Fabrication of Gd2O3/PSF Membranes via Aqueous Phase Inversion Method

This study aimed to investigate the effect of Gadolinium oxide (Gd2O3) concentration (0.5%, 1%, and 2%) on the performance of polysulfone (PSF) membrane. The membranes were fabricated by a common phase inversion method. The performance of membranes was determined based on pure water flux, bovine serum albumin (BSA) permeation test. These fabricated membranes were characterized by FTIR and contact angle measurements. The highest BSA rejection was 53%. The optimum membrane (2 % wt Gd2O3 /17 % wt PSF) in this study was determined by PSF 17% which successfully exhibited 53% rejection with filtrate flux for about 8.7 L/m2.h at a pressure of 10 bar

Comparison of respiratory tract pathogens and antibiotic susceptibility profiles of patients diagnosed with COVID-19 with pre-COVID-19

Objective: It is aimed to compare the respiratory tract agents and antibiotic resistance rates in patients with a diagnosis of COVID-19 with the non-COVID-19 period. Material and Method: Patients diagnosed with bacterial respiratory tract infection between March 2019 and March 2021 were included in the study. Bacteria identification and antibiotic susceptibility were evaluated according to automated system and EUCAST standards. Results: Between March 2019-March 2020 (before the pandemic), the most common bacterium was Pseudomonas aeruginosa (P. aeruginosa) 280 (15.5%) second Acinetobacter baumannii (A. baumannii) in a total of 1797 patients hospitalized in the service and intensive care units, and the resistance rates were the same. Between March 2020 and 2021, a total of 1357 COVID -19 patients were found in clinical and intensive care units, and the most common reproducing agent was A. baumannii 168 (12.3%), the second P. aeruginosa 164, and resistance rates were found to invrease. Conclusion: The increase in the resistance rates of bacteria causing respiratory tract infection was remarkable. It was determined that P. aeruginosa and A. baumannii, which were the most common isolates before the pandemic and showed high resistance rates against all antibiotic groups, were the most common bacteria during the pandemic period

Bağlama Operasyonları Esnasında Kopan Halat Yaralanmalarının Bulanık Hata Ağacı Yöntemi ile Analizi

Pek çok sektörde olduğu gibi denizcilik sektöründe de ölümlere, yaralanmalara, çevre kirliliklerine veya maddi hasarlara sebep olan kazalar yaşanmaktadır. Denizcilik sektörünün omurgasını oluşturan gemi taşımacılığı operasyonları, yapılan işin doğası gereği ciddi riskler barındırmaktadır. Bu riskleri yok etmek ya da kabul edilebilir risk seviyelerine indirgeyebilmek için pek çok emniyet tedbiri uygulanıyor olmasına rağmen gemi operasyonlarında yaşanan kazaların sayısı oldukça fazladır. Gemi operasyonları ile ilgili yaşanmış kazalar ve kaza istatistik raporları incelendiğinde gemi bağlama operasyonlarında yaşanmış olan kaza oranının oldukça yüksek olduğu görülmektedir. Çalışma kapsamında, Hata Ağacı Analizi yöntemi ile tanker terminal operasyonları için kopan halat yaralanması riski ve buna sebep olan kök sebepler tespit edilmiş olup Bulanık Mantık yöntemi ile de sayısal analizi gerçekleştirilmiştir. Tanker terminal bağlama operasyonlarında görevli gemi ve sahil çalışanlarından oluşan uzman grubu görüşlerine dayandırılarak oluşturulan model ile kopan halat yaralanma kazası risk değerinin hesaplanması ve alınabilecek önlemlerle bu risk değerinin azaltılabileceğinin bilimsel bir yaklaşımla ortaya konması hedeflenmiştir

Polyclonal outbreak of bacteremia caused by Burkholderia cepacia in the intensive care unit

Aim: Burkholderia cepacia is a multidrug-resistant, opportunistic pathogen of humans and outbreaks of infection in hospitals have been described. In this study, we aimed to report an outbreak in patients without cystic fibrosis or chronic granulomatous disease involving different species of Burkholderia cepacia. Material and Methods: A small outbreak of nosocomial Burkholderia cepacia complex occurred in a 6-bed intensive care unit. We isolated Burkholderia cepacia from blood cultures of the patients admitted to our intensive care unit. All isolates from patients and the environment were identified by standard microbiological techniques and VITEK system. Antibiotic susceptibility testing was performed using Kirby Bauer's disk diffusion method and the VITEK system Results: All isolates exhibited identical patterns of antibiotic susceptibility and all isolates were sensitive to trimethoprim-sulfamethoxazole, ceftazidime and meropenem. The isolates were typed using pulsed-field gel electrophoresis using the restriction enzymes XbaI and SpeI. Accordingly, while 4 strains were similar, one was different. Discussion: The experience from this outbreak reminded us of the importance of outbreak investigation in such small outbreaks and keeping the health care workers educated and constant attention on this issue. The results of this study emphasized once again the necessity to maintain our sensitivity to the basic principles of sanitation and to raise our awareness of such outbreaks

Radiation exposure in acute myeloid leukaemia, diffuse large B-cell lymphoma, and multiple myeloma patients in the first year following diagnosis

Purpose: Radiological examinations are critical in the evaluation of patients with haematological malignancies for diagnosis and treatment. Any dose of radiation has been shown in studies to be harmful. In this regard, we assessed the radiation exposure of 3 types of haematological malignancies (diffuse large B-cell lymphoma [DLBCL], acute myeloid leukaemia [AML], and multiple myeloma [MM]) in our centre during the first year after diagnosis. Material and methods: In the first year after diagnosis we retrospectively reviewed the radiation exposure data of 3 types of haematological malignancies (DLBCL, AML, and MM). The total and median CED value (cumulative effective radiation dose in millisieverts [mSv]) of each patient was used. Each patient's total and median estimated CED value was calculated using a web-based calculator and recorded in millisieverts (mSv). Results: The total radiation doses in one year after diagnosis (CED value) were 46.54 ± 37.12 (median dose: 36.2) in the AML group; 63.00 ± 42.05 (median dose: 66.4) in the DLBCL group; and 28.04 ± 19.81 (median dose: 26.0) in the MM group (p = 0.0001). There was a significant difference between DLBCL and MM groups. Conclusions: In all 3 haematological malignancies, the radiation exposure was significant, especially in the DBLCL group, within the first year of diagnosis. It is critical to seek methods to reduce these dosage levels. In diagnostic radiology, reference values must be established to increase awareness and self-control and reduce patient radiation exposure. This paper is also the first to offer thorough details on the subject at hand, and we think it can serve as a guide for further investigation

Comparison of two pandemics: H1N1 and SARS-CoV-2

OBJECTIVE: We aimed to compare the clinical, epidemiological, and prognostic features of the H1N1 pandemic in 2009 and the severe acute respiratory syndrome coronavirus 2 pandemic in 2020. METHODS: This retrospective study involved subjects from seven centers that were admitted and found to be positive for H1N1 or COVID-19 real-time polymerase chain reaction test. RESULTS: A total of 143 patients with H1N1 and 309 patients with COVID-19 were involved in the study. H1N1 patients were younger than COVID-19 ones. While 58.7% of H1N1 patients were female, 57.9% of COVID-19 patients were male. Complaints of fever, cough, sputum, sore throat, myalgia, weakness, headache, and shortness of breath in H1N1 patients were statistically higher than in COVID-19 ones. The duration of symptoms until H1N1 patients were admitted to the hospital was shorter than that for COVID-19 patients. Leukopenia was more common in COVID-19 patients. C-reactive protein levels were higher in COVID-19 patients, while lactate dehydrogenase levels were higher in H1N1 ones. The mortality rate was also higher in H1N1 cases. CONCLUSIONS: The severe acute respiratory syndrome coronavirus 2 pandemic is a major public health problem that continues to affect the world with its high rate of contagion. In addition, no vaccines or a specific drug for the benefit of millions of people have been found yet. The H1N1 pandemic is an epidemic that affected the whole world about ten years ago and was prevented by the development of vaccines at a short period. Experience in the H1N1 pandemic may be the guide to prevent the COVID-19 pandemic from a worse end

Boundary-making around a “transgender ghetto” in a neighborhood: a case in Alsancak, Izmir (Turkey)

Book of proceedings: Annual AESOP Congress, Spaces of Dialog for Places of Dignity, Lisbon, 11-14th July, 2017This study inquires how a transgender community negotiates and re-identifies its living and working space against the socio-spatial boundaries drawn by urban planning decisions, media images and policing strategies. It develops as a case study in Alsancak, a central-city neighborhood in Izmir, known as "the tolerant city" in Turkey. Alsancak is notorious for housing a transgender community most of whom are sexworkers. In the "sexed city", the sexual codings of the urban spaces and the populations associated with them demonstrate the modern societies´ conflicts and contradictions (Knopp, 1995). This study assumes that social identities and differences are established through constantly negotiated power relations, at which space plays a major role. Identities have spatial dimensions which are "constructed together and constructed through interaction" (Massey, 1994). Urban planning, policing strategies and media images are part of the dominant power relations that draw socio-spatial boundaries around marginalized groups as "others". However, boundary drawing is not only an act of control by the powerful but also an act of resistance by the weak (Pratt, 1999). Through their everyday practices, individuals and communities (here, transgenders) can produce, negotiate, and re-define such socio-spatial boundaries through social interaction, social conflict and social struggles. Despite the prevailing stigmatization, criminalization and policing of transgender people in Turkey, Alsancak neighborhood with its diverse socioeconomic, religious and ethnic groups, and commercial and service uses (with a vivid night-life) appears as a safe space for the transgender community. Transgender community lives and works in the inner streets of the neighborhood, which they call the "transgender ghetto". They experience significant social consequences ranging from discrimination to violence, even in this relative "safe space". Through archival research on urban planning decisions and media images about this transgender ghetto and in-depth interviews with local associations (including a LGBTI association), this study compares the socio-spatial acts of boundary drawing by the powerful and the weak. The findings of the study will be interpreted for developing urban planning decisions for an "inclusive city".Published versio

Patients Who Fainted Whilst Giving a Blood Sample in the Blood Collectıon Unit and a Stress Mediator: Cortisol

OBJECTIVE: Cortisol is a glucocorticoid and can be used as a stress mediator in association with adrenal insufficiency. A diagnosis of adrenal insufficiency is made when the episodically released cortisol levels are below 3 mcg/dl by making a single measurement at any time of the day. We aimed to determine the presence of underlying adrenal insufficiency by measuring cortisol levels in patients brought to the emergency room by the hospital code blue team that firstly performed their critical care, who fainted whilst giving blood samples in the blood collection unit. MATERIAL AND METHODS: Observational, prospective study; It consists of 28 patients brought to emergency department by Code Blue Team between 2017 and 2020. After physical examination and electrocardiogram(ECG) evaluation, samples were taken for complete blood count, biochemical parameters, venous blood gas, cardiac biomarkers and cortisol measurement. Obtained results were analyzed with SPSS 22. RESULTS: The lowest cortisol level was 9 mcg/dL, and the highest cortisol level was 40,4 mcg/dL. Cortisol levels were higher in women than men. But T-test analysis revealed that gender is not a determining factor in cortisol levels (p=0,26). The correlation between blood collection time and cortisol values was calculated close to zero (r2=0.09). The patient diagnosed with adrenal insufficiency with a single measurement was not defined in the study population. CONCLUSIONS: Patients with acute adrenal insufficiency may come to the emergency department with orthostatic hypotension, agitation, syncope, abdominal pain and fever, and may result in death if left untreated (1). Although emotional stress is 20% among the precipitating factors of adrenal crisis, no significant relationship was found between stress and cortisol in our study (2). The limitations of our study are that it can only be carried out during working hours, and advanced diagnostic tests can not be performed in the emergency room
