Impact of Hormone Receptor Status and Tumor Subtypes of Breast Cancer in Young BRCA Carriers.

BACKGROUND: Hormone receptor expression is a known positive prognostic and predictive factor in breast cancer; however, limited evidence exists on its impact on prognosis of young patients harboring BRCA pathogenic variant (PV). PATIENTS AND METHODS: This international, multicenter, retrospective cohort study included young patients (≤40 years) diagnosed with invasive breast cancer and harboring germline PV in BRCA genes. We investigated the impact of hormone receptor status on clinical behavior and outcomes of breast cancer. Outcomes of interest (disease-free survival [DFS], breast cancer specific survival [BCSS] and overall survival [OS]) were first investigated according to hormone receptors expression (positive vs. negative), and then according to breast cancer subtype (luminal A-like vs. luminal B-like vs. triple-negative vs. HER2-positive breast cancer). RESULTS: From 78 centers worldwide, 4,709 BRCA carriers were included, of whom 2,143 (45.5%) had hormone receptor-positive and 2,566 (54.5%) hormone receptor-negative breast cancer. Median follow-up was 7.9 years. The rate of distant recurrences was higher in patients with hormone receptor-positive disease (13.1% vs. 9.6%, p<0.001), while the rate of second primary breast cancer was lower (9.1% vs. 14.7%, p<0.001) compared to patients with hormone receptor-negative disease. The 8-years DFS was 65.8% and 63.4% in patients with hormone receptor-positive and negative disease, respectively. The hazard ratio of hormone receptor-positive vs. negative disease changed over time for DFS, BCSS, and OS (p<0.05 for interactions of hormone receptor status and survival time). Patients with luminal A-like breast cancer had the worst long-term prognosis in terms of DFS compared to all the other subgroups (8-years DFS: 60.8% in luminal A-like vs. 63.5% in triple-negative vs. 65.5% in HER2-positive and 69.7% in luminal B-like subtype). CONCLUSIONS: In young BRCA carriers, differences in recurrence pattern and second primary breast cancer among hormone receptor-positive vs. negative disease warrants consideration in counseling patients on treatment, follow-up, and risk-reducing surgery.

Overall symptom severity as a patient-reported outcome measure for chronic rhinosinusitis: what it reflects and how to measure it.

BACKGROUND: The objective of this study was to identify how - and to what extent - overall symptom severity (OSS) score reflects individual chronic rhinosinusitis (CRS) symptoms and whether it can be measured using alternatives to the standard visual analog scale (VAS). METHODS: CRS patients from four sites across three continents rated their OSS scores, severities of nasal obstruction, nasal drainage, decreased sense of smell, facial pain/pressure and sleep disturbance using a standard VAS, VAS with labeled tick marks at every 1 centimeter, and by writing down their OSS on a scale of 0 - 100 (which was divided by 10), all of which lead to severity scores ranging from 0 - 10 in 0.1 intervals. Quality of life was measured using the SNOT-22 and EQ-5D VAS. RESULTS: In 311 CRS patients, OSS score was significantly correlated with SNOT-22 and EQ-5D VAS. OSS score was most greatly associated with the mean of all individual symptom severity scores. From individual CRS symptoms, OSS was most greatly associated with nasal obstruction followed by nasal drainage and facial pain/pressure severities. These results held true for participants with and without nasal polyps. Measurement of OSS and individual symptom severity scores using a standard VAS, tick-marked VAS, and write-in option had near-perfect consistency. CONCLUSIONS: We demonstrate for the first time that OSS largely reflects the mean of individual CRS symptom severities, although OSS is=== most weighted by nasal obstruction severity. OSS and individual symptom severity scores can be measured using a standard VAS, tick-marked VAS or write-in prompt with near-perfect consistency.

Clinical and technical factors in endoscopic skull base surgery associated with reconstructive success.

BACKGROUND: In this study, we identified key discrete clinical and technical factors that may correlate with primary reconstructive success in endoscopic skull base surgery (ESBS). METHODS: ESBS cases with intraoperative cerebrospinal fluid (CSF) leaks at four tertiary academic rhinology programs were retrospectively reviewed. Logistic regression identified factors associated with surgical outcomes by defect subsite (anterior cranial fossa [ACF], suprasellar [SS], purely sellar, posterior cranial fossa [PCF]). RESULTS: Of 706 patients (50.4% female), 61.9% had pituitary adenomas, 73.4% had sellar or SS defects, and 20.5% had high-flow intraoperative CSF leaks. The postoperative CSF leak rate was 7.8%. Larger defect size predicted ACF postoperative leaks; use of rigid reconstruction and older age protected against sellar postoperative leaks; and use of dural sealants compared to fibrin glue protected against PCF postoperative leaks. SS postoperative leaks occurred less frequently with the use of dural onlay. Body-mass index, intraoperative CSF leak flow rate, and the use of lumbar drain were not significantly associated with postoperative CSF leak. Meningitis was associated with larger tumors in ACF defects, nondissolvable nasal packing in SS defects, and high-flow intraoperative leaks in PCF defects. Sinus infections were more common in sellar defects with synthetic grafts and nondissolvable nasal packing. CONCLUSIONS: Depending on defect subsite, reconstructive success following ESBS may be influenced by factors, such as age, defect size, and the use of rigid reconstruction, dural onlay, and tissue sealants.

Preoperative, technical, and postoperative considerations for skull base reconstruction: a practical review of critical concepts.

Despite widespread adoption and advances in endoscopic skull base surgery, with expanding indications and the ability to effectively treat larger and more complex pathologies, skull base reconstruction following tumor resection and prevention of cerebrospinal fluid leak remains a challenge for even the most seasoned of surgical teams. Mounting evidence in all areas have pushed our understanding of skull base reconstruction principles forward. In this narrative review, we summarize critical concepts and provide practical but comprehensive guiding principles on preoperative, intraoperative/technical, and postoperative management principles related to optimizing skull base reconstructive success. The goal is to provide an informative resource for skull base surgeons (both otolaryngologists and neurosurgeons) to reference regarding state-of-the-art evidence surrounding this ever-evolving topic.

Overall survival in the OlympiA phase III trial of adjuvant olaparib in patients with germline pathogenic variants in BRCA1/2 and high-risk, early breast cancer.

BACKGROUND: The randomized, double-blind OlympiA trial compared 1 year of the oral poly(adenosine diphosphate-ribose) polymerase inhibitor, olaparib, to matching placebo as adjuvant therapy for patients with pathogenic or likely pathogenic variants in germline BRCA1 or BRCA2 (gBRCA1/2pv) and high-risk, human epidermal growth factor receptor 2-negative, early breast cancer (EBC). The first pre-specified interim analysis (IA) previously demonstrated statistically significant improvement in invasive disease-free survival (IDFS) and distant disease-free survival (DDFS). The olaparib group had fewer deaths than the placebo group, but the difference did not reach statistical significance for overall survival (OS). We now report the pre-specified second IA of OS with updates of IDFS, DDFS, and safety. PATIENTS AND METHODS: One thousand eight hundred and thirty-six patients were randomly assigned to olaparib or placebo following (neo)adjuvant chemotherapy, surgery, and radiation therapy if indicated. Endocrine therapy was given concurrently with study medication for hormone receptor-positive cancers. Statistical significance for OS at this IA required P < 0.015. RESULTS: With a median follow-up of 3.5 years, the second IA of OS demonstrated significant improvement in the olaparib group relative to the placebo group [hazard ratio 0.68; 98.5% confidence interval (CI) 0.47-0.97; P = 0.009]. Four-year OS was 89.8% in the olaparib group and 86.4% in the placebo group (Δ 3.4%, 95% CI -0.1% to 6.8%). Four-year IDFS for the olaparib group versus placebo group was 82.7% versus 75.4% (Δ 7.3%, 95% CI 3.0% to 11.5%) and 4-year DDFS was 86.5% versus 79.1% (Δ 7.4%, 95% CI 3.6% to 11.3%), respectively. Subset analyses for OS, IDFS, and DDFS demonstrated benefit across major subgroups. No new safety signals were identified including no new cases of acute myeloid leukemia or myelodysplastic syndrome. CONCLUSION: With 3.5 years of median follow-up, OlympiA demonstrates statistically significant improvement in OS with adjuvant olaparib compared with placebo for gBRCA1/2pv-associated EBC and maintained improvements in the previously reported, statistically significant endpoints of IDFS and DDFS with no new safety signals.

Individual symptom visual analogue scale severity scores for determining EPOS guideline-based chronic rhinosinusitis disease control.

BACKGROUND: The goal of this study was to determine how to translate visual analogue scale (VAS) symptom scores to the binary, descriptive symptom scales used in the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) criteria for chronic rhinosinusitis (CRS) disease control. METHODS: 309 CRS patients were recruited. All patients rated their burden of 5 symptoms (nasal blockage, rhinorrhea/postnasal drip, facial pain/pressure, smell loss, sleep disturbance or fatigue) using the binary EPOS descriptive symptom scales and a VAS (on a scale of 0 to 10). In addition, participants completed a 22-item Sinonasal Outcome Test (SNOT-22) and rated their overall CRS disease control as "controlled", "partly controlled" or "uncontrolled" Results: Symptom burdens measured by VAS, binary descriptive EPOS scale and SNOT-22 were associated with worsening CRS disease control reported by participants. Each symptom had a distinct VAS score cut-off that strongly predicted the uncontrolled option on the corresponding binary descriptive EPOS symptom scale. However, the predictive ability of VAS for rhinorrhea/ postnasal drip was disparately worse than the other 4 symptoms. When considering all symptom data simultaneously, a VAS score higher than 3.5 strongly predicted the uncontrolled option on the corresponding binary descriptive EPOS symptom scale for all 5 symptoms. CONCLUSIONS: A VAS symptom score of higher than 3.5 translates to the uncontrolled option in the binary, descriptive symptom scale of the EPOS control criteria. The rhinorrhea/postnasal drip descriptive symptom scale translates disparately worse to VAS scores and may be considered for revision in future criteria.

Discordance of chronic rhinosinusitis disease control between EPOS guidelines and patient perspectives identifies utility of patient-rated control assessment.

BACKGROUND: The objective of this study was to determine concordance of patient-reported chronic rhinosinusitis (CRS) disease control with CRS disease control assessed according to European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) criteria. METHODS: In 421 participants, CRS disease control was determined using EPOS criteria which include the burden of 5 symptoms measured on a binary scale, use of rescue medications in the prior 6 months and presence of diseased mucosa on nasal endoscopy. Symptom severity was also assessed using a visual analogue scale (VAS). Participants rated their CRS disease control as "controlled","partly controlled" or "uncontrolled". RESULTS: Patient-reported and EPOS-based CRS disease control ratings agreed for 49.6% of participants. Amongst cases of disagreement, EPOS guidelines assessed worse CRS disease control relative to 92.9% of patients. Facial pain/pressure and impaired sense of smell distinctly associated with patient agreement with EPOS guidelines on having "uncontrolled" CRS. Higher VAS symptom scores were associated with worse patient-reported CRS disease control (i.e., agreeing with EPOS guidelines). Removal of the nasal endoscopy criterion improved agreement between patients' and EPOS control assessments, and replacement of this criterion with patient-reported control further aligned EPOS guidelines with patient perspectives. CONCLUSIONS: EPOS guidelines regularly assess worse CRS control than assessed by patients. The lack of more gradated symptom severity criteria and inclusion of nasal endoscopy may contribute to discordance of EPOS guidelines with patient-reported CRS control. Replacement of nasal endoscopy findings with a measure of patient-reported CRS disease control better aligns EPOS CRS disease control guidelines with patients' perspectives.

Disease control in chronic rhinosinusitis: a qualitative study of patient perspectives.

BACKGROUND: The definition of disease control in chronic rhinosinusitis (CRS) is an active area of study. However, investigations have not engaged CRS patients in how they think about disease control. This study seeks to understand the patient perspective on CRS disease control. METHODS: Qualitative phenomenological study using constant comparative methodology was applied. The research team conducted 10, one-on-one interviews with CRS patients ranging from 22 to 55 minutes in length. The content of the interview protocol was determined through iterative discussion amongst all authors. Two authors served as coders to identify recurrent themes. Themes were analyzed for meaning and conclusions were summarized. RESULTS: Three recurring themes determined from patients were that (1) use of the terminology control adequately represents this phenomenon, (2) components of control could be classified into four main themes relating to CRS symptomatology, exacerbation of comorbid disease, quality of life and acute exacerbations of CRS, and (3) when patients deem their CRS is uncontrolled they are more willing to escalate their treatment to include escalating their daily maintenance regimen, seeking otolaryngology referral, taking rescue medication or undergoing endoscopic sinus surgery. CONCLUSIONS: CRS patients consider their daily symptoms, the severity and frequency of CRS exacerbations, impact on quality of life as well as exacerbation of comorbid disease when thinking about their disease control. Disease control is a goal of treatment for patients and uncontrolled disease motivates patients to seek further treatment. Physicians should explore all components of CRS control when considering disease status and need for further treatment.

Strategies for antimicrobial peptide coatings on medical devices: a review and regulatory science perspective.

Indwelling and implanted medical devices are subject to contamination by microbial pathogens during surgery, insertion or injection, and ongoing use, often resulting in severe nosocomial infections. Antimicrobial peptides (AMPs) offer a promising alternative to conventional antibiotics to reduce the incidence of such infections, as they exhibit broad-spectrum antimicrobial activity against Gram-negative and Gram-positive bacteria, microbial biofilms, fungi, and viruses. In this review-perspective, we first provide an overview of the progress made in this field over the past decade with an emphasis on the local release of AMPs from implant surfaces and immobilization strategies for incorporating these agents into a wide range of medical device materials. We then provide a regulatory science perspective addressing the characterization and testing of AMP coatings based on the type of immobilization strategy used with a focus on the US market regulatory niche. Our goal is to help narrow the gulf between academic studies and preclinical testing, as well as to support a future literature base in order to develop the regulatory science of antimicrobial coatings.

Practices and perspectives of primary care physicians in Japan and the United States about diagnosing dementia: a qualitative study.

BACKGROUND: While dementia is a common problem in Japan and the US, primary care physicians' practices and perspectives about diagnosing dementia in these different healthcare systems are unknown. METHODS: Qualitative research was conducted in an ethnographic tradition using semi-structured interviews and thematic analysis in primary care settings across Japan and in the Midwest State of Michigan, US. Participants were a total of 48 primary care physicians, 24 each from Japan and the US participated. Both groups contained a mixture of geographic areas (rural/urban), gender, age, and years of experience as primary care physicians. RESULTS: Participants in Japan and the US voiced similar practices for making the diagnosis of dementia and held similar views about the desired benefits of diagnosing dementia. Differences were found in attitudes about the appropriate timing of formally diagnosing dementia. Japanese physicians tended to make a formal diagnosis when problems that would benefit from long-term care services emerged for family members. US physicians were more proactive in diagnosing dementia in the early stages by screening for dementia in health check-ups and promoting advance directives when the patients were still capable of decision-making. Views about appropriate timing of diagnostic testing for dementia in the two systems reflect what medical or nursing care services physicians can use to support dementia patients and caregivers. CONCLUSIONS: Benefits of making the diagnosis included the need to activate the long-term care services in Japan and for early intervention and authoring advance directives in the US. Testing to establish an early diagnosis of dementia by primary care physicians only partly relates to testing and treatment options available. Benefits of making the diagnosis included the need to activate the long-term care services in Japan and for early intervention and authoring advance directives in the US.

Patient-reported chronic rhinosinusitis disease control is a valid measure of disease burden.

BACKGROUND: Disease control is an important treatment goal for chronic uncurable conditions such as chronic rhinosinusitis (CRS). The objective of this study was to determine whether patient-reported CRS disease control is a valid reflection of disease burden. METHODS: Prospective longitudinal study of 300 CRS patients (35% CRS with nasal polyps, 65% CRS without nasal polyps). At enrollment and at a subsequent follow-up timepoint, all participants were asked to rate their CRS disease control as 'not at all', 'a little', 'somewhat', 'very', 'completely' as well as to complete a 22-item Sinonasal Outcome Test (SNOT-22) and the 5-dimension EuroQol general health questionnaire from which the visual analogue scale (EQ-5D VAS) was used. RESULTS: At enrollment and follow-up timepoints, patient-reported CRS disease control was significantly correlated with SNOT-22 and EQ-5D VAS scores. The change in patient-reported CRS disease control was significantly correlated with change in SNOT-22 and change in EQ-5D VAS scores. There was significant cross-sectional and longitudinal correlation between patient-reported control and all SNOT-22 subdomain scores. A SNOT-22 score of ≤25 points or lower, or an EQ-5D VAS score of ≥77 was predictive of having well - (i.e. 'very' or 'completely') controlled CRS. CONCLUSIONS: Patient-reported CRS disease control is a valid measure of CRS disease burden and general QOL. A patient-reported assessment of CRS disease control could be considered as a component of a more comprehensive measure of CRS disease control.

Multi-institutional minimal clinically important difference of the 22-item Sinonasal Outcome Test in medically managed chronic rhinosinusitis.

BACKGROUND: With a rapid proliferation of clinical trials to study novel medical treatments for CRS, the objective of this study was to study the minimal clinically important difference (MCID) of the 22-item Sinonasal Outcome Test (SNOT-22) in medically-managed CRS patients. METHODS: A total of 183 medically-treated CRS patients were recruited. All patients completed a SNOT-22 at enrollment and subsequent follow up visit. Distribution and anchor-based methods were used for MCID calculation. These data were combined with data from a previously published study on SNOT-22 MCID in 247 medically managed CRS patients to determine a final recommended MCID value using the combined cohort of 430 patients. RESULTS: In our cohort, distribution- and anchor-based methods -"using both sinus-specific and general health anchors-"provided greatest support for a 12-point SNOT-22 MCID, which had approximately 55% sensitivity but 81% specificity for detecting patients explicitly reporting improvement in their sinus symptoms and general health. In the combined cohort of 430 patients, we also found greatest support for a 12-point SNOT-22 MCID, which had approximately 57% sensitivity and 81% specificity for detecting patients explicitly reporting improvement in their sinus symptoms and general health. We also find evidence that the MCID value may be higher in CRS patients without nasal polyps compared to those with nasal polyps. CONCLUSIONS: Our results - which include data from patients from two different institutions and regions - confirm a SNOT-22 MCID of 12 in medically managed CRS patients. The SNOT-22 MCID was specific but not sensitive for identifying CRS patients experiencing improvement in symptoms or general health.

Sympatric western lowland gorillas, central chimpanzees and humans are infected with different trichomonads.

We investigated intestinal trichomonads in western lowland gorillas, central chimpanzees and humans cohabiting the forest ecosystem of Dzanga-Sangha Protected Area in Central African Republic, using the internal transcribed spacer (ITS) region and SSU rRNA gene sequences. Trichomonads belonging to the genus Tetratrichomonas were detected in 23% of the faecal samples and in all host species. Different hosts were infected with different genotypes of Tetratrichomonas. In chimpanzees, we detected tetratrichomonads from 'novel lineage 2', which was previously reported mostly in captive and wild chimpanzees. In gorillas, we found two different genotypes of Tetratrichomonas. The ITS region sequences of the more frequent genotype were identical to the sequence found in a faecal sample of a wild western lowland gorilla from Cameroon. Sequences of the second genotype from gorillas were almost identical to sequences previously obtained from an anorexic French woman. We provide the first report of the presence of intestinal tetratrichomonads in asymptomatic, apparently healthy humans. Human tetratrichomonads belonged to the lineage 7, which was previously reported in domestic and wild pigs and a domestic horse. Our findings suggest that the ecology and spatial overlap among hominids in the tropical forest ecosystem has not resulted in exchange of intestinal trichomonads among these hosts.

Validity of systemic antibiotics and systemic corticosteroid usage for chronic rhinosinusitis as metrics of disease burden.

BACKGROUND: The frequencies of systemic antibiotics and oral corticosteroids taken for chronic rhinosinusitis (CRS) indicate poor CRS disease control. We sought to determine the validity and responsiveness of these metrics as reflections of CRS disease burden. METHODOLOGY: One hundred and eighty-seven patients undergoing medical management for CRS were recruited. Participants were assessed at two time points: enrollment and a follow-up appointment three to nine months later. At each time point, CRS related antibiotic and oral corticosteroid usage in the previous three months was measured, while general and disease-specific quality of life (QOL) was measured using the visual analog scale of the 5-dimension EuroQol questionnaire (EQ-5D VAS) and the 22-item Sinonasal Outcome Test (SNOT-22), respectively. RESULTS: The frequency of CRS-related antibiotics and oral corticosteroids use was cross-sectionally correlated with EQ-5D VAS and SNOT-22 at the corresponding time points. For participants reporting usage of these medications at enrollment, there was a decrease of 1 course per 3 months for both CRS-related antibiotics and oral corticosteroids. Change in CRS-related antibiotics from enrollment to follow-up was correlated with change in both EQ-5D and SNOT-22 over the same timeframe. The change in CRSrelated oral corticosteroids was correlated with change in both EQ-5D VAS and SNOT-22). These correlations were stronger in the subset of patients who had a change in these metrics over the study period. CONCLUSIONS: The frequencies of CRS-related antibiotic use and oral corticosteroid use are valid and responsive measures of CRS disease burden.

Research: Fluorescence Microscopy-Based Protocol for Detecting Residual Bacteria on Medical Devices.

Standard methods are needed to reliably and efficiently assess bacterial contamination of processed medical devices. This article demonstrates a standard operating procedure (SOP) for fluorescence microscopy-based detection of residual bacteria on medical devices (BAC-VIS). BAC-VIS uses a 4',6-diamidino-2-phenylindole (DAPI) stain with fluorescent microscopy to quickly and cost-effectively detect bacterial contamination of processed medical device parts. The BAC-VIS protocol was optimized and achieved greater than 80% staining efficiency and a signal-to-noise ratio of more than 20 using four representative organisms. The SOP was first validated for use on a buildup biofilm model, accessory channels of contaminated clinically used devices, and inoculated endoscope end caps and O-rings. The buildup biofilm model was used to evaluate BAC-VIS after repeated treatment of adherent bacteria with three common high-level disinfectants: glutaraldehyde, ortho-phthalaldehyde, and peracetic acid. Next, BAC-VIS was used to assess clinically used endoscope parts that cultured positive for Gram-negative bacteria. DAPI-stained cells were found on all culture-positive devices, especially in grooves and imperfections on the surface. Finally, BAC-VIS was used to detect bacteria on inoculated endoscope device components. The results showed potential for BAC-VIS to be a valuable tool for industry and academic/medical researchers for investigations of contaminated medical devices. Results obtained using BAC-VIS can increase understanding of the role of design in cleanability, wear, and prevention of contamination and may lead to improvements in materials and design that could make processed endoscope use safer for patients. Of note, this protocol is not for detecting bacteria on scopes or scope parts that will be put back into clinical use.

TRAIL responses are enhanced by nuclear export inhibition in osteosarcoma.

Tumour necrosis factor-related apoptosis inducing ligand (TRAIL) is a promising anti-tumour agent that induces apoptosis of malignant cells through activation of death receptors. Death receptor agonistic antibodies are in clinical trials as TRAIL-mimetics, however, along with TRAIL monotherapy, there is limited efficacy due to the rapid emergence of TRAIL resistance, or due to existing TRAIL-insensitive disease. TRAIL-sensitisers, which enhance TRAIL activity or overcome TRAIL resistance, may facilitate death receptor agonists as viable anti-tumour strategies. In this study we demonstrate that the nuclear export inhibitor Leptomycin B, is a potent in vitro TRAIL-sensitiser in osteosarcoma cell lines. Leptomycin B works synergistically with both TRAIL and death receptor 5 agonistic antibodies to induce apoptosis in TRAIL sensitive cell lines. Further, Leptomycin B sensitises TRAIL-insensitive cell lines to TRAIL and death receptor agonistic antibody mediated apoptosis. We also confirmed that aldehyde dehydrogenase (ALDH) positive cells are not resistant to the apoptotic effects of TRAIL and Leptomycin B, an important observation since ALDH positive cells can have enhanced tumorigenicity and are implicated in disease recurrence and metastasis. The nuclear export pathway in combination with death receptor agonists, is a potential therapeutic strategy in osteosarcoma and warrants further research on clinically relevant selective inhibitors of nuclear export.

Using all-payer claims data for health surveillance of people with intellectual and developmental disabilities.

BACKGROUND: To address limitations and challenges associated with current health surveillance of people with intellectual and developmental disabilities (IDD), this study investigates the use of all-payer claims data to identify and characterise this population. METHOD: All-payer claims data from 2010 to 2014 were used to study people with IDD in New Hampshire. Starting with the Centers for Medicare and Medicaid Services' algorithm, IDD was defined using ICD-9 diagnosis codes. Additional ICD-9 codes for developmental disabilities were included to build the knowledge base begun by recent research conducted on Medicaid claimants in five other states. RESULTS: Findings showed the enhanced algorithm offers a replicable and feasible way to conduct health surveillance of people with IDD at the state level. CONCLUSION: Substantive and significant differences between Medicaid and commercial claimants suggest that using all-payer claims provides a richer and more complete method for health surveillance of people with IDD.

Quality of life impairment due to chronic rhinosinusitis in asthmatics is mediated by asthma control.

BACKGROUND: Chronic rhinosinusitis (CRS) and asthma, when comorbid, may influence each other’s disease course and decrease quality of life (QOL). Our objective was to determine if poorer asthma control due to CRS symptoms could be a mechanism for decreased QOL in asthmatic CRS patients. METHODS: A total of 120 asthmatic CRS patients were recruited. CRS symptom burden was measured using the 22-item Sinonasal Outcome Test (SNOT-22) and patient-reported CRS symptom control, general health-related QOL was measured using the visual analog scale of the 5-dimensional EuroQol quality of life survey (EQ-5D VAS), and asthma control was measured using the Asthma Control Test (ACT). Association was sought between these outcome measures. A mediation model was created and validated to show that asthma control mediated the association between CRS symptom burden and decreased general health-related QOL. RESULTS: ACT score was associated with SNOT-22, EQ-5D VAS was associated with SNOT-22 score, and EQ-5D VAS was associated with ACT score. A statistically significant mediation effect for ACT score in the association between SNOT-22 and EQ-5D VAS), which represented 22.1% of the total effect of SNOT-22 on EQ-5D VAS, was identified. Similar findings were made for patientreported CRS symptom control instead of SNOT-22 score. CONCLUSIONS: In asthmatic CRS patients, a sizeable portion of CRS impact on QOL is indirectly mediated through the effect of CRS on poorer asthma control which may then drive decreased QOL.

Responsiveness and minimal clinically important difference for the EQ-5D in chronic rhinosinusitis.

BACKGROUND: The 5-dimensional EuroQol questionnaire (EQ-5D) is validated to measure general health-related quality of life (QOL). Our objective was to determine the responsiveness and minimal clinically important difference (MCID) of the EQ-5D health utility value (EQ-5D HUV) and visual analog scale (EQ-5D VAS) in chronic rhinosinusitis (CRS). METHODS: 203 adults undergoing medical management for CRS were prospectively recruited. General health-related QOL (using EQ-5D HUV and EQ-5D VAS) and CRS-specific QOL (using the 22-item Sinonasal Outcome Test [SNOT-22]) were measured at enrollment and a subsequent follow-up time point 2-12 months later. At follow-up, participants also rated change in general health as Much worse, A little worse, About the same, A little better or Much better compared to enrollment. The EQ-5D HUV and EQ-5D VAS MCIDs were calculated using distribution-based, anchor-based, and receiver operator characteristic (ROC) curve-based methods. RESULTS: Change in SNOT-22 score was correlated with EQ-5D HUV and EQ-5D VAS change. Using the different methods of calculating MCID, we find the EQ-5D HUV MCID to be 0.04 and EQ-5D VAS MCID to be 8.0. The calculated EQ-5D MCIDs had approximately a sensitivity of 40-50% and specificity of 80% in detecting patients experiencing noticeable improvement in general health. CONCLUSIONS: The EQ-5D responds well to changing CRS symptomatology. We propose MCIDs for EQ-5D HUV of 0.04 and EQ-5D VAS of 8 in CRS patients, which although specific, are not sensitive for detecting patients experiencing improvement in general health.
