Background: A rectal neuroendocrine tumor (rNET) is a malignant tumor originating from neuroendocrine cells. Currently, tumor size is the primary basis for assessing tumor risk.

Case Summary: This article reports the case of a 46-year-old male patient who underwent a colonoscopy that found a 3 mm rectal polypoid bulge.

Background: Autoimmune atrophic gastritis (AAG) is a type of chronic gastritis that mainly affects the gastric corpus. Due to the lack of standard diagnostic criteria and overlaps with the courses of -related atrophic gastritis, reports on the diagnostic strategy of AAG at an early stage are limited.

Case Summary: A 71-year-old woman with severe anemia was diagnosed with AAG.

BackgroundHuman milk is rich in osteopontin (OPN), which has immunomodulatory functions.MethodsIn a randomized controlled trial, standard formula (SF) and the same formula with 65 mg of OPN/L (F65) or 130 mg of OPN/L (F130), representing ~50 and 100% of the OPN concentration in human milk, were compared. We examined frequencies and composition of peripheral blood immune cells by four-color immunoflow cytometry of formula-fed infants at ages 1, 4, and 6 months, and compared them with a breastfed (BF) reference group.

Objectives: Breast milk contains a high concentration of osteopontin (OPN), a protein having multiple functions. In contrast, infant formula is low in OPN. A randomized clinical trial was performed to evaluate effects of adding a highly enriched bovine OPN fraction to formula, and infants whose mothers had already decided not to breast-feed were recruited.

Objectives: To evaluate international differences in the development of minimum dietary diversity (MDD) between 6 and 12 months of age.

Study Design: Breastfed infants (115, 100, and 109 in Shanghai, Cincinnati, and Mexico City, respectively) were enrolled near birth and dietary intake assessed weekly by 24-hour recall of food frequency. Diet diversity per month from age 6-12 months was assessed as at least 4 of 7 food groups provided on the previous day.

Although vitamin D (vD) deficiency is common in breastfed infants and their mothers during pregnancy and lactation, a standardized global comparison is lacking. We studied the prevalence and risk factors for vD deficiency using a standardized protocol in a cohort of breastfeeding mother-infant pairs, enrolled in the Global Exploration of Human Milk Study, designed to examine longitudinally the effect of environment, diet and culture. Mothers planned to provide breast milk for at least three months post-partum and were enrolled at four weeks postpartum in Shanghai, China (n=112), Cincinnati, Ohio (n=119), and Mexico City, Mexico (n=113).

Background: The prevalence of adolescents' obesity and overweight has dramatically elevated in China. Obese children were likely to insulin resistance and dyslipidemia, which are risk factors of cardiovascular diseases. However there was no cut-off point of anthropometric values to predict the risk factors in Chinese adolescents.

Infant feeding practices generally influence infant growth, but it is unclear how introduction of specific foods affects growth across global populations. We studied 3 urban populations in the Global Exploration of Human Milk study to determine the association between infant feeding and anthropometry at 1 y of age. Three hundred sixty-five breastfeeding mother-infant pairs (120 US, 120 China, and 125 Mexico) were recruited soon after the infant's birth.

Objective: To investigate the variation of human breast milk adiponectin (APN) concentration during lactation, analyze the relationship of APN concentrations in human breast milk with APN in infant serum, determine the association between maternal milk APN and infant body proportionality in the first year of life, and the period of greatest human milk exposure.

Method: Subjects included 73 mother-infant pairs from Shanghai International Peace Maternity & Child Health Hospital. Maternal milk was collected at 2, 4, 13, 26 weeks and infant serum was collected at 26 weeks.

Objective: To meet the need for instrument assessing the cognitive abilities of infants and young children as well as discriminating between global developmental delay and particular deficits in either language or problem-solving skills, we intended to introduce Cognitive Adaptive Test/Clinical Linguistic and Auditory Milestone Scale (CAT/CLAMS) into China.

Methods: CAT/CLAMS were administered to 1604 normative children aged 4-36 months (in 16 age groups, about 100 children per age group) in Shanghai during the period from December 2003 to June 2004. In the meantime, Gesell Developmental Diagnosis was applied for 100 of these children, respectively aged 4, 6, 12, 18 and 30 months (20 children per age group).
