RESUMEN
This study aimed to determine the level of interleukin (IL)-8 in diagnosing of invasive pulmonary aspergillosis (IPA). We conducted this study with 50 controls and 25 IPA patients with haematological malignancies. Demographic data, haematological diagnoses, chemotherapy regimen, galactomannan level, fungal culture, and computed tomography findings of the patients were evaluated prospectively. IL-8 levels were studied with the ELISA method. The mean age of patients in the case group was 60.84 ± 15.38 years, while that of the controls was 58.38 ± 16.64 years. Of the patients, 2/25 were classified as having 'proven', 13/25 as 'probable', and 10/25 as 'possible' invasive aspergillosis (IA). Serum IL-8 levels were found to be significantly higher in the case group compared to the controls. There was a negative correlation between serum IL-8 levels and neutrophil counts and a positive correlation with the duration of neutropenia. A significant cutoff value for serum IL-8 parameter in detecting IPA disease was obtained as ≥274 ng/l; sensitivity was 72%; specificity was 64%; PPV was 50%; and NPV was 82%. In the subgroup analysis, there was no significant difference in serum IL-8 levels between the case group and the patients in the neutropenic control group, while a significant difference was found in with the patients in the non-neutropenic control group. Serum IL-8 levels in neutropenic patients who develop IPA are not adequate in terms of both the diagnosis of the disease and predicting mortality. New, easily applicable methods with high sensitivity and specificity in diagnosing IPA are still needed.
Although a significant cutoff value for serum interleukin (IL)-8 was found in the diagnosis of IPA, there was no statistical difference in serum IL-8 when subgroup analysis was performed with neutropenic control patients. Therefore, serum IL-8 is not a successful marker in diagnosing neutropenic patients with IPA.

Objective: Reuse of medical devices poses risks concerning technical issues and patient safety. In this study, we aimed to examine the structural changes in catheters that occur due to the reuse with the aid of electron microscopy. Materials and Methods: The effects of hydrogen peroxide (HP) and ethylene oxide (EO) sterilization on four percutaneous transluminal coronary angioplasty (PTCA) catheters and control PTCA catheters were examined by scanning electron microscope (SEM). Each catheter sample was divided into four parts during the SEM examination, and a total of 20 pieces were examined. Catheters were reprocessed through every regular sterilization step and used solely for the study, not in patients. Statistical evaluations of histological scoring made on images obtained from scanning electron microscopic images were made using the GraphPad Prism 8 program. Results: Electron microscopical examination showed that HP sterilization caused more robust and deeper lines compared to EO. These distortions increased directly with the increase in the reprocessing cycle. In EO, no significant damage was detected within five cycles in contrast to HP; however, the harmful effects of EO were seen over five cycles. Unprocessed samples had no damage. Outer and inner deterioration was significantly higher in the EO>5 group and HP>5 group than in the control group. However, the bacterial contamination score in the EO>5 group was higher than the control group. Conclusion: Our findings showed that HP and EO sterilizations caused some deterioration in the inner and outer surfaces of PTCA catheter samples. We recommend reprocessing using EO, the least damaging method, when necessary, and paying attention not to exceed five cycles when necessary.
RESUMEN
BACKGROUND: The systemic immune-inflammation index (SII), based on white blood cell, neutrophil, and platelet counts, is a proposed marker of systemic inflammation and immune activation. This study aimed to explore the relationship between SII and complete atrioventricular block (CAVB) development in STEMI patients undergoing primary PCI. METHODS: We retrospectively analyzed data from 883 patients who underwent primary PCI for STEMI between January 2009 and December 2017. Patients were categorized into two groups based on CAVB development. SII levels were calculated from blood samples taken on admission. RESULTS: Of the included patients, 48 (5.03%) developed CAVB. SII was higher in patients with CAVB compared to those without CAVB (1370 [1050-1779]x109/L vs. 771 [427-1462] x109/L, p < 0.001). Multivariate analysis showed a significant positive correlation between SII and the risk of CAVB development (OR:1.0003, 95%CI:1.0001-1.0005, P = 0.044). The cut-off value for the SII in the estimation of CAVB was 1117.7 × 109/L (area under the ROC curve [AUC]: 0.714, 95% CI = 0.657-0.770 with a sensitivity of 70.8% and specificity of 65.6%, p < 0.001). CONCLUSION: This study showed a significant link between high SII levels and CAVB development in STEMI patients undergoing PCI. Our findings suggest that SII may be a valuable, routinely available, and inexpensive marker for identifying patients at increased risk of CAVB.

Considering the increasing use of the transcatheter aortic valve implantation (TAVI) procedure, the relationship of contrast-induced nephropathy (CIN) with post-TAVI mortality has become important. The Mehran score was developed to detect the risk of CIN development after cardiac intervention. We aimed to compare the role of the modified Mehran score, which can be calculated pre-procedure, in predicting CIN development and compare it with the original Mehran score. We retrospectively collected data from TAVI procedures at our institution between December 2016 and June 2021; of 171 patients, 44 (25.7%) had CIN. We found no association between contrast media volume and CIN (387 ± 120 vs 418 ± 139 mL, P = .303). High and very high modified Mehran score and preoperative C-reactive protein (CRP) level were independent risk factors for CIN development after TAVI procedure. The area under curve (AUC) was .686 with 95% CI: .591-.780 and P < .001, and also, with a cut-off point of >7.5 points, there was 79.5% sensitivity and 63.0% specificity; otherwise, with a cut-off point of >9.5 points, there was 54.5% sensitivity and 71.7% specificity, for the modified Mehran score. The modified Mehran score comes into prominence compared with the original Mehran score since it can be calculated pre-procedure.

BACKGROUND: The number and proportion of elderly patients living with chronic hepatitis C are expected to increase in the coming years. We aimed to compare the real-world efficacy and safety of direct-acting antiviral treatment in elderly and younger Turkish adults infected with chronic hepatitis C. METHODS: In this multicenter prospective study, 2629 eligible chronic hepatitis C patients treated with direct-acting antivirals between April 2017 and December 2019 from 37 Turkish referral centers were divided into 2 age groups: elderly (≥65 years) and younger adults (<65 years) and their safety was compared between 2 groups in evaluable population. Then, by matching the 2 age groups for demographics and pretreatment risk factors for a non-sustained virological response, a total of 1516 patients (758 in each group) and 1244 patients (622 in each group) from the modified evaluable population and per-protocol population were included in the efficacy analysis and the efficacy was compared between age groups. RESULTS: The sustained virological response in the chronic hepatitis C patients was not affected by the age and the presence of cirrhosis both in the modified evaluable population and per-protocol population (P = .879, P = .508 for modified evaluable population and P = .058, P = .788 for per-protocol population, respectively). The results of the per-protocol analysis revealed that male gender, patients who had a prior history of hepatocellular carcinoma, patients infected with non-genotype 1 hepatitis C virus, and patients treated with sofosbuvir+ribavirin had a significantly lower sustained virological response 12 rates (P < .001, P = .047, P = .013, and P = .025, respectively). CONCLUSION: Direct-acting antivirals can be safely used to treat Turkish elderly chronic hepatitis C patients with similar favorable efficacy and safety as that in younger adults.

BACKGROUND: Since its first introduction, the spectrum and frequency of use of transcatheter aortic valve implantation (TAVI) have increased throughout the world. Therefore, it is crucial to determine which patients are at high mortality risk with TAVI. The Intermountain Risk Score (IMRS) is a score calculated from laboratory parameters. This study aimed to determine the long-term mortality of TAVI patients using the IMRS and to compare it with traditional scoring systems. METHODS: The study included a total of 133 patients undergoing TAVI at our hospital from 2010 to 2019. Demographic data, co-morbid diseases, echocardiographic and laboratory parameters were collected retrospectively. The performance of IMRS was assessed as compared to the mortality determined in the overall patient population. RESULTS: During the follow-up, 54.9% of patients (60 patients) (Group 1) survived; the mortality in Group 2 (60 patients) was 45.1%. The survival period had a mean of 1433 (±124) days. The mean IMRS was 1.67 (0.7) in Group 1 and 2.33 (0.72) in Group 2 (P <0.001). In multivariable analyses, only high risk of IMRS (hazard ratio [HR], 3.430; 95% confidence interval [CI], 1.537-7.653; P = 0.003) and EuroSCORE II (HR, 1.141; 95% CI, 1.011-1.288; P = 0.03) independently predicted long-term mortality. CONCLUSIONS: From the evaluation of all laboratory and echocardiography parameters, long-term mortality (>30 days) following the TAVI procedure can be said to be higher in patients with a high IMRS. The data from this study can be considered of value in demonstrating the clinical significance of IMRS calculation before the TAVI procedure.

AIMS: Hepatitis B virus (HBV) infection is a worldwide distributing viral disease. Hepatitis caused by HBV reactivation may progress to chronic illness and associated with increased risk of hepatic failure and hepatocellular cancer. Rituximab (RTX) is an immunosuppressive agent, is particularly used in the treatment of non-Hodgkin's Lymphoma. Patients have significant risk for HBV reactivation following chemotherapy with a RTX-containing regimen. This study aimed to determine the HBV screening manner and reactivation rates in patients with haematological neoplasm following chemotherapy including Rituximab. METHODS: This is a single-centered retrospective cohort study. A total of 331 adults with haematological disorders who received chemotherapy regimen including RTX between years of 2006 and 2016 were enrolled. Patients who experienced reactivation were evaluated. RESULTS: Only 130 of 331 patients were screened appropriately for HBV infection for 10-year period. We found 18 patients were Hepatitis B surface antigen (HBsAg) (+) and 16 (88.8%) of them received antiviral prophylaxis. Among screened patients, 27 were HBsAg (-)/AntiHBc (+) and only 10 (37%) of them received HBV prophylaxis. In total, nine patients experienced reactivation, six were from screened and three were from unscreened group. CONCLUSION: Incomplete screening and inappropriate prophylaxis may result in HBV reactivation in patients under RTX-based chemotherapy and related complications such as death.

As the COVID-19 pandemic continues, countries still have to struggle with their endemic diseases such as Crimean-Congo hemorrhagic fever (CCHF). Severity grading score (SGS) is a practical approach and may shed light on the course of the CCHF, whose pathogenesis is not clearly understood, and have no effective treatments. It is aimed to assess the association between SGS and acute phase reactants (APR). Laboratory-confirmed patients were categorized by severity scores, and the relationship between APR and SGS was evaluated. A significant correlation between SGS and C-reactive protein (CRP) was found (p < 0.001). High SGS was associated with mortality and high CRP levels were used to predict the mortality at the beginning of the hospital admission. To predict the outcome of the disease and for appropriate patient management, SGS and APR can be used simultaneously.

BACKGROUND: Crimean Congo Hemorrhagic Fever (CCHF) is a life threatening acute viral infection that presents significant risk of nosocomial transmission to healthcare workers. AIM: Evaluation of CCHF infection prevention and control (IP&C) practices in healthcare facilities that routinely manage CCHF cases in Eurasia. METHODS: A cross-sectional CCHF IP&C survey was designed and distributed to CCHF centers in 10 endemic Eurasian countries in 2016. RESULTS: Twenty-three responses were received from centers in Turkey, Pakistan, Russia, Georgia, Kosovo, Bulgaria, Oman, Iran, India and Kazakhstan. All units had dedicated isolation rooms for CCHF, with cohorting of confirmed cases in 15/23 centers and cohorting of suspect and confirmed cases in 9/23 centers. There was adequate personal protective equipment (PPE) in 22/23 facilities, with 21/23 facilities reporting routine use of PPE for CCHF patients. Adequate staffing levels to provide care reported in 14/23 locations. All centers reported having a high risk CCHFV nosocomial exposure in last five years, with 5 centers reporting more than 5 exposures. Education was provided annually in most centers (13/23), with additional training requested in PPE use (11/23), PPE donning/doffing (12/23), environmental disinfection (12/23) and waste management (14/23). CONCLUSIONS: Staff and patient safety must be improved and healthcare associated CCHF exposure and transmission eliminated. Improvements are recommended in isolation capacity in healthcare facilities, use of PPE and maintenance of adequate staffing levels. We recommend further audit of IP&C practice at individual units in endemic areas, as part of national quality assurance programs.

INTRODUCTION: Colistin is associated with dose-dependent nephrotoxicity. N-acetylcycteine (NAC) may reduce the risk of concomitant acute kidney injury (AKI) due to its antioxidant properties. We report a retrospective cohort study evaluating the role of N-acetylcysteine (NAC) in the development of colistin (COL) associated nephrotoxicity. METHODOLOGY: A single centre retrospective cohort study was conducted in a university hospital between January 2014 and June 2015. Nephrotoxicity was defined and staged per the RIFLE (Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease) criteria. We evaluated the association between NAC use and COL-related nephrotoxicity by comparing the incidence of nephrotoxicity in patients receiving colistin with or without adjunctive NAC. RESULTS: Forty-six patients received intravenous (IV) COL and 46 patients received IV NAC+COL. The cumulative COL doses did not differ between the two groups (p = 0.802). The initial creatinine value doubled in 29 (63%) patients undergoing NAC+COL therapy and in 27 (58.7%) patients in the COL group (p = 0.669). The median doubling time of baseline creatinine was 6 and 7 days in the NAC+COL and COL groups, respectively. The mean hospital stay, potentially nephrotoxic agent use, and mortality rates were statistically higher for the patients receiving NAC+COL (p < 0.005). CONCLUSIONS: The present study was not able to reveal any beneficial effect of NAC for patients undergoing COL therapy. The NAC+COL group had a higher baseline risk for development of AKI. However, the incidence of AKI was comparable between the groups. The results of the study would not solely exhibit the protective effect of adjunctive NAC therapy.
RESUMEN
Carbapenem-resistant Klebsiella pneumoniae (CRKP) has been known as a nosocomial pathogen, both for the last 10 years in Turkey and for 20 years worldwide. Due to limited treatment options and high mortality rates, despite improvements in the field of medicine at the present time, CRKP is still a big threat for public health. This study was carried out between the dates of January 2010 and September 2014. Patients ≥18 who were hospitalized for at least 72 h and who also had CRKP growth were included in the study as a case group. In the same period patients, who were hospitalized in the same ward and did not have CRKP growth were selected as the control group. It was determined that no glycopeptides and steroids use nor tracheostomy as protective factors would be employed in terms of non-development of CRKP. Mechanical ventilation, tracheostomy, urinary catheter presence, central venous catheterization, nasogastric tube placement, advanced age, acute renal insufficiency, total parenteral nutrition, carbapenem, glycopeptide, and piperacillin tazobactam were all detected as risk factors in terms of CRKP infection development. As a result, rational usage of antibiotics for preventing infections developing with CRKP should be targeted.

Crimean-Congo hemorrhagic fever (CCHF) is endemic in Turkey, with peak incidence of hospital admissions in the summer months. The aim of this pilot study was to evaluate the role of the severity grading score (SGS) in predicting length of hospital stay, laboratory usage, need for blood products, and hence total costs of patients. Thirty-five patients admitted to one specialist center in Turkey in 2013 and 2014 with PCR-proven CCHF. The mean (SD) age was 55 (±14) and 63% of the patients were male, with 8 (22.9%) mortality. Patients were classified by SGS into three groups with mortality as follows: low risk (0/19); intermediate (6/14); and high (2/2). The direct hospital cost of these admissions was at least $41 740 with median (range) of $1210 ($97-$13 054) per patient. There was a significant difference between low-risk and combined (intermediate-high) risk groups as 635 (97-1500) and 2264.5 (154-13 054), respectively (p = 0.012). In conclusion, a clinical grading score can be used to predict illness severity and to predict associated health care costs.

Mobile communication devices help accelerate in-hospital flow of medical information, information sharing and querying, and contribute to communications in the event of emergencies through their application and access to wireless media technology. Healthcare-associated infections remain a leading and high-cost problem of global health systems despite improvements in modern therapies. The objective of this article was to review different studies on the relationship between mobile phones (MPs) and bacterial cross-contamination and report common findings. Thirty-nine studies published between 2005 and 2013 were reviewed. Of these, 19 (48.7%) identified coagulase-negative staphylococci (CoNS), and 26 (66.7%) identified Staphylococcus aureus; frequency of growth varied. The use of MPs by healthcare workers increases the risk of repetitive cyclic contamination between the hands and face (e.g., nose, ears, and lips), and differences in personal hygiene and behaviors can further contribute to the risks. MPs are rarely cleaned after handling. They may transmit microorganisms, including multiple resistant strains, after contact with patients, and can be a source of bacterial cross-contamination. To prevent bacterial contamination of MPs, hand-washing guidelines must be followed and technical standards for prevention strategies should be developed.

The aim of this study was to investigate the in-vitro antimicrobial activity of usage and normal concentrations of electrolyzed water in hospital. In our study, the effects of different concentrations of electrolyzed water named Envirolyte® (Industries International Ltd., Estonia) on two gram positive, four gram negative standard strains and clinical isolates of four gram negative, two gram positive, one spore-forming bacillus and Myroides spp strains that lead to hospital infections were researched. The effects of different concentrations and different contact times of Envirolyte® electrolyzed water on cited strains were researched through method of qualitative suspension tests. Petri dishes fo bacteria have been incubated at 37°C 48 hours. Bactericidal disinfectant was interpreted to be effective at the end of the period due to the lack of growth. Solutions to which disinfectant were not added were prepared with an eye to control reproduction and controlcultures were made by using neutralizing agents. 1/1, 1/2, and 1/10 concentrations of Envirolyte® electrolyzed water were found to be effective on the bacteria that lead to hospital infections used during all test times. As a conclusion, based upon the results we acquired, it was observed that Envirolyte® electrolyzed water of 100% concentration would be convenient to be used for disinfection when diluted to a usage concentration of 1/10.
RESUMEN
The incidence of fungal infections has increased in recent years. Antifungal resistance is a major problem with increasing frequency due to the widespread use of antifungal agents in infections. Identification of the Candida species and susceptibility patterns with the appropriate tests for resistance and selection of the empirical agents used for treatment are important. The aim of the study was to evaluate the changes of the epidemiology of Candida species and minimum inhibitory concentrations (MIC) of the antifungal agents, isolated in Mycology Laboratory of Ondokuz Mayis University Faculty of Medicine, between 1 January 2009 to 1 July 2012. The study was performed retrospectively based on records in the mycology unit and checked comparatively with the automation system in the hospital. The recurrent reproductions of the same patient were excluded. For the identification of Candida species API®ID 32C (bioMerieux, France) system was used. Information on the isolated material, patient's age, gender and the inpatients' clinics were recorded. The susceptibility of Candida species isolated from blood cultures were studied with Etest (bioMerieux, France) method. A total of 1238 isolates were included in the study. The most common species isolated from clinical samples was C.albicans with a rate of 51.1% (n= 632), followed by C.tropicalis with a rate of 15.8% (n= 195). Among the pediatric intensive care unit (ICU) patients C.parapsilosis 42% (n= 17) was the most common isolate and the second most common isolate was C.albicans 32% (n= 13). However, in the adult ICU the most common isolate was C.albicans 34% (n= 13) and the second was C.parapsilosis 31% (n= 12). When the distribution of Candida species were analyzed from the records of last four years, the frequency rate of C.albicans and non-albicans species was found as 51.1% (n= 632) and %48.9 (n= 606), respectively. Based on these data, a comparison was made between the years and no difference between the two groups in terms of the distribution of fungi within the specified time (x²: 3.2, df: 1, p: 0.073) was determined. Of the Candida species isolated from blood cultures, seven isolates (2.2%) were resistant to fluconazole in the study period. The differences of MIC levels in fluconazole were detected between the years 2010-2012 and 2011-2012. The geometric mean of the MICs in 2012 increased significantly compared to 2010 and 2011 (p< 0.01). There was no resistance to amphotericin B except for intrinsically resistant Candida lusitaniae. There were no significant differences among amphotericin MIC values between years (p> 0.05). According to the sensitivity results, fluconazole is still seen as an option that can be used for the first choice. Although it remains as the first antifungal choice, antifungal susceptibility testing of the identified fungi will help the clinician for the plan and continuation of the treatment.
RESUMEN
BACKGROUND: Surgical site infections (SSIs) are a threat to patient safety; however, there were no available data on SSI rates stratified by surgical procedure (SP) in Turkey. METHODS: Between January 2005 and December 2011, a cohort prospective surveillance study on SSIs was conducted by the International Nosocomial Infection Control Consortium (INICC) in 20 hospitals in 16 Turkish cities. Data from hospitalized patients were registered using the Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN) methods and definitions for SSIs. Surgical procedures (SPs) were classified into 22 types according to International Classification of Diseases, Ninth Revision criteria. RESULTS: We recorded 1879 SSIs, associated with 41,563 SPs (4.3%; 95% confidence interval, 4.3-4.7). Among the results, the SSI rate per type of SP compared with rates reported by the INICC and CDC NHSN were 11.9% for ventricular shunt (vs 12.9% vs 5.6%); 5.3% for craniotomy (vs 4.4% vs 2.6%); 4.9% for coronary bypass with chest and donor incision (vs 4.5 vs 2.9); 3.5% for hip prosthesis (vs 2.6% vs 1.3%), and 3.0% for cesarean section (vs 0.7% vs 1.8%). CONCLUSIONS: In most of the 22 types of SP analyzed, our SSI rates were higher than the CDC NHSN rates and similar to the INICC rates. This study advances the knowledge of SSI epidemiology in Turkey, allowing the implementation of targeted interventions.

AIMS: To evaluate the effectiveness of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Hand Hygiene Approach in Turkey and analyse predictors of poor hand hygiene compliance. DESIGN: An observational, prospective, interventional, before-and-after study was conducted from August 2003 to August 2011 in 12 intensive care units (ICU) of 12 hospitals in 11 cities. The study was divided into a baseline and a follow-up period and included random 30-minute observations for hand hygiene compliance in ICU. The hand hygiene approach included administrative support, supplies availability, education and training, reminders in the workplace, process surveillance, and performance feedback. RESULTS: We observed 21,145 opportunities for hand hygiene. Overall hand hygiene compliance increased from 28.8% to 91% (95% CI 87.6-93.0, p 0.0001). Multivariate and univariate analyses showed that several variables were significantly associated with poor hand hygiene compliance: males vs. females (39% vs. 48%; 95% CI 0.79-0.84, p 0.0001), ancillary staff vs. physicians (35% vs. 46%, 95% CI 0.73-0.78, p 0.0001), and adult vs. pediatric ICUs (42% vs. 74%, 95% CI 0.54-0.60, p 0.0001). CONCLUSIONS: Adherence to hand hygiene was significantly increased with the INICC Hand Hygiene Approach. Specific programmes should be directed to improve hand hygiene in variables found to be predictors of poor hand hygiene compliance.
RESUMEN
INTRODUCTION: Although pegylated interferons (pegIFNs) alpha-2a and alpha-2b have been used in chronic hepatitis B (CHB) treatment for many years, there are few studies concerning predictors of sustained virologic response (SVR) to pegIFN therapy. In this study, we aimed to investigate the predictors of response to pegIFN treatment in cases with HBeAg-negative CHB infection. METHODOLOGY: Seventeen tertiary care hospitals in Turkey were included in this study. Data from consecutively treated HBeAg-negative CHB patients, who received either pegIFN alpha-2a or alpha-2b, were collected retrospectively. SVR is defined as an HBV DNA concentration of less than 2,000 IU/mL six months after the completion of therapy RESULTS: SVR was achieved in 40 (25%) of the 160 HBeAg-negative CHB patients. Viral loads in patients with SVR were lower compared to those with no SVR, beginning in the third month of treatment (p < 0.05). The number of cases with a decline of 1 log10 IU/mL in viral load after the first month of treatment and with a serum HBV DNA level under 2,000 IU/mL after the third month of treatment was higher in cases with SVR (p < 0.05). The number of patients who had undetectable HBV DNA levels at week 48 among responders was significantly greater than among post-treatment virological relapsers (p < 0.05). CONCLUSIONS: Detection of a 1 log10 decline in serum HBV DNA level at the first month of treatment and a serum HBV DNA level < 2000 IU/mL at the third month of therapy may be predictors of SVR.
