The escalating conflicts in the Middle East have been associated with the rapid collapse of the existing healthcare systems in affected countries. As millions of refugees flee their countries, they become vulnerable and exposed to communicable diseases that easily grow into epidemic crises. Here, we describe infectious disease epidemics that have been associated with conflicts in the Middle East, including cholera, poliomyelitis, measles, cutaneous leishmaniasis, and diphtheria, that call for appropriate preventive measures. Local ongoing wars and failing healthcare systems have resulted in regional and global health threats that warrant international medical interventions.

IPA should be considered in patients with solid tumours, particularly those with underlying lung disease. Key messages Invasive pulmonary aspergillosis should be considered in patients with solid tumours, particularly those with underlying lung disease, lung cancer and those who received chest radiotherapy. Most of the patients with invasive pulmonary aspergillosis and solid tumours presented with nonspecific symptoms and signs as well as nonspecific CT findings. Unlike patients with hematologic malignancies, fever and hemoptysis were not predominant symptoms and the classical halo sign and the air-crescent sign were not described. Independent risk factors for 12-week mortality included receiving steroids within 30 days of diagnosis and chest radiotherapy. In multivariate analysis, a positive fungal stain was associated with lower odds of a successful response to antifungal therapy, whereas voriconazole treatment was associated with higher odds.

BackgroundCatheter-related septic thrombosis is suspected in patients with persistent central line–associated bloodstream infection (CLABSI) after 72 hours of appropriate antimicrobial therapy. The clinical diagnosis and management of this entity can be challenging as limited data are available. We retrospectively studied the clinical characteristics of patients with Staphylococcus aureus catheter-related septic thrombosis and the outcomes related to different management strategies.MethodsThis retrospective study included patients with CLABSI due to S. aureus who had concomitant radiographic evidence of catheter site thrombosis treated at our institution between the years 2005 and 2016. We collected data pertaining to patients’ medical history, clinical presentation, management, and outcome within 3 months of bacteremia onset.ResultsA total of 128 patients were included. We found no significant difference in overall outcome between patients who had deep vs superficial thrombosis. Patients with superficial thrombosis were found to have a higher rate of pulmonary complications (25% vs 6%; P = .01) compared with those with deep thrombosis. Patients who received less than 28 days of intravascular antibiotic therapy had higher all-cause mortality (31 vs 5%; P = .001). A multivariate logistic regression analysis identified 2 predictors of treatment failure: ICU admission during their illness (odds ratio [OR], 2.74; 95% confidence interval [CI], 1.08–6.99; P = .034) and not receiving anticoagulation therapy (OR, 0.24; 95% CI, 0.11–0.54; P < .001).ConclusionsOur findings suggest that the presence of S. aureus CLABSI in the setting of catheter-related thrombosis may warrant prolonged intravascular antimicrobial therapy and administration of anticoagulation therapy in critically ill cancer patients.

Candida auris poses emerging risks for causing severe central lineassociated bloodstream infections. We tested in vitro the ability of antifungal lock solutions to rapidly eradicate C. auris biofilms. Liposomal amphotericin B, amphotericin B deoxycholate, fluconazole, voriconazole, micafungin, caspofungin, and anidulafungin failed to completely eradicate all 10 tested C. auris biofilms. Conversely, nitroglycerin-citrate-ethanol (NiCE) catheter lock solution completely eradicated all replicates for all of C. auris biofilms tested.

BackgroundEarly antifungal therapy for invasive aspergillosis (IA) has been associated with improved outcome. Traditionally, of empiric antifungal therapy has been used for clinically suspected IA. We compared outcomes of patients with hematologic malignancy and IA who were treated with voriconazole using the diagnostic driven DDA (DDA-Vori) that includes galactomannan testing vs. empiric therapy with a non-voriconazole-containing regimen (EMP-non-Vori) or empiric therapy with voriconazole (EMP-Vori).MethodsWe retrospectively reviewed the medical records of 342 hematologic malignancy patients diagnosed with proven, or probable IA between July 1993 and February 2016 at our medical center who received at least 7 days of DDA-Vori, EMP-Vori, or EMP-non-Vori. Outcome assessment included response to therapy (clinical and radiographic), all-cause mortality, and IA-attributable mortality.ResultsBy multivariate analysis, factors predictive of a favorable response included localized/sinus IA vs. disseminated/pulmonary IA (p <  0.0001), not receiving white blood cell transfusion (p <  0.01), and DDA-Vori vs. EMP-non-Vori (p < 0.0001). In contrast, predictors of mortality within 6 weeks of initiating IA therapy included disseminated/pulmonary infection vs. localized/sinus IA (p < 0.01), not undergoing stem cell transplantation within 1 year before IA (p = 0.01), and EMP-non-Vori vs. DDA-Vori (p < 0.001).ConclusionsDDA-Vori was associated with better outcome (response and survival) compared with EMP-non-Vori and with equivalent outcome to EMP-Vori in hematologic malignancy patients. These outcomes associated with the implementation of DDA could lead to a reduction in the unnecessary costs and adverse events associated with the widespread use of empiric therapy.

Ten years after the Centers for Disease Control and Prevention recommended universal HIV screening, rates remain low. Internal medicine residents are the front-line medical providers for large groups of patients. We evaluated the knowledge of internal medicine residents about HIV testing guidelines and examined adherence to universal HIV testing in an outpatient setting. A cross-sectional survey of internal medicine residents at four residency programs in Chicago was conducted from January to March 2016. Aggregate data on HIV screening were collected from 35 federally qualified community health centers in the Chicago area after inclusion of an HIV testing best practice alert in patients' electronic medical records. Of the 192 residents surveyed, 130 (68%) completed the survey. Only 58% were aware of universal HIV screening and 49% were aware that Illinois law allows for an opt-out HIV testing strategy. Most of the residents (64%) ordered no more than 10 HIV tests in 6 months. The most frequently reported barriers to HIV testing were deferral because of urgent care issues, lack of time, and the perception that patients were uncomfortable discussing HIV testing. From July 2015 to February 2016, the average HIV testing adherence rate in the 35 health centers was 18.2%. More effort is needed to change HIV testing practices among internal medicine residents so that they will adopt this approach in their future clinical practice. Improving knowledge about HIV testing and addressing other HIV testing barriers are essential for such a successful change.

Conclusion: S. epidermidis bacteraemia was caused by a genetically heterogeneous group of organisms, but only a limited number of STsdparticularly multidrug-resistant ST2 and ST5 strainsdcaused complicated infections.
