Comparison of BMI changes in Japanese adults receiving face-to-face versus online counseling for specific health guidance: a non-inferiority prospective observational study. J Occup Health 2024:uiae026. [PMID: 38729214 DOI: 10.1093/joccuh/uiae026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2023] [Revised: 04/25/2024] [Accepted: 05/08/2024] [Indexed: 05/12/2024] Open
Abstract
OBJECTIVES This study aimed to evaluate the non-inferiority of online counseling over face-to-face counseling for specific health guidance (SHG). METHODS This prospective observational study was conducted using specific health checkup (SHC) and SHG data of individuals with health insurance in Japan. We analyzed data from 1,431 participants who met the inclusion criteria, including those who underwent online or face-to-face counseling between April 1, 2020 and March 31, 2021, and received an SHC in the following year but no earlier than 90 days after their first counseling session. Assessed variables comprised demographics, counseling methods, and SHC results, including baseline questionnaire findings and body mass index (BMI) at follow-up. We performed inverse probability of treatment weighting (IPTW) using propensity scores, with changes in BMI as the objective variable and the counseling method as the explanatory variable. We set the non-inferiority margin to 0.175, based on a previous study. RESULTS The online and face-to-face counseling groups comprised 455 (31.8%) and 976 (68.2%) participants, respectively. The number of men and mean age were 214 (47.0%) and 49.9 years (standard deviation: 6.9 years), respectively, in the online counseling group and 491 (50.3%) and 51.1 years (7.6 years), respectively, in the face-to-face counseling group. IPTW using propensity scores revealed a regression coefficient (95% confidence interval) of -0.014 (-0.157, 0.129) for the online group compared to the face-to-face group (p=.847). The confidence interval was within the non-inferiority margin. CONCLUSIONS The effects of online counseling on BMI are likely non-inferior to those of face-to-face counseling.

Clinical significance of a basophil activation test for Japanese beekeepers naturally sensitized to honey bee venom. Asian Pac J Allergy Immunol 2024. [PMID: 38710645 DOI: 10.12932/ap-030124-1759] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 05/08/2024]
Abstract
BACKGROUND The basophil activation test (BAT) has high sensitivity and specificity for diagnosing Hymenoptera venom allergy and is useful for predicting the clinical sensitivity of bee venom-allergic patients after venom immunotherapy. Patients sensitized to Hymenoptera venom are at risk for systemic reactions (SRs) to subsequent stings. Therefore, a tool that can predict the occurrence of SRs and the severity of Hymenoptera stings is needed. OBJECTIVE We performed BATs on Japanese beekeepers naturally sensitized to honey bee venom (HBV) and analyzed the positive threshold concentration for the occurrence of SRs following honey bee stings (HBS). METHODS Sixty-one beekeepers were interviewed and blood samples were taken. Data including history of HBS and the occurrence and severity of SRs to HBS were recorded. Blood samples were exposed to HBV-specific IgE antibodies (sIgE) and BAT was performed. Participants with HBV-sIgE ≥ class 1 were considered sensitized to HBV. The positive threshold for BAT scored as 0.0001, 0.001, 0.01, 0.1, and 1 μg/ml was classified as classes 5, 4, 3, 2, and 1, respectively. Samples negative at 1 μg/ml were classified as class 0. RESULTS About 40% of beekeepers with a positive BAT threshold ≤ 0.1 μg/ml had SRs after HBS. The mean score of the BAT positivity threshold for beekeepers who developed SRs was significantly lower than that for beekeepers with no history of SRs (2.6 ± 0.8 vs 1.4 ± 1.1, P < 0.01). CONCLUSION Analysis of the positive threshold of BAT in Japanese beekeepers naturally sensitized to HBV may be a useful tool for predicting the occurrence of SRs.

Real-world effectiveness of erenumab in Japanese patients with migraine. Heliyon 2024; 10:e26568. [PMID: 38420497 PMCID: PMC10900787 DOI: 10.1016/j.heliyon.2024.e26568] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Revised: 01/18/2024] [Accepted: 02/15/2024] [Indexed: 03/02/2024] Open
Abstract
Background Real-world evidence of erenumab effectiveness in migraine patients in Asia with various comorbidities and multiple previous medication failures is still limited. Methods A 6-month single-center cohort study of 45 patients with episodic or chronic migraine (CM) treated with erenumab was conducted. In the cohort, 60.0% were switching from other calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs), and 66.7% had ≥4 prophylaxis failures. The change in monthly migraine days (MMDs) from baseline and percentages of responders after treatment were calculated. Weekly migraine days (WMDs) were obtained at baseline and at months 1, 2 and 3 and were compared between weeks 2 and 4. Results In total, 36%, 47%, and 63% of patients had a ≥30% response at 1, 3, and 6 months, respectively. The cumulative percentage of patients achieving a ≥30% response over 6 months was 85%. Early responders (average ≥ 30% response at 1-3 months) accounted for 37.8%, 55.6%, and 25.9% of the total, CGRP mAb-naïve, and CGRP mAb-switching groups, respectively. Late responders (average < 30% response at 1-3 months and average ≥ 30% response at 4-6 months) accounted for 46.4%, 37.5%, and 58.8% of nonearly responders in the total, CGRP mAb-naïve, and CGRP mAb-switching groups, respectively. Mild adverse reactions were observed in 5 patients (11.1%). Wearing-off, defined as an increase in the number of WMDs ≥2 between week 2 and week 4, was observed in 2.4-12.5% at months 1-3. Conclusion Erenumab was effective in migraine patients. At least 4-6 months may be preferable for efficacy evaluation in patients switching to erenumab from other CGRP mAbs.

Associations between the burdens of comorbid sleep problems, central sensitization, and headache-related disability in patients with migraine. Front Neurol 2024; 15:1373574. [PMID: 38601337 PMCID: PMC11006273 DOI: 10.3389/fneur.2024.1373574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 02/15/2024] [Indexed: 04/12/2024] Open
Abstract
Objective Sleep disturbances are common in migraine patients and affect quality of life. Central sensitization (CS) is likely to play a role in the increased severity and chronicity of migraine. We hypothesized that the number of comorbid sleep problems would affect headache-related disability through the effects of central sensitization (CS). Methods We performed a cross-sectional study including 215 consecutive patients with migraine. Insomnia was defined as a Pittsburgh Sleep Quality Index (PSQI) global score greater than 5. Probable REM sleep behavior disorder (pRBD) was defined as an RBD screening score of 5 or greater. Excessive daytime sleepiness (EDS) was defined as an Epworth Sleepiness Scale score of 10 or higher. Suspected sleep apnea (SA) was defined as patients with snoring or sleep apnea witnessed 3 or more nights a week. CS was assessed by the Central Sensitization Inventory (CSI). Results Restless legs syndrome, insomnia, EDS, SA and pRBD were observed in 25.6%, 71.6%, 34.4%, 10.2%, and 21.4%, respectively, of the patients. At least one sleep problem was present in 87.0% of the patients. According to the results of the multinomial logistic regression analysis with no sleep problems as a reference, after we corrected for adjustment factors, the Migraine Disability Assessment (MIDAS) score significantly increased when three or more comorbid sleep problems were present. According to our mediation analysis, an increased number of sleep problems had a direct effect on the MIDAS score after we adjusted for other variables, and the CSI score was indirectly involved in this association. Conclusion The present study showed an association between migraine-related disability and the burden of multiple sleep problems, which was partially mediated by CS.

Association between neuromuscular blocking agent use and outcomes among out-of-hospital cardiac arrest patients treated with extracorporeal cardiopulmonary resuscitation and target temperature management: A secondary analysis of the SAVE-J II study. Resusc Plus 2023; 16:100476. [PMID: 37779884 PMCID: PMC10540044 DOI: 10.1016/j.resplu.2023.100476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2023] [Revised: 09/04/2023] [Accepted: 09/11/2023] [Indexed: 10/03/2023] Open
Abstract
Background Neuromuscular blocking agents are used to control shivering in cardiac arrest patients treated with target temperature management. However, their effect on outcomes in patients treated with extracorporeal cardiopulmonary resuscitation is unclear. Methods This study was a secondary analysis of the SAVE-J II study, a retrospective multicenter study of 2175 out-of-hospital cardiac arrest patients treated with extracorporeal cardiopulmonary resuscitation in Japan. We classified patients into those who received neuromuscular blocking agents and those who did not and compared in-hospital mortality and incidence rates of favorable neurological outcome and in-hospital pneumonia between the groups using multivariable regression models and stabilized inverse probability weighting with propensity scores. Results Six hundred sixty patients from the SAVE-J II registry were analyzed. Neuromuscular blocking agents were used in 451 patients (68.3%). After adjusting for potential confounders, neuromuscular blocking agents use was not significantly associated with in-hospital mortality (aHR 0.88; 95% CI, 0.67-1.14), favorable neurological outcome (aOR 0.85; 95% CI, 0.60-1.11), or pneumonia (aOR 1.52; 95% CI, 0.85-2.71). The results for in-hospital mortality (aHR 0.89; 95% CI, 0.64-1.25), favorable neurological outcome (aOR 0.94; 95% CI, 0.59-1.48) and pneumonia (aOR 1.59; 95% CI, 0.74-3.41) were similar after weighting was performed. Conclusions Although data on the rationale for using neuromuscular blocking agents were unavailable, their use was not significantly associated with outcomes in out-of-hospital cardiac arrest patients treated with extracorporeal cardiopulmonary resuscitation and targeted temperature management. Neuromuscular blocking agents should be used based on individual clinical indications.

Abstract
The impact of the coronavirus disease 2019 (COVID-19) pandemic on pregnancy outcomes in Japan at the national level is unclear. This study aimed to assess the impact of the pandemic on pregnancy complications and delivery outcomes in Japan using nationwide population-based longitudinal data. Secondary data from the Japan Society of Obstetrics and Gynecology from 2016 to 2020 were analyzed. Obstetric information, pregnancy complications, and delivery information of pregnant women over 22 weeks of gestation were compared before and during the pandemic. The trends of hypertensive disorder of pregnancy, fetal growth restriction, and APGAR < 7 increased, whereas those of preterm birth and low birth weight decreased during the COVID-19 pandemic. Pregnancy complications and delivery outcomes have worsened during the COVID-19 pandemic in Japan. Social changes caused by unprecedented situations may have massively influenced pregnancy in several ways. Our findings suggest that even in mild lockdowns like those in Japan, the introduction of social fear during the pandemic might negatively impact pregnancy outcomes.

Could efficacy at 1 week after galcanezumab administration for patients with migraine predict responders at 3 months? A real world study. J Neurol 2023; 270:4377-4384. [PMID: 37219606 DOI: 10.1007/s00415-023-11788-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 05/16/2023] [Accepted: 05/17/2023] [Indexed: 05/24/2023]
Abstract
BACKGROUND In real-world studies, it is unclear whether galcanezumab has a significant effect in the first week after administration. METHODS We retrospectively assessed 55 high-frequency episodic migraine (HFEM) and chronic migraine patients who received three galcanezumab doses. Mean changes in the numbers of weekly migraine days (WMDs) during month 1 and migraine days per month (MMDs) after 1-3 months of treatment were obtained. Clinical factors related to a ≥ 50% response rate (RR) at month 3 were analyzed. The prediction of ≥ 50% responders at month 3 using different weekly RRs at week 1 (W1) was evaluated. The RR at W1 was calculated with the following formula: RR (%) = 100 - [(WMDs at W1/baseline WMD) × 100]. RESULTS The number of MMDs significantly improved from baseline to 1, 2 and 3 months. The ≥ 50% RR was 50.9% at 3 months. The number of WMDs decreased significantly from baseline to week 1 (- 1.6 ± 1.7 days), week 2 (- 1.2 ± 1.6 days), week 3 (- 1.0 ± 1.3 days), and week 4 (- 1.1 ± 1.6 days) during month 1. The RR at W1 was largest (44.6 ± 42.2%). The ≥ 30%, ≥ 50% and ≥ 75% RRs at W1 were significantly predictive of a ≥ 50% RR at 3 months. Logistic regression analysis predicting a ≥ 50% RR at month 3 showed that the RR at W1 was the sole contributing factor. CONCLUSION In our study, galcanezumab showed a significant effect in the first week after administration, and the RR at W1 could predict the RR at 3 months.

Abstract
Background The effectiveness of fremanezumab in treating migraine has been demonstrated in randomized controlled trials. However, real-world study results are still limited. Methods We conducted a single-center, observational study that included patients with episodic migraine (EM) and chronic migraine (CM) who received fremanezumab monthly or quarterly over 6-month periods. The primary outcome of this study was to evaluate changes in monthly migraine days (MMD) and responder achievement after treatment with fremanezumab. The secondary aim was to characterize the predictors of responder at 6 months. We also evaluated the effectiveness of fremanezumab in the patients who switched from other calcitonin gene-related peptide (CGRP) monoclonal antibodies, and compared the effectiveness of fremanezumab between the monthly and quarterly dosing groups. One hundred twenty-seven patients with migraine (age, 45.2 ± 12.6 years; 96 women) who received at least one dose of fremanezumab with ≥3 months of follow-up were included. The number of MMD was assessed by headache diary. Results The changes in MMD from baseline at 1, 3, and 6 months were -6.1 ± 4.7, -7.7 ± 4.4, and - 8.5 ± 4.5 days in the total cohort, respectively (p < 0.001). The ≥50%, ≥ 75 and 100% responder rates at 6 months were 67.6, 22.5, and 5.4% in the total cohort, 90.4, 36.5, and 9.6% in the EM group, and 52.2, 14.9, and 1.5% in the CM group, respectively. Fremanezumab was also effective in 35 patients who switched from other CGRP monoclonal antibodies. Quarterly and monthly fremanezumab doses were equally effective in MMD reduction in the EM and CM groups. In the CM group, 65.1% experienced remission to EM after 6 months. Adverse reactions were mild and occurred in 9.5% of total patients. An at least ≥50% reduction in MMD from months 1 to 3 better predicted a ≥ 50% reduction in MMD at 6 months with 90.5% sensitivity and 80.6% specificity (p < 0.001). Conclusion In our real-world study, quarterly and monthly fremanezumab dosing showed both favorable effectiveness and tolerability in patients with migraine.

Abstract
BACKGROUND Real-world data on the effectiveness of calcitonin gene-related peptide monoclonal antibodies (CGRP mAbs) in migraine patients are needed. METHODS We performed a single-center, real-world study with an observation period of up to 12 months (mean 7.5 ± 3.4 months) after CGRP mAb administration. A total of 228 Japanese patients with episodic or chronic migraine (age, 45.9 ± 13.2 years; 184F; 45 erenumab; 60 galcanezumab; 123 fremanezumab) who were treated with CGRP mAbs for at least three months were ultimately included in this study. RESULTS In the total cohort, after CGRP mAb treatment, mean monthly migraine days decreased by 7.2 ± 4.8, 8.3 ± 4.7, and 9.5 ± 5.0 at three, six and 12 months, respectively. The ≥50% monthly migraine day reduction rates at three, six and 12 months were 48.2%, 61.0% and 73.7%, respectively. In the logistic regression analysis, the presence of osmophobia and fewer baseline monthly migraine days contributed to ≥50% responders at three, six and 12 months. The ≥50% responders at three or six months were useful in predicting ≥50% responders at 12 months. In subgroups of patients with difficult-to-treat migraine (those with medication overuse headache or psychiatric comorbidities) and previous CGRP mAb users, monthly migraine days were substantially reduced over 12 months. There was no difference in monthly migraine day reduction over 12 months among three different CGRP mAbs. Adverse reactions were observed in 28 (12.3%) patients, with injection site reactions being the most common (n = 22) though generally mild in severity. CONCLUSION This real-world study confirmed the efficacy and safety of three different CGRP mAbs for prophylactic treatment of patients with migraine.

Abstract
Pregnant women presumably gather information about the coronavirus disease 2019 (COVID-19) from various sources. However, it is difficult for pregnant women who are not medical professionals to source the appropriate information because of the infodemic related to the COVID-19 pandemic. Therefore, the objective of our study was to investigate how pregnant women gathered information about COVID-19 and COVID-19 vaccination. To address this issue, we conducted an online questionnaire survey between 5 October and 22 November 2021, which was approved by the Ethics Committee of Nihon University School of Medicine. We received 4962 responses after excluding 1179 insufficient answers. Our study found that age, occupation, and infection-risk anxiety influenced the selection of media for obtaining information. Pregnant women who were older, medical professionals, public servants, or educators tended to rely on specialized medical websites, whereas housewives tended to use mass media, social media, and sources with uncertain scientific evidence. Additionally, the number of weeks of gestation and the method of conception (natural or assisted reproductive conception) affected the selection of media. The accessibility of COVID-19 information for pregnant women was determined by their social background and pregnancy status. We need to continue making efforts to ensure that appropriate information is readily available to pregnant women and their families.

Abstract
We sought to estimate the prevalence of metabolic syndrome (MS) in the urban population of Mongolia and suggest a preferred definition. This cross-sectional study comprised 2076 representative samples, which were randomly selected to provide blood samples. MS was defined by the National Cholesterol Education Program's Adults Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF), and the Joint Interim Statement (JIS). The Cohen's kappa coefficient (κ) was analyzed to determine the agreement between the individual MS components using the three definitions. The prevalence of MS in the 2076 samples was 19.4% by NCEP ATP III, 23.6% by IDF, and 25.4% by JIS criteria. For men, moderate agreement was found between the NCEP ATP III and waist circumference (WC) (κ = 0.42), and between the JIS and fasting blood glucose (FBG) (κ = 0.44) and triglycerides (TG) (κ = 0.46). For women, moderate agreement was found between the NCEP ATP III and high-density lipoprotein cholesterol (HDL-C) (κ = 0.43), and between the JIS and HDL-C (κ = 0.43). MS is highly prevalent in the Mongolian urban population. The JIS definition is recommended as the provisional definition.

Abstract
INTRODUCTION Hematochezia is observed frequently in daily practice. However, natural hemostasis often prevents identification of the bleeding source during observations. This study was conducted to clarify risk factors related to rebleeding in hematochezia patients without an identified cause of bleeding. METHODS We analyzed patients who were admitted to Dokkyo Medical University Hospital during April 1, 2009, through March 31, 2015, with the chief complaint of hematochezia. Main outcome measures included the rebleeding rate and the period until rebleeding in hematochezia patients without an identified bleeding source. RESULTS We selected 159 patients for analyses. Rebleeding was observed in 46 (28.9%) of 159 patients. The median period until first rebleeding was 166 days (2-3,046 days). Univariate analysis indicated that risk factors for rebleeding were male gender (p = 0.029), higher age (p = 0.023), antithrombotic medicines (p = 0.047), lower hemoglobin on admission (p = 0.024), and the presence of diverticula (p = 0.002). Multivariate analysis indicated the presence of diverticula (p = 0.023) and male gender (p = 0.043) as rebleeding risk factors. DISCUSSION/CONCLUSION In patients with hematochezia of unknown origin, risk factors for rebleeding indicated in this study, especially the presence of diverticula and male gender, should be given particular attention by physicians.

Abstract
BACKGROUND AND AIM Small gastric subepithelial lesions (SELs) are sometimes encountered in daily esophagogastroduodenoscopy (EGD) practice, but whether once-annual or twice-annual endoscopy can provide sufficient follow-up remains unclear. Because follow-up based on small-SEL characteristics is important, this study clarified the natural history of gastric SELs less than 20 mm. METHODS This retrospective multicenter observation study conducted at 24 Japanese hospitals during April 2000 to March 2020 examined small gastric SELs of ≤20 mm diameter. The primary outcome was the rate of size increase of those SELs detected using EGD, with growth times assessed irrespective of SEL pathological diagnoses. RESULTS We examined 824 cases with tumors of 1-5 mm diameter in 298 (36.2%) cases, 6-10 mm in 344 (41.7%) cases, 11-15 mm in 112 (13.6%) cases, and 16-20 mm in 70 (8.50%) cases. An increase of small gastric SELs was observed in 70/824 patients (8.5%). The SELs larger than 6 mm increased, even after 10 years. No-change and increasing groups had no significantly different malignant findings at diagnosis. In cases of gastrointestinal stromal tumors (GISTs), internal cystic change in endoscopic ultrasound (EUS) is a risk factor for an increased tumor size. The predictive tumor growth cutoff size at initial diagnosis was 13.5 mm. CONCLUSIONS Small gastric SELs less than 20 mm have an approximately 8.5% chance of increase. Predictive markers for GIST growth are tumor size ≥13.5 mm and internal cystic change in EUS.

Abstract
BACKGROUND/PURPOSE The aim of this study is to clarify the relation between the incision size for endoscopic sphincterotomy (EST) and common bile duct stone (CBDS) recurrence. METHODS Patients who underwent elective endoscopic treatment for CBDS between January 2013 and December 2017 were enrolled, excluding those who met the exclusion criteria. The clinical characteristics were investigated using propensity score matching analysis. RESULTS A total of 243 patients were investigated. Propensity scores were calculated using multinomial logistic regression with five relevant variables (age, gender, follow-up time, maximum stone size, and bile duct diameter), which led to extraction of 188 cases to compose cohorts of the small and medium EST incision groups. The CBDS recurrence rate was 17.0% in the small incision group and 6.4% in the medium incision group. Multivariate analysis identified the medium incision as an independent predictor of CBDS recurrence (hazard ratio 0.350, 95% confidence interval 0.133-0.922, P = .034). The CBDS non-recurrence rate of the medium incision group was significantly higher than that of the small incision group (log-rank test P = .019). CONCLUSIONS Our findings suggest that the CBDS recurrence rate was lower in EST with medium incision size than with small incision size.

Abstract
OBJECTIVES The purpose of this study was to identify the effective intervals of worksite dental check-ups to reduce cumulative dental expenditures (CDEs) and cumulative medical expenditures (CMEs), based on 12 years of follow-up dental check-ups. SETTING, DESIGN AND PARTICIPANTS A longitudinal study was conducted between 2002 and 2014 fiscal years. A total of 2691 full-time employees (2099 males and 592 females) aged 20-59 years in a manufacturing company in Japan were recruited. PRIMARY AND SECONDARY OUTCOME MEASURES Based on the follow-up of 12-year dental check-ups, the interval of dental check-ups visits was classified into the following categories: 'Once per year' as the regular group, 'At least once per 2 years' as the subregular group and others as the irregular group. CDEs and CMEs per capita were examined by the three groups of dental check-ups interval after adjustment for sex, age, occupation and total CMEs at baseline. For sensitivity analysis, decayed teeth, missing teeth and Community Periodontal Index were added as adjustment factors. RESULTS Compared with the irregular group, the pooled CDEs (including dental check-ups fee) per capita in the subregular group (OR 0.91, 95% CI 0.85 to 0.98) and regular group (OR 0.87, 95% CI 0.81 to 0.93) were significantly lower overall. The younger adults in the subregular group and younger-aged and middle-aged adults in the regular group had significantly lower CDEs. Sensitivity analysis confirmed these findings. CONCLUSIONS Our findings suggest that regular and subregular worksite dental check-ups were related to reduction of CDEs. It is important to promote a yearly interval between dental check-ups.

Measuring optimal ultrasound speed using endoscopic ultrasound in patients with chronic pancreatitis, including early stage. Dig Endosc 2022; 34:1214-1221. [PMID: 35108413 DOI: 10.1111/den.14261] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2021] [Revised: 01/17/2022] [Accepted: 01/30/2022] [Indexed: 02/08/2023]
Abstract
OBJECTIVES Ultrasound speed (USS) correction improves image quality by estimating the optimal USS correcting the deviation from a predetermined USS. This study assessed USS differences between chronic pancreatitis (CP), early CP (ECP), and normal pancreas when using endoscopic ultrasound (EUS). The usefulness of measuring optimal USS was evaluated for patients with CP, including early stage patients. METHODS This study enrolled 116 consecutive patients for whom USS was measured using an EUS system. The USS correction principle is generation of a B-mode image by changing the USS in all ranges while correcting the delay in the received data. Final diagnoses were made according to the Japanese diagnostic criteria for CP in 2019. They were classified as CP, ECP, or normal. We compared USS applied for these three groups. RESULTS The medians and ranges of USS values for patients in the normal, ECP, and CP groups were 1506.0 (1407-1600) m/s, 1580.0 (1520-1630) m/s, and 1574.0 (1537-1610) m/s, respectively. The USS values of the ECP and CP groups were significantly higher than those of the normal group (P < 0.001). Analyses of the receiver operating characteristic curve in the normal pancreas, ECP, and CP revealed the area as 0.957, with specificity and sensitivity of 95.9% and 87.5%, respectively, using the USS of 1535 m/s as a cut-off. CONCLUSION Measurement of USS might be particularly useful for distinguishing between normal and ECP imaging.

Impact of health literacy on anxiety and depressive symptoms in pregnant women in Japan during the COVID-19 pandemic. Sci Rep 2022; 12:14042. [PMID: 35982222 PMCID: PMC9386675 DOI: 10.1038/s41598-022-18405-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Accepted: 08/10/2022] [Indexed: 11/18/2022] Open
Abstract
To investigate the relationships between communicative and critical health literacy (CCHL) and anxiety and depressive symptoms (ADs) in pregnant women during the coronavirus disease 2019 (COVID-19) pandemic. A cross-sectional study was conducted and 5466 pregnant women responded in Japan in September 2020. A Kessler 6 scale (K6) score ≥ 10, an Edinburgh Postnatal Depression Scale (EPDS) score ≥ 13, and four CCHL groups were analyzed using a logistic regression model and trend test. The proportions of pregnant women with a K6 score ≥ 10 and EPDS score ≥ 13 were 13.5 and 15.4%, respectively. In comparisons with the low CCHL group, the adjusted odds ratio (95% CI) for anxiety symptoms was 0.770 (0.604–0.982) in the high CCHL group, while those for depressive symptoms were 0.777 (0.639–0.946), 0.665 (0.537–0.824), and 0.666 (0.529–0.838) in the lower, higher, and high CCHL groups (all p < 0.05), respectively, after adjustments for potential confounding factors, such as age, weeks of gestation, complications, history, number of children, marital status, education, employment, and income. Higher CCHL was associated with significantly lower adjusted odds ratios for anxiety (p for trend = 0.019) and depressive symptoms (p for trend < 0.001). These results suggest a relationship between CCHL and ADs in pregnant women during the COVID-19 pandemic.

Abstract
HD patients underwent SAVR-BP for AS (hospital mortality, 8.8%; 5-year mortality, 42.1%). Preoperative risk factors for 5-year mortality: age, hyperlipidemia, LVDd, LVDs, and Japan SCORE. Postoperative risk factors for 5-year mortality: length of ICU stay, and albumin level at discharge.
Background Limited studies have assessed the factors affecting prognosis in hemodialysis (HD) patients who undergo surgical aortic valve replacement with a bioprostheses (SAVR-BP). This study aimed to evaluate the outcomes of HD patients who had undergone SAVR-BP for aortic stenosis (AS) and identify the risk factors for mortality. Methods This retrospective study included 57 HD patients who had undergone SAVR-BP for AS between July 2009 and December 2020. Multivariate logistic regression was used to predict factors associated with mid-term outcomes and death or survival. Kaplan − Meier curves were also generated for mid-term survival. Results The in-hospital mortality rate was 8.8%, and the 5-year mortality rate was 42.1%. The independent predictors of 5-year mortality were preoperative age (hazard ratio [HR], 1.57; 95% confidence interval [CI], 1.175–2.083, p = 0.002), hyperlipidemia (HR, 0.02; 95% CI, 0.002–0.297, p = 0.004), left ventricular diastolic diameter (HR, 1.74; 95% CI, 1.142–2.649, p = 0.010), left ventricular systolic diameter (HR, 0.61; 95% CI, 0.392–0.939, p = 0.025), and Japan SCORE (HR, 1.28; 95% CI, 1.052–1.563, p = 0.014). The postoperative predictors included intensive care unit stay (HR, 1.11; 95% CI, 1.035–1.194, p = 0.004) and albumin level (HR, 0.38; 95% CI, 0.196–0.725, p = 0.003). Conclusions The 5-year prognosis of HD patients undergoing SAVR may be improved by early diagnosis (before the occurrence of LV hypertrophy/enlargement) and nutritional management with oral intake to alleviate postoperative hypoalbuminemia. Registration number of clinical studies: UMIN000047410.

Abstract
To investigate the vaccination status and adverse reactions to the COVID‐19 vaccine among pregnant women in Japan, we conducted an online questionnaire survey from October 5 to November 22, 2021. The number of participants in the online survey was 6576. Of the participants, 4840 (73.6%) were vaccinated twice, and 557 (8.5%) were vaccinated once. A total of 1179 (17.9%) responders had never been vaccinated against COVID‐19. The most frequent adverse reaction was local pain at the injection site. The incidence of local adverse reactions was almost identical after the first and the second vaccinations, while systemic reactions, such as fever and fatigue/malaise, and adverse reactions outside the vaccination site such as headache and arthralgia, were more frequent after the second vaccination than after the first vaccination. Regarding the obstetrical complications, uterine tension and/or contraction was observed in 1.65% of the pregnant women after the first vaccination and in 2.98% after the second vaccination, and uterine pain appeared in 1.06% of the pregnant women after the second vaccination. However, serious symptoms, such as hemorrhage, decreased fetal movement, edema, increased blood pressure, and amniorrhexis, were seen in less than 1% of vaccinated women after both the first and second vaccinations. This study clarified the characteristics of vaccination, adverse reactions, and obstetrical symptoms in pregnant women in Japan who had the COVID‐19 vaccine up to the second dose. As a booster vaccination is currently underway, further study is needed to improve the management of pregnant women during the current pandemic.

The Risk Factors for Progression to Chronic Pancreatitis in Patients with Past-History of Acute Pancreatitis: A Retrospective Analysis Based on Mechanistic Definition. J Clin Med 2022; 11:jcm11082209. [PMID: 35456301 PMCID: PMC9032682 DOI: 10.3390/jcm11082209] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/06/2022] [Revised: 04/09/2022] [Accepted: 04/13/2022] [Indexed: 12/12/2022] Open
Abstract
Background: According to the mechanistic definition, the history of acute pancreatitis (AP) is a risk factor for chronic pancreatitis (CP). However, the etiology and severity of previous AP involved in the progression to CP have not been clarified. Here, we investigated risk factors for the progression to CP in patients with past-history of AP. Methods: Sixty-four patients with AP who were followed-up for at least two years at our institution between April 2009 and March 2017 were enrolled. The multivariate analysis was performed based on the risk factors extracted by univariate analysis. Results: Among the 64 patients, 13 patients (20.3%) progressed to CP (PCP group), while 48 did not (non-PCP group). Regarding the etiology of AP, rate of alcohol AP was significantly higher in the PCP group (76.9% vs. 33.3%, p = 0.003). In univariate analysis, smoking, number of previous AP, and alcohol consumption and drinking habits (Alcohol Use Disorders Identification Test-Concise; AUDIT-C) were identified as factors associated with progression to CP. Furthermore, multivariate analysis showed that AUDIT-C ≥ 6 points (male) and 4 points (female) after AP was a significant risk factor for CP (p = 0.003). Conclusions: Our results indicated that AUDIT-C ≥ 6 points (male) and 4 points (female) after AP was a risk factor in the process of progression to CP in patients with past-history of AP.

Abstract
Objective Multiple chemical sensitivity (MCS) is a form of chemical intolerance in which various systemic symptoms are triggered by exposure to a variety of chemical substances. Although migraine has been associated with central sensitivity syndrome, the relationship between MCS and migraine has not been studied. We assessed the frequency of MCS and its related factors in patients with migraine. Methods We performed a cross‐sectional study that included 95 patients (14 M/81 F; age, 45.4 ± 12.4 years) out of 100 consecutive patients with migraine from our outpatient headache clinic. MCS was defined as having a combination of Q1 ≥ 30, Q3 ≥ 13, and Q5 ≥ 17 on the quick environment exposure sensitivity inventory (QEESI; Japanese version). Central sensitization inventory‐A scores >40 were considered an indication of central sensitization. Headache‐related disability and psychological distress were evaluated with the Migraine Disability Assessment score (MIDAS) and Kessler Psychological Distress Scale (K6), respectively. Results MCS was identified in 20% of patients with migraine; however, none had previously been diagnosed with MCS. The MCS‐positive group had higher rates of photophobia, osmophobia, visual aura, sensory aura, and central sensitization and higher MIDAS and K6 scores than the MCS‐negative group. A logistic regression analysis showed that osmophobia, sensory aura, and central sensitization were significant contributors to MCS. Conclusion We showed that MCS was observed in 20% of patients with migraine, and our study results may indicate a possible association of MCS with central sensitization and hypersensitivity‐related symptoms in patients with migraine.

Abstract
The maximum limit on overtime working hours for physicians will be applied from 2024. To explore sociodemographic and work-related factors influencing overtime work among cardiovascular surgeons (CS) in Japan. This cross-sectional study included 607 CS who responded to an online survey. Working hours were categorized into ≤60 hours, 60-79 hours, and ≥80 hours per week according to Japan Ministry of Health, Labour and Welfare. Adjusted odds ratios (aOR) were calculated using a multinomial analysis with stepwise reduction after adjustment for potential confounders. Compared to ≤60 hours, significant factors related to 60-79 hours and ≥80 hours per week were age groups of 30s to 50s versus 60s (aOR: 7.48-3.22 and 23.64-4.87), management with cardiovascular drugs (aOR: 1.87 and 5.80), and postoperative wound management (aOR: 0.47 and 0.16), respectively. Significantly related informed consent for surgery (aOR: 3.29) was seen in 60-79 hours. Contrarily, CS who worked for ≥80 hours took on-duty 5 times or more per month (aOR: 3.89), performed night or holiday calls 20 times or more per month (aOR: 2.26), and attended the intensive care unit (aOR: 3.12). These findings suggest that younger, and some non-surgical work-related factors could influence long working hours among CS.

Abstract
A cross-sectional study of 21,665 Japanese residents was performed to investigate the prevalence of central sensitization syndromes (CSS). CSS were assessed using the Central Sensitization Inventory (CSI-A). CSS were defined as a CSI-A score of 40 or higher. Age, sex, district, 10 CSS-related diseases (CSI-B), lifestyle, and mental factors were rated in a self-reported survey. The prevalence of CSS and its relationship with potential factors were examined by sex using descriptive and logistic regression models. The prevalence of CSS was 4.2% in all participants and was significantly higher in women (4.9%) than in men (2.7%). Adjusted odds ratios correlated with CSS for an age of 80–97 years versus 60–79 years (2.07 and 2.89), one or more CSI-B diseases (3.58 and 3.51), few sleeping hours (2.18 and 1.98), high perceived stress (5.00 and 4.91), low (2.94 and 2.71) and high (0.45 and 0.66) resilience versus moderate resilience, and exercise habits (0.68 and 0.55) in men and women (all P < 0.05). The relationship between CSS and age 20 and 59 years, ex-smokers, coffee intake, and alcohol intake differed by sex. The prevalence of CSS was estimated to be low in the healthy population. CSS correlated with CSS-related diseases and some positive and negative factors.

Abstract
The Mayo endoscopic subscore (MES) is a major endoscopic scoring system used to assign a status of mucosal inflammation and disease activity to patients with ulcerative colitis (UC). Using interobserver reliability (IOR), this study clarified the difficulties for endoscopic observers imposed by MES parameters used for the endoscopic evaluation of UC in histological remission. First, 42 endoscopists of four observer groups examined each MES parameter, which were evaluated from endoscopically obtained images of 100 cases as Grade 0 or 1 of the Nancy histological index of histopathological inflammation. Then, IOR was assessed using multiple κ statistics for each finding of MES. The results showed that IOR among all the observers was slight or fair for all the parameters, indicating a low IOR. The experts of the UC practice group had "moderate" or higher IOR for seven of the nine parameters, whereas "slight" or "fair" results were found for all parameters by the trainee group. The IOR for each MES parameter was calculated separately for the observer groups. All the groups showed "slight" or "fair" for "Erythema" and "Decreased vascular pattern". Large differences between the endoscopists were found in the IOR for the MES parameters in UC in histological remission. Even among UC practice experts, the IOR was low for "Erythema" and "Decreased vascular pattern".

Abstract
In Japan, reports on the association of individual characteristics, and geographical distance and time with clinical outcomes for neurological emergencies involving helicopter emergency medical services (HEMS) are scarce. Using Tochigi HEMS data (2010-2018), we assessed the characteristics of 1,170 emergency neurological patients (e.g., stroke, neurotrauma, and seizure) at the base hospital, which covered 58% of all HEMS patients in the prefecture. After initial treatment in the emergency room, emergency physicians confirmed the clinical outcomes of each patient compared to those at the incident sites (recovery/non-recovery). We calculated the geographic distance from the base hospital to each incident site, and estimated and adjusted odds ratios (aOR) and 95% confidence intervals (CI) for non-recovery against distance. The mean distance between the incident site and base hospital was 22.0 ± 11.7 km, and 77.4% of patients recovered following initial treatment. Two peak age groups were observed among emergency neurological diseases, including seizures in patients who were aged < 5 years and stroke and neurotrauma in patients who were aged 70-80 years. The percentages of stroke, traumatic head and brain injury, and seizure were 35.8%, 29.2%, and 22.8%, respectively. The incidence of stroke (aOR = 11.8, 95% CI 6.86-20.3) and neurotrauma (aOR = 4.86, 95% CI 2.78-8.51) independently predicted a poor prognosis. However, no significant association was observed with the distance from the base hospital. Therefore, in the Tochigi prefecture, geographical disparities may not affect the short-term prognosis of patients with neurological emergencies who were transported by HEMS.

Abstract
OBJECTIVE Although heated tobacco products (HTPs) have become popular worldwide, research on occupational differences in smoking HTPs remains scarce. We aimed to examine the prevalence of smoking HTPs among a working population in Japan. SETTING, DESIGN AND PARTICIPANTS In 2018, we conducted a cross-sectional study comprised of 7714 retail business workers in the service industry in Japan. PRIMARY AND SECONDARY OUTCOME MEASURES For the definition of smoking HTPs, we identified current HTP smokers who only smoked HTPs, using five mutual categories of current smoking status (never, former, HTPs only, combustible cigarettes only and dual smokers who smoked both combustible cigarettes and HTPs). Occupational classes were classified into office workers (eg, upper non-manual workers) and other workers. ORs and 95% CIs of office workers were estimated for HTP usage, adjusted for age, sex, employment type and cigarette smoking-related health knowledge. RESULTS The overall prevalence of smoking HTPs was 3.0% (male 5.0%, female 2.2%). The prevalence of HTP smokers differed across occupational classes (5.6% in office workers vs 2.5% in others; p<0.05). Compared with other workers, the adjusted odds of office workers for smoking HTPs remained elevated (OR: 1.97, 95% CI: 1.40 to 2.77). Sensitivity analyses with workers of all smoking status showed the same pattern. When stratified by sex, the occupational difference only remained significant in male workers. CONCLUSIONS We found a positive occupational difference in smoking HTPs, particularly among male workers in the retail sector in Japan. National tobacco control should explicitly address this occupational gap and further encourage individuals to quit smoking.

Abstract
BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has negatively affected the mental health of the general population. OBJECTIVE We investigated the determinants of quality of life (QOL) in Parkinson's disease (PD) patients during the COVID-19 pandemic. METHODS Impacts of lifestyle changes due to the COVID-19 pandemic on 100 patients with PD and their caregivers/spouses were assessed. The Hospital Anxiety and Depression Scale was used to assess anxiety and depression. The physical component summary (PCS) and mental component summary (MCS) scores of the short form (SF)-8 were used to evaluate health-related QOL. RESULTS Regarding health-related QOL, physical function, role physical, general health, vitality and the PCS score were significantly worse in PD patients than in caregivers. Worsening of PD-related symptoms, increased stress, and decreased physical activity were observed in 29.0%, 37.0% and 44.0% of PD patients, respectively. Sixteen patients (16.0%) experienced problems with hospital access, but none reported medication shortages. Strong concerns about COVID-19 were reported by 47.0% of caregivers and 50.0% of PD patients. In PD patients, increased gait disturbance and rigidity, disease severity, smoking, the levodopa equivalent dose and decreased body weight predicted a worse PCS score; anxiety, depression, female sex, stress and long disease duration predicted a worse MCS score. In caregivers, age and smoking contributed to a worse PCS score; depression, stress and worsening patient mood contributed to a worse MCS score. CONCLUSION We report the negative impacts of the COVID-19 pandemic on health-related QOL and its determinants in PD patients and their caregivers.

Investigating the relationships between the burden of multiple sensory hypersensitivity symptoms and headache-related disability in patents with migraine. J Headache Pain 2021; 22:77. [PMID: 34281498 PMCID: PMC8287675 DOI: 10.1186/s10194-021-01294-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 07/12/2021] [Indexed: 11/10/2022] Open
Abstract
Objective Sensory hypersensitivities such as photophobia, phonophobia, and osmophobia are common in patients with migraine. We investigated the burden of these multiple sensory hypersensitivities in migraine. Methods In this cross-sectional study, 187 consecutive patients with migraine (26 men/161 women; age, 45.9 ± 13.2 years) were included. Sensory hypersensitivity symptoms such as photo−/phono−/osmophobia and accompanying symptoms were determined by neurologists in interviews. The Migraine Disability Assessment (MIDAS) was used to assess headache-related disability. The Kessler Psychological Distress Scale (K6) was also administered. Results Photophobia, phonophobia and osmophobia were observed in 75.4%, 76.5% and 55.1% of the patients with migraine, respectively. A significant overlap in sensory hypersensitivities (photo−/phono−/osmophobia) was found; the proportions of patients with 2 and 3 coexisting sensory hypersensitivities were 33.2% and 41.7%, respectively. The MIDAS score was higher in those with 3 sensory hypersensitivity symptoms than in those with 0 to 2 sensory hypersensitivity symptoms. A generalized linear model with ordinal logistic regression analysis revealed that multiple sensory hypersensitivities, younger age, more migraine days per month, and a higher K6 score were significantly related to the higher MIDAS score. Conclusion Our study showed that sensory hypersensitivities commonly occur and overlap in patients with migraine and that multiple sensory hypersensitivity symptoms have a significant impact on headache-related disability.

Abstract
AIM To evaluate psychological stress among pregnant and puerperal women in Japan during the coronavirus disease 2019 (COVID-19) pandemic. METHODS In this cross-sectional study, we recruited pregnant women and puerperal women who delivered between January and September 2020 in Japan, using an online questionnaire. Participants were divided into low, middle, and high groups according to the degree of the epidemic in their region of residence. Related factors were analyzed using the chi-squared test. The relationship between COVID-19 epidemic regions and depression risks and anxiety using the Edinburgh Postnatal Depression Scale (EPDS) and Kessler 6 scale (K6) was evaluated using a univariate and multivariable logistic regression model. RESULTS Overall, 7775 cases, including 4798 pregnant and 2977 puerperal women, were analyzed. The prevalence of high EPDS and K6 scores was significantly increased in pregnant women in the high than those in the low epidemic regions (EPDS: adjusted odds ratio [aOR] 1.453, 95% confidence interval [CI] 1.205-1.753; K6: aOR 1.601, 95% CI 1.338-1.918). There was no difference in EPDS score, but the prevalence of high K6 scores was significantly increased in puerperal women in the high than those in the low epidemic regions (aOR 1.342, 95% CI 1.066-1.690). Further, restriction on going to their hometown for delivery increased the prevalence of high EPDS scores among pregnant (aOR 1.663, 95% CI 1.296-2.133) and puerperal women (aOR 1.604, 95% CI 1.006-2.557). CONCLUSIONS Decreased support due to the COVID-19 pandemic affected the psychological status of pregnant and puerperal women; hence, investing medical resources in their healthcare essential.

The physical and mental burden on obstetricians and gynecologists during the COVID-19 pandemic: A September 2020 questionnaire study. J Obstet Gynaecol Res 2021; 47:3001-3007. [PMID: 34137114 PMCID: PMC8447212 DOI: 10.1111/jog.14878] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Accepted: 05/27/2021] [Indexed: 11/30/2022]
Abstract
Aim The aim of this study was to clarify the physical and mental burden of the COIVD‐19 pandemic on obstetricians and gynecologists in Japan and to identify factors that increase the burden of their psychological stress. Methods A web‐based questionnaire was sent to obstetricians and gynecologists in Japan via email and social media to collect voluntary responses. This survey was conducted from September 1 to 30, 2020. Results A total of 852 valid responses were included in the analysis; 76% (644) of the physicians felt that the COVID‐19 pandemic caused them physical and mental stress equal to or greater than the most severe disaster they had ever experienced. Physicians who reported high mental and physical stress were more likely to be in areas with high numbers of infected patients (odds ratio (OR) 1.571, p = 0.012). Physicians experienced great stress to the point of wearing heavy personal protective equipment during routine vaginal deliveries by mothers with no COVID‐19 symptoms. This trend was markedly pronounced for physicians working in regions with fewer cases of COVID‐19 infection. Conclusions Obstetricians and gynecologists who reported high mental and physical stress were more likely to be in areas with high numbers of infected patients. One potential reason for this may be that they were required to wear more personal protective equipment than necessary. Infection control methods that ensure the safety of obstetricians and gynecologists while not causing unnecessary physical or psychological stress are needed.

Zonisamide effects on sleep problems and depressive symptoms in Parkinson's disease. Brain Behav 2021; 11:e02026. [PMID: 33399276 PMCID: PMC7994695 DOI: 10.1002/brb3.2026] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/06/2019] [Revised: 12/09/2019] [Accepted: 12/20/2020] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND We aimed to evaluate the effect of zonisamide (ZNS) on motor symptoms and nonmotor symptoms such as depressive symptoms and sleep problems in Parkinson's disease (PD) patients with or without tremor. METHODS We conducted a 3-month, open-label study to assess the effects of ZNS on motor symptoms, depressive symptoms and sleep problems. Twenty levodopa-treated PD patients with motor fluctuation completed the study. Patients received 25-50 mg/day of ZNS and were assessed for the Japanese version of the Movement Disorder Society Revision of the Unified PD Rating Scale (MDS-UPDRS) parts I, III, and IV, PD Sleep Scale (PDSS)-2, Beck depression inventory-2 (BDI-II), and PD Questionnaire (PDQ-8) at baseline and after 1, 2 and 3 months of treatment. Patients were categorized into the tremor group and nontremor group to assess changes in clinical parameters. RESULTS At 3 months, the scores on the MDS-UPDRS parts I, III and IV significantly improved and off-time reduced compared to baseline. Additionally, the PDSS-2 total score significantly decreased at 3 months. Although there were no significant differences in changes in UPDRS part I, III, or IV between the groups after ZNS treatment, the tremor group had significant improvements in PDSS-2 at 3 months and BDI-II at 1, 2 and 3 months compared with the nontremor group. CONCLUSION We showed the beneficial effects of ZNS on motor symptoms and sleep problems in levodopa-treated PD patients with motor fluctuation. ZNS may be more effective for several nonmotor symptoms in PD patients with tremor compared with those without tremor.

Abstract
Background The role of central sensitization in refractory pain-related diseases has not yet been clarified. Methods We performed a multicenter case-controlled study including 551 patients with various neurological, psychological, and pain disorders and 5,188 healthy controls to investigate the impact of central sensitization in these patients. Symptoms related to central sensitization syndrome (CSS) were assessed by the Central Sensitization Inventory (CSI) parts A and B. Patients were categorized into 5 groups based on CSI-A scores from subclinical to extreme. The Brief Pain Inventory (BPI), addressing pain severity and pain interference with daily activities, and the Patient Health Questionnaire (PHQ)-9, assessing depressive symptoms, were also administered. Results CSI-A scores and CSI-B disease numbers were significantly greater in patients than in controls (p < 0.001). Medium effect sizes (r = 0.37) for CSI-A scores and large effect sizes (r = 0.64) for CSI-B disease numbers were found between patients and control groups. Compared with the CSI-A subclinical group, the CSI-A mild, moderate, severe, and extreme groups had significantly higher BPI pain interference and severity scores, PHQ-9 scores, and CSS-related disease numbers based on ANCOVA. Greater CSI-B numbers resulted in higher CSI-A scores (p < 0.001) and a higher odds ratio (p for trend <0.001). CSS-related symptoms were associated with pain severity, pain interference with daily activities, and depressive symptoms in various pain-related diseases. Conclusions Our findings suggest that CSS may participate in these conditions as common pathophysiology.

Abstract
OBJECTIVE To examine the association between the risk of postpartum hemorrhage (PPH) and poor uterine contractility, which is suggested by the characteristics of labor. METHODS This case-control study used cases recorded in the Japan Perinatal Registry database during the period 2013-2016. After exclusion of women with specified known risk factors for PPH, we enrolled 174 082 primiparas who had a full-term live singleton vaginal birth. Participants were classified into four classes according to the diagnosis of abnormal labor patterns and use of uterotonics. χ2 tests were used to compare PPH cases with controls, and odds ratios (OR) were calculated by univariate and multivariate analyses. RESULTS Among the enrolled women, 10 508 (6.0%) had PPH. Abnormal labor patterns were significantly associated with an increased risk of PPH. Compared with women without any abnormal labor patterns who had not used uterotonics, women with abnormal labor patterns were at a significantly increased risk for PPH regardless of whether they had used uterotonics (adjusted OR 1.23, 95% confidence interval [CI] 1.10-1.37) or not (adjusted OR 1.30, 95% CI 1.23-1.37). CONCLUSION Our study suggests that among low-risk women with PPH, poor uterine contractility in labor could be a significant predisposing risk factor for PPH.

Clinical characteristics, treatment methods and prognoses of patients with oral squamous cell carcinoma in Japanese population: a single institution retrospective cohort study. BMC Geriatr 2020; 20:487.

Abstract
BACKGROUND The status of oral cancer therapy in elderly patients in Japan, where ageing is rapidly progressing, may serve as a model for other countries with similar demographics. There is controversy over what kind of treatment should be applied and how aggressively it should be applied to very elderly patients who have exceeded the average life expectancy. Given that 85 years is approximately the overall Japanese life expectancy at birth, we considered a threshold of 85 years and hypothesized that the prognosis of oral squamous cell carcinoma (SCC) patients aged ≥85 years was not inferior to that of those < 85 years. The aim of the present study was to investigate the clinical characteristics, treatment methods, and prognoses of Japanese oral SCC patients aged ≥85 years. METHODS A retrospective cohort study was performed. The data of patients with primary oral SCC (n = 358) from 2005 to 2018 in our institute were extracted from electronic medical records. A total of 358 patients with oral SCC were divided into two groups (≥85 years group [n = 26] and < 85 years group [n = 332]) based on the age threshold of 85 years at the first visit. Kaplan-Meier survival analyses and Cox proportional hazard models were used to analyse overall survival (OS) and hazard ratios (HRs) according to age group, treatment, and TNM classification. RESULTS There was no difference in the 5-year OS rate between the ≥85 years and < 85 years groups (80.8% vs. 82.2%, P = 0.359). This finding was the same in the operative (94.7% vs. 85.8%, P = 0.556) and non-operative (42.9% vs. 33.2%, P = 0.762) groups, indicating that age did not affect prognosis. Mortality was lower in the operative group than in the non-operative group (adjusted HR: 0.276, 95% CI: 0.156-0.489, P < 0.001), suggesting that surgery is a superior method. However, non-surgical treatment was selected at a higher rate in the ≥85 years group (26.9% vs. 11.1%, P = 0.028). CONCLUSIONS This study suggests the prognosis of ≥85-year-old patients was not inferior to that of < 85-year-old patients. We recommend that surgery as the first choice treatment for ≥85-year-old patients with oral SCC who can tolerate surgery should be performed.

Abstract
OBJECTIVE We hypothesized that, in migraine patients, central sensitization (CS) could be associated with comorbid restless legs syndrome (RLS). METHODS We conducted a case-control study including 186 migraine patients and 186 age- and sex-matched healthy controls. Symptoms related to CS syndrome were assessed by the Central Sensitization Inventory (CSI). Individuals with CSI Part A (CSI-A) scores ≥ 40 were defined as having CS. For patients with migraine, the Brief Pain Inventory (BPI) and Patient Health Questionnaire (PHQ)-9 were administered. In the patient group, RLS and migraine were diagnosed through face-to-face interviews. RESULTS Among migraine patients, 26 (14.0%) suffered from chronic migraine. The mean disease duration was 23.7 ± 11.8 years. Migraine patients showed a higher rate of CS (21.0% vs. 8.6%) than healthy controls, with an adjusted odds ratio (AOR) of 3.039 (95% confidence interval (CI) 1.560-5.992; p = 0.001). Migraine patients in the CS group had higher rates of smoking, chronic migraine and RLS and higher BPI and PHQ-9 scores than migraine patients in the non-CS group. The use of acute and preventive treatment for migraine did not significantly differ between the CS and non-CS groups. Multivariable analysis identified the presence of RLS (AOR, 28.471; 95% CI 6.438-125.918; p < 0.001) and the BPI pain interference score (AOR, 1.398; 95% CI 1.061-1.843; p = 0.017) as the significant determinants of CS among migraine patients. CONCLUSION Migraine patients were 3 times more likely to have CS than healthy controls. Our study results showed an association between RLS and CS in migraine patients.

Recent Increasing Incidence of Early-Stage Cervical Cancers of the Squamous Cell Carcinoma Subtype among Young Women. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17207401.

Abstract
Few studies have reported on the increase in cervical cancer incidence in Japan. We aimed to determine the relevant trends in the metropolitan regions of Japan and to identify the population with the highest risk, based on histological subtype, cancer stage, and diagnostic processes. Using population-based data (2009–2013), we identified 2110 women, aged ≥20 years, with cervical cancer. We estimated the age-standardized and age-specific incidence rates of cervical cancer for the study period based on the 1985 national model population. The average annual percent change (AAPC) and 95% confidence interval (CI) were calculated using the joinpoint regression analysis. We stratified the analyses based on histological subtypes, stage, and diagnostic process via cancer screening. The increase in the overall age-standardized incidence was not significant. However, the increase was significant for women aged 30–39 years (AAPC 20.0%/year, 95% CI: 9.9–31.1), which was attributable to the increase in the incidence of the squamous cell carcinoma (SCC) subtype (AAPC 23.1%/year, 95% CI: 10.7–36.8). Among younger women, aged <50 years, further stratification showed an increase in the undiagnosed early-stage SCC subtype via cancer screening. In Japan, the incidence of HPV-related cervical cancer has been increasing in undiagnosed younger women.

Abstract
BACKGROUND The prevalent location and incidence of intraductal papillary neoplasm of the bile duct (IPNB) and invasive carcinoma associated with them have varied markedly among studies due to differences in diagnostic criteria and tumor location. METHODS IPNBs were classified into two types: Type 1 IPNB, being histologically similar to intraductal papillary mucinous neoplasm of the pancreas, and Type 2 IPNB, having a more complex histological architecture with irregular papillary branching or foci of solid-tubular components. Medical data were evaluated. RESULTS Among 694 IPNB patients, 520 and 174 had Type 1 and Type 2, respectively. The levels of AST, ALT, ALP, T. Bil, and CEA were significantly higher in patients with Type 2 than in those with Type 1. Type 1 IPNB was more frequently located in the intrahepatic bile duct than Type 2, whereas Type 2 was more frequently located in the distal bile duct than Type 1 IPNB (P < 0.001). There were significant differences in 5-year cumulative survival rates (75.2% vs 50.9%; P < 0.0001) and 5-year cumulative disease-free survival rates (64.1% vs 35.3%; P < 0.0001) between the two groups. CONCLUSION Type 1 and Type 2 IPNBs differ in their clinicopathological features and prognosis. This classification may help to further understand IPNB.

Abstract
Aim To clarify the status of personal protective equipment (PPE) and coronavirus disease 2019 (COVID‐19) tests for pregnant women, we conducted an urgent survey. Methods The survey was conducted online from April 27 to May 1, 2020. Questionnaires were sent to core facilities and affiliated hospitals of the obstetrics and gynecology training program and to hospitals of the national perinatal medical liaison council. Results A total of 296 institutions participated in our survey; however, 2 institutions were excluded. Full PPE was used by doctors in 7.1% of facilities and by midwives in 6.8%. Our study also determined that around 65.0% of facilities for doctors and 73.5% of facilities for midwives used PPE beyond the “standard gown or apron, surgical mask, goggles or face shield” during labor of asymptomatic women. N95 masks were running out of stock at 6.5% of the facilities and goggles and face shields at 2.7%. Disposable N95 masks and goggles or face shields were re‐used after re‐sterilization in 12% and 14% of facilities, respectively. Polymerase chain reaction (PCR) testing of asymptomatic patients was performed for 9% of vaginal deliveries, 14% of planned cesarean sections and 17% of emergency cesarean sections. The number of PCR tests for obstetrics and gynecology per a week ranged from zero to five in 92% of facilities. Conclusion The shortage of PPE in Japan is alarming. Sufficient stockpiling of PPE is necessary to prevent unnecessary disruptions in medical care. Appropriate guidelines for PPE usage and COVID‐19 testing of pregnant women at delivery are needed in Japan.

Abstract
Aim: The association between atrial fibrillation (AF) and risk of stroke mortality among men and women without traditional cerebrocardiovascular risk factors (TCVRFs) is unclear. This study aimed to determine whether AF was a risk factor for stroke and total cardiovascular disease mortality among individuals without TCVRFs. Methods: A total of 90,629 Japanese subjects from the Ibaraki Prefectural Health Study aged 40–79 years, with and without TCVRFs, were studied from 1993 to 2013. Hazard ratios (HRs) were calculated using the Cox proportional hazard regression model stratified by sex and the presence of TCVRFs. Covariates were age, systolic blood pressure, anti-hypertensive medication use, and serum total cholesterol levels. A standard 12-lead electrocardiogram at rest was used to screen AF. Cause-specific mortality was classified according to the International Classification of Disease code. Results: Compared with participants without AF, multivariable-adjusted hazard ratios (with 95% confidence intervals) for stroke mortality among participants without TCVRFs were 4.3 (1.1–17.8) and 15.0 (5.5–40.8) for men and women with AF, respectively. HRs for total cardiovascular disease mortality were 6.2 (2.8–14.2) for men and 10.7 (4.8–24.1) for women. For participants with TCVRFs, multivariable-adjusted HRs for stroke mortality were 3.1 (2.2–4.6) and 4.3 (2.6–7.3), whereas HRs for total cardiovascular disease mortality were 2.9 (2.2–3.8) and 3.5 (2.4–5.1) for men and women, respectively. Conclusions: AF was found to be an independent risk factor for stroke and total cardiovascular mortality even in individuals without other TCVRFs.

[PMID: 32517151 PMCID: PMC7312590 DOI: 10.3390/ijerph17114052] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 05/29/2020] [Accepted: 06/01/2020] [Indexed: 01/07/2023]
Abstract
The association of gestational hypertension (GH) with future hypertension in Japanese women is unclear. Hence, this study aimed to examine the association between GH and the risk of future hypertension in middle-aged-to-older Japanese women. A case-control study was performed, including 62 hypertensive women (case) and 75 nonhypertensive women (control). GH during the first pregnancy was diagnosed on the basis of the Maternal and Child Health Handbook record. Hypertensive women were recruited from outpatients in the hospital and residents who completed an annual health check-up in a community. Hypertension was defined as blood pressure with systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, or taking antihypertensive medications. The average age (SD) of the cases and controls at the time of recruitment was 63.1 (8.4) and 57.7 (9.4), respectively. The multivariable-adjusted odds ratio of GH for hypertension in middle-aged-to-older women was 4.2 (95% confidence interval, 1.0–17.5) after adjustment for potential confounding factors such as age and body-mass index (BMI) upon recruitment, prepregnancy BMI, and age at first delivery. In conclusion, GH can be an independent risk factor for future hypertension among Japanese women.

Incidence of Metabolic Syndrome in Young Japanese Adults in a 6-Year Cohort Study: The Uguisudani Preventive Health Large-Scale Cohort Study (UPHLS). J Epidemiol 2020; 30:219-226. [PMID: 31080190 PMCID: PMC7153962 DOI: 10.2188/jea.je20180246] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Accepted: 04/15/2019] [Indexed: 01/05/2023] Open
Abstract
INTRODUCTION To clarify the incidences of metabolic syndrome (MS) and risks in young Japanese adults by gender. METHODS A total of 58,901 adults who had undergone annual health check-ups in 2010 without a diagnosis of MS or missing data were divided into three age groups (20s through 40s) by gender. Participants were followed up for 6 years for new-onset MS according to Japanese criteria. The incidences of MS and risks were analyzed using the Cox proportional hazards model to adjust for confounding factors. RESULTS The incidences of MS per 1,000 person-years were 2.2, 5.5, and 10.2 for women aged in their 20s, 30s, and 40s, respectively, and 26.3, 40.5, and 57.4 in the respective men groups. Compared with the group aged in their 40s, the hazard ratios of new MS were 0.19 (95% confidence interval [CI], 0.13-0.29) for women in their 20s and 0.50 (95% CI, 0.41-0.61) for women in their 30s, and 0.46 (95% CI, 0.42-0.50) and 0.70 (95% CI, 0.66-0.73) for men in their 20s and 30s, respectively, after adjustment for lifestyle factors. For women, MS was associated with smoking in their 20s and 30s, and eating speed in their 30s, and for men, was associated with physical activity, eating speed, alcohol intake in their 20s and 30s, and smoking in their 30s. CONCLUSION Our findings suggest that the incidences of MS in the 20s and 30s are lower, but account for about 20-50% of women with MS and 50-70% of men with MS in their 40s. However, the data are not negligible and early lifestyle intervention for MS is necessary in young adults.

Urinary 8-Hydroxy-2'-Deoxyguanosine Levels and Cardiovascular Disease Incidence in Japan. J Atheroscler Thromb 2020; 27:1086-1096. [PMID: 32161250 PMCID: PMC7585906 DOI: 10.5551/jat.51664] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/11/2023] Open
Abstract
Aim: The association between urinary 8-hydroxy-2′-deoxyguanosine (8-OHdG), an oxidative stress marker, and the incidence of cardiovascular disease (CVD) has not been confirmed because no previous studies evaluated 24-hour 8-OHdG excretion levels in the general population. We aimed to confirm the association between 24-hour urinary 8-OHdG levels and CVD risk among Japanese men and women. Methods: A nested case-control study was performed based on a 24-hour urine collection in a community-based cohort study performed from 1996 to 2005. Seventy-six cases (55 men and 21 women) who experienced their first CVD incidence during the follow-up period (median: 5.9 years) were recruited. The controls were frequency-matched 1:2, with each case for sex, age, area of residence, and baseline year. The 8-OHdG level was measured by enzyme-linked immunosorbent assay. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using conditional logistic regression models adjusted for body mass index, ethanol intake, smoking status, and estimated glomerular filtration rate. Results: The geometric mean and geometric standard deviation (SD) of 8-OHdG levels (nmol/day) for cases and controls were 35.5 (1.55) and 35.5 (1.54) for men and 32.1 (1.35) and 25.0 (1.39) for women, respectively. The multivariable OR (95% CI) of CVD incidence according to the 1-SD increment of the log-transformed 8-OHdG level was 2.08 (0.99–4.37) for women. The multivariable ORs (95% CIs) for the 1st (lowest) and 4th versus 2nd quartile according to 8-OHdG for men were 3.29 (1.02–10.61) and 2.77 (0.96–7.96), respectively. Conclusion: A high 8-OHdG level tended to be associated with CVD incidence among women.

Abstract
OBJECTIVES Hearing impairment is among the most significant health problems, and the number of adults with hearing impairment is increasing worldwide. Therefore, the prevention of hearing impairment is important. Proteinuria appears to be a risk factor for hearing impairment, but no prospective studies have examined the association between proteinuria and hearing impairment risk. This prospective study aimed to clarify the association between dipstick proteinuria and risk of hearing impairment. DESIGN This was a prospective cohort study based on annual health check-up data, 2008-2016. SETTING Data were collected on 7005 employees of a single company who worked in offices and factories throughout Japan. PARTICIPANTS We analysed data from 5699 subjects (88.6% men) who underwent annual health check-ups twice or more from 2008 to 2016, had no missing data, and were free from hearing impairment at baseline. We regarded the first health check-up as the baseline examination. PRIMARY AND SECONDARY OUTCOME MEASURES Hearing tests were performed using audiometry at two frequencies (1 and 4 kHz) during the health check-ups. Defining total moderate hearing impairment as the inability to respond to 30 dB at 1 kHz and/or 40 dB at 4 kHz, we examined the association between dipstick proteinuria at baseline and risk of hearing impairment at final examination. RESULTS Total moderate hearing impairment was noted in 162 (2.8%) subjects. Compared with subjects without proteinuria at baseline, the multivariable adjusted OR (95% CI) was 5.35 (1.87-15.25) for subjects with proteinuria ≥2+, 0.92 (0.40-2.13) for those with proteinuria +/-, and 1.33 (0.63-2.80) for those with proteinuria+ at baseline. CONCLUSIONS Severe dipstick proteinuria was positively associated with risk of hearing impairment in the future. Our results suggest that medical examinations including urine testing are effective for detecting subjects with high risk of hearing impairment.

Age-Specific Impact of Atrial Fibrillation on Cardiovascular Mortality Among Japanese Men and Women (The Ibaraki Prefectural Health Study [IPHS]). Am J Cardiol 2019; 124:1413-1419. [PMID: 31481178 DOI: 10.1016/j.amjcard.2019.07.047] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2019] [Revised: 07/18/2019] [Accepted: 07/22/2019] [Indexed: 11/16/2022]
Abstract
The age-specific impact of atrial fibrillation (AF) on cardiovascular diseases remains unclear. A total of 90,629 participants who were from 40 to 79 years of age in 1993 were followed up until 2013 as part of the Ibaraki Prefectural Health Study. Hazard ratios for mortality stratified by gender and age groups were calculated using Cox's proportional hazards regression models. A total of 22,794 patients (11,329 men and 11,465 women) died during the follow-up period, including 6,684 patients who died of cardiovascular causes (2,951 men and 3,733 women). On multivariable analysis, participants with AF had an increased risk of cardiovascular-related mortality compared with those without AF. Among participants aged 40 to 64 years, the adjusted hazard ratios were 3.2 (95% confidence interval [CI] 2.0 to 5.3) for men and 7.1 (95% CI 3.2 to 16.0) for women; the corresponding adjusted hazard ratios among participants aged 65 to 79 years were 3.0 (95% CI 2.2 to 4.0) for men and 3.7 (95% CI 2.5 to 5.4) for women. No significant difference in hazard ratios between age groups was found for either gender. AF was significantly associated with all-cause mortality in each age and gender group; again, no significant difference in hazard ratios between the age groups was found in terms of AF. AF may be an independent risk factor for cardiovascular and all-cause mortalities regardless of age.
