Developing nations have many challenges to the growth of emergency medical systems. This development in Afghanistan is also complicated by many factors that plague post-conflict countries including an unstable political system, poor economy, poor baseline health indices, and ongoing violence. Progress has been made in Afghanistan with the implementation of the Basic Package of Health Service (BPHS) by the Ministry of Public Health in an effort to provide healthcare that would have the most cost-effective impact on common health problems. Trauma and trauma-related disability were both identified as priorities under the BPHS, and efforts have begun to address these problems. Most of the emergency care delivered in Afghanistan is provided by the military sector and non-governmental organizations. Security, lack of infrastructure, economic hardship, difficult access to healthcare facilities, poor healthcare facility conditions, and lack of trained healthcare providers, especially women, are all problems that need to be addressed. The long-term goal of quality healthcare for all Afghan citizens will only be met by a combination of specific goal-oriented projects, foreign aid, domestic responsibility, and time.

BACKGROUND/OBJECTIVES: Age-related hearing loss (ARHL) is a widely prevalent yet manageable condition that has been linked to neurocognitive and psychiatric comorbidities. Multiple barriers hinder older individuals from being diagnosed with ARHL through pure-tone audiometry. This is especially true during the COVID-19 pandemic, which has resulted in the closure of many outpatient audiology and otolaryngology offices. Smartphone-based hearing assessment apps may overcome these challenges by enabling patients to remotely self-administer their own hearing examination. The objective of this review is to provide an up-to-date overview of current mobile health applications (apps) that claim to assess hearing. DESIGN: Narrative review. MEASUREMENTS: The Apple App Store and Google Play Store were queried for apps that claim to assess hearing. Relevant apps were downloaded and used to conduct a mock hearing assessment. Names of included apps were searched on four literature databases (PubMed/MEDLINE, EMBASE, Cochrane Library, and CINAHL) to determine which apps had been validated against gold standard methods. RESULTS: App store searches identified 44 unique apps. Apps differed with respect to the type of test offered (e.g., hearing threshold test), cost, strategies to reduce ambient noise, test output (quantitative vs qualitative results), and options to export results. Validation studies were identified for seven apps. CONCLUSION: Given their low cost and relative accessibility, smartphone-based hearing apps may facilitate screening for ARHL, particularly in the setting of limitations on in-person medical care due to COVID-19. However, app features vary widely, few apps have been validated, and user-centered designs for older adults are largely lacking. Further research and validation efforts are necessary to determine whether smartphone-based hearing assessments are a feasible and accurate screening tool for ARHL.

Age-related hearing loss (HL), a common and undertreated condition, has been linked to morbid conditions, including dementia, cognitive impairment, 1 and depression. 2 While studies have measured the prevalence of HL in general, 3 or in the older old (≥80 years) as a single group, 4,5 an accurate population-level estimate does not exist for those 80 years and older. This is because population-level databases either exclude or mask upper age extremes to protect anonymity. This precludes specifically studying HL epidemiology in older old individuals, the very group most affected by HL.We obtained access to the true age of older old individuals in the National Health and Nutrition Examination Survey (NHANES) through a specialized security clearance process. To our knowledge, this represents the first nationally representative characterization of HL prevalence in the older old population.

Age-related hearing loss (ARHL) has been connected to both cognitive decline and late-life depression. Several mechanisms have been offered to explain both individual links. Causal and common mechanisms have been theorized for the relationship between ARHL and impaired cognition, including dementia. The causal mechanisms include increased cognitive load, social isolation, and structural brain changes. Common mechanisms include neurovascular disease as well as other known or as-yet undiscovered neuropathologic processes. Behavioral mechanisms have been used to explain the potentially causal association of ARHL with depression. Behavioral mechanisms include social isolation, loneliness, as well as decreased mobility and impairments of activities of daily living, all of which can increase the risk of depression. The mechanisms underlying the associations between hearing loss and impaired cognition, as well as hearing loss and depression, are likely not mutually exclusive. ARHL may contribute to both impaired cognition and depression through overlapping mechanisms. Furthermore, ARHL may contribute to impaired cognition which may, in turn, contribute to depression. Because ARHL is highly prevalent and greatly undertreated, targeting this condition is an appealing and potentially influential strategy to reduce the risk of developing two potentially devastating diseases of later life. However, further studies are necessary to elucidate the mechanistic relationship between ARHL, depression, and impaired cognition.

Objectives/Hypothesis To analyze the association between early audiometric age‐related hearing loss and brain β‐amyloid, the pathologic hallmark of Alzheimer's disease (AD). Study Design Cross‐sectional analysis of a prospective cohort study. Methods A cross‐sectional analysis was performed on 98 participants in a cohort study of hearing and brain biomarkers of AD. The primary outcome was whole brain β‐amyloid standardized uptake value ratio (SUVR) on positron emission tomography (PET). The exposure was hearing, as measured by either pure‐tone average or word recognition score in the better ear. Covariates included age, gender, education, cardiovascular disease, and hearing aid use. Linear regression was performed to analyze the association between β‐amyloid and hearing, adjusting for potentially confounding covariates. Results The mean age ± standard deviation was 64.6 ± 3.5 years. In multivariable regression, adjusting for demographics, education, cardiovascular disease, and hearing aid use, whole brain β‐amyloid SUVR increased by 0.029 (95% confidence interval [CI]: 0.003‐0.056) for every 10 dB increase in pure‐tone average (P = .030). Similarly, whole brain β‐amyloid SUVR increased by 0.061 (95% CI: 0.009‐0.112) for every 10% increase in word recognition score (P = .012). Conclusions Worsening hearing was associated with higher β‐amyloid burden, a pathologic hallmark of AD, measured in vivo with PET scans. Level of Evidence 3 Laryngoscope, 131:633–638, 2021
