Altered scapular movement in subacromial pain syndrome has been demonstrated using discrete data reduction approach. However, this approach does not consider the data collinearity and variability, and scapular translations are poorly investigated in symptomatic individuals. The purpose of this study was to investigate the scapular rotation and translation of asymptomatic individuals and those with subacromial pain syndrome during arm motions using principal component analysis. Scapulothoracic kinematics were evaluated in 47 participants with subacromial pain syndrome and 50 asymptomatic individuals. The symptomatic group had increased range of scapular anterior/posterior tilt during arm elevation (P = .01, effect size = .59) and arm lowering (P < .01, effect size = .61), and increased range of scapular forward/backward translation during arm lowering (P < .01, effect size = .60) compared with the asymptomatic group. In addition, the symptomatic group had a reduced difference in anterior tilt angular velocities between the early-arm and mid-arm lowering phases and between the mid- and late-arm lowering phases compared with the asymptomatic group (P = .03, effect size = .44). This study demonstrated that scapular anterior/posterior tilt motion and angular velocity and scapular forward/backward translation of symptomatic individuals were different from asymptomatic individuals when considering the entire arm movement.

The COVID-19 pandemic has cost a large number of lives worldwide. Most of the COVID-19 patients recover within two weeks of illness, but many survivors are experiencing different post COVID-19 clinical complications. In this cross-sectional retrospective study, we investigated the immediate and post COVID-19 complications with secondary effects in symptomatic and asymptomatic COVID-19 patients of Bangladesh. A total of 632 patients diagnosed with COVID-19 from December, 2020 to February, 2021 were included in this study. The data were collected by telephone interview with patients consent and reviewing their call records using questionnaire and checklist. Results demonstrate that among the 632 patients, 77.53 % of cases were symptomatic, where fever was the most common symptom (82.24%). The other symptoms were headache (58.16%), sore throat (53.65%), cough (45.51%), weakness (41.22%), breathlessness (40%), loss of smell (37.55%), tastelessness (31.84%), diarrhea (19.39%), and vomiting (14.69%). Comorbidities like asthma, hypertension, diabetes mellitus (DM), cardiovascular disease, and other chronic diseases were pronounced in symptomatic patients. Post COVID-19 complications varied significantly (P<0.05) between the symptomatic and asymptomatic observations. Asthma, hypertension, and diabetes were newly reported in symptomatic patients with the rate of 3.06 %, 2.45 %, and 2.24 %, respectively, while the proportions were 1.41%, 1.41%, and 0.70% for the asymptomatic group. Tiredness, weight loss, hair loss, and insomnia were the most observed post COVID-19 complications found higher in symptomatic patients than in asymptomatic groups. A newly developed visual anomaly was also identified in the symptomatic group (1.42%), which was absent in asymptomatic COVID-19 recovered patients. These findings concluded that post-COVID-19 complications were high in symptomatic and comorbid patients compared with asymptomatic individuals. We hope that this study will contribute in post COVID-19 management and help the concerned authority toward decision making in the treatment of post-COVID-19 complications. Asian J. Med. Biol.

Histopathological Results

Deformed wing virus (DWV) is capable of infecting honeybees at every stage of development causing symptomatic and asymptomatic infections. To date, very little is known about the histopathological lesions caused by the virus. Therefore, 40 honeybee samples were randomly collected from a naturally DWV infected hive and subjected to anatomopathological examination to discriminate between symptomatic (29) and asymptomatic (11) honeybees. Subsequently, 15 honeybee samples were frozen at −80° and analyzed by PCR and RTqPCR to determinate the presence/absence of the virus and the relative viral load, while 25 honeybee samples were analyzed by histopathological techniques. Biomolecular results showed a fragment of the expected size (69bp) of DWV in all samples and the viral load was higher in symptomatic honeybees compared to the asymptomatic group. Histopathological results showed degenerative alterations of the hypopharyngeal glands (19/25) and flight muscles (6/25) in symptomatic samples while 4/25 asymptomatic samples showed an inflammatory response in the midgut and the hemocele. Results suggest a possible pathogenic action of DWV in both symptomatic and asymptomatic honeybees, and a role of the immune response in keeping under control the virus in asymptomatic individuals.

AbstractTo evaluate the surgical effect on survival in patients with incidental low-grade glioma (LGG) through comparison between asymptomatic and symptomatic patients. The medical records of surgically treated adult cerebral incidental LGG (iLGG) patients in our department between January 2008 and December 2015 were retrospectively reviewed. The survival of patients was calculated starting from the initial imaging diagnosis. Factors related to progression-free survival (PFS), overall survival (OS) and malignant progression-free survival (MPFS) were statistically analyzed. Seventy-five iLGG patients underwent surgery: 49 in the asymptomatic group, who underwent surgery in the asymptomatic period, and 26 in the symptomatic group, who underwent surgery after the tumor had grown and the patients had developed tumor-related symptoms. Significantly more tumors were initially located adjacent to the functional area in the symptomatic group than in the asymptomatic group (P < 0.05), but there was no significant difference in the total resection rate between the two groups. The incidence of postoperative complications (15.4%) and postoperative epilepsy (23.1%) was higher in the symptomatic group than in the asymptomatic group (4.1% and 10.2%, respectively). Multivariate analysis showed that surgical timing, namely, surgery performed before or after symptom occurrence, had no significant effect on PFS, OS or MPFS, while total resection significantly prolonged PFS, OS and MPFS, and the pathology of oligodendroglioma was positively correlated with PFS and OS (P < 0.05). Surgical timing for iLGGs should facilitate total resection. If total resection can be achieved, even after symptom occurrence, patients can achieve comparable survival benefits to those treated with surgery in the asymptomatic phase.

BACKGROUD: Reliable scapular upward rotation and anterior-posterior tilt data are required for patients with subacromial impingement syndrome (SIS). Only a few studies have explored the reliability of such measurements derived using a modified inclinometer. OBJECTIVES: To determine the relative and absolute reliability of scapular upward rotation and anterior-posterior tilt measurements derived using a modified digital inclinometer in patients with SIS. METHOD: Seventeen SIS patients were assessed twice within 1 week. We determined the relative and absolute measurement reliability by calculating the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal clinically important difference (MCID). Both intra- and interrater reliability were determined. RESULTS: The intra-rater reliability (both measurements) was high (0.72–0.88), and the interrater ICC was high to excellent (0.72–0.98). Clinically acceptable SEM and MCID values were obtained for scapular upward rotation (SEM: 4.28–9.33∘, MCID: 5.1–11.3∘) and anterior-posterior tilt (SEM: 3.72–7.55∘, MCID: 2.5–10.8∘). CONCLUSIONS: Measurements of scapular upward rotation and anterior-posterior tilt using a modified digital inclinometer reliably reveal scapular position and kinematics in patients with SIS.

Background Subacromial pain syndrome (SPS) is a common cause of shoulder pain and muscle activity deficits are postulated to contribute to the development and progression of the disorder. The purpose of this systematic review was to definitively determine whether evidence exists of differences in electromyography (EMG) characteristics between subjects with and without SPS. Methods Six key databases were searched: MEDLINE, EMBASE, CINAHL, SPORTdiscus, PEDro and The Cochrane Library (inception to May 2016). The search yielded 1414 records using terms relating to shoulder impingement, EMG, scapular and rotator cuff muscles. Twenty-two papers remained once duplicates were removed and selection criteria applied. Data extraction, quality assessment and data synthesis were performed. Effect sizes and 95% confidence intervals were calculated. Results There was limited evidence that serratus anterior has lower amplitude, delayed activation and earlier termination in SPS participants. For the majority of muscles, regardless of task, load or arm position, significant differences were not demonstrated or results were contradictory. Conclusions The understanding of SPS is changing and EMG appears unable to capture the complexities associated with this condition. Addressing aberrant movement patterns and facilitating balanced activation of all shoulder muscles may be a more appropriate treatment direction for the future.
