Examination of Factors Affecting the Likelihood of Whether Individuals Would Purchase Cartilage Conduction Hearing Aids.

Cartilage conduction hearing aids (CC-HAs) are a novel type of hearing aid relying on cartilage conduction, the so-called third auditory conduction pathway. However, CC-HAs have only recently entered routine clinical use, and therefore data on their usefulness are lacking. The purpose of this study was to examine the possibility of assessing whether individual patients would show good adaptation to CC-HAs. Thirty-three subjects (41 ears in total) underwent a free trial of CC-HAs. Age, disease category, and the pure-tone threshold of air and bone conduction, unaided field sound threshold, aided field sound threshold, and functional gain (FG) at 0.25, 0.5, 1, 2, and 4 kHz were compared between patients who subsequently purchased and did not purchase the CC-HAs. Overall, 65.9% of the subjects purchased CC-HAs after the trial. In comparison to non-purchasers, those who decided to purchase CC-HAs showed better pure tone hearing thresholds at high frequencies for both air conduction (2 and 4 kHz) and bone conduction (1, 2, and 4 kHz), as well as for aided thresholds in the sound field (1, 2, and 4 kHz) when using CC-HAs. Therefore, the high-frequency hearing thresholds of subjects trialing CC-HAs might be helpful for identifying those who are likely to benefit from them.

Early enteral nutrition after head and neck surgery with free tissue transfer reconstruction.

OBJECTIVE: Early enteral nutrition is essential for enhancing recovery after surgery. However, to date, no detailed study has been conducted on the feasibility of early enteral nutrition in patients undergoing head and neck surgery with free tissue transfer reconstruction (HNS-FTTR) and the risk factors for difficulty with early enteral nutrition. METHODS: We retrospectively analyzed 102 patients who underwent HNS-FTTR at our institution; 61 underwent free jejunal reconstruction (FJ) and 41 did not. We investigated the achievement of early enteral nutrition within 24 and 48 h after surgery and the discontinuation of enteral nutrition after its initiation within 7 days after surgery. RESULTS: Enteral nutrition could be started in 81/102 (79.4%) and 99/102 (97.1%) patients within 24 and 48 h, respectively. Cases of difficulty with early enteral nutrition accounted for 21/102 (20.6%) patients. The multivariate analysis revealed that FJ was a significant independent risk factor for difficulty with early enteral nutrition (odds ratio: 4.054, P = 0.042). The risk factors for difficulty with early enteral nutrition in patients who underwent FJ were also investigated, and the multivariate analysis showed that blood loss of ≥158 mL was a significant independent risk factor (odds ratio: 3.505, P = 0.044). CONCLUSIONS: Early enteral nutrition seemed to be provided with no problems in patients without FJ. FJ was a significant risk factor for difficulty with early enteral nutrition. Increased intraoperative blood loss was a significant risk factor for difficulty with early enteral nutrition in patients undergoing FJ; therefore, patients' abdominal symptoms and gastric residual volume should be carefully monitored in such cases.

Characteristics of aspiration pneumonia patients in acute care hospitals: A multicenter, retrospective survey in Northern Japan.

BACKGROUND: Pneumonia is a common cause of illness and death of the elderly in Japan. Its prevalence is escalating globally with the aging of population. To describe the latest trends in pneumonia hospitalizations, especially aspiration pneumonia (AP) cases, we assessed the clinical records of pneumonia patients admitted to core acute care hospitals in Miyagi prefecture, Japan. METHODS: A retrospective multi-institutional joint research was conducted for hospitalized pneumonia patients aged ≥20 years from January 2019 to December 2019. Clinical data of patients were collected from the medical records of eight acute care hospitals. RESULTS: Out of the 1,800 patients included in this study, 79% of the hospitalized pneumonia patients were aged above 70 years. The most common age group was in the 80s. The ratio of AP to total pneumonia cases increased with age, and 692 out of 1,800 patients had AP. In univariate analysis, these patients had significantly older ages, lower body mass index (BMI), a lower ratio of normal diet intake and homestay before hospitalization, along with more AP recurrences and comorbidities. During hospitalization, AP patients had extended fasting periods, more swallowing assessments and interventions, longer hospitalization, and higher in-hospital mortality rate than non-AP patients. A total of 7% and 2% AP patients underwent video endoscopy and video fluorography respectively. In multivariate analysis, lower BMI, lower C-reactive protein, a lower ratio of homestay before hospitalization, a higher complication rate of cerebrovascular disease, dementia, and neuromuscular disease were noted as a characteristic of AP patients. Swallowing interventions were performed for 51% of the AP patients who had been hospitalized for more than two weeks. In univariate analysis, swallowing intervention improved in-hospital mortality. Lower AP recurrence before hospitalization and a lower ratio of homestay before hospitalization were indicated as characteristics of AP patients of the swallowing intervention group from multivariate analysis. Change in dietary pattern from normal to modified diet was observed more frequently in the swallowing intervention group. CONCLUSION: AP accounts for 38.4% of all pneumonia cases in acute care hospitals in Northern Japan. The use of swallowing evaluations and interventions, which may reduce the risk of dysphagia and may associate with lowering mortality in AP patients, is still not widespread.
