    Objectives: This study aims to determine the frequency and risk factors of bacteriuria and urinary tract infection (UTI) in patients with primary Sjogren's syndrome (SS) and their differences from healthy individuals and rheumatoid arthritis (RA) patients. Patients and methods: The study included 107 female primary SS patients (mean age 50.7 +/- 11.6 years; range, 23 to 76 years), 53 healthy female control subjects (mean age 46.8 +/- 15.5 years; range 21 to 80 years), and 40 females with RA (mean age 51.7 +/- 14.2 years; range, 25 to 79 years). Participants were questioned for UTI risk factors and symptoms. Middle stream urine samples were taken and cultured. All participants were examined with urinary symptom questioning survey of American Urological Association (AUA-7). Results: The urine cultures were positive in 18 primary SS patients (16.8\%), eight RA patients (20\%), and two healthy controls (3.7\%). Escherichia coli, enterococci, Klebsiella, streptococci, and candida were detected in SS patients' cultures. Extended-spectrum beta-lactamase was positive in three cultures. Asymptomatic bacteriuria was not detected in any SS patient. The highest AUA-7 score was determined in SS group (p=0.031). Nineteen SS patients had vaginal dryness symptom and their AUA-7 scores were higher than the rest of the SS group. The risk of UTI development was not different between those who had or did not have vaginal dryness. Conclusion: Urinary tract infections are seen more often in SS patients rather than normal population, which may be caused by SS' urinary system effects. It is difficult to distinguish between asymptomatic bacteriuria and infection because of the underlying urinary symptoms. Clinicians must be careful in patients receiving immunosuppressive therapy due to the high frequency of UTIs

    Geleneksel algılayıcıların metaller ve anyonların tespit edilmesinde karşılaşılan yavaş tepki verme ve seçicilik problemlerinden dolayı yeni kolorimetrik kemosensörlerin geliştirilmesi son yıllarda önemli bir ilgi alanı olmuştur. Bu konudaki çalışmalar hedef yapılara karşı seçici ve hızlı yeni floresans kemosensörleri geliştirmeye odaklanmıştır. Hidroksit ve florür anyonları kimyasal özellik olarak birbirlerine çok benzerler ve bu iki anyonun bulunduğu çevre ve biyolojik sistemlerdeki önemlerinden dolayı bu sistemlerde hızlı ve kolay yöntemlerle belirlenmesi önemlidir. Su içerisinde bulunan hidroksit anyonu suyun pH değeri ile ilişkilidir, bu nedenle suda bulunan hidroksit anyonu miktarı suda yaşayan canlı organizmaları etkilemektedir. Florür anyonu ise tıbbi öneme sahip olup osteoporoz gibi kemik hastalıkları insan vücudunda bulunan florür anyonun eksikliğinden kaynaklanmaktadır. Schiff bazları, sentezlenmeleri kolay, sıcaklığa karşı dayanıklı ve geniş bir uygulama alanına sahip olduklarından floresans ve kolorimetrik kemosensörlerin temel yapısı olarak seçilmişlerdir. Bu bilgiler doğrultusunda hidroksit anyonu tayini için yeni bir seri sitiril temelli floresan Schiff bazı sentezi gerçekleştirilmiştir. Sentezlenen Schiff bazları hidroksit anyonu ile deprotonasyon üzerinden etkileşmekte ve trifloroasetik asit (TFA) ile tekrar protonlanabilmektedir. Sentezlenen bileşikler donör-π-akseptör sistemi içerdiği için bileşiklerin NLO (doğrusal olmayan optik) özellikleri de teorik olarak incelenmiş ve potansiyel NLO adayı olup olmadıkları da ortaya koyulmuştur. Kemosensörlerin çeşitli çözücüler içerisindeki fotofiziksel özellikleri, hidroksit anyonuna ve TFA’ya karşı duyarlılığı UV-GB absorpsiyon ve Floresans spektroskopi yöntemleriyle araştırılmıştır. Ayrıca, etkileşim sonucunda meydana gelen kolorimetrik ve florimetrik değişim hem çıplak gözle hem de UV-ışığı altında incelenmiştir. Bileşiklerin ısısal kararlılıkları TGA (Termal Gravimetrik Analiz) yöntemi ile belirlenmiştir. Bileşiklerin 280 oC yüksek sıcaklığa kadar kararlı oldukları ortaya koyulmuşturDevelopment of new colorimetric sensors that will be replacing the current slow and inefficient traditional sensors for detecting both metals and anions in general has been a significant interest in recent years. For this case, many studies have been focused in developing new fluorescence colorimetric sensor that has far better accuracy and speed in determining appropriate substrates. Hydroxide and fluoride are two important anions as they contribute in many environmental, biological and cynical aspects in living ecosystem. For instance, hydroxide concentration in a body of water directly corresponds to pH that affects living organism reside in it. The later has gained medical importance as fluoride concentration in human body is critical in determining diseases such as late osteoporosis. Schiff bases were chosen as the basis structure for fluorescence and colorimetric chemosensors because they are easy to synthesize, temperature-resistant and have a wide range of applications. In these regards, we have designed and synthesized a series of new TFA-reversible fluorescent Schiff bases that can detect hydroxide ion through deprotonation process in a brief and easy manner. Sensors sensitivity against hydroxide anion has been determined using UV-Vis Absorption and Fluorescence spectroscopy. Any physical change of sensors was observed through naked eyes and under illuminating UV-lamp. Because of donor-π-acceptor system found inside molecular structure, there is a good chance to come across non-linear optic nature for each compound, therefore theoretical studies in this regard has been conducted and the result were very promising. Furthermore, all compounds thermal stability was determined by TGA (Thermal Gravimetric Analysis) method and were found to be stable up to 280 oC

    Objective: To assess short-term outcomes after minimally invasive (laparoscopic, robot-assisted, and hybrid) pancreatoduodenectomy (MIPD) versus open pancreatoduodenectomy (OPD) among European centers. Background: Current evidence on MIPD is based on national registries or single expert centers. International, matched studies comparing outcomes for MIPD and OPD are lacking. Methods: Retrospective propensity score matched study comparing MIPD in 14 centers (7 countries) performing >= 10 MIPDs annually (2012-2017) versus OPD in 53 German/Dutch surgical registry centers performing >= 10 OPDs annually (2014-2017). Primary outcome was 30-day major morbidity (Clavien-Dindo >= 3). Results: Of 4220 patients, 729/730 MIPDs (412 laparoscopic, 184 robot-assisted, and 130 hybrid) were matched to 729 OPDs. Median annual case-volume was 19 MIPDs (interquartile range, IQR 13-22), including the first MIPDs performed in 10/14 centers, and 31 OPDs (IQR 21-38). Major morbidity (28\% vs 30\%,P= 0.526), mortality (4.0\% vs 3.3\%,P= 0.576), percutaneous drainage (12\% vs 12\%,P= 0.809), reoperation (11\% vs 13\%,P= 0.329), and hospital stay (mean 17 vs 17 days,P> 0.99) were comparable between MIPD and OPD. Grade-B/C postoperative pancreatic fistula (POPF) (23\% vs 13\%,P< 0.001) occurred more frequently after MIPD. Single-row pancreatojejunostomy was associated with POPF in MIPD (odds ratio, OR 2.95,P< 0.001), but not in OPD. Laparoscopic, robot-assisted, and hybrid MIPD had comparable major morbidity (27\% vs 27\% vs 35\%), POPF (24\% vs 19\% vs 25\%), and mortality (2.9\% vs 5.2\% vs 5.4\%), with a fewer conversions in robot-assisted- versus laparoscopic MIPD (5\% vs 26\%,P< 0.001). Conclusions: In the early experience of 14 European centers performing >= 10 MIPDs annually, no differences were found in major morbidity, mortality, and hospital stay between MIPD and OPD. The high rates of POPF and conversion, and the lack of superior outcomes (ie, hospital stay, morbidity) could indicate that more experience and higher annual MIPD volumes are needed

    The immune system plays a fundamental role in the response to neoadjuvant chemotherapy (NAC) of locally advanced breast cancer (LABC) patients. Patients with pathological complete response (pCR) after NAC have a higher survival rate. Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and lymphocyte-to-monocyte ratio (LMR) are peripheral blood indicators of inflammatory response. This investigates the correlation between NLR, PLR, LMR, and other clinicopathological features of breast cancer patients before receiving NAC and pCR. Data of LABC patients who underwent NAC between 2009 and 2018 were retrospectively reviewed. Each patient's peripheral complete blood count was recorded before starting NAC. The cut-off values for neutrophils, lymphocytes, monocytes, and platelets in the peripheral blood and NLR, PLR, and LMR were determined by receiver operating characteristic curve analyses. The records of 131 patients were analyzed and divided into two groups, pCR (+ve) and pCR (-ve), and their clinicopathological features and laboratory findings were compared. pCR was achieved in 23.6\% of patients. The cut-off values of neutrophils, lymphocytes, monocytes, and platelets at the time of diagnosis and NLR, PLR, and LMR were, respectively, 4150 mu L, 2000 mu L, 635 mu L, 271 x 10(3) mu L, 1.95, 119, and 3.35. The pCR rate was higher in patients with low neutrophil count, low NLR, and high lymphocyte count (P = .002, <.001, and .040, respectively). As per the findings of multivariate logistic regression analysis, the independent predictive factors of pCR were clinical tumor size T1 and T2, grade 3, ER negativity, and low NLR (P = .015, .001, .020, .022, and .001, respectively). While NLR was found to be an independent predictive factor of pCR in LABC patients receiving NAC, a similar result was not observed for PLR and LMR. NLR can be a useful biomarker for predicting the response of patients receiving NAC
