BACKGROUND: Our previous observational cohort study, the Kashima Scan Study (KSS), identified associations between lifestyle, cerebral small vessel disease (SVD) as detected by magnetic resonance imaging of the brain, and disease outcomes including cognitive impairment and vascular diseases. However, established modifiers of the outcomes such as genetic background, drinking and exercise habits, and socioeconomic status were not considered. Regarding genetic factors in particular, the ALDH2 rs671 variant, East Asian-specific diversity, and APOE status are expected to have strong effects. The aim of KSS-2 is to examine the interactions of genetic background, lifestyle factors including drinking habit, socioeconomic status, and/or SVD markers for cognitive impairment, vascular disease, and death. METHOD: The KSS-2 is a prospective regional observational study of a healthy Japanese cohort that will clarify lifestyle habits to better maintain brain health from midlife by genotype. Japanese adults who underwent brain health checkups at their own expense are enrolled and will be followed-up for 10 years. We will extend the protocol of the KSS to include genetic background and potential confounding factors, including lifestyle (including drinking and exercise habit) and socioeconomic status, and perform survival analyses. The study outcomes are cognitive impairment, vascular events, and death. RESULTS: We enrolled 908 healthy adults (mean age 64.2 years; range 35 to 84 years; 41% male) from September 1, 2018 until December 31, 2024. CONCLUSION This study will provide important insights into the development of individualized health intervention strategies.

A 66-year-old, postmenopausal woman was referred to our hospital because of abnormal breast cancer screening results. A tumor was found in the upper outer part of the left breast. Biopsy revealed papillotubular carcinoma, ER (Allred score total score [TS] 3 = proportion score [PS] 2 + intensity score [IS] 1), PgR (Allred score TS 3 = PS 2 + IS 1), HER2 (2+), fluorescent in situ hybridization 1.1 (negative), and Ki-67 labeling index 15%. In diagnostic imaging, the tumor size was 35 mm. The diagnosis was T2N0M0 Stage IIA, luminal B-like breast cancer. First, letrozole 2.5 mg/day was administered as preoperative hormone therapy. After 2 months of treatment with letrozole, the tumor size had increased to 44 mm and preoperative hormone therapy was discontinued. She was started on preoperative chemotherapy (4 courses of epirubicin plus cyclophsphamide followed by 4 courses of triweekly docetaxel). The tumor size decreased, becoming undetectable. After these preoperative treatments, nipple-sparing mastectomy, sentinel lymph node biopsy, and breast reconstruction with a primary latissimus dorsi flap were performed. As of 3 years and 6 months after the operation, there has been no recurrence. At first, preoperative hormone therapy is performed for Luminal B-like breast cancer as in this case, if the response is insufficient, preoperative chemotherapy after hormone therapy may be a therapeutic option.

Primary mesenteric neuroendocrine tumor is extremely rare. Here we describe 2 cases of this disease. Case 1 was a 66-year-old man with a working diagnosis of gastrointestinal stromal tumor or mesenteric tumor who underwent laparoscopic tumor resection. Immunohistochemically, the final diagnosis was primary mesenteric neuroendocrine tumor G1. There has been no recurrence as of 25 months after surgery. Case 2 was an 80-year-old man with a working diagnosis of gastrointestinal stromal tumor or mesenteric tumor who also underwent laparoscopic tumor resection. Immunohistochemically, the final diagnosis was primary mesenteric neuroendocrine tumor G1. This is recurrence-free as of 36 months after surgery. Several cases of primary mesenteric neuroendocrine tumor have been reported, but most have been treated with open surgery. To date, there has been only 1 case of primary mesenteric NET that was resected in a pure laparoscopic procedure. In all 3 cases (including our 2 cases), the largest tumor diameter was 4 cm. It appears that laparoscopic surgery can be used to treat primary mesenteric neuroendocrine tumor of small size (＜ 4 cm) with minimal invasion.

Here, we report 3 cases of conservatively treated ischemic colitis with hepatic portal venous gas. In Case 1, an 84-year-old man visited the emergency department because of fatigue, vomiting, and upper abdominal pain. In Case 2, a 72-year-old man was hospitalized for rehabilitation in another hospital following cervical spine trauma. He had diarrhea and mesogastric pain for 2 days and was transferred to our hospital. In Case 3, an 89-year-old woman visited the emergency department because of upper abdominal pain and vomiting. In all cases, we diagnosed the illness as ischemic colitis with hepatic portal venous gas based on computed tomography findings, and the vital signs of all patients were stable. They were treated conservatively. They were able to resume oral intake and were discharged or transferred to another hospital. Hepatic portal venous gas has been considered a poor prognostic sign of severe diseases such as intestinal necrosis. However, recently, reports of cases treated conservatively have been increasing. Conservative treatment may be selected for ischemic colitis associated with hepatic portal venous gas taking into account the patient’s general condition.

A 14-year-old girl (Case 1) with respiratory distress during exercise was referred to our department after a pancreatic mass was detected by computed tomography (CT). Contrastenhanced CT scan showed a low-density mass measuring 2.5 × 2 cm in the body of the pancreas. Low signal intensity was seen on T1-weighted magnetic resonance imaging (MRI) and high signal intensity on T2-weighted MRI. We suspected solid-pseudopapillary neoplasm (SPN) of the pancreas and performed laparoscopy-assisted spleen-preserving distal pancreatectomy. The postoperative course was uneventful, and she was discharged on postoperative day 13. A 15-yearold girl (Case 2) with abdominal pain and fever was referred to our department after an abdominal cystic mass was detected by ultrasound examination. Contrast-enhanced CT showed a 4-cm well-circumscribed mass. Higher signal intensity was seen on T2-weighted MRI. We suspected SPN of the pancreas and performed laparoscopic spleen-preserving distal pancreatectomy. The postoperative course was uneventful, and she was discharged on postoperative day 8. Laparoscopic or laparoscopy-assisted surgery should be considered for SPN of the pancreas.

The patient was a 52-year-old woman who had undergone laparoscopic colectomy with lymph node dissection and inferior mesenteric artery preservation for cancer of the descending colon. Functional end-to-end anastomosis was performed using a linear stapler. Colonoscopy at the 1-year follow-up revealed a type 2 tumor at the anastomotic site. She was diagnosed with anastomotic recurrence. We performed laparoscopic high anterior resection with inferior mesenteric artery dissection. Rectal resection preceded mobilization of the mesocolon because of severe adhesion around the anastomotic site. Laparoscopic surgery for anastomotic site recurrence is an option under the condition that the initial surgery was laparoscopic.

The purpose of this study was to compare the results of open surgery and laparoscopic surgery for acute appendicitis in adults. In 2013, we primarily selected open surgery for acute appendicitis, but in 2017 we opted to select mainly laparoscopic surgery. We compared between 92 patients who had undergone open surgery in 2013 and 88 patients who underwent laparoscopic surgery group in 2017. There was no difference in age, sex, body mass index, white blood cell count, C-reactive protein, or perforation rate on computed tomography between the two groups. The laparoscopic surgery group had significantly longer operation time but significantly lower blood loss and postoperative complication rate. In particular, laparoscopic surgery was advantageous in terms of hemostasis for moderate bleeding. The results suggest that laparoscopic surgery may be more useful in adult appendicitis than open surgery.

The purpose of this study was to clarify feasibility of a booklet for families of children dying with incurable cancer. Of 267 pediatric oncology specialists, 76 (28%) participated in this cross-sectional survey. Ninety-three percent of participants answered that they were “likely to use” the booklet, and 86% percent answered that they believed the booklet was “helpful” for families. Some participants described various advantages of its use as follows: “able to communicate something that is difficult to put into words,” “easy to understand for families,” “families can read whenever they choose to,” and “able to grasp the direction of dying.” In contrast, other participants described points of attention of use as follows: “optimal timing to bring out,” “acceptance of families,” “direction as interdisciplinary team,” “confidential relationship between families and interdisciplinary team,” “disinclination among health care providers,” and “information volume of the booklet.” Thus, our results validated feasibility of the booklet. In conclusion, pediatric oncology specialists should provide their support of utilizing the booklet for families and assessing each family condition and advantage/attention of using the booklet.

The objective of this study was to identify the roles of clinical psychologists in palliative care teams by conducting focus group interviews. The participants were 7 physicians and nurses of highly active palliative care teams. Results from the qualitative analysis of interview content revealed that the most important knowledges needed by psychologists in palliative care is fundamental and specialized psychological knowledges and skills. The second most important was general and psychiatric medical knowledges regarding cancer. Otherwise, psychologists were expected to understand the roles of other staff members and the medical system, and provide mental and emotional support to medical staff. Our results clarified that psychologists require a broad understanding of medical care for cancer, good communication skills for interacting with other staff members, and the ability to actively utilize their psychiatric specialty to provide psychological support to patients, families and medical workers.

A decline in the immunopotential of the host plays an essential role in the occurrence of infections with methicillin-resistant Staphylococcus aureus (MRSA) or other multi-drug resistant microorganisms. In the present study, mytomycin C (MMC)-treated mice with or without the infection of MRSA were used to examine the bacteriostatic action as well as the immunopotentiating action of the promising herbal medicine, Hochu-ekki-to (HET). Basic experimental data showed the drug to be effective in the treatment of MRSA infection. Eight to ten week old male C57BL mice were injected with MMC at a dosage of 5mg/kg/day to inhibit the bone marrow, thus creating a mouse model with reduced immunopotential. A powder extract of HET was administered orally at a dosage of 500mg/kg/day for seven consecutive days. For the infection of MRSA 1×10⁹ cell were injected intraperitoneally. Peritoneal macrophages were prepared by the adherence technique. Macrophage migration, phagocytic activity, and the bactericidal activity were examined by the Boyden chamber method, by the phagocytosis for fluorescent-activated latex beads, and by the nitroblue tetra zolium (NBT) reduction test, respectively.
After the administration of HET, the number of white blood cells in the MMC-treated mice recovered to 80% of the normal value. In addition, the phagocytic activity of macrophages increased to 50%, although that of the non-treated group was only 20%. The bactericidal activity also recovered to a level close to the normal value. The ratio of neutrophils in the HET administered MMC-treated group increased to 2.2% (normal mice, 2.6%) whereas that of the MMC-treated control group was 0.5%. Concerning the function of the immunological cells, IL-1beta and IFNgamma levels were recovered by treatment with HET, as observed by IL-1beta, IL-2 and IFNgamma monitoring. The bacterial count in the liver of the MRSA challenged mice, with or without HET administration peaked 6 hours after the challenge. The number of the group with HET administration was, however, much greater than that of the group without HET administration. The bacteria count in the blood showed an increase 12 and 24 hours after the challenge. Even 24 hours after the challenge, a significant number of bacterial cells existed in the blood of the group without HET administration, whereas only a small number of cells were detected 6 hours after the challenge. All of the control mice died 8 days after the MRSA challenge, whereas the survival rates were 60% for HET treatment, 40% for the vancomycin treatment, and 80% for the HET plus vancomycin treatment, respectively.
As we move towards a society with a high percentage of elderly people, the authors believe Chinese herbal medicine, which activates the immunopotential, will be very helpful in the treatment of opportunistic infections that are common among elderly patients.
