Effect of Laparoscopic Proximal Gastrectomy With Double-Tract Reconstruction vs Total Gastrectomy on Hemoglobin Level and Vitamin B12 Supplementation in Upper-Third Early Gastric Cancer: A Randomized Clinical Trial.

Importance: Patients undergoing proximal gastrectomy (PG) with double-tract reconstruction (DTR) have been reported to have an incidence of reflux esophagitis that is as low as that observed after total gastrectomy (TG). It is unclear whether PG has an advantage over TG for the treatment of patients with upper early gastric cancer (GC). Objective: To evaluate the effect of laparoscopic PG with DTR (LPG-DTR) vs laparoscopic TG (LTG) on levels of hemoglobin and vitamin B12 supplementation required among patients with clinically early GC in the upper third of the stomach (upper-third early GC). Design, Setting, and Participants: This multicenter open-label superiority randomized clinical trial was conducted at 10 institutions in Korea. A total of 138 patients with upper-third cT1N0M0 GC were enrolled between October 27, 2016, and September 9, 2018. Follow-up ended on December 3, 2020. Interventions: Patients were randomized to undergo either LPG-DTR or LTG. Main Outcomes and Measures: The primary co-end points were change in hemoglobin level and cumulative amount of vitamin B12 supplementation at 2 years after LPG-DTR or LTG. The secondary end points included morbidity, postoperative reflux esophagitis, quality of life, overall survival, and disease-free survival. Quality of life outcomes were assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) 30-item core questionnaire (C30) and the EORTC QLQ stomach cancer-specific questionnaire at 3 months, 12 months, and 24 months. Results: Among 138 patients (mean [SD] age, 60.0 [10.9] years; 87 men [63.0%]; all of Asian race and Korean ethnicity), 68 (mean [SD] age, 56.7 [10.4] years; 39 men [57.4%]) were randomized to receive LPG-DTR and 69 (mean [SD] age, 61.3 [11.3] years; 48 men [69.6%]) were randomized to receive LTG. The mean (SD) changes in hemoglobin levels from baseline to month 24 were -5.6% (7.4%) in the LPG-DTR group and -6.9% (8.3%) in the LTG group, for an estimated difference of -1.3% (95% CI, -4.0% to 1.4%; P = .35). The mean (SD) cumulative amount of vitamin B12 supplementation was 0.4 (1.3) mg in the LPG-DTR group and 2.5 (3.0) mg in the LTG group, for an estimated difference of 2.1 mg (95% CI, 1.3-2.9 mg; P < .001). The late complication rates in the LPG-DTR and LTG groups were 17.6% and 10.1%, respectively (P = .31). The incidence of reflux esophagitis was not different between the LPG-DTR and LTG groups (2.9% vs 2.9%; P = .99). Compared with the LTG group, the LPG-DTR group had better physical functioning scores (85.2 [15.6] vs 79.9 [19.3]; P = .03) and social functioning scores (89.5 [17.9] vs 82.4 [19.4]; P = .03) on the EORTC QLQ-C30. Two-year overall survival (98.5% vs 100%; P = .33) and disease-free survival (98.5% vs 97.1%; P = .54) did not significantly differ between the LPG-DTR vs LTG groups. Conclusions and Relevance: In this study, patients with upper-third early GC who received LPG-DTR required less vitamin B12 supplementation than those who received LTG, with no increase in complication rates and no difference in overall and disease-free survival rates. There was no difference in change in hemoglobin level between groups. In addition, the LPG-DTR group had better physical and social functioning than the LTG group. These findings suggest that LPG-DTR may be as safe as LTG and may be a function-preserving procedure for the treatment of patients with upper-third early GC.

The Effects of a Science-Based Community Intervention on Health Outcomes in Minority Children: The Translational Health in Nutrition and Kinesiology Program.

BACKGROUND: This study evaluated the effects of a novel nutrition and movement science after-school program integrating laboratory experiences for minority children. Laboratory experiences demonstrated how the body moves, functions, and performs in response to exercise and healthy nutrition. METHODS: A total of 76 children from 4 after-school programs that were primarily Latino and black were randomly assigned to either an experimental translational health in nutrition and kinesiology (THINK; n = 46) or standard curriculum that served as the control group (CON; n = 30). An analysis of covariance controlling for baseline values was used to compare differences between THINK and CON after the 4-month intervention. RESULTS: Following the program, THINK participants evidenced lower triceps and subscapular skinfold thickness (P < .01 and <.05, respectively). THINK students showed greater improvements in aerobic fitness, grip strength, and agility than CON (P < .01, <.01, and <.05, respectively). Participants in THINK also demonstrated higher scores on their nutrition habits/behaviors questionnaire (P < .01), nutrition science (P < .05), and exercise fitness tests (P < .001) than CON. CONCLUSION: An innovative curriculum featuring nutrition and kinesiology education interfaced with hands-on laboratory experiences and physical activities can improve physical outcomes and health-related behaviors in after-school programs serving minority children.

Effectiveness of different music interventions on managing symptoms in cancer survivors: A meta-analysis.

PURPOSE: Music-based interventions can provide non-pharmacological, low-cost treatment for symptoms. This meta-analysis's purpose is to examine music-based interventions' effectiveness on psychological distress symptoms (anxiety, stress, and depressive symptoms), aspects of positive psychology (benefit-finding and resilience), and quality of life (QoL). METHODS: This meta-analysis was conducted according to PRISMA guidelines and meta-analytic methods suggested by Hedges and Olkin (1985). A systematic literature search between 2000 and 2020 was conducted using CINAHL, MEDLINE, PsycINFO, PubMed, and Web of Science databases. Studies and intervention characteristics were independently coded. The Quality Assessment Tool for Quantitative Studies, Cochrane Collaboration's Tool for Assessing Risk of Bias, Begg and Mazumdar's rank correlation, and Egger's regression test evaluated publication bias. RESULTS: Twenty-nine of thirty-five eligible studies were included in the statistical analysis. The overall (g = 0.34, SE = 2.27, p < 0.05) and psychological distress symptoms sub-outcome type (g = 0.47, SE = 0.18, p < 0.05) models with moderator analyses were statistically significant. CONCLUSIONS: Culturally appropriate music-based interventions conducted in the clinical setting that used passive listening with headphones, occurring ≥ 3-times a week over ≥ 2 months, positively impacted gynecology survivors undergoing chemotherapy and surgical treatments. Specifically, interventions that were ≥ 35-minutes, listening to folk or mixed-music positively impacted psychological distress symptoms, whereas new-age music negatively impacted psychological distress symptoms, positive psychology, and QoL outcomes. Future research should examine positive psychology characteristics (perceived levels of positive adjustment, change, and coping) and include larger cohorts with various cancer populations across all cancer survivorship continuum. Culturally appropriate interventions could lead to greater adherence, compliance, and clinical effectiveness and increase the findings' significance and generalizability.

Prevention of benign paroxysmal positional vertigo with vitamin D supplementation: A randomized trial.

OBJECTIVE: To assess the effect of vitamin D and calcium supplementation in preventing recurrences of benign paroxysmal positional vertigo (BPPV). METHODS: We performed an investigator-initiated, blinded-outcome assessor, parallel, multicenter, randomized controlled trial in 8 hospitals between December 2013 and May 2017. Patients with confirmed BPPV were randomly assigned to the intervention (n = 518) or the observation (n = 532) group after successful treatment with canalith repositioning maneuvers. The primary outcome was the annual recurrence rate (ARR). Patients in the intervention group had taken vitamin D 400 IU and 500 mg of calcium carbonate twice a day for 1 year when serum vitamin D level was lower than 20 ng/mL. Patients in the observation group were assigned to follow-ups without further vitamin D evaluation or supplementation. RESULTS: The intervention group showed a reduction in the ARR (0.83 [95% confidence interval (CI), 0.74-0.92] vs 1.10 [95% CI, 1.00-1.19] recurrences per 1 person-year) with an incidence rate ratio of 0.76 (95% CI, 0.66-0.87, p < 0.001) and an absolute rate ratio of -0.27 (-0.40 to -0.14) from intention-to-treat analysis. The number needed to treat was 3.70 (95% CI, 2.50-7.14). The proportion of patients with recurrence was also lower in the intervention than in the observation group (37.8 vs 46.7%, p = 0.005). CONCLUSIONS: Supplementation of vitamin D and calcium may be considered in patients with frequent attacks of BPPV, especially when serum vitamin D is subnormal. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that for patients with BPPV, vitamin D and calcium supplementation reduces recurrences of BPPV.

The Effect of Coffee Consumption on the Prevalence of Diabetes Mellitus: The 2012-2016 Korea National Health and Nutrition Examination Survey.

An inverse association between coffee consumption and the risk of diabetes mellitus (DM) has been observed. However, little is known about this association in Koreans, although they are now among the top global consumers of coffee. Therefore, the aim of this study was to evaluate the association between the prevalence of DM and the amount of coffee consumption using a unit of exact measurement, regardless of the type of coffee consumed. This study was based on data acquired from the Korea National Health and Nutrition Examination Survey 2012-2016. The participants who completed the survey were included in the statistical analysis (n = 14,578). Subjects were stratified by age (19-39 years old: young adult; 40-64 years old: middle-aged adult) and gender (men, women). The amount of coffee was measured using a teaspoon (tsp) unit corresponding to 5 mL of powdered coffee and was analyzed as a continuous variable. The mean powdered coffee intake per day was 1.97 tsp in women groups, 2.24 tsp in young adult men, and 2.72 tsp in middle-aged men. The frequency of coffee consumption showed an inverse relationship with the amount of coffee intake at a time. With each 1-tsp increment in daily coffee intake, the odds of DM were 0.89 (95% confidence interval (CI): 0.86-0.92, p < 0.001) and 0.93 (95% CI: 0.90-0.95, p = 0.003) in middle-aged women and men, respectively. Coffee consumption was inversely correlated with the prevalence of DM even with adjustment for covariates in middle-aged adults. We delineated that the prevalence for DM decreased as coffee intake increased in Korean middle-aged adults. Therefore, our data represented an inverse association between coffee consumption and the prevalence of DM, although Koreans have a unique coffee-drinking habit.

Impact of Vancomycin MIC on Treatment Outcomes in Invasive Staphylococcus aureus Infections.

There are conflicting data on the association of vancomycin MIC (VAN-MIC) with treatment outcomes in Staphylococcus aureus infections. We investigated the relationship between high VAN-MIC and 30-day mortality and identified the risk factors for mortality in a large cohort of patients with invasive S. aureus (ISA) infections, defined as the isolation of S. aureus from a normally sterile site. Over a 2-year period, 1,027 adult patients with ISA infections were enrolled in 10 hospitals, including 673 (66%) patients with methicillin-resistant S. aureus (MRSA) infections. There were 200 (19.5%) isolates with high VAN-MIC (≥1.5 mg/liter) by Etest and 87 (8.5%) by broth microdilution (BMD). The all-cause 30-day mortality rate was 27.4%. High VAN-MIC by either method was not associated with all-cause 30-day mortality, and this finding was consistent across MIC methodologies and methicillin susceptibilities. We conclude that high VAN-MIC is not associated with increased risk of all-cause 30-day mortality in ISA infections. Our data support the view that VAN-MIC alone is not sufficient evidence to change current clinical practice.

A comparison of manual guidance and knowledge of results in the learning of a weight-bearing skill.

BACKGROUND AND PURPOSE: Patients with certain neurological or orthopedic conditions often present with asymmetrical weight-bearing in stance. In the treatment of such patients, physical therapists often use manual guidance to promote symmetrical weight-bearing. Research investigating the efficacy of manual guidance to effect a change in weight-bearing status however, is lacking. As a first step in assessing the utility of such guidance, the present study compared the effect of providing two frequencies of manual guidance and of knowledge of results (KR) in the learning of a weight-bearing skill in healthy subjects. SUBJECTS AND METHODS: Forty healthy subjects (20 males and 20 females) with a mean age of 21.8 years (SD = 4.9 years) were randomly assigned to one of four groups differentiated on the basis of the type and frequency of information provided for learning. Subjects were required to learn to distribute their weight on their feet at a 70:30 ratio. Following a pretest, one group of subjects was positioned by experimenter-provided manual guidance at the hips until 70% of their weight was on one foot, as determined by a bathroom scale. This guidance was provided on every trial for 10 blocks of 12 trials (GD100%). A second group was provided with guidance on every third trial (GD33%), with the other two trials being performed without any assistance. A third group was verbally provided with KR regarding the percentage of body weight on the test foot after every trial (KR100%) while the final group was given KR after every third trial (KR33%). Following acquisition, retention tests were performed 10 minutes, one day, and one week later during which no feedback or guidance was given. RESULTS: No difference between groups was found at the pretest, but an analysis of variance performed on the accuracy of achieving the 70% goal in retention revealed main effects for technique and frequency. These effects were overshadowed by a significant interaction of these variables with retention test. Analysis of this interaction revealed that the most accurate performance was exhibited by the KR33% group while the GD100% group consistently exhibited the poorest learning. The GD33% and KR100% groups showed a decrease in performance accuracy with time following practice. DISCUSSION AND CONCLUSION: These results indicate that infrequent KR was the most effective technique in learning to modify weight-bearing status and that frequent manual guidance during practice is ineffective for learning this task. The next step is to determine whether these findings hold in subjects with various orthopedic and neurological conditions.
