Abstract
The global population is aging at an unprecedented rate, resulting in a growing and vulnerable elderly population in need of efficient comprehensive healthcare services that include long-term care and skilled nursing facilities. In this context, severe aspiration pneumonia, a condition that carries substantial morbidity, mortality, and financial burden, especially among elderly patients requiring admission to the intensive care unit, has attracted greater concern. Aspiration pneumonia is defined as a pulmonary infection related to aspiration or dysphagia in etiology. Prior episodes of coughing on food or liquid intake, a history of relevant underlying conditions, abnormalities on videofluoroscopy or water swallowing, and gravity-dependent shadow distribution on chest imaging are among the clues that suggest aspiration. Patients with aspiration pneumonia tend to be elderly, frail, and suffering from more comorbidities than those without this condition. Here, we comprehensively address the epidemiology, clinical characteristics, diagnosis, treatment, prevention, and prognosis of severe aspiration community-acquired pneumonia in the elderly to optimize care of this high-risk demographic, enhance outcomes, and minimize the healthcare costs associated with this illness. Emphasizing preventive measures and effective management strategies is vital in ensuring the well-being of our aging population.

J Oral Rehabil 2024. [PMID: 38816919 DOI: 10.1111/joor.13761] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 05/11/2024] [Accepted: 05/19/2024] [Indexed: 06/01/2024]
Abstract
BACKGROUND Low-intensity continuous inspiratory muscle training improves its strength. The abdominal muscles are the main expiratory muscles, and their training may improve expiratory muscle strength. Respiratory muscle strength regulates coughing effectiveness, which is critical for pneumonia management. In older people, risk factors for the development of pneumonia were respiratory muscle weakness and swallowing impairment. Currently, the impact of high-intensity intermittent inspiratory and abdominal muscle combined training on the respiratory, swallowing, and systemic muscles is unclear. OBJECTIVE We aimed to explore the effects of high-intensity inspiratory muscle training combined with or without abdominal muscle training on respiratory muscle strength as well as the strength, mass, and performance of swallowing and systemic muscles. METHODS Twenty-eight healthy adults were divided into two groups. Participants performed high-intensity intermittent inspiratory muscle single or its combination with abdominal muscle training for 4 weeks. Respiratory muscle strength, swallowing muscle strength and mass, systemic muscle strength, mass and performance were measured at baseline, Week 2 and Week 4. RESULTS Both groups showed greater maximal respiratory pressures at Week 2 and Week 4 than baseline. Both groups showed improved tongue pressure and geniohyoid muscle thickness at Week 4. In addition, the combined training group improved body trunk muscle mass, handgrip strength and five-time chair stand test, whereas the single training group did not. CONCLUSION This study revealed that high-intensity inspiratory muscle training improved inspiratory muscle strength and swallowing muscle strength and mass. Moreover, inspiratory and abdominal muscle combined training showed an additional benefit of improving systemic muscle strength, mass and performance.

Abstract
PURPOSE Nurses' clinical reasoning skills regarding impaired swallowing can help prevent patient complications and maintain quality of life. Clinical reasoning skills need content-validated defining characteristics (DCs). We aimed to validate the content of these DCs for nursing diagnosis "impaired swallowing." METHODS Content validation of the DCs was performed by 275 dysphagia nursing experts in Japan, using 3 rounds of the Delphi technique and Fehring's Diagnostic Content Validation (DCV) model. Three rounds of questionnaires on 84 DCs were completed via printed mail. FINDINGS The valid response rates for each round were as follows: round 1, 90.2%; round 2, 77.8%; and round 3, 71.3%. Of the 84 DCs, 77 that met the consensus criteria were categorized as major (n = 18), minor (n = 45), and excluded (n = 14). There were four minor DCs other than the oral, pharyngeal, and esophageal phases. DCs listed from outside NANDA-I included 12 major, 16 minor, and 3 excluded characteristics. Of the NANDA-I DCs, 5 were no consensus and 11 were excluded. The total DCV score for the 63 major and minor DCs was 0.8. CONCLUSIONS Our results recommend the addition of 28 DCs and the exclusion of 11 for the NANDA-I nursing diagnosis "impaired swallowing" (00103). Major DCs were prominent indicators of impaired swallowing and signs of aspiration or pharyngeal residuals. Minor DCs included not only the three phases but also other signs necessary for a comprehensive understanding of impaired swallowing. IMPLICATIONS FOR NURSING PRACTICE This validation study strengthens the clinical usefulness of the DCs for impaired swallowing, which can improve nurses' clinical reasoning skills. Major and minor DCs can increase the awareness of impaired swallowing and enable accurate intervention, thereby preventing patient complications and maintaining quality of life.

Abstract
Aspiration pneumonia is a lower respiratory tract infection that results from inhalation of foreign material, often gastric and oropharyngeal contents. It is important to distinguish this from a similar entity, aspiration with chemical pneumonitis, as treatment approaches may differ. An evolving understanding of the human microbiome has shed light on the pathogenesis of aspiration pneumonia, suggesting that dysbiosis, repetitive injury, and inflammatory responses play a role in its development. Risk factors for aspiration events involve a complex interplay of anatomical and physiological dysfunctions in the nervous, gastrointestinal, and pulmonary systems. Current treatment strategies have shifted away from anaerobic organisms as leading pathogens. Prevention of aspiration pneumonia primarily involves addressing oropharyngeal dysphagia, a significant risk factor for aspiration pneumonia, particularly among elderly individuals and those with cognitive and neurodegenerative disorders.

High throughput sequencing technology reveals alteration of lower respiratory tract microbiome in severe aspiration pneumonia and its association with inflammation. INFECTION, GENETICS AND EVOLUTION : JOURNAL OF MOLECULAR EPIDEMIOLOGY AND EVOLUTIONARY GENETICS IN INFECTIOUS DISEASES 2023; 116:105533. [PMID: 37995886 DOI: 10.1016/j.meegid.2023.105533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 10/18/2023] [Accepted: 11/20/2023] [Indexed: 11/25/2023]
Abstract
BACKGROUND Aspiration pneumonia is a common and severe clinical condition. The microbiome present in the lower respiratory tract plays a crucial role in regulating human inflammatory response. However, the relationship between the altered lower respiratory tract microbiome and inflammation in aspiration pneumonia remains inadequately explored. PURPOSE To investigate the alteration of the lower respiratory tract microbiome in severe aspiration pneumonia patients and explore the potential correlation between microbiome components and inflammatory response. METHOD Patients in the severe aspiration pneumonia group and control group were enrolled from the intensive care unit of Jinshan Hospital, Fudan University between December 31, 2020 and August 19, 2021. Sputum specimens were collected from all participants and subsequently subjected to 16S rDNA high throughput sequencing technology. The concentration of inflammatory cytokines in serum was measured using enzyme-linked immunosorbent assay (ELISA) kits, and collected data including patients' demographic information, clinical data, and laboratory examination results were recorded for further analysis. RESULTS Alteration in the lower respiratory tract microbiome was observed in severe aspiration pneumonia. Compared to the control group, a significant decrease in the relative abundance of Firmicutes was found at the phylum level (P < 0.01). At the family level, the relative abundance of Corynebacteriaceae, Enterobacteriaceae and Enterococcaceae increased significantly (P < 0.001, P < 0.05, P < 0.01). There were no significant differences in community diversity of the lower respiratory tract between the two groups. Patients in the severe aspiration pneumonia group exhibited significantly higher levels of inflammation compared to those in the control group. Correlation analysis showed that the relative abundance of Corynebacteriaceae was positively correlated with the expression level of IL-1β and IL-18 (P = 0.002, P = 0.02); the relative abundance of Enterobacteriaceae was negatively correlated with IL-4 (P = 0.011); no other significant correlations have been identified between microbiome and inflammatory indicators thus far (P > 0.05). CONCLUSIONS Alteration of the lower respiratory tract microbiome is critically involved in inflammation and disease progression in severe cases of aspiration pneumonia. The potential inflammation regulation properties of the microbiome hold promising value for developing novel therapeutic approaches aimed at mitigating the severity of the disease.

Abstract
Background Aspiration Pneumonia (AP) is a leading cause of death in patients with Acute Ischemic Stroke (AIS). Early detection, diagnosis and effective prevention measures are crucial for improving patient prognosis. However, there is a lack of research predicting AP occurrence after AIS. This study aimed to identify risk factors and develop a nomogram model to determine the probability of developing AP after AIS. Method A total of 3258 AIS patients admitted to Jinshan Hospital of Fudan University between January 1, 2016, and August 20, 2022, were included. Among them, 307 patients were diagnosed with AP (AP group), while 2951 patients formed the control group (NAP group). Univariate and multivariate logistic regression analyses were conducted to identify relevant risk factors for AP after AIS. These factors were used to establish a scoring system and develop a nomogram model using R software. Results Univariate analysis revealed 20 factors significantly associated (P < 0.05) with the development of AP after AIS. These factors underwent multivariate logistic regression analysis, which identified age (elderly), National Institute of Health Stroke Scale (NIHSS) score, dysphagia, atrial fibrillation, cardiac insufficiency, renal insufficiency, hepatic insufficiency, elevated Fasting Blood Glucose (FBG), elevated C-Reactive Protein (CRP), elevated Neutrophil percentage (NEUT%), and decreased prealbumin as independent risk factors. A nomogram model incorporating these 11 risk factors was constructed, with a C-index of 0.872 (95 % CI: 0.845-0.899), indicating high accuracy. Calibration and clinical decision analyses demonstrated the model's reliability and clinical value. Conclusion A nomogram model incorporating age, NIHSS score, dysphagia, atrial fibrillation, cardiac insufficiency, renal insufficiency, hepatic insufficiency, FBG, CRP, NEUT%, and prealbumin effectively predicts AP risk in AIS patients. This model provides guidance for early intervention strategies, enabling the identification of high-risk individuals for timely preventive measures.

Abstract
Respiratory-related dysphagia and aspiration pneumonia can be attributed to multiple causes. However, reproduction of multiple factor-related respiratory distress and aspiration pneumonia in a single animal model is challenging. To validate animals with vagal nerve palsy as novel models for severe aspiration pneumonia associated with respiratory distress, we investigated the effects of unilateral vagotomy on the swallowing function and severity of pneumonia after forced aspiration in mice. Unilateral vagotomy was performed in C57BL6 male mice that subsequently underwent evaluation of swallowing function by videofluoroscopic swallow study (VFSS) and histological assessments for aspiration pneumonia induced by lipopolysaccharide (LPS). VFSS examinations demonstrated that unilateral vagotomy did not cause apparent aspiration in mice, but it resulted in a significant loss of body weight (BW) due to decreased oral intake. In addition, when aspiration pneumonia was induced by forced administration of LPS, significantly prolonged BW loss and severe infiltration of inflammatory cells associated with aspiration pneumonia were observed in the mice that underwent unilateral vagotomy. In conclusion, the vagotomized mice showed appropriate characteristics as a model of aspiration pneumonia caused by multiple factors, including the paralysis of vocal fold movement and respiratory distress. This model can help elucidate the pathogenesis of aspiration pneumonia and the treatment methods for the respiration-compromised model.

Abstract
PURPOSE Severe community-acquired pneumonia (sCAP) is associated with high morbidity and mortality, and whilst European and non-European guidelines are available for community-acquired pneumonia, there are no specific guidelines for sCAP. METHODS The European Respiratory Society (ERS), European Society of Intensive Care Medicine (ESICM), European Society of Clinical Microbiology and Infectious Diseases (ESCMID), and Latin American Thoracic Association (ALAT) launched a task force to develop the first international guidelines for sCAP. The panel comprised a total of 18 European and four non-European experts, as well as two methodologists. Eight clinical questions for sCAP diagnosis and treatment were chosen to be addressed. Systematic literature searches were performed in several databases. Meta-analyses were performed for evidence synthesis, whenever possible. The quality of evidence was assessed with GRADE (Grading of Recommendations, Assessment, Development and Evaluation). Evidence to Decision frameworks were used to decide on the direction and strength of recommendations. RESULTS Recommendations issued were related to diagnosis, antibiotics, organ support, biomarkers and co-adjuvant therapy. After considering the confidence in effect estimates, the importance of outcomes studied, desirable and undesirable consequences of treatment, cost, feasibility, acceptability of the intervention and implications to health equity, recommendations were made for or against specific treatment interventions. CONCLUSIONS In these international guidelines, ERS, ESICM, ESCMID, and ALAT provide evidence-based clinical practice recommendations for diagnosis, empirical treatment, and antibiotic therapy for sCAP, following the GRADE approach. Furthermore, current knowledge gaps have been highlighted and recommendations for future research have been made.

Abstract
BACKGROUND Severe community-acquired pneumonia (sCAP) is associated with high morbidity and mortality, and while European and non-European guidelines are available for community-acquired pneumonia, there are no specific guidelines for sCAP. MATERIALS AND METHODOLOGY The European Respiratory Society (ERS), European Society of Intensive Care Medicine (ESICM), European Society of Clinical Microbiology and Infectious Diseases (ESCMID) and Latin American Thoracic Association (ALAT) launched a task force to develop the first international guidelines for sCAP. The panel comprised a total of 18 European and four non-European experts, as well as two methodologists. Eight clinical questions for sCAP diagnosis and treatment were chosen to be addressed. Systematic literature searches were performed in several databases. Meta-analyses were performed for evidence synthesis, whenever possible. The quality of evidence was assessed with GRADE (Grading of Recommendations, Assessment, Development and Evaluation). Evidence to Decision frameworks were used to decide on the direction and strength of recommendations. RESULTS Recommendations issued were related to diagnosis, antibiotics, organ support, biomarkers and co-adjuvant therapy. After considering the confidence in effect estimates, the importance of outcomes studied, desirable and undesirable consequences of treatment, cost, feasibility, acceptability of the intervention and implications to health equity, recommendations were made for or against specific treatment interventions. CONCLUSIONS In these international guidelines, ERS, ESICM, ESCMID and ALAT provide evidence-based clinical practice recommendations for diagnosis, empirical treatment and antibiotic therapy for sCAP, following the GRADE approach. Furthermore, current knowledge gaps have been highlighted and recommendations for future research have been made.

Sunday AB, Nyasa RB, Mokake M. The influence of COVID-19 barrier measures on the positivity rate of typhoidal salmonellosis and amoebiasis in the Buea Health District, South West Region of Cameroon. PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0001854. [PMID: 37186243 PMCID: PMC10132537 DOI: 10.1371/journal.pgph.0001854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/08/2022] [Accepted: 04/04/2023] [Indexed: 05/17/2023]
Abstract
Typhoidal salmonellosis and amoebiasis are prevalent in the Buea Health District (BHD) and it is evident that hand hygiene can reduce the transmissibility of these diseases. The barrier measures enforced by the government, in the wake of the corona virus disease 2019 (COVID-19) pandemic has led to behavioural changes which may have had an influence on the positivity rate of these diseases. This study seeks to determine the influence of COVID-19 barrier measures and the implementation of COVID-19 vaccination on the positivity rate of typhoidal salmonellosis and amoebiasis in the BHD. A retrospective study, with purposive and random sampling methods were used to select health facilities in BHD, whose laboratory records were reviewed using a data extraction form to obtain health information of patients who tested for typhoidal salmonella and/or Entamoeba histolytica from June 1, 2018 to December 31, 2021. Chi-square test was used to compare the positivity rate in the pre-and-COVID-19 and in the pre-and-vaccination era. The positivity rate of typhoidal salmonellosis and amoebiasis dropped from 57.8% and 2.7% in the pre-COVID-19 era to 34% and 1.8% in the COVID-19 era respectively, which were significant (χ2 = 945.8; P<0.001 and χ2 = 11.8; P = 0.001 respectively). Within the COVID-19 era, the positivity rate of salmonellosis and amoebiasis decreased from 39% and 2.6% before the implementation of COVID-19 vaccination to 27.7% and 0.8% respectively in the COVID-19 vaccination era and these differences were significant (χ2 = 149.1; P<0.001 and χ2 = 33.8; P<0.001 respectively). However, the positivity rate of salmonellosis between the rainy (43.5%) and the dry (42.8%) seasons and amoebiasis between the rainy (2.2%) and the dry (2%) seasons were not significantly different (χ2 = 0.6; P = 0.429 and χ2 = 0.54; P = 0.463 respectively). A significant decline in the positivity rate of typhoidal salmonellosis and amoebiasis was observed after the implementation of COVID-19 barrier measures and vaccination.

Abstract
Introduction Early detection of dysphagia risk, initiating rehabilitation, and resumption of appropriate diet based on swallowing function is important during deep neck infection (DNI) control. This study aimed to evaluate the extent of cervical abscess development, particularly in the deep neck space, and its relationship to postoperative swallowing function. Methods A retrospective chart review was performed for all DNI cases treated between April 2015 and April 2021. Deep neck spaces were divided into categories based on computed tomography findings. Functional Oral Intake Scale (FOIS) scores of 4 or higher was defined as normal or slight swallowing disorder and 3 or lower as dysphagia. Results Seventeen cases were included in the analysis. Based on FOIS, 14 cases were classified into the dysphagia group at 2 weeks after surgery, 11 cases at 4 weeks, and 8 cases at 8 weeks. There was no significant difference between the location of the abscess and dysphagia at 2 weeks after surgery. Patients with anterior cervical space abscess significantly increased dysphagia 4 weeks (p = 0.018) and 8 weeks (p = 0.036) after surgery. Conclusion Abscess formation in the anterior cervical space may be associated with prolonged dysphagia after treatment due to inflammation and scarring of the muscles associated with swallowing.

Abstract
Introduction: This study investigates risk factors underlying the prognosis of severe aspiration pneumonia (SAP) in intensive care unit (ICU) patients and attempts to provide early prognosis reference for clinical tasks. Methods: Patients diagnosed with SAP and admitted to the ICU of Jinshan Hospital, Fudan University, Shanghai, China, between January 2021 and December 2021 were recruited in this retrospective cohort study. Clinical data on a patient's general condition, underlying diseases, laboratory indicators, and 90-day outcomes (survival or death) were recorded. Results: Multivariate logistic regression analysis showed that a low platelet count was an independent risk factor affecting the prognosis of death (OR = 6.68, 95% CI:1.10-40.78, β = 1.90, P = 0.040). Receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of variables; cut-off values were calculated and the area under the curve was 0.7782 [(95% CI:0.686-0.871), p < 0.001] for the prediction of death at 90 days in all patients. The Kaplan-Meier curve used for survival analysis showed that, compared with the normal platelet group, the overall survival rate of patients with low platelet levels was significantly lower, and the difference was statistically significant [HR = 2.11, (95% CI:1.47-3.03), p = 0.0001, z = 4.05, X 2 = 14.89]. Cox regression analysis, used to further verify the influence of prognostic risk factors, showed that a concurrent low platelet count was the most important independent risk factor affecting the prognosis of SAP (HR = 2.12 [95% CI:1.12-3.99], X2 = 50.95, p = 0.021). Conclusion: These findings demonstrate an association between SAP mortality and platelet levels on admission. Thus, platelet level at admission may be used as a readily available marker for assessing the prognosis of patients with SAP.

Abstract
Aspiration pneumonia (AP) is the leading cause of death among the elderly in Japan. The factors associated with the survival of elderly patients with AP are investigated in this retrospective observational study. Patients with AP over the age of 60 who were assessed for swallowing function in our hospital between April 2015 and March 2016 were eligible. Data on patients' body mass index (BMI), food consistency, and Karnofsky performance status were collected from medical records in hospital and again after recovery. Following hospital discharge, eligible patients were sent questionnaires containing information about their physical conditions, such as body weight and the Japanese version of the functional independence measure. Respondents were divided into two groups: those who died and those who survived, and the factors associated with patient mortality were investigated. There were 19 responses from 50 eligible patients, and seven patients died. The participants' average age was 81 years (SD 9.32). There were ten male participants (52.6%, p=1.00), and there were no significant differences in the mortality and survival groups. The most significant finding was that BMI was significantly lower in the patients who died (p=0.037, Cohen’s d=1.10). Fisher's exact tests clearly demonstrated that patients with a BMI <19.9 had a higher mortality rate (p=0.017). Lower BMI may be associated with increased mortality in elderly patients with a history of AP. In general practice, BMI is simple to measure and may allow for an easy assessment of the risk of AP-related mortality

Abstract
In the 21st century, aspiration pneumonia (ASP) is very common in older patients, and has a high mortality rate. ASP is diagnosed following confirmation of inflammatory findings in the lungs and overt aspiration or the existence of dysphagia. It is dominant in hospitalized community-acquired pneumonia (CAP), nursing and healthcare-associated pneumonia (NHCAP), and hospital-acquired pneumonia (HAP). The incidence of ASP is increasing every year. The human and experimental animal data revealed that micro-aspiration due to dysphagia during the night is the central mechanism of ASP. Therefore, the precise assessment of swallowing function is the key to diagnose ASP. From a therapeutic point of view, an appropriate administration of antibiotics, as well as a comprehensive approach for dysphagia plays a pivotal role in the prognosis and recovery from ASP. The non-pharmacologic approach, including swallowing rehabilitation and oral care, and a pharmacologic approach including ACE inhibitors and bronchodilators, are essential modalities for treatment and prevention of ASP. The clinical data of NHCAP provides us with a promising treatment strategy for ASP.
