Introduction: Constraints on surgical resident training (work-hour mandates, shorter training programs, etc.) and availability of expert surgical educators may limit the acquisition of prosthetic surgical skills. As a result, training courses are being conducted to augment the prosthetic surgery learning experience. Aim: To evaluate the impact of a hands-on cadaver-based teaching program on resident procedural knowledge and procedural confidence with placement of a penile prosthesis. Main Outcome Measure: Changes in procedural knowledge and self-confidence following a focused training program on penile prosthetics. Methods: As part of the 2017 Society of Urologic Prosthetic Surgeons and the Sexual Medicine Society of North America Annual Meeting, 31 urology residents participated in a simulation lab in prosthetic urology. The lab included didactic lectures and a hands-on cadaveric laboratory. Participants completed surveys before and after the course. Wilcoxon Signed Rank tests for matched pairs were used to compare respondents’ pre- and postcourse knowledge (% questions answered correctly) and confidence ratings. Prior implant experience was assessed. Results: 31 residents participated in this study. The majority of the participants were 4th- (41.9%) and 5th-year residents (38.7%). Participants showed a significant improvement in procedural knowledge test scores (68.8±13.4 vs 74.2 ± 13.0, P < .05) and self-reported increased median surgical confidence levels (4 vs 3, P value < .001) after completion of the cadaveric course. Subgroup analysis demonstrated that residents with prosthetic surgery experience of

Modern penile implants, introduced to the market almost four decades ago, have provided a predictable and reliable treatment of erectile dysfunction (ED) despite the development of less-invasive therapies. Infection associated with the placement of these devices does occur, and with prophylactic measures and protocols the incidence has decreased fortunately. In the presence of an infection the implant and all foreign material should be removed. A salvage procedure, during which the wound is thoroughly washed with antiseptic solutions after device removal and placement of a new implant during the same procedure, has a high success rate and is becoming a popular approach. The alternative, device removal with return at a later date for placing a new implant, entails a more difficult corporal dilation, and the resulting erection is noticeably shorter. Patient and partner satisfaction with a penile implant is the highest among all of the treatments for ED.

Objectives: This study identifies differences in unmet mobility needs among older adults living in rural versus urban areas., Methods: We used data from Round 9 of the National Health and Aging Trends Study (NHATS), limiting our analyses to respondents who had not moved since baseline (average housing tenure of 27 years; n = 3343). We conducted bivariate and multivariate analyses to detect rural/urban differences in unmet mobility needs, adjusting for socio-demographics, health status, and housing characteristics., Results: Rural residence was associated with higher odds of any unmet mobility need s for older adults aging in place (adjusted odds ratio: 1.64, 95% confidence interval: 1.10-2.44, p < .05). The relationship between rurality and unmet needs for help with mobility limitations remained significant in fully adjusted models., Discussion: Rural older adults aging in place have greater unmet need s for help with mobility limitations. This study highlights several important gaps in supporting rural older adults aging in place.

The Rigicon ContiClassic® is a new sphincteric device designed to treat male stress urinary incontinence. This study evaluates the surgical outcomes and safety profile of the first 116 patients who received the implant between September 2021 and April 2022. Data were collected from patient information forms completed at the time of the implant and submitted by implanting surgeons, nursing staff in the Operating Room or company representatives present during the surgery. The study analyzed patient demographics, surgical details, and etiology of incontinence. The mean age of patients was 68.3 years +/- 9.65 yrs. Minimum age was 23 and maximum age was 83. The most common reason for implantation was urinary incontinence (58.6%) after radical prostatectomy. The results showed a revision rate of 6.90%, with three cases of fluid loss, four cases of iatrogenic mistaken sizing, and one case of patient dissatisfaction. There were no reported infections. Kaplan-Meier calculation showed survival rate of 93.2% at 12 months. This study shows the early safety outcomes for the Rigicon ContiClassic® sphincter device to be comparable to others presently on the market., (© 2023.

Background: Monitoring COVID-19 infection risk in the general population is a public health priority. Few studies have measured seropositivity using representative, probability samples. The present study measured seropositivity in a representative population of Minnesota residents prior to vaccines and assess the characteristics, behaviors, and beliefs of the population at the outset of the pandemic and their association with subsequent infection., Methods: Participants in the Minnesota COVID-19 Antibody Study (MCAS) were recruited from residents of Minnesota who participated in the COVID-19 Household Impact Survey (CIS), a population-based survey that collected data on physical health, mental health, and economic security information between April 20 and June 8 of 2020. This was followed by collection of antibody test results between December 29, 2020 and February 26, 2021. Demographic, behavioral, and attitudinal exposures were assessed for association with the outcome of interest, SARS-CoV-2 seroprevalence, using univariate and multivariate logistic regression., Results: Of the 907 potential participants from the CIS, 585 respondents then consented to participate in the antibody testing (64.4% consent rate). Of these, results from 537 test kits were included in the final analytic sample, and 51 participants (9.5%) were seropositive. The overall weighted seroprevalence was calculated to be 11.81% (95% CI, 7.30%-16.32%) at of the time of test collection. In adjusted multivariate logistic regression models, significant associations between seroprevalence and the following were observed; being from 23-64 and 65+ age groups were both associated with higher odds of COVID-19 seropositivity compared to the 18-22 age group (17.8 [1.2-260.1] and 24.7 [1.5-404.4] respectively). When compared to a less than $30k annual income reference group, all higher income groups had significantly lower odds of seropositivity. Reporting practicing a number of 10 (median reported value in sample) or more of 19 potential COVID-19 mitigation factors (e.g. handwashing and mask wearing) was associated with lower odds of seropositivity (0.4 [0.1-0.99]) Finally, the presence of at least one household member in the age range of 6 to 17 years old was associated with higher odds of seropositivity (8.3 [1.2-57.0])., Conclusions: The adjusted odds ratio of SARS-CoV-2 seroprevalence was significantly positively associated with increasing age and having household member(s) in the 6-17 year age group, while increasing income levels and a mitigation score at or above the median were shown to be significantly protective factors., Competing Interests: No competing interests., (Copyright: © 2023 Abhold et al.

The use of semirigid rod penile prosthesis for the management of erectile dysfunction was first described over 85 years ago. Since then, there have been numerous design advancements leading to improved overall durability, concealability, rigidity, and natural feel. However, the inflatable penile prosthesis (IPP) still has a higher patient satisfaction rate and is currently the most commonly inserted prostheses in the United States. There are still certain situations and conditions where the simplicity of a rod may be preferred over an IPP. A pair of semirigid rods has been shown to have less risk of malfunction and need for revision surgery. In addition, patients with poor manual dexterity, those undergoing a salvage for infection prosthesis and those with a prolonged (> 48 h) priapic episode may be better served with a rod than an IPP. Finally, in patients compromised by infection or priapism, the rods can later successfully be exchanged for an IPP with potentially longer, wider cylinders with resultant greater patient satisfaction., (© 2020.

Objectives: Community-living older Medicare and Medicaid enrollees ("dual-enrollees") have high care needs and commonly receive paid and unpaid long-term services and supports (LTSS) to help with routine activities. Little is known about whether receiving paid help or individuals' state and neighborhood environmental context ("LTSS environment") relates to dual-enrollees' care experiences., Methods: We examine a sample of n = 979 community-dwelling dual-enrollees with disabilities from 2011 to 2015 National Health and Aging Trends Study, linked to measures of neighborhood disadvantage and state Medicaid home and community-based services (HCBS) generosity. Logistic regression models stratified by dementia status assess associations between paid help and: (a) adverse consequences due to unmet care needs, and (b) participation restrictions in valued activities, among dual-enrollees with and without dementia, adjusting for individual and LTSS environmental characteristics., Results: Use of paid help was greater for those with (versus without) dementia (46.9% vs. 37.8%). Neighborhood disadvantage was associated with greater use of paid help among dual-enrollees living with dementia. High state Medicaid HCBS generosity was associated with the use of paid help, regardless of dementia status. Dual-enrollees with dementia receiving paid help had higher odds of experiencing adverse consequences due to unmet need (adjusted odds ratio = 2.05; 95% confidence interval 1.16-3.61; p = .02)-no significant associations were observed for participation restrictions. Use of paid help and LTSS environment were not significantly associated with care experiences for dual-enrollees without dementia., Discussion: Findings highlight the complexities of caring for dual-enrollees, particularly those with dementia, and emphasize the need to strengthen the delivery of paid care with considerations for the LTSS environment., (© The Author(s) 2022.

In a special miniseries highlighting the different surgical techniques to the inflatable penile prosthesis (IPP), Wilson's Workshop seeks to bring forth skill considerations for the modern implanter. Each work is authored by a highly regarded surgeon who has truly honed the art of their respective approach. Today, most implanters are comfortable with either the penoscrotal or suprapubic incision. The following work directs the spotlight onto a much newer and less known technique, IPP implant via the subcoronal incision. SHP leads the Urology Center of Excellence in Seoul, South Korea, and has implanted more than 700 IPPs using the subcoronal approach since 2015. Here, he will share the clinical pearls of this novel incision gathered through trial and error over many repetitions. We are hopeful that this work will peak the interest of inquisitive minds and help disseminate improved implant techniques., (© 2020.

This workshop completes the trilogy of nuances of the various incisions used to place an inflatable penile prosthesis (IPP). Infrapubic placement was the original technique employed 50 years ago for the very first IPP surgeries. The historical perspective of the development of implantation incisions and the original Scott prosthesis highlighted in this work should be fascinating to today's younger prosthetic urologists. The developing surgeon should also find some surprising maneuvers considered important technique nuances from the highest volume infrapubic implanter in the world. Among the wonders of the infrapubic approach covered are: The surgery is conducted without the aid of an in-dwelling Foley catheter or post-operative inflation. Hydrodistension of the corpora substitutes for corporal dilatation. The "chicken choke" protects the urethra from damage. Closed suction drainage is employed despite minimal scrotal dissection. Motivated patients may use their new device as early as 14 days after implantation., (© 2020. The Author(s).)

The inflatable penile prosthesis was first implanted with a large vertical suprapubic incision. Nowadays, three surgical approaches are utilized: penoscrotal, infrapubic, and subcoronal. Globally the penoscrotal approach is used most often. Our first author describes nuances of the high transverse scrotal incision technique gained over 48 years of experience. Many of these methods will interest the reader because they are divergent from the common practice of implanters across the world. These distinctions are designed to diminish the risk of infection, speed up the surgery, and improve outcomes for both the patient and his surgeon., (© 2020.

Background and Purpose: The purpose of this study was to determine the role of Na V 1.7 in action potential conduction in C-fibres in the bronchial branches of the human vagus nerve., Experimental Approach: Bronchial branches of the vagus nerve were dissected from human donor tissue. The C-wave of the electrically evoked compound action potential was quantified in the absence and presence of increasing concentrations of the selective Na V 1.7 blocking drugs, PF-05089771 and ST-2262, as well as the Na V 1.1, 1.2, and 1.3 blocking drug ICA121-431. The efficacy and potency of these inhibitors were compared to the standard Na V 1 blocker, tetrodotoxin. We then compared the relative potencies of the Na V 1 blockers in inhibiting the C-wave of the compound action potential, with their ability to inhibit parasympathetic cholinergic contraction of human isolated bronchi, a response previously shown to be strictly dependent on Na V 1.7 channels., Key Results: The selective Na V 1.7 blockers inhibited the C-wave of the compound action potential with potencies similar to that observed in the Na V 1.7 bronchial contractions assay. Using rt-PCR, we noted that Na V 1.7 mRNA was strongly expressed and transported down the vagus nerve bundles., Conclusions and Implications: Na V 1.7 blockers can prevent action potential conduction in the majority of vagal C-fibres arising from human bronchi. Blockers of Na V 1.7 channels may therefore have value in inhibiting the responses to excessive airway C-fibre activation in inflammatory airway disease, responses that include coughing as well as reflex bronchoconstriction and secretions., (© 2021 The British Pharmacological Society.)

Objectives: To examine social and physical environmental fall-risk factors in a nationally representative sample of community-living older adults overall and by racial group. Methods: We used data from the 2015 and 2016 rounds of the National Health and Aging Trends Study ( n = 5581) linked to census tract measures from the American Community Survey. Recurrent falls are defined as 2+ self-reported falls over 12 months. Results: Older adults with recurrent falls were more likely to have lower education, lower income, financial hardship, live in homes with disorder and disrepair and in neighborhoods without sidewalks, with high social deprivation, and in nonmetropolitan counties. Home disrepair, lack of sidewalks, and residence in a nonmetropolitan county were important fall-risk factors among White older adults only. Financial hardship was an important risk factor among Black older adults. Discussion: Environmental factors are associated with recurrent falls among older Americans and should be incorporated into fall-risk profiles and prevention efforts.

Background/objectives: Hospitalization is common among older adults with disability, many of whom receive help from a caregiver and have dementia. Our objective was to evaluate the association between caregiver factors and risk of hospitalization and whether associations differ by dementia status., Design: Longitudinal observational study., Setting: The 1999 and 2004 National Long-Term Care Survey and the 2011 and 2015 National Health and Aging Trends Study, linked caregiver surveys, and Medicare claims., Participants: A total of 2,589 community-living Medicare fee-for-service beneficiaries, aged 65 years or older (mean age = 79 years; 63% women; 31% with dementia), with self-care or mobility disability and their primary family or unpaid caregiver., Measurements: Self-reported characteristics of older adults and their caregivers were assessed from older adult and caregiver survey interviews. Older adult hospitalization over the subsequent 12 months was identified in Medicare claims. Multivariable Cox proportional hazards models adjusted for older adult characteristics and were stratified by dementia status., Results: In this nationally representative cohort, 38% of older adults with disabilities were hospitalized over 12 months following interview. Increased hospitalization risk was associated with having a primary caregiver who helped with healthcare tasks (adjusted hazard ratio (aHR) = 1.22; 95% confidence interval (CI) = 1.05-1.40), reported physical strain (aHR = 1.21; 95% CI = 1.04-1.42), and provided more than 40 hours of care weekly (aHR = 1.26; 95% CI = 1.04-1.54 vs ≤20 hours). Having a caregiver who had helped for 4 years or longer (vs <1 year) was associated with 38% lower risk of hospitalization (aHR = 0.62; 95% CI = 0.49-0.79). Older adults with and without dementia had similar rates of hospitalization (39.5% vs 37.3%; P = .4), and caregiving factors were similarly associated with hospitalization regardless of older adults' dementia status., Conclusion: Select caregiving characteristics are associated with hospitalization risk among older adults with disability. Hospitalization risk reduction strategies may benefit from understanding and addressing caregiving circumstances., (© 2020 The American Geriatrics Society.)

Objectives: To assess two models for the prediction of health utilization and functions using standardized in-person assessments of frailty and administrative claims-based geriatric risk measures among Medicare fee-for-service beneficiaries aged 65 years and above. Methods: Outcomes of hospitalizations, death, and functional help were investigated for participants in the 2011 National Health and Aging Trends Study. For each outcome, multivariable logistic regression model was used to investigate claims-based geriatric risk and survey-based frailty. Results: Both claims-based and survey-based models showed moderate discrimination. The c-statistic of the standardized frailty models ranged from 0.67 (for any hospitalization) to 0.84 (for any IADL [instrumental activities of daily living] help). Models using administrative data ranged from 0.71 (for any hospitalization) to 0.81 (for any IADL help). Discussion: Models based on existing administrative data appear to be as discriminate as survey-based models. Health care providers and insurance plans can effectively apply existing data resources to help identify high-risk individuals for potential care management interventions.

Background: Cellulite is a common physiological condition of dermis, epidermis, and subcutaneous tissues experienced by 85 to 98% of the post-pubertal females in developed countries. Infrared (IR) thermography combined with artificial intelligence (AI)-based automated image processing can detect both early and advanced cellulite stages and open up the possibility of reliable diagnosis. Although the cellulite lesions may have various levels of severity, the quality of life of every woman, both in the physical and emotional sphere, is always an individual concern and therefore requires patient-oriented approach., Objectives: The purpose of this work was to elaborate an objective, fast, and cost-effective method for automatic identification of different stages of cellulite based on IR imaging that may be used for prescreening and personalization of the therapy., Materials and Methods: In this study, we use custom-developed image preprocessing algorithms to automatically select cellulite regions and combine a total of 9 feature extraction methods with 9 different classification algorithms to determine the efficacy of cellulite stage recognition based on thermographic images taken from 212 female volunteers aged between 19 and 22., Results: A combination of histogram of oriented gradients (HOG) and artificial neural network (ANN) enables determination of all stages of cellulite with an average accuracy higher than 80%. For primary stages of cellulite, the average accuracy achieved was more than 90%., Conclusions: The implementation of computer-aided, automatic identification of cellulite severity using infrared imaging is feasible for reliable diagnosis. Such a combination can be used for early diagnosis, as well as monitoring of cellulite progress or therapeutic outcomes in an objective way. IR thermography coupled to AI sets the vision towards their use as an effective tool for complex assessment of cellulite pathogenesis and stratification, which are critical in the implementation of IR thermographic imaging in predictive, preventive, and personalized medicine (PPPM)., Competing Interests: Conflict of interestThe authors declare that they have no conflict of interest., (© The Author(s) 2020.)

Background and Objectives: Spending in the Medicaid program is a significant concern to both state and federal policy makers. Medicaid spending is driven by program enrollment and services use. Older adults with high health care needs incur a disproportionate proportion of program spending. This analysis identifies factors that place older Medicare beneficiaries at increased risk for entering into Medicaid., Research Design and Methods: We use multinomial logistic regression and the 2011-2017 National Health and Aging Trends Study (NHATS) to examine the risks among older Medicare beneficiaries for entering into Medicaid over a 6-year follow-up period. We examine both time-invariant and time-varying factors to measure the impact of social and health and functioning changes at older ages., Results: The risk of entry into Medicaid was higher for older adults who relocated to a nursing home (relative risk ratio [RRR]: 7.75; 95% confidence interval [CI]: 5.33-11.26) or other residential care setting (RRR: 1.36; 95% CI: 0.96-1.92) compared to those who remained in traditional community settings. Older adults who reported skipping a meal in the last month because there was not enough money to buy food were 2.4 times (95% CI: 1.10-5.21) more likely to enter Medicaid than those who did not. Similarly, older adults who reported not having enough money to pay household utility bills in the last year were 1.89 times (95% CI: 1.08-3.30) more likely to enter Medicaid., Discussion and Implications: Study findings suggest that trouble paying for basic needs increases the risk of entry into Medicaid. Further research is required to examine whether addressing these needs through improved access to social services that enable older adults to live safely in their home may delay or mitigate entry into Medicaid., (© The Author(s) 2019.

Background: Identifying factors that affect variation in health care spending among older adults with disability may reveal opportunities to better address their care needs while offsetting excess spending., Objective: To quantify differences in total Medicare spending among older adults with disability by whether they experience negative consequences due to inadequate support with household activities, mobility, or self-care., Design: Observational study of in-person interviews and linked Medicare claims., Setting: United States, 2015., Participants: 3716 community-living older adults who participated in the 2015 NHATS (National Health and Aging Trends Study) and survived for 12 months., Measurements: Total Medicare spending by spending quartile in multivariable regression models that adjusted for individual characteristics., Results: Negative consequences were experienced by 18.3% of participants with disability in household activities, 25.6% with mobility disability, and 20.0% with self-care disability. Median Medicare spending was higher for those who experienced negative consequences due to household ($4866 vs. $4095), mobility ($7266 vs. $4115), and self-care ($10 935 vs. $4436) disability versus those who did not. In regression-adjusted analyses, median spending did not differ appreciably for participants who experienced negative consequences in household activities ($338 [95% CI, -$768 to $1444]), but was higher for those with mobility ($2309 [CI, $208 to $4409]) and self-care ($3187 [CI, $432 to $5942]) disability. In the bottom-spending quartile, differences were observed for self-care only ($1460 [CI, $358 to $2561]). No differences were observed in the top quartile., Limitation: This observational study could not establish causality., Conclusion: Inadequate support for mobility and self-care is associated with higher Medicare spending, especially in the middle and lower ends of the spending distribution. Better support for the care needs of older adults with disability could offset some Medicare spending., Primary Funding Source: The Commonwealth Fund.

Introduction: The Mulcahy salvage fundamentally altered the management of penile prosthesis infections (PPI). Central to this procedure is a sequence of antiseptic irrigations that aims to remove and eradicate pathogenic microflora from the infected field, thus preparing for immediate reimplantation. The antiseptic solutions and their respective concentrations, however, have never been evaluated for efficacy., Aim: This review critically examines 3 commonly used antiseptic irrigation solutions (povidone-iodine [PVI], hydrogen peroxide [H 2 O 2 ], and chlorhexidine gluconate [CHG]) in terms of their antimicrobial activity, cytotoxicity, and clinical use., Methods: A PubMed literature review was performed on articles published between 2003 and 2018. Both preclinical as well as clinical studies from various surgical disciplines were included in this review., Main Outcome Measure: The original salvage protocol selected for irrigation solutions at concentrations that are likely detrimental to native tissue., Results: All 3 agents demonstrate in vitro cytotoxic effects at subclinical concentrations, but H 2 O 2 is associated with the most significant deleterious properties. It does not seem to broaden antimicrobial coverage beyond what is covered by PVI. Dilute PVI (0.35-3.5% with exposure time of at least 3 minutes) possesses the most robust clinical evidence as an intraoperative adjunct, reducing the incidence of postoperative infectious complications. chlorhexidine gluconate is a promising new agent but lacks clinical data., Clinical Implication: Improvements in the salvage protocol are warranted based on current evidence. Careful selection of lavage solution and usage of the lowest necessary concentration will help achieve desired antimicrobial activity while avoiding native tissue cytotoxicity. Strength and limitation: The study is limited by its retrospective nature, and the heterogeneity of literature reviewed precluded a formal meta-analysis. Furthermore, future studies will need to address the roles of normal saline and antibiotic irrigations as intraoperative adjuncts for infection prevention., Conclusion: Diluted PVI (0.35-3.5% for 3 minutes) may be beneficial in the prevention of PPI. Evidence supports its use both in the setting of primary implantation as well as salvage of infected hardware. An improved, evidence-based protocol may increase positive outcomes of urologic prosthetic surgery. Pan S, Rodriguez D, Thirumavalavan N, et al.

Mobile phones have become an indispensable utility to modern society, with international use increasing dramatically each year. The GSM signal operates at 900 MHz, 1800 MHz and 2250 MHz, may potentially cause harm to human tissue. Yet there is no in silico model to aid design these devices to protect from causing potential thermal effect. Here we present a model of sources of heating in a mobile phone device with experimental verification during the phone call. We have developed this mobile phone thermal model using first principles on COMSOL® Multiphysics modelling platform to simulate heating effect in human auricle region due to mobile phone use. In particular, our model considered both radiative and non-radiative heating from components such as the lithium ion battery, CPU circuitry and the antenna. The model showed the distribution and effect of the heating effect due to mobile phone use and considered impact of battery discharge rate, battery capacity, battery cathode material, biological tissue distance, antenna radio-wave frequency and intensity. Furthermore, the lithium ion battery heating was validated during experiments using temperature sensors with an excellent agreement between simulated and experimental data (<1% variation). Mobile phone heating during a typical call has also been simulated and compared with experimental infrared thermographic imaging. Importantly, we found that 1800 MHz frequency of data transmission showed the highest temperature increase in the fat/water phantom used in this simulation. We also successfully compared heating distribution in human auricle region during mobile phone use with clinical thermographic images with reasonable qualitative and quantitative agreements. In summary, our model provides a foundation to conceive thermal and other physical effects caused by mobile phone use and allow for the understanding of potential negative health effects thus supporting and promoting personalized and preventive medicine using thermography., (Copyright © 2018 Elsevier Ltd.

Issue: Older adults' needs have evolved and are no longer met by the Medicare program. With the recent passage of the Bipartisan Budget Act of 2018 (BBA), Medicare Advantage (MA) plans can now provide beneficiaries with nonmedical benefits, such as long-term services and supports (LTSS), which Medicare does not cover., Goal: To examine the use of LTSS among Medicare beneficiaries age 65 and older living in the community and explore differences by age, income, and other variables., Methods: Descriptive analyses of the National Health and Aging Trends Study (NHATS), 2015., Findings and Conclusions: Two-thirds of older adults living in the community use some degree of LTSS. Reliance on assistive devices and environmental modifications is high; however many adults, particularly dual-eligible beneficiaries, experience adverse consequences of not receiving care. Although the recent policy change allowing MA plans to offer LTSS benefits is an important step toward meeting the medical and nonmedical needs of Medicare beneficiaries, only the one-third of Medicare beneficiaries enrolled in MA plans stand to benefit. Accountable care organizations operating in traditional Medicare also should have the increased flexibility to provide nonmedical services.

Issue: In addition to medical care, individuals with functional or cognitive impairment often require long-term services and supports (LTSS), which Medicare does not cover. Little is known about the additional out-of-pocket expenses that individuals and their families incur to meet these needs., Goal: To analyze medical and LTSS spending among older Medicare beneficiaries, particularly the costs of assistive devices and personal care and the ways those costs are met., Methods: Descriptive analyses of the National Health and Aging Trends Study (NHATS), 2015., Key Findings and Conclusions: Beneficiaries with high LTSS needs have higher Medicare and out-of-pocket spending than those without such needs and are more likely to report that medical care makes up part of their credit card debt. Those with high LTSS needs are also more likely to report trouble paying for food, rent, utilities, medical care, and prescription drugs. Many older Medicare beneficiaries using LTSS are vulnerable to incurring substantial costs. Without an affordable, sustainable financing solution, Medicare beneficiaries with LTSS needs will continue to be at greater risk of delaying necessary care, being placed in a nursing home prematurely, and having to "spend down" into the Medicaid program.

Background: Older adults with disability are frequent users of the emergency department (ED) and often rely on family caregiver support. We identify whether and which caregiver characteristics are associated with older adults' ED use. Methods: We use Cox proportional hazards regression to model the likelihood of all-cause ED use (defined as 1 or more visits within 12 months of survey) as a function of caregiver characteristics after adjusting for older adult sociodemographic and health characteristics. We draw from linked older adult and caregiver surveys and administrative claims, creating a sample of 2521 community-living older adults with mobility/self-care disability receiving care from a family or unpaid caregiver. Results: About half (52.5%) of older adults receiving mobility or self-care help incurred 1 or more ED visits within 12 months of interview. Adjusting for year of data collection, sociodemographic characteristics, and health status, these older adults were at greater risk of all-cause ED use if their primary caregiver provided greater than 40 hours of care per week (hazard ratio [HR] 1.22, 95% CI 1.04-1.43; P = .02), helped with health care tasks (HR 1.26; 95% CI 1.08-1.46; P < .01), or experienced physical strain (HR 1.18; 95% CI 1.03-1.36; P = .02). Conclusion: Caregiver strain, helping with health care tasks, and greater hours of help per week are associated with heightened risk of ED use among older adults receiving mobility or self-care help. Study findings suggest the potential benefit of caregiver assessment and support.

Purpose of Study: To assess trends in family caregiving between 1999 and 2015., Design and Methods: We construct nationally representative profiles of community-dwelling older adults receiving help with self-care or indoor mobility and their "primary" family or unpaid caregiver using the 1999 and 2004 National Long Term Care Survey, 2011 and 2015 National Health and Aging Trends Study, and linked caregiver surveys. Trends are examined., Results: Older adults receiving help were incrementally younger, more racially diverse, and better educated in 2015. Primary caregivers overwhelmingly continued to be spouses and adult children. Arrangements were increasingly 4 years or longer in duration (shifting from 44.8% in 1999 to 60.5% by 2015). On average, primary caregivers provided about or in excess of 30 hr per week at all four time points. Spouses provided fewer hours of care, were twice as likely to work, and half as likely to report substantial emotional, physical, and financial difficulty due to caregiving in 2015 than 1999. Adult children provided comparable hours of care to a more impaired population; a similar proportion reported substantial caregiving-related difficulty at each time. Use of respite care nearly doubled from 8.5% in 1999 to 15.7% in 2015. Dementia caregivers were less likely to report substantial physical and financial difficulty and more likely to use respite care in 2015 than 1999., Implications: Family caregivers' circumstances generally improved during the 16-year period. Results diverge from prevailing concerns regarding the state of family caregiving and demonstrate the importance of longitudinally monitoring trends in late-life family caregiving.

Objectives: To comprehensively examine factors associated with long-term nursing home (NH) entry from 6 domains of older adult and family caregiver risk from nationally representative surveys and develop a prognostic model and a simple scoring system for use in risk stratification., Design: Retrospective observational study., Setting: National Long-Term Care Surveys 1999 and 2004 and National Health and Aging Trends Study 2011 and linked caregiver surveys., Participants: Community-living older adults receiving help with self-care disability and their primary family or unpaid caregiver (N=2,676)., Measurements: Prediction of long-term NH entry (>100 days or ending in death) by 24 months follow up, ascertained from Minimum Data Set assessments and dates of death from Medicare enrollment files. Risk factors were measured from survey responses., Results: In total, 16.1% of older adults entered a NH. Our final model and risk scoring system includes 7 independent risk factors: older adult age (1 point/5 years), living alone (5 points), dementia (3 points), 3 or more of 6 self-care activities (2 points), caregiver age (45-64: 1 point, 65-74: 2 points, ≥75: 4 points), caregiver help with money management (2 points), and caregiver report of moderate (2 points) or high (4 points) strain. Using this model, participants were assigned to risk quintiles. Long-term NH entry was 7.0% in the lowest quintile (0-6 points), 20.4% in the middle 3 quintiles (7-14 points), and 30.9% in the highest quintile (15-22 points). The model was well calibrated and demonstrated moderate discrimination (c-statistic=0.670 in the original data, c-statistic=0.647 in bootstrapped samples, c-statistic=0.652 using the point-scoring system)., Conclusion: We developed a prognostic model and simple scoring system that may be used to stratify risk of long-term NH entry of community-living older adults. Our model may be useful for population health and policy applications., (© 2018, Copyright the Authors Journal compilation © 2018, The American Geriatrics Society.)

Issue: Older adults who reside in communities, as opposed to nursing homes or other residential institutions, are largely dependent on family and unpaid caregivers for assistance with daily activities, like preparing meals or laundry, and self-care tasks like bathing or dressing. For low-income older adults, assistance with such activities, also known as long-term services and supports (LTSS), can also come from Medicaid. These sources of support will be increasingly inadequate as the population ages., Goals: To examine the extent of paid and unpaid personal care assistance used by community-residing people who require LTSS; and to analyze how this differs by demographics and the economic status of Medicare beneficiaries., Methods: Descriptive analyses of the National Health and Aging Trends Study (NHATS), 2015., Findings and Conclusions: Medicare beneficiaries needing LTSS rely predominantly on unpaid care. Hours of unpaid care are not substantially lower when paid care is also received. Findings suggest that public financing of LTSS would not replace but rather supplement the contribution of family and unpaid caregivers to support individuals living independently in the community.

Objective: A robust release of endothelin-1 with subsequent endothelin-A subtype receptor activation occurs in patients after cardiac surgery requiring cardiopulmonary bypass. Increased endothelin-A subtype receptor activation has been identified in patients with poor left ventricular function (reduced ejection fraction). Accordingly, this study tested the hypothesis that a selective endothelin-A subtype receptor antagonist administered perioperatively would favorably affect post-cardiopulmonary bypass hemodynamic profiles in patients with a preexisting poor left ventricular ejection fraction., Methods: Patients (n = 29; 66 +/- 2 years) with a reduced left ventricular ejection fraction (37% +/- 2%) were prospectively randomized in a blinded fashion, at the time of elective coronary revascularization or valve replacement requiring cardiopulmonary bypass, to infusion of the highly selective and potent endothelin-A subtype receptor antagonist sitaxsentan at 1 or 2 mg/kg (intravenous bolus; n = 9, 10 respectively) or vehicle (saline; n = 10). Infusion of the endothelin-A subtype receptor antagonist/vehicle was performed immediately before separation from cardiopulmonary bypass and again at 12 hours after cardiopulmonary bypass. Endothelin and hemodynamic measurements were performed at baseline, at separation from cardiopulmonary bypass (time 0), and at 0.5, 6, 12, and 24 hours after cardiopulmonary bypass., Results: Baseline plasma endothelin (4.0 +/- 0.3 fmol/mL) was identical across all 3 groups, but when compared with preoperative values, baseline values obtained from age-matched subjects with a normal left ventricular ejection fraction (n = 37; left ventricular ejection fraction > 50%) were significantly increased (2.9 +/- 0.2 fmol/mL, P < .05). Baseline systemic (1358 +/- 83 dynes/sec/cm(-5)) and pulmonary (180 +/- 23 dynes/sec/cm(-5)) vascular resistance were equivalent in all 3 groups. As a function of time 0, systemic vascular resistance changed in an equivalent fashion in the post-cardiopulmonary bypass period, but a significant endothelin-A subtype receptor antagonist effect was observed for pulmonary vascular resistance (analysis of variance; P < .05). For example, at 24 hours post-cardiopulmonary bypass, pulmonary vascular resistance increased by 40 dynes/sec/cm(-5) in the vehicle group but directionally decreased by more than 40 dynes/sec/cm(-5) in the 2 mg/kg endothelin-A subtype receptor antagonist group (P < .05). Total adverse events were equivalently distributed across the endothelin-A subtype receptor antagonist/placebo groups., Conclusion: These unique findings demonstrated that infusion of an endothelin-A subtype receptor antagonist in high-risk patients undergoing cardiac surgery was not associated with significant hemodynamic compromise. Moreover, the endothelin-A subtype receptor antagonist favorably affected pulmonary vascular resistance in the early postoperative period. Thus, the endothelin-A subtype receptor serves as a potential pharmacologic target for improving outcomes after cardiac surgery in patients with compromised left ventricular function., (Copyright 2010 The American Association for Thoracic Surgery.

Introduction: There are few published guidelines for the management of sexual dysfunctions in men and women, despite the prevalence and lack of attention to these problems. Disorders of sexual function in men include erectile dysfunction, orgasm/ejaculation disorders, priapism, and Peyronie's disease., Aim: To provide evidence-based and expert-opinion consensus guidelines for the clinical management of men's sexual dysfunctions., Methods: An International Consultation in collaboration with major urological and sexual medicine societies assembled over 200 multidisciplinary experts from 60 countries into 17 consultation committees. Committee members established the scope and objectives for each chapter. Following intensive review of available data and publications, committees developed evidence-based guidelines in each area., Main Outcome Measure: New algorithms and guidelines for assessment and treatment of men's sexual dysfunction were developed. The Oxford system of evidence-based review was systematically applied. Expert opinion was based on systematic grading of the medical literature, in addition to cultural and ethical considerations., Results: Recommendations and guidelines for men's sexual dysfunction are presented. These guidelines were developed as evidence-based, patient-centered, and multidisciplinary in focus. For the clinical assessment and diagnosis of ED, a basic evaluation was recommended for all patients, with optional and specialized testing reserved for special cases. A new treatment algorithm is proposed. This algorithm provides a clinically relevant guideline for managing ED in the large majority of men. New treatment guidelines and algorithms are provided for men's orgasm and ejaculation disorders, including premature ejaculation, retrograde and delayed ejaculation. Finally, expert opinion-based guidelines for the clinical management of priapism and Peyronie's disease are provided., Conclusions: Additional research is needed to validate and extend these guidelines. Nonetheless, this summary encompasses the recommendations concerning men's sexual dysfunctions presented at the 2nd International Consultation on Sexual Medicine in Paris, France, June 28-July 1, 2003.
