Background: The standard strategy in Japan for locally advanced rectal cancer is total mesorectal excision plus adjuvant chemotherapy. However, large tumors significantly restrict pelvic manipulation of the distal side of the tumor during surgery;therefore, from an oncological point of view, it is better to shrink the tumor as much as possible preoperatively to optimize the circumferential resection margin. In recent years, advances in systemic chemotherapy have significantly improved the tumor reduction effect, enabling such drug therapy prior to surgery for locally advanced rectal cancer. We herein retrospectively evaluated the clinical, short-term outcomes of patients treated by neoadjuvant chemotherapy (NAC) using capecitabin and oxaliplatin (CAPOX), focusing on overall safety as well as clinical and pathological staging responses to NAC.

Methods: We applied the preoperative chemotherapy protocol to T3-4, any N, M0 or M1a (with resectable metastases) (UICC 8^th) Ra/Rb rectal cancers. The chemotherapy regimen consisted of four cycles of CAPOX. After NAC, curative intent surgery with total mesorectal excision/tumor-specific mesorectal excision with/without metastasectomy was performed. Adverse effects (AEs) and compliance with NAC, surgical complications, clinical and pathological staging were evaluated. All patients undergoing the protocol between January 2017 and June 2021 at Fukushima Medical University were enrolled.

Results: Twenty cases were enrolled. No severe AEs were observed either preoperatively or perioperatively. Preoperative assessment of NAC showed no cases of progressive disease (PD). Radical resection was achieved in all cases. Histological therapeutic grading after NAC revealed one grade 3, four grade 2, three grade 1b, eleven grade 1a and one grade 0 among all cases.

Conclusion: This study suggests that NAC for locally advanced rectal cancer is likely to be acceptable because there were no severe AEs pre- or perioperatively, radical resection was achieved in all cases, and there were no cases of PD.

A 768 g female neonate, born at 25 weeks' gestation, developed sepsis due to methicillin-resistant Staphylococcus epidermidis on day 14. Severe thrombocytopenia was observed, and hemophagocytic macrophages were identified in her peripheral blood smear. Cytokine profiles at the time of onset suggested that an inflammatory cytokine storm had activated lymphocytes and macrophages, leading to platelet phagocytosis. After administration of vancomycin for 14 days and immunoglobulin therapy, she improved without any complications. Considering the results of cytokine profiles, early intervention for infection may have prevented progression to hemophagocytic lymphohistiocytosis and reduced the severity of clinical symptoms.

Background: Postoperative pneumonia is one of the major complications after esophagectomy. The aim of this study was to determine whether bacterial cultures before esophagectomy could predict occurrence of postoperative pneumonia and help treatment strategies for postoperative pneumonia.

Methods: Sixty-nine patients who underwent subtotal esophagectomy at Fukushima Medical University Hospital between January 2017 and May 2021 were included in this study. We collected sputum, oral, and/or nasopharyngeal swabs for bacterial culture preoperatively from all patients and from those who were suspected of postoperative pulmonary infections. We compared cultured pathogenic bacteria obtained preoperatively and postoperatively from patients who developed postoperative pneumonia, and investigated their association with incidence of postoperative pneumonia.

Results: Postoperative pneumonia occurred in 22 of 69 patients (31%), including 13 cases of severe pneumonia with a Clavien-Dindo classification of grade IIIa or higher. Multivariate analysis revealed that longer operative duration (for 30 minutes increase;odds ratio 1.27, 95% CI 1.01-1.51, p=0.039) and positivity for preoperative bacterial culture (odds ratio 5.03, 95% CI 1.31-19.2, p=0.018) were independent risk factors for severe postoperative pneumonia, but not for all incidences of postoperative pneumonia. Of note, in only 5 of the 22 patients with pneumonia, the same pathogenic species were detected preoperatively and after the onset of pneumonia.

Conclusions: Our results imply that preoperative bacterial culture may be useful to predict severe postoperative pneumonia. However, it may not be useful in determining pathogenic bacteria responsible for postoperative pneumonia.

Aiming to improve post-disaster care of medical staff, we conducted an early and ongoing assessment of post-disaster psychologic distress and quality of life (QOL) in one center of a disaster-response hospital. Twelve days after the Great East Japan Earthquake, as the Fukushima Daiichi Nuclear Power Plant crisis was unfolding, we began a survey to examine the physical and mental state of medical staff to assess their motivation toward work. Surveys were administered in March 2011 (Survey 1), March 2012 (Survey 2), March 2013 (Survey 3), March 2014 (Survey 4), and March 2015 (Survey 5). Participants completed the Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), EuroQol (EQ-5D), and MOS Short-Form 36-item Health Survey (SF-36). Although BDI scores significantly improved over time following Survey 1, participants in their 30s had significantly higher Survey 2 scores than those in their 40s/50s, and significantly higher Survey 3 scores than those in their 20s. STAI scores significantly improved over time following Survey 1. However, participants in their 30s had significantly higher Survey 3 scores than those in their 20s. EQ-5D scores did not significantly vary among survey time points or age groups. SF-36 physical functioning, role physical, social functioning, role emotional, and mental health subscale scores significantly improved over time. In conclusion, post-disaster longitudinal changes, including recovery period, differed among age groups. Thus, age should be taken into account in longitudinal evaluations of psychologic distress and QOL in medical staff after a disaster and, as more recent events suggest, during a pandemic.

A tubo-ovarian abscess is an infection that occurs as a sequela of pelvic inflammatory disease. There is no reported association between a tubo-ovarian abscess and cri du chat syndrome in the medical literature. Herein, we report the case of a 44-year-old woman with cri du chat syndrome who was subsequently diagnosed with a tubo-ovarian abscess. After emergent laparotomy, simple total hysterectomy, and bilateral adnexectomy, the patient was discharged 13 days postoperatively without complications.

Background: In order for general practice / family medicine clerkships to be improved in undergraduate medical education, it is necessary to clarify the impacts of general practice / family medicine clerkships. Using text mining to analyze the reflective writing of medical students may be useful for further understanding the impacts of clinical clerkships on medical students.

Methods: The study involved 125 fifth-year Fukushima Medical University School of Medicine students in the academic year 2018-2019. The settings were three clinics and the study period was 5 days. The clerkships included outpatient and home visits. Students' reflective writing on their clerkship experience was collected on the final day. Text mining was used to extract the most frequent words (nouns) from the reflective writing. A co-occurrence network map was created to illustrate the relationships between the most frequent words.

Results: 124 students participated in the study. The total number of sentences extracted was 321 and the total number of words was 10,627. The top five frequently-occurring words were patient, home-visit, medical practice, medical care, and family. From the co-occurrence network map, a co-occurrence relationship was recognized between home-visit and family.

Conclusion: Data suggest that medical students may learn the necessity of care for the family as well as the patient in a home-care setting.
