ß-hydroxybutyrate is a metabolic regulator of proteostasis in the aged and Alzheimer disease brain.

Loss of proteostasis is a hallmark of aging and Alzheimer disease (AD). Here, we identify ß-hydroxybutyrate (ßHB), a ketone body, as a regulator of protein solubility in the aging brain. ßHB is a small molecule metabolite which primarily provides an oxidative substrate for ATP during hypoglycemic conditions, and also regulates other cellular processes through covalent and noncovalent protein interactions. We demonstrate ßHB-induced protein insolubility across in vitro, ex vivo, and in vivo mouse systems. This activity is shared by select structurally similar metabolites, is not dependent on covalent protein modification, pH, or solute load, and is observable in mouse brain in vivo after delivery of a ketone ester. Furthermore, this phenotype is selective for pathological proteins such as amyloid-ß, and exogenous ßHB ameliorates pathology in nematode models of amyloid-ß aggregation toxicity. We have generated a comprehensive atlas of the ßHB-induced protein insolublome ex vivo and in vivo using mass spectrometry proteomics, and have identified common protein domains within ßHB target sequences. Finally, we show enrichment of neurodegeneration-related proteins among ßHB targets and the clearance of these targets from mouse brain, likely via ßHB-induced autophagy. Overall, these data indicate a new metabolically regulated mechanism of proteostasis relevant to aging and AD.

Analysis of microbial keratitis incidence, isolates and in-vitro antimicrobial susceptibility in the East of England: a 6-year study.

BACKGROUND/OBJECTIVES: To report the incidence, microbiological profile and in-vitro antimicrobial susceptibilities of microbial keratitis (MK) in the East of England (EoE) over a 6-year period. SUBJECTS/METHODS: A retrospective study of patients diagnosed with MK who underwent corneal scraping at participating trusts, within the EoE, between 01/01/2015-01/07/2020. Analysis was performed on MK isolate profiles, in-vitro anti-microbial sensitivities and trends over time. RESULTS: The mean incidence of IK, in the EoE, was estimated at 6.96 per 100 000 population/year. 1071 corneal scrapes were analysed, 460 were culture positive (42.95%) of which 87.2% were bacteria (50.3% gram-positive and 49.7% gram-negative), 2.4% polymicrobial, 9.3% fungi and 1.1% acanthamoeba. The most common organisms were pseudomonas spp (29.57%). There was a non-statistically significant trend (NST) in increasing incidence of pseudomonas spp, staph aureus and serratia (p = 0.719, p = 0.615, and p = 0.099 respectively) and a declining NST in Fungi (p = 0.058). Susceptibilities in-vitro to, penicillin classes, fluoroquinolone and aminoglycosides were 76.7% and 89.4%, 79.2% and 97.2% and 95.4 and 96.1% to gram-positive and gram-negative bacteria respectively. Gram-negative organisms were increasingly resistant to cephalosporins with a 19.2% reduction in sensitivity over time. (p = 0.011). Ceftriaxone showed the greatest decrease in sensitivity of 41.67% (p = 0.006). CONCLUSION: In the EoE, MK is relatively prevalent though likely underestimated. Profiles are similar to other UK regions with the exception of a higher fungal and lower acanthamoeba incidence. Common first and second-line antimicrobial selection provides, on the whole, good coverage. Nevertheless, anti-microbial resistance, to cephalosporins, was observed so selection should be carefully considered when treating MK empirically.

Spectrum of intracranial and spinal epidermoids including unusual locations and imaging findings: A pictorial review.

Intracranial and spinal epidermoids are benign slow-growing congenital lesions. They are predominantly intradural, extra-axial in location, with intra-axial locations (intra-parenchymal and spinal intramedullary) being rare. The most common locations of intradural epidermoids are cerebellopontine angle cistern followed by supra- and para-sellar regions, and fourth ventricle. Less common locations include inter-hemispheric fissure, sylvian fissure, lateral ventricle, intracerebral, velum interpositum cistern, superior cerebellar cistern and pineal gland. They can also be extradural, usually arising in the diploic space of the calvaria, though they are less common. Magnetic resonance imaging is the primary modality for diagnosis and knowing the extent of the lesion. In this pictorial review, we intend to illustrate their classical and unusual locations, atypical imaging findings including calcifications, rare complications like haemorrhage or spontaneous rupture.

A Randomized Controlled Trial Comparing Microthin Descemet Stripping Automated Endothelial Keratoplasty With Descemet Membrane Endothelial Keratoplasty: Two-Year Report.

PURPOSE: The purpose of this study was to report the 2-year outcomes of a double-blinded randomized controlled trial comparing Descemet membrane endothelial keratoplasty (DMEK) and microthin Descemet stripping automated endothelial keratoplasty (MT-DSAEK). METHODS: Fifty-six eyes of 56 patients were randomized to DMEK or microthin DSAEK (MT-DSAEK). The main outcome measure was best spectacle-corrected visual acuity (BSCVA) at 24 months. Other secondary outcomes included complications, endothelial cell density, and vision-related quality-of-life (vQoL) scores. RESULTS: There was no statistically significant difference in BSCVA between the DMEK and MT-DSAEK groups at the 2-year time point (mean ± SD; 0.04 ± 0.14 vs. 0.12± 0.19, P = 0.061) in contrast to the 1-year results (mean ± SD; 0.04 ± 0.13 vs. 0.11 ± 0.09, P = 0.002) previously reported. Endothelial cell density did not show a statistically significant difference at 24 months between the DMEK and MT-DSAEK groups (1522 ± 293 cell/mm2 vs. 1432 ± 327 cells/mm2, P = 0.27). There were 2 additional graft rejection episodes in the MT-DSAEK group between the 1- and 2-year follow-up periods, but this did not result in graft failure. The mean vQoL scores between DMEK and MT-DSAEK indicated similar patient satisfaction between the groups (97.1 ± 4.0 vs. 92.6 ± 10.2, P = 0.13). CONCLUSIONS: In summary, the trial showed no significant difference in BSCVA at 24 months between the DMEK and MT-DSAEK groups. Both techniques continued to demonstrate comparable outcomes for complication rates, endothelial cell loss, and patient-reported vQoL scores. TRIAL REGISTRATION: ISRCTN10578843.

Occurrence of Banana bract mosaic virus on Musa ornata Roxb based hybrids in India.

Musa ornata, wild species of banana is being used as a cut flower, potted plants and for landscape gardening etc., They are also being utilized in banana hybridization programmes for introgressing pest and disease tolerant traits into banana cultivars in addition to the development of inter specific ornamental banana hybrids. Symptoms of banana bract mosaic virus (BBrMV) was observed in the bracts of interspecific M. ornata based hybrid developed using another wild species i.e., Musa rubra Kurz at ICAR-National Research Centre for Banana (NRCB), Tiruchirapalli. Presence of the virus in the bracts, leaves and roots of symptomatic plants was confirmed through triple antibody sandwich enzyme linked immunosorbent assay with BBrMV monoclonal and polyclonal antibodies. BBrMV HC-Pro (1370 bp), CP (900 bp) and VPg (570 bp) genes were amplified from the infected bracts using reverse transcriptase polymerase chain reaction with BBrMV respective gene primers. The amplicons of these three genes were cloned and sequenced. Blastn analysis revealed that HC-Pro, VPg and CP gene sequences has 97.67%, 97.72% and 99.67% similarity with the respective gene sequences of BBrMV infecting banana. Phylogenetic analysis clustered the test isolate with other BBrMV isolates of banana and other hosts based on CP and HC-Pro and VPg gene sequences. The virus is transmitted through Pentalonia nigronervosa and the transmitted plants expressed symptoms under glass house conditions. To the best of our knowledge, this is the first report of BBrMV on ornamental M. ornata hybrid in India and its transmission occurs through Pentalonia nigronervosa.

Asthma-chronic obstructive pulmonary disease overlap and cost-related medication non-adherence among older adults in the United States.

BACKGROUND: Cost-related medication non-adherence (CRN) can negatively impact health outcomes in older adults with asthma and chronic obstructive pulmonary disease (COPD) overlap (ACO) by reducing access and adherence to essential medications. The objective of this study is to examine the association of ACO to any CRN and specific forms of CRN among a nationally representative sample of older (age ≥ 65 years) adults. METHODS: We adopted a cross-sectional study design using data from pooled cross-sectional Medicare Current Beneficiary Surveys (MCBS) (2006-2013) and linked fee-for-service Medicare claims. Unadjusted and adjusted logistic regressions that accounted for the complex survey design examined the association of ACO to any CRN and specific forms of CRN. RESULTS: Among older adults with ACO, 16% reported any CRN. The most common form of CRN was "failing to get prescription". As compared to older adults with no asthma and no COPD, those with ACO were more likely to report any CRN (adjusted odds ratios [AOR] = 1.50, 95%CI = [1.14, 1.96]) and all forms of CRN. However, when the number of unique medications was added to the model, there were no statistically significant differences in CRN between the two groups. CONCLUSIONS: Older adults with ACO represent a vulnerable population with increased risk for CRN. Multiple factors can contribute to CRN including: a higher number of prescribed medications, multiple co-morbidities, and cost of therapies. Medication comprehensive review interventions have the potential of reducing the risk of CRN among the older Medicare beneficiaries with ACO.

Initial maintenance therapy adherence among older adults with asthma-COPD overlap.

OBJECTIVES: To examine the impact of initial maintenance therapy (IMT) type (inhaled corticosteroid [ICS] vs fixed-dose combination of ICS and long-acting ß agonist [ICS/LABA]) on trajectories of adherence among older adults (≥ 65 years) with coexisting asthma and chronic obstructive pulmonary disease (COPD), known as asthma-COPD overlap (ACO). STUDY DESIGN: We used a longitudinal, retrospective cohort design. METHODS: This study used a cohort of older adults with ACO using longitudinal data from a 10% sample of Optum's Deidentified Clinformatics Data Mart. We adopted group-based trajectory modeling to identify medication adherence trajectories over 12 months. Multinomial logistic regressions were used to evaluate the unadjusted and adjusted associations of IMT medication and adherence trajectory categories. All analyses accounted for treatment option selection bias with inverse probability treatment weighting. RESULTS: Of 1555 individuals, 73% of the sample used ICS/LABA for IMT. Four medication adherence trajectories were observed regardless of regimen: (1) persistent high adherence (12.0%), (2) progression to high adherence (20.8%), (3) progression to low adherence (10.5%), and (4) persistent low adherence (56.7%). Those who were initiated on ICS/LABA were less likely to have persistent low adherence (unadjusted odds ratio [OR], 0.44; 95% CI, 0.29-0.67) compared with those initiated on ICS monotherapy when "persistent high adherence" was used as the reference group. The relationship remained significant in adjusted regressions (adjusted OR, 0.38; 95% CI, 0.24-0.59). CONCLUSIONS: Real-world evidence suggests that using ICS/LABA for IMT may decrease the likelihood of persistent low adherence over time among older adults with ACO compared with ICS monotherapy.

Determining the Entrepreneurial and Intrapreneurial Intentions of Student Pharmacists in Iran.

Objective. To identify factors and entrepreneurial characteristics associated with entrepreneurial and intrapreneurial intentions among Doctor of Pharmacy (PharmD) students in Iran.Methods. First, the Entrepreneurial-Intrapreneurial Pharmacist Questionnaire (EIPQ), which was developed in the United States, was translated from English to Persian. The paper-based Persian-EIPQ questionnaire was then tested in a convenience sample of student pharmacists enrolled in pharmacy schools in Iran. The entrepreneurial characteristics questionnaire was evaluated using exploratory factor analysis with varimax rotation. Internal consistency was examined using Cronbach alpha. The association of demographics and educational variables and entrepreneurial characteristics with entrepreneurial and intrapreneurial intentions was determined using a multiple linear regression model.Results. A total of 504 surveys, 98.6% of the completed questionnaires received, were analyzed. A majority of the participants were female (75.8%) and from 18 to 25 years old (92.2%). Entrepreneurial intention had a positive and significant association with risk-taking propensity, leadership self-efficacy, autonomy, achievement motivation, and having an entrepreneur in the family. Intrapreneurial intention had a positive and significant association with risk-taking propensity, leadership self-efficacy, achievement motivation, people liking, attending a private school, and having an entrepreneur in the family.Conclusion. Based on the findings, student pharmacists with higher levels of risk-taking propensity, achievement motivation, leadership self-efficacy, autonomy, and people liking may be more likely to have greater levels of entrepreneurial and/or intrapreneurial intention.

Diagnostic and management challenges of intraventricular neurocysticercosis presenting in the third trimester of pregnancy: A case report.

The diagnosis of neurocysticercosis in pregnancy is challenging, even in endemic areas, as other neurological conditions with similar manifestations are common. Obstetricians and physicians may be reluctant to do neuroimaging in pregnancy and often the availability is limited in endemic areas. Management of neurocysticercosis depends on the symptomatology. In those presenting with features of increased intracranial pressure early treatment is necessary, taking into consideration the gestational age and the maternal condition at presentation. Presence of intraventricular cysts causing obstructive hydrocephalus necessitates their removal due to the risk of intracranial hypertension which could be life-threatening, particularly peripartum. We report a case of a woman with intraventricular neurocysticercosis, who presented in the third trimester, and described the management dilemmas that were encountered. The differential diagnoses and other aspects of the medical and surgical management of neurocysticercosis in pregnancy are also discussed.

Maternal finger-prick allogenic blood for persistent corneal epithelial defects.

This is a case of a 17-year-old patient with aniridia-related keratopathy and persistent epithelial defect (PED) treated successfully using maternal finger-prick blood (FPB). Maternal allogenic FPB treatment was initiated to the patient who was non-compliant with the use of autologous FPB. The PED was successfully managed with maternal FPB treatment with rapid and complete closure of the epithelial defect. Additionally, there was immediate and sustained symptomatic improvement to pain and recovery of vision in the only seeing eye. There was no immunological reaction to allogenic blood. Maternal finger-prick allogenic blood could serve as a potential alternative to serum eye drops or autologous FPB in the management of refractory PED, particularly in reference to the paediatric or the vulnerable age group. Further studies are required to confirm the role of allogenic blood in the treatment of PED.

Economic Burden of Asthma-Chronic Obstructive Pulmonary Disease Overlap among Older Adults in the United States.

The objective of this study is to estimate the excess economic burden of Asthma-COPD Overlap (ACO) among older adults in the United States. We used a cross-sectional study design with data from a nationally representative survey of Medicare beneficiaries (Medicare Current Beneficiary Survey) linked to Medicare fee-for-service claims. Older adults with ACO had higher average total healthcare expenditures ($45,532 vs. $12,743) and higher out-of-pocket spending burden (19% vs. 8.5%) compared to those with no-asthma no-COPD (NANC). Individuals with ACO also had almost two, and 1.5 times higher expenditures compared to individuals with asthma only and COPD only, respectively. Multivariable regression models indicated that the adjusted associations of ACO to economic burden remained positive and statistically significant. In comparison with NANC, nearly three-quarters of the excess total healthcare expenditures and 83% of the out-of-pocket spending burden of older adults with ACO were explained by differences in predisposing, enabling, need, personal healthcare practices, and external factors among the two groups. The higher number of unique medications and the increased incidence of fragmented care were the leading contributors to the excess economic burden among older adults with ACO comparing to NANC individuals. Interventions that reduce the number of medications and fragmented care have the potential to reduce the excess economic burden among older adults with ACO.

Microthin Descemet Stripping Automated Endothelial Keratoplasty Versus Descemet Membrane Endothelial Keratoplasty: A Randomized Clinical Trial.

PURPOSE: To compare visual outcomes, complications, and vision-related quality of life (QoL) after microthin Descemet stripping automated endothelial keratoplasty (MT-DSAEK) versus Descemet membrane endothelial keratoplasty (DMEK) for the management of corneal endothelial dysfunction in Fuchs dystrophy. METHODS: This is a prospective, double-blinded randomized controlled clinical trial. Patients with visually significant endothelial decompensation from Fuchs dystrophy were prospectively randomized to receive MT-DSAEK or DMEK surgery. The primary outcome was best spectacle-corrected visual acuity (BSCVA) at 12 months. Secondary outcomes included refraction, keratometry, endothelial cell count, complications, and vision-related QoL at 6 and 12 months postoperatively. RESULTS: A total of 56 eyes of 56 patients were enrolled, 28 in each group. Postoperatively, LogMAR mean BSCVA in the MT-DSAEK group was 0.17 ± 0.08 and 0.11 ± 0.09 at 6 and 12 months compared with 0.09 ± 0.13 and 0.04 ± 0.13 after DMEK (P = 0.03, P = 0.002 respectively) with the DMEK cohort achieving 3.5 logarithm of the minimum angle of resolution letters better BSCVA at 1 year compared with MT-DSAEK. Complication rates were similar with 3.5% rebubbling rate in both groups, 1 primary graft failure in DMEK and a single endothelial rejection in the MT-DSAEK arm. Vision-related QoL was comparable at 6 and 12 months postoperatively, and no eyes demonstrated loss of vision from preoperative BSCVA. CONCLUSIONS: DMEK surgery resulted in significantly better BSCVA at 1, 3, 6, and 12 months postoperatively compared with MT-DSAEK. Patient satisfaction was similar with no differences reported in vision-related QoL scores, as was the complications profile between groups. Thus, our results favor DMEK as the better choice procedure for eyes with Fuchs-related corneal decompensation without ocular comorbidities.

Association of Entrepreneurial Traits With Interest in Becoming a Pharmacist Provider Among Student Pharmacists.

BACKGROUND: With the emerging opportunities for pharmacists to gain provider status, the need for understanding interest to become a pharmacist provider has never been greater. OBJECTIVE: To determine which entrepreneurial traits (locus of control, innovativeness, autonomy, risk-taking propensity, proactiveness, achievement motivation, people liking, problem-solving, and leadership) are associated with interest in becoming a pharmacist provider. METHODS: A cross-sectional survey was conducted among second- and third-year student pharmacists. Exploratory factor analysis (principal components with varimax rotation) was used to determine any underlying dimensions. Significant differences in interest in becoming a pharmacist provider by demographic and other characteristics were determined using t tests and analysis of variance (ANOVA; P ≤ .05). Multiple linear regression was used to determine the factors associated with interest in becoming a pharmacist provider. RESULTS: A total of 137 completed questionnaires were received. Gender (P = .003) and preference of workplace (P < .001) were significantly associated with interest in becoming a pharmacist provider. All factor loadings were more than 0.50 and Cronbach alpha values were more than .68. In the multiple linear regression analysis model, proactiveness (P = .036) and achievement motivation (P = .018) were positive predictors of interest in becoming a pharmacist provider. Females (P = .006) and individuals who preferred to work in a hospital (P < .001) or in specialty care (P = .007) had a significantly greater interest in becoming a pharmacist provider. CONCLUSIONS: Proactiveness and achievement motivation can be predictors of interest in becoming a pharmacist provider.

Initial Validation of an Instrument for Measuring Entrepreneurial and Intrapreneurial Intentions in Student Pharmacists.

Objective. To develop a questionnaire for measuring entrepreneurial and intrapreneurial intentions among student pharmacists and to identify characteristics and personality traits that are associated with these intentions. Methods. A 105-item survey instrument was developed and administered to all Doctor of Pharmacy (PharmD) students (incoming to third year) at a large public university. It consisted of nine scales pertaining to entrepreneurism including previously validated and some newly developed scales adapted for use among student pharmacists. Data analysis consisted of factor analysis to determine scale constructs, reliability assessment, and systematic item-reduction analysis. Multiple linear regression and structural equation modeling was used to determine and confirm the association of personality traits and demographic characteristics with entrepreneurial and intrapreneurial intentions. Results. Of 289 students surveyed, 286 useable survey instruments were included in the analysis. Factor analysis was conducted for each scale, and items that did not load on their theorized factor or had cross-loadings above the permissible limits were removed, reducing the survey to 69 items. Findings demonstrated that gender, joint degree program, and autonomy were significant predictors of entrepreneurial intentions, and achievement motivation, leadership self-efficacy, and problem-solving were significant predictors of intrapreneurial intentions. Conclusion. A multi-dimensional questionnaire to measure entrepreneurial and intrapreneurial intentions of student pharmacists was developed and a few key predictors of such intentions were identified. When fully validated, the questionnaire may be used in pharmacy schools for several purposes, including in the PharmD admission process to gain additional insights into a student's potential to become a future innovative entrepreneurial or intrapreneurial practitioner.

Receipt of Guideline-Concordant Care Among Older Women With Stage I-III Breast Cancer: A Population-Based Study.

Background: This study examined receipt of guideline-concordant care (GCC) according to evidence-based treatment guidelines and quality measures and specific types of treatment among older women with breast cancer. Patients and Methods: A total of 142,433 patients aged ≥66 years diagnosed with stage I-III breast cancer between 2007 and 2011 were identified in the SEER-Medicare linked database. Algorithms considering cancer characteristics and the appropriate course of care as per guidelines versus actual care received determined receipt of GCC. Multivariable logistic regression estimated the likelihood of GCC and specific types of treatment for women aged ≥75 versus 66 to 74 years. Results: Overall, 39.7% of patients received GCC. Patients diagnosed at stage II or III, with certain preexisting conditions, and of nonwhite race were less likely to receive GCC. Patients with hormone-negative tumors, higher grade tumors, and greater access to oncology care resources were more likely to receive GCC. Patients aged ≥75 years were approximately 40% less likely to receive GCC or adjuvant endocrine therapy, 78% less likely to have any surgery, 61% less likely to have chemotherapy, and about half as likely to have radiation therapy than those aged 66 to 74 years. Conclusions: Fewer than half of older women with breast cancer received GCC, with the lowest rates observed among the oldest age groups, racial/ethnic minorities, and women with later-stage cancers. However, patients with more aggressive tumor characteristics and greater access to oncology resources were more likely to receive GCC. Considering that older women have the highest incidence of breast cancer and that many are diagnosed at stages requiring more aggressive treatment, efforts to increase rates of earlier stage diagnosis and the development of less toxic treatments could help improve GCC and survival while preserving quality of life.

Jejunojejunal intussusception: an unusual case of postoperative intestinal obstruction.

Intussusception is a rare cause for postoperative intestinal obstruction. We report a case of intussusception in the early postoperative period following resection of proximal jejunum and end to end anastomosis. Computed tomography showed jejunal intussusception, which was confirmed on exploration. The anastomotic site was acting as the lead point, which was resected after reduction and reanastomosed in a single layer. The patient had uneventful recovery. Very few similar cases are reported in the literature and all the reported cases are following free jejunal transfer for pharyngo-oesophageal reconstruction.

Feasibility Study of Human Corneal Endothelial Cell Transplantation Using an In Vitro Human Corneal Model.

PURPOSE: To test the feasibility of a cell therapy approach to treat corneal endothelial (CE) disorders using an in vitro model of human corneal decompensation. METHODS: A CE decompensation model was established by removal of the Descemet membrane/endothelium complex from cadaveric human corneas in an air interface organ culture system (group 2) and compared with normal corneas (group 1). The posterior stroma of decompensated corneas was seeded with immortalized human corneal endothelial cells (HCEC-12) in group 3 and passage 0 primary human CE cells in group 4 corneas. Functional effects on stromal thickness were determined with histological analysis 3 to 10 days after cell therapy treatment. RESULTS: Removal of the Descemet membrane/endothelium complex in group 2 corneas resulted in a stromal thickness of 903 ± 86 µm at 12 hours compared with 557 ± 72 µm in group 1 corneas. Stromal thickness reduced from 1218 ± 153 µm to 458 ± 90 µm (63% ± 6%, P = 0.001) after cell transplantation in group 3 and from 1100 ± 86 µm to 489 ± 94 µm (55% ± 7%, P = 0.00004) in group 4. Posttransplantation histology demonstrated formation of a monolayer of corneal endothelium attached to the posterior stromal surface. CONCLUSIONS: Direct transplantation of cultured human CE cells and immortalized HCEC-12 to bare posterior corneal stroma resulted in formation of an endothelial monolayer and restoration of stromal hydration to physiological thickness, demonstrating the feasibility of cell therapy in treatment of CE decompensation in a human in vitro model.

Quality indicators in a community optometrist led cataract shared care scheme.

PURPOSE: Cataract shared care schemes involving community optometrists show wide variation in practice. We report on defined key performance indicators (KPIs) which improve accountability between stakeholders. METHODS: In this prospective study over nine months at a UK public hospital, we evaluated the outcomes of consecutive direct cataract referrals from community optometrists against two KPIs agreed under a service-level agreement between the Hospital Eye Service and community optometrists: (1) 85% of patients listed for cataract listing at first consultation; and (2) 90% postoperative feedback return rate on patients discharged to community optometrists. A detailed analysis on referral triage, surgical listing and postoperative form return rate is reported in this study. RESULTS: A total of 733 direct cataract referrals were received using a designated referral form of which 86% were listed for cataract surgery. The predominant reason for not listing was a failure to reach the visual threshold set by the local clinical commissioning guidelines. Out of 569 cataract surgical episodes, 402 (71%) patients were discharged on the same day of surgery to community optometrist follow up. Completed postoperative feedback was returned from 374 patients (93%). CONCLUSION: Direct cataract referrals from accredited community optometrists led to a majority of patients receiving a definitive clinical decision during first consultation. Postoperative community follow up reduced hospital visits and allowed for convenient consultation closer to home following uncomplicated cataract surgery. A service-level agreement with an accreditation scheme measured against KPIs enhances the accountability of stakeholders involved in the cataract shared care scheme.

Association of the severity of diabetes-related complications with stage of breast cancer at diagnosis among elderly women with pre-existing diabetes.

PURPOSE: This study assessed the association between the severity of diabetes complications using diabetes complications severity index (DCSI) and stage of breast cancer (BC) at diagnosis among elderly women with pre-existing diabetes and incident BC. METHODS: Using Surveillance, Epidemiology and End Results-Medicare data, we identified women with incident BC during 2004-2011 and pre-existing diabetes (N = 7729). Chi-square tests were used to test for group differences in stage of BC at diagnosis. Multinomial logistic regression was used to examine the associations between the severity of diabetes complications and stage of BC at diagnosis. RESULTS: Overall, women with a DCSI = 2 and a DCSI ≥ 3 were more likely to be diagnosed at advanced stages as compared to those with no diabetes complications. In full adjusted association (after adding BC screening to the analysis model), the severity of diabetes complications was no longer an independent predictor of advanced stages at diagnosis. However, women with a DCSI = 2 were 26% more likely to be diagnosed at stage I (versus stage 0) of BC at diagnosis as compared to those without diabetes complications (OR 1.26, 95% CI 1.03-1.53). CONCLUSION: The increased likelihood of having advanced-stage BC at diagnosis associated with severity of diabetes-related complications appears to be mediated by lower rates of breast cancer screening among elderly women with pre-existing diabetes complications. Therefore, reducing disparity in receiving breast cancer screening among elderly women with diabetes may reduce the risk of advanced-stage breast cancer diagnosis.

Healthcare Utilization and Costs During the Initial Phase of Care Among Elderly Women With Breast Cancer.

Background: Understanding the patterns of healthcare utilization and costs during the initial phase of care (12 months after breast cancer [BC] diagnosis) in older women (aged ≥65 years) is crucial in the allocation of Medicare resources. The objective of this study was to determine healthcare utilization and costs during the initial phase of care in older, female, Medicare fee-for-service beneficiaries diagnosed with BC, and to determine the factors associated with higher costs. Methods: A retrospective observational study using the SEER-Medicare linked database was conducted in 69,307 women aged ≥66 years diagnosed with primary incident BC in 2003-2009 to determine healthcare utilization, average costs, and costs for specific services during the initial phase of care. Generalized linear model regression was conducted to identify the factors associated with higher costs in a multivariate framework. Results: A total of 96% of women were treated with surgery during the initial phase of BC care, whereas 21% and 54% underwent chemotherapy and radiotherapy, respectively. Costs during the initial phase of care totalled $28,075 in 2012 USD, comprising $13,344 for physician services and $7,456 for outpatient services. Factors associated with higher costs during the initial phase of care were younger age (66-69 years), African American race, higher household income, advanced stages of BC, initial BC treatment, higher number of primary care physician visits, and presence of comorbidities and/or a mental condition. Conclusions: The economic burden of BC is substantial during the initial phase of care. Physician and outpatient services accounted for the highest proportion of costs. Predisposing factors, need-related factors, healthcare use, and external environmental healthcare factors significantly predicted costs during the initial phase of care.
