Original articles in the medical literature should have informative titles, also referred to as declarative titles. A nondeclarative title expresses the study's theme (topic) or, at most, the materials and methods used, whereas an informative title highlights the significance of the study findings (study's significance) and, at the very least, its results. A manuscript is typically organized to cover (i) the theme, (ii) materials and methods, (iii) results, and (iv) conclusion (study's significance). Consequently, a nondeclarative title typically encompasses only the (ii) stage, whereas an informative title extends to the (iii) or (iv) stages. This study underscores the importance of informative titles in medical papers and offers guidance for crafting titles that align with established paper writing fundamentals.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic may have led to an increase in home deaths due to hospital bed shortage and hospital visitation restrictions. This study aimed to examine changes in the proportion of home deaths before and after the COVID-19 pandemic and identify associated factors.

Methods: We used publicly available nationwide data to describe the proportion of home deaths among total deaths from 2015 to 2021. Furthermore, we used municipal-level data to examine the factors associated with the increase in the proportion of home deaths from 2019 to 2021. The dependent variable was the absolute change in the proportion of home deaths from 2019 to 2021. The independent variables included each municipality's 2019 home death percentage, medical and long-term care (LTC) resources divided by the population of older people, population density, and cumulative number of COVID-19 cases. A multivariable linear regression analysis was conducted after the standardization of each variable.

Results: The proportions of home deaths in 2015, 2019, and 2021 were 12.7%, 13.6%, and 17.2%, respectively, indicating a sharp increase in home death rate after the COVID-19 pandemic. In the multivariable linear regression analysis that included 1,696 municipalities, conventional home care support clinics and hospitals (HCSCs) (coefficient [95% confidence intervals (CIs)], 0.19 [0.01-0.37]), enhanced HCSCs (0.53 [0.34-0.71]), home-visiting nurses (0.26 [0.06-0.46]), population density (0.44 [0.21-0.67]), and cumulative COVID-19 cases (0.49 [0.27-0.70]) were positively associated with the increase in home deaths, whereas beds of LTC welfare facilities (-0.55 [-0.74--0.37]) and the proportion of home deaths in 2019 (-1.24 [-1.44--1.05]) were negatively associated with the increase.

Conclusions: During the COVID-19 pandemic, home deaths significantly increased, particularly in densely populated areas with high cumulative COVID-19 cases. HCSCs, especially enhanced HCSCs, are crucial for meeting the demand for home-based end-of-life care.

Introduction: The clinical benefit of hemostasis molecular indicators such as thrombin-antithrombin complex (TAT), soluble fibrin (SF), and prothrombin fragment 1 + 2 (F1+2) for the diagnosis of disseminated intravascular coagulation (DIC) is reported. Recently, novel DIC diagnostic criteria that adopt them were proposed in Japan. Despite the theoretical understanding of their function, the practical use of these markers remains unclear. The present study aimed to provide a descriptive overview of current clinical practice regarding the measurement of hemostasis markers in sepsis management in Japan.

Methods: This retrospective observational analysis used the Japanese Diagnosis Procedure Combination inpatient database containing data from more than 1500 acute-care hospitals in Japan. We identified adult patients hospitalized for sepsis between April 2018 and March 2021. Descriptive statistics for measuring several hemostasis laboratory markers were summarized using patient disease characteristics, hospital characteristic, and geographical location.

Results: This study included 153,474 adult sepsis patients. Crude in-hospital mortality was 30.0%. Frequency of measurement of fibrinogen, fibrin degradation products (FDP), and D-dimer in sepsis patients on admission was 43.2%, 36.1%, and 46.4%, respectively. Novel and specific hemostasis molecular markers such as TAT, SF, and F1+2 were seldom measured (1.9%, 1.7%, and 0.02%, respectively). Hemostasis molecular markers were more frequently measured with progression of thrombocytopenia. Measurement of these clinically favorite hemostasis markers was influenced not only by disease characteristics but also hospital characteristic or geographical location.

Conclusions: Hemostasis molecular markers such as TAT, SF, and F1+2 were rarely measured in clinical settings. Although adopted by several DIC scoring systems, neither fibrinogen, FDP, nor D-dimer was routinely measured.

Introduction: Hepatocellular carcinoma (HCC) is a major global health challenge, being the fifth most prevalent neoplasm and the third leading cause of cancer-related deaths worldwide. Liver transplantation offers a potentially curative approach for HCC, yet the risk of recurrence posttransplantation remains a significant concern. This study investigates the influence of a liver immune status index (LISI) on the prognosis of patients undergoing living-donor liver transplantation for HCC.

Methods: In a single-center study spanning from 2001 to 2020, 113 patients undergoing living-donor liver transplantation for HCC were analyzed. LISI was calculated for each donor liver using body mass index, serum albumin levels, and the fibrosis-4 index. This study assessed the impact of donor LISI on short-term recurrence rates and survival, with special attention to its correlation with the antitumor activity of natural killer (NK) cells in the liver.

Results: The patients were divided into two grades (high donor LISI, >-1.23 [n = 43]; and low donor LISI, ≤-1.23 [n = 70]). After propensity matching to adjust the background of recipient factors, the survival rates at 1 and 3 years were 92.6% and 88.9% and 81.5% and 70.4% in the low and high donor LISI groups, respectively (p = 0.11). The 1- and 3-year recurrence-free survival were 88.9% and 85.2% and 74.1% and 55.1% in the low and high donor LISI groups, respectively (p = 0.02).

Conclusions: This study underscores the potential of an LISI as a noninvasive biomarker for assessing liver NK cell antitumor capacity, with implications for living-donor liver transplantation for HCC. Donor LISI emerges as a significant predictor of early recurrence risk following living-donor liver transplantation for HCC, highlighting the role of the liver antitumor activity of liver NK cells in managing liver malignancies.

Introduction: Even though an MEK inhibitor has been recently launched, neurofibroma still negatively affects the well-being of patients with neurofibromatosis type 1 (NF1). The coronavirus disease 2019 (COVID-19) pandemic resulted in restricted access to medical care. The present study was conducted to investigate the real-world settings of patients with NF1 who underwent surgery with or without restricted medical access during the COVID-19 pandemic.

Methods: Based on data obtained from medical records, the present study examined 123 and 260 patients who underwent surgery for neurofibromas with and without restricted medical access, respectively.

Results: The mean numbers of surgeries performed during the periods with and without restricted medical access were 5.8 and 9.8 per month, respectively, and there were 1.18- and 1.46-fold more female patients than male patients for each group, respectively. Regardless of whether medical access was restricted, the majority of patients who underwent surgery were middle-aged females with multiple or severe neurofibromas and mild extracutaneous symptoms. Tumor burden was the most common reason for surgery. However, cutaneous neurofibromas were more likely to be treated than plexiform neurofibromas under restricted medical access.

Conclusions: Patients with NF1, particularly middle-aged females with severe cutaneous manifestations and mild extracutaneous manifestations, still underwent surgery for neurofibromas regardless of whether medical access was restricted.

Clinical doctors with overwhelming workloads at university or center hospitals may not have sufficient time to allocate for each patient or to consider each patient's personal condition. Retirement may be a good chance to make a new start by becoming a clinical doctor in a smaller institute. Becoming a clinical doctor in a smaller institute may give you satisfaction and happiness different from being a university clinical doctor. I believe that after retirement from a university or big hospital, older clinical doctors should continue to participate in clinical practice for as long as they wish. This may be one of the solutions for providing clinical doctors in the current and coming super-aged Japan.

Background: This study aimed to assess the conclusiveness of Cochrane Reviews (CRs) in oncology nursing.

Methods: We searched systematically for all CRs published in the Cochrane Library in the oncology nursing field between January 2014 and April 2023. We analyzed the difference between conclusive and inconclusive outcomes using the χ² and Mann-Whitney U-tests and identified 430 articles. However, we excluded 385 articles after reviewing their titles and abstracts. We assessed 45 full-text articles for eligibility and identified 32 articles. Of the 32 articles, we extracted 19 interventions.

Results: The overall outcomes were 182 cases, with 51.6% (n = 94) and 48.4% (n = 88) demonstrating conclusiveness and inconclusiveness, respectively. Regarding conclusiveness, 28.0% (n = 51) and 23.6% (n = 43) reported that the studied interventions were effective and ineffective, respectively. We found that studies on interventions related to physical activity and yoga had significantly high rates of conclusive. Compared with inconclusiveness outcomes, conclusive outcomes involved significantly more studies (p < 0.001) and patients (p < 0.001).

Conclusions: Ultimately, these findings reveal that in the oncology nursing field, only 51% of the main outcomes of each nursing intervention in CRs were conclusive.
