Depressive and anxiety symptoms among Japanese cancer survivors: Japan cancer survivorship research project.

BACKGROUND: This study aimed to clarify predictors of depressive symptoms and anxiety symptoms after cancer diagnosis among Japanese cancer survivors (CSs). METHODS: As part of a Japanese cancer survivorship research project commissioned by the Ministry of Health, Labour and Welfare (MHLW) of Japan, we conducted a web-based nationwide survey of CSs in 2018. We analyzed the risk factors for depressive and anxiety symptoms, as measured by the Hospital Anxiety and Depression Scale Japanese version (HADS). RESULTS: Of 1,234 Japanese CSs, mean score of HADS-depression and HADS-anxiety were 4.08 and 4.78, respectively. At the time of the study, the number of CSs with symptoms of depression and anxiety were 111 (9.0%) and 269 (21.8%), respectively. After multivariable analysis, CSs ≥ 60 years old (reference: ≤ 39 years old, odds ratios (OR): 0.39, 95%CI: 0.17-0.90) and those ≥ 10 years from cancer diagnosis (reference: 0-4 years, OR: 0.55, 95%CI: 0.32-0.96) had lower odds for depressive symptoms. And CSs ≥ 60 years old (reference: ≤ 39 years old, OR: 0.27, 95%CI: 0.15-0.49) and those ≥ 10 years from cancer diagnosis (reference: 0-4 years, OR: 0.62, 95%CI: 0.42-0.90) also had lower odds for anxiety symptoms. CSs who received chemotherapy (OR: 1.56, 95%CI: 1.10-2.20) had higher odds for anxiety symptoms. CONCLUSIONS: Based on manifestation of symptoms, CSs who were younger, closer to the time of cancer diagnosis, had advanced-staged cancer, or received chemotherapy may be at higher risk for depressive or anxiety symptoms. Those CSs who have higher risk for depression and anxiety symptoms, should be followed-up more carefully for better cancer survivorship, by medical professionals, companies, and society.

Clinical characteristics of patients with spondyloarthritis and inflammatory bowel disease versus inflammatory bowel disease-related arthritis.

The purpose of this study was to clarify the clinical characteristics of spondyloarthritis (SpA) patients with inflammatory bowel disease (IBD) compared to those without IBD. Furthermore, among patients with SpA and IBD, we aimed to clarify what clinical characteristics lead rheumatologists to diagnose "IBD-related arthritis." Utilizing SpA and psoriatic arthritis (PsA) patients' data from an international, cross-sectional, observational study, we analyzed information on demographics and disease characteristics, dichotomizing patients by IBD status. The presence or absence of IBD was determined based on data collection of treating rheumatologists. Patients with SpA (including PsA) and IBD were also categorized based on treating rheumatologists' definitive diagnosis in regard to SpA type, and compared by whether the patients had IBD-related arthritis or not. Among 4465 SpA patients, 287 (6.4%, 95%CI 5.7-7.2%) were identified with IBD. Compared to SpA patients without IBD, patients with SpA and IBD had a longer diagnostic delay (5.1 vs. 2.9 years, p < 0.001). In patients with SpA and IBD, 111 (38.7%, 95%CI 33.0-44.6%) were diagnosed with IBD-related arthritis. Multivariable analyses showed that HLA-B27 positivity [OR = 0.35, (95%CI 0.15-0.80)], psoriasis [OR = 0.14, (95%CI 0.04-0.50)], IBD as first symptom of SpA [OR = 3.32, (95%CI 1.84-6.01)], and need for IBD-specific treatment [OR = 5.41, (95%CI 2.02-14.50)] were independently associated with the definitive diagnosis of IBD-related arthritis. Collaboration with gastroenterologists is needed to shorten the diagnostic delay in patients with SpA and IBD. The recognition of the factors for the diagnosis of "IBD-related arthritis" may lead to the elucidation of the pathogenesis.

SAPHO syndrome and pustulotic arthro-osteitis.

Synovitis-Acne-Pustulosis-Hyperostosis-Osteitis (SAPHO) syndrome is a rare inflammatory osteoarticular disorder, which encompassed many diseases, including pustulotic arthro-osteitis (PAO). Musculoskeletal manifestations, including osteitis, synovitis, and hyperostosis, are the hallmarks of the SAPHO syndrome and affect a variety of regions of the body. Recent survey indicated that more than 80% of cases of SAPHO syndrome in Japan were PAO, originally proposed by Sonozaki et al. in 1981, whereas severe acne was the most commonly reported skin ailment amongst participants with SAPHO syndrome in Israel. Prevalence of SAPHO syndrome remains unavailable, whereas the prevalence of palmoplantar pustulosis (PPP) was reported to be 0.12% in Japan, and 10-30% of patients with PPP had PAO. SAPHO syndrome and PAO are predominantly found in patients in the third through fifth decades of life, and a female predominance is seen in both groups. The diagnosis is typically made by a rheumatologist or dermatologist. Identification of a variety of the clinical, radiological, and laboratory features outlined, as well as diagnostic criteria, are used to make the diagnosis. Goals of treatment seek to maximize health-related quality of life, preventing structural changes and destruction, and normalizing physical function and social participation. Finally, we review the non-pharmacological and pharmacological managements.

GIANT MEDIASTINAL PARATHYROID ADENOMAS AND MULTIPLE ENDOCRINE NEOPLASIA TYPE 1: A DIAGNOSTIC CONUNDRUM.

Context: Giant parathyroid adenoma (GPA) is a rare entity that is rarer with Multiple endocrine neoplasia type 1 (MEN1) syndrome. Objectives: Describe the clinical presentation, diagnostic difficulties, and management strategy for GPA in MEN1. Methods: We searched Pubmed, SCOPUS and EMBASE for GPA in MEN1 for GPA in association with MEN1. Hereby, we describe index case of largest ever reported GPA. Results: We identified 7 cases of GPA reported till date in association with MEN1. The mean adenoma weight was 7.1 gram. The index case is largest-ever reported GPA (weight 97 gram) in MEN1 presenting with compressive symptoms and mediastinal mass. Incidentally, she was found to have hypercalcemia with increased parathyroid hormone, suggesting primary hyperparathyroidism. The possibilities of an ectopic parathyroid tumor and thymic carcinoid were considered. She also had acromegaloid features, and was found to have a sellar tumor. Subsequently, MENIN gene mutation was identified confirming MEN1 syndrome. Patient underwent trans-sternal excision of the mass weighing 97 grams and confirmed as parathyroid adenoma on histopathologic examination. Conclusion: Despite rarity of ectopic mediastinal parathyroid tumors, calcium profile should be considered as part of work-up of considering varied etiologies of anterior mediastinal mass.

Predictors of resignation and sick leave after cancer diagnosis among Japanese breast cancer survivors: a cross-sectional study.

BACKGROUND: In Japan, 55.5% of breast cancer survivors (BCSs) are of working age, so various perspectives regarding return to work (RTW) after cancer diagnosis need to be considered. Therefore, this study aimed to clarify the risk factors for resignation and taking sick leave (SL) among BCSs in continued employment at the time of diagnosis. METHODS: A web-based retrospective cross-sectional survey was conducted on BCSs using data from a 2018 Japanese national research project (Endo-Han) commissioned by the Ministry of Health, Labour and Welfare of Japan. The subjects were women aged 18-69 years who had been diagnosed with breast cancer for the first time at least 1 year previously. The risk factors for resignation and taking SL after breast cancer diagnosis, including age at diagnosis, education level, cancer stage, surgery, chemotherapy, radiotherapy, employment status, and occupational type, were then analyzed using a logistic regression model. RESULTS: In total, 40 (14.9%) of 269 BCSs quit their jobs at least 1 year after being diagnosed with breast cancer. The results of the multivariable analysis indicated that lower education level (odds ratio [OR]: 3.802; 95% confidence interval [CI]: 1.233-11.729), taking SL (OR: 2.514; 95%CI: 1.202-5.261), and younger age at diagnosis (OR: 0.470; 95%CI: 0.221-0.998) were predictors of resignation. Of 229 patients who continued working, SL was taken by 72 (31.4%). In addition, undergoing surgery was found to be a predictor of taking SL (OR: 8.311; 95%CI: 1.007-68.621). CONCLUSIONS: In total, 40 (14.9%) of 269 BCSs quit their jobs at least 1 year after being diagnosed with breast cancer. The results of this study indicated that younger age, lower education level, and taking SL were predictors of resignation after breast cancer diagnosis.

Analysis of severe psychological stressors in women during fertility treatment: Japan-Female Employment and Mental health in Assisted reproductive technology (J-FEMA) study.

PURPOSE: To identify risk factors for severe psychological stress in women undergoing fertility treatment. METHODS: This cross-sectional, multi-center study was conducted from August to December 2018. We recruited 1672 subjects who completed an anonymous, self-reported questionnaire regarding fertility treatment, conditions at work and home, and psychological stress using K6 score, which estimates psychological distress during the previous 30 days. We further focused our analysis on 1335 subjects who were working when starting fertility treatment. RESULTS: Of 1672 women, mean K6 score (range 0-24) was 4.8 ± 4.4, including 103 women (6.2%) with K6 score ≥ 13 (high K6), and classified as probable severe psychological distress. Multivariate logistic regression analysis showed that high K6 was strongly associated with low annual family income of ≤ USD55,700 (JPY6 million) (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.04-3.42), infertility duration of ≥ 2 years (OR 1.87, 95% CI 1.08-3.25), and no experience of childbirth (OR 2.04, 95% CI 1.05-3.97). Focusing on 1335 working women, 266 (19.9%) experienced resignation from work. High K6 was strongly associated with low family income (OR 2.83, 95% CI 1.52-5.28), cessation of professional duties (OR 2.08, 95% CI 1.05-4.14), infertility-related harassment in the workplace (OR 2.07, 95% CI 1.08-3.98), and perceived difficulties to continue working during fertility treatment (OR 2.94, 95% CI 1.15-7.50). CONCLUSION: Severe psychological stressors in women during fertility treatment included low family income, long infertility duration, childlessness, infertility-related harassment, and perceived difficulty in working conditions or cessation from work. Establishment of mental health care support systems is urgently required in this population.

Search for a Variation of the Fine Structure Constant around the Supermassive Black Hole in Our Galactic Center.

Searching for space-time variations of the constants of Nature is a promising way to search for new physics beyond general relativity and the standard model motivated by unification theories and models of dark matter and dark energy. We propose a new way to search for a variation of the fine-structure constant using measurements of late-type evolved giant stars from the S star cluster orbiting the supermassive black hole in our Galactic Center. A measurement of the difference between distinct absorption lines (with different sensitivity to the fine structure constant) from a star leads to a direct estimate of a variation of the fine structure constant between the star's location and Earth. Using spectroscopic measurements of five stars, we obtain a constraint on the relative variation of the fine structure constant below 10^{-5}. This is the first time a varying constant of nature is searched for around a black hole and in a high gravitational potential. This analysis shows new ways the monitoring of stars in the Galactic Center can be used to probe fundamental physics.

Noneffectiveness of scopolamine for facilitating detection of upper gastrointestinal neoplasia during screening esophagogastroduodenoscopy: propensity score-matched study.

BACKGROUND: Antispasmodics, such as scopolamine, are widely used in several countries prior to diagnostic and screening esophagogastroduodenoscopy (EGD), with the goal of optimizing the detection of minute lesions, typically early gastric cancer (T1 lesions). The aim of this study was to determine whether scopolamine facilitates detection of gastric cancer in the screening setting. METHODS: A propensity score-matched retrospective study was conducted in a tertiary referral medical center in Tokyo, Japan. Consecutive individuals (n = 40 776) underwent screening EGD between January 2011 and May 2016. All outcome lesions were diagnosed with histopathological confirmation. Detection of esophageal cancer, gastric adenoma, duodenal adenoma, and upper gastrointestinal neoplasia (UGIN) were investigated as secondary outcomes. RESULTS: Scopolamine was used in 31 130 patients (76.3 %) and propensity score matching yielded 6625 pairs. Bivariate analysis revealed no significant association between possible confounders (age, sex, overweight, atrophic gastritis, alcohol history, smoking history, midazolam use, endoscopist biopsy rate grade, and gastric cancer in first-degree relatives) and scopolamine use. Lesions detected were 18 gastric cancers, 11 esophageal cancers, 19 gastric adenomas, 6 duodenal adenomas, and 54 UGINs, with no significant association between scopolamine use and lesion detection. CONCLUSIONS: Scopolamine use did not appear to effectively facilitate detection of gastric or esophageal cancer, gastric or duodenal adenoma, and UGIN during screening EGD. Scopolamine should be avoided until its efficacy is confirmed by a randomized controlled trial.

Risk factors for resignation from work after starting infertility treatment among Japanese women: Japan-Female Employment and Mental health in Assisted reproductive technology (J-FEMA) study.

OBJECTIVE: To elucidate the risk factors associated with resignation from work of Japanese women undergoing infertility treatment. METHODS: A total of 1727 female patients who attended a private fertility clinic in Japan participated in the Japan-Female Employment and Mental health in Assisted reproductive technology study. Questions related to demographic, clinical and socioeconomic characteristics were employed in the questionnaire. Out of the 1727 patients, 1075 patients who were working at the time of initiating infertility treatment and felt infertility treatment incompatible with work were included in the analysis. Risk factors for resignation were assessed by using multivariable logistic regression models. RESULTS: Among 1075 working women who started infertility treatment, 179 (16.7%) subsequently resigned. Multivariable-adjusted ORs for resignation in those with lower educational background and infertility for ≥2 years were 1.58 (95% CI: 1.07 to 2.34) and 1.82 (95% CI: 1.15 to 2.89), respectively. The OR for resignation in non-permanent workers undergoing infertility treatment was 2.65 (95% CI: 1.61 to 4.37). While experiencing harassment in the workplace approached significance, lack of support from the company was significantly associated with resignation after starting infertility treatment, with ORs of 1.71 (95% CI: 0.98 to 2.99) and 1.91 (95% CI: 1.28 to 2.86), respectively. CONCLUSION: One-sixth of women resigned after starting infertility treatments. It was found that factors related to education, infertility duration and work environment were significantly associated with resignation. Reducing the physical and psychological burden endured by women, for example, by increasing employer-provided support, is vitally important in balancing infertility treatment with maintenance of work life.

In-hospital mortality associated with the misdiagnosis or unidentified site of infection at admission.

BACKGROUND: Rapid detection, early resuscitation, and appropriate antibiotic use are crucial for sepsis care. Accurate identification of the site of infection may facilitate a timely provision of appropriate care. We aimed to investigate the relationship between misdiagnosis of the site of infection at initial examination and in-hospital mortality. METHODS: This was a secondary-multicenter prospective cohort study involving 37 emergency departments. Consecutive adult patients with infection from December 2017 to February 2018 were included. Misdiagnosis of the site of infection was defined as a discrepancy between the suspected site of infection at initial examination and that at final diagnosis, including those infections remaining unidentified during hospital admission, whereas correct diagnosis was defined as site concordance. In-hospital mortality was compared between those misdiagnosed and those correctly diagnosed. RESULTS: Of 974 patients included in the analysis, 11.6% were misdiagnosed. Patients diagnosed with lung, intra-abdominal, urinary, soft tissue, and CNS infection at the initial examination, 4.2%, 3.8%, 13.6%, 10.9%, and 58.3% respectively, turned out to have an infection at a different site. In-hospital mortality occurred in 15%. In both generalized estimating equation (GEE) and propensity score-matched models, misdiagnosed patients exhibited higher mortality despite adjustment for patient background, site infection, and severity. The adjusted odds ratios (misdiagnosis vs. correct diagnosis) for in-hospital mortality were 2.66 (95% CI, 1.45-4.89) in the GEE model and 3.03 (95% CI, 1.24-7.38) in the propensity score-matched model. The difference in the absolute risk in the GEE model was 0.11 (0.04-0.18). CONCLUSIONS: Among patients with infection, misdiagnosed site of infection is associated with a > 10% increase in in-hospital mortality.

Planning of births and maternal, child health, and nutritional outcomes: recent evidence from India.

OBJECTIVES: In an effort to provide recommendation for maximizing synergy between maternal, infant, and young children's nutrition and family planning in India, this study makes a comprehensive assessment of the effects of the planning of births in terms of timing, spacing and limiting childbearing on maternal and child health outcomes. STUDY DESIGN: This study used the latest National Family Health Survey data of India that is globally known as the Demographic and Health Survey. A robust two-stage systematic random sampling was used for selecting representative samples for measuring demographic and health indicators. METHODS: Maternal and child health outcomes are measured by body mass index (grouped as normal, underweight, and overweight) and anemia for mothers, and stunting, underweight, anemia, and under-five mortality for the children. Logistic regression and Cox proportional hazard models were applied. RESULTS: Women with a higher number of births and among those with first-order births with fewer than 2 years between marriage and first birth, the risk of being underweight and having anemia was significantly higher compared with their counterparts. In addition, the probability of being underweight and risk of stunting, anemia, and mortality was higher among the children from women with a higher number of births and with fewer than 3 years of spacing between births than that of their counterparts. CONCLUSIONS: The findings from this study support the importance of birth planning in improving maternal, child health, and nutritional outcomes. The proper planning of births could help to achieve the Sustainable Development Goal-3 of good health and well-being for all by 2030 in India, where a significant proportion of women still participate in early marriages, early childbearing, and a large number of births with close spacing.

Comparison Between Isotropic 3-Dimensional Fat-Suppressed T2-Weighted Fast Spin Echo (FSE) and Conventional 2-Dimensional Fat-Suppressed Proton-Weighted FSE Shoulder Magnetic Resonance Imaging at 3-T in Patients With Shoulder Pain.

OBJECTIVE: The aims of this study were to compare isotropic 3-dimensional fat-suppressed T2-weighted fast spin echo (FSE) imaging (T2FS) with 2-dimensional fat-suppressed proton-density-weighted FSE imaging (2D-PDFS) and evaluate feasibility of isotropic 3-dimensional FSE shoulder imaging at 3-T magnetic resonance imaging (MRI). METHODS: Seventy-eight patients who underwent shoulder MRI were evaluated. Three-dimensional T2FS and 2D-PDFS were qualitatively graded for delineation of anatomic structures. In quantitative analysis, mean relative signal intensity and relative signal contrast between each structure of the shoulder were compared. RESULTS: Three-dimensional T2FS showed significantly higher scores for rotator cuff (P = 0.020), lower scores for bone (P < 0.001), and higher relative contrast of rotator cuff to fluid (P < 0.001) and labrum to fluid (P < 0.001) in comparison with 2D-PDFS. No significant difference in relative signal intensity of the rotator cuff, labrum, joint fluid, cartilage, and bone marrow was demonstrated. CONCLUSIONS: Isotropic 3-dimensional FSE MRI has similar image quality and diagnostic performance to conventional 2-dimensional sequence in evaluation of the rotator cuff.

Variation in somatic symptoms by patient health questionnaire-9 depression scores in a representative Japanese sample.

BACKGROUND: This study aims to evaluate variation in somatic symptoms by age using patient health questionnaire-9 (PHQ) depression scores, which may be helpful in identifying depression. METHODS: The study evaluated a nationally representative cross-sectional sample of community-dwelling adults in Japan in 2013. We utilized the PHQ to identify risk for depression, with PHQ ≥ 10 defining at least moderate depression. Bivariate and factor analyses were used to capture underlying patterns in self-reported symptoms over a 30 day period; aged-stratified multivariate logistic regression was performed to further explore associations between age, symptoms, and depression. RESULTS: Of 3753 respondents, 296 (8, 95% CI 7.0-8.8) reported a PHQ ≥ 10; 42% of these were male and mean age was 51.7 years old (SD = 18.6). Multivariate analysis showed that presence of fatigue and malaise (OR = 1.7, 95% CI 1.3-2.4) was significantly associated with PHQ ≥ 10. After stratification by age, PHQ ≥ 10 was associated with gastrointestinal complaints among 18-39 year olds (OR = 1.7, 95% CI 1.0-2.9); fatigue and malaise (OR = 1.8, 95% CI 1.1-3.1) among 40-64 year olds; and fatigue and malaise (OR = 1.8, 95% CI 1.1-3.0) as well as extremity pain (OR = 1.7, 95% CI 1.0-2.8) in over 65 year olds. CONCLUSION: Age-related somatic symptom correlates of PHQ ≥ 10 differ across the lifespan. Predominantly gastrointestinal symptoms in younger patients, and generalized fatigue, malaise, and musculoskeletal pain in older groups were observed. In order for screening physicians to proactively identify depression, awareness of age-related somatic symptoms is warranted.

Reassessing the Ecology of Medical Care in Japan.

Studies on ecology of medical care can provide valuable information on how people seek healthcare in a specific geographic area. The objective of this study was to update a 2003 report on the ecology of medical care in Japan, identifying relevant changes in healthcare patterns. We collected information based on a prospective health diary recorded for a month in 2013 (n = 4548; 3787 adults and 797 children) using a population-weighted random sample from a nationally representative panel. We compared our overall and stratified findings with a similar study conducted in 2003. During a one-month period, per 1000 adults and children living in Japan, we estimated that 794 report at least one symptom, 447 use an over-the-counter (OTC) drug, 265 visit a physician's office, 117 seek help from a professional provider of complementary or alternative medicine (CAM), 70 visit a hospital outpatient clinic (60 community-based and 10 university-based), 6 are hospitalized, and 4 visit a hospital emergency department. After adjusting for demographic variables, we found that healthcare seeking behaviors were influenced by age, gender and area of living. Compared with the 2003 study, participants in this study had fewer symptoms, fewer physician and emergency room visits, and less OTC use, but reported higher frequency of CAM use (p < .01 for all). Compared with 2003, reported symptoms, physician visits and OTC use has decreased, while CAM use has increased. Our findings may be useful to policymakers in Japan in a context where healthcare expenditure and a rapidly aging population are two challenging issues.

Step Coalescence by Collective Motion at an Incommensurate Grain Boundary.

Using extended time series scanning transmission electron microscopy, we investigate structural fluctuations at an incommensurate grain boundary in Au. Atomic-resolution imaging reveals the coalescence of two interfacial steps, or disconnections, of different height via coordinated motion of atoms along close-packed directions. Numerical simulations uncover a transition pathway that involves constriction and expansion of a characteristic stacking fault often associated with grain boundaries in face-centered cubic materials. It is found that local atomic fluctuations by enhanced point defect diffusion may play a critical role in initiating this transition. Our results offer new insights into the collective motion of atoms underlying the lateral advance of steps that control the migration of faceted grain boundaries.

Diabetes screening intervals based on risk stratification.

BACKGROUND: Guidelines for frequency of Type 2 diabetes mellitus (DM) screening remain unclear, with proposed screening intervals typically based on expert opinion. This study aims to demonstrate that HbA1c screening intervals may differ substantially when considering individual risk for diabetes. METHODS: This was a multi-institutional retrospective open cohort study. Data were collected between April 1999 to March 2014 from one urban and one rural cohort in Japan. After categorization by age, we stratified individuals based on cardiovascular disease risk (Framingham 10-year cardiovascular risk score) and body mass index (BMI). We adapted a signal-to-noise method for distinguishing true HbA1c change from measurement error by constructing a linear random effect model to calculate signal and noise of HbA1c. Screening interval for HbA1c was defined as informative when the signal-to-noise ratio exceeded 1. RESULTS: Among 96,456 healthy adults, 46,284 (48.0%) were male; age (range) and mean HbA1c (SD) were 48 (30-74) years old and 5.4 (0.4)%, respectively. As risk increased among those 30-44 years old, HbA1c screening intervals for detecting Type 2 DM consistently decreased: from 10.5 (BMI <18.5) to 2.4 (BMI > 30) years, and from 8.0 (Framingham Risk Score <10%) to 2.0 (Framingham Risk Score ≥20%) years. This trend was consistent in other age and risk groups as well; among obese 30-44 year olds, we found substantially shorter intervals compared to other groups. CONCLUSION: HbA1c screening intervals for identification of DM vary substantially by risk factors. Risk stratification should be applied when deciding an optimal HbA1c screening interval in the general population to minimize overdiagnosis and overtreatment.

Having a Mentor or a Doctoral Degree Is Helpful for Mid-Career Physicians to Publish Papers in Peer-Reviewed Journals.

The evidence suggests that mentoring is one of useful teaching methods in academic medicine but it is not clear for which outcome mentoring is effective. In this study, the authors investigated the number of original research articles that the participants had published in peer-reviewed English-language journals (as a first or a corresponding author) within one year prior to investigation and what characteristics of the participants who published at least one paper would be like compared to those who did not. In March 2015, the authors recruit early- and mid-career Japanese physicians (238 men and 240 women; mean age 40.6 years old) in a web survey. In total, 23.9% of physicians had published at least one original research article as a first author, 10.0% had published as a corresponding author, and 23.4% had a research mentor. A multivariate logistic regression model adjusting for variables selected at p < 0.15 in univariable models showed that even after adjusting for their motivation levels for clinical research, physicians with a research mentor [odds ratio (OR) 6.68; 95% confidence interval (CI), 3.74-11.93], physicians who obtained DMSc, roughly equivalent to PhD in the West (OR, 2.17; 95% CI, 1.26-3.72), and physicians who worked at teaching hospitals (OR 6.39; 95% CI, 2.54-16.04) were more likely to publish an original paper in a peer-reviewed journal. Having a research mentor or DMSc is associated with an experience of successfully publishing original papers in peer-reviewed journals for young and mid-career physician-researchers.

Safety and efficacy of upfront graded administration of trimethoprim-sulfamethoxazole in systemic lupus erythematosus: A retrospective cohort study.

OBJECTIVES: Trimethoprim-sulfamethoxazole (TMP/SMX) is effective as prophylaxis against many infections in immunocompromised patients. However, it is not commonly prescribed for patients with systemic lupus erythematous (SLE) due to the risk of adverse reactions (ADRs). An upfront graded administration protocol for TMP/SMX was adopted, and its safety and efficacy were assessed. METHODS: Data from 59 patients with SLE patients who received prophylactic TMP/SMX were retrospectively analyzed. The incidence and risk factors for ADRs in patients who received TMP/SMX before and after the introduction of graded administration were assessed. RESULTS: The incidence of ADRs was 41.9% in the non-graded administration group, vs. 10.7% in the graded administration group (p = 0.009). The rate of high fever, liver function test (LFT) abnormality, shortness of breath, and hospitalization were reduced in upfront graded administration group. In addition, a higher rate of anti-Ro/SS-A positivity was found in patients experienced ADRs (46.2% in reactors vs. 5.6% in non-reactors; p = 0.012) in the non-graded administration group. CONCLUSIONS: Upfront graded administration of TMP/SMX reduces the incidence and severity of ADRs in SLE patients. The high incidence of TMP/SMX ADRs in SLE patients was also confirmed, especially when anti-Ro/SS-A antibody is present.

Association of weight gain since age 20 with non-alcoholic fatty liver disease in normal weight individuals.

BACKGROUND AND AIMS: Interventions for lifestyle diseases including non-alcoholic fatty liver disease (NAFLD) have focused on overweight and obese populations. The impact of adult weight gain on NAFLD development among normal weight individuals remains unclear. METHODS: In this cross-sectional study, we collected data from participants presenting to a health check-up program. Ultrasound-diagnosed NAFLD prevalence was examined over 1-kg increments of weight change since age 20. Relative risks were calculated in men and women stratified by current weight (normal, overweight, and obese). Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) adjusting for potential confounders. RESULTS: Among 21 496 participants, 3498 cases of NAFLD (16.3%) were observed. Prevalence of NAFLD increased with weight gain since age 20; among the 10.1-11.0 kg weight gain group, 41.6% of men and 24.8% of women had NAFLD. Multivariate analysis by quartiles showed that weight change was significantly associated with NAFLD risk in men and women. Risk of NAFLD associated with weight change (10-kg increments) was significantly higher in normal weight individuals (men: OR 7.53, 95% CI: 4.99-11.36, women: OR 12.20, 95% CI: 7.45-19.98) than overweight (men: OR 1.61, 95% CI: 0.91-2.85, women: OR 2.90, 95% CI: 0.99-8.54) and obese (men: OR 4.0, 95% CI: 2.97-5.39, women: OR 2.68, 95% CI: 2.00-3.60). CONCLUSIONS: NAFLD is robustly associated with weight change since age 20. This effect appears particularly strong in individuals at normal weight, suggesting an important role for early and longitudinal weight monitoring, even among healthy individuals at normal weight.

Image-enhanced, chromo, and cap-assisted colonoscopy for improving adenoma/neoplasia detection rate: a systematic review and meta-analysis.

OBJECTIVE: The effectiveness of narrow band imaging (NBI), chromoendoscopy (CE), and cap-assisted colonoscopy (CAC) on adenoma detection rate (ADR) has been investigated in previous meta-analyses; however, there have been no meta-analyses of autofluorescence imaging (AFI) or flexible spectral imaging color enhancement (FICE) or i-scan. The aim of this study was to determine whether AFI and FICE/i-scan was more effective than standard/high-definition white light endoscopy to improve ADR and to update previous meta-analyses of NBI, CE, and CAC. DESIGN: A systematic review and meta-analysis was conducted. Four investigators selected appropriate randomized controlled trials (RCT) using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guideline. All RCTs in which colonoscopy were performed with AFI, FICE, i-scan, NBI, CE, and CAC were included. The risk ratios (RRs) calculated from adenoma/neoplasia detection rate were used as the main outcome measurement. RESULTS: A total of 42 studies were included in the analysis. Pooled estimates of RR (95%confidence interval [CI]) using AFI, FICE/i-scan, NBI, CE, and CAC were 1.04 (95% CI: 0.87-1.24) (I² = 0%) (fixed effects model [FEM]); 1.09 (95% CI: 0.97-1.23) (I² = 5%) (FEM); 1.03 (95% CI: 0.96-1.11) (I² = 0%) (FEM); 1.36 (95% CI: 1.23-1.51) (I² = 16%) (FEM); and 1.03 (95% CI: 0.93-1.14) (I² = 48%) (random effects model [REM]), respectively. The pooled estimate of RR (95%CI) using indigo carmine in non-ulcerative colitis (UC) patients and methylene blue in UC patients was 1.33 (95% CI: 1.20-1.48) (I² = 14%) (FEM) and 2.39 (95% CI: 1.18-4.84) (I² = 0%) (FEM), respectively. CONCLUSION: In contrast to AFI, FICE/i-scan, NBI, and CAC, only CE improves ADR. CE with methylene blue, though not NBI, is effective for surveillance of neoplasia in chronic UC patients.
