RESUMEN

Hepatitis B virus (HBV) infection is a global health problem leading to cirrhosis, hepatocellular carcinoma, and liver failure. The Hepatitis B vaccine plays a significant role in reducing the incidence of HBV worldwide. Approximately 5-10% of vaccinated people do not produce protective antibody levels. Nuclear factor kappa B (NF­κB) mediates inflammatory responses through pro-inflammatory cytokines. However, the role of the NF­κB signaling pathway and its association with pro-inflammatory cytokines in hepatitis B vaccine response is unclear. We aimed to assess changes in the IL1A, IL6, IL12A, TNF-α, and NFκB1 expression levels in the non-responder and responder. A total of 32 non-responders and 36 responders were included in the study. The expression level of determined genes was analyzed by RT-PCR. Our results showed that IL1A, IL6, IL12A, and NFκB1 mRNA levels significantly increased in the non-responders compared to the responders (p < .01). Furthermore, there was a significant correlation between IL1A, IL6, TNF-α, and NFκB1 in the non-responder and responders. In conclusion, inflammatory signaling pathways may play an important role in response to HBV vaccine. Therefore, NF­κB signaling and associated pro-inflammatory cytokine mRNA levels could predict hepatitis B vaccine response. However, the underlying molecular mechanisms of hepatitis B vaccine immunity need further investigation.

RESUMEN

BACKGROUND: To have country-wide information about multidrug resistance (MDR) in isolates from community-acquired urinary tract infections (CAUTI) of Turkey, in terms of resistance rates and useful options. METHODS: We used a geocode standard, nomenclature of territorial units for statistics (NUTS), and a total of 1588 community-acquired isolates of 20 centres from 12 different NUTS regions between March 2019 and March 2020 were analysed. RESULTS: Of the 1588 culture growths, 1269 (79. 9%) were Escherichia coli and 152 (9.6%) were Klebsiella spp. Male sex, advancedage, and having two or more risk factors showed a statistically significant relation with MDR existence (p < 0.001, p: 0.014, p < 0.001, respectively) that increasing number of risk factors or degree of advancing in age directly affects the number of antibiotic groups detected to have resistance by pathogens. In total, MDR isolates corresponded to 36.1% of our CAUTI samples; MDR existence was 35.7% in E. coli isolates and 57.2% in Klebsiella spp. isolates. Our results did not show an association between resistance or MDR occurrence rates and NUTS regions. DISCUSSION: The necessity of urine culture in outpatient clinics should be taken into consideration, at least after evaluating risk factorsfor antibacterial resistance individually. Community-acquired UTIs should be followed up time- and region-dependently. Antibiotic stewardship programmes should be more widely and effectively administrated.

RESUMEN

The efficacy of the inactivated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine has not been fully elucidated across the whole spectrum of patients on kidney replacement therapy. We aimed to characterize the long-term antibody response of inactivated SARS-CoV-2 vaccine administered in kidney transplant recipients (KTRs) and hemodialysis (HD) patients. We performed this prospective observational study in 50 HD, 64 KTR, and 41 healthy control groups (HG) given two doses of CoronaVac. We measured anti-Spike antibodies after 28 days of every vaccine dose, 3rd and 6th months after the first dose, and compared them between cohorts. After two doses, an anti-spike immunoglobulin G of ≥50 AU/ml was present in HD, KTR, and HG as 44%, 7.2%, and 58.5%, respectively (p < 0.001). Furthermore, the proportion of antibody titers peaked at 86.5%, 23%, and 97.6% (p < 0.001) at the 3rd month and decreased significantly at the 6th month in most HD and HG participants, whereas this effect was not observed in KTRs from basal until the 6th month (p < 0.001). During the follow-up, the incidence of coronavirus disease 2019 disease was higher (p < 0.003) in KTRs compared to the other groups, but there was no requirement for an intensive care unit and no death was recorded. We found a negative correlation between antibody seroconversion and age (p < 0.016). The antibody response following inactivated vaccine in dialysis patients is almost comparable to controls for 6 months. In contrast, kidney transplant patients have a poor response. These findings reinforce the need to discuss the vaccination strategy in immunocompromised patients, including the third dose with homologous or heterologous vaccines.

RESUMEN

BACKGROUND: Gallbladder and biliary tract infections are diseases with high mortality rates if they are not treated properly. Microbiological evaluation of perioperatively collected samples both ensures proper treatment of patients and guides empirical treatment due to the determination of microorganism susceptibility. AIMS: This study aimed to isolate the microorganisms in bile cultures from patients who underwent cholecystectomy and to determine sensitivity results of these microorganisms. METHODS: This study was a multi-center and prospective design, included 360 patients, and was performed between 2019 and 2020. Culture results of bile taken during cholecystectomy were evaluated. RESULTS: Bacterial growth was found in the bile cultures of 84 out of 360 (23.3%) patients. Patients were divided into two groups according to whether they had risk factors for resistant microorganisms or not. While Escherichia coli (n = 11, 13%), Enterococcus spp. (n = 8, 9.5%), and Enterobacter spp. (n = 4, 4.7%) were detected most frequently in patients without risk. Staphylococcus spp. (n = 17, 20.2%), Enterococcus spp. (n = 16, 19%), and E. coli (n = 8, 9.5%) were the most frequently found microorganism at-risk patients. In multivariate analysis, bile culture positivity was found higher in patients who had history of biliary disease (p = 0.004), operation performed concurrently with a cholecystectomy (p = 0.035), and high rate of polymorphonuclear leukocytes (PNL) in total leukocyte count (p = 0.001). CONCLUSIONS: Our study shows that when starting empirical antibiotic treatment for bile ducts, whether patients are at risk for the development of resistant bacterial infection should be evaluated after which antibiotic selection should be made accordingly.

RESUMEN

BACKGROUND: Diagnosis with reverse transcriptase polymerase chain reaction (RT-PCR) test is a very important step for the control of the COVID-19 pandemic. The aim of this study is to compare the RT-PCR results of the samples taken directly from the viral transport medium (VTM) without extraction with the RT-PCR results of two different extraction methods, one automated and the other manual, in the diagnosis of COVID-19. METHODS: Among the respiratory tract samples sent to Sakarya Training and Research Hospital Microbiology Laboratory for COVID-PCR study, 20 negative and 43 positive samples with different cycle threshold (CT) values were included in the study. Both manual nucleic acid isolation with the vNAT isolation kit (Bioeksen, Turkey) and automatic nucleic acid isolation with the EZ1 Virus Mini Kit v2.0 in the isolation device were performed simulta-neously from the patient samples included in the study and the results were compared. RESULTS: The mean Ct values of the samples were found to be 21.58 using manual vNAT as the extraction method, 17.63 using the automated magnetic bead method, and 21.45 in PCR from direct VTM without extraction. When the automatic magnetic beads extraction method was taken as the reference method, the sensitivity of direct PCR was 97.3%, the specificity was 95%, the positive predictive value was 97.3%, and the negative predictive value was 95%. Phi coefficients were found to be 0.927 between vNAT and direct PCR, 1 between vNAT and EZ1, and 0.922 between direct PCR and EZ1. CONCLUSIONS: Direct PCR has advantages such as eliminating RNA extraction and purification steps, providing a shorter detection time, and using less labor and less consumables without reducing the diagnostic accuracy. It is thought that this method can help as a useful process management for the control of the epidemic in countries with limited resources.

RESUMEN

BACKGROUND: This study aimed to investigate the specific risk factors for the transmission of novel coronavirus (SARS-CoV-2) among healthcare workers in different campuses of a university hospital and to reveal the risk factors for antibody positivity. METHODS: In this retrospective cross-sectional study, 2988 (82%) of 3620 healthcare workers in a university hospital participated. The coronavirus disease 2019 (COVID-19) antibody was investigated using serum from healthcare workers who underwent COVID-19 antibody testing. The antibody test results of the participants were evaluated based on their work campus, their profession and their workplace. The statistical significance level was p < 0.05 in all analyses. RESULTS: Of the participants in this study, 108 (3.6%) were antibody positive, and 2880 (96.4%) were negative. Antibody positivity rates were greater in nurses compared with other healthcare workers (p < 0.001). Regarding workplace, antibody positivity was greater in those working in intensive care compared to those working in other locations (p < 0.001). CONCLUSIONS: Healthcare workers are at the highest risk of being infected with COVID-19. Those who have a higher risk of infection among healthcare workers and those working in high-risk areas should be vaccinated early and use personal protective equipment during the pandemic. TRIAL REGISTRATION: Retrospective permission was obtained from both the local ethics committee and the Turkish Ministry of Health for this study (IRB No:71522473/050.01.04/370, Date: 05.20.2020).

RESUMEN

BACKGROUND: HIV (human immunodeficiency virus), causing acquired immunodeficiency syndrome (AIDS), is one of the most important health problems in the world. Certain cytokines produced during the cytokine storm in an acute infection can be biomarker candidates. The strong association of IFN-γ inducible protein 10 (IP-10) with low CD4 cell counts suggests that it can be an acute phase biomarker. METHODS: In this study, IP-10 was monitored at routine controls during pre-treatment and/or in subsequent phases of treatment, and its correlation with CD4 cell count and viral load was assessed. Venous blood samples, taken from 30 patients (at 0 - 3 - 6 months), and 20 healthy volunteers, were sent to the Laboratory for flow cytometry, nucleic acid tests (NAT) and ELISA tests. RESULTS: The mean IP-10 concentration of patients was 344 pg/mL, and these values for the untreated, treated and control groups were 422 pg/mL and 210 pg/mL and 68 pg/mL respectively. A statistically significant difference was found between the IP-10 values of the patient and control groups (p = 0.006). There was a significant, positive and moderate relation between IP-10 and viral load values (r = 0.59, p < 0.001), while there was a significant, negative and moderate relation between IP-10 and CD4 cell count (r = -0.51, p < 0.001). CONCLUSIONS: IP-10 levels in early HIV-1 patients, which are shown to be closely related to CD4 cell levels and viral replication, may be an alternative or support marker compared to the more expensive viral load tests in monitor-ing viremia changes and response to antiretroviral treatment.

RESUMEN

Background/aim: There is no study in the literature in which only chest computed tomography (CT) findings of deceased cases obtained at admission were examined, and the relationship between these findings and mortality was evaluated. Materials and methods: In this retrospective study, a total of 117 deceased patients with COVID-19 infection confirmed by positive polymerase chain reaction and undergone chest CT were enrolled. We evaluated initial chest CT findings and their relationship, location, prevalence, and the frequency with mortality. Results: The mean age of patients was 73 ±18 years; 71 of all patients were male and 46 were female. The predominant feature was pure ground-glass opacity (GGO) lesion (82.0%), and 59.8% of cases had pure consolidation. There was no cavitation or architectural distorsion. Pericardial effusion was found in 9.4% the patients, and pleural effusions were found in 15.3% of them. Mediastinal lymphadenopathy was only 11.9% in total. Conclusion: In deceased patients, on admission CTs, pure consolidation, pleural and pericardial effusion, mediastinal LAP were more common than ordinary cases. It was these findings that should also raise the concern when they were seen on chest CT; therefore, these radiologic features have the potential to represent prognostic imaging markers in patients with COVID-19 pneumonia.

RESUMEN

Background/aim: During the intense periods of the COVID-19 pandemic, legal measures were taken for its containment. However, since legal precautions cannot be implemented continuously, hand washing, mask usage and obeying social distance rules are important in combating the pandemic. Complying with these rules is mostly individual decisions. The behavior of individuals has a prominent place in the course of the pandemic. In this study, we aimed to develop a scale which could measure compliance with outbreak measures. Materials and methods: This study was conducted in two stages after evaluation of the content validity of the item pool formed by the research group by experts. For construct validity, the scale subdimensions were determined in 250 people between the ages of 18-70 years at the first stage and the definitive version of the 20-item scale was constructed. In the second stage, exploratory factor analysis was repeated in a group of 484 people, and confirmatory factor analysis was performed. Cronbach's alpha coefficients, Spearman-Brown coefficients, test-retest methods were used to determine reliability. Results: The variance explanation of the scale consisting of 20 items and two subdimensions in the explanatory factor analysis is 63.434% (n = 484). Confirmatory factor analysis resulted in CMIN/DF = 3.540, RMR = 0.043, NFI Delta 1 = 0.928, TLI rho 2 = 0.939, CFI = 0.947, RMSEA = 0.072, SRMR = 0.0368. Cronbach's alpha value of the scale is 0.95; and the Spearman Brown coefficient equal length analysis resulted in 0.928. The temporal consistency of the scale was evaluated with the test-retest method (P = 0.893). The structure, content validity, temporal consistency, item discrimination, and internal consistency were evaluated and found to have acceptable valid, reliable properties. Conclusion: The outbreak prevention recommendation compliance scale is a valid and reliable tool with which compliance with the prevention plans can be evaluated.

RESUMEN

Background/aim: In this study, we aim to investigate the efficacy of convalescent plasma (CP) according to blood groups (BGs) in the treatment of critically ill patients diagnosed with COVID-19. Materials and methods: Twenty-eight critically ill and laboratory-confirmed COVID-19 patients who were admitted to the intensive care unit (ICU) of Sakarya University, Medical Faculty were included in the study. Patients were divided into 2 groups: patients who received anti-A antibody (Ab) containing CP (BG O and B) and those who did not receive CP containing anti-A Ab (BG A and AB). Results: Among the 28 patients, 13 patients received anti-A Ab containing CP (BG; B: 6, O: 7) and 15 patients did not receive anti-A Ab CP (BG; A: 13, AB: 2). Duration in ICU, the rates of mechanical ventilation (MV) support and vasopressor support, the case fatality rate, and the discharge rate were lower in patients who received CP containing anti-A Ab than not containing anti-A Ab CP. However, only the difference in the rate of MV support achieved statistically significance (P = 0.04) Conclusion: In our study, it was observed that the efficiency of CP without anti-A antibody was lower than that of plasma containing anti-A antibody, although it was not statistically significant. This result is thought to be due to the anti-A antibody's ability to block the ACE2 receptor. We believe that this hypothesis should be investigated in controlled studies with higher patient numbers.

RESUMEN

Background/aim: The COVID-19 infection, which started in Wuhan City, China, in December 2019, turned into a pandemic in a very short time, affecting mainly the elderly and those with serious chronic illnesses. COVID-19 infections have been observed to have a high mortality rate, especially in patients undergoing maintenance hemodialysis. Materials and methods: Forty-two patients over 18 years of age who underwent a maintenance hemodialysis program at our unit, who tested positive for COVID-19 by PCR from nasopharyngeal swabs, and/or who were observed to have disease-related signs in their CTs were included in the study. Results: In this study, 23 of 42 patients receiving hemodialysis support in our clinic were included. The median age was 67 years old (min: 35; max: 91 years), and all of our patients had primary hypertension and other comorbidities. Their clinical evaluation showed that dry cough (47.8%) and shortness of breath (47.8%) were the most common symptoms. Fever was less pronounced (30.4%). The median time from the onset of symptoms to hospitalization was 1 day (min: 0; max:), and the time from hospitalization to death was 18 days (min: 1; max: 22). Transfer from the inpatient ward to the ICU took a median of 7 days (min: 1; max: 13). Among the 23 patients, 3 died during follow-up, and 20 were discharged with full recovery. Baseline ferritin, procalcitonin levels, and CRP/albumin rates were higher, and neutrophil/lymphocyte levels were lower in patients who eventually died. In these patients, despite being nonsignificant, there were more diabetic patients, and the D-dimer levels were higher than 1000 ugFEU/L. Conclusion: The COVID-19 infection is associated with increased mortality in chronic kidney diseases patients. Despite being nonsignificant, there was a trend towards increased mortality in patient with diabetes, D-dimer levels >1000 ugFEU/L, higher ferritin and prokalsitonin levels, an increased CRP/albumin ratio, and a lower neutrophil/lymphocyte ratio.

RESUMEN

Background/aim: It is very important for the efficient use of limited capacity and the success of treatment to predict patients who may need ICU with high mortality rate in the Covid-19 outbreak. In our study, it was aimed to investigate the value of the radiological involvement on initial CT in demonstrating the ICU transfer and mortality rate of patients. Materials and methods: All PCR-positive patients were included in the study, whose CT, PCR, and laboratory values were obtained simultaneously at the time of first admission. Patients were divided into 4 groups in terms of the extent of radiological lesions. These groups were compared in terms of intensive care transfer needs and Covid-related mortality rates. Results: A total of 477 patients were included in the study. Ninety of them were group 0 (no lung involvement), 162 were group 1 (mild lesion), 89 were group 2 (moderate lesion), and 136 were group 3 (severe lung involvement). A significant relationship was found between the extensiveness of the radiological lesion on CT and admission to intensive care and mortality rate. As the initial radiological involvement amounts increased, the rate of ICU transfer and mortality increased. The mortality rates of the groups were 0%, 3%, 12.3%, and 12.5%, respectively, and the difference was significant (p < 0.001). Similarly, the ICU transfer rates of the groups were 2.2%, 5.6%, 13.5%, and 17.7%, respectively, and the difference was significant (p < 0.001). Conclusion: In conclusion, in our study, the strong relationship between the initial radiological extent assessment and the need for intensive care and mortality rates has been demonstrated, and we believe that our results will make a significant contribution to increase the success of the health system in predicting patients who may progress, helping clinicians and managing pandemics.

RESUMEN

Background/aim: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was first reported in Turkey on March 10, 2020 and the number of the patients are increasing day by day. Coronavirus disease 2019 (Covid-19) has high mortality rates in intensive care units (ICUs). We aimed to describe the demographic characteristics, comorbidities, treatment protocols, and clinical outcomes among the critically ill patients admitted to the ICU of our hospital. Materials and methods: This cohort study included 103 consecutive patients who had laboratory confirmed Covid-19 and admitted to ICU of Sakarya University Training and Research Hospital between March 19 and April 13, 2020. The final date of the follow-up was April 18. Results: The mean age of the patients was 69.6 ± 14.1 years. Most of the patients had increased CRP (99%), serum ferritin (73.8%), d-dimer (82.5%), and hs-troponin levels (38.8%). 34 patients (33%) had lymphocytopenia, 24 patients (23.3%) had thrombocytopenia. 63 patients (61.2%) developed acute respiratory distress syndrome (ARDS), 31 patients (30.1%) had acute kidney injury, and 52 patients (50.5%) had multiple organ dysfunction syndrome (MODS) during follow-up. Sixty-two patients (60.2%) received mechanical ventilation. As of April 18, of the 103 patients, 52 (50.5%) had died, 30 (29.1%) had been discharged from the ICU, 21 (20.4%) were still in the ICU. Conclusions: Covid-19 has high mortality rates in ICU. Patients with elevated procalcitonin, hs-troponin, d-dimer, and CRP levels and lower platelet count at admission have higher mortality.

RESUMEN

Background/aim: We aimed to identify clinical settings of renal transplant patients with COVID-19. Materials and methods: In this retrospective study, we included kidney transplant inpatients with laboratory confirmed COVID-19 who had been discharged or had died by October 1st, 2020. Characteristics of the patients, including basal and last outpatient biochemical parameters were recorded. Discontinuation or dosage reduction of immunosuppressives and other treatment information was documented. Results: Twenty patients were included in this study, of whom 18 were discharged and 2 died in hospital. The mean duration of hospitalization and follow-up were 9.7 ± 6.4 days and 4.5 ± 2.0 months, respectively. Fourteen patients (70%) were male and mean age was 48.0 ± 10.3 years. At admission, all had immunosuppression withdrawn and were started on methylprednisolone 16 mg/ day (50%) or dexamethasone (50%). Tacrolimus/m-TOR inhibitors were reduced by 50% and all antimetabolites were discontinued. Hemodialysis was needed for 10% of patients. Acute kidney injury was detected in 25% of the patients. With respect to hospitalization time and complications, there was no significant difference between patients who used dexamethasone and those who did not (P > 0.05). The discontinued immunosuppressives were resumed within 2 to 4 weeks after discharge according to the severity of disease. No rehospitalization or acute rejection was detected during the follow-up of the patients. Conclusion: Renal transplant patients are considered a high risk group for COVID-19. It can be said that discontinuation or reducing dosages of immunosuppressives may be effective and safe in kidney transplant patients.

RESUMEN

Ventilator-associated pneumonia (VAP) due to Acinetobacter spp. is one of the most common infections in the intensive care unit. Hence, we performed this prospective-observational multicenter study, and described the course and outcome of the disease. This study was performed in 24 centers between January 06, 2014, and December 02, 2016. The patients were evaluated at time of pneumonia diagnosis, when culture results were available, and at 72 h, at the 7th day, and finally at the 28th day of follow-up. Patients with coexistent infections were excluded and only those with a first VAP episode were enrolled. Logistic regression analysis was performed. A total of 177 patients were included; empiric antimicrobial therapy was appropriate (when the patient received at least one antibiotic that the infecting strain was ultimately shown to be susceptible) in only 69 (39%) patients. During the 28-day period, antibiotics were modified for side effects in 27 (15.2%) patients and renal dose adjustment was made in 38 (21.5%). Ultimately, 89 (50.3%) patients died. Predictors of mortality were creatinine level (OR, 1.84 (95% CI 1.279-2.657); p = 0.001), fever (OR, 0.663 (95% CI 0.454-0.967); p = 0.033), malignancy (OR, 7.095 (95% CI 2.142-23.500); p = 0.001), congestive heart failure (OR, 2.341 (95% CI 1.046-5.239); p = 0.038), appropriate empiric antimicrobial treatment (OR, 0.445 (95% CI 0.216-0.914); p = 0.027), and surgery in the last month (OR, 0.137 (95% CI 0.037-0.499); p = 0.003). Appropriate empiric antimicrobial treatment in VAP due to Acinetobacter spp. was associated with survival while renal injury and comorbid conditions increased mortality. Hence, early diagnosis and appropriate antibiotic therapy remain crucial to improve outcomes.

RESUMEN

BACKGROUND: Hepatitis E virus (HEV) infection is usually an acute self-limiting disease, which causes rapidly progressive cirrhosis and chronic infection in patients with hematological malignancies, patients requiring chemotherapy, and HIV-infected patients. The aim of this study was to investigate the positivity of hepatitis E IgM and IgG in HIV positive patients with the recently introduced Enzyme Linked Fluorescent Assay (ELFA) commercial kits. MATERIALS AND METHODS: The study included 126 patients who were followed up by the Infectious Diseases and Clinical Microbiology Clinic of Sakarya University Training and Research Hospital between October 2017 and December 2018 for HIV positivity. Serum samples of the patients were evaluated for anti-HEV IgG and IgM positivity with a novel commercially available kit using the ELFA method (bioMerieux, France). The study group consisted of 126 patients with HIV infection. Anti-HEV IgG antibodies were studied primarily from plasma samples. Anti-HEV IgM positivity was also investigated in patients with anti-HEV IgG positivity. RESULTS: The study group consisted of 114 (90.5%) males and 12 (9.5%) females with a mean age of 38.11 ± 13.32 (min: 18, max: 80) years. Anti-HEV IgG was positive in 5 (4.0%) HIV-positive patients. One of the anti-HEV IgG positive patients was newly diagnosed with HIV and the other four patients were being followed up for HIV positivity. Anti-HEV IgM was negative in all patients. None of the patients with anti-HEV IgG positivity had anti-HCV and HBsAg positivity. CONCLUSIONS: In the study, anti-HEV IgG positivity was found to be 4% in HIV-positive individuals, and no HCV and HBV co-infection was detected in any patients with HIV and HEV coexistence. HEV infections do not emerge as a priority among HIV-infected people, but HEV should also be investigated in HIV-infected individuals with liver abnormalities of uncertain etiology.

RESUMEN

BACKGROUND: The first case of a novel coronavirus (COVID-19) infection was detected in Wuhan, fever and respiratory symptoms have been frequently reported in patients infected with this virus. AIM: It was aimed to compare the symptoms of patients with COVID-19 positivity and patients without COVID-19 positivity hospitalized with suspicion of COVID-19. METHODS: Patients presenting to the Sakarya University Training and Research Hospital with suspicion of COVID-19 were included in the study. Samples were obtained from the patients and PCR tests were performed; the patients were grouped as COVID-19 positive and COVID-19 negative; these two groups were questioned for 15 symptoms and the results were compared. RESULTS: A total of 297 patients with suspicion of COVID-19 were included in the study. COVID-19 was positive in 143 patients and negative in 154 patients. The most common symptoms in the COVID-19 positive group were: cough (56.6%), weakness (56.6%), taste disorder (35.7%), myalgia (34.3%), and fever (33.6%); and in the COVID-19 negative group: cough (63%), weakness (45.5%), dyspnea (29.9%), headache (27.3%) and fever (24.7%). When these two groups were compared, taste disorder, smell disorder and diarrhea were significantly higher in the COVID-19 positive group (p = <0,00001, p = 0,00001 and p = 0,02). CONCLUSION: Our study showed that taste and smell disorders and diarrhea were important markers in COVID-19 infection.

RESUMEN

Five oxypropanol amine derivatives that four of them are novel have been synthesized with high yields and practical methods. in vitro antibacterial susceptibility of Acinetobacter baumannii, Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus strains to synthesized substances were evaluated with agar well-diffusion method by comparison with commercially available drugs. Most of the bacteria were multidrug resistant. It was concluded that these compounds are much more effective than reference drugs. These eugenol bearing oxypropanolamine derivatives were also effective inhibitors against α-glycosidase, cytosolic carbonic anhydrase I and II isoforms (hCA I and II), and acetylcholinesterase (AChE) enzymes with Ki values in the range of 0.80 ±â€¯0.24-3.52 ±â€¯1.01 µM for hCA I, 1.08 ±â€¯0.15-3.64 ±â€¯0.92 µM for hCA II, 5.18 ±â€¯0.84-12.46 ±â€¯2.08 µM for α-glycosidase, and 11.33 ±â€¯2.83-32.81 ±â€¯9.73 µM for AChE, respectively.

RESUMEN

BACKGROUND: In terms of pediatric healthcare-associated infections (HAI), neonatal intensive care units (NICU) constitute the greatest risk. Contacting a health care personnel, either directly or indirectly, elevates NICU occurrence rate and risks other infants in the same unit. In this study, it is aimed to retrospectively analyze the effect of the training along with camera monitoring and feedback (CMAF) to control the infection following a small outbreak. METHODS: ESBL producing Klebsiella pneumoniae was detected on three infants in May 2014 at the isolation room of Sakarya University Hospital NICU. Precautions were taken to prevent further spread of the infection. The infected infants were isolated and the decolonization process was initiated. For this aspect, health care workers (HCWs) in NICU were trained for infection control measures. An infection control committee has monitored the HCWs. Before monitoring, an approval was obtained from the hospital management and HCWs were informed about the CMAF, who were then periodically updated. On a weekly basis, NICU workers were provided with the feedbacks. Epidemic period and post-epidemic control period (June-July-August 2014) were evaluated and p value < 0.05 was considered statistically significant. RESULTS: Healthcare-associated infection (HAI) density was 9.59% before the onset of the CMAF, whereas it was detected as 2.24% during the CMAF period (p < 0.05). Following the precautions, HAI and HAI density rates have reduced to 76.6% and 74.85%, respectively. Moreover, hand hygiene compliance of health care workers was found 49.0% before the outbreak, whereas this rate has elevated to 62.7% after CMAF. CONCLUSIONS: Healthcare workers should be monitored in order to increase their compliance for infection control measures. Here, we emphasized that that CMAF of health workers may contribute reducing the HAI rate in the NICU.

RESUMEN

HBV reactivation (HBVr) is a well-known complication of immunosuppressive (IS) treatment. The aim of this study was to evaluate the awareness of rheumatologists about the risk of HBVr. A survey was sent via e-mail to 270 members of the Turkish Society for Rheumatology. It consisted of fourteen questions on their awareness of the major society guidelines, approach to hepatitis B virus (HBV) screening according to different IS regimens, decision process in screening patients for HBV, knowledge of antiviral treatments for HBV, follow-up strategies, experience and postgraduate training on HBVr. Forty-eight (17.8%) rheumatologists responded to the survey. Of the respondents, 93.8% reported that they screened all patients before IS treatment, while 6.2% screened patients with a high risk of HBV infection only. The screening rate was 95.8% (46/48) in patients undergoing high-risk IS treatment and 35.4% (17/48) in those undergoing low-risk treatment. All respondents screened for HBsAg, and 83.3% (40/48) screened for anti-HBc IgG and anti-HBs. Forty-four (91.7%) rheumatologists had previously initiated antiviral prophylaxis, and 14 (29.2%) had detected HBVr in at least one patient. Rheumatologists had a high awareness of the necessity for HBV screening before IS treatment. However, the screening rates were still lower than desired, especially in patients receiving IS treatments with moderate or low risk of reactivation.
