Objective: Human papillomavirus (HPV) vaccination is crucial, particularly for preventing cervical cancer. This study aimed to assess the perceptions of HPV vaccination among healthcare university students in Okayama City, Japan, with the goal of promoting HPV vaccination in the future., Methods: The study enrolled 168 students (94 male students and 74 female students, median age: 20 (minimum: 18, maximum: 27)) from a healthcare university in Okayama, Japan. Data collected included sex, age, year, HPV vaccination status, knowledge about HPV vaccination, and cervical cancer screening status (for female students). Participants completed self-administered questionnaires on their perceptions of HPV vaccination. The responses were analyzed using text mining., Results: The HPV vaccination rate among female participants was 16.2% (12 out of 74). Of the respondents, 43.6% of male respondents and 52.7% of female respondents knew that HPV causes cervical cancer. Text mining revealed that among the female respondents, the most frequently used words were "think", followed by "vaccine", "side effects", "vaccination", and "frightening". Distinctive words among female respondents, especially those who haven't been vaccinated, include knowing the term "HPV," understanding that HPV causes cervical cancer, and for those who haven't had screenings, terms like "side effects" and " frightening" were common., Conclusion: Among female students at the healthcare university, the HPV vaccination rate was thought to be comparatively low. Among those who had not received the HPV vaccine, it was particularly noted that they knew the term "HPV," were aware that HPV caused cervical cancer, and for those who had not undergone screenings, providing accurate information about "side effects" and " frightening" seemed necessary., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study. Experimental Research on Human Subjects at Okayama Healthcare Professional University issued approval 0091. Animal subjects: All authors have confirmed that this study did not involve animal subjects or tissue.

The Global Leadership Initiative on Malnutrition (GLIM) criteria recommends using race- and sex-adjusted cutoff values for reduced muscle mass (RMM), but the only cutoff values available for Asians are the skeletal muscle mass index (SMI) established by the Asian Working Group for Sarcopenia (AWGS). This retrospective study aimed to develop and validate cutoff values for the fat-free mass index (FFMI) and arm circumference (AC) of Asians, and to investigate the association between GLIM malnutrition and prognosis. A total of 660 patients with primary gastrointestinal (GI) and hepatobiliary-pancreatic (HBP) cancers who underwent their first resection surgery were recruited and randomly divided into development and validation groups. The FFMI and AC cutoff values were calculated by receiver operating characteristic curve analysis for the AWGS SMI as the gold standard. The cutoff values for each RMM were used to diagnose malnutrition on the basis of GLIM criteria, and the survival rates were compared. The optimal FFMI cutoff values for RMM were 17 kg/m 2 for men and 15 kg/m 2 for women, and for AC were 27 cm for men and 25 cm for women. In the validation group, the accuracy of the FFMI and AC cutoff values to discriminate RMM were 85.2% and 68.8%, respectively. Using any of the three measures of RMM, overall survival rates were significantly lower in the GLIM malnutrition group. In conclusion, the cutoff values for the FFMI and AC in this study could discriminate RMM, and GLIM malnutrition using these cutoff values was associated with decreased survival.

We present an unusual case of a delayed right ventricular perforation by a single standard-caliber implantable cardioverter-defibrillator lead, which manifested 14 days after implantation. Multidetector computed tomography could clearly display the lead perforation, and allow for identification of the associated sequelae such as pericardial effusion and planning the lead extraction strategy.

Parainfluenza virus uncommonly causes fatal giant cell pneumonia in immunocompromised infants and children. To our knowledge, this is the first adult case of parainfluenza virus pneumonia. A 77-year-old woman who was diagnosed as having small-cell carcinoma of the lung underwent chemotherapy. She died of lung edema. Analysis of her serum showed antibodies to parainfluenza virus types 2 and 3 at titers of 1:64 and 1:128, respectively. The postmortem examination revealed giant cell pneumonia, in which giant cells and detached alveolar lining cells had intracytoplasmic inclusions. On electron microscopic examination, the intracytoplasmic inclusions contained fuzzy-form nucleocapsids.
