ObjectiveTo compare the postprocedural health care utilization and cost of septal myectomy (SM) and alcohol septal ablation (ASA).Patients and MethodsUsing the OptumLabs Data Warehouse, we analyzed de-identified claims data of adult patients undergoing SM and ASA for obstructive hypertrophic cardiomyopathy from January 1, 2006, through December 31, 2018. We used propensity score weighting to compare the 2-year incidence rates of emergency department visits and rehospitalizations after SM and ASA.ResultsWe identified 953 patients in total: 660 underwent SM and 293 underwent ASA. There was no difference in the risk (odds ratio, 1.1; 95% CI, 0.6 to 1.8) or frequency (incidence rate ratio, 1.1; 95% CI, 0.8 to 1.5) of emergency department visits, but the annual risk of hospital readmission was 10.8% after SM and 25.9% after ASA during the second postoperative year (P=.004). In those who were ever readmitted, the average length of hospital stay within the first 2 years after ASA was 1.6 times as long as that after SM (incidence rate ratio, 1.6; 95% CI, 1.0 to 2.4). Overall, the 2-year cumulative postprocedural cost was significantly higher after ASA (P<.001).ConclusionCompared with ASA, SM is associated with fewer hospital readmissions and lower 2-year postprocedural health care cost. 相似文献

ObjectiveTo evaluate how breast cancers come to clinical attention (mode of detection [MOD]) in a population-based cohort, determine the relative frequency of different MODs, and characterize patient and tumor characteristics associated with MOD.Patients and MethodsWe used the Rochester Epidemiology Project to identify women ages 40 to 75 years with a first-time diagnosis of breast cancer from May 9, 2017, to May 9, 2019 (n=500) in a 9-county region in Minnesota. We conducted a retrospective medical record review to ascertain the relative frequency of MODs, evaluating differences between screening mammography vs all other MODs by breast density and cancer characteristics. Multiple logistic regression was conducted to examine the likelihood of MOD for breast density and stage of disease.ResultsIn our population-based cohort, 162 of 500 breast cancers (32.4%) were detected by MODs other than screening mammography, including 124 (24.8%) self-detected cancers. Compared with women with mammography-detected cancers, those with MODs other than screening mammography were more frequently younger than 50 years of age (P=.004) and had higher-grade tumors (P=.007), higher number of positive lymph nodes (P<.001), and larger tumor size (P<.001). Relative to women with mammography-detected cancers, those with MODs other than screening mammography were more likely to have dense breasts (odds ratio, 1.87; 95% CI, 1.20 to 2.92; P=.006) and advanced cancer at diagnosis (odds ratio, 3.58; 95% CI, 2.29 to 5.58; P<.001).ConclusionOne-third of all breast cancers in this population were detected by MODs other than screening mammography. Increased likelihood of nonmammographic MODs was observed among women with dense breasts and advanced cancer. 相似文献

Breast cancer remains the most common cancer in women in the United States. For certain women at high risk for breast cancer, endocrine therapy (ET) can greatly decrease the risk. Tools such as the Breast Cancer Risk Assessment Tool (or Gail Model) and the International Breast Cancer Intervention Study risk calculator are available to help identify women at increased risk for breast cancer. Physician awareness of family history, reproductive and lifestyle factors, dense breast tissue, and history of benign proliferative breast disease are important when identifying high-risk women. The updated US Preventive Services Task Force and American Society of Clinical Oncology guidelines encourage primary care providers to identify at-risk women and offer risk-reducing medications. Among the various ETs, which include tamoxifen, raloxifene, anastrozole, and exemestane, tamoxifen is the only one available for premenopausal women aged 35 years and older. A shared decision-making process should be used to increase the usage of ET and must be individualized. This individualized approach must account for each woman’s medical history and weigh the benefits and risks of ET in combination with the personal values of the patient. 相似文献

ObjectivesTo investigate the prevalence and risk factors for adhesive capsulitis in postoperative breast cancer patients up to 5 years after surgery who were attending an outpatient community cancer rehabilitation program, and to determine whether any significant relationship exists between arm lymphedema and adhesive capsulitis.DesignCross-sectional observational study.SettingNational cancer rehabilitation center.ParticipantsAsian women (N=135) who underwent breast surgery and were referred for an outpatient community cancer rehabilitation program.InterventionsNot applicable.Main Outcome MeasuresPresence of adhesive capsulitis, lymphedema.ResultsThe prevalence of adhesive capsulitis and lymphedema in this population was 22.2% and 33.3%, respectively. A history of mastectomy (odds ratio [OR], 3.93; 95% confidence interval [CI], 1.23-12.63; P=.021), mastectomy with reconstruction (OR, 2.72; 95% CI, 1.27-30.54; P=.024), and lymphedema (OR, 7.92; 95% CI, 2.73-22.95; P<.001) were found to be significantly associated with adhesive capsulitis on multivariate analysis.ConclusionsAdhesive capsulitis and lymphedema are common in breast cancer survivors. The design of cancer rehabilitation programs for breast cancer survivors should include surveillance and management of adhesive capsulitis, especially in the presence of lymphedema. 相似文献

ObjectiveTo investigate the association between type 1 diabetes mellitus (T1D) and type 2 diabetes mellitus (T2D) with risk of sudden cardiac arrest (SCA).MethodsIn a prospective community-based study of SCA from February 1, 2002, through November 30, 2019, we ascertained 2771 cases age 18 years of age or older and matched them to 8313 controls based on geography, age, sex, and race/ethnicity. We used logistic regression to evaluate the independent association between diabetes, T1D, T2D, and SCA.ResultsPatients had a mean age of 64.5±15.9 years, were 33.3% female and 23.9% non-White race. Overall, 36.7% (n=1016) of cases and 23.8% (n=1981) of controls had diabetes. Among individuals with diabetes, the proportion of T1D was 6.5% (n=66) among cases and 2.0% among controls (n=40). Diabetes was associated with 1.5-times higher odds of SCA. Compared with those without diabetes, the odds ratio and 95% CI for SCA was 4.36 (95% CI, 2.81 to 6.75; P<.001) in T1D and 1.45 (95% CI, 1.30 to 1.63; P<.001) in T2D after multivariable adjustment. Among those with diabetes, the odds of having SCA were 2.41 times higher in T1D than in T2D (95% CI, 1.53 to 3.80; P<.001). Cases of SCA with T1D were more likely to have an unwitnessed arrest, less likely to receive resuscitation, and less likely to survive compared with those with T2D.ConclusionType 1 diabetes was more strongly associated with SCA compared with T2D and had less favorable outcomes following resuscitation. Diabetes type could influence the approach to risk stratification and prevention of SCA. 相似文献

Worldwide there has been an alarming increase in the incidence of early-onset colorectal cancer (eoCRC). This prompted the United States Preventive Services Task Force to lower the age of colorectal cancer screening to 45 years for average-risk individuals. Nurse practitioners have an important role in implementing these evidence-based guidelines, understanding the risk factors for eoCRC, identifying concerning signs and symptoms of eoCRC, and providing thorough evaluations. Although more research is needed to understand eoCRC, nurse practitioners can use current knowledge to make meaningful impacts on the communities they serve. 相似文献

Solid organ transplant recipients (SOTRs) are at increased risk for the development of skin cancer compared with the general population, which requires consistent monitoring and management from a multidisciplinary team. The aim of this review is to provide a comprehensive overview for nondermatologist clinicians, outlining skin cancer diagnosis, treatment pearls, and skin cancer prevention strategies as they relate to SOTRs. A comprehensive search of the literature was conducted through the MEDLINE database with search terms including organ transplantation, transplant recipient, skin cancer, cutaneous neoplasms, management, and therapies. The search was limited to the English language and dates ranging from January 1, 2011, to December 28, 2021. All studies were reviewed for inclusion. Skin cancer will develop in more than half of SOTRs at some point in their life, most often nonmelanoma skin cancer such as basal cell carcinoma or squamous cell carcinoma. Melanoma and rarer cutaneous malignant neoplasms, such as Merkel cell carcinoma and Kaposi sarcoma, are also more frequent among SOTRs. A multidisciplinary effort at skin cancer screening and patient education is invaluable to prevent skin cancer–related morbidity and mortality in this population of patients. Reduction in immunosuppressive medications and surgical intervention are effective therapeutic approaches, and more novel systemic therapies including G protein–coupled receptor inhibitors and immune checkpoint inhibitors are possible options when traditional treatment approaches are not feasible. Checkpoint inhibitor therapy, however, comes with the risk of allograft rejection. With a growing and aging SOTR population, it is essential that SOTRs have support from dermatologists and nondermatologists alike in skin cancer prevention and treatment. 相似文献

Relative survival and disease-specific survival are two statistics that measure net survival from a cancer diagnosis, excluding other causes of death. In most cases, these two rates are comparable. However, in some cancer types for which cancer screening is performed, relative survival is often greater than disease-specific survival. This divergence has been attributed to mechanisms such as the “healthy user effect” and overdiagnosis of indolent tumors detected by screening. Using relative survival rate as a marker of these mechanisms, we examined the association of breast cancer screening with relative survival rates for women diagnosed with early-stage breast cancer. In population-based data from the National Cancer Institute’s Surveillance, Epidemiology and End Results registry, we examined relative survival rates in women diagnosed with stage I breast cancer or ductal carcinoma in situ who were in highly screened vs less-highly screened groups, based on time period, age group, and insurance status. In this analysis, relative survival rates for early-stage breast cancer were higher than disease-specific survival, even exceeding 100% in populations experiencing higher rates of screening (ie, women diagnosed during the era of widespread uptake of mammography, age older than 40 years, and women with health insurance coverage). The favorable outcomes observed in screen-detected breast cancers are at least in part attributable to the healthy user effect and overdiagnosis of indolent tumors. Therefore, survival rates may not accurately reflect the effectiveness of cancer screening. These findings have implications for counseling of patients and future clinical studies of active monitoring approaches in breast cancer. 相似文献

ObjectiveTo describe the temporal association and identify risk factors between cancer diagnosis and various types of arterial thromboembolism (ATE).Patients and MethodsWe inquired an aggregated electronic health record database (Explorys, IBM Corp., Armonk, New York) and identified patients with cancer from January 1999 to October 2019, with various types of ATE, including myocardial infarction, acute ischemic stroke, acute limb ischemia, acute mesenteric ischemia, acute renal infarction, and retinal artery occlusion. We investigated the temporal relationship between cancer diagnosis and ATE events by examining the incidence ratio (IR) of ATE before and after diagnosis of cancer.ResultsWe identified 305,384 patients with cancer and ATE. The 30-day interval IR of total ATE was elevated shortly before and after cancer diagnosis, which was consistent among different ATE and cancer types. The incidence was highest within a 330-day window (90 days before and 240 days after cancer diagnosis), and IR peaked at 13.9 (95% confidence interval [CI], 13.6 to 14.2) in the first 30 days following diagnosis of cancer. Compared with patients with cancer who never developed ATE, patients with ATE had more cardiovascular risk factors at baseline. Patients with brain cancer, lung cancer, colorectal cancer, and pancreatic cancer had the highest risk of developing ATE, whereas ATE type was anatomically associated with cancer type.ConclusionIn this observational study of an aggregated US patient population, those with newly diagnosed cancer had increased risk of ATE events. This risk was most elevated in a 330-day window around cancer diagnosis and was consistent across different types of ATE and cancer. 相似文献

ObjectiveTo compare the bleeding risk in patients with gastrointestinal (GI) cancer with that in patients with non-GI cancer treated with anticoagulation for acute cancer-associated venous thromboembolism (Ca-VTE).Patients and MethodsConsecutive patients with Ca-VTE seen at the Mayo Thrombophilia Clinic between March 1, 2013, and April 20, 2020, were observed prospectively to assess major bleeding and clinically relevant nonmajor bleeding (CRNMB).ResultsIn the group of 1392 patients with Ca-VTE, 499 (35.8%) had GI cancer including 272 with luminal GI cancer (lower GI, 208; upper GI, 64), 176 with pancreatic cancer, and 51 with hepatobiliary cancer. The rate of major bleeding and CRNMB in patients with GI cancer was similar to that in 893 (64.2%) patients with non-GI cancer treated with apixaban, rivaroxaban, or enoxaparin. Apixaban had a higher rate of major bleeding in luminal GI cancer compared with the non-GI cancer group (15.59 vs 3.26 per 100 person-years; P=.004) and compared with enoxaparin in patients with luminal GI cancer (15.59 vs 3.17; P=.04). Apixaban had a lower rate of CRNMB compared with rivaroxaban in patients with GI cancer (3.83 vs 9.40 per 100 person-years; P=.03). Patients treated with rivaroxaban in the luminal GI cancer group had a major bleeding rate similar to that of patients with non-GI cancer (2.04 vs 4.91 per 100 person-years; P=.37).ConclusionApixaban has a higher rate of major bleeding in patients with luminal GI cancer compared with patients with non-GI cancer and compared with enoxaparin in patients with luminal GI cancer. Rivaroxaban shows no increased risk of major bleeding in patients with GI cancer or luminal GI cancer compared with patients with non-GI cancer.Trial RegistrationClinicalTrials.gov identifier: NCT03504007. 相似文献

ObjectiveTo assess whether long-term cancer survivors (≥5 years after diagnosis) are at an increased risk of experiencing an opioid-related emergency department (ED) visit or hospitalization compared with persons without cancer.MethodsA 1:1 matched retrospective cohort study was performed using the Surveillance, Epidemiology, and End Results–Medicare linked data sets. The analysis was conducted from October 2020 to December 2020 in persons who lived 5 years or more after a breast, colorectal, lung, or prostate cancer diagnosis matched to noncancer controls on the basis of age, sex, race, pain conditions, and previous opioid use. Fine-Gray regression models were used to assess the relationship between cancer survivorship status and opioid-related ED visit or hospitalization.ResultsThe incidence of opioid-related ED visits and hospitalizations was 51.2 (95% CI, 43.5 to 59.8) and 62.2 (95% CI, 53.4 to 72.1) per 100,000 person-years among cancer survivors and matched noncancer controls, respectively. No significant association was observed between survivorship and opioid-related adverse event among opioid naive (hazard ratio, 0.79; 95% CI, 0.61 to 1.02) and non-naive (hazard ratio, 1.26; 95% CI, 0.84 to 1.89) cohorts.ConclusionCancer survivors and noncancer controls had a similar risk of an ED visit or inpatient admission. Guidelines and policies should promote nonopioid pain management approaches especially to opioid non-naive older adults, a population at high risk for an opioid-related ED visit or hospitalization. 相似文献

ObjectivesTo test the effect of adding neural mobilization (NM) versus myofascial release (MFR) to stabilization exercises (SE) on disability, pain, and lumbar range of motion (ROM) in patients with lumbar spine fusion (LSF).DesignA single blinded, parallel groups, randomized controlled trial.SettingOutpatient public and governmental hospital clinics.ParticipantsPatients (N=60) who had undergone LSF were randomly assigned into 3 equal groups.InterventionGroup I received NM plus SE, group II received MFR and SE, and group III received SE only. Each group visited the hospital 3 times a week for 4 weeks.Main Outcome MeasuresOswestry disability index (ODI), visual analog scale, and back range of motion (BROM) were assessed before starting treatment, immediately after finishing treatment, and 1 month later.ResultsThere were statistically significant differences among the groups regarding the ODI and pain (P<.05) in favor of the study groups, but no statistically significant differences were found among groups regarding the BROM outcome (P>.05). Regarding the within-group effect, statistically significant differences were found in all outcomes after 1 month of treatment, as well as after 1 month of follow-up in each group (P<.05).ConclusionsPatients who received NM or MFR combined with SE demonstrated better improvement, in favor of the NM group, regarding disability and pain than patients who received SE alone after LSF. No differences were found among the groups regarding lumbar ROM. 相似文献

BackgroundWith the rapid development of information technology, hospital information systems (HISs) have been deeply applied in the medical field and have shown broad application prospects. There are still some noninteroperable clinical information systems that pose an obstacle to the effective coordination of care, such as cancer pain management.AimTo construct a chain management information system for cancer pain and explore its clinical application effect.MethodsA quasiexperimental study was conducted in the inpatient department of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. A total of 259 patients were nonrandomly divided into two groups: the experimental group (after the system was applied, n = 123) and the control group (before the system was applied, n = 136). The cancer pain management evaluation form score, patient satisfaction with pain control, pain score at admission and discharge, and the worst pain score during hospitalization were compared between the two groups.ResultsCompared with the control group, the score of the cancer pain management evaluation form was significantly higher (p < .05). There were no statistically significant differences in worst pain intensity, pain score at admission and discharge, and patients’ satisfaction with pain control between the two groups.ConclusionsThe cancer pain chain management information system can enable nurses to evaluate and record pain in a more standardized way, but it has no significant effect on the pain intensity of cancer patients. 相似文献

ObjectiveTo evaluate the real-life use of a modified Gillmore algorithm with a "one-stop-shop” approach, bone scintigraphy (BS), a monoclonal gammopathy test (GT), a salivary gland biopsy (SGB), and genetic testing performed at the same time for the diagnosis of cardiac amyloidosis at the French National Reference Centre for Cardiac Amyloidosis (Henri Mondor Hospital, Créteil, France).MethodsThis retrospective cohort study included a total of 1222 patients with suspected amyloidosis who underwent BS and GT between June 2008 and May 2019.ResultsOf 1222 patients, 349 had no cardiac uptake on BS and negative GT (BS?/GT?), 276 were BS?/GT positive (GT+), 420 patients were BS+/GT?, and 177 were BS+/GT+. Our one-stop-shop check-up enabled us to diagnose 892 (72.9%) patients; 330 (27.0%) patients required additional examinations, such as mass spectrometry and/or a cardiac biopsy. This subset notably included 112 patients with amyloid light chain amyloidosis. More than 64% of the patients with transthyretin amyloidosis or another type of amyloidosis were diagnosed during the one-stop shop visit. Sensitivity and specificity of BS for transthyretin amyloidosis diagnosis was 99% and 96%, respectively. For amyloid light chain diagnosis, sensitivity and specificity were 100% and 76%, respectively, for GT and 54% and 100%, respectively, for SGB. Of 910 transthyretin genetic tests, 205 (17%) detected mutations.ConclusionThe results of our real-life cohort study confirmed the ability of a one-stop-shop approach with a modified Gillmore algorithm to diagnose cardiac amyloidosis and the interest of simultaneous testing for earlier diagnosis. The SGB has diagnostic value because it is easy, quick, and less invasive than a cardiac biopsy. 相似文献

ObjectiveAcoustic attenuation in the propagation path of focused ultrasound ablation surgery determines the energy loss toward the focal region and is critical to the consequent treatment outcomes. In situ non-invasive, reliable, and accurate measurement is challenging for multi-layered heterogeneous tissues within the focusing angle.MethodsA novel measurement approach is proposed and its performance is evaluated using ex vivo porcine tenderloin and bovine heart. A big boiling bubble (i.e., larger than a few millimeters in size) was produced at the focus as a strong reflector inside the tissue, and the echo amplitudes were used to determine the acoustic attenuation. Two models, acoustic ray and energy loss, were developed to derive the equivalent acoustic attenuation coefficient for a focused beam.ResultsThe measured acoustic attenuation coefficients of ex vivo porcine tenderloin and bovine heart at 0.97 MHz and a thickness of 3 cm are 0.159 ± 0.002 and 0.250 ± 0.005 Np/cm, respectively, which are all within the scope of measured values in the literature. In addition, the echo amplitude is sensitive to the conditions of the propagation path, and the inverse acoustic attenuation coefficient of the silicone gel pad placed in front of the tissue sample was 0.807 ± 0.002 Np/cm, which is comparable to the measurement using the insertion substitution method, 0.766 ± 0.003 Np/cm.ConclusionOur proposed approach could determine the tissue acoustic attenuation for focused ultrasound ablation surgery reliably and accurately in situ. The easy operating protocol may allow clinical translation and adoption for improved safety and efficacy. 相似文献

ObjectiveTo investigate whether dual-energy x-ray absorptiometry (DXA) estimates of adiposity improve risk prediction for cardiometabolic diseases over traditional surrogates, body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) in older women.Patients and MethodsWe analyzed up to 9744 postmenopausal women aged 50 to 79 years participating in the Women’s Health Initiative who underwent a DXA scan and were free of cardiovascular disease and diabetes at baseline (October 1993 to December 1998) and followed through September 2015. Baseline BMI, WC, WHR, and DXA-derived percent total-body and trunk fat (%TrF) were incorporated into multivariable Cox proportional hazards models to estimate the risk of incident diabetes, atherosclerosis-related cardiovascular diseases (ASCVDs), heart failure, and death. Concordance probability estimates assessed the relative discriminatory value between pairs of adiposity measures.ResultsA total of 1327 diabetes cases, 1266 atherosclerotic cardiovascular disease (ASCVD) cases, 292 heart failure cases, and 1811 deaths from any cause accrued during a median follow-up of up to 17.2 years. The largest hazard ratio observed per 1 standard deviation increase of an adiposity measure was for %TrF and diabetes (1.77; 95% CI, 1.66-1.88) followed by %TrF and broadly defined ASCVD (1.22; 95% CI, 1.15-1.30). These hazard ratios remained significant for both diabetes (1.47; 95% CI, 1.37-1.57) and ASCVD (1.22; 95% CI, 1.14-1.31) even after adjusting for the best traditional surrogate measure of adiposity, WC. Percentage of trunk fat was also the only adiposity measure to demonstrate statistically significant improved concordance probability estimates over BMI, WC, and WHR for diabetes and ASCVD (all P<0.05).ConclusionDXA-derived estimates of abdominal adiposity in postmenopausal women may allow for substantially improved risk prediction of diabetes over standard clinical risk models. Larger DXA studies with complete lipid biomarker profiles and clinical trials are needed before firm conclusions can be made. 相似文献
