2019 Turkish Hypertension Consensus Report
(2019) Aydogdu, Sinan; Guler, Kerim; Bayram, Fahri; Altun, Bulent; Derici, Ulver; Abaci, Adnan; Tukek, Tufan; Sabuncu, Tevfik; Arici, Mustafa; Erdem, Yunus; Ozin, Bulent; Sahin, Ibrahim; Erturk, Sehsuvar; Bittigen, Atilla; Tokgozoglu, Lale; 31483311
The Turkish Hypertension Consensus Report was prepared for the first time in 2015 to adapt the European and American international guidelines to our clinical practice and to create a practical report that could be a basic reference for all physicians dealing with hypertensive patients. This report, which was prepared by a committee with representation from 5 leading hypertension associations, has been accepted and is widely used. New clinical studies in hypertension literature and updated international guidelines since 2015 have demanded an update of the Turkish Hypertension Consensus Report as well. In this updated 2019 report, blood pressure levels were classified as Normal, Elevated, Stage 1, and Stage 2 hypertension. A new section was added for secondary hypertension. It was specified that drug treatment may be initiated with any 1 or a combination of 4 groups of drugs (diuretics, calcium channel blockers, angiotensin-converting enzyme [ACE] inhibitors, and angiotensin receptor blockers [ARBs]), except a combination of an ACE inhibitor and an ARB. It was emphasized that beta-blockers may be a first choice for hypertension treatment in diseases such as atrial fibrillation, heart failure, and coronary artery disease. The initial recommendation for hypertension treatment is a combination therapy in patients with a blood pressure level >= 150/90 mmHg. Target blood pressure values were redefined according to age and the presence of comorbidities. The hypertension treatment algorithm was renewed; it is proposed that drug therapy can also be initiated with a risk-based approach for the group with an elevated blood pressure (systolic blood pressure: 120-139 mmHg, diastolic blood pressure: 80-89 mmHg). The threshold clinic systolic blood pressure level was reduced from 160 mmHg to >= 150 mmHg for the initiation of drug therapy in individuals 80 years of age or more. The section on the treatment of special groups has now been expanded to include pregnancy and lactation. As in the previous report, in this update, practical recommendations for the most common cases seen in the clinic were the goal, rather than a comprehensive report that addresses all aspects of hypertension. This report has evidence-based recommendations for most patients; however, it should be kept in mind that there may be differences from 1 patient to another and that physicians should take an individualized approach according to a good clinical evaluation.
A. Lazer ve Isik Sistemleri
(2020) Ozcan, Hamdi
Laser and light systems are being used and demanded by patients more and more everyday in the treatment of acne and scars. Various devices are used in active acne and scar treatment. The effects of light systems on acne and scar tissue have been reported in different magnitudes. Since there are differences in practice and methodology, no judgement can be made on the success of treatment methods. The effectiveness of light systems increases with combined therapies. Their use in combination with medical therapies may increase the rate of success.

Ageism During the Covid-19 Pandemic: Discussion and Recommendations
(2021) Madran, H. Andac Demirtas
The spread of the coronavirus disease 2019 (Covid-19) was labeled a "pandemic" by the World Health Organization on March 11, 2020. It has caused not only health-related issues but also economic, educational, psychological, and social problems. Further, discrimination associated with the pandemic has been observed around the globe. Besides the obvious negative consequences faced by the individuals targeted, pandemic-related discrimination has affected the spread of the virus by influencing public attitudes toward disease prevention and the restrictions imposed by authorities. Discrimination toward foreigners, minorities, and certain religious groups (e.g., Muslims) increased during this period. Additionally, the pandemic saw ageism spread rapidly to become more visible than ever. Acknowledging that Covid-19 poses a higher risk for individuals over a certain age, several countries implemented restrictions specific to those age groups. However, this practice resulted in the emergence of problems that were not considered initially, especially the escalation of ageism. This study examines ageism during the Covid-19 pandemic based on major theories and current research. First, discrimination and ageism are defined in detail. Then, pandemic-related ageism is discussed within the framework of basic theoretical approaches. Finally, recommendations for preventing ageism related to the pandemic and in general are presented.
Analysis of the effect of the number of criteria and alternatives on the ranking results in applications of the multi criteria decision making approaches in machining center selection problems
(2020) Ic, Yusuf Tansel; Yurdakul, Mustafa
Multi criteria machining center selection models are widely used in the literature. In the applications of multi-criteria decision making models, machining center selection criteria are directly taken from catalogues. It is known that to have a ranking model sensitive to the weights of the selection criteria, it is especially important to limit the number of selection criteria to 7 +/- 2. A similar proposal can be put forward for the number of machining centers. In this study, whether or not reducing the number of criteria and alternative machining centers make the ranking results more sensitive to the changes in the criteria weights is studied using Spearman's rank correlation test. The study results show that the ranking results become more sensitive with a reduced number of criteria and alternative machining centers.

Anti-Tumor Necrosis Factor Alpha Treatment and Tuberculin Skin Test
(2015) Bozkirli, Emine Duygu Ersozlu; Tufan, Muge Aydin; Ozisik, Lale; Sen, Nazan; Yucel, Ahmet Eftal
Purpose: The use of anti-tumor necrosis factor alpha (anti-TNF) drugs has been a milestone in the treatment of rheumatic diseases. Despite their strong efficacy, there are some factors restricting the use of anti-TNF agents. We must be careful especially for the granulomatous diseases which can be seen endemic in our country such as tuberculosis and leishmaniasis. In our country according to the RAED 2005 Consensus Meeting Reports, patients candidate for anti-TNF treatment are evaluated for both active and inactive tuberculosis before treatment and prophylaxis with isoniazid (INH) has been performed where indicated. Material and Methods: Tuberculin skin tests (TST) of 43 patients followed up in the Rheumatology Clinic and receiving anti-TNF therapy were repeated under treatment. Patients' pretreatment first TST results, drugs they used, INH prophylaxis state, smoking status and the duration of anti-TNF treatment were evaluated. Results: 14 patients (32.6%) were women, while 29 (67.4%) were men. The mean of first TST values were 11.72 +/- 90.3 mm (0-30) and the mean of second TST values were 12.06 +/- 12.4 mm (0-45). 48.8% of the patients were smoking and 74.4% of the patients had received INH prophylaxis for 9 months. The mean total duration of anti-TNF drug use was found as 22.67 +/- 19.11 (5-68) months. No statistically significant difference (p=0.888) was observed between the first pretreatment and second under treatment TST results of the patients. Discussion: Tuberculosis remains to be a serious public health problem for both our country and the whole world. For this reason in our country, a detailed assessment is performed for all patients before anti-TNF treatment. In our study patients who are planned to start anti-TNF therapy were assessed with their first TST values and INH prophylaxis were given to 32 patients (74.4%) before treatment. No statistically significant difference was observed between pre and post-treatment TST values when control TST were performed with the earliest after five months of treatment. These findings may suggest that there is no evident increase in the risk of tuberculosis for patients receiving anti-TNF treatment with appropriate INH prophylaxis.

(2016) Aliskan, Hikmet Eda; Colakoglu, Sule; Gocmen, Julide Sedef
Purpose: Streptococcus pneumoniae and Haemophilus influenzae are two of the major pathogens in respiratory infections, treatment is usually started empirically. The aim of this study was to detect in vitro resistance rates of S. pneumoniae and H. influenzae strains isolated from different lower respiratory clinical samples to the antibotics which are used for therapy of infections due to these pathogens. Material and Methods: Seventy seven S. pneumoniae and 117 H. influenzae strains, isolated from patients were included in the study. S. pneumoniae isolates which gave an inhibition zone diameter of > 20 mm for oxacillin were considered susceptible for penicilin. For the isolates which had an oxacillin zone diameter of <20 mm, MIC values of penicillin and cefotaxime were obtained by E-test method (bioMerieux, Marcy-l'Etoile, France). Results: Of 77 S. pneumoniae isolates, 24.6 % were resistant (MIC> 2 mg/l) and 31.1 % were intermediately resistant to parenteral penicillin. Resistance rates to antibiotics were as follows: erythromycin 40 %, trimethoprim/sulphametoxazole (TMP/SMX) 54.5 % and ofloxacin 6.4%. beta-lactamases were detected in 15.6% of the H. influenzae isolates by nitrocefin positivity. Conclusion: H. influenzae strains (8.6%) were identified as beta-lactamase negative ampicillin resistant (BLNAR) strains. Resistance rates for other antibiotics were as follows: ampicillin 28.6%, cefaclor 36.5%, cefuroxime 30.1%, clarithromycin 9.6%, cloramphenicol 7% and TMP-SMX 43.9%.

(2021) Gumus, Hatice Hale; Demiroglu, Yusuf Ziya; Aliskan, Hikmet Eda; Odemis, İlker; Ceylan, Ozgur; Pocan, Ahmet Gurhan; Karagum, Ozlem; 0000-0001-9060-3195; 0000-0003-2638-0163; 0000-0002-9866-2197; 0000-0003-2638-0163; 0000-0001-6910-7250; 0000-0003-0681-8375; 0000-0003-3128-1602; 0000-0001-9071-9606; 34416802; AAE-2282-2021; AFK-3690-2022; AAX-9250-2021; AAZ-9711-2021; AAG-2486-2022; AAK-8276-2021; U-4084-2017; AAE-6310-2021; AAJ-2108-2021
Globally 364102 healthcare professionals have been infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and 1253 of them died until 15 January 2021. Healthcare professionals serving at the forefront of combating the pandemic are in the high risk group. In our country, the data about coronavirus-2019 (COVID-19) among healthcare professionals are limited. The aim of this study was to investigate the anti-SARS-CoV-2 IgG seroprevalence in healthcare professionals, to evaluate the risks they encountered during work, and to examine their relationships with antibody positivity. A total of 572 healthcare professionals serving in various units of our hospital participated in our study and the presence of anti-nucleocapsid IgG was investigated by chemiluminescent microparticle immunoassay (SARS-CoV-2 IgG test, Abbott Laboratories Diagnostics, USA) method in serum samples collected between May 18, 2020 and June 30, 2020. The demographic characteristics, medical history, work conditions, medical procedures performed and possible risk factors were questioned with a questionnaire form. The average age of the participants was 33.5 +/- 9.2 (19-61) years, and 62.9% (360/572) of them were women. In our study, the anti-SARS-CoV-2 IgG seroprevalence was 3.7% (21/572). The association of the antibody positivity with age, gender and occupational status was not statistically significant (p> 0.05). Comorbid diseases which were significantly higher in seropositive healthcare professionals were hypertension (19%) and diabetes mellitus (14.3%) (p< 0.05). It was observed that antibody positivity was significantly higher in healthcare professionals working in high (52.4%) and medium risk (33.3%) areas, those who treat and/or examine patients with suspicious or positive COVID-19 (66.7%) and those who spend more than 30 minutes in COVID-19 patient rooms (76%) (p< 0.05). The symptoms associated with seropositivity in healthcare workers with a history of symptoms (46%) were loss of smell (23.5%), loss of taste (20.0%) and respiratory distress (16.7%) (p< 0.05). It was observed that the probability of being infected with SARS-CoV-2 increased 12 times if there was a colleague with COVID-19 in the hospital, four times if there was a patient in the house/lodging and six times if there was an infected person in the social environment (p< 0.05). The rate of those who had the flu vaccine among the participants was 10.8% (62/572) and 9.7% of them were found to be anti-SARS-CoV-2 IgG positive (p< 0.05, 95% CI= 1.31-9.48). The seropositivity was significantly higher in non-smokers (4.8 %) compared to smokers (0.0%) (p< 0.05). In our study, it was determined that the rate of seropositivity was 12 times higher in healthcare professionals who stated that they received hydroxychloroquine prophylaxis due to risky contact compared to those who did not receive prophylaxis (p< 0.05, 95% CI= 4.11-40.64). The ratio of the personnel who answered "always" to the frequency of wearing gloves, masks, goggles/face shields and overalls was 85.7%, 96.9%, 62.1% and 65.4%, respectively. In conclusion, regular and large-scale sero-epidemiological screening of healthcare professionals in the COVID-19 pandemic can contribute to the control of the pandemic by providing a better understanding of transmission dynamics and risk factors.
Application of spinal anesthesia in a pediatric patient with Duchenne's muscular dystrophy
(2016) Ozmete, Ozlem; Sener, Mesut; Caliskan, Esra; Aribogan, Anis; 27225742
Duchenne's muscular dystrophy (DMD) is a neuromuscular disease with a progressive course. It is the most common and most severe muscular dystrophic disorder for which the application of anesthesia is critical, due to muscle weakness, and cardiac and pulmonary involvement. Successful application of spinal anesthesia in a 2-year-old boy with DMD undergoing bilateral inguinal hernia repair is described in the present report. It is proposed that spinal anesthesia is an effective alternative to general anesthesia in certain pediatric patients, including those with DMD, for whom general anesthesia poses increased risk.
Are Bone Turnover Markers Related with Fracture Risk in Initial Diagnose Postmenopausal Osteoporosis? A Cross-Sectional Clinical Study
(2015) Yalbuzdag, Seniz Akcay; Sarifakioglu, Banu; Sengul, Ilker; Cetin, Nuri
Objective: In this study, we investigated the relationships between 10 year fracture risk calculated with FRAX assessment tool and bone turnover markers (BTM) in women with diagnosed as postmenopausal osteoporosis for the first time. Materials and Methods: After exclusion of the causes of secondary osteoporosis 61 postmenopausal women diagnosed with osteoporosis for the first time were enrolled. Height and weight measurements, comorbid diseases, menopause age, and laboratory investigations were recorded. Lumbar and femur neck and femur total T scores were measured by dual-energy x-ray absorptiometry (DXA). As BTM, serum osteocalcin (OC) and urine deoxypridinoline levels were measured. 10-year fracture risk of hip and major osteoporotic fracture was calculated with FRAX assessment tool. Results: The mean age of patients was 61 +/- 39 years. Median value of menopause year was 15.13 years (min: 2, max: 40). The median 10-year hip fracture and major osteoporotic fracture risks were calculated as 1.10% (min: 0, max: 23), 6.9% (min: 3, max: 34) respectively. There was no significant relationship between BTM and fracture risk. Positive significant correlation was found between menopause year and hip fracture risk, and between menopause year and major osteoporotic fracture risks (p=0.031, 0.276; p=0.025, r=0.287). Negative significant correlation was detected between body mass index and hip fracture risk (p=0.002, r=-0.392). Conclusion: In our study, we couldn't find relationship between BTM and fracture risks assessed by using FRAX tool in patients with initially diagnosed of postmenopausal osteoporosis. Further studies are needed to investigate the relationship between BTM and fracture risk in different patient groups.

(2017) Balkan, Arzu; Oner Erkekol, Ferda; Kokturk, Nurdan; Mungan, Dilsad; Sackesen, Cansin; Onen, Zeynep Pinar; Ozkan, Secil; Ergun, Pinar; Kocabas, Can Naci; Baran Aksakal, Nur; Ekici, Banu; Ozkan Altunay, Zubeyde; Gemicioglu, Bilun; Yorgancioglu, Arzu; 0000-0002-4032-0944; 28990886; AAC-7548-2020
Introduction: Chronic obstructive pulmonary diseases are common causes of disease in the community and account for considerable percent of the caseload in primary health care facilities. For this reason, it is important to question and improve the knowledge of primary health care physicians. This study is designed to assess the level of knowledge for bronchial asthma and COPD of the primary healthcare physicians, both before and immediately after an educational course structured in the context of GARD Chronic Airway Diseases National Control Program. Materials and Methods: The participating physicians attended an intensive educational course on asthma and COPD. Twenty five item questionnaires for asthma and COPD were administered to the participants both before and immediately after the end of the course. Contribution of education to the level of knowledge was investigated by comparing the percentages of the correct answers in the pre-and post-test. Results: From 11 different cities, 1817 and 1788 primary health care physician were attended to the asthma and COPD educations, respectively. The accuracy rate of >= 75% was obtained from only 4 questions in pre-test asthma questionnaire. On the contrary, in 15 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 45.8%, and this rate raised to 69.6% after education course. The accuracy rate of >= 75% could not be obtained from any of the questions in pre-test COPD questionnaire. On the contrary, in 19 questions the accuracy rate was < 50%. The mean accuracy rate for the whole asthma test was 42.0%, and this rate raised to 71.3% after education course. Conclusion: It has been shown that, in primary care settings, the level of knowledge in asthma and COPD should be enhanced and that this increase can be achieved with an education course.
B. Kimyasal Peeling
(2020) Ozcan, Hamdi
Although chemical peeling is used more widely for skin rejuvenation and aesthetic purposes, it is also used for the treatment of acne lesions and scars. Superficial peeling is used more for the treatment of active acne lesions, whereas medium and deep peeling for treating scars. Their side effects can be considerably reduced if used in a controlled and knowledgeable manner. In acne treatment, chemical peeling may be used in combination with medical therapies, surgical methods and even laser therapy, which can increase their overall efficacy.
Bilgisayar Programlama Derslerinde Öğrenme Motivasyonu Ölçeğinin Türkçe Uyarlaması: Geçerlilik ve Güvenilirlik Çalışması
(Başkent Üniversitesi Eğitim Bilimleri Fakültesi, 2018) Avcı, Ummuhan; Ersoy, Halil; 0000-0001-7007-1478; 0000-0003-1598-7656
Bu araştırmanın amacı Law, Lee ve Yu 2010 tarafından geliştirilen Bilgisayar Programlama Derslerinde Öğrenme Motivasyonu Ölçeği’ni Türkçe’ye uyarlamaktır. Bu amaçla geçerlik ve güvenirlik analizlerini yapmak üzere altı faktör bireysel tutum ve beklenti, zorlayıcı amaçlar, belirgin hedefler, ödül ve takdir, ceza, sosyal baskı ve rekabet ve 19 maddeden oluşan altılı Likert tipindeki ölçek, özel bir üniversitede okuyan 312 mühendislik fakültesi öğrencisine uygulanmıştır. Doğrulayıcı faktör analizi sonuçları incelendiğinde, ölçeğin altı faktörden oluştuğu doğrulanmış ve ölçeğin uyum iyiliği indislerinin yeterli düzeyde olduğu görülmüştür. Ölçeğin güvenilirliği Cronbach alfa iç tutarlılık katsayısı ile değerlendirilmiştir. Cronbach alfa katsayısının ölçeğin tamamında 0.90 olduğu ve faktörler bazında 0.71 ile 0.83 arasında değiştiği görülmüştür. Bu sonuçlar ölçeğin, bilgisayar programlama derslerinde öğrenme motivasyonunun ölçülmesinde geçerli ve güvenilir bir ölçme aracı olduğunu göstermektedir. The aim of this study is to adapt the Learning Motivation in Computer Programming Courses Scale developed by Law, Lee ve Yu 2010 to Turkish. In order to determine its validity and reliability, the scale consisting of 19 six-point Likert-type items within six factors individual attitude and expectation, challenging goals, clear direction, reward and recognition, punishment and social pressure and competition was applied to 312 engineering faculty students at a private university. When the results of the confirmatory factor analysis were examined, it was confirmed that the scale had six factors, and the goodness of fit indices are at an acceptable degree. The reliability of the scale was assessed by the Cronbach alpha internal consistency coefficient. The Cronbach’s alpha coefficiencies were found to be 0.90 for the whole scale and between 0.71 and 0.83 for the factors. These results show that scale is a valid and reliable measuring tool for learning motivation in computer programming courses
Biofilm Formation Research of Coagulase-Negative Staphylococci Isolates' Isolated from Blood and Hand Culture at Nanofilm Covered Micro Plaques by Plasma Polymerization Technique: An Experimental Model
(2017) Hortac Istar, Elvan; Gocmen, Julide Sedef; Cokeliler, Dilek; Mutlu, Mehmet; Kaleli Can, Gizem; Alparaslan, Sezin; Cetin, Ceren; Kartal, Naz; Ozcelik, Ugur Can; Aycan, Cagri; 0000-0002-4335-6897; 0000-0001-6423-7523; AAP-6138-2021
Introduction: Coagulase-negative staphylococci (CNS) can protect themselves from the effects of antibiotics by producing biofilms through breeding on biomaterials, medical equipment and devices. It is possible to influence biofilm formation with the aid of various surface modifications. In our study, plasma polymerization method, which is a surface modification technique, was used. The plasma polymerization technique is an environmentally-friendly technique that allows you to modify the nanometer level only at the surface without affecting the stack using the fourth state of the material. The possibility to generate surfaces with different properties (hydrophilic, hydrophobic, biocompatible etc.) by the help of various monomers and gases has made this technique more popular. In this study, the effect of the microplate surfaces modified by three different monomers on the biofilm formation of CNS was investigated. Materials and Methods: A total of 60 isolated CNS isolates from blood and hand cultures were included into the study. As control strains, Staphylococcus epidermidis ATCC 35984, known to be biofilm positive, and S. epidermidis ATCC 12228 which do not form biofilm, were used. Slime formation was determined by the quantitative plaque assay method described by Christensen. In microplates, which were plain or modified by three different monomers, the biofilm formation behavior of all strains was investigated simultaneously and comparatively. Results: There was no difference in biofilm positivity between strains isolated from hand and blood. A total of 71.6% biofilm formation was observed on microplates, which were not coated with plasma technique, and on plasma-modified microplated surfaces, 80% (monomer: 3- mercaptopropionic acid), 65% (monomer: 2-hydroxyethyl methacylate) and 31.6% (monomer: ethylene glycol dimethacylate) biofilm formation was observed, respectively. It was found that ethylene glycol dimethacrylate in three monomers significantly inhibited biofilm formation when compared to other monomers. Conclusion: In recent years CNS, especially S. epidermidis has become the most frequently isolated bacteria in catheter infections and responsible for the 28% of nosocomial bacteremia. The widespread use of prosthetic and permanent devices has been shown as a reason for the increase in the frequency of this effect. In 90% of patients with S. epidermidis bacteremia, there is an intravascular catheter history. Biofilm is an extracellular structure containing water, proteins and carbohydrates and is responsible for the unwanted adhesion of microorganisms to host cells and artificial surfaces. The biofilm mechanism can be altered by the interaction between the material surface and the bacterial surface. In our study, in-vitro results were obtained showing the potential to reduce the risk of biofilm-associated infection by microorganism biofilm formation on modified surfaces with appropriate monomer selection.
The Blockade of the Dardanelles Strait and the Occupation of Bozcaada During the Tripoli and Balkan Wars, Through the Eyes of Telegrapher Ihsan (Pere) Bey
(2022) Ozcan, Halil
Tripoli and Balkan Wars accelerated the process leading to the collapse of the Ottoman Empire. In these wars, the Dardanelles Strait and the islands near the strait were the common target chosen by Italy and Greece for the surrender of the Ottoman Empire. In both wars, Ihsan (Pere) Bey served as the telegraph officer of the British Eastern Cable Company in Bozcaada. The Tripoli War was continuing when Ihsan Bey, who had started his civil service as an officer of the Istanbul Beyoglu British Cable Company, was appointed as officer to Bozcaada for the second time. Ihsan Bey's witnessing in Bozcaada to the hot war of the Italian Navy and the Turkish Redoubts on April 18, 1912 and the detailed information he has given are important. In addition, the occupation of Bozcaada by Greece during the Balkan War is also included in detail in Ihsan Bey's memoirs. The originality of this study results from the fact that Ihsan Bey's memoirs when Italians reached to the entrance of the Dardanelles and regarding the occupation of Bozcaada are evaluated scientifically and published for the first time.
Bloodstream Infections: Etiologic Agents and Their Antibiotic Resistance Rates
(2016) Aydin, Mehtap; Kasikcioglu, Cemre; Nargiz-Kosucu, Sibel; Timurkaynak, Funda; Arslan, Hande; 0000-0002-5708-7915; ABG-7034-2021
Objective: In this study, we aimed to investigate the etiological agents of bloodstream infections (BSIs) and their antibiotic resistance rates. Methods: The rates of antibiotic resistance of the microorganisms isolated from blood cultures in the microbiology laboratory between 2012 and 2013 were evaluated retrospectively. Blood cultures were performed by using BACTEC (TM) 9120 (Becton Dickinson, Sparks, MD, USA) automated system. Microorganisms that were isolated were identified by routine microbiological methods. Results: In our study, BSIs were most frequently detected in the cardiovascular surgery clinic. Out of 95 bacteria isolated from blood culture, 61 (64.2) were Gram-negative bacteria (46% enteric, 18% nonfermentative), 20 (21%) were Candida spp. and 14 (15%) were Gram-positive bacteria. The most effective antibiotics for enteric bacteria were found as colistin, followed by imipenem, meropenem and amikacin and for nonfermentative Gram-negative bacteria as colistin, cefepime, piperacillin-tazobactam, imipenem and amikacin. Conclusions: When the resistance rates were compared within two years, significant increases in resistance were observed for quinolones and ceftazidime in nonfermentative bacteria, and for carbapenems in enteric bacteria. Regular monitoring of etiological agents of BSIs and their antibiotic resistance rates will guide the selection of empiric therapy.

Objective: Percutaneous vertebroplasty (PVP) is one of the frequently preferred interventional methods in spinal surgery. Although it is classified as minimally invasive, the most common complication of this procedure is bone cement leakage. Leakage of bone cement is often asymptomatic, but can lead to serious complications such as paraplegia and pulmonary embolism. In this study, we aimed to investigate the complications and consequences of cement leakage in the percutaneous vertebroplasty procedure. Methods: Between 2009 and 2015, 20 (14 female and 6 male, mean age 69.7) patients who underwent percutaneous vertebroplasty to 26 vertebrae were included in the study. 17 vertebrae were treated for osteoporotic compression (65.3%), 4 vertebrae for pathologic compression fractures (15.3%), 4 vertebrae for traumatic compression fractures (15.3%) and 1 vertebrae for painful hemangioma (3.8%). Leakage localizations of bone cement were classified as venous plexus, paravertebral soft tissue, spinal canal, intervertebral foramen, into the niddle channel and intervertebral disc space. Results: Twelve vertebrae showed no leakage (46.1%). 5 vertebrae had leakage into the niddle channel (19.2%), and 3 had leakage to vertebra disc space leakage (11.5%) and 2 vertebrae had to venous plexus and paravertebral tissue leakage (7.6%) Foraminal and spinal canal leakage (3.8%) was observed in one patient on single level. Radicular pain was seen in one patient. Partial pain control was observed in 20% of the patients while 80% of the patients had complete pain control on follow ups. Conclusion: Major complications following percutaneous vertebroplasty are mostly due to bone cement leaks. In order to prevent major complications, it is necessary to determine the possible causes of leakage. Performing the application with the correct technique with properly prepared bone cement is essential. Also usage of contast dye may be useful for pre-injection risk of leakage complications.
Can Digital Game Play Improve Older Adults' Cognitive Skills?
(2021) Secer, Ilmiye
Cognitive skills are essential for the performance of basic and instrumental daily living activities such as self-care, medication, and finance management. A decline in cognitive abilities with increasing age thus hinders older adults' ability to remain independent in society and negatively influences their quality of life. Therefore, many studies have investigated ways that can maintain and effectively improve such skills. Digital games have become a favored leisure activity by all age groups and are played for entertainment and stress relief. In this context, the ease with which digital games can be played within the home and their entertaining nature have led researchers to examine their effectiveness in enhancing older adults' cognitive skills. Although the findings indicate cognitive advantages, such as improved reaction times, working memory, and task-switching abilities, many questions require further clarification before claiming that digital game play is an effective cognitive training regime. Therefore, the current review aims to examine the cognitive advantages of digital games for older adults and suggests future research directions. The following topics need to be further explored: the existence of far transfer effects, that is, whether such improvements lead to better performance of daily activities, the long-term maintenance of enhanced skills and the underlying responsible mechanisms, the ecological validity of digital games, and digital games' provision of benefits beyond cognitive simulations. Furthermore, the importance to consider placebo effects, which was suggested by Boot, Blakely, and Simons (2011) and Boot, Simons, Stothart, and Stutts (2013), is emphasized.
