Clinical characteristics of and risk factors for secondary bloodstream infection after pneumonia among patients infected with methicillin-resistant Staphylococcus aureus. Heliyon 2022; 8:e11978. [PMID: 36506352 PMCID: PMC9732304 DOI: 10.1016/j.heliyon.2022.e11978] [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: 06/15/2022] [Revised: 10/29/2022] [Accepted: 11/23/2022] [Indexed: 12/04/2022] Open
Abstract
Purpose To investigate the clinical features and risk factors for methicillin-resistant Staphylococcus aureus (MRSA) pneumonia (MP) with secondary MRSA bloodstream infections (MRSA-BSI) (termed MP-BSI) compared with MP alone and to study the incidence of MP-BSI among patients with MP. Methods This was a retrospective, single-center study with clinical data derived from previous medical records. The cases were divided into groups: MP alone and MP-BSI. The determination of independent risk factors for MP-BSI relied on logistic regression analysis. Additionally, the crude outcomes were compared. Results A total of 435 patients with MP were recruited, with 18.9% (82/435) having MP-BSI. The median age was 62 (interquartile range, 51,72) years, and 74.5% of the patients were male. Multivariate analysis revealed that immunosuppression, community-acquired MP (CA-MP), time from initial to targeted antibiotic use, high Sequential Organ Failure Assessment (SOFA) score, increased respiratory rate, and elevated γ-GT level (all p < 0.05) were independent risk factors for MP-BSI, while targeted treatment with linezolid was a protective factor. Patients with MP-BSI had a longer duration of hospitalization (median days, 27.5 vs. 19, p = 0.001), a higher 28-day mortality rate (24.4% vs. 11.0%, p = 0.001), and a higher in-hospital mortality rate (26.8% vs. 14.7%, p = 0.009) than those with MP alone. Conclusion Secondary MRSA-BSI among patients with MP is not rare. Immunosuppression, CA-MP, time from initial to targeted antibiotic use, high SOFA score, increased respiratory rate and elevated γ-GT level are all independent risk factors for MP-BSI; however, linezolid, as a targeted antibiotic, is a protective factor. Moreover, patients with MP may have worse clinical outcomes when they develop MRSA-BSI.

Abstract
BACKGROUND Pneumonia in residents of nursing homes can be termed nursing home-acquired pneumonia (NHAP). NHAP is one of the most common infections identified in nursing home residents and has the highest mortality of any infection in this population. NHAP is associated with poor oral hygiene and may be caused by aspiration of oropharyngeal flora into the lung. Oral care measures to remove or disrupt oral plaque might reduce the risk of NHAP. This is the first update of a review published in 2018. OBJECTIVES To assess effects of oral care measures for preventing nursing home-acquired pneumonia in residents of nursing homes and other long-term care facilities. SEARCH METHODS An information specialist searched CENTRAL, MEDLINE, Embase, one other database and three trials registers up to 12 May 2022. We also used additional search methods to identify published, unpublished and ongoing studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) that evaluated the effects of oral care measures (brushing, swabbing, denture cleaning mouthrinse, or combination) in residents of any age in nursing homes and other long-term care facilities. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed search results, extracted data, and assessed risk of bias in the included studies. We contacted study authors for additional information. We pooled data from studies with similar interventions and outcomes. We reported risk ratios (RRs) for dichotomous outcomes, mean differences (MDs) for continuous outcomes, and hazard ratios (HRs) or incidence rate ratio (IRR) for time-to-event outcomes, using random-effects models. MAIN RESULTS We included six RCTs (6244 participants), all of which were at high risk of bias. Three studies were carried out in Japan, two in the USA, and one in France. The studies evaluated one comparison: professional oral care versus usual oral care. We did not include the results from one study (834 participants) because it had been stopped at interim analysis. Consistent results from five studies, with 5018 participants, provided insufficient evidence of a difference between professional oral care and usual (simple, self-administered) oral care in the incidence of pneumonia. Three studies reported HRs, one reported IRRs, and one reported RRs. Due to the variation in study design and follow-up duration, we decided not to pool the data. We downgraded the certainty of the evidence for this outcome by two levels to low: one level for study limitations (high risk of performance bias), and one level for imprecision. There was low-certainty evidence from meta-analysis of two individually randomised studies that professional oral care may reduce the risk of pneumonia-associated mortality compared with usual oral care at 24 months' follow-up (RR 0.43, 95% CI 0.25 to 0.76, 454 participants). Another study (2513 participants) reported insufficient evidence of a difference for this outcome at 18 months' follow-up. Three studies measured all-cause mortality and identified insufficient evidence of a difference between professional and usual oral care at 12 to 30 months' follow-up. Only one study (834 participants) measured the adverse effects of the interventions. The study identified no serious events and 64 non-serious events, the most common of which were oral cavity disturbances (not defined) and dental staining. No studies evaluated oral care versus no oral care. AUTHORS' CONCLUSIONS Although low-certainty evidence suggests that professional oral care may reduce mortality compared to usual care when measured at 24 months, the effect of professional oral care on preventing NHAP remains largely unclear. Low-certainty evidence was inconclusive about the effects of this intervention on incidence and number of first episodes of NHAP. Due to differences in study design, effect measures, follow-up duration, and composition of the interventions, we cannot determine the optimal oral care protocol from current evidence. Future trials will require larger samples, robust methods that ensure low risk of bias, and more practicable interventions for nursing home residents.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:13731. [PMID: 36360610 PMCID: PMC9654310 DOI: 10.3390/ijerph192113731] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 10/18/2022] [Accepted: 10/19/2022] [Indexed: 06/16/2023]
Abstract
Appropriate oral health care, depending on oral assessments, reduces the onset of pneumonia. However, the relationship between risk evaluation using an oral assessment tool and pneumonia in residents of long-term care facilities has not been fully elucidated. In the present study, we aim to examine the relationship between the total scores of the Oral Assessment Guide (OAG) and the incidence of pneumonia after a one-year baseline study of residents in long-term care facilities. The settings for sampling include nine long-term care facilities in Hokkaido. At baseline, there were 267 study subjects. A total of 72 individuals dropped out and 11 individuals met the exclusion criteria. Therefore, the subject sample included 184 individuals. Among the subjects included in our analyses, eight individuals developed pneumonia (six males and two females). A multiple logistic regression analysis was performed with the risk factors for developing pneumonia. Evaluations were performed based on the odds ratio (OR) and 95% confidence interval (CI). We observed that the OR for pneumonia onset was 2.29 (CI: 1.27-4.14) after being adjusted for pneumonia risk factors. Therefore, it was suggested that the total scores of the OAG could be used to screen for the risk of pneumonia onset in residents of long-term care and welfare facilities.

Restrictive type and infectious complications might predict nadir hematological values among individuals with anorexia nervosa during the refeeding period: a retrospective study. J Eat Disord 2022; 10:64. [PMID: 35513879 PMCID: PMC9074196 DOI: 10.1186/s40337-022-00586-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Accepted: 05/01/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Although hematological abnormalities in patients with anorexia nervosa have been documented, the mechanisms involved have not been fully clarified, especially during the refeeding period when hematological values further decrease after admission prior to improving. Here we address potential mechanisms underlying the hematological abnormalities of inpatients with anorexia nervosa during the refeeding period. METHODS We recruited patients from 101 admissions corresponding to 55 individual patients with anorexia nervosa with severe malnutrition (body mass index, 13.4 ± 3.4) from the neuropsychiatry unit in Ashikaga Red Cross Hospital during the period from October 1999 to March 2018. We analyzed three hematological cell measures, i.e., hemoglobin, white cell count, and platelet count, to determine their levels at admission and their lowest levels during the refeeding period and calculated the percent decrease in those values from admission to the nadir levels. We analyzed each measure using a general mixed model with explanatory variables, including data upon admission and a treatment-related indicator, i.e., energy intake. RESULTS The initial hemoglobin value of 12.1 ± 2.7 g/dl decreased by 22.3% to 9.4 ± 2.5 g/dl; the initial white cell count was 5387 ± 3474/μl, which decreased by 33.6% to 3576 ± 1440/μl; the initial platelet count of 226 ± 101 × 103/μl decreased by 24.3% to 171 ± 80 × 103/μl. All nadir levels were observed during the refeeding period from the fifth to tenth day of hospitalization. Significant correlations among the three hematological cell measures, particularly at the nadir levels, were found. Of note, 41.7% of our patients who received red blood cell transfusion during hospitalization showed normal hemoglobin levels upon admission. The anorexia nervosa restrictive type was associated with a lower nadir level of white blood cell count. Infectious complications were related to a lower nadir level of hemoglobin and a greater percent decrease in hemoglobin level as well as to the need for red blood cell transfusion. CONCLUSIONS Nadir hematological cell measures of inpatients with anorexia nervosa might be predicted by the restrictive type and infectious complications. The anorexia nervosa restrictive type was associated with further decrease in hematological values during the refeeding period.

Abstract
Pseudomonas aeruginosa (PA), a non-lactose-fermenting gram-negative bacillus, is a common cause of nosocomial infections in critically ill or debilitated patients, particularly ventilator-associated pneumonia (VAP), and infections of urinary tract, intra-abdominal, wounds, skin/soft tissue, and bloodstream. PA rarely affects healthy individuals, but may cause serious infections in patients with chronic structural lung disease, comorbidities, advanced age, impaired immune defenses, or with medical devices (e.g., urinary or intravascular catheters, foreign bodies). Treatment of pseudomonal infections is difficult, as PA is intrinsically resistant to multiple antimicrobials, and may acquire new resistance determinants even while on antimicrobial therapy. Mortality associated with pseudomonal VAP or bacteremias is high (> 35%) and optimal therapy is controversial. Over the past three decades, antimicrobial resistance (AMR) among PA has escalated globally, via dissemination of several international multidrug resistant "epidemic" clones. We discuss the importance of PA as a cause of pneumonia including health care-associated pneumonia, hospital-acquired pneumonia, VAP, the emergence of AMR to this pathogen, and approaches to therapy (both empirical and definitive).

Abstract
IMPORTANCE Older adults residing in long-term care facilities (LTCFs) are at a high risk of being infected with respiratory viruses, such as influenza and respiratory syncytial virus (RSV). Although these infections commonly have many cardiorespiratory sequelae, the national burden of influenza- and RSV-attributable cardiorespiratory events remains unknown for the multimorbid and vulnerable LTCF population. OBJECTIVE To estimate the incidence of cardiorespiratory hospitalizations that were attributable to influenza and RSV among LTCF residents and to quantify the economic burden of these hospitalizations on the US health care system by estimating their associated cost and length of stay. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study used national Medicare Provider Analysis and Review inpatient claims and Minimum Data Set clinical assessments for 6 respiratory seasons (2011-2017). Long-stay residents of LTCFs were identified as those living in the facility for at least 100 days (index date), aged 65 years or older, and with 6 months of continuous enrollment in Medicare Part A were included. Follow-up occurred from the resident's index date until the first hospitalization, discharge from the LTCF, disenrollment from Medicare, death, or the end of the study. Residents could re-enter the sample; thus, long-stay episodes of care were identified. Data analysis was performed between January 1 and September 30, 2020. EXPOSURES Seasonal circulating pandemic 2009 influenza A(H1N1), human influenza A(H3N2), influenza B, and RSV. MAIN OUTCOMES AND MEASURES Cardiorespiratory hospitalizations (eg, asthma exacerbation, heart failure) were identified using primary diagnosis codes. Influenza- and RSV-attributable cardiorespiratory events were estimated using a negative binomial regression model adjusted for weekly circulating influenza and RSV testing data. Length of stay and costs of influenza- and RSV-attributable events were then estimated. RESULTS The study population comprised 2 909 106 LTCF residents with 3 138 962 long-stay episodes and 5 079 872 person-years of follow-up. Overall, 10 939 (95% CI, 9413-12 464) influenza- and RSV-attributable cardiorespiratory events occurred, with an incidence of 215 (95% CI, 185-245) events per 100 000 person-years. The cost of influenza- and RSV-attributable cardiorespiratory events was $91 055 393 (95% CI, $77 885 316-$104 225 470), and the length of stay was 56 858 (95% CI, 48 757-64 968) days. CONCLUSIONS AND RELEVANCE This study found that many cardiorespiratory hospitalizations among LTCF residents in the US were attributable to seasonal influenza and RSV. To minimize the burden these events place on the health care system and residents of LTCFs and to prevent virus transmission, additional preventive measures should be implemented.

Incidence of Antibiotic Treatment Failure in Patients with Nursing Home-Acquired Pneumonia and Community Acquired Pneumonia. Infect Dis Rep 2021; 13:33-44. [PMID: 33466353 PMCID: PMC7838805 DOI: 10.3390/idr13010006] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 12/12/2020] [Accepted: 12/14/2020] [Indexed: 01/05/2023] Open
Abstract
Purpose: Nursing home-acquired pneumonia (NHAP) patients are at higher risk of multi-drug resistant infection (MDR) than those with community-acquired pneumonia (CAP). Recent evidence suggests a single risk factor for MDR does not accurately predict the need for broad-spectrum antibiotics. The goal of this study was to compare the rate antibiotic failure between NHAP and CAP patients. Methods: Demographic characteristics, co-morbidities, clinical and laboratory variables, antibiotic therapy, and mortality data were collected retrospectively for all patients with pneumonia admitted to an Internal Medicine Service between April 2017 and April 2018. Results: In total, 313 of 556 patients had CAP and 243 had NHAP. NHAP patients were older, and were more likely to be dependent, to have recent antibiotic use, and to experience treatment failure (odds ratio (OR) 1.583; 95% CI 1.102–2.276; p = 0.013). In multivariate analysis, patient’s origin did not predict treatment failure (OR 1.083; 95% CI 0.726–1.616; p = 0.696). Discussion: Higher rates of antibiotic failure and mortality in NHAP patients were explained by the presence of other risk factors such as comorbidities, more severe presentation, and age. Admission from a nursing home is not a sufficient condition to start broader-spectrum antibiotics.

Abstract
Background Elevated Staphylococcus aureus and oral bacterial concentrations are known to correlate with pneumonia hospitalization in nursing home residents. However, the effects of a professional oral care intervention on these factors remain unclear. The aims of this quasi-experimental study were to compare bacterial concentrations in saliva and sputum, oral health status, distribution of Staphylococcus aureus, and pneumonia status before and after a professional oral care intervention. Methods A purposive sample of residents from two nursing homes was divided into an intervention group that received a weekly professional oral care intervention and a control group. Oral bacterial concentration was determined by real-time polymerase chain reaction. The Staphylococcus aureus distribution was determined by bacterial culture and matrix-assisted laser desorption/ionization–time of flight mass spectrometry. After data collection, a statistical analysis was performed to evaluate the effect of the intervention. Results Most residents were unconscious (80%), and most had a history of pneumonia (76%). Baseline demographic data did not significantly differ between the two groups. After the intervention, the intervention group had significant improvements in plaque index (1.66 ± 0.78 vs. 0.94 ± 0.64, p < 0.01), gingival index (2.36 ± 0.76 vs. 1.65 ± 0.83, p < 0.01), tongue coating index (0.96 ± 1.10 vs. 0.16 ± 0.47, p < 0.01), distribution of Staphylococcus aureus in salivary samples (11.11 ± 14.47% vs. 1.74 ± 3.75%, p = 0.02), and salivary bacterial concentration ([4.27 ± 3.65] × 105 vs. [0.75 ± 1.20] × 105, p < 0.01). Sputum bacterial concentration did not significantly differ. The intervention group also had a significantly lower annual prevalence of pneumonia hospitalization (1.24 ± 1.51 vs. 0.48 ± 0.59, p = 0.01), especially in residents whose salivary bacterial concentration exceeded the median. However, the duration of pneumonia hospitalization did not significantly differ between the two groups. Conclusion A professional oral care intervention in nursing home residents can improve oral health, reduce levels of salivary bacteria and Staphylococcus aureus, and decrease the annual prevalence of pneumonia hospitalization.

Non-ventilator health care-associated pneumonia (NV-HAP): Long-term care. Am J Infect Control 2020; 48:A14-A16. [PMID: 32331558 DOI: 10.1016/j.ajic.2020.03.007] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2020] [Accepted: 03/02/2020] [Indexed: 12/14/2022]
Abstract
Nonventilator health care-associated pneumonia (NV-HAP) is costly and preventable with significant impact on patient morbidity and mortality. This chapter outlines the increased risk of NV-HAP among individuals residing in long-term care facilities and the incidence of pneumonia in this health care setting which accounts for up to 18% of all persons admitted to acute care hospital for pneumonia. A description of prevention strategies with detail on modifiable and Nonmodifiable risk factors for acquiring pneumonia are presented along with the need for a robust interdisciplinary team and approach for this vulnerable population. In addition, the lack of active surveillance and infection prevention expertise may result in the spread of pathogens that can cause NVHAP outbreaks.

Abstract
Physical restraint in clinical settings can lead to potentially lethal complications. Although this is a life-and-death issue, no comprehensive large-scale study relating medical complications to physical restraint has yet been performed. The 1308 psychiatric inpatients in our retrospective cohort study were categorized into two groups: a physical restraint group (those who had been subjected to physical restraint while hospitalized; n = 110) and a non-physical restraint group (those never subjected to physical restraint; n = 1198). We assessed differences between the two groups with respect to the occurrence of medical complications subsequent to restraint. To control for potentially confounding factors, linear discriminant regression analysis was used to identify whether physical restraint itself affected the occurrence of medical complications. The physical restraint group had a higher risk for deep vein thrombosis (P < .01, OR = 6.0, 95%CI: 2.4-13.9) and aspiration pneumonia (P < .01, OR = 4.1, 95%CI: 2.1-7.6) when compared with the non-physical restraint group. Even after controlling for potentially confounding factors, physical restraint substantially raised the risk of deep vein thrombosis and aspiration pneumonia (P < .01, P = .01, respectively). Although this study population was derived from a single psychiatric unit, physical restraint may lead to serious medical conditions. To avoid this unwanted consequence, the use of physical restraint should be minimized and physical therapy is highly recommended.

Abstract
Radiation therapy requires repeated anesthetic administration to patients who often have multiple comorbidities contributing to an increased rate of anesthetic complications such as pneumonia. This is a retrospective observational study in which data were collected from 146 medical records of dogs receiving repeat anesthesia for radiation treatment from prior to management changes and compared to data from 149 cases treated after completion of management changes. The objective was to determine if changes in case management protocol that were put in place decreased the risk of pneumonia development among these patients. Management changes that were made included the following: decrease in anticholinergic and pure-mu opioid use, change in positioning during intubation and recovery, prophylactic treatment of nausea, timing of cuff inflation and deflation, and aseptic handling of intubation equipment. There was a significant association between diagnosis of pneumonia and the following: pre- vs. post-changes to protocol, presence of a neurologic tumor, presence of respiratory disease, presence of megaesophagus, and number of radiation fractions completed. Diagnosis of pneumonia did not vary significantly by age group, body weight category, or sex. In a multivariable logistic regression model that controlled for the effects of the three concurrent diseases and fractions completed, the odds of being diagnosed with pneumonia were approximately 10 times greater among dogs anesthetized prior to management changes (odds ratio = 9.9, 95% CI = 2.0-48.7, P = 0.005).

Abstract
BACKGROUND Pneumonia occurring in residents of long-term care facilities and nursing homes can be termed 'nursing home-acquired pneumonia' (NHAP). NHAP is the leading cause of mortality among residents. NHAP may be caused by aspiration of oropharyngeal flora into the lung, and by failure of the individual's defence mechanisms to eliminate the aspirated bacteria. Oral care measures to remove or disrupt oral plaque might be effective in reducing the risk of NHAP. OBJECTIVES To assess effects of oral care measures for preventing nursing home-acquired pneumonia in residents of nursing homes and other long-term care facilities. SEARCH METHODS Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 15 November 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2017, Issue 10), MEDLINE Ovid (1946 to 15 November 2017), and Embase Ovid (1980 to 15 November 2017) and Cumulative Index to Nursing and Allied Health Literature (CINAHL; 1937 to 15 November 2017). The US National Institutes of Health Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. We also searched the Chinese Biomedical Literature Database, the China National Knowledge Infrastructure, and the Sciencepaper Online to 20 November 2017. SELECTION CRITERIA We included randomised controlled trials (RCTs) that evaluated the effects of oral care measures (brushing, swabbing, denture cleaning mouthrinse, or combination) in residents of any age in nursing homes and other long-term care facilities. DATA COLLECTION AND ANALYSIS At least two review authors independently assessed search results, extracted data, and assessed risk of bias in the included studies. We contacted study authors for additional information. We pooled data from studies with similar interventions and outcomes. We reported risk ratio (RR) for dichotomous outcomes, mean difference (MD) for continuous outcomes, and hazard ratio (HR) for time-to-event outcomes, using random-effects models. MAIN RESULTS We included four RCTs (3905 participants), all of which were at high risk of bias. The studies all evaluated one comparison: professional oral care versus usual oral care. We did not pool the results from one study (N = 834 participants), which was stopped at interim analysis due to lack of a clear difference between groups.We were unable to determine whether professional oral care resulted in a lower incidence rate of NHAP compared with usual oral care over an 18-month period (hazard ratio 0.65, 95% CI 0.29 to 1.46; one study, 2513 participants analysed; low-quality evidence).We were also unable to determine whether professional oral care resulted in a lower number of first episodes of pneumonia compared with usual care over a 24-month period (RR 0.61, 95% CI 0.37 to 1.01; one study, 366 participants analysed; low-quality evidence).There was low-quality evidence from two studies that professional oral care may reduce the risk of pneumonia-associated mortality compared with usual oral care at 24-month follow-up (RR 0.41, 95% CI 0.24 to 0.72, 507 participants analysed).We were uncertain whether or not professional oral care may reduce all-cause mortality compared to usual care, when measured at 24-month follow-up (RR 0.55, 95% CI 0.27 to 1.15; one study, 141 participants analysed; very low-quality evidence).Only one study (834 participants randomised) measured adverse effects of the interventions. The study identified no serious events and 64 non-serious events, the most common of which were oral cavity disturbances (not defined) and dental staining.No studies evaluated oral care versus no oral care. AUTHORS' CONCLUSIONS Although low-quality evidence suggests that professional oral care could reduce mortality due to pneumonia in nursing home residents when compared to usual care, this finding must be considered with caution. Evidence for other outcomes is inconclusive. We found no high-quality evidence to determine which oral care measures are most effective for reducing nursing home-acquired pneumonia. Further trials are needed to draw reliable conclusions.

Abstract
OBJECTIVE Although catatonia can occur secondary to a general medical condition, catatonia itself has been known to lead to various medical compolications. Although case reports on the association of catatonia with subsequent medical complications have been documented, no comprehensive large-scale study has been performed. To investigate specific medical complications after catatonia, we conducted a retrospective cohort study of specific medical complications of schizophrenia patients with catatonia. METHODS The 1719 schizophrenia inpatients in our study were categorized into two groups: the catatonia group, i.e., those who exhibited catatonic stupor while they were hospitalized, and the noncatatonia group, i.e., those who never exhibited catatonic stupor. Differences between the two groups in the occurrence of subsequent medical complications were examined using linear and logistic regression analyses, and models were adjusted for potentially confounding factors. RESULTS The catatonia group had an increased risk for mortality (odds ratio = 4.8, 95% confidence interval = 2.0-10.6, p < .01) and certain specific medical complications, i.e., pneumonia, urinary tract infection, sepsis, disseminated intravascular coagulation, rhabdomyolysis, dehydration, deep venous thrombosis, pulmonary embolism, urinary retention, decubitus, arrhythmia, renal failure, neuroleptic malignant syndrome, hypernatremia, and liver dysfunction (all p values < .01, except for deep venous thrombosis, p = .04 in the multiple linear regression analysis). CONCLUSIONS Catatonic stupor in schizophrenia substantially raises the risk for specific medical complications and mortality. Hyperactivity of the sympathetic nervous system, dehydration, and immobility, which are frequently involved in catatonia, might contribute to these specific medical complications. In catatonia, meticulous care for both mental and medical conditions should be taken to reduce the risk of adverse medical consequences.

Abstract
Pneumonia is one of the most common infectious diseases with a high mortality, especially in the elderly population. To date, there have been only a few population-based studies dealing with the incidence of pneumonia in nursing homes (NHs). We conducted a cohort study using data from a large German statutory health insurance fund. Between 2010 and 2014, 127 227 NH residents 65 years and older were analysed. For the calculation of incidences per 100 person-years (PY) and 95% confidence intervals (CIs), we assessed the first diagnosis of pneumonia during the time in NH. We compared the rates between sexes, age groups, care levels, and comorbidities and we performed a multivariate Cox regression analysis. The mean age in the cohort was 84.0 years (74.6% female). A total of 19 183 incident cases led to an overall 5-year-incidence of 11.8 per 100 PY (95% CI 11.7-12.0). The incidence in men was substantially higher than in women. Rates were highest in the first month after NH placement. Our study revealed that the incidence of pneumonia is high in German NH residents and especially in males. Due to demographic changes, pneumonia will likely be increasingly relevant in the health care of the elderly and institutionalised population.

Abstract
RATIONALE Comorbidities, age, severity of illness, and high risk pathogens are well-known outcome determinants in community-acquired pneumonia (CAP). How these factors interact has not yet been clarified. OBJECTIVES We conducted this study to analyze the complex interaction of comorbidities, age, illness severity, and pathogens in relation to CAP. METHODS We performed a secondary analysis of the Community-Acquired Pneumonia Organization database to evaluate the impact of age in different age groups (<65, 65-79, and ≥80 yr), comorbidities (malignant disease, chronic obstructive pulmonary disease, renal and liver disease, cerebrovascular accident, congestive heart failure, and diabetes mellitus), severity of illness at admission, and etiology on the mortality of patients admitted to the hospital with CAP. MEASUREMENTS AND MAIN RESULTS A total of 6,205 patients met the inclusion criteria, and 508 (8.2%) died within 30 days. Factors independently associated with mortality were malignant disease, congestive heart failure, cerebrovascular accident, renal disease, diabetes mellitus, altered mental status, hypoxemia, pleural effusion, hematocrit less than 30%, requirement for mechanical ventilation, and being age 80 years and older. A total of 1,699 pathogens were defined in 1,545 cases; the etiology was the same for all age groups. In the overall population, mortality increased with age, but etiology was not associated with mortality. When we analyzed the patients with one comorbidity or less, we found that mortality was not different between patients younger than 65 old and those 65-79 years old, but it was higher for those aged 80 years and older. CONCLUSIONS The presence of comorbidities is associated with poorer outcomes in CAP. However, when one comorbidity or less was present, we found that being age 80 years or older was a factor that increased mortality. From a clinical standpoint, this study suggests that being age 80 years or older, instead of age 65 years and older, should be considered a risk factor for poor outcome in CAP.

Abstract
The incidence of pneumonia increases with age, and is particularly high in patients who reside in long-term care facilities (LTCFs). Mortality rates for pneumonia in older adults are high and have not decreased in the last decade. Atypical symptoms and exacerbation of underlying illnesses should trigger clinical suspicion of pneumonia. Risk factors for multidrug-resistant organisms are more common in older adults, particularly among LTCF residents, and should be considered when making empiric treatment decisions. Monitoring of clinical stability and underlying comorbid conditions, potential drug-drug interactions, and drug-related adverse events are important factors in managing elderly patients with pneumonia.

Abstract
INTRODUCTION Pneumonia is an important cause of death in care home residents. Dysphagia and poor oral health are significant risk factors for developing aspiration pneumonia. Oral hygiene care reduces the number of oral bacteria and the risk of aspiration pneumonia. However, it is not clear yet which oral hygiene care intervention is most efficacious in reducing the risk of aspiration pneumonia. The aim of the study is to assess whether the application of a 0.05% chlorhexidine-containing solution in addition to the usual daily oral hygiene care reduces the incidence of pneumonia in physically disabled care home residents with dysphagia. METHODS AND ANALYSIS The study was designed as a multicentre cluster randomised controlled clinical trial, with care homes as units of randomisation. During 1 year, 500 physically disabled care home residents with dysphagia will be followed. The intervention consists of applying a 0.05% chlorhexidine-containing solution twice daily, immediately after the usual oral hygiene care, whereas the control group receives no application after the usual oral hygiene care. The primary outcome is the incidence of pneumonia diagnosed by a physician, using a set of strictly described criteria. The effect of the intervention on the incidence of pneumonia will be determined using a Cox regression analysis. The secondary outcomes are correlations between incidence of pneumonia, age, gender, diagnosed diseases, dysphagia severity, care dependency, actually used medication, number of teeth and implants present and the presence of removable dentures. ETHICS AND DISSEMINATION Ethical approval was obtained from the Medical Ethical Committee of Radboud university medical centre: NL.nr: 41990.091.12. Written and informed consent will be obtained from all participating care homes and residents. The study's findings will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER The trial has been registered in the Netherlands in the National Trial Register: TC=3515.

Abstract
Background. Current risk stratification tools, primarily used for CAP, are suboptimal in predicting nursing home acquired pneumonia (NHAP) outcome and mortality. We conducted a systematic review to evaluate current evidence on the usefulness of proposed predictors of NHAP mortality. Methods. PubMed (MEDLINE), EMBASE, and CINAHL databases were searched for articles published in English between January 1978 and January 2014. The literature search elicited a total of 666 references; 580 were excluded and 20 articles met the inclusion criteria for the final analysis. Results. More studies supported the Pneumonia Severity Index (PSI) as a superior predictor of NHAP severity. Fewer studies suggested CURB-65 and SOAR (especially for the need of ICU care) as useful predictors for NHAP mortality. There is weak evidence for biomarkers like C-reactive protein and copeptin as prognostic tools. Conclusion. The evidence supports the use of PSI as the best available indicator while CURB-65 may be an alternative prognostic indicator for NHAP mortality. Overall, due to the paucity of information, biomarkers may not be as effective in this role. Larger prospective studies are needed to establish the most effective predictor(s) or combination scheme to help clinicians in decision-making related to NHAP mortality.

Abstract
Background: Nursing home-acquired pneumonia (NHAP) is the leading cause of death among long-term care residents. Aims: To compare current scoring indices (NHAP model score, Pneumonia Severity Index (PSI), CURB-65 (confusion, urea nitrogen, respiratory rate, blood pressure, age >65 years) and SOAR (systolic blood pressure, oxygenation, age, respiratory rate)) in predicting mortality and admission to the intensive care unit (ICU) in patients with NHAP. Methods: This retrospective observational study was conducted between July 2008 and June 2011 using data from the Korean Nursing Home Networks. Two hundred and eight nursing home residents were hospitalised with pneumonia in one general hospital. The primary outcome measure was 30-day all-cause mortality. Secondary outcome measures were intensive respiratory or vasopressor support (IRVS), and severe pneumonia (ICU admission or IRVS). Results: PSI class V showed the highest Youden index (0.45), specificity (66.7%), positive predictive value (PPV, 40.0%), negative predictive value (NPV, 91.5%), and area under the curve (AUC, 0.73) for 30-day mortality. For severe pneumonia, PSI class V showed the highest Youden index (0.40), specificity (72.8%), PPV (62.2%), NPV (77.1%), and AUC (0.70). Similarly, PSI class V showed the highest Youden index (0.35), specificity (68.3%), PPV (51.1%), NPV (80.5%), and AUC (0.69) for IRVS. Conclusions: The PSI has superior discriminatory power in predicting all three clinical outcomes (30-day mortality, severe pneumonia, and IVRS) compared with the NHAP model score, CURB-65 and SOAR.

Abstract
PURPOSE To examine accreditation from nursing homes accredited by the Commission on Accreditation of Rehabilitation Facilities (CARF) and whether this is associated with improved rehabilitation care. DESIGN Cross-sectional association of CARF accreditation and quality. METHODS Comparison of the short-stay quality measures (influenza and pneumococcal vaccination; pain; delirium; pressures sores; five-star quality and health inspection scores) between the sample of 246 CARF-accredited homes compared with the 15,393 nursing homes in the 2010 On-Line Survey Certification of Automated Records (OSCAR). FINDINGS CARF-accredited nursing homes demonstrate better quality with regard to the short-stay quality measures. CONCLUSIONS Approaches beyond traditional regulation and governmental inspections are necessary to improve the quality of care in nursing homes. CLINICAL RELEVANCE During a patient's rehabilitation stay, minimizing iatrogenic complications is paramount. Given the findings of this study, it is unfortunate that very few nursing homes are CARF accredited.

Abstract
This open-label, randomized, crossover study was conducted to demonstrate bioequivalence for telithromycin administered as crushed or whole tablets. Single 800-mg telithromycin doses (2x400-mg tablets) were administered as crushed tablets mixed in 240 mL nutritional supplement drink followed by 120 mL water or as whole tablets swallowed with 240 mL water. Plasma telithromycin concentrations were measured by liquid chromatography/mass spectrometry; pharmacokinetic parameters were determined using noncompartmental methods. Average bioequivalence criteria were applied. Thirty-two subjects received telithromycin by both methods. The 90% confidence intervals for the geometric mean ratios of maximum plasma concentration and area under the plasma concentration-time curve to 24 hours were within the 0.80 to 1.25 range. Median tmax was 3.00 hours for both treatments. Both methods of administration were well tolerated. Crushing telithromycin tablets and administering them with a nutritional supplement drink is bioequivalent to ingesting whole tablets and could be a viable method of administration for patients unable to swallow tablets whole.

Abstract
BACKGROUND This study compares biomarker (including procalcitonin, pro-ANP, and copeptin) levels to pneumonia severity scores to predict 30-day mortality in NHAP (nursing home acquired pneumonia) patients. METHODS Seventy three patients aged ≥ 65 y, admitted to general hospitals and who fulfilled the definition of NHAP were included in the study. Data collected at admission included age, gender, nursing home admission, coexisting illness, symptoms and clinical parameters (blood pressure, pulse rate, respiratory rate and status). Additional data collected included laboratory results, radiographic findings and outcome variables. Severity of pneumonia was evaluated using a prediction rule calculated by CURB-65 criteria (confusion, urea nitrogen, respiratory rate, blood pressure, age>65 y). RESULTS After adjustment for age, sex and CURB-65, copeptin (OR=5.60, 95% confidence interval (CI)=1.20-26.24) was associated with 30-day mortality in NHAP patients, while procalcitonin and pro-ANP were not. The areas under the receiver operating characteristic curves (AUCs) for CURB-65, in predicting mortality were 0.685 [95% CI 0.559-0.811], whereas copeptin showed slightly superior accuracy with an AUC of 0.698 (95% CI 0.568-0.827). CONCLUSIONS Among 3 biomakers, copeptin was the strongest predictor of 30-day mortality from NHAP. The pathophysiologic and clinical implications of this finding require further investigation.

Abstract
Red fluorescent proteins can generate reactive oxygen species (ROS) if their fluorochrome is stimulated e.g. by visible light illumination. ROS compounds have very reactive, highly toxic properties leading to cell damage which results in cell killing. In this context, the toxicity of the various red fluorochromes KillerRed, DsRed2, mCherry, and mRFP expressed in Escherichia coli bacteria was tested after illumination with white light. The toxic effect was determined by measurement of the colony forming ability 24h after transfection and illumination. KillerRed was found to be the most harmful, followed by mRFP and DsRed2 while bacteria expressing mCherry and controls without fluorescent proteins survived after application of identical illumination doses. Their application and a possible bactericide role is discussed.

Abstract
In accordance with the international and national guidelines, the Emilia-Romagna Region (Italy) has established regional guidelines for the surveillance and prevention of legionellosis based on the concept of risk assessment, with particular attention to environmental monitoring. The aim of this study was to verify how environmental surveillance in the context of risk assessment plans could help to guide decisions about preventive strategies against Legionella infections in Long Term Care Facilities (LTCF). In six LTCFs in the city of Bologna (Emilia-Romagna Region) a self-control plan was implemented that included the environmental monitoring of Legionella spp. and the surveillance of hospital-acquired Legionnaires' Disease. At baseline, four hot water systems were colonized by Legionella pneumophila (3 LCTFs) and Legionella londiniensis (1 LCTF). In each establishment specific control measures were adopted based on the characteristics of the system, the virulence of the strain and the level of the contamination. The monitoring, carried out for around two years, was also extended to the ways in which the system and the distal water distribution points were used and maintained with respect to the good practices in operation and management. The adopted actions (shock and/or continuous disinfection treatments) and the implementation of the good practice measures reduced the contamination to acceptable and stable levels. No cases of hospital-acquired legionellosis occurred during the period of study. The environmental surveillance was successful in evaluating the risk and identifying the most suitable preventive strategies.

Abstract
BACKGROUND Donepezil is a potent inhibitor of acetylcholinesterase, an enzyme that is targeted in the treatment of Alzheimer's disease. OBJECTIVE The purpose of this study was to compare the pharmacokinetic characteristics of orally disintegrating (test) and conventional (reference) donepezil formulations to satisfy the regulatory requirement for marketing. METHODS A single-center randomized, single-dose, open-label, 2-way crossover study with a 21-day washout period was conducted in 22 healthy volunteers. Plasma samples for the analysis of donepezil were collected up to 240 hours after drug administration. Participants received either reference or test drug formulation of 10 mg donepezil in the first period and the alternative formulation in the second period. Plasma concentrations of donepezil were determined by validated high-performance liquid chromatography coupled to tandem mass spectrometry detection. Pharmacokinetic parameters, including C(max) and AUC, were determined by noncompartmental analysis. ANOVA was carried out using log-transformed C(max) and AUC, and the mean ratios and their 90% CIs were calculated. The safety profiles and tolerabilities of the 2 formulations were also assessed based on laboratory tests, 12-lead ECGs, vital signs, and physical examinations. RESULTS Of the 22 participants initially enrolled, 18 healthy Korean participants completed both treatment periods. Four subjects did not complete both treatments: 3 subjects withdrew consent for personal reasons, and 1 subject experienced adverse events. No significant differences in pharmacokinetic parameters between the 2 formulations were observed. The mean (SD) age, height, and weight of the participants were 25.8 (4.1) years, 173.6 (5.7) cm, and 68.9 (7.8) kg, respectively. The mean (SD) C(max), AUC(last), and AUC(inf) for the reference formulation were 33.26 (6.58) ng/mL, 1521.69 (344.04) ng × h/mL, and 1691.46 (443.05) ng × h/mL, respectively. Corresponding values for the test formulation were 34.23 (6.79) ng/mL, 1554.33 (390.23) ng × h/mL, and 1718.27 (447.03) ng × h/mL, respectively. The median T(max) was 2 hours (range, 1-3 hours) for the reference and test formulations. The geometric mean ratios (90% CI) between the 2 formulations of donepezil were 102.9 (96.8-109.5) for C(max), 102.3 (96.1-108.9) for AUC(last), and 101.6 (95.4-108.2) for AUC(0-∞), respectively. During the study, 15 and 14 adverse events were reported for the reference and test formulations, respectively, and all were transient, mild, and resolved during the treatment period. These adverse events included 7 cases of nausea, 3 cases of headache, and 1 case each of dizziness, vomiting, chills, and sweating. All adverse events were considered related to the study drugs. CONCLUSION This study found that the test and reference formulations met the regulatory criteria for pharmacokinetic equivalence in these fasting healthy Korean male subjects. Both donepezil formulations appeared to be generally well tolerated.

Abstract
OBJECTIVE To review the risk factors, etiologic profile, treatment approaches, and guidelines for the management of nursing home-acquired pneumonia (NHAP). RESEARCH DESIGN AND METHODS A search of the current literature was conducted using the MEDLINE and Embase databases. This search, limited to studies performed in humans and published in English between January 1, 1990 and October 31, 2009, included the terms 'acquired pneumonia', 'associated pneumonia', 'nursing home', 'long-term care', 'institution', and 'healthcare'. RESULTS Older age, male gender, swallowing difficulty, and inability to take oral medications are all significant risk factors for pneumonia. Medications such as antipsychotics and anticholinergics, histamine receptor blockers and proton pump inhibitors have also been linked to higher risk of pneumonia. The etiology of NHAP overlaps with that of community-acquired pneumonia (CAP), with Streptococcus pneumoniae and Haemophilus influenzae as predominant pathogens in long-term care facilities. In patients who require hospitalization, Chlamydophila pneumoniae, Staphylococcus aureus, and influenza virus have also been identified. In contrast, the etiology of severe NHAP overlaps with that of hospital-acquired pneumonia (HAP), with S. aureus, including methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, and enteric Gram-negative bacilli as important causative pathogens. Therapy is dependent on disease severity and, on the treatment setting. Respiratory fluoroquinolones or β-lactams plus a macrolide are recommended in patients with NHAP. Patients hospitalized with severe NHAP may require triple combination therapy that covers both MRSA and P. aeruginosa. However, there is little evidence of the clinical superiority of one regimen over another, making it challenging to establish guidelines for the treatment of NHAP in the nursing home setting. CONCLUSION There is a pressing need for clinical trials of antibiotic therapy in nursing home patients that would help establish uniform guidelines to standardize therapy in the nursing home setting.

Abstract
Healthcare-associated pneumonia (HCAP) is a newly identified condition, and epidemiologic studies in Japan are still limited. We retrospectively observed patients with HCAP and community-acquired pneumonia (CAP) who were hospitalized between December 2004 and March 2005, and compared their disease characteristics. A total of 34 patients (14 with HCAP and 20 with CAP) were evaluated. Of the patients with HCAP, seven (50%) were hospitalized for at least 2 days in the preceding 90 days and five (35.7%) resided in a nursing home or extended care facility. Compared with patients with CAP, patients with HCAP were older, had more complications, including central nerve diseases, had greater disease severity, but lower serum albumin level. More methicillin-resistant Staphylococcus aureus, Pseudomonas spp., and anaerobes were isolated from patients with HCAP than from those with CAP. Conversely, more Streptococcus pneumoniae was detected and more penicillin was used in patients with CAP. This study provides additional evidence that HCAP should be distinguished from CAP and suggests the pathogenesis and therapeutic strategy for HCAP may be similar to those for hospital-acquired pneumonia.

Abstract
OBJECTIVES We examined racial disparities in receipt and documentation of influenza and pneumococcus vaccinations among nursing-home residents. METHODS We performed secondary analyses of data from a nationally representative survey of White (n = 11 448) and Black (n = 1174) nursing-home residents in 2004. Bivariate and multivariate analyses determined racial disparities in receipt of influenza vaccination in 2003 and 2004, receipt of pneumococcus vaccination ever, and having a documented history for each vaccination. RESULTS The overall vaccination rate was 76.2% for influenza and 48.5% for pneumococcus infection. Compared with Whites, Blacks showed a 13% lower vaccination rate and a 5% higher undocumentation rate for influenza, and a 15% lower vaccination rate and a 7% higher undocumentation rate for pneumococcus. For influenza, the odds ratio (OR) for Blacks being unvaccinated was 1.84 (P < or = .001), and the OR for Blacks having undocumented vaccination was 1.85 (P = .001). For pneumococcus infection, the OR for Blacks being unvaccinated was 1.70 (P < or = .001), and the OR for Blacks having undocumented vaccination was 1.95 (P < or = .001). Stratified analyses confirmed persistent racial disparities among subpopulations. CONCLUSIONS Racial disparities exist in vaccination coverage among US nursing-home residents. Targeted interventions to improve vaccination coverage for minority nursing-home residents are warranted.

Abstract
BACKGROUND Considerable research has increased our understanding of antibiotic prescribing practices in hospital settings when it comes to nosocomial pneumonia. Much less is known about the antibiotic prescribing patterns for hospitalized non-critically ill patients with nursing home-acquired pneumonia (NHAP). OBJECTIVE As part of a multisite quality improvement project, we sought to examine patterns of antibiotic prescription among healthcare providers as a function of underlying comorbid, functional, and clinical factors. SETTING Three tertiary care centers. INTERVENTION Chart reviews of 397 individual admissions were performed on patients admitted from nursing homes with the diagnosis of pneumonia between January 2005 and September 2007. RESULTS Compliance with national guidelines for the treatment of NHAP was poor. Overall, the 3 most commonly used compounds for inpatient treatment were fluoroquinolones (51.4%), ceftriaxone (45.0%), and azithromycin (42.1%). Monotherapy was prescribed in 57.1%. Fluoroquinolones represented 79.5% of these cases. Patients with higher acuity of illness were more likely to receive a combination of vancomycin plus piperacillin/tazobactam (P < 0.001). Median duration of treatment was 8.0 (range, 3-21) days. Stratified analyses showed that combination therapy was used more often on University-affiliated services than on private service (54% vs. 35%; P < 0.001). CONCLUSIONS There was poor adherence with antibiotic guidelines for the treatment of NHAP. In the absence of outcome data on guidelines compliance, antibiotic use was influenced by patients' age, severity of illness, and providers' academic affiliation. Future research should focus on outcome measures and physicians factors that influence nonadherence.

Abstract
Older patients disproportionately suffer the burden of infection in the community and in health care facilities. The rational approach to antimicrobial therapy for older patients with infection requires an appreciation and understanding of the complex immunologic, epidemiologic, pharmacologic, and microbiologic factors that influence the manifestations and consequences of infection in this group. Specific recommendations for common infectious syndromes must take into account the unique needs of older patients and should be tailored for each individual case.

Abstract
Low zinc status may be a risk factor for pneumonia in the elderly. This special article reviews the magnitude of the problem of pneumonia (its prevalence, morbidity, and mortality) in the elderly, pneumonia's etiology, and the dysregulation of the immune system associated with increasing age. In addition, recent evidence from the literature is presented demonstrating that low zinc status (commonly reported in the elderly) impairs immune function, decreases resistance to pathogens, and is associated with increased incidence and duration of pneumonia, increased use and duration of antimicrobial treatment, and increased overall mortality in the elderly. Inadequate stores of zinc might, therefore, be a risk factor for pneumonia in the elderly. Randomized, double-blind, controlled studies are needed to determine the efficacy of zinc supplementation as a potential low-cost intervention to reduce morbidity and mortality due to pneumonia in this vulnerable population.

Abstract
The rate of healthcare-associated infections can be regarded as an important outcome parameter of the hygienic quality of care in nursing homes. Our study aimed to evaluate the applicability of repeated prevalence investigations as a tool for surveillance of healthcare-associated infections in nursing homes. From December 2006 to September 2007 a total of five prevalence investigations were conducted in four nursing homes each (n=2,369 residents). Initially, defined structural and procedural parameters of the hygienic quality of the four nursing homes were evaluated based on a detailed inspection and a checklist including 40 parameters. The results showed a uniformly high level of the hygienic quality with only minor variation (mean 84%, range 75%-93% of parameters fulfilled). In total, the prevalence of healthcare-associated infections was 6.8%, with a marked increase with higher categories of dependency (3.5%, 4.0%, 8.5%, and 12.3%, respectively, in the categories 0, I, II, and III of the German grading of skilled nursing care). Respiratory tract (4.1%), skin/soft tissue (1.5%), and urinary tract infections were the most prevalent healthcare-associated infections. Respiratory tract infections showed a marked seasonal pattern. During the second prevalence investigation (February 2007), an outbreak of upper respiratory tract infections occurred in one of the nursing homes (attack rate, 17%). The crude prevalence rates showed considerable differences between the four nursing homes; however, after adjusting for the different categories of dependency, the standardized infection rates (SIR) were largely comparable (excluding the outbreak). After inclusion of the outbreak, the SIR of the specific nursing home was significantly higher compared to all other nursing homes. In conclusion, our study shows that repeated prevalence investigations can be an easy to use tool for surveillance of healthcare-associated infections as a surrogate parameter of the hygienic quality in nursing homes. This implies a knowledge of the seasonality of specific infections and a risk adjustment according to the categories of dependency. The primary intention of surveillance should be the identification of hygienic problems. However, the resources should preferentially be focused on hygienic structures and processes.

Abstract
In the long-term care setting The diagnosis of infection is primarily based from the clinical assessment. Infection is a common cause of fever, when present, and acute change in functional status. Infection can often present atypically; usual symptoms, physical findings, and diagnostic abnormalities may be lacking. Evaluation of fever and suspected infection should initially focus on the most common clinical syndromes. Treatment should initially focus on the most common organisms that are present at the most likely suspect site of infection.

Abstract
Pneumonia is a common and important disease in the elderly. The incidence is expected to rise as the population ages, and, therefore, it will become an increasingly significant problem in hospitals and the community. A comprehensive literature review was performed in order to look at the characteristics of pneumonia in the elderly population. In particular, the epidemiology, etiology and pathogenesis--including risk factors, microbiology, and clinical features--were evaluated. While aging causes physiological changes which make elderly patients more susceptible to pneumonia, it was found that comorbidities, rather than age, are also an important risk factor. The most common micro-organism responsible for pneumonia is Streptococcus pneumoniae, but other organisms need to be considered, depending on the environment of presentation. Elderly patients are more likely than younger adults to present with an absence of fever and an altered mental state. Nursing home residents tend to present with more atypical and less characteristic symptoms.

Abstract
Healthcare-associated pneumonia (HCAP) is a relatively new entity that includes pneumonia occurring in healthcare settings other than acute-care hospitals. Many patients with HCAP are at greater risk for colonization and infection with multi-drug resistant (MDR) bacteria such as Pseudomonas aeruginosa, Gram-negative bacilli-producing extended-spectrum beta-lactamases and methicillin-resistant Staphylococcus aureus. Infections with these MDR pathogens require different empiric antibiotic therapy. To avoid initiation of inappropriate antibiotic therapy that may result in poorer patient outcomes, new principles for HCAP management were outlined in the 2005 American Thoracic Society and Infectious Diseases Society of America guidelines. These guidelines were suggested for patients assessed in acute-care hospitals and clinics, and may not be applicable for all patients with suspected HCAP in nursing homes and other long-term care settings. This review article addresses HCAP management strategies in both clinical settings.

Abstract
BACKGROUND Hardly any data on the occurrence of infection in Italian nursing homes have been published; yet Italy has the second oldest population in the world. The objective of the study was to assess the frequency of infections in a sample of Italian nursing homes. MATERIALS AND METHODS A 1-day prevalence survey was conducted in three local health authorities (LHAs) of the Emilia-Romagna region in Italy, aimed at describing the prevalence of patients with long-term care facilityassociated infections and their associated factors among residents of nursing and residential facilities. All nursing homes (NHs) and a stratified random sample of residential homes (RHs) in the three LHAs were included in the study, for a total of 1,926 elderly people in 49 facilities. The following data were recorded: infections, medical condition, activities of daily living (ADL), use of antibiotics. The main outcome of the study was infection prevalence. RESULTS The prevalence of patients with long-term care facility-associated infection was 8.4/100 residents overall (CI 95% 7.9-9.0), 14.6/100 in NHs and 7.5/100 in RHs (CI 95% 6.8-8.1). The prevalence of infection significantly varied with LHA and facility. It was associated with level of dependency and exposure to invasive procedures, such as urinary catheterization and parenteral procedures. Six percent of residents received a systemic antimicrobial on the day of the study, and in 22% of cases there was no evidence of suspected or diagnosed infections. CONCLUSION The prevalence study identified a high prevalence of infected patients in nursing homes in Italy, consistent with observation in other geographic areas.
