RESUMEN

OBJECTIVE: Methotrexate (MTX) is a folic acid antagonist used in chronic inflammatory diseases and various cancer treatments. Although the main mechanism of the toxic effect of MTX is not known, it is stated that it causes oxidative stress and inflammation. Alpha-linolenic acid (ALA) protects against oxidative stress, apoptosis, and inflammation. For this reason, we aimed to find out the useful effect of ALA on MTX-induced nephrotoxicity MATERIALS AND METHODS: The mice were divided into 4 groups randomly. The control group was treated with physiological saline solution; the ALA group was treated with ALA (200 mg/kg) by gavage; MTX-treated group received 20 mg/kg i.p. (intraperitoneal) MTX; and MTX+ALA treated group received 20 mg/kg i.p. MTX and ALA 200 mg/kg by gavage. All of the drugs were performed once a day for 9 days. RESULTS: Alpha-linolenic acid significantly decreased oxidative stress parameters and MTX-induced inflammatory and apoptotic mediators. Furthermore, histopathological examination showed that MTX induced significant edematous damage, and ALA treatment attenuated this damage in renal tissue. CONCLUSIONS: Our results revealed that ALA may be helpful against MTX-induced nephrotoxicity in mice via its antioxidant and anti-inflammatory properties.

RESUMEN

OBJECTIVES: This empirical study investigated the relationship between globalisation and suicide rates. We examined whether there is a beneficial or harmful relationship between economic, political and social globalisation and the suicide rate. We also estimated whether this relationship differs in high-, middle- and low-income countries. STUDY DESIGN: Using panel data from 190 countries over the period 1990-2019, we examined the relationship between globalisation and suicide. METHOD: We compared the estimated effect of globalisation on suicide rates using robust fixed-effects models. Our results were robust to dynamic models and models with country-specific time trends. RESULTS: The effect of the KOF Globalisation Index on suicide was initially positive, leading to an increase in the suicide rate before decreasing. Concerning the effects of economic, political, and social dimensions of globalisation, we found a similar inverted U-shaped relationship. Unlike the middle-income and high-income countries, we found a U-shaped relationship for the case of low-income countries, indicating that suicide decreased with globalisation and then increased as globalisation continues to increase. Moreover, the effect of political globalisation disappeared in low-income countries. CONCLUSION: Policy-makers in high- and middle-income countries, below the turning points, and low-income countries, above the turning points, must protect vulnerable groups from globalisation's disruptive forces, which can increase social inequality. Consideration of local and global factors of suicide will potentially stimulate the development of measures that might reduce the suicide rate.

RESUMEN

Summary: Background. There is limited data about the natural course of egg allergy in the literature. We aimed to analyze the factors that can affect the tolerance or persistence of egg allergy. Methods. A total number of 126 IgE- mediated egg allergic patient who had data about tolerance gaining were included in the study. Demographic and laboratory data were recorded retrospectively. Kaplan-Meier curves was used for estimation of resolution and the factors related to resolution by Cox regression model. Results. Among 126 patients 81 (64.2%) had gained tolerance with a median survival time of 48 months (min 12- max 121). Tolerance was gained in 22.2% (28) of these patients in the first 2 years, in 46.8% (49) 2-6 years, 3.1% (4) between 7-12 years. In univariate analysis, no history of anaphylaxis (at initiation or during OFC) (Hazard ratio 2.193; 95%CI 1.309-3.674, p = 0.003), baseline sIgE level less than 8.2 (Hazard ratio 11.292; 95%CI 2.766-46.090, p = 0.001) and baseline egg SPT less than 11 mm (Hazard ratio 2.906; 95%CI 1.424-5.930, p = 0.003) were found to be related to earlier resolution of egg allergy. In multivariate analysis only anaphylaxis was significantly related to later resolution (Hazard ratio: 6.547; 95%CI 15.80-27.434, p = 0.01). Conclusions. Higher levels of egg sIgE, skin prick test induration and anaphylaxis at onset or during oral food challenge, can give hint about persistence of egg allergy.

RESUMEN

OBJECTIVE: The number of studies in the field of andrology is increasing day by day, but a bibliometric study covering the entire literature on andrology has not yet been conducted. This bibliometric study aims to shed light on the question of where we came from and where we are going in andrology from past to present. It also aimed to summarize the intellectual structure of andrology to reveal global productivity and identify and map the latest trends of scientific articles published in the field of andrology. MATERIALS AND METHODS: 16,659 articles published between 1980 and 2022 were extracted from the Web of Science and analyzed using various statistical methods. Bibliometric network visualization maps revealed trending topics, global productivity, the most influential studies, and international collaborations. Spearman's correlation analysis was used for determining correlations. RESULTS: The top three productive countries were United States of America (3,452; 20.7%), China (2,300; 13.8%), and Germany (1,069; 6.4%). The top two most productive authors were Agarwal A. (n=130) and Nieschlag E. (n=130). The most productive institution was the Egyptian Knowledge Bank (n=422). From past to present, the most studied subjects were testis, male infertility, spermatozoa, testosterone, infertility, erectile dysfunction, spermatogenesis, sperm, prostate cancer (PCA)/neoplasms, oxidative stress, fertility/fertilization, semen, rat(s), apoptosis, azoospermia, sperm motility, human and varicocele. CONCLUSIONS: The trend topics that have been researched more in recent years include erectile dysfunction, oxidative stress, prostate cancer, sperm quality, sperm parameters, infertility, premature ejaculation, diabetes mellitus, obesity, prognosis, sperm DNA fragmentation/damage, antioxidant, asthenozoospermia, varicocelectomy, COVID-19, inflammation, prostatectomy, metabolic syndrome, hypogonadism, benign prostatic hyperplasia, lower urinary tract symptoms, meta-analysis, sexual dysfunction, peyronie's disease, and proliferation. We identified the research leadership of China, Japan, Turkey and India, in addition to Western countries, such as the USA and European countries.

RESUMEN

BACKGROUND: The widespread use of digital devices causes adolescents to spend long periods of time in front of the screen. AIMS: This study aimed to analyze the impacts of digital game addiction on the musculoskeletal system of secondary school children in Kayseri. PATIENTS AND METHODS: A total of 1000 healthy children have been included. A questionnaire, which has been prepared by the researchers and questions children's socio-demographic knowledge, sport habits, durations of study, types of digital tools they use to play games, using positions and durations of use, has been applied to the children. A visual analog scale was used to assess pain intensity. Game addiction has been evaluated through Computer Game Addiction Scale for Children. RESULTS: Between computer and phone use and neck pain, a significant correlation has been found (P < 0.05). Between game addiction and wrist, back and low back pain, a significant correlation has been detected. While males use more computer, tablet and are more addicted to games, the scores of head, wrist and back pain in females have been found out to be significantly high. CONCLUSIONS: As they cause musculoskeletal problems, the higher the time children consume in front of digital devices and the more they use it in wrong posture; the more the complaints about pain are.

RESUMEN

The aim of this study was to compare locking reconstruction plates with caudobuccally screwed custom mandibular reconstruction plates in bridging lateral mandibular segmental defects. The in vitro study was conducted on 13 polyurethane mandibles. A total of 7 mandibles with lateral segmental defects were bridged with locking reconstruction plates in group I, 6 mandibles with the same standard defect were bridged with caudobuccally screwed customised reconstruction plates in group II. Mean yield displacement, yield load, and displacement at 80 N (Newtons), 100 N, 200 N, 300 N loading were compared among the 2 groups. The mean (SD) displacement for Group I was 11.27 (3.6) mm, Group II was 21.08 (2.5) mm. Group II had significantly greater (p=0.0001) displacement when compared with Group I. The mean (SD) force before failure for Group I was 638.4 N (127.2), Group II was 1398. 3 N (162.7). Group II withstood significantly greater force than Group I (p=0.0001). The study reveals that the caudobuccally screwed custom reconstruction plates can significantly enhance yield load as preserving the preoperative shape of the face and mandible.

RESUMEN

It is known that patients suffering from neurological illnesses have an increased risk of burn injuries. These burns are often very severe and lead to poor outcomes. To date, only a few studies have evaluated the impact of pre-existing neurological illnesses on the outcome of burn injuries. None of them performed a regression analysis regarding specific influence on mortality. Between 1996 and 2016, 1475 patients were admitted to the BICU of a specialized German burn center: 26 had less than 1% TBSA burned and were excluded; 177 had pre-existing neurological disorders (group N). 87 patients with psychological disorders were excluded. 1185 patients without neurological or psychological disorders formed the control group. Length of hospital stay, TBSA and number of operations were analyzed using the chi-squared test and Mann-Whitney U-test. Additionally, mortality was evaluated using the logistic regression analysis adjusted for known outcome predictors. Mean age of the patients in the control group was 41.53 years with a BICU stay of 18 days, TBSA of 18.25% and mortality rate of 12.4%; 23.7% had inhalation injuries. Patients in group N had a mean age of 54.63 years, a BICU stay of 27 days, mean TBSA of 20.97%; 31.1% had inhalation injuries and mortality was 20.3%. Patients with neurological disorders were older and showed higher affected TBSA, higher rates of inhalation injury, mortality and affected TBSA, and a longer stay in the BICU compared to the control group. Nevertheless, pre-existing neurological disorders alone had no significant influence on mortality.


Il est avéré que les patients souffrant de pathologie neurologique ont un risque plus élevé de brûlure. Elles sont souvent particulièrement graves et d'évolution défavorable mais la littérature à ce sujet reste pauvre et aucune étude n'a utilisé de régression logistique pour évaluer la corrélation pathologie neurologique- évolution d'une brûlure. Entre 1996 et 2016, 1 475 patients ont été hospitalisés en réanimation spécifique dans un CTB allemand. Vingt- six d'entre eux, brûlés sur moins de 1% SCT, n'ont pas été inclus dans l'étude, pas plus 87 patients psychiatriques si bien que 177 patients souffrant de pathologie neurologique (N) ont été comparés à 1 185 n'en souffrant pas (C). Les durées d'hospitalisation, la surface brûlée et le nombre d'interventions chirurgicales ont été analysée en utilisant C² ou Mann-Whitney. En outre, nous avons effectué une régression logistique étudiant la mortalité, en utilisant les facteurs connus de mortalité. Le groupe C avait 41,53 ans, souffrait de brûlures sur 18,25% SCT, avait inhalé des fumées dans 23,7% des cas, avait un taux de mortalité de 12,4% et restait 18 j en réanimation. Dans le groupe N, ces chiffres étaient respectivement de 54,63 ans, 20,97% SCT, 31,1% de fumées, 20,3% de mortalité et 27 jours en réa. Tous les chiffres étudiés étaient plus élevés dans N que dans C. Toutefois, l'existence de comorbidité neurologique n'apparaissait pas un critère indépendant de mortalité.

RESUMEN

Nowadays, the incidence of acute bacterial skin and skin structure infection (ABSSSI) is increasing. The increased bioavailability and reduced drug resistance of antibiotics are crucial to obtain a more effective treatment response in these infections. These favorable properties could be achieved by different drug delivery systems such as liposomes. In this study, nanosized, radiolabeled tedizolid phosphate liposomal formulations were prepared and evaluated with their in vitro cellular binding capacity and biocompatible profile for topical treatment of ABSSSI. Liposomes were characterized by evaluation of their visual inspection, particle size (about 190-270 nm), zeta potential value (around 0), and encapsulation efficiency (nearly 10%). The release rate of tedizolid phosphate from liposomes was also studied using dialysis membranes and evaluated kinetically. The stability of formulations was observed at three different temperatures and humidity conditions for 28 days. Afterward, liposomes were labeled with 99mTc, and the optimal amount of reducing agent (stannous chloride) was determined as 500 µg in this direct labeling procedure. All liposome formulations were successfully radiolabeled with high efficiency and exhibited high radiochemical purity (> 80%) during 6 h in different media. Furthermore, the cellular bindings of liposomal formulations were evaluated in human skin fibroblast cells by measuring the radioactivity. Higher radioactivity values were obtained in CCD-1070Sk cells incubated by liposome formulations compared to sodium pertechnetate. This finding suggested that liposomal formulation increased the cellular binding of radioactivity. By the result of our study, nanosized, tedizolid phosphate encapsulated liposome formulation was found to be a favorable carrier system in the treatment of ABSSSI.

RESUMEN

BACKGROUND/OBJECTIVE: Although a number of studies report an important effect of smoking on disc degeneration and herniation, others did not identify such a relationship. The purpose of this study was to assess the relationship of lumbar disc degeneration with hemoglobin value and smoking. METHODS: The study included 200 adult patients who presented to the neurosurgery polyclinic with a complaint of back pain. Smoking habits were classified as "smoking for more than 10 years", "smoking for less than 10 years", and "not smoking". Lumbar disc degeneration was classified on modified Pfirrmann score according to lumbar MR images. Degeneration level was compared according to smoking group on Kruskal-Wallis test. The relationship between hemoglobin value and disc degeneration according to smoking group was assessed on the Spearman correlation coefficient. RESULTS: Disc degeneration values were significantly different between groups in L5-S1, L4-L5 and L3-L4 (P=0.018, P=0.012, P=0.038). Degeneration levels in L5-S1 in those who did not smoke were significantly lower than in those who smoked for both less and more than 10 years (P=0.048, P=0.022). No significant differences were found in degeneration level between those who smoked for more versus less than 10 years. For L3-L4 degeneration, there was a significant relationship with hemoglobin value in the group that did not smoke and in the group that smoked for more than 10 years (r=-0.395; P=0.009, r=0.329; P=0.018). CONCLUSION: This study found that, when risk factors such as systemic disease, heavy working conditions, obesity, trauma and family history were excluded, smoking increased lumbar disc degeneration. In addition, chronic smoking was found to increase hemoglobin values.

RESUMEN

BACKGROUND: The global prevalence of allergic diseases has increased dramatically in recent years and are now recognized as significant chronic diseases worldwide. One of the most important allergens that causes allergic diseases is house dust mites. OBJECTIVE: This study aims to present a bibliometric overview of research published on dust mites between 1980 and 2018. METHODS: Articles published from 1980 to 2018 were analyzed using bibliometric methods. The keywords "Dust mite*," and "Dermatophagoides" were used in the Web of Science (WoS). Simple linear regression analysis was used to estimate the number of future publications on this subject. RESULTS: A total of 4742 publications were found, 2552 (53.8%) of them were articles. Most of the articles were on subjects related to immunology (1274; 49.9%) and allergy (1229; 48.1%). Clinical and Experimental Allergy (222; 8.7%) was the journal with the most publications. The USA was the country that most contributed to the literature with 461 (18.1%) articles. The countries producing the most publications on this subject were developed countries. The most active author was W.R. Thomas (66; 2.5%). The most productive institution was the University of Western Australia (91; 3.6%). The most cited article was published in the New England Journal of Medicine. CONCLUSION: According to the findings, developed countries were the most productive in publishing on house dust mites. By planning multinational research rather than regional studies, it may be suggested that researchers in underdeveloped or developing countries could also conduct more research on this subject

RESUMEN

Locomotion at low Reynolds numbers encounters stringent physical constraints due to the dominance of viscous over inertial forces. A variety of swimming microorganisms have demonstrated diverse strategies to generate self-propulsion in the absence of inertia. In particular, ameboid and euglenoid movements exploit shape deformations of the cell body for locomotion. Inspired by these biological organisms, the 'push-me-pull-you' (PMPY) swimmer (Avron J Eet al2005New J. Phys.7234) represents an elegant artificial swimmer that can escape from the constraints of the scallop theorem and generate self-propulsion in highly viscous fluid environments. In this work, we present the first experimental realization of the PMPY swimmer, which consists of a pair of expandable spheres connected by an extensible link. We designed and constructed robotic PMPY swimmers and characterized their propulsion performance in highly viscous silicone oil in dynamically similar, macroscopic experiments. The proof-of-concept demonstrates the feasibility and robustness of the PMPY mechanism as a viable locomotion strategy at low Reynolds numbers.

RESUMEN

Internal derangement of the temporomandibular joint (TMJ) is usually treated conservatively, but about 5% require surgical treatment. We designed a retrospective study to assess the long-term outcomes of eminectomy combined with discectomy and silastic interpositional graft in 44 patients who had chronic TMJ dysfunction that had not responded to traditional conservative treatment and arthrocentesis. The maximum mouth opening, pain score, Wilkes stage, and clinical dysfunction index were measured before, and two years after, operation. All the patients showed significant improvement in mouth opening and reduced pain scores (p<0.0001 in each case). There were no long-term operative complications, and postoperative magnetic resonance scans showed that the silastic interpositional graft was in a stable position with no evidence of degenerative changes on the surfaces of the joint and no lymphadenopathy.

RESUMEN

BACKGROUND: Pancreatic fistula (PF) is a common complication after pancreatic surgery. It is unclear how microbes in PF fluid affect outcomes and which microbes are present after pancreatoduodenectomy (PD) and distal pancreatectomy (DP). The aim of this study was to compare the microbiological spectrum of PF fluid after PD versus DP, and its association with postoperative complications. METHODS: Bacterial strains and antibiotic resistance rates of bacterial swabs obtained from the PF fluid of patients who underwent DP or PD were analysed. Cultured bacteria were classified as Enterobacterales and as 'other intestinal and non-intestinal microorganisms' based on whether they are typically part of the normal human intestinal flora. RESULTS: A total of 847 patients had a pancreatic resection (PD 600; DP 247) between July 2007 and December 2016. Clinically relevant PF was detected in 131 patients (15·5 per cent). Bacterial swabs were obtained from 108 patients (DP 47; PD 61), of which 19 (17·6 per cent) were sterile. Enterobacterales were detected in 74 per cent of PF fluid swabs after PD, and in 34 per cent after DP. Infected, polymicrobial or multidrug-resistant PF fluid was more common after PD (rates of 95, 50 and 48 per cent respectively) than after DP (66, 26 and 6 per cent respectively). Patients with higher grade complications (Clavien-Dindo grade IV-V) or grade C PF had more Enterobacterales and multidrug-resistant Enterobacterales in the PF fluid after DP. CONCLUSION: Enterobacterales and multidrug-resistant bacteria are detected frequently after PD and DP, and are associated with more severe complications and PF in patients undergoing DP.


ANTECEDENTES: La fístula pancreática (pancreatic fistula, PF) es una complicación frecuente de la cirugía pancreática. No está claro cómo los microorganismos que se encuentran en el líquido de la PF (pancreatic fistula fluid, PFF) afectan los resultados y qué microbios están presentes después de la duodenopancreatectomía (pancreaticoduodenectomy, PD) y de la pancreatectomía distal (distal pancreatectomy, DP). El objetivo de este estudio fue comparar el espectro microbiológico del PFF después de PD versus DP y su asociación con las complicaciones postoperatorias. MÉTODOS: Se analizaron las cepas bacterianas y las tasas de resistencia a los antibióticos de las muestras bacterianas obtenidas del PFF de pacientes de nuestra institución que se sometieron a DP o PD. Las bacterias identificadas en los cultivos se clasificaron en "enterobacterias" y "otros microorganismos intestinales y no intestinales" en función de si típicamente forman parte de la flora intestinal humana normal o no. RESULTADOS: Un total de 847 pacientes se sometieron a resección pancreática (PD: 600, DP: 247) entre julio de 2007 y diciembre de 2016, y se detectó FP clínicamente relevante en 131 pacientes (15,5%). Se obtuvieron muestras bacterianas de 108 pacientes (DP n = 47, PD N = 61), de los cuales 19 (18%) eran estériles. Se detectaron enterobacterias en el 74% del PFF después de PD y en el 34% después de DP. El PFF infectado, con flora polimicrobiana o flora multirresistente fue más frecuente después de la PD (95,1%, 50%, 47,5%, respectivamente) que después de la DP (66,0%, 25,8%, 6,4%, respectivamente). Los pacientes con complicaciones de grado superior (Clavien-Dindo 4/5) o PF grado C presentaron más enterobacterias y enterobacterias multirresistentes en el PFF después de DP. CONCLUSIÓN: Las enterobacterias y las bacterias multirresistentes se detectaron con frecuencia después de la PD y la DP, y se asociaron a complicaciones más graves y PF en pacientes sometidos a DP.

RESUMEN

BACKGROUND: Monitoring of chemokines, CXCL9 and CXCL10, in serum may present a non-invasive detection method for rejection. OBJECTIVE: To investigate the relationship between urinary levels of CXCL9 and CXCL10 and graft function following renal transplantation. METHODS: 75 living-related donor renal transplant recipients were studied. Urinary levels of chemokines were collected pre-operatively, on post-operative 1st day, 7th day, 1st month, 3rd month, and at the time of rejection. Chemokines levels were assayed using and enzyme-linked immunosorbent assay. RESULTS: Clinical variables were monitored. 10 (15%) patients had biopsy-proven rejection during the follow-up period. The urinary CXCL9 level in those with rejection was significantly higher than that in those with non-rejection group at the 1st day (p<0.001), 7th day (p<0.001), and at the time of rejection (p=0.002). The urinary CXCL10 level was also significantly higher in those with rejection compared with non-rejection group at 1st day (p<0.001), 7th day (p<0.001), and at the time of rejection (p=0.001). Serum creatinine level was strongly correlated with the urinary CXCL9 and CXCL10 levels at the time of rejection (r=0.615, p=0.002; and r=0.519, p=0.022, respectively). Among those with T cell-mediated rejections the mean urinary CXCL10 level increased to as high as 258.12 ng/mL. CONCLUSION: Urinary CXCL9 and CXCL10 levels might have a predictive value for T cell-mediated rejection in early post-transplantation period. Measurement of urinary CXCL9 and CXCL10 levels could provide an additional tool for the diagnosis of rejection.

RESUMEN

INTRODUCTION: Cardiovascular disease is the leading cause of mortality in kidney transplant recipients. Rituximab is widely used in kidney transplantation for a variety of situations, and rituximab may inhibit some cytokines and antibodies that may play an active role in the atherosclerotic process. The aim of the study was to evaluate the efficacy of rituximab on atherosclerosis biomarkers in kidney transplant recipients. METHODS: All patients, 18 years of age and older, who underwent kidney transplantation and received at least 1 dose of 375 mg/m2 rituximab were considered for participation in this study. The primary study endpoint was the development of cardiovascular diseases after rituximab therapy. The secondary endpoint was the onset of cytomegalovirus (CMV) disease or biopsy-confirmed BK virus nephropathy. In addition, comparison of atherosclerosis biomarkers was performed between study and control groups. RESULTS: There were no cardiovascular events observed during follow up. Only 8 patients in the study group suffered from CMV disease during follow up. Serum interleukin 10 levels were significantly higher in the rituximab group compared with the control group, although anti-oxidized low-density lipoprotein levels were lower in the rituximab group compared with the control group, though this did not achieve statistical significance. DISCUSSION: Rituximab treatment may increase the risk of CMV reactivation and decrease lymphocyte counts and interleukin 10 levels; however, significant decreases in all atherosclerotic-related biomarkers have not been shown in our study.

RESUMEN

INTRODUCTION: Seasonal influenza is an important cause of morbidity and mortality in the post-transplant period; therefore, the influenza vaccination has been recommended for all kidney transplant recipients before the influenza season. However, at least theoretically, the introduction of antigens via vaccines may trigger rejection attacks by causing an antibody response. In this study, we examined the development of de novo panel reactive antibody (PRA) development against the influenza vaccine in kidney transplant recipients. MATERIALS AND METHODS: Overall, 41 kidney transplant recipients who received the influenza vaccination and 50 kidney transplant recipients (study group) who refused to receive the influenza vaccination (control group) were enrolled in the study. Following basal biochemistry examination, the inactivated trivalent influenza vaccine was administered intramuscularly. Panel reactive antibodies were screened in all patients before and after vaccination on days 30 and 180. The primary outcome variable was development of de novo panel reactive antibodies. RESULTS: One patient in the study group developed de novo class I and II PRA at 6 months after vaccination (P > .05), while no antibody development was noted in the control group. Graft dysfunction or biopsy-confirmed rejection was not observed during the follow-up period in both groups. CONCLUSION: The influenza vaccination is generally effective and safe in solid organ transplant recipients. The vaccination procedure has the potential to trigger antibody development and occurrence of rejection. Therefore, vaccinated kidney transplant recipients should be monitored more carefully with regard to PRA; if the graft deteriorates, a rapid transplant biopsy should be performed.

RESUMEN

Human immunodeficiency virus (HIV) infection has traditionally been considered an absolute contraindication for transplantation because immunosuppression will accelerate the disease progression and increase mortality. New antiretroviral agents have given rise to new perspectives and transplantation practices. Now renal transplantation is the gold standard treatment for end-stage renal disease in HIV-infected patients, but increased rejection and toxicity rates and compliance with treatment are important issues. Therefore, patient selection and follow-up should be done carefully in this patient group. Here we present a 51-year-old, male, HIV-infected patient who was diagnosed with HIV at his routine serologic investigation at 2015. Highly active antiretroviral therapy was initiated. One haplotype-matched kidney transplantation from a deceased donor was performed on October 19, 2016. Induction therapy was not administered, and the immunosuppressive regimen included tacrolimus, mycophenolate mofetil, and prednisolone. After 26 months, serum creatinine was 1.1 mg/dL and proteinuria 0.1 g/day. There was no development of donor-specific antibodies. The patient's current HIV viral load remains undetectable (and had been the entire time post-transplantation) while his CD4+ T-cell count currently is 543/mm3.

RESUMEN

BACKGROUND: There are differences in pharmacokinetic of mycophenolic acid among individuals. The UGT1A9 enzyme is of special interest since it is the main enzyme involved in the glucuronidation of MPA. Single nucleotide polymorphisms in the UGT1A9 gene may be responsible for individual differences in the pharmacokinetics of MPA. The aim of this study was to explain MPA pharmacokinetics in UGT1A9 1399 C > T polymorphisms in Turkish renal transplant patients. PATIENTS AND METHODS: One hundred and twenty-five living-donor transplant recipients and 100 healthy control subjects underwent UGT1A9 1399 C > T genotyping using polymerase chain reaction-restriction fragment length polymorphism. Concentrations of MPA were determined with Cloned Enzyme Donor Immunoassay (CEDIA). Besides that, all the patients were monitored for acute rejection and graft function during the study period. RESULTS: The UGT1A9 1399 C > T CC, CT, and TT genotype frequencies among patients were, respectively, 68.0%, 23.2%, and 8.8%. The CC, CT, and TT genotype frequencies among controls were, respectively, 63.0%, 23.0%, and 14.0%. There was no significant difference between patients and controls (p = .480, p = .999, p = .286, respectively). At first month, respectively, through blood concentrations of MPA were significantly higher in UGT1A9 1399 C > T TT carriers than in CT and CC carriers (p = .046). The doses for these patients were lower at first month (p = .021). Acute rejection episodes were not associated with the CC vs CT or TT genotypes (p = .064). CONCLUSIONS: Our results demonstrated a correlation between the UGT1A9 1399 C > T polymorphism and MPA pharmacokinetics among renal transplant patients. Determination of UGT1A9 polymorphism may help to achieve target of MPA blood concentrations.

RESUMEN

INTRODUCTION: Although grayscale ultrasound and color Doppler ultrasound characteristics of the torsed testis are well established in the literature, less is known about its anatomic partner: the epididymis. OBJECTIVE: The purpose of this study was to describe the ultrasound characteristics of the epididymis in pediatric patients with testicular torsion, and to describe their potential role as prognostic criteria for testicular salvage outcomes. STUDY DESIGN: During a retrospective review of 217 pediatric patients with acute testicular torsion during 2009-2016, morphological features of the epididymis from scrotal ultrasounds (size, parenchymal characteristics, and vascular flow of both epididymis heads), as well as patient demographics, time duration, surgical outcomes, histopathology results, and follow-up periods were analyzed. RESULTS: Mean epididymis size and twisting degree were significantly higher in the torsed testes than in the contralateral epididymis (P < 0.001) (Summary table). Cystic structures in the epididymis were identified: a higher number of cysts was associated with testicular non-viability (P = 0.025) and higher twisting degree (P = 0.017). Histopathologic examination showed that these spaces were infiltrated connective tissue most likely formed by venous congestion and vessel rupture. DISCUSSION: Scrotal ultrasound can provide information on testicular morphology and viability, as well as morphological changes in the epididymis over time in pediatric patients with testicular torsion. These findings may provide potential prognostic information regarding testicular viability, as a higher number of cystic spaces in the epididymis was associated with a higher rate of testicular non-viability and a higher twisting degree. In addition, the epididymis size (volume) can change during the time course of the ischemic state. CONCLUSIONS: This was the first study to describe and analyze epididymis ultrasound findings in pediatric patients with testicular torsion and to correlate them with testicular salvage outcomes. Further prospective studies are needed to determine the role of epididymis ultrasound findings as a potential pre-operative prognostic tool.
