Multidimensional anatomy of ‘modern type depression’ in Japan: A proposal for a different diagnostic approach to depression beyond the DSM‐5

Japan's prototype of depression was traditionally a melancholic depression based on the premorbid personality known as shūchaku‐kishitsu proposed by Mitsuzo Shimoda in the 1930s. However, since around 2000, a novel form of depression has emerged among Japanese youth. Called ‘modern type depression (MTD)’ by the mass media, the term has quickly gained popularity among the general public, though it has not been regarded as an official medical term. Likewise, lack of consensus guidelines for its diagnosis and treatment, and a dearth of scientific literature on MTD has led to confusion when dealing with it in clinical practice in Japan. In this review article, we summarize and discuss the present situation and issues regarding MTD by focusing on historical, diagnostic, psychosocial, and cultural perspectives. We also draw on international perspectives that begin to suggest that MTD is a phenomenon that may exist not only in Japan but also in many other countries with different sociocultural and historical backgrounds. It is therefore of interest to establish whether MTD is a culture‐specific phenomenon in Japan or a syndrome that can be classified using international diagnostic criteria as contained in the ICD or the DSM. We propose a novel diagnostic approach for depression that addresses MTD in order to combat the current confusion about depression under the present diagnostic systems.     

Prevention of Late-Onset Cytomegalovirus Infection and Disease in Donor-Positive/Recipient-Negative Kidney Transplant Recipients Using Low-Dose Valganciclovir

Background

The main challenge with cytomegalovirus (CMV) prophylaxis in IgG donor-positive/recipient-negative (D+/R–) kidney transplant recipients is late-onset CMV disease. We evaluated a novel protocol for the prevention of late-onset CMV infection and disease in D+/R? organ recipients.

Histamine stimulates alveolar macrophages to release neutrophil and monocyte chemotactic activity

Histamine and serotonin are important inflammatory mediators in the pathophysiology of asthma, and asthmatic patients have higher plasma histamine and serotonin levels than non-asthmatic control subjects. Alveolar macrophages (AMs) synthesize and secrete a large number of substances that play a key role in acute and chronic inflammation including asthma. We postulated that AMs might release chemotactic activity for neutrophils and monocytes in response to histamine or serotonin. To test this hypothesis, bovine AMs were cultured, and the supernatant fluids were evaluated for neutrophil chemotactic activity (NCA) and monocyte chemotactic activity (MCA) by a blind well chamber technique. AMs released chemotactic activity in response to histamine and serotonin in a dose- and time-dependent manner (P <.05). Partial characterization and molecular sieve column chromatography revealed that low-molecular-weight lipid-soluble activity was predominant. Lipoxygenase inhibitors significantly blocked the release of chemotactic activity. Leukotriene B(4) receptor antagonists blocked the chemotactic activity. Immunoreactive leukotriene B(4) significantly increased in supernatant fluids in response to histamine and serotonin. The receptor responsible for the release of chemotactic activity in response to histamine was the H2 receptor. These data demonstrate that AMs release NCA and MCA in response to histamine or serotonin (or both) and may modulate the inflammatory cell recruitment into the lung.     

Steroid Withdrawal Using Everolimus in ABO-Incompatible Kidney Transplant Recipients With Post-Transplant Diabetes Mellitus

Background

The effectiveness of everolimus (EVR) for ABO-incompatible (ABOi) kidney transplantation is unknown. We evaluated outcomes of conversion from steroid to EVR in ABOi kidney transplant recipients.

Effect of AA-2414 on early and late bronchial responses in actively sensitized guinea-pigs

The effect of a new thromboxane A2 receptor antagonist, AA-2414, (+/-)-7-(3,5,6-trimethyl-1,4-benzoquinon-2-yl)-7-phenylheptanoic acid, on dual bronchoconstriction and airway hyper-reactivity in actively sensitized guinea-pigs was investigated. Immediate and late bronchial responses were seen 1-10 min and 4-7 h, respectively, after inhalation of antigen. In guinea-pigs pretreated with AA-2414, 5 mg/kg orally, the immediate bronchial response was inhibited. An administration of AA-2414 inhibited the late bronchial response. The numbers of eosinophils, neutrophils and macrophages, but not of lymphocytes, in bronchoalveolar lavage fluid were increased at 4 h after antigen inhalation. AA-2414 did not affect the numbers of total cells, eosinophils, neutrophils or macrophages. Sensitized guinea-pigs showed a significant airway hyperreactivity to inhaled histamine, which was not influenced by an administration of AA-2414. Luminol-dependent chemiluminescence of airway-infiltrated cells from sensitized guinea-pigs stimulated with A23187 was slightly inhibited by AA-2414. These results show that AA-2414 inhibits the late asthmatic response and the production of oxygen radicals from airway-infiltrated cells.     

Pattern recognition as a caring partnership in families with cancer

Pattern recognition as a caring partnership in families with cancer The purpose of this study was to address the process of a caring partnership by elaborating pattern recognition as nursing intervention with families with cancer. It is based on Newman's theory of health as expanding consciousness within the unitary-transformative paradigm and is an extension of a previous study of Japanese women with ovarian cancer. A hermeneutic, dialectic method was used to engage 10 Japanese families in which the wife-mothers were hospitalized because of cancer diagnosis. The family included at least the woman with cancer and her primary caregiver. Each of four nurse-researchers entered into partnership with a different family and conducted three interviews with each family. The participants were asked to describe the meaningful persons and events in their family history. The family's story was transmuted into a diagram of sequential patterns of interactional configurations and shared with the family at the second meeting. Evidence of pattern recognition and insight into the meaning of the family pattern were identified further in the remaining meetings. The data revealed five dimensions of a transformative process. Most families found meaning in their patterns and made a shift from separated individuals within the family to trustful caring relationships. One-third of them went through this process within two interviews. The families showed increasing openness, connectedness and trustfulness in caring relationships. In partnership with the family, each nurse-researcher grasped the pattern of the family as a whole and experienced the meaning of caring. Pattern recognition as nursing intervention was a meaning-making transforming process in the family-nurse partnership.     

Bestatin administration and the change in cellular immunity

The change in cellular immunity by Bestatin (ubenimex) treatment--30 mg/day orally--was investigated in 23 gastrointestinal cancer patients for: 1), functional T cell subsets; 2), IL-2 receptor; 3), PHA-induced blastogenesis; and 4), PPD skin reaction. The absolute number of helper T cells (Th) and cytotoxic T cells (Tc) increased in 74 and 79% of cases, respectively, compared with pretreatment values. On the other hand, the absolute number of suppressor T cells (Ts) decreased in 79% of cases. IL-2 receptor increased in 56% of patients, PHA blastogenesis increased in 67% of patients and PPD skin reaction was elevated in 75% of cases comparing to pretreatment values. These results suggest that Bestatin could increase cellular immunity in cancer patients.
