This meta-analysis examined the association of birth order on divergent thinking (DT). The main purpose was to reveal how ordinal position (only, first, middle, or last-born) relates to creativity. The results of 27 studies (k = 222) were analyzed using a multilevel approach. Since some previous studies compared first- vs. later-born children whereas others compared different ordinal positions in DT, three datasets were analyzed: (a) first-born vs. later-born children, (b) only children vs. children with siblings, and (c) middle-born vs. later-born children. Results showed that first-borns had higher DT scores than later-born children (g = -0.165, 95% CI [-0.012, -0.318], p = .046). Moderator analysis showed a significant interaction between gender and task modality with later-born males scoring lower on figural DT than first-born males. No significant difference was found between only children and first-born children with siblings. Moreover, the results showed a non-significant difference between middle- and later-born children; however, moderator analysis indicated that gender and age significantly explained some variability in the mean effect. Limitations and practical implications of the findings are discussed.

Objective To systematically review the current literature regarding the operative outcomes of stapes surgery for stapes fixation via the endoscopic and microscopic approaches. Data Sources PubMed, Embase, and Web of Science. Review Methods An electronic search was conducted with the keywords “endoscop* or microscop*” and “stapes surgery or stapedectomy or stapedotomy or otosclerosis or stapes fixation.” Studies were included if they compared endoscopy with microscopy for stapes surgery performed for stapes fixation and evaluated hearing outcomes and postoperative complications. Articles focusing on stapes surgery other than for stapes fixation were excluded. Results The database search yielded 1317 studies; 12 remained after dual-investigator screening for quantitative analysis. The mean MINORS score was 18 of 24, indicating a low risk of bias. A meta-analysis demonstrated no statistically significant difference between the groups with regard to operative time, chorda tympani nerve manipulation or sacrifice, or postoperative vertigo. There was a 2.6-dB mean improvement in the change in air-bone gap in favor of endoscopic stapes surgery and a 15.2% increased incidence in postoperative dysgeusia in the microscopic group, but the studies are heterogeneous. Conclusions Endoscopic stapes surgery appears to be a reasonable alternative to microscopic stapes surgery, with similar operative times, complications, and hearing outcomes. Superior visibility with the endoscope was consistently reported in all the studies. Future studies should have standardized methods of reporting visibility, hearing outcomes, and postoperative complications to truly establish if endoscopic stapes surgery is equivalent or superior to microscopic stapes surgery.

Introduction There is controversy if direct to comprehensive center “mothership” (MS) or stopping at primary center for thrombolysis before transfer to comprehensive center “drip-and- ship” (DS) are best models of treatment of acute stroke. In this study, we compare MS and DS models to evaluate the best option of functional outcome. Methods Studies between 1990 and 2020 were extracted from online electronic databases. We compared the clinical outcomes, critical time measurements, functional independence and mortality were then compared. Results A total of 7,824 patients’ data were retrieved from 13 publications (3 randomized control trials and 10 retrospective ones). 4,639 (59.3%) patients were treated under MS model and 3,185 (40.7%) followed the DS model with mean age of 70.01±3.58 vs. 69.03±3.36; p< 0 .001, respectively. The National Institute Health Stroke Scale was 15.57±3.83 for the MS and 15.72±2.99 for the DS model (p=<0.001). The mean symptoms onset-to-puncture time was significantly shorter in the MS group compared to the DS (159.69 min vs. 223.89 min; p=<0.001, respectively). Moreover, the collected data indicated no significant difference between symptom’s onset to intravenous (IV) thrombolysis time and stroke onset-to-successful recanalization time (p=0.205 and p=<0.001, respectively). Patients had significantly worse functional outcome [modified rankin score (mRS)] (3-6) at 90-days in the DS model [Odds Ratio (OR): 1.47, 95% Confidence Interval (CI): 1.13-1.92, p<0.004] and 1.49-folds higher likelihood of symptomatic intracerebral hemorrhage (OR: 1.49, 95%CI: 1.22-1.81, p<0.0001) compared to MS. However, there were no statistically significant difference in terms of mortality (OR: 1.16, 95%CI: 0.87-1.55, p=0.32) and successful recanalization (OR: 1.12, 95%CI: 0.76-1.65, p=0.56) between the two models of care. Conclusion Patients in the MS model have significantly improved functional independence and recovery. Further studies are needed as the data from prospectively randomized studies is not of sufficient quality to make definite recommendations.

Background: The emergence of acne scars due to skin damage in the acne healing process and causes psychological effects. The management of acne scars can be done in several methods. Microneedling is a very simple, safe, effective, and minimally invasive therapeutic technique compared to other therapeutic modalities in acne scars. The resulting wound is micro-sized, and promotes the growth of growth factors and collagen production. We aimed to assess the effectiveness of using microneedling as an acne scar treatment option. A systematic review and meta-analysis were qualitatively and quantitatively conducted from RCTs, assessing the effectiveness of microneedling in reducing the severity of acne scars according to Goodman and Baron in the treatment of acne scars. Methods: Medline Pubmed, PMC, Scopus, Google Scholar, and JDC library, eligible search. Ten studies (n=514) were analyzed qualitatively with 2 studies (n=53 subjects) and quantitatively analyzed by 2 studies (n=90 subjects). Both analyzes were included in the meta-analysis. The mean age of the participants was 40.5 years. The application of microneedling intervention as monotherapy or a combination in patients with acne scarring was followed for at least 16 weeks, the results obtained were the mean reduction in the degree of acne scarring after microneedling. Result: The combination of microneedling treatment obtained a qualitative decrease in the degree of acne scars according to Goodman and Baron with a Z value (-4.299) and P=<0.001 lower than the control (PRP) with a significant difference. The quantitative decrease in the degree of acne scars according to Goodman and Baron obtained a Z value (-4.681) and P=<0.001 lower than the control (PRP) with a significant difference. Quantitative reduction in the degree of acne scars according to Goodman and Baron on single therapy between treatment and control with a value of Z (-3.536) and P=<0.001 lower than control (fractional CO2) with a significant difference. The results of the degree of acne scars in the group treated with microneedling alone or in combination were lower than the control group. The mean before and after therapy compared to the control there was a significant difference. Conclusion. The results of a systematic review, concluded that the group treated with microneedling had a decrease in the degree of acne scarring according to Goodman and Baron with P=<0.001 compared to before treatment. The decrease was shown in the difference in Z values, which was significantly greater than the control given other therapies. Microneedling therapy can be an alternative therapy option for acne scar patients who are unresponsive to previous therapy or in conditions where there are contraindications to other therapies.

Abstract Background There is dearth of information on COVID-19’s impact on pregnant women. However, literature reported trends of COVID-19 differ, depending on the presence of clinical features upon presentation. Objective This systematic review aimed to assess differences in risk factors, management, complications, and pregnancy and perinatal outcomes in symptomatic vs. asymptomatic pregnant women with confirmed SARS-CoV-2 infection. Methods A search was run on electronic databases to identify studies reporting COVID-19 in pregnancy. Meta-analysis was performed and odds ratios and mean difference with 95% confidence intervals were calculated using Review Manager 5.4. Review Prospero registration number CRD42020204662. Results We included ten articles reporting data from 3158 pregnancies; with 1900 symptomatic and 1258 asymptomatic pregnant women. There was no significant difference in the mean age, gestational age, and body mass index between the two groups. The meta-analysis suggested that pregnant women who were obese (OR:1.37;95%CI:1.15 to 1.62), hypertensive (OR:2.07;95%CI:1.38 to 3.10) or had a respiratory disorder (OR:1.64;95%CI:1.25 to 2.16), were more likely to be symptomatic when infected with SARS-CoV-2. Pregnant women with Black (OR:1.48;95%CI:1.19 to 1.85) or Asian (OR:1.64;95%CI:1.23 to 2.18) ethnicity were more likely to be symptomatic while those with White ethnicity (OR:0.63;95%CI:0.52 to 0.76) were more likely to be asymptomatic. Cesarean-section delivery (OR:1.40;95%CI:1.17 to 1.67) was more likely amongst symptomatic pregnant women. The mean birthweight(g) (MD:240.51;95%CI:188.42 to 293.51), was significantly lower, while the odds of low birthweight (OR:1.85;95%CI:1.06 to 3.24) and preterm birth (< 37 weeks) (OR:2.10;95%CI:1.04 to 4.23) was higher amongst symptomatic pregnant women. Symptomatic pregnant women had a greater requirement for maternal ICU admission (OR:13.25;95%CI:5.60 to 31.34) and mechanical ventilation (OR:15.56;95%CI:2.96 to 81.70) while their neonates had a higher likelihood for Neonatal Intensive Care Unit admission (OR:1.96;95%CI:1.59 to 2.43). The management strategies in the included studies were poorly discussed, hence could not be analyzed. Conclusion The evidence suggests that the presence of risk factors (co-morbidities and ethnicity) increased the likelihood of pregnant women being symptomatic. Higher odds of complications were also observed amongst symptomatic pregnant women. However, more adequately conducted studies with adjusted analysis and parallel comparison groups are required to reach conclusive findings.

Purpose. Intravitreal antivascular endothelial growth factor (anti-VEGF) therapy has been widely used for the treatment of neovascularization (NV) secondary to age-related macular degeneration (AMD). This study aimed to compare the efficacy among different subtypes of neovascular age-related macular degeneration (nAMD). Methods. PubMed, Embase, and the Cochrane Library were searched for eligible studies. We performed meta-analysis using Review Manager 5.3 and Stata/SE 12.0. Results. A total of 24 studies met our inclusion criteria and were included in the systematic review. At 3 months, the mean logarithm of the minimum angle of resolution (logMAR) improvements were −0.09, −0.18, and −0.23 for type 1, 2, and 3, respectively, while the mean macular thickness (MT) changes were −104.83, −130.76, and −196.29 μm. At 12 months, the mean changes in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters were 6.38, 8.12, and 9.37, while the MT decrease was 126.51, 126.52, and 139.85 μm, respectively. However, statistically significant difference was only found between type 1 and 3 in vision improvement, both in the short term (p=0.0002) and long term (p=0.01). Conclusions. The reactivity to VEGF inhibitors varied among different subtypes of nAMD. The efficacy of intravitreal anti-VEGF therapy in type 3 nAMD was statistically better than type 1 when considering vision improvement at 3 and 12 months. Thus, the lesion subtype is a predictor for the treatment outcome which can help guide prognosis.

Background. An increase in the mean platelet volume (MPV) has been proposed as a novel prognostic indicator in critically ill patients.Objective. We conducted a systematic review and meta-analysis to determine whether there is an association between MPV and mortality in critically ill patients.Methods. We did electronic search in Medline, Scopus, and Embase up to November 2015.Results. Eleven observational studies, involving 3724 patients, were included. The values of initial MPV in nonsurvivors and survivors were not different, with the mean difference with 95% confident interval (95% CI) being 0.17 (95% CI: −0.04, 0.38;p=0.112). However, after small sample studies were excluded in sensitivity analysis, the pooling mean difference of MPV was 0.32 (95% CI: 0.04, 0.60;p=0.03). In addition, the MPV was observed to be significantly higher in nonsurvivor groups after the third day of admission. On the subgroup analysis, although patient types (sepsis or mixed ICU) and study type (prospective or retrospective study) did not show any significant difference between groups, the difference of MPV was significantly difference on the unit which had mortality up to 30%.Conclusions. Initial values of MPV might not be used as a prognostic marker of mortality in critically ill patients. Subsequent values of MPV after the 3rd day and the lower mortality rate unit might be useful. However, the heterogeneity between studies is high.

BackgroundCompared with current imaging methods, the diagnostic performance and the advantages and limitations of optical coherence tomography angiography (OCTA) remain unclear. We performed a systematic review and meta-analysis of studies investigating vessel density (VD) in patients with glaucoma using OCTA.MethodsWe conducted a literature search on PubMed, Scopus, Web of Science, ISI Conference Proceedings and Google Scholar, along with a manual search, from January 2006 to March 2018. We included prospective studies that used OCTA to compare the VD in glaucomatous eyes with healthy control eyes.ResultsOf 3045 screened articles, 24 were included in a broad characterisation and 18 in the meta-analysis. We observed a statistically significant reduction in the mean peripapillary VD (MPVD) in glaucoma (MPVD: 57.53%, 95% CI 52.60 to 62.46, p< 0.001) compared with controls (MPVD: 65.47%, 95% CI 59.82 to 71.11; standardised mean difference [SMD], –1.41, 95% CI –1.62 to –1.20, p< 0.001) for 888 glaucomatous and 475 healthy eyes, and also in the mean-whole optic nerve image VD (SMD, –9.63, 95% CI –10.22 to –9.03, p<0.001), mean inside-disc VD (SMD, − 9.51, 95% CI –12.66 to –6.36, p<0.05) and mean parafoveal VD (SMD, –3.92, 95% CI –4.73 to –3.12, p<0.001). Subgroup analyses revealed a significant difference in the MPVD across glaucoma subtypes and OCTA devices.ConclusionThis suggests the diagnostic utility of OCTA in detecting glaucomatous eyes; however, further longitudinal prospective studies are welcomed to characterise vascular changes in glaucoma.

The objective of the present study was to perform a meta-analysis that compared the chemical composition of corn silage produced for different experimental purposes, i.e., by research groups that studied corn silage (SCS) or by research groups that only used corn silage (UCS) as a form of roughage. We analyzed 203 papers that were published between January 1994 and December 2014 and contained a total of 647 treatments and the analysis of 1701 silos. We found a significant difference (P < 0.0001) in the dry matter (DM) content of SCS silage (33.00%) and that of UCS silage (30.64%). The DM contents of neutral detergent fiber for the SCS and UCS silage were high (54.72 and 55.14% DM, respectively) but were not significantly different from one another (P = 0.5936), and the acid detergent fiber content of the UCS silage (31.04% DM) was higher than that of the SCS silage (29.65%, P = 0.0214), which indicated that the UCS silage was less digestible than the SCS silage. This was also corroborated (P = 0.0064) by the mean content of total digestible nutrients (64.18% DM) in the UCS silage, which likely results from the lower level of care taken when using standard silage production methods, compared to that taken by SCS researchers. Therefore, we concluded that the corn silage produced by research groups in Brazil are not analyzed in full and that, as a result, there is a paucity of important information, such as the content of organic acids. In addition, we also found that corn silage produced in Brazil contains a high level of neutral detergent fiber.

Background of Study: More research studies are being completed advocating for the use of exercise as an intervention and form of treatment for concussions. However, exercise can include many forms of physical activity, intensities, and durations. This systemic review and meta-analysis focused on the use of aerobic exercise, such as cycling or walking, as an intervention and form of treatment for children and young adults suffering from a concussion. Objective: The purpose of this systematic review and meta-analysis was to determine if the addition of aerobic exercise to an individual concussion treatment makes a significant difference when compared to treatments using flexibility as a form of physical activity or traditional methods of treatment following guidelines from the 2016 Berlin Consensus Statement on Concussion in Sport. Method: The search conducted for articles generated 472 studies. Out of these, 5 studies were selected based from the inclusion criteria. Results: Aerobic exercise was shown to significantly decrease the absolute risk difference for the development of prolonged post-concussion symptoms in children and adolescents with concussions when compared to those who reported no physical activity. The mean risk difference for the independent variable (IV) was -0.12 with a 95% confidence interval was reported to be -0.17 to -0.07 and an effect size of Z = 4.94 (P < 0.00001). Aerobic exercise was also shown to have an effect on the change in post-concussion symptom scale scores. The mean IV difference was 8.7 with a 95% confidence interval of 2.05 to 14.35 and an effect size of Z=3.02 (p=0.003). Conclusion: In conclusion, while there is evidence that aerobic exercise is beneficial for children and adolescents with a concussion, more studies need to be completed focusing on this age group and the effects of aerobic exercise on concussion recovery.

Background: Coracoid process transfer for the treatment of recurrent glenohumeral dislocations is a safe and reliable procedure; however, there is no consensus as to which is the best method, the Bristow or Latarjet procedure. Purpose: To analyze the results of coracoid process transfer for the treatment of recurrent glenohumeral dislocations and to compare the results of this transfer between the Bristow and Latarjet techniques. Study Design: Systematic review; Level of evidence, 4. Methods: The databases surveyed for this review included J-STAGE; Cochrane Bone, Joint and Muscle Trauma Group Specialized Register; Cochrane Controlled Register of Trials; MEDLINE; Ovid; Embase; Google Scholar; and CINAHL. Inclusion criteria consisted of (1) studies related to anterior glenohumeral dislocations treated with transfer of the coracoid process to the anterior glenoid rim and (2) studies that could provide data to perform at least 1 meta-analysis or other statistical evaluation. Titles and abstracts were reviewed for inclusion; thereafter, outcomes and the risk of bias were extracted. Statistical analyses were performed according to the nature of the data. When possible, the 95% CI was included. Results: Of the 779 studies found, 63 were able to provide data assessing 3395 shoulders. There were no randomized, blinded, or double-blinded trials. The recurrence of dislocations was assessed in 41 studies that used the Bristow technique (n = 2346 shoulders; percentage redislocations [mean ± SE], 1.00% ± 0.20%) and 18 studies that used the Latarjet technique (n = 930 shoulders; percentage redislocations, 2.13% ± 0.49%) ( P = .04). The mean loss of external rotation was 12.91° for the Bristow procedure (n = 1440 shoulders) and 11.70° for the Latarjet procedure (n = 243 shoulders). The mean quality-of-life outcome scores were as follows for the Bristow and Latarjet procedures, respectively: Rowe score, 92.06 and 89.33; Western Ontario Shoulder Instability Index score, 16.44% and 19.68%; Japanese Orthopaedic Association score, 93.28 and 92.00; and American Shoulder and Elbow Surgeons score, 91.00 and 89.90. Conclusion: Transferring the coracoid to the anteroinferior border of the glenoid through the subscapularis tendon is effective, regardless of the technique. When comparing the Bristow and Latarjet techniques, the recurrence of dislocations was the only outcome that could undergo a meta-analysis, and it presented a statistically significant difference in favor of the Bristow procedure. All other outcomes presented no clinically significant differences between their effect sizes. More studies presenting better methodology are still needed to achieve more robust conclusions.
