Investigation of predictors for in-hospital death or long-term hospitalization in community-acquired pneumonia with risk factors for aspiration. Eur Clin Respir J 2024; 11:2335721. [PMID: 38586609 PMCID: PMC10997353 DOI: 10.1080/20018525.2024.2335721] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Accepted: 03/22/2024] [Indexed: 04/09/2024] Open
Abstract
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.

Anti-biofilm effectiveness of protocols for cleaning complete dentures in hospitalized patients: a randomized controlled trial. J Appl Oral Sci 2024; 32:e20230381. [PMID: 38537031 PMCID: PMC10984580 DOI: 10.1590/1678-7757-2022-0381] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Revised: 01/15/2024] [Accepted: 02/01/2024] [Indexed: 04/01/2024] Open
Abstract
BACKGROUND Denture biofilm acts as a potential reservoir for respiratory pathogens, considerably increasing the risk of lung infections, specifically aspiration pneumonia, mainly 48h after hospital admission. The establishment of a straightforward, affordable, and applicable hygiene protocol in a hospital environment for the effective control of denture biofilm can be particularly useful to prevent respiratory infections or reduce the course of established lung disease. OBJECTIVES To evaluate the anti-biofilm effectiveness of denture cleaning protocols in hospitalized patients. METHODOLOGY The maxillary complete dentures (MCDs) of 340 hospitalized participants were randomly cleaned once using one of the following 17 protocols (n=20): brushing with distilled water, toothpaste, or neutral liquid soap (controls); immersion in chemical solutions (1% sodium hypochlorite, alkaline peroxide, 0.12% or 2% chlorhexidine digluconate), or microwave irradiation (650 W for 3 min) combined or not with brushing. Before and after the application of the protocols, the biofilm of the intaglio surface of the MCDs was evaluated using two methods: denture biofilm coverage area (%) and microbiological quantitative cultures on blood agar and Sabouraud Dextrose Agar (CFU/mL). Data were subjected to the Wilcoxon and Kruskal-Wallis tests (α=0.05). RESULTS All 17 protocols significantly reduced the percentage area of denture biofilm and microbial and fungal load (P<0.05). The highest percentage reductions in the area of denture biofilm were observed for 1% hypochlorite solution with or without brushing and for 2% chlorhexidine solution and microwave irradiation only in association with brushing (P<0.05). The greatest reductions in microbial and fungal load were found for the groups that used solutions of 2% chlorhexidine and 1% hypochlorite and microwave irradiation, regardless of the association with brushing (P<0.05). CONCLUSIONS A single immersion for 10 min in 1% sodium hypochlorite, even in the absence of brushing, proved to be a straightforward, rapid, low-cost, and effective protocol for cleaning the dentures of hospitalized patients.

Abstract
Capture and real-time recording of precise body movements using strain sensors provide personal information for healthcare monitoring and management. To acquire this information, a sensor that conforms to curved irregular surfaces, including biological tissue, is desired to record complex body movements while acting like a second skin to avoid interference with the movements. In this study, we developed a thin-film-type capacitive strain sensor that is flexible and stretchable on the surface of a living body. We fabricated conductive polymeric ultrathin films ("nanosheets") comprising polystyrene-block-polybutadiene (SB) elastomers and single-walled carbon nanotubes (SWCNTs) (i.e., SWCNT-SB nanosheets) via gravure coating; the SWCNT-SB-coated nanosheets were used as the flexible electrode in a capacitive strain sensor. The dielectric (DE) layer was then prepared using the silicone elastomer Ecoflex 00-30 because its Young's modulus is comparable to that of the epidermis. The normalized capacitance changes (ΔC/C0) in the sensor increased with increasing tensile strain over a range from 0-100%, indicating that the proposed sensor can measure the strain of biological movements, including those of skin and blood vessels. To improve sensor conformability further, the effect of sensor thickness on the gauge factor (GF) was investigated using thinner DE layers by focusing on their flexural rigidity. As a result, the GF increased from 0.64 to 1.13 as the DE layer thickness decreased from 260 to 40 μm. Finally, we evaluated the fabricated sensor's signal stability and mechanical durability, including during wireless sensing when applied to human skin and a vascular model. The ΔC/C0 values varied in response to the bending motion of a finger, dilation of a blood vessel, and the swallowing movement of the throat. These results indicate that our capacitive strain sensor is conformable and functional on biological tissue to enable monitoring of dynamic biological movements (e.g., pulse rate and arterial dilation) without wearer discomfort.

Predicting ventilator-associated pneumonia in elderly patients requiring mechanical ventilation through the detection in tracheal aspirates. Postgrad Med 2023; 135:831-841. [PMID: 38032178 DOI: 10.1080/00325481.2023.2288559] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 11/23/2023] [Indexed: 12/01/2023]
Abstract
OBJECTIVE In this study, we evaluated the clinical utility of tracheal aspirates α-amylase (AM), pepsin, and lipid-laden macrophage index (LLMI) in the early diagnosis of ventilator-associated pneumonia (VAP) in elderly patients on mechanical ventilation. METHODS Within 96 hours of tracheal intubation, tracheal aspirate specimens were collected from elderly patients on mechanical ventilation; AM, pepsin, and LLMI were detected, and we analyzed the potential of each index individually and in combination in diagnosing VAP. RESULTS Patients with VAP had significantly higher levels of AM, pepsin, and LLMI compared to those without VAP (P < 0.001), and there was a positive correlation between the number of pre-intubation risk factors of aspiration and the detection value of each index in patients with VAP (P < 0.001). The area under a receiver operating characteristic (ROC) curve (AUC) of AM, pepsin, and LLMI in diagnosis of VAP were 0.821 (95% CI:0.713-0.904), 0.802 (95% CI:0.693-0.892), and 0.621 (95% CI:0.583-0.824), the sensitivities were 0.8815, 0.7632, and 0.6973, the specificities were 0.8495, 0.8602, and 0.6291, and the cutoff values were 4,321.5 U/L, 126.61 ng/ml, and 173.5, respectively. The AUC for the combination of indexes in diagnosing VAP was 0.905 (95% CI:0.812-0.934), and the sensitivity and specificity were 0.9211 and 0.9332, respectively. In the tracheal aspirate specimens, the detection rate of AM ≥ cutoff was the highest, while it was the lowest for LLMI (P < 0.001). The detection rates of AM ≥ cutoff and pepsin ≥ cutoff were higher within 48 hours after intubation than within 48-96 hours after intubation (P < 0.001). In contrast, the detection rate of LLMI ≥ cutoff was higher within 48-96 hours after intubation than within 48 hours after intubation (P < 0.001). The risk factors for VAP identified using logistic multivariate analysis included pre-intubation aspiration risk factors (≥3), MDR bacteria growth in tracheal aspirates, and tracheal aspirate AM ≥ 4,321.5 U/L, pepsin ≥ 126.61 ng/ml, and LLMI ≥ 173.5. CONCLUSION The detection of AM, pepsin, and LLMI in tracheal aspirates has promising clinical utility as an early warning biomarker of VAP in elderly patients undergoing mechanical ventilation.

Clinical Utility of Pepsin and Bile Acid in Tracheal Secretions for Accurate Diagnosis of Aspiration in ICU Patients. J Clin Med 2023; 12:5466. [PMID: 37685534 PMCID: PMC10487459 DOI: 10.3390/jcm12175466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 08/15/2023] [Accepted: 08/20/2023] [Indexed: 09/10/2023] Open
Abstract
BACKGROUND Aspiration of stomach content or saliva in critical conditions-e.g., shock, intoxication, or resuscitation-can lead to acute lung injury. While various biomarkers in bronchoalveolar lavage fluids have been studied for diagnosing aspiration, none have been conclusively established as early indicators of lung damage. This study aims to evaluate the diagnostic value of pepsin, bile acid, and other biomarkers for detecting aspiration in an intensive care unit (ICU). MATERIALS AND METHODS In this study, 50 ICU patients were enrolled and underwent intubation before admission. The evaluation of aspiration was based on clinical suspicion or documented instances of observed events. Tracheal secretion (TS) samples were collected within 6 h after intubation using sterile suction catheters. Additional parameters, including IL-6, pepsin, and bile acid, were determined for analysis. Pepsin levels were measured with an ELISA kit, while bile acid, uric acid, glucose, IL-6, and pH value in the tracheal secretion were analyzed using standardized lab methods. RESULTS The 50 patients admitted to the ICU with various diagnoses. The median survival time for the entire cohort was 52 days, and there was no significant difference in survival between patients with aspiration pneumonia (AP) and those with other diagnoses (p = 0.69). Among the AP group, the average survival time was 50.51 days (±8.1 SD; 95% CI 34.63-66.39), while patients with other diagnoses had a mean survival time of 32.86 days (±5.1 SD; 95% CI 22.9-42.81); the survival group comparison did not yield statistically significant results. The presence of pepsin or bile acid in TS patients did not significantly impact survival or the diagnosis of aspiration. The p-values for the correlations between pepsin and bile acid with the aspiration diagnosis were p = 0.53 and p > 0.99, respectively; thus, pepsin and bile acid measurements did not significantly affect survival outcomes or enhance the accuracy of diagnosing aspiration pneumonia. CONCLUSIONS The early and accurate diagnosis of aspiration is crucial for optimal patient care. However, based on this study, pepsin concentration alone may not reliably indicate aspiration, and bile acid levels also show limited association with the diagnosis. Further validation studies are needed to assess the clinical usefulness and reliability of gastric biomarkers in diagnosing aspiration-related conditions. Such future studies would provide valuable insights for improving aspiration diagnosis and enhancing patient care.

Abstract
Postoperative pneumonia (POP) is a common postoperative complication. Negative consequences associated with POP included prolonged hospital length of stay, more frequent intensive care unit (ICU) stays, and a higher rate of sepsis, readmission, and mortality. This meta-analysis aimed to assess the incidence and risk factors associated with POP after hip fracture surgery in elderly patients. PubMed, Web of Science, and Cochrane Library were searched (up to March 31, 2022). All studies on the risk factors for POP after hip fracture surgery in elderly patients, published in English, were reviewed. The qualities of the included studies were assessed using the Newcastle-Ottawa Scale. Data were pooled, and a meta-analysis was performed. Ten studies, including 12,084 geriatric patients undergoing hip fracture surgery, were included. Of these 12,084 patients, POP occurred in 809 patients. The results indicated that age (mean difference [MD] = 4.95, 95% confidence interval [CI]: 3.22-6.69), male (odds ratio [OR] = 1.41, 95% CI: 1.02-1.93), the American Society of Anaesthesiologists classification ≥3 (OR = 3.48, 95% CI: 1.87-6.47), dependent functional status (OR = 5.23, 95% CI: 2.18-12.54, P = 0.0002), smoking (OR = 1.33, 95% CI: 1.07-1.65), chronic obstructive pulmonary disease (OR = 3.76, 95% CI: 2.07-6.81), diabetes mellitus (OR = 1.19, 95% CI: 1.01-1.40), coronary heart disease (OR = 1.74, 95% CI: 1.23-2.46), arrhythmia (OR = 1.47, 95% CI: 1.01-2.14), cerebrovascular disease (OR = 1.88, 95% CI: 1.56-2.27), dementia (OR = 2.36, 95% CI: 1.04-5.36), chronic renal failure (OR = 1.85, 95% CI: 1.29-2.67), hip arthroplasty (OR = 1.30, 95% CI: 1.08-1.56), delayed surgery (OR = 6.40, 95% CI: 3.00-13.68), preoperative creatinine (MD = 5.32, 95% CI: 0.55-10.08), and preoperative serum albumin (MD = -3.01, 95% CI: -4.21 - -1.80) were risk factors for POP. Related prophylactic measures should be provided in geriatric patients with the above-mentioned risk factors to prevent POP after hip fracture surgery.

[PMID: 35509063 PMCID: PMC9069761 DOI: 10.1186/s41479-022-00096-z] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Accepted: 04/11/2022] [Indexed: 12/27/2022] Open
Abstract
Bacterial pneumonia is one of the most serious public health issues owing to its medical and economic costs, which result in increased morbidity and mortality in people of all ages around the world. Furthermore, antimicrobial resistance has risen over time, and the advent of multi-drug resistance in GNB complicates therapy and has a detrimental impact on patient outcomes. The current review aimed to summarize bacterial pneumonia with an emphasis on gram-negative etiology, pathogenesis, risk factors, resistance mechanisms, treatment updates, and vaccine concerns to tackle the problem before it causes a serious consequence. In conclusion, the global prevalence of GNB in CAP was reported 49.7% to 83.1%, whereas in VAP patients ranged between 76.13% to 95.3%. The most commonly reported MDR-GNB causes of pneumonia were A. baumannii, K. pneumoniae, and P. aeruginosa, with A. baumannii isolated particularly in VAP patients and the elderly. In most studies, ampicillin, tetracyclines, amoxicillin-clavulanic acid, cephalosporins, and carbapenems were shown to be highly resistant. Prior MDR-GNB infection, older age, previous use of broad-spectrum antibiotics, high frequency of local antibiotic resistance, prolonged hospital stays, ICU admission, mechanical ventilation, and immunosuppression are associated with the MDR-GNB colonization. S. maltophilia was reported as a severe cause of HAP/VAP in patients with mechanically ventilated and having hematologic malignancy due to its ability of biofilm formation, site adhesion in respiratory devices, and its intrinsic and acquired drug resistance mechanisms. Effective combination therapies targeting PDR strains and drug-resistant genes, antibiofilm agents, gene-based vaccinations, and pathogen-specific lymphocytes should be developed in the future.

Abstract
Klebsiella species cause infections at multiple sites, including lung, urinary tract, bloodstream, wound or surgical site, and brain. These infections are more likely to occur in people with preexisting health conditions. Klebsiella pneumoniae (K. pneumoniae) has emerged as a major pathogen of international concern due to the increasing incidences of hypervirulent and carbapenem-resistant strains. It is imperative to understand risk factors, prevention strategies, and therapeutic avenues to treat multidrug-resistant Klebsiella infections. Here, we highlight the epidemiology, risk factors, and control strategies against K. pneumoniae infections to highlight the grave risk posed by this pathogen and currently available options to treat Klebsiella-associated diseases.

Abstract
We aimed to clarify the physical factors associated with the incidence of aspiration pneumonia in a community-based integrated care unit. This retrospective cohort study included 412 patients aged 65 years or older admitted to a community-based integrated care unit. A new diagnosis of aspiration pneumonia made by the attending physician based on physical examination, imaging findings, and blood test data after 48 h of admission was considered as an incidence of aspiration pneumonia. Basic patient information, activities of daily living, swallowing function, nutritional status, cognitive function, oral health-related factors, and energy intake were retrospectively investigated. We classified the patients into a pneumonia group and a non-pneumonia group, and examined the factors associated with the development of aspiration pneumonia. The mean age was 86.9 ± 8.1 years, and the pneumonia group comprised 49 participants. Comparison between the groups showed significant differences in oral environment, denture use, cognitive functional independence measure, and discharge to home. In multivariate logistic regression analysis, oral environment (odds ratio (OR) = 0.229, 95% confidence interval (CI): 0.070–0.753, p = 0.015) and use of dentures (OR = 0.360, 95% CI: 0.172–0.754, p = 0.007) were independently associated with aspiration pneumonia. Oral care and the use of dentures may be effective in preventing aspiration pneumonia.

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.

Abstract
Introduction Oral care to older people in short-term care units is a complex and challenging everyday practice for nursing staff. Oral care research and knowledge about prerequisites and obstacles is extensive. However, there is a lack of knowledge about how nursing staff in short-term care units describe their satisfaction about provided oral care in order to maintain older people's oral health. Objective The purpose of this study was to describe how nursing staff perceive their satisfaction of oral care provided for older people in short-term care units and to identify oral care improvements. Methods This study reports on the results of two open-ended questions that were part of a larger study. Informants (n = 54) were nursing staff working in the involved short-term care units in municipalities from both densely and sparsely populated regions in central and northern Sweden. The answers to the open-ended questions were analyzed using content analysis. Results The analysis yielded one main category; “Working together to improve satisfaction with older people's oral care” and four subcategories: “Older people's oral health,” “Consideration and respect for the older person's autonomy,” “Having access to adequate products,” and “Working together in the same direction.” Conclusion Identification of older people's oral health problems together with adequate nursing intervention will increase older people's health outcomes and quality of life. However, regardless of work role, the nursing staff might have difficulty changing their behavior or transforming intentions into actions. Oral care is a complicated and proactive practice that requires nursing staff's attention as well as both educational and organizational initiatives. Working in a supportive and collaborative relationship provides prerequisites for optimal oral care in short-term care units.

Abstract
Background This study examined the association between parenteral energy/amino acid doses and in-hospital mortality among inpatients on long-term nil per os (NPO) status, using a medical claims database in Japan. Methods Hospitalized patients with aspiration pneumonia, aged 65 and older, and on more than 7-day NPO status were identified in a medical claims database between January 2013 and December 2018. Using multivariate logistic regression and regression analyses, we examined the association between mean parenteral energy/amino acid doses and in-hospital mortality, and secondarily, the association between prognosis (in-hospital mortality, inability to receive full oral intake, readmission, and hospital stay length) and 4 groups of mean amino acid doses (no dose: 0 g/kg/day; very low dose: >0, ≤0.3 g/kg/day; low dose: >0.3, ≤0.6 g/kg/day; moderate dose: >0.6 g/kg/day). Results The analysis population included 20 457 inpatients (≥80 years: 78.3%). In total, 5 920 mortalities were recorded. Increased amino acid doses were significantly associated with reduced in-hospital mortality (p < .001). With a no dose reference level, the odds ratios (95% confidence interval) of in-hospital mortality adjusted for potential confounders were 0.78 (0.72–0.85), 0.74 (0.67–0.82), and 0.69 (0.59–0.81) for very low, low, and moderate amino acid doses, respectively. Additionally, patients prescribed amino acid dose levels more than 0.6 g/kg/day had shorter hospitalization periods than those prescribed none. Conclusions Increased amino acid doses were associated with reduced in-hospital mortality. Sufficient amino acid administration is recommended for patients with aspiration pneumonia requiring NPO status.

Abstract
AIMS To evaluate the efficacy of multi-component interventions for prevention of hospital-acquired pneumonia in older patients hospitalized in geriatric wards. METHODS A randomized, parallel-group, controlled trial was undertaken in patients aged 65 and above who were admitted to a tertiary hospital geriatric unit from January 1, 2016 to June 30, 2018 for an acute non-respiratory illness. Participants were randomized by to receive either a multi-component intervention (consisting of reverse Trendelenburg position, dysphagia screening, oral care and vaccinations), or usual care. The outcome measures were the proportion of patients who developed hospital-acquired pneumonia during hospitalisation, and mean time from randomization to the next hospitalisation due to respiratory infections in 1 year. RESULTS A total of 123 participants (median age, 85; 43.1% male) were randomized, (n = 59) to intervention group and (n = 64) to control group. The multi-component interventions did not significantly reduce the incidence of hospital-acquired pneumonia but did increase the mean time to next hospitalisation due to respiratory infection (11.5 months vs. 9.5 months; P = 0.049), and reduced the risk of hospitalisation in 1 year (18.6% vs. 34.4%; P = 0.049). Implementation of multi-component interventions increased diagnoses of oropharyngeal dysphagia (35.6% vs. 20.3%; P < 0.001) and improved the influenza (54.5% vs 17.2%; P < 0.001) and pneumococcal vaccination rates (52.5% vs. 20.3%; P < 0.001). CONCLUSIONS The nosocomial pneumonia multi-component intervention did not significantly reduce the incidence of hospital-acquired pneumonia during hospitalisation but reduce subsequent hospitalisations for respiratory infections.

Abstract
BACKGROUND/OBJECTIVES This study aimed to describe real-world nutrition management patterns among inpatients hospitalized for aspiration pneumonia, using a medical claims database in Japan. METHODS Patients aged ≥65 years hospitalized for aspiration pneumonia treatment were identified in a medical claims database between January 2013 and December 2018, to evaluate nutrition management initiation and adjustment timing, factors associated with >7-days nil per os (NPO) status, prescribed nutrition doses, and types of parenteral nutrition solutions. Patients who received oral intake or enteral nutrition on the day of admission (Day 1) were excluded. RESULTS The analysis population included 72,315 inpatients. The median (first quartile, third quartile) initiation date of oral nutrition intake was Day 4 (3, 7) and 65.1% of patients received oral nutrition intake by Day 7. Factors associated with >7-day NPO included sex, BMI, treatment years, Barthel Index score, Japan Coma Scale score, and oxygen inhalation on the day of hospital admission. Amongst NPO patients on Day 7, only 5.3% were prescribed the recommended doses of ≥20 kcal/kg; 6.4% were prescribed ≥1.0 g/kg amino acids, and 5.7% were prescribed fat energy ratio at ≥15% of non-protein calories. Commonly prescribed parenteral nutrition solutions on Day 7 were carbohydrate/electrolyte solutions (52.8%) and peripheral parenteral nutrition solutions (49.0%). CONCLUSION Prescribed parenteral energy, amino acids, and fat during the NPO period were lower than the recommended doses in the majority of patients. Prescribing recommended doses of each of these component nutrients may be beneficial when managing parenteral nutrition of patients during NPO.

Abstract
BACKGROUND Increasing incidences of swallowing dysfunction, or dysphagia, a risk factor for aspiration pneumonia, are being reported in aging populations. AIMS To investigate the relationship between swallowing function and oral bacteria in independent, community-dwelling elderly. METHODS This study recruited 139 community-dwelling individuals aged ≥ 70 years with poor swallowing function. The presence of anaerobic (Prevotella spp. and Fusobacterium spp.) and aerobic bacteria was examined in the participants' oral cavity flora. Swallowing function was evaluated using a 30 mL water swallowing test. Multivariate logistic regression analyses were performed to examine the association between oral bacteria and swallowing function. RESULTS Swallowing function was assessed as abnormal in 2.9% and as abnormal in 47.5% of the subjects. The colony-forming units (CFUs/ml) of Prevotella spp. were associated with the swallowing dysfunction (odds ratio [OR] 3.45, 95% confidence interval [CI] 1.49-8.11). Further, CFUs/ml of Fusobacterium spp. and aerobes did not correlate with the swallowing dysfunction but were related with the number of teeth (OR 2.71; 95% CI 1.28-5.74, and OR 0.40; 95% CI, 0.18-0.91, respectively) CONCLUSIONS: Swallowing dysfunction in community-dwelling elderly is associated with increased abundance of Prevotella spp., which indirectly may be an increased risk factor for aspiration pneumonia.

Abstract
This study was based in a hospital setting. Patients with acute symptoms face a life-threatening crisis and often have systemic complications during the convalescence stage. During the acute stage, oral function does not work and oral hygiene status deteriorates. A gauze or sponge brush is generally used to wipe the oral cavity; however, this process does not clean the oral cavity enough. Effective oral care requires better methods. Patients participating in this study were all hospitalized by ambulance and with acute symptoms. During the convalescence stage, patients were assigned application of mucosal brushing or wiping by gauze or sponge brush by order of hospitalization. The effects were evaluated by the number of bacteria on the tongue surface, serum C-reactive protein (CRP) and body temperature. Changes in bacterial count, body temperature, and CRP were effectively reduced in the mucosal brushing group compared to the wiping by gauze or sponge brush group. Based on mixed effect modeling, the coefficient of mucosal brushing for CRP was −2.296 and for body temperature was −0.067 and statistically significant. This simple method can effectively prevent systemic complication of inpatients with deteriorated oral conditions. This method may also be effective for the elderly in nursing homes or perioperative oral-care management.

Abstract
Japan is the world’s leading aging society, and increasing medical expenses for elderly people is an urgent issue. Since aspiration pneumonia in elderly people with impaired swallowing function is a huge problem in Japan, their expected long-term clinical course should be clarified. Accordingly, we collected data from 991 elderly (≥75 years old) patients whose swallowing function was evaluated by Kitasato Institute Hospital’s speech therapists (January 1, 2010 to December 31, 2017). We analyzed the relationship between swallowing function and the subjects’ long-term prognosis. To clarify the prognostic factors of patients with dysphagia, we obtained their clinical information (age, gender, activities of daily living, nutritional status, availability of alternative feeding pathways such as percutaneous endoscopic gastrostomy, and cognitive function). We confirmed 372 death cases and stratified the cases into three groups using Fujishima’s swallowing ability grade, which is used to predict elderly people’s real-world life expectancy. Results showed the median survival days were 331 and 952 days in Groups I (Grades 1–3, n = 308) and II (Grades 4–6, n = 153), respectively, whereas the median survival days for Group III (Grades 7–10, n = 530) could not be calculated. We conducted a multivariate analysis using the Cox proportional hazards model with Group I, which revealed that initial grade and percutaneous endoscopic gastrostomy were significant prognostic factors for the subjects’ long-term survival. Nevertheless, further discussion is necessary, particularly to determine advanced care planning regarding indications for alternative feeding pathways in elderly patients with severe dysphagia, since percutaneous endoscopic gastrostomy could significantly prolong their survival.

Abstract
This was a prospective cohort design study that followed a group of older adults for up to 12 months. Two hundred and ninety-one participants with a mean age of 81.4 ± 9.1 years were recruited. Signs of aspiration were screened by the Yale Swallow Protocol. Variables investigated for risk were oromotor functions, self-perception of swallowing function, cognitive function, and medical history. Seventy participants were revisited for a follow-up aspiration screening 8 to 9 months later. Multivariate logistic regression found that male sex, need for assistance for feeding and mobility, reduced cognitive function, subjective judgement of swallowing function, and oromotor function were major variables that can be used to screen for older adults who may require referrals for swallowing assessment. Those who continue to show signs of aspiration across time exhibit a more frail profile than their counterparts who do not.

Abstract
Aim (a) To describe and compare perceptions of humanity aspects of oral care quality in relation to nursing staff in short‐term care units and intensive care units and older people in short‐term care units and their person‐related conditions; and (b) to compare humanity aspects of oral care quality perceptions between nursing staff and older people in short‐term care units. Design Cross‐sectional study. Self‐reported questionnaire and clinical assessments. Methods Nursing staff (N = 417) and older people (N = 74) completed the modified Quality of Care from a Patient Perspective instrument and person‐related items. Older people's oral health status was clinically assessed using the Revised Oral Assessment Guide. Data were analysed using descriptive and analytic statistics. The data were collected from 2013–2016. Results Nursing staff's perceptions of humanity aspects of oral care quality were related to gender, work role and care environment. Older people's perceptions of humanity aspects of oral care quality were related to self‐reported physical health. Nursing staff in short‐term care units perceived the subjective importance of humanity aspects of oral care quality higher compared with older people in short‐term care units.

Abstract
Background Pneumonia is a leading cause of hospitalization and death worldwide. However, studies focusing on risk factors of community-acquired pneumonia (CAP) in the home health care (HHC) population remain scarce. Aims This study aimed to evaluate risk factors associated with hospitalization for CAP among HHC patients in Taiwan. Methods This retrospective cross-sectional study extracted data from patients’ electronic medical records between 1 January 2017 and 31 December 2017. Multiple logistic regression analyses were performed to explore factors associated with hospitalization for CAP. Results In total, 598 patients (men/women: 236/362) were included. One hundred ninety-nine patients (33.28%) were hospitalized for pneumonia. Inpatients showed a higher proportion of the following: male sex, functional impairment, hypoalbuminemia, anemia, nasogastric tube use, excessive polypharmacy, stroke, dementia, heart failure, chronic respiratory disease, and chronic liver disease. Furthermore, nasogastric tube use (odds ratio [OR] 3.01, 95% confidence interval [CI] 1.88–4.82), anemia (OR 2.37, 95% CI 1.48–3.80), male sex (OR 2.14, 95% CI 1.43–3.20), chronic respiratory disease (OR 2.09, 95% CI 1.33–3.30), dementia (OR 1.94, 95% CI 1.27–2.97), heart failure (OR 1.69, 95% CI 1.11–2.56), and hypoalbuminemia (OR 1.57, 95% CI 1.03–2.40) significantly increased the risk of hospitalization for CAP. Conclusions Our results revealed risk factors associated with hospitalization for CAP in HHC patients. In addition to chronic diseases, malnutrition is an important risk factor. Caregivers should make prompt assessments and take preventive measures for such patients.

Abstract
This study aimed to determine predictive factors associated with poor outcomes among older adult inpatients in the convalescent rehabilitation ward. We also examined the validity of factors that were identified as predictive of poor outcomes. Study subjects were 104 older adult inpatients in the convalescent rehabilitation ward, divided into two groups based on outcome at discharge. Group I included the outcomes of death or transfer to an acute care hospital and Group II included all other outcomes. Data were retrospectively collected from older adults' medical records, including: activities of daily living, swallowing grade, nutritional index, and blood biochemistry data. Logistic regression analysis was used to extract predictive factors associated with poor outcomes. Next, we calculated the Stratum-specific likelihood ratio (SSLR) for each extracted factor. Two items were extracted as predictive factors with AUCs ≥ 0.7 : N-terminal pro-brain natriuretic peptide (NT-proBNP) and days from onset to hospitalization. The SSLRs showed the risk for a poor outcome increased when NT-proBNP was ≥ 2500 pg / ml, and when there were ≥ 35 days from onset to hospitalization. Our findings suggest these predictive factors provide a valid index to predict poor outcomes among older adults from the early stage of admission. J. Med. Invest. 67 : 304-310, August, 2020.

Abstract
Transcutaneous electrical sensory stimulation (TESS) devices are approved for use in Japan, but their safety when used through the neck skin for dysphagia rehabilitation has not been reported. This study aimed to verify the safety of TESS use through the neck skin. Twenty patients (mean age 86.5 ± 5.1 years) with aspiration pneumonia undergoing dysphagia rehabilitation were included in this retrospective observational and matched control study. We compared vital signs in 10 subjects who underwent swallowing rehabilitation with the TESS device, and matched control patients over 7 days. The results were the following: tachycardia, 0.60 ± 1.07 vs. 0.70 ± 0.67 days; high blood pressure, 0.40 ± 0.70 vs. 0.50 ± 1.08 days; low blood pressure, 0.40 ± 0.70 vs. 0.10 ± 0.32 days; low oxygen saturation, 0.60 ± 1.58 vs. 0.50 ± 1.08 days, p = 0.870; oxygen administration, 0.80 ± 2.20 vs. 1.20 ± 2.15 days; tachypnea, 0.50 ± 0.71 vs. 0.50 ± 0.53 days; elevated body temperature, 2.00 ± 1.41 vs. 1.60 ± 1.96 days. There were no significant differences in clinical stability between the TESS and control groups of patients with aspiration pneumonia. TESS through the neck appears safe as an intervention in dysphagia rehabilitation.

Abstract
The aim of this study was to design and evaluate muco-adhesive orally disintegrating tablets manufactured by microwave irradiation and containing polysaccharide. We prepared orally disintegrating tea tablets (ODTTs) containing a 1 w/w% mass fraction of one of five polysaccharides (gum arabic, carrageenan, guar gum, tamarind gum, or pectin) and evaluated the swelling degree, tablet hardness, friability, disintegration time, and adhesive properties. All tablets had a swelling degree of about 1 mm, a hardness of over 13 N, and a friability degree of <1%. Tablets containing gum arabic and tamarind gum had disintegration times of 30 s or less and satisfied requirements as orally disintegrating tablets. This could be attributed to their high void contents, which allowed for water penetration. The adhesive properties and particle retention ratios were highest in ODTTs containing tamarind gum, which was thought to be caused by the rapid disintegration and high viscosity of the tamarind gum itself. When we investigated changing the mass fraction of tamarind gum, we found 1 w/w% was most suitable for rapid disintegration and high adhesiveness. The ODTTs containing 1 w/w% tamarind gum showed significant growth inhibition towards Streptococcus mutans. Therefore, microwave irradiation technology and addition of tamarind gum could be used to manufacture muco-adhesive orally disintegrating tablets for oral care.

Abstract
OBJECTIVES Aspiration pneumonia is a leading cause of death among older patients; however, little is known about the long-term mortality in aspiration pneumonia. The purpose of this study was to evaluate long-term mortality and its associated factors in patients with aspiration pneumonia. DESIGN Retrospective cohort study. SETTING AND PARTICIPANTS In total, 550 patients with aspiration pneumonia (median age: 78.0 years, 66.4% male) with compatible clinical symptoms and chest computed tomography images were enrolled at a single tertiary center from 2006 to 2016. MEASURES The 1-, 3-, and 5-year mortality rates were evaluated for all patients. The prognostic factors for 1-year and 5-year mortality were also evaluated using Cox proportional hazard models. RESULTS A total of 441 (80.2%) patients died during a median follow-up of 50.7 weeks. The 1-, 3-, and 5-year mortality rates were 49.0%, 67.1%, and 76.9%, respectively. Multivariate analysis identified 5 risk factors for 1-year mortality of male sex [hazard ratio (HR) 1.533, P = .003], low body mass index (HR 0.934, P = .002), hypoalbuminemia, anemia (0.973, P = .032), and mechanical ventilation (HR 2.052, P < .001), which were also independent prognostic factors for 5-year mortality. During the follow-up period, 133 (24.2%) patients experienced recurrent aspiration pneumonia. However, Kaplan-Meier analysis showed no significant differences in survival curves between patients with single and recurrent aspiration pneumonia (P = .371). CONCLUSIONS/IMPLICATIONS Long-term prognosis of aspiration pneumonia was poor as a result of underlying morbidity instead of the aspiration pneumonia itself. Our findings suggest that prognostic indices for patients with aspiration pneumonia including the patient's underlying conditions should be devised.

Abstract
KEY POINTS Afferents carried by the superior laryngeal nerve play a primary role in the initiation of laryngeal mechanically evoked swallows in anaesthetized rats. Amiloride and its analogues inhibit swallowing evoked by mechanical stimulation, but not swallowing evoked by chemical and electrical stimulation. The epithelial sodium channel is probably involved in the initiation of laryngeal mechanically evoked swallows. ABSTRACT The swallowing reflex plays a critical role in airway protection. Because impaired laryngeal mechanosensation is associated with food bolus aspiration, it is important to know how the laryngeal sensory system regulates swallowing initiation. This study was performed to clarify the neuronal mechanism of mechanically evoked swallows. Urethane-anaesthetized Sprague-Dawley male rats were used. A swallow was identified by activation of the suprahyoid and thyrohyoid muscles on electromyography. The swallowing threshold was measured by von Frey filament and electrical stimulation of the larynx. The number of swallows induced by upper airway distension and capsaicin application (0.03 nmol, 3 μl) to the vocal folds was counted. The effects of topical application (0.3-30 nmol, 3 μl) of the epithelial sodium channel (ENaC) blocker amiloride and its analogues (benzamil and dimethylamiloride), acid-sensing ion channel (ASIC) inhibitors (mambalgine-1 and diminazene) and gadolinium to the laryngeal mucosa on swallowing initiation were evaluated. A nerve transection study indicated that afferents carried by the superior laryngeal nerve play a primary role in the initiation of laryngeal mechanically evoked swallows. The mechanical threshold of swallowing was increased in a dose-dependent manner by amiloride and its analogues and gadolinium, but not by ASIC inhibitors. The number of swallows by upper airway distension was significantly decreased by benzamil application. However, the initiation of swallows evoked by capsaicin and electrical stimulation was not affected by benzamil application. We speculate that the ENaC is involved in the initiation of laryngeal mechanically evoked swallows.

Abstract
Pneumonia remains the main cause of morbidity and mortality from infectious diseases in the world. The important reason for the increased global mortality is the impact of pneumonia on chronic diseases especially in the elderly population and the virulence factors of the causative microorganisms. Because elderly individuals present with comorbidities, particular attention should be paid for multidrug-resistant pathogens. Streptococcus pneumoniae remains the most frequently encountered pathogen. Enteric gram-negative rods, as well as anaerobes, should be considered in patients with aspiration pneumonia. Interventions for modifiable risk factors will reduce the risk of this infection. The adequacy of the initial antimicrobial therapy and determination of patients’ follow-up place is a key factor for prognosis. Also, vaccination is one of the most important preventive measures. In this section it was focused on several aspects, including the atypical presentation of pneumonia in the elderly, the methods to evaluate the severity of illness, the appropriate take care place and the management with prevention strategies.

[PMID: 30556343 DOI: 10.1111/ggi.13559] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2018] [Revised: 09/09/2018] [Accepted: 10/08/2018] [Indexed: 01/08/2023]
Abstract
AIM The present study aimed to investigate the risk factors and prognostic implications of aspiration pneumonia in older hip fracture patients. METHODS A total of 394 female and 125 male hip fracture patients aged ≥60 years who underwent surgery between 2015 and 2018 were retrospectively analyzed. To identify risk factors of aspiration pneumonia, demographic factors, the American Society of Anesthesiologists classification, past medical history, known risk factors of aspiration and factors associated with surgery were compared between the aspiration pneumonia group and the control group. Regression analysis was also carried out. To assess the prognostic implications of aspiration pneumonia, hospital stay, frequency of the intensive care unit admission and in-hospital mortality rates were compared between groups. RESULTS Aspiration pneumonia was diagnosed in 8.8% of the hip fracture patients. Increased age, low body mass index, malnutrition, longer duration of surgery and delayed surgery were identified as risk factors of aspiration pneumonia. Regarding prognostic implications, hospital stay, the frequency of intensive care unit care and in-hospital mortality rates were significantly higher in the aspiration pneumonia group (P < 0.001, <0.001 and 0.001, respectively). CONCLUSIONS Older hip fracture patients with aspiration pneumonia showed worse prognostic outcome compared with patients without aspiration pneumonia. Longer duration of surgery and delayed surgery, as well as patient characteristics including increased age, low body mass index and malnutrition were identified as risk factors for aspiration pneumonia. Therefore, surgeons should try to reduce the operation time and the time interval between injury and surgery when treating older patients for hip fractures. Geriatr Gerontol Int 2019; 19: 119-123.

Abstract
This study aimed i) to investigate about items with high relevance for aspiration pneumonia during hospitalization among cases evaluated using Diagnosis Procedure Combination data, and ii) to determine whether the concern factors for aspiration pneumonia during hospitalization were exacerbated with the trend of the time. The Diagnosis Procedure Combination data were gathered from 2010 through to 2015 with 63,390 cases at Saga University Hospital. The occurrence of concern factors of aspiration pneumonia during hospitalization were compared in the two time periods set (2010-2012 and 2013-2015). The concern factors included: male, age, dysphagia at admission and during hospitalization, use and days in the emergency care unit or high care unit, use of the intensive care unit, and use of an ambulance. Age, dysphagia, and use of the intensive care unit were time-dependently exacerbated. The incidence of aspiration pneumonia during hospitalization in hospitalized cases did not differ between years 2010-2012 and 2013-2015. Aspiration pneumonia during hospitalization complicated with surgery and number days in the emergency care unit or high care unit diminished in years 2013-2015. Despite an increased concern of aspiration pneumonia during hospitalization, the complication rate of aspiration pneumonia during hospitalization did not increase.

Abstract
This narrative review summarises the benefits, risks and appropriate use of acid-suppressing drugs (ASDs), proton pump inhibitors and histamine-2 receptor antagonists, advocating a rationale balanced and individualised approach aimed to minimise any serious adverse consequences. It focuses on current controversies on the potential of ASDs to contribute to infections-bacterial, parasitic, fungal, protozoan and viral, particularly in the elderly, comprehensively and critically discusses the growing body of observational literature linking ASD use to a variety of enteric, respiratory, skin and systemic infectious diseases and complications (Clostridium difficile diarrhoea, pneumonia, spontaneous bacterial peritonitis, septicaemia and other). The proposed pathogenic mechanisms of ASD-associated infections (related and unrelated to the inhibition of gastric acid secretion, alterations of the gut microbiome and immunity), and drug-drug interactions are also described. Both probiotics use and correcting vitamin D status may have a significant protective effect decreasing the incidence of ASD-associated infections, especially in the elderly. Despite the limitations of the existing data, the importance of individualised therapy and caution in long-term ASD use considering the balance of benefits and potential harms, factors that may predispose to and actions that may prevent/attenuate adverse effects is evident. A six-step practical algorithm for ASD therapy based on the best available evidence is presented.

Abstract
Swallowing pressure generation is important to ensure safe transport of an ingested bolus without aspiration or leaving residue in the pharynx. To clarify the mechanism, we measured swallowing pressure at the oropharynx (OP), upper esophageal sphincter (UES), and cervical esophagus (CE) using a specially designed manometric catheter in anesthetized rats. A swallow, evoked by punctate mechanical stimulation to the larynx, was identified by recording activation of the suprahyoid and thyrohyoid muscles using electromyography (EMG). Areas under the curve of the swallowing pressure at the OP, UES, and CE from two trials indicated high intrasubject reproducibility. Effects of transecting the hypoglossal nerve (12N) and recurrent laryngeal nerve (RLN) on swallowing were investigated. Following bilateral hypoglossal nerve transection (Bi-12Nx), OP pressure was significantly decreased, and time intervals between peaks of thyrohyoid EMG bursts and OP pressure were significantly shorter. Decreased OP pressure and shortened times between peaks of thyrohyoid EMG bursts and OP pressure following Bi-12Nx were significantly increased and longer, respectively, after covering the hard and soft palates with acrylic material. UES pressure was significantly decreased after bilateral RLN transection compared with that before transection. These results suggest that the 12N and RLN play crucial roles in OP and UES pressure during swallowing, respectively. We speculate that covering the palates with a palatal augmentation prosthesis may reverse the reduced swallowing pressure in patients with 12N or tongue damage by the changes of the sensory information and of the contact between the tongue and a palates. NEW & NOTEWORTHY Hypoglossal nerve transection reduced swallowing pressure at the oropharynx. Covering the hard and soft palates with acrylic material may reverse the reduced swallowing function caused by hypoglossal nerve damage. Recurrent laryngeal nerve transection reduced upper esophageal sphincter negative pressure during swallowing.

Abstract
Objective To elucidate factors, other than those clinical, precipitating the risk of aspiration in hospitalized patients. Design The Critical Incident Technique was adopted for this study in 2015. Setting Three departments located in two academic hospitals in the northeast of Italy, equipped with 800 and 1500 beds, respectively. Participants A purposeful sample of 12 registered nurses (RN), all of whom (i) had reported one or more episodes of aspiration during the longitudinal survey, (ii) had worked ≥3 years in the department, and (iii) were willing to participate, were included. Main Outcome Measure(s) Antecedent factors involved in episodes of aspiration as experienced by RNs were collected through an open-ended interview, and qualitatively analysed. Results In addition to clinical factors, other factors interacting with each other may precipitate the risk of aspiration episodes during hospitalization: at the nursing care level (misclassifying patients, transferring tasks to other healthcare professionals and standardizing processes to remove potential threats); at the family level (misclassifying patients, dealing with the cultural relevance of eating) and at the environmental level (positioning the patient, managing time pressures, distracting patient while eating, dealing with food consistency and irritating oral medication). Conclusions At the hospital level, an adequate nursing workforce and models of care delivery, as well as time for initial and continuing patient and family assessment are required. At the unit level, patient-centred models of care aimed at reducing care standardization are also recommended; in addition, nursing, family and environmental factors should be recorded in the incident reports documenting episodes of aspiration.

Abstract
INTRODUCTION Community-acquired pneumonia (CAP) is an increasing problem in the elderly that is associated with elevated morbidity and mortality. Given the expected increased life expectancy, this problem is only likely to worsen, so it has been considered that treatment effects must be examined separately in elderly adults with CAP. Areas covered: In this narrative review, we give an update of the available data of antibiotics for elderly patients with CAP. Clinical features, drug pharmacokinetics and pharmacodynamics, adverse effects, and outcomes differ in CAP depending on patient age. Older age, for example, can affect the effect of specific antibiotic regimens on important CAP clinical outcomes. Current guidelines do not offer specific recommendations for the management of CAP in elderly patients. Expert opinion: Most of our knowledge about the treatment of CAP in elderly patients has been gained from studies in young populations. However, elderly patients with CAP deserve special attention because there are several factors in this population that could influence their response to antibiotic regimens in CAP.

Abstract
[Purpose] The purpose of this investigation was to compare the activities of the abdominal muscles and peak expiratory flow between forced vital capacity and fast expiration exercise. [Subjects and Methods] Fifteen healthy male participated in this study. Peak expiratory flow and electromyographic activities of the rectus abdominis, external oblique, and internal oblique/transversus abdominis muscles were measured during forced vital capacity and fast expiration exercise and then peak amplitude and its appearance time were obtained. [Results] Peak expiratory flow values were significantly higher during fast expiration exercise than during forced vital capacity. The internal oblique/transversus abdominis muscles showed significantly higher peak amplitude during fast expiration exercise than during forced vital capacity. However, there were no significant differences between forced vital capacity and fast expiration exercise in the rectus abdominis and external oblique muscles. There was no difference in the appearance time of the peak amplitude between forced vital capacity and fast expiration exercise in any muscle. [Conclusion] Fast expiration exercise might be beneficial for increasing expiratory speed and neuromuscular activation of the internal oblique/transversus abdominis muscles compared to forced vital capacity. These findings could be considered when recommending a variation of expiratory muscle strength training as part of pulmonary rehabilitation programs.

Abstract
Aspiration pneumonia is a common disease that frequently occurs in elderly patients. Most patients with aspiration pneumonia have swallowing disability and develop hospital‐acquired disability. Frequently, patients have difficulty returning home, and they often require long‐term hospitalization. Recently, the effectiveness of rehabilitative management including physical, pulmonary, and dysphagia rehabilitation for aspiration pneumonia was reported. Several studies showed that early rehabilitation was associated with reduced mortality and early hospital discharge after aspiration pneumonia. Unnecessary “nil by mouth” directives associated with aspiration pneumonia at hospital admission resulted in adverse effects, including decline in swallowing ability and prolonged treatment duration. Rehabilitative management combined with appropriate nutrition is recommended to improve clinical outcomes, including physical and swallowing function in geriatric patients with aspiration pneumonia.

Abstract
Globally, pneumonia is a serious public health concern and a major cause of mortality and morbidity. Despite advances in antimicrobial therapies, microbiological diagnostic tests and prevention measures, pneumonia remains the main cause of death from infectious disease in the world. An important reason for the increased global mortality is the impact of pneumonia on chronic diseases, along with the increasing age of the population and the virulence factors of the causative microorganism. The increasing number of multidrug-resistant bacteria, difficult-to-treat microorganisms, and the emergence of new pathogens are a major problem for clinicians when deciding antimicrobial therapy. A key factor for managing and effectively guiding appropriate antimicrobial therapy is an understanding of the role of the different causative microorganisms in the etiology of pneumonia, since it has been shown that the adequacy of initial antimicrobial therapy is a key factor for prognosis in pneumonia. Furthermore, broad-spectrum antibiotic therapies are sometimes given until microbiological results are available and de-escalation cannot be performed quickly. This review provides an overview of microbial etiology, resistance patterns, epidemiology and microbial diagnosis of pneumonia.

Abstract
Aspiration pneumonia is thought to be associated with a poor outcome in patients with community acquired pneumonia (CAP). However, there has been no systematic review regarding the impact of aspiration pneumonia on the outcomes in patients with CAP. This review was conducted using the MOOSE guidelines: Patients: patients defined CAP. Exposure: aspiration pneumonia defined as pneumonia in patients who have aspiration risk. Comparison: confirmed pneumonia in patients who were not considered to be at high risk for oral aspiration. Outcomes: mortality, hospital readmission or recurrent pneumonia. Three investigators independently identified published cohort studies from PubMed, CENTRAL database, and EMBASE. Nineteen studies were included for this systematic review. Aspiration pneumonia increased in-hospital mortality (relative risk, 3.62; 95% CI, 2.65–4.96; P < 0.001, seven studies) and 30-day mortality (3.57; 2.18–5.86; P < 0.001, five studies). In contrast, aspiration pneumonia was associated with decreased ICU mortality (relative risk, 0.40; 95% CI, 0.26–0.60; P < 0.00001, four studies). Although there are insufficient data to perform a meta-analysis on long-term mortality, recurrent pneumonia, and hospital readmission, the few reported studies suggest that aspiration pneumonia is also associated with these poor outcomes. In conclusion, aspiration pneumonia was associated with both higher in-hospital and 30-day mortality in patients with CAP outside ICU settings.
