Characteristics of Top-Searched Individuals in Japan's Yen for Docs Conflicts of Interest Database During the COVID-19 Pandemic.

Purpose Transparency in healthcare has led to increased public disclosure of doctors' conflicts of interest, with the "Yen for Docs Database" in Japan emerging as a pivotal source. Nevertheless, there remains ambiguity regarding the backgrounds and influence of highly-searched persons, especially during the COVID-19 pandemic. The primary objective of this study was to examine if the database was utilized for its intended purpose in 2021, a year marked by the introduction of vaccines and treatments, the addition of new COVID-19-related data, and the frequent appearances of expert statements in various media outlets. Methods We conducted a descriptive analysis on the 10 most frequently searched individuals in the "Yen for Docs Database" between August 27 and September 23, 2021, and determined the amount of money they received from pharmaceutical companies and other organizations over the four-year period between 2016 and 2019. To characterize frequently searched individuals' academic profiles and appearances in the mass media, we identified their h-index and affiliation, their activity on Twitter, and the number of TV appearances. Results There were 72,904 searches during the study period, with the top person accounting for 4,905 of those searches. All top 10 were male, mostly affiliated with universities and specialists in infectious diseases or related fields. Their median number of COVID-19 articles was five, and the median h-index was 34. Four of these top 10 had Twitter accounts, with followers ranging from 12,000 to 195,000. The median amount received from pharmaceutical entities over four years was $154,930, ranging from $809 to $705,502. Conclusions In the Yen for Docs Database, a significant portion of searches during the COVID-19 pandemic was concentrated on a selected group of healthcare professionals with considerable payments over the years, and they exhibited prominent academic and media profiles. These observations highlight the need for more transparent conflicts of interest disclosure among physicians with public visibility.

Observational study of financial and non-financial conflicts of interest among the Japanese government advisory board members concerning coronavirus disease 2019.

This cross-sectional analysis aimed to assess the extent of conflicts of interest among the Japanese government coronavirus disease 2019 (COVID-19) advisory board members and elucidate the accuracy of conflicts of interest (COI) disclosure and management strategies. Using the payment data from all 79 pharmaceutical companies in Japan between 2017 and 2019 and direct research grants from the Japanese government between 2019 and 2020, we evaluated the extent of financial and non-financial COI among all 20 Japanese government COVID-19 advisory board members. The Ethic Committee of the Medical Governance Research Institute approved this study. Japanese government COVID-19 advisory board members were predominantly male (75.0%) and physicians (50.0%). Between 2019 and 2020, 2 members (10.0%) received a total of $819,244 in government research funding. Another 5 members (25.0%) received $532,127 in payments, including $276,722 in personal fees, from 31 pharmaceutical companies between 2017 and 2019. The average value of the pharmaceutical payments was $9155 (standard deviation: $12,975). Furthermore, neither the Ministry of Health, Labor, and Welfare nor the Japanese Cabinet Secretariat disclosed financial or non-financial COI with industry. Additionally, the government had no policies for managing COI among advisory board members. This study found that the Japanese government COVID-19 advisory board had financial and non-financial COI with pharmaceutical companies and the government. Furthermore, personal communication received as part of this research indicated that there were no rigorous COI management strategies for the COVID-19 advisory board members. Any government must ensure the independence of scientific advisory boards by implementing more rigorous and transparent management strategies that require the declaration and public disclosure of all COI.

Guillain-Barre Syndrome After COVID-19 Vaccination: A Secondary Analysis of Domestic Safety Data by the Japanese Government.

Purpose The purpose of this study was to figure out the risk of Guillain-Barre syndrome (GBS) after coronavirus disease 2019 (COVID-19) vaccination, which has been reported as a rare adverse reaction. Methods Elucidating the characteristics, we performed a secondary analysis of the cases from February 2020 through January 2022, based on the publicly available spontaneous adverse reaction reports in Japan. Results We identified 115 cases, and all were after messenger RNA (mRNA) vaccination. Of all the cases, 69 (60.0%) were female and 44 (38.2%) were older than 65 years old. Severe GBS was reported by 38 males (median age 61.5 years) and 51 females (median age 55 years). The median interval from vaccination to the onset of symptoms was eight days for males and four days for females. Sequelae were reported in 18 patients (7 males, median age 81 years; 11 females, median age 51 years), 11 of whom were older than 65 years old. The estimated incidence was about 0.0001% (0.000058% for the Pfizer vaccine and about 0.000046% for the Moderna vaccine, respectively). Conclusions Spontaneous reports would have various biases, the incidence of GBS after mRNA vaccination was as low as in other existing vaccination programs, and it is important not to interpret that risk expansively.

Eleven-Year Trend of Drug and Chemical Substance Overdose at a Local Emergency Hospital in Japan.

PURPOSE: The purpose of this study was to investigate long-term trends of overdose in the emergency department of a regional core hospital in Sendai, Miyagi Prefecture, Japan, and to identify patient characteristics as well as drugs and chemicals associated with overdose. METHODS: Patients who visited the emergency department from January 1, 2010, to December 31, 2020, and were diagnosed with a drug or chemical overdose were included in the study. We conducted a descriptive analysis based on the data collected. RESULTS: In total, 577 patients (mean 38.4 years old, female 75.0%) were considered, and 16.8% had a history of repeated overdose. The number of patients during the study period showed a downward trend, with slight increases in 2012 and 2020. In addition, the top four drugs suspected of causing overdose were over the counter (OTC) antipyretic analgesics and cold medicines (N=97), followed by flunitrazepam (N=80), etizolam (N=72), and brotizolam (N=70). CONCLUSION: There was a decreasing trend in overdose, and OTC medicines, sedatives, and anxiolytics were the primary medications causing overdose. OTC antipyretic analgesics and cold medicines were the most common suspected overdose drugs, with an increasing trend in the later years.

Oral administration of the amino acids cystine and theanine attenuates the adverse events of S-1 adjuvant chemotherapy in gastrointestinal cancer patients.

BACKGROUND: Nutritional therapy is used to reduce the adverse events (AEs) of anticancer drugs. Here, we determined whether the amino acids cystine and theanine, which provide substrates for glutathione, attenuated the AEs of S-1 adjuvant chemotherapy. METHODS: Patients scheduled to receive S-1 adjuvant chemotherapy were randomized to the C/T or the control groups. The C/T group received 700 mg cystine and 280 mg theanine orally 1 week before the administration of S-1, which then continued for 5 weeks. Each group received S-1 for 4 weeks. Blood sampling was performed and AEs were evaluated (CTCAE ver. 4.0) before and after the administration of S-1. S-1 was discontinued when AEs ≥ grade 2 occurred. RESULTS: The incidences of AEs of any grade and those over grade 2 were lower in the C/T group than in the controls. The incidence of diarrhea (G ≥ 2) was significantly less (p < 0.05) in the C/T group (3.1 %) than in the controls (25.8 %). The duration and completion rate of the S-1 adjuvant chemotherapy were significantly longer (p < 0.01) and higher (p < 0.01), respectively, in the C/T group (complete ratio: 75.0 %, duration: 24.8 ± 5.8 days) than in the controls (complete ratio: 35.5 %, duration: 20.0 ± 7.7 days). CONCLUSIONS: The oral administration of cystine and theanine attenuated the AEs of S-1 adjuvant chemotherapy and increased the S-1 completion rate, suggesting that cystine and theanine is a useful supportive care for chemotherapy.

Impacts of the Great East Japan Earthquake on diabetic patients.

AIMS/INTRODUCTION: We investigated impacts of the Great East Japan Earthquake on diabetic patients and characterized those with disaster-susceptible diabetes. MATERIALS AND METHODS: We enrolled 497 diabetic patients who had been followed at hospitals in devastated areas. We collected metabolic parameters prospectively, 1 and 3 months after the earthquake, and retrospectively for pre-earthquake time-points. Questionnaire surveys were carried out regarding earthquake-related damage and post-earthquake lifestyle alterations. Available data were analyzed to examine associations with post-earthquake glycosylated hemoglobin alterations. RESULTS: The mean glycosylated hemoglobin level of the participants was not elevated at 1 month, and was significantly decreased at 3 months as compared with the pre-earthquake glycosylated hemoglobin. There were no significant differences in earthquake-related damage or lifestyle alterations between the improved and worsened glycemic control groups according to the data obtained from the questionnaire survey. As reported, fasting serum C-peptide levels were significantly lower in the worsened glycemic control group (P < 0.05). Notably, plasma noradrenaline levels were significantly higher in the worsened glycemic control group (P < 0.05). Furthermore, at 1 month after the earthquake, the plasma noradrenaline level was significantly higher in the low C-peptide group (fasting serum C-peptide <1.0 ng/mL) than in the high C-peptide group (fasting serum C-peptide ≥1.0 ng/mL), but this difference had disappeared by 3 months after the earthquake. These findings show that post-earthquake plasma noradrenaline levels were temporarily increased in the low C-peptide group. CONCLUSIONS: Sympathetic nerve activation might be elicited more easily in subjects with lower endogenous insulin secretory capacity, and could be involved in the mechanism underlying post-earthquake worsening of glycemic control.

[BASELINE SCREENING USING INTERFERON-GAMMA RELEASE ASSAY SUGGESTS AN INCREASED RISK OF MYCOBACTERIUM TUBERCULOSIS INFECTION AMONG EMPLOYEES IN A JAPANESE GENERAL HOSPITAL].

OBJECTIVES: This retrospective study aimed to assess the risk of tuberculosis infection for the employees of a Japanese hospital using baseline interferon-gamma release assay (IGRA). The risk was defined as exposure to the hospital environment. METHODS: In total, 870 hospital employees including 161 new employees, 582 for baseline assay, and 127 for contact examination (709 subjects in the post-employment group) were examined from December 2010 to April 2012. The new employees were considered as the "non-exposure" group, whereas the post-employment group was considered as the "exposure" group. Multiple logistic regression analyses were used to calculate the odds ratio (OR) for IGRA positivity, adjusted for gender, smoking history, and alcohol intake (model 1), and for years of employment (model 2). RESULTS: The exposure group was significantly associated with an increased risk of positive IGRA results, even when adjusted for years of employment (OR: 4.1; 95% confidence interval: 1.4-17.6; P = 0.007). Subgroup analyses stratified by profession indicated a significantly increased OR for laboratory technicians, doctors, and nurses in both models. No correlation was observed between the length of employment and IGRA positivity. CONCLUSION: Exposure to the hospital environment increased the risk of tuberculosis infection for employees irrespective of the length of employment. Laboratory technicians, doctors, and nurses were at the highest risk of infection.

Day-to-day variability in home blood pressure is associated with cognitive decline: the Ohasama study.

Although an association between high blood pressure and cognitive decline has been reported, no studies have investigated the association between home blood pressure and cognitive decline. Home blood pressure measurements can also provide day-to-day blood pressure variability calculated as the within-participant SD. The objectives of this prospective study were to clarify whether home blood pressure has a stronger predictive power for cognitive decline than conventional blood pressure and to compare the predictive power of the averaged home blood pressure with day-to-day home blood pressure variability for cognitive decline. Of 485 participants (mean age, 63 years) who did not have cognitive decline (defined as Mini-Mental State Examination score, <24) initially, 46 developed cognitive decline after a median follow-up of 7.8 years. Each 1-SD increase in the home systolic blood pressure value showed a significant association with cognitive decline (odds ratio, 1.48; P=0.03). However, conventional systolic blood pressure was not significantly associated with cognitive decline (odds ratio, 1.24; P=0.2). The day-to-day variability in systolic blood pressure was significantly associated with cognitive decline after including home systolic blood pressure in the same model (odds ratio, 1.51; P=0.02), whereas the odds ratio of home systolic blood pressure remained positive, but it was not significant. Home blood pressure measurements can be useful for predicting future cognitive decline because they can provide information not only on blood pressure values but also on day-to-day blood pressure variability.
