Clinical Outcomes of Mitral Valve Surgery in Atrial Functional Mitral Regurgitation in the REVEAL-AFMR Registry.

Importance: The characteristics and treatment strategies of atrial functional mitral regurgitation (AFMR) are poorly understood. Objective: To investigate the prevalence, clinical characteristics, and outcomes of mitral valve (MV) surgery in AFMR. Design, Setting, and Participants: This retrospective cohort study, called the Real-World Observational Study for Investigating the Prevalence and Therapeutic Options for Atrial Functional Mitral Regurgitation (REVEAL-AFMR), was conducted across 26 Japanese centers (17 university hospitals, 1 national center, 3 public hospitals, and 5 private hospitals). All transthoracic echocardiography procedures performed from January 1 to December 31, 2019, were reviewed to enroll adult patients (aged ≥20 years) with moderate or severe AFMR, defined by preserved left ventricular function, a dilated left atrium, and an absence of degenerative valvular changes. Data were analyzed from May 8, 2023, to May 16, 2024. Exposures: Mitral valve surgery, with or without tricuspid valve intervention. Main Outcomes and Measures: The primary composite outcome included heart failure hospitalization and all-cause mortality. Results: In 177 235 patients who underwent echocardiography, 8867 had moderate or severe MR. Within this group, 1007 (11.4%) were diagnosed with AFMR (mean [SD] age, 77.8 [9.5] years; 55.7% female), of whom 807 (80.1%) had atrial fibrillation. Of these patients, 113 underwent MV surgery, with 92 (81.4%) receiving concurrent tricuspid valve surgery. Patients who underwent surgery were younger but had more severe MR (57.5% [n = 65] vs 9.4% [n = 84]; P < .001), a larger mean (SD) left atrial volume index (152.5 [97.8] mL/m2 vs 87.7 [53.1] mL/m2; P < .001), and a higher prevalence of heart failure (according to the New York Heart Association class III [marked limitation of physical activity] or class IV [symptoms of heart failure at rest], 26.5% [n = 30] vs 9.3% [n = 83]; P < .001) than those who remained under medical therapy. During a median follow-up of 1050 days (IQR, 741-1188 days), 286 patients (28.4%) experienced the primary outcome. Despite a more severe disease status, only the surgical group showed a decrease in natriuretic peptide levels at follow-up and had a significantly lower rate of the primary outcome (3-year event rates were 18.3% vs 33.3%; log-rank, P = .03). Statistical adjustments did not alter these findings. Conclusions and Relevance: The findings of this cohort study suggest that in patients with AFMR, who were typically older and predominantly had atrial fibrillation, MV surgery was associated with lower rates of adverse clinical outcomes. Future studies are warranted to investigate a possible causal relationship to better regulate cardiovascular medicine.

Multicenter validation study for automated left ventricular ejection fraction assessment using a handheld ultrasound with artificial intelligence.

We sought to validate the ability of a novel handheld ultrasound device with an artificial intelligence program (AI-POCUS) that automatically assesses left ventricular ejection fraction (LVEF). AI-POCUS was used to prospectively scan 200 patients in two Japanese hospitals. Automatic LVEF by AI-POCUS was compared to the standard biplane disk method using high-end ultrasound machines. After excluding 18 patients due to infeasible images for AI-POCUS, 182 patients (63 ± 15 years old, 21% female) were analyzed. The intraclass correlation coefficient (ICC) between the LVEF by AI-POCUS and the standard methods was good (0.81, p < 0.001) without clinically meaningful systematic bias (mean bias -1.5%, p = 0.008, limits of agreement ± 15.0%). Reduced LVEF < 50% was detected with a sensitivity of 85% (95% confidence interval 76%-91%) and specificity of 81% (71%-89%). Although the correlations between LV volumes by standard-echo and those by AI-POCUS were good (ICC > 0.80), AI-POCUS tended to underestimate LV volumes for larger LV (overall bias 42.1 mL for end-diastolic volume). These trends were mitigated with a newer version of the software tuned using increased data involving larger LVs, showing similar correlations (ICC > 0.85). In this real-world multicenter study, AI-POCUS showed accurate LVEF assessment, but careful attention might be necessary for volume assessment. The newer version, trained with larger and more heterogeneous data, demonstrated improved performance, underscoring the importance of big data accumulation in the field.

High body mass index and triglyceride levels at health checkups increase the risk of new-onset chronic kidney disease and worsening renal function: the TAMA MED Project-CKD.

BACKGROUND: Health checkups are important in patients with chronic kidney disease (CKD), which is not easily accompanied by subjective symptoms. CKD can be caused or aggravated by factors that have not yet been identified. METHODS: This retrospective cohort study included 7 483 patients who underwent specific annual health checkups at a medical institution in Tama City, did not have CKD in 2012, and continued to undergo checkups (aged 40-74 years). We examined the risk factors for new-onset CKD and 1.5-fold increase in serum creatinine levels among laboratory values from 2012 to 2020. RESULTS: Age, body mass index (BMI), triglyceride levels, atrial fibrillation, and medication for hypertension (HT) and diabetes mellitus were independent risk factors for proteinuria, whereas current smoking, BMI, systolic blood pressure (SBP), and medication for HT were independent risk factors for estimated glomerular filtration rate < 60 mL/min/1.73 m2. SBP, triglyceride levels and medication for HT were risk factors for a 1.5-fold increase in serum creatinine levels during course of the study. The cut-off values of BMI for eGFR < 60 mL/min/1.73 m2 were 22.2 (men 24.7, women 22.1) kg/m2 and fasting triglyceride levels for a 1.5-fold increase in serum creatinine level were 171 (men 247, women 170) mg/dL, respectively. CONCLUSIONS: Health checkups provide information to prevent new-onset CKD and worsening of renal function. It is necessary to increase the rate of health checkups and visits to medical institutions after health checkups as well as to use these results for health guidance.

Upward-directed exit-site of the swan-neck catheter and "Easy-to-disinfect the backside area of exit-site" may prevent PD complications.

BACKGROUND: Upward-directed exit-site has been believed to be the worst for frequent ESI by an old retrospective study using straight catheters. No comparison study of 3 exit-site directions using swan-neck catheter has been performed regarding which direction is the best for our endpoints, Easy-to-see the backside area of exit-site: ESBE, Easy-to-disinfect the backside area of exit-site: EDBE, reduction of both exit-site infection (ESI), symptomatic catheter dislocation and peritonitis. METHODS: We assessed the relationship of exit-site direction with our endpoints in a quantitative cross-sectional, multicentered questionnaire survey. Patients who received either non-surgical catheter implantation or exit-site surgery were excluded. RESULTS: The numbers (percentage) of exit-site directions in included 291 patients were upward 79 (26.0), lateralward 108 (37.5) and downward 105 (36.5). Cochran-Armitage analysis showed a significant step-ladder increase in the prevalence of ESI as the direction changed from upward to lateralward to downward (0.15 ± 0.41, 0.25 ± 0.54, 0.38 ± 0.69 episodes/patient-year, p = 0.03). Multivariable regression analysis revealed the upward exit-site independently associates with both higher frequency of ESBE (OR 5.55, 95% CI 2.23-16.45, p < 0.01) and reduction of prevalence of ESI (OR 0.55, 95%CI 0.27-0.98, p = 0.04). Positive association between the prevalence of symptomatic catheter dislocation and ESI (OR 2.84, 95% CI 1.27-7.82, p = 0.01), and inverse association between EDBE and either prevalence of symptomatic catheter dislocation (OR 0.27, 95% CI 0.11-0.72) or peritonitis (OR 0.48, 95% CI 0.23-0.99) observed. CONCLUSION: Upward-directed swan-neck catheter exit-site may be the best for both ESBE and prevention of ESI. EDBE may reduce catheter dislocation and peritonitis. Symptomatic catheter dislocation may predict ESI.

Prognostic impact of MitraScore in elderly Asian patients with heart failure: sub-analysis of FRAGILE-HF.

AIMS: MitraScore is a novel, simple, and manually calculatable risk score developed as a prognostic model for patients undergoing transcatheter edge-to-edge repair (TEER) for mitral regurgitation. As its components are considered prognostic in heart failure (HF), we aimed to investigate the usefulness of the MitraScore in HF patients. METHODS AND RESULTS: We calculated MitraScore for 1100 elderly patients (>65 years old) hospitalized for HF in the prospective multicentre FRAGILE-HF study and compared its prognostic ability with other simple risk scores. The primary endpoint was all-cause deaths, and the secondary endpoints were the composite of all-cause deaths and HF rehospitalization and cardiovascular deaths. Overall, the mean age of 1100 patients was 80 ± 8 years, and 58% were men. The mean MitraScore was 3.2 ± 1.4, with a median of 3 (interquartile range: 2-4). A total of 326 (29.6%), 571 (51.9%), and 203 (18.5%) patients were classified into low-, moderate-, and high-risk groups based on the MitraScore, respectively. During a follow-up of 2 years, 226 all-cause deaths, 478 composite endpoints, and 183 cardiovascular deaths were observed. MitraScore successfully stratified patients for all endpoints in the Kaplan-Meier analysis (P < 0.001 for all). In multivariate analyses, MitraScore was significantly associated with all endpoints after covariate adjustments [adjusted hazard ratio (HR) (95% confidence interval): 1.22 (1.10-1.36), P < 0.001 for all-cause deaths; adjusted HR 1.17 (1.09-1.26), P < 0.001 for combined endpoints; and adjusted HR 1.24 (1.10-1.39), P < 0.001 for cardiovascular deaths]. The Hosmer-Lemeshow plot showed good calibration for all endpoints. The net reclassification improvement (NRI) analyses revealed that the MitraScore performed significantly better than other manually calculatable risk scores of HF: the GWTG-HF risk score, the BIOSTAT compact model, the AHEAD score, the AHEAD-U score, and the HANBAH score for all-cause and cardiovascular deaths, with respective continuous NRIs of 0.20, 0.22, 0.39, 0.39, and 0.29 for all-cause mortality (all P-values < 0.01) and 0.20, 0.22, 0.42, 0.40, and 0.29 for cardiovascular mortality (all P-values < 0.02). CONCLUSIONS: MitraScore developed for patients undergoing TEER also showed strong discriminative power in HF patients. MitraScore was superior to other manually calculable simple risk scores and might be a good choice for risk assessment in clinical practice for patients receiving TEER and those with HF.

A Case Report of Mixed-type Dyspnoea Diagnosed via Non-invasive and Invasive Cardiopulmonary Exercise Tests.

A gas exchange analysis with the cardiopulmonary exercise test is effective in discriminating non-cardiogenic components of limited exercise tolerance and is important for use in combination with the diastolic stress test. An 80-year-old woman with progressive exertional dyspnoea, hypertension, and untreated bronchial asthma was diagnosed with heart failure with a preserved ejection fraction by invasive testing. Diuretics were initiated, which resulted in partial symptom improvement. A subsequent non-invasive test revealed a reduced breathing reserve, suggesting exertional dyspnoea complications linked to lung disease. Bronchodilators were administered, which further improved the symptoms.

Secondary immunoglobulin A nephropathy with gross hematuria leading to rapidly progressive glomerulonephritis following severe acute respiratory syndrome coronavirus 2 vaccination: a case report.

BACKGROUND: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has been followed by many reports of the development and relapse of autoimmune diseases associated with SARS-CoV-2 vaccination. Some of these reports have involved relapse or onset of immunoglobulin A (IgA) nephropathy following SARS-CoV-2 vaccination. Here, we report on a patient with IgA nephropathy who presented with gross hematuria and rapidly progressive glomerulonephritis following SARS-CoV-2 vaccination. CASE PRESENTATION: A 63-year-old male patient with a history of habitual tonsillitis underwent bilateral tonsillectomy. He had a history of alcoholic cirrhosis of the liver and microscopic hematuria and proteinuria were indicated during a health checkup 2 years before hospital admission. He developed hematuria after the SARS-CoV-2 vaccination, which led to rapidly progressive glomerulonephritis, for which he was hospitalized. A renal biopsy led to the diagnosis of IgA nephropathy. Although pulse steroid therapy during his condition resulted in hepatic encephalopathy, three courses combined with mizoribine improved his renal function. CONCLUSION: SARS-CoV-2 mRNA vaccines activate T cells, which are involved in the pathophysiology of IgA nephropathy. Therefore, this case suggests that the exacerbation of IgA nephropathy by the vaccine favors the vasculitis aspect of the disease.

Usefulness of HANBAH Score in Japanese Patients With Acute Heart Failure.

The HANBAH score is a novel simple risk score consisting of hemoglobin level, age, sodium (N) level, blood urea nitrogen level, atrial fibrillation, and high-density lipoprotein. We aimed to validate this score in an external population. This retrospective study included 744 patients hospitalized for acute heart failure between 2015 and 2019. Each of the following criteria was scored as 1 point: hemoglobin level (<13.0 g/L for men and <12.0 g/L for women), atrial fibrillation, age (>70 years), serum blood urea nitrogen level (>26 mg/100 ml for men and >28 mg/100 ml for women), serum high-density lipoprotein level (<25 mg/100 ml), and serum sodium level (<135 mg/100 ml). HANBAH scores were available for 736 patients (age, 75 ± 13 years; 60% male; reduced [<40%] and preserved ejection fraction [≥50%]: 35% and 49%, respectively). All-cause death during follow-up, a composite of death and heart failure rehospitalization, and in-hospital death were observed in 173, 274, and 51 patients, respectively. The HANBAH score was significantly associated with these end points after adjustment for covariates (adjusted hazard ratio 1.38 [95% confidence interval 1.16 to 1.64], p <0.001; 1.27 [1.11 to 1.45], p <0.001; and 1.66 [1.18 to 2.33], p <0.001, respectively). Receiver operating characteristic and net reclassification improvement analyses showed that the HANBAH score performed significantly better than AHEAD (atrial fibrillation, hemoglobin [anemia], elderly, abnormal renal parameters, diabetes mellitus) and AHEAD-U (AHEAD with uric acid) scores and similar to the multi-domain ACUTE HF score for all end points. In conclusion, the HANBAH score showed powerful risk stratification in this external Japanese cohort. Despite its simplicity, it performed better than other simple risk scores and similar to a multidomain risk score.

Development of angiogenic periglomerular microvessels after acute glomerular lesions in IgA nephropathy.

AIM: To clarify the clinicopathological characteristics and role of periglomerular angiogenesis in IgA nephropathy. METHODS AND RESULTS: The renal biopsy specimens of 114 patients with IgA nephropathy were examined. Among them, 46 (40%) showed periglomerular angiogenesis around the glomeruli. CD34 and α-smooth muscle actin (α-SMA) staining in serial sections revealed that these vessels contained CD34+ α-SMA+ microarterioles along with CD34+ α-SMA- capillaries. We termed these "periglomerular microvessels (PGMVs)". Patients with PGMVs (PGMV group) had clinically and histologically more severe disease than those without PGMVs (non-PGMV group) at the time of biopsy. Even after adjusting for age, there were significant differences in the degree of proteinuria and estimated glomerular filtration rate reduction between the PGMV and non-PGMV groups. The PGMV group showed a higher incidence of segmental and global glomerulosclerosis and crescentic lesions than the non-PGMV group (P < 0.01). Here, PGMVs were undetectable in the acute and active inflammation phase, but were observed in the acute to chronic or chronic glomerular remodelling phase. PGMVs mainly developed around glomerular adherent lesions to the Bowman's capsule with small or minimal glomerular sclerotic lesions. Conversely, they were rarely observed in segmental sclerosis areas. CONCLUSION: The PGMV group is clinically and pathologically more severe than the non-PGMV group; however, they were undetectable in segmental sclerosis with mesangial matrix accumulation. PGMVs might occur after acute/active glomerular lesions, suggesting that PGMVs may inhibit segmental glomerulosclerosis progression and could be a marker for good repair response after acute/active glomerular injury in severe IgA nephropathy cases.

A case of adult patent ductus arteriosus-associated infective endarteritis who was successfully treated with only antibiotics.

Patent ductus arteriosus-associated infective endarteritis (PDA-IE) is an extremely rare complication of PDA in recent years. In this report, we describe a case of PDA-IE complicated by septic pulmonary embolism who was successfully treated with only antibiotics.

Artificial intelligence-based point-of-care lung ultrasound for screening COVID-19 pneumoniae: Comparison with CT scans.

BACKGROUND: Although lung ultrasound has been reported to be a portable, cost-effective, and accurate method to detect pneumonia, it has not been widely used because of the difficulty in its interpretation. Here, we aimed to investigate the effectiveness of a novel artificial intelligence-based automated pneumonia detection method using point-of-care lung ultrasound (AI-POCUS) for the coronavirus disease 2019 (COVID-19). METHODS: We enrolled consecutive patients admitted with COVID-19 who underwent computed tomography (CT) in August and September 2021. A 12-zone AI-POCUS was performed by a novice observer using a pocket-size device within 24 h of the CT scan. Fifteen control subjects were also scanned. Additionally, the accuracy of the simplified 8-zone scan excluding the dorsal chest, was assessed. More than three B-lines detected in one lung zone were considered zone-level positive, and the presence of positive AI-POCUS in any lung zone was considered patient-level positive. The sample size calculation was not performed given the retrospective all-comer nature of the study. RESULTS: A total of 577 lung zones from 56 subjects (59.4 ± 14.8 years, 23% female) were evaluated using AI-POCUS. The mean number of days from disease onset was 9, and 14% of patients were under mechanical ventilation. The CT-validated pneumonia was seen in 71.4% of patients at total 577 lung zones (53.3%). The 12-zone AI-POCUS for detecting CT-validated pneumonia in the patient-level showed the accuracy of 94.5% (85.1%- 98.1%), sensitivity of 92.3% (79.7%- 97.3%), specificity of 100% (80.6%- 100%), positive predictive value of 95.0% (89.6% - 97.7%), and Kappa of 0.33 (0.27-0.40). When simplified with 8-zone scan, the accuracy, sensitivity, and sensitivity were 83.9% (72.2%- 91.3%), 77.5% (62.5%- 87.7%), and 100% (80.6%- 100%), respectively. The zone-level accuracy, sensitivity, and specificity of AI-POCUS were 65.3% (61.4%- 69.1%), 37.2% (32.0%- 42.7%), and 97.8% (95.2%- 99.0%), respectively. INTERPRETATION: AI-POCUS using the novel pocket-size ultrasound system showed excellent agreement with CT-validated COVID-19 pneumonia, even when used by a novice observer.

Endothelial function measured by peripheral arterial tonometry in patients with chronic myeloid leukemia on tyrosine kinase inhibitor therapy: a pilot study.

BACKGROUND: Arterial occlusive events are an emerging problem in patients with chronic myeloid leukemia (CML) receiving tyrosine kinase inhibitor (TKI) therapy. Endothelial cell damage is thought to play an important role in the development of vascular events. Measurement of the peripheral vasodilator response by peripheral arterial tonometry (PAT) has reportedly been useful in the non-invasive assessment of endothelial dysfunction. To date, no studies have assessed endothelial function using PAT in patients with CML receiving TKIs. METHOD: We measured the reactive hyperemia index (RHI) using PAT in young patients with CML (men aged ≤ 55 years and women aged ≤ 65 years) receiving TKIs. RESULTS: Thirty patients with CML were examined (mean age, 43.5 ± 9.8 years; men, 57%). The median RHI was 1.81. Among these patients, 16.7% and 83.3% were taking imatinib and second- or third-generation TKIs, respectively. There were no differences in the baseline characteristics between the low RHI (< 1.67, n = 10), borderline RHI (≥ 1.67 and < 2.10, n = 14), and normal RHI (≥ 2.10, n = 6) groups. Serum uric acid (UA) levels and the RHI were significantly negatively correlated (r = -0.40, p = 0.029). CONCLUSION: One-third of young patients with CML receiving TKI therapy were classified as having a low RHI. The RHI was negatively correlated with serum UA level. Larger prospective studies are necessary to examine whether the RHI predicts cardiovascular events in such patients.

Factors Influencing Sarcopenic Changes in YUBI-WAKKA Finger-Ring Test Results After One Year: A Retrospective Observational Study.

Background: The YUBI-WAKKA (finger-ring) test was developed and validated as a predictor of sarcopenia, physical disability, and even mortality. We focused on the sarcopenic status and subsequent changes after 1 year using this test and analyzed factors related to these changes. We also examined the robustness of this test by administering it alongside annual checkups held in local clinics. Methods: We conducted the study to investigate the data of the annual checkup of National Health Insurance at primary care clinics in 2017 and 2018 in Tama City. We studied the participants in a retrospective observational way. The participants of the YUBI-WAKKA test were a total of 5,405 and 4,391 residents between the ages of 65 and 74 years. We first compared anthropological biomarkers of two groups, those that had calves larger than their own finger-ring and those that had calves smaller than their own finger-ring. Then, we compared these results to those from the previous year's 1,048 pairs of data. We were particularly interested in changes from larger to smaller, which we defined here as a sarcopenic change, and performed multivariate logistic regression analysis with forced entry methods to determine the related factors. We also calculated the concordant rate of the test results after 1 year. Results: In total, 14% (men) and 16% (women) each year received a positive (sarcopenic) YUBI-WAKKA test result. The factors related to this sarcopenic change in 1 year were low uric acid in men and a low or decreasing body mass index and increased hemoglobin and alanine aminotransferase in women. The concordant rates of the larger, just fit and smaller groups following finger-ring testing were 72.8%, 63.5%, and 52.0%, respectively. Conclusions: We propose that low uric acid and low or reducing body weight were related to low muscle mass and that ALT and Hb may be indirectly related to sarcopenia. These could be predictive factors to determine sarcopenia-prone individuals. The YUBI-WAKKA (finger-ring) test results and their change were considered to be a sustainable and reasonable way to use in the community with small effort to find those who are at high risk for sarcopenia among the elderly population and who may require intervention.

External validation of the ACUTE HF score for risk stratification in acute heart failure.

BACKGROUND: The ACUTE HF score is a simple risk score that predicts the prognosis of patients with acute heart failure (HF) using clinical and echocardiographic parameters. As this score was developed for a small European population, we aimed to validate this score in an external population. METHODS AND RESULTS: This retrospective observational cohort analysis included patients hospitalized with acute HF during 2015-2019. Of 744 patients, 703 patients with available ACUTE HF scores were analyzed (75 ± 13 years; 61% male; left ventricular ejection fraction [LVEF] 49 ± 17%). Approximately one-third (34.4%) of the patients had reduced LVEF (<40%), and 51.4% exhibited preserved LVEF (≥50%). During a median follow-up of 452 days, primary and secondary outcomes were observed in 110 and 204 patients, respectively. The ACUTE HF score successfully stratified patients for primary (all-cause mortality) and secondary endpoints (a composite of all-cause mortality and heart failure rehospitalization) in Kaplan-Meier analyses (log-rank test, P < 0.001). Multivariable Cox proportional hazards models showed that the score was significantly independently associated with both primary and secondary endpoints after adjusted by covariates (P < 0.001). CONCLUSION: We validated the risk prediction ability of ACUTE HF score in an Asian population. This score may be applicable in clinical practice.

A possible role of classical complement pathway activation in the pathogenesis of immunoglobulin G nephropathy: a case report.

Immunoglobulin G (IgG) nephropathy refers to a rare group of diseases characterized by deposits of IgG in the mesangial region. However, IgG nephropathy is controversial as a single disease entity, and its pathogenesis remains to be elucidated. In the present report, we discuss a case of IgG nephropathy in which we observed activation of the classical complement pathway.A 47-year-old woman was admitted to our hospital with nephrotic syndrome. Light-microscopic examination revealed neither proliferative nor sclerotic lesions in the glomeruli. However, unusual and large deposits were observed in the paramesangial area. An immunofluorescence study revealed predominant IgG and C1q and slight C3 deposits in the paramesangial area, suggesting immune-complex-type glomerular disease. An electron microscopic study also revealed different sizes of non-organized electron-dense deposits with a similar pattern of distribution, which were accompanied by foot process effacement. Clinically, there was no evidence of systemic diseases, such as infectious or autoimmune diseases (including systemic lupus erythematosus). Based on these findings, she was diagnosed with IgG nephropathy and treated with prednisolone. Steroid therapy was effective, and complete remission was maintained.Additional immunological examination revealed that IgG deposits were polyclonal and consisted mainly of the IgG1 and IgG3 subclasses. Furthermore, staining was positive for C4d and C5b-9. The present findings indicate that the pathogenesis of IgG nephropathy in our patient may have involved activation of the classical complement pathway.

Sarcopenia and coexistent risk factors detected using the 'Yubi-wakka' (finger-ring) test in adults aged over 65 years in the public annual health check-up in Tama City, Tokyo: a cross-sectional study.

OBJECTIVES: To examine the positive rate of sarcopenia using the 'Yubi-wakka' (finger-ring) test and associated risk factors among adults aged 65 years and older. DESIGN: Cross-sectional study. SETTING: We used the Yubi-wakka test, which has been developed and validated as a predictor of sarcopenia, frailty, disability and mortality. A positive test result is indicated by a smaller calf circumference than the finger-ring. The test was administered during annual health check-ups among residents of Tama City, Japan. PARTICIPANTS: During the 2019 fiscal year, 12 894 individuals aged 65 years and older underwent the Yubi-wakka test at primary care clinics. INTERVENTIONS: Examinees conducted the test themselves in a seated position. They formed a ring around their calf using both thumbs and index fingers and judged whether their calf was larger, the same or smaller than their finger-ring. PRIMARY AND SECONDARY OUTCOME MEASURES: We compared anthropometric and serological data between the positive (smaller calf) and negative (larger calf) test result groups. RESULTS: The positive rate was 15.4% among men and 18.5% among women. The prevalence of a positive result was higher in those aged ≥80 years than in younger age groups in both sexes (men: 22.8%; women: 28.8%). Multivariate logistic regression analysis showed that a diagnosis of metabolic syndrome was a risk factor for detecting a positive test result in women aged 65-74 years (OR 3.445; 95% CI 1.44 to 8.29) and ≥75 years (OR 3.37; 95% CI 1.97 to 5.78). CONCLUSIONS: Because the Japanese population is healthy and lives long, interventions against sarcopenia are important, especially for older adults aged >75 years. The presence of metabolic syndrome may be a risk factor for sarcopenia (as detected by the Yubi-wakka test) and future frailty, and requires closer attention, especially among women.

Atypical Shone's Complex Diagnosed at 70 Years Old: Presenting with Double-orifice Mitral Valve, Bicuspid Aortic Valve, and Aortic Coarctation.

Atypical Shone's complex is a rare congenital anomaly involving a left-sided obstructive lesion of two or three cardiovascular levels. A 70-year-old man with dyspnea on exertion was diagnosed with severe aortic stenosis (AS) with a bicuspid valve, complicated by severe aortic coarctation (CoA) and a double-orifice mitral valve. He underwent surgery for AS and CoA in one session. It is important to search for complicated malformations, even in cases of bicuspid aortic valve found in old age.

Effectiveness of real-time tele-ultrasound for echocardiography in resource-limited medical teams.

BACKGROUND: Echocardiography is a first-line tool for the screening of patients with cardiac dysfunction. However, the mastery of echocardiography requires significant training, and not all medical teams involve an echocardiography specialist. Telemedicine approaches can potentially improve the quality of echocardiography in resource-limited situations. METHODS: We used a novel tablet-based hand-held ultrasound device that enables tele-ultrasound- a real-time video telecommunication with remote control for ultrasound images. A trainee scanned patients with various cardiovascular diseases and interpreted the images. Subsequently, the same trainee re-scanned the same patients and re-interpreted the same images using tele-ultrasound with an echocardiography specialist. An examination on the same patients by a blinded specialist was considered the gold standard. RESULTS: We included 31 patients (median 77 [interquartile range 68-84] years old, 42% women). Mean absolute errors in left ventricular (LV) end-diastolic and end-systolic diameters, visual LV ejection fraction, and tricuspid annular plane systolic excursion decreased significantly after tele-ultrasound advice (5.9 mm, 5.8 mm, 8.6%, and 4.5 to 1.6 mm, 2.8 mm, 0.7%, and 1.8 mm, respectively, all p < 0.001), and intra-class correlation coefficients improved (0.76, 0.84, 0.68, and 0.44 to 0.96, 0.93, 0.99, and 0.90, respectively). Notably, with tele-advice, the trainee's examination showed perfect agreement with that of the specialist in classifying LV ejection fraction (> 50%, 50-35%, or > 35%) and identifying significant valvular heart diseases. CONCLUSION: Real-time tele-ultrasound improved a trainee's echocardiography results to those of a specialist-level examination. This approach might be helpful in resource-limited medical teams where echocardiographic specialists are not readily available.

Immune Checkpoint Inhibitor as a Therapeutic Choice for Double Cancer: A Case Series.

BACKGROUND: Hepatocellular carcinoma (HCC) occasionally presents with simultaneous or metachronous primary malignancies of other organs. Despite the limited scope of cytocidal anticancer drugs or molecular targeted agents, immune checkpoint inhibitors (ICIs) can still be used for various malignancies. Here, we present cases of double cancers including HCC treated with ICIs. CASE REPORT: Case 1: A 70-year-old man with lung cancer and 80-mm HCC underwent nivolumab therapy. The sizes of both cancers remained constant for nine months. Case 2: A 58-year-old man with pharyngeal cancer and HCC. Nivolumab was administered, but was withdrawn after one session because of progressive disease. Case 3: A 71-year-old man with a 5 cm HCC invading the inferior vena cava, and early esophageal cancer. HCC showed a significant volume reduction and esophageal cancer demonstrated slight improvement by atezolizumab and bevacizumab therapy. CONCLUSION: A combination therapy including ICI is a promising treatment option for HCC with concurrent malignancies.
