 Speech-in-noise tests have become a valuable part of the audiometric test battery providing an indication of a listener's ability to function in background noise. A simple digits-in-noise (DIN) test could be valuable to support diagnostic hearing assessments, hearing aid fittings and counselling for both paediatric and adult populations. Objective: The objective of this study was to evaluate the South African English smartphone DIN test's performance as part of the audiometric test battery. Design: This descriptive study evaluated 109 adult subjects (43 male and 66 female subjects) with and without sensorineural hearing loss by comparing pure-tone air conduction thresholds, speech recognition monaural performance scores (SRS dB) and the DIN speech reception threshold (SRT)...

The Petri dish and microtiter plate are the golden standard for selection and screening of bacteria in microbiological research. To improve on the limited resolution and throughput of these methods, we developed a universal, user-friendly platform for selection and high-resolution phenotypic screening based on the nanowell slide. This miniaturized platform has an optimal ratio between throughput and assay complexity, holding 672 nanowells of 500 nl each. As monoclonality is essential in bacterial genetics, we used FACS to inoculate each nanowell with a single bacterium in 15 min...

The present study retrospectively analyses the prevalence of late diagnosis in patients with newly-diagnosed HIV infection in Lodz, Poland from January 2009 to December 2016, and assesses the predictive factors associated with late presenters. Late presentation is defined as a diagnosis of HIV with a CD4 count<350 cells/μL, or the occurrence of an AIDS- defining event, regardless of the CD4 cell count. Two hundred and fifty-nine (62.86%) patients were late presenters, 178 of whom (68.72%) were advanced late presenters (CD4 cell count below 200 cells/μL)...

Cochlear implants (CIs) often work very well for many children and adults with profound sensorineural (SNHL) hearing loss. Unfortunately, while many CI patients display substantial benefits in recognizing speech and understanding spoken language following cochlear implantation, a large number of patients achieve poor outcomes. Understanding and explaining the reasons for poor outcomes following implantation is a very challenging research problem that has received little attention despite the pressing clinical significance...

Juan Huang, Janice Chang, Fan-Gang Zeng
Objective: Electro-acoustic stimulation (EAS) is an effective method to enhance cochlear-implant performance in individuals who have residual low-frequency acoustic hearing. To help the majority of cochlear implant users who do not have any functional residual acoustic hearing, electro-tactile stimulation (ETS) may be used because tactile sensation has a frequency range and perceptual capabilities similar to that produced by acoustic stimulation in the EAS users. Methods: Following up the first ETS study showing enhanced English sentence recognition in noise,1 the present study evaluated the effect of ETS on Mandarin tone recognition in noise in two groups of adult Mandarin-speaking individuals...

Background: The cochlear implant has become the standard of care for severe or worse losses in hearing and indeed has produced the first substantial restoration of a lost or absent human sense using a medical intervention. However, the devices are not perfect and many efforts to narrow the remaining gaps between prosthetic and normal hearing are underway. Objective: To assess the present status of cochlear implants and to describe possibilities for improving them...

Developing low-cost and simple electrochemical systems is becoming increasingly important but still challenged for multiplex experiments. Here we report a single-electrode electrochemical system (SEES) using only one electrode not only for a single experiment but also for multiplex experiments based on a resistance induced potential difference. SEESs for a single experiment and multiplex experiments are fabricated by attaching a self-adhesive label with a hole and multiple holes onto an ITO electrode, respectively...

Acute suppurative thyroiditis (AST) is an uncommon, potentially life-threatening cause of a rapidly enlarging neck mass. It may present similarly to subacute thyroiditis, a relatively benign and self-limiting condition. We report a case of AST in an adult intravenous (IV) drug user with a preexisting goiter who presented with a left forearm abscess that grew methicillin-sensitive Staphylococcus aureus . In this particular case, clinical suspicion for AST was high. As a result, early IV antibiotic therapy was initiated, and this led to rapid clinical improvement furthermore preventing airway compromise...

INTRODUCTION: Studies have highlighted the importance of life satisfaction or, more generally, happiness, on health. However, there are few studies that have prospectively assessed the relationship between life satisfaction and healthcare utilization and costs. METHODS: Participants were from three national survey cycles conducted between 2005 and 2010 to future healthcare utilization up to 2015. Analysis was conducted in 2016-2017. Annual per person costs were calculated and individuals ranked...

BACKGROUND: Social media allows for instant access to, and dissemination of, information around the globe. Access to social media in low- and middle-income countries has increased exponentially in recent years due to technological advances. Despite this growth, the use of social media in low- and middle-income countries is less well-researched than in high-income countries. OBJECTIVE: To identify, explore and summarize the current state of the literature on the use of social media for health in low- and middle-income countries...

BACKGROUND: Patterns in non-medical prescription opioid (NMPO) and heroin use have recently shifted, with evidence that NMPO-only users transition to NMPO and heroin co-use. Co-use is associated with increased risk of morbidity and overdose, highlighting the need for further investigation. This study aims to quantify, describe, and explore trends in co-use. METHODS: Using data from the 2003-2014 National Surveys on Drug Use and Health, we compared co-use to NMPO- and heroin-only use across demographic, substance use and mental health characteristics with chi-squared tests...

Educational assessment for the health professions has seen a major attempt to introduce competency based frameworks. As high level policy developments, the changes were intended to improve outcomes by supporting learning and skills development. However, we argue that previous experiences with major innovations in assessment offer an important road map for developing and refining assessment innovations, including careful piloting and analyses of their measurement qualities and impacts. Based on the literature, numerous assessment workshops, personal interactions with potential users, and our 40 years of experience in implementing assessment change, we lament the lack of a coordinated approach to clarify and improve measurement qualities and functionality of competency based assessment (CBA)...

The relation between speech recognition and within-channel or across-channel (i.e., spectral tilt) intensity discrimination was measured in nine CI users (11 ears). Within-channel intensity difference limens (IDLs) were measured at four electrode locations across the electrode array. Spectral tilt difference limens were measured with (XIDL-J) and without (XIDL) level jitter. Only three subjects could perform the XIDL-J task with the amount of jitter required to limit use of within-channel cues. XIDLs (normalized to %DR) were correlated with speech recognition (r = 0...

OBJECTIVES: The earned income tax credit (EITC), refundable monies for America's working poor, is associated with improved child health. Yet, 20% of eligible families do not receive it. We provided free tax preparation services in clinics serving low-income families and assessed use, financial impact, and accuracy. METHODS: Free tax preparation services ("StreetCred") were available at 4 clinics in Boston in 2016 and 2017. We surveyed a convenience sample of clients ( n = 244) about experiences with StreetCred and previous tax services and of nonparticipants ( n = 100; 69% response rate) and clinic staff ( n = 41; 48% response rate) about acceptability and feasibility...

BACKGROUND: Self-care behaviors are commonly prescribed to manage both cardiovascular disease and hypertension to reduce modifiable risk factors and improve quality of life. Nevertheless, long-term adherence to self-care recommendations for cardiac patients has been problematic. In cardiac patients, moderated online forums have been found to be particularly useful in supporting maintenance of heart-healthy diet and fewer hospital visits. As such, we developed the e-Forum, a Web-based moderated forum designed to promote continued user engagement and long-term self-care adherence...
