Diagnostic performance of individual characteristics and anthropometric measurements in detecting elevated serum alanine aminotransferase among children and adolescents.

BACKGROUND: Screening for elevated serum alanine aminotransferase (ALAT) can help identifying individuals at the risks of chronic and metabolic diseases, but blood collection is invasive and cannot be widely used for investigations. Considered as simple and inexpensive screening indices, individual characteristics and anthropometric measurements can be measured in a large crowd and may be important surrogate markers for ALAT levels. This study aimed to examine the diagnostic performance of individual characteristics and anthropometric parameters as predictive factors for discerning an elevated ALAT activity among Shenzhen children and adolescents. METHODS: A school-based screening study was performed from 9 high schools in Shenzhen during February 2017 and June 2018. Receiver operating characteristic curve was used to examine the diagnostic performance of each variable for detecting elevated ALAT. RESULTS: Altogether 7271 students aged 9-17 years were involved. The proportion of elevated ALAT greatly increased with increasing classification of BMI-z. By the sex-specific cut-offs for elevated ALAT (30 U/L boys; 19 U/L girls), BMI showed the highest area under the curve of 0.789 (95% CI 0.765-0.812) and followed by weight (0.779 [0.755-0.802]), BMI-z (0.747 [0.722-0.772]), height (0.622 [0.597-0.647]), and age (0.608 [0.584-0.632]), while height-z was not capable. With the cut-off of 67.8 kg for weight and 22.6 kg/m2 for BMI, the accuracy to identify elevated ALAT was 87.1% for weight and 82.9% for BMI. CONCLUSIONS: The presence of elevated ALAT was more common in overweight or obese children and adolescents. BMI and weight had the superiority of detecting elevated ALAT, followed by BMI-z, height, and age.

The prevalence and correlates of symptom distress and quality of life in Chinese oesophageal cancer patients undergoing chemotherapy after radical oesophagectomy.

PURPOSE: The current study was designed to describe the symptom distress and quality of life (QoL) in Chinese oesophageal cancer patients undergoing chemotherapy after radical oesophagectomy and to identify the factors that influenced symptom distress and the relationship between symptom distress and QoL. METHODS: The sample consisted of 102 oesophageal cancer patients undergoing chemotherapy after radical oesophagectomy. The patients completed the Chinese versions of the M.D. Anderson Symptom Inventory (MDASI, an instrument that measures symptom distress), the Hospital Anxiety and Depression Scale (HADS), the Medical Coping Modes Questionnaire (MCMQ) and the Functional Assessment of Cancer Treatment-General (FACT-G, an instrument that measures QoL). RESULTS: The symptoms and symptom interference scores of the patients in the current research were 3.62 (SD 1.66) and 2.94 (SD 1.76), respectively. Occupation after illness, anxiety, types of surgery, whether chemotherapy was on schedule and confrontation coping strategies were factors that influenced symptom distress. There was a negative relationship between symptom distress and QoL scores. CONCLUSION: Oesophageal cancer patients receiving chemotherapy suffer many limitations due to symptom distress and disruptions in their QoL. Oesophageal cancer patients should be assessed regularly and should be supported on an ongoing basis.
