Relationships Between Lateral Limb Bias, Turnout, and Lower Limb Injury in a Female Pre‑Professional Ballet Dancer Population

J Dance Med Sci. 2021 Mar 29. doi: 10.12678/1089-313X.061521i. Online ahead of print.

ABSTRACT

Dancers are known to have specific limb preferences when they dance and commonly experience lower limb injury, especially early in their training. The primary aim of this study was to determine and examine the relationships between lateral limb bias, perceived turnout profile, and lower limb injury history in female pre-professional ballet dancers using current definitions of lateral bias, leg dominance, and the concept of “working” and “supporting” legs in dance. A cross-sectional survey design with retrospective recall of 12-month injury history was employed. An online questionnaire was distributed to female dancers between the ages of 16 and 21 years who were training in classical ballet at the pre-professional level in Australia. The questionnaire gathered information regarding laterality, perceived turnout asymmetry, and self-reported 12-month injury profile. Descriptive and correlation analyses were employed to describe dancer profiles and determine relationships between the three variables. Thirty-two dancers participated. The majority of participants (67%) had right-side dominance and most indicated the right leg as their preferred supporting leg (86.7%) and working leg (60%). A total of 17 participants (53.1%) reported at least one injury in the preceding 12-month period and the side injured was significantly correlated with leg dominance (rS = 0.595, p = 0.012), with the majority of injuries also affecting the preferred supporting and working leg. Dancer perceptions regarding turnout range were correlated with their perceptions of leg dominance (rS = 0.556, p = 0.001), but no statistically significant associations were found between perceptions of turnout range and injury side. In pre-professional dancers, the dominant and the preferred supporting or working leg tend to be the same leg, and the results suggest that the dominant and preferred supporting and working leg of dancers are at greatest risk of injury.

Is Matching Exercise Intensity to Heart Rate Variability a Key to Effective Conditioning for Dancers? A Prospective Randomized Controlled Trial

J Dance Med Sci. 2021 Mar 29. doi: 10.12678/1089-313X.061521d. Online ahead of print.

ABSTRACT

Dancers seek studio-based conditioning methods that improve fitness to help them meet the demands of their discipline. Heart rate variability (HRV) mobile technology offers one such potential method. The purpose of this prospective randomized controlled trial was to investigate how HRV impacted fitness outcomes over a 4 to 6 week period of supplemental training. The study’s cohort, 134 competitive female dancers ages 12 to 35, were randomly assigned to one of three groups: the HRV study group, the Tabata high-intensity control group, or the Vinyasa yoga low-intensity control group. Fitness assessments conducted in the pre- and post-training period included cardiovascular endurance, muscular endurance, and lower extremity power. These assessments were evaluated with ANOVA between group and within group comparisons. Results revealed lower extremity power improvement in the HRV group at a statistically significant level (p < 0.05) and overall trends toward greater muscle endurance. Additional unanticipated findings surfaced in the yoga control group that demonstrated cardiovascular improvements and normalization of right versus left lower extremity power discrepancies. Conclusions support the use of HRV mobile technology to individualize daily conditioning intensity, thereby efficiently improving lower extremity power and overall muscle endurance for dancers while monitoring for signs of overtraining.

There is no dose-response relationship between allogeneic blood transfusion and healthcare-associated infection: a retrospective cohort study

Antimicrob Resist Infect Control. 2021 Mar 29;10(1):62. doi: 10.1186/s13756-021-00928-5.

ABSTRACT

BACKGROUND: The association between allogeneic blood transfusion and healthcare-associated infection (HAI) is considered dose-dependent. However, this association may be confounded by transfusion duration, as prolonged hospitalization stay increases the risk of HAI. Also, it is not clear whether specific blood products have different dose-response risks.

METHODS: In this retrospective cohort study, a logistic regression was used to identify confounding factors, and the association between specific blood products and HAI were analyzed. Then Cox regression and restricted cubic spline regression was used to visualize the hazard of HAI per transfusion product.

RESULTS: Of 215,338 inpatients observed, 4.16% were transfused with a single component blood product. With regard to these transfused patients, 480 patients (5.36%) developed a HAI during their hospitalization stay. Logistic regression showed that red blood cells (RBCs) transfusion, platelets transfusion and fresh-frozen plasmas (FFPs) transfusion were risk factors for HAI [odds ratio (OR) 1.893, 95% confidence interval (CI) 1.656-2.163; OR 8.903, 95% CI 6.646-11.926 and OR 1.494, 95% CI 1.146-1.949, respectively]. However, restricted cubic spline regression analysis showed that there was no statistically dose-response relationship between different transfusion products and the onset of HAI.

CONCLUSIONS: RBCs transfusion, platelets transfusion and FFPs transfusion were associated with HAI, but there was no dose-response relationship between them.

Validation of a second-generation appropriateness classification system for total knee arthroplasty: a prospective cohort study

J Orthop Surg Res. 2021 Mar 29;16(1):227. doi: 10.1186/s13018-021-02371-z.

ABSTRACT

BACKGROUND: To test the validity of a second-generation appropriateness system in a cohort of patients undergoing total knee arthroplasty (TKA).

METHODS: We applied the RAND/UCLA Appropriateness Method to derive our second-generation system and conducted a prospective study of patients diagnosed with knee osteoarthritis in eight public hospitals in Spain. Main outcome questionnaires were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Short-Form-12 (SF-12), and the Knee Society Score satisfaction scale (KSS), completed before and 6 months after TKA. Baseline, changes from baseline to 6 months (journey outcome), and 6-month scores (destination outcome) were compared according to appropriateness category. Percentage of patients attaining the minimal clinically important difference (MCID) and responders according to Outcome Measures in Rheumatology-Osteoarthritis Research Society (OMERACT-OARSI) criteria were also reported.

RESULTS: A total of 282 patients completed baseline and 6-month questionnaires. Of these, 142 (50.4%) were classified as Appropriate, 90 (31.9%) as Uncertain, and 50 (17.7%) as Inappropriate. Patients classified as Appropriate had worse preoperative pain, function, and satisfaction (p < 0.001) and had greater improvements (i.e., journey scores) than those classified as Inappropriate (p < 0.001). At 6 months, destination scores for pain, function, or satisfaction were not significantly different across appropriateness categories. The percentage of patients meeting responder criteria (p < 0.001) and attaining MCID was statistically higher in Appropriate versus Inappropriate groups in pain (p = 0.04) and function (p = 0.004).

CONCLUSIONS: The validity of our second-generation appropriateness system was generally supported. The findings highlight a critical issue in TKA healthcare: whether TKA appropriateness should be driven by the extent of improvement, by patient final state, or by both.

Determining risk factors of continuous renal replacement treatment after emergency surgery for type A acute aortic dissection: statistical issues

J Cardiothorac Surg. 2021 Mar 29;16(1):59. doi: 10.1186/s13019-021-01396-z.

ABSTRACT

This letter to the editor has made several comments regarding possible statistical issues in recent article by Wang et al. determining the risk factors of continuous renal replacement treatment after emergency surgery for type A acute aortic dissection, which is published in Journal of Cardiothoracic Surgery. 2020; 15(1):100. Our comments were involved in the issues of using the propensity score matched cohorts to adjust the covariates that can potentially confound the primary outcomes, process of establishing multivariate model and application of Kaplan-Meier curve analysis in this retrospective study. We would like to remind readers to pay special attention to these issues and invite the authors to comment on these.

Protocol for a quasi-experimental, 950 county study examining implementation outcomes and mechanisms of Stepping Up, a national policy effort to improve mental health and substance use services for justice-involved individuals

Implement Sci. 2021 Mar 29;16(1):31. doi: 10.1186/s13012-021-01095-2.

ABSTRACT

BACKGROUND: The criminal justice system is the largest provider of mental health services in the USA. Many jurisdictions are interested in reducing the use of the justice system for mental health problems. The national Stepping Up Initiative helps agencies within counties work together more effectively to reduce the number of individuals with mental illness in jails and to improve access to mental health services in the community. This study will compare Stepping Up counties to matched comparison counties over time to (1) examine the effectiveness of Stepping Up and (2) test hypothesized implementation mechanisms to inform multi-agency implementation efforts more broadly.

METHODS: The study will survey 950 counties at baseline, 18 months, and 36 months in a quasi-experimental design comparing implementation mechanisms and outcomes between 475 Stepping Up counties and 475 matched comparison counties. Surveys will be sent to up to four respondents per county including administrators of jail, probation, community mental health services, and community substance use treatment services (3800 total respondents). We will examine whether Stepping Up counties show faster improvements in implementation outcomes (number of justice-involved clients receiving behavioral health services, number of behavioral health evidence-based practices and policies [EBPPs] available to justice-involved individuals, and resources for behavioral health EBPP for justice-involved individuals) than do matched comparison counties. We will also evaluate whether engagement of hypothesized mechanisms explains differences in implementation outcomes. Implementation target mechanisms include (1) use of and capacity for performance monitoring, (2) use and functioning of interagency teams, (3) common goals and mission across agencies, and (4) system integration (i.e., building an integrated system of care rather than adding one program or training). Finally, we will characterize implementation processes and critical incidents using survey responses and qualitative interviews.

DISCUSSION: There are few rigorous, prospective studies examining implementation mechanisms and their relationship with behavioral health implementation outcomes in justice and associated community behavioral health settings. There is also limited understanding of implementation mechanisms that occur across systems with multiple goals. This study will describe implementation outcomes of Stepping Up and will elucidate target mechanisms that are effective in multi-goal, multi-agency systems.

Effect of short-term and long-term traffic noise exposure on the thyroid gland in adult rats: a sexual dimorphic study

Horm Mol Biol Clin Investig. 2020 Dec 14;42(1):29-35. doi: 10.1515/hmbci-2020-0029.

ABSTRACT

OBJECTIVES: Traffic noise, as one of the noise types, is a widespread feature of the urban environments. Traffic noise exposure can lead to hearing loss, hypertension, obesity and ischemic heart diseases. Thyroid hormones involved in the physiological and pathological conditions of the body. Therefore, this study was designed to aim the evaluation of traffic noise effects on thyroid hormones secretion and thyroid tissue structure.

METHODS: Seventy two males and females wistar rats were used in this study. After one week adaptation, they divided randomly into 12 groups; the control, short term (one day) and long term (one, two, three and four weeks) groups. Traffic sound was recorded, adjusted and played (86 dB) for animals. Female rats’ cycle estrus was matched. At the end of experiment, the animals were anesthetized and cardiac blood sample was drawn. Thyroid tissue was then removed. Levels of the T3, T4, TSH, corticosterone and H&E staining were measured. p<0.05 considered to be statistically significant.

RESULTS: Findings showed that in the one-day group, T3 levels increased and T3 levels decreased in the long term groups (p<0.05). In the same way, concentration of TSH decreased in the one day, while they increased in the one, two, three and four weeks’ groups (p<0.05). Histopathological evaluations showed that in the female and male animals, long-term traffic noise increased the full follicles and decreased empty follicles (p<0.05).

CONCLUSIONS: This study revealed that traffic noise exposure led to increase of T3 plasma concentration and decrement of TSH level, although in the long term, they return to basal status. It may be due to adaptation to traffic noise.

Effect of aromatherapy massage with orange essential oil on postoperative pain after cesarean section: a randomized controlled trial

J Complement Integr Med. 2021 Mar 29. doi: 10.1515/jcim-2020-0138. Online ahead of print.

ABSTRACT

OBJECTIVES: Many women in recent years have been willing to undergo puncture surgery for childbirth, which, like other surgeries, has physical and psychological side effects such as incision, infertility, chronic pain, and anxiety. Therefore, it is important to reduce and improve these side effects. The aim of this study was to determine the effect of foot massage with orange essential oil on pain and anxiety in women undergoing cesarean section.

METHODS: This randomized clinical trial study was conducted in 2019 on 80 women referred to Bahar Shahroud Hospital after cesarean section surgery. The samples were divided into two groups by intervention (foot massage with orange essential oil) and control (foot massage without orange essential oil). The Spielberger scale was used to determine anxiety scores after cesarean section. In the intervention group, the feet were massaged with orange essential oil, and in the control group, the orange essential oil massage was performed without oil. Anxiety before, immediately after, and 60 min after the intervention was measured and evaluated in both groups. Data analysis was performed using descriptive and inferential statistics. Significant levels were considered for all statistical tests (p<0.05).

RESULTS: The anxiety score before the intervention in the two groups of intervention and control was 57.12 ± 3.12 and 57.07 ± 3.54, respectively, which were not significantly different, but immediately after the intervention, the anxiety scores in both groups decreased significantly so that there was a further decrease in the intervention group (52.10 ± 4.75 and 56.02 ± 3.77), 1 h after the intervention, the anxiety score in the intervention group decreased compared to the previous stage and increased in the control group (50.40 ± 3.74 and 56.85 ± 4.27).

CONCLUSIONS: Foot massage with orange essential oil can probably be effective as a proper nursing intervention in reducing anxiety after cesarean section surgery.

Safety and Efficacy of High-Powered Holmium Laser Enucleation of the Prostate within 1-3 Weeks Following Prostate Biopsy

Urol Int. 2021 Mar 29:1-6. doi: 10.1159/000514422. Online ahead of print.

ABSTRACT

PURPOSE: We aim to document the feasibility, perioperative safety, and the 12-month efficacy of holmium laser enucleation of the prostate (HoLEP) within 1-3 weeks following transrectal ultrasound (TRUS)-guided prostate biopsy.

METHODS: Data of the patients who underwent HoLEP following TRUS-guided prostate biopsy between March 2017 and July 2020 were analyzed retrospectively. Patients were divided into 2 groups: group 1 had undergone HoLEP in the early period after TRUS-guided prostate biopsy, while group 2 patients were biopsy-naive (“control group”). All patients were assessed preoperatively by a physical examination with the digital rectal examination; time from biopsy to HoLEP; measurement of Qmax, postvoiding residual volume, and prostate volume by transabdominal ultrasonography; serum prostate-specific antigen level, the International Prostate Symptom Score (IPSS); the International Index of Erectile Function-5 questionnaire; and urine analysis. The patients were reevaluated at 3- and 12-month follow-up. Perioperative and postoperative complications were documented according to the modified Clavien-Dindo System.

RESULTS: Group 1 comprised 66 patients with a mean age of 67.3 ± 6.7 (range, 53-86) years, and group 2 comprised 114 patients with a mean age of 69.4 ± 9.4 (range, 36-95) years. The operation, enucleation, and morcellation efficiencies were not statistically significant between the groups. Preoperative Qmax and IPSS values were significantly improved after HoLEP surgery in the 3rd and 12th months in all patients. Our complication rates were similar in both groups.

CONCLUSION: High-powered HoLEP using 140 W energy within 1-3 weeks following TRUS-guided prostate biopsy is a feasible procedure with high enucleation efficiency, low perioperative morbidity, and excellent functional outcomes. A recent TRUS-guided prostate biopsy is not a contraindication to HoLEP.
