RESUMO
The Japan Diabetes Society and the Japan Cancer Association launched a joint committee and published their "First Joint Committee Report on Diabetes and Cancer" in 2013, compiling recommendations for physicians and health-care providers as well as for the general population. In 2016, the "Second Joint Committee Report on Diabetes and Cancer" summarized the current evidence on glycemic control and cancer risk in patients with diabetes. The current "Third Joint Committee Report on Diabetes and Cancer", for which the joint committee also enlisted the assistance of the Japanese Society of Clinical Oncology and the Japanese Society of Medical Oncology, reports on the results from the questionnaire survey, "Diabetes Management in Patients Receiving Cancer Therapy," which targeted oncologists responsible for cancer management and diabetologists in charge of glycemic control in cancer patients. The results of the current survey indicated that there is a general consensus among oncologists and diabetologists with regard to the need for guidelines on glycemic control goals, the relevance of glycemic control, and glycemic control during cancer therapy in cancer patients.

OBJECTIVES: Comorbidities are associated with a high burden of disease in people living with HIV (PLWH). The objective was to investigate the prevalence of chronic comorbidities and use of co-medications in PLWH in Japan. METHODS: This study retrospectively analysed clinical information from PLWH receiving antiretroviral therapy (ART) between April 2009 and March 2019. Demographic characteristics, numbers and types of chronic comorbidities, and numbers and types of non-ART co-medications, were described by age groups. The source of data was the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB). RESULTS: Overall, 28 089 PLWH (male 91.9%) who used ART were identified. Out of 28 089 PLWH, 81.5% had at least one chronic comorbidity. The numbers of AIDS-defining cancers and non-AIDS-defining cancers in this Japanese cohort were 2432 (8.7%) and 2485 (8.8%), respectively. The cumulative burden of comorbidities including non-AIDS-defining cancer increased with age. Changes in trend between 2009 and 2019 were observed, including a higher proportion of PLWH diagnosed at ≥ 70 years old [2019 (4.7%) vs. 2009 (2.4%)] and a decreasing percentage of patients with AIDS-defining cancers (down from 6.3% to 4.8% between 2009 and 2019). The most common co-medications during the most recent 3-month period were lipid-regulating/anti-atheroma preparations (11.3%), antacids, antiflatulents and anti-ulcerants (9.6%), and agents acting on the renin-angiotensin system (8.1%). The three most common therapeutic categories of co-medications during the study period were antacids, antiflatulents and anti-ulcerants (35.0%), systemic antihistamines (33.7%) and psycholeptics (27.1%). More than 30% of PLWH aged > 40 years used at least one co-medication in a 3-month period, while more than half of PLWH aged > 30 years had at least one co-medication prescribed concomitantly for a total of ≥ 90 days during the study period, and the numbers of co-medications used were greater in the older age groups. CONCLUSIONS: The burden of chronic comorbidities and co-medication were found to be greater in older, as compared to younger patients, among 28 089 PLWH in a nationwide study in Japan. This finding suggests the need to identify elderly PLWH and to appropriately manage their HIV and comorbidities.

BACKGROUND: The prognosis of Philadelphia chromosome-negative myeloproliferative neoplasms is relatively favorable, but the quality of life can be severely affected by myeloproliferative neoplasm-related symptoms such as fatigue, pruritus, night sweats, bone pain, fever and weight loss. In this study, we administered hochuekkito, a traditional herbal medicine, to patients with myeloproliferative neoplasms and investigated whether there was a reduction in myeloproliferative neoplasm-related symptoms. METHODS: We conducted a randomized parallel-group pilot study. Patients were assigned to a hochuekkito administration or non-hochuekkito administration group. Myeloproliferative neoplasm-related symptoms based on Myeloproliferative Neoplasm Symptom Assessment Form total symptom score and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 were examined before hochuekkito administration and 4 and 8 weeks after administration. RESULTS: Among the 42 patients included in the analysis, 21 were assigned to the hochuekkito group and 21 were assigned to the control group. After administering hochuekkito, the median values of Myeloproliferative Neoplasms Symptom Assessment Form total symptom score at 4 and 8 weeks in the hochuekkito group demonstrated a decreasing trend; however, the difference between the two groups was not significant. CONCLUSIONS: In this study, we were unable to demonstrate significant differences between the hochuekkito and control groups in terms of the efficacy of hochuekkito in treating myeloproliferative neoplasm-related symptoms. However, there were cases that presented prominent improvement in symptoms in the hochuekkito group. The only reported adverse event was grade 1 impaired hepatic function. Therefore, hochuekkito might be a therapeutic option for patients with severely affected quality of life due to myeloproliferative neoplasm-related symptoms.

OBJECTIVES: This study aimed to determine whether the current syphilis resurgence in Japan is attributable to incident syphilis in people living with HIV (PLWH). METHODS: This observational, retrospective, population-based study used data from the Japanese National Database. Data were extracted for PLWH who received antiretroviral treatment between January 2009 and December 2018. Using these data, along with the annual number of PLWH and syphilis diagnoses in the total population of Japan acquired from the National Institute of Infectious Diseases, the fraction of PLWH with syphilis compared to the total number of syphilis patients reported each year was calculated. RESULTS: There was a dramatic increase in syphilis cases during the study period. However, the incidence of syphilis in PLWH was stable during 2010-2018; the fraction of PLWH with newly diagnosed syphilis remaining at approximately 2% of the total PLWH cases in Japan each year. The proportion of newly diagnosed syphilis cases in PLWH decreased during the study period and accounted for <10% of the total syphilis cases in Japan since 2016 (14.9% in 2015 to 9.5% in 2016 and 5.9% in 2018). An increasing trend in the number of newly diagnosed syphilis cases in PLWH aged >50 years was observed (7.4% in 2010 to 10.4% in 2014 and 14.9% in 2018). CONCLUSIONS: The recent dramatic increase in syphilis cases in Japan was not seen in PLWH. Thus, the resurgence of syphilis in Japan cannot be attributed to its transmission in the PLWH population.

Early treatment of HIV infection depends on timely diagnosis, but many persons living with HIV/AIDS (PLWHA) are unaware of their infection. Though many patients seeking medical attention for sexually transmitted diseases have HIV, many patients' HIV co-infection is undiagnosed in Japan. This is the first report to analyze the timing of syphilis infection in PLWHA of all ages through the use of the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), containing clinical data of the largest group of HIV-positive patients available in Japan. Overall, 1521 PLWHA (male 93.2%) newly diagnosed and started on antiretroviral therapy were identified in 2016, and 646 (42.5%) patients had a diagnosis of syphilis between 2011 and 2018. Although 100 patients were diagnosed with syphilis before their HIV diagnosis, only 17 (17.0%) had been tested for HIV. Over 50 patients per year became infected with syphilis even after their HIV diagnosis (2017, n = 65 (4.3%); 2018, n = 58 (3.8%)). Although early diagnosis of HIV infection is important, most syphilis patients in Japan had not been properly tested for HIV infection. Since a certain number of HIV patients developed syphilis after HIV diagnosis, education for newly diagnosed HIV patients is important.

GOAL: The goal of this study was to investigate the relationship between Helicobacter pylori (H. pylori) infection and short-segment and long-segment Barrett's esophagus (SSBE and LSBE). BACKGROUND: H. pylori infection is reported to be inversely associated with Barrett's esophagus (BE) in western countries. However, the impact of BE segment length on the association between BE and H. pylori infection has scarcely been investigated. MATERIALS AND METHODS: The study subjects were 41,065 asymptomatic Japanese individuals who took medical surveys between October 2010 and September 2017. Using this large database of healthy Japanese subjects, we investigated the association between H. pylori infection and SSBE/LSBE. We used multivariable logistic regression analysis to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Among the study subjects, 36,615 were eligible for the analysis. H. pylori seropositivity was significantly associated with a lower rate of LSBE (OR: 0.42; 95% CI: 0.16-0.91) and a higher rate of SSBE (OR: 1.66; 95% CI: 1.56-1.78) after multivariate adjustment. In the subgroup analysis, H. pylori seropositivity was significantly associated with a high rate of SSBE in subjects without reflux esophagitis (RE) (OR: 1.73; 95% CI: 1.61-1.85). However, H. pylori seropositivity was not associated with SSBE in subjects with RE (OR: 1.07; 95% CI: 0.84-1.37). CONCLUSION: In a Japanese population, H. pylori infection was inversely associated with LSBE but significantly associated with SSBE only in subjects without RE. H. pylori may be a risk factor for SSBE, especially in individuals without RE.

BACKGROUND: Reflux esophagitis (RE) and absence of Helicobacter pylori (non-H. pylori) are considered to be associated with the progression to long-segment Barrett's esophagus (LSBE). However, it is difficult to assess this association because RE and H. pylori status can change during follow-up. Additionally, the association between H. pylori eradication and LSBE remains unclear. METHODS: A total of 11,493 asymptomatic Japanese subjects who underwent medical check-ups and were endoscopically diagnosed with short-segment Barrett's esophagus (SSBE) between May 2006 and December 2015 were enrolled. The hazards of progression to LSBE were compared between time-varying RE and H. pylori infection/eradication by time-dependent multivariable Cox proportional hazards models. RESULTS: A total of 7637 subjects who underwent additional medical check-ups after being diagnosed with endoscopic SSBE were analyzed. Subjects with RE and without current/past H. pylori infection were strongly associated with a higher rate of progression to LSBE (adjusted hazard ratio [HR]: 7.17, 95% confidence interval [CI]: 2.48-20.73, p < 0.001 for RE and non-H. pylori vs. non-RE and H. pylori groups). Subjects with H. pylori had a lower rate of progression to LSBE (adjusted HR: 0.48, 95% CI: 0.22-1.07, p = 0.07 for H. pylori vs. non-H. pylori). Hazards of progression to LSBE were still lower in the H. pylori eradication group than that of the non-H. pylori group (adjusted HR: 0.51, 95% CI: 0.18-1.46, p = 0.21). CONCLUSIONS: RE and non-H. pylori were associated with the progression to LSBE, considering the changes in exposures. H. pylori infection was associated with the prevention of the development of LSBE irrespective of RE. The environment preventive of the development of LSBE persists for at least a few years after H. pylori eradication.

Pneumococcal vaccination has been shown to reduce occurrence of invasive pneumococcal diseases in elderly patients. In this study, we investigated the real-world efficacy of pneumococcal vaccination implemented in elderly individuals in Japan. We reviewed the in-patient database of Juntendo University Hospital and selected elderly patients (≥65 years-old) who had received in-patient care in the general medicine department during 2014-2018. A total of 1355 patients were retrospectively enrolled and comprised of 1045 unvaccinated and 315 vaccinated elderly individuals. Prior vaccination was found associated with all-cause shorter hospital stays (adjusted RR = 0.66, 95% CI = 0.57 to 0.76) and less medical expenditure (adjusted RR = 0.76, 95% CI = 0.66 to 0.87) compared with no vaccination, as well as protection for all-cause in-hospital mortality (adjusted OR = 0.42, 95% CI = 0.22 to 0.83). The association of shorter hospital stays and less medical expenditure with vaccination was also observed in the context of pneumonia, although no altered risk in mortality was observed. In conclusion, this study is one of the first reporting real-world data after the initiation of pneumococcal vaccination program in 2014 in Japan. The national PPV23 vaccination program contributed to the reduction of all-cause in-patient days, mortality, and medical expenses in the elderly aged ≥65 years. Further data is warranted to evaluate the contribution from influenza vaccination and protein-conjugate based pneumococcal vaccine.

Pneumonia is the third most common cause of death in Japan. Low vaccination rates are thought to be related to low levels of public subsidy. Since 2014, the Japanese government has offered subsidies through a 5-year national routine vaccination program of the 23-valent pneumococcal polysaccharide vaccine (PPV23) for older adults at age ≥65 years with 5-year age intervals. We previously reported that, 2 years into the 5-year program, the estimated vaccination rate was 40.6% at the end of 2015, a significant increase compared with periods before the program introduced. Here, we present an update on the estimated vaccination coverage of the 5-year national routine vaccination program at the end of 2018. The PPV23 vaccination rates were calculated by dividing the cumulative amount shipped to each municipality by the population aged ≥65 years. At the end of 2018, the completion of the 5-year national immunization program, the estimated cumulative vaccination rate was 74%. Stepwise regression analysis revealed that the annual PPV23 vaccination rate significantly increased after 2014 (from 2 to 5% prior to 2014, to 10-11% after 2014), and remained steady for 2014-2018. Our findings suggest that the 5-year national routine vaccination subsidy program was successful in achieving a steady and higher vaccination rate of PPV23 in Japan.

Glucocorticoids (GCs) have long played a central role in the treatment of systemic lupus erythematosus (SLE), but these drugs have many adverse effects. We will determine whether rapid weekly GC tapering is non-inferior to conventional biweekly tapering in patients with severe SLE. This is a randomized, open-label, multicenter controlled trial. The primary outcome is the relapse-free survival rate at 52 weeks. The main secondary outcome is the prevalence of the Lupus Low Disease Activity State at 52 weeks. The trial will determine the optimal method of tapering GCs in patients with severe SLE.

The 2011 Great East Japan Earthquake was the largest and most catastrophic earthquake and tsunami in Japanese history. The aim of the present study was to evaluate the burden and psychological characteristics of children at 2 years after this catastrophe to allow a better understanding of the situation and the provision of appropriate support. We investigated a cross-sectional study carried out in 2013 by sending a questionnaire to schools located in Miyagi Prefecture to be answered by parents or guardians. The questionnaire included the Strengths and Difficulties Questionnaire (SDQ) to estimate the psychological adaptation of children. Telephone consultations were provided for children with SDQ scores > 16 whose parents or guardians had given consent. From the target population of 12,742, a total of 4,074 responses were received (response rate: 32%), among which, 720 had an SDQ score > 16 and received a telephone consultation. At the time of the telephone consultation, 301 (42%) of the 720 children and parents or guardians showed some type of psychological reaction and were thus classified as "Insufficient recovery". Among these, 230 had not received social support at any point in time, suggesting the need for long-term psychological support. Those who resided in a coastal area tended to show a higher rate of psychological reactions than those in an inland area (27.1% vs. 12.9%, respectively). In conclusion, catastrophic disasters have a long-lasting psychological impact on children, and thus, long-term psychological support may be needed.

Pneumocystis pneumonia (PCP) due to Pneumocystis jirovecii infection is the leading cause of fatal opportunistic infections in immunocompromised patients. We will determine whether a daily sulfamethoxazole-trimethoprim (SMX/TMP) dose of 200/40 mg was non-inferior to 400/80 mg for PCP prevention in patients with systemic rheumatic disease under immunosuppressive therapy. This is a randomized, open-label, multicenter controlled trial. The primary outcome is the rate of PCP prevention at 52 weeks. The secondary outcome is the discontinuation rate of SMX/TMP. The trial will evaluate the optimal dose of SMX/TMP for PCP prevention in patients with systemic rheumatic disease under immunosuppressive therapy.

RESUMO
BACKGROUND: An increased focus on quality and patient safety has led to the evolution of hospitalists. The number of hospitalists covering ward and outpatient care is on the rise in Japan. However, it is unclear what roles hospital workers themselves consider important in their practice. Therefore, this study investigated what hospitalists and non-hospitalist generalists in Japan consider important for the practice of their specialty. METHODS: This was an observational study that included Japanese hospitalists (1) currently working in a general medicine (GM) or general internal medicine department and (2) working at a hospital. Using originally developed questionnaire items, we surveyed the items important to hospitalists and non-hospitalist generalists. RESULTS: There were 971 participants (733 hospitalists, 238 non-hospitalist) in the study. The response rate was 26.1%. Both hospitalists and non-hospitalists ranked evidence-based medicine as the most important for their practice. In addition, hospitalists ranked diagnostic reasoning and inpatient medical management as the second and third most important roles for their practice, while non-hospitalists ranked inpatient medical management and elderly care as second and third. CONCLUSIONS: This is the first study investigating the roles Japanese hospitalists consider important and comparing those to that of non-hospitalist generalists. Many of the items that hospitalists considered important were those that hospitalists in Japan are working on within and outside academic societies. We found that diagnostic medicine and quality and safety are areas that are likely to see further evolution as hospitalists specifically emphasized on them. In the future, we expect to see suggestions and research for further enhancing the items that hospital workers value and emphasise upon.

Medical interviews are expected to undergo a major transformation through the use of artificial intelligence. However, artificial intelligence-based systems that support medical interviews are not yet widespread in Japan, and their usefulness is unclear. A randomized, controlled trial to determine the usefulness of a commercial medical interview support system using a question flow chart-type application based on a Bayesian model was conducted. Ten resident physicians were allocated to two groups with or without information from an artificial intelligence-based support system. The rate of correct diagnoses, amount of time to complete the interviews, and number of questions they asked were compared between the two groups. Two trials were conducted on different dates, with a total of 20 resident physicians participating. Data for 192 differential diagnoses were obtained. There was a significant difference in the rate of correct diagnosis between the two groups for two cases and for overall cases (0.561 vs. 0.393; p = 0.02). There was a significant difference in the time required between the two groups for overall cases (370 s (352-387) vs. 390 s (373-406), p = 0.04). Artificial intelligence-assisted medical interviews helped resident physicians make more accurate diagnoses and reduced consultation time. The widespread use of artificial intelligence systems in clinical settings could contribute to improving the quality of medical care.

BACKGROUND: DNA methylation accumulates in non-malignant gastric mucosa after exposure to pathogens. To elucidate how environmental, methylation, and lifestyle factors interplay to influence primary gastric neoplasia (GN) risk, we analyzed longitudinally monitored cohorts in Japan and Singapore. METHODS: Asymptomatic subjects who underwent a gastric mucosal biopsy on the health check-up were enrolled. We analyzed the association between clinical factors and GN development using Cox hazard models. We further conducted comprehensive methylation analysis on selected tissues, including (i) mucosae from subjects developing GN later, (ii) mucosae from subjects not developing GN later, and (iii) GN tissues and surrounding mucosae. We also use the methylation data of mucosa collected in Singapore. The association between methylation and GN risk, as well as lifestyle and methylation, were analyzed. FINDINGS: Among 4234 subjects, GN was developed in 77 subjects. GN incidence was correlated with age, drinking, smoking, and Helicobacter pylori (HP) status. Accumulation of methylation in biopsied gastric mucosae was predictive of higher future GN risk and shorter duration to GN incidence. Whereas methylation levels were associated with HP positivity, lifestyle, and morphological alterations, DNA methylation remained an independent GN risk factor through multivariable analyses. Pro-carcinogenic epigenetic alterations initiated by HP exposure were amplified by unfavorable but modifiable lifestyle choices. Adding DNA methylation to the model with clinical factors improved the predictive ability for the GN risk. INTERPRETATION: The integration of environmental, lifestyle, and epigenetic information can provide increased resolution in the stratification of primary GN risk. FUNDING: The funds are listed in Acknowledgements section.

BACKGROUND/AIMS: Modest alcohol consumption has been suggested to be protective against alanine amino-transferase activities and ultrasonography-defined fat-ty liver. We aimed to explore the association between alcohol consumption and liver fat content as quantitative-ly determined by computed tomography (CT). METHODOLOGY: One-thousand two-hundred thirty-one Japanese males, aged over 40 years, voluntarily participated ina health check-up program including CT screening in 2009-2010. Exclusion criteria included positivity for the hepatitis B or C virus, abstinent alcoholics and potential hepatotoxic drug intake. Liver fat content, visceral adipose tissue (VAT) and subcutaneous adipose tis-sue were determined by CT. The association between alcohol consumption (g/week) and liver attenuation values (HU) was investigated by multivariate analysis with metabolic syndrome factors, liver enzyme activities and physical activities as covariates. RESULTS: One-thousand one-hundred thirty-eight subjects were eligible for this cross-sectional survey. VAT, triglyceride, glycated hemoglobin and alanine aminotransferase were significant and independent predictors for a decrease of liver attenuation. Alcohol consumption had a significant and independent association with an increase in liver attenuation (correlation coefficient=0.007, 95%CI=0.004-0.011, p<0.001) after adjusting for potential confounding variables. CONCLUSIONS: Alcohol consumption has an inverse association with CT-determined liv-er fat content independent of metabolic syndrome factors, liver enzyme activities and physical activities.

Recent studies have focused on hammering sound analysis during insertion of the cementless stem to decrease complications in total hip arthroplasty. However, the nature of the hammering sound is complex to analyse and varies widely owing to numerous possible variables. Therefore, we performed a preliminary feasibility study that aimed to clarify the accuracy of a prediction model using a machine learning algorithm to identify the final rasping hammering sound recorded during surgery. The hammering sound data of 29 primary THA without complication were assessed. The following definitions were adopted. Undersized rasping: all undersized stem rasping before the rasping of the final stem size, Final size rasping: rasping of the final stem size, Positive example: hammering sound during final size rasping, Negative example A: hammering sound during minimum size stem rasping, Negative example B: hammering sound during all undersized rasping. Three datasets for binary classification were set. Finally, binary classification was analysed in six models for the three datasets. The median values of the ROC-AUC in models A-F among each dataset were dataset a: 0.79, 0.76, 0.83, 0.90, 0.91, and 0.90, dataset B: 0.61, 0.53, 0.67, 0.69, 0.71, and 0.72, dataset C: 0.60, 0.48, 0.57, 0.63, 0.67, and 0.63, respectively. Our study demonstrated that artificial intelligence using machine learning was able to distinguish the final rasping hammering sound from the previous hammering sound with a relatively high degree of accuracy. Future studies are warranted to establish a prediction model using hammering sound analysis with machine learning to prevent complications in THA.

PURPOSE: To identify the current ambiguous status of general medicine (GM) and assess current problems and weaknesses for further development of GM. PATIENTS AND METHODS: This study adopted an observational design. GM practitioners were selected from the mailing lists of two primary professional associations for Japanese GM doctors. We included physicians currently working in a GM department, those self-described as GM doctors, and those board-certified in family medicine or general internal medicine. Respondents replied to survey questions about their sociodemographic data, job descriptions, and the requisite skills for practice. GM doctors' job description and required skills were categorized into "clinical," "management," "education," and "research." Participants (n = 971) were compared based on job descriptions and important skills in each category by facility type, size, and position. RESULTS: "Clinical" was indicated as the most important category for both job description and important skills, followed by "management," "education," and "research." For job description details, "follow-up outpatient" (35.6%) ranked first for "clinical," and "resident education" (57.3%) ranked first for "education." By facility type and size, job description and important skills decreased for clinical and management categories as facility sizes increased; the opposite was true for "education." "Research" was generally rated low. By position, no significant difference was found in effort or importance given to research. CONCLUSION: This study is the first survey on GM physicians across Japan. The results show that while Japanese GM physicians focus on and place importance on clinical practice, they are less involved in research and do not consider research skills to be important. The challenge for the future development of GM lies in research.

To report the status of switch rates and time-to-switch of antiretroviral therapy (ART) regimens by evaluating anchor drug classes and common switching patterns in Japanese people living with human immunodeficiency virus (HIV, PLWH). This cross-sectional cohort study extracted data of 28,089 PLWH from the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), which contains data representing the entire population of Japan. PLWH with first prescription records of ART administered between January 2011 and March 2019 were identified (n = 16,069). The median time-to-switch and switch rates of anchor drug classes were estimated by Kaplan-Meier analysis. Brookmeyer-Crowley and Greenwood methods were used to estimate 95% confidence intervals for switch rates and median days, respectively. Switch rates were compared between anchor drug classes by year using log-rank tests. A total of 3108 (19.3%) PLWH switched anchor drug classes from first to second regimens. Switch rates increased continuously over 8 years for non-nucleoside reverse transcriptase inhibitors (NNRTIs) (14.9-65.5%) and protease inhibitors (PIs) (13.2-67.7%), with median time-to-switch of 1826 and 1583 days, respectively. Integrase strand transfer inhibitors (INSTIs) maintained a low switch rate (3.0-7.6%), precluding median-days calculation. Overall, the majority of patients treated initially with NNRTIs and PIs switched to INSTIs regardless of switching times (< 1 year: 67.3% and 85.9%, respectively; ≥ 1 year: 95.5% and 93.6%, respectively). The foremost switching strategies for first-to-second ART regimens are from NNRTIs or PIs to INSTIs regimens that maintain low switch rates long term. There was no observable difference in trend between sex, age and status of AIDS disease at first ART regimen. INSTIs HIV agents may be the most durable anchor drug class for PLWH receiving ART.
