and CCI were shown in comparison with parameters of healthy persons and patients with CCI without TIA.
Conclusion. Using of LTA and TPT in dynamics of acute cerebral ischemia allows to obtain an additional diagnostic instrument for differentiating patients with TIA and CCI and to evaluate the effectiveness of antithrombotic therapy.

Background: Primary management of advanced head/neck cancers involves concurrent chemoradiotherapy . Subsequently, regional and local failures are managed with resection but there have been few reports that describe the morbidity and disease control outcomes of surgical salvage in this setting. Methods: Retrospective analysis describes complications, survival, and patterns of failure after salvage resection of isolated local and/or regional failures of head/neck cancer following definitive concurrent chemoradiotherapy. Results: Sixteen patients were identified for inclusion: laryngectomy in 11 patients, oral cavity/oropharynx resection in 2 patients, and neck dissection alone in 4 patients. Ten patients required graft tissue reconstruction (6 pedicle and 4 free flap). Median post-operative hospitalization was 7 days (range 3-19), and 4 patients required hospital re-admission. At a median survivor follow-up of 15.8 months (range 4.3-34.9), 10 patients were alive (6 without evidence of disease). Seven patients experienced disease recurrence at a median 6.7 months (range 0-12.6) following salvage resection (2 with isolated distant failures). Estimated 2-year local/regional control, freedom from failure, and overall survival were 58%, 39%, and 58%, respectively. Conclusions: Surgical salvage after primary definitive concurrent chemoradiotherapy is feasible with toxicity and outcomes similar to prior radiotherapy alone or sequential chemotherapy and radiation. Local andregional recurrence remains the predominant pattern of failure.

Purpose: Brain-computer interfaces (BCI) are systems which enable direct communication between a brain and an external device by translating electrical brain activity into meaningful output. This technology can be used by individuals with motor impairments to interact and communicate with their external environment. BCIs based upon manipulating the sensorimotor rhythm (SMR) through motor imagery have lengthy learning periods, which present a significant barrier to using this technology. We hypothesize that this learning period will be significantly reduced by transcranial direct current stimulation (tDCS), which temporarily augments cortical excitability.Methods: Participants were assigned into two groups - the experimental group, which received tDCS, and a control group, which received sham stimulation. Following tDCS, the participants used a SMR-based BCI to move a falling ball to hit targets that appeared on the left or right side of screen. The effect of tDCS was assessed by comparing the overall task accuracy and the SMR change during motor imagery between the two groups .Results: The experimental group was significantly more accurate in controlling the BCI than the control group (p = 0.021); however, there was no significant difference between groups in the SMR change upon motor imagery (p = 0.22). Conclusions. tDCS can be used to improve the performance of healthy individuals learning to use an SMR-based BCI.
Clinical trial transparency at McGill University
Authors: Pradhan Richeek , Bonardi Olivia 
Published: February 2021

Transparency in clinical trials is an issue under considerable scrutiny at present, and rightfully so, given that people's lives are both used as a resource in such research and affected by its results. Hence, the results of clinical trials conducted should be made available in both journal articles and in open access trial registries (like ClinicalTrials.gov). The latter not only make research results more accessible to the general public but are also considered essential resources in systematic reviews to avoid publication bias. Yet, up to 89% of clinical trials conducted at McGill University are not reported in clinical trial registries, and up to 37% of the trials are not published. However, since most McGill University researchers use public funding to conduct trials on human subjects, they have an obligation to make their research freely accessible. Spreading awareness regarding this issue among key stakeholders is a possible way to reduce this problem and increase the transparency of clinical research at McGill University.

Published: February 2021

Induced malaria by blood transfusion is a potential health hazard but is often neglected in many malaria endemic areas. Standard parasitological technique was used to determine the prevalence of malaria among blood donors in the South-eastern Nigeria. Of the total 325 blood donors (310 males and 15 females) screened, 133 (40.9%, CI 95%: 35.6-46.2%) were infected with malaria parasite, 78 (58.6%) had 1-10 parasites per 100 thick film fields ('+' or 4-40 parasites per mm3) while 55 (41.4%) had 11-100 parasites per 100 thick film fields ('++' or 41-400 parasites per mm3). P. falciparum was identified in all the infected cases, however 3 (2.3%) persons had mixed infection with P. malariae. Males were more infected (41.3%, CI 95%: 35.8-46.8%) than females (33.3%, CI 95%: 9.4-57.2%). The infection decreased with age with highest prevalence of 48.5% among those aged 20-25 years. The infection significantly varied with age but not with sex (P<0.05). Individuals with blood group B were slightly more infected (42.1%, 95%CI., 19.6-64.6%) than those of groups O (41.0%,CI 95%: 35.3-46.7%) and A (40.0%, CI 95%: 20.8-59.2%) but there was no significant difference (P < 0.05). Highest prevalence of infection was recorded in the month of April corresponding to the onset of the wet season. An overhaul of existing blood donation policies in many health facilities in the sub-Saharan Africa to incorporate malaria screening is advocated. Curative antimalarial drugs followed by prophylactic drugs should be given to all recipients of Parasitized blood.

Published: February 2021

Background Dancers are a unique category of athletes who are frequently injured and experience pain. The primary cause of dance injuries is overuse, which could potentially be prevented. However, literature is scarce regarding validated methods of evaluating the risk of injury in dancers. The Movement Competency Screen (MCS) could potentially fill this gap. Hypothesis/Purpose To investigate the validity of the Movement Competency Screen (MCS) for dancers by 1) examining the correlation between scores on this functional test and the activation of deep abdominals and hip strength; 2) investigating the correlation between MCS scores and those of the Functional Movement Screen (FMS™). Study Design Cross-sectional study. Methods A total of 77 pre-professional and professional dancers from ballet and contemporary backgrounds were evaluated. The activation of deep abdominals was evaluated using ultrasound imaging and the hip strength was evaluated using a handheld dynamometer. The FMS™, another tool evaluating fundamental movement competency, was also administered. Results The dancers’ MCS score was correlated with the activation of the transversus abdominis (r=0.239, p=0.036) and the strength of hip abductors (r=0.293, p=0.010), adductors (r=0.267, p=0.019) and external rotators (r=0.249, p=0.029). The MCS score was also correlated with the FMS™ score (r=0.489, p<0.001). Conclusion This study shows that the MCS score is correlated with deep abdominal activation and hip strength in dancers, as well as with the FMS™ score. These findings provide evidence toward the validation of the MCS in dancers. Levels of Evidence Level 2B.

Published: February 2021

Background Self-efficacy and fear of re-injury have been documented as factors related to an athlete’s ability to return-to-sport after anterior cruciate ligament (ACL) reconstruction. The purpose of this study was to compare psychological readiness between athletes injured in their primary mode of sport versus those injured outside of their primary sport following ACL reconstruction. Hypothesis Athletes sustaining ‘in-sport’ injuries will demonstrate poorer psychological readiness when compared their matched counterparts injured outside of their primary sport. Study Design Case-Control Study Methods A single-surgeon database of 638 patients following ACL reconstruction was used to conduct a matched case-control analysis. Psychological readiness was examined 16-weeks postoperatively using the ACL-Return to Sport after Injury (ACL-RSI) questionnaire with subgroup analyses for the ‘emotional’, ‘confidence’ and ‘injury-risk’ subscales. Subject matching was performed for baseline patient and surgical demographics. All statistical comparisons were performed using a one-way (group) analysis variance (ANOVA) at a significance level of α = .05. Results Ninety-two matched patients (49 ‘in-sport’ injuries, 43 ‘out-of-sport’ injuries) were included in the final analysis. The ‘in-sport’ group exhibited significantly lower total ACL-RSI scores (55.3 ±12.9 versus 60.8 ±11.6, t = 2.747, P < .001) when compared to the ‘out-of-sport’ group. Subscale comparisons indicated lower ‘emotional’ (P < .016) and higher ‘injury risk’ (P < .001) psychological constructs for ‘in-sport’ athletes versus ‘out-of-sport’ athletes. No differences were found between groups for the ‘confidence’ subscale (P = .987). Conclusions Athletes sustaining ‘in-sport’ ACL injuries demonstrated poorer psychological readiness when compared to athletes injured outside their primary sport when in preparation for return-to-sport activities following ACL reconstruction. Clinical Relevance Clinicians should consider the potential impact of mode of injury on psychological readiness when returning athletes to sport after ACL reconstruction.
Quantifying the Burden of Shoulder and Hip Pain In Water Polo Players Across Different Playing Levels
Authors: Girdwood Michael , Webster Marilyn 
Published: February 2021

Background Water polo is characterised by unique skills and movements with high demands of both the upper and lower limb. There is growing recognition of the problems of shoulder and hip/groin symptoms in this population. Purpose To quantify the prevalence of shoulder and hip/groin pain in water polo players, and to describe how performance and participation were impacted. Secondary aims investigated whether demographic or training variables were associated with levels of symptoms. Design In-season, cross-sectional questionnaire study Methods An online questionnaire was distributed to all adult levels of the Australian water polo community. Participants were asked about demographic and playing history, and then specific injury history at both the shoulder and hip/groin. Each respondent completed an Oslo Sports Trauma Research Centre (OSTRC) overuse injury questionnaire for the shoulder and hip/groin. Point prevalence and past history were calculated, as well as a morbidity score from OSTRC responses. Risk ratios were used to determine differences between playing levels and sex. Results One hundred, fifty-three respondents completed the questionnaire (57% female). High rates of shoulder pain were reported (38.1% current, 81.2% past history), as well as hip/groin pain (33.1% current, 60.4% past history). Current shoulder pain was a risk factor for hip/groin pain (RR 1.99 (95%CI 1.27-3.12), and hip/groin pain was a risk factor for shoulder pain (RR 1.70 (95%CI 1.23-2.35). Elite-level athletes had higher prevalence (RR 1.87 [95%CI 1.01-3.46]) and past history of hip/groin pain (RR 1.76 [95%CI 1.32-2.36]). Conclusions This is the first study to quantify high self-reported levels of hip/groin pain in water polo athletes. Such high levels may be explained by high amounts of eggbeater kick, especially during skeletal development in adolescence. Shoulder pain continues to be the most common source of injury burden in water polo. Future research should determine whether any modifiable risk factors exist that may reduce the burden of injury in this population. Level of Evidence 2b

Published: February 2021

Background There are limited studies reporting descriptive strength and range of motion in youth baseball players 12 years of age or younger. Purpose To establish normative data for external (ER) and internal (IR) rotation range of motion (ROM), total arc range of motion (TROM), and isometric rotator cuff strength in youth baseball players, and to compare between the dominant throwing arm (D) to the non-dominant arm (ND). Study Design Cross-sectional Methods Patient population included 50 (5 to 12-year-old) uninjured, healthy athletes. ROM measurements were performed preseason using a goniometer for IR and ER in the supine position with the shoulder in 90 degrees of abduction (abd) with scapular stabilization. Isometric strength measurements for IR and ER were collected in both neutral and 90 degrees (deg) of abduction with the use of a hand-held dynamometer and recorded in pounds (lbs) utilizing a “make” test. Descriptive statistics were obtained for all measures. Results All data were analyzed as a single group (average age: 9.02). No significant difference in average total arc of PROM (ER+IR=Total Arc) on the D side compared to the ND side (136.7 ± 12.7 deg vs. 134.3 ± 12.3 deg). There were statistically significant differences between ER ROM (102.2 ± 7.7 deg vs. 96.8 ± 7.4 deg) and IR ROM (34.4 ± 9.0 deg vs. 37.5 ± 9.5 deg) between D versus ND arms (p= .000, .006 respectively). Mean ER strength in neutral (13.6 ± 3.4 and 12.8 ± 3.6 lbs) and 90 deg abduction (12.3 ± 3.4 and 12.5 ± 4.3 lbs) did were not significantly different between D and ND arms, respectively. Mean IR strength in neutral (18.0 ± 6.0 and 15.7 ± 4.7 lbs) and 90 deg abd (16.4 ± 5.6 and 15.0 ± 5.7 lbs) was significantly greater in the D arm vs ND arm, respectively (p=.000, .001). Conclusion These data can provide descriptive information for clinicians who treat very young baseball players. These data show sport specific adaptations occur at very young ages (5-12) and are similar to prior reports on adolescent, high school and professional baseball players regarding upper extremity ROM and rotator cuff strength.

The Utility of Neuromotor Retraining to Augment Manual Therapy and Vestibular Rehabilitation in a Patient with Post-Concussion Syndrome: A Case Report
Authors: Teare-Ketter Andrew , LaForme Fiss Alyssa , Ebert Jeffrey 
Published: February 2021

Background and Purpose Less than half of patients discharged from the emergency department post-concussion receive patient education or follow-up care, and 10-20% of individuals will develop symptoms that last longer than six months. Current research on interventions for post-concussion syndrome (PCS) shows inconsistent results, and recommendations for effective physical therapy treatment for patients with chronic PCS are lacking. The purpose of this case report is to highlight a successful, multi-system approach to physical therapy examination and treatment of a patient with chronic PCS. Case Description This case describes a 21-year-old male who sustained a concussion 356 days prior to evaluation. He received no follow-up treatment and reported periods of worsening symptoms since the injury. Impairments in cervical range of motion and accessory mobility, vestibular and vestibulo-ocular function, and postural stability were identified. Both cognitive and emotional symptoms were also present. The patient attended eight, sixty-minute sessions over a five-week period in an outpatient setting. Comprehensive physical therapy interventions included manual therapy, vestibular rehabilitation, and neuromotor retraining aimed at restoring proper sensory integration and midline postural orientation. Outcomes Outcomes included cervical spine goniometric measurements and accessory mobility assessments. Objective measures of postural stability included the Modified Clinical Test of Sensory Interaction in Balance (m-CTSIB) and the Fukuda Step Test. The Rivermead Post-Concussion Symptoms Questionnaire (RPQ) was used to subjectively assess symptom severity. At discharge, goniometric measurements returned to within normal limits except left cervical rotation active range of motion (ROM), and both the m-CTSIB and Fukuda Step Test were within normal ranges. The RPQ score reduced from 20 to 2 demonstrating symptom resolution in all items but “headache.” Discussion PCS can affect multiple systems, necessitating a comprehensive approach to examination and intervention. Manual therapy was used to restore cervical spine ROM, vestibular rehabilitation was utilized to improve gaze stability and visual motion sensitivity, and neuromotor retraining was implemented to improve postural stability and sensory integration. Physical therapists have the ability to treat multiple systems impacted with PCS, with the potential to reduce the longevity and severity of impairments for patients. Level of Evidence Level V

Published: February 2021

It has been debated that effective essential public services delivery is crucial to inculcate inclusive growth in cities over the past decades. Cities continue to be central to the debate; however, the current study focuses on industrial towns. As industrial towns' development around cities attract investment and promote economic growth, the present research studies the impact of essential public services delivery on promoting inclusive growth for inhabitants of industrial towns in developing countries. Human Capabilities Dimension Approach and its parameters (Social and Physical Infrastructure) have been employed to explore the role of basic amenities in transferring growth levels across all population sections. The idea explored is studied through Mandideep Industrial Town's case study, where six parameters (Physical and socioeconomic status, water supply, sanitation, health care facilities, education facilities), and perceived inclusive growth have been considered for data collection and analysis. Indicators under each parameter are analyzed based on the 4A's-Availability, Accessibility, Awareness, and Affordability. Site selection revolved around a city reconnaissance survey and Household survey for 200 households. Aggregated analysis for the city and ward-wise comparative analysis and statistical correlation tools were used to establish a relationship between basic public services delivery and perceived inclusive growth. The research aims to study and establish a correlation between public service delivery and perceived inclusive growth by the industrial town's inhabitants. Discussions following data analysis led to recommendations for city and ward-level. The importance of efficient service delivery for increased perception of inclusive growth is established. Along with the six parameters considered for the study, physical and environmental planning emerge as crucial parameters that impact other public services for enhanced inclusive growth in industrial cities.
