Background: This population-based cohort study aimed to evaluate occurrence of low anterior resection syndrome (LARS) and correlate this to health-related quality of life in patients who had undergone segmental colonic resection for colonic cancer in the Stockholm-Gotland region. The hypothesis was that there is a difference in occurrence of LARS depending on whether a right- or a left-sided resection was performed.

Methods: Patients who underwent segmental colonic resection for colonic cancer stages I-III in the Stockholm-Gotland region in 2013-2015 received EORTC QLQ-C30, QLQ-CR29 and LARS score questionnaires 1 year after surgery. Clinical patient and tumour data were collected from the Swedish ColoRectal Cancer Registry. Patient-reported outcome measures were analysed in relation to type of colonic resection.

Results: Questionnaires were sent to 866 patients and complete responses were provided by 517 (59·7 per cent). After right-sided resection 20·6 per cent reported major LARS. After left-sided resection the proportion with major LARS was 15·6 per cent. The odds ratio (OR) for major LARS after right-sided resection was 1·45 (95 per cent c.i. 1·02 to 2·06;  = 0·037) compared with left-sided resection. After adjustment for age and sex, an increase in the risk of major LARS after right- left-sided resection remained (OR 1·48, 1·03 to 2·13;  = 0·035). Major LARS correlated with impaired quality of life.

Conclusion: Major LARS was more frequent after right-sided than following left-sided colonic resection. Major LARS reflected impaired quality of life.

Purpose: Low anterior resection (LAR) is the preferred surgical treatment of rectosigmoid or rectal cancers. However, it is often associated with bowel dysfunction, which is termed low anterior resection syndrome (LARS). Daily bowel dysfunction symptoms have a detrimental effect on quality of life (QOL).

Introduction: Low Anterior Resection Syndrome (LARS) describes bowel dysfunction post-restorative proctectomy (RP) and is associated with poor quality of life (QoL). The aim of this study was to assess the impact of an interactive online informational and peer support App on participants' QoL (primary outcome), LARS, and emotional distress (secondary outcomes).

Methods: A multicentre, randomized, parallel-group trial was conducted across five Canadian colorectal surgery practices.

Hypoparathyroidism: Similarities and differences between Western and Eastern countries.

Osteoporos Int

Department of Endocrine and Metabolic Diseases, Shanghai Institute of Endocrine and Metabolic Diseases, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Backgroud: Hypoparathyroidism (hypoPT) is characterized by acute and chronic complications due to insufficient parathyroid hormone (PTH) production or action. Several management guidelines have been developed, but mostly based on evidence from Western countries. Data from Eastern countries have not been systematically compared with those from Western countries.

Objectives: The aim of the study was to assess the diagnosis and evolution of low anterior rectal resection syndrome (LARS) in patients admitted to a tertiary surgical center in Romania.

Materials And Methods: From 120 patients initially included in the analysis, after applying the exclusion criteria, we selected 102 patients diagnosed and operated on for neoplasm of the upper, middle, and lower rectum for which resection and excision (partial or total) of mesorectum was associated. All the patients we treated in the general surgery department of the County Emergency Hospital of Craiova within a time frame of 5 years (1 October 2017-1 September 2022), and all experienced at least one symptom associated with LARS.

Auranofin induces disulfide bond-mimicking S-Au adducts in protein thiol pairs.

J Biol Chem

January 2025

Microbial Biochemistry, Faculty of Medicine, Ruhr University Bochum, 44780 Bochum, Germany. Electronic address:

Auranofin is an inhibitor of human thioredoxin reductase, clinically used in the treatment of rheumatoid arthritis. More recently, it has been shown to possess strong antibacterial activity. Despite the structural dissimilarity and the independent evolutionary origins of human thioredoxin reductase and its bacterial counterpart (TrxB), inhibition of bacterial thioredoxin reductase is often suggested to be a major factor in auranofin's antibacterial mode of action.
