RESUMEN
Altered mental status (AMS) is a common symptom in geriatric patients, especially in the long-term care setting. Traditionally, AMS has been associated with urinary tract infections (UTIs) in older people. However, data correlating UTIs with AMS are lacking. For this reason, asymptomatic bacteriuria (ASB) guidelines do not recommend using non-specific symptoms, such as AMS, to indicate a potential diagnosis of UTI. It is important to distinguish between colonization and infection, which can be done through proper interpretation of a urine analysis in the presence of UTI-specific symptomatology. In the absence of UTIspecific symptoms, alternative diagnoses for AMS should be explored. Consultant pharmacists are a key stakeholder and partner in ensuring appropriate antimicrobial prescribing practices, including identification of ASB in older patients.

INTRODUCTION: Studies have suggested that in addition to antimicrobials, some non-antibiotics may alter the gut microbiome. This systematic review sought to determine if there is an association between immunosuppressive agents used in recipients of solid organ transplants (SOT) and alterations in the gut microbiome. METHODS: English language PubMed and Scopus searches were conducted to identify relevant articles. Inclusion criteria were defined as pertaining to solid organ transplantation, immunosuppression, and the gut microbiome. Articles were excluded if they contained only genetic microbiota descriptions, narrative reviews of bacteria, or described bacteria as a pathogen for infections. PRISMA reporting was used to guide this literature review. RESULTS: A preliminary search identified 665 articles, of which 75 articles met the inclusion criteria, and 10 articles remained after application of exclusion criteria. Seventy-one percent of articles discussed calcineurin inhibitors, such as tacrolimus, 38% included mycophenolate mofetil, and 52% included steroids, such as prednisone. Some studies utilized a combination of immunosuppressants or had multiple study arms. Seventy percent of the articles indicated changes in quantities of anaerobic bacteria including Ruminococcaceae, Lachnospiraceae, Firmicutes, Bacteroides, and Clostridiales. Combinations of immunosuppressant agents were associated with an increase in colonization of Escherichia coli and Enterococcus sp. CONCLUSION: Some immunosuppressants are associated with changes in gut flora, but the impact on clinical outcomes is unknown. Robust clinical trials delineating the direct effect of immunosuppressants on the gut microbiome as well as the impact on clinical outcomes are warranted.

INTRODUCTION: The objective of this article is to describe the efforts of the student pharmacist organization called Know Your Medicine (KYM) as they conduct medication therapy management (MTM) for older adults and underserved communities. METHODS: Patients brought medications, immunization records, and health concerns to KYM events during academic years 2012-2013 and 2013-2014. Student pharmacists performed health screenings, created personalized medication records (PMR), made recommendations, created personal action plans (PAP), and conducted follow-up phone calls. RESULTS: Student pharmacists provided MTM services for a total of 107 patients. The mean duration of a KYM appointment was 62±21min, and student pharmacists provided a mean of 3.5±2.1 recommendations per patient. Patients had a mean age of 78±11 years, 4.5±3.2 disease states, 6.9±4.6 prescriptions, 1.9±1.9 OTC medications, and 2.8±2.6 vitamins or herbals. At the time of the follow-up phone call, a mean of 2.6±1.9 recommendations per patient had been followed. DISCUSSION AND CONCLUSIONS: Student pharmacists successfully implemented a new MTM program for older adults and underserved communities. This program can serve as an example of how other pharmacy colleges and schools might implement MTM training and real-world MTM experience for their student pharmacists.

BACKGROUND: It is standard practice to administer prophylactic antibiotics post lung transplantation. However, no studies have evaluated the impact of culture positivity. The purpose of this study was to evaluate early post-transplant outcomes of culture-positive and culture-negative lung transplant (LT) recipients and the appropriateness of the empiric regimens used. METHODS: Adult patients who received an LT at Emory University Hospital between January 1, 2010 and August 31, 2015 were reviewed and stratified into three groups: (i) culture-positive appropriate empiric treatment, (ii) culture-positive inappropriate empiric treatment, and (iii) culture-negative. Antibiotics were defined as appropriate if bacteria were sensitive to the empiric regimen. The primary endpoint was 30-day mortality. Secondary endpoints included hospital length of stay (LOS), intensive care unit (ICU) LOS, percent neutrophil count in a bronchoalveolar lavage (BAL) sample, presence of airway ischemia, and appropriateness of the empiric antibiotic regimen. RESULTS: Nine, zero, and four patients died within 30 days in the culture-positive appropriate (n = 113), culture-positive inappropriate (n = 5), and culture-negative groups (n = 29) (P = .564) respectively. The median hospital LOS was 19, 16, and 15 days respectively. Median ICU LOS was 6, 5, and 7 respectively. The respective percent neutrophil counts in the BAL fluid were 79, 83, and 65. The presence of airway ischemia was only documented in eight patients, all in the culture-positive appropriate group. CONCLUSION: We did not identify an association between antibiotic appropriateness and 30-day mortality, hospital LOS, or ICU LOS in post-LT recipients.

INTRODUCTION: Diabetic foot infections (DFIs) are the leading cause of non-traumatic lower extremity amputations in the United States. Antimicrobials active against methicillin-resistant Staphylococcus aureus (MRSA) are recommended in patients with associated risk factors; however, limited data exist to support these recommendations. Due to the changing epidemiology of MRSA, and the consequences of unnecessary antibiotic therapy, guidance regarding the necessity of empirical MRSA coverage in DFIs is needed. We sought to 1) describe the prevalence of MRSA DFIs at our institution and compare to the proportion of patients who receive MRSA antibiotic coverage and 2) identify risk factors for MRSA DFI. METHODS: This was a retrospective cohort study of all adult, culture-positive DFI patients managed at University Hospital, San Antonio, TX between January 1, 2010 and September 1, 2014. Patient eligibility included a principal ICD-9-CM discharge diagnosis code for foot infection and a secondary diagnosis of diabetes. The primary outcome was MRSA identified in the wound culture. Independent variables assessed included patient demographics, comorbidities, prior hospitalization, DFI therapies, prior antibiotics, prior MRSA infection, and laboratory values. Multivariable logistic regression was used to identify risk factors for MRSA DFI. RESULTS: Overall, 318 patients met inclusion criteria. Patients were predominantly Hispanic (79%) and male (69%). Common comorbidities included hypertension (76%), dyslipidemia (52%), and obesity (49%). S. aureus was present in 46% of culture-positive DFIs (MRSA, 15%). A total of 273 patients (86%) received MRSA antibiotic coverage, resulting in 71% unnecessary use. Male gender (OR 3.09, 95% CI 1.37-7.99) and bone involvement (OR 1.93, 1.00-3.78) were found to be independent risk factors for MRSA DFI. CONCLUSIONS: Although MRSA was the causative pathogen in a small number of DFI, antibiotic coverage targeted against MRSA was unnecessarily high.

BACKGROUND: The prevalence of diabetes has increased over the last 2 decades; however, the national incidence of diabetic foot infections (DFIs) in the United States is unknown. We sought to determine national trends in DFIs among hospitalized adults in the United States over 15 years. METHODS: This was a retrospective cohort study of the U.S. National Hospital Discharge Survey from 1996-2010. Adult patients with a principal diagnosis of foot infection and a secondary diagnosis of diabetes were identified using ICD-9-CM codes. Incidence was defined as DFI discharges per 100 diabetes discharges. Independent risk factors for DFI among diabetics were identified using multivariable logistic regression. RESULTS: These data represent 1,059,552 DFI discharges over the study period. The incidence of DFI decreased from 1996 (2.3 DFIs/100 diabetes discharges) to 2010 (1.1 DFI/100 diabetes discharges). The proportion of patients experiencing lower-extremity amputation declined from 33.2% in 1996 to 17.1% in 2010. Peripheral vascular disease (odds ratio [OR], 2.89; 95% confidence interval [CI], 2.87-2.91), peripheral neuropathy (OR, 2.62; 95% CI, 2.60-2.64), and male sex (OR, 1.67; 95% CI, 1.66-1.68) were the leading risk factors for DFI. CONCLUSION: The incidence of DFI among hospitalized adults in the United States declined by more than half from 1996-2010.
