AbstractPrevious studies have reported negative impacts of long‐term dialysis on kidney transplantation (KTx) outcomes. However, advances in surgical techniques, immunosuppressive therapies, and post‐transplant monitoring have led to an impressive increase in patient and allograft survival. Thus, the number of KTx among patients on long‐term dialysis is increasing. We evaluated the influence of dialysis duration on the outcome of living donor KTx. Between January 2000 and October 2011, we performed 1098 first KTx from living donors in adults (>18 years). We divided the patients into six groups, A group: pre‐emptive kidney transplantation, B group: <24 months duration of dialysis, C group: 25–60 months duration, D group: 61–120 months duration, E group: 121–240 months duration, and F group: ≥241 months duration. The 5‐year patient survival rates were 95.7, 98.8, 99.0, 99.0, 97.3, and 100% in groups A–F, respectively. The 5‐year graft survival rates were 91.3, 95.6, 94.2, 96.3, 90.7, and 100% in groups A–F, respectively. No significant differences were observed in patient or graft survival among the six groups. Longer dialysis duration was correlated with lower rates of preoperative hypertension and diabetes mellitus. Survivors of long‐term dialysis tended to be in good compliance with self‐management. If recipients of living KTx have few complications, good prognoses are expectable even if dialysis periods are very long.

Authors: Milosavljevic Marianna , Noble Gary 
Published: February 2014

AbstractAimThe concept of burnout has been examined in the literature for over 35 years, and has been historically associated with those professions that deal with particularly complex cases. Although dietitians have received less attention, they face similar pressures and must cope with an environment that may not support dietetics processes. The aim of the present study was to examine the burnout level among public hospital dietitians in New South Wales (NSW) and to determine the variables associated with burnout and to compare these findings to other studies among health‐care professionals.MethodsThe Maslach Burnout Inventory‐Human Services Survey and a demographic questionnaire were distributed to hospital dietitians employed within the NSW public hospital system during a six‐week period from April to May 2011.ResultsThe dietitians surveyed had low to moderate burnout levels, r = 0.201 (P = 0.003). The three domains of the burnout measure, emotional exhaustion, depersonalisation and personal accomplishment, were investigated separately. The level/grading of the dietitian was associated with higher levels of emotional exhaustion with r = 0.192 (P = 0.004). Depersonalisation was negatively associated with number of children, r = −0.147 (P = 0.02), and positively associated with the number of hours worked, r = 0.154 (P = 0.021). Personal achievement was positively associated with number of children, r = 0.304 (P = 0.006), and negatively associated with the hours of work, r = −0.198 (P = 0.021).ConclusionsThe main findings were the following. The career stage, the size of the hospital and hours of work were the variables significantly associated with the levels of burnout experienced by NSW public hospital dietitians. It also appeared that those dietitians with children and who work part‐time experienced far less emotional exhaustion and depersonalisation than their full‐time counterparts and, interestingly, part‐time workers had higher levels of personal accomplishment.

AbstractChitinases catalyze the conversion of chitin and are produced by a wide range of bacteria. The biological applications of these enzymes have been exploited in food and pharmaceutical industries. We isolated 2 halophilic chitinase‐producing novel strains of bacteria—SCH‐1 and SCH‐2 from Saeu‐jeot, a traditional Korean salted and fermented food made with shrimp (Acetes japonicus). The isolated strains‐ SCH‐1 and SCH‐2 were Gram‐positive, rod‐shaped, endospore‐forming facultative anaerobes, with strain SCH‐2 showing peritrichous flagella. Molecular characterization of the 16S rRNA gene identified the strains SCH‐1 and SCH‐2 as Bacillus sp. and Paenibacillus sp. respectively. Basic Local Alignment Search Tool and subsequent phylogenetic analysis of strain SCH‐1 showed an identity of 97.83% with Bacillus cereus ATCC 14579 (NR_074540), whereas strain SCH‐2 showed an identity of 99.16% with Paenibacillus lautus JCM 9073 (NR_040882). Furthermore, the SCH‐1 strain could use glucose, N‐acetyl glucosamine, esculin, and maltose as carbon source substrates. Cellular fatty acid analysis showed that iso‐C15:0 and anteiso‐C15:0 are the major acids in strain SCH‐1 and SCH‐2, respectively. The SCH‐1 strain showed a higher chitinase activity at 15.71 unit/mg protein compared with SCH‐2 strain. Chitinase isozymes of Bacillus sp. SCH‐1was expressed as 2 bands having sizes of 41 and 50 kDa, and as 4 bands with sizes of 30, 37, 45.7, and 50 kDa in Paenibacillus sp. SCH‐2. The rich chitinase activity with the isozyme profiles of the isolated Bacillus and Paenibacillus strains provide advancement in the study of fermentation and may play putative functions in the chitin bioconversion of sea crustacean foods.

Published: February 2014

AbstractAlthough the evidence of insect oviposition on plant organs has been reported from the late Paleozoic to the Miocene, record from the middle Jurassic is still blank. This paper reports a significant evidence of insect oviposition on plant leaf from the middle Jurassic for the first time. The ovipositional scar is distributed on the abaxial surface of Sphenobaiera leaf (Ginkgoales) from the middle Jurassic Daohugou Formation of Inner Mongolia, China. A new ichnospecies Paleoovoidus venustus sp. nov. is described. The scar is elliptic to oval, arranged in longitudinal rows between leaf veins with almost regular distance, with its long axis paralleling to the leaf venation. This discovery adds new information to the morphology of insect endophytic oviposition probably produced by Odonata existed in a terrestrial ecosystem ∼165 Ma ago. The new materials also provide important data for the study of insect reproductive biology, plant‐insect interaction and coevolution, as well as understanding the paleoclimate and palaeoenvironment during that time in northeast China.

AbstractExtensive mass transport deposits (MTDs), which form a significant component of the stratigraphic record in ancient and modern deep water systems, mostly distributed in the continental margin of ocean basins worldwide. To date, no large‐scale MTDs have been found in Chinese terrestrial basins. Based on integrated analysis of the seismic, drilling, core and logging data, this article report MTDs have been found in Songliao terrestrial basin (SLTB), Northeast China. During the depositional period of the Upper Cretaceous Qingshankou Formation, slope break of lacustrine basins was an ideal discharge place for gravity depositions. Regional sedimentary study of MTDs reveals that Cretaceous‐age MTDs in SLTB were deposited in slope‐break environments by slide, slump and debris flow, and MTDs were mixed with little turbidite simultaneously. Besides the massive aspect, key features of MTDs are the common presence of deformational structures or soft‐sedimentary deformation, floating shale clasts, boudins, microfaults, distortion beddings, rotated sand debris. Detailed mapping of two three‐dimensional (3‐D) seismic surveys acquired in Yingtai (YT) and Haituozi (HTZ) areas reveals that MTDs are characterized by chaotic, mounded, and transparent seismic reflection. Growth fault, slope gully and geomorphology of the slope break greatly influenced the sedimentary process and external geometry of MTDs, and as a consequence, MTDs in SLTB exhibit classic fan‐like geometry and some special (non‐fan‐like) external geometry. Furthermore, fan‐like MTDs can be divided into three subcategories, including isolated fan, mother‐son fan and stacked fan. Non‐fan‐like MTDs can be divided into two subcategories, strip‐like MTDs and faulted‐pit MTDs. A new sedimentary model has been built for MTDs in SLTB. MTDs have become a new exploration and development target in the SLTB.
Survival Conditions of Folding in Different Depth During Orogenesis‐Deformation in Texas Creek and Chester Dome, USA

Published: February 2014

AbstractA succession of 5 FIA trends (foliation intersection or inflection axes in porphyroblasts) preserved in high temperature‐low pressure regime PreCambrian rocks in the Texas Creek, Arkansas River region reflected by the fold axial plane traces and schistosity data in this region. Similar fold axial plane trace data measured in Palaeozoic rocks in Chester Dome, Vermont, which is high temperature to medium pressure regime, only preserve the effects of the youngest FIAs of the all 5 FIA sets that obtained in this region. The other three FIA sets have no equivalent fold axial planes. This difference from shallow to deeper orogenic regimes reflects decreasing competency at greater pressure with collapse and unfolding of earlier formed folds. The greater overlying load of rocks has tended to flatten all but the very largest early‐formed structures, preserving only those folds that were more recently developed.

AbstractThe distributions of lipids in surface and subsurface sediments from the northern South China Sea were determined. The n‐alkanes were in bimodal distribution that is characterized by a centre at n‐C16–n‐C20 with maximum at C18 (or C19) and n‐C27–n‐C31 as well as at C29 (or C31). The short‐chain alkanes suffered from significant losses due to their slow deposition in the water column, and their presence with a slight even carbon predominance in shallow seafloor sediments was ascribed mainly to the direct input from the benthos. The long‐chain alkanes with odd predominance indicate transportion of terrigenous organic matter. Immature hopanoid biomarkers reflect the intense microbial activity for bacteria–derived organic matter and the gradual increase of maturity with burial depth. Abundant n‐fatty acid methyl esters (n‐FAMEs) that are in distributions coincident with fatty acids were detected in all samples. We proposed that the observed FAMEs originated from the methyl esterification of fatty acids; methanol production by methanotrophs and methanogenic archaea related to the anaerobic oxidation of methane, and sulfate reduction provided an O–methyl donor for methylation of fatty acids. The CH4 released from hydrate dissociation at oxygen isotope stage II of Cores ZD3 and ZS5, which had been confirmed by the occurrence of negative δ13C excursion and spherical pyrite aggregates, could have accelerated the above process and thus maximized the relative content of FAMEs at ZD3‐2 (400–420 cm depth) and ZS5‐2 (241–291 cm depth).
The Development of Stylolites in Carbonate Formation: Implication for CO2 Sequestration
Authors: ZHOU Xuejun , ZENG Zhengwen 
Published: February 2014

AbstractThe impact of CO2 sequestration on the host formation is an issue occurring over geologic time. Laboratory tests can provide important results to investigate this matter but have limitations due to a relatively short timeline. Based on literature review and core sample observation, naturally occurred geological phenomena, stylolites are studied in this paper for understanding CO2 sequestration in deep carbonate formations. Stylolites are distinctive and pervasive structures in carbonates that are related to water‐assisted pressure solution. Pressure solution involving stylolitization is thought to be the main mechanism of compaction and cementation for many carbonates. In parallel, CO2 sequestration in carbonate formation involves extensive chemical reactions among water, CO2 and rock matrix, favoring chemical compaction as a consequence. An analogue between stylolites and CO2 sequestration induced formation heterogeneity exists in the sense of chemical compaction, as both pressure solution in stylolites and CO2 enriched solution in CO3 sequestration in carbonate formations may all introduce abnormal porous regions. The shear and/or tension fractures associated with stylolites zones may develop vertically or sub‐vertically; all these give us alert for long‐term safety of CO2 sequestration. Thus a study of stylolites will help to understand the CO2 sequestration in deep carbonate formation in the long run.

AbstractAimTo retrospectively investigate and compare the effects of tumor necrosis factor alpha inhibitors (TNFi) on hepatic enzymes in ankylosing spondylitis (AS) patients.MethodsA retrospective analysis of the records of 94 AS (66 male, 28 female) patients using TNFi was performed. Patients' clinical data, Bath Ankylosing Spondylitis Disease Activity (BASDAI) scores, erythrocyte sedimentation rate (ESR) and C‐reactive protein (CRP) levels were all examined. Liver function test (LFTs) results of patients before the treatment and 3, 6 and 12 months after treatment with TNFi were investigated. Aspartate transaminase (AST) and alanine transaminase (ALT) levels were investigated as indicators of LFTs.ResultsThe TNFi drugs used were infliximab (n = 28), adalimumab (n = 32) and etanercept (n = 34). Pre‐treatment values of ESR, CRP and BASDAI scores were 28.3 ± 20.1 mm/h, 1.5 ± 1.2 ng/dL and 5.2 ± 0.8, respectively. Following TNFi use there was a statistically significant decrease in disease activity score (P = 0.001). There was a significant increase in LFT at the third month evaluation compared to the initial values, while the average value was within normal range (baseline AST 19.6 ± 10.8 U/L, ALT 19.1 ± 6.4 U/L, third month AST 31.3 ± 21.6 U/L, ALT 28.1 ± 18.1 U/L, P = 0.001). Drug group comparison analysis revealed a significant difference in the adalimumab group value at the end of the first year, but no other significant difference in the data for the other months (P > 0.05). No significant correlation was determined between initial disease activity scores and LFT.ConclusionTNFi use‐associated rises in hepatic enzymes were determined compared to pre‐treatment but the mean values remained within normal limits. Considering the cases in the literature, in daily practice patients must be carefully monitored for liver function before treatment and at follow‐up.

Published: February 2014

Background and AimMesh reinforcement is considered an effective method for anterior compartment prolapse repair. Two common methods of mesh reinforcement involve either transobturator fixation (eg Perigee™) or lateral and apical anchoring (eg Anterior Elevate™). The aim of this study was to assess subjective and objective outcomes after Anterior Elevate and Perigee mesh kit surgery.Materials and MethodsThis was a surgical audit of patients after anterior colporrhaphy (AC) with mesh reinforcement, undertaken at three tertiary urogynaecological centres. All patients were assessed for prolapse recurrence, which was defined as either (i) symptoms of prolapse (vaginal lump/dragging), (ii) ICS POPQ ≥ Stage 2, or (iii) bladder descent ≥10 mm below the symphysis pubis on transperineal ultrasound. Mesh co‐ordinates and organ descent on Valsalva were determined relative to the inferior symphyseal margin.ResultsTwo hundred and twenty‐nine patients with anterior compartment mesh (138 Perigee, 91 Elevate) were assessed at a median follow‐up of 1.09 years (IQR 0.65–2.01). On assessment, 24% (n = 55) had symptoms of prolapse recurrence, 46% (n = 106) had a clinical recurrence, and 41% (n = 95) a recurrent cystocele sonographically. All objective results favoured the Perigee group. The superiority of the Perigee kit remained highly significant (P < 0.0001 for all clinical and ultrasound measures of prolapse recurrence) on multivariate analysis.ConclusionsThis retrospective analysis suggests that apical anchoring such as Anterior Elevate mesh system does not necessarily confer an advantage over the original transobturator mesh fixation technique for anterior compartment reconstruction.

ObjectiveTo compare the vaginal cytology of ovulating and non‐ovulating queens.ProcedureThe study group comprised 15 queens showing behavioural oestrus. Ovulation was induced in 7 (dioestrus group) and 8 were left untreated (postoestrus group). Vaginal smears were collected from all animals prior to ovariohysterectomy on day 7. Epithelial cells were classified as basal‐parabasal, intermediate, superficial, or anucleated superficial cells and counted using computer‐assisted image analysis. From each smear, 50 representative vaginal epithelial cells were chosen. Digital images of cells were taken and cell area, cytoplasm area, nucleus area, cell diameter, cell perimeter, nucleus/cytoplasm ratio and red‐green‐blue (RGB) values were measured using image analysis software. Measurement data were compared between groups.ResultsOvulation induction was successful in all animals. The swabbing procedure in oestrus did not induce ovulation in any postoestrus queens. Mean duration of oestrus was 6.65 ± 0.44 and 4.71 ± 0.32 days (P > 0.05) in the postoestrus and dioestrus queens, respectively. Intermediate cell count averaged 21.43% in dioestrus cats and 10.76% in postoestrus cats (P < 0.05). Epithelial cells in the postoestrus group had higher cell area, cytoplasm area, cell diameter and cell perimeter measurements (P < 0.01). Red (90.9 ± 1.6), green (76.1 ± 1.3) and blue (83.6 ± 1.4) channel values in postoestrus were higher than the values (81.3 ± 0.8, 65.8 ± 0.9 and 74.0 ± 0.7, respectively) in dioestrus (P < 0.01).ConclusionInduction of ovulation in oestrus queens results in a significant increase in the number of intermediate cells and a significant decrease in both the dimensions and RGB values of vaginal epithelial cells on day 7.

Published: February 2014

ObjectiveRetrospective study to determine postoperative continence when correcting intramural ureteral ectopia by transection of the ureter and neoureterostomy, leaving the distal ureter in situ. We hypothesised that the technique would achieve results comparable to previously described surgical techniques.MethodsMedical records for dogs that underwent surgery for correction of unilateral intramural ureteral ectopia were reviewed. Cases (n = 9) of a neoureterostomy where the distal ureter was left in situ were included. Postoperatively, owners were contacted by telephone or email and asked to complete a questionnaire, scoring their dog's urinary continence on a scale from 0 to 2 where 0 was completely continent, 1 was occasional incontinence during excitement or while recumbent and 2 was no improvement in postoperative urinary continence, with the dog having constantly wet perivulvar fur and constant dribbling of urine.ResultsAll dogs showed signs of severe urinary incontinence prior to surgery, including constantly wet perivulvar fur and constant dribbling of urine. Postoperatively, six dogs had a score of 0 and three dogs improved to a score of 1. Time to follow‐up after surgery ranged from 1 to 62 months.ConclusionThe results of this study support our hypothesis. The technique was simple to perform and urinary continence achieved was comparable to that of other techniques. We suggest that this technique should be considered as an alternative for the correction of intramural ureteral ectopia.

ObjectivesTo identify risk factors and develop a model for predicting recurrence of upper urinary tract urothelial carcinoma (UTUC) in the bladder in patients without a history of bladder cancer after radical nephroureterectomy (RNU).Patients and MethodsWe retrospectively reviewed 754 patients with UTUC without prior or concurrent bladder cancer or distant metastasis at 13 institutions in Japan. Univariate and multivariate Fine and Gray competing risks proportional hazards models were used to examine the cumulative incidence of bladder recurrence of UTUC. A risk stratification model and a nomogram were constructed. Two prediction models were compared using the concordance index (c‐index) focusing on predictive accuracy and decision‐curve analysis, which indicate whether a model is appropriate for decision‐making and determining subsequent patient prognosis.ResultsThe cumulative incidence rates of bladder UTUC recurrence at 1 and 5 years were 15 and 29%, respectively; the median time to bladder UTUC recurrence was 10 months. Multivariate analysis showed that papillary tumour architecture, absence of lymphovascular invasion and higher pathological T stage were both predictive factors for bladder cancer recurrence. The predictive accuracy of the risk stratification model and the nomogram for bladder cancer recurrence were not different (c‐index: 0.60 and 0.62). According to the decision‐curve analysis, the risk stratification was an acceptable model because the net benefit of the risk stratification was equivalent to that of the nomogram. The overall cumulative incidence rates of bladder cancer 5 years after RNU were 10, 26 and 44% in the low‐, intermediate‐ and high‐risk groups, respectively.ConclusionsWe identified risk factors and developed a risk stratification model for UTUC recurrence in the bladder after RNU. This model could be used to provide both an individualised strategy to prevent recurrence and a risk‐stratified surveillance protocol.
