Abstract
Importance Expansion of opioid use disorder treatment is needed, particularly in rural communities. Objective To evaluate technology-assisted buprenorphine (TAB) efficacy (1) over a longer period than previously examined, (2) with the addition of overdose education, and (3) among individuals residing in rural communities. Design, Setting, and Participants Two parallel, 24-week randomized clinical trials were conducted at the University of Vermont between February 1, 2018, and June 30, 2022. Participants were adults with untreated opioid use disorder from nonrural (trial 1) or rural (trial 2) communities. These trials are part of a programmatic effort to develop TAB protocols to improve treatment availability in underserved areas. Interventions Within each trial, 50 participants were randomized to TAB or control conditions. Participants in the TAB group completed bimonthly visits to ingest medication and receive take-home doses via a computerized device. They received nightly calls via an interactive voice response (IVR) system, IVR-generated random call-backs, and iPad-delivered HIV, hepatitis C virus (HCV), and overdose education. Control participants received community resource guides and assistance with contacting resources. All participants received harm reduction supplies and completed monthly assessments. Main Outcomes and Measures The primary outcome was biochemically verified illicit opioid abstinence across monthly assessments. Secondary outcomes included self-reported opioid use in both groups and abstinence at bimonthly and random call-back visits, treatment adherence, satisfaction, and changes in HIV, HCV, and overdose knowledge among TAB participants. Results Fifty individuals (mean [SD] age, 40.6 [13.1] years; 28 [56.0%] male) participated in trial 1, and 50 (mean [SD] age, 40.3 [10.8] years; 30 [60.0%] male) participated in trial 2. Participants in the TAB group achieved significantly greater illicit opioid abstinence vs controls at all time points in both trial 1 (85.3% [128 of 150]; 95% CI, 70.7%-93.3%; vs 24.0% [36 of 150]; 95% CI, 13.6%-38.8%) and trial 2 (88.0% [132 of 150]; 95% CI, 72.1%-95.4%; vs 21.3% [32 of 150]; 95% CI, 11.4%-36.5%). High abstinence rates were also observed at TAB participants' bimonthly dosing visits (83.0% [95% CI, 67.0%-92.0%] for trial 1 and 88.0% [95% CI, 71.0%-95.0%] for trial 2). Treatment adherence was favorable and similar between trials (with rates of approximately 99% for buprenorphine administration, 93% for daily IVR calls, and 92% for random call-backs), and 183 of 187 urine samples (97.9%) tested negative for illicit opioids at random call-backs. iPad-delivered education was associated with significant and sustained increases in HIV, HCV, and overdose knowledge. Conclusions and Relevance In these randomized clinical trials of TAB treatment, demonstration of efficacy was extended to a longer duration than previously examined and to patients residing in rural communities. Trial Registration ClinicalTrials.gov Identifier: NCT03420313.

Abstract
BACKGROUND People with opioid use disorder (OUD) are overrepresented in US correctional facilities and experience disproportionately high risk for overdose after release. Medications for OUD (MOUD) are highly efficacious but not available to most incarcerated individuals. In 2018, Vermont began providing MOUD for all incarcerated individuals with OUD statewide. In 2020, the COVID-19 state of emergency began. We assessed the impact of both events on MOUD utilization and treatment outcomes. METHODOLOGY Analyses linked Vermont Department of Corrections administrative data and Medicaid claims data between 07/01/2017 and 03/31/2021. The study used logistic regression to analyze treatment engagement among all incarcerated individuals in Vermont. Multilevel modeling assessed change in clinical outcomes among release episodes that occurred among individuals with an OUD diagnosis Medicaid claim. RESULTS Prescriptions for MOUD while incarcerated increased from 0.8% to 33.9% of the incarcerated population after MOUD implementation (OR = 67.4) and subsequently decreased with the onset of COVID-19 to 26.6% (OR = 0.7). After MOUD implementation, most prescriptions (63.1%) were to individuals who had not been receiving MOUD prior to incarceration, but this figure decreased to 53.9% with the onset of COVID-19 (OR = 0.7). Prescriptions for MOUD within 30 days after release increased from 33.9% of those with OUD before to 41.0% after MOUD implementation (OR = 1.4) but decreased to 35.6% with the onset of COVID-19 (OR = 0.8). Simultaneously, opioid-related nonfatal overdoses within 30 days after release decreased from 1.2% before to 0.8% after statewide MOUD implementation (OR = 0.3) but increased to 1.9% during COVID-19 (OR = 3.4). Fatal overdoses within 1 year after release decreased from 27 deaths before to ≤10 after statewide MOUD implementation and remained ≤10 during COVID-19. CONCLUSIONS This longitudinal evaluation demonstrated increased treatment engagement and a decrease in opioid-related overdose following implementation of MOUD in a statewide correctional system. In contrast, these improvements were somewhat attenuated with the onset of COVID-19, which was associated with decreased treatment engagement and an increase in nonfatal overdoses. Considered together, these findings demonstrate the benefits of statewide MOUD for incarcerated individuals as well as the need to identify and address barriers to continuation of care following release from incarceration in the context of COVID-19.

Abstract
OBJECTIVE Nearly all individuals with opioid use disorder (OUD) report lifetime trauma exposure and one-third meet diagnostic criteria for posttraumatic stress disorder (PTSD). Although prolonged exposure (PE) therapy is a first-line treatment for PTSD, little is known about the effects of PE in individuals with co-occurring OUD. Furthermore, its efficacy is commonly undermined by poor therapy attendance. This pilot study evaluated the feasibility and initial efficacy of a novel PE protocol for improving PE attendance and PTSD symptoms among buprenorphine- or methadone-maintained adults with PTSD. METHOD Thirty participants with co-occurring PTSD and OUD were randomized to receive either: (a) continued medications for OUD (MOUD) treatment as usual (TAU), (b) Prolonged Exposure therapy (PE), or (c) PE with financial incentives delivered contingent upon PE session attendance (PE+). Primary outcomes included PE session attendance, PTSD symptom severity, and use of opioids other than prescribed MOUD. RESULTS PE+ participants attended significantly more therapy sessions vs. PE (87% vs. 35%; p <.0001). PTSD symptom reductions were also significantly greater in the PE+ vs. TAU group (p =.046). Participants in the two PE conditions submitted significantly fewer urine samples that tested positive for opioids than TAU participants (0% vs. 22%; p =.007). CONCLUSIONS These findings provide preliminary support for the efficacy of PE+ for improving PE attendance and PTSD symptoms without prompting opioid relapse in individuals with co-occurring PTSD and OUD. These promising results justify a larger scale randomized clinical trial to more rigorously evaluate this novel treatment approach.

Abstract
Impulsivity is a key feature of opioid use disorder (OUD) and other psychiatric conditions, including posttraumatic stress disorder (PTSD). The relationship between disorders and impulsivity may be additive, such that individuals with multiple disorders exhibit greater impulsivity than those with a single disorder. However, the association between impulsivity, OUD, and PTSD is unclear. Accordingly, this study compared individuals with concurrent OUD and PTSD (OUD + PTSD; n = 55), OUD without PTSD (OUD-PTSD; n = 34), PTSD without OUD (n = 32), and healthy controls (HCs; n = 55) on the Short Urgency, Premeditation, Perseverance, Sensation Seeking, Positive Urgency Impulsive Behavior Scale (SUPPS-P), and the 27-item Monetary Choice Questionnaire (MCQ). With respect to the SUPPS-P, the OUD + PTSD, OUD-PTSD, and PTSD without OUD groups reported more impulsivity on the negative urgency, positive urgency, and lack of premeditation subscales compared to HCs (ps < .001). The OUD + PTSD group also reported greater negative urgency compared to the OUD-PTSD group (p = .001) and HCs (p < .001), but not the PTSD without OUD group (p = .07). Furthermore, participants with OUD + PTSD exhibited greater discounting of delayed rewards on the MCQ than those in the PTSD without OUD group and HCs (p's < .001). However, no significant differences were observed between the two OUD groups (p = .86). These results support impulsivity as a mechanism underlying both OUD and PTSD. Future research should examine whether interventions targeting impulsivity, emotion regulation, and delay discounting are associated with meaningful improvements in functioning among individuals with OUD and PTSD.

Abstract
Introduction Post-traumatic stress disorder (PTSD) and extra-medical opioid Use (EMOU) frequently co-occur. Few studies have examined the relationship between EMOU and social networks among people with PTSD. Accordingly, this study examined social networks in a sample of people with PTSD in the United States by assessing the association between social network size/diversity and lifetime EMOU status. Methods Data came from a cross-sectional, nationally representative sample of adults who participated in the National Epidemiologic Survey on Alcohol and Related Conditions-III (NESARC-III) from 2012 to 2013. For people with past-year PTSD (unweighted n = 1,764), social network size and diversity were estimated by lifetime EMOU status. Multivariable logistic regression models examined the association between social network size, diversity, and EMOU adjusting for sociodemographics, cigarette use, major depression, and anxiety disorder. Results Between 2012-2013, 24% of people with PTSD had lifetime EMOU. Those with EMOU had a lower social network size and diversity than individuals without EMOU (14 vs. 17 persons, 4 vs. 5 groups, p-values < 0.05). In adjusted models, EMOU was significantly associated with social network diversity (AOR = 0.91; 95% CI: 0.82, 0.99), but not with social network size (AOR = 1.00; 95% CI: 0.98, 1.01). Conclusions Less diverse social networks were associated with lifetime EMOU among people with PTSD. Future research should examine associations between the quality of social networks and EMOU, ideally from longitudinal studies.

Abstract
Posttraumatic stress disorder (PTSD) and opioid use disorder (OUD) may be associated with poor outcomes in rural areas where access to mental health services and opioid agonist treatment (OAT) is limited. This study examined the characteristics associated with a history of PTSD among a sample of individuals seeking buprenorphine treatment for OUD in Vermont, the second-most rural state in the US. Participants were 89 adults with OUD who participated in one of two ongoing randomized clinical trials examining the efficacy of an interim buprenorphine dosing protocol for reducing illicit opioid use during waitlist delays to OAT. Thirty-one percent of participants reported a history of PTSD. Those who did (PTSD+; n = 28) and did not (PTSD-; n = 61) report a history of PTSD were similar on sociodemographic and drug use characteristics. However, the PTSD+ group was less likely to have received prior OUD treatment compared to the PTSD- group (p = .02) despite being more likely to have a primary care physician (p = .009) and medical insurance (p = .002). PTSD+ individuals also reported greater mental health service utilization, more severe psychiatric, medical and drug use consequences, and greater pain severity and interference vs. PTSD- individuals (ps < 0.05). These findings indicate that a history of PTSD is prevalent and associated with worse outcomes among individuals seeking treatment for OUD in Vermont. Dissemination of screening measures and targeted interventions may help address the psychiatric and medical needs of rural individuals with OUD and a history of PTSD.

Abstract
OBJECTIVE Chronic non-cancer pain (CNCP) is prevalent among individuals with opioid use disorder (OUD). However, the impact of CNCP on buprenorphine treatment outcomes is largely unknown. In this secondary analysis, we examined treatment outcomes among individuals with and without CNCP who received a low-barrier buprenorphine maintenance regimen during waitlist delays to more comprehensive opioid treatment. METHODS Participants were 28 adults with OUD who received 12 weeks of buprenorphine treatment involving bimonthly clinic visits, computerized medication dispensing, and phone-based monitoring. At intake and monthly follow-up assessments, participants completed the Brief Pain Inventory, Beck Anxiety Inventory, Beck Depression Inventory (BDI-II), Brief Symptom Inventory (BSI), Addiction Severity Index, and staff-observed urinalysis. RESULTS Participants with CNCP (n = 10) achieved comparable rates of illicit opioid abstinence as those without CNCP (n = 18) at weeks 4 (90% vs 94%), 8 (80% vs 83%), and 12 (70% vs 67%) (P = 0.99). Study retention was also similar, with 90% and 83% of participants with and without CNCP completing the 12-week study, respectively (P = 0.99). Furthermore, individuals with CNCP demonstrated significant improvements on the BDI-II and Global Severity Index subscale of the BSI (P < 0.05). However, those with CNCP reported more severe medical problems and smaller reductions in legal problems relative to those without CNCP (P = 0.03). CONCLUSIONS Despite research suggesting that chronic pain may influence OUD treatment outcomes, participants with and without CNCP achieved similar rates of treatment retention and significant reductions in illicit opioid use and psychiatric symptomatology during low-barrier buprenorphine treatment.

Abstract
OBJECTIVE Although opioid maintenance is a first-line approach for treating opioid use disorder (OUD), suboptimal treatment outcomes have been reported among emerging adults (EAs; 18-25 years of age). In this secondary analysis, we compared treatment outcomes between EAs and older adults (OAs; ≥ 26 years of age) receiving low-barrier, technology-assisted Interim Buprenorphine Treatment (IBT) during waitlist delays to comprehensive opioid maintenance treatment. METHOD Participants were 35 individuals with OUD who received IBT consisting of 12-weeks of buprenorphine maintenance with bi-monthly clinic visits and technology-assisted monitoring. At monthly follow-up assessments, participants completed staff-observed urinalysis, the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), and Addiction Severity Index (ASI). RESULTS At study intake, EAs (n = 10) reported greater past-year intravenous drug use and greater employment, legal, and psychiatric severity (p's < .05) compared to OAs (n = 25). Despite these initial differences, there were no significant differences in the percentages of urine specimens testing negative for illicit opioids between EA and OA participants at Study Week 4 (90 % vs. 88 %, p = .99), Week 8 (80 % vs. 76 %, p = .99) or Week 12 (60 % vs. 68 %, p = .71). Relative to their older peers, EAs also demonstrated significantly greater improvements on the BAI, BDI-II, and ASI Employment and Legal subscales (p's < .05). CONCLUSIONS Despite presenting with greater past-year intravenous drug use and psychosocial severity relative to OAs, EAs responded favorably to the IBT intervention.

Abstract
Non-medical use of prescription opioids (NMUPO) and related overdoses are disproportionately elevated among young adults. Efforts to understand the underlying reasons for NMUPO are critical for developing more effective prevention and intervention strategies for this group. Given the robust literature on the association between educational status and substance abuse risk, we examined the reasons for NMUPO through the lens of educational attainment among young adults. Data from the 2016 National Survey on Drug Use and Health came from an unweighted sample of 941 young adults aged 18-25 years who reported past-year NMUPO. Self-reported reasons for most recent NMUPO were compared by educational status. The most commonly-endorsed reasons for past-year NMUPO was physical pain relief (47.6%), followed by feel good/get high (19.8%), relax/relieve tension (13.2%) and experiment/see what it feels like (6.8%). Reasons for NMUPO did not differ as a function educational status (p = 0.17). These findings suggest that efforts to prevent and address opioid misuse among young adults should focus on understanding and improving pain management in this vulnerable population.

Abstract
Objective To compare outcomes of early and delayed treatment with cidofovir for human adenovirus (HAdV) pneumonia. Methods A retrospective cohort study in Korean military hospitals was conducted between January 2012 and December 2018. Patients with potentially severe HAdV pneumonia with risk factors for respiratory failure were included and divided into early (within 7 days from symptom onset) and delayed (after 7 days from symptom onset) treatment groups. The primary outcome was respiratory failure development within 21 days after symptom onset. Results A total of 89 patients with potentially severe HAdV pneumonia were enrolled in the cohort; they included 62 early and 27 delayed treatment patients. All patients were males in their early 20s. Significantly fewer patients in the early treatment group progressed to respiratory failure (8/62, 12.9%), compared to the delayed group (18/27, 66.7%, p < 0.001). Early treatment was associated with a lower 21-day probability of respiratory failure by the Kaplan–Meier method (p < 0.001). On multivariate analysis, monocyte count, hypoxaemia, confusion, whole lung involvement, and early cidofovir treatment within 7 days from symptom onset were included, and monocyte count (HR 0.995, 95%CI 0.991–1.000, p 0.042), confusion (HR 4.964, 95%CI 1.189–20.721, p = 0.028), and early cidofovir treatment (HR 0.319, 95%CI 0.115–0.883, p = 0.028) were significantly associated with respiratory failure. Conclusions Early administration of cidofovir was associated with a lower hazard for respiratory failure development. It is suggested that cidofovir be administered within 7 days from symptom onset to prevent respiratory failure in patients with potentially severe HAdV pneumonia.

Abstract
BACKGROUND Fluoroquinolones are a popular alternative to trimethoprim-sulfamethoxazole for Stenotrophomonas maltophilia infections. OBJECTIVES To compare the effects of fluoroquinolones and trimethoprim-sulfamethoxazole on mortality of S. maltophilia infections. DATA SOURCES PubMed and EMBASE. STUDY ELIGIBILITY CRITERIA Clinical studies reporting mortality outcomes of S. maltophilia infections. PARTICIPANTS Patients with clinical infections caused by S. maltophilia. INTERVENTIONS Fluoroquinolone monotherapy in comparison with trimethoprim-sulfamethoxazole monotherapy. METHODS Systematic review with meta-analysis technique. RESULTS Seven retrospective cohort and seven case-control studies were included. Three cohort studies were designed to compare the two drugs, whereas others had other purposes. A total of 663 patients were identified, 332 of which were treated with trimethoprim-sulfamethoxazole (50.1%) and 331 with fluoroquinolones (49.9%). Three cohort studies were designed to compare the effect of the two drugs, whereas the others had other purposes. Levofloxacin was most frequently used among fluoroquinolones (187/331, 56.5%), followed by ciprofloxacin (114/331, 34.4%). The overall mortality rate was 29.6%. Using pooled ORs for the mortality of each study, fluoroquinolone treatment (OR 0.62, 95% CI 0.39-0.99) was associated with survival benefit over trimethoprim-sulfamethoxazole treatment, with low heterogeneity (I2 = 18%). Specific fluoroquinolones such as ciprofloxacin (OR 0.44, 95% CI 0.17-1.12) and levofloxacin (OR 0.78, 95% CI 0.48-1.26) did not show a significant difference in comparison with trimethoprim-sulfamethoxazole. In the sub-group analyses of adult and bacteraemic patients, significant differences in mortality were not observed between fluoroquinolones and trimethoprim-sulfamethoxazole. CONCLUSIONS Based on a meta-analysis of non-randomized studies, fluoroquinolones demonstrated comparable effects on mortality of S. maltophilia infection to trimethoprim-sulfamethoxazole, supporting the use of fluoroquinolones in clinical S. maltophilia infections. Although the pooled analysis of overall studies favoured fluoroquinolones over trimethoprim-sulfamethoxazole, the studies included were observational, and sub-group analyses of certain fluoroquinolone agents did not show statistical differences with trimethoprim-sulfamethoxazole. Randomized clinical studies are needed to address these issues.

Abstract
Posttraumatic stress disorder (PTSD) is a major health concern among veterans, specifically African American veterans, and is commonly comorbid with other negative mental health outcomes including substance use disorders (SUD) and symptoms of depression. The current study examined intolerance of uncertainty as a mediator of the relationship between PTSD and depression symptoms in a sample of African American veterans with a dual diagnosis of PTSD and SUD. Participants included 113 African American veterans who were in treatment for PTSD and SUD at a Veterans Affairs Medical Center. Five mediation analyses were conducted to examine the mediational effect of intolerance of uncertainty on the relationship between PTSD symptom clusters (i.e., total, hyperarousal, numbness, avoidance, and intrusion) and depression symptoms. Findings indicated that intolerance of uncertainty mediated the relationship between four of the five mediation models (i.e., total symptoms, hyperarousal, numbness, and intrusion). These results imply that for African American veterans, higher levels of certain PTSD symptoms were associated with higher levels of intolerance of uncertainty, which in turn were related to increased levels of depression symptoms.

Abstract
Pain and emotional distress are relevant risk factors as clinicians assess for aberrant opioid-associated behavior and provide adequate and responsible pain relief to patients who engage in behaviors that may be interpreted as drug seeking in nature. The present case illustrates how undertreated pain and treatment-related anxiety affected the opioid use of a young adult with cancer. Because these risk factors were identified during the initial consult, the treatment team was able to implement a multimodal and multidisciplinary treatment approach that provided the patient with better analgesia and coping skills for anxiety.

Abstract
Dysfunctional trauma-related cognitions are important in the emergence and maintenance of posttraumatic stress disorder (PTSD) and the modification of such cognitions is a proposed mechanism of trauma treatment. However, the authors are not aware of any research examining trauma-related cognitions as a treatment mechanism in a sample of individuals with comorbid PTSD and substance use disorder (SUD). Accordingly, the present study sought to address this gap in the literature and examined the relationship between trauma-related cognitions and treatment outcomes within a sample of seventy-two veterans diagnosed with PTSD and SUD. Veterans completed a 6-week day CPT-based treatment program that included cognitive processing therapy as a central component. Measures of trauma-related cognitions, PTSD symptoms, depressive symptoms, and trauma-cued substance craving were completed at pre- and post-treatment. As expected, trauma-related cognitions were associated with several PTSD-related variables prior to treatment. Furthermore, results of a within-subjects mediational analysis indicated that maladaptive trauma-related cognitions decreased during the treatment program and accounted for a significant portion of the variance in the reduction of PTSD and depressive symptoms at post-treatment. This study provides support for the position that attempts to modify dysfunctional trauma-related cognitions among veterans with co-occurring PTSD and SUD can lead to desirable treatment outcomes.

Abstract
Opioid use disorders (OUDs) are a growing problem in the United States. When OUDs co-occur with problematic drinking and posttraumatic stress disorder (PTSD), negative drug-related mental and physical health outcomes may be exacerbated. Thus, it is important to establish whether PTSD treatments with established efficacy for dually diagnosed individuals also demonstrate efficacy in individuals who engage in problematic drinking and concurrent opioid misuse. Adults who met DSM-IV-TR criteria for PTSD and alcohol dependence were recruited from a substance use treatment facility and were randomly assigned to receive either modified prolonged exposure (mPE) therapy for PTSD or a non-trauma-focused comparison treatment. Compared to adults in a non-OUD comparison group (n = 74), adults with OUD (n = 52) were younger, reported more cravings for alcohol, were more likely to use amphetamines and sedatives, were hospitalized more frequently for drug- and alcohol-related problems, and suffered from more severe PTSD symptomatology, depressive symptoms, and anxiety, standardized mean differences = 0.36-1.81. For participants with OUD, mPE was associated with large reductions in PTSD symptomatology, sleep disturbances, and symptoms of anxiety and depression, ds = 1.08-2.56. Moreover, participants with OUD reported decreases in alcohol cravings that were significantly greater than those reported by the non-OUD comparison group, F(1, 71.42) = 6.37, p = .014. Overall, our findings support the efficacy of mPE for PTSD among individuals who engage in problematic drinking and concurrent opioid misuse, despite severe baseline symptoms.

Abstract
Prescription opioid use has increased in recent decades. Although opioids provide effective pain control, their use may be associated with the risk of misuse. Opioid misuse (OM) is prevalent among adolescents and young adults (AYAs). Opioids are necessary to treat cancer-related pain; however, oncology patients are not immune to medication misuse. Research examining OM among AYAs with cancer is scarce. This article examines the risk factors described in the general adult and adolescent medication abuse literature and aims to provide recommendations for practice in the AYA oncology population. The following risk factors should be examined in AYA oncology patients to determine their relevance: age, sex, behavioral and academic problems, psychological conditions, and a history of illicit drug use/abuse. To maintain the delicate balance of providing adequate pain relief while protecting patients from the risk of OM, clinicians must consider potential risk factors, motivating factors, and individual behaviors. Placing these challenges in perspective, this review provides clinical considerations, recommendations, and intervention strategies for OM prevention in AYA oncology patients.

Abstract
BACKGROUND Although risk factors for medication-overuse headache have been identified within the general population, most studies have neglected clinical samples. The present study examined the relative and combined associations of these factors with medication-overuse headache in a sample of US adults seeking treatment for primary headache disorders. METHODS Treatment-seeking headache patients provided data on demographics, headache variables, psychiatric variables, use of headache medications, and use of other prescription medications and substances. A classification tree selection strategy was utilized within this cross-sectional study to differentiate between those with and without medication-overuse headache, and a final multivariable model assessed their combined utility. RESULTS Forty-three of 164 participants (26.2%) met diagnostic criteria for medication-overuse headache. Relative to non-medication-overuse headache participants, participants with medication-overuse headache reported greater headache-related disability (odds ratio = 1.09, 95% confidence interval = 1.01-1.18), escape and avoidance responses indicative of fear of pain (odds ratio = 1.07, 95% confidence interval = 1.00-1.15), and use of combination medications for headache (odds ratio = 3.10, 95% confidence interval = 1.51-6.36). The final multivariable model differentiated well between the 2 groups (area under the receiver operating characteristic curve = .78; 95% confidence interval = .71-.86). CONCLUSIONS Items that assess headache-related disability, use of combination medications, and fear of pain help identify patients who are currently overusing acute headache medications and may serve as indicators of treatment progress. Future studies should apply similar analytic approaches longitudinally to identify headache sufferers at risk for medication-overuse headache prior to headache progression.

Abstract
The efficacy of empirical non-carbapenem antibiotics for extended-spectrum beta-lactamase-producing Enterobacteriaceae bacteremia (ESBL-B) is still inconclusive. We conducted a multicenter retrospective cohort study to evaluate the efficacy of empirical non-carbapenem antibiotics for treating ESBL-B. Electronic medical records of individuals who were diagnosed with ESBL-B were reviewed between January 2010 and December 2014 at four university hospitals in Korea. Patients were classified into non-carbapenem and carbapenem groups according to the empirical antibiotic regimen. Patients treated with appropriate empirical antibiotics and who subsequently received carbapenems as definitive therapy were included in the analysis. The inverse probability of treatment weights, a statistical method that adjusts baseline statistics by giving weights based on propensity score, was used. During the study period, 232 adequately treated patients with ESBL-B were included in the analysis: 49 patients in the non-carbapenem group and 183 in the carbapenem group. The baseline characteristics and severity of infection were similar after propensity score weighting. The 30-day mortality rates for the two groups were not statistically significantly different (non-carbapenems 6.3% and carbapenems 11.4%; P = 0.42). In a multivariate analysis, empirical treatment with non-carbapenem antibiotics was not associated with 30-day all-cause mortality (HR 1.02, 95% CI 0.99-1.06, P = 0.14). In a subgroup analysis, empirical treatment with piperacillin-tazobactam was also not associated with 30-day all-cause mortality (HR 1.21, 95% CI 0.37-4.00, P = 0.75). Appropriate non-carbapenems were not inferior to carbapenems as initial empirical therapy for ESBL-B.

Abstract
To provide optimal cut-off values of anti-Middle East respiratory syndrome coronavirus (MERS-CoV) serologic tests, we evaluated performance of ELISA IgG, ELISA IgA, IFA IgM, and IFA IgG using 138 serum samples of 49 MERS-CoV-infected patients and 219 serum samples of 219 rRT-PCR-negative MERS-CoV-exposed healthcare personnel and patients. The performance analysis was conducted for two different purposes: (1) prediction of neutralization activity in MERS-CoV-infected patients, and (2) epidemiologic surveillance of MERS-CoV infections among MERS-CoV-exposed individuals. To evaluate performance according to serum collection time, we used ‘days post onset of illness (dpoi)’ and ‘days post exposure (dpex)’ assessing neutralization activity and infection diagnosis, respectively. Performance of serologic tests improved with delayed sampling time, being maximized after a seroconversion period. In predicting neutralization activity, ELISA IgG tests showed optimal performance using sera collected after 21 dpoi at cut-off values of OD ratio 0.4 (sensitivity 100% and specificity 100%), and ELISA IgA showed optimal performance using sera collected after 14 dpoi at cut-off value of OD ratio 0.2 (sensitivity 85.2% and specificity 100%). In diagnosis of MERS-CoV infection, ELISA IgG exhibited optimal performance using sera collected after 28 dpex, at a cut-off value of OD ratio 0.2 (sensitivity 97.3% and specificity 92.9%). These new breakpoints are markedly lower than previously suggested values (ELISA IgG OD ratio 1.1, sensitivity 34.8% and specificity 100% in the present data set), and the performance data help serologic tests to be practically used in the field of MERS management.

Abstract
Despite a significant increase of bloodstream infection caused by extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae in the community-setting, information regarding clinical outcomes of inappropriate empiric therapy (IAT) in patients with those infections is limited. A multicenter-retrospective cohort study was conducted in four hospitals. A total of 249 adults were identified to have community-onset bacteremia caused by ESBL-producing Escherichia coli and Klebsiella pneumoniae, and definitively treated with carbapenems. According to the appropriateness of empiric therapy, individuals were divided into an appropriate empiric therapy (AT) group (n = 106) and IAT group (n = 143). Patients who received AT showed more severe underlying conditions including underlying solid cancer, healthcare-association and intensive care unit (ICU) care, compared to the IAT group. Primary bacteremia was more commonly found in the AT group than in the IAT group, while urinary tract infection predominated more frequently in the IAT group than in the AT group. Multivariate analysis using propensity score analysis indicated that inappropriateness of empiric therapy was not an independent risk factor for 30-day death. ICU care, respiratory tract infection and underlying liver, renal and connective tissue diseases were significantly associated with mortality. In patients with bloodstream infections caused by ESBL-producing E. coli and K. pneumoniae in the community-setting, delay in appropriate therapy was not associated with an increased rate of death if the patients were definitively treated with carbapenems.

Abstract
Information on the incidence and prevalence of fungal infections is of critical value in public health policy. However, nationwide epidemiological data on fungal infections are scarce, due to a lack of surveillance and funding. The objective of this study was to estimate the disease burden of fungal infections in the Republic of Korea. An actuarial approach using a deterministic model was used for the estimation. Data on the number of populations at risk and the frequencies of fungal infections in those populations were obtained from national statistics reports and epidemiology papers. Approximately 1 million people were estimated to be affected by fungal infections every year. The burdens of candidemia (4.12 per 100,000), cryptococcal meningitis (0.09 per 100,000), and Pneumocystis pneumonia (0.51 per 100,000) in South Korea were estimated to be comparable to those in other countries. The prevalence of chronic pulmonary aspergillosis (22.4 per 100,000) was markedly high, probably due to the high burden of tuberculosis in Korea. The low burdens of allergic bronchopulmonary aspergillosis (56.9 per 100,000) and severe asthma with fungal sensitization (75.1 per 100,000) warrant further study. Oral candidiasis (539 per 100,000) was estimated to affect a much larger population than noted in previous studies. Our work provides valuable insight on the epidemiology of fungal infections; however, additional studies are needed.

Abstract
To evaluate effect of empirical combination of a β-lactam to vancomycin and vancomycin monotherapy in Staphylococcus aureus bacteremia (MSSA-B), we conducted a retrospective cohort study. Electronic medical records of individuals who were diagnosed with MSSA-B between January 2005 and February 2015 at a tertiary care center were reviewed. Patients were classified into three groups according to empirical antibiotic regimen (BL group, β-lactam; VAN group, vancomycin; BV group, combination of β-lactam and vancomycin), and 30-day all-cause mortality of each group was compared. During the study period, 561 patients with MSSA-B were identified. After exclusion of 198 patients (36 with poly-microbial infection, 114 expired within 2 days, and 48 already received parenteral antibiotics) and a matching process, 46 patients for each group were included. Baseline characteristics were similar except for severity and comorbidity scores. The 30-day mortality for all three groups were not significantly different (BL 4.3%, VAN 6.5%, BV 8.7%; P = 0.909). In a multivariate analysis, type of empirical antibiotic regimen was not statistically associated with 30-day all-cause mortality. In comparison with the VAN group, the BV group yielded a HR of 0.579 (95% CI = 0.086-3.890, P = 0.574). Pitt bacteremia score was the only significant factor for mortality. The empirical combination of a β-lactam to vancomycin was not associated with lower mortality in treating MSSA-B, compared to vancomycin monotherapy.

Abstract
PURPOSE Human papillomavirus (HPV) is a sexually transmitted infection and the cause of cervical and other cancers. Vaccination is available to protect against genital HPV and is recommended for individuals aged 9-26 years. This study aimed to estimate the prevalence of HPV vaccination among childhood cancer survivors and to identify factors associated with vaccine outcomes. METHODS Young adult females with (n = 114; M age = 21.18 years, SD = 2.48) and without (n = 98; M age = 20.65 years, SD = 2.29) a childhood cancer history completed surveys querying HPV vaccination initiation/completion, as well as sociodemographic, medical, and health belief factors. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95 % confidence intervals (CIs) for vaccine outcomes. RESULTS Among survivors, 38.6 % (44/114) and 26.3 % (30/114) initiated or completed vaccination compared to 44.9 % (44/98) and 28.6 % (28/98) among controls, respectively. In the combined survivor/control group, physician recommendation (OR = 11.24, 95 % CI 3.15-40.14) and familial HPV communication (OR = 7.28, 95 % CI 1.89-28.05) associated with vaccine initiation. Perceptions of vaccine benefit associated with vaccine completion (OR = 10.55, 95 % CI 1.59-69.92), whereas perceptions of HPV-related severity associated with non-completion (OR = 0.14, 95 % CI 0.03-0.71). CONCLUSION Despite their increased risk for HPV-related complication, a minority of childhood cancer survivors have initiated or completed HPV vaccination. Modifiable factors associated with vaccine outcomes were identified. IMPLICATIONS FOR CANCER SURVIVORS HPV vaccination is a useful tool for cancer prevention in survivorship, and interventions to increase vaccine uptake are warranted.

Abstract
BACKGROUND Despite advances in headache medicine, there remains little research on process-related variables that mediate relations between headache and outcomes, as well as limited dissemination of optimal statistical methodology for conducting mediation analyses. The present paper thus aims to promote and demonstrate a contemporary approach to mediation analysis as applied to headache. METHODS An overview of a contemporary path-analytic approach to mediation analysis is presented, with an empirical exemplar for illustrative purposes. In the exemplar, headache management self-efficacy (HMSE) was proposed as a mediator between headache severity and disability. The sample included 907 young adults (M age = 19.03 [SD = 2.26]; 70.8% female) with primary headache. Direct and indirect effects of headache severity on headache disability through HMSE were assessed using the espoused methods. RESULTS Pain severity was positively associated with headache disability (β = 2.91, 95% confidence interval [CI; 2.62, 3.19]) and negatively associated with HMSE (β = -3.50, 95% CI [-4.24, -2.76]); HMSE was negatively associated with headache disability (β = 0.07, 95% CI [-0.09, -0.04]). A positive indirect effect of pain severity on disability through HMSE was identified (point estimate = 0.24, 95% CI [0.14, 0.34]); thus, self-efficacy mediated the association between pain severity and disability. The proposed mediation model accounted for 38% of total variance in disability (P < .001). CONCLUSIONS There is a need for theory-driven and statistically rigorous mediation analyses within the headache literature. In one exemplar application, self-efficacy partially accounted for the disability resulting from headache. We advocate for increased attention to intervening variables in headache via dissemination of contemporary mediation analyses.

Abstract
Recent products of piperacillin/tazobactam (PTZ) from the original manufacturer, previously considered a major cause of galactomannan (GM) false-positivity, are reported not to be related to it. However, data regarding generic PTZ are limited and controversial. To evaluate the effect of generic PTZ on GM false-positivity in Korea, we performed a case-control study in adult patients with cancer. A case-control study was designed. Electronic medical records of cancer patients who were admitted and tested for serum GM between March and June 2014 at a tertiary care university hospital were reviewed. During the study period, a single generic PTZ (C manufacturer, Korea) was used. Patients who received PTZ within 24 h prior to serum GM testing were enrolled. Age- and GM test date-matched non-PTZ patients were selected as controls. A total of 110 patients received PTZ within 24 h prior to serum GM testing during the study period. The GM optical density index (ODI) of the PTZ group did not vary significantly from that of the control group (p = 0.251). The percentage of false-positive patients in the PTZ group was also similar to that of the control group (p = 0.538). There was no statistical relationship between GM ODI titer and time interval from PTZ administration (p = 0.095) or cumulative PTZ dose (p = 0.416). In a case-control study that evaluated 220 patients, a generic PTZ in Korea was not related to GM false-positivity.

Abstract
Scedosporium spp. is the most common mold infection in pneumonia resulting from near-drowning. Three fatal scedosporiosis cases developed after solid organ transplantation, probably transmitted from the nearly-drowned donor. One heart transplant recipient and two kidney transplant recipients developed fatal scedosporiosis following deceased donor transplantation from the same donor, a nearly-drowned victim of a suicide attempt. Genotypically, indistinguishable strains of Scedosporium auratiacum were recovered from the three recipients. Two liver transplant recipients from the same donor received prophylactic voriconazole without any subsequent signs of infection. To determine the safety of donation from nearly-drowned donors, a national traceback investigation was also performed of the causes of deaths in all transplant recipients who received organs from drowned donors between 2001 and 2013. Over 13 years, 2600 deceased donor transplants were performed in Korea. Among these 2600 deceased donor transplants, 27 (1%) victims of drowning donated their organs. From these 27 donors, 84 patients received organ transplants and 18 died, including the above three. We found no microbiologic evidence of invasive mold transmission from the nearly-drowned donors to the other 15 recipients. Although disseminated infection in the donor could not be demonstrated by culture, undiagnosed disseminated donor infection and transmission of Scedosporium spp. should be considered in near-drowning events.

Abstract
This study examined whether an intervention designed to reduce secondhand smoke exposure (SHSe) among children being treated for cancer had effects in the specific setting of a motor vehicle. The parents or guardians (n = 71) of children being treated for cancer were randomized to either a behavioral secondhand smoke (SHS) reduction program or a standard care control group. Parental reports of SHSe were collected over the course of 12 months. Younger children were exposed at baseline more than their older counterparts. The greatest initial declines in car exposure were observed among children ≤5 years old in the intervention group compared with same-aged peers in the control group. After the 3-month time point, the control group showed greater reductions in car exposure in comparison with the intervention group. Interventions that teach parents strategies to manage their smoking while driving in their personal vehicles may produce even greater reductions in child exposure and should be developed. Based on the age-specific results reported here, future studies should account for effects of child age and use setting-specific measures of SHS.

Abstract
AIM A constant reduction in the incidence of community-onset acute pyelonephritis (CO-APN) caused by Escherichia coli has been shown with a parallel increase incidence caused by other organisms. Therefore, we evaluated the risk factors and outcome of non-E. coli as uropathogens in patients with community-onset APN. METHODS As a part of a nationwide multicentre surveillance study conducted in Korea, a total of 416 patients with CO-APN were collected with their epidemiological, antibiotic treatment and outcome data. RESULTS The risk factors and outcomes of non-E. coli as uropathogens were evaluated in a total of 416 patients with culture-confirmed CO-APN. Non-E. coli caused 127 cases (30.5%) of CO-APN. CO-APN caused by non-E. coli resulted in higher inappropriate empirical therapy (38.6% vs. 20.1%, p < 0.001), longer hospital stay (12.6 days vs. 6.7 days, p = 0.005) and higher 30-day mortality (9.4% vs. 3.8% p = 0.020) compared with CO-APN caused by E. coli. Multivariate analyses showed that male gender (OR, 3.48; CI, 2.13-5.67; p < 0.001), underlying haematological disease (OR, 5.32; CI, 1.17-24.254; p = 0.031), underlying benign prostate hyperplasia (OR, 2.61; CI, 1.02-6.74; p = 0.046), chronic indwelling urethral catheter (OR, 6.34; CI, 1.26-31.84; p = 0.025) and admission history in the previous 6 months (OR, 2.12; CI, 1.23-3.58; p = 0.005) were predictors for CO-APN caused by a non-E. coli isolate. CONCLUSIONS Community-onset APN caused by non-E. coli represents a distinct subset of urinary tract infections with worse outcomes. The defined risk factors related with non-E. coli should be taken into consideration when empirical antibiotic therapy is prescribed in patients with community-onset APN.

Abstract
AIM Low serum albumin levels occur in a variety of disease states and are related to in-hospital mortality and length of stay. The purpose of this study was to evaluate the association of commonly measured biochemical markers in critically ill patients such as serum albumin or C-reactive protein (CRP) with the need for intensive respiratory or vasopressor support (IRVS) in patients with 2009 influenza A (H1N1). METHODS A total of 104 patients from an H1N1 registry database of 2436 patients were enrolled. Clinical characteristics and laboratory findings within 24 h of admission were reviewed to evaluate whether serum biochemical markers can be used as predictors of illness severity in adult patients with H1N1 based on the need for IRVS. RESULTS Twenty-four (23.1%) of the 104 patients enrolled in the study received IRVS during the study period. Independent predictors of the need IRVS were serum glucose level on admission (OR 1.02; 95% CI 1.00-1.04; p = 0.021) and serum albumin level on admission (OR 0.12; 95% CI 0.02-0.63; p = 0.013). The diagnostic sensitivity of albumin levels for predicting the need for IRVS in patients with confirmed H1N1 with a cut-off value of 2.7 g/dl was 79.17% (95% CI 57.8-92.9), the specificity was 85.71% (95% CI 75.9-92.6), the positive predictive value was 63.3% (95% CI 43.9-80.1) and the negative predictive value was 93.0% (95% CI 84.3-97.7). The area under the receiver operation characteristic curve was 0.860 (95% CI 0.773-0.923) for albumin, 0.808 (95% CI 0.713-0.882) for glucose and 0.734 (95% CI 0.633-0.821) for CRP. CONCLUSIONS Serum albumin levels and glucose levels on admission were predictors of the need IRVS in adult patients with H1N1. Based on these findings, the level of albumin at presentation may serve as a novel and simple early biomarker to identify patients at high risk for a complicated clinical course of disease.

Abstract
This study was performed to evaluate the clinical features of community-onset levofloxacin-nonsusceptible pneumococcal pneumonia and to identify risk factors for levofloxacin resistance. Using the database of a surveillance study of community-acquired pneumococcal infections in Asian countries, we conducted a nested case-control study to identify risk factors for levofloxacin-nonsusceptible S. pneumoniae in community-acquired pneumonia in adults. Of 981 patients with pneumococcal pneumonia, 46 (4.7 %) had levofloxacin-nonsusceptible S. pneumoniae, of whom 39 evaluable cases were included in the analysis. All cases were from Korea, Taiwan, and Hong Kong. Among patients with levofloxacin-susceptible S. pneumoniae, 490 controls were selected based on patient country. Of the 39 cases of levofloxacin-nonsusceptible pneumococcal pneumonia, 23 (59.0 %) were classified as healthcare-associated, while 164 (33.5 %) of the 490 controls of levofloxacin-susceptible S. pneumoniae (P = 0.001) were classified as healthcare-associated. Multivariate analysis showed that previous treatment with fluoroquinolones, cerebrovascular disease, and healthcare-associated infection were significantly associated with levofloxacin-nonsusceptible pneumococcal pneumonia (all P < 0.05). Levofloxacin-nonsusceptible pneumococci pose an important new public health threat in our region, and more information on the emergence and spread of these resistant strains will be necessary to prevent spread throughout the population.

Abstract
BACKGROUND Despite the frequent occurrence of acute kidney injury (AKI) associated with meticillin-resistant Staphylococcus aureus (MRSA) infection during treatment, the adverse impact of renal injury on clinical and economic outcomes has not been evaluated. AIM To study the clinical and economic burdens of MRSA bacteraemia and the impact of AKI occurring during treatment on outcomes. METHODS Medical records of patients hospitalized for MRSA bacteraemia between March 2010 and February 2011 in eight hospitals in Korea were reviewed retrospectively to evaluate the risk factors for AKI and mortality. Direct medical costs per patient of MRSA bacteraemia during treatment were estimated from the medical resources consumed. FINDINGS In all, 335 patients were identified to have MRSA bacteraemia. AKI occurred in 135 patients (40.3%) during first-line antibiotic therapy. Independent risk factors for AKI were male sex, underlying renal disease, intra-abdominal and central venous catheter infection, and increase in Pitt bacteraemia score. Seventy-seven (23.0%) patients died during the study period. Underlying solid tumour, high Pitt bacteraemia score, and occurrence of AKI were independent risk factors for mortality. The mean total medical cost per MRSA patient was estimated as South Korean Won 5,435,361 (US$4,906), and occurrence of AKI and ICU admission were identified as independent predictors of increased direct medical costs. Compared with patients who retained their baseline renal function, patients with AKI had a 45% increase in medical costs. CONCLUSIONS Patients who developed AKI showed significantly higher mortality rate and greater direct medical costs compared with patients who retained baseline renal function.

Abstract
OBJECTIVE This study was conducted to identify risk factors for mortality and to evaluate the impact of antimicrobial resistance on outcome in adult patients with invasive pneumococcal disease (IPD). METHODS A post hoc analysis of an observational cohort study on community-acquired pneumococcal infections was conducted and a total of 136 adult patients with IPD were analyzed in this study. RESULTS Pneumonia was the most common type of infection (n = 84, 61.8 %), followed by primary bacteremia (n = 15, 11.0 %) and meningitis (n = 15, 11.0 %). One hundred and three patients (75.7 %) had concomitant pneumococcal bacteremia. The overall 30-day mortality rate was 26.5 % (36/136), and factors associated with 30-day mortality were corticosteroid use, presentation with septic shock, and development of acute respiratory distress syndrome (ARDS) (all P < 0.05). While penicillin and erythromycin resistance were associated with a lower mortality, an association between levofloxacin resistance and increased mortality was found in the univariate analysis; however, statistical significance was not reached (P = 0.083). Multivariable analysis showed that presentation with septic shock, corticosteroid use, development of ARDS, and levofloxacin resistance were independent factors associated with 30-day mortality. Of the five patients with IPD caused by levofloxacin-resistant Streptococcus pneumoniae, three (60 %) died within 30 days of diagnosis. CONCLUSION Levofloxacin resistance was associated with increased mortality, along with septic shock, prior use of corticosteroids, and development of ARDS, in adult patients with IPD. Our data suggest that the emergence of levofloxacin resistance among invasive pneumococcal isolates is now becoming a challenge for clinicians managing community-acquired bacterial infections.

Abstract
BACKGROUND Preemptive therapy is used to prevent cytomegalovirus (CMV) disease in transplant recipients. The CMV antigenemia assay, which has been commonly used as a predictive marker for preemptive therapy, requires intensive labor and immediate processing. We compared the cutoff value of plasma CMV polymerase chain reaction (PCR) with CMV antigenemia in kidney transplant recipients. METHODS We compared two diagnostic methods for CMV infection in kidney transplant recipients: quantitative PCR (qPCR) versus antigenemia. We evaluated the optimal cutoff value of plasma CMV qPCR by using receiver-operating characteristic curves for specific antigenemia values. All kidney transplant recipients from January 2004 to January 2005 were enrolled and followed with CMV antigenemia and plasma CMV qPCR. RESULTS The analyses were performed on 899 samples collected from 111 patients in the early posttransplant period, matching 84.1% of patients for the results of CMV antigenemia and plasma CMV qPCR. For patients with symptomatic CMV infection and disease, who showed ≥25 positive cells in the antigenemia assay, the cutoff value for qPCR was 17.8 copies/μL with a sensitivity of 97.1%, a specificity of 89.1%, and a positive predictive value of 26.6%. CONCLUSIONS Diagnostic assays for CMV such as CMV antigenemia and quantitative plasma PCR, showed similar diagnostic values. They are the methods of choice for the diagnosis and monitoring of active CMV infection after kidney transplantation. However, because of the relatively low positive predictive value of qPCR, this test may lead to unnecessary preemptive treatment in kidney transplant recipients.

Abstract
A retrospective, observational cohort study was conducted to describe the incidence, clinical and microbiological findings and to evaluate risk factors for treatment failure associated with prosthetic joint infections (PJIs). We retrospectively reviewed the medical records of all patients undergoing total knee or total hip prosthesis implantation in our institution between 1994 and 2008. Our institution is a 1950-bed tertiary care university hospital and referral centre. A total of 93 patients with PJIs was identified although only 68 patients had undergone prosthesis implantation at our hospital. The overall infection rate was 0.63%. The most common organisms isolated were Gram positive (76.5%), including meticillin-resistant staphylococci. Two-stage arthroplasty was performed in 48 (51.6%) patients, and debridement and retention of the prosthesis in 34 (36.5%) patients. When 43 patients followed up for more than two years after treatment were included in treatment outcome analysis, the overall treatment failure rate was 41.8% (18/43). Staphylococcus aureus infection was the only clinical variable associated with treatment failure (odds ratio: 11.9; 95% confidence interval: 1.07e133.9; P = 0.044), after adjustment for the other variables. In conclusion, S. aureus was the most common pathogen isolated in patients with PJI, and an independent risk factor for treatment failure in patients with PJI.

Abstract
This study was conducted to evaluate the epidemiology and clinical features of bloodstream infections caused by extended-spectrum beta-lactamase-producing E. coli (ESBL-EC) in community-onset bacteremia. Of 929 episodes of community-onset E. coli bacteremia, 4.1% (38/929) had bacteremia with ESBL producers. Of these, 63.2% (24/38) were further classified as healthcare-associated infections. Although most patients had risk factors for infection due to ESBL producers, three patients with urinary tract infection, four patients with cholangitis, and one patient with a liver abscess had no identified predisposing risk factors. The 30-day mortality was 21.1% (8/38). ESBL-EC is a significant cause of bloodstream infection, even in patients with community-onset infection.

Abstract
BACKGROUND Results of prospective studies on the effect of prophylactic antibiotics before percutaneous endoscopic gastrostomy are conflicting. Factors for increased risk of peristomal wound infection have not been clearly identified. AIM To evaluate the incidence of complications of percutaneous endoscopic gastrostomy and to determine the predictors of wound infection. PATIENTS AND METHODS Percutaneous endoscopic gastrostomy was performed on 134 patients in different disease groups between January 1996 and June 2000. Medical records were carefully reviewed for demographic data, indications for percutaneous endoscopic gastrostomy, use of prophylactic antibiotics, complications and comorbid conditions predisposing to wound infection. RESULTS Of 134 patients, 22 (16.4%) developed complications after percutaneous endoscopic gastrostomy Wound infection, the most common complication, occurred in 19 patients (14.2%) and Pseudomonas aeruginosa was the most frequently isolated microorganism. In univariate analysis, non-malignant disease and diabetes mellitus were significantly associated with peristomal wound infection after percutaneous endoscopic gastrostomy. In multivariate analysis, only diabetes mellitus was an independent risk factor for the development of peristomal wound infection after percutaneous endoscopic gastrostomy (p = 0.035) CONCLUSIONS Patients with diabetes mellitus have a higher risk of peristomal wound infection after percutaneous endoscopic gastrostomy.

Abstract
Although Pseudomonas aeruginosa is not generally considered as a cause of antibiotic-associated diarrhea, several cases of diarrhea caused by P. aeruginosa have been reported. We experienced seven cases of nosocomial diarrhea presumably caused by P. aeruginosa, which was the predominant organism isolated from stool cultures. Clostridium difficile toxin was also positive in one patient. No other potential or recognized enteropathogens were identified from stools. All patients had underlying diseases and had been receiving antibiotics before the diarrheal onset. All of the seven P. aeruginosa isolates were resistant to previously given antibiotics. Diarrhea stopped three days after withdrawal of probable offending antibiotics without specific treatment in two patients. The other five patients having continuous diarrhea despite withdrawal of probable offending antibiotics, were successfully treated with antipseudomonal agents. The median duration of diarrhea after the initiation of treatment was 6.3 days. These data suggest that P. aeruginosa can be a potential cause of antibiotic-associated diarrhea. Further investigations are warranted to evaluate the possible etiologic role of P. aeruginosa in antibiotic-associated diarrhea.

Abstract
To investigate the nasal carriage of antibiotic-resistant pneumococci by children, anterior nasal swabs were done for 4963 children <5 years old in 11 countries in Asia and the Middle East. In total, 1105 pneumococci isolates (carriage rate, 22.3%) were collected, 35.8% of which were found to be nonsusceptible to penicillin. Prevalence of penicillin nonsusceptibility was highest in Taiwan (91.3%), followed by Korea (85.8%), Sri Lanka (76.5%), and Vietnam (70.4%). Penicillin resistance was related to residence in urban areas, enrollment in day care, and a history of otitis media. The most common serogroups were 6 (21.5%), 23 (16.5%), and 19 (15.7%). The most common clone, as assessed by pulsed-field gel electrophoresis, was identical to the Spanish 23F clone and to strains of invasive isolates from adult patients. Data in this study documented the high rate of penicillin or multidrug resistance among isolates of pneumococci carried nasally in children in Asia and the Middle East and showed that this is due to the spread of a few predominant clones in the region.

Abstract
This study was performed to evaluate the effect of granulocyte-colony stimulating factor on neutrophil functions in diabetic patients with active foot infections in vitro. Twelve diabetic patients with foot infections and 12 normal volunteers were enrolled. Neutrophils from peripheral blood were incubated with granulocyte colony-stimulating factor (G-CSF, 50 ng/mL) for 20 min. Superoxide production of neutrophils was measured by the reduction of ferricytochrome C. Neutrophil phagocytosis was assayed using Staphylococcus aureus and the weighted phagocytic index was calculated. Superoxide production of neutrophils in diabetic patients with foot infections was 7.7 (unit: nmol/2 x 10(5) cells/60 min), which was significantly lower than that in controls (12.0) (p<0.05). G-CSF increased neutrophil superoxide production to 12.1 in diabetic patients with foot infections and to 19.8 in controls (p<0.05 for each). Weighted phagocytic index in diabetic patients with foot infections was 0.77, which was not significantly different from that of the controls (0.69). Weighted phagocytic index was increased significantly by G-CSF to 0.88 in diabetic patients with foot infections and to 0.79 in controls (p<0.05 for each). In conclusion, G-CSF significantly enhanced neutrophil functions in diabetic patients with foot infections in vitro.

Abstract
The purpose of this study was to evaluate the ability of pulse inversion harmonic imaging with or without microbubble ultrasonographic contrast agent in depicting renal parenchymal changes in acute pyelonephritis. The study population included 30 patients with acute pyelonephritis and 10 healthy volunteers. Pulse inversion harmonic imaging with or without contrast agent was compared with conventional ultrasonography and tissue harmonic imaging in terms of detection and conspicuity of renal abnormalities. The detection and conspicuity of renal parenchymal abnormalities in acute pyelonephritis on tissue harmonic imaging, pulse inversion harmonic imaging, and contrast-enhanced pulse inversion harmonic imaging were significantly better than those on conventional ultrasonography. In 2 of 10 healthy volunteers all 4 techniques yielded false-positive diagnoses of parenchymal abnormalities. In conclusion, tissue harmonic imaging and pulse inversion harmonic imaging are sensitive techniques for depicting renal parenchymal lesions in acute pyelonephritis. Despite relatively lower specificities and negative predictive values, these techniques are thought to be useful for the depiction of subtle parenchymal changes in acute pyelonephritis.

Abstract
INTRODUCTION This study was conducted to determine the usefulness of routine pharyngeal cultures in pediatric sexual assault victims. METHODS A retrospective chart review was conducted to examine incidence data. The study was conducted in a 656-bed tertiary care hospital with 60,000 ED visits and approximately 350 pediatric sexual assault examinations annually. Records of all pediatric sexual assault examinations completed between 12:01 AM January 1, 1994, and 12:01 AM January 1, 1997, were retrospectively reviewed for inclusion. Subjects were included if they were younger than 15 years and had a nonacute examination for a suspected sexual assault. The final sample included 370 females and 81 males (total n=451 children). Oral and anal cultures were obtained on all patients. In addition, female patients had vaginal cultures and male patients had penile cultures performed. Culture specimens were sent for detection of chlamydia and gonococcus organisms. RESULTS Of the 451 sets of cultures examined, there were 6 patients with one or more positive culture results. The 6 patients yielded a total of 10 positive culture results: 1 anal only, 1 vaginal only, and 4 both anal and vaginal. This was a positive culture rate of 1.3% overall. The positive culture result rates by site were oral 0%, vaginal 1.6%, anal 1.1%, and penile 0%. The ages of patients with positive culture results ranged from 2 to 13 years; all of those with positive culture results were female. DISCUSSION The incidence of positive oral culture results in this sample was zero. This finding supports a more limited approach to standard sexually transmitted disease screening in pediatric sexual assault victims. The elimination of routine oral cultures in pediatric victims without alleged oral contact decreases the examination time, decreases the number of invasive procedures associated with the examination, and decreases the cost of the examination without negatively affecting patient care.

Abstract
Pulsed-field gel electrophoresis, ribotyping, and fingerprinting analysis of 22 invasive isolates of multidrug-resistant (MDR) pneumococci from Korea showed that 59 to 82% were genetically related. DNA sequencing of the PBP 2B gene showed relatively uniform alterations in nucleotides (5.4 to 7.8%) and amino acids (3.0 to 4. 3%), while Asn-276-->Lys, Arg-285-->Cys and Ser-305-->Phe substitutions were unique to Korean MDR strains, suggesting the spread of a few epidemic clones of resistant pneumococci within Korea.
