BACKGROUND

Observational studies have increasingly reported transthyretin amyloid cardiomyopathy (ATTR-CM) as an under-recognized cause of heart failure. We report the first ATTR-CM diagnosed via multi-modality imaging in the Philippines signifying an important milestone in recognition and management of this formerly believed rare disease, locally. Utilization of non-invasive imaging such as echocardiography, cardiac MRI and technetium-99m pyrophosphate scintigraphy (PYP) demonstrates the potential for accurate diagnosis as well as timely and appropriate treatment strategies.

An 81/M Filipino with a history of carpal tunnel surgery, post-percutaneous coronary intervention (PCI), had three months’ history of refractory heart failure symptoms despite optimized medical treatment. His 2D-echo showed an ejection fraction (EF): 45%-50%, increased left ventricular (LV) posterior wall thickness with mild basal inferior wall hypokinesia and ECG: atrial fibrillation with low voltage. Speckle tracking imaging showed average global longitudinal strain: - 6.5% with cherry-on-top pattern on polar strain map. Cardiac MRI demonstrated diffuse late gadolinium enhancement from endocardial to transmural layers of biventricular and biatrial walls, highly suggestive of cardiac amyloidosis (CA). Light-chain amyloidosis was excluded by negative serum/urine protein electrophoresis/immunofixation. Tc-99m PYP scan revealed greater myocardial-than-bone uptake with a Perugini score 3 and calculated heart-to-contralateral ratio of 1.7. Congestion was controlled with intravenous loop diuretics and he was discharged stable with metoprolol succinate, dapagliflozin and apixaban. At the time of paper submission, he is currently being evaluated for tafamidis treatment.

The case highlighted the advantage of multi-modality imaging for noninvasive yet accurate identification of the disease. A tailored approach is required in slowing the disease progression and improving outcomes.

Although salt-related behaviors may influence urinary salt excretion in early childhood, this relationship remains unclear. This study aimed to examine salt-related behaviors using data from a salt check sheet and urinary salt excretion parameters using spot urine samples from 4-year-old children. This cross-sectional study included all 4-year-old children who underwent health checkups in Ohnan Town, Shimane Prefecture. The study sample consisted of 109 children (49 boys). Measures from spot urine samples included estimated salt excretion (g/day) and the sodium-potassium (Na/K) ratio. Salt-related behaviors were assessed using a salt check sheet that was completed by the parents or guardians. The associations between salt-related behaviors and urinary salt excretion parameters were analyzed using a generalized linear model. The median (M) and interquartile range (IQR) for urinary measures in 4-year-old children were as follows: estimated salt excretion (M = 4.4, IQR: 3.3-6.2) and Na/K ratio (M = 2.3, IQR: 1.4-3.3). The low frequency of consumption of high-salt foods ("such as pickles, pickled plums, etc." and "noodles such as udon and ramen") was associated with low salt excretion and low Na/K ratio. However, in the case of "consumption of udon, ramen, or other soups", the Na/K ratio was higher for "About half a bowl" and "Some" than for "An entire bowl." Additionally, for "eating out or having convenience-store-bought bento (lunch plate) for lunch", the Na/K ratio was higher for "No" than for "Almost every day." In conclusion, the frequency of high-sodium food intake was associated with both urinary sodium excretion and the Na/K ratio in 4-year-old children. Longitudinal investigations using the 24-hour urine collection method are needed to confirm these salt-related behaviors.

BACKGROUND: Histidine-tryptophan-ketoglutarate (HTK) is a solution commonly used for organ transplantation. However, there is no certified fixed regimen for on-pump heart surgery in neonates. We aimed to retrospectively evaluate the outcomes related to different HTK dosages and to analyze the safety of high-dosage perfusion. METHODS: A total of 146 neonates who underwent on-pump heart surgery with single-shot HTK perfusion were divided into two groups according to HTK dosages: a standard-dose (SD) group (n = 63, 40 mL/kg < HTK ≤ 60 mL/kg) and a high-dose (HD) group (n = 83, HTK >60 mL/kg). Propensity score matching (PSM) was performed to control confounding bias. RESULTS: The SD group had a higher weight (3.7 ± 0.4 vs. 3.4 ± 0.4 kg, P < 0.0001), a lower proportion of complete transposition of the great artery (69.8% vs. 85.5%, P = 0.022), a lower cardiopulmonary bypass (CPB) time (123.5 [108.0, 136.0] vs. 132.5 [114.8, 152.5] min, P = 0.034), and a lower aortic x-clamp time (82.9 ± 27.1 vs. 95.5 ± 26.0 min, P = 0.005). After PSM, 44 patients were assigned to each group; baseline characteristics and CPB parameters between the two groups were comparable. There were no significant differences in peri-CPB blood product consumption after PSM (P > 0.05). The incidences of post-operative complications were not significantly different between the two groups. There were no significant differences in ventilation time, intensive care unit stay, and post-operative hospital stay (P > 0.05). Follow-up echocardiography outcomes at 1 month, 3 to 6 months, and 1 year showed that left ventricular ejection fraction and end-diastolic dimension were comparable between the two groups. CONCLUSIONS In neonatal on-pump cardiac surgery patients, single-shot HD (>60 mL/kg) HTK perfusion had a comparable heart protection effect and short-term post-operative prognosis as standard dosage perfusion of 40 to 60 mL/kg. Thus, this study provides supporting evidence of the safety of HD HTK perfusion.

potassium has been identified as another important factor in skeletal health. We examined the link between potassium intake and bone health among the Korean older adult population.SUBJECTS/METHODS: This retrospective, cross-sectional study included 8,732 men and postmenopausal women over 50 years old who completed the Korean National Health and Nutrition Survey (KNHANES) between 2008 and 2011. Potassium consumption was evaluated using a 24-hour recall method. Bone mineral density (BMD) was measured at three sites (total hip, femur neck, and lumbar spine) by dual-energy X-ray absorptiometry (DEXA). Multinomial logistic regression was used to examine the link between potassium intake and prevalence of osteoporosis and osteopenia, after controlling for potential confounding variables.RESULTS: The BMD of the total femur and Ward's triangle were significantly different according to the potassium intake among men (P = 0.031 and P = 0.010, respectively). Women in the top tertile for potassium intake showed higher BMD than those in the bottom tertile at all measurement sites (all P < 0.05). Daily potassium intake was significantly related to a decreased risk of osteoporosis at the lumbar spine in postmenopausal women (odds ratios: 0.68, 95% confidence interval: 0.48-0.96, P trend = 0.031). However, the dietary potassium level was not related to the risk of osteoporosis in men.CONCLUSION: Current findings indicate that higher dietary potassium levels have a favorable effect on bone health and preventing osteoporosis in older Korean women.]]>

potassium (K), chloride (Cl), urea nitrogen (UN), creatinine (Cr), specific gravity (SG) and osmolality (Osm) were measured. The ratios of urinary Na to other parameters were calculated, and correlations with total measured 24UNa were identified.RESULTS: Average 24-hr urine volume was 1,403 ± 475 mL, and measured 24UNa was 143.9 ± 42.1 mEq (range, 87.1–239.4 mEq). Measured 24UNa was significantly correlated with urinary Na/UN (r = 0.560, P < 0.01), urinary Na/Osm (r = 0.510, P < 0.01), urinary Na/Cr (r = 0.392, P < 0.01), urinary Na/K (r = 0.290, P < 0.01), 24UNa estimated using Tanaka's equation (r = 0.452, P < 0.01) and the Korean formula (r = 0.414, P < 0.01), age (r = 0.548, P < 0.01), weight (r = 0.497, P < 0.01), and height (r = 0.393, P < 0.01) in all spot urine samples. Estimated 24UNa based on the second-void spot urine of the first day tended to be more closely correlated with measured 24UNa than were estimates from the other spot urine samples. The significant parameters correlated with the second-void urine of the first day were urinary Na/K (r = 0.647, P < 0.01), urinary Na/Cr (r = 0.558, P < 0.05), and estimated 24UNa using Tanaka's equation (r = 0.616, P < 0.05) and the Korean formula (r = 0.588, P < 0.05).CONCLUSIONS: Second-void urine is more reliable than first-void urine for estimating 24UNa. Urinary Na/K in the second-void urine on the first day is significantly correlated with 24UNa. Further studies are needed to establish the most reliable index and the optimal time of urine sampling for predicting 24UNa.]]>

BACKGROUND AND OBJECTIVES: Although dietary management is strongly recommended in patients with hypertension, little is known about how many manage their diet and follow the guidelines for hypertension. We investigated the prevalence of dietary management among adults with known hypertension and evaluated their compliance to the dietary guidelines.METHODS: Data from the Korea National Health and Nutrition Examination Survey 2013–2016 were used. Among 15,870 adults aged 30–79 years, 4,162 reported a physician-diagnosed hypertension. Diet management behavior was defined by self-report response. Actual dietary intake was assessed by a 24-hour dietary recall. Dietary quality was evaluated using the Korean Healthy Eating Index (KHEI).RESULTS: Among adults with hypertension, 28.0% reported that they were managing their diet. Those with hypertension consumed significantly less dietary sodium (p value<0.01), but also less potassium (p value<0.01), resulting in no difference of sodium-to-potassium ratio compared to those without hypertension (p value=0.66). Among those with hypertension, diet-managing adults had better KHEI score (66.9, p value<0.01) and consumed less sodium (3,354.3 mg, p value<0.01) than not-managing adults (63.6 score and 3,554.5 mg, respectively). However, total KHEI score was rather lower in those with hypertension (p value<0.01) than those without hypertension and their sodium intake was still over the recommended amount.CONCLUSIONS: More than two-thirds of Korean adults with hypertension did not manage their diet in daily life. More effective strategies are needed to increase the level of compliance with dietary recommendations for people with high blood pressure.

PURPOSE: This study examined the food and nutrient intake of Korean elderly according to the anxiety and depressive condition using the data from the Korea National Health and Nutrition Survey (KNHANES) from 2013 to 2015. METHODS: The participants were 3,504 elderly people over 65 years of age (1,523 in men and, 1,981 in women). The dietary information was analyzed using the 24-hour recall data. The anxiety and depressive state was assessed using the self-reported scale EQ-5D in the quality of life dimension. The subjects were divided into the anxiety · depression group (AD) and non-anxiety · depression group (NAD) according to their anxiety and depressive conditions. RESULTS: In the male elderly, the AD group had a significantly lower education and economic level and higher proportion in living alone than the NAD group. The percentage of eating lunch and dinner alone in the male AD group was higher than that of the NAD group. The female AD group showed less a lower frequency of dinner than the NAD group. The male AD group had a lower consumption of total foods, fish and shellfishes, seaweeds, mushrooms, oils and fats, and seasonings than the NAD group. With regard to the nutrient intake, the male elderly NAD group had more sufficient nutrient intakes than the AD group. In particular, the daily intakes of dietary fiber, riboflavin, niacin, potassium and iron were significantly lower in the AD group. To compare with the nutrient density of the two groups, the vitamin C and niacin intakes were lower in the AD group than in the NAD group. Overall, the nutritional status of the male AD group was significantly lower than that of the NAD group. Meanwhile, the female elderly had showed a smaller difference in nutrient intake according to their anxiety and depressive condition. CONCLUSION: These results of this study show that more nutritional education and emotional support are needed to improve the nutritional status and health of the male elderly with anxiety or depression.

OBJECTIVES: Biofilm formation is critical to dental caries initiation and development. The aim of this study was to investigate the effects of nicotine exposure on Streptococcus mutans (S. mutans) biofilm formation concomitantly with the inhibitory effects of sodium chloride (NaCl), potassium chloride (KCl) and potassium iodide (KI) salts. This study examined bacterial growth with varying concentrations of NaCl, KCl, and KI salts and nicotine levels consistent with primary levels of nicotine exposure. MATERIALS AND METHODS: A preliminary screening experiment was performed to investigate the appropriate concentrations of NaCl, KCl, and KI to use with nicotine. With the data, a S. mutans biofilm growth assay was conducted using nicotine (0–32 mg/mL) in Tryptic Soy broth supplemented with 1% sucrose with and without 0.45 M of NaCl, 0.23 M of KCl, and 0.113 M of KI. The biofilm was stained with crystal violet dye and the absorbance measured to determine biofilm formation. RESULTS: The presence of 0.45 M of NaCl, 0.23 M of KCl, and 0.113 M of KI significantly inhibited (p < 0.05) nicotine-induced S. mutans biofilm formation by 52%, 79.7%, and 64.1%, respectively. CONCLUSIONS: The results provide additional evidence regarding the biofilm-enhancing effects of nicotine and demonstrate the inhibitory influence of these salts in reducing the nicotine-induced biofilm formation. A short-term exposure to these salts may inhibit S. mutans biofilm formation.
