Host JAK-STAT activity is a target of parasitoid wasp virulence strategies.

Innate immune responses that allow hosts to survive infection depend on the action of multiple conserved signaling pathways. Pathogens and parasites in turn have evolved virulence factors to target these immune signaling pathways in an attempt to overcome host immunity. Consequently, the interactions between host immune molecules and pathogen virulence factors play an important role in determining the outcome of an infection. The immune responses of Drosophila melanogaster provide a valuable model to understand immune signaling and host-pathogen interactions. Flies are commonly infected by parasitoid wasps and mount a coordinated cellular immune response following infection. This response is characterized by the production of specialized blood cells called lamellocytes that form a tight capsule around wasp eggs in the host hemocoel. The conserved JAK-STAT signaling pathway has been implicated in lamellocyte proliferation and is required for successful encapsulation of wasp eggs. Here we show that activity of Stat92E, the D. melanogaster STAT ortholog, is induced in immune tissues following parasitoid infection. Virulent wasp species are able to suppress Stat92E activity during infection, suggesting they target JAK-STAT pathway activation as a virulence strategy. Furthermore, two wasp species (Leptopilina guineaensis and Ganaspis xanthopoda) suppress phenotypes associated with a gain-of-function mutation in hopscotch, the D. melanogaster JAK ortholog, indicating that they inhibit the activity of the core signaling components of the JAK-STAT pathway. Our data suggest that parasitoid wasp virulence factors block JAK-STAT signaling to overcome fly immune defenses.

Randomized Prospective Trial of Epidural Analgesia after Open Hepatectomy.

OBJECTIVE: To evaluate whether patient-controlled epidural analgesia (PCEA) improves postoperative pain during ambulation following elective open hepatectomy. BACKGROUND: Strategies to alleviate postoperative pain are a critical element of recovery after surgery. However, the optimal postoperative pain management strategy following open hepatectomy remains unclear. METHODS: We conducted a prospective, nonblinded, randomized comparison of PCEA (intervention) versus intravenous patient-controlled analgesia (IV PCA; control) for postoperative pain following elective open hepatectomy. The primary end point was pain during ambulation on postoperative day (POD) 2. The study was powered to detect a clinically significant 2-point difference on the pain numeric rating scale (NRS). Secondary end points included pain at rest, morbidity, time to return of bowel function, and length of stay. RESULTS: From 2015 to 2020, 231 patients were randomized (116 patients in the PCEA arm and 115 in the IV PCA arm). The incidence of epidural failure was 3% (n=4/116), with no epidural-related complications. Patients in the PCEA arm had a <2-point difference in NRS pain scores during ambulation on POD 2 vs. IV PCA (median 4.0 vs. 5.0, P <0.001). There was no difference in overall complications between the PCEA and IV PCA arms (33% vs. 40%, P =0.276). Secondary outcomes, including pain scores at rest, were similar between the study arms. CONCLUSIONS: PCEA was safe following open hepatectomy and was associated with a small difference in pain with activity on POD 2 that did not reach our pre-specified definition of clinical significance.

Associations of Hearing Loss and Hearing Aid Use With Cognition, Health-Related Quality of Life, and Depressive Symptoms.

ObjectivesDetermine associations of hearing loss (HL) and hearing aid (HA) use with cognition, health-related quality of life (HRQoL), and depressive symptoms. Methods: Participants were from the Epidemiology of Hearing Loss Study or Beaver Dam Offspring Study. HL was defined as pure-tone average (.5-4.0 kHz) > 25 dB. A principal component analysis of 5 cognitive tasks measured cognition. The SF-12 measured mental and physical HRQoL. The Centers for Epidemiological Studies Depression Scale measured depressive symptoms (score ≥ 16). Regression models returned beta (B) coefficients or odds ratios (OR) with 95% confidence intervals. Results: This study included 3574 participants. HL (vs. none) was associated with poorer cognition (B-.12 [-.18, -.06]), mental (B-.99 [-1.65, -.33]) and physical (B-.76 [-1.50, -.03]) HRQoL, and increased odds of depressive symptoms (OR 1.49 [1.16, 1.91]). HA users had better cognition than non-users. Discussion: HL likely impacts cognition and well-being. HA use may have cognitive benefits.

The Reemergence of Measles.

OBJECTIVES: Present-day pathologists may be unfamiliar with the histopathologic features of measles, which is a reemerging disease. Awareness of these features may enable early diagnosis of measles in unsuspected cases, including those with an atypical presentation. Using archived tissue samples from historic patients, a unique source of histopathologic information about measles and other reemerging infectious diseases, we performed a comprehensive analysis of the histopathologic features of measles seen in commonly infected tissues during prodrome, active, and late phases of the disease. METHODS: Subspecialty pathologists analyzed H&E-stained slides of specimens from 89 patients accessioned from 1919 to 1998 and correlated the histopathologic findings with clinical data. RESULTS: Measles caused acute and chronic histopathologic changes, especially in the respiratory, lymphoid (including appendix and tonsils), and central nervous systems. Bacterial infections in lung and other organs contributed significantly to adverse outcomes, especially in immunocompromised patients. CONCLUSIONS: Certain histopathologic features, especially Warthin-Finkeldey cells and multinucleated giant cells without inclusions, allow pathologists to diagnose or suggest the diagnosis of measles in unsuspected cases.

Inflammation, metabolic dysregulation and environmental neurotoxins and risk of cognitive decline and impairment in midlife.

BACKGROUND: Age-related declines in cognitive function may begin in midlife. PURPOSE: To determine whether blood-based biomarkers of inflammation, metabolic dysregulation and neurotoxins are associated with risk of cognitive decline and impairment. METHODS: Baseline blood samples from the longitudinal Beaver Dam Offspring Study (2005-2008) were assayed for markers of inflammation, metabolic dysregulation, and environmental neurotoxins. Cognitive function was measured at baseline, 5-year (2010-2013) and 10-year (2015-2017) examinations. Participants without cognitive impairment at baseline and with cognitive data from at least one follow-up were included. Cox proportional hazards models were used to evaluate associations between baseline blood biomarkers and the 10-year cumulative incidence of cognitive impairment. Poisson models were used to estimate the relative risk (RR) of 5-year decline in cognitive function by baseline blood biomarkers. Models were adjusted for age, sex, education, and cardiovascular related risk factors. RESULTS: Participants (N = 2421) were a mean age of 49 years and 55% were women. Soluble vascular cell adhesion molecule-1 (sVCAM-1Tertile(T)3 vs T1-2 hazard ratio (HR) = 1.72, 95% confidence interval (CI) = 1.05,2.82) and hemoglobin A1C (HR = 1.75, 95% CI = 1.18,2.59, per 1% in women) were associated with the 10-year cumulative incidence of cognitive impairment. sVCAM-1 (RRT3 vs T1-2 = 1.45, 95% CI = 1.06,1.99) and white blood cell count (RR = 1.10, 95% CI = 1.02,1.19, per 103/µL) were associated with 5-year cognitive decline. CONCLUSIONS: Biomarkers related to inflammation and metabolic dysregulation were associated with an increased risk of developing cognitive decline and impairment. These results extend previous research in cognitive aging to early markers of cognitive decline in midlife, a time when intervention methods may be more efficacious.

Lifestyle and factors of vascular and metabolic health and inflammation are associated with sensorineural-neurocognitive aging in older adults.

This study's aim was to identify risk factors associated with sensorineural and neurocognitive function (brain aging) in older adults. In N = 1,478 Epidemiology of Hearing Loss Study participants (aged 64-100 years, 59% women), we conducted sensorineural and cognitive tests, which were combined into a summary measure using Principal Component Analysis (PCA). Participants with a PCA score <-1 standard deviation (SD) were considered to have brain aging. Incident brain aging was defined as PCA score <-1 SD at 5-year follow-up among participants who had a PCA score ≥-1 SD at baseline. Logistic regression and Poisson models were used to estimate associations between baseline risk factors of lifestyle, vascular and metabolic health, and inflammation and prevalent or incident brain aging, respectively. In an age-sex adjusted multivariable model, not consuming alcohol (odds ratio(OR) = 1.77, 95% confidence Interval (CI) = 1.18,2.66), higher interleukin-6 levels (OR = 1.30, 95% CI = 1.03,1.64), and depressive symptoms (OR = 2.44, 95% CI = 1.63,3.67) were associated with a higher odds of having brain aging, while higher education had protective effects (OR = 0.55, 95% CI = 0.33,0.94). A history of stroke, arterial stiffness, and obesity were associated with an increased risk of developing brain aging during the five years of follow-up. Lifestyle, vascular, metabolic and inflammatory factors were associated with brain aging in older adults, which adds to the evidence of shared pathways for sensorineural and neurocognitive declines in aging. Targeting these shared central processing etiological factors with interventions may lead to retention of better neurological function, benefiting multiple systems, i.e., hearing, smell, and cognition, ultimately helping older adults retain independence and higher quality of life longer.

Safety and Feasibility of an Early Mobilization Protocol for Patients with Femoral Intra-Aortic Balloon Pumps as Bridge to Heart Transplant.

Intra-aortic balloon pumps (IABPs) can be used to provide hemodynamic support in patients with end-stage heart failure as a bridge to transplantation (BTT). The IABP is commonly inserted via the common femoral artery, which can limit patients' mobility. The Ramsey protocol, developed by a critical care physical therapist, allows patients with femoral IABPs to ambulate with the assistance of a tilt table. The aim of this study was to determine the safety and feasibility of a modified Ramsey protocol for early mobilization of patients with femoral IABPs as BTT. This is a retrospective single-center review of patients with femoral IABPs as BTT using a tilt table protocol from May 2019 to May 2020. Primary outcomes were time to successful ambulation, number of successful ambulation events, and ambulation-associated adverse events, including IABP augmentation, waveform, positioning changes, and vascular complications at the insertion site. Twenty-four patients (mean age 55 ± 16 years) underwent femoral IABP insertion as BTT and were mobilized following our protocol. Nineteen patients (79.2%) successfully ambulated with a median of three sessions (interquartile range, 2-4) per patient. The median time from IABP insertion to ambulation was 3 days (interquartile range, 2-5). Twenty-one patients underwent heart transplantation, of which all 19 who ambulated were successfully bridged to transplantation. Early mobilization in select patients with femoral IABPs can be performed safely and successfully, avoiding the deleterious effects of bed rest that have been historically seen in this patient population.

The Association of Psychological Well-Being With Sensory and Cognitive Function and Neuronal Health in Aging Adults.

OBJECTIVES: Psychological well-being (PWB) may be a potential modifiable risk factor of age-related diseases. We aimed to determine associations of PWB with sensorineural and cognitive function and neuronal health in middle-aged adults. METHODS: This study included 2039 Beaver Dam Offspring Study participants. We assessed PWB, hearing, visual acuity, contrast sensitivity impairment, olfactory impairment, cognition, and retinal (macular ganglion cell inner-plexiform layer, mGCIPL) thickness. Age-sex-education-adjusted multivariable linear, logistic regression, and generalized estimating equation models were used and then further adjusted for health-related confounders. RESULTS: Individuals with higher PWB had better hearing functions, visual acuity, and thicker mGCIPL and reduced odds for hearing, contrast sensitivity and olfactory impairment in age-sex-education-adjusted models. Effects on mGCIPL and visual and olfactory measures decreased with adjustment. Higher PWB was associated with better cognition, better combined sensorineural-cognitive function, and decreased cognitive impairment. DISCUSSION: Psychological well-being was associated with sensorineural-cognitive health indicating a potential of PWB interventions for healthy aging.

Increasing Rates of Prone Positioning in Acute Care Patients with COVID-19.

BACKGROUND: Prone positioning improves mortality in patients intubated with acute respiratory distress syndrome and has been proposed as a treatment for nonintubated patients with COVID-19 outside the ICU. However, there are substantial patient and operational barriers to prone positioning on acute floors. The objective of this project was to increase the frequency of prone positioning among acute care patients with COVID-19. METHODS: The researchers conducted a retrospective analysis of all adult patients admitted to the acute care floors with COVID-19 respiratory failure. A run chart was used to quantify the frequency of prone positioning over time. For the subset of patients assisted by a dedicated physical therapy team, oxygen before and after positioning was compared. The initiative consisted of four separate interventions: (1) nursing, physical therapy, physician, and patient education; (2) optimization of supply management and operations; (3) an acute care prone positioning team; and (4) electronic health record optimization. RESULTS: From March 9, 2020, to August 26, 2020, 176/875 (20.1%) patients were placed in prone position. Among these, 43 (24.4%) were placed in the prone position by the physical therapy team. Only 2/94 (2.1%) eligible patients admitted in the first two weeks of the pandemic were ever documented in prone position. After launching the initiative, weekly frequency peaked at 13/28 (46.4%). Mean oxygen saturation was 91% prior to prone positioning vs. 95.2% after (p < 0.001) in those positioned by physical therapy. CONCLUSION: A multidisciplinary quality improvement initiative increased frequency of prone positioning by proactively addressing barriers in knowledge, equipment, training, and information technology.

Cutaneous Actinomycosis of the Perineum in an Immunocompetent Man.

ABSTRACT: We present a case of primary cutaneous actinomycosis of unclear pathogenesis. A 30-year-old-man with no significant medical or surgical history presented to the emergency department with a 2-week history of a tender perineal mass. The patient denied trauma or perforating injury to the area. Examination of the area revealed an indurated, nonfluctuant, erythematous papulonodule located 2 cm from the anus. The lesion was unresponsive to oral and topical antibiotics and was therefore excised. The excision specimen revealed a dense mixed infiltrate partially filling the reticular dermis and extending into the subcutaneous fat. The infiltrate surrounded grains of basophilic material with an outer rim of eosinophilic radiating Splendore-Hoeppli material. Within the grains, filamentous bacteria were highlighted with Periodic acid-Schiff and Grocott's methenamine silver. The organisms were gram-positive and acid-fast negative. Given the clinical and histopathologic findings, actinomycosis was diagnosed. Two weeks later, the patient reported resolution of symptoms. The patient was lost to follow-up. This case highlights an unusual presentation of actinomycosis and the crucial role histopathology plays in diagnosis.

Factors Affecting Hearing Aid Adoption by Adults With High-Frequency Hearing Loss: The Beaver Dam Offspring Study.

PURPOSE: Hearing loss (HL) is common among middle-age and older adults, but hearing aid adoption is low. The purpose of this study was to measure the 10-year incidence of hearing aid adoption in a sample of primarily middle-age adults with high-frequency HL and identify factors associated with hearing aid adoption. METHOD: This study included 579 adults (ages 34-80 years) with high-frequency pure-tone average > 25 dB HL (3-8 kHz) enrolled in the Beaver Dam Offspring Study. Hearing aid adoption was measured at 5- and 10-year follow-up examinations. Cox discrete-time proportional hazards models were used to evaluate factors associated with hearing aid adoption (presented as hazards ratios [HRs] and 95% confidence intervals [95% CI]). RESULTS: The 10-year cumulative incidence of hearing aid adoption was 14 per 1,000 person years. Factors significantly associated with adoption in a multivariable model were higher education (vs. 16+ years; 0-12: HR: 0.36, 95% CI [0.19, 0.69]; 13-15: HR: 0.52, 95% CI [0.27, 0.98]), worse high-frequency pure-tone average (per +1 dB; HR: 1.04, 95% CI [1.02, 1.06]), self-reported hearing handicap (screening versions of the Hearing Handicap Inventory score > 8; HR: 1.85, 95% CI [1.02, 3.38]), answering yes to "Do friends and relatives think you have a hearing problem?" (HR: 3.18, 95% CI [1.60, 6.33]) and using closed captions (HR: 2.86, 95% CI [1.08, 7.57]). Effects of age and sex were not significant. CONCLUSIONS: Hearing aid adoption rates were low. Hearing sensitivity, socioeconomic status, and measures of the impact of HL on daily life were associated with adoption. Provider awareness of associated factors can contribute to timely and appropriate intervention.

Extracellular matrix protein N-glycosylation mediates immune self-tolerance in Drosophila melanogaster.

In order to respond to infection, hosts must distinguish pathogens from their own tissues. This allows for the precise targeting of immune responses against pathogens and also ensures self-tolerance, the ability of the host to protect self tissues from immune damage. One way to maintain self-tolerance is to evolve a self signal and suppress any immune response directed at tissues that carry this signal. Here, we characterize the Drosophila tuSz1 mutant strain, which mounts an aberrant immune response against its own fat body. We demonstrate that this autoimmunity is the result of two mutations: 1) a mutation in the GCS1 gene that disrupts N-glycosylation of extracellular matrix proteins covering the fat body, and 2) a mutation in the Drosophila Janus Kinase ortholog that causes precocious activation of hemocytes. Our data indicate that N-glycans attached to extracellular matrix proteins serve as a self signal and that activated hemocytes attack tissues lacking this signal. The simplicity of this invertebrate self-recognition system and the ubiquity of its constituent parts suggests it may have functional homologs across animals.

Atraumatic forearm swelling in a patient with poorly controlled asthma.

We present a case of sarcoidosis presenting as unilateral forearm swelling. A 65-year-old male with a long history of asthma presented with unexplained left forearm and hand swelling. Over many years, chest imaging had been devoid of adenopathy or parenchymal findings suspicious for sarcoid, until after the extremity findings emerged. The patient was diagnosed based on subcutaneous, dermal and mediastinal lymph node histopathology. Sarcoid presenting with isolated extremity findings prior to more typical pulmonary manifestations is rare even for cutaneous or soft tissue sarcoid, highlighting the need to maintain a high index of suspicion for sarcoidosis.

Benefit of Musical Training for Speech Perception and Cognition Later in Life.

Purpose The aim of this study was to determine the long-term associations of musical training with speech perception in adverse conditions and cognition in a longitudinal cohort study of middle-age to older adults. Method This study is based on Epidemiology of Hearing Loss Study participants. We asked participants at baseline (1993-1995) about their musical training. Speech perception (word recognition in competing message; Northwestern University Auditory Test Number 6), cognitive function (cognitive test battery), and impairment (self-report or surrogate report of Alzheimer's disease or dementia, and/or a Mini-Mental State Examination score ≤ 24) were assessed up to 5 times over the 20-year follow-up. We included 2,938 Epidemiology of Hearing Loss Study participants who had musical training data and at least one follow-up of speech perception and/or cognitive assessment. We used linear mixed-effects models to determine associations between musicianship and decline in speech perception and cognitive function over time and Cox regression models to evaluate associations of musical training with 20-year cumulative incidence of speech perception and cognitive impairment. Models were adjusted for age, sex, and occupation and repeated with additional adjustment for health-related confounders and education. Results Musicians showed less speech perception decline over time with stronger effects in women (0.16% difference, 95% confidence interval [CI] [0.05, 0.26]). Among men, musicians had, on average, better speech perception than nonmusicians (3.41% difference, 95% CI [0.62, 6.20]) and were less likely to develop a cognitive impairment than nonmusicians (hazard ratio = 0.58, 95% CI [0.37, 0.91]). Conclusions Musicians showed an advantage in speech perception abilities and cognition later in life and less decline over time with different magnitudes of effect sizes in men and women. Associations remained with further adjustment, indicating that some degree of the advantage of musical training is independent of socioeconomic or health differences. If confirmed, these findings could have implications for developing speech perception intervention and prevention strategies. Supplemental Material https://doi.org/10.23641/asha.14825454.

Factors Associated with the Macular Ganglion Cell-Inner Plexiform Layer Thickness in a Cohort of Middle-aged U.S. Adults.

SIGNIFICANCE: The macular ganglion cell-inner plexiform layer (mGCIPL) may serve as a quick and easily obtained measure of generalized neurodegeneration. Investigating factors associated with this thickness could help to understand neurodegenerative processes. PURPOSE: This study aimed to characterize and identify associated factors of the mGCIPL thickness in a Beaver Dam Offspring Study cohort of middle-aged U.S. adults. METHODS: Baseline examinations occurred from 2005 to 2008, with follow-up examinations every 5 years. Included participants had baseline data and measured mGCIPL at 10-year follow-up (N = 1848). The mGCIPL was measured using the Cirrus 5000 HD-OCT Macular Cube Scan. Associations between mean mGCIPL thickness and thin mGCIPL, defined as 1 standard deviation (SD) below the population mean, and baseline risk factors were investigated using generalized estimating equations. RESULTS: Participants (mean [SD] baseline age, 48.9 [9.3] years; 54.4% women) had mean (SD) mGCIPL thicknesses of 78.4 (8.1) µm in the right eye and 78.1 (8.5) µm in the left (correlation coefficient = 0.76). In multivariable models, age (-1.07 µm per 5 years; 95% confidence interval [CI], -1.28 to -0.86 µm), high alcohol consumption (-1.44 µm; 95% CI, -2.72 to -0.16 µm), higher interleukin 6 levels (50% increase in level: -0.23 µm; 95% CI, -0.45 to 0.00 µm), myopia (-2.55 µm; 95% CI, -3.17 to -1.94 µm), and glaucoma (-1.74 µm; 95% CI, -2.77 to -0.70 µm) were associated with thinner mGCIPL. Age (per 5 years: odds ratio [OR], 1.38; 95% CI, 1.24 to 1.53), diabetes (OR, 1.89, 95% CI, 1.09 to 3.27), myopia (OR, 2.11; 95% CI, 1.63 to 2.73), and increasing and long-term high C-reactive protein (ORs, 1.46 [95% CI, 1.01 to 2.11] and 1.74 [95% CI, 1.14 to 2.65], respectively) were associated with increased odds of thin mGCIPL. CONCLUSIONS: Factors associated cross-sectionally with mGCIPL thickness, older age, high alcohol consumption, inflammation, diabetes, myopia, and glaucoma may be important to neural retina structure and health and neuronal health system-wide.

Certified Nurse-Midwives in Rural Kansas Hospitals: A Survey of Senior Hospital Administrators.

INTRODUCTION: Little is known about the nurse-midwifery workforce in rural Kansas hospitals, despite Kansas facing a shortage of primary care physicians providing maternity care rurally. This study investigated the current number of hospitals with certified nurse-midwives (CNMs) with privileges to attend births in Kansas hospitals located in frontier, rural, and densely settled rural counties and anticipated trends in the size of the CNM workforce at hospitals over the next 5 years. METHODS: Electronic surveys were distributed to senior hospital administrators at 94 hospitals in rural Kansas from June to July 2019. The survey included both open and closed-ended questions related to scope of CNM privileges, collaborative agreements, and forecasted trends in the CNM workforce in rural Kansas. RESULTS: Fifty-six hospitals completed the survey. Only one hospital reported having CNM-attended births. Twenty-eight of 37 hospital administrators agreed CNMs should have collaborative agreements with physicians. Most respondents did not anticipate the number of CNMs with privileges to increase at their hospitals over the next 5 years. DISCUSSION: Future research should focus on understanding the factors limiting CNM expansion in rural Kansas, because CNMs represent an untapped, additional maternity care workforce for rural Kansas.

Varied Factors were Associated with Different Types of Self-Care in Heart Failure.

Poor self-care is prevalent in patients with heart failure and adversely affects heart failure symptoms, hospitalization, and mortality. Adherence rates to different types of self-care vary in patients with heart failure. The purpose of this study was to examine factors associated with medication adherence, dietary sodium adherence, and symptom management in patients with heart failure. Data were collected using questionnaires, Medication Electronic Monitoring System, and 24-hour urine sodium output (N = 94). In logistic regression analysis, social support, education level, and race were associated with medication adherence (p = .002). Gender, race, perceived control, and depressive symptoms were associated with dietary sodium adherence (p = .030). Gender, education level, and depressive symptoms were associated with symptom management (p = .006). Different factors were associated with each type of self-care. Thus, clinicians need to manage each type of self-care by considering factors associated with it.

Generational Differences in the 10-year Incidence of Impaired Contrast Sensitivity.

PURPOSE: To determine if incidence of contrast sensitivity (CS) impairment differs by generation and identify factors to explain these differences. METHODS: The Beaver Dam Eye Study (BDES) and Beaver Dam Offspring Study (BOSS) are cohort studies of aging adults in Beaver Dam, Wisconsin. Baseline examinations occurred from 1993 to 1995 (BDES) and 2005-2008 (BOSS). Follow-up examinations occurred in five-year intervals. CS testing was conducted with Pelli-Robson letter sensitivity charts; Incident impairment was a log CS score <1.55 in either eye at follow-up. Associations of incidence with generation were investigated using estimated hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: Participants (N = 3185) had a mean age of 51.9 years at baseline (standard deviation = 9.9) and 51.9% were female. Ten-year cumulative incidence of CS impairment was 40.1%, was higher among women (41.7%) than men (38.8%), and increased by age group. The risk of incident CS impairment decreased by 39% per generation. In multivariable models, the Baby Boom Generation (HR = 0.42, 95%CI = 0.31, 0.58) and Generation X (HR = 0.56, 95%CI = 0.34, 0.91) had a significantly decreased risk of CS impairment compared to the Greatest Generation. Results were similar in sensitivity analyses excluding those with cataract, age-related macular degeneration, or visual acuity impairment. CONCLUSION: The risk of incident CS impairment decreased by birth cohort, with the greatest reduction in the Baby Boom Generation. The difference in risk suggests that there are unknown modifiable risk factors that may help to further explain the etiology of CS impairment and provide potential pathways for prevention in the future.

Survival outcomes of acute normovolemic hemodilution in patients undergoing primary debulking surgery for advanced ovarian cancer: A Memorial Sloan Kettering Cancer Center Team Ovary study.

OBJECTIVE: To describe oncologic outcomes after using acute normovolemic hemodilution (ANH) to reduce requirement for allogenic red blood cell transfusions (ABT) in patients undergoing primary debulking surgery (PDS) for advanced ovarian cancer. METHODS: We performed a post-hoc analysis of a recent prospective trial investigating the safety and feasibility of ANH during PDS for advanced ovarian cancer. We report long-term survival outcomes. We compared demographics, clinicopathological characteristics, survival outcomes in this cohort of Stage IIIB-IVB high-grade serous ovarian cancer patients undergoing ANH (ANH group), with a retrospective cohort of all other patients (standard group) undergoing PDS during the same time period (01/2012-04/2017). Standard statistical tests were used. RESULTS: There were no demographic or clinicopathological differences between ANH (n = 33) and standard groups (n = 360), except for higher median age at diagnosis (57 vs. 62 years, respectively; p = 0.044) and shorter operative time (357 vs. 446 min, respectively; p < 0.001) in the standard group. Cytoreductive outcomes (ANH vs. standard): 0 mm, 69.7 vs. 63.9%; gross residual disease (RD) ≤1 cm, 21.2 vs. 26.9%; >1 cm, 9.1 vs. 9.2% (p = 0.78). RD after PDS was the only independent factor associated with worse progression-free survival (PFS) on multivariable analysis (p < 0.001). Patients with BRCA mutations trended towards improved PFS (p = 0.057). Significant factors for overall survival (OS) on multivariable analysis: preoperative CA125 (p = 0.004), ascites (p = 0.018), RD after PDS (p = 0.04), BRCA mutation status (p < 0.001). After adjustment for potential confounders, ANH was not independently associated with PFS or OS [PFS: HR 0.928 (0.618-1.395); p = 0.721; OS: HR 0.588 (95%CI: 0.317-1.092); p = 0.093]. CONCLUSIONS: ANH is an innovative approach in intraoperative management. It was previously proven to decrease need for ABT while maintaining the ability to achieve complete gross resection and associated benefits.

Predicting hearing aid use in adults: the Beaver Dam Offspring Study.

OBJECTIVE: The purpose of this study was to (i) develop a model that predicts hearing aid (HA) use and (ii) determine if model fit is improved by adding factors not typically collected in audiological evaluations. DESIGN: Two models were created and evaluated. The "clinical" model used factors typically collected during audiologic clinical evaluations. The "expanded" model considered additional clinical, health and lifestyle factors to determine if the model fit could be improved (compared to clinical model). Models were created with least absolute shrinkage and selection operator (LASSO) logistic regression with 10-fold cross validation. Predictive ability was evaluated via receiver operating characteristic curves and concordance statistics (c-statistics). STUDY SAMPLE: This study included 275 participants from the Beaver Dam Offspring Study, a prospective longitudinal cohort study of aging, with a treatable level of hearing loss and no HA use at baseline. RESULTS: The clinical and expanded models report predictors important for HA use. The c-statistics of the clinical (0.80) and expanded (0.79) models were not significantly different (p = 0.41). CONCLUSIONS: Similar predictive abilities of models suggest audiological evaluations perform well in predicting HA use.
