Review
Females have increased pain sensitivity and are more vulnerable to chronic pain conditions. Sleep disturbances are comorbid with chronic pain and exacerbate pain symptoms. Different types of sleep disturbance affect pain perception distinctly, but it is not clear if these effects are equal in men and women. This systematic review investigated potential differences in how sleep disturbance affects pain in males and females. We searched EBSCO, MEDLINE, Psych INFO, Science Direct, and Web of Science from January 2001 to November 2022 and found 38 studies with 978 participants. Separate random-effects models were used to estimate the pooled effect sizes based on standardized mean differences (SMDs) of experimental sleep disturbance paradigms on various pain outcomes. Sex moderated the effect of sleep disturbance on pain facilitation (SMD = 0.13; 95%CI: 0.004 to 0.022; p=.009) and pain inhibition (SMD = 0.033; 95%CI: 0.011 to 0.054; p=.005), with increased facilitation and decreased inhibition in females, but the opposite effect in males. Further, age moderated the effects of total sleep deprivation (SMD = -0.194; 95%CI -0.328 to -0.060; p=.008) on pain sensitivity and fragmented sleep (SMD = -0.110; 95%CI: 0.148 to -0.072; p<.001) on pain threshold. While the moderating effect of sex and age on the sleep-pain relationship was small, these factors need to be considered in future sleep-pain research.

Review
BACKGROUND
Fibromyalgia syndrome (FM) is a chronic pathology characterised by widespread pain commonly associated with psychological distress affecting quality of life. In recent years, transcranial direct current stimulation (tDCS) and transcranial magnetic stimulation (TMS) have been investigated to treat chronic pain. The aim of the current review is to determine the effects of tDCS and TMS on the main symptoms of patients with FM.
DEVELOPMENT
A systematic review based on PRISMA guidelines was carried out. The search strategy was performed in MEDLINE, SCOPUS, PEDro and Cochrane Library. Randomised controlled trials based on the effects of tDCS and TMS on pain, pressure pain threshold (PPT), fatigue, anxiety and depression, catastrophising and quality of life in patients with FM were analysed. Fourteen studies were included.
CONCLUSIONS
The application of tDCS to the motor cortex is the only intervention shown to decrease pain in the short and medium-term in patients with FM. The application of both interventions showed improvements in PPT, catastrophising and quality of life when applied to the motor cortex, and in fatigue when applied to the dorsolateral prefrontal cortex. The effects of these interventions on anxiety and depression are unclear.

European Review For Medical and... Jun 2023This systematic review was carried out to review ischemic pressure and post-isometric relaxation for treatment of rhomboid latent myofascial trigger point. (Meta-Analysis)
Meta-Analysis
OBJECTIVE
This systematic review was carried out to review ischemic pressure and post-isometric relaxation for treatment of rhomboid latent myofascial trigger point.
MATERIALS AND METHODS
This systematic review was organized using PRISMA and Cochrane standards. This meta-analysis compares ischemic pressure to post-isometric relaxation for rhomboid latent myofascial trigger point. Search terms included: myofascial pain, trigger point, ischemia pressure, post-isometric relaxation, and electric stimulation. We first searched MEDLINE (including ePub, Ahead of Print, InProgress, and Other Non-Indexed Citations) and then EMBASE and the Cochrane CENTRAL Register of Controlled Trials. Searches were conducted from the databases' inception through August 2022.
RESULT
The RCT review followed PRISMA criteria. PubMed, Embase, PSYCHInfo, and the Cochrane Library were searched from their origin without language constraints to locate all RCTs linked to ischemic pressure vs. post-isometric relaxation for therapy of rhomboid latent myofascial trigger point. 463 duplicates were removed. 140 of 174 citations were removed. Seven high-quality full-text papers out of 34 were included.
CONCLUSIONS
Conservative and noninvasive treatments can only raise pain tolerance. Compared to standard treatment, ischemia pressure and post-isometric relaxation reduced shoulder and neck pain and PPT discomfort. This study suggests that ischemia compression may be more effective than post-isometric relaxation for treating rhomboid latent myofascial trigger points (MTP). Future progress in the field will depend on multi-subject RCTs.

BACKGROUND AND OBJECTIVE
Sciatica is a common type of neuropathic pain disease which poses a huge financial burden to the patient. For patients with sciatica, acupuncture has been recommended as an effective method for pain relief, while there is currently a lack of sufficient evidence to support its efficacy and safety. In this review, we aimed to critically assess the published clinical evidence on the efficacy and safety of acupuncture therapy for treating sciatica.
METHODS
An extensive literature search strategy was established in seven databases from their inception to 31 March 2022. Two independent reviewers performed the literature search, identification, and screening. Data extraction was performed on studies that meet the inclusion criteria, and a further quality assessment was performed according to the Cochrane Handbook and Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA) recommendations. Summary Risk ratio (RR) and standardized mean differences (SMDs) with 95% confidence interval (CI) were calculated using the fixed-effects or the random-effects model. Heterogeneity in effect size across studies was explored using the subgroup analysis and the sensitivity analysis. The quality of evidence was estimated following the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach.
RESULTS
A total of 30 randomized controlled trials (RCTs) involving 2,662 participants were included in the meta-analysis. The results of the integration of clinical outcomes showed that the clinical efficacy of acupuncture was superior to that of medicine treatment (MT) in improving the total effective rate (relative risk (RR) = 1.25, 95% confidence interval (CI) [1.21, 1.30]; moderate certainty of evidence), reducing the Visual Analog Scale (VAS) pain score (standardized mean difference (SMD) = -1.72, 95% CI [-2.61, -0.84]; very low certainty of evidence), increasing pain threshold (SMD = 2.07, 95% CI [1.38, 2.75]; very low certainty of evidence), and decreasing recurrence rate (RR = 0.27, 95% CI [0.13, 0.56]; low certainty of evidence). In addition, a few adverse events (RR = 0.38, 95% CI [0.19, 0.72]; moderate certainty of evidence) were reported during the intervention, which indicated that acupuncture was a safe treatment option.
CONCLUSIONS
Acupuncture therapy is an effective and safe treatment for patients with sciatica, and it can be considered a suitable replacement for medicine treatment (MT). However, given the high heterogeneity and a low methodological quality of previous studies, future RCTs should be well-designed according to the rigorous methodology.

Meta-Analysis
BACKGROUND
Patellofemoral pain (PFP) has high recurrence rates and minimal long-term treatment success. Central sensitization refers to dysfunctional pain modulation that occurs when nociceptive neurons become hyperresponsive. Researchers in this area of PFP have been increasingly productive in the past decade.
OBJECTIVE
To determine whether evidence supports manifestations of central sensitization in individuals with PFP.
DATA SOURCES
We searched MeSH terms for quantitative sensory testing (QST) pressure pain thresholds (PPTs), conditioned pain modulation (CPM), temporal summation, sensitization, hyperalgesia, and anterior knee pain or PFP in PubMed, SPORTDiscus, CINAHL, Academic Search Complete, and EBSCOhost.
STUDY SELECTION
Peer-reviewed studies that were written in English and published between 2005 and 2020 and investigated QST or pain mapping in a sample with PFP were included in this review.
DATA EXTRACTION
The initial search yielded 140 articles. After duplicates were removed, 78 abstracts were reviewed. The full text of 21 studies was examined, and we included 15 studies in our evaluation: 6 in the meta-analysis, 4 in the systematic review, and 5 in both the meta-analysis and systematic review.
DATA SYNTHESIS
A random-effects meta-analysis was conducted for 4 QST variables (local PPTs, remote PPTs, CPM, temporal summation). Strong evidence supported lower local and remote PPTs, impaired CPM, and facilitated temporal summation in individuals with PFP compared with pain-free individuals. Evidence for heat and cold pain thresholds was conflicting. Pain mapping demonstrated expanding pain patterns associated with long duration of PFP symptoms.
CONCLUSIONS
Signs of central sensitization were present in individuals with PFP, indicating altered pain modulation. The etiologic and treatment models of PFP should reflect the current body of evidence regarding central sensitization. Signs of central sensitization should be monitored clinically, and treatments with central effects should be considered as part of a multimodal plan of care.

Meta-Analysis
BACKGROUND
Sciatica results from primary or secondary damage to the sciatic nerve in the lumbar or gluteal region. The first option for sciatica is analgesics, but their therapeutic effect and safety in long-term use are questionable. On the other hand, acupuncture has recently been recognized as a complementary and alternative medicine (CAM) to conventional medicine, and studies on its effectiveness and safety have been actively conducted.
OBJECTIVE
To systematically compare acupuncture with analgesics in terms of effect, safety, and durability in the treatment of sciatica METHODS: This review was performed in accordance with Cochrane Handbook for Systematic Reviews of Interventions Version 6.2. Four databases were searched for this review: Wangfang, the Korean Traditional Knowledge Portal (KTKP), PubMed, and EBSCOhost. The primary outcome measures in the review were total effective rate (TER), visual analog scale (VAS) score and pain threshold, and the secondary ones were adverse effects (AEs) and relapse rates. Risk ratio (RR) for TER and mean difference (MD) for VAS score and pain threshold were used as statistics for the meta-analysis of effectiveness, along with associated 95 % confidence intervals (CIs) and P-values. AEs and relapse rates were used for the safety and durability of the interventions. Version 2 of the Cochrane risk-of-bias assessment tool for randomized trials (RoB 2) was used for the methodological quality of randomized controlled trials (RCTs) included in the review.
RESULTS
The synthesized TER of 28 RCTs involving 2707 participants was significantly higher in the acupuncture group compared to the analgesic group (RR [95 % CI] = 1.20 [1.16, 1.24], P < 0.001). The synthesized VAS score of 7 RCTs involving 589 participants was significantly reduced in the acupuncture group compared to the analgesic group (MD [95 % CI] = - 1.78 [- 2.44, - 1.12], P < 0.001). In 5 RCTs involving 311 participants, the synthesized pain threshold was significantly elevated in the acupuncture group compared to the analgesic group (MD [95 % CI] = 0.93 [0.64, 1.22], P < 0.001). Additionally, adverse effects (AEs) and relapse rates of RCTs in the review were lower in the acupuncture group compared to the analgesic group.
CONCLUSION
In this systematic review, acupuncture treatment was significantly effective and safe compared to analgesics in sciatica. In the future, studies with a rigorous study design are required to increase the validity of the effectiveness and safety of acupuncture treatment for sciatica.

Review
OBJECTIVE
The objective of this review was to assess the therapeutic effect of ultrasound (US) on myofascial pain syndrome (MPS).
DATE SOURCES
PubMed, Embase, and Cochrane Library were searched to find relevant studies from January 1966 to May 2016 using keywords. Four investigators performed the data extraction.
STUDY SELECTION
Randomized controlled trials (RCTs) investigating the outcomes of pain and physical function between MPS patients receiving and not receiving US were selected by two researchers independently.
DATA EXTRACTION
Data were extracted from the RCTs. Risk of bias and study quality were evaluated following the recommendations of Cochrane Collaboration. Standardized mean difference (SMD) and 95% confidence interval (CI) were calculated.
DATA SYNTHESIS
A total of 10 studies involving 428 MPS patients were included. US therapy significantly reduced pain intensity (SMD [CI]=-1.41 [-2.15, -0.67], =0.0002) and increased pain threshold (SMD [CI]=1.08 [0.55, 1.60], <0.0001), but had no significant effect on cervical range of motion (ROM) of lateral flexion (SMD [CI]=0.40 [-0.19, 0.99], =0.19), rotation (SMD [CI]=0.10 [-0.33, 0.52], =0.66), or extension or flexion (SMD [CI]=0.16 [-0.35, 0.68], =0.53). Heterogeneity between studies was mainly attributed to differences in the follow-up time, parameter of US, course of treatment, and the control group. The overall risk of bias from the included studies was high, and the evidence proving these effect calculations were assessed as low quality.
CONCLUSION
Owing to the high risk of bias and the across-trial heterogeneity of the studies, the current evidence is not clear enough to support US as an effective method to treat MPS. Clinical trials with methodological rigorousness and adequate power are needed to confirm it in the future.

Fibromyalgia is a chronic pain syndrome characterized by sensorimotor deficits and distortions of body representation, that could both be caused by alterations in sensory processing. Several studies suggest a hypersensitivity to various sensory stimulations in fibromyalgia but results on detection of both noxious and non-noxious tactile stimulation, which are particularly relevant for body representation and motor control, remain conflicting. Therefore, the aim of this study is to systematically review and quantify the detection thresholds to noxious and non-noxious tactile stimuli in individuals with fibromyalgia compared to pain-free controls. A systematic review and a meta-analysis were performed in the MEDLINE, EMBASE, CINAHL, Cochrane, PsycInfo and Web of Science databases using keywords related to fibromyalgia, tactile pain detection threshold, tactile detection threshold and quantitative sensory testing. Nineteen studies were included in the review, with 12 in the meta-analysis. Despite the heterogeneity of the results, the data from both the review and from the meta-analysis suggest a trend toward hyperalgesia and no difference of sensitivity to non-noxious tactile stimuli in participants with fibromyalgia compared to healthy controls. This contradicts the hypothesis of a general increase in responsiveness of the central nervous system to noxious and non-noxious stimulations in fibromyalgia. This study shows no alteration of the sensitivity to non-noxious tactile stimulation in fibromyalgia, suggesting that an altered unimodal processing is not sufficient to explain symptoms such as sensorimotor impairments and body representation distortions. Future research should investigate whether alterations in multisensory integration could contribute to these symptoms.

Meta-Analysis
INTRODUCTION
The initiation of the extracorporeal membrane oxygenation (ECMO) is associated with complex coagulatory and inflammatory processes and consequently needed anticoagulation. Systemic anticoagulation bears an additional risk of serious bleeding, and its monitoring is of immense importance. Therefore, our work aims to analyze the association of anticoagulation monitoring with bleeding during ECMO support.
MATERIAL AND METHODS
Systematic literature review and meta-analysis, complying with the PRISMA guidelines (PROSPERO-CRD42022359465).
RESULTS
Seventeen studies comprising 3249 patients were included in the final analysis. Patients experiencing hemorrhage had a longer activated partial thromboplastin time (aPTT), a longer ECMO duration, and higher mortality. We could not find strong evidence of any aPTT threshold association with the bleeding occurrence, as less than half of authors reported a potential relationship. Finally, we identified the acute kidney injury (66%, 233/356) and hemorrhage (46%, 469/1046) to be the most frequent adverse events, while almost one-half of patients did not survive to discharge (47%, 1192/2490).
CONCLUSION
The aPTT-guided anticoagulation is still the standard of care in ECMO patients. We did not find strong evidence supporting the aPTT-guided monitoring during ECMO. Based on the weight of the available evidence, further randomized trials are crucial to clarify the best monitoring strategy.

BACKGROUND
Mortality, morbidity, and organ failure are important and common serious harms after surgery. However, there are many candidate measures to describe these outcome domains. Definitions of these measures are highly variable, and validity is often unclear. As part of the International Standardised Endpoints in Perioperative Medicine (StEP) initiative, this study aimed to derive a set of standardised and valid measures of mortality, morbidity, and organ failure for use in perioperative clinical trials.
METHODS
Three domains of endpoints (mortality, morbidity, and organ failure) were explored through systematic literature review and a three-stage Delphi consensus process using methods consistently applied across the StEP initiative. Reliability, feasibility, and patient-centredness were assessed in round 3 of the consensus process.
RESULTS
A high level of consensus was achieved for two mortality time points, 30-day and 1-yr mortality, and these two measures are recommended. No organ failure endpoints achieved threshold criteria for consensus recommendation. The Clavien-Dindo classification of complications achieved threshold criteria for consensus in round 2 of the Delphi process but did not achieve the threshold criteria in round 3 where it scored equivalently to the Post Operative Morbidity Survey. Clavien-Dindo therefore received conditional endorsement as the most widely used measure. No composite measures of organ failure achieved an acceptable level of consensus.
CONCLUSIONS
Both 30-day and 1-yr mortality measures are recommended. No measure is recommended for organ failure. One measure (Clavien-Dindo) is conditionally endorsed for postoperative morbidity, but our findings suggest that no single endpoint offers a reliable and valid measure to describe perioperative morbidity that is not dependent on the quality of deli-vered care. Further refinement of current measures, or development of novel measures, of postoperative morbidity might improve consensus in this area.
