Background: To find a genetic component in gastric cardia adenocarcinomas (GCA).
Methods: Age at onset (AO) and rate of another synchronous primary upper gastrointestinal carcinoma (RASPUGIC) were compared among the three GCA groups with positive (N = 766), negative (N = 2167), and missing family history of upper gastrointestinal cancer (FHUGIC) (N = 198). These 3131 GCAs were diagnosed on 3128 primary GCA patients of a consecutive surgical cohort treated from 1973 through 1994 at the Department of Thoracic Surgery in the 4th Hospital of Hebei Medical University in a high-risk region in northern China.
Results: Overall, GCAs of positive FHUGIC showed a significantly younger AO and a significantly higher RASPUGIC than the negative group (54.68 ± 7.35 vs 55.94 ± 7.47 years old, Pt-test = 0.000; 3.1% vs 1.3%, χ2 = 11.02, P = 0.001). The difference in AO and RASPUGIC between the positive and the negative FHUGIC GCAs is significant or nearly significant in most subgroups; minimizing the possibility of a false association due to bias or confounding (e.g. significant stage-specific differences in AO between familial and sporadic GCAs observed in the subgroup of T2,3N0M0 (P = 0.000) and T2,3,4N1M0 (P = 0.03) exclude the possibility of ascertainment bias towards an earlier diagnosis in familial cases), and the association between FHUGIC and RASPUGIC is statistically significant for GCAs of younger AO (<55 yr old, RASPUGIC 3.8% vs 1.6% vs 1.1% for the positive, negative and missing FHUGIC GCAs respectively, χ2 = 6.50, P = 0.04), but not significant for the later onset GCAs (≥55 yr old, RASPUGIC 2.5%, 1.1%, 1.9% for the positive, negative and missing FHUGIC respectively, χ2 = 4.22, P = 0.12).
Conclusion: These findings suggest a genetic component in GCA in the Chinese high-risk region, and genetic predisposition may determine the age at onset and number of primary upper gastrointestinal cancer.

BACKGROUND Cleidocranial dysplasia (CCD) is a rare (1: 1 000 000) autosomal dominant congenital skeletal dysplasia characterized by widely patent calvarial sutures, clavicular hypoplasia, supernumerary teeth, and short stature. Only a minority of the cases are diagnosed early after birth. We present another case of proven CCD presenting with typical neonatal phenotype to promote awareness of this rare disorder.

Seed size is a trait which determines survival rates for individual plants and can vary as a result of numerous trade-offs. In the palm family (Arecaceae) today, there is great variation in seed sizes. Past studies attempting to establish drivers for palm seed evolution have sometimes yielded contradictory findings in part because modern seed size variations are complicated by long-term legacies, including biogeographic differences across lineages.

Background: Of the numerous complications encountered by people with diabetes (PWD), the effect on mental health is concerning. Within mental health, diabetes distress (DD) occurs when a patient has unfavourable emotional stress while managing their condition, which can be managed by coping strategies but are less studied together in Indian settings. So, the present study aimed to determine the proportion of DD and associated factors and coping skills among the PWD.

Background: Childhood Interpersonal Trauma (CIT) is a major public health issue that increases the risk of perpetrating and sustaining intimate partner violence (IPV) in adulthood, perpetuating intergenerational cycles of violence. Yet, the explanatory mechanisms behind the intergenerational transmission of trauma warrant further exploration.
Objective: This study explored identity diffusion as an explanatory mechanism linking cumulative and individual CIT (sexual, physical and psychological abuse, physical and psychological neglect, witnessing parental physical or psychological IPV, bullying) to IPV (sexual, physical, psychological, coercive control) and to the next generation's exposure to family violence.
