RESUMEN

INTRODUCTION: Medicare significantly influences reimbursement rates, setting a standard that impacts private insurance policies. Despite declining rates in various specialties, the magnitude of these trends has not been examined in breast surgery. This study examines Medicare reimbursement trends for breast surgery operations. METHODS: Data for 10 breast operations from 2003 to 2023 were collected from the Medicare Physician Fee Look-Up Tool and yearly reimbursement was computed using the conversion factor. The year-to-year percentage change in reimbursement was calculated, and the overall median change was compared with the consumer price index (CPI) for inflation evaluation. All data were adjusted to 2023 United States dollars. The compound annual growth rate (CAGR) was calculated using inflation-adjusted data. RESULTS: Over the study period, reimbursement for the 10 breast operations had a mean unadjusted percentage increase of + 25.17%, while the CPI increased by 69.15% (p < 0.001). However, after adjustment, overall reimbursement decreased by - 20.70%. Only two operations (lumpectomy and simple mastectomy) saw increased inflation-adjusted Medicare reimbursement (+ 0.37% and + 3.58%, respectively). The CAGR was - 1.54% overall but remained positive for the same two operations (+ 0.02% and + 0.18%, respectively). Based on these findings, breast surgeons were estimated to be reimbursed $107,605,444 less in 2023 than if rates had kept pace with inflation over the past decade. CONCLUSION: Inflation-adjusted Medicare reimbursement rates for breast surgeries have declined from 2003 to 2023. This downward trend may strain resources, potentially leading to compromises in care quality. Surgeons, administrators, and policymakers must take proactive measures to address these issues and ensure the ongoing accessibility and quality of breast surgery.

RESUMEN

INTRODUCTION: Parathyroidectomy is recommended for severe secondary hyperparathyroidism (SHPT) due to end-stage kidney disease (ESKD), but surgery is underutilized. High quality and accessible online health information, recommended to be at a 6th-grade reading level, is vital to improve patient health literacy. This study evaluated available online resources for SHPT from ESKD based on information quality and readability. METHODS: Three search engines were queried using the terms "parathyroidectomy for secondary hyperparathyroidism," "parathyroidectomy kidney/renal failure," "parathyroidectomy dialysis patients," "should I have surgery for hyperparathyroidism due to kidney failure?," and "do I need surgery for hyperparathyroidism due to kidney failure if I do not have symptoms?" Websites were categorized by source and origin. Two independent reviewers determined information quality using JAMA (0-4) and DISCERN (1-5) frameworks, and scores were averaged. Cohen's kappa evaluated inter-rater reliability. Readability was determined using the Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, and Simple Measure of Gobbledygook tools. Median readability scores were calculated, and corresponding grade level determined. Websites with reading difficulties >6th grade level were calculated. RESULTS: Thirty one (86.1%) websites originated from the U.S., with most from hospital-associated (63.9%) and foundation/advocacy sources (30.6%). The mean JAMA and DISCERN scores for all websites were 1.3 ± 1.4 and 2.6 ± 0.7, respectively. Readability scores ranged from grade level 5-college level, and most websites scored above the recommended 6th grade level. CONCLUSIONS: Patient-oriented websites tailoring SHPT from ESKD are at a reading level higher than recommended, and the quality of information is low. Efforts must be made to improve the accessibility and quality of information for all patients.

RESUMEN

INTRODUCTION: Patients use the internet to learn more about health conditions. Non-English-speaking patients may face additional challenges. The quality of online breast cancer information, the most common cancer in women, is uncertain. This study aims to examine the quality of online breast cancer information for English and non-English-speaking patients. METHODS: Three search engines were queried using the terms: "how to do a breast examination," "when do I need a mammogram," and "what are the treatment options for breast cancer" in English, Spanish, and Chinese. For each language, 60 unique websites were included and classified by type and information source. Two language-fluent reviewers evaluated website quality using the Journal of American Medical Association benchmark criteria (0-4) and the DISCERN tool (1-5), with higher scores representing higher quality. Scores were averaged for each language. Health On the Net code presence was noted. Inter-rater reliability between reviewers was assessed. RESULTS: English and Spanish websites most commonly originated from US sources (92% and 80%, respectively) compared to Chinese websites (33%, P < 0.001). The most common website type was hospital-affiliated for English (43%) and foundation/advocacy for Spanish and Chinese (43% and 45%, respectively). English websites had the highest and Chinese websites the lowest mean the Journal of American Medical Association (2.2 ± 1.4 versus 1.0 ± 0.8, P = 0.002) and DISCERN scores (3.5 ± 0.9 versus 2.3 ± 0.6, P < 0.001). Health On the Net code was present on 16 (8.9%) websites. Inter-rater reliability ranged from moderate to substantial agreement. CONCLUSIONS: The quality of online information on breast cancer across all three languages is poor. Information quality was poorest for Chinese websites. Improvements to enhance the reliability of breast cancer information across languages are needed.

RESUMEN

INTRODUCTION: Presenting health information at a sixth-grade reading level is advised to accommodate the general public's abilities. Breast cancer (BC) is the second-most common malignancy in women, but the readability of online BC information in English and Spanish, the two most commonly spoken languages in the United States, is uncertain. METHODS: Three search engines were queried using: "how to do a breast examination," "when do I need a mammogram," and "what are the treatment options for breast cancer" in English and Spanish. Sixty websites in each language were studied and classified by source type and origin. Three readability frameworks in each language were applied: Flesch Kincaid Reading Ease, Flesch Kincaid Grade Level, and Simple Measure of Gobbledygook (SMOG) for English, and Fernández-Huerta, Spaulding, and Spanish adaptation of SMOG for Spanish. Median readability scores were calculated, and corresponding grade level determined. The percentage of websites requiring reading abilities >sixth grade level was calculated. RESULTS: English-language websites were predominantly hospital-affiliated (43.3%), while Spanish websites predominantly originated from foundation/advocacy sources (43.3%). Reading difficulty varied across languages: English websites ranged from 5th-12th grade (Flesch Kincaid Grade Level/Flesch Kincaid Reading Ease: 78.3%/98.3% above sixth grade), while Spanish websites spanned 4th-10th grade (Spaulding/Fernández-Huerta: 95%/100% above sixth grade). SMOG/Spanish adaptation of SMOG scores showed lower reading difficulty for Spanish, with few websites exceeding sixth grade (1.7% and 0% for English and Spanish, respectively). CONCLUSIONS: Online BC resources have reading difficulty levels that exceed the recommended sixth grade, although these results vary depending on readability framework. Efforts should be made to establish readability standards that can be translated into Spanish to enhance accessibility for this patient population.

RESUMEN

INTRODUCTION: Medicare determines reimbursement rates for medical services, often setting a benchmark that is followed by private insurers. Across various medical specialties, decreases in Medicare reimbursement have been observed. However, the extent of Medicare reimbursement for endocrine surgery remains unexplored. This study investigates the trajectory of reimbursement rates for endocrine surgical procedures. METHODS: Data spanning 2003 to 2023 were gathered from the Physician Fee Schedule Look-Up Tool for 16 endocrine operations and procedures. Each operation's or procedure's relative value units and conversion factor, which accounts for geographic variation in relative value units, are determined annually by the Centers for Medicare and Medicaid Services. The total annual Medicare reimbursement for each operation or procedure was determined by multiplying procedure-specific relative value units with the conversion factor. Raw yearly percentage changes in reimbursement were computed and compared to changes in the general consumer price index. All data were then corrected for inflation. The compound annual growth rate for each procedure was calculated using inflation-adjusted data. RESULTS: From 2003 to 2023, the mean unadjusted percentage change for all queried procedures was +14.14% (standard deviation 0.28). During this same time, the consumer price index increased by 69.15% (P < .001). After adjusting for inflation, the mean total adjusted percentage change for all queried procedures over the entire study period was -31% (standard deviation 0.17). The adjusted average yearly compound annual growth rate was -1.93% (standard deviation 0.92). Only 1 procedure showed an increase in reimbursement (image-guided fine-needle aspiration, +32%). CONCLUSION: Inflation-adjusted Medicare reimbursement rates for endocrine surgical procedures have consistently declined. Stakeholders must address these trends to ensure access to quality surgical endocrine care in an evolving health care landscape.

RESUMEN

Chaperonin-containing TCP-1 (CCT or TRiC) is a multi-subunit complex that folds many of the proteins essential for cancer development. CCT is expressed in diverse cancers and could be an ideal therapeutic target if not for the fact that the complex is encoded by eight distinct genes, complicating the development of inhibitors. Few definitive studies addressed the role of specific subunits in promoting the chaperonin's function in cancer. To this end, we investigated the activity of CCT2 (CCTß) by overexpressing or depleting the subunit in breast epithelial and breast cancer cells. We found that increasing total CCT2 in cells by 1.3-1.8-fold using a lentiviral system, also caused CCT3, CCT4, and CCT5 levels to increase. Likewise, silencing cct2 gene expression by ~50% caused other CCT subunits to decrease. Cells expressing CCT2 were more invasive and had a higher proliferative index. CCT2 depletion in a syngeneic murine model of triple negative breast cancer (TNBC) prevented tumor growth. These results indicate that the CCT2 subunit is integral to the activity of the chaperonin and is needed for tumorigenesis. Hence CCT2 could be a viable target for therapeutic development in breast and other cancers.

RESUMEN

Alzheimer's disease (AD) is histopathologically characterized by the build-up of fibrillar amyloid beta (Aß) in the form of amyloid plaques and the development of intraneuronal neurofibrillary tangles consisting of aggregated hyperphosphorylated Tau. Although amyloid fibrils were originally considered responsible for AD pathogenesis, recent convincing evidence strongly implicates soluble oligomeric Aß as the primary neurotoxic species driving disease progression. A third largely ignored pathological hallmark, originally described by Alois Alzheimer, is the presence of "adipose inclusions", suggestive of aberrant lipid metabolism. The molecular mechanisms underlying these "lipoid granules", as well as their potential link to soluble and/or fibrillar Aß remain largely unknown. Seeking to better-understand these conundrums, we took advantage of the powerful technology of multidimensional mass spectrometry-based shotgun lipidomics and an AD transgenic mouse model overexpressing mutant amyloid precursor protein (APP E693Δ-Osaka-), where AD-like pathology and neurodegeneration occur as a consequence of oligomeric Aß accumulation in the absence of amyloid plaques. Our results revealed for the first time that APP overexpression and oligomeric Aß accumulation lead to an additive global accumulation of nonesterified polyunsaturated fatty acids (PUFAs) independently of amyloid plaques. Furthermore, we revealed that this accumulation is mediated by an increase in phospholipase A2 (PLA2) activity, evidenced by an accumulation of sn-1 lysophosphatidylcholine and by MAPK-mediated phosphorylation/activation of group IV Ca2+-dependent cytosolic (cPLA2) and the group VI Ca2+-independent PLA2 (iPLA2) independently of PKC. We further revealed that Aß-induced oxidative stress also disrupts lipid metabolism via reactive oxygen species-mediated phospholipid cleavage leading to increased sn-2 lysophosphatidylcholine as well as lipid peroxidation and the subsequent accumulation of 4-hydroxynonenal. Brain histological studies implicated cPLA2 activity with arachidonic acid accumulation within myelin-rich regions, and iPLA2 activity with docosahexaenoic acid accumulation within pyramidal neuron-rich regions. Taken together, our results suggest that PLA2-mediated accumulation of free PUFAs drives AD-related disruption of brain lipid metabolism.
