Little is known about early death after admission during the terminal phase in advanced cancer patients. We retrospectively analyzed data from 510 advanced cancer patients who were at the end-of-life between August 2011 and August 2016, and found that 83 patients (16.3%) died within 3 days after admission to our institute. We divided the deceased patients into those who died within 3 days (early death group) and those who died after more than 4 days (non-early death group) after admission. Prevalence of delirium, cancer pain, dyspnea, nausea and vomiting, and fatigue patients showed no significant differences. Mean hydration at the end of life was significantly more per infusion for early death group than non-early death group. Continuous sedation and mean opioid use was significantly less for early death group than non-early death group. The risk factor of age, sex, clinical stage, histological state, overtreatment of chemotherapy, comorbidity had no significant associated with early death. The primary site of cancer, the number of metastatic sites, the consciousness level, and the performance status might be predictors for early death after admission in advanced cancer patients at the end-of-life.

97 baseball players from high school, universities and companies were subjected to this study in order to attempt to clarify the relationship between derangement of the elbow joint and lateral instabilitly by measuring various conventional parameters and the degree of lateral instability.
From the survey by questionnaire, 29 out of 97 players complained of elbow pain, paticularily on the medial side of the joint. The painful phases of the throwing motions were the acceleration phase (23 players, 61%) and release phase (7 players, 46%) . The hyperexten sion of the elbow on the dominant side was significantly smaller than that observed on the undominant side. X-ray examination revealed osteophyte formation at the tip of olecranon and medial joint space.
On the application of 63 kg⋅cm torque force, the varus deflection angle for the dominant side was 8.3° and that for the undominant side was 8.8°. The valgus angle for the dominant side was 12.2° and that for the undominant side was 10.8°. The varus stiffness (kg⋅cm/angle) was 9.5 for the dominant side and 8.4 for the undominant side. Valgus stiffness were 6.3 for the dominant side and 9.2 for the undominant side.
Thses results indicate that the lateral side become stiffer and medial side become looser in the dominant elbow than in the undominant one.
The unphysiological valgus stress at the acceleration phase would induce the osteophyte formation as well as the elongation of the medial collateral ligament on the medial side of the elbow. At the same time the impigement of the olecranon at follow through phase, would induce the osteophyte formation around the olecranon. Thses two factors would considerably influence the range of motion and the instability of the elbow joint.

We have several choices against bleeding and obstruction in advanced gastric cancer patients such as surgical or endoscopic therapy. But we have few reports about palliative radiation. We conduct this study that we perform palliative radiation for unresectable advanced gastric cancer patients between April 2006 and March 2014 in single center. In the aim of the therapy, to stop gastric bleeding were 8, and to improve obstruction depend on gastric cancer were 4. Response rate of stop bleeding was 63%, and improve obstruction was 50%. Median duration of stop bleeding was 103 day, and improve obstruction was 52 day. Overall survival time was 567 day, survival time after the start of radiotherapy was 105days. Radiotherapy was limited in cases because onset time of response needed in comparison with surgical or endoscopic therapy. However, given minimally invasive therapy and a certain response, we can choice it so much more.

The Wnt signaling pathway is conserved in various species from worms to mammals, and plays important roles in cellular proliferation, differentiation, and migration. Wnt stabilizes cytoplasmic beta-catenin and then the accumulated beta-catenin is translocated into the nucleus, where it activates the transcriptional factor T-cell factor (Tcf)/lymphoid enhancer factor (Lef), and thereby stimulates the expression of genes including c-myc, c-jun, fra-1, and cyclin D1. Tight regulation of this response involves post-translational modifications of the components of the Wnt signaling pathway. Phosphorylation, ubiquitination, and sumoylation have been shown to affect the half-life of beta-catenin and the transcriptional activity of Tcf/Lef. The precise spatio-temporal patterns of these multiple modifications determine the driving force of various cellular responses.

In malaria endemic areas, people naturally acquire an age-related immunity to malaria. Part of this immunity involves anti-malarial specific antibodies. Acquisition of these malaria-specific antibodies depends not only on exposure to malaria parasites but also on the human genetic predisposition. CTLA-4 is a costimulatory molecule that delivers an inhibitory signal to suppress T-cell as well as B-cell responses. We investigated associations between malaria-specific antibody levels and CTLA-4 polymorphisms in 189 subjects living in a hyper-endemic area of Papua New Guinea (PNG), where both P. falciparum and P. vivax are prevalent. We determined P. falciparum⁄ P. vivax specific IgG⁄IgE levels (Pf-IgG, Pv-IgG, Pf-IgE, Pv-IgE) and polymorphisms in the CTLA-4 gene at position -1661 promoter region (A⁄G), the +49 exon 1 non-synonymous mutation (A⁄G), and the +6230 3‘-UTR (A⁄G). All quantified antibody levels were significantly higher in subjects > 5 years (n = 150) than in subjects ≤ 5 years of age (n = 39). In children ≤ 5 years old, significant associations were detected between CTLA-4 +49 (GG⁄AG vs. AA) and Pv-IgG (median 18.7 vs. 13.7 Μg⁄ml, P = 0.017) and Pv-IgE (266.6 vs. 146.5 pg⁄ml, P = 0.046). No significant difference was observed in subjects > 5 years old. These results suggest that the CTLA-4+49 polymorphism influenced Pv-IgG and Pv-IgE levels among children less than five years old in the studied population, which may regulate the age- and species-specific clinical outcomes of malaria infection.

Purpose:
Twenty five years have passed since the first national survey on erectile dysfunction (ED) in Japan. The Japanese Society for Sexual Medicine conducted a nationwide survey on the actual status of sexual function targeting men over 20 years old in Japan using validated questionnaires commonly used in clinical practice.
Materials and Methods:
Japanese men aged 20 to 79 years participated in our online epidemiological study on sexual dysfunction. Erectile status was assessed by direct questioning and specific questionnaires. Risk factors and frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were assessed. The prevalence of these risk factors was compared between men with and without ED. Prevalence and frequencies were calculated for each 5-year age group. Main outcomes were the prevalence and number of patients with ED and simultaneous evaluation of age-related variations.
Results:
Direct questioning of the men revealed that 13.0% felt troubled by ED. Although 81.0% of them had at least some ED symptoms based on a Sexual Health Inventory For Men score of ≤21, the prevalence of men with ED by Erection Hardness Score (EHS), the most appropriate questionnaire for Japanese with low sexual activity, was 30.9%, indicating that 14,012,596 men have ED. Most risk factors were related with ED, whereas frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were affected by aging. However, the low frequency of these factors in the young generation was surprising.
Conclusions
The EHS-based assessment revealed a prevalence of ED of 30.9%, which affected approximately 14 million men, and that the sexual desire, erection stiffness, orgasms, and satisfaction were lower than expected in young Japanese men, especially those aged 20 to 24 years, although those factors tended to worsen with aging. We believe that these findings actually reveal the current sexual status of men in Japan.
