ImportanceLip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning.ObjectiveTo analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates.Evidence ReviewThe incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019.FindingsIn 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia.Conclusions and RelevanceIn this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts.

AbstractBackgroundEvidence on the impact of obesity on catheter ablation for ventricular tachycardia (VT) is scarce.Method and ResultsWe queried the Nationwide Readmissions Database to determine the hospital outcomes and procedural complications of VT ablation among the obese and nonobese populations. Obesity was associated with a more prolonged length of stay (p < .01), higher cost of hospitalization (p < .01), and higher rates of pericardial effusion or hemopericardium (p = .05) and vascular complications (p = .05). There was no significant difference in early mortality, 30‐day readmissions, and other procedural complications.ConclusionVT ablation could be performed relatively safely among patients with obesity.

e22514 Background: Several colorectal cancer (CRC) screening tests, shown to reduce CRC incidence and mortality, are recommended for average-risk adults aged 45-75 years. CRC screening is underutilized in the US with access to facility-based options, such as colonoscopy, representing a barrier to screening. Stool-based tests are guideline-endorsed and offer patients a convenient and more accessible CRC screening option that can be completed at home. Provider recommendation is consistently identified as the primary factor driving patient adherence. Understanding how aspects of patient-provider communication influence CRC screening can inform interventions to improve adherence. We developed a survey, informed by behavioral theory, to identify communication factors associated with completion of mt-sDNA screening. Methods: Adults aged 45-75 years, with a US postal address, who received a valid order for mt-sDNA and whose kit was shipped between 5/21-9/21 were eligible for sampling. The survey was administered by RTI International between 3/22-6/22. Participants could complete electronic or paper surveys. We fit a multivariable logistic regression to identify patient-provider communication factors associated with mt-sDNA test completion. Results: 2,973 respondents completed the survey (response rate = 21.7%). The majority (77.3%) completed the mt-sDNA test and said they would be ‘very likely’ (76.8%) to complete Cologuard in the future. The proportion of respondents who had conversations with their healthcare provider about Cologuard, and the specific content of those conversations, was significantly different between completers and non-completers and between respondents who said they were ‘very likely’ to complete Cologuard in the future compared to respondents who were not. Results from a binary logistic regression suggested that discussions with a healthcare provider related to step-by-step instructions for completing Cologuard (OR = 1.62) and needing to have a colonoscopy follow-up (OR = 1.93), as well as feeling included ‘a great deal’ in the decision-process with respondents’ healthcare provider (compared to ‘somewhat’ or ‘not at all’) increase the odds of kit completion. Additionally, healthcare provider discussions relating to test cost (OR = 1.47) and performance (OR = 1.72), as well as feeling included ‘a great deal’ in the decision-process was positively associated with respondents indicating they were ‘very likely’ to use Cologuard in the future. Provider discussions about the cost of a follow-up colonoscopy was negatively associated with a ‘very likely’ future user (OR = 0.52). Conclusions: Healthcare providers play a key role in patient adherence to CRC screening and must be appropriately prepared and resourced to educate and to engage patients in shared decision-making about CRC screening.

ImportanceIncreased cancer risk in first-degree relatives of probands with pancreatic ductal adenocarcinoma (PDAC probands) who carry pathogenic or likely pathogenic germline variants (PGVs) in cancer syndrome–associated genes encourages cascade genetic testing. To date, unbiased risk estimates for the development of cancers on a gene-specific basis have not been assessed.ObjectiveTo quantify the risk of development of PDAC and extra-PDAC among first-degree relatives of PDAC probands who carry a PGV in 1 of 9 cancer syndrome–associated genes—ATM, BRCA1, BRCA2, PALB2, MLH1, MSH2, MSH6, PMS2, and CDKN2A.Design, Setting, and ParticipantsThis case series focused on first-degree relatives of PDAC probands carrying PGVs in specific cancer syndrome–associated genes. The cohort comprised clinic-ascertained patients enrolled in the Mayo Clinic Biospecimen Resource for Pancreas Research registry with germline genetic testing. In total, 234 PDAC probands carrying PGVs were drawn from the prospective research registry of 4562 participants who had undergone genetic testing of cancer syndrome–associated genes. Demographic and cancer-related family histories were obtained by questionnaire. The data were collected from October 1, 2000, to December 31, 2021.Main Outcomes and MeasuresFor the PDAC probands, the genetic test results of the presence of PGVs in 9 cancer syndrome–associated genes were obtained by clinical testing. Cancers (ovary, breast, uterus or endometrial, colon, malignant melanoma, and pancreas) among first-degree relatives were reported by the probands. Standardized incidence ratios (SIRs) were used to estimate cancer risks among first-degree relatives of PDAC probands carrying a PGV.ResultsIn total, 1670 first-degree relatives (mean [SD] age, 58.1 [17.8] years; 853 male [51.1%]) of 234 PDAC probands (mean [SD] age, 62.5 [10.1] years; 124 male [53.0%]; 219 [94.4%] White; 225 [98.7%] non-Hispanic or non-Latino]) were included in the study. There was a significantly increased risk of ovarian cancer in female first-degree relatives of probands who had variants in BRCA1 (SIR, 9.49; 95% CI, 3.06-22.14) and BRCA2 (SIR, 3.72; 95% CI, 1.36-8.11). Breast cancer risks were higher with BRCA2 variants (SIR, 2.62; 95% CI, 1.89-3.54). The risks of uterine or endometrial cancer (SIR, 6.53; 95% CI, 2.81-12.86) and colon cancer (SIR, 5.83; 95% CI, 3.70-8.75) were increased in first-degree relatives of probands who carried Lynch syndrome mismatch repair variants. Risk of PDAC was also increased for variants in ATM (SIR, 4.53; 95% CI, 2.69-7.16), BRCA2 (SIR, 3.45; 95% CI, 1.72-6.17), CDKN2A (SIR, 7.38; 95% CI, 3.18-14.54), and PALB2 (SIR, 5.39; 95% CI, 1.45-13.79). Melanoma risk was elevated for first-degree relatives of probands with CDKN2A variants (SIR, 7.47; 95% CI, 3.97-12.77).Conclusions and RelevanceIn this case series, the presence of PGVs in 9 cancer syndrome–associated genes in PDAC probands was found to be associated with increased risk of 6 types of cancers in first-degree relatives. These gene-specific PDAC and extra-PDAC cancer risks may provide justification for clinicians to counsel first-degree relatives about the relevance and importance of genetic cascade testing, with the goal of higher uptake of testing.

Background: Tuina has gained widespread attention and utilization for the management of chronic nonspecific low back pain (CNLBP). However, evidence-based guidance for choosing accurate and appropriate outcome measures of Tuina is lacking. The objective of this study is to systematically synthesize the existing outcome measures reported in randomized controlled trials (RCTs) evaluating Tuina therapy in CNLBP. Methods: Electronic literature searches were conducted in multiple English and Chinese databases from their inception to May 2022. RCTs were included if they involved clinical outcome measures in Tuina treatment for patients with CNLBP. Outcome instruments for each study were extracted and analyzed. Evidence from included studies were assessed using the Cochrane risk-of-bias tool. Results: Of the 735 identified articles, 17 articles with 1628 participants were included. Measurement domains in these RCTs were mainly reported in terms of pain (94%) and physical activity (71%), followed by safety (41%), Chinese medicine outcome (35%), and quality of life (12%). Moreover, several limitations with existing outcomes were reported, including lack of emphasis on the evaluation of quality of life, inadequate safety monitoring, as well as insufficient and vague Chinese medicine outcome measures. All trials were deemed to be of poor methodological quality. Conclusion: Pain and physical disability were the most frequently studied outcome domains in CNLBP treated by Tuina therapy. More rigorous and high-quality trials with appropriately selected outcome measures are needed in the future.

Abstract Background: Multiple guideline-recommended colorectal cancer (CRC) screening options have been shown to reduce CRC incidence and mortality among average-risk patients. Yet, CRC screening continues to be underutilized in the US. Provider recommendation has consistently shown to improve screening completion. Our study aimed to delineate the pathways through which provider communication influences CRC screening completion. We tested how provider communication about the "Why” and “How” of mt-sDNA screening contributes to mt-sDNA screening intention through influencing patients’ screening outcome expectancies and perceived behavioral control. Methods: Data came from a behavioral theory-informed survey that we developed to identify psychosocial factors associated with mt-sDNA screening. The survey was administered between 3/22-6/22 by RTI International, with a sample of US adults ages 45-75 who received a valid order for mt-sDNA screening with a shipping date between 5/21-9/21. Participants completed an electronic or paper survey. We measured patients’ reports of providers’ “Why” communication with items on mt-sDNA screening performance, advantages/disadvantages, and cost. Providers’ “How” communication was measured with items on instructions and need for follow-up testing. We tested the proposed relationships using structural equation modeling and tested indirect effects using bootstrapping. Results: A total of 2973 participants completed the survey (response rate: 21.7%). “Why” communication was positively associated with perceived effectiveness of mt-sDNA screening (b = 0.349, p &lt; .001) and negatively associated with CRC worry (b = -0.078, p = .002). “How” communication was positively associated with perceived ease of use (b = 0.392, p &lt; .001) and perceived comfort of mt-sDNA screening (b = 0.138, p &lt; .001). Perceived effectiveness and perceived ease of use were positively associated with intention to complete mt-sDNA screening (b = 0.404, p &lt; .001; b = 0.339, p &lt; .001). “Why” communication contributed to screening intention through influencing perceived effectiveness (b-indirect effect = 0.141, 95% CI: 0.115, 0.177). “How” communication contributed to screening intention through influencing perceived ease of use (b-indirect effect = 0.133, 95% CI: 0.104, 0.172). Conclusions: Improving patients’ beliefs about the effectiveness and ease of use of screening may be one pathway through which provider communication contributes to CRC screening completion. Efforts are needed to develop and implement provider-patient communication strategies and toolkits that are efficacious at fostering patient understanding of the rationale for CRC screening and the effectiveness of available screening options as well as addressing barriers and enhancing patients’ self-efficacy in completing their preferred screening option.

Objective: Chronic nonspecific low back pain (CNLBP) is a serious medical and social problem resulting in functional decline and decreased work ability. Tuina, a form of manual therapy, has been sparsely used to treat patients with CNLBP. To systematically assess the efficacy and safety of Tuina for patients with CNLBP. Methods: Multiple English and Chinese literature databases were searched until September 2022 for randomized controlled trials (RCTs) of Tuina in the treatment of CNLBP. The methodological quality was assessed using the Cochrane Collaboration’s tool, and certainty of the evidence was determined with the online Grading of Recommendations, Assessment, Development and Evaluation tool. Results: Fifteen RCTs with 1390 patients were included. Tuina demonstrated a significant effect on pain (SMD: −0.82; 95% CI −1.12 to −0.53; P < .001; I 2 = 81%) and physical function (SMD: −0.91; 95% CI −1.55 to −0.27; P = .005; I 2 = 90%) when compared to control. However, Tuina resulted in no significant improvement for quality of life (QoL) (SMD: 0.58; 95% CI −0.04 to 1.21; P = .07; I 2 = 73%;) compared to control. The Grading of Recommendations, Assessment, Development and Evaluation evidence quality was determined to be low level for pain relief, physical function, and QoL measurements. Only six studies reported adverse events; none were serious. Conclusion: Tuina might be an effective and safe strategy for treating CNLBP in terms of pain and physical function, but not for QoL. The study results should be interpreted with caution for their low-level evidence. More multicenter, large-scale RCTs with a rigorous design are required to further confirm our findings.

Abstract Background STRIDE-II guidelines recommend endoscopic healing as an important treatment goal in Crohn’s disease (CD). This study evaluated the association of achieving endoscopic outcomes at week 12 and clinical outcomes at week 52 of maintenance treatment in patients with CD treated with upadacitinib (UPA). Methods This post-hoc analysis evaluated data from two Phase 3 UPA induction (U-EXCEED and U-EXCEL) trials and the maintenance (U-ENDURE) trial in patients with moderate to severe CD. Patients who responded to 12-week induction therapy with UPA (45 mg per day [QD]) in U-EXCEED or U-EXCEL and received maintenance therapy with UPA (15 or 30 mg QD) up to 52 weeks in U-ENDURE were included. Clinical outcomes (CD activity index [CDAI] remission, CDAI response, steroid-free CDAI remission, high sensitivity C-reactive protein [hs-CRP] level ≤5 mg/L, and fecal calprotectin level [F-cal] ≤250 mcg/g), were evaluated at week 52 and compared between patients who achieved endoscopic response, endoscopic remission and ulcer-free endoscopy (absence of ulceration) at week 12 and those who did not using Chi-square test. Results Of 337 clinical responders included in the analyses, 152 (45.1%), 87 (25.8%), and 75 (22.3%) patients achieved endoscopic response, endoscopic remission, and ulcer-free endoscopy, respectively, at the end of induction. Significantly more patients who achieved an endoscopic response at end of induction (vs those who did not) attained clinical outcomes at week 52 (CDAI remission, 52.0% vs 34.6%; CDAI response, 54.6% vs 39.5%; hsCRP ≤5 mg/L, 52.0% vs 30.8%; and F-cal ≤250 mcg/g, 42.1% vs 21.6%; P≤0.01, Table 1). Patients who achieved an endoscopic response vs those who did not at end of induction were also more likely to attain steroid-free CDAI remission (50.0% vs 30.9%) at week 52, (P≤0.05, Table 1). Similar findings were observed in patients who achieved endoscopic remission vs those who did not at end of induction (P≤0.01, Table 1). Significantly more patients attained CDAI remission (58.7% vs 37.7%), CDAI response (58.7% vs 42.7%), hsCRP ≤5 mg/L (58.7% vs 35.0%) and F-cal ≤250 mcg/g (50.7% vs 25.0%) at week 52, among patients who achieved ulcer-free endoscopy vs those who did not at end of induction (P≤0.05, Table 1). Conclusion Achieving endoscopic outcomes at end of induction is associated with meaningful improvement in symptoms and inflammatory biomarkers at 52 weeks for patients with CD receiving UPA therapy. Endoscopic remission and ulcer-free endoscopy are associated with very similar long-term benefits.
