Patients are prone to infection during the transplantation immune deficiency period. There has been a lot of clinical research into how to better manage this period of vulnerability. Objective: This study aims to investigate the efficacy of 2% chlorhexidine gluconate (CHG) for skin disinfection in patients undergoing autologous hematopoietic stem cell transplantation (HSCT) and observe any adverse reactions. Methods: A total of 106 patients receiving autologous hematopoietic stem cell transplantation from November 2019 to December 2020 in our district were selected as the control group. From January 2021 to January 2022, 106 patients with autologous hematopoietic stem cells were included in the experimental group. The control group used the immersion bath method. The experimental group was treated with an improved scrub bath method (including 3M 2% chlorhexidine gluconate medical sanitary wipes to wipe the whole skin once). Results: The bacteria-carrying rate of the improved method (37.74%) was significantly better than that of the traditional soaking method (72.64%), and the difference was statistically significant (P Conclusion: The improved bath/wipe method has a significant positive effect on skin disinfection for patients undergoing HSCT.展开更多

Taking all “conscious patients hospitalized for more than 48 hours” in the hospital on November 25, 2020 as the survey subjects, the patients’ appetite, dietary intake, nutrition and nutritional support in the past week were investigated. <strong>Results: </strong>A total of 890 cases were investigated, among which 25 cases (2.81%) with missing data were excluded, and thus 865 investigated cases were considered effective. The incidence of nutritional risk was 28.67%, malnutrition 13.29%, external tube feeding nutrition 3.24%, parenteral nutrition 7.05%, and oral nutritional supplement 10.40%. The average score of appetite assessment was (6.99 ± 2.43) points. Among them, cases with appetite assessment scores < 5 points accounted for 15.84%, and 52 patient cases utilized appetite-improving drugs. Among the 137 patients with appetite scores < 5, only 7 patients utilized appetite-improving drugs. The patients’ dietary self-evaluation scores were averagely (4.08 ± 1.16) points, and the daily intake compliance rate of patients was 85.78%. Appetite assessment score was correlated with dietary intake score (<em>r</em> = 0.548) and daily intake compliance rate (<em>r</em> = 0.263) (<em>p</em> < 0.01). The differences in body weight, BMI, grip strength, albumin, and hemoglobin concentration of patients with different appetite states were statistically different (<em>p</em> < 0.01). Appetite was an influencing factor of weight change (<em>β</em> = <span style="white-space:nowrap;">−</span>0.079, <em>p</em> = 0.023). The difference between the appetite assessment scores and the daily intake compliance rates of patients with different nutritional support methods was statistically significant (<em>p</em> < 0.05);the individualized diet group had the highest appetite assessment score (8.57 ± 1.70), while the parenteral nutrition group had the lowest appetite assessment score (4.90 ± 2.99);the individualized diet group had the highest daily intake rate of 100%, followed by the parenteral nutrition group with 96.72%, and the regular diet group had the lowest rate of 84.02%. <strong>Conclusion: </strong>The appetite of hospitalized patients is closely related to nutritional status, and therefore, attention should be paid to the appetite status and nutritional status of hospitalized patients. Inpatients with different nutritional support methods should be given individualized appetite and nutritional interventions.展开更多

We only included randomized controlled trials(RCTs) comparing the effect of surgical intervention with medical therapy for GERD. Statistical analyses were performed using Rev Man 5.2 and STATA 12.0 software. Rev Man 5.2 was used to assess the risk of bias and calculate the pooled effect size, while Stata 12.0 was used to evaluate publication bias and for sensitivity analysis. We evaluated the primary outcomes with GERD-/health-related quality of life in short(one to three years) and long(three to twelve years) periods of follow-up. Secondary outcomes evaluated were De Meester scores and the percentage of time that p H < 4 to evaluate the degree of acid exposure.RESULTS: This meta-analysis included 7 studies with 1972 patients. It showed a positive effect of antireflux surgery compared with medical treatment in terms of health-related quality of life [standardized mean difference(SMD) = 0.18; 95%CI: 0.01 to 0.34] and GERD-related quality of life(SMD = 0.35; 95%CI: 0.11 to 0.59). We also conducted the subgroup analyses based on follow-up periods and found that surgery remained more effective than medicine over the short to medium follow-up time, but the advantage of antireflux surgery probably not maintained for long time. GERD-related quality of life in the surgical group was significantly higher than medical group for the < 3 years follow-up(SMD = 0.45; 95%CI: 0.23 to 0.66); the difference was not statistically significant when the follow-up time was ≥ 3 years(SMD = 0.30; 95%CI:-0.10 to 0.69). Meta-analysis showed a statistically significant difference between thesurgical group and medical group in the percentage of time that p H < 4(SMD = 0.38; 95%CI: 0.14 to 0.61). Meta-analysis indicated a positive effect of antireflux surgery compared with medical treatment concerning De Meester scores(SMD = 0.32; 95%CI: 0.00 to 0.65).CONCLUSION: Although both were effective, in some respects surgical intervention was more effective than medical therapy to treat GERD when follow-up time was up to three years.展开更多
