Authors: Bradley James P. , Arner Justin W. , Jayakumar Sachidhanand , Vyas Dharmesh 
Published: July 2018

Background: Risk factors and outcomes of revision arthroscopic posterior capsulolabral repair of the shoulder are currently not well defined. Hypothesis: Athletes who require revision arthroscopic posterior unidirectional capsulolabral repair will have poorer outcomes and return to play when compared with those undergoing primary procedures, with risk factors including younger age, injury size, bone loss, and anchor number. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 297 shoulders that underwent arthroscopic posterior capsulolabral repair at minimum 2-year follow-up were reviewed. In addition to surgical data, the American Shoulder and Elbow Surgeons scoring system with subjective stability, range of motion, strength, and pain scores as well as return to sport were compared pre- and postoperatively between those who did and did not require revision surgery. Magnetic resonance arthrogram measurements of glenoid labral, chondral, and bone version and labral and bone width were also compared. Results: Nineteen shoulders required revision surgery (6.4%) at 8.9-year follow-up. Significant risk factors included female sex ( P = .001), dominant shoulder ( P = .005), and concomitant rotator cuff injury ( P = .029). Patients with ≤3 anchors were more likely to require revision (odds ratio = 3.48). Smaller glenoid bone width was a risk factor for requiring future revision surgery ( P < .001), but glenoid labral, chondral, and bone version and labral width were not risk factors. All patients had significant improvements in American Shoulder and Elbow Surgeons, pain, range of motion, and strength scores after the original surgery; however, those who required revision surgery had less improvement ( P < .05). Stability improved significantly for nonrevisions ( P < .001) but did not for revisions ( P = .662). In the nonrevision group, 64.3% returned to sport at the same level, which was significantly higher than the 15.4% of the revision group ( P = .004). Overall, 78.6% of the nonrevision group and 61.6% of the revision group returned to sport at some level ( P = .280). Conclusion: Athletes underwent revision arthroscopic posterior capsulolabral repair at an incidence of 6.4%. Revision patients had significantly poorer outcome scores and return to play when compared with those who did not undergo revision surgery with risk factors being dominant shoulder surgery, female sex, concomitant rotator cuff injury, the use of 3 or fewer anchors, and smaller glenoid bone width. These data are essential for patient selection, optimal treatment techniques, and patient education as posterior shoulder instability failure requiring revision has not previously been evaluated.

Published: July 2018

Purpose: To evaluate the association between preconception care and the risk of adverse birth outcomes. Design: A quasi-experimental study comparing 2 groups: (1) integrated maternal health care (MHC) program (with preconception care) and (2) standard MHC program (without preconception care). Setting: Maternal health-care clinics in Alvand and Qazvin cities in Qazvin Province, Iran. Participants: A total of 152 and 247 Iranian women aged 16 to 35 years were enrolled in the integrated MHC and standard MHC program, respectively. Measures: The birth outcomes measured included low birth weight, preterm birth, maternal and neonatal complications, and mode of delivery (normal vaginal delivery and cesarean delivery). Analysis: Multiple logistic regression was performed to determine the impact of preconception care and risk of adverse birth outcomes with adjusted odds ratios (ORs) as effect sizes. Results: One hundred forty-seven women in integrated MHC and 218 women in standard MHC completed this study. Preconception care was associated with reduced risk of preterm birth (OR = 0.298; 95% confidence interval [CI] = 0.120-0.743; P = .009), low birth weight (OR = 0.406; 95% CI = 0.169-0.971; P = .043), maternal complication (OR = 0.399; 95% CI = 0.241-0.663; P < .001), and neonatal complications (OR = 0.460; 95% CI = 0.275-0.771; P = .003). Conclusion: The findings of the present study revealed advantages of preconception care with reduced adverse birth outcomes.

Purpose: This study aimed to measure healthy lifestyle for European adults. Design: Cross-sectional study. Settings: In 20 European countries. Participants: A total of 34 993 (16 749 men, 18 244 women) European adults. Measures: Data were from the 2014 European Social Survey (n = 34 993) on 4 modifiable behaviors (physical activity, fruit and vegetable consumption, not drinking alcohol to excess, and not smoking) as well as sleep quality. Analysis: Behaviors were combined and formed a healthy lifestyle measure. Binary logistic regression was done to determine associations of healthy lifestyle and sociodemographic characteristics. Results: Only 5.8% of the adults reported a healthy lifestyle. The prevalence of having a healthy lifestyle varied among European countries. The lowest rates were in Hungary (1.3%) and Czech Republic (1.9%). The highest rates were in United Kingdom (8.6%) and Finland (9.2%). Those who presented a higher likelihood of having a healthy lifestyle were middle age (odds ratio [OR] = 1.20), older people (OR = 1.34), having higher household income (OR = 1.33), being a student (OR = 1.38), and retired (OR = 1.31). Those less likely to have a healthy lifestyle were lived without a partner (OR = 0.82), unemployed (OR = 0.73), and lived in rural areas (OR = 0.86). Conclusions: Few European adults were practicing 5 healthy behaviors. This should be a message for governments and be considered in the establishment of preventive public policies in the areas of health and health education.

Published: July 2018

In this work, activities of modified dolomite catalysts using calcium acetate in the heterogeneously catalyzed transesterification of microalgae oil with methanol were investigated. Modified catalysts were prepared via wet impregnation method and calcined 850°C for 2 h. Reaction conditions were examined as the catalyst type, amount of catalyst, methanol/microalgae oil molar ratio, and reusability of the catalyst using the dolomite and modified dolomite catalysts. When investigated reusability of the modified dolomite catalyst in the transesterification of microalgae oil with methanol, catalyst was reused three times with a small loss of activity. After fourth run, reused catalyst was calcined again and got similar activity to the first run. The highest fatty acid methyl esters (FAME) yield of 90% was obtained when the reaction was performed with methanol/microalgae oil molar ratio of 6:1, catalyst amount of 3%, and reaction temperature at 65°C for 3 h by using the 30% CaO/dolomite catalyst.

Published: July 2018

Objective: This study aimed to compare, using optical coherence tomography (OCT), the outcomes of bioabsorbable drug-eluting stent with those of bare metal stent (BMS) following implantation in porcine iliac artery. Methods: After the placement of BMS and bioabsorbable drug-eluting stents, we used OCT and digital subtraction angiography to investigate stent appositions, arterial neointima, evagination, and restenosis at 1 and 3 months. Results: At 1 and 3 months after stent implantation, OCT study was performed to investigate 32 stents and 21 788 struts. Thirty-three malapposed struts were found in the bioabsorbable drug-eluting stent groups and 2 were found in BMS groups. The average neointimal thickness, area, and in-stent stenosis were significantly lower in bioabsorbable drug-eluting stents than in BMS, while the frequency of malapposed struts was higher in the bioresorbable drug-eluting stent groups. Average neointimal thickness was lower in bioabsorbable drug-eluting stents than in BMS at 1 (0.19 ± 0.09 vs 0.67 ± 0.75 mm; P < .001) and 3 months (0.21 ± 0.08 vs 1.52 ± 0.28 mm; P < .001). Conclusion: Our study suggested that bioabsorbable drug-eluting stent is more effective in decreasing arterial restenosis than BMS in animal models.

Introducción: La terapia sistémica para el cáncer de mama afecta la calidad de vida de las mujeres y sus familias. Se analizó la influencia de los factores personales sobre la percepción de calidad de vida de mujeres en tratamiento para el cáncer mamario. Métodos: Participaron noventa y cinco asistentes a la consulta de un hospital público del noreste de México. Se aplicaron dos Cuestionarios de la Organización Europea para la Investigación y Tratamiento del Cáncer (EORTC QLQ-C30 y EORTC QLQ-BR23). Resultados: La edad promedio fue de 55 años ( DE = 9.24). Las participantes destacaron por presentar valores altos para el estado de salud global y niveles bajos en funcionamiento ( rango = 11.71 a 18.42). El insomnio y el impacto económico fueron las áreas más afectadas. Con el incremento de la edad, se observó menor afectación por síntomas mamarios, función y el disfrute sexual ( r = −.273, −.349 y −.304 respectivamente, p < .01). Conclusión: La situación laboral, estado civil, paridad y lugar de procedencia promovieron afectación diferencial en algunos síntomas incluyendo la imagen corporal. La aplicación de estos cuestionarios permitiría la identificación de necesidades de cuidado físico u emocional en la práctica clínica.
Three-year recurrence of Dupuytren’s contracture after needle fasciotomy and collagenase injection: a two-centre randomized controlled trial
Authors: Scherman Peter , Jenmalm Per , Dahlin Lars B. 
Published: July 2018

Collagenase injection and needle fasciotomy have similar short-term outcomes in the treatment of Dupuytren’s contracture. The purpose of this study was to compare the recurrence rate of these two procedures 3 years after index treatment of primary disease. We enrolled 93 patients (96 rays) from a previous two-centre randomized controlled trial. The rays that had been retreated or showed an increase in the total passive extension deficit of 30° or more compared with 3 months after treatment were regarded as recurrences. Seventeen of 40 needle fasciectomies and 12 of 36 of collagenase injections had recurred. This difference was not statistically significant. We conclude that collagenase injection and needle fasciotomy have similar 3-year recurrence rates in the treatment of Dupuytren’s contracture. Level of evidence: I

Published: July 2018

Ankle fractures are common orthopaedic injuries often requiring open reduction and internal fixation. A variety of positions for plate placement exist for surgical fixation of distal fibula fractures, including direct lateral, posterior, or posterolateral. Direct lateral is more common, despite evidence that posterior and posterolateral placement is mechanically superior. However, concern for peroneal tendon injury from posterior plating remains. Our study investigates clinical and functional outcomes of patients who underwent operative fixation of distal fibula fractures with posterior or posterolateral plating over a 3-year period. Analyses were performed on 59 patients with at least 2 years of follow-up. Questionnaires were used to obtain demographic data, in addition to information regarding the presence of ankle pain, subsequent hardware removal, and Foot and Ankle Outcome Scores (FAOS). In patients with at least 2 years of follow-up (average 39.6 ± 10.6 months), 37.2% reported ongoing ankle pain; 11 patients underwent hardware removal (18.6%), with 8 patients undergoing removal because of hardware-related pain (13.6%). FAOS scores (n = 51) were as follows: pain (79.9 ± 22.3), activities of daily living (84.2 ± 22.6), symptoms (75.7 ± 23.5), sports (69.4 ± 31.6), and quality of life (58.3 ± 30.5). Posterior and posterolateral plating achieved good clinical and high functional outcomes across our study population. The percentage of hardware removal in our study was either equivalent to, or less than, historical controls for any type of fibular fixation, and removal may be helpful for those patients whose postoperative ankle pain is subjectively related to the hardware.

Perceptions of mental illness etiology and treatment in Saudi Arabian healthcare students: A cross-sectional study
Authors: Alahmed Salman , Anjum Irfan , Masuadi Emad 
Published: July 2018

Objectives: Cultural beliefs often affect people’s attitude toward mental illness and their help-seeking behavior. Belief in superstitious causes of mental illness can lead to seeking help from non-medical practitioners, which might hinder treatment. This study aimed to explore the perception of mental illness and help-seeking behavior among healthcare students. Methods: A cross-sectional study carried out on a sample of 400 randomly selected undergraduate health professional students in Riyadh. Data collection involved two self-administered questionnaires: the causes and treatment routes for a female vignette with psychosis and the General Health Questionnaire-28. Results: The mean age of participants was 20.9 years, and 68.2% were male. Although participants reported a lack of personal history of mental illness (81.9%), female participants were more likely to disclose psychological distress as measured by General Health Questionnaire-28 (67.6%). Mental illness (47.2%) was chosen as the main reason for the problem depicted by the female vignette. General Health Questionnaire-28 scores for “caseness” did not affect perception about psychosis versus non-caseness. Factor analysis produced four dimensions for causes of psychosis: “social,” “psychobiological,” “superstitious,” and “socially undesirable”; and two treatment routes: “clinical” versus “social interventions.” Male participants leaned toward social factors for the cause of psychosis and were more likely to endorse social interventions for treatment. Conclusion: Healthcare students in Riyadh remained supportive of a biomedical approach toward the causation and treatment of mental illness. The use of religious practices as an adjunct was apparent. Students, especially females, were prone to experience more psychological distress.

BackgroundPerforation is the most serious complication of esophageal foreign bodies. Studies examining the association between diabetes and esophageal foreign body‐induced perforation are largely non‐existent.ObjectivesThe purpose of this study was to identify the risk factors for esophageal foreign body‐induced perforation.MethodsA retrospective chart review of patients with esophageal foreign bodies between January 2012–January 2017 was performed at the Chinese People's Liberation Army General Hospital. The patients were divided into two groups: those complicated with perforation and those without perforation. Date on patient demographics, symptoms, foreign bodies, and diabetes were collected and analyzed. Study‐specific odds ratio and 95% confidence intervals (CI) were estimated using multivariable logistic regression models.ResultsOf 294 patients with esophageal foreign bodies (41.84% male, mean age, 56.73 years), 33 (11.22%) complicated by perforation. Diabetes (odds ratio = 6.00; 95% confidence interval = 1.72–20.23), duration (>24 h) of foreign bodies retention (odds ratio = 4.25; 95% confidence interval = 1.71–10.86), and preoperative fever (odds ratio = 8.19; 95% confidence interval = 3.17–21.74) were strongly associated with an increased risk of perforation, whereas the sensation of a foreign body (odds ratio = 0.32; 95% confidence interval = 0.09–0.92) was a protective factor of perforation. Glucose level was not observed to have an association among patients with or without perforation.ConclusionsDiabetes and duration of foreign body retention increase risk for esophageal foreign bodies complicated by perforation, and cases with elevated armpit temperature may represented a more likely perforation compared with those without fever.
Asymptomatic Participants With a Femoroacetabular Deformity Demonstrate Stronger Hip Extensors and Greater Pelvis Mobility During the Deep Squat Task

Published: July 2018

Background: Cam-type femoroacetabular impingement (FAI) is a femoral head-neck deformity that causes abnormal contact between the femoral head and acetabular rim, leading to pain. However, some individuals with the deformity do not experience pain and are referred to as having a femoroacetabular deformity (FAD). To date, only a few studies have examined muscle activity in patients with FAI, which were limited to gait, isometric and isokinetic hip flexion, and extension tasks. Purpose: To compare (1) hip muscle strength during isometric contraction and (2) lower limb kinematics and muscle activity of patients with FAI and FAD participants with body mass index–matched healthy controls during a deep squat task. Study Design: Controlled laboratory study. Methods: Three groups of participants were recruited: 16 patients with FAI (14 male, 2 female; mean age, 38.5 ± 8.0 years), 18 participants with FAD (15 male, 3 female; mean age, 32.5 ± 7.1 years), and 18 control participants (16 male, 2 female; mean age, 32.8 ± 7.0 years). Participants were outfitted with electromyography electrodes on 6 muscles and reflective markers for motion capture. The participants completed maximal strength tests and performed 5 deep squat trials. Muscle activity and biomechanical variables were extrapolated and compared between the 3 groups using 1-way analysis of variance. Results: The FAD group was significantly stronger than the FAI and control groups during hip extension, and the FAD group had greater sagittal pelvic range of motion and could squat to a greater depth than the FAI group. The FAI group activated their hip extensors to a greater extent and for a longer period of time compared with the FAD group to achieve the squat task. Conclusion: The stronger hip extensors of the FAD group are associated with greater pelvic range of motion, allowing for greater posterior pelvic tilt, possibly reducing the risk of impingement while performing the squat, and resulting in a greater squat depth compared with those with symptomatic FAI. Clinical Relevance: The increased strength of the hip extensors in the FAD group allowed these participants to achieve greater pelvic mobility and a greater squat depth by preventing the painful impingement position. Improving hip extensor strength and pelvic mobility may affect symptoms for patients with FAI.

Abstract
Background
Squatting is a core exercise for many purposes. The tissue loading during squatting is crucial for positive adaptation and to avoid injury. This study aimed to evaluate the effect of narrow, hip and wide stance widths, foot position angles (0°, 21°, and 42°), strength exercise experience, and barbell load (0 and 50% body weight, experts only) during squatting.

Methods
Novice (N = 21) and experienced (N = 21) squatters performed 9 different variations of squats (3 stance widths, 3 foot placement angles). A 3D motion capture system (100 Hz) and two force plates (2000 Hz) were used to record mediolateral knee displacement (ΔD*), range of motion (RoM) at the hip and knee joints, and joint moments at the hip, knee, and lower back.

Results
Both stance width and foot placement angles affected the moments at the hip and knee joints in the frontal and sagittal planes. ΔD* varied with stance width, foot placement angles and between the subjects’ level of experience with the squat exercise as follows: increasing foot angle led to an increased foot angle led to an increased ΔD*, while an increased stance width resulted in a decreased ΔD*; novice squatters showed a higher ΔD*, while additional weight triggered a decreased ΔD*.

Conclusions
Suitable stance width and foot placement angles should be chosen according to the targeted joint moments. In order to avoid injury, special care should be taken in extreme positions (narrow stand-42° and wide stance-0°) where large knee and hips joint moments were observed.
