Quality of Life (QOL) is attracting attention as a concept which pursues the humanity of patients in contrast to conventional treatment which mainly consists of treatment for sustaining life. In particular, as senile dementia is one of the diseases for which a complete cure is not available to date and for which the main goal of medical treatment and care is improvement in QOL, appropriate evaluation of the effectiveness of treatment for elderly people with dementia cannot be employed without evaluating their QOL.
As well, in the field of pharmacoepidemiology, with the development of antidementia drugs for Alzheimer's disease (AD), utilization of a QOL scale in evaluating drug efficacy has become an important subject. Considering the characteristics of dementia, it is not necessarily easy to evaluate how much QOL improvement antidementia drugs bring about, because many patients have difficulty in evaluating themselves. Therefore, in addition to QOL evaluation, utilizing objective evaluation by observing patients'behavior or the scale measuring the patients'preferences should be examined.
Furthermore, maintaining QOL of caregivers is an important issue as this is closely related with QOL of patients themselves. To care for elderly people with dementia, a caregiver such as a patient's family member shoulders significant mental/physical burden, which could lead to “collapse by caring”. Therefore, in evaluating antidementia drugs, it is necessary to take QOL of caregivers as well as the patients themselves into consideration.

OBJECTIVESThe purposes of this paper were to evaluate the serum leptin levels in healthy adolescents and to establish standard age variation curves.

METHODSNine hundred six (414 boys and 492 girls) healthy adolescents were investigated. The maximum increment age in height (MIA) was identified in 124 boys and 130 girls. The menarcheal age (MA) was obtained for 130 girls. Fasting leptin levels were measured by enzyme immunoassay. The MIA was calculated by proportional allotment of yearly height increments.

RESULTSSerum leptin levels did not change in boys and girls from the ages of 9 to 11. They decreased after the age of 11 in boys, while they increased in girls. Stepwise multiple regression analysis revealed that serum leptin levels were closely related to pubertal stage. The levels decreased remarkably after MIA in boys and increased remarkably after MA in girls. We drew standard age variation curves of serum leptin levels by calculating the 25th, 50th and 75th percentiles for each age in both boys and girls. The percentile curves for boys were divided into pre-MIA and post-MIA curves. Those for girls were divided into pre-MA and post-MA curves.

CONCLUSIONWe have devised a potentially useful method for evaluating serum leptin levels in adolescents considering the effects of gender and growth.

We report a case of refractory cancer pain that was successfully treated with opioid switching by adding methadone to the preceding opioid. A 38-year-old man had severe epigastric pain and back pain because of paraaortic lymph node metastasis of a gastroesophageal junctional carcinoma. His pain was treated with continuous intravenous morphine administration and the frequent use of a rescue dose. When the morphine dose was increased, respiratory depression developed; thus, his pain was considered refractory to the morphine, and methadone was added on. The pain was relieved after initiating methadone, and the frequency of the rescue dose was markedly decreased. The methadone dose was gradually increased in parallel, and the morphine dose was reduced and finally discontinued. No methadone-induced side effects were noted, and the patient was discharged with good analgesia. In our case, adding methadone without decreasing the preceding opioid dose under strict monitoring made it possible to stably switch the opioid without increasing pain.

The purpose of this study was to clarify the changes in the sense of difficulty hospital staff felt toward palliative care before and after a palliative care team of the pediatric hospital started in-hospital consultation. A self-administered questionnaire about the difficulty, consisting of 21 items in five areas, was used to conduct a survey in 2015 for the pre-consultation period, and in 2018 for the post-consultation period. Responses were obtained from 222 people in the pre-consultation period (response rate of 70.9%) and from 384 people in the post-consultation period (response rate of 87.3%). Over 70% of the respondents were nurses and midwives. A lower sense of difficulty was observed in three of the items including “relief of painful symptoms”, “family care during caregiving”, and “support when oneself and surrounding staff feeling inadequate and lost”. Further, a significant decrease was observed in the sense of difficulty in six items reported by nurses and midwives in departments receiving the interventions. Eleven of the 16 cases in which the palliative care team intervened involved multiple requests for intervention for 2 patients with pain control difficulties, suggesting that the consultation activities contributed to the decrease in the sense of difficulty experienced by nurses and midwives.

Real-world data (RWD), such as a health insurance claim database and electronic medical record database, which records daily medical care information, is one of the most important data sources in pharmacoepidemiological studies. In Japan, a post-marketing database study has been added as a new category of post-marketing surveillance since April 2018. It is expected that the post-marketing database studies will be conducted in the actual risk management plan； however, at this point, few have reached the stage of publishing study results. On the other hand, overseas, many database research results using RWD have already been reported. Although it is necessary to keep in mind that there are differences in the characteristics of the databases (e.g., data contents, structures) and the differences in the medical environment between overseas and Japan, we think that critically reviewing these reports has a reference value for the planning, execution, and interpretation of the results in performing post-marketing database studies in Japan. The purpose of this report is to examine the characteristics and cautions of the database studies through a critical review of published articles of overseas RWD studies and to make recommendations that are useful for conducting post-marketing database studies in Japan. We hope this article will become a help in the planning and implementation of future post-marketing database studies.

Purpose: Palliative care implementation should take into account the perceptions and acceptability of healthcare providers. This study aimed to identify physicians’ perceptions of palliative care and barriers to palliative care practice in the critical care setting. Methods: A nationwide, self-administered questionnaire was distributed to physicians working in intensive care units, and free-text data were qualitatively analyzed. Results: The questionnaire was sent to 873 respondents, and 436 responded (50% response rate). Of these, 95 (11%) who responded to the open-ended sections were included in the analysis. Conclusion: Japanese physicians working in ICUs recognized that palliative care was their role and practiced it as part of their usual care. They felt, however, that the practice was difficult and not sufficient. Barriers to practice included the lack of human resources and availability of palliative care teams, and the lack of uniformity in the perception of palliative care in the critical care setting.
