Meta-Analysis Review
BACKGROUND
The Zadek osteotomy, a dorsal closing wedge osteotomy of the calcaneus, has been described as a treatment option in patients with Insertional Achilles Tendinopathy (IAT) that have failed conservative management. The aim of this study was to evaluate the clinical outcomes and the complications of the Zadek for the management of IAT.
METHODS
PubMed, EMBASE and Cochrane Central Register of Controlled Trails (CENTRAL) were searched for all studies to November 2022. PRISMA guidelines were followed. The overall estimates of effect were presented as Weighted Mean Difference (WMD) and 95 % confidence intervals (CIs). Meta-analysis was conducted using the Review Manager Software (RevMan, Version 5.4).
RESULTS
Ten studies with 232 patients were included. Functional scores and pain levels were significantly improved after the Zadek osteotomy (p < 0.00001). There were a total of 22 complications reported in the included studies and they were all considered minor. The most common complications were superficial wound infection and sural nerve paraesthesia.
CONCLUSIONS
The Zadek osteotomy is a safe and effective procedure for patients with IAT. There are no well-designed randomized controlled trials in the literature assessing the outcomes of a Zadek osteotomy against alternate surgical treatments and future research should focus on this.

Review
OBJECTIVE
Dorsal root ganglion (DRG) has recently emerged as an attractive target for neuromodulation therapy since primary sensory neurons and their soma in DRGs are important sites for pathophysiologic changes that lead to neuropathic pain. Our aim was to create evidence synthesis about the effects of electrical stimulation of DRG in the context of pain from in vitro and in vivo animal models, analyze methodology and quality of studies in the field.
METHODS
For conducting systematic review we searched three data bases: MEDLINE, Embase and Web of Science. The quality of included studies was assessed with the Systematic Review Centre for Laboratory Animal Experimentation risk of bias tool for animal studies. The study was registered in the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies data base.
RESULTS
We included six in vitro and eight in vivo animal studies. All included in vitro studies combined neurostimulation with substances or drugs and reported an improvement in pain-related parameters due to neurostimulation. Among in vivo studies, six used pulsed radiofrequency, while two used electrical field stimulation. All in vivo studies reported improvement in pain-related behavior following stimulation. Meta-analysis was not possible because of heterogeneity and missing data. The quality of included studies was suboptimal since all had an unclear risk of bias in multiple domains.
CONCLUSIONS
Limited data from in vitro and in vivo animal studies indicate that electrical stimulation of DRG has a positive therapeutic effect in the context of pain-related outcomes. Further studies with a standardized methodological approach and outcomes will provide useful information about electrical stimulation of DRG in animal models.

Meta-Analysis
BACKGROUND
Distally based dorsal metacarpal flaps for the reconstruction of finger soft-tissue defects are classified into 3 categories: dorsal metacarpal artery perforator flap, reverse dorsal metacarpal artery (RDMA) flap, and extended reverse dorsal metacarpal artery (ERDMA) flap. The present systematic review aimed to evaluate differences in the outcomes of commonly encountered defects and postoperative complications among these three flaps.
METHODS
PubMed, Scopus, and Web of Science were systematically searched from when the flats were first reported to May 2021. Random-effects meta-analysis for each outcome was performed, and 24 studies were included in the analysis.
RESULTS
Dorsal metacarpal artery perforator flaps were mainly used for defects extending to the proximal interphalangeal joint (n = 62 [29.1%]) and proximal phalanx (n = 85 [39.9%]). Conversely, defects extending to the distal phalanx (n = 24 [43.6%]) were mostly reconstructed using the ERDMA flap. The rate of venous congestion was highest for the ERDMA flap (29.3%; 95% confidence interval [CI], -17.2% to 65.1%; I2 = 0%) and lowest for RDMA flap (8.1%; 95% CI, -5.9% to 21.7%; I2 = 0%). The RDMA flap showed the lowest rate of any short-term complications, including partial and total necrosis (6.6%; 95% CI, -6.8% to 19.8%; I2 = 0%).
CONCLUSIONS
This systematic review demonstrated that the dorsal metacarpal artery perforator flap was suitable for reconstruction proximal to the middle phalanx, and the ERDMA flap was suitable for reconstruction distal to the distal interphalangeal joint. Although the RDMA flap showed the lowest rate of short-term complications and limited analysis was secondary to limited data available, these occurred in 6.6% to 10.9% of distally based dorsal metacarpal flaps.

Review
Both substance-related as well as non-substance-related addictions may include recurrent engagement in risky actions despite adverse outcomes. We here apply a unified approach and review task-based neuroimaging studies on substance-related (SRAs) and non-substance related addictions (NSRAs) to examine commonalities and differences in neural correlates of risk-taking in these two addiction types. To this end, we conducted a systematic review adhering to the PRISMA guidelines. Two databases were searched with predefined search terms to identify neuroimaging studies on risk-taking tasks in individuals with addiction disorders. In total, 19 studies on SRAs (comprising a total of 648 individuals with SRAs) and 10 studies on NSRAs (comprising a total of 187 individuals with NSRAs) were included. Risk-related brain activation in SRAs and NSRAs was summarized individually and subsequently compared to each other. Results suggest convergent altered risk-related neural processes, including hyperactivity in the OFC and the striatum. As characteristic for both addiction types, these brain regions may represent an underlying mechanism of suboptimal decision-making. In contrast, decreased DLPFC activity may be specific to SRAs and decreased IFG activity could only be identified for NSRAs. The precuneus and posterior cingulate show elevated activity in SRAs, while findings regarding these areas were mixed in NSRAs. Additional scarce evidence suggests decreased ventral ACC activity and increased dorsal ACC activity in both addiction types. Associations between identified activation patterns with drug use severity underpin the clinical relevance of these findings. However, this exploratory evidence should be interpreted with caution and should be regarded as preliminary. Future research is needed to evaluate the findings gathered by this review.

Review
Parvalbumin is one of the calcium-binding proteins. In the spinal cord, it is mainly expressed in inhibitory neurons; in the dorsal root ganglia, it is expressed in proprioceptive neurons. In contrast to in the brain, weak systematization of parvalbumin-expressing neurons occurs in the spinal cord. The aim of this paper is to provide a systematic review of parvalbumin-expressing neuronal populations throughout the spinal cord and the dorsal root ganglia of mammals, regarding their mapping, co-expression with some functional markers. The data reviewed are mostly concerning rodentia species because they are predominantly presented in literature.

Meta-Analysis Review
UNLABELLED
The aim of this study was to perform a systematic review in order to identify predictors of secondary displacement in distal radius fractures. We performed a systematic review and identified all studies that reported secondary displacement following distal radius fractures. Where possible, we pooled the odds ratios of predictors. The initial search yielded 3178 studies of which 27 were included. Multiple studies found that age, shortening, volar comminution, loss of radial inclination, the presence of a volar hook, AO type 3 fractures (A3, B3, C3) and the Older classification were significant predictors of secondary displacement. Pooling revealed a significantly increased risk of secondary displacement in fractures with dorsal comminution, in women and in patients aged >60 years. An associated ulna fracture or intra-articular involvement does not result in an increased risk of secondary displacement. The overview provided in this study can help surgeons to inform patients of the chances of success of closed treatment regarding the radiological outcome and facilitate shared decision making.

Meta-Analysis
BACKGROUND
Premature ejaculation is a common sexual dysfunction disease in adult males. There are many clinical trials shown that dorsal penile nerve block can prolong the ejaculation latency to a certain extent in the vagina. In this study, we aim to use a meta-analysis to evaluate the efficacy and safety of dorsal penile nerve block for premature ejaculation.
METHODS AND ANALYSIS
We will search for PubMed, Cochrane Library, AMED, EMbase, WorldSciNet, Nature, Science online and China Journal Full-text Database (CNKI), China Biomedical Literature CD-ROM Database (CBM), and related randomized controlled trials included in the China Resources Database. The time is limited from the construction of the library to February 2019. The quality of the included RCTs will be evaluated with the risk of bias (ROB) tool and evidence will be evaluated by GRADE. Data analysis will be used the special software like RevMan (version 5.3) and EndNote X7.
RESULTS
The results of this meta-analysis will be submitted to a peer-reviewed journal for publication.
ETHICS AND DISSEMINATION
This systematic review will evaluate the efficacy and safety of dorsal penile nerve block for premature ejaculation. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process Trial.

Review
UNLABELLED
We assessed the proximity of neurological structures to arthroscopic portals in a cadaveric study and through a systematic review. Arthroscopy was performed on ten cadaveric wrists. Subsequently the specimens were dissected to isolate the superficial branch of the radial nerve, the dorsal branch of the ulnar nerve, the posterior interosseous nerve and the extensor tendons. We measured the distances from the nerves to common portals. For the systematic review Pubmed and EMBASE were searched on the 31 May 2014 for cadaveric studies reporting the proximity of neurological structures to any arthroscopic wrist portal. In the cadaveric study, partial injuries were seen to six extensor tendons and one posterior interosseous nerve; it was assumed this was due to creation of the portals. Seven published studies were included in the systematic review. The dorsal sensory branch of the ulnar nerve was found to be at risk by performing the 6 Ulnar, 6 Radial and ulnar midcarpal portals, the sensory branch of the radial nerve by the 1-2 and 3-4 portals and the posterior interosseous nerve by the 3-4 and 4-5 portals.

Review
Several animal and human studies revealed that joint and nerve mobilisations positively influence neuroimmune responses in neuromusculoskeletal conditions. However, no systematic review and meta-analysis has been performed. Therefore, this study aimed to synthesize the effects of joint and nerve mobilisation compared with sham or no intervention on neuroimmune responses in animals and humans with neuromusculoskeletal conditions. Four electronic databases were searched for controlled trials. Two reviewers independently selected studies, extracted data, assessed the risk of bias, and graded the certainty of the evidence. Where possible, meta-analyses using random effects models were used to pool the results. Preliminary evidence from 13 animal studies report neuroimmune responses after joint and nerve mobilisations. In neuropathic pain models, meta-analysis revealed decreased spinal cord levels of glial fibrillary acidic protein, dorsal root ganglion levels of interleukin-1β, number of dorsal root ganglion nonneuronal cells, and increased spinal cord interleukin-10 levels. The 5 included human studies showed mixed effects of spinal manipulation on salivary/serum cortisol levels in people with spinal pain, and no significant effects on serum β-endorphin or interleukin-1β levels in people with spinal pain. There is evidence that joint and nerve mobilisations positively influence various neuroimmune responses. However, as most findings are based on single studies, the certainty of the evidence is low to very low. Further studies are needed.

Review
While there is evidence of clinical improvement of posttraumatic stress disorder (PTSD) with treatment, its neural underpinnings are insufficiently clear. Moreover, it is unknown whether similar neurophysiological changes occur in PTSD specifically after child abuse, given its enduring nature and the developmental vulnerability of the brain during childhood. We systematically reviewed PTSD treatment effect studies on structural and functional brain changes from PubMed, EMBASE, PsycINFO, PILOTS and the Cochrane Library. We included studies on adults with (partial) PTSD in Randomized Controlled Trials (RCT) or pre-post designs (excluding case studies) on pharmacotherapy and psychotherapy. Risk of bias was evaluated independently by two raters. Brain coordinates and effect sizes were standardized for comparability. We included 15 studies (6 RCTs, 9 pre-post), four of which were on child abuse. Results showed that pharmacotherapy improved structural abnormalities (i.e., increased hippocampus volume) in both adult-trauma and child abuse related PTSD (3 pre-post studies). Functional changes were found to distinguish between groups. Adult-trauma PTSD patients showed decreased amygdala and increased dorsolateral prefrontal activations post-treatment (4 RCTs, 5 pre-post studies). In one RCT, child abuse patients showed no changes in the amygdala, but decreased dorsolateral prefrontal, dorsal anterior cingulate and insula activation post-treatment. In conclusion, pharmacotherapy may reduce structural abnormalities in PTSD, while psychotherapy may decrease amygdala activity and increase prefrontal, dorsal anterior cingulate and hippocampus activations, that may relate to extinction learning and re-appraisal. There is some evidence for a distinct activation pattern in child abuse patients, which clearly awaits further empirical testing.
