Prevalence of Neck Pain among Athletes: A Systematic Review
Many studies have investigated the prevalence of neck pain (NP) and its risk factors in the general population. However, the prevalence of NP among athletes has not yet been systematically investigated. We aimed to systematically review the prevalence of NP in athletes. A comprehensive search was conducted in September 2015 using PubMed, Ovid SP Medline, ISI, and Google Scholar. We included studies in English that reported the prevalence of NP in an athletic population during a defined period of time. We assessed the risk of bias in studies due to various definitions of NP, response rates, and reliability of the study instruments. Two reviewers independently assessed the studies’ quality and performed data extraction. Of 1,675 titles identified, eight articles were assessed for risk of bias, and six with low or moderate risk were included. NP was shown to be prevalent in athletes, with a 1-week prevalence ranging from 8% to 45%, a 1-year prevalence ranging from 38% to 73%, and a lifetime prevalence of about 48%. The prevalence of NP in athletes is high. More studies regarding the prevalence and risk factors of NP may be useful for planning educational programs and developing appropriate rehabilitation protocols and preventive guidelines. Researchers are encouraged to perform epidemiologic studies in athletes with a low risk of bias
Timing of Decompressive Surgery in Patients With Acute Spinal Cord Injury: Systematic Review Update
STUDY DESIGN: Systematic review and meta-analysis.
OBJECTIVE: Surgical decompression is a cornerstone in the management of patients with traumatic spinal cord injury (SCI); however, the influence of the timing of surgery on neurological recovery after acute SCI remains controversial. This systematic review aims to summarize current evidence on the effectiveness, safety, and cost-effectiveness of early (≤24 hours) or late (\u3e24 hours) surgery in patients with acute traumatic SCI for all levels of the spine. Furthermore, this systematic review aims to evaluate the evidence with respect to the impact of ultra-early surgery (earlier than 24 hours from injury) on these outcomes.
METHODS: A systematic search of the literature was performed using the MEDLINE database (PubMed), Cochrane database, and EMBASE. Two reviewers independently screened the citations from the search to determine whether an article satisfied predefined inclusion and exclusion criteria. For all key questions, we focused on primary studies with the least potential for bias and those that controlled for baseline neurological status and specified time from injury to surgery. Risk of bias of each article was assessed using standardized tools based on study design. Finally, the overall strength of evidence for the primary outcomes was assessed using the GRADE approach. Data were synthesized both qualitatively and quantitively using meta-analyses.
RESULTS: Twenty-one studies met inclusion and exclusion criteria and formed the evidence base for this review update. Seventeen studies compared outcomes between patients treated with early (≤24 hours from injury) compared to late (\u3e24 hours) surgical decompression. An additional 4 studies evaluated even earlier time frames:
CONCLUSIONS: This review provides an evidence base to support the update on clinical practice guidelines related to the timing of surgical decompression in acute SCI. Overall, the strength of evidence was moderate that early surgery (≤24 hours from injury) compared to late (\u3e24 hours) results in clinically meaningful improvements in neurological recovery. Further studies are required to delineate the role of ultra-early surgery in patients with acute SCI
Interventions to Optimize Spinal Cord Perfusion in Patients With Acute Traumatic Spinal Cord Injury: An Updated Systematic Review
STUDY DESIGN: Systematic review update.
OBJECTIVES: Interventions that aim to optimize spinal cord perfusion are thought to play an important role in minimizing secondary ischemic damage and improving outcomes in patients with acute traumatic spinal cord injuries (SCIs). However, exactly how to optimize spinal cord perfusion and enhance neurologic recovery remains controversial. We performed an update of a recent systematic review (Evaniew et al, J. Neurotrauma 2020) to evaluate the effects of Mean Arterial Pressure (MAP) support or Spinal Cord Perfusion Pressure (SCPP) support on neurological recovery and rates of adverse events among patients with acute traumatic SCI.
METHODS: We searched PubMed/MEDLINE, EMBASE and ClinicalTrials.gov for new published reports. Two reviewers independently screened articles, extracted data, and evaluated risk of bias. We implemented the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach to rate confidence in the quality of the evidence.
RESULTS: From 569 potentially relevant new citations since 2019, we identified 9 new studies for inclusion, which were combined with 19 studies from a prior review to give a total of 28 studies. According to low or very low quality evidence, the effect of MAP support on neurological recovery is uncertain, and increased SCPP may be associated with improved neurological recovery. Both approaches may involve risks for specific adverse events, but the importance of these adverse events to patients remains unclear. Very low quality evidence failed to yield reliable guidance about particular monitoring techniques, perfusion ranges, pharmacological agents, or durations of treatment.
CONCLUSIONS: This update provides an evidence base to support the development of a new clinical practice guideline for the hemodynamic management of patients with acute traumatic SCI. While avoidance of hypotension and maintenance of spinal cord perfusion are important principles in the management of an acute SCI, the literature does not provide high quality evidence in support of a particular protocol. Further prospective, controlled research studies with objective validated outcome assessments are required to examine interventions to optimize spinal cord perfusion in this setting
Compositional and metabolic quotient analysis of heavy metal contaminated soil after electroremediation
Heavy metal soil contamination provides a danger both to human and environmental ecosystem health and is still on the rise in many developing countries. Electroremediation provides an innovative method to remedy contamination of soils by heavy metals. Fundamental to the acceptance of any soil remedial technique is proof that positive benefits outweigh the negative impacts, in terms of soil health. The environmental effect of electroremediation of heavy metals contaminated soil by some biological indicators was evaluated. A soil contaminated with Zn, Pb, Ni, and Cd was used in a laboratory experiment. Treatment was imposed with a constant voltage gradient of 0.83 V/cm for 20 days. Results indicated that the physicochemical changes caused by the electroremidiation process on the soil microbial population (actinomycetes and gram-positive and negative bacteria), soil respiration and microbial biomass were significant (
P-21: Prevalence of Neck Pain Among Athletes: A Systematic Review
PURPOSE: Many studies have investigated the prevalence of neck pain (NP) and its risk factors in general population. However, the prevalence of NP among athletes has not been systematically investigated yet. We aimed to systematically review the NP prevalence in athletes. As respects of various definitions of NP, response rates and reliability of studies instruments, we considered risk of bias for including studies. METHODS: A comprehensive search was conducted in Sep 2015, using PubMed, Ovid SP Medline, ISI and Google Scholar. We included studies in English that reported the prevalence of NP in an athletic population in a specifically defined period of time. Two reviewers independently assessed the studies' quality, and performed data extractions. RESULTS: Of 1675 titles identified, 8 articles were assessed for bias risk and 6 with low and moderate risk were included. NP was shown to be prevalent in athletes with a oneweek prevalence ranging from 8% to 45%, a one-year prevalence ranging from 38% to 73% and life-time prevalence about 48%. CONCLUSION: Similar to general population, the prevalence of NP in the athletes is high. Therefore, more studies regarding pain prevalences and risk factors may be useful for planning the educational programs, appropriate rehabilitation protocols, and development of preventive guidelines. Researchers are encouraged to perform epidemiologic studies with low risk of bias in this regard

The Role of Ultrasound in Diagnosis of the Causes of Low Back Pain: a Review of the Literature
Context: Low back pain (LBP) is among the most prevalent musculoskeletal conditions in the developed countries. It is a common problem causing disability and imposing a huge economic burden to individuals and state organizations. Imaging plays an important role in diagnosis of the etiology of LBP. Evidence Acquisition: The electronic databases included: PubMed (1950 to present), Ovid SP Medline (1950 to present) and ISI (1982 to present) and Google Scholar. In every search engine another search was performed using various permutations of the following keywords: ultrasonography, ultrasound imaging, low back pain, back muscles, paraspinal muscles, multifidus, transverse abdominis, muscle size, spinal canal, sacroiliac joint and spondylolisthesis. Results: Magnetic resonance imaging (MRI) is widely used in evaluation of patients with LBP; however, high costs, limited availability and contraindications for its use have restricted MRI utilization. In a quest for a less expensive and readily available tool to investigate LBP, clinicians and researchers found ultrasonography (US) as an alternative. In this review we discuss the US application in diagnosis of some common causes of non-specific chronic LBP. Discussed topics include evaluation of spinal canal diameter, paraspinal and transabdominal muscles, sacroiliac joint laxity, pregnancy related LBP, sacroiliitis, and spondylolisthesis using US in patients with LBP. Conclusions: While the first researches on employing ultrasound in diagnosis of patients with LBP had been focused on spinal canal diameter, recent studies have been mostly performed to evaluate the role of transabdominal and paraspinal muscles on core stability and thereby LBP occurrence. On the other side, Doppler ultrasonography has recently played an important role in objective measurement of joint laxity as a common etiology for LBP. Doppler imaging also in pregnant patients with LBP has been recommended as a safe and sensitive method. As conclusion, according to recent and most prestigious studies, focusing more on transabdominal muscle thickness can be considered as future approach in investigations
Relations Between Lateral Abdominal Muscles Thickness Body Mass Index Waist Circumference and Skin Fold Thickness
In light of provided progresses in ultrasound measurements of lateral abdominal muscles, an important role for these muscles, particularly transverse abdominis (TrA) muscle in stability of the spine has been suggested. Some authors have found significant correlations between body mass index (BMI) and thickness of these muscles. The aim of this study was to examine possible association between different methods of measurements of fatness and lateral abdominal muscles thicknesses, employing ultrasound imaging in healthy subjects. Ninety healthy male volunteers aged 18 to 38 (mean= 31.37, standard deviation=5.09) who met our inclusion criteria participated in this study. BMI, skin fold thickness, weight and waist circumference were assumed as the major outcomes for measurement of fatness of the subjects. Employing ultrasound measurements, the thickness of TrA, internal oblique (Int Obl) and external oblique (Ext Obl) muscles were also measured. We found positive significant relation between Ext Obl muscle thickness and all methods of measurements of fatness. Reversely, the results show that Int Obl muscle thickness significantly decreases with the rise of all methods of fatness measurement except weight which had no significant correlation with Int Obl thickness. No significant relation between the TrA muscle thickness and different measurements of the fatness of the subjects were found. In the studies investigate the thickness of lateral abdominal muscles; the authors try to match the participants of different groups of their study regarding the BMI. We found that both waist circumference and skin fold thickness measurements might be assumed as surrogate of BMI, in aim of matching the participants on Ext Obl muscle thickness
