Published: March 2017

Background:A retear is a significant clinical problem after rotator cuff repair. However, no study has evaluated the retear rate with regard to the extent of footprint coverage.Purpose:To evaluate the preoperative and intraoperative factors for a retear after rotator cuff repair, and to confirm the relationship with the extent of footprint coverage.Study Design:Cohort study; Level of evidence, 3.Methods:Data were retrospectively collected from 693 patients who underwent arthroscopic rotator cuff repair between January 2006 and December 2014. All repairs were classified into 4 types of completeness of repair according to the amount of footprint coverage at the end of surgery. All patients underwent magnetic resonance imaging (MRI) after a mean postoperative duration of 5.4 months. Preoperative demographic data, functional scores, range of motion, and global fatty degeneration on preoperative MRI and intraoperative variables including the tear size, completeness of rotator cuff repair, concomitant subscapularis repair, number of suture anchors used, repair technique (single-row or transosseous-equivalent double-row repair), and surgical duration were evaluated. Furthermore, the factors associated with failure using the single-row technique and transosseous-equivalent double-row technique were analyzed separately.Results:The retear rate was 7.22%. Univariate analysis revealed that rotator cuff retears were affected by age; the presence of inflammatory arthritis; the completeness of rotator cuff repair; the initial tear size; the number of suture anchors; mean operative time; functional visual analog scale scores; Simple Shoulder Test findings; American Shoulder and Elbow Surgeons scores; and fatty degeneration of the supraspinatus, infraspinatus, and subscapularis. Multivariate logistic regression analysis revealed patient age, initial tear size, and fatty degeneration of the supraspinatus as independent risk factors for a rotator cuff retear. Multivariate logistic regression analysis of the single-row group revealed patient age and fatty degeneration of the supraspinatus as independent risk factors for a rotator cuff retear. Multivariate logistic regression analysis of the transosseous-equivalent double-row group revealed a frozen shoulder as an independent risk factor for a rotator cuff retear.Conclusion:Our results suggest that patient age, initial tear size, and fatty degeneration of the supraspinatus are independent risk factors for a rotator cuff retear, whereas the completeness of rotator cuff repair based on the extent of footprint coverage and repair technique are not.

Published: March 2017

Purpose: This study contributes to the emerging literature on lesbian, gay, bisexual, transgendered, and queer (LGBTQ) health disparities and tobacco use by examining the motivations for smoking among the New York City (NYC) LGBTQ population. Approach: We used grounded theory and blended methods from 3 grounded theorists—Strauss, Corbin, and Charmaz—for data collection, coding, and analysis. Setting: NYC has extensive legislation to prevent smoking; however, the current smoking prevalence of homosexuals is double that of heterosexuals. Participants: Study participants were leaders from 23 NYC LGBTQ organizations. Leaders were chosen to establish a relationship with community and to ensure cultural sensitivity. Eligibility criteria required holding a leadership position in an organization serving the NYC LGBTQ community. Methods: Interviews were transcribed verbatim and uploaded into Dedoose for analysis. An initial code list was developed from the interview guide. Key themes were identified as the themes with the most number of quotes. Results: Three key themes emerged from our interviews: image, socializing, and stress. Smoking was reported to be a socialization aid and a maladaptive coping technique for stress arising from interactions of conflicting identities. Conclusion: Future smoking cessation interventions among the LGBTQ community should equip smokers with healthy coping mechanisms that address the stressors that arise from the intersections of smokers’ many identities.

Purpose: The purpose of this study was to examine the associations between physical education (PE) and sports involvement with physical activity (PA), physical fitness, and beliefs about PA among a national sample of adolescents. Setting: Data from the National Health and Nutrition Examination Survey National Youth Fitness Survey were used. Participants: A total of 459 adolescents aged 12 to 15 years. Measures: Adolescents self-reported engagement in the above parameters; muscular fitness objectively determined. Analysis: Multivariable linear regression. Results: Adolescents who had PE during school days had a higher enjoyment of participating in PE (β = 0.32; P = .01), engaged in more days of being physically active for ≥60 min/d (β = 1.02; P < .001), and performed the plank fitness test longer (β = 17.2; P = .002). Adolescents who played school sports reported that more PA was needed for good health (β = 0.23; P = .04), had a higher enjoyment of participating in PE (β = 0.31; P = .003), engaged in more days of being physically active for ≥60 min/d (β = 0.70; P = .01), performed more pull-ups (β = 2.33; P = .008), had a stronger grip strength (β = 2.5; P = .01), and performed the plank fitness test longer (β = 11.6; P = .04). Conclusion: Adolescents who had PE during school, who had more frequent and long-lasting PE, and who played school sports generally had more accurate perceptions of the amount of PA needed for good health, had greater enjoyment of PE, were more physically active, and performed better on several muscular fitness-related tests. This underscores the importance of PE integration in the schools and encouragement of school sports participation.
Validation of a Theory of Planned Behavior-Based Questionnaire to Examine Factors Associated With Milk Expression
Authors: Bai Yeon K. , Dinour Lauren M. 
Published: March 2017

Background: A proper assessment of multidimensional needs for breastfeeding mothers in various settings is crucial to facilitate and support breastfeeding and its exclusivity. The theory of planned behavior (TPB) has been used frequently to measure factors associated with breastfeeding. Full utility of the TPB requires accurate measurement of theory constructs. Research aim: This study aimed to develop and confirm the psychometric properties of an instrument, Milk Expression on Campus, based on the TPB and to establish the reliability and validity of the instrument. Methods: In spring 2015, 218 breastfeeding (current or in the recent past) employees and students at one university campus in northern New Jersey completed the online questionnaire containing demography and theory-based items. Internal consistency (α) and split-half reliability ( r) tests and factor analyses established and confirmed the reliability and construct validity of this instrument. Results: Milk Expression on Campus showed strong and significant reliabilities as a full scale (α = .78, r = .74, p < .001) and theory construct subscales. Validity was confirmed as psychometric properties corresponded to the factors extracted from the scale. Four factors extracted from the direct construct subscales accounted for 79.49% of the total variability. Four distinct factors from the indirect construct subscales accounted for 73.68% of the total variability. Conclusion: Milk Expression on Campus can serve as a model TPB-based instrument to examine factors associated with women’s milk expression behavior. The utility of this instrument extends to designing effective promotion programs to foster breastfeeding and milk expression behaviors in diverse settings.
Intra-speaker variation in Chinese–English code-switching: The interaction between cognitive and contextual factors
Authors: Liu Hong 
Published: March 2017

Aims and objectives: This study examines intra-speaker variation in code-switching (CS) by comparing the frequency and pattern of CS across two different interaction modes (interview speech and online posting) based on the same individuals. This study also explores the reasons why these speakers exploit their linguistic repertoire variably in different modes. Methodology: I interviewed 40 Chinese–English bilinguals based in London and collected their speech data by recording the semi-structured interviews. Written data were obtained by collecting the participants’ posts on Sinaweibo, a popular Chinese social media. A detailed questionnaire was also administered among the participants to gather information on their language attitudes and other social backgrounds. Data and analysis: For each participant, 30 minutes of the interview were analyzed and 50 posts were chosen for written CS analysis. Quantitative analyses were performed to describe the frequency and pattern of CS. The use of CS across interaction modes was further compared and analyzed against the specific characteristics of each mode and also against the participants’ language attitudes. Findings: Results of quantitative analyses show that these participants used significantly more amount and more complex pattern of CS in their online posting. The suggested reason points to an elevated processing demand which is related to the nature of bilingualism and the level of synchronicity of interaction mode. Results of qualitative analyses also suggest that the participants’ positive attitudes towards CS and English language, both overtly expressed and covertly implied, contributed to the varying degree of CS use. Originality: This study is among the first attempts to compare CS data across different interaction modes based on same individuals. Comparative data of this kind are quite scarce in the international literature. Significance/implications: The findings highlight and provide insights into the dynamic interactions between social, cognitive, and situational factors under the surface of linguistic practice.

Purpose: To evaluate the impact of a new angiographic imaging technology on radiation dose during visceral embolization procedures involving both fluoroscopy and digital subtraction angiography. Material and Methods: A retrospective analysis from a single-center consecutive series of patients was performed comparing 2 angiographic imaging systems. The AlluraClarity (CIQ; Philips Healthcare, Best, the Netherlands) was used in 100 patients (n = 59 male, mean age: 70.6 years) from July 2013 to April 2014 and compared to the former AlluraXper (AX) technology used in 139 patients (n = 71 male, mean age: 70.1 years) from May 2011 to June 2013. Patients were categorized according to body mass index (BMI [kg/m2])—group 1: BMI <25, group 2: BMI ≥25 and <30, and group 3: BMI ≥30. Fluoroscopy time, the total dose of iodinated contrast administered, and procedural AirKerma (Ka, r [mGy]) were obtained. Results: Mean BMI was 26.4 ± 5.0 kg/m2 in the CIQ and 26.4 ± 7.1 kg/m2 in the AX group ( P = .93). Fluoroscopy time and the amount of contrast media were equally distributed. Ka, r was 1342.9 mGy versus 2214.8 mGy ( P < .001, t test) when comparing CIQ to AX. Comparing CIQ to AX, BMI subgroup analysis revealed a mean Ka, r of 970.1 to 1586.1 mGy ( P = .003, t test), 1484.7 to 2170.1 mGy ( P = .02, t test), and 1848.8 to 3348.9 mGy ( P = .001, t test) in BMI groups 1, 2, and 3, respectively. Conclusion: The CIQ technology significantly reduced mean radiation dose by 39.4% for visceral embolization procedures when compared to fluoroscopy time and contrast media dose. This dose relationship was consistent across all BMI groups.
Concomitant Staple Aneurysmorrhaphy and Flow-Calibrated Arteriovenous Fistula Banding Over a Coronary Dilator to Treat Hand Steal Syndrome
Authors: Baker Jennifer , Malgor Rafael D. 
Published: March 2017

Background: True venous aneurysm formation can occur in patients with arteriovenous fistulas (AVFs) for hemodialysis but association with steal syndrome is uncommon. Methods: To describe a case of a patient on chronic hemodialysis through a right brachiocephalic fistula, who presents with associated steal syndrome and true arteriovenous access aneurysm. Results: A 34-year-old female with true AVF aneurysm presented with hand steal syndrome confirmed by noninvasive studies. The patient underwent a successful vein aneurysmorrhaphy with a commercially available stapler device and duplex ultrasound flow-calibrated banding. At 1-year follow-up, she remains pain free and the fistula remains functional with no recurrence of venous aneurysmal degeneration. Conclusion: The use of a commercially available surgical stapler devices along with flow-calibrated banding guided by duplex ultrasound over a coronary dilator during the same operation is an elegant, efficacious, and a durable alternative for patients with hand steal syndrome and concomitant AVF aneurysms.
Citation of prior research has increased in introduction and discussion sections with time: A survey of clinical trials in physiotherapy
Authors: Hoderlein Xenia , Moseley Anne M , Elkins Mark R 
Published: March 2017

Background/aims: Many clinical trials are reported without reference to the existing relevant high-quality research. This study aimed to investigate the extent to which authors of reports of clinical trials of physiotherapy interventions try to use high-quality clinical research to (1) help justify the need for the trial in the introduction and (2) help interpret the trial’s results in the discussion. Methods: Data were extracted from 221 clinical trials that were randomly selected from the Physiotherapy Evidence Database: 70 published in 2001 (10% sample) and 151 published in 2015 (10% sample). The Physiotherapy Evidence Database score (which rates methodological quality and completeness of reporting) for each trial was also downloaded. Results: Overall 41% of trial reports cited a systematic review or the results of a search for other evidence in the introduction section: 20% for 2001 and 50% for 2015 (relative risk = 2.3, 95% confidence interval = 1.5–3.8). For the discussion section, only 1 of 221 trials integrated the results of the trial into an existing meta-analysis, but citation of a relevant systematic review did increase from 17% in 2001 to 34% in 2015. There was no relationship between citation of existing research and the total Physiotherapy Evidence Database score. Conclusion: Published reports of clinical trials of physiotherapy interventions increasingly cite a systematic review or the results of a search for other evidence in the introduction, but integration with existing research in the discussion section is very rare. To encourage the use of existing research, stronger recommendations to refer to existing systematic reviews (where available) could be incorporated into reporting checklists and journal editorial guidelines.

Published: March 2017

Background Quantitative ultrasound imaging is gaining popularity in research and clinical settings to measure the neuromechanical properties of the peripheral nerves such as their capability to glide in response to body segment movement. Increasing evidence suggests that impaired median nerve longitudinal excursion is associated with carpal tunnel syndrome. To date, psychometric properties of longitudinal nerve excursion measurements using quantitative ultrasound imaging have not been extensively investigated. Methods This study investigates the convergent validity of the longitudinal nerve excursion by comparing measures obtained using quantitative ultrasound imaging with those determined with a motion analysis system. A 38-cm long rigid nerve-phantom model was used to assess the longitudinal excursion in a laboratory environment. The nerve-phantom model, immersed in a 20-cm deep container filled with a gelatin-based solution, was moved 20 times using a linear forward and backward motion. Three light-emitting diodes were used to record nerve-phantom excursion with a motion analysis system, while a 5-cm linear transducer allowed simultaneous recording via ultrasound imaging. Results Both measurement techniques yielded excellent association ( r = 0.99) and agreement (mean absolute difference between methods = 0.85 mm; mean relative difference between methods = 7.48 %). Small discrepancies were largely found when larger excursions (i.e. > 10 mm) were performed, revealing slight underestimation of the excursion by the ultrasound imaging analysis software. Conclusion Quantitative ultrasound imaging is an accurate method to assess the longitudinal excursion of an in vitro nerve-phantom model and appears relevant for future research protocols investigating the neuromechanical properties of the peripheral nerves.

Background Accumulating evidence on the causal role of spinal cord microglia activation in the development of neuropathic pain after peripheral nerve injury suggests that microglial activation inhibitors might be useful analgesics for neuropathic pain. Studies also have shown that polyamidoamine dendrimer may function as a drug delivery vehicle to microglia in the central nervous system. In this regard, we developed polyamidoamine dendrimer-conjugated triamcinolone acetonide, a previously identified microglial activation inhibitor, and tested its analgesic efficacy in a mouse peripheral nerve injury model. Result Polyamidoamine dendrimer was delivered selectively to spinal cord microglia upon intrathecal administration. Dendrimer-conjugated triamcinolone acetonide inhibited lipoteichoic acid-induced proinflammatory gene expression in primary glial cells. In addition, dendrimer-conjugated triamcinolone acetonide administration (intrathecal) inhibited peripheral nerve injury-induced spinal cord microglial activation and the expression of pain-related genes in the spinal cord, including Nox2, IL-1β, TNF-α, and IL-6. Dendrimer-conjugated triamcinolone acetonide administration right after nerve injury almost completely reversed peripheral nerve injury-induced mechanical allodynia for up to three days. Meanwhile, dendrimer-conjugated triamcinolone acetonide administration 1.5 days post injury significantly attenuated mechanical allodynia. Conclusion Our data demonstrate that dendrimer-conjugated triamcinolone acetonide inhibits spinal cord microglia activation and attenuates neuropathic pain after peripheral nerve injury, which has therapeutic implications for the treatment of neuropathic pain.

Objective:The objective was to investigate glycemic variability indices in relation to demographic factors and common environmental lifestyles in a general adult population.Methods:The A Estrada Glycation and Inflammation Study is a cross-sectional study covering 1516 participants selected by sampling of the population aged 18 years and over. A subsample of 622 individuals participated in the Glycation project, which included continuous glucose monitoring procedures. Five glycemic variability indices were analyzed, that is, SD, MAGE, MAG, CONGA1, and MODD.Results:Participants had a mean age of 48 years, 62% were females, and 12% had been previously diagnosed with diabetes. In the population without diabetes, index distributions were not normal but skewed to the right. Distributional regression models that adjusted for age, gender, BMI, alcohol intake, smoking status, and physical activity confirmed that all indices were positively and independently associated with fasting glucose levels and negatively with heavy drinking. SD, MAGE, and CONGA1 were positively associated with aging, and MAG was negatively associated with BMI. None of the GVI studied were influenced by physical activity. Age-group-specific reference values are given for the indices.Conclusions:This study yielded age-specific reference values for glucose variability indices in a general adult population. Significant increases were observed with aging. Heavy drinking of more than 140 g/week was associated with significant decreases in variability indices. No differences were found between males and females. These normative ranges provide a guide for clinical care, and may offer an alternative treatment target among persons with diabetes.
Correlation between hemoglobin A1c and serum lipid profile in Afghani patients with type 2 diabetes: hemoglobin A1c prognosticates dyslipidemia
Authors: Hussain Arshad , Ali Iftikhar , Ijaz Muhammad , Rahim Afaq 
Published: March 2017

Background: Patients with type 2 diabetes (T2DM) have an increased prevalence of dyslipidemia, which contributes to their high risk of cardiovascular diseases (CVDs). This study is an attempt to determine the correlation between hemoglobin A1c (HbA1c) and serum lipid profile and to evaluate the importance of HbA1c as an indicator of dyslipidemia in Afghani patients with T2DM. Methods: A total of 401 Afghani patients with T2DM (men, 175; women, 226; mean age, 51.29 years) were included in this study. The whole blood and sera were analyzed for fasting blood sugar (FBS), HbA1c, total cholesterol (TC), triglycerides (TGs), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). Dyslipidemia was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) guidelines. Diabetes was defined as per American Diabetes Association criteria. The correlation of FBS, HbA1c with lipid ratios and individual lipid indexes were analyzed. The statistical analysis was done by SPSS statistical package version 16.0. Results: The mean age ± standard deviation of male and female patients were 51.71 ± 11.70 and 50.97 ± 10.23 years respectively. There was a significant positive correlation between HbA1c, TC, TG, LDL-C and LDL-C/HDL-C ratio. The correlation between HbA1c and HDL-C was negative and was statistically nonsignificant. Furthermore, HbA1c was found to be a predictor of hypercholesterolemia, LDL-C and TG via a linear regression analysis. Patients with HbA1c value greater than 7.0% had significantly higher value of cholesterol, LDL-C, and LDL-C/HDL-C ratio compared with patients with an HbA1c value up to 7.0%. Conclusions: Apart from a reliable glycemic index, HbA1c can also be used as a predictor of dyslipidemia and thus early diagnosis of dyslipidemia can be used as a preventive measure for the development of CVD in patients with T2DM.
