RESUMO
BACKGROUND: Workplace cancer screening programs are determined as part of an employee's benefits package and health checkups are perceived positively. However, the current status of workplace cancer screening programs in Japan is unavailable. This study aimed to assess the adherence to national guidelines for colorectal, breast, and cervical cancer screenings in the workplace among Japanese enterprises and identify factors associated with excessive or inadequate screenings. METHODS: A cross-sectional study design was employed. Data were obtained from a survey conducted by the "Corporate Action to Promote Cancer Control" between November and December 2022 among registered partner enterprises in Japan. The survey included questions on background characteristics, cancer screening practices, and intervention approaches. The analysis included 432 enterprises that provided complete responses regarding colorectal, breast, and cervical cancer screenings. RESULTS: The guideline-adherence rates for colorectal, breast, and cervical cancer screenings in the workplace were 12.7%, 3.0%, and 8.8%, respectively. Enterprises had lower adherence to screening guidelines than local governments. Colorectal (70.8%) and breast (67.1%) cancer screenings were predominantly categorized as "overscreening" and cervical (60.6%) cancer screening, as "underscreening." Factors such as enterprise scale, health insurance associations, and the number of interventional approaches were significantly associated with increased "overscreening" (101-1000: ß = 0.13, p = 0.01; ≥ 1000: ß = 0.17, p < 0.01; health insurance association: ß = 0.23, p < 0.01; and approaches: ß = 0.42, p < 0.01) and reduced "underscreening" (101-1000: ß = -0.13, p = 0.01; ≥ 1000: ß = -0.17, p < 0.01; health insurance association: ß = -0.18, p < 0.01; and approaches: ß = -0.48, p < 0.01). CONCLUSION: Adherence to national guidelines for colorectal, breast, and cervical cancer screenings in the workplace was suboptimal among Japanese enterprises. Therefore, appropriate cancer screening measures and interventions to ensure guideline adherence and optimization of screening benefits while minimizing potential harms should be expeditiously implemented.

OBJECTIVES: In Japan, the risk of developing cancer among workers employed in workplaces where chemical substances are handled is unclear. This study aimed to assess the association between cancer risk and employment in workplaces handling hazardous chemicals. METHODS: The Inpatient Clinico-Occupational Survey of the Rosai Hospital Group data of 120 278 male patients with incident cancer and 217 605 hospital controls matched for 5-year age group, hospital (34 hospitals) and year of admission (2005-2019) were analysed. Cancer risk in relation to lifetime employment in workplaces using regulated chemicals was assessed while controlling for age, region and year of diagnosis, smoking, alcohol consumption and occupation. Further analysis stratified by smoking history was performed to examine interaction effects. RESULTS: In the longest group of employment in tertiles, ORs were increased for all cancers (OR=1.13; 95% CI: 1.07 to 1.19) and lung (OR=1.82; 95% CI: 1.56 to 2.13), oesophageal (OR=1.73; 95% CI: 1.18 to 2.55), pancreatic (OR=2.03; 95% CI: 1.40 to 2.94) and bladder (OR=1.40; 95% CI: 1.12 to 1.74) cancers. Employment of 1+ years was associated with risk for lung cancer; 11+ years for pancreatic and bladder cancers; and 21+ years for all cancers and oesophageal cancer. These positive relationships were particularly obvious among patients with a history of smoking; however, no significant interaction between smoking and length of employment was observed. CONCLUSIONS: There is a high risk of cancer among workers, especially smokers, employed in workplaces handling regulated chemicals in Japan. Thus, future measures for chemical management in workplaces are needed to prevent avoidable cancers.

BACKGROUND: A person's occupation may increase his/her risk for developing inflammatory bowel disease (IBD). This study investigated the association between risk for later-onset of IBD and both specific occupations and occupational physical activity (OPA) levels. MATERIALS AND METHODS: A multicenter hospital-based matched case-control study was conducted using the Inpatient Clinico-Occupational Survey database. Cases were patients with Crohn's disease (CD) and ulcerative colitis (UC) patients admitted for the first time between 2005 and 2015. Four controls matched by age, sex, admission year and hospital were selected for each case. Cases and controls were grouped into the longest-held occupations as classified by the Japanese Standard Occupational Classification and OPA levels. We conducted conditional logistic regressions to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for IBD, CD and UC adjusted for alcohol consumption and smoking status. RESULTS: There were 564 cases (172 CD, 392 UC) and 2086 controls. The risk for UC was higher among sales workers and carrying, cleaning and packing workers (ORs 2.62 [95%CIs 1.18-5.82], 2.52 [1.04-6.09]). There was no association between occupation type and CD risk. Higher OPA level decreased CD risk (OR 0.51 [95%CIs 0.26-1.00]) and increased UC risk (OR 1.53 [95%CIs 1.02-2.30]). CONCLUSIONS: Our study revealed that the risk for later-onset of UC, but not CD, was associated with longest-held 'service' and 'manufacture' work. The risk by OPA levels was inversely associated between CD and UC. Further studies are needed by follow-up method for long-term effects of physical activity.

We aimed to examine whether the number of types of hazardous operations at work experienced through a lifetime is associated with cancer incidence, and additionally examined the combined effects with lifestyle-related factors. Using a nationwide, multicenter, hospital inpatient dataset (2005-2015), we conducted a matched case-control study with 1 149 296 study subjects. We classified the participants into those with none, 1, or 2 or more types of hazardous operation experience, based on information of special medical examinations taken, mandatory in Japan for workers engaged in hazardous operations. Using those with no experience as the reference group, we estimated the odds ratios for cancer incidence (all sites, lung, stomach, colon and rectum, liver, pancreas, bile duct, and bladder) by conditional logistic regression with multiple imputations. We also examined the effects of the combination with hazardous operations and lifestyle-related factors. We observed increased risks for cancer of all sites, and lung, pancreas, and bladder cancer associated with the experience of hazardous operations. Multivariable-adjusted ORs (95% CIs) of cancer incidence of all sites were 1 (reference), 1.16 (1.12, 1.21), and 1.17 (1.08, 1.27) for none, 1, and 2 or more types of hazardous operation experience, respectively (P for trend <.001). Potential combined associations of hazardous operations with smoking were observed for lung, pancreas, and bladder cancer, and with diabetes for pancreas cancer. Engaging in hazardous operations at work and in combination with lifestyle-related factors may increase the risk of cancer. We highlight the potential for those engaged in hazardous work to avoid preventable cancers.

BACKGROUND: This retrospective cohort study primarily aimed to investigate the possible association of computer use with visual field abnormalities (VFA) among Japanese workers. METHODS: The study included 2,377 workers (mean age 45.7 [standard deviation, 8.3] years; 2,229 men and 148 women) who initially exhibited no VFA during frequency doubling technology perimetry (FDT) testing. Subjects then underwent annual follow-up FDT testing for 7 years, and VFA were determined using a FDT-test protocol (FDT-VFA). Subjects with FDT-VFA were examined by ophthalmologists. Baseline data about the mean duration of computer use during a 5-year period and refractive errors were obtained via self-administered questionnaire and evaluations for refractive errors (use of eyeglasses or contact lenses), respectively. RESULTS: A Cox proportional hazard analysis demonstrated that heavy computer users (>8 hr/day) had a significantly increased risk of FDT-VFA (hazard ratio [HR] 2.85; 95% confidence interval [CI], 1.26-6.48) relative to light users (<4 hr/day), and this association was strengthened among subjects with refractive errors (HR 4.48; 95% CI, 1.87-10.74). The computer usage history also significantly correlated with FDT-VFA among subject with refractive errors (P < 0.05), and 73.1% of subjects with FDT-VFA and refractive errors were diagnosed with glaucoma or ocular hypertension. CONCLUSIONS: The incidence of FDT-VFA appears to be increased among Japanese workers who are heavy computer users, particularly if they have refractive errors. Further investigations of epidemiology and causality are warranted.

Neonicotinoids, such as acetamiprid (ACE), a pesticide used worldwide, are believed to be safe for human use. These molecules are structurally similar to nicotine, act as nicotinic acetylcholine receptor (nAChR) agonists, and were shown to be associated with neuromuscular and reproductive disorders, but these experiments were primarily performed in mature animals. In this study, the effects of ACE on the testes of immature mice were examined. The exposure of 3-week-old mice to ACE-containing water for 180 days led to a decrease in body weight and mildly affected spermatogenesis. Additionally, the expression of testosterone-metabolism genes, nAChR subunit genes, and proliferation-associated genes decreased in the testes of ACE-treated mice. Our results show that immature rodents may be less sensitive to ACE than mature ones, that mice may be more likely to accumulate ACE than rats, and that the development of disorders may be affected by the accumulation of ACE in the testes.

Embryo transfer (ET) to recipient female animals is a useful technique in biological and experimental animal studies. While cryopreservation of two-cell stage rat embryos and ET to recipient rats are currently well-defined, it is unknown whether these artificial reproductive techniques and maternal factors affect offspring phenotype, particularly higher brain functions. Therefore, we assessed the effects of cryopreservation, ET, and maternal care on learning behaviour of the offspring, using Tokai high avoider (THA) rats that have a high learning ability phenotype. We found that the high learning ability of THA rat offspring was not replicated following ET to surrogate Wistar rats with a low-avoidance phenotype. Additionally, the characteristic phenotype of offspring obtained through mating of ET-derived rats was similar to that of THA rats. A postnatal cross-fostering investigation with the offspring of Wistar and THA rats showed that maternal behaviour, including postnatal care and lactation traits, did not differ between the dams of low-avoidance Wistar rats and THA rats; therefore, learning behaviour was retained in both Wistar and THA rat offspring. We conclude that the offspring phenotype, although unchanged, has an imperceptible effect on the learning ability of ET-derived THA rats through the intrauterine environment of the recipient.

BACKGROUND/AIM: What naturally happens to patients after they undergo conservative and endoscopic treatment of colonic diverticular bleeding (CDB) is largely unknown. We retrospectively track the long-term outcome of the recurrence of CDB between patients with endoscopic and conservative treatment. METHODS: The group was divided into 2 groups: patients treated with injection and/or clipping (endoscopic group) and patients in whom such treatment could not be performed (conservative group). CDB recurrence was assessed via a questionnaire, and recurrence rates were investigated between groups using the Kaplan-Meier's method. The Cox proportional hazards model was performed to identify potential risk factors for recurrence. RESULTS: Eighty-eight patients answered the questionnaires. The median (interquartile range) follow-up period was 42.7 (61.8) months. Twenty-four (38.7%) of 62 conservatively treated patients and 16 (61.5%) of 26 endoscopically treated patients experienced recurrence of CDB during the follow-up period. Kaplan-Meier's analysis showed that the rate of recurrence was significantly higher (p < 0.05) in cases with endoscopic treatment than in those with conservative treatment (mean time to recurrence = 55.3 months (95% CI 30.8-79.9) vs. 99.9 months (95%CI 80.7-119.1)). The Cox proportional hazards model did not identify any significant variables. CONCLUSION: We should carefully follow-up patients to check for the recurrence of CDB, even when it could be successfully treated endoscopically. Can endoscopic treatment of CDB prevent CDB recurrence? Also, what happens to the patient's well-being after they undergo conservative and endoscopic treatment (cases diagnosed by Jensen's criteria) is largely unknown. We examined a population of patients undergoing conservative or endoscopic treatment to clarify the clinical course, particularly with regard to CDB recurrence.

BACKGROUND: Approximately 20% to 40% of patients with gastroesophageal reflux disease (GERD) are refractory to standard-dose proton-pump inhibitor (PPI) treatment. OBJECTIVE: We compared the efficacy and quality-of-life effects of 20 mg once daily (QD) versus 10 mg twice daily (BID) rabeprazole (RPZ) in patients with refractory GERD-related symptoms and sleep disturbances. METHODS: This multicenter, prospective, randomized, open-label study included patients in whom PPI treatment >4 weeks was ineffective. According to the Global Overall Symptom (GOS) scale, PPI-refractory GERD was defined as ≥1 category with >3 points among 10 specific upper gastrointestinal symptoms. Seventy-eight patients were randomly assigned to 20 mg QD and 10 mg BID RPZ groups for 8 weeks. Efficacy was evaluated using self-reported questionnaires, including the GOS scale and Pittsburg Sleep Quality Index (PSQI), whereas quality of life was assessed using the Short-Form 8 Health Survey (SF-8), at 4 and 8 weeks. Patients showing improvement at 8 weeks received follow-up every 4 to 8 weeks. RESULTS: GOS scale scores were significantly improved at 8 weeks in both groups, with no significant intergroup differences. Although SF-8 scores showed an increasing trend over 8 weeks in both groups, the physical component summaries in the 10 mg BID group significantly improved. The mental component summaries clearly improved in the 10 mg BID group. Of the 74 cases (4 missing), 51 (68.9%) had PSQI scores ≥5.5. PSQI scores remained unchanged during follow-up in both groups. The recurrence rate was not significantly different (46.1% vs 47.1% in the 20 mg QD and 10 mg BID groups, respectively) during the follow-up period at median (interquartile range) 24.0 (30.5) months. CONCLUSIONS: In patients with refractory GERD, there was no significant difference in GOS scale score, PSQI, or recurrence rate between the groups. With regard to subscores of the SF-8, the 10 mg BID group might be potentially effective.
RESUMO
Although Annexin A8 (ANXA8), a member of a superfamily of calcium and phospholipid binding proteins, is physiologically expressed in a tissue-specific manner, recent microarray studies reported that ANXA8 was also ectopically expressed in pancreatic cancers. We investigated the molecular mechanism of expression of ANXA8 in cancer cells and its functional role in pancreatic cancer cells. ANXA8 was diversely expressed in human cancer cell lines. Expression was enhanced by treatment with 5-aza-dC and butyrate, and correlated with methylation status at CpG in the promoter-exon 1 region. Inhibition of ANXA8 using siRNA in BxPC-3 cells which express ANXA8 at a high level elevated caspase-3 and -7 activities. In in vitro invasion assay, inhibition of ANXA8 using siRNA in BxPC-3 reduced the numbers of migrating cells, and down-regulated HIF-1α mRNA transcription. Overexpression of ANXA8 increased the number of viable cells and BrdU incorporation in PANC-1 cells, which express ANXA8 at a low level. Expression of ANXA8 was induced under conditions of nutrient deprivation, and overexpression of ANXA8 showed resistance against serum starvation in PANC-1 cells. In a promoter assay, co-transfection with the expression vector of ANXA8 and the vector of a reporter gene containing the promoter of HIF-1α enhanced HIF-1α promoter activity. In contrast, this effect of ANXA8 was inhibited by administration of BAPTA-AM, an intracellular Ca²âº chelator. These results suggest that ectopic ANXA8 expression in cancer cells might involve an epigenetic mechanism. ANXA8 might play an important role in calcium fluctuation-mediated HIF-1α transcriptional activation and cell viability.

OBJECTIVE: The molecular mechanisms underlying the carcinogenic activity of not-directly mutagenic (Ames mutagenicity test-negative) carcinogens are not fully understood. Given recent findings that ectopic expression of activation-induced cytidine deaminase (AID) in somatic cells plays a critical role in carcinogenesis, we investigated whether several of the established not-directly mutagenic carcinogens induce AID expression. METHODS: We prepared cells with stable expression of luciferase reporter gene containing the promoter of AID. We then used this system to examine the AID promoter activity of the non-genotoxic carcinogen: butyl benzyl phthalate, bisphenol A, di (2-ethylhexyl) phthalate, cadmium chloride (Cd), and butylated hydroxyanisole. RESULTS: Results showed that Cd increased the promoter activity of AID and actually induced AID gene expression. CONCLUSION: A not-directly mutagenic carcinogen, cadmium, has the potential to induce the AID gene, suggesting that this might represent a novel molecular mechanism of carcinogenesis of cadmium.

PRCIS: The analysis of intraocular pressure (IOP) by day of the week using the mega database showed a periodic weekly pattern with the highest value on Monday. PURPOSE: To evaluate IOP by the day of the week. PATIENTS AND METHODS: Annual health checkup examinees between April 2014 and March 2015 were cross-sectionally evaluated. As a result, 655,818 participants [51.5±10.5 (range: 20-96) years, 40.1% women] from 103 medical centers were included. IOP was measured using a noncontact tonometer. The mean IOPs of each day of the week were compared using multiple comparison test and multiple linear regression analysis. Wednesday was set as the reference. Moreover, weekly IOP variations stratified by sex and age were also evaluated. RESULTS: Mean IOPs from Monday to Sunday were 13.19±2.97, 13.06±2.92, 13.05±2.91, 13.05±2.92, 13.12±2.94, 13.10±2.96, and 13.16±2.78 mm Hg. IOP was significantly higher on Monday, Friday, and Saturday than those on Wednesday ( P <0.001, <0.001, 0.002). After adjusting for factors affecting IOP, the IOPs on Monday and Saturday were higher than those on Wednesday [ß=0.097 (95% CI: 0.074-0.121), P <0.001; ß=0.032 (95% CI: 0.005-0.059), P =0.019]. Men had significantly higher IOPs on Monday and Saturday than on Wednesday [ß=0.142 (95% CI: 0.110-0.173), P <0.001; ß=0.053 (95% CI: 0.017-0.089), P =0.004], whereas women did not have a significant trend. Participants aged below 65 years had higher IOPs on Monday ( P <0.001 in under 60 years; P =0.003 in 60-64 years), while those aged 65 years or older did not ( P =0.856). CONCLUSION: IOP values may have a periodic weekly pattern. The high IOP on Monday was more pronounced in men aged less than 65 years.

PURPOSE: To assess the effects of intraocular lens (IOL) decentration and tilt, as well as age, on postoperative visual function (corrected distance visual acuity [CDVA] and contrast sensitivity) by comparing an extended depth-of-focus IOL using higher order aspheric optics against a monofocal IOL from the same platform. METHODS: This retrospective observational study targeted patients without other eye diseases who underwent surgery to implant the Tecnis Eyhance OptiBlue or the monofocal IOL Tecnis OptiBlue 1-Piece (J&J Vision) during cataract surgery from November 2021 to December 2022. The effects of age, axial length, IOL decentration, tilt, and corneal higher order aberrations (HOAs) on the postoperative 5 m CDVA and area under log contrast sensitivity function (AULCSF) under photopic and scotopic conditions were evaluated within 3 months of surgery. RESULTS: No significant difference was found in postoperative CDVA between the Tecnis Eyhance OptiBlue group (n = 61 eyes) and the Tecnis OptiBlue 1-Piece group (n = 35 eyes), but AULCSF was significantly better in the Tecnis Eyhance OptiBlue group for photopic (1.58 ± 0.13 vs 1.46 ± 0.18; P = .002) and scotopic (1.71 ± 0.11 vs 1.59 ± 0.19; P = .002) eyes. Multivariate analysis showed a negative correlation between AULCSF and IOL decentration and age in the Tecnis Eyhance OptiBlue group (P < .01), with no significant correlation with tilt, axial length, and corneal HOAs. CONCLUSIONS: The Tecnis Eyhance OptiBlue yielded significantly better contrast sensitivity under photopic and scotopic conditions than the Tecnis OptiBlue 1-Piece. However, it is important to consider the effects of IOL decentration and age when evaluating the contrast sensitivity of the Tecnis Eyhance OptiBlue. [J Refract Surg. 2024;40(7):e499-e505.].

PURPOSE: This study sought to identify the most effective testing program for detecting visual-field defects in mild-stage glaucoma with central visual-field defects. DESIGN: A multicenter, retrospective diagnostic testing evaluation. PARTICIPANTS: The study involved 93 eyes (83 patients) with mild-stage glaucoma (median mean deviation [interquartile range]: -1.79 [2.16] dB) with central visual-field defects and 69 eyes (63 patients; median mean deviation, -1.38 [2.31] dB) with mild-stage glaucoma without central visual-field defects, from Jikei University School of Medicine and Tajimi Iwase Eye Clinic. METHODS: Patients underwent 10-2 Swedish Interactive Thresholding Algorithm (SITA) Standard, 24-2 SITA Standard, and 24-2C SITA Faster tests. Central visual-field defects were defined using 10-2 SITA Standard and optical coherence tomography (OCT). A detection power of 4 points in the 24-2 that coincided with 10-2 (Center4), 12 points that lie within 10° (24-2-12), and 22 points that lie within 10° of 24-2C (24-2C-22) were analyzed using receiver operating characteristic (ROC) curves based on logistic regression analysis, using total deviation (TD) and pattern deviation (PD) probability plots. MAIN OUTCOME MEASURES: Area under the receiver operating characteristic curve (AUC) of the Center4, 24-2-12, and 24-2C-22 tests. RESULTS: In the upper-central visual field, AUCs of the TD plot were 0.50 (0.40-0.58) for the Center4, 0.75 (0.67-0.83) for 24-2-12, and 0.85 (0.78-0.91) for 24-2C-22, with 24-2C-22 AUC significantly exceeding 24-2-12 AUC. For the PD plot, AUCs were 0.53 (0.44-0.63), 0.81 (0.74-0.89), and 0.84 (0.77-0.90), respectively. In the lower-central visual field, using a total plot, AUCs were 0.27 (0.18-0.36), 0.57 (0.47-0.69), and 0.57 (0.46-0.68) for the Center4, 24-2-12, and 24-2C-22, respectively. Using the PD plot in the upper field, AUCs were 0.27 (0.19-0.36), 0.64 (0.53-0.75), and 0.81 (0.72-0.90), respectively, with the AUC of the 24-2C-22 significantly exceeding that of 24-2-12. The 24-2C test was significantly faster than both the 24-2 and 10-2 tests, reducing testing duration by 46% and 52%, respectively. CONCLUSIONS: The 24-2C SITA Faster test is highly effective and efficient for detecting mild-stage glaucoma with central visual-field defects. This, and its reduced duration, makes it a valuable tool in clinical settings.
RESUMO
Purpose: We aimed to preliminarily compare the glaucoma detection accuracy of a head-mounted binocular visual perimeter "imo" screening program (ISP) with that of frequency doubling technology (FDT). Methods: This multicenter, diagnostic accuracy study based on prospectively collected data included 76 non-glaucoma (including pre-perimetric glaucoma) eyes and 92 glaucomatous eyes from patients visiting two hospitals. Patients underwent ISP and FDT (C-20-1 screening program) on the same day. Diagnostic efficacy was evaluated using receiver operating characteristic curves and areas under the curve (AUCs). In addition, we compared the ISP and FDT testing times. Results: AUC values for ISP versus FDT were as follows: (1) mild-stage glaucoma (mean deviation [MD] > -6 dB), 0.82 (95% confidence interval [CI], 0.75-0.88) versus 0.76 (95% CI, 0.68-0.83); moderate-stage glaucoma (-6 dB ≥ MD ≥ -12 dB), 0.98 (95% CI, 0.95-1.00) versus 0.96 (95% CI, 0.93-1.00); and advanced-stage glaucoma (-12 dB > MD), 1.00 (95% CI, 1.00-1.00) versus 0.99 (95% CI, 0.98-1.00). In addition, mild-stage glaucoma was classified into two stages (MD > -3 D) and (-3 D ≥ MD > -6 D). AUC values were 0.81 (95% CI, 0.73-0.88) versus 0.76 (95% CI, 0.68-0.84) for MD > -3 D and 0.86 (95% CI, 0.77-0.94) versus 0.73 (95% CI, 0.61-0.86) for -3 D ≥ MD > -6 D. The testing time for the ISP was significantly shorter than that of FDT for all glaucoma stages (P < 0.001). Conclusions: The ISP demonstrates non-inferiority in detecting glaucoma and has a shorter testing time compared with FDT. These findings provide evidence for applied further studies on large-scale population-based glaucoma screening. Translational Relevance: Our study provides a non-inferior and quicker glaucoma screening than existing tools.

Purpose: To examine the variability in glaucoma screening using fundus images among physicians, including non-ophthalmologists. Patients and Methods: Sixty-nine eyes from 69 patients, including 25 eyes with glaucoma, were included from the Jikei University Hospital from July 2019 to December 2022. Fundus images were captured using TRC-NW8 (Topcon Corporation, Tokyo, Japan), and were interpreted by 10 non-ophthalmologists, 10 non-specialist ophthalmologists, and 9 specialists for diagnostic accuracy. We analyzed differences in diagnostic accuracy among the three groups. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and Kappa coefficient were compared, using the Kruskal-Wallis test followed by a post hoc Dunn's test. Results: The sensitivity and specificity were 0.22 and 0.92 for non-ophthalmologists, 0.49 and 0.83 for non-specialist ophthalmologists, and 0.68 and 0.87 for specialists, respectively. Both specialists and non-specialist ophthalmologists showed significantly higher sensitivity than non-ophthalmologists (Dunn's test, P<0.001 and P=0.031). There was no significant difference in specificity among the three groups (Kruskal-Wallis test, P=0.086). The PPV did not differ significantly between the groups (Kruskal-Wallis test, P=0.108), while the NPV was significantly higher in specialists compared to non-ophthalmologists (Dunn's test, P<0.001). Specialists also had a significantly higher Kappa coefficient than non-ophthalmologists and non-specialist ophthalmologists (Dunn's test, P<0.001 and P=0.024). Conclusion: Diagnostic accuracy varied significantly based on the physician's background.
RESUMO
We conducted a retrospective study of the efficacy of a polyethylene glycol purge before colonoscopic examination in 110 patients with colonic diverticular bleeding. The patients' data were assessed for the timing of colonoscopy and the methods used to stop bleeding. The rate at which bleeding diverticula were identified was markedly higher when a purge was used than when it was not (28.2% vs. 12.0%, p=0.11). In addition, the identification rate was significantly higher when colonoscopic examination was performed within 18 hours of the final hematochezia than when it was performed after 18 hours (40.5% vs. 10.5%, p<0.01). These findings suggest that patients with diverticular bleeding should undergo colonoscopy following an orally administered colonic purge, providing their condition permits. Furthermore, colonoscopy should be performed within 18 hours of the final hematochezia in order to improve identification of the bleeding diverticulum.

OBJECTIVES: Most cancer control measures in the workplace have limited supporting evidence. This study aimed to identify highly effective cancer control measures, based on a survey by the Corporate Action to Promote Cancer Control. METHODS: The firms and organizations that responded to the web survey were included. The questionnaire comprised five cancer (stomach, lung, colorectal, breast, and cervical) screening rates and their countermeasures to promote cancer control. We conducted a non-hierarchical cluster analysis according to the degree of the measures and compared the screening rates among each group using an analysis of variance. Then, we performed two multiple regression analyses with the mean screening rates for stomach/lung/colorectal cancer and breast/cervical cancer as dependent variables, the implementation of each countermeasure as an independent variable, and the size and industry as control variables. RESULTS: We obtained responses from 704 firms and organizations. The three groups classified by cluster analysis were defined as active, moderate, and negative. For all cancer screenings, the main effects were significant, and multiple comparisons revealed that the difference between the active and negative groups (ts > 3.30, ps < .01, Hedges' ds > 0.73) and the moderate and negative groups (ts > 3.70, ps < .01, Hedges' ds > 0.88) were significant. For the four cancers other than lung, the difference between the active and moderate groups was not significant (ts < 0.21, ps < .84, Hedges' ds < 0.02), and for lung, the difference was significant, but the effect size was small. The multiple regression analyses revealed that "distribution of colorectal cancer test kits to all subjects" (ß = 0.14) was significant for stomach, lung, and colorectal cancer, while "financial supports for cancer screening" (ß = 0.24), "screening as part of employment" (ß = 0.18), and "careful screening of female subjects" (ß = 0.17) were significant for breast and cervical cancer, respectively. CONCLUSIONS: We identified effective countermeasures for cancer control in the workplace, and these measures will help increase cancer screening rates.

This cross-sectional study aimed to investigate the promoting and inhibitory factors of diabetic retinopathy (DR) according to diabetes mellitus (DM) stage using standardized evaluation of fundus images by artificial intelligence (AI). A total of 30,167 participants underwent blood and fundus examinations at a health screening facility in Japan (2015-2016). Fundus photographs were screened by the AI software, RetCAD and DR scores (DRSs) were quantified. The presence of DR was determined by setting two cut-off values prioritizing sensitivity or specificity. DM was defined as four stages (no DM: DM0; advanced DM: DM3) based on treatment history and hemoglobin A1c (HbA1c) levels. Associated factors of DR were identified using logistic regression analysis. For cutoff values, multivariate analysis revealed age, sex, systolic blood pressure (SBP), smoking, urinary protein, and HbA1c level as positively associated with the risk of DR among all DM stages. In addition to glycemic control, SBP and Fibrosis-4 index might act as promoting factors for DR at all or an earlier DM stage. T-Bil, cholinesterase, and T-cho level might be protective factors at an advanced DM stage.

BACKGROUND: Fib4 index (Fib4) is clinically used as a noninvasive marker of liver fibrosis. In this study, we aimed to preliminarily investigate whether Fib4 can be used to detect individuals who need assessment for alcoholic liver disease (ALD) in the general population by clarifying the detailed association of Fib4 with alcohol consumption and gamma-glutamyl transferase (GGT) among male workers. METHODS: We analyzed data sets on the comprehensive medical examinations of male workers as cross-sectional and retrospectively longitudinal studies. We enrolled 10 782 males (mean age: 52.2 ± 10.2 years) in FY2019 and 7845 males (mean follow-up: 12.6 ± 6.7 years) who could be consecutively followed up for 20 years from FY2000 to FY2019. Data were evaluated using logistic regression and COX proportional analysis. RESULTS: In the cross-sectional setting, the rate of Fib4 ≥ 2.67 in heavy drinkers (≥ 40 g of ethanol/day) was increased dose dependently in those over 65 years old, and that of body mass index ≥ 30 kg/m2 was increased in those over 60 years old, but not in those with fatty liver. The odds ratio (OR) (95% confidence interval [CI]) for heavy drinking was 4.30 (95% CI = 1.90-9.72), and GGT ≥ 200 IU/L was considerably high (OR = 29.05 [95% CI = 17.03-49.56]). In the longitudinal setting, heavy drinkers and those with GGT ≥ 200 IU/L at 10 years after the baseline showed an increased risk for Fib4 ≥ 2.67 (hazard ratio = 2.17 [95% CI = 1.58-2.98] and 7.65 [95% CI 5.26-11.12], respectively). CONCLUSIONS: The development of Fib4 ≥ 2.67 after 10 years was associated with heavy alcohol drinking and GGT level ≥ 200 IU/L. Therefore, Fib4 combined with GGT could indicate high risk of ALD. However, clinical examinations and course observations are essentially needed.
