Cochlear implants and hearing aids may facilitate the development of listening and spoken language (LSL) in deaf/hard of hearing young children, but they require aural rehabilitation therapy-often unavailable outside urban areas-for optimal outcomes. This trial assessed the relative effectiveness of LSL therapy delivered either in person or by interactive video. The hypothesis was that telehealth service delivery would be noninferior to in-person therapy.

Half-bridge silicon strain gauges are widely used in the fabrication of diaphragm-type high-pressure sensors, but in some applications, they suffer from low output sensitivity because of mounting position constraints. Through a special design and fabrication approach, a new half-bridge silicon strain gauge comprising one arc gauge responding to tangential strain and another linear gauge measuring radial strain was developed using Silicon-on-Glass (SiOG) substrate technology. The tangential gauge consists of grid patterns, such as the reciprocating arc of silicon piezoresistors on a thin glass substrate.

Currently, silicon-strain-gauge-based diaphragm pressure sensors use four single-gauge chips for high-output sensitivity. However, the four-single-gauge configuration increases the number of glass frit bonds and the number of aluminum wire bonds, reducing the long-term stability, reliability, and yield of the diaphragm pressure sensor. In this study, a new design of general-purpose silicon strain gauges was developed to improve the sensor output voltage while reducing the number of bonds.

Background: Asthma exacerbations with respiratory failure (AERF) are associated with hospital mortality of 7% to 15%. Extracorporeal membrane oxygenation (ECMO) has been used as a salvage therapy for refractory AERF, but controlled studies showing its association with mortality have not been performed.

Research Question: Is treatment with ECMO associated with lower mortality in refractory AERF compared with standard care?

Study Design And Methods: This is a retrospective, epidemiologic, observational cohort study using a national, administrative data set from 2010 to 2020 that includes 25% of US hospitalizations.

Objective: Older hospitalized adults with an existing diagnosis of cancer rarely receive cancer treatment after discharge to a skilled nursing facility (SNF). It is unclear to what degree these outcomes may be driven by cumulative effects of previous cancer treatment and their complications vs an absolute functional threshold from which it is not possible to return. We sought to understand post-acute care outcomes of adults newly diagnosed with cancer and explore functional improvement during their SNF stay.

Background: Twenty-five percent to 45% of COPD is caused by exposures other than active smoking. Secondhand tobacco smoke (SHS) has been suggested as an independent cause of COPD, based on its association with increased respiratory symptoms and a small decrease in lung function, but its impact on respiratory health and lung function after exposure cessation has not been explored.

Research Question: What are the consequences of airline SHS exposure on respiratory health and lung function decades after cessation?

Study Design And Methods: We performed a cohort study involving flight attendants because of their exposure to SHS that stopped > 20 years ago.

Background: Up to 50% of chronic obstructive pulmonary disease (COPD) patients do not receive recommended care for COPD. To address this issue, we developed Proactive Integrated Care (Proactive iCare), a health care delivery model that couples integrated care with remote monitoring.

Methods: We conducted a prospective, quasi-randomized clinical trial in 511 patients with advanced COPD or a recent COPD exacerbation, to test whether Proactive iCare impacts patient-centered outcomes and health care utilization.

Background: After discharge from an acute care hospitalization, patients with cancer may choose to pursue rehabilitative care in a skilled nursing facility (SNF). The objective of this study was to examine receipt of anticancer therapy, death, readmission, and hospice use among patients with cancer who discharge to an SNF compared with those who are functionally able to discharge to home or home with home healthcare in the 6 months after an acute care hospitalization.

Methods: A population-based cohort study was conducted using the SEER-Medicare database of patients with stage II-IV colorectal, pancreatic, bladder, or lung cancer who had an acute care hospitalization between 2010 and 2013.

The surprise question (SQ), "Would you be surprised if your patient died within a year?", has been studied in the cancer population as a prognostic prompt. Studies have almost exclusively directed the SQ to physicians, whereas perspectives of nurses remain underevaluated. We asked the SQ for patients admitted to an inpatient medical oncology service to medical oncology, palliative care, and hospital medicine teams and bedside nurses.

Importance: Strategies to increase access to palliative care, particularly for racial/ethnic minorities, must maximize primary palliative care and community-based models to meet the ever-growing need in a culturally sensitive and congruent manner.

Objective: To investigate if a culturally tailored patient navigator intervention can improve palliative care outcomes for Latino adults with advanced cancer.

Design, Setting, And Participants: The Apoyo con Cariño (Support With Caring) randomized clinical trial was conducted from July 2012 to March 2016.

Latinos are more likely to experience uncontrolled pain, and institutional death, and are less likely to engage in advance care planning. Efforts to increase access to palliative care must maximize primary palliative care and community based models to meet the ever-growing need in a culturally sensitive and congruent manner. Patient navigator interventions are community-based, culturally tailored models of care that have been successfully implemented to improve disease prevention, early diagnosis, and treatment.

Background: Prognostication of survival in patients with advanced cancer has been challenging and contributes to poor illness understanding. Prognostic disagreement occurs even among providers and is a less studied phenomenon.

Objective: We introduced the surprise question (SQ), "Would I be surprised if this patient died in the next 1 year, 6 months, and 1 month?," at multidisciplinary rounds to increase palliative care referrals through the introduction of this prognostic prompt.

Introduction: Tobacco use is common among people who have been in prison. The relationship between social stressors, risky health behaviours, and smoking cessation has not been studied in people recently released from prison. Studying this relationship could yield information that guides strategic and cost-effective tobacco cessation interventions for an under-resourced population.

The aims of this study were to (a) describe the nature of patients' goals upon discharge from hospital, family caregivers' goals for their loved ones, and family caregivers' goals for themselves; (b) determine the degree of concordance with respect to the three elicited goals; (c) ascertain goal attainment across the three elicited goals; and (d) examine factors predictive of goal attainment. Our findings support the position that eliciting patient and family caregiver goals and promoting goal attainment may represent an important step toward promoting greater patient and family caregiver engagement in their care.
