Cardiomyopathy: Evaluating Disparities in Place of Death in the United States Using the CDC Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) Database Over 22 Years.

Background The human experience involves the inevitable end of life, whether sudden or expected. Ensuring a dignified end-of-life encounter necessitates understanding influential factors. Cardiomyopathy, a group of heart muscle diseases, has varying mortality implications, including heart failure and arrhythmias. Disparities in place of death (hospital, home, or hospice) can significantly alter the end-of-life care for a patient. Methods The aim of this study is to identify variations in death locations for U.S. cardiomyopathy patients between 1999 and 2020, based on age, gender, race, and census region, utilizing the CDC WONDER ( CDC Wide-Ranging Online Data for Epidemiologic Research) database, which contains a wide array of public health information. Data were categorized by age, gender, race, and location, and further subcategorized according to place of death. Statistical analysis was done via R programming software. Result The aggregate data of 528,401 cardiomyopathy-related deaths from 1990 to 2020 were obtained. Findings revealed age, gender, and regional disparities in death location. Notably, cardiomyopathy is found to be prevalent in the 75+ years age group, male gender, and people belonging to Caucasian descent, and maximal in the Southern census area. The study's logistic regression analysis unveiled a significant association between demographic factors and death locations. Conclusion This research underscores the significance of understanding disparities in the place of death for cardiomyopathy patients, shedding light on demographic influences and paving the way for patient-centered end-of-life care approaches.

Global review reveals how disparate study motivations, analytical designs, and focal ions limit understanding of salinization effects on freshwater animals.

Global salinization of freshwaters is adversely affecting biotic communities and ecosystem processes. We reviewed six decades (1960-2020) of literature published on animal responses to increased salinities across different taxonomic and ecological contexts and identified knowledge gaps. From 585 journal articles, we characterized 5924 responses of mollusks, crustaceans, zooplankton, non-arthropod invertebrates (NAI), insects, fishes, and amphibians to salinization. Insects and fishes were the most studied taxa; Na+ and Cl- were the most studied ions-. Collectively, concentrations of the ions examined typically spanned five orders of magnitude. Species' invasiveness was a key motivation for studying mollusks, crustaceans, and fishes; threats of urbanization and road salts were key motivations for studying NAI, zooplankton, and amphibians. Laboratory studies were more common than field studies for most taxa. Focal life stages in laboratory studies varied widely but juveniles and adults were represented similarly in field studies. Studies of mollusks, NAI, and crustacean focused on adults; studies of zooplankton, insects, fishes, and amphibians focused on juveniles. Organismal- and population-level responses measuring solute uptake, internal chemistry, body condition, or ion concentrations predominated laboratory studies; population- and assemblage-level responses measuring abundance, spatial distribution, or assemblage composition predominated field studies. Negative responses to salinization predominated but positive and unimodal responses were apparent across all taxa and organizational levels. Key topics for further research include a) salinity responses by more taxa, b) responses to especially toxic ions (i.e., potassium, bicarbonate, sulfate, magnesium), c) mechanisms causing positive and unimodal responses, d) traits underpinning responses, e) effects transcending organizational levels, f) ion-specific response thresholds, and g) interactions between salinity and other stressors. Our review suggests inter-taxa variation in sensitivity to salinization reflects occurrence of certain biological traits, including gill-breathing, semi-permeable skin, multiple life stages, and limited mobility. We propose a traits-based framework to predict salinization sensitivity from shared traits. This evolutionary approach could inform management aimed at preventing or reducing adverse impacts of freshwater salinization.

Interaction between age and gender on survival outcomes in extramedullary multiple myeloma over the past two decades.

BACKGROUND: Extramedullary multiple myeloma (MM) (EMM) is a rare and aggressive subentity of MM that can be present at diagnosis or develop anytime during the disease course. There is a paucity of data on the clinical characteristics and overall epidemiology of EMM. Furthermore, there is a scarcity of data on how the interaction of age and gender influences the survival of EMM. AIM: To evaluate the clinical characteristics of patients with EMM over the past 2 decades and to identify epidemiologic characteristics that may impact overall prognosis. METHODS: A total of 858 patients diagnosed with EMM, between 2000 and 2017, were ultimately enrolled in our study by retrieving the Surveillance, Epidemiology, and End Results database. We analyzed demographics, clinical characteristics, and overall mortality (OM) as well as cancer-specific mortality (CSM) of EMM. Variables with a P value < 0.1 in the univariate Cox regression were incorporated into the multivariate Cox model to determine the independent prognostic factors, with a hazard ratio (HR) of greater than 1 representing adverse prognostic factors. RESULTS: From a sample of 858 EMM, the male gender (63.25%), age range 60-79 years (51.05%), and non-Hispanic whites (66.78%) were the most represented. Central Nervous System and the vertebral column was the most affected site (33.10%). Crude analysis revealed higher OM in the age group 80+ [HR = 6.951, 95% confidence interval (95%CI): 3.299-14.647, P = 0], Non-Hispanic Black population (HR = 1.339, 95%CI: 1.02-1.759, P = 0.036), Bones not otherwise specified (NOS) (HR = 1.74, 95%CI: 1.043-2.902, P = 0.034), and widowed individuals (HR = 2.107, 95%CI: 1.511-2.938, P = 0). Skin involvement (HR = 0.241, 95%CI: 0.06-0.974, P = 0.046) and a yearly income of $75000+ (HR = 0.259, 95%CI: 0.125-0.538, P = 0) had the lowest OM in the crude analysis. Crude analysis revealed higher CSM in the age group 80+, Non-Hispanic Black, Bones NOS, and widowed. Multivariate cox proportional hazard regression analyses only revealed higher OM in the age group 80+ (HR = 9.792, 95%CI: 4.403-21.774, P = 0) and widowed individuals (HR = 1.609, 95%CI: 1.101-2.35, P = 0.014). Multivariate cox proportional hazard regression analyses of CSM also revealed higher mortality of the same groups. Eyes, mouth, and ENT involvement had the lowest CSM in the multivariate analysis. There was no interaction between age and gender in the adjusted analysis for OM and CSM. CONCLUSION: EMM is a rare entity. To our knowledge, there is a scarcity of data on the clinical characteristics and prognosis factors of patients with extramedullary multiple myeloma. In this retrospective cohort, using a United States-based population, we found that age, marital status, and tumor site were independent prognostic factors. Furthermore, we found that age and gender did not interact to influence the mortality of patients with EMM.

New approach in programming sequentially implanted children: Towards balanced dynamic ranges (DR).

There is a tendency for children undergoing sequential cochlear implant after a long period of unilateral implant use to have a smaller dynamic range in their second implant compared to their first implant. This study aimed to investigate if balancing the dynamic ranges between the two implants influenced functional outcomes in sequentially implanted children. Nineteen participants with long inter-implant time delays were randomly assigned to a study group or a control group. Children in the study group received progressive minimal changes to both first and second implants over a period of nine months to achieve balanced dynamic ranges, while the children in the control group received only changes to their sequential implant. Functional outcomes were collected 24-months after sequential implantation and consisted of speech discrimination scores, spatial localisation, device use and quality of life measures. Results show that spatial discrimination skills improved over time for both groups of children; however children in the study group had smaller localisation errors compared with the children in the control group. No other differences between the two groups were observed. Balanced dynamic ranges in sequentially implanted children can contribute to better performance, particularly in spatial discrimination tasks that rely in inter-aural level differences.

Sequential bilateral implantation in older children: Inter-implant map differences and their effects on functional outcomes.

OBJECTIVES: It is well established that sequential bilateral implantation offers functional benefits in speech in noise and sound localisation, although it can be challenging to get long-term unilateral users to adapt to the second implant. The aim of this study was to investigate programming differences between the two cochlear implants that can impact on performance outcomes. DESIGN: Cohort Study. PARTICIPANTS: Sixteen older children who received sequential implants in Ireland and with at least one-year experience with their sequential implant were included in this study. Children were categorised into two groups according to the time interval between the two implants: short if the time between the two implants was less than eight years and long if more than eight years. MAIN OUTCOME MEASURES: Dynamic ranges and current levels were compared for both implants. Functional outcome measures included sentence discrimination in quiet and in noise and sound localisation. RESULTS: Results show that for the children with long inter-implant delays, the dynamic range of their second implant was on average 34% less than the dynamic range of their first implant. This difference was driven by smaller comfort levels in the second implant compared to the first. Children with longer inter-implant delays also show lower speech discrimination scores with their second implant compared to children with shorter delays, in addition to no bilateral advantage in speech in noise, that is their performance in unilateral mode does not differ from the performance in bilateral mode. Finally, children with longer delays demonstrate poor performance in sound localisation compared to the children with shorter delays. CONCLUSION: Sequentially implanted older children show limited functional benefits from the second implant. The observed functional benefits are determined both by a short inter-implant delay and by having balanced dynamic ranges between the two implants.

Impact of Universal Newborn Hearing Screening on cochlear implanted children in Ireland.

OBJECTIVES: Cochlear Implant (CI) is an established treatment for severe to profound hearing loss (HL). Early diagnosis and intervention in HL are crucial in order to provide access to sound and increase the likelihood of spoken language development in pre-lingually deaf children. In April 2011, the Health Service Executive (HSE) implemented the Universal Newborn Hearing Screening (UNHS) in a phased regional basis in Ireland. This study aimed to investigate the general clinical pathway for UNHS referrals to the CI service and to evaluate the impact of earlier referrals via UNHS on functional outcomes in children. METHODS: The first part of this study constituted a retrospective review of 100 children referred to the National Hearing Implant and Research Centre (NHIRC) via UNHS from November 2011 to December 2016. Implanted children referred via UNHS were categorised into three groups according to their medical status. Their clinical pathway to cochlear implantation was evaluated. Functional outcomes were investigated based on medical and developmental status, respectively. In the second part of this study, developmentally healthy implanted children referred post-UNHS were compared with medically healthy children referred pre-UNHS under the age of four, from January 2005 to June 2011. Current implant status of children, age at referral and functional outcomes were investigated. RESULTS: Medically healthy children were referred to the NHIRC at an earlier age than the medically complex children (2.8 months vs 5.2 months, p < 0.01) and the children presenting with auditory neuropathy spectrum disorder (ANSD) (2.8 months vs 5.3 months, p < 0.01). On average they attended their first appointment and were implanted at a younger age than the ANSD group (6.1 months vs 10.1 months, p < 0.01; 16.3 months vs 29.4 months, p < 0.001, respectively). Developmentally healthy children had significantly better functional outcomes than children with developmental delays. Children referred via UNHS were referred and implanted at a younger age than those referred pre-UNHS. The former group achieved better Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) scores 2 years post-implantation. CONCLUSION: UNHS in Ireland is an important platform for earlier diagnosis and management of congenital HL and our results show that early intervention has a positive impact on functional outcomes in children.

Occurrence of major complications after cochlear implant surgery in Ireland.

OBJECTIVES: Cochlear implantation (CI) is considered an effective and relatively safe procedure for patients with severe-profound hearing loss. However, severe complications are reported in several studies. The purpose of this study was to report the frequency and management of major complications following CI surgery at the National CI Programme (NCIP) in Ireland. METHODS: Major complications were defined according to the classification of Hansen et al. 2010. The medical records of 1017 patients undergoing CI between 1995 and 2016 were analyzed retrospectively for major complications. In addition, radiological and intraoperative findings as well as therapeutic management of all patients with a major complication were reviewed. RESULTS: Altogether, 1017 patients underwent 1266 CI surgeries. The median follow-up of all CI surgeries was 44 months. The total number of major complications identified was 21 which corresponds to an overall rate of 1.7%. The majority of major complication (71%) occurred at least one week after surgery. The most common major complications were internal receiver/stimulator protrusion and migration (6/21), followed by migration of the electrode array (4/21) and recurrent otitis media requiring re-implantation (4/21). All patients with major complications required additional surgery, with reimplantation necessary in 19 patients (90%). DISCUSSION: CI surgery is a safe surgical procedure for hearing rehabilitation associated with a low rate of severe complications. However, major complications can occur many years after surgery, making revision surgery necessary. CONCLUSION: Long-term follow-up is necessary for the early identification of complications to facilitate appropriate care.
