China has seen the largest human migration in history, and the country's rapid urbanisation has important consequences for public health. A provincial analysis of its urbanisation trends shows shifting and accelerating rural-to-urban migration across the country and accompanying rapid increases in city size and population. The growing disease burden in urban areas attributable to nutrition and ...

Metastasis is one of the clinical parameters that has a strong negative influence on the prognosis of cancer patients. In recent years, significant advances have furthered our understanding of this process at the molecular and biological levels. This paper will discuss recent discoveries relating to the earliest, intra-tumoral stages of metastasis in cancer cells, specifically focusing on: (i) ...

This monograph provides a systematic analysis of interprovincial migration in China and regional population dynamics since the 1950s. Data were obtained from the 1% sample survey of 1987. Chapters are devoted to an examination of the main features of population distribution and spatial differences of major demographic indicators, the causes and selectivity of migration, and the structure of m...

This paper uses a unique panel dataset from China's initial reform of fiscal decentralization to analyze the relationships between fiscal decentralization, local economic development, and rural-rural undocumented inter-provincial labor mobility. Using a modified gravity model with Heckman Maximum Likelihood Estimation method, this paper shows that fiscal decentralization has two contending effe...

Epidural catheter (EC) migration is well documented entity in literature. However, most of these reports are consistent with introduction of Tuohy needle, either partially or completely, into intravascular, subdural and subarachnoid spaces prior to the placement of catheter. We report an intra-operative delayed migration of epidural catheter into subarachnoid space after apparently normal needl...

Mesh repair of the incisional hernia is a standard procedure and associated with lesser recurrence rate as compared to primary suture repair. Intraperitoneal mesh migration is a rare cause of recurrence after onlay mesh repair. Hereby, reporting a rare case of intra-peritoneal migration of polypropylene mesh and its adhesion to bowel wall following onlay mesh repair of incisional hernia.

The authors report a rare per-operative complication of intra-pelvic migration of dynamic hip screw, during osteosynthesis of an inter-trochanteric fracture. Possible reasons of migration are analyzed along with the importance of careful execution of the surgical technique to avoid such iatrogenic complications and medico-legal implications.
