The middle-school years (Year 7 to Year 9) is a particular challenge for socially disadvantaged populations, with high proportions of children either repeating school years or dropping out of school. In Australia, a group of particular concern is First Nations children for whom there is a collective effort by all governments to improve education outcomes, although there have been few studies of their transition through the middle-school years. This retrospective study, using individual-level linked data, followed a cohort of 7881 First Nations students for 2 years after enrolment in Year 7 (Y7) in any Northern Territory (NT) government school in the years from 2008 to 2014 to quantify the transitional pathways through middle school and identify the factors associated with faltering progress. We used multinomial multilevel logistic regression to identify the factors associated with school dropout and repeating Y7 or Y8 (Y7/8). Two years after Y7 enrolment, eight in ten First Nations students progressed to Y9 (78.8%), more than one in ten students had dropped out of school (13.3%) before reaching Y9, and one in 12 (7.9%) repeated Y7/8. The likelihood of either dropping out of school or repeating years was higher among students who were enrolled in Y7 when aged less than 11.5 years, had a low Y7 school attendance rate, moved to either interstate or non-government schools and who lived in a remote area. Students who were not born in the NT and those with a record of substantiated child maltreatment during Y7 were more likely to repeat Y7/8. Planning interventions to improve school retention through the middle-school years should consider these factors. [ABSTRACT FROM AUTHOR]

Abstract Background Floating bamboo (Hygroryza aristata) is an endangered species with a narrow native distribution and is renowned for its unique aesthetic qualities, which holds significant ecological and ornamental value. However, the lack of genetic information research, with only one complete plastome available, significantly hampers conservation efforts and further research for this species. Results In this research, we sequenced and assembled the organelle genomes of floating bamboo, including the mitogenome (587,847 bp) and plastome (135,675 bp). The mitogenome can recombine into various configurations, which are mediated by 25 repeat pairs (13 SRs, 6 MRs, 1 LR, and 5 CRs). LR1 and SR5 are particularly notable as they have the ability to combine with other contigs, forming complex repeat units that facilitate further homologous recombination. The rate of homologous recombination varies significantly among species, yet there is still a pronounced positive correlation observed between the length of these repeat pairs and the rate of recombination they mediate. The mitogenome integrates seven intact protein-coding genes from the chloroplast. The codon usage patterns in both organelles are similar, with a noticeable bias towards C and T on the third codon. The gene map of Poales shows the entire loss of rpl6, succinate dehydrogenase subunits (sdh3 and sdh4). Additionally, the BOP clade retained more variable genes compared to the PACMAD clade. Conclusions We provided a high-quality and well-annotated mitogenome for floating bamboo and demonstrated the presence of diverse configurations. Our study has revealed the correlation between repeat length and their corresponding recombination rate despite variations among species. Although the mitogenome can potentially exist in the form of a unicircular in vivo, this occurrence is rare and may not be stable.

Although existing guidelines address electrodiagnostic (EDX) testing in identifying neuromuscular conditions, guidance regarding the uses and limitations of serial (or repeat) EDX testing is limited. By assessing neurophysiological change longitudinally across time, serial electrodiagnosis can clarify a diagnosis and potentially provide valuable prognostic information. This monograph presents four broad indications for serial electrodiagnosis in adult peripheral neurological disorders. First, where clinical change has raised suspicion for a new or ongoing lesion, EDX reassessment for spatial spread of abnormality, involvement of previously normal muscle or nerve, and/or evolving pathophysiology can clarify a diagnosis. Second, where diagnosis of a progressive neuromuscular condition is uncertain, electrophysiological data from a second time point can confirm or refute suspicion. Third, to establish prognosis after a static nerve injury, a repeat study can assess the presence and extent of reinnervation. Finally, faced with a limited initial study (as when complicated by patient or environmental factors), a repeat EDX study can supplement missing or limited data to provide needed clarity. Repeat EDX studies carry certain limitations, however, such as with prognostication in the setting of remote or chronic lesions, sensory predominant fascicular injury, or mild axonal injury. Nevertheless, serial electrodiagnosis remains a valuable and underused tool in the diagnostic and prognostic evaluation of neuromuscular conditions. [ABSTRACT FROM AUTHOR]

Abstract Background Repeat induced abortion is a serious public health issue that has been linked to adverse maternal health outcomes. However, knowledge about repeat induced abortion and its associated factors among reproductive age women in Ghana is very scarce. The objective of this study is to examine individual and community factors associated with repeat induced abortion in Ghana which would be helpful to design appropriate programmes and policies targeted at improving the sexual and reproductive health of women. Methods We used secondary cross-sectional data from the 2017 Ghana Maternal Health Survey. The study included a weighted sample of 4917 women aged 15–49 years with a history of induced abortion. A multivariable complex sample logistic regression analysis was used to investigate individual and community factors associated with repeat induced abortion among women in Ghana. Adjusted odds ratios (AOR) with 95% confidence intervals (CI) was used to measure the association of variables. Results Of the 4917 reproductive women with a history of abortion, 34.7% have repeat induced abortion. We find that, compared to women who experience single induced abortion, women who experience repeat abortion are age 25–34 years (AOR:2.16;95%CI = 1.66–2.79) or 35–49 years (AOR:2.95;95%CI:2.18–3.99), have Middle/JHS education (AOR:1.69;95%CI = 1.25–12.27), use contraceptive at the time of conception (AOR:1.48: 95%CI = 1.03–2.14), had sexual debut before 18 years (AOR:1.57; 95%CI: 1.33–1.85) and reside in urban areas (AOR:1.29;95%CI = 1.07–1.57). On the other hand, women who reside in Central (AOR:0.68;95%CI: 0.49–0.93), Northern (AOR:0.46;95%CI:0.24–0.88), Upper West (AOR:0.24; 95%CI: 0.12–0.50) and Upper East (AOR:0.49; 95%CI = 0.24–0.99) regions were less likely to have repeat induced abortion. Conclusion The study showed that both individual and community level determinants were significantly associated with repeat induced abortion. Based on the findings, it is recommended to promote sexual and reproductive health education and more emphasis should be given to adult, those with early sexual debut, those with Middle/JHS education and those who live in urban centers.

Abstract Background The plastid is the photosynthetic organelle in plant cell, and the plastid genomes (plastomes) are generally conserved in evolution. As one of the most economically and ecologically important order of angiosperms, Poales was previously documented to exhibit great plastomic variation as an order of photoautotrophic plants. Results We acquired 93 plastomes, representing all the 16 families and 5 major clades of Poales to reveal the extent of their variation and evolutionary pattern. Extensive variation including the largest one in monocots with 225,293 bp in size, heterogeneous GC content, and a wide variety of gene duplication and loss were revealed. Moreover, rare occurrences of three inverted repeat (IR) copies in angiosperms and one IR loss were observed, accompanied by short IR (sIR) and small direct repeat (DR). Widespread structural heteroplasmy, diversified inversions, and unusual genomic rearrangements all appeared in Poales, occasionally within a single species. Extensive repeats in the plastomes were found to be positively correlated with the observed inversions and rearrangements. The variation all showed a “small-large-moderate” trend along the evolution of Poales, as well as for the sequence substitution rate. Finally, we found some positively selected genes, mainly in C4 lineages, while the closely related lineages of those experiencing gene loss tended to have undergone more relaxed purifying selection. Conclusions The variation of plastomes in Poales may be related to its successful diversification into diverse habitats and multiple photosynthetic pathway transitions. Our order-scale analyses revealed unusual evolutionary scenarios for plastomes in the photoautotrophic order of Poales and provided new insights into the plastome evolution in angiosperms as a whole.

Transposable elements (TEs) are major components of eukaryotic genomes and are implicated in a range of evolutionary processes. Yet, TE annotation and characterization remain challenging, particularly for nonspecialists, since existing pipelines are typically complicated to install, run, and extract data from. Current methods of automated TE annotation are also subject to issues that reduce overall quality, particularly (i) fragmented and overlapping TE annotations, leading to erroneous estimates of TE count and coverage, and (ii) repeat models represented by short sections of total TE length, with poor capture of 5′ and 3′ ends. To address these issues, we present Earl Grey, a fully automated TE annotation pipeline designed for user-friendly curation and annotation of TEs in eukaryotic genome assemblies. Using nine simulated genomes and an annotation of Drosophila melanogaster , we show that Earl Grey outperforms current widely used TE annotation methodologies in ameliorating the issues mentioned above while scoring highly in benchmarking for TE annotation and classification and being robust across genomic contexts. Earl Grey provides a comprehensive and fully automated TE annotation toolkit that provides researchers with paper-ready summary figures and outputs in standard formats compatible with other bioinformatics tools. Earl Grey has a modular format, with great scope for the inclusion of additional modules focused on further quality control and tailored analyses in future releases. [ABSTRACT FROM AUTHOR]

Purpose: The role of repeat resection for recurrent glioblastoma (rGB) remains equivocal. This study aims to assess the overall survival and complications rates of single or repeat resection for rGB. Methods: A single-centre retrospective review of all patients with IDH-wildtype glioblastoma managed surgically, between January 2014 and January 2022, was carried out. Patient survival and factors influencing prognosis were analysed, using Kaplan–Meier and Cox regression methods. Results: Four hundred thirty-two patients were included, of whom 329 underwent single resection, 83 had two resections and 20 patients underwent three resections. Median OS (mOS) in the cohort who underwent a single operation was 13.7 months (95% CI: 12.7–14.7 months). The mOS was observed to be extended in patients who underwent second or third-time resection, at 22.9 months and 44.7 months respectively (p < 0.001). On second operation achieving > 95% resection or residual tumour volume of < 2.25 cc was significantly associated with prolonged survival. There was no significant difference in overall complication rates between primary versus second (p = 0.973) or third-time resections (p = 0.312). The use of diffusion tensor imaging (DTI) guided resection was associated with reduced post-operative neurological deficit (RR 0.37, p = 0.002), as was use of intraoperative ultrasound (iUSS) (RR 0.45, p = 0.04). Conclusions: This study demonstrates potential prolongation of survival for rGB patients undergoing repeat resection, without significant increase in complication rates with repeat resections. Achieving a more complete repeat resection improved survival. Moreover, the use of intraoperative imaging adjuncts can maximise tumour resection, whilst minimising the risk of neurological deficit.

Peritonitis is a major cause of morbidity and technique failure in patients receiving peritoneal dialysis. Complicated peritonitis that manifests as multiple or unresolving episodes is classified as refractory, recurrent, relapsing, or repeat peritonitis, and often possesses higher risk of technique failure and mortality as well as lower complete cure rates than primary or uncomplicated episodes. While these peritonitis subtypes affect a considerable portion of PD patients, details regarding their epidemiology, pathogenesis, diagnosis, clinical sequelae, and management have not yet been fully elucidated. Improved clinical awareness and understanding of complicated peritonitis subtypes is crucial to ensure optimal management for these patients; thus, we consolidate and report the pertinent findings of recent literature on these four entities.

Purpose: Gamma Knife radiosurgery (GKRS) has emerged as an effective treatment option for trigeminal neuralgia (TN) in patients with multiple sclerosis (MS). To date, the outcomes of repeat GKRS for patients with TN and MS with recurrent pain have been investigated in a few patients. This study aims to report the outcomes and predictive factors of pain reduction for MS patients undergoing repeat GKRS for recurrent TN. Methods: Eighteen patients with MS underwent repeat GKRS for recurrent TN. A retrospective chart review and telephone interviews were conducted to determine background medical history, dosimetric data, and outcomes of the procedure. Facial pain and sensory function were evaluated using the Barrow Neurological Institute (BNI) scales. Results: Fifteen patients achieved a BNI pain score of IIIa or better, indicating pain reduction, within a median period of 21 days after repeat GKRS. The maximum dose for repeat GKRS ranged from 70 to 85 Gy. Pain recurred in 5 patients after a median period of 12 months after GKRS. Percentages of patients with pain reduction at 1, 2, 3, 5, and 7 years were 60%, 60%, 50%, 50%, and 50%, respectively. Older age at repeat GKRS predicted sustained pain reduction (P = 0.01). Seven patients developed facial sensory disturbances, which were bothersome in two patients. Conclusions: Repeat GKRS may be used as an effective treatment modality for prolonging the duration of pain reduction time in patients with MS and TN. After repeat GKRS, facial sensory disturbances are common; however, they are often not bothersome. [ABSTRACT FROM AUTHOR]

The article describes a study carried out on pupils aged 12-13 with no prior programming experience. The study examined how they learn to use loops with a fixed number of repetitions. Pupils were given a set of programming tasks to solve, without any preparatory or accompanying instruction or explanation, in a block-based visual programming environment. Pupils’ programs were analyzed to identify possible misconceptions and factors influencing them. Four misconceptions involving comprehension of the loop concept and repeat command were detected. Some of these misconceptions were found to have an impact on a pupil’s need to ask the computer to check the correctness of his/her program. Some of the changes made to tasks had an impact on the frequency of these misconceptions and could be the factors influencing them. Teachers and course book writers will be able to use the results of our research to create an appropriate curriculum. This will enable pupils to acquire and subsequently deal with misconceptions that could prevent the correct understanding of created concepts.

Objectives: To investigate the utility of repeat fetal echocardiography (FE) following a diagnosis of structural congenital heart disease (CHD) on the initial FE. We evaluated how often changes in management and counseling occurred based on subsequent FE findings and sought to determine which types of CHD were more likely to have changes in management and/or counseling based on repeat FE. Methods: This was a retrospective review of all patients who presented to our center between January 2012 and January 2019 and who had more than one FE performed for structural CHD. We reviewed consultation notes to determine whether management or counseling had changed based on FE findings at follow‐up visits. Management variables included a change in location or mode of delivery, plan for atrial septostomy, initiation of prostaglandin infusion, umbilical line placement and planned admission location (nursery vs neonatal intensive care unit). We defined a counseling change as any of the above changes in management as well as any meaningful refinements in the cardiac diagnosis that led to a change in the overall prognosis or future management. Initial diagnoses were grouped into anatomically/hemodynamically relevant subgroups. Fisher's exact test was used to assess the relationship between the initial diagnosis and changes in management. Post‐hoc pairwise comparisons were performed using Dunnett's test. Results: Between January 2012 and January 2019, 267 patients underwent 534 follow‐up FE assessments performed for structural CHD. Management change based on repeat FE occurred in 41/267 (15.4%) cases. A change in management was associated with the diagnosis made at the initial visit (P < 0.001). The proportion of cases with a management change was highest among those with an initial diagnosis of pulmonary valve abnormality/non‐critical pulmonary stenosis (4/11 (36.4%)), followed by balanced atrioventricular canal (AVC) defect (5/17 (29.4%)) and left ventricular outflow tract obstruction/aortic valve abnormality or coarctation/interrupted aortic arch (19/68 (27.9%)). No management change occurred in fetuses diagnosed with isolated ventricular septal defect (VSD), truncus arteriosus, pulmonary vein anomaly or isolated arch sidedness/branching abnormality. Compared to those with a VSD, management was significantly more likely to be changed in fetuses with a balanced AVC defect (P = 0.025) and left heart lesions (P = 0.002). Right heart lesions showed a trend towards an increased incidence of management change (P = 0.05). A counseling change based on repeat FE occurred in 108/267 (40.4%) cases. The proportion of cases with a counseling change was highest among those with an initial diagnosis of pulmonary valve abnormality/non‐critical pulmonary stenosis (8/11 (72.7%)) and hypoplastic left heart syndrome/critical aortic stenosis (5/9 (55.6%)). Conclusions: The clinical utility of follow‐up FE is associated with the type of CHD diagnosed. Follow‐up FE led to changes in management in several types of CHD, most commonly in cases with an initial diagnosis of right and left outflow obstructive lesions and balanced AVC defect. When developing programmatic protocols for the frequency of FE assessments, the type of CHD should be a major determinant, but additional studies are required to reach a consensus on how often serial FE should be performed for each type of CHD. © 2023 International Society of Ultrasound in Obstetrics and Gynecology.

The eleventh-century Indian Buddhist master Ratnākaraśānti presents a unique Yogācāra interpretation of tantric maṇḍala visualisation in the *Guhyasamājamaṇḍalavidhiṭīkā. In this text, he employs the neither-one-nor-many argument to assert that the qualities of the mind represented by the deities in the maṇḍala are neither the same nor different from the mind itself. He also provides five scenarios of meditation to explain the necessity of practising both the perfection method (pāramitānaya) and the mantra method (mantranaya) together in Mahāyāna. Ratnākaraśānti's explanation exerts a significant influence on the works of later Buddhist masters in India and Tibet, with parts of it being reused in the *Śrīherukopadeśanāmasvādhiṣṭhānakrama by Śūnyasamādhivajra (c. the eleventh century), the eighteenth chapter of the Āmnāyamañjarī by Abhayākaragupta (from the late eleventh to the twelfth century) and the tantric compendium sNgags rim chen mo by the Tibetan master Tsong kha pa Blo bzang grags pa (1357–1419). This paper explores how Ratnākaraśānti's explanation has been reused and modified in these subsequent works. While Śūnyasamādhivajra faithfully reproduced Ratnākaraśānti's Yogācāra explanation, Abhayākaragupta modified it to align with his Madhyamaka view. Abhayākaragupta in turn influenced Tsong kha pa, who accepted Abhayākaragupta's Madhyamaka modification in his works. This paper also engages with current scholarly discussions on textual reuse and the underlying reasons behind it. While Śūnyasamādhivajra and Abhayākaragupta assimilated Ratnākaraśānti's explanation without acknowledgement, Tsong kha pa quoted the text by name and acknowledged Abhayākaragupta's reuse of Ratnākaraśānti's explanation. This paper concludes by discussing the factors that determine whether the reused text is acknowledged or not, and the possible reasons behind textual reuse. [ABSTRACT FROM AUTHOR]

Introduction: Repeat-induced abortion is the termination of pregnancy for more than one time using drugs or surgical intervention before the fetus reaches the age of viability. This study aimed to estimate the pooled prevalence of repeat-induced abortion and its determinants among women in Ethiopia. Materials and methods: PubMed, HINARI and Google Scholar were systematically searched for eligible studies. A random effect model was used to estimate the pooled prevalence. The Cochrane Q-statistics and I2 tests were used to assess heterogeneity between included studies. Results: The estimated pooled prevalence of repeat-induced abortion was 30.89% (95% CI: 28.88–32.91). Alcohol consumption (POR = 3.60, 95%CI: 2.26–5.74), assuming the procedure painless (POR = 2.79, 95%CI: 1.77–4.39), no fertility awareness (POR = 3.45, 95% CI: 1.05–11.36), and women with multiple sexual partners (POR = 4.31, 95% CI: 3.36–5.53) were significantly associated with repeat-induced abortion. Conclusion: The study revealed that about one in ten women who had a history of abortion experienced repeat-induced abortion. Alcohol consumption, no fertility awareness, assuming the procedure is painless, and having multiple sexual partners were significantly associated with repeat-induced abortion.

Musa is one of the most economically important genera distributed throughout the globe. Many species of this genus are narrowly endemic to India and are used as a food source or herbal medicines by the tribal communities. One of the economically important species, Musa indandamanensis, also known as a sweet banana with orange pulp, is confined to the Andaman and Nicobar Islands (A&N) in India. In the present study, we sequenced and characterized the complete plastome of M. indandamanensis and compared it with closely allied species M. kattuvazhana and different taxa belonging to the section Musa. The plastome of M. indandamanensis is 170,207 bp long in size and depicts a typical quadripartite structure having 88,753pb long LSC, 10,820 bp long SSC, and two 35,317 bp long IRs. Moreover, it also depicted 21, 29, 11, and 3, forward, palindromic, reverse and complement repeats, respectively. It also possesses 30, 9, 7, 9, 4, 2, and 7, mono, di, tri, tetra, penta, hexa, and compound SSRs, respectively. Corroborating the previous studies, some nucleotide hotspot regions (atpH–atpI, ndhG–ndhI, and rpoB–petN and psbC–psaB) were also revealed during this comparative study. The current phylogenomic study confirmed the placement of M. indandamanensis in section Musa as a sister to M. kattuvazhana. The plastome data generated in the study would provide the baseline data for future phylogenetic studies. [ABSTRACT FROM AUTHOR]

Simple Summary: Ammannia arenaria and A. multifloras, the most common broad-leaved weeds in rice paddy fields in China, are morphologically similar at the seedling stage. However, their degree of damage to rice may vary. Furthermore, the sensitivity of two species to the constantly emerging new herbicides is also unknown. This study conducted field investigations, indoor biological experiments, and chloroplast genome construction and analysis to clarify the differences in biological characteristics, herbicide sensitivity, and chloroplast genetics between A. arenaria and A. multifloras. Our research results may provide theoretical basis for weed occurrence prediction, selection of herbicides, and Ammannia classification and distinction. Furthermore, the results provided valuable biological information on cp genomes of Ammannia that will be useful to identify and classify Ammannia, and study their phylogenetic relationships and evolution. Ammannia arenaria and A. multifloras, morphologically similar at the seedling stage, are the most common broad-leaved weeds in paddy fields. Our study showed that A. arenaria occupied more space than A. multifloras when competing with rice. However, A. multifloras germination has lower temperature adaptability. No difference in sensitivity to common herbicides between two Ammannia species was observed. Chloroplast (cp) genomes could be conducive to clarify their genetic relationship. The complete cp genome sequences of A. arenaria (158,401 bp) and A. multiflora (157,900 bp) were assembled for the first time. In A. arenaria, there were 91 simple sequence repeats, 115 long repeats, and 86 protein-encoding genes, one, sixteen, and thirty more than those in A. multiflora. Inverted repeats regions expansion and contraction and the phylogenetic tree based on cp genomes demonstrated the closely relationship between the two species. However, in A. arenaria, 20 single nucleotide polymorphisms in the CDS region were detected compared to A. multiflora, which can be used to distinguish the two species. Moreover, there was one unique gene, infA, only in A. arenaria. This study provides reliable molecular resources for future research focusing on the infrageneric taxa identification, phylogenetic resolution, population structure, and biodiversity of Ammannia species.

The effects of short‐time repeat microwave treatments on the physicochemical properties of sweet potato starch are investigated in this study. Pores appear on the surface of starch after repeat microwaves treatment, and the repeat microwave treatment for 60 s has a greater effect on the destruction of the pore size of the starch surface. Compared with the native starch, the Fourier infrared spectrum of short‐time repeat microwave treatment shows no new peaks but reduces the short‐range ordering of the starch. The short‐time repeat microwave treatment has no effect on the crystal mode of starch (A‐type), but the relative crystallinity of starch decreases. Multiple short‐time repeat microwave treatments reduce the peak viscosity of starch, but increase the water/oil holding capacity (WHC/OHC) and the particle diameter of starch. Modified starch obtained by short‐time repeat microwave treatment can be used as thickener. [ABSTRACT FROM AUTHOR]

Background and aims: Repeat hepatectomy for adult recurrent hepatocellular carcinoma significantly prolongs the overall survival, but repeat hepatectomy for pediatric recurrent hepatoblastoma (HB) is rarely reported, and the outcomes are warranted to be investigated. Methods: All patients between May 2015 and December 2020 with recurrent HB after intended surgical cure were retrospectively evaluated. Clinicopathologic features, surgical details and outcomes were analyzed during a median following-up of 24 months after repeat hepatectomy. Survival analysis was performed using the Kaplan–Meier estimate. Results: A total of 18 patients of recurrent HB undergoing repeat hepatectomy with radical cure intention were included. There were 11 males and 7 females. The median age was 29 months (range 5–87 months) at first hepatectomy, and the median time to the recurrence from the first hepatectomy was 7 months. The operating time of the repeat hepatectomy was 5.0 h (range 3.5–9.0 h) and the mean blood loss was 592 ml (range 50–3200 ml). Radical resection (R0) was achieved in 12 patients (66.7%), with a postoperative hospital stay of 7.9 ± 1.8 days. No serious postoperative complications or mortality occurred. The overall survival (OS) rate was 55.6% (10/18) and the event-free survival (EFS) rate was 33.3% (6/18). Those with no lung metastases, not high-risk stratification, and achieving R0 hepatectomy, anatomic hepatectomy had longer OS rate (all P < 0.05) after repeat hepatectomy. Two of three patients with re-recurrence HB undergoing salvage liver transplantation were alive with a tumor-free survival. Conclusions: Repeat hepatectomy for recurrent HB can be carried out safely. However, only a highly selected subgroup of patients might actually benefit from this procedure. [ABSTRACT FROM AUTHOR]

This study aims to investigate the effect of sports sponsorship activities on the buying behaviour of sports audiences, in addition to determining the statistical differences in the level of sports sponsorship activities and the buying response according to some organizational and demographic factors. The research population consists of Jordanian sports audiences who live in Amman city. The Convenience sampling technique is used. The researcher selects the respondents from coffee shops, cafes, famous malls in Amman, and social media users. The recommended sample size is 385. The unit of analysis is the Jordanian who attended and watched the sports activities for up to 19 years living in Amman. The study concludes that sports sponsorship activities strongly positively affected the buying response "ATR" of the sports audience. It is found statistically significant differences in the awareness tend to males and B.A. degree holders. It is also found that the age between 42 - 46 is the most experienced, but it is found that there are no differences between the sports audience segments in the repeated purchase stage. Finally, there is a statistically significant difference in sponsorship activities and tends to the telecom companies in Jordan. The study presents a set of recommendations that enhance the use of sponsorship in the local sports market. [ABSTRACT FROM AUTHOR]

BackgroundHospital policies restricting access to trial of labor after cesarean (TOLAC) are prevalent. Many women with a previous cesarean birth are affected by these bans, but there are limited data on the effect of these bans and whether women would consider changing delivery hospitals in the setting of a real or hypothetical TOLAC ban.MethodsThis was a survey of TOLAC-eligible women receiving prenatal care at four hospitals where TOLAC is available, and 1 non-TOLAC site. Participants were asked about their likelihood of switching hospitals to pursue TOLAC if it were unavailable. Women at the non-TOLAC site had their medical records reviewed to ascertain final location and approach to delivery.ResultsA total of 297 women were interviewed, 48 from the non-TOLAC site. 162 (54%) participants indicated they would transfer care if TOLAC were unavailable. Among women at the non-TOLAC site, 57% who indicated an intention to switch hospitals did so. In a multivariable logistic regression model, variables associated with transferring care included race/ethnicity other than Latina (aOR 25.20 [95% CI 2.23-284.26]), being unaware of the TOLAC ban (19.81 [1.99-196.64]), and perceiving that a close friend/relative thought they should undergo TOLAC (17.31 [1.70-176.06]).ConclusionsMore than half of women with prior cesarean would consider transferring care if TOLAC became unavailable, and more than 1 of 3 of women at a non-TOLAC site transferred care. More research is needed on the impact of TOLAC bans and how to facilitate transfer for those who desire TOLAC.

Reject rate analysis is considered an integral part of a diagnostic radiography quality control (QC) program. A rejected image is a patient radiograph that was not presented to a radiologist for diagnosis and that contributes unnecessary radiation dose to the patient. Reject rates that are either too high or too low may suggest systemic department shortcomings in QC mechanisms. Due to the lack of standardization, reject data often cannot be easily compared between radiography systems from different vendors. The purpose of this report is to provide guidance to help standardize data elements that are required for comprehensive reject analysis and to propose data reporting and workflows to enable an effective and comprehensive reject rate monitoring program. Essential data elements, a proposed schema for classifying reject reasons, and workflow implementation options are recommended in this task group report. [ABSTRACT FROM AUTHOR]

Objectives: To provide clinicians with concrete solutions on the best management of and counseling for patients in a subsequent pregnancy following uterine rupture. Methods: A retrospective analysis of patients treated between 2005 and 2020 at Sheba Medical Center was conducted. All patients who had undergone a complete uterine rupture and subsequently had a full‐term pregnancy were included. A literature review was conducted using Pubmed database and including previously published literature reviews. Results: Fifteen patients with subsequent pregnancies following uterine rupture were included in our cohort. Mean interval between rupture and subsequent pregnancy was 3.8 years (range 2.2–6.9 years). One patient had repeat uterine rupture of less than 2 cm at 36+5 weeksof pregnancy. A total of 17 studies were selected in this literature review, including a total of 774 pregnancies in 635 patients. The risk of repeated uterine rupture was 8.0% (62/774), ranging from 0% to 37.5%. Overall, the risk of maternal death was of 0.6% (4/635), with only four cases reported in three studies. Conclusion: The risk of recurrence after uterine rupture is significant but should not prevent patients from conceiving. Synopsis: This case series and review contributed to define a practical strategy in aiding clinicians to deal with this delicate and rare setting. [ABSTRACT FROM AUTHOR]

This study examines the extent and time course of repeat missing incidents involving children. Using data from one UK police force (n = 2,251), we find (1) that the majority (65%) of missing incidents are repeats, (2) that a small group of repeatedly missing children (n = 43; 6%) account for a sizable proportion of all missing incidents (n=739, 33%) and (3) that the likelihood of a child going missing repeatedly is elevated in the weeks immediately following a previous missing incident. The implications of our findings for future research and for the prevention of missing incidents are discussed. [ABSTRACT FROM AUTHOR]

Background: Non-pulmonary vein (PV) triggers play a role in the initiation of atrial fibrillation (AF), with the superior vena cava (SVC) being a common location. The aim of the current study was to investigate a strategy of empirical SVC isolation (SVCI) in addition to re-isolation of PV in patients with recurrence of AF after index PV isolation (PVI). Methods: We retrospectively analyzed consecutive patients from two centers with recurrence of AF after index PVI, undergoing a repeat ablation. Whereas only a re-isolation of the PV was intended in patients with reconnections of equal or more than two PV (PVI group), an additional SVCI was aimed for in patients with < 2 isolated PV in addition to the re-isolation of the PV (PVI + group). Analysis was performed as-treated and per-protocol. Results: Of the 344 patients included in the study (age 60 ± 10 years, 73% male, 66% paroxysmal AF), PVI only was performed in 269 patients (77%) and PVI plus SVCI (PVI +) in 75 patients (23%). Overall, freedom from AF/AT after repeat PVI was 80% (196 patients) in the PVI group and 73% in the PVI + group (p = 0.151). In multivariable Cox regression analysis, presence of persistent AF (HR 2.067 (95% CI 1.389–3.078), p < 0.001) and hypertension (HR 1.905 (95% CI 1.218–2.980), p = 0.005) were identified as only significant predictors of AF/AT recurrence. The per-protocol results did not differ from this observation. Conclusions: A strategy of an empirical additional SVCI at repeat PVI ablation for recurrence of AF/AT does not improve outcome compared to a PVI only approach. [ABSTRACT FROM AUTHOR]

Background: Vertical Paramedian Hemispherotomy (VPH) is considered an effective surgical treatment for drug-resistant epilepsy with 80% of patients experiencing seizure freedom or worthwhile improvement. Identifying persistent connective tracts is challenging in failed VPH. Methods: We reviewed our series of consecutive patients undergoing VPH for hemispheric drug-resistant epilepsy and included cases with recurrent epileptic seizures undergoing second surgery with at least 6 months of postoperative follow-up. The cases were extensively assessed to propose a targeted complementary resection. Results: Two children suffering from seizure recurrence following hemispherotomy leading to second surgery were included. After complete assessment, persisting amygdala residue was suspected responsible for the epilepsy recurrence in both patients. Complementary resection of the amygdala residue led to seizure freedom for both patients (Engel IA/ILAE Class 1) without complication. Different diagnostic tools are used to assess patients after failed hemispherotomy including routine EEG, prolonged video EEG, MRI (particularly DTI sequences), SPECT or PET scans and clinical evaluation. These tools allow to rule out epileptic foci in the contralateral hemisphere and to localize a potentially persisting epileptogenic zone. Assessment of these patients should be as systematic and integrated as the initial workup. Although our two patients suffered from Rasmussen's encephalitis, seizure recurrence after VPH has been described in other pathologies. Conclusion: Lying deep and medially in the surgical corridor of VPH, the amygdala can be incompletely resected and cause recurrent epilepsy. Complementary selective resection of the amygdala residue may safely lead to success in epilepsy control.

Combustion tests were conducted to investigate the high-frequency combustion instability of liquid propellant rocket engines using a small experimental model. The model simulates the base space around the propellant injectors of rocket engines. In this study, we presumed that off-design combustion occurred in the base space created by the injected propellants and injector faceplate, and investigated the propagation and repetition of combustion in the base space. The model has two base spaces in which the propagation of combustion was examined. 2-Propanol and gaseous oxygen were used as propellants. 2-Propanol was used as a substitute fuel to study the injection and combustion dynamics of high-density rocket propellants. The test results revealed that (1) the pressure changed up to 20 times higher than the pressure prior to combustion within a millisecond; (2) the flame propagated from one base space to another; (3) combustion was repeated several times, and (4) the pressure outside the base space was dozens of percent to several times greater. The propagated and repeated combustions, as in (2) and (3), can produce a pressure change of a higher frequency than the frequency due to a single combustion. The experimental results indicated that off-design combustion in the base space could be a mechanism for high-frequency combustion instability. • Propanol–oxygen combustion testing to study the rocket engine high-frequency instability. • Off-design combustion progressed in the base space created by the propellant jets and the faceplate. • Quick and large-amplitude pressure changes with combustion propagation and repetition.

Background: Faecal Immunochemical tests (FITs) in the assessment of patients presenting with symptoms have generally used a single sample. Little evidence pertains to the use of replicate, where a number of tests are done prior to decision-making or repeat FIT, where additional FIT are performed following clinical decision-making. Overwhelmingly, research has focussed on FIT to help identify colorectal cancer (CRC). The aim of this review is to assess the available literature concerning replicate and repeat FIT in symptomatic patients to help generate consensus and guide future research. Methods: The terms 'faecal immunochemical test' or 'FIT' were combined with 'multiple' or 'repeat'. EMBASE, Medline and PubMed database and other searches were conducted. All papers published in English were included with no exclusion date limits until November 2021. Results: Of the 161 initial papers screened, seven were included for review. Qualitative and quantitative FIT outcomes were assessed in the studies. The primary aims of most related to whether replicate FIT increased diagnostic yield of CRC, with colonoscopy used as the reference standard. One publication assessed the impact of a new COVID-adapted pathway on CRC detection. No consensus on replicate FIT was apparent. Some concluded that FITs may help minimise missed CRC diagnoses: others showed no increase in diagnostic yield of CRC. Conclusions: Current evidence on replicate and repeat FIT is both minimal and conflicting. FIT is a superb clinical tool, but significant gaps surrounding application remain. Further studies relating to replicate and repeat FIT are required. [ABSTRACT FROM AUTHOR]

Aim: The faecal immunochemical test (FIT) for faecal haemoglobin (f‐Hb) helps determine the risk of colorectal cancer (CRC) and has been integrated into symptomatic referral pathways. 'Safety netting' advice includes considering referral for persistent symptoms, but no published data exists on repeated FITs. We aimed to examine the prevalence of serial FITs in primary care and CRC risk in these patients. Method: A multicentre, retrospective, observational study was conducted of patients with two or more consecutive f‐Hb results within a year from three Scottish Health Boards which utilize FIT in primary care. Cancer registry data ensured identification of CRC cases. Results: Overall, 135 396 FIT results were reviewed, of which 12 359 were serial results reported within 12 months (9.1%), derived from 5761 patients. Of these, 42 (0.7%) were diagnosed with CRC. A total of 3487 (60.5%) patients had two f‐Hb < 10 μg/g, 944 (16.4%) had f‐Hb ≥ 10 μg/g followed by <10 μg/g, 704 (12.2%) f‐Hb < 10 μg/g followed by ≥10 μg/g and 626 (10.9%) had two f‐Hb ≥ 10 μg/g. The CRC rate in each group was 0.1%, 0.4%, 1.4% and 4.0%, respectively. Seven hundred and thirty four patients submitted more than two FITs within a year. The likelihood of one or more f‐Hb ≥ 10 μg/g rose from 40.4% with two samples to 100% with six, while the CRC rate fell from 0.8% to 0%. Conclusion: Serial FITs within a year account for 9.1% of all results in our Boards. CRC prevalence amongst symptomatic patients with serial FIT is lower than in single‐FIT cohorts. Performing two FITs within a year for patients with persistent symptoms effectively acts as a safety net, while performing more than two within this timeframe is unlikely to be beneficial.

Aims: The current Monkeypox virus (MPX) outbreak is not only the largest known outbreak to date caused by a strain belonging to the West‐African clade, but also results in remarkably different clinical and epidemiological features compared to previous outbreaks of this virus. Here, we consider the possibility that mutations in the viral genome may be responsible for its changed characteristics. Methods and Results: Six genome sequences of isolates from the current outbreak were compared to five genomes of isolates from the 2017 outbreak in Nigeria and to two historic genomes, all belonging to the West‐African clade. We report differences that are consistently present in the 2022 isolates but not in the others. Although some variation in repeat units was observed, only two were consistently found in the 2022 genomes only, and these were located in intergenic regions. A total of 55 single nucleotide polymorphisms were consistently present in the 2022 isolates compared to the 2017 isolates. Of these, 25 caused an amino acid substitution in a predicted protein. Conclusions: The nature of the substitution and the annotation of the affected protein identified potential candidates that might affect the virulence of the virus. These included the viral DNA helicase and transcription factors. Significance: This bioinformatic analysis provides guidance for wet‐lab research to identify changed properties of the MPX.

Background: Children with hen's egg (HE) allergy and a positive initial oral food challenge (OFC) require rechallenge to assess for tolerance. However, the risk factors for a positive repeat OFC remain unclear. Methods: We retrospectively analyzed data from 243 preschool children who failed an initial OFC with half a heated HE and repeated the same OFC after 6–24 months. Logistic regression models were used to determine risk factors for a positive repeat OFC, including factors that were ascertainable immediately after the initial OFC and at the repeat OFC as variables. Results: The median age, egg white‐, and ovomucoid‐specific IgE (sIgE) were 3.5 years, 12.7, and 7.2 kUA/L, respectively. The median interval between OFCs was 12.4 months and repeat OFCs were positive in 132 (54%) patients. One multivariate analysis model indicated that risk factors for a positive repeat OFC included cumulative dose (adjusted odds ratio [aOR]:0.58), anaphylaxis (aOR: 3.09), total serum IgE (aOR: 0.41), ovomucoid‐sIgE (aOR: 3.21), and age (aOR: 1.68) at the initial OFC. Another model indicated that the risk factors were cumulative dose (aOR: 0.59) and anaphylaxis (aOR: 3.41) at initial OFC and total serum IgE (aOR: 0.36), ovomucoid‐sIgE (aOR: 4.93), and age (aOR: 1.30) at repeat OFC. Conclusion: Low threshold dose and severe symptoms at initial OFC, and low total serum IgE, high ovomucoid‐sIgE and higher age at initial and repeat OFCs are risk factors for the persistence of HE allergy and they may be useful when deciding the rechallenge interval for heated HE in preschool children.

Quercus ningangensis is an economically and ecologically important tree species belonging to the family Fagaceae. In this study, the complete chloroplast (cp) genome of Q. ningangensis was sequenced and assembled, and 18 published cp genomes of Quercus were retrieved for genomic analyses (including sequence divergence, repeat elements, and structure) and phylogenetic inference. With this study, we found that complete cp genomes in Quercus are conserved, and we discovered a codon composition bias, which may be related to genomic content and genetic characteristics. In addition, we detected considerable structural variations in the expansion and contraction of inverted repeat regions. Six regions with relatively high variable ( matK-rps16 , psbC , ycf3 intron, rbcL , petA-psbJ , and ycf1 ) were detected by conducting a sliding window analysis, which has a high potential for developing effective genetic markers. Phylogenetic analysis based on Bayesian inference and maximum likelihood methods resulted in a robust phylogenetic tree of Quercus with high resolution for nearly all identified nodes. The phylogenetic relationships showed that the phylogenetic position of Q. ningangensis was located between Q. sichourensis and Q. acuta . The results of this study contribute to future research into the phylogenetic evolution of Quercus section Cyclobalanopsis ( Fagaceae ).

Echinochloa crus-galli var. crus-galli, E. crus-galli var. zelayensis, and E. glabrescens, morphologically similar at the seedling stage, are the most pernicious barnyard grass species in paddy fields worldwide. Chloroplast (cp) genomes could be conducive to their identification. In this study, we assembled the complete cp genome sequences of Echinochloa crus-galli var. crus-galli (139,856 bp), E. crus-galli var. zelayensis (139,874 bp), and E. glabrescens (139,874 bp), which exhibited a typical circular tetramerous structure, large and small single-copy regions, and a pair of inverted repeats. In Echinochloa crus-galli var. crus-galli, there were 136 simple sequence (SSRs) and 62 long (LRs) repeats, and in the other two species, 139 SSRs and 68 LRs. Each cp genome contains 92 protein-encoding genes. In Echinochloa crus-galli var. crus-galli and E. glabrescens, 321 and 1 single-nucleotide polymorphisms were detected compared to Echinochloa crus-galli var. zelayensis. IR expansion and contraction revealed small differences between the three species. The phylogenetic tree based on cp genomes demonstrated the phylogenetic relationship between ten barnyard grass species and other common Gramineae plants, showing new genetic relationships of the genus Echinochloa. This study provides valuable information on cp genomes, useful for identifying and classifying the genus Echinochloa and studying its phylogenetic relationships and evolution. [ABSTRACT FROM AUTHOR]

Awake craniotomy is used for addressing lesions adjacent to eloquent brain regions to minimize damage to neurological functions, and to expedite postoperative recovery. Redo (i.e., repeat) awake surgery is not common, but always an option, especially for recurrent tumors. This study investigated the tolerability of redo awake surgery in terms of surgical characteristics and postoperative clinical course. Single-institution cohort study of 607 awake craniotomies by 1 surgeon at Toronto Western Hospital, 2006–2018. Out of 607 surgeries, 501 surgeries were first-time, and 106 surgeries were redo. Between the 2 groups, surgery time was longer in redo cases than first-time cases and the rate of reoperation was higher in the former. Matched propensity cohort analysis included 104 cases each, based on adjustments for age, sex, tumor location, malignancy, and preoperative performance status. This revealed differences again in surgery time (128.0 vs. 111.9 minutes, P = 0.0004) and the reoperation rate (7.4 vs. 1.0%, P = 0.03). The causes of reoperation were infection (3 wound infection and 3 brain abscess) and wound dehiscence (n = 1). There was no significant difference in the length of hospital stay, the rates of postoperative hemorrhage, new postoperative neurological deficits, home discharge, or readmission. Although redo surgery might increase the surgery time and the risk of reoperation due to postoperative infection, it was found to be well tolerated in other aspects overall. With extra care to infection and wound healing, redo awake surgery is a viable option to patients with the same surgical indication as for first-time surgery. [ABSTRACT FROM AUTHOR]

The extreme diversity and complexity of angiosperms is well known. Despite the fact that parasitic plants are angiosperms, little is known about parasitic plant mitogenomic diversity, complexity, and evolution. In this study, we obtained and characterized the mitogenomes of three Cistanche species (holoparasitic plants) from China to compare the repeats, segment duplication and multi-copy protein-coding genes (PCGs), to clarify the phylogenetic and evolution relationship within the Lamiales order, and to identify the mitochondrial plastid insertions (MTPT) in Cistanche mitogenomes. The results showed that the mitogenome sizes of the three Cistanche species ranged from 1,708,661 to 3,978,341 bp. The Cistanche species genome encodes 75–126 genes, including 37–65 PCGs, 31–58 tRNA genes and 3–5 rRNA genes. Compared with other Lamiales and parasitic species, the Cistanche species showed extremely high rates of multi-copy PCGs, ranging from 0.13 to 0.58 percent of the total number of PCGs. In addition, 37–133 Simple Sequence Repeat (SSRs) were found in these three mitogenomes, the majority of which were the mononucleotides Adenine/Thymine. The interspersed repeats contained forward and palindromic repeats. Furthermore, the segment-duplication sequence size ranged from 199,584 to 2,142,551 bp, accounting for 24.9%, 11.7% and 53.9% of the Cistanche deserticola, Cistanche salsa and Cistanche tubulosa mitogenome, respectively. Furthermore, the Ka/Ks analysis suggested that the atp4, ccmB, ccmFc and matR were probably positively selected during Lamiales evolution. The Cistanche plastome suggested the presence of MTPT. Moreover, 6–12 tRNA, 9–15 PCGs fragments and 3 rRNA gene fragments in the Cistanche mitogenomes were found in the MTPT regions. This work reports the Cistanche species mitogenome for the first time, which will be invaluable for study the mitogenome evolution of Orobanchaceae family. [ABSTRACT FROM AUTHOR]

Background: Regarding the newly diagnosed vestibular schwannomas (VSs), active surveillance, microsurgical resection (MS), and stereotactic radiosurgery (SRS) are the leading treatment options. Although SRS is an effective intervention with a low incidence of complications, failure may occur occasionally. Several options, including repeat SRS, are considered salvage treatment after failure of the SRS. In this systematic review and meta-analysis study, we aimed to evaluate the efficacy and outcomes of repeat stereotactic radiosurgery (SRS) in progressive VS following the failure of the initial SRS., Method: The electronic databases of PubMed/Medline, Scopus, Embase, and Web of Science (WOS) were searched from inception to August 23rd, 2024. Studies that evaluated the role of repeat SRS in the setting of VS were included. The risk of bias was assessed using the Risk of Bias in Non-Randomized Studies of Interventions tool. The R program performed the meta-analyses, sensitivity analysis, publication bias, and meta-regression., Results: A total of 11 studies encompassing 260 VS patients with repeat SRS were included in our study. The median time interval between initial and repeat SRSs ranged from tumor volume ranged from 43 to 62 months. Our analysis revealed a pooled tumor control of 91 % (95 % CI: 86 %-94 %). Regarding the radiological response, the pooled regression rate was 59 % (95 % CI: 52 %- 65 %), while the pooled progression rate was 9 % (95 % CI: 6 %- 14 %). Regarding the clinical outcomes, the pooled serviceable hearing preservation (SHP) rate was 36 % (95 % CI: 22 %-53 %), while worsened fifth cranial nerve (CN) and seventh CN rates were 12 % (95 % CI: 7 %- 19 %) and 8 % (95 % CI: 5 %- 12 %), respectively. In addition, the pooled adverse radiation effect (ARE) rate was 6 % (95 % CI: 3 %- 11 %)., Conclusion: Our results suggest that the repeat SRS following the failure of the initial SRS in VS is associated with favorable outcomes, including tumor control, SHP, and CN worsening concurrent with low ARE rates., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

The pandemic of corona virus disease 2019 (COVID-19) caused by SARS-CoV-2 is ravaging the world. Diagnosis and isolation of persons who are infected with SARS-CoV-2 is very important medical emergency to contain the epidemic of COVID-19. To date, the diagnosis of COVID-19 is mainly depending on positive quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) results for SARS-CoV-2. In the present study, we reported that two cases with uncommon symptoms from a family cluster were ultimately diagnosed as COVID-19 after more than twice of collecting samples and qRT-PCR tests were done. It is easily to miss diagnosis of COVID-19 especially for patients with uncommon symptoms. More attention should be paid to observe the clinical characteristics of it and invent more accurate and convenient methods to detect SARS-CoV-2 as soon as possible.

Ammannia arenaria and A. multifloras, morphologically similar at the seedling stage, are the most common broad-leaved weeds in paddy fields. Our study showed that A. arenaria occupied more space than A. multifloras when competing with rice. However, A. multifloras germination has lower temperature adaptability. No difference in sensitivity to common herbicides between two Ammannia species was observed. Chloroplast (cp) genomes could be conducive to clarify their genetic relationship. The complete cp genome sequences of A. arenaria (158,401 bp) and A. multiflora (157,900 bp) were assembled for the first time. In A. arenaria, there were 91 simple sequence repeats, 115 long repeats, and 86 protein-encoding genes, one, sixteen, and thirty more than those in A. multiflora. Inverted repeats regions expansion and contraction and the phylogenetic tree based on cp genomes demonstrated the closely relationship between the two species. However, in A. arenaria, 20 single nucleotide polymorphisms in the CDS region were detected compared to A. multiflora, which can be used to distinguish the two species. Moreover, there was one unique gene, infA, only in A. arenaria. This study provides reliable molecular resources for future research focusing on the infrageneric taxa identification, phylogenetic resolution, population structure, and biodiversity of Ammannia species.

Hemp (Cannabis sativa L., 2n = 20) is a valuable crop that is successfully used as a food, technical and medicinal crop. It is a dioecious plant with an XX\XY sex determination system. Some chromosomes of C. sativa have almost the same lengths and centromeric indexes. Cytogenetic markers help to distinguish similar plant chromosomes, including sex chromosomes, which is important for the breeding process. Two repeats (CS-1 and CS-237) were used to develop labeled oligo-probes for rapid and low-cost oligo-FISH. These oligos can be recommended for use as cytological markers to distinguish sex chromosomes (X and Y) and somatic chromosome pairs 3, 6, and 8 by rapid oligo-FISH in a short time.

Olduvai protein domains (also known as DUF1220 or NBPF) have undergone the greatest human-specific increase in the copy number of any coding region in the genome. Their repeat number was strongly associated with the evolutionary expansion of brain volumes, neuron counts and cognitive abilities, as well as with disorders of the autistic spectrum. Nevertheless, the domain function and cellular mechanisms underlying the positive selection of Olduvai DNA sequences in higher primates remain obscure. Here, I show that the inclusion of Olduvai exon doublets in mature transcripts is facilitated by a potent splicing enhancer that was created through duplication within the first exon. The enhancer is the strongest among the NBPF transcripts and further promotes the already high splicing activity of the unexpanded first exons of the two-exon domains, safeguarding the expanded Olduvai exon doublets in the mature transcriptome. The duplication also creates a predicted RNA guanine quadruplex that may regulate the access to spliceosomal components of the super-enhancer and influence the splicing of adjacent exons. Thus, positive Olduvai selection during primate evolution is likely to result from a combination of multiple targets in gene expression pathways, including RNA splicing. [ABSTRACT FROM AUTHOR]

Background: Women who have previously had a caesarean section often face the choice between planning for a vaginal birth after caesarean (VBAC) or an elective repeat caesarean section (CS) for future pregnancies. Informing a woman of her individualised chance of a successful VBAC can aid her decision making. Aims: The aim is to create two VBAC prediction models using an Australian cohort – one for use in labour when labour variables are known, and one for use antenatally when labour characteristics are unknown. Materials and Methods: This study was a retrospective analysis of perinatal data in Victoria, Australia, over a 10‐year period. During this time, 22 062 women were recorded as attempting a VBAC with a term singleton live birth. The data were separated into three parts. A 'training set' was used to build the complete VBAC prediction model and the antenatal VBAC prediction model using multivariate logistic regression. The models were then adjusted to only include the variables that contributed to model performance. The models were validated by testing the receiver operating characteristic (ROC) area under the curve within the 'validation set'. Then the models were tested for accuracy within the 'test set'. Results: Using a 'test set' of data, the models demonstrated an area under the ROC curve of 0.7887 and 0.7384 for the complete and antenatal models respectively, showing adequate performance of both models. Conclusions: With these models, Australian women can be counselled about their predicted chance of VBAC success. [ABSTRACT FROM AUTHOR]

Abstract Background Local treatment remains the best option for recurrent colorectal liver metastasis (CRLM). The current study aimed to investigate predictive factors of survival outcomes and select candidates for local treatment for CRLM at first recurrence. Methods Data were collected retrospectively from CRLM patients who underwent hepatic resection and developed first recurrence between 2000 and 2019 at our institution. A nomogram predicting overall survival was established based on a multivariable Cox model of clinicopathologic factors. The predictive accuracy and discriminative ability of the nomogram were determined by the concordance index and calibration curve. Results Among 867 patients who underwent curative hepatic resection, 549 patients developed recurrence. Three hundred patients were evaluated and had resectable and liver-limited disease. Among them, repeat liver resection and percutaneous radiofrequency ablation were performed in 88 and 85 patients, respectively. The other 127 patients received only systemic chemotherapy. Multivariable analysis identified primary lymph node positivity, tumor size > 3 cm, early recurrence, RAS gene mutation and no local treatment as independent risk factors for survival outcomes. Integrating these five variables, the nomogram presented a good concordance index of 0.707. Compared with patients who received only systemic chemotherapy, radical local treatment did not significantly improve survival outcomes (median OS: 21 vs. 15 months, p = 0.126) in the high-risk group (total score ≥ 13). Conclusion Radical local treatment improved the survival of recurrent CRLM patients. The proposed model facilitates personalized assessments of prognosis for patients who develop first recurrence in the liver.

Objective: With increased focus on surgical management of the eustachian tube, clarifying management decisions benefits patients and surgeons. In this study, we examine the value of repeating the balloon dilation of the eustachian tube (BDET) procedure in patients who did not improve after the initial BDET. Study Design: Level IV retrospective review of 145 BDETs performed on 86 patients between January 1, 2014, and May 1, 2019, identified 10 patients who underwent BDET more than once. Setting: Managed care community otolaryngology practice. Methods: Demographic and outcome data were collected on both single and repeat BDET cohorts. Results: The Eustachian Tube Dysfunction Questionnaire 7 (ETDQ-7) was used as the primary outcome measure when comparing single vs repeat BDET cohorts. Generally, the 2 cohorts were similar in terms of sex and age distribution. Tobacco use and radioallergosorbent test–positive results were greater proportionally in the repeat BDET cohort. Preoperative ETDQ-7 scores were similar in both cohorts. Single BDET patients overall showed significant improvement in ETDQ-7 scores. ETDQ-7 scores for repeat BDET patients who did not improve after the first procedure similarly did not demonstrate improvement after the second procedure. Conclusions: Inevitably, some patients will not improve after an initial BDET procedure. The utility of a repeated BDET procedure should be considered in determining how to manage such failures. The results of this limited study suggest that patients who fail to improve meaningfully on ETDQ-7 scores after the initial procedure are unlikely to show substantial improvements after a repeated procedure.

The order Boletales is a group of fungi with complex life styles, which include saprophytic and ectomycorrhizal mushroom-forming fungi. In the present study, the complete mitogenomes of two saprophytic Boletales species, Coniophora olivacea, and C. puteana, were assembled and compared with mitogenomes of ectomycorrhizal Boletales. Both mitogenomes comprised circular DNA molecules with sizes of 78,350 bp and 79,655 bp, respectively. Comparative mitogenomic analysis indicated that the two saprophytic Boletales species contained more plasmid-derived (7 on average) and unknown functional genes (12 on average) than the four ectomycorrhizal Boletales species previously reported. In addition, the core protein coding genes, nad2 and rps3, were found to be subjected to positive selection pressure between some Boletales species. Frequent intron gain/loss events were detected in Boletales and Basidiomycetes, and several novel intron classes were found in two Coniophora species. A total of 33 introns were detected in C. olivacea, and most were found to have undergone contraction in the C. olivacea mitogenome. Mitochondrial genes of Coniophora species were found to have undergone large-scale gene rearrangements, and the accumulation of intra-genomic repeats in the mitogenome was considered as one of the main contributing factors. Based on combined mitochondrial gene sets, we obtained a well-supported phylogenetic tree for 76 Basidiomycetes, demonstrating the utility of mitochondrial gene analysis for inferring Basidiomycetes phylogeny. The study served as the first report on the mitogenomes of the family Coniophorineae, which will help to understand the origin and evolution patterns of Boletales species with complex lifestyles.
