1.Confounding factors in using upward feedback to assess the quality of medical training: a systematic review.
Journal of Educational Evaluation for Health Professions 2014;11(1):17-
PURPOSE: Upward feedback is becoming more widely used in medical training as a means of quality control. Multiple biases exist, thus the accuracy of upward feedback is debatable. This study aims to identify factors that could influence upward feedback, especially in medical training. METHODS: A systematic review using a structured search strategy was performed. Thirty-five databases were searched. Results were reviewed and relevant abstracts were shortlisted. All studies in English, both medical and non-medical literature, were included. A simple pro-forma was used initially to identify the pertinent areas of upward feedback, so that a focused pro-forma could be designed for data extraction. RESULTS: A total of 204 articles were reviewed. Most studies on upward feedback bias were evaluative studies and only covered Kirkpatrick level 1-reaction. Most studies evaluated trainers or training, were used for formative purposes and presented quantitative data. Accountability and confidentiality were the most common overt biases, whereas method of feedback was the most commonly implied bias within articles. CONCLUSION: Although different types of bias do exist, upward feedback does have a role in evaluating medical training. Accountability and confidentiality were the most common biases. Further research is required to evaluate which types of bias are associated with specific survey characteristics and which are potentially modifiable.

Objective To study the relationship between serum neuron-specific enolase(NSE)and clinical features of pheochromocytoma/paraganglioma(PPGL).Methods Totally 501 PPGL patients diagnosed from January 2019 to December 2022 were divided into normal NSE group(NSE≤16.3 ng/mL)and elevated NSE group(NSE>16.3 ng/mL).The clinical characteristics were compared between the two groups.Results Compared with normal NSE group,patients in the elevated NSE group had larger diameter in primary tumor(5.00 cm vs.4.60 cm),higher 24-hour urinary norepinephrine(NE)and 24-hour urinary dopamine(DA)levels,and a higher rate of metasta-sis(31.6%vs.13.7%)(P<0.05).NSE level was positively correlated with the primary tumor size(r=0.131,P<0.05),24-hour urinary NE level(r=0.195,P<0.05)and 24-hour urinary DA level(r=0.119,P<0.05).Conclusions The level of NSE is related to tumor size,secretion function and metastasis in PPGL patients.

Familial hyperaldosteronism type Ⅲ(FH-Ⅲ) is extremely rare, and there are no reported cases in China. Herein, we reported two cases with FH Ⅲ, both of which presented with severe hypertension and hypokalemia in their early childhood. One patient had significantly enlarged adrenal glands and developed clinical manifestations of Cushing′s syndrome at the age of 20. Complete relief of symptoms was achieved after bilateral adrenalectomy. The other case had normal adrenal imaging, and with spironolactone treatment, blood pressure and potassium levels were well-controlled. Both cases had germline mutation of KCNJ5 gene which were c. 433G>C(p.Glu145Gln) and c. 452G>A(p.Gly151Glu), respectively.

Objective To evaluate 99mTc-HYNIC-TOC somatostatin receptor and 131 I-MIBG imaging in clinical diag-nostic of pheochromocytoma and paraganglioma(PPGL).Methods This was a retrospective study.359 PPGL pa-tients diagnosed by pathology microscopy were included.The diagnostic sensitivity and influencing factors on 99mTc-HYNIC-TOC somatostatin receptor and 131 I-MIBG imaging were analyzed.Results The positive rate of 99mTc-HYN-IC-TOC somatostatin receptor scintigraphy was 57.7%(184/319)and 131I-MIBG imaging was 83.2%(232/279).The positive rates of 99m Tc-HYNIC-TOC somatostatin receptor imaging in the adrenal glands,retroperitoneum,head and neck,heart and mediastinum,pelvis and bladder were 53.3%,62.5%,95.0%,66.7%,50.0%and 11.0%respec-tively and the positive rates of 131I-MIBG imaging were 86.7%,88.5%,45.4%,50.0%,75.0%and 33.3%respec-tively.The positive rate of the two imaging did not showed difference among patients with different genetic back-grounds(SDH,VHL,RET mutations).The median maximum diameter of tumors was 4.4(3.0,6.1)cm.and the diag-nostic sensitivity of somatostatin receptor imaging and 131 I-MIBG imaging for larger tumors(≥4.4 cm)was signifi-cantly higher than those for the smaller tumor group(<4.4 cm)(64.0%vs.51.3%;92.3%vs.74.1%)(P<0.01).Tumors in 19 patients(5.3%)failed to uptake neither imaging method.Conclusions This is the largest PPGL cohort in China concerning 99m Tc-HYNIC-TOC somatostatin receptor imaging and 131 I-MIBG imaging.The sensitivity of 131 I-MIBG imaging is higher than that of 99m Tc-HYNIC-TOC somatostatin receptor imaging,but for some tumors,such as head and neck paraganglioma,the latter has obvious advantages.These two imagings technol-ogies are complementary and the choice of them should depend the individual situation of patients.
