Abstract Background: Fibromyalgia (FM) is a common chronic pain condition that seriously affects the quality of patient lives. Its etiology, pathogenesis, and treatment still remain uncertain. Dietary supplements have been widely trialed for symptom relief for FM. The review aims to synthesize the previous literature publications to assess the impact of herbs and dietary supplements on FM patients. Methods: We will conduct a literature search in the following databases PubMed, MEDLINE, EMBASE, Cochrane Library, Scopus, and Global Health from database inception to December 2019. Clinical studies published in the English language that used human participants and address the efficacy, safety, and acceptability of herbs and dietary supplements on individuals with FM will be included. The risk of bias and quality assessment of each trial will be evaluated. If trials are enough, a meta-analysis will be conducted using software RevMan5.3, Cochrane Collaboration. Result: Our review will be the first attempt to facilitate evidence-based management using herbs and dietary supplements to treat patients with FM. Conclusion: The findings may provide a framework for future research and clinic practice in FM management. PROSPERO registration number: CRD42020149941

Objective: Laser acupuncture has become increasingly attractive in clinical practice, especially for patients with needle phobias well as elderly people and children. However, literature concerning the safety of laser acupuncture has been limited. This systematic review synthesizes the current available literature on the safety of laser acupuncture. Methods: Ovid MEDLINE, ® Epub Ahead of Print, In-Process & Other Non-Indexed Citations Daily, Ovid Embase, Scopus, and EBM Reviews—Cochrane Central Register of Controlled Trials databases were searched for available randomized controlled trials (RCTs) on laser acupuncture. Safety data were extracted from the included studies. Adverse events (AEs) data were extracted and assessed in terms of severity and causality. Results: Of 737 articles, 21 RCTs were included. The majority of these RCTs reported that laser acupuncture was safe, without AEs; 6 trials reported AEs (including tingling, pain flare-ups, and transient fatigue). All AEs were mild and resolved spontaneously within 24 hours. The causal relationship between AEs and laser acupuncture was felt to be “certain” in 4 studies, “probable” in 1 study, and “possible” in 1 study. AEs were collected and monitored by evaluation methods in 7 trials: 5 with AE questionnaires, 1 with a checklist, and 1 with oral reports. Conclusions: Laser acupuncture appears to be a safe therapy associated with few mild and transient AEs. However, given the heterogeneity of current studies, large, well-designed placebo-controlled RCTs with rigorous evaluation methods are needed to assess the safety of laser acupuncture more completely.

Abstract Background The term arterial stiffness (ArSt) describes the reduced capability of an artery to expand and contract in response to pressure changes and is recognized as an independent predictor of cardiovascular diseases (CVD). The evidence relating ArSt and triglycerides (TG) shows contradictory results. The aim of this paper is to assess the association between high TG and ArSt, using the cardio-ankle vascular index (CAVI).Methods Subjects aged between 25 and 64 years from a random population-based sample were evaluated between 2013–2016. Data from questionnaires, blood pressure, anthropometric measures and blood samples were collected to identify the metabolic syndrome (MetS). CAVI was measured using VaSera VS-1500N devise (Fukuda Denshi Co., Ltd., Japan). Subjects with history of CVD or chronic renal disease were excluded.Results 1934 participants, 44.7% males, were included. Median age was 48 (Interquartile Range [IQR] 19) years, TG levels were 1.05 (0.793) mmol/L, and CAVI 7.24 (1.43) points. Prevalence of high CAVI was 10.0% (14.5% in males and 6.4% in females; p < 0.001). Correlation between TG and CAVI was 0.136 (p < 0.001). High CAVI values were more prevalent among participants with MetS, high blood pressure, dysglycemia, abdominal obesity, and high total cholesterol. Using binary regression analysis, high TG were associated with high CAVI, even after adjustment for other MetS components, age, gender, smoking status and cholesterol (OR = 1.630, 95% CI = 1.061–2.505, p = 0.026).Conclusion TG levels were correlated with ArSt, measured as CAVI. High TG was associated with high CAVI independent of multiple cardiometabolic risk factors.

Background – The impact of post-operative complications on long-term survival is not well characterized. We sought to study the prevalence of post-operative complications after cardiac surgery and their impact on long-term survival. Methods – Operative survivors (n=26,221) who underwent coronary artery bypass grafting (CABG) (n=13054, 49.8%), valve surgery (n=8667, 33.1%) or combined CABG and valve surgery (n=4500, 17.2%) from 1993 to 2019 were included in the study. Records were reviewed for post-operative complications and long-term survival. The associations between post-operative complications and survival were assessed using a Cox-proportional model. Results – Complications occurred in 17,463 (66.6%) of 26,221 operative survivors. A total of 17 post-operative complications were analyzed. Post-operative blood product use was the commonest (n=12397, 47.3%), followed by atrial fibrillation (n=8399, 32.0%), prolonged ventilation (n=2336, 8.9%), renal failure (n=870, 3.3%), re-operation for bleeding (n=859, 3.3%) and pacemaker/ICD insertion (n=795, 3.0%). Stroke (HR 1.55, 95%CI 1.36-1.77), renal failure (HR 1.45, 95% CI 1.33-1.58) anticoagulant-related events (HR 1.26, 95%CI 1.02-1.56) and pneumonia (HR 1.23, 95%CI 1.11-1.36) had the strongest impact on long-term survival. Long-term survival decreased as the number of post-operative complications increased. Conclusions – Post-operative complications after cardiac surgery significantly impact outcomes that extend beyond the post-operative period. The presence, number and type of post-operative complications adversely impact long-term survival. Stroke, renal failure, anticoagulant-related events and pneumonia are particularly associated with poor long-term survival.

Abstract Purpose: To quantitatively predict the impact of cardiopulmonary dose on overall survival (OS) after radiotherapy for locally advanced non–small cell lung cancer. Experimental Design: We used the NRG Oncology/RTOG 0617 dataset. The model building procedure was preregistered on a public website. Patients were split between a training and a set-aside validation subset (N = 306/131). The 191 candidate variables covered disease, patient, treatment, and dose-volume characteristics from multiple cardiopulmonary substructures (atria, lung, pericardium, and ventricles), including the minimum dose to the hottest x% volume (Dx%[Gy]), mean dose of the hottest x% (MOHx%[Gy]), and minimum, mean (Mean[Gy]), and maximum dose. The model building was based on Cox regression and given 191 candidate variables; a Bonferroni-corrected P value threshold of 0.0003 was used to identify predictors. To reduce overreliance on the most highly correlated variables, stepwise multivariable analysis (MVA) was repeated on 1000 bootstrapped replicates. Multivariate sets selected in ≥10% of replicates were fit to the training subset and then averaged to generate a final model. In the validation subset, discrimination was assessed using Harrell c-index, and calibration was tested using risk group stratification. Results: Four MVA models were identified on bootstrap. The averaged model included atria D45%[Gy], lung Mean[Gy], pericardium MOH55%[Gy], and ventricles MOH5%[Gy]. This model had excellent performance predicting OS in the validation subset (c = 0.89). Conclusions: The risk of death due to cardiopulmonary irradiation was accurately modeled, as demonstrated by predictions on the validation subset, and provides guidance on the delivery of safe thoracic radiotherapy.

AIMS To report the major characteristics and clinical outcomes of COVID-19 patients treated with ACE inhibitors and ARBs and compare the different effects of the two drugs for outcomes of COVID-19 patients. METHODS This is a retrospective, two-center case series of 198 consecutive COVID-19 patients with a history of hypertension. RESULTS Among 198 patients, 58 (29.3%) and 16 (8.1%) were on were on ARB and ACEI, respectively. Patients who were on ARB or ACEI/ARB had a significantly lower rate of severe illness and ARDS when compared with patients treated with ACEI alone or not receiving RAAS blocker (P＜0.05). The Kaplan-Meier survival curve showed that patients with ARB in their antihypertensive regimen had a trend towards a higher survival rate when compared with individuals without ARB (adjusted hazard ratio, 0.27; 95% CI, 0.07-1.02; P=0.054). The occurrence rates of severe illness, ARDS, and death were similar in the two groups regardless of receiving ACEI. The Cox-regression analysis to compared ACEI vs. ARB groups showed a significantly lower mortality rate in the ARB group (adjusted hazard ratio, 0.03; 95% CI, 0.00-0.58; P=0.02). CONCLUSIONS Our data may provide some evidence of using ARB, but not ACEI, was associated with a reduced rate of severe illness and ARDS, indicating their potential protective impact in COVID-19. Further large sample sizes and multiethnic populations are warranted to confirm our findings.

Abstract Introduction: Anti-thyroid Drugs (ATD) have become the most frequently used treatment for Graves’ disease (GD) in the United States. However, the response to this therapy is variable. Factors that predict biochemically responsive vs. biochemically persistent disease remain unknown. Identifying predictors of disease poorly responsive to ATD can help guide treatment decision making, follow up planning and prognosis. Methods: From a database of patients with GD treated with ATD and receiving care at an academic medical center between 2009–2019, we selected adults with incident GD treated with ≥14 days of ATD. Results: 172 patients (from a database of 730 patients with GD on ATD) were sampled for the purpose of this pilot and 97 of these met inclusion criteria. Patients had a median age of 50 (18–90); female, 70.1%; never smokers, 64.9%; median goiter size of 40 g (15–100); and median TRAb on presentation of 8.1 mIU/L (1.0- 60). Graves’ orbitopathy (GO) was present in 13.4% at baseline. Patients (100%) were started on methimazole at a median dose of 20 mg (2.5–60). The median time from presentation until biochemical improvement (defined as the first instance of FT4 ≤1.7 ng/dL) was 120.9 days (18–1525), and to biochemical euthyroidism (normal TSH & FT4) was 251 days (41–1259) including a median of 3 (0–17) dose adjustments. In a univariate analysis, response to ATD was divided into two groups; biochemically responsive and biochemically persistent disease (based on reaching biochemical improvement in ≤6 months, or &gt;6 months respectively). Biochemically persistent disease was more common in those with GO at presentation (38.5% vs.11.1%) (p .024). There was a trend towards greater prevalence of biochemically persistent disease in those with TRAb ≥ 8.0 mIU/L (46.2% vs. 27.8%) (p .204), and goiter estimated 30 grams or above by physical examination (30.8% vs. 19.4%) (p .460). Biochemically responsive disease was associated with higher frequency of hypothyroidism during treatment (p .047). Conclusion: Our preliminary results illustrate the spectrum of response to ATD and predictors of biochemically persistent disease. We aim to expand this analysis utilizing a large database. As use of ATD increases, clinicians and patients can apply this data to estimate response to therapy, and identify patients that may require more aggressive therapy, thereby tailoring management plans.

Abstract Background: It is estimated that 10-25% of patients with hypothyroidism use desiccated thyroid extract (DTE) as their primary thyroid hormone replacement medication, despite concerns about the risk of thyrotoxicosis associated with DTE use. It is unclear why many patients prefer the use of DTE as a thyroid hormone replacement formulation over guideline-concordant therapies such as levothyroxine (LT4). Methods: We conducted a mixed-methods study by analyzing patient-reported information from patient online forums to better understand patient preferences for and attitudes toward the use of DTE to treat hypothyroidism. We searched the 10 most popular patient forums based on number of users (WebMD, Topix, Health questions, Patients like me, Drugs.com, Endocrine Web, Everyday Health, Talk Health Partnership, Spark People and Patients.info) using the key terms: desiccated thyroid extract, desiccated thyroid treatment, thyroid USP, commercial names of DTE (Armour Thyroid® or Natural Thyroid®), thyroid extract, AND hypothyroidism. Unique posts were retrieved from those websites between each forum’s inception to March 2018. From these posts, we extracted descriptive information on patient demographics and clinical characteristics and qualitatively analyzed posts’ content to further explore patient perceptions on DTE and other thyroid hormone replacement therapies. Results: Unique 1,235 posts were initially retrieved from the included patient forums. After the initial screening, we selected data from three of these forums (WebMD, Patients Like Me, and Drugs.com) based on the completeness of the available information (673 posts). Nearly half (45%) of patients reported that a clinician initially drove their interest in trying DTE. Patients described many reasons for switching from a previous therapeutic approach to DTE, including lack of improvement in symptoms (58%) and the development of side effects (22%). Among a majority of patients, DTE was described as moderately-to-majorly effective overall (81%) and more effective than the previous therapy (77%). The most frequently described benefits associated with DTE use were an improvement in clinical symptoms (56%) as well as a change in overall well-being (34%). One-fifth of patients described side effects related to the use of DTE. Qualitative analysis of posts’ content supported these findings and raised additional issues around the need for individualizing therapy approaches for hypothyroidism as well as difficulties obtaining DTE. Conclusions: Among patients with hypothyroidism, a subset may prefer DTE over guideline-concordant therapies for many reasons, including perceived effectiveness, despite the risks associated with DTE. Future work should incorporate patient-reported outcomes to better elucidate the mechanisms responsible for therapy preferences in this subset of patients.
