Lupus nephritis presenting with massive ascites and pleural effusion (pseudo-pseudo Meigs’ syndrome)

The triad of ascites, pleural effusion, and elevated cancer antigen-125 (CA-125) levels in the absence of ovarian malignancy in systemic lupus erythematosus patients is specifically named pseudo-pseudo Meigs’ syndrome (PPMS) or Tjalma syndrome. In this case we reported a 33 years female patient with pleural effusion lasting for 3 years and new onset progressive massive ascites and increased level of CA-125. After she was evaluated for an underlying benign and malign ovarian tumor or any other malignancies, serologic tests were requested with respect to progressive renal dysfunction, proteinuria, lymphopenia, anemia, and effusion.She was diagnosed with systemic lupus erythamatosus (SLE) and renal biopsy showed class-V lupus nephritis. Immunosuppressive treatment led to improvement in both SLE activity and components of PPMS, including massive ascites and pleural effusion and without the need of diuretics. Co-existence of unexplained CA-125 increase, pleural effusion, and ascites might be related to PPMS and detailed examination to exclude malignancy and early and effective treatment of SLE are the mainstay of management.

Clinical determinants of the modified incremental step test in adults with non-cystic fibrosis bronchiectasis / Determinantes clínicos do teste do degrau incremental modificado em adultos com bronquiectasia não fibrocística

ABSTRACT Objectives: This study primarily aimed to investigate the clinical determinants of the Modified Incremental Step Test (MIST) in adults with non-cystic fibrosis bronchiectasis (NCFB). A secondary objective was to compare the cardiopulmonary responses after the MIST and Incremental Shuttle Walk Test (ISWT), two commonly adopted symptom-limited maximum field tests in chronic respiratory diseases. Methods: Forty-six patients with clinically stable bronchiectasis participated in this cross-sectional study. MIST and ISWT were performed to determine exercise capacity, while disease severity, fatigue, and quality of life were assessed using the Bronchiectasis Severity Index (BSI), the Fatigue Severity Scale (FSS), and St. George's Respiratory Questionnaire (SGRQ), respectively. Quadriceps muscle strength was evaluated using a hand-held dynamometer, walking speed with a wireless inertial sensing device, and the level of physical activity (steps/day) with a pedometer. Results: The BSI score, quadriceps muscle strength, daily step count, and the SGRQ total score explained 61.9% of the variance in the MIST (p < 0.001, R2 = 0.67, AR2 = 0.619). The BSI score (r = -0.412, p = 0.004), quadriceps muscle strength (r = 0.574, p = 0.001), daily step count (r = 0.523, p < 0.001), walking speed (r = 0.402, p = 0.006), FSS score (r = -0.551, p < 0.001), and SGRQ total score (r = -0.570, p < 0.001) correlated with the MIST. The patients achieved higher heart rates (HR), HR%, desaturation, dyspnea, and leg fatigue in the MIST compared to the ISWT (p < 0.05). Conclusions: Disease severity, quadriceps muscle strength, physical activity level, and quality of life were determinants of MIST. The advantages of the MIST, including higher cardiopulmonary response than ISWT and greater portability, which facilitates its use in various settings, make MIST the preferred choice for investigating symptom-limited exercise capacity in patients with NCFB.

RESUMO Objetivos: Este estudo teve como objetivo principal investigar os determinantes clínicos do Teste do Degrau Incremental Modificado (TDIM) em adultos com bronquiectasia não fibrocística (BNFC). Um objetivo secundário foi comparar as respostas cardiopulmonares após o TDIM e o Teste Graduado de Caminhada (TGC), dois testes de campo máximos amplamente adotados e limitados por sintomas em doenças respiratórias crônicas. Métodos: Quarenta e seis pacientes com bronquiectasia clinicamente estável participaram deste estudo transversal. O TDIM e TGC foram realizados para determinar a capacidade de exercício, enquanto a gravidade da doença, fadiga e qualidade de vida foram avaliadas usando o Índice de Gravidade da Bronquiectasia (BSI), a Escala de Gravidade da Fadiga (FSS) e o Questionário Respiratório de Saint George (SGRQ), respectivamente. A força muscular do quadríceps foi avaliada usando um dinamômetro manual, a velocidade de caminhada com um dispositivo de sensor inercial sem fio e o nível de atividade física (passos/dia) com um pedômetro. Resultados: O escore BSI, a força muscular do quadríceps, a contagem diária de passos e o escore total do SGRQ explicaram 61,9% da variação no TDIM (p < 0,001, R2 = 0,67, AR2 = 0,619). O escore BSI (r = -0,412, p = 0,004), a força muscular do quadríceps (r = 0,574, p = 0,001), a contagem diária de passos (r = 0,523, p < 0,001), a velocidade de caminhada (r = 0,402, p = 0,006), o escore FSS (r = -0,551, p < 0,001) e o escore total do SGRQ (r = -0,570, p < 0,001) correlacionaram-se com o TDIM. Os pacientes atingiram maiores frequências cardíacas (FC), FC%, dessaturação, dispneia e fadiga nas pernas no TDIM em comparação com o TGC (p < 0,05). Conclusões: A gravidade da doença, a força muscular do quadríceps, o nível de atividade física e a qualidade de vida foram determinantes do TDIM. As vantagens do TDIM, incluindo uma resposta cardiopulmonar mais elevada que no TGC e maior portabilidade, que facilita sua utilização em diversos ambientes, fazem do TDIM a escolha preferencial para investigar a capacidade de exercício limitada por sintomas em pacientes com BNFC.

Fecal leukocyte frequency in children with acute viral gastroenteritis: a single-center experience

SUMMARY OBJECTIVE: Our objective was to determine the frequency of rotavirus, adenovirus, and rota-adenovirus co-infections and investigate the fecal leukocyte rate associated with these infections in patients with gastroenteritis. METHODS: This is a retrospective study. We identified patients who were admitted to the pediatric emergency department with acute gastroenteritis and had their stool samples tested for rotavirus and/or adenovirus antigens. Among them, we determined the individuals who underwent stool microscopy tests on the same day and recorded their results. RESULTS: A total of 1,577 patients who underwent testing for rotavirus and/or adenovirus antigens in their stool samples were identified. Among these patients, 583 individuals had concurrent fecal microscopy results. The prevalence of solely rotavirus antigen positivity was 16.4%, solely adenovirus antigen positivity was 2.9%, and rota-adenovirus co-infections were detected in 1.8% of the children. The fecal leukocyte rates in children infected with rotavirus, adenovirus, and rota-adenovirus co-infections were 4.8, 13.3, and 88.9%, respectively. CONCLUSION: The presence of fecal leukocytes was detected at a high rate in cases of viral gastroenteritis, especially in rota-adenovirus co-infections. Therefore, clinicians should not consider only bacterial pathogens in the presence of fecal leukocytes.

The potential applicability of facial nerve monitoring as a navigation tool in parotid gland surgery

Abstract Objectives: The aim of this study was to assess the relationship between the stimulation amplitude and the distance to the facial nerve. Methods: This study was designed as a prospective clinical study. A total of 20 patients (12 males, 8 females) were included. Partial superficial parotidectomy was performed in all patients with intraoperative facial monitoring. Measurements were made on the main trunk and major branches. Stimulation was started at 1 mA and incrementally increased to 2 and 3mA's. The shortest distance creating a robust response (>100mV) was recorded. Results: At 1 mA, 2 mA and 3 mA stimulation intensity, the average distance between the tip of the stimulation probe and the main trunk was 2.20±0.76 mm (range 1-3 mm), 3.80±0.95 mm (range 2-5 mm), 4.80±1.05 mm (range 3-7 mm) respectively. The stimulus intensity was inversely proportional in respect to the distance between the nerve and the tip of the stimulus probe (P < .00). The same relation was present in the facial nerve major branch measurements (P < .00). Conclusion: The proportional stimulation amplitude and distance to the facial nerve is thought to be a reliable auxillary method to assist the surgeon by facilitating the estimation of the distance to the facial nerve during extracapsular dissection and minimally invasive cases where the facial nerve isn't routinely dissected. Level of evidence: Level 3.

Protective effect of creatine on amikacin-induced ototoxicity / Efeito protetor da creatina na ototoxicidade induzida por amicacina

Abstract Introduction Aminoglycosides are widely known for their ototoxic side effects. Nevertheless, they are potent antibiotics used in the treatment of life-threatening conditions because of the current concern for antibiotic resistance. We hypothesized that creatine supplements which are believed to improve mitochondrial antioxidant defense system and maintain optimal energy homeostasis may improve the ototoxic side effects. Objective This study aimed to investigate the protective effects of creatine monohydrate against ototoxicity induced by amikacin in rats in an experimental animal model, using distortion product otoacoustic emissions and auditory brainstem response. Methods Twenty healthy rats were assigned to four groups (5 rats in each): the control group, the creatine monohydrate group, the amikacin group and the amikacin + creatine monohydrate group. The creatine monohydrate group received creatine at a dose of 2 g/kg once daily via gastric gavage for 21 days. The amikacin group received amikacin at a dose of 600 mg/kg by intramuscular injections once daily for 21 days. The amikacin + creatine monohydrate group received intramuscular injections of amikacin (600 mg/kg) once daily for 21 days and creatine monohydrate (2 g/kg) once daily via gastric gavage for 21 days. The control group received nothing. The distortion product otoacoustic emissions and auditory brainstem response measurements were performed on all rats on days 0, 7, 21. Results Regarding auditory brainstem response values, a significant increase in the auditory threshold was observed in the amikacin group on day 21 (p < 0.001). The amikacin+creatine monohydrate group showed significantly lower levels of auditory brainstem response auditory thresholds on day 21 in comparison to the amikacin group (p < 0.001). Additionally, the control group and the amikacin+creatine monohydrate group did not differ significantly with respect to auditory brainstem response thresholds on treatment day 21 (p > 0.05). When we compare distortion product otoacoustic emissions values, there was no significant difference between the amikacin and amikacin+creatine monohydrate groups on day 7 (p > 0.05), However significantly greater distortion product otoacoustic emissions values were observed in the amikacin+creatine monohydrate group on day 21 compared to the amikacin group (p < 0.001). Conclusion Our findings demonstrate that creatine treatment protects against amikacin ototoxicity when given at a sufficient dose and for an adequate time period.

Resumo Introdução Os aminoglicosídeos são amplamente conhecidos por seus efeitos colaterais ototóxicos. No entanto, eles são antibióticos potentes usados no tratamento de doenças potencialmente fatais devido à atual preocupação com a resistência aos antimicrobianos. Nossa hipótese é que os suplementos de creatina, aos quais atribui-se um efeito benéfico sobre o sistema de defesa antioxidante mitocondrial e manutenção da homeostase energética ideal, possam melhorar os efeitos colaterais ototóxicos. Objetivo Investigar os efeitos protetores da creatina mono-hidratada contra a ototoxicidade induzida pela amicacina em ratos em um modelo experimental animal com o uso das emissões otoacústicas por produto de distorção e o potencial evocado auditivo de tronco encefálico. Método Vinte ratos saudáveis foram divididos em quatro grupos (5 ratos em cada): o grupo controle, o grupo creatina mono-hidratada, o grupo amicacina e o grupo amicacina + creatina mono-hidratada. O grupo creatina mono-hidratada recebeu creatina na dose de 2 g / kg uma vez ao dia por gavagem gástrica por 21 dias. O grupo amicacina recebeu amicacina na dose de 600 mg/kg por injeção intramuscular uma vez ao dia por 21 dias. O grupo amicacina + creatina mono-hidratada recebeu injeções intramusculares de amicacina (600 mg/kg) uma vez ao dia por 21 dias e creatina mono-hidratada (2 g/kg) uma vez ao dia por gavagem gástrica por 21 dias. O grupo controle nada recebeu. As medidas de emissões otoacústicas por produto de distorção e potencial evocado auditivo de tronco encefálico foram feitas em todos os ratos nos dias 0, 7, e 21. Resultados Em relação aos valores do potencial evocado auditivo de tronco encefálico, foi observado aumento significante dos limiares auditivos no grupo amicacina no 21° dia (p < 0,001). O grupo amicacina + creatina mono-hidratada apresentou níveis significantemente mais baixos de limiares auditivos de potencial evocado auditivo de tronco encefálico no dia 21 em comparação com o grupo amicacina (p < 0,001). Além disso, o grupo controle e o grupo amicacina + creatina mono-hidratada não diferiram significantemente em relação aos limiares de potencial evocado auditivo de tronco encefálico no 21° dia de tratamento (p > 0,05). Quando comparamos os valores de emissões otoacústicas por produto de distorção, não houve diferença significante entre os grupos amicacina e amicacina + creatina mono-hidratada no 7° dia (p > 0,05). No entanto, valores significantemente mais altos de emissões otoacústicas por produto de distorção foram observados no grupo amicacina + creatina mono-hidratada no 21° dia em comparação com o grupo amicacina p < 0,001). Conclusão O tratamento com creatina mono-hidratada protege contra a ototoxicidade da amicacina quando administrado em dose suficiente e por um período de tempo adequado.

Biomarker potential of hsa-miR-145-5p in peripheral whole blood of manic bipolar I patients

Objective: Bipolar I disorder (BD-I) is a type of bipolar spectrum disorder characterized by manic or mixed episodes. Detecting microRNA regulations as epigenetic actors in BD-I is important to elucidate the pathogenesis of the disease and reveal the potential of microRNAs (miRNAs) as biomarkers. Methods: We evaluated the expression profile of six candidate miRNAs (hsa-miR-145-5p, hsa-miR-376a-3p, hsa-miR-3680-5p, hsa-miR-4253-5p, hsa-miR-4482-3p, and hsa-miR-4725) in patients with BD-I and in healthy controls (aged 11-50 years). We also determined the potential target genes of these miRNAs through in silico analysis. The diagnostic values of the miRNAs were calculated through receiver operating characteristic curve analysis. Results: Four miRNAs were upregulated (hsa-miR-376a-3p, hsa-miR-3680-5p, hsa-miR-4253-5p, hsa-miR-4482-3p) and hsa-miR-145-5p was downregulated in patients (p < 0.001). The target gene analyses showed that hsa-miR-145-5p specifically targets the dopamine decarboxylase (DDC) gene. The area under the curve of hsa-miR-145-5p was 0.987. Conclusion: Differential expression of five miRNAs in peripheral blood may be associated with the pathogenesis of BD-I, and hsa-miR-145-5p has potential as a BD-I biomarker. This miRNA can be used in dopamine-serotonin regulation and dose adjustment in drug therapy via the DDC gene.

Short-term effects of fibrinolytic therapy on the hemodynamic parameters of patients with intermediate- and high-risk pulmonary embolism

Objective@#We aimed to determine the effect of fibrinolytic therapy on hemodynamic parameters at 4 hours after treatment and bleeding complications in patients with intermediate- and high-risk pulmonary embolism. @*Methods@#This single-center, retrospective, cohort study included patients with intermediate- and high-risk pulmonary embolism treated with fibrinolytics. Their demographic and clinical characteristics, complications, and vital signs at the initiation of and 4 hours after fibrinolytic therapy were evaluated. The primary outcome was the change in the patients’ vital signs at 4 hours after fibrinolytic therapy, compared by the Mann-Whitney U-test. @*Results@#Seventy-nine patients were included in this study. The systolic and diastolic blood pressures of the high-risk group at 4 hours after fibrinolytic therapy were higher than those at the initiation of fibrinolytic therapy (80 mmHg vs. 99 mmHg, P = 0.029; 49 mmHg vs. 67 mmHg, P = 0.011, respectively). In the intermediate-risk group, the oxygen saturation increased (94% vs. 96%, P = 0.004) and pulse rate decreased (104 beats/min vs. 91 beats/min, P < 0.001). @*Conclusion@#Blood pressure at 4 hours after fibrinolytic therapy increased in patients with high-risk pulmonary embolism. Also, oxygen saturation and pulse rate improved in intermediate-risk patients.

Synthesis and characterization of chitosan-PVA hydrogel containing PEGylated recombinant epidermal growth factor on cell culture for wound healing substitute

Abstract The aim of the current study was to assess the physicochemical characteristics and wound healing activity of chitosan-polyvinyl alcohol (PVA) crosslinked hydrogel containing recombinant human epidermal growth factor (rh-EGF) or recombinant mouse epidermal growth factor (rm-EGF). The hydrogels were prepared and analyses were made of the morphological properties, viscosity, water absorption capacity, mechanical and bio-adhesive properties. The viscosity of the formulations varied between 14.400 - 48.500 cPs, with the greatest viscosity values determined in K2 formulation. F2 formulation showed the highest water absorption capacity. According to the studies of the mechanical properties, H2 formulation (0.153±0.018 N.mm) showed the greatest adhesiveness and E2 (0.245±0.001 mj/cm2) formulation, the highest bio-adhesion values. Hydrogels were cytocompatible considering in vitro cell viability values of over 76% on human keratinocyte cells (HaCaT, CVCL-0038) and of over 84% on human fibroblast cells (NIH 3T3, CRL-1658) used as a model cell line. According to the BrdU cell proliferation results, B1 (197.82±2.48%) formulation showed the greatest NIH 3T3 and C1 (167.43±5.89%) formulation exhibited the highest HaCaT cell proliferation ability. In addition, the scratch closure assay was performed to assess the wound healing efficiency of formulation and the results obtained in the study showed that F2 formulation including PEGylated rh-EGF had a highly effective role.

Evaluation of subclinical atherosclerosis by ultrasound radiofrequency data technology in patients with psoriatic arthritis

SUMMARY OBJECTIVE: This study aimed to assess the presence of subclinical atherosclerosis in patients with psoriatic arthritis using ultrasound radiofrequency data technology. METHODS: In all, 29 psoriatic arthritis patients and 42 age- and sex-matched healthy controls were included in this cross-sectional study. Arterial stiffness and carotid intima-media thickness measurements were performed in bilateral common carotid arteries using ultrasound radiofrequency data technology in all participants. RESULTS: In psoriatic arthritis patients, the mean carotid intima-media thickness, α and β stiffness indices, and pulsed wave velocity value were significantly higher than those in the control group (542.3 (81.3) vs. 487.9 (64.1), 9.3 (6.3) vs. 3.9 (0.1), 18.7 (17.7) vs. 8.04 (4.2), and 10.2 (3.8) vs. 6.4 (1.5), p<0.05). The mean distensibility coefficient and compliance coefficient values of the patient group were significantly lower than those of the control group (0.014 (0.01) vs. 0.03 (0.01) and 0.57 (0.33) vs. 1.02 (0.4), p<0.05). No significant correlation was found between carotid artery hemodynamic parameters and symptom duration, duration of diagnosis and treatment, disease activity ındex for psoriatic arthritis scores, erythrocyte sedimentation rate, and C-reactive protein levels (p>0.05). CONCLUSION: In the results of our study, evidence of subclinical atherosclerosis has been detected in psoriatic arthritis patients without clinically evident cardiovascular disease or traditional cardiovascular risk factors.

Is pectoralis muscle index a risk factor for mortality in left ventricular assist device patients?

SUMMARY OBJECTIVE: We aimed to investigate whether sarcopenia measured from pectoralis muscles is a risk factor for long-term mortality in left ventricular assist device patients. METHODS: Patients aged >18 years implanted with a left ventricular assist device in a single center between 2013 and 2019 were retrospectively included. Patients without a thoracic computed tomography scan performed within 3 months of left ventricular assist device implantation and without computed tomography scans appropriate for pectoralis muscle measurement were excluded. Pectoralis muscle measurements were made on thoracic computed tomography slices, and pectoralis muscle indices were calculated for each patient. Sarcopenia was defined as being in the gender-specific lowest tertile of pectoralis muscle index. Survival was compared between patients with and without sarcopenia. RESULTS: The study was conducted on 64 left ventricular assist device patients who met the inclusion criteria. Notably, 21 (32.8%) of the study patients were sarcopenic. Diabetes mellitus and sarcopenia were more common in patients with 2-year mortality in our cohort. Patients with sarcopenia had a worse 2-year survival (p<0.001). Sarcopenia had an adjusted hazard ratio of 4.04 (95% confidence interval (CI) 1.36-12.02, p=0.012), while diabetes mellitus was associated with an adjusted hazard ratio of 3.14 (95%CI 1.17-8.39, p=0.023). CONCLUSION: Sarcopenia defined by low pectoralis muscle index increases the risk for 2-year mortality in left ventricular assist device patients.

Delayed chest closure for oversized lung allograft in lung transplantation: a retrospective analysis from turkey

Abstract Introduction: The aim of this study was to evaluate the delayed chest closure (DCC) results in patients who underwent lung transplantation. Methods: Sixty patients were evaluated retrospectively. Only bilateral lung transplantations and DCC for oversized lung allograft (OLA) were included in the study. Six patients who underwent single lung transplantation, four patients who underwent lobar transplantation, two patients who underwent retransplantation, and four patients who underwent DCC due to bleeding risk were excluded from the study. Forty-four patients were divided into groups as primary chest closure (PCC) (n=28) and DCC (n=16). Demographics, donor characteristics, and operative features and outcomes of the patients were compared. Results: The mean age was 44.5 years. There was no significant difference between the demographics of the groups (P>0.05). The donor/recipient predicted total lung capacity ratio was significantly higher in the DCC group than in the PCC group (1.06 vs. 0.96, P=0.008). Extubation time (4.3 vs. 3.1 days, P=0.002) and intensive care unit length of stay (7.6 vs. 5.2 days, P=0.016) were significantly higher in the DCC group than in the PCC group. In the DCC group, postoperative wound infection was significantly higher than in the PCC group (18.6% vs. 0%, P=0.19). Median survival was 14 months in all patients and there was no significant difference in survival between the groups (16 vs. 13 months, P=0.300). Conclusion: DCC is a safe and effective method for the management of OLA in lung transplantation.

Microbiological Spectrum of Nosocomial ECMO Infections in a Tertiary Care Center

Abstract Introduction: Extracorporeal membrane oxygenation (ECMO) is a life-saving treatment in cardiogenic and respiratory shock. It is prone to various complications, infection being among the most frequent. This study aims to define the prevalence and characteristics of infections in ECMO patients in a tertiary care center for cardiac diseases. Methods: All ECMO patients between 2012 and 2016 in a single cardiac center were retrospectively included. Demographic data, ECMO indications, type, site, duration, and infection-related data were recorded. Data were analyzed among all patients and separately between pediatric and adult patient groups. Results: One hundred and twenty-six patients, 66 (53.4%) pediatric and 60 (47.6%) adult, received ECMO within the study period. Mean age was 3.54±4.27 years in the pediatric group and 54.92±15.57 years in the adult group. The main indication for ECMO was postcardiotomy shock (77.8%). Forty-six (36.5%) of all cases developed a culture-proven nosocomial infection with a rate of 49/1000 ECMO days. Infection was associated with > 5 days of ECMO duration and hemodialysis requirement in all patients and lower age in the pediatric group. The most frequent infection site was the lower respiratory tract (14.3%), while the most common isolated organisms were Klebsiella (8.7%) and Streptococcus (4.8%) species. Conclusion: The respiratory tract is the most common site of infection, however, all sites impose a threat to recovery, with longer treatment durations required for patients with culture-proven infections. A better understanding of the infectious spectrum and its effect on the mortality and morbidity is required for more successful treatment of ECMO patients.

Social media use in patients with fibromyalgia and its effect on symptom severity and sleep quality

Abstract Background: The aim of this study was to evaluate social media use in patients with fibromyalgia syndrome (FMS) and determine the effect of social media use on disease severity and sleep quality. Materials and methods: In total, 205 social media using patients with similar characteristics were included in the study. The study group consisted of 103 patients with FMS, and the control group consisted of 102 patients without FMS. The FMS symptom severity scale and diffuse pain index were used to determine the disease severity in FMS patients, the sleep disorder short form questionnaire (PROMIS) was used to evaluate sleep quality, and the Social Media Addiction Scale-Adult Form was used to evaluate social media addiction. A visual analog scale was applied to evaluate pain in both the patient and control groups, and social media usage times were recorded. Results: We found that pain severity, sleep disturbance and social media addiction were higher in patients with FMS than in the control group, and there was no relationship between the rates of social media use in patients with FMS and the severity and prevalence of the disease. Conclusion: The use of social media is more frequent in patients with FMS, which can motivate healthcare professionals to evaluate social media habits in individuals with FMS.

Farmers' perception of agricultural cooperatives: the case of Şanlıurfa, Turkey / A percepção dos agricultores sobre as cooperativas agrícolas: o caso de Şanlıurfa, Turquia

ABSTRACT: Şanlıurfa is the province with the third-largest agricultural area in Turkey. However, it has only 0.62% of the total number of cooperatives in the country. This study aimed to determine the perceptionsof farmers in Şanlıurfa regarding agricultural cooperatives and the factors affecting them. The main research material was obtained through face-to-face surveys involving farmers in Şanlıurfa selected by a simple random sampling method. The sampling volume was determined with a 95% confidence limit and a 5% error margin. Multiple regression analysis was used in Stata software. According to the results of the research, 39.7% of the participants were cooperative members and more than half of them were not active members. Of the participants, 30.3% had a positive perception of cooperatives, 36.82% were undecided, and 32.88% had negative opinions. Age, marital status, non-agricultural income, experience, social security, farmer registration system, cooperative membership, and land variables positively affected farmers' perceptions. However, the variables of education, income, and union membership had negative effects on farmers' perceptions. No statistically significant relationship was reported between a farmer's perception and any of the following variables: the number of people that make up the farmer's household, the number of individuals engaged in agriculture and non-agricultural work in the family, and the status of the farmer's lease. Conceptual, local, cultural, educational, and structural problems related to cooperatives exist in Şanlıurfa.These issues need to be given more attention by the public. This research is the first study on this subject to be conducted in Şanlıurfa.

RESUMO: Şanlıurfa é a província com a terceira maior área agrícola da Turquia. No entanto, possui apenas 0,62% do número total de cooperativas no país. Este estudo teve como objetivo determinar as atitudes e a percepção dos agricultores em Şanlıurfa em relação às cooperativas agrícolas e os fatores que as afetam. O principal material de pesquisa foi obtido através de pesquisas presenciais envolvendo agricultores em Şanlıurfa, selecionados por um método simples de amostragem aleatória. O volume amostral foi determinado com um limite de confiança de 95% e uma margem de erro de 5%. A análise de regressão múltipla foi utilizada. De acordo com os resultados da pesquisa, 39,7% dos participantes eram cooperados e mais da metade deles não eram ativos. Dos participantes, 30,3% tinham percepção positiva das cooperativas, 36,82% estavam indecisos e 32,88% tinham opiniões negativas. Idade, estado civil, renda não agrícola, experiência, previdência social, sistema de registro de agricultores, participação em cooperativas e variáveis de terra afetaram positivamente as atitudes dos agricultores. No entanto, as variáveis educação, renda e filiação sindical tiveram efeitos negativos nas atitudes dos agricultores em relação às cooperativas. Não foi encontrada relação estatisticamente significante entre a percepção das cooperativas por parte de um agricultor e qualquer uma das seguintes variáveis: número de pessoas que compõem a família do agricultor, número de indivíduos envolvidos na agricultura e trabalho não agrícola na família e status de arrendamento do fazendeiro. Problemas conceituais, locais, culturais, educacionais e estruturais relacionados às cooperativas existem em Şanlıurfa. Esta pesquisa é o primeiro estudo sobre esse temarealizado em Şanlıurfa.

Acute prostatitis after prostate biopsy under ciprofloxacin prophylaxis with or without ornidazole and pre-biopsy enema: analysis of 3. 479 prostate biopsy cases

ABSTRACT Objectives: To investigate the characteristics of cases of NIH category I acute prostatitis developed after transrectal prostate biopsy and clarifiy the risk factors and preventive factors. Materials and Methods: We retrospectively reviewed the medical records of 3.479 cases of transrectal ultrasound-guided needle biopsies performed with different prophylactic antibiotherapy regimens at two different institutions between January 2011 and February 2016. The patients of Group I have received ciprofl oxacin (n=1.523, 500mg twice daily) and the patients of Group II have received ciprofl oxacin plus ornidazole (n=1.956, 500mg twice daily) and cleansing enema combination as prophylactic antibiotherapy. The incidence, clinical features and other related microbiological and clinical data, were evaluated. Results: Mean age was 62.38±7.30 (47-75), and the mean prostate volume was 43.17±15.20 (21-100) mL. Of the 3.479 patients, 39 (1.1%) developed acute prostatitis after the prostate biopsy procedure. Of the 39 cases of acute prostatitis, 28/3.042 occurred after the first biopsy and 11/437 occurred after repeat biopsy (p=0.038). In Group I, 22 of 1.523 (1.4%) patients developed acute prostatitis. In Group II, 17 of 1.959 (0.8%) patients developed acute prostatitis. There was no statistical difference between the two groups according to acute prostatitis rates (X2=2.56, P=0.11). Further, hypertension or DM were not related to the development of acute prostatitis (P=0.76, X2=0.096 and P=0.83, X2=0.046, respectively). Conclusions: Repeat biopsy seems to increase the risk of acute prostatitis, while the use of antibiotics effective for anaerobic pathogens seems not to be essential yet.

A micro-computed tomography evaluation of voids using calcium silicate-based materials in teeth with simulated internal root resorption

OBJECTIVES: The obturation quality of MTA, Biodentine, Total Fill BC root canal sealer (RCS), and warm gutta-percha (WGP) in teeth with simulated internal root resorption (IRR) was evaluated by using micro-computed tomography.MATERIALS AND METHODS: Standardized IRR cavities were created using 40 extracted maxillary central incisor teeth and randomly assigned into 4 groups (n = 10). IRR cavities were filled with MTA, Biodentine, Total Fill BC RCS (bulk-fill form) and WGP + Total Fill BC RCS. Percentage of voids between resorptive cavity walls and obturation material (external void), and inside the filling materials (internal voids) were measured.RESULTS: Total Fill BC sealer in the bulk-fill form presented significantly highest values of external and internal void percentages (p < 0.05). Biodentine showed a significantly lowest external void percentage (p < 0.05). WGP + Total Fill BC RCS presented significantly lower values of internal void percentages than all groups (p < 0.05), except Biodentine (p > 0.05).CONCLUSION: None of the filling materials were created void-free obturation in resorption cavities. Biodentine may favor its application in teeth with IRR over Angelus MTA and bulk-fill form of Total Fill BC.

Unexpectedly High Prevalence of Low Alpha-Galactosidase A Enzyme Activity in Patients with Focal Segmental Glomerulosclerosis

OBJECTIVES: Fabry disease (FD) is a rare disease associated with sphingolipid accumulation. Sphingolipids are components of plasma membranes that are important in podocyte function and accumulate in various glomerular diseases such as focal segmental glomerulosclerosis (FSGS). Both FD and FSGS can cause podocyte damage and are classified as podocytopathies. In this respect, FD and FSGS share the same pathophysiologic pathways. Previous screening studies have shown that a significant proportion of end-stage renal disease (ESRD) patients receiving hemodialysis (HD) have unsuspected FD, and the prevalence of low alpha-galactosidase A (αGLA) enzyme activity in these patients is higher than that in the normal population. We aimed to compare αGLA enzyme activity in patients with biopsy-proven FSGS and ESRD receiving HD. METHODS: The records of 232 patients [62 FSGS (F/M: 33/29); 170 HD (M/F: 93/79)] were evaluated retrospectively. The screening was performed based on the αGLA enzyme activity on a dried blood spot, with the confirmation of plasma LysoGb3 levels, and the known GLA mutations were tested in patients with low enzyme activities. The two groups were compared using these parameters. RESULTS: The mean level of αGLA enzyme activity was found to be lower in FSGS patients than in the HD group (2.88±1.2 μmol/L/h versus 3.79±1.9 μmol/L/h, p<0.001). There was no significant relationship between the two groups with regard to the plasma LysoGb3 levels (2.2±1.22 ng/ml versus 1.7±0.66 ng/ml, p: 0.4). In the analysis of GLA mutations, a D313Y mutation [C(937G>T) in exon p] was found in one patient from the FSGS group. CONCLUSIONS: We found that αGAL activity in patients with FSGS is lower than that in patients undergoing HD. The low enzyme activity in patients with FSGS may be explained by considering the similar pathogenesis of FSGS and FD, which may also lead to sphingolipid deposition and podocyte injury.

Pentraxin-2 is associated with renal fibrosis in patients undergoing renal biopsy

OBJECTIVES: Progressive renal disease is characterized by histological changes in the kidney and fibrosis is a common outcome. Renal biopsy is the only diagnostic tool to evaluate these histopathological changes. Pentraxin-2 (PTX-2) is an anti-inflammatory constitutive plasma protein associated with the innate immune system. Recently, as a biomarker, the circulating level of PTX-2 is shown to be decreased in chronic fibrotic diseases. In this study, we aimed to investigate the relationship between renal fibrosis severity and serum PTX-2 levels in patients undergoing renal biopsy. METHODS: This cross-sectional study included 45 patients and 16 healthy individuals (HIs). The severity of renal fibrosis was evaluated according to the Banff and Sethi scoring systems by the same pathologist. PTX-2 was measured by an enzyme-linked immunosorbent assay and compared with the demographical, clinical, biochemical, and histopathological data of the patients and HIs. RESULTS: PTX-2 levels were lower in the biopsy group than in the HI group (p=0.12). Patients with moderate renal fibrosis had significantly lower serum PTX-2 levels than those in patients with minimal and mild fibrosis (p=0.017 and p=0.010, respectively). PTX-2 concentrations were correlated with serum albumin (r=0.30, p=0.016), and were negatively correlated with serum creatinine levels (rho=-0.42, p=0.01) and body mass index (r=-0.32, p=0.011). CONCLUSIONS: The results indicated that PTX-2 levels are significantly lower in patients with renal fibrosis than HIs, and declining further in patients with severe fibrosis.

The effect of pseudoexfoliation syndrome on choroidal thickness in open-angle glaucoma / O efeito do glaucoma pseudoesfoliativo sobre a espessura da coroide em comparação com o glaucoma de ângulo abertos

ABSTRACT Purpose: To investigate the effect of pseudoex foliation syndrome on choroidal thickness as compared with healthy individuals and subjects with primary open-angle glaucoma. Methods: This prospective, randomized study included 30 primary open angle glaucoma patients and 30 pseudoexfoliation glaucoma patients with similar demographic characteristics and 30 eyes of 30 healthy individuals comprised the control group. Regular optic nerve and macular images were obtained using a Cirrus HD spectral domain optical coherence tomography instrument, along with macular choroidal thickness measurements with enhanced depth imaging mode. Results: Age, sex, and axial length values were similar among the three groups (p>0.05). The primary open angle glaucoma and pseudoexfoliation glaucoma groups had comparable levels of glaucomatous damage. The mean subfoveal choroidal thickness values in the primary open angle glaucoma, pseudoexfoliation glaucoma, and control groups were 271.80 ± 19.96 μm, 241.43 ± 32.47 μm, and 268.03 ± 24.50 μm, respectively. The pseudoexfoliation glaucoma group had the lowest choroidal thickness values of the three groups (p values: pseudoexfoliation-control: 0.001; pseudoexfoliation-primary open angle glaucoma: <0.001, primary open angle glaucoma-control: 0.516, independent samples t-test). Conclusion: The macular choroid was thinner in patients with pseudoexfoliation glaucoma, as compared with both healthy individuals and open-angle glaucoma patients with similar degrees of glaucomatous damage.

RESUMO Objetivo: Investigar o efeito do glaucoma pseudoexfoliativo sobre a espessura da coroide em comparação com indivíduos saudáveis e com glaucoma primário de ângulo aberto. Métodos: Este estudo prospectivo e randomizado incluiu 30 pacientes com glaucoma primário de ângulo aberto e 30 com glaucoma pseudoexfoliativo, com características demográficas semelhantes e 30 olhos de 30 indivíduos saudáveis compuseram o grupo controle. Imagens da área macular e do nervo óptico foram obtidas usando um tomógrafo por coerência óptica no domínio espectral do modelo Cirrus HD, juntamente com medições da espessura da coroide na área macular através do modo de imagem de profundidade realçada. Resultados: Os valores de idade, sexo e comprimento axial foram semelhantes nos três grupos (p>0,05). Os grupos de glaucoma primário de ângulo aberto e de glaucoma pseudoexfoliativo tinham níveis comparáveis de lesões glaucomatosas. Os valores médios da espessura subfoveal da coroide nos grupos do glaucoma primário de ângulo aberto, glaucoma pseudoexfoliativo e de controle foram 271,80 ± 19,96 μm, 241,43 ± 32,47 μm e 268,03 ± 24,50 μm, respectivamente. O grupo glaucoma pseudoexfoliativo apresentou os menores valores de espessura de coroide dos três grupos (valores de p: pseudoexfoliativo-controle: 0,001; pseudoexfoliativo-glaucoma primário de ângulo aberto: <0,001, controle de glaucoma primário de ângulo aberto: 0,516; teste de t de amostras independentes). Conclusão: A coroide na área macular era mais fina em pacientes com glaucoma pseudoexfoliativo, quando comparada com indivíduos saudáveis e pacientes com glaucoma de ângulo aberto com graus similares de lesão glaucomatosa.
