Cytokines are important mediators of various stress-related modulations of immune function. A major genetic factor determining inter-individual differences in stress reactivity is polymorphisms of the serotonin (5-hydroxytryptamine, 5HT) transporter (5HTT) gene. A short (S) variant, compared with a long (L) variant, of the promoter region of the 5HTT gene-linked polymorphic region (5HTTLPR) has been related to emotional and stress hyper-reactivity. The present study examined whether the 5HTTLPR can modulate responses of inflammatory cytokines under acute stress. Nine Japanese male participants carrying two copies of the S alleles and nine Japanese males carrying S and L alleles underwent the Trier Social Stress Test (TSST). Inflammatory cytokines, endocrine parameters, heart rate and subjective stress were measured before, during and after the task. The participants carrying the SS alleles, but not those carrying the SL alleles, showed a significant increase of IL-1β immediately after TSST. This hyper-reactivity to acute stress in individuals with the SS alleles was also observed in their heart rate and cortisol levels. These results suggest that the S allele of the 5HTTLPR is consistently associated with stress reactivity in multi-level stress-related biological systems.

Myelodysplastic syndrome (MDS) is a heterogeneous clonal disorder characterized by insufficient hematopoiesis, peripheral blood cytopenia and an increased risk for malignant transformation to acute myeloid leukemia. Several factors, such as age, sex and lifestyle, promote the development of MDS syndrome. Oxidative stress, along with its detrimental effects, cause hematological disorders; however, its role in the pathogenesis of MDS is unknown.

Background/aims: Digestive disorders of gut-brain interaction (DGBI) are very common, predominant in females, and usually associated with intestinal barrier dysfunction, dysbiosis, and stress. We previously found that females have increased susceptibility to intestinal barrier dysfunction in response to acute stress. However, whether this is associated with changes in the small bowel microbiota remains unknown.

Purpose: Trauma disorders are prevalent and confer high rates of psychiatric comorbidity and functional impairment. Women are more likely to be affected by trauma disorders; however, rates and symptom burden in women's inpatient psychiatric units remains understudied. We hypothesized the prevalence of probable posttraumatic stress disorder (PTSD) would be higher among women admitted to a women's inpatient unit compared to women in the general population and mixed gender units.

Acute pancreatitis (AP) is a disease characterized by an acute inflammatory response in the pancreas. This is caused by the abnormal activation of pancreatic enzymes by a variety of etiologic factors, which results in a localized inflammatory response. The symptoms of this disease include abdominal pain, nausea and vomiting and fever.
