Respiratory symptoms due to a twisted nasogastric tube: A case report.

Insertion of a nasogastric tube (NGT) is generally considered safe; however, it is not without risk, and in cases of misplacement, complications and even death may occur. In this article, we reported a case of NGT misplacement in a 75-year-old male, which resulted in aspiration pneumonia. We also reviewed published cases of NGT misplacement. Clinicians should pay enough attention to the confirmation of the proper placement of an NGT. A systematic approach for NGT insertion and confirmation is required to prevent misplacement.

Safety profile of hypnotics or sedatives on community-dwelling older adults aged 75 or older in Japan: A retrospective propensity-matched cohort study.

OBJECTIVE: The purpose of the study is to assess if daily use of hypnotics increases mortality, aspiration pneumonia and hip fracture among relatively healthy individuals aged 75 years or older who lead independent lives in the community. METHOD AND PATIENTS: Of the adults aged 75 years or older residing in Hokkaido prefecture of Japan (n = 705,538), those who did not meet several exclusion criteria were eligible for generating propensity score-matched cohorts (n = 214,723). Exclusion criteria included co-prescribed medications acting on the central nervous system, diagnoses of malignant neoplasm, dementia, depression, etc. We compared 33,095 participants who were prescribed hypnotics for daily use (hypnotic group) with a propensity score-matched cohort without a prescription (control group). Participants were followed for more than 42 months. RESULTS: During the 42-month follow-up period, the incidence of the three outcome measures in the hypnotics group was significantly higher than that in the control group (aspiration pneumonia p < 0.001, hip fracture p = 0.007, and all-cause mortality p < 0.001). Sensitivity analyses utilizing inverse probability weighting demonstrated hazard ratios of 1.083 [1.023-1.146] for mortality, 1.117 [1.014-1.230] for aspiration pneumonia, and 1.720 [1.559-1.897] for hip fracture. Meanwhile, the attribute risk differences were 2.7, 1.5, and 1.0 per 1000 patient-years, respectively. CONCLUSIONS: Although daily use of hypnotics increased the risk of three events, their attribute risk differences were fewer than 3.0 per 1000 patient-years. The results will help provide guidance on whether it is reasonable to prescribe hypnotics to geriatric population aged 75 or older leading independent lives in the community.

Incidence and characteristics of aspiration pneumonia in the Nagasaki Prefecture from 2005 to 2019.

BACKGROUND: Aspiration pneumoniae remains a major health concern, particularly in the older population and has poor prognosis; however, the concept itself remains vague worldwide. This study aimed to determine the actual situation and characteristics of aspiration pneumonia from 2005 to 2019 in Nagasaki Prefecture, Japan. METHODS: Cases of aspiration pneumonia that occurred in the Nagasaki Prefecture between 2005 and 2019 were analyzed using emergency transportation records. The number of occurrences and incidence were analyzed according to age, sex, month, day of the week, and recognition time to clarify the actual situation of aspiration pneumonia. RESULTS: The total number of new aspiration pneumonia cases was 8,321, and the mean age of the patients was 83.0 years. Annual incidence per 100,000 population increased from 12.4 in 2005 to 65.1 in 2019, with the most prominent increase in the ≥ 80-year-old stratum. Males (55.1%) were more commonly affected than females (44.9%), and 82.2% of the cases involved patients aged ≥ 70 years. No significant correlations were observed between the incidence of aspiration pneumonia and season, month, or day of the week. Aspiration pneumonia occurred frequently in houses (39.8%) and facilities for elderly individuals (40.8%). At 7 days after admission, 80.9% of patients were still hospitalized and 6.5% had died. CONCLUSIONS: The incidence of aspiration pneumonia with risks of severity and mortality is increasing among elderly individuals. Valid preventive measures are urgently needed based on the findings that the disease occurs in both household and elderly care facility settings, regardless of the season.

Lack of Physician-Dentist Collaboration in Aspiration Pneumonia Prevention.

This opinion paper addresses the challenges and future directions for preventing aspiration pneumonia in Japan's rapidly aging population. It highlights the increasing proportion of elderly individuals and the associated rise in health issues like decreased swallowing function, a risk factor for aspiration pneumonia. The paper emphasizes the effectiveness of dentist-provided oral care in preventing this condition but notes the lack of collaboration between dentists and physicians in Japan's clinical practice. Key challenges identified include the scarcity of full-time hospital dentists, insufficient communication between physicians and dentists, limited patient understanding and motivation regarding oral care, and a lack of training in geriatric dentistry. The paper advocates for enhanced awareness among healthcare professionals and patients, increased hospital dentists, and improved collaboration mechanisms, particularly in light of recent positive changes in insurance reimbursement policies for elderly oral care.

Investigation of predictors for in-hospital death or long-term hospitalization in community-acquired pneumonia with risk factors for aspiration.

Background: It is known that the mortality of pneumonia in patients with risk factors for aspiration is worse than that in those without these risk factors. However, it is still unknown which risk factors for aspiration predict prognosis. Therefore, we aimed to determine which risk factors for aspiration are associated with death or prolonged hospitalization. Methods: We prospectively followed patients with community-acquired pneumonia at a single hospital providing acute to chronic care in Japan until they died or were discharged. Patients at any risk of aspiration were included. The associations between pneumonia severity, individual risk factors for aspiration, and in-hospital death or prolonged hospitalization were investigated. Overall survival was estimated by the Kaplan - Meier method, and the factors associated with in-hospital death or prolonged hospitalization were investigated by multivariate analysis using factors selected by a stepwise method. Results: In total, 765 patients with pneumonia and risk factors for aspiration were recruited. One hundred and ten patients deceased, and 259 patients were hospitalized over 27 days. In-hospital death increased as the number of risk factors for aspiration increased. In the multivariate analysis, male, impaired consciousness, acidemia, elevated blood urea nitrogen, and bedridden status before the onset of pneumonia were associated with in-hospital death (odds ratio [OR]: 2.5, 2.5, 3.6, 3.1, and 2.6; 95% confidence interval [CI]: 1.6-4.1, 1.4-4.2, 1.6-8.0, 1.9-5.0, and 1.6-4.2 respectively). In the Cox regression analysis, these factors were also associated with in-hospital death. None of the vital signs at admission were associated. Tachycardia, elevated blood urea nitrogen, hyponatremia, and bedridden status were associated with hospitalization for >27 days (OR: 4.1, 2.3, 4.3, and 2.9; 95% CI: 1.3-12.9, 1.5-3.4, 2.0-9.4, and 2.0-4.0, respectively). Conclusions: Blood sampling findings and bedridden status are useful for predicting in-hospital mortality and long-term hospitalization in patients with pneumonia and any risk factor for aspiration.

Measuring the prevalence of aspiration pneumonia in view of improving the relevance of antibiotic prescription of antibiotics: A retrospective, observational study.

PURPOSE: Aspiration pneumonia (AP) has significant incidence and impact on mortality. However, data about clinical diagnosis criteria are scarce. We aimed to evaluate according to predefined criteria the prevalence of true AP and its impact on antibiotic stewardship. METHODS: Retrospective study of patients whose main diagnosis was AP hospitalized at Amiens University Hospital in 2018. We first defined diagnostic criteria of certainty for pneumonia and aspiration. AP was then classified according to degree of certainty. RESULTS: Among 862 cases of AP, its diagnosis was certain, likely, probably in excess, certainly in excess or absent in 2 % (n = 17), 3 % (n = 26), 50.5 % (n = 433), 23.1 % (n = 198) and 21.4 % (n = 183) respectively. Irrelevant use of amoxicillin-clavulanic acid and metronidazole was found in 27 % and 13 % of cases, respectively. CONCLUSIONS: The diagnosis of AP is frequently excessive, and diagnostic tools are urgently needed to improve antibiotic stewardship.

An Aspirated Tooth Masquerading As Lung Cancer: A Unique Case Report.

Tooth aspiration, while commonly linked to predisposing conditions such as loose teeth, facial surgeries, or injuries, can also affect patients without apparent risk factors. Such small foreign body aspirations may go undiagnosed for many months as patients often tolerate the symptoms, such as chronic cough. However, the protracted course of unaddressed foreign body aspiration has the potential to resemble symptoms of malignancy, including persistent hemoptysis, weight loss, and fatigue. In this report, we detail the case of a 51-year-old man with underlying chronic obstructive pulmonary disease (COPD) whose history and symptoms initially suggested lung carcinoma. Further investigation uncovered an aspirated tooth as the culprit. The sequelae of pulmonary complications arising from endobronchial obstruction, such as post-obstructive pneumonia and atelectasis, as demonstrated in our case, further emphasize the importance of prompt detection and management of tooth aspiration.

Pediatric Dysphagia.

Pediatric dysphagia is a common condition encountered in clinical practice. We review the physiology and development of swallow, presentation, epidemiology, and etiology of dysphagia. Additionally, comorbidities, associated conditions, and medical management of dysphagia are discussed.

Impact of Antibiotics Used for Acute Aspiration Bronchitis on the Prevention of Pneumonia.

BACKGROUNDS: It remains unclear if antibiotics should be used for the treatment of acute aspiration bronchitis to prevent the development of pneumonia. This study aimed to assess the associations between the use of antibiotics and the development of pneumonia among patients with acute aspiration bronchitis. METHODS: We retrospectively reviewed consecutive patients with acute aspiration bronchitis aged ≥75 years. Acute aspiration bronchitis was defined as a condition with aspiration risk, high fever (body temperature, ≥37.5 °C), respiratory symptoms, and the absence of evidence of pneumonia. RESULTS: There was no significant difference in the incidence of pneumonia between patients treated with and without antibiotics for acute aspiration bronchitis (6/44, 14% vs. 31/143, 22%; p = 0.242). Lower estimated glomerular filtration rate (adjusted odds ratio, 0.956; 95% confidence interval, 0.920-0.993) was significantly associated with the development of pneumonia. CONCLUSIONS: Antibiotic administration should not be routinely recommended to prevent pneumonia following acute aspiration bronchitis, and patients with decreased renal function should be closely monitored. A randomized controlled trial is necessary to validate these results.

Complications of oropharyngeal dysphagia in older individuals and patients with neurological disorders: insights from Mataró hospital, Catalonia, Spain.

Background: Oropharyngeal dysphagia (OD) significantly impacts older individuals and neurologically compromised patients, hindering safe ingestion of food and liquids. Despite its prevalence, OD remains underdiagnosed and undertreated, leading to severe complications such as malnutrition, dehydration, respiratory infections, and aspiration pneumonia (AP), and increases hospital readmissions. Objectives: This study analyzes the intricate relationship between OD and various clinical complications in older individuals and patients with neurological disorders. Methods: Utilizing retrospective analysis and narrative review, our work consolidates findings from prior studies on Hospital de Mataro's dysphagia patient cohort. Revisiting OD's intricate association with clinical complications, it presents data via odds ratios (OR), incidence ratios (IR), and hazard ratios (HR) from univariate and multivariate analyses. Results: Five studies (2001-2014) involving 3,328 patients were scrutinized. OD exhibited independent and significant associations with various complications among older patients. Older individuals with OD faced heightened 1-month (ODDS 3.28) and 1-year (OR 3.42) mortality risks post-pneumonia diagnosis. OD correlated with a 2.72-fold risk of malnutrition, 2.39-fold risk of lower respiratory tract infections, 1.82-fold pneumonia readmissions (IR), and 5.07-fold AP readmissions (IR). Post-stroke OD is linked to neurological impairment (OR 3.38) and respiratory (OR 9.54) and urinary infections (OR 7.77), alongside extended hospital stays (beta coefficient 2.11). Conclusion: Oropharyngeal dysphagia causes and significantly exacerbates diverse clinical complications in older and post-stroke patients, emphasizing the urgent need for proactive identification, comprehensive assessment, and tailored management. Acknowledging OD's broader implications in general medical practice is pivotal to improving patient outcomes and healthcare quality.

Effectiveness of Drip Infusion of Lascufloxacin, a Novel Fluoroquinolone Antibiotic, for Patients with Pneumonia Including Chronic Lung Disease Exacerbations and Lung Abscesses.

Background: Lascufloxacin (LSFX), a novel fluoroquinolone antibacterial agent, has recently been used as a drip infusion for treating pneumonia, apparently with good effectiveness against various bacteria, including anaerobes, and good intrapulmonary penetration. Methods: The clinical effectiveness of LSFX was retrospectively investigated for the 55 patients admitted to our hospital with pneumonia, including chronic lung disease exacerbations and lung abscesses, from May 2021 to July 2023. Results: The median age of the 55 patients was 76.1 (34.1-93.1) years, 45 (81.8%) were male, and 48 (87.5%) patients had underlying disease. Community-acquired pneumonia was seen in 47 (85.5%) patients, including 9 (16.4%) with lung abscess, and the other 8 (14.5%) had nursing and healthcare-associated pneumonia/hospital-acquired pneumonia. Moderate pneumonia was present in 33 (61.8%) of 55 patients, and LSFX was used as a second-line treatment for 28 (50.9%) patients in whom first-line antibiotics were ineffective. The median duration of intravenous LSFX administration was 9 (2.0-49) days. Streptococcus pneumoniae and methicillin-susceptible Staphylococcus aureus were isolated from 3 (7.1%) and 2 (4.8%) patients, respectively. Of the 55 patients, 45 (81.5%) improved clinically with intravenous LSFX administration; 20 (95.2%) of 21 community-acquired pneumonia cases, including 9 (100.0%) of 9 bacterial pneumonia cases, were improved by LSFX as first-line treatment, and 8 (88.9%) of 9 lung abscess patients also showed clinical improvement with LSFX as a second-line treatment. There were no severe adverse effects in any of the 55 patients. Conclusion: Based on these data, intravenous administration of LSFX seems effective for bacterial pneumonia, including chronic lung disease exacerbations and lung abscesses, and it appears to have broad antimicrobial activity and good tissue penetration into the lung.

Should We Stop Glucagon-Like Peptide-1 Receptor Agonists Before Surgical or Endoscopic Procedures? Balancing Limited Evidence With Clinical Judgment.

The American Society of Anesthesiologists (ASA) Task Force recently recommended discontinuing glucagon-like peptide-1 receptor agonist (GLP-1 RA) agents before surgery because of the potential risk of pulmonary aspiration. However, there is limited scientific evidence to support this recommendation, and holding GLP-1 RA treatment may worsen glycemic control in patients with diabetes. As we await further safety data to manage GLP-1 RA in the perioperative period, we suggest an alternative multidisciplinary approach to manage patients undergoing elective surgery. Well-conducted observational and prospective studies are needed to determine the risk of pulmonary aspiration in persons receiving GLP-1 RA for the treatment of diabetes and obesity, as well as the short-term impact of discontinuing GLP-1 RA on glycemic control before elective procedures in persons with diabetes.

Anaerobic Antibiotic Coverage in Aspiration Pneumonia and the Associated Benefits and Harms: A Retrospective Cohort Study.

BACKGROUND: Antibiotics with extended anaerobic coverage are used commonly to treat aspiration pneumonia, which is not recommended by current guidelines. RESEARCH QUESTION: In patients admitted to hospital for community-acquired aspiration pneumonia, does a difference exist between antibiotic therapy with limited anaerobic coverage (LAC) vs antibiotic therapy with extended anaerobic coverage (EAC) in terms of in-hospital mortality and risk of Clostridioides difficile colitis? STUDY DESIGN AND METHODS: We conducted a multicenter retrospective cohort study across 18 hospitals in Ontario, Canada, from January 1, 2015, to January 1, 2022. Patients were included if the physician diagnosed aspiration pneumonia and prescribed guideline-concordant first-line community-acquired pneumonia parenteral antibiotic therapy to the patient within 48 h of admission. Patients then were categorized into the LAC group if they received ceftriaxone, cefotaxime, or levofloxacin. Patients were categorized into the EAC group if they received amoxicillin-clavulanate, moxifloxacin, or any of ceftriaxone, cefotaxime, or levofloxacin in combination with clindamycin or metronidazole. The primary outcome was all-cause in-hospital mortality. Secondary outcomes included incident C difficile colitis occurring after admission. Overlap weighting of propensity scores was used to balance baseline prognostic factors. RESULTS: The LAC and EAC groups included 2,683 and 1,316 patients, respectively. In hospital, 814 patients (30.3%) and 422 patients (32.1%) in the LAC and EAC groups died, respectively. C difficile colitis occurred in 5 or fewer patients (≤ 0.2%) and 11 to 15 patients (0.8%-1.1%) in the LAC and EAC groups, respectively. After overlap weighting of propensity scores, the adjusted risk difference of EAC minus LAC was 1.6% (95% CI, -1.7% to 4.9%) for in-hospital mortality and 1.0% (95% CI, 0.3%-1.7%) for C difficile colitis. INTERPRETATION: Extended anaerobic coverage likely is unnecessary in aspiration pneumonia because it is associated with no additional mortality benefit, only an increased risk of C difficile colitis.

Navigating Complexity: A Rare Case of Down Syndrome With Dural Venous Thrombosis in a Neonate.

This case report presents a unique clinical scenario of a 2 kg male neonate with Down syndrome complicated by dural venous thrombosis. Born via normal vaginal delivery, the infant exhibited syndromic features characteristic of Down syndrome, necessitating admission to the neonatal intensive care unit (NICU) for respiratory distress. Confirmatory karyotyping established the diagnosis. Subsequent complications included germinal matrix haemorrhage, hypoxic-ischemic encephalopathy, and aspiration pneumonia. An MRI revealed dural venous thrombosis in the left transverse sinus, an uncommon manifestation in neonates with Down syndrome. Multidisciplinary management involved respiratory support, antibiotic therapy, and neurophysiotherapy. Infectious complications, including Klebsiella pneumoniae growth, required tailored antibiotic intervention. Despite intubation and CO2 retention challenges, the neonate improved and was ultimately discharged with favourable anthropometric measurements. This case underscores the importance of a comprehensive approach to neonatal care in the context of Down syndrome, emphasising the need for early recognition and management of rare complications such as venous thrombosis. The positive outcome highlights the efficacy of a multidisciplinary strategy in addressing complex neonatal conditions.

Prognostic factors of poor outcomes in pneumonia in older adults: aspiration or frailty?

PURPOSE: Little is known about the long-term and functional prognoses of older adults with pneumonia, which complicates their management. There is a common belief that aspiration is a poor prognostic factor; however, the diagnosis of aspiration pneumonia (AP) lacks consensus criteria and is mainly based on clinical characteristics typical of the frailty syndrome. Therefore, the poor prognosis of AP may also be a result of frailty rather than aspiration. This study investigated the impact of AP and other prognostic factors in older patients with pneumonia. METHODS: We performed a retrospective cohort study of patients aged 75 years and older, admitted with pneumonia in 2021. We divided patients according to their initial diagnosis (AP or non-AP), compared outcomes using Kaplan-Meier curves, and used logistic regression to identify independent prognostic factors. RESULTS: 803 patients were included, with a median age of 84 years and 52.7% were male. 17.3% were initially diagnosed with AP. Mortality was significantly higher in those diagnosed with AP than non-AP during admission (27.6% vs 19.0%, p = 0.024) and at 1 year (64.2% vs 53.1%, p = 0.018), with survival analysis showing a median survival time of 62 days and 274 days in AP and non-AP, respectively (χ2 = 9.2, p = 0.002). However, the initial diagnosis of AP was not an independent risk factor for poor prognosis in multivariable analysis. Old age, frailty and cardio-respiratory comorbidities were the main factors associated with death. CONCLUSION: The greater mortality in AP may be a result of increased frailty rather than the diagnosis of aspiration itself. This supports our proposal for a paradigm shift from making predictions based on the potentially futile labelling of AP or non-AP, to considering frailty and overall condition of the patient.

Is polypharmacy a risk factor for aspiration pneumonia in older adults? A case-control study.

INTRODUCTION: The incidence of aspiration pneumonia and the number of medicines prescribed increase with older age. Many medicines pose a risk for aspiration pneumonia, especially those that decrease swallowing function. Older adults with polypharmacy often receive a combination of these medicines. This study aimed to clarify whether polypharmacy is a risk factor for aspiration pneumonia. METHODS: Older adults aged ≥ 65 years receiving oral medicines were included in this case-control study. Patients hospitalized for pneumonia served as the case group, and other age-matched hospitalized patients served as the control group. Patient data were collected retrospectively, and logistic regression analysis was performed using items that showed significant differences in the univariate analysis as explanatory variables. RESULTS: Logistic regression analysis revealed that the number of medicines was not a risk factor for aspiration pneumonia; however, it was associated with the Functional Oral Intake Scale score, male sex, body mass index, and number of comorbidities. CONCLUSION: Although polypharmacy is often defined only by the number of medicines, it is not a risk factor for aspiration pneumonia. A detailed comparison of prescription medicines between the pneumonia and non-pneumonia groups is necessary.

Retrograde Migration of a Percutaneous Endoscopic Gastro-Jejunal Tube Into the Esophagus.

Percutaneous endoscopic gastrostomy (PEG) and percutaneous endoscopic gastro-jejunal (PEG-J) tube placement are both common procedures regularly performed on patients requiring nutritional support. These procedures may be complicated by infection, hemorrhage, fistulization, or tube migration. We present an extremely rare case of a patient with a PEG-J tube that migrated into the esophagus.
