RESUMEN
BackgroundNarrative exposure therapy （NET）， an integration of narrative therapy and exposure therapy， has been shown to be effective in relieving the symptoms of post-traumatic stress disorder （PTSD）， which can help patients gain a deeper understanding of their trauma and is also considered to be quite safe. PTSD is highly prevalent in children and adolescents， while the effectiveness of NET intervention varies among the subjects. ObjectiveTo systematically evaluate the effectiveness of NET for PTSD in children and adolescents， so as to provide references for the clinical application of NET. MethodsOn August 1， 2022， the Cochrane Library， PubMed， Web of Science， CINAHL， China National Knowledge Infrastructure （CNKI）， SinoMed， VIP and Wanfang database were searched from their inception to June 2022. Search was conducted with the use of a combination of medical subject heading and free text terms， and randomized controlled trials relevant to NET for PTSD in children and adolescents were collected. Then the quality of the controlled trials was evaluated according to the Cochrane Collaboration's tool for assessing risk of bias （2011）， and Meta-analysis was performed using RevMan 5.4 software. ResultsNine randomized controlled trials involving 394 children and adolescents with PTSD were included. Meta-analysis showed that NET and relaxation therapy reported comparable symptom relief in PTSD patients within 1 to 3 months after intervention （SMD=0.22， 95% CI： -0.84~1.28） and at 6 months after intervention （SMD=0.21， 95% CI： -0.75~1.17）， while NET provided greater PTSD symptom relief than routine therapy both within 1 to 3 months after intervention （SMD=-0.66， 95% CI： -1.04~-0.27） and at 6 months after intervention （SMD=-0.77， 95% CI： -1.36~-0.19）， with statistically significant differences. Regarding the alleviation of depressive symptoms， the effect was similar between NET and routine therapy within 1 to 3 months after intervention （SMD=-0.39， 95% CI： -0.98~0.21） and at 6 months after intervention （SMD=-0.74， 95% CI： -2.23~0.75）. No statistical difference was demonstrated between NET and routine therapy in relieving psychological distress （SMD=-0.54， 95% CI： -2.14~1.07） and suppressing hyperorexia （SMD=-0.17， 95% CI： -0.54~0.19） 1 to 3 months after intervention. ConclusionNET yields a better outcome and a medium- and long-term effectiveness in alleviating symptoms of PTSD in children and adolescents compared with routine therapy， while it does not offer any significant advantages in improving depression symptoms， psychological distress and hyperorexia.
RESUMEN
Lactic acid bacteria (LAB) are a representative probiotic. As the dominant flora in the human intestinal tract, LAB can regulate the balance of human intestinal flora and improve host health. The purpose of this study was to isolate and screen LAB that are well suited to the intestinal characteristics of the Chinese population, with excellent probiotics and high antibacterial activity. After 16S ribosomal RNA (rRNA) homology and phylogenetic tree analysis, potential probiotics were tested for their antibacterial activity, resistance to artificial gastrointestinal fluid and drugs, surface hydrophobicity, and safety. Three strains of LAB with acid resistance, bile salt resistance, epithelial cell adhesion, and no multidrug resistance were selected:
RESUMEN
Objective To investigate the prevalence of nutritional risk and malnutrition,and the application of nutrition support in hospitalized patients with surgically treated gynecologic malignant tumors.Methods 237 hospitalized patients with malignant tumors receiving surgery in Department of Gynecology of Beijing Hospital from January 1 to December 31,2013 were continuously sampled.Nutritional Risk Screening 2002 (NRS 2002) was performed in the morning the day after admission.NRS 2002 score ≥ 3 was considered indicating nutritional risk.Malnutrition was judged in accordance with NRS 2002.The application of postoperative nutrition support was recorded.Results The nutritional risk screening was applicable in all the patients (100％).The prevalence of malnutrition was 5.1％ (12/237) in the whole study population,9.2％ in the elderly (≥65 years),significantly higher than that in the patients ＜ 65 years (2.7％) (P =0.034).The nutritional risk rate was 21.1％ (50/237),which was 29.9％ in the patients ≥ 65 years and significantly lower in the patients ＜ 65 years (16.0％) (P =0.014).The nutritional risk rate in the patients with ovarian and endometrial cancers was higher the rate in those patients with vaginal and vulvar cancer was lower.47 patients (19.8％)received postoperative nutrition support,all being parenteral nutrition,including total parenteral nutrition in 13 patients (5.5％) and single transfusion (providing two or more than two amongs glucose,fat emulsion,andi amino acids) in 34 (14.3％).Tube feeding was not applied in all the patients.33 cases (66％) in the 50 patients with nutritional risk were supported by parenteral nutrition,while 14 cases (7.5％) in the 187 patients without nutritional risk were supported by parenteral nutrition.Conclusions There is nutritional risk in the patients with gynecology malignant tumors,the rate of which is higher in elderly patents (≥ 65 years) than in the patients of other age groups.Therefore,attention must be paid to ensure adequate postoperative nutrition support in the elderly patients.
