Abstract
BACKGROUND Hand hygiene (HH) among health care workers (HCWs) is crucial in preventing infections in nursing homes. However, HH compliance (HHC) among HCWs remains low. This study aimed to investigate the effect of feedback lights on HCWs' HHC. METHODS A 5-month interventional study was conducted in 3 wards in a nursing home in Denmark. During the intervention period, a green light with a smiley appeared on the alcohol-based hand rub (ABHR) dispensers when HCWs used the ABHR, acknowledging HCWs for using the ABHR. HHC was monitored using an automatic HH monitoring system (AHHMS). RESULTS A total of 64 HCWs were enrolled. The AHHMS collected 23,696 HH opportunities in apartments and dirty utility rooms. Overall, HHC in the apartments increased from 50% at baseline (95% CI: 48, 53) to 56% (95% CI: 54, 58) during the intervention. However, the increased HHC level was not sustained during follow-up. CONCLUSIONS The AHHMS enabled the assessment of the intervention. We found a significant effect of light-guided feedback in the apartments. However, the increased HHC was not sustained after the light was switched off.

J Am Geriatr Soc 2024; 72:1468-1475. [PMID: 38241465 PMCID: PMC11090732 DOI: 10.1111/jgs.18778] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 12/19/2023] [Accepted: 12/23/2023] [Indexed: 01/21/2024]
Abstract
BACKGROUND Evaluating infection in home-based primary care is challenging, and these challenges may impact antibiotic prescribing. A refined understanding of antibiotic decision-making in this setting can inform strategies to promote antibiotic stewardship. This study investigated antibiotic decision-making by exploring the perspectives of clinicians in home-based primary care. METHODS Clinicians from the Department of Veterans Affairs Home-Based Primary Care Program were recruited. Semi-structured interviews were conducted from June 2022 through September 2022 using a discussion guide. Transcripts were analyzed using grounded theory. The constant comparative method was used to develop a coding structure and to identify themes. RESULTS Theoretical saturation was reached after 22 clinicians (physicians, n = 7; physician assistants, n = 2, advanced practice registered nurses, n = 13) from 19 programs were interviewed. Mean age was 48.5 ± 9.3 years, 91% were female, and 59% had ≥6 years of experience in home-based primary care. Participants reported uncertainty about the diagnosis of infection due to the characteristics of homebound patients (atypical presentations of disease, presence of multiple chronic conditions, presence of cognitive impairment) and the challenges of delivering medical care in the home (limited access to diagnostic testing, suboptimal quality of microbiological specimens, barriers to establishing remote access to the electronic health record). When faced with diagnostic uncertainty about infection, participants described many factors that influenced the decision to prescribe antibiotics, including those that promoted prescribing (desire to avoid hospitalization, pressure from caregivers, unreliable plans for follow-up) and those that inhibited prescribing (perceptions of antibiotic-associated harms, willingness to trial non-pharmacological interventions first, presence of caregivers who were trusted by clinicians to monitor symptoms). CONCLUSIONS Clinicians face the difficult task of balancing diagnostic uncertainty with many competing considerations during the treatment of infection in home-based primary care. Recognizing these issues provides insight into strategies to promote antibiotic stewardship in home care settings.

Abstract
BACKGROUND Elderly nursing home residents are vulnerable to infection from micro-organisms. Hand hygiene is considered one of the most important measures to prevent transmission. AIM To determine the effect of increased accessibility to alcohol-based hand rub (ABHR) in nursing home wards by monitoring hand hygiene compliance (HHC) among healthcare workers (HCWs). METHODS An 11-month intervention study was conducted in a Danish six-ward nursing home. Data were collected using an automatic hand hygiene monitoring system (AHHMS). After a baseline period, one extra ABHR dispenser was placed in each of the 150 apartments. Baseline HHC was compared with the HHC during an immediate intervention period and a long-term intervention period. FINDINGS A total of 159 HCWs were included. The AHHMS registered 341,078 hand hygiene opportunities. Overall baseline HHC was 31% (95% confidence interval: 30-32). A significant +18% absolute immediate effect (first five months) (95% CI: 17-19; P < 0.0001) and +13 percentage points (95% CI: 11-14; P < 0.0001) long-term effect (another four months) were recorded. HCWs working day shifts and short-term employees had a higher baseline HHC than HCWs working evening/night shifts. However, HCWs working night shifts achieved the greatest long-term effect with a mean +27 percentage point difference (P < 0.0001). CONCLUSION Placing an additional ABHR dispenser strategically within staff workflow significantly increased HHC among HCWs, demonstrating a noteworthy effect. The study is the first to report the effect on nursing home dispenser accessibility as a single intervention and to show a significant unmet potential.

Abstract
Immune system aging is becoming a field of increasing public health interest because of prolonged life expectancy, which is not paralleled by an increase in health expectancy. As age progresses, innate and adaptive immune systems undergo changes, which are defined, respectively, as inflammaging and immune senescence. A wealth of available data demonstrates that these two conditions are closely linked, leading to a greater vulnerability of elderly subjects to viral, bacterial, and opportunistic infections as well as lower post-vaccination protection. To face this novel scenario, an in-depth assessment of the immune players involved in this changing epidemiology is demanded regarding the individual and concerted involvement of immune cells and mediators within endogenous and exogenous factors and co-morbidities. This review provides an overall updated description of the changes affecting the aging immune system, which may be of help in understanding the underlying mechanisms associated with the main age-associated infectious diseases.

J Am Geriatr Soc 2024; 72:1060-1069. [PMID: 38348519 DOI: 10.1111/jgs.18786] [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: 09/22/2023] [Revised: 01/07/2024] [Accepted: 01/10/2024] [Indexed: 04/16/2024]
Abstract
BACKGROUND Antibiotics play a central role in infection management. In older patients, antibiotics are frequently administered subcutaneously. Ceftriaxone pharmacokinetics after subcutaneous administration is well documented, but little data are available on its safety. METHODS We compared the occurrence of adverse events associated with ceftriaxone administered subcutaneously versus intravenously in ≥75-year-old patients. We used data from a single-center, retrospective, clinical-administrative database to compare the occurrence of adverse events at day 14 and outcome at day 21 in older patients who received ceftriaxone via the subcutaneous route or the intravenous route at Rennes University Hospital, France, from May 2020 to February 2023. RESULTS The subcutaneous and intravenous groups included 402 and 3387 patients, respectively. Patients in the subcutaneous group were older and more likely to receive palliative care. At least one adverse event was reported for 18% and 40% of patients in the subcutaneous and intravenous group, respectively (RR = 2.21). Mortality at day 21 was higher in the subcutaneous route group, which could be linked to between-group differences in clinical and demographic features. CONCLUSIONS In ≥75-year-old patients, ceftriaxone administered by the subcutaneous route is associated with less-adverse events than by the intravenous route. The subcutaneous route, which is easier to use, has a place in infection management in geriatric settings.

Abstract
Knowledge of aging biology needs to be expanded due to the continuously growing number of elderly people worldwide. Aging induces changes that affect all systems of the body. The risk of cardiovascular disease and cancer increases with age. In particular, the age-induced adaptation of the immune system causes a greater susceptibility to infections and contributes to the inability to control pathogen growth and immune-mediated tissue damage. Since the impact of aging on immune function, is still to be fully elucidated, this review addresses some of the recent understanding of age-related changes affecting key components of immunity. The emphasis is on immunosenescence and inflammaging that are impacted by common infectious diseases that are characterized by a high mortality, and includes COVID-19, HIV and tuberculosis.

Abstract
BACKGROUND Current understanding of the etiology, natural history, and outcomes of acute generalized exanthematous pustulosis (AGEP) has been limited, with most available studies consisting of small or heterogenous cohorts. OBJECTIVES The aim of this study was to further characterize associated factors and disease outcomes of AGEP. METHODS A cross-sectional study design was employed with formal inclusion and causality criteria. Patients were identified from an inpatient database at an academic medical center, including 65 patients with AGEP and a control group of 61 patients with non-severe cutaneous adverse reactions. RESULTS Increased age and body mass index (BMI) were associated with higher risk of AGEP (p < 0.001). Length of stay was longer for both the overall AGEP cohort (13.1 days) and a subcohort with a primary discharge diagnosis of AGEP (9.7 days) compared with the control group (3.6 days) [p < 0.001]. Patients with AGEP were more likely to be discharged to a long-term care facility compared with control patients (p < 0.001). CONCLUSIONS AGEP was associated with longer length of hospitalization, higher rates of discharge to long-term care facilities, and higher mortality compared with non-severe cutaneous adverse drug reaction (SCAR) medication reactions. Future research should examine the association between morbid obesity and this particular drug reaction, and the possibility of decreasing hospitalization length given the relatively low risk of mortality among patients with AGEP.

Abstract
There are limited data on the pharmacokinetics (PK) and pharmacodynamics (PD) of polymyxin B in the elderly population. The objective of this study was to develop a population PK model of polymyxin B in elderly patients, determine factors that affect its PK parameters, and propose alternative dosing regimens. Critically ill elderly patients (age ≥65 years) who received intravenous polymyxin B for multi-drug-resistant Gram-negative bacterial infections were enrolled. A population PK model was developed using Phoenix NLME software. Monte Carlo simulations were performed to optimize regimens attaining the PK/PD target of AUC24h/MIC >50 and target exposure of 50-100 mg‧h/L. Clinical efficacy and nephrotoxicity of polymyxin B treatment were also assessed. A total of 142 polymyxin B concentrations from 23 patients were available. A two-compartment model with first-order elimination was developed, and albumin was the significant covariate of PK parameters. However, albumin had only a slight effect on polymyxin B exposure. Simulation results indicated that two fixed regimens of 50 mg and 75 mg would be sufficient to reach the PK/PD targets when the minimum inhibitory concentrations was ≤0.5 mg/L. With the exception of 1.25 mg/kg for 58 kg, other weight-based regimens (1.25-1.5 mg/kg for 70 kg and 80 kg; twice daily) may result in at least 40% of predicted AUCss,24h >100 mg‧h/L. In conclusion, fixed maintenance dosing of 50 mg and 75 mg for polymyxin B may maximize efficacy while balancing nephrotoxicity concerns for elderly patients.

Abstract
Clostridioides difficile infection (CDI) represents a significant cause of morbidity and mortality, mainly in older and frail subjects. Early identification of outcome predictors, starting from emergency department (ED) admission, could help to improve their management. In a retrospective single-center study on patients accessing the ED for diarrhea and hospitalized with a diagnosis of CDI infection, the patients’ clinical history, presenting symptoms, vital signs, and laboratory exams at ED admission were recorded. Quick sequential organ failure assessments (qSOFA) were conducted and Charlson’s comorbidity indices (CCI) were calculated. The primary outcomes were represented by all-cause in-hospital death and the occurrence of major cumulative complications. Univariate and multivariate Cox regression analyses were performed to establish predictive risk factors for poor outcomes. Out of 450 patients, aged > 81 years, dyspnea at ED admission, creatinine > 2.5 mg/dL, white blood cell count > 13.31 × 109/L, and albumin < 30 µmol/L were independently associated with in-hospital death and major complications (except for low albumin). Both in-hospital death and major complications were not associated with multimorbidity. In patients with CDI, the risk of in-hospital death and major complications could be effectively predicted upon ED admission. Patients in their 8th decade have an increased risk independent of comorbidities.

Abstract
PURPOSE Data on encephalitis in elderly patients are scarce. We aimed to describe the characteristics, aetiologies, management, and outcome of encephalitis in patients older than 65 years. METHODS We performed an ancillary study of ENCEIF, a prospective cohort that enrolled all cases of encephalitis managed in 46 clinical sites in France during years 2016-2019. Cases were categorized in three age groups: (1) 18-64; (2) 65-79; (3) ≥ 80 years. RESULTS Of the 494 adults with encephalitis enrolled, 258 (52%) were ≥ 65 years, including 74 (15%) ≥ 80 years. Patients ≥ 65 years were more likely to present with coma, impaired consciousness, confusion, aphasia, and rash, but less likely to present with fever, and headache (P < 0.05 for each). Median cerebrospinal fluid (CSF) white cells count was 61/mm3[13-220] in 65-79 years, 62 [17-180] in ≥ 80 years, vs. 114 [34-302] in < 65 years (P = 0.01). The proportion of cases due to Listeria monocytogenes and VZV increased after 65 years (P < 0.001), while the proportion of tick-borne encephalitis and Mycobacterium tuberculosis decreased with age (P < 0.05 for each). In-hospital mortality was 6/234 (3%) in < 65 years, 18/183 (10%) in 65-79 years, and 13/73 (18%) in ≥ 80 years (P < 0.001). Age ≥ 80 years, coma on admission, CSF protein ≥ 0.8 g/L and viral encephalitis were independently predictive of 6 month mortality. CONCLUSION Elderly patients represent > 50% of adults with encephalitis in France, with higher proportion of L. monocytogenes and VZV encephalitis, increased risk of death, and sequels. The empirical treatment currently recommended, aciclovir and amoxicillin, is appropriate for this age group.

FRONTIERS IN MEDICAL TECHNOLOGY 2022; 4:912469. [PMID: 36340588 PMCID: PMC9632861 DOI: 10.3389/fmedt.2022.912469] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 08/25/2022] [Indexed: 11/30/2022] Open
Abstract
Background Infectious disease in aging adults (≥61 years) often occurs in combination with other health conditions leading to long hospital stays. Detailed studies on infection in aging adults investigating this problem are sparse. Aim To quantify the effect of primary and secondary diagnosed infections on hospitalization bed-days among aging adult patients. Design Retrospective patient-file study. Setting Ziekenhuis Netwerk Antwerpen (ZNA) Hospital, a 1,858-bed general hospital in Belgium, with 364 beds allocated to geriatric patients. Data source Database of hospitalized adult patients aged ≥61 years. Methods All adult patients aged ≥61 years hospitalized on two wards, Geriatrics and Pulmonology, from 2010 to 2014 were included. Primary diagnosed infections were defined as infections known at entry to be treated first. Secondary diagnosed infections included infections known at entry but treated in parallel to primary non-infectious causes of entry, infections unknown at entry, and hospital-acquired (nosocomial) infections. Data were analyzed by patient age, gender, year, ward type, bed-days of hospitalization, infection rates, and seasonality. Results There were 3,306 primary diagnosed infections (18%) and 14,758 secondary infections (82%) identified in the two wards combined (54.7% of all hospital stays at those 2 wards). Secondary diagnosed infections accounted for a significantly higher proportion of hospitalizations in both wards (+40% for Geriatric ward; +20% for Pulmonology ward; p < 0.001) and were associated with a significantly longer average hospital stay (+4 days for Geriatric ward; +5 days for Pulmonology ward; p < 0.001). Nosocomial infections (12% for Geriatric ward; 7% for Pulmonology ward) were associated with particularly high bed-days of hospitalization, at approximately +15 days and +12 days on Geriatric and Pulmonology wards, respectively. Both wards showed marked seasonality for respiratory infections with winter peaks. Conclusion Real-world data showed that secondary diagnosed infections in aging adults imposed a high burden on hospital care along with longer hospital stays. This hampered bed availability during peak seasons.

Abstract
Background Over 7 million older Americans are homebound. Managing infections in homebound persons presents unique challenges that are magnified among persons living with dementia (PLWD). This work sought to characterize antibiotic use in a national cohort of PLWD who received home-based primary care (HBPC) through the Veterans Health Administration. Methods Administrative data identified veterans aged ≥65 years with ≥2 physician home visits in a year between 2014 and 2018 and a dementia diagnosis 3 years before through 1 year after their initial HBPC visit. Antibiotics prescribed orally, intravenously, intramuscularly, or by enema within 3 days of an HBPC visit were assessed from the initial HBPC visit to death or December 31, 2018. Prescription fills and days of therapy (DOT) per 1000 days of home care (DOHC) were calculated. Results Among 39 861 PLWD, the median age (interquartile range [IQR]) was 85 (78-90) years, and 15.0% were Black. Overall, 16 956 (42.5%) PLWD received 45 122 prescription fills. The antibiotic use rate was 20.7 DOT per 1000 DOHC. Telephone visits and advanced practice provider visits were associated with 30.9% and 42.0% of fills, respectively. Sixty-seven percent of fills were associated with diagnoses for conditions where antibiotics are not indicated. Quinolones were the most prescribed class (24.3% of fills). The overall median length of therapy (IQR) was 7 (7-10) days. Antibiotic use rates varied across regions. Within regions, the median annual antibiotic use rate decreased from 2014 to 2018. Conclusions Antibiotic prescriptions were prevalent in HBPC. The scope, appropriateness, and harms of antibiotic use in homebound PLWD need further investigation.

Characteristics of Patients Who Visited Emergency Department: A Nationwide Population-Based Study in South Korea (2016-2018). INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:ijerph19148578. [PMID: 35886425 PMCID: PMC9316116 DOI: 10.3390/ijerph19148578] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Revised: 07/05/2022] [Accepted: 07/12/2022] [Indexed: 11/17/2022]
Abstract
The utilization of the emergency department (ED) has been continuously increasing and has become a burden for ED resources. The aim of this study was to describe the characteristics, outcomes, common diagnoses, and disease classifications of patients who were referred to the ED. This nationwide epidemiologic study examined the data from adult patients (>18 years) who visited EDs from 1 January 2016 to 31 December 2018. Most EDs in Korea provide data from ED patients to the National Emergency Medical Center (NEMC). The disposition of ED patients was classified as discharge, admission, death, and re-transfer. From 2016 to 2018, the proportion of referred patients out of the total ED visits increased from 7.3% to 7.8%. The referred patients were older (61.1 vs. 50.5 years), had worse vital signs, longer ED lengths of stay (409.1 vs. 153.3 min), and higher admission (62.3 vs. 16.9%) and re-transfer rates (4.4 vs. 1.9%) than the direct-visit patients. Among the referred patients in the 3 years, 62.3% were hospitalized, and the most common disease classification was “disease of the digestive system” (19.8%). The most common diagnosis was pneumonia (6.0%), followed by urinary tract infection, gastrointestinal bleeding, and hepatobiliary infection. The number of patients referred to EDs is increasing, and more than 60% of referred patients are hospitalized. Detailed characteristics of these patients will be helpful for improving ED management and the distribution of medical resources.

Abstract
OBJECTIVES To reduce infections with Clostridioides difficile (CDI) in geriatric patients by interventions easily implementable in standard clinical care. METHODS Prevalence and incidence of CDI between January 2015 and February 2020 were analysed (n = 25,311 patients). Pre-intervention status was assessed from April 2016 to March 2017 (n = 4,922). Between May 2017 and August 2019, a monocentric interventional crossover study (n = 4,655) was conducted including standard care and three interventions: (A) sporicidal cleaning of hospital wards, (B) probiotics and (C) improvement in personal hygiene for CDI patients. This was followed by a multicentric comparison of the interventional bundle (A + B + C) between September 2019 and February 2020 (n = 2,593) with the pre-intervention phase. In 98 CDI cases and matched controls individual risk factors for the development of CDI were compared. RESULTS Time series analyses of CDI cases revealed a reduction in the prevalence of CDI in all three participating centres prior to the multicentric intervention phase. In the monocentric phase, no effect of individual interventions on CDI prevalence was identified. However, an aggregated analysis of CDI cases comparing the pre-intervention and the multicentric phase revealed a significant reduction in CDI prevalence. Risk factors for the development of CDI included use of antibiotics, anticoagulants, previous stay in long-term care facilities, prior hospital admissions, cardiac and renal failure, malnutrition and anaemia. CONCLUSIONS The observed reduction in CDI may be attributed to heightened awareness of the study objectives and specific staff training. Individual interventions did not appear to reduce CDI prevalence. A further randomised trial would be necessary to confirm whether the bundle of interventions is truly effective.

Prolonged carriage of ESBL-producing enterobacterales and potential cross-transmission among residents in geriatric long-term care facilities. Sci Rep 2021; 11:21607. [PMID: 34732819 PMCID: PMC8566574 DOI: 10.1038/s41598-021-01190-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2021] [Accepted: 10/25/2021] [Indexed: 11/09/2022] Open
Abstract
Previous studies indicated residents in geriatric long-term care facilities (LTCFs) had much higher prevalence of extended-spectrum β-lactamase-producing Enterobacteriaceae (ESBL-E) carriage than the general population. Most ESBL-E carriers are asymptomatic. The study tested the hypothesis that residents with ESBL-E carriage may accumulate inside geriatric LTCFs through potential cross-transmission after exposure to residents with prolonged ESBL-E carriage. 260 residents from four Japanese LTCFs underwent ESBL-E testing of fecal specimens and were divided into two cohorts: Cohort 1,75 patients with ≥ 2 months residence at study onset; Cohort 2, 185 patients with < 2 months residence at study onset or new admission during the study period. Three analyses were performed: (1) ESBL-E carriage statuses in Cohort 1 and Cohort 2; (2) changes in ESBL-E carriage statuses 3-12 months after the first testing and ≥ 12 months after the second testing; and (3) lengths of positive ESBL-E carriage statuses. Compared with the residents in Cohort 1, a significantly larger proportion of residents in Cohort 2 were positive for ESBL-E carriage (28.0% in Cohort 1 vs 40.0% in Cohort 2). In the subsequent testing results, 18.3% of residents who were negative in the first testing showed positive conversion to ESBL-E carriage in the second testing, while no patients who were negative in the second testing showed positive conversion in the third testing. The maximum length of ESBL-E carriage was 17 months. The findings indicated that some residents acquired ESBL-E through potential cross-transmission inside the LTCFs after short-term residence. However, no residents showed positive conversion after long-term residence, which indicates that residents with ESBL-E carriage may not accumulate inside LTCFs. Practical infection control and prevention measures could improve the ESBL-E prevalence in geriatric LTCFs.

Population pharmacokinetics of continuous infusion of piperacillin/tazobactam in very elderly hospitalized patients and considerations for target attainment against Enterobacterales and Pseudomonas aeruginosa. Int J Antimicrob Agents 2021; 58:106408. [PMID: 34314808 DOI: 10.1016/j.ijantimicag.2021.106408] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 07/01/2021] [Accepted: 07/17/2021] [Indexed: 10/20/2022]
Abstract
Continuous infusion (CI) piperacillin/tazobactam is frequently used to treat infections in very elderly patients. This study aimed to conduct a population pharmacokinetic analysis of CI piperacillin/tazobactam, and to identify optimal dosages for safe and effective probability of target attainment (PTA) against Enterobacterales and Pseudomonas aeruginosa. Non-linear mixed-effects modelling was performed with Pmetrics. Monte Carlo simulations assessed the steady-state concentration (Css) of increasing piperacillin/tazobactam regimens (from 2.25 to 18 g daily by continuous infusion). Permissible doses were defined as those associated with <10% probability of Css >157.2 mg/L. PTA at the pharmacodynamic targets of free plasma steady-state concentration (fCss)/minimum inhibitory concentration (MIC) ≥1 and ≥4 and cumulative fraction of response (CFR) against EUCAST MIC distribution were also calculated. A total of 141 patients (median age 85 years) provided 217 plasma piperacillin Css. Most patients (55.2%) had hospital-acquired pneumonia and intra-abdominal infections. A one-compartment pharmacokinetic model with parallel linear and Michaelis-Menten elimination best described piperacillin data. Creatinine clearance (CLCR) was the covariate retained by the model. Pharmacokinetic estimates were 6.05 L/h for clearance and 3.39 mg/L for the Michaelis-Menten constant. Permissible doses were up to 4.5, 9, 11.25 and 13.5 g daily by continuous infusion for patients with CLCR of 0-19, 20-39, 40-59 and 60-79 mL/min/1.73 m2, respectively. At the clinical breakpoint of 8 mg/L, the permissible doses only achieved optimal PTA for fCss/MIC ≥1 in patients with CLCR 20-79 mL/min/1.73 m2. Optimal CFRs with the permissible doses were only attained against Escherichia coli and Proteus mirabilis. Permissible dosages and CLCR should be considered for prescribing CI piperacillin/tazobactam in very elderly patients.

Epidemiology and Prevention of Healthcare-Associated Infections in Geriatric Patients: A Narrative Review. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18105333.

Abstract
Demographic studies show that life expectancy is increasing in developed countries; increased longevity has also increased the share of the older population with often concomitant chronic conditions. An ageing population and increased comorbidities lead to more complex pharmacological therapies (polypharmacy). The particular picture provided by chronic conditions and polypharmacy can lead to longer hospital stays and a greater need for healthcare. Elderly patients are identified as being in the high-risk group for the development of healthcare-associated infections (HAIs) due to the age-related decline of the immune system, known as immunosenescence. Comorbid conditions can often complicate infections, diminishing our ability to treat them effectively. Respiratory tract infections are the most common healthcare-associated infections, followed by urinary tract infections. HAIs in geriatric patients are responsible for longer hospital stays, extended antibiotic therapy, significant mortality, and higher healthcare costs. This is because the microorganisms involved are multidrug-resistant and, therefore, more difficult to eliminate. Moreover, geriatric patients are frequently transferred from one facility (nursing homes, skilled nursing facilities, home care, and other specialty clinics) to another or from one hospital ward to another; these transitions cause care fragmentation, which can undermine the effectiveness of treatment and allow pathogens to be transferred from one setting to another and from one person to another. Multifactorial efforts such as early recognition of infections, restricted use of invasive devices, and effective infection control measures (surveillance, isolation practices, hand hygiene, etc.) can contribute to significant reduction of HAIs in geriatric patients.

Abstract
BACKGROUND Estimates on the incidence rates of infections are needed to assess the burden of disease in the community. OBJECTIVE To assess incidence rates of potentially serious infections in patients aged 65 years and over presenting to Flemish general practice from 2000 to 2015, and to describe patient characteristics. METHODS We performed a retrospective study, based on data provided by the Intego morbidity registry of the KU Leuven, which includes the electronic medical records of 111 general practitioners. Incidence rates were calculated taking person-time at risk into account, and longitudinal trends from 2000 to 2015 were analysed using autoregressive time-series analyses. RESULTS On average, a person aged 65 years or older has an 8.0% risk of getting a potentially serious infection each year. Acute cystitis was the most often occurring potentially serious infection [39.8/1000 person-years; 95% confidence interval (CI): 39.4-40.2], followed by influenza like illness (ILI, 24.3/1000 person-years; 95% CI: 24.0-24.6) and pneumonia (9.7/1000 person-years; 95% CI: 9.5-9.9). The incidence rates of pneumonia were higher in older age groups and in men, whereas they were markedly lower for ILI at older ages, in both genders. From 2000 to 2015, overall incidence rates decreased significantly for ILI, while they increased in women for pneumonia, acute cystitis and pyelonephritis. Common chronic comorbidities were non-insulin dependent diabetes, chronic obstructive pulmonary disease, asthma, heart failure and chronic renal insufficiency. CONCLUSIONS Potentially serious infections are quite common in an older patient population presenting to primary care. They are accompanied by several chronic comorbidities, which may differ by infection type.

Luo Y, Tixier EN, Grinspan AM. Fecal Microbiota Transplantation for Clostridioides difficile in High-Risk Older Adults Is Associated with Early Recurrence. Dig Dis Sci 2020; 65:3647-3651. [PMID: 32078714 DOI: 10.1007/s10620-020-06147-z] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Accepted: 02/11/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Fecal microbiota transplantation (FMT) is highly effective for treating recurrent Clostridioides difficile infection (CDI). CDI disproportionately affects the elderly; however, there is a paucity of data on FMT effectiveness in older adults, especially subpopulations at highest risk for CDI-related morbidity and mortality. AIM To assess the efficacy and safety of FMT for CDI in older adults. METHODS A retrospective, long-term follow-up study was performed. The high-risk subpopulation included patients who were immunocompromised, patients with inflammatory bowel disease, and patients presenting with severe or fulminant colitis. Outcome measures included primary cure rates, early (< 12 weeks) and late (> 12 weeks) recurrence rates, adverse events, and subgroup analysis of higher-risk populations. RESULTS Our cohort included 75 patients (72% female) with a mean age of 76.4 and Charlson comorbidity index score of 5.4. There were 34 patients in our higher-risk subpopulation as defined above with an adjusted recurrence rate of 32.1%. FMT was performed for severe or fulminant disease in 30.6% of patients with a 3-month survival rate of 73.9%. Overall, the adjusted primary cure rate was 67.2% and the adjusted CDI recurrence was 29.9% in our cohort (90% of recurrences occurred early). Most adverse events in our study were rehospitalizations for recurrent CDI. CONCLUSION Compared with previous studies of FMT efficacy, our cohort had a lower primary cure rate and higher CDI recurrence rate than previously reported, likely driven by our higher-risk subpopulations. Nevertheless, FMT should be considered early to prevent progression of CDI severity and recurrence, especially in patients who present with severe and fulminant disease.

Abstract
Older adults are more susceptible to viral and bacterial infection, and experience higher incidence and severity of infectious diseases. Although vaccination is the most logical solution in preventing infectious diseases, primary vaccine responses in individuals aged ≥65 years-old fail to generate complete protection. This is presumably attributed to immunosenescence, a term that describes functional differences associated with the immune system and natural age advancement. Both the innate and adaptive immune systems experience age-related impairments that contribute to insufficient protection following vaccination. This review addresses current knowledge of age-related changes that affect vaccine responsiveness; including the deficits in innate cell functions, dampened humoral and cell-mediated immune responses, current vaccination schedules for older adults, and concludes with potential strategies for improving vaccine efficacy specifically for this age group. Due to an age-related decline in immunity and poor vaccine responses, infectious diseases remain a burden among the aged population.

Association between length of residence and prevalence of MRSA colonization among residents in geriatric long-term care facilities. BMC Geriatr 2020; 20:481. [PMID: 33208107 PMCID: PMC7672839 DOI: 10.1186/s12877-020-01885-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 11/09/2020] [Indexed: 12/17/2022] Open
Abstract
Background A high prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization has been reported among residents in geriatric long-term care facilities (LTCFs). Some studies indicate that MRSA might be imported from hospitals into LTCFs via resident transfer; however, other studies report that high MRSA prevalence might be caused by cross-transmission inside LTCFs. We aimed to assess which factors have a large impact on the high MRSA prevalence among residents of geriatric LTCFs. Methods We conducted a cohort study among 260 residents of four geriatric LTCFs in Japan. Dividing participants into two cohorts, we separately analyzed (1) the association between prevalence of MRSA carriage and length of LTCF residence (Cohort 1: n = 204), and (2) proportion of residents identified as MRSA negative who were initially tested at admission but subsequently identified as positive in secondary testing performed at ≥2 months after their initial test (Cohort 2: n = 79). Results Among 204 residents in Cohort 1, 20 (9.8%) were identified as positive for MRSA. Compared with residents identified as MRSA negative, a larger proportion of MRSA-positive residents had shorter periods of residence from the initial admission (median length of residence: 5.5 vs. 2.8 months), although this difference was not statistically significant (p = 0.084). Among 79 residents in Cohort 2, 60 (75.9%) were identified as MRSA negative at the initial testing. Of these 60 residents, only one (1.7%) had subsequent positive conversion in secondary MRSA testing. In contrast, among 19 residents identified as MRSA positive in the initial testing, 10 (52.6%) were negative in secondary testing. Conclusions The prevalence of MRSA was lower among residents with longer periods of LTCF residence than among those with shorter periods. Furthermore, few residents were found to become MRSA carrier after their initial admission. These findings highlight that MRSA in LTCFs might be associated with resident transfer rather than spread via cross-transmission inside LTCFs.

Is the subcutaneous route an alternative for administering ertapenem to older patients? PHACINERTA study. J Antimicrob Chemother 2020; 74:3546-3554.

Abstract
BACKGROUND Antibiotic administration by subcutaneous (SC) injection is common practice in French geriatric wards as an alternative to the intravenous (IV) route, but few pharmacokinetic/pharmacodynamic data are available. Ertapenem is useful for the treatment of infections with ESBL-producing enterobacteria. OBJECTIVES To report and compare ertapenem pharmacokinetic data between IV and SC routes in older persons. METHODS Patients >65 years of age receiving ertapenem (1 g once daily) for at least 48 h (IV or SC, steady-state) were prospectively enrolled. Total ertapenem concentrations [residual (C0), IV peak (C0.5) and SC peak (C2.5)] were determined by UV HPLC. Individual-predicted AUC0-24 values were calculated and population pharmacokinetic analyses were performed. Using the final model, a Monte Carlo simulation involving 10 000 patients evaluated the influence of SC or IV administration on the PTA. Tolerance to ertapenem and recovery were also monitored. ClinicalTrials.gov identifier: NCT02505386. RESULTS Ten (mean ± SD age=87±7 years) and 16 (age=88±5 years) patients were included in the IV and SC groups, respectively. The mean C0 and C2.5 values were not significantly different between the IV and SC groups (C0=12±5.9 versus 12±7.4 mg/L, P=0.97; C2.5=97±42 versus 67±41 mg/L, P=0.99). The mean C0.5 was higher in the IV group compared with the SC group (C0.5=184±90 versus 51±66 mg/L, P=0.001). The mean individual AUCs (1126.92±334.99 mg·h/L for IV versus 1005.3±266.0 mg·h/L for SC, P=0.38) and PTAs were not significantly different between groups. No severe antibiotic-related adverse effects were noted. CONCLUSIONS SC administration of ertapenem is an alternative to IV administration in older patients.

Abstract
BACKGROUND Tuberculous meningitis (TBM) occurs in 1-5% of cases of tuberculosis. Without early treatment, mortality and permanent disability rates are high. METHODS A retrospective study performed at a tertiary hospital in Madrid (Spain) to describe clinical, diagnostic, and therapeutic aspects of TBM and analyze epidemiological trends over forty years, divided into two intervals (1979-1998 and 1999-2018). RESULTS Overall, TBM was diagnosed in 65 patients (1.8% of new tuberculosis diagnoses), 48 in the first period and 17 in the second one. Median age at diagnosis increased from 38.5 to 77 years (p = 0.003). The proportion of non-HIV immunosuppressed patients increased (from 2.1% to 29.4%, p < 0.001), while the percentage of patients with a history of drug-abuse decreased (from 33.3% to 5.9%, p = 0.027). The median time between the onset of neurological symptoms and lumbar puncture increased from seven to 15 days (p = 0.040). The time between the onset of symptoms and the initiation of tuberculostatic treatment also increased from eleven to 18 days (p = 0.555). Results from image, biochemical, and microbiological tests showed no differences between both periods. A decreasing trend was observed in survival rates at 1-week (from 97.9% to 64.7%, p < 0.001), 1-month (from 91.7% to 58.8%, p = 0.002) and 1-year (from 85.4% to 47.1%, p = 0.002) after TBM diagnosis. CONCLUSIONS The profile of patients diagnosed with TBM has changed from a young HIV-infected patient with a history of drug addiction to an elderly patient with non-HIV immunosuppression. Diagnosis and start of treatment both experienced a noticeable delay in the second period, which could help explain the increase in mortality observed across the two periods.

Abstract
OBJECTIVES To describe the rationale for subcutaneous (SC) administration of antibiotics from available published data and to make propositions to help clinicians in daily practice. DESIGN Narrative review. SETTING AND PARTICIPANTS Hospitalized patients, persons in long-term care facilities and ambulatory care. METHODS We searched the MEDLINE/PubMed electronic database for evidence supporting SC administration of antibiotics up to September 2019; the results of this primary search were supplemented by searching the references of the identified articles, as well as by searching in Google Scholar. RESULTS Regarding tolerability, efficacy, and pharmacokinetic/pharmacodynamic profiles, most studies suggest that the SC route could be an alternative to the intravenous route, particularly for time-dependent antibiotics and among certain patient populations, such as patients with poor venous access, swallowing disorders, or behavioral disturbance. However, clinical evidence of the benefits and risks of SC antibiotic administration is still scarce and of low level. CONCLUSIONS AND IMPLICATIONS SC administration of antibiotics may be useful in various settings such as in hospitalized patients and among those in long-term care facilities or being cared for at home. However, further clinical studies are needed to assess the pharmacokinetic/pharmacodynamic properties, as well as the risks and benefits of SC administration of antibiotics. In this review, we highlight the potential benefits of SC administration of antibiotics and address practical recommendations for its use. This information will enable improvement of treatment strategies and present the SC route as a potential option in specific situations.

Abstract
Early recognition and prompt treatment of a serious infection is important to optimize prognosis in older patients. The current evidence base underpinning this early recognition in ambulatory care is scattered and haphazard, calling for new research to strengthen clinical practice. Before embarking on such studies, it is important to seek consensus on what constitutes a serious infection in older patients presenting to ambulatory care. We conducted a 4-round e-Delphi study seeking consensus among medical professionals who deliver clinical care to older patients using online questionnaires and feedback. Twenty-two specialists in emergency care, general practice, geriatrics, and infectious diseases from 10 different countries participated in our study. We constructed 18 statements from the answers to the open questions in round 1, which were then rated by the participants in 2 consecutive rounds. After assessing the level of agreement, consensus, and stability, the following definition was preferred by 94% of the participants: "A serious infection in a geriatric patient presenting to ambulatory care is an infection with a high risk of complications, functional decline, and/or mortality, requiring a prompt diagnostic and therapeutic approach in the appropriate care setting. The most important determinants of the choice of setting are the level of emergency, the geriatric profile of the patient (frailty status, functional status, and comorbidities), and the patients' level of autonomy and personal preferences. Factors such as the feasibility of home care, the potential consequences of delayed or suboptimal treatment and infection specific treatment requirements should be weighed as well when choosing the appropriate care setting." Based on consensus among 22 clinicians working in 10 different countries, we propose a definition for serious infections in geriatric patients presenting to ambulatory care. This will form the basis of future studies in this domain.

Abstract
BACKGROUND Clostridioides difficile infections (CDIs) have been identified as a major health concern due to the high morbidity, mortality, and cost of treatment. The aim of this study was to review the extant literature and identify the various patient-related, medication-related, and organizational risk factors associated with developing hospital-acquired CDIs in adult patients in the United States. METHODS A systematic review of four (4) online databases, including Scopus, PubMed, CINAHL, and Cochrane Library, was conducted to identify empirical studies published from 2007 to 2017 pertaining to risk factors of developing hospital-acquired CDIs. FINDINGS Thirty-eight studies (38) were included in the review. Various patient-level and medication-related risk factors were identified including advanced patient age, comorbidities, length of hospital stay, previous hospitalizations, use of probiotic medications and proton pump inhibitors. The review also identified organizational factors such as room size, academic affiliation, and geographic location to be significantly associated with hospital-acquired CDIs. CONCLUSION Validation of the factors associated with high risk of developing hospital-acquired CDIs identified in this review can aid in the development of risk prediction models to identify patients who are at a higher risk of developing CDIs and developing quality improvement interventions that might improve patient outcomes by minimizing risk of infection.

Abstract
Evaluate risk factors for cytomegalovirus (CMV) reactivation during the first year after kidney transplantation in the CMV-seropositive older recipient. Retrospective single-center study. Between 2011 and 2015, 91 patients ≥ 65 years received a kidney transplant; these were matched with 91 controls, aged 40-60. Risk of CMV reactivation in the CMV-seropositive recipients was analyzed. Sixty-three older and 54 younger recipients were included; 50% had received CMV-directed prophylaxis. CMV reactivation was significantly more frequent in the older group (71.4% vs 44.4%, p = 0.003) and occurred earlier (p = 0.003). A multivariate model showed that only age was associated with CMV reactivation (OR 2.48, p = 0.03). After excluding patients that received thymoglobulin, older age group remained the only risk factor of CMV reactivation (OR 3.81, p = 0.014). Recurrent event analysis showed that the older cohort had an HR of 1.94 (p = 0.01) of CMV viremia; there was significant episode-cohort interaction (p < 0.01). While the older group had a higher risk of infection (HR = 2.43), after the initial episode the relative hazards were approximately equal (HR = 1.08, at period 2). This suggests that it is key to specifically avoid the first episode of reactivation. Universal prophylaxis or a hybrid prophylaxis model should be considered in the CMV-seropositive kidney transplant recipient aged ≥ 65 years.

Abstract
Background/aim Community-onset urinary tract infections(UTIs) caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli have increased in many parts of the world. This study aimed to determine the prevalence and risk factors for community-onset UTI caused by ESBL-producing E. coli. Materials and methods This prospective cohort study was conducted between January 2012 and March 2014 in cases of community-onset UTI caused by E. coli. Patients with UTI due to ESBL-producing E. coli and patients with UTI due to non-ESBL-producing E. coliwere compared to identify risk factors for ESBL-producing E. coli in the community. Results A total of 305 patients (116 males [46.4%]; mean age: 57.76 ± 18.06 years) were included in the study. Among these patients, 154 (50.5%) were infected with ESBL-producing E. coli. In multivariate analysis, the healthcare-associated UTI (odds ratio [OR]: 1.80; 95% confidence interval [CI]: 1.02–3.18; P = 0.041), upper urinary tract infection (OR: 3.05; 95% CI: 1.76–5.29; P < 0.0001), use of antibiotics in the preceding 6 months (OR: 2.28; 95% CI: 1.21–4.30; P = 0.011), and having two or more risk factors (OR: 4.03; 95% CI: 1.73–9.35; P = 0.001) were the significant factors associated with increased risk of community-onset UTIs due to ESBL-producing E. coli. Conclusion The increasing prevalence ofESBL-producing E. coli makes it difficult to decide the empirical therapy in UTIs, especially in patients with two or more of the risk factors. A better understanding of the epidemiology and risk factors associated with community-onset UTIs due to ESBL-producing E. coli may have significant implications in decision-making for empirical antimicrobial treatment.

BMC Geriatr 2019; 19:210. [PMID: 31382895 PMCID: PMC6683564 DOI: 10.1186/s12877-019-1236-6] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2019] [Accepted: 07/30/2019] [Indexed: 11/22/2022] Open
Abstract
Background Respiratory infections among older adults in long-term care facilities (LTCFs) are a major global concern, yet a rigorous systematic synthesis of the literature on the burden of respiratory infections in the LTCF setting is lacking. To address the critical need for evidence regarding the global burden of respiratory infections in LTCFs, we assessed the burden of respiratory infections in LTCFs through a systematic review of the published literature. Methods We identified articles published between April 1964 and March 2019 through searches of PubMed (MEDLINE), EMBASE, and the Cochrane Library. Experimental and observational studies published in English that included adults aged ≥60 residing in LTCFs who were unvaccinated (to identify the natural infection burden), and that reported measures of occurrence for influenza, respiratory syncytial virus (RSV), or pneumonia were included. Disagreements about article inclusion were discussed and articles were included based on consensus. Data on study design, population, and findings were extracted from each article. Findings were synthesized qualitatively. Results A total of 1451 articles were screened for eligibility, 345 were selected for full-text review, and 26 were included. Study population mean ages ranged from 70.8 to 90.1 years. Three (12%) studies reported influenza estimates, 7 (27%) RSV, and 16 (62%) pneumonia. Eighteen (69%) studies reported incidence estimates, 7 (27%) prevalence estimates, and 1 (4%) both. Seven (27%) studies reported outbreaks. Respiratory infection incidence estimates ranged from 1.1 to 85.2% and prevalence estimates ranging from 1.4 to 55.8%. Influenza incidences ranged from 5.9 to 85.2%. RSV incidence proportions ranged from 1.1 to 13.5%. Pneumonia prevalence proportions ranged from 1.4 to 55.8% while incidence proportions ranged from 4.8 to 41.2%. Conclusions The reported incidence and prevalence estimates of respiratory infections among older LTCF residents varied widely between published studies. The wide range of estimates offers little useful guidance for decision-making to decrease respiratory infection burden. Large, well-designed epidemiologic studies are therefore still necessary to credibly quantify the burden of respiratory infections among older adults in LTCFs, which will ultimately help inform future surveillance and intervention efforts.

Abstract
Infections are leading causes of morbidity and mortality in the advanced aged. Various factors including immunosenescens, comorbid chronic diseases, and alterations in normal physiological organ functions may modify the frequency and severity of infections in elderly patients. Normal body reactions to ensuing infection, such as increased body temperature, may be blunted in those patients causing difficulties in differential diagnosis between infection and other diseases. In severe infections the respiratory and urinary tracts are the most frequently involved systems which may be accompanied by severe sepsis. Bacteremia and sepsis are also associated with indwelling vascular catheters in the elderly who are admitted to the intensive care unit (ICU). Older patients are more vulnerable to the Clostridioides difficile infection, as well. Although the general management of infections in severely ill elderly patients is not different than in younger patients, meticulous care in fluid management and careful individualized optimization in antibiotic therapy, along with the other principals of antimicrobial stewardship are warranted in order to prevent increased mortality caused by infection. Organized team management when treating critically ill elderly patients in the ICU is essential and will reduce the morbidity and mortality due to infection in such patients.

Abstract
Infections threaten successful outcomes after kidney transplantation. Our aim was to determine if the number, types of infections and the risk factors for common infections differed between older compared to younger kidney transplant (KT) recipients in the first year after surgery. We performed a single-center retrospective cohort study. Between 2011 and 2015, 91 KTs were performed in patients ≥65 years of age; these were matched 1:1 (by year of transplantation, sex and race) to controls aged 40-60 years. Over 90% of both groups had an infectious complication. Urinary tract infections (UTIs) and cytomegalovirus (CMV) viremia were significantly more frequent in older recipients. Older adults had more late onset UTIs, including after stent removal. CMV viremia was more frequent in older adults in the 1-6 months post-transplant period. Due to our center-specific protocol utilizing pre-emptive monitoring in the CMV recipient-seropositive population, the higher CMV incidence in the aged recipient was driven by this subpopulation of older adults. No difference in pneumonias or bloodstream infections were found, nor in surgical complications, rejection or graft loss. Mortality was higher at 1-year post-transplant in the older recipients (9.9% vs 1.1%; P = 0.018). Prophylactic and immunosuppressive strategies may need to be altered for older KT recipients.

Abstract
In the U.S., older adults aged 65 or above comprise nearly one quarter of the solid organ transplant (SOT) waitlists, and the number of transplants performed in this age group continues to increase. There are no specific guidelines for the assessment and follow up of the older SOT candidate or recipient. Older adults are at increased risk of infectious complications after SOT. Despite these complications and even with the use of suboptimal donors, overall outcomes are favorable. We provide an overview to specific consideration as they relate to the older SOT candidate and recipient.

Abstract
Considering an increase in the life expectancy leading to a rise in the elderly population, it is important to recognize the changes that occur along the process of aging. Gastrointestinal (GI) changes in the elderly are common, and despite some GI disorders being more prevalent in the elderly, there is no GI disease that is limited to this age group. While some changes associated with aging GI system are physiologic, others are pathological and particularly more prevalent among those above age 65 years. This article reviews the most important GI disorders in the elderly that clinicians encounter on a daily basis. We highlight age-related changes of the oral cavity, esophagus, stomach, small and large bowels, and the clinical implications of these changes. We review epidemiology and pathophysiology of common diseases, especially as they relate to clinical manifestation in elderly. Details regarding management of specific disease are discussed in detail if they significantly differ from the management for younger groups or if they are associated with significant challenges due to side effects or polypharmacy. Cancers of GI tract are not included in the scope of this article.

Abstract
In order to elucidate the causes for the increased mortality of aged patients with bacterial central nervous system (CNS) infections, we compared the course of Streptococcus pneumoniae (S. pneumoniae) meningitis in aged and young mice. Aged (21.2 ± 3.1 months, n = 40) and young (3.2 ± 0.9 months, n = 42) C57BL/6N and B6/SJL mice were infected by intracerebral injection of 50–70 CFU S. pneumoniae serotype 3 and monitored for 15 days. Aged and young mice did not differ concerning mortality (35% versus 38%), weight loss, development of clinical symptoms, bacterial concentrations in cerebellum and spleen as well as the number of leukocytes infiltrating the CNS. In contrast to results from our geriatric mouse model of Escherichia coli (E. coli) meningitis, where aged mice showed a higher mortality and an impaired elimination of bacteria, we did not find any differences between aged and young mice after intracerebral infection with S. pneumoniae serotype 3. This indicates that the increased susceptibility of aged mice to bacterial CNS infections is pathogen-specific: It appears less prominent in infections caused by hardly phagocytable pathogens with thick capsules like S. pneumoniae serotype 3, where the age-related decline of the phagocytic capacity of microglia and macrophages has a minor influence on the disease course.

Abstract
The diagnosis, treatment, and prevention of infectious diseases in older adults in long-term care facilities (LTCFs), particularly nursing facilities, remains a challenge for all health providers who care for this population. This review provides updated information on the currently most important challenges of infectious diseases in LTCFs. With the increasing prescribing of antibiotics in older adults, particularly in LTCFs, the topic of antibiotic stewardship is presented in this review. Following this discussion, salient points on clinical relevance, clinical presentation, diagnostic approach, therapy, and prevention are discussed for skin and soft tissue infections, infectious diarrhea (Clostridium difficile and norovirus infections), bacterial pneumonia, and urinary tract infection, as well as some of the newer approaches to preventive interventions in the LTCF setting.

Abstract
The burden of Clostridium difficile infection (CDI) is profound and growing. CDI now represents a common cause of health care–associated diarrhea, and is associated with significant morbidity, mortality, and health care costs. CDI disproportionally affects the elderly, possibly explained by the following risk factors: age-related impairment of the immune system, increasing antibiotic utilization, and frequent health care exposure. In the USA, recent epidemiological studies estimate that two out of every three health care–associated CDIs occur in patients 65 years or older. Additionally, the elderly are at higher risk for recurrent CDI. Existing therapeutic options include metronidazole, oral vancomycin, and fidaxomicin. Choice of agent depends on disease severity, history of recurrence, and, increasingly, the drug cost. Bezlotoxumab, a recently approved monoclonal antibody targeting C. difficile toxin B, offers an exciting advancement into immunologic therapies. Similarly, fecal microbiota transplantation is gaining popularity as an effective option mainly for recurrent CDI. The challenge of decreasing CDI burden in the elderly involves adopting preventative strategies, optimizing initial treatment, and decreasing the risk of recurrence. Expanded strategies are certainly needed to improve outcomes in this high-risk population. This review considers available data from prospective and retrospective studies as well as case reports to illustrate the merits and gaps in care related to the management of CDI in the elderly.
