Objective To investigate effect of standardized nutritional assessment, intervention, and monitoring on nutritional status of patients with cystic fibrosis (CF).Methods We recruited 6 consecutive patients with CF diagnosed from June 2005 to June 2015 in Peking Union Medical College Hospital, all given nutritional assessment and intervention.The clinical data and nutritional status of the patients were analyzed.Four cases were followed up, and their compliance and effect of nutritional intervention on their nutritional status were evaluated.Results The mean age of diagnosis of the patients was (19 ± 6) years.All the patients had recurrent onset of pulmonary infection and hypoxemia with varying degrees.The nutritional status was impaired in all the cases to different extent, with body mass index (BMI) of 3 patients under 20 years of age being lower than the third percentile of the standard growth curve for adolescents of the same age and sex.Mild microcytic hypochromic anemia existed in 2 cases, hypoalbuminemia in 2 cases (serum albumin ＜ 35 g/L in absence of liver or renal dysfunction), and decreased prealbumin level in 4 patients.The serum concentrations of Na, Cl, K, and Ca were approximately normal in all the 6 cases.Vitamin D level was detected in only 2 cases, all revealing vitamin D deficiency.High energy and high protein diet was suggested to all the patients, plus prescription of oral nutritional supplements for 5 patients.Diagnostic pancreatic enzyme replacement therapy (PERT) was performed in 3 patients who were suspected with exocrine pancreatic insufficiency (PI), together with fatsoluble vitamins supplementation including vitamin D3.Four CF patients were followed up for 11 to 39 months, of whom 1 was lost to follow-up after 11 months.During the follow-up period, 3 patients had progressive weight loss or growth retardation, and the other one patient failed to increase body weight.Dietary review of the 3 patients with available follow-up data revealed that actual energy intake and protein intake were only 46.1％-65.9％ and 44.1％-63.2％ of recommendation levels, respectively.By enhancing dietary education and guidance in follow-up, nutritional status of the patients was improved.Conclusion Intensive nutrition management, standardized nutritional intervention and monitoring, dietary guidance or enteral nutrition adjustment may constitute critical measures for improving nutritional status of CF patients.

Celiac disease (CD) is a chronic autoimmune gastrointestinal disorder induced by ingestion of gluten-containing foods.In the past CD was thought prevalent only in Western countries,whereas it has been found common throughout the world and increasing numbers of Chinese patients has been reported recently.However,there are still many deficiencies in management of patients with CD in China and either the diagnosis or the treatment of CD is lacking evidence-based clinical pathway.We report a case of a young woman with CD presenting with chronic diarrhea,abdominal distention,and weight loss,whose outcome was improved by following evidence-based guidelines of medical nutrition therapy.Diagnosis and treatment of the patient was analyzed with review of foreign and domestic literature to provide readers reference of the standardized nutritional intervention of CD.

OBJECTIVEThis study aims to determine the awareness oral medical interns about occupation safety protection of knowledge and to present a scientific basis for perfecting the occupation safety education system and standard protection behavior.

METHODSA self-designed questionnaire that used a retrospective questionnaire survey on 425 stomatological interns, scoring, and statistical analysis of the survey were performed. The questionnaire included occupation safety prevention knowledge, behavior cognitive, and protective behavior, among others.

RESULTSThe questionnaire recovery rate was 100%, and the average scores of the prevention knowledge and behavior cognitive were 4.55 ± 0.91 and 4.40 ± 1.05, respectively. More than 90% interns can conduct the conventional protection, and less than 40% can perform special protection. For the item "occupation safety protection knowledge", the scores of three grade III hospitals were higher than that of stomatological hospitals and second level of first-class hospitals; the difference was statistically significant (P < 0.001). For the items "behavior cognition" and "protective behavior", the scores of the second level of first-class hospitals were lower than those of grade III hospitals and stomatolgical hospitals (P < 0.001). The second level of first-class hospitals was relatively poor in safety protection knowledge, behavioral cognitive, and protection behavior. The average score was higher for than for boys in the three contents, and the average score of interns accepting pre-job training was higher than those rejected; the difference was statistically significant (P < 0.001).

CONCLUSIONThe occupation safety knowledge of oral medical interns is not sufficient, and the protective behavior is poor. Schools and hospitals should strengthen the intern occupation safety and protection education and improve the status of occupation safety behavior.
