Effects of psychotherapy for middle-aged individuals with anxiety disorders in a general medicine practice

Background: Anxiety disorders are mental disorders that cause somatic symptoms for which patients may seek care from generalmedicine departments. We focused on anxiety disorders in middle-aged patients and examined the effect of a psychotherapeuticintervention.Materials and Methods: The participants were 14 middle-aged patients diagnosed with an anxiety disorder. Patients receivedpretreatment assessments and were randomly assigned to a pharmacotherapy group (n = 8) or a pharmacotherapy and psychotherapygroup (n = 6). The duration of the study was three months. Pre-and post-treatment, the Medical Outcomes Study 36-ItemShort-Form Health Survey (SF-36), State-Trait Anxiety Inventory (STAI), and a visual analog scale (VAS) were administered. Inthe pharmacotherapy and psychotherapy group, salivary cortisol was collected pre- and post-psychotherapy at the first and finalpsychotherapy sessions.Result: Four patients in the pharmacotherapy group withdrew from the study. There were no significant differences in the totalscores of the SF-36 or STAI between groups. Improvement was seen in the pharmacotherapy and psychotherapy group pre- andpost- treatment. SF-36 subscales of bodily pain (p = 0.02) and mental health (p = 0.04) were significantly higher than posttreatment.The state anxiety score on the STAI improved post-treatment (p = 0.03). On the VAS, the pharmacotherapy and psychotherapygroup’s symptoms were significantly improved (p = 0.02).Conclusion: This suggests that psychotherapy for middle-aged individuals contributes to the improvement of anxiety states andHRQoL in general medicine departments. It promotes the recognition of curative effects and prevents doctor shopping

Endoplasmic Reticulum Stress Contributes to Helicobacter Pylori VacA-Induced Apoptosis

Vacuolating cytotoxin A (VacA) is one of the important virulence factors produced by H. pylori. VacA induces apoptotic cell death, which is potentiated by ammonia. VacA also causes cell death by mitochondrial damage, via signaling pathways that are not fully defined. Our aim was to determine whether endoplasmic reticulum (ER) stress is associated with VacA-induced mitochondrial dysfunction and apoptosis. We found that C/EBP homologous protein (CHOP), a key signaling protein of ER stress-induced apoptosis, was transcriptionally up-regulated following incubation of gastric epithelial cells with VacA. The effect of VacA on CHOP induction was significantly enhanced by co-incubation with ammonium chloride. Phosphorylation of eukaryotic initiation factor 2 (eIF2)-alpha, which is known to occur downstream of the ER stress sensor PKR-like ERlocalized eIF2-alpha kinase (PERK) and to regulate CHOP expression, was also observed following incubation with VacA in the presence of ammonium chloride. Knockdown of CHOP by siRNA resulted in inhibition of VacA-induced apoptosis. Further studies showed that silencing of the PERK gene with siRNA attenuated VacA-mediated phosphorylation of eIF2-alpha, CHOP induction, expression of BH3-only protein Bim and Bax activation, and cell death induced by VacA with ammonium chloride, indicating that ER stress may lead to mitochondrial dysfunction during VacA-induced toxicity. Activation of ER stress and up-regulation of BH3-only proteins were also observed in human H. pylori-infected gastric mucosa. Collectively, this study reveals a possible association between VacA-induced apoptosis in gastric epithelial cells, and activation of ER stress in H. pylori-positive gastric mucosa

Detection of Epstein-Barr Virus and Helicobacter pylori in Primary Malignant Gastric Lymphomas

We studied five patients diagnosed with primary gastric lymphoma between 1985 and 1995 in Omura Munisipa Hospital to investigate the relationship between Helicobacter pylori, Epstein-Barr virus and primary malignant gastric lymphoma. H. pylori was detected by hematoxylin-eosin stain, Giemsa stain, immunohistochemistry while EBV was detected by in situ hybridization in the lymphoma and background mucosa. H. pylori but not EBV, was detected in all cases. Furthermore, malignant lymphomas were mainly located in the area of the fundic gland where H. pylori was frequently identified and caused inflammation. In contrast, malignant lymphomas were not detected in areas with intestinal metaplasia. Our results suggest that malignant lymphoma may develop in a region where the immune system has been activated by H. pylori. In contrast, EBV is unlikely to play an important role in the development of gastric lymphoma, compared to H. pylori

Dynamics of cancer cell subpopulations in primary and metastatic colorectal tumors

Intratumor heterogeneity—heterogeneity of cancer cells within a single tumor—is considered one of the most problematic factors of treatment. Genetic heterogeneity, such as in somatic mutations and chromosome aberrations, is a common characteristic of human solid tumors and is probably the basis of biological heterogeneity. Using mutations in APC, TP53 and KRAS as markers to identify distinct colorectal cancer subpopulations, we analyzed a total of 42 primary colorectal cancer tissues and six paired liver metastases with multipoint microsampling, which enabled analysis of mutation patterns and allelic imbalances with a resolution of 0.01 mm2 (about 200 cells). There was usually more than one subpopulation in each primary tumor. Only two of 15 (13.3%) cases with three gene mutations and eight of 27 (29.6%) cases with two gene mutations had a single subpopulation. Cells with mutations in all of the examined genes usually constituted the major population. Multipoint microsampling of six primary and metastatic tumor pairs revealed that the majority of discrepancies in mutation patterns found with the bulk tissue analysis were due to loss of subpopulations in the metastatic tissues. In addition, multipoint microsampling uncovered substantial changes in subpopulations that were not detected with bulk tissue analysis. Specifically, the proportion of KRAS mutation-negative subpopulations increased in the metastatic tumors of four cases. Because KRAS mutation status is linked to cetuximab/panitumumab efficacy, subpopulation dynamics could lead to differences in response to cetuximab/panitumumab in primary versus metastatic tumors

Current state of hypnotic use disorders: Results of a survey using the Japanese version of Benzodiazepine Dependence Self-Report Questionnaire

Aims Benzodiazepine receptor agonists (BZ-RAs) are frequently prescribed to treat insomnia; however, their long-term use is not recommended. To introduce an appropriate pharmaco-therapy, the current state and background factors of BZ-RAs\u27 dependence must be elucidated. In this study, we developed a Japanese version of the Benzodiazepine Dependence Self-Report Questionnaire (Bendep-SRQ-J) and conducted a study of BZ-RAs\u27 use disorder. Methods The Bendep-SRQ-J was created with permission from the original developer. Subjects were inpatients and outpatients receiving BZ-RAs between 2012 and 2013. Clinical data collected were Bendep-SRQ-J scores, sleep disorders for which BZ-RAs were prescribed, physical comorbidities, psychotropic drugs, and lifestyle factors. Logistic analysis was performed to extract factors associated with severe symptoms. Results Of the 707 patients prescribed BZ-RAs, 324 had voluntarily tapered or discontinued their drugs. Logistic analysis showed that the total number of drugs administered in the last 6 months correlated with both worsening of symptoms or conditions. This was more notable among younger patients, and the proportion of patients with severe symptoms or conditions increased with the increasing number of drugs. Conclusion Using the Bendep-SRQ-J, we elucidated the current state of BZ-RA dependence. Nearly half of the patients were non-compliant. The proportion of patients with severe symptoms or disease conditions increased with the increase in the number of drugs administered. These findings highlight the need for clinicians to be aware of the likelihood of benzodiazepine dependence, especially in young patients and patients prescribed multiple hypnotics

Ultraflex Stent Placement for Palliation of Esophageal Cancer

Nine patients with malignant esophageal obstruction were treated with non-covered or covered Ultraflex stents. All patients achieved palliation, six of nine patients showed improvement of at least one dysphagia grade, and five patients could tolerate a normal or near-normal diet. Major (massive bleeding) and minor complications (ingrowth, overgrowth, stent migration, and bleeding) were encountered during follow-up in 2 and 4 patients, respectively. Ultraflex stents for esophageal cancer offer effective palliative treatment and quickly improve dysphagia. However, care should be exercised particularly of potentially serious life-threatening complications such as massive bleeding
