A preliminary analysis of the performance of a targeted HIV electronic medical records alert system: A single hospital experience.

Early treatment of HIV relies on a timely detection of the infection, but many people living with HIV/AIDS are unaware of their infection. In the current study, we applied an electronic medical records (EMR)-based alert system flagging high-risk patients previously diagnosed with infections of syphilis, hepatitis A virus, hepatitis B virus, and/or hepatitis C virus, and those aged 20-50 years with a prior diagnosis of shingles. During the study period (April to October 2019), a total of 47 individuals among 22,264 patients visiting our department were identified as having high-risk of carrying HIV, and 14 of these individuals underwent HIV testing. Two males aged below 65 years with a previous diagnosis of syphilis were subsequently tested positive for HIV. This preliminary analysis of the EMR alert system facilitated the identification of high-risk people possibly carrying HIV, but the test rate remains to be improved.

Effects of an mHealth App (Kencom) With Integrated Functions for Healthy Lifestyles on Physical Activity Levels and Cardiovascular Risk Biomarkers: Observational Study of 12,602 Users.

BACKGROUND: Mobile health (mHealth) apps are considered to be potentially powerful tools for improving lifestyles and preventing cardiovascular disease (CVD), although only few have undergone large, well-designed epidemiological research. "kencom" is a novel mHealth app with integrated functions for healthy lifestyles such as monitoring daily health/step data, providing tailored health information, or facilitating physical activity through group-based game events. The app is linked to large-scale Japanese insurance claims databases and annual health check-up databases, thus comprising a large longitudinal cohort. OBJECTIVE: We aimed to assess the effects of kencom on physical activity levels and CVD risk factors such as obesity, hypertension, dyslipidemia, and diabetes mellitus in a large population in Japan. METHODS: Daily step count, annual health check-up data, and insurance claim data of the kencom users were integrated within the kencom system. Step analysis was conducted by comparing the 1-year average daily step count before and after kencom registration. In the CVD risk analysis, changes in CVD biomarkers following kencom registration were evaluated among the users grouped into the quintile according to their change in step count. RESULTS: A total of 12,602 kencom users were included for the step analysis and 5473 for the CVD risk analysis. The participants were generally healthy and their mean age was 44.1 (SD 10.2) years. The daily step count significantly increased following kencom registration by a mean of 510 steps/day (P<.001). In particular, participation in "Arukatsu" events held twice a year within the app was associated with a remarkable increase in step counts. In the CVD risk analysis, the users of the highest quintile in daily step change had, compared with those of the lowest quartile, a significant reduction in weight (-0.92 kg, P<.001), low-density lipoprotein cholesterol (-2.78 mg/dL, P=.004), hemoglobin A1c (HbA1c; -0.04%, P=.004), and increase in high-density lipoprotein cholesterol (+1.91 mg/dL, P<.001) after adjustment of confounders. CONCLUSIONS: The framework of kencom successfully integrated the Japanese health data from multiple data sources to generate a large, longitudinal data set. The use of the kencom app was significantly associated with enhanced physical activity, which might lead to weight loss and improvement in lipid profile.

Trajectories of kidney function and associated factors among community-dwelling older Japanese: a 16-year longitudinal study.

BACKGROUND: No study has reported trajectories of kidney function in later life. This long-term prospective study attempted to classify trajectories of estimated glomerular filtration rate (eGFR) and identify factors associated with these trajectories. METHODS: We collected data from annual geriatric health checkups conducted during 2002-2017 in Kusatsu Town, Gunma Prefecture, Japan. The participants were 1990 adults aged 65-90 years (mean [SD] age, 71.0 [5.7] years; 57.0% women), and the total number of observations was 9291. Data were analyzed with a group-based semiparametric mixture model and age-adjusted univariable cumulative logit models. RESULTS: Trajectory of kidney function, as determined by eGFR, was classified as low, middle, and high (4.8%, 38.9%, and 56.3% of men, respectively, and 5.2%, 31.5%, and 63.3% of women). Among men and women in the low trajectory group, chronic kidney disease (CKD) stage worsened from stage G3a (51.8 ml/min/1.73 m2 in men and 53.6 in women) at age 65 years to stage G4 (28.0 ml/min/1.73 m2 in men and 28.5 in women) by age 85 years. A history of hypertension (men and women) and heart disease (men) were more likely in the low trajectory group than in the middle and high trajectory groups. CONCLUSIONS: About 5% of community-dwelling older adults had an eGFR < 30 later in life. Our findings suggest that those with stage G3a CKD at age 65 years should be managed intensively, to control risk factors for CKD progression.

Pneumococcal vaccination reduces in-hospital mortality, length of stay and medical expenditure in hospitalized elderly patients.

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

The estimated impact of the 5-year national vaccination program on the trend of 23-valent pneumococcal polysaccharide vaccine vaccination rates in the elderly in Japan, 2009-2018.

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

Psychological Characteristics of Children at Two Years after the Great East Japan Earthquake: Analyses of Telephone Consultation Records.

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

Impact of the national routine vaccination program on 23-valent pneumococcal polysaccharide vaccine vaccination rates in elderly persons in Japan.

Low vaccination rates with pneumococcal vaccine in elderly persons in Japan are thought to be related to low levels of public subsidy. We previously reported that larger subsidies were significantly associated with elevated vaccination rates with the 23-valent pneumococcal vaccine (PPV23) in elderly persons. Since 2014, the Japanese government has offered subsidies through a 5-year national routine vaccination program for elderly persons at 5-year age intervals. Here, we investigated the effect of the national routine vaccination program on PPV23 vaccination rates. PPV23 vaccination rates were calculated as follows: cumulative amount shipped to each municipality divided by the population aged ≥65 years. At the end of 2015, 2 years into the 5-year national immunization program, the estimated vaccination rate was 40.6%, which was significantly increased compared with former periods (p = 0.01). Our findings show that the national routine vaccination program plays an important role in increasing the vaccination rate of PPV23 in Japan.

Body mass index and waist circumference are independent risk factors for low vital capacity among Japanese participants of a health checkup: a single-institution cross-sectional study.

OBJECTIVE: This study aimed to examine the associations between obesity and percentage vital capacity (%VC), as well as lifestyle-related disorders, among Japanese participants of a voluntary health checkup. METHODS: Subjects were 7,892 individuals who participated in a medical health checkup from January to December 2007. Multivariate logistic regression analysis was performed to assess associations between low %VC (<80) and body mass index (BMI) and waist circumference (WC), as well as lifestyle-related disorders. RESULTS: Medical histories of hypertension and dyslipidemia were more frequent in the low %VC group than in the normal %VC group in both sexes. In men, BMI was significantly associated with low %VC (25.0 ≤ C2 < 27.5, odds ratio (OR) = 2.10; 27.5 ≤ C3 < 30.0, OR = 2.23; C4 ≥ 30.0, OR = 3.46) relative to the first category (C1 < 25.0). A significant association was also observed between WC and low %VC (85 ≤ C2 < 90, OR = 1.40; 90 ≤ C3 < 95, OR = 1.55; 95 ≤ C4, OR = 2.51; relative to C1 < 85.0 cm). In women, BMI was significantly associated with low %VC in C3 and C4 (C3, OR = 2.05; C4, OR = 2.84), and WC was significantly associated with low %VC in C4 (C4, OR = 2.32). CONCLUSION: Our results suggest that obesity may be associated with restrictive pulmonary function and underscore the importance of maintaining ideal body weight for the prevention of restrictive pulmonary dysfunction.

Anti-nucleosome autoantibodies as markers for autoimmune hepatitis and their correlation with disease activity.

AIM: To assess the prevalence of autoantibodies against nucleosomes (anti-nucleosome Ab) in patients with autoimmune hepatitis (AIH), examine the correlation between anti-nucleosome Ab and disease activity, and evaluate the effectiveness of anti-nucleosome Ab in predicting relapse. METHODS: We analyzed serum anti-nucleosome Ab levels in 38 patients with AIH by enzyme-linked immunosorbent assay, and assessed their correlation with clinical characteristics. RESULTS: Anti-nucleosome Ab levels were significantly higher in AIH, but not in patients with chronic hepatitis B (n = 20) or chronic hepatitis C (n = 20), compared to healthy controls (n = 15). The positive prevalence of anti-nucleosome Ab was 71.1% in AIH. Anti-nucleosome Ab levels were significantly lower during remission compared to that during flares within the same patients with AIH. Total bilirubin levels were significantly higher in patients with anti-nucleosome Ab levels of 53.7 U/mL or more compared to those with less than 53.7 U/mL at disease onset. Analysis of the reduction in anti-nucleosome Ab by immunosuppressive therapy in 16 AIH patients revealed that age at disease onset was significantly lower and IgG levels and relapse rates were significantly higher in patients with a reduction rate of less than 35% compared to those with a reduction rate 35% or more. The International Autoimmune Hepatitis Group score and γ-globulin levels were also higher in patients with reduction rates of less than 35% (borderline significance). CONCLUSION: Anti-nucleosome Ab in AIH patients may be useful markers not only for disease diagnosis, but also for activity assessment and relapse prediction.

Association between lifestyle-related disorders and visceral fat mass in Japanese males: a hospital based cross-sectional study.

OBJECTIVE: This study aimed to examine the association between lifestyle-related disorders and visceral fat mass, and to estimate an appropriate cutoff value for visceral fat mass that correlated with body mass index (BMI) and waist circumference (WC). METHODS: This cross-sectional study was conducted between July 2012 and August 2013 at Bange Kosei General Hospital, in Fukushima, Japan. All study participants were adult males who had completed voluntary medical check-ups that included estimation of visceral fat mass by bioelectrical impedance analysis (BIA). Participants were without past histories of atherosclerotic complications or were not currently taking medications for lifestyle-related disorders. Multivariate analysis was performed to estimate the association between lifestyle-related disorders and quartiles of visceral fat mass. RESULTS: Of 536 total respondents, 442 were included in the analysis. Mean participant age was 56 years, and mean values of BMI, WC, and visceral fat mass were 24.1 kg/m(2), 85.9 cm, and 2.1 kg, respectively. Visceral fat mass ≥1.8 kg was positively associated with an increased prevalence of dyslipidemia, elevated blood pressure, and impaired glucose tolerance. Cutoff values that correlated with visceral fat mass (≥1.8 kg) were 85.3 cm for WC and 23.25 kg/m(2) for BMI. CONCLUSION: Visceral fat mass ≥1.8 kg was positively associated with lifestyle-related disorders and closely related to WC and BMI cutoff values used to diagnose obesity. BIA may be a useful method for assessing visceral fat mass, and these findings provide important evidence for the use of BIA in the early detection of central obesity for preventing lifestyle-related disorders.

Translation and Validation of the Health Literacy Score-14 Questionnaire for Vietnamese Patients with Diabetes.

Introduction: Health literacy (HL) is a crucial indicator for health promotion and diabetes care improvement, but the available measurements are mostly in English. This study aimed to translate and validate the 14-item Health Literacy Scale (HLS-14) questionnaire from English to Vietnamese for patients with diabetes in Vietnam. Methods: We translated HLS-14 into Vietnamese in accordance with the World Health Organization guidelines and conducted a cross-sectional survey among 571 outpatients with type 2 diabetes using the HLS-14 Vietnamese version (HLS-14 VN). The reliability and validity of the tool were assessed using Cronbach's alpha, composite reliability (CR), average variance extracted (AVE), and maximum shared variance (MSV), and confirmatory analysis was conducted. Results: Cronbach's alpha coefficients for the three subscales as in the original version were 0.931, 0.810, and 0.928 for functional HL, communicative HL, and critical HL, respectively. However, AVE for critical HL was 0.488, which improved to 0.516 after the removal of one item in the communicative HL. For all subscales in the revised 13-item version (HLS-13 VN), CR was above 0.8, AVE was above 0.5, and MSV was less than AVE. Confirmatory analysis of HLS-13 VN revealed an acceptable fit with comparative fit index of 0.983, goodness-of-fit index of 0.963, and root mean squared error of approximation of 0.058. Conclusions: The reliability and validity of HLS-13 VN were confirmed. The tool is suitable for use in clinical settings in Vietnam to assess multidimensional HL in patients with type 2 diabetes.

Demographic and clinical characteristics of patients with zinc deficiency: analysis of a nationwide Japanese medical claims database.

Zinc deficiency, affecting more than 2 billion people globally, poses a significant public health burden due to its numerous unfavorable effects, such as impaired immune function, taste and smell disorders, pneumonia, growth retardation, visual impairment, and skin disorders. Despite its critical role, extensive large-scale studies investigating the correlation between patient characteristics and zinc deficiency still need to be completed. We conducted a retrospective, cross-sectional observational study using a nationwide Japanese claims database from January 2019 to December 2021. The study population included 13,100 patients with available serum zinc concentration data, excluding individuals under 20 and those assessed for zinc concentrations after being prescribed zinc-containing medication. Significant associations with zinc deficiency were noted among older adults, males, and inpatients. Multivariate analysis, adjusting for age and sex, indicated significant associations with comorbidities, including pneumonitis due to solids and liquids with an adjusted Odds Ratio (aOR) of 2.959; decubitus ulcer and pressure area (aOR 2.403), sarcopenia (aOR 2.217), COVID-19 (aOR 1.889), and chronic kidney disease (aOR 1.835). Significant association with medications, including spironolactone (aOR 2.523), systemic antibacterials (aOR 2.419), furosemide (aOR 2.138), antianemic preparations (aOR 2.027), and thyroid hormones (aOR 1.864) were also found. These results may aid clinicians in identifying patients at risk of zinc deficiency, potentially improving care outcomes.

Seroprevalence of SARS-CoV-2 antibodies among Japanese healthcare workers from 2020 to 2022 as assayed by two commercial kits.

Antibody tests are used as surveillance tools for informing health policy making. However, results may vary by type of antibody assay and timing of sample collection following infection. Long-term longitudinal cohort studies on antibody assay seropositivity have remained limited, especially among Asian populations. Using blood samples obtained at health physicals (2020-2022) of healthcare workers (mass vaccinated with mRNA COVID-19 vaccines) at a Japanese medical center, we measured N-specific antibodies using two commercially available systems. Roche Elecsys Anti-SARS-CoV-2 measures total antibodies and Abbott Alinity SARS-CoV-2 IgG measures only IgG. Among 2538 participants, seroprevalence was found to be 16.6% via total antibody assay versus 12.9% by IgG-only (including grayzone) by mid-June 2022. For 219 cases with a previous PCR-confirmed infection, positivity was 97.3% using total antibody assay versus 76.3% using IgG-only assay at the 2022 health physical. Using PCR positive test date as day 0, while the positivity of the total antibody assay was retained for the entire study period (until more than 24-months post-infection), the IgG-only assay's positivity declined after month 4. The Mantel-Haenszel test found a significant difference in the two assays' seropositivity, between stratified groups of "within 3 months" and "4 months or more" from infection (P < 0.001). Our study found significant differences in seropositivity over time of total antibody versus IgG-only assays, suggesting an optimal assay for retaining sensitivity over the entire infection period when designing seroprevalence studies.

Association between serum uric acid levels and achievement of target blood pressure among Japanese community residents with hypertension.

The authors examined the sex-specific association between serum uric acid (SUA) levels and achievement of target blood pressure among Japanese patients with hypertension. This cross-sectional study was conducted between January 2012 and December 2015 and examined 17 113 eligible participants (6499 men; 10 614 women) with hypertension among 66 874 Japanese community residents who underwent voluntary health checkups. Multivariate analysis was used to estimate the association between high SUA level (≥7.0 mg/dL for men and ≥6.0 mg/dL for women) and "therapeutic failure" in achieving target blood pressure (BP) of 140/90 and 130/80 mmHg in both sexes. Multivariate analysis revealed that high SUA level was significantly associated with failure to achieve the 130/80 mmHg treatment goal among men (AOR = 1.24, 95% CI = 1.03-1.50, p = .03). Among women, high SUA level was significantly associated with failure to achieve both the 130/80 and 140/90 mmHg treatment goals (AOR = 1.33, 95% CI = 1.20-1.47, p < .01 and AOR = 1.17, 95% CI = 1.04-1.32, p < .01, respectively). Each increase in SUA quartile was positively associated with increases in systolic BP (SBP) and diastolic BP (DBP) (p < .01 for trend) in both sexes. SBP and DBP in each quartile (Q2-Q4) were also significantly higher compared with those of Q1 in both sexes (p < .01). Our data confirms the difficulties in maintain goal BP control in those with elevated SUA.

Evaluation of a simple protein extraction method for species identification of clinically relevant staphylococci by matrix-assisted laser desorption ionization-time of flight mass spectrometry.

In clinical microbiology, bacterial identification is labor-intensive and time-consuming. A solution for this problem is the use of matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS). In this study, we evaluated a modified protein extraction method of identification performed on target plates (on-plate extraction method) with MALDI-TOF (Bruker Microflex LT with Biotyper version 3.0) and compared it to 2 previously described methods: the direct colony method and a standard protein extraction method (standard extraction method). We evaluated the species of 273 clinical strains and 14 reference strains of staphylococci. All isolates were characterized using the superoxide dismutase A sequence as a reference. For the species identification, the on-plate, standard extraction, and direct colony methods identified 257 isolates (89.5%), 232 isolates (80.8%), and 173 isolates (60.2%), respectively, with statistically significant differences among the three methods (P < 0.05). In conclusion, the on-plate extraction method is at least as good as standard extraction in identification rate and has the advantage of a shorter processing time.

Achievement of target blood pressure among community residents with hypertension and factors associated with therapeutic failure in the northern territory of Japan.

OBJECTIVE: This study aimed to determine the rate of achieving the target blood pressure (BP) defined by Japanese hypertension management guidelines and to examine factors associated with achieving the target BP. METHODS: This cross-sectional study, which was conducted between January 2012 and December 2015, examined the BP control status and associated factors among 9,016 Japanese community residents with hypertension. Residents were divided into the following six groups: G1, young, middle-aged, and early-phase elderly patients; G2, patients with cerebrovascular disease; G3, patients with coronary artery disease; G4, patients with chronic kidney disease with proteinuria; G5, patients with diabetes; and G6, patients with chronic kidney disease without proteinuria. BP target achievement rates were calculated for each group. A multivariate analysis identified factors associated with "therapeutic failure" of target BP. RESULTS: The target BP was achieved by 52.6% participants in G1, 84.3% in G2, 50.6% in G3, 45.6% in G4, 48.7% in G5, and 75.0% in G6. The body mass index and receiving antilipidemic medication were associated with therapeutic failure. CONCLUSION: This study shows that achievement rates for treatment goals among Japanese patients with hypertension are still low. Body mass index and treatment of dyslipidemia may be associated with the control of BP.

Relief Effect of Carbon Dioxide Insufflation in Transnasal Endoscopy for Health Checks-A Prospective, Double-Blind, Case-Control Trial.

CO2 insufflation has proven effective in reducing patients' pain after colonoscopies but has not been examined in esophagogastroduodenoscopies. Therefore, we examined the effect of CO2 insufflation in examinees who underwent transnasal endoscopies without sedation. This study is a single-center, prospective, double-blind, case-control trial conducted between March 2017 and August 2018. Subjects were assigned weekly to receive insufflation with either CO2 or air. The primary outcome was improvement of abdominal pain and distension at 2 h and 1-day postprocedure. In total, 336 and 338 examinees were assigned to the CO2 and air groups, respectively. Visual analog scale (VAS) scores for abdominal distension (15.4 vs. 25.5; p < 0.001) and distress from flatus (16.0 vs. 28.8; p < 0.001) at 2 h postprocedure were significantly reduced in the CO2 group. VAS scores for pain during the procedure (33.5 vs. 37.1; p = 0.059) and abdominal pain after the procedure (3.9 vs. 5.7; p = 0.052) also tended to be lower at 2 h postprocedure, but all parameters showed no significant difference at 1-day postprocedure. All procedures were safely completed through the planned program, and no apparent adverse events requiring treatment or follow-up occurred. In conclusion, CO2 insufflation may reduce postprocedural abdominal discomfort from transnasal esophagogastroduodenoscopies. (UMIN000028543).

An association between subcutaneous fat mass accumulation and hypertension.

Evidence to assess relationships between subcutaneous fat area (SFA) and lifestyle-related diseases, including hypertension, remains limited. The aim of this study was to investigate the relationship between SFA and hypertension. This study was a single-institution, cross-sectional study of 1,899 eligible Japanese participants who underwent health checkups between December 2016 and December 2018. All patients were measured for SFA and visceral fat area (VFA) by abdominal computed tomography (CT). SFA was divided into quartiles by gender, and multivariate logistic regression analysis was performed to estimate associations between SFA quartiles (Q) and hypertension. Mean age and SFA were 60.9 9 (standard devastation [SD]:12.0) years and 123.0 (56.9) cm2 in men, and 60.6 (12.8) years and 146.6 (79.0) cm2 in women, respectively. Risk of hypertension from multivariate regression modeling compared with the lowest quartile (Q) in both sexes was as follows: for men Q2 [odds ratio (OR), 1; 95% confidence interval (CI), 0.55-1.51 ], Q3 (OR, 1.73; 95%CI, 1.17-2.56), and Q4 (OR, 1.96; 95%CI, 1.31-2.94); for women Q2 (OR, 0.87; 95%CI, 0.48-1.58), Q3 (OR, 1.73; 95%CI, 1.02-2.95), and Q4 (OR, 2.54; 95%CI, 1.51-4.28). The optimal SFA cutoff value at risk of hypertension was 114.7 cm2 in men and 169.3 cm2 in women. The prevalence of hypertension was positively associated with SFA quartiles in both genders. The present results may indicate the necessity of considering not only VFA, but also SFA for the primary and secondary prevention of hypertension.

Factors influencing activated clotting time following heparin administration for the initiation of cardiopulmonary bypass.

OBJECTIVES: Initiation of cardiopulmonary bypass (CPB) for open-heart surgery requires that heparin be administered and reach an adequate value of activated clotting time (ACT). We previously introduced a new heparin formula that considered the preoperative ACT. In this study, we determined other factors affecting ACT. METHODS: Adult patients who underwent cardiac surgery using CPB were divided into two groups according to their ACT value after the initial administration of heparin during surgery. ACT above 450 s was defined as "Reach", and this group was compared to the "Short" group with ACT below 450 s. RESULTS: The Reach and Short groups included 334 (64.7%) and 182 (35.3%) cases, respectively. Univariate analysis indicated that preoperative heparin use, age ≥ 80 years, New York Heart Association classification 4, white blood cell counts above the higher limit, hematocrit below the lower limit, platelet cell counts below the lower limit, low albumin levels, moderate renal dysfunction, high C-reactive protein levels, high brain natriuretic peptide levels, and moderate deterioration of left ventricular ejection fraction were associated with the effects of heparin. Multivariate analysis revealed that age ≥ 80 years (odds ratio [OR] 2.53, 95% confidence interval [95%CI] 1.41-5.24), New York Heart Association classification 4 (OR = 4.44, 95%CI 1.59-15.35), and platelet count below the lower limit (OR 0.37, 95%CI 0.31-0.85) were associated with the effects of heparin. CONCLUSION: Old age, heart failure, and lower platelet counts affected heparin activity. The dose of heparin should be considered in those patients to reach the target ACT.

Efficacy and safety of semaglutide in glycemic control, body weight management, lipid profiles and other biomarkers among obese type 2 diabetes patients initiated or switched to semaglutide from other GLP-1 receptor agonists.

PURPOSE: Evidence of the efficacy and safety of semaglutide among patients with type 2 diabetes who were initiated on or were switched to semaglutide from other GLP-1 RAs remains limited. The objective of this study was to investigate the short-term effects of switching to semaglutide from other GLP-1 RAs. METHODS: This retrospective cohort study evaluated patients with type 2 diabetes who were initiated on or were switched to semaglutide due to poor diabetes control with other GLP-1 RAs or other medications, or obesity. HbA1c, body weight, serum creatinine, serum uric acid, parameters of lipid metabolism, and parameters of liver function were measured before and 6 months after administration of semaglutide. RESULTS: A total of 50 patients were registered in the study. After switching to semaglutide (n = 43), HbA1c and body weight significantly decreased (p < 0.01, p < 0.01), respectively. The same findings were observed in semaglutide-naïve patients (p = 0.04, p < 0.02) (n = 7). Serum uric acid, total cholesterol, triglycerides, and urinary albumin-creatinine ratio decreased significantly as well (p = 0.04, p = 0.04, p = 0.02, p = 0.04), whereas serum creatinine did not change significantly (p = 0.51). CONCLUSIONS: Semaglutide showed excellent efficacy, even in patients switched from other GLP-1 RAs. Semaglutide appears to be a promising agent for blood glucose and body weight control in obese type 2 diabetes mellitus patients and could be more potent in treating type 2 diabetes than existing GLP-1 RAs.
