RESUMEN
INTRODUCTION: Evidence for the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) between a basket catheter and a balloon catheter for endoscopic common bile duct stone (CBDS) removal is lacking. This study aimed to compare ERCP outcomes using a basket catheter and a balloon catheter for endoscopic CBDS removal. METHODS: This multicenter retrospective study included 904 consecutive patients with native papilla who underwent endoscopic stone removal for CBDS ≤10 mm using a basket catheter and/or a balloon catheter at three institutions in Japan. ERCP outcomes between the basket and balloon groups were compared using inverse probability of treatment weighting (IPTW) method. RESULTS: ERCP-related adverse events occurred in 6.5% (29/449) and 7.7% (35/455) of patients in the basket and balloon groups, respectively (IPTW-adjusted p = 0.52). The incidences of post-ERCP pancreatitis, cholangitis, and perforation were similar in the basket and balloon groups (3.8% vs. 2.9%, 1.3% vs. 0.9%, and 0.7% vs. 0.7%, respectively). However, bleeding incidences were significantly higher in the balloon group than in the basket group (3.3% vs. 0.7%, IPTW-adjusted p = 0.012). Successful complete stone removal at one ERCP session using a single catheter was achieved in 17.8% (80/449) in the basket group and in 81.3% (370/455) in the balloon group (IPTW-adjusted p < 0.001). DISCUSSION: A balloon catheter is more likely to complete stone extraction for CBDS ≤10 mm with a single catheter at one endoscopic stone removal session. However, the risk for post-ERCP bleeding is higher in the balloon group than in the basket group.

INTRODUCTION: The objective of this study is to evaluate the epidemiological characteristics of Japanese Spotted Fever (JSF) cases reported through the National Epidemiological Surveillance of Infectious Disease (NESID) system in Shimane Prefecture, Japan, from 2000 to 2022, encompassing the periods before and during the COVID-19 pandemic period. METHODS: A retrospective analysis was conducted on JSF cases reported to the NESID system in Shimane Prefecture between 2000 and 2022. Population data were obtained from the Statistical Information of Shimane. Poisson regression analysis was employed to examine the relationship between the annual prevalence rate of JSF and the COVID-19 pandemic. RESULTS: A total of 301 JSF cases were analyzed during the study period. Even the pre-COVID-19 pandemic period, a gradual and significant increase in the prevalence rate was observed (prevalence rate = 1.03, 95% CI: 1.01-1.05; p = 0.01), and a rapid increase was noted since 2020 (prevalence rate = 1.57, 95% CI: 1.39-1.78; p < 0.01). The slope during the pre-COVID-19 pandemic period was estimated to have significantly increased (p < 0.01). CONCLUSIONS: Our findings suggest that while the prevalence rate of JSF had exhibited a slight increase in the years preceding the COVID-19 pandemic, it demonstrated a more significant increase following the pandemic in Shimane Prefecture. JSF has increased since 2020 and may be linked to COVID-19 pandemic. The COVID-19 pandemic has had a substantial impact on global health, underscoring the importance of investigating the prevalence of specific infectious diseases and other health-related indicators to accurately assess the pandemic's impact.

BACKGROUND: It remains unclear which comorbidities, other than lipid parameters, or combination of comorbidities, best predicts cardiovascular events in patients with known coronary artery disease (CAD) treated with statins. Therefore, we aimed to identify the nonlipid-related prognostic factors and risk stratification of patients with stable CAD enrolled in the REAL-CAD study.MethodsâandâResults: Blood pressure, glucose level, and renal function were considered as risk factors in the 11,141 enrolled patients. The primary endpoint was a composite of cardiovascular death, nonfatal myocardial infarction, nonfatal ischemic stroke, and unstable angina. The secondary composite endpoint was the primary endpoint and/or coronary revascularization. A significantly worse prognosis at the primary endpoint was observed in the estimated glomerular filtration rate (eGFR) ≤60 group, and the combination of eGFR ≤60 and HbA1c ≥6.0 was the worst (hazard ratio (HR) 1.66; P<0.001). However, even in the eGFR >60 group, systolic blood pressure (SBP) ≥140 mmHg met the secondary endpoint (HR 1.33; P=0.006), and the combination of eGFR ≤60 and HbA1c ≥6.0 was also the worst at the secondary endpoint (HR 1.35; P=0.002). CONCLUSIONS: Regarding nonlipid prognostic factors contributing to the incidence of cardiovascular events in statin-treated CAD patients, renal dysfunction was the most significant, followed by poor glucose control and high SBP.
RESUMEN
BACKGROUND: Unnecessary endoscopic retrograde cholangiopancreatography (ERCP) after spontaneous passage of common bile duct stones (CBDSs) should be avoided. This study aimed to examine the cumulative diagnosis rate and the predictive factors of spontaneous CBDS passage during the interval between the imaging diagnosis and ERCP. METHODS: This multicenter retrospective study included 1260 consecutive patients with native papilla diagnosed with CBDSs using imaging modalities. Predictive factors and cumulative diagnosis rate of spontaneously passed CBDSs during the interval between imaging diagnosis and ERCP were analyzed. RESULTS: The overall cumulative diagnosis rate of spontaneous CBDS passage was 6.2% (78/1260) during a mean interval of 5.0 days. In the multivariate analysis, CBDS sized < 6 mm on diagnostic imaging, solitary CBDS on diagnostic imaging, intervals between the imaging diagnosis and ERCP, and nondilated common bile duct (< 10 mm) were the significant factors associated with spontaneous CBDS passage. Specifically, the cumulative diagnosis rate of spontaneous passage was significantly higher in patients with solitary and CBDSs sized < 6 mm than in those with other CBDSs (14.4% [54/376] vs. 2.7% [24/884], P < 0.001). In both the asymptomatic and symptomatic groups, the cumulative diagnosis rate of the spontaneous passage of CBDSs was significantly higher in patients with solitary and CBDSs sized < 6 mm on diagnostic imaging than in those with multiple and/or CBDSs sized ≥ 6 mm on diagnostic imaging during a mean interval of 20.5 and 2.4 days, respectively (asymptomatic group: 22.4% [15/67] vs. 3.5% [4/113], P < 0.001, symptomatic group: 12.6% [39/309] vs. 2.6% [20/771], P < 0.001). CONCLUSIONS: Solitary and CBDSs sized < 6 mm on diagnostic imaging can often lead unnecessary ERCP due to spontaneous passage. Preliminary endoscopic ultrasonography immediately before ERCP is recommended, especially in patients with solitary and small CBDSs on diagnostic imaging.

BACKGROUND: The revised American Society for Gastrointestinal Endoscopy (ASGE) guideline 2019 provides the high-risk criteria for suspected common bile duct stones (CBDSs). AIMS: To evaluate CBDS detection rates during endoscopic retrograde cholangiopancreatography (ERCP) in high-risk patients with suspected CBDSs based on the ASGE guideline 2019. METHODS: This multicenter retrospective study included 1100 consecutive patients who underwent ERCP for suspected CBDSs with any high-risk criteria based on the revised ASGE guideline 2019: Criterion 1, CBDSs on imaging; Criterion 2, clinical ascending cholangitis; and Criterion 3, total bilirubin exceeding 4 mg/dL and dilated common bile duct on imaging. We compared CBDS detection rates during ERCP based on individual and combined high-risk criteria. RESULTS: The CBDS detection rates of patients who met any of the criteria, only Criterion 1, and Criteria 2 or 3 were 86.0% (946/1100), 93.4% (113/121), and 50.0% (106/212), respectively. In patients who met Criteria 1 and 2, 1 and 3, 2 and 3, and all criteria, CBDSs were confirmed during ERCP in 95.1% (490/515), 96.2% (25/26), 55.3% (26/47), and 98.4% (186/189), respectively. The CBDS detection rate during ERCP of patients with at least Criterion 1 significantly exceeded that of patients without at least Criterion 1 [95.7% (814/851) vs. 51.0% (132/259), respectively, P < 0.001]. CONCLUSIONS: Patients with CBDS visualization on imaging have very high CBDS detection rates during ERCP. However, performing ERCP on patients with only clinical predictors, such as cholangitis and dilated CBD with total bilirubin exceeding 4 mg/dL, often results in unnecessary ERCP.

As the prognosis of cancer patients has been improved, comorbidity of heart failure (HF) in cancer survivors is a serious concern, especially in the aged population. This study aimed to examine the risk factors of HF development after treatment by anticancer agents, using a machine learning-based analysis of a massive dataset obtained from the electronic health record (EHR) in Japan. This retrospective, cohort study, using a dataset from 2008 to 2017 in the Diagnosis Procedure Combination (DPC) database in Japan, enrolled 140,327 patients. The structure of risk factors was determined using multivariable analysis and classification and regression tree (CART) algorithm for time-to-event data. The mean follow-up period was 1.55 years. The prevalence of HF after anticancer agent administration were 4.0%. HF was more prevalent in the older than the younger. As the presence of cardiovascular diseases and various risk factors predicted HF, CART analysis of the risk factors revealed that the risk factor structures complicatedly differed among different age groups. The highest risk combination was hypertension, diabetes mellitus, and atrial fibrillation in the group aged ≤ 64 years, and the presence of ischemic heart disease was a key in both groups aged 65-74 years and 75 ≤ years. The machine learning-based approach was able to develop complicated HF risk structures in cancer patients after anticancer agents in different age population, of which knowledge would be essential for realizing precision medicine to improve the prognosis of cancer patients.

AIM: To determine the gestational age-related changes in cervical gland length in relation to cervical length (CL) in normal singleton pregnancies. METHODS: We studied 363 women with an uncomplicated singleton pregnancy (188 nulliparous and 175 multiparous women with one or more previous transvaginal deliveries). A total of 1138 cervical gland and CLs were measured longitudinally at 17-36 weeks of gestation using transvaginal ultrasonography along the curvature from the external os to the lower uterine segment and the internal end of the cervical gland area (CGA), respectively. Gestational age-related changes in cervical gland and CLs and their relationships were analyzed using a linear mixed model. RESULTS: Cervical gland and CLs decreased in different ways with advancing gestation depending on parity, and their changes were related to each other. The CGAs in nulliparous women were longer than those in multiparous women at 17-25 weeks of gestation (p < 0.05), but with no differences thereafter. CLs in multiparous women were different from those in nulliparous women at 17-23 and 35-36 weeks (p < 0.05), but there were no differences at 24-34 weeks. The cervix did not shorten compared with the CGA throughout the observational periods in nulliparous and multiparous women. CONCLUSIONS: Shortening of the cervix indicates changes to the lower uterine segment in normal pregnancies. The cervical gland region can be a useful marker representing the true cervix beyond 25 weeks of gestation, irrespective of parity.

BACKGROUND: The Japanese Society for Spine Surgery and Related Research previously developed a diagnostic support tool for lumbar spinal stenosis (LSS-DST). Using the LSS-DST, general physicians can identify potential cases of LSS. However, in the LSS-DST, measurement of the ankle brachial pressure index (ABI) is required to exclude peripheral artery lesions in the lower limbs. We can expect further application of the LSS-DST if we can identify a simpler and easier method than ABI measurement. Therefore, in this large-scale, multicenter, cross-sectional study, we verified whether palpation of the posterior tibial (PT) artery could be used instead of ABI in the LSS-DST. METHODS: This survey was conducted at 2177 hospitals and included 28,883 participants. The sensitivity and specificity of the original LSS-DST method using the ABI and that of the LSS-DST ver2.0 with PT artery palpation were assessed to screen their ability for diagnosing LSS, using the physicians' final diagnosis based on the patients' history, physical examination and radiographic findings as the gold standard. RESULTS: The sensitivity and specificity [95%CI] of the LSS-DST were 88.2% [87.5, 88.8] and 83.9% [83.4, 84.5], respectively, whereas the sensitivity and specificity of the LSS-DST ver2.0 were 87.7% [87.0, 88.3] and 78.3% [77.7, 78.9], respectively, indicating that LSS-DST ver2.0 is a useful screening tool for LSS with good sensitivity. CONCLUSION: When the item of ABI in the LSS-DST is replaced by palpation of the PT artery (LSS-DST ver2.0), its sensitivity is maintained as a screening tool for LSS. LEVEL OF EVIDENCE: Level 3.

BACKGROUND: Mild cognitive impairment (MCI) individuals also show significant parasympathetic deficits, while autonomic nervous system (ANS) flexibility can strengthen cognitive and brain function. Paced (or slow) breathing has significant effects on the ANS and is associated with relaxation and well-being. However, paced breathing requires considerable time and practice, a significant barrier to its widespread adoption. Feedback systems appear promising to make practice more time-efficient. A tablet guidance system providing real-time feedback on autonomic function was developed for MCI individuals and tested for efficacy. METHODS: In this single-blind study, 14 outpatients with MCI practised with the device for 5 min twice a day for 2 weeks. The active group received feedback (FB+), whereas the placebo group (FB-) did not. Coefficient of variation of R-R intervals as the outcome indicator was measured immediately after the first intervention (T1 ), the end of the 2-week intervention (T2 ), and 2 weeks later (T3 ). RESULTS: The mean outcome of the FB- group remained unchanged during the study period, whereas the outcome value of the FB+ group increased and retained the intervention effect for an additional 2 weeks. CONCLUSIONS: Results indicate this FB system-integrated apparatus may be useful for MCI patients for effectively learning paced breathing.

AIM: The aim of this study was to investigate initial symptoms of early-onset dementia (EOD) for each dementia subtype. METHOD: We conducted a nationwide, population-based EOD prevalence study in Japan. Data were collected through service providers for people with EOD. Initial symptoms were assessed in six domains: loss of memory, difficulty in word generation, irritability, loss of motivation, increased mistakes in the workplace or domestically, and unusual behaviours or attitudes other than those listed. RESULTS: Participants were 770 people with EOD. Characteristic initial symptoms were observed for each EOD subtype. Loss of memory was more common in early-onset Alzheimer's disease (75.7%, P < 0.001), difficulty in word generation was more common in early-onset vascular dementia (41.3%, P < 0.001), and loss of motivation, increased mistakes in the workplace or domestically, and unusual behaviours or attitudes other than those listed were more common in early-onset frontotemporal dementia (34.9%, P < 0.001; 49.4%, P < 0.001; 34.9%, P < 0.001, respectively). In addition, we observed gender differences whereby loss of memory was more common among women and irritability was more common among men. More than half of the participants were employed at symptom onset, and 57.2% of those who were employed at the onset had initial symptoms of increased mistakes in the workplace or domestically. CONCLUSION: This report reveals differences in the frequency of initial symptoms by EOD subtype. The results contribute to increasing public awareness of the initial symptoms of EOD, which will facilitate early diagnosis and social support.

Patients with urea cycle disorders intermittently develop episodes of decompensation with hyperammonemia. Although such an episode is often associated with starvation and catabolism, its molecular basis is not fully understood. First, we attempted to elucidate the mechanism of such starvation-associated hyperammonemia. Using a mouse embryonic fibroblast (MEF) culture system, we found that glucose starvation increases ammonia production, and that this increase is associated with enhanced glutaminolysis. These results led us to focus on α-ketoglutarate (AKG), a glutamate dehydrogenase inhibitor, and a major anaplerotic metabolite. Hence, we sought to determine the effect of dimethyl α-ketoglutarate (DKG), a cell-permeable AKG analog, on MEFs and found that DKG mitigates ammonia production primarily by reducing flux through glutamate dehydrogenase. We also verified that DKG reduces ammonia in an NH4 Cl-challenged hyperammonemia mouse model and observed that DKG administration reduces plasma ammonia concentration to 22.8% of the mean value for control mice that received only NH4 Cl. In addition, we detected increases in ornithine concentration and in the ratio of ornithine to arginine following DKG treatment. We subsequently administered DKG intravenously to a newborn pig with hyperammonemia due to ornithine transcarbamylase deficiency and found that blood ammonia concentration declined significantly over time. We determined that this effect is associated with facilitated reductive amination and glutamine synthesis. Our present data indicate that energy starvation triggers hyperammonemia through enhanced glutaminolysis and that DKG reduces ammonia accumulation via pleiotropic mechanisms both in vitro and in vivo. Thus, cell-permeable forms of AKG are feasible candidates for a novel hyperammonemia treatment.

BACKGROUND: The localization of myocardial 18F-fluorodeoxyglucose (FDG) uptake affecting long-term clinical outcomes has not been elucidated in patients with corticosteroid-naïve cardiac sarcoidosis (CS). OBJECTIVES: This study sought to investigate the localization of myocardial FDG uptake on positron emission tomography (PET) and myocardial perfusion abnormality to predict adverse events (AEs) for a long-term follow-up in patients with corticosteroid-naïve CS. METHODS: Consecutive 90 patients with clinical suspicion of CS who underwent FDG-PET imaging to assess for inflammation were enrolled. AEs were defined as a composite of sustained ventricular tachycardia (VT), heart transplantation, and all-cause death, which were ascertained by medical records, defibrillator interrogation, and telephone interviews. RESULTS: Of 90 patients, 42 patients (mean age 62.9 ± 12.0 years; 76.2% females) were confirmed active cardiac involvement. Over a median follow-up of 4.9 years, 15 patients with CS experienced AEs including 6 sustained ventricular tachycardias (VT) and 9 deaths. Cox proportional-hazards model after adjustment for left ventricular systolic dysfunction revealed that FDG uptake in the right ventricle (RV) or basal anterolateral area of the left ventricle (LV) with myocardial perfusion abnormality was predictive of AEs. CONCLUSIONS: FDG uptake in the RV or basal anterolateral area of the LV with myocardial perfusion abnormality provides long-term prognostic risk stratification in patients with corticosteroid-naïve CS.

BACKGROUND: Laminin receptor is a non-integrin cell-surface receptor that binds laminin present on the basement membrane. It has been reported to be associated with infiltration and metastasis of various malignant tumors. However, no studies regarding tongue cancer have been reported. This study aimed to clarify the role of laminin receptor in squamous cell carcinoma of the tongue. METHODS: We performed immunohistochemical staining of specimens from 66 patients with squamous cell carcinoma of the tongue and assessed laminin receptor expression and clinicopathological factors. As epithelial-mesenchymal transition has been shown to be associated with infiltration and metastasis of malignant tumors, staining for E-cadherin, vimentin, and N-cadherin were also performed. RESULTS: Of 20 patients with postoperative recurrence, 14 exhibited high laminin receptor expression (p = 0.0025). Kaplan-Meier analysis revealed a significantly shorter time to postoperative recurrence for the high laminin receptor expression group than that for the low laminin receptor expression group (p = 0.0008). Based on multivariate analyses for postoperative recurrence, high laminin receptor expression was associated with poor prognosis (high expression vs. low expression; HR =3.19, 95% CI =0.92-11.08; p = 0.0682). There was a correlation between laminin receptor and N-cadherin (p = 0.0089) but not between laminin receptor and E-cadherin (p = 0.369) or vimentin (p = 0.4221). CONCLUSION: These results suggest that high laminin receptor expression is a useful prognostic factor for postoperative recurrence and may be a target for molecular therapy to treat squamous cell carcinoma of the tongue.

BACKGROUND AND AIM: Choledocholithiasis is the most common indication for endoscopic retrograde cholangiopancreatography (ERCP). Identifying risk factors for post-ERCP pancreatitis (PEP) is important for reducing the risk of developing PEP after common bile duct (CBD) stone removal. However, studies examining the risk factors for PEP for CBD stones are scarce. The aim of this study was to examine whether the presence or absence of acute cholangitis is a clinical risk factor for PEP in patients with CBD stones. METHODS: In this multicenter retrospective study, 1539 patients with naïve papillae were divided into patients without and with acute cholangitis. We compared the incidence of PEP between the two groups using one-to-one propensity score matching to adjust for the potential confounding factors of PEP. RESULTS: In the entire cohort, the rates of PEP in patients without and with acute cholangitis were 9.6% (52/542) and 1.8% (18/997), respectively (P < 0.001, odds ratio = 5.8). In the propensity-matched cohort, the rates of PEP in patients without and with acute cholangitis were 8.3% (27/326) and 2.5% (8/326), respectively (P = 0.002, odds ratio = 3.6). The rate of PEP was significantly higher in patients without acute cholangitis than in those with acute cholangitis after adjusting for the confounding factors of PEP. CONCLUSIONS: The absence of acute cholangitis may be an important clinical risk factor for PEP due to CBD stone removal. In patients without acute cholangitis, endoscopists should explain the specific risk of PEP carefully and actively implement prophylaxis against PEP.

Several studies have reported a high prevalence of missed and delayed mild cognitive impairment (MCI) or mild dementia diagnosis, which could lead to delayed treatment and increased patient and caregiver burden. OBJECTIVES: This study aimed to develop a new questionnaire for nonprofessionals to help detect early signs of MCI and dementia. Respondents included patients, family caregivers, or health professionals. Scores are calculated based on the respondent type and age of subject. METHODS: This study consisted of four steps and included 461 respondents. Steps 1-3 were conducted by a working group, and step 4, by 67 specialist members of the Japanese Society of Geriatric Psychiatry. A scoring algorithm was created and predictive diagnostic probability was analyzed using misdiscrimination rate and cross-validation after item selection to establish a cut-off value for MCI or dementia symptoms. Alzheimer's disease, Lewy body dementia, and frontotemporal dementia were diagnosed. RESULTS: The prediction error rate for patient or informant respondents was confirmed from the evaluation results of 13 items. Sensitivity and specificity were 90.6% and 56.6%, respectively, with a cut-off score of 2. Overall, 82% (61 pairs) of respondents received a definitive diagnosis following a diagnosis from the questionnaire. CONCLUSIONS: This questionnaire could promote earlier presentation to clinical settings for treatment. The high sensitivity indicates the utility of this instrument, but it is not meant as a definitive diagnostic tool and should be followed with a professional assessment.

BACKGROUND: Risk stratification of postendoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) for common bile duct (CBD) stones is needed for clinicians to adequately explain to patients regarding the risk of PEP in advance of ERCP and to proactively take preventive measures in high-risk patients. AIMS: To stratify the risk of PEP for CBD stones based on CBD-related diseases. METHODS: A total of 1551 patients with naïve papilla who underwent ERCP for CBD stones were divided into three groups: Group A: asymptomatic CBD stones, Group B: obstructive jaundice and elevated liver test values without cholangitis, and Group C: mild, moderate, and severe cholangitis. We stratified the risk of PEP by comparing its incidence among the three groups using the Holm's method. Furthermore, we performed one-to-one propensity score matching between Group A and the other groups to examine the risk of PEP in Group A. RESULTS: The incidence rates in Groups A, B, and C were 13.7%, 7.3%, and 1.8%, respectively. The Holm-adjusted p values between Groups A and B, Groups A and C, and Groups B and C were 0.023, < 0.001, and < 0.001, respectively. Propensity score matching revealed that the incidence of PEP was significantly more in Group A than in the other groups (13.3% vs. 1.5%; p < 0.001). CONCLUSIONS: The risk of PEP for CBD stones was stratified into low risk (Group C), intermediate risk (Group B), and high risk (Group A). This simple disease-based risk stratification may be useful to predict the risk of PEP in advance of ERCP.

BACKGROUND: Reports of zinc and selenium deficiencies accompanying inflammatory bowel disease (IBD) mostly have originated from Western countries and concerned adult patients. Whether Japanese children with IBD have similar deficiencies remained unclear. AIM: We aimed to elucidate differences in serum zinc and selenium concentrations in Japanese children between types of IBD. METHODS: Children under 17 years old undergoing care at 12 Japanese pediatric centers were retrospectively enrolled between November 2016 and February 2018 to 3 groups representing Crohn's disease (CD), ulcerative colitis (UC), and normal controls (NC) with irritable bowel syndrome or no illnesses. Serum zinc and selenium were measured by atomic absorption spectrophotometry. Zinc and selenium deficiencies were defined by serum concentrations < 70 µg/dL and < 9.5 µg/dL, respectively. RESULTS: Subjects included 98 patients with CD (median age, 13 years), 118 with UC (11 years), and 43 NC (11 years). Serum zinc and selenium were significantly lower in CD (median, 64 and 12.6 µg/dL respectively) than in UC (69 and 14.6; P < 0.05 and P < 0.001) or NC (77 and 15.7; P < 0.01 and P < 0.001). Zinc deficiency was significantly more prevalent in CD (60.2%) than in NC (37.2%; P < 0.05), but not than in UC (51.7%; P = 0.22). Selenium deficiency was significantly more prevalent in CD (15.3%) than in UC (5.9%; P < 0.05) or NC (0%; P < 0.01). CONCLUSIONS: In Japanese children under 17 years old, serum zinc and selenium were significantly lower in CD than in UC or NC. Zinc and selenium should be monitored, and supplemented when deficient, in children with IBD, especially CD.

INTRODUCTION: Despite the growing population of long-term survivors with human immunodeficiency virus 1 (HIV) exhibiting asthma-like features worldwide, the pathogenesis underlying airway hyperresponsiveness (AHR) and airway inflammation remains unclear. We aimed to investigate AHR and airway inflammation in an HIV-infected Japanese population. METHODS: Of 94 Japanese participants, 10 HIV-infected participants with asthma were excluded from the study. We compared the characteristics of HIV-infected (n = 34) and non-HIV-infected participants (n = 50). Eosinophilic, neutrophilic, mixed (eosinophilic and neutrophilic), and paucigranulocytic airway inflammatory phenotypes were classified based on induced sputum characteristics. RESULTS: The prevalence of AHR in HIV-infected participants (32.4%) was significantly higher than that in their non-HIV-infected counterparts (10.0%) (P = 0.0213). The multivariate nominal logistic regression analysis revealed HIV as an independent risk factor for AHR. HIV-infected participants were significantly more likely to have a neutrophilic airway inflammatory phenotype than non-HIV-infected participants (P = 0.0358). Furthermore, HIV-infected participants with AHR demonstrated a significant correlation between AHR levels and the percentage of sputum neutrophils (r = -0.65, P = 0.0316). The percentage of sputum neutrophils was negatively associated with the blood CD4 cell count (r = -0.66, P = 0.0266). CONCLUSIONS: We observed the high prevalence of AHR and neutrophilic airway inflammatory phenotype in Japanese participants with stable HIV infection. Our findings provide insight into the mechanisms of AHR and may facilitate the development of novel treatment for individuals with AHR and HIV infection.

BACKGROUND AND AIM: Serologic markers such as myeloperoxidase (MPO) antineutrophil cytoplasmic antibodies (ANCA) (MPO-ANCA) have been used to screen patients for ulcerative colitis (UC). However, MPO-ANCA shows limited accuracy in Asians. Proteinase 3 ANCA (PR3-ANCA) has performed better at UC diagnosis in Japanese adults than MPO-ANCA. The present study aimed to evaluate usefulness of PR3-ANCA for diagnosis of UC in Japanese pediatric practice. METHODS: Patients under 17 years old undergoing assessment at 12 Japanese pediatric centers between November 2016 and February 2018 were prospectively enrolled and divided into groups with UC, Crohn's disease (CD), intestinal disease control (IC), and healthy control (HC). Serum PR3-ANCA and MPO-ANCA were analyzed using chemiluminescence enzyme immunoassay kits. RESULTS: Sera from 367 patients (148 with UC at a median age of 12 years; 120 with CD, 13 years; 56 with IC, 10.5 years; and 43 with HC, 10 years) were examined. Median PR3-ANCA values in UC (1.6 U/mL) were greater than in CD (0.2; P < 0.001), IC (0.15; P < 0.001), and HC (0.1; P < 0.001). In receiver operating characteristic curve analyses, the area under the curve for PR3-ANCA was 0.79, significantly greater than for MPO-ANCA (0.58; P < 0.001). Using a cut-off value of 0.8 U/mL determined from the receiver operating characteristic analyses, PR3-ANCA showed significantly greater sensitivity (64.9%) than MPO-ANCA (cut-off, 0.2 U/mL; sensitivity, 19.6%; P < 0.001) and good specificity (83.6%). CONCLUSIONS: In Japanese children and adolescents, PR3-ANCA performed better as a serologic marker for diagnosis of UC than MPO-ANCA. To our knowledge, this is the first report of such a comparison.

BACKGROUND: Several risk factors for postoperative retear after arthroscopic rotator cuff repair (ARCR) have been cited in a large number of reports; various combinations of these seem to be present in the clinical setting. PURPOSE: Using a combination model for decision tree analysis, we aimed to investigate the combination of risk factors that affect postoperative retear the most. METHODS: A total of 286 patients who underwent magnetic resonance (MR) imaging at 6 months after surgery were included in this study. Based on the structural integrity of the MR images taken 6 months after surgery, the patients were divided into a healed group (intact tendon, 254 patients) and a retear group (ruptured tendon, 32 patients). Using univariate and decision tree analyses, we selected a combination of 11 risk factors that drastically affected postoperative retear. RESULTS: The mean age was 64.9 ± 7.1 years, and the mean symptom duration was 9.7 ± 11.6 months. The tear was small/medium in 177 patients and large/massive in 109 patients. The technique for surgical repair was single row in 42 patients, double row in 60 patients, and suture bridging in 216 patients. On univariate analysis, both groups had significant differences in the anteroposterior (AP) tear size (P < .0001), mediolateral tear size (P < .0001), hyperlipidemia (P = .0178), global fatty degeneration index (P < .0001), supraspinatus fatty degeneration stage (P < .0001), and critical shoulder angle (CSA) (P = .0015). All of these 5 risk factors, except for mediolateral tear size, were selected as candidates for the decision tree analysis. Eight combination patterns were determined to have prediction probabilities that ranged from 4.3% to 86.1%. In particular, the combination of an AP tear size of ≥40 mm, hyperlipidemia, and a CSA of ≥37° affected retear after ARCR the most. CONCLUSIONS: Decision tree analysis lead to the extraction of different retear factor combinations, which were divided into 5 retear groups. The worst combination was of AP tear size ≥40 mm, hyperlipidemia, and CSA ≥37°, and the prediction probability of this combination was 86.2%. Therefore, our data may offer a new index for the prediction of retear after ARCR.
