RESUMO

BACKGROUND/OBJECTIVES: Mushroom consumption, rich in diverse nutrients and bioactive compounds, is suggested as a potential significant contributor to preventing cardiometabolic diseases (CMDs). This systematic review aimed to explore the association between mushrooms and cardiometabolic health outcomes, utilizing data from prospective cohort studies and clinical trials focusing on the general population, with mushrooms themselves as a major exposure. SUBJECTS/METHODS: All original articles, published in English until July 2023, were identified through searches on PubMed, Ovid-Embase, and google scholar. Of 1,328 studies, we finally selected 5 prospective cohort studies and 4 clinical trials. RESULTS: Existing research is limited, typically consisting of 1 to 2 studies for each CMD and cardiometabolic condition. Examination of articles revealed suggestive associations in some cardiometabolic conditions including blood glucose (both fasting and postprandial), high-density lipoprotein cholesterol related indices, high-sensitivity C-reactive protein, and obesity indices (body weight, body mass index, and waist circumference). However, mushroom consumption showed no association with the mortality and morbidity of cardiovascular diseases, stroke, and type 2 diabetes, although there was a potentially beneficial connection with all cause-mortality, hyperuricemia, and metabolic syndrome. CONCLUSION: Due to the scarcity of available studies, drawing definitive conclusions is premature. Further comprehensive investigations are needed to clarify the precise nature and extent of this relationship before making conclusive recommendations for the general population.

RESUMO

The existence of pollutants, such as toxic organic dye chemicals, in water and wastewater raises concerns as they are inadequately eliminated through conventional water and wastewater treatment methods, including physicochemical and biological processes. Ultrasonic treatment has emerged as an advanced treatment process that has been widely applied to the decomposition of recalcitrant organic contaminants. Ultrasonic treatment has several advantages, including easy operation, sustainability, non-secondary pollutant production, and saving energy. This review examines the elimination of dye chemicals and categorizes them into cationic and anionic dyes based on the existing literature. The objectives include (i) analyzing the primary factors (water quality and ultrasonic conditions) that influence the sonodegradation of dye chemicals and their byproducts during ultrasonication, (ii) assessing the impact of the different sonocatalysts and combined systems (with ozone and ultraviolet) on sonodegradation, and (iii) exploring the characteristics-based removal mechanisms of dyes. In addition, this review proposes areas for future research on ultrasonic treatment of dye chemicals in water and wastewater.

RESUMO

As the community food environment is known to be an important factor in healthy food choices, it needs to be measured, to increase awareness and improve healthy eating. The objective of this study was to develop a perceived community food accessibility measurement (P-CFAM) questionnaire applicable to older adults in Korea and evaluate its reliability and validity. The questionnaire was developed based on community food environment factors that were found to affect food choices in previous studies. We evaluated the internal consistency reliability, construct validity, and criterion-related validity. The subjects were 188 older adults for validity. The Cronbach's alpha value for the reliability measure was 0.9. The confirmatory factor analysis to evaluate the construct validity of the questionnaire showed values close to those of the optimal model (GFI = 0.983, AGFI = 0.948, RMR = 0.004, NFI = 0.987, CFI = 0.996). Regarding the criterion-related validity, the P-CFAM questionnaire results were significantly related to objective measurement indicators such as the number of grocery stores, the travel time to a grocery store, and the intake of vegetables and fruit. In conclusion, the developed P-CFAM questionnaire was shown to be reliable and valid, and useful for assessing older adults' perceptions of community food accessibility in Korea.

RESUMO

AIM: To investigate the relationship of energy and macronutrients with physical frailty in Korean older individuals who had a high proportion of energy intake from carbohydrates. METHODS: This study included 954 adults aged 70 to 84 years and used baseline data from the Korean Frailty and Aging Cohort Study (KFACS) collected in 2016. The relationship between energy or macronutrients and frailty was evaluated using multivariable logistic regression models and multivariable nutrient density models. RESULTS: A high carbohydrate intake was related to a higher prevalence of frailty (odds ratio [OR] = 2.01, 95% confidence interval [CI] = 1.03-3.93). In the participants who had low energy intake, replacement of 10% energy from fats with isocaloric carbohydrates was related to a higher prevalence of frailty (10%, OR = 1.59, 95% CI = 1.03-2.43). Regarding proteins, we found no evidence for a relationship between the replacement of the energy of carbohydrates or fats with isocaloric protein and the prevalence of frailty in older adults. CONCLUSIONS: This study showed that the optimal proportion of energy intake from macronutrients may be an important nutritional intervention factor for reducing the risk of frailty among people who are likely to have low energy intake.

RESUMO

An accurate assessment of the recommended calcium (Ca) intake may contribute to reducing the risk of fractures and chronic diseases, ultimately improving quality of life. This review was performed to summarize key findings of Ca studies, investigate the effect of Ca intake on health outcomes, and determine the adequacy of evidence to revise the 2015 Dietary Reference Intakes for Koreans (KDRIs) for Ca in 2020. Databases were searched for intervention studies that assessed health outcomes by providing Ca in diets or as supplements. The framework of the systematic review comprised conducting literature searches, data extraction, quality assessment of the literature, and summarizing key findings relevant to set the Estimated Average Requirement (EAR) and Tolerable Upper Intake Level (UL) for Ca for the 2020 KDRI. The final search was performed in June 2019. A total of 13,309 studies were identified through databases and manual search. Sixtyfive studies were included in the final quality assessment and were summarized according to health indicators. As bone health was used as an indicator of the EAR for Ca, literature reports on bone health were further categorized by the life-cycle stage of the participants. This systematic review did not find new evidence that could be applied to the general Korean adult population, including postmenopausal women, for defining a new EAR for Ca in the 2020 KDRIs. Evidence in most of the reviewed literature was considered weak; however, some evidence was found that could improve the criteria on how the EAR for Ca was determined in children and adolescents. A review of the literature for the 2020 KDRIs for Ca did not find strong evidence in order to change the recommended values of the 2015 KDRIs. More clinical interventions are required among Koreans to strengthen the body of evidence to warrant the revision of the KDRIs.

RESUMO

This study aimed to identify food environment factors in the local community that could affect the levels of nutritional status and frailty in 372 older adults (at least 65 years old) experiencing food insecurity and enrolled in the integrated Community Health Promotion Program (CHPP) in two districts of Seoul. The local food environment was assessed using perceived food store accessibility questionnaires. In order to quantify nutrient intake, the 24-h recall method was applied. Malnutrition was measured using the Mini Nutritional Assessment tool, while frailty was assessed using the Frailty Measurement Questionnaire developed for the CHPP. Malnourished or frail elderly adults commonly had a lower intake of cereals and potatoes, meats, and vegetables than those who were not, and their resulting intake levels of energy, protein, iron, and vitamin groups were also significantly lower (all p-values < 0.05). Among the local community food store environment factors, the sufficiency of food stores (odds ratio (OR) = 1.988, 95% confidence interval (CI] = 1.211-3.262), freshness of foods (OR = 1.767, 95% CI = 1.075-2.886), and variety in foods (OR = 1.961, 95% CI = 1.197-3.212) were significant factors affecting the risk of malnutrition. For frailty, the freshness of foods (OR = 1.997, 95% CI = 1.053-3.788), variety in foods (OR = 2.440, 95% CI = 1.277-4.661), and small purchase of foods (OR = 2.645, 95% CI = 1.362-5.139) were significant environmental factors. In conclusion, we found that the perceived food store environment in the local community can influence the occurrence of malnutrition and frailty in vulnerable, urban older adults.

RESUMO

Wnt and Notch1 signaling pathways play an important role in a variety of biological processes including embryonic induction, the polarity of cell division, cell fate, and cell growth. Although there is evidence that the two main signaling pathways can modulate each other, the precise mechanism is not completely understood. This report shows that beta-catenin can regulate the level and transcriptional activity of the Notch1 and Notch1 intracellular domain (NICD). The in vivo and in vitro results demonstrate that beta-catenin binds with Notch1 and NICD, for which its Armadillo repeat domain is essential. It was further demonstrated that beta-catenin could upregulate the level of Notch1 and NICD, possibly by competing the common ubiquitin-dependent degradation machinery. In addition, beta-catenin enhanced the transcriptional activity of NICD on the hairy and enhancer of split 1 (HES1) and CSL through its C-terminal transactivation domain. This effect of cooperative regulation by beta-catenin could also be observed in bone morphogenetic protein 2 (BMP2) induced osteogenic differentiation of C2C12 cells. beta-catenin coexpression with NICD enhanced the alkaline phosphatase (ALP) activity in C2C12 cells compared with either beta-catenin or NICD expression alone. Culturing C2C12 cells on Delta-1 coated dishes together with Wnt3-conditioned media induced noticeable increases in ALP staining, verifying that employed physiological levels of NICD and beta-catenin are sufficient to induce ALP activation. Furthermore, effects of beta-catenin on Notch1 were dramatically diminished by overexpressed LEF1. Overall, our data suggest that beta-catenin can act as a switching molecule between the classical TCF/LEF1 mediated pathway and NICD mediated pathway.

RESUMO

BACKGROUND: Few investigations have studied the relationship between home and school food environments, fruit intakes, and prevalence of overweight in children and adolescents from disadvantaged backgrounds. This study aimed to determine whether food environments for fruit intake at household and school levels affect fruit intakes and risk of overweight among children and adolescents with low household income. METHODS: Students (n = 3148) in Seoul, Korea completed questionnaires pertaining to select aspects of their food environments, frequency of fruit intakes, and weight status. Chi-square tests and logistic regressions evaluated associations between the aforementioned variables. RESULTS: Participants consumed fruit an average of 0.77 times per day, though its frequency increased when fruit accessibility was perceived positively. The percentage of overweight participants was 23.5% for boys and 22.8% for girls. Generally, fruit intake frequency was linked to a lower prevalence of overweight. Regular provision of fruit in school lunches was associated with a reduced risk of overweight among elementary school girls (odds ratio (OR): 0.52, 95% confidence interval (CI): 0.30-0.92), and having someone at home to prepare fruit was associated with a reduced risk of overweight in elementary school boys (OR: 0.64, 95% CI: 0.43-0.94) and girls (OR: 0.63, 95% CI: 0.43-0.93). CONCLUSIONS: The frequency of fruit intake was low among disadvantaged youth. Increasing access to fruit in their food environments appears to enhance consumption and lower the risk of overweight, especially for elementary school girls.

RESUMO

OBJECTIVE: The objectives of this study were to evaluate the immediate and long-term efficacy and safety of coil embolization for large or giant aneurysms. METHODS: One hundred and fifty large or giant aneurysm cases treated with endovascular coil embolization between January 2005 and February 2014 at a single institute were included in this study. Medical records and imaging findings were reviewed. Statistical analysis was performed to evaluate prognostic factors associated with major recurrence (major recanalization or rupture) and delayed thromboembolism after selective coil embolization. RESULTS: Procedure-related symptomatic complications occurred in five (3.3%) patients. The mean clinical and radiological follow-up periods were 38 months (range, 2-110) and 26 months (range, 6-108), respectively. During the follow-up period, the estimated recurrence rate was 4.6% per year. Multivariate analysis using Cox regression showed the degree of occlusion to be the only factor associated with recurrence (p=0.008, hazard ratio 3.15, 95% confidence interval 1.34-7.41). The patient's history of rupture in addition to the size and location of the aneurysm were not associated with recurrence in this study. Delayed infarction occurred in eight cases, and all were incompletely occluded. CONCLUSION: Although immediate postprocedural safety profiles were reasonable, longterm results showed recanalization and thromboembolic events to occur continuously, especially in patients with incomplete occlusion. In addition, incomplete occlusion was associated with delayed thromboembolic complications. Patients with incomplete occlusions should be followed carefully for delayed recurrence or delayed thromboembolic events.

RESUMO

INTRODUCTION: Irritable bowel syndrome (IBS), known as a functional and organic gastrointestinal disorder, is a collection of symptoms that occur together and generally include pain or discomfort in the abdomen and changes in bowel movement patterns. Due to the limitations of conventional treatments, alternative IBS treatments are used by many patients worldwide. Samryungbaekchulsan (SRS), a herbal formula, has long been used for alleviating diarrhoea-predominant IBS (D-IBS) in traditional Korean medicine. Otilonium bromide (OB) is an antimuscarinic compound used to relieve spasmodic pain in the gut, especially in IBS. Although herbal formulae and Western drugs are commonly coadministered for various diseases in Korea, few clinical studies have been conducted regarding the synergic effects of these treatments for any disease, including D-IBS. METHODS AND ANALYSIS: This trial is a randomised, double-blinded, placebo-controlled, double-dummy, four-arm, parallel study. After a 2-week preparation period, 80 patients with D-IBS will be randomly assigned to one of four treatment groups consisting of SRS (water extract granules, 5 g/pack, three times a day) with OB (tablet form, one capsule three times a day) or their placebos, with treatment lasting for 8 weeks. Post-treatment follow-up will be conducted 4 weeks after the end of treatment. The primary outcome is the finding obtained using the Subject's Global Assessment of Relief method. The secondary outcomes are the severity of symptoms related to D-IBS, determined using a 10-point scale, and the change in symptoms. ETHICS AND DISSEMINATION: This trial has full ethical approval of the Ethics Committee of Catholic Kwandong University International St. Mary's Hospital (IS15MISV0033) and the Korean Ministry of Food and Drug Safety (30769). The results of the study will be disseminated through a peer-reviewed journal and/or conference presentations. TRIAL PROTOCOL VERSION: IS15MISV0033 version 4.0 (25 July 2016). TRIAL REGISTRATION NUMBER: KCT0001621 (approval date: 10 August 2015).

RESUMO

BACKGROUND: Endovascular coil embolization for ophthalmic artery (OphA) aneurysms has the latent risk of occlusion of the OphA during the procedure, which can lead to loss of vision. We report clinical and angiographic results of endovascular treatment of OphA aneurysms together with the efficacy of the balloon occlusion test (BOT). METHODS: From August 2005 to December 2013, 31 consecutive patients with 33 OphA aneurysms were treated in our institution. The patients were classified into two groups according to the location of the OphA within the aneurysmal sac. The BOT was performed in 28 patients using a hypercompliant balloon before endovascular coiling. Collateral circulation between the external carotid artery and the OphA was examined and visual function tests were performed before and after treatment. Patient demographics, angiographic and clinical outcomes were reviewed. RESULTS: Among the 28 patients who underwent the BOT, intact collateral circulation was demonstrated in 26 (92.9%) patients and complete occlusion of the OphA was obtained in three patients after coiling. Retrograde filling of the OphA with choroidoretinal blush was observed on post-procedural angiography and no specific visual symptoms were reported during the follow-up period. Complete embolization was achieved in 30 lesions (96.8%) and only five patients (16.1%) had minor recanalization. CONCLUSIONS: Endovascular treatment of OphA aneurysms can be performed safely and effectively in conjunction with BOT. The BOT may give useful information to predict visual outcome in patients whose OphA is likely to be threatened by the coiling procedure and to determine the optimal treatment strategy.

RESUMO

BACKGROUND: While carotid angioplasty and stenting (CAS) have become an established procedure, outcomes of early CAS for symptomatic extracranial carotid stenosis (SECS) remain poorly understood. The present study aimed at determining the effectiveness of early CAS in SECS. METHODS: Herein, 224 SECS patients underwent elective CAS between January 2008 and June 2015. The study population was stratified based on the time from symptom onset to the procedure (early CAS group: within 14 days; delayed CAS group: later than 14 days). Subgroup analysis (chi-square test, Mantel-Haenszel chi-square test, and analysis of covariance) evaluated the demographics, incidence of periprocedural thromboembolic complications, cerebral hyperperfusion syndrome (CHS), intracranial bleeding, and treatment outcomes on the modified Rankin Scale (mRS). RESULTS: Symptomatic thromboembolic complications and CHS were noted in 2.68% and 0.89% of patients, respectively. The initial National Institutes of Health Stroke Scale (NIHSS) score was significantly higher in patients who underwent early CAS than in those who underwent delayed CAS (2.50 ± 3.97 vs. 0.97 ± 2.08, P = 0.001). After adjusting for age, duration of preprocedural dual antiplatelet therapy, initial NIHSS score, and preprocedural NIHSS score, the groups did not differ significantly regarding the incidence of symptomatic thromboembolic complications (P = 0.195), incidence of CHS (P = 0.950), incidence of intracranial bleeding (P = 0.970), 30-day mRS score (P = 0.124), and mRS score at final follow-up (P = 0.132). CONCLUSIONS: For SECS patients who cannot undergo early carotid endarterectomy, early CAS is effective and safe if selectively indicated considering disease severity. Early and delayed CAS provide comparable mRS scores, incidence of symptomatic thromboembolic complications, CHS, and intracranial bleeding.

RESUMO

OBJECTIVE: Removal of blood from subarachnoid space with a lumbar drainage (LD) may decrease development of cerebral vasospasm. We evaluated the effectiveness of a LD for a clinical vasospasm and outcomes after clipping of aneurysmal subarachnoid hemorrhage (SAH). METHODS: Between July 2008 and July 2013, 234 patients were included in this study. The LD group consisted of 126 patients, 108 patients in the non LD group. We investigated outcomes as follow : 1) clinical vasospasm, 2) angioplasty, 3) cerebral infarction, 4) Glasgow outcome scale (GOS) score at discharge, 5) GOS score at 6-month follow-up, and 6) mortality. RESULTS: Clinical vasospasm occurred in 19% of the LD group and 42% of the non LD group (p<0.001). Angioplasty was performed in 17% of the LD group and 38% of the non LD group (p=0.001). Cerebral infarctions were detected in 29% and 54% of each group respectively (p<0.001). The proportion of GOS score 5 at 6 month follow-up in the LD group was 69%, and it was 58% in the non LD group (p=0.001). Mortality rate showed 5% and 10% in each group respectively. But, there was no difference in shunt between the two groups. CONCLUSION: LD after aneurysmal SAH shows marked reduction of clinical vasospasm and need for angioplasty. With this technique we have shown favorable GOS score at 6 month follow-up.

RESUMO

Vestibular schwannoma (VS) usually present the widening of internal auditory canal (IAC), and these bony changes are typically limited to IAC, not extend to temporal bone. Temporal bone invasion by VS is extremely rare. We report 51-year-old man who revealed temporal bone destruction beyond IAC by unilateral VS. The bony destruction extended anteriorly to the carotid canal and inferiorly to the jugular foramen. On histopathologic examination, the tumor showed typical benign schwannoma and did not show any unusual vascularity or malignant feature. Facial nerve was severely compressed and distorted by tumor, which unevenly eroded temporal bone in surgical field. Vestibular schwannoma with atypical invasion of temporal bone can be successfully treated with combined translabyrinthine and lateral suboccipiral approach without facial nerve dysfunction. Early detection and careful dissection of facial nerve with intraoperative monitoring should be considered during operation due to severe adhesion and distortion of facial nerve by tumor and eroded temporal bone.

RESUMO

Granular cell tumors (GCTs) have been reported in various tissues, especially the skin and subcutaneous soft tissue of the head and neck. We report a 60-year-old man who presented with intermittent headache and dizziness for 3 months, but no other neurological symptoms. Magnetic resonance imaging (MRI) showed the presence of a mass in the pituitary stalk, and contrast-enhanced MRI showed nodular enhancement in this region. The lesion was completely excised microscopically via a frontotemporal (pterional) approach. On pathological examination, a final diagnosis of a typical GCT was made.

RESUMO

Spinal subdural hematoma (SSDH) is an extremely uncommon condition. Causative factors include trauma, anticoagulant drug administration, hemostatic disorders, and vascular disorders such as arteriovenous malformations and lumbar punctures. Of SSDH cases, those that do not have any traumatic event can be considered cases of nontraumatic acute spinal subdural hematoma, which is known to have diverse clinical progress. Treatment typically consists of surgical decompression and cases in which the condition is relieved with conservative treatment are rarely reported. We report two nontraumatic acute spinal subdural hematoma patients who were successfully treated without surgery.
