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.

Molecular diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) by real-time reverse transcription polymerase chain reaction (RT-PCR) in respiratory specimens is considered the gold standard method. This method is highly sensitive and specific but it has some limitations such as being expensive and requiring special laboratory equipment and skilled personnel. RapidFor™ Antigen Rapid Test Kit is a commercially available Ag-RDT which is produced in Turkey and designed to detect the nucleocapsid antigen of SARS-CoV-2 in nasopharyngeal swab samples. The aim of this study was to evaluate the performance of this novel SARS-CoV-2 antigen detection considering the RT-PCR method as the gold standard. Four hundred forty-four nasopharyngeal swab samples which were collected from the patients who met clinical criteria of COVID-19 from ten centers in Turkey between September 2020 and February 2021 were included in the study. All the nasopharyngeal swab samples were tested for SARS-CoV-2 RNA using commercial RT-PCR kits (Bioeksen and A1 Lifesciences, Istanbul, Turkey) according to the manufacturer's instructions. Viral loads were assessed according to the cycle threshold (Ct) values. RapidFor™ SARS-CoV-2 antigen test (Vitrosens Biotechnology, Istanbul, Turkey) was used to investigate the presence of SARS-CoV-2 antigen in all samples following the manufacturer's instructions. Out of 444 nasopharyngeal swab samples tested, 346 (77.9%) were positive and 98 (22.1%) were negative for SARS-CoV-2 RNA by RTPCR. Overall sensitivity of the RapidFor™. Antigen Rapid Test Kit was 80.3% whereas specificity was found to be 87.8%. Positivity rate of rapid antigen test in samples with Ct values over 25 and below 30 was 82.7%, while it increased to 95.7% in samples 20 ≤ Ct < 25 and reached 100% in samples with Ct values below 20. RapidFor™ SARS-CoV-2 Ag test might be a good choice in the screening of symptomatic and asymptomatic patients and their contacts for taking isolation measures early, with advantages over RT-PCR as being rapid, easy and being applicable in every laboratory and even at point of care.

OBJECTIVE: Newborns are vulnerable to all types of infections due to their developing immune system. To compensate for their immune immaturity, newborns rely on the passive transfer of antibodies through the placenta and own mother's breast milk (BM). In the present study, we investigated whether vaccination against SARS-CoV-2 leads to the presence of antibodies in BM. Furthermore, we compared the levels of SARS-CoV-2-specific anti-spike (anti-S) IgG antibodies in the BM of mothers who were vaccinated against Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or had coronavirus disease 2019 (COVID-19) infection naturally or were vaccinated after natural infection. STUDY DESIGN: This was a prospective cohort study conducted in the Ondokuz Mayis University Faculty of Medicine. Forty-six mothers who had at least two doses of the BNT162b2 messenger RNA-based vaccine and/or had a history of symptomatic COVID-19 infection were included in the study. BM samples were analyzed by the Abbott Architect SARS-CoV-2 IgG II Quant kit following the manufacturer's instructions. RESULTS: Forty-six mothers with an average age of 29.7 ± 5.7 years participated the study: 18 (39.1%) had COVID-19 infection + BTN162b2 vaccine, 17 (37.0%) had BTN162b2 vaccine, and 11 (23.9%) had natural infection. The highest SARS-CoV-2-specific anti-S IgG antibody titers in BM were found in mothers who were vaccinated following the infection (anti-SARS-CoV-2 IgG: 32.48 ± 57.1 arbitrary units AU/mL). However, no significant difference in anti-SARS-CoV-2 antibody levels was observed between the three groups (p = 0.641). No antibody was detected in 15.2% of BM samples. CONCLUSION: Both vaccination and natural COVID-19 infection during pregnancy leads to the passive transfer of specific anti-SARS-CoV-2 IgG antibodies to BM. These results are important to overcome vaccine hesitancy and increase vaccination levels in expectant mothers. KEY POINTS: · We investigated the levels of SARS-CoV-2 antibodies in BM after natural infection and vaccination.. · Anti-SARS-CoV-2 IgG antibodies were detected in 39 (84.8%) BM samples.. · The highest titers in BM were found in mothers who were vaccinated following natural infection..
RESUMEN
Invasive fungal infections (IFI) continue to be an important cause of morbidity and mortality in patients with hematological malignancies. Candida and Aspergillus species constitute most of the IFI in these patients.. It has been reported that most of the invasive aspergillosis epidemics are related to the construction works in the hospital. In this study, we aimed to investigate the frequency of IFI in the old and the new hospital building after relocation in patients with hematological malignancies. Of 8042 patients who were hospitalized in the Department of Hematology, Ondokuz Mayis University Faculty of Medicine between January 2015 and September 2019, 412 patients who were initiated antifungal therapy were included in the study. The patients in the hematology clinic, which were moved to the new oncology hospital building in January 2018, were grouped as prior and after relocation, and their demographical data, hematological diagnosis, chemotherapy regimens, mortality, IFI, focus of infection, presence of central venous catheter, antifungal prophylaxis and treatment, galactomannan level, fungal culture and computed tomography (CT) findings were evaluated retrospectively. It was determined that 55% of the patients were male and the median age was 58 (range:18-93). The rate of IFI development was 5.12% (n= 412) and the rate of invasive mold infection was 1.2% (n= 145). The most common hematological disease for which antifungal treatment initiated was acute myeloid leukemia (AML) with a rate of 50% (n= 206/412). Of patients, 73% received induction chemotherapy (42%, first induction, 31% reinduction), 13.4% received consolidation therapy. Invasive mold infection was diagnosed as 40% possible, 59% probable, 1% proven. While patients had similar characteristics such as age, gender, hematological disease, chemotherapy regimens and antifungal prophylaxis prior and after transportation, the rate of development of invasive mold infection was 2.1%, 2.06 / 1000 patient days, before transportation, 1.37% (p= 0.009), 1.15/1000 patient days (p<0.001) after transportation, and it was statistically significantly lower after transportation. The median value of galactomannan antigen was detected as 0.17 (0.02-5.9). Blood cultures revealed 10.3% fungal growth and the most common growth was Candida albicans with 54.8% and Mucor spp. as mold with 3.2%. Large-scale construction works such as renovation, extension and demolition works in old hospital buildings are a permanent condition in different units. Clinicians should be aware of that infections due to opportunistic fungi can be seen in immunosuppressive patients close to such construction sites, and even cause epidemics. It should be kept in mind that these infections, which can progress with serious morbidity and mortality are difficult to treat but can be prevented by infection control measures.

We aimed to develop a scoring system for predicting in-hospital mortality of community-acquired (CA) sepsis patients. This was a prospective, observational multicenter study performed to analyze CA sepsis among adult patients through ID-IRI (Infectious Diseases International Research Initiative) at 32 centers in 10 countries between December 1, 2015, and May 15, 2016. After baseline evaluation, we used univariate analysis at the second and logistic regression analysis at the third phase. In this prospective observational study, data of 373 cases with CA sepsis or septic shock were submitted from 32 referral centers in 10 countries. The median age was 68 (51-77) years, and 174 (46,6%) of the patients were females. The median hospitalization time of the patients was 15 (10-21) days. Overall mortality rate due to CA sepsis was 17.7% (n = 66). The possible predictors which have strong correlation and the variables that cause collinearity are acute oliguria, altered consciousness, persistent hypotension, fever, serum creatinine, age, and serum total protein. CAS (%) is a new scoring system and works in accordance with the parameters in third International Consensus Definitions for Sepsis and Septic Shock (Sepsis-3). The system has yielded successful results in terms of predicting mortality in CA sepsis patients.

BACKGROUND: The aim of this study was to assess health-related quality of life (HRQOL) among chronic hepatitis B (CHB) patients in Turkey and to study related factors. METHODS: This multicenter study was carried out between January 01 and April 15, 2015 in Turkey in 57 centers. Adults were enrolled and studied in three groups. Group 1: Inactive HBsAg carriers, Group 2: CHB patients receiving antiviral therapy, Group 3: CHB patients who were neither receiving antiviral therapy nor were inactive HBsAg carriers. Study data was collected by face-to-face interviews using a standardized questionnaire, Short Form-36 (SF-36) and Hepatitis B Quality of Life (HBQOL). Values equivalent to p < 0.05 in analyses were accepted as statistically significant. RESULTS: Four thousand two hundred fifty-seven patients with CHB were included in the study. Two thousand five hundred fifty-nine (60.1 %) of the patients were males. Groups 1, 2 and 3, consisted of 1529 (35.9 %), 1721 (40.4 %) and 1007 (23.7 %) patients, respectively. The highest value of HRQOL was found in inactive HBsAg carriers. We found that total HBQOL score increased when antiviral treatment was used. However, HRQOL of CHB patients varied according to their socio-demographic properties. Regarding total HBQOL score, a higher significant level of HRQOL was determined in inactive HBV patients when matched controls with the associated factors were provided. CONCLUSIONS: The HRQOL score of CHB patients was higher than expected and it can be worsen when the disease becomes active. Use of an antiviral therapy can contribute to increasing HRQOL of patients.

OBJECTIVE: To evaluate the presence of uropathogens in the periurethral skin and the effect of phimosis on bacterial colonisation. METHODS: The observational cohort study was conducted in Samsun Research and Training Hospital, Samsun, Turkey from June to December, 2014, and comprised patients undergoing circumcision. Before circumcision, all children were examined in the operating room and the presence of phimosis was recorded. All patients had circumcision performed by the same surgical team under general anaesthesia. Before the procedure, samples were taken from preputial skin of all patients by swab before cleansing with polyvidone-iodine. The samples were inoculated on 5% sheep blood agar and eosin-methylene blue agar. RESULTS: The median age of the 117 children was 5 years (range: 1-12). Of the total, 19(16.2%) children had complete phimosis, and 72(61.5%) had partial phimosis. In all,91(77.7%) children had phimosis and 26(22.3%) had no phimosis. Of the 91 patients with different degrees of phimosis, 52(57.1%) had clinically significant uropathogenic bacterial colonisation >100,000 colony-forming units per millilitre [cfu/ml]). Of the 26 patients without phimosis, 13(50%) had clinically significant colonisation. Thus, there was no effect of the presence of phimosis on bacteria colonisation (p=0.655). CONCLUSIONS: Important uropathogens colonise the preputium in uncircumcised male children. There was no effect of phimosis on colonisation.

OBJECTIVE: To determine the bacterial colonisation after double-J stent use and the risk factors for bacteriuria linked to the stent. MATERIALS AND METHODS: A total of 102 patients (61 men and 41 women, mean age 47.5 ± 14.16) were examined. The stents were removed under aseptic conditions, and a urine culture was obtained before the removal of the stents. After the stents were removed, the upper, central and lower sections were separated, and washing water was sent through the stent. RESULTS: Bacterial colonisation was found in 29.4% (30 of 102) of the stents. The most frequently observed microorganisms were determined as staphylococcus, coagulase negative (8 of 30) and E. coli (5 of 30). The washing fluid used to clean the interior of the catheter produced pathogens in 8 patients (7.8%), and these pathogens were observed to be the same microorganisms that colonised the outside of the stent. There was no statistical difference between the patients with colonisation and those without in terms of age, gender, duration of stenting and reason for stent insertion. CONCLUSIONS: Though stent colonisation does not always entail symptomatic urinary tract infections, as shown in our study, the pathogens in the urine culture are the same as those colonising the stent, confirming the reality that colonisation is the main factor in these events. Additionally, according to our study, significant colonisation may be found in the first 3 weeks, contrary to the literature, causing us to consider that urinary tract infections may develop even in the early period.

Hemophagocytic lymphohistiocytosis (HLH) is a rare syndrome of excessive inflammation and tissue destruction due to abnormal immune activation and inflammation. HLH can occur primarily due to genetic etiology, or secondarily associated with malignancies, autoimmmune diseases or infections. There are a number of reports that revealed the relationship of hemophagocytosis with brucellosis. In this report, we described a brucellosis-related HLH case. A 73-year-old male who work as farmer was admitted to our hospital with the complaints of fever continuing for 10 days, loss of appetite and back pain. Physical examination revealed right upper quadrant tenderness and hepatomegaly. Since the patient exhibited five of the diagnostic criteria for HLH (fever, hepatosplenomegaly, bicytopenia, hypertriglyceridemia and high ferritin level), he was diagnosed as secondary HLH. PCR, microscopic agglutination and indirect fluorescent antibody tests gave negative results for the diagnosis of Crimean-Congo hemorrhagic fever, leptospirosis and Q fever, respectively. On the other hand, Rose Bengal test for brucellosis was positive, while standard tube agglutination test (STA) was negative. The patient's serum yielded a very high positive (1/1280) result when Coombs' test was performed in terms of the possibility of blocking antibodies or prozone phenomenon. Additionally, B.melitensis was isolated from his blood culture on the sixth day. The patient was treated with doxycycline and rifampicin, and on the 10th day of antibiotic therapy the patient was discharged and recommended to complete his treatment up to 6 weeks. In conclusion, in patients with secondary HLH symptoms especially in the endemic areas, brucellosis should be considered as a predisposing infection.

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
The coronavirus disease 2019 (COVID-19) pandemic, which has caused a major global health crisis, primarily targets the upper and lower respiratory tract. But infected individuals may experience different clinical symptoms, ranging from asymptomatic to critical. The vitamin D receptor (VDR) and Toll-like receptor 2 (TLR2) polymorphisms play a role in the immune response. This study aimed to evaluate the effect of VDR Bsml (rs1544410) and TLR2 23bp indel variants on the clinical status of Turkish patients with COVID-19 disease. A total of 312 people, including 106 intensive care unit (ICU) patients, 103 symptomatic hospitalized patients, and 103 healthy controls, were included in the study. The VDR BsmI and TLR2 23bp indel were genotyped using polymerase chain reaction and/or restriction fragment length fraction methods. The VDR BsmI b/b genotype and b allele were higher in symptomatic patients compared to the healthy control group (p = 0.035). The VDR BsmI B/B and B/b genotype distribution did not differ between ICU patients and both symptomatic patients and controls (p > 0.05). We found that B/B:B/b+b/b and B/B+B/b:b/b were significantly different in symptomatic patients compared to controls (p = 0.033 and p = 0.041, respectively). The VDR BsmI b/b genotype distribution was found to be lower in deceased patients than in living patients (p = 0.023). There was no significant difference between the groups in terms of TLR2 23bp indel genotype and allele distribution (p > 0.05). Our study results suggest that the VDR BsmI b allele may have a role in COVID-19 patients with symptomatic findings. These data need to be repeated in different ethnic and larger sample groups.
RESUMEN
Objective: Fournier's gangrene (FG) is a rare necrotizing fasciitis affecting genital and perianal areas. This study aimed to provide data on predicting factors, mortality rates, and factors affecting mortality in comparison of survivors and non-survivors in patients with FG. Materials and Methods: This study included a retrospective analysis of patients diagnosed with FG between 2008 and 2018. Results: A total of 97 patients with FG were included in this study. Of the patients, 72 (74%) were male. The mean age was 56.03±13.92 years, and the median was 57 (21-90). The mortality rate was 21.6%. The most frequently isolated microorganism from tissue and blood cultures was Escherichia coli (43%-42%). The median Fournier's Gangrene Severity Index (FGSI) and Uludag FGSI (UFGSI) scores were 4 (0-20) and 5 (1-22), respectively. In the univariate model, mortality risk increases 7.18 times (p=0.001) in patients with two or more comorbidities, 1.31 times as the FGSI score increases (p<0.001), 1.28 times as the UFGSI score increases (p<0.001). When the cut-off value was set as 8 for the FGSI score, the sensitivity was 71.43%, and the specificity was 73.68%. The sensitivity was 73.43%, and the specificity was 75% when the cut-off value was set as 6 for the UFGSI score. In the univariate model, the mortality risk of those with hypotension was 6.07 times higher (p=0.003); as the platelet count increased, mortality risk decreased (odds ratio [OR]=0.99; p=0.02). The mortality risk of those hospitalized in the intensive care unit (ICU) was 16.5 times higher than those followed in the ward (p<0.001). In the multivariate model, this ratio was 6.49. Conclusion: We concluded that FGSI and UFGSI scores could be used to predict mortality. Management of FG requires a multidisciplinary approach. Empiric treatment should include carbapenems and be de-escalated once getting the culture results. Authors from different centers should report their experiences to help reveal the ideal treatment and evaluate the consequences.
RESUMEN
PURPOSE: The purpose of this study is to compare patient-reported voice handicap and auditory-perceptual measures of voice between healthy individuals and COVID-19 patients, as well as to investigate the effect of clinical factors on voice quality. METHODS: COVID-19 patients (n = 138) and 90 healthy controls were included in the study. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) was used to grade voice samples based on overall severity, roughness, breathiness, strain, pitch, and loudness. The Voice Handicap Index-10 was completed by all participants (VHI-10). Physical (pVHI), emotional (eVHI) and functional (fVHI) subscores were calculated. Clinical data were collected (disease stage, CT grade, neutrophil/lymphocyte ratio, CRP, and symptoms). RESULTS: A statistically significant difference between patient and control groups in VHI-10 and CAPE-V scores was detected (p < 0.001). Except eVHI, total score and all subscale scores were higher in patients with COVID-19 as the pVHI was the most affected (η2 = 0.324) subscale. All scores of CAPE-V were significantly worse in patients with COVID-19 as highest impact of COVID-19 was on breathiness (η2 = 0.518). Pre-existing pulmonary comorbidity, dyspnoea and N/L was significantly associated with the VHI-10 overall score (ßpc = 4.27, ßdyspnoea = 5.69 and ßnl = 0.25). The overall severity of CAPE-V was significantly dependent on dyspnoea and pulmonary comorbidity (ßdyspnoea = 11.25, ßpc = 10.12). VHI ≥4 and CAPE-V overall severity ≥11 were good indicators of COVID-19 related dysphonia. CONCLUSIONS: COVID-19 causes patient-reported voice handicap and deteriorates auditory-perceptual measures of voice. COVID-19 related voice impairment was mainly associated with the decreased respiratory capacity.

INTRODUCTION: Brucellosis is often confused with other diseases or accompanies the conditions it imitates. It causes treatment delays, failure, relapse, and complications. This study aimed to investigate bacteremia and complication predictors in Brucellosis patients. Early detection may help reduce relapse rates, length of hospital stay, and surgical intervention rates by providing appropriate treatment. METHODOLOGY: We examined 220 adult patients diagnosed with Brucellosis in our tertiary care hospital in the Black Sea Region between January 01, 2010, and January 01, 2022. Patients with and without bacteremia and complications were compared regarding demographic characteristics, clinical features, and laboratory parameters. RESULTS: The mean age was 46.4 ± 15.8 years (18-96 years), and 61% were male. Low back pain and absence of muscle pain were independent risk factors for predicting bacteremia (p = 0.049, p = 0.043, respectively). Weakness /fatigue, weight loss, and 1/320 Standard Tube Agglutination Test (STAT) or Brucella Coombs Gel Test (BCGT) titers were independent risk factors that reduced the risk of complications; in contrast, low back pain and splenomegaly were independent risk factors for development of complications. (p = 0.025, p = 0.007, p = 0.008, p = 0.003, p = 0.021 respectively). Thrombocytopenia was related to complications. When the platelet cut-off value was taken as 160,000/µL in predicting complications, the sensitivity was 31.30%, and the specificity was 97.73% (p = 0.011). CONCLUSIONS: The risk of clinical progression and complications could be predicted with symptoms and signs such as myalgia, low back pain, weakness/fatigue, weight loss, splenomegaly, and easily accessible laboratory parameters such as serum STAT/BCGT titer and platelet level.

Pseudomonas aeruginosa which is a common cause of nosocomial infections, usually leads to treatment difficulties due to multi-drug resistance. PER-1 type extended-spectrum beta-lactamase (ESBL) producing bacteria are shown to be common in Turkey. Since limited number of antibiotics such as antipseudomonal penicillins, cephalosporins, aminoglycosides, fluoroquinolones and carbapenems are available for the treatment of P.aeruginosa infections, it is essential to monitor and eventually control the spread of antibiotic resistance genes. The aims of this study were to investigate the presence of PER-1 type ESBLs in nosocomial P.aeruginosa isolates and to evaluate their resistance to some commonly used antibiotics. A total of 110 P.aeruginosa strains isolated from clinical samples [40 urine, 26 exudate, 20 blood, 24 others (sputum, tracheal aspirate, tissue biopsy, cerebrospinal fluid, pleural fluid, conjunctiva)] of the inpatients who were proven to have nosocomial infections in Ondokuz Mayis University Faculty of Medicine Hospital between May 2002-June 2003 were included in the study. Identification of the isolates was performed by ATB system ID 32 GN (bio-Merieux, France). Antibiotic susceptibilities were detected by standard disk diffusion method and PER-1 type ESBL was searched by polymerase chain reaction using PER-1 and PER- 2 primers. PER-1 positivity was detected in 62 of 110 (56.4%) P.aeruginosa isolates and 51 of 65 (78.5%) ceftazidime-resistant strains. The highest susceptibility rate was detected for ciprofloxacin (76.4%), while the lowest susceptibility rate was for ticarcillin-clavulanic acid (22.7%). Rates of resistance to beta-lactam agents (excluding piperacillin/tazobactam), amikacin and gentamicin were statistically significantly higher for PER-1 positive strains than PER-1 negative ones. Resistance rates to ceftazidime, cefepime, aztreonam, piperacillin and ticarcillin-clavulanic acid in PER-1 positive isolates versus negative ones were as 82.3% vs. 29.2% (p< 0.01), 75.8% vs. 25% (p< 0.01), 83.9% vs. 30.4% (p< 0.01), 73.8% vs. 52.2% (p< 0.05), 85.5% vs. 66.7% (p< 0.05), respectively. Considering resistance rates to piperacillin-tazobactam and ciprofloxacin, PER-1 positive isolates versus negatives were 35.5% vs. 31.3%, and 19.4% vs. 29.2%, respectively, revealing no statistical significance (p> 0.05). As a result, PER-1 type ESBL frequency and beta- lactam and aminoglycoside resistance rates were found remarkably high in nosocomial P.aeruginosa strains isolated in our hospital. It was concluded that antibiotic resistance should be continously monitorized and necessary measures to prevent further increase in resistance should be promptly established.

BACKGROUND/AIMS: In this study, we investigated the Golgi protein 73 (GP73) level in Hepatitis B and determined the correlation between Hepatitis B virus (HBV) DNA, alanine aminotransferase (ALT), aspartate aminotransferase (AST) levels, and liver histopathology. Materials and. METHODS: GP73 levels were estimated by enzyme-linked immunosorbent assay in serum samples from patients. Liver biopsy specimens were examined by the same pathologist. RESULTS: : This study included a total of 127 patients who underwent liver biopsy. Of patients, 85% were HBeAg negative. HBV DNA level was median 134667 IU/mL (2247-170000000 IU/mL), Liver biopsy results revealed a mean Histological Activity Index (HAI) grade of 7.7 ± 3.4 and a mean fibrosis stage of 2.25 ± 1.06 gr/dL. GP73 was as follows: a mean of 14.8 ± 7.9 ng/mL and a median of 12.9 (4.8-50.1) ng/mL. A weak correlation between GP73 level and AST (r = 0.236, P = 0.11), fibrosis stage (r = 0.287, P = 0.002), and HAI grade (r = 0.218, P = 0.016) was noted. No statistically significant correlation was detected between GP73 and ALT (r = 0.16, P = 0.08), HBV DNA (r = 0.13, P = 0.08). CONCLUSION: Although recent studies revealed a strong correlation and increased GP73 levels in accordance with HAI scores and the fibrosis grade of liver, we detected a weak correlation between serum GP73 levels and HAI scores, fibrosis stage, and AST. This may be due to the insufficient number of patients with higher HAI grading and fibrosis staging in our study. Therefore, we concluded that, in cases of low-moderate fibrosis and HAI grading, GP73 seemed not to be useful and a reliable marker to replace liver biopsy.

The COVID-19 pandemic has brought countries' health services into sharp focus. It was drawn to our group's attention that healthcare workers (HCWs) had a lower mortality rate against higher COVID-19 incidence compared to the general population in Turkey. Since risk of exposure to tuberculosis bacillus among healthcare workers are higher than the population, we aimed to investigate if there is a relationship between BCG and Mycobacterium tuberculosis exposure history with COVID-19 severity in infected HCWs. This study was conducted with 465 infected HCWs from thirty-three hospitals to assess the relationship between COVID-19 severity (according to their hospitalization status and the presence of radiological pneumonia) and BCG and Mycobacterium tuberculosis exposure history. HCWs who required hospital admission had significantly higher rates of chronic diseases, radiological pneumonia, and longer working hours in the clinics. Higher rates of history of contact and care to tuberculosis patients, history of tuberculosis, and BCG vaccine were observed in hospitalized HCWs. HCWs who had radiological pneumonia had a significantly increased ratio of history of care to tuberculosis patients and a higher family history of tuberculosis. The findings from our study suggest that the lower mortality rate despite the more severe disease course seen in infected HCWs might be due to frequent exposure to tuberculosis bacillus and the mortality-reducing effects of the BCG vaccine.

In this study, we aimed to determine the late relapse rate in hepatitis C patients with sustained virological response after interferon-based regimens, and evaluated the predictors of late relapse while comparing the real-life data of our country with that of others. A multicenter retrospective study was performed to investigate the data of patients infected with HCV who obtained sustained virological response after classical or pegylated interferon alpha (PegIFNα) and ribavirin (RBV) for 48 weeks. Sustained virological response was based on negative HCV RNA level by PCR at the end of six months after the therapy. The information of patients enrolled in the study was retrieved from the hospital computer operating system and outpatient follow-up archives. We evaluated the age, gender, HCV RNA levels, HCV genotype, six-month and further follow-up of patients with sustained virologic response, presence of cirrhosis, steatosis and relapse. In all, 606 out of 629 chronic hepatitis C patients (mean age was 53±12 years; 57.6% of them were female) with sustained virological response were evaluated. We excluded 23 patients who relapsed within six months after the end of treatment (EOT). The mean follow-up period of the patients was 71 months (range: 6-136) after therapy. Late relapse rate was 1.8% (n=11) in all patients. Univariate Cox proportional hazard regression models identified that cirrhosis and steatosis were associated with the late relapse [(p = 0.027; Hazard Ratio (HR) 2.328; 95% confidence interval (CI): 1.309-80.418), (p = 0.021; HR 1.446; 95% CI: 1.243-14.510, respectively]. In multivariable Cox regression analysis, steatosis was the only independent risk factor for late relapse (p = 0.03; HR 3.953; 95% CI: 1.146-13.635). Although the late relapse rate was approximately 2% in our study, clinicians should consider that pretreatment steatosis may be an important risk factor for late relapse.

Sepsis is a severe clinical syndrome owing to its high mortality. Quick Sequential Organ Failure Assessment (qSOFA) score has been proposed for the prediction of fatal outcomes in sepsis syndrome in emergency departments. Due to the low predictive performance of the qSOFA score, we propose a modification to the score by adding age. We conducted a multicenter, retrospective cohort study among regional referral centers from various regions of the country. Participants recruited data of patients admitted to emergency departments and obtained a diagnosis of sepsis syndrome. Crude in-hospital mortality was the primary endpoint. A generalized mixed-effects model with random intercepts produced estimates for adverse outcomes. Model-based recursive partitioning demonstrated the effects and thresholds of significant covariates. Scores were internally validated. The H measure compared performances of scores. A total of 580 patients from 22 centers were included for further analysis. Stages of sepsis, age, time to antibiotics, and administration of carbapenem for empirical treatment were entered the final model. Among these, severe sepsis (OR, 4.40; CIs, 2.35-8.21), septic shock (OR, 8.78; CIs, 4.37-17.66), age (OR, 1.03; CIs, 1.02-1.05) and time to antibiotics (OR, 1.05; CIs, 1.01-1.10) were significantly associated with fatal outcomes. A decision tree demonstrated the thresholds for age. We modified the quick Sequential Organ Failure Assessment (mod-qSOFA) score by adding age (> 50 years old = one point) and compared this to the conventional score. H-measures for qSOFA and mod-qSOFA were found to be 0.11 and 0.14, respectively, whereas AUCs of both scores were 0.64. We propose the use of the modified qSOFA score for early risk assessment among sepsis patients for improved triage and management of this fatal syndrome.

BACKGROUND/AIM: Central line-associated bloodstream infections (CLABSIs) are associated with substantial morbidity and mortality and the infection rates vary in a wide range1397645907(high: 62.5%; low: 20%) in developing countries. We aimed to investigate the characteristics and the risk factors for mortality in patients with CLABSIs in intensive care units (ICUs) and provide the relevant data. MATERIALS AND METHODS: The electronic medical records database and file records obtained through active surveillance by an infection control committee of a hospital were screened to identify patients with CLABSIs hospitalized from January 2008 through July 2013. RESULTS: A total of 166 CLABSI episodes in 158 patients out of 17,553 on 38,562 catheter and 94,512 hospitalization days were evaluated. The infection developed in catheterized patients at a median of 14 days (range 2-88), and the highest infection rate with 13.4% (n = 20) was the femoral region among the places where the catheter was inserted. Of the patients catheterized, 54.4% survived whereas 45.6% died. In patients having Candida infection, the mortality was significantly higher. High APACHE II scores and Candida infections were found to be significant risk factors associated with mortality. CONCLUSION: APACHE II scores and bloodstream infection with Candida species were the most powerful predictors of mortality. In ICU practice, health-care givers must consider the emerging role of Candida for both invasiveness and mortality.
