Authors: Helenius Linda L. , Oksanen Hanna , Lastikka Markus , Pajulo Olli , Löyttyniemi Eliisa , Manner Tuula , Helenius Ilkka J.
Published: November 2019

Background:

Pregabalin as part of a multimodal pain-management regimen has been shown to reduce opioid consumption after spinal surgery in adults but it is unclear whether this is also true in adolescents. Pregabalin has been found to have neuroprotective effects and therefore could have a positive impact on pain after spinal deformity surgery. We conducted a randomized, double-blinded, placebo-controlled clinical trial of adolescent patients undergoing spinal fusion to evaluate the short-term effects of pregabalin on postoperative pain and opioid consumption.

Methods:

Adolescents with adolescent idiopathic scoliosis, Scheuermann kyphosis, or spondylolisthesis who were scheduled for posterior spinal fusion with all-pedicle-screw instrumentation were randomized to receive either pregabalin (2 mg/kg twice daily) or placebo preoperatively and for 5 days after surgery. The patients ranged from 10 to 21 years of age. The primary outcome was total opioid consumption as measured with use of patient-controlled analgesia. Postoperative pain scores and opioid-related adverse effects were evaluated.

Results:

Sixty-three of 77 eligible patients were included and analyzed. Cumulative oxycodone consumption per kilogram did not differ between the study groups during the first 48 hours postoperatively, with a median of 1.44 mg/kg (95% confidence interval [CI],1.32 to 1.67 mg/kg) in the pregabalin group and 1.50 mg/kg (95% CI, 1.39 to 1.79 mg/kg) in the placebo group (p = 0.433). A subgroup analysis of 51 patients with adolescent idiopathic scoliosis showed the same result, with a mean of 1.45 mg/kg (95% CI, 1.24 to 1.65 mg/kg) in the pregabalin group and 1.59 mg/kg (95% CI, 1.37 to 1.82 mg/kg) in the placebo group (p = 0.289). Total oxycodone consumption per hour (mg/kg/hr) was not different between the groups over the time points (p = 0.752). The postoperative pain scores did not differ significantly between the groups (p = 0.196).

Conclusions:

The use of perioperative pregabalin does not reduce the postoperative opioid consumption or pain scores in adolescents after posterior spinal fusion surgery.

Online Direct-to-Consumer Advertising of Stem Cell Therapy for Musculoskeletal Injury and Disease
Authors: Kingery Matthew T. , Schoof Lauren , Strauss Eric J. , Bosco Joseph A. , Halbrecht Joanne
Published: November 2019

Background:

There has been a recent surge in health-care providers offering stem cell therapy (SCT) to patients with musculoskeletal disease. The purpose of this study was to identify and quantify the misinformation present in online direct-to-consumer (DTC) advertising of SCT targeting patients with musculoskeletal disease in the U.S. It was hypothesized that DTC advertising of SCT contains substantial misinformation.

Methods:

A list of keywords was used to identify web sites of practices advertising SCT directly to patients with musculoskeletal disease. Web sites were evaluated to determine the specialties of providers offering SCT, types of SCT being advertised, and misinformation presented. Categories of misinformation included false general claims, inaccurate statements regarding mechanism of action, unfounded results, and scare tactics.

Results:

Of the 896 practice web sites included in the analysis, 95.9% contained at least 1 statement of misinformation, with a mean of 4.65 ± 3.66 statements of misinformation among the sites. Practices associated with an orthopaedic surgeon provided 22% fewer statements of misinformation than practices without an orthopaedic surgeon when we controlled for the effects of other specialties. Practices associated with a podiatrist also provided 22% fewer statements of misinformation.

Conclusions:

Nearly all practices failed to accurately represent the clinical efficacy of SCT in DTC advertising. While practices associated with an orthopaedic surgeon were less likely to provide misinformation, the majority of all web sites contained some type of misinformation, ranging from errors in the basic science of stem cells to outright false and misleading claims of their clinical effectiveness.
Subscapularis-Sparing Rotator Interval Approach for Anatomic Total Shoulder Arthroplasty
Authors: Adkison David P. , Hudson Parke W. , Worthen James V. , Moon Andrew S. , Pinto Martim C. , Momaya Amit , Ponce Brent A. , Brabston Eugene W.
Published: November 2019

Background:

A subscapularis-sparing approach to anatomic total shoulder arthroplasty (TSA) is used for patients with glenohumeral osteoarthritis who have an intact rotator cuff and sufficient bone volume.

Description:

A 7 to 10-cm anterosuperior incision is made with the patient in the beach chair position. The anterolateral deltoid muscle raphe is split, and the shoulder is externally rotated to bring the rotator interval to the field. A flap of interval tissue is incised, tenodesis of the biceps tendon is performed, and the interval tissue is incised straight back to the glenoid from the upper edge of the subscapularis, creating a triangular piece of tissue referred to as a “trapdoor.” Two Darrach retractors are placed to expose the humeral head. An intramedullary guide is placed, and a humeral head osteotomy is performed. The glenoid is exposed, and the glenoid component is placed after sizing, preparation, drilling, and insertion of trial components per the surgical technique. The humeral head size is estimated by measuring, and the humeral stem size is decided by sequentially inserting the trial components. The permanent humeral stem is inserted, and the permanent humeral head is implanted after insertion of trial components. The trapdoor is sutured, the deltoid is reattached, and subcutaneous tissue and skin are sutured.

Alternatives:

The traditional surgical approach for anatomic TSA involves release and reattachment of the subscapularis tendon.

Rationale:

Nearly all anatomic TSA techniques require the subscapularis to be released, with a peel, tenotomy, or osteotomy, and then repaired on completion of the arthroplasty. Failure of the subscapularis to heal is an unfortunate and potentially devastating complication following anatomic TSA that has been linked to decreased function, instability, and pain
1–4
. Subscapularis dysfunction following anatomic TSA is seen in one-third to two-thirds of patients, with evidence of complete tears in up to 50% of asymptomatic patients using ultrasound examinations
1–5
.

Sling immobilization with avoidance of excessive passive external rotation and active internal rotation is recommended to help prevent postoperative rupture of the subscapularis repair
6–8
. However, postoperative motion restrictions to protect the subscapularis may lead to stiffness and may negatively impact function and satisfaction.

We describe a subscapularis-sparing TSA, in which we address and improve on 3 technical difficulties identified by Lafosse et al.
9
: (1) difficulty ensuring an anatomic humeral neck cut because of the difficulty visualizing the anterior aspect of the shoulder, (2) inadequate resection of inferior humeral neck osteophytes, and (3) undersizing of the humeral head.

Published: November 2019

Background: One of the option for treating unicompartmental osteoarthritis (OA) is high tibial osteotomy (HTO). HTO which can shift the mechanical axis to the lateral compartment, can performed with microfracture which provides cells capable of producing cartilage. And this procedure is one of the common combinations that orthopaedic surgeons are in practice recently. The purpose of this study was to evaluate the degree of regeneration of cartilage after performing microfracture (MF) with high tibial osteotomy (HTO) after 2- year follow up and identify the factors influencing the regeneration of cartilage after the procedure. We also evaluated whether the regenerated cartilage status affects clinical outcomes. Methods: A total of 81 cases that underwent second-look arthroscopy at the time of plate removal after MF and HTO with a minimum two-year follow-up were included. The patients were divided into two groups according to femoral cartilage regeneration. Multivariable logistic regression analyses were performend to identify independent factors that influence cartilage regeneration. We also compared differences in functional outcomes between the two groups. Results: On the femoral side, grade I cartilage regeneration was found in seven (8.6%), grade II in 19 (23.5%), grade III in 26 (32.1%), and grade IV in 29 cases (35.8%), resulting in 26 (32.1%) patients belonging to well regenerated group (group A) and 55 (67.9%) to the poorly regenerated group (group B). Among factors, the size of the cartilage lesion (P=.011) and the presence of kissing lesions (P=.027) significantly affected cartilage regeneration. There were no statistically significant differences between group A and group B in terms of KSS and WOMAC scores. Conclusions: A large cartilage defect and the presence of kissing lesions are associated with poor cartilage regeneration after combined MF and HTO surgery. However, the quality of regenerated cartilage does not affect functional outcomes in patients with MF and HTO.

Different forms of informal coercion in psychiatry – a qualitative study
Authors: Pelto-Piri Veikko , Kjellin Lars , Hylén Ulrika , Valenti Emanuele , Priebe Stefan
Published: November 2019

Objectives
The objective of the study was to investigate how mental health professionals describe and reflect upon different forms of informal coercion.
Results
In a deductive qualitative content analysis of focus group interviews, several examples of persuasion, interpersonal leverage, inducements, and threats were found. Persuasion was sometimes described as being more like a negotiation. Some participants worried about that the use of interpersonal leverage and inducements risked to pass into blackmail in some situations. In a following inductive analysis, three more categories of informal coercion was found: cheating, using a disciplinary style and referring to rules and routines. Participants also described situations of coercion from other stakeholders: relatives and other authorities than psychiatry.
The results indicate that informal coercion includes forms that are not obviously arranged in a hierarchy, and that its use is complex with a variety of pathways between different forms before treatment is accepted by the patient or compulsion is imposed.

Background: Lifestyle factors such as body mass index (BMI), alcohol drinking, and cigarette smoking, are likely to profoundly impact the prognosis of gastric cancer, but evidence has been inconsistent. Methods: Patients with gastric cancer were identified from the China National Cancer Center Gastric Cancer Database (NCCGCDB) 1998-2018. Survival analysis performed via Kaplan-Meier estimates and Cox proportional hazards models. Results: In this study, we reviewed 18 441 cases of gastric cancer patients. Individuals who were overweight or obese was associated with positive smoking and drinking history (P=0.002 and P<0.001, respectively). Current smokers are more likely to be current alcohol drinkers (61.3% vs.10.1% vs. 43.2% for current, never, and former smokers, respectively, P<0.001). Multivariable results indicated that BMI at diagnosis had no significant effect on prognosis. In gastrectomy patients, factors independently associated with poor survival include older age (HR=1.20, 95% CI: 1.05-1.38, P=0.001), any weight loss (P<0.001), smoking history more than 30 years (HR=1.14, 95% CI: 1.04-1.24, P=0.004), and increasing pTNM stage (P<0.001). Conclusion: In conclusion, this study of gastric cancer patients has examined the association of lifestyle factors above with long-term prognosis. Among the patients overall, weight loss (both 0-10% and >10% groups), but not BMI values at diagnosis, was related to survival results. For other factors, smoking history of more than 30 years conferred a worse prognosis for only gastrectomy patients. Extensive efforts are needed to elucidate mechanisms targeting the complex effects of lifestyles factors.

Background, Since 1990, life expectancy and nonagenarian ratio in South China have been higher than those in North China.
Methods, To determine the reason residents of South China live longer, we calculated age-specific mortality rates (per 100,000 people) in North and South China. We examined the associations between the provincial mortality rates due to major fatal diseases and life span indicator.
Results, CVD is the leading cause of death in China. The proportion of CVD in all-cause mortality increases with age, and its mortality rate accounts for over 50% of all-cause mortalities in people aged over 80 years. Moreover, the mortality rate of CVD gradually decreases from north to south, indicating the main reason of difference in longevity between North and South China. This difference can be attributed to variations in temperature, salt consumption, selenium intake, air pollution, overweight and obesity between the two regions. Lower mortality rates of individuals aged 55–89 years in South China lead to higher longevity level. Provincial gravity centers of the proportion of longevity population move southward, and this shift is accelerated with increasing age.
Conclusions, the mortality rate of CVD gradually decreases from north to south is the reason residents of South China live longer, and risk factors of CVD gradually decreases from north to south.

Background: To compare the changes in the anterior segment after femtosecond laser in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) using a dual rotating Scheimpflug (DRS) analyzer (Galilei®; Ziemer Ophthalmology, Port, Switzerland).Methods: A total of 218 eyes of 109 patients who underwent FS-LASIK or SMILE for myopic correction were retrospectively studied. Ninety-eight eyes of 49 patients who underwent FS-LASIK were compared to 120 eyes of 60 patients treated with SMILE. A DRS analyzer was used for preoperative and 6-month postoperative anterior segment analyses. Measured variables included the central corneal thickness (CCT), anterior chamber depth (ACD), anterior and posterior keratometry (K), anterior and posterior best-fit sphere radius, and maximum posterior elevation (MPE).Results: After the procedure, the amount of CCT decrease was higher in the SMILE group than in the FS-LASIK group, but it was not statistically significant. The MPE was significantly increased after both procedures (p < 0.001 and p = 0.001 in the FS-LASIK and SMILE groups, respectively), with the amount of elevation being higher after FS-LASIK than after SMILE even though it was not statistically significant. And there was a significant change in the steep and average posterior K in the FS-LASIK group (p = 0.006 and 0.001, respectively), but not in the SMILE group.Conclusions: Regarding changes in the MPE and posterior K, changes in the posterior corneal surface were greater after FS-LASIK than after SMILE.

DETERMINATION OF THE GEOMETRIC SIZE OF THE COMMUNICATION HOLE OF TWO CYLINDRICAL WAVEGUIDES

Published: November 2019

It is always relevant to improve performance in electrodynamic systems. When solving problems on the electrodynamic characteristics of hollow coupled systems, the question is often asked about the relationship between them, about the form of the communication hole with a certain orientation of the guide axes in the system elements and its geometric dimensions. Such a system is a generator (small-sized local oscillator8 mmrange). The inclusion of a high-Q stabilizing resonator in the Gunn diode generator significantly improves its characteristics. The use of a low-quality coaxial chamber as a diode section increases the generation stability. However, this complicates the numerical calculations of the electrodynamic system of the generator due to the uncertain configuration of the communication hole, since it arises as a result of the intersection of two cylindrical volumes of a coaxial waveguide and a high-quality cylindrical resonator. In the present work, the task is determination of the shape and size of the intersection figure of two unequal radii of cylindrical volumes with axes orthogonally located in relation to each other at a distance. The resulting shape of the intersection figure in a planar approximation forms a flat ellipse. The larger diameter of the coupling ellipse depends on the diameter of the resonator, the smaller on the inner diameter of the coaxial chamber, depending on the distance between their axes. It is necessary to determine the equivalent rectangular hole of the connection. Its presence simplifies the construction of a tangent electric field at the communication hole, which is necessary for numerical calculations of the electrodynamic characteristics of the system. In this case, with constant diameters of the cylindrical resonators, the geometrical dimensions of the hole depend only on the distance between the axes. It is with this circumstance that they are dealing with the study of the connection between a cylindrical coaxial diode section and a high-Q stabilizing resonator. Unlike other circuits, where the diode is included in the waveguide section, in this case, its inclusion is made in a coaxial line.
The influence of U.S. equity returns on Asian-Pacific equity markets
Authors: D. Benson Earl , X. Kong Sophie
Published: November 2019

This paper examines monthly and daily returns in eleven Asian-Pacific equity markets and the U.S. market, showing that the Asian-Pacific markets systematically follow the returns in the U.S. market (S&P 500 index). For investment managers, the important findings include the fact that each Asian-Pacific market moves differently in response to U.S. market changes over a given time period and the response of most of these markets to changes in the U.S. market is not stable over time. Therefore, in their attempt to diversify a portfolio using individual Asian-Pacific country equities, past correlations and covariances are not necessarily a good predictor of future values, especially for the less developed countries. On average, more developed markets react more strongly to U.S. market changes than do the less developed markets. All markets exhibit asymmetries relative to the U.S. market, where reactions are stronger following down-days than following up-days. Finally, the tests suggest that the Asian-Pacific markets have little or no influence on U.S. market returns.

Published: November 2019

This paper investigated factors influencing students’ pronunciation. Pronunciation is one of the important aspects of the learning of English. When mastering English pronunciation, many non-native English speakers have difficulty pronouncing certain words that contain the phonemes not used in their native languages. This paper also reported several aspects that might influence pronunciation. The pronunciation aspect investigated in this research paper was the English interdental consonants [θ] and [ð], which are not available in the Indonesian language sound system. This qualitative research used interviews as a method for collecting primary data. The researchers interviewed twenty participants from the English Language Education Study Program (ELESP) of Sanata Dharma University, Yogyakarta, Indonesia, related to the pronunciation of the two interdental consonant sounds. The findings showed that the mother tongue, age, and teacher instruction on target language exposures affected the ELESP students’ (mis)pronunciation. Pedagogical implications of the findings are English teachers can assist their students in overcoming pronunciation challenges involving the two interdental consonants and pronunciation textbook writers should  provide more  pronunciation practices focusing on [θ] and [ð] sounds.
