Antenatal corticosteroid (ANC) use before 25 weeks’ gestation is controversial. Our previous systematic review (eight observational studies, n=10 109) showed that ANC exposure was associated with significantly reduced mortality and severe intraventricular haemorrhage (IVH)/periventricular leukomalacia (PVL) in neonates born <25 weeks. We update our review by adding data (n=3334) from a recent study. We used Cochrane methodology and summarised the results using GRADE (The Grading of Recommendations Assessment, Development and Evaluation) guidelines. Nine high-quality observational studies were included. Meta-analysis (random effects model) showed reduced mortality (n=13 443; OR=0.48 (95% CI 0.42 to 0.55) P<0.00001; level of evidence (LOE): moderate) and IVH or PVL (n=8418; OR=0.70 (95% CI 0.63 to 0.79), P<0.00001; LOE: moderate) in neonates born <25 weeks exposed to ANC. There was no difference in necrotising enterocolitis (NEC) ≥stage II (n=8737; OR=1.01 (95% CI 0.84 to 1.22), P=0.89; LOE: low); incidence of chronic lung disease (CLD) was higher (n=7983; OR=1.32 (95% CI 1.04 to 1.67), P=0.02; LOE: low) in ANC group. Composite outcomes of death/major morbidities (eg, severe IVH, NEC, CLD) were improved after ANC exposure.

ObjectiveThis meta-analysis aimed to assess the efficacy of antenatal corticosteroids (ACS) on morbidity and mortality among preterm multiple pregnancies.MethodsThe PubMed, Embase, Web of Science and Cochrane Library databases were searched for studies investigating the outcomes among preterm multiple gestations following to ACS, from their inception to 1 November 2020. Two authors independently performed the study selection, risk of bias assessment and data extraction. The primary outcomes were respiratory distress syndrome (RDS) and mortality and secondary outcomes included intraventricular haemorrhage (IVH), periventricular leukomalacia (PVL), necrotising enterocolitis, retinopathy of prematurity and bronchopulmonary dysplasia. Pooled ORs were obtained using random effects models. Subgroup analyses were performed to explain heterogeneity by ACS completeness, administration-to-delivery intervals (≤7 days) and single or multicentre.ResultsA total of 16 observational studies with 36 973 newborns were included in the meta-analysis. ACS treatment was associated with a reduction in RDS (OR 0.66; 95% CI 0.54 to 0.82; I2=91.4%; p<0.001), mortality (OR 0.64; 95% CI 0.50 to 0.81; I2=85.9%; p<0.001), IVH (OR 0.67; 95% CI 0.54 to 0.83; I2=77.4%; p<0.001) and PVL (OR 0.65; 95% CI 0.47 to 0.92; I2=75.5%; p<0.001). Subgroup analyses showed ACS completeness, administration-to-delivery interval and multicentre study affected these associations.DiscussionACS may be beneficial for reducing the risks of RDS, mortality, IVH and PVL among preterm multiple gestations. The efficacy of ACS could be affected by ACS completeness and administration-to-delivery. More robust evidence on the efficacy of ACS treatment among multiple gestations is warranted.

Many studies have analyzed the effects of β-cryptoxanthin (BCX) on osteoporosis and bone health. This systematic review and meta-analysis aimed at providing quantitative evidence for the effects of BCX on osteoporosis. Publications were selected and retrieved from three databases and carefully screened to evaluate their eligibility. Data from the final 15 eligible studies were extracted and uniformly summarized. Among the 15 studies, seven including 100,496 individuals provided information for the meta-analysis. A random effects model was applied to integrate the odds ratio (OR) to compare the risk of osteoporosis and osteoporosis-related complications between the groups with high and low intake of BCX. A high intake of BCX was significantly correlated with a reduced risk of osteoporosis (OR = 0.79, 95% confidence interval (CI) 0.70–0.90, p = 0.0002). The results remained significant when patients were stratified into male and female subgroups as well as Western and Asian cohorts. A high intake of BCX was also negatively associated with the incidence of hip fracture (OR = 0.71, 95% CI 0.54–0.94, p = 0.02). The results indicate that BCX intake potentially reduces the risk of osteoporosis and hip fracture. Further longitudinal studies are needed to validate the causality of current findings.

Very-low-carbohydrate diets or ketogenic diets are frequently used for weight loss in adults and as a therapy for epilepsy in children. The incidence and characteristics of kidney stones in patients on ketogenic diets are not well studied. Methods: A systematic literature search was performed, using MEDLINE, EMBASE, and Cochrane Database of Systematic Reviews from the databases’ inception through April 2020. Observational studies or clinical trials that provide data on the incidence and/or types of kidney stones in patients on ketogenic diets were included. We applied a random-effects model to estimate the incidence of kidney stones. Results: A total of 36 studies with 2795 patients on ketogenic diets were enrolled. The estimated pooled incidence of kidney stones was 5.9% (95% CI, 4.6–7.6%, I2 = 47%) in patients on ketogenic diets at a mean follow-up time of 3.7 +/− 2.9 years. Subgroup analyses demonstrated the estimated pooled incidence of kidney stones of 5.8% (95% CI, 4.4–7.5%, I2 = 49%) in children and 7.9% (95% CI, 2.8–20.1%, I2 = 29%) in adults, respectively. Within reported studies, 48.7% (95% CI, 33.2–64.6%) of kidney stones were uric stones, 36.5% (95% CI, 10.6–73.6%) were calcium-based (CaOx/CaP) stones, and 27.8% (95% CI, 12.1–51.9%) were mixed uric acid and calcium-based stones, respectively. Conclusions: The estimated incidence of kidney stones in patients on ketogenic diets is 5.9%. Its incidence is approximately 5.8% in children and 7.9% in adults. Uric acid stones are the most prevalent kidney stones in patients on ketogenic diets followed by calcium-based stones. These findings may impact the prevention and clinical management of kidney stones in patients on ketogenic diets.

Background: Studies have shown that preventive psychological interventions can reduce the occurrence of sports injuries. Purpose: To systematically evaluate the published literature on the effects of psychological interventions on rates of sports injuries and propose a set of psychological interventions to reduce such injuries. Study Design: Systematic review; Level of evidence, 1. Methods: A total of 11 randomized controlled trials and intervention control trials involving 1287 participants were included. A random-effects model was used to analyze the data. Pooled results were expressed as effect sizes and 95% CIs. Bias and heterogeneity among the studies were assessed, and sensitivity and subgroup analyses were performed. Results: Meta-analysis suggested that preventive psychological interventions effectively prevented the occurrence of sports injuries (effect size = –0.55; P < .001), although the studies showed substantial heterogeneity ( I 2 = 94.2%; P < .001), which could not be attributed to specific variables. Nevertheless, sensitivity analysis suggested that overall results were reliable. No significant risk of publication bias was found. Conclusion: Preventive psychological interventions moderately reduced the risk of sports injuries. Risk screening also significantly reduced the risk of sports injuries. These interventions should focus on cognitive behavior and be administered in 1 to 6 sessions over 7 to 12 weeks for 60 minutes per session.

Objectives We investigated the association between the consumption of fresh and processed fish and glioma risk using a meta-analysis approach. Methods We selected and analyzed observational studies that discussed the relationships between fresh and processed fish intake on glioma risk from PubMed, Web of Science, Embase, and the SinoMed and Wanfang databases from inception to 31 March 2020. Studies were selected according to pre-established eligibility criteria and data were extracted separately by two researchers. A meta-analysis was conducted based on a random-effects model to provide pooled odds ratios (OR) and 95% confidence intervals (CIs). Results Eight studies considered the relationship between fish intake (seven fresh and seven processed fish) and glioma risk and were included in this meta-analysis. The OR effect size for fresh fish intake and glioma risk was 0.72 (95%CI 0.53–0.97) and the overall OR effect size for processed fish intake and glioma risk was 1.88 (95%CI 1.06–3.34). Conclusion Dietary intake of fresh fish may reduce the risk of glioma, but consumption of processed fish may increase the risk of glioma. This study had some limitations, and further studies are therefore required to clarify the associations between fish intake and glioma risk.

ContextThe association between maternal diabetes and outcomes of infants who are born preterm is unclear.ObjectiveTo perform a systematic review and meta-analysis of clinical studies exploring the association between maternal diabetes and preterm infant outcomes.MethodsMedline, PubMed and Cumulative Index of Nursing and Allied Health Literature databases were searched without language restriction from 1 January 2000 until 19 August 2019. Studies examining preterm infants <37 weeks gestational age and reporting prespecified outcomes of this review based on maternal diabetes as primary exposure variable were included.ResultsOf 7956 records identified through database searches, 9 studies were included in the study. No significant association was found between maternal diabetes and in-hospital mortality (adjusted RR (aRR) 0.90 (95% CI 0.73 to 1.11); 6 studies; participants=1 191 226; I2=83%). Similarly, no significant association was found between maternal diabetes and bronchopulmonary dysplasia (aRR 1.00 (95% CI 0.92 to 1.07); 4 studies; participants=107 902; I2=0%), intraventricular haemorrhage or cystic periventricular leukomalacia (aRR 0.91 (95% CI 0.80 to 1.03); 3 studies; participants=115 050; I2=0%), necrotising enterocolitis (aRR 1.13 (95% CI 0.90 to 1.42); 5 studies; participants=142 579; I2=56%) and retinopathy of prematurity (ROP) (aRR 1.17 (95% CI 0.85 to 1.61); 5 studies; participants=126 672; I2=84). A sensitivity analysis where low risk of bias studies were included in the meta-analyses showed similar results; however, the heterogeneity was lower for in-hospital mortality and ROP.ConclusionMaternal diabetes was not associated with in-hospital mortality and severe neonatal morbidities in preterm infants. Future studies should explore the association between the severity of maternal diabetes with preterm infant outcomes.

Objective:To investigate the effectiveness of cryotherapy on pain and physical function in knee osteoarthritis.Data sources:An electronic search was performed up to February 2019 on PubMed/MEDLINE, EMBASE, CINAHL, Lilacs, Cochrane, Web of Science, Ibecs, and Scielo databases with keywords knee osteoarthritis and cryotherapy.Methods:Two authors independently performed the study selection. All languages and publication dates were considered. The PEDro scale was used to assess the methodological quality of the studies, and the body of evidence was analyzed and synthesized using the Grading of Recommendations, Assessment, Development, and Evaluation approach. The clinical relevance of the included studies was evaluated using the criteria proposed in the Cochrane Handbook for Systematic Reviews of Interventions.Results:Of the five studies, 202 subjects were included. All studies included participants with established knee osteoarthritis. The mean PEDro score was 4.20/10, and meta-analysis was not possible due to heterogeneity among the studies. The mean clinical relevance was 3/5. Only two studies were considered for analysis based on the GRADE approach, and low level of evidence was synthesized regarding the effectiveness of cryotherapy for pain management, knee stiffness, knee range of motion, and physical function. Application techniques, frequency, and duration did not affect outcomes.Conclusions:There were insufficient primary studies to draw any conclusions about the effectiveness of cryotherapy on pain and physical function on individuals with knee osteoarthritis.

The objective of this systematic review was to evaluate the association between a soy-based infant diet and the onset of puberty. We included studies in which children were fed a soy-based diet, and we compared them with those who were not. The primary outcomes were the onset of puberty in girls (thelarche, pubarche, and menarche age), boys (pubarche, voice change, testicular and penis enlargement age), and both (risk of delayed and precocious puberty [PP]). Search strategies were performed in PubMed, Embase, LILACS, and CENTRAL databases. Two reviewers selected eligible studies, assessed the risk of bias, and extracted data from the included studies. The odds ratio (OR) and mean difference (MD) were calculated with a 95% confidence interval (CI) as a measure of the association between soy consumption and outcomes. We used a random-effects model to pool results across studies and the Grading of Recommendations Assessment, Development, and Evaluation to evaluate the certainty of evidence. We included eight studies in which 598 children consumed a soy-based diet but 2957 did not. The primary outcomes that could be plotted in the meta-analysis were the risk of PP and age at menarche. There was no statistical difference between groups for PP (OR: 0.51, 95% CI: 0.09 to 2.94, 3 studies, 206 participants, low certainty of evidence). No between-group difference was observed in menarche age (MD 0.14 years, 95% CI -0.16 to 0.45, 3 studies, 605 children, low certainty of evidence). One study presented this outcome in terms of median and interquartile range, and although the onset of menarche was marginally increased in girls who received a soy-based diet, the reported age was within the normal age range for menarche. We did not find any association between a soy-based infant diet and the onset of puberty in boys or girls. Trial Registration: PROSPERO registration: CRD42018088902.

Lisfranc Injuries

Aims This systematic review and meta-analysis was conducted to compare open reduction and internal fixation (ORIF) with primary arthrodesis (PA) in the treatment of Lisfranc injuries, regarding patient-reported outcome measures (PROMs), and risk of secondary surgery. The aim was to conclusively determine the best available treatment based on the most complete and recent evidence available. Methods A systematic search was conducted in PubMed, Cochrane Controlled Register of Trials (CENTRAL), EMBASE, CINAHL, PEDro, and SPORTDiscus. Additionally, ongoing trial registers and reference lists of included articles were screened. Risk of bias (RoB) and level of evidence were assessed using the Cochrane risk of bias tools and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) tool. The random and fixed-effect models were used for the statistical analysis. Results A total of 20 studies were selected for this review, of which 12 were comparative studies fit for meta-analysis, including three randomized controlled trials (RCTs). This resulted in a total analyzed population of 392 patients treated with ORIF and 249 patients treated with PA. The mean differences between the two groups in American Orthopedic Foot and Ankle Society (AOFAS), VAS, and SF-36 scores were -7.41 (95% confidence interval (CI) -13.31 to -1.51), 0.77 (95% CI -0.85 to 2.39), and -1.20 (95% CI -3.86 to 1.46), respectively. Conclusion This is the first study to find a statistically significant difference in PROMs, as measured by the AOFAS score, in favour of PA for the treatment of Lisfranc injuries. However, this difference may not be clinically relevant, and therefore drawing a definitive conclusion requires confirmation by a large prospective high-quality RCT. Such a study should also assess cost-effectiveness, as cost considerations might be decisive in decision-making. Level of Evidence: I Cite this article: Bone Jt Open 2021;2(10):842–849.

Abstract Objective To systematically review and meta-analyze the role of lactoferrin supplementation to prevent late-onset sepsis (LOS) in preterm infants. Study Design Database search include PubMed, Web of Science, and Cochrane central for randomized clinical trial (RCTs). The Cochrane Grading of Recommendations Assessment, Development, and Evaluation methodology was used for summarizing the results. Results Ten RCTs involving 3,679 infants were included. Lactoferrin supplementation with or without probiotics decreased all LOS (relative risk [RR]: 0.56; 95% confidence interval [CI]: 0.36–0.86; I 2 = 58%; 10 studies; 3,470 subjects; level of evidence [LOE]: low) significantly. Similarly, lactoferrin supplementation without probiotics decreased all LOS (RR: 0.43; 95% CI: 0.29–0.62; I 2 = 0%; 8 studies; 1,209 subjects; LOE: moderate) significantly. Lactoferrin supplementation did not significantly reduce necrotizing enterocolitis (RR: 0.62; 95% CI: 0.29–1.33; I 2 = 43%; 6 studies; 3,079 subjects; LOE: low), all-cause mortality (RR: 0.74; 95% CI: 0.36–1.53; I 2 = 53%; 8 studies; 3,395 subjects; LOE: very low), bronchopulmonary dysplasia (RR: 1; 95% CI: 0.90–1.13; I 2 = 0%; 4 studies; 2,570 subjects; LOE: moderate), and threshold retinopathy of prematurity eligible for surgical treatment (RR: 0.61; 95% CI: 0.25–1.51; I 2 = 74%; 2 studies; 2,481 subjects; LOE: very low). Conclusion Low to moderate quality evidence suggests that lactoferrin supplementation reduces LOS in preterm infants. Further research is needed to improve the certainty in the evidence.
