Long-term civil conflict, migration, and the mental health of adults left behind in Thailand: a longitudinal study

Ford K, Jampaklay A, Chamratrithirong A

Int J Public Health, 2019 Nov;64(8):1193-1201.
PMID: 31489461 DOI: 10.1007/s00038-019-01297-y

OBJECTIVES: A long-term civil conflict has been occurring in the southernmost provinces of Thailand, and migration to Malaysia has been accelerated by this conflict. The objective of this work was to examine the influence of perceived effects of the unrest, migration of a household member, and children left behind on the reporting of psychiatric symptoms of working age adults.
METHODS: A first round of data collection was conducted in 2014 including interviews with a probability sample of 1102 households and individual interviews with 2058 males and females aged 18-59. In 2016, a second round of data collection was conducted. A fixed effects model was used in the analysis.
RESULTS: The perceived effect of the unrest on the household was associated with an increased reporting of psychiatric symptoms. Furthermore, the migration of a household member for work and the presence of children left behind were related to an increased reporting of psychiatric symptoms among adults, especially among females.
CONCLUSIONS: The unrest and its associated migration was related to an increased reporting of psychiatric symptoms among working age adults in the study population.
Psychiatric symptoms among migrants to Malaysia from the southernmost provinces of Thailand

AIM: The objective of this paper is to examine the level of psychiatric symptoms and associated factors among Thai migrants from the southernmost Thai provinces of Pattani, Yala, and Narithiwat who are working in Malaysia. Comparisons will be made with the sending population in the southernmost provinces of Thailand.
METHODS: Data are drawn from survey and in-depth interviews with Thai migrants who are working in Malaysia. Comparisons are made with a probability sample of working age adults in Thailand. The twenty item Self Reporting Questionnaire (SRQ) was the measure of mental health.
RESULTS: The study found that the migrants, on average, have normal levels of psychiatric symptoms. However, although about 24% of migrants reported more eight or more symptoms that may indicate a need for evaluation. There are many stressors in their lives including distance from families, reduced social support, legal matters surrounding immigration, and discrimination/exploitation of migrant groups.
CONCLUSION: The study highlights the need for policy makers and non-governmental organizations to give attention to migrants' mental health, well-being and sustainable livelihoods.
Migration and Unrest in the Deep South Thailand: A Multilevel Analysis of a Longitudinal Study

Although migration of Muslims from the southernmost provinces of Thailand to Malaysia has a long history, research suggests that the intensity of this migration has increased in the past 10 years along with increased unrest in the provinces. This study examines how migration in the three southernmost provinces is affected by the ongoing unrest. Data are drawn from household probability surveys conducted in 2014 and 2016. An individual sample of 3,467 persons who were household residents at the 2014 survey was followed to see who remained in the household of origin or moved out two years later (2016 survey). Data on violent events from the Deep South Watch, an independent organization, were used to measure exposure to violence. Results from a multilevel analysis show that net of other characteristics at the individual, household, and village levels, individuals who live in a village in which a violent event occurred in the previous year are more likely to move out than those who live in a village with no violent event in the previous year. Findings suggest that in addition to the economic reasons that have long motivated migration from this area, violent events accelerate this migration.
Fulltext Induction of fibroblast senescence generates a non-fibrogenic myofibroblast phenotype that differentially impacts on cancer prognosis

Cancer-associated fibroblasts (CAF) remain a poorly characterized, heterogeneous cell population. Here we characterized two previously described tumor-promoting CAF sub-types, smooth muscle actin (SMA)-positive myofibroblasts and senescent fibroblasts, identifying a novel link between the two. Analysis of CAF cultured ex vivo, showed that senescent CAF are predominantly SMA-positive; this was confirmed by immunochemistry in head & neck (HNSCC) and esophageal (EAC) cancers. In vitro, we found that fibroblasts induced to senesce develop molecular, ultrastructural and contractile features typical of myofibroblasts and this is dependent on canonical TGF-β signaling. Similar to TGF-β1-generated myofibroblasts, these cells secrete soluble factors that promote tumor cell motility. However, RNA-sequencing revealed significant transcriptomic differences between the two SMA-positive CAF groups, particularly in genes associated with extracellular matrix (ECM) deposition and organization, which differentially promote tumor cell invasion. Notably, second harmonic generation imaging and bioinformatic analysis of SMA-positive human HNSCC and EAC showed that collagen fiber organization correlates with poor prognosis, indicating that heterogeneity within the SMA-positive CAF population differentially impacts on survival. These results show that non-fibrogenic, SMA-positive myofibroblasts can be directly generated through induction of fibroblast senescence and suggest that senescence and myofibroblast differentiation are closely linked processes.
