RESUMO
Temporomandibular joint disorders (TMD) generate pain and difficulties for mouth opening affecting the patients' quality of life. Ozone is an emerging therapy that has been proposed as a potential treatment, due to that, the evidence about its efficacy should be reviewed. Therefore, this work aimed to conduct a comprehensive systematic review to address the efficacy of ozone therapy for the treatment of pain and limited mouth opening in patients with TMD. The design of the included studies was clinical trials and observational studies, whereas, a series of cases, in vivo, and in vitro studies were excluded. The search was performed in PubMed, ClinicalTrials, Web of Science, and Scopus. Gray literature was searched at Google Scholar. Relevant data of all included studies were recorded. The risk of bias (using RoB 2) and the quality (using Grading of Recommendations Assessment, Development, and Evaluation) assessments were carried out. Meta-analyses using random-effects models of pain and maximal mouth opening data were performed. This review included 8 studies with 404 participants suffering limited function and pain related to TMD. At the overall bias of the studies, 25% exhibited some concerns and 75% had high risk; and the quality of the studies was low. The analysis of the included studies suggests that ozone therapy can diminish pain and improve the maximal mouth opening in TMD patients. However, there is no conclusive evidence of ozone therapy as a superior treatment for TMD compared with occlusal splint and pharmacotherapy.

This systematic review aimed to compare the efficacy of nonpharmacological therapies for painful temporomandibular joint disorders. The protocol was registered on International Prospective Register of Systematic Reviews (PROSPERO) database (CRD42020171364). The search was performed on the electronic databases PubMed, Google Scholar, Clinical Trials, and Web of Science. The eligibility criteria were randomized controlled trials in patients diagnosed with painful temporomandibular joint disorders comparing the pain relief between conventional treatment and nonpharmacological therapies such as acupuncture, physiotherapy, low-level laser, and massage. Fourteen articles were included in this review. At the overall bias of the studies included, 71.42% exhibited some concerns and 28.57% had high risk. The efficacy of nonpharmacological interventions was found to be moderate in the short term and variable in the long term for pain reduction in patients with temporomandibular joint disorders. The evidence pointed out that acupuncture, laser therapy, and physiotherapy are potentially useful interventions for pain relief in patients with temporomandibular joint disorders. However, there is a lack of consistency and short-term follow-up in the studies to determine the lasting of such effect.
RESUMO
BACKGROUND: The assessment of motor function is vital in post-stroke rehabilitation protocols, and it is imperative to obtain an objective and quantitative measurement of motor function. There are some innovative machine learning algorithms that can be applied in order to automate the assessment of upper extremity motor function. OBJECTIVES: To perform a systematic review and meta-analysis of the efficacy of machine learning algorithms for assessing upper limb motor function in post-stroke patients and compare these algorithms to clinical assessment. MATERIAL AND METHODS: The protocol was registered in the International Prospective Register of Systematic Reviews (PROSPERO) database. The review was carried out according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Interventions. The search was performed using 6 electronic databases. The meta-analysis was performed with the data from the correlation coefficients using a random model. RESULTS: The initial search yielded 1626 records, but only 8 studies fully met the eligibility criteria. The studies reported strong and very strong correlations between the algorithms tested and clinical assessment. The meta-analysis revealed a lack of homogeneity (I2 = 85.29%, Q = 48.15), which is attributable to the heterogeneity of the included studies. CONCLUSION: Automated systems using machine learning algorithms could support therapists in assessing upper extremity motor function in post-stroke patients. However, to draw more robust conclusions, methodological designs that minimize the risk of bias and increase the quality of the methodology of future studies are required.

BACKGROUND: Activation of the sympathetic nervous system attenuates inflammation via catecholamines. Recent evidence has shown that electroacupuncture (EA) activates neuronal networks involved in the release of dopamine and norepinephrine that control systemic inflammation. In muscle, catecholamines are related to cyclic adenosine monophosphate (cAMP). This signaling molecule has been implicated in recovery from sustained contractile activity, which may induce muscular pain, such as that which occurs during low back pain (LBP). OBJECTIVE: Our aim was to evaluate the effects of EA used for the control of LBP on the activation of the sympathetic nervous system in a randomized controlled clinical trial in athletes. METHODS: Two groups of athletes with acute or chronic low back pain were studied. EA, sham EA and pharmacological treatment (diclofenac sodium) were evaluated. The outcome measures included a pain score represented by a visual analogue scale (VAS) and serum levels of catecholamines quantified by enzyme-linked immunosorbent assay. In addition, blood was collected into chilled heparin tubes, placed in 96-well cell culture plates and incubated with an equal volume of Roswell Park Memorial Institute (RPMI) medium, with lipopolysaccharide (LPS) alone or with catecholamines. Tumor necrosis factor (TNF)-α levels in the supernatants were analyzed. RESULTS: The results indicated that the initial pain ratings did not differ between the groups analyzed. EA induced epinephrine secretion but not norepinephrine or dopamine secretion. Although EA and pharmacological treatment did not differ in terms of pain relief, in vitro epinephrine and norepinephrine reduced TNF-α production in response to LPS stimuli. CONCLUSION: EA activates the sympathetic nervous system and induces the release of epinephrine, which could ameliorate inflammation and protect muscular tissue in addition to relieving pain.

The first pandemic of the 21st century occurred in 2009 and was caused by the H1N1pdm influenza A virus. Severe cases of H1N1pdm infection in adults are characterized by sustained immune activation, whereas pregnant women are prone to more severe forms of influenza, with increased morbi-mortality. During the H1N1pdm09 pandemic, few studies assessed the immune status of infected pregnant women. The objective of this study was to evaluate the behavior of several immune markers in 13 H1N1pdm2009 virus-infected pregnant (PH1N1) women, in comparison to pregnant women with an influenza-like illness (ILI), healthy pregnant women (HP) and healthy non-pregnant women (HW). The blood leukocyte phenotypes and the serological cytokine and chemokine concentrations of the blood leukocytes, as measured by flow cytometry, showed that the CD69+ cell counts in the T and B-lymphocytes were significantly higher in the PH1N1 group. We found that pro-inflammatory (TNF-α, IL-1ß, IL-6) and anti-inflammatory (IL-10) cytokines and some chemokines (CXCL8, CXCL10), which are typically at lower levels during pregnancy, were substantially increased in the women in the ILI group. Our findings suggest that CD69 overexpression in blood lymphocytes and elevated levels of serum cytokines might be potential markers for the discrimination of H1N1 disease from other influenza-like illnesses in pregnant women.
