Lateral epicondylitis, also termed as “tennis elbow,” is the most common cause of elbow pain and dysfunction, mainly resulting from repetitive gripping or wrist extension during various activities. The exact pathogenesis remains largely elusive with putative tendinosis, a symptomatic degenerative process of the local tendon. It is usually diagnosed by clinical examinations. Sometimes, additional imaging is required for a specific differential diagnosis. Although most cases can be self-healing, the optimal treatment strategy for chronic lateral epicondylitis remains controversial. This article presents a landscape of emerging evidence on lateral epicondylitis and focuses on the pathogenesis, diagnosis, and management, shedding light on the understandings and treatment for healthcare professionals.

Chronic non-specific low back pain (NLBP) affects people of all ages and pose a serious threat to human health. Fu's subcutaneous needling (FSN) has been reported to be effective in treating such disorders, but the control group is lacking. The aim of this randomized parallel study is to compare the long-term efficiency of FSN therapy with massage therapy for treatment of NLBP.A total of 60 chronic NLBP patients recruited from Yongchuan Hospital of Chongqing Medical University were randomly assigned to the FSN therapy group or massage therapy group. The main prognostic indicators included pain intensity measured on the visual analog scale (VAS), functional outcomes assessed by the Japanese Orthopedic Association (JOA) scoring system, functional disability estimated using Oswestry Disability Index (ODI), and quality of life evaluated by Short Form Health Survey Questionnaire (SF-36). These indicators were evaluated at baseline, post-treatment, 3 months after treatment, and 12 months after treatment.After 12 months of follow-up, we found that the 2 treatment regimens exhibited similarly favorable results in terms of all prognostic indicators in comparison with their respective baseline data (all P0.01). However, compared with the massage group, the FSN group showed more significant improvements in VAS, JOA, and ODI at all follow-up time points, as well as SF-36 at post-treatment and 12 months after treatment (all P0.05).Our findings suggest that FSN therapy is significantly more effective than massage therapy in the improvement of pain intensity, functional outcomes, functional disability, and quality of life in a long-term follow-up. However, future studies with larger sample sizes are needed to corroborate the long-term efficiency of FSN therapy for chronic NLBP.Chinese Clinical Trial Registry ChiCTR2100050866.

(1) Background: The efficiency of balneotherapy (BT) for fibromyalgia syndrome (FMS) remains elusive. (2) Methods: Cochrane Library, EMBASE, MEDLINE, PubMed, Clinicaltrials.gov, and PsycINFO were searched from inception to 31 May 2020. Randomized controlled trials (RCTs) with at least one indicator were included, i.e., pain, Fibromyalgia Impact Questionnaire (FIQ), Tender Points Count (TPC), and Beck’s Depression Index (BDI). The outcome was reported as a standardized mean difference (SMD), 95% confidence intervals (CIs), and I2 for heterogeneity at three observational time points. GRADE was used to evaluate the strength of evidence. (3) Results: Amongst 884 citations, 11 RCTs were included (n = 672). Various BT regimens were reported (water types, duration, temperature, and ingredients). BT can benefit FMS with statistically significant improvement at different time points (pain of two weeks, three and six months: SMD = −0.92, −0.45, −0.70; 95% CI (−1.31 to −0.53, −0.73 to −0.16, −1.34 to −0.05); I2 = 54%, 51%, 87%; GRADE: very low, moderate, low; FIQ: SMD = −1.04, −0.64, −0.94; 95% CI (−1.51 to −0.57, −0.95 to −0.33, −1.55 to −0.34); I2 = 76%, 62%, 85%; GRADE: low, low, very low; TPC at two weeks and three months: SMD = −0.94, −0.47; 95% CI (−1.69 to −0.18, −0.71 to −0.22); I2 = 81%, 0; GRADE: very low, moderate; BDI at six months: SMD = −0.45; 95% CI (−0.73 to −0.17); I2 = 0; GRADE: moderate). There was no statistically significant effect for the TPC and BDI at the remaining time points (TPC at six months: SMD = −0.89; 95% CI (−1.85 to 0.07); I2 = 91%; GRADE: very low; BDI at two weeks and three months: SMD = −0.35, −0.23; 95% CI (−0.73 to 0.04, −0.64 to 0.17); I2 = 24%, 60%; GRADE: moderate, low). (4) Conclusions: Very low to moderate evidence indicates that BT can benefit FMS in pain and quality-of-life improvement, whereas tenderness and depression improvement varies at time phases. Established BT regimens with a large sample size and longer observation are needed.

ImportanceSARS-CoV-2 is associated with multiple direct and indirect effects to the heart. It is not yet well defined whether patient groups at increased risk of severe respiratory disease due to SARS-CoV-2 infection also experience a heightened incidence of cardiac complications.ObjectiveWe sought to analyse the role of pre-existing chronic disease (chronic respiratory illness, cardiovascular disease (CVD), hypertension and diabetes mellitus) in the development of cardiac complications from SARS-CoV-2.Data SourcesWe retrospectively investigated published (including pre-prints), publicly released, de-identified, data made available between Dec 1, 2019, and May 11, 2020. Information was accessed from PubMed, Embase, medRxiv and SSRN.Study Selection379 full-text articles were reviewed and 321 excluded for lack of original research, irrelevance to outcome, inappropriate cohort, or small patient numbers (case reports of Data Extraction and SynthesisThis systematic review was conducted based on PRISMA and MOOSE statements. Included studies were critically appraised using Newcastle Ottawa Quality Assessment Scale (NOS). Data were extracted independently by multiple observers. A fixed-effects model was selected for the meta-analysis based on relatively low heterogeneity between the studies (I2Main Outcome and MeasuresCardiac complications were determined via blood levels of cardiac biomarkers above the 99thpercentile of the upper reference limit, abnormalities in electrocardiography, and/or abnormalities in echocardiography.ResultsSARS-CoV-2-infected patients who developed cardiac complications were, on average, 10 years older than those that did not. Pooled analyses showed the development of cardiac complications from SARS-CoV-2 was significantly increased in patients with underlying chronic respiratory illness (OR 2.88[1.45,5.71]), CVD (OR 5.12[3.09,8.48]), hypertension (OR 4.37[2.99,6.39]) and diabetes mellitus (OR 2.61[1.67,4.09]).Conclusions and RelevanceOlder age and pre-existing chronic respiratory illness, CVD, hypertension, and diabetes mellitus may represent prognostic factors for the development of additional cardiac complications in COVID-19, highlighting the need for a multidisciplinary approach to chronic disease patient management and providing justification for a larger scale observational study.

BackgroundNotwithstanding the clinical hallmarks of COVID-19 patients were reported, several critical issues still remain mysterious, i.e., prognostic factors for COVID-19 including extrinsic factors as viral load of SARS-CoV-2 and intrinsic factors as individual’s health conditions; myocarditis incidence rate and hallmarks.MethodsDemographic, epidemiologic, radiologic and laboratory data were collected by medical record reviews of adult hospitalized patients diagnosed as COVID-19. Cycle threshold (Ct) value data of real-time PCR (RT-PCR) were collected. The time duration was from 21 January to 2 March, 2020. Pulmonary inflammation index (PII) values were used for chest CT findings. Multivariate logistic regression analysis was used to identify independent severity risk factors.RESULTSIn total, 84 hospitalized adult patients diagnosed as COVID-19 were included, including 20 severe and 64 nonsevere cases. The viral load of the severe group was significantly higher than that of the non-severe group, regardless of the Ct values forNorORF1abgene of virus (all pInterpretationThree key-independent risk factors of COVID-19 were identified, including age, PII, and Ct value. The Ct value is closely correlated with the severity of COVID-19, and may act as a predictor of clinical severity of COVID-19 in the early stage. SARS-CoV-2 myocarditis should be highlighted despite a relatively low incidence rate (4.8%). The oxygen pressure and blood oxygen saturation should not be neglected as closely linked with the altitude of epidemic regions.Research in contextEvidence before this studyWe searched Pubmed on March 15, 2020 using the terms (“COVID-19” OR “novel coronavirus” OR “2019 novel coronavirus” OR “2019-nCoV” OR “pneumonia” OR “coronavirus”), AND “Myocarditis” OR “Cycle threshold (Ct)” OR “Altitude”. We found that one article analyzed the risk factors affecting the prognosis of adult patients with COVID-19 in terms of survivorship, without considering Ct values as extrinsic factors. Moreover, there are no reported studies on viral myocarditis caused by COVID-19 and the relationship between the altitude and COVID-19.Added value of this studyWe retrospectively analyzed the clinical data, Ct values, laboratory indicators and imaging findings of 84 adult patients with confirmed COVID-19. Three key-independent risk factors of COVID-19 were identified in our study, including age [OR 2.350; 95% CI (1.206 to 4.580); p=0.012], Ct value [OR 0.158; 95% CI (0.025 to 0.987); p=0.048] and PII [OR 1.912; 95% CI (1.187 to 3.079); p=0.008]. Amongst 84 patients, 13 patients (15.48%) were noted with abnormal electrocardiograms (ECGs) and serum myocardial enzyme levels; whereas 4 (4.8%) were clinically diagnosed as SARS-CoV-2 myocarditis. Moreover, altitude should be considered for COVID-19 severity classification, given that oxygen partial pressure and blood oxygen saturation of regional patients vary with altitudes.Implications of all the available evidenceThree key-independent risk factors of COVID-19 were identified, including age, PII, and Ct value. The Ct value is closely correlated with the severity of COVID-19, and may act as a predictor of clinical severity of COVID-19 in the early stage. SARS-CoV-2 myocarditis should be highlighted despite a relatively low incidence rate (4.8%). The oxygen pressure and blood oxygen saturation should not be neglected as closely linked with the altitude of epidemic regions.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been associated with multiple direct and indirect cardiovascular complications. We sought to analyze the association of host co-morbidities (chronic respiratory illnesses, cardiovascular disease [CVD], hypertension or diabetes mellitus [DM]) with the acute cardiovascular complications associated with SARS-CoV-2 infection. Individual analyses of the majority of studies found median age was higher by ~10 years in patients with cardiovascular complications. Pooled analyses showed development of SARS-CoV-2 cardiovascular complications was significantly increased in patients with chronic respiratory illness (odds ratio (OR): 1.67 [1.48, 1.88]), CVD (OR: 3.37 [2.57, 4.43]), hypertension (OR: 2.68 [2.11, 3.41]), DM (OR: 1.60 [1.31, 1.95]) and male sex (OR: 1.31 [1.21, 1.42]), findings that were mostly conserved during sub-analysis of studies stratified into global geographic regions. Age, chronic respiratory illness, CVD, hypertension, DM, and male sex may represent prognostic factors for the development of cardiovascular complications in COVID-19 disease, highlighting the need for a multidisciplinary approach to chronic disease patient management., Graphical abstract, Virology; Omics
