Abstract

Background: The literature is inconclusive when comparing health-related quality of life following restorative anterior resection (AR) compared with abdominoperineal resection (APR). Consideration of functional outcomes may explain this inconsistency. The aim of this study was to compare health-related quality of life in patients post-anterior resection, stratified by low anterior resection syndrome score, and post-abdominoperineal resection patients. Methods: A cross-sectional study of consecutive patients post APR and AR for rectal or sigmoid adenocarcinoma at a tertiary centre in Sydney, Australia (Jan 2012- Dec 2021) was performed. HRQoL outcomes (SF36v2 physical [PCS] and mental component summary [MCS] scores) were compared between APR and AR patients, with subgroup analyses stratifying AR patients according to LARS score (no/minor/major). Age- and gender-adjusted comparisons were performed by linear regression. Results: Overall, 248 post-AR patients (57.3% male, mean age 70.8 years, SD 11.6) and 64 post-APR patients (62.5% male, mean age 68.1 years, SD 13.1) participated. When stratified by LARS, 'major LARS' had a similar negative effect on age-and sex-adjusted PCS scores as APR. 'No LARS' (p < 0.001) and 'minor LARS' (p < 0.001) patients had higher PCS scores compared to post-APR patients. 'Major LARS' had a similarly negative effect on MCS scores compared with post-APR patients. MCS scores were higher in 'no LARS' (p = 0.006) compared with APR patients. Conclusions: Postoperative bowel dysfunction significantly impacts health-related quality of life. Patients with 'major LARS' have health-related quality of life as poor as those following APR. This requires consideration when counselling patients on postoperative health-related quality of life, especially where poor postoperative bowel function is anticipated following restorative surgery.

Abstract

Genetic alterations in signaling pathways that control cell-cycle progression, apoptosis, and cell growth are common hallmarks of cancer, but the extent, mechanisms, and co-occurrence of alterations in these pathways differ between individual tumors and tumor types. Using mutations, copy-number changes, mRNA expression, gene fusions and DNA methylation in 9,125 tumors profiled by The Cancer Genome Atlas (TCGA), we analyzed the mechanisms and patterns of somatic alterations in ten canonical pathways: cell cycle, Hippo, Myc, Notch, Nrf2, PI-3-Kinase/Akt, RTK-RAS, TGFβ signaling, p53 and β-catenin/Wnt. We charted the detailed landscape of pathway alterations in 33 cancer types, stratified into 64 subtypes, and identified patterns of co-occurrence and mutual exclusivity. Eighty-nine percent of tumors had at least one driver alteration in these pathways, and 57% percent of tumors had at least one alteration potentially targetable by currently available drugs. Thirty percent of tumors had multiple targetable alterations, indicating opportunities for combination therapy. An integrated analysis of genetic alterations in 10 signaling pathways in >9,000 tumors profiled by TCGA highlights significant representation of individual and co-occurring actionable alterations in these pathways, suggesting opportunities for targeted and combination therapies.

Abstract

We describe 3 cases of omental lipoma of whom 2 presented with symptomatic haemorrhage. Notably the haemorrhage in the 2 reported cases was from foregut arteries. Thorough knowledge of anatomy and embryology is critical in identifying the source of haemorrhage and differentiating this condition from other common causes of mesenteric haemorrhage. To the best of our knowledge, this is the first case series reporting this uncommon cause for abdominal haemorrhage. The successful management of this condition using superselective embolization is discussed. Clinicians need to exercise diligence and caution in omental lipomas presenting with spontaneous haemorrhage and this notion is exemplified in our reported cases.

Abstract

In this paper, we present an integration preconditioning method to solve multi-asset option pricing problems modelled by the well-known Black-Scholes equation. This integration preconditioning technique helps transform the partial differential equations into integral equations and contribute to a well-conditioned system. It benefits the calculation from avoiding the ill-posedness of numerical derivatives approximation in solving problems modelled by partial differential equations. Two kinds of interpolation approximations: quadrature formulas and radial basis functions (RBFs) are adopted. The integration preconditioning method improves both the accuracy and stability when compared with the traditional direct differential methods. Besides, while combining with the integral operator, the RBFs are more free to select the value of shape parameters. All the introduced benefits are investigated and verified by numerical results.

Abstract

Aim: Fistula‐in‐ano (FIA) is associated with high treatment costs and has a deleterious impact on quality of life. A wide range of healing, incontinence and recurrence rates have been reported. This study aimed to identify operative, patient and disease factors that influence these outcomes after surgery for FIA. Method: An observational cohort study of consecutive patients who were managed for FIA at a tertiary colorectal practice (1999–2019) was performed. Outcome measures included healing, impaired continence and the need to reoperate. Clinico‐pathological variables, including patient comorbidities, fistula anatomy and operative approach, were assessed for their association with these outcomes. Results: Some 411 procedures were performed on 263 patients [median age 41.8 years (range 17.8–79.7 years), 184 men (70.0%)]. Some 77.9% of patients achieved complete healing, 9.5% experienced some deterioration in continence postoperatively and 37.6% required reoperation at a median time of 19.0 weeks. Poorer healing was associated with Crohn's disease, high trans‐sphincteric fistulas, extrasphincteric fistulas and steroid usage. Poorer continence was associated with female sex, age > 40 years, posterior location, suprasphincteric fistulas, seton insertion and having more than three subsequent procedures. The need to reoperate was associated with female sex, high trans‐sphincteric fistulas, suprasphincteric fistulas, inflammatory bowel disease and previous operations for FIA. Conclusion: Minimizing recurrence of FIA and preservation of continence can be competing management goals. More than one in three patients require reoperation, one in five fails to heal completely and one in ten suffers worsened continence following surgery. Awareness of the factors that contribute to these outcomes is important to the process of informed consent and managing patient expectations before surgery. [ABSTRACT FROM AUTHOR]

Abstract

Aim: Bowel dysfunction following anterior resection (AR) is termed low anterior resection syndrome. It is unclear whether such dysfunction occurs following other bowel/pelvic operations as well. This study aimed to characterize and compare bowel dysfunction following AR, right hemicolectomy (RH) and radical cystectomy (RC). Method: A prospective study of consecutive patients undergoing AR, RH and RC (2002–2012) was performed at a tertiary referral centre in Sydney, Australia. Outcome measures included (i) patient‐reported satisfaction with bowel function, self‐described bowel function and self‐reported change in bowel function; (ii) objective assessment of bowel function using validated criteria to identify symptoms and stratify patients into those with constipation and/or faecal incontinence (FI); and (iii) health‐related quality of life (SF‐36v2 Health Survey). Results: Of 743 eligible patients, 70% participated [AR, n = 338, mean age 69.6 years (SD 11.9), 59% men; RH, n = 150, 75.8 years (SD 10.5), 54% men; RC, n = 34, 71.1 years (SD 14.1), 71% men]. AR patients were three times more likely to report change in bowel function post‐surgery and self‐judged their bowel function as abnormal more frequently (64%) than RH patients (35%) and RC patients (35%) (P < 0.01). AR patients were four times more likely to meet criteria for concomitant constipation and FI. Patients with concomitant constipation and FI had lower physical and mental SF‐36v2 scores (P < 0.001). Conclusion: Bowel dysfunction occurred after RH and RC but rates were higher following AR. This suggests that low anterior resection syndrome occurs due to a direct impact of partial/complete loss of the rectum rather than just due to loss of bowel length and/or the consequence(s) of pelvic dissection.

Abstract

Background: Bowel dysfunction after anterior resection is well documented, but its pathophysiology remains poorly understood. No study has assessed whether postoperative variation in colonic transit contributes to symptoms. This study measured colonic transit using planar scintigraphy and single‐photon emission CT (SPECT)/CT in patients after anterior resection, stratified according to postoperative bowel function. Methods: Symptoms were assessed using the low anterior resection syndrome (LARS) score. Following gallium‐67 ingestion, scintigraphy was performed at predefined time points. Nine regions of interest were defined, and geometric centre (GC), percentage isotope retained, GC velocity index and colonic half‐clearance time (T½) determined. Transit parameters were compared between subgroups based on LARS score using receiver operating characteristic (ROC) curve analyses. Results: Fifty patients (37 men; median age 72·6 (range 44·4–87·7) years) underwent planar and SPECT scintigraphy. Overall, 17 patients had major and nine had minor LARS; 24 did not have LARS. There were significant differences in transit profiles between patients with major LARs and those without LARS: GCs were greater (median 5·94 (range 2·35–7·72) versus 4·30 (2·12–6·47) at 32 h; P = 0·015); the percentage retained isotope was lower (median 53·8 (range 6·5–100) versus 89·9 (38·4–100) per cent at 32 h; P = 0·002); GC velocity indices were greater (median 1·70 (range 1·18–1·92) versus 1·45 (0·98–1·80); P = 0·013); and T½ was shorter (median 38·3 (17·0–65·0) versus 57·0 (32·1–160·0) h; P = 0·003). Percentage tracer retained at 32 h best discriminated major LARS from no LARS (area under curve (AUC) 0·828). Conclusion: Patients with major LARS had accelerated colonic transit compared with those without LARS, which may help explain postoperative bowel dysfunction in this group. The percentage tracer retained at 32 h had the greatest AUC value in discriminating such patients. [ABSTRACT FROM AUTHOR]

Abstract

Chemical stabilization by cement or lime is a proven technique for improving the engineering properties of soil particularly the compressive strength. However, this cemented soil usually shows the brittle behavior or sudden failure with little or no plastic deformation. Fiber, either synthetic or natural can be added to solve this problem. This area of research is particularly important for deep soil mixing as retaining structure or foundations on stabilized soil. Early research on fiber reinforced cemented soils focuses more on the comprehensive behaviour and only little attention has been paid on the tensile behaviour. This paper aims to appraise the current development on the study of the tensile behavior of the fiber reinforced cemented soil and points out the gap of research in the conclusion.

Abstract

The deformable image registration is a medical imaging device which is used to assess the change of tumor and adjust the target region in radiotherapy treatment. During the process of the treatment, the indispensable care is to avoid harming the surrounding health organs. On this account, the treatment location and the spatial displacements of the target area must be accurately measured, hence the side effects on healthy organs can then be reduced. This paper set up a meshless collocation scheme based on the radial basis function (RBF) to simulate the deformable image registration. The RBF method is a type of kernel based collocation method and has a meshless configuration. The method provides with a simple formulation and hence reduce time and cost used in setting up the computational region. The proposed algorithm is applied to simulate the deformable image data of a real-life liver cancer case. The performance of the numerical results is compared with two classical Demon's finite difference schemes. [ABSTRACT FROM AUTHOR]

Abstract

The source of gravitational field is stress-energy tensor. An intense laser can also generate gravitational field. We analyze the weak gravitational field of an intense pulsed of Bessel beam by solving linearized Einstein field equation. It is found that the Bessel beam generate gravitational repulsive force.

48. (Agnostic) PAC Learning Concepts in Higher-Order Logic.

Author

Fürnkranz, Johannes, Scheffer, Tobias, Spiliopoulou, Myra, and Ng, K. S.

Abstract

This paper studies the PAC and agnostic PAC learnability of some standard function classes in the learning in higher-order logic setting introduced by Lloyd et al. In particular, it is shown that the similarity between learning in higher-order logic and traditional attribute-value learning allows many results from computational learning theory to be ‘ported' to the logical setting with ease. As a direct consequence, a number of non-trivial results in the higher-order setting can be established with straightforward proofs. Our satisfyingly simple analysis provides another case for a more in-depth study and wider uptake of the proposed higher-order logic approach to symbolic machine learning. [ABSTRACT FROM AUTHOR]

50. Predicate Selection for Structural Decision Trees.

Author

Kramer, Stefan, Pfahringer, Bernhard, Ng, K. S., and Lloyd, J. W.

Abstract

We study predicate selection functions (also known as splitting rules) for structural decision trees and propose two improvements to existing schemes. The first is in classification learning, where we reconsider the use of accuracy as a predicate selection function and show that, on practical grounds, it is a better alternative to other commonly used functions. The second is in regression learning, where we consider the standard mean squared error measure and give a predicate pruning result for it. [ABSTRACT FROM AUTHOR]
