RESUMO

Delayed-onset muscle soreness (DOMS) is associated with increases in acute inflammatory and biochemical markers, muscle swelling, pain, and reduced functional performance. This study aimed to investigate the preventative effects of crocodile blood supplementation on DOMS induced by eccentric exercise. Sixteen healthy males were randomly allocated to either a crocodile blood (CB, n = 8) or a placebo (PL, n = 8) treatment. Participants receiving the CB treatment consumed four capsules of freeze-dried CB powder (1 g day-1) over 18 days. Participants receiving the other treatment were administered a placebo over the same period. An eccentric exercise protocol was performed, and functional performance, visual analogue scale (VAS)-measured pain, knee range of movement (ROM), thigh circumference (swelling), and cytokines, enzymes, and biochemical parameters were assessed immediately after exercise as well as after 24 h, 48 h, and 72 h. CB supplementation could significantly maintain maximum voluntary isometric contraction (MVIC) at 24 h (p = 0.001) and 48 h after exercise (p = 0.001) when comparing values at different times for the CB group. In the CB group, thigh circumference decreased only immediately after eccentric exercise (p = 0.031) in comparison with pre-eccentric exercise values. An 18-day supplementation (1 g day-1) of crocodile blood does aid in the maintenance of functional performance and muscle swelling after eccentric exercise. Our data indicate that 1 g day-1 of crocodile blood supplementation should be safe for human consumption.

RESUMO

Background: Despite its high risk of injury, many people are still favor trampolining. However, currently there is no consensus as to which type of trampoline and which type of participant is more likely to have a trampoline related injury that will require surgical management. Methods: This systematic review and meta-analysis aims to assess and compare the factors that cause trampoline injuries requiring surgical treatment. These include the place of the trampoline (park versus home), size of the trampoline (full versus mini), the age of the participant (child versus adult) and the sex of the participant (male versus female). The clinical outcomes measured are surgical management after trampoline injury. This systematic review was conducted according to the PRISMA guidelines. Results: Relevant studies that reported surgery after trampoline injury of either group were identified from Medline and Scopus from inception to May 14, 2019. Sixteen studies were included for the analysis of surgery after trampoline injury; a total of 4491 and 1121 patients were treated conservatively and surgically. The total surgery rate per patient was 31% (95% CI: 16, 46%) in all patients. The surgery rate was 0.3 (95% CI: 0.03, 0.58) and 0.06 (95% CI: 0.04, 0.09) in the full and mini size trampoline groups. There were 0.36 (95% CI: 0.06, 0.67) and 0.11 (95% CI: 0.0, 0.22) in the park and home trampoline groups. The surgery rates were 0.33 (95% CI: 0.14, 0.53), 0.24 (95% CI: 0.07, 0.11), 0.49 (95% CI: 0.47, 0.51) and 0.38 (95% CI: 0.22, 0.53) in children, adults, females and males respectively. Indirect meta-analysis shows that full size trampolines provided a 6.0 times higher risk of surgery (95% CI: 3.7, 9.7) when compared to mini size trampolines. Park trampolines had a higher risk of surgery of 2.17 (95% CI: 1.70, 2.78) when compared to home trampolines. In terms of age and sex of participants, there value was significantly higher at 1.65 (95% CI: 1.35, 2.01) and 1.54 (95% CI: 1.36, 1.74) in children compared to adults and females compared to males. From all the statistical data we summarized that the full size trampoline injuries have a 6 times higher risk of requiring surgery when compared to mini size trampoline injuries. Park trampoline use carries a 2 times higher risk of requiring surgery when compared to home trampoline use. In terms of age and sex of the participant, there is a 1.5 times significantly higher risk of injury in children compared to adults, and females when compared to males. Conclusion: In trampoline related injuries, full size, park trampoline, children and females had higher surgery rates when compared to mini size, home trampoline, adult and male majority in indirect meta-analysis methods.

RESUMO

BACKGROUND: A common complication of rotator cuff (RC) repair is a postoperative stiffness. Postoperative stiffness may develop and lead to inferior functional outcomes. Rotator cuff repair with additional rotator interval (RI) capsular release can be done to prevent postoperative stiffness in rotator cuff tears. However, routine rotator interval capsular release in rotator cuff repair is controversial. Therefore, we conducted a systematic review and meta-analysis to compare the postoperative outcomes between RC repair with and without RI capsular release for RC tears with and without concomitant stiffness. METHOD: We searched all comparative studies that compared postoperative outcomes (VAS, CS, ASES, complications and ROM at 3, 6 and 12 months) of RC repair with and without RI capsular release for RC tears with and without concomitant stiffness from PubMed and Scopus databases from inception to the February 1, 2020. RESULTS: Seven of 255 studies (six comparative studies and one RCT) (N = 803 patients) were eligible; 2 and 5 studies were included in the pooling of RC repair and RI release without concomitant stiffness and stiffness, respectively; 2, 6, 3, 6, 3, 5, 7, 7, and 7 studies were included in pooling of VAS, CS, ASES at 6 and 12 months and range of motion (internal, external rotation and forward flexion) at 3, 6 and 12 months, respectively. The UMD of VAS, CS and ASES scores at 6- and 12-month follow-up for the RC repair and RI release group was 0.48 (95% CI: 0.05, 0.90), 0.93 (-1.70, 3.56), -2.27 (-5.30, 0.76), -0.04 (-0.24, 0.15), 1.66 (0.77, 2.55) and 1.58 (0.21, 2.96) scores when compared to RC repair alone with and without concomitant stiffness. In terms of ROM, forward flexion for the RC repair and RI release group was -4.60 (-10.61, 1.41), -7.11 (-15.47, 1.25) and -0.70 (-2.51, -1.11) degrees at 3, 6 and 12 months, respectively, when compared to RC repair alone. For external rotation, RC repair and RI release were -0.12 (-8.27, 8.03), -3.98 (-12.09, 4.14) and -2.65 (-5.35, 0.04) degrees at 3, 6 and 12 months, respectively, when compared to RC repair alone. For internal rotation in RC repair and RI release, the values were -1.22 (-1.97, - 0.48), -1.01 (-1.79, -0.23) and -0.19 (-1.13, 0.74) degrees at 3, 6 and 12 months, respectively, when compared to RC repair alone. There were no differences with a RR of 0.92 (0.46, 1.84) between the two groups in terms of complications. After subgroup analysis, RC repair with RI release had no clinically significant differences for pain, function and ROM when compared to RC repair alone in RC tear patients with and without preoperative stiffness. CONCLUSIONS: RC repair with RI release in patients with and without preoperative stiffness had no statistically significant differences for pain, function (CS and ASES) and range of motion (FF, ER and IR) when compared to RC repair alone in RC injury patients. LEVEL OF EVIDENCE: II.

RESUMO

BACKGROUND: Treatment of acute (≤3 weeks) acromioclavicular joint dislocation type III-VI is still controversial. Currently, the two modern techniques that are widely used are hook plate (HP) fixation and coracoclavicular ligament fixation using a suspensory loop device that consists of either a tightrope (single or double), endo-button (single or double), or synthetic ligament and absorbable polydioxansulfate sling. MATERIALS AND METHODS: This systematic review was conducted according to the PRISMA guidelines. Relevant studies that reported Constant-Murley score (CMS), Pain Visual Analog score (VAS) and postoperative complications of either technique were identified from Medline and Scopus from inception to 5 October 2015. RESULTS: Sixteen studies were included for the analysis of HP fixation, and 25 studies were included for analysis of loop suspensory fixation (LSF). Pooling of mean CMS and VAS scores gave 90.35 (95% CI 87.16, 93.54), 1.51 (95% CI 0.73, 2) in the HP group, and 92.48 (95% CI 90.91, 94.05), 0.32 (95% CI 0, 0.64) in the suspensory loop devices group, respectively. The pooled unstandardized mean differences (UMD) scores of CMS and VAS in LSF were 2.13 (95% CI -1.43, 5.69) and -1.19 (95% CI -2.03, -0.35) when compared to hook plating. The pooled prevalence of LSF and hook plating were 0.08 (95% CI 0.06, 0.10) and 0.05 (95% CI 0.02, 0.08) scores. The chance of having complications in the LSF group was 1.69 (95% CI 1.07, 2.60), which was statistically significantly higher than in the HP group. CONCLUSION: LSF have higher shoulder function scores (CMS) and lower postoperative pain when compared to HP fixation; however, there are higher complication rates with LSF when compared to hook plating. LEVEL OF EVIDENCE: IV.

RESUMO

OBJECTIVE: To determine the diagnostic performance of magnetic resonance arthrography (MRA) and magnetic resonance imaging (MRI) in superior labrum anterior to posterior lesions (type II-VII) of the shoulder. MATERIAL AND METHODS: PubMed and Scopus search engines, an electronic search of articles was performed from inception to February 19, 2016. Diagnostic performance of index tests was compared by the summary area under receiver operator characteristic curve (AUROC). RESULTS AND CONCLUSIONS: In all, 117 of 493 studies were eligible and 32 studies (2,013 shoulders) and 11 studies (1,498 shoulders) were evaluated with MRA and MRI. The summary sensitivity, specificity, likelihood ratio (positive and negative) and AUROC were 0.87 (95 % confidence interval, CI: 0.82, 0.91), 0.92 (95 %CI: 0.85, 0.95), 10.28 (95 %CI: 5.84, 18.08), 0.14 (95 %CI: 0.10, 0.20) and 0.94 (95 %CI: 0.92, 0.96) respectively for MRA, and 0.76 (95 %CI: 0.61, 0.86), 0.87 (95 %CI: 0.71, 0.95), 5.89 (95 %CI: 2.5, 13.86), 0.28 (95 %CI: 0.17, 0.47) and 0.94 (95 %CI: 0.92, 0.96) respectively for MRI. The diagnostic performance of MRA was superior to MRI by both direct and indirect comparisons for the detection of SLAP lesions.

RESUMO

Treatment of acute (≤4 weeks) high-grade acromioclavicular (AC) joint separation (types III-VI) is still controversial. Currently, the two modern techniques that are widely used include hook plate fixation and coracoclavicular (CC) ligament fixation using a suspensory loop device (tightrope, synthetic ligament or absorbable polydioxansulfate sling). These techniques are both reported to have superior clinical outcomes. This systematic review and meta-analysis aimed to assess and compare clinical outcomes of hook plate fixation versus fixation of the CC ligament using a loop suspensory fixation (LSF) device for the treatment of AC joint injury. These clinical outcomes consist of the Constant-Murley score (CMS), pain visual analog score (VAS) and postoperative complications. Relevant comparative studies were identified from MEDLINE and Scopus from inception to October 5, 2015. Five of 571 studies were eligible; 5, 3, 3, and 5 studies were included in the pooling of CMS, pain VAS, surgical time and postoperative complications, respectively. The unstandardized mean difference (UMD) of the CMS for LSF was 4.43 [95 % confidence interval (CI) 0.73, 8.14], which was statistically significantly higher than the CMS in hook plate fixation. For VAS, the UMD was 0.02 points (95 % CI -3.54, 3.73) higher than LSF but without statistical significance. The surgical time of LSF was 16.21 min (95 % CI 6.27, 26.15) statistically significantly higher than hook plate fixation. LSF had a lower chance of postoperative complications by 0.62 units (95 % CI 0.30, 1.32) when compared to hook plate fixation, but this also was not statistically significant. In acute high-grade AC joint injuries, loop suspensory fixation had higher postoperative functional CMS and mean surgical time when compared to hook plate fixation. However, for postoperative VAS and complication rates, there were no statistically significant differences between groups.

RESUMO

PURPOSE: To compare the clinical outcomes of osteoarthritis indices (WOMAC and Lequesne scores) and adverse events in the treatment of osteoarthritis (OA) of the knee with platelet-rich plasma (PRP) versus hyaluronic acid (HA) or placebo. METHODS: A systematic review and meta-regression were performed to compare outcomes between PRP injections versus HA or placebo. Relevant randomized control trials were identified from Medline and Scopus from date of inception to 13 August 2015. RESULTS: Nine of 551 studies were eligible; 6, 5, 5, 5, 2, 2, 2 and 7 studies were included in pooling of WOMAC total, pain, stiffness and function scores, Lequesne score, IKDC score, EQ-VAS score and adverse events in OA knee patients, respectively. The PRP injections had -15.4 (95 % CI -28.6, -2.3, p = 0.021), lower mean WOMAC total scores, and 8.83 (95 % CI 5.88, 11.78, p < 0.001), 7.37 (95 % CI 4.33, 10.05, p = 0.021) higher mean IKDC and EQ-VAS scores when compared to HA injections. However, PRP injections had no significant differences in WOMAC pain, stiffness and function scores, as well as Lequesne score and adverse events when compared to HA or placebo. CONCLUSION: In short-term outcomes (≤1 year), PRP injection has improved functional outcomes (WOMAC total scores, IKDC score and EQ-VAS) when compared to HA and placebo, but has no statistically significant difference in adverse events when compared to HA and placebo. This study suggests that PRP injection is more efficacious than HA injection and placebo in reducing symptoms and improving function and quality of life. It has the potential to be the treatment of choice in patients with mild-to-moderate OA of the knee who have not responded to conventional treatment. LEVEL OF EVIDENCE: I.
