Background and objectives The antiproteinuric effect of a renin-angiotensin-aldosterone system blockade can be magnified by dietary salt restriction. This study sought to determine the effect of intensive low-salt diet education on BP and urine albumin excretion in nondiabetic patients with hypertension and albuminuria. Conclusions The 24-hour urinary albumin excretion was decreased more in patients in the intensive low-salt diet education group than patients in the conventional education group. Weekly intensive education on a lowsalt diet would be a suitable method for clinical practice.

Background The virtual conference format has become an essential tool for professional development of researchers around the world since the outbreak of the COVID-19 pandemic. This study aims to identify empirical evidence of the benefits and challenges of virtual conferences by investigating participants’ experiences with them. Methods The study participants were delegates to the 40th annual meeting of the Korean Society of Nephrology, which was held virtually in September, 2020. A questionnaire was developed and implemented among the conference attendees. The 44-item questionnaire included five sub-scales related to participant perceptions of the virtual conference, which were (a) convenience and accessibility, (b) planning and organization, (c) technology use, (d) social exchanges, and (e) overall satisfaction, their preferences of conference formats, and their views of future projections for a virtual conference. Results A total of 279 delegates completed and returned the questionnaires (18.8% response rate). Participants varied in gender, age, profession, work location, and prior experience with conferences. On a four-point Likert scale (1 = “strongly disagree” and 4 = “strongly agree”), participants showed positive perceptions of the virtual conference in general, where the total mean (M) was 3.03 and less positive perceptions on social exchanges (M = 2.72). Participant perceptions of the virtual conference differed across age groups, professions, and prior experience with conferences (p < .05). Approximately half of the participants (n = 139) preferred the virtual format, and 33% (n = 92) preferred the conventional format. Participant preferences for the virtual format were somewhat evenly distributed between asynchronous (32.9%) and synchronous (29.1%) modes. Participants predicted a virtual conference would continue to be a popular delivery format after the end of the COVID-19. Conclusions Although participants had positive perceptions of the virtual conference, more support needs to be offered to those who may be less comfortable with using technology or with online interactions, and there is a need for improvement in supporting social exchange among attendees. Also, it is suggested that a blend of asynchronous and synchronous delivery methods should be considered to meet the varied needs of attendees.

Both systemic lupus erythematosus and Sjogren’s syndrome are autoimmune diseases. Almost all organs can be involved but the gall bladder is an unusual site. We report a 39-year-old woman with systemic lupus erythematosus and Sjogren’s syndrome presenting with acute acalculous cholecystitis. It is a very rare complication and, in the literature review, surgical interventions are mostly applied for treatment. In our case, high dose corticosteroid was tried and clinical manifestations and radiologic findings were improved.

Background: Positive attitudes for end-of-life (EOL) care along with adequate education are key factors for the provision of quality EOL care. This national study was conducted to identify the factors that influence attitudes toward EOL care on medical students. Method: An anonymous survey was designed and administered to fourth-year medical students at all 41 medical schools in Korea. Topics related to EOL care were assessed in classroom teaching, bedside teaching, and feedback experiences during clinical clerkships. Seven questions for self-rated attitudes and affecting factors were analyzed toward EOL care. Results: With a response rate of 49.2%, the median number of topics recognized by the students as having been delivered was 5 of 11 topics in classroom lectures and 1 of 8 topics in clinical experience. Although few (21.2%) participants indicated that they felt ready for EOL care practice, nevertheless, most felt that they should have adequate knowledge of and preparation for clinical competency in EOL care. Several parameters including respondent's demographics and exposure to EOL care topics in classroom and in bedside teaching influenced the responses to all 7 attitude questions. However, having more than 1 bedside experience was the only factor positively affecting all attitudinal measures. Conclusions: Clinical experience related to EOL care seems to be the utmost priory in fostering positive attitudes and competency among medical students.
