PURPOSE: Fatigue is the third most common "extraintestinal" complaint of patients with irritable bowel syndrome (IBS), but it is still poorly understood. This study aimed to review characteristics of IBS-associated fatigue and to examine pooled frequency, severity of fatigue, and correlations of related factors with fatigue in IBS via meta-analyses. METHODS: Publications were searched in eight databases from 1995 to 2014. Random effects meta-analyses were applied with standard error, weighted effect size, and correlation-based measure of effect size. RESULTS: Twenty-four studies were included in systematic review. Seventeen studies were used for meta-analyses (2 studies were excluded in the frequency of fatigue analysis due to data unavailability). Using "tiredness" to define fatigue, and Fatigue Impact Scale to assess fatigue were the most frequently used across the studies. Gastrointestinal symptoms, psychological distress, and health-related quality of life were the most common correlates with fatigue. The pooled frequency of fatigue was 54.2% [95% confidence interval (38.5, 69.4)]. Metaregression on the frequency of fatigue showed positive and significant relations with tertiary care settings, female sex, and younger age. There was a negatively moderate relationship between the severity of fatigue and health-related quality of life score (correlation-based measure of effect size: -.378). CONCLUSIONS: Fatigue is prevalent among patients with IBS and commonly co-occurs with other symptoms. This is the first study to fully examine fatigue in IBS, which shed light on the comprehensive management of fatigue in this patient group. Future research is warranted to further explore fatigue-related factors and underlying mechanisms of fatigue in IBS.

BACKGROUND: The aims of this study were to investigate the clinical characteristics of patients with combined anterior instability and superior labrum from anterior to posterior (SLAP) lesions, and to analyze the effect of concomitant SLAP repair on surgical outcomes. METHODS: We retrospectively reviewed patients who underwent arthroscopic stabilization for anterior shoulder instability between January 2004 and March 2013. A total of 120 patients were available for at least 1-year follow-up. Forty-four patients with reparable concomitant detached SLAP lesions (group I) underwent combined SLAP and anterior stabilization, and 76 patients without SLAP lesions (group II) underwent anterior stabilization alone. Patient characteristics, preoperative and postoperative pain scores, Rowe scores, and shoulder ranges of motion were compared between the 2 groups. RESULTS: Patients in group I had higher incidences of high-energy trauma (p = 0.03), worse preoperative pain visual analogue scale (VAS) (p = 0.02), and Rowe scores (p = 0.04). The postoperative pain VAS and Rowe scores improved equally in both groups without significant differences. Limitation in postoperative range of motion was similar between the groups (all p-value > 0.05). CONCLUSIONS: Anterior instability with SLAP lesion may not be related to frequent episodes of dislocation but rather to a high-energy trauma. SLAP fixation with anterior stabilization procedures did not lead to poor functional outcomes if appropriate surgical techniques were followed.

Medicine is the practice that occurs in the context of the society. It requires interaction with individual patients, fellow doctors and other health care professionals, health care officials, public, institution, and the society as a whole. To date, medical practice in Korea has largely been concentrated on applying biomedical knowledge and skill to a patient. We defines 'social competency' as 'competency for medicine as a social institution.' This survey aims to grasp the current situation of Korean doctors' perception on social competency, in terms of necessity, satisfaction, learning experience, and possible intervention. Respondents generally recognized the necessity of social competencies but were not satisfied with their demonstration of those competencies. Competencies for 'understanding on law and institution' and 'communication' were perceived highly necessary. General satisfaction and each satisfaction rate on individual competencies were all below 'neutral,' showing their dissatisfaction. Especially, doctors assess their fellow doctors' competencies for 'understanding on law and institution' and 'understanding on human being and society' at the lowest level. The mismatch between perceived necessity and satisfaction shows the legitimate ground for educational intervention. The proportions of respondents who have learned on each domain of social competency were all below 70%. Learning experience on self-management and leadership was the least. Among possible remedy for low social competency, respondents perceived 'improvement on national health insurance' and 'improvement on resident training program' as the most urgently needed. The data from this preliminary survey can be utilized for educational and institutional intervention in the future.

OBJECTIVES: This paper aims to describe an outcome-based curriculum development process at a medical school that has difficulty in advancement from the higher stage outcomes to the individual lesson outcomes, and to propose a way to implement it practically. METHODS: We reviewed the objectives, strategies and previous products of the school's taskforce activities and suggested the principle of bidirectional approaches of outcome based curriculum development. RESULTS: The developing strategy identified such as firstly, the evaluation of present curriculum and then, the review of the outcomes developed previously with considering the nation-wide environmental change in medical education. Then, we selected one example course which was focused the resources of the school to, and finally the product of the example course was propagated to the other courses with central monitoring. CONCLUSION: Bidirectional model of ‘Top-down’ plus ‘Bottom-up’ approaches could be an efficient way to develop the outcome-based curriculum in a medical school, which has difficulties to advance the developing process due to various reasons including limited resources.

BACKGROUND/AIMS: Patients with irritable bowel syndrome (IBS) often report poor sleep quality. Whether poor sleep is associated with tryptophan (Trp) metabolites is unknown. We compared serum Trp metabolites in women with IBS and healthy controls (HCs) using targeted liquid chromatography mass spectrometry (LC-MS)-based profiling. In IBS only, we explored whether Trp metabolites are associated with IBS symptoms and subjective and objective sleep indices, serum cortisol, plasma adrenocorticotropic hormone (ACTH), and cortisol/ACTH levels. METHODS: Blood samples were obtained every 80 minutes in 21 HCs and 38 IBS subjects following an anticipation-of-public-speaking stressor during a sleep laboratory protocol. Subjects completed symptom diaries for 28 days. Adjacent values of metabolites were averaged to represent 4 time-periods: awake, early sleep, mid-sleep, and mid-to-late sleep. Thirteen of 20 targeted Trp metabolites were identified. RESULTS: Ten of 13 Trp metabolites decreased across the night, while nicotinamide increased in both groups. A MANOVA omnibus test performed after principal component analysis showed a significant difference in these 13 principal component (P = 0.014) between groups. Compared to HCs, nicotinamide levels were higher and indole-3-lactic acid levels lower in the IBS group. Melatonin and indole-3-acetic acid levels were associated with several subjective/objective sleep measures; decreased stool consistency/frequency and abdominal pain were positively associated with melatonin and serotonin in the IBS group. The kynurenine and kynurenic acid were associated with ACTH (positively) and cortisol/ACTH (negatively). CONCLUSIONS: Nighttime Trp metabolites may provide clues to poor sleep and stress with IBS. Further study of the mechanism of metabolite action is warranted.
