Abstract
OBJECTIVE The sequential generation of swallowing pressure (SP) from the nasopharynx to the proximal esophagus is important for the bolus to pass from the oral cavity to the esophagus. The purpose of this study was to investigate the correlation of the SP sequence mode on high-resolution manometry (HRM) with oral intake difficulty and aspiration pneumonia. METHODS Consecutive patients with dysphagia who were admitted to our dysphagia clinic between November 2016 and November 2020 were enrolled in this cross-sectional study. We classified the HRM pressure topography data according to the SP sequence mode into type A, normal; B, partially decreased; C, totally decreased; and D, sequence disappeared, and according to the upper esophageal sphincter (UES) during pharyngeal swallowing into type 1, flattening and 2, non-flattening. Clinical dysphagia severity was determined based on oral intake difficulty and aspiration pneumonia. RESULTS In total, 202 patients with dysphagia (mean [standard deviation] age, 68.3 [14.5] years; 140 [69.8%] male) were enrolled. Type C (odds ratio [OR], 10.48; 95% confidence interval [CI], 2.89-51.45), type D (OR, 19.90; 95% CI, 4.18-122.35), and type 2 (OR, 6.36; 95% CI, 2.88-14.57) were significantly related to oral intake difficulty. Type C (OR, 3.23; 95% CI, 1.08-11.12) and type 2 (OR, 4.18; 95% CI, 1.95-9.15) were significantly associated with aspiration pneumonia. CONCLUSION The failure of sequential generation of SP was associated with higher risk of oral intake difficulty and aspiration pneumonia. These assessments are useful in understanding the pathophysiology and severity of dysphagia and in selecting safety nutritional management methods.

Abstract
After a stroke, most patients have dysphagia, which can lead to aspiration pneumonia, malnutrition, and adverse functional outcomes. Protective interventions aimed at reducing these complications remain the cornerstone of treatment. Dietary adjustments and oral hygiene help mitigate the risk of aspiration pneumonia, and nutritional supplementation, including tube feeding, might be needed to prevent malnutrition. Rehabilitative interventions aim to enhance swallowing function, with different behavioural strategies showing promise in small studies. Investigations have explored the use of pharmaceutical agents such as capsaicin and other Transient-Receptor-Potential-Vanilloid-1 (TRPV-1) sensory receptor agonists, which alter sensory perception in the pharynx. Neurostimulation techniques, such as transcranial direct current stimulation, repetitive transcranial magnetic stimulation, and pharyngeal electrical stimulation, might promote neuroplasticity within the sensorimotor swallowing network. Further advancements in the understanding of central and peripheral sensorimotor mechanisms in patients with dysphagia after a stroke, and during their recovery, will contribute to optimising treatment protocols.

Abstract
AIM To evaluate oral frailty features present in hospitalized older patients with aspiration pneumonia. METHODS We enrolled hospitalized patients aged ≥50 years and classified them into three groups: the community-acquired, aspiration, and non-community-acquired pneumonia groups. Oral frailty was defined as meeting three or more criteria from the following: choking, and decreased occlusal force, masticatory function, tongue-lip motor function, tongue pressure, and tongue pressure during swallowing. RESULTS Of 168 patients enrolled, the incidence of aspiration pneumonia was 23.9% (17/71) in patients admitted with pneumonia as the primary diagnosis. The occlusal force and masticatory function were significantly poorer and tongue pressure and tongue pressure during swallowing were significantly lower in the aspiration pneumonia group than in the other two groups. A higher number of chronic comorbidities, poor oral health, and lower tongue pressure during swallowing were significantly associated with aspiration pneumonia. A tongue pressure during swallowing of <10.32 kPa might be a cutoff point for predicting the risk of aspiration pneumonia. CONCLUSIONS Hospitalized patients aged ≥50 years with multiple comorbidities, poor oral hygiene, and oral frailty during swallowing are at a higher risk of developing aspiration pneumonia, especially when their tongue pressure during swallowing is <10.32 kPa. Aspiration pneumonia is a preventable disease. Healthcare professionals should incorporate tongue pressure measurements or other screening tools into routine clinical practice to facilitate the early detection of this condition and intervention.

Abstract
AIM To clarify whether the Whitney Comorbidity Index (WCI) is useful in Asian adults with cerebral palsy (CP) and whether aspiration pneumonia and pressure ulcers improved the prognostic significance of the WCI. METHOD This cohort study evaluated individuals aged at least 18 years with CP in Japan. We used Cox proportional hazards regression to analyse 2-year mortality rates. The predictive performance of the Charlson Comorbidity Index, Elixhauser Comorbidity Index, and WCI were compared as comorbidity assessment criteria. Aspiration pneumonia and pressure ulcers were added to the Cox models, and their impact on hazard ratios was determined. RESULTS Of the 2232 adults with CP, 72 died during the 2 years. The model with a previously reported weighted WCI with aspiration pneumonia and pressure ulcers produced the best fit. Additionally, the hazard risk of 2-year mortality for an unweighted WCI score of at least 4 was 2.56; when CP-specific comorbidities were added, it increased to 8.94. INTERPRETATION This study showed that the WCI can be used in Asian adults with CP. Furthermore, assessing patient age, aspiration pneumonia, and pressure ulcers in addition to the WCI increased the predictive value for mortality. Our findings indicate that the WCI can promote valid comparisons between international populations. WHAT THIS PAPER ADDS The Whitney Comorbidity Index (WCI) is useful among adults with cerebral palsy, irrespective of ethnic differences. Assessment of aspiration pneumonia and pressure ulcers increased the WCI predictive value. The WCI helps identify adults with cerebral palsy at risk of adverse outcomes.

Abstract
OBJECTIVES To investigate the impact of early swallowing assessment and rehabilitation on the total oral intake and in-hospital mortality in patients with aspiration pneumonia. METHODS We retrospectively analyzed the data of patients with aspiration admitted between September 1, 2015, and October 31, 2016. The inclusion criterion was total oral intake before admission. A new protocol-based intervention for appropriate early oral intake was implemented on April 1, 2016. The protocol consisted of two steps. First, a screening test was conducted on the day of admission to detect patients who were not at high risk of dysphagia. Second, patients underwent a modified water swallowing test and water swallowing test. Patients cleared by these tests immediately initiated oral intake. The primary outcome, the composite outcomes of no recovery to total oral intake at discharge, and in-hospital mortality were compared between the patients admitted pre- and post protocol intervention. RESULTS A total of 188 patients were included in the analysis (pre-, 92; post-, 96). The primary outcome did not differ between the pre- and post-intervention periods (23/92 [25.0%] vs. 18/96 [18.8%], p = 0.30). After adjusting for other variables, the intervention was significantly associated with a lower risk of composite outcomes (odds ratio, 0.22, 95%CI, 0.08-0.61, p = 0.004). CONCLUSION The new protocol for early swallowing assessment, rehabilitation, and promotion of oral intake in patients admitted with aspiration pneumonia may be associated with the lower risk for the composite outcomes of in-hospital mortality and no recovery to total oral intake.

Abstract
Hyponatremia due to water intoxication is frequently observed in patients with chronic schizophrenia. We herein present a 49-year-old man who developed schizophrenia at the age of 23 and had been admitted to the closed ward of our hospital for 7 years. He was found by a round nurse standing at the bedside, covering both ears with his hands and making groaning noises. He was disoriented and immediately after being returned to bed, a general tonic-clonic seizure occurred. Severe hyponatremia (Na 104 mEq/L) was noted and intravenous sodium correction was started. A few hours later, due to glossoptosis and massive vomiting, ventilation got worse to the point where he had to be put on a ventilator. On the following day, he developed aspiration pneumonia and antimicrobial treatment was started. In addition, a blood sample taken 36 hours later revealed an extensive elevation of creatine kinase (41,286 U/L), pointing to a possibility of rhabdomyolysis as a complication. Subsequently, the general condition gradually improved with antimicrobial therapy and sodium correction. He eventually recovered without any complications including central pontine myelinolysis. He had no history of polydipsia before this event but it was later found that esophageal stricture triggered complusive fluid intake, resulting in acute hyponatremia, seizure, aspiration pneumonia and rhabdomyolysis. A brief discussion will be provided on the issues surrounding hyponatremia, rhabdomyolysis and schizophrenia.

Abstract
BACKGROUND There is a lack of prospective research in South Africa's speech therapy private sector, specifically, in the acute stroke population. There is a need to understand the quality of speech therapy services and outcomes post-stroke in the private sector. OBJECTIVES This prospective cohort study investigated associations between speech, language, and swallowing conditions (i.e. dysarthria, apraxia of speech, aphasia, dysphagia), and outcomes post-stroke (i.e. length of hospital stay [LOS], degree of physical disability according to the Modified Rankin Scale [mRS], functional level of oral intake according to the Functional Oral Intake Scale [FOIS], dehydration, weight loss, aspiration pneumonia, mortality). METHOD A prospective design was used to determine the incidence of speech, language, and swallowing conditions post-stroke. Convenience sampling was used to select participants (N = 68). Various statistical tests were used and the alpha level was set at Bonferroni correction p 0.01. RESULTS Co-occurring speech, language, and swallowing conditions frequently occurred post-stroke (88%). Participants who were referred to speech therapy later than 24 h post-admission (52.94%) stayed in hospital for a median of 3 days longer than those who were referred within 24 h (p = 0.042). Dysphagia was significantly associated with moderate to severe physical disability (p 0.01). Dysphagia with aspiration was significantly associated with poor functional level of oral intake, at admission and at discharge (p 0.01). At discharge, aspiration pneumonia was significantly associated with severe physical disability (p 0.01, r = 0.70). CONCLUSION In South Africa's private sector, co-occurring speech, language, and swallowing conditions commonly occurred post-stroke, and dysphagia was strongly associated with physical disability and poor functional level of oral intake. Length of hospital stay was increased by delayed speech therapy referrals.Contribution: This article contributes data on speech therapy services, communication and swallowing disorders post-stroke, and outcomes in South Africa's private sector.

Abstract
OBJECTIVE (S) Children with bronchopulmonary dysplasia (BPD) are at higher risk of respiratory insufficiency during respiratory illness. We aimed to investigate whether obstructive sleep apnea (OSA) is associated with increased morbidity among children with BPD hospitalized with acute respiratory illnesses. STUDY DESIGN Hospital discharge records were obtained from the Kid's Inpatient Database for children <21 years of age with BPD hospitalized for acute respiratory illness between 1997 and 2012. Acute respiratory illnesses included bacterial and/or viral pneumonia, bronchiolitis, acute upper respiratory tract infections, aspiration pneumonia, or asthma exacerbation. The primary exposure was OSA. The primary outcome was invasive mechanical ventilation (IMV), and secondary outcomes were noninvasive mechanical ventilation (NIMV), length of hospital stay (LOS), and inflation-adjusted cost of hospitalization (IACH). Multivariable regression was conducted to ascertain the associations between OSA and primary and secondary outcomes accounting for BPD-associated comorbidities. RESULTS Among 33,640 hospitalizations of children with BPD for acute respiratory illness, there were 607 (1.8%) cases with comorbid OSA vs. 33,033 (98.2%) controls without OSA. Patients with OSA were more likely to have aspiration pneumonia, central sleep apnea, obesity, laryngeal stenosis, congenital airway, and skull/face/jaw anomalies. Multivariable regression showed that OSA was associated with IMV (OR 1.45, 95% CI 1.09-1.94, p = 0.012) and NIMV (OR 2.61, 95% CI 1.71-3.98, p < 0.001), but not LOS or IACH. CONCLUSIONS In BPD patients hospitalized with acute respiratory illness, having OSA is associated with increased risks for respiratory insufficiency requiring noninvasive or invasive mechanical ventilation. Clinicians should consider OSA, along with other BPD-associated comorbidities, in the management of this population.

Abstract
OBJECTIVES To elucidate the incidence and risk factors for pneumonia after acute traumatic cervical spinal cord injury (CSCI). DESIGN Retrospective cohort study.Setting: Spinal injuries center in Japan.Participants: Of 184 individuals who were admitted within 2 weeks after acute traumatic cervical spinal injuries, 167 individuals who met the criteria were included in this study.Interventions: The occurrence of pneumonia, degree of dysphagia using the Dysphagia Severity Scale, patient age, history of smoking, presence of tracheostomy, vital capacity, level of injury, and the American Spinal Injury Association Impairment Scale (AIS) 2 weeks after injury were assessed.Outcomes: Incidence of pneumonia were analyzed. Moreover, the risk factors of pneumonia were evaluated using logistic regression analysis. RESULTS From the 167 individuals who met the criteria, 30 individuals (18%) had pneumonia; in 26 (87%) of these individuals, pneumonia was aspiration related, defined as Dysphagia Severity Scale ≤ 4. The median occurrence of aspiration pneumonia was 11.5 days after injury. A logistic regression analysis revealed that severe AIS and severe Dysphagia Severity Scale scores were significant risk factors of pneumonia after CSCI. CONCLUSIONS It was highly likely that the pneumonias following CSCI were related to aspiration based on the Dysphagia Severity Scale. In addition, most of the patients developed aspiration pneumonia within 1 month after injury. Aspiration and severe paralysis were significant risk factors for pneumonia. The treatment of dysphagia in the acute phase should be considered an important indicator to prevent pneumonia.

Abstract
BACKGROUND Dysphagia is common in elderly patients with dementia and is one of the common clinical geriatric syndromes. It imposes a heavy burden on patients and their caregivers and is becoming an important public health problem. This study examined the association between dysphagia in older dementia patients in the ICU and the subsequent adverse health outcomes they experience. PATIENTS AND METHODS A retrospective analysis of adults (≥65 years) with dementia in ICUs of a Boston tertiary academic medical center was conducted. Using the International Classification of Diseases' Ninth and Tenth Revisions, dementia patients were identified. The study cohort comprised 1009 patients, median age 84.82 years, 56.6% female, predominantly White (72.9%). Patients were grouped based on swallowing function: dysphagia (n=282) and no-dysphagia (n=727). Dysphagia was identified via positive bedside swallowing screening. Primary outcomes were 90- and 180-day mortality, secondary outcomes included aspiration pneumonia, pressure injury, and delirium. Cohort characteristics were compared using the Wilcoxon rank-sum and chi-square tests. Dysphagia and outcomes correlations were examined via Kaplan-Meier survival analysis, Cox proportional-hazards regression models, logistic regression models, and subgroup analysis. RESULTS After adjusting for covariates, the results from multivariate Cox proportional-hazards regression indicated that dysphagia was significantly associated with increased 90-day (HR=1.36, 95% CI=1.07-1.73, E-value=1.78) and 180-day (HR=1.47, 95% CI=1.18-1.82, E-value=1.94) mortality; the multifactorial logistic regression results indicated that dysphagia was associated with significant increases in pressure injury (OR=1.58, 95% CI=1.11-2.23, E-value=1.83) and aspiration pneumonia occurrence (OR=4.04, 95% CI=2.72-6.01, E-value=7.54), but was not significantly associated with delirium prevalence (OR=1.27, 95% CI=0.93-1.74). CONCLUSION Dysphagia is likely to increase the risk of adverse health outcomes in older adults with dementia in ICU, and these adverse outcomes mostly include 90- and 180-day mortality, aspiration pneumonia, and pressure injury.

Abstract
BACKGROUND & AIMS This study aimed to investigate the associations of pre-existing sarcopenia with swallowing function, oral intake level, and aspiration pneumonia in patients with acute stroke. METHODS This observational study included patients (≥60 years of age) with acute ischemic stroke or intracerebral hemorrhage within 7 days of onset who were screened for sarcopenia, malnutrition, and swallowing difficulties in a stroke-care unit within 48 h of admission. Sarcopenia was defined by the Asian Working Group on Sarcopenia 2019 as having a low calf circumference, handgrip strength, and appendicular muscle mass index. The primary outcome was impaired oral intake (functional oral intake scale <5 points) at 3, 7, and 14 days after admission, and the secondary outcome was aspiration pneumonia during hospitalization. RESULTS We enrolled 350 patients (median age of 77 years; 63% males) who underwent the aforementioned screening. Sarcopenia was diagnosed in 34% of patients, and malnutrition was found in 66% of patients with sarcopenia. When compared with the comparison group (defined as patients with either or both normal calf circumference and handgrip strength), the sarcopenia group had significantly lower tongue pressure and a higher prevalence of dysphagia. Sarcopenia was associated with functional oral intake scale <5 at 7 days (adjusted odds ratio [OR], 4.72; 95% confidence interval [CI], 1.91-11.71); p = 0.002) and 14 days (adjusted OR, 3.93; 95% CI, 1.47-10.53; p = 0.006) and with aspiration pneumonia during hospitalization (adjusted OR, 6.12; 95% CI, 1.63-22.94; p = 0.007). CONCLUSION Acute stroke patients with sarcopenia may have weakness of the swallowing-related muscles which may lead to impaired oral intake and aspiration pneumonia.

Abstract
BACKGROUND Previous studies have shown reduced survival in Lewy body dementia (LBD) compared to Alzheimer's disease (AD), but the reasons for this are not known. We identified cause of death categories accounting for the reduced survival in LBD. METHODS We linked cohorts of patients with dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD) and AD, with proximal cause of death data. We examined mortality by dementia group and hazard ratios for each death category by dementia group in males and females separately. In a specific focus on the dementia group with the highest mortality rate versus reference, we examined cumulative incidence to identify the main causes of death accounting for the excess deaths. RESULTS Hazard ratios for death were higher in PDD and DLB compared to AD, for both males and females. PDD males had the highest hazard ratio for death across the dementia comparison groups (HR 2.7, 95% CI 2.2-3.3). Compared with AD, hazard ratios for "nervous system" causes of death were significantly elevated in all LBD groups. Additional significant cause-of-death categories included aspiration pneumonia, genitourinary causes, other respiratory causes, circulatory and a "symptoms and signs" category in PDD males; other respiratory causes in DLB males; mental disorders in PDD females; and aspiration pneumonia, genitourinary and other respiratory causes in DLB females. CONCLUSION Further research and cohort development is required to investigate differences by age group, to extend cohort follow-up to the whole population and to investigate the risk-balance of interventions which may differ by dementia group.

Abstract
BACKGROUND Every minute, six indigenous Africans develop new strokes. Patient-level and system-level contributors to early stroke fatality in this region are yet to be delineated. We aimed to identify and quantify the contributions of patient-level and system-level determinants of inpatient stroke fatality across 16 hospitals in Ghana and Nigeria. METHODS The Stroke Investigative Research and Educational Network (SIREN) is a multicentre study involving 16 sites in Ghana and Nigeria. Cases include adults (aged ≥18 years) with clinical and radiological evidence of an acute stroke. Data on stroke services and resources available at each study site were collected and analysed as system-level factors. A host of demographic and clinical variables of cases were analysed as patient-level factors. A mixed effect log-binomial model including both patient-level and system-level covariates was fitted. Results are presented as adjusted risk ratios (aRRs) with respective 95% CIs. FINDINGS Overall, 814 (21·8%) of the 3739 patients admitted with stroke died as inpatients: 476 (18·1%) of 2635 with ischaemic stroke and 338 (30·6%) of 1104 with intracerebral haemorrhage. The variability in the odds of stroke fatality that could be attributed to the system-level factors across study sites assessed using model intracluster correlation coefficient was substantial at 7·3% (above a 5% threshold). Stroke units were available at only five of 16 centres. The aRRs of six patient-level factors associated with stroke fatality were: low vegetable consumption, 1·19 (95% CI 1·07-1·33); systolic blood pressure, 1·02 (1·01-1·04) for each 10 mm Hg rise; stroke lesion volume more than 30 cm3, 1·48 (1·22-1·79); National Institutes of Health Stroke Scale (NIHSS) score, 1·20 (1·13-1·26) for each 5-unit rise; elevated intracranial pressure, 1·75 (1·31-2·33); and aspiration pneumonia, 1·79 (1·16-2·77). INTERPRETATION Studies are needed to assess the efficacy of interventions targeting patient-level factors such as aspiration pneumonia in reducing acute stroke fatality in this region. Policy directives to improve stroke unit access are warranted. FUNDING US National Institutes of Health.

Abstract
OBJECTIVE Oral feeding by children with bronchiolitis on high-flow nasal cannula (HFNC) is questioned, resulting in high practice variability. Our objective was to determine the incidence of aspiration pneumonia and adverse feeding events in otherwise healthy children with bronchiolitis on HFNC who fed orally from admission. METHODS We conducted a single-center, retrospective chart review, in a tertiary children's hospital, of 876 children who were <24 months old, admitted for bronchiolitis, and treated with HFNC in the pediatric ward from March 2017 to May 2020. Primary outcomes included the incidence of aspiration pneumonia and adverse feeding events. Secondary outcomes included escalation of care, frequency and duration of nil per os status, length of stay, and 7-day readmission. RESULTS Most patients (77.2%) met inclusion criteria and were fed orally within 2 hours of admission. The average maximum HFNC flow rate was 8 L/min (1 L/kg/min); the average maximum respiratory rate was 62 ± 10. Adverse feeding events occurred in 11 patients (1.6%), of which 3 had a concern for possible microaspiration. None were diagnosed with or treated for aspiration pneumonia. Few patients (8.1%) were made nil per os while on HFNC but returned to oral feeding by discharge. CONCLUSION Among those with bronchiolitis on HFNC who received oral nutrition on admission, there were few incidences of adverse feeding events and no diagnoses of aspiration pneumonia, suggesting that oral feeding while on HFNC can be well-tolerated in similar populations. However, this study was limited by its single-center retrospective design, and future prospective studies are needed.

Abstract
Biophysical insults that either reduce barrier function (COVID-19, smoke inhalation, aspiration, and inflammation) or increase mechanical stress (surfactant dysfunction) make the lung more susceptible to atelectrauma. We investigate the susceptibility and time-dependent disruption of barrier function associated with pulmonary atelectrauma of epithelial cells that occurs in acute respiratory distress syndrome (ARDS) and ventilator-induced lung injury (VILI). This in vitro study was performed using Electric Cell-substrate Impedance Sensing (ECIS) as a noninvasive evaluating technique for repetitive stress stimulus/response on monolayers of the human lung epithelial cell line NCI-H441. Atelectrauma was mimicked through recruitment/derecruitment (RD) of a semi-infinite air bubble to the fluid-occluded micro-channel. We show that a confluent monolayer with a high level of barrier function is nearly impervious to atelectrauma for hundreds of RD events. Nevertheless, barrier function is eventually diminished, and after a critical number of RD insults, the monolayer disintegrates exponentially. Confluent layers with lower initial barrier function are less resilient. These results indicate that the first line of defense from atelectrauma resides with intercellular binding. After disruption, the epithelial layer community protection is diminished and atelectrauma ensues. ECIS may provide a platform for identifying damaging stimuli, ventilation scenarios, or pharmaceuticals that can reduce susceptibility or enhance barrier-function recovery.

Abstract
Choking and aspiration pneumonia are a leading cause of preventable death for people in residential care in Australia. In Victoria, in 2018-2019, 59% of deaths of persons in residential care that were referred to the coroner were from aspiration pneumonia. In 2016-2017, in New South Wales, the leading cause of death in people with disability living in residential care was pneumonitis caused by solids and fluids in the lungs. Such deaths are closely linked with swallowing problems (dysphagia) and people with cognitive impairments and multiple health issues, including mental health issues, are most at risk. This commentary focuses on coronial inquests where coroners' findings have identified dysphagia or aspiration pneumonia as a cause of death or a contributor to a person's death. It also includes a summary of the recommendations by coroners which highlight processes that should be implemented to improve the safety of people with dysphagia.

Abstract
Background Elderly inpatients who develop fevers after resumption of oral intake are often considered to have aspiration pneumonia (AP) and be tentatively fasted. Fasting has been associated with prolonged hospital stays and decreased swallowing ability. The purpose of this study was to compare AP and other infections after resumption of oral intake in elderly inpatients and to identify the clinical characteristics. Patients and methods The records of patients who were admitted to a public tertiary hospital and referred for evaluation of swallowing disability were retrospectively reviewed to identify those who had developed AP, non-AP, or urinary tract infection (UTI) after resumption of oral intake. Eligible patients were enrolled consecutively in the study. The patient characteristics, physical findings, laboratory data, oral intake status at the time of onset of symptoms, and rate of discontinuation of oral intake after onset of infection were compared between the three types of infection. Results A total of 193 patients developed an infectious illness after resuming oral intake. Among them, 114 patients had a diagnosis of AP (n = 45), non-AP (n = 24), or UTI (n = 45). There were no significant differences in patient characteristics, physical findings or laboratory data between the group with AP and the other two groups. AP developed at a median of 6 (range 1–16) days after resumption of oral intake. The rate of discontinuation of oral intake was 91.1% in the AP group, 58.3% in the non-AP group, and 26.7% in the UTI group, respectively. Conclusion Infectious diseases other than AP should be considered in the differential diagnosis when nosocomial fever develops in elderly inpatients more than 17 days after resuming oral intake. Furthermore, nosocomial fever after resuming oral intake has many causes other than AP, and discontinuation of oral intake should be carefully considered.

Abstract
PURPOSE The presence of oropharyngeal dysphagia increases the likelihood of prandial aspiration, and aspiration increases the likelihood of a dysphagia-related pulmonary sequelae such as aspiration pneumonia, acute respiratory distress syndrome, pulmonary fibrosis, and even death. Although these outcomes are unfortunate, it is important to point out that these consequences are not solely determined by the presence of aspiration. The purpose of this tutorial is to provide current information on pulmonary defenses and the variables that increase risk of an adverse outcome in individuals who aspirate. METHOD This tutorial reviews the basics of lung defenses and summarizes the literature to make the case that the host is a central theme in dysphagia management. Case studies are employed to highlight the key variables. RESULTS Based on a literature review, a series of questions are proposed for consideration in dysphagia management. These questions, which take the focus away from the presence of aspiration and toward the associated risks within an individual, are then applied to two case studies. CONCLUSIONS A guiding framework is proposed to encourage clinicians to assess more than the presence of aspiration and consider the individual's ability to cope with the aspirated material. In the presence of aspiration, clinicians are urged to focus on the risk factors that can lead to a negative consequence, identify which factors are modifiable, and determine when a level of risk is acceptable.

Abstract
OBJECTIVES The present study aimed to investigate the incidence of and risk factors for postoperative pneumonia and aspiration pneumonia after hip fracture surgery. DESIGN Retrospective cohort study from 2005 to 2021. SETTING Asan Medical Center in Seoul, Republic of Korea. PARTICIPANTS A total 1,208 patients aged ≥ 65 years who underwent hip fracture surgery. MEASUREMENTS Postoperative pneumonia was defined as cases with new infiltration on chest x-ray or chest computed tomography (CT) after surgery or confirmed by a pulmonologist's consultation and diagnosis. Aspiration pneumonia was defined as: 1) radiologic findings of hospital-acquired pneumonia on chest radiographs or CT, medical record of aspiration pneumonia confirmed by a pulmonologist's consultation, and history of vomiting or aspiration, or 2) gravity-dependent opacity on chest CT when the history of vomiting or aspiration is ambiguous. Patient demographics, past medical history, pre-injury Koval score, Charlson Comorbidity Index (CCI), blood test results, length of hospital stay, and in-hospital mortality were evaluated. A comparison analysis and binary logistic regression were performed to identify the incidence and risk factors for postoperative pneumonia and aspiration pneumonia. RESULTS Postoperative pneumonia was diagnosed in 47 patients (3.9%), including 20 with aspiration pneumonia (1.7%). In the multivariate analysis, postoperative delirium (odds ratio [OR], 3.42; P < 0.001), American Society of Anesthesiologists (ASA) scores ≥ 3 (OR, 2.11; P = 0.021), and CCI (OR, 1.21; P = 0.013) were significant risk factors for postoperative pneumonia. Male sex (OR, 3.01; P = 0.017), postoperative delirium (OR, 3.16; P = 0.014), and preoperative serum albumin levels < 3.5 g/dL (OR, 7.00; P = 0.010) were significant risk factors for aspiration pneumonia. CONCLUSION ASA classification ≥ 3, higher CCI, and postoperative delirium were the risk factors for postoperative pneumonia. Male sex, postoperative delirium, and lower preoperative serum albumin level were the risk factors for aspiration pneumonia. Thus, physicians should pay attention to patients with the risk factors.

Abstract
OBJECTIVE To compare hospital outcomes associated with commonly used antibiotic therapies for aspiration pneumonia in children with neurologic impairment (NI). DESIGN/METHODS A retrospective study of children with NI hospitalized with aspiration pneumonia at 39 children's hospitals in the Pediatric Health Information System database. Exposure was empiric antibiotic therapy classified by antimicrobial activity. Outcomes included acute respiratory failure, intensive care unit (ICU) transfer, and hospital length of stay (LOS). Multivariable regression evaluated associations between exposure and outcomes and adjusted for confounders, including medical complexity and acute illness severity. RESULTS In the adjusted analysis, children receiving Gram-negative coverage alone had two-fold greater odds of respiratory failure (odds ratio [OR] 2.15; 95% CI: 1.41-3.27), greater odds of ICU transfer (OR 1.80; 95% CI: 1.03-3.14), and longer LOS [adjusted rate ratio (RR) 1.28; 95% CI: 1.16-1.41] than those receiving anaerobic coverage alone. Children receiving anaerobic and Gram-negative coverage had higher odds of respiratory failure (OR 1.65; 95% CI: 1.19-2.28) than those receiving anaerobic coverage alone, but ICU transfer (OR 1.15; 95% CI: 0.73-1.80) and length of stay (RR 1.07; 95% CI: 0.98-1.16) did not statistically differ. For children receiving anaerobic, Gram-negative, and P. aeruginosa coverage, LOS was shorter (RR 0.83; 95% CI: 0.76-0.90) than those receiving anaerobic coverage alone; odds of respiratory failure and ICU transfer rates did not significantly differ. CONCLUSIONS Anaerobic therapy appears to be important in the treatment of aspiration pneumonia in children with NI. While Gram-negative coverage alone was associated with worse outcomes, its addition to anaerobic therapy may not yield improved outcomes.

Abstract
A 74-year-old man with aspiration pneumonia was admitted in the internal medicine department. CT revealed progressive carcinoma of RS-Ra, which became the focus of intervention after the pneumonia was treated. After having been allowed temporary discharge, the patient was rehospitalized for surgical operation and rehabilitation. During the perioperative period of cancer patients, we use body distribution data for teaching and environment setting, which is a useful tool in rehabilitation. Rectal cancer was observed after hospitalization for pneumonia, presenting an interesting case. Therefore, care needs to be taken as body pressure distribution may be modified by comorbidity.

Abstract
IMPORTANCE Patients with alcohol use disorder (AUD) are at elevated risk of developing pneumonia, but few studies have assessed the outcomes of pneumonia in patients with AUD. OBJECTIVES To compare the causes, treatment, and outcomes of pneumonia in patients with and without AUD and to understand the associations of comorbid illnesses, alcohol withdrawal, and any residual effects due to alcohol itself with patient outcomes. DESIGN, SETTING, AND PARTICIPANTS A retrospective cohort study was conducted of 137 496 patients 18 years or older with pneumonia who were admitted to 177 US hospitals participating in the Premier Healthcare Database from July 1, 2010, to June 30, 2015. Statistical analysis was conducted from October 27, 2017, to August 20, 2018. EXPOSURE Alcohol use disorders identified from International Classification of Diseases, Ninth Revision, Clinical Modification codes. MAIN OUTCOMES AND MEASURES Pneumonia cause, antibiotic treatment, inpatient mortality, clinical deterioration, length of stay, and cost. Associations of AUD with these variables were studied using generalized linear mixed models. RESULTS Of 137 496 patients with community-acquired pneumonia (70 358 women and 67 138 men; mean [SD] age, 69.5 [16.2] years), 3.5% had an AUD. Patients with an AUD were younger than those without an AUD (median age, 58.0 vs 73.0 years; P < .001), more often male (77.3% vs 47.8%; P < .001), and more often had principal diagnoses of aspiration pneumonia (10.9% vs 9.8%; P < .001), sepsis (38.6% vs 30.7%; P < .001), or respiratory failure (9.3% vs 5.5%; P < .001). Their cultures more often grew Streptococcus pneumoniae (43.7% vs 25.5%; P < .001) and less frequently grew organisms resistant to guideline-recommended antibiotics (25.0% vs 43.7%; P < .001). Patients with an AUD were treated more often with piperacillin-tazobactam (26.2% vs 22.5%; P < .001) but equally as often with anti-methicillin-resistant Staphylococcus aureus agents (32.9% vs 31.8%; P = .11) compared with patients without AUDs. When adjusted for demographic characteristics and insurance, AUD was associated with higher mortality (odds ratio, 1.40; 95% CI, 1.25-1.56), length of stay (risk-adjusted geometric mean ratio, 1.24; 95% CI, 1.20-1.27), and costs (risk-adjusted geometric mean ratio, 1.33; 95% CI, 1.28-1.38). After additional adjustment for differences in comorbidities and risk factors for resistant organisms, AUD was no longer associated with mortality but remained associated with late mechanical ventilation (odds ratio, 1.28; 95% CI, 1.12-1.46), length of stay (risk-adjusted geometric mean ratio, 1.04; 95% CI, 1.01-1.06), and costs (risk-adjusted geometric mean ratio, 1.06; 95% CI, 1.03-1.09). Models segregating patients undergoing alcohol withdrawal showed that poorer outcomes among patients with AUD were confined to the subgroup undergoing alcohol withdrawal. CONCLUSIONS AND RELEVANCE This study suggests that, compared with hospitalized patients with community-acquired pneumonia but without AUD, those with AUD less often harbor resistant organisms. The higher age-adjusted risk of death among patients with AUD appears to be largely attributable to differences in comorbidities, whereas greater use of health care resources may be attributable to alcohol withdrawal.

Abstract
INTRODUCTION Sweet potato may contain furanoterpenoids, including ipomeamarone, which cause lung edema. CASE PRESENTATION A 10-year-old schoolgirl was hospitalized with asthma exacerbation and acute pneumonia. Chest radiographs showed a diffuse opacity of the left lung and hyperpermeability of the right lung. Computed tomography indicated foreign-body aspiration. Flexible bronchoscopy revealed an inhaled piece of sweet potato obstructing the left main bronchus. Although the patient's dyspnea worsened after removal of the sweet potato, she recovered with the treatment based on the 2014 Japanese Childhood Asthma Guidelines. CONCLUSION Cases of sweet potato aspiration need careful treatment after removal of the foreign body.

Abstract
OBJECTIVE To investigate incidence, clinical features, potential risk factors, and prognostic indicators for aspiration pneumonia in Pugs, French Bulldogs, and Bulldogs. DESIGN Retrospective, observational study. ANIMALS 41 brachycephalic dogs with aspiration pneumonia. PROCEDURES Medical records of a veterinary referral hospital were retrospectively searched to identify Pugs, French Bulldogs, and Bulldogs treated for aspiration pneumonia between 2006 and 2015. Signalment, clinical data, and outcomes were recorded. Variables of interest were analyzed for statistical associations with outcome. Incidence of aspiration pneumonia for the population of interest was compared with that for all other dog breeds and for the general hospital population of dogs during the study. RESULTS 41 of 2,141 (1.91%) dogs of the selected brachycephalic breeds and 396 of 80,137 (0.49%) dogs overall had a diagnosis of aspiration pneumonia. Relative risk of the disease in the population of interest was 3.77 times that for all other breeds. Median age at disease onset was greater for Pugs (83 months) than for French Bulldogs (8 months) and Bulldogs (6 months). History of gastrointestinal signs was the most commonly observed preidentified risk factor (27/41 [66%]) in these breeds. Neurologic disease was significantly more common in Pugs than in French Bulldogs and Bulldogs. On univariate analysis, increased age, male sex, obtundation, hypoalbuminemia, azotemia, and high liver enzyme activities were associated with nonsurvival; on logistic regression, increased age was associated with nonsurvival. CONCLUSIONS AND CLINICAL RELEVANCE Age at onset and presence of other risk factors for aspiration pneumonia may vary among brachycephalic dog breeds. Prospective studies are needed to determine common risk factors and prognostic indicators for aspiration pneumonia in the larger population of brachycephalic dogs.

Abstract
Introduction A number of video-fluoroscopic swallowing study (VFSS) abnormalities have been reported in patients with Parkinson’s disease (PD). However, the most crucial finding of subsequent aspiration pneumonia has not been validated fully. We conducted a retrospective and case-control study to determine the clinically significant VFSS findings in this population, and to propose a practical scale for predicting aspiration pneumonia in patients with PD. Methods We enrolled 184 PD patients who underwent VFSS because of suspected dysphagia. The patients who developed aspiration pneumonia within six months of the VFSS were assigned as cases and the patients without aspiration pneumonia at six months were designated as controls. Logistic regression analysis was performed to determine the prognostic VFSS features based on the data of swallowing 3 mL of jelly, which were used to make a PD VFSS scale (PDVFS). The validity of the new PDVFS was evaluated by ROC analysis. Additionally, we used the survival time analysis to compare time to death between groups, stratified by the PDVFS score. Results Twenty-five patients developed aspiration pneumonia. Among the previously-proposed VFSS features, mastication, lingual motility prior to transfer, aspiration, and total swallow time were identified as significant prognostic factors. We combined these factors to form the PDVFS. The PDVFS score ranges from 0 to 12, with 12 being the worst. ROC analysis revealed 92% sensitivity and 82% specificity at a cutoff point of 3. The higher PDVFS group showed shorter time-to-death than the lower PDVFS group (log rank P = 0.001). Conclusion Our newly developed VFSS severity scale (based on jelly swallowing) for patients with PD was easy to rate and could predict subsequent aspiration pneumonia and poor prognosis in patients with PD.

Abstract
The association between achalasia and no tuberculosis mycobacterial lung infection is well described in the literature. MycobactériumFortuitum is often responsible, and the clinical's presentation is an aspiration pneumonia resistant to usual antibiotic therapy. We report the case of a 15 year-old patient with the history of Allgrove syndrome. The chest imaging showed right lung congestion; the diagnosis was bacteriological and MycobactériumFortuitum resistant to rifampicin, isoniazid, pyrazinamide and ethambutol was isolated. The patient was treated by the association cotrimoxazole, ciprofloxacin and clarithromycin for 12 months and the clinical, radiological and bacteriological outcomes were favorable. To prevent the recurrence the patient benefited from a cardiomyotomy.

Abstract
The purpose of this investigation was to investigate the association between first attempt success and intubation-related complications in the Intensive Care Unit after the widespread adoption of video laryngoscopy. We further sought to characterize and identify the predictors of complications that occur despite first attempt success. This was a prospective observational study of consecutive intubations performed with video laryngoscopy at an academic medical Intensive Care Unit. Operator, procedural, and complication data were collected. Multivariable logistic regression was used to examine the relationship between the intubation attempts and the occurrence of one or more complications. A total of 905 patients were intubated using a video laryngoscope. First attempt success occurred in 739 (81.7 %), whereas >1 attempt was needed in 166 (18.3 %). One or more complications occurred in 146 (19.8 %) of those intubated on the first attempt versus 107 (64.5 %, p < 0.001) of those requiring more than one attempt. Logistic regression analysis shows that >1 attempt is associated with 6.4 (95 % CI 4.4-9.3) times the adjusted odds of at least one complication. Pre-intubation predictors of at least one complication despite first attempt success include vomit or edema in the airway as well as the presence of hypoxemia or hypotension. There are increased odds of complications with even a second attempt at intubation in the Intensive Care Unit. Complications occur frequently despite a successful first attempt, and as such, the goal of airway management should not be simply first attempt success, but instead first attempt success without complications.

Abstract
An 89-year-old woman was admitted to our hospital with vomiting, abdominal distension, and anorexia.A CT scan revealed an enhanced thickening lesion on the wall of the ascending colon, and intestinal expansion from the small intestine to the caecum.On colon fibroscopy, a round tumor was observed adjacent to the oral side of the hepatic flexure even though the end of the microscope could not progress toward the deeper regions.As the obstructive colon cancer was complicated by the presence of aspiration pneumonia, surgery could not be performed under general anesthesia.We initiated curative therapy for aspiration pneumonia right at the onset.Subsequently, due to lack of improvement in the patient's general condition, we conducted a right hemicolectomy under combined epidural-spinal anesthesia.

To study the therapeutic effect of neuromuscular electrical stimulation and electromyographic biofeedback (EMG-biofeedback) therapy in improving swallowing function of Alzheimer's disease patients with dysphagia.A series of 103 Alzheimer's disease patients with dysphagia were divided into 2 groups, among which the control group (n = 50) received swallowing function training and the treatment group (n = 53) received neuromuscular electrical stimulation plus EMG-biofeedback therapy. The mini-mental state scale score was performed in all patients along the treatment period. Twelve weeks after the treatment, the swallowing function was assessed by the water swallow test. The nutritional status was evaluated by Mini Nutritional Assessment (MNA) as well as the levels of hemoglobin and serum albumin. The frequency and course of aspiration pneumonia were also recorded.No significant difference on mini-mental state scale score was noted between 2 groups. More improvement of swallowing function, better nutritional status, and less frequency and shorter course of aspiration pneumonia were presented in treatment group when compared with the control group.Neuromuscular electrical stimulation and EMG-biofeedback treatment can improve swallowing function in patients with Alzheimer's disease and significantly reduce the incidence of adverse outcomes. Thus, they should be promoted in clinical practice.

Abstract
BACKGROUND Intrinsic brainstem epidermoid cysts are rare, benign, slow-growing lesions. Their eloquence precludes complete excision; however, subtotal resection often will result in prolonged or sometimes permanent relief of presenting symptoms and signs. We describe an unusual case and review the literature of this pathology in the pediatric population. CASE DESCRIPTION We report an intra-axial pontine epidermoid cyst in a 2-year-old girl who presented with developmental delay, multiple cranial nerve palsies, and pneumonia. Magnetic resonance imaging demonstrated an intrinsic pontine lesion with partial restricted diffusion and an enhancing plaque, the latter not typically seen in congenital lesions like epidermoid. However, gross surgical inspection and histopathology confirmed an epidermoid. CONCLUSIONS Our case, supported by the literature, shows that brain stem epidermoid cysts may have atypical radiologic characteristics and that near-total resection remains safe and can improve outcome.

Abstract
Swallowing dysfunction caused by stroke is a risk factor for aspiration pneumonia. Tongue pressure measurement is a simple and noninvasive method for evaluating swallowing dysfunction. We have hypothesized that low tongue pressure may be able to predict pneumonia occurrence in acute stroke patients. Tongue pressure was measured using balloon-type equipment in 220 acute stroke patients. The modified Mann Assessment of Swallowing Ability (MASA) score was evaluated independently on the same day. Tongue pressure was measured every week thereafter. An improvement in tongue pressure was observed within the first 2 weeks. Receiver operating curve analysis was performed to determine the ability of tongue pressure to predict modified MASA score <95, which suggests swallowing dysfunction. The optimal cutoff for tongue pressure was 21.6 kPa (χ2 = 45.82, p<0.001, sensitivity 95.9%, specificity 91.8%, area under the curve = 0.97). The tongue pressure was significantly lower in patients with pneumonia than in those without pneumonia. Using a Cox proportional hazard model for pneumonia onset with a cutoff tongue pressure value of 21.6 kPa and adjustment for age, sex, and National Institutes of Health Stroke Scale score at admission, the tongue pressure had additional predictive power for pneumonia onset (hazard ratio, 7.95; 95% confidence interval, 2.09 to 52.11; p = 0.0013). In the group with low tongue pressure, 27 of 95 patients showed improvement of tongue pressure within 2 weeks. Pneumonia occurred frequently in patients without improvement of tongue pressure, but not in patients with improvement (31/68 and 2/27, p<0.001). Tongue pressure is a sensitive indicator for predicting pneumonia occurrence in acute stroke patients.

Abstract
Background To evaluate the association between the premotor symptoms and the prognosis of PD. Methods A total of 1213 patients who were diagnosed of PD from January 2001 to December 2008 were selected from the Taiwan’s National Health Insurance Research Database. Patients were traced back to determine the presence of premotor symptoms, including rapid eye movement sleep behavior disorder (RBD), depression, and constipation. Cox’s regression analysis was used to detect the risks between the occurrence of premotor symptoms and the outcome (including death, psychosis, accidental injury, dementia and aspiration pneumonia). In addition, the association between premotor symptoms and levodopa equivalent dosage (LED) was examined. Results Higher occurrence of death, dementia and aspiration pneumonia were identified in PD patients with premotor symptoms than without premotor symptoms (HR 1·69, 95% CI 1·34–2·14, p <0·001 for death; HR 1·63, 95% CI 1·20–2·22, p = 0·002 for dementia; HR 2·45, 95% CI 1·42–4·21, p = 0·001 for aspiration pneumonia). In a comorbidities-stratified analysis, PD patients with premotor symptoms showed significantly high risks of mortality and morbidity (dementia and aspiration pneumonia), especially in the absence of comorbidities. Independent predictors of mortality in PD were found to be higher age, male sex, constipation, RBD, RBD with constipation and depression, and diabetes. Furthermore, no significant differences of LED and subsequent accidental injury were noted between PD patient with or without premotor symptoms. Conclusion Premotor symptoms seem to be not merely risk factors, but also prognostic factors of PD.

Abstract
A 5-month-old female pit bull terrier dog evaluated for ataxia, progressive regurgitation, and recurrent aspiration pneumonia had markedly elevated creatine kinase activity, non-inflammatory generalized myopathy, and severe esophageal dysmotility. A narrow-field total laryngectomy was performed. The dog is doing well 30 months after surgery, and no longer has episodes of aspiration pneumonia, despite intermittent regurgitation. This case represents the first application of total laryngectomy for the prevention of chronic recurrent aspiration pneumonia in the dog.

Abstract
Dysphagia occurs in acute stroke patients at high rates, and many of them develop aspiration pneumonia. Team approaches with the cooperation of various professionals have the power to improve the quality of medical care, utilizing the specialized knowledge and skills of each professional. In our hospital, a multidisciplinary participatory swallowing team was organized. The aim of this study was to clarify the influence of a team approach on dysphagia by comparing the rates of pneumonia in acute stroke patients prior to and post team organization. All consecutive acute stroke patients who were admitted to our hospital between April 2009 and March 2014 were registered. We analyzed the difference in the rate of pneumonia onset between the periods before team organization (prior period) and after team organization (post period). Univariate and multivariate analyses were performed using a Cox proportional hazards model to determine the predictors of pneumonia. We recruited 132 acute stroke patients from the prior period and 173 patients from the post period. Pneumonia onset was less frequent in the post period compared with the prior period (6.9% vs. 15.9%, respectively; p = 0.01). Based on a multivariate analysis using a Cox proportional hazards model, it was determined that a swallowing team approach was related to pneumonia onset independent from the National Institutes of Health Stroke Scale score on admission (adjusted hazard ratio 0.41, 95% confidence interval 0.19-0.84, p = 0.02). The multidisciplinary participatory swallowing team effectively decreased the pneumonia onset in acute stroke patients.

Abstract
Aspiration is well recognized as a cause of pulmonary disease and is not uncommon in patients with altered consciousness.The mortality rate of aspiration pneumonia is approximately 1% in outpatient setting and upto 25% in those requiring hospitalization. This study was done to see the pattern of pulmonary involvement and outcome of aspiration pneumonia in patients with altered consciousness admitted in medicine department of a tertiary care hospital in our country. This was a prospective observational study conducted among the 52 adult patients of aspiration pneumonia with altered consciousness admitted in the medicine department of Dhaka Medical College Hospital (DMCH), during June 2010 to December 2010. Aspiration pneumonia was confirmed by clinical examination and laboratory investigations. Hematologic measurements (TC of WBC, Hb%, ESR, platelet count), chest X-ray, blood gas analysis, blood urea, creatinine and random blood sugar, sputum for Gram staining, sputum for culture sensitivity and blood culture were done in all patients.Assessment of altered conscious patient was done by application of the Glasgow Coma Scale. Case record forms with appropriate questionnaire were filled for all patients. The mean±SD age was 57.42±13.63 years with ranged from 25 to 90 years. Out of 52 patients, 37(71.15%) patients were male and 15(28.85%) patients were female. Following aspiration 76.92% patients developed pneumonitis, 13.46% patients developed lung abscess and only 9.62% patients developed ARDS. Most (33) of the patients had opacity in right lower zone and 13 patients had opacity in the left lower zone, 6 patients had opacity in right mid zone. Only 10 patients had opacity in both lower zones. In this study overall mortality rate was 23%. If only one lobe was involved radiologically, mortality was 8.33%. If two or more lobes on one or both sides were involved, mortality was in the range of 25-91%.

Abstract
Hepatocellular carcinoma with colonic metastasis is rare. It mainly occurs by direct invasion and presents with bloody stools. We describe a patient with haematogenous metastasis to the rectum who presented with tenesmus. To our knowledge, such an association has not been reported previously. Colonic metastasis should be considered when patients with hepatocellular carcinoma present with bloody stools or tenesmus.

Abstract
Impaired visualization during intubation due to vomitus of gastric contents is a potential cause of failed intubation. An 82-year-old woman was intubated emergently for respiratory distress secondary to aspiration of gastric contents. Her intubation was hindered by the presence of a massive amount of ongoing vomitus that impaired visualization and overwhelmed all suction capabilities. Intentional blind intubation of the esophagus with an endotracheal tube was performed with successful diversion of ongoing vomitus away from the airway. Thereafter, after brief suctioning, the larynx was quickly visualized and the patient was successfully intubated.

Abstract
Aspiration pneumonia is a frequent cause of morbidity and mortality in children with neurological deficits. We present the case of a 4-month-old infant from the Foster Care Center, with severe psychomotor retardation, blindness, and associated cardiac malformation, who was admitted to the Pediatrics Clinic of the Emergency County Hospital of Craiova, Romania, presenting aspiration pneumonia and moderate respiratory insufficiency. Under sustained, early instituted treatment, the evolution was towards death. The chest radiography and histopathological examination of the pulmonary tissue confirmed the diagnosis. The neurological impairment was not only a favoring factor for aspiration, through the deglutition disorders, but it was also an aggravating one, through the bacterial colonization of the lungs.

Abstract
Inadequate ventilator settings may cause overwhelming inflammatory responses associated with ventilator-induced lung injury (VILI) in patients with acute respiratory distress syndrome (ARDS). Here, we examined potential benefits of glutamine (GLN) on a two-hit model for VILI after acid aspiration-induced lung injury in rats. Rats were intratracheally challenged with hydrochloric acid as a first hit to induce lung inflammation, then randomly received intravenous GLN or lactated Ringer's solution (vehicle control) thirty min before different ventilator strategies. Rats were then randomized to receive mechanical ventilation as a second hit with a high tidal volume (TV) of 15 mL/kg and zero positive end-expiratory pressure (PEEP) or a low TV of 6 mL/kg with PEEP of 5 cm H2O. We evaluated lung oxygenation, inflammation, mechanics, and histology. After ventilator use for 4 h, high TV resulted in greater lung injury physiologic and biologic indices. Compared with vehicle treated rats, GLN administration attenuated lung injury, with improved oxygenation and static compliance, and decreased respiratory elastance, lung edema, extended lung destruction (lung injury scores and lung histology), neutrophil recruitment in the lung, and cytokine production. Thus, GLN administration improved the physiologic and biologic profiles of this experimental model of VILI based on the two-hit theory.

Abstract
A 77-year-old man with a history of pulmonary sarcoidosis was referred with persistent cough and reduced air entry on auscultation of the right lung base. He was an ex-smoker with a 40-pack-year history and his general practitioner was concerned about the possibility of bronchogenic carcinoma. A chest radiograph showed a right-sided pleural effusion with right mid-zone airspace opacification. Bronchoscopy revealed a peanut covered in mucus lodged in the right lower lobe bronchus. CT of the thorax demonstrated a multiloculated right pleural effusion with associated compressive atelectasis, consistent with chronic empyema. A chest drain was inserted but failed to fully clear the collection and the patient proceeded to a thoracoscopic decortication of a pleural empyema secondary to the right lower lobe obstruction from an inhaled peanut. His postoperative recovery was uncomplicated.

Abstract
The purpose of this review is to assess the current state of the literature on the topic of deep brain stimulation (DBS) and its effects on swallowing function in Parkinson's disease (PD). Pubmed, Cochrane review, and web of science searches were completed on all articles addressing DBS that contained a swallowing outcome measure. Outcome measures included the penetration/aspiration scale, pharyngeal transit time, oropharyngeal residue, drooling, aspiration pneumonia, death, hyolaryngeal excursion, epiglottic inversion, UPDRS scores, and presence of coughing/throat clearing during meals. The search identified 13 studies specifically addressing the effects of DBS on swallowing. Critical assessment of the 13 identified peer-reviewed publications revealed nine studies employing an experimental design, (e.g. "on" vs. "off", pre- vs. post-DBS) and four case reports. None of the nine experimental studies were found to identify clinically significant improvement or decline in swallowing function with DBS. Despite these findings, several common threads were identified across experimental studies and will be examined in this review. Additionally, available data demonstrate that, although subthalamic nucleus (STN) stimulation has been considered to cause more impairment to swallowing function than globus pallidus internus (GPi) stimulation, there are no experimental studies directly comparing swallowing function in STN vs. GPi. Moreover, there has been no comparison of unilateral vs. bilateral DBS surgery and the coincident effects on swallowing function. This review includes a critical analysis of all experimental studies and discusses methodological issues that should be addressed in future studies.

Abstract
The University of Mississippi Medical Center (UMMC) has become a center for ECMO (Extracorporeal Membrane Oxygenation), providing this service to patients requiring this life-saving modality. UMMC is the only ECMO center in the state. Prior to the cases presented, ECMO use at UMMC has been limited to neonates and the pediatric patient population as well as by the cardiothoracic service for patients with cardiac failure or inability to wean from bypass. The use of ECMO for non-cardiac support in the adult population has been limited in the past, but recent reports in the literature and experience elsewhere has proven the viability of the technology. This is a retrospective report of the first three adult non-cardiac cases employing ECMO for ARDS (Adult Respiratory Distress Syndrome) in Mississippi. We achieved 100% survival in a disease process which reportedly carries a mortality ranging from 20-50%. A brief review of ECMO and its use in this population is also presented.

Abstract
Aspiration pneumonia and aspiration pneumonitis are associated with significant morbidity in veterinary and human medicine. A variety of medical conditions and medications can predispose patients to aspiration, and every precaution should be taken to prevent aspiration from occurring. For dogs that aspirate oral or gastric contents and subsequently develop pneumonia, monitoring and supportive care are imperative. This article discusses the pathophysiology, prevention, and diagnosis of aspiration pneumonia.

Abstract
INTRODUCTION Angiotensin-converting enzyme inhibitors (ACEIs) are reported to reduce the incidence of aspiration pneumonia in hypertensive patients. In this study, a metaanalysis was conducted to obtain statistically more reliable estimates of outcome. METHODS The MEDLINE and JMEDICINE databases were searched and the following study selection criteria were applied: (1) comparative controlled studies identified with the following keywords: drug therapy, ACEI, hypertension, swallowing function, dysphagia, stroke, and pneumonia; (2) a minimum follow-up period of 6 months; and (3) a minimum number of patients of more than 100. Patients with hypertension and a history of stroke or transient ischemic attack (TIA) in five controlled studies that reported the incidence of pneumonia were included in the analysis. RESULTS A total of 8,693 post-stroke patients were given ACEIs with another antihypertensive agent or placebo as a control. In all studies, ACEIs, particularly imidapril, exhibited preventive effects equating to a relative risk that ranged from 0.32 to 0.81 compared with controls. In the combined studies the overall relative risk of ACEI-treated patients versus controls was 0.61 (95% confidence intervals [CI] 0.51-0.75; P < 0.001). Among Asian patients, the relative risk was 0.42 (95% CI 0.32-0.56; P < 0.001). Among Japanese patients, an even greater preventive effect was found for ACEIs versus other antihypertensives (relative risk: 0.38 [95% CI 0.27-0.54; P < 0.001]). CONCLUSION ACEIs appear to be more effective than other antihypertensive agents or placebo in reducing pneumonia risk in post-stroke patients, especially in Asian populations.
