ABSTRACT
Objectives@#Although a few studies have investigated the relationship between kidney and oral function (number of remaining teeth), their results remain inconclusive. Therefore, this study aimed to investigate the relationship between kidney function and oral health in community-dwelling healthy elderlies and examine the factors associated with kidney function. @*Materials and Methods@#We used cross-sectional data from the Shimane prefecture cohort recruited by the Center for Community-Based Health Research and Education in 2019. We collected clinical data on dental status, background factors and kidney function (estimated glomerular filtration rate [eGFR], mL/min/1.73 m2 and creatinine levels, mg/dL). @*Results@#The study enrolled 481 participants, whose mean age was 66.7±7.4 years, and 223 (46.4%) participants were men. Multivariate analysis revealed significant correlations between eGFR (B=0.17, P=0.04), creatinine (B=–0.54, P<0.01), and the number of remaining teeth. The number of remaining teeth was associated with creatinine and eGFR, which are indicators of kidney function. @*Conclusion@#This study suggests that preserving the teeth may prevent decline in kidney function. Dental professionals should provide instructions and professional care to reduce the risk of systemic diseases such as kidney dysfunction.
ABSTRACT
The U-40 generation of surgeons are practicing through trial and error, and form various careers. At the 51st Annual Meeting of the Japanese Society of Cardiovascular Surgery, U-40 Special Project, we looked back on the U-40 generation and more senior doctors to see what kind of future visions, problems and careers they have had. We conducted a questionnaire for the purpose of visualizing the future prospects of the U-40 generation. In this article, we report the results.
ABSTRACT
Objective: Although oral health and skeletal muscle status are known to be risk factors for type 2 diabetes mellitus (T2DM), there is limited information on their combined effects among community-dwelling older adults. The purpose of this study was to investigate the association between oral health and skeletal muscle status among older adults with T2DM in Japan.Participants and Methods: This cross-sectional study included data from individuals aged ≥60 years. T2DM was defined as a glycosylated hemoglobin A1c level ≥48 mmol/mol (≥6.5%) or the use of hypoglycemic agents. For oral health status, dental hygienists assessed the number of teeth (NT) and masticatory function (MF). Skeletal muscle status was assessed using skeletal muscle mass index (SMI) and handgrip strength (HGS). Logistic regression analysis examined T2DM in nine-category combinations of oral health status (each of the three categories in NT and MF) and skeletal status (each of the three categories in SMI and HGS).Results: T2DM was prevalent in 83 participants (16.4%) and was significantly associated with low NT and SMI (odds ratio [OR] = 5.93, 95% confidence interval [CI]: 1.37–25.73) and low MF and SMI (OR = 4.48, 95% CI: 1.23–16.35) compared to high NT and SMI and high MF and SMI, respectively.Conclusion: Our findings indicate that low muscle mass with tooth loss or masticatory dysfunction is associated with T2DM among community-dwelling older adults. This suggests that maintaining oral health and muscle mass may be an effective strategy for the prevention of T2DM.
ABSTRACT
In the U-40 column, we conducted a questionnaire survey of the U-40 generation on the theme of the specialist system for cardiovascular surgery and reported on the present condition and problems in obtaining certification. With the introduction of a new system, off the job training and participatory training using extracorporeal circulation techniques were newly mandated. In this article, we report the results and discussion of the questionnaire survey regarding the present condition of extracorporeal circulation training for the U-40 generation and the pros and cons of training programs.
ABSTRACT
Objective: Falls in older adults are a major public health issue, and it is unclear whether the neighborhood environment is associated with falls among this group. This cross-sectional study investigated whether hilly neighborhood environmental factors were associated with fall status (falls or fear of falling) in rural Japanese older adults.Materials and Methods: Data obtained from 965 participants aged 65 years and older living in Unnan City, Shimane Prefecture, Japan, in 2017 were analyzed. Fall status was assessed based on the 1-year fall incidence (yes/no) for the past year and fear of falling (yes/no) using a self-report questionnaire. For hilly neighborhood environmental factors, the mean elevation and land slope were assessed using a geographic information system. The logistic regression model examined the odds ratios (OR) and 95% confidence intervals (CIs) of fall status in quartiles for elevation and land slope, respectively, and was adjusted for confounders.Results: Falls and fear of falling were observed in 16.8% and 43.2% of participants, respectively. Falls were associated with elevation (OR 1.99, 95% CI 1.17–3.37 for Q2 vs. Q1; OR 2.02, 95% CI 1.19–3.44 for Q3 vs. Q1) and land slope (OR 1.74, 95% CI 1.04–2.93 for Q3 vs. Q1; OR 1.74, 95% CI 1.04–2.93 for Q4 vs. Q1). Fear of falling was associated with elevation (OR 1.78, 95% CI 1.19–2.65 for Q3 vs. Q1) and land slope (OR 1.51, 95% CI 1.01–2.25 for Q4 vs. Q1).Conclusion: Our study found that elevation and land slope as hilly neighborhood environment factors were positively associated with falls or fear of falling among older adults living in rural Japan. Prospective observational studies that investigate the effects of region-specific environmental factors on falls among older adults should be conducted.
ABSTRACT
We investigated how cardiovascular surgeons get a day off.
ABSTRACT
Objective: Engaging in agriculture greatly affects workers’ lifestyles, particularly related to physical activity. This study aimed to clarify the prevalence of lifestyle-related chronic diseases among workers engaging and not engaging in agriculture in rural areas of Japan.Methods: A total of 4,666 consecutive participants aged ≥40 years (1,929 men and 2,737 women) were recruited during health examinations conducted from 2006 to 2014. For analysis, the participants were divided by sex and age into those engaging in agriculture and those not engaging in agriculture.Results: Engaging in agriculture may be contributing with a low prevalence of dyslipidemia, a constitutive factor of metabolic syndrome, in both sexes between the ages of 40 and 64 years. In the elderly aged ≥65 years, engaging in agriculture may influence the low prevalence of hypertension in men. Hypertension, a strong risk factor for stroke and cardiovascular disease, is very frequent among the Japanese elderly and, therefore, engaging in agriculture may have a significant impact on its prevention and control.Conclusion: In rural areas of Japan, engaging in agriculture may contribute to the control of lipid metabolism in middle-aged individuals and blood pressure in the elderly.
ABSTRACT
A 73-year-old woman presented with epigastric discomfort and lightheadedness. She was admitted to another hospital with congestive heart failure due to severe aortic and mitral regurgitation. However, her heart failure was refractory to medical treatment, necessitating transfer to our hospital for surgical treatment. Emergency surgery was performed for worsening heart failure after admission to our hospital. Intraoperative findings showed aneurysms of the ascending aorta and aortic root and avulsion of the aortic valve commissure between the right coronary and non-coronary cusps. Replacement of the ascending aorta and aortic root replacement using the Florida sleeve method as well as double valve replacement (mitral and aortic) were performed with a favorable outcome. Histopathological examination showed myxomatous degeneration, which suggested that it could have contributed to avulsion of the aortic valve commissure.
ABSTRACT
A 65-year-old man with a history of severe aortic valve regurgitation had undergone aortic valve replacement (AVR) via partial upper hemisternotomy at the age of 50 years. At that time, bioprosthetic valve was implanted. Fifteen years after the valve implantation, he presented with palpitations and chest tightness. Examination revealed bioprosthetic valve failure with consequent severe aortic valve regurgitation. Redo AVR via right anterior mini-thoracotomy was decided as the treatment strategy, and the procedure was successfully completed without complications. The patient underwent extubation on the day of the operation. His postoperative course was unremarkable, and he was discharged 13 days postoperatively. In this case, the patient had previously undergone partial upper hemisternotomy (classified as a minimally invasive cardiac surgery [MICS]) and showed only few adhesions in the pericardium, suggesting that MICS could be beneficial in cases involving re-operation.
