Diabetic foot infections are one of the complications of diabetes mellitus resulting in extremity amputation and mortality. This study aimed to examine the predictive value of the C-reactive protein (CRP) to albumin ratio (CAR) for amputation risk in diabetic foot infection. Data from 178 patients were retrospectively examined. We found the cut point value of 15.45 according to the receiver operating characteristic (ROC) curve to show the predictive value of CAR for amputation risk in the overall population. We then divided the patients into two groups low (<15.45, n = 96) and high risk (≥15.45, n = 82) according to their CAR value. Matching based on propensity scores produced 64 patients in each group and showed that the amputation rate was high in the high-risk groups (50 vs 25%, P = .003). In the multivariate analysis in the matching group, previous amputation, antibiotic therapy in the last 3 months, and CAR (Odds ratio [OR]: 1.30, 95%Confidence interval [CI]: 1.01-1.45, P < .001) were independent predictors of amputation. These parameters may be useful to predict amputation risk in these patient groups., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflict of interest concerning the research, authorship, and/or publication of this article.

Background: Herein, we analyzed the efficacy of main antibiotic therapy regimens in the treatment of healthcare-associated meningitis (HCAM)., Materials/methods: This retrospective cohort study was conducted in 18 tertiary-care academic hospitals Turkey, India, Egypt and Romania. We extracted data and outcomes of all patients with post-neurosurgical meningitis cases fulfilling the study inclusion criteria and treated with empirical therapy between December 2006-September 2018., Results: Twenty patients in the cefepime + vancomycin-(CV) group, 31 patients in the ceftazidime + vancomycin-(CFV) group, and 119 patients in the meropenem + vancomycin-(MV) group met the inclusion criteria. The MV subgroup had a significantly higher mean Glasgow Coma Score, a higher rate of admission to the intensive care unit within the previous month, and a higher rate of antibiot herapy within the previous month before the meningitis episode (p < 0.05). Microbiological success on Day 3-5, end of treatment (EOT) clinical success (80% vs. 54.8%% vs 57.9%), and overall success (EOT success followed by one-month survival without relapse or reinfection 65% vs. 51.6% vs. 45.3%), EOT all cause mortality (ACM) and day 30 ACM (15% vs. 22.6% vs. 26%) did not differ significantly (p > 0.05) among the three cohorts. No regimen was effective against carbapenem-resistant bacteria, and vancomycin resulted in an EOT clinical success rate of 60.6% in the methicillin-resistant staphylococci or ampicillin-resistant enterococci subgroup (n = 34)., Conclusions: Our study showed no significant difference in terms of clinical success and mortality among the three treatment options. All regimens were ineffective against carbapenem-resistant bacteria. Vancomycin was unsuccessful in approximately 40% of cases involving methicillin-resistant staphylococci or ampicillin-resistant enterococci., (© 2023. BioMed Central Ltd., part of Springer Nature.)

Objectives: There are limited data about nosocomial coinfections of COVID-19 cases monitored in the intensive care unit. This study aims to investigate coinfections in COVID-19 patients followed in an intensive care unit of a university hospital., Methods: This study analyzed retrospectively the data of coinfections of 351 COVID-19 patients in the period 28.02.2020-15.01.2021 in a tertiary care intensive care unit in a university hospital., Results: Bacterial coinfections were present in 216 of the 351 cases. One hundred and thirty of these cases were evaluated as nosocomial infections. On the third day the Sequential Organ Failure Assessment Score, usage of invasive mechanical ventilation and presence of septic shock were significantly higher in the coinfected group. The neutrophil/lymphocyte ratio, polymorphonuclear leukocyte count, procalcitonin, ferritin, and blood urea nitrogen values were significantly higher in the coinfection group. White blood cells (WBC) (OR: 1.075, 95% CI 1.032-1.121, p = 0.001) and ICU hospitalization day (OR: 1.114, 95% CI 1.063-1.167, p < 0.001) were found to be independent risk factors for coinfection in the multivariate logistic regression analysis. The rates of hospitalization day on the day of arrival, the 21st day, as well as total mortality (p = 0.004), were significantly higher in the coinfected group., Conclusion: Bacterial coinfections of COVID-19 patients in the intensive care unit remain a problem. Identifying the infectious agent, classifying colonizations and infections, and using the proper treatment of antibiotics are of great importance in the case management of COVID-19 patients in the intensive care unit., (© 2023.

Aim: To examine the variables associated with mortality in patients with Acinetobacter baumannii-related central nervous system infections treated with intrathecal colistin., Materials and Methods: This multi-centre retrospective case control study included patients from 11 centres in Turkey, as well as cases found during a literature review. Only patients with CNS infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii treated with intrathecal colistin were included in this study. The variables associated with mortality were determined by dividing the patients into groups who died or survived during hospitalisation, and who died or survived from Acinetobacter meningitis., Results: Among the 77 cases enrolled in the study, 35 were found through a literature review and 42 were cases from our centres. Forty-four cases (57.1%) were male and the median age was 48 years (range: 20-78 years). Thirty-seven patients (48%) died during hospitalisation. The variables associated with increased all-cause mortality during hospitalisation included old age (odds ratio, 1.035; 95% confidence interval (CI), 1.004-1.067; p=0.026) and failure to provide cerebrospinal fluid sterilisation (odds ratio, 0.264; 95% confidence interval, 0.097-0.724; p=0.01). There is a trend (P=0.062) towards higher mortality with using of meropenem during meningitis treatment. Fifteen cases (19%) died from meningitis. There were no significant predictors of meningitis-related mortality., Conclusions: The mortality rate for central nervous system infections caused by multidrug-resistant or extensively drug-resistant Acinetobacter baumannii is high. Old age and failure to provide CSF sterilisation are associated with increased mortality during hospitalisation., (Copyright © 2016. Published by Elsevier B.V.)

Objectives: To compare the efficacy of colistin (COL) monotherapy versus non-COL based combinations in the treatment of bloodstream infections (BSIs) due to multidrug resistant Acinetobacter spp.(MDR-A)., Materials and Methods: Retrospective data of 107 MDR-A BSI cases from 27 tertiary centers in Turkey were included., Primary End-Point: 14-day mortality., Secondary End-Points: Microbial eradication and clinical improvement., Results: Thirty-six patients in the COL monotherapy (CM) group and 71 in the non-COL based combinations (NCC) group were included in the study. Mean age was 59.98 ± 20 years (range: 18-89) and 50.5% were male. Median duration of follow-up was 40 days (range: 9-297). The 14-day survival rates were 52.8% in CM and 47.23% in NCC group (P = 0.36). Microbiological eradication was achieved in 69% of CM and 83% of NCC group (P = 0.13). Treatment failure was detected in 22.9% of cases in both CM and NCC groups. Univariate analysis revealed that mean age (P = 0.001), Charlson comorbidity index (P = 0.03), duration of hospital stay before MDR-A BSI (P = 0.04), Pitt bacteremia score (P = 0.043) and Acute Physiology and Chronic Health Evaluation II score (P = 0.05) were significant in terms of 14-day mortality. Advanced age (P = 0.01) and duration of hospital stay before MDR-A BSI (P = 0.04) were independently associated with 14-day mortality in multivariate analysis., Conclusion: No significant difference was detected between CM and non-COL based combinations in the treatment of MDR-A BSIs in terms of efficacy and 14-day mortality.

Infective endocarditis caused by Gemella morbillorum is a rare disease. In this report 67-year-old male patient with G. morbillorum endocarditis was presented. The patient was hospitalized as he had a fever of unknown origin and in the two of the three sets of blood cultures taken at the first day of hospitalization G. morbillorum was identified. The transthoracic echogram revealed 14 × 10 mm vegetation on the aortic noncoronary cuspis. After 4 weeks of antibiotic therapy, the case was referred to the clinic of cardiovascular surgery for valve surgery.

A major proportion of the global HIV infections is caused by group M of HIV-1 genotype and to date approximately nine subtypes (A, B, C, D, F, G, H, J, K) and 50 circulating recombinant forms (CRFs) have been recognized. Recombinants between different HIV-1 group M subtypes are designated as CRF. The extension 'cpx', for complex, is given if the CRF consists of contributions from three or more different subtypes but the composition of the subtype is not given. The objective of this study was to present, for the first time an HIV-1 positive married couple infected with CRF06&#95;cpx subtype in Izmir, Turkey. A 39-year-old male patient who admitted to hospital with the complaints of oral candidiasis and zona, was found to be anti-HIV positive. CD4+ T lymphocyte count was 21 cells/mm3 and plasma HIV-1 RNA level was 56.380 copies/ml. He reported unprotected heterosexual contact with multiple partners including African women during his stay in Saudi Arabia between 1996 and 2002. After his diagnosis, his 37-year-old wife was screened for HIV infection and she was also found anti-HIV positive, with CD4+ T cell count of 122 cells/mm3. However, her results of basal plasma HIV-1 RNA could not be obtained because of an internal control error. HIV-1 strains were analysed for subtyping, recombination and drug resistance mutations with pol gene region sequencing. HIV-1 sequences were subtyped as CRF06&#95;cpx after phylogenetic analysis using neighbor-joining method. According to the recombination analysis, HIV-1 pol gene regions consisted of group M subtype G, A, D, and B in the male patient and G K, A, F, and D in the female patient. While L10I + L33F mutation associated with protease inhibitor (PI) resistance was detected in both of the patients, K219N mutation associated with nucleoside reverse transcriptase inhibitor (NRTI) resistance was detected only in the male patient. In conclusion, HIV-1 molecular epidemiology studies are important tools for tracking transmission patterns and the spread of CRF. Global monitoring of CRF subtypes is also important to supply data for HIV vaccine development studies. On the other hand, the detection of HIV-1 primary resistance mutations in antiretroviral naive patients suggested that the resistance testing should be an integral part of the management of HIV infection.

The aims of this study were to evaluate the attitudes towards H1N1 vaccination and to determine the safety and side effects following 2009 pandemic influenza A (H1N1) vaccination. Pandemic influenza vaccine had been administered to the healthcare personnel in our research and training hospital in December 2009. The rate being vaccinated was established as 40% (800/2000). Four months following vaccination, the opinions about vaccination were asked to the healthcare workers, and also side effects were questioned to the vaccinated group. Two different questionnaires (for vaccinated and unvaccinated subjects) were delivered to the volunteers who agreed to participate in the study. Demographic features, reasons related to being vaccinated or not, were questioned. The vaccinated group was also questioned for the presence of chronic diseases, previous vaccinations (pandemic/seasonal influenza), local or systemic reactions that develop after vaccination. A total of 332 volunteers participated in the questionnaire. Of them 247 (74.4%) were vaccinated and 85 (25.6%) were unvaccinated. Male/female ratio of the participants was 1.2, and 55.7% of them were older than 30-year-old. Most of the participants (82.8%) were highly educated (high school and faculty-graduated). Vaccination rates were found statistically significant in advanced age group compared to young adults (p= 0.042); in male gender compared to females (p= 0.001) and in parents compared to subjects who didn't have children (p= 0.021). Vaccination rates were observed to be higher (57.5%) in non-medical staff (cleaning employers, administrative personnel, etc.) than the physicians (29.1%) and nurses (13.4%), and the rate was also high (54.7%) in personnel who worked in intensive care units, emergency department and administrative units than the personnel who worked in the clinics of internal medicine (22.3%) and surgery (23.1%) (p= 0.001). The most important causes of rejecting vaccination were being afraid of the side effects (69.4%) and not believing the effectiveness of the vaccine (56.4%). The leading causes of accepting vaccination were worries about infecting their family (60.3%) and being in a risk group (54.3%). After vaccination, local reactions (pain, swelling and redness at the vaccination site) were described in 43.3% and systemic reactions (weakness, fatigue, muscle aches, influenza-like symptoms, etc.) were described in 43.7% of the subjects. Severe side effects such as vasculitis, neuritis, encephalomyelitis, Guillian-Barre syndrome and anaphylactic reaction were not observed in any of the vaccinated cases. It was detected that worries about the safety of vaccine had negative impact for vaccination. Since no serious side effects were detected related to vaccination, it was concluded that the vaccine was safe. In spite of the scientific proofs, negative concerns about the safety of the vaccines can unfavorably affect the vaccination campaigns and can jeopardize efforts of influenza control. As a result, data collection systems about the safety and side effects of the vaccine all over the country and regular reports about these data may more efficiently guide vaccination programs in the future.
